Short-term Outcomes in Patients with Carcinoma of the Esophagus and Gastroesophageal Junction Receiving Neoadjuvant Chemotherapy or Chemoradiation before Surgery. A Prospective Study.

BACKGROUND: Neoadjuvant chemotherapy (NACT) and neoadjuvant chemoradiotherapy (NACRT) have been demonstrated to improve survival compared to surgery alone in esophageal carcinoma, but the evidence is scarce on which of these therapies is more beneficial, particularly with regard to resectability rates, postoperative morbidity and mortality, and histological responses. OBJECTIVE: This study compares the resectability, pathological response rates, and short-term surgical outcomes in patients with carcinoma of the esophagus or gastroesophageal junction receiving NACT or NACRT prior to surgery. METHODS: Patients with resectable carcinoma of the esophagus or gastroesophageal junction adenocarcinoma, squamous cell carcinoma, and adenosquamous histologies were enrolled in this well-matched prospective non-randomized study. Thirty-five patients were given NACT, and 35 NACRT. In the NACT group, 25 patients received three cycles of three-weekly carboplatin and paclitaxel, and 10 received three cycles of cisplatin/5-fluorouracil, while all the patients in the NACRT group received 41.4 Gy of radiotherapy concomitant with five cycles of weekly paclitaxel and carboplatin-based chemotherapy. RESULTS: Twenty-two patients in the NACT group and 33 patients in NACRT group had resection (P value = 0.0027). The percentage of microscopically margin-negative resection (R0 resection) was similar in both the groups (86% versus 88%). The incidences of surgical and non-surgical complications were similar in both the groups (P=0.34). There was no 30-day mortality. There was a trend toward more pathological complete regression in the NACRT group (P=0.067). The percentage of patients achieving complete tumor regression at the primary site (pT0) was significantly higher in the NACRT group. The down-staging effect on nodal status was similar in both the groups (P=0.55). There was a statistically significant reduction in tumor size in the NACRT group. The median numbers of nodes harvested and positive nodes were similar in both the groups. CONCLUSION: Patients receiving NACRT had better resectability rates and pathological response rates, but similar postoperative morbidity compared to the NACT group.

How much does a verbal autopsy based mortality surveillance system cost in rural India?

OBJECTIVE: This paper aims to determine the cost of establishing and sustaining a verbal-autopsy based mortality surveillance system in rural India. MATERIALS AND METHODS: Deaths occurring in 45 villages (population 185,629) were documented over a 4-year period from 2003-2007 by 45 non-physician healthcare workers (NPHWs) trained in data collection using a verbal autopsy tool. Causes of death were assigned by 2 physicians for the first year and by one physician for the subsequent years. Costs were calculated for training of interviewers and physicians, data collection, verbal autopsy analysis, project management and infrastructure. Costs were divided by the number of deaths and the population covered in the year. RESULTS: Verbal-autopsies were completed for 96.7% (5786) of all deaths (5895) recorded. The annual cost in year 1 was INR 1,133,491 (USD 24,943) and the total cost per death was INR 757 (USD 16.66). These costs included training of NPHWs and physician reviewers Rs 67,025 (USD 1474), data collection INR 248,400 (USD 5466), dual physician review for cause of death assignment INR 375,000 (USD 8252), and project management INR 341,724 (USD 7520). The average annual cost to run the system each year was INR 822,717 (USD18104) and the cost per death was INR 549 (USD 12) for the next 3 years. Costs were reduced by using single physician review and shortened re-training sessions. The annual cost of running a surveillance system was INR 900,410 (USD 19814). DISCUSSION: This study provides detailed empirical evidence of the costs involved in running a mortality surveillance site using verbal-autopsy.

Right internal mammary artery versus radial artery as second arterial conduit in coronary artery bypass grafting: a case-control study of 1526 patients.

OBJECTIVE: Additional arterial grafts such as the right internal mammary artery (RIMA) or the radial artery (RA) have been proposed to improve long term outcomes in coronary artery bypass grafting (CABG). RA is largely preferred over RIMA as it is less technically demanding and there is a perception that bilateral IMA usage increases the risk of sternal wound complications. However, there is a paucity of direct comparison of the two conduits to guide surgeons to choose the best second arterial conduit for CABG. METHODS: A propensity score adjusted analysis of patients undergoing multiple arterial grafting with RIMA (n = 747) and RA (n = 779) during the study period (2001-2013) was conducted to investigate the impact of the two strategies on early and late outcomes. RESULTS: RIMA did not increase the incidence of postoperative complications including deep sternal wound infection (P = 0.8). Compared to the RIMA, the RA was associated with an increased risk for late mortality (Hazard Ratio [HR] 1.9; 95% confidence interval (CI) 1.2-3.1; P = 0.008) and repeat revascularization (HR 1.5; 95% CI 1.0-2.2; P = 0.044). A trend towards an extra risk for late mortality from RA over RIMA was observed among diabetic (HR 3.3; 95% CI 1.1-9.7) and obese patients (HR 2.1; 95% CI 0.8-5.46). CONCLUSIONS: RIMA as a second conduit did not increase the operative risk including sternal wound complications and improved long term outcomes including overall survival when compared to RA. This advantage was stronger among diabetic and obese patients. These findings strongly support RIMA as the first choice second arterial conduit in CABG. Further randomized studies with angiographic control and long-term follow-up are needed to address this issue.

Success of myringoplasty: our experience.

The purpose of this study is to compare the efficacy of myringoplasty with or without cortical mastoidectomy in terms of freedom from discharge, graft take up and improvement in hearing. This is a Clinical prospective study of 120 patients from among a group of patients with chronic suppurative otitis media. A detailed history and examination was conducted including pure tone audiogram. Patients were randomly divided into two groups; group A would undergo myringoplasty only and group B would undergo cortical mastoidectomy with myringoplasty. Patients were reviewed after 3 weeks for inspection of the operated ear. Second post-operative review was at 3 months for clinicoaudiological assessment. Group B was found to have slightly more improvement as compared to the other group. No significant difference in the success rates of graft take-up in patients with unilateral or bilateral disease was found. Higher take up rates were seen in large (91.83 %) and medium perforations (90.69 %). In all our failed cases, post-operative ear discharge continued to be a persistent and troubling problem. The average audiological gain was 12.88 dB in group B, whereas it was 12.40 dB in group A. The reduction of air bone gap within each group was found to be significant. There is no statistical significant data indicating that tympanoplasty with mastoidectomy yields better results. When considering the addition of a mastoidectomy to a Tympanoplasty, the performing surgeon should consider not only the potential added benefit but also potential risks and costs to the patient.

Sudden cardiac death after acute ST elevation myocardial infarction: insight from a developing country.

BACKGROUND: There is no data concerning sudden cardiac death (SCD) following acute ST elevation myocardial infarction (STEMI) in India. We assessed the incidence and factors influencing SCD following STEMI. METHODS: Patients with STEMI admitted in our hospital from 2006 to 2009 were prospectively entered into a database. In the period 2010-2011, patients or their kin were periodically contacted and administered a questionnaire to ascertain their survival, and mode of death if applicable. RESULTS: Study population comprised of 929 patients with STEMI (mean age 55±17 years) having a mean follow-up of 41±16 months. The total number of deaths was 159, of which 78 were SCD (mean age 62.2±10 years). The cumulative incidence of total deaths and SCD at 1 month, 1, 2, 3 years and at conclusion of the study was 10.1%, 13.2%, 14.6%, 15.8%, 17.3% and 4.9%, 6.5%, 8.0%, 8.9% and 9.7%, respectively. The temporal distribution of SCD was 53.9% at first month, 19.2% at 1 month to 1 year, 15.4% in 1-2 years, 7.6% in 2-3 years and 3.8% beyond 3 years. Comparison between SCD and survivor cohorts by multivariate analysis showed five variables were found to be associated with SCD (age p=0.0163, female gender p=0.0042, severe LV dysfunction p=0.0292, absence of both reperfusion and revascularisation p=0.0373 and lack of compliance with medications p <0.0001). CONCLUSIONS: SCD following STEMI accounts for about half of the total deaths. It involves younger population and most of these occur within the first month. This data has relevance in prioritising healthcare strategies in India.

Epidemiology of sudden cardiac death in rural South India - insights from the andhra pradesh rural health initiative.

BACKGROUND: Sudden cardiac death (SCD) is a common initial presentation of coronary artery disease (CAD). Despite the growing epidemic of CAD in India, the epidemiology of SCD is largely unknown. OBJECTIVE: The objective of the study was to define the prevalence and determinants of sudden cardiac deaths in rural South India. METHODS: Prospective mortality surveillance was conducted in 45 villages (180,162 subjects) in rural South India between January 2006 and October 2007. Trained multipurpose health workers sought to do verbal autopsies within 4 weeks of any death. Detailed questionnaires including comorbidities and circumstances surrounding death were recorded. SCD was adjudicated using the modified Hinkle-Thaler classification. RESULTS: A total of 1916 deaths occurred in the study population over the 22 month time period and verbal autopsy was obtained in 1827 (95%) subjects. Overall mean age of the deceased was 62 ± 20 years and 1007 (55%) were men. Cardiovascular and cerebrovascular diseases together accounted for 559 deaths (31%), followed by infectious disease (163 deaths, 9%), cancer (126 deaths, 7%) and suicide (93 deaths, 5%). Of the 1827 deaths, after excluding accidental deaths (89 deaths), 309 deaths (17%) met criteria for SCD. Cardiovascular disease was the underlying causes in the majority of the SCD events (231/309 (75%)). On multivariate analyses, previous MI/CAD (p < 0.001, OR 14.25), hypertension (p < 0.001, OR 1.84), and age groups between 40-60 yrs (p=0.029) were significantly associated with SCD. CONCLUSION: Sudden cardiac death accounted for up to half of the cardiovascular deaths in rural Southern India. Traditional cardiovascular risk factors were strongly associated with SCD.

Rationale and design of the Rural Andhra Pradesh Cardiovascular Prevention Study (RAPCAPS): a factorial, cluster-randomized trial of 2 practical cardiovascular disease prevention strategies developed for rural Andhra Pradesh, India.

BACKGROUND: Developing countries are experiencing increasing levels of cardiovascular disease (CVD). Although there is a good understanding of how to deliver CVD prevention programs in developed countries, there are few data regarding strategies for CVD prevention in resource-poor settings. This study aimed to implement and evaluate a CVD prevention program in a rural area of India. METHODS: The 2 strategies of CVD prevention to be investigated are an algorithm-based care approach and a health-promotion campaign. A factorial, cluster-randomized trial design will be used to evaluate these, in which villages will be exposed to one, both, or neither of the interventions for a period of about 12 months. Surveys of households in every village will be used to assess outcomes in all high-risk individuals and a sample of the general adult population. RESULTS: The primary outcome of the algorithm-based component of this study will be the percentage of high-risk individuals that have been "identified"-defined as having received a cardiovascular-risk assessment in the last 12 months. The primary outcome for the health-promotion component will be the percentage of the adult population with correct knowledge about the effects of 6 behavioral determinants of cardiovascular risk (green-leafy vegetables, fruits, oily foods, salt, smoking, physical activity). Secondary outcomes include a range of measures defining uptake of different preventive strategies. CONCLUSIONS: This study will provide evidence about the effectiveness of a simple practical mechanism of CVD preventive care specifically designed for delivery in a resource-poor area in India.

Significant lipid, adiposity and metabolic abnormalities amongst 4535 Indians from a developing region of rural Andhra Pradesh.

BACKGROUND AND OBJECTIVE: Both migrant and local urban populations of Asian Indians have high rates of cardiovascular disease. Metabolic risk factors appear key to this phenomenon but data from rural India are few. We sought to determine the prevalence and distribution of lipids, obesity and metabolic syndrome in a rural region of Andhra Pradesh. METHODS: Sampling was done in 20 villages representative of the project area with an age- and sex-stratified group of 4535 adults > or =30 years selected at random from a local census list. The sample represented 13% of all adults > or =30 years in the 20 villages with a response rate of 81%. All participants had interviewer administered questionnaire, physical examination and fasting finger-prick glucose. Every fourth individual had venous blood testing for lipid profile (n=1085). Analysis was done using weighting to obtain estimates of risk factor levels for the adult population in the 20 villages. In addition to standard WHO and 2005 NCEP-ATPIII classifications, exploratory 'Asian' definitions were used for overweight and abdominal obesity. RESULTS: The population mean levels of total, LDL, HDL-cholesterol and triglycerides were 4.5 (4.4-4.6) mmol/L, 2.8 (2.7-2.9) mmol/L, 1.1 (1.06-1.13) mmol/L, 1.5 (1.4-1.6) mmol/L for men; and 4.8 (4.7-4.9) mmol/L, 3.0 (3.0-3.1) mmol/L, 1.2 (1.16-1.22) mmol/L, 1.3 (1.2-1.4) mmol/L for women. 18.4% of men and 26.3% of women were overweight rising to 32.4% of men and 41.4% of women if 'Asian' definitions were used. Criteria for NCEP-ATPIII metabolic syndrome were met by 26.9% of men and 18.4% of women with figures of 32.5% and 23.9%, respectively, if 'Asian' waist cut-offs were substituted. CONCLUSIONS: Dyslipidaemia, adiposity and metabolic syndrome were common in this rural Indian population and prevalence was much greater if proposed Asian definitions for adiposity were used. Metabolic risk factors likely play a major role in cardiovascular disease in this region.

Chronic diseases now a leading cause of death in rural India--mortality data from the Andhra Pradesh Rural Health Initiative.

INTRODUCTION: India is undergoing rapid epidemiological transition as a consequence of economic and social change. The pattern of mortality is a key indicator of the consequent health effects but up-to-date, precise, and reliable statistics are few, particularly in rural areas. METHODS: Deaths occurring in 45 villages (population 180 162) were documented during a 12-month period in 2003-04 by multipurpose primary healthcare workers trained in the use of a verbal autopsy tool. Algorithms were used to define causes of death according to a limited list derived from the international classification of disease version 10. Causes were assigned by two independent physicians with disagreements resolved by a third. RESULTS: A total of 1354 deaths were recorded with verbal autopsies completed for 98%. A specific underlying cause of death was assigned for 82% of all verbal autopsies done. The crude death rate was 7.5/1000 (95% confidence interval, 7.1-7.9). Diseases of the circulatory system were the leading causes of mortality (32%), with similar proportions of deaths attributable to ischaemic heart disease and stroke. Second was injury and external causes of mortality (13%) with one-third of these deaths attributable to deliberate self harm. Third were infectious and parasitic diseases (12%). Tuberculosis and intestinal conditions each caused one-third of deaths within this category. HIV was assigned as the cause for 2% of all deaths. The fourth and fifth leading causes of death were neoplasms (7%) and diseases of the respiratory system (5%). CONCLUSION: Non-communicable and chronic diseases are the leading causes of death in this part of rural India. The observed pattern of death is unlikely to be unique to these villages and provides new insight into the rapid progression of epidemiological transition in rural India.

Elongated styloid process (Eagle's syndrome): a clinical study.

PURPOSE: Elongated styloid process can be a source of craniofacial and cervical pain and remains a diagnostic challenge to many. The aim of the study was to determine the symptomatology and various criteria for the diagnosis of an elongated styloid process and its management. PATIENTS AND METHODS: Our clinical study consisted of 58 patients with elongated styloid process who had symptoms of vague cervicofacial pain and presented to our department during a period of 10 years. Special emphasis is given to palpation of the tonsillar fossa, lidocaine infiltration test, and orthopantomography. RESULTS: Minimal complications and zero incidence of deep neck infection were noted. CONCLUSIONS: All of the patients were managed surgically through the intraoral approach, which was found to be a safe procedure.
