1. Cefuroxime (CXM) was studied for absorption and excretion in 4 pediatric patients given one shot intravenous injection of 20 approximately 25 mg/kg. The following serum levels were determined: 24.5 approximately 38.0 micrograms/ml at 30 minutes (mean 33.3 +/- 6.1 micrograms/ml), 10.0 approximately 17.0 micrograms/ml at 1 hours (mean 13.9 +/- 3.3 micrograms/ml), 3.4 approximately 7.6 micrograms/ml at 2 hours (mean 5.2 +/- 1.9 micrograms/ml, 0.7 approximately 2.1 micrograms/ml at 4 hours (mean 1.3 +/- 0.6 micrograms/ml, 0.1 approximately 0.3 microgram/ml at 6 hours (mean 0.2 +/- 0.1 microgram microgram/ml). Half-life (T 1/2) was 0.65 approximately 0.88 hour (mean 0.75 +/- 0.10 hour). Urinary levels were 1,280 approximately 7,100 micrograms/ml at 0 approximately 2 hours, 96 approximately 3,400 micrograms/ml at 2 approximately 4 hours, 68 approximately 250 micrograms/ml at 4 approximately 6 hours. Urinary recovery rate at 0 approximately 6 hours was 54.1 approximately 74.4% (mean 61.8 +/- 9.4%). 2. From the study on spinal fluid concentration in pediatric patients with Haemophilus influenzae-induced meningitis, the dose of CXM 52.2 mg/kg was given to 1 pediatric case with this disease by one shot intravenous injection. Spinal fluid levels were presumed as 9.0 micrograms/ml at 30 minutes, 6.8 micrograms/ml at 1 hour, 3.8 micrograms/ml at 2 hours and 1.2 micrograms/ml at 4 hours. 3. CXM was studied in 19 pediatric patients with bacterial infection for clinical efficacy, bacteriological effect and side effect. Clinical result was found good in 1 with purulent meningitis; excellent in 9 out of 15 with acute lobar pneumonia or acute bronchopneumonia, and good in remaining 6 cases; good in 2 with acute bronchitis; excellent in 1 with acute pyelonephritis. This represents efficacy ("excellent" plus "good") rate of 100%. Of 5 strains of H. influenzae presumed as causative organisms, 4 were disappeared and 1 was reduced. Two strains of Streptococcus pneumoniae and 1 strain of Escherichia coli were disappeared. No side effect was noted in terms of clinical symptom. Laboratory examination showed elevation of GOT and GPT in 1 case, but these elevated values returned to normal after the end of the CXM treatment.

T-1982 (cefbuperazone), a new cephamycin antibiotic, was basically and clinically studied in the field of pediatrics, and the following results were obtained. 1. The antibacterial activity of T-1982 was compared with that of CEZ, CMZ and ABPC. T-1982 was more active than the other drugs against Gram-negative bacteria, the sensitivity of E. coli (22 strains), K. pneumoniae (18 strains), P. mirabilis (19 strains), P. vulgaris (4 strains), P. morganii (5 strains) and K. oxytoca (4 strains) distributing less than 0.39, 0.1, 1.56, 0.39, 6.25 and 0.2 microgram/ml, respectively. Two of 3 strains of C. freundii were inhibited by 12.5 micrograms/ml. Against Gram-positive bacteria, the activity of T-1982 was inferior to that of the other drugs. S. pyogenes (28 strains) were inhibited by 0.78 microgram/ml or less, but the sensitivity of S. aureus (34 strains distributed 12.5-100 micrograms/ml). 2. T-1982 was administered to each 3 children at a dose of 20 mg/kg by one shot intravenous injection or 1 hour drip infusion, or at dose of 40 mg/kg by 1 hour drip infusion. The mean serum levels at 0.25, 0.5, 1, 2, 4 and 6 hours after one shot intravenous injection of 20 mg/kg were respectively 74.3, 56.3, 42.3, 17.6, 5.7 and 1.2 micrograms/ml with the mean half-life of 1.01 hours. The values were 32.9, 50.0, 73.7, 27.5, 12.4 and 4.5 micrograms/ml and 1.31 hours by intravenous drip infusion of 20 mg/kg and 50.4, 104.7, 136.3, 62.3, 18.6 and 6.9 micrograms/ml and 1.16 hours by intravenous drip infusion of 40 mg/kg. The mean urinary recovery rates within 6 hours were 47.7, 67.6 and 60.9%, respectively. 3. Treatment with T-1982 was made in 28 cases of pediatric infections; 1 case of acute bronchitis, 19 cases of acute bronchopneumonia or lobar pneumonia, 2 cases of acute purulent cervical lymphadenitis, 4 cases of acute pyelonephritis and each 1 case of subcutaneous abscess and suspected bacterial endocarditis. The clinical responses assessed in 27 cases were excellent in 21 cases, good in 5 cases and poor in 1 case, the efficacy rate being 96.3%. Bacteriologically, 2 strains of S. aureus, 3 strains of S. pneumoniae, 4 strains of H. influenzae, 2 strains of E. coli and 1 strain of P. mirabilis were eradicated. One strain of S. faecalis was reduced. No side effects were observed in any cases. Slight elevation of GOT and GPT and that of GOT were noted in each 1 case.

Fundamental and clinical studies of cefotetan (CTT) were made in pediatric field and the following results were obtained. Antimicrobial activity MIC80 values of CTT against clinically isolated S. aureus (32 strains), E. coli (33 strains) and K. pneumoniae (33 strains) were 25, 0.1 and 0.1 microgram/ml respectively. Antimicrobial activities of CTT against E. coli and K. pneumoniae were superior to those of CMZ, though the activity against S. aureus was inferior to that of CMZ. Pharmacokinetics When 20 mg/kg of CTT was administered to 3 children, who were 3 to 8 years of age, by a intravenous bolus injection, the mean serum concentrations of the drug after 1/2, 1, 2, 4, 6 and 8 hours were 110.7 +/- 9.2, 81.7 +/- 10.1, 50.0 +/- 7.5, 25.3 +/- 4.6, 14.9 +/- 5.5 and 7.7 +/- 2.8 micrograms/ml respectively, and the mean half-life (beta) was 2.01 +/- 0.32 hours. The mean concentrations of the drug in urine after 0-2, 2-4, 4-6 and 6-8 hours were 1,377 +/- 787, 1,045 +/- 689, 1,067 +/- 680 and 358 +/- 80 micrograms/ml respectively, and the mean recovery rate by 8 hours was 67.3 +/- 16.2%. Clinical study CTT was administered to 42 children of 2 monthes to 14 years of age, and clinical response, bacteriological effect and adverse reaction of the drug were studied. Clinical effects were evaluated in 8 cases of acute purulent tonsillitis, each 1 case of acute otitis media and acute bronchitis, 16 cases of acute bronchopneumonia or acute lobar pneumonia, 9 cases of acute pyelonephritis and 1 case of erysipelas, the results were excellent in 30 cases, good in 3, fair in 2 and poor in 1, and thus 91.7% of efficacy rate was obtained. Out of suspected causative organisms including 12 strains of H. influenzae, 1 strain of H. parainfluenzae, 7 strains of E. coli, 2 strains of S. pyogenes, 2 strains of S. pneumoniae and each 1 strain of S. epidermidis and S. faecalis, all the strains except each 1 strain of H. influenzae and S. faecalis disappeared after the treatment. Thus 92.3% of eradication rate was obtained. No side effects were recognized. Though abnormal laboratory findings were observed in 3 cases (7.1%), including elevation of GOT and GPT in 2 cases and eosinophilia in 1 case, those findings came to be normal after the treatment.

Headache, nuchal rigidity, positive Kernig's sign, and even convulsions may be observed during severe bacterial infections such as pneumonia, pyelonephritis, typhoid fever, and bacillary dysentery. In such cases, meningitis can be excluded only by documentation of normal cerebrospinal fluid (CSF). The authors describe four children with lobar pneumonia in whom the clinical signs of meningeal irritation were associated with a mild increase in the white blood cell count in the CSF (pleocytosis) although there was no other evidence of meningeal infection.
