Counselling on sun protection, a survey of French paediatricians.

BACKGROUND: High sun exposure during childhood is an important risk factor for skin cancers at adulthood. Paediatricians are first in line to provide sun protection (SP) information. OBJECTIVE: To describe paediatricians' attitudes towards SP counselling and compare French and American paediatricians' behaviours. METHODS: Methodology used by the American Academy of Pediatrics in 2001. Validation of the French version of the questionnaire. Survey of all 1108 paediatrician members of the Association Française de Pédiatrie Ambulatoire (AFPA) RESULTS More than 90% of paediatricians agreed that skin cancers are a Public Health concern, that preventing episodic high sun exposures during childhood would reduce the risk of adult melanoma, and that it is a paediatrician's role to educate parents/patients on SP. Three quarters reported counselling all of their patients. The most important SP recommendation was to avoid sun during peak hours, followed by sunscreen use. Only 48.3% of paediatricians rated SP as very important to their patients' health, at the 8th rank among selected preventive care topics. The most frequently identified barrier to SP counselling was cost of sunscreens followed by lack of sufficient time. CONCLUSIONS: The majority of paediatricians believe that prevention of skin cancers is a worthy issue and it is their role to educate patients, but less than half of them consider SP as an important topic among selected preventive care issues. Although paediatricians seem to know SP measures well, their (counselling?) seems to respond to patients' preoccupations more than to expert recommendations. French and American behaviours show some major differences.

Impact of antimicrobial therapy on nasopharyngeal carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis in children with respiratory tract infections.

We conducted a multicenter prospective study to document changes in nasopharyngeal carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis during antibiotic therapy. A cohort of 629 children with respiratory tract infections underwent nasopharyngeal sampling before and after antibiotic treatment. Susceptibility testing, serotyping, arbitrarily primed polymerase chain reaction, and pulsed-field gel electrophoresis were used to compare pretreatment and posttreatment strains of S. pneumoniae. A significant decrease in carriage of all 3 species (especially S. pneumoniae and B. catarrhalis) was recorded. The increase in the proportion of penicillin-resistant pneumococci (PRP; 66% vs. 44%) was due to the decreased carriage of penicillin-susceptible pneumococci (71 of 629 vs. 176 of 629). The risk of PRP carriage in a given child did not increase. None of the children was found to harbor genetically related strains with increased minimum inhibitory concentrations. Given the multiple resistance of PRP, beta-lactam antibiotic therapy also increased the incidence of macrolide-resistant strains, whereas macrolides selected both macrolide- and penicillin-resistant strains.

One dose ceftriaxone vs. ten days of amoxicillin/clavulanate therapy for acute otitis media: clinical efficacy and change in nasopharyngeal flora.

OBJECTIVE: To compare the efficacy and the safety of a single intramuscular dose of ceftriaxone, 50 mg/kg, vs. a 10-day course of amoxicillin/clavulanate (amox/clav) therapy, 80 mg/kg/day of amoxicillin: 10 mg/kg/day of clavulanate in three divided doses, in children with acute otitis media (AOM) and to evaluate the changes in nasopharyngeal flora after treatment. METHODS: In a prospective, comparative, open randomized, multicenter trial, children were scheduled to return for visits on Days 12 to 14 (main end point) and Days 28 to 42 after the beginning of treatment for AOM. A nasopharyngeal swab for bacterial culture was obtained before the treatment and at Days 12 to 14. RESULTS: Between February, 1995, and May, 1996, 513 children with a mean age of 14.2 +/- 6.7 months were enrolled. All the patients were evaluable for the safety and intent-to-treat analyses and 463 for the per protocol efficacy. At Days 12 to 14 clinical success was obtained in 186 of the 235 children (79%) given ceftriaxone and in 188 of the 228 children (82.5%) treated with amox/clav. Among the patients with clinical success on Days 12 to 14, the success was maintained at Days 28 to 42 for 108 of 183 (59%) patients in the ceftriaxone group and 103 of 187 (55%) patients in the amox/clav group. Before the antibiotic treatment the percentages of children carrying Streptococcus pneumoniae (59.1%), Haemophilus influenzae (39.4%), Moraxella catarrhalis (55.7%) and the rate of penicillin-resistant S. pneumoniae (52.2%) were comparable between the 2 groups. At Days 12 to 14 the carriage of S. pneumoniae and M. catarrhalis was significantly different between the patients treated with ceftriaxone, 43.9 and 42.2, respectively, and the patients treated with amox/clav, 17.4 and 11.1%, respectively. Among the children carrying S. pneumoniae at Days 12 to 14, the percentage of penicillin-resistant strains reached 63.4% in the ceftriaxone treatment group and 83.0% in the amox/clav treatment group, (P = 0.02). Adverse events (mainly diarrhea) related to the study medication were reported more frequently (P < 0.0001) in the amox/clav treatment group. CONCLUSIONS: In an area with a high rate of penicillin-resistant S. pneumoniae, a single dose of ceftriaxone is as efficient as a 10-day course of amox/clav in the treatment of AOM in young children. There was for the two regimens an increased rate of penicillin-resistant strains among the pneumococci carried, whereas the chance for a child to carry a penicillin resistant S. pneumoniae did not increase after treatment.
