Neurofibromatosis type 1 (NF1; also known as von Recklinghausen's neurofibromatosis) is inherited in an autosomal dominant fashion, although it can also arise due to spontaneous mutation. Gastrointestinal involvement of NF1 is seen in 10% to 25% and causes symptoms in fewer than 5%. Histologically, the gastro intestinal (GI) manifestation of NF1 occurs in three forms: hyperplasia of the gut neural tissue, stromal tumors, and duodenal or periampullary endocrine tumors. A 31-year-old female, diagnosed with NF1, presented with poor oral intake and vomiting for 10 days prior to admission. Preoperative gastrofiberscopic finding was gastric outlet obstructing polypoid duodenal bulb lesion. The patient underwent hemigastrectomy with antecolic gastrojejunostomy due to gastric outlet obstruction. The final pathologic report was submucosal neurofibromatous proliferation with Brunner's gland hyperplasia located at the duodenal bulb in the NF1 patient. We report this case with a review of literatures.

Gastric tuberculosis is a rare disease. It usually occurs secondarily to another lesions and mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion locates in the lesser curvature side of the antrum. Therefore the clinical picture is similar to the peptic ulcer. A 24-year-old women visited to the Inha university hospital complaining of vomiting and epigastric discomfort. Gastrofiberscopy showed multiple polypoid mass around the pylorus with stenotic pyloric channel. Subtotal gastrectomy was performed and histologic examination revealed chronic granulomatous inflammation with caseation necrosis. That is compatible with tuberculosis. The patient was taken antituberculosis medication without complication. So we report the case of pyloric obstruction due to gastric tuberculosis with review of the literature.

Total anomalous pulmonary venous confluence(TAPC), a rare cyanotic congenital anomaly of the heart especially in adult, is now diagnosed by echocardiography instead of cardiac catheterization with high sensitivity and specificity. The key points are identification of pulmonary veins, pulmonary venous confluence draining anomalously to the heart. RVDVO on M-mode, abnormal echo free space posterior to left atrium on 2D-echo are basic characteristics of TAPVC. Peak velocity and flow profile measurement on the doppler provide additional informations : obstruction and anomalous vessels. A case of 23 year old male with supracardiac type TAPVC diagnosed by echocardiography was corrected successfully by surgery.

We saw a case of minoxidil induced pericardial effusion in a 36 years old female who developed generalized edema, weakness and hypertrichosis after taking minoxidil for 1 year. Her chest PA showed globular shaped cardiac enlargement and pulmonary congestion. Echocardiography of the heart showed moderate amount of pericardial effusion. 10 days later after cessation of the drug administration and conservative managements, her chest PA showed marked improvement of heart size and pulmonary congestion. 20 days later her blood pressure became normal with the continued use of other antihypertensive drugs.

Three-dimensional (3D) tissue/organ printing is a major aspect of recent innovation in the field of tissue engineering and regenerative medicine. 3D tissue/organ printing aims to create 3D living tissue/organ analogues, and have evolved along with advances in 3D printing techniques. A diverse range of computer-aided 3D printing techniques have been applied to dispose living cells together with biomaterials and supporting biochemical factors within pre-designed 3D tissue/organ analogues. Recent developments in printable biomaterials, such as decellularized extracellular matrix bio-inks have enabled improvements in the functionality of the resulting 3D tissue/organ analogues. Here, we provide an overview of the 3D printing techniques and biomaterials that have been used, including the development of 3D tissue/organ analogues. In addition, in vitro models are described, and future perspectives in 3D tissue/organ printing are identified.

Double primary cancer of the stomach and esophagus has been revealed a very low incidence in the world except Japan and reported only 6 cases in Korea. Furthermore, it is difficult to manage this type of double cancer because esophageal cancer has a biologic tendency to early metastasis. This paper is concerned with a case of double primary cancer, which we have synchroniously confi~rmed esophageal squamous cell carcinoma and gastric adenocarcinoma with gastrofiberscopic biopsy, and then treated them by radical resec tion and systemic chemotherapy.

PURPOSE: The purpose of this study was to investigate the stress distribution in mandibular implant-supported overdentures and tooth-supported overdentures with telescopic crowns. MATERIALS AND METHODS: The assumption of this study was that there were 2, 3, 4 natural teeth and implants which are located in the second premolar and canine regions in various distributed conditions. The mandible, teeth (or implants and abutments), and connectors are modeled, and analyzed with the commercial software, ANSYS Version 10.1. Stress distribution was evaluated under 150 N vertical load bilaterally on 3 experimental conditions - between canine areas, canine and 2nd premolars, 10 mm posterior to 2nd premolars. RESULTS: Overall, the case of the implant group showed more stress than the case of the teeth group in stress distribution to bone. In stress distribution to superstructures of tooth and implants, there was no significant difference between TH group and IM group and the highest stress appeared in TH-IV and IM-IV. The stress caused from bar was much higher than those of implant and tooth. TH group showed less stress than IM group in stress distribution to abutment teeth and implant. CONCLUSION: The results shows that it is crucial to make sure that distance between impact loading point and abutment tooth does not get too far apart, and if it does, it is at best to set abutment tooth on premolar tooth region. It will be necessary to conduct more experiments on effects on implants, natural teeth and bone, in order to apply these results to a clinical treatment.
