In each of the tunnels, 5 to 11 electrodes were inserted. While the number of active electrodes before revision was 0-5, after revision with the double array, it was increased to 8-12, resulting in improved auditory and speech function.

Revision cochlear implantation with a double array implant using the two tunnel technique can increase the number of active electrodes. This leads to a better outcome in post-meningitis children with completely ossified cochleae and a poor functioning previous device.

Failure to diagnose non-accidental trauma (NAT) leaves the victim at risk of further injury or even death. It is incumbent upon physicians and other health care personnel to identify trauma patterns that have a high likelihood of being caused by NAT. The objective of this study is to discuss the presentation of nasal septal hematoma (NSH) or nasal septal abscess (NSA) as a sign of NAT.

This is a retrospective case series of patients presenting with nasal septal hematoma or abscess between 2010 and 2019. The primary endpoint was the etiology of the injury. Secondary endpoints included demographics, concomitant injuries and treatments rendered.

There were 28 patients who presented with septal hematoma or abscess. The etiologies included 20 (71.4%) due to accidental trauma, four (13.8%) with NAT, one infectious, and three unknown. All four NAT patients were male and infants with an average age of 5.4 months (SD 4.6) significantly (p=0.0069) younger than 10.3 years (SD 5.1) in the accidental trauma group. There was a delayed time to presentation for the NAT patients compared to other etiologies. Two of four NAT patients were initially thought to have a congenital midline nasal dermoid, yet surgical intervention revealed a hematoma. Further NAT evaluation noted concomitant injuries including rib fractures and intracranial injuries in 75% of the NAT patients.

Presentation of a child with NSH/NSA prior to the onset of ambulation or with a delayed time to presentation should prompt suspicion and further workup for NAT.

Epiphora is a common presenting complaint in infants affecting up to 6% of infants in the United States. read more It is most frequently due to congenital anomalies of the nasolacrimal duct system, termed congenital nasolacrimal duct obstruction (CNLDO). Nasolacrimal duct probing is widely accepted as the primary surgical intervention in cases that fail conservative management. Recently, nasal endoscopy has been combined with traditional probing to improve success rates and outcomes. Several studies have been conducted, but the results have been inconclusive overall. The goal of this systematic review is to examine the existing literature on the role of nasal endoscopy during nasolacrimal duct probing and evaluate patient outcomes.

A systematic search was performed in PubMed, MEDLINE, The Cochrane Library, ClinicalTrials.gov, LILAC, and EMBASE to identify peer-reviewed research. Eligible studies were those containing original peer-reviewed research in English addressing nasolacrimal duct probing for congenital nasoal nasolacrimal duct obstruction that does not resolve with conservative treatment often require surgical intervention. Based on this systematic review of the current literature, nasal endoscopy is a useful adjunct for nasolacrimal duct probing.Verbal working memory (VWM) involves visual and auditory verbal information. Neuroimaging studies have shown significant modality effects for VWM in the left posterior parietal cortex (PPC). The left inferior frontal gyrus (IFG) is more sensitive to auditory and phonological information. However, much less is known about the effects of transcranial direct current stimulation (tDCS) over the left PPC and IFG on different sensory modalities of VWM (auditory vs. visual). Therefore, the present study aimed to examine whether tDCS over the left PPC and IFG affects visual and auditory VWM updating performance using a single-blind design. Fifty-one healthy participants were randomly assigned to three tDCS groups (left PPC/left IFG/sham) and were asked to complete both the visual and auditory letter 3-back tasks. Results showed that stimulating the left PPC enhanced the response efficiency of visual, but not auditory, VWM compared with the sham condition. Anodal stimulation to the left IFG improved the response efficiency of both tasks. The present study revealed a modality effect of VWM in the left PPC, while the left IFG had a causal role in VWM updating of different sensory modalities.Chlorine dioxide (ClO2) is a prevalently used disinfectant alternative to chlorine, due to its effectiveness in pathogen inactivation and low yields of organic halogenated disinfection byproducts (DBPs). However, during ClO2 generation, chlorine is inevitably introduced into the obtained ClO2 solution as an "impurity", which could compromise the merits of ClO2 disinfection. In this study, drinking water disinfection with ClO2 containing 0‒25% chlorine impurity (i.e., at Cl2 to ClO2 mass ratios of 0‒25%) was simulated, and the effect of chlorine impurity on the DBP formation and developmental toxicity of the finished water was evaluated. With increasing the chlorine impurity in ClO2, the chlorite level kept decreasing and the chlorate level gradually increased; meanwhile, an unexpected trend from decline to rise was observed for the total organic halogenated DBPs, with the minimum level appearing at 5% chlorine impurity. To unravel the mechanisms for the variations of organic halogenated DBPs with chlorine impurity, a quantitative kinetic model was developed to simulate the formation of chlorinated, brominated, and iodinated DBPs in the ClO2-disinfected drinking water. The modeling results indicated that reactions involving iodide accounted for the decrease of organic halogenated DBPs at a relatively low chlorine impurity level. In accordance with DBP formation, ClO2 with 5% chlorine impurity generated less toxic drinking water than pure ClO2, while significantly higher developmental toxicity was induced until the chlorine impurity reached 25%. For E. coli inactivation, the presence of chlorine impurity enhanced the disinfection efficiency due to a synergistic effect of ClO2 and chlorine. Therefore, disinfection practices with ClO2 containing low chlorine impurity (e.g., less then 10%) might be favored (i.e., there is no need to eliminate low chlorine impurity in the ClO2 solution), while those containing high chlorine impurity should be concerned.
