Some data in the current medical literature suggests a link between medication overuse headache (MOH) and addictive behaviors. We present here a review of the clinical and biological data highlighting the role of addictive behaviors in MOH. ⋯ A pluridisciplinary approach is the only way to reduce the relapse rate which remains too high in MOH.

[Iatrogenic venous cerebral air embolism without pulmonary manifestation: A retrograde mechanism?].
Air embolism is a rare complication of various invasive medical procedures. Venous cerebral air embolism is usually the consequence of paradoxical embolism. We report a case of isolated cerebral air embolism resulting from a non-paradoxical mechanism. ⋯ In this case of venous cerebral air embolism, the lack of any cardiopulmonary manifestation, the lack of a patent foramen ovale and the neuroradiological findings are not in favor of the hypothesis of paradoxical embolism. The hypothesis of retrograde venous cerebral air embolism is discussed.

Neurological complications of infectious mononucleosis are rare. Various disorders have been described: meningitis, encephalitis, peripheral neuropathy. Isolated cranial nerve palsy has rarely been reported. ⋯ To the best of our knowledge, only seven cases of isolated palsy of the hypoglossal nerve complicating infectious mononucleosis have been previously reported.

It has been suggested that the H1N1 vaccine may be a trigger for the onset of narcolepsy-cataplexy, a rare disease whose autoimmune origin is suspected. ⋯ Although no formal link can be established, the unusual characteristics of the reported cases and the striking temporal relationship suggests that narcolepsy may be the result of an autoimmune reaction triggered by H1N1 vaccination in susceptible individuals.

Peripheral neuropathies sometimes complicate bariatric surgery. ⋯ The spectrum of peripheral neuropathies complicating bariatric surgery is wide, and includes pure small fiber neuropathy, axonal polyneuropathy, and demyelinating polyradiculoneuropathy. Treatment is mainly preventive, but sometimes surgical revision is needed.
