Development of a questionnaire for the assessment of quality of life in korean children with allergic rhinitis.

PURPOSE: Korean children have their own unique lifestyle based on their living environment and culture. This study aimed to develop a questionnaire to evaluate the quality of life in Korean children with allergic rhinitis. METHODS: After a preliminary survey, an initial questionnaire was developed. Questions were modified to be easily understood by young children aged 6 to 7 years. The modified questionnaire was tested on children aged 6 to 12 years old. Item scores, defined as the proportion of children whose answer score was 1 point or higher was multiplied by the average answer score of each question, were used to identify questions that have practical application to the quality of life in Korean children with allergic rhinitis. Differences in answer scores between children with allergic rhinitis and those who were healthy were assessed by a Wilcoxon rank-sum test. The relationship between nasal index scores and quality of life scores was determined by a Spearman rank order test. RESULTS: An initial questionnaire was composed of 21 items. We identified 19 questions with item scores above 0.5 in children with allergic rhinitis, many of which were related to nasal symptoms and 10 questions that were different between the allergic rhinitis group and the control group. The final questionnaire included the 10 questions that had both high item scores and a significant difference in the answer scores between the two groups. CONCLUSIONS: The developed questionnaire is essential and practical for assessing discomfort related to the symptoms felt by Korean children with allergic rhinitis.

Significant adverse reactions to long-acting gonadotropin-releasing hormone agonists for the treatment of central precocious puberty and early onset puberty.

PURPOSE: Long-acting gonadotropin-releasing hormone agonists (GnRHa) are commonly used to treat central precocious puberty (CPP) in Korea. Although rare, there have been reports on the characteristic of adverse reactions of GnRHa in CPP among the Korean population. This study was intended to report on our clinical experience regarding significant adverse reactions to long-acting GnRHa in CPP and early onset puberty and to evaluate the prevalence rate of serious side effects. METHODS: This retrospective study included children with CPP and early onset puberty, who were administered monthly with long-acting GnRHa (leuprolide acetate, triptorelin acetate) at the outpatient clinic of Department of Pediatrics, at Inha University Hospital, between January 2011 and December 2013. We analyzed the clinical characteristics of patients who experienced significant adverse reactions and evaluated the prevalence rate. RESULTS: Six serious side effects (0.9%) were observed among total of 621 CPP and early onset puberty children with GnRHa therapy. The number of sterile abscess formation was four in three patients (4 events of 621). Anaphylaxis occurred in only one patient, and unilateral slipped capital femoral epiphysis (SCFE) in another one patient. Anaphylaxis occurred after the 6th administration of the monthly depot triptorelin acetate. Unilateral SCFE developed in GnRHa therapy. CONCLUSION: Sterile abscess formation occurred in 0.6% of CPP and early onset puberty patients from the administration of a monthly depot GnRHa therapy. The occurrences of anaphylaxis and SCFE are extremely rare, but can have serious implications on patients. Clinicians should be aware of these potential adverse effects related to GnRHa therapy in CPP.

Ubiquitous-severance hospital project: implementation and results.

OBJECTIVES: The purpose of this study was to review an implementation of u-Severance information system with focus on electronic hospital records (EHR) and to suggest future improvements. METHODS: Clinical Data Repository (CDR) of u-Severance involved implementing electronic medical records (EMR) as the basis of EHR and the management of individual health records. EHR were implemented with service enhancements extending to the clinical decision support system (CDSS) and expanding the knowledge base for research with a repository for clinical data and medical care information. RESULTS: The EMR system of Yonsei University Health Systems (YUHS) consists of HP integrity superdome servers using MS SQL as a database management system and MS Windows as its operating system. CONCLUSIONS: YUHS is a high-performing medical institution with regards to efficient management and customer satisfaction; however, after 5 years of implementation of u-Severance system, several limitations with regards to expandability and security have been identified.

Transfer of 90Sr to rice plants after its acute deposition onto flooded paddy soils.

The transfer of 90Sr to rice plants following its acute ground deposition was examined experimentally in a greenhouse. Lysimeters were flooded after being filled with the soil monoliths from 12 paddy fields. A solution of 90Sr was applied to the standing water in the flooded lysimeters at the pre-transplanting stage or booting stage. Applied 90Sr was mixed with the topsoil only after the pre-transplanting application (PTA). The transfer was quantified with the areal transfer factor (TF(a), m2 kg(-1)-dry) defined as the ratio of the plant concentration to the initial ground deposition. In the PTA, the first-year TF(a) values in the 12 soils were in the range of 8.2 x 10(-3) -2.1 x 10(-2) and 1.7 x 10(-4) -3.6 x 10(-4) for the straws and hulled seeds, respectively. The TF(a) values from the booting-stage application (BSA) were higher than those from the PTA by a factor of up to four. The ratios of the seed TF(a) to the straw TF(a) were, on the whole, higher in the BSA. The 90Sr TF(a) in the PTA was negatively correlated with the soil pH and, to a lesser degree, the exchangeable Ca content. In the second year, the TF(a) in the PTA reduced to 53-90% of that in the first year. A more significant reduction, in general, occurred in a sandier soil. Based on the four consecutive years' transfer data, an overall half-time of the 90Sr TF(a) was estimated to be 2.2 years.
