Context: Arm span is the most reliable body parameter for predicting the stature of an individual.It is useful in predicting age related loss in stature and in identifying individuals with disproportionate growth abnormalities and skeletal dysplasias. Since in Bangladesh variegated ethnic groups inhabit in different climatic, nutritional and ecological conditions, no single anthropometric formula is suitable. The present study was undertaken to measure the stature, as well as arm-span and to determine whether there is any correlation between the stature and the arm-span. And to estimate using respective multiplication factors the stature from arm span and to assess the effectiveness of the above estimation by comparing the ‘estimated’ values with the ‘measured’ values. Study Design : Cross sectional descriptive type of study. Materials and Method: The study was carried out with a total number of 100 Christian Garo adult female aged between 25 to 45 years. Arm-span along with their stature was measured directly from the subjects by using anthropometric technique by a measuring tape. The data were then statistically analyzed by computation to find out its normative value. Multiplication factors were estimated for estimating stature and comparison were made between measured and estimated stature using paired "t" test. Result : The mean normal values of the arm-span is 154.74 (±5.69) cm and the stature 152.79 (±5.62) cm were found. The multiplication factor was estimated for the same hand measurements with the stature. Significant positive correlation was found in case of arm-span with the stature (r =0.89).

Background Arm span is the most reliable anthropometric measurement to predict the stature of an individual. Age and sex have to be taken into account to the best to predict height from arm span. It is useful in predicting age related loss in stature and in identifying individuals with disproportionate growth abnormalities and skeletal dysplasia. Objective The present study was under taken to measure the stature as well as arm span and to determine whether there is any correlation between the stature and the arm span Method This cross sectional type of descriptive study was carried out with a total number of 400 Nepalese adult population consisting of 225 Nepalese male adults and 175 female adults aged between 25 to 45 years. Stature and arm span were measured directly from the subjects by using anthropometric technique by a measuring tape. The data taken were statistically analyzed by computation to find out its normative value. The relationship between body height and arm span were determined using simple correlation coefficients. Then a linear regression analysis was performed to examine the extent to which arm span can readily predict body height Results The results have shown male of Birgunj are 167.39± 6.170 cm tall and have arm span of 168.01±7.659 cm, while female of Birgunj are 155.61±6.894 cm and have arm span of 159.25±6..362cm. The results obtained are substantially alike in other populations, since arm span was too close to body heights in male and greater in female. Conclusion The body height and arm span correlates well in males but not in females. This confirms the necessity for developing separate height models for each population and different sex.

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.

Introduction: Because of the availability of modern health facilities and moderately easy access to health services in the last 25 years, the blindness due to cataract and trachoma is expected to decline in Nepal. So it is felt that the causes of blindness need to be revised. Objective: To regroup the disease pattern leading to permanent blindness in patients attending a suburban multidisciplinary community-based hospital of Nepal. Materials and methods: A cross-sectional, descriptive study was conducted in patients attending Dhulikhel hospital over a period of 12 months, from March 2010. Only the patients with best corrected visual acuity of < 3/60 were enrolled in the study. A detailed ocular examination was carried out. Results: A total of 76 eyes of 58 patients were analyzed. Of all, 32 were male (55.2 %). The mean age of the patients was 43.03 ± 22.98, with a range of 7 years to 84 years. Retinal diseases had the higher prevalence (23, 39.7 %) followed by amblyopia (10, 17.2 %) and corneal diseases (9, 15.51 %). Anisometropic amblyopia (3.94 %) was the commonest type of amblyopia. Retinitis pigmentosa (9.21 %) and age-related macular degeneration (7.89 %) were common retinal diseases whereas anterior staphyloma (5.26 %) and leucoma (3.94 %) were common corneal diseases. Other important and rare causes of blindness included ethambutol-induced optic neuropathy and vitelliform dystrophy. Conclusion: Periodic collection of statistics on the relative frequency of the causes of blindness is important in socioeconomically developing nations like Nepal. This helps to revise the pattern of blinding diseases so that priorities can be redefined. Nepal J Ophthalmol 2013; 5(9):50-56 DOI: http://dx.doi.org/10.3126/nepjoph.v5i1.7822

Abstract Background Age-related deposition of fat in skeletal muscle is associated with functional limitations. Skeletal muscle fat may be present in people with preserved muscle mass or accompanied by muscle wasting. However, it is not clear if the association between muscle fat deposition and physical performance is moderated by muscle mass. Objective To determine whether the association between midthigh intermuscular fat and physical performance is moderated by muscle area. Methods We performed a cross-sectional analysis of the Health, Aging, and, Body Composition (ABC) study data collected in 2002–2003 (n = 1897, women: 52.2%). Midthigh muscle cross-sectional area (by computed tomography) and physical performance measures were compared across quartiles of intermuscular fat absolute area. Moderation analysis was performed to determine the conditional effect of intermuscular fat on physical performance as a function of muscle area. Conditional effects were evaluated at three levels of muscle area (mean and ± 1 standard deviation [SD]; 213.2 ± 53.2 cm2). Results Simple slope analysis showed that the negative association between intermuscular fat area (cm2) and leg strength (N·m) was of greater magnitude (beta coefficient [b], 95% confidence interval [CI] = −0.288 [−0.427, −0.148]) in participants with greater muscle area (ie, 1 SD above the mean) compared to those with lower muscle area (ie, at mean [b = −0.12 {−0.248, 0.008}] or 1 SD below the mean [b = 0.048 {−0.122, 0.217}]). Similarly, the negative association of intermuscular fat with 400-m walk speed (m/s) and chair stand (seconds) was greater in those with higher muscle areas (p &lt; .001) compared to those with lower muscle areas. Conclusions The association between higher intermuscular fat area and impaired physical function in aging is moderated by muscle area.

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.

BACKGROUND Internal thoracic artery (ITA) is the ideal graft material for coronary artery bypass grafting (CABG). It’s structural characteristics and resistance to atherosclerotic changes make it ideal for this. It is in this scenario that we attempted to study the histological characteristics and age-related changes. METHODS This cross-sectional study was done on stained slides of segments of ITAs obtained from 100 fresh cadavers during autopsy. Age range was between 20 – 80 years. The segments were collected at various rib levels constituting proximal, middle and distal segments. The wall parameters were measured and recorded. The specimens were grouped according to age into six groups with intervals of 10 years and analysis of variance (ANOVA) test were conducted on the samples using Statistical Package for Social Science (SPSS) software. RESULTS The mean thickness of tunica intima in the proximal segment of 100 specimens was 26.792 µm, tunica media was 171.437µm and the thickness increased significantly with age with (F = 33.038, P = 0.00), (F = 87.910, P = 0.00) respectively. In one specimen, the intimal thickening increased to 96.325 µm. The mean thickness of tunica intima in the middle segment was 19.665 µm, tunica media was 172.302 µm and it increased significantly with age with (F = 71.885, P = 0.00), (F = 85.481, P = 0.00) respectively. The mean thickness of tunica intima in the distal segment was 18.157 µm, tunica media was 146.278 µm and it increased significantly with age (F = 58.847, P = 0.00), (F = 66.137, P = 0.00) respectively. The intima media ratio (IMR) increased significantly with age. The IMR of proximal segment of 2 % specimens were found to be greater than 0.25 indicating atherosclerosis. The vessel wall parameters decreased from proximal to distal segments. CONCLUSIONS The vessel wall thickness and IMR was found to increase with age. The incidence of atherosclerosis was 2 % and in old age. It is clear that the ITA is the ideal graft for CABG in younger individuals. An understanding of these attributes of ITA will be helpful to the cardiothoracic surgeons. Moreover, the results of this study throw light on the vessel wall changes in the population of present times. Further clinical study is needed to assess the effect of other risk factors.

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.

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

AbstractGene–environment correlation (rGE) exists both within and between families. Between families, accumulating rGE has been used to explain dramatic changes in phenotypic means over time. The Dickens and Flynn model of increases in cognitive ability over generational time, for example, suggests that small changes in phenotype can lead to subsequent reallocation of environmental resources. This process sets up a reciprocal feedback loop between phenotype and environment, producing accumulating rGE that can cause large changes in the mean of ability, even though ability remains highly heritable in cross-sectional data. We report simulations suggesting that similar processes may operate within twin and sibling pairs. Especially in dizygotic twins and siblings, small differences in phenotype can become associated with reallocations of environmental resources within families. We show that phenotype–environment effects can account for age-related increases in rGE, rapid differentiation of siblings raised together, and widely reported increases in the heritability of behavior during childhood and adolescence.

Introduction: Arm span and hand length can be used for the estimation of an individual stature. Arm span, hand length, foot length, head circumference etc. have been proved to be useful to correctly estimate the height of a person. It can be useful in various medico legal purposes. Objectives: The present study was undertaken to find the correlation between the arm-span and hand length with the standing height of both males and females and to derive regression equations for estimation of their height. Materials and Method: This cross sectional type of descriptive study was carried out with a total number of 200 Nepalese medical students consisting of 120 male and 80 female aged between 18 to 24 years. Stature, arm span and hand length were measured directly from the subjects by using anthropometric technique by a measuring tape and a spreading caliper. The data taken were statistically analyzed by computation. The relationship between body height, arm span and hand length were determined using simple correlation coefficients. Result and Conclusion: In this study, the correlation between the arm-span and hand length with the standing height of both males and females was found to be an accurate predictor of the height and regression formulae were derived for calculating the height of male or female with the arm-span and hand length.
