Distress in infertile males in Manipal-India: a clinic based study

Background: Being infertile comes as an overwhelming realization for couples trying to conceive. In consideration of rising rates of infertility worldwide, clinicians in India have also begun exploring this field for new possibilities, development and research. The purpose of this study was to estimate the proportion and predictors of infertility specific stress in males diagnosed with primary infertility

Methods: This cross-sectional research was conducted in an assisted reproduction center, Manipal, India, on 300 infertile married males. The tools were "semi-structured questionnaire" compiled by the authors, "ICD-10 Classification of Mental and Behavioural Disorders [Clinical Descriptions and Diagnostic Guidelines] and " Psychological Evaluation Test for infertility. Multiple logistic regression analysis was carried out on data with p-value fixed as 0.05

Results: The presence of stress was reported in 72% of male participants. The predictors of stress were nature and severity of their infertility diagnosis, sperm defects, urological condition and experience of corrective surgery undergone for it. Psychological stress in men was also predicted by present and past history of significant psychiatric morbidity and coping difficulties associated with it

Conclusion: The stress is both a common experience and at times a clinical condition associated with deteriorating mental and physical health in men seeking fertility treatments. As a prerequisite, Indian fertility clinics need to treat stress as an identifiable condition and devise ways of addressing it at all stages of assisted conception and reproductive treatments

Determinants of Prakriti, the Human Constitution Types of Indian Traditional Medicine and its Correlation with Contemporary Science.

Background: Constitutional type of an individual or prakriti is the basic clinical denominator in Ayurveda, which defines physical, physiological, and psychological traits of an individual and is the template for individualized diet, lifestyle counseling, and treatment. The large number of phenotype description by prakriti determination is based on the knowledge and experience of the assessor, and hence subject to inherent variations and interpretations. Objective: In this study we have attempted to relate dominant prakriti attribute to body mass index (BMI) of individuals by assessing an acceptable tool to provide the quantitative measure to the currently qualitative ayurvedic prakriti determination. Materials and Methods: The study is cross sectional, multicentered, and prakriti assessment of a total of 3416 subjects was undertaken. Healthy male, nonsmoking, nonalcoholic volunteers between the age group of 20-30 were screened for their prakriti after obtaining written consent to participate in the study. The prakriti was determined on the phenotype description of ayurvedic texts and simultaneously by the use of a computer‑aided prakriti assessment tool. Kappa statistical analysis was employed to validate the prakriti assessment and Chi‑square, Cramer’s V test to determine the relatedness in the dominant prakriti to various attributes. Results: We found 80% concordance between ayurvedic physician and software in predicting the prakriti of an individual. The kappa value of 0.77 showed moderate agreement in prakriti assessment. We observed a significant correlations of dominant prakriti to place of birth and BMI with Chi‑square, P < 0.01 (Cramer’s V‑value of 0.156 and 0.368, respectively). Conclusion: The present study attempts to integrate knowledge of traditional ayurvedic concepts with the contemporary science. We have demonstrated analysis of prakriti classification and its association with BMI and place of birth with the implications to one of the ways for human classification.

Isolation of Mycobacterium bovis & M. tuberculosis from cattle of some farms in north India--possible relevance in human health.

BACKGROUND & OBJECTIVE: Infection due to Mycobacterium bovis typically occurs in cattle and animals transmit infection to each other. The choice of appropriate clinical specimen is very important for isolation of M. bovis and M. tuberculosis from cattle. The present study reports the isolation of M. tuberculosis and M. bovis from different types of specimens from cattle suspected to be suffering from tuberculosis in certain organized cattle farms in north India. METHODS: A total of 768 specimens (heparinized or EDTA containing blood (162), fine needle aspirates from prescapular lymph gland (PSLG,160), milk (154), pharyngeal swab (PhS, 98), rectal pinch (RP, 97) and faecal sample (97) from 161 cattle of organized cattle farms in north India suspected to be suffering from tuberculosis were analyzed. After decontamination by modified Petroff's method isolation of M.tuberculosis complex was done on Lowenstein-Jensen medium (with and without pyruvate). The culture isolates were identified as M. tuberculosis and M. bovis on the basis of biochemical tests. RESULTS: A total of 54 M. tuberculosis complex isolates were obtained, of them 40 were identified as M.bovis and 14 as M. tuberculosis. M.bovis were isolated from 12 of 38 animals in group A (Tuberculin +ve with signs of tuberculosis), 7 of 37 animals in group B (Tuberculin +ve and apparently healthy), 9 of 21 group C animals in (Tuberculin -ve with clinical signs of tuberculosis), 4 of 26 animals in group D (Tuberculin -ve and apparently healthy), 4 of 27 group E animals (having non-mycobacterial infection) and 4 of 12 animals in group F (having clinical signs such as debilitated condition, cough, decreasing milk production, etc). Maximum number of M. bovis (19/40, 47.5%) and M. tuberculosis (5/14, 35.7%) isolates were grown from prescapular lymph gland biopsy (PSLG) followed by blood from which 9/40 (22.5%) M. bovis and 4/14 (28.5%) M. tuberculosis were isolated. M. bovis [6/40(15%)] and M. tuberculosis [4/14(28.5%)] were also isolated from milk. Only 3/40 (7.5%) isolates of M.bovis could be isolated from 97 rectal pinch followed by 98 pharyngeal swab 2/40 (5%) and 97 fecal samples 1/40 (2.5%) while 1/14 (7.1%) M.tuberculosis isolates were obtained from pharyngeal swab. INTERPRETATION & CONCLUSION: Among the samples analyzed, PSLG was found to be most suitable specimen for isolation of M. tuberculosis complex from cattle and is thus of diagnostic importance. M. bovis in milk indicates the need to investigate the transmission to human in such settings. Isolation of M. bovis and/or M. tuberculosis from apparently healthy cattle indicates sub-clinical infection in the herd. Further, isolation of a significant number of M. tuberculosis from cattle suggests possible human-to-cattle transmission which need to be confirmed by prospective studies including tools like DNA fingerprinting.

Skeletal muscle mitochondrial dysfunction & diabetes.

Skeletal muscle insulin resistance is a key contributor to the pathophysiology of type 2 diabetes. Recent studies have shown that insulin resistance in a variety of conditions including type 2 diabetes, ageing and in offspring of type 2 diabetes is associated with muscle mitochondrial dysfunction. The important question is whether insulin resistance results from muscle mitochondrial dysfunction or vise versa. Gene array studies from muscle biopsy samples showed that transcript levels of several genes, especially OXPHOS genes are altered in type 2 diabetic patients during poor glycaemic control but many of these alterations are normalized by insulin treatment suggesting that reduced insulin action is a factor involved in muscle mitochondrial dysfunction. Moreover, insulin infusion while maintaining glucose and amino acid levels results in increase in muscle mitochondrial gene transcript levels and ATP production indicating that insulin is a key regulator of muscle mitochondrial biogenesis. At a similar post-absorptive insulin levels both type 2 diabetic patients and non diabetic controls have similar muscle mitochondrial ATP production but increasing insulin from low to high levels stimulate ATP production only in non diabetic people but not in the diabetic people. The lack of muscle mitochondrial response to insulin in type 2 diabetic patients is likely to be related to insulin resistance and reduced substrate utilization.

Association of obesity and insulin resistance with dyslipidemia in Indian women with polycystic ovarian syndrome.

BACKGROUND: Dyslipidemia, diabetes and obesity are all potent cardiovascular risk factors that tend to cluster in women with polycystic ovary syndrome (PCOS). Metabolic disorders in patients with PCOS cannot be explained solely by the presence of obesity. OBJECTIVE: To study the correlation between insulin resistance and serum lipid profile in Indian women with PCOS. SETTING: Gynecology clinic of a tertiary care hospital. MATERIALS AND METHODS: In this prospective study done from April 2004 to December 2004, 65 women with PCOS had their body mass index (BMI) and waist hip ratio calculated. Fasting glucose, insulin and lipid profiles were also estimated in each case. Insulin resistance was defined by fasting glucose-to-insulin ratio <or=4.5. The association of obesity markers and insulin resistance with lipid parameters was then studied. Statistical analysis using student 't' and Mann Whitney U tests was done as indicated. RESULTS: Insulin resistance was seen in 50 of the 65 PCOS women. There was no correlation seen between markers of obesity such as BMI and waist/hip ratio with various lipid parameters. But in PCOS women with insulin resistance, the lipid profile was significantly different [high triglycerides, total cholesterol and lower high-density lipoprotein (HDL)] compared to insulin-sensitive women. The difference between the two groups for total cholesterol (P = 0.002), triglycerides (P =or<0.001) and HDL (P <or=0.001) was statistically significant but that for low-density lipoprotein (LDL) (P <or=0.07) was not statistically significant. CONCLUSION: Insulin resistance is associated with dyslipidemia in women with PCOS, independent of obesity.

Efficacy and tolerability of trandolapril in mild to moderate hypertension--a double blind comparative clinical trial with enalapril in Indian population.

Several large scale clinical trials have demonstrated that angiotensin converting enzyme inhibitors offer cardiovascular and renal protection independent of their effects on systolic BP. Trandolapril is a new angiotensin converting enzyme inhibitor approved for the treatment of hypertension. The potential advantages of this drug are long duration of action and better tolerability. The objective of the study was to compare the efficacy and tolerability of trandolapril with that of enalapril in mild to moderate hypertension in Indian population. In this double blind, multicentric, parallel comparative clinical study, 120 patients with mild to moderate hypertension were randomly assigned to receive trandolapril 2 mg or enalapril 5 mg once daily for 8 weeks. The attainment of sitting diastolic blood pressure <90 mmHg at the end of 8th week was considered as primary outcome measure and attainment of diastolic blood pressure <90 mmHg or reduction of at least 10 mmHg diastolic blood pressure compared to baseline at any visit was considered as secondary outcome measures. 98.4% patients treated with trandolapril and 92.6% patients treated with enalapril fulfilled the primary outcome measure. 54, 72 and 62% patients on trandolapril and 52, 61 & 64% patients on enalapril fulfilled secondary outcome measure at the end of 2nd, 4th and 8th week respectively. Also trandolapril was better tolerated than enalapril with no significant abnormality in lab parameters.

Dermatoses among paddy field workers--a descriptive, cross-sectional pilot study.

BACKGROUND: Paddy farming is one of the main occupations in coastal South India. Dermatological problems in paddy field workers have not received much attention. AIM: The purpose of this study was to study the dermatoses of the exposed parts of the body, viz. face, hands, and feet, in paddy field workers. METHODS: Three hundred and forty-one workers were questioned and clinical findings noted. Scrapings for bacterial and fungal examination were taken by random selection. RESULTS: Seventy-three per cent had work-related itching. Melasma was the commonest facial lesion (41.1%). The main problems on the hands were hyperkeratosis (26.4%), nail dystrophy (15.2%) and paronychia (8.8%). Common feet dermatoses included nail dystrophy (57.1%), pitted keratolysis (42.5%) and fissuring (23.5%). Common aerobic and anaerobic bacteria isolated from pitted keratolysis and intertrigo were Klebsiella and Clostridium species. Aspergillus species were the commonest fungus grown from intertrigo. CONCLUSIONS: Occupational dermatoses are common in paddy field workers.

Periodontal diseases and awareness among patients.

Awareness of periodontal problems and how they interpret this and their timely intervention affects periodontal health. Many people neither recognize the symptoms of periodontal disease nor do they associate existing symptoms with the disease. Hence one should ensure that the routes of science transfer are open so that the appropriate knowledge regarding the prevention and control of periodontal diseases are available to the public.

Diabetes in old age: an emerging epidemic.

Diabetes in the elderly is emerging as one of the most important public health problems of the 21st century. In developing countries, the majority of people with diabetes are in the age range of 45-64 years. A better understanding on the pathogenesis of diabetes in the aging population is required to successfully treat and prevent its devastating complications. Changes in body composition with accumulation of fat in the abdomen is a key factor in the causation of diabetes in the aging population. The size and strength of skeletal muscle, a major tissue involved in glucose metabolism, also declines leading to muscle weakness and a reduction in physical activity. These changes lead to marked reduction in energy expenditure and abdominal fat accumulation causing insulin resistance. Recent evidence suggests that four months of aerobic exercise can improve muscle oxidative capacity similarly in younger and older people, but that insulin sensitivity is less likely to improve in older people. It appears that older people need to exercise more frequently to improve their insulin sensitivity. Diagnosis and management of diabetes in the elderly requires special attention since age, genetics, body composition and lifestyle factors all interact. Increasing evidence suggests that postprandial hyperglycemia is more sensitive to diagnose diabetes in elderly people than in the young. Age related changes in body function and cognition demand special caution in the selection of hypoglycemic drugs in the elderly. Targets of diabetes therapy in the elderly have to be individualized, considering the age of the patient, remaining life-expectancy and severity of co-morbid conditions. Short acting insulin secretogogues are preferred to avoid prolonged and frequent hypoglycemia. Judicious choice of insulin sensitizers, timely introduction of insulin, meticulous control of hypertension and hyperlipidemia are critical to prevent complications.

Acute respiratory infections in children: a community based longitudinal study in south India.

A community based longitudinal study was conducted in Malpe, a coastal village of Udupi district, Karnataka state, to investigate acute respiratory infections (ARI) in children. A cohort of 91 children under 3 years of age were followed up for 1 year, leading to 2047 fortnightly observation. On an average every child had 11.3 months of follow up. The overall incidence of ARI was 6.42 episodes per child per year. On an average each episode lasted for 5.06 days. Mean duration of ARI during one year was 32.5 days per child. Most of the ARI episodes in children (91.3%) were of simple Cough & Cold (no pneumonia). However, 8.2% developed pneumonia and only 0.51% had severe pneumonia. Incidence of ARI was almost same in male and female children. There was no significant difference in incidence among various age groups. But the incidence of pneumonia was significantly higher among infants (p<0.00002). Children of poor housing with smoke producing conditions suffered more frequently (p,002).

Influence of pre-pregnancy weight, maternal height and weight gain during pregnancy on birth weight

To study the effect of pre-pregnancy weight, maternal height and weight gain during pregnancy on birth weight. Design: A community based longitudinal study. Setting: The study was conducted in the rural field practice area of the Department of Community Medicine, Kasturba Medical College, Manipal, Karnataka State, India. Study Period: Between 1st June 1996 to 31st January 1998. Subjects: A total of 75 pregnancies were followed up till delivery. Main outcome and measures: Pre-pregnancy weight, maternal height, weight gain during pregnancy and other baseline characteristics were collected using a pre-tested proforma. Weight of the baby was recorded immediately after birth. The mean pre-pregnancy weight and maternal height were 43.7 kg [SD=6.6] and 154.2 cm [SD=5.2] respectively. The mean weight gain during pregnancy was found to be 8.0 kg [SD=2.6]. The mean birth weight was 2869.7 gm [SD=467.2] with a range of 1380-3800gm. A statistically significant correlation was observed between pre-pregnancy weight [r =0.4, p<0.001], maternal height [r=0.36, p=0.001], weight gain during pregnancy [r=0.52, p<0.001] and birth weight. Interpretation and Multiple regression analysis revealed that pre-pregnancy weight, maternal height and weight gain during pregnancy were independently associated with birth weight

Identification of risk factors for specific subsites within the oral and oropharyngeal region--a study of 647 cancer patients.

Studies on site specific risks for oral cancers are few. Present investigation explores the possible role of human sociodemographic factors in causing oral cancer. Majority of patients had poor oral hygiene (85.5%) and belonged to 51-60 years age group (35.7%). Most of the subjects were agriculture workers (30.3%). Tongue and floor of mouth included majority of the affected sites (77.2%). Male to female ratio was highest for tonsil (32.3%) but differed marginally for other subsites. Majority of females used tobacco (81%) while males users of tobacco, alcohol and smoking reported in nearly equal proportions. Tobacco and smoking were found as primary risk factors for several intraoral subsites. However, for tongue, palate and lip no risk factor could be identified from given patients' characteristics. In general, tobacco posed high risk for buccal mucosa and alveolus in comparison to other subsites. Smoking affected tonsil and floor of mouth more than other sites. Alcohol posed more risk for buccal mucosa and floor of mouth than tongue.

Asymptomatic bacteriuria in school children.

We studied 2447 asymptomatic school children by microscopic examination of urine and culture of a clear voided midstream specimen of urine. Only three children had bacteriuria (0.12%). Urographic abnormalities were detected in both the cases, which could be investigated. This study has shown that asymptomatic bacteriuria is comparatively rare in our community; however where there is bacteriuria, renal damage is common.
