COVID-19-associated mucormycosis of head-and-neck region: A systematic review.

Background And Aim: With the second wave of COVID-19, there has been a substantial rise in opportunistic infections like mucormycosis. Mucormycosis is a fatal fungal infection and understanding the associated risk factors and their management plays a key role to reduce mortality and morbidity caused due to such infections. This systematic review was conducted to assess the risk factors, clinical characteristics and to understand the pathogenesis of COVID-19-associated mucormycosis (CAM) affecting the head-and-neck region.

A Rare Case of Tamarind Seed Induced Oral Submucous Fibrosis in a 12-Year-Old Indian Boy.

Oral Submucous Fibrosis (OSMF) is a chronic debilitating, potentially malignant disorder of the oral cavity. It is characterized by restricted mouth opening which results due to abnormal accumulation of collagen in the sub-epithelial layers leading to dense fibrous bands in the mouth. The pathogenesis of the disease is believed to be multifactorial.

Quantification and Correlation of Angiogenesis with Macrophages by Histomorphometric Method in Central and Peripheral Giant Cell Granuloma: An Immunohistochemical Analysis.

Introduction: Angiogenesis is a fundamental process that affects physiologic reactions and pathological processes such as tumour development and metastasis. It is the process of formation of new microvessel from the preexisting vessels.

Aim: The purpose of this study was to evaluate angiogenesis, macrophage index and correlate the impact of macrophages on angiogenesis in the central and peripheral giant cell granulomas by evaluating immunohistochemically microvessel density, microvessel perimeter and macrophage index.
