Background: In this study, we compared the incidents of humidifier disinfectants and incidents of mild hepatitis in Japan to highlight the differences in government response in the health care field in terms of “chain of responsibility”. Methods: We examined whether the three mechanisms of action and the chain of responsibility hypothesis were applied to compare the cases of Korea and Japan. The incident of Japan occurred in 1987 in Misawa city, Aomori prefecture. In the 1990s, the safety of blood products increased dramatically. However, relief for infected victims was neglected. Green Cross did not notify the parties. In Korea, in the spring of 2011, a number of lung disease patients were accidentally admitted to a hospital in Seoul, and a female patient with respiratory failure symptoms expired. The Korea Centers for Disease Control and Prevention conducted animal tests and the Ministry of Health and Welfare issued an order for forced collection of humidifier disinfectants. Results: In the case of Japan, the Ministry of Health and Welfare had to take responsibility for follow-up measures such as the investigation of the cause, so it was tied to a “chain of responsibility”. However, in the case of Korea, the Ministry of Health and Welfare was free from the chain. Conclusion Through the comparison between the cases of Japan and Korea, we confirmed that whether or not a government organization chooses to conceal responsibility depends on its past behavior, which is whether it is free from the chain of responsibility or not. Therefore, it was reaffirmed that an organization (ministry or department) free from the chain of responsibility must exist within the government.

Trichomoniasis is a sexually transmitted disease by Trichomonas vaginalis infection that may be associated with preterm delivery and low birth weight in the newborn infants. T. vaginalis may be transmitted to neonates during passage through an infected birth canal and neonatal infection is usually self-limiting course, but rare cases of symptomatic neonatal infection such as vaginitis, urinary tract infection and respiratory infection have been reported. We experienced a case of symptomatic neonatal trichomoniasis which was confirmed by wet mount examination of vaginal discharge and urine specimens in premature baby with intrauterine growth retardation. The patient had complete resolution of symptoms such as vaginal discharge and pyuria after treatment with ornidazole (tiberalR). We report this case with a brief review of the related literatures.

Caesalpinia sappan (C. sappan) is a medicinal plant used for promoting blood circulation and removing stasis. During a screening procedure on medicinal plants, the ethylacetate extract of the lignum of C. sappan (CLE) showed inhibitory activity on arginase which has recently been reported as a novel therapeutic target for the treatment of cardiovascular diseases such as atherosclerosis. CLE inhibited arginase II activity prepared from kidney lysate in a dose-dependent manner. In HUVECs, inhibition of arginase activity by CLE reciprocally increased NOx production through enhancement of eNOS dimer stability without any significant changes in the protein levels of eNOS and arginase II expression. Furthermore, CLE-dependent arginase inhibition resulted in increase of NO generation and decrease of superoxide production on endothelium of isolated mice aorta. These results indicate that CLE augments NO production on endothelium through inhibition of arginase activity, and may imply their usefulness for the treatment of cardiovascular diseases associated with endothelial dysfunction.

PURPOSE: The authors conducted a multicenter study to evaluate the efficacy and safety of combination chemotherapy with Padexol(R) and cisplatin for treating patients with advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: From November 2003 to April 2005, 42 chemo-naive patients with advanced NSCLC were enrolled into this study from 4 hospitals. The treatment consisted of Padexol(R) 175 mg/m2 as a 3-hr infusion, and this was followed by cisplatin 75 mg/m2 administered as an intravenous infusion with standard premedication. The treatment was repeated every 3 weeks. RESULTS: Among the 42 patients (pts), 33 pts were evaluable for response. On the per protocol analysis, 1 patient (pt) (3.0%) achieved complete response (CR), 17 pts (51.5%) achieved partial response (PR), 6 pts (18.2%) achieved stable disease (SD), and 9 pts (27.3%) progressed; therefore, the overall response rate was 54.6% (95% CI: 37.6~71.5%). On the intention-to-treat analysis, 1 pt (2.4%) achieved CR, 18 pts (42.9%) achieved PR, 11 pts (26.2%) achieved SD, and 9 pts (21.4%) progressed; therefore, the overall response rate was 45.2% (95% CI: 30.2~60.3%). The response, as evaluated by the investigators, was independently reviewed by 2 external radiologists and it was as follows; 13 PR (43.3%), 14 SD (46.7%) and 3 progressive disease (10%). The median duration of response was 5.9 months. The median follow-up duration was 10.3 months (range: 1.3 to 22.1 months). The median time to progression was 5.8 months (95% CI: 4.7 to 7.4 months). The median survival time on the intention-to-treat analysis was 10.5 months (95% CI: 8.1 to 18.8 months). The most common grade 3 or 4 hematologic toxicities were neutropenia (26/180 cycles, 14.4%), anemia (7/180 cycles, 3.9%) and febrile neutropenia (2/180 cycles, 1.1%). The most frequent grade 3 or 4 non-hematologic toxicities were nausea (14/42 patients, 14.3%), anorexia (3/42 patients, 7.1%) and myalgia (3/42 patients, 7.1%). CONCLUSION: The authors observed that Padexol(R) was as good as the other paclitaxel (Taxol(R) or Genexol(R)) formulations when combined with cisplatin for treating patients with advanced NSCLC.

The objective of this study was to review the natural history of extrapulmonary small cell carcinoma (EPSCC) with specific emphasis on clinical features, response to treatment and survival. The records of all patients (n=34) with EPSCC treated at Yeungnam University Medical Center and Catholic University of Daegu Medical Center between 1998 and 2005 were retrieved and reviewed. The primary sites of tumor were the esophagus and thymus in 6 patients (17.6%) each, pancreas and stomach in 5 patients each (14.7%); other sites included were the cervix, abdominal lymph nodes, abdominal wall, bladder, colon, maxillary sinus, nasal cavity, ovary, parotid gland and liver. Twenty three patients out of 34 had limited disease. The median survival of all patients was 14 months. Independent prognostic factors included stage and primary tumor location. The prognosis for the patients with extensive disease and in the gastrointestinal group was unfavorable. EPSCC is a non homogeneous disease entity. As a result of its frequent recurrence, multimodal therapy has a better outcome even in cases of limited disease. Combination chemotherapy plays a central role for treatment of extensive disease in EPSCC. Further multicenter studies are now needed to determine more details regarding disease sub-class and optimal treatment modality.

PURPOSE: This study was conducted to confirm the efficacy and toxicity of docetaxel and cisplatin combination chemotherapy (DP) in patients with advanced gastric cancer. MATERIALS AND METHODS: Patients with measurable gastric adenocarcinoma received intravenous docetaxel 75 mg/m2 and cisplatin 75 mg/m2 with premedication on day 1, which was repeated every 3 weeks. All patients received DP as a second-line treatment after failing to 5-FU based chemotherapy. RESULTS: 34 patients were enrolled in this study between January 1998 and August 2003. A total of 112 cycles (median 3 cycles) were administered. Responses were evaluable in 30 patients. The objective response rate was 16.7% (95% CI: 3.5~30.3), with a stable disease in 56.7% (95% CI: 40.0~74.4) and a progressive disease in 26.7% (95% CI: 10.9~42.5) of patients, with a median follow up duration of 20 months for all the patients, The median duration of response, time to progression and overall survival were 2.1 months (95% CI: 0.4~3.9), 4.2 months (95% CI: 2.3~6.1) and 6.8 months (95% CI: 1.3~12.3), respectively, with a 1-year survival rate of 32%. The toxicity was evaluated in 30 patients, with neutropenia being most common. Renal impairment was seen in two patients with grade 3 creatinine elevation and liver enzyme elevation in four with grades 3 and 4. CONCLUSION: Although DP was an active combination regimen, with a tumor control rate of about 73% and with moderate tolerance, adjustment of the administration schedule, with further evaluation of other combination chemotherapies of docetaxel with new agents, other than cisplatin, seem warranted.

PURPOSE: Croup is a common respiratory disease in children. The aim of this study was to analyze the epidemiology, etiology, and seasonal variations of respiratory virus infections in children with croup. METHODS: From October 2009 to September 2017, children admitted with croup to Gachon University Gil Medical Center under the age of 18 years were enrolled in this study. We retrospectively reviewed patients' medical records. RESULTS: A total of 1,053 of 27,330 patients (3.9%) infected with lower respiratory infections were diagnosed as having croup. In the age distribution, croup was most common (50.0%) in children aged 1 to <2 years. There were 2 peaks, the major in summer (July to August) and the minor in spring (March to May). Parainfluenza virus type 1 (15.8%) was most prevalent and coincided with the summer peaks of croup. Influenza virus type B and parainfluenza virus type 3 were the most frequent etiologic agents in a spring peak of croup. Although parainfluenza virus type 1 was predominant of all ages, human coronavirus was a significant cause of croup in children younger than 1 year, whereas influenza virus played an important role in children above the age of 3 years. CONCLUSION: Seasonality and epidemiology of croup varied with age and regions. Two peaks of seasonal fluctuation were in summer and spring, which were related to the seasonality of respiratory viruses in croup. These results may be helpful in planning clinical and research needs.

BACKGROUND: Non-Hodgkin's lymphoma presenting in the eye is a rare disorder. The aim of this study was to evaluate the clinical features, treatment outcome and complications of patients with non-Hodgkin's lymphoma of the eye. METHODS: We designed retrospective, observational case study. The participants included 22 consecutive patients with non-Hodgkin's lymphoma of the orbit and ocular adnexa treated at the Yeungnam University Hospital between 1992 and 2001. RESULTS: There were 16 males (73%) and 6 females (27%). The median age at ocular presentation was 47. The most common presenting complaint was slowly growing mass at the eye. Histopathologic studies revealed extranodal marginal zone B-cell lymphoma, MALT type in 19 cases (86%), B-cell small lymphocytic lymphoma in one case, diffuse large B-cell lymphoma in one case, and lymphoplasmacytoid lymphoma/immunocytoma in one case. The stages of lymphomas were IA(E) in 17 cases (82%), IIA(E) in 2 cases (9%), IIIA(E) in 2 cases (9%). Radiotherapy alone was employed in 17 cases, chemoradiotherapy was done in 3 cases, chemotherapy alone was administered in one case. Nineteen out of 21 cases (90%) achieved a complete remission, and 5 year survival rate was approximately 90%. Subgroup analysis of the patients with lymphomas in stage IA(E) revealed that complete response rate was 100% and 5 year survival rate was 100% CONCLUSION: Radiotherapy alone can produce durable remission in the majority of the patients with localized extranodal marginal zone B-cell lymphoma, MALT type. However, combination chemotherapy or chemoradiotherapy should be considered in the patients with aggressive lymphomas or indolent lymphomas with systemic manifestation.

Background: Only a few studies have tried to assess factors relevant to the satisfaction of the participants in atopic dermatitis (AD) educational programs. More systematic modeling of this issue is needed. Objective: To examine the benefit of a conjoint educational program for AD on patients and caregivers in a clinical setting. Methods: In a half-day educational program called “AD school”, 831 people (493 patients and 338 family members) participated for 8 years. Various educational and entertaining programs were provided. The on-site survey was administered to measure participants’ satisfaction and perception of the benefit. We applied structural equation modeling to identify the relations among satisfaction and perception. Results: A total of 209 family survey data was obtained and analyzed. The survey items were grouped into four categories. The categories were classified as individual education, group education, fun activity, and overall satisfaction (fun, benefit, intention to re-join and recommend to others). According to the model that we built, comprehensive group education was demonstrated to be the most relevant factor affecting overall satisfaction. Conclusion Our holistic approach would allow dermatologists to improve the efficacy of the conjoint educational program for AD.
