Troubles du contrôte des impulsions et maladie de Parkinson [Impulse control disorders and Parkinson's disease].

A variety of behavioral disorders occurring abruptly in patients with Parkinson's disease (PD) has been recently published and attracted considerable attention in the press. Taking the form of pathological gambling, compulsive shopping, addiction to Internet and to other recreational activities, hypersexuality or bulimia, impulse control disorders (ICD) related to PD are probably more frequent than previously appreciated and may have consequences as spectacular as disastrous for the involved patients. ICD are currently viewed as particular adverse reactions to antiparkinsonian medications, notably to dopamine agonists, and, accordingly, tend to improve or disappear when PD therapy is appropriately adjusted.

Laryngospasme: présentation inhabituelle d'une maladie coeliaque [Laryngospasm: unusual manifestation of celiac disease]

Gluten-induced enteropathy or coeliac disease is a condition characterized by malabsorption and a variety of clinical manifestations. In adults, coeliac disease may be discovered while investigating iron-deficient anemia, bone pain or unexplained weight loss. We have recently diagnosed a case of gluten-induced enteropathy in an elderly woman whose symptoms were unusual. The patient had episodes of laryngospasm secondary to severe hypocalcemia and hypomagnesemia. The malabsorption syndrome was responsible for low levels of vitamin D, causing the electrolytic imbalance. Laryngospasm is a rare symptom of hypocalcemia and has not, to our knowledge, been described in the context of coeliac disease.
