Gentamicin (GM) was intramuscularly injected to 16 children with various infectious disease (1 septicemia, 1 purulent meningitis, 4 bronchopneumonia, 1 pyothorax, 3 pyelonephritis, 2 acute cystitis and 4 RITTER'S dermatitis). The results obtained are as follows: 1. The excellent and good clinical results were noted in all patients except for an indeterminate case with bronchopneumonia because of the concomitant therapy with CEZ. The effective rate was 100.0%. This was possibly because of quite high susceptibility (See Article) of all isolates to gentamicin. 2. Doses of GM were adjusted depending on the style of infectious diseases. The satisfactory clinical results were obtained in some cases by increasing its recommended dosage to about 5-8 mg per kg per day. 3. No kidney dysfunction, liver dysfunction, the 8th cranial nerve damage, etc. were observed by administering 5 to 8 mg per kg per day for at maximum 18 days, in this clinical trial. 4. It has been indicated in this clinical trial that GM is worthy to be used as a first-choice drug in chemotherapy of infectious diseases caused by Staphylococcus, gram-negative bacillus, etc., especially in patients who are hypersensitive to penicillin and cephalosporin derivatives. However, further study would be required for the safety of increase in its dosage and duration of administration.

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.

SQ 14,359 is a new cephamycin-type (7alpha-OCH3) antibiotic belonging to a series containing a 7alpha-ureidoacetyl substituent. The compound is the most potent extended spectrum derivative of this type yet reported, surpassing CS-1170 and cefoxitin by a wide margin. This activity in vitro which extends throughout the Enterobacteriaceae is particularly prominent against Gram-negative organisms that are producers of "cephalosporinase-type" beta-lactamases such as Enterobacter, Serratia, Citrobacter and indole-positive Proteus species. Superior activity also is demonstrated in vitro against streptococci, beta-lactamase-producing staphylococci, Haemophilus influenzae, Neisseria gonorrhoeae, and many Gram-negative pathogens resistant to aminoglycoside antibiotics. Experimental chemotherapeutic studies have confirmed these observations in wound and selected systemic infections in mice as well as acute pyelonephritis and meningitis in rats. The pharmacokinetics for each drug including antibiotic bound to serum was similar in both mice and rats. The pharmacokinetic profile in blood and cerebrospinal fluid favored SQ 14,359.

Prostaglandin concentrations of cerebrospinal fluid (CSF) of 38 febrile patients (from infants up to adults) were compared with those of 19 afebrile adult control persons. CSF samples were extracted and the prostaglandins groups of the extract separated by column chromatography. Concentrations of prostaglandins of the E and F series were estimated by radioimmunoassay. In CSF of all feverish patients with meningitis, pneumonia, or pyelonephritis about 2-fold higher concentrations of prostaglandin E (PGE) were found that in those of the afebrile control persons. In contrast, concentrations of prostaglandin F (PGF) in adults and infants remained largely unchanged during fever; Solely, in 4 of the 8 babies examined, concentrations of PGF were also increased besides those of PGE. Repeated estimations of prostaglandin concentrations in CSF from the same patients showed, that concentrations of PGE, which had been elevated during fever, normalized after defervescence. The height of fever and the concentrations of PGE in CSF tended to correlate in a dose related manner. In correspondence with the results of animal experiments prostaglandins of the E series seem to act as mediators of fever during infectious diseases also in man.

Concentrations of prostaglandins of the E and F series were estimated by radioimmunoassay in cerebrospinal fluid (CSF) of 30 febrile patients (infants and adults) and of 19 afebrile, adult patients. In CSF of all feverish patients with meningitis, pneumonia, or pyelonephritis, concentrations of prostaglandins of the E series were about twice higher than those of the afebrile subjects. In contrast, concentrations of prostaglandins of the F series remained largely unchanged during fever. In accord with the results of animal experiments prostaglandins of the E series seem to act as mediators of fever during infectious diseases also in man.

The pharmacokinetics and the clinical effectiveness of meropenem (MEPM) were examined in the field of pediatrics. The results are summarized as follows. 1. A 4-year-6-month-old girl with suppurative meningitis (Haemophilus influenzae) was treated by intravenous drip infusion of MEPM in a daily dose of 29 mg/kg which was divided into 4 dosages, each dosage being infused over 30 minutes, and the drug concentration in cerebrospinal fluid was determined. Upon completion of infusion on the 2nd day of treatment, the drug concentration was 2.52 micrograms/ml, which corresponded to 3.6% of the drug concentration in the blood. 2. MEPM was used in 10 patients, including 3 with suppurative lymphnoditis, 2 with staphylococcal scalded skin syndrome (SSSS) and 1 each with pneumonia, suppurative meningitis, suppurative knee arthritis, facial phlegmon and pyelonephritis. The daily doses ranged from 30 to 117.6 mg/kg, divided into 3 to 4 dosages and administered via intravenous drip infusion over 30 minutes. Clinical responses were evaluated as very good in 7 patients, good in 2 patients and fair in 1 patient, with an efficacy rate of 90%. 3. Isolated pathogens were 2 strains of Staphylococcus aureus, 1 strain of Klebsiella pneumoniae and 3 strains of Haemopilus influenzae. All of the 6 strains were eradicated, with an eradication rate of 100%. 4. In the safety evaluation, none of the patients was observed to have any side effects. Furthermore, no abnormal variations were found in laboratory test data possibly attributable to administration of MEPM.

Many discriminative experimental animal models of infection have been utilized in the evaluation of newer fluoroquinolones. In vivo efficacy of many of the newer agents has been shown in experimental models of meningitis, endocarditis, pneumonia, urinary tract infections, pyelonephritis, osteomyelitis, abscesses of various types, septic arthritis, gastroenteritis, salmonellosis, listeriosis, tuberculosis, syphilis, sinusitis, prostatitis and burn wound sepsis, among others. This review focuses on recent developments in a few selected areas. Although the limitations of animal model studies are well described, these results provide a rationale for the appropriate clinical usage of the newer fluoroquinolones in humans.

Back pain and a cervicobrachial syndrome, as well as progressive sensory and motor deficits as far as symptoms of paraplegia, developed in two dialysis patients two and five years after the start of dialysis. One was a 60-year-old woman with pyelonephritis, the other a 55-year-old man with glomerulonephritis. There were typical radiological signs of destructive spondylarthropathy (narrowed intervertebral spaces and slippage of the vertebral bodies). The female patient required several operations (spondylothesis and orthothesis) and both patients received daily 10,000 IU vitamin D and 3-4 g calcium carbonate. In the woman the destructive process no longer progressed one year after onset of symptoms, but she still required many analgesics. She died three months later of circulatory failure. The man died four weeks after the onset of symptoms from purulent meningitis. At autopsy only renal fibrous ostitis was still demonstrable. Amyloidosis resulting from an increase in beta 2-microglobulin level were excluded by both histological and immunohistochemical examinations.

The in vitro activity, pharmacokinetics, bactericidal activity, and tissue penetration of aztreonam suggest that it may play a role in therapy for serious gram-negative bacterial infections in children. Several thousand children throughout the world received aztreonam during open or comparative clinical trials for treatment of infections including pyelonephritis, bacteremia, meningitis, skeletal infection, pneumonia, and peritonitis. Cure rates have ranged from 92% to 100%, with relapses seen mainly in children with obstructive renal lesions and those with infections caused by Salmonella. A comparative trial of aztreonam for treatment of neonatal sepsis showed it to be at least as effective as amikacin for this infection. Aztreonam yielded clinical results comparable to those of conventional combined therapy for pulmonary infection in patients with cystic fibrosis. Adverse effects in pediatric trials have been uncommon; fever, diarrhea, or rash occurred in less than 2% of treated children. Reversible laboratory abnormalities have occasionally been noted. On the basis of these data, aztreonam is considered an appropriate alternative agent for the treatment of serious gram-negative bacterial infections in neonates and children. Further comparative clinical trials will delineate specific indications.

Decisions on treatment times with antibiotics are often arbitrary and based on empirical decisions or clinical trials which are too small to exclude even considerable differences between two study groups. Single-dose treatment of uncomplicated cystitis in women has been advocated by many but a careful analysis of available information clearly shows that a single-dose has so far always been inferior to 3-day or greater than 5-day treatment. With trimethoprim-sulphonamide combinations, no further efficacy is gained by increasing the treatment time in uncomplicated cystitis above three days while frequency of side effects increases drastically with extended treatment. In contrast, treatment with beta-lactams, for less than five days seems to result in unacceptable failure rates. In pyelonephritis there are few studies of the efficacy of antibiotic treatment for less than ten days. A comparison of two and six weeks' treatment showed no advantages with the extended time. There has also been a tendency towards reduced treatment times in upper respiratory tract infections such as streptococcal pharyngotonsillitis. However, two studies comparing 10-day treatment to 7-day and 5-day treatments, respectively, have clearly shown that the shorter treatment times give much higher rates of both clinical and bacteriological relapse. In more severe infections such as meningitis, no studies comparing treatment times have been carried out. It seems possible to use treatment for five days or less in meningococcal meningitis while other pathogens should be treated for ten days or longer. In endocarditis, the treatment time must vary with causative pathogens and can only rarely be shorter than four weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
