Serious infection is rare and patients respond well to granulocyte colony-stimulating factor. Severely neutropenic patients with HCV appear to have a benign course and may therefore be candidates for antiviral therapy. Copyright (C) 2012 S. Karger AG, Basel
POEMS syndrome is characterized by polyneuropathy, organomegaly, Inhibitors,Modulators,Libraries endocrinopathy, monoclonal gammopathy Inhibitors,Modulators,Libraries and skin changes. Bortezomib is an important component of the chemotherapy regimen associated with multiple myeloma, and has been previously applied to POEMS syndrome. We present a 56-year-old Chinese man who was given subcutaneous administration of bortezomib as part of the BDex (bortezomib-dexamethasone) regimen for his POEMS syndrome. The peripheral neuropathy and laboratory-test results of the patient improved dramatically with 4 cycles of treatment, resulting in a complete response.

In addition, the treatment was well tolerated and adequate peripheral blood hematopoietic stem cells were collected for an ensuing autologous stem cell transplant. Copyright (C) 2012 S. Karger AG, Basel
MYH9-related disease (MYH9-RD) is an autosomal dominant disorder caused by mutations in the MYH9 gene. It is characterized by a triad of giant platelets, Inhibitors,Modulators,Libraries thrombocytopenia, and characteristic Dohle Inhibitors,Modulators,Libraries body-like granulocyte inclusions. In this study we report 10 unrelated patients with MYH9-RD in whom the following seven MYH9 gene mutations were found: W33R, p.Q1443_K1445dup, R702H, D1424N, E1841K, R1933X, and E1945X (the first two were novel mutations). The region of the MYH9 mutation determines in some regards the phenotype, but clinical expression can vary between individuals with the same mutation.

The neutrophil inclusion bodies of two patients were too small to be detected, but could be found with immunofluorescence staining. Immunoblotting analysis revealed that the calculated NMMHCIIA/beta-actin ratio for MYH9-RD neutrophils was 39% of normal controls. Kidney biopsy showed segmental glomerulosclerosis and NMMHC-IIA expression was decreased in podocytes. This GSK-3 disease is not as rare as originally thought. In any individual with persistent macrothrombocytopenia and no response to corticosteroids and immunosuppressive agents, even if neutrophil inclusions were inconspicuous in routine staining, MYH9-RD should be suspected.

Langerhans cell sarcoma (LCS) is extremely rare, with only 36 cases reported in English literature.

In this report we represent the case of a 77-year-old Tipifarnib cancer woman with a 1-month history of left neck swelling and pain. A diagnosis of LCS was rendered from pathological findings of the cervical lymph node biopsy. The patient’s condition deteriorated rapidly and she died 2 days after diagnosis. A literature review in the context of the present case was performed to better enhance understanding of the early diagnosis and treatment of this unusual lesion. Copyright (C) 2012 S.
