Authors present two casas of familial metaphyseal dysplasia which was first described by Pyle as a skeletal disorder affecting the metaphyseal region of tubular bones. The cases reported here bear some resemblance to that of Bawkin and Krida.

Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.

Two common gastrointestinal cancers, namely, gastric and colorectal cancers, cause high mortality and morbidity. The development of gastrointestinal cancers usually follows stepwise processes with recognizable pre-neoplastic changes. A class of noncoding RNA known as microRNA (miRNA) is increasingly recognized to play pleiotropic functions in the multistep development of gastrointestinal cancers. Abnormal patterns of miRNA expression in gastric and colorectal cancers have been widely reported. These dysregulated miRNAs function as novel proto-oncogenes and tumor-suppressor genes by controlling cellular malignant phenotypes, including unchecked cell proliferation, resistance to apoptosis, enhanced invasiveness and metastasis, and angiogenesis. Moreover, certain polymorphisms in miRNA genes or miRNA-binding sites are associated with disease risks whereas detection of circulating or fecal miRNAs may facilitate early diagnosis. The prognostic functions of a number of dysregulated miRNAs in gastrointestinal cancers have also been established. Delineating the pathophysiological basis of miRNA dysregulation will further our understanding of the pathogenesis of these two potentially fatal diseases. Such efforts will also result in the development of miRNA-based biomarkers and therapeutics for the risk stratification, diagnosis, prognostication, and treatment of gastrointestinal cancers.

Artificial intelligence (AI) is coming to medicine in a big wave. From making diagnosis in various medical conditions, following the latest advancements in scientific literature, suggesting appropriate therapies, to predicting prognosis and outcome of diseases and conditions, AI is offering unprecedented possibilities to improve care for patients. Gastroenterology is a field that AI can make a significant impact. This is partly because the diagnosis of gastrointestinal conditions relies a lot on image-based investigations and procedures (endoscopy and radiology). AI-assisted image analysis can make accurate assessment and provide more information than conventional analysis. AI integration of genomic, epigenetic, and metagenomic data may offer new classifications of gastrointestinal cancers and suggest optimal personalized treatments. In managing relapsing and remitting diseases such as inflammatory bowel disease, irritable bowel syndrome, and peptic ulcer bleeding, convoluted neural network may formulate models to predict disease outcome, enhancing treatment efficacy. AI and surgical robots can also assist surgeons in conducting gastrointestinal operations. While the advancement and new opportunities are exciting, the responsibility and liability issues of AI-assisted diagnosis and management need much deliberations.

Many patients undergoing vitrectomy due to proliferative diabetic retinopathy also have diabetic ephropathy.Hence, to figure out the surgi-cal results of vitrectomy and the survival rate after vitrectomy in diabetic patients having diabetic nephropathy, we reviewed medical records of 70 patients[83 eyes]who had been followed for 3 months or longer after vitrectomy. Among them, 28 patients[33 eyes]were complicated by diabetic nephropathy.Visual acuity improved in 21 out of 33 eyes [63.6%]among the patients with nephropathy while vision improved in 29 out of 50 eyes[58.0%] among those without nephropathy.The two groups showed significant improvement of visual acuity postoperatively and the difference in visual acuity improvement between two groups was not statistically significant. The factors which affected postoperative visual acuity improvements in patients with diabetic nephropathy were preoperative panretinal photocoagulation[p=0.013]and intraoperative intraocular silicone oil injection[p=0.021]. Rate of occurrence of complications after vitrectomy and the types of the complications were similar in the two groups. During the 4-year follow up, 4 of 11 patients who had been on peritoneal dialysis or emodialysis died. These results showed that the result of vitrectomy for proliferative diabetic retinopathy in patients with iabetic nephropathy was not poor and suggested that diabetic nephropathy might not be a contraindication of vitrectomy for proliferative diabetic retinopathy.
