APPK is frequent among patients with CF and, thus, should be considered a sign of CF. APPK is underdiagnosed because physicians usually do not look for it. CF screening should be considered for any patient presenting with these symptoms, followed by genetic counselling if necessary.

WHAT'S KNOWN ON THIS SUBJECT: Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few singlecountry reports are available describing delivery of primary care to children with obesity. WHAT THIS STUDY ADDS:Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. abstract OBJECTIVE: To determine and compare attitudes, skills, and practices in childhood obesity management in 4 European countries with different obesity prevalence, health care systems, and economic situations. METHODS:A cross-sectional survey was distributed to primary health care providers from France, Italy, Poland, and Ukraine. The questionnaire was returned by 1119 participants with a response rate of 32.4%. RESULTS:The study revealed that most of the primary health care providers were convinced of their critical role in obesity management but did not feel sufficiently competent to perform effectively. The adherence to recommended practices such as routine weight and height measurements, BMI calculation, and plotting growth parameters on recommended growth charts was poor. Most primary health care providers recognized the need for continuing professional education in obesity management, stressing the importance of appropriate dietary counseling. CONCLUSIONS:The study underlines insufficient implementation of national guidelines for management of obesity regardless of the country and its health system. It also makes clear that the critical problem is not elaboration of guidelines but rather creating support systems for implementation of the medical standards among the primary care practitioners.

bCystic fibrosis (CF) is the most frequent lethal genetic disease in the Caucasian population. Lung destruction is the principal cause of death by chronic Pseudomonas aeruginosa colonization. There is a high prevalence of oropharyngeal anaerobic bacteria in sputum of CF patients. This study was carried out due to the lack of results comparing subgingival periodontal pathogenic bacteria between the oral cavity and lungs in patients with CF in relation with P. aeruginosa presence. Our first goal was to detect P. aeruginosa in oral and sputum samples by culture and molecular methods and to determine clonality of isolates. In addition, subgingival periodontal anaerobic bacteria were searched for in sputum. A cross-sectional pilot case-control study was conducted in the CF Reference Center in Roscoff, France. Ten CF patients with a ⌬F508 homozygous mutation (5 chronically colonized [CC] and 5 not colonized [NC]) were enrolled. P. aeruginosa was detected in saliva, sputum, and subgingival plaque samples by real-time quantitative PCR (qPCR). Subsequently, periodontal bacteria were also detected and quantified in subgingival plaque and sputum samples by qPCR. In CC patients, P. aeruginosa was recovered in saliva and subgingival plaque samples. Sixteen P. aeruginosa strains were isolated in saliva and sputum from this group and compared by pulsed-field gel electrophoresis (PFGE). Subgingival periodontal anaerobic bacteria were found in sputum samples. A lower diversity of these species was recovered in the CC patients than in the NC patients. The presence of the same P. aeruginosa clonal types in saliva and sputum samples underlines that the oral cavity is a possible reservoir for lung infection.

Implementing oprL and gyrB/ecfX qPCR in the management of patients with CF allowed earlier detection of first P. aeruginosa lung positivity than culture alone.
