A case of the nodular form of polymyositis is reported in which muscle necrosis and inflammation, and fibrosis of subcutaneous fat were observed. Although the patient had a short history, the presence of extensive fibrosis with acute lesions indicated that the disease had been present for some time. In addition to the nodular lesions, the patient had clinical, electrophysiological and pathological evidence of a more generalised myopathy. The subsequent development of a rash resembling that of vasculitis and a peripheral nerve lesion, suggested that the localised nodular myositis was associated with systemic vasculitis. Although immunoglobulin and complement deposits were not detected in blood vessel walls in muscle or skin, a positive reaction to intradermal injection of autologous serum suggested the presence of circulating immune complexes.

In nearly 60% of men over 50 years of age, dermato-/polymyositis is induced by malignancies. Till now, 9 patients with melanoma-induced dermatomyositis have been reported in the literature. Here we report on a patient suffering from classic pelvic and pectoral girdle proximal weakness, typical heliotrope rash, increased serum CPK values, and biopsy-proven myositis, who died from metastasizing melanoma one year later.

This is the first report of a child with anti-Jo-1 antibody. At 10, she had a chronic cough, wheezing, dyspnea on exertion, a combined obstructive and restrictive ventilatory defect, and a decreased diffusion capacity compatible with alveolar fibrosis (lung biopsy). By age 12, she developed arthralgias, malar rash, frontal alopecia, Raynaud's phenomenon, and was seropositive for antinuclear antibodies, (SSA)Ro, Jo-1 and rheumatoid factor. At 16, symptomatic inflammatory myositis (elevated creatinine kinase, muscle biopsy) was documented with persistent anti-Jo-1. Her pulmonary symptoms have progressed despite appropriate therapy. Although her digits have become sausage shaped with swan neck deformities, joint pain is not frequent.

Demonstration of myositis in juvenile dermatomyositis (JDM) has traditionally required the presence of two out of three objective findings including muscle enzyme studies, electromyography, and muscle biopsy. Magnetic resonance imaging (MRI) is considered another objective criterion and has been recommended for follow-up studies as well. We report on a 6-year-old girl with JDM, presenting with facial rash and proximal muscle weakness, in whom MRI, in conjunction with elevated creatinine kinase (CK) levels, was diagnostic, with an increased T2 signal of proximal muscles. MRI reflected exacerbation of myositis in spite of steroid therapy 2 weeks later, but failed to mirror normalization of muscle strength and CK values 10 weeks later. In fact, improvement of MRI followed clinical and laboratory normalization with a delay of 2 months. This possible delay should be considered when MRI is used to monitor the response to therapy.

Among the main concerns regarding the current therapy for the inflammatory myopathies are a lack of adequate controlled trials, a lack of objective means to reliably measure muscle strength, lack of natural history data, consideration of polymyositis, dermatomyositis, and inclusion-body myositis as a homogeneous group of inflammatory myopathies, and reliance on nonspecific markers for determining prognosis and assessing response to therapies. Prednisone remains the drug of choice in treating these disorders, although a controlled trial has never been undertaken to study its efficacy. Among the steroid-sparing agents, azathioprine, methotrexate, cyclosporine, and chlorambucil are used with invariably low to moderate success. There are no results of controlled trials to indicate whether one of these drugs is superior to another. Intravenous immunoglobulin, which is very expensive, was shown in a controlled trial to be effective in steroid-resistant dermatomyositis not only in dramatically improving muscle strength and skin rash but also in resolving the underlying immunopathology. Controlled trials of intravenous immunoglobulin in patients with polymyositis and inclusion-body myositis are under way. Inclusion-body myositis has emerged as a common inflammatory myopathy that is predictably disabling and resistant to most therapies.

During a four-week trip to Nigeria a 54-year-old German developed a fever of 39 degrees C. Later on he had lymphadenopathy, pretibial oedema, dyspnoea and weight loss. After 16 weeks a wreath-like pale pink skin rash, increased pulse rate with pulse deficit and hepatosplenomegaly were noted. Abnormal laboratory findings were an increased blood sedimentation rate (95 mm), raised immunoglobulin M (483 mg/dl), haemoglobin of 12.0 g/dl, mean corpuscular volume of 76 fl and Borrelia IgM antibody titre of 1:512. The electrocardiogram was suggestive of myocarditis: the cardiac symptoms were controlled with digoxin and verapamil. The patient's general condition deteriorated while he was receiving antibiotic treatment with tetracycline and penicillin. Cerebrospinal fluid (CSF) showed an increased cell count (39/microliters) and albumin (0.98 g/dl). There was a mild, predominantly proximal, tetraplegia which--on the basis of electromyographic and biopsy findings--was thought to be due to polyneuritis and myositis. At this stage blood smear and CSF examination revealed Trypanosoma. He thereupon received suramin (1.0 g) and prednisolone (120 mg down to 40 mg) daily, to which melarsoprol was added after 6 days (0.5 ml up to 5.0 ml daily for 36 days). Almost all symptoms then regressed within 6 weeks.

BACKGROUND. Dengue is an acute febrile illness caused by several arthropod-born viruses and characterized by biphasic fever, myalgia or arthralgia, rash, leukopenia and lymphadenopathy. Its diagnosis is based on knowledge of the geographic distribution of dengue viruses. CASE REPORTS Case no 1: A 11 year-old boy suffered from sudden onset of fever accompanied by retro-orbital headache, arthralgia and diffuse myalgia. There was no rash. Hemogram showed: hemoglobin: 11.6 g%; leukocytes: 3,400/mm3 (PMN: 76%); platelets: 190,000/mm3. A diagnosis of viral infection was considered, but, as the boy had recently been to the French West-Indies, a serologic study was performed. This was negative 2 days after the onset of disease and positive (specific IgM for the 4 dengue types), 13 days later. Case no 2: A 7 year-old boy suffered from sudden onset of fever. Severe calf muscle pain 4 days later led to his admission. Creatine phosphokinase activity was very high: 83,100 units (N: 30-120). Hemogram showed: hemoglobin: 11.4 g%; leukocytes: 2,500/mm3 (PMN: 60%); platelets: 124,000/mm3. A diagnosis of acute myositis was considered, but as the patient had recently visited Venezuela, a serologic study was performed. This was negative 8 days after the onset of disease and positive (specific IgM for the 4 dengue types) 16 days later. CONCLUSION. The first case is characteristic of the classical form of dengue fever. The second patient presented with very localized myalgia. The diagnosis in both cases was facilitated by the knowledge that the patient had recently stayed in an endemic area.

A double-blind, randomized study was undertaken to evaluate the efficacy and safety of fluvastatin as monotherapy and as combination therapy with niacin in the treatment of hypercholesterolemia refractory to diet. Seventy-four patients with plasma low-density lipoprotein cholesterol (LDL-C) levels > or = 160 mg/dL were treated with fluvastatin, 20 mg/d, or placebo for 6 weeks. Thereafter, immediate-release niacin, at a dosage titrated to a maximum of 3 g/d, was added to both regimens for another 9 weeks. All adverse events were monitored, with particular attention to the evaluation of liver and muscle enzymes. Initial analysis of the data shows that fluvastatin and its combination with niacin was well tolerated and was not associated with any serious adverse events. Small, transient, asymptomatic rises in aspartate aminotransferase (AST) occurred in 28.9% of fluvastatin-niacin treated patients compared to 8.3% in the niacin-placebo control arm (p < 0.05). These were considered clinically insignificant in that no transaminase elevations > 3 times the upper limit of normal occurred. No evidence of myopathy, creatine kinase levels exceeding 10 times the upper limit of normal, myositis, or rhabdomyolysis were demonstrated in this short-term trial. The majority of adverse events resulting in patient withdrawals were ascribed to niacin therapy and included cutaneous vasodilatation, flushing, itching, and rash. These preliminary results suggest that fluvastatin, both alone and combined with niacin, is an effective, safe, and well-tolerated treatment for hypercholesterolemia.

Some patients of dermatomyositis (DM) with interstitial pneumonia (IP) have common clinical features. Clinical features of these patients are acute onset, very poor prognosis and that patients have fever, arthritis, typical skin rash, mild myositis and show low ratio of CPK/LDH, low incidence of antinuclear antibody (ANA) appearance, low inflammatory signs. We experienced two cases of this category of DM with IP and examined immunological aspects. Case 1. A 52-year-old woman was admitted in June 1, 1990 with a one-month history of arthralgia and a ten-days history of fever, skin rash, myalgia and dyspnea on exertion. On examination she had Gottron's papules on her fingers, erythema on back, bilateral elbows and legs, proximal muscle weakness and arthritis. Fine crackles were audible in the lower lung fields. Laboratory data included CPK 200 IU/l, ALD 3.2 IU/l, LDH 805 IU/l. Analysis of bronchoalveolar lavage fluid (BALF) revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid (CS), pulse CS, cyclosporin A. Inspite of these therapies, she died of progressive respiratory insufficiency in July 10, 1990. Case 2. A 23-year-old woman was admitted in April 1, 1991, with a two-month history of arthralgia and a one-month history of fever, skin rash, stomatitis, alopecia. On examination she had Gottron's papules on her fingers, erythema on malar, bilateral elbows and legs, arthritis and stomatitis. Laboratory data included CPK 97 IU/l, ALD 8.5 IU/l, LDH 779 IU/l. She began experiencing dry cough and dyspnea on exertion in May 1991. Analysis of BALF revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid(CS), pulse CS, pulse cyclophosphamide.(ABSTRACT TRUNCATED AT 250 WORDS)
