    Introduction: Humerus is a long bone that contributes significantly to the total height of an individual. It is sexually dimorphic and is a well-preserved bone postmortem. Height and sex are essential in establishing one’s identity and can be estimated from long bones when standing height cannot be easily obtained. Previous studies report that sex and height are population-specific. Hence, the present study sought to establish the relationship between percutaneous humeral lengths and height and formulate models for height and sex determination for the Ghanaian population. Materials and methods: Measurement of standing height and percutaneous humeral lengths were taken from 286 Ghanaian consented participants with no noticeable lower and upper extremities traumas or pathologies. The data was analysed using Microsoft Excel 2013 and SPSS version 23.0 edition. Correlation analysis was done to determine the correlation of the percutaneous humeral length with height, linear regression and binary logistic analyses were used to derive equations for predicting height and sex from percutaneous humeral length. An independent samples t-test was used to determine the means between males and females, left and right percutaneous humeral lengths. Results: There was a strong positive correlation between standing height and left (r = 0.774) and right (r=0.759) humeral lengths. The left humeral length regression equation was a good height estimator in males (75.4%) and females (71.%). The left and right humeral lengths best predicted the sex for the population, with an accuracy of 78.0% and 77.8% for males and 53.8% and 54.6% for females, respectively. Conclusion: This study has added to the limited data on the use of percutaneous humeral length as a substitute for the determination of standing height and sex in the Ghanaian population, and it is also a significant identification tool which can be employed in the field of forensic anthropometry.

    Infertility in Ghana: review and studies of the morphology of the Endometrium
    (1996-07-14) Abaidoo, Chrissie Stansie
    The normal cyclic changes in the endometrium are closely correlated with those in the ovary and fertility is dependent, at least partly, on the ordered sequence of structural changes in the endometrium which occur during the cycle. Infertility is generally defined as the inability of couples of reproductive age to achieve pregnancy despite active attempts to do so for more than a year previous studies have shown that the incidence of infertility is higher in developing countries than in developed ones. However, there is very little published information on the incidence of infertility in Ghana. The aims of this study, therefore, were to review the background of the infertile patients and to examine the endometriuin by serial ultrasonographic measurement of endometrial thickness and histological study of endometrial biopsy. The average thickness of the endometrium was greater in the secretory phase (infertile patients, 6.50 +/- 1.32mm; fertile patients 7.88 +/-1.55mm) than in the early proliferative phase (infertile patients, 2.16 +/- 0.57mm; fertile patients, 2.50 +/- 1.00mm). The texture of the endometrium varied throughout the stages of the cycle studied. The endometrium was more echogenic in the secretory phase arecho-poor in the proliferative phase. Ninety-three per cent of the endometrial biopsies showed secretory activity and about 7% showed proliferative activity. Further analysis of endometrial specimens in the infertile patients by the traditional histological criteria revealed that 81.35% showed normal endometrial development whereas in a 11.86% endometrial development was retarded. These observations suggest that in the group of infertile women studied, anovulation was not the cause of infertility in large majority of the cases. In about 10% of the Study population1 the development of the endometrium appeared retarded Ultrasonography offered an effective noninvasive method for evaluating the thickness of the endometrium.
