Reflux of gastric contents into the esophagus, pharynx, and larynx does occur. This phenomenon can produce hoarseness, globus, dysphagia, otalgia and laryngospasm. It may be responsible for the appearance of contact granulomata, esophageal webs, and pachyderma. The key to reflux is the lower esophageal sphincter and the nature of the stomach contents. Multiple factors may be influential including those conditions causing aerophagia. The diagnosis of reflux depends on a high index of suspicion. Physical findings may reveal only subtle changes of arytenoid erythema. Thyrohyoid tenderness is not an infrequent sign. Treatment is usually simple, involving first elimination of those factors which increase intragastric pressure or lower the lower esophageal sphincter pressure. Elevation of the head of the bed and antacids will often prevent further gastric insult to the pharynx and larynx and thus eliminate the patient's discomfort.

Introduction: Computational fluid dynamics (CFD) is gaining momentum as a useful mechanism for analyzing obstructive disorders and surgeries in humans and warrants further development for application in equine surgery. While advancements in procedures continue, much remains unknown about the specific impact that different surgeries have on obstructive airway disorders. The objective of this study was to apply CFD analysis to an equine head inhalation model replicating recurrent laryngeal neuropathy (RLN) and four surgical procedures.

: Opium consumption was recently classified by the International Agency for Research on Cancer (IARC) monograph as carcinogenic to humans based on strong evidence for cancers of the larynx, lung, and urinary bladder, and limited evidence for cancers of the oesophagus, stomach, pancreas, and pharynx. This poses the question of a potential pro-cancer effect of pharmaceutical opioid analgesics. In vitro studies employing a variety of experimental conditions suggest that opioid alkaloids have proliferative or antiproliferative effects.

Head and neck squamous cell carcinoma (HNSCC) originates from the mucosal epithelium of the oral cavity, pharynx, and larynx, and is marked by high rates of recurrence and metastasis. Calcium signaling is associated with the progression of HNSCC and the development of drug resistance. Changes in calcium ion flow can trigger severe pathophysiological processes, including malignant transformation, tumor proliferation, epithelial-mesenchymal transition, and apoptosis evasion.

Article Synopsis
- Speech functions impacted by cleft palate involve complex sound production from various organs, and while traditional evaluations post-surgery are subjective, this study aims to provide objective assessments by measuring muscle contractions during speech.
- A healthy volunteer underwent dynamic MRI while pronouncing Hindi syllables, allowing researchers to create 3D models of the palate and pharynx, then analyze muscle contractions using a finite element model for different sounds.
- Results showed varying contraction levels for the palate and pharyngeal wall with different syllables, with the highest contractions for the syllable /k/ and the potential to use this data to quantify speech issues and evaluate surgical effectiveness in larger populations.
