Item Clinical, angiographic and histopathological predictors of restenosis after directional coronary atherectomy.(1995-05-01) Petkar, S; Gambhir, D S; Trehan, V; Nair, M; Gondal, R; Malhotra, V; Khalilullah, MOut of 127 directional coronary atherectomy (DCA) procedures done in our laboratory, there were 81 patients who had completed a minimum of six months of follow-up. To study the factors predisposing restenosis after successful DCA, we analysed the clinical and angiographic profile of the patients and the histopathological findings of the excised tissue in 44 patients whose complete follow-up data was available with us. The indication of DCA was an extremely eccentric significant stenosis located in the proximal or midsegment of a large vessel (> or = 3 mm size) in 97 percent of the cases. Angiographic restenosis, defined as more than 50 percent luminal diameter stenosis was absent in 24 (54.5%, Group A) and present in 20 (45.5%, Group B) patients. On univariate analysis, the factors which predisposed to restenosis were: (i) left anterior descending location, (ii) longer lesion length (9.6 +/- 3.1 mm vs 5.2 +/- 1.6, p < 0.01) and (iii) greater post-procedure residual luminal diameter stenosis (13.1 +/- 10.8% vs 4.3 +/- 6%, p < 0.01). No significant difference was found between the two groups for other variables like unstable angina, the location and the morphological characteristics of the lesion and the ratio of the vessel diameter to the size of the Atherocath. Histopathological examination of the retrieved tissue revealed the presence of media with or without external elastic lamina in 8 (33%) patients in Group A--without restenosis compared to only 1 (5%) patients in Group B--with restenosis (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)Item Dual exposure and repair technique for ruptured aneurysms of aortic sinus of Valsalva.(1994-01-01) Gupta, R; Khanna, S K; Akhtar, M; Gupta, B K; Nigam, M; Banerjee, A; Satsangi, D K; Gondal, R; Arora, R; Sethi, K KThirteen patients with ruptured sinus of Valsalva aneurysm have been operated over a 3-1/2 year period. Right coronary sinus was predominantly involved and right ventricle was the most common site of rupture. Early surgery was performed in all cases. Both aorta and chamber of entry were explored for effective repair. Main repair was always done in the chamber of rupture either with a patch or interrupted pledgeted sutures followed by assessment at either end. Subannular ventricular septal defects in three cases were closed with a common patch with additional fixation in the middle at the aortic annulus to prevent aortic leak into the left ventricle. Three patients needed aortic valve replacement for gross aortic incompetence. Postoperative echocardiographic study revealed uniformly excellent results with good aortic valve or prosthetic function. One patient developed fatal pulmonary embolism two weeks following surgery. All other surviving patients are doing well and are in NYHA class I. We recommend dual exposure and repair technique for the repair of ruptured sinus of Valsalva aneurysms for optimal results.Item Early gastric carcinoma.(1986-01-01) Gondal, R; Malik, R; Malhotra, V; Beohar, P C; Kumar, NItem Endomyocardial biopsy--its evaluation in cardiac disorders.(1993-01-01) Malhotra, V; Tatke, M; Gondal, R; Prasad, M; Sethi, K K; Arora, R; Kaul, U A; Khalilullah, MEndomyocardial biopsies (EMBs) of 47 patients with various cardiac disorders were analysed. Clinically 26 patients were diagnosed as having dilated cardiomyopathy (DCM), 9 myocarditis, six restrictive heart disease and six as Duchenne muscular dystrophy. EMB showed normal histological picture in six cases of DCM and findings consistent with DCM in rest of the twenty cases. None of these biopsies showed evidence of myocarditis. Diagnosis of myocarditis could be confirmed on EMB only in three out of nine clinically diagnosed cases. Cases with restrictive heart disease showed normal biopsy in two, infarction in one, findings consistent with endomyocardial fibrosis in one and amyloidosis in two cases. EMB on six cases of Duchenne muscular dystrophy showed nonspecific histological changes. To conclude, in this series, cases of DCM did not show evidence of underlying myocarditis in endomyocardial biopsies.Item Gamma and immuno globulins in healthy Indian children.(1980-07-01) Malik, G B; Gondal, R; Yadav, RItem Gastrooesophageal reflux in infants and children in north India.(2001-04-13) De, S; Rajeshwari, K; Kalra, K K; Gondal, R; Malhotra, V; Mittal, S KOBJECTIVES: To assess the prevalence of gastrooesophageal reflux disease (GERD) as suggested by the symptom profile in babies ranging in age from 1 month to 2 years. METHODS: Six hundred and two babies were recruited from the well baby clinic for hospital delivered babies and from the childrens OPD of a tertiary care hospital. Children with acute severe illness needing hospitalization were excluded from the study. The primary care taker of each baby was interviewed using a questionnaire (IGERQ) designed by Orenstein et al and the I-GERD score obtained was used to assess for likelyhood of GERD. Upper gastrointestinal (GI) endoscopy was carried out and an oesophageal biopsy was taken in clinically suspected cases of GERD (IGERD > 5). RESULTS: Sixty one (10%) of the 602 subjects had an I-GERD score of > 5 suggestive of GERD. Regurgitation was present in 56 of these 61 subjects and also in 106 of the 541 normal subjects. 112 of 205 infants aged 1-6 months had regurgitation and 25 (22.2%) of these regurgitant infants had a score suggestive of GERD. Only 30 of the 202 infants aged 6-12 months and 20 of the 195 babies aged 12-24 months had regurgitation, however 14 of the 30 (46.5%) and 17 of the 20 (85%) regurgitant babies had an I-GERD score suggestive of GERD. Upper GI endoscopy was carried out in 31 babies with a score > 5 and endoscopic oesophagitis was detected in 16 (51.6%). Oesophageal biopsies were taken in 25 of these cases and showed histological evidence of reflux oesophagitis in 23 (92%). CONCLUSION: GERD is fairly common under 2 years of age as observed by symptom evaluation using the I-GERD score. Regurgitation when present beyond 6 months of age with no other identifiable cause needs evaluation. Upper GI endoscopy and oesophageal biopsy is a useful means of demonstrating reflux oesophagitis in babies with a symptom profile suggestive of GERD.Item Glycogen storage disease type III.(1994-10-01) Kapoor, S; Kumar, P S; Mathur, N B; Gondal, R; Khalil, AItem Hepatocellular carcinoma presenting as soft tissue mass in gluteal region.(2000-07-05) Rana, S S; Rajan, A; Arora, A; Madan, K; Das, K; Gondal, R; Kumar, S; Kar, PItem Histological and immunological analysis of gastric and intestinal lymphomas.(1992-01-01) Tatke, M; Malhotra, V; Sankaran, V; Malik, R; Gondal, R; Kumar, N; Chaudhary, AImmunophenotyping of 28 gastrointestinal non-Hodgkin's lymphomas was done using specific antibodies. Twenty six of these were successfully classified using this technique.Item Histological comparison of chronic hepatitis B and C in an Indian population.(2000-01-03) Malhotra, V; Sakhuja, P; Gondal, R; Sarin, S K; Siddhu, M; Dutt, NMany studies have shown that steatosis, lymphoid aggregates or follicles and bile duct injury on histology are more consistently associated with chronic hepatitis C than chronic hepatitis B. We compared liver biopsies of 30 patients of chronic hepatitis B with an equal number of age matched patients with chronic hepatitis C. Steatosis, lymphoid aggregates or follicles and bile duct injury were noted in 66.6%, 36.6% and 26.6% cases respectively of chronic hepatitis B as compared to 70%, 33.3% and 30% cases respectively of chronic hepatitis C. Thus none of the features were considered distinctive of HCV infection.Item Histoplasmosis of the liver: a rare case.(2002-04-14) Mazhari, N J; Sakhuja, P; Malhotra, V; Gondal, R; Puri, JA 39 year old male presented with history of fever and jaundice for 3 months. A liver biopsy showed numerous ovoid fungal bodies around 5 mm in size in the macrophages and Kupffer cells. A diagnosis of hepatic histoplasmosis was made which is an uncommon entity in our country.Item Immunological alterations following open heart surgery.(1991-01-01) Tatke, M; Khanna, S K; Malhotra, V; Thankamani, T R; Tempe, D K; Malik, R; Gondal, R; Nigam, MImmunological changes in thirty patients undergoing various cardiac surgical procedures (twenty patients undergoing open heart surgery with either the bubble or the membrane oxygenator and ten patients undergoing closed surgical procedures) were studied. There was an activation of suppressor T cells and secretion of lymphokines in patients undergoing open heart surgery with activation of the classical complement pathway. The immunological alterations were similar in all patients irrespective of the type of oxygenator used.Item Intestinal metaplasia--its association with gastric cancer.(1995-10-01) Malhotra, V; Tatke, M; Gondal, R; Kumar, N; Broor, S LEndoscopic gastric biopsies from 230 patients and post gastrectomy specimens of 18 patients were evaluated for the presence of intestinal metaplasia (IM) and its association with the gastric lesions. There were a total of 78 malignant and 170 benign lesions. IM was present in 53% of patients with gastric carcinoma (GC) and in 10.6% with benign lesions of the stomach. The IM in association with GC was of type 1 (Small Intestinal) in 58.8%; type II (mixed gastric and small intestinal) in 11.8% and type III (Colonic) in 29.4%. In patients with benign lesions the IM was predominantly of type I (94.5%) except in 1 patient who had type III metaplasia. Our findings indicate that type III IM was significantly more frequent in patient with GC than with benign lesions (29.4% Vs 5.5%; p < .005). Therefore we conclude that patients with type III IM should be kept on surveillance for GC.Item Intrapericardial teratoma masquerading as pyopericardium.(2001-04-01) Dhir, V; Gupta, V; Gondal, R; Banerjee, AA 10-year-old boy was admitted with cardiac tamponade. Initial pericardiocentasis yielded pus. A subxiphoid tube-pericardiostomy was done and thick, purulent material was drained out. Subsequently, pericardiectomy was undertaken as features of pericardial constriction persisted. At surgery, however, an intrapericardial mass was discovered. Successful excision was performed and the patient made an uneventful recovery. Histopathology of the mass revealed features of an intrapericardial teratoma. Rarity of the lesion, and a hitherto unreported mode of presentation make this case worthy of documentation.Item Malignant carcinoid of the thymus.(1990-10-01) Malik, R; Malhotra, V; Gondal, R; Tatke, M; Khanna, S KItem Medulloblastoma--a histomorphological profile.(1985-03-01) Malik, R; Malhotra, V; Beohar, P C; Gondal, R; Prakash, B; Malik, T KItem Meningiomas--a histomorphological study.(1984-11-01) Malhotra, V; Malik, R; Beohar, P G; Gondal, R; Prakash, BItem Myoepithelioma. A case report.(2001-01-10) Saraf, S; Gondal, R; Verma, MA rare case of oral myoepithelioma is reported. The tumour was composed of plasmacytoid type of myoepithelial cells. These plasmacytoid cells or hyaline cells exhibited a diffuse positivity for pancytokeratin, S-100 and vimentin in their cytoplasm. Studies have to be performed in order to find out whether the myoepithelial cells M.E. of plasmacytoid type are true M.E. cells of not.Item Nucleolar organiser regions in different colonic epithelia.(1997-01-01) Jain, R; Malhotra, V; Gondal, R; Tatke, M; Vij, J CThe argyrophilic technique (AgNOR) was applied to paraffin sections of 10 acute self-limited colitis, 15 ulcerative colitis (UC), 5 ulcerative colitis with indefinite dysplastic change, 10 adenomatous polyps, 20 colorectal adenocarcinomas and 10 normal colorectal mucosa. The mean number of nucleolar organiser regions (NORs) per nucleus ranged between 1.62-2.00 (95% CI 1.77-1.93) for normal colon, 2.47-3.80 (95% CI 2.71-3.21) for acute colitis, 1.66-2.75 (95% CI 2.13-2.44) for UC, 3.60-4.00 (95% CI 3.67-3.94) for UC with indefinite dysplasia, 3.00-4.04 (95% CI 3.41-3.81) for adenomatous polyps and 3.59-6.70 (95% CI 4.04-4.72) for colorectal adenocarcinoma. The differences observed were statistically significant. There was a significant difference of AgNOR counts between adenomatous polyp and UC with indefinite dysplasia in comparison to those observed in regenerative epithelium of acute colitis and UC without dysplasia. Hence the technique may be used as an adjunct to routine histology for delineating dysplastic changes in colonic epithelium.Item Primary amyloidosis.(1986-01-01) Malhotra, V; Malik, R; Beohar, P C; Gondal, R; Anand, B S
