BACKGROUND AND OBJECTIVES: Mycobacterial infections are known to induce the development of autoantibodies and a few of these antibodies are also known to be diagnostic markers for some other diseases and it is uncertain whether these autoantibodies play a role in the pathogenesis of autoimmune disorders. This study was undertaken to determine the prevalence of autoantibodies like anti-neutrophil cytoplasmic antibodies (ANCA), anti-nuclear antibodies (ANA), anti-double stranded antibodies (anti-dsDNA) and anti-histone antibodies (AHA)in pulmonary Tuberculosis. MATERIALS & METHODS: Seventy consecutive pulmonary TB patients, 30 patients of interstitial lung disease and 100 normal individuals were studied. ANCA and ANA were detected by indirect immunofluorescence test (IIF). Anti-dsDNA and AHA were tested by ELISA. RESULTS: ANCA was detected in 30% cases, and of these 52.4% showed perinuclear pattern (p-ANCA), 38.1% cytoplasmic (c-ANCA) and 9.5% showed an 'atypical' pattern. ANCA specificities by ELISA revealed that, 47.6% had anti-Myeloperoxidase (anti-MPO), 28.6% had anti-Proteinase3 (anti-PR3) and 19.1% had anti-Lactoferrin (anti-LF) antibodies. ANA and AHA were present in 24.3% and 21.4% cases respectively whereas anti-ds DNA antibodies were absent. Normal controls showed 4% and 2% positivity for ANA and ANCA whereas disease control group of ILD showed 7% of ANA and ANCA posititivy. CONCLUSION: The presence of autoantibodies in TB patients could have a multifactorial etiology. Clinically relevant is the presence of anti-PR3 antibodies. This finding along with pulmonary and renal manifestations could lead to a false diagnosis of Wegener's granulomatosis or vice versa because these autoantibodies may be present in both diseases.

BACKGROUND: Short Tandem Repeat (STR) loci are widely considered to be effective for variety of applications including forensic applications, phylogenetic reconstruction and chimerism based post Haematopoietic Stem Cell Transplantation (HSCT) graft monitoring. For each application, specific sets of STR loci are used. AIMS: In the present study, we have attempted to use same set of STR loci for varied purposes based on their efficacy and informativity. SETTINGS AND DESIGN: Population and patient based study. MATERIALS AND METHODS: We have analyzed 5 STR loci - vWA, Tho1, FES, F13 and TPOX in 1000 North Indians. All five markers were also analyzed for chimerism based graft monitoring after HSCT in 42 HLA matched pair of patient-donor to predict the outcome of transplantation. STATISTICAL ANALYSIS: The analysis was done for Hardy Weinberg equilibrium (HWE), Heterozygosity, Polymorphism information content (PIC) and Power of Exclusion and Phylogenetic assessment. RESULTS AND CONCLUSIONS: High allelic variability in term of Heterozygosity (0.68-0.76), PIC (0.66-0.74) and high Power of exclusion (0.28-0.38) indicating high forensic utility. The ensuing PC plots finely resolved three basal clusters corresponding to three geo-ethnic groups of African, Orientals, and Caucasians. In post HSCT chimerism analysis, it was found that together these markers were informative in 38 pairs (98%) and were able to predict the chimerism status successfully. There is a possibility that these STR loci along with forensic and phylogenetic importance, can predict the outcome of HSCT successfully.

BACKGROUND: Cardiovascular health promotion in children has the potential to reduce the risk of atherosclerosis in both the individual child and the population at large. It thus seems eminently reasonable to initiate healthful lifestyle training in childhood to promote improved cardiovascular health in adult life. AIMS: To test the hypothesis that a year long, classroom-based education for the third and fourth graders could change their knowledge scores about healthy heart. SETTINGS AND DESIGN: A randomized, controlled trial in elementary schools of Bushehr/Iran. METHODS AND MATERIALS: A total of 14 elementary schools, categorized by socioeconomic types and male and female setting were selected and randomized into control or intervention groups. Subjects were 1128 third and fourth graders, aged 9 to 10 years (49.1% boys and 50.9% girls). Over a course of 8 weeks, health educators and sport teachers of the elementary schools presented two hours sessions per week on heart function, nutrition, and exercise for healthy heart and living tobacco free for the intervention group. The education program was based on HeartPower! Program, an American Heart Association program. STATISTICAL ANALYSIS: Mann-Whitney U test and Wilcoxon matched-pairs signed rank test and Bonferroni correction for the two pair wise comparisons were used. RESULTS: Total heart knowledge at posttest was 25% correct higher in the intervention than in the control group (p<0.001). Difference in means of total healthy heart knowledge scores between control and intervention group increased from 1.43 points in baseline to 4.02 points in posttest (p<0.001). CONCLUSION: It can be concluded that the classroom-based cardiovascular health promotion had a significant effect on the heart healthy knowledge. Therefore, schools provide an excellent setting for introducing comprehensive healthy heart education and promotion of cardiovascular health to the general population.

BACKGROUND: Pelvic pain is common in adolescent girls in day-to-day practice. Severity, Affect, Family and Environment (SAFE) is a recent interview strategy to approach these patients and their families.. AIM: 1. To find the prevalence of pelvic pain in adolescent girls. 2. To find out the feasibility and acceptability of 'SAFE' approach in evaluating chronic pelvic pain in adolescent girls. SETTINGS & DESIGN: 200 adolescent girls aged 13-23 years were selected at random from school and colleges nearby hospital campus. METHOD: A questionnaire method was adopted. Adolescent girls selected were divided into two groups, group I (with pain) and group II (without pain). STATISTICAL ANALYSIS: It was performed using chi-square and Fischer tests with significance of p value being taken at 0.05. RESULTS: Out of 200 adolescent girls selected for interview, prevalence of pelvic pain was found to be 37.0%. Dysmenorrhoea was also found to have significant relationship with pelvic pain. Depression and anxiety, school absences and loss of weight were found to have significant association with pain. Pelvic pain was found to be more in adolescent girls with large family size (> 4 members), single parent, both parents working, ongoing marital problems at home and was less reported when there was good parent - child communication about sex and when the teenager was well prepared for menarche by the parents and the association with the above mentioned factors was found to be significant. CONCLUSION: 'SAFE' approach contributes in identifying health problems in adolescent girls with chronic pelvic pain.
