ABSTRACT
We evaluated the performances of three methods (urease-test, cytology and culture) for the detection of Helicobacter pylori infection Fifty-five patients, 28 men and 27 women (ages, 19-77 years) were included in the study. Helicobacter pylori have been detected by urease-test in 41 patients (74.5%), by culture in 39 patients (70.9%), by cytology in 32 patients (58.1%). Urease-test and culture are direct and specific methods in diagnosing Helicobacter pylori infection.
ABSTRACT
The Authors describe a rare case of esophageal stenosis complicated by gastroesophageal reflux due to Trichosporon beigelii in the absence of a pathologic predisposition or immunodeficiency. The diagnosis was drawn by embedding membrane fragments obtained endoscopically in Sabouraud and blood-Agar cultures. The patient was treated with antimicotics, immunostimulants, inhibitors of the gastric protonic pump, prokinetics and later underwent endoscopic dilatation combined with Savary-Guillard and pneumatic dilatators of growing diameter, until complete "restitutio ad integrum" of the esophageal lumen.
