Health care workers performing aerosolizing procedures on patients with transmissible infections such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are at high-risk for disease acquisition. Current guidelines designed to protect health care workers during aerosolizing procedures prioritize personal protective equipment and enhanced infection control techniques, in particular during procedures such as intubation. To date, little emphasis has been placed on risk mitigation in the setting of bronchoscopy, a procedure that has significant aerosolization potential. Herein, we present an innovative closed bronchoscopy system designed to reduce aerosolization during bronchoscopy.

Congenital methemoglobinemia is a rare disease that is easily overlooked in its mild form. It can lead to tissue hypoxia as methemoglobin does not possess oxygen-carrying capacity. ⋯ The perioperative management of congenital methemoglobinemia is well described in the literature; however, its management in children with congenital heart disease and undergoing cardiac surgery using cardiopulmonary bypass has not been reported. We present a case and its management where congenital methemoglobinemia was detected in the operating room in a child scheduled for cardiac surgery.

We report a case of an extremely low birth weight premature infant born at 27 weeks of gestation, transferred to our tertiary pediatric referral center for surgical repair of an esophageal atresia. Endoscopic evaluation before the start of surgery revealed a hypopharyngeal perforation, resulting in the false impression of esophageal atresia. If no tracheoesophageal fistula is found during tracheoscopy, esophagoscopy should be done before surgical intervention as the inability to pass a nasogastric tube into the stomach is not sufficiently reliable for a correct diagnosis of esophageal atresia.

Case Reports
Palliative Nerve Block for Penile Calciphylaxis: A Case Report on Ultrasound-Guided Phenol Neurolysis.
A 78-year-old man with uncontrolled diabetes, heart failure, and hemodialysis-dependent end-stage renal disease presented with intractable penile pain secondary to calciphylaxis and necrosis of his glans penis. Given pain refractory to pharmacologic management and refusal of surgery, treatment entailed an ultrasound-guided dorsal penile nerve block with 5 mL of aqueous 4% phenol bilaterally. The patient reported immediate relief and died pain-free 3 months later. While phenol nerve blocks are increasingly uncommon due to local tissue toxicity, the precision of ultrasound leverages phenol's denaturing and axonal demyelinating properties to facilitate long-term targeted neurolysis to palliate chronic nonmalignant pain.

Case Reports
Potential Patent Blue V Overdose in a Patient Undergoing Free-Flap Breast Reconstruction: A Case Report.
The case of a patient who experienced serious adverse effects following a potential overdose of Patent Blue V dye (PVB) is presented here. A 65-year-old woman developed cardiac arrythmias and circulatory instability 35 minutes after receiving 100 mg PVB during breast cancer surgery. ⋯ However, mast-cell tryptase levels were normal and subsequent allergy testing for all potential allergens was negative. This case highlights that life-threatening reactions to perioperative PVB should not always be attributed to anaphylaxis; systemic toxicity could occur with an overdose.
