Histopathological Outcome of Colonoscopic Biopsies in a Tertiary Hospital in Southwestern Nigeria: A 7-Year Retrospective Study.

BACKGROUND AND AIM: Colonoscopy with histopathological analysis of mucosal biopsy samples remains the gold standard procedure for diagnosing lower gastrointestinal disorders. This study aimed to determine the pattern of histopathological findings of mucosal biopsies obtained at colonoscopy over a 7-year period and to correlate the histological findings with the clinical profile of the patients. METHODS: This was a retrospective study conducted in a healthcare facility in southwestern Nigeria. The Histology reports from January 1, 2016, to December 31, 2022, were retrieved from the histopathology department of the institution to obtain the following information for analysis: age, gender, year of the test, presenting complaint, provisional clinical diagnosis, colonoscopy diagnosis, and histological diagnosis. RESULTS: The data of a total number of 81 patients were analyzed; 51 males (63.0%) and 30 females (37.0%) with a male-to-female ratio of 1.7-1. The age range of the patients was 30-86 years with a mean (±standard deviations) age of 59.87 ± 14.44. The most common indication for colonoscopy was hematochezia (23 (28.4%)) followed by change in bowel habit (16 [19.8%]), constipation (11 [13.6%]), and tenesmus (10 [12.3%]). Large bowel masses suggestive of cancers were the most common colonoscopy finding in the study subjects (36 [44.4%]). Colorectal cancer was the most common histologic abnormality in the study subjects (26 [32.1%]) followed by chronic nonspecific colitis (8 [9.9%]), polyps (7 [8.6%]), adenomas (5 [6.2%]) and acute on chronic colitis (5 [6.2%]). Twenty-two (27.2%) patients had normal histologic findings. Patients aged between 45 and 64 years had the highest prevalence of colorectal cancer (13 [50.0%]). CONCLUSION: Colorectal cancer was the most common histopathological finding in this study and the patients were mostly within the middle-age group. Early screening colonoscopy is therefore recommended and histopathological analysis of the mucosal specimens obtained is essential for early detection of premalignant lesions.

Résumé Contexte et Objectif:La coloscopie avec analyse histopathologique d'échantillons de biopsie muqueuse reste la procédure de référence pour diagnostiquer les troubles gastro-intestinaux inférieurs. Cette étude visait à déterminer le schéma des résultats histopathologiques des biopsies muqueuses obtenues à la coloscopie sur une période de sept ans et à corréler les résultats histologiques avec le profil clinique des patients.Méthodes:Il s'agissait d'une étude rétrospective menée dans un établissement de santé du sud-ouest du Nigeria. Les rapports d'histologie du 1er janvier 2016 au 31 décembre 2022 ont été récupérés auprès du service d'histopathologie de l'établissement afin d'obtenir les informations suivantes pour analyse : âge, sexe, année du test, plainte présentée, diagnostic clinique provisoire, diagnostic de coloscopie et diagnostic histologique.Résultats:Les données d'un nombre total de 81 patients ont été analysées; 51 hommes (63,0 %) et 30 femmes (37,0 %) avec un ratio hommes/femmes de 1,7 pour 1. La tranche d'âge des patients était de 30 à 86 ans avec un âge moyen (± ET) de 59,87 ± 14,44. L'indication la plus fréquente de la coloscopie était l'hématochézie (23 (28,4 %)), suivie de la modification du transit intestinal (16 (19,8 %)), de la constipation (11 (13,6 %)) et du ténesme (10 (12,3 %)). Les masses du gros intestin évocatrices de cancers étaient la constatation la plus fréquente de la coloscopie chez les sujets de l'étude (36 (44,4 %)). Le cancer colorectal était l'anomalie histologique la plus fréquente chez les sujets de l'étude (26 (32,1%)) suivi de la colite chronique non spécifique (8 (9,9%)), des polypes (7 (8,6%)), des adénomes (5 (6,2%)) et aigu sur la colite chronique (5 (6,2 %)). Vingt-deux (27,2 %) patients avaient des résultats histologiques normaux. Les patients âgés de 45 à 64 ans avaient la prévalence la plus élevée de cancer colorectal (13 (50,0 %)).Conclusion:Le cancer colorectal était la découverte histopathologique la plus courante dans cette étude et les patients appartenaient principalement au groupe d'âge moyen. Une coloscopie de dépistage précoce est donc recommandée et l'analyse histopathologique des échantillons de muqueuses obtenus est essentielle pour la détection précoce des lésions pré-malignes.

Asymptomatic bacteriuria in patients with type 2 diabetes mellitus in rural southwestern Nigeria: a cross-sectional study.

OBJECTIVES: We aimed to identify the prevalence, bacterial isolates, antimicrobial susceptibility profile, and factors associated with asymptomatic bacteriuria (ASB) in patients with type 2 diabetes mellitus (T2DM) in rural southwestern Nigeria. METHODS: We performed a hospital-based cross-sectional study of patients with T2DM and ASB. Demographic and clinical data were collected using questionnaires. Urine samples were cultured using standard laboratory procedures, and bacterial colonies were isolated and antimicrobial sensitivity was performed using the disc diffusion technique. Relationships between variables were assessed using adjusted odds ratios (AORs) and 95% confidence intervals (CIs). RESULTS: Of the 280 participants, 73 (26.1%) had ASB (95% CI: 20.9%-31.2%). The most commonly identified isolate was E. coli (45/73; 61.7%), 100.0% of which were sensitive to cefuroxime but resistant to ciprofloxacin. Female sex (AOR, 6.132; 95% CI: 2.327-16.157), living below the poverty line (AOR, 2.066; 95% CI: 1.059-4.029), uncontrolled blood glucose (AOR, 2.097; 95% CI: 1.000-4.404), and a history of indwelling urethral catheterization (AOR, 14.521; 95% CI: 4.914-42.908) were associated with ASB. CONCLUSION: The findings suggest that cefuroxime should be used as an empirical treatment, pending urine culture and sensitivity, and that efforts should be made to prevent ASB in rural southwestern Nigeria.

International health regulations and pre-travel health practices of international travelers at Nigerian airport: a cross-sectional study.

BACKGROUND: International Health Regulations (IHR) were developed by the World Health Organization (WHO) to curb the trans-border spread of epidemics. To our knowledge, no airport-based studies have assessed travelers' health practices against a combination of diseases subject to IHR 2005. Therefore, we aimed to generate and describe the baseline travelers' pre-travel health practices towards Cholera, Yellow Fever (YF), and Plague at Murtala Muhammed International Airport (MMIA) in Nigeria. METHODS: A cross-sectional study was employed to collect data from 486 international travelers using a multistage sampling technique. Pre-travel health practices (a combination of pre-travel consultation, pre-travel vaccination, and preventive measures against insect bites) were assessed using an interviewer-administered questionnaire. Logistic regression models were used to estimates the association between selected variables and pre-travel health practices. Statistical significance level was set at 5%. RESULTS: A total of 479 complete questionnaires were analyzed. The median age of respondents was 34.0 years Interquartile range (IQR) = 28.0, 44.0). Of the total respondents, 311 (64.3%) were aware of pre-travel health consultation and sources of information, amongst others, including friends/relatives in 180 (37.6%) travelers, social media/internet in 155 (32.4%) travelers, and health professionals in 102 (21.3%) travelers. Two hundred and seventy-one (56.6%) had pre-travel consultation, 156 (32.6%) had YF vaccination, and 226 (47.2%) were prepared to use preventive measures against insect bites. Only 10.6% had good pre-travel practices against the diseases subject to 2 International Health Regulations (IHR). Travelers with bachelor/college degrees, when compared to those with secondary/high education, had 2.91 times higher odds of having good practices when adjusting for other factors (95% C.I: 1.10, 7.70; p < 0.03). Also, those traveling to destinations endemic for YF infection, when compared to those who are not traveling to endemic countries/areas, had 48% lower odds of having good practices after adjusting for other factors (95% C.I: 1.41, 7.77; p < 0.01). CONCLUSIONS: Our study revealed a low prevalence of good pre-travel health practices among participants. Educational level and endemicity of YF at the destination were predictors of pre-travel health practices. Introducing topics on travelers' health into schools' curriculums may have a ripple positive effect on health practices among international travelers. Also, there is a need for public enlightenment programs on pre-travel health practices using social media platforms.

Abstract Medical students have many different options of academic and professional undertakings after graduation. The aim of this study is to determine the career preferences of students in their final year of medical school and to determine the factors that contributed for such decision. This is a descriptive cross-sectional study involving the final-year medical students of Afe Babalola University, Ekiti State, Nigeria. A well-structured questionnaire was used for data collection. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 21.0. Descriptive statistics included frequency tables, charts, means and standard deviations. A total number of 100 final-year medical students participated in the study, out of which 29 (29.0%) were males and 71 (71.0%) were females, with a male to female ratio of 0.4 to 1. The age range of the respondents was 21 to 30 years, with a mean(±SD) of 23.5(±1.4). 72% of the respondents planned to pursue a postgraduate academic qualification after graduating from medical school, mostly in the United Kingdom, and a Master of Public Health was the most sought qualification. Similarly, 76% of the respondents planned to pursue a postgraduate medical fellowship after medical school, also mostly in the United Kingdom. The specialty most sought-after is Obstetrics and Gynaecology (43%), followed by Surgery (40%), Family Medicine (34%), Community Medicine (33%), Paediatrics (25%), and Internal Medicine (23%) while the least sought-after specialty is Chemical pathology (28%), followed by Medical Microbiology (27%) and Morbid Anatomy (24%). The most important factor considered by the respondents in choosing a particular specialty is their personal interest in that specialty, followed by financial prospects, comfortable lifestyle, and flexible working hours. Master of Public Health degree and postgraduate fellowship in Obstetrics and Gynaecology specialty are the career preferences for most of the final-year medical students in this study, and this is largely informed by their personal interest in these fields.

Exposure to patients' sample and prevalence of Hepatitis B and C virus infection among health-care workers in a Nigerian Tertiary Hospital.

Background: Hepatitis B and C lead to chronic disease in hundreds of millions of people and together constitute the most common cause of liver cirrhosis and cancer with attendant mortality. Objective: The objective of this study was to estimate the prevalence of hepatitis B and C virus infection among different categories of health-care workers, looking at the exposure to patients' samples and the prevalence rate among these categories of health workers. This will help to ascertain the risk and the need to pay more attention to preventive measures. Materials and Methods: This was a cross-sectional study conducted over a 2-year period among 217 health-care workers at the department of Haematology of the Federal Teaching Hospital, Ido-Ekiti, Nigeria. Respondents were randomly selected, and blood samples were taken for the hepatitis B and C screening. Data were analyzed using SPSS 20; bivariate analyses were done, and the level of statistical significance was set at P < 0.05. Results: A total of 13 (6.0%) tested positive for HBsAg. Analysis of the marital status of those that tested positive to Hepatitis B, revealed that the highest number (77%) was found among the married, while the singles and the divorced constitute 15.3% and 7.7% respectively. The nurses and nonhealth professionals (admin staff) constitute the highest positive yield of hepatitis B virus (HBV), followed by medical doctors and laboratory staff. The age of the respondent was found to have a statistically significant association with HBV serology (P < 0.05). Conclusion: There is a comparatively lower prevalence of HBsAg among the health-care workers who are directly exposed to patients' samples. The age of the respondent has a significant association with hepatitis B infection.

Comparative serologic profiles of hepatitis B Virus (HBV) between HIV/HBV co-infected and Hbv mono-infected patients in Ile-Ife, Nigeria.

Hepatitis B virus (HBV) infects about 2 billion people globally and accounts for mortality of about 800,000 from liver cirrhosis and hepatocellular carcinoma. Sub-Saharan Africa accounts for 70% of the Human Immunodeficiency Virus (HIV) global burden. HIV/HBV co-infection results in the early development of HBV complications, alterations of serological biomarkers of HBV. Two hundred and fifty patients with HIV/AIDS were screened for HBV and 20 (8%) were identified. The same number of HBV mono-infected individuals were recruited into the study and subsequently, HBV serological profiles which include HBsAg, HBsAb, HBeAg, HBeAb, HBcAbIgM, and HBcAbIgG were assayed using HBV ELISA kits. Mean age of patients in the HBV/HIV cohort was 45.5 years while the HBV mono-infected infected cohort was 30.5 years. The majority of the HBV/HIV co-infected individuals were females (85%). The frequency of HBeAg among HIV/HBV co-infected cohort was 25% and 15% for HBV mono-infected, while the frequency of HBeAb was higher (60%) among the cohort of HBV/HIV co-infected patients in comparison with the HBV mono-infected cohorts (50%). Two patients among the HIV/HBV co-infected cohort have the isolated anti-HBcAg serologic pattern. The study broadened the available evidence of comparative serologic profiles of Hepatitis B virus between cohorts of HBV/HIV co-infected individuals and HBV mono-infected patients in Nigeria.
