Long-term effects of eradication of Helicobacter pylori on relapse and histology in gastric ulcer patients: a two-year follow-up study.

Background: The main purpose of this study was to compare omeprazole (ome) plus two antibiotics (OMC) with omeprazole plus placebo (OP) with regard to gastric ulcer relapse for a period of 2 years in patients who were Helicobacter pylori-positive at inclusion.

Methods: Using double-blind randomization 125 patients with gastric ulcer were treated with either OMC (ome 20 mg b.i.

Short-term starvation alters the free amino acid content of the human intestinal mucosa.

1. The effects of short-term starvation and refeeding on the free amino acid concentrations of the intestinal mucosa were characterized in male subjects (n = 6), using endoscopically obtained biopsy specimens from the duodenum and from all four segments of the colon. 2.

Absence of Helicobacter pylori in dental plaques in Helicobacter pylori positive dyspeptic patients.

To test the validity of reports on detection of Helicobacter pylori in the mouth, samples were obtained simultaneously from the gastric mucosa and dental plaques for culture in 94 patients examined consecutively by endoscopy. Histological examinations and serological tests were also performed. Helicobacter pylori was not found in the mouth of any of the patients including 52 who had culture-positive gastric biopsies.

Gray-scale sonography in torsion of the testicular appendages.

The reliability of gray-scale ultrasonography in diagnosing torsion of the testicular appendages was studied in a series of 54 boys with acute non-traumatic scrotal pain. All boys were operated upon, and the appendages extirpated irrespective of their appearance at exploration; the final diagnosis was based on histological examination. Forty-two boys had appendicular torsion, 2 had testicular torsion and 10 had other diagnoses.

Immunochemical and immunohistochemical evaluation of lung permeability in ventilated newborn rabbits.

These experiments were designed to quantify the vascular-to-alveolar leakage albumin in the neonatal lung and to analyze the distribution of leaking airspaces in the lung parenchyma. Immediately after delivery, newborn rabbits with gestational age 27-29 days received an intravenous injection of human albumin as a marker and were ventilated for 15 min with standardized tidal volume (10 ml/kg). After the period of ventilation the lungs were either lavaged via the airways or fixed for histological studies.

Liver resection with the Sonocut ultrasonic knife.

Previous reports and our findings suggest that resection by ultrasound is of appreciable merit in liver surgery. Blood can be saved and bile leakage diminished as the larger vessels and bile ducts can be skeletonized unharmed, whereas the dissector selectively carries away the parenchyma. Otherwise virtually inaccessible tumours can be approached.

Polyarteritis nodosa of the penis.

The course of polyarteritis nodosa in a patient showing an isolated nodule localized to the glans penis is described. The underlying disease was not recognised and the patient was wrongly thought to have a penile cancer. Treatment with radiotherapy and Bleomycin had no effect and he subsequently died in uraemia.
