Prognostic factors in ganglionic and thalamic haemorrhages: a clinical and radiological study.
Clinical and radiological features of 43 patients admitted for ganglionic (21) and thalamic (22) haemorrhages were studied to ascertain the factors that would determine prognosis in the acute stage of the illness. Nineteen patients died, 16 of them in the first week. The adverse clinical factors were an altered state of consciousness, decorticate/decerebrate posturing, ataxic respiration, abnormalities of gaze and presence of bilateral Babinski's sign. Adverse radiological factors were the presence of thalamic haemorrhage of 3 cm or more, intraventricular spread of the haemorrhage and midline shift of 0.5 cm of more. The significance of these findings is discussed.

Yet another cause of chronic viral hepatitis?
The clinical features, course and histology of liver in 20 patients; mostly middle aged to elderly females, closely resembling chronic Non A Non B hepatitis is presented. They presented quite late in their disease and therefore, complications such as variceal bleeds, ascites and encephalopathy were frequent. Our patients were negative for hepatitis B and C virus serology. Metabolic and immune causes of chronic liver disease were also ruled out. To the best of our knowledge, this is the first study of its kind elaborating the clinical features, course and histology of liver in chronic Non B Non C hepatitis and raises a number of questions as to the nature of the infecting virus and the epidemiology of disease.

Supervised training of practical procedures in the internal medicine residency.
In order to get feedback whether the medical residents are getting adequate supervised training to perform practical procedures, a questionnaire was distributed among the residents asking their involvement in sixteen frequently performed procedures in the medical unit of the Aga Khan University Medical Centre. Though the residents were satisfied about their training in doing lumbar punctures, pleural and peritoneal aspirations, bone marrow aspiration and trephine and chest tubes placement, they showed their concern about training in putting central lines, venous cut downs, cardiac pacing and biopsies. A better schedule training programme, organized subspecialty rotation, continuous evaluation of resident's skill, credentialing procedures and willingness on the part of faculty to teach and residents to learn may improve the training.

Barrett's oesophagus and Helicobacter pylori.
In order to demonstrate the presence of Helicobacter pylori in the metaplastic epithelium of Barrett's oesophagus and to evaluate its possible association with this entity, we examined 29 cases of Barrett's oesophagus where concomitant antral biopsies were also available. These cases were compared with an equal number of age and sex matched controls of uncomplicated reflux oesophagitis. H. pylori was present in 11 of 29 cases of Barrett's oesophagus (38%). No increase in the frequency of H. pylori antral gastritis was found in patients of Barrett's oesophagus compared to the control group of uncomplicated reflux oesophagitis. The positivity of Barrett's oesophagus for H. pylori correlated with the presence of H. pylori antral gastritis (P < 0.05), although in two cases of H. pylori-positive Barrett's oesophagus antral biopsies were negative for H. pylori. No difference was found in the severity of inflammatory and dysplastic changes of H. pylori-positive and H. pylori-negative Barrett's oesophagus. Presence of H. pylori does not seem to alter the natural history of Barrett's oesophagus.
