ABSTRACT Context: Overhead throwing athletes consistently display significant bilateral differences in humeral retroversion (HRV). However, there is limited evidence regarding HRV asymmetries in tennis players despite similarities between the overhead throw and tennis serve. Objective: To determine if junior and collegiate tennis players demonstrate bilateral differences in HRV, and whether the magnitude of the side-to-side difference (HRVΔ) was similar across different age groups. Design: Cross-Sectional Study Setting: Field-Based Patients or Other Participants: Thirty-nine healthy tennis players were stratified into three age groups: Younger Juniors (n = 11; age = 14.5 ± 0.5 years), Older Juniors (n = 12; age = 17.1 ± 0.9 years), and Collegiate (n = 16; age = 19.6 ± 1.2 years). Main Outcome Measures: Three-trial means were calculated for HRV for the dominant and nondominant limbs, and HRVΔ was calculated by subtracting the mean of the nondominant side from the dominant side. Paired-sample t-tests were utilized to determine bilateral differences in HRV, while a one-way ANOVA was used to compare HRVΔ between groups. Results: For all three groups, HRV was significantly greater in the dominant arm compared to the nondominant arm (Younger Juniors: dominant = 62.8° ± 9.1° vs nondominant = 56.3° ± 6.8°, P = .039; Older Juniors: dominant = 75.5° ± 11.2° vs nondominant = 68.6° ± 14.2°, P = .043; Collegiate: dominant = 71.7° ± 8.5° vs nondominant = 61.2° ± 6.9°, P = .001). However, no significant differences were detected in HRVΔ when compared across age groups (P = .511). Conclusions: Consistent with studies involving overhead throwing athletes, tennis players demonstrated significantly greater measures of HRV in the dominant limb. Further, the development of HRV asymmetries appear to have occurred prior to the teenage years as no changes were observed in HRVΔ between age groups.

This was a descriptive type of cross sectional study among 522 garments workers as  respondents. It was aimed to identify morbidity pattern, duration of illness among garments  workers and also to determine treatment seeking behavior during illness. The socio-demographic  characteristics of the respondents were the points of investigations.  It was revealed from the findings that the mean age of the respondents were 23.1years. They  were mostly female (80%) and married (60%). About 60% respondents were found primarily  educated and no one found illiterate. 90% respondents were found from nucleated family. The  study shows 79% respondents were suffering from illness during the last 02 months and majority  suffers (18.6%) and (43.6%) were found among 26-30 years age groups and 21-25 years age  groups respectively. However, female sufferers were more (33.6%) than male (10%) in the 21-  25 years age groups. Moreover about 42% respondents were suffering for 1-2 weeks and 28.8  are suffering for less than 02 weeks. On the otherhands, Loose motion, Cough, and  Breathlessness were found prominent sign/symptoms among 38%, 29%, 28% sufferers  respectively. Diarrhoea, Common cold and Respiratory Tract Infections were found as  predominant diagnosis among 40.5%, 22.5% & 15.1% respondents respectively. Nevertheless  majority 56% were seeking treatment from LMAF doctors. Conclusion: The study findings  highlight awareness program among factory owners and garments workers towards preventing  infectious and chronic diseases as well as to undertake modern scientific treatment. Improved  health care facilities in the garments factory may be considered for early detection and treatment  of cases to avoid complications.

Abstract Background : To date, a few studies have documented the detailed periodontal conditions of a Japanese population. It is important to know if the awareness of Japanese nationals and dentists regarding oral hygiene and prevention of periodontal disease have improved when compared with the past in Japan for the development of future scenarios regarding prevention. The aim of this study was to investigate the severity, prevalence, and extent of periodontal disease in the adult population of the city of Takahagi, Japan. Results were also compared with those of an epidemiological study performed in Japan in the 1980s. Methods : A total of 582 (aged 20 to 89 years) randomly sampled Takahagi residents answered a comprehensive questionnaire and participated in clinical examinations. Results : The mean percentages of tooth surfaces harboring plaque and exhibiting BOP were 59.5 ± 24.9% and 31.1 ± 21.1%, respectively. The mean PPD and CAL were 2.5 ± 0.5 mm and 2.9 ± 1.0 mm, respectively. Compared with results of the 1980s survey, the mean percentages of plaque and bleeding on probing were lower in the current population. The mean CAL and prevalence of attachment loss of ³5 mm in some age groups were higher in the present study than in the 1980s study. There were no statistically significant differences with respect to mean probing depth between the 1980s and current age groups. Conclusions : Periodontal disease was still prevalent in the current Japanese population, even though some improvement occurred. Proper public health programs therefore need to be established.

Studies on pharmacovigilance (PV) activities in Nigeria focused on perceptions of PV among professional healthcare workers are described here. There is paucity of information on pharmacy students’ knowledge about PV activities. Hence, this study, evaluated the knowledge and perceptions of final year pharmacy students about PV activities using descriptive and inferential statistics. A cross sectional study was undertaken in three Nigerian universities with a pretested questionnaire during the period of January and February, 2016. The questionnaire included closed-ended questions on demographic variables and questions designed to achieve the objectives of the study. Data was analyzed with IBM SPSS Statistics 20 and presented in percentages, means, standard deviations and median at 50% percentile. The mean knowledge score of pharmacovigilance and adverse drug reporting for the final year students was 4.25±0.18. There were significant differences in the mean scores of knowledge domain by age groups 21-24 years 4.8±0.70, 25-30 years 6.2 ± 0.84 and >30 years 4.6±0.72 at p=0.001; gender: male 4.1±1.20 and female 4.4±0.98 at (p=0.0001) as well as the current universities attended as follows University 1 with a scrore of 5.1±1.03, University 2 had a mean score of 6.3±0.99 at p=0.0120 and University 3 with a mean score of 4.3±1.01 at p=0.012. Furthermore, significant difference exist in the mean values of pharmacovigilance knowledge between those who had taking some courses in pharmacovigilance (7.3± 0.22) and those who did not (4.7 ± 0.13) at p=0.0001. Generally, the students had inadequate knowledge of PV activities. Therefore, emphasis on relevant PV courses in their curriculum is necessary.Bangladesh Pharmaceutical Journal 20(1): 1-13, 2017

Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children.Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, and hyperopia), ages (4–7, 8-9, 10–12, and 13–17), and appropriateness for gestational age, respectively.Results. The mean age of the children was9.2±2.8(age range 4–17 years). The mean spheric equivalent was+0.3±1.7(range: (−10.0)–(+10.0) diopters). The mean birth weight and gestational age were2681.1±930.8grams (750–5000 grams) and37.2±3.7weeks (25–42 weeks). According to multinominal logistic regression analysis, children with myopia were more likely to have higher birth weights than emmetropic children (OR: 1.0, 95% CI: 1.000–1.001, andP=0.028). The hypermetropes were found to be significantly small for gestational age between 13 and 17 years of age.Conclusion. Birth weight and appropriateness for gestational age as birth parameters may have an impact on development of all types of refractive errors. The hypermetropic children tended to be small for gestational age.

Purpose. To investigate the refraction and ocular biometry characteristics and to examine the prevalence of refractive errors in preschool children aged 3 to 6 years in Shanghai, China. Methods. A school-based cross-sectional study was conducted in Jiading and Xuhui District, Shanghai, in 2013. We randomly selected 7 kindergartens in Jiading District and 10 kindergartens in Xuhui District, with a probability proportionate to size. The children underwent comprehensive eye examinations, including cycloplegic refraction and biometric measurements. Myopia, hyperopia, astigmatism were defined as spherical equivalent (SE) ≤ −0.50 D, SE ≥ +2.00 D, and cylindrical diopters ≤ −1.00 D. Results. The mean SE for 3- to 6-year-old children was +1.20 D (standard deviation [SD] 1.05), and the mean axial length (AL) was 22.29 mm (SD 0.73). The overall prevalence of myopia and astigmatism was 3.7% and 18.3%, respectively. No difference in prevalence of astigmatism was found across age groups. There was a statistically significant association between lower cylindrical diopters and higher spherical diopters (Spearman’s correlation: −0.21, P<0.001). Conclusion. Chinese children aged 3 to 6 years in the Shanghai area were mostly mildly hyperopic, with a low prevalence of myopia. Refractive astigmatism for children may be relatively stable throughout the preschool stage. Astigmatism was significantly associated with refractive error.

Background: Humeral retroversion in baseball players is greater in the dominant shoulder than in the nondominant shoulder. However, the site and severity of the humeral rotational deformity remain unclear. Purpose: To evaluate the site of side-to-side differences in humeral retroversion in baseball players and the severity of these changes through 3-dimensional computed tomographic (3D CT) bone models. Study Design: Cross-sectional study; Level of evidence, 3. Methods: From 2008 to 2014, we studied 25 baseball players (12 pitchers, 13 fielders) who underwent surgery for throwing-related injuries (shoulder injury, 15 players; elbow injury, 10 players). The mean age (±SD) at the time of surgery was 20.0 ± 5.9 years. A reconstructed 3D CT model of the entire humerus was divided into 15 segments of equal height (overall mean, 21.4 ± 1.0 mm). The side-to-side difference in humeral retroversion in each segment was calculated by superimposing the model of the dominant side over the mirror-image model of the nondominant side. Results: The overall mean increase in humeral retroversion was 13.0° ± 6.2° on the dominant side. Significant side-to-side differences in retroversion were present throughout the humerus. The largest side-to-side difference in humeral retroversion was seen at the insertions of the internal rotator muscles (2.5° ± 4.3°) and around the proximal physis (2.5° ± 1.4°). At the insertions of shoulder capsule and rotator cuff tendons, the superior half of the humeral head was more retroverted than the inferior half ( P < .0001). The side-to-side difference in humeral retroversion was significantly greater in the pitchers (16.2° ± 5.1°) than in the fielders (10.0° ± 5.7°) ( P = .009), particularly at the proximal physis. Conclusion: Baseball players exhibited significant side-to-side differences in humeral retroversion at multiple sites throughout the humerus, including the proximal humerus near the epiphyseal plate and at the insertions of the internal rotator muscles, the middle of the humeral shaft, and the distal third of the humerus. Therefore, the increased humeral retroversion at multiple sites throughout the humerus needs to be considered when we perform physical examinations, provide treatment, or undertake biomechanical studies for any throwing-related injuries.
