The effectiveness and factors influencing frequency of endoscopic bougie dilatation in treating postoperative anastomotic stenosis of congenital esophageal atresia.

Objective: This study is to evaluate the effectiveness and frequency factors of endoscopic bougie dilatation in treating postoperative anastomotic stenosis of congenital esophageal atresia (CEA).

Methods: The clinical data of patients of anastomotic stenosis with endoscopic bougie were retrospectively analyzed. According to the number of dilation times (ND), patients were divided into two groups (Group 0: ND < 3; Grooup1: ND ≥ 3), and the differences in multiple clinical data were compared.

Current status of fecal calprotectin as a diagnostic or monitoring biomarker for cow's milk protein allergy in children: a scoping review.

Background: There are few approved biomarkers for diagnosis and monitoring of cow's milk protein allergy (CMPA), thus the oral food challenge remains to be the golden diagnostic standard. A potential biomarker is fecal calprotectin, a cytosolic protein, elevating in the presence of intestinal mucosal inflammation. We aimed to undertake a scoping review of the evidence pertaining to the current status of fecal calprotectin used for diagnosis and monitoring CMPA in children, and tried to indicate the aspects needed to be concerned in the future investigations and researches.

From SARS to COVID-19: What we have learned about children infected with COVID-19.

Introduction: Coronaviruses, both SARS-CoV and SARS-CoV-2, first appeared in China. They have certain biological, epidemiological and pathological similarities. To date, research has shown that their genes exhibit 79% of identical sequences and the receptor-binding domain structure is also very similar.

Objective: To investigate the epidemiological and clinical features of calicivirus-associated diarrhea in hospitalized children in Chengdu, China in recent years.

Methods: The clinical data of 267 children with calicivirus-associated diarrhea aged <5 years who were hospitalized in Chengdu Women and Children's Central Hospital (the only sentinel hospital for sample collection of pediatric viral diarrhea in Chengdu, Sichuan) between January 2012 and December 2014 were retrospectively studied.

[Molecular epidemiology of viral diarrhea in Chengdu infants and young children].

Objective: To investigated the molecular epidemiologic features of viral diarrhea in Chengdu infants and young children, and to establish baseline patterns of etiology, provides the scientific basis for the vaccine development and the epidemic situation control.

Methods: From March, 2006 to December, 2008, a total of 376 infants and young children from Chengdu area hospitalized for diarrhea in Chengdu Children's Hospital were enrolled in this study. The stool specimen collected from each patient was tested for rotavirus (RV), Calicivirus (CV), astrovirus (AstV) and adenovirus (Adv) by using enzyme linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) examination.
