Manifestations and outcome of treatment of thyrotoxicosis: a clinical study.

We studied a series of 89 consecutive patients who presented with thyrotoxicosis at a medical unit. Clinical parameters and laboratory abnormalities were recorded. Treatment was initiated and response in terms of side-effects, clinical and laboratory remissions were monitored. The frequency of the various clinical manifestations, cardiovascular and neurological complications were documented. Laboratory data on electrolytes, haematological changes and thyroid antibodies were noted. The treatment outcome revealed a relapse of 37.7% in patients with 6 months of treatment (90% occurred within the first year). We also noted that 6.7% of patients developed skin reaction. A treatment default rate of 30% was noted.

Nerve sheath myxoma of the breast. A light and electron microscopic, histochemical and immunohistochemical study.

A nerve sheath myxoma involving the breast has been examined by light and electron microscopy, and by immunohistochemical and histochemical methods. Electron microscopically, cells with features indicative of Schwann cells, perineural cells and fibroblasts were identified in the tumour and S-100 protein and vimentin positivity was demonstrated in the tumour cells. The mucoid matrix stained positive for chondroitin-4 or 6-sulphate in keeping with a cartilaginous lesion. These findings are discussed in relation to the uncertain histogenesis and the differential diagnoses of the tumour in the breast.

Neonatal gastrointestinal perforation.

During the 7-year period from 1980 to 1986, 56 neonates with gastrointestinal (GI) perforation were treated in the Hospital for Sick Children, London. The overall mortality rate was 30%. The highest mortality rate (60%) was associated with gastric perforation, which in this series occurred only in premature neonates. Colorectal perforation carried the lowest risk of mortality (17%). The mortality rate from small bowel perforation was 35%. Prematurity and low birth weight were significant factors increasing the mortality rate from neonatal intestinal perforation. The predominant cause of perforation in the small and large intestine was necrotizing enterocolitis and the most common site of perforation was the terminal ileum. Mechanical ventilation was thought to be the cause of the perforation in four of the five neonates with gastric perforation. Primary anastomosis is a definite option in neonates who are stable intraoperatively. The mortality rate and in-patient stay for neonates who had primary anastomosis were less than for those who had stomas.

Acquired platelet dysfunction with eosinophilia: review of seven adult cases.

Seven adults with acquired platelet dysfunction with eosinophilia presented with histories of spontaneous bruising and three also had moderate thrombocytopenia. Six patients had platelet function tests performed and all showed variable storage pool defects. When assayed, IgE concentrations were raised. Although only two patients had parasites isolated in their stools, all seven responded to antihelminth treatment. It is speculated that the IgE response to parasites mediates mast cell degranulation, which leads to in vivo platelet activation.

CA 125 in peritoneal fluid and serum of patients with endometriosis.

Serum and peritoneal fluid collected from 48 patients at laparoscopy was assayed for CA 125. Geometric mean serum CA 125 was similar in 21 patients with predominantly early stage endometriosis (13.4 U/ml; confidence intervals (C.I.) 10.8-16.7) and 27 patients without endometriosis (12.9 U/ml; C.I. 9.7-17.2). Mean peritoneal fluid CA 125 was higher in the endometriosis patients (mean 44.4 U/ml; C.I. 34.5-57.2) than controls (35.7 U/ml; C.I. 30.0-42.2), but the difference was not significant. Peritoneal fluid volume was increased in endometriosis patients (p = 0.013), and only after correction for peritoneal fluid volume did total antigenic concentration in aspirated peritoneal fluid show significant elevation (p = 0.0015) in endometriosis patients (mean 340 U/ml; C.I. 212-547) compared with controls (125 U/ml; C.I. 85-184). These results suggest that although CA 125 may be expressed in peritoneal fluid in endometriosis, it is unlikely to be of use as a marker of disease activity in peritoneal fluid obtained by culdocentesis.
