We carried out clinical and bacteriological studies on clavulanic acid/amoxicillin and amoxicillin in pediatric acute otitis media at 14 general practice settings. The results are summarized as follows. 1. The major isolated organisms from content of middle ear effusion were Streptococcus pneumoniae 31.8%, Haemophilus influenzae 35.8% and Moraxella subgenus Branhamella catarrhalis 1.5%. Similar results were observed for the major isolates organisms from content of nasopharynx Streptococcus pneumoniae 31.1%, Haemophilus influenzae 33.9% and Moraxella subgenus Branhamella catarrhalis 19.2%. 2. 42.2% of S. pneumoniae isolated from middle ear effusion were drug resistant S. pneumoniae (PISP, PRSP) and they were increasing year by year. 3. 46.7% of S. pneumoniae isolated from nasopharyngeal swab were drug resistant S. pneumoniae (PISP, PRSP) and they were increasing year by year. The incidence of drug resistant S. pneumoniae isolated from all cases and organisms were 26.3% and 14.5%, respectively. 4. On MIC90, antimicrobial activity of CVA/AMPC against Streptococcus pneumoniae, Haemophilus influenzae and Moraxella subgenus Branhamella catarrhalis was superior to SBTPC. 5. In the evaluation of clinical efficacy, bacteriological efficacy and utility, CVA/AMPC-treated group was significantly superior to AMPC-treated group. 6. Adverse reactions were observed in 22% of CVA/AMPC-treated group, involving diarrhea and loose stool.

We carried out clinical and bacteriological studies on clavulanic acid/amoxicillin and amoxicillin in pediatric sinusitis at 11 general practice settings. The results are summarized as follows. 1. The major isolated organisms from content of middle meatus were Streptococcus pneumoniae 32.2%, Haemophilus influenzae 32.0% and Moraxella subgenus Branhamella catarrhalis 25.1%. Similar results were observed for the major isolates from nasopharynx. 2. 62.1% of S. pneumoniae isolated were drug resistant S. pneumoniae (PISP, PRSP) and they were increasing year by year. 3. Drug resistant S. pneumoniae was isolated from 38.6% of all cases. 4. Regarding MIC90, CVA/AMPC showed superior antimicrobial activity against Streptococcus pneumoniae, Haemophilus influenzae and Moraxella subgenus Branhamella catarrhalis. 5. The clinical efficacy, bacteriological efficacy and utility of CVA/AMPC-treated group were 78%, 58% and 72.8%, respectively, and they were significantly superior to AMPC-treated group. 6. Adverse reactions were observed in 11.2% of CVA/AMPC group, involving diarrhea and stool loose and there was no statistical deference from those of AMPC group.

Nasal sinusitis, tonsillitis, and pharyngolaryngitis typify upper respiratory tract infections, while bronchitis and pneumonia typify lower respiratory tract infections. Cases of paranasal sinusitis with severe suppuration are reportedly becoming less frequent, while those of chronic catarrhal paranasal sinusitis and edematous allergic paranasal sinusitis are becoming more so, The primary factor in paranasal sinusitis, a typical infectious disease encountered in otolaryngology, is bacterial infection. The main causative bacteria are Streptococcus pneumoniae, reported in 13.4% of cases, Haemophilus influenzae in 12.8% Moraxella catarrhalis in 5.5%, Staphylococcus aureus in 26.5%, Pseudomonas aeruginosa in 5.2%, and anaerobes. The incidence of strains resistant to antimicrobial agents has grown for S. pneumoniae, H. influenzae, and M. catarrhalis and decreased for S. aureus and P. aeruginosa. Acute exacerbation or severe suppuration in chronic paranasal sinusitis requires the administration of antimicrobial agents, with the same agent administered 2 weeks for maximal effect. First-line agents are AMPC/CVA, SBTPC, CDTR-PI, CFPN-PI, and GFLX for adults, with ASPC, SBPC, ACPC, CTRX, CMZ, FMOX, PAPM/BP, and MEPM injected in severe cases. Attention must be paid to strains that resist cephems and macrolides, such as PISP, PRSP, and BLNAR. In refractory chronic paranasal sinusitis, attention must also be paid to biofilms produced by S. aureus and P. aeruginosa. Suitable antimicrobial agents should be determined for treating of chronic paranasal sinusitis, in addition to the best procedure to ensure early recovery from inflammation, such as puncturing or irrigating the maxillary sinus, injecting a suitable agent, nebulization, and/or surgically widening the middle meatus.
