Therefore, a cross-sectional study of healthy adult participants was conducted from May 2015 to April 2016. The urinary bladder was sonographically evaluated on a convenient sample of 384 adult participants. The BWT, DWT, and BW of the participants were measured and documented. The BW was estimated based on the surface area, thickness, and bladder muscle specific gravity. The mean BWT, DWT, and BW were 2.8 ± 0.3 mm, 1.3 ± 0.1 mm, and 23.3 ± 4.1 g, respectively. There was no statistically significant correlation between anthropometric variables with BWT, DWT, and BW except age, which had a weak positive correlation with BWT ( P = .05). This data set could be used for future research, in other parts of the country, for a possible nationwide nomogram.

Prediction of embryonic implantation prior to IVF has become crucial in counseling patients due to the cost of failed procedure, in terms of huge financial expenditure, time taken for the procedure, associated health risks and psychological effects following unfulfilled expectation. The objective of this study was therefore to develop a scoring protocol and consequently, a predictive model for a successful embryonic implantation in IVF-ET cycles using maternal demographic, endometrial, ovarian, and hormonal parameters as tools for clinical decision and patient counseling. MATERIAL AND METHODS The body mass index (BMI), age, endometrial pattern and thickness, antral follicle count, (AFC) and anti-Mullerian hormone (AMH) concentration of 295 women between the ages of 18-45 years were evaluated prior to IVF- ET at a fertility clinic in Lagos, Nigeria. The AFC, endometrial pattern and thickness were determined sonographically and the AMH assayed, using ELISA test kits. Multiple regression analysis was used to determine the contribution of each parameter to the likelihood of a successful implantation, and a 4 point rating scale was developed based on the relative contribution of each parameter. Scores were then assigned based on the strength of each predictor variable to implantation rates. RESULTS Eighteen women that conceived had a full score of 20, while five that failed to conceive scored below 9. Chi square test indicated that endometrial pattern, thickness, age, AFC and AMH are highly significant in predicting embryonic implantation at IVF, while BMI was insignificant (r = -1.831, p = 0.094). CONCLUSION The prediction model demonstrated a positive correlation between the cumulative score and implantation rate. The use of the scoring system could provide a guide to clinicians to predict the success rate of each IVF-ET procedure prior to commencement of treatment. IMPLICATIONS FOR PRACTICE The availability of this prediction model provides a counselling tool for physicians to IVF clients which ensures improved confidences level and reduced disappointments from failures in successful implantation and embryonic transfer including its associated financial costs and health risks.

Accurate diagnosis of most acromioclavicular (AC) joint pathologies depends on the knowledge of the normal range values of acromioclavicular joint space. The variation in the normal AC joint spaces among the studied population points to the need to have population-specific reference range values of acromioclavicular joint space while the paucity of data on normal acromioclavicular joint space diameter in our locality necessitated this study. Objective: This study was, therefore, aimed at radiographically determining the normal reference range values of acromioclavicular joint space diameter with age in adult Nigerian and also to find its variation with sex. Methods: This retrospective study was conducted in three tertiary hospitals in Enugu from January 2019 to July 2019. It involved digital anteroposterior shoulder radiographs of 628 adults (18 – 80 years) obtained using Zanca’s vie...

The carotid peak systolic velocity (PSV) and end-diastolic velocity (EDV) are key indices for determining the severity of the stenosis. However, normative values of these parameters may be dependent on anthropological variables like age and body mass index (BMI) Objective: The study was aimed at assessing the variations of PSV and EDV with age and BMI in a sampled Nigerian population. Materials and Methods: A total of 204 participants (72 males and 132 non-gravid females) aged between 20 and 70 years who were normotensive with no cardiovascular diseases were selected. Their ages, BMI, PSV and the EDV were measured using standard protocols for the four segments of the carotid artery: common carotid (CC), carotid bulb (CB), internal carotid (IC) and the external carotid (EC). Data obtained were presented using tables and line graphs while the a...

Objective: To develop normal reference values for luminal diameter of the abdominal aorta in Abuja, Nigeria. Materials and Methods: The luminal diameters of the abdominal aorta (AA) of 422 male and female healthy subjects were measured sonographically using standard protocol. The relationship between age, body mass index (BMI), gender and the luminal diameter of the AA were investigated in the subjects. Statistical analysis was performed by the student T-test and Pearson's correlation coefficient at 5% level of significance. Results: The values of the luminal diameter of the AA in the healthy subjects were 15.16 ± 0.55 mm in males and 15.15 ± 0.55 mm in females respectively. The 5 th and 95th percentile normal reference limits of the AA were 14.20 mm and 16.10 mm respectively. There were no significant differences in the luminal diameter measurements in male and female subjects. Age correlated significantly with luminal diameter (r=0.90) of the AA in both gender. BMI showed weak significant correlation with luminal diameter (r=0.136) of the AA in female healthy subjects only. Conclusion: The normal reference values for luminal diameters of the abdominal aorta for male and female healthy subjects have been established in this study. Age is the only significant independent predictor of the luminal diameter of the AA.

Objectives: This study was aimed at establishing that mobile phones are sources of nosocomial infections in the radiology department of our teaching hospital and also to determine the pathogens that are responsible for these infections. Methods: This was a prospective study that involved collection of swab samples from radiographers’ mobile phones. Three different samples were collected from each mobile phone. Thirty (30) mobile phones were used for this investigation and ninety (90) samples were totally collected. Samples were collected on arrival of the radiographer to the department, after handling patients and after washing hands. Samples collected were sent to the microbiology department for culture analysis. Descriptive data analysis was performed and results presented in frequency ta...

Early fetal anomaly screening is usually done using nuchal translucency scan and other invasive procedures such Chorionic villus sampling and amniocentesis. Increase in Nuchal translucency thickness (NTT) above a certain baseline values has been found to predict fetus with anomaly. Baseline values in use are generated from Caucasian population even though these values are known to be population specific. Hence, their use on any given population may lead to errors and introduce potential misdiagnosis. Therefore, there is need for population specific baseline values of NTT.Objectives: The study is aimed at developing baseline values of NTT among apparently normal fetuses from pregnant women of Igbo ethnic group and to assess the relationship of NTT with maternal age and fetal g...

The foundation of osteoporotic fractures stems from childhood. Therefore, studies that promote maximising peak bone mass are strongly advocated. Studies have shown that there are differences in the incidence of osteoporotic fractures in rural and urban communities. No study has investigated urban-rural differences in BMD of Nigerian children. This study, therefore, aimed to investigate urban-rural differences in BMD of Nigerian children and the association with physical activity, demographic and anthropometric variables. METHODS In a cross-sectional, study in Enugu, Nigeria, estimated bone mineral density (eBMD) was measured at the calcaneum using the QUS densitometer, Hologic Sahara, in 457 urban (Enugu metropolis) and 559 rural (Nsukka community) children aged 6-14 years. Height, weight and physical activity were measured. Independent sample t-test was used for comparative analysis while Pear...
