Analysis of polymorphisms in the dopamine beta hydroxylase gene: association with attention deficit hyperactivity disorder in Indian children

OBJECTIVE: To study the association of Attention Deficit Hyperactivity Disorder (ADHD) and polymorphism in the dopamine beta hydroxylase (DBH) gene in Indian ADHD cases. SUBJECTS: Forty one ADHD cases were diagnosed as per the DSM-IV-TR criteria and evaluated by Conners Parents and Teachers Rating Scale and Wechslers Intelligence Scale for Children. METHODS: Genomic DNA was amplified for exon 2 *444g/a and intron 5 (Taq I) polymorphism in the DBH gene followed by restriction fragment length polymorphism (RFLP) analysis. Haplotype-based haplotype relative risk (HHRR) was analyzed to ascertain the transmission pattern of these two polymorphisms in ADHD cases. Linkage disequilibrium (LD) between the two polymorphisms was calculated using EH+ and 2LD programs. RESULTS: In the limited number of samples analyzed, a slight increase in transmission of the 444a allele in ADHD subjects was observed for DBH 444g/a. The intron 5 (Taq I) polymorphism showed no significant association with ADHD in these cases. Strong disequilibrium was observed between DBH444g/a and intron 5 (Taq I) polymorphism. CONCLUSION: This is the first molecular genetic study on ADHD in Indian subjects exploring transmission of polymorphisms in the DBH gene. Preliminary investigation shows a trend towards association between the transmission of DBH444a allele and ADHD. No association was noticed between transmission of intron 5 (Taq I) polymorphism and ADHD in the Indian subjects. Presence of strong LD may point towards co-segregation of these two polymorphisms more often than expected.     

A new tool for measurement of process-based performance of multispecialty tertiary care hospitals

There is an increasing need of a model for the process-based performance measurement of multispecialty tertiary care hospitals for quality improvement. Analytic hierarchy process (AHP) is utilized in this study to evolve such a model. Each step in the model was derived by group-discussions and brainstorming sessions among experienced clinicians and managers. This tool was applied to two tertiary care teaching hospitals in Barbados and India. The model enabled identification of specific areas where neither hospital performed very well, and helped to suggest recommendations to improve those areas. AHP is recommended as a valuable tool to measure the process-based performance of multispecialty tertiary care hospitals.     

Inter-state disparities in health care and financial burden on the poor in India

Over five decades of independence, India has made rapid strides in various sectors. However, its performance in social sectors and particularly the healthcare sector has not been too rosy. Being the State's responsibility the healthcare has traditionally been influenced by individual State's budgetary allocation. Consequently inter-state disparity in availability and utilization of health services and health manpower are distinctly marked. This has implications for achievement of Health for All for the nation as a whole. Keeping in view the significance of studying inter-state variations in healthcare, this study focuses on the performance of healthcare sector in 15 major States in India. This is attempted through a comparative analysis of various parameters depicting availability of health services, their utilization and health outcomes. Our analysis depicts the prevalence of considerable inequity favoring high income group of States. In terms of healthcare resources, for instance, it indicates that the high income States hold a superior position in terms of: per capita government expenditure on medical and public health, total number of hospitals and dispensaries, per capita availability of beds in hospitals and dispensaries and health manpower in rural and urban areas. These parameters of availability have an impact on utilization levels and health outcomes in these States. A comparative profile of high and low income States as well as middle and low income States, both in rural and urban areas, reaffirms a greater financial burden in availing treatment at OPD and inpatient in low income States. In line with the higher financial burden and low per capita health expenditure, the health outcome indicators also depict a disconcerting situation in regard to low income States. These States are marked by lower life expectancy and higher incidence of diseases as well as high mortality rates. In this regard, demand as well as supply side constraints are observed which restrain the optimum utilization of existing health services. Among the low income States the main constraints on the demand side include illiteracy, malnutrition, and lack of infrastructure in accessing the facilities. Certain state specific supply side factors add significantly to under-utilization in low income States. In some of the States, however, corrective actions have been initiated to overcome the problem of the quality and low utilization of health facilities. In due course of time, it is likely that proper implementation of these measures may result in improved utilization level of existing health services, which may be useful to improve health status indicators. Nonetheless, overcoming the current levels of regional disparities in healthcare across three income groups of States may also require additional resources. The latter could be mobilized through assistance of donor agencies and appropriate mix of social and private insurance. Ultimately mitigating the problem of regional disparities in healthcare and protecting the poor and vulnerable from financial burden may require establishing and maintaining proper linkages between socio-economic development and healthcare planning.     

Purohit technique of vaginal hysterectomy: a new approach

To ease intra-operative access to laterally at vaginal hysterectomy, we have developed the 'Purohit technique of vaginal hysterectomy' using a right angle forceps, electrocautery and 10 mm telescope with light source. A prospective study on consecutive 214 women with benign disease of the uterus without prolapse, including cases with relative contraindications (excluding endometriosis and uteri above 20 weeks size), demonstrated it to be easy, safe and effective. Vaginal hysterectomy was successfully completed in 213 (99.53%) cases, with one failure (0.46%) which needed laparoscopic assistance. Vaginal salpingo-oophorectomy was completed in all indicated cases. We believe that many abdominal and laparoscopic hysterectomies could be avoided by this technique. Details of the technique can be seen on the following website http://www.purohittechnique.com     

Manual removal of the placenta and postcesarean endometritis

OBJECTIVE: To determine if manual vs. spontaneous delivery of the placenta at cesarean section affects the rate of postoperative endometritis and amount of blood loss. STUDY DESIGN: A prospective, randomized study was carried out on patients who had cesarean delivery assigned either to spontaneous delivery of the placenta (group 1) or manual removal (group 2). We excluded patients undergoing emergency cesareans and those with possible placenta accreta or evidence of preexisting infection. Outcome measures (frequency of endometritis and quantitative decrease in hemoglobin) were compared for the two groups. RESULTS: Study criteria were met for 375 subjects: 177 in group 1 and 198 in group 2. Endometritis was diagnosed in 1.7% of the former and 2.5% of the latter. The change in hemoglobin, reflecting operative blood loss, was similar in both groups (-1.81 and -1.72 g/dL, respectively). CONCLUSION: We found no significant difference in either postoperative endometritis or blood loss regardless of the means used to effect delivery of the placenta. The frequency of febrile morbidity in our study cases was considerably lower than heretofore reported.     

Inverted pneumatic retinopexy: a method of treating retinal detachments associated with inferior retinal breaks

PURPOSE: To introduce the new approach of inverted pneumatic retinopexy for the management of rhegmatogenous retinal detachments with inferior retinal breaks. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Eleven patients presenting with rhegmatogenous retinal detachments with causative inferior retinal breaks. INTERVENTION: Sterile gas/air injection, cryopexy/laser retinopexy, with inverted positioning. MAIN OUTCOME MEASURES: Postoperative primary and final anatomical outcome, visual acuity, and complications. RESULTS: Patients were followed for a minimum of 3 months (mean, 5.1 months). Primary retinal reattachment was obtained in 10 of 11(91%) patients. One patient sustained a redetachment secondary to proliferative vitreoretinopathy, resulting in a single operation reattachment rate of 82%. Final reattachment was obtained in 11 of 11 (100%) patients. Mean visual acuity improved about 3 lines from 20/60 to 20/30, with 11 of 11 patients experiencing improvement in their visual acuity. Two patients required an additional surgical procedure to achieve final anatomic success. No new breaks were identified in the postoperative period, and no complications resulted from the pneumatical procedure. CONCLUSIONS: Inverted pneumatic retinopexy can successfully repair retinal detachments with inferior retinal breaks under appropriate conditions.

Women and small cell lung cancer: social characteristics, medical history, management and survival: a retrospective study of all the male and female cases diagnosed in Bas-Rhin (Eastern France) between 1981 and 1994

The literature make it clear that lung cancer in women differs from that in men in several specific aspects. We conducted a retrospective study of the 967 consecutive recorded patients (696 men and 91 women after exclusions) diagnosed with small cell lung cancers (SCLC) between 1981 and 1994 in the Bas-Rhin population-based cancer registry to determine if such particularities could be observed in SCLC. Data included demographic and social characteristics, medical and smoking history, management (diagnosis and treatment), hospitalisation and survival. The end point for survival was 31 December 1998. Women were more frequently single, divorced, or widowed (P=0.007) and lived more often in urban areas (places with more than 10,000 inhabitants) (P=0.017). They differed significantly from men in their tobacco exposure (P=0.0001) and non-smoking rates (P=0.0003) but not in clinical presentation, except for more frequently elevated LDH levels (P=0.02). Bone marrow biopsies were more often performed in men (P=0.004), but management was otherwise comparable. The mean number of hospitalisations (for any reason) was comparable in both sexes but women tended to remain hospitalised longer (P=0.057). Overall survival did not differ, but women older than 70 years died sooner than their male counterparts (P=0.026). Our study confirms that some of gender differences reported in the lung cancer literature exist in SCLC. Sex-related differences in LDH levels have not previously been reported, to our knowledge. North American and European data concerning survival among women and men are discordant. Whether these gender differences are related to a real difference between the sexes or simply to differential exposure to carcinogens remains to be determined.
