The frequency and characteristics of esophageal dysmotility in Sjögren's syndrome (SS) are as controversial as their related symptoms. We evaluated esophageal function and gastroesophageal reflux (GER) in 21 SS patients using manometry and 24-hr esophageal pH monitoring. All patients complained of xerostomia, 33% of dysphagia, and 62% of heartburn. Compared(More)
Sixty-one patients with gastroesophageal reflux who did not respond to conventional medical treatment were treated in a prospective study, 29 by conventional surgery and 32 by laparoscopic methods. All underwent manometry and pH measurement preoperatively and at a follow-up of four months. There was no mortality, and the morbidity of the two groups was not(More)
BACKGROUND This study was conducted to determine whether the major nasal airway ion transport abnormalities in cystic fibrosis (that is, defective cAMP regulated chloride secretion and basal sodium hyperabsorption) are related to the clinical expression of cystic fibrosis and/or to the genotype. METHODS Nasal potential difference was measured in 79 adult(More)
Gastro-oesophageal reflux was demonstrated in 5 cases of bronchiolitis obliterans with apparently cryptogenetic organizing pneumonia. In addition, one patient had hiatus hernia and another, oesophageal diverticulum. In 4 patients, after failure of prolonged antibiotic therapy, medical or surgical treatment of the gastro-oesophageal reflux resulted in(More)
Off-line computer assistance allowed a correct visualization of the actual data included in any experimental whole oxygen-hemoglobin association curve. The affinity of hemoglobin for oxygen (characterized by the successive PO2 corresponding to any saturation value: P(SO2)), the shape of the association curve (Hill's curve and Hill's numbers) and the Bohr(More)
Respiratory disorders in homozygous drepanocytosis and double SC heterozygosis are mainly dependent on two factors : repeated infections with, more particularly, pneumococcus or mycoplasma, and epidoses of occlusion of the pulmonary circulation. Mutual reinforcement of these two factors occurs, in so far as the relative hypoxia of an infected lung increases(More)
