In an eight year period 16 cases of serious extrapulmonary Hemophilus influenzae infection in adults were identified, including cases of meningitis, pericarditis, epiglottitis, empyema, cellulitis, osteomyelitis, endometritis, urinary tract infection, orbital cellulitis, primary peritonitis, mesenteric lymphadenitis and aortic graft infection. An 18 month prospective study of H. influenzae infection in hospitalized adults identified 10 cases of bronchitis, 25 of pneumonia and 65 of respiratory tract colonization, but there were no extrapulmonary infections. In 29 percent of the respiratory tract infections, H. influenzae appeared to be a nosocomial pathogen; in 71 percent, the infection was mixed. Finally, 110 clinical isolates of H. influenzae were studied for antimicrobial susceptibility. Eight percent were ampicillin resistant, two strains were resistant to tetracycline and one to chloramphenicol, but all were susceptible to trimethoprim-sulfamethoxazole and cefamandole.

Six strains of ampicillin-resistant Haemophilus influenzae type b were studied in vitro for synergy between ampicillin and nafcillin. The minimal inhibitory concentrations for these strains with 10(4) colony-forming units per ml were 6.25 to 12.5 microgram of ampicillin per ml and 6.25 to 25 microgram of nafcillin per ml. Studies with these agents demonstrated synergism against all six strains of H. influenzae type b. Most strains were inhibited by 0.78 microgram of nafcillin plus 0.78 microgram of ampicillin per ml. A child with osteomyelitis caused by H. influenzae type b was successfully treated with a combination of ampicillin and nafcillin. These data suggest that further studies assessing the synergistic effect of this drug combination against H. influenzae type b are warranted.

Hemophilus influenzae may account for 10% or more of cases of acute hematogenous osteomyelitis in infants. H. influenzae osteomyelitis is more often seen in the upper extremities. Two patients with H. influenzae acute osteomyelitis seen at a community hospital are described. The second patient is the first known case of osteomyelitis secondary to ampicillin-resistant H. influenzae. A review of 22 additional cases revealed that meningitis accompanied osteomyelitis in 10% (2/22).

Cefamandole penetration was studied in 32 normal bone specimens. No antibiotic bone binding was found. Blood contamination of bone samples was measured by the haemoglobin method. Mean corrected levels attained (5.8 micrograms/g) exceed MIC values of sensitive Staphylococcus aureus, Haemophilus influenzae and Enterobacteriaceae. Similar diffusion was observed in cortical and trabecular bone. The results obtained invite further studies on preoperative prophylaxis and treatment of osteomyelitis.

Acute sinusitis is one of the most commonly observed entities in clinical practice. Despite the frequency of the disease, diagnosis and therapy often remain empiric. Most cases are secondary to sinus ostia obstruction associated with the common cold or allergies. Maxillary sinusitis is most common. Because of the proximity of vital anatomic structures and venous drainage systems, serious complications frequently arise from sphenoid, frontal, and ethmoid sinusitis. Clinical signs and symptoms most helpful in the diagnosis of maxillary sinusitis are the presence of a maxillary toothache, lack of improvement with decongestants, a purulent nasal discharge, cough, purulent secretions observed on nasal examination, abnormal transillumination, and sinus tenderness. Plain film radiographs are helpful, but do not adequately visualize the anterior ethmoid sinuses. Computed tomography provides superior visualization, but cost remains prohibitive for routine cases. Most maxillary sinusitis in adults is secondary to Streptococcus pneumoniae or Hemophilus influenzae. Moroxella catarrhalis is common in children. Staphylococcus aureus is observed more frequently in frontal or sphenoid disease. Most patients with acute sinusitis are treated without microbiological diagnosis and respond well to commonly used oral antimicrobials with activity against the usual pathogens. Complications of sinusitis include meningitis, periorbital infections, subdural empyema, epidural abscess, brains abscess, cavernous sinus thrombosis, and osteomyelitis.

Biapenem (L-627) was evaluated for its safety and efficacy in 27 children with various bacterial infections. L-627 was effective in cases with osteomyelitis due to Staphylococcus aureus, pneumonia and purulent meningitis due to penicillin-resistant Streptococcus pneumoniae, and urinary tract infections due to Enterococcus faecalis, Escherichia coli, or Pseudomonas aeruginosa. However, L-627 failed to produce good responses in 2 of 7 cases of Haemophilus influenzae infections. Pharmacokinetic parameters of 30-minutes infusion of 12 mg/kg were as follows: Cmax 29-46 micrograms/ml, T 1/2 0.68-0.94 hr. Adverse reactions were minimal. These data suggest that L-627 is safe in children, and is valuable especially for treatment of infections in immunocompromised hosts and infections due to multiply resistant bacteria.

Two hundred forty-one children who had osteomyelitis during a 19-year period, 1974 through 1992, were identified by chart review. Acute osteomyelitis or chronic osteomyelitis was the diagnosis for 221 (92%) and 20 (8%) of the children, respectively. Bacteriologic etiology was documented in 137 (57%) of the cases. Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella species organisms, and Haemophilus influenzae type b were isolated from 97 (40%), 10 (4%), 8 (3%), and 7 (3%) of the children, respectively. S. aureus was the predominant microorganism in all age groups, whereas H. influenzae occurred only in children younger than 2 years of age. P. aeruginosa was recovered predominantly from children with a penetrating injury of the foot, while salmonella bone infections were diagnosed in patients with sickle cell disease. These data provide guidelines for the initial work-up for and management of osteomyelitis in children living in developing Latin American countries.

Cefepime, a novel, injectable alpha-methoxyimino aminothiazolyl cephalosporin, is active in vitro against many of the Gram-positive and Gram-negative bacteria which cause severe infections, including Pseudomonas aeruginosa. It is more active than existing third-generation cephalosporins against multiply-resistant strains of Enterobacteriaceae because of its low affinity for beta-lactamases and its resistance to hydrolysis by these enzymes. Cefepime retains its high potency of activity against methicillin-susceptible Staphylococcus aureus, coagulase-negative staphylococci and streptococci other than enterococci. Seventy-four patients (46 male and 28 female) were treated with cefepime 2 g i.v. every 12 h; 61 patients were evaluable for efficacy (39 male and 22 female). The infections included pneumonia caused by Gram-negative bacilli (21 patients, six with bacteraemia), septicaemia (seven), pyelonephritis (two), osteomyelitis (23, mainly caused by S. aureus), septic arthritis (four) and soft tissue infections (four, one with bacteraemia). Responses were as follows: 52 (85.3%) patients cured; three (4.9%) improved and six (9.8%) failed. The failures included three patients with osteomyelitis, one with pyelonephritis and two with pneumonia. The pathogens and eradication rates were: S. aureus 23/24 (96%), Staphylococcus epidermidis 4/4, Streptococcus spp. 10/10 (100%), P. aeruginosa 11/14 (79%), Enterobacteriaceae 28/28 (100%), Haemophilus spp. 3/3 and others 7/7. Clinical adverse effects included diarrhoea in 11 patients (14.9%) nausea in five (6.8%) and pruritus in three (4.1%). Laboratory abnormalities included leucopenia in three patients (4.1%) and direct Coombs' conversion in 32 (43.2%). Patients were treated for an average of 31.8 days for osteomyelitis and 11.9 days for other infections.(ABSTRACT TRUNCATED AT 250 WORDS)

Cefepime is a novel methoxyimino-aminothiazolyl cephalosporin with a quaternized N-methyl-pyrrolidine moiety at the 3' position conferring zwitterionic properties. Because of this the molecule penetrates the outer cell membrane of Gram-negative bacteria rapidly. In addition it is resistant to degradation by several plasmid and chromosomally-mediated beta-lactamases, for which it also shows very low affinity and no inducing capacity. It has good affinity for PBPs 2 and 3 of Escherichia coli and for PBP 3 of Pseudomonas aeruginosa. Its broad-spectrum of activity includes Gram-positive and Gram-negative pathogens. It is more active than cefotaxime or ceftazidime, against Enterobacteriaceae. The MIC90 for P. aeruginosa is higher than that of ceftazidime, but lower than those of cefpirome, cefoperazone and latamoxef. Other Gram-negative organisms, Haemophilus influenzae, Neiserria meningitidis, Neiserria gonorrhoeae, Moraxella catarrhalis are highly susceptible to cefepime. Among Gram-positive species methicillin-susceptible Staphylococcus aureus and coagulase-negative staphylococci, whether beta-lactamase producers or not, Streptococcus pneumoniae and Streptococcus pyogenes are susceptible. Cefepime is active against cefotaxime- and/or ceftazidime-resistant Enterobacteriaceae. Only strains of P. aeruginosa producing large amounts of beta-lactamase may be resistant to both ceftazidime and cefepime. In experimental infections such as meningitis, induced with various bacterial species in neonatal rats and chronic staphylococcal osteomyelitis in rabbits, cefepime has shown good efficacy.
