BACKGROUND: The determination of serotype of enteroviruses is useful for the discrimination between sporadic and epidemic infections. The conventional serotyping method is time-consuming and labor-intensive. Recently, molecular method was introduced for the serotyping of enteroviruses. The aim of this study was to establish a method to isolate and analyze enteroviruses from various specimens utilizing molecular biological techniques and to determine which strains were phylogenetically related to clinical samples. METHODS: Clinical samples in this study included 164 cerebrospinal fluid (CSF), 136 stool, 15 sera, 6 throat swab, 5 urine, and 4 sputa, which were obtained from hospitalized patients, primarily infants or children presenting symptoms of aseptic meningitis in 1998. RD cells were used for enterovirus isolation. RT-PCR was performed with RD cell lysate showing CPE. The primers 011 and 012 were used for the VP1 region, and the primers EN1 and EN2 for 5'-UTR. The nucleotide sequences of VP1 region were determined and analyzed with BLAST program. RESULTS: Among 333 samples, only 23 samples produced CPE: 17 samples at first and six samples at the second blind passage. Fifteen isolates were related to coxsackievirus B2 two to echovirus 4, three to echovirus 6, and three to echovirus 18. All 23 viral isolates displayed a nucleotide sequence identity of 80-95%, compared with the reference serotypes. However, the identity was increased up to 93-100% when the VP1 region was translated into amino acids CONCLUSIONS: Since CB2 type was 55% among enteroviral isolates, the CB2 was determined as the major causative serotype of enteroviral meningitis in 1998. CB2 type was emerged between June and July, EC4 and EC6 was limited to July, and EC18 was in August.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

BACKGROUND: An Epidemiological study was undertaken to evaluate the prevalence of E. vermicularis infestation among children in kindergartens. METHODS: A total of 247 cellotape anal swab specimens from kindergarten children in Inchon were examined for E. vermicularis eggs. Each specimen was collected in the morning. RESULTS: Out of 247 specimens from two kindergartens in Inchon, E. vermicularis eggs were detected in 168 specimens, the egg detection rate being 68.0%. The egg detection rates in boys and girls were 63.9% out of 133 children and 72.8% out of 114 children, respectively. The egg detection rate in girls was higher than that of boys. The egg detection rates by age group was 65.5%(age 3), S7.4%(age 4), 72.0%(age 5) and 75.4%(age 6), respectively. CONCLUSIONS: Enterobiasis is a cosmopolitan infection. Surveys for children of kindergartens indicate that E.vermicularis is probably the most widely distributed human helminth, its incidence varing from 59.2% to 73.8% in groups studied since pinworm infection is frequently a familial problem that infestation of the household frequently results in reinfection. Careful washing of hands and cleansing of fingernails before meals and after use of the toilet are the most practical measures, all member of family should be treated simultaneously when practicable.

5.Types of Usual Source of Care and Medication Adherence in Patients with Diabetes Mellitus
Korean Journal of Family Practice 2025;15(1):47-53
Background:
Previous studies have shown various positive associations between the usual source of care (USC) and medication adherence in chronic diseases. However, no studies specifically on patients with diabetes have been conducted in Korea. This study examined the association between the USC type and medication adherence in patients with diabetes.
Methods:
Data from the 2021 Korea Health Panel Survey were used. The final sample comprised 1,493 participants aged ≥20 years. The types of USC were categorized into three groups: no USC, place only (without a regular doctor [RD]), and RD. Medication adherence was assessed using detailed items (dose, frequency, time, and discontinuation) and a four-point Likert scale. Logistic regression analysis was conducted with adjustment for control variables.
Results:
The odds ratios (ORs) for overall medication adherence were significantly higher in the RD group at 1.66 (95% confidence interval [CI], 1.15– 2.40) than in the no-USC group. No significant difference was observed in the place-only group at 0.73 (95% CI, 0.49–1.09). The ORs for medication adherence for each item (dosage, frequency, and timing) were also significantly higher in the RD group (2.21, 1.95, and 1.67, respectively). No statistically significant differences in these parameters were observed in the place-only group.
Conclusion
The presence of an RD positively affected medication adherence in patients with diabetes, but the presence of place-only did not. These findings emphasize the importance of an RD for medication adherence.

10.Study of Adverse Effect to Preterm Labor and Fetus Development after Prenatal Psychotropic Exposure.
Korean Journal of Psychopharmacology 2014;25(3):101-106
OBJECTIVE: Psychotropic drugs use in pregnant mothers with psychiatric disorders raises issues of safety not only with the mothers but also with fetal development and the postpartum prognosis of the neonate. Several studies have reported on the harmful effects of antenatal exposure to psychotropic drugs. However, debatable disregard of the psychiatric disorder itself and issues of necessary and useful pharmacotherapy clouds the results. Hence, the purpose of this study was to retrospectively examine the association between prenatal psychotropic exposure and clinically evident fetal adverse effects. METHODS: From January 1994 to December 2011, a retrospective chart review of patients diagnosed with a major psychiatric disorder from the department of psychiatry and who also had a history of giving birth at the department of obstetrics and gynecology at Ajou University Hospital was conducted. Participants were divided into two groups: those taking psychotropic drugs during pregnancy were designated to the case group and the control group consisted of those not on psychotropics during pregnancy. Psychotropics included antidepressants, antipsychotics and benzodiazepines used in clinical dosages. Then the two groups were compared on factors such as gestational age, the offspring's birth weight, bitemporal diameter, and Apgar scores. After then, we analyzed relatively risk potential to the preterm labor in such variables (old age pregnancy, gestational diabetes, gestational hypertension and exposure psychotropics in pregnancy). T-test and logistic regression analysis of the data was performed. RESULTS: Demographic and clinical characteristics did not differ significantly between the groups. Also, there was no significant difference in gestational age, birth weight, bitemporal diameter and Apgar scores between the exposure and non-exposure groups. There was no significant relationship between psychotropic exposure during pregnancy, old age pregnancy, gestational diabetes and preterm labor. However, the relationship between gestational hypertension and preterm labor was significant. CONCLUSION: Psychotropic drugs are considered as significant clinical treatment options to control symptoms of psychiatric disorders during pregnancy. In the clinical setting there was no statistically significant relationship between psychotropic exposure and gestational age on fetal development. However the retrospective nature of the study limits the interpretation of the data and constant close monitoring of pregnant patients in the clinical setting is advised.
