A comparative study of balloon mitral valvuloplasty and closed mitral commissurotomy in patients with rheumatic mitral stenosis.

Rheumatic mitral stenosis is frequently encountered in our country. It affects younger population and is a major cause of morbidity Mitral valvotomy is the definitive therapy for this disease and can be achieved by closed mitral commissurotomy (CMC), open mitral commissurotomy (OMC) or by percutaneous transluminal mitral valvuloplasty (PTMV). Compared to CMC, PTMV is less invasive but more expensive at this moment. With the reduction of cost, PTMV may become the procedure of choice for the treatment of rheumatic mitral stenosis in future.

Gastroduodenal mucosa in peptic ulcer: endoscopic and histological assessment.

This study aimed to assess the prevalence of endoscopic and histological gastroduodenitis as well as helicobacter-like organisms in patients with peptic ulcer. After diagnostic endoscopy, gastroduodenal biopsy specimens were taken from thirty patients (n = 30) with clinical and endoscopic diagnosis of peptic ulcer (duodenal ulcer = 25, gastric ulcer = 5). Endoscopic gastroduodenitis occurred in 18 patients (60%). Histological gastritis was detected in the gastric body or antrum in 25 (83%) and duodenitis in 17 (57%) patients. There was significant correlation between endoscopic and histological gastritis (p < 0.05). Helicobacter-like organisms occurred in 73% of the patients with peptic ulcer and in 88% of the antral biopsy specimens showing antral gastritis. Presence of helicobacter-like organisms was in particular associated with acute on chronic gastritis compared to chronic gastritis (p < 0.01). Moreover the patients with gastritis were found to belong to the older age group and 81.8% had blood group O +ve (p < 0.01 and p < 0.05 respectively). We conclude that presence of helicobacter-like organisms in patients with peptic ulcer is significantly associated with acute on chronic gastritis.
