Purpose: This study aimed to determine the impact of an intervention using voice recording of family members on pain, anxiety, and agitation in patients undergoing weaning from mechanical ventilation. Methods: A randomized control pre-post experimental design was implemented to 53 participants, with 27 and 26 participants in the experimental and control groups, respectively. A 70-second voice recording of a family member, repeated three times at 10-minute intervals was used as an intervention for the experimental group. Meanwhile, participants in the control group used headset for 30 minutes. Structured instruments were utilized to measure pain, anxiety, agitation, and the weaning process. Wilcoxon Signed Ranks test and the Mann-Whitney U test, or χ2 test, were used for data analysis. Results: The experimental group exhibited significant decrease in pain (Z = - 3.53, p < .001), anxiety (t = 5.45, p < .001), and agitation (Z = - 2.99, p = .003) scores compared with those of the control group. However, there was no significant difference between groups in the weaning process’ simplification (χ2 = 0.63, p = .727). Conclusion Intervention using family members’ voice recording effectively reduces pain, anxiety, and agitation in patients undergoing weaning from mechanical ventilation. This can be actively utilized to provide a more comfortable process for patients.

Background: Multiple system atrophy (MSA) is a sporadic neurodegenerative disease characterized by various combinations of parkinsonism, cerebellar ataxia, autonomic dysfunction and pyramidal signs. Two clinical subtypes are recognized: MSA with predominant cerebellar ataxia (MSA-C) and MSA with predominant parkinsonism (MSA-P). The aim of this study was to compare pathological features between MSA-C and MSA-P. Methods: Two autopsy confirmed cases with MSA were included from the Pusan National University Hospital Brain Bank. Case 1 had been clinically diagnosed as MSA-C and case 2 as MSA-P. The severity of neuronal loss and gliosis as well as the glial and neuronal cytoplasmic inclusions were semiquantitatively assessed in both striatonigral and olivopontocerebellar regions. Based on the grading system, pathological phenotypes of MSA were classified as striatonigral degeneration (SND) predominant (SND type), olivopontocerebellar degeneration (OPC) predominant (OPC type), or equivalent SND and OPC pathology (SND=OPC type). Results: Both cases showed widespread and abundant α-synuclein positive glial cytoplasmic inclusions in association with neurodegenerative changes in striatonigral or olivopontocerebellar structures, leading to the primary pathological diagnosis of MSA. Primary age-related tauopathy was incidentally found but Lewy bodies were not in both cases. The pathological phenotypes of MSA were MSA-OPC type in case 1 and MSA-SND=OPC type in case 2. Conclusions Our data suggest that clinical phenotypes of MSA reflect the pathological characteristics.

Objectives: This study aimed to develop a Korean version of psychological first aid training program (K-PFA) and examine the education effect on trainees. Methods: This study enrolled 485 subjects who completed both K-PFA and study surveys. In addition to mental health professionals, subjects with various ages and educational backgrounds were included to examine the education effects of the capabilities in conducting PFA and understanding acute phase disaster mental health (DMH). Results: Both mental health professionals and non-professionals improved their understanding of acute-phase DMH intervention and their perceived capabilities in conducting PFA. Conclusion The development of a DMH intervention-training program adapted to Korean domesticcircumstances and culture represents a significant step towards a comprehensive and individualized intervention for disaster survivors.

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs. The group researched all articles and major foreign CPGs published in English until December 2015 using several search engines. Based on these articles, levels of evidence and grades of recommendations were determined by our society as well as by other related Quality Control Committees from neurointervention, neurology and rehabilitation medicine. The Korean version of the CPGs for aSAHs includes risk factors, diagnosis, initial management, medical and surgical management to prevent rebleeding, management of delayed cerebral ischemia and vasospasm, treatment of hydrocephalus, treatment of medical complications and early rehabilitation. The CPGs are not the absolute standard but are the present reference as the evidence is still incomplete, each environment of clinical practice is different, and there is a high probability of variation in the current recommendations. The CPGs will be useful in the fields of clinical practice and research.

The National Health Information Standards Committee was established in 2004 in Korea. The practical subcommittee for laboratory test terminology was placed in charge of standardizing laboratory medicine terminology in Korean. We aimed to establish a standardized Korean laboratory terminology database, Korea-Logical Observation Identifier Names and Codes (K-LOINC) based on former products sponsored by this committee. The primary product was revised based on the opinions of specialists. Next, we mapped the electronic data interchange (EDI) codes that were revised in 2014, to the corresponding K-LOINC. We established a database of synonyms, including the laboratory codes of three reference laboratories and four tertiary hospitals in Korea. Furthermore, we supplemented the clinical microbiology section of K-LOINC using an alternative mapping strategy. We investigated other systems that utilize laboratory codes in order to investigate the compatibility of K-LOINC with statistical standards for a number of tests. A total of 48,990 laboratory codes were adopted (21,539 new and 16,330 revised). All of the LOINC synonyms were translated into Korean, and 39,347 Korean synonyms were added. Moreover, 21,773 synonyms were added from reference laboratories and tertiary hospitals. Alternative strategies were established for mapping within the microbiology domain. When we applied these to a smaller hospital, the mapping rate was successfully increased. Finally, we confirmed K-LOINC compatibility with other statistical standards, including a newly proposed EDI code system. This project successfully established an up-to-date standardized Korean laboratory terminology database, as well as an updated EDI mapping to facilitate the introduction of standard terminology into institutions.

Choledochal cyst has only rarely been encountered in association with pregnancy. The clinical manifestations are nonspecific and variable that makes it difficult to differentiate from physiologic changes in pregnancy. Consequently, diagnosis is often delayed until patients present with life-threatening complications. During pregnancy, symptoms of choledochal cyst may be developed by hormonal changes and the enlarged uterus. Because of the risk of fetal mortality and maternal morbidity, definitive surgical treatment should be delayed and step-by-step management should be carefully implemented to avoid complication until delivery. Herein, we report a case of enlarged, symptomatic choledochal cyst that developed in a 26-year-old pregnant woman. The temporal relationship between pregnancy and symptom development, as well as the biliary sludge formation in the enlarged cyst, suggest that the choledochal cyst was influenced by pregnancy. In order to buy time for fetal maturation, endoscopic ultrasonography-guided choledochoduodenostomy was performed for biliary decompression as a bridge to surgical excision.

The Rh blood group D antigen is the most immunogenic of all antigens, next to ABO antigens. Anti-D immunization is clinically important since it may cause clinical problems, such as severe hemolytic transfusion reactions and hemolytic disease of the newborn. DEL is an extremely weak D variant that cannot be detected by basic serologic typing and is typed as D-negative without the absorption-elution techniques and RHD genotyping. Of the DEL phenotype, RHD (c.1227G>A) allelic variant is the most common in Korea. The DEL phenotype has been considered to carry only a few D antigens to induce anti-D immunization, but a few cases have reported that this allelic variant is capable of inducing anti-D immunization in a D-negative recipient, for which it is clinical significant. Herein, we present a case of primary anti-D alloimmunization in a RhD negative patient after receiving RHD (c.1227G>A) DEL red cell transfusion identified by serological and molecular tests, including RHD genotyping.

BACKGROUND: Transfusion-related adverse reaction is detected based on patients' adverse signs or symptoms during or after transfusion. We analyzed the actual incidence of transfusion-related adverse reactions by investigating diagnosed cases among reported signs or symptoms, and reexamined our transfusion-related adverse reaction reporting system. METHODS: From January to June, 2015, there were 4,234 cases of transfusion and 18,191 units of blood product were used. During transfusion, patients' signs or symptoms were checked and reported by the medical team at least three times, 5 minutes after transfusion started, during transfusion, and after transfusion, using the electronic reporting system in the blood bank. A laboratory medicine doctor investigated reported signs or symptoms by reviewing patients' electronic medical records, diagnosed transfusion-related adverse reaction by textbook definition, and surveyed actual incidence. In addition, incidence of transfusion-related signs or symptoms and transfusionrelated adverse reaction by each blood product was determined. RESULTS: Out of 1,091 transfusion-related signs or symptoms, only 226 cases (20.71%) were diagnosed with transfusion-related adverse reaction. Among these, most common cases were febrile nonhemolytic reaction with incidence of 0.91%, followed by allergic reaction with 0.32%. The incidence of transfusion-related adverse reaction by each blood product was highest for leukocyte-reduced red blood cells 3.41% and apheresis platelets 2.59%. Febrile nonhemolytic reaction was mainly related to red blood cells and allergic reaction was mainly related to platelets. CONCLUSION: The actual incidence of transfusion-related adverse reaction was only 20% of transfusion-related signs or symptoms. Therefore, reforming the reporting system and transfusion-related clinical inspection and education are required.

OBJECTIVE: Aneurysms arising from the pericallosal artery (PA) are uncommon and challenging to treat. The aim of this study was to report our experiences of the endovascular treatment of ruptured PA aneurysms. METHODS: From September 2003 to December 2013, 30 ruptured PA aneurysms in 30 patients were treated at our institution via an endovascular approach. Procedural data, clinical and angiographic results were retrospectively reviewed. RESULTS: Regarding immediate angiographic control, complete occlusion was achieved in 21 (70.0%) patients and near-complete occlusion in 9 (30.0%). Eight procedure-related complications occurred, including intraprocedural rupture and early rebleeding in three each, and thromboembolic event in two. At last follow-up, 18 patients were independent with a modified Rankin Scale (mRS) score of 0-2, and the other 12 were either dependent or had expired (mRS score, 3-6). Adjacent hematoma was found to be associated with an increased risk of poor clinical outcome. Seventeen of 23 surviving patients underwent follow-up conventional angiography (mean, 16.5 months). Results showed stable occlusion in 14 (82.4%), minor recanalization in two (11.8%), and major recanalization, which required recoiling, in one (5.9%). CONCLUSION: Our experiences demonstrate that endovascular treatment for a ruptured PA aneurysms is both feasible and effective. However, periprocedural rebleedings were found to occur far more often (20.0%) than is generally suspected and to be associated with preoperative contrast retention. Analysis showed existing adjacent hematoma is predictive of a poor clinical outcome.

OBJECTIVES: Drinking alcohol during pregnancy can result in various negative consequences. Nevertheless, few studies have been conducted in Korea to investigate alcohol consumption and factors influencing drinking behavior during pregnancy in Korean women. A survey was therefore conducted on pregnant women to investigate whether they drank alcohol and to identify factors predictive of drinking behavior during pregnancy. METHODS: Pregnant women at less than 30 days before expected delivery were asked to complete a self-report questionnaire. Demographic and obstetric characteristics and smoking history were investigated in addition to their history of alcohol use. RESULTS: Six hundred and sixty five subjects of average age 30.8+/-3.8 years were enrolled. Five hundred fifty five (83.5%) and 163 subjects (24.5%), respectively, consumed alcohol before becoming pregnant and after they were aware of being pregnant. Ninety six (14.4% of 665 subjects) and 20 subjects (3.0% of 665 subjects), respectively, smoked before becoming pregnant and after they were aware of being pregnant. Those who had consumed alcohol before becoming pregnant (OR=12.13, p<0.001), those who smoked before becoming pregnant (OR=2.24, p=0.001) and those with a family history of smoking (OR=1.59, p< or =0.05) were found to be more likely to drink alcohol when pregnant. CONCLUSION: Three factors, alcohol drinking before becoming pregnant, cigarette smoking before becoming pregnant and a family history of cigarette smoking, are predictive of alcohol consumption during pregnancy. These results strongly suggest that an anti-drinking educational program should be devised to target women of child bearing potential and, in particular, those at high risk.
