Background: Acute appendicitis is currently considered one of the most common acute surgical diseases of the abdomen and requires emergency surgery. It is also one of the most common abdominal emergencies in both developed and developing countries. The current study is aimed at assessing the specificity and sensitivity of Ultrasound and Computed Tomography in the diagnosis of appendicitis as well as the prevalence of its complications. The association of appendicitis with several laboratory findings will also be evaluated.

Methodology: A retrospective study was conducted at Dallah-Namar Hospital, Riyadh City, Saudi Arabia.

Results: 720 patients were differentially diagnosed with appendicitis in the study area. Of these, 618 patients had US abdomen/pelvis, with 15 (2.4%) showing positive findings. Amongst the 203 patients noted to have undergone abdominal CT,8 (4.0%) was found to have positive findings.

Conclusion: The sensitivity of the US was determined to be relatively low. Also, serum creatinine was found to be elevated among all patients diagnosed with appendicitis. Further research with a larger sample size is needed to be conducted to further support the current findings.

Systemic Lupus erythematosus (SLE) is an autoimmune disorder characterized by the proliferation of autoantibodies and immune dysregulation resulting in damage to many body organs. Pediatric SLE usually presents with fever, joint pain, rashes, and lupus nephritis. It is uncommon to have large pericardial effusions in children with SLE and cardiac tamponade as the initial presentation of SLE is even rarer. An 11-year-old female presented to our Children Emergency Unit with fever and fast breathing for two weeks, bilateral leg swelling of four days, and cough of two days duration. She was acutely ill, tachypneic, and dyspneic with marked orthopnea, bilateral leg edema, and raised JVP. She was tachycardic with a diffuse apex beat. Chest X-ray showed a large globular heart. 2D-Echocardiography showed a large circumferential pericardial effusion with a dilated non-collapsing IVC and diastolic collapse of the right ventricle. She had a pericardiotomy done and 650mls of serous pericardial fluid was drained. The inner pericardium had a fibrinoid exudate with a "bread-and-butter" appearance. Pericardial fluid cytology showed no malignant cells while pericardial biopsy showed suppurative granulomatous inflammation. Antinuclear antibody (ANA) was strongly positive. The patient was managed with corticosteroids, colchicine, and hydroxychloroquine, and has remained stable on follow-up. While cardiac tamponade as an initial presenting complaint in SLE is rare, it is important that children presenting with large pericardial effusions and tamponade be evaluated for rheumatologic disorders. This can be crucial to revealing the correct diagnosis and instituting appropriate care.

Background: Bladder spasms due to involuntary contraction of the bladder occur frequently following Transurethral resection of the prostate (TURP). They may be aggravated by the presence of a catheter, blood clots, preoperative overactive bladder, or preoperative ingestion of bladder stimulants like caffeine. These bladder spams are painful, associated with peri-catheter leakage of urine, increased post-operative bleeding, and often refractory to postoperative analgesia. The incidence and risk factors for the occurrence of bladder spasms following TURP need to be reviewed and validated to ensure adequate patient counseling and possible lifestyle modification before surgery. We conducted a prospective review of the determinants of bladder spasms in our patients following TURP.

Methodology: The study population was patients with benign prostatic obstruction scheduled for TURP between March 2022 and April 2023. Monopolar transurethral resection of the prostate was done using a continuous flow resectoscope. The primary endpoint of the study was occurrences of bladder spasms postoperatively before the trial without a catheter. Pain perception during the spasms was assessed using a visual analog scale. Clinical data were collected and analyzed to determine their association with the occurrence of bladder spasms postoperatively using regression analysis. Sub-group analysis was also done to correlate significant variables with the severity of pain in patients with spasms.

Results: The mean age of the 80 patients reviewed was 66.9 ±8 years. Bladder spasms were seen in 41(51.2%) of the patients. The presence of overactive bladder (OAB) symptoms and the use of bladder stimulants were statistically significant determinants with a p-value of 0.003 and 0.026 respectively. The age of the patient, preoperative indwelling catheter, prostate volume, and resection time were not statistically determinant variables in the occurrence of bladder spasms post-operatively. 61% had severe pains and 39% had mild pains. There was no significant correlation between the presence of OAB or the use of bladder stimulants with the severity of pains in patients with bladder spasms after TURP.

Conclusions: Half of the patients are likely to have bladder spasms after TURP. The risk of having these spasms is higher in patients with preoperative OAB or patients who are exposed to bladder stimulants. The severity of spasms is however independent of these risk factors.

Background: Tax relief and incentives are utilized to encourage the private health sector to provide services that are advantageous to community health. The aim of this study was to explore the issues related to taxes paid, incentives provided, returns on investment, satisfaction with practice, and plans of private health practitioners who were conference attendees in Port Harcourt in 2021.

Methodology: A descriptive cross-sectional study was carried out at two national events in Port Harcourt, Rivers State, Nigeria in October, and December 2021, among conference attendees using self-administered questionnaires. Data obtained was analyzed using the IBM Statistical Package for the Social Sciences (SPSS) version 20.0 and presented in tables.

Results: A total of one hundred and sixty-six (166) respondents were involved in the study. One hundred and four (62.7%) respondents believed they experienced multiple taxation from agencies of government. Most respondents paid at least fifty thousand and above as taxes to various levels of government. One hundred and forty-two (85.5%) respondents believed they did not receive any incentive from governments for their private health businesses. Fifty-three (31.9%) were not satisfied, while55 (33.1%) respondents were managing to survive in the business environment.

Conclusion: Private healthcare practitioners in Nigeria experience multiple taxation and a lack of incentives from governments. Dissatisfaction with the return on investment is prevalent. Inclusive health sector reform that will partly reduce the potential for brain drain is therefore needed.

Background: The activities of Health maintenance organizations (HMO) are central to the achievement of universal health coverage. This study sought to examine the number of HMOs actively operating in the FCT and to determine whether the HMOs are promoting or inhibiting universal coverage and proffer recommendations for the overall progress of the scheme.

Methodology: A descriptive prospective cross-sectional study design was used and mixed (qualitative and quantitative) methods A pre-tested interviewer-administered questionnaire make was used to collect quantitative data while qualitative data were collected through a review of literature and in-depth interviews to examine the roles of HMOs from stakeholders' points of view. A total of 250 participants comprised predominantly 230 enrollees into three major programs of the NHIS that is the formal sector social insurance program (FS-SHIP), tertiary institution social health insurance program (TI-SHIP), and community-based social health insurance program (CB-SHIP). The remaining 20 (twenty) enrollees comprised NHIA desk officers, HMO managers, community-based representatives, and healthcare providers.

Results: The majority of the respondents (64.8%) reported a high level of awareness of the knowledge of NHIS, while fewer than 19% indicated a lack of awareness as compared to 17% who did not respond to the question. Similarly, most of the respondents (62.2%) reported having satisfactory knowledge of the structure-function modalities of HMOs, while 20.4% were not aware of the mode of operation of HMOs.Contrasting contributions of HMOs to NHIS implementation, approximately half of the respondents (50%) reported dissatisfaction. Likewise, about 50% of the study subjects were of the view that HMOs are not putting the desired commitment towards achieving this goal of universal health coverage. The report from the in-depth interview reiterated that the enrollees were not well satisfied due to the perceived poor and inadequate operational mechanisms of both the HMOs and NHIS.

Conclusions: The study revealed a high level of awareness of the knowledge of NHIS and good working knowledge of the structure and function of the HMOs. However, this study demonstrated a low understanding of the working interactions between the NHIS and HMO, among the respondents. Understanding HMOs and how they work is critical for choosing a health plan during open enrollment, hence, there is a need for more client enlightenment.

Background: Considering the high cost of Magnetic Resonance Imaging and the high risk of radiation exposure to growing children from Computed tomography scans, we aim to evaluate the neuroimaging findings in children with chronic headaches, determine the frequency of significant remediable pathologies, and establish the need for neuroimaging.

Methodology: This is a cross-sectional study of clinical data and neuroimaging findings in 41 children who were imaged in a tertiary hospital and a private diagnostic center in Abuja on account of chronic headaches. Twenty-two children were referred for brain Computed Tomography scan while 19 had brain Magnetic resonance Imaging. Collected data was statistically analyzed using SAS software version 9.3 with the level of significance set at 0.05.

Results: The age range of patients was 4 -18years.Thirty-three patients (80.5%) had chronic primary headaches while eight (19.5%) patients had additional "red flag" indications. Normal findings and extracranial lesions accounted for 89.5% of MRI (17/19) and 72.7% (16/22) in CT. Intracranial lesions were seen in 75% of patients with "red flag" and 6.1% of patients with primary headache with significant differences (p=0.0001) between the subsets. The commonest abnormalities were chronic sinusitis (17.1%) and intracranial tumors (9.6%) with no significant difference in the overall neuroimaging findings across the age groups. Chronic sinusitis was found predominantly in adolescent females (85.7%).

Conclusions: Neuroimaging has a low yield of significant remediable intracranial lesions in children with chronic headaches without additional "red flag" symptoms thereby necessitating the call to reconsider the use of neuroimaging with a view to imaging gently.

Background: Obesity is a preventable public health problem associated with a significantly increased risk of non-communicable diseases. This study aimed to find the socio-demographic and nutritional factors associated with obesity amongst adults from high-burden kidney disease areas of Jigawa State, Nigeria.

Methodology: A cross-sectional survey was conducted to assess the socio-demographic and nutritional factors associated with obesity among 361 adults from four local government areas (LGAs) of Jigawa state identified to have a high burden of kidney diseases. The Modified WHO STEPS questionnaire and multi-stage sampling technique were employed, and data were analyzed using IBM SPSS version 22.0.

Results: The minimum age of the respondents was 18, and the maximum was 102 with a median of 45 (interquartile range = 30-80) years. The prevalence of obesity and overweight in the high-burden LGAs of Jigawa state was 33.0% and 27.1% respectively. Hadejia LGA had the highest (68.1%) prevalence of obesity. The prevalence of overweight was higher in Jahun LGA (38.9%). About one-third (38.2%) had a waist circumference (WC) greater than 88cm. Up to half of the female respondents had a waist-hip ratio (WHR) greater than 0.85. For male respondents, many (74.3%) had a WHR of greater than 0.9, and obesity was significantly higher (39.8%, P s< 0.001) among those ≥40 years of age. Obesity was significantly higher (39.8%,P < 0.001) among those ≥40 years of age, known diabetic, (57.1%, P=0.02), and rare consumption of vegetables, (45.8%, P<0.001).The odds of developing obesity were significantly higher among those who were known diabetics and were 3 times more likely to be obese than those who were not known to be diabetics (adjusted odds ratio [aOR] = 3.1, 95% CI = [1.1-8.9].

Conclusions: The prevalence of obesity was high in the areas with high burdens of kidney disease. The government and relevant stakeholders should develop a cost-effective prevention, early diagnosis, and treatment model.

Background: Tuberculosis (TB) and the Human Immune Deficiency Virus (HIV) represent major public health challenges and are intricately linked to each other. This is more prevalent in the sub-Saharan African region, where about 80% of this co-infection is recorded. This study aimed to review the prevalence, profile, and treatment outcome of TB-HIV co-infected patients.

Methodology: A hospital-based retrospective study was conducted in a tertiary center in southeast Nigeria for the period 2015-2017. Information elicited from participant's medical records included socio-demographic profile (age, sex, residential area, and occupation), Cluster of Differentiation 4 (CD4) count level at the time of diagnosis of co-infection, weight, treatment outcome, as well as the record of the number of TB patients who presented within this same period.

Results: The total number of TB/HIV co-infected patients who participated in the study during this period was 207, with a prevalence of TB/HIV co-infection of 33.9%. The highest proportion of cases was recorded among participants within the age group of 31-40, and the cases of co-infection were more common in males (58.9%) and students (27.5%). The results also showed a significant relationship between gender, occupation, residential area, and TB/HIV co-infection. Most of the co-infected participants had a CD4 count of <300 cells/mm3 and an associated poor treatment outcome of 41.1%.

Conclusions: TB/HIV co-infection needs to be properly addressed, and screening for HIV among TB patients should be a priority. This will help in early diagnosis and subsequently improve the treatment outcome of both diseases.

Background: The Maslach Burnout Inventory (MBI) is the most widely accepted tool for assessing burnout among students worldwide. However, no studies have yet tested the validity of the student version of the MBI in Nigeria. The study aimed to assess the factorial structure and cross-cultural validity of the Maslach Burnout Inventory-Student Version MBI-GS (S) in a Nigerian university.

Methodology: An online cross-sectional study was conducted among 536 undergraduate students from three departments in the Faculty of Basic Medical Science at a Nigerian university. Data were collected using MBI-GS (S) and a confirmatory factor analysis was performed to explore its factor structure.

Results: The results revealed that the three-factor, 15-item structure of the MBI-GS (S) demonstrated a valid factorial structure among Nigerian undergraduate students, evidenced by the extraction of three components with eigen values exceeding 1, accounting for 73.7% of the variance, in line with the three-factor structure of the original MBI. The internal consistency of the questionnaire was high, with a Cronbach's alpha value of 0.901. The Cronbach's alpha for emotional exhaustion, cynicism, and academic efficacy were 0.901, 0.841, and 0.941, respectively. A weak negative correlation was observed between emotional exhaustion and cynicism, and a moderate negative correlation was found between emotional exhaustion and academic efficacy, and cynicism and academic efficacy.

Conclusions: These findings suggest that the MBI-GS (S) is a reliable tool for assessing burnout levels among Nigerian university students. They provide strong evidence for the factorial validity and reliability of the MBI-GS (S), supporting its cross-cultural validation for assessing burnout.

A new Mental Health law was recently enacted in Nigeria to replace the Lunacy Ordinance of 1958. The passage of the new law was a major leap from the old. It was received with excitement because the former law was not only outdated but failed to address core issues such as the promotion of mental health and the protection of the rights of the mentally ill. Though the new law adequately makes provisions for these, it has considerable flaws that may hinder implementation. Parts of it lack clarity and other parts are somewhat overzealous in safeguarding the mentally ill, thus potentially defeating its purpose. It appears that certain aspects were not well thought out, or there was no 'looking well' before leaping to legislate. This paper aims to critically review flawed aspects of the new law and make recommendations on the way forward.
