The number of nosocomial infections caused by Acinetobacter baumannii has increased in recent years. During a 12-month study, there were 1.8 episodes of A. Baumannii bacteremia per 1,000 adults admitted to a hospital in Seville, Spain. Seventy-nine patients were included in the study. A. baumannii bacteremia occurred after a mean (+/- SD) hospitalization of(More)
OBJECTIVES To describe a large series of patients with vertebral osteomyelitis (VO), and to compare the clinical, biological, radiological, and prognostic features of pyogenic (PVO), tuberculous (TVO), and brucellar vertebral osteomyelitis (BVO). METHODS A retrospective multicentre study, which included 219 adult patients with VO with confirmed aetiology,(More)
BACKGROUND Fever of intermediate duration (FID), characterized by a febrile syndrome lasting from 7 to 28 days, is a frequent condition in clinical practice, but its epidemiological and etiologic features are not well described. Murine typhus (MT) is a worldwide illness; nevertheless, to our knowledge, no studies describing its epidemiological and clinical(More)
Described here is a case of meningitis caused by multidrug-resistant Acinetobacter baumannii susceptible only to colistin, which was treated successfully with intravenous colistin sulfomethate sodium (5 mg/kg/day). The levels of colistin in serum and cerebrospinal fluid and the pharmacokinetic/pharmacodynamic parameters of colistin were determined. In this(More)
OBJECTIVE To evaluate the pharmacokinetic interactions between efavirenz and rifampicin (rifampin) in patients with HIV infection and tuberculosis. DESIGN Nonblind, randomised, pharmacokinetic study. PATIENTS 24 patients (21 male, 3 female; mean age 37 years) with HIV infection and tuberculosis. INTERVENTIONS Patients were randomised to one of the(More)
The frequency of community-acquired pneumonia coupled with its mortality rate of 10 to 25% is of growing concern to clinicians. A prospective study of 67 patients with severe community-acquired pneumonia was carried out to determine the causative agents, the impact fore-knowledge of the etiology has on the outcome, the value of clinical and radiologic(More)
We studied 31 cases of postoperative pyogenic spondylodiskitis (POS), comparing them with 72 cases of nonpostoperative pyogenic spondylodiskitis (NPOS). POS represents 30.1% of cases of pyogenic spondylodiskitis. The onset of symptoms occurred an average (+/-SD) of 27.7 (+/- 25.3) days following surgery. Predisposing factors were less frequent in POS than(More)
In order to determine the clinical features and current prognosis of tuberculous vertebral osteomyelitis, the charts of all patients diagnosed with definite or probable tuberculous vertebral osteomyelitis from January 1983 to June 2002 (n=78) were reviewed. The mean delay to diagnosis was 6.1 months. Sixty-five (83.3%) patients had inflammatory spinal pain,(More)
Acinetobacter baumannii has successfully developed resistance against all common antibiotics, including colistin (polymyxin E), the last universally active drug against this pathogen. The possible widespread distribution of colistin-resistant A. baumannii strains may create an alarming clinical situation. In a previous work, we reported differences in(More)
Acinetobacter baumannii has emerged as a medically important pathogen because of the increasing number of infections produced by this organism over the preceding three decades and the global spread of strains with resistance to multiple antibiotic classes. In spite of its clinical relevance, until recently, there have been few studies addressing the factors(More)
