One of the most global health problems today is the SARS-CoV-2 coronavirus pandemic and its numerous complications. COVID-19 was first reported in China in the city of Wuhan in December 2019. It was found that coronavirus infection leads to microvascular and macrovascular complications throughout the body. Recent data indicate a strong link between severe clinical manifestations of COVID-19 and an increased risk of thromboembolism. It is associated with several risk factors such as systemic hyperinflammation caused by coronavirus infection, hypoxia, and comorbidities. The pathophysiological mechanisms underlying coagulopathy associated with COVID-19 include diffuse damage to endothelial cells, abnormal blood flow dynamics, and uncontrolled platelet activation. Studying the situation during the COVID-19 pandemic, we can notice that patients develop various complications during or after COVID-19. This article describes a clinical case of a patient with type 2 diabetes mellitus who has developed cavernous sinus thrombosis complicated by osteomyelitis of the upper jaw after COVID-19 infection.
Considerable morbidity upon spontaneous wound healing (phlegmons, osteomyelitis, and purulent osteoarthritis of metatarsophalangeal joint) as well as loss of the diseased foot's walking ability are among the reasons for transition to plastic surgery in management tactics. The longer foot lesion persists, the higher probability of amputation. Improvement of treatment of both wound and ulcer lesions by means of reconstructive surgery in patients with diabetic foot syndrome was the main aim of the study. Outcomes of treatment of 460 patients managed at the Center for the Scientific and Clinical Study of Endocrinology, within the period from 2001 to 2009 were analyzed. Size, form, depth and localization of a wound, tissue composition of the wound bed as well as circulation in skin flaps caused the choice of specific operation: autodermoplasty by Parin (with the split-thickness skin flap), local tissue plastic operation (with the sliding or inter-advancing skin flaps, flaps from previously amputated toe or Indian flaps), plastic operation with the controlled tissue tension or combined plastic operation. Reconstructive foot wound surgery allows restoring load-bearing function of the extremity much earlier in contrast to spontaneous healing, reducing incidence of post-operative and long-term complications, amputations and re-amputations, decreasing period of treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
