The use of external ventriculostomy at our institution has been retrospectively analyzed to determine the incidence of cerebrospinal fluid sepsis. Placement of 65 ventriculostomies over a 2-year period resulted in three cases of complicating meningitis and ventriculitis (4.5%). Duration of ventriculostomy placement did not seem related to the rate of infection but the method of placement, the prophylactic antibiotics used, and the monitoring and collecting system employed may be important.

The rat brain abscess model provides a substrate for the modeling of delivery of therapeutic agents to intracerebral mass lesions. We now report refinement of the Escherichia coli brain abscess model in rat. A K1 surface antigen-negative E. coli isolated from human blood culture was stereotaxically inoculated into deep brain sites. Histopathologic analyses and quantitative cultures demonstrated the consistent production of lesions. No animal in this consecutive series developed meningitis, ventriculitis or sepsis. By contrast, prior experience with E. coli abscess production resulted in 25% failure rate of abscess production or death from sepsis. This improvement in the model may be attributable to specific characteristics of the bacteria used, modification of the inoculation method or the intracerebral placement technique. The present work suggests a reliable and consistent brain abscess model, which may be further used to study brain suppuration.

Cryptosporidiosis was diagnosed in 4 cockatoos with psittacine beak and feather disease. Three of the birds had cryptosporidiosis confined to the epithelium covering the bursa of Fabricius. One bird had generalized parasitism of the small intestine, large intestine, and bursal epithelium. All of the birds had intermittent to protracted diarrhea before death. Presumably, acquired immunodeficiency from psittacine beak and feather disease promoted establishment of cryptosporidiosis and other secondary diseases including septicemia, peritonitis, chlamydiosis, and mycotic ventriculitis.

Recent reports have implicated Enterobacter sakazakii, a gram-negative enteric bacillus, in neonatal sepsis and meningitis. Cases of severe central nervous system involvement, including ventriculitis, brain abscess, infarction, and cyst formation, have been described. We present serial head CT findings in a case of neonatal E. sakazakii meningitis complicated by a ring enhancing cerebral infarction which mimicked abscess formation. In meningitis secondary to this agent, a recognized pattern of cerebral hypodensity with or without cystic degeneration late in the course of the infection is likely to represent cerebral infarction rather than an abscess especially if there is a lack of culture evidence of a bacterial infection.

There exists high incidence of bacteremia, sepsis and meningitis in young infants with Salmonella infection. However, focal intracranial abscesses due to Salmonella infections are rare. We reported a 2-month-old male baby presenting salmonella infection with brain abscess and purpura fulminans. The patient's clinical course was fulminant. He was admitted due to fever, irritability, anemia and leukopenia. He developed cardiac arrest, shock and skin diathesis on his second hospitalization day. After resuscitation he became comatous and showed acrocyanosis and gangrenous skin over the hands, feet and left ear lobe. Both blood and cerebrospinal fluid cultures were Salmonella Group B. The patient got worse rapidly in spite of vigorous treatment. Subdural empyema, ventriculitis and later brain abscess were detected by serial brain sonograms. He died of central nervous system failure, gastrointestinal bleeding and renal failure on the eighteenth hospitalization day.

We used single daily intravenous teicoplanin as therapy for 12 severe nosocomial infections caused by gram-positive bacteria. A daily dosage of 3-6 mg/kg was usually adopted; however, in selected cases the dosage was increased to 8-9.5 mg/day on the basis of serum bactericidal monitoring. Most of these infections were life-threatening and included ventriculitis/meningitis (3 cases), sepsis (3 cases), mediastinitis (1 case) and extensive burn wound infection (1 case). Staphylococcus aureus was by far the most frequent pathogen and methicillin-resistant strains were isolated in 7 out of 9 infections caused by this organism. The remaining isolates were Staphylococcus epidermidis, JK Corynebacterium, Streptococcus agalactiae and Propionilbacterium acnes. Additional antibiotics were used in 5 cases for concomitant gram-negative bacillus etiology (2 cases), granulocytopenia (2 cases), superinfection (1 case). Overall a clinical success and microbial eradication were documented in 100% and 91% of 12 cases, respectively. Except one case of fever, no other major adverse effect was observed and no patient required trial therapy discontinuation. In conclusion, our preliminary data seem to suggest a satisfactory activity of teicoplanin against nosocomial gram-positive infections.

Between January of 1983 and December 1984, 11 strains of pneumococci resistant to penicillin were isolated, from a total of 46 strains studied with clinical signification, thus accounting for 23.9%. In nine cases (19.5%) pneumococci showed partial resistance to penicillin and in two strains (4.3%) resistance was total. Pneumococcal disease in our 11 patients was demonstrated by blood culture in 7 cases and by culture of the CSF, in 4. Diagnosis of the patients were as follows: 4 sepsis in immunosuppressed host, 2 bacteremia without an evident focus, 1 pneumonia, 3 meningitis and 1 ventriculitis. Vancomycin and rifampin are the most active in this cases. Some of the new cephalosporins of the third generation (cefotaxime and ceftriaxone) and cefuroxime have a good activity in vitro and a good passage to the CSF.

Ceftriaxone has a very long serum half-life and enhanced in vitro activity against common pediatric pathogens. Therefore we evaluated the efficacy and safety of once daily ceftriaxone therapy in 57 children with serious infections including: meningitis (26 patients); ventriculitis (3); pyelonephritis (7); osteomyelitis (6); abscess (4); septic arthritis (3); sepsis (2); and miscellaneous infections (6). The most common isolates were Haemophilus influenzae (23), Escherichia coli (9) and Staphylococcus aureus (8). Ceftriaxone was given intravenously or intramuscularly in a dose of 50 mg/kg for non-central nervous system (CNS) infections. Patients with CNS infections received an initial dose of 100 mg/kg followed by 80 mg/kg 12 hours later and once daily thereafter. In a limited number of patients no major differences in serum ceftriaxone concentrations were found after intravenous or intramuscular injection. Of 57 patients with pathogens isolated 55 were completely cured; in one patient with Klebsiella pneumoniae ventriculitis, intraventricular gentamicin was briefly added to the regimen. Another patient with an anaerobic liver abscess recovered after metronidazole was administered. In three patients a delayed response to ceftriaxone was noted. One patient with previous recurrent infections had a second episode of H. influenzae meningitis 22 days after cessation of therapy. Clinical side effects were noted in 10 of 71 patients (including 14 treated patients who had negative cultures). Seven patients had diarrhea, one each had fever or rash and one had fever, rash and arthralgia. Laboratory side effects in 16 of 71 patients included eosinophilia (7), thrombocytosis (7), elevated liver enzymes (4) and leukopenia and neutropenia (2).(ABSTRACT TRUNCATED AT 250 WORDS)

Cefmenoxime, an investigational semisynthetic cephalosporin, was evaluated in 18 pediatric patients with a variety of infections. There were seven patients with urinary tract infections, two with wound infections, two with osteomyelitis, two with abscess infections, one with cervical adenitis, one with hidradenitis, one with pneumonia and sepsis, one with periorbital cellulitis, and one with ventriculitis. A total of 16 (88%) patients had a satisfactory clinical response demonstrated by improvement in clinical signs and symptoms. A total of 12 (67%) patients demonstrated eradication of their infecting organisms. Of the pathogens isolated in these patients, 16 isolates were susceptible to cefmenoxime. One patient developed a generalized urticarial rash that resolved within 24 h after cessation of cefmenoxime therapy. Mean peak level in serum after intravenous infusion was 55 micrograms/ml.

Because of increased aminoglycoside resistance of hospital bacterial isolates, aminoglycoside sensitivity patterns of isolates in a large children's hospital were assessed before and during a 33-month period of almost exclusive amikacin use. There was no significant change in overall resistance rates of gram-negative enteric bacteria to gentamicin (4.8 percent and 4.6 percent), tobramycin (2.5 percent and 3.6 percent), and amikacin (1.2 percent and 1.8 percent) from the pre-amikacin period to the amikacin usage period, respectively. No significant differences were observed for isolates of Escherichia coli, Klebsiella, Serratia, Acinetobacter, and Pseudomonas species. In contrast, significant decreases in gentamicin and tobramycin resistance rates for Enterobacter, Citrobacter, and Pseudomonas aeruginosa and in gentamicin resistance of Proteus were found. Very little change in resistance of staphylococcal isolates was seen during a shorter evaluation period. Pediatric aminoglycoside usage includes therapy of neonatal infections, cystic fibrosis, febrile neutropenic episodes in patients with cancer, abdominal surgery, bacterial endocarditis, and gram-negative central nervous system infections. Amikacin has also been used successfully as single-dose therapy of urinary tract infections, and acceptable cerebrospinal fluid levels of amikacin have been documented in hydrocephalic patients with ventriculitis. In vitro studies of 22 bacterial isolates demonstrated synergy between amikacin and penicillin or newer cephalosporins in 13, an additive effect in seven and indifference in two. No antagonism was found. In addition, in vivo synergy between imipenem and amikacin was found in neutropenic infant rats with P. aeruginosa sepsis using a strain with which no synergy was demonstrable in vitro. Amikacin is effective in pediatric infections and is well tolerated by children. Because excessive or inadequate levels are frequent with usually recommended doses, particularly in neonates and patients with compromised renal function or cystic fibrosis, serum levels should be monitored to minimize risk and to ensure therapeutic levels.
