Background: The world is remodeling with the emergence of the most revolutionary technological advancement called artificial intelligence (AI). The study is to evaluate the knowledge, practice, and perception of AI in healthcare among care providers. Methodology: A descriptive, prospective design was adopted over a period of 8 months using a well-structured, self-administered questionnaire administered to medical practitioners. A total of 510 questionnaires out of 525 administered were retrieved immediately after completion. The responses were collated and analyzed using SPSS version 21.0 in line with the study objectives. The data were presented orderly in frequency tables and charts. Results: Male constituted 59.02%, while the female was 40.98%. The mean (±standard deviation) age of the respondents is 45.88 ± 10.26 years. 21.18% of the respondents are consultants, 42.35% are resident doctors while 9.22% are medical officers and 27.25% constituting interns. 94.31% of the respondents know about AI, and the internet has been the main source (89.32%). Majorities know that AI is applied in radiology (96.50%) and surgery (94.05%). Four hundred and thirty-seven (91.81%) responded that there was no form of AI in their facilities and are willing to be trained. Two hundred and sixty-eight (55.83%) agreed that AI would improve healthcare services, while 43.66% of the respondents thought that it will eliminate the human factor. Poor knowledge of information technology, absence of legislation, and promotion of self-medication were the anticipated challenges. Conclusion: Little is known about AI use in pathology, drug-dispensing, and nursing care. There is no AI practice in this environment, but physicians are willing to embrace AI. The fear of eliminating the human factor and cause job loss remained a concern. Training and legislation to regulate AI use are recommended to improve the knowledge, practice, and perception of AI among medical personnel in the developing world.

Background: Despite the current availability of highly active antiretroviral therapy (HAART) in our hospital, neurologic complications of HIV still occur. Aim: The aim of this study was to document brain computed tomography (CT) findings in HIV patients receiving HAART who developed neurological complications and to examine the relationship of these findings with CD4 cell counts. Materials and Methods: Twenty patients with central nervous system symptoms out of 200 HIV/AIDS patients receiving HAART at the HIV Clinic of Federal Teaching Hospital, Gombe, were retrospectively studied. The findings were reviewed alongside their clinical features, CD4+ count, and HAART history. Results: CT findings were positive in 12 (60%) of the patients, while no abnormality was seen in 8 (40%) of the patients. The most common brain abnormality was atrophy (35%). Two out of 5 patients (40%) with CD4 counts >200 had abnormal CT findings compared with 9 out of 14 patients (64%) with CD4 counts

Background: The gall bladder is one of the abdominal organs that are frequently affected in sickle cell disease. This results from chronic hemolysis with its accelerated bilirubin turnover, which leads to a high incidence of gall bladder diseases. Ultrasonography is a cost-effective and noninvasive modality that permits a quick evaluation of the gall bladder in patients with sickle cell anemia. Objectives: The aim of this study was to evaluate changes in gall bladder in children with sickle cell anemia using ultrasonography. Materials and Methods: This prospective study was conducted in the department of radiology, Aminu Kano Teaching Hospital, Kano (AKTH). One hundred children with sickle cell anemia and age and sex-cross-matched 100 healthy controls aged 15 years and below were recruited for this study, (in accordance with what is obtainable at AKTH, Kano). The examination was performed using an ultrasound machine equipped with a 3.5 MHz curvilinear ultrasound transducer. The gall bladder changes that were assessed include cholelithiasis, cholecystitis, biliary sludge, and volume. Results: From the 100 children scanned, there were 68 (68%) males and 32 (32%) females in each of the study groups, with an age range of 2–15 years. The mean age of the cases and controls was 9.63 ± 3.79 years and 8.49 ± 3.39 years, respectively (P = 0.024). Among the patients; 19 (19%) had cholecystitis, 9 (9%) had gallstones and 8 (8%) had biliary sludge, with no detectable abnormality in the controls. Conclusion: The ultrasonographic prevalence of gallbladder abnormality is higher in patients with sickle cell anemia when compared to normal healthy controls showing increased prevalence with age.

Background: Uterine leiomyoma represents a major public health problem and is regarded as the most common benign gynecologic tumors affecting premenopausal women. It is associated with considerable morbidity and hospitalization. Objectives: This research was carried out to establish the prevalence and sonographic characteristics of uterine leiomyoma as well as the histological diagnosis of the tumour among Nigerian women of reproductive age living in Jos Plateau State. Methodology: This is a prospective cross-sectional hospital based study in which 295 women of the age between 20 years to 50 years was recruited randomly after obtaining an informed consent from each. Abdomino-pelvic ultrasound scan was performed on each participant using a GE Logic 5 machine fitted with 3.5MHz probe with emphasis on the location, number and characterization of uterine leiomyoma(s); thereafter trans-vaginal ultrasound scan using 7.5MHz frequency probe, was done for the subjects that have uterine fibroid for better delineation and location of the mass(es), followed by Sonohysterography where necessary to ascertain its/their location(s). The histologic findings/diagnosis of the tumour post surgery for those who had myomectomy in course of the study was correlated to the sonographic diagnosis. The number of fibroid nodules, location in the uterus, sonographic patterns, classification and histological diagnosis were assessed descriptively and inferentially using the Statistical Package for Social Scientists version 20 (SPSS20). The results were presented in form of tables and charts. RESULTS: The mean age for the participants was 32.66+7.66 years ranging from 21 to 50 years. The mean age of the sonographically confirmed fibroid cases was 34.99+6.79 years with a range of 21 to 48 years.The study indicated that 28.33% (83/295) of the subjects had fibroid; the highest prevalence (49.7%) of the fibroid case occurred among women in their fourth decade and the lowest (8.4%) at the extremes of reproductive age. A significant positive association (P=0.043) between nulliparity and the presence of fibroid was noted. The average number of fibroid nodules and volume of the largest nodule were estimated as, 2.76+1.93 and 344+69.24cm3respectively; 57.80% of the fibroid were intramural with only 9.6% been submucosal. Most (86.70%) of the fibroids were located within the uterine corpus and the most common (38.6%) sonographic pattern of the nodules was hypoechoic. The histological findings post myomectomy for those that had surgery in the course of the study showed no evidence of malignant transformation. Conclusion: The prevalence and sonographic pattern of leiomyoma among women of reproductive age in Jos have been assessed; it was found that characteristics of the fibroid and its location determine the clinical presentation and possibly the reproductive outcome of the patient; this could help in appropriate management of cases in the North-Central or the whole nation.

Background: Brain tumors are among the most challenging disorders encountered worldwide. Early and accurate diagnosis is essential for the management of these tumors. Different patterns of distribution of intracranial tumors have been described in various regions of the world, with previous reports in Africa suggesting that brain tumors were uncommon. This relative rarity has been attributed to low detection due to lack of neurosurgical and advanced neuroimaging facilities previously, a limitation that has now been gradually surmounted with the establishment of neurosurgical and more advanced radiological facilities on the continent. Objectives: The objective of this study is to describe the current pattern of intracranial tumors on computed tomography (CT) scan seen in Ahmadu Bello University Teaching Hospital (ABUTH) Zaria, Northwest Nigeria. Methods: This is a retrospective study of CT images of 60 patients of all age groups diagnosed with brain tumors between January 2015 and December 2019. The CT scans of the brain were performed using General Electric Hi-Speed NX/i dual-slice CT scanner (Germany). The age, sex, diagnosis using the WHO histological, and the pattern on CT were recorded, and data were analyzed using Statistical Package for the Social Sciences version 22.0, ARMONK, NY, USA 2013. Only cases with conclusive histology diagnosis were analyzed. This study was approved by the Health Research Ethics Committee of the ABUTH, Zaria (approval Number ABUTH/HREC/M36/2015), on January 23, 2015, before commencement. Results: In the 60 cases of brain tumors studied, patients' age range was 6 months–65 years, with a peak in the fourth and fifth decades of life (accounting for 38.3%). The mean age was 33.04 years ± 17.73 standard deviation. There was equal occurrence among males and females. About 96.7% of the tumors were primary and 3.7% secondary tumors; meningioma (MEN) (45%) was the most common tumor seen. About 45% of the cases were extra-axial, while 55% were intra-axial. Most (81.67%) of the tumors were located in the supratentorial region, while 18.33% were infratentorial. Headache (75%) and visual impairment (53.3%) were the most frequent clinical presentations. Conclusion: MEN was the most common tumor type seen in this study. This corroborates most studies in Nigeria and other African countries but contradicts some studies among Caucasians that showed glioma to be more common. This affirms that racial factors and environmental influence could have significant effects on the pattern of diseases. The results of this study will provide useful data on the pattern of brain tumors in this environment.
背景:脑肿瘤是世界范围内最具挑战性的疾病之一。早期和准确的诊断对于这些肿瘤的治疗至关重要。颅内肿瘤在世界不同地区的分布模式不同，以前在非洲的报告表明脑肿瘤并不常见。这种相对罕见的情况是由于以前缺乏神经外科和先进的神经影像学设施而导致的低检出率，现在随着神经外科和更先进的放射学设施的建立，这一限制已逐渐被克服。目的:本研究的目的是描述尼日利亚西北部扎里亚Ahmadu Bello大学教学医院(ABUTH)颅内肿瘤的计算机断层扫描(CT)的当前模式。方法:回顾性分析2015年1月至2019年12月诊断为脑肿瘤的各年龄组60例患者的CT图像。颅脑CT扫描采用德国通用电气高速NX/i双排CT扫描仪。记录患者的年龄、性别、WHO组织学诊断和CT表现，并使用Statistical Package for The Social Sciences version 22.0, ARMONK, NY, USA 2013对数据进行分析。仅分析组织学诊断为结论性的病例。本研究于2015年1月23日获得Zaria ABUTH卫生研究伦理委员会批准(批准号ABUTH/HREC/M36/2015)，开始研究。结果:60例脑肿瘤患者年龄范围为6个月~ 65岁，以40岁、50岁居多(占38.3%)。平均年龄为33.04岁±17.73标准差。在男性和女性中发病率相等。原发肿瘤占96.7%，继发肿瘤占3.7%;脑膜瘤(MEN)(45%)是最常见的肿瘤。约45%的病例为轴外，55%为轴内。81.67%的肿瘤位于幕上区，18.33%的肿瘤位于幕下区。头痛(75%)和视力障碍(53.3%)是最常见的临床表现。结论:MEN是本研究中最常见的肿瘤类型。这证实了尼日利亚和其他非洲国家的大多数研究，但与一些在白种人中显示神经胶质瘤更常见的研究相矛盾。这证实，种族因素和环境影响可能对疾病的模式产生重大影响。这项研究的结果将为这种环境下脑肿瘤的模式提供有用的数据。
