The efficacy and safety of cefadroxil in the treatment of paediatric patients with a wide variety of infections were evaluated in a multicentre clinical trial. This study included 395 infants and children with Group A streptococcal pharyngitis, sinusitis, otitis media, bronchitis, pneumonia or bronchopneumonia, urinary tract infections and acute gastroenteritis. Cefadroxil was given as a suspension in a daily dose of 30 to 50 mg/kg in 2 divided doses every 12 hours to all but 76 patients; 50 patients with acute otitis media were given 100 mg/kg/day in 2 doses and 26 patients with urinary tract infections received 25 mg/day once daily. Of 317 patients with respiratory tract infections and 78 with urinary or gastrointestinal infections, 95 and 100%, respectively, were clinically cured following treatment with cefadroxil.

This study compared the clinical features of diarrhea in breastfed and bottle-fed infants in Indonesia. Study subjects included 375 infants (221 breastfed, 88 bottle-fed, and 66 fed by a combined method) under 2 years of age admitted to Gunung Wenang Hospital with diarrhea. Both the duration of diarrhea and the prevalence of prolonged diarrhea were significantly greater in bottle-fed than breastfed infants. Diarrhea persisted for 8-14 days among 17% of breastfed infants, 28% of bottle-fed infants, and 35% of infants fed by a combined method. The mean duration of diarrhea was 5.5 days among breastfed infants compared with 7.2 days among bottle-fed infants. Also noted was a significantly greater incidence of acute otitis media and rhinopharyngitis among bottle-fed infants. The prevalence rates of pneumonia, bronchitis, encephalitis, and pyelonephritis were not associated with type of infant feeding. It is suggested that acute infantile diarrhea may damage intestinal mucosa, causing an increase of foreign protein of cow's milk absorption and leading to the development of further intestinal mucosal damage and prolonged diarrhea. During episodes of diarrhea in bottle-fed infants, it is advisable to substitute low allergic milk or chicken meat porridge to avoid cow's milk intolerance.

Fundamental and clinical studies on cefotetan (CTT), a new cephamycin antibiotic, were carried out under a joint study programme in pediatric field, and the following results were obtained. Pharmacokinetic study In 20 pediatric patients with normal renal function, weighing 15 to 48 kg, CTT was injected intravenously at 20 mg/kg in 3 to 5 minutes. The mean blood concentration of CTT was 215.6 micrograms/ml at 15 minutes after the end of injection, 90.7 micrograms/ml at 1 hour, 57.2 micrograms/ml at 2 hours, 33.9 micrograms/ml at 4 hours and 10.2 micrograms/ml at 8 hours. The half-life of the drug in the beta-phase, computed from the mean blood concentrations up to 8 hours postdosing, was 2.61 hours. The peak of the mean urinary excretion of cefotetan appeared in 0 to 2 hours after the injection and 36.5% of the dose was recovered in the urine. The mean excretion at 0 to 8 hours was 68.1%. Clinical study Clinical effects of CTT was evaluated in 285 patients with 287 diseases, since 1 patient had both pneumonia and erysipelas, and another both pneumonia and acute otitis media. Daily dosage of CTT ranged from 15 to 123 mg/kg, and 266 patients (93.3%) received the drug either 2 or 3 times daily. The clinical response was seen in 83.3% of the 6 cases with sepsis, 89.3% of the 122 cases with pneumonia with or without pyothorax, 96.2% of the 52 cases with either acute bronchitis or tonsillitis, 92.5% of the 67 cases with urinary tract infection and 92.5% of the 40 cases with other infections. The causative organisms were detected in 160 patients and the rate of complete disappearance was 80.6%. Out of 310 patients, side effects were seen in 9 cases, diarrhea in 8 (2.6%) and rash in 1 (0.3%). Abnormal clinical laboratory findings were seen in 24 cases, elevation of serum transaminases in 19 (7.8%), elevation of TTT and LDH in 1 (0.4%) and eosinophilia in 4 (1.6%). None of these cases showed serious side effects or abnormal clinical laboratory findings. From the above results, it is concluded that CTT is one of the useful drug for treatment of infections in pediatric field.

The immotile-cilia syndrome is caused by a hereditary, inborn, ultrastructural defect of the cilia, rendering them immotile or poorly motile and thereby abolishing mucociliary clearance. Five cases are presented and the otologic manifestations are described in some detail. The syndrome should be suspected in children who have a persistent secretory otitis media with recurring bouts of acute otitis media, and a perpetual cough with repeated episodes of bronchitis. A lobar atelectasis is a frequent finding. Half the cases also have situs inversus. The immotile-cilia syndrome is of special interest to the otologist, as it seems to throw some light on the pathogenesis of secretory otitis media.

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.

Clinical effects of SY5555 dry syrup, a new oral penem antibiotic, were analysed in 20 children with various bacterial infections. Ages of the patients varied from 8 months to 14 years. Doses of SY5555 were varied from 12.8 mg/kg/day to 30.5 mg/kg/day, and it was administered in 3 divided dosages. Clinical efficacy rates were as follows; 6/7 in acute bronchitis, 5/5 in pharyngotonsillitis, 3/3 in acute otitis media and 2/2 in cystitis and 3/3 in impetigo contagiosa. The overall rate was 95.0% (19/20). Bacteriologically, eradications were obtained with 1/2 strains of Streptococcus pyogenes, 3/3 of Staphylococcus aureus, 1/1 of Haemophilus influenzae, and each of Staphylococcus epidermidis, Haemophilus parainfluenzae, coagulase-negative staphylococci and Serratia marcescens. Diarrhea was observed in 1 patient. And elevated eosinophiles or GPT was observed in one patient each. In vivo pharmacokinetics of SY5555 was examined in 2 cases. Peak plasma levels were observed at 1 hour after dosage in one patient and at 2 hours in another upon oral administration of 8.3 mg/kg of SY5555, and peak levels were 2.44 and 1.38 micrograms/ml respectively. Half-lives of SY5555 were 1.39 and 0.59 hr. Concentrations of SY5555 in urine after administration were 70.2 (2-4 hrs.) to 91.0 (0-5 hrs.) micrograms/ml, respectively. SY5555 dry syrup is considered as an useful and safe antibiotic in treating the infectious diseases in children.

SY5555 is a new oral penem antibiotic. Pharmacokinetic and clinical studies using SY5555 dry syrup (powder which is dissolved before use) were performed in pediatric patients. 1. Pharmacokinetic investigation Peak plasma concentrations of SY5555 after dose of 5 mg/kg, 10 mg/kg and 15 mg/kg were, respectively, 1.58 +/- 0.37 micrograms/ml, 2.78 +/- 0.54 micrograms/ml and 5.28 micrograms/ml at 1 hour. The average half-life with 5 mg/kg administration was 0.94 +/- 0.05 hours, that with 10 mg/kg was 1.46 +/- 0.31 hours and that with 15 mg/kg was 0.88 hours. 2. Clinical investigation Enrolled in the study were 15 patients including 5 with acute otitis media, 5 with urinary tract infections and 1 each with pharyngitis, tonsillitis, bronchitis, pneumonia and subcutaneous abscess. Responses were excellent in 4 patients, good in 8 patients, fair in 2 patients and poor in 1 patient. In the assessment of the bacteriological efficacy, 8 out of 10 strains of organism identified previous to treatment were eradicated and 2 strains were unchanged, hence the eradication rate was 80.0%. 3. No adverse reactions attributable to the drug were observed and good drug compliance were obtained. From the above results, it has been concluded that SY5555 is a highly effective and safe agent for mild to moderate respiratory and urinary tract infections in children.

Pharmacokinetic, bacteriological and clinical studies on biapenem (L-627), a newly developed carbapenem antibiotic, were performed in the field of pediatrics. 1. Antibacterial activities of biapenem against 54 strains of Streptococcus pneumoniae isolated in 1993 were compared with those of 13 other antibiotics, consisting primarily of beta-lactam compounds. Minimal inhibitory concentrations (MICs) of biapenem were < or = 0.78 micrograms/ml against all strains, and excellent values were obtained even against benzylpenicillin (PCG)-resistant strains. Based on MIC80 values, biapenem, imipenem, and cefuzonam showed highest antibacterial activities, followed by cefotaxime. 2. Blood concentrations and urinary excretion were studied after intravenous drip infusion of 6.0 mg/kg and 6.1 mg/kg of biapenem, given over 30 min., to two children (ages: 4 years and 11 years). Blood drug concentrations were 14.7 and 37.6 micrograms/ml, respectively (mean: 26.2 micrograms/ml), at 30 min. after starting infusion (at completion of infusion). Blood concentrations then declined gradually with half-lives of 0.66 and 1.16 hrs., respectively (mean: 0.91 hrs.). After 5.5 hrs., blood concentrations were no longer measurable in the former and 0.46 micrograms/ml in the latter. Urinary recovery rates of drug in the first 6 hrs. after starting administration were 65.8% and 60.9%, respectively (mean 63.4%). 3. Penetration of the drug to the cerebrospinal fluid (CSF) was studied in 2 patients with purulent meningitis. Biapenem, 31.6 mg/kg, was administered four times daily by 30-min. intravenous drip infusion. CSF concentration 1 hr. after administration was 8.54 micrograms/ml on the day of the start of treatment (day 0), and 3.00, 2.04, 16.1, 4.16, 3.24, and 1.60 micrograms/ml on days 1-7 of treatment, respectively. In a patient similarly administered with the drug at 33.7 mg/kg four times daily, the CSF concentration at 1.5 hrs. after administration was 2.62 micrograms/ml on the next day of the start of treatment. On days 2-7 of treatment, CSF concentrations at 0.5-1 hr. after administration were 4.60, 12.9, 20.6, and 1.32 micrograms/ml, respectively. 4. Clinical efficacy was evaluated in 27 patients with pediatric infections. The dose administered per dosage was 5.2-33.7 mg/kg. Three or four dosages were given daily. The duration of therapy ranged from 3 1/3 to 11 days. Total administered doses were between 0.675 and 20.475 g. Clinical efficacy was evaluated in a total of 24 patients (purulent meningitis 1, acute otitis media 1, acute bronchitis 2, acute pneumonia 19, acute urinary tract infection 1). Responses to treatment were excellent in 14 patients and good in 10 patients.(ABSTRACT TRUNCATED AT 400 WORDS)

We have compared the use of primary health care and the diagnoses at visits to doctors in the Spili Health Centre (SHC) in Crete and the Dalby Health Centre (DHC) in Sweden. In DHC more patients per 1000 population visited the doctors than in SHC. This was so regardless of age-group and sex, in fact more or less regardless of diagnosis. Other differences between the populations were: The diagnosis acute otitis media was more frequent in the Dalby children than in the Spili ones. The opposite was true of "head injuries" which were more frequent in the Spili boys. Visits to doctors for bronchitis was more frequent in the Spili men, maybe because of the extensive smoking habits of Cretan men. Visits for diseases of the musculoskeletal system were more frequent in DHC than in SHC. A hypothesis worth testing is that this was influenced by differences in the health insurance and sick benefit systems. Angina pectoris was fairly frequent in both areas but cardiosclerosis (including healed myocardial infarction) was more common in DHC than in SHC. Use of primary health care may be influenced by the need for health care in the population, the accessibility of the health care facilities, the costs for the patients, the quality of care as perceived by the patients and by other sociocultural factors. Comparative studies, even though fairly uncommon today, may be of use in generating hypotheses about the impact of different factors on the use of health care.

Cefuroxime axetil is an oral cephalosporin which is rapidly hydrolysed to the active parent compound, cefuroxime. Cefuroxime has a broad spectrum of in vitro antibacterial activity which encompasses methicillin-sensitive staphylococci and the common respiratory pathogens Streptococcus pneumoniae, Haemophilus influenzae, Moraxella (Branhamella) catarrhalis and group A beta-haemolytic streptococci. Cefuroxime has broad spectrum activity against the beta-lactamase positive respiratory pathogens H. influenzae and M. catarrhalis; it is also active against penicillin-susceptible and -intermediate strains of S. pneumoniae. In clinical trials, cefuroxime axetil (administered twice daily) has been evaluated in the treatment of upper and lower respiratory tract infections and has demonstrated similar efficacy to established antibacterial agents, including amoxicillin/clavulanic acid and cefaclor. Five days' treatment with cefuroxime axetil was recently shown to be as effective as 10 days' treatment with either cefuroxime axetil or amoxicillin/clavulanic acid in patients with acute otitis media or acute bronchitis. Cefuroxime axetil was at least as effective as phenoxymethylpenicillin (penicillin V) in the treatment of patients with group A beta-haemolytic streptococcal tonsillopharyngitis. A number of studies have evaluated the efficacy of cefuroxime axetil as the oral component of intravenous to oral sequential therapy in hospitalised patients with lower respiratory tract infection. In each study patients received parenteral cefuroxime for approximately 2 days followed by cefuroxime axetil for 5 to 10 days. In comparative studies, cefuroxime sequential therapy was as effective as amoxicillin/ clavulanic acid sequential therapy and full courses of parenteral cefuroxime, cefotiam or cefoperazone. Adults with urinary tract infections and skin infections were also effectively treated with cefuroxime axetil, as were adults and adolescents with early stage lyme disease. Cefuroxime axetil is associated with a low incidence of adverse events, with gastrointestinal disturbances being the most frequently observed. Thus, cefuroxime axetil is an effective and convenient treatment for a wide range of infections and may be considered a therapeutic option when empirical treatment of community-acquired infections is required. Moreover, given the promising results of several intravenous/oral sequential treatment studies, cefuroxime axetil may also become established as an oral component of sequential treatment regimens.
