Gelastic seizures and fever originating from a parietal cortical dysplasia.

Gelastic seizures (GS) is an uncommon seizure type characterized by sudden inappropriate attacks of uncontrolled and unmotivated laugh and its diagnostic criteria were elaborated by Gascon. These criteria included stereotypical recurrence of laugh, which is unjustified by the context, associated signs compatible with seizure, and ictal or interictal abnormalities. GS can be cryptogenic or symptomatic of a variety of cerebral lesions, the most common being hypothalamic hamartoma. However, GS associated with other types of cerebral lesions are exceedingly rare. The physiopathologic mechanisms of this type of seizure are still undefined. Two reports have described a non-lesional GS arising from a parietal focus. In this paper, we report the first case of lesional GS associated to the parietal area of the brain in a child and this case has associated fever that is likely an ictal symptom.

[Lemierre syndrome]. / Syndrome de Lemierre.

Lemierre's syndrome is a rare and severe condition, with a primary focus in the cervicofacial area and followed by thrombosis of the internal jugular vein and metastatic infections, most often pulmonary. The principal pathogen is Fusobacterium necrophorum. Less rare and associated with high mortality before antibiotics, Lemierre syndrome had became exceptional until the increase in the number of cases in recent years. Recovery is usually the rule, but often only after long convalescence and often surgical intervention. The reemergence of this disease calls for a review of the literature to update knowledge about its epidemiologic, clinical, and therapeutic aspects.

Lemierre syndrome: once seen it can never be mistaken.

Lemierre syndrome is a rare but severe septicaemia due most frequently to Fusobacterium necrophorum, with primary foci in the head, internal jugular vein thrombosis and metastatic infections, mainly in the lungs. We report two cases of Lemierre syndrome admitted to the paediatric unit of our hospital at 2-month intervals. The first was 10 years old and the second one was a 3-month-old infant. They were diagnosed on the 25th hospital day and at the time of admission, respectively. In the first case, diagnosis was delayed due to unfamiliarity with this disease. In the second patient the diagnosis was established on the first day because of the recent experience with patient 1. In both cases, bacteriological investigations were not helpful. Both patients had a favourable outcome after prolonged antibiotic treatment, anticoagulation and surgical drainage.
