A Case of Gastric Anisakiasis with Recurrent Abdominal Pain in a Child / 대한소아소화기영양학회지

Anisakiasis is a accidental parasitic infection caused by nematode larvae belonging to the subfamily Anisakinae when a raw or inadequately cooked fish is ingested. The common clinical symptoms are severe colicky abdominal pain or epigastric full sensation, nausea, vomiting and fever, but hematemesis or melena is very rare. We report a case of a 11-year-old female child who developed severe epigastric pain recurrently for 2 months, and recalled that she had eaten the raw flesh of an Astroconger myriaster. Endoscopic examination showed the whitish worm invading the stomach wall. Clinical symptoms disappeared after endoscopic removal. This study may be the first pediatric case of gastric anisakiasis in korea.

A Clinical Study of Infective Endocarditis in Childhood / 소아과

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.

A Clinicopathological Study on the Prognosis of IgA Nephropathy in Children

PURPOSE: This study was performed to determine the natural history of histologically confirmed IgA nephropathy in pediatric patients who presented with hematuria and proteinuria. PATIENTS AND METHODS: We reviewed the clinical course of 57 patients diagnosed with IgA nephropathy at the age of 15 years or younger from 1981 to 2000. All patients presented with hematuria or minimal proteinuria( or =40 mg/m2/day), hypertension, and chronic renal failure. RESULTS: The mean age at presentation was 9.5+/-2.8 years(4 to 15 years) and 42(74%) were male. Isolated gross hematuria was observed in 20 patients(35%), microscopic hematuria in 3(5%), minimal proteinuria in 4(7%), both gross hematuria and minimal proteinuria in 15(26 %), and both microscopic hematuria and minimal proteinuria in 15(26%). During a median follow-up of 7.0+/-3.5 years, 38(67%) had complete resolution of hematuria and proteinuria, 12(21%) had persistently abnormal urinalysis without development of adverse events. Only 7(12%) developed adverse events:4(7%) developed severe proteinuria, 1(2%) became hypertensive, and 2(3%) developed impaired renal function. By univariate analysis using the chi-square test, the age at presentation(>10 years)(P<0.01) and poor histological classes of the Lee or Haas classification at onset(P<0.05) were significantly correlated with adverse events, whereas sex and clinical signs at onset were less concordant. CONCLUSION: We can conclude that the prognosis of IgA nephropathy diagnosed in early childhood is better and a good correlation exists between the clinical manifestations of this disease and the histological classes.
