ABSTRACT
BACKGROUND: Electronic Donor Health Questionnaire (e-DHQ) could prevent omissions in filling in the questionnaire. Compared with the paper Donor Health Questionnaire (p-DHQ), it can expect honest answers from donors to the questions relating to high risk behaviors. The aim of this study is to evaluate the effect of e-DHQ on the answers from donors by analyzing variations of the reasons for deferral after the introduction of e-DHQ to the Korean Red Cross (KRC). METHODS: The reasons for deferral determined by p-DHQ in 2008~2011 and by e-DHQ in 2011~2014, which have been accumulated in the database of the Blood Information Management System in KRC, were analyzed and compared. RESULTS: The results showed that the deferral rates for the general health status and medication taken were 0.47% (P=0.0100) and 0.16% (P=0.0103) higher in e-DHQ than in p-DHQ. In particular, for questions including hunger, lack of sleep, fatigue, endoscopy, dental treatment, surgery, tattoo, and acupuncture, the proportion of answers was higher in e-DHQ than in p-DHQ. CONCLUSION: The deferral rates for general health status and medication taken increased after the implementation of e-DHQ. The rate of deferral by some details of general health status, medical treatment for recent one month, and history for recent one year also increased because e-DHQ induced donors to give straightforward answers. e-DHQ is expected to contribute to the strengthening of health protection of blood donors and recipients. However the questions relating to high risk behaviors should be reformed so that honest answers can be induced from donors.

BACKGROUND AND PURPOSE: Centronuclear myopathy (CNM) is characterized by the presence of central nuclei within a large number of muscle fibers. Mutations of the dynamin 2 gene (DNM2) are common causes of autosomal dominant or sporadic CNM. The aim of this study was to characterize the clinical and pathological features of CNM relative to the presence of DNM2 mutations. METHODS: Six patients with clinical and pathological features of CNM were recruited. Detailed clinical and pathological findings were analyzed according to the presence of DNM2 mutations. RESULTS: We detected DNM2 mutations in four of the six sporadic CNM patients, and identified the following distinct clinical and pathological features in those patients with DNM2 mutations: preferential involvement of the distal lower limbs, typical nuclear centralization, and radially distributed sarcoplasmic strands in muscle pathology. In contrast, those without DNM2 mutations exhibited rather diffuse muscular involvement, and nuclear internalization and myofibrillar disorganization were more pronounced features of their muscle pathology. CONCLUSIONS: These findings suggest the presence of specific features in Korean CNM patients. A detailed clinical and pathological examination of CNM patients would be helpful for molecular genetic analyses of this condition.

BACKGROUND: It is important that hospitals conduct disaster drills to ensure prompt response in case of a pandemic and thereby prevent a biological disaster. METHODS: In a university hospital of Seoul, a drill was arranged by the members of the drill preparation team who were a part of the response team for infection control of novel influenza A (H1N1). The drill preparation team designed the scenario for the drill, made plans to resolve the potential problems that could occur during that scenario, and organized a survey team and a survey methodology. The scenario consisted of 2 modules: (1) for an intensive care unit and (2) for an emergency care center. The surveyors and field participants were evaluated after the drill exercise. RESULTS: This drill was conducted to improve the response to outbreaks of new infectious diseases. The drill event showed that the communication among the members responsible for the infection control was effective. However, the drill revealed certain drawbacks in the process; this drawbacks involved availability of adequate quarantine space, education on using personal protective equipments, assignment of medical and nonmedical staff, management of visitors, and installment of air-conditioners, heaters, and ventilation units in the areas with H1N1 outbreak. CONCLUSION: This drill helped to improve the process of infection control and overcome the drawbacks in the current process, and thereby helped in achieving positive outcome during the actual pandemic situation when the number of hospital visits and admissions because of H1N1 pandemic had rapidly increased. Although disaster plans and drills are not actively performed, the drill for infection control is essential because the risk for an outbreak of a new infectious disease is increasing.

The limb-girdle muscular dystrophy type 2A (LGMD2A) is a recessively inherited disease caused by a mutation of the calpain 3 gene (CAPN3), and is considered one of the most prevalent subtypes of limb-girdle muscular dystrophy (LGMD). In this study, we aimed to identify CAPN3 mutations and to characterize the phenotype of Korean patients with LGMD2A. Among 35 patients with LGMD, four patients, who showed calpain 3 deficiency on western blot analysis, were analyzed in this study. Total RNA extracted from frozen muscle tissue was amplified by reverse transcriptase polymerase chain reaction (RT-PCR) using six primer pairs covering all coding sequences of CAPN3, and direct sequencing was performed. Clinical and pathological features of the patients were also reviewed. We found four different mutations in five alleles from three patients. Of the pathogenic mutations identified, two were novel (c.2125T>C and c.2355-2357delTTC), and the others had been reported elsewhere (c.440G>C, c.1076C>T). All patients showed a high CK level with predominant proximal leg weakness, and the onset was in their childhood except for one patient. Among two novel CAPN3 mutations, one was a missense mutation (c.2125T>C [p.709Ser>Pro]), and the other was a small in-frame deletion causing omission of a single amino acid (c.2355-2357delTTC [p.786delPhe]). The clinical features of our patients were generally compatible with the characteristics of LGMD2A patients described in the previous studies.

Typhlitis or neutropenic enterocolitis is a life-threatening, necrotizing process of the cecum whose incidence is increasing. Typhlitis presents as fever, abdominal pain, and diarrhea in neutropenic patients. As the incidence of typhlitis increases, emergency physicians must be aware of this rapidly progressive and potentially fatal disease. The definitive management of typhlitis is controversial. The most prudent course for the emergency physician is to initiate aggressive medical management early in the ED. We describe a 25-year-old man with severe neutropenia presented to the emergency department with fever, abdominal pain, diarrhea that began 2days earlier. Abdominal computerized tomography(CT) demonstrated diffuse concentric thickening of the cecal wall, intramural edema, inflammatory bowel changes but no free air and abscess formation. He was recovered by early diagnosis and aggressive medical therapy. We report a case of typhlitis with literature reviews.

BACKGROUND: Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. SUBJECTS AND METHOD: In this retrospective study, subject is limited to transferred outborn babies with age less than 24 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. RESULTS: There were 84 cases(39.6%) hypothermia( among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. CONCLUSION: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.

Isolated infernal iliac artery aneurysms and rupture are relatively infrequent, often difficult to detect and therefore rarely considered in the differential diagnosis for abdominal pain. The consequences can be grave, The incidence of isolated iliac artery aneurysm is 1~2% of that of abdominal aortic aneurysm(AAA). The natural history is of gradual enlargement, with rupture the most common clinical presentation. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper surgical treatment before possible rupture. Here is a case of ruptured aneurysm of left internal iliad artery. A 73-year-old man was presented to our emergency center with severe abdominal pain and voiding difficulty Abdominal Computed Tomography(Cf) and angiography showed ruptured aneurysm of left infernal iliad artery. Emergency operation was successfully performed for the ruptured internal iliad artery aneurysm.
