BACKGROUND: The stool color card has been the primary tool for identifying acholic stools in infants with biliary atresia (BA), in several countries. However, BA stools are not always acholic, as obliteration of the bile duct occurs gradually. This study aims to introduce Baby Poop (Baby unchi in Japanese), a free iPhone application, employing a detection algorithm to capture subtle differences in colors, even with non-acholic BA stools. METHODS: The application is designed for use by caregivers of infants aged approximately 2 weeks-1 month...

PURPOSE: Hepatobiliary scintigraphy (HBS) is used to aid in the diagnosis of Biliary Atresia in full-term infants with conjugated hyperbilirubinemia. There is little information on the utility of the HBS in premature infants with conjugated hyperbilirubinemia and infants with parenteral nutrition associated cholestasis (PNAC). The purpose of this study is to assess the utility of HBS in differentiating Biliary Atresia and PNAC in premature neonates and full-term infants who received parenteral nutrition (PN)...

Recent studies reported the important role of autophagy in follicular development. However, the underlying molecular mechanisms remain elusive. In this study, we investigated the effect of follicle-stimulating hormone (FSH) on mouse granulosa cells (MGCs). Results indicated that autophagy was induced by FSH, which is known to be the dominant hormone regulating follicular development and granulosa cell (GC) proliferation. The activation of mammalian target of rapamycin (mTOR), a master regulator of autophagy, was inhibited during the process of MGC autophagy...

Duplications of the gastric tract are made up of a wide variety of masses throughout the gastrointestinal tract. They may have tubular or cystic morphology. Some duplications are associated with malformations, especially those located in the thorax, which can be associated with intestinal atresia, and malformations of the urinary tract or vetebras (Lund. 2012).

Congenital cystic lung lesions are a group of rare pathologies that are usually diagnosed in the prenatal period. The majority of these lesions are diagnosed at pathology examination as congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestration (BPS). These lesions are typically managed by surgical intervention within the first year of life and have an excellent prognosis. We examined the evolution of imaging appearances from prenatal diagnosis to postnatal work-up of these lesions and correlate imaging and pathological findings...

BACKGROUND: Anastomotic stricture is the most common postoperative complication in infants undergoing repair of esophageal atresia with or without tracheoesophageal fistula (EA/TEF). Stricture indices (SIs) are used to predict infants at risk for stricture requiring dilation. We sought to determine the most accurate SI and optimal timing for predicting anastomotic dilation. MATERIALS AND METHODS: A retrospective study of infants undergoing repair of EA/TEF between 2008 and 2013 was performed...

Granulosa cells (GCs) play an important role in ovarian follicle growth, development, and follicular atresia. In the present study, we investigated the effects of Melatonin on bovine GCs, and asked if MTNR1A was involved in their response to this indole hormone. Our results indicated that Melatonin inhibited GC apoptosis by up-regulating the expression of BCL2, BCL-XL, GPX4, and SOD1, and down-regulating the expression of BAX, CASP3, and TP53. Moreover, Melatonin modulated bovine GC function by decreasing the expression of INHA, INHBB, FSHR, and TGFBR3, and the abundance of Inhibin β and Activin B, while increasing the expression of LHR, INHBA, and secretion of progesterone by GCs...

The aim of choanal atresia (CA) surgery is to achieve bilateral nasal patency. Among the different methods of CA repair, the endoscopic transnasal approach has gained recent popularity with the advent of endoscopic instruments and techniques. This article describes our experience regarding CA repair that was done either using or not using a stent in different periods of time in our department. Between February 2006 and February 2016, a total of 29 patients aged 2 days-53 years underwent endoscopic transnasal CA repair...

Microtia is a congenital auricular deformity that commonly presents with associated congenital aural atresia. The most acute concern in these patients is concomitant hearing loss at birth. A team-based approach by plastic surgeons and otologists is necessary to address both the otologic and audiologic concerns of microtia and atresia. Hearing rehabilitation is imperative; yet it should not compromise the aesthetic components of reconstruction and vice versa. Here, the authors propose a framework to evaluate and manage patients with microtia and atresia with the goal of optimizing functional and cosmetic outcomes...

Type I intestinal atresias (webs) are rare causes of gastrointestinal obstruction in infants, the most common site being the second portion of the duodenum. According to the Louw and Barnard classification, type 1 atresia has been defined as an intra-luminal web which results in either complete (web with no perforation) or incomplete (web with central perforation) intestinal obstruction. The jejunum is a rare site of such webs. Diagnosis of an incompletely obstructing web due to central perforation is usually difficult and challenging...

Mammalian fetal ovaries contain numerous primordial germ cells (PGCs), although few mature oocytes are obtained from females, owing to apoptosis and follicle atresia. The regulatory mechanisms underlying oogenesis/folliculogenesis remain unknown. Development of methods for obtaining mature oocytes from PGCs in fetal ovaries in vitro could contribute to clarifying these mechanisms. The failure of follicle assembly has been found to be the most challenging aspect in conventional culture conditions. Recently, we established novel culture conditions that enable successful follicle assembly, sustaining interactions between the oocyte and somatic cells, and, in turn, promoting oocyte growth and maturation...

Esophageal atresia (EA) is a rare anomaly that mandates surgical intervention. Patients with EA often have complicated medical courses due to both esophageal anomalies and related comorbidities. Although several prognostic classification systems have been developed to decrease the mortality rate in EA, most systems focus only on the influence of the major anomaly, and external risk factors that could be influenced by the neonatal caregivers to a certain extent are not included. The aim of this study was to investigate the risk factors for in-hospital mortality in neonates with EA and develop a scoring model to predict mortality...

BACKGROUND: Hypoplastic left heart syndrome (HLHS) covers a spectrum of rare congenital anomalies characterised by a non-apex forming left ventricle and stenosis/atresia of the mitral and aortic valves. Despite many studies, the causes of HLHS remain unclear and there are conflicting views regarding the role of flow, valvar or myocardial abnormalities in its pathogenesis, all of which were proposed prior to the description of the second heart field. Our aim was to re-evaluate the patterns of malformation in HLHS in relation to recognised cardiac progenitor populations, with a view to providing aetiologically useful sub-groupings for genomic studies...
