The paper describes the changes in the cricopharyngeal muscle in seven cases of dysphagia resulting from obstruction at this level which was relieved by myotomy. Histological features included degeneration and regeneration in the muscle fibres with interstitial fibrosis which was severe in some of the cases. It is considered that this restrictive fibrosis is the cause of the dysphagia and that it is secondary to muscle fibre damage, the cause of which is at present obscure. Minor degrees of muscle damage and regeneration were seen rarely in controls and fibrosis was never present. There was no evidence of underlying vascular or neurological disease in six cases; the seventh had a previous history of scleroderma but this was not thought to be the cause of the cricopharyngeal lesion. The age incidence ranged from 1 to 5 years at the onset of dysphagia; in six of the seven it was 50 years or more.

Gastroesophageal reflux (GER) has been recognized with increasing frequency as the source of a wide variety of symptoms in infants and children. During the past 8 years at the UCLA Hospital, 74 patients under 18 years of age have been identified as having sufficiently severe symptomatic reflux to warrant gastroesophageal fundoplication. Although repeated emesis was the most common primary symptom, failure to thrive was a major symptom in 20 patients, repeated pneumonia in 18, asthma in five, and dysphagia owing to stricture in 12. Nine patients with previously repaired esophageal atresia had severe reflux. Serious neurologic disorders were present in 14 children. The diagnosis of reflux in the majority of symptomatic children was established by combining the findings of an abnormal esophagogram, Tuttle test, esophageal manometry, and esophagoscopy with biopsy. Six infants experienced repeated symptomatic GER although results of all diagnostic studies were normal. Each of the patients had undergone an unsuccessful trial of medical management before the decision to operate was made. Transabdominal Nissen fundoplication with gastrostomy was performed on each of the 74 children (28 under 1 year of age). Each of the strictures was successfully managed by postoperative dilatations. No death and no major complications occurred, but six patients experienced transient dysphagia and four had delayed gastric emptying. Every patient has been relieved of clinical reflux, and the pulmonary status in each, including the asthmatic children, has been markedly improved. On the basis of this favorable experience with 74 patients, we believe that an aggressive surgical approach should be taken in the management of symptomatic GER in infants and children who fail to respond to an adequate trial of medical management.

The existence of specific, age-related changes in gastrointestinal motility with clinical significance is controversial. Beside the more infrequent primary motility disorders, secondary motility disturbances associated with collagen vascular diseases, endocrinopathies, and neuromuscular diseases are prominent in the older and often multimorbid patients. Especially in geriatric patients, motility associated symptoms are undesired side-effects of drug therapy. The pathophysiology, clinical syndromes, and therapeutic principles of motility disorders in the elderly are discussed. The major symptoms of esophageal dysfunction are dysphagia, chest pain, heartburn, and regurgitation. Oropharyngeal dysphagia, mostly caused by cerebrovascular accidents and other neurologic disorders, leads to disturbances in food intake, and is often complicated by broncho-pulmonary infections arising from recurrent aspiration of food or saliva. Gastrointestinal reflux disease and spastic motility disorders of the esophagus are regarded as possible causes of angina-like chest pain after exclusion of cardiac diseases. Motility disturbances of the stomach and small bowel are often related to systemic disease (i.e., diabetes mellitus, chronic intestinal pseudo-obstruction) of drug side-effects. Mental and physical decline, reduced fluid intake, and constipating drugs are the most relevant factors for idiopathic constipation in the elderly. Fecal incontinence means a great psychological strain for older patients and leads to social isolation.

Certain swallowing disorders characteristically may follow head and neck surgeries and neurologic disorders. Aspiration is one of the possible symptoms of dysphagia. Since aspiration can be life-threatening, prosthodontists should help to identify patients who aspirate. This article describes the normal swallowing physiology, the pathophysiology of swallowing disorders, and the prosthetic role in the treatment of patients experiencing head and neck surgical operations and neurologic disorders that may cause aspiration.

Nineteen cases are described, including 12 cases from three different families and 7 nonfamilial cases, in which multisystem neurological disease was associated with acanthocytosis in peripheral blood and normal plasma lipoproteins. Mild acanthocytosis can easily be overlooked, and scanning electron microscopy may be helpful. Some neurologically asymptomatic relatives with significant acanthocytosis were identified during family screening, including some who were clinically affected. The mean age of onset was 32 (range 8-62) yrs and the clinical course was usually progressive but there was marked phenotypic variation. Cognitive impairment, psychiatric features and organic personality change occurred in over half the cases, and more than one-third had seizures. Orofaciolingual involuntary movements and pseudobulbar disturbance commonly caused dysphagia and dysarthria that was sometimes severe, but biting of the lips or tongue was rarely seen. Chorea was seen in almost all symptomatic cases but dystonia, tics, involuntary vocalizations and akinetic-rigid features also occurred. Two cases had no movement disorder at all. Computerized tomography often demonstrated cerebral atrophy. Caudate atrophy was seen less commonly, and nonspecific focal and symmetric signal abnormalities from the caudate or lentiform nuclei were seen by magnetic resonance imaging in 3 out of 4 cases. Depression or absence of tendon reflexes was noted in 13 cases and neurophysiological abnormalities often indicated an axonal neuropathy. Sural nerve biopsies from 3 cases showed evidence of a chronic axonal neuropathy with prominent regenerative activity, predominantly affecting the large diameter myelinated fibres. Serum creatine kinase activity was increased in 11 cases but without clinical evidence of a myopathy. Postmortem neuropathological examination in 1 case revealed extensive neuronal loss and gliosis affecting the corpus striatum, pallidum, and the substantia nigra, especially the pars reticulata. The cerebral cortex appeared spared and the spinal cord showed no evidence of anterior horn cell loss. Two examples of the McLeod phenotype, an X-linked abnormality of expression of Kell blood group antigens, were identified in a single family and included 1 female. The genetics of neuroacanthocytosis are unclear and probably heterogeneous, but the available pedigree data and the association with the McLeod phenotype suggest that there may be a locus for this disorder on the short arm of the X chromosome.

Swallowing is a brief but intricate process. When this process is interrupted, as in patients with neurologic disorders, problems such as aspiration and risk of malnutrition can occur. The authors of this article discuss an individualized approach to evaluation and management of neurogenic oropharyngeal dysphagia. Three cases illustrate the diversity of causes, signs and symptoms, and clinical course.

Tube feedings are utilized in elderly patients with acute and chronic problems. Inadequate oral intake with malnutrition, comatose state, neurologic disorders with severe dysphagia, extensive burns, massive gastrointestinal resection, and oropharyngeal and upper gastrointestinal malignancies are the commonly encountered conditions requiring tube alimentation. Dysphagia with frequent aspiration is the most common indication for use of tube feedings in the elderly. Nasogastric tube is preferred for short-term feeding, while gastrostomy or jejunostomy is indicated for long-term or permanent nutritional support. Nutritional assessment should be done initially and on a regular basis. Specific formulas are available to calculate height, weight, and caloric needs of bedbound elderly patients. Various enteral feeding formulas are available for a specific clinical condition and are preferably administered by continuous drip using a pump. Parenteral nutrition is also indicated for certain situations in which enteral feeding cannot meet the patient's nutritional requirement, and in particular situations where enteral feeding is contraindicated and not feasible. Optimal patient care is dependent on adequate nutritional support.

Dysphagia is a major problem in patients with neurologic disorders. Aspiration pneumonia and impaired nutritional status are consequences of dysphagia that result in high morbidity and mortality rates. Assessment and treatment of the dysphagic patient by a multidisciplinary team have been advocated but to date the effects of such an approach have not been demonstrated quantitatively. This prospective study was conducted to determine if a dysphagia program would improve patients' caloric intake and body weight, decrease the instances of aspiration pneumonia, or improve patients' feeding ability. Patients were referred from a 26 bed neurology/neurosurgery unit. A time series design was utilized. The control group consisted of 15 patients (mean age = 46.1 years), managed according to the existing ward routine. Subsequently, nursing staff attended a dysphagia training program. Following this, the treated group of 16 patients, (mean age = 49.3 years) was assessed by the dysphagia team, using bedside and videofluoroscopic examinations to determine the specific swallowing disorder. An individualized treatment program was designed for each patient. The groups were compared on the basis of deviation from their baseline weight, deviation from ideal energy intake, and the incidence of aspiration pneumonia. Statistical analysis revealed that the groups were comparable in age, number of days on the study, and Glasgow Coma Scale score; and that a significant weight gain and increase in caloric intake occurred in the treated group. No incidence of aspiration pneumonia was reported in either group. We speculate that this may have been influenced by the meticulousness of the care delivered in an acute unit as well as greater attention to prevention given in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

A retrospective study investigated the incidence and types of communication problems in 115 patients referred for swallowing difficulties. Each patient had a bedside swallowing evaluation completed as well as a screening of communication abilities. A formal speech-language evaluation was done when warranted and possible. Of the 115 patients, 93 had suspected swallowing problems based on the bedside evaluation done by the speech-language pathologist. Videofluoroscopy was performed on 85 of these patients. A significant positive correlation was found between communication impairments and both suspected and videofluoroscopically confirmed dysphagia. Cognitive problems were the most frequent communication impairment with dysarthria being second. Neurological diseases were the most common medical diagnoses in patients with swallowing difficulties. The case is presented for the speech-language pathologist to be the primary diagnostician and manager of both communication and oral-pharyngeal swallowing disorders whether they co-occur or not.

We studied digestive manifestations occurring during follow-up of 19 cases of myotonic dystrophy. GI symptoms occurred in 10 patients (53%), mainly dysphagia (n = 7). In patients undergoing investigations (n = 7), their digestive troubles were probably or definitively related to the neurological disease in 6 cases. Upper GI endoscopy was normal in 5 dysphagic patients. The oesophageal manometry was abnormal in 3 of 4 patients. Complications developed in 3 cases (16%). One patient presented two episodes of spontaneous pneumoperitoneum. A second one developed a chronic colonic pseudo-obstruction with megacolon treated by subtotal colectomy. Manometric studies revealed oesophageal aperistalsis, low amplitude of gastro-jejunal contractions but persistence of migrating motor complexes and a normal recto-anal reflex. A third patient developed an acute pseudo-obstruction with ischemic colitis. In conclusion, myotonic dystrophy frequently disturbs digestive tract motility and may cause complications such as intestinal pseudo-obstruction.
