IMPAIRED QUALITY OF LIFE IN CHAGAS ACALASIA PATIENTS AND ASSOCIATED CLINICAL FACTORS.

BACKGROUND: No study has focused on Health-Related Quality of Life (HRQoL) for Chagas Achalasia patients. Objective: To compare HRQoL between Chagas Achalasia patients and the general population; and to correlate HRQoL with clinical factors that can affect it. METHODS: Sixty Chagas Achalasia patients and 50 controls were evaluated. All patients underwent esophageal manometry for the diagnosis of achalasia and esophagogram to determine the grade of megaesophagus. Three questionnaires were used: 1) clinical: the following data were collected: demographic, medical history, body mass index, occurrence of six esophageal symptoms (Esophageal Symptom Score: number of symptoms reported by patients), duration of dysphagia; 2) socio-economic-cultural status evaluation: patients and controls answered seven questions about their socio-economic-cultural conditions; 3) HRQoL: the validated Brazilian-Portuguese version of the Short-form Health Survey (SF-36) questionnaire (license QM020039) was used. It measures health in eight domains: 3a) four physical: physical functioning, role limitations relating to physical health, bodily pain, and general health perception; 3b) four mental: vitality, social functioning, role limitations relating to emotional health, and mental health. These domains can be summarized into Physical and Mental Summary scores. We analyzed correlations between SF-36 Physical/Mental Summary Component scores and the following clinical factors: Esophageal Symptom Score, duration of dysphagia, body mass index, grades of megaesophagus (defined by the esophagogram) and presence/absence of megacolon (defined by opaque enema). RESULTS: Patients and controls had similar age, gender, medical history, and socio-economic-cultural lifestyles (P>0.05). All patients had dysphagia and megaesophagus. SF-36 scores were significantly lower in Chagas Achalasia patients than controls for all eight domains (physicals: P<0.002; mentals: P<0.0027). The Physical and Mental Summary Component scores were also lower in Chagas Achalasia patients than controls (P<0.0062). For patients, the Physical Summary score was negatively correlated to Esophageal Symptom Score (P=0.0011) and positively correlated to body mass index (P=0.02). No other correlations were found. CONCLUSION: Chagas Achalasia patients have an impaired HRQoL in all physical and mental domains. Patients reporting more symptoms had worse physical domains. Patients with higher body mass index had better physical domains.

[Catheter balloon dilation combined with acupuncture for cricopharyngeal achalasia after brain stem infarction: a randomized controlled trial].

OBJECTIVE: To screen the optimal acupuncture regimen for cricopharyngeal achalasia (CPA) after brain stem infarction and compare the therapeutic effect between the combined therapy of catheter balloon dilation and acupuncture and the simple application of catheter balloon dilation. METHODS: The patients suffering from neuropathic dysphagia in CPA after brain stem infarction were selected as the subjects. After confirmed in the diagnosis with video fluoroscopic swallowing study (VFSS), they were randomized into 6 groups, 15 cases in each one, named group A (routine treatment), group B (catheter balloon dilation), group C1 (treated with acupuncture in local area), group C2 (treated with acupuncture based on zangfu differentiation), group C3 (treated with acupuncture at the local area and the acupoints based on zangfu differentiation) and group D (catheter balloon dilation combined with the optimal acupuncture). Two phases were included in the study. In the first phase of study, the therapeutic effect was compared among the three acupuncture groups, named C1, C2 and C3 group, so as to screen the optimal acupuncture regimen. In the group C1, the main acupoints included Fengchi (GB 20), Wangu (GB 12), Yifeng (TE 17) and three-tongue points (Extra). In the group C2, the main acupoints were Neiguan (PC 6), Tongli (HT 5), Zusanli (ST 36) and Sanyinjiao (SP 6) as well as the supplementary acupoints in accordance with the syndrome differentiation. In the group C1 and group C2, after deqi, the electroacupuncture was used, with continuous dense wave, 5 to 8 Hz in frequency. The needles were retained for 30 min. Acupuncture was given once a day, 5 treatments a week. Before treatment, in 6 weeks of treatment or after removal of gastric tube, the rehabilitation was evaluated. In the group C3, the acupoints, manipulation and treating course were same as the group C1 and group C2. In the 2nd phase of study, theresults of rehabilitation treatment were compared among the group A, group B and group D. The treatment was given once a day, 5 times a week. Before treatment, after gastric tube removal or in 6 weeks of treatment, the evaluation was conducted. The feeding-swallowing function grade and VFSS were adopted in the evaluation among the above 6 groups. RESULTS: ① In the VFSS comparison at 1st phase of study after treatment, the food transporting ability at oral dysphagia, the results in the group C3 and group C1 were better obviously than the group C2 (both P<0.05). For the improvement in aspiration, the result in the group C3 was better obviously than the group C2 (P<0.05). In comparison of the three acupuncture groups with the group A, the difference was not significant statisticallys in the extubation rate among the four groups (P>0.05). The severity of dysphagia in the group C3 was milder than the group C2 and group A (both P<0.05). ② In the VFSS comparison at the 2nd phase of study, for the food transporting ability, the results in the group D and the group B were obviously better than the group A (both P<0.05). Regarding the function at the pharyngeal dysphagia and aspiration, the results in the group D were better than the group B and group A, those in the group B were better than the group A (all P<0.05). The difference in the extubation rate among the group A, group B and group D after treatment was significant statistically (P<0.01), of which, the extubation rate in the group D was the highest and the rate in the group A was the lowest. The dysphagia degree in the group D was milder than the group B and group A and that in the group B was milder than the group A (all P<0.05). CONCLUSION: In the study of the different acupuncture methods, the acupuncture at the local acupoints and the acupoints selected based on zangfu differentiation is the optimal acupuncture regimen for cricopharyngeal achalasia after brain stem infarction. The catheter balloon dilation combined with acupuncture present the synergistc effect on cricopharyngeal achalasia after brain stem infarction, obviously relieve dysphagia and reduce aspiration.

Dysphagia Post Subcortical and Supratentorial Stroke.

BACKGROUND: Studies have recognized that the damage in the subcortical and supratentorial regions may affect voluntary and involuntary aspects of the swallowing function. The current study attempted to explore the dysphagia characteristics in patients with subcortical and supratentorial stroke. METHODS: Twelve post first or second subcortical and supratentorial stroke patients were included in the study. The location of the stroke was ascertained by computed tomography and magnetic resonance imaging. The characteristics of swallowing disorder were assessed by video fluoroscopic swallowing assessment/fiberoptic endoscopic evaluation of swallowing. The following main parameters were analyzed: oral transit time, pharyngeal delay time, presence of cricopharyngeal muscle achalasia (CMA), distance of laryngeal elevation, the amounts of vallecular residue and pyriform sinus residue (PSR), and the extent of pharyngeal contraction. RESULTS: Eighty-three percent of the 12 patients were found suffering from pharyngeal dysphagia, with 50% having 50%-100% PSRs, 50% having pharyngeal delay, and 41.6% cases demonstrating CMA. Simple regression analysis showed PSRs were most strongly associated with CMA. Pharyngeal delay in the study can be caused by infarcts of basal ganglia/thalamus, infarcts of sensory tract, infarcts of swallowing motor pathways in the centrum semiovale, or a combination of the three. CONCLUSION: Subcortical and supratentorial stroke may result in pharyngeal dysphagia such as PSR and pharyngeal delay. PSR was mainly caused by CMA.

[Rehabilitation of the patients presenting with oesophageal achalasia following balloon cardiodilation].

The present study involved a total of 25 patients presenting with oesophageal achalasia who had undergone balloon cardiodilation. The complex of rehabilitative measures concluded the application of an ultrahigh-frequency electromagnetic fields (decimeter wave (DMW) therapy) to the collar region and general iodine bromide baths. The treatment resulted in the elimination of dysphagia syndrome during consumption of solid food in 80% of the patients. Simultaneously, the oesophagogastroscopic study revealed the improvement of the state of oesophageal mucosa. Moreover, the thyrotropin level was normalized. The positive effect of such rehabilitative treatment persisted during 6-8 months.

[Megaesophagus]. / Mégaoesophage.

Although it was first described a long time ago, the pathophysiology of megaesophagus, a primary esophageal motor disorder due to an abnormality of the esophageal sphincter reflex ("achalasia"), remains poorly understood. Our paper shows that it may also be missed clinically for a long time, sometimes for psychological reasons.

[Esophageal achalasia of chagasic origin: report of a case diagnosed in the pre-symptomatic stage]. / Achalasia esofágica de origen chagásico: a propósito de un caso diagnosticado en etapa pre-sintomática.

A 42 year old male that presented with functional gastrointestinal symptoms is presented. X ray examination showed an esophageal diameter of 3 cm, measured 6 cm above the gastroesophageal junction. This finding, according to previous experiences of the authors, is highly suggestive of Chagasic esophageal involvement. The patient resided in a highly endemic area for Chagas disease; hemagglutination, latex agglutination and ELISA serological tests for Chagas disease were positive. The manometric study of the esophagus confirmed the diagnosis showing an elevated lower esophageal sphincter pressure and hypomotility and poor amplitude contractions of the esophageal body. Barium enema and EKG were normal. Upper gastrointestinal endoscopy disclosed an erosive gastritis that could explain the patients' symptomatology. The antiquity of Chagas infection was estimated in 18 years. This case represents an example of early diagnosis of esophageal involvement in the course of Chagas disease.

Incidência de megacólon sintomático em portadores de megaesôfago chagásico / Incidence of symptomatic megacolon in patients with chagasic megaesophagus

Os autores analisam a incidência de megacólon associado a megaesôfago num período de sete anos. Entre 192 portadores de megaesôfago foram investigados, através de enema opaco, apenas os doentes que apresentavam sintomas sugerindo comprometimento intestinal. Foram diagnosticados 15 casos (7,8%) desta associaçäo. Entre o grupo com megaesôfago e o grupo com a associaçäo megaesôfago e megacólon, näo foram encontradas diferenças significativas quanto ao sexo e idade dos pacientes e grau de megaesôfago. Os sintomas esofágicos, no momento do diagnóstico, precederam os intestinais em 93,3% dos doentes. O tratamento foi variado, mas recentemente, os autores obtiveram bons resultados com o tratamento simultâneo, através de cardiomiotomia de Heller com técnica de Lortat-Jacob modificada e hemicolectomia esquerda

[Incidence of symptomatic megacolon in patients with chagasic megaesophagus]. / Incidência de megacólon sintomático em portadores de megaesôfago chagásico.

The authors analyze the incidence of megacolon associated to megaesophagus during a 7 year period. Of the 192 patients with megaesophagus only 15 who presented associated intestinal symptoms were further investigated through barium enema. No statistically significant differences were found between the group with megaesophagus and the group presenting association of megaesophagus and megacolon as to sex and age of the individuals and severity of megaesophagus. The esophageal symptoms preceded the intestinal symptoms in 93.3% of the cases. Many treatments were used, but recently good results were obtained by the association of Heller's cardiomyotomy with modified Lortat-Jacob's technique and left hemicolectomy.
