Since its introduction, Bentall procedure has remained the standard of care for management of ascending aortic aneurysms with associated aortic valve pathologies. It involves replacement of aortic root, ascending aorta and the aortic valve, using a hybrid vascular graft with built in valves. The openings of the main coronary arteries are then rejoined with the graft. The procedure has satisfactory long term survival rate. However, there are some complications including graft infection, stroke from dislodged plaques and coronary insufficiency due to kinking of the reconnected main coronary arteries.
Here, we report a rare and life-threatening complication following Bentall procedure. A 76-year-old female developed left main stenosis following Bentall procedure, successfully treated with percutaneous coronary intervention (PCI). We discuss various etiologies and treatment options for this complication. We recommend routine surveillance with coronary angiography at six months post Bentall.
While the presence of metastatic melanocytoma in the central nervous system (CNS) is relatively common, primary spinal melanocytoma (PSM) is an extremely rare entity. Only 70 cases have been reported, and its usual position is the cervical region. We report a case of a 35-year-old male with primary spinal intramedullary melanocytoma with a dorsal exophytic component. The tumor was first opened in the periphery and was closed without being operated upon due to it being an uncommon pathology.
COVID-19 has rampaged across continents and has caused a devastating impact on life, economy, mobility, and health. Vaccines are still under clinical trials however there is no immediate solution or drug at hand for effective treatment. During this time, finding an unorthodox solution has become the need of the hour. Nigella sativa, commonly known as the black seed has been widely used as a traditional medicine in the past to fight illnesses. Chief compounds of N. Sativa seed, especially thymiquinone, α‐hederin, and nigellidine, could be developed into promising herbal drugs to combat COVID‐19 due to their therapeutic benefits. Extensive studies on N. Sativa have demonstrated its wide spectrum pharmacological properties which include immunomodulatory, analgesic, anti-inflammatory, antiviral, bronchodilatory, hepato-protective, reno-protective, gastro-protective, and antioxidant properties that can serve as a potent inhibitor for SARS-CoV-2. Furthermore, N. Sativa has also exhibited antidiabetic, antihypertensive, and antibacterial properties which would help COVID-19 patients with comorbidities. The objective of this review is aimed at establishing a link between the pharmacological benefits of N. Sativa and its potential to serve as a cure for COVID-19.
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.
