2.Clinical Manifestations of Pulmonary Sequestration.
Pediatric Allergy and Respiratory Disease 2008;18(1):54-60
PURPOSE: Pulmonary sequestration is characterized by a mass of non-functioning pulmonary tissue lacking normal communication with the tracheobronchial tree and receiving an aberrant systemic arterial blood supply. Two types have been described:intralobar and extralobar. Symptoms vary from the incidental finding of a mass to recurrent bronchitis or pneumonia, chest pain and hemoptysis. In this study, we evaluated clinical features and outcomes of pulmonary sequestration. METHODS: The records of the patients diagnosed with pulmonary sequestration by thoracic computerized tomography and aortography between January 1997 and July 2007 were retrospectively reviewed. RESULTS: Fourteen patients (6 males and 8 females) with an median age of 5.5 years in children, 35 years in adults were diagnosed with pulmonary sequestration. Nine patients had clinical symptoms including recurrent respiratory infections, chest pain and hemoptysis. Six patients were symptom free. The aberrant arteries originated from the descending thoracic aorta in 12 cases, abdominal aorta in 2 cases, inferior phrenic artery in 1 case. Thirteen patients received surgical operations with open thorax in 11 patients and with video-assisted thoracotomy surgery (VATs) in 2 cases recently diagnosed. Eleven cases (84.6%) were found to be of intralobar type and 2 cases (15.4%) were of extralobar type. One patient had bilateral pulmonary sequestration. All patients with preoperative symptoms improved after surgical treatment. CONCLUSION: The patients who presented with recurrent pneumonia in the same site, hemoptysis and chest pain should be studied to rule out pulmonary sequestration.

3.The effectiveness of urokinase in treatment of pleural effusion in children.
Korean Journal of Pediatrics 2007;50(7):660-664
PURPOSE: Pleural effusion is a common complications of pediatric bacterial pneumonia. Intrapleural administration of fibrinolytic agents such as urokinase have been used in the management of complicated parapneumonic effusions. But the safety and effectiveness of intrapleural urokinase instillations in children has not been confirmed. The aim of this study is to evaluate the safety and effectiveness of intraperitoneal urokinase in children. METHODS: We reviewed a total of 29 children diagnosed as parapneumonic effusion with septation by chest CT or chest ultrasonography. We divided them into two groups. Fourteen children treated with urokinase after thoracostomy (Group A) were compared with 15 children treated only with thoracostomy (Group B). The urokinase, 3,000 IU/kg/day, was injected into the pleural cavity twice a day. RESULTS: There was no statistical difference in sex and age between the two groups. Total drainage volume during thoracostomy in group A and B was 375.5 mL and 350.0 mL, respectively. It was not statistically significant. But the amounts of pleural fluid of group A on day 1, day 2 and day 3 were 102.5 mL, 100.0 mL, and 70.0 mL respectively and those of group B on day 1, day 2 and say 3 were 120.0 mL, 50.0 mL and 15.0 mL respectively. To compare group A with group B in the amounts of drainage volume on day 1 was not statistically significant, but the amounts of drainage volumes on day 2 and day 3 in group A were statistically more significant than group B (Day 1 P=0.371, Day 2 P=0.049, Day 3 P=0.048, respectively). The duration of fever, antibiotics, thoracostomy and total hospital days. Were not statistically significant between the two groups. But the frequency of complications in Group A was statictically significantly lower than in group B. CONCLUSION: Intrapleural instillation of urokinase facilitates the drainage of loculated pleural effusions, especially during the first 3 days, and it could reduce complications, such as pleural thickening, surgical managements, re-positioning of tube and re-thoracostomy. So intrapleural urokinase injection was and effective and safe treatment of pleural effusion in children (P=0.014).

In Sprague Dawley (SD) rats, antibodies against strains of Orinentia tsutsugamushi, Kato, Karp and Gilliam, were produced in order to investigate their longevity and cross-reactivities to their corresponding homologous and heterologous antigens. By immunofluorescence assay (IFA) of IgG and IgM, it was shown that the immunity to the homologous strains persisted at a higher level (longevity of at least 34 weeks with higher IFA titers). On the other hand, the immunity to the heterologous strains persisted at a lower level (longevity of 10 to 34 weeks with lower IFA titers). Since infection with one strain of O. tsutsugamushi does not preclude reinfection with other strains, understanding of the antigenic diversity of O. tsutsugamushi and duration of the immunity to both homologous and heterologous strain is very important in diagnosis of scrub typhus.

5.Expansile dentigerous cyst invading the entire maxillary sinus: a case report.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2012;38(4):245-248
Reported cases of a large dentigerous cyst involving the whole maxillary sinus are uncommon. A 22-year-old female patient suffering from swelling of the right infraorbital area and cheek with dull pain was referred to our department. Findings on computed tomography (CT) and magnetic resonance imaging (MRI) revealed a huge mass containing a displaced maxillary third molar involving the right maxillary sinus as a whole, with partial erosion of the posterior sinus cortical bone. Under general anesthesia, the mass was enucleated using the Caldwell-Luc approach, and, following histopathological analysis, was diagnosed as a dentigerous cyst. The case was followed for a period of seven years, and no evidence of sinus infection or recurring cyst formation was observed during that time.

PURPOSE: Because of recent global and domestic issues regarding the safety of food, there is growing concern over food safety and interest in the country-of-origin for food ingredients from restaurants. This study was conducted to reveal the influence of consumer level of knowledge and awareness regarding restaurants and the country-of-origin labeling. METHODS: To accomplish this, a primary survey of adults aged over 20 years old was conducted to measure customers' knowledge regarding country-of-origin labeling for restaurants. Respondents were then divided into a lower group and an upper group based on their level of knowledge to evaluate significant differences between groups. A total of 437 of 460 questionnaires were analyzed. RESULTS: The average knowledge score regarding country-of-origin labeling for restaurants was 6.3 out of 10. Additionally, there were significant differences between the lower and upper group in terms of the final education level and occupation. CONCLUSION: It is necessary to develop guidelines and public relations for country-of-origin labeling of restaurants.

Purpose:
Evidence on factors influencing the variations of music’s effect on anxiety and pain in surgical patients is unclear. We aimed to elucidate the effects of music intervention on anxiety and pain throughstudy characteristics.
Methods:
We conducted a search on the PubMed, CINAHL, Embase, Cochrane, and Web of Science databases from March 7 to April 21, 2022, for randomized controlled trials (RCTs) for the effect of music intervention on anxiety, pain, and physiological responses in surgical patients. We included studies published within the last 10 years. We assessed the risk of bias in the study using the Cochrane risk of bias tool for randomized trials and performed meta-analyses using a random-effects model for all outcomes. We used change-from-baseline scores as summary statistics and computed bias-corrected standardized mean differences (Hedges'g) for anxiety and pain outcomes and mean differences (MD) for blood pressure and heart rate.
Results:
Of the 454 records retrieved, 30 RCTs involving 2280 participants were found to be eligible. Music intervention was found to be superior to standard care in reducing anxiety (Hedges' g = −1.48, 95% confidence interval: −1.97 to −0.98), pain (Hedges's g = −0.67, −1.11 to −0.23), systolic blood pressure (MD = −4.62, −7.38 to −1.86), and heart rate (MD = −3.37, −6.65 to −0.10) in surgical patients. The impact of music on anxiety and pain relief varied significantly depending on the duration of the intervention. The largest effect was observed in interventions lasting between 30 and 60 minutes, with a decrease in anxiety and pain.
Conclusions
Music intervention is an effective way to reduce anxiety, pain, and physiological responses in surgical patients. Future reviews examining the influence of different types of surgery on the effects of music would add to the body of knowledge in this field. This study has been registered on the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42022340203, with a registration date of July 4, 2022.

PURPOSE: The purpose of this study was to identify the attitude of nurses toward transsexuals. METHOD: The Q-methodology which provides a method of analyzing the subjectivity of each item was used. Twenty-nine nurses classified the 50 selected Q-statements into a normal distribution using a 9 point scale. The collected data was analyzed using the Quanl PC program. RESULT: Four types of attitudes toward transsexuals were identified. The first type (humanitarian acceptance) showed an attitude of respecting transsexuals as human beings and understanding and accepting their desires and difficulties. The second type (superficial understanding) understood the psychological conflicts and suffering of transsexuals but could not accept them as members of families or society. The third type (insufficient understanding) did not feel a sense of rejection toward transsexuals but showed a lack of understanding of their desires and difficulties. The fourth type (rejection) failed to understand the desires and difficulties of transsexuals and showed a sense of rejection toward them, in addition to regarding them as sexually immoral people. CONCLUSION: The results of the study indicate that different approaches of educational programs based on the four types of attitudes toward transsexuals are recommended.

Objective:
We conducted this study to address the incidence and prevalence of schizophrenia and similar psychosis in South Korea with Health Insurance Review and Assessment (HIRA) database.
Methods:
We used HIRA database, which includes diagnostic information of nearly all Korean nationals to collect number of cases with diagnosis of schizophrenia and schizophrenia-similar disorders (SSP), including schizophreniform, acute/transient psychotic disorders, schizoaffective disorders, and other/unspecific nonorganic psychosis (ICD-10 codes F20/23/25/28/29) between 2010 and 2015. The annual prevalence and incidence were calculated using the population data from the Korean Statistical Office.
Results:
The 12-month prevalence of SSP of Korea between 2010 and 2015 were 0.48–0.66%. The 12-month prevalence of schizophrenia were 0.40–0.52%; The annual incidence rates (IR) of SSP between 2010 and 2015 were 118.8–148.7 per 100,000 person-year (PY). For schizophrenia, IR per 100,000 PY were 77.6–88.5 between 2010 and 2015.
Conclusion
The 12-month prevalence found in the present study was higher than that reported in community-based epidemiologic studies in South Korea but similar to those from other countries. The annual incidence of SSP and schizophrenia was found to steadily increase and was higher than that of other countries. The high incidence rate observed in the current study needs to be studied further.
