BACKGROUND: We report the case of a giant intrathyroidal parathyroid adenoma weighing 59 g in a young woman presenting acutely with severe hypercalcemia requiring correction and adequate preoperative management prior to surgery. Parathyroid adenomas account for 85 % of cases of primary hyperparathyroidism. Those weighing more than 3.5g are classified as giant parathyroid adenomas. There are only 25 cases of parathyroid adenomas weighing over 30g reported in the literature. With the wide availability of biochemical screening tests in Western countries, mildly elevated calcium levels are often discovered incidentally...

INTRODUCTION: Although dyspnea with exercise in the pediatric population can be multifactorial, the diagnosis of paradoxical vocal fold motion disorder (PVFMD) in this group is not well characterized. The objective of this study is to review the multiple causes of dyspnea with exercise in children, including the prevalence of PVFMD within this study population. METHODS: A retrospective review was conducted of patients seen at a tertiary pediatric hospital for exercise-induced dyspnea suspected to be related to PVFMD between January 2007 and July 2015...

Many children who are admitted to pediatric hospitals with the chief complaint of apparent life-threatening event (ALTE) are, in fact, well appearing by the time the inpatient medical team evaluates the patient. This presents a diagnostic and therapeutic challenge. We describe a case of a six-month-old full-term female presenting with an ALTE and found to have a double aortic arch, a congenital anomaly that usually presents with a more progressive onset of symptoms such as chronic cough, positional stridor, and feeding difficulties...

Bilateral vocal fold immobility (BVFI) is commonly caused by injury to the recurrent laryngeal nerve (RLN) and leads to stridor and dyspnea of varying onsets. A retrospective study was done at the Department of Otorhinolaryngology of Universiti Kebangsaan Malaysia Medical Centre on laser microsurgical posterior cordectomy for BVFI. The objectives were to identify the average duration of onset of stridor from the time of insult and to evaluate the outcome of laser posterior cordectomy as a surgical option. From 1997 to 2007, a total of 31 patients with BVFI were referred for surgery...

BACKGROUND: Accumulation of α-synuclein in multiple system atrophy (MSA) affects medullary autonomic and respiratory control areas, including the rostral ventrolateral medulla and raphe nuclei. Relative neuronal vulnerability and its relationship to α-synuclein accumulation in these areas are unknown. The aim of this study was to determine the extent of loss of adrenergic neurons in the rostral ventrolateral medulla and serotonergic neurons in the ventrolateral medulla and raphe nuclei and its relationship with α-synuclein accumulation...

BACKGROUND: In developing countries with limited access to ENT services, performing emergency cricothyroidotomy in patients with upper airway obstruction may be a life-saving last resort. An established Danish-Zimbabwean collaboration of otorhinolaryngologists enrolled Zimbabwean doctors into a video-guided simulation training programme on emergency cricothyroidotomy. This paper presents the positive effect of this training, illustrated by two case reports. CASE REPORTS: A 56-year-old female presented with upper airway obstruction due to a rapidly progressing infectious swelling of the head and neck progressing to cardiac arrest...

OBJECTIVE: To evaluate the predictive value of stridor and its latency of onset and to investigate the role of stridor treatment in a cohort of patients with multiple system atrophy (MSA) referred to a tertiary center. METHODS: We retrospectively identified patients diagnosed with MSA referred to our department beginning in 1991 and evaluated at least yearly during the disease course. Stridor was defined as present when confirmed by a whole night video-polysomnography and as early if presenting within 3 years of disease onset...

BACKGROUND: Diffuse idiopathic skeletal hyperostosis (DISH) is an idiopathic spinal disease common in the elderly and characterized by flowing ossification and osteophyte formation along the spinal column. Cervical hyperostosis is capable of producing dysphagia, stridor, and airway obstruction; however, there are no extant reports of true paralysis of bilateral vocal folds in patients fulfilling the criteria for DISH. METHODS AND RESULTS: We report a case of a 61-year-old man presenting with dysphagia and dyspnea...

Hydromorphone, unlike other opioids associated with histamine release, has never been reported to cause angioedema. We report a rare case of hydromorphone-induced angioedema in a 34-year-old woman with history of deep venous thrombosis and pulmonary embolism who presented with leg swelling and pain after trauma. Hydromorphone was administered with subsequent rapid development of stridor and edematous changes of the tongue, uvula, and surrounding mucosa. The difficult airway response team was activated, and the airway was secured by emergent awake fiberoptic intubation in the operating room...

BACKGROUND: Urgent airway management is one of the most important responsibilities of otolaryngologists, often requiring a multidisciplinary approach. Urgent surgical airway intervention is indicated when an acute airway obstruction occurs or there are intubation difficulties. In these situations, surgical tracheostomy becomes extremely important. METHODS: We retrospectively studied the patients who underwent surgical tracheostomy from 2011 to 2014 by an otolaryngologist team at the operating theater of the emergency department of a tertiary hospital...

PURPOSE: To determine if implementing a protocol maintaining an air leak when using cuffed endotracheal tubes (ETT) throughout the course of mechanical ventilation (MV) in children would decrease the rate of postextubation stridor (PES). METHODS: All children requiring MV through a cuffed ETT were included, except those with (1) upper airway anomaly, (2) died while on MV, (3) received tracheostomy before extubation, and (4) transferred before extubation. We implemented a protocol limiting the volume of air instilled into the cuff, allowing an air leak by 25 cm H2O pressure or by peak inspiratory pressure, whichever was higher...

A case of a 55-year-old woman with iatrogenic vocal cord trauma and sleep-related symptoms is reported. In particular, this case highlights sleep-disordered breathing as a delayed complication after iatrogenic vocal cord trauma. The patient developed acute stridor from a contralateral vocal cord hematoma following vocal fold injection for right vocal cord paralysis. Acute respiratory symptoms resolved with oxygen, steroids, and nebulized therapy, but nocturnal symptoms persisted and polysomnography revealed sleep-related hypoventilation and mild obstructive sleep apnea...

BACKGROUND: No guidelines exist for the evaluation of patients after near hanging. Most patients receive a comprehensive workup, regardless of examination. We hypothesize that patients with a normal neurologic examination, without major signs or symptoms suggestive of injury, require no additional workup. METHODS: We reviewed medical charts of adult trauma patients who presented to a Level I trauma center between 1995 and 2013 after an isolated near-hanging episode...
