گلاس آینومرها موادی هستند که از ابتدای معرفی به عالم دندانپزشکی مورد بررسی های زیادی قرار گرفته اند. تحقیقات بر روی خصوصیات مکانیکی گلاس آینومرها، بعنوان یکی از ابتدایی ترین تست ها جهت بررسی کارایی کلینیکی این مواد همیشه مورد توجه بوده است. اخیرا در ایران نیز انواعی از گلاس آینومرهای کانونشنال و رزین مودی فاید شده در دسترس دندانپزشکان قرار گرفته است که بنظر می رسد تاکنون هیچگونه تحقیقی در مورد ...
BACKGROUND Necrotizing enterocolitis (NEC) is a major source of neonatal morbidity and mortality. Since there is no specific diagnostic test or risk of progression model available for NEC, the diagnosis and outcome prediction of NEC is made on clinical grounds. The objective in this study was to develop and validate new NEC scoring systems for automated staging and prognostic forecasting. STU...

BACKGROUND Necrotizing Enterocolitis (NEC) is the most common gastrointestinal emergency in neonates. Previously established risk factors for the development of NEC include prematurity and low birth weight. However, it is not clear to date as to whether the etiology of NEC is due to host, environmental, or yet other unknown factors. We analyzed the differences in incidence of NEC in twin pregna...
INTRODUCTION Necrotizing enterocolitis (NEC) affects 5-10% of infants born weighing less than 1500 g. Most models of NEC recapitulate late-stage disease with gut necrosis and elevated inflammatory mediators. Evaluation of NEC at earlier, less lethal stages of disease will allow investigation of initial disease triggers and may advance our understanding of temporal relationships between factors ...
BACKGROUND Eosinophils infiltrate intestinal tissue during necrotizing enterocolitis (NEC) and adult bowel diseases. We theorized that epithelial damage causes eosinophilic activation and recruitment at NEC onset. OBJECTIVE We studied the relationship between persistent blood eosinophilia and medical or surgical complications during NEC. METHODS NEC cases and controls at MU Children's Hospi...
OBJECTIVES To examine the variation in the incidence and to identify the timing of the presentation of necrotizing enterocolitis (NEC) in a cohort of preterm infants within the Canadian Neonatal Network (CNN). METHODS This was a population-based cohort of 16 669 infants with gestational age (GA) <33 weeks, admitted to 25 NICUs participating in the CNN between January 1, 2003, and December 31(...
BACKGROUND Intestinal stricture is an important complication of necrotising enterocolitis (NEC). We aimed to describe clinical profile and identify the risk factors for post-NEC intestinal strictures. METHOD A retrospective study of infants with NEC over 10 year period. RESULTS Of the 61 infants with NEC, 18 (29.5%) developed intestinal strictures. Leucocytosis and longer length of bowel re...
BACKGROUND Necrotizing enterocolitis (NEC) is a devastating intestinal disease that afflicts 10% of extremely preterm infants. The contribution of early intestinal colonization to NEC onset is not understood, and predictive biomarkers to guide prevention are lacking. We analyzed banked stool and urine samples collected prior to disease onset from infants <29 weeks gestational age, including 11 ...
