BACKGROUND: The pathological significance of adolescent obesity is increasing, as research results indicate that about 80 percent of obese teenager becomes obese as adults. However, most studies on obesity have been mainly centered on the biomolecular aspect of obesity, thereby offering little solution to the clinical application and the promotion of overall health for people. This study investigates into the psychological factors of adolescent obesity, mainly that relating to stress. METHODS: After having chosen 14 third year classes from two middle schools, one from the Kang nam and the other from the Kang puk region of Seoul, I have distributed questionnaires to the total of 501 students. For calculating the degree of stress among the students, I have employed the BEPSI (Brief Encounter Psychosocial Instrument) K, transforming each 5 positive questions into 1 point, which were summed up and divided by 5 (the BEPSI K score). RESULTS: Controlling the confounding factor, the regression coefficient regarding the Body Mass Index of the BEPSI K score was 0.661, t as 3.122, and R Square as 0.05, indicating the statistical relevance of the two factors. A multiple linear regression analysis of theses data yielded the following equation: Body Mass Index=15.6+0.661 x BEPSI K score(R2=0.05) Although the R Squre, as 0.05, was relatively low, this statistical result proves that the rise in stress contributes to the increase of Body Mass Index, thereby indicating that stress functions as an important factor for adolescent obesity. CONCLUSION: For remedying and preventing adolescent obesity, one must make use of the BEPSI K examination and calculate the degree of stress among the adolescent. This study further implies that the best solution to the problems of obesity among adolescent is for the family members, the educational institutions, and the society as a whole to understand and to help the adolescent overcome frequent mental stress resulting from their daily living.

Cartilage is commonly used autogenous material for aesthetic and reconstructive surgery and major donor sites of cartilage are ear, nasal septum, and rib. As the cartilage correlates with ossification and can be used for joint reconstruction. Many growth factors influencing growth and differentiation of chondrocytes have been reported, and matrix composition produced by chondrocytes may vary in types and quantity according to culture duration. Initially the chondrocytes in culture aggregate, then secrete type I collagen. Type II collagen is produced during differentiation process, and synthesis of type X collagen is the last step. In this study, chondrocytes were isolated from ear cartilage of the New Zealand white rabbit weighing 400 gm. We performed high density culture using penicylinder and pellet method. The cells were polygonal in morphology and viable under the inverted microscope. This experiment was designed to evaluate the effect of IGF-I, TGF- p, and b- FGF on the synthesis of collagen in chondrocyte culture. Optimal concentration of growth factors was determined using H-thymidine incorporation into DNA. After the addition of optimal concentration of each growth factors in experimental groups, the uptake of H-proline was measured. Only IGF-I showed a statistically significant increase of collagen synthesis. We observed how subtypes of collagen were influenced by growth factors in two culture methods and by differing the addition timing of growth factors. SDS-PAGE was adopted for subtyping of collagen. All subtypes of collagen were found in both culture methods and all growth factors facilitated the production of type II and type X collagen and may be devoted to the differentiation of chondrocytes. Immunohistochemical staining for type I, and type II collagen was examined to confirm the above result. In pellet culture, type II collagen was stained densely in response to the addition of three kinds of growth factors. The results of penicylinder culture showed similar outcome to those from pellet cultured group. From the above results, we concluded as follows; First, IGF-I generally influence the synthesis of type I and II collagen. Second, TGF beta increased the synthesis of collagen. Third, b-FGF increased the synthesis of type II and type X collagen. We concluded that IFG-I is the only growth factor which is effective regardless of culture duration and method. TGF- beta and b-FGF, which are potent mitogen, facilitate the secretion of collagen.

Purpose:
The purpose of this study is to find out the current status of toxicology laboratory operated by six locations nationwide and to investigate the satisfaction of emergency medical professionals who working at local and regional emergency medical centers.
Methods:
This survey was conducted prospective. It was conducted on 665 emergency medical professionals working at regional and regional emergency medical centers across the South Korea. Among them, the analysis was conducted with data that 510 emergency medical professionals who respond to this survey. The questionnaire was conducted on an online basis for a month. To ensure statistical significance, consider a dropout rate of 10% based on a minimum response recovery rate of 70%. 506 people were selected for the survey.
Results:
According to a survey on the status of addiction analysis room usage, the average monthly usage of addiction test rooms among respondents were 406 cases.71.0 cases (17.4%) of toxicology laboratory in Seoul and 71 cases (17.4%) in Gwangju. 32 cases (7.8%), 118 cases (29.0%) requested by toxicology laboratory in Busan, and the toxicology laboratory in Daegu. Eighty two cases (20.1%), Daejeon area 25 cases (6.1%), Wonju area toxicology laboratory was 78 (19.6%). According to a survey on the satisfaction of the addiction analysis room,Seoul (4.9±2.71) and Gwangju (4.8±2.52) showed high satisfaction.
Conclusion
Due to the limited operation time of the four addiction analysis rooms currently in operation, the satisfaction level of addiction analysis by emergency medical professionals in the area is low due to the delay until the result is notified.

OBJECTIVE: To evaluate the effect of aerobic exercise training on the cardiovascular system in the early stroke patients by bicycle ergometer exercise test. METHOD: 16 stroke patients without cardiac disease were randomly assigned to exercise training group (8 patients) and control group (8 patients). The time interval between the onset of stroke and exercise training was within 90 days. Exercise tests by bicycle ergometer using Astrand-Ryhming protocol were performed twice before and after training. Exercise training was consisted with the intensity of 60~70% of maximal heart rate, 30 minutes per day, 3 times per week for 6 weeks using bicycle ergometer. Modified Barthel Index (MBI) score and blood lipid profile were recorded before and during training. Blood pressure and heart rate were checked before and during exercise test. RESULTS: In a training group, maximal systolic blood pressure and rate pressure product were decreased immediately after exercise test after 6-weeks exercise training (p<0.05). The MBI score and lipid profile were not changed after training. CONCLUSION: Early exercise training in the stroke patients for 6 weeks have beneficial effects on the cardiovascular system.

Extended-spectrum beta-lactamase (ESBL) producing bacterial infection causes delayed response to antibiotic treatment and consequently results in serious problem, because it can hydrolyze the majority of beta-lactam antibiotics. Here we report a case of multiple renal abscess by ESBL producing Escherichia coli in a patient with diabetes mellitus who had a history of repetitive urinary tract infection. A 49-year old woman was admitted to our hospital because of intermittent fever, left flank pain, and vomiting. She had been diagnosed as acute pyelonephritis and treated with the first and third cephalosporin for 1 month at a clinic. At admission, urinary bacterial culture revealed Escherichia coli resistant to both the first and third cephalosporin such as cefotaxime, ceftriaxone, and ceftazidime. Double disk synergy test confirmed ESBL. Abdominal computed tomography demonstrated multiple renal abscess. After treatment of imipenam for 4 weeks, she discharged with improved condition.

PURPOSE: To determine the viability of human chondrocytes within refrigerated articular cartilage stored under conditions currently used clinically. MATERIALS AND METHODS: Osteochondral sections of human ankle taluses were stored at 4 degrees C in DMEM media for 1 to 42 days. Articular cartilage was harvested and evaluated for histologic changes and proteoglycan synthesis. RESULTS: By day 7, markedly decreased proteoglycan synthesis was observed. After 21 days, synthetic activity was virtually undetectable. Histologic specimens demonstrated chondrocyte death of a half of the cells from the superficial layer at day 7. Within 21 days, significant chondrocyte death was seen. CONCLUSION: These results suggest that proteoglycan synthetic activity and chondrocyte viability are markedly decreased in articular cartilage after cold storage for longer than 7 days.

PURPOSE: The aim of this study is to analyze the clinical results of using the technique of rotator cuff repair without parting the biceps long head from the glenoid for large or massive tear of the rotator cuff. MATERIAL AND METHODS: Form January 2005 to January 2007, we performed the arthroscopic biceps repair with incorporating suture to the rotator cuff for 21 patients with large or massive rotator cuff tear. The mean follow up period was 23 months (range: 6-48months). The number of males and females was 9 and 13, respectively. The age distribution ranged from 47 to 73 years with a mean age of 60.3 years. We compared the preoperative score with the postoperative scores using the University of California Los Angeles (UCLA) score, the shoulder index of the American Shoulder and Elbow Surgeons (ASES) and a simple shoulder test (SST). RESULTS: The improvement in the VAS, ASES and the UCLA and SST scores was statistically significant at the final follow up (average follow-up 23 months) (p>0.05). Two of nine cases were found to have partial tear with continuity but seven cases were found to have complete tear according to the ultrasonography and MRI. CONCLUSION: The technique of rotator cuff repair without parting the biceps long head from the glenoid for large or massive tear of the rotator cuff is considered to be recommendable.

Kawasaki diseases occur frequently in children beyond the age of 4 years, but classic Kawasaki disease in newborns are rare and have not been reported in Korea yet. We report a case of classic Kawasaki disease in neonate who is 21 days old girl and has no response to gamma-globulin although early diagnosis and treatment. Her clinical features met typical Kawasaki disease, but unusually she had a non suppurative labia major erythema and severe edema instead of cervical lymphadenitis. She had persistent fever and progressive carditis with coronary dilatation in spite of 3 doses of gamma globulin. Her fever was subsided after 3 doses of intravenous methyl prednisolone. In the subacute stage her other symptoms subsided and appeared typical desquamation of fingers and toe. Finally she had mild mitral regurgitation and diffuse coronary dilatation when she was discharged. Since one year follow up, with continuous aspirin medication, now she is very healthy, and her coronary dilatation was normalized and not any more valvular regurgitation.

Teratoma originate from one or more germ cell layer and commonly arise from sacrococcygeal area in neonate. Teratoma arising from the oropharyngeal cavity is called "epignathus tumor" and is extremely rare in neonate. Clinical manifestation of epignathus tumor vary from asymptomatic to severe respiratory distress symptom. It is reported that most of the tumor are benign in nature. Large teratoma can be diagnosed by prenatal ultrasonography, but most cases were diagnosed with computed tomography or magnetic resonance image after birth. Prognosis is determined by the need for neonatal resuscitation for respiratory distress at the time of birth and the extent of tumor, involving large vessles, skull base or communication with the brain. We experienced a case of epignathus tumor in a neonate with severe respiratory distress immediately after birth, so that reported with review of the literature.

Herpes zoster in infancy is very rare but can be developed following intrauterine or postnatal exposure to varicella zoster virus. We report a case of herpes zoster in a 4-month-old male infant. He had no prior history of primary varicella or varicella vaccination. His mother had no history of varicella infection and no contact history with varicella during pregnancy. He had a history of exposure to his father with herpes zoster 3 months ago, and to his cousin with convalescent chickenpox 2 months ago. Multinucleated, giant cells were shown on a Tzanck smear. He was treated with acyclovir and first generation cephalosporin for herpes zoster with Staphylococcal skin infection, with complete resolution without sequelae.
