Leg ulcers in elderly on hydroxyurea: a single center experience in Ph- myeloproliferative disorders and review of literature.

Hydroxyurea (HU) is effective in controlling thrombocytosis while reducing the risk of thrombosis in essential thrombocythemia (ET), polycythemia vera (PV) and myelofibrosis (MF). However, HU may carry more or less severe side-effects. Rare cases of patients with painful leg ulcers have been published.

Toxicity and side effects of hydroxyurea used for primary thrombocythemia.

Over the last 20 years a vast array of data has been accumulated on the efficacy of hydroxyurea (HU) in patients with Philadelphia-negative myeloproliferative disorders (MPD). However, several side effects have been described as well. Besides many anecdotal reports, no evaluation of their prevalence and type exists in large series of treated patients.

Main clinical manifestations of a bleeding diathesis: an often disregarded aspect of medical and surgical history taking.

A suitable clinical evaluation of a bleeding diathesis is often forgone. The young doctor is often unprepared to describe in an accurate way the different types of bleeding. An adequate classification and adequate clinical information about a bleeding diathesis are instead of paramount importance.

Safety profile of hydroxyurea in the treatment of patients with Philadelphia-negative chronic myeloproliferative disorders.

The efficacy of hydroxyurea (HU) in myeloproliferative disorders is well documented. HU controls thrombocytosis both in polycythemia vera (PV) and in essential thrombocythemia (ET), while reducing the risk of thrombosis.1 Despite many anectodal reports, no evaluation of the prevalence and type of side effects of HU exists in large series of patients.
