[Lyme disease presenting as infarction pain. A case report]. / Douleur infarctoïde révélant une maladie de Lyme. A propos d'un cas.

Lyme's disease is a multi-system condition due to infection with a spirochete (Borrelia Burgdorferi), transmitted by a tick. Cardiac involvement, which is not systematic, usually presents with transient atrioventricular block of varying degree. The authors describe an unusual presentation of the cardiac involvement of Lyme's disease with chest pain resembling an acute coronary syndrome in a 32 year old man. The characteristic skin lesion (erythema migrans), the positivity of IgM serology, the myocardial scintigraphic results and the negativity of the work-up of other causes of this pain led to a diagnosis of myocarditis, the outcome of which was favourable with treatment by amoxycillin (3 g/day, orally).

[Thoraco-cervicofacial purpura caused by thoracic compression: a new Perthes syndrome?]. / Purpura thoracocervicofacial par compression thoracique: un nouveau syndrome de Perthes?

A case of a major thoracocervicofacial purpura in a 16-year-old patient following a prolonged thoracic compression by his motor car is reported. The causative mechanism, equivalent to a Valsalva manoeuvre is discussed. As the first case has been described and analyzed by Perthes, the authors suggest to call it "Perthes syndrome".
