Behçet's disease associated with amyloidosis in Turkey and in the world.

The association of amyloidosis with Behçet's disease has infrequently been reported in published works. Twenty four such cases have been observed in the world, of which 12 are from Turkey, including eight of ours. In all our eight cases renal biopsy showed amyloidosis of type AA. Behçet's disease of male preponderance, long duration, complete type, multiple organ involvement, and positive skin pathergy test were the main characteristics of all 24 cases of Behçet's disease with amyloidosis. We conclude that amyloidosis associated with Behçet's disease is a secondary AA amyloidosis occurring as an intrinsic manifestation of Behçet's disease.

Propranolol therapy for portal hypertension in children.

Administration of propranolol to 13 children with portal hypertension reduced splenic pulp pressure by greater than 50 mm H2O (P less than 0.01) in approximately 2 weeks, when the pulse rate became three fourths the initial rate. The influence was found to be greater in compensated than in decompensated portal hypertension. This observation might be interpreted to mean that the effect of propranolol in the reduction of portal venous pressure results not only from decreased intestinal blood flow secondary to decreased cardiac output but also to the stimulation of sympathetic nervous system alpha-adrenoreceptors of the portal tract. Although arterial blood pressure changes were not significant, peripheral venous pressure was reduced significantly (P less than 0.01). We conclude that propranolol has considerable usefulness in treating portal hypertension in children.

Familial cirrhosis.

Three pairs of siblings with cirrhosis were investigated. The histopathological examination of the liver biopsy specimens and the laboratory findings did not give any clue about the cause of the disease. The presence of familial cirrhosis was considered.

Osteoarticular pains and changes in Wilson's disease: a radiological study in fourteen patients in nine Turkish families.

A series of 14 patients with Wilson's disease were evaluated in order to determine the characteristic bone changes found in this metabolic disorder. The following radiologic and clinical findings deserve to be summarized: (1) Osteoarticular pains as first manifestations of Wilson's disease were found in six patients. (2) In all but 2 of our patients, minor or moderate or even severe bone abnormalities characteristic for Wilson's disease were observed. (3) There were three groups of sibs. Among these sibs, the lesions were not only similar in type but were also acquired approximately at the same time, showing the influence of the different genes responsible for this metabolic disorder.
