Electron microscopical study of myocardial biopsy material in congenital heart block.

Myocardial tissue from the left ventricle of two children with congenital atrioventricular block and recurrent Admas-Stokes attacks was obtained during the procedure of epicardial pacemaker implantation and studied with the electron microscope. One patient had a familial cardiomyopathy, the other had no clinical abnormality apart from the conduction defect. Proliferation of mitochondria was common in both cases. Focal interstitial fibrosis and pronounced proliferation of transverse tubules were found in the myocardial cells of the patient with familial cardiomyopathy. Deep invaginations of the sarcolemmma with formation of intracytoplasmic channels were present in the second case. The possibility that the numerous transverse tubules could serve as additional pathways for impulse conduction is discussed.

Ultrastructural features of mast cells in systemic mastocytosis.

A 3-year-old boy with systemic mastocytosis has been observed since the age of 4 months when he was first diagnosed as suffering from urticaria pigmentosa. Involvement of skin, liver, spleen and bones was observed. The electron microscopy of skin and liver revealed varied alterations in the morphology of mast cells. The most important findings were irregularly-shaped cells and unusual long and interdigitated cytoplasmic villi, with consequent aggregation of mast cells which was more prominent in the dermis. Proliferation and accumulation of mitochondria in one part of the cell and deeply indented nuclei were frequent. The problem, whether the morphological changes encountered--especially the complex interdigitation of villi--should be interpreted as a sign of expected neoplastic development, is discussed.

New observations in the clinical spectrum of the Budd-Chiari Syndrome.

Some observations on the natural history, surgical management and metabolic phenomena in B.C.S. are presented. In one patient side to side portocaval shunt brought dramatic improvement with asymptomatic followup of 5 years. The patient died of causes unrelated to B.C.S. At postmortem the shunt was patent and normal liver architecture was preserved. The second patient presented with a fulminant course culminating in acute hepatorenal syndrome. There was marked hypofibrinogenemia and extreme elevation of SGOT. Emergency portocaval shunt was followed by marked improvement in liver status. The patient died of respiratory complications on the 8th postoperative day. The third patient is one year on conservative treatment only and well. In this patient excessive renal tubular reabsorption of sodium at a distal site was documented. This may explain the generalised edema formation in patients with B.C.S. even without inferior vena cava obstruction. This is apparently the first reported instance of renal tubular function studied in B.C.S.
