[Immunopathological characteristics of the lymphocytes of chronic lymphocytic leukemia, fractionated on gradients of various densities].

Spontaneous rosettes and membrane immunofluorescence for the various classes of heavy and light immune globulin have been determined on lymphocyte subfractions obtained from the blood of 6 normal subjects and 16 patients with CLL by separation on gradients of various density. Whereas in the normal subject lymphocyte immunological features proved similar in all fractions, in CLL they presented significant differences from fraction to fraction, with the presence only in certain fractions of the lymphocyte peak with monoclonal membrane immune globulin and without peak coincidence for IgD and IgM, probably as a result of changes in the physico-chemical features of the lymphocytes occurring during maturation. All fractions presented a sizeable complement of lymphocytes not forming rosettes and without demonstrable membrane immune globulins. The correlation between the behaviour of membrane labels and lymphocyte morphology, stage, duration and course of the disease has been analysed. The variability in lymphocyte subfraction characteristics separable at different densities may explain discrepancies of findings in researches carried out in lymphocytes that separate only at gradient of density 1077.

Hemiballism in a patient with probable multiple system atrophy.

We report a patient with long-standing asymmetrical parkinsonism, cerebellar ataxia and dysautonomia, suggestive of multiple system atrophy (MSA). However, the patient also developed involuntary repetitive movements similar to ballic dyskinesias and mental deterioration. MRI revealed major involvement of both posterior fossa structures and basal ganglia. The case would be accommodated within a rubric of MSA widened to include involvement of the subthalamic nucleus and the medial part of the pallidum, pathology which may account for the ballic movements. Additionally the patient's cognitive and behavioural disturbances suggest an impairment of striato-prefrontal cortex loop.

Extravasation of liposomal daunorubicin in patients with AIDS-associated Kaposi's sarcoma: a report of four cases.

PURPOSE/OBJECTIVES: To report on four patients with AIDS-related Kaposi's sarcoma who were treated with liposomal daunorubicin (DaunoXome, NeXstar Pharmaceuticals, Inc., San Dimas, CA) as part of phase I/II and phase III clinical trials and who experienced extravasation during IV infusion. DATA SYNTHESIS: All patients were treated with ice as an immediate intervention. In addition, two patients received treatment with multiple subcutaneous injections of steroids. Two patients experienced erythema, swelling, and pain after the extravasation. Two patients who were treated aggressively reported erythema and swelling without pain. Three patients observed changes in the texture of their skin that was accompanied by decreased sensation, which developed after 8-16 weeks. These changes completely resolved in all patients receiving intervention after six months. None of the patients suffered tissue necrosis. CONCLUSIONS: Extravasation with liposomal daunorubicin is notable for the absence of tissue necrosis that typically is observed with anthracyclines. Long-term effects were limited to skin discoloration and decreased sensation, both of which resolved in all patients. IMPLICATIONS FOR NURSING PRACTICE: The lack of observed skin necrosis with daunorubicin suggests a treatment advantage with a reduction in the required aggressive extravasation procedures for free anthracyclines as well as increased safety for the patient. Additional data is needed to confirm these observations.
