PURPOSE: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. METHODS: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. RESULTS: The 37 patients had a mean age of 5.4+/-4.8 months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was 4.3+/-0.8 months, and for those with typical and atypical CMPIE, and PROC and GERA were 3.8+/-4.6, 10.4+/-3.8, 3.4+/-3.9 and 7.8+/-5.7 months, respectively (p<0.05). The period from onset of symptom to diagnosis was 2.4+/-3.3 (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. CONCLUSION: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.

The purpose of the present study was to examine the effects of water extracts from red pepper seeds powder on antioxidative enzyme activities and oxidative damage in groups of rrats fed high-fat and high-cholesterol diets group (HFC). The Rrats were divided into the following five experimental groups which are : composed ofa normal diet group, a high fat.high cholesterol diet group, and a high fat.high cholesterol diet group supplemented with different amounts contents (1%, 2% and 4%) of red pepper seeds powder water extracts supplemented groups (HFCW1, HFCW2 and HFCW4, respectively). Body weight gains and food intake were lower ofin the red pepper seed water extracts groups were lower than those inof the HFC group. Hepartic xanthine oxidase (XOD) activity was decreased in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic glutathione peroxidase (GSH-px) activitiyactivity was increased in the HFCW4 group compared to the HFC group. Hepatic superoxide radicals within the mitochondria and microsomes of cells were significantly reduced in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic hydrogen peroxide in the cytosol was significantly reduced in the HFCW3 and HFCW4 groups compared to the HFC group. Hepatic carbonyl values in the microsomes and mitochondria were significantly reduced in the HFCW4 group compared to the HFC group. Hepartic thiobarbituric acid reaction substance (TBARS) activity was decreased in the HFCW2 group compared to the HFC group. These results suggest that water extracts of red pepper seeds powder may reduce oxidative damage by activation of antioxidative defense systems in rats fed high fat.high cholesterol diets.

Streptococcal myositis is an extremely uncommon infectious disease that is caused by Group A Streptococcus (GAS). A GAS infection spreads rapidly and diffusely through the muscle, resulting in edema and necrosis. This can lead to streptococcal toxic shock syndrome with an extremely hig mortality. We report a 42 year-old female patient with Streptococcal myositis accompanying with systemic lupus erythematosus who initially presented with fever, severe pain, and tenderness on the calf without any prodromal symptom of myositis. Despite the aggressive management, her general symptoms were aggravated and she died 7 days later as result of the toxic shock syndrome.

Ischemic colitis primarily affects the elderly with underlying disease, but it rarely occurs in young adults with risk factors, such as coagulopathy or vascular disorder. Moreover, it is extremely rare in the very young without risk factors. This paper presents a patient with ischemic colitis associated with heat stroke and rhabdomyolysis after intense exercise under high-temperature conditions. A 20-year-old man presented with mental deterioration after a vigorous soccer game for more than 30 minutes in sweltering weather. He also presented with hematochezia with abdominal pain. The laboratory tests revealed the following: AST 515 U/L, ALT 269 U/L, creatine kinase 23,181 U/L, BUN 29.1 mg/dL, creatinine 1.55 mg/dL, and red blood cell >50/high-power field in urine analysis. Sigmoidoscopy showed ischemic changes at the rectum and rectosigmoid junction. A diagnosis of ischemic colitis and rhabdomyolysis was made, and the patient recovered after conservative and fluid therapy. This case showed that a diagnosis of ischemic colitis should be considered in patients who present with abdominal pain and bloody diarrhea after intense exercise, and appropriate treatment should be initiated immediately.

PURPOSE: Advances in the treatment of congenital heart disease and a decline in the incidence of rheumatic fever has led to changes in the causative organisms and the clinical outcome of infective endocarditis(IE). We sought to analyze the clinical outcome, prognostic factors, causative organisms and corresponding antibiotic sensitivity in IE. METHODS: Retrospective analysis of medical records of 104 children diagnosed and treated with IE at Severance Hospital, Yonsei University College of Medicine from January 1986 to June 2003 was undertaken. According to the Duke criteria, 55 patients were classified into the definite group(DG) and possible group(PG). RESULTS: Thirty one cases(56.4%) fulfilled the criteria for the definite group in the Duke criteria, whereas 24 cases(43.6%) fulfilled the criteria for the possible group. The most common chief complaint on admission was fever(93%). The most common infecting organism was Staphylococcus aureus, which was found in 14 cases(48.3%). Three cases(21.4%) of this organism were methicillin- resistant S. aureus(MRSA). Other causative organisms were alpha-streptococcus(seven cases, 24.1%), Staphylococcus epidermidis(three cases, 10.3%), Citrobacter freundii(one case, 3.8%), Enterococcus faecium(one case, 3.4%) and Candida albicans(three cases, 10.3%). Penicillin-resistant organisms were found in 90.5%(19/21) of total cases and the most sensitive antibiotics were vancomycin(13/13, 100 %) and teicoplanin(12/12, 100%). One case of IE due to MRSA unresponsive to vancomycin was treated with Arbekacin. CONCLUSION: The incidence of IE caused by S. aureus, especially MRSA, is increasing. Multi-drug resistant organisms are also emerging as a frequent cause of IE. Thus, in patients strongly suspected of having IE in patients with underlying heart disease, glycopeptides such as vancomycin combined with aminoglycosides should be considered, and if fever and positive blood cultures continue despite treatment with glycopeptides, a consideration of the use of new antibiotics may improve the treatment results.

Neovascularization of the adventitial vasa vasorum with extension into the intima of atherosclerotic lesions is frequently observed, but its pathophysiological significance is still subject to debate. Recently, leptin, the product of the Ob gene, was identified. Leptin, via activation of the endothelial receptor (Ob-R), generates a growth signal involving a tyrosine kinase-dependent intracellular pathway and promotes angiogenic processes. We hypothesized that a high concentration of leptin within vasa vasorum and plaque itself, may influence inflammatory and vascular neovascularization coupling with functional upregulation of the vascular endothelial growth factor (VEGF). Microscopic computerized tomography was utilized for the spatial distribution of vasa vasorum and intimal neovascularization from atherosclerotic human coronary arteries. Atherosclerotic coronary arteries showed a dense plexus of microvessels in the adventitia and plaque itself. Microscopic analysis from human atherosclerotic aortas revealed an increase in the intimal thickness with neovascularization. The immunoreactivity for Ob-R, VEGF and matrix metalloproteinase (MMP) increased in atherosclerotic plaque, predominantly in the endothelial lining of the intimal neovessel and macrophages/foam cells. Our observation of a prominent colocalization between Ob-R, VEGF and MMP supports this hypothesis and these factors participate in the neovascularization of atherosclerotic lesions. The present study is the first report on vascular tissue and it opens a promising perspective concerning future investigations of leptin-dependent modulation of atherogenesis and vascular neovascularization under pathophysiolgical conditions.
