The intrathecal drug delivery system (ITDDS), an effective treatment tool for intractable spasticity and pain, is associated with various complications but breakage of the catheter is rare. We report the case of a 50-yr-old man with ITDDS, in whom an intrathecal catheter was severed, resulting in a 28.6-cm-long intrathecal fragment. The catheter completely retracted into the intrathecal space from the anchor site. The catheter was severed during spine flexion, and the total distal fragment was repositioned in the intrathecal space. Although the outcome of ITDDS was associated with the length or diameter of the broken catheter, no neurologic complications occurred in our patient. Thus, we inserted another catheter instead of removing the old one. Thereafter, the patient has been regularly followed up, and no neurologic complications have developed during the 28 months.

This study evaluated the structure of complex regional pain syndrome (CRPS) population and suggested a weighted scoring system to balance on objective signs. One hundred sixty-eight consecutive patients were evaluated using the Budapest Research Criteria (BRC). By using multidimensional scaling and logistic regression analysis, we analyzed the degree of importance and relationships between objective findings. In addition, a receiver operating characteristic curve was constructed using a weighted score derived from the risk ratio as a diagnostic test. There were correlations between skin color change and edema, and between decreased range of motion and motor dysfunction when multidimensional scaling was applied. The trophic change was excluded by a logistic regression (95% CI; 0.80-11.850). The cutoff point based on weighted score derived from the risk ratios for determining CRPS was 7.88. At this point, the sensitivity, specificity, positive predictive value and negative predictive value were 75.0%, 95.3%, 96.3%, and 70.1%, respectively. We propose a weighted scoring system for the BRC using risk ratios of objective signs. Although a thorough systematic review would be required in the future, this study can contribute to reduction of the possible distortion of the feature of CRPS populations by the BRC.

Objective:
The purpose of this study was to analyze the current situation concerning professionalism among emergency physicians in South Korea by conducting a survey regarding their perceptions and experiences of unprofessional behavior.
Methods:
In October 2018, the authors evaluated the responses to a questionnaire administered to 548 emergency physicians at 28 university hospitals. The participants described their perceptions and experiences concerning 45 unprofessional behaviors classified into the following five categories: patient care, communication with colleagues, professionalism at work, research, and violent behavior and abusive language. Furthermore, the responses were analyzed by position (resident vs. faculty). Descriptive statistics were generated on the general characteristics of the study participants. To compare differences in responses by position and sex, the chi-square and Fisher exact tests were performed.
Results:
Of the 548 individuals invited to participate in this study, 253 responded (response rate, 46.2%). In 34 out of 45 questionnaires, more than half of participants reported having experienced unprofessional behavior despite their negative perceptions. Eleven perception questions and 38 experience questions for unprofessional behavior showed differences by position.
Conclusion
Most emergency physicians were well aware of what constituted unprofessional behavior; nevertheless, many had engaged in or observed such behavior.

We report a rare case of vascular injury secondary to a damaged Hot Shearstrade mark tip cover. Two 1 mm holes in the tip cover resulted in perforations in the obturator and external iliac veins during pelvic node dissection. Bleeding was controlled with bipolar coagulation and a 5 mm metal clip in the obturator and iliac vein, respectively. The rest of the procedure was completed uneventfully. Frequent integrity assessment of this accessory is necessary. Its function is important in order to carry out safe dissection in proximity to delicate structures. When injuries arise from areas not directly involved in the dissection, immediate inspection of the instruments should be mandatory.
