ABSTRACT
Background: It is the fact that, India consists of world’s largest tobacco chewer population, more prevalent in low income group. The effects of tobacco chewing on semen parameters have been widely studied. The study aim is to analyze the semen analysis parameters (oligozoospermia, asthenozoospermia, teratozoospermia, oligo-astheno-teratozoospermia -OATS and azoospermia) of tobacco chewer and non chewer infertile patients.Methods: A retrospective analysis of 639 patients was done out of which 150 were non-chewers and 489 were tobacco chewers. The percentage of population with particular semen abnormalities were compared between the two groups. The same comparison was performed between tobacco chewing primary infertility and secondary infertility patients in order to specifically assess the effect of tobacco chewing in sub-fertile patients.Results: OATS and azoospermia cases were significantly higher in the tobacco chewing infertile patients as compared to oligozoospermia, asthenozoospermia and teratozoospermia cases. In case of sub-fertile patients also, the percentage of OATS and azoospermia were significantly higher.Conclusions: This finding suggest that tobacco chewing greatly affects every parameter of sperm i.e. concentration, motility and morphology collectively. Moreover, tobacco chewing may be less affecting the male fertility initially but prolonged exposures affects detrimentally resulting in serious semen parameter abnormalities such as OATS and even azoospermia. And such cases are difficult to treat even with higher and advanced infertility treatment options like ICSI, microfludics, etc. This reduces the chances of IVF success as well as increases the financial burden on the patients undergoing infertility treatment. Thus, infertility clinics must employ awareness programs for such patients to explain them the effects of tobacco chewing habit and reducing it can definitely enhance the treatment outcomes.
ABSTRACT
Background: Male factors contribute to almost 50% of infertile couples. Deleterious effects of tobacco smoking on male reproductive system are well known. Research studies report contradictory findings about the effect of tobacco chewing on male fertility. Aim and objectives: To study effect of tobacco chewing on seminal parameters in male partners of infertile couples. Material and Methods: Present study was conducted on 100 male partners of infertile couples (50 tobacco chewers and 50 non-chewers) in age group of 21-40 years in the semen analysis laboratory in department of Physiology of Government Medical College, Nagpur from October 2014 to March 2016. Seminal parameters like volume of ejaculate, sperm count, sperm motility and motile sperm count were measured and compared in both groups. Result: Tobacco chewers had significantly lower values of all the seminal parameters as compared to non-chewers. Significantly low values of all parameters were observed in severe tobacco chewers as compared to mild and moderate tobacco chewers. Conclusion: Tobacco chewing has adverse effect on seminal parameters of male partners of infertile couples thus proving its pronounced role in male infertility. Severity of this effect increases as duration of tobacco chewing is prolonged.
ABSTRACT
Background: Salivary flow rate and pH may be altered by chewable tobacco, the habit which is becoming a threat for oral cancer epidemic. The objective of the study was to find out the relationship between alterations in resting salivary flow rate (RSFR) and pH, which are early signs of oral health deterioration, with different forms of chewing tobacco products. Methods: A total of 354 healthy male subjects, consuming any form of chewable tobacco, belonging to low socioeconomic areas of Karachi were selected for this cross sectional study. A questionnaire was used to collect demographic data and details of chewing habits (using since, pack/day, duration of exposure etc.). Resting saliva of every subject was collected for 5min and RSFR was expressed in ml/min. Salivary pH was determined by using pH strips (pH 0-14). Data was analyzed on SPSS version 20. Results: Of 354 subjects, 27.4% were gutka, 24.3% niswar, 24.3% paan and 24% multiple users with mean RSFR as 0.40±0.30, 0.65±0.32, 0.64±0.39 and 0.41±0.25 respectively. Mean resting salivary pH was 6.58±0.78 with the lowest pH; 6.16±0.65 in multiple users. RSFR and pH significantly decreased with increase in packs consumed/day, duration of exposure and duration of usage. Conclusion: A significant negative correlation was found between RSFR and pH with tobacco chewing.
ABSTRACT
BACKGROUND: Use of smokeless tobacco (SLT) is widely prevalent in India and Indian subcontinent. Cohort and case–control studies in India and elsewhere report excess mortality due to its use. OBJECTIVE: The aim was to estimate the SLT use‑attributable deaths in males and females, aged 35 years and older, in India. MATERIALS AND METHODS: Prevalence of SLT use in persons aged 35 years and older was obtained from the Global Adult Tobacco Survey in India and population size and deaths in the relevant age‑sex groups were obtained from UN estimates (2010 revision) for 2008. A meta‑relative risk (RR) based population attributable fraction was used to estimate attributable deaths in persons aged 35 years and older. A random effects model was used in the meta‑analysis on all‑cause mortality from SLT use in India including four cohort and one case–control study. The studies included in the meta‑analysis were adjusted for smoking, age and education. RESULTS: The prevalence of SLT use in India was 25.2% for men and 24.5% for women aged 35 years and older. RRs for females and males were 1.34 (1.27–1.42) and 1.17 (1.05–1.42), respectively. The number of deaths attributable to SLT use in India is estimated to be 368127 (217,076 women and 151,051 men), with nearly three‑fifth (60%) of these deaths occurring among women. CON CLUSION: SLT use caused over 350,000 deaths in India in 2010, and nearly three‑fifth of SLT use‑attributable deaths were among women in India. This calls for targeted public health intervention focusing on SLT products especially among women.

Background: Low birth weight (LBW) has been defined by the World Health Organization (WHO) as birth weight less than 2,500 grams. In India, 30-35% babies are LBW. LBW is closely associated with foetal and neonatal mortality as well as morbidity and has a very complex aetiology. Aims & Objective: The present study was undertaken with the objectives of ascertaining epidemiological determinants of LBW. Materials and Methods: A facility based case-control study was carried out in all the 3 tertiary hospitals of Ahmedabad Municipal Corporation during April-2012 to September-2012. A total of 100 cases weighing < 2.5 kg and controls weighing > 2.5 kg each were selected during the study period. Crude and adjusted odd’s ratio with 95% confidence interval was calculated. Multiple logistic regression was used to estimate independent effect of maternal characteristic on LBW. Results: A significant association was observed between LBW and maternal age at consummation < 20 years, maternal education, socio-economic status, inter-pregnancy interval, antenatal visit < 3, maternal height <145cm, pre-pregnancy maternal weight, habit of tobacco chewing, previous history of abortion and anaemia. These variables were further entered in multiple logistic regression model and factors such as maternal age at consummation < 20 years, inter-pregnancy interval, antenatal visit < 3, maternal height, pre-pregnancy maternal weight < 45 kg, habit of tobacco chewing, previous history of abortion and anaemia were found to be significant independent risk factor for LBW. Conclusion: For reducing LBW emphasis should be given on reducing teen age pregnancy, improving nutrition during adolescence, increasing coverage of antenatal visits, encouraging wider birth interval and avoiding tobacco chewing.
ABSTRACT
Largely oral cancers are preceded by potentially malignant lesions, which may appear as white or red patches on the oral mucosa. Leukoplakia is one of the most common epithelial precursors of oral squamous cell carcinoma. Speckled leukoplakia is a rare type of leukoplakia with a very high risk of premalignant growth and mortality rate. Though it is the common precancerous lesion, it poses a major diagnostic and therapeutic challenge. We present a rare case of bilateral recurrent speckled leukoplakia with malignant transformation and discuss this relatively rare entity in light of current information from the literature. We also attempt to present the clinical relevance, and the therapeutic modalities available for the management of the disease.
ABSTRACT
Background & objectives: Tobacco use among school children is becoming a serious problem in developing countries. The early age of initiation underscores the urgent need to intervene and protect this vulnerable group from falling prey to this addiction. The present study was thus undertaken to assess the prevalence of tobacco habits among school children, determine the age of initiation of these habits, and compare the age of initiation between students who were more than 15 and ≤ 15 yr of age. Methods: Data on tobacco use were collected from 4786 students of class 7 to 12 (age: 11-19 yr) studying in different private and government schools of Noida city during July- December 2005, through cluster and random sampling using a self-administered questionnaire. Results: Any kind of tobacco use was found in 537 (11.2%) students; 419 (8.8%) were ‘ever smokers (including current smokers)’ 219 (4.6%) were ‘ever tobacco chewers (including current chewers)’, 179 (3.7%) were ‘exclusive smokers’ and 118 (2.5%) were ‘exclusive tobacco chewers’. The mean age of initiation of these habits was around 12.4 yr. More than 50 per cent of tobacco chewers reported use of khaini at least once. Nearly 70 per cent of boys and 80 per cent of girls ≤ 15 yr initiated the habit of tobacco before the age of 11 yr. A significant early uptake of tobacco chewing was reported from private school students as compared to government school students (P<0.05). Interpretation & conclusions: Tobacco addiction is emerging as a big threat among children. Our findings indicate a recent downward shift in the age at initiation of tobacco uptake and rising prevalence among girls. Such data need to be collected from different parts of the country to develop anti-tobacco campaigns and take policy decision.
