Magnetic Resonance Imaging of Parotid Gland Tumors: Dynamic Contrast-Enhanced Sequence Evaluation.

Objective: The aim of the study was to evaluate dynamic contrast-enhanced magnetic resonance (MR) imaging in the characterization of parotid gland tumors.

Methods: Fifty-five parotid lesions in 55 patients were retrospectively included. Two observers interpreted 2 reading protocols derived from all MR imaging in 2 distinct sessions, independently and blinded.

Stereotactic MRI in DYT1 dystonia: focal signal abnormalities in the basal ganglia do not contraindicate deep brain stimulation.

Aims: To study stereotactic magnetic resonance imaging (MRI) features of the basal ganglia in DYT1 primary dystonia.

Methods: Twenty-five genetically confirmed DYT1 dystonia patients (age range, 8-66 years; mean age, 22 years) underwent brain MRI under general anesthesia at the time of globus pallidus internus (GPi) deep brain stimulation (DBS) surgery. MR images were retrospectively reviewed for signal intensity alterations.

[Can multislice helical computed tomography replace conventional angiography in the diagnosis of non traumatic subarachnoid hemorrhage?].

Aim Of The Study: To evaluate the reliability of CT angiography in the diagnosis of non traumatic subarachnoid hemorrhage.

Materials And Methods: We prospectively studied 57 patients presenting with non traumatic subarachnoid hemorrhage. In all cases, CT angiography of the circle of Willis was performed, followed by conventional angiography.

[A collective malarial infestation during a humanitarian mission in west Africa].

Four truck drivers involved in a humanitarian mission across the Sahara towards Mali fell ill 15 days after their return. Plasmodium falciparum malaria (thankfully, non pernicious) was diagnosed with 3 to 4 days delay. The four drivers had been treated with chloroquine and proguanil but the dosage may have been insufficient with regard to their body weight (average weight = 110 kg).
