Introduction: To study and compare the changes in the height of dermal papillae in the skin of different age groups in a segment of Pakistani population. Study Design: Cross sectional study. Period: Five months, from July 2010 to November 2010. Setting: Anatomy Department, Army Medical College, Rawalpindi. Materials & Method: Sixty volunteers of both sexes, after fulfilling the inclusion criteria, participated in this cross sectional study. They all gave written informed consent. They were divided into three equal groups according to their ages, Group A ranged in age from 18 – 29 years, Group B from 30 – 49 years, and Group C > 50 years. Punch biopsies were taken from the sun protected upper arm skin, from all volunteers, after giving local anaesthesia. Samples were stained with Hematoxylin and Eosin. They were observed under light microscope. Height of dermal papillae was measured at three random sites in each sample and mean was taken.The mean of all three groups was compared with each other and data was analyzed. Results: The mean of each sample was taken and then final mean of each group was calculated. They were then compared with each other. The mean height of dermal papillae of group A was 98.667µm, that of group B was 83.333µm and the mean height of dermal papillae in group C was 47.33µm. There was significant difference between the three groups and ‘p’-value was less than 0.5. Conclusion: At the end of this study, it was concluded that, the height of dermal papillae reduces significantly with age.

Introduction: Previous equipments used to study cornea were mostly Placido based which could only analyse anterior surface of cornea, while Pentacam is based on elevation based imaging method that helps to study the curvature of cornea, its elevation and thickness profile more accurately. There are numerous studies published to study the thickness of cornea, this study outlines the importance of changes introduced in various corneal parameters with age which in itself is an important factor with possible positive correlation. Aim: To determine various corneal parameters and to interpret the variations in these with increasing age. Materials and Methods: This cross-sectional study included a cohort of 60 healthy patients attending Outpatient Department of Ophthalmology from July 2019 to February 2020. Two sets of values were determined, studied and compared between different age groups. First set of values included, keratometry values in the flat (K1) and steep (K2) and maximal keratometry values of the front surface (Kmax). Second set of values included, Anterior Elevations (AE), Posterior Elevations (PE), PE minus AE from Best Fit Sphere of 8 mm (BFS) and PE from the Best-fit Toric Ellipsoid (BFTE), apex thickness (CCT), pachymetry at the thinnest-point thickness (TCT),average corneal Pachymetry Progression Indices (PPI avg) and average Ambrosio’s Relational Thickness indices (ART avg). Based on age, three groups were created with 20 participants in each, Group A with age 18 to 25 years, Group B with age between 26 and 40 years and Group C with age more than 40 years. Scanning of all study subjects was done using Pentacam. Mann-Whitney U test and Spearman correlation test were used for the statistical analysis. Results: The average age was 21±2.42 years in group A, 30.9±4.3 years in group B and 42.45±1.65 years in group C. When AE, PE and PE-AE values were compared among three age groups, results were highly significant with p-value <0.00001. Thus, the elevation indices from BFS were found to be correlated with age. On comparison of PPI average between group A and B, group B and C values were statistically insignificant (p-values 0.51 and 0.19, respectively).Though in comparison between Group A and C, average corneal PPI avg was found to be of statistical significance (p-value=0.048). Average ART indices (ART avg) was found to produce highly statistically significant results among 3 groups (p-value <0.00001). Conclusion: The corneal parameters are significantly altered from their normative values with age. This study outlines that elevations indices and avg ART values are significantly altered with increasing age.

Background: Blood pressure measurements in childhood are an important clinical examination. Present study was done to evaluate the normal range of blood pressure (BP) in children aged 6-12 years and to find its relationship with regard to age, sex, height and weight criteria and comparing the values with the available standards.Methods: This prospective cross-sectional study was done in primary and middle schools of Chennai from January 2016 to May 2017. Three readings of blood pressure were recorded for each subject and were correlated with age, gender, socioeconomic status and anthropometry. Data was analysed on SPSS 20.0. P value of <0.05 was considered significantResults: A total of 2002 children (1026 boys, 976 girls) of age between 6-12 years were examined over 18 months. There was an upward trend in both systolic (r = 0.437, P<0.001) and diastolic BP (r = 0.386, P <0.001) with age. There was no statistically significant difference in mean systolic and diastolic BP with gender (P = 0.10), weight (P = 0.10) and height (P = 0.10). There was a statistically significant difference between the mean systolic and diastolic BP between low and high socio-economic groups (P <0.0001). The proportion of children with hypertension was 9.54% with a slight female preponderance.Conclusions: Blood pressure measurement in children is pivotal in clinical examination. It shows a linear relationship with age and varies across socio-economic status. Periodic recording of BP would enable identify hypertension at an early age.

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

Introduction: Colour is believed to stimulate senses. It improves the attention span and helps in developing cognitive abilities and hence, can be beneficial in the educational set-up. There is a void in literature about usefulness of colours in the education settings in India. Aim: This study was conducted to assess students’ preference, perception, emotional responses, memory, and cognition related to colours. Materials and Methods: A cross-sectional study conducted over a period of two months (January-February 2018) comprised of 300 students divided into two equal groups: Group A with 13 to 18 years of age, Group B with 19 to 25 years of age. On four consecutive days, both the groups were exposed to the same power point slide with some words highlighted with a single colour (red: material related to discovery of earth’s polarity, blue: material related to arbovirus, yellow: material related to pathophysiology of diabetes mellitus, or green: material related to Mangalyan). At the end of the fourth session, a validated questionnaire was used to evaluate the students’ perceptions and responses to various colours. The data were analysed using R software v 3.6.1. The Kruskal-Wallis test was used to find significant differences within the group, p<0.05. Results: In group A, the highest mean preference was observed for the colour red (mean=8.02±2.83; p=2.20e-16), blue was found to be a soothing colour (n=65) and yellow helped in better recollection of facts (n=44). In contrast, in group B, the highest mean preference was observed for the colour blue (mean=8.35±3.59; p=5.90e-15). Yellow was considered a more soothing colour (n=43), and black helped in better recollection (n=41). Conclusion: Colour perception varies in different age groups. It also affects emotions, memory, and influences mood disposition.

Objectives: Alteration of smell and taste has been reported in patients with coronavirus disease 2019 (COVID-19). The incidence and clinical-symptomatic manifestation of COVID-19 is different between northern and southern Italy. This study aims to evaluate the onset of alteration of smell and taste in asymptomatic and symptomatic patients in Sicily (extreme south of Italy). Methods: This prospective cross-sectional study was performed on asymptomatic and symptomatic COVID-19 patients tested for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) from May 1 to May 15, 2020. A questionnaire was used for evaluating the prevalence of smell and taste disorders in COVID-19 patients before performing nasopharyngeal swab. Results: Of the total 292 patients, 242 (83.2%) were negative for SARS-CoV-2 and 50 were positive (16.8%). Twenty-six of the 50 (52%) SARS-CoV-2 positive patients reported smell/taste disorders. Twenty-eight of the 50 (57.1%) SARS-CoV-2 positive patients were hospitalized (group A), and 22 (42.9%) were nonhospitalized (group B). The mean age in group A and group B was 45.4 ± 13.7 years and 57.0 ± 15.0, respectively ( P = .007). The symptoms reported by hospitalized patients were fever (71.4%), cough (64.2%), fatigue (82.1%), and dyspnea (100%), while in nonhospitalized patients, the most reported symptoms were sore throat (72.7%), rhinorrhea (77.2%), and altered smell (81.8%). Anosmia/hyposmia reported in group A and group B was 28.5% and 81.8%, respectively ( P = .001). Conclusion: These preliminary results indicate that the majority of SARS-Cov-2 positive patients in southern Italy did not require hospitalization and presented with milder symptoms or no symptoms and the alterations in smell and taste occurred.
