Colorectal cancer (CRC) is the most prevalent gastrointestinal (GI) cancer. With 5% risk of developing CRC in life, it became the third leading cause of cancer death in developed nations. In Nigeria, it is the most common GI cancer. However, there are limited data on CRC in the study area (North-Western part of Nigeria). The aim of this study was to identify the clinical, endoscopic and histological profile of CRC seen on colonoscopy.

This was a retrospective descriptive study where colonoscopic and histological records of suspected CRC in the study centre between January 2008 to December 2017 were evaluated.

Records of 135 patients were reviewed, and males constituted 63.7%. The mean age was 46.61 ± 16.80 years, with 30-39 years as a modal group. Common presentations were diarrhoea (86.7%) and bleeding per rectum (68.9%). Areas affected were rectosigmoid colon (63%), ascending colon (14.1%), descending colon (8.9%), transverse colon (7.4%) and anal canal (6.7%). Histologically, adenocarcinoma was reported in 57.8%, mucinous adenocarcinoma in 8.1% and signet ring cell adenocarcinoma in 3.7%. Tubular and villous adenomas were 3% each. Others were carcinoid tumours (1.5%), metastatic adenocarcinoma, squamous cell carcinoma, basal cell carcinoma, GI stromal tumour, inflammatory myofibroblastic tumour, angiosarcoma and adenoid cyst carcinoma reported in 0.7% each.

Majority of the patients with CRC were in their young age. The most common presentations were diarrhoea, weight loss and anaemia. The most common site of affectation was in the left colon, while the most common histological finding was adenocarcinoma.

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.

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.

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. sirpiglenastat 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.

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.

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.

Volunteering within the health-care sector is crucial during pandemics. This study aimed to assess the attitudes and perceptions of clinical medical and dental students in Lagos, Nigeria, about volunteering during the coronavirus disease 2019 (COVID-19) pandemic.

A descriptive cross-sectional study was conducted amongst medical and dental students undergoing clinical postings at the two public universities in Lagos, Nigeria, using total population sampling. Data were collected using a web-based questionnaire and analysed using Statistical Package for the Social Sciences. Chi-square test and logistic regression analysis were used to test for association at the level of significance of 5%.

The mean age of the respondents was 23.3 years ± 2.6 standard deviation and 62.5% were females. The majority (82.9%) of the respondents agreed to volunteer if provided with adequate personal protective equipment (PPE) and if adequately trained to do so (79.3%). Although perceived as dangerous, the majority (91.2%) of the respondents considered volunteering during the COVID-19 pandemic as a form of educational experience. Compared to the final-year students, penultimate year students were more likely to volunteer in the event of a health manpower shortage. The final-year students were more likely to volunteer if government made the request. Female students were more likely than male students to volunteer even if they were not compensated but would require parental approval.

Medical and dental students perceived their involvement during the COVID-19 pandemic as a form of educational experience but would require adequate training and PPE. There is a need to train and provide adequate PPE for them to function as volunteers.

We present a case of a 7-year-old male child who presented to us with gradually progressive spastic quadriparesis following a fall from table. His lateral radiograph and magnetic resonance images showed mobile atlantoaxial dislocation with intramedullary heterogeneously enhancing cervicomedullary mass. The patient underwent suboccipital craniectomy with C1-4 laminectomy. Tumor was pinkish grey, tenacious with ill-defined plane and cyst at poles. C1-C2 fusion was done using C1 lateral mass and C2 pars screw and rod system with onlay bone graft. Histopathology revealed pilocytic astrocytoma. At the time of discharge, the patient showed improvement in spasticity. Postoperative lateral radiograph showed reduced atlantoaxial dislocation with stable construct.
