Acute Transient Sixth Nerve Palsy in Chediak-Higashi Syndrome.

Neurologic disorders in Chediak-Higashi syndrome are usually late presentations and also may manifest long after bone marrow stem cell transplantation. To the authors' knowledge, transient neurological deficit has not been reported yet. They describe a 6-year-old boy with Chediak-Higashi syndrome in the accelerated phase who presented with transient sixth nerve palsy.

Moderate pulmonary embolism treated with thrombolysis (from the "MOPETT" Trial).

The role of low-dose thrombolysis in the reduction of pulmonary artery pressure in moderate pulmonary embolism (PE) has not been investigated. Because the lungs are very sensitive to thrombolysis, we postulated that effective and safe thrombolysis might be achieved by a lower dose of tissue plasminogen activator. The purpose of the present study was to evaluate the role of this "safe dose" thrombolysis in the reduction of pulmonary artery pressure in moderate PE.
