A case of polymyositis in a 15 year old girl demonstrating the clinical course of an infectious disease is presented. The Coxsackie virus B2 was isolated from the stools, and serum antibodies were detected. Histologic examination of muscle showed signs of myositis. The patient was treated with cortisone and recovered completely. Possible viral etiology of the polymyositis is suggested.

Fifty patients were hospitalised at Vientiane during May and June 1975. Infection was caused by consumption of pork meat (som-mou, lap mou and lap leuat). After an incubation period of 8 to 11 days intermittent diarrhoea followed by constant fever and orbital oedema occurred. Several days later diffuse myalgias occurred. Three patients presented neurological symptoms: left hemiplegia flexible paraplegia and limb paresis; these symptoms regressed spontaneously. 87% of the clinically suspected cases had specific serum antibodies (IFI, ID, IE). Hyperleucocytosis and hypereosinophilia were a constant factor. Anti-AH antibodies were detected by the Widal test. The histopathology characteristic of myositis was seen in the 12 muscle biopsies. Also observed was the precystic state of the larvae which is in agreement with the early timing of the samples which were obtained during the 3rd and 4rd week of infection.

During an 8-year period, 30 patients with gas-producing infections were admitted for treatment of hyperbaric oxygen. Infection was a consequence of trauma and operation in 26 cases and a complication of other diseases in 4 cases. The definitive diagnoses were clostridial myositis in 12 cases, clostridial cellulitis in 7, non-clostridial cellulitis in 9 (mainly E. coli infections); in 2 cases the diagnoses were uncertain. Six cases of E. coli infection were misinterpreted as myositis and were treated with hyperbaric oxygen at 3 atm. abs. without effect. Five of these cases were cured by antibiotic therapy and surgical drainage. The risk of hyperbaric oxygen at 3 atm. abs. necessitates a strong indication for this kind of treatment. Thirteen cases of clostridial infections (2 with cellulitis, 11 with myositis) were successfully treated with hyperbaric oxygen except in 2 cases of myositis. Helpful data for the plausible diagnosis clostridial myositis in the acute stage were: a typical clinical picture with rapid progress of the local necrosis and inflammatory reaction, roentgenographically demonstrable intramuscular gas, and abundance of gram-positive rods in exudate from the inflammation. Laboratory data had a limited value. In some cases of clostridial myositis, a fall of hemoglobin to low values (less than 7.5 g%) was seen in the first 24 hours and high values of hemoglobin/plasma were noted in 4 cases. Incidents of side-effects from hyperbaric oxygen treatment were frequent but only a few were serious and these subsided during a short interruption of the treatment.

The Committee on Infectious Diseases of the American Academy of Pediatrics, and the Advisory Committee on Immunization Practices of the Center for Disease Control for many years have recommended the routine use of influenza vaccine in various hemoglobinopathies including sickle cell disease. This recommendation, however, has not been included in the patient care protocols of the Comprehensive Sickle Cell Centers program of NIHLB. Most clinicians have not used yearly influenza vaccine for their patients with sickle cell disease. This article reports a case of a 5-year-old boy with sickle cell disease who had not received influenza vaccine. He developed pneumonitis and acute myositis during a serologically confirmed influenza B virus infection. The incapacitating and protracted course of his illness presented diagnostic and management problems. His case strongly supports the recommendation of the two infectious disease committees.

Since the recovery of its causative agent, Borrelia burgdorferi, in 1981, Lyme borreliosis has become the most prevalent tick-borne disease in the United States as well as in Europe. Its steadily increasing clinical spectrum now includes erythema migrans, acrodermatitis chronica atrophicans, lymphadenosis beniga cutis, arthritis, myocarditis, progressive meningoencephalitis, myositis, and various ocular and skin disorders. The true incidence of Lyme borreliosis in the world is unknown. In the United States, it has increased from 2,000 cases in 1987, to more than 8,000 in 1989. It occurs now in regions where the tick vectors, Ixodes dammini and Ixodes pacificus, are absent and where other species of ticks may be responsible for maintaining and distributing the spirochete. In Europe, Lyme borreliosis has been reported from 19 countries; its occurrence coincides with the distribution of the vector tick, Ixodes ricinus and possibly Ixodes hexagonus. Specific and dependable serological tests are still not available, but development of probes for specific antigens and the polymerase chain reaction appear promising in detecting ongoing infections and in identifying B. burgdorferi in ticks, animal, and human hosts. Brief reference is made to advances in the preparation of whole cell and genetically engineered vaccines.

Erythematous macules, nonpalpable and palpable purpura, and flaccid pustules developed in a 59-year-old man with acute lymphocytic leukemia 8 days after reinduction chemotherapy with cytosine arabinoside and daunorubicin. Tissue and blood cultures grew Fusarium proliferatum, and a skin biopsy specimen revealed fungal vasculitis. Anemia and muscle weakness accompanied the disseminated infection, for which the patient received granulocyte transfusions and amphotericin B, ketoconazole, rifampin, and griseofulvin. Skin lesions and fungemia resolved with recovery of the bone marrow, and 51 days after the completion of his chemotherapy he returned home. If promptly recognized and aggressively treated, disseminated fusariosis is responsive to therapy. Infection with Fusarium species should be suspected in profoundly neutropenic patients in whom disseminated palpable purpura and myositis develop concomitantly.

A previously unrecognized musculoskeletal syndrome led to the recognition of this "new" infectious disease. Several distinct patterns of musculoskeletal involvement can be seen throughout the course of untreated Lyme disease. Diffuse, nonspecific muscle achiness and stiffness can be seen early to be followed by characteristically brief, recurrent episodes of LIMP and transient arthritis that help to differentiate LD from other arthropathies. Chronic oligoarticular arthritis is seen in a few. Lyme arthropathy most closely resembles the reactive arthropathies. In a few cases, LD has mimicked other connective tissue disorders such as juvenile rheumatoid arthritis, rheumatoid arthritis, myositis, and scleroderma. It would appear that the full spectrum of musculoskeletal LD is still being defined.

The case of a 13-year-old girl with CVI is presented who required steroid treatment for myositis. After three weeks of treatment, the serum IgM level increased about ten-fold. Specific antibodies to vaccination antigens, which despite adequate vaccination were absent prior to any kind of treatment, could be synthesized following steroid treatment. The effects observed were only transient. Steroid influences on immunoregulatory T cell may have contributed to the improvement of humoral immunity in this patient.

Measurement of myeloperoxidase activity in the muscles of mice infected with Trichinella pseudospiralis, T. spiralis or both helminths allowed quantitation of host inflammatory response to the parasite. Infection of the host with T. pseudospiralis alone was accompanied by less inflammation in host diaphragm muscle than was the case in hosts infected with T. spiralis alone. A dramatic reduction in inflammation around s.c. implanted cotton string was observed in mice infected with T. pseudospiralis alone below that seen in uninfected mice. Concurrent infection of the host with T. spiralis and T. pseudospiralis resulted in a lowering of myositis below that seen in the diaphragm muscles of mice infected with T. spiralis alone.

Among 2175 patients seen over the last three years in a non-specialized department of internal medicine with no intensive care unit, 100 had supranormal serum lactic dehydrogenase activities. These patients' case-reports have been analyzed. Nearly half the patients (47/100) had a malignant disease (cancer or hemopathy). Among the remaining patients, 19 had a hepatic disorder (alcohol hepatitis in 10, viral hepatitis in 8, and isoniazide hepatitis in 1), 7 had a heart disease (heart failure with hepatomegaly in 5, myocardial infarction in 2), and 27 had various other conditions (including hemolysis in 6 and polymyositis en 3). The value of serum LDH assay is obvious in situations other than acute conditions such as myocardial infarction of pulmonary embolism; these are better known and have not been studied here as their prevalence was low among the patients enlisted in our study. In comparison to other enzymes (alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), transaminases (GOT, GPT) that were also routinely assayed in our patients, abnormal serum LDH activities are much less common and their significance is quite different. An increase in serum and their significance is quite different. An increase in serum LDH activity indicates a serious condition, often with a fatal outcome. The "various other conditions" group includes patients with hemolysis, hepatitis and myositis; the other patients in this group either had severe infectious diseases or died suddenly in the first few days of their hospitalization before diagnosis had been established. Each etiologic group has been analyzed to asses the characteristics of patients with increased LDH activity according to each etiology. Analysis of coincident abnormalities of the other enzymes listed above shows marked differences between etiologic groups; diagnostic accuracy can thus be enhanced in certain conditions. Most patients with malignancies had poorly differentiated tumors, with metastases: 28 had an epithelial tumor, with hepatic and/or bone metastases in 23 cases, 5 had cancer of the liver, 10 had a malignant hemopathy (2 lymphomas, 5 myeloproliferative syndromes, 3 acute leukemias), and 4 had a sarcoma. Cancer of the lung is the most common malignancy (10 cases) and may be responsible for increased serum LDH activity even in patients without metastases. Serum LDH assay is of value for monitoring the course in patients with initially increased activities as it falls under effective therapy and rises during exacerbations.
