Early Guillain-Barré Syndrome associated with acute dengue fever.

Various forms of neurological manifestations are reported in dengue fever. We describe here three cases of concomitant Guillain-Barré syndrome and dengue virus (DENV) infection during the largest DENV-1 outbreak in New Caledonia. Research of viral RNA was positive in both blood and CSF samples. All patients were treated with intravenous polyvalent immunoglobulins and recovered without sequelae within one week.

[Paraneoplastic limbic encephalitis associated with epidermoid lung carcinoma]. / Encéphalite limbique paraneoplasique et carcinome épidermoide du poumon.

Paraneoplastic limbic encephalitis is a rare clinical entity, most often associated with small cell lung cancer. We report a case of a 54-year-old man presenting status epilepticus, cognitive dysfunction and loss of short term memory associated with epidermoid lung carcinoma. CT scan was normal whereas MRI revealed hyperintensities on T2WI and FLAIR images in the temporolimbic regions. Treatment of the primary tumour was followed by neurological improvement.
