    Gross morphometry of the human placenta and umbilical cord with reference to neonatal indices
    (MARCH, 2015) Tetteh, Joshua
    In recent years more attention has been focused on the morphology of the placenta and umbilical cord due to their vital roles in foetal development and neonatal survival. While extensive studies have been documented in this area in the developed world, there is very little published information about the morphological variations that occur in human placenta and umbilical cord in Ghana. Therefore this study was designed to evaluate the structural variations in placental indices, umbilical cord indices and neonatal outcome and also compare the data obtained with other samples for regional variation. A total of 236 placentae with attached umbilical cords were obtained from the Kwame Nkrumah University of Science and Technology Hospital in Kumasi between February and July 2013 for this study. Mean placental indices for weight, diameter and thickness were 578.81 g, 17.40 cm and 2.04 cm respectively. The mean neonatal indices were 3.24 kg, 34.27 cm and 50.64 cm for weight, head circumference and length respectively. Neonatal weight correlated significantly with placental weight, neonatal length and neonatal head circumference (P < 0.05). On the contrary, neonatal weight had no significant correlation with placental thickness and diameter. However, there was significant correlation between the umbilical cord length with umbilical cord diameter, umbilical cord artery A1 diameter, umbilical cord artery A2 diameter and volume of Wharton’s jelly (P < 0.001). Based on the results of the present study, the placental weight, umbilical cord length and diameter and neonatal weight values compared with other sampled populations showed significantly lower values. These findings suggest that regional variations exist with these parameters which are likely to contribute to the high neonatal morbidity and mortality rate reported in Ghana. This study further affirms that the placenta and umbilical cord should be critically examined in order to effectively monitor and manage adverse neonatal outcome.

    Height and sex estimation using percutaneous humeral length among Ghanaians
    (Elsevier, 2024) Tetteh, Joshua; Diby, Thomas; Abaidoo, Chrissie Stansie; Yorke, Joseph; Robertson, Juliet; Nketsiah, James; 0000-0002-5229-0340
    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 percu taneous 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.
