The clinical features and the outcomes of eight cases of nosocomial Acinetobacter baumannii meningitis treated with ampicillin/sulbactam are reported. All the patients had fever, neck stiffness or meningeal signs, and a low consciousness level, and in their cerebrospinal fluid (CSF), pleocytosis, a low glucose level, and an elevated protein level were noted. For all CSF isolates of A. baumannii, the MIC of ampicillin/sulbactam was < or = 8/4 microg/mL. The MICs of sulbactam by microdilution in two cases were 4 microg/mL. All isolates were resistant to cefotaxime, ceftriaxone, ceftazidime, ureidopenicillins, ciprofloxacin, and gentamicin. Seven isolates were resistant to imipenem. A. baumannii was isolated from other samples in seven episodes. All patients were treated with ampicillin/sulbactam (seven with 2 g/l g every 6 hours and one with 2 g/l g every 8 hours). Six patients were cured and two patients died of meningitis. There were no side effects with the ampicillin/sulbactam treatment. In conclusion, ampicillin/sulbactam may be effective as therapy for meningitis caused by A. baumanii resistant to imipenem and other beta-lactam drugs.

A case of Leuconostoc cremoris bacteremia in a patient with burn wounds over 45% of the body surface is presented. Leuconostoc bacteremia has not previously been reported in burn patients. The predisposing factors in this case were severe burn wounds resulting in immunocompromise, presence of both intravenous and enteral feeding catheters, several surgical interventions and previous treatment with imipenem plus amikacin. The patient was successfully treated with ampicillin 2 g l.v. every 6 hours for 21 days. Infection with Leuconostoc should be suspected when vancomycin-resistant organisms resembling streptococci are isolated.

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, 35 (44.9%) had some neurological deficit, and only 27 (34.6%) had fever. Paravertebral, epidural, and psoas abscesses were detected in 73.1, 65.4, and 24.4% of the cases, respectively. Culture was positive in 48% of the percutaneous biopsies and in 61.7% of the open biopsies. After histological findings were included, the diagnostic yield of percutaneous biopsies was 68%. Fifty-five (70.5%) patients required surgical treatment at some stage of the disease. Although no deaths were directly attributable to tuberculous vertebral osteomyelitis and only 5.1% of patients relapsed, the mean overall hospital stay was 69.1+/-36.9 days, and 30 (38.5%) patients had severe functional sequelae. In conclusion, diagnosis of tuberculous vertebral osteomyelitis requires a high degree of suspicion. Percutaneous biopsy should be undertaken as soon as possible in any patient with compatible symptoms or radiological images in order to initiate suitable therapy.

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, who were diagnosed between 1983 and 1995 in two tertiary care centres. Of these patients, 105 (48%) had BVO, 72 (33%) PVO, and 42 (19%) TVO. RESULTS: One hundred and forty eight (67.6%) patients were male and 71 (32.4%) female. The mean (SD) age was 50.4 (16.4) years (range 14-84) and the mean (SD) duration of symptoms before the diagnosis was 14 (16.8) weeks. In 127 patients (57.9%) the vertebral level involved was lumbar, in 70 (31.9%) thoracic, and in 16 (7.3%) cervical. One hundred and nineteen patients (54.4%) received only medical treatment and 100 (45.6%) required both medical and surgical treatment. The presence of diabetes mellitus, intravenous drug abuse, underlying chronic debilitating diseases or immunosuppression, previous infections, preceding bacteraemia, recent vertebral surgery, leucocytosis, neutrophilia, and increased erythrocyte sedimentation rate (ESR) were significantly associated to PVO. A prolonged clinical course, thoracic segment involvement, absence of fever, presence of spinal deformity, neurological deficit, and paravertebral or epidural masses, were significantly more frequent in the group of TVO. The need for surgical treatment and the presence of severe functional sequelae were more frequent in the groups of PVO and TVO. CONCLUSION: There are significant clinical, biological, radiological, and prognostic differences between BVO, PVO, and TVO. These differences can point to the causal agent and orient the initial empirical medical treatment while awaiting a final microbiological diagnosis.

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 NPOS cases (P = .002). Neurological complications and inflammatory signs in the spine were more frequent with POS than with NPOS (P = .002 and P < .00001). Coagulase-negative Staphylococcus and anaerobic bacteria were more frequent in POS than in NPOS (P = .0001 and P = .05). Percutaneous bone biopsies yielded the etiology in 66.7% of cases, open bone biopsies in 100%, blood cultures in 55.6%, and cultures of adjacent foci in 94.4%. Eleven patients (35.5%) were cured with antimicrobial treatment, but surgical treatment was necessary in 64.5%. No relapses or deaths were recorded. Seventeen patients (54.8%) had severe functional sequelae, which were associated with inflammatory signs in the spine (P = .033), higher levels of leukocytosis (P = .05), higher erythrocyte sedimentation rates (P = .05), and paravertebral abscesses (P = .04).

BACKGROUND: Dirythromycin has several pharmacokinetic characteristics (long half life and high tissue concentrations) which suggest the possibility of administering shorter treatments than those conventionally used. The aim of this study was to determine and compare the efficacy of a 5 day treatment with dirythromycin once a day, versus diacetylmidecamycin twice a day over 7 days in the treatment of patients with acute bronchitis and acute exacerbations of chronic bronchitis. METHODS: A parallel, multicentric, randomized, double blind clinical study was carried out in 8 Spanish hospitals. RESULTS: One hundred seventy-four patients were included in the study, with 87 (80 evaluable) being randomly assigned to receive dirythromycin (500 mg/day over 5 days) and 87 (83 evaluable) diacetylmidecamycin (600 mg, twice daily over 7 days). A favorable symptomatic response (cure or improvement) was observed in 72/80 of the first group (90%) and in 74/83 (89.2%) of the second group. No statistically significant differences were found in the efficacy and safety between the two treatment groups in either the evaluable patients or on intention to treat analysis. CONCLUSIONS: The results of this study suggest that the administration of dirythromycin, once a day over 5 days, is as safe and effective as diacetylmidecamycin, twice a day over 7 days, in the treatment of acute bronchitis and acute exacerbations of chronic bronchitis.
