BACKGROUND Waldenström's macroglobulinemia may be complicated by retinal hemorrhages, retinal vein occlusion, serous macular detachment or macular edema. We report a patient with pseudovitelliform subfoveal deposit complicating Waldenström's macroglobulinemia. CASE REPORT A 56-year-old man presented with hyperviscosity syndrome due to Waldenström's macroglobulinemia. After systemic therapy, a...

PURPOSE To report the case of a 48-year-old man with unilateral central retinal vein occlusion. METHODS The clinical, hematologic and hypercoagulability evaluations of the patient were thoroughly and specifically carried out. RESULTS The central retinal vein occlusion was of nonischemic type and was associated with polyglobulia, hyperleukocytosis, hypercholesterolemia, multiple dental foci,...

The estimate derived by Henshaw, Kreiss, and Reyna for the smallest scale present in solutions of the two-dimensional incompressible Navier-Stokes equations is employed to obtain convergent pseudospectral approximations. These solutions are then compared with those obtained by a number of commonly used numerical methods. If the viscosity term is deleted and the energy in high wave numbers remov...

Six patients with various forms of leukaemia had neurological signs and symptoms associated with an extremely high white blood cell count and increased whole blood (but not plasma) viscosity. All were treated by leucapheresis with an Aminco Celltrifuge. Rapid and complete reversal of all symptoms occurred in three patients and partial recovery in one. One patient died shortly after leucapheresi...

Asparaginase is a chemotherapeutic agent used to induce disease remission in children with acute lymphoblastic leukemia (ALL). We describe the cases of two females with ALL who developed pseudohyponatremia as a presentation of hypertriglyceridemia following asparaginase treatment. Nine similar published cases of asparaginase-induced hypertriglyceridemia and its complications are also discussed....

Forty patients with atherosclerotic peripheral vascular disease, as compared to 29 healthy controls, showed a significant increase in platelet number and activity, a neutrophil leucocytosis, and a raised level of several acute-phase reactant proteins (fibrinogen, antithrombin III, factor VIII, and serum globulin). The hyperproteinaemia was associated with increases in plasma-, serum-, and blood...

Despite the absence of randomized trials, plasmapheresis has consistently demonstrated efficacy in treatment of Waldenström's macroglobulinemia (WM) patients with hyperviscosity syndrome (HVS). This procedure can promptly reverse most clinical manifestations of serum HVS. Early diagnosis is crucial and usually can be made from the funduscopic exam. Serial viscosity measurements can be monitored...

Forty patients with Waldenstr#{246}m’s macroglobulinemia were evaluated for criteria of diagnosis, clinical presentation and course. response to therapy, and appropriateness of the classification primary or secondary. A wide spectrum of presentations, course, and complications were present. Thus, the major criteria for diagnosis was a monoclonal 1gM serum protein abnormality present in concentr...
