Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...
Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...
Esophageal Strictures-II: Clinical Features and Management01:26

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...
Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

This summary is machine-generated.

Pretreatment swallowing exercises improve swallowing function after chemoradiation for head and neck cancer. These exercises enhance epiglottis inversion and tongue base movement, aiding recovery.

Area of Science:

  • Oncology
  • Otolaryngology
  • Rehabilitation Medicine

Background:

  • Chemoradiation therapy (CRT) for head and neck squamous cell carcinoma often causes debilitating swallowing dysfunction.
  • Previous research indicated pretreatment swallowing exercises improve quality of life post-CRT.
  • This study specifically investigates the impact of these exercises on objective measures of swallowing function.

Purpose of the Study:

  • To evaluate the effect of pretreatment swallowing exercises on posttreatment swallowing function.
  • To assess functional outcomes using videofluoroscopy.
  • To determine the impact on percutaneous endoscopic gastrostomy (PEG) tube use.

Main Methods:

  • Retrospective case-control study of 18 patients with advanced head and neck cancer treated with CRT.
  • Nine patients received pretreatment swallowing exercises; nine received exercises posttreatment.
  • Videofluoroscopy assessed hyoid elevation, epiglottis inversion, tongue base movement, cricopharyngeal opening, and aspiration (Rosenbeck score).

Main Results:

  • Pretreatment exercises significantly improved epiglottis inversion (P = .05).
  • Tongue base movement closer to the posterior pharyngeal wall was observed with pretreatment exercises (P = .025).
  • No significant difference in PEG tube removal rates between groups at 12 months.

Conclusions:

  • Pretreatment swallowing exercises lead to measurable improvements in swallowing function after organ-preserving CRT for head and neck cancer.
  • This supports the development of noninvasive, cost-effective interventions for patients undergoing CRT.
  • Findings provide evidence-based support for incorporating pre-treatment exercises into cancer care protocols.
