11/94. bacillus cereus brain abscesses occurring in a severely neutropenic patient: successful treatment with antimicrobial agents, granulocyte colony-stimulating factor and surgical drainage.

    Multiple brain and liver abscesses developed immediately after bacillus cereus bacteremia in a neutropenic patient with acute lymphoblastic leukemia. After even 8 weeks of antimicrobial chemotherapy together with administration of granulocyte colony-stimulating factor, every infectious process disappeared but the patient's headache has still persisted. Because the wall of one brain abscess became thin and was in danger of rupturing into the ventricle, surgical drainage was performed, resulting in disappearance of headache and resolution of brain abscess. The present case indicates that a combined medical and surgical approach is mandatory to treat patients with brain abscesses.

12/94. Focal intracranial infections due to propionibacterium acnes: report of three cases.

    OBJECTIVE AND IMPORTANCE: Except for its role in shunt infections, propionibacterium acnes has been of little interest to neurosurgeons. The rarity and indolent nature of focal intracranial infections by P. acnes limit their recognition. Three cases of serious intracranial infection due to this organism are described. CLINCAL PRESENTATION: Three patients with histories of immunosuppression and neurosurgical procedures developed nonspecific, delayed presentations (5 wk to 5 yr after surgery) of intracranial infections. In two patients, radiological investigations showed enhancing lesions that were later found to be brain abscesses. A subdural empyema was found in the third patient. INTERVENTION: All three patients underwent surgical drainage of the purulent collections. P. acnes was isolated in each case, and each patient was treated with a 6-week course of intravenous penicillin. All three patients made good recoveries, and subsequent imaging showed no recurrence of the infectious collections. CONCLUSION: P. acnes is an indolent organism that may rarely cause severe intracranial infections. This organism should be suspected when an intracranial purulent collection is discovered in a patient with a history of neurosurgical procedures. Immunosuppressed patients may be susceptible to this otherwise benign organism. Surgical drainage and treatment with intravenous penicillin should be considered standard therapy.

13/94. Clinical experience with linezolid in the treatment of resistant gram-positive infections.

    This study presents our clinical experience with linezolid in 19 patients with serious resistant gram-positive infections enrolled as part of the compassionate study. In this prospective, non-randomized, noncomparative study, 19 patients were enrolled as part of the National Compassionate Study Protocol conducted by Pharmacia-Upjohn. At the time of this writing, these patients had not been published in the literature. All of the patients had to have documented evidence of serious gram-positive infections in normally sterile sites and should have been unable to tolerate available antimicrobial therapy or be unresponsive to available drugs. Clinical characteristics, laboratory values, and pharmacokinetic and pharmacodynamic parameters were obtained. patients were followed both short-term and long-term after completion of therapy. Nineteen patients were enrolled: 13 females and 6 males. The average age was 63 years. The average length of therapy with linezolid was 22 days. methicillin-resistant staphylococcus aureus (MRSA) was treated in eight patients, methicillin-resistant staphylococcus epidermidis (MRSE) in two patients, vancomycin-resistant enterococcus faecium (VREF) in eight patients, and coagulase-negative Staphylococcus in two patients. Co-infecting organisms include Enterococcus species colonization in six patients, pseudomonas species in one patient, serratia marcenens in one patient, and candida albicans in one patient. Sterile sites that were infected included bone and joint (wounds and septic joints) in six patients, gastrointestinal system (hepatobiliary, liver abscess, Crohn's) in five patients, genitourinary (kidney and urine) in two patients, blood in five patients, respiratory in one patient, and aortic valve in 1 patient. Linezolid was given at 600 mg IV every 12 hours with a mean length of therapy of 22 days. Surgical drainage was used in combination with linezolid in 11 of the patients. Seventy nine percent of these patients achieved clinical and microbiologic cure, and none of the deaths reported in this series were related to the drug. Adverse events included skin rash in one patient, mild bone marrow suppression in two patients, and mild elevation in liver function tests in two patients. No life-threatening adverse events were noted. It appears that linezolid, along with surgical intervention (when necessary), appears to be an effective treatment option for resistant gram-positive infections. Long-term studies evaluating the possible resistance rates are necessary.

15/94. Intracranial abscess as a complication of subperiosteal abscess of the orbit.

    PURPOSE: To describe the potential complication of intracranial abscess in the setting of orbital abscess. methods: We retrospectively reviewed case reports and the literature. Three patients were found to have pansinusitis progressing to subperiosteal abscess of the orbit and subsequent intracranial abscess. RESULTS: Three patients, ages 14, 26, and 57 years, with concurrent pansinusitis, subperiosteal abscess of the orbit, and intracranial abscess were treated with intravenous antibiotics and surgical drainage of the orbital abscess and sinuses. Two of the three patients required drainage of the intracranial abscess. CONCLUSIONS: Although rare, intracranial abscess is a life-threatening complication of orbital abscess. It requires aggressive intervention by a multidisciplinary team.

16/94. Necrotizing fasciitis secondary to peritonsillar abscess: a new case and review of eight earlier cases.

    Necrotizing fasciitis is a potentially fatal soft-tissue infection that occurs only rarely in the head and neck region. Broad-spectrum parenteral antibiotics and surgical debridement are the mainstays of treatment. Until now, only eight cases of necrotizing fasciitis secondary to peritonsillar abscess have been described in the English-language literature. In this article, we report a new case that occurred in an otherwise healthy 43-year-old woman. In addition to standard treatment, the patient underwent a hot tonsillectomy. After 23 months of follow-up, she is in good health.

17/94. Rapidly expanding lung abscess caused by legionella pneumophila in immunocompromised patients: a report of two cases.

    We describe two cases of lung abscess caused by legionella pneumophila in immunocompromised patients. The first case had been treated initially with 60 mg prednisolone for ulcerative colitis, and L. pneumophila serogroup 1 was isolated from sputum samples after cavitation of the lung lesion. The second case was diagnosed as plasma cell lymphoma at post-mortem examination. L. pneumophila serogroup 5 was isolated from the contents of lung abscess, together with enterococcus faecium and prevotella intermedia in the post-mortem examination. lung abscess caused by Legionella is unusual. Here, we discuss the difficulty of diagnosis of legionellosis in patients with unusual chest radiographic findings.

18/94. Acute suppurative thyroiditis caused by an infected piriform sinus fistula with thyrotoxicosis.

    We report herein an unusual case of thyrotoxicosis caused by acute suppurative thyroiditis (AST) infected through a piriform sinus fistula (PSF). A 28-year-old man presented with pain over the thyroid gland and elevated serum thyroid hormone levels, a picture similar to subacute thyroiditis. A fine-needle aspiration biopsy from the left lobe showed neutrophil infiltration, and culture from the aspirate grew anaerobic peptostreptococcus. A neck computed tomography (CT) scan showed an abscess in the thyroid gland, and barium swallow revealed the presence of PSF. Appropriate antibiotic treatment ameliorated his symptoms of infection, followed by normalization of thyroid function. Three months later, he underwent fistulectomy and partial left lobectomy. The end of the PSF track was found in the left thyroid lobe. Thus infection of the thyroid gland through the infected PSF was likely the cause of supprative thyroiditis. The unusual clinical features of AST in this patient include the presence of severe thyrotoxicosis, relatively late onset (28-years-old) of infection despite the presence of congenital PSF, and the lack of acute inflammatory signs on the overlying skin of the thyroid gland. It is important to recognize this type of AST, since fistulectomy is required to prevent recurrent AST.

19/94. Three cases of Rothia dentocariosa bacteraemia: frequency in denmark and a review.

    Three cases of non-endocarditis-associated Rothia dentocariosa bacteraermia occurred in Viborg County within the space of a year, whereas no cases have been registered in other parts of denmark during the last 10 y. Two patients wore dentures but had no history of oral infection, while in the last patient a tooth abscess was detected on examination. R. dentocariosa is a common inhabitant of the oral cavity and the causative agent of a wide spectrum of infectious symptoms. It is only rarely identified in blood cultures, possibly due the inadequacy of the available identification methods.

20/94. liver abscess formation after microwave coagulation therapy applied for hepatic metastases from surgically excised bile duct cancer: report of a case.

    We report the case of a liver abscess associated with microwave coagulation therapy (MCT). A 67-year-old man underwent a pylorus-preserving pancreatoduodenectomy for bile duct cancer in August 1998. In June 1999, abdominal computed tomography (CT) showed three low-density areas in his liver. With a diagnosis of multiple metastatic liver tumors, we applied MCT to each liver tumor. The patient presented with fever after therapy. Abdominal CT showed a hepatic abscess, which was treated by percutaneous transhepatic abscess drainage under ultrasonography. A bacteriological examination of the pus material revealed the presence of enterococcus faecalis and candida albicans. Treatment resulted in a rapid resolution of symptoms. Our case indicated that care should be exercised in using MCT for the treatment of liver tumors in patients who have undergone reconstructive surgery of the biliary tract.
