ABSTRACT

We studied 26 patients (p) with end stage renal failure (RF) and 26 healthy volunteers (HV) to investigate the prevalence of Helicobacter pylori (Hp) and its relation with chronic gastritis (CG) and chronic duodenitis (CD). We analyzed 312 gastric and duodenal mucosal biopsies stained with H & E and Giemsa. Categorical data were assessed by the X2 and Fisher's exact test. Probability values of p < 0.05 were considered significant. Endoscopic lesions correlated with histological gastritis and duodenitis and Hp was positive in antrum of 6/8p (75%) (p < 0.05). The prevalence of Hp was 54.5% (15/26p) in RF and 47.2% (12/26s) in HV. Hp was found more frequently in pathological mucosa (p < 005.). CG of the antrum and CD were more commonly in RF (88.5% vs 69.5% and 42.3% vs 23.1% respectively). HP was more frequently located in the antrum than in body and duodenum in both groups (p < 0.05). Chronic gastritis of the body was more frequently in HV (p < 0.05). Active chronic antral gastritis and superficial gastritis were more frequently associated to Hp. Hp was associated to chronic inflammatory gastroduodenal diseases in both groups and may be a cofactor in its pathogenesis. We recommended Hp treatment before renal transplantation.

ABSTRACT

A method is described for the processing of material obtained by fine needle aspiration. During the procedure, continuous aspiration, movement and rotation of the needle is performed in order to obtain at least 2 ml of material and blood. Samples are processed immediately for cytology and the rest of the material is left in the syringe until it coagulates. The clot is withdrawn from the syringe by retrieving the embolus and the formed material is introduced in formol and processed as usual for histology. This allows for the examination of all the material obtained by a pathologist who may not have experience in cytology.

ABSTRACT

This paper reports a case of an histological non aggressive thymoma with myasthenic symptoms as the first clinical manifestation. Three years after its complete surgical resection liver metastases appeared without evidence of intrathoracic neoplastic disease. The extrathoracic metastases are uncommon and the thymomatous myasthenia gravis is present in 25 to 50% of cases. We reviewed the literature and analyzed its clinical pathological characteristics and therapeutics approach.
