ABSTRACT
INTRODUCTION: This study tests the utilization of Bluetooth noise-canceling headphones in improving the quality of eye exams in patients with hearing loss. This prospective study was approved on ethical standards by the University of Texas Medical Branch (UTMB) Institutional Review Board (Approval No. 22-0079) and registered with the National Institutes of Health (NCT05420038). METHODS: UTMB patients above 55 years of age were screened for hearing loss using soundcheck audiometry. Twenty-nine subjects answered pre-recorded ophthalmic exam questions that solicited precise responses. As controls, subjects were randomly administered half of the questions via headphones and half via a smartphone at normal speech volume (60 decibels). Points were awarded for responses demonstrating comprehension, and a post-exam survey was collected. RESULTS: Collectively, the mean score was 1.79 with headphones versus 0.96 with control on the Amsler grid segment and 1.90 with headphones versus 0.97 with control on education questions (p=0.001). Between red zone and yellow zone hearing loss patients, the more severe red zone group answered significantly better in both Amsler (1.78 versus 0.50; p=0.0003) and education questions (1.88 versus 0.44; p<0.0001) with headphones. The yellow zone group answered better with headphones overall but failed to reach significance. Post-exam survey indicated that 28 of 29 patients (97%) preferred the headphones during ophthalmic exams. CONCLUSION: Patients with hearing loss demonstrated better comprehension with Bluetooth headphones. These low-cost devices show great promise at improving effective, compassionate communication between providers and hearing loss patients.
ABSTRACT
Secondary hyperparathyroidism is a prevalent complication of end-stage renal disease (ESRD), arising from chronic renal insufficiency leading to disturbed calcium metabolism. This disruption triggers hypersecretion of the parathyroid gland, characterizing the condition. Osteitis fibrosa cystica (OFC), a rare complication of untreated secondary hyperparathyroidism, results in benign resorptive bone lesions and the formation of cystic cavities within bones. Our case report describes a 46-year-old incarcerated Hispanic male with a 17-year history of end-stage renal disease and secondary hyperparathyroidism. The patient initially presented with a traumatic right elbow injury. Further diagnostic evaluation revealed an 8 cm destructive process involving the distal humerus, initially suspected as malignancy but confirmed as OFC through bone biopsy. Management involved orthopedic surgery performing an open reduction and internal fixation (ORIF) of the affected limb, with subsequent consideration for inpatient parathyroidectomy. Imaging studies, including magnetic resonance imaging (MRI) and computed tomography (CT) scans, elucidated a 6 × 5.5 cm soft tissue mass, further confirmed as a brown tumor. The case underscores the complexities of diagnosing OFC, often misinterpreted in radiologic studies, and highlights the multidisciplinary approach involving orthopedics, otolaryngology, and nephrology in managing this intricate scenario. The objective is to explore clinical manifestations and treatment challenges of OFC and secondary hyperparathyroidism triggered by trauma in end-stage renal disease, emphasizing the need for continued awareness and precise diagnostic strategies in resource-rich areas.
