Cherry angioma: A case-control study.

Background: Cherry angiomas (CAs) are very common asymptomatic vascular skin lesions. There are only a few studies on CAs in the literature and those assessing risk factors of CAs are scarce. The aim of our study was to determine risk factors for the development of CAs.

Anemia, Blood Transfusion, and Filter Life Span in Critically Ill Patients Requiring Continuous Renal Replacement Therapy for Acute Kidney Injury: A Case-Control Study.

Background: Filter clotting is frequent during continuous renal replacement therapy (CRRT), which increases anemia risk. We studied anemia and blood transfusion in critically ill patients requiring CRRT for acute kidney injury and assessed the relationship between CRRT filter life span and PRBC transfusion.

Methods: A case-control study was conducted at a tertiary-care intensive care unit (ICU) where CRRT cases were matched with controls for age, gender, admission category, and severity of illness.
