A Chronic Glottic Foreign Body Diagnosed by Radiograph after 9 Months of Symptoms.

A six-year-old girl presented to an emergency room after describing choking on a rubber band. She was in no distress and was discharged. Over the course of the next 9 months, she had numerous outpatient and emergency room visits due to intermittent stridor, difficulty breathing, and hoarseness. Eventually, dedicated airway films revealed a laryngeal foreign body. During rigid bronchoscopy, a two-centimeter rubber band was discovered in the larynx. It extended from the supraglottis, through the glottis, and into the subglottis. It was successfully removed. The patient was asymptomatic 24 hours later. This case highlights the appropriate evaluation and management of a child with stridor.

Fluvastatin protects cochleae from damage by high-level noise.

Exposure to noise and ototoxic drugs are responsible for much of the debilitating hearing loss experienced by about 350 million people worldwide. Beyond hearing aids and cochlear implants, there have been no other FDA approved drug interventions established in the clinic that would either protect or reverse the effects of hearing loss. Using Auditory Brainstem Responses (ABR) in a guinea pig model, we demonstrate that fluvastatin, an inhibitor of HMG-CoA reductase, the rate-limiting enzyme of the mevalonate pathway, protects against loss of cochlear function initiated by high intensity noise. A novel synchrotron radiation based X-ray tomographic method that imaged soft tissues at micrometer resolution in unsectioned cochleae, allowed an efficient, qualitative evaluation of the three-dimensional internal structure of the intact organ. For quantitative measures, plastic embedded cochleae were sectioned followed by hair cell counting. Protection in noise-exposed cochleae is associated with retention of inner and outer hair cells. This study demonstrates the potential of HMG-CoA reductase inhibitors, already vetted in human medicine for other purposes, to protect against noise induced hearing loss.

Management of acute complicated mastoiditis at an urban, tertiary care pediatric hospital.

OBJECTIVES/HYPOTHESIS: To describe the presentation and management of acute complicated mastoiditis in children. STUDY DESIGN: Retrospective case series. METHODS: An analysis of pediatric patients with acute complicated mastoiditis treated at an urban, tertiary care children's hospital from 2007 to 2014 was performed. RESULTS: Forty-eight patients presented with a total of 67 complications of acute mastoiditis. Mean age at presentation was 4.8 years (range = 0.1-15.3 years). The most common complications were subperiosteal abscess (n = 22, 45.8%), epidural abscess (n = 16, 33.3%), and sigmoid sinus thrombosis (n = 14, 29.2%). The most common pathogens isolated included Streptococcus pneumoniae (n = 14, 29.2%) and group A streptococcus (n = 10, 20.8%). Multidrug resistance was not associated with complication type. Surgical management included myringotomy ± tympanostomy tube placement in 46 (95.8%) patients (the only surgery in 10), drainage of subperiosteal abscess without mastoidectomy in 18 (37.5%) patients, and mastoidectomy in 21 (43.8%) total patients. Patients presenting with intracranial complications were the most likely to undergo a mastoidectomy. Anticoagulation was used in the management of nine of 14 (64.3%) patients presenting with sigmoid sinus thrombosis. Neurosurgical interventions (n = 7, 14.6% patients) were primarily performed to manage increased intracranial pressure. CONCLUSIONS: Subperiosteal abscess was the most common complication of acute mastoiditis, and when occurring as the sole complication was successfully managed with antibiotics and surgical intervention that did not include mastoidectomy. Epidural abscess and sigmoid sinus thrombosis were more prevalent than reported in prior series and were managed more aggressively. These patients were more likely to need neurosurgical interventions. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:2321-2327, 2017.

Mammographic findings after intraoperative radiotherapy of the breast.

Intraoperative Radiotherapy (IORT) is a form of accelerated partial breast radiation that has been shown to be equivalent to conventional whole breast external beam radiotherapy (EBRT) in terms of local cancer control. However, questions have been raised about the potential of f IORT to produce breast parenchymal changes that could interfere with mammographic surveillance of cancer recurrence. The purpose of this study was to identify, quantify, and compare the mammographic findings of patients who received IORT and EBRT in a prospective, randomized controlled clinical trial of women with early stage invasive breast cancer undergoing breast conserving therapy between July 2005 and December 2009. Treatment groups were compared with regard to the 1, 2 and 4-year incidence of 6 post-operative mammographic findings: architectural distortion, skin thickening, skin retraction, calcifications, fat necrosis, and mass density. Blinded review of 90 sets of mammograms of 15 IORT and 16 EBRT patients demonstrated a higher incidence of fat necrosis among IORT recipients at years 1, 2, and 4. However, none of the subjects were judged to have suspicious mammogram findings and fat necrosis did not interfere with mammographic interpretation.
