BACKGROUND: A leukoreduction filter was recently developed in Korea to reduce various kinds of adverse transfusion reactions. The objective of this study was to propose a domestic evaluation system for leukoreduction filters and to apply this evaluation system to assess the newly developed leukoreduction filter. METHODS: We prepared packed red blood cells from 60 units of whole blood (400 mL) collected from 60 normal individuals and evaluated the efficacy of the newly developed filter (FINECELL, KOLON INDUSTRIES, Gumi, Korea) and a control filter (RCM1, Haemonetics, MA, USA). To verify the evaluation system, we assessed the filtration time, residual leukocyte count, RBC recovery, RBC hemolysis, hemoglobin concentration, and hematocrit using a control filter RCM1 and compared the results with those of an evaluation performed by the American Red Cross (ARC) in 2013. We then evaluated the efficacy of the test filter FINECELL using the methods established in this study and compared the results with those of the control filter RCM1. RESULTS: The results of the current study were similar to those of the ARC with the control filters. The test filters developed in Korea were not inferior to commonly used control filters regarding residual leukocyte count, RBC recovery, and RBC hemolysis at 35 days after filtration. All of the results in the evaluation satisfied the international standards. CONCLUSION: These results of this study showed that the efficacy of the newly developed domestic leukoreduction filter were satisfactory and will contribute to improvement of quality of blood components in Korea.

Segmental fractures of the clavicle are very rare. Therefore, to date, there has not been a clear, standardized method of management of segmental clavicle fractures. Herein, two patients with a segmental fracture are described: One patient was treated conservatively, while another patient was treated operatively. Both patients showed excellent results. We discuss the various management options with a literature review.

PURPOSE: To report the clinical results from surgical treatment for clavicle shaft fracture by percutaneous intramedullary fixation with Steinmann pins. MATERIALS AND METHODS: Between January 2004 and June 2014, the medical records of 135 patients who underwent percutaneous intramedullary fixation with Steinmann pins were reviewed. The mean follow-up periods were 15 months. The functional results were evaluated with The Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant score. The clinical results were evaluated with the shortened length of the clavicle, length of surgical wound, operation time and Kang's criteria. RESULTS: The mean bone union period was 11.6 weeks (8–16 weeks). The mean DASH score was 11.8. The mean Constant score was 91.2. The mean shortened length of the clavicle was less than 20 mm. The mean length of surgical wound was 1.2 cm (0.7–1.5 cm). The mean operation time was 18 minutes (10–35 minutes). Using Kang's criteria, 131 out of 135 patients (97.0%) showed good results. Complications included were 3 pin migrations and 2 non-unions. CONCLUSION: Percutaneous intramedullary fixation with Steinmann pins showed good results for treating clavicle shaft fracture.

OBJECTIVE: The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting. METHODS: We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study. We investigated the discontinuation rate and the mean time to discontinuation among six antidepressants groups. RESULTS: Mean and median overall discontinuation times were 13.8 and 12 weeks, respectively. Sertraline and escitalopram had longer discontinuation times than that of fluoxetine, and patients who used sertraline discontinued use significantly later than those taking mirtazapine. No differences in discontinuation rate were observed after 24 weeks among these antidepressants. About 73% of patients discontinued antidepressant treatment after 24 weeks. CONCLUSION: Sertraline and escitalopram tended to have longer mean times to discontinuation, although no difference in discontinuation rate was detected between antidepressants after 24 weeks. About three-quarters of patients discontinued antidepressant maintenance therapy after 24 weeks.

For two months between May and July 2015, a nationwide outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) occurred in Korea. On June 3, 2015, the Korean Society for Laboratory Medicine (KSLM) launched a MERS-CoV Laboratory Response Task Force (LR-TF) to facilitate clinical laboratories to set up the diagnosis of MERS-CoV infection. Based on the WHO interim recommendations, the Centers for Disease Control and Prevention of United States guidelines for MERS-CoV laboratory testing, and other available resources, the KSLM MERS-CoV LR-TF provided the first version of the laboratory practice guidelines for the molecular diagnosis of MERS-CoV to the clinical laboratories on June 12, 2015. The guidelines described here are an updated version that includes case definition, indications for testing, specimen type and protocols for specimen collection, specimen packing and transport, specimen handling and nucleic acid extraction, molecular detection of MERS-CoV, interpretation of results and reporting, and laboratory safety. The KSLM guidelines mainly focus on the molecular diagnosis of MERS-CoV, reflecting the unique situation in Korea and the state of knowledge at the time of publication.

BACKGROUND: It is crucial to understand the current status of clinical laboratory practices for the largest outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) infections in the Republic of Korea to be well prepared for future emerging infectious diseases. METHODS: We conducted a survey of 49 clinical laboratories in medical institutions and referral medical laboratories. A short questionnaire to survey clinical laboratory practices relating to MERS-CoV diagnostic testing was sent by email to the directors and clinical pathologists in charge of the clinical laboratories performing MERS-CoV testing. The survey focused on testing volume, reporting of results, resources, and laboratory safety. RESULTS: A total of 40 clinical laboratories responded to the survey. A total of 27,009 MERS-CoV real-time reverse transcription PCR (rRT-PCR) tests were performed. Most of the specimens were sputum (73.5%). The median turnaround time (TAT) was 5.29 hr (first and third quartile, 4.11 and 7.48 hr) in 26 medical institutions. The median TAT of more than a half of the laboratories (57.7%) was less than 6 hr. Many laboratories were able to perform tests throughout the whole week. Laboratory biosafety preparedness included class II biosafety cabinets (100%); separated pre-PCR, PCR, and post-PCR rooms (88.6%); negative pressure pretreatment rooms (48.6%); and negative pressure sputum collection rooms (20.0%). CONCLUSIONS: Clinical laboratories were able to quickly expand their diagnostic capacity in response to the 2015 MERS-CoV outbreak. Our results show that clinical laboratories play an important role in the maintenance and enhancement of laboratory response in preparation for future emerging infections.

BACKGROUND AND OBJECTIVES: Numbness on the hand occurs infrequently after a transradial cardiac catheterization (TRC). The symptom resembles that of neuropathy. We, therefore, investigated the prevalence, the predicting factors and the presence of neurological abnormalities of numbness, using a nerve conduction study (NCS). SUBJECTS AND METHODS: From April to December 2013, all patients who underwent a TRC were prospectively enrolled. From among these, the patients who experienced numbness on the ipsilateral hand were instructed to describe their symptoms using a visual analogue scale; subsequently, NCSs were performed on these patients. RESULTS: Of the total 479 patients in the study sample, numbness occurred in nine (1.8%) following the procedure. The NCS was performed for eight out of the nine patients, four (50%) of which had an abnormal NCS result at the superficial radial nerve. A larger sheath and history of myocardial infarction (p=0.14 and 0.08 respectively) tended towards the occurrence of numbness; however, only the use of size 7 French sheaths was an independent predictor for the occurrence of numbness (odds ratio: 5.50, 95% confidence interval: 1.06-28.58, p=0.042). The symptoms disappeared for all patients but one, within four months. CONCLUSION: A transient injury of the superficial radial nerve could be one reason for numbness after a TRC. A large sheath size was an independent predictor of numbness; therefore, large sized sheaths should be used with caution when performing a TRC.

The recent outbreak of Middle East respiratory syndrome (MERS) in Korea was unexpected that laboratory response had to be built up urgently during the outbreak. The outbreak was almost all healthcare-associated, which was aggravated by lack of availability in laboratory diagnosis of MERS-CoV on site. On behalf of the MERS joint public and private sector response committee (MERS Joint committee), the Korean Society for Laboratory Medicine (KSLM) launched a MERS response task force (MERS KSLM TF) to facilitate clinical laboratories set up MERS molecular diagnosis. MERS TF established guidelines for laboratory diagnosis of MERS-CoV and provided it to all participating laboratories as the official guidance of MERS Joint committee. This guideline was used for procedure manual of molecular diagnosis of MERS-CoV and laboratory safety manual.
