Silicone breast implant–associated musculoskeletal manifestations

Abstract:

Three hundred consecutive women with silicone breast implants (SBI), referred to the arthritis clinic with a variety of musculoskeletal complaints, were evaluated for the presence of underlying connective tissue disease. A complete history and physical examination were performed, as well as laboratory testing for C-reactive protein, rheumatoid factor; and autoantibody determination by indirect immunofluorescence and immunodiffusion.

The group mean age was 44.4 years (range 25-69), the mean time from initial implant surgery to appearance of symptoms was 6.8 years (range: 6m-19y) and 83.3% of women studied had clinical manifestations highly suggestive of an underlying connective tissue disorder. Fifty-four percent met criteria for fibromyalgia and/or chronic fatigue syndrome, distinct connective tissue diseases was detected in 11%, undifferentiated connective tissue disease or human adjuvant disease was found in 10.6%, and a variety of disorders such as angioneurotic oedema, frozen shoulder, multiple sclerosis-like syndrome were present.

Several other miscellaneous conditions including recurrent unexplained low grade fever, hair loss, skin rash, sicca symptoms, Raynaud’s phenomenon, carpal tunnel syndrome, memory loss, headaches, chest pain, and shortness of breath were also seen accompanying specific and non-specific conditions. Seventy percent of patients who underwent explanation of the implants reported improvement of their systemic symptomatology.

A significant proportion of SBI patients referred for rheumatic evaluation have clinical manifestations highly suggestive of an underlying connective tissue disease. Furthermore, improvement of their symptomatology follows explanation of the implants in over half of the patients.

The pathogenesis of chronic pain and fatigue syndromes, with special reference to fibromyalgia

Abstract:

Syndromes characterized by chronic pain and fatigue have been described in the medical literature for centuries. Fibromyalgia is the term currently used to describe this symptom complex, and considerable research has been performed in the last decade to delineate the epidemiology, pathophysiology, and genesis of this entity. Although fibromyalgia is defined by its musculoskeletal features, it is clear that there are a large number of non-musculoskeletal symptoms, such that we now understand that there is considerable overlap with allied conditions such as the chronic fatigue syndrome, migraine and tension headaches, irritable bowel syndrome, and affective disorders. This article will review our current state of knowledge regarding fibromyalgia and these allied conditions, and present a unifying hypothesis that describes both the pathophysiology of symptoms and the genesis of these disorders.

Absence of parvovirus B19 infection in chronic fatigue syndrome

Abstract:

OBJECTIVE: To evaluate the presence of infection with parvovirus B19 in patients with chronic fatigue syndrome (CFS) who also had rheumatologic symptoms and mild hematologic abnormalities.

METHODS: Seven patients meeting the Centers for Disease Control and Prevention working case definition for CFS who also had mild leukopenia, thrombocytopenia, or anemia were studied. Bone marrow was aspirated from each patient, and examined for morphologic abnormalities, including features seen in marrow infections with parvovirus B19, as well as for parvoviral DNA, using polymerase chain reaction (PCR) amplification. Serum obtained at the time of marrow aspiration was also evaluated for parvoviral DNA, using the PCR method, and was examined for the presence of IgM and IgG antibodies to the virus.

RESULTS: No evidence of marrow involvement with parvovirus B19 was found in any patient. One patient had antibody evidence of a transient parvoviral infection, during which time an underlying thrombocytopenia worsened.

CONCLUSION: Despite examining a selected group of patients thought most likely to have parvoviral infection, based on clinical and hematologic measures, no evidence of clinically important parvoviral infection was noted. Thus, it seems unlikely that parvovirus B19 plays a role in CFS, even though it has been associated with fibromyalgia, a clinically similar syndrome.

Fibromyalgia, chronic fatigue syndrome, and myofascial pain syndrome

Abstract:

Two important studies in which nuclear magnetic resonance spectroscopy was used convincingly demonstrated that muscle is not the primary pathologic factor in fibromyalgia. There were further studies reporting that fibromyalgia-chronic fatigue syndrome may follow well treated Lyme disease or mimic Lyme disease. The longest therapeutic trial to date in fibromyalgia demonstrated an initial modest effect of tricyclic medications, but at 6 months that efficacy was no longer evident. Investigation in both fibromyalgia and chronic fatigue syndrome now focuses on the central nervous system. The use of new technology, eg, neurohormonal assays and imaging such as single-photon emission computed tomography scan, may be important in understanding these elusive conditions.

Sleep, neuroimmune and neuroendocrine functions in fibromyalgia and chronic fatigue syndrome

Abstract:

The justification for disordered chronobiology for fibromyalgia and chronic fatigue syndrome (CFS) is based on the following evidence: The studies on disordered sleep physiology and the symptoms of fibromyalgia and CFS; the experimental studies that draw a link between interleukin-1 (IL-1), immune-neuroendocrine-thermal systems and the sleep-wake cycle; studies and preliminary data of the inter-relationships of sleep-wakefulness, IL-1, and aspects of peripheral immune and neuroendocrine functions in healthy men and in women during differing phases of the menstrual cycle; and the observations of alterations in the immune-neuroendocrine functions of patients with fibromyalgia and CFS (Moldofsky, 1993b, d). Time series analyses of measures of the circadian pattern of the sleep-wake behavioural system, immune, neuroendocrine and temperature functions in patients with fibromyalgia and CFS should determine whether alterations of aspects of the neuro-immune-endocrine systems that accompany disordered sleep physiology result in nonrestorative sleep, pain, fatigue, cognitive and mood symptoms in patients with fibromyalgia and CFS.

Comparison of patients with chronic fatigue syndrome, fibromyalgia, and multiple chemical sensitivities

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS), fibromyalgia (FM), and multiple chemical sensitivities (MCS) are conditions associated with fatigue and a variety of other symptoms that appear to share many clinical and demographic features. Our objectives were to describe the similarities and differences among patients with CFS, FM, and MCS. Additional objectives were to determine how frequently patients with MCS and FM met the criteria for CFS and if they differed in their health locus of control.

METHODS: Demographic, clinical, and psychosocial measures were prospectively collected in 90 patients, 30 each with CFS, FM, and MCS. Patients were recruited from a university-based referral clinic devoted to the evaluation and treatment of chronic fatigue and three private practices. Variables included demographic features, symptoms characteristic of each condition, psychological complaints, a measure of health locus of control, and information on health care use.

RESULTS: Overall, the three patient groups were remarkably similar in demographic characteristics and the presence of specific symptoms. Patients with CFS and FM frequently reported symptoms compatible with MCS. Likewise, 70% of patients with FM and 30% of those with MCS met the criteria for CFS. Health care use was substantial among patients with CFS, FM, and MCS, with an average of 22.1, 39.7, and 23.3 visits, respectively, to a medical provider during the prior year. Health locus of control did not differ among the three populations.

CONCLUSIONS: In general, demographic and clinical factors and health locus of control do not clearly distinguish patients with CFS, FM, and MCS. Symptoms typical of each disorder are prevalent in the other two conditions.

Stealth viruses as neuropathogens

Abstract:

Neuropsychiatric diseases viewed as multifaceted expression of a dysfunctional brain in which atypical responses are evoked by various sensory inputs. Disease entities have traditionally been classified according to the predominant manifestation ( ) without regard to the overlapping features of many of the diseases (+/-). Thus, mild to moderate pain, mood, cognitive, and neurosomatic symptoms are frequently present in chronic fatigue syndrome (CFS) patients. Fibromyalgia syndrome (FMS) is listed as an example of a predominantly chronic pain syndrome. Affect (mood) disorders include depression (Depress.), anxiety, panic reactions, blunted affect, mania, etc. Schizophrenia (Schizo.) is listed as an example of a major cognitive psychosis. Autism as well as various forms of dementia would be included in this category. Irritable bowel syndrome (IBS) is an example of a neurosomatic disease.

Human adjuvant disease revisited: a review of eleven post-augmentation mammoplasty patients

Abstract:

OBJECTIVES: We have reviewed 11 women post-augmentation  who were referred to our clinic with diffuse rheumatic complaints. All patients had undergone mammoplasty with silicone gel-filled implants prior to the onset of their locomotor symptoms (mean latency time 7.8 years). One physician interviewed and examined each of these patients following a standardized format for clinical retrieval.

RESULTS: Of the patients reviewed, 6 patients had clinical fibromyalgia based on the ACR criteria, and the remaining 5 patients had symptoms consistent with the “chronic fatigue syndrome.” None of our patients were found to have evidence of a defined connective tissue disease. Antinuclear antibodies were detected in 4 (36%) patients and low level titres of extractable nuclear antigens in only 2 (18%).

CONCLUSIONS: Previously a causal relationship between the use of silicone gel-filled breast implants and the subsequent development of symptoms referred to as human adjuvant disease (HAD) has been proposed. On the basis of currently accepted criteria we have preferred to diagnose our post-mammoplasty patients without specific connective tissue disease, as having chronic fatigue syndrome (CFS), or when tender points are present, as having fibromyalgia (FMS), rather than implying that such cases represent a separate and unique rheumatological disease entity. In the light of our current understanding of CFS and FMS, a relationship between them and the previous silicone mammoplasty seems possible.

Gender differences in patients with chronic fatigue syndrome

Abstract:

OBJECTIVE: To determine whether there are differences between men and women patients who have chronic fatigue syndrome (CFS) and, if so, to ascertain whether a gender-related pattern exists.

DESIGN: A descriptive study of demographic, clinical, and psychosocial measures, the results of which were prospectively collected for patients who had CFS.

SETTING: A university-based referral clinic devoted to the evaluation and management of chronic fatigue.

PATIENTS: 348 CFS patients who had undergone complete medical evaluations.

MEASURES: Clinical variables included symptoms, physical examination findings, and laboratory results. Psychosocial assessment consisted of a structured psychiatric interview, the Medical Outcomes Study Short-form General Health Survey to assess functional status, the General Health Questionnaire to ascertain psychological distress, the Multidimensional Health Locus of Control, and measures of attribution, social support, and coping.

MAIN RESULTS: Overall, few gender-related differences were identified. Women had a higher frequency of tender or enlarged lymph nodes (60% versus 33%, p < or = 0.01) and fibromyalgia (36% versus 12%, p < or = 0.001) and lower scores on the physical functioning subscale of the Medical Outcomes Study Short-form General Health Survey (37.6 versus 52.2, p < 0.01); men more often had pharyngeal inflammation (42% versus 22%, p < or = 0.001) and reported a higher lifetime prevalence of alcoholism (20% versus 9%, p < or = 0.01).

CONCLUSIONS: In general, demographic, clinical, and psychosocial factors do not distinguish men from women CFS patients.

Pain rehabilitation. 2. Chronic pain syndrome and myofascial pain

Abstract:

This article highlights chronic pain syndrome and myofascial pain. It is part of the chapter on pain rehabilitation in the Self-Directed Medical Knowledge Program for practitioners and trainees in physical medicine and rehabilitation. This article discusses behavioral maladaptations to chronic pain which lead to global physical, psychologic, social, and vocational impairments–the chronic pain syndrome. The spectrum of myofascial pain syndromes, contributing factors, and interventions are detailed. New advances that are covered in this section include controversies in long-term use of opioids and muscle relaxants; differentiating fibromyalgia, myofascial pain syndromes, and chronic fatigue syndrome; pathophysiology of myofascial pain; and beneficial treatments.
