Thrombosis in a bleeding disorder: case of thromboembolism in factor VII deficiency.

Congenital factor VII deficiency (FVIID) is a rare disorder with a wide range of bleeding manifestations. The disorder does not protect patients against occurrence of thrombosis, and deep vein thrombosis can occur in the setting of surgery and recombinant factor VIIa replacement.

Successful management of a possible antibiotic-related acquired factor V inhibitor: a case report and review of the literature.

Acquired factor inhibitors are rare. We report a case of an elderly male who presented with a bleeding diathesis associated with an elevated prothrombin time and an activated partial thromboplastin time. Work-up revealed undetectable factor V activity and a factor V inhibitor level of >50 Bethesda units.

Unexplained bone marrow granulomas: is amiodarone the culprit? A report of 2 cases.

Granulomas in the bone marrow are usually caused by infectious or hematological diseases, and drugs are only rarely implicated as causative agents. Recent reports have drawn attention to the role of amiodarone in the etiology of bone marrow granulomas. We report two cases of amiodarone-induced bone marrow granulomas in patients being investigated for refractory anemia and pancytopenia, respectively.

Development of a comparative genomic hybridization microarray and demonstration of its utility with 25 well-characterized 1p36 deletions.

Chromosomal abnormalities, such as deletions and duplications, are characterized by specific and often complex phenotypes resulting from an imbalance in normal gene dosage. However, routine chromosome banding is not sensitive enough to detect subtle chromosome aberrations (<5-10 Mb). Array-based comparative genomic hybridization (array CGH) is a powerful new technology capable of identifying chromosomal imbalance at a high resolution by co-hybridizing differentially labeled test and control DNAs to a microarray of genomic clones.

Physical map of 1p36, placement of breakpoints in monosomy 1p36, and clinical characterization of the syndrome.

Monosomy 1p36 is the most common terminal deletion syndrome. This contiguous gene deletion syndrome is presumably caused by haploinsufficiency of a number of genes. We have constructed a contig of overlapping large-insert clones for the most distal 10.

Acute myelogenous leukemia associated with extreme symptomatic thrombocytosis and chromosome 3q translocation: case report and review of literature.

Acute leukemias with thrombocytosis have been recently linked with structural abnormalities of the short arm of chromosome 3. A 46-year-old man with a 2-month history of recurrent transient ischemic attacks and abdominal pain developed an ischemic left foot and a gangrenous toe as his initial symptoms. Platelet count was 3.
