Abstract
289 esophageal manometries performed for 7 years to patients with dysphagia and normal upper gastro-intestinal endoscopy were analyzed, excluding patients with systemic sclerosis and preoperative manometries for gastroesophageal reflux disease. Esophageal motor disorders are frequent in patients with non obstructive dysphagia. Esophageal manometry is important to perform in these patients. Specific treatment is required in patients with achalasia. Systemic sclerosis and gastroesophageal reflux disease should be suspected in patients with esophageal hypomotility.

Abstract
Achalasia is a disorder of the oesophagus characterised by increased lower oesophageal sphincter (LOS) tone, lack of LOS relaxation with swallowing and aperistalsis of the body of the oesophagus. The aetiology and pathogenesis of idiopathic achalasia are still unclear, although a viral cause, genetic influences (associations with HLA loci) and autoimmune processes have been postulated. Degeneration and significant loss of nerve fibres, associated with an inflammatory infiltrate of the myenteric plexus in idiopathic achalasia, provide evidence of an immune mediated destruction of the myenteric plexus, possibly through apoptotic process. This concept is reinforced by the concomitant appearance of achalasia and Guillain-Barré syndrome (GBS) and/or Parkinson's disease, where inappropriate initiation of apoptosis has been proposed to underlie the neuronal attrition. In the same respect, Helicobacter pylori (H. pylori) infection has been associated with gastric autoimmunity, and patients infected with H. pylori have been shown to possess autoantibodies that cross-react with antigens expressed on the gastric mucosa. Furthermore, H. pylori is thought to be associated with the development of autoimmune sequelae observed in peripheral neuropathies and GBS, where autoantibodies to specific neural targets have been found to impair native neural function by inducing nerve tissue damage, possibly by apoptosis. Taken together, we assume that H. pylori infection might be a pathogenetic factor of achalasia through induction of autoimmunity and apoptosis. Whether eradication of H. pylori infection may indirectly offer benefit to the pathophysiology of idiopathic achalasia by ameliorating the apoptotic loss of ganglion cells and their axons in the oesophageal wall remains to be elucidated.

Abstract
The unusual combination of Hirschsprung's disease and Achalasia in one case treated by standard procedures led to the discussion about RET germ-line mutations and consequently to the speculation about higher risk for multiple endocrine neoplasia syndrome type 2-related tumors. Although a mutation could be excluded by sequence analysis in this case, the correlation of these specific diseases affords additive investigations to make sure that no further prophylactic procedures were necessary.

Abstract
Chronic neutropenia syndromes include distinct hereditary disorders with varying degrees of neutropenia. Among the more common inherited disorders associated with symptomatic neutropenia are cyclic neutropenia, severe congenital neutropenia (Kostmann disease), and Schwachman-Diamond syndrome. The authors describe a 17-year-old girl with triple A syndrome who developed a progressive decrease in the granulocyte count, finally resulting in long-standing neutropenia. Its probable pathogenesis may be related to dysfunction of ALADIN (the protein known to be mutated in triple A syndrome), resulting in abnormal nucleocytoplasmic transport of essential proteins, in myeloid precursor cells. Chronic neutropenia should therefore be considered among the clinical manifestations of triple A syndrome.

Abstract
OBJECTIVE To report a case of a 9-year-old female presented with esophageal achalasia and approached with surgery. The authors discuss the treatment and make a literature review on the topic. DESCRIPTION Childhood esophageal achalasia is an unusual disease, often with unknown etiology. The main symptoms are esophageal vomits, dysphagia and weight loss. The diagnosis can be made by esophagogram and endoscopy, but the main examination is the esophageal manometry. Even though the surgical approach is a well-established therapy, some alternative treatments have been used, such as the endoscopy balloon dilatation and the use of botulinum toxin. COMMENTS Esophageal achalasia is a rare disease in childhood, with unknown etiology. The presentation may be confused with gastroeshophageal reflux, sometimes causing a diagnosis delay. The surgical approach, as well as an antireflux procedure, is the treatment of choice.

Abstract
Achalasia has been described following fundoplication and is attributed to vagal nerve damage during surgery. Similarly, other traumatic events to the distal esophagus may be linked to the development of achalasia. Operative and nonoperative trauma as a possible factor in the development of achalasia was studied. A retrospective analysis of patients with achalasia (n = 64) at our institution was performed. Collected data included age, gender, symptoms, and history of operative and nonoperative traumatic events. Comparisons were made to a group of patients with similar symptoms but normal esophageal manometry (n = 73). Achalasia was diagnosed by manometry in 125 patients over a 6-year period. All patients with complete medical records (n = 64) were studied. A history of operative or nonoperative trauma to the upper gastrointestinal tract prior to the development of symptomatic achalasia was present in 16 of 64 (25%). Significantly fewer patients (9.5%) with symptoms of dysphagia, but normal manometry and upper endoscopy, had precedent trauma to the upper gastrointestinal tract (P < 0.05). All cases of nonoperative trauma occurred in motor vehicle accidents. Cases of operative trauma included coronary artery bypass surgery (n = 4), bariatric surgery (n = 2), fundoplication (n = 3), heart/lung transplantation (n = 1), and others (n = 5). Patients with proven achalasia and a history of trauma were more likely to have chest pain (RR, 4.5; P = 0.012) but less likely to have regurgitation (RR, 0.51; P = 0.01) or nausea/vomiting (RR, 0.0; P = 0.27) than those without a history of antecedent trauma. In this series, significantly more patients with achalasia had a history of preceding trauma than did patients with similar symptoms and normal esophageal manometry. Following trauma, patients may be at increased risk for developing achalasia, possibly from neuropathic dysfunction due to vagal nerve damage. Patients with posttraumatic achalasia may have symptoms which differ from those of other achalasia patients.

Abstract
A 14-year-old boy presented with regurgitation, malnutrition, and chronic lung insufficiency with a history of successful repair of esophageal atresia and tracheoesophageal fistula in the newborn period. Barium swallow and manometry results showed achalasia. Hellar operation with antireflux procedure resulted in complete symptomatic relief. Histology and immunohistochemistry including PGP9.5, MAP5, cKit, and nNOS of myotomy specimen showed intact innervation. Although esophageal dysmotility after esophageal atresia repair usually is caused by gastroesophageal reflux and incoordination of peristalsis, the possibility of achalasia should also be considered, because a casual relationship between esophageal atresia and achalasia may exist.

Abstract
We review the treatment of esophageal achalasia by means of pneumatic dilatation (PD), analyzing its results and comparing them with those of the literature. We conclude that our personal experience is similar to that of the literature: PD and surgery produce similar results (67-95%), morbidity (2-9.5%), and mortality (0.7-1%); and PD is cheaper than surgery. According to these conclusions, we believe that the decision of the appropriate treatment should be based on a combination of the choice of the properly informed patient and the operator's experience. However, we also conclude that surgery is mandatory in selected cases, such as achalasia associated with hiatus hernia, esophageal diverticula and neoplasia, history of previous PD failure (since in our experience the results after a second PD are very poor), postoperative relapse, and patients with grade IV mega-esophagus according to Resano-Malenchini's classification.

Abstract
BACKGROUND Achalasia is considered to be a primary motor disorder of the oesophagus. However, there is increasing evidence to suggest extra-oesophageal involvement in this disease. Vagal disturbances at different levels and extra-oesophageal dysmotility have been reported in several studies. The aim of this study was to examine cardiovascular reflexes in patients with achalasia further to evaluate the involvement of the autonomic nervous system outside the oesophagus in this entity. METHODS Five patients (age range 38-58 years, median 45 years) diagnosed with achalasia were assessed for the autonomic nerve function by the heart rate reaction to deep breathing (E/I ratio) and to tilt (acceleration and brake index). The blood pressure reaction to tilt was also assessed. The results were compared with a control group comprising 56 healthy individuals (age range 16-59 years, median 40 years). RESULTS Patients with achalasia had a significantly decreased E/I ratio compared with controls (absolute values 1.13 (0.23) (median value (interquartile range)) versus 1.38 (0.14): P=0.0309, age corrected values -1.39 (1.49) versus -0.25 (1.20): P=0.0457). This reflects impairment of the vagus nerve. In contrast, sympathetic nerves were not affected, as the acceleration index and brake index and postural blood pressure reaction were not disturbed in patients. CONCLUSION Patients with achalasia have autonomic nerve dysfunction in the vagal nerve outside the oesophagus.

Abstract
Achalasia is a condition of unknown etiology. It represents a motor disorder of the esophagus characterized by absent or incomplete relaxation of the lower esophageal sphincter upon swallowing and by non-propulsive swallow-induced contraction waves or amotility of the esophageal body. Dysphagia and regurgitation of ingesta are the most frequent symptoms. Medical treatment, i.e. by calcium-channel blockers and nitric oxide donors, may be tried in patients with mild dysphagia or in elderly patients but rarely yields adequate symptom relief. Mechanical dilatation of the achalasic sphincter may be performed as an initial treatment option. Intrasphincteric injections of botulinum toxin seemed to be a promising alternative, but it has become obvious that, in most cases, repeated applications of the toxin are required to maintain patients symptom-free. Myotomy of the achalasic sphincter with or without fundoplication to prevent gastroesophageal reflux, is employed mainly in patients in whom dilatations have failed, but since the introduction of minimally invasive surgery, myotomy has become the primary treatment at many centers. This article aims to provide an overview of the development of the conservative and surgical treatment of achalasia.

Abstract
Chagasic megaesophagus is a chronic disease that courses with progressive dysphagia, regurgitation and protein-calorie malnutrition. Advanced or recurrent megaesophagus can be treated with Serra Dória's operation (cardioplasty, partial gastrectomy and gastrojejunal Roux-en-Y anastomosis). A nutritional evaluation was performed on 27 patients (mean age 58 +/- 10 years) with chagasic megaesophagus at admission and after postoperative day 90. The nutritional state was assessed through global subjective nutritional evaluation (GSNE), anthropometry and laboratorial exams, besides the analysis of alimentary intake. In the preoperative period, GSNE pointed to malnutrition in 2/3 patients, while the anthropometric and laboratorial evaluation revealed that over 60% of the patients had protein-calorie malnutrition of the marasmic type. The preoperative nutritional state as evaluated by GSNE did not correlate with complications or postoperative mortality. The postoperative evaluation showed an increase in the intake of proteins, recovery in the body mass index and a reduction in the hemoglobin levels of the peripheral blood.

Abstract
BACKGROUND Although idiopathic achalasia and achalasia caused by Chagas' disease have the same clinical manifestations and treatment, both with destruction of the esophageal myenteric plexus, it is possible that there are differences in the alterations of esophageal motility between the two diseases, caused by different grades of impairment of the excitatory and inhibitory esophageal neurons. AIMS We performed a review of papers with results about the pathophysiology and esophageal motility alterations in idiopathic achalasia and Chagas' disease. DATE SOURCES We reviewed papers which included data about the characteristics of idiopathic achalasia and Chagas' disease. DATA SYNTHESIS Impairment of inhibitory esophageal neurons was shown in the two diseases. The results of the studies of the effects of atropine, edrophonium and botulin toxin suggested that the excitatory innervation is more intensely impaired in Chagas' disease than in idiopathic achalasia, explaining the increase in the lower esophageal sphincter pressure found in achalasia. The patients with Chagas' disease have more circulating muscarinic cholinergic receptor M2 autoantibodies than patient with idiopathic achalasia. The duration of the contractions in the esophageal body is longer in idiophatic achalasia than in Chagas' disease. CONCLUSIONS The papers that studied Chagas' disease and idiopathic achalasia, mainly those which studied both diseases with the same methods, suggested that there are different grades of esophageal involvement by the two diseases, mainly the most important involvement of excitatory innervation in Chagas' disease than in idiopathic achalasia.

Abstract
Foram analisados os achados radiológicos e manométricos de 43 pacientes portadores de megaesôfago chagásico com sorologia positiva para doença de Chagas. Encontrou-se uma redução significante dos valores da pressão máxima do corpo do esôfago com relação ao estádio da esofagopatia: grau I/II - 42,9mmHg; grau III - 23,6mmHg; grau IV - 15,6mmHg. Observou-se que cinco (35,7%) pacientes classificados como grau III, do ponto de vista radiológico, apresentaram valores da pressão máxima do corpo do esôfago inferiores a 20mmHg, sendo considerados portadores de megaesôfago avançado, devendo ser tratados por esofagectomia subtotal com esofagogastroplastia ao invés de cardiomiotomia com válvula anti-refluxo. Constatou-se que o estudo manométrico é útil em pacientes portadores de megaesôfago grau III para a escolha do melhor procedimento cirúrgico.

Abstract
According to the WHO, 16-18 million people in Central and South America are infected by Trypanosoma cruzi. Chagasic achalasia affects between 7.1% and 10.6% of the population. The aim of this study was to evaluate the effects of Botox injections in the clinical response and esophageal function of patients with dysphagia due to chagasic achalasia. In total, 24 symptomatic patients with chagasic achalasia were randomly chosen to receive Botulinum Toxin (BT) or saline injected by endoscopy in the lower esophageal sphincter (LES). Patients were monitored with a clinical score of dysphagia and an objective assessment (esophagograms, scintillography, manometry, and nutritional assessment) for a period of 6 months. Clinical improvement of dysphagia was statistically significant (P < 0.001) in patients receiving BT when compared with the placebo. There was no significant difference in the placebo group regarding clinical score, LES basal pressure and esophageal emptying time. Esophageal emptying time in the toxin group was significantly lower than in the placebo (P=0.04) after 90 days. There were non-significant increases in esophageal emptying of 25.36% and 17.39%, respectively, at 90 and 180 days, in the BT group (P=0.266). Gender, age, and baseline LES pressure did not influence the response to BT. Our data strongly suggests that intrasphincteric injection of BT in LES is clinically effective in the treatment of chagasic achalasia.

Abstract
An 8 1/2-year-old neutered male Beagle was diagnosed with acquired myasthenia gravis associated with a non-invasive thymic carcinoma. The thymic mass was surgically excised and the dog was treated with pyridostigmine, prednisolone and azathioprine. Serial acetylcholine receptor antibody titres were increased initially but slowly declined to normal values over a period of 24 weeks. Improved exercise tolerance was seen following therapy, however, oesophageal dysfunction persisted. The dog was euthanased 26 weeks after initial presentation due to a complicating illness. A necropsy showed no regrowth or metastasis of the thymic carcinoma.

Abstract
Secondary achalasia or pseudoachalasia is mostly caused by gastric or oesophageal carcinoma. Here we report a case of pseudoachalasia caused by a pancreatic tumour invading the cardiac region. A 66-year-old man with a 2-month history of dysphagia and weight loss showed no abnormalities on upper gastrointestinal endoscopy and computed tomography scan, but had no swallow-induced relaxation on oesophageal manometry. Based on the patient's history and oesophageal manometry findings, further investigation was performed to exclude pseudoachalasia. Endoscopic ultrasonography showed abnormalities in the cardiac region, but large endoscopic biopsies showed no malignancy. A laparotomy was performed, which revealed a large, irresectable tumour originating from the pancreatic corpus region and expanding into the gastric cardia region. This case illustrates that a pancreatic tumour invading the cardiac region may present as pseudoachalasia.

Abstract
We report the case of a 50-year-old male, a known case of achalasia cardia for 15 years, who after being successfully treated earlier by pneumatic dilatation, presented with recurrent dysphagia due to vascular tethering of the megaoesophagus by the azygos arch simulating a malignant oesophageal stricture. The patient underwent oesophagectomy because of our inability to rule out the possibility of a malignancy developing in the mid-portion of the long-standing megaoesophagus. We wish to highlight the existence of this new clinical entity and the diagnostic as well as therapeutic dilemmas posed by it.

Abstract
The study investigated the esophageal motility of 98 patients with Chagas' disease and 40 asymptomatic volunteers, with the objective of comparing patients with vigorous achalasia (distal amplitude contractions >/= 37 mmHg) and patients with classical achalasia (amplitude < 37 mmHg). The Chagas' disease patients had normal esophageal radiologic transit (n=60) or esophageal slow transit and retention without dilation (n=38). The manometric method with continuous perfusion was used to study esophageal motility. Comparison of classical and vigorous achalasia showed no difference in duration of contractions, lower and upper esophageal sphincter pressure, proportion of patients with dysphagia, or the number of multipeaked contractions. The number of failed contractions was higher in patients with classic achalasia than in patients with vigorous achalasia. We conclude that the distinction between classical and vigorous achalasia does not seem to be important for the classification of Chagas' disease.
