Screening tests for IG g antibodies against Helicobacter pylori are usefull for a long follow up of patients who were well eradicated. The aim of this study was to determinate and compared sensibility, specificity, positive and negative predictive value of six qualitative serological tests for IG g antibodies detection in the diagnosis of H. Pylori infections. Between May and October 1996 52 patients (30 males and 22 females; median age 42.4 years, range 21-68) with H. Pylori infection assessed on two antral and two corpus biopsies by means of Giema stain and a rapid urease test were tested for IG g antibodies detection. The serological tests used were: Inmunocomb II (Orgenics) Enzimo Inmuno Assay Inmunoadsorbent qualitative, Flex Pack (Smith Kline Diagnostics, Abbott) inmunocromatographic cualitative, Pylori Stat test (Biowhittaker) Enzimo Inmuno Assay (ELISA) qualitative, Premier (Meridian Diagnostics) Enzimo Inmuno Assay ELISA) qualitative. Pyloristest (Orion Diagnóstica) latex aglutination qualitative, H. Pylori (Bio Tre) Enzimo Inmuno Assay cualitative. 10 healthy subjects with negative gastric biopsies and negative rapid ureasa test were used as control group. The six evaluated serological tests have a comparable sensibility (89-95%) and specificity (77-83%) for the diagnosis of HP infection. The presence of specific HP antibodies in infected patients revealed a strong correlation with the histological demonstration of the microrganisms. We can recommend this qualitative serological tests due to their high sensibility and specificity, simplicity and low cost.

During the period included between January 1970 and December 1990, we studied 242 patients with manometric and radiological diagnosis of esophageal achalasia. Eight of these patients (3.3%) developed during the evolution of their disease an esophageal carcinoma. Eight cases showed histologic type of epidermoid carcinoma: 3 differentiated, 3 semi-differentiated and 2 anaplastic. Therapy for achalasia was: one patient, Heller myotomy, 4 patients, dilatations with bougies in numerous opportunities, and the other two patients receive no treatment for achalasia. Two patients reported tracheobronchial fistulas as complication of carcinoma. Treatment received for carcinoma included: three patients, radiotherapy (4000 rads); one patient, chemotherapy; one patient, chemotherapy and radiotherapy, one resection surgery and two patients feeding gastrostomy. All of the eight patients died within the year of diagnosis of epidermoid carcinoma.
