Infant Midnasal Stenosis: Reliability of Nasal Metrics HEAD & NECK

BACKGROUND AND PURPOSE: Midnasal stenosis is a poorly defined entity that may be a component of other conditions of nasal obstruction contributing to respiratory distress in infants. We sought to establish whether midnasal vault narrowing is a component of well-defined syndromes of nasal narrowing, such as bilateral choanal atresia and pyriform aperture stenosis, and to characterize the nasal anatomy of patients with syndromic craniosynostosis. MATERIALS AND METHODS: A convenience sample of patients with pyriform aperture stenosis, bilateral choanal atresia, and Apert and Crouzon syndromes with maxillofacial CT scans was identified. Patients with Pierre Robin Sequence were used as controls. Nasal measurements were performed at the pyriform aperture, choana, and defined midnasal points on axial and coronal CT scans. Intra- and interrater reliability was quantified with the intraclass correlation coefficient. T tests with Bonferroni adjustment were used to assess differences from controls. RESULTS: The study included 50 patients: Eleven had pyriform aperture stenosis, 10 had Apert and Crouzon syndromes, 9 had choanal atresia, and 20 were controls. Measurements in patients with pyriform aperture stenosis and Apert and Crouzon syndromes were narrower than those of controls at all measured points (P

ConclusionsFontan patients commonly have chronotropic incompetence, diminished heart rate reserve but with preserved heart rate recovery. While there is overall no difference in chronotropy in Fontan patients based on dominant systemic ventricle, there is a difference between HLHS and tricuspid atresia patients.

Biliary atresia (BA) is a fatal condition resulting in the lack of effective biliary drainage leading invariably to liver failure and cirrhosis within a year, and it is often lethal within a few months in the absence of corrective surgery or liver transplantation. In fact, BA is the most common indication for pediatric liver transplantation. Herein, we present a rare case of unexpected infant death due to BA diagnosed only postmortem in a context of child neglect and carelessness on the part of the parents. It emerged from the clinical history that after a few months, the parents no longer took their daughter to any medic...

Mutations in the tetratricopeptide repeat domain 7A gene (TTC7A) cause intestinal epithelial and immune defects. Patients can become immune deficient and develop apoptotic enterocolitis, multiple intestinal atresia, and recurrent intestinal stenosis. The intestinal disease in patients with TTC7A deficiency is severe, untreatable, and recurs despite resection or allogeneic hematopoietic stem cell transplant. We screened drugs for those that prevent apoptosis of in cells with TTC7A deficiency and tested their effects in an animal model of the disease.

Olayade, Adesoji Ademuyiwa, Ozor Ifezue, Kasiemobi UchimeAbstractThe diagnosis of oesophageal atresia with or without fistula has traditionally been premised on the clinical finding of excessive salivation, regurgitation of feeds with attendant respiratory compromise in affected neonates. In addition, inability to pass an appropriate sized oesophageal tube into the stomach is confirmatory. OA/TOF is documented to be associated with other congenital abnormalities in up to 50%...

Conclusions: RME promotes a significant gain in the surface area of the palate and an increase in intermolar width. The Hyrax appliance was effective for the treatment of maxillary atresia in growing patients. There was no vertical alteration of the palate . After a 6-month retention period, the maxilla transverse dimension and the surface area of the palate remained stable.RESUMO Objetivo: o objetivo do presente estudo foi estimar a altera ção na área do palato após expansão rápida da maxila (ERM) com o expansor Hyrax em indivíduos em crescimento, utilizando tomografia comp...

Conclusion: Most infants with BA have liver fibrosis at diagnosis and it progresses rapidly. The presence of cirrhosis is correlated with the age at surgery, which suggests the importance of this clinical variable in the evolution of fibrosis.RESUMEN Objetivo: Analizar la evoluci ón de los hallazgos histológicos de pacientes con atresia de vías biliares (AVB), resaltando la progresión de la fibrosis y comparando la biopsia hepática diagnóstica (BHD) con la biopsia hepática quirúrgica (BHQ) mediante la hepatoportoenterostomía de Kasai.

Abstract Reproduction is a major component of an animal's life history strategy. Species with plasticity in their reproductive biology are likely to be successful as an invasive species, as they can adapt their reproductive effort during various phases of a biological invasion. Silver carp (Hypophthalmicthys molitrix), an invasive cyprinid in North America, display wide variation in reproductive strategies across both their native and introduced ranges, though the specifics of silver carp reproduction in the Illinois River have not been established. We assessed reproductive status using histological and endocrinol...

The primary functions of GCs in the individual phases of follicle growth are: Hormone production in response to follicle stimulating hormone (FSH), induction of ovarian follicle atresia through specific molecular markers and production of nexus cellular connections for communication with the oocyte. In recent ...

The emergence of studies of endogenous non-coding RNAs has raised a new aspect for exploration of the regulatory mechanisms involved in follicular atresia. Here, we aimed to illustrate a circRNA involved in the CTGF reg...
