Hearing aid and cochlear implant use in children with hearing loss at three years of age: Predictors of use and predictors of changes in use

Objective: To examine usage patterns of hearing aids and cochlear implants in children up to three years of age, how usage changes longitudinally, and factors associated with device usage. Design: Parent report and Parent’s Evaluation of Aural/oral Performance of Children (PEACH) data were obtained at six and twelve months after hearing-aid fitting or cochlear implant switch-on, and again at three years of age. The effect of device use on auditory functional performance was investigated using the PEACH questionnaire. Study sample: Four hundred and thirteen participants from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study were included for analysis. Results: For users of hearing aids, higher usage at three years was associated with higher maternal education, and more severe hearing loss. For users of cochlear implants, higher usage was associated with higher maternal education and the absence of additional disabilities. Higher PEACH scores were associated with higher usage scores. After allowing for the effects of demographic characteristics, device use was not a significant predictor of functional performance. Conclusions: Sixty-two percent of children achieved consistent use (> 75% of waking hours) within the first year of receiving a hearing aid or a cochlear implant, and 71% by three years of age.     

Surgeon Custom-Made Iliac Branch Device to Salvage Hypogastric Artery during Endovascular Aneurysm Repair

Endovascular salvage of the hypogastric artery using iliac branch device (IBD) during endovascular aortic aneurysm repair (EVAR), offers less invasive alternative solution to surgery to prevent pelvic ischemia. We have performed the first Korean surgeon custom-made IBD for this purpose to overcome the limitation of unavailability of the devices in Korea. Four patients with abdominal aortic aneurysm with bilateral common iliac artery aneurysm (CIAA) were treated using custom-made IBDs from October 2013 to December 2013. IBD was created in back table before EVAR operation using TFLE Zenith iliac limb stent graft (Cook Inc.). Three V12 (Atrium, Inc.) one Viabahn (Gore, Inc.) were used for bridging between IBD and target hypogastric artery. With this modification of IBD procedure, exteriorize the guide wire without snare device is possible which offers another benefit in terms of reducing medical costs comparing to commercial IBD. All operations were successful without any device related complications or postoperative endoleaks. During the mean follow up of 3 months, all IBD were patent without clinical complications. Surgeon custom made IBD is feasible and useful to preserve pelvic perfusion especially in the situation of limited commercial IBD availability in many countries. Long-term follow-up is needed to evaluate stent graft patency and IBD-related complications.     

Percutaneous Closure of Atrial Septal Defects in Patients with an Aberrant Retroaortic Coronary Artery: Is It Safe?

Coexistence of an ostium secundum type atrial septal defect and a coronary artery anomaly with an aberrant retroaortic course is a rare congenital anomaly that may potentially complicate percutaneous atrial septal defects (ASD) closure. If the anterosuperior rim of the defect is deficient, the abnormally located coronary artery may be compressed or distorted by the implanted device causing myocardial ischemia, arrhythmias, and eventually sudden cardiac death. Due to the potential occurrence of these fatal cardiac events, diagnosis of an aberrant coronary artery with a retroaortic course must be established before percutaneous ASD closure. In this report, two patients with this rare association are described in whom percutaneous closure of the defect was feasible and uneventful. The importance of a careful periprocedural, noninvasive echocardiographic coronary artery imaging is emphasized, and the rational for percutaneous atrial septal defect closure in this unusual anatomic arrangement is proposed.     

Adverse drug and device reactions in the oral cavity: Surveillance and reporting

BackgroundAccording to the U.S. Centers for Disease Control and Prevention, 48 percent of Americans (roughly 144 million people) used at least one prescribed medication in the preceding month; 11 percent used five or more. The authors describe the U.S. Food and Drug Administration's (FDA's) MedWatch program, the safety surveillance system for drugs and devices in the United States, and the dentist's role with regard to voluntary reporting of adverse effects (AEs). They also identify the most frequent AEs in the oral cavity as reported in the FDA Adverse Event Reporting System (FAERS).MethodsThe authors reviewed the literature regarding MedWatch, and they mined data in the FAERS public database for the 100 most commonly prescribed medications and their associated AEs.ResultsPharyngitis was the most common AE. Cough, dysgeusia and dysphagia also were common.ConclusionThe MedWatch program and its related databases contain useful information about AEs of pharmaceuticals and devices manifested in the oral cavity. Increased participation in the reporting of suspected adverse reactions will improve the national surveillance system and ultimately will protect patients' safety.Practical ImplicationsAs pharmaceutical consumption increases exponentially for a growing segment of the population, and as innovation in dental technology and devices flourishes, dentists have a distinct role in safeguarding patients' well-being. Promptly reporting AEs in the oral cavity improves quality of care and protects patients' well-being.     

Impact of Pump Replacement on Outcome in Advanced Heart Failure Patients With Left Ventricular Assist System

Pump thrombosis is one of the major adverse events associated with the use of a left ventricular assist system (LVAS) in patients with advanced heart failure. We investigated the clinical implication of pump replacement because of thrombus formation. This study included 87 patients who underwent implantation of a Nipro (Toyobo) pulsatile extracorporeal LVAS intended as a bridge to transplantation and were alive more than 3 months after implantation. The pump of this device is translucent, and daily evaluation for signs of thrombus formation was performed. Pump replacement was performed for significant thrombus formation that became visible. Data collection including demographics as well as hematologic values were performed 1 day before (baseline) and 3 months after implantation, and all patients were followed for 2 years or until death. At 3 months after LVAS implantation, 41 patients (47.1%) had undergone pump replacement because of pump thrombus. Baseline body surface area <1.63 m² was a significant predictor of pump replacement (hazard ratio [HR] 2.15, P = 0.04). At 3 months after implantation, there was a significantly higher incidence of stroke (P < 0.05) as well as a significantly greater decrease in body weight (F = 4.92, P = 0.03) in patients who underwent pump replacement as compared to those without. The 2‐year mortality after implantation was 26.4%. Multivariate Cox regression analysis showed that pump replacement within 3 months after implantation was an independent predictor of mortality (HR 2.50, P = 0.03). In conclusion, pump replacement for thrombus formation may have a strong association with worse outcome. Our results reconfirm the clinical importance of device thrombus in the management of LVAS.
