Opioid Prescribing Practices Among Plastic Surgeons: Results of the 2019 American Society of Plastic Surgeons Opioid Survey.

Background: Health care providers play an important role in the national opioid crisis with 40% of opioid-related deaths being attributed to prescription medications (Centers for Disease Control and Prevention, U.S. Department of Health and Human Services.

Management of T-cell large granular lymphocyte leukemia and concurrent retroperitoneal liposarcoma.

T-cell large granular leukemia (T-LGL) is a rare lymphoproliferative disorder characterized by the clonal expansion of cytotoxic T lymphocytes. We present a unique case of T-LGL and concurrent retroperitoneal sarcoma occurring in a patient with long-standing rheumatoid arthritis. Pathology revealed a high-grade dedifferentiated liposarcoma.

Limb salvage and reconstruction following a zebra attack.

Animal bites are fairly rare events but can cause devastating traumatic injuries to the victim. In addition to the soft tissue, vascular, and orthopedic trauma inflicted by these occurrences, bite injuries also have the potential to introduce an inoculum of microbes, which may progress to an infection if not treated properly and expeditiously. We present the case of a healthy male who sustained multiple bite wounds from a domestic zebra to his left upper extremity.

Phyllodes tumor masquerading as a fungating breast mass.

Phyllodes tumor of the breast is an uncommonly encountered disease. The tumor presenting as fungating breast mass or 'ruptured' breast is an even more rare presentation of an unusual disease. This report documents the case of a 60-year-old female with delayed presentation of a large exophytic mass of the left breast.

Depressed baroreflex sensitivity in patients with obstructive sleep apnea.

Muscle nerve sympathetic activity (MSA), the interval between two R-waves in the ECG, or the interbeat interval (RR-interval), and blood pressure (BP) were recorded in 10 awake patients with obstructive sleep apnea (OSA) and in nine sex- and age-matched controls. Changes in RR-interval and MSA, evoked by sodium nitroprusside-induced reduction of BP, were used to quantitate baroreflex sensitivity. Both the cardiac (expressed as the RR-interval versus mean arterial BP slope) and the muscle sympathetic (mean MSA area versus diastolic BP slope) baroreflex sensitivity were depressed in patients as compared with controls.

Attenuated endothelium-dependent vascular relaxation in patients with sleep apnoea.

Objective: To evaluate endothelium-dependent vascular function in obstructive sleep apnoea patients.

Design And Methods: Forearm blood flow and vascular resistance were studied in eight normotensives and eight obstructive sleep apnoea patients and also in eight normotensive and eight hypertensive controls after graded brachial artery infusion of acetylcholine (10-60 micrograms/min) and sodium nitroprusside (1-6 micrograms/min), respectively. Patients and controls were matched for age, sex and body weight.

Platelet function and fibrinolytic activity in hypertensive and normotensive sleep apnea patients.

Platelet function and fibrinolytic activity was studied during rest and after ergometric exercise in 13 hypertensive or normotensive patients with obstructive sleep apnea (OSA) and in 10 sex- and weight-matched controls. All patients had undergone a complete polysomnography for the diagnosis of OSA. The controls did not undergo any sleep investigation but had no history of snoring or witnessed apneas during sleep.

High prevalence of hypertension in sleep apnea patients independent of obesity.

The relative influence of body mass index (BMI) and sleep apnea (SA) on blood pressure and prevalence of hypertension was investigated in 377 consecutive subjects admitted to a sleep laboratory. Among patients, 124 (33%) had SA, 153 (41%) were obese, and 93 (25%) had systemic hypertension. Both oxygen desaturation (OD) and minimal oxygen saturation (SaO2min) were related to BMI (p < 0.

Augmented resting sympathetic activity in awake patients with obstructive sleep apnea.

Muscle nerve sympathetic activity (MSA) was recorded during wakefulness in 11 patients with obstructive sleep apnea (OSA) and in 9 sex- and age-matched healthy control subjects. Plasma levels of norepinephrine (NE) and neuropeptide Y were analyzed. Five patients had established hypertension (resting supine systolic BP/diastolic BP > or = 160/95 mm Hg).

Secondary polycythaemia associated with nocturnal apnoea--a relationship not mediated by erythropoietin?

A polysomnographic study was undertaken in nine patients with unexplained polycythaemia and nine age- and sex-matched controls. Circulating plasma levels of immunoreactive erythropoietin (IrEPO) were analysed before and after sleep. Seven out of nine polycythaemia patients were found to have sleep-disordered breathing and fulfilled the criteria for the sleep apnoea syndrome.

Nuclear transplantation in Bombina orientalis and utilization of the Pale mutation as a nuclear marker.

The discoglossid frog, Bombina orientalis, displays many characteristics that make it desirable as a laboratory animal. We report here the first successful transplantation of embryonic nuclei into enucleated eggs of this organism. The participation of the grafted nucleus in the development of the transplant embryos was confirmed with the use of a genetic marker, the Pale mutation.
