Frontotemporal dementia as the presenting phenotype of p.A53T mutation carriers in the alpha-synuclein gene.

Introduction: The p.A53T point mutation in SNCA, the alpha-synuclein gene, has been linked to a rare dominant form of Parkinson's disease (PD).

Methods: Here, we describe two apparently unrelated cases of p.

Strontium-89 chloride in the treatment of bone metastases from breast cancer.

Sixty-four patients with painful metastatic breast cancer in bone were treated with 2 MBq/kg of strontium-89 chloride as a single intravenous injection. Patients were followed with records of medication, hematology parameters, serial bone and Sr-89 bremsstrahlung images and with a point pain score scale (10-0). The response was assessed during a 6-month period of follow-up.

Technetium-99m teboroxime scintigraphy. Clinical experience in patients referred for myocardial perfusion evaluation.

In order to evaluate the clinical value of a new myocardial perfusion tracer, a series of 30 patients (25 male, 5 female, mean age 56 years) referred for thallium 201 stress/redistribution scintigraphy has been studied using stress/rest (n = 7) or rest/stress (n = 23) protocols with technetium 99m teboroxime (Cardiotec SQUIBB). In all cases coronary artery disease was known or highly probable, with a history of myocardial infarction in 18 cases. Medical treatment was not discontinued at the time of stress testing, and coronary angiography was available in 27 patients.
