Tuberous Xanthoma in Diabetes Mellitus: A Case Report.

Xanthoma is a deposition of cholesterol in the soft tissues. It is an uncommon presentation of hypercholesterolemia and/or diabetes mellitus (DM). We are reporting a case of 60-year-old female who presented with multiple xanthomas over extensor tendons of both hands and elbows. Her investigations revealed raised triglycerides, very high plasma cholesterol, very lowdensity lipoprotein (VLDL) and low-density lipoprotein (LDL) levels. Fasting and postprandial sugar levels were also increased. A work-up for cardiovascular involvement was normal and biopsy from one of the nodules showed the xanthoma cells.

Anaphylactic Shock: A Rare Presentation of Phenytoin Drug Reaction.

The adverse effects of phenytoin are well-documented in literature. We describe a case of severe anaphylactic shock following intravenous administration of phenytoin, a rarely described and known entity.

Upper GI endoscopy showed esophageal varices. She was treated with variceal band ligation and is well on folic acid supplements and propranolol.

Central retinal artery occlusion: an unusual complication of snakebite

Snakebites are endemic in some parts of India, being associated with a number of complications. Ocular disturbances are rare, except for injury to the cornea or conjunctiva when the eye is directly exposed to the venom. In this work, we present a case of central retinal artery occlusion caused by snakebite.(AU)

Leptospirosis--a case report.

Outbreaks of Leptospirosis have been reported from various parts of India including Maharashtra. We report a case of leptospirosis from Wardha District, Maharashtra from where the disease has not been reported so far.

Role of oxygen free radicals in causing endothelial damage in acute myocardial infarction.

OBJECTIVES: This work was done in order to study the oxidant and anti-oxidant status in a disease resulting from endothelial injury. The disease selected for study was acute myocardial infarction. METHODS: Sixty patients of acute myocardial infarction were selected after being diagnosed in accordance to the guidelines laid down by the WHO. Thirty subjects were included as controls. Plasma levels of certain markers of oxidative stress and anti oxidant activity were measured in all the subjects. Malonaldehyde (MDA) and nitrite (NO2) were measured as markers of free radical mediated endothelial injury, and superoxide dismutase (SOD) enzyme as an indicator of antioxidant activity. RESULTS: It was found that the plasma levels of MDA and nitrite were significantly elevated in the patients of acute myocardial infarction compared to the control group (7.29 +/- 3.28 v/s 4.57 +/- 0.63 nmol/ml and 12.85 +/- 8.71 v/s 0.97 +/- 0.25 microM respectively), thereby indicating that oxygen free radicals cause endothelial damage in them. The superoxide dismutase levels were also found to be elevated in these patients (5.57 +/- 1.47 v/s 3.91 +/- 0.66 U/ml). CONCLUSION: These results indicate that acute myocardial infarction is a state of enhanced free radical activity, which causes endothelial damage. The elevated SOD levels may imply that the body attempts to combat this oxidative stress by raising it's level of anti-oxidants.

Spontaneous bacterial peritonitis in liver cirrhosis with ascites.

OBJECTIVE: The study was designed to elucidate the correlation of spontaneous bacterial peritonitis (SBP) with aetiology of liver cirrhosis, overall mortality, ascitic fluid and systemic microbial infections. METHODS: Sixty three patients with cirrhosis of the liver were included in this study. These patients were diagnosed on the basis of clinical evaluation, biochemical investigation, ultrasonography, ascitic fluid examination for protein, cells, pH, and bacterial culture. RESULTS: SBP developed in 22 (34.92%) patients of cirrhosis. Culture positive SBP was present in 18 (81.81%) and culture negative neutrocytic ascitis (CNNA) in 4 (18.18%). In the culture positive group, 14 (77.7%) patients had monomicrobial bacterascites (MNB), the commonest organism being coagulase positive Staphylococcus aureus eight (44.44%) followed by E. coli (22.22%). Only 4 (22.22%) had infection by more than one organism. Direct bed side inoculation of ascitic fluid into blood culture bottle was a better method for bacterial yield than the conventional method of ascitic fluid culture (81.8% vs. 18.2%). Only 22.8% patients with SBP had ascitic fluid protein less than 1 gm%, ascitic fluid pH < 7.3 and polymorphonuclear cell count > 250/cmm. CONCLUSION: Spontaneous bacterial peritonitis is common complication in Child Pugh class C cirrhosis. Alcoholic cirrhosis with SBP carries high mortality than their non-alcoholic group. The most common organisms isolated were coagulase positive Staphylococcus aureus followed by E. coli.

Accuracy of clinical manoeuvres in detection of minimal ascites.

A study was conducted to assess the clinical accuracy of various clinical manoeuvres and signs used routinely for detection of ascites. Sixty-six patients admitted in medical ward of a teaching hospital after initial screening by a consultant were selected. Exclusion criteria were; cases with previous history of ascites, who had undergone paracentesis in the recent past or with evidence of ascites from history. Another clinician blind to history and clinical details assessed the presence of ascites by the selected methods a sonographer blind of clinical and historical details assessed the cases for presence of ascitic fluid. The clinical findings were compared using ultrasonographic (USG) findings as gold standard. Ascites was detected in 35 patients by USG. the mean weight and abdominal girth of study subjects with or without ascites were comparable (p > 0.05). Sensitivity of auscultatory percussion was highest (65.7%) followed by flank dullness (57.1%) and least for fluid wave sign (20.0%). Fluid wave sign had the highest specificity (100%). We found that none of the manoeuvres studied for detection of ascites was both highly sensitive and specific. However, auscultatory percussion could be useful for initial screening of patients to detect ascites.

The prevalence of hypertension in rural population around Sevagram.

To detect the prevalence of hypertension in an asymptomatic rural community from Central India, we screened 4045 subjects (2247 men and 1798 women) aged 20 and beyond. The prevalence of hypertension was 34.12 per thousand population, being higher in women (40.60 per thousand) than in men (28.92 per thousand). Level of physical activity, economic status, smoking and body mass index showed real association with hypertension.

False positive ECG and coronary heart disease.

In 1983, we carried out a cross-sectional, rural community based study and highlighted an abysmally low prevalence of probable coronary heart disease in resting electrocardiogram. A seven year follow-up (1983-1990) of 179 suspects showed no morbidity or mortality from coronary heart disease. Eighty one out of 98 suspects tested negative on a symptom limited maximal exercise test. Though seventeen suspects had an asymptomatic exercise-induced ST depression (> 1.0 mm) their haemodynamic response to exercise and effort tolerance was excellent. Of the twelve subjects who took a repeat exercise test six months later, eleven failed to show ST depression on exercise. We attribute the false positivity of exercise test and its poor reproducibility to labile electrocardiographic changes unmasked by exercise.

M-mode echocardiographic diagnosis of left ventricular hypertrophy.

To assess the utility of various primary and derived M-Mode Echocardiographic parameters for the purpose of defining left ventricular hypertrophy (LVH), 74 subjects with LVH were subjected to M-mode echocardiographic examination. It was concluded that except for cross sectional area, the other echocardiographic parameters performed too poorly to be of any clinical utility for defining LVH by echocardiography.

Left ventricular M-mode echocardiographic measurements of Indian population.

The left ventricular dimensions of 506 normal healthy subjects (men = 317, women = 189) in the age group of 17 to 80 years were measured echocardiographically. The measurements were found to differ significantly from the western data. A separate limit for left ventricular echocardiographic parameter for the normal Indian population was established.

Evaluation of clinical variables as predicators of left ventricular function in acute myocardial infarction.

In 43 rural patients, all survivors of acute Myocardial infarction, left ventricular function was studied by 2-D echocardiography and evaluated in relation to 18 clinical predictors of left ventricular function. The mean left ventricular ejection fraction (LVEF) was 41.53 +/- 12.92% as compared to 70.02 +/- 7.02% in 506 healthy controls. LVEF was dichotomised at < 40% (n = 24) and > 40% (n = 19). Out of various clinical variables analysed following were found to be strong predictors of low LVEF. S3 gallop (p < 0.001) pulmonary rates (p < 0.001); Creatine phosphokinase > 200 I.U. (p < 0.001); Cardiomegaly on X-ray (p < 0.001); pulmonary congestion on chest X-ray (p < 0.001); and proportional pulse pressure (p < 0.001). There was a stepwise decline in the LVEF for each additional clinical variable. The over all predictive accuracy was 90%. It is concluded that readily obtainable clinical variables provide a useful bedside method of estimating LVEF after acute myocardial infarction.

Left ventricular mass by M-mode echocardiography.

A comparison of various M-mode echocardiographic methods for assessment of left ventricular mass (LVM) was done in 21 subjects. The anatomical LVM was taken as Standard; it varied from 64.55 to 341.82 g. Of the six different M-mode echo methods compared, the method of Devereux and Reichek (1977) was found to correlate best with anatomical LVM (r = 0.99; SD = 49.54). By this method LVM = 1.4 [(LVIDd + LVPWTd + IVSTd)3 - (LVIDd)3] - 14 g.

Left ventricular muscle mass by echocardiography: methodology.

The limitations of electrocardiography for diagnosing left ventricular hypertrophy (LVH), due to unacceptable accuracy and lack of serial quantifications, are well known. The use of angiocardiography for LVH assessment is invasive, hazardous and costly. Echocardiography provides an excellent method of estimation of left ventricular muscle mass, which is simple, non-hazardous, accurate and reproducible.
