In the XIX century postmortem studies showed association of ischemic brain lesions and plaque formation in carotid bifurcation [1]. Later in 1937 Egaz Moniz performed first angiography while neurologists started to consider connection between carotid and brain lesions, and very soon idea for surgical treatment was born [2]. In 1951, in Buenos Aires, Carrea performed external to internal carotid artery bypass, and published it in 1955 [3]. In the period from 1955-1975 different important cardiovascular surgical groups published their reports about surgical treatment of carotid stenosis in symptomatic patient using different reconstructive procedures. Eastcot, Pickering and Rob in 1954 reported resection of carotid bifurcation and internal to common carotid artery bypass, while DeBakey, then Row and Cooley performed carotid endarterectomy (CEA) – plaque removal instead of bypass [4, 5, 6, 7]. Afterwards idea of plaque removal instead of bypass was accepted widely, and its’ efficacy in stroke prevention was later proved in multiple trials [8, 9, 10, 11, 12, 13].
Still, diverse pathologies of carotid artery were treated even before this obsession with carotid stenosis. French surgeon LeFevre used external carotid artery for flow restoration in case of traumatic lesion of internal carotid artery [14]. In the golden fifties, when carotid surgery was born, other authors reported their experience in treatment of carotid aneurysms [15, 16]. Although Dimitza used resection and reanastomosis, Beall had to use graft interposition. In this position authors were using autologous and synthetic graft with similar results; however in region susceptible to infection, autologous graft was preferred. DeBakey also reported his results in usage of graft replacement in case of carotid trauma [17]. In the beginning of treatment of carotid stenosis there were also reports of different techniques similar to those described in trauma and aneurysmatic disease. Dehnman et al treated carotid occlusion with homograft while Doyle et al used saphenous vein for treatment of carotid stenosis [18, 19]
On the other side, endarterectomy as surgical method for the treatment of stenotic arterial lesions was performed on superficial femoral artery, by Dos Santos, and later with extensive usage of Heparin it gain more success and showed its role in aorto-iliac position [20, 21]. Further experience showed its’ excellent effect in focal stenotic lesions in vessels with large-caliber and high-flow rate. In everyday clinical practice this technique has proved efficient in patients with localized disease limited to the distal aorta or proximal iliac arteries and distal common femoral artery obstructing deep femoral artery orifice (profundoplasty) [22, 23, 24]. On the contrary in extensive atherosclerotic pattern that are more frequent in clinical practice, endarterectomy is technically demanding with poor long term results [25]. Later trough history, short lesions were preferably treated by endovascular means, leaving bypass reconstruction for longer ones, while isolated endarterectomy is becoming almost forgotten except in carotid bifurcation. It is rarely recognized in the literature that in some, not frequent, situations endarterectomy in stenotic carotid artery is not possible or it might be jeopardized. What are modes of reconstruction of carotid artery when CEA fails or is not possible? If bypass or graft replacement is alternative in peripheral occlusive disease, should we apply it in carotid position as well in situations when extensive disease is encountered or technical challenge happens?
The aim of this chapter is to show results and experience of a single high volume center in usage of synthetic graft in the treatment of extensive carotid atherosclerotic disease and to analyze published results related to this topic.
Clinic for Vascular and Endovascular Surgery of the Serbian Clinical Center is located in Belgrade, Serbia, and it was part of the Second surgical clinic, the cradle of cardiovascular medicine in the former Yugoslavia. First vascular procedures were performed in its’ facilities in the sixties (1966) by outstanding pioneers of this, in that time, new branch of surgery – V. Stojanovic and B. Vujadinovic. Figure 1 (A and B). Further development of this institution was supported by the fact that it becomes educational and referral center. Intensive cooperation with leading world centers of excellence, sending its practitioners for education and organizing demonstrational operations in own facilities contributed to popularization and development of cardiovascular surgery in the former Yugoslavia, Balkans and Eastern Europe with consequent progress in treatment of cardiovascular patients in this institution. Later S.Lotina, (Figure 1 - C) successor of Stojanovic and Vujadinovic, has significant role in development of vascular surgery in this institution, since he struggled for segmentation of cardiovascular surgery in the late eighties and middle nineties and eventually achieved expansion of independent vascular department with surgeons and angiologists dedicated to this field. Later, Lazar Davidovic, (Figure 1 - D) one of his pupils, becomes new leader of this department accomplished to improve it to the level of the clinic. After finishing his education with fellowship at Pitié-Salpêtrière hospital in Paris, under the service of Prof Eduard Kieffer, where he improved his experience in aortic and carotid surgery, adopting eversion technique, L. Davidovic brought new modern perspectives in the diagnosis and treatment of vascular patients not only in this institution but rather in the whole country of Serbia. Since then the number of carotid and aortic procedures is annually increasing in this institution reaching almost 600 carotid and almost 500 aortic in the year 2011, with sensible and gradually introduction of endovascular procedures (carotid, peripheral stenting and endovascular repair of aortic pathology) according to published results, guidelines recommendation and available financial support of national health care system.

In the period from January 2003 to October 2006, at the Clinic for Vascular and Endovascular Surgery of the Serbian Clinical Centre, 1250 procedures due to carotid artery stenosis in 1127 patients were performed. Carotid stenosis was repaired by eversion or conventional endarterectomy (CEA) and synthetic graft (Dacron®) interposition in 987 (78, 96 %), 205 (16, 4 %) and 58 (4, 64 %) patients respectively. We retrospectively analyzed prospectively gathered data related to the subgroup of patients operated with graft replacement.
Indications for conventional EA with usage of protective intraluminal shunt were contralateral occlusion, recent stroke or transitory ischemic attack and intraoperative stump pressure below 40mmHg. These patients were excluded from this analysis. Other patients were operated with eversion technique. Eversion EA was performed in the same manner as described elsewhere in the literature [26].
Indications for graft replacement (GR) were: extensive atherosclerotic disease proximal and/or distal to carotid bifurcation revealed intraoperatively during dissection or preoperatively by means of ultrasound, digital subtraction angiography (Figure 3.) or multidetector computed tomography; long segment of thrombotic surface after EA; bad quality of arterial wall after EA; inadequate end of the endarterectomy cleavage; any other technical problem that could endanger the success of procedure. Decision for GR was made by operating surgeon.
GR was performed after complete resection of carotid bifurcation and its removal. Dacron graft of 6 or 8 mm in diameter was used depending on the ICA and CCA diameter. Initially anastomosis between the graft and ICA was made, in the continuous fashion, “parachute” technique, with Prolene 6-0 suture. Upon finishing the anastomosis clamp was removed proximaly on the synthetic graft in order to verify anastomotic compatibility. Afterwards proximal anastomosis between CCA and synthetic graft was sutured with Prolene 5-0 in the same fashion. Flushing and air removal is of outmost importance before declamping since there is in-line flow directly to endocranial vascular bed without any patent branch. Reattachment of ECA was performed selectively according to its quality, position and already spent time for GR (Figure 2 and 3.).

In this period of time (2003-2006) cervical plexus block was introduced for carotid surgery in our institution, and consequently we changed the indications for conventional endarterectomy and shunt usage performing it only in case of neurological deterioration of the patient during carotid cross clamping. However patients treated with conventional EA with extensive atherosclerotic disease were not analyzed in this paper and GR was performed without usage of the intraluminal shunt.
Among 1045 procedures performed in 956 patients there were 987 (94, 45%) treated with eversion EA and 58 (5, 55%) with GR. After excluding patients treated with conventional and eversion EA, we retrospectively analyzed preoperative, intraoperative and postoperative data of the patients treated with GR in order to investigate results of this alternative procedure and to try to define optimal indications for its’ usage. After analyzing initial results deeper investigation was performed by dividing group of patients treated with GR in two groups according to the indication and decision to perform GR:
Group A, when decision to perform GR was made according to the ultrasonography exam and intraoperative findings before any attempted EA;
Group B when GR was made after failed EA as a bailout procedure.
In the preoperative data we analyzed age, sex, co-morbid conditions and preoperative ultrasound descriptions. All patients were preoperatively examined by ultrasonography means, describing quality and length of the plaque. All exams were made by experienced ultrasonographer. The quality of plaque was described as lipid, fibrous or calcified with or without present ulceration. The length of the plaque was defined as the longitudinal extent of the plaque narrowing arterial lumen for 30% and more. Plaques longer than 4cm were named as long.
After removing atherosclerotic plaque from internal carotid artery (ICA) and common carotid artery (CCA) its’ quality (morphology) and length were assessed too. From intraoperative data we used the intraoperative length of atherosclerotic disease, reasons to perform GR (before any attempt to perform eversion or after attempted eversion), cross clamping time and restoration of external carotid artery flow.
Postoperative data were related to the neurological outcome and mortality rate as well as early surgical (hemorrhage, cranial nerve lesions, and wound infection) and cardiac complications. All patients were followed for one month and yearly thereafter with clinical and ultrasound examination.
Among treated patients significant number was symptomatic - 30 (51, 72 %) patients with previous transitory ischemic attack (12 – 40%), ocular symptoms (2 – 6, 66%) or stroke (16 – 53, 33%). Demographic characteristics of the patients and symptoms distribution were presented in the Table 1. There was no significant difference in terms of co-morbid conditions between the groups.
Demographic characteristic of the patients and preoperative symptoms
There was no significant difference between ultrasonography and intraoperative findings in the group A. There was significant difference between ultrasonography and intraoperative findings of the plaque length on the CCA and ICA among patients of group B. There was significant number of patients with plaque length of 4cm and more in the CCA, described in the ultrasonography exam and found intraoperatively. Tables 2 and 3\n\t\t\t

Intraoperative data were presented in the table 4. Among 58 patients, 22 (37.93%) were operated in conditions of general anesthesia and 26 (62.07%) under cervical plexus block. Mean cross clamping time was measured and presented in Figure 2. There was significantly longer cross clamping time when GR was made after attempted EA. ECA flow restoration was made in 9 (15.6%) patients with intraoperative decision of the operating surgeon according to the quality of ECA, its’ position related to the implanted graft and elapsed time of the procedure. Reimplantation of ECA did not influence on neurological complication rate.
Early postoperative recovery was uneventful in 36 patients (95%). Early death was reported in 2 patients (5%), due to fatal stroke in the early postoperative time. More one patient had transitory ischemic attack (2,5%) and one had minor stroke (2,5%). Total rate of neurological complications is 7.5%. Comparison of the neurological complications between the groups found higher rates when EA was unsuccessful and GR performed as a bail out procedure. Permanent cranial nerve injuries were reported in 1 patient (2.5%). There was neither early myocardial infarction nor death based on any other cause in this series.
Patients were followed by means of ultrasonography one month after the procedure and yearly thereafter. Mean follow up time was 32 months. Two patients were lost from follow up while 4 patients (10.52%) died during this period of time. Restenosis of less than 75% was reported in 2 patients (5.26%), restenosis of 75-99% was found in 1 patient (2.78%) successfully treated with carotid stenting (Figure 5). In one patient total occlusion of reconstructed artery was revealed with no neurological symptoms.

There is no doubt that, over all, endarterectomy is the optimal technique for surgical repair of carotid stenosis. This is the only location where EA is the preferable method nowadays. Choice of EA (conventional or eversion) might cause some discussion between vascular surgeons however the last meta-analysis gave slight advantage to eversion, which was also shown by randomized trial in our institution [27, 28]. Previous Meta analysis showed no difference between the two techniques [27]. The former includes a standard longitudinal carotid arteriotomy with or without patch angioplasty, whereas the second encompasses an oblique transection and eversion of the internal carotid artery and its’ reimplantation into the common carotid artery [29, 30, 31]. Regarding the carotid artery closure after conventional EA, carotid patch angioplasty is preferable to primary closure [32].
Conventional EA requires usage of graft material that is extending procedure and expose patient to the risk of infection [33]. Eversion EA on the other side does not provide sufficient insight in to the complete endarterectomized surface in the zone at the end of the removed atherosclerotic plaque. Also preparing carotid bifurcation for eversion EA requires its complete deliberation from surrounding tissue which might increase the risk of distal embolizations. Elongated internal carotid artery makes patch suturing more complex while shunt placement in these situations is raising the difficulties. Redundant ICA might simplify eversion EA on the other side. Both of these techniques are related to some advantages and disadvantages including surgeons’ familiarity as a specific one. Both of the techniques requires volume of patients in order to achieve good results what might influence the diverse adoption between the teams. According to one multinational registry there is difference in the usage rate of these techniques – in eight European countries EA was performed without patch (34%), with patch (40%) or with eversion (26%). Finally, guidelines of the most important and leading societies are leaving the choice between the two techniques to the operating surgeon [32, 34]. Does it mean that any procedure that removes atherosclerotic plaque from carotid bifurcation and restores flow in a short and long term would be effective in stroke prevention? The similar theory said M.E. DeBakey sixty years ago before his first carotid procedure. DeBakey reasoned that, since endarterectomy and graft replacement in other arteries could be performed, the carotid artery should not be an exception [35].
Carotid stenosis is most frequently localized at the carotid bifurcation leaving proximal and distal segments free from disease providing suitable conditions for endarterectomy. Extension of the atherosclerotic process towards proximally or distally might make endarterectomy cumbersome and risky, while multiple severe atherosclerotic changes at different levels of supra-aortic branches require anatomical or extra-anatomical bypass procedure. Group of patients analyzed in this chapter belongs somewhere between these two patterns of carotid disease – not enough extensive for anatomical bypass through sternotomy while substantially extensive and challenging for eversion EA.
From technical point of view atherosclerotic process that extends proximally and/or distally aggravates endarterectomy jeopardizing the procedure. Initial problem is carotid clamping. It is necessary to extensively dissect internal and common carotid artery in order to provide safe clamping. Clamping at inadequate location of diseased artery might cause plaque rupture with consequent prone to thrombosis causing perioperative embolizations. Also, clamping at inadequate location could cause incomplete EA causing thrombosis especially at the internal carotid artery location. Preventing incomplete EA in this situation requires additional dissection which is more challenging during clamped and transected carotid artery, it prolongs cross clamping time and might stress inexperienced surgeon provoking other mistakes. Reaching healthy zone is important likewise for shunt users in order to prevent placing a shunt through atherosclerotique plaque inducing distal embolizations. Once reaching the conform clamping zone we are faced with technicaly demanding extensive EA. In case of eversion technique problems are visualization of the end of the plaque zone, adequate flushing of the left surface and removal of small residual intimal particles that are prone to mobilization causing distal embolizations [36]. Extensive dissection of internal carotid artery and its deliberation from surrounding tissue facilitate its eversion. On the contrary, common carotid artery is even more difficult to evert through the whole circumference since the posterior wall is fixed with the external carotid artery. Due to that flexibility of common carotid artery depends on deliberation of external carotid artery from surrounding tissue too. In case of extensive athersoclerosis of common carotid artery and average to minimal process on internal carotid artery it is advisible to transect common carotid artery proximal from its’ bifurcation instead of transecting internal carotid artery. This techniqe provides easier EA of common carotid artery in a longer segment [7]. Another technical possibility to deal with extensive atherosclerotic disease in common carotid artery could be semi closed endarterectomy by using Vollmars rings. Finally, for those who preffer conventional technique the very process of EA is quite easier with adequate visualisation of the end of the plaque zone, however, finally the Achille heel of this method is long patch anastomosis that is technicaly demanding and more prone to neointimal hyperplasia or false aneurysm. Anastomotic bleeding on the long patch is another technical difficutly especialy when using intraluminal shunt. Upon removing the shunt, brain perfusion is reduced until complete haemostasis is provided making declamping safe. Loosing time on resolving anastomotic bleeding could cause ishemic brain injury. Overcoming all these technical difficulties does not guarantee sucess since long endarterectomy is leaving long thrombogenic surface prone to in situ thrombosis or distal embolizations jeopardizing the results of the procedure regardless to excellent surgical technique.
All these difficulties were encountered in peripheral vascular surgery inducing usage of different conduits in the reconstructive bypass procedures; similar was done in carotid surgery although less frequently. Bypass in this location could have a good long term potential since it is connecting two healthy arteries with high blood flow and loaded recipient vascular bed, like cerebral, which is inducing low resistance. Still low number of publications is describing this technique in the last 30 years with usage of different conduits. Consequently in the two most respected guidelines for treatment of carotid stenosis this option is not mentioned. However a short review of the published data related to this technique is given below with some technical remarks from the authors of this chapter.
In 1979 M.E.Debakey published his experience in usage of synthetic graft for repair of carotid artery injury [37]. In the same year Cormier and all started to use this type of reconstruction reporting their experience eight years later [38]. Among 62 treated patients 54 (87%) were treated due to extensive atherosclerotic disease, with 5% stroke rate and 97% patency in the 23 months long term follow up. Later, different types of reconstruction were reported using various conduits. Camiade and all used PTFE graft suture with side to end proximally and end to side anastomosis distaly [39]. This technique minimizes dissection of carotid bifurcation and preserves patency of external carotid artery. Authors performed this procedure in 110 patients, indicated it in case of extensive atherosclerotic disease in 45 (41%), while using it also for reconstruction in case od restenosis (16.4%) or kinking (26.4%). There were some other authors reporting usage PTFE graft with similar patency of 95-97% in the long term [40, 41]. The only author that used Dacron graft was Valdeniz with results comparable to those published with PTFE [42]. Autologous saphenous vein was also reported by various authors, some of them complaining on high restenosis rate. French authors are reporting good early and long term results [43, 44, 45]. In 212 patients treated due to extensive atherosclerotic disease (76%), restenosis (5.6%), kinking (8.49%) and aneurysm (4.24%) they reported 5% stroke rate and 96% patency after average 104 months of follow up. On the other side according to the Leicester group saphenous vein is prone to early restenosis in this position even though they performed different anastomotic techniques [46]. According to the diameter of the vein graft and common carotid artery they located anastomosis at the lateral wall of common carotid artery, at the origin of internal carotid artery or at the origin of external carotid artery after its’ exclusion. After average follow up of 60 months patency rate was 83% with significant incidence of restenosis. According to opinion of the authors of this chapter vein graft could be perfect for this procedure, however one might expect misfit of the calibers. Additionally harvesting this graft could be time consuming if so if the graft replacement is performed as a bailout procedure it might prolong cross clamping time and procedure. It is not convenient for carotid procedures performed in cervical plexus block and finally saphenous vein is important conduit for coronary revascularization and should be preserved for that occasion as well. This conduit could be unavailable in patients with varicose syndrome and previous coronary revascularization. Latest publication is from W. Moore reporting 17 years of experience using both synthetic and saphenous vein grafts with satisfying results [47]. 31 PTFE and 10 saphenous grafts were followed for 50 months with patency of 90% and 80%, respectively. Carotid graft replacement is already proved procedure in some other pathology like carotid artery aneurysm and restenosis [48, 49].
Summarized published data show 613 carotid procedures where bifurcation was reconstructed with GR. In all these publications the most frequent indication for graft usage was extensive atherosclerotic disease with involvement of common or distal internal carotid artery – 328 procedures (53.5%). Other indications were carotid recurrent stenosis, technical failure of attempted EA, stenosis after radiation therapy, carotid aneurysm and carotid stenosis associated with kinking. Among 613 carotid stenosis treated with GR, 290 (47,3%) procedures were performed with PTFE graft, 272 (44,37%) with saphenous graft and 51 (8,31%) with Dacron. Extensive and detailed information regarding published data are shown in the Table 4.
When it comes to carotid stenosis, EA is the method of choice in majority of patients. Small subgroup of patients had extensive carotid atherosclerotic disease that involves common or internal carotid artery in a segment longer than 4cm. In these situations modification of surgical procedure is necessary since EA might be jeopardized. Optimal scenario would be to assess extension of atherosclerotic process preoperatively through ultrasonography or MSCT angiography or intraoperatively during dissection of carotid arteries. In case of extensive atherosclerotic process, decision to perform carotid graft replacement without any attempt of EA could simplify procedure, shorten cross clamping time and avoid technical and thromboembolic complications. Conduit choice is the matter of operating surgeon. Upon clamping and resecting diseased segment, suturing distal anastomosis first is recommendable in order to provide easier manipulation and better visualization of anastomotic line. Next step is suturing the proximal anastomosis then flushing and finally carotid declamping. Reimplantation of external carotid artery is not mandatory and the decision should be made as the preference of the surgeon. Efforts to perform EA even in case of extensive disease could be effective especially in experienced hands, however in case of any doubts in wall quality or end of the plaque zone, graft replacement should be performed before flow restoration in order to prevent fatal complications that this procedure carries.
There is not enough evidence to provide any accurate criteria for usage of carotid graft replacement instead of endarterectomy. This chapter showed results, experience and technical details of a single high volume center and presented not so reach published material. Decision to perform graft replacement should be made individually according to anatomy and morphology of carotid disease. Wide surgical experience affords expertise and improves individual decision making.

Under conditions of psychological dysregulation or disease, pain can lose its physiological role and take on an aberrant course, resulting in chronic pain syndromes [1].
As doctors, we often take care of patients who describe chronic pain all over the body, which is associated with a range of other symptoms including poor sleep, fatigue, and depression. This complex of symptoms is sometimes referred to as functional somatic syndrome, part of a somatization disorder, idiopathic pain disorder, or psychosomatic syndrome, dismissing the true suffering of the patients [2]. By reason of that, it is not unusual for patients to see at least four physicians before the diagnosis is made.
At the present time, we know that fibromyalgia (FM) is a nonprogressive and nondegenerative syndrome with a spectrum of symptoms that most commonly include generalized chronic pain. It affects 0.4–8.8% of the general population worldwide, with a global mean prevalence of 2.7%, with women outnumbering men by an average of 3:1 [3].
FM is defined as a central sensitization syndrome characterized by chronic extensive “centralized pain.” Central sensitization, as well, is defined as the process of becoming susceptible to a given stimulus that previously had no effect or significance (i.e., pressure, light, medication, temperature) [4]. This increased central responsiveness causes hyperalgesia, allodynia, and pain across multiple spinal segments, leading to chronic widespread pain [2].
Although FM is commonly classified as “functional,” because its etiology, pathogenesis, and symptoms are not completely explained, rheumatologists, pain specialists, and increasingly primary care providers are gaining confidence in making this diagnosis and initiating treatment [5].
Historically, its definition and content have changed repeatedly in the more than 100 years of its existence. Different terms have been proposed by the medical science [6, 7, 8, 9, 10, 11, 12, 13, 14], which summarizes the lack of understanding of this argumentative condition, which has evolved from a regional pain disorder to a multiple symptoms disorder [15] (Table 1).
Disorders | Features |
---|---|
Neurasthenia Nervous exhaustion | Pathological entity in which there is a functional nervous dysfunction manifested by marked fatigability and irritability affecting various organs and functions without any demonstrable pathological tissue changes [6]. This term was abandoned in the 1930s |
Fibrositis | Inflammation of white fibrous tissue wherever situated (panniculitis, interstitial neuritis, myositis, bursitis, capsulitis, etc.). In this sense these terms merely indicate the position of the fibrous tissue which is implicated. Tenders point needed. Widespread aching. Fatigue [7, 8, 9] |
Chronic fatigue syndrome Myalgic encephalomyelitis | Medical condition characterized by symptom clusters that include pathological fatigue and malaise that is worse after exertion, cognitive dysfunction, immune dysfunction, unrefreshing sleep, pain, autonomic dysfunction, neuroendocrine, and immune symptoms [10, 11] |
Burn out | Represents the total depletion of one’s physical and mental resources [12] |
Chronic widespread pain (CWP) | A pain variable that would identify potential FM patients. It represents a categorical designation of musculoskeletal body pain defined by the location, distribution, and number of painful musculoskeletal body locations or sites [13, 14] |
Fibromyalgia-like conditions.
Nowadays the ICD-11 considers FM to be a form of chronic widespread pain (CWP) [16, 17], besides it considers CWP a form of chronic primary pain (MG30.0) and is present when:
Chronic pain (persistent or recurrent pain for longer than 3 months) is present in at least three body quadrants plus the axial skeleton (4 of 5 regions).
The pain is associated with at least one of the following:
Emotional distress due to pain is present.
The pain interferes with daily life activities and social participation.
The pain is not better accounted for by another chronic pain condition.
This definition seems to define a CWP as a disease or disorder. Neither FM nor CWP is obviously a distinct entity.
In addition to the direct physical suffering that patients experience, the biopsychosocial nature of chronic pain affects their social lives, ability to work, and psychological well-being. People with FM often reported dismissive attitudes from others, such as disbelief, stigmatization, lack of acceptance by their relatives, and friends, and doctors may consider them as lazy or attention seeking people, with their symptoms all in their head [2]. Such disdainfulness can have a substantial negative impact on patients, who are already distressed [18]. Furthermore, patients have an increased lifetime prevalence of many psychological disorders.
The primary purpose of this paper is to provide an approach to FM from three points of view of processing: the viewpoint of the medical profession, the position of the psychologist, and finally, social aspects.
The medical profession:
Diagnostic criteria of FM
Pathogenesis
What causes FM? Predisposing factors
Comorbidities:
Other central sensitivity syndromes
Psychiatric
Nonpsychiatric: rheumatology
The position of the psychologist:
Psychosomatic disease?
Emotional dysregulation
Address the psychological in FM:
Our experience
The main topics from a psychological point of view
Social aspects. Impact at three levels:
Family
Labor
Health system
Diagnosing FM is quite challenging because there is an absence of a univocal identified biological cause [19].
Although two methods are used in the diagnosis, criteria-based and clinical one, FM remains a controversial interpretation, with some studies suggesting that FM is overdiagnosed and other reporting that community physicians have limited knowledge of FM diagnosis and criteria:
FM became officially established by formal criteria in 1990 [20], after which a multiplicity of symptoms became a central component of the illness. Nowadays there is evidence in support of FM as a dimensional or continuum disorder [21, 22] which is included in the international list of diseases of the World Health Organization [17] (Table 2).
American College of Rheumatology (ACR) | Criteria stablished | Clarification |
---|---|---|
1990 Wolfe et al. [20] | Chronic widespread pain (CWP) + Pain in 11 of 18 tender point sites on “digital palpation” | CWP: Simultaneous pain in the axial skeleton, in the left and the right side of the body, and above and below the waist, for at least 3 months “Digital palpation” should be performed with an approximate force of 4 Kg Tender point positive: the subject must state that the palpation was painful |
2010 Wolfe et al. [21] | Widespread pain index (WPI) + Symptom severity scale (SSS): Fatigue Waking unrefreshed Cognitive symptom | WPI: areas with pain over the last week SSS: the sum of the severity of the three symptoms plus the extent (severity) of somatic symptoms in general “It does not require a tender point examination” |
2011 Wolfe et al. [22] | Widespread pain index (WPI): Left Shoulder Right Lt. Upper Arm Rt. Lower Lt. Hip Rt. Lt. Upper Leg Rt. Lower Lt. Jaw Rt. Chest Abdomen Upper Back Lower Neck + Symptom severity (SS) score: Fatigue Waking unrefreshed Cognitive symptom |
SS score: For the each of these three symptoms, indicate the level of severity over the past week using the following scale: 0 = no problem; 1 = slight or mild problems; generally mild or intermittent; 2 = moderate; considerable problems; often present and/or at a moderate level; 3 = severe: pervasive, continuous, life-disturbing problems The SS score is the sum of the severity of the three symptoms plus the sum of the number of the following symptoms occurring during the previous 6 months: headaches, pain or cramps in lower abdomen, and depression (0–3). The final score is between 0 and 12 |
Fibromyalgia criteria according to the American College of Rheumatology.
In 2016, the widespread pain criterion was reinstalled; thus FM diagnosis requires:
Widespread pain index (WPI) ≥ 7 and symptom severity scale (SSS) ≥ 5 or a WPI of 4–6 and an SSS score ≥9
Presence of widespread pain (pain in four or five body regions)
Symptoms of at least 3 months of duration
Classification criteria may help guide a diagnosis but are primarily useful for research and epidemiological studies.
It is based on the physician/patient relationship. FM, because of symptoms’ intensities (pervasive fatigue, abdominal cramps, headaches, disturbed sleep, muscle spasms, stiffness, tenderness, reduced physical, social and cognitive functioning, depressed mood, anxiety, and irritability), constitutes a heterogeneous disorder in which “chronic widespread pain” is dominant [23, 24, 25, 26, 27, 28]. Moreover, FM differs from the “chronic widespread pain” by its inclusion of non-pain symptoms, including severity measures of fatigue, unrefreshed sleep, cognitive problems, and somatic symptoms [29].
Common manifestations in FM are hyperalgesia (excessive sensitivity to a normally painful stimulus, such as pressure), allodynia (painful sensation to a normally non-painful stimulus, e.g., touch and massage), expansion of the receptive field (pain beyond the area of peripheral nerve supply), prolonged electrophysiological discharge, an after-stimulus unpleasant quality of the pain (e.g., burning, throbbing, tingling, or numbness), and referred pain across multiple spinal segments, leading to chronic widespread pain [20]. The number of pain sites is strongly correlated with somatic and psychological symptom burden in the general population. An example of making a record of the pain sites is by the “Michigan body map” [30] (Figure 1).

Quantitative sensory testing should be undertaken to determine if augmented response is present or absent, using pressure, pinprick, cold, heat, vibration, electricity, ischemia, and chemical (capsaicin, hypertonic saline) stimuli. Patients should be tested for allodynia (using cotton swab, brush, Von Frey filaments), temporal summation, conditioned pain modulation, and nociceptive flexion reflex.
All common conditions, like depression or FM, are caught in the dilemma of disease versus illness state (of health) versus trait (characteristic feature distinguishing a particular human being).
Given the high incidence of chronic pain, it is fundamental to understand basic processes underlying this kind of suffering: repeated stimulation of the centripetal nerves overtime causes changes to the way the pain signals are processed, leading to a pathophysiological state where the nervous system is sensitized and the perception of pain becomes heighten.
Both the peripheral and the central nervous system can become sensitize to pain signals in response to injury or inflammation nociceptors. The periphery can become more sensitive to painful stimuli, a process called “peripheral sensitization.” These sensitize nociceptors and then send additional pain signals to the CNS which can lead to the overstimulation of the CNS.
“Central sensitization” is a proposed physiological phenomenon in which dysregulation in the central nervous system (imbalance between pain transmission and pain inhibition) causes neuronal dysregulation and hyperexcitability, resulting in hypersensitivity to both noxious and non-noxious stimuli and the perpetuation of pain [31] (Figure 2).
Physiological pathways of pain. The activated C fibers express, at their nerve terminals, several neurotransmitters: Substance P (SP), nerve growth factor (NGF), calcitonin gene-related peptide, vasoactive intestinal peptide, glutamate (GLUT), aspartate, and brain-derived neurotrophic factor. These chemicals cause a barrage of impulses at the synapse that now hyperexcite the postsynaptic receptors: neurokinin1 (NK1), N-methyl-D-aspartate (NMDA), metabotropic glutamate, tyrosine kinase B (TrK-B), and protein kinase gamma. Activation of these receptors results in a remarkable physiologic change in the postsynaptic nerve cells, including membrane changes, intracellular influx of calcium, protein kinase activation, and expression of protein c-fos (marker for neuronal activity following peripheral stimulation). These changes cause an intensification of hyperexcitability of the second-order neurons, giving rise to hypersensitivity to various peripheral stimuli. “Central sensitivity”: perturbation in the central processing of sensory information that amplifies the response of the central nervous system to a peripheral input.
Central sensitization has been proposed as the root etiology for “central sensitivity syndromes” (CSS), which refer to a group of medically indistinct disorders for which no organic cause can be found. A number of authors state that the CSS symptoms are not medically explicable and are psychiatric, psychological, or psychosocial in nature [32, 33, 34]. Therefore, people with FM suffer from abnormalities in the central pain processing, what implies a lower threshold for interpreting sensory information as noxious, in addition to an increased excitation’s mechanism or reduced inhibition’s ones. This plays an important role in the development and maintenance of chronic pain.
On the other hand, some aberrations of the peripheral nervous system, as an antidromal axonal reflex of C fibers in response to a stimulus, may initialize neuroendocrine processes and vascular permeability. These processes encompass the phenomenon of neuro-inflammation, in which stress and other psychological factors induce these neural responses to amplify the pain perception.
Abnormal sensory and pain processing is the key factor in the pathophysiology of FM [35], and in addition, sensitization heightens the perception of pain.
There is evidence for excessive pain-related neuronal activity at multiple levels of the central nervous system, structural and functional changes in the brain by imaging studies, and impaired function of normal descending inhibitory mechanisms [29].
Several factors, such as genetic predisposition or alteration in the expression of several genes (epigenetic mechanisms), deficiencies in neurotransmitter levels, biochemical changes in the body, endocrine dysfunction, certain types of infections (e.g., Epstein-Barr virus, Lyme disease, Q fever, viral hepatitis), mood states, sociocultural environment (early-life stress or adversity), psychological trauma, and past experiences in general (e.g., childhood or sexual abuse), have been proposed as explanatory mechanisms of patients’ subjective experience of central sensitivity and subcortical nociceptive transmission [28, 36, 37, 38, 39, 40, 41, 42, 43].
Genes associated with increased or decreased frequency of chronic pain states or pain sensitivity regulate the breakdown or binding of pain sensitivity-modulating neurotransmitters and other inflammatory pathways. Candidate genes implicated in FM include those controlling serotonin mechanisms, dopamine receptors, as well as metabolism of catecholamines [44, 45].
A recent review confirmed the key role of neurobiological substrates, including the hypothalamic-pituitary-adrenal (HPA) axis, monoaminergic, opioidergic, endocannabinoid, and immune systems, as well as some epigenetic mechanisms, in the association of early-life psychological stress and the risk of chronic pain in later life [40]. Early psychological trauma can alter the HPA axis response, which may result in the dysfunction of peripheral and spinal dorsal horn neurons, excitatory amino acids, and central neuropeptides that can lead to abnormal nociceptive input to the brain when there is no actual painful stimulus, resulting in a central sensitization syndrome [46, 47]. Similarly, many people with FM exposed to early abuse have anxiety, depression, and post-traumatic stress disorder [2].
Patients with FM appear to have specific gut microbiome alterations that differ from their healthy peers. Recently Clos-García et al. have found an alteration in glutamate metabolism (possible molecular biomarker) connecting the gut microbiome with the brain through the enteric nervous system. This alteration has been associated with psychiatric and gastrointestinal disorders [48].
Finally, there is no scientific support for the idea that physical trauma (e.g., motor vehicle accidents) causes FM [49].
Pain, fatigue and other distressing sensations, occurring in the absence of clinically obvious pathology are common health problems in medical practice. Such experiences are never uniform, yet symptoms often present together in stereotypically recognizable ways. Several criteria were suggested for classification of a disease as a member of the CSS group: (a) the presence of CS; (b) the absence of an underlying disease (primary conditions), and (c) mutual associations between the disorders.
Recently, Yunus proposed a number of ailments included in the list of CSS family: irritable bowel syndrome, primary (dysfunctional) dyspepsia, tension-type headache, migraine, myofascial pain syndrome, myofascial temporomandibular disorder, primary chronic neck pain, primary low back pain, restless legs syndrome, periodic limb movement disorder, and endometriosis, among others [42].
Because of the mutual associations between the disorders, the differential diagnosis of FM is difficult.
Patients relate too many symptoms, and the symptoms appear too severe and too unusual, and the patients too healthy compared with patients with other pain disorders [15].
A recent clinical review summarized that 62% of FM patients showed major depressive disorder, 11% bipolar disorder, 29% panic disorder, and 29% social phobia [50].
Mental disorders, especially mood disorders, have been associated with a negative impact on pain, fatigue, sleep, physical functioning, and quality of life in FM [51].
It is said that non-arthritic rheumatism frequently covers anxiety states. The musculoskeletal pain or fatigue associated with other disorders may mimic those of FM and vice versa. Additionally, there are many similar disorders, which are not exclusive of FM, and will overlap concomitantly. The broad categories are the following [52]:
Inflammatory and autoimmune disorders, including rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome, polymyalgia rheumatica, and spondyloarthritis
Muscle disorders and myalgias
Myofascial pain syndrome, temporomandibular joint dysfunction, lower back pain
FM, as a paradigm of psychosomatic disorders, would have different repercussions:
Physical (inactivity, disability) that leads the person to a sick and invalid role
Psychological, resulting in emotional disturbances, vulnerability to substance abuse, etc.
Social, such as tendencies towards isolation, interpersonal conflicts, etc.
Sometimes pain becomes the center of life for the patients, leading to a successive demand for assistance, conflicts with professionals, etc.
Regarding the psychological point of view, pain has been approached from the theories of traits, psychodynamic thesis, behaviorism, neuropsychology, etc., since the cognitive perspective is one of the most relevant today, specifically the study of beliefs and internal language of the patients. Along with this, the study of the different styles in the locus of control is relevant and, from the constructivist perspective, the study of the meanings and the analysis of the narrations of pain by the patients. The study of personality traits and their link with pain would be the most basic psychological approach. The study of coping styles would be in an intermediate place. Finally, the most elaborate approach would be the study of meanings.
It is interesting to make it clear that among the very different styles of coping with pain (avoidance, ignoring, reinterpreting, giving self-instructions, etc.), the most negative, the one that makes the pain worse, is the catastrophic style.
In the well-known constructivist perspective, authors such as Walker, Holloway, and Sofaer [53] studied five sequential themes in the experience of pain:
The pain takes hold of me
I lost something
I feel lost in the system
They do not understand me
My situation is unacceptable, inexplicable, speechless
In the psychosomatic field, stress has been a very studied element with respect to FM. When scales or questionnaires are applied, the stress scores in FM patients are higher than in the control groups. In addition, patients who score higher also show several psychological disorders. It has been postulated that chronic stress (but not acute stress) would contribute to the FM symptoms. It has also been noticed that specific situations of intense stress correlate with post-traumatic stress disorder and FM. Finally, among the patients with FM, a higher prevalence of experiences of victimization (abuse and sexual abuse), throughout the life, is detected. The intensity of the traumatic event correlates, in these cases, with pain and sleep disturbances.
Linked to this, it is worth noting the issue of social support, which is an issue usually over-mentioned by FM patients. Social support has three main functions:
Affective-emotional: intimacy, attachment, care, concern for the other, etc.
Material: provision of material assistance, assistance, etc., is an instrumental function.
Informative: advice, guide, education, etc.
The tendency to consider the first function as the most important is not correct. The key would be to give support based on the type of need that arises. Giving emotional support when the problem is strictly material, for example, may be tender, but it will not be effective. It must be noted that social support would lead to stress. Social relations imply obligations, and in turn, tensions can be derived from them. In short, stress can emerge. In fact, Helgeson [54], among others, points out that negative social interactions predict health- and well-being-related problems more than the positive ones do.
The differences between men and women in social support have not been studied much, although it is a simple fact that men and women differ in the way they participate in social relations. In this regard, it is necessary to mention something about gender roles. The traditional masculine role is associated with activity, the search for independence, competitiveness, objectives, assertiveness, self-confidence, etc., and within this role, it may be more difficult to seek and achieve social support. The role of women has been associated with expressiveness, emotions, intimacy, more ability to recognize difficulties (and with it to ask for help), cooperation, empathy, etc., thus giving and receiving social support seem to be easier tasks.
The association between social support, stress, and health has been studied without conclusive results due to serious methodological errors. Perhaps it would point out that the negative part of the social relations that we have already indicated is more relevant in the case of women. Why is it? Women tend to be a source of support more frequently and are more involved in socio-family networks. Belle already pointed out how support networks can create psychological distress: (a) for a lack of respect or disapproval of others; (b) for revealing confidences or not meeting the expectations of others; (c) when the support person is too demanding; and (d) when there is a sort of contagion of the stress from some members to others [55].
Beyond works with quantitative methodology, we will focus this section on qualitative research. This way of approaching knowledge is interpretive. It would be the interpretative study of a particular problem in which the researcher is responsible for the production of meaning. Many times, we reach statistically significant results that are absolutely useless, that do not discover anything, and that do not tell us anything that we did not know from our conversations with patients, and that, simply, we did not care to measure in order to know. In a different way, qualitative methods study intersubjective meanings located and constructed rather than supposed objective facts. Observation and interview would be prioritized over the experiment and the standardized questionnaires. In the understanding of the meanings, one works with the narrative, being storytelling a good tool for it. The laws of physical objects imply that there is no history, which is something impossible for the person. Faced with paradigmatic, objectivist thinking, without a position on itself, narrative thinking poses positions depending on the context. The data is not the central element, but where the data comes from, the person is the starting point, the private representation of the person about the world or its disorder, the way the person lives reality. The subject is therefore interesting: how the person builds the own context and makes history. The narrative is the element to reach that meaning sought. It is a story, a story ordered in some way. The narratives are unique, individual, unrepeatable, and have an author. They provide, finally, a meaning.
In order to research the experience of pain and its different repercussions in women diagnosed with FM, we performed individual in-depth interviews in a total of 15 patients. It is a semi-structured interview with some guide points but giving the patients the opportunity of a broad expression of their experiences. This way we tried to know the ideas that patients had about the disease but, above all, their experiences. The interviews lasted 50–60 min, were recorded in audio, and subsequently, transcribed with the collaboration of two psychologists. After the transcription, an analysis of the interviews was developed. For this purpose, in the clinical field, the methodology proposed by Weber for the analysis of content has been used [56]. It involves the following stages: (a) identifying common themes in the responses of patients and classifying them semantically, by their meaning; (b) grouping the themes of common meaning into categories; and (c) analyzing the frequency of each of the topics by watching its presence depending on the number of patients.
Our patients had a mean age of 45 years (ranged 36–59), all of them were women and married. Regarding their training level, 46.46% had primary studies (7 out of 15), and the rest were divided between degree or diploma (26.66%) and professional training or baccalaureate (26.66%). Besides, 40% were housewives (6 out of 15), and the rest worked in extra domestic tasks (26.66% as administrative assistants, 13.33% as operators, one of them as a secondary school teacher, another as clerk, and one as head of section in the regional administration). Those who had extra domestic works said that they had in charge the housework with some help from their couples. Eight of the patients had two sons and daughters and seven of them only one son or daughter. In three cases (20%), in addition to the couple and the children, other family members lived at home and they needed care.
As main concerns, patients referred the following:
The personal history of pain: time elapsed since the pain started, professionals consulted, treatments performed, time elapsed since the diagnosis of FM, biographical aspects at the onset of pain
The pain today: description (intensity, frequency, and duration) and treatment; what precipitates, worsens, or relieves
Thoughts regarding pain: what is attributed to, how to control it, what is thought when the pain appears
Feelings regarding pain: emotions that arise when facing pain
Behaviors as responses to pain: how the pain is faced
Repercussions of pain in daily life: functional impact on the patient (how pain limits life), impact on the family, social impact
Support against pain: what help do you have to deal with pain.
At this point, our focus was the personal history of pain. In this regard, it is worth noting some narratives of our patients:
Patient A: I was attended by several orthopedists and some of them gave me medication to the pain … the problem is that when one has … does not reach 30 years old and begins with continuous muscle contractures and without having a logical cause, well … even while playing sports in those moments, well, you get annoyed, don’t you? And then you go to one and the other, you even go to the neurosurgeon that the only thing he found was a minimal dehydration in … a … dorsal intervertebral disk … and … I think then it was progressively studied in case they found neck calcifications, they corrected them, they sent me to the rehabilitators…
Patient B: …It was mostly because of the birth of my daughter, well with … my daughter is already 10 years old, perhaps was the upbringing of the girl and also my father was diagnosed with a retinal detachment from the second eye because I had already had one and had lost the other eye … this brought me a lot of tension buildup…
Patient C: …When I was diagnosed with fibromyalgia I was suffering from pain for months, the pain started in the feet and hands, I had no strength in the hands, they became inflamed but I thought the housewives … I thought it was from the mop, scrub … always a blame for cleaning … I said to me “today I’m more tired of cleaning,” “today for…” …always blame until my husband told me to go to the doctor … he has the consultation in … and he made several medical checks, he gave me medications … until I went to another doctor who finally diagnosed fibromyalgia…
Patient D: …The first symptoms were that I complained about my legs and I was said I had a column deviation; when I was 25 it hurts me a lot … well with 25 … no, with 23, my neck started to hurt me a lot and doctors told me that it was a cervical problem and they gave me laser … well, I felt better, but pain remains, I always had pain and I continued with my medications … I was bearing pain, it was easy when I was 23, but now…
From a psychological point of view, topics such as “personality and fibromyalgia,” “emotional dysregulation,” and “fibromyalgia as a psychosomatic disease (labeled as negative connotations)” would be the most relevant aspects to deep into the patients’ thoughts, feelings, and behaviors.
FM is a disease with clear female predominance. Stress seems to be a highlighted element in its origin, especially chronic stress. Regarding social support, it is essential to mention that, in order to make it appropriate, the type of support (material, emotional, informative) must be in accordance with the needs that arise. Giving material support, when emotional support is necessary, is simply inefficient. We also said that social support can usually involve stress. Social relationships entail, for example, obligations from which tensions and stress may arise. It is also necessary to remember here that the traditional feminine role is associated with the expression of emotions and empathy.
In our patients we observe how they work mostly away from home, they bear the burden of homework, and in addition, one out of five not only takes care of their husbands and children but is in charge of some other relatives. And it is striking that 40% of these patients do not perceive any help to face their pain. They work inside, they work outside, they take care of everyone, they have pain, and they have no help. This is the reality of some women we interviewed. Chronic stress and FM? It does not seem to fit any doubt. And regarding the health of women, there is a chilling fact: patients usually take several drugs for more than 5 years, continuously, without a diagnosis of certainty. Some patients interviewed told us that the feeling that was seizing them on their pilgrimage from doctor to doctor was that they were labeled as hysterical or a merely storyteller and that they just told them to take a pain reliever when they had pain.
Some husbands, ratifying such clinical impressions, exclaim on more than one occasion: “Again, with your pain!” And since the traditional female role is designed to take care and not so much to receive care from others, to understand and not so much to be understood, in many cases it is hardly expected that, when a woman feels pain, the husband will give an adequate care. The trigger elements of pain are usually psychic tensions. There is nothing to add to it, chronic stress seems evident. Along with it there are thoughts of resignation not exempt of accompanying feelings of guilt. The random attribution of pain seems to be part of that female role of taking on loads (“this pain has also touched me!”). The feeling of guiltiness is strange. Facing pain limits the woman life, which prevents her to have a satisfying sex life, which keeps her at home, and which prevents her from performing her tasks. She feels guilty: guilty for not attending to her relatives and spoiling their vacations and guilty because she does not have sexual relations as often as she would wish and for not being able to enjoy them, for not having a clean house, etc. What makes her feel so guilty if it’s not the assumption of a traditional role? We leave the answer for your own reflection [57].
By the time patients get to the FM treatment program at different health institutions, they typically have tried all the approved drugs for the disorder and are tired of the pain, the fatigue, the depression, and the skepticism. Many patients have been told for years (by friends, by family, by clinicians) that their symptoms are imaginary or that they are lazy or drug-seeking.
Above and beyond the specific impact on health, from a social perspective, FM contemplates an impact at three levels: (a) family, (b) labor, and (c) about the health system.
In the family environment, patients point to the existence of family imbalances, putting at risk the maintenance and quality of their relationships in that context. It seems that there are at least four aspects to highlight:
A certain family disruption from the psycho-affective point of view (before or after the onset of the disease)
Family loads secondary to fibromyalgia (change of roles in family components, redistribution of tasks, loss of role, etc.)
Family economic losses
Patterns of family behavior directly related to fibromyalgia and its repercussions
In the work context, fibromyalgia is an important cause of work hour lost. In Spain, for example, people with fibromyalgia have an annual average of 21 days of work lost, and approximately one third of patients (depending on their jobs) already have a disability pension before they reach the retirement age (in other diseases this figure is around 9–10%). And, in summary, the percentage of temporary leave and the number of sick leave days is 3–4 times higher than in the case of other workers. In addition, it is known that the occupational impact of fibromyalgia seems to be strongly influenced by psychopathological comorbidity (especially anxiety and depression).
The impact on the health system refers to the amount of resources that these patients use, with the consequent economic cost. The positive part is arriving at a diagnosis as soon as possible, these costs decrease as it stops the pilgrimage of patients in search of evidence that clarifies their health problem. Patients with fibromyalgia visit the primary care physician at an average of 8–13 times a year, with almost €1,000 annual cost for such visits, about €500 for testing, and another €1,500 for “nonmedical” therapies (e.g., physiotherapy or massages). We must add about €500 per year for the use of different medications.
Storytelling, as an instrument of communication in health context, can be used to create a story as a way to share or receive information as well as a way for us to understand our own lives and those of others around us [58]. In this case, one of the signatories (MG) has composed a narrative to make fibromyalgia visible. Mya, the chief character of the play, wishes us to transmit the emotions and feelings of the people who bear patiently the illness. Sometimes, the lack of understanding or the disregard of those around them for the different aspect of their lives doesn’t help them to make progress. Various conditions affecting fibromyalgia patients have been depicted in this story. A great help for patients would be an overall consideration of clinicians, relatives, friends, and coworkers. Let us go to the story: and who is Mya (see Appendix 1)?
There is increasing recognition that multidisciplinary treatment models that address physical symptoms of the disease, as well as behavioral and psychological components, are effective, although total removal of symptoms is almost never achieved. The goal is improvement in health-related quality of life, function, and symptom burden. Patients should also know that symptoms will never kill them. The first step should be to address concerns, such as sleep or mood disorders. We are going to revise the different treatment options.
“Being on the hunt for the magic pill”: drugs don’t work very well with FM.
Antidepressants. The three main antidepressants that have been studied through controlled clinical trials in FM are [59, 60]:
Amitriptyline. It reduces pain and fatigue, improves sleep, and produces a global feeling of improvement from the perspective of both the doctor and the patient. It is therefore highly recommended.
Duloxetine. It also reduces pain and improves sleep and mood and quality of life and functional capacity, so it is also equally recommended.
Fluoxetine. Its evidence on pain, sleep, and fatigue in FM patients is controversial, and it seems to be effective for depressive symptoms and functional limitation. I would not currently be at the forefront of the recommendations of psychoactive drugs.
Gamma-aminobutyric acid (GABA) analog
Pregabalin. It was the first drug to be approved by the US FDA in 2007. Pregabalin reduces pain and improves sleep and quality of life, so it can be recommended for the treatment of these symptoms in patients with FM. It must be noted that a recent study comparing the efficacy of Duloxetine and Pregabalin concludes a higher efficacy of duloxetine for the treatment of pain in patients with FM [61].
Other pharmacotherapies, like opioids (e.g., tramadol), dopamine agonist (e.g., ropinirole, pramipexole, or rotigotine), cannabinoids (e.g., Nabilone), or sodium oxybate, do not seem to support its use for treating FM [62, 63, 64, 65].
Exercise. Exercise is known to be beneficial for overall health. Incorporation of some physical exercise with strengthening and stretching program as a part of FM treatment shows significant effects in reducing pain and related FM symptoms. Recent evidence suggests that exercise may regulate the immune- and stress-related responses [66, 67, 68].
Transcranial stimulation. Two types of noninvasive brain stimulation methods have been used to treat the cognitive and affective disorders [69]: transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). TMS sends a brief electrical current from an electromagnetic coil that is placed against the patient’s scalp, creating a regional magnetic field that affects neural activity. tDCS sends a weak electrical current through a pair of electrodes placed on the scalp in the region of interest. The current is considered to help modulate the neural activity, possibly in a polarity specific way [70, 71]. It appears that both TMS and tDCS may modulate mood, but the effects on pain may be marginal.
Psychological and behavioral modalities
Psychological treatment
There is great evidence of the effectiveness of cognitive behavioral therapy on pain control, physical discomfort, and mood in patients with FM [72]. Similarly, behavioral therapy has shown efficacy in reducing the number of medical visits.
Other treatments, such as relaxation techniques, used in isolation for the sole purpose of controlling pain, have not proven effective. On the other hand, despite some positive results, there is no scientific evidence to recommend hypnosis and other forms of therapy.
In any case, it seems that the best option is the use of “multicomponent therapies,” specifically those based on the combination of physical exercise, cognitive behavioral intervention strategies, and drugs. They have proven effective in managing pain and improving the quality of life and physical capacity of patients.
Alternative therapies
Today there is no scientific evidence on the effectiveness of certain treatments, at least for being recommended: acupuncture, homeopathy, ozone therapy, dietary supplements, Qi-Gong, Reiki, or Taichi [73].
Finally, the beneficial effect of chiropractic treatment and massage in the treatment of FM has not been sufficiently demonstrated, and therefore, its use is not recommended.
And who is Mya?
“El entusiasta”
The H.G. Wells Museum
Second day of the fatigue, Sunday. In the twenty-first century
News: and where’s Mya?
Yesterday, the Sculpture of Pain was stolen, a fifteenth-century masterpiece, highly valued by the Experts of Life. It belongs to the stage of the Spanish flamboyant gothic. It’s an alabaster sculpture made by Sebastián de la Esperanza. It symbolizes medieval culture; the accompanying book personifies Wisdom.
It was transferred in March 1999, from the Cathedral of Sigüenza to the recently opened H.G. Wells Museum.
The Commissioner of Righteousness has asked to cooperate with the country’s officials to investigate the clues in depth.
This morning, the main authorities of the emotions, have established the action plan and the resources they will provide to clarify the events that occurred.
At the moment, the museum officials have not made authorized statements. At 7:30 pm, the director called a press conference at the headquarters of the feelings (25 Transcendence St.), to make the first manifestations of what happened.
A reward is offered to all those who care about visibility.
Myalgia
Mya reads the news and decides to go to the museum. She cannot accept another day of tiredness and fatigue.
The H.G. Wells Museum is a building without defined forms. A weird-speaking drone with fraudulent voice announces: “free admission.” There is a large uneven corridor where three rooms are placed on the right side and one more on the left.
What do they hide?
Mya enters into the first of the rooms in the right: “The Room of the White Coats.” Although Painting One greets her kindly, it can only spend 5 minutes because there are too many visitors. It examines her quickly and recommends talking to Painting Two. Then, the latter gives her some futuristic capsules and asks her to come back at another time. Finally, a whisper leads her to Painting three, which tells her that it has something for pain. It scares her because she hadn’t explained anything.
She comes out very confused, and stays absorbed in the middle of “The Family Room,” right next to the caution tape that the Art Police had put to cordon off the scene. She hears peaceful voices. Being suspended in the air, the legless chairs tell her that they are almost no longer visited or accompanied. At the beginning of the opening of the museum, it was the most frequented room, but now they are not important to them or simply do not know how to look at them. On the ceiling of this lugubrious room there is a Deco Lamp that looks at the walls with the complicity of the years. From a distance it seems to say: “I already knew that sooner or later it would happen.” The always silent Deco Lamp addresses the intrigued Mya sharing its thoughts: “They have never watched us, they don\'t care, people come and go, they look at us but they don\'t see us. They extract what we have inside but they give us nothing back. The one who hung us performed his function. The one who repairs us, from time to time, also believes that he has fulfilled his duty. But now, that doesn\'t care.” And the Sculpture of Pain was she left to her fate by a wrong way or did she abandon her privileged place in the museum because of misunderstanding and loneliness?
Curiosity leads her to the “Just in Time Room,” where the Mosaics are in continuous synchronized motion and almost silent. They ignore her. They prefer not to have eye contact with her. They have lost the habit. They do not recognize visitors because they are missing too much. Their complaints and regrets bore them. They don’t feel they are part of the team.
Once she visited the rooms on the right of the corridor, she went to the left side, to the “Not Near Room.” Those who were next to the stolen sculpture. And since their disappearance they have not even asked again. Sculptures with no eyes look her up and down, without any empathy. She prefers to think they have not seen her. She listens to a secure voice, which comes from the Spokesman of the Council of Emotions, who starts the meeting. It is necessary to face the fact of theft and start making decisions. Find out who has been the guilty before it is judged by the Court of Righteousness.
After 5 hours, the members of the council were still trying to assess what could have happened with the sculpture. The clues confused them. The Query Painting had not manifested yet. Its strokes made a slight movement. Everyone else looked paying more attention than on other occasions, but they didn’t understand why the picture wasn’t able to talk.
Mya, as she did not know anything about it, felt a greater curiosity for the painting. She waited just to see what it was doing. Its images were as clocks with distorted shapes and its light was different from the rest. Would it know who was the guilty of the disappearance? What were the reasons of its differences? Would it be able to reach others with harmony? What a different museum! All its elements express those they feel and hear! She exclaimed.
Suddenly, several coordinated voices arise:
Painting Two: “We were drawn to remember the decay of those who live depending on something or someone.”
Sculpture Eight: “We were built to remember that principles exist.”
Mosaic Fifteen: “We were just to remember that the senses exist.”
Frame Ten: “We were to remember the transcendence.”
Everyone directed their forms to Painting Seven, which looked at the ground for a few seconds and shouted with no-voice: “Please, let’s change something about our past!”
From this moment on, they understood why the Pain with their Sculpture had decided to leave.

This book serves as a comprehensive survey of the impact of vitamin K2 on cellular functions and organ systems, indicating that vitamin K2 plays an important role in the differentiation/preservation of various cell phenotypes and as a stimulator and/or mediator of interorgan cross talk. Vitamin K2 binds to the transcription factor SXR/PXR, thus acting like a hormone (very much in the same manner as vitamin A and vitamin D). Therefore, vitamin K2 affects a multitude of organ systems, and it is reckoned to be one positive factor in bringing about "longevity" to the human body, e.g., supporting the functions/health of different organ systems, as well as correcting the functioning or even "curing" ailments striking several organs in our body.
