This review summarizes the symptoms, signs and laboratory abnormalities seen in 59 patients with chronic fatigue syndrome (CFS), 2 patients with post-infectious CFS and in 26 patients with possible CFS whose illnesses fulfill the criteria proposed by the study group of the Ministry of Welfare, Japan. The characteristic symptoms and signs of CFS are prolonged generalized fatigue following exercise, headache, neuropsychological symptoms, sleep disturbance and mild fever. In possible CFS patients, the frequency of mild fever, muscle weakness, myalgia and headache is low. Our standard hematologic and laboratory tests revealed a few abnormality in patients with CFS. The characteristic abnormality in CFS patients is the low values of 17-Ketosteroid-Sulfates/creatinine in morning urine and the acylcarnitine deficiency. It seems likely that this deficiency of acylcarnitine induces an energy deficit in the skeletal muscle, resulting in general fatigue, myalgia, muscle weakness and postexertional malaise in CFS patients. Virologic studies revealed no evidence of retrovirus infection with HTLV-1, HTLV-2 and HIV, but the reactivation of HHV-6 infection was apparent.

In 11 patients, all women, 21-55 years of age, with unilateral work-related myalgia of the trapezius muscle, the right and left trapezius muscles were examined simultaneously for electromyogram (EMG) signs of localized muscle fatigue. All patients were tested with 0-kg hand load for 5 min, holding the arms straight at 90 degrees of elevation in the scapular plane. Only 4 of the patients tolerated exposure to higher load levels. They were tested with 1 kg hand load for 3 min and 2 kg hand load for 2 min, with a period of rest of 30 min between the trials. The EMG mean power frequency (MPF) and root mean square (rms) were calculated. Data were normalized with the initial value as a reference and regression analyses were performed. On both sides a decrease of MPF and an increase of rms were found with increasing time and load, i.e. classical EMG signs of localized muscle fatigue. Compared with the nonaffected side smaller changes were found on the affected side, possibly due to pain inhibition, impaired microcirculation and biochemical changes along the muscle fibres. At 0-kg hand load we found no change of MPF on either side despite subjective feelings of fatigue and pain. We interpreted these findings as an indication of reduced capacity of the affected trapezius muscle to sustain static load with early development of pain-associated local fatigue.

Patients with erythema multiforme (EM) often have chronic or recurring oral lesions that cause intense pain and interfere with a variety of functions including eating and speech. Previous studies suggest that levamisole restores to normal the function of phagocytes and T lymphocytes, and activates the inflammatory response. In our previous double-blind study 8 of 13 patients with EM had a decrease in severity and frequency of attacks. The purpose of this open prospective study was to evaluate short-term and long-term clinical efficacy of levamisole in patients with mucocutaneous EM. Thirty-nine patients with mucocutaneous EM seen in the Oral Medicine Clinic, School of Dentistry, University of California-San Francisco, comprised our study group. Levamisole was used alone in 17 patients or in combination with prednisone in 22 patients and was given as a single dose of 150 mg/day for 3 consecutive days. Thirty-one patients showed a complete response from levamisole (alone in 13 and in combination with prednisone in 18). Four showed a partial response of signs and symptoms, and four others had no benefits from levamisole whether alone or in combination. The most common side effects from levamisole were skin rash, tiredness, weakness, myalgia, taste change, and insomnia.

Fourteen children (ages 2-15 years) with acute leukemia in relapse were treated with daily recombinant interferon gamma for 14 days by subcutaneous injections at fixed dose levels of 0.1, 0.25, 0.5, or 0.75 mg/m2 (1.0, 2.5, 5.0, or 7.5 x 10(6) units/m2) without intrapatient escalation. Patients received a second 14-day course of therapy followed by thrice weekly administration unless there were signs of progressive disease or grade 3 or 4 toxicity. Side effects in the 13 evaluable patients included fever (n = 10), fatigue (9), decreased Karnofsky performance score (8), hypertriglyceridemia (8), myalgia (5), weight loss > 5% (4), elevated liver transaminases (4), and abdominal pain (3). There was only one grade 4 toxicity: one of the six patients at the 0.5 mg/m2 dose level developed reversible acute renal failure. One patient died of gastrointestinal hemorrhage due to disease-related refractory thrombocytopenia. One child had an oncolytic response and two others stable disease for 138 and 148 days. An appropriate dose level for phase II studies in children is 0.5 mg/m2 per day.

A late-onset syndrome, consisting of muscle weakness, muscle pain, and unaccustomed fatigue, has been reported with increasing frequency among former poliomyelitis patients. A population-based cohort of poliomyelitis patients from Allegheny County, Pennsylvania, was traced and surveyed to estimate the prevalence and incidence and to identify determinants of the post-polio syndrome. A questionnaire validated in clinical examinations of 40 cohort members was used in the survey. The prevalence of the post-polio syndrome was 28.5% of all paralytic cases (95% confidence interval 24.4-32.6). The risk of post-polio syndrome was significantly higher among patients who sustained substantial permanent impairment after polio and among females. The incidence did not vary with age at acute onset, acute severity, or level of physical activity after recovery. The strongest determinant of post-polio syndrome onset was the length of the interval following the acute illness, with incidence peaking at 30-34 years. Of all cases of post-polio syndrome, 79% reported no major change in impairment status since onset. This study demonstrates that poliomyelitis patients are not equally susceptible to post-polio syndrome within the interval of 30-40 years after the original illness. For syndrome cases, the onset was associated with new neuromuscular symptoms and functional changes but not with major new impairment.

Abrupt or gradual discontinuation of tricyclic antidepressants may precipitate withdrawal symptoms. The most common of these are general somatic or gastrointestinal distress, anxiety and agitation, sleep disturbance, akathisia, parkinsonism, paradoxical behavioral activation and mania. There are very few reports of withdrawal reactions following discontinuation of clomipramine since it has not been in use in the US until recently. 2 patients with withdrawal symptoms following discontinuation of clomipramine are presented. A 45-year-old man had general somatic symptoms, including headache, myalgia, weakness, fatigue (flu-like syndrome) and nervousness and insomnia after clomipramine, 75 mg/d, had been discontinued abruptly. All symptoms disappeared without treatment after 3 days. A 47-year-old woman presented mainly with severe insomnia, anxiety, agitation, jitteriness and tension after discontinuing a low dose of 25 mg/d of clomipramine. Symptoms disappeared after she started self-treatment with 50 mg/d of the drug. It is important to differentiate withdrawal symptoms from relapse of the primary psychiatric disorder.

A severe foodborne outbreak of group A streptococcal disease (T28) affected 122/169 people (72%) who attended a church party or ate leftovers from the party. The median incubation time was 42 h. Muscular pain or weakness and fatigue usually preceded pharyngeal symptoms. Complications included otitis media with perforation, peritonsillitis requiring tonsillectomy, arthritis and pericarditis. A 45-year-old man died 36 h after he developed an influenza-like illness, and at necropsy there were histological signs of early streptococcal septicaemia. The strain produced erythrogenic exotoxins B and C. Streptococci were probably transmitted by sliced eggs on sandwiches. Laboratory experiments showed that there was an increment in viable count of streptococci with 6 logs after incubation in egg yolk for 24 h at room temperature. The unusually warm climate and flaws in food handling routines contributed to this large foodborne epidemic.

We report here the long-term sequelae in 22 patients with L-tryptophan-induced eosinophilia-myalgia syndrome (EMS). The mean follow-up was 23 months (range, 5 to 40 months). Myalgia, rash, pruritus, edema, and respiratory symptoms often improved with the use of corticosteroids, but fatigue and weakness persisted in most cases. Other abnormalities that commonly persisted were arthralgia, muscle-cramping, peripheral neuropathy, and thickened skin. One patient had chronic pulmonary hypertension. These findings indicate that for most patients, EMS is a chronic disorder.

Twenty-one patients with metastatic prostate cancer who had become refractory to hormonal therapies received lonidamine (150 mg tid and 600 mg daily dose in 17 and 4 patients, respectively). In all but 4 patients, treatment was continued until disease progression or the development of severe toxicity. Toxicity was minimal and reversible (score 1 or 2) and included myalgia (8 cases), arthralgia (6 cases), gastrointestinal toxicity (11 cases), fatigue (14 cases) and testicular pain (9 cases). The response was evaluated after at least one month of therapy with lonidamine, according to NPCP-USA recommendations. Of 21 patients who entered the study, only 15 were evaluable for response; 2 died (1 for severe toxicity and 1 for drug-unrelated reasons). No objective response was obtained in the series. In fact, only 6 patients achieved stable disease and 9 progressed. Median survival time from the beginning of treatment was no longer than that of patients in a similar condition who were treated with standard palliative maneuvers. We conclude that this therapeutic approach with lonidamine is not active in hormone-refractory prostatic cancer patients with distant metastasis.

We describe the histopathologic changes of skin, muscle, vessels, and fascia in 11 patients with eosinophilia myalgia syndrome, a newly described entity that has been linked to the ingestion of L-tryptophan. This syndrome is defined clinically by severe incapacitating myalgias and a peripheral eosinophilia. Arthralgias, edema of the extremities, morbilliform rashes, skin induration, weakness, fatigue, and respiratory weakness may be present as well. The earliest apparent histologic changes were observed at the septa between subcutaneous fat lobules and in the deep dermis or fascia. The septa and fascia were infiltrated with a sparse mixture of lymphocytes and histiocytes. In the deep fascia, in addition to inflammatory cells, there were distinctive, reactive mesenchymal cells that showed features of both histiocytes and fibrocytes. Minimal tissue eosinophilia was seen despite the extent of blood eosinophilia. Dermal thickening and homogenization of collagen bundles occurred with replacement of fat and adnexa (changes indistinguishable from scleroderma or morphea). Vessel walls in the dermis and fascia showed thickening and endothelial swelling, but no overt vasculitis was noted. Skeletal muscle biopsies showed a perimysial, epimysial, and/or fascial inflammatory infiltrate of lymphocytes and distinctive reactive mesenchymal cells with some eosinophils. Minimal myofiber atrophy, regeneration, or necrosis was seen despite the clinical history of severe myalgias in almost all patients. This syndrome should help gain insight into the mechanisms of fibrosis in environmental-induced, scleroderma-like syndromes and in idiopathic, scleroderma-like disorders as well.
