Purpose: This study investigated the factors that influence depression in adolescents diagnosed with asthma in South Korea, providing basic data supporting efforts to improve adolescents' mental health. Methods: Multiple regression analysis was conducted on 4,020 subjects who had been diagnosed with lifelong asthma among the 57,303 respondents to the 15th Korea Youth Risk Behaviour Web-Based Survey from 2019. Results: The participants were more likely to have depression if they were female, in middle school, their academic achievement was poor, they were drinkers or smokers, if they felt a very high amount of stress, and if they experienced very inadequate recovery from fatigue. Adolescents with asthma were 9.00 times more likely to experience depression when they felt a very high amount of stress (95% confidence interval [CI]= 5.51-14.69, p<.001) than when they felt no stress. Conclusion Given these factors, measures to improve the mental health of adolescents should be developed and expanded, especially to decrease their stress levels. A separate program that is different from the school's regular health curriculum should be developed to manage the stress levels of adolescents with asthma, such as an after-school program or a program conducted at a local community centre.

Purpose: The purpose of this study is to evaluate the usefulness of individualized metabolic surgery score for Korean patients in determining bariatric surgical procedures. Materials and Methods: A total of 135 patients with type 2 diabetes mellitus who underwent sleeve gastrectomy (n=19) or Roux-en-Y gastric bypass (n=116) at our institute with a 1-year follow up were analyzed for the predictive power of diabetes remission using the individualized metabolic surgery scoring system. Results: At the postoperative follow-up of 1 year, the remission of type 2 diabetes mellitus (HbA1C＜6.5%, off medications) was achieved in 88 (65.2%) patients. The remission rates showed no significant differences between patients who underwent sleeve gastrectomy and Roux-en-Y gastric bypass (63.2% versus 65.5%; P=0.84), regardless of the severity of type 2 diabetes mellitus. Although there was no statistically significant difference in the remission rate according to the bariatric surgery procedures (P＞0.99 in mild, P=0.11 in moderate, P＞0.99 in severe IMS score), remission rates were higher in moderate severity patients who underwent Roux-en-Y gastric bypass than in those who underwent sleeve gastrectomy (69.7% versus 37.5%). Conclusion The remission rates after bariatric surgery procedures were similar to that of the previously reported study. Despite the limitations of our data, the individualized metabolic surgery score can be used as a complement to other scoring systems in Korean patients.

In treating young women for gestational trophoblastic tumor ( G.T.T. ), all efforts are made to preserve fertility and hysterectomy is avoided unless absolutely essential. However, in some cases the operation may be lifesaving. During the last 20 years among the 310 cases of G.T.T. treated at Il Sin Christian Hospital, there were 3 cases in which hysterectomy was avoided by the excision of a localized uterine lesion thus preserving fertility.

Anterior clinoid process is a small bony structure but it is very important regarding its location and relationships with neighboring neurovascular, dural, and bony structures. Removal of this process has been used in various modification of standard pterional approach. The authors have speculated how much expansion of operative window could be obtained with anterior clinoidectomy, so we measured the lengths of optic nerve, internal carotid artery, and the length and width of optico-carotid triangle(OCT) before and after extradural anterior clinoidectomy 17 times in 10 cadaveric heads. This procedure provided about two fold increase in the length of optic nerve and OCT, and over three fold expansion in the width of OCT. The results indicate that the addition of this relatively simple and easy procedure to standard approach makes the operative field more comfortable and safe than expected. We believe this procedure can be used routinely with or without combination of wide skull base exposure in cases of such lesions as belows: 1) lesions causing optic nerve or chiasmatic compression, 2) lesions encircling/covering the optic nerve and internal carotid artery, 3) lesions arising from or extending into the optic canal, orbital apex, and paraclinoid region, 4) suprasellar/parasellar lesions with limited operative windows(e.g. prefixed chiasm, infra-optic or subchiasmatic locations or adherence).

PMWS is a new emerging disease in swine herds worldwide. Field isolates of PCV-2, a putative major causative agent of PMWS, were isolated and genetically characterized. Viral genome of two field isolates (PC201DJ and PC201SS) from pigs showing typical PMWS was sequenced. The nucleotide sequence homology with other PCV-2 isolates was ranging from 95% to 99% in complete viral genomic sequence. The highly conserved nonanucleotide motif of replication origin was identical to that of other PCV-2 isolates. To determine the genetic heterogeneity of PCV-2 isolates, the phylogenetic tree based on the complete genome of PCV-2 isolates were constructed. Two PCV-2 field isolates were closely related to Canadian isolates of PCV-2. PCV-2 isolated from field may have an origin of North America and is possibly originated from importation of breeding stocks. The result indicates that although the genome of PCV-2 is relatively stable in general, minor genetic variations exist among PCV-2 isolates from the different geographic locations. These differences of viral genome might have an important implication for genetic characteristics of PCV-2 infection. Three major immunorelevant epitopes of capsid protein showed variations in amino acid sequences. Also, the variance of amino acid sequence in antigenic epitope existed between two Korean PCV-2 isolates.

Laparoscopic sleeve gastrectomy (LSG) has become a standalone primary procedure as a bariatric metabolic surgery since the early 2000s. The overall complication rate of LSG is reported to range from 2% to 15%. Staple line leakage (SLL) remains a major adverse event and occurs in approximately 1%–6% of patients. Choosing the optimal treatment modality is a complex process. Clinicians must understand that nutritional support and drainage of fluid collection are essential for initial management. Conservative endoscopic management and sufficient drainage can resolve approximately 70% of SLLs. Endoscopic management of bariatric complications has been rapidly evolving in recent years and can be considered in all patients who are hemodynamically stable. We will review the available endoscopic management techniques, including stent placement (self-expanding stents and bariatric-specific stents), clipping, tissue sealant application, and internal drainage (double-pigtail stents [DPS] placement, endoscopic vacuum therapy, and septotomy). Stent placement remains the mainstream treatment for SLLs. However, healing with stents requires multiple sessions/stents and a long course of recovery. Endoscopic internal drainage is gaining popularity and has the potential to be a superior method. The importance of early intervention and combined endoscopic methods should be recognized.

Cesarean hysterectomy is associated with high risks of severe blood loss, postoperative complication, and maternal morbidity. This study was undertaken to identify the risk factors of cesarean hysterectomy and to reduce the postoperative complications and maternal morbidity. There were 6,362 deliveries between January 1992 and December 1996 at department of obstetrics and gynecology, Inchon Christian Hospital. 1'he results of this study were as follows, 15 cases of cesarean hysterectomy were performed during this period. Cesarean hysterectomy was performed in 10 cases (0.32 %) among 3178 cesarean deliveries and in 5 cases (0.16 %) among 3184 vaginal deliveries. The incidence of cesarean hysterectomy was 0.24 % (15/6,362). The age of patients ranged from 24 to 38 years old. The maternal mortality and morbidity were 0 % (0/15) and 86.7% (13/15), respectively. Indications for cesarean hysterectomy were uterine atony (53.3 %), uterine myoma with pregnancy (20.0 %), placenta accreta and/or increta(20.0 %), and placenta previa (6.7 %) in orders. The associated risk factors of cesarean hysterectomy were prior cesarean delivery (46.7 %) and placenta previa (6.7 %). The postoperative complications were anemia (60.0%), febrile morbidity (13.3 %), paralytic ileus (6.7 %), and wound disruption (6.7 %). We concluded that risk factors of cesarean hysterectomy were cesarean delivery, prior cesarean delivery, uterine myoma with pregnancy, placenta accreta and/or increta, and placenta previa and that sufficient fresh blood and careful prenatal care were needed in risk group of postpartum bleeding.

This study was conducted to investigate tiamulin (TML) residues in the edible tissues of orally dosed broiler chickens and to re-establish the withdrawal time (WT). Thirty-six healthy Ross broiler chickens were administered 0.5 (TML-1) and 2.5 kg (TML-2) per ton feed, respectively, of the drug containing TML 78 g/kg for 10 days. Twenty-four tissue samples were collected from 6 chickens in each of the TML-1 and TML-2 groups on 0, 1, 3, and 5 days after drug administration, respectively. The residual concentrations of TML were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The correlation coefficient of the calibration curves was 0.9978 to 0.9998, and the limits of detection and the limits of quantification (LOQ) were in the range of 0.03 to 0.06, and 0.1 to 0.2 µg/kg, respectively. Recoveries ranged between 89.0% to 116.7%, and the coefficients of variation were less than 13.9%. After the drug administration, TML in the TML-1 and TML-2 groups was detected above the LOQ in 1 and 6 samples of liver, respectively, at day 0, and in 1 liver sample from both groups on day one. At 3 days after administration, TML was detected below the LOQ in all samples of TML-1 and TML-2. The calculated WT of TML in both TML-1 and TML-2 using the WT calculation program WT 1.4 was 0 days. In conclusion, the developed analytical method is suitable for detection, and the calculated WT of TML in poultry edible tissues is shorter than the current recommended WT of 7 days for TML in broiler chickens.

PURPOSE: The in vitro dissolution of intrahepatic stones was evaluated using the various solvent mixtures. MATERIALS AND METHODS: Sixty four intrahepatic stones from 16 patients were used. Four kinds of solvent mixtures(No. 1 = basic buffer + EDTA, No. 2=1 + Sulfobetain-12, No. 3=2 + N-acetylcysteine, No. 4=3 + urea) were used. Dissolution rates were determined by measuring the weight loss of stones after 6, 12, 24, 48 hours incubation periods, respectively. RESULTS: The highest dissolution rates in dissolving intrahepatic stones were achieved with No. 4 solvent mixture(1% W/V EDTA/80mM, Sulfobetain-12/1 M, urea, pH 9.5). CONCLUSION: lntrahepatic stones could be largely dissolved up to about 70% of their initial weight after 48 hours incubation period in vitro.
