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.

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.

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.

Infection of 60 to 90% of neutrophils with the protozoa, Hepatozoon canis, was detected in 2 dogs. Clinical signs included lethargy, anorexia, and weight loss. Both dogs had severe anemia, leukocytosis, and thrombocytopenia as well as hypoalbuminemia, hyperglobulinemia, and high activities of serum alkaline phosphatase and creatine kinase. Both dogs were treated with imidocarb dipropionate and doxycycline. One dog recovered clinically, with disappearance of parasites from WBC. The other dog died, despite treatment. Necropsy revealed widespread dispersion of schizonts in the parenchymal tissues, but no involvement of skeletal muscle tissues. The disease syndrome that has been identified in the Texas Gulf region is characterized by gait abnormalities associated with multifocal pyogranulomatous myositis, thus, it is distinct clinicopathologically from the syndrome observed in these 2 dogs.

While uncommon, many musculoskeletal disorders may be seen in association with the acquired immune deficiency syndrome (AIDS). Infections such as osteomyelitis, bacterial myositis and septic arthritis, neoplasms such as non-Hodgkin lymphoma and Kaposi sarcoma, and myopathies and polymyositis have been reported in this patient population. Computed tomography and magnetic resonance imaging frequently detect unanticipated musculoskeletal disease in a patient with AIDS, and may further help to distinguish infections from neoplastic disorders.

Over the period 1985 through 1994, observations are conducted on forty-eight patients, 35 men and 13 women, with age ranging from 11 to 56 years, presenting anaerobic non-spore-forming infection of the soft tissues (necrotizing fasciitis (3), postinjection nonclostridial myositis (7), crepitant cellulitis in diabetic gangrene (21), neck phlegmon (5), perineal phlegmon (9), and progressive bacterial synergistic gangrene against the background of chronic osteomyelitis (3). Infection development is characterized by local necrotic processes, intoxication, crepitations, fetor, fever, and in part of the patients--septic shock and DIC syndrome. The microbiological study shows presence of anaerobes, as mono- and polyinfection, aerobic-anaerobic associations, and gram-negative aerobes--in one patient alone. Invariably, the general condition is rather serious. Lethality amounting to 12.5 percent is ascribed to the late detection and unspecified and inadequate treatment protocol in the initial period of observation. The treatment is complex: incisions with successive many-staged necrectomies, antibiotics, metronidazole, hyperbaric oxygenation and hemadsorption. If several (2-3) of the aforementioned symptoms are present, evidence of anaerobic flora should be mandatory and purposefully seeked.
