Background : The role of endothelial injury and circulating adhesion molecule in the development and progression of diabetic peripheral neuropathy in the long-term has been established previously. Aims:0 To study the effects of short-term glycemic control using insulin and oral hypoglycemic agent therapy (OHA) on the peroneal nerve function and vascular cell adhesion molecule-1 (VCAM-1) and advanced glycation endproducts (AGE) levels in type 2 diabetic patients. Settings and Design : A randomized controlled study involving poorly controlled (HbA1c, 7.5%-11%) type 2 diabetic patients attending the endocrinology outpatient center in a tertiary hospital in Kuala Lumpur. Materials and Methods Twenty-nine patients were randomized to receive insulin (n=15) or OHA (n=14) for 8 weeks. The glycemic variables (HbA1c, fasting plasma glucose [FPG], fructosamine), VCAM-1, serum AGE and the peroneal motor conduction velocity (PMCV) were measured at baseline and at 4-week intervals. Statistical Analysis Used : Paired 't' test or Kruskal Wallis test; and the unpaired 't' test or Mann-Whitney U test were used for within-group and between-group analyses, respectively. Correlation was analyzed using Spearman's correlation coefficient. Results : Within-group analysis showed significant progressive improvement in HbA1c at weeks 4 and 8 in the insulin group. The PMCV improved significantly in both groups by week 8, and by week 4 (P = 0.01) in the insulin group. PMCV correlated negatively with VCAM-1 (P = 0.031) and AGE (P = 0.009) at week 8. Conclusion : Aggressive glycemic control with insulin improves the peroneal nerve function within 4 weeks. Improvement in the serum VCAM-1 and AGE levels correlated significantly with improvement in peroneal nerve conduction velocity only in the insulin group.

Background : Many doctors are dissatisfied with their jobs, which is due to long working hours and overwork. This can affect patient care and reduce quality of care. Objectives : To study job satisfaction among doctors in a tertiary hospital in Delhi and the various factors related with it. Materials and Methods: Data collection was done among 250 doctors on tenure-based job, selected by stratified random sampling, in a teaching hospital in Delhi, by using a self-administered questionnaire. Statistical Analysis : Proportions and Chi-square tests. Results : The mean number of work-hours among doctors was 9.7 ± 2.7 hours per day, and the mean number of night shifts was 5.6 per month. About half (49.6%) of the doctors were dissatisfied with the average number of work-hours per day. Dissatisfaction was significantly more in those who had an average of >8 work-hours per day and who had ≥8 night shifts per month. About half (45.6%) of the doctors considered their salary as 'bad,' and this was significantly more among unmarried doctors, interns and those who had ≥8 night shifts per month. More than half (55.2%) of the doctors were dissatisfied with their choice of profession, i.e., being a doctor, as compared to other professions. Conclusions : A significant proportion of doctors were found to be dissatisfied with the average number of their work-hours and salary. Factors like the average number of work-hours per day and the number of night shifts per month were found to have a significant relation with dissatisfaction. Further studies are needed to explore how best the work-hours of doctors could be adjusted to improve their job satisfaction.

Background : Medication is the most common health-care intervention, and the errors arising out of its usage are potentially an avoidable cause of iatrogenic injuries. There are reports of medication errors from neonatal emergency setups. Aims : To study the medication errors of ordering, dispensing and administering in neonates admitted for emergency care and to compare the errors occurring in the emergency department (ED) with those occurring in the neonatal intensive care unit (NICU) of a teaching hospital in north India. Primary objective: To study the medication errors in ordering and dispensing for neonates. Secondary objective: To compare these errors in 2 different settings - ED and NICU. Materials and Methods : We did a retrospective chart review of neonatal prescriptions written in the 4 months from January to April 2004 in the neonatal intensive care unit and the pediatric emergency department. The prescriptions were analyzed from the case records bearing an even registration number, obtained from the hospital 'medical records' section. Medication error was defined as 'any preventable event that occurs in the process of ordering, transcribing, dispensing, administering or monitoring a drug irrespective of whether the injury occurred or potential for injury was present.' Results : A total of 821 prescriptions were analyzed and 81 (9.6%) errors were detected. The error rate was found to be 1.5 (54/38) and 0.7 (27/38) per patient in ED and NICU, respectively, being highly significant in ED. Every tenth prescription had medication error in ordering or dispensing; of this, every sixth prescription in ED and nineteenth prescription in NICU had medication error. Dosing errors were the commonest form of detected errors. None of the errors caused any significant harm to the patient but had the potential to cause severe injury, and majority of these errors were preventable. Conclusion : Medication errors are common in neonatology; more so, in emergency departments than in the neonatal intensive care units.

Background : Normal breast ducts contain at least 3 types of epithelial cells: luminal (glandular) cells, basal/myoepithelial cells and stem cells. Myoepithelial and luminal epithelia can be distinguished by their different cytokeratin expression patterns. The aim of this study is to evaluate the expression of some prognostic biomarkers (ER, PR and HER2), as well as histological grading and lymph node status in cytokeratin-based groups of breast cancer. Objective: To evaluate the correlation between expression of basal and luminal markers and hormonal receptors, HER2/neu, age, grade and lymph node status in breast-invasive ductal carcinoma. Materials and Methods : Sixty-seven formalin-fixed and paraffin-embedded breast cancer specimens (of invasive ductal carcinoma, 'NOS' type) which had already been studied for ER, PR and HER2/neu were selected. Data concerning age, tumor grade and lymph node status were also obtained from archives. Expression of basal (CK5/6) and luminal (CK7) cytokeratins was detected by immunohistochemistry. Stained sections were classified according to the intensity of staining and the percentage of stained cells. Results : We categorized the cases into 3 distinct phenotype groups: pure luminal, basal phenotype and null. Pure basal, mixed basal and luminal groups were classified as expressing a basal phenotype. There was a significant difference in the ER and/or PR expression between those 3 groups and a significant association between ER and/or PR negativity and basal phenotype expression. There was no significant difference in HER2/neu expression, age of the patients, tumor grade and lymph node status between the 3 cytokeratin-based groups and no significant association between lymph node status and basal phenotype expression. Conclusion : We found that to gain a real association between basal phenotype and prognostic markers, we should use a cocktail or a panel of different biomarkers to correctly determine basal-like phenotype of breast cancers. This approach guarantees more concordance with gene expression-based studies.
