Article Synopsis
- Pityriasis versicolor (PV) is a skin condition linked to Malassezia species, and this study focused on its relationship with sebum and hydration levels in adolescents in Ibadan, Nigeria.
- Higher sebum levels and lower skin hydration were observed in students with PV compared to those without.
- Malassezia globosa was identified as the most common species associated with PV, but no strong connections were found between the species and clinical features, indicating a need for further research.
Introduction: Dermoscopy has evolved over the years beyond distinguishing benign pigmented lesions from melanoma to diagnosing virtually all diseases in dermatology. Overwhelming evidence demonstrates its utility in improving diagnostic accuracy, reducing unnecessary biopsies and lesion monitoring. Dermoscopy is widely used in Western nations, hence most descriptions of lesions in literature are predominantly on Fitzpatrick skin types I-III.

- Androgenetic alopecia, or male pattern baldness, is largely influenced by genetics, but most research has focused on individuals of European descent.
- A study of 2,136 men from Ghana, Nigeria, Senegal, and South Africa found that genetic predictions for baldness based on European data were less accurate for African populations.
- The first African genome-wide association study (GWAS) identified 266 genetic associations with baldness, showing that most genetic influences are autosomal and that evolutionary history affects genetic predictions across different ancestries.
Introduction: Tracheostomy is a life-saving procedure; the benefits and frequency of procedures being performed have led to frequent reviews of indication in many regions of the world. The aim is to establish the indications, diagnosis and complications of tracheostomy performed in the past 10 years in a tertiary hospital in Lagos.
Methods: This is a 10-year retrospective study of all patients who had tracheostomies for various indications from 2010 to 2019.
Dermoscopy of Cutaneous Neoplasms in Skin of Color - A Systematic review by the International Dermoscopy Society "Imaging in Skin of Color" Task Force.
Dermatol Pract Concept
October 2023
Over the last few decades, dermoscopy has been showed to facilitate the non-invasive diagnosis of both benign and malignant skin tumors, yet literature data mainly comes from studies on light photo-types. However, there is growing evidence that skin neoplasms may benefit from dermoscopic assessment even for skin of color. This systematic literature review evaluated published data in dark-skinned patients (dermoscopic features, used setting, pathological correlation, and level of evidence of studies), also providing a standardized and homogeneous terminology for reported dermoscopic findings.
