Newborns with ileal atresia frequently present with abdominal distension, bilious vomiting, and failure to pass meconium. Diagnosis is usually established on plain x-ray of the abdomen by the findings of distended small bowel loops and air-fluid levels. In the period of October 1988 to February 1994, 8 patients with congenital ileal atresia were operated and the following results were obtained. 1. Eight patients were comprise of 4 males and 4 females, the ratio of male and female was 1 : 1. 2. Six patients(75%) had been admitted to our hospital during three days of life. 3. Congenital ileal atresia was in 8 cases : Type I in two(25%), Type II in two(25%), Type III a in three(37.5%), Type III b in one(12.5%). 4. There was one premature patient who was small for gestational age. 5. Overall, abdominal distension and bilious vomiting occurring in seven patients, were frequent presenting complaints. 6. Diagnosis was possible with clinical symptom and simple abdomen. 7. Operative treatment was undertaken as soon as the diagnosis was made. In seven cases a primary end-to-end anastomosis was performed after resection of dilated proximal loop. 8. A total of four associated congenital anomalies were found in one patient. 9. Postoperative complications occurred in three cases(37.5%).

Among the erythrocyte membrane defects, hereditary spherocytosis is the most common. The erythrocyte membrane defect results from a deficiency of spectrin, the most important structural protein in red cell. Hereditary spherocytosis often presents with hemolytic anemia, jaundice, moderate splenomegaly. Diagnosis is established by the presence of spherocytes in the peripheral blood, reticulocytosis, an increased osmotic fragility, and a negative Coombs test. In children, splenectomy is usually performed after age 6 years but can be done at a younger age if warranted by the severity of the anemia and the need for frequent transfusions. In the period December 1987 to Agust 1993, 9 patients with hereditrary spherocytosis underwent splenectomy and the following results were obtained. 1. Nine patients were comprised of five males and four females. 2. Five patients(55.6%) had been admitted to our hospital during age 6-10 years. 3. Four of the nine patients had autosomal dominant inheritance with variable expression. The other five patients had no known inheritance. 4. The diagnosis of the spherocytosis was based on the increased osmotic fragility and increased autohemolysis of the erythrocytes, as well as on the appearance of spherocytes in the peripheral blood smear. 5. In all cases splenectomy was performed. Two patients had concomitant gall stones and choledocholithiasis, respectively. One patient with concomitant gall stones underwent simultaneous cholecystectomy and splenectomy. The other patients associated with choledocholithiasis underwent splenectomy, cholecystectomy, choledocholithotomy, and T-tube drainage. 6. Complete hematologic recovery was obtained by the splenectomy in all cases. 7. Postoperative complication was not occurred.

PURPOSE: Allelic loss on chromosome 18q is a hallmark of presence of a tummor represser gene. Recently, DPC4 (deleted in pancreatic carcinoma, locus 4), a candidate tumor suppressor gene, has been localized at 18q21. Inactivation of DPC4 gene was reported in pancreatic carcinomas, coloretal carcinomas, and prostatic carcinomas. The aim of the present study was to determine if it might be altered in stomach cancer. MATERIALS AND METHODS: We tested for DPC4 gene mutations and allelic status at 18q21 using a modified 'cold SSCP' method in 48 primary gastric carcinoma and correlated the findings with various clinicopathologic characteristics of the patients. RESULTS: The frequency of mutations in primary gastric cancer was 27.1% (13/48). Mutations of exon 1, 8, 10 were found in 2 (4.1%), 4 (8.2%) and 7 cases (14.6%), respectively. DNA sequencing of 13 cases with DPC4 mutations identified six cases (46.1%) with substitution, four cases with deletion (30.7%), and two cases (23.1%) with insertion. No significant difference was observed in the frequency of DPC4 mutations in terms of other various clinicopathologic characteristics. CONCLUSION: These findings suggest that DPC4 mutations may play a significant role in the establishment and progression of the primary gastric cancer.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective resuscitative modality to temporize noncompressible truncal hemorrhage. Confirming the proper position of the balloon catheter in the target aortic zone is vital. Currently, there is a need for nonradiographical methods. This would overcome the drawbacks of conventional imaging modalities, such as fluoroscopy. Several studies have suggested ultrasound-guided visualization via subxiphoid, transperitoneal, or transesophageal views as an alternative to conventional imaging methods. However, such views are easily obscured in emergency settings. Herein, we report the case of a 70-year-old patient who was successfully resuscitated by REBOA under the guidance of transsplenic ultrasound. REBOA was safely performed using transsplenic visualization without fluoroscopy.

Background and Objectives: This study aimed to describe the ischemic stroke subtypes and risk factors in young Korean adults, focusing mainly on traditional risk factors and management of ischemic stroke. Methods: The study patients were the fi rst-ever acute cerebral ischemic infarction age 49 years or below admitted to the Kyung Hee University Medical Centre from September 2003 to June 2009, with ischaemic stroke patients >50 years as control. The stroke subtypes was categorized according to Trial of Org 10172 in Acute Stroke Treatment classifi cation. The traditional risk factors of ischemic stroke were examined. For those known to have hypertension and diabetes prior to onset of stroke, their adherence to treatment of hypertension and diabetes was also assessed. Results: Close to half of the patients ≤49 years were due to premature atherosclerosis from small vessel occlusion and large artery atherosclerosis. The most common risk factor in declining order was hypertension, smoking, dyslipidemia and obesity. On logistic regression analysis, hypertension, dyslipidemia, and obesity were strongly associated with small vessel occlusion. In patients who were known to have hypertension and diabetes prior to the onset of stroke, the younger patients were less adherent to the treatment as primary prevention than the older stroke patients. Conclusion: This study suggests that premature atherosclerosis from small vessel occulusion is the most common cause of ischaemic stroke among young adults in Korea. Non-adherence to primary preventive treatment of hypertension and diabetes is common.

BACKGROUND: Phyllodes tumors are relatively rare fibroepithelial tumors of the breast. There are no strict criteria for the classification of benign and malignant phyllodes tumor. The recurrence rate is relatively high, and no single criterion for predicting recurrence has yet been established. In an attempt to define the clinical features and their histopathological correlations, we have reviewed a total of 38 patients with original pathological diagnoses of cystosarcoma phyllodes and phyllodes tumors. METHODS: Thirty-eight cases of phyllodes tumors were reviewed. Microscopic slides were re-examined and reclassified using newly defined histologic criteria which were modified from those of Pietruszka et al. The pathologic criteria examined were the number of mitoses, the invasiveness of the tumor border, the stromal overgrowth, and the stromal cellular pleomorphism. The clinical features evaluated included age, incidence, clinical manifestation, surgical procedure, and recurrence. RESULTS: The mean age was 34.9 +/- 12.4 years with the peak age between 40 and 49. The yearly incidence trend showed a slow increase. Twenty-three tumors (62%) fullfilled the criteria for benign phyllodes tumors, seven tumors (19%) were borderline, and seven tumors (19%) were malignant. The mean ages of the patients with benign, borderline, and malignant phyllodes tumors were 31.9, 39.1, and 40.9 years, respectively. The sizes of the benign phyllodes tumors were smaller than those of the borderline or the malignant tumors. Recurrence was found after initial excision in two patients with benign phyllodes tumors. However, after an initial wide excision, there was no recurrence in five patients with borderline and malignant tumors. CONCLUSIONS: There were no dependable histopathological features to predict recurrence; that is, histologic type does not influence the rate of recurrence or the prognosis after an adequate excision.

To elucidate the effects of food texture such as hardness, cohesiveness, adhesiveness on mastication procedure, the electromyographic activity (EMG) of the masticatory muscles and the chewing movements were analyzed in eighteen young subjects during ordinary chewing. Seven different foods were selected by sensory texture profiling and mechanical test with texturometer; egg white, sausage, pizza cheese, yang-geng, biscuit, peanut and almond. The indexes of jaw movements used were the chewing number, chewing time, maximum opening, average opening, closing velocity and opening velocity. The EMG indexes analyzed were maximum and average integrated amplitude of the anterior temporal and masseter muscles. The results obtained were as follows. 1. The chewing time and chewing number, mandibular displacement and mandibular movement velocity were not changed by the hardness, cohesiveness and adhesiveness of the food (p>0.05). 2. The harder food materials showed a higher amplitude of the anterior temporal muscle integrated EMGs than the softer ones (p<0.05). 3. The maximum and average integrated EMGs of the masseter muscle increased with the increase of hardness of the food (p<0.05). 4. The integrated EMGs of preferred side and non-preferred side masticatory muscles increased with the increase of hardness of the food (p<0.05). 5. The adhesiveness and cohesiveness of the food were not the determining factor to the integrated EMGs of masticatory muscles (p<0.05).

The purpose of this study was to compare and evaluate the stress distribution and displacement developed in the abutment teeth and residual ridge area by madibular unilateral distal extension removable partial denture with 2 different retainer designs. The retainers on right and left canine and right 2nd molar were Akers clasp in one model and telescopic crown in the other model. The stress distribution of abutment teeth and residual ridge area on two model were compared and analyzed with 3-dimensional finite element method. 150N and 400N forces were applied vertically, 30 degree and horizontally on the central fossa area of left 1st molar of the removable partial denture, and then stress distribution patterns were analyzed and compared. The results were as follows 1. As the magnitude and angulation of applied force were increased, the magnitude of stress on the right and central residual ridge area and the right canine of the telescopic type increased and comparing to those of the Akers clasp type. 2. As the magnitude and angulation of applied force were increased, the mesial direction of displacement on the right residual ridge area and the right tooth of the telescopic type increased and the distal direction of displacement on left residual ridge area and the left canine increased comparing to those of Akers clasp type. 3. As the vertical force was applied, the distal direction of the displacement of the right tooth were greater and that of the left canine was smaller and the upward displacement of the right canine was greater in telescopic partial denture than those of Akers clasp type. 4. As the 30 degree force was applied, the mesial direction of the displacement of the right tooth were greater and the distal direction of the displacement of the left canine was smaller and the upward displacement of the right canine was greater in telescopic partial denture than those of Akers clasp type. In the horizontal force the results were same in right area tooth but the distal direction of displacement was greater in left canine. 5. In both removable partial dentures, as the magnitude and degree of force were increased, the stress and displacement were increased. The compressive force was dominative than the tensile force. 6. In both removable partial dentures, the magnitude of stress was greater on mucosal tissue area than that of the alveolar bone area on distal extension residual ridge area but the result was reversed on anterior residual ridge area. The displacement was always greater on mucosal tissue area than that of alveolar bone area.
