Septic encephalopathy is defined as brain dysfunction secondary to sepsis. It occurs in septic patients as a manifestation of multi-organ dysfunction. Without evidence of intracranial infection, various extracranial infections causing severe sepsis may induce septic encephalopathy. We report a patient with septic encephalopathy complicating acute appendicitis. Initially, the patient presented with impaired mental state and raised liver enzymes.

Actinomyces are anaerobic, Gram-positive bacteria that are part of the endogenous flora of mucous membranes in humans. Infection caused by these bacteria is termed actinomycosis. The 3 most common types of actinomycosis are cervicofacial, abdominopelvic, and pulmonary. A previously healthy 6-year-old boy presented with the emergency room with fever, vomiting, and abdominal pain and initially diagnosed with acute appendicitis. Exploratory laparoscopy was done. Histologic finding demonstrated acute gangrenous appendicitis complicated by perforation and sulfur granules compatible with actinomycosis. Subsequently, he was diagnosed with abdominal actinomycosis and received long-term antibiotic therapy. Abdominal actinomycosis is uncommon in children and difficult to diagnose because of its nonspecific symptoms and of difficulties in growing Actinomyces in the clinical setting. It is necessary to include abdominal actinomycosis as a differential diagnosis of children presenting with abdominal pain.

Purpose: The ultrasonography (USG) and computed tomography (CT) are popular diagnostic tools for the diagnosis of acute appendicitis in children, but there are many debates about their clinical significance. The purpose of this study is to clarify the clinical significance of USG, CT and follow-up CT performed subsequently to USG, especially in perforated acute appendicitis in children. Methods: We have reviewed 419 cases of surgically confirmed acute appendicitis in children under the age of sixteen, who had been treated in Inje University Ilsan Paik Hospital from March 2002 to February 2006. All the clinical data including the results of USG and CT were collected and analyzed. Results: Sensitivity, specificity, positive and negative predictive values of USG were 98.7%, 96.8%, 98.1%, 97.8% in non-perforation group and 90.8%, 100%, 100%, 81.9% in perforation group. Those of CT were 96.4%, 100%, 100%, 96.5% and 86.6%, 100%, 100%, 87.5% respectively. Those of follow-up CT after USG were 100%, 100%, 100%, 100% and 87.5%, 100%, 100%, 92.0% respectively. The duration of using antibiotics in seven patients showed positive correlation with the interval between two imaging studies (r=0.0472, p=0.019). There was no statistical significance of correlation when these imaging studies performed within 30 hours together. Conclusion: In most of the cases, single choice between USG and CT would be enough to diagnose the acute appendicitis in children. But, it may be helpful to perform CT as early as possible subsequently to USG when there is discrepancy between initial USG and clinical impression.

Staphylococcus epidermidis is a normal inhabitant of skin, throat, mouth, vagina, and urethra. It is not usually pathogenic, particularly in immunocompetent hosts. This report describes a case of a pyogenic liver abscess caused by Staphylococcus epidermidis in a healthy 12-year-old boy. He was admitted to Seoul St. Mary's Hospital with intermittent fever for 6 days. Findings on abdominal computed tomography (CT) showed a mass measuring $7.0{\times}6.5$ cm in the right hepatic lobe. Culture of the abscess resulted in growth of Staphylococcus epidermidis as a causative organism. The patient was successfully treated with intravenous administration of antibiotics and percutaneous drainage of the abscess.

While various examples of rationale or benefits of ascariasis control could justify a necessity of control activity in a community, few practical index other than the e99 Prevalence or intensity of infection has been used to evaluate the efficacy obtained by the control activity. A literature-based retrospective study was undertaken to provide some numerical data on the decreasing morbidity of surgical ascariasis as a consequence of ascariasis control in Korea. A thorough review of literatures (1959∼1990) on biliary and other surgical complications of ascariasis reported from general hospitals revealed that their incidence has been decreasing very proportionally to the national figures of its e99 Prevalence and worm burden. For example, according to the remarkable decreases of the prevalence of ascariasis, there is an evident decreasing tendency of the proportion(%) of ciliary ascariasis cases among all biliary surgical patients and the proportion of biliary ascariasis cases among all biliary stone patients in general hospitals. It is highly suggested that the Korean people have been much benefited by the control activity of ascariasis executed at a national scale since 1960s, especially in terms of incidence of biliary and other surgical complications of ascariasis.

Kawasaki disease (KD) is an acute, systemic inflammatory disorder that often targets coronary arteries. Being the common cause of acquired heart disease in children, timely diagnosis and intravenous immunoglobulin treatment are crucial. However, it is challenging for physicians to diagnose KD if it presents with atypical manifestations. We report the case of a 5-year-old boy who initially presented with appendicitis; after an appendectomy, he had a prolonged fever. He was finally diagnosed with atypical KD and successfully recovered after intravenous immunoglobulin treatment. Through a literature review, we found 21 cases of appendicitis associated with KD. In most cases, the patients were male with a mean age of 5.3 years. Most had higher proportions of incomplete KD and coronary artery complications than expected for typical KD. In conclusion, appendicitis could be a rare complication of KD; therefore, multidisciplinary cooperation and early recognition of atypical KD are essential for timely diagnosis.

Purpose : Hemolytic uremic syndrome(HUS), known as a most common cause of childhood renal failure in western countries, has been a relatively rare disease in Korea. Although the reported cases were not related to any specific cause in Korea, there was an outbreak of HUS with bloody diarrhea in Japan last year. We report here that we experienced the several typical HUS last year. Patients : From Jan.1996 to Dec. 1996, five patients were diagnosed as HUS at Samsung Seoul Medical Center, Dept. Pediatrics. Results : 1) The age of onset was below 3 years in 3 cases and above 9 years in 2 cases. 2) All the cases happened between summer and autumn. Three patients had domestic travel and 4 patients drank well or spring water before the symptoms. 3) The clinical manifestation was generalized edema, oliguria, anuria and hematuria. The bloody diarrhea were present in 5 cases and 1 patient had operation with the impression of appendicitis. 4) There was no bacteria which was isolated from the blood or stool samples. 5) Renal biopsies were performed in 2 cases, because of protracted clinical course. One showed microthrombotic angiopathy and the other cortical necrosis with necrotizing glomeruli. 6) Complete recovery was the outcome in 4 cases and one case progressed to chronic renal failure. Conclusion : In conclusion, typical HUS associated with bloody diarrhea, epidemic and good prognosis can be found in Korea and careful surveillance of the pre-clinical cases will be necessary.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous palpable purpura, gastrointestinal(GI) symptoms, arthritis and renal involvement. In general, the prognosis is determined by GI complication as well as the severity of nephritis. In this study, we analyzed the statistical relationship between the GI symptom and other clinical findings for assessing the prognosis, and evaluated abdominal ultrasonographic findings for early diagnosis of this disease with atypical clinical presentation and early detection of serious GI complications. Methods : One hundred seventy seven patients with HSP in the Department of Pediatrics, Wonkwang University Hospital from January 1994 to June 2004, were enrolled. We retrospectively analyzed charts about clinical and abdominal ultrasonographic findings, and classified our patients into two groups(GI-Sx(-), GI-Sx(+)) for statistical analysis. Results : The ratio of female to male is 1.5 : 1. The peak age incidence was five to eight years in 95 cases(53%). The GI symptoms appeared in 117 cases(66%), which include abdominal pain 115 (98 %), tenderness 45(38%), nausea and vomiting 35(30%), bloody stool 10(8.5%), diarrhea four(3.4%), rebound tenderness four(3.4%), and also intussusception and appendicitis were complicated in five and two cases respectively. GI-Sx(+) group had an increased risk of renal involvement and relapse than the GI-Sx(-) group. But there were no relationships about sex and age incidence, or other clinical and laboratory findings between two groups. Ultrasonographic findings in 98 patients with GI symptoms included small bowel thickening in 70 cases(71%) in which duodenum, jejunum and ileum were involved in 71%, 45.7%, 40% respectively, small bowel dilatation in 41 cases(42%), lymph node swelling in 46 cases(47%), and ascites in 25 cases(25.5%). Conclusion : GI symptoms in patients with HSP suggested increased risk of renal involvement and relapse. Abdominal ultrasonography could be helpful in the early diagnosis on atypical clinical presentation and early detection of serious GI complication in these patients.
