BACKGROUND: The perception of sour taste in humans is incompletely understood at the receptor cell level. We report here on two patients with an acquired sour ageusia. Each patient was unresponsive to sour stimuli, but both showed normal responses to bitter, sweet, and salty stimuli.
METHODS AND FINDINGS: Lingual fungiform papillae, containing taste cells, were obtained by biopsy from the two patients, and from three sour-normal individuals, and analyzed by RT-PCR. The following transcripts were undetectable in the patients, even after 50 cycles of amplification, but readily detectable in the sour-normal subjects: acid sensing ion channels (ASICs) 1a, 1beta, 2a, …

OBJECTIVES: Airway endoscopy is a difficult skill to master. A unique practicum was designed to help otolaryngology residents develop endoscopy skills. The learning modalities included lectures, an animal laboratory, high-fidelity manikins, virtual bronchoscopy simulation, and standardized patients. This study compares the relative subjective value of these learning modalities for skill development and realism. METHODS: Participants used a Likert scale (1=disagree to 5=agree) and open responses to anonymously rate the efficacy of 5 learning modalities for teaching airway management, endoscopy skills, and clinical leadership and for providing a realistic experience. RESULTS: The results in 2007 were uniformly positive, with mean scores …

We present a case report that describes the pathology, presentation, and management complexities of an unusual, destructive fibrosclerotic lesion of the laryngotracheal complex. An otherwise healthy 21-year-old man presented with a 1-year history of progressive shortness of breath and stridor. The initial examination revealed a 3-cm, grade III subglottic stenosis. Nodular fibrosis of the strap muscles, laryngotracheal cartilages, and trachea was evident. Biopsies revealed dense peritracheal desmoplastic reaction with focal erosion of cartilage. However, features diagnostic for relapsing polychondritis, desmoid tumor, or orbital pseudotumor were absent. The disease progressed to involve severe stenosis and thickening of the trachea and main …

The thyroid gland is a relatively uncommon site for a secondary malignancy; even less common is a case of malignant melanoma metastatic to the thyroid. We describe the case of a 68-year-old man who presented with a neck mass in the posterior triangle. Fine-needle aspiration biopsy (FNAB) identified the mass as a malignant melanoma. The patient had had no known primary skin melanoma. He underwent a left modified radical neck dissection, and the mass was discovered to be a positive lymph node. Postoperatively, he declined to undergo radio- and chemotherapy. Eighteen months later, he returned with a diffusely enlarged thyroid. …
