A case of acquired double pyloric channel in a 62-year-old man is reported, with a review of the available literature on the topic. Double pylorus or gastroduodenal fistula is a rare condition, nearly always following a penetrating and fistulous ulcer; there is no particular or autonomous clinical picture, and the diagnosis is usually made by means of radiology and endoscopy.

The lipid islands in the gastric mucosa are small, well delimited white or yellowish-white patches varying in diameter from 0.5 to 3 millimeters. Microscopically they constitute accumulations of macrophages full of lipids. This endoscopic and histological finding was observed in 0.38% of patients who had not undergone gastric resection, and in 18.0% of those who had the intervention, the basis being a case-list of 1381 endoscopic examinations of the upper digestive tract. The endoscopic and histological aspects and the clinical correlations of the gastric lipid islands are discussed, emphasizing the importance of biliary reflux as an etiological factor. The presence of gastric lipid islands must be considered as the expression of a prolonged inflammatory process of the gastric mucosa.
Two cases of primary and isolated gastroduodenal candidiasis are described. The diagnosis of the mycotic infection was based on the discovery of hyphae in the biopsy obtained through the gastroscope (Olympus GIF-K). Clinical, endoscopic and histologic appearances are discussed.
Three cases of urologically silent Grawitz' tumour detected by a pathological blood picture marked by marrow plasmacytosis are presented. The importance of paraneoplastic syndromes in this tumour form is discussed. The association observed is common and its classification as a paraneoplastic syndrome is examined.

UNLABELLED: Hepatic hematomas, after liver biopsy, are collections of blood within the hepatic parenchyma and/or the hepatic capsula. The frequency of hematomas is reported to vary from 0% to 23% as a consequence of the patient selection and/or of the different diagnostic techniques (angiography, isotope techniques, ultrasound and CT scan). AIM: To study prospectively, using the ultrasound scan, the incidence and the clinical significance of hematomas. METHODS: 115 liver punctures were prospectively studied; before and 24 hours after the procedure the patients were submitted to liver US scan and CBC, transaminase and bilirubin were also checked. RESULTS: The procedure was unsuccessful in one patient and none had more than one needle pass; five patients had two biopsies in different sessions. The 24 hour post-biopsy liver US scan did not show any hepatic hematomas. No patient had a significant drop in hemoglobin or in red blood cells. CONCLUSIONS: Hepatic hematomas after liver biopsy are uncommon and of little clinical significance.
