1/888. polymyositis with biological false-positive serological test for syphilis. A case report. A young female came to the clinic with polymyositis and a biological false-positive serological test for syphilis (BFP reaction). polymyositis, like other connective-tissue diseases, should be considered in the study of BFP reactors.

2/888. pyomyositis due to non-haemolytic streptococci. We present a unique case of a multifocal non-tropical pyomyositis due to non-haemolytic streptococci in a 36-y-old woman. The initial infection was in an area of contused muscle in the left anterior thigh and spread to the contralateral femoral and gluteal musculature. There was a previous history of staphylococcus aureus pyomyositis and colitis ulcerosa. The patient was treated successfully with surgical drainage and parenteral antibiotics. ( info) |
3/888. MRI of tuberculous pyomyositis. PURPOSE: The purpose of this article is to describe the findings of MRI in tuberculous pyomyositis (PM). METHOD: The MR images of four proven cases of tuberculous PM were retrospectively reviewed and analyzed with clinical and laboratory findings. The location, signal intensity on T1- and T2-weighted spin echo images, presence of abscess, signal intensity of peripheral rim, patterns of contrast enhancement, and associated findings were evaluated. RESULTS: On MR images, all cases demonstrated low signal intensity on T1-weighted images and high signal intensity on T2-weighted images in a single muscle. abscess was seen in all cases. Peripheral rim showed subtle hyperintensity on T1-weighted images and hypointensity on T2-weighted images. After gadolinium infusion, peripheral rim enhancement was observed in all cases. cellulitis was associated in one case. The patients clinically presented with a palpable mass of long duration. CONCLUSION: Tuberculous PM shows characteristic findings of a well demarcated abscess with rim enhancement at MRI and can be distinguished from other soft tissue masses. ( info) |
4/888. Reversible renal failure and myositis caused by phenytoin hypersensitivity. A 38-year old woman receiving phenytoin (diphenylhydantoin) noticed maculopapular erythema as the first manifestation of a syndrome that included acute renal failure and myositis in addition to fever, lymphadenopathy, exfoliative dermatitis, and hepatitis. prednisolone sodium phosphate therapy resulted in resolution of this hypersensitivity reaction, and she recovered from renal insufficiency. The occurrence of renal failure and myositis in the spectrum of phenytoin hypersensitivity reactions is discussed, and the importance of a morbilliform rash in a patient receiving phenytoin is emphasized.

5/888. Focal, steroid responsive myositis causing dropped head syndrome. The dropped head syndrome, which occurs in a variety of neuromuscular disorders, is usually not due to an inflammatory process and generally either self-limited or nonresponsive to therapy. We present an 80-year-old woman who developed progressive neck weakness over a few months due to a focal and restricted inflammatory process involving the neck extensor muscles. She responded dramatically to treatment with immunosuppressive therapy. ( info) |
6/888. Focal myositis presenting with radial nerve palsy. Focal myositis is a rare inflammatory pseudotumor of skeletal muscle which usually has a benign course. We report a 56-year-old woman with a painful mass in the left arm with a radial nerve palsy. magnetic resonance imaging (MRI) of the left arm showed a mass in the triceps muscle that was suggestive of a soft-tissue sarcoma. electromyography showed a severe radial neuropathy involving both motor and sensory axons. An open biopsy showed focal myositis. Treatment with corticosteroids resulted in complete disappearance of the mass clinically and by MRI, without recurrence for more than 2 years. radial nerve function also recovered completely. As a treatable cause of focal neuropathy, focal myositis should be included in the differential diagnosis of a muscle mass. ( info) |
7/888. Abdominal-wall myositis secondary to intra-arterial chemotherapy for femoral osteosarcoma. With the increasing application of intra-arterial chemotherapy (IAC), new side-effects are encountered. We describe two children with proximal femoral osteosarcoma who developed focal myositis of the abdominal wall musculature after IAC. In both cases, myositis presented as abdominal pain and mimicked acute abdomen. US demonstrated asymmetrical thickening of abdominal-wall musculature in the right lower abdomen. This diagnosis should be considered when evaluating the patient with unexplained abdominal pain and a history of IAC. ( info) |
8/888. Vesicoureteral reflux in a boy presenting with difficulty in walking. BACKGROUND: We report an uncommon case who presented himself at our hospital with main complaints of high fever and difficulty in walking due to pain on extension of his right lower extremity. methods: He was diagnosed, through investigation of his urinary tract, as having secondary psoas pyomyositis spread from acute pyelonephritis caused by vesicoureteral reflux. RESULTS: He was successfully managed firstly by antibiotic therapy, followed by the correction of reflux by ureteroneovesicostomy. ( info) |
| Kawasaki's disease is an inflammatory syndrome of young children that affects multiple organ systems. The most common ophthalmologic manifestations of Kawasaki's disease are bilateral conjunctival injection and nongranulomatous iridocyclitis. To our knowledge, this patient is the first with Kawasaki's disease to demonstrate extraocular muscle palsy and orbital myositis. ( info) |
| scleromyxedema is a sclerotic variant of papular mucinosis, in which lichenoid papules and scleroderma-like features are present. We describe a patient with scleromyxedema with IgG type lambda chain paraprotein, a systemic sclerosis-like illness, and myositis. The patient's serum contained Scl 70 antibodies, characteristic of scleroderma. electromyography showed signs of acute myositis and the creatine phosphokinase (CPK) level was elevated. Multiply passaged fibroblasts from the patient's skin lesions showed altered growth response in vitro. The patient was treated with cyclosporin (4 mg/kg/day) with improvement. ( info) |
