RESUMEN
Our objective was to describe incidence, clinical, radiographic and microbiological features of bacteremic pneumococcal pneumonia (BPP) in our environment. A total of 101 patients (7 were treated as outpatients), older than 18 years of age suffering BPP were prospectively evaluated. The incidence was 2.8 cases per 1000 admissions, 50 were males, mean age was 59.9 years (19-97), mortality was 11.8%. Eighty three percent of fatalities occurred within 3 days of admission. Mortality rate increased with advancing age. Fever, cough and chest pain were the commonest presenting symptoms and 44% of patients had extrapulmonary manifestations. Cigarette smoking, chronic obstructive lung disease, alcoholism and congestive heart failure (CHF) were the commonest underlying conditions. CHF was more frequent in non-survivors (p = 0.002). A lobar pattern at chest radiograph predominated in survivors and a diffuse pattern in non-survivors (p = 0.007). Pleural effusion (20.7%), empyema (7.9%) and respiratory failure (7.9%) were the main complications. Underlying diseases were present in 100% of non-survivors (p = 0.03). Ninety four percent of patients were treated with beta-lactam antibiotics. Streptococcus pneumoniae was isolated from sputum in 6 cases. Three out of 101 S. pneumoniae isolates recovered from blood samples (one from each patient) presented organisms resistant to penicillin. We observed an incidence of BPP that is similar to the observed in other countries. There are clinical and radiographic differences between survivors and non-survivors. Penicillin-resistant S. pneumoniae is still an unusual problem in our area

Enterococcus faecalis meningitis is an infrequent entity that accounts for less than 1 percent of all suppurative meningitis in the adult. Usually, this infection affects patients with compromised host defenses or those who have congenital or acquired CNS lesions mainly as intrahospitalary infections. An 85 year old woman from our community (Tandil county) without any predisposed condition, was admitted in the hospital in an unconscious state (grade 3 Glasgow's index), meningeal signs and purulent CSF, from which E. faecalis was isolated. The patient was treated with IV Ampicillin and Gentamycin (17 days), intrathecal Gentamycin (4 days) and ]V dexametasona (6 days). The clinical and bacteriological remission was achieved, without any sequel or relapse during 2 years follow up.
