Cefpirome (HR 810, CPR), a new cephem antibiotic, was investigated for its experimental and clinical studies in pediatrics. The results obtained are summarized as follows. 1. Plasma and urinary levels of CPR were determined in 2 children (age 5 and 7 years) after the one shot intravenous injection of the drug at 20 mg/kg. Average plasma levels of the drug were 44.7 micrograms/ml, 28.5 micrograms/ml, 10.5 micrograms/ml, 4.6 micrograms/ml and 1.5 micrograms/ml at 1/2 hour, 1 hour, 2 hours, 4 hours and 6 hours, respectively, and the average half life was 1.57 hours. Average urinary levels of the drug were 1,785 micrograms/ml, 545 micrograms/ml and 198 micrograms/ml at 0-2 hours, 2-4 hours, 4-6 hours, respectively and the average urinary elimination rate was 52.0%. The results were nearly equivalent to those in adults except for urinary elimination rate which tended to be slightly lower than that in adults. 2. Cerebrospinal fluid levels in 3 cases of purulent meningitis treated with CPR were investigated. Cerebrospinal fluid levels in a case of Neisseria meningitidis were 11.5-23.1 micrograms/ml at 1 hour and 0.94 microgram/ml at 5 hours after intravenous injection of 44.4 mg/kg, 4 times a day. Cerebrospinal fluid levels in a case of Streptococcus pneumoniae were 1.01-4.23 micrograms/ml at 1 hour after intravenous injection of 49.0 mg/kg, 6 times a day, and in the other case with Streptococcus pneumoniae, the levels were 16.8-37.1 micrograms/ml at 1 hour, 11.3 and 3.60 micrograms/ml at 3 and 4 hours after intravenous injection 52.2 mg/kg, 6 times a day. These results are not inferior to those with cefotaxime or ceftriaxone. These levels appear to be higher than MIC90 values against Escherichia coli, Streptococcus agalactiae, S. pneumoniae or Haemophilus influenzae which are the major pathogens of these diseases. 3. CPR was given to 62 patients and clinical efficacy, bacteriological response and adverse reactions were evaluated. Evaluated cases for clinical efficacy included 3 cases of purulent meningitis, 1 case of acute purulent otitis media, 2 cases of acute purulent tonsillitis, 1 case of acute bronchitis, 49 cases of acute pneumoniae, 1 case of scarlet fever, 1 case of acute osteomyelitis, 1 case of acute enterocolitis, and 2 cases of acute UTI, totalling 61 cases. Clinical efficacies were excellent in 38 cases, good in 22 cases and fair in 1 case with an efficacy rete of 98.4% (excellent + good).(ABSTRACT TRUNCATED AT 400 WORDS)

One hundred thirty-five children with acute osteomyelitis were identified by chart review during a 7-year period, January 1, 1980, through December 31, 1986. Bacteriologic causes were detected in 75 (55%) of the patients. Staphylococcus aureus, Haemophilus influenzae type b, and Pseudomonas aeruginosa were identified in 34 (25%), 16 (12%), and eight (6%) children, respectively. Staphylococcus aureus occurred in all age groups, H influenzae type b occurred only in children younger than 3 years and was the number one cause of disease in this group. Pseudomonas aeruginosa occurred exclusively in children older than 9 years. Children with H influenzae type b had clinical and laboratory findings that were almost indistinguishable from a matched group of children with osteomyelitis due to other known bacteria, although children with H influenzae type b tended to have more joint effusions (63% vs 27%), less lower extremity disease (22% vs 70%), and fewer positive cultures from bone or joint aspirates (41% vs 89%). Unlike most pediatric cases of osteomyelitis, the ones due to P aeruginosa did not represent the hematogenous route of infection; penetrating injury to the foot was present in every case. Children with P aeruginosa infections were older than 9 years (100%), predominantly male (88%), often afebrile (83%), and never bacteremic. These data provide guidelines for the initial work-up and management of osteomyelitis in children.

From 1974 to 1983, inclusive, 274 children with acute suppurative osteoarticular infections were treated with antibiotic regimens that were shorter than usually recommended. The median duration of antibiotic treatment for acute suppurative arthritis caused by staphylococci, streptococci, Haemophilus influenzae type b, gram-negative cocci, or other gram-negative bacteria was 23, 16, 16, 15, and 22 days, respectively. For acute osteomyelitis caused by staphylococci, streptococci, H influenzae, or other gram-negative bacteria the median duration of antibiotic therapy was 24, 23, 17, and 22.5 days, respectively. Osteoarthritis usually had to be treated for about a month. 180 patients received large dosages of oral antimicrobials after clinical stabilisation with intravenous treatment, the median duration of intravenous therapy being about a week (range up to 7 weeks). 99% of patients underwent needle aspiration for diagnostic reasons. 36%, 71%, and 63% of the patients with acute suppurative arthritis, osteomyelitis, and osteoarthritis, respectively, underwent incision and drainage. Recurrence occurred in 4 patients with acute osteomyelitis (3.8% of cases). There was no recurrence of arthritis.

Twenty-five infants and children with acute osteomyelitis (n = 7), suppurative arthritis (n = 11), or both (n = 7) were treated with imipenem and cilastatin sodium. Patients ranged in age from 5 months to 11.3 years. Needle aspiration of infected sites was performed in all patients, and 11 (44%) required further surgical drainage. Imipenem and cilastatin sodium in a dosage of 100 mg/kg/d was used for children 3 years of age or younger, while older ones received 60 mg/kg/d intravenously, divided in four equal doses. Bacterial pathogens were identified in 15 patients (60%): Staphylococcus aureus in five, Haemophilus influenzae b in four, Pseudomonas aeruginosa in two, Streptococcus pneumoniae in one, group A Streptococcus in one, Kingella kingae in one, and Citrobacter amalonaticus in one. All isolates were susceptible to imipenem in vitro. Imipenem and cilastatin therapy was continued for a median of six days followed by treatment with appropriate orally administered antibiotics. Median peak serum bactericidal titers after imipenem and cilastatin infusions were 1:512 for S aureus, 1:32 for H influenzae b, 1:512 for streptococci, and 1:16 for gram-negative rods. All but one patient with P aeruginosa osteomyelitis responded favorably to imipenem and cilastatin. The median duration until resolution of symptoms was six days. Imipenem and cilastatin infusions were well tolerated, and side effects included maculopapular rash in one patient, watery diarrhea in one, and mild transient elevation of alanine aminotransferase levels in three. Because of imipenem and cilastatin's unusually broad spectrum of activity and its relative safety, this drug combination can be used for the initial, empiric therapy of acute bone and joint infections in pediatric patients.

A survey of the 58 patients with acute osteomyelitis seen in one general hospital between 1969 and 1979 has shown that, although the condition is less common now than in the pre-antibiotic era, it remains a serious disease. Bone pain and tenderness are still the commonest symptoms, but the source of the infection is less apparent now than it used to be, and this may lead to delay in diagnosis. The antecedent trauma experienced by nearly half the patients probably predisposes to infection by causing local bone damage and thus a focus for secondary infection. The pattern of infecting organisms has not changed much over the past 11 years, but Haemophilus influenzae must be considered in children aged under 5 years. Treatment was the use of antibiotics, with surgical drainage if necessary. The commonest antibiotic used was clindamycin, and chronic osteomyelitis did not develop in patients treated with this antibiotic, whereas all 9 patients who had chronic sequelae necessitating sequestrectomy had received cloxacillin either alone or in combination with another antibiotic.

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).

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.

Sixty children younger than 3 years with culture-positive hematogenous septic arthritis and acute/subacute osteomyelitis treated between 1990 and 1995 were reviewed to identify the infecting organism. Gram-positive bacteria were identified in 47 (78.3%) patients, and gram-negative organisms were identified in 13 (21.7%) patients. Haemophilus influenzae was cultured in none of the cases of septic arthritis and in only one (1.6%) case of acute osteomyelitis. Kingella kingae was cultured in 10 (16.7%) cases, with all of these patients between the ages of 10.5 and 23.5 months. Routine immunization of infants against H. influenzae has caused a change in the historically reported bacteria of bone and joint infections in children younger than 3 years. Haemophilus influenzae has lost its predominance as the most commonly identified gram-negative pathogen, and in this study, has been replaced by K. kingae.

A 36-year-old patient who was otherwise healthy had acute osteomyelitis of the humeral shaft develop after routine prophylactic dental cleaning and ultrasonic scaling. Haemophilus aphrophilus grew on cultures of material obtained during biopsy of the humerus, and pathologic examination confirmed the diagnosis of acute osteomyelitis. Haemophilus aphrophilus, a fastidious gram negative bacillus, is part of the normal oral flora and is a rare pathogen. Osteomyelitis caused by Haemophilus aphrophilus has not been reported to occur after routine dental prophylaxis. The patient was treated successfully with surgical debridement and appropriate antibiotics.

The aim of this study is to report the pathogens which were found most frequently to be responsible for osteo-articular infections in infants and children in Belgium, and to propose an appropriate empirical antibiotic therapy applicable before identification of the responsible pathogen. Clinical presentation, imaging and blood biology are also reviewed and analysed. Fifty-six cases of osteo-articular infections (acute/subacute osteomyelitis, osteo-arthritis, septic arthritis, spondylodiscitis, sacro-iliitis) treated between 2001 and 2007 were retrospectively reviewed, focusing on clinical, biological, microbiological and radiological data. Septic arthritis, acute osteomyelitis, septic osteoarthritis and sacro-iliitis often have a loud clinical (fever, pain, inflammatory signs) and biological presentation. Subacute osteomyelitis and spondylodiscitis are almost asymptomatic, but for functional impairment. The responsible pathogen was isolated in 38% of the cases. The most frequent pathogen was Staphylococcus Aureus, followed by Pneumococcus, Streptococcus A and B, Kingella Kingae, and Haemophilus. None of them were resistant to usual antibiotics. Functional impairment is the only constant symptom of osteo-articular infections. Other clinical and biological symptoms may be absent, making diagnosis often difficult. We recommend oxacillin (> 5 years) or a combination of oxacillin with cefotaxime (< 5 years) in the empirical treatment of osteo-articular infection, and a total of 4 weeks of treatment.
