Increasing prevalence of multidrug-resistant (MDR) Salmonella typhi strains in pediatric cases of typhoid fever and chemotherapy restrictions in children, such as fluoroquinolones, require ongoing clinical evaluations of different antibiotic regimens. Previously reported clinical trials with oral cefixime therapy given as a 12-day regimen (20-30 mg/kg divided twice daily) demonstrated both safety and efficacy. An open trial was undertaken to investigate a short course (8-day) regimen of oral cefixime in an Egyptian public fever hospital. Eighty children were initially enrolled with blood culture confirmation in 60 children. Clinical cure was documented in 57 (95 per cent) with three children requiring a change in antibiotic regimen due to therapeutic failure and one child with culture-confirmed relapsed 21 days post-therapy. All S. typhi isolates were sensitive to cefixime as measured by disk diffusion. Cefixime was well-tolerated with only mild side-effects, including nausea/vomiting (8 per cent) and abdominal cramping with loose stools (6 per cent), which may have been secondary to typhoid fever. Cefixime given in a short 8-day course is safe and effective in the management of MDR typhoid fever in children.

This report describes one case of verified treatment failure of pharyngeal gonorrhoea using ceftriaxone in Sweden. Previous reports described verified treatment failure of urogenital gonorrhoea using the internationally recommended first-line drug cefixime, but not with ceftriaxone, the last remaining option for empirical treatment of gonorrhoea. Enhanced awareness of clinical failures, pharmacodynamic considerations, follow-up and test of cure, adherence to appropriate case management and treatment guidelines as well as verification/falsification of presumed clinical treatment failures should be emphasised worldwide.

An intervention study was carried out in the department of paediatrics of Mymensingh Medical College Hospital, Mymensingh to compare the clinical efficacy of Azithromycin in the treatment of childhood typhoid fever with that of cefixime for a period of one year from January 2011 to December 2011. A total of 60 cases of typhoid fever were enrolled in to a randomized clinical trial and was divided into two groups. The inclusion criteria of the cases were: Documented fever for more than 4 days plus two or more of the following clinical features: toxic physical appearance, intestinal complaints, coated tongue, ceacal gurgling, hepatomegaly and splenomegaly, diarrhoea and constipation plus positive Widal test and/or blood culture positivity. Patients who had complication like GIT heamorrhage; intestinal perforaion and/or shock were excluded from the study. Data were collected in a structured questionnaire. Azithromycin was given at a dose of 10mg/kg/day for a period of 07 days Cefixime was given at a dose of 20mg/kg/day in two divided dose for 14 days. The mean time of defervesence was 4.05+1.14 days with azithromycin and 3.41+0.95 with cefixime respectively. The minimum defervesence time was 02 days and maximum defervesence time was 07 days. Clinical cure rate was 87% in azithromycin group and 93% in cefixime group. No serious adverse effect was noted related to azithromycin and cefixime therapy except nausea, vomiting, diarrhoea and jaundice. It was found that azithromycin is almost as effective as cefixime in the treatment of typhoid fever.

Infectious pharyngotonsillitis is usually managed with antibiotics by general practitioners and pediatricians both in primary care and the emergency services. In the present work we try to assess the antibiotic variability and appropriateness in the management of acute pharyngotonsillitis among several emergency services in our country related to scientific evidence based in an expert panel criteria.

Effective treatment of gonorrhoea is fundamental to public health control; however, the ability of Neisseria gonorrhoeae to successively develop resistance to different treatments has hampered control efforts. The extended-spectrum cephalosporins--cefixime and ceftriaxone--have been recommended in the UK for treatment of gonorrhoea since 2005. We looked at surveillance data from England and Wales to ascertain the current usefulness of these drugs and to inform changes to national treatment guidelines.
Out of the total number of 100 E. coli cases, 22 cases (22%) had class 1 integron. Resistance against cotrimoxazol, cefixime and ciprofloxacin antibiotics were 67%, 34% and 34% respectively. In 22 E. coli cases positive for integron class1 gene, resistance against three antibiotics were 100%, 95.45% and 90.90% respectively, which is statistically significant (p < 0.05).

The major pathogens causing acute otitis media (AOM) are Streptococcus pneumoniae and Haemophilus influenzae, with Moraxella catarrhalis, Streptococcus pyogenes, and Staphylococcus aureus less frequently isolated. The same organisms and Staphylococcus epidermidis are found in chronic otitis media with effusion. In chronic suppurative otitis media, Pseudomonas aeruginosa and S aureus are most frequently found. Antimicrobial agents found to be most effective in treating AOM are amoxicillin, trimethoprimsulfamethoxazole, erythromycin-sulfisoxazole, amoxicillin-clavulanate, and cefaclor. Cefuroxime axetil and cefixime are alternatives for which there are less data. Currently, about 20% of AOM cases are caused by beta-lactamase-producing strains (usually H influenzae or M catarrhalis) that are resistant to amoxicillin, thus favoring the use of the other agents listed. Concentrations of antibiotics in middle ear infections range from 10% to 76% of peak serum levels for the listed agents and are higher in AOM than in chronic otitis media with effusion, emphasizing the importance of adequate dosing for successful treatment.

Forty-one periodontal abscess samples were cultivated on selective and non-selective culture media to isolate the oral anaerobes. Their antibiotic susceptibilities to clindamycin, doxycycline, amoxicillin, imipenem, cefradine, cefixime, roxithromycin, and metronidazole were determined using the agar dilution method, and polymerase chain reaction assays were performed to detect the presence of the ermF, tetQ, nim, and cfxA drug resistance genes.

Despite rapidly diminishing treatment options for Neisseria gonorrhoeae and high levels of ciprofloxacin resistance worldwide, Norwegian guidelines still recommend ciprofloxacin as empirical treatment for gonorrhea. The present study aimed to characterize phenotypical and genotypical properties of N. gonorrhoeae isolates in Norway in 2009. All viable N. gonorrhoeae isolates (n = 114) from six university hospitals in Norway (2009) were collected, representing 42% of all notified gonorrhea cases. Epidemiological data were collected from the Norwegian Surveillance System for Communicable Diseases and linked to phenotypical and genotypical characteristics for each N. gonorrhoeae isolate. Resistance levels to the antimicrobials examined were: ciprofloxacin 78%, azithromycin 11%, cefixime 3.5%, ceftriaxone 1.8%, and spectinomycin 0%. The minimum inhibitory concentrations of gentamicin varied from 1.5 to 8 mg/L. Forty-one (36%) of the isolates were β-lactamase-producing, 17 displayed penA mosaic alleles, and 72 different N. gonorrhoeae multiantigen sequence types (ST; 37 novel) were identified. The most common ST was ST1407 (n = 11), containing penA mosaic allele. Four of these isolates displayed intermediate susceptibility/resistance to cefixime. The N. gonorrhoeae strains circulating in Norway were highly diverse. The level of ciprofloxacin resistance was high and the Norwegian management guidelines should promptly exclude ciprofloxacin as an empirical treatment option for gonorrhea.

The purpose of this study was to investigate the antigenic and biochemical characteristics, antibiotic susceptibility, and mechanisms for acquiring resistance of Haemophilus influenzae strains isolated in several Catalan hospitals, to determine the current situation regarding this microorganism in our area.
