Cerebral Protection During Mitral Valve Repair in a Patient With Moyamoya Syndrome.

In patients with moyamoya syndrome requiring heart surgery, the brain blood flow during the low perfusion state under cardiopulmonary bypass is a concern. We report on a successful mitral valve repair and tricuspid repair in a patient with moyamoya syndrome, performed using an integrated cerebral protection strategy with cerebral oxygen saturation monitoring, intraaortic balloon pumping, and cardiopulmonary bypass perfusion at a relatively high pressure. An integrated approach with a thorough discussion among cardiac surgeons, anesthesiologists, and perfusionists was invaluable to protect brain perfusion in a patient with moyamoya syndrome.

Myeloablative allogeneic hematopoietic stem cell transplantation for non-Hodgkin lymphoma: a nationwide survey in Japan.

We retrospectively surveyed the data of 233 patients who underwent myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) for non-Hodgkin lymphoma (NHL). Donors were HLA-matched relatives in 154 patients (66%) or unrelated volunteers in 60 (26%). Ninety patients (39%) were in complete remission.

Severe hypercholesterolemia associated with decreased hepatic triglyceride lipase activity and pseudohyponatremia in patients after allogeneic stem cell transplantation.

A 55-year-old woman with Ph-negative acute lymphoblastic leukemia in primary induction failure received allogeneic peripheral blood stem cell transplantation from her HLA-compatible sister. Pseudohyponatremia developed due to extreme hypercholesterolemia of 4091 mg/dL accompanied by lipoprotein X and lipoprotein Y. The hypercholesterolemia was caused by cholestasis due to chronic GVHD and ischemic cholangiopathy.

Allogeneic haematopoietic stem cell transplantation as a promising treatment for natural killer-cell neoplasms.

The efficacy of allogeneic haematopoietic stem-cell transplantation (allo-HSCT) for natural killer (NK)-cell neoplasms is unknown. We investigated the results of allo-HSCT for NK-cell neoplasms between 1990 and 2003 through questionnaires. After reclassification by a haematopathologist, of 345 patients who underwent allo-HSCT for malignant lymphoma, 28 had NK-cell neoplasms (World Health Organization classification): extranodal NK/T-cell lymphoma (n=22), blastic NK-cell lymphoma (n=3), and aggressive NK-cell leukaemia (n=3).

Impact of cytogenetics on outcome of stem cell transplantation for acute myeloid leukemia in first remission: a large-scale retrospective analysis of data from the Japan Society for Hematopoietic Cell Transplantation.

On the basis of transplantation data from the Japan Society for Hematopoietic Cell Transplantation, we retrospectively analyzed the impact of cytogenetics at diagnosis on the outcome of transplantation in 628 patients with acute myeloid leukemia who underwent autologous (n = 200), allogeneic related (n = 363), or allogenic unrelated (n = 65) stem cell transplantation (SCT) at first complete remission. For autologous SCT, patients at good cytogenetic risk had a significantly lower relapse rate (P = .017) and a significantly higher event-free survival (EFS) (P = .

Allogeneic hematopoietic stem cell transplantation from family members other than HLA-identical siblings over the last decade (1991-2000).

The reported outcome of hematopoietic stem cell transplantation (HSCT) from HLA-mismatched family members has been inconsistent. The object of this study was to evaluate the true impact of HLA-mismatch by using recent data from a homogenous population, excluding HSCT procedures that used graft manipulations, and by considering genotypic matching. Clinical data of 2947 patients who underwent allogeneic HSCT for leukemia or myelodysplastic syndrome were extracted from the database of the Japan Society for Hematopoietic Cell Transplantation.

[Acute leukemia in two brothers].

A 42-year-old man was diagnosed as having refractory anemia in May, 2001. He developed overt leukemia and received allogeneic bone marrow transplantation (BMT). His younger brother, a 40-year-old man, was diagnosed as having acute leukemia with trilineage myelodysplasia in November, 2001.
