Approximately 2% of the general population have an underlying inherited bleeding disorder, which, for adolescents and young adult women, has both physical risks and adverse psychosocial effects. Heavy menstrual bleeding can be the first sign of an underlying bleeding disorder such as von Willebrand disease and the X-linked bleeding disorders hemophilia A and B. Connective tissue disorders such as Ehlers-Danlos syndrome, in particular the hypermobile subtype, are relatively frequent in the general population and can also cause bleeding symptoms from impaired hemostasis due to defective collagen.

Purpose Of Review: To summarize the recent literature related to female hemophilia A carriers with respect to prevalence in the population, the impact of baseline factor VIII levels and other influences on bleeding phenotype, and clinical management needs.

Recent Findings: Many female hemophilia A carriers are at risk for abnormal bleeding, yet they are underrecognized by healthcare providers and their bleeding symptoms are underreported. Low FVIII levels are consistently associated with clinically significant bleeding and correlate well with skewed X chromosome inactivation (XCI).

Background: Sorafenib promotes apoptosis through downstream pathways that can be deregulated in CRPC. We hypothesized that sorafenib could overcome chemotherapy resistance in CRPC.

Patients And Methods: Eligible patients were those whose disease had progressed during chemotherapy (docetaxel or mitoxantrone) or within 12 weeks of stopping either.

Diffuse large B-cell non-Hodgkin lymphoma (DLBCL) is a disease of the elderly, but our current guidelines and treatment paradigms for this disease are based on studies that have mainly enrolled younger patients. Because the number of people living beyond the age of 80 increased by more than 250% between 1960 and 2000, and since it is expected that the population over the age of 75 will triple by 2030, understanding how these elderly patients should be treated is paramount to improving outcomes for this potentially curable lymphoma. In this review, we outline the scope of the problem; we define "the elderly" and identify challenges in assessing this patient population.
