Transient efficacy of octreotide and pasireotide (SOM230) treatment in GIP-dependent Cushing's syndrome.

We studied a 55-year old woman presenting with features of Cushing's syndrome associated with metabolic abnormalities including severe hypertension and type 2 diabetes. Urinary free cortisol excretion was within normal limits, but an unusual diurnal cortisol rhythm was observed with low morning and high postprandial levels, associated with the absence of cortisol suppression after dexamethasone, suggesting the possibility of GIP-dependent Cushing's syndrome. The diagnosis was confirmed by further investigations, showing significant plasma cortisol responses after a mixed meal test and after oral, but not intravenous glucose administration, as well as ACTH-independent bilateral macronodular adrenal hyperplasia (AIMAH).

Chronic lymphocytic leukemia with portal hypertension and without liver involvement: a case report underlining the roles of increased spleno-portal blood flow and "protective" sinusoidal vasoconstriction.

We report the case of a 72-year-old woman with well-controlled chronic lymphocytic leukemia (CLL) and splenomegaly who developed portal hypertension with bleeding oesophageal varices in the absence of liver fibrosis or regenerative nodular hyperplasia at surgical wedge liver biopsy. The hepatic venous pressure gradient (HVPG) was elevated and splenectomy resulted in both its normalisation and the regression of oesophageal varices. This case shows the potential for an increased spleno-poral flow to generate severe portal hypertension likely through a "protective" sinusoidal vasoconstriction.

[Epidemic of hantavirus disease in Entre-Sambre-et-Meuse: year 1992-1993. Clinical and biological aspects].

A multihospital study allowed us to follow a total of 62 serologically proven cases of Nephropathia epidemica (NE) in the Belgian region between Sambre and Meuse during the 1992-1993 period. The clinical picture consisted of sudden high fever (100% of the cases), headache (71%), abdominal or lumbar pains (80%) and, as a less frequent but very specific sign, acute myopia (24%). Non-specific respiratory symptoms such as a non-productive cough and an abnormal lung auscultation were found in 1 case out of 4.
