ABSTRACT
Nonfunctioning islet cell tumors commonly cause no symptoms. A 22-year-old woman presented with lump in the left hypochondrium, refractory high-protein ascites and evidence of left-sided portal hypertension. At exploratory laparotomy, a 30 cm x 15 cm mass was seen at the splenic hilum, with large collateral vessels around. Distal pancreatectomy with splenectomy was done. Histology of the mass showed malignant islet cell tumor infiltrating the spleen. The patient died in the postoperative period.

BACKGROUND: Eradication of Helicobacter pylori infection is known to decrease the recurrence rate of peptic ulcer disease. Data from India on the acquisition rate of H. pylori infection and reinfection after eradication are scant. AIM: To study the rates of acquisition of H. pylori infection and of reinfection after eradication in Indian adult patients. METHODS: We evaluated 116 consecutive patients with dyspepsia undergoing endoscopy. Sixty-four of them were H. pylori-positive on gastric antral biopsy (rapid urease test and histology). Patients diagnosed to have H. pylori infection were treated with a four-drug regimen (omeprazole, bismuth subcitrate, tetracycline, furazolidine) for 2 weeks; those failing H. pylori eradication were treated with a second regimen (lansoprazole, amoxycillin, secnidazole) for one week. Patients who were H. pylori-negative to begin with and those who had successful H. pylori eradication were followed up clinically and endoscopically every 3 months for a median of one year. RESULTS: Ninety-six patients (50 H. pylori-positive) were available for study; the other 20 were lost to follow up after the first endoscopy. Fifty of the 96 (52%) were H. pylori-positive; four of these 50 patients did not follow up after first treatment. The eradication rate with the four-drug regimen was 89.1% (41/46). Four of the 5 non-responders eradicated H. pylori with the second regimen. At the end of median one year follow-up (range 9-15 months), one of the 45 patients (2.4%) who eradicated the organism developed reinfection; none of the 46 patients who were initially H. pylori-negative acquired new infection. CONCLUSIONS: The risk of reinfection after eradication is low in Indian subjects at the end of one year. The rate of acquisition of new infection is also low in the adult population.

Giant cell tumour (osteoclastoma) of talar bone is a rare entity and is seen more commonly in the third decade of life. We report this disease entity in a 17-years-old girl. The patient presented with painful swelling of the left ankle with an osteolytic lesion in the talus on conventional radiographs. Intralesional curettage and autologous bone grafting was performed following which patient's pain and swelling disappeared. Complete range of movement at the ankle joint was regained with minimal restriction at the subtalar joint. There is no evidence of relapse at six months follow up.

We assessed the efficacy and safety of Shanvac-B, a new recombinant hepatitis B vaccine developed in India. Eighty-one healthy volunteers (75 women, 6 men; aged 18-40 yr), negative for markers for hepatitis B and HIV, received 20 microg of the vaccine intramuscularly at 0, 1 and 2 months. Forty-three (53%) seroconverted at one month after dose 1; of these, 26% were seroprotected (anti-HBs> 10 mIU/mL). Seroprotection at one month after doses 2 and 3 was 99% and 100%, respectively. Geometric mean titres of anti-HBs in subjects who seroconverted were 11 (range 2-366), 266 (8-7469) and 2246 (102-23680) mIU/mL, respectively. One subject developed urticarial rash after the second dose; there was no other adverse event. We conclude that this vaccine is safe and efficacious, providing significant protection even after two doses.
