Item The extent of the role of apoptosis in oral lichen planus – a morphometric study(University of the Western Cape, 2016) Zwet, Marwa; Hille, Jos; Adeola, HenryOral lichen planus (OLP) is a T-cell mediated chronic inflammatory disease with different clinical types that remains inscrutable in respect of its pathogenetic mechanisms and effective therapy. Increased apoptosis may influence the histopathological criteria of oral lichen planus (decrease in thickness of the epithelium and band of inflammatory infiltrate). Null hypothesis: The apoptotic rate does not correlate with a decrease in the epithelial thickness as well as the thickness of the band of inflammatory infiltrate in OLP. Aim: The present study aims to quantify apoptotic activity and to correlate the apoptotic rate with epithelial thickness as well as thickness of the inflammatory infiltrate of OLP cases diagnosed at Tygerberg Hospital from 2006 – 2015. Further, the epithelial thickness and thickness of the inflammatory infiltrate were also assessed for their association, if any. Materials and Methods: The study sample comprised 17 diagnostically verified cases of OLP. Sections stained with Haematoxylin and Eosin (H&E) were used to identify and count the number of apoptotic cells as well as measure the thickness of epithelium and the thickness of the lymphocytic inflammatory infiltrate by using software morphometric analysis (Zen Blue lite 2012). Statistical analysis was applied to analyse the correlation between apoptotic cells and histopathological features of OLP. Results: The present study's results showed no statistically significant association between the apoptotic rate, the epithelial thickness and the thickness of the lymphocytic inflammatory infiltrate.Item Prevalence and distribution of HPV infection and subtypes in oral squamous cell carcinoma in Africa: A systematic review protocol(BMJ Publishing Group, 2021) Holmes, Haly Karen; Afrogeh, Amir; Adeola, HenryHuman papillomavirus (HPV) is an established risk factor for oropharyngeal squamous cell carcinoma, regardless of a history of other known risk factors such as alcohol and tobacco. While cases of HPV-related oral squamous cell carcinoma (OSCC) are increasing in the USA, Europe and South Central Asian countries, little is known about the impact of the disease on the African continent. s We describe a protocol for a systematic review to synthesise the best current evidence to assess the disease burden in Africa.
