Dysphagia
|July 13, 2020
Summary
Dysphagia, difficulty swallowing, is common in lateral medullary syndrome (LMS). Understanding its causes, outcomes, and treatments is crucial for patient care and recovery.
Area of Science:
- Neurology
- Gastroenterology
Background:
- Dysphagia is a frequent and serious complication of lateral medullary syndrome (LMS).
- It significantly impacts patient outcomes, increasing risks of aspiration pneumonia, malnutrition, and mortality.
- The underlying pathophysiology of dysphagia in LMS requires further elucidation.
Purpose of the Study:
- To review the pathophysiology, prognosis, and treatment of dysphagia in lateral medullary syndrome.
- To highlight the interconnectedness of these aspects in managing LMS-related swallowing difficulties.
Main Methods:
- Literature review of existing studies on dysphagia in lateral medullary syndrome.
- Analysis of pathophysiological mechanisms, prognostic factors, and therapeutic interventions.
Main Results:
- While many LMS patients have a good prognosis for dysphagia, some experience severe, prolonged swallowing issues.
- Medullary central pattern generators are implicated in swallowing coordination.
- Various treatments, including non-invasive (rTMS, tDCS) and invasive (Botox, dilatation, myotomy) methods, are applied.
Conclusions:
- Effective management of dysphagia in LMS necessitates understanding its pathophysiology and prognosis.
- Further research with larger cohorts is needed to optimize specific therapeutic modalities and improve patient outcomes.

306
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...

593
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
592
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
333
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:30Esophageal Strictures-I: Introduction
455
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:26Enteral Nutrition I: Orogastric and Nasogastric Feeding
919
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...
