RESUMO
Purpose@#To investigate risk factors of age-related macular degeneration (AMD) with routine health check-up data. @*Methods@#Among 9,019 patients older than 40 years who underwent a routine health checkup at a single institution of South Korea from January to December 2017, 7,018 patients were enrolled in this retrospective study. An additional 2,001 patients were accepted, due to the absence of a fundus photo or having a fundus photo of poor quality. @*Results@#Among 7,018 patients, 183 patients were diagnosed with AMD. We diagnosed 104 patients with early-phase, 75 patients with intermediate-phase, and 4 patients with late-phase AMD. The AMD groups were compared to a control group using one-way analysis of variance. The control, early, and intermediate groups showed meaningful differences with respect to age. In propensity score matching for age and sex, no differences were observed with respect to blood pressure, body mass index, or weight; however, significant differences were evident for the parameters of hepatitis B surface antigen, alkaline phosphatase, platelet, erythrocyte sedimentation rate, gamma glutamyl transferase, high density lipoprotein (HDL), carcinoembryonic antigen (CEA), C-reactive protein (CRP), status of exercise, drinking, and smoking between the control and AMD groups. In multiple logistic regression analyses with relevant factors, a strong positive relationship was established for hepatitis B surface antigen, HDL, CRP and CEA elevation, absence of exercise, and current smoking in AMD patients. @*Conclusions@#Risk for AMD was strongly correlated with hepatitis B surface antigen, elevation of HDL, CEA and CRP in blood tests, the absence of exercise, and a history of smoking.
RESUMO
Objective@#This study aimed to identify the appropriateness of the Korean Triage and Acuity Scale (KTAS) for dizziness without neurological symptoms, which was level 3. @*Methods@#Using the registry of the National Emergency Department Information System (NEDIS), data regarding consecutive emergency patients from January 2016 to July 2018, who were aged 15 years and older, were reviewed retrospectively. The data were classified using KTAS and Dizziness KTAS level 3 were compared with non-dizziness KTAS level 3 including age, total admission rate, intensive care unit (ICU) admission rate, discharge rate, hospital cost, and length of stay in the emergency department (length of stay [LOS]). @*Results@#Of the 76,153 emergency patients, 345 (0.5%) had a KTAS level 1, 4,593 (6.0%) had a KTAS level 2, 21,561 (28.3%) had a KTAS level 3, 45,390 (59.6%) had a KTAS level 4, and 4,264 (5.6%) had a KTAS level 5. As the patient’s triage score decreased, the total admission rate, ICU admission rate, hospital cost, and LOS decreased. Patients discharged to home also had the same result. Dizziness KTAS level 3 had a significantly lower rate of total admission (23% vs. 56.2%, P<0.001) and ICU admission (0.9% vs. 6.2%, P<0.001) compared with non-dizziness KTAS level 3. On the other hand, the hospital cost and LOS were higher when patients were discharged to their home. The predictors of the admission rate of dizziness KTAS level 3 were the transportation method using a private ambulance service and older age, but older age was only slightly associated. @*Conclusion@#This study showed that KTAS level 3 for dizziness needs to be adjusted because of lower severity than other level 3. Old age and the transportation method should be considered factors.
RESUMO
PURPOSE: We report two cases of uveo-meningeal syndrome involving the retina, uvea, and optic disc in both eyes after viral meningitis. CASE SUMMARY: A 16-year-old female was referred to our department with blurred vision in both eyes. She was hospitalized in the pediatric ward with viral meningitis. She showed a norma best-corrected visual acuity (BCVA) and normal intraocular pressure in both eyes, but had severe inflammation in the anterior chamber on slit lamp examination, and optic disc edema and multiple whitish lesions on fundus examination. She was treated with intravenous antibiotic injections and steroid eye drops. After close observation, inflammation in the anterior chamber, optic disc edema, and the multiple whitish lesions in the retina were improved. A 27-year-old male who was treated for viral meningitis at the neurology department was referred to us with blurred vision in both eyes. His BCVAs were 0.7 (right eye) and 0.6 (left eye). The intraocular pressure was normal in both eyes. Slit lamp examination revealed inflammation in the anterior chamber and optic disc edema, and a fundus examination revealed multiple infiltrations. He received treatment for presumed herpes virus infection. After close observation, inflammation in the anterior chamber, optic disc edema, and multiple infiltrations with hemorrhage in the retina were improved. CONCLUSIONS: Clinicians should consider the possibility of uveo-meningeal syndrome, which can cause inflammation in the uvea,retina, and optic disc simultaneous with viral meningitis accompanying blurred vision.

OBJECTIVE: This study compared the prognosis of patients who visited the trauma center directly (direct visit group) with those transferred from the non-trauma center (transferred group). METHODS: The patients, who were 18 or older with Injury Severity Score of 15 or more in the trauma center at Busan, were studied from October 2015 to October 2016. To compare the treatment time between the direct visit and transferred group, first treatment time, final treatment time, and time to visit the trauma center were examined. To compare the prognosis, this study compared the 48-hour, 7-day, and in-hospital mortality rate as well as the duration of intensive care unit (ICU) and total hospital stay. To analyze the factors affecting the outcome of transferred group, the physician's level and procedures that had been performed at the non-trauma center were examined. RESULTS: The mortality was similar in the direct visit and transferred group (48-hour 7.6% vs. 4.6%, P=0.111; 7-day 11.1% vs. 7.2%, P=0.89; and in-hospital 14.6% vs. 11.3%, P=0.214). The length of ICU and total hospital stay were similar in the two groups. The mortality was higher in the patients in the transferred group when using intubation, transfusion, and pressure intensifier. The intubated patients showed higher mortality according to logistic regression. CONCLUSION: The mortality, length of ICU, and hospital stay were similar but the time to visit the trauma center and the final treatment time were longer in transferred group. Stabilizing the patient at the near non-trauma center may be more helpful for some patients.

OBJECTIVES: The aims of this study were to know the frequency of cognitive dysfunction among patients with autoimmune thyroid disorders, and to reveal influencing factors on it, especially to clarify association with autoimmune thyroid antibodies. METHODS: From sixty-five female patients with autoimmune thyroid disorders, demographic data were obtained by structured interview. Their cognitive funtions were measured using the MMSE-K and the MoCA-K tests. Depression was evaluated by the K-HDRS. RESULTS: 1) Among patients with autoimmune thyroid disorders, 7.69% of them were below 24 on the MMSE-K, while 10.77% were below 22 on the MoCA-K. The frequency of cognitive deficit was not significantly different according to having positivity to antimicrosomal antibodies or not. 2) The antimicrosomal antibody-positive patients had significantly higher antithyroglobulin antibody titers, antimicrosomal antibody titers, and TSH concentration, while had significantly lower free T4 levels(p<0.05, respectively). 3) The total scores of the MMSE-K and the MoCA-K had significant correlation with age, marital status, antithyroglobulin antibody titers and K-HDRS(p<0.05, respectively). 4) The regression analysis revealed that variables such as age, education, autoimmune thyroid antibodies, thyroid function and depression did not influence on cognitive function of patients with autoimmune thyroid disorders. CONCLUSIONS: Our results could not support that cognitive function of patients with autoimmune thyroid disorders had correlation with autoimmune thyroid antibodies.

PURPOSE: Inadequate treatment of pain, which has been termed as “oligoanalgesia”, appears to be common phenomenon the emergency department (ED). In order to improve pain recognition and management, a study concerning physician characteristics on pain and pain management is needed. METHODS: This study was based on a survey that targeted emergency medicine doctors from September to November 2015 (the response rate was 7%). Firstly, the survey showed that physicians preferred medicating on five diseases abdominal pain, cancer, simple musculoskeletal disease, trauma, headache in the ED. Secondly, it demonstrated the criteria used to choose the analgesic treatment in accordance with each disease and the level of pain, which is determined using a numerical rating scale (NRS). RESULTS: In the cases of abdominal pain that requires surgery, cancer pain, and multiple trauma, physicians preferred using an opioid as the first medication, while non steroidal anti inflammatory drugs (NSAIDs) are prescribed in most of the other cases. Meperidine was the preferred choice as the opioid. For almost diseases, the NSAIDs are selected in the lower NRS cases over the opioid. Physicians deal with pain of patients who are already diagnosed with specific diseases, such as cancer, while they avoid managing pain from those patients who have not been definitively diagnosed with a specific disease. CONCLUSION: Physicians in the ED prefer the use of NSAIDs as the analgesic treatment, in particular, prescribing meperidine as the preferred opioid. However, it seems that they are hesitant to manage pain without a clear diagnosis.

Antithymocyte globulin (ATG) is used as an immunosuppressive treatment (IST) to deplete clonal suppressor T cells in patients with severe aplastic anemia (SAA). The depletion of suppressor T cells by ATG may affect the activation of B cells, which results in an increased risk for autoimmune conditions. A 12-year-old boy was diagnosed with idiopathic SAA. As he did not have an human leukocyte antigen-matched sibling, he was treated with rabbit ATG (3.5 mg/kg/day for 5 days) and cyclosporine. Five months later, he became transfusion independent. However, 23 months after IST, he complained of mild hand tremors, sweating, weight loss, palpitations, and goiter. Results of thyroid function tests revealed hyperthyroidism (free thyroxine, 3.42 ng/dL; thyroid stimulating hormone [TSH], <0.01 nIU/mL; triiodothyronine, 3.99 ng/mL). Results of tests for autoantibodies were positive for the antimicrosome antibody and TSH-binding inhibitory immunoglobulin, but negative for the antithyroglobulin antibody and antinuclear antibody. He was treated with methimazole, and his symptoms improved. The patient has been disease free for 39 months after IST and 9 months after methimazole treatment. This case report suggests that although rare, rabbit ATG may have implications in the pathogenesis of autoimmune hyperthyroidism. Our findings suggest that thyroid function tests should be incorporated in the routine follow-up of SAA patients treated with ATG.

It is uncommon for pediatric patients with rhabdomyosarcoma to present with clinical and/or laboratory features of disseminated intravascular coagulation (DIC). We report a case of metastatic alveolar rhabdomyosarcoma with severe bleeding because of DIC in a 13-year-old boy. He experienced persistent oozing at the site of a previous operation, gross hematuria, and massive epistaxis. Two weeks after initiating combination chemotherapy consisting of vincristine, doxorubicin, and cyclophosphamide, the patients' laboratory indications of DIC began to resolve. During this period, the patient received massive blood transfusion of a total of 311 units (26 units of red blood cells, 26 units of fresh frozen plasma, 74 units of platelet concentrates, 17 units of single donor platelets, and 168 units of cryoprecipitate), antithrombin-III and a synthetic protease inhibitor. Despite chemotherapy and radiation therapy, he died 1 year later because of disease progression. In children with metastatic rhabdomyosarcoma and massive DIC, prompt chemotherapy and aggressive supportive care is important to decrease malignancy-triggered procoagulant activities.

PURPOSE: This study aim to investigate the occurrence of autoimmune thyroid disease in children and adolescents at onset of type 1 diabetes mellitus (T1DM) and to assess whether the presence of diabetes-specific autoantibodies can predict the autoimmune thyroid disorder. METHODS: Seventy-three children with T1DM were recruited. Glutamic acid decarboxylase antibodies (GADA), islet cell antibodies (ICA), insulin autoantibodies (IAA), and thyroid antibodies were determined in all patients at the time of diagnosis. RESULTS: The majority of patients (87.7%) had at least one pancreatic antibody (74.0% for GADA, 20.5% for ICA, and 24.7% for IAA). Thyroid autoantibodies were found in 19 of 73 patients (26.0%) at diagnosis. Thyroid autoimmunity (TA) incidence was not statistically significant by GADA or ICA positivity, but significantly higher by IAA positivity (P=0.03), and IAA positivity showed odds ratio, 4.931; 95% confidence interval, 1.323-18.381 for TA. CONCLUSION: The IAA positivity in children and adolescents with TIDM was strongly related to positivity of thyroid autoantibodies and thus it could serve as an index for early prediction of the development of the thyroid autoimmune disorder among children and adolescents with TIDM.

PURPOSE: The aim of this study was to characterize Korean patients with Fanconi anemia (FA), which is a rare but very challenging genetic disease. METHODS: The medical records of 12 FA patients diagnosed at Chonnam National University Hospital from 1991 to 2012 were retrospectively reviewed. RESULTS: The median age at diagnosis was 6.2 years. All patients showed evidence of marrow failure and one or more physical stigmata. Chromosome breakage tests were positive in 9 out of 11 available patients. The median follow-up duration was 69.5 months. The Kaplan-Meier (KM) survival of all patients was 83.3% at 10 years and 34.7% at 20 years, respectively. Seven patients underwent 9 stem cell transplantations (SCTs). Among them, 5 were alive by the end of the study. Ten-year KM survival after SCT was 71.4% with a median follow-up of 3.4 years. All 5 patients treated with supportive treatment alone died of infection or progression at the median age of 13.5 years, except for one with short follow-up duration. Acute leukemia developed in 2 patients at 15.4 and 18.1 years of age. Among 6 patients who are still alive, 3 had short stature and 1 developed insulin-dependent diabetes mellitus. CONCLUSION: We provide information on the long-term outcomes of FA patients in Korea. A nation-wide FA registry that includes information of the genotypes of Korean patients is required to further characterize ethnic differences and provide the best standard of care for FA patients.

The growing teratoma syndrome (GTS) is defined as the development of mature low-grade elements in the absence of a recurrent non-germinomatous germ-cell tumor (NGGCT) after partial response to multimodal treatment. It is uncommon and may occur in intracranial NGGCTs. Here, we report that a 7-year-old boy with intracranial NGGCT presented with precocious puberty and developed growing teratoma syndrome only 2 weeks after the first cycle of chemotherapy.

Armeniacae semen (AS) has been considered a toxic herb in the Korean medicine as it contains hydrogen cyanide and amygdalin, especially in its endocarp. Therefore, prebrewed AS that is devoid of endocarp has been traditionally used. In the present study, amygdalin content of the prebrewed AS was significantly lower (2.73 +/- 0.32 microg/ml; p < 0.01) than the content in the extract that contained the endocarps (28.50 +/- 6.71 microg/ml); amygdalin content corresponded to 10% of the extract in the present study. Because of single oral dose toxicity of prebrewed AS according to the recommendation of Korea Food and Drug Administration Guidelines (2009-116, 2009), which was based on single oral dose toxicity study of prebrewed AS, mortality due to toxic principles was significantly reduced. In this study, 2,000 mg/kg of prebrewed AS led to death of 1 female rat and 1 male rat at the end of 2 hr of administration. Based on these results, the 50% lethal dose in both male and female rats was determined to be 9279.5 mg/kg. Seizure, loss of locomotion, and increases in respiration and heart rate were observed as prebrewed AS treatment-related toxicological signs; these signs were restrictedly manifested in the prebrewed AS (2,000 mg/kg)-treated rats. In addition, no changes were observed in body weight, organ weight, gross features, and histopathological parameters with 2,000 mg/kg of AS in both male and female rats. These findings serve as direct evidence that amygdalin in AS is the toxic principle, which can be reduced by the traditional prebrewing method involving the exclusion of endocarp.

PURPOSE: The repopulating lymphocytes after allogeneic hematopoietic stem cell transplantation have an important role not only on the prevention of serious infections in the early transplantation period, but also on the killing of residual leukemic cells by graft-versus-leukemia effect. The aim of this study was to analyze the impact of lymphocyte recovery after allogeneic stem cell transplantation in children with hematologic malignancies. MATERIALS AND METHODS: We evaluated 69 children transplanted for acute lymphoblastic leukemia (ALL) (n=34), acute myeloid leukemia (AML) (n=26), chronic leukemia (n=7) and juvenile myelomonocytic leukemia (n=2) between 1996 and 2008 at the Chonnam National University Hospital, Korea. The patients were grouped based on absolute lymphocyte counts (ALC) or =500/microL at D+21 and D+30 after transplant. RESULTS: Patients with a High ALC at D+21 and D+30 had a faster neutrophil and platelet engraftment. The High at D+30 group had a better 5 year overall survival (71% vs. 53%, p=0.043) and event-free survival (72% vs. 53%, p=0.065) than the Low at D+30 group. The incidence of grade II-IV acute and chronic graft-versus-host disease (GVHD), and relapse rate did not differ by the ALC counts. However, the Low at D+30 group had a significantly increased risk for transplant-related mortality (p=0.019). The univariate analysis showed that the factors associated with decreased survival were a Low ALC at D+30, patients with high risk ALL, and grade II-IV aGVHD in patients with ALL and AML. CONCLUSION: Early posttransplant serial lymphocyte measurement would be a simple but useful method for predicting transplant outcomes.

BACKGROUND: The number of patients diagnosed with hereditary hemolytic anemia (HHA) has increased since the advent of novel diagnostic techniques that accurately identify this disorder. Here, we report data from a survey on the prevalence and characteristics of patients diagnosed with HHA in Korea from 2007 to 2011. METHODS: Information on patients diagnosed with HHA in Korea and their clinical and laboratory results were collected using a survey questionnaire. Globin gene and red blood cell (RBC) enzyme analyses were performed. In addition, we analyzed data collected by pediatricians. RESULTS: In total, 195 cases of HHA were identified. Etiologies identified for HHA were RBC membranopathies, hemoglobinopathies, and RBC enzymopathies, which accounted for 127 (64%), 39 (19.9%), and 26 (13.3%) cases, respectively. Of the 39 patients with hemoglobinopathies, 26 were confirmed by globin gene analysis, including 20 patients with beta-thalassemia minor, 5 patients with alpha-thalassemia minor, and 1 patient with unstable hemoglobin disease. CONCLUSION: The number of patients diagnosed with hemoglobinopathies and RBC enzymopathies has increased considerably since the previous survey on HHA in Korea, dated from 1997 to 2006. This is likely the result of improved diagnostic techniques. Nevertheless, there is still a need for more sensitive diagnostic tests utilizing flow cytometry and for better standardization of test results to improve the accuracy of diagnosis of RBC membranopathies in Korea. Additionally, more accurate assays for the identification of RBC enzymopathies are warranted.

Plastic bronchitis is an uncommon disorder characterized by the formation of bronchial casts. It is associated with congenital heart disease or pulmonary disease. In children with underlying conditions such as allergy or asthma, influenza can cause severe plastic bronchitis resulting in respiratory failure. A review of the literature showed nine cases of plastic bronchitis with H1N1 including this case. We report a case of a child with recurrent plastic bronchitis with eosinophilic cast associated with influenza B infection, who had recovered from plastic bronchitis associated with an influenza A (H1N1) virus infection 5 months previously. To the best of our knowledge, this is the first case of recurrent plastic bronchitis related to influenza viral infection. If patients with influenza virus infection manifest acute respiratory distress with total lung atelectasis, clinicians should consider plastic bronchitis and early bronchoscopy should be intervened. In addition, management for underlying disease may prevent from recurrence of plastic bronchitis.

The clinical features of ring chromosome 6 include central nervous system anomalies, growth retardation, facial dysmorphism and other congenital anomalies. Ring chromosome 6 occurs rarely and manifests as various phenotypes. We report the case of mosaic ring chromosome 6 by conventional karyotyping in a 7-day-old male infant diagnosed with a large patent ductus arteriosus (PDA) with hypoplasia of aortic valve and aortic arch. These have not been previously reported with ring chromosome 6. He recovered from heart failure symptoms after ligation of the PDA. He showed infantile failure to thrive and delayed milestone in a follow-up evaluation. To the best of our knowledge, this is the first report of a Korean individual with ring chromosome 6 and hemodynamically significant PDA.

PURPOSE: The purpose of this study is to evaluate the usefulness and necessity of an emergency medical service director program for board certified emergency physicians. METHODS: A retrospective analysis of records of direct medical advice provided by board certified emergency physicians in the Busan area from April 1, 2011 to July 11, 2011 was conducted. The medical and legal validity of the medical direction was evaluated by two independent emergency physicians with experience and certification in the field of medical control. RESULTS: Fifteen emergency physicians provided direct medical control during the study period. Five of them were certified as an emergency medical service (EMS) director by the Korean council of EMS physicians (KCEMSP), and the other 10 were not. An analysis of 992 cases of direct medical direction was performed. No differences in the diagnostic appropriateness and medical validity of medical advice were observed between the two groups. A significant difference was observed in legal validity (p=0.048). However, in multivariate analysis, experience as a certified emergency physician was a significant factor determining legal validity (p=0.02), while certification by the KCEMSP was not significant. CONCLUSION: The current EMS director certification program did not have a significant influence on the appropriateness of direct medical direction. EMS director courses and emergency medicine residency programs are in need of improvement in the legal aspect of prehospital emergency service.
