Etiological study of polyclonal hypergammaglobulinemia in a French cohort of hospitalized patients and proposal of a diagnostic aid algorithm : Short title: polyclonal hypergammaglobulinemia in a French cohort of hospitalized patients.

Serum protein electrophoresis can sometimes reveal polyclonal hypergammaglobulinemia. This electrophoretic abnormality can be caused by a variety of conditions and can be difficult to investigate. We sought to investigate screening practices in patients with hypergammaglobulinemia in order to establish diagnostic guidance strategies.

Stability of Morphine Sulfate-Clonidine and Sufentanil-Clonidine Mixtures.

Background: Spinal analgesia is recommended for intractable cancer pain. Morphine-clonidine and sufentanil-clonidine are often used in association in intrathecal drug delivery systems, injected by intraabdominal pumps. To refill these pumps and to limit patient transport, it may be necessary to ship the mixtures in polypropylene syringes to peripheral establishments located near patient homes.
