With no difference in demographics between treatment groups, overall the mean age (+/-SD) was 2.8 +/- 1.8 years, 65% had received conjugated pneumococcal vaccination and 48% had bilateral AOM. The satisfactory clinical response rate at end of therapy was comparable for cefdinir versus amoxicillin/clavulanate (88%, 170 of 194 versus 85%, 164 of 192; 95% CI -4.9, 9.3). Although this must be interpreted with caution, cefdinir showed an apparent trend for higher efficacy than amoxicillin/clavulanate (92%, 72 of 78 versus 77%, 55 of 71; P = 0.019) in a subsample of patients 6-24 months old who had received conjugated pneumococcal vaccination. The incidence of drug-related adverse events was less for cefdinir than for amoxicillin/clavulanate (24%, 50 of 211 versus 38%, 82 of 214; P = 0.0018)

The activity, safety and tolerability of the azalide azithromycin were compared with those of co-amoxiclav in the treatment of acute periapical abscesses in adults in an open, randomized, multicentre comparative study. Patients of either sex, recruited from 106 dental practices in Belgium, were aged between 18 and 75 years and had acute periapical abscesses not requiring drainage, confirmed by radiology. Azithromycin was administered as a 500-mg tablet orally once daily for 3 days (n = 150) and co-amoxiclav as a 625-mg capsule three times daily, for 5-10 days (n = 153). Both before and after treatment, masticatory pain, percussion pain, headache, and oedema and redness of soft tissue were graded on a four-point scale. Overall clinical success (cure plus improvement) was seen in 131/144 (91%) evaluable patients receiving azithromycin and in 142/148 (96%) receiving co-amoxiclav (difference not significant). There was no significant difference between the two groups in the incidence or severity of adverse events or in the number of discontinuations because of adverse events.

Retropharyngeal abscess is an uncommon entity that can have severe and even fatal complications if it is not identified and treated early. Clinical and radiologic findings must be considered together prior to surgical drainage of a suspected retropharyngeal abscess. Airway obstruction may require emergent surgical management with tracheotomy. We describe the case of a 22-year-old man with a massive retropharyngeal abscess that was caused by inadequate treatment of acute tonsillitis. He responded well to surgical drainage and empiric antibiotic therapy.

The antimicrobial spectrum and in vitro potency of the most frequently prescribed orally administered cephalosporins (cefaclor, cefdinir, cefpodoxime, cefprozil, cefuroxime axetil, cephalexin) and amoxicillin/clavulanate are reviewed. These beta-lactam agents have been widely used in the outpatient arena for the treatment of community-acquired respiratory tract and other mild-to-moderate infections. The data presented here were obtained from critical review articles on each of these compounds. Cephalexin and cefaclor were among the least potent and had the narrowest antimicrobial spectrums against the pathogens evaluated. In contrast, cefdinir, cefpodoxime, cefprozil, and cefuroxime were highly active against penicillin-susceptible Streptococcus pneumoniae and retained some activity against penicillin-intermediate strains, whereas amoxicillin/clavulanate was the most active against S. pneumoniae, including most penicillin nonsusceptible strains. Amoxicillin/clavulanate and cefdinir were the most potent compounds against methicillin (oxacillin)-susceptible Staphylococcus aureus, whereas cefpodoxime was the most potent compound against Haemophilus influenzae. Amoxicillin/clavulanate, cefdinir, and cefpodoxime were also active against Moraxella catarrhalis, including beta-lactamase-producing strains. In summary, orally administered "3rd-generation" or extended spectrum cephalosporins exhibited more balanced spectrums of activity against the principal bacterial pathogens responsible for outpatient respiratory tract and other infections when compared with other widely used oral cephalosporins of earlier generations or amoxicillin alone.

Klesiella specie isolated from clinical specimens from Ebonyi State University Teaching Hospital (EBSUTH). Abakakliki were studied to determine the antimicrobial susceptibility pattern. Between January, 2003 and September 2004 a total of 3.600 specimens processed in the routine Medical Microbiology laboratory of EBSUTH, of which 245(6.8%) yielded Klebsiella species, with 84 from out - patients and 161 from in - patients. The number of isolates from various samples were: Urine 126, Sputum 37 Endocervical swab 13, Aspirates 8, High Vaginal Swab 7, Blood 3, Eye Swab, Ear Swab and Cerebrospinal fluid were 2 samples each. Organisms were identified by conventional methods. Antimicrobial susceptibility was done by the disk diffusion methods. The antimicrobial disk used include: Ceftazidime, Cefuroxime, Cefotaxine, Augmentin, Pefloxacin (30ug), Doxycyline (25ug) Genticin (10 ug) Ciprofloacin and Ofloxacin (5ug) each and Erythromycin (15ug). All were Oxoid products. Results were interpreted according to NCCLS criteria. Klebsilla species were isolated mostly from urine specimens (51.4%) followed by wound swabs (18.4%). Antimicrobial susceptibility to various groups drugs used was generally poor. The most sensitive antimicrobial was Ciprofloxacin with 121(49.4%) isolates susceptible to it, followed by Gentamicin with 95 (38.8%) and Ceftazidime with 90(36.7%). Seventeen isolates were multiresistant to all the antimicrobial agents used. The result of this study will help in the empiric therapy of infection caused by Klebsiella species in Ebonyi State University Teaching Hospital, Abakaliki, Nigeria but continuous surverillance of antimicrobial resistance of the organnisn is very necessary in the formulation of a sound antibiotic policy in the hospital.

The rate of bactericidal activity of fleroxacin was compared with that of the combination of amoxycillin and clavulanic acid (in the proportion of 4 to 1) on beta-lactamase producing strains of Branhamella catarrhalis. The rate of bactericidal activity of 1 mg/l was as rapid as that of 1 mg/l of amoxycillin-clavulanic acid combination. This rate was not significantly more rapid if the concentrations of fleroxacin were increased to 10 mg/l. In conclusion, the bactericidal activity of fleroxacin is at least as good as that of the combination of amoxycillin and clavulanic acid. Fleroxacin showed a bactericidal effect for B. catarrhalis at concentrations that would be achieved in humans.

Three hundred four children between the ages of 6 months and 7 years with > or =1 sign or symptom of AOM were enrolled in the study, and 303 (150 cefprozil, 153 amoxicillin/clavulanate) were treated. Twenty-three patients in each treatment group were not evaluable; thus, 257 children were included in the analysis of evaluable patients. Clinical cure rates were 87% (110/127) with cefprozil and 89% (116/130) with amoxicillin/clavulanate (95% CI for the difference in cure rate, -10.7% to 4.1%). No between-group differences in efficacy were noted by age, disease severity, or unilateral or bilateral involvement. The overall incidence of drug-related adverse events was significantly lower with cefprozil than with amoxicillin/clavulanate (19% vs 32%, respectively; P = 0.008), as was the incidence of diarrhea (9% vs 19%, respectively; P = 0.021). Adverse events prompted discontinuation of therapy in 4 (3%) cefprozil patients and 8 (5%) amoxicillin/clavulanate patients.
