astroesophageal reflux on 24-hour esophageal pH-metry in mechanically ventilated children with medical diagnoses. The significance of this finding and its impact on ventilator-associated pneumonia and other ventilator-associated events need to be examined in larger studies.
The current study shows high incidence of gastroesophageal reflux on 24-hour esophageal pH-metry in mechanically ventilated children with medical diagnoses. The significance of this finding and its impact on ventilator-associated pneumonia and other ventilator-associated events need to be examined in larger studies.
Left ventricular diastolic dysfunction is associated with difficulty in ventilator weaning and increased mortality in septic adults. We evaluated the association of left ventricular diastolic dysfunction with outcomes in a cohort of children with severe sepsis and septic shock.

Retrospective cohort study.

Single-center noncardiac PICU.

Age greater than 1 month to less than 18 years old with severe sepsis or septic shock from January 2011 to June 2017 with echocardiogram within 48 hours of sepsis onset.

None.

Echocardiograms were retrospectively assessed for mitral inflow E (early) and A (atrial) velocity and e' (early mitral annular motion) septal and lateral velocity. Left ventricular diastolic dysfunction was defined as E/e' greater than 10, E/A less than 0.8, or E/A greater than 1.5. Left ventricular diastolic dysfunction was present in 109 of 204 patients (53%). The data did not demonstrate an association between the presence of left ventricular diastolic dysfunction and the proportion of childefined by both E/e' and E/A and the primary and secondary outcomes. When an alternative definition of left ventricular diastolic dysfunction with E/e' alone was used, there was a significant association with respiratory outcomes.

To investigate whether ultrasound is a helpful and reliable diagnostic tool to survey the status of the magnet previous and after manual repositioning in patients with partially dislocated cochlear implant (CI) magnets and to assess the success rate of a manual repositioning maneuver.

A prospective cohort study.

A tertiary referral medical center.

Patients with a cochlear implant who presented with magnet dislocation after magnetic resonance imaging (MRI) between June 1, 2019 and July 15, 2020.

Manual repositioning of the partially dislocated CI magnet surveyed by pre- and post-interventional ultrasound.

Rate of successfully diagnosed and manually repositioned magnets; complication rate and recurrence rate after initial manual repositioning maneuver.

Nine patients presented with a partial magnet dislocation diagnosed by pre-interventional ultrasound following MRI (n = 9 magnets; three ♀; eight right-sided implants; 65.4 ± 21.7 yr). All magnets were repositioned manually. The magnets were successost-interventional confirmation of the magnet status can be effectively determined by ultrasound. Thus, manual magnet repositioning and ultrasound investigation can be advocated as first-line therapeutic and diagnostic instruments when dealing with partial magnet dislocation.
To determine reasons for premature termination in surgery for congenital aural atresia (CAA).

Retrospective chart review.

High-volume tertiary care center.

Patients undergoing primary surgical repair of CAA whose surgeries were aborted for various indications.

Patients with CAA who underwent elective aural atresia surgery at the University of Virginia from July 2004 to January 2020 were identified from the medical record and an institutional database of patients with CAA. BMH-21 manufacturer Patients undergoing revision surgery or surgery not for hearing correction were excluded. All included candidates were noted to be good surgical candidates for atresia repair based on preoperative Jahrsdoerfer score of 6 or greater. Reasons for terminating surgery prematurely were categorized by anatomical constraints (inability to identify middle ear space, position of the facial nerve, or other anatomic abnormality), stapes fixation, and middle ear and/or mastoid inflammatory disease.

Reasons for premature termination in CAA suo optimize outcomes and prevent complications.
To perform a systematic review of the diagnosis, treatment, and management of patients with otologic manifestations of eosinophilic granulomatosis with polyangiitis.

PubMed, Embase, Cochrane.

A systematic search for relevant published literature in PubMed, Cochrane Library, and EMBASE databases was done. Data was collected on demographics, otologic manifestations, specific diagnostic criteria fulfilled, common clinical, and imaging findings as well as medical and surgical treatments received.

Fifteen articles encompassing 219 patients met inclusion criteria including 8 case reports and 7 case series. The mean age was 52.8 (range of 24-70). The most common otologic presenting symptoms were hearing loss (76%), otitis media with effusion (44%), vertigo (22%), tinnitus (21%), and chronic otitis media (20%). The most common diagnostic criteria observed in these patients were paranasal sinus abnormalities (75%), asthma (66%), and eosinophilia >10% (44%). The most common treatment was systemic steroids (6patients with otologic manifestations. Primary treatment consists of systemic steroids and immunomodulation. M&T, endoscopic sinus surgery, and local steroid administration can be adjunctive measures to alleviate local disease.Level of Evidence Level 1.
The number of cochlear implant (CI) users is ever increasing worldwide, as is the utilization of magnetic resonance imaging (MRI) as a key diagnostic modality for pathology of the brain and surrounding structures. Despite advances in MRI compatibility with CI, metal artefact remains a significant issue that needs to be addressed. We test our hypothesis that the slice encoding for metal artefact correction and view angle tilting (SEMAC-VAT) metal artefact reduction technique improves demonstration of posterior fossa structures on MRI in CI recipients.

A retrospective case review.

A tertiary referral hearing implant and skull base center.

Dedicated MRI of the posterior fossa using T1 spin echo post-gadolinium sequences with and without the application of SEMAC-VAT in CI recipients.

Extent and severity of the artefact and visualization of surrounding anatomic structures with and without the application of SEMAC-VAT, allowing for direct comparison.

Eight CI recipients with nine CI devices were analyzed.
