[Mumps meningitis: a case mix in a Neurology Department].
BACKGROUND
Parotiditis is a viral infection that produces a non-suppurative inflammation of the parotid glands, although it may affect other salivary glands, the testicles, meninges and the pancreas. Clinical meningitis appears in 1-10% of cases, normally between the 4th and the 10th day after infection of the parotid glands. In this study, we analyse the clinical and analytic characteristics of the patients admitted to our Neurology Department over the last 12 years.


METHODS
A retrospective study was conducted by analysing the hospital discharge reports. The eligibility criterion was the existence of an acute meningeal syndrome linked to the presence of positive IgM titres for the parotiditis virus. In all, 13 cases were found, with a mean age of 16.5 years, and most of them were males (92.3%). Parotiditis preceded meningitis in all our patients with an average of 8.3 days, while orchiepididymitis, when it occurred, appeared at the same time or after meningitis. Analysis of the cerebrospinal fluid showed a lymphocyte profile with glycorrhachia above 40%, except in two cases that showed a non-persistent neutrophilic profile. There was a transient 30.7% reduction in prothrombin time in the patients. No sequelae were observed.


CONCLUSIONS
Vaccination campaigns have drastically reduced the number of cases of meningitis due to this germ since the second half of the 90s. This virus must be borne in mind in cases of meningitis in young males who come from underdeveloped countries.
