We report a case of complete branchial fistula in an 18-year-old woman which could be demonstrated by a contrast study. The tract was completely excised and the patient had an uneventful recovery. Branchial fistulae are formed due to the persistence of the embryonic second branchial cleft. Complete fistulae with the internal opening in the region of the tonsillar fossa are not common.
A rare case of parathyroid cyst in a forty six-year-old lady diagnosed clinically as solitary thyroid nodule is reported. An intra-operative diagnosis of parathyroid cyst was made which was confirmed histopathologically. The clinicopathologic aspects, diagnostic methods and treatment modalities of this unusual condition are briefly discussed.

Five children with 'paroxysmal cold haemoglobinuria' are described. In all of them an upper respiratory tract infection preceded the episode of acute intravascular haemolysis and potentially pathogenic organisms were recovered from four. The haematological features are presented and the importance of technique in the detection of the pathognomonic antibody is stressed and discussed in detail. Although the clinical manifestations are usually self-limiting and of short duration, it may be necessary, because of the rapidity and severity of anaemia, to provide interim support with appropriate blood transfusion. Since the disease is not usually recurrent and not clearly related to exposure to cold, it is suggested that it be re-named Donath-Landsteiner haemolytic anaemia.
We report on a case of adriamycin cardiotoxicity occurring in a five-year-old boy treated for rhabdomyosarcoma. In addition to the usual features of myofibrillary degeneration associated with adriamycin, extreme endocardial fibrosis and mural thrombosis affecting the apical segments of both ventricles but particularly the left ventricle was seen at necropsy. The changes resembled classical endomyocardial fibrosis.

Although 125I-fibrinogen becomes associated with washed platelets from normal human subjects during ADP-induced shape change and aggregation, 125I-fibrinogen did not become associated with washed plateletes from a thrombasthenic subject during ADP-induced shape change and the platelets did not aggregate. Platelets from control and thrombasthenic subjects were treated with chymotrypsin, which is known to degrade platelet membrane glycoproteins. More 125I-fibrinogen became associated with chymotrypsin-pretreated platelets from normal subejcts than with untreated platelets, and fibrinogen caused the enzyme-treated platelets to aggregate. 125I-fibrinogen did not become associated with chymotrypsin-pretreated thromobasthenic platelets, and fibrinogen did not aggregate them. Thus, there appears to be a defect in thrombasthenic platelets that prevents the association of fibrinogen with them.
