OBJECTIVES To determine the relationship between body mass index and tracheal airway size in children. METHODS Retrospective case series. CT or MRI images of the neck of 171 pediatric patients obtained from 2000 to 2010 at a tertiary pediatric hospital were analyzed. Age, gender, height, weight, BMI and CDC weight classification for each patient were compared with axial CT measurements (AP diameter and width) and calculated cross-sectional airway area. Linear regression models were performed to identify factors predictive of airway size. RESULTS Age ranged from 2 to 20 years. Weight was the most significant predictor of tracheal AP diameter (P = 0.029), with height also approaching statistical significance (P = 0.051). Tracheal width was best predicted by height (P = 0.09). Weight was the only statistically significant predictor of cross-sectional tracheal area (P = 0.002). Body mass index was not a statistically significant predictor of airway size in any dimension; however, there was an obvious trend towards decreasing tracheal width and cross-sectional area in patients with BMI of 25 or greater. CONCLUSION In pediatric patients, estimation of endotracheal or tracheostomy tube size should take into account height, weight and BMI in addition to the patient's age. Patients with elevated BMI may have smaller tracheal sizes in various dimensions than normal or low-weight patients. INTRODUCTION As healthcare moves away from volume-based to value-based delivery models, evidence based clinical pathways detail essential steps in patient care to reduce the costs and utilization of health care resources. Ideal pathways lead towards standardized, patient-centered care through an algorithm that is evidence-based, interventions with criteria-based progression, and measurable endpoints or quality indicators. Using these standards, a clinical pathway for managing tympanostomy tube otorrhea beginning with phone triage was developed in accordance with AAO-HNSF Guidelines. https://www.selleckchem.com/products/ABT-263.html METHODS A retrospective case series of all consecutive patients calling the otolaryngology nurse's line at a tertiary pediatric hospital 3/2018-11/2018 regarding otorrhea was performed. Nurses completed a standardized and evidence-based form based on parent responses regarding purulence, tympanostomy tubes/perforation, fever>102°, ear redness, bacterial rhinosinusitis, sore throat, and immunodeficiency, which was sent to the advanc visits in 82.9% of patients with a 75.6% treatment cure. Sensorineural hearing loss is a heterogeneous disease caused by mutations in many genes. However, in the presence of enlarged vestibular aqueduct, it is frequently associated with mutations in the solute carrier family 26 member 4 (SLC26A4), a gene causative of a syndromic form (Pendred) as well as a non-syndromic form of hearing loss (DFNB4). We describe a clinical case presenting bilateral sensorineural hearing loss and enlarged vestibular aqueduct in which a novel homozygous SLC26A4 mutation was identified. Despite a late diagnosis of hearing loss, a peculiar rehabilitation therapy strategy was identified that provided excellent results. INTRODUCTION Down Syndrome (DS) is a Tier 1 risk factor for hearing loss. Guidelines exist to ensure close monitoring of children with DS for hearing loss. It is important to consider the timing of testing in order to obtain meaningful audiologic data in this high-risk population. The purpose of this study is to present hearing outcomes for children with DS during the first 8 years of life and to assess these outcomes in the context of current screening guidelines. METHODS Retrospective review of audiometric outcomes was conducted for children with DS age 8 or younger who presented to a multidisciplinary DS clinic between January 2014 to June 2017. Age at the time of testing, as well as test success rate and hearing loss type and severity were noted. RESULTS 131 patients were included in the study, 52% of which were male. 36% of the patients failed their newborn hearing screening and only 9% of those subjects had normal hearing on subsequent testing. Most hearing loss identified was mild and conductive in nature. Inconclusive results were most likely to be obtained at 6-10 months of age. CONCLUSION Hearing loss is common among children with DS. To optimize the quality of testing and avoid the need for sedation in followup testing, routine follow-up hearing screening should be performed either before 6 months of age or after 10 months of age. Proper functioning of the auditory nerve is of critical importance for auditory rehabilitation by cochlear implants. Here we used the Cldn14-/- mouse to study in detail the effects of Claudin 14 loss on auditory synapses and the auditory nerve. Mutations in the tight junction protein Claudin 14 cause autosomal recessive non-syndromic hearing loss (DFNB29) in humans and mice, due to extensive degeneration of outer and inner hair cells. Here we show that massive inner hair cell loss in Cldn14-/- mice starts after the third postnatal week. Immunohistochemical analysis, using presynaptic Ribeye and postsynaptic GluR2 or PSD 95 as markers, revealed the degeneration of full ribbon synapses in inner hair cells from apical cochlear regions already at postnatal day 12 (P12). At P20, significant reduction in number of ribbon synapses has been observed for all cochlear regions and the loss of synaptic ribbons becomes even more prominent in residual inner hair cells from middle and apical cochlear regions at P45, which bdegeneration process in otherwise morphologically inconspicuously inner hair cells. In addition to the regression of peripheral nerve processes, reduced levels of VGLUT-1 in the VCN of Cldn14-/- mice suggests that Claudin 14 loss does not only cause hair cell loss but also affects peripheral and central connectivity of the auditory nerve. With the phase out of perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), the composition profiles of poly- and perfluoroalkyl substance (PFAS) in our living environment are unclear. In this study, 25 PFASs were analyzed in indoor dust samples collected from urban, industrial, and e-waste dismantling areas in China. PFOS alternatives, including 62 chlorinated polyfluorinated ether sulfonate (62 Cl-PFESA) (median 5.52 ng/g) and 82 chlorinated polyfluorinated ether sulfonate (82 Cl-PFESA) (1.81 ng/g), were frequently detected. By contrast, PFOA alternatives, such as hexafluoropropylene oxide dimer acid (HPFO-DA, Gen-X) and ammonium 4,8-dioxa-3H-perfluorononanoate (ADONA), were not found in any of the dust samples. As expected, all legacy PFASs were widely observed in indoor dust, and 4 PFAS precursors were also detected. Dust concentrations of 62 Cl-PFESA were strongly correlated (p  less then  0.05) with those of 82 Cl-PFESA regardless of sampling sites. 62 Cl-PFESA was also significantly associated with that of PFOS in industrial and e-waste (p  less then  0.
