Abstract
Congenital ectropion uveae (CEU) is a rare, non progressive anomaly characterised by the presence of iris pigment epithelium on the anterior surface and is frequently associated with anterior iris insertion, dysgenesis of the drainage angle and glaucoma. This paper describes an unusual case of bilateral congenital ectropion uveae with iris coloboma and telecanthus. The anterior chamber angle was normal and there was no evidence of glaucoma. To the best of our knowledge, this association has not been reported previously.

Abstract
OBJECTIVE Influence of socioeconomic status on cardiovascular risk has not been well studied in low income countries. To determine risks in various educational status (ES) subjects we performed a study in India. METHODS Epidemiological study was performed in years 1999-2003 in Jaipur (India) for coronary risk factors among 1280 adults 20-59 years (men 619, women 661). ES was categorized into low (education ≤5 years); middle (6-12 years) and high (>12 years). Prevalence of risk factors and Framingham risk scores were determined. RESULTS Low ES was in 306, middle in 436 and high in 538. In low, middle and high ES respectively age-adjusted prevalence (%) of smoking was 19.0, 19.3, and 11.7; obesity 9.5, 16.7, and 22.1, hypertension 15.3, 30.5, and 44.0; hypercholesterolemia ≥200mg/dl 46.0, 48.4, and 54.6; low HDL cholesterol <40mg/dl 46.4, 56.4, and 38.3; metabolic syndrome 20.9, 25.7, and 28.6; and diabetes 6.9, 5.5, and 26.4. Framingham risk score was 5.7±4.8, 6.3±5.7 and 4.7±5.1 and calculated cardiovascular risk probability 5.2±5.7, 6.8±7.8 and 5.2±6.0 (P(trend)<0.05). Framingham risk score was significantly greater in low and middle ES (6.1±5.3) compared to high (4.7±5.1) (p<0.001). Adjustment for smoking attenuated the risk. CONCLUSION Low and middle educational status urban subjects in India have greater cardiovascular risk.

Abstract
Experimental methods of infrared, Raman and electronic absorption spectroscopy and DFT calculations using B3LYP functionals and 6-31G** and 6-311++G** basis sets have been used to understand the structural and spectral characteristics of 2-pyranones, 6-phenyl-4-methylsulfanyl-2-oxo-2H-pyran and 6-phenyl-4-methylsulfanyl-2-oxo-2H-pyran-3-carbonitrile in the electronic ground (S(0)) and first excited (S(1)) states. Information about the size, shape, charge density distribution and site of chemical reactivity of the molecules has been obtained by mapping electron density isosurface with electrostatic potential surfaces (ESP). Based on TD-DFT calculations using 6-31+G**5D basis set, an assignment of absorption peaks in the UV-VIS region has been suggested. The S(1) state is found to be a (1)(pi,pi*) state. A complete vibrational analysis has been attempted on the basis of experimental infrared and Raman spectra and calculated frequency and intensity of the vibrational bands and potential energy distribution over the internal coordinates. Characteristic vibrational bands of the 2-pyranone ring and methylsulfanyl and carbonyl groups have been identified.

Abstract
BACKGROUND Otorhinolaryngological (ENT) diseases are major health problem in India but the trends in occurrence of various disorders in clinical practice have not been well studied. To assess the types of such diseases and to determine changing trends in their incidence we performed this study. METHODS The study was done at a non-government ENT center at Jaipur. From 1975 to 2005, >125000 patients of different diseases were evaluated here. The study includes randomly selected patients (n = 11454) from years 1980 to 2000 at an interval of 5 years to evaluate disease trends. Significance of trends was evaluated using least squares regression. RESULTS In the years 1980, 1985, 1990, 1995 and 2000 mean age of patients was 26.60 ± 17.81 (range 0.16 to 85), 27.07 ± 16.91 (0.08 to 90), 28.30 ± 17.73 (0.25 to 90), 28.79 ± 17.8 (0.25 to 90) and 28.74 ± 17.81 (0.25 to 85) years respectively. 51 types of ENT diseases were observed of which 19 contributed to 76.8% (8807) patients and analysis was restricted to them. Chronic suppurative otitis media (2203, 19.2%), otitis externa (859, 7.5%), deviated nasal septum with nasal obstruction (717, 6.3%) and chronic tonsillitis (695, 6.1%) were the most common, followed by ear wax (569, 4.9%), sensorineural hearing loss (545, 4.7%), chronic rhinosinusitis (428, 3.7%) and epistaxis (320, 2.8%). There was increasing trend for stomatitis (b = 0.0014), deviated nasal septum (b = 0.0290), allergic rhinitis (b = 0.0023), epistaxis (b = 0.0002), acute tonsillitis (b = 0.0003), hoarseness (b = 0.0017), deaf mutism (b = 0.0005), sensorineural hearing loss (b = 0.0038), tinnitus (b = 0.0006) and ear wax (b = 0.0050). Declining trend was observed for chronic rhinosinusitis (b = -0.0155), otitis externa (b = -0.0063), chronic suppurative otitis media (b = -0.0001), acute otitis media ( = -0.0007), secretory otitis media (b = -0.0013), otosclerosis (b = -0.0007), vertigo (b = -0.0007), neck swelling (b = -0.0005) and chronic tonsillitis (b = -0.0194). CONCLUSION This study from an Indian urban ENT center shows a significantly increasing trend in chronic and degenerative ear diseases and decline in infection related diseases.

Abstract
A systematic study has been conducted on the conformation, electronic structure and vibrational spectra of benzo[c]phenanthrene and some of its partially reduced derivatives by experimental infrared spectroscopic and quantum chemical techniques. Electrostatic potential surfaces have been mapped over the electron density isosurfaces to obtain information about the size, shape, charge density distribution and chemical reactivity of the molecules. Possibility of hydrogen-hydrogen bonding has been explored in all the molecules. Partial reduction of the aromatic rings in benzo[c]phenanthrene leads to considerable molecular distortion with the approximate mean angle between the terminal rings increasing from 27.3 degrees to 46.0 degrees . The distortion is unequally distributed near the aromatic and saturated rings; the latter absorbs most of strain due to flexibility of the rings. A complete vibrational analysis of the experimental infrared spectra has been reported on the basis of frequency and intensity of the vibrational bands and potential energy distribution over the internal coordinates and characteristic bands have been identified.

Abstract
OBJECTIVE The impact of rising population-wide obesity on cardiovascular risk factors has not been well studied in low-income countries. To correlate the prevalence of obesity with risk factors we performed epidemiological studies in India. METHODS Multiple cross-sectional epidemiological studies, Jaipur Heart Watch (JHW), were performed in India in rural and urban locations. From these cohorts, subjects aged 20-59 years (men 4102, women 2872) were included. Prevalence of various risk factors: smoking/tobacco use, overweight/obesity (body mass index > or = 25 kg/m2) truncal obesity (waist:hip > or = 0.95 men, > or = 0.85 women), hypertension, dyslipidemias, metabolic syndrome and diabetes was determined. Trends were examined using least squares regression. RESULTS Smoking/tobacco use was more in rural men (50.0% vs 40.6%) and urban women (8.9% vs 4.5%, p < 0.01). Obesity, truncal obesity, hypertension, hypercholesterolemia, diabetes, and metabolic syndrome were more in urban cohorts (p < 0.001). Age-adjusted prevalence (%) of obesity in various cohorts, rural JHW, and urban JHW-1, JHW-2, JHW-3, and JHW-4 respectively, in men was 9.4, 21.1, 35.6, 54.0, and 50.9 (r2 = 0.92, p = 0.009) and in women 8.9, 15.7, 45.1, 61.5, and 57.7 (r2 = 0.88, p = 0.018). Prevalence of truncal obesity in men was 3.2, 19.6, 39.6, 41.4, and 31.1 (r2 = 0.60, p = 0.124) and in women 10.1, 49.5, 42.1, 51.7, and 50.5 (r2 = 0.56, p = 0.1467). In successive cohorts increasing trends were observed in the prevalence of hypertension (r2 = 0.93, p = 0.008) and metabolic syndrome (r2 = 0.99, p = 0.005) with weaker trends for hypercholesterolemia (r2 = 0.41, p = 0.241) and diabetes (r2 = 0.79, p = 0.299) in men. In women, significant trends were observed for hypertension (r2 = 0.98, p = 0.001) and weaker trends for others. Increase in generalized obesity correlated significantly with hypertension (two-line regression r2, men 0.91, women 0.88), hypercholesterolemia (0.53, 0.44), metabolic syndrome (0.87, 0.94) and diabetes (0.84, 0.93). Truncal obesity correlated less strongly with the risk factors like hypertension (0.50, 0.57), hypercholesterolemia (0.88, 0.61), metabolic syndrome (0.76, 0.33), and diabetes (0.75, 0.33). CONCLUSIONS In Asian Indian subjects, escalating population-wide generalized obesity correlates strongly with increasing cardiovascular risk factors.

Abstract
OBJECTIVE To test the hypothesis that blood glucose levels in the range of normoglycemia are associated with increased cardiovascular risk we performed an epidemiological study in an urban population. METHODS Randomly selected adults > or = 20 years were studied using stratified sampling. Target sample was 1800 (men 960, women 840) of which 1123 subjects participated. Blood samples were available in 1091 subjects (60.6%, men 532, women 559). Measurement of anthropometric variables, blood pressure, fasting blood glucose and lipids was performed. Cardiovascular risk factors were determined using US Adult Treatment Panel-3 guidelines. Pearson's correlation coefficients (r) of fasting glucose with various risk factors were determined. Fasting glucose levels were classified into various groups as < 75 mg/dl, 75-89 mg/dl, 90-109 mg/dl, 110-125 mg/dl and > 126 mg/dl or known diabetes. Prevalence of cardiovascular risk factors was determined in each group. RESULTS There was a significant positive correlation of fasting glucose in men and women with body mass index (r = 0.20, 0.12), waist-hip ratio (0.17, 0.09), systolic blood pressure (0.07, 0.22), total cholesterol (0.21, 0.15) and triglycerides (0.21, 0.25). Prevalence (%) of cardiovascular risk factors in men and women was smoking/tobacco use in 37.6 and 11.6, hypertension in 37.0 and 37.6, overweight and obesity in 37.8 and 50.3, truncal obesity in 57.3 and 68.0, high cholesterol > or = 200 mg/dl in 37.4 and 45.8, high triglycerides > or = 150 mg/dl in 32.3 and 28.6 and metabolic syndrome in 22.9 and 31.6 percent. In various groups of fasting glucose there was an increasing trend in prevalence of overweight/obesity, hypertension, hypercholesterolaemia, hypertriglyceridaemia, and metabolic syndrome (Mantel-Haenzel X2 for trend, p < 0.05) and fasting glucose < 75 mg/dl was associated with the lowest prevalence of these risk factors. CONCLUSIONS There is a continuous relationship of fasting glucose levels with many cardiovascular risk factors and level < 75 mg/dl is associated with the lowest prevalence.

Abstract
Structural and spectral characteristics of ethyl 2-cyano-3-N,N-dimethyl amino acrylate have been studied by methods of X-ray crystallography, infrared spectroscopy and quantum chemistry. The compound crystallizes in monoclinic space group P2(1)/n with unit cell parameters a=4.26(1)A, b=11.16(1)A, c=19.63(3)A and beta=95.5(1) degrees . The X-ray based three-dimensional structure analysis has been carried out by direct methods and fully refined. Density functional theory calculations for potential energy curves, optimized geometries and vibrational spectra have been carried out using 6-31 G and 6-31 G basis sets and B3LYP functionals. These suggest the possibility of existence of two structural isomers for the molecule-a more stable s-cis and a less stable s-trans isomer, having enthalpy difference of 2.85 kcal/mol. The optimized molecular geometry is in agreement with experimental geometry from X-ray analysis and suggests a preferential s-cis conformation for the molecule in the solid state. Based on experimental and theoretical studies, it may be concluded that the molecule has an almost planar conformation with the cyanide group also lying in the molecular plane; the deviation from planarity does not exceed 3 degrees . The structure is stabilized by the presence of intra-molecular and inter-molecular interactions.

Abstract
BACKGROUND AND OBJECTIVE Influence of obesity as determinant of cardiovascular risk factors has not been well studied. To determine association of obesity, measured by body-mass index (BMI), waist-size or waist-hip ratio (WHR), with multiple risk factors in an urban Indian population we performed an epidemiological study. METHODS Randomly selected adults > or = 20 years were studied using stratified sampling. Target sample was 1800 (men 960, women 840). 1123 subjects (response 62.4%) were evaluated and blood samples were available in 532 men and 559 women (n=1091, response 60.6%). Measurement of anthropometric variables, blood pressure, fasting blood glucose and lipids was performed. Atherosclerosis risk factors were determined using current guidelines. Pearson's correlation coefficients (r) of BMI, waist and WHR with various risk factors were determined. BMI was categorized into five groups: <20.0 Kg/m2, 20.0-22.9, 23.0-24.9, 25.0-29.9, and > or = 30 Kg/m2; waist size was divided into five groups and WHR into six groups in both men and women. Prevalence of cardiovascular risk factors, smoking, hypertension, diabetes, metabolic syndrome and dyslipidaemias was determined in each group and trends analyzed using least-squares regression. RESULTS There is a significant positive correlation of BMI, waist-size and WHR with systolic BP (r= 0.46 to 0.13), diastolic BP (0.42 to 0.16), fasting glucose (0.15 to 0.26), and LDL cholesterol (0.16 to 0.03) and negative correlation with physical activity and HDL cholesterol (-0.22 to -0.08) in both men and women (p<0.01). With increasing BMI, waist-size and WHR, prevalence of hypertension, diabetes, and metabolic syndrome increased significantly (p for trend <0.05). WHR increase also correlated significantly with prevalence of high total and LDL cholesterol and triglycerides (p <0.05). CONCLUSIONS There is a continuous positive relationship of all markers of obesity (body-mass index, waist size and waist hip ratio) with major coronary risk factors- hypertension, diabetes and metabolic syndrome while WHR also correlates with lipid abnormalities.

Abstract
The paper reports main results of a comprehensive study of the vibrational spectrum of ketene computed using second-order perturbation theory treatment based on quartic, cubic and semidiagonal quartic force constants. Two different models--a homogeneous model using the same density functionals and basis functions for the harmonic calculations and anharmonic corrections, and a hybrid model in which the two parts of the calculation are conducted using different density functionals and basis sets--have been employed in the present calculations. Different DFT and CCSD methods and DZ and TZ extended basis sets involving diffuse and polarization functions have been used to calculate optimized and vibrationally averaged geometrical parameters, the harmonic and anharmonic vibrational frequencies and the spectroscopic constants such as anharmonicity constants, rotational constants, rotation-vibration coupling constants, Nielsen's centrifugal distortion constants and Coriolis coupling constants. Homogeneous model is found to be superior to the hybrid model in several respects. Difficulties in the hybrid model may arise due to one of the following reasons: (a) the basic requirement that the geometry optimization and frequency calculations must be done at the same level of theory to have valid frequencies is not met in the hybrid model; (b) the molecular structure gets reoptimized at the low level for anharmonic corrections; (c) in addition, the perturbation could also diverge for the above reasons, particularly for the very low, very anharmonic terms where the harmonic approximation is not close enough to make the perturbation work.

Abstract
BACKGROUND To determine prevalence of multiple coronary risk factors in a North Indian Punjabi community and to compare these with previous population based studies in the same city in North India we performed an epidemiological study. METHODS A community-based epidemiological study that focused on lifestyle determinants of obesity and its correlates in migrants from Punjab was performed at a single location in Jaipur. A house-to-house enumeration was performed to enroll all adults>or=20 years age in the locality who were then invited for participation in the study. Of the 1400 eligible subjects, 1127 participated (response rate 80.5%, men 556, women 571). Risk factor measurements included smoking or tobacco use, body-mass index (BMI), waist:hip ratio (WHR) and body fat, and in 644 (56.6%) subjects (men 340, women 304) blood examination for fasting blood glucose and lipids. Coronary risk factors were determined using pre-specified criteria. RESULTS There was a significant prevalence of risk factors in both men and women respectively with smoking or tobacco use in 209 (37.6%) and 12 (2.2%), obesity (BMI>or=25 kg/m2) in 303 (54.5%) and 350 (61.3%), truncal obesity (high WHR) in 339 (61.0%) and 310 (54.30%), hypertension in 322 (57.9%) and 279 (48.9%), high total cholesterol>or=200 mg/dl in 111 (32.6%) and 120 (39.5%), low HDL cholesterol<40 mg/dl in 103 (30.3%) and 83 (27.3%), high triglycerides>or=150 mg/dl in 146 (42.9%) and 132 (43.4%), metabolic syndrome in 166 (48.8%) and 137 (45.1%), and diabetes in 88 (25.9%) and 64 (21.1%) subjects. In both men and women there was a significant age-associated escalation in obesity, central obesity, hypertension, high cholesterol and diabetes prevalence (Mantel-Haenszel chi2 for trend p<0.05). Logistic regression analyses revealed that obesity and truncal obesity were major determinants of multiple risk factors such as hypertension, hypercholesterolemia, metabolic syndrome and diabetes (age-adjusted odds ratios p<0.01). Comparison with previous population-based risk factor studies from the same city in years 1995 and 2002 revealed that risk factors were significantly greater in the present group. Age-stratified differences revealed that obesity at younger age was more frequent in the present cohort. CONCLUSIONS There is a significant prevalence of multiple cardiovascular risk factors in this population group. Obesity is a major determinant of multiple risk factors and appears at a younger age compared to other studies in the same location.

Abstract
PURPOSE To determine the effect of entropion surgery on corneal health in terms of surface epithelium, tear film stability, change in curvature and vision. METHODS Prospective study; included consecutive patients with trachomatous upper lid entropion undergoing corrective surgery. Corneal opacity and other conditions that reduced vision were recorded. Best-corrected visual acuity, corneal fluorescein staining, tear film break-up time, Schirmer I test, and keratometry were performed before and after surgery. Data were analysed using Student's t-test, chi(2) test, one-way ANOVA, one-sample t-test, and logistic and multiple regression. RESULTS Thirty-six female and 15 male patients with an average age of 59.1+/-10.65 years were included. Lenticular and retinal causes resulted in blindness (P=0.008), and low vision (P=0.02), more often than entropion. At 90 days after surgery, vision improved by 0.55+/-1.48 lines (P=0.01). Superficial punctate staining of the cornea reduced by half over 1-15 days (average 6.96+/-4.99) after surgery, and completely in 1-90 days (average 26.15+/-17.49). Tear film break-up time (range: 3-20 s preoperatively) improved significantly after surgery (P=0.005) whereas Schirmer I (range: 10-35 mm preoperatively) and keratometry values showed insignificant change. CONCLUSIONS Surgery for entropion results in healing of superficial keratopathy, improves tear film stability, and the realigned lid margin spreads tears evenly and efficiently, thus contributing to improved vision. These changes, taking place over 1-90 days, should be kept in mind when planning intraocular surgery, keratoplasty, or keratorefractive procedures after entropion correction.

Abstract
OBJECTIVE To test the validity of internationally accepted waist circumference (WC) action levels for adult Asian Indians. DESIGN Analysis of data from multisite cross-sectional epidemiological studies in north India. SUBJECTS In all, 2050 adult subjects >18 years of age (883 male and 1167 female subjects). MEASUREMENTS Body mass index (BMI), WC, waist-to-hip circumference ratio, blood pressure, and fasting samples for blood glucose, total cholesterol, serum triglycerides, and high-density lipoprotein cholesterol. RESULTS In male subjects, a WC cutoff point of 78 cm (sensitivity 74.3%, specificity 68.0%), and in female subjects, a cutoff point of 72 cm (sensitivity 68.7%, specificity 71.8%) were appropriate in identifying those with at least one cardiovascular risk factor and for identifying those with a BMI >21 kg/m(2). WC levels of > or =90 and > or =80 cm for men and women, respectively, identified high odds ratio for cardiovascular risk factor(s) and BMI level of > or =25 kg/m(2). The current internationally accepted WC cutoff points (102 cm in men and 88 cm in women) showed lower sensitivity and lower correct classification as compared to the WC cutoff points generated in the present study. CONCLUSION We propose the following WC action levels for adult Asian Indians: action level 1: men, > or =78 cm, women, >/=72 cm; and action level 2: men, > or =90 cm, women, > or =80 cm.

Abstract
OBJECTIVE To determine trends in blood pressure (BP) and assess the statistical phenomenon of regression to the mean we performed sequential examinations in an industrial population. METHODS All the employees in an industrial plant were examined. Height, weight, body mass index (BMI) and blood pressure were measured using standardised techniques successively for 5 years as part of annual medical check-up of these employees. All the male employees (n=145) were targeted in the first year of which 122 (84.1%) were examined. These numbers declined to 121, 99, 90 and 87 in subsequent years respectively due to employee attrition. Trends in levels of systolic and diastolic BP and hypertension prevalence were examined using standard regression analysis, least-squares regression and graphic analyses using a commercially available statistical programme. RESULTS The mean age 31.3 +/- 5.9 years (range 23-41). The mean height was 1.68 + 0.06 m, weight 60.0 + 9.1 kg and BMI 21.2 +/- 3.1 kg/m2. 18 subjects (14.8%) were overweight. From the first to the fifth year, respectively, BMI increased from 21.2 +/- 3.1 kg/m2 to 21.3 +/- 3.9, 21.9 +/- 3.0, 22.3 +/- 3.0 and 22.6 +/- 2.9 kg/m2 (r = 0.93, p = 0.011), systolic BP declined from 127.1 +/- 13.5 to 125.7 +/- 15.4, 125.5 +/- 12.9, 125.0 +/- 12.6 and 124.9 +/- 14.0 mm Hg (r = -0.60, p = 0.034) while diastolic BP remained unchanged (r = 0.15). Prevalence of hypertension (> or =140 / > or =90) declined from 34.4% at baseline to 28.9, 28.3, 24.4 and 24.1% respectively (r = -0.948, p = 0.021). CONCLUSIONS A high prevalence of hypertension in observed in this young industrial cohort. Without treatment, the hypertension prevalence as well as mean systolic BP decline over time demonstrating the statistical phenomenon of regression to the mean.

Abstract
OBJECTIVE There is a wide disparity in prevalence and cardiovascular disease mortality in different Indian states. To determine significance of various nutritional factors and other lifestyle variables in explaining this difference in cardiovascular disease mortality we performed an analysis. METHODS AND RESULTS Mortality data were obtained from the Registrar General of India. In 1998 the annual death rate for India was 840/100,000 population. Cardiovascular diseases contribute to 27% of these deaths and its crude mortality rate was 227/100,000. Major differences in cardiovascular disease mortality rates in different Indian states were reported varying from 75-100 in sub-Himalayan states of Nagaland, Meghalaya, Himachal Pradesh and Sikkim to a high of 360-430 in Andhra Pradesh, Tamil Nadu, Punjab and Goa. Lifestyle data were obtained from national surveys conducted by the government of India. The second National Family Health Survey (26 states, 92,447 households, 301,984 adults) conducted in 1998-1999 reported on various demographic and lifestyle variables and India Nutrition Profile Study reported dietary intake of 177,841 adults (18 states, 75,229 men, 102,612 women). Cardiovascular disease mortality rates were correlated with smoking, literacy levels, prevalence of stunted growth at 3-years (as marker of fetal undernutrition), adult mean body mass index, prevalence of overweight and obesity, dietary consumption of calories, cereals and pulses, green leafy vegetables, roots, tubers and other vegetables, milk and milk products, fats and oils, and sugar and jaggery. As a major confounder in different states is poverty, all the partial correlation coefficients were adjusted for illiteracy, fertility rate and infant mortality rate. There was a significant positive correlation of cardiovascular disease mortality with prevalence of obesity (R=0.37) and dietary consumption of fats (R=0.67), milk and its products (R=0.27) and sugars (R=0.51) and negative correlation with green leafy vegetable intake (R=-0.42) (p<0.05). CONCLUSIONS There are large disparities in cardiovascular disease mortality in different Indian states. This can be epidemiologically explained by difference in dietary consumption of fats, milk, sugar and green-leafy vegetables and prevalence of obesity.

Abstract
BACKGROUND Studies among emigrant Indian populations have shown a high prevalence of obesity and many coronary risk factors in Bhatia community. To determine the prevalence of risk factors in this community within India we performed an epidemiological study. METHODS AND RESULTS An ethnic-group sample survey to determine prevalence of cardiovascular risk factors was performed using community registers for enrollment. Methodology used was similar to Jaipur Heart Watch studies performed in 1995 and 2002. We invited 600 randomly selected subjects listed in Punjabi Bhatia community registers and could examine 458 (76.7%) persons (men 226, women 232). Evaluation for coronary risk factors, anthropometric measurements, blood pressure, electrocardiogram, fasting blood glucose and serum lipids was performed using standard definitions. Mean age was 43.2 +/- 14.6 years in men and 44.7 +/- 15.3 years in women. In both men and women there was a high prevalence of family history of coronary heart disease in 45 (19.9%) and 50 (21.6%), family history of diabetes in 96 (42.5%) and 77 (33.2%), sedentary habits in 82 (36.3%) and 73 (31.5%), smoking or tobacco use in 59 (26.1%) and 4 (1.7%), overweight or obesity (body mass index > or = 25 kg/m2) in 123 (54.0%) and 161 (69.4%), severe obesity (body mass index >30 kg/m2) in 47 (20.8%) and 75 (32.3%), truncal obesity (waist-hip ratio: men >0.9, women >0.8) in 175 (77.4%) and 186 (80.2%), increased waist (waist size: men >102 cm, women >88 cm) in 78 (34.5%) and 129 (55.6%), hypertension (blood pressure > or = 140/90 mmHg) in 116 (51.3%) and 120 (51.3%), diabetes in 40 (17.7%) and 33 (14.2%), hypercholesterolemia (total cholesterol > or = 200 mg/dl) in 75 (33.2%) and 67 (28.9%), high triglycerides in 55 (24.3%) and 34 (14.7%), low high-density lipoprotein cholesterol in 169 (74.8%) and 155 (66.8%), and the metabolic syndrome (defined by American National Cholesterol Education Program) in 84 (36.2%) and 111 (47.8%) respectively. Body mass index correlated significantly with (age-adjusted r2 value--men, women) waist diameter (0.52, 0.12), waist-hip ratio (0.21, 0.10), truncal obesity (0.54, 0.60), systolic blood pressure (0.19, 0.16), diastolic blood pressure (0.12, 0.16), hypertension (0.19, 0.31), and metabolic syndrome (0.28, 0.44) (p<0.05). There was a significant linear relationship of body mass index with the prevalence of hypertension, hypercholesterolemia, diabetes (women), and the metabolic syndrome (chi2 for trend p<0.05). Prevalence of these risk factors was the lowest in subjects with body mass index <20 kg/m2. A multivariate ordinal logistic regression analysis revealed that obesity was independently associated with multiple risk factors characterized by metabolic syndrome after adjustment for age, hypertension, and diabetes in both men (odds ratio 2.45, 95% confidence intervals 1.69, 3.57) as well as in women (odds ratio 2.93, 95% confidence intervals 1.86, 4.61) (p<0.01). CONCLUSIONS There is a high prevalence of obesity, abdominal obesity, hypertension, diabetes, lipid abnormalities and the metabolic syndrome in this community that is significantly greater than reported studies in Jaipur and urban populations elsewhere in India. Obesity correlates strongly with multiple coronary risk factors of which it is an important determinant.

Abstract
In order to understand conformational isomerism in methacryloyl bromide (MABR) in the ground (S(0)) and the first excited (S(1)) electronic states and to interpret the vibrational and electronic spectra of its conformers in the S(0) state, quantum mechanical calculations using Density Functional Theory (DFT) and RHF methods with extended basis sets 6-31G, 6-31G** and 6-311+G(d,p) have been conducted. In RHF calculations, electron correlation effects have been included at the Møller-Plesset MP2 level. It is inferred that in both the electronic states the molecule may exist in two isomeric forms-s-trans and s-cis; the former being more stable than the later by about 1.629 kcal mol(-1) in the S(0) state and by about 2.218 kcal mol(-1) in the S(1) state. Electronic transition tends to increase the s-trans/s-cis and s-cis/s-trans, rotational barriers from 7.059 kcal mol(-1) (2468.1 cm(-1)) and 5.428 kcal mol(-1) (1897.8 cm(-1)) in S(0) state to 23.594 kcal mol(-1) (8249.4 cm(-1)) and 21.376 kcal mol(-1) (7473.9 cm(-1)) in the S(1) state. Completely optimized geometries of the two conformers in S(0) state reveal that while there is no significant difference in their bond lengths, some of the bond angles associated with COBr group are appreciably different. Electronic excitation tends to change both the bond lengths and bond angles. Based on suitably scaled DFT and RHF results obtained from the use of 6-31G** and 6-311+G(d,p) basis sets, a complete assignment is provided to the fundamental vibrational bands of both the s-trans and s-cis conformers in terms of frequency, form and intensity of vibrations and potential distribution across the symmetry coordinates in the S(0) state and a comparison has been made with experimental assignments. A theoretical prediction of the electronic transitions in the near UV-region in the two conformers and their tentative assignment has been provided on the basis of CI level calculations using 6-31G basis set.

Abstract
The objective of the study was to determine trends in age-specific blood pressure (BP) distribution and hypertension prevalence in an urban Indian population. In successive hypertension epidemiological studies (1995 and 2002), randomly selected 2212 subjects (1412 men, 797 women) in the first and 1123 subjects (550 men, 573 women) in the second study were evaluated. BP was measured using World Health Organization guidelines and hypertension diagnosed using the American Joint National Committee-VI report. Age-specific BP levels in the first and the second study were determined and compared. The mean values of systolic and diastolic BP were not significantly different in various age groups in the first and the second studies. There was an increased variance in the second study as denoted by the significant increase in standard deviations and coefficients of variation in systolic as well as diastolic BP levels at age groups > or =50 years in men and > or =40 years in women (P<0.05). The age-adjusted prevalence of hypertension (known or BP > or =140/> or =90 mmHg) in the first study was 29.5% (men) and 33.5% (women), and in the second study was 30.0% (men) and 30.3% (women) (P=NS). In the second as compared to the first study, there was decrease in age-adjusted prevalence of stage I hypertension (men 16.8 vs 24.9%, women 15.4 vs 27.5%), and increase in stage II hypertension (men 11.7 vs 2.8%, women 18.8 vs 3.1%), and combined stage II and III hypertension (men 13.5 vs 4.7%, women 16.7 vs 6.0%) (P<0.01). This change was associated with greater prevalence of obesity in the second study. In conclusion, increased systolic and diastolic BP dispersion over a 7-year period in this urban population is associated with unchanged hypertension prevalence, decline in stage I hypertension and upsurge in more severe grades. Increasing environmental factors, particularly obesity, appear important.

Abstract
OBJECTIVE Epidemiological study among urban subjects in western India to determine prevalence of diabetes, insulin resistance syndrome (IRS) and their risk factors. METHODS Randomly selected adults > or =20 years were studied using stratified sampling. Target sample was 1,800 (men 960, women 840). 1123 subjects (response 62.4%) were evaluated and blood samples were available in 532 men and 559 women (n=1091, 60.6%). Measurement of anthropometric variables, blood pressure, fasting blood glucose and lipids was performed. Atherosclerosis risk factors were determined using current guidelines. Diabetes was diagnosed when the subject was a known diabetic or fasting blood glucose was > or =126 mg/dl, impaired fasting glucose (IFG) diagnosed when fasting glucose was 110-125 mg/dl. IRS was diagnosed when any three of-IFG, high triglycerides >150 mg/dl, low HDL cholesterol (men<40 mg/dl, women<50 mg/dl), central obesity (men>102 cm, women>88 cm), or high normal blood pressure (>130/>85 mmHg) or hypertension-were present. RESULTS Diabetes was present in 70 men (13.2%) and 64 women (11.5%). Age-adjusted prevalence of diabetes was 9.3% in men (95% confidence intervals (CI) 6.7-11.8), 8.1% in women (CI 5.8-10.4) and 8.6% overall (CI 6.9-10.3). IFG was in 28 men (5.3%) and 29 women (5.2%). IRS was present in 52 men (9.8%) and 114 women (20.4%) with age-adjusted prevalence of 7.9% in men (CI 6.7-9.1) and 17.5% in women (CI 14.4-20.6) with an overall prevalence of 12.8% (CI 10.8-14.8). Other metabolic abnormalities of IRS in men and women were high triglycerides in 32.1 and 28.6%, low HDL cholesterol in 54.9 and 90.2%; central obesity in 21.8 and 44.0%, and high normal blood pressure or hypertension in 35.5 and 32.4%. IFG subjects had similar atherosclerosis risk factor profile as normal subjects while those with IRS and diabetes had significantly greater prevalence of obesity, central obesity, hypertension, high triglycerides and low HDL (P<0.01). CONCLUSIONS There is s significant prevalence of diabetes and IRS in this urban Indian population. Subjects with diabetes as well as IRS have greater prevalence of obesity, central obesity, hypertension, hypertriglyceridemia and low HDL as compared with normal subjects.

Abstract
OBJECTIVE To determine trends of coronary risk factors in an Indian urban population and their association with educational level as marker of socioeconomic status. METHODS Two successive coronary risk factor surveys were performed in randomly selected individuals. In the first study (in 1995) 2212 subjects (1415 men, 797 women) and in the second (in 2002) 1123 subjects (550 men, 573 women) were studied. Details of smoking, physical activity, hypertension, diabetes, coronary heart disease, body-mass index, waist-hip ratio, blood pressure and electrocardiography were evaluated. Fasting blood was examined for lipid levels in 297 (199 men, 98 women) in the first and in 1082 (532 men, 550 women) in the second study. Educational status was classified into Group 0: no formal education, Group I: 1-10 years, Group II: 11-15 years, and Group III: > 16 years. Current definitions were used for risk factors in both the studies. RESULTS Prevalence of coronary risk factors, adjusted for age and educational status, in the first and second study in men was smoking/tobacco in 38.7 vs. 40.5%, leisure time physical inactivity in 70.8 vs. 66.1%, hypertension (> or = 140 and/or 90 mm Hg) in 29.5 vs. 33.7%, diabetes history in 1.1 vs. 7.8%, obesity (body-mass index > or = 25 Kg/m2) in 20.7 vs. 33.0%, and truncal obesity (waist:hip > 0.9) in 54.7 vs. 54.4%. In women, tobacco use was in 18.7 vs. 20.5%, leisure time physical inactivity in 72.4 vs. 75.3%, hypertension in 36.9 vs. 33.7%, diabetes history in 1.0 vs. 7.3%, obesity in 19.9 vs. 39.4%, and truncal obesity (waist:hip > 0.8) in 70.1 vs. 69.2%. In men, high total cholesterol > or = 200 mg/dl was in 24.6 vs. 37.4%, high LDL cholesterol > or = 130 mg/dl in 22.1 vs. 37.0%, high triglycerides > or = 150 mg/dl in 26.6 vs. 30.6% and low HDL cholesterol < 40 mg/dl in 43.2 vs. 54.9%; while in women these were in 22.5 vs. 43.1%, 28.6 vs. 45.1%, 28.6 vs. 28.7% and 45.9 vs. 54.2% respectively. In the second study there was a significant increase in diabetes, obesity, hypertension (men), total- and LDL cholesterol and triglycerides and decrease in HDL cholesterol (p < 0.05). In the first study with increasing educational status a significant increase of obesity, total cholesterol, LDL cholesterol and triglycerides and decrease in smoking was observed. In the second study increasing education was associated with decrease in smoking, leisure-time physical inactivity, total and LDL cholesterol, and triglycerides and increase in obesity, truncal obesity and hypertension (Least-squares regression p < 0.05). Increase in smoking, diabetes and dyslipidaemias was greater in the less educated groups. CONCLUSIONS Significant increase in coronary risk factors--obesity, diabetes, total-, LDL-, and low HDL cholesterol, and triglycerides is seen in this urban Indian population over a seven year period. Smoking, diabetes and dyslipidaemias increased more in low educational status groups.

Abstract
The purpose of this study was to establish a set of normal values for inner intercanthal distance (IICD), interpupillary distance (IPD) and outer intercanthal distance (OICD) in a normal Indian population aged 3-80 years and to find whether the difference between the values of these parameters is statistically significant. We also aimed to compute a regression equation for calculating these. Two thousand five hundred clinically normal Indians were enrolled in the study. A millimeter scale was used to measure IPD and IICD. OICD was measured from the bar reading of Hertel's exophthalmometer. Statistical methods were used to calculate the mean and standard deviation values for these parameters. T-test was applied to determine whether difference between the mean values for these parameters in both sexes was statistically significant or not. A regression equation was also computed to find the values for these parameters in both sexes. The IICD, IPD and OICD ranges for males were 20-36 mm, 46-70 mm and 76-105 mm, and for females 20-36 mm, 46-75 mm and 71-105 mm, respectively The difference between the mean values for these parameters was statistically significant in some age groups but not in others. Gender did not usually influence the normal values for IICD, IPD and OICD in the Indian population. The normal values of these parameters were usually lower than those observed for other races. A knowledge of normal values in this population subgroup can help in studying orbito-cranial growth patterns, syndrome diagnosis, surgical management of cranio-facial deformities and trauma, and manufacture of spectacles.

Abstract
Fibrous histiocytoma, a mesenchymal tumor, although reported to develop in various ocular structures with a variable frequency, has never been found within a pterygium. We report the case of a 50-year-old female who had had a pterygium for the last six years and had developed a tumor within it one and a half years ago. The tumor was excised along with the pterygium. On histopathological examination the tumor was found to be a benign fibrous histiocytoma arising from within the pterygium.
