The in vitro effect upon platelet aggregation of estradiol and synthetic estrogens (prolame, buame, and proacame) is described. Prolame and buame produced a dose-dependent inhibition on platelet aggregation. Estradiol and proacame did not show anti-aggregating effects. The results suggest that the use of prolame and buame in estrogen therapy could reduce the risk of thrombo-embolic accidents.

Antiphospholipid syndrome is a well-defined clinical and serological entity characterized by arterial and/or venous thrombosis, recurrent abortion and thrombocytopenia. Anticardiolipin antibodies and lupus anticoagulant are autoantibodies directed against negatively charged phospholipids, which represent the serologic criteria for the diagnosis of the antiphospholipid syndrome. In this review the pathogenic mechanisms of anticardiolipin antibodies, their clinical findings and the current therapeutical strategies are discussed.
McArdle's disease (glycogenosis type V) is a metabolic disorder of hydrocarbons, inherited with autosomic recessive pattern. Biochemically is defined by a myophosphorylase deficiency; clinically it is characterized by exercise intolerance, due to the impossibility of providing energetic substrate to the muscle, myalgias and stiffness. We present a case report of a patient with McArdle's disease and we comment the diagnostic procedures and current therapeutic options.
