Suspected Pseudocholinesterase Deficiency During Left Thyroid Lobectomy and Isthmusectomy: A Case Report.

Background: Pseudocholinesterase (butyrylcholinesterase) deficiency is an acquired or inherited condition in which decreased plasma levels of the pseudocholinesterase enzyme lead to an inability to metabolize the neuromuscular blocking agents succinylcholine and mivacurium, prolonging their paralytic effects. This often results in delayed extubation and additional intensive care requirements in the postoperative period.

Case Description: We describe a case of suspected pseudocholinesterase deficiency in a previously healthy 59-year-old female who underwent a left thyroid lobectomy and isthmusectomy.

Local Anesthetic Systemic Toxicity During Transversus Abdominis Plane Block With Liposomal Bupivacaine.

Local anesthetic systemic toxicity (LAST) is a rare but potentially fatal outcome associated with local anesthetic administration. Liposomal bupivacaine (LB; EXPAREL®) is a widely used local anesthetic with extended-release and liposomal formulation that carries an improved cardiac and central nervous system safety profile. However, there is limited data regarding LAST associated with liposomal bupivacaine.

Tumoral pseudoangiomatous stromal hyperplasia of the breast.

Tumoral pseudoangiomatous stromal hyperplasia (PASH) is a rare benign proliferative disease of the breast. The majority of the literature reports of PASH have not contained detailed descriptions of the imaging characteristics of PASH. A 10-year retrospective study of patients with tumoral PASH and a 20-year Ovid MEDLINE search were performed to determine whether specific imaging and needle biopsy results could characterize PASH preoperatively.
