Objectives: Among the many intervention programs for children with autism spectrum disorder (ASD), the Early Start Denver Model (ESDM) is one of the few approaches that has succeeded in demonstrating clinical efficacy in randomized control trials. Here, we investigate the clinical efficacy of ESDM intervention in young children with ASD in a community setting within Japan. Methods: All subjects were children with ASD who received ESDM intervention during the study period. Each ESDM session lasted 75 min and occurred once per week for at least 12 weeks. The outcome measures consisted of the Kyoto Scale of Psychological Development (K-test), Aberrant Behavior Checklist-Japanese version (ABC-J), and the Clinical Global Impression-Severity scale (CGI-S). Results: Twenty-seven subjects (29.4±6.4 months old) received ESDM intervention that lasted for 8.0±2.6 months on average. The score on Language and Social developmental quotient on the K-test increased significantly after the intervention. The total scores on the ABC-J and CGI-S significantly decreased after completion of the ESDM intervention. Conclusion: Our results suggest that ESDM intervention could reduce the severity of distinct clinical features of ASD, such as impairments in social interaction and communication assessed by the K-test, and maladaptive behavior rated by the ABC-J and CGI-S. We believe that the ESDM adapted to each institution might become one of the standard options for children with ASD in Japan.

Background/Aims: Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewer migrations are required. This study aimed to assess the clinical performance of a novel, fully covered SEMS for unresectable MDBO. Methods: This was a multicenter single-arm prospective study. The primary outcome was a non-obstruction rate at 6 months. The secondary outcomes were overall survival (OS), recurrent biliary obstruction (RBO), time to RBO (TRBO), technical and clinical success, and adverse events. Results: A total of 73 patients were enrolled in this study. The non-obstruction rate at 6 months was 61%. The median OS and TRBO were 233 and 216 days, respectively. The technical and clinical success rates were 100% and 97%, respectively. Furthermore, the rate of occurrence of RBO and adverse events was 49% and 21%, respectively. The length of bile duct stenosis (<2.2 cm) was the only significant risk factor for stent migration. Conclusions: The non-obstruction rate of a novel fully covered SEMS for MDBO is comparable to that reported earlier but shorter than expected. Short bile duct stenosis is a significant risk factor for stent migration.

Invasive pulmonary aspergillosis (IPA) is rarely reported in patients who have normal immune function. Recently, IPA risk was reported in nonimmunocompromised hosts, such as patients with chronic obstructive pulmonary disease and critically ill patients in intensive care units. Moreover, influenza infection is also believed to be associated with IPA among immunocompetent patients. However, most reports on IPA with influenza A infection, including pandemic influenza H1N1, and IPA associated with influenza B infection were scarcely reported. Here, we report probable IPA with a fatal clinical course in an immunocompetent patient with influenza B infection. We demonstrate IPA as a possible complication in immunocompetent patients with influenza B infection. Early clinical suspicion of IPA and timely antifungal therapy are required for better outcomes in such cases.

Background: Limited data on the incidence and clinical characteristics of adult pertussis infections are available in Korea. Methods: Thirty-one hospitals and the Korean Centers for Disease Control and Prevention collaborated to investigate the incidence and clinical characteristics of pertussis infections among adults with a bothersome cough in non-outbreak, ordinary outpatient settings. Nasopharyngeal aspirates or nasopharyngeal swabs were collected for polymerase chain reaction (PCR) and culture tests. Results: The study enrolled 934 patients between September 2009 and April 2011. Five patients were diagnosed as confirmed cases, satisfying both clinical and laboratory criteria (five positive PCR and one concurrent positive culture). Among 607 patients with cough duration of at least 2 weeks, 504 satisfied the clinical criteria of the US Centers for Disease Control and Prevention (i.e., probable case). The clinical pertussis cases (i.e., both probable and confirmed cases) had a wide age distribution ($45.7{\pm}15.5$ years) and cough duration (median, 30 days; interquartile range, 18.0~50.0 days). In addition, sputum, rhinorrhea, and myalgia were less common and dyspnea was more common in the clinical cases, compared to the others (p=0.037, p=0.006, p=0.005, and p=0.030, respectively). Conclusion: The positive rate of pertussis infection may be low in non-outbreak, ordinary clinical settings if a PCR-based method is used. However, further prospective, well-designed, multicenter studies are needed.

The purpose of this study were to examine clinical dietetic performance level and to determine factors affecting clinical dietetic performance level. The survery was carried out for the 33 general hospitals over 400 beds in Seoul We established 13 factors which amy affect clinical dietetic performance level and investigated the relationship between these factors and clinical dietetic performance level. The average score of performance and perception of importance levels of clinical dietetic practices were 46.0${\pm}$6.9 and 73.2${\pm}$4.8 respectively. None of the demographic variables were significantly correlated to clinical dietetic performance level. Clinical dietetic performance level depended upon whether dietetic department had a division or not for clinical dietetic activities.

Carcinogenesis can be theoretically divided to intiation step and promotion step. Intiation associates with genetic alterations including p53 tumor suppressor gene and ras oncogene. Promotion involves in clonal expansion of of an initiated cell by epigenetic mechanism, mainly through signal transduction and gene expression. Ultraviolet light (UV) acts as both initiator and promoter. Initiation is closely related with DNA damage induced by UV, including cyclobutane pyrimidine dimers, (6-4) photoproducts and 8-hydroxy-2'-deoxyguanosine. Cyclobutane pyrimidine dimers and (6-4) photoproducts are directly induced by UV, while 8-hydroxy-2'-deoxyguanosine is induced indirectly by the reactive oxygen species. Because initiation is an irreversal genetic event, while promotion is a reversal and epigenetic event, to know the molecular mechanisms of tumor promotion in UV-carcinogenesis is crucial to develop preventive medicine and suppress UV-carcinogenesis. Because ROS is also involved in signal transduction of the cell, anti-oxidant could be the good candidate of anti-promoting agent. Here, we describe the suppressive effect of UV-carcinogenesis by various anti-oxidant including olive oil. In addition, we discuss about the mechanism of UVB-induced expression of cyclooxygenase-2, which might be a representative molecule involved in promotion of UV-carcinogenesis.

Paragonimiasis typically results from the consumption of raw or improperly cooked crustacea, especially crabs and crayfish. Although previously endemic in Korea, the prevalence of this disease decreased in the early 1970s because of educational campaigns and fewer intermediate hosts as a result of ecological changes. Recently, we were presented with a family where all members were infected with Paragonimus after ingestion of Kejang (= drunken crab). The mother was hospitalized for general myalgia and weakness first, followed by the father, who was hospitalized for dyspnea 2 month later. After the parents were diagnosed with paragonimiasis, we recommended their daughter to visit our hospital for a checkup, because they all had eaten freshwater crabs soaked in soybean sauce. She complained of generalized myalgia, fever, and pleuritic pain, and was also diagnosed with paragonimiasis. Peripheral blood of the 3 patients revealed hypereosinophilia, and computed tomography (CT) scans of their chests showed pleural effusion. The results of antibody tests by ELISA were positive for paragonimiasis. We report here the case series of familial paragonimiasis in a modern urban city, rather than in a typical endemic area.

Objectives: This study evaluated clinical trials of acupuncture treatment for hypertension and to assess their methodology and results. Methods: Eight Korean databases and four international databases were searched for clinical trials of acupuncture treatment for hypertension up to June 2011. Study quality was assessed using the risk of bias (ROB) tool. Results: Twenty-four trials of acupuncture for hypertension were included. There were 14 randomized and 1 non-randomized controlled trials and 9 before-after studies. The most frequently used acupuncture points were zsnli (ST36), qch (LI11), fngch (GB20), snynjio (SP06), snjin (LI03) and hgu (LI04). In more than half of the studies, needle retention time was 20~30 minutes. Compared to baseline, change of blood pressure after treatment was significant in all studies. However, the results of effect on blood pressure between acupuncture and control were not consistent. Conclusions: There is insufficient evidence to suggest that acupuncture is an effective treatment for hypertension. Further well-designed clinical trials will be required to evaluate the effects and safety of acupuncture treatment for hypertension.

Objectives: The purpose of this study was to investigate the effects of 56 herbal formulae covered by the National Health Insurance Corporation (NHIC) on dementia-related biomarkers and neuronal cell changes. Methods: The 56 herbal formulae were extracted with 70% ethanol at $100^{\circ}C$ for 2 h. The antioxidant properties was measured by radical scavenging assay using ABTS+ radical. The acetylcholinesterase (AChE) activity was tested by Ellman's assay and $amyloid-{\beta}$ ($A{\beta}$) aggregation was determined using fluorescence method. To estimate the inhibitory effects of herbal formulae on neuronal cell death and inflammation using HT22 hippocampal cells and BV-2 microglia, respectively. Results: Among the 56 herbal formulae, Dangguiyukhwangtang, Banhasasimtang, Samhwangsasimtang, Cheongwiesan, Hwangryunhaedoktang, Banhabaekchulchunmatang, Jaeumganghwatang, Cheongseoikgitang, and Hoechunyanggyuksan has a significant inhibitory effects on acetylcholinesterase (AChE) activity. Doinseunggitang and Samhwangsasimtang exerted the effect on the inhibition of $amyloid-{\beta}$ ($A{\beta}$) aggregation. Additionally, 10 herbal formulae affected AChE and $A{\beta}$ aggregation revealed antioxidant activity as well as neuroprotective and anti-neuroinflammation effects in neuronal cell lines. Conclusions: 10 herbal formulae that have been shown to be effective against the major dementia markers have been shown to have antioxidant activity, neuronal cell protection and inhibition of brain inflammation. Further investigation of these herbal formulae will need to be validated in dementia animal models.
