Previous studies suggest that the unexplained sudden and severe onset of obsessive-compulsive disorder (OCD) and/or tics may be infection or immune precipitated. Beta lactam antibiotics may be neuroprotective beyond their antimicrobial efficacy. We examine the preliminary safety and efficacy of cefdinir in reducing obsessive-compulsive and/or tic severity in children with new-onset symptoms.

Achromobacter spp. should be recognized as causative agents for device-related ophthalmic infections. Molecular species identification by 16S rDNA sequence analysis should be combined with conventional cultivation techniques to investigate the significance of Achromobacter spp. in ophthalmic infections.
A total of 2767 children with severe acute malnutrition were enrolled. In the amoxicillin, cefdinir, and placebo groups, 88.7%, 90.9%, and 85.1% of the children recovered, respectively (relative risk of treatment failure with placebo vs. amoxicillin, 1.32; 95% confidence interval [CI], 1.04 to 1.68; relative risk with placebo vs. cefdinir, 1.64; 95% CI, 1.27 to 2.11). The mortality rates for the three groups were 4.8%, 4.1%, and 7.4%, respectively (relative risk of death with placebo vs. amoxicillin, 1.55; 95% CI, 1.07 to 2.24; relative risk with placebo vs. cefdinir, 1.80; 95% CI, 1.22 to 2.64). Among children who recovered, the rate of weight gain was increased among those who received antibiotics. No interaction between type of severe acute malnutrition and intervention group was observed for either the rate of nutritional recovery or the mortality rate.

Of 447 children enrolled, 230 were clinically and bacteriologically evaluable (74% 2 years old or younger; 57% treated for AOM in previous 3 months). Bacteriologic eradication, based on repeat tympanocentesis on days 4-6, was achieved in 74% (170 of 230) of children; 76% (201 of 266) of AOM pathogens were eradicated. Eradication of penicillin-susceptible, -intermediate and -resistant S. pneumoniae was 91% (50 of 55), 67% (18 of 27) and 43% (10 of 23), respectively (P < 0.001); eradication of H. influenzae was 72% (90 of 125). Overall clinical response at days 12-14 was 83% (76 and 82% for children with S. pneumoniae and Haemophilus influenzae, respectively). Sustained clinical response at days 25-28 was 85%. Clinical response was 83% for culture-positive children versus 96% for culture-negative children at baseline tympanocentesis (P < 0.001).

We examined the attachment of Staphylococcus aureus to plastic tissue-culture coverslips after incubation for 24 h. The attachment to coverslips was weaker in rabbit plasma with 5% zinc oxide (ZnO) than in the control rabbit plasma without ZnO (P < 0.01). Plasma coagulation by S. aureus strains was not detected in plasma with 5% ZnO after incubation for 24 h. The membranous structure (an immature biofilm) was formed on the coverslips by S. aureus cells in plasma after incubation for 24 h. The colony counts of S. aureus cells on the membranous structures were lower in plasma with 5% ZnO, plasma with 0.2% hinokitiol, plasma with 5% ZnO + 0.2% hinokitiol, plasma with cefdinir at 4 minimum inhibitory concentration (MIC) and plasma with levofloxacin at 4 MIC, than in the control plasma after incubation for 24 h (P < 0.01). The colonies on the membranous structures completely disappeared in the case of plasma with 5% ZnO and 0.2% hinokitiol. The colony counts on membranous structures were lower in plasma with cefdinir at 4 MIC or levofloxacin at 4 MIC containing 5% ZnO than in plasma with cefdinir at 4 MIC or levofloxacin at 4 MIC only, (P < 0.05). The MICs of hinokitiol against S. aureus strains peaked at an MIC distribution of 16-32 micrograms/ml. The peak shifted to below 1 microgram/ml by adding 5% ZnO in agar plate method. The results suggest that the attachment of S. aureus cells to the coverslips is suppressed in the presence of 5% ZnO and that antistaphylococcal activities of cefdinir, levofloxacin and hinokitiol increase in the presence of 5% ZnO.

Impetigo can result from Staphylococcus aureus (S. aureus). Wolf's isotopic response is the occurrence of a new cutaneous disorder at the site of a previously healed disease. A cutaneous immunocompromised district is an area of skin that is more vulnerable than the rest of the individual's body.
We studied the clinical efficacy of cefdinir (CFDN), a new oral cephalosporin, in 18 children with ages 2 years and 4 months to 11 years and 4 months with pediatric infections. The diagnoses consisted of respiratory tract infections in 15 cases, impetigo in 2 and balanoposthitis in 1. Clinical efficacies were excellent in 11 patients and good in 7, with an efficacy rate of 100%. Bacteriologically, 9 (64.3%) of the 14 strains of clinical isolates were eradicated. No side effects nor abnormal laboratory findings were observed. We have concluded that CFDN is a useful antibiotic for the treatment of mild to moderate pediatric infections.

Antimicrobial susceptibilities for fosfomycin (FOM), cephalexin, cefpodoxime, cefdinir, cefditren, ampicillin, sulbactam/ampicillin, imipenem (IPM), panipenem, meropenem (MEPM), biapenem, levofloxacin (LVFX), gatifloxacin, pazufloxacin, prulifloxacin and sulfamethoxazole/trimethoprim were determined by an agar dilution method using Mueller-Hinton agar (MHA) in Escherichia coli, Klebsiella spp., Serratia marcescens, Citrobacter spp., Enterobacter spp. and Proteus mirabilis, which were isolated from patients in 2003-2004. Those for FOM were determined by the agar dilution methods using MHA containing glucose-6-phosphate (G6P) under aerobic conditions, MHA under anaerobic conditions and nutrient agar under aerobic conditions. Those for FOM, LVFX, IPM and MEPM were also determined by an Etest method. The results by the agar dilution method showed that carbapenems had good antibacterial activities in all isolates, whereas MIC ranges for other antimicrobials were broad. Our results showed that the agar dilution method for FOM using MHA containing G6P under aerobic conditions provided reliable MICs in E. coli, which agreed with data previously reported. The results by the agar dilution method for LVFX, IPM and MEPM showed the high rate of agreement compared with those by the Etest method. In E. coli, the results for FOM by the agar dilution method using MHA containing G6P showed the high rate of agreement compared with the Etest results, although the rate was affected by bacterial species and culture conditions in various ways.

Of 393 isolates of Streptococcus pneumoniae from U.S. children collected in 2005-2006, nonvaccine serotypes accounted for 89.1%, with serotype 19A the most prevalent, representing 30.5% of all isolates. The MIC(90) of faropenem against serotype 19A isolates was 1 mug/ml, compared to > or =8 microg/ml against amoxicillin/clavulanate, cefdinir, cefuroxime axetil, and azithromycin.
ss-Lactamase-producing (BLP) strains with the bla gene were identified in 16 (2.5%) of isolates. PGM strains were identified in 279 (43.3%) isolates. There were 242 (37.6%) PGM1-nonBLP strains with mutations in variable mutated locus of ftsI, 35 (5.4%) PGM2-nonBLP strains with mutations in highly mutated locus of ftsI, 2 (0.3%) BLP-PGM strains with mutations in ftsI and producing ss-lactamase. BLP-nonPGM strains producing ss-lactamase without mutations in ftsI were identified in 14 (2.2%) isolates. MICs of PGM1-nonBLP strains to AMP were 0.5-2.0 microg/ml. The MIC(90) of CDN to the PGM1-nonBLP strains was lowest (0.06 microg/ml). Proportions of PGM1-nonBLP strains rapidly increased during 1999 to 2002 and then decreased in 2003. In contrast, PGM2-nonBLP strains increased in 2003.
FK482 is an oral aminothiazolyl hydroxyimino cephalosporin with a C-3 vinyl group. Its activity was compared with those of cephalexin, cefuroxime, cefixime, and amoxicillin-clavulanate. FK482 inhibited 90% of Staphylococcus aureus isolates at 1 micrograms/ml and 90% of Streptococcus pyogenes, Streptococcus agalactiae, and Streptococcus pneumoniae isolates at less than or equal to 0.012 micrograms/ml, superior to cephalexin and cefuroxime and similar to cefixime. It did not inhibit oxacillin-resistant S. aureus. FK482 inhibited 90% of Enterococcus faecalis isolates at 8 micrograms/ml. Although 90% of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella species, and Shigella species isolates were inhibited by less than or equal to 2 micrograms/ml, FK482 was less active than cefixime against Citrobacter, Enterobacter, Morganella, Serratia, and Providencia species, with MICs for many isolates of greater than 8 micrograms/ml. FK482 inhibited Haemophilus influenzae and Neisseria gonorrhoeae at concentrations comparable to that of cefixime and superior to those of cephalexin and cfaclor. Bacteroides and Pseudomonas species were resistant. FK482 was not hydrolyzed by the TEM-1 and TEM-2 beta-lactamases but was hydrolyzed by TEM-3 and the Proteus vulgaris enzyme. It had a high affinity for chromosomal beta-lactamases.
The therapeutic activities of orally administered FK482 were compared with those of reference antibiotics against systemic and local infections with a variety of bacteria in mice and rabbits. In systemic infections in mice, oral FK482 was almost as effective as oral cefaclor (CCL) and more effective than oral cephalexin (CEX) against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis infections. However, FK482 afforded superior protective activity when given subcutaneously against E. coli infection in mice, and this activity was more potent than that of subcutaneously given CCL. In comparison with CCL, the reason that the in vivo activity of orally given FK482 against mouse systemic infections was weaker than had been anticipated from its potent in vitro activity was due to its poor oral absorption in mice. In local infections in rabbits, a species in which FK482 was better absorbed than in mice, FK482 was more effective than CCL, CEX or amoxicillin (AMPC). Against pneumonia induced by S. aureus or Streptococcus pyogenes, FK482 was as effective as AMPC and more effective than CCL in reducing the number of viable bacteria in the lungs of infected rabbits. In the oral treatment of experimental ascending pyelonephritis in rabbits, FK482 was superior to CCL and AMPC against methicillin-resistant S. aureus infection, as effective as AMPC and more effective than CCL against Enterococcus faecalis infection, and as effective as cefixime (CFIX) and more effective than CCL and AMPC against E. coli infection in reducing the number of viable bacteria in the kidneys and urine.

We consider studies in which an enrolled subject tests positive on a fallible test. After an intervention, disease status is re-diagnosed with the same fallible instrument. Potential misclassification in the diagnostic test causes regression to the mean that biases inferences about the true intervention effect. The existing likelihood approach suffers in situations where either sensitivity or specificity is near 1. In such cases, common in many diagnostic tests, confidence interval coverage can often be below nominal for the likelihood approach. Another potential drawback of the maximum likelihood estimator (MLE) method is that it requires validation data to eliminate identification problems. We propose a Bayesian approach that offers improved performance in general, but substantially better performance than the MLE method in the realistic case of a highly accurate diagnostic test. We obtain this superior performance using no more information than that employed in the likelihood method. Our approach is also more flexible, doing without validation data if necessary, but accommodating multiple sources of information, if available, thereby systematically eliminating identification problems. We show via a simulation study that our Bayesian approach outperforms the MLE method, especially when the diagnostic test has high sensitivity, specificity, or both. We also consider a real data example for which the diagnostic test specificity is close to 1 (false positive probability close to 0).

Among orally administered cephalosporins, aminopenicillins (+/- clavulanate), and macrolides, cefditoren was the most potent agent against Haemophilus influenzae (MIC(50/90), < or =0.008/0.03 microg/mL; 316 isolates including 100 beta-lactamase-positive and 10 beta-lactamase-negative ampicillin-resistant [BLNAR]) and was 32-, 64-, and 512-fold more potent than cefdinir, cefuroxime, and cefprozil, respectively. Cefditoren (MIC(50), 0.03 microg/mL) was also > or =32-fold more active against BLNAR phenotypes, although newer macrolides provided complete coverage against these strains. All Moraxella catarrhalis isolates were inhibited by cefditoren (0.5 microg/mL), including beta-lactamase producers (MIC(50), 0.12 vs < or =0.008 microg/mL). Cefditoren retains potent activity against respiratory tract isolates in the United States, including those with resistance phenotypes.

The in vivo antibacterial activities of a new oral trinem, sanfetrinem cilexetil (a prodrug of sanfetrinem), were evaluated in comparison with those of cefdinir and amoxicillin. Sanfetrinem cilexetil showed potent efficacy against experimental murine septicemia caused by Staphylococcus aureus, Streptococcus pyogenes, and Escherichia coli and against murine respiratory infections caused by Streptococcus pneumoniae. Likewise, in murine models of respiratory infection by penicillin-susceptible and penicillin-resistant S. pneumoniae, sanfetrinem cilexetil was more effective than amoxicillin in reducing the number of bacteria in infected lungs. These results were reflected in its potent in vitro activity and high levels in plasma.
