Oropharyngeal dysphagia (OD) is a swallowing disorder caused by congenital abnormalities and structural damage and disease-associated damage of the oral cavity, pharynx, and upper esophageal sphincter. Patients with OD lack the protective mechanisms necessary for effective swallowing, exhibiting difficulty controlling food in the mouth and initiating a swallow, leading to choking, coughing, and nasal regurgitation. OD is a major risk factor for malnutrition, dehydration, and aspiration pneumonia. The following on OD includes commentaries on the application of simulation of oropharyngeal transient receptor potential vanilloid 1 (TRPV1) and maneuvers like the Shaker exercise to improve the safety and efficacy of swallow in OD patients; the prevalence of esophageal pathologies in OD patients and the need to evaluate the esophagus, esophagogastric junction, and stomach; and strategies for clinical screening to detect OD and aspiration among high-risk patients and to improve oral health care, maintain nutrition and hydration, and prevent aspiration pneumonia.

Aspiration pneumonia (AP) is prevalent in older adults and the hemodialysis (HD) population has been getting older. Therefore, it is speculated that increasing number of HD patients would suffer from AP. However, the clinical aspects of AP in HD patients have not been elucidated. Consecutive HD patients with nosocomial AP hospitalized in our university hospital from April 2007 to December 2008 were recruited. Their clinical characteristics, risk factors for contraction, and the fatality of AP and treatment options were described. Nineteen out of 356 hospitalized HD patients had AP and 8 out of 19 AP patients died, indicating the incidence rate and fatality rate were 5.34% and 42.1%, respectively. Multiple regression analysis revealed that the risk factors for contracting AP included age, body mass index, serum creatinine levels (Cre) and the monthly decline rate of Cre. It also revealed that serum albumin (Alb) and basal total cholesterol levels, the decline rate of Alb and Cre levels, and the duration of AP were independent risk factors for fatality. Survivors were most often treated with tube feeding. Both contraction rate and fatality of nosocomial AP were high among HD patients. Both the malnutrition as well as the decline rate for nutrition and muscle volume indicated by falls in Alb and Cre, respectively, had clinical relevance in AP. Maintaining nutritional state by tube feeding and muscle volume seems to be the mainstay for the prevention and the treatment of AP in HD patients.

Dysphagia is a common problem that has the potential to result in severe complications such as malnutrition and aspiration pneumonia. Based on the complexity of swallowing, there may be many different causes. This article presents a systematic literature review to assess different comorbid disease associations with dysphagia based on age. The causes of dysphagia are different depending on age, affecting between 1.7% and 11.3% of the general population. Dysphagia can be a symptom representing disorders pertinent to any specialty of medicine. This review can be used to aid in the diagnosis of patients presenting with the complaint of dysphagia.

Stroke is regularly accompanied by dysphagia and other factors associated with decreased nutritional intake. Dysphagia with aspiration pneumonia and insufficient nutritional intake lead to worse outcome after stroke.This guideline is the first chapter of the guideline "Clinical Nutrition in Neurology" of the German Society for Clinical Nutrition (DGEM) which itself is one part of a comprehensive guideline about all areas of Clinical Nutrition. The thirty-one recommendations of the guideline are based on a systematic literature search and review, last updated December 31, 2011. All recommendations were discussed and consented at several consensus conferences with the entire DGEM guideline group. The recommendations underline the importance of an early screening and assessment of dysphagia and give advice for an evidence based and comprehensive nutritional management to avoid aspiration, malnutrition and dehydration.

The cricopharyngeal diverticulum or Zenker's diverticulum is the most frequent type of diverticulum of the upper gastrointestinal tract. It occurs mostly in elderly patients. The predominant symptoms are dysphagia and regurgitation which may result in malnutrition and aspiration pneumonia, the latter eventually being life threatening. The underlying cause of Zenker's diverticulum is a dysfunction of the cricopharyngeal muscle and the upper esophageal sphincter, the most common finding being a decreased compliance. The treatment consists in a myotomy of the upper esophageal sphincter and cricopharyngeal muscle combined with a diverticulopexy or diverticulectomy. This procedure is performed via a limited left cervicotomy. Results are excellent to very good in 94% of the patients in our own experience.

Presbyphagia represents the physiological aging of swallowing function. It predisposes to difficulty in swallowing, namely dysphagia, which is of high incidence in the elderly population. The consequences of dysphagia are multiple and always a tragedy for the patient; they consist of aspiration pneumonia, malnutrition, dehydration, social isolation, and death. The diagnosis is difficult and is based on the medical history and clinical examination, associated with diagnostic tests. Its management is multidisciplinary, leaving only little room for medications or surgery.

Dysphagia is a highly prevalent symptom, which may be due to multiple disease processes, both structural and functional, and located at the oropharyngeal or esophageal level. Oropharyngeal dysphagia can cause malnutrition even in 1/3 of patients as a result of alterations in the efficiency of swallowing and cause changes in the security of swallowing (penetration and aspiration) in up to 2/3 of the patients who present it, with high risk of aspiration pneumonia and respiratory infections. In neurological, elderly or institutionalized patients its prevalence may range from 30 to 60%, with different degrees of severity that may become necessary artificial nutrition. It is also related to greater disability, prolonged hospital stays and increased mortality. Therefore, early diagnosis is critical and the establishment of an effective treatment that includes postural exercises, nutritional support and rehabilitation. All this wouldn't be possible without a nutritional team that takes part of the multidisciplinary team patients with dysphagia required. It is the only way to ensure a longterm care to these patients in order to decrease the morbidity and mortality.

Stroke is a public health problem of the first order. In developed countries is one of the leading causes of death, along with cardiovascular disease and cancer. In addition, stroke is the leading cause of permanent disability in adulthood. Many of the patients who survive do so with significant sequelae that limit them in their activities of daily living. Most strokes (80-85%) are due to ischemia, while the rest are hemorrhagic. We have identified many modifiable risk factors, some with an important relationship with dietary factors or comorbidities in wich the diet has a significant impact. The incidence of malnutrition in stroke patients is not well known, but most likely impacts on patient prognosis. Furthermore, the nutritional status of patients admitted for stroke often deteriorates during hospitalization. It is necessary to perform a nutritional assessment of the patient in the early hours of admission, to determine both the nutritional status and the presence of dysphagia. Dysphagia, through alteration of the safety and efficacy of swallowing, is a complication that has an implication for nutritional support, and must be treated to prevent aspiration pneumonia, which is the leading cause of mortality in the stroke patient. Nutritional support should begin in the early hours. In patients with no or mild dysphagia that can be controlled by modifying the texture of the diet, they will start oral diet and oral nutritional supplementation will be used if the patient does not meet their nutritional requirements. There is no evidence to support the use of nutritional supplements routinely. Patients with severe dysphagia, or decreased level of consciousness will require enteral nutrition. Current evidence indicates that early nutrition should be initiated through a nasogastric tube, with any advantages of early feeding gastrostomy. Gastrostomy will be planned when the enteral nutrition support will be expected for long-term (4 weeks). Much evidence points to the importance of glycemic control during hospitalization for stroke. Hyperglycemia at diagnosis and during the first hours of admission impact on patient prognosis. The goal of glycemic control necessary to modify this bad prognosis without adding risk by iatrogenic hypoglycemia is still matter of debate.

Sarcopenic dysphagia is difficulty swallowing due to sarcopenia of generalized skeletal muscles and swallowing muscles. Presbyphagia refers to age-related changes in the swallowing mechanism in the elderly associated with a frailty in swallowing. Presbyphagia is different from dysphagia. The most common cause of dysphagia is stroke. However, sarcopenic dysphagia may be common in the elderly with sarcopenia and dysphagia. Frail elderly with aspiration pneumonia can simultaneously experience activity-, disease-, and nutrition-related sarcopenia of generalized skeletal muscles and swallowing muscles, resulting in the development of sarcopenic dysphagia. Consensus diagnostic criteria for sarcopenic dysphagia were proposed at the 19th Annual Meeting of the Japanese Society of Dysphagia Rehabilitation. The concept of rehabilitation nutrition as a combination of both rehabilitation and nutrition care management is useful for treatment of sarcopenic dysphagia. Therapy for sarcopenic dysphagia includes dysphagia rehabilitation, nutrition improvement and sarcopenia treatment. The core components of dysphagia rehabilitation are oral health care, rehabilitative techniques, and food modification. Nutrition improvement is important, because malnutrition contributes to the etiology of secondary sarcopenia and sarcopenic dysphagia. Assessment of the multi-factorial causes of primary and secondary sarcopenia is important because rehabilitation nutrition for sarcopenia differs depending on its etiology. Treatment of age-related sarcopenia should include resistance training and dietary supplements of amino acids. Therapy for activity-related sarcopenia includes reduced bed rest time and early mobilization and physical activity. Treatment for disease-related sarcopenia requires therapies for advanced organ failure, inflammatory disease, or malignancy, while therapy for nutrition-related sarcopenia involves appropriate nutrition management to increase muscle mass.

Huntington disease (HD) is a degenerative brain disease clinically manifested by the characteristic triad: physical symptoms including involuntary movements and poor coordination, cognitive changes with less ability to organize routine tasks, and some emotional and behavioral disturbances. For patients with HD, feeding is one of the problems they have to face. People with HD often have lower than average body weight and struggle with malnutrition. As a part of therapy, good nutrition is an intervention maintaining health and functional ability for maximally prolonged time. In the early stages of HD, small amounts of blenderized foods given orally are recommended. In more advanced stages, enteral nutrition is essential using gastric, or jejunal tubes for short term. Most severe cases require gastrostomy or gastrojejunostomy. Although enteral feeding is well tolerated by most of the patients, a number of complications may occur, including damage to the nose, pharynx, or esophagus, aspiration pneumonia, sinusitis, metabolic imbalances due to improper nutrient and fluid supply, adverse effects affecting gastrointestinal system, and refeeding syndrome.
