PURPOSE: The effect of surfactant treatment on inflammatory cell populations has not been determined. I evaluated the effect of surfactant treatment on a number and distribution of inflammatory cells in bronchoalveolar lavage fluid(BALF) from the preterm infants who were dependent on mechanical ventilation over the 1st week of life. METHODS: This study included 8 preterm infants with respiratory distress syndrome(RDS) who received surfactant(Exosurf, 67.5mg/kg Dipalmitoyl phosphatidylcholine(DPPC) with a volume of 5 ml/kg, single dose)on their first day of life and 7 preterm infants of similar severity who did not. BALFs were collected on days 2, 3, 5, and 7 after birth. Cell counts were performed from the obtained BALFs, then they were applied to cytospin and Wright stain, and the differentials were calculated on 200 cells. RESULTS: Surfactant treatment had no significant effect on the number of BALF white cells on days 2-7. Polymorphonuclear cell numbers were not different in both groups on days 2 7. Macrophage cell numbers were higher overall in surfactant treated babies compared to those in untreated babies on days 2-7(P<0.05). CONCLUSION: Surfactant treatment appeared to accelerate the appearance of macrophages in BALF.

There are 3 basic methods for surgical treatment of axillary osmidrosis; 1) method that removes only subcutaneous cellular tissue without removing skin 2) method that removes skin and subcutaneous cellular tissue en bloc, and 3) method that partially removes skin and subcutaneous cellular en bloc as well as removing the subcutaneous cellular tissue of the adjacent region. We studied the results of partial removal of the skin and subcutaneous cellular tissue en bloc, as well as the removal of subcutaneous cellular tissue of the adjacent region to compare the results of the bipedicled flap with the graft conversion method. There was no difference between two methods in results and complication rates. There are 3 advantage to this procedure. First, about 70-80% of apocrine glands were centrally distributed among the axillary hairbearing region therefore, resection of the central portion of axillary hair distribution area is important for good result. Second, the preservation of the subdermal plexus with careful excision of adjacent underlying subcutaneous tissue under the aid of the magnifying surgical loupe, is important for good wound healing. Third, the central excision of the axillary hair distribution area provides good exploration for undermining and defatting of the undersurface of the adjacent area, therefore it tooks a shorter operation time.

BACKGROUND: Alpha-blocker can result in falling and fractures because of adverse effect such as orthostatic hypotension due to vasodilatory effect. We investigated the association between the alpha-blocker and the risk of osteoporotic hip fractures using a nationwide claim database. METHODS: We identified 1,051,651 men 65 years of age or older who had prescription records of alpha-blocker from nationwide medical claim database, from 2007 to 2012. Alpha-blockers were classified as non-specific general (NSG), non-specific slow-release (NSSR), uro-specific general (USG), and uro-specific slow release (USSR). RESULTS: Total of 6,553 hip fractures were observed. The incidences of hip fracture within 1 year were higher than those of the reference periods in all type of alpha-blocker. Hazard ratio peaked at early period of alpha-blocker, and decreased with time, regardless of type of alpha-blocker. CONCLUSIONS: Use of alpha-blocker is associated with increased risk of hip fracture, especially in early use.

Journal of Preventive Medicine and Public Health 2021;54(4):284-292
Objectives:
Low bone density (LBD) in the postmenopausal period has long been a pervasive public health concern; however, the association between parity and LBD has yet to be fully elucidated. Thus, we investigated the association between parity and LBD in postmenopausal Korean women.
Methods:
This study used baseline data from 1287 Korean postmenopausal women aged 40 years or older enrolled in the Cardiovascular and Metabolic Diseases Etiology Research Center community-based cohort study conducted in Korea from 2013 to 2017. The main exposure was parity (nullipara, 1, 2, 3+). The main outcome was LBD, including osteopenia and osteoporosis, based on bone mineral density measured using quantitative computed tomography of the lumbar spine (L1-2).
Results:
The mean age of participants was 57.1 years, and the median parity was 2. Of the 1287 participants, 594 (46.2%) had osteopenia and 147 (11.4%) had osteoporosis. No significant difference in the prevalence of LBD was found between nullipara and parous women, whereas higher parity was associated with a higher risk of LBD among parous women; the adjusted odds ratio (95% confidence interval) for the presence of LBD was 1.40 (0.97 to 2.02) for a parity of 2 and 1.95 (1.23 to 3.09) for a parity of 3 relative to a parity of 1.
Conclusions
Women who have given birth multiple times may be at greater risk of bone loss after menopause; therefore, they should be a major target population for osteoporosis prevention.

Asian Oncology Nursing 2020;20(2):92-99
Purpose:
The purpose of this study was to identify the effects of repeated audiovisual information on the reduction of uncertainty and anxiety in patients undergoing thyroidectomy.
Methods:
A non-equivalent control group pretest-posttest design was used. The study included 32 patients in the experimental group and 32 in the control group. Preoperative information using video-audio media was provided two times for 5 minutes and 45 seconds each in the experimental group, while the control group only received routine care. The data collection period was from November 1, 2017 to February 23, 2018. The data were analyzed using χ² test, t test, and independent t-test with SPSS/WIN 24.0.
Results:
Significant differences were observed between the two groups in pre- and post-uncertainty scores (t = -2.06, p= .044) and anxiety scores (t = -2.06, p= .044).
Conclusion
Repeated information provided by using videoaudio media is effective as a nursing intervention to reduce uncertainty and anxiety in patients undergoing thyroidectomy.

Journal of Korean Academy of Fundamental Nursing 2024;31(1):135-146
Purpose:
This study was conducted to gain a comprehensive and in-depth understanding of infection control nurses’ burnout experiences in hospitals during the COVID-19 pandemic.
Methods:
We recruited 11 infection control nurses (ICNs) who worked in hospitals in Korea through purposive sampling. Data collected through one-to-one, in-depth interviews were transcribed and analyzed using qualitative content analysis.
Results:
Infection control nurses’ burnout experiences were categorized into five themes and 11 sub-themes. The themes were as follows: “challenges faced while playing a pivotal role in infectious disease management,” “conflict of interest prevalent inside and outside,” “physical and mental collapse,” “a long road to achieving stability in the infection control unit,” and “source of strength to endure.”
Conclusion
In light of the need to better prepare for future outbreaks of emerging infectious diseases, such as COVID-19, the findings of this study highlight the need for strategic approaches, such as developing programs to provide psychological and social support for infection control nurses, as well as establishing a well-designed system of nursing care for infectious diseases to alleviate their burnout.

Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality. Twin pregnancy and cesarean delivery are well-known risk factors for PPH. However, few studies have investigated PPH risk factors in mothers who have undergone cesarean delivery for twin pregnancies. Therefore, this study investigated the risk factors associated with severe PPH after cesarean delivery for twin pregnancies. Methods: We searched and reviewed the Korean Health Insurance Review and Assessment Service’s claims data from July 2008 to June 2021 using the code corresponding to cesarean delivery for twin pregnancy. Severe PPH was defined as hemorrhage requiring red blood cell (RBC) transfusion during the peripartum period. The risk factors associated with severe PPH were identified among the procedure and diagnosis code variables and analyzed using univariate and multivariate logistic regressions. Results: We analyzed 31,074 cesarean deliveries for twin pregnancies, and 4,892 patients who underwent cesarean deliveries for twin pregnancies and received RBC transfusions for severe PPH were included. According to the multivariate analysis, placental disorders (odds ratio, 4.50; 95% confidence interval, 4.09– 4.95; P < 0.001), general anesthesia (2.33, 2.18–2.49; P < 0.001), preeclampsia (2.20, 1.99–2.43; P < 0.001), hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome (2.12, 1.22–3.68; P = 0.008), induction failure (1.37, 1.07–1.76; P = 0.014), and hypertension (1.31, 1.18–1.44; P < 0.001) predicted severe PPH. Conclusions: Placental disorders, hypertensive disorders such as preeclampsia and HELLP syndrome, and induction failure increased the risk of severe PPH after cesarean delivery for twin pregnancy

To evaluate the long-term effect and complications of the transurethral resection of the prostate (TUR-P), we analyzed its results of 404 patients who were followed properly out of 827 patients who underwent TUR-P at Seoul National University Hospital from January 1980 to December 1993. Various pre-existing medical problems were associated in 173 patients(42.8%). The mean weight of the resected tissue was 15.6 grams and the mean operation time was 78.9 minutes with the resection amount per minute of 0.2 gm/min. Improvement of the symptoms was reported in 304 patients(75.2%) postoperatively. International prostate symptom score(IPSS) was 22.6 preoperatively, 15.4 at 3 months, 9.8 at one year and 9.3 at 3 years after TUR-P: Maximum urinary flow rate(MFR) was 9.7 ml/sec preoperatively, 15.5 at 3 months and 15.9 at one year after TUR- P The perioperative mortality rate was 0.4%, and the perioperative complications occurred in 120 patients(29.7%); including 15.8% of bleeding and 2.2% of the transurethral resection syndrome. The morbidity increased significantly with the increasing resection amount and the operation time. But not only age but also pre-existing cardiopulmonary diseases and azotemia did not influence the morbidity. Only age over 80 and preoperative urinary tract infection increased the perioperative morbidity slightly. Late complication developed in 54 patients(13.4%); urinary tract infection in 18 (4.5%), urethral stricture in 16 (4.0%), impotence in 9 (2.2%), urinary in- continence in 5 (1.2%), bladder neck contracture in 4 (1.0%) and bleeding in 2 (0.5%). Persistent voiding difficulties were reported in 100 patients(25.7%), causes were neurogenic bladder in 32, inappropriate indication of TUR-P in 32, and incomplete resection in 18 patients and so on. Repeated TUR-P was done in 16(4.0%) patients.
