Background: p53 is a tumor suppressor gene. p53 expression in epithelial ovarian tumors (EOTs) is correlated with their biological behavior and predicts patient overall survival. However, there is a dearth of knowledge regarding p53 expression in these tumors among women from southwest Nigeria. Our study aimed to determine the patterns of p53 expression in various types of epithelial ovarian tumours., Methods: We conducted a retrospective study of epithelial ovarian tumours. We retrieved formalin-fixed, paraffin-embedded (FFPE) tissue blocks of previously diagnosed epithelial tumors from the departmental archive. We performed immunohistochemical analysis using p53 antibodies. We scored the expression and staining intensity of p53 as follows: negative (0), focal/weakly positive (1 +), and diffuse/strongly positive (2 +) on the basis of the recommended Cytomation scoring system., Results: The spectrum of p53 expression in the 51 histologically diagnosed cases revealed that 29 cases had no expression, consisting of 21 benign EOTs, two borderline EOTs, and six malignant EOTs. Nine cases exhibited wild-type expression, including six serous carcinomas, two mucinous carcinomas, and one signet ring cell carcinoma. p53 overexpression was observed in 13 patients overall, with 12 having serous carcinomas and one having endometrioid carcinoma. Among the 21 serous carcinoma patients, 28.6% (6 patients) presented with wild-type p53 expression, 57.1% (12 patients) presented with p53 overexpression, and 14.3% (three patients) presented negative p53 expression. There was a significant association between p53 expression and the histological grade of serous carcinoma., Conclusion: Most epithelial ovarian carcinomas in our hospital are high grade, with many serous carcinomas showing either p53 overexpression or loss of expression. This may contribute to the poor patient survival rate., Competing Interests: Declarations.

Background: Methamphetamine (MA) (Mkpurummiri) is seen as the most common, accessible and new drug of use/abuse in south east Nigeria. Despite the overwhelming evidence of the dire consequences of this drug to the users, there is lack of empirical research to determine its prevalence in this area where use is assumed to be common. This study aimed to determine the prevalence of MA use, characteristics of the users and the control measures., Methods: A descriptive cross-sectional survey research design was conducted from May through November 2023 among adolescents/adults at the age bracket of 15-64 years in the five states of south east, Nigeria. Three hundred and seventy-one (371) respondents were recruited using purposive/convenience sampling methods. A semi structured questionnaire was the instrument used. Data were analyzed using percentage, bivariate and multivariate logistics regression statistics. The Prevalence of MA was determined using percentages whereas the factors that are associated with MA use were expressed using multivariate logistics regression statistics AORs and 95%CIs. The level of significance was set at P < 0.05., Results: The prevalence of Methamphetamine (Mkpurummiri) was (21.8%). The most common reason for MA use was depression (86.5%), the most common route of administration was inhalation (64.9%). The most common characteristic of MA (Mkpurummiri) user was aggressive/violent behaviour (94.1%).The control measures were self-control (92.2%), parental monitoring (85.7%), drug education (83.1%) and legal control (80.8%). The multivariate logistics regression statistics AOR shows that off-campus were 3 times (AOR = 0.298; CI = 0.12-0.73 P = 0.008), family house 4 times (AOR = 0.241; CI = 0.09-0.65; P = 0.005 ≤ 0.05 ) less likely than on-campus to predict MA use. Recently married were 3.25 times (aOR = 3.25; CI = 1.47-7.18), divorced 3.45 times (aOR = 3.45; CI = 1.23-9.58), polygamy 2.3 times (aOR = 2.3; CI = 1.08-4.90; P = 0.031 ≤ 0.05 ), tradition 4.44 times (aOR = 4.44; CI = 1.77-11.15; P = 0.001 ≤ 0.05 ) , more likely than others to use MA., Conclusions: MA use prevalence was relatively high, and marital status, living arrangements, family type and religion were the predictors. These findings underscore the need for concerted effort among the relevant government agencies, community stakeholders, families, religious bodies and school authorities to designing MA use policy/laws with special focus on adopting the punitive measure used in checking cocaine users. This may help to arrest and prosecute the manufacturers, distributors and users of MA., (© 2024. The Author(s).)

Introduction: There is increasing evidence in favor of enhancing adherence to antiretroviral therapy (ART) in people living with HIV (PLHIV) through mobile health (mHealth) assessment and intervention. The study aims to establish the willingness to adopt mobile phone technology to enhance adherence to ART among PLHIV., Methods: The Researchers adopted a cross-sectional survey. Systematic sampling was employed in selecting 237 PLHIV in the HIV clinic for adults at Ido-Ekiti's Federal Teaching Hospital, Nigeria. Data collection was via a 33-item semi-structured questionnaire administered by the interviewer. Information collected via the questionnaire included details on ownership of mobile phone technology, its usage, and willingness to use it to improve adherence to HIV medication. Descriptive statistics coupled with multivariate regression was employed in analyzing data, with the level of significance at 5%., Results: The respondent's had a mean ±SD age of 46.6 ±10 years. Most of the participants were female (77.6%), and have been on ART for over 2years (88.2%). The vast majority of study participants 233 (98.3%) owned a mobile phone. 168 (70.9%) of them were willing to embrace mHealth interventions on medication adherence. Some of the factors influencing the respondent's willingness to receive the intervention were older age (OR = 0.05, 95%Cl:[0.01-0.24]), having formal education (OR = 7.12, 95%Cl:[3.01-16.53]), being diagnosed over 10years ago (OR = 15.63, 95%Cl:[3.02-80.83]) and previous use of phone to send text messages, record video, access the internet, send email and search the internet for health-related information (OR = 2.2, 95%Cl:[1.2-3.9]; OR = 1.8, 95%Cl:[1.0-3.2]; OR = 2.5, 95%Cl:[1.4-4.7]; OR = 2.7, 95%Cl:[1.2-5.5] and OR = 2.0, 95%Cl:[1.0-3.8]) respectively., Conclusion: Many of the PLHIV had a cellphone and expressed willingness on their part to use it in receiving reminders to take their medication. Older age, formal education and internet users were significantly more willing to get reminders to take their medication., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ojo et al.

Background: Paediatric solid tumours, both benign and malignant, present significant health challenges, particularly in Sub-Saharan Africa where comprehensive data is limited. This study aims to elucidate the prevalence, distribution, and treatment outcomes of paediatric solid neoplasms in a tertiary hospital in South-East Nigeria over a seven-year period., Methods: A retrospective cohort study was conducted at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Clinical details and histological slides of confirmed cases from January 2016 to December 2022 were reviewed. Data extraction focused on socio-demographic variables and treatment outcomes, analysed using statistical methods., Results: The study included 293 children diagnosed with solid tumours (58.1% malignant, 41.9% benign), with a female predominance (61.8%). The median age at diagnosis was 12 years. Fibroadenoma was the most common benign tumour (61.8% of benign cases), while non-Hodgkin lymphoma was the predominant malignant tumour (18.2% of malignant cases). Treatment abandonment rates differed significantly between benign (13.8%) and malignant (51.2%) tumours. Significant associations were found between treatment outcomes and factors such as gender (p = 0.0001 for benign tumours), age category (p = 0.0001 for benign tumours), and specific diagnoses (p = 0.0001 for both benign and malignant tumours)., Conclusion: This study underscores the substantial burden of paediatric solid tumours in South-East Nigeria and highlights the critical need for improved treatment adherence strategies, particularly for malignant cases. The findings emphasize the importance of tailored interventions based on tumour type, age, and gender. These insights can inform future research, policy formulation, and healthcare strategies aimed at enhancing the management and outcomes of paediatric solid neoplasms in resource-limited settings., (© 2024.

Background: An accurate diagnosis is the bedrock of the treatment of skin diseases. This study aimed to evaluate the correlation between clinical and pathological diagnosis of patients with skin disorders seen in dermatology units of Federal Medical Centre (FMC), Asaba, Delta State, and the University of Benin Teaching Hospital (UBTH), South-South Nigeria between 2019 - 2021., Material and Methods: This was a retrospective study of the charts of all patients seen in the dermatology units of FMC Asaba and UBTH who had skin biopsies for various skin diseases from 2019 to 2021. Biodata, clinical information, diagnosis, and histology results of these patients were collected using a questionnaire. One hundred and sixty-two (162) patients were excluded on account of the absence of a clinical diagnosis and a pathological conclusion of insufficient tissue sample., Results: 356 skin biopsies were included. The male-to-female ratio was 1:1.18 and most patients were aged 40 to 49 years 74 (20.8%) with a mean age of 38.28± 19.19. Papulosquamous skin disorders accounted for 141 of the clinical diagnoses (39.0%) Among the histology request forms filled, only 69 (19.4% ) had detailed clinical history. Clinico-pathological concordance (CPC) was recorded in 214 (60.1%) cases and discordance in 142 (39.9%), both the highest concordance and discordance percentages were among papulosquamous diseases (45.1% and 31.5% respectively). There was no significant association between the completeness of documentation of patient's clinical information and clinicopathological concordance., Conclusion: Although the CPC was above 50% in this study, better modalities of communication between dermatologists and pathologists is desired., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2024 by West African Journal of Medicine.)

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., (Copyright © 2023 Copyright: © 2023 Annals of African Medicine.)

Background and Objective: The demonstration of HER2 in gastric adenocarcinoma (GA) tissues by immunohistochemistry assists in deciding whether targeted therapy would optimise the treatment of GA patients who are HER2 positive. However, this has not been extensively studied in our patients hence the need for this study., Methods: Recipient tissue microarray blocks were constructed from donor archival formalin fixed paraffin embedded gastric tumour tissue from 80 patients seen over a period of 17 years in a retrospective descriptive study. Slides cut from these blocks were stained with antihuman HER2 antibody by immunohistochemistry and scored using the trastuzumab in gastric adenocarcinomas (ToGA) trial criteria. Data on age, gender, site of lesion and histological subtype of the gastric adenocarcinomas were also retrieved and reviewed., Results: Eighty cases (52 males and 28 females; male to female ratio of 1.9:1), 55.65 ±13.50 years (modal age group 60-69 years), were studied. Most tumours (91.2%) involved the distal parts (pylorus, antrum and body) with a few (8.8%) involving the proximal part (cardia and fundus) of the stomach. HER2 was overexpressed in a total of 6 (7.5%) cases only. Two of seven (28.6%) proximal tumours showed HER2 positivity whereas only 4 of 73 (5.5%) of the distal tumours showed HER2 positivity., Conclusion: We had only a slightly lower HER2 overexpression rate than in studies from many other parts of the world. The observed overexpression was significantly higher in proximal than distally located tumours suggesting that distal tumours are less likely to respond to Trastuzumab than proximal tumours. The known association of distal gastric tumours with Helicobacter pylori infection probably provides for a possible difference in the molecular aetiopathogenesis of GAs by site of occurrence. The exact mechanisms for proximal gastric carcinogenesis remain to be more clearly elucidated. More studies, including clinical trials with larger sample sizes, are recommended to elucidate this differential expression of HER2 in gastric adenocarcinoma., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2024 by West African Journal of Medicine.)

Background: High HIV prevalence, and lack of organized screening for the indigent population receiving care and treatment within HIV clinics in low-resource settings increases cervical cancer incidence. We sought to determine predictors of cervical precancer in women living with HIV and receiving cervical cancer screening in Jos, Nigeria., Methods: A cross-sectional study of women living with HIV and receiving care and treatment in adult HIV/AIDS clinics in Jos-Metropolis, Nigeria between June 2020 and April 2023. Ethical approvals were obtained from the ethics committee in Jos, Nigeria and Northwestern University IRB, USA. Informed consent was obtained from eligible participants, and data on socio-demographics, cancer risk factors, and cytology reports were collected. The outcome variables were cervical precancer lesions. The independent variables were prior Pap smear status, socio-demographics, income, educational, and other reproductive health factors. Descriptive statistics was done to obtain means ± sd, frequencies, and percentages for the variables. Univariate and bivariate analyses were done to determine predictors of cervical dysplasia. Analyses were performed using R software., Results: Of 957 women screened, 570 were living with HIV and 566 women had cytology report and were included in the final analysis. The mean age was 45.08 ± 8.89 years and 81.6% had no prior evidence of Pap test (under-screened). Prevalence of cervical dysplasia was 24% (mild and severe dysplasia were 12.9% and 11.1%, respectively). Age above 45 years (aOR = 3.48, p = 0.009), postmenopausal status (aOR = 7.69, p = 0.000), and women with no history of prior IUCD use (aOR = 5.94, p = 0.0001), were predictors for severe dysplasia. Women who had history of STI (aOR = 0.17, p = 0.000), prior use of IUCD (aOR = 0.32, p = 0.004), prior use of condom (aOR = 2.50, p = 0.003) and had co-morbidities (aOR = 0.46, p = 0.009) were more likely to have had a Pap test in the past., Conclusions: The majority of indigent women receiving care at HIV clinics had their first Pap test screening, and lack of organized screening among older and post-menopausal women with HIV, puts women at a higher risk of developing severe cervical precancer lesions., (© 2024.

Objectives: To assess the knowledge and acceptability of COVID-19 vaccines among HCWs., Design: A descriptive cross-sectional study was conducted in March 2021 among eligible HCWs using a self-administered questionnaire., Setting: The study was conducted in a southern Nigerian tertiary hospital., Participants: All HCWs not on annual or study leave were eligible to participate. The number of HCWs in each occupational category was determined by proportional allocation. HCWs were selected by stratified sampling technique., Main Outcome Measures: Knowledge of COVID-19 vaccines was assessed using 25 questions. The minimum and maximum scores were 0 and 25, respectively. Scores were converted to percentages. Scores of 50% and above were rated as good knowledge. Participants were also asked if they were willing to receive the vaccine., Results: The mean age of 512 participating HCWs was 33.4±7.8 with an M:F ratio of 1:1.1. Overall, 399 (76.6%) had good knowledge. Occupation and exposure to COVID-19 were predictors of knowledge. Three hundred and twenty-eight respondents (63.0%) were willing to take the vaccine. Predictors of willingness to accept vaccination were age, sex, number of years in employment and knowledge about the vaccines (p< 0.05)., Conclusions: Most HCWs had good knowledge and were disposed to accepting the COVID-19 vaccine. Educational interventions are necessary to improve HCWs knowledge as they may provide vaccine-related information to the general public., Funding: None declared., Competing Interests: Conflict of interest: None declared, (Copyright © The Author(s).)

Background: Renal cell carcinoma is the most lethal urological cancer and contributes significantly to morbidity and mortality due to cancers of the urogenital tract. In routine diagnostic surgical pathology practice of renal tumours, immunohistochemistry is a helpful ancillary technique after routine H & E. The role of renal immunohistochemistry is explored in this study., Materials and Methods: The paraffin-embedded tissue blocks of all the confirmed cases of renal cell carcinoma seen at the University College Hospital (UCH), Ibadan, during the 10-year study period of 2007 to 2016 were retrieved, sectioned and immunohistochemistry done using monoclonal antibodies for EMA, Vimentin and CD117 following standard protocols. Frequency statistics and chi-square were applied to data to determine proportions and associations using the Statistical Package for the Social Sciences (SPSS) version 23., Results: A total of 48 cases of renal cell carcinoma were seen within the study period that met the inclusion criteria for the study. The age range of the patients was between 3 to 76 years with an average age of 44.17 years. The male-to-female ratio was 1:1.3. Fuhrman Grade 2 nuclei were predominant (43.75%) while Fuhrman Grade 4 nuclei had the lowest frequency (6.25%). EMAstaining patterns for the different histological patterns of RCC showed no statistically significant difference while Vimentin and CD117 staining patterns showed a statistically significant difference. There was no statistically significant difference observed between the staining patterns of all three markers and the nuclear grades of the cases of RCC., Conclusion: This study demonstrated the usefulness of Vimentin and CD117 in differentiating chromophobe variant of renal cell carcinoma from other subtypes while EMA showed variable expression across the various subtypes., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2023 by West African Journal of Medicine.)

Aims: Gastrointestinal stromal tumors (GISTs) are neoplastic lesions that primarily affect the digestive tract and develop from interstitial cells of Cajal. These lesions require histopathological and immunohistochemical characterization due to their malignant potential and personalized treatment. In this investigation, the sex, age, lesional sites of origin, histopathological types, the prevalence of human epidermal growth factor receptors (HER-2) expression, prognostic indices (based on tumor size and mitotic figures), expression of CD117 and DOG1, and characteristics of patients with GIST were all characterized., Materials and Methods: This was a retrospective cross-sectional analysis of GIST cases seen at four tertiary health-care centers in Nigeria over a 10-year period (2008-2017) and investigated utilizing histopathological and immunohistochemical (CD117, DOG1, and HER-2) methods., Results: In this investigation, there were twenty GIST cases. Notably, the majority (40%) of the cases had tumors with sizes between 7.0 and 8.0 cm; the stomach was the most frequent site (70%) and the spindle cell type of GIST was the most prevalent (80%) histopathological type. In addition, the stomach was significantly associated with GIST as an origin site (with a P = 0.001), and 100% and 50% of these tumors were immunoreactive with CD117 and DOG1, respectively., Conclusions: In our study, GISTs most frequently develop in the stomach, and CD117 and DOG1 are essential for correctly diagnosing these tumors. However, HER-2 immunoreactivity is a predictive marker of survival for personalized care., Competing Interests: None

Background: High risk human papillomaviruses (HR-HPV) have a causal role in cervical oncogenesis, and HIV-mediated immune suppression allows HR-HPV to persist. We studied whether vaginal microbiome community state types (CSTs) are associated with high-grade precancer and/or invasive cervical cancer (HSIL/ICC)., Methods: This was a cross-sectional study of adult women with cervical cancer screening (CCS) at the Jos University Teaching Hospital (JUTH) in Jos, Nigeria, between January 2020 and February 2022. Cervical swabs underwent HPV genotyping (Anyplex™ II HPV28). Cervico-vaginal lavage (CVL) sample was collected for 16 S rRNA gene amplicon sequencing. We used multivariable logistic regression modelling to assess associations between CSTs and other factors associated with HSIL/ICC., Results: We enrolled 155 eligible participants, 151 with microbiome data for this analysis. Women were median age 52 (IQR:43-58), 47.7% HIV positive, and 58.1% with HSIL/ICC. Of the 138 with HPV data, 40.6% were negative for HPV, 10.1% had low-risk HPV, 26.8% had single HR-HPV, and 22.5% had multiple HR-HPV types. The overall prevalence of any HR-HPV type (single and multiple) was 49.3%, with a higher proportion in women with HSIL/ICC (NILM 31.6%, LSIL 46.5%, HSIL 40.8%, and 81.5% ICC; p = 0.007). Women with HIV were more likely to have HSIL/ICC (70.3% vs. 29.7% among women without HIV). In crude and multivariable analysis CST was not associated with cervical pathology (CST-III aOR = 1.13, CST-IV aOR = 1.31). However, in the presence of HR-HPV CST-III (aOR = 6.7) and CST-IV (aOR = 3.6) showed positive association with HSIL/ICC., Conclusion: Vaginal microbiome CSTs were not significantly associated with HSIL/ICC. Our findings suggest however, that CST could be helpful in identifying women with HSIL/ICC and particularly those with HR-HPV. Characterization of CSTs using point-of-care molecular testing in women with HR-HPV should be studied as an approach to improve early detection and cervical cancer prevention. Future longitudinal research will improve our understanding of the temporal effect of non-optimal CST, HR-HPV, and other factors in cervical cancer development, prevention, and control., (© 2023.

Background: Over the years, epidemiological surveys have established that the five leading cancers in Africa (in descending order of prevalence) are cancers of the breast, cervix, prostate, liver, and colorectum. [1] However, a 10-year retrospective review of cases performed at the University of Ilorin Teaching Hospital (UITH) revealed some changes in the cancer incidence pattern in this region., Aims: The aim of the study was to determine the distribution of cancers managed at the UITH, a tertiary health care center in North Central Nigeria, in the past 10 years and create awareness of changing cancer prevalence patterns in this region., Materials and Method: This was a retrospective review of cancer epidemiology at UITH over a period of 10 years. Confirmed cancer cases within this period were extracted from the data in the Department of Anatomic Pathology and the Cancer registry. Descriptive and inferential statistics were applied to obtain rates and proportions for both sexes., Results: There were 2430 confirmed cases of cancer during the study period from January 2011 to December 2020. Out of these cases, 1310 (54%) were seen in females and 1120 (46%) were seen in males. The most common cancer recorded (in total) was prostate cancer, which accounted for 18% of all cases, constituting approximately one in six of all cancer cases. This was followed closely by breast cancer (16.6%). The most commonly diagnosed cancer in males was prostate cancer (four in ten cancer cases in males), whereas in females, it was breast cancer (approximately three in ten cancer cases in females). Cancers of the lungs and liver were rare in both sexes in this study. In children, the most common malignancies were retinoblastoma (38.3%), non-Hodgkin lymphomas (16.8%), and nephroblastoma (12.8%)., Conclusion: There is a changing trend in cancer cases with some cancer cases now predominating compared to previous years. This may be because of increased awareness and/or better medical screening and diagnostic techniques., Competing Interests: None

Background: Ocular surface squamous neoplasia (OSSN) is a heterogeneous group of proliferative squamous lesions on the ocular surface with varying biologic behaviours. This study aims to report the clinical profile and pathological characteristics of cases of OSSN seen at a tertiary referral centre in North West Nigeria., Methods: A retrospective review of all cases of OSSN diagnosed over a 10-year period was done., Results: OSSN accounted for 68 out of 91 ocular surface lesions affecting twice as many males as females and a peak incidence in the 30-39 years age group. They frequently presented as higher-grade and higher-stage lesions with invasive squamous cell carcinoma being the most frequently diagnosed OSSN. They also frequently showed an association with HIV infection and a relatively long duration of symptoms before presentation., Conclusion: OSSN occurs in a relatively young age group in our environment. Certain clinical and epidemiological features appear to predict the occurrence of higher-grade lesions, and this may help in the clinical prediction of likely pathologic grade and/or biologic behaviour of these lesions., (© 2022.

Family is the microcosm of a larger society that provides care that shapes the behavior of children. However, the different levels of attention children receive from their parents may affect their behaviour and self-esteem, which can lead to them being more vulnerable to sexual harassment. An institutional-based cross-sectional survey was conducted from March - August 2021, to assess the relationship between family birth order and prevalence of sexual harassment. The multistage sampling procedure was used to draw 1070 participants. The data was analyzed using percentages, mean, and multivariate logistic regression statistics. The multivariate logistic regression was used to estimate adjusted odds ratios (AOR) along with 95% confidence intervals (CIs). The level of significance was set at P < 0.05. The findings revealed prevalence (73.6%) of sexual harassment, and the two forms such as verbal ( = 2.63) and non-verbal sexual harassment ( = 2.56) were high. The multivariate logistic regression odds ratios adjusted shows that the middle born were approximately 2 folds (AOR = 1.62; CI = 1.14 - 2.30; P = 0.008 0.05) more likely to predict sexual harassment. The study recommended amongst others that parents in South Eastern Nigeria should refrain from given special attention to a particular child as this may predispose the unfavoured child to sexual harassment.

Background: Reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has important public health implications pertaining to herd immunity and durability of protection from vaccines. A small but growing number of cases have been reported globally but none from Africa. This is due, in part, to adherence to definitions based on genetic sequencing, the capabilities of which are in short supply on the continent., Methods: Based on epidemiological and clinical parameters, we report the first two cases of SARS-CoV-2 reinfection from a Nigerian tertiary hospital managing coronavirus disease 2019 (COVID-19) patients., Result: Two cases of SARS-CoV-2 reinfection were seen in December, 2020 and January, 2021. Both were males associated with a healthcare setting and aged 37 and 38 years respectively. The number of days between the first infection and the second ranged from 160-196 days. Symptoms ranged from mild to moderate and they recovered without sequelae., Conclusion: Public health action, including risk communication and reinfection surveillance backed by genomic sequencing, is advocated., Competing Interests: The Authors declare that no competing interest exists., (Copyright © 2022 by West African Journal of Medicine.)

Background: Malignant melanoma (MM) is the most lethal of all cutaneous malignancies, accounting for about 79% of skin cancer related deaths. In blacks, it is associated with greater morbidity and mortality compared to Caucasians. Breslow thickness and ulceration status are two of the most important histopathologic prognostic factors in MM. No study on MM in Nigeria has however examined these factors., Methods: Formalin-fixed paraffin-embedded (FFPE) tissue blocks and corresponding Haematoxylin and Eosin (H&E) stained slides of all confirmed cases of MM from January 2005 to December 2014 in the AMP Department of Lagos University Teaching Hospital (LUTH) were retrieved., Results: Fifty-two MM cases were histologically diagnosed in LUTH during the study period which represented 1.0% of total solid malignancies. Forty-three of these occurred in the skin accounting for 19.7% of all skin malignancies and making MM the 3rd commonest skin malignancy after squamous cell carcinoma (SCC) and kaposi sarcoma (KS). Eighty eight percent (88%) of the tumour were in Clark's stage IV and V while 84% had Breslow thickness >4mm. Ulceration was present in 67%. The Clark's level and Breslow thickness were correlated with the ulceration status of the tumour. There is significant correlation between the Breslow thickness and ulceration with p-value < 0.05 while there is no significant association between the Clark's level and ulceration., Conclusion: MM constituted a significant proportion of skin malignancy in LUTH and majority of the cases present at an advanced stage. Breslow thickness and ulceration statuses of the tumour are important histopathologic parameters that should be reported in all MM biopsies., Competing Interests: The Authors declare that no competing interest exists., (Copyright © 2022 by West African Journal of Medicine.)

Introduction: the death care of deceased bodies of confirmed COVID-19 cases is a critical component of holistic healthcare provision for COVID-19 cases particularly from the public health perspective of infection prevention/control. Regrettably, there is a dearth of research-based information on the management (death care) of COVID-19 deceased bodies. Thus, we aimed to determine the preservation/storage death care practices and procedures in accordance with infection prevention/control measures used for deceased bodies of suspected/confirmed COVID-19 cases deposited in our mortuary and explore their antemortem age/sex distribution., Methods: a retrospective hospital-based cross-sectional survey done at the mortuary unit of Department of Histopathology, University of Uyo Teaching Hospital (UUTH), Uyo, Akwa Ibom State (covering January 2020 to September 2021). Our study participants were all deceased bodies of suspected/confirmed COVID-19 cases deposited in/cared for at UUTH mortuary within this period., Results: we found 28 suspected/confirmed COVID-19 deceased bodies, of which 51.86% were within the 6 th and 7 t h decade of life and 71.43% were males (M/F = 2.5/1). They constituted 5.93% of the deceased bodies deposited in UUTH mortuary within this period. All (100%) were embalmed, and 75% were embalmed by immersion. The peak periods of their deposition were within the first halves of the two years affected by the COVID-19 pandemic., Conclusion: we provided death care (mainly through embalmment) for deceased bodies of suspected/confirmed COVID-19 cases in our resource poor setting using locally derived innovative means while still adhering to infection prevention/control measures to protect our death care workers in the mortuary., Competing Interests: The authors declare no competing interests., (Copyright: Uchechukwu Brian Eziagu et al.)

Background: The clinical and pathologic spectrums of goitres are wide. Even though Nigeria's Federal Capital Territory is within the geographic goitre bed, there is a paucity of thyroidrelated data from this region. The objective of this study was to determine the clinical presentation, management and outcomes of patients with goitre operated-on at the Department of Surgery, Asokoro District Hospital, in Abuja, Nigeria., Methodology: This is a retrospective study involving patients managed between January 2001 and December 2015. Data were extracted from patients' medical records, operation registers, and histopathology records. Variables were; age, sex, diagnosis, types of operation performed, post-operative complications and histological findings. All patients had general anaesthesia via cuffed endotracheal intubation and the surgical technique used was skin crease transverse collar stud incision., Results: One hundred and thirty four (134) patients were involved in the study: 124(92.5%) were females and 10(7.5%) males. Mean age was 38years±11.0SD. Seventy-seven (57.5%) patients had simple multi-nodular goitre, followed by simple left nodular goitre 20(14.9%) and simple right nodular goitre 17(12.7%). One hundred and twenty-one (90.5%) patients did not have any complications. On histologic examination, most of the lesions were multinodular goitres 60(44.8%), followed by simple nodular goitres, 23(17.2%). Follicular adenoma was the commonest neoplastic variant accounting for 12(9.1%) cases., Conclusion: The pattern of goitres in Abuja simulates that from other parts of Nigeria and many other African countries though with fewer malignancies in the present study. The management and outcome of goitres in Asokoro District Hospital Abuja is comparable to those obtained from other centres in Nigeria. Pre-and postoperative complications were also minimal., Competing Interests: The Authors declare that no competing interest exists., (Copyright © 2022 by West African Journal of Medicine.)

Introduction: The medicolegal auditing of the pattern of death among detainees in police and prison custody is a useful tool in planning for quality care to be given to detainees, who do not have access to stable health care as seen in the free world., Aim: To retrospectively study the peculiarities of custodial deaths (CD), among individuals detained in police and prison custody in Uyo, South-Soth Nigeria and to suggest preventive measures., Materials and Methods: This is a review of all the post mortem examinations (PME) that were performed on detainees that died in police or prison custody over 4 years., Results: They were 9 detainees aged between 22-44 years with an average age of 31.1 years. All the detainees were males. Six (66.7%) persons died in police custody, while 2 (22.2%) died in prison custody and 1 (11.1%) person died in police clinic. The shortest duration of detention before death was 1 day (24 hours) and the longest 80 days. Marks of torture were seen in 2 (22.2%) cases. The cause of death was seen in 8 (88.9%) cases. In 1 (11.1%) no anatomic pathologic cause of death was seen. The manner of death was natural in 4 (44.4%), homicide 3 (33.3%), accidental 1 (11.1%) and undetermined 1 (11.1%). The 4 natural causes of death were 2 cases of hypertensive cardiovascular disease, a case of myocardial infarction and a case of alcoholic hepatitis. The cause of death in all the homicidal and accidental cases were massive intracranial bleeding., Conclusion: Natural death is the most common manner of death among detainees in Uyo., Competing Interests: The authors certifies that there is no conflict of interest in connection with the submitted article., (Copyright © 2021 by West African Journal of Medicine.)

Background: Worldwide, liver disease is a leading cause of morbidity and mortality. Its pattern can be updated by periodic data collection and analysis., Objective: To update the existing histopathological pattern of liver diseases at the University of Benin Teaching Hospital, Benin City, Edo state, Nigeria., Materials and Methods: This was a descriptive cross-sectional retrospective study of all cases of liver biopsies diagnosed histologically between 1st of January, 2012 to 31st of December, 2019. Data was obtained from the surgical pathology register and the age, sex and pathological diagnoses of the lesions analysed., Results: Liver biopsies were reported for a total of 68 patients during the 8-year study period. The ages of the patients ranged from 2 months to 75 years with a mean age and standard deviation of 28.88 ± 23.21 years. The 3 most common histopathological diagnoses were infectious liver disease (38.23%), malignant neoplastic lesions (26.47%) and cholestatic liver disease (16.17%), with the peak age of infectious liver disease (30-39years) preceding that of malignant liver disease (60-69years) by 3 decades., Conclusion: This study shows that chronic hepatitis B infection was the commonest histologic finding of liver biopsies at the University of Benin Teaching Hospital. Screening, vaccination and prompt treatment of hepatitis B infection are recommended to reduce the burden of liver disease. Liver biopsies have been updated to include biliary cirrhosis, biliary atresia, cystic liver diseases and glycogen storage disease thus expanding the scope of histopathological diagnosis that could be made on liver tissue biopsies in this environment., Competing Interests: The authors certifies that there is no conflict of interest in connection with the submitted article., (Copyright © 2021 by West African Journal of Medicine.)

The diagnosis of thoracic endometriosis (TE) is challenging, hence resulting in under-diagnosis as well as long delays before arriving at a correct definitive diagnosis. Our aim is to review the histopathological findings in TE, summarise the diagnostic features, identify any major histo-morphological indicator(s) hitherto unrecognised as such, suggest diagnostic criteria; all with the aim of improving the diagnostic capacity and reducing observer error even where the clinical suspicion is low. A case-control study in which a search in the pathology archives of a referral hospital over a 10-year period was conducted. Twenty-six cases of TE were identified, reviewed, and compared with a control population of 48 cases taken from common benign thoracic diseases. Nine notable histological features were identified in varying permutations in the test group, namely: endometrioid glands, lymphoid clusters, ceroid macrophages, siderophages, cholesterol crystals, capillary congestion, multinucleated giant cells, smooth muscle bundles and fibrosis. The first 6 features were frequent; each being present in over 13 (13/26; 50%) test cases. The first 8 features showed significant association with TE by the Chi-squared test (P<0.05). In this group, the strength of association is high for the first 4 features (Cramér's V≥0.5). The presence of ceroid macrophages is shown to be a novel key feature, previously unrecognised as such, for the identification of TE. The presence of any three of four features including endometrioid glands, lymphoid clusters, ceroid macrophages and siderophages is a suggested criterion for the definitive diagnosis of TE., Competing Interests: The authors have declared that no competing interests exist.

Background: We assessed clinical parameters in patients confirmed to have COVID-19 in relation to arterial hypoxaemia and survival., Methodology: This was a retrospective chart review of patients who were confirmed positive for SARS-CoV-2 virus by Real Time-Polymerase Chain Reaction (RT-PCR) testing. Data extracted from patients' case files included patient demographics, presenting symptoms, provisional diagnoses, and outcomes of hospitalisation. Descriptive variables were summarized; proportions were compared using Chi-square tests, and independent predictors of mortality were assessed using multivariate regression analysis. A p-value of < 0.05 was considered as statistically significant., Results: There were a total of 61 patients with positive RT-PCR testing: mean age ± SD (minimum - maximum) was 53.0 ± 18.5 (5 months - 90) years. Persons aged 60 years and above were the largest group (n=24, 39.3%). More than half were male (n=35, 57.4%); about 43% had one morbidity; 41.0% had at least two co-morbidities. The mean (SD) arterial oxygen saturation (SpO2) was 86.9% ± 16.7. Patients who were clinically dyspnoeic at presentation, and who had co-morbidities were significantly more hypoxaemic (p = 0.026 and 0.04, respectively). Significantly more patients who had normal oxygen saturation at presentation survived (p = 0.006). None of these variables was an independent predictor of mortality, however., Conclusion: Arterial hypoxaemia was significantly associated with dyspnoea and underlying disease, and normal oxygen saturation at presentation was significantly associated with survival. Hospital managers and clinicians may thus prioritize routine pulse oximetry, supplemental oxygen therapy and management of co-morbidities in the COVID-19 fight.

COVID-19 in healthcare workers (HCWs) can result in nosocomial transmission, depletion in available workforce, and enhanced community transmission. This article describes surveillance for COVID-19 in HCWs at a tertiary healthcare facility, and documents the outcomes. A descriptive cross-sectional study of all HCWs identified from surveillance for COVID-19 from March 31 to August 31, 2020 was conducted. Healthcare workers were categorized as high risk and low risk using an adapted WHO Risk Assessment tool. Nasopharyngeal and oropharyngeal swab specimens obtained from high-risk subjects were tested by a reverse transcriptase PCR method. Data were analyzed with IBM SPSS version 25.0 software (IBM SPSS Statistics for Windows, Version 25.0, Armonk, NY), and results were presented as frequencies and percentages. The level of significance was set at P < 0.05. During 5 months of surveillance, 1,466 HCWs with a mean age of 38.1 ± 9.7 years were identified as contacts. On risk assessment, 328 (22.4%) were adjudged high risk. High risk was associated with increasing age (P < 0.001), male gender (P = 0.001), and nonclinical staff (P = 0.002). Following testing, 78 (5.3%) in the high-risk category were confirmed to have COVID-19. There was no record of COVID-19 in HCWs adjudged low risk. Forty-four (56.4%) cases were epidemiologically linked to the community, 20 (25.7%) to patients, and 14 (17.9%) to another HCW. Surveillance and risk assessment are crucial to COVID-19 response in healthcare facilities and revealed HCW infections with predominantly nonoccupational epidemiological links in this study.

Background: In the absence of effective vaccines and definitive treatment, non-pharmaceutical interventions, also known as community mitigation strategies (CMS), are needed to reduce the transmission of respiratory virus infections such as coronavirus disease 2019 (COVID-19). However, the effectiveness of these strategies depends on a knowledgeable population cooperating and adhering strictly to recommended strategies., Objective: The objective of the study was to determine the knowledge and adherence to CMS against COVID-19 in Benin City, the capital of Edo State, Nigeria., Materials and Methods: A descriptive cross-sectional study was conducted amongst adult residents in Benin City using a self-administered questionnaire for data collection. Eighteen questions addressed knowledge of CMS, while adherence was assessed using 14 questions on a graded scale. Each correct answer was scored giving maximum and minimum scores of 18 and 0 for knowledge and 28 and 0 for adherence, respectively. Scores were converted to percentages with scores 70% and above adjudged as good knowledge of CMS and scores 50% and above adjudged as good adherence to CMS. Data were analysed with IBM SPSS version 25.0 software. The level of significance was set at P < 0.05., Results: The mean age (standard deviation) of 577 respondents who participated in the study was 32.5 ± 11.7 years. Overall, 532 (92.2%) respondents had good knowledge, while only 165 (28.6%) demonstrated good compliance with CMS against COVID-19. Christianity was a statistically significant predictor of knowledge of CMS. Income was found to be a significant predictor of adherence to CMS amongst respondents., Conclusion: Respondents demonstrated good knowledge but poor adherence with CMS against COVID-19 in Benin City, Edo State. Behaviour change communication is advocated to ensure that mitigation strategies are effective., Competing Interests: None

Background: Information pertaining to the clinical characteristics of COVID-19 in sub-Saharan Africa remains sparse. In Nigeria, it is limited to few isolated reports and case series confined to the early phase of the outbreak. The objective of this study is to describe the presenting characteristics, co-morbidities and outcomes of Nigerian patients managed over a 3-month period in a tertiary hospital., Methods: This was a descriptive cross-sectional study involving the total population of patients with laboratory confirmed diagnosis of COVID-19 in the University of Benin Teaching Hospital, Edo State, Nigeria from March 31 to June 30, 2020. Data was collected using a review of patients' records. Analysis was by IBM SPSS version 25.0. The level of significance was set at p < 0.05., Results: A total of 173 patients with mean age (SD) 50.7± 20.1 years were managed. One hundred and five (60.7%) were males and the commonest age group was 20-39 years (34.7%). The commonest presenting symptoms were fever, cough and malaise found in 103 (71.5%), 101 (70.1%) and 63 (43.8%) patients respectively. Twenty-five (14.5%) patients had severe disease; 60 (34.7%) had underlying medical conditions mostly hypertension and diabetes mellitus. Outcome analyses showed 117 (67.6%) discharges, 45 (26.0%) deaths, 10 (5.8%) discharges against medical advice, and 1 (0.6%) transfer to another facility. Male sex (p=0.044), increasing age (p<0.001), presence of symptoms (p=0.010), presence of co-morbidities (p=0.010) and non-healthcare worker status (p< 0.001) were significantly associated with mortality., Conclusion: The first epidemiological and clinical summary of COVID-19 cases in Edo state, Nigeria over a three-month period is presented showing globally recognized patterns of male predilection and higher mortality with increasing age and co-morbidity.

Introduction: breast cancer is the most common malignancy in females worldwide and a major cause of cancer-related deaths in both developing and developed countries. The objective of this study was to determine the socio-demographics, pattern of presentation and management outcome of breast cancer patients., Methods: clinical records of confirmed breast cancer patients between January 2011 and December 2015 at the Ekiti State University Teaching Hospital, Ado-Ekiti, Nigeria were reviewed., Results: eighty two breast cancer patients were seen. Their ages ranged from 26-95 years (mean 48.9 ± 14.9 years, median 47.5 years). Eighty one (98.8%) were females and the majority (65.4%) were premenopausal. The peak age of incidence was in the 4 th decade. All patients presented with breast lump with mean duration of 9.49±6.1 months and size ranging from 2 to 16cm (mean 7.9±3.4 cm). Ten (12.2%) patients presented early, 61 (74.4%) were locally advanced while 11 (13.4%) had distant metastases. Fifty one (62.2%) patients had mastectomy. Only 38 (46.3%) patients completed six courses of chemotherapy. None had immunohistochemistry but they all routinely took tamoxifen. Only 4 (4.9%) had radiotherapy. Nineteen (23.2%) died within a year of presentation. The follow-up period ranged between 1 and 44 months (mean, 10.3 months). Thirty one (37.8%), 19 (23.2%) and 8 (9.8%) patients were seen during the first, second and third year of follow up respectively., Conclusion: breast cancer mostly affects young premenopausal women presenting in advanced stage in our setting. The generally poor outcome is not unconnected with late presentation and inadequate diagnostic and treatment facilities., Competing Interests: The authors declare no competing interests., (Copyright: Julius Gbenga Olaogun et al.)

Introduction: this report is a documentation of a staff risk stratification programme, undertaken in University of Benin Teaching Hospital, with outcomes, and the actions taken to protect staff., Methods: an adapted risk stratification tool was circulated to all staff through their respective heads of departments/units. Staff were expected to voluntary assess their health and risk status in the context of COVID-19, using the tool. A central multi-disciplinary screening committee assessed submissions and invited staff who required further evaluation for physical interviews. Respondents were categorized into three risk/exposure groups from lowest to highest - A, B, and C, based on their individual health assessments, occupational exposures, and information obtained from direct interviews., Results: the committee received submissions from 746 staff, representing 19.4% (about a fifth) of the hospital's 3,840 staff. One hundred and twenty two of these were invited for physical interviews, of whom 88 (72.1%) were categorized as high risk (Category C): pregnancy (53.4%); bronchial asthma (19.3%); hypertension (11.4%); cancer (3.4%) and sickle cell disease (2.3%); fractures and pulmonary tuberculosis (1%, respectively). These staff were recommended for redeployment from areas of high risk exposure to COVID-19., Conclusion: a management-driven risk assessment of hospital staff in preparation for the COVID-19 pandemic revealed that a fifth of staff assessed themselves as being vulnerable to adverse outcomes from exposure. It is our hope that similar risk stratification programmes will become standard practice in healthcare facilities during disease outbreaks, especially in Africa., Competing Interests: The authors declare no competing interests., (©Darlington Ewaen Obaseki et al.)

Introduction: The COVID-19 pandemic presents an opportunity for the Nigerian health system to harness the potentials available in the private sector to augment the capacity within the public health system. This survey was carried out to assess private facility readiness in providing screening services in Edo State., Methods: This was a descriptive cross-sectional study carried out among private facilities in Edo state. Facilities were selected using stratified sampling technique. Data was collected using adapted questionnaires and an observational checklist. Facility readiness was assessed using the Nigeria Centre for Disease Control recommendations for screening. Parameters were scored and overall scores were converted to proportions. Facilities that scored 70% and above were adjudged to be ready while facilities that scored 69% and below were adjudged to be not ready., Results: A total of 252 health facilities were assessed, comprising 149 (59.1%) hospitals/clinics, 62 (24.6%) pharmacies and 41 (16.3%) laboratories. One hundred and forty-two (95.3%), 60 (96.8%) and 41 (100.0%) hospitals/clinics, pharmacies and laboratories, respectively had hand hygiene facilities. However, overall facility readiness assessment scores for screening services were low with only 51 (34.2%) hospitals/clinics, 2 (3.2%) pharmacies and 2 (4.9%) laboratories achieving high enough scores to be adjudged ready for screening services., Conclusion: Overall facility readiness of the private health sector to provide screening services in Edo State was assessed to be low. The government and facility owners will need to ensure that screening services are improved in all facilities to help mitigate community spread of COVID-19., Competing Interests: The authors declare no competing interests., (© Darlington Ewaen Obaseki et al.)

Objective: To determine the accuracy of a semi-quantitative interleukin-6 (IL-6) vaginal secretion rapid test (Chorioquick) for detecting chorioamnionitis in women with premature rupture of membranes (PROM)., Methods: A prospective cohort study in five tertiary hospitals in Nigeria involved women with confirmed PROM at term and preterm PROM with or without suspected chorioamnionitis from August 1, 2017, to October 31, 2018. Cervicovaginal fluid samples were tested for chorioamnionitis using the Chorioquick test. Samples were repeated at decision to deliver. The test was considered positive if at least the indicator 'IL-6 low' of the three Chorioquick biomarkers (low, medium, high) was positive, or negative if none of the biomarkers were positive. Chorioamnionitis was histologically confirmed post-delivery using three tissue samples. Primary outcome measures were sensitivity, specificity, and accuracy., Results: Of 73 women, on histological confirmation, 39 were true positive and 29 were true negative (for chorioamnionitis) to the Chorioquick test at repeat assessment. Overall, the Chorioquick test had a sensitivity of 97.5% (95% confidence interval [CI] 85.3-99.9), specificity 87.9% (70.9-96.0), and accuracy 93.2% (79.5-99.1). Sub-group analysis of women <37 weeks of pregnancy showed a sensitivity of 100.0% (95% CI 83.4-100.0), specificity of 91.3% (70.5-98.5), and accuracy of 95.8% (82.5-99.5). Triple positive samples were 100.0% specific in all gestations., Conclusion: Chorioquick showed favorable utility for detecting chorioamnionitis in PROM and could be a reliable, non-invasive rapid tool in a real-world clinical setting., (© 2020 International Federation of Gynecology and Obstetrics.)

Morbid anatomy, University of Nigeria Teaching Hospital (UNTH) caters for over 30 million people, mainly Black Africans. Sixty oral and jaw specimens were received and analyzed. In UNTH, Nigeria record of incidence and pattern of salivary lesions is scanty and, there had been no prior published report on this subject. This is a retrospective study to establish the pattern of oral and jaw tumours seen in Eastern Nigeria and show their sex and age variations. 2. Compare with results published elsewhere. Departmental records for oral and jaw lesions from biopsies were analysed. Sixty oral and jaw tumours were received out of a total of 4500 specimens constituting 1.3% of all biopsies. Twenty-four (40%) were males, 36 (60%) were females. The categories were calcifying odontogenic cysts and fibromas 11 (18.3%). Ameloblastomas affecting the mandible eight (13.3%). Fibrous dysplasia seven (11.7%). Invasive squamous cell carcinomas seven (11.7%). Infections with cellulites and sinusitis six (10%). Post inflammatory polyps and pseudocysts four (7%). Burkitt's Lymphomas four (7%), Haemangiomas and lymphangiomas four (7%), Soft tissue swellings from osteomyelitis three (5%). Butyroid rhabdomyosarcoma, adenoid cystic carcinoma angiofibroma, fibrous histiocytoma and fibrosarcoma were each one (1.7%). Oral and jaw tumours therefore constitute a mere 1.3% of biopsies. The most common subtype seen were the dentigerous cysts/fibromas, followed by ameloblastomas.
