    Objectives The aim of this study was to analyze the incidence of inner ear anomalies in patients with unilateral congenital aural atresia (CAA) combined with microtia. Methods We retrospectively reviewed 61 patients with unilateral CAA combined with microtia who underwent high-resolution temporal bone computed tomography (TBCT) and hearing examination. Inner ear anomalies were analyzed using TBCT and evaluated according to the Jahrsdoerfer grading system, Marx classification, and extent of inferior displacement of the mastoid tegmen. Results Inner ear anomalies were observed in 14 patients (23.0%). Lateral semicircular canal (LSCC) dysplasia was the most common inner ear anomaly, with an incidence of 16.4%. The incidence was significantly higher on the pathologic side than on the unaffected side (P=0.002). All vascular anomalies were observed in the high-riding jugular bulb, with an incidence of 24.6%. The incidence was significantly higher on the pathologic side than on the unaffected side (P<0.001). LSCC dysplasia was significantly more common in patients with a lower Jahrsdoerfer score (odds ratio, 0.66; P=0.004). Conclusion The incidence of inner ear anomalies was relatively high in patients with unilateral CAA combined with microtia; LSCC dysplasia was the most common anomaly and the probability of coexistence was higher in patients with a lower Jahrsdoerfer score

    ObjectivesTo determine the frequency and characteristics of complications of peripherally administered hypertonic saline (HTS) through assessment of infiltration and extravasation.DesignRetrospective cross-sectional study.SettingFreestanding tertiary care pediatric hospital.PatientsChildren who received HTS through a peripheral IV catheter (PIVC).InterventionsNone.Measurements and main resultsWe conducted a single-center retrospective review from January 2012 to 2019. A total of 526 patients with 1,020 unique administrations of HTS through a PIVC met inclusion criteria. The primary endpoint was PIVC failure due to infiltration or extravasation. The indication for the administration of HTS infusion was collected. Catheter data was captured, including the setting of catheter placement, anatomical location on the patient, gauge size, length of time from catheter insertion to HTS infusion, in situ duration of catheter lifespan, and removal rationale. The administration data for HTS was reviewed and included volume of administration, bolus versus continuous infusion, infusion rate, infusion duration, and vesicant medications administered through the PIVC. There were 843 bolus infusions of HTS and 172 continuous infusions. Of the bolus administrations, there were eight infiltrations (0.9%). The continuous infusion group had 13 infiltrations (7.6%). There were no extravasations in either group, and no patients required medical therapy or intervention by the wound care or plastic surgery teams. There was no significant morbidity attributed to HTS administration in either group.ConclusionsHTS administered through a PIVC infrequently infiltrates in critically ill pediatric patients. The infiltration rate was low when HTS is administered as a bolus but higher when given as a continuous infusion. However, no patient suffered an extravasation injury or long-term morbidity from any infiltration

    Factors impacting adherence to an exercise-based physical therapy program for individuals with low back pain

    Background/objectiveExercise-based rehabilitation is a conservative management approach for individuals with low back pain. However, adherence rates for conservative management are often low and the reasons for this are not well described. The objective of this study was to evaluate predictors of adherence and patient-reported reasons for non-adherence after ceasing a supervised exercise-based rehabilitation program in individuals with low back pain.DesignRetrospective observational study.MethodsData was retrospectively analyzed from 5 rehabilitation clinics utilizing a standardized exercise-based rehabilitation program. Baseline demographics, diagnosis and symptom specific features, visit number, and discontinuation profiles were quantified for 2,243 patients who underwent the program.ResultsForty-three percent (43%) of participants were adherent to the program, with the majority (31.7%) discontinuing treatment prior to completion due to logistic and accessibility issues. Another 13.2% discontinued prior to the prescribed duration due to clinically significant improvements in pain and/or disability without formal discharge evaluation, whereas 8.3% did not continue due to lack of improvement. Finally, 6.0% were discharged for related and unrelated medical reasons including surgery. Individuals diagnosed with disc pathology were most likely to be adherent to the program.LimitationsThis study was a retrospective chart review with missing data for some variables. Future studies with a prospective design would increase quality of evidence.ConclusionsThe majority of individuals prescribed an in-clinic exercise-based rehabilitation program are non-adherent. Patient diagnosis was the most important predictor of adherence. For those who were not adherent, important barriers include personal issues, insufficient insurance authorization and lack of geographic accessibility

    An integrated ion-selective optode sensor cartridge for directly detecting electrolyte ions in blood plasma without pretreatment to adjust pH

    We present a new integrated optode sensor cartridge that directly detects potassium, sodium, and chloride ions in blood plasma without pretreatment to adjust pH. Each optode sensor mainly consists of two separate layers, the optode and a dried buffer, which work by introducing plasma without blood cells filtered by a membrane filter. The optode layer uses a neutral ion-selective optode that is composed of an ionophore, a pH indicator dye (chromoionophore), and ionic additives incorporated in a plasticized polyvinyl chloride membrane. The dried buffer layer, which dissolves on contact with plasma, is applied to the optode layer, resulting in the constant pH of the plasma within the optode membrane. We determined the pHs of each dried buffer (potassium, sodium, and chloride) layer to be 7.0, 6.0, and 4.5, respectively, based on the pKa of their corresponding chromoionophores and effective buffer ranges. Consequently, the sensor responses varied as a function of the potassium, sodium, and chloride ion concentrations. To validate the accuracy of the ion-selective optode sensors, we investigated the correlations of potassium, sodium, and chloride ion concentrations with a commercial system (cobas® 8000) and observed comparable agreement between the two systems with correlation coefficients of 0.976, 0.955, and 0.966, respectively. © 2018 Elsevier B.V.1
