Over the past 30 years, there has been an increase in the incidence of multifetal pregna-ncies, primarily because of the introduction of ovarian stimulants for ovulation induction and assisted reproductive technology ( ART ) in infertile patients. It is well established that multifetal pregnancies are associated with an increased frequency of the maternal complications and gre-ater perinatal morbidity and mortyality. The adverse outcome of multifetal pregnancies is dire-ctly proportional to the number of fetuses, primarily as an consequence of prterm delivery. Re-duction in the number of fetuses in multifetal pregnancies has been proposed as a way to impr-ove the perinatal outcome in this situation. Therefore, selective fetal reduction ( SFR ) is sugges-ted as a therapeutic option for continuation of pregnancy with fetuses mature enough to survi-ve. In this paper, we report our infertility clinic experiences with 6 patients who carried mult- ifetal pregnancies including 1 quintuplet, 1 quadruplet, and 4 triplets. from January, 1991 to May, 1996, transabdominal SFR was accomplished by fetal intrathoracic KCl injection at 9~10 weeks of gestation. After the prcedure, 4 patients remained as twin pregnancies, and 2 patients as single pregnancy. There have been 3 sets of twin deliveries and the 2 sets of single delivery. One case was aborted. Two patients were delivered after 37 weeks of gestation, 2 patients were at 35 weeks, and 1 patient at 24 weeks. All babies have been healthy after birth in patients after 35 weeks gestation. There was no fetal anomaly related to the procedure in the 6 cases. We concluded that transabdominal SFR is a rather safe and useful procedure that may improve the outcome of multifetal pregnancies.

PURPOSE: This study aimed to develop and test a structural model for sleep quality in female shift work nurses. The hypothetical model was constructed on the basis of Spielman's 3P model of insomnia and previous research related to the sleep quality of shift nurses. METHODS: This cross-sectional study used structural equation modeling and recruited 285 female shift work nurses from four general and university hospitals with over 300 beds located in C and J cities in Gyeongsangnamdo. Data were collected from September 27 to October 20, 2016, and then analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling. The study used SPSS/Win 18.0 and AMOS 18.0 in processing the data. RESULTS: The final model showed good fit to the empirical data: χ2/df=2.19, SRMR=.07, RMSEA=.07, AGFI=.85, TLI=.91, GFI=.93, GFI=.89, NFI=.87. The factors that influenced sleep quality were sleep hygiene (β=.32), perceived shift work status (β=−.16), stress response (β=.16), shift work experience (β=.15), perceived health status (β=−.14), and circadian rhythm (β=−.13) explaining 36.0% of the variance. CONCLUSION: The model of sleep quality of the shift work nurses constructed in this study is recommended as a model to understand and predict the sleep quality of shift work nurses. The results suggest that strategies for improving the sleep quality of shift work nurses should focus on sleep hygiene, perceived health status, stress response, circadian rhythm, perceived shift work status, and shift work experience.

PURPOSE: To evaluate the outcome of coronary lesions for efficacy of dexamethasone therapy after additional immunoglobulin(IVIG) retreated in initial IVIG-resistant Kawasaki disease(KD). METHODS: Retrospective studies were performed on 438 cases of KD treated with one or two episode of high-dose IVIG and 24 cases with dexamethasone therapy after additional immunoglobulin(IVIG) retreated in initial IVIG-resistant Kawasaki disease(KD) at this hospital from June 2000 to January 2004. 2D echocardiogram was done at admission, 2 months later and every 2 or 3 months when coronary lesion had improved more than 2 months later. RESULTS: In 108(24.7%) of 438 cases with IVIG therapy only, 10(41.7%) of 24 cases with dexamethasone therapy after additional immunoglobulin(IVIG) retreated in initial IVIG-resistant Kawasaki disease(KD), coronary abnormality had been shown by initial 2D-echocardiogram examined at acute stage. In 10(2.3%) of 438 patients with IVIG therapy only, and in 3(12.5%) of 24 cases with additional IVIG retreatment, coronary lesions were still remained at follow-up echocardiogram. Even though it had tendency to increase the coronary lesions in the group with dexamethasone therapy after additional immunoglobulin(IVIG) retreated in initial IVIG-resistant Kawasaki disease(KD), there was no significant differences about the incidence of coronary lesions between two groups. There was no significant differences in age, sex, and other clinical findings between two groups. CONCLUSION: The combination therapy with high doses of IVIG and aspirin in KD is the standard treatment but not always effective. The dexamethasone therapy may be another treatment of choice after additional immunoglobulin(IVIG) retreated in IVIG- resistant Kawasaki disease(KD).

Objective: The number of patients suffering from dysphagia is increasing in line with societal aging. However, preparing dysphagia diets at home or in welfare facilities is challenging due to the lack of commercially specifically designed products. The thickening agents used to prepare dysphagia meals can be difficult due to changes in viscosity and homogenization. Therefore, this study was performed to prepare dysphagia meals using commercially available foods following the classification system outlined by the International Dysphagia Diet Standardization Initiative (IDDSI). Methods: Commercial foods were categorized as main dishes, side dishes, and snacks. Selected foods were ground or minced, and 1-3 g of thickening agent was added. Following the IDDSI framework, fork flowability, spoon tilt, and gravity flow tests were conducted using a syringe, and based on these evaluations, texture-modified foods were classified as general, minced, ground, or liquid foods. Results: Commercial foods used in the experiment could be used in IDDSI Level 2-7 dysphagia diets after adjusting their structures. Food size and viscosities were appropriately controlled, and an usage manual was developed. Conclusion This study successfully demonstrated the easy incorporation of commercial food products into the dysphagia diets for personal care and welfare facilities. By adopting the described approach, dysphagia patients could be provided various meal options with improved service. In addition, this study suggests possibilities for developing and producing diverse products designed specifically for dysphagia patients.

A balanced insertion of a parent may produce normal or carrier offsprings, spontaneous abortions, and chromosomally unbalanced offsprings. This is a rare report of duplication of chromosome 10q22->q24 which has arisen through the segregation of a balanced direct insertion. The partial trisomy 10q is a specific syndrome of mental retardation and malformation characterized by psychomotor delay, growth restriction, distinctive dysmorphic appearances, and, in some cases, cardiac, renal, and ocular abnormalities. We have experienced a case of partial trisomy 10q from maternal balanced insertion, which was prenatally showed severe fetal growth restriction and oligohydramnios, and present it with a brief review of literatures.

PURPOSE: Henoch-Schonlein purpura(HSP) nephritis has been reported to vary from 25 to 50% among HSP patients and is a common cause of chronic glomerulonephritis in children. In our study, we evaluated the distribution and the association of the Insertion/Deletion(I/D) polymorphism of angiotensin converting enzyme(ACE) gene with clinical manifestations, particularly proteinuria in children with HSP nephritis, compared with that in HSP. METHODS: ACE gene polymorphism was determined in children with HSP nephritis(n=33) and HSP(n=28) who were diagnosed in Busan Paik hospital from January 1996 to June 2001. The I/D polymorphism of ACE gene was determined by PCR amplication of genomic DNA. RESULTS: The ACE I/D genotype frequency was DD : 25%, ID : 50%, II : 25% in HSP and DD : 24 %, ID : 46%, II : 30% in HSP nephritis, there was no significant difference in the genotype and allele frequencies between two groups. When statistical analysis was done according to the presence of D allele, the amount of 24-hour urinary protein excretion and the incidence of moderate to heavy proteinuria(>500 mg/m2/day) at onset and last follow-up were higher in DD/ID genotype than in those in II genotype, but these differences were not statistically significant. CONCLUSION: We suggest a lack of association between I/D polymorphism of ACE gene and clinical manifestations in children with HSP nephritis. However, further follow-up studies based on a sufficient number of patients and long term follow up periods are necessary to confirm the role of I/D polymorphism of ACE gene in children with HSP nephritis.

OBJECTIVE: To delineate the role of antidiuretic hormone (ADH) in relation to nocturnal polyuria, and to identify the factors influencing on the diurnal antidiuretic hormone level. METHOD: The ADH was measured by radioimmuoassay at daytime (2:00 PM) and at nighttime (2:00 AM) with nocturnal polyuria group (11) and without nocturnal polyuria group (8). Urine volume, serum osmolarity, urine osmolarity, and blood pressure were also measured at the same time. RESULTS: 1) The ADH at 2:00 AM did not increase in nocturnal polyuria group, although it increased in no-symptom group. 2) There was a statistically significant correlation between wheelchair ambulation time and daytime ADH level. 3) The difference of ADH level between daytime and nighttime showed decrease in orthostatic hypotension group. CONCLUSION: There was relationship between nocturnal polyuria and diurnal variation of ADH level. The ADH concentration seems to be influenced by the postural factors and sympathetic factors.
