12/780. Visceral larva migrans and tropical pyomyositis: a case report.

    We report a case of tropical pyomyositis in a boy who presented with a severe febrile illness associated with diffuse erythema, and swelling in many areas of the body which revealed on operation extensive necrotic areas of various muscles that required repeated debridement. The patient gave a history of contact with dogs, and an ELISA test for toxocara canis was positive. He also presented eosinophilia and high serum IgE levels. staphylococcus aureus was the sole bacteria isolated from the muscles affected. We suggest that tropical pyomyositis may be caused by the presence of migrating larvae of this or other parasites in the muscles. The immunologic and structural alterations caused by the larvae, in the presence of concomitant bacteremia, would favour seeding of the bacteria and the development of pyomyositis.

13/780. Primary sjogren's syndrome with severe central nervous system disease.

    OBJECTIVE: central nervous system (CNS) involvement in primary sjogren's syndrome (pSS) is controversial with regard to frequency, significance, and etiology. methods: We describe a young woman with pSS and severe CNS disease and review the literature on the pathophysiology, clinical significance, symptoms, diagnostic examinations, and treatment of CNS disease with concomitant pSS (CNS-SS). RESULTS: Our patient with pSS had a 5-month history of benign lymphadenopathy and myositis, after which she developed severe CNS disease, vasculitic lesions on her hands, and a neurogenic bladder attributable to spinal cord involvement. The diagnosis was based on the clinical picture and the results of a brain magnetic resonance imaging (MRI) scan, electroencephalography (EEG), and cerebrospinal fluid (CSF) analysis. The disease did not respond to corticosteroids, but the administration of cyclophosphamide resulted in recovery. In the literature, the incidence of CNS-SS varies widely, from rare to incidence rates of 20% to 25%. The clinical picture is diverse, ranging from mild cognitive symptoms to fatal cerebrovascular accidents. The pathophysiology of CNS-SS is unclear, specific diagnostic methods are not available, and diagnosis is based on the clinical picture and a combination of examinations. MRI is the most sensitive test and cerebral angiography the most specific. CSF reflects involvement of the leptomeninges, and EEG is nonspecific. There are no controlled studies of the treatment of CNS-SS. Regimens for vasculitis are commonly used. CONCLUSIONS: CNS-SS is uncommonly recognized and difficult to diagnose. Increasingly accurate and available diagnostic examinations will yield more information about the association of CNS disease with pSS.

14/780. Myositis associated with a Baerveldt glaucoma implant.

    PURPOSE: To describe a case of myositis in the presence of a Baerveldt glaucoma implant. METHOD: Case report. RESULTS: A 41-year-old black woman developed myositis after placement of a Baerveldt glaucoma implant. Echography demonstrated migration of the seton plate against the medial rectus muscle insertion. Myositis resolved after removal of the Baerveldt glaucoma implant. CONCLUSION: The Baerveldt glaucoma implant may have precipitated myositis in this patient.

15/780. Muscle infections caused by Salmonella species: case report and review.

    We describe a patient with salmonella pyomyositis and review 30 other cases reported during the past 4 decades. Men outnumbered women by 2.9 to 1, and the median age of the patients was 51 years. Approximately one-half the cases were caused by salmonella enteritidis. Infected vascular aneurysms were observed in seven patients. Prior salmonella infections and local trauma or lesions were common. Diverse underlying conditions, mainly diabetes and human immunodeficiency virus infection, were present in 81% of the patients, and the psoas muscle was involved in 55% of the cases. One-third of the patients died, and relapses were common after a median time of 5 weeks (range, 4.5-27 weeks) in those who survived. Most patients had anemia, and pathogens were recovered from blood samples from two-thirds of the patients. Salmonella should be considered as a causative agent of muscle infections in the appropriate clinical setting, particularly in patients with underlying diseases or preexisting vascular aneurysms.

16/780. Unusual case of septic arthritis of the hip: spread from adjacent adductor pyomyositis.

    Distinguishing intracapsular and extracapsular hip infections may be clinically difficult. Because of this difficulty in diagnosis, the spread of an extracapsular infection into the hip joint may be missed and lead to significant joint destruction. The case of a patient who suffered from the spread of adductor pyomyositis to the hip joint is reported. The delay in diagnosis of an intracapsular hip infection led to significant intra-articular destruction and ultimately necessitated a Girdlestone resection arthroplasty. The patient's hip function was salvaged with a total hip arthroplasty. The presence of an extracapsular hip infection should mandate serial physical examinations and aggressive evaluation to rule out intracapsular spread. A delay in diagnosis of an intracapsular hip infection can lead to catastrophic results.

17/780. S-1 radiculopathy as a possible predisposing factor in focal myositis with unilateral hypertrophy of the calf muscles.

    Associated with chronic S-1 radiculopathy, a 44-year-old man developed unilateral hypertrophy of the calf muscles. electromyography revealed neurogenic alterations in the corresponding limb compatible with S-1 radiculopathy. In addition, MR-tomographic and bioptic findings were consistent with a focal inflammatory myopathy of the enlarged right gastrocnemius muscle. Predisposing factors for the localisation of a focal myositis are unknown. This case report highlights the diagnostic difficulties in distinguishing focal myositis and denervation hypertrophy following S-1 radiculopathy or secondary inflammation related to denervation. We consider the possibility that in our case the inflammatory process might have been triggered by electromyographically proven chronic denervation related to radiculopathy.

18/780. An outbreak of acute eosinophilic myositis attributed to human sarcocystis parasitism.

    Seven members of a 15-man U.S. military team that had operated in rural malaysia developed an acute illness consisting of fever, myalgias, bronchospasm, fleeting pruritic rashes, transient lymphadenopathy, and subcutaneous nodules associated with eosinophilia, elevated erythrocyte sedimentation rate, and elevated levels of muscle creatinine kinase. Sarcocysts of an unidentified sarcocystis species were found in skeletal muscle biopsies of the index case. albendazole ameliorated symptoms in the index case; however, his symptoms persisted for more than 5 years. Symptoms in 5 other men were mild to moderate and self-limited, and 1 team member with laboratory abnormalities was asymptomatic. Of 8 team members tested for antibody to sarcocystis, 6 were positive; of 4 with the eosinophilic myositis syndrome who were tested, all were positive. We attribute this outbreak of eosinophilic myositis to accidental tissue parasitism by sarcocystis.

19/780. Nodular sarcoid myositis of skeletal muscle diagnosed by fine needle aspiration biopsy. A case report.

    BACKGROUND: Symptomatic striated muscle involvement in sarcoidosis is rare. Muscle biopsy is usually required for the diagnosis. Fine needle aspiration biopsy (FNAB) has been successfully used in diagnosing soft tissue lesions. To the best of our knowledge, FNAB of sarcoid myositis has not been reported. CASE: A 31-year-old, black female with a history of sarcoidosis presented with an enlarging, painful, left calf mass. Infected thrombi were suspected. FNAB showed numerous loosely arranged epithelioid histiocytes, multinucleated giant cells and skeletal muscle cells. The overall cytologic picture was that of granulomatous myositis. The cytologic features coupled with the patient's history and magnetic resonance imaging findings suggested sarcoid myositis. Subsequent muscle biopsy showing noncaseating granulomata and negative stains for organisms confirmed the diagnosis of nodular sarcoid myositis. CONCLUSION: Nodular sarcoid myositis can be suggested by FNAB cytology in a patient with a past history of sarcoidosis.

20/780. First report of tropical myositis and crescentic glomerulonephritis in a renal transplant recipient.

    We describe a renal transplant recipient who presented with tropical myositis and acute allograft dysfunction 2(1/2) years after transplantation. Graft biopsy showed immune-complex crescentic glomerulonephritis. He was receiving only 7.5 mg/d of prednisolone for more than 2 months before presentation. Renal function did not improve despite treatment with antibiotics, methylprednisolone pulse therapy, and cyclophosphamide. He died of septicemia.
