Abstract:
Haemophilia A is a rare haematological disorder due to deficiency of Factor VIII, causing an abnormal coagulation response to injury. In severe haemophilia A, Factor VIII level is < 1%, often manifesting with spontaneous bleeding into joints. Judicious use of recombinant Factor VIII therapy to maintain adequate levels in the intraoperative, immediate and late post-operative periods, together with adjuvant pro-coagulants, can ensure a safe outcome following surgery. We describe the successful management of one such patient suffering from Marjolin's ulcer of the right gluteal region, who needed wide local excision followed by flap cover. A protocol for management of such patients is also suggested. This is the first such case report from the Indian subcontinent, with only a few such published reports from the West.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
