BACKGROUND/OBJECTIVES: Eating out has been reported to have negative effects on nutritional status. However, eating out can include meals prepared at home and eaten outside. Conversely, meals eaten at home can be brought from outside, as take-out and home deliveries have become common in Korea. Thus, we tested whether or not meal preparation location influences daily diet quality. SUBJECTS/METHODS: From the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2009, 4,915 Korean adults (20-64 years) were classified into two groups: home-made meal group (HMG), who ate ≥ 2 meals per day prepared at home (n = 4,146), and non-home-made meal group (NHMG), who ate ≥ 2 meals per day prepared outside home (n = 769). Daily diet quality was determined by energy intake, nutrient intake, Dietary Variety Score (DVS), and Diet Diversity Score (DDS). RESULTS: Compared to the HMG, the NHMG was more likely to consist of men, single, employed, educated and of a higher economic status (all, P < 0.01). The NHMG showed higher energy intakes (1,776 vs. 2,116 kcal/day) with higher percentages of energy from protein (15 vs. 23%) and fat (14 vs. 16%) and lower intakes of dietary fiber, phosphorus, potassium, niacin, and vitamin C (all, P < 0.01) than the HMG, with some variations among age groups. The NHMG tended to consume foods prepared by frying and grilling and had more one-dish meals such as bibimbap, noodles, and dumplings but also showed higher dietary diversity. CONCLUSIONS: It should be noted that home-made meals do not necessarily guarantee a healthy diet, and the effects of meal preparation location on nutritional status might vary depending on socio-demographic characteristics.

Poor R-Wave Progression(PRWP) of precordial leads is frequently encountered electrocardiographic findings of uncertain significance and has simply been deemed as suggestion of anterior myocardial infarction without concrete ground. 217 cases with poor R-Wave Progression have been analyzed on clinical records and results are as follows. 1) PRWP was most frequently found in fifties and sixities, comprising 63.9% of the subjects. 2) Co-existent disease entities with PRWP were classified into three categories, cardiovascular diseases, chronic lung diseases and normal variants. 3) The cardiovascular diseases related with PRWP were mainly hypertensive diseases, comprising 59.8% of cardiovascular diseases, followed by ischemic heart disease, valvular heart disease and cardiomyopathies. 4) PRWP may be an early sign of acute myocardial infarction in a certain part of cases, which was endorsed by typical clinical symptoms and enzyme studies. 5) As the criterion of PRWP, V3R equal to or less than 3 mm was thought more adequate for higher specificity rather than 4 mm.

Inflammatory pseudotumor of the liver is a rare benign tumor with microscopic finding of fibrous stroma and chronic inflammatory cell infiltration. Predominance of plasma cells, histiocytes, lymphocytes, some eosinophils and whorled pattern of fibrosis is often characteristic. Due to similar radiologic appearance of hepatocellular carcinoma, inflammatory pseudotumor of the liver was often misdiagnosed and hepatic resection is often performed before preoperative tissue diagnosis. We report a case of inflammatory pseudotumor, which was a 47-year-old woman with fever, upper aMominal pain and weight loss, diagnosed by sonoguided liver biopsy and treated with antibiotic therapy only without surgery. After two weeks of treatment, the radiologic image of the mass was almost disappeared with improvement of previous symptoms. This opportunity and the possible effectiveness of antibiotic treatment should keep in mind in the differential diagnosis of the hepatic mass with similar radiologic appearance of hepatocellular carcinoma.

We report a case of Dirty Neck in a 27-year-old male suffering from severe atopic dermatitis. 'Dirty Neck', a reticulate pigmentation of the anterior and anterolateral aspects of the neck, is a specific finding in some subjects with atopic dermatitis. Two groups have been indentified. One is found in older patients with severe atopic dermatitis whose pigmentary lesions develop after puberty and show little seasonal variation. The other is found in younger patients with mild eczema who have a increase in pigment during the summer. Our patient showed a dark brown colored, linear, reticulate pigmentation of the neck, especially anterolateral aspeet regarded as the former group. More comprehensive and detailed clinical study is needed to evaluate the importanee of this entity in regard to as a minor clinical feature of Korean atopic dermatitis.

BACKGROUND AND OBJECTIVES: It has been reported that various inflammatory and immune reactions are involved in the development and progression of atherosclerosis. We tried to investigate whether the TNF receptor superfamilies are involved in the development and progression of atherosclerosis. MATERIALS AND METHOD: Thirteen carotid atheroma specimens(frozen sections : 10 cases, paraffin section : 5 cases) were obtained from the patients who underwent carotid endarterectomy at Samsung Medical Center and one normal aortic tissue was obtained from a transplantation donor in brain death. In the carotid endarterectomy specimens and a normal aortic tissue , the expressions of R110(TR1), 139(TR2) and DR3(TR3), members of the TNF receptor superfamilies were evaluated by immunohistochemical staining with monoclonal antibodies. Simultaneously, we evaluated the expressions of foam cells, smooth muscle cells, T-lymphocytes and B-lymphocytes. RESULTS: Immunohistochemical analysis identified a strong expressions of foam cells and smooth muscle cells in all atheroma. But, the expression of T-lymphocytes was minimal and that of B-lymphocytes was rare. The expression of DR3(TR3) was seen in all atheroma as strongly positive. The expression of 139(TR2) was observed well in frozen sections, but not in paraffin sections. Whereas, that of R110(TR1) was observed in paraffin sections as weakly positive, but not in frozen section. The areas where the TNF receptor superfamilies were expressed correlated to the area of foam cell presence. The expression of DR3 also correlated with expression of smooth muscle cells. In normal aortic tissue, the expression of inflammatory cells or TNF receptor superfamilies was not observed except smooth muscle cells which were observed in normal artery. CONCLUSION: Foam cells and smooth muscle cells were abundantly present in atheroma. The TNF receptor superfamilies are expressed in the atheroma and the region of expression was coincident with the presence of foam cells.

We report a case of sarcoidosis which developed in the skin, lung and eyes in a 50-year-old woman. The skin lesions showed two types of cutaneous manifestations which were subcutaneous nodules on her back and erytrematous papules on the face for several months. Our patient's seurm angiotensin converting enzyme (ACE) level was elevated at 33.5 IU/L(reference range, 8.3-21.4 IU/L) and the purified protein derivative(PPD) skin test had a negative result. On her roentgenographic examinations, we could find multiple nodular densities with hazziness on both her lungs and radionuclides(Gallium 67) uptakes in right lower lung field. The ratio of helper to suppressor T cells was 9 in bronchial lavage. Diagnosis of sarcoidosis was made on the basis of histologic findings of non-caseating granulomas from skin and lung tissue. Treatment was initiated with oral alternate-day prednisone 40mg. The cutaneous lesions and dyspnea improved in 2 and 4 weeks respectively, and serum ACE level returned to normal in 2 months.

BACKGROUND: Doxylamine succinate(DS) is an antihistamine commonly used as an over-the-counter medication to relieve insomnia and frequently involved in overdoses. Its overdoses are dominated by anticholinergic effect. Recently it was revealed that DS had a direct effect on muscle, while its exact mechanism is not clear yet. We evaluated the patients with rhabdomyolysis induced by DS overdose for patients disposition based upon clinical decision, especially by creatinine phosphokinase(CPK). METHODS: We reviewed retrospectively the medical records of patients admitted by DS overdose from Jan. 1998 to Oct. 1999. Seventy and nine cases of DS overdose were evaluated with respect to age and sex distribution, amount ingested, clinical symptomatology, time from ingestion to visit, pattern of CPK, amount of bicarbonate used as therapy, complication and prognosis, especially in patients complicated rhabdomyolysis. RESULTS: Rhabdomyolysis, diagnosed as more than 1,000I. U/L of CPK, has been noted in 25(31.6%) of 79 cases of DS overdose visited to our emergency department(ED). In patients diagnosed rhabdomyolysis, the number of man was 10 cases(40%) and the number aged between 20 and 40 years was 22 cases(88%). The average time from DS ingestion to ED visit was 459 minutes. The amount of DS ingested was 500-5,000mg(mean, 1,980mg). 13(52%) cases ingested less than 2,250mg of DS. The initial levels of CPK(range, 48-14900I. U/L; normal range, 26-200I. U/L) after admitting to our emergency department were normal in 15 cases(60%) of rhabdomyolysis patients. The range of peak CPK levels after ingestion was 607 to 412,500I. U/L(mean, 33,550I. U/L). Its peak time was 6 to 96 hours(mean, 28.96 hours). In 14 cases(67%) of 21 visiting within 24 hours after ingestion, peak time of CPK ranged 12 to 24 hours after ingestion. The amount of bicarbonate used as therapy of rhabdomyolysis ranged 100 to 2,740mEq(mean, 656mEq) and all patients was discharged after improvement without other complication including acute renal failure. CONCLUSIONS : Although patients ingested less than 2,250mg of DS, emergency physicians should observe them more than 24 hours after DS ingestion with CPK follow-up after gastric irrigation and charcoal administration.
