Abalone is popular seafood in Asia; however, allergy to abalone was rarely reported. We report a case of anaphylaxis after consumption of abalone. A 24-year-old female visited an Emergency Department, complaining of cough, dyspnea, rhinorrhea, generalized urticaria, facial edema, and wheezing that had developed 1 hour after consumption of abalone. She was discharged when her symptoms subsided after antihistamine and dexamethasone were given. One month later, she was referred to our outpatient clinic. We performed skin prick tests, measurement of serum specific IgE antibody level, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with IgE immunoblotting. Both skin prick and specific IgE antibody tests were positive for abalone crude extract. In SDS-PAGE with IgE immunoblotting, we identified possible antigens sized 55, 100, and 25 kDa, respectively. This is the first case of abalone-induced anaphylaxis in Korea.

PURPOSE: Veterinary researchers are exposed to variable animal allergens. However, sensitization to them and allergic symptoms during exposure to them in this group are not sufficiently evaluated worldwide, especially in Korea. The objective of this study is to evaluate sensitization to animal allergens and allergic symptoms during exposure to them in Korean veterinary researchers. METHODS: Thirty-two veterinary researchers who participated in the 2016 annual symposium of the Korean Society of Veterinary Science were asked to answer questionnaires regarding allergic symptoms during animal exposure and underwent skin prick tests for animal allergens. Animal allergens consisted of chicken feather and 10 mammals, epithelia as well as cow's milk, hen's egg, and 7 animal types of meat. RESULTS: There were 13 subjects who complained of allergic symptoms during exposure to certain animal epithelia and 19 who did not. Between the 2 groups, there were no differences in age, sex, underlying allergic disease, family history of allergy, current occupation and its duration, numbers and specie of contact animals, or daily contact time. Meanwhile, the sensitization rates to mouse, horse, rabbit, and guinea pig were significantly higher in the symptomatic group. Rhinoconjunctivitis symptoms were the most common allergic symptoms related to animal exposure were most common followed by dermatologic symptom, and symptom of lower respiratory tract. CONCLUSION: We found that sensitizations to some animal epithelia were more frequent in Korean veterinary researchers with allergic symptoms during exposure to animal compared to those without it, and their most common symptoms were rhinoconjunctivitis symptoms.

OBJECTIVE: There are conflicting reports about whether individual anxiety disorders are independently associated with suicidal ideation and suicide attempts. We examined whether anxiety disorders are related to suicidal ideation and suicide attempts in a community sample of South Korean adults. METHODS: In-person interviews based on the South Korean version of the Composite International Diagnostic Interview were conducted to diagnose mental disorders. Multivariate logistic regression analysis was performed to examine whether anxiety disorders were associated with suicidal ideation and suicide attempts. Each regression model treated lifetime diagnosis of anxiety disorders as independent variables. Sociodemographic characteristics, cohabitation status, lifetime history of mood disorders, alcohol use disorders, and psychotic disorders were included as covariates. RESULTS: Nationally representative sample of 6,510 South Korean adults aged 18–64 years was recruited. Multivariate analysis adjusted for psychiatric comorbidity and sociodemographic variables revealed that generalized anxiety disorder (GAD) [2.34, 95% confidence interval (CI) (1.27, 4.33)], post-traumatic stress disorder (PTSD) (3.50, 95% CI: 2.16, 5.68), specific phobia (1.55, 95% CI: 1.14, 2.11), social phobia (2.97, 95% CI: 1.27, 6.94), and obsessive-compulsive disorder (OCD) (5.58, 95% CI: 2.70, 11.6) were associated with suicidal ideation, whereas only social phobia (3.78, 95% CI: 1.41, 10.1) and PTSD (5.13, 95% CI: 2.81, 9.37) were associated with suicide attempts. CONCLUSION: Individual anxiety disorders are independently associated with suicidal ideation and/or suicide attempts. The importance of the early detection of anxiety disorders and of assessing the suicide risk in individuals with anxiety disorders is emphasized.

OBJECTIVES: This report seeks to introduce some cases of the patients who received magnetic resonance imaging (MRI)-guided high intensity focused ultrasound (HIFU) surgery (MRgFUS)-based intramural uterine fibroids treatment where the post-MRgFUS intramural uterine fibroids decreased in its volume and protruded towards the endometrial cavity to be expelled by hysteroscopy. METHODS: Of the 157 patients who had received MRgFUS treatment in the Obstetrics and Gynecology of the Hospital from March, 2015 to February, 2016; this study examined 6 of the cases where, after high intensity focused ultrasound treatment, intramural uterine fibroids protruded towards the endometrial cavity to be removed by hysteroscopic myomectomy. The high intensity focused ultrasound utilized in the cases were Philips Achieva 1.5 Tesla MR (Philips Healthcare, Best, The Netherlands) and Sonalleve HIFU system. RESULTS: The volume of fibroids ranged from 26.0 cm³ to 199.5 cm³, averaging 95.6 cm³. The major axis length ranged from 4.0 cm to 8.2 cm, averaging 6.3 cm. Fibroid location in all of the patients was in intramural uterine before treatment but after the high intensity focused ultrasound treatment, the fibroids were observed to protrude towards the endometrial cavity in at least Day 5 or up to Day 73 to allow hysteroscopic myomectomy. CONCLUSIONS: In some cases, after an intramural uterine fibroid is treated with MRgFUS, fibroid volume is decreased and the fibroid protrudes towards the endometrial cavity. In this case, hysteroscopic myomectomy can be a useful solution.

OBJECTIVES: Magnetic resonance imaging (MRI)-guided high intensity focused ultrasound surgery (MRgFUS) is a newly emerging non-invasive technique for the treatment of uterine fibroids. The purpose of this study is to review the clinical impact of MRgFUS. METHODS: This study examined 157 patients. The high intensity focused ultrasound (HIFU) utilized in this study was Philips Achieva 1.5 Tesla MR (Philips Healthcare, Best, the Netherlands) and Sonalleve HIFU system. The patients were followed in post-operative Month 1, Month 3, and Month 6 to investigate any change. Then, these were further classified according to the use of uterine stimulant (oxytocin) in parallel, Funaki Type of uterine fibroid, HIFU intensity, and non-perfused volume (NPV) ratio. RESULTS: When the uterine stimulant was utilized, the HIFU intensity was measured at significantly lower levels, compared with the group not using uterine stimulant, and treatment duration was significantly. The NPV ratio was found significantly higher in the group using uterine stimulant. Concerning the correlation between Funaki Type of uterine fibroid and average sonication power, it was found that the closer to Type I, the lower the sonication power, the shorter the treatment duration, and the higher the NPV ratio significantly. CONCLUSIONS: In this study, it was found that the lower the Funaki Types of uterine fibroids, and the higher the NPV ratio immediately after the operation, the larger the uterine fibroid volume decrease and SSS change were. Also, if uterine stimulant was used in parallel in treatment, treatment duration and HIFU intensity could become shorter and lower.

OBJECTIVES: The aim of this study is to investigate the association between serum uric acid level and metabolic syndrome according to menopausal status in Korean women. METHODS: A total of 2,241 women who visited to the health promotion center at Pusan National University Hospital from 2010 to 2014 were included in this cross-sectional study. Self-report questionnaires and interviews with healthcare providers were used to assess disease history, medication history, menstrual history and body size measuring. Anthropometric measurements and laboratory results were compared as presence of metabolic syndrome and menopausal status by student-t test. Logistic regression analysis was performed between presence of metabolic syndrome and presumable predictive factors, such as age, menopause and serum uric acid. RESULTS: The prevalence rate of metabolic syndrome were 7.45% (63/846) in pre-menopausal group and 23.87% (333/1395) in menopausal group. Serum uric acid level was higher in menopausal women than premenopausal women (4.6 +/- 1.1 vs. 4.3 +/- 0.9. P = 0.000). And, its concentration was also higher in metabolic syndrome than normal women regarding of menopausal statue (premenopause 4.7 +/- 1.1 vs. 4.2 +/- 0.8, P = 0.001, menopause 4.9 +/- 1.3 vs. 4.5 +/- 1.0, P = 0.000). Multiple logistic regression analysis showed serum uric acid and age have relationship with metabolic syndrome (OR: 1.453, 95% confidence interval [CI]: 1.074-1.111, P = 0.000; OR: 1.092, 95% CI: 1.305-1.619, P = 0.000). CONCLUSION: We could find out some potential of uric acid as predictive factor for metabolic syndrome in premenopausal and menopausal group. Further investigation is required to clarify the relationship between serum uric acid, menopause and metabolic syndrome.

Evidence suggests that diabetes mellitus (DM) is associated with idiopathic pulmonary fibrosis (IPF). According to the new IPF guidelines, high-resolution computed tomography (HRCT) is an essential means of diagnosing IPF. We investigated the relationship between IPF and DM in patients treated between 2003 and 2007. Newly diagnosed IPF patients in large university teaching hospitals in Korea were enrolled from January 2003 to December 2007. We retrospectively analyzed 1,685 patients using the interstitial lung disease (ILD) registry. In total, 299 IPF patients (17.8%) also had DM. The mean age of our subjects was 68.0 +/- 9.4 yr. HRCT showed significantly more reticular and honeycomb patterns in IPF patients with DM than in IPF patients without DM (P = 0.014, P = 0.028, respectively). Furthermore, significantly higher incidences of hypertension, cardiovascular diseases, and other malignancies (except lung cancer) were found in IPF patients with DM than in IPF patients without DM. In conclusion, IPF patients with DM are more likely to have the usual interstitial pneumonia (UIP) pattern, including reticular and honeycomb patterns, on HRCT than are those without DM.

BACKGROUND: Monoclonal antibodies (mAbs) recognizing Class III epitope of CD34 are essential for flow cytometric diagnosis of leukemia. METHODS: 27H2 mAb was developed from a mouse alternatively immunized with human acute leukemia cell lines, KG1 and Molm-1. Using flow cytometric analysis of various leukemic cell lines and peripheral blood, immunohistochemical study of frozen tonsil, we characterized 27H2 mAb. Antigen immunoprecipitated with 27H2 mAb immunobloted with anti-CD34 mAb. A case of bone marrow sample of acute lymphoblastic leukemia (ALL) patient was obtained at CBNU Hospital. For epitope identification enzyme treatment with neuraminidase and O-sialoglycoprotein endopeptidase (OSGE) and blocking assay with known classIII mAb (HPCA-2) were done. RESULTS: Only KG1 and Molm-1 revealed positive immunoreactivity. Immunohistochemical staining disclosed strong membranous immunoreactivity on high endothelial venules. Antigen immunoprecipitated by 27H2 mAb showed approximately 100 kDa sized band immunoblotted with anti-CD34 under non-reducing conditions. Epitope recognized by 27H2 mAb disclosed resistancy to both neuraminidase and OSGE treatment and completely blocked with known class III mAb preincubation. CD34 positive leukemic cells in BM of pre B cell ALL patient detected by FITC-conjugated 27H2 and HPCA-2 were identified with similar sensitivity. CONCLUSION: A novel murine mAb recognizing class III epitope of human CD34 with high affinity, which is useful for flow cytometric diagnosis of leukemia, was developed.

BACKGROUND/AIMS: The efficacy and safety of pemetrexed, gefitinib, and erlotinib administration in previously treated patients with non-small cell lung cancer (NSCLC) were compared. METHODS: The study patients met the following criteria: histologically confirmed, previously treated advanced (stage IIIB or IV) or recurrent NSCLC; a measurable lesion; > or = 18 years of age; Eastern Cooperative Oncology Group Performance status 0 to 2; and no prior exposure to the three study drugs. Patients received 500 mg/m2 of pemetrexed intravenously every 3 weeks with vitamin supplementation, gefitinib (250 mg/day per os), or erlotinib (150 mg/day per os). RESULTS: Of 57 patients (pemetrexed, 20; gefitinib, 20; and erlotinib, 17), 55 were evaluated for a response. The numbers of males, smokers, and squamous histology were increased in the pemetrexed group compared to the other groups. The objective response rates were 5.3%, 25.0%, and 12.5% (p = 0.22), and the disease control rates (DCR) were 5.3%, 40.0%, and 50.0%, respectively (p < 0.01). The median progression-free survival (PFS) was 1.7, 3.5, and 4.4 months (p < 0.01) and the median overall survival (OS) was 5.6, 21.8, and 21.5 months (p = 0.04), respectively. In subgroup analyses, patients with non-squamous histology, males, and a smoking history had a higher DCR and longer PFS with gefitinib and erlotinib than with pemetrexed. All three chemotherapeutic agents had manageable toxicities. CONCLUSIONS: Both oral epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) had comparable efficacy and safety. The superior PFS and OS of EGFR TKIs with more favorable baseline clinical characteristics than those of pemetrexed suggest the impact of baseline clinicopathological factors.

PURPOSE: This study was aimed to develop secondary triage rule for decision of interfacility transfer to higher level of trauma center for patients with traumatic brain injury (TBI). METHODS: In a prospective observational study from August 2006 to December 2007 conducted in an urban tertiary emergency department, data were obtained from patients more than 15 years old and with TBI. Primary outcome was defined as meaningful positive CT findings. Secondary outcome was defined as meaningful intervention. Non-adjusted univariated logistic regression model was derived from result of chi-square test and adjusted model was derived using stepwise selection manner. Hosman-Lemeshow test for the goodness of fit was used. RESULTS: Total number of eligible patients with traumatic brain injury was 653. Primary outcome was positive in 103 patients and secondary outcome was positive in 42 patients. In univariate logistic regression, risk factors were age over 65(OR: 2.40), history of cerebrovascular disease(OR: 7.08), fall over two meter(OR: 6.28), pedestrian struck(OR: 18.5), headache(OR: 2.18), vomiting(OR: 3.03), disorientation(OR: 5.37), any evidence of open fracture(OR: 24.03), Glasgow coma sacle less than 13(OR: 4.97), Racoon's eye sign (OR: 2.50). These 10 risk factors were statistically significant in adjusted model which was derived using stepwise selected manner. Hosman-Lemeshow test for the goodness of fit was used and chi-square was 1.307(p=0.86). This decision rule had a sensitivity of 93.48%, a specificity of 41.13%, and a negative predictive value of 97.32%. CONCLUSION: A sensitive clinical decision rule with high negative predictive value for detection of abnormal CT lesions which need transfer to higher level of trauma center was developed.
