[Insulinoma and pregnancy: anesthesia and perioperative management].

Unlabelled: Insulinoma is a functional neuroendocrine tumor derived from beta cells of the pancreatic islets of Langerhans, usually solitary, benign, and curable with surgery (enucleation). It rarely occurs during pregnancy and is clinically manifested by hypoglycemia, particularly in the first trimester of pregnancy. During pregnancy, both conservative therapeutic measures (medication) and surgical treatment are challenging regarding the impossibility of studies on drug teratogenicity as well as the maternal-fetal repercussions during surgery, such as hypoglycemia and changes due to stress.

The incidence of residual pneumothorax after video-assisted sympathectomy with and without pleural drainage and its effect on postoperative pain.

Objective: To determine the incidence of residual pneumothorax after video-assisted thoracic sympathectomy, with and without postoperative pleural drainage, and to evaluate the possible influence of this type of pneumothorax on postoperative pain within the first 28 postoperative days.

Methods: All patients presenting symptoms consistent with primary palmoplantar hyperhidrosis and treated at the Thoracic Surgery Outpatient Clinic of the State Hospital of Sumaré between July and December of 2006 were included. All were submitted to sympathectomy up to the third ganglion using video-assisted thoracoscopy and were randomized to receive or not receive postoperative pleural drainage for 3 h.
