Treatment of acute hypercalcemia.

Acute hypercalcemia is a life-threatening rather rare condition. This condition may represent an acute decompensation of a pre-existing hypercalcemia, or may be acute at the first instance of the electrolyte disturbance. Hypercalcemic patients can present with a broad spectrum of symptoms, but most of them are mild and non-specific.

Blood flow changes in hepatocellular carcinoma after the administration of thalidomide assessed by reperfusion kinetics during microbubble infusion: preliminary results.

Objectives: We sought to investigate whether thalidomide is able to produce tumor vascular changes in patients with untreatable hepatocellular carcinoma (HCC) that can be detected using microbubble contrast agents.

Materials And Methods: Eleven consecutive patients with untreatable HCC underwent contrast-enhanced ultrasound before and during thalidomide administration. Real-time destruction reperfusion kinetics was obtained from a representative HCC nodule and from the surrounding liver parenchyma during SonoVue infusion (Bracco, Milan, Italy) at a constant rate of 0.

Interferon plus ribavirin in patients with hepatitis C virus positive mixed cryoglobulinemia resistant to interferon.

Objective: Only a small fraction of patients with hepatitis C virus (HCV) positive mixed cryoglobulinemia achieve longterm recovery after interferon (IFN) therapy; we evaluated the effectiveness and safety of combination therapy (interferon plus ribavirin) in nonresponders or those who relapsed after one or more courses of IFN.

Methods: Twenty-seven patients with HCV positive mixed cryoglobulinemia were studied. All were treated with IFN-a2b (3 MU 3 times weekly) for one year, plus daily oral ribavirin 1000 or 1200 mg.

Excessive apoptosis, increased phagocytosis, nuclear inclusion bodies and cylindrical confronting cisternae in bone marrow biopsies of myelodysplastic syndrome patients.

Transmission electron microscopic (TEM) studies have not been reported in bone marrow (BM) biopsies of patients with myelodysplastic syndromes (MDS) owing to failure to overcome the technical impediment of maintaining ultrastructural detail in decalcified tissue. Using a modified technique to physically separate pieces of bone from marrow tissue under a dissecting microscope, and embedding the material directly for TEM, ultrastructural studies were performed in 15 MDS patients and four normal BM biopsies. Biopsy tissue was also used to initiate long-term in vitro cultures and 12-week plates were sacrificed for TEM analysis.
