Analysis of Fourteen New Cases of Meningovascular Syphilis: Renewed Interest in an Old Problem.

Neurosyphilis (NS) remains a public health problem. Several recent reports suggest a worldwide increase in the incidence of this condition. Various syndromes can occur in NS, such as syphilitic meningitis, meningovascular syphilis, parenchymatous and gummatous neurosyphilis.

A Specific Diplotype H1j/H2 of the MAPT Gene Could Be Responsible for Parkinson's Disease with Dementia.

Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer disease. Five to ten percent of patients have monogenic form of the disease, while most of sporadic PD cases are caused by the combination of genetic and environmental factors. Microtubule-associated protein tau (MAPT) has been appointed as one of the most important risk factors for several neurodegenerative diseases including PD.

Status epilepticus revealing syphilitic meningoencephalitis.

The incidence of seizures in neurosyphilis ranges from 14 to 60%, however, neurosyphillis presenting with status epilepticus (SE) is rare. We report the case of a 49 year old man with no history of epilepsy and with a 9-year history of untreated syphilitic chancre. He presented in October 2005 with four stereotyped epileptic seizures lasting less than 2 minutes followed by a prolonged seizure lasting 20 minutes without recovery of consciousness.
