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.

Abstract Background This study aimed to identify the factors associated with smartphone addiction risk among preschool children. Thus far, little is known about these factors in younger children compared to older children or adolescents, although the age at first use of a smartphone is decreasing. Methods A cross-sectional study design was used. Data were obtained from the nationwide survey on smartphone overdependence conducted in 2017 in South Korea by the Ministry of Science and ICT and the National Information Society Agency. Data from 1,378 preschool children were analysed using binominal logistic regression analysis. This study complied with the Strengthening the Reporting of Observational Studies in Epidemiology. Results Of the samples, 17.1% showed a risk of smartphone addiction. The odds of high risk for smartphone addiction increased with the duration of smartphone use during the week and the frequency of smartphone use over the weekend. Using smartphones to watch TV shows and videos significantly increased the odds of smartphone addiction risk, whereas using smartphones for education and games did not. Conclusions The findings of the present study showed that, similar to children in other age groups, preschool children were also exposed to the risk of smartphone addiction. To reduce smartphone addiction risk in these children, parents should be aware of their risk of smartphone addiction and consider allowing their children less than 30 minutes of smartphone use during the week and more opportunities for physical activities especially over the weekend. Our findings also suggested that parent-centred education needs to be provided to correct parents’ perceptions. Information on smartphone addiction should be provided to parents along with an explanation that children’s smartphone use for educational purposes is beneficial; however, its use for the parents’ convenience or other purposes was not.

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.

Background: Pediatric glaucoma triggers refractive errors by modifying the biometry of the eye. This study was conducted with the objective of estimating the short-term biometric and refractive changes prior to and post trabeculectomy in pediatric glaucoma. Material and Methods: A 12-month, descriptive, cross-sectional study was carried out from January to December 2019, using patients operated on for pediatric glaucoma. Pre- and post-operative biometric and refraction measurements were noted. Visual acuity, axial length, corneal diameter and refraction were obtained. All ethical requirements (anonymity, free, informed, and continuous consent) were satisfied. Data analysis was done using SPSS 20.0. Results: In the present study, 47 eyes of 27 patients were surgically operated upon, from January 2019 to December 2019 at CHU-IOTA. The predominant sex was male (17 patients) at 63%, giving a sex ratio (M / F) of 1.7. The mean age was 5.04 ± 4.24. Preoperatively, the mean corneal diameter, and D90 were respectively 13.83 ± 1.51 and 12.55 ± 0.99. Preoperatively, the mean axial length, and D90, were 23.87 ± 1.29 and 22.28 ± 1.07, respectively. Preoperatively and at three month, the mean myopia (n = 36), were respectively -3.13 ± 1.83 and -1.59 ± 0.97. The mean preoperative astigmatism (n = 47) and D90 were respectively, -1.59 ± 0.77 and -1.23 ± 0.57. A statistically significant relationship (p <0.05) was found to exist between the preoperative and postoperative data of the axial length, corneal diameter, and refractive errors. Conclusions: Trabeculectomy significantly exerts a short-term positive impact on the biometrics and refraction by modifying the initial measurements and diopters.

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.

Abstract BACKGROUND Evidence suggests that sleep duration is related to blood pressure (BP), but the findings are still inconsistent for adolescents. OBJECTIVE To analyze the association between sleep duration and BP in Brazilian adolescents between 12 and 17 years of age. METHODS This study is part of the Study of Cardiovascular Risk in Adolescents (ERICA), a multicenter, school-based, cross-sectional study in 273 municipalities in Brazil. The sample consisted of 65,643 adolescents. Sleep duration was measured by a subjective method, and BP was measured by the oscillometric method. Multiple linear regression analyses were performed to evaluate the association between sleep duration and BP. RESULTS The mean sleep duration was 8.14 hours (± 1.40), with significant difference between the groups according to BP levels (P &lt; 0.0001). The mean systolic and diastolic BP were 110.59 (± 11.87) and 65.85 (± 7.94) mm Hg, respectively, in the group of adolescents. Sleep duration was significantly associated with BP. Each increase 1 hour in sleep was associated with BP reduction in both sexes combined (P &lt; 0.0001). Considering the effects of covariates, each increase 1 hour in sleep was associated with systolic BP (SBP) reduction among boys (P = 0.004) and SBP elevation among girls (P = 0.009), after full adjustment. CONCLUSION The results suggest that each increase in sleep duration was associated with SBP elevation among girls. Such findings may have important implications for cardiovascular health in adolescence.

Aim : The objectives of this study were to evaluate the severity of malocclusion and orthodontic treatment need in Bangladeshi young adults by using the Dental Aesthetic Index (DAI).Methods: This cross-sectional study was conducted at Government and private college of Dhaka and Netrokona, Bangladesh. A total of 405 students (from 17 to 25 years old) were selected by convenience sampling. Students wearing orthodontic appliance or reporting a history of orthodontic treatment were excluded from the study. Clinical examinations were conducted using the Dental Aesthetic Index (DAI). The chi-square test (x2) was used to compare malocclusion severity. The analysis of variance (ANOVA) test was used to compare the changes in DAI scores and the mean DAI scores between various age groups. The t test was used to compare the mean DAI scores between sex groups.Results: 405 college students were examined, 305(75.3%) were boys and 100(24.7%) were girls. Most of the  students 277(68.4%) had DAI scores ? 25 with no or little malocclusion requiring slight  or no  orthodontic  treatment, 76(18.8%) had DAI score of 26-30 with definite malocclusion requiring elective orthodontic  treatment, 34(8.4%) had DAI score of 31-35 with severe type of malocclusion requiring highly desirable orthodontic treatment, 18(4.4%) had DAI score ? 36 with very severe or handicapping malocclusion requiring mandatory orthodontic treatment.Conclusion: The majority of the students in our study (68.4%) required no or little treatment; (12.8%) had definite malocclusion requiring definite orthodontic treatment.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2

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
