OBJECTIVE: To evaluate usefulness of uptake ratio of three phase bone scintigraphy in assessing the complex regional pain syndrome (CRPS) type I in stroke patients METHOD: Forty three stroke patients were diagnosed as CRPS type I based on their symptoms and confirmed by three phase bone scintigraphy. Uptake ratio was calculated by dividing the radioactivity count on the affected side by that on the unaffected side in each phase. Mean uptake ratio was compared among the groups classified by the clinical diagnosis and by the response to treatment. In addition, uptake ratio was compared before and after treatment. RESULTS: Mean uptake ratio of the wrist in blood pool phase was significantly higher than other parts of the body (p<0.05). However, there was no significant difference among the groups classified by the clinical diagnosis nor by the response to treatment. The changes of uptake ratio were variable after treatment, but only the uptake ratio of the wrist in blood flow phase showed correlation with the degree of swelling. CONCLUSION: Uptake ratio of three phase bone scintigraphy was not correlated with clinical findings.

BACKGROUND/OBJECTIVES: This study was conducted to examine disparities in food and nutrient intakes based on family types identified among 1,856 participants who were the Korean elderly people in the 6th Korea National Health and Nutrition Examination Survey (KNHNES) excluding those who were currently practicing the diet therapy. SUBJECTS/METHODS: We separated the subjects into two groups: living alone (LA, n = 638) and living with a spouse (LS, n = 1,218). We also examined the disparities of dietary quantity and quality of those two groups using complex sampling design general linear regression analyses (CS GLM). RESULTS: In the LA group, there was a higher percentage of females and average age in LA group was higher than the participants in the LS group. Household income and education level were significantly lower in LA compared to those of LS. The frequencies of skipping meals were higher in LA. LA's food and nutrient intakes showed lower consumption of vegetables, fruits, seaweeds, and of most nutrients. Even after adjusting for the confounding factors, the consumption of vegetables, seaweeds, carbohydrates, potassium, riboflavin, and vitamin C showed lower in LA than LS. Moreover, LA's nutrient intake ratios compared to the KDRIs were lower which turned out to be similar to their nutrient intakes. CONCLUSIONS These results show that dietary behavior and food intake of the elderly are associated with family types. Frequently skipping meals and less dietary variety are more common with elderly persons who were living alone. Therefore, it is necessary to integrate the supplementary food programs and nutrition education programs for the elderly living alone.

Background: Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease.Although murine studies have demonstrated that type 2 innate lymphoid cells (ILCs) mediate type 2 skin inflammation, their role in skin fibrosis in AD remains unclear. This study investigated whether type 2 ILCs are involved in skin fibrosis using an AD-like murine model. Methods: C57BL/6 mice were treated epicutaneously with Aspergillus fumigatus (Af) for 5 consecutive days per week for 5 weeks to induce skin fibrosis. Mature lymphocyte deficient Rag1−/− mice were also used to investigate the role of type 2 ILCs in skin fibrosis. Results: The clinical score and transepidermal water loss (TEWL) were significantly higher in the AD group than in the control group. The AD group also showed significantly increased epidermal and dermal thicknesses and significantly higher numbers of eosinophils, neutrophils, mast cells, and lymphocytes in the lesional skin than the control group. The lesional skin of the AD group showed increased stain of collagen and significantly higher levels of collagen than the control group (10.4 ± 2.2 µg/mg vs. 1.6 ± 0.1 µg/mg, P < 0.05). The AD group showed significantly higher populations of type 2 ILCs in the lesional skin compared to the control group (0.08 ± 0.01% vs. 0.03 ± 0.01%, P < 0.05). These findings were also similar with the AD group of Rag1−/− mice compared to their control group. Depletion of type 2 ILCs with anti-CD90.2 monoclonal antibodies significantly improved clinical symptom score, TEWL, and infiltration of inflammatory cells, and significantly decreased levels of collagen were observed in the AD group of Rag1−/− mice (1.6 ± 0.0 μg/mg vs. 4.5 ± 0.3 μg/mg, P < 0.001). Conclusion In the Af-induced AD-like murine model, type 2 ILCs were elevated, with increased levels of collagen. Additionally, removal of type 2 ILCs resulted in decreased collagen levels and improved AD-like pathological findings. These findings suggest that type 2 ILCs play a role in the mechanism of skin fibrosis in AD.

OBJECTIVE: To prospectively investigate the long-term effects of botulinum toxin treatment on the upper limb function and performance of school age children with spastic bilateral cerebral palsy, who have limitations in performing activities of daily living and school activities, due to spasticity of the upper extremities. METHODS: Botulinum type A toxin (BoNT-A) was injected into 24 spastic upper limbs of 15 children. We used a Modified Ashworth Scale and a Modified Tardieu Scale for the evaluation of upper limb spasticity, and Quality of Upper Extremity Skills Test (QUEST), Canadian Occupational Performance Measure (COPM), and Test of Visual-Motor Skills-Revised (TVMS-R) for the evaluation of upper limb function and performance. RESULTS: Upper limb spasticity continuously decreased until the end of the one-year follow-up. Upper limb function on QUEST and COPM showed the best performance at 3 months and deteriorated slightly, but still showed a significantly better performance at 9 and 12 months than at pre-injection. In more functional nine subjects who could perform TVMS-R, the performance enhancement effects remained constant after 12 months, suggesting that the reduced spasticity led to the learning effect acquired by the repeated use of the affected upper limb. CONCLUSION: For school age children with bilateral spastic cerebral palsy whose upper limb functions are important, BoNT-A injections seem to be of help in the performance of school activities and activities of daily living.

Recently, mini-implant is popular in the orthodontic treatment due to its simplicity and convenient surgical procedure. The objective of this study is to provide the anatomical guideline for mini-implant placement by analysing the cortical bone thickness in Korean. Hemi-sections of sixteen maxillae and twenty-two mandibles with normal teeth were used. Interdental areas between the 1st premolar and the 2nd premolar (Group 1), the 2nd premolar and the 1st molar (Gruop 2), and the 1st molar and the 2nd molar (Group 3) were sectioned and then scanned. After setting the axis of teeth, the cortical bone thickness was measured at the distance of 2 mm, 4mm, 6 mm, and 8 mm from alveolar crest. The mean thickness of cortical bone in the maxilla according to distance from alveolar crest was 1.30 +/- 0.63 mm (2 mm), 1.49 +/- 0.62 mm (4mm), 1.72 +/- 0.64 mm (6mm), and 1.90 +/- 0.90 mm (8 mm) at the buccal side and 1.33 +/- 0.47 mm, 1.31 +/- 0.45 mm, 1.37 +/- 0.55 mm, and 1.39 +/- 0.58 mm at the palatal side. In the mandible, that was 3.14 +/- 1.71 mm, 4.31 +/- 2.22 mm, 4.23 +/- 1.94 mm, and 4.30 +/- 1.57 mm at the buccal side and 1.98 +/- 0.88 mm, 2.79 +/- 1.01 mm, 3.35 +/- 1.27 mm, and 3.93 +/- 1.38 mm at the lingual side. The buccal cortical bone thickness in the maxilla was decreased from Group 1 to Group 3, while the thickness of palatal side was no change. In the mandible, it did not show a tendency at the buccal side and it was decreased from Group 1 to Group 3 without significant difference at the lingual side. Therefore, the buccal side of the Group 1 and Group 2 in both the maxilla and mandible seems to be the most appropriate site for a mini-implant placement with taking the stability and retention.

OBJECTIVE: To evaluate the level of depression, anxiety and quality of life in primary caregivers for the severe stroke patients. METHOD: We studied a sample of 44 severe stroke patients and their primary caregivers. Functional status of the severe stroke patients was evaluated by Modified Barthel Index (MBI). We collected the data through interviewing the caregivers and using the Beck Depression Inventory (BDI), State- Trait Anxiety Inventory (STAI), Ego-strength scale, Short Form Health Survey-36 (SF-36) and Family APGAR (Adaptation, Partnership, Growth, Affection and Resolve) score. RESULTS: The average level of depression in caregivers was low. The mean socres of STAI were 41.5 for state anxiety and 44.3 for trait anxiety, respectively. Ego-strength scale was significantly inversely related to BDI score and trait anxiety inventory score, but positively related to SF-36 score. The most influencing factor for the SF-36 score was the BDI score. CONCLUSION: Primary caregivers for the home-bound severe stroke patients demonstrated a lower level of quality of life, especially mental health, general health and vitality component. Community based rehabilitation should more focus on the evaluation and support for caregiver's psychologic status and their quality of life.

PURPOSE: Recently, the trend of multi-cultural families is rising in number due to increasing marriage-based immigrants in Korea. We evaluated statistic changes of characteristics in international marriage, births, and off-springs for the past 20 years in Korea. METHODS: The annual report of national population from Statistics Korea, the survey results about the present status of resident foreigners from Korea Ministry of Health and Welfare, Korea Ministry of Public Administration and Security, and editorials from Health and Welfare Forum and other related reports of Korea Institute for Health and Social Affairs and Korea Ministry of Health and Welfare were used. RESULTS: There were 35,098 (10.8%) international marriages among total 326,104 marriages in 2010 in Korea. The regional distribution of the international marriage was the highest in Gyeonggi (18.5%), and the lowest in Jeju (1.1%). The metropolitan area Seoul (15.4%), Incheon (4.5%) and Gyeonggi (18.3%) comprised one third of the entire international marriage. The number of childbirths was 13,443 (2.9%) in 2008, 19,024 (4.3%) in 2009, and 20,312 (4.3%) in 2010 with increasing trend. The number of off-springs was 44,258 in 2007, 58,007 in 2008, 99,684 in 2009 and 105,502 in 2010. Children less than 18 years old was 93.1%. We expected 1.5 times of increase over the next coming 10 years in the number of multi-cultural international marriage and off-springs compared with 2011. CONCLUSION: When we evaluated the characteristics of multi-cultural marriages, childbirths, and off-springs, systemic nationwide care seemed to be necessary in the aspect of health problems such as perinatology, obstetrics, neonatology, and pediatrics. We expect our results to be utilized for the basic health data.

Levofloxacin is a broad-spectrum antibiotic with activity against gram-positive and -negative bacteria. This study compared the pharmacokinetics (PK) and evaluated the bioequivalence of two levofloxacin 100-mg tablet formulations. An open, randomized, two-way crossover study was conducted in 28 healthy volunteers. The reference (Cravit Tab 100-mg, Jeil) or test (Levobacter Tab, Seoul) formulation was administered and serial blood samples were collected over 24 h for PK analysis. Levofloxacin plasma concentrations were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The correlation of levofloxacin concentration at various time points with the area under the concentration time-curve over the time interval from 0 extrapolated to infinity (AUCinf) was estimated to determine the best reflected time point. The average half-life, maximum plasma concentration (Cmax), and AUClast were comparable. The 90% confidence intervals (CIs) of the geometric mean ratio (GMR test/reference) of AUClast and Cmax were 0.8200-1.0633 and 0.9474-1.0643 respectively. Both formulations were tolerated with no clinically relevant safety issues. Plasma levofloxacin concentrations at various time points correlated well with the AUCinf, and showed high correlation coefficients (r > 0.7, P < 0.001) for both drugs 8 and 12 h after administration. Both formulations showed similar PK profiles while levofloxacin plasma levels after administration indicated their bioequivalence. The Cmax and AUClast GMR 90% CIs were 0.80-1.25. Moreover, 12 h was the best time point to predict the AUCinf and therefore suitable for therapeutic drug monitoring.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about 'Table etiquette', 'Reasons for eating fruits and vegetables'(78.7%), 'Food waste and environment'(72.3%), 'Healthy snacks'(55.7%), 'Food sanitation'(52.3%), 'Food culture of foreign countries'(48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about 'basic food preperation'(p < 0.01). They had learned 'Nutrients for body'and 'Food waste and environment'in school, 'Healthy weight loss', 'Food culture of foreign countries', 'Food circulation'on television, Most content ('Table etiquette', 'Simple cooking', 'Food sanitation', 'Eating behaviors for health', 'Reasons for eating fruits and vegetables', 'Healthy snacks') was learned from parents. The practice after nutrition education was higher in 'Table etiquette'(2.14), 'Eating fruits and vegetables'(2.07) than others compared with education experience. The most reason of non-practice on nutrition information was 'Troublesome'. In 'Nutrients for body', a boy answered 'Difficult for practice'20.0%, a girl answered 'Difficult to understand'32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the 'Nutrients for body'(49.6%), 'Food sanitation'(44.5%) because of 'important content', 'Basic food preparation'(40.6%), 'Food culture of foreign countries'(36.3%) because of 'interesting content', 'Healthy weight loss'(52.0%), 'Eating behavior for health'(44.5%) and 'Healthy snacks'(33.7%) because of 'need for my health'.
