Infantile digital fibromatosis(IDF) is a rare, benign fibrous tumor, first described in 1965 by Reye. IDF may occur single or multiple lesions exclusively on the fingers or toes, rare occurrence outside the digit have been reported. This tumor grow slowly and may adhere to the deeper tissue, and may lead to deformity of the digit, but do not distant metastasis or dissemination. There is a marked tendency for recurrence after surgical excision. Up to now, only 6 cases have been reported in the literature showing spontaneous regression. We experienced a case of infantile digital fibromatosis located on hypothenar area at birth. Also that spontaneous regressed at 13 months of age. We reported a case of IDF showing spontaneous regression with brief review of related literature.

PURPOSE: The information in the internet is increasing and the number of people using the Internet to obtain medical information is increasing rapidly too. But, compared to the amount of information, the quality of information is extremely variable. To assess the accuracy of medical information on the Internet, the quality of information about food allergies available on the internet examined. METHODS: Online searches using the phrase "food allergy" were conducted on five major Internet search engines. The first 50 web pages generated by each engine were examined. Making an exception of the web pages which were inaccessible, irrelevant, and duplicated, sixty out of two hundred and fifty web pages were evaluated. Information scores were developed from 1(no statement) to 4 (sufficient) and designed to assess how well the web pages mentioned the summary, symptom, diagnosis, treatment, and education of the patients, and emergent management. RESULTS: When classified by ownership, there were six(10%) oriental clinics, twelve(20%) hospitals, twenty one(35%) profit-making institutions, fourteen(23%) non-profit institutions and seven others (12%). The mean information score(IS) was 10.7. Summary got the highest IS(2.25) and the education for patients and supporters got the lowest IS(1.33). Medical institutions such as hospital and clinic got 12.33 and non-medical institutions got 10.25. But there were no statistically significant differences between these two institutions(P=0.107). CONCLUSION: Overall, the quality of information on food allergy through the Internet was poor. The main reasons are unlimited listings of related information on the Internet and an absence of a reviewing process of the information. Therefore, people should not entirely rely on the Internet for medical information and medical-related institutions such as hospitals, schools, clinics and relevant academic associations should develop an Internet system to improve the quality of information.

The purpose of this study is to review the operative management and outcome of operation for Crohn's disease. The medical records of 17 patients who underwent operations due to Crohn's disease at Seoul National University Children's Hospital from January of 1988 to June of 2005 were reviewed and retrospective study was carried out. The male-to-female ratio was 1.8: 1. The median age at the onset of symptom and the time of diagnosis was 9 years 6 months and 11 years 6 months respectively. The median interval time from diagnosis to operation was 2 years and 1 month (0 month~8 years). Ileocolic or ileocecal region was the most common site of involvement. The indications of operation were intractable symptoms (8 cases) and obstruction or stricture (7 cases). The median postoperative hospitalized days were 14.4 days (8~35 days). Five patients (29%) experienced postoperative complications. Symptom free state or symptom relief was observed in 11 cases after surgery and 6 cases had wax and wane course of aggravation and improvement. In pediatric Crohn's disease patients who present with intractable symptoms despite medical treatment or develop surgical complications, symptom free state or symptom relief can be achieved by minimal resection of involved lesion.

Interferon-alpha is an established therapy for the patients with myeloproliferative disease. Unusual immune-mediated side effects have been reported during treatment. Among them, renal and cardiac toxicities are rare complications. Recently we experienced a case of hemolytic uremic syndome found in a 40-year old male undergoing interferon-alpha therapy for chronic myelogenous leukemia, chronic phase. On admission, his chief complaints were generalized edema and azotemia. Bone marrow biopsy revealed transformation into accelerated phase. bcl/abl gene was positive. Peripheral blood smear showed hemolytic anemia. Despite prompt diagnosis, institution of plasmapheresis, and steroid, his renal function did not recover, as expected. Hemolytic uremic syndrome was a chronic form of renal toxicity due to interferon-alpha. In this case, renal function did not recovered to normal level. However, early detection of renal toxicity such as proteinuria or acute tubular necrosis, and the discontinuation of interferon-alpha could achieve the recovery of normal renal function. Therefore, periodic examination of renal function should be performed in the patients with the use of long-term interferon-alpha.

PURPOSE: The objective of the present study was to histologically evaluate durability and bone regeneration capacity of new synthetic membranes in comparison to clinically available collagen membrane. MATERIAL AND METHODS: To the skulls of 12 rabbits, we created 4 bone defects of 6 mm in diameter on each of them. Each of defects were covered with at least one of 5 membranes: No membrane, Collagen (Ossix(TM)), PLGA, HA-coated-PLGA and HA-PLGA/PLGA. After 4, 8, 12 weeks, we cut the skulls and dyed with H-E. And then, the histologic observation was done. RESULTS: In current study, the control group which did not use the membrane showed bone regeneration at 12 weeks and covered the bone defect partially. New bones were formed through the underneath of endocranium, and the upper defect was filled with connective tissues and fats. Collagen membrane (Ossix(TM)) showed new bones after 4 weeks, and they were formed through the membrane which maintained until 12 weeks. PLGA, HA-coated-PLGA, HA-PLGA/PLGA showed bone regeneration after 4 weeks and after 8 weeks, they mostly filled defects. At 12 weeks, we could find new bones and previous bones almost look alike and also, they united well. Membranes were unnoticeable after 4 weeks and were absorbed. CONCLUSION: Bone formation and maturation of PLGA, HA-coated-PLGA and HA-PLGA/PLGA were faster than the control group. They showed no difference on the application of HA and after 4 weeks, they were absorbed.

BACKGROUND: We experienced an outbreak of typhoid fever in Chunju area which manifested as severe symptoms and signs, and variable complications. To chracterize the epidemic and to identify a possible source of infection, the clinical findings of patients from the outbreak were analyzed, and the patterns of antimicrobial susceptibility and phage typing of Salmonella Typhi isolates were determined. METHODS: We analyzed a total of 232 patients from the outbreak who admitted to Chunju Presbyterian Medical Center during 1996 August through October. The medical records of the patients were reviewed retrospectively. All isolates of S. Typhi from the outbreak were analyzed for serotyping, antibiogram, and phage typing. Phage typing were performed using Vi- phages for 50 strains isolated from the patients who showed atypical clinical manifestations and unusal complications. RESULTS: The outbreak attacked mainly young femalegroup. The complications observed were: 155 casesof hepatitis, 47 pancytopenia, 20 acute pancreatitis, 13 urinary tract infection, 12 intestinal hemorrhage, 5 disseminated intravascular coagulation, 4 meningitis, 3 septic shock, 2 sensorineural hearing loss, 2 myocardial ischemia, 2 pneumonia, 1 stillbirth, and 1 death. S. Typhi were isolated in 129 cases including 111 from blood, 17 stool and 1 urine. All isolates were susceptible to all antimicrobial agents tested. All 50 isolates from severe patients with unusal complications were identified as Salmonella, serogroup D1, serotype Typhi, phage type D1. CONCLUSIONS: We experienced an outbreak of typhoid fever associated with severe, atypical symptoms and unusual complications, caused by Salmonella, serogroup D1, serotype Typhi, phage type D1.

BACKGROUND/AIMS: The Barrett's esophagus is confirmed by performing a biopsy when the gastroesophageal junction (GEJ) and Z-line do not coincide. In Japan, the GEJ is at the distal end of the palisading vessel while Western countries define it as the proximal tip of the gastric fold. However, there is little data on the prevalence of an endoscopic Barrett's esophagus and the inter-observer variation. METHODS: Four experienced endoscopists reviewed the endoscopic still images of 111 consecutive patients. The level of inter-observer agreement was expressed as a kappa value. RESULTS: The average percentage of patients with an endoscopically confirmed esophagus was 34.2%. The level of inter-observer agreement was substantial (kappa=0.698). CONCLUSIONS: The prevalence of an endoscopic confirmed Barrett's esophagus was high, and the inter-observer variation was substantial when the GEJ was defined as the distal end of the palisading vessel. Considering the low incidence of esophageal adenocarcinoma and the risk of hemorrhage from a biopsy, a more specific marker is needed in this high-risk group.

BACKGROUND/AIMS: There are a limited number of studies concerning the outcomes of diverticulitis in the Oriental population. We sought to evaluate the clinical features and the long-term outcomes of diverticulitis in Korean patients. METHODS: We retrospectively reviewed the clinical courses of 104 patients (59 men, 45 women; median age 48.5 years [range: 24-83 years]) hospitalized for their first episode of diverticulitis between 1989 and 2005. RESULTS: Right-sided diverticulitis was more common (71/104, 68%). However, the proportion of left-sided diverticulitis increased as age increased. Thirty-two patients underwent operations: 30 because of complications and 2 because of presumed appendicitis. Left-sided diverticulitis was an independent risk factor for complications (OR=7.6, p<0.001), and it required surgical treatment more often than right-sided diverticulitis did (61% vs. 17%, p<0.001). Eighty-five patients were followed for a median of 36 months. Four of the 62 medically treated patients developed recurrence of diverticulitis, with a 3-year cumulative recurrence rate of 4.8%. None of the 4 recurrences showed complications, and all were successfully managed using conservative treatment. No predictive factors for the recurrence of diverticulitis could be determined. CONCLUSIONS: The recurrence rate and risk of complications associated with recurrence are low in patients treated conservatively for the first episode of diverticulitis. Therefore, elective surgery to prevent recurrence and complications should be utilized sparingly in patients with diverticulitis.
