Prostate cancer perspective: Africa versus the world.

Prostate cancer (PCa) is one of the most commonly diagnosed cancers among men, with a rising global incidence. Currently, the PCa landscape is vastly different between developed countries and Africa. Of note, owing to various biological, socioeconomic and institutional factors, black African men often present with more advanced disease and suffer greater mortality.

A 20-year audit of the outcomes of stenting with the Montgomery Safe-T-Tube at a tertiary hospital in South Africa.

Objective: This study aimed to describe the epidemiology of laryngotracheal stenosis within a resource-constrained setting, whilst exploring the outcome correlates unique to Montgomery Safe-T-Tube stented laryngotracheoplasty.

Methods: A retrospective cross-sectional study of patients who underwent Montgomery Safe-T-Tube stented laryngotracheoplasty between January 2000 and December 2019 was performed.

Results: Amongst 75 patients, most lesions were iatrogenic (78.

Neural networks for mining the associations between diseases and symptoms in clinical notes.

There are challenges for analyzing the narrative clinical notes in Electronic Health Records (EHRs) because of their unstructured nature. Mining the associations between the clinical concepts within the clinical notes can support physicians in making decisions, and provide researchers evidence about disease development and treatment. In this paper, in order to model and analyze disease and symptom relationships in the clinical notes, we present a concept association mining framework that is based on word embedding learned through neural networks.

Giant maxillary gingival fibromatosis.

We present a case of both unusual pathology and severity - giant maxillary gingival fibromatosis - and discuss the disease and its management, accompanied by clinical imaging. This represents an overlap between maxillofacial and oral surgery, and may present as demonstrated in this case.
