Mucormycosis, also known as "black fungus," is a potentially fatal disorder that causes blurred or double vision, chest pain, and breathing problems. The introduction of novel risk factors and causative agents, as well as the problems with controlling the disease, are all significant problems with mucormycosis in India. It is most common among COVID-19 patients. Mucormycosis is an invasive fungal disease that primarily affects immunosuppressant patients, mainly caused by mold fungi of the genus mucor, rhizopus, rhizomucor, and absidia, which are in the zygomycetes class and the mucorales order. The most common risk factor is diabetes mellitus, followed by haematological malignancy and solid-organ transplantation. Reversal of underlying predisposing factors, surgical debridement of infected tissues, and proper antifungal therapy are all required for the treatment of mucormycosis. In this review, the epidemiology, pathogenesis, and symptoms of black fungus and its association with covid-19, treatment and diagnosis are discussed.

: Colorectal cancer is the third most common form of cancer in the world and is a significant cause of death from cancer. To get a cure for colorectal cancer, early diagnosis and screening are necessary, as well as a clear understanding of the molecular basis of the disease. Molecular characterization of mutations associated with cancer provides useful information on the prognosis and reaction to therapy. This review discusses the clinical, molecular, and pathogenic features of the early onset of colorectal cancer, its screening tests, and diagnosis. The recent advances and rapid growth of computational tools in colorectal cancer used for diagnosis as well as screening are outlined in this review, including artificial intelligence, computer aided diagnosis, molecular docking, machine learning, and deep learning. In recent developments, the application of artificial intelligence has proved its excellency and shown a promising result, pointing out the severe need for a multidisciplinary approach to achieve an excellent result.
