Background: Body mass index (BMI) is a good indicator for measurement of bone mineral density (BMD) which measures the density of minerals present in the bones using a special scan. BMD can be used to assess the strength of bones. Osteoporosis is a natural phenomenon of wear and tear. Obesity is an independent risk factor for low BMD. Dual-energy X-ray absorptiometry (DEXA) is the most accurate way to measure BMD. DEXA is a gold standard technique for diagnosing osteoporosis. Hence the current study was designed to study the effect of BMI on BMD. Methods: The present retrospective study was conducted on the patients who were referred to the Department of Radio diagnosis for DEXA scan were selected. Eighty 50-80 years old men who attended various departments were included. BMI was measured as weight in kilograms by height in meters square. BMD was assessed by DEXA scan. Results: Eighty men in the age group of 50-80 (62.46 ± 7.63) years were included in the study. All men underwent a standard BMD scans of femoral neck and lumbar vertebrae (L2-L4) using a DEXA scan. BMI (28.1 ± 4.93) kg/m 2 shows a highly significant positive correlation with BMD (171 ± -1.76 ± 1.71) SD, r = 0.53 p<0.01. Conclusions:The results suggest lower BMI is an important risk factor for the occurrence of low BMD. BMD can be used for screening test for osteoporosis.

Background: Personal protective equipment (PPE) limits the health care workers contact with all secretions or biological products. This study was planned to find gaps between use of PPE among the health care providers (HCPs). The objective of the study was to evaluate appropriate use of PPE among health care providers in tertiary centres Tamil Nadu.Methods: A cross sectional study was done during November 2014 to October 2015 in two tertiary health care institutions. All health care providers (Doctors, nurses and technicians) who had more than one year experience and gave informed consent were included. Data collected by pretested structured questionnaire. Data analysis was done using SPSS 20v and summarized by descriptive statistics. Proportion and Chi-square was calculated at 5% α.Results: HCPs included in the study were 1060. Among them, there were 412(38.9%) doctors, 550 (51.9%) nurses and 98 (9.2%) technicians. Among 862 HCPs who work outside the operation theatre (OT) and ICU, appropriate uses of PPE were only 156 (18.1%). It was high among doctors 109 (31.5%) followed by nurses 39 (9.3%) and technicians 8 (8.2%) which was statistically significant p=0.0001. HCPs working in OT and ICU were 423 and 183 respectively. Among HCPs working in OT, appropriate use of gloves, mask, apron, gown and hair cover was 100%. But the use of goggles and shoe cover was very low. The reasons for inappropriate use of PPE was non availability 562 (78%) followed by not aware of the importance 77 (11%).Conclusions: The study showed inappropriate use and lack of adequate knowledge on infection control practices emphasizing that periodic re-training is needed.

Background: Health care workers are at risk of acquiring life threatening blood borne infections through needle stick and sharp injuries (NSSI) in their work place. This study was planned to highlight some important factors responsible for NSSI and possible measures to reduce it. The objective of the study was to assess the factors associated with NSSI and reasons for under-reporting. Methods: A cross sectional study was done during November 2014 to April 2015 in two tertiary health care institutions. All health care providers (Doctors, nurses and lab technicians) who had more than one year experience and gave informed consent were included. Data collected by pretested structured questionnaire. Data analysis was done using SPSS 20v and summarized by descriptive statistics. Proportion and Chi-square was calculated at 5% α. Results: Among 950 health care providers (HCPS), 649 (68.3%) had NSSI during their carrier, 335 (35.3%) in last one year. Females 225 (67.2%) experienced more NSSI. This study shows that, 98 (29.3%) HCPs had sustained injury once. Among the doctors, 51.4% Anaesthetist (p=0.001) and its more among the nurses (38.4%) followed by doctors (36.6%) (p=0.002). NSSI was more common among HCP who work between 30-40 hrs (p=0.00001). Majority of them sustained injury while performing the procedure 134 (40%), commonest place of injury was OT 149 (44.5%) and commonest item responsible was hypodermic needle 141 (42.1%). Only 50 (14.9%) reported to the concerned authority and follow up action was taken. Conclusions: The study shows high prevalence of NSSI, emphasizing the need for safe measures for handling sharps to prevent transmission of infection.
