Esophageal candidiasis following omeprazole therapy: a report of two cases.

Esophageal candidiasis was diagnosed at endoscopy in two patients receiving omeprazole therapy. There was no clinical evidence of immunosuppression or any obstructive lesion in the esophagus. There was prompt response of oral ketoconazole. These cases suggest that marked acid reduction may predispose to esophageal candidial infection.

Serum pepsinogen levels in patients with gastro-duodenal lesions.

Serum pepsinogen (SP) levels were studied in 100 patients with gastroduodenal lesions, and 100 healthy volunteers. SP levels were significantly elevated in patients with duodenal ulcer (DU) and duodenitis compared to the controls. SP values above 150 ug Tyr/ml/24 hr were highly suggestive of duodenal ulcer disease. Age and sex of patients and controls did not influence SP levels. The mean values of SP in North India were found to be lower in both normal and DU subjects compared to the west.

Ascitic fluid cholesterol in differential diagnosis of ascites.

Cholesterol was estimated in ascitic fluid of 89 patients (29 malignant and 60 non-malignant ascites). Mean ascitic cholesterol level was significantly higher in malignant ascites (89.52 mg/dl) as compared to non-malignant ascites (29.93 mg/dl). At a cut off value of 48 mg/dl, the sensitivity, specificity, positive and negative predictive value and overall diagnostic accuracy for diagnosing malignant ascites is 96.5%, 96.6%, 93.3%, 98.3% and 96.6% respectively. Ascitic fluid cholesterol estimation is an easy and reliable test for differentiating malignant ascites from non-malignant ascites.

Indolent gastric carcinoma.

A 55 year old woman presenting with epigastric pain and dyspeptic symptoms was diagnosed to have gastric carcinoma on endoscopic biopsy independently on two occasions. She was subsequently asymptomatic without any specific therapy till she developed gastric outlet obstruction and weight loss four years later. Histology of the resected specimen revealed an adenocarcinoma infiltrating the serosa without any evidence of metastasis.

Course and prognosis of ulcerative colitis.

A study of 50 patients (23 males and 27 females) of ulcerative colitis, who were on follow-up showed that maximum number of patients had the disease before the age of 50 years. At the onset, the activity of the disease was severe in 44%, moderate in 32% and mild in 24% of cases. The commonest clinical course of the disease was chronic intermittent type (48%), followed by single attack with subsequent remission (42%). Chronic continuous type was seen in 10% patients only. There was no correlation of the extent of the bowel involvement with the clinical course. The precipitating factors for the onset or reactivation of the disease appeared to be emotional disturbances in 18% and pregnancy in 8%. The complications, both local and systemic, were not frequent. Serious complications like massive haemorrhage, perforation, toxic megacolon and carcinoma colon were not seen at all.

Prognostic significance of transient type II second degree atrioventricular block induced during exercise testing.

During exercise testing a 70 years old male developed Type II second degree AV block which reverted in recovery period. On follow up 3 months later, he developed symptomatic 2: 1 atrioventricular block and required permanent pacemaker implantation.

Endoscopic and histopathological study of duodenitis.

Fifty patients who presented with symptoms suggestive of disease related to peptic acidity having endoscopic evidence of duodenitis were analysed. Endoscopic duodenal biopsy was done in all these patients. Histologically duodenitis was labelled if there was infiltration of epithelial layer. Male to female ratio was found to be 3:2. Duration of symptoms in the patients ranged from less than one month to more than 5 years. Possible aetiological factors like drugs, alcohol and smoking were established in 26 patients (52%), drugs being the commonest (26%). Stool examination showed cyst or ova of parasites in 8 patients (16%). Endoscopically multiple hyperaemic patches were seen in 15 (30%), erosions in 19 (38%), coarse mucosal folds in 5 (10%), nodules in 2 (4%) and multiple lesions in 9 (18%) patients. Histological and endoscopical correlationship was established in 40 (80%) cases.

Jaundice in Plasmodium falciparum.

Thirty-two patients of smear positive Plasmodium falciparum malaria having jaundice were analysed retrospectively. Majority of the cases were in the age group of 31-40 years. Serum bilirubin levels ranged from 2 mg to 40 mg%. Fourteen (42.6%) had serum bilirubin above 10 mg%. Conjugated bilirubinaemia was found in twenty one patients (65.5%), unconjugated in 4 (12.5%) while 7 patients (21.8%) had a mixed pattern. Serum transaminases were high in 21.8% patients. Twenty five patients (78%) had associated azotaemia, 11(34.3%) had intravascular haemolysis and 3(9.3%) had possible cerebral malaria. Hepatosplenomegaly was seen in all the 32 patients. Mortality was 21% but none died of hepatic encephalopathy. Histologically the most consistent finding in liver biopsies was reticulo-endothelial cell hyperplasia. Pigmentation in kupffer cells, fatty change, sinusoidal and portal infiltration and cholestasis were the other features seen.
