Management of Renal Angiomyolipomas in Tuberous Sclerosis: A Case Series.

Renal angiomyolipomas, benign tumors composed of blood vessels, adipose tissue, and smooth muscle, affect approximately 70% to 80% of patients with tuberous sclerosis. Angiomyolipomas smaller than 4 cm are usually asymptomatic, whereas larger ones can cause lumbar pain, anemia, and hematuria. Contrary to its sporadic counterparts, tuberous sclerosis-associated angiomyolipomas often present at a young age, are multicentric and large, and carry a higher risk of life-threatening hemorrhage.

Preoperative STOP-BANG questionnaire to predict difficult airway in undiagnosed obstructive sleep apnea patients undergoing elective gynecological surgeries under general endotracheal anesthesia: A prospective observational study.

Background: STOP-BANG questionnaire is an established tool for obstructive sleep apnea (OSA) screening. Its utility in predicting difficult airway has not been evaluated. We intend to assess difficulty in airway management and associated perioperative complications in patients with undiagnosed OSA using the STOP-BANG questionnaire.
