PURPOSE: Several studies have suggested that many children have no symptoms before hospitalization with asthma exacerbations. The purpose of this study was to evaluate how many asymptomatic children were hospitalized for asthma exacerbation, and to analyze their prior symptoms. METHODS: Children over 3 years old, hospitalized for acute asthma exacerbation in the Pediatric Allergy and Respiratory Centers in the Kangnam St. Mary's Hospital from January 2003 to December 2006 were enrolled, and their medical records reviewed retrospectively. RESULTS: Among 142 identified patients (median age 5+/-2.5 yr), the group who developed asthmatic symptoms within four weeks before admission occupied about 18.5%. And the group who developed asthmatic symptoms in four weeks or acute exacerbation in six weeks before admission occupied about 23.2%. And group who had asthmatic symptoms in four weeks or acute exacerbation in six weeks or acute exacerbation one year before admission occupied about 31.6%. In September, the group who had no symptom before admission was larger than the group who had asthmatic symptom. The baseline characteristics of each group were not significantly different with respect to age, sex, past history or family history of allergic disease, UniCAP, total IgE and eosinophil count. CONCLUSION: Many children had no symptoms before admission for acute asthma exacerbation. Therefore, we suggest considering that a large number of patients with no previous symptoms are at great risk of acute exacerbation in September, when maintenance therapy is determined.

Ectopic breast tissue and male breast cancer are both very rare diseases with only a few reports in the literature. Here, we present the first case of ectopic male breast cancer in the perineum. The patient was a 70-year-old man with a palpable mass in the perineum. A wide local excision and inguinal lymph node dissection revealed invasive breast carcinoma of no special type involving the skin and subcutis, and inguinal lymph node metastases. Immunohistochemical staining showed that the tumor cells were strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2. Moreover, no p53 overexpression was observed. Herein, the clinical and pathologic features, as well as a review of ectopic male breast cancer are discussed.

PURPOSE: The frequency of diagnosis of each nodule category under the Bethesda classification was studied, and the differences in the results between cytopathologic and histopathologic analyses of same patients were assessed. Special attention was paid to the atypical cells of undetermined significance (ACUS), which is an intermediate category. The histopathology of ACUS specimens was confirmed to examine the clinical implication. METHODS: Patients (n=417) who underwent thyroid ultrasonography and fine needle aspiration of the thyroid since the application of Bethesda classification (November 2009 to August 2010) in this institution was enrolled in the study. RESULTS: According to the Bethesda criteria, of the 640 nodules there were 56 cases (8.8%) of ACUS, 14 cases (2.2%) of follicular neoplasm, 13 cases (2.0%) were suspicious for malignancy, and 37 cases (5.8%) were positive of malignancy. A total of 102 surgically-excised specimens were obtained, of which 40 specimens were previously categorized cytopathologically as ACUS. Of these 40 specimens, 16 cases (40%) were found to be malignant. CONCLUSION: A precise understanding of each diagnostic category seems to be necessary, which may help with treatment of patients with thyroid mass. This is especially true for ACUS, which was previously understood as an intermediate specimen, but which is actually a heterogeneous mix of benign specimen, benign specimen with various atypia, and malignancy. In case of ACUS, an extensive and accurate diagnostic approach utilizing various examination methods may be beneficial for the patient treatment.

Background: Korea recently established 70 emergency medical service areas. However, there are many concerns that medical resources for stroke could not be evenly distributed through the country. We aimed to compare the treatment quality and outcomes of acute stroke among the emergency medical service areas. Methods: This study analyzed the data of 28,800 patients admitted in 248 hospitals which participated in the 8th acute stroke quality assessment by Health Insurance Review and Assessment Service. Individual hospitals were regrouped into emergency service areas according to the address of the location. Assessment indicators and fatality were compared by the service areas. We defined the appropriate hospital by the performance of intravenous thrombolysis. Results: In seven service areas, there were no hospitals which received more than 10 stroke patients for 6 months. In nine service areas, there were no patients who underwent intravenous thrombolysis (IVT). Among 167 designated emergency medical centers, 50 hospitals (29.9%) responded that IVT was impossible 24 hours a day. There are 97 (39.1%) hospitals that meet the definitions of appropriate hospital. In 23 service areas (32.9%) had no appropriate or feasible hospitals. The fatality of service areas with stroke centers were 6.9% within 30 days and 15.6% within 1 year from stroke onset than those without stroke centers (7.7%, 16.9%, respectively). Conclusions There was a wide regional gap in the medical resource and the quality of treatments for acute stroke among emergency medical service areas in Korea. The poststroke fatality rate of the service areas which have stroke centers or appropriate hospitals were significantly low.

Background: There has been no comparison of the determinants of admission route between acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We examined whether factors associated with direct versus transferred-in admission to regional cardiocerebrovascular centers (RCVCs) differed between AIS and AMI. Methods: Using a nationwide RCVC registry, we identified consecutive patients presenting with AMI and AIS between July 2016 and December 2018. We explored factors associated with direct admission to RCVCs in patients with AIS and AMI and examined whether those associations differed between AIS and AMI, including interaction terms between each factor and disease type in multivariable models. To explore the influence of emergency medical service (EMS) paramedics on hospital selection, stratified analyses according to use of EMS were also performed. Results: Among the 17,897 and 8,927 AIS and AMI patients, 66.6% and 48.2% were directly admitted to RCVCs, respectively. Multivariable analysis showed that previous coronary heart disease, prehospital awareness, higher education level, and EMS use increased the odds of direct admission to RCVCs, but the odds ratio (OR) was different between AIS and AMI (for the first 3 factors, AMI > AIS; for EMS use, AMI < AIS). EMS use was the single most important factor for both AIS and AMI (OR, 4.72 vs. 3.90). Hypertension and hyperlipidemia increased, while living alone decreased the odds of direct admission only in AMI;additionally, age (65–74 years), previous stroke, and presentation during non-working hours increased the odds only in AIS. EMS use weakened the associations between direct admission and most factors in both AIS and AMI. Conclusions Various patient factors were differentially associated with direct admission to RCVCs between AIS and AMI. Public education for symptom awareness and use of EMS is essential in optimizing the transportation and hospitalization of patients with AMI and AIS.
