Tailgut cyst of retrorectal space is uncommon and its classification and prognosis are unclear. The lesion usually consists of a multiloculated cyst lined by squamous, transitional, and glandular epithelium. Disorganized fascicles of smooth muscle may be seen in the wall. Glomus coccygeum, normally located at the tip of coccyx, is incidentally discovered in the presacral mass including tailgut cyst. We report a case of tailgut cyst in a 35 year old female who had internal hemorrhoid and intermittent anal pain for 3 years. Pelvic computerized tomography revealed a 3x2 cm sized mass in the presacral area. The mass was multicystic and lined by squamous, transitional, and peudostratified ciliated columnar epithelium with inflammatory cells and scattered smooth muscle in the wall. Dermal adnexal structures were not present, which excluded dermoid cyst. A glomus body was identified in the surrounding soft tissue.

BACKGROUND: The 5-hydroxytryptamine type 3 (5-HT3) receptor is a member of the Cys-loop superfamily of ligand-gated ion channels (LGICs) and modulated by pharmacologic relevant concentrations of volatile anesthetics or n-alcohols like most receptors of LGICs. The goal of this study was to reveal whether the site-directed single mutations of E-106, F-107 and R-222 in 5-HT3 receptor may affect the anesthetic modulation of halothane known as positive modulator. METHODS: The wild-type and mutant receptors, E106D, F107Y, R222F, R222V, were expressed in Xenopus Laevis oocytes and receptor function was assessed using two electrode voltage clamp techniques. RESULTS: E106D, F107Y, R222F, R222V mutant 5-HT3A receptors were functionally expressed. F107Y mutant 5-HT3A receptors displayed decreased sensitivity to 5-HT compared to the wild type 5-HT3A receptor (P < 0.05). Halothane showed positive modulation in both wild and F107Y mutant 5-HT3A receptors but F107Y mutant 5-HT3 receptor showed greater enhancing modulation comparing to wild-type receptor. Meanwhile, R222F and R222V mutant 5-HT3 receptor lost positive modulation with 1 and 2 MAC of halothane. Most interestingly, positive modulation by halothane was converted into negative modulation in E106D mutant 5-HT3A receptor. CONCLUSIONS: The present study implicate the amino acid residues known for agonist binding and linking agonist binding to channel gating might also have important role for anesthetic modulation in 5-HT3A receptor.

OBJECTIVE: Our purpose was to establish whether FHR recording tape and telemetry system at home interpreted by remote telemedicine link is comparable to interpretation at hospital in a high-risk patient population. Patients and METHODS: Twenty women whose pregnancy was suspected as high risk were entered to study. All pregnancies were at term(7 at 38th weeks, 7 at 39th weeks, 6 at 40th weeks). Remote FHR monitoring at hospital was made for consecutive 6 days, using FHR-telemetry system at home which already developed and used by authors from 1991. Patients recorded FHR sound using recording tape for 5 days. On the 5th day, real-time transmitting of FHR sound to the hospital was also done via telephone lines after recording of FHR sound. On the 6th day, FHR test(NST) was performed at hospital. The signal loss(%), baseline FHR(bpm), and FHR variability were compared using computerized FHR analysis system(HYFM-I) after re-play of 5-days recording tapes at hospital with real-time transmitting data and in-hospital FHR test results. RESULTS: The signal loss was highest with real-time transmiting data when comparing with in-hospital FHR analysis. No significant differences were observed among 5-days data of FHR recording tapes. CONCLUSIONS: Frequent antenatal visit of high-risk pregnancy patients were in diHuities of their pregnancy outcomes. And many rural areas of our country are without adequate access to basic maternity services. From this point of view, a fetal telemedicine service is needed, and in fact, technically and clinically feasible. Our demonstration suggests that such a service reduces the need for hospital visit of high risk pregnancy women. Further evaluation in a variety of clinical settings is now indicated, along with cost-benefit analysis.

PURPOSE: It was reported that Captopril (angiotensin converting enzyme inhibitor) had an effect to reduce the pneumonitis and pulmonary fibrosis induced by radiation in rat. We performed this study to investigate the radioprotective effect and mechanism of Captopril. METHODS AND MATERIALS: The comparison was made between the radiation only group and the combined Captopril and radiation group by examining histopathologic findings and immunohistochemical stains (TNFalpha and TGFbeta1) at 2 and 8 weeks after irradiation. Each group has 8 to 10 rats (Sprague-Dawley). 12.5 Gy of X-ray was irradiated to the left hemithorax in a single fraction. Captopril (50 mg/kg/d) mixed with water was given per oral and continuously from 1 week prior to irradiation up to 8th week of the experiment. RESULT: In the combined Captopril and radiation group, the histopathologic changes which were hemorrhage into alveolar space, changes of alveolar epithelium, bronchial epithelium and blood vessels, and perivascular edema were less severe than in the radisation only group at 2 weeks. At 8 weeks, the alveolar epithelial changes and perivascular edema were less prominant in the combined Captopril and radiation group. At 2 weeks, the TNFalpha expression of the combined Captopril and radiation group was markedly decreased at the alveolar epithelium (p<0.01), lymphoid tissue (p=0.06) and the macrophage of alveolar space (p<0.01) compared with the radiation only group. Furthermore the TGFbeta1 expression was significantly prominant at the alveolar epithelium (p<0.02) and the macrophage in alveolar space (p< 0.02). At 8 weeks, the expression of TNFalpha and TGFbeta1 of most sites, except TGFbeta1 of the macrophage of alveolar space (p=0.09), showed no significant difference between 2 groups. CONCLUSION: This study revealed that early lung damage induced by irradiation was reduced with the addition of Captopril in the latent and early pneumonitis phase. The expression of TNFalpha and TGFbeta1 at 2 weeks and TGFbeta1 at 8 weeks was further decreased in the combined Captopril and radiation group than the radiation only group. From these results, it may be concluded that the proinflammatoy cytokine (TNFalpha) and fibrogenic cytokine (TGFbeta1) probably play the role of the radioprotective mechanism in Captopril.

PURPOSE: The purpose of this study was done to investigate the effects of oral care using 0.12% chlorhexidine and saline solution on oral status, incidence of oral pathogens and pneumonia among children who had cardiac surgery. METHODS: The study participants were 84 children who underwent cardiac surgery and were admitted to the SICU of a university hospital. Oral care was provided with 0.12% chlorhexidine to the experimental group (n=43) and with saline solution to the control group (n=41), 3 times a day for 3 days. Before and after the intervention, the oral status, oral swab culture, and CPIS were checked. RESULTS: There was no significant difference in oral status score between the two groups. The incidence of oral pathogens in the experimental group was significantly lower than that of the control group (t=-5.780, p<.001). The CPIS in experimental group was significantly lower than that of control group (t=-3.665, p<.001). CONCLUSION: The oral care with 0.12% Chlorhexidine is more effective than with only saline solution for reducing incidence of oral pathogens and pneumonia.

Journal of Korean Academy of Psychiatric and Mental Health Nursing 2022;31(4):403-414
Purpose:
This study is to understand the experiences of people with serious mental illness following adjustment to independent living.
Methods:
Aphenomenological research approach was used. Research participants were recruited from community psychiatric rehabilitation centers where they received the support for successfully independent living in the community. In-depth interviews were conducted with a total of 20 research participants from September 2019 to August 2021. The collected data were analyzed using the phenomenological analysis method previously described by Giorgi.
Results:
Four major themes emerged from our analysis: (1) feeling free in everyday life changed when they started living independently; (2) being the owner of my life; (3) feeling surrounded by barriers at the start of independent living; and (4) required efforts and support for fully living independently.
Conclusion
Our study findings encourage fundamental understanding of benefits and difficulties in adjusting to independent living and the adjustment process among people with serious mental illness through in-depth analysis of their experiences. It is necessary to conduct further studies to develop interventions to support people with serious mental illness once they start living independently and instruments to measure their independence.

Background:
According to the Diabetes Fact Sheet published by the Korean Diabetes Association, as of 2020, one in six adults (16.7%) over the age of 30 were diagnosed with diabetes. In this rapidly increasing prevalence of diabetes in Korea, the severity of diabetes to raise awareness of the importance of awareness, early detection, and active management. A public diabetes awareness survey was conducted in 2022 and 2023, and the survey contents by year were compared and presented.
Methods:
This survey was a structured online questionnaire conducted in October 2023, targeting a total of 1,000 adult men and women aged 20 or older nationwide through population proportional allocation according to age, sex, and residential area.
Results:
The survey results indicated that 91.4% of respondents perceive diabetes as a serious disease, and 68.3% of those without a diabetes diagnosis have expressed concerns about diabetes or hyperglycemia. However, awareness of ‘prediabetes’ and ‘glycated hemoglobin’ was only 61.3% and 38.1%, respectively. On the other hand, only one-third of the respondents reported maintaining an appropriate weight and waist circumference, eating regular meals, and engaging in regular exercise. While awareness and perceived necessity of insulin injections were high, the willingness to undergo injection therapy was only about 50%, indicating a need to provide information on the benefits of insulin therapy and its positive impact on quality of life.
Conclusion
Therefore, raising awareness about the severity of diabetes, along with education and intervention, is necessary to facilitate early detection and proactive management of diabetes.

Journal of the Korean Radiological Society 2021;82(5):1274-1280
Acute necrotizing encephalopathy (ANE) is a rare but distinctive type of influenza-associated encephalopathy characterized by symmetric multiple lesions with an invariable thalamic involvement. Although the exact pathogenesis of ANE remains unclear, the most prevalent hypothesis is the “cytokine storm,” which results in blood-brain-barrier breakdown. We present the case of a 10-year-old boy with fulminant ANE confirmed with serial MRI studies, including diffusion-weighted imaging and susceptibility-weighted imaging. A comparison of these serial images demonstrated detailed and longitudinal changes in MRI findings during the clinical course corresponding to pathophysiological changes. Our case clarifies the pathogenesis of ANE brain lesions using serial imaging studies and suggests that early immunomodulatory therapy reduces brain damage.
