The objective of the study was to establish reference values for radiographic soft tissue indices of the hooves of apparently healthy Nigerian horses and to identify sex and age-related variations if any. Lateromedial radiographic examinations of the forelimb hooves of 52 apparently healthy Nigerian horses of both sexes aged young (1 – 5years), adult (6 – 10years) and old (11years and above) were carried out in the cross-sectional survey design. Radiographic soft tissue indices such as hoof wall distal phalanx distance (HWDPD), hoof wall proximal phalanx distance (HWPPD), coronary extensor distance (CED), sole depth (SD), hoof cup (HC), palmarocortical length (PCL) of the third phalanx, hoof wall angle (HWA), angle of third phalanx (AP3) and angle of rotation (AR) were measured and compared between sexes and among age groups. There was no significant sex variations in the indices investigated. However, the mean SD and HC showed age-related significant variation. The mean SD was only significantly (P less than 0.05) lower in old horses compared to young and adult horses. The mean values of HC were significantly (P less than 0.05) lower in adult and old horses compared to young horses. Radiographic morphometric indices assessed in this study may differ with those reported from other breeds, so they can be used in the future as reference values for diagnosis of laminitis in front feet of Nigerian horses.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.

Thickness Measurements

Skin fold thickness (SFT) measurement is a reliable, cheap, simple, noninvasive method of body fat estimation at all ages including the neonatal period.Objective. To determine reference values of biceps, triceps, subscapular, and suprailiac skinfold thickness measurements in term Nigerian newborns.Method. A prospective cross-sectional study over a six-month period (Dec 2010–May 2011) was carried out on term and healthy neonates delivered between 37 and 41 weeks. The anthropometric measurements were taken within the first 48 hours of life including the skinfold thickness. The skinfold thickness measurements were taken at four sites, namely, triceps, biceps, subscapular, and suprailiac, using Harpenden skinfold calipers. The mean of two readings was recorded.Result. A total of one thousand one hundred and sixty-eight neonates were studied. The birth weight ranged between 2000 g and 5000 g with a mean birth weight of the neonates at3259±470 g. The mean birth weight of the males (3339±0.45) was significantly higher than that of females (3200±0.44) (p<0.0001). Female neonates had higher mean values of triceps, subscapular, and suprailiac skinfold thickness (p<0.001, resp.) while male neonates had higher mean value of biceps skinfold thickness (p=0.008). Females also had higher mean values of the sum of skinfold thicknesses at all four sites and the sum at the two truncal sites at every stratified gestational age.Conclusions. The sex specific percentile chart developed for skinfold thickness measurements can be used to detect deviation from the reference population such that infants who are at risk of nutritional or health problems are identified early, and intervention is instituted promptly.

Age related differences in extension of future time perspective in motivational goals are studied at three socio-economic levels in a representative sample of the French speaking adult population in Belgium. The hypothesis of an inverted U-shaped relationship between age and extension of future time perspective is tested statistically. It cannot be maintained when using two indices of future extension that are borrowed from earlier studies in this field: (a) the proportion of number of references to the near future to the number of references to the distant future, and (b) the mean future extension score in number of years. The proportion of the mean future extension score to the statistically calculated expected life time is proposed as a new and better index of future extension for comparing different age groups. With this new index the hypothesis is confirmed at the three socioeconomic levels. The limits of the cross-sectional method that is used and the relative value of the new index of extension of future time perspective are discussed.

AbstractPurposeDevelop the first normative database of macular and circumpapillary scans with reference values at the level of the A-scan using the Heidelberg Spectralis Optical Coherence Tomography (OCT) machine.MethodsThis study is a retrospective cross sectional analysis of macular and circumpapillary OCT scans of healthy individuals. All participants had a full ophthalmic examination, including best corrected visual acuity, intraocular pressure, biomicroscopy, posterior segment examination and OCT scan. The volume and thickness of each of the nine Early Treatment Diabetic Retinopathy zones at the macula were analysed for the total retinal thickness, retinal nerve fibre layer (RNFL), ganglion cell layer (GCL) and inner plexiform layer (IPL). The thickness of the circumpapillary RNFL was analysed at the disc. De-identified A-scans were extracted from the OCT machine as separate tab-separated text file and made available according to the data sharing statement.ResultsTwo-hundred eyes from 144 participants were included of which 98 (49%) were female. The mean age (SD) was 48.52 (17.52). Participants were evenly distributed across four age groups and represented nine broad ethnic groups in proportions comparable to the local distribution. All the macular scans were 20° x 20° (5.9 mm x 5.9 mm), with a total scan density between 12,800 and 49,152 A-scans. The peripapillary scans were all 12° (3.5 mm), at a scan density of 768 A-scans. The mean retinal, GCL and IPL volumes were significantly greater in males than females. Age and total retinal volume (r = –0.2561), GCL volume (– 0.2911) and IPL volume (–0.3194) were negatively correlated. No significant correlation was found between the RNFL and age.ConclusionThis study provides a normative database of macular and circumpapillary scans with reference values at the level of the A-scan using the Heidelberg Spectralis Optical Coherence Tomography (OCT) machine.

Objective: This study was conducted to quantify the normal indices of anthropometric measures related to ophthalmology including Interpupillary distance (IPD), Inner canthal distance (ICD), Outer canthal distance (OCD) in a normal, healthy Pakistani population. Methods: This is a cross sectional study. Total 500 patients were chosen randomly but 499 were included in this study. Patients were selected randomly in an outpatient department of Jinnah Post Graduate Medical Centre Karachi, over the period of five months. IPD, ICD & OCD all measurements were taken with the help of plastic rule by only one researcher to minimize chances of error as much as possible. IPD was reconfirmed from auto refractometer while ICD and OCD readings were taken twice by occluding one eye of researcher to reduce error. Participants were divided into four categories on basis of: Age, Gender, ethnicity and geographical location. Patients were further categorized on basis of Ethnicity to Urdu Speaking, Sindhi, Punjabi, Pathan, and others. Moreover, four age groups were drawn ranging from 15-24 years, 25-44 years, 45-64 years and 65 years and greater. Results: Our study comprised a total of 499 patents of which 272(54.5%) were males, and 227(45.5%) were females. The mean age of the participants was 39.3 ± 14.5 years. The mean values for the IPD, ICD and OCD in mm were 61.8 ± 6.2, 30.9 ± 2.9 and 85.2 ± 6.6 respectively. A statistically significant difference was observed between IPD, ICD and OCD Indices among male and female study participants (p<0.001, p=0.043, p<0.001). While comparing the IPD, ICD and OCD indices amongst the different ethnic groups, we found no statistically significant difference (p=0.09. p=0.28, p=0.06). Overall, there was no correlation between the age and other variables i.e. IPD, ICD, OCD, (r = 0.07, p = 0.085), (r = 0.005, p = 0.906), (r = -0.08, p = 0.058). Conclusion: This work has recommended normative values of IPD, ICD and OCD in Pakistani population on the basis different variables including gender, age, and ethnicity.

Strength training is currently the most recommended primary therapeutic strategy to prevent and reverse the decline of muscle mass, strength, and functional deterioration associated with age. The aim is to provide reference values of handgrip strength (HGS) in the Basque Country population and compare the values with other populations. A total of 1869 subjects from the health-promoting programme for adults and older adults run by the Bilbao City Council were assessed using HGS with a digital dynamometer and anthropometric data measured by Tanita to obtain the mean values according to age distribution. From the 1869 subjects, 87.5% were women and 12.5% men. The HGS was higher among men than women, 32.4 ± 6.6 versus 20.1 ± 4.7 kg, respectively, p < 0.001 at all ages. Weak HGS cut-off points by age groups ranged from 31.0 to 23.8 and from 18.9 to 12.4 in men and women, respectively. The sample data were compared (d, t, and α) with those of other populations in all age groups (group > 60 years at 95% df, p < 0.05). A health-promoting programme appears to be effective in the general population in obtaining better values in the HGS test as age increases.

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

Background: The fallopian tubes act as conduit for spermatozoa to reach the oocyte and to convey the fertilized (egg) to enter the uterine cavity following fertilization. Problems with the fallopian tubes can lead to infertility. Detailed morphological and histological knowledge is essential for the diagnosis and management of fallopian tube disease.Objective: The purpose of the present study was to identify the inner diameter of ampulla of the fallopian tube and its changes with advancing age.Methodology: This descriptive cross-sectional study was conducted in the Department of Anatomy at Dhaka Medical College, Dhaka, Bangladesh from July 2008 to June 2009 for a period of one (01) year. This present study was performed on post mortem fallopian tubes of Bangladeshi female. Among them lowest age was 12 years and highest age was 50 years. Samples were divided into three differential age groups named asgroup A (10 to 13 years), group B (14 to 45 years), and group C (46 to 50 years). All samples were studied morphologically and histologically.Results: The mean inner diameter of the ampulla of the right and left fallopian tubes ranged from 1.99±0.08 to 3.24±0.27 mm. The difference between all the groups were statistically significant (p < 0.001).Conclusion: The mean difference of the inner diameter of the ampulla of the right and left fallopian tubesbetween groupA and groupB and groupB and groupC were statistically significant; however, there was no significant difference between right and left fallopian tube.Journal of National Institute of Neurosciences Bangladesh, 2018;4(2): 137-140

A cohort measurement of tibio-femoral angle (TFA) is more meaningful and reliable than a cross-sectional survey in investigating TFA pattern of development. This study reports the pattern of knee angle development in a cohort of 152 normal Nigerian children during the first 12 months of life. The infants’ tibio-femoral angle, inter-condylar, and inter-malleoli distances were measured at monthly intervals using clinical methods. Age-reference values were generated. Results showed that the developmental pattern of tibio-femoral angle is extreme varus at birth with values ranging from 5°to 25°. The mean varus at birth (13.2±3.7°) decreased to reach the lowest value (5.6±0.7°) at nine months and then rose slightly to (6.9±1.2°) at 12 months. None of the infants exhibited a measurable valgus angle. In conclusion, the chronological development of TFA in these cohort Nigerian infants was varus, maximal at birth and decreasing during first 12 months of life. The age-reference values herewith generated may serve as a useful guide in evaluating lower limb alignment in Nigerian children, age 0 to 12 months.

Purpose: To characterize the sex- and age-related alterations of the macular vascular geometry in a population of healthy eyes using fundus photography.Methods: A cross-sectional study was conducted with 610 eyes from 305 healthy subjects (136 men, 169 women) who underwent fundus photography examination and was divided into four age groups (G1 with age ≤ 25 years, G2 with age 26–35 years, G3 with age 36–45 years, and G4 with age ≥ 46 years). A self-developed automated retinal vasculature analysis system allowed segmentation and separate multiparametric quantification of the macular vascular network according to the Early Treatment Diabetic Retinopathy Study (ETDRS). Vessel fractal dimension (Df), vessel area rate (VAR), average vessel diameter (Dm), and vessel tortuosity (τn) were acquired and compared between sex and age groups.Results: There was no significant difference between the mean age of male and female subjects (32.706 ± 10.372 and 33.494 ± 10.620, respectively, p &gt; 0.05) and the mean age of both sexes in each age group (p &gt; 0.05). The Df, VAR, and Dm of the inner ring, the Df of the outer ring, and the Df and VAR of the whole macula were significantly greater in men than women (p &lt; 0.001, p &lt; 0.001, p &lt; 0.05, respectively). There was no significant change of τn between males and females (p &gt; 0.05). The Df, VAR, and Dm of the whole macula, the inner and outer rings associated negatively with age (p &lt; 0.001), whereas the τn showed no significant association with age (p &gt; 0.05). Comparison between age groups observed that Df started to decrease from G2 compared with G1 in the inner ring (p &lt; 0.05) and Df, VAR, and Dm all decreased from G3 compared with the younger groups in the whole macula, inner and outer rings (p &lt; 0.05).Conclusion: In the healthy subjects, macular vascular geometric parameters obtained from fundus photography showed that Df, VAR, and Dm are related to sex and age while τn is not. The baseline values of the macular vascular geometry were also acquired for both sexes and all age groups.
