Research in forensic anthropology is recent in Malaysia due to limited access to documented skeletal collections. However, advanced imaging techniques provide virtual bone samples for use in morphometric studies to establish population-specific standards by virtual anthropology. This study examined sexual dimorphism in the subpubic angle using a three-dimensional computed tomography model of the pelvis, in a contemporary Malaysian population. The sample comprised multidetector computed tomography (MDCT) scans of 50 male and 50 female adults. Segmentation of the MDCT scans was performed using 3D Slicer, and four landmarks were acquired using Stratovan Checkpoint for the subpubic angle measurement. The technical error of measurement (TEM), relative TEM, and coefficient of reliability (R) exhibited high reliability in measurements. Results showed that the subpubic angle in males was 68.6°±7.6° and in females 87.4°±6.5°. The subpubic angle in females was significantly larger than in males (P<0.001). Inverse correlation was found between the subpubic angle and age, in both males (r=–0.449, P<0.01) and females (r=–0.385, P<0.01). The overall accuracy of sex estimation using the subpubic angle was 94% (P<0.001). The subpubic angle, with a demarcating point of 78.6°, showed a sensitivity and specificity of 94% in the classification of female individuals. In conclusion, sex estimation using the subpu bic angle is highly accurate, with a high degree of expected sensitivity and specificity in the Malaysian population.

Introduction: A person’s childhood is an important period of
growth, and also one’s most vulnerable, as one can be
exposed to various pathologies, for example those that
could affect the growth of one’s kidney. Asians are
physiologically different from Caucasians, and the
nomogram renal size obtained from a Western population
(mostly of Caucasians) is not be suitable for representing
Asian children. As such a nomogram on paediatric renal size
derived from Malaysia is needed.
Methods: A total of 109 (64 males and 45 females) aged 0-12
in Pusat Perubatan Universiti Kebangsaan Malaysia
(PPUKM) took part in this study. They underwent
ultrasonography of both kidneys, and their demographic
and anthropometric data were collected. The mean and
standard deviations of the renal length and renal volume
according to their age groups was calculated, and the final
data was compared to the ones reported by Rosenbaum et
al. (1984).
Result: Body weight and Body Surface Area (BSA) of the
children reported the strongest correlation with renal size.
Significant differences were found between local and the
data from Rosenbaum et al (1984). A nomogram on
paediatric renal size based on children in PPUKM was then
created.
Discussion: Ultrasonography is regarded as the standard
method for determining renal size. Body weight and BSA
were both strongly correlated with renal size. It was shown
that the widely used nomograms derived from data obtained
from Caucasian was not suitable to represent the population
of Malaysian children.

Herein is a case report of a 70 years old man with a tenacious benign prostatic hyperplasia (BPH). The aim of this manuscript is to briefly discuss the usage and advantage of EmbozeneTM Microsphere in embolization of the prostate arteries in the treatment of failed medical and surgical therapy for BPH.
