Mucoepidermoid carcinoma on the lip is a very rare disease, consisting of epidermoid and mucus-producing cells histologically. A 47 year old female had had an asymptomatic, palpable, bean-sized nodule on the center of her upper lip for 2 years. Histological findings showed multiple oval nests consisting of epidermoid & clear cells and cystic spaces filled with faintly eosinophilic amorphous material in a fibrotic background throughout the dermis, subcutis, and muscular layer After a diagnosis of mucoepidermoid carcinoma, Mohs micrographic surgery was performed for complete removal, and A - T flap with M plasty was designed for appropriate repair.

PURPOSE: This study was conducted to get baseline data to establish a guideline for the infant nutrition by observing the feeding practice and nutritional intake during infancy and evaluationg the nutritional status of iron and lipids at 12-month-old infants. METHODS: This survery was cnducted from July to November, 1992. Subjects were healthy infants who were brought to Yeungnam University Hospital for vaccination. We followed up feeding methods for 6 months in 120 infants, and laboratory tests which include hemoglobin, fematocrit, MCHC, ferritin, total cholesterol, HDL-cholesterol, triglyceride and urea nitrogen/creatinine ratio were done in 36 infants at 12 months of age. RESULTS: Male to female sex ratio was 1.6:1 in total 120 study infants. Among 36 infants who took laboratory tests, five infants were breast-fed, 25 were formula-fed, and 6 were mexed-fed. Percentage of the formula-fed infants increased as their monthly age increases. Although 54.2% of the studied infants were started weaning diet at four months of age, 10.8% of infants were not given any weaning diet until 6 month of age. Breastfed infnats had lower hemoglobin(10.6+/-1.8g/dl), hematocrit(32.6+/-3.6%), serum ferritin(13.6+/-13.1ng/ml)(p<0.05), and 15.6% of them had anemia and 16.7% of them had iron deficiency. Serum lipids levels except total cholesterol in breaset-fed female infants were comparable between groups. CONCLUSIONS: We confirm that the incidence of iron deficiency anemia was increased in breast fed infants and there was no difference in lipids levels according to different feeding methods. Adequate iron supplementation through weaning diets is one of the most important problems in breast milk feeding

Cecal volvulus is uncommon in pediatric patients and there are few reports of cecal volvulus with cerebral palsy. Here, we report the case of a 19-year-old male patient who presented with abdominal distension, a history of cerebral palsy, refractory epilepsy due to lissencephaly, and chronic constipation. An abdominal x-ray and computed tomography without contrast enhancement showed fixed dilated bowel intensity in the right lower abdomen. Despite decompression with gastric and rectal tube insertion, symptoms did not improve. The patient underwent an exploratory laparotomy that revealed cecal volvulus. Cecal volvulus usually occurs following intestinal malrotation or previous surgery. In this patient, however, intestinal distension accompanying mental disability and chronic constipation resulted in the development of cecal volvulus. We suggest that cecal and proximal large bowel volvulus should be considered in patients presenting with progressive abdominal distension combined with a history of neuro-developmental delay and constipation.

Econazole, a potent broad-spectrum antifungal agent and a Ca2+ channel antagonist, induces cytotoxicity in leukemia cells and is used for the treatment of skin infections. However, little is known about its cytotoxic effects on solid tumor cells. Here, we investigated the molecular mechanism underlying econazole-induced toxicity in vitro and evaluated its regulatory effect on the metastasis of gastric cancer cells. Using the gastric cancer cell lines AGS and SNU1 expressing wild-type p53 we demonstrated that econazole could significantly reduce cell viability and colony-forming (tumorigenesis) ability. Econazole induced G0/G1 phase arrest, promoted apoptosis, and effectively blocked proliferation- and survival-related signal transduction pathways in gastric cancer cells. In addition, econazole inhibited the secretion of matrix metalloproteinase- 2 (MMP-2) and MMP-9, which degrade the extracellular matrix and basement membrane. Econazole also effectively inhibited the metastasis of gastric cancer cells, as confirmed from cell invasion and wound healing assays. The protein level of p53 was significantly elevated after econazole treatment of AGS and SNU1 cells. However, apoptosis was blocked in econazole-treated cells exposed to a p53-specific small-interfering RNA to eliminate p53 expression. These results provide evidence that econazole could be repurposed to induce gastric cancer cell death and inhibit cancer invasion.

Mesenchymal cystic hamartoma of the lung is quite rare lesion which has an unknown prevalence, firstly described in 1986. It is characterized by multiple nodules and variable sized cysts in both lung field. The nodules of immature mesenchymal cells gradually enlarge and become cysts which are lined with normal or metaplastic respiratory epithelium and have the cambium layer of primitive mesenchymal cells. Main symptoms are hemoptysis, recurrent pneumothorax, and hemothorax. It is known to benign tumor, but has possibility of malignant degeneration. In gross findings in opertive field, multiple and variable-sized cystic lesions and nodules were observed. The cysts were lined with normal respiratory epithelium and had the cambium layer of primitive mesenchymal cell. Gross and microscopic findings were compatible with mesenchymal cystic hamartoma. We report a case of mesenchymal cystic hamartoma in a 27-year-old woman who had recurrent pneumothorax and hemoptysis.

BACKGROUND/AIMS: Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), troponin I, and high-sensitivity C-reactive protein (hs-CRP) are each associated with higher rates of death and recurrent myocardial ischemia in patients with acute coronary syndrome (ACS). We evaluated the prognostic value of NT-proBNP and a multi-marker risk approach with the simultaneous assessment of NT-proBNP, troponin I, and hs-CRP in patients with ACS. METHODS: We included 277 patients who were admitted for ACS between January and December 2006. We measured NT-proBNP, troponin I, and hs-CRP within 24 hours of the onset of symptoms. Patients were followed for a median of 559 days for cardiovascular events, including death, new myocardial infarction, heart failure, or rehospitalization for ACS. RESULTS: NT-proBNP was the most powerful predictor of clinical outcome among the biomarkers (HR 3.65, 95% CI 2.11-6.30), followed by the peak troponin I and hs-CRP (HR 2.08, 95% CI 1.12-3.87;HR 1.99, 95% CI 1.18-3.37, respectively), but not the baseline troponin I. A multi-marker risk approach with the simultaneous assessment of NT-proBNP, hs-CRP, and peak troponin I was significantly associated with cardiovascular events, especially the presence of three positive biomarkers (adjusted HR 4.20, 95% CI 1.39-12.67). CONCLUSIONS: NT-proBNP is the most powerful, independent predictor of clinical outcome among the cardiac biomarkers. Since the peak troponin I level provides more prognostic information than the baseline level, follow-up measurement of troponin I may be warranted for risk stratification. The multi-marker risk approach appears to have better prognostic performance than any marker in isolation.

To overcome the shortage of available organ in children, living-related liver transplantation(LRLT) has been introduced in Asan Medical Center since 1994. However, the use of graft livers across ABO blood groups is unavoidable since the organ donor is usually one of the recipient's parents in LRLT cases. In ABO-incompatible liver transplants from brain dead donors, the incidences of perioperative mortality, arterial thrombosis, and irreversible rejection and the rate of retransplantation have been reported to be greater. But recent reports from LRLT showed that 1-year survival rate of ABO incompatible cases were approximately 80%. So we started ABO incompatible LRLTs at our institute since Feb, 1996. Three cases of ABO incompatible LRLT have been performed thereafter, 2 with fulminant hepatitis and 1 with cirrhosis. Plasma pheresis or exchange transfusion was done to decrease isohemagglutinin perioperatively. Immunosuppression consisted of a quadruple-drug treatment in one, FK506 and steroid in two. The follow-up periods were 2, 4 and 13 months respectively. One child died of acute respiratory distress syndrome with normal graft function on 51st postoperative day. Two children are alive with good health, but one of them suffers S2 segment bile duct stricture, which is under the management with PTBD. The present results suggest that ABO incompatilbe LRLTs can be performed to overcome the shortage of the liver in children using a combination of the preioperative plasma pheresis and immunosuppression.

BACKGROUNDS: Living-donor liver transplantation (LDLT) has been established as an efficacious option to resolve the shortage of cadaveric donor organs for pediatric recipients. This surgical innovation has significantly reduced the pretransplantation mortality for children, but the crisis of increasing scarcity of donor organs in our hospital has led us to extend LDLT to adult recipients. However, the extension of LDLT from pediatric recipients to adult recipients has been made only with limited success largely because of the inability of a relatively small-size left-lobe graft to meet the metabolic demands of an adult recipient. It has been postulated that a left-lobe graft smaller than 40% of the recipient's standard liver volume will not result in a successful adult-to-adult LDLT in chronic parenchymal liver disease. METHODS: From February 1997 to October 1997, 10 LDLTs, using 9 extended left-lobe grafts and 1 right-lobe graft, were performed on patients with end-stage parenchymal liver diseases (9 cases of B-hepatitis-induced cirrhosis with or without an associated hepatocellular carcinoma and 1 case of alcoholic cirrhosis) at the Department of Surgery, Asan Medical Center. The ratios of the graft to the standard liver volume of the recipients were in the range of 30% to 55%. RESULTS: All grafts showed immediate function, but delayed normalization of the serum total bilirubin was demonstrated in all recipients receiving left-lobe grafts. There were no mortalities and serious complications in donors. Two recipients died of sepsis 21 days and 40 days after transplantation, and 8 recipients (80%) are alive with good liver function at a median follow-up of 5.1 months (range 2~10 months). CONCLUSIONS: The aim of this article is to report our experience with adult-to-adult LDLT shows that a graft size greater than 30% of the recipient's standard liver volume is able to meet the metabolic demands of adult recipients with chronic parenchymal liver disease and that LDLT might open a new donor pool for adult recipients when the supply of cadaveric organs is severely restricted.
