There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

Background:
Although the older adult population in Korea is growing, few studies have investigated the profile of late-onset vitiligo (onset at 50 years of age or above) to date.
Objective:
The present study aimed to describe the clinical characteristics and course of patients with late-onset vitiligo in Korea.
Methods:
The present single-center retrospective study included 132 patients with late-onset vitiligo from January 1, 2009 to November 30, 2022. We analyzed patient demographics and vitiligo characteristics. Further, we evaluated the progress of late-onset vitiligo using the Vitiligo Area Severity Index (VASI) score.
Results:
The study included more females (n=83, 62.9%) than males (n=49, 37.1%), with an average age of onset 60.9±7.4 years. The average duration of the disease before presentation was 15.0±27.3 months. A family history of vitiligo was identified in eight patients (6.1%), and seven patients (5.3%) had associated autoimmune diseases.Acrofacial vitiligo was the most common type (n=56, 43.1%), and the head and neck area were the commonly affected site at disease onset (n=93, 70.5%). The Koebner phenomenon was observed in seven patients (5.3%), and chemical-induced vitiligo was suspected in three patients (2.3%). Treatment was administered to 131 patients (99.2%). The VASI score decreased in 93 patients (83.0%), with an average decline rate of 58.56%.
Conclusion
Late-onset vitiligo tends to be of the acrofacial vitiligo subtype in the Korean population. Patients demonstrated a strong desire to treat vitiligo, and treatment response was promising. Further larger-scale studies to elucidate the characteristics and progression of late-onset vitiligo may be needed.

Journal of the Korean Neurological Association 2001;19(2):102-109
BACKGROUND: Ropinirole is a non-ergoline D2 agonist which has a highly selective affinity to D2 receptor. The aim of this study was to evaluate the efficacy and safety of ropinirole in the treatment of Parkinson's disease (PD). METHODS: Seventy-six cases with PD (Hoehn and Yahr stage II to IV) were included in this trial. Each patient was randomly allocated to receive either ropinirole (n=37) or bromocriptine (n=39) over a 16-week period. All subjects were not optimally controlled on levodopa due to motor fluctuations. The response rate was defined as the percentage of patients who had at least 20% reduction of levodopa doses. The clinical status was also assessed using the Unified Parkinson's Disease Rating Scale (UPDRS), Clinical Global Impression (CGI), and reduction of off durations. RESULTS: The end-point analysis, on an intention-to-treat basis, revealed significantly higher response rate in the ropinirole group compared with the bromocriptine group (odds ratio 2.995, 95% C.I. (1.157, 7.751)). A statistically significant improvement in CGI was also observed in the ropinirole group (p=0.046). The mean off duration was significantly reduced in the ropinirole group (p=0.0001). Other parameters using the UPDRS motor score or off duration did not show significant differences between the two groups. The overall incidence of adverse effects was not significantly different between the two groups. The most common side effects were dizziness, dyskinesia, and nausea/vomiting. No subjects were withdrawn from the study due to side effects. CONCLUSION: Ropinirole is a safe and well-tolerated drug and provides superior overall efficacy compared with bromocriptine as an adjunct to levodopa. (J Korean Neurol Assoc 19(2):102~109, 2001)

PURPOSE: This study was designed to describe the burnout experiences of nurses counseling people living with HIV/AIDS (PLWHA) in hospital-based counseling services in Korea. METHODS: A qualitative research technique with focus group interviews was used and the data were collected in 2012. Participants were 13 counseling nurses from 16 medical hospitals in South Korea who had worked full-time for more than six months as a counseling nurse for PLWHA. The 13 nurses made up 68.4% of all 19 official HIV counseling nurses in South Korea. Data were collected using focus group interviews and analyzed with the content analysis methodology of Downe-Wamboldt. RESULTS: Burnout experience of counseling nurses for PLWHA was analyzed for two domains-causes of, and effects of burnout. Each domain was classified into three categories; personal, job-related, and relationships. Further 17 sub-categories and 47 concepts were discovered. CONCLUSION: In this study various causes and effects of burnout experienced by nurses counseling PLWHA were identified. These findings can be used in developing effective strategies for nurses, administrators, and health policy makers to solve the burnout of counseling nurses. Further research is required to develop detailed and practical job description for nurses counseling PLWHA.

Toxoplasma gondii is an obligate intracellular protozoan parasite, which invades a wide range of hosts including humans. The exact mechanisms involved in its invasion are not fully understood. This study focused on the roles of Ca2+ in host cell invasion and in T. gondii replication. We examined the invasion and replication of T. gondii pretreated with several calcium modulators, the conoid extrusion of tachyzoites. Calmodulin localization in T. gondii were observed using the immunogold method, and Ca2+ levels in tachyzoites by confocal microscopy. In light microscopic observation, tachyzoites co-treated with A23187 and EGTA showed that host cell invasion and intracellular replication were decreased. The invasion of tachyzoites was slightly inhibited by the Ca2+ channel blockers, bepridil and verapamil, and by the calmodulin antagonist, calmidazolium. We observed that calcium saline containing A23187 induced the extrusion of tachyzoite conoid. By immunoelectron microscopy, gold particles bound to anti-calmodulin or anti-actin mAb, were found to be localized on the anterior portion of tachyzoites. Remarkably reduced intracellular Ca2+ was observed in tachyzoites treated with BAPTA/AM by confocal microscopy. These results suggest that host cell invasion and the intracellular replication of T. gondii tachyzoites are inhibited by the calcium ionophore, A23187, and by the extracellular calcium chelator, EGTA.
