Necrotizing enterocolitis (NEC) is a common and often fatal inflammatory disorder affecting preterm infants that develops upon interaction of indigenous bacteria with the premature intestine. We now demonstrate that the developing mouse intestine shows reciprocal patterns of expression of TLR4 and TLR9, the receptor for bacterial DNA (CpG-DNA). Using a novel ultrasound-guided in utero injection...

Perforated NEC in the fragile, premature infant remains a complex neonatal and surgical problem. Future investigation into the basic mechanisms of the intestinal inflammatory response in the premature neonate may allow for preventive strategies in the management of NEC. Until then, surgical management for perforated NEC will remain a necessary intervention to treat the complications of this dis...

Context: Necrotizing enterocolitis (NEC) remains one of the most common causes of morbidity and mortality for premature infants in the neonatal intensive care unit (NICU). Many theories concerning its pathophysiology and inciting factors have been suggested but progression in preventing the onset of NEC has been minimal. While this article highlights the pathophysiology, management, outcomes of...

Necrotizing enterocolitis is the leading cause of morbidity and mortality from gastrointestinal disease in premature infants and is characterized by initial feeding intolerance and abdominal distention followed by the rapid progression to coagulation necrosis of the intestine and death in many cases. Although the risk factors for NEC development remain well accepted, namely premature birth and ...

Few cases of neuroendocrine carcinoma (NEC) of the gallbladder (GB-NEC) have been reported. Data obtained from the 10 patients with GB-NEC treated in our hospital between January 2008 and December 2012 were retrospectively analyzed and compared with those of 377 patients with gallbladder adenocarcinoma. GB-NEC accounted for 2.2% of all gallbladder cancers. The patients (8 females and 2 males) w...

Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of prematurely born infants. Maternal milk plays an important protective role against NEC development and is the major source of epidermal growth factor (EGF) for neonates. The aim of this study was to examine the effect of orally administered EGF on the incidence of NEC in a neonatal rat model. Newborn rats were artifi...

Neuroendocrine carcinoma (NEC) of the esophagus and gastric cardia is a rare tumor, and the Chaoshan region has one of the highest incidences of esophageal and gastric cardia cancer (GCC) worldwide. The aim of this study was to characterize the clinicopathologic features of esophageal NEC (n = 67) and gastric cardia NEC (n = 13) cases identified over a 9-year period in the Chaoshan region. Esop...
