[Psychopathological and psychotherapeutic approach to the first psychotic episode]. / L'approche psychopathologique et psychothérapeutique d'un premier épisode psychotique.

The studies and research on the psychopathology of delusions are extremely numerous and varied and have resulted in the construction of psychoanalytic, systemic, cognitive and other explanatory models. All the theories stress the interaction between the subject and his/her environment, in particular when an initial psychotic episode emerges. In addition to their etiopathogenic interest, these models have the advantage of constituting specific therapeutic approaches, which indubitably increase the impact of treatment when associated with chemotherapy.

[Ballistic trauma resulting in carotid-cavernous fistula]. / Traumatisme balistique occasionnant une fistule carotido-caverneuse.

Post-traumatic carotid-cavernous fistula is an abnormal communication between the internal carotid artery in its intracavernous portion and the cavernous sinus, resulting from a tear in the arterial wall connecting the internal carotid artery with the cavernous sinus. Direct gunshot trauma is unusual. Clinically, the symptoms most often include a classic triad: red eye, chemosis and proptosis. Cross-sectional imaging including CT angiography allows for positive diagnosis by showing pathognomonic signs. Arteriography remains the procedure of choice for proper mapping of the lesion and accurate specification of the type of fistula, and at the same time serves as a means of embolization.
