Clinical Profile of Patients on Highly Active Antiretroviral Therapy (HAART) Seen in a Tertiary Eye Clinic.

Background: Highly active antiretroviral therapy (HAART) is the medication regimen for the management of human immunodeficiency virus. Over time, it has been dubbed to have revolutionised the clinical course and outcomes of HIV/AIDS. Objective: The objective of this study is to determine the clinical factors associated with the ocular manifestation of HIV/AIDS among patients on HAART. Materials and Methods: This was a descriptive cross-sectional study conducted at the ophthalmology department of the University of Nigeria Teaching Hospital (UNTH) in 2017 among adult patients (≥18 years) attending the hospital's antiretroviral therapy (ART) clinic and selected using systematic random sampling technique. Statistical Package for Social Sciences (SPSS) version 21 was used for data analysis, with variables being summarised using frequencies and proportions. Inferential statistics (t test, Chi-square test, and Fisher's exact test) was used to test associations between variables. A level of significance was set at a P value of less than 0.05 corresponding to a 95% confidence interval. Results: A majority of patients were in WHO stages 1 and 2 of HIV and the mean CD4+ cell count of the whole population was 575.0 ± 512.56 cells/µL, while that of those with ocular manifestations was 315.2 ± 290.76 and 633.7 ± 533.54 cells/µL for those who do not have ocular manifestation. There was a significant association between CD4+ cell count and ocular manifestations such as conjunctival microvasculopathy, anterior uveitis, and cytomegalovirus retinitis. Conclusion: Our results suggest that HAART has some positive effect on the clinical profile of people with HIV/AIDS with CD4+ count being a major determinant of ocular manifestations.

Prevalence and Causes of Blindness and Visual Impairment Among Nigerian Children: A Systematic Review.

Background: Low/middle-income countries have the highest burden of blindeness and visual impairment, which directly affects the children and indirectly affects their community. Furthermore, the number of blind years suffered by children with low vision or blindness creates a self-perpetuating ripple effect on their development, health and the socio-economic development of their communities. This systematic review aims to interrogate the existing evidence on the prevalence and causes of blindness and visual impairment in Nigerian children to provide evidence to drive health policy. Methods: This was a systematic review without meta-analysis (SwiM) using a narrative synthesis of the evidence reported using the PRISMA guidelines. All primary cross-sectional studies (in English) reporting the prevalence and causes of visual impairment among Nigerian children under 20 years old between 2003 and 2022 were included in this review. PUBMED, AJOL, BASE and ProQuest databases were searched for eligible studies between 6 June and 15 July 2023. The quality of the included studies was assessed using the AXIS tool. Results were extracted and summarised using descriptive statistics. Visual impairment and blindness using the presenting visual acuity in the better eye were reported using the WHO classification. Results: Seventeen studies, involving 16,924 children from 13 states across five geo-political zones in Nigeria, were included in the final analysis of this review. The prevalence of visual impairment was 3.9%, 2.7% and 0.3% for mild, moderate and severe visual impairments, respectively, due to ametropia, cataracts, glaucoma, etc. The prevalence of blindness was 0.2% due to cataracts, corneal scars and optic atrophy. Conclusion: Blindness and visual impairment is still a significant clinical and public health burden among Nigerian children. Hence, there is still a need for clinicians, especially opthalmologists, public health specialists, policy-makers, and other relevant stakeholders to intensify efforts towards the prevention and control of this burden.

Predictive and prognostic relevance of immunohistochemical testing of estrogen and progesterone receptors in breast cancer in South East Nigeria: A review of 417 cases.

ER/PgR testing are now routinely performed in breast cancer evaluation in Southeastern Nigeria. ER is predictive to show beneficiaries of hormonal therapy and a prognostic marker to establish tumors that will resist paclitaxel induced apoptosis so a cost effective combination of anthracylines can be used as treatment in our low resource setting thus improving survival, reducing recurrence, and cost. Four hundred seventeen cases of breast cancer seen over a period of 3 years were routinely tested for ER/PgR. ER positivity was defined as nuclear positivity of 1% in the presence of internal and external controls. Four hundred seventeen patients with Ductal Carcinoma participated. Majority were females 98.3%. Majority 60.2% were between 31 and 50 years old. Mean age was 33.5 ± 6.4 years. Two hundred fifty-seven (61.6%) were positive both for ER/PgR. 70.3% of age group 41-50 years had positive ER, age groups 20-30, and >70 years had positive ER also. ER positive cancer was 60.2%. Fifty-seven were 1%-9% positive. Most positive estrogen receptors were seen between 41 and 50 years at 70.3%. Least was seen at 31-40 years at 51.4%. Study provides an objective basis for using hormonal manipulation and makes cost affordable with appropriate chemotherapeutic agents in our low resource setting. Presentations were typically late. Seventy-six percent of stage 2 disease survived after 6 years compared with only 56% of stage 2 disease prior to immunotyping and radiotherapy in 2007. Both stage 3 and 4 had remarkable survival too at 55% and 33% respectively when compared with 2007 figures at 33% for stage 3 and 9.2% at stage 4.

Comparing Objective Structured Clinical Examinations and Traditional Clinical Examinations in the Summative Evaluation of Final-Year Medical Students.

BACKGROUND: Medical schools have traditionally assessed medical students using long and short cases. Objective structured clinical examination (OSCE) has been found to be more reliable. AIM: To compare OSCE and traditional method of assessment in the summative assessment of final-year medical students. METHODOLOGY: This was a retrospective cross-sectional study conducted at Enugu State University of Science and Technology College of Medicine. The Department of Internal Medicine organized clinical examinations consisting of long and short cases. The Department of Surgery organized an OSCE consisting of two parts (picture OSCE and clinical OSCE). Students' scores in both internal medicine and surgery were collated and subjected to analysis with SPSS version 23 (IBM; SPSS, Chicago, IL, USA). Pearson's correlation was used to assess the correlations, paired t-test was used to compare the mean scores, and Cronbach's alpha was used to assess the reliability. P < 0.05 was considered statistically significant. RESULTS: Out of the 73 candidates, 41 were female and 32 were male giving a female: male ratio of 1.3:1. Using paired sample t test, there were significant differences between the mean score in long case (mean = 52.86, standard deviation [SD] = 4.315) and mean score in clinical OSCE (mean = 58.356, SD = 7.906), t (72) = -7.181, P = 0.000; mean score in short case (mean = 52.86, SD = 4.097) and mean score in picture OSCE (mean = 48.580, SD = 8.992, t (72) =4.558, P = 0.000; no significant difference between the mean total score in internal medicine clinicals (mean = 105.712, SD = 6.680) and mean total score in surgery clinicals (mean = 106.915, SD = 15.846), t (72) = -0.788, P = 0.433. The Cronbach's alpha for traditional examination and OSCE was 0.437 and 0.863, respectively. CONCLUSION: OSCE gives a similar mean score to traditional method, but OSCE is more reliable.

A case of vulval swelling secondary to female circumcision posing a diagnostic dilemma.

INTRODUCTION: The practice of FGM is most prevalent in the African countries such as Nigeria, Ethiopia, Sudan, Egypt, and some area of the Middle East. It is not restricted to any ethnic, religious or socioeconomic class. There are many reasons for perpetuation of this practice; the most common are cultural and religious beliefs. The aim of this paper is to highlight the diagnostic dilemma associated with this type of case and the psychological trauma of a patient following her unfortunate genital mutilations. PRESENTATION OF CASE: We present the case of epidermal inclusion dermoid cyst in an 18-year-old teenage girl referred to us from the gynecologist as a case of hydrocoele of the canal of Nuck involving the left labia majora. Patient was previously seen by general practitioner who diagnosed a left Bartholins cyst. Excision of the mass, revealed a well encapsulated cystic mass containing serous fluid with no extension to the inguinal area, measured 10cm×8cm. Histology showed epidermoid inclusion dermoid cyst probably related to circumcision (female genital mutilation). DISCUSSION: Implantation dermoid cyst though a recognized complication of FGM is rare in our environment and a high index of suspicion is required any time a girl presents with a vulval swelling. Cosmesis still remains the watchword to assuage the psychological impact on the patient. CONCLUSION: There is need for more public health campaigns to educate communities about the harms of circumcision with the goal of eradicating the practice.

Retained intra-abdominal artery forceps - An unusual cause of intestinal strangulation.

CONTEXT: Surgical instruments and materials continue to be retained in the peritoneal cavity despite precautionary measures. Even though uncommon it is also under-reported and carries serious medico-legal consequences. Gauzes and sponges (gossypiboma) are the most commonly retained materials and intra-abdominal retained artery forceps are much rarer but when they do occur lead to chronic abdominal pain and can be a rare cause of intestinal obstruction or strangulation with significant morbidity and mortality. CASE REPORT: We present a case of intraabdominal retained artery forceps in a 70-years-old lady who underwent laparotomy with splenectomy for a large spleen in a peripheral hospital. Upon discharge she continued to complain of intermittent abdominal pain of increasing severity. 12 months later she presented to us with an acute (surgical) abdomen requiring another laparotomy. At laparotomy she had strangulated/gangrenous lower jejunual and upper ileal bowel loops, the small bowel mesentery of this area being tightly trapped between the jaws of the retained artery forceps. She had gut resection and enteroanastomosis. Unfortunately she died from continuing sepsis on the second post-operative day. CONCLUSION: Retained instruments in intra-abdominal surgery can cause serious complication and should be treated surgically. High index of suspicion and appropriate investigations like plain abdominal X-ray, abdominal ultrasound and CT and MRI scans should be instituted in patients who develop chronic abdominal symptoms following laparotomy. Preventive measures against retained instruments must follow strict laid down protocols for surgical instruments handling in theatre.

Impact of education on obesity and blood pressure in developing countries: A study on the Ibos of Nigeria.

BACKGROUND: Increase in the prevalence of hypertension, obesity and obesity related diseases has become significant cause of disability and premature death in both developing and newly developed countries, with over bearing demand on national health budgets. AIM: To evaluate the impact of various levels of education on obesity and blood pressure. MATERIALS AND METHOD: 325 male and 254 female Nigerians of ages 20-80 years of the Ibo ethnicity through random sampling, were selected for this study. The participants were broken into three major groups based on their educational levels; primary, secondary and tertiary levels. systolic and diastolic blood pressure (SBP & DBP) levels, body mass index (BMI), waist hip ratio (WHR), waist height ratio (WHtR), waist circumference (WC),various skin fold thicknesses, and other anthropometric parameters were measured. RESULT: For all the indicators of subcutaneous fat, general obesity, and central obesity, largest mean deposition was noted to be highest in the lowest education group and least in the highest education group. Mean blood pressure parameters were also highest in the least education group. While fat deposition was noted to be highest in all the females of all the groups, the males showed larger mean BP values. Education was noted to have a significant inverse relationship with most of the fat indicators and blood pressure parameters and cardiovascular disease risk highest in the least education groups. CONCLUSION: Education showed a significant impact on obesity and blood pressure and could be one of the major tools to reduce the high prevalence of obesity, hypertension and other obesity associated diseases.
