Awareness and Intake of Caffeine-Containing Foods among High School Students in Seoul

The high caffeine intake by adolescents has been a concern. The purpose of this study was to examine the awareness and consumption of caffeine-containing foods among 443 high school students using a questionnaire. An analysis of the spending patterns of the students’ weekly allowance showed that the amounts spent on purchasing caffeine-containing foods were higher for female students than male students (P ＜0.001). The scoring of the perception of caffeine was 3.1 out of 5, interest in the caffeine content of food was 2.6, consumption of caffeine-containing foods was 2.6, and usefulness of caffeine-containing foods was 2.7. The awareness of caffeine content in food was significantly higher in females (7.3 out of 11) than male students (6.7) (P＜0.01). Approximately 59% of students perceived that the relationship between caffeine-containing foods and health, was harmful, and the experience of side effects after taking caffeine was significantly higher in female students than males. These side effects include heartburn (P＜0.001), headache or dizziness (P＜0.001), irregular heartbeat (P＜0.05), and hands and feet shake (P＜0.01). Caffeine-containing foods were purchased at convenience stores (62.1%). The factor considered when purchasing caffeine-containing foods was taste (72.2%), and the use of nutrition labeling for caffeine-containing foods scored 2.0 out of 5 points. When assessing the intake of caffeine-containing foods, the foods consumed more than once a week were in the order of coke, chocolate, chocolate milk, chocolate pie, and chocolate bars. These results suggest that it is necessary to prepare a caffeine-related nutrition guide improvement by sales management, and strengthen food labeling standards for the desirable recognition of caffeine and its safe intake by adolescents.

Knowledge of human papillomavirus infection and acceptability of vaccination among adult women in Korea / 대한산부인과학회지

OBJECTIVE: The HPV vaccination target adolescents, and may be influenced by opinion of parents and other family member. For implementation of HPV vaccine, we measured knowledge of HPV infection and acceptability of vaccination among adults in Korea. METHODS: From August 2006 to November 2007, we provided a written questionnaire to females (above 19 years- olds) who visited Il-sin Christian hospital for prenatal care or gynecological examination. The questionnaire was built using elements of The Health Belief Model. We measured (1) awareness of HPV (2) perceived susceptibility (3) perceived seriousness (4) perceived benefit of vaccination (5) perceived barriers (6) cues to action. RESULTS: Total 975 females answered the questionnaire, and the mean age was 40 years. Only 23.8% knew the fact cervical cancer is related to HPV infection. 78.3% of respondents were willing to accept HPV vaccination after they understood HPV vaccination can prevent cervical cancer. Financial burden and possible side effect were barriers to vaccination. CONCLUSIONS: Despite of low awareness of HPV infection, most (78.3%) adults favored having HPV vaccination. But the vaccine was more likely to be accepted if it is recommended by a physician and reasonably priced.

Dynamic left ventricular outflow tract obstruction without basal septal hypertrophy, caused by catecholamine therapy and volume depletion

Hypertrophic cardiomyopathy (HCM) with hypertrophy of the basal septum is the most common etiology of left ventricular outflow tract (LVOT) obstruction. In this article, we report the case of a patient with a structurally normal heart who developed hemodynamic deterioration due to severe LVOT obstruction following treatment with catecholamines. Hypovolemia accompanied with a hyperdynamic condition, resulting from catecholamine treatment, may cause dynamic LVOT obstruction due to the systolic anterior motion of the mitral valve leaflet. The solution for this is early recognition and correction of aggravating factors such as, withdrawal of catecholamine therapy and volume replacement.

A Case of Gastric Bezoar Treated by an Endoscopic Coca-Cola Injection / 대한소화기내시경학회지

Bezoars are the most common foreign bodies in the stomach as seen endoscopically with a frequency of approximately 0.4%. They consist of persistent concretions or hard accumulations of non-digestible vegetable matter, hair or more unusual materials. Gastric bezoars develop in patients with previous gastric surgery, gastric outlet obstruction, or poor gastric emptying such as gastroparesis due to hypothyroidism, diabetes mellitus or mixed connective tissue disease. The clinical presentations of gastric bezoars include epigastric pain, a palpable mass, a gastrointestinal obstruction and peptic ulceration. The treatment options include surgery, enzymatic dissolution or endoscopic mechanical fragmentation and/or removal. Recently, the efficacy of the administration or lavage of 'Coca-Cola' for the effective dissolution of gastric bezoars has been reported. We report a case of a 27-year-old woman with a large gastric bezoar that was successfully removed by the direct endoscopic injection of a carbonated beverage ('Coca-Cola light', a sugar free product; Coca cola Co., Seoul, South Korea) into the bezoar, which led to fragmentatio

Multicystic Pulmonary Parenchymal Lesions in a Young Adult with Hemoptysis / 결핵및호흡기질환

Bronchogenic cysts are commonly located in the mediastinum or lung parenchyma, and arise from the abnormal budding of the primitive tracheobronchial tube. Cough and pain are the most common symptoms. Bronchogenic cysts appear as spherical or oval masses with smooth outlines and are usually unilocular and noncalcified. We report a young adult with a bronchogenic cyst presenting as multicystic pulmonary parenchymal lesions. This case is very unusual because a multicystic intrapulmonary bronchogenic cyst is very rare in adults.

A Case of Sirenomelia without Oligohydramnios Diagnosed in Early Second Trimester / 대한주산의학회잡지

Sirenomelia is rare congenital malformation characterized by fusion of the lower extrimities associated anomalies included absence of urogenital system (bilateral renal agenesis, absent ureter, urinary bladder, absent internal and external genitalia), induced severe oligohydramnios, anorectal atresia, single umbilical artery, pulmonary hypoplasia. The incidence is 1:60000 births. Survival is extremely rare, and only possible, in the absence of bilateral renal agenesis. In view of the dismal prognosis, early diagnosis allows for earlier and less traumatic therapeutic abortion. We report a case of sirenomelia without oligohydramnios diagnosed in early second trimester.

ThE Role of Endoscopic Surgery for Completely Obstructive Endobronchial Benign Tumor

BACKGROUND: The improving techniques of therapeutic bronchoscopy have been replacing conventional surgery for resecting endobronchial benign tumor. However, there could be some limitation for performing bronchoscopic intervention for the patients with complete bronchial obstruction. To evaluate the role of endoscopic surgery for completely obstructive endobronchial benign tumor, we retrospectively reviewed the medical records of 7 patients who underwent bronchoscopic resection due to completely obstructive benign tumor. METHODS: Rigid bronchoscopy was performed under general anesthesia. After the stalk of tumor was identified with using a 1 mm biopsy forceps as a probe, a Nd-YAG laser was used to coagulate the stalk of tumor. The tumor was then removed. RESULTS: Bronchoscopic resection was successful in 6 out of 7 patients. The histological diagnoses were 3 leiomyomas, 3 harmatomas and 1 lipoma. There was no mortality in our study. Pneumomediastinum developed in 1 patient, and this patient was treated with 3 days of oxygen therapy. In 5 out of the 6 successful patients, there was no recurrence for a median of 35 months. In 1 patient, leiomyoma recurred after 17 months, and this was treated by pneumonectomy. CONCLUSIONS: Endoscopic surgery could be applied to the patients with completely obstructive endobronchial benign tumor.

A Comparative Study on the Serum Lipid Levels and the Dietary Intake of Physical Education Major and Non-Major Male Students / 대한지역사회영양학회지

The paper examines the effect of physical exercise on blood lipid with young male students. Our analysis is based on the body measurement, food intake and blood lipid component for 70 male students of Kongju National University who either major in physical exercise (group A) or do not major in physical exercise (group B). The average weight of group A is 71.97 +/- 10.79 kg while that of group B is 67.57 +/- 8.66 kg. The former is significantly higher (p < 0.05) than the latter. The SBP of group A (128.20 +/- 11.40 mmHg) is significantly (p < 0.001) higher than that of group B (136.27 +/- 13.18 mmHg). In terms of the intake of total kcal, group A marks significantly higher than group B; group A goes with 2190.26 +/- 581.96 kcal and group B goes with 2392.94 +/- 769.03 kcal. The comparative analysis of the three nutrient intake shows that the intake proportions for group A are carbohydrate 55.08 +/- 6.03%, protein 15.58 +/- 2.75%, and lipid 29.34 +/- 5.16% while the intake proportions for group B are carbohydrate 57.29 +/- 8.09%, protein 15.62 +/- 3.26%, and lipid 27.10 +/- 6.90%. For group A, the vitamin B1 intake amounts to 1.50 +/- 0.5 mg which fulfills 100% of RDA, and the niacin intake amounts to 16.57 +/- 5.54 mgN.E which is less than RDA. In contrast, both intakes for group B are more than the RDA. In the case with minerals except calcium, both group A and B mark more intake than RDA. Group A's calcium intake is 517.12 +/- 200.63 mg and group B's is 409.56 mg. The total cholesterol intake for group A is 447.00 +/- 245.08 mg which is significantly (p < 0.05) higher than for group B with 352.35 +/- 200.25 mg. The total cholesterol in the lipid of serum is 151.30 +/- 12.92 mg/dl for group A and 182.30 mg/dl for group B, where the dominance of group B over group A is true at the level of significance 0.01. In the case with triglyceride, group A is 107.57 +/- 31.60 mg/dl and group B is 108.07 +/- 33.93 mg/dl so that the group difference is non-significant. The HDLcholesterol for group A is 54.67 +/- 6.49 mg/dl which is significantly higher (p < 0.001) than for group B with 36.13 +/- 4.64 mg/dl. We conclude that regular exercise may have an effect on blood lipid metabolism among young males.
