RESUMO
BACKGROUND: Coccidioidal meningitis is a life-threatening condition and a diagnostic challenge in cases of chronic meningitis. It is associated to severe complications, like basal arachnoiditis, hydrocephalus, and secondary vasculitis. OBJECTIVE: To present a 20-year retrospective clinical series of coccidioidal meningitis cases at a Mexican neurological referral center. RESULTS: The clinical records of 11 patients, predominantly males, were retrieved. Weight loss and night sweats were observed in 64 % of cases. Neurological signs included intracranial hypertension in 91 % of cases, altered alertness and meningeal syndrome in 72 %, and neuropsychiatric symptoms in 64 %. Mean CSF glucose levels were 30 ± 25 mg/dL, and pleocytosis ranged from 0 to 2218 cells/mm3. The diagnosis was confirmed by coccidioidal antigen latex agglutination in 91 % of cases. Radiological findings were hepatomegaly in 55 % of cases and pneumonia in 45 %. Neuroimaging findings included leptomeningitis in 73 % of cases, pachymeningitis in 45 %, and vascular involvement in 91 %. Less common findings included spinal cord lesion and mycotic aneurism, found in 18 % of cases. A molecular coccidioidal DNA test confirmed the predominance of Coccidioides immitis, detected in 64 % of cases. With respect to the clinical outcome, 46 % of patients died. The survivors suffered from sequels like chronic headache, cognitive alterations, and depression. CONCLUSIONS: Coccidioidal meningitis is an entity with high mortality rates. More than one half of patients suffered disseminated disease. Although meningeal signs are not frequent in chronic meningitis, more than two-thirds of our patients showed mild nuchal rigidity. In addition, cerebral and cerebellar volume loss, associated with cognitive impairment and depression, was often observed in surviving patients during the clinical-radiological follow-up.

OBJECTIVE: To describe the results of 10 years of nosocomial infection (NI) surveillance at a neurological center and evaluate the impact of control measures. PATIENTS AND METHODS: A descriptive and retrospective study was performed at a reference center for adult neurologic and neurosurgical patients located in Mexico City. Between 1990 and 2000, the number, site and type of NI were registered. Chi Square test was employed for statistical analysis of numerical data. RESULTS: Mean NI rate observed was 21 episodes per 100 discharges, with a 40% reduction during the period. Predominant NI were urinary tract infections (36%), lower respiratory tract infections (31%), phlebitis (9%), primary bacteremia (7%), surgical wound infections (7%), and pneumonia (4%). Control measures with a definite impact were organization of intravenous therapy teams with reduction in bacteremia (p = 0.009). Changes in preoperative care, hair clipping instead of shaving, clorhexidine shampoo, and technique of long tunneled ventriculostomy with a 57% reduction (p = 0.00006) in infections related with neurosurgical procedures. The increase in staff and equipment renewal of the respiratory therapy service decreased respiratory infections. CONCLUSIONS: The measures that reduced our NI rate may be useful in other centers for neurologic patients.
