Inflammatory bowel disease (IBD) is regarded as one of the risk factors for colorectal cancer, and early detection of cancer in these patients may be difficult, especially in pediatric patients. Prognosis of pediatric colorectal cancer is known to be poor, because of delayed diagnosis and unfavorable differentiation. We report a case of a pediatric patient with a 10-year history of ulcerative colitis who was diagnosed with sigmoid colon cancer when he was 15 years old. He underwent proctocolectomy with ileal pouch anal anastomosis. Postoperative pathological examination of the tumor revealed adenocarcinoma. The pericolic tissue layer was infiltrated, but metastases were not found in either of the two lymph nodes. Children with a long history of predisposing factors such as IBD need particular attention to the possibility of colorectal cancer. Early diagnosis through regular screening with colonoscopy is one of the most important critical factors for a good prognosis.

AIM:To evaluate the epidemiologic features of young age gastric cancer(GC). METHODS:Retrospectively,a total of 3242 patients with GC between 18 and 45 years of age and 3000 sex-and age-matched controls were *** subjects were stratified into 3 groups based on age (A,18-30 years;B,31-40 years;C,41-45 years). Epidemiologic characteristics and risk factors were investigated with reference to their age and gender. RESULTS:Compared to controls,more frequent intake of high risk diet(P=0.00075),history of heavy smoking(P=0.00087),intake of heavy alcohol(P= 0.00091),lower social economic status(P=0.00083), body mass index>30(P=0.00097),urban residence(P=0.00065),and more frequent exposure to harmful occupational environments(P=0.00072)were observed in all age groups and both genders in young age *** relationships were weaker in females compared to males of the same age,and were stronger as the age of patients ***,in group C of young age GC patients,environmental factors played important roles in females and males with a similar body *** females,older age at first delivery(> 35 years),lack of lactation history,nulliparity,and poor nutritional status during pregnancy were significantly associated with an increased risk of GC(P=0.00034). In this study,252 patients(7.8%)had a family history of GC with high odds ratio(OR)(3.22-4.21).In particular, family history was more closely associated with GC in males(OR,4.21 in male vs 3.46 in female)and more advanced cases(P=0.00051). CONCLUSION:Hormonal associated factors were more commonly associated with females whereas environmental factors were more commonly associated with males in young age GC patients.

3 D printing is a method of rapid prototyping and manufacturing in which materials are deposited onto one another in layers to produce a three-dimensional object. Although 3 D printing was developed in the 1980 s and the technology has found widespread industrial applications for production from automotive parts to machine tools,its application in pharmaceutical area is still limited. However,the potential of 3 D printing in the pharmaceutical industry is now being recognized. The ability of 3 D printing to produce medications to exact specifications tailored to the needs of individual patients has indicated the possibility of developing personalized medicines. The technology allows dosage forms to be precisely printed in various shapes,sizes and textures that are difficult to produce using traditional techniques. However,there are various challenges associated with the proper application of3 D printing in the pharmaceutical sector which should be overcome to exploit the scope of this technology. In this review,an overview is provided on the various 3 D printing technologies used in fabrication of complex dosage forms along with their feasibility and limitations.

AIM： To investigate endoscopic and clinicopathologic characteristics of early gastric cancer （EGC） according to microsatellite instability phenotype. METHODS： Data were retrospectively collected from a single tertiary referral center. Of 981 EGC patients surgically treated between December 2003 and October 2007, 73 consecutive EGC patients with two or more microsatellite instability （MSI） mutation [high MSI （MSI-H）] and 146 consecutive EGC patients with one or no MSI mutation （non-MSI-H） were selected. The endoscopic and clinicopathologic features were compared between the MSI-H and non-MSI-H EGC ***： In terms of endoscopic characteristics, MSI-H EGCs more frequently presented with elevated pattern （OR 4.38, 95% Cl： 2.40-8.01, P 〈 0.001）, moderate- to-severe atrophy in the surrounding mucosa （OR 1.91, 95% CI： 1.05-3.47, P = 0.033）, antral location （OR 3.99, 95% CI： 2.12-7.52, P 〈 0.001） and synchronous le- sions, compared to non-MSI-H EGCs （OR 2.65, 95% CI： 1.16-6.07, P = 0.021）. Other significant clinicopatholog- ic characteristics of MSI-H EGC included predominance of female sex （OR 2.77, 95% CI： 1.53-4.99, P 〈 0.001）, older age （〉 70 years）（OR 3.30, 95% CI： 1.57-6.92, P = 0.002）, better histologic differentiation （OR 2.35, 95% Cl： 1.27-4.34, P = 0.007）, intestinal type by Lau- ren classification （OR 2.34, 95% CI： 1.15-4.76, P = 0.019）, absence of a signet ring cell component （OR 2.44, 95% CI： 1.02-5.86, P = 0.046）, presence of mu- cinous component （OR 5.06, 95% Cl： 1.27-20.17, P = 0.022）, moderate-to-severe lymphoid stromal reaction （OR 3.95, 95% CI： 1.59-9.80, P = 0.003）, and co-exist- ing underlying adenoma （OR 2.66, 95% CI： 1.43-4.95, P = 0.002）. CONCLUSION： MSI-H EGC is associated with unique endoscopic and clinicopathologic characteristics includ- ing frequent presentation in protruded type, co-exist- ing underlying adenoma, and synchronous lesions.

Endoscopic ultrasound (EUS) has emerged as a valuable tool in the evaluation of benign and malignant pancreatic diseases. The ability to obtain high quality images and perform fine-needle aspiration (FNA) has led EUS to become the diagnostic test of choice when evaluating the pancreas. This article will review the role of EUS in benign pancreatic diseases.
