Frequency and Risk Factors of Erectile Dysfunction among Bangladeshi Adult Men with Type 2 Diabetes Mellitus.

Various forms of sexual dysfunction occur in men with diabetes mellitus (DM) including disorders of libido, ejaculatory problems, and erectile dysfunction (ED). This cross sectional study was conducted in a tertiary hospital of Bangladesh from December 2017 to May 2018 to find out the frequency and risk factors of ED in subjects with type 2 DM (T2DM). One hundred fifty (150) consecutive male patients with T2DM attending the Endocrinology outpatient department (OPD) of the hospital during the study period were evaluated for the presence of ED by using the International Index of Erectile Function-5 (IIEF-5) questionnaire; their socio-demographic, anthropometric, and clinical data were also recorded. Glycemic status was assessed by measurement of fasting plasma glucose (FPG) and HbA1c. Morning serum testosterone was measured in all. Among 150 subjects 68(45.3%) had ED; ED was mild in 14.7%, mild to moderate in 18.0%, moderate in 6.0% whereas severe ED was present in 6.7% of the subjects. The subjects with ED had higher mean age, longer duration of DM, higher body mass index (BMI), higher HbA1c, higher FPG, higher serum creatinine, and lower serum testosterone level than those without ED. Study subjects in the higher age group and higher duration of DM had higher frequencies of ED. IIEF-5 score showed significant negative correlation with age, duration of DM, HbA1c, fasting plasma glucose, serum creatinine and significant positive correlation with serum testosterone. In logistic regression analysis, duration of DM and serum testosterone were found be independent predictors of ED. Frequency of ED among Bangladeshi type 2 diabetic males is high; duration of DM and serum testosterone are independent predictors of ED in them.

A simple risk estimates study for oral cavity cancer: practical approach in Indian context.

A study was conducted on 131 cases of oral cavity cancer (OCC), 145 cases of oral leucoplakia and 704 subjects without any oral lesions to investigate risk factors associated with the development of carcinoma of oral cavity in a hospital based cancer registry. Personal interviews, as well as physical examinations of the subjects enabled evaluation of a variety of potential risk factors. Potential risk factors like tobacco chewing, tobacco smoking, snuff dipping, alcohol consumption, bad oral and dental hygiene and age were given each certain numerical values. Each subject was first given a scoring and then analysed and correlated with the presenting lesions, when present. The study revealed that tobacco chewing and bad oral and dental hygiene contributed mainly to higher scoring. Among the subjects in high risk group (scoring more than 400) 63% had OCC, 21% had oral leucoplakia and 16% had no clinical oral lesions. Among the medium risk group (scoring between 100 and 400) 6% had OCC, 21% had leucoplakia and 73% had no oral lesions. In low risk group (scoring below 100) 8% had leucoplakia and 92% had no clinical oral lesions. Using the scoring system, it is suggested that the high risk group for OCC could be identified from general population and cancer detection tests could be specially directed towards this target group to detect maximum number of cases with minimum possible resources.

Isolation and characterization of a cellulase-free pectinolytic and hemicellulolytic thermophilic fungus.

A thermophilic fungus belonging to the Deuteromyces, having pectinase and xylanase activities, was grown at its optimum temperature of 55°C. It grew over a wide pH range of 4 to 10, being optimal at 6. The fungus grew well on modified Mandels' medium in which cellulose was substituted either with hemicellulose or pectin. With citrus pectin as carbon source, 121 units/ml of pectinase activity were obtained and with larch wood xylan as carbon source, 83 units/ml of xylanase activity were obtained.
