We reviewed the 43 medical records of patients with cellulitis or erysipelas who had been admitted at the depar1ment of dermatology of Seoul National University Hospital and followed them up for mean 21.6 months. The results were as follows. 1. The sex ratio of patients with cellulitis was 1:1.4 and the average age was 49 years. 2. The lower extremity as the most frequently invloved site of cellulitis with the frequency of 58.1% (25 cases), with the head and neck being involved in 16 cases(37.2%) and trunk and upper extremity in 1 case each(2.3% ). 3. The portals of infecticin were suspected in 33 cases(76% ), where tinea pedis was detect,ed in 18 cases(41.9%), previous skin infeection 10 cases(23.3%) and trauma in 9 cases(20.9%). 4. Initial systemic symptoms were fever(76.7%), chill(65.1%) and headache(37.2%). Erythema(100%), local heating(90,7%), tenderness(88.4%), swelling(86.0%), ulcer(16.3%), bulla(14.0%), lymphangitis(9.2%) and lymphadenit,is(9.2%) were found in the skin lesions. 5. The laboratory findings revealed leukocytosis in 35.7%, elevaed ESR in 86.8% positive 6. ASO titer in 63.0% and positive CRP in 80%, Microorganism. were detected in only 1 of 15 blood cultures, in 2 of 4 bulla fluid cultures and in 7 of 9 bus cultures. There was no growth of causative microorganisms in 3 tissue cultures and 9 saline needle aspiration cultures. Penicillin was used as primary antibiotics in 19 cases, which changed to another antibiotics due to lack of improvement in 3 cases and cefazolin was used in 21 cases, which changed in 2 cases due to the same reason. 7. Average admission priod was 11 days(range from 3 to 20 days) and 30.2% of patients wit.h cellulitis experienced recurrence, but 48% on low extrernity in contrast with 6.7% on head and neck.

The diagnosis of acute pancreatitis occurred in CAPD patients is quite difficult due to its clinical similarity with acute peritonitis. Delayed diagnosis and treatment of acute pancreatitis in CAPD patients may result in fatal complication. We experienced a case of acute pancreatitis in a CAPD patient. A 62 years old female visited the hospital with acute abdominal pain and cloudy effluent for 3 days. She has been on CAPD for 3 years and had two episodes of peritonitis at 6 months and 1 year before the admission. The causative organism was Streptococcus viridans in each episode. The peritonitis symptoms and peritoneal leukocyte count incresed despite of using Vancomycin(R) and Netilmicin(R). Causative organism was not isolated from dialysis. Serum amylase concentrations increased from 105mg/dL at the admission to 1,052mg/dL on day 10 of admission. Abdominal ultrasonography and abdominal computerized tomogram revealed fat infiltration, focal necrosis and multiple cyst formation at pancreas area. Computerized tomogram guided aspiration cytology revealed acute inflammation and necrosis. Bacteria were not found in the aspirate. Clinical symptoms were improved after discontinuation of CAPD and intraperitoneal use of antibiotics. The patient restarted CAPD on the day 18 and remained without complications. We report this case with a brief review of literatures.

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood, representing 4 to 8% of all malignant tumors in children below 15 years old, but rhabdomyosarcoma of the paratesticular region is rare. The paratesticular rhabdomyosarcoma is a highly malignant lesion with early invasion and metastasis, which has retroperitoneal metastases in about half of the patients at time of diagnosis. However, the survival rates have been improved greatly by using multimodal therapy. We are submitting a case of paratesticular rhabdomyosarcoma with retroperitoneal lymph node metastasis with review of literatures.

Pediatric infection with Helicobacter pylori may occur early in childhood and persist lifelong. Global pediatric clinical studies have reported a decreasing tendency in the overall rate of H. pylori eradication. In pediatric patients with H. pylori infection, pediatric patients with peptic ulcer, and the first-degree relatives of patients with a history of gastric cancer, it is commonly recommended that H. pylori strains be eradicated. Antibiotic drug resistance to H. pylori, which has been reported to vary widely between geographic regions, is mainly associated with treatment failure in these patients. It is therefore imperative that the antibiotic resistance rates of H. pylori in children and adolescents be meticulously monitored across countries and throughout geographic regions. This paper particularly focuses on the antibiotic drug resistance of H. pylori and the thearpy of pediatric H. pylori infection cases.

OBJECTIVE: The purpose of this study was to analyze the stress distribution and the displacement pattern of mandibular anterior teeth under various intrusive force vectors according to the position of orthodontic miniscrews and hooks, using three-dimensional finite element analysis. METHODS: A three-dimensional finite element model was constructed to simulate mandibular teeth, periodontal ligament, and alveolar bone. The displacement of individual tooth on three-dimensional planes and the von Mises stress distribution were compared when various intrusion force vectors were applied. RESULTS: Intrusive forces applied to 4 mandibular anterior teeth largely resulted in remarkable labial tipping of the segment according to the miniscrew position. All 6 mandibular anterior teeth were labially tipped and the stress concentrated on the labiogingival area by intrusive force from miniscrews placed mesial to the canine. The distointrusive force vector led to pure intrusion and the stress was evenly distributed in the whole periodontal ligament when the hook was placed between the central and lateral incisors and the miniscrew was placed distal to the canine. CONCLUSIONS: Within the limits of this study, it can be concluded that predictable pure intrusion of the 6 anterior teeth segment may be accomplished using miniscrews placed distal to the canine and hooks located between the central and lateral incisors.

BACKGROUND: Soon Chun Hyang University Hospital emergency laboratory introduced Cobas(R) 6000 (Roche Diagnostics, Switzerland) to improve the turnaround time of emergency chemistry tests at peak time period. METHODS: For the designated period, before and after introduction of Cobas(R) 6000 the numbers of tests and test time were compared and we analyzed the process of the tests using Workflow simulator (Roche Diagnostics). RESULTS: The numbers of tests of 8 days (every Monday and Thursday) in June, 2007 and 2008 were 22,902 and 27,384. The mean test time of the 8 days in June, 2007 and 2008 were 13 min 41 sec and 12 min 22 sec. In 2007, increased mean test time was due to prolongation of waiting times in rotor within equipment for tests at peak time period. CONCLUSIONS: Using Cobas(R) 6000, the numbers of tests were increased at peak time period but mean test time was reduced, which made physicians and laboratory all satisfied.

Down syndrome is a rare cause of neonatal cholestasis. Neonatal cholestasis in a patient with Down syndrome is usually associated with severe liver diseases, such as neonatal hemochromatosis, myeloproliferative disorder and intrahepatic bile duct paucity. We experienced a case of idiopathic neonatal cholestasis in a patient with Down syndrome, which resolved spontaneously.

There is a wide variety of genital abnormalities observed in patients with Denys-Drash syndrome (DDS). WT1 is thought to influence the genes related to genital development and mutations in this gene have been associated with DDS. DDS should be considered in the differential diagnosis of newborns with genital anomalies. In contrast to other conditions with 46,XY disorders of sex development, individuals with DDS often have duplicated genital organs (a double vagina, cervix or uterus). A double uterus has not yet been reported with 1390G>A (Arg464 Asn) mutation. However, duplicated genitals have been reported with other genetic mutations in patients with DDS. The duplicated genitals in DDS may be associated with low anti-Mullerian hormone (AMH) secretion. Measurement of the AMH levels may add to our understanding of variations in genital development and their abnormalities in disorders such as DDS. In conclusion, this is first case of low level of AMH and double uterus in 1390G>A (Arg464 Asn) mutations of DDS male.

Atretic cephalocele is a degenerative form of encephalocele, which is detected as a cystic mass in the head, primarily in infants. Its presentation and prognosis vary and depend on various factors, including the nature of the tissues within the cyst, other concomitant anomalies, the site of development, and the presence or absence of an embryonic straight sinus. We here report 2 cases of atretic encephalocele, that were transferred to our hospital because round tumors, misdiagnosed as dermoid cysts, were detected in their parietal lobes immediately after birth. On diagnostic and differential MRI, an embryonic straight sinus was detected while histochemical results indicated that the lesions contained cerebral tissues. Despite these structural anomalies, the two patients developed normally neurologically and no other anomalies were detected. We here discuss these two cases and present a review of the relevant literature.

The prognosis of ovarian cancer remains poor, and there is a need to identifiy patients who are less likely to respond to treatment, in the hope that the identification of these patients with a poorer prognosis may allow the administration of more intensive or different treatment. But, most clinical and pathological factors were considered to lack satisfactory predictive power. Recently, essential role of protease in tumor cell invasion and metastasis have been elucidated in tumor biology. Urokinase-type plasminogen activator (uPA) and its inhibitor, plasminogen activator inhibitor-1 (PAI-1), play a key role in tumor-associated proteolysis. Thus, the presence of both uPA and PAI-1 modulates the invasive and metastatic phenotype of cancer cells. Genetically, nm23 protein from chromosome 17q may act independently as a metastasis suppressor. The purpose of this study was to determine the relative predictive power of some of those prognostic variables such as uPA, PAI-1 and nm23 protein in a selected group of patients of ovarian cancer. Immunohistochemical staining was used to determine the overexpression of uPA, PAI-1 and nm23 protein. Specimens were rated positive and negative. Then, scored '1' in case of positive for uPA, PAI-1, and negative for nm23, and '0' in case of negative for uPA, PAI-1, and positive for nm23, respectively. The sum of scores were divided into three groups (I, II and III groups), and compared with clinico-pathologic parameters, clinical response, lymph node metastasis, recurrence and 5-year survival rate, retrospectively. In univariate analysis, the positive rate of uPA was 36% (29/80), that of PAI-1 was 35% (28/80), and the negative rate of nm23 was 43% (34/80). The overexpression of uPA was higher in the low-grade tumor (p=0.0053), the overexpression of PAI-1 was positively correlated with the advanced stage of tumor (p=0.0001), more malignant histologic type (serous) of tumor (p=0.0013) and larger residual tumor mass (>2 cm)(p=0.0480). The overexpression of nm23 protein was negatively correlated with advanced stage of tumor (p=0.0068) and low-grade tumor (p=0.011). In scoring system, the number of patients with first group (I: score 0) was 24, II group (score: 1~2) was 49, and III group (score: 3) was 7. The mean age of patients was 46.4 years and mean follow-up time was 59 months. The rate of lymph node metastasis were 16.7%, 37%, and 75% respectively(p=0.0632). With increasing score in each group, the less clinical response rate was found (75% vs 71% vs 29%, p=0.0532). The 5-year survival rate of each group were 70% in I group, 65% in II group, and 14% in III group(p=0.0096). In conclusion, the scoring system using immunohistochemical staining with rating of overexpression uPA, PAI-1 and nm23 protein may be useful as an important and powerful predictive prognostic indicator in patients with epithelial ovarian cancer.
