MR imaging findings of a rare pediatric parotid tumor: Mammary analogue secretory carcinoma.

We present magnetic resonance imaging findings of an 11-year-old girl with a mammary analogue secretory carcinoma (MASC) of the parotid gland. MASC is a recently described tumor of the salivary glands that is genetically and histologically similar to secretory breast carcinoma. To date, a few cases have been reported in the pediatric population, with limited information of its imaging characteristics.

Multidisciplinary management of oculo-auriculo-vertebral spectrum.

Purpose Of Review: Oculo-auriculo-vertebral spectrum (OAVS) is a complex disorder that is represented by wide variations in phenotypic presentation. Recent publications and systematic reviews of the available literature are presented here.

Recent Findings: Treatment strategies vary among craniofacial centers across the country.

What are we putting in our ears? A consumer product analysis of aural foreign bodies.

Objectives/hypothesis: Rapid identification of foreign bodies may be crucial in deciding the appropriate course of action; and knowledge of consumer products that most commonly become aural foreign bodies (AFB) may potentially guide patient education strategies. Our objectives were to estimate the nationwide incidence of emergency department (ED) visits for consumer products presenting as AFBs and describe products encountered, demographic trends, general outcomes, and other reported aspects of injury.

Methods: The authors searched the National Electronic Injury Surveillance System for AFB ED visits from 2008 to 2012.

Cleft lip - a comprehensive review.

Orofacial clefts comprise a range of congenital deformities and are the most common head and neck congenital malformation. Clefting has significant psychological and socio- economic effects on patient quality of life and require a multidisciplinary team approach for management. The complex interplay between genetic and environmental factors play a significant role in the incidence and cause of clefting.

Participation of Kv1 channels in control of membrane excitability and burst generation in mesencephalic V neurons.

The function and biophysical properties of low threshold Kv1 current in control of membrane resonance, subthreshold oscillations, and bursting in mesencephalic V neurons (Mes V) were examined in rat brain stem slices (P8-P12) using whole cell current and voltage patch-clamp methods. alpha-dendrotoxin application, a toxin with high specificity for Kv1.1, 1.
