Cefpodoxime proxetil, a relatively new broad-spectrum third-generaation cephalosporin, has very good in vitro activity against Enterobacteriaceae, Hemophilus spp. and Moraxella spp., including beta-lactamase producers and many strains resistant to other oral agents. It also has activity against Gram-positive bacteria, especially against streptococci. Cefpodoxime has no activity against enterococci. It is well tolerated and is one of the first third-generation cephalosporins to be available in oral form. While the compound has been used most widely in the treatment of respiratory and urinary tract infections, its utility has also been demonstrated in the treatment of skin structure infections, acute otitis media, pharyngitis, tonsillitis, and sexually transmitted diseases.

BACKGROUND. Ear, nose, and throat (ENT) problems are common in childhood and are important reasons to visit the general practitioner. OBJECTIVE. To examine trends in incidence rates, antibiotic prescribing, and referrals of five common ENT problems in children. DESIGN. Netherlands Information Network of General Practice (LINH), a nationally representative general practice database. Setting. A total of 50 000 children, aged 0-17 years, registered in Dutch general practice over the period 2002-2008. METHODS. Incidence rates were calculated and trends were analysed using linear regression analysis, with incidence rates per age group, proportion treated with antibiotics, and referrals as dependent variables and year of observation as independent variable. RESULTS. In general, incidence rates of acute otitis media, serous otitis, sinusitis, tonsillitis, and tonsil hypertrophy remained stable over the period 2002-2008. An increasing trend was observed for serous otitis media in children aged 0-4 years (RR = 1.04, p < 0.001). A decreasing trend was observed for sinusitis in children aged 5-11 and for tonsillitis in children aged 11-17 years (RR 0.99, p < 0.001 and RR 0.94, p < 0.001, respectively). Antibiotics were prescribed in 10-60% of the diagnoses. An increasing trend for antibiotic prescription was found for acute otitis media (beta = 0.07, p < 0.001), mainly on account of amoxicillin. Although antibiotic treatment of tonsillitis remained stable, pheneticillin prescriptions showed a downward trend (beta = -0.10, p < 0.001). First-choice antibiotics were prescribed in >80% of cases. CONCLUSIONS. This study showed remarkably stable trends in incidence rates, antibiotic prescribing, and referrals of common ENT problems. The low proportion of antibiotic treatment in ENT problems did not show negative consequences.

The palatine and nasopharyngeal tonsils (adenoids) are lymphoepithelial tissues located in strategic anatomical areas of the oral pharynx and nasopharynx. These immunocompetent tissues represent the first line of defense against ingested or inhaled foreign proteins such as bacteria, viruses, or food antigens. Accompanying the advances being made in the field of medicine today, the role of the tonsils in immunocompetence is becoming extremely important. Upper respiratory tract infections such as acute otitis media, acute rhinosinusitis and acute pharyngo-tonsillitis are diseases that occur with extremely high frequency, and the antimicrobial agents used to treat these diseases account for a large proportion of health care costs. The increasingly refractory nature of upper respiratory tract infections caused by drug-resistant bacteria has become a major worldwide concern. The elucidation of the immune functions of the tonsils and mucosal membranes of the upper respiratory tract is considered to have important significance. The tonsils are also considered to play an important role as one of the causes of sleep apnea syndrome, and have been reported to be intimately involved in the manifestation of IgA nephropathy and palmoplantar pustulosis, a kind of skin disorder. Interest has continued to grow in this symposium with each session ever since it was first held in Kyoto, Japan in 1987. Since then, the symposium has been held every 3-4 years; in Pavia in 1991, in Sapporo in 1995, in Ghent in 1999, in Wakayama in 2003, and in Siena in 2006. Since the 5th symposium in Wakayama, the topics were extended to mucosal barriers of upper airways including the mucosal immune system, innate immunity, and mucosal vaccine. Recent fine technologies and information on molecular biological approaches for upper airways will continue to advance our understanding of epidemiology, etiology, pathogenesis, diagnosis and management of tonsil-related disorders and various upper respiratory tract infections such as otitis media and rhinosinusitis. Moreover, in the era of drug-resistant microbes, we should exert more effort to develop powerful and effective mucosal vaccines against pathogens in upper airways.

This study investigates the use of antibiotics and prescribing patterns and identifies the antibiotics most frequently prescribed in public health units of Belo Horizonte, MG. The methods used were observational, cross-sectional study aimed at analyzing the consistency between a sample of medical records and antibiotic prescriptions dispensed during March 2002 in eleven public health units in Belo Horizonte, Minas Gerais, Brazil. Pediatrics showed the highest proportion of antibiotic prescribing among four specialties; amoxicillin was the most frequently prescribed antibiotic, followed by benzathine penicillin G, sulfamethoxazole/trimethoprim, and erythromycin. Upper respiratory tract infections, tonsillitis, acute otitis media and urinary tract infections were the diagnostic hypotheses most frequently recorded. Overall consistency between the recorded diagnostic hypotheses and the prescribed antibiotic was lower than 75%. The duration of the therapy prescribed varied largely and in approximately 10% of the prescriptions this information was lacking. Moreover, data on the patient such as age, body weight, co-morbidity, diagnostic hypotheses and adverse reactions, were systematically absent in the medical records. This study demonstrates the need for interventions in order to promote a more rational use of antibiotics.

Recurrent pharyngo-tonsillar infections caused by group A beta-hemolytic streptococci (GABHS) occur frequently in young children, and the treatment of these infections contributes substantially to the total current requirement for antibiotic prescribing. Our study goal was to assess through a retrospective observational analysis whether the administration of the oral probiotic, Streptococcus salivarius K12 (SsK12), could reduce the occurrence of GABHS pharyngo-tonsillar infections in children who had a recent history of recurrent episodes of these infections. Twelve primary care pediatricians identified, through their databases, a total of 130 children who had experienced recurrent GABHS pharyngo-tonsillar infections over a period of at least 6-12 months prior to their inclusion in the study. Of these children, 76 then undertook a 90-day program requiring once-a-day dosing with a commercially available (Bactoblis) lozenge containing SsK12. No probiotic supplement was given to the remaining 54 (control) children. Each subject was monitored for the occurrence of GABHS pharyngo-tonsillitis and also for acute otitis media, bronchitis, sinusitis, and bronchopneumonia for at least 12 months following their entry to the study. Even 9 months after the use of SsK12 had been stopped, the probability of new GABHS infections was significantly lower (P>0.001) when compared to the period before dosing commenced. When compared to the untreated children, those taking SsK12 appear to have had significantly fewer GABHS infections both during the 90-day period of prophylaxis and during the following 9 months (P<0.001). These observations are supportive of the use of probiotic SsK12 for the control of recurrent GABHS pharyngo-tonsillar infections in children, and as an associated benefit, the use of this probiotic could lead to reduced antibiotic consumption. Follow-up controlled prospective studies should now be initiated in order to further establish the efficacy of this newly emerging prophylactic strategy.

This study aims to assess prospectively whether there is an association between frequencies of upper respiratory tract infections (URTI) or asthma in early childhood and failed otoacoustic emission (OAE) screenings later in life. There are no clear recommendations for hearing testing following acute otitis media (AOM) infection. This is a retrospective, practice based chart review. Participants from a primary care setting were 517 pre-adolescent and adolescent children (49.9% female) (ages 10-21; mean, 15 y/o), who had presented with at least one specific bacterial URTI (AOM, Group A Streptococcus (GAS) tonsillitis, or Influenza) during childhood. Hearing testing was recorded incidentally at all subsequent routine health care maintenance visits (OAE hearing screen). Simple linear regression analyses were performed using R (v3.4.4). We found that number of episodes of AOM infections strongly correlated with number of failed OAE screenings later in life (F = 76.37; P = <0.001; R2 = 0.1279), while GAS (F = 1.859; P = 0.1733; R2 = 0.0016) or Influenza infection (F = 2.624; P = 0.1059; R2 = 0.0031) were not associated with failed OAE screening. Correlation between number of AOM infections and number of failed OAE screenings was not strengthened by presence of asthma. This study found evidence of an association between childhood history of AOM and failed OAE screenings in adolescence. Since this population may be at a higher risk for developing permanent or fluctuating hearing losses, further studies to clarify indications and timing of standard audiological testing among these children should be considered.
