PURPOSE: To evaluate the effects of intravitreal aflibercept injection in the treatment of submacular hemorrhage secondary to neovascular age-related macular degeneration (nAMD). METHODS: This retrospective, observational study included patients diagnosed with nAMD with submacular hemorrhage treated with intravitreal aflibercept monotherapy. A total of 54 eyes of 54 patients were treated with an initial series of three monthly intravitreal aflibercept injections followed by as-needed injections. At the 6 month follow-up, changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and submacular hemorrhage area (SMH) were evaluated. RESULTS: The mean preoperative BCVA was 0.79 ± 0.59 logMAR, which improved significantly to 0.53 ± 0.46 logMAR at 3 months and 0.48 ± 0.50 logMAR at 6 months (p < 0.001, in both). The CMT significantly decreased in all eyes: preoperative, 454.4 ± 131.5 µm, to 242.6 ± 39.7 µm at 6 months. The SMH was also reduced in all eyes: preoperative, 6.4 ± 4.8 disc areas (DAs) to 0.8 ± 1.4 DAs at 6 months. Ten eyes were diagnosed with typical nAMD (18.5%) and 44 eyes were diagnosed polypoidal choroidal vasculopathy (81.5%). There was no significant difference at 6 months in the visual outcomes of the subgroups. CONCLUSIONS: Intravitreal aflibercept monotherapy is well-tolerated as a treatment in maintaining or improving vision in patients with SMH secondary to nAMD.

PURPOSE: To compare the characteristics of optical coherence tomography in eyes with treatment-naïve typical neovascular age-related macular degeneration (typical nAMD), polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP). METHODS: One hundred fifty-three eyes newly diagnosed with exudative AMD were retrospectively collected. All study eyes were classified into three subtypes: typical nAMD, PCV, and RAP. Subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging optical coherence tomography (EDI-OCT). Central macular thickness (CMT) and other OCT features including intraretinal cystoid fluid and subretinal fluid were also evaluated in all eyes. SFCT, CMT and other OCT features were compared among the three subtypes of exudative AMD. RESULTS: Seventy-four eyes with typical nAMD, 55 eyes with PCV, and 24 eyes with RAP were included. SFCT was significantly thickest in PCV and thinnest in RAP (p < 0.001). RAP showed the thickest CMT and the highest frequency of intraretinal cystoid fluid (p = 0.004, p < 0.001, respectively). CONCLUSIONS: In patients with exudative AMD, different characteristics of OCT were observed according to the three subtypes. Identification of OCT characteristics could help differentiate the subtypes of exudative AMD.

PURPOSE: To evaluate changes in subfoveal choroidal thickness (SFCT) after patterned panretinal photocoagulation (PRP) using pattern scan laser (PASCAL) in patients with diabetic retinopathy. METHODS: This study included 39 patients (50 eyes) treated with patterned PRP using PASCAL and who were followed for at least 3 months. Patients were classified into 2 groups according to severity: severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy. SFCT was measured by enhanced depth imaging of spectral-domain optical coherence tomography. The change in SFCT was analyzed at 1 and 3 months after PRP. RESULTS: SFCT was 270.42 ± 61.44 µm before PRP, 264.52 ± 60.78 µm at 1 month, and 255.74 ± 56.89 µm at 3 months after PRP. Significant change of SFCT was found at 3 months after PRP. Central macular thickness was 275.56 ± 50.61 µm before PRP and increased to 295.18 ± 52.80 µm and 293.10 ± 57.24 µm at 1 and 3 months post-treatment, respectively. There were no significant differences between groups in SFCT at baseline or in the amount of change in SFCT after PRP. CONCLUSIONS: SFCT significantly decreased after patterned PRP using PASCAL.

PURPOSE: VEGF, a potent angiogenic factor, increases vascular permeability and induces the fluid accumulation in the peritoneal and pleural cavities. This study is designed to know whether the VEGF concentration are associated with the formation of cystic fluid of thyroid nodules and the results of treatment. METHODS: To know whether thyroid follicular cells produce VEGF, we measured the VEGF concentration in the conditioned medium after primary culture of the normal thyroid follicular cells (NT 1.0). Thirty seven patients, who had visited Ajou University Medical Center, were divided into two groups; group A (n=19) is patients whose cystic nodules disappeared completely with 1 or 2 times fine needle aspirations. In Group B (n=18), the cystic nodules recurred rapidly and required aspiration more than 3 times. Clinical records of patients were analyzed and compared with TSH and VEGF levels in cystic fluids. RESULTS: The VEGF concentration in basal conditioned medium were 8.2±1.2 ng/ml in NT 1.0 and 8.2±0.6 ng/ml in thyroid cancer cell line (FTC-133). NT 1.0 was not affected by TSH stimulation. Mean concentration of TSH of all cystic fluids was 4.36µIU/ml (0.13~21.7) and there was no difference between 2 groups. Mean concentration of VEGF of all cystic fluids was 140.7 ng/ml (11.1~688.8). The VEGF concentration (287.9±289.6 ng/ml) in group B was significantly higher than that (104.2±97.1 ng/ml) in group A (P<0.05). CONCLUSION: This study suggests that thyroid follicular cells produce and secrete VEGF, and VEGF is related with the accumulation of cystic fluid in degenerative cysts of thyroid. Cysts with high VEGF concentration promote rapid reaccumulation of the cystic fluid and possibly necessitate operation in selected patients.

Chronic hepatitis is one of the leading cause of hospitalization and death in kidney transplanted patient. Korea is one of the endemic area of chronic hepatitis B. The impact of hepatitis B virus (HBV) infection on the clinical course of renal transplant recipient has been controversial. We describe five Hepatitis B surface antigen (HBsAg) positive renal transplant recipients who transplanted at the KyungHee University Medical Center during the period of January 1992 to July 2000. All these patients have no clinical sign or symptom of chronic hepatitis at the time of transplantation. Mean follow up period was 70 month (range 7-57). Three of 5 patients developed liver cirrhosis with complications during follow-up period. One patient died of fulminant hepatitis due to reactivation of HBV. The remaining one patient is free of disease till now. Four of 5 patients maintained the function of transplanted kidney and only one patient restarted hemodialysis.

PURPOSE: Macrolide-resistant Mycoplasma pneumoniae pneumonia (MPP) is characterized by prolonged fever and radiological progression despite macrolide treatment. Few studies have examined serum procalcitonin (PCT) level in children with MPP. We aimed to investigate the association of acute inflammation markers including PCT with clinical parameters in children with MPP. METHODS: A total of 147 children were recruited. The diagnosis of MPP relied on serial measurement of IgM antibody against mycoplasma and/or polymerase chain reaction. We evaluated the relationships between C-reactive protein (CRP), PCT, and lactate dehydrogenase (LDH) levels and white blood cell (WBC) counts, and clinical severity of the disease. We used multivariate logistic regression analysis to estimate the odds ratio for prolonged fever (>3 days after admission) and hospital stay (> 6 days), comparing quintiles 2–5 of the PCT levels with the lowest quintile. RESULTS: The serum PCT and CRP levels were higher in children with fever and hospital stay than in those with fever lasting ≤ 3 days after admission and hospital stay ≤ 6 days. CRP level was higher in segmental/lobar pneumonia than in bronchopneumonia. The LDH level and WBC counts were higher in children with fever lasting for >3 days before compared to those with fever lasting for ≤ 3 days. The highest quintile of PCT levels was associated with a significantly higher risk of prolonged fever and/or hospital stay than the lowest quintile. CONCLUSION: Serum PCT and CRP levels on admission day were associated with persistent fever and longer hospitalization in children with MPP.

OBJECTIVES: Pathogenic Vibrio species are widely distributed in warm estuarine and coastal environments, and can infect humans through the consumption of raw or mishandled contaminated seafood and seawater. For this reason, the distribution of these bacteria in South Korea was investigated.METHODS: Seawater samples were collected from 145 coastal area points in the aquatic environment in which Vibrio species live. Environmental data (i.e., water temperature, salinity, turbidity, and atmospheric temperature) was collected which may help predict the distribution of the species (data not shown). Seawater samples were filtered, and incubated overnight in alkaline peptone water, at 37°C. Using species-specific polymerase chain reaction methods, screening tests were performed for the hlyA, ctxA, vvhA, and tlh genes. Clones of pathogenic Vibrio species were isolated using 3 selective plating media.RESULTS: In 2017, total seawater isolation rates for Vibrio vulnificus, Vibrio cholerae (non-pathogenic, non-O1, non-O139 serogroups), and Vibrio parahaemolyticus were 15.82%, 13.18%, 65.80%, respectively. However, in 2018 isolation rates for each were 21.81%, 19.40%, and 70.05%, respectively.CONCLUSION: The isolation rates of pathogenic Vibrio species positively correlated with the temperature of seawater and atmosphere, but negatively correlated with salinity and turbidity. From 2017 to 2018, the most frequent seawater-isolated Vibrio species were V. parahaemolyticus (68.10 %), V. vulnificus (16.54%), and non-toxigenic V. cholerae (19.58%). Comprehensive monitoring, prevention, and control efforts are needed to protect the public from pathogenic Vibrio species.

PURPOSE: Risk-taking behaviors are defined as patterns of behavior initiated during adolescence which are responsible for the majority of negative health outcomes occurring during the rest of the life. The study was to explore the relationship between the risk-taking behaviors and their predisposing factors among adolescents. METHODS: The study used a survey design with an anonymous self-report questionnaire administered to 1,076 students from first year of middle school to first year of high school in Ansan City. The questions were constructed from nine risk-taking behaviors of independent variables including smoking, alcohol, drug abuse, adaptation at school, use of computer, sexual behavior, vehicle use, suicide, school violence and eight predisposing factors of school grade, gender, academic ranking, academic achievement of the mother, socioeconomic status, living with both parents, religion of the student and the mother. The data was analysed by the statistical methods of X(2) test and Fisher's exact test. RESULTS: The study revealed that the combination of the independent variables of the risk-taking behaviors to have a close association(P<0.05) with the predisposing factors. CONCLUSION: School grades, socioeconomic status, academic rankings, final educational level of the mother and living with both parents were factors strongly correlating with risky behaviors. The role of the clinician to identify those at risk is fundamental for health maintenance long after adolescence.

PURPOSE: We investigated the menstrual features of adolescent school girls to know the characteristics of menarche and dysfunctional uterine bleeding in adolescents. METHODS: In March, 2001, 1,434 primary and middle school girls(10-15 years of age) in Ansan City were investigated for the menacheal age and several aspects of menstruation through questionnaire. RESULTS: Mean age of the total subjects were 13.0+/-1.2 years of age, and 68.4% of them experienced menarche. 32.2% experienced menarche after age 12, but 82.9% experienced it after age 13. Mixed type(regular and irregular) menstrual cycle was the most common(35.3%), and changing type(irregular to regular) was 27.6%. In changing type, the mean duration of cycle stabilization was 6.6+/-4.9 months. The most common menstrual cycle was 'within 26-30 days'(31.4%). Abnormal cycles such as 'equal or less than 20 days' and 'equal or more than 41 days' were 17.2% and 2.0%, respectively. The most common menstrual duration was '5-6 days'(44.7%). 7.6% of the subjects experienced short or long menstrual duration. Among the subjects, only 4.0% visited the hospital with menstrual problems. The visiting reasons were 'irregular menstrual cycles'(38.5%), 'dysmenorrhea'(28.2%), 'menorrhagia'(12.8%), and 'hypermenorrhea'(28.2%). CONCLUSION: Most adolescent girls in our study experienced menarche until 13 years of age and some of them got early menarche at the age of 9. Many of them had irregular or unstable menstrual cycles after menarche at any age, but only few of them visited a health care provider. We suggest the careful attention of pediatricians, parents and teachers to the early detection and proper treatment of menstrual problems in adolescent girls.
