Detection of migratory silicone pseudotumor with use of magnetic resonance imaging.

A patient with silicone gel breast implants, who experienced capsular contracture of the left breast that was treated by closed capsulotomy, sought medical attention because of numbness and pain in the left medial forearm and hand. Inflammatory masses subsequently developed in the left anterior axillary and antecubital regions. Magnetic resonance imaging revealed silicone pseudotumors, and mammography confirmed implant rupture and gel extrusion along fascial planes into the axillary region.

Isolated polyarteritis nodosa of the male reproductive system.

Polyarteritis nodosa (PAN) frequently affects the testis and epididymis. We describe a 29-year-old man with isolated PAN of the testis and review reported cases of isolated PAN of the testis or epididymis. Our patient underwent orchiectomy and at followup 17 months later was without evidence of recurrence or development of systemic PAN.

Tricuspid valve papillary fibroelastoma: echocardiographic characterization.

We report a tricuspid valve papillary fibroelastoma initially detected by transthoracic two-dimensional echocardiography and subsequently characterized by transesophageal two-dimensional echocardiography. The mass was excised during open heart operation, and the diagnosis was verified grossly and histopathologically. Transesophageal echocardiography usually provides images far superior to those from transthoracic echocardiography and may be a useful adjunct for intraoperative localization of intracardiac tumors for excision.

Factor VIII-von Willebrand factor in giant cell arteritis and polymyalgia rheumatica.

Levels of three factor VIII-von Willebrand factor components (von Willebrand antigen, ristocetin cofactor, and factor VIII coagulant) were higher in specimens of plasma from 27 patients with giant cell arteritis and 18 patients with polymyalgia rheumatica than in specimens from 21 normal control subjects. Values in patients with active giant cell arteritis were higher than those in patients with either inactive giant cell arteritis or active polymyalgia rheumatica. Levels of factor VIII-von Willebrand factor components tended to decline gradually after disease activity had been suppressed by corticosteroid therapy and therefore may be indicators of vascular damage. These levels, however, did not revert to normal rapidly in response to corticosteroid therapy as did the patients' symptoms and the usual laboratory measurements indicative of inflammation; thus, measurements of these components are unlikely to be useful in day-to-day management of these diseases. Electrophoretic analysis suggested that the elevated values are due to increased amounts of normal factor VIII-von Willebrand factor rather than to the presence of an abnormal molecule.

Polymyositis associated with jejunoileal bypass.

We report a patient with polymyositis who had a functioning jejunoileal bypass. Although many connective tissue syndromes have been reported with small bowel bypass, the association of polymyositis is unusual even though similar pathogenetic mechanisms might be involved.

Immunopathology of rheumatic pericarditis.

Immunologic mechanisms have been implicated in the endocarditis, myocarditis, and arthritis of acute rheumatic fever. However, pericarditis, a major manifestation of acute rheumatic fever with a clinical incidence of 5-10%, has not been studied. We have evaluated a patient who had this febrile disease with arthritis and pericarditis. Pericardial tissue showed extensive deposition of IgG, IgM, and C3 both on the pericardial surface and within the walls of pericardial blood vessels. Our findings of immunoglobulins and complement within the inflamed pericardium suggest an immune-mediated mechanism for the pericarditis of acute rheumatic fever.

Improved control of non-insulin-dependent diabetes mellitus by combined halofenate and chlorpropamide therapy.

Combined halofenate-chlorpropamide was evaluated for the treatment of NIDDM. Four subjects treated with 500 mg/day chlorpropamide were given 500-1000 mg halofenate daily for 48 wk or longer. Fasting plasma glucose fell from 210 +/- 16 (+/- SEM) (11.67 +/- 0.89 mM) to 107 +/- 10 mg/dl (+/- SEM) (5.94 +/- 0.55 mM), P less than 0.005. Twelve additional subjects were entered into a 16-wk double-blind study testing chlorpropamide plus either placebo or halofenate. In the halofenate group, the mean fasting glucose fell from 227 +/- 27 (+/- SEM) (12.61 +/- 1.50 mM) and reached 107 +/- 19 mg/dl (+/- SEM) (5.94 +/- 1.06 mM) during the fourth month, whereas the placebo groups showed a decrease from 242 +/- 22 (+/- SEM) to 208 +/- 29 mg/dl (+/- SEM) (P less than 0.005). In addition, halofenate reduced the height of postprandial glycemic excursions by lowering fasting plasma glucose. When halofenate was used as the only therapy, reduction in fasting plasma glucose was small [179 +/- 12 reduced to 142 +/- 8 mg/dl (+/- SEM); 9.94 +/- 0.67 mM and 7.89 +/- 0.44 mM], P less than 0.05.
