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.

Insecticide resistance in head lice: clinical, parasitological and genetic aspects

Insecticide treatment resistance is considered to be a major factor in the increasing number of infestations by head lice. The large insecticide selection pressure induced by conventional topical pediculicides has led to the emergence and spread of resistance in many parts of the world. Possible mechanisms of resistance include accelerated detoxification of insecticides by enzyme-mediated reduction, esterification, oxidation that may be overcome by synergistic agents such as piperonyl butoxide, alteration of the binding site, e.g. altered acetylcholinesterase or altered nerve voltage-gated sodium channel, and knockdown resistance (kdr). Clinical, parasitological and molecular data on resistance to conventional topical pediculicides show that treatments with neurotoxic insecticides have suffered considerable loss of activity worldwide. In particular, resistance to synthetic pyrethroids has become prominent, probably because of their extensive use. As other treatment options, including non-insecticidal pediculicides such as dimeticone, are now available, the use of older insecticides, such as lindane and carbaryl, should be minimized, owing to their loss of efficacy and safety concerns. The organophosphorus insecticide malathion remains effective, except in the UK, mostly in formulations that include terpineol.

Dermatological emergencies: a comparative study of activity in 2000 and 2010

BACKGROUND AND OBJECTIVE

Studies of dermatological emergencies (DE) are few. We evaluated the activity in our DE unit in a 1-month retrospective study and compared the results with a similar study performed in the same department in 2000.

METHODS

We reviewed the charts of all outpatients seen in the DE unit in January 2010, collecting data on age, sex, place of residence, referral mode, day and hour of consultation, true emergency or non-emergency, diagnosis and follow-up.

RESULTS

In January 2010, we serviced 605 patients (58% males, mean age 40 ± 21 years), 21% more than in 2000; 43.5% were seen during off-duty hours vs. 49% in 2000 (P = 0.066), 49% were considered true emergencies vs. 43% in 2000 (P = 0.046), and 14% were referred by a physician vs. 23% in 2000 (P = 0.0001). In total, 35.2% of cases were infectious dermatoses in 2010 vs. 29% in 2000 (P = 0.026). Other diagnoses were eczema, urticaria and drug-related eruptions. Follow-up was suggested to 53.3% of the patients.

CONCLUSIONS

Our DE unit satisfies a genuine need. Its activity increased over 10 years, most likely because of the decrease in the number of dermatologists in France. Although our results are close to those reported in the literature, comparison with previously published studies is difficult because of the heterogeneity of the definition of DE.
