Fournier's gangrene (FG) is a rare but severe necrotizing fasciitis of the external genitalia that may complicate the clinical course of hematologic malignancies and sometimes may be the first sign of the disease. The clinical course of FG is very aggressive and the mortality is still high despite the improvement in its management. Early recognition of FG and prompt appropriate treatment with s...

Imatinib and recombinant interferon alpha (rIFNalpha) can induce remission in polycythemia vera (PV) patients, but gauging the depth of responses has not been possible due to lack of a specific disease marker. We found that patients undergoing imatinib (n = 14) or rIFNalpha (n = 7) therapy remained strongly positive for V617F JAK2, although there was a significant reduction in the median percen...

Systemic mastocytosis is a disease of mast cell proliferation that may be associated with hematologic disorders. There are no features on examination that allow the diagnosis of systemic disease, and mast cell-derived mediators, which may be elevated in urine or blood, may also be elevated in individuals with severe allergic disorders. Thus, the diagnosis usually depends on results of bone marr...

OBJECTIVES Patients with hematologic malignancies are frequently in need of major cardiac operations. Previous reports suggest an increased risk for perioperative complications in these immunodeficient patients. METHODS Patients diagnosed with any type of hematologic malignancy who underwent open-heart surgery at our institution between 7/1996 and 6/2002 were identified. Their hospital charts...

Invasive fungal disease represents a major complication in hematological patients. Antifungal agents are frequently used in hematologic patients for different purposes. In neutropenic patients, antifungal agents may be used as prophylaxis, as empiric or preemptive therapy, or to treat an invasive fungal disease that has been diagnosed. The hematologist must be familiar with the epidemiology, di...

Admission of a patient to an intensive care unit for management of direct consequences of a hematologic or oncologic disease is occasionally necessary. Such problems included exchange transfusion, sepsis, compression of vital structures by malignant tumor, metabolic derangements, leukostasis, post-operative care, major sickling episodes in vital organs, and disseminated coagulopathy. More often...

Hematologic complications of HIV disease are commonly encountered by physicians and other health-care workers caring for patients infected with this virus. Ineffective hematopoiesis, infiltrative diseases of the bone marrow, nutritional deficiencies, peripheral destruction of blood cells secondary to splenomegaly or immune dysregulation, and drug effects all contribute to the variety of hematol...

We present a case of disseminated cryptococcal disease, coexisting with and mimicking lymphoma. Determination of serum cryptococcal antigen should be considered for lymphopenic patients with hematologic malignancies, presenting with unexplained fever, and/or lymphadenopathy and/or pulmonary findings. Patients with hematologic malignancies treated with chemotherapy regimens are susceptible to di...

Multiple myeloma (MM) is a malignant hematologic disorder involving plasma cells. In MM, immunoglobulin is overproduced, and patients can develop skeletal, hematologic, renal, and/or neurologic complications. The exact etiology of MM is unknown. The treatment for MM includes chemotherapy, antiangiogenic medications, and, most recently, a proteasome inhibitor. Nursing care for patients with MM r...
