Advancements in dermoscopy techniques have elucidated identifiable characteristics of melanoma which revolve around the asymmetrical constitution of melanocytic lesions consequent of unfettered proliferative growth as a malignant lesion. This study explores the applications of hierarchical density-based spatial clustering of applications with noise (HDBSCAN) in terms of the direct diagnostic implications of applying agglomerative clustering in the spectroscopic analysis of malignant melanocytic lesions and benign dermatologic spots. 100 images of benign (n = 50) and malignant moles (n = 50) were sampled from the International Skin Imaging Collaboration Archive and processed through two separate Python algorithms. The first of which deconvolutes the three-digit tupled integer identifiers of pixel color in image composition into three separate matrices corresponding to the red, green and blue color channel. Statistical characterization of integer variance was utilized to determine the optimal channel for comparative analysis between malignant and benign image groups. The second applies HDBSCAN to the matrices, identifying agglomerative clustering in the dataset. The results indicate the potential diagnostic applications of HDBSCAN analysis in fast-processing dermoscopy, as optimization of clustering parameters according to a binary search strategy produced an accuracy of 85% in the classification of malignant and benign melanocytic lesions.
Although the efficacy of water-assisted colonoscopy is well established, the role of water immersion sigmoidoscopy (WIS) remains unclear. We compared WIS with carbon dioxide insufflation sigmoidoscopy (CO2S) on patient outcomes.

We conducted an analysis of prospectively collected data from a single-center quality improvement program about patients undergoing unsedated screening sigmoidoscopy (WIS and CO2S) between May 2019 and January 2020. Outcomes studied included the following Rates of severe pain <17% (score of ≥7 on a numeric rating scale of 0-10, and on a Likert scale), willingness to repeat the procedure without sedation, adequate bowel cleanliness >75% (proportion of Boston Bowel Preparation Scale score 2-3) and adenoma detection rate (ADR).

In total, 234 patients (111 WIS; 123 CO2S) were included. All patients were aged 58 years and 58.9% were female; baseline characteristics were comparable between groups. There were no significant differences in rates of severe pain (WIS 16.5%, CO2S 13.8%; P = 0.586), willingness to repeat the unsedated procedure (WIS 82.3%, CO2S 84.5%; P = 0.713), adequate bowel cleanliness (WIS 78.4%, CO2S 78%, P = 0.999) or ADR (WIS 25.2%, CO2S 16.3%; P = 0.106) between groups. However, average procedure times were longer with WIS (9.06 min) compared to CO2S (6.45 min; P < 0.001). Overall, 29.6% of women reported that they would repeat sigmoidoscopy only if sedated.

WIS does not ameliorate tolerance to and quality of sigmoidoscopy screening measured by several scores. When offered a choice, the women's willingness to repeat WIS or CO2S without sedation was poor and raises concern on the opportunity of screening sigmoidoscopy without sedation in these subjects.

H2DCFDA We report a case of uterine fusion defect diagnosed intra-operatively in a 20-year-old primigravida who had elective caesarean section at term on account of breech presentation at term. Intraoperative findings included a cone-shaped uterus with narrowed fundus and the appendages emerging at the fundus and lower uterine segment on the right and left respectively. This is a rare fusion defect and makes a case for review of the existing uterine malformation classification systems, to make it all encompassing.
Understanding pattern and outcome of traumatic spinal cord injury (TSCI) will inform better management which expectedly would improve prognosis and minimise complications.

A retrospective study was carried out on all managed TSCI cases from January 2009 to December 2018. Sociodemographic characteristics, injury type, cause and complications were extracted from patients' registers and case folders. Descriptive statistics summarised the data, and Fisher's exact test analysed associations between variables.

Eighty-one cases met the inclusion criteria and were analysed. Most cases (91.4%) were males, aged 18-39 years (65.4%) and were civil servants (37.0%). Road traffic accident (RTA) was the leading cause of injury (37.0%) and incomplete lesion predominated (69.1%). Cases referred for physiotherapy constituted 77.8%, only 14.8% of cases recovered without neurological deficits. On discharge, most patients were wheelchair bound (33.3%). Region of spine affected showed significant association with complicatiptible and offer prompt preventive measures.
The modern arterial tourniquet is an automatic tourniquet system which contains many features that help to minimise complications and improve safety. However, the non-pneumatic tourniquet is still in use, a practice that may be commoner in resource-constrained settings. This study was conducted to investigate the types of tourniquet available and used by orthopaedic surgeons in Nigeria as well as the practical aspects and complications of their use of the tourniquet.

At an Annual General Meeting/Scientific Conference of Nigerian Orthopaedic Association, a survey was conducted among orthopaedic surgeons using a pre-tested self-administered questionnaire which contained questions on types of tourniquet, practical aspects of the use of tourniquet and complications.

The non-pneumatic tourniquet was usually used by 60.2% of the respondents and 58.1% of those who had both pneumatic and non-pneumatic tourniquets used the latter more commonly. In most cases, the tourniquet was applied by surgeons or surgical residents on the arm or thigh. Surgeons who had ever used the tourniquet in diabetic patients were 71.6% while 29.5% had used it in patients with sickle cell disease. Tourniquet duration was usually 1½ h and 2 h in the upper and lower limbs, respectively. The two most common complications were tourniquet palsy and tourniquet pain.

The non-pneumatic tourniquet was more commonly used than the pneumatic tourniquet. Application of the tourniquet on sites other than the thigh and the upper arm were uncommon. The most common complication was neurologic injury.

Existing evidence suggests that barotitis media (BM) is common among air travellers, and it has the potential to cause severe discomfort and sometimes permanent hearing and balance deficits. It has not been studied in Nigeria.

This study aimed to assess the pre-air travel health-seeking behaviour, prevalence of BM, knowledge of BM and its associated factors among a cohort of outpatients with a history of recent air travel in Kano, Nigeria.

This questionnaire-based survey involved 97 participants systematically and proportionately selected from adult patients or caregivers of children with recent air travel history attending two outpatients clinics over 7 weeks. Information on biodata, pre-air travel advice-seeking behaviours, air travel experience and BM knowledge were obtained. Data were analysed using the descriptive statistical methods, Chi-square or Fisher's exact tests and odds ratio (OR).

Most participants were male (54.6%) with tertiary education (87.6%); the prevalence of BM was 44.3% (43/97). Only 2.1% (2/97) had ever sought pre-air travel advice from a doctor; 83.5% (81/97) had heard of BM before; 42% had adequate knowledge of BM. Employment status (Fisher's exact, P = 0.001), clinic at recruitment (Fisher's exact, P = 0.00008), duration of last flight (Fisher's exact, P = 0.0001) and persistent ear-pain after landing (Fisher's exact, P = 0.001) were significantly associated with participants' knowledge of BM. Persistent ear-pain after landing was the predictor of BM knowledge (OR = 0.04, 95% confidence interval [0.002-0.67], P = 0.025).

The BM knowledge level of this cohort suggests the need for further studies to ascertain the complete picture and justify improved pretravel education of air travellers in our setting.

Waterpipe smoking (WPS) has been reported to have a wide range of damaging health effects on pulmonary and cardiovascular systems. Studies suggest that waterpipe tobacco smoking is associated with reduced harm perceptions, mental health problems and the use of psychoactive substances. We investigate the patterns of use and the association of WPS with anxiety, poly-tobacco and alcohol use in Lagos, Nigeria.

A cross-sectional study design was used to assess the data from 818 adolescents and adults in Lagos State, Nigeria. An online questionnaire obtained demographic information, waterpipe, e-cigarette, alcohol and other tobacco product use from respondents. Anxiety was assessed using the validated Generalised Anxiety Disorder 7-point scale. Bivariate and multivariate logistic regression analysis was used to identify the factors associated with waterpipe ever-use. P < 0.05 was considered statistically significant.

The mean (standard deviation) age of respondents was 23.43 (±3.96), over half were female WPS and a more comprehensive smoke-free policy.
Our findings suggest a relatively high prevalence of WPS in Lagos, Nigeria. Concurrent alcohol consumption, e-cigarette and poly-tobacco use are associated with WPS, and most waterpipe smokers have normal anxiety levels. The Nigerian Government should consider surveillance measures for WPS and a more comprehensive smoke-free policy.
With the advent of endoscopic sinus surgery, the variant neurovascular relations of the sphenoid sinus are important to surgeons to minimise the iatrogenic complications. This study elucidates the variant neurovascular relations of the sphenoid sinus in adult Nigerians.

This study was conducted at the Radiology Department of Delta State University Teaching Hospital after institutional approval. Brain computed tomography images of 336 patients, aged ≥20 years and spanning over 5 years' duration were utilised. We evaluated the sphenoid sinus for protrusion and dehiscence of neurovascular structures bilaterally. The position of the optic nerve in relation to the sinus was classified from Type 0-4. The Statistical Package for the Social Sciences software version 23 was used for the data analysis. The Chi-square test was used to probe for the association between the variants with regard to side and gender. P < 0.05 was considered statistically significant.

Dehiscence and protrusion of the internal carotid artery (ICA) occurred in 34, 10.
