The objective of the research was to study the correlation of internal organ weights with body weight and length in normal adult Zambians. The study involved 114 (83 males and 31 females) forensic autopsies from Ndola Teaching Hospital done over a period of 12 months. The cases included autopsies of unnatural deaths including road traffic accidents and homicide. Cases where information about age and origin of the person was not available were left out of the study. The age of the decedents ranged from 16 to 85 years. The data was analyzed by Pearson correlation coefficient to determine correlation. P values less than 0.05 were considered to be statistically significant. It was observed that the heart, liver, left kidney, right kidney, brain, and left lung were positively correlated to body weight, while only the brain and the left lung were positively correlated to the height in the male population. In the female population, the heart, liver, right kidney, brain, and right lung were positively correlated to the weight of the body, while only the right kidney was positively correlated to the height of the body.

The mental foramen (MF) and accessory mental foramen (AMF) are the strategically important landmarks during surgical interventions and anaesthetic nerve blocks procedures involving the mental nerve. The study aimed at evaluating anthropometrics of MF and AMF in Zambian adult human mandibles and it was cleared for ethics from TDRC Ethics Review Committee (Reg. No.: 00002911; FWA: 00003729). A total of 33 Zambian adult human mandibles were evaluated for shape, position, and direction of opening of foramen. All measurements were performed using a Digital Vernier Calliper and statistically analysed for per cent frequency and mean and standard deviations, and we performed the one sample t-test for comparative analysis. Data were considered significant at p<0.05. All mandibles that were examined had bilateral MF while unilateral AMF was found in two mandibles (6%). The foramens were mostly oval in shape and their most common position was between the second premolar and first molar and the most common orientation was posterior-superior. The comparative analysis of mandibular anthropometrics showed significant variations (p<0.05) with different ethnic groups. The findings emphasize the ethnic variations and edify that the foramen position is not always as stated in reference textbooks. The clinical creditability of the study is cautioning the surgeons on possible variations of the MF and AMF anthropometrics compared to existing literature in order to avoid any unforeseen injury related to anaesthesia or dental surgeries. Further studies with large sample sizes representing whole country are recommended to establish the standard MF and AMF anthropometrics of Zambian population.

The objective of the study was to compare the weight of internal organs of the adult Zambian with the values indicated in ICRP 89. The study involved 115 (83 males and 32 female) forensic autopsies from Ndola Teaching Hospital done over a period of 12 months. In this study, subjects who died due to disease process were not included, only accidental and homicide cases were included in the study. The average weight of the internal organs was compared to ICRP 89 values. One sample t-test was used to determine the significance of the differences in weights. P-values less than 0.05 were considered to be statistically significant. It was observed that the weight of the heart, liver, lungs, kidneys and brain were smaller compared to ICRP 89 values, except the size of the spleen which was statistically the same in the male subjects, while the heart and the spleen was statistically the same in the female subjects. The differences in the weights of internal organs was attributed to the differences in body size between ICRP and NTH subjects.
