RESUMEN
Rotavirus is a leading cause of severe pediatric diarrhea worldwide, with about 199,000 childhood deaths in 2015, of which 90% in low-income countries. India alone accounts for 22% of the global rotavirus gastroenteritis (RVGE)-related deaths among children below 5 years of age. The World Health Organization recommends introducing rotavirus vaccines (RVVs) as a priority in developing countries where high rates of RVGE are observed. To have the desired impact, RVV should be administered the earliest possible, ideally before the first episode of RVGE. In India, four RVVs are available for use in infants ?6 weeks of age: the single-strain, two-dose, live-attenuated human RVV Rotarix; the five-strain, three-dose, human-bovine reassortant RVV Rotateq; the single-strain, three-dose, naturally reassortant human-bovine RVV Rotavac; and the five-strain, three-dose, human-bovine RVV Rotasiil; all of them proven to be efficacious and well tolerated. Whereas Rotarix and Rotateq have shown high efficacy/effectiveness against severe RVGE in developed countries (?90%), they have been observed to be lower in developing countries (~40%–70%). Rotavac and Rotasiil have shown similar efficacy in low-income settings, but further studies are needed to assess their effectiveness. Rotarix and Rotateq have not shown increased intussusception (IS) risk in clinical trials. Postmarketing surveillances were able to show a very tiny increased risk of IS after the first dose of vaccine, but the extensive benefits of rotavirus vaccination far outweigh the low-level risk of IS. In India, where the disease is a major problem and occurs in very early months of life, RVVs should have high coverage and vaccination schedule should be completed as early as possible (?6 weeks of age) to maximize the vaccine impact.
RESUMEN
Background: Ageing is a natural phenomenon associated with physiological and functional decline in the body, which makes elderly people vulnerable to malnutrition and age related morbidity. Hence, this study was undertaken to assess nutritional status and morbidity pattern of urban elderly. Aims & Objectives: To assess the nutritional status and the morbidity status of urban elderly. Material and methods: A community based cross-sectional study was conducted among the urban elderly in Hyderabad. A total of 261 individuals of ≥60 years were recruited for this study. Anthropometric measurements were measured to assess nutritional status. Pre-tested questionnaire was used to collect information on demographic particulars and self-reported morbidity profile. Data are presented as mean ± standard error and significance level was considered at p < 0.05. Result: The mean height and weight were 160.49 Cm ±0.55 and 66.59 Kg ± 0.68, respectively while the mean BMI was 25.83 Kg/m2 ± 0.22. The prevalence of overweight and obesity among urban elderly was 46.0% and 31.4 %, respectively. The prevalence of central and truncal obesity was 60.1% and 84.6% respectively. The prevalence of morbidities such as poor vision, hypertension, joint pains, diabetes, cataract and hyperacidity was 86.1%, 63.2%, 49.4%, 48.3%, 36% and 32.2% respectively. There was a significant (p<0.05) gender difference among BMI, central obesity, CVDs, joint pains and osteoarthritis. Conclusion: In general, the prevalence of NCDs such as obesity, hypertension and diabetes are significant public health concern among urban elderly. Therefore, primordial and primary preventive measures should be adopted during adolescence and early adulthood for the prevention and control of NCDs during the period of ageing
RESUMEN
22 year old woman with no previous heart disease history, presented with progressive worsening of right heart failure symptoms due to severe tricuspid valve regurgitation which had become refractory to medical management. Echocardiogram revealed probable rare case of dysplastic tricuspid valve with large calcified mobile masses attached to leaflets. Calcified masses were thought to be due to healed vegetations from silent infective endocarditis of abnormal tricuspid valve which she had suffered in the past. There were no known acquired causes of tricuspid valve endocarditis. She had successfully undergone tricuspid valve replacement with bio-prosthetic valve along with a right atrial reduction surgery after which her heart failure symptoms improved markedly.

A total of 23 clinical isolates (15 Escherichia coli and 8 Klebsiella pneumoniae), resistant to cefotaxime and ceftazidime recovered during 2002 and 2003, were investigated for production of CTX-M extended spectrum beta-lactamase (ESBL) by phenotypic and molecular methods. The presence of ESBL was tested by NCCLS phenotypic confirmatory test using cephalosporin/clavulanate combination discs and E-test ESBL strips. Determination of MIC of cefotaxime and ceftazidime was done with and without the presence of clavulanic acid by agar dilution technique. Polymerase chain reaction revealed the presence of CTX-M type ESBLs in 19 isolates. Further sequencing resulted in identification of CTX-M-15 ESBLs. This is the first report identifying CTX-M type ESBL from clinical isolates of E. coli and K. pneumoniae from a tertiary care hospital in south India.

AIMS AND OBJECTIVES: Idiopathic Pulmonary Arterial Hypertension (IPAH) is a serious disorder of unknown etiology with limited therapeutic options. Sildenafil has been shown to decrease symptoms, improve hemodynamics and quality of life. Its impact on survival is uncertain. We studied the efficacy of sildenafil in improving survival in patients with IPAH. METHODS AND RESULTS: Data on survival of patients with IPAH was collected from prospectively maintained registry at our hospital from January 1999 to December 2005. Thirty nine patients who were treated with conventional therapy including digoxin, diuretics, anticoagulants and calcium channel blockers prior to January 2001 served as historical controls (control group). One hundred and thirty nine patients received sildenafil additionally from January 2001 (sildenafil group). All patients in sildenafil group showed improvement in symptoms. Survival of patients in sildenafil group was significantly better compared to historical controls receiving only conventional therapy. It was 89%, 43% and 19% in the control group Vs 93%, 75% and 54% in the sildenafil group at the end of 1, 3 and 5 years respectively (P Value=0.0002). Sildenafil was well tolerated and none of the patients had to discontinue the treatment. CONCLUSION: Sildenafil when added to conventional therapy improves symptoms as well as survival significantly compared to conventional therapy alone. Further randomized controlled trials are needed to evaluate its impact on survival when used either alone or in combination with other drugs.

BACKGROUND: Banana leaf is used in many centers in India during the care of patients with toxic epidermal necrolysis (TEN) and other extensive blistering disorders. Sepsis is an important cause of death in TEN patients and use of banana leaf may be a source of such infection. AIMS: We conducted this study to detect the bacterial flora of the banana leaf and to examine various methods of rendering the leaf aseptic. METHODS: Five pieces of banana leaf, 2 x 2 cm in size, were cultured separately in blood agar as follows: One piece was heated over a flame and one was soaked in boiling water and one was autoclaved. Methylated spirit was applied over one piece and ignited. One piece was placed on the media, 'as is.' The Petri dishes were incubated examined after 48 h. RESULTS: All the pieces except the autoclaved specimen of the leaf grew coagulase-negative staphylococci (CONS) when aseptic precautions were not maintained and aerobic spore bearers when all aseptic measures were subsequently instituted during the procedure. CONCLUSION: We recommend measures to prevent possible transmission of bacterial infection by the leaf. Autoclaved and aseptically handled banana leaves may be used to reduce chance of infection in the treatment of TEN.

BACKGROUND, Drug-eluting stents have enabled considerable reduction in restenosis in patients subjected to angioplasty. However, in view of high cost of drug-eluting stents, efforts to develop medicated stents at reduced cost using alternative polymers in Indian setting are imperative. Hence a multi-center study was undertaken to evaluate the safety and efficacy of the indigenously developed paclitaxel-eluting RELEASE-T stent. METHODS, The study included 100 patients (male:86, Female:14) who were undergoing angioplasty for various indications at four centres viz. Delhi, Hyderabad, Pune and Warangal. The age range was 29 - 76 years; 37 patients were diabetic. All patients were pre-treated with aspirin 150-325 mg plus clopidogrel 75 mg daily four days before procedure or clopidogrel alone. Aspirin was continued indefinitely. RESULTS, Direct stenting ws done in majority of patients. One patient, in whom stent could not be delivered, received only baloon angioplasty. Sixty-four patients had stenting of left anterior descending artery. The stent diameter ranged from 2.5 to 3.5 mm, and the length, 15 to 20 mm. All patients were followed up at 1,3 and 6 months. There was two deaths: one had subacute thrombosis on both stents, and the other (who was HIV positive) had sudden cardiac death. The 6-month rate of major adverse cardiac events was 4% and target lesion revascularization rate ws 2%. CONCLUSION, This ulti-locational study brings out that the use of indigenously developed paclitaxel-eluting stent is safe and clinically efficacious.

Non-surgical transpericardial approach for catheter-based epicardial radiofrequency ablation of post-infarction left ventricular tachycardia has been described as an alternative and additive procedure to standard endocardial technique for delivery of radiofrequency energy in difficult situations. We report our initial experience with this approach in three patients of post-infarction recurrent ventricular tachycardia, refactory to multiple antiarrhythmic drugs. Ablation was successful in terminating the tachycardia in two and in modifying the circuit to be amenable for control with single antiarrhythmic drug in one patient. There were no serious acute or long-term complications related to the procedure. Epicardial approach is an effective and safe adjunct to standard endocardial ablative technique for patients of post-infarction ventricular tachycardia.

The congenital form of His bundle tachycardia is an uncommon pediatric arrhythmia. We report the case of a 7-year-old child with tachycardiomyopathy. The incessant arrhythmia, detected in infancy, was resistant to amiodarone and beta-blockers. During electrophysiologic study, the tachycardia converted to sinus rhythm with intravenous adenosine and diltiazem. Subsequently, the child is maintaining sinus rhythm on oral verapamil. Calcium-channel blockers should be considered for the treatment of this arrhythmia, which is often resistant to multiple antiarrhythmic drugs.

Percutaneous transluminal coronary angioplasty with stent implantation is a universally accepted therapeutic option for patients with coronary artery disease. Since introduction in 1977, angioplasty techniques have been greatly improved; the availability of better hardware, greater operator experience, better patient selection and the judicious use of adjunctive therapy like heparin, clopidogrel, platelet receptor antagonists like abciximab and the use of atherectomy/rotablator in given situations has greatly improved procedural outcome today. Angioplasty alleviates symptoms in patients with stable angina and also in unstable angina especially in high risk patients like those with pulmonary oedema, cardiogenic shock or patients refractory to conventional modes of therapy, though cost may be a prohibiting factor. The outcome of angioplasty in diabetic patients is universally poor and bypass surgery is always a better option. Women with coronary artery disease tend to have complex lesions with a sub-optimal outcome and a higher incidence of restenosis. Use of abciximab is always beneficial in both men and women.

BACKGROUND: The prevalence of risk factors for atherosclerosis is increasing in India due to changing socioeconomic factors and lifestyles. Data for the state of Andhra Pradesh are scanty in this regard. METHODS AND RESULTS: The prevalence of conventional risk factors for atherosclerosis was prospectively assessed in a unique sample of 3307 workers of a political party drawn from all over the state of Andhra Pradesh. Demographic, anthropometric, clinical and laboratory data were collected prospectively over a period of 6 months. The mean age of the subjects was 43.12+/-9.5 years, 2955 (88%) were males and 385 (12%) females. The prevalence of risk factors was as follows: diabetes in 810 (24%); hypertension in 924 (28%); lipid abnormality in 1908 (58%); smoking in 805 (24%) and positive family history in 555 (17%). Obesity was prevalent in 1178 (36%) of the population. All coronary risk factors, excepting family history, were significantly more prevalent in males [diabetes: 777 (26%) v. 34 (9%), p<0.001; hypertension: 833 (28%) v. 72 (19%), p<0.001; lipid abnormality: 1729 (59%) v. 172 (45%), p<0.001; smoking: 801 (27%) v. 7 (2%), p<0.001; and family history: 497 (17%) v. 60 (16%), p=0.54]. Region-wise analysis showed a high prevalence of diabetes in the Andhra and Rayalaseema regions, hypertension in the Andhra region, and smoking in the Rayalaseema region. Lipid disorders were equally prevalent in all the regions. CONCLUSIONS: The present report shows a disturbing burden of coronary risk factors in the study population. There is an urgent need to undertake population-based measures to reverse the trend.

BACKGROUND: An increased level of plasma homocysteine is being recognized as a new risk factor for coronary artery disease. Since there are not enough data about its importance in Indians with coronary artery disease, we aimed to assess the significance of plasma homocysteine as a coronary risk factor in South Indian patients. METHODS AND RESULTS: In a case-control study, fasting plasma homocysteine levels were estimated in 565 subjects, of whom 221 were cases and 344 were controls. Of the 221 clinically defined cases, 112 underwent coronary angiography while 107 of the 344 controls had angiographically proven normal coronary arteries. Ninety healthy volunteers from the community were also included as controls. Fluorescent polarization immunosorbent assay was used to measure plasma homocysteine levels. In 12 patients, this method was compared to high pressure liquid chromatography and was found to give comparable results. The mean plasma homocysteine level was 18.30 +/- 10.08 micromol/L in clinically defined cases and 18.04 +/- 10.69 micromol/L in controls. Similarly, in angiographicallyproven coronary arterydisease patients, the mean plasma homocysteine levelwas 18.49 +/- 10.04 micromol/L and in individuals with angiographically normal coronary arteries, it was 19.16 +/- 11.38 micromol/L. CONCLUSIONS: There is no statistically significant difference in plasma homocysteine levels between controls and cases with coronary artery disease. The mean plasma homocysteine levels in controls as assessed by fluorescent polarization immunosorbent assay in the present study population are higher as compared to other published reports.
