Prognostic Factors in Complex Regional Pain Syndrome Type 1 Occurring in the Korean Army.

Objectives: In Korea, patients diagnosed with complex regional pain syndrome (CRPS) in the army are typically discharged from the army; however, the course of the disease after discharge is not known. The purpose of this study was to investigate the course of CRPS that occurred in the army and to identify the influences of various clinical and psychosocial factors immediately before discharge on the disease course.

Methods: Clinical profiles and psychosocial status were collected from the medical records of 16 patients with CRPS type 1 who were discharged during the period between March 2017 and April 2018.

A Randomized Controlled Trial about the Levels of Radiation Exposure Depends on the Use of Collimation C-arm Fluoroscopic-guided Medial Branch Block.

Background: C-arm fluoroscope has been widely used to promote more effective pain management; however, unwanted radiation exposure for operators is inevitable. We prospectively investigated the differences in radiation exposure related to collimation in Medial Branch Block (MBB).

Methods: This study was a randomized controlled trial of 62 MBBs at L3, 4 and 5.

The Survey about the Degree of Damage of Radiation-Protective Shields in Operation Room.

Background: Medical doctors who perform C-arm fluoroscopy-guided procedures are exposed to X-ray radiation. Therefore, radiation-protective shields are recommended to protect these doctors from radiation. For the past several years, these protective shields have sometimes been used without regular inspection.

Radiation Exposure of the Hand and Chest during C-arm Fluoroscopy-Guided Procedures.

Background: The C-arm fluoroscope is an essential tool for the intervention of pain. The aim of this study was to investigate the radiation exposure experienced by the hand and chest of pain physicians during C-arm fluoroscopy-guided procedures.

Methods: This is a prospective study about radiation exposure to physicians during transforaminal epidural steroid injection (TFESI) and medial branch block (MBB).

Growth suppression of four cancer cells by hyperbaric nitrous oxide and methotrexate.

Background: Nitrous oxide concentration is easily controlled by respiratory ventilation. It suppresses bone marrow via the inhibition of thymidylate synthesis. The aim of this work was to determine the optimal pressure and exposure duration of nitrous oxide, as well as methotrexate concentration that maximizes the suppression of 4 cancer cells: CCRF-CEM, K562, A549 and MDA-MB-231.

Does skin temperature difference as measured by infrared thermography within 6 months of acute herpes zoster infection correlate with pain level?

Background: Changes in the temperature distribution of the skin follows herpes zoster (HZ). Infrared thermography is a non-invasive, non-ionizing diagnostic tool that provides information about normal and abnormal functioning of the sensory and sympathetic nervous systems. This study examined the usefulness of infrared thermography as a predictor of post-herpetic neuralgia (PHN).

Effect of midazolam premedication on the onset of propofol and rocuronium during propofol target-controlled infusion.

Background: This clinical study was designed to evaluate the effect of midazolam as a premedication on the onset of propofol and rocuronium during propofol target-controlled infusion (TCI).

Methods: Seventy four patients (ASA class I or II) were randomly allocated to receive either no premedication (control group) or premedication with 0.04 mg/kg intravenous midazolam (midazolam group).
