BACKGROUND/AIMS Although gastric hyperplastic polyps are usually considered as benign lesions, a low risk of carcinomatous conversion is currently recognized. We aimed to identify the characteristics of hyperplastic polyps undergoing neoplastic transformation. METHODS A total of 269 gastric hyperplastic polyps from 216 patients removed by endoscopic polypectomy (EP) or surgical resection were...

INTRODUCTION Achieving profound pulpal anesthesia can be difficult in patients with symptomatic irreversible pulpitis. This study provides a systematic review and meta-analysis to address the population, intervention, comparison, outcome (PICO) question: in adults with symptomatic irreversible pulpitis who are undergoing endodontic treatment, what is the comparative efficacy of articaine compar...

Human tumor syndromes are usually caused by inherited or de novo mutations in tumor suppressor genes or oncogenes within the cells that give rise to the tumors [1,2]. In some occasions, the cells that give rise to tumors do not have intrinsic abnormalities in cell differentiation or proliferation but are forced into a hyperplastic state secondarily by neural or humoral factors. The latter pheno...

Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...

INTRODUCTION Hyperplastic pulpitis (pulp polyp) tissues contains cells with stem cell properties similar to that of the dental pulp stem cells (DPSCs). It has also been shown that CD146 enrichment can homogenize the cultures of DPSCs and enhance the colony forming potentials of their cultures. This study determines whether CD146 enrichment can help purifying the stem cells from heterogeneous cu...

Recent studies have suggested that hyperplastic polyps may be benign precursor lesions for a distinct subset of colorectal tumors. We conducted a clinic-based case-control study to evaluate risk factors for hyperplastic polyps. Cases with hyperplastic polyps (n = 219), adenomas (n = 437), and both types of polyps (n = 138), along with colonoscopy-negative controls (n = 708), were identified at ...

ity of nonfundic gland gastric polyps found incidentally at endoscopy [1]. Ma− lignant transformation has been reported in hyperplastic polyps but invasive carci− noma is rare [2]. A 63−year−old female was referred for routine screening colonoscopy and eso− phagogastroduodenoscopy because of pernicious anemia diagnosed 10 years previously. Upper gastrointestinal endos− copy revealed a 3 cm beni...
