Study on early intervention with ACE inhibitor in myocardical infarction and short term outcome.

The present study was carried out on 100 patients with acute myocardial infarction (AMI) being treated with angiotensin converting enzyme (ACE) inhibitor and another 80 patients with conventional treatment but without ACE inhibitor during the period from May 1, 1995 to August 7, 1996 in Medical College, Calcutta. Clinical and other laboratory investigations including echocardiographic parameters were noted and recorded meticulously within 24-48 hours after AMI and repeated at 4th week. The present study based on non-invasive methods other than haemodynamic methods has shown that the echocardiographic assessment of left ventricular functional parameters after 4 weeks of ACE inhibitor therapy (n = 100) were better in treated group in comparison to control group without ACE inhibitor (n = 80) and the difference was statistically significant at 99% level of confidence. Overall mortality was 4% in ACE inhibitor group and 8.75% in the control group. This short term study with early intervention with ACE inhibitor within 48 hours of AMI has shown statistically significant evidence of beneficial effect of ACE inhibitor in improving the ventricular functional parameters and also reducing short term mortality from cardiac cause within 4 weeks compared to the group not receiving ACE inhibitors.

Etiology based prevalence of Budd-Chiari syndrome in eastern India.

BACKGROUND: Diagnosis of Budd-Chiari syndrome (BCS) is often missed unless its possibility has been kept in mind. Obstruction of inferior vena cava (IVC) is reportedly the most frequent cause of BCS in Afro-Asian variety. AIM: An attempt was made to classify BCS (in an eastern Indian population) etiopathologically. PATIENTS AND METHODS: Thirty consecutive cases of BCS presenting over a period of five years were included. Following a thorough physical examination, necessary investigations (including coagulation profile, ultrasonography (with Doppler study) of hepatobiliary tract, hepatic vein and IVC angiography (n = 22) and liver biopsy (n = 26, including autopsy in two cases) were performed. RESULTS: Mean age at presentation was 32.7 +/- 10.36 years (range 12-60 years) with M:F = 21:9. Clinical presentations included, hepatomegaly in 28 (93.3%), ascites in 27 (90%), splenomegaly in 15 (50%), pain in abdomen in 26 (86.6%), jaundice in 10 (33.3%), back veins in 20 (66.6%) and gastrointestinal bleeding in three (10%) cases. Amongst the total of 30 patients, four, six and 20 cases presented as fulminant, acute and chronic BCS respectively. Twenty four cases of BCS could be diagnosed by ultrasonography alone, while the remainder required angiography for diagnosis. IVC and hepatic vein angiography revealed membranous obstruction in nine, partial stricture of IVC in six, and IVC and/or hepatic vein block in others. The etiopathological nature in 30 cases were as follows: idiopathic membranous obstruction in nine (30%), hepatocellular carcinoma in six (20%), idiopathic stricture in six (20%) cases and one case (3.3%) each of the following: cholangiocarcinoma, renal cell carcinoma, chronic pancreatitis, hydatid cyst in liver, protein S deficiency, oral contraceptive use, nephrotic syndrome (with antithrombin III deficiency), polycythemia rubra vera and chronic lymphatic leukemia. CONCLUSION: Idiopathic membranous obstruction and stricture of IVC are the commonest cause of BCS in the eastern part of India. Hepatocellular carcinoma is also a common cause, presenting in the fulminant form. Ultrasonography may be a helpful screening test for BCS, but IVC and hepatic vein catheterisation is essential for a complete work up of these patients.

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.

Epidemiology of peptic ulcer in north Bengal, India.

A retrospective analysis of hospital records of inpatients of Medicine department of North Bengal Medical College and Hospital during the period between 1988-90 revealed that 6.2% of all medical admissions were on account of peptic ulcer and or acute gastritis. Duodenal ulcer was prevalent accounting for more than 50% of the cases of peptic ulcer and acute gastritis. Duodenal ulcer was more common in the working age groups (> 21 years) among males and more than 31 yrs among females. Gastric ulcer was more common among older age groups. In respect to ethnicity, Bengali speaking hindus showed high probability for gastric ulcers in both sexes. The probability for duodenal ulcer was within confidence limits among all social groups.

Evaluation of stroke patients with reference to CT scan findings.

Eighty patients suffering from stroke were studied on the setting of clinical and computerised tomography (CT) scan findings and were followed up to 6 months. Even though some of the clinical and CT scan findings are found to be important in prediction of outcome of stroke patients, clinical assessment appears to be more important.

Incidence of hepatitis B virus (HBV) infection amongst clinically diagnosed acute viral hepatitis cases and relative risk of development of HBV infection in high risk groups in Calcutta.

The present study revealed that 30.5% of acute infective hepatitis were due to the infection of Hepatitis B virus (HBV) however, 8% controls also showed HBV positivity. The possible route of infection of HBV in our country were Parenteral in 51.9%, Sexual in 24% and Unidentified in 24.1% cases. HBV marker positivity was 45.5% amongst health care workers 33.3% in recipients of multiple blood and blood product transfusion, 25% in sexual partners and their children, 20% in S.T.D. clinic attendants and 10% in patients on haemodialysis.

A study of mycetoma in eastern India.

Forty consecutive cases of mycetoma were studied with respect to clinico-epidemiological, histopathological and radiological features. The age of the patients ranged from 17 to 57 years mean being 32.4 +/- 8.68. The disease was equally distributed amongst the sexes. Most of the patients had a rural background and the disease occurred mainly among farmers and housewives. Actinomycetes (32 cases. 80%) were found to be the main pathogenic organism and Eumycetes in 4 cases (20%) only. Clinical features were more or less the same irrespective of the aetiologic agent, consisting of local swelling with discharging sinuses. History of trauma was present in only 20% cases and 80% were incidental. Foot (28/40 i.e. 70%) was the commonest site of infection. Radiological bony involvement was detected in 14 out of 18 cases examined (38.88%). Out of the 32 radiographed patients of actinomyetoma 10(31.25%) showed bony involvement whereas all the four. Eumycetoma cases radiographed, had bony involvement. The notable bony changes were sclerosis, erosions, periosteal thickening and osteoporosis.

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.
