Abstract: The endoscopic features of the gastric mucosa in patients with cirrhosis have not been systematically investigated. In these patients, we observed an endoscopic aspect, consisting of multiple small erythematous areas, outlined by a subtle yellowish network (resembling a mosaic), mainly located in the proximal part of the stomach. We tested the value of this sign by comparing two groups: 100 patients with portal hypertension due to cirrhosis, and 300 control patients without signs of liver disease or portal hypertension. This endoscopic pattern was observed in 94 of the patients with cirrhosis, whereas oesophageal varices were seen in 78 only. In contrast, only one patient of the control group had this aspect. Moreover, this sign was also found in seven of eight patients with non cirrhotic portal hypertension, but was seen neither in 100 patients with chronic alcoholism but without liver disease, nor in 10 cirrhotic patients with end-to-side portacaval shunts. These endoscopic changes might be because of mucosal and/or submucosal oedema and congestion highlighting the normal areae gastricae pattern and related to raised portal pressure. We conclude that the mosaic pattern of the gastric mucosa is a sensible and specific sign for diagnosis of portal hypertension, whatever the cause.

Abstract: The prognostic value of marrow chromosome findings was examined in 242 patients with preleukemic myelodysplastic syndromes (MDS) or myeloproliferative disorders (MPD), with emphasis on the significance of single versus multiple karyotypic changes. In both groups, the results showed that patients with multiple chromosome abnormalities in a marrow clone had a very high probability of early death, from progression to leukemia or from other complications of hematopoietic dysfunction. Conversely, in patients with a hemic clone having only one karyotypic alteration (involving a single chromosome or single translocation), survival over 2 years was only slightly reduced as compared to those without chromosome abnormality. The only single karyotypic alteration perhaps associated with a markedly shortened survival was monosomy 7. These findings suggest that the conclusions of previous studies concerning the grave consequences of chromosome alterations in preleukemia largely reflect the clinical significance of clones with multiple cytogenetic changes. Prior knowledge of the karyotypic status of preleukemic patients should be helpful in evaluating current attempts to find effective treatment for these difficult disorders.

Abstract: Benign osteoblastoma is a rare, solitary, vascular, osteoid-producing tumor that is rich in osteoblasts. This is the first report of a case of osteoblastoma of the orbit not contiguous with a sinus cavity.
