A Double-Blind, Placebo-Controlled Study of Ultrasound-Guided Pulsed Radiofrequency Treatment of the Saphenous Nerve for Refractory Osteoarthritis-Associated Knee Pain.

Background: While the efficacy of pulsed radiofrequency (PRF) for shoulder pain has been demonstrated, its efficacy on the saphenous nerves for knee osteoarthritis (OA)-associated pain has only been reported in observational studies.

Objectives: The aim of this study was to compare saphenous nerve PRF to placebo for knee OA-associated pain.

Study Design: Patients, practitioners, and outcome assessor-blinded randomized placebo-controlled trial.

Bromocriptine use for sudden peripartum cardiomyopathy in a patient with preeclampsia: a case report.

Background: Peripartum cardiomyopathy is an uncommon form of heart failure that occurs in otherwise healthy women during pregnancy or until 5 months postpartum. Here, we report a rare case where a female patient underwent cesarean section after the occurrence of preeclampsia and intrauterine fetal death, and developed peripartum cardiomyopathy following postsurgical respiratory distress. The prompt initiation of inotropic drug and bromocriptine therapy quickly restored cardiac function.

An analysis of the factors influencing pulmonary artery catheter placement in anesthetized patients.

Background: Pulmonary artery catheters are usually placed by resident anesthesiologists with pressure wave monitoring from educational point of view. In some cases, the placement needs longer time or is difficult only by observing the pressure waves.

Aims: We sought to examine the time required for the catheter placement in adult patients and determine factors influencing the placement.

[Waldenström macroglobulinemia complicated with chylothorax].

An 81-year-old male had been diagnosed with Waldenström macroglobulinemia (WM) eight years previously and had thus been administered appropriate treatment. Left chylothorax later developed at 3 years and 8 months after the initial diagnosis. He was hospitalized with severe anemia, general fatigue, and appetite loss one year prior to this presentation and died due to a severe fungal infection.
