The aim of this study was to investigate time trends in the public awareness of stroke and its predicting factors. The target population was 9,600 community-dwelling adults, aged 19–79 years, in 16 metropolitan cities and provinces in Korea. The survey samples in 2012 and 2014 were selected separately (entirely different sets of subjects) using a proportionate quota sampling method. Information concerning knowledge of stroke and demographics was collected by trained telephone interviewers using random digit dialing. After excluding subjects with a non-response or refusal to answer any question, the analyses included 8,191 subjects in 2012 and 8,127 subjects in 2014. Respondents’ awareness of stroke warning signs (numbness or weakness, difficulty speaking or understanding speech, dizziness, visual impairment, and severe headache) was highest for difficulty speaking or understanding speech (80.9% in 2012 and 86.4% in 2014). There were significant increases in the proportion of respondents understanding the appropriate action (i.e., calling an ambulance) at the time of stroke occurrence (59.6% to 67.1%), and in the proportion aware of the general need for prompt treatment (86.7% to 89.8%). In multivariable logistic regression analysis, older age, higher education level, higher household income, current non-smoking, exposure to stroke-related public relations materials, and experience of stroke education were significantly associated with both high knowledge of stroke warning signs and awareness of the need for prompt treatment. Between 2012 and 2014, the public’s awareness of stroke increased significantly. More specialized interventions, including public relations materials and education, should focus on subgroups who have lower stroke knowledge.

PURPOSE: We investigated the prevalence and risk factors of allergic rhinitis (AR), nationwide in random children and adolescents of Korea. METHODS: A modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire survey was done in 1,820 children from elementary, middle, and high school nationwide in Korea. The subjects were selected by the stratifying sampling method by school grade and five regions. Current AR was defined as having AR symptoms during the last 12 months with a history of physician-diagnosed AR. Skin prick tests for 18 common allergens were performed. RESULTS: The number of males was 945, and that of females was 875. The mean age of the patients was 12.61+/-3.40 years. The prevalence of current AR and atopic current AR were 29.0% and 18.7%, respectively. Risk factors for current AR were male (adjusted odds ratio [aOR], 1.486; 95% confidence interval [CI], 1.189-1.856), family history of paternal AR (aOR, 3.208; 95% CI, 2.460-4.182), family history of maternal AR (aOR, 3.138; 95% CI, 2.446-4.025), antibiotic use in infancy (aOR, 1.547; 95% CI, 1.228-1.949), mold exposure during infancy (aOR, 1.416; 95% CI, 1.103-1.819), mold exposure during the last 12 months (aOR, 1.285; 95% CI, 1.012-1.630), and sensitization on skin prick tests (aOR, 2.596; 95% CI, 2.055-3.279). Risk factors for atopic current AR were the same as those of current AR, whereas breast-milk feeding (aOR, 0.720; 95% CI, 0.530-0.976) was a protective factor. Sensitized allergens as risk factors for current AR were Dermatophagoides pteronyssinus, Dermatophagoides farina, ragweed, mugwort, oak, alder, birch, Japanese hop, cat, and dog. CONCLUSION: The prevalences of current AR and atopic current AR were 29.0% and 18.7%, respectively. Male, sex parental AR, antibiotic use in infancy, mold exposure during the last 12 months, mold exposure during infancy, and atopic sensitization were risk factors for current AR. Breast-milk feeding was a protective factor for atopic current AR. Aeroallergen sensitization was an important risk factor for AR.

PURPOSE: Recent studies have established the association between hypotonic fluids administration and hospital-acquired hyponatremia in children, and have contended that hypotonic fluids be removed from routine practice. To assess current intravenous fluid prescription practices among Korean pediatric residents and to call for updated clinical practice education. METHODS: A survey-based analysis was carried out. Pediatric residents at six university hospitals in Korea completed a survey consisting of four questions. Each question supposed a unique scenario in which the respondents were to prescribe either a hypotonic or an isotonic fluid for the patient. RESULTS: Ninety-one responses were collected and analyzed. In three of the four scenarios, a significant majority prescribed the hypotonic fluids (98.9%, 85.7%, and 69.2%, respectively). Notably, 69.2% of the respondents selected the hypotonic fluids for postoperative management. Almost all (96.7%) selected the isotonic fluids for hydration therapy. CONCLUSION: In the given scenarios, the majority of Korean pediatric residents would prescribe a hypotonic fluid, except for initial hydration. The current state of pediatric fluid management, notably, heightens the risk of hospital-acquired hyponatremia. Updated clinical practice education on intravenous fluid prescription, therefore, is urgently required.

Cardiac amyloidosis describes a clinical disorder caused by infiltration of abnormal insoluble fibrils in the heart, characterized by progressive heart failure and a grave prognosis. Pleural effusion in cardiac amyloidosis may represent a sign of heart failure, but it can also result from pleural infiltration of amyloid, manifested by recurrent large fluid accumulations. Recently, the role of vascular endothelial growth factor (VEGF) has been implicated in the pathogenesis of refractory pleural effusion. We report a case of a 53 year-old female patient with cardiac amyloidosis who presented with recurrent accumulation of large pleural effusions. She was initially treated with high dose loop diuretics, but the pleural effusion persisted, with the daily amount of drainage averaging 1 L/day. Accumulation of pleural fluid did not subside after 3 cycles of melphalan/prednisolone therapy. After the introduction of bevacizumab, an anti-VEGF antibody, the amount of pleural effusion decreased significantly. Efficacy of anti-VEGF therapy for refractory pleural effusions needs to be defined through further studies.

We report here on a case of a spinal extradural leiomyoma in a 67-year-old woman, and this tumor was in a very unusual location for a leiomyoma. Because the patient underwent hysterectomy for a uterine leiomyoma 20 years ago, we can speculate that the spinal lesion was a metastatic leiomyoma.

OBJECTIVE: To compare the clinical outcomes between Day 2 and Day 3 embryo transfer(ET) groups in in vitro fertilization and embryo transfer(IVF-ET) with intracytoplasmic sperm injection(ICSI). METHODS: From May, 1997 to December, 1998, 174 cycles of IVF-ET with ICSI were performed and classified into two groups: Day 2 ET group(n=134) and Day 3 ET group (n=40). In Day 3 ET group, embryos fertilized after ICSI were cultured in vitro for further 24 hours in M3 media. RESULTS: There were no significant differences in the age and BMI of patients, basal serum FSH level, protocol of controlled ovarian hyperstimulation(COH), indication of ICSI, and source of sperm for ICSI between two groups. Only the number of the previous failed IVF-ET cycles was significantly higher in Day 3 ET group(p<0.05). Serum E2 level on hCG day, the numbers of oocytes retrieved after COH, oocytes fertilized after ICSI, and embryos transferred, and the rates of fertilization, cleavage, and implantation showed no significant differences. However, cumulative embryo score(CES) was significantly higher in Day 3 ET group(p<0.05). Although there were no significant differences in the rates of pregnancy per ET, spontaneous abortion, and live birth, the rates of biochemical and multiple pregnancy were significantly higher in Day 3 ET group(p<0.05). CONCLUSIONS: In IVF-ET with ICSI, the relatively higher CES may contribute to the higher risk of multiple pregnancy in Day 3 ET group, compared with the conventional Day 2 ET group.

Patients of choriocarcinoma with brain metastases are considered to have a very poor prognosis due to chemo-refractoriness and recurrence. So, selection and individualization of patients then followed by multimodality therapy are very important. We present a case of a patient who experienced twice of craniotomies due to intracranial hemorrhage and an emergent explorative laparotomy due to intestinal perforation of the metastatic sites of choriocarcinoma. She was treated with 12 cycles of high-dose MTX/EMA-CO, intrathecal MTX and WBRT. Eventually she has obtained a complete remission that ongoing for 2 years. So, we report this case with a brief review of the literatures.
