[The emergency department: an appropriate place for identifying troubled teens]. / Les urgences, un lieu de repérage des adolescents en difficulté

OBJECTIVES: The main objective of this study was to estimate the prevalence of psychological distress among adolescents seen in emergency departments, and the secondary objective was to highlight their main reasons for consulting. METHODS: Cross-sectional study in three multicenter emergency departments receiving adolescents in Île-de-France conducted in 2010. All adolescents completed a questionnaire including the ADRS (Adolescent Depression Rating Scale, a screening questionnaire for depression) and a series of questions relating to somatization and risk behaviors. RESULTS: The study included 346 adolescents, 320 of which were fully analyzed. The ADRS score was considered normal (score < 3) for 70.6% of the sample (n = 226), 19.4% of adolescents (n = 62) had moderate depressive symptoms (3 ≤ score < 6), and 10.0% severe depressive symptoms (score ≥ 6) (n = 32). The majority of patients consulted for trauma and less than 10% for acute psychiatric problems; 17% of adolescents who came to the emergency department for a nonpsychiatric reason had an ADRS ≥ 3, i.e., with mental distress. CONCLUSION: The routine use of a self-administered questionnaire in the emergency services could identify adolescents with moderate to severe depressive symptoms.

Simultaneous determination of Solvent Yellow 124 and Solvent Red 19 in diesel oil using fluorescence spectroscopy and chemometrics.

Differences in tax levels for diesel oil stimulate the illegal removal of characteristic diazo compounds purposely added to designate its possible usage. In order to reduce the losses in the national income, there is a strong need to develop a sensitive and cost-effective analytical procedure for the detection of this illegal action. In this study, we describe a novel analytical approach for a qualitative and quantitative determination of two diazo compounds (Solvent Yellow 124 and Solvent Red 19) that are usually added to diesel oil. The methodology proposed combines the use of excitation-emission matrix fluorescence spectroscopy as an analytical technique and partial least squares regression as a multiple modeling tool. With this new methodology, relatively low root mean square errors of prediction (for independent set of test samples) that are equal to 0.223 for Solvent Red 19 and 0.263 for Solvent Yellow 124, were obtained and the results were stable, which were indicated by an analysis performed after 48 and 96 h. The methodology is also nondestructive and allows for (i) simultaneous detection of diesel oil additives, (ii) determination of satisfactory limits of detection (0.048 and 0.042 mg L(-1) for Solvent Red 19 and Solvent Yellow 124, respectively), and (iii) obtaining of considerably low relative standard deviations of 2.33% for Solvent Yellow 124 and of 3.23% for Solvent Red 19 in comparison with the existing norm level.

[Rapid malnutrition in patient with anorexia nervosa: experience of a general pediatric department]. / Dénutrition rapide au cours de l'anorexie mentale : expérience d'un service de pédiatrie générale.

OBJECTIVE: Rapid undernutrition in patients with anorexia nervosa can compromise vital functions, notably due to cardiac complications. The aim of this study was to analyze the clinical parameters of anorexic patients, hospitalized for substantial weight loss, in a general pediatric inpatient unit, in order to determine which parameters should be tested by the medical doctor. POPULATION AND METHODS: We performed a retrospective study on 20 consecutive patients (18 girls), median age of 13.75 (+/-2.3) years, admitted for the first time in our pediatric inpatient unit for anorexia nervosa. RESULTS: Symptoms evolved for a median duration of 11.5 (+/-10.2) months before admittance and was shorter for the youngest patients (r = 0.42, p = 0.067). The mean BMI was 13.3 (+/-0.6) kg/m(2) (-3.0+/-1.2 Z-score) and was inversely correlated with serum creatinine levels (74+/-15 micromol/l) (r = 0.44, p < 0.05). The mean BMI variation between the beginning of the disease and hospitalization (Delta BMI) was-3.5 Z-score and was correlated to low systolic blood pressure (r = 0.45, p< or =0.05) and the presence of a pericardial effusion at admittance (r = 0.45, p < 0.05). Complete blood count, electrolyte balance and the serum phosphorus levels were normal except in 1 case. Mean serum glucose was 3.5+/-1.2 mmol/l. At admittance, an electrocardiogram, performed for 16 patients, showed sinusal bradycardia without conduction impairment. Enteral nutrition was necessary for 14 patients (70%) for a mean duration of 18.1 days (range, 6-56 days). The mean weight gain was 3.1+/-2 kg and was inversely correlated to the BMI at admittance (r = 0.49, p < 0.05). CONCLUSION: Medical supervision of undernutrition tolerance during anorexia nervosa is above all clinical, as hematological and biological parameters remain normal for a long time. The cardiac complications found in our study appeared to be more related to the rapid rate of weight loss than to the amount of weight loss itself.

[Diagnostic value of the SHAPE questionnaire in recognition of the hyperventilation syndrome in children: a pilot study]. / Valeur diagnostique du questionnaire SHAPE pour le syndrome d'hyperventilation de l'enfant : étude pilote.

OBJECTIVE: Determination of a diagnostic scoring method for hyperventilation syndrome (HVS) in children and proposal of a simplified questionnaire. METHOD: We used the main clinical signs of HVS in children and adolescents identified in a previous study and classified them according to their odds ratios (OR). The intensity of each sign, measured using a visual analogic scale in the previous study, led us to analyze several scoring methods, with a breakdown between major and minor signs according to their OR. Building receiver operating characteristics (ROC) curves allowed us to choose the best diagnostic combination. RESULTS: A sample of 85 children and adolescents aged from 7 to 20 years (mean age, 11.9 years) was tested. This sample comprised 45 children with isolated HVS or HVS associated with asthma and 40 controls, with asthma but without HVS or attending our emergency unit after trauma. Seven respiratory signs and 10 nonrespiratory signs were selected. For each scoring method, a significant difference was observed between HVS and non-HVS patients. The most suitable area under the curve (0.934) and the best combination between specificity and sensitivity (Sp=0.90 and Se=0.82) were obtained when the scoring method was 0,3,6 for major signs, and 0,1,2 for minor signs, according to perceived intensity of each sign ("never or almost never", "sometimes" or "often or very often"). CONCLUSION: Since no gold standard is available to confirm the diagnosis of HVS in children, we propose using a simplified questionnaire composed of 17 items to compute a diagnostic score. The questionnaire will be validated shortly in a new prospective study.

[Value of a new thickened formula in infants with regurgitations]. / Intérêt d'une nouvelle préparation infantile dans la prise en charge des régurgitations du nourrisson.

OBJECTIVES: The purpose of this open multicenter study was to evaluate the value of a new starch-thickened formula in infants with regurgitations in ambulatory pediatric practice. POPULATION AND METHODS: The study population comprised full-term infants with an age at inclusion of 1-90 days, who were bottle-fed and presented regurgitations. The formula tested was an infant formula-thickened with starch (2g/100mL). The primary endpoint was the frequency of bottles regurgitated, expressed in percentage of meals per day after 15 days of feeding with the preparation studied. Secondary endpoints were the assessment of regurgitations using the Vandenplas' score, as well as the daily increase in weight, height, and cranial circumference, overall and gastrointestinal tolerance, and formula acceptability. RESULTS: Sixty-four infants presenting regurgitation were included. The frequency of bottles regurgitated estimated at 80.3% at inclusion significantly decreased at D3, D15, and D30 to 40.1, 40.2 and 37.2% (P<0.0001), respectively. Thirty percent of infants did not present regurgitations at all at D30. Similarly, a significant decrease in the Vandenplas' score was observed from 1.9 at D0 to 0.9 at D30 (P<0.0001). Infant growth was similar to the French and European growth curves. CONCLUSION: The results showed rapid and lasting improvement in decreasing the frequency of feeding-bottles regurgitated by 50% from the first 3 days of using this new starch-thickened formula (2g/100mL). These satisfying results encourage the use of the tested formula in cases of infant regurgitation, in line with the European Society of Gastroenterology, Hepatology and Nutrition (ESPGHAN) recommendations.

[A diagnostic questionnaire for the hyperventilation syndrome in children]. / Elaboration d'un questionnaire diagnostique du syndrome d'hyperventilation chez l'enfant.

INTRODUCTION: Intensive efforts should be made to diagnose the hyperventilation syndrome (HVS) at an early stage as this will prevent stigmatisation and reinforcement of symptoms. It will also prevent children from undergoing unnecessary medical examinations and treatment. A diagnostic questionnaire should be useful for this purpose. METHODS: We administered a questionnaire with 16 respiratory symptoms and 23 non respiratory symptoms to 25 children with HVS alone, 20 with asthma and HVS, and two control groups: 20 children with asthma without HVS and 20 presenting with trauma. For each symptom a visual analogue scale (VAS) was completed. The symptoms for which the mean VAS values were significantly different between the children with HVS and the controls were subject to principal component analysis after varimax rotation with Kaiser normalisation. RESULTS: There was no significant difference in symptoms between HVS children with or without asthma. The five major respiratory symptoms were: throat-clearing, sniffing, difficulty in breathing in, sighing and yawning. The combined sensitivity of those symptoms was 99%, the combined specificity 24%. The five major non-respiratory symptoms were: anxiety, difficulty in going to sleep, general fatigue, abdominal pain, and joint pains. The combined sensitivity of those symptoms was 99%, the combined specificity 36%. CONCLUSIONS: We performed a simplified diagnostic questionnaire for HVS in healthy and asthmatic children and found 5 respiratory and 5 non-respiratory symptoms of significance.

[Evaluation of a formula with low protein content and supplemented with probiotic agents after breast milk weaning]. / Evaluation d'une préparation pour nourrissons à teneur réduite en protéines et enrichie en probiotiques, en relais de l'allaitement maternel.

UNLABELLED: Besides assuring growth and development in early infancy, human breast milk plays a key role in preventing infections, in particular by favouring the growth of bifidobacteria. The development of infant formulas containing probiotic agents consequently represents a significant advance in the provision of an optimal alternative to breast feeding when this is not feasible. A further concern is to avoid an excessively high protein content relative to breast milk, potentially favouring obesity in later life. OBJECTIVES: The objective of this open Multicenter comparative study was to demonstrate that a new infant formula, characterized by a reduced protein content and the presence of a probiotic agent, was as effective as conventional formulas in assuring growth during the first months of life. POPULATION AND METHODS: The study population comprised full-term healthy infants with an age at inclusion of 1-28 days, whose mothers no longer wished to continue breast feeding or were unable to breast feed. The test formula (GE), enriched with Bifidobacterium lactis, had a protein content of 1.5 g/100 ml. The primary end point was daily weight gain from day 0 to day 90. Secondary end points were daily increase in height and cranial circumference, overall and gastrointestinal tolerance and formula acceptability. A total of 203 infants were included in the analysis, 117 receiving GE and 86 the formula habitually prescribed by the paediatrician. RESULTS: Daily gains in weight, height and cranial circumference did not differ significantly between the groups. The rates of overall and gastrointestinal adverse events were comparable in the two groups and the acceptability of GE was consistently good, similar to that of the standard formulas. CONCLUSION: The results of this study demonstrated that the new probiotic infant formula GE has equivalent efficacy to conventional formulas in achieving growth in early infancy, and is well tolerated.

[Early discharge from the maternity ward: telephone survey about the availability of private-practice and public health pediatricians in Ile-de-France]. / Disponibilité des pédiatres libéraux et communautaires en Ile-de-France après une sortie précoce de maternité.

OBJECTIVES: To assess the possibility and time period within which a mother and her newborn can consult a pediatrician after their early discharge from the maternity ward. METHODS: In May 2004, 2 investigators presenting themselves as mothers just discharged from the maternity ward, called pediatricians' offices and public infant cliniques (PMI centers) in the Paris metropolitan region, to request appointments. RESULTS: Of 99 pediatricians' offices contacted, 89 (89%) offered appointments, for an average of 4.4 days later. Of the 93 PMI centers contacted, 55 (59%) offered appointments by telephone, with a mean waiting time of 18 days. CONCLUSION: This study, conducted in the spring of 2004 in the Paris metropolitan region, showed that private-practice pediatricians are capable of taking over management of newborns rapidly after early discharge from the maternity ward. It is more difficult to make appointments by telephone with PMI centers, which operate differently, and the delay is substantially longer. We underline that these results observed in a region with a high density of pediatricians and during a favourable period for managing appointments. Further studies are needed in other regions and at different periods. The management of newborns after early discharge from the maternity ward should be actually throught the arising development of health networks.

[The pediatrician's waiting room: a place for health education?]. / La salle d'attente du pédiatre: lieu d'éducation pour la santé?

OBJECTIVES: To assess the presence and impact of health education messages in pediatricians' waiting rooms. METHODS: In September 2001, 81 pediatricians completed a questionnaire about the furnishings and equipment in their waiting rooms. They also distributed a questionnaire about waiting room health education messages to parents, to be completed at home. RESULTS: The analysis considered 1830 questionnaires. Health education messages were posted in 91% of the waiting rooms and most frequently concerned children's accidents, vaccines, hygiene and nutrition. The best topics that the parents remembered involved child neglect, antibiotic therapy, AIDS and other sexually transmitted diseases, and nutrition. Although memorization of the messages was not influenced by duration of the wait, it was higher among parents who had previously visited the pediatrician. These messages led 14% of the parents to discuss them spontaneously with their pediatrician. CONCLUSION: Health education messages are posted in nearly all the waiting rooms studied; parents remember them in a variable and rather inexplicable order. Posting these messages demonstrates the pediatricians' willingness to be involved - beyond the simple consultation - in the health education of children and families. Identifying the real impact of these messages would require further study.

Respiratory development of 5- to 6- year-old children experiencing a first bronchiolitis episode before age one.

BACKGROUND: The relationship between early infections due to respiratory syncytial virus (RSV), particularly bronchiolitis in infancy, and the subsequent development of asthma, bronchial hyper-responsiveness, and/or other allergic manifestations, seems increasingly certain, even if the mechanisms involved are not yet quite clear. OBJECTIVES: The objectives of this work were to determine the prevalence of, and risk factors for, asthma and allergy in 5 to 6 year-old children who five years previously, had experienced their first episode of bronchiolitis before the age of twelve months, and to define the possible effect of the age at which the bronchiolitis occurred on the subsequent development of asthma. METHOD: A retrospective cohort survey was conducted, based on the registers of two hospital paediatric emergency units (Unit A: the Ambroise Pare teaching hospital at Boulogne, France and unit B: the General Hospital of Cherbourg, France). The cohort comprised 5-6 years old children who had consulted or been admitted to emergency unit A or B between October 1993 and March 1994 for a first attack of bronchiolitis before the age of 12 months. RESULTS: One hundred and twenty eight children were included in the two centres (centre A: 78; centre B: 50). A familial history of allergy was found in 92 children (71.8%). Fifty-two (40.6%) were exposed to tobacco smoke. One hundred and five children (81.2%) had been hospitalised during the first episode of bronchiolitis, but none had been placed in intensive care. Their mean age at admission was 5.1 months, and 29 children were less than three months old. Ninety seven children (75.8%) had experienced at least one episode of wheezing at some time of their life. In the twelve months before the telephone interview, 40 children (31.3%) had had at least one such episode, 47 (36.7%) an attack of asthma, 32 (25.0%) wheezing after an effort, 43 (39.4%) a dry cough at night, 52 children (40.6%) had exhibited allergic rhinitis signs, and 32 (25.0%) eczema. Among the 47 children who had experienced at least one attack of asthma during the previous twelve months, 27 (57.4%) had a history of familial asthma (p<0.04). This was the only significant relationship observed in this study with regard to risk factors for asthma. No relationship was observed between asthma or recent wheezing on the one hand, and on the others age less than three months during the first bronchiolitis episode (p=0.6), initial hospital admission (p=0.6) tobacco smoke exposure (p=0.27), sex (p=0.10) or day care management until age three (p=0.73). DISCUSSION: This study showed a high prevalence of asthma and other allergic manifestations in children who five years previously, had experienced their first bronchiolitis episode before the age of twelve months. The only risk factor for asthma or chest wheezing identified in this study was a familial history of allergy. These data support the idea that for most children, early acute bronchiolitis, even if severe, is a transient event, with no or very few consequences in the middle or long term. Nevertheless it may be the expression of an interaction between viral infection and atopic familial predisposition leading to lasting bronchial hyper-responsiveness.

[The cost of Mohs micrographic surgery for basal cell carcinoma. The Ambroise Paré hospital's experience (Boulogne, France)]. / Coût de la chirurgie micrographique de Mohs dans les carcinomes basocellulaires. L'expérience de l'hôpital Ambroise Paré (Boulogne, France).

OBJECTIVE: Mohs'micrographic surgery is generally considered as the best procedure for the treatment of difficult basal cell carcinomas. It is supposed to be costly, but an economic evaluation, with a cost-outcome analysis, is necessary to estimate the actual contribution of this procedure in skin cancer treatment, in comparison with the reference procedure, i.e. traditional surgical excision. Our aim was to evaluate the actual cost of Mohs'surgery applied on basal cell carcinoma treatment in France. METHODS: The charts of 97 patients treated by Mohs'surgery between january 1997 and july 2001 in a teaching hospital near Paris (Ambroise Paré hospital, Boulogne), where Mohs'surgery is exclusively performed in France, were reviewed. Direct costs were derived from resource utilization of staff and material required for Mohs'surgery, estimated by a micro-costing method. Indirect costs and total costs were then calculated. RESULTS: When adding surgery and pathology facility costs, mean direct and total costs per basal cell carcinoma were 776.0 (range: 538.4-1273.9), and 1014.6 Euros (range: 777-1512.4), respectively. When including costs of diagnosis, the average total cost per procedure was 1084.3 Euros. DISCUSSION: These costs appear higher than those obtained with other methods of valuation of hospital costs used in France, but they are slightly lower than those found in the literature. The next stage will be to estimate, in the same way, the cost of traditional surgical excision for the same type of lesions, and to calculate the incremental cost-effectiveness ratio between the two procedures, with rate of recurrence at five years as the effectiveness outcome.

Home delivery of an injury prevention kit for children in four French cities: a controlled randomized trial.

OBJECTIVES: Home delivery of counselling and safety devices to prevent child injuries could help parents to adopt safe behaviour. The aim of this study was to test a safety kit designed and used in Quebec (Canada). DESIGN AND SUBJECTS: One hundred families from four towns in the Paris suburbs were visited at home by nurses or doctors when their child reached 6-9 months. Selection criteria were: primipara, medical problem, psychological, and/or socioeconomic difficulties. INTERVENTIONS: During the first visit, 50 families (group 1) received counselling and a kit including preventive devices and pamphlets about indoor injuries and ways to avoid them. The other 50 families (group 2) received counselling but not the kit. A second home visit was made 6-8 weeks later. MAIN OUTCOME MEASURES: The number of safety improvements was calculated 6-8 weeks after a first home visit. Perceived usefulness of the kit was collected from families and from interviewers. RESULTS: Between the first and the second visits, safety improvement was significantly higher in the group with the kit. This was mainly related to the risk of fall (p<0.02), fire and burns (p<0.001), poisoning (p<0.01), and suffocation (p<0.001). For improvement related to devices provided in the kit, the difference between the groups was significant: 64.4% improvement in group 1 versus 41.2% in group 2 (p<0.01). The relative risk (RR) of safety improvement between groups was 1.56 (95% confidence interval (CI) 1.35 to 1.80). Even for improvements not related to the kit the difference remained significant: 31.2% in group 1 versus 20.2% in group 2 (p<0.05); RR = 1.54 (95% CI 1.22 to 1.93). CONCLUSION: Routine home visits by social services offer a good opportunity to tackle child injury prevention. Free delivery of prevention kits and counselling allow families to modify their behaviour and homes so as to reduce risks.

[Evaluation of the effectiveness of an injury prevention kit delivery for toddlers in four French cities]. / Evaluation de l'efficacité de la remise d'une trousse de prévention des accidents domestiques de jeunes enfants: essai d'intervention dans quatre communes des Hauts-de-Seine (France).

BACKGROUND: The home delivery of counseling and devices intended to prevent child injuries could help parents to adopt safe behavior more efficiently. The aim of the present study was to adapt and test in France a safety kit designed and used in Quebec (Canada). The intervention program (kit delivery and counseling) was assessed by measuring 6 to 8 weeks after a first home visit the percentage of safety changes adopted by the families included in the survey, compared with the pre-intervention situation; and by evaluating the satisfaction of families with their participation in the survey, and the satisfaction of nurses with the use of this new tool. POPULATION AND METHOD: One hundred families from 4 towns in the Hauts-de-Seine department in the Paris suburbs (Boulogne, Chaville, Sèvres, Ville d'Avray) were selected by the social services for home visits by nurses or doctors, when their child reached the age of 6 to 9 months. Selection criteria were usually primipara, medical problem, psychological and/or socio-economic difficulties. During the first visit, 49 families (group 1) (1 family lost for follow-up) received the usual informative and preventive counseling, and a kit including preventive devices and pamphlets about indoor injuries and ways of avoiding them. The other 50 families (group 2) received counseling but not the kit. Between 6 and 8 weeks later, a second home visit was paid to all selected families. RESULTS: Between the first and the second visits, the percentage of safety improvement was significantly higher in group 1 (with the kit) than in group 2 (without the kit). This improvement mainly related to the risk of fall (P < 0.02), fire and burns (P < 0.001), poisoning (P < 0.01) and suffocation (P < 0.001). When the analysis was focused on safety improvement related to devices provided in the kit, the difference between the 2 groups was significant: 67.8% of safety improvement in group 1 vs 38.1% in group 2 (P < 0.001). The relative risk (RR) was 1,78 (95% confidence interval (CI): 1,18-2,68). Even for items not related to the devices provided, the difference remained significant: 48.6% in group 1 vs 28.8% in group 2 (P < 0.001); RR =1,31 (95% CI: 1,23-1,40). The perceived usefulness of the kit was discussed in a focus group with all nurses and doctors. On the whole, the judgment was very positive, mainly because the kit facilitated the introduction of the notion of accident prevention in the discussion at home. CONCLUSION: As in the canadian survey, our results indicate that routine home visits by the social services offer a good opportunity to introduce the subject of child injury prevention. Free delivery of prevention kit and simple counseling allow often deprived families to modify their behavior and to arrange their apartments so as to reduce risks.

Implementation of a system of surveillance of childhood injuries involved in a Safe Community program: the example of Boulogne-Billancourt (France).

OBJECTIVES: To provide precise information about child injuries, intended to promote preventive actions, in keeping with the general pattern of a Safe Community program implemented in Boulogne-Billancourt (France) since 1997. METHODS: Information about children under 16 injured in the city of Boulogne-Billancourt and its surroundings, are extracted in a database. DISCUSSION: The Boulogne-Billancourt database is the first permanent and specific childhood injury surveillance system in France integrated in a "Safe Community". It may constitute an "alarm system" by allowing rapid implementation of preventive action. The final evaluation of the collected data will be performed at the end of the program (after five years).

[Frequency of childhood injuries: first results of the Boulogne-Billancourt registry]. / Analyse des accidents de l'enfant: premiers résultats de l'Observatoire de Boulogne-Billancourt.

BACKGROUND: Boulogne-Billancourt database is in France the only permanent and specific childhood injury surveillance system. Integrated in an safe community program designed by the World Health Organization (WHO), the aims of a local database are to provide precise information intended to implement prevention actions. METHOD: All children less than sixteen years old living in Boulogne-Billancourt, victims of injuries occurring in that town, and requiring hospital care, are targeted. RESULTS: Two thousand five hundred and eighty accidents have been computed between 1(st) January 1998 and 31 December 1999, i.e. an average annual incidence of 79.7/1000 children. As in other similar databases, domestic accidents are prevalent in the average (40%), even though after five years old school injuries become the most frequent ones (36%). Falls are the main mechanism involved in injury at any age (44 to 54%). Distribution of other mechanisms varies with respect to age: foreign body prevalence is maximum between one and four (2.5%), struck-collisions (38%) between ten and fifteen years old. A significant increase of falls involving roller-skates or skateboards has been observed between 1998 and 1999 (3.8% versus 1.1%, p<0.001). Predominanting injury causes are contusions (38%), mainly head trauma (10%), open wounds (16%), fractures (10%), and sprains (6%). Two hundred and twenty four injuried children have been admitted in 1998, 205 in 1999, i.e. respectively 13.8/1000 and 12.7/1000 children dwelling in Boulogne. Overall recurrence rate is 32%, reaching 47% after eleven years old. A significant relationship has been observed between injury recurrence and problems related to education (odds ratio: 2.95; 95% CI: 1.75-5.00), atypical parenting situation (odds ratio: 1.70; 95% CI: 1.20-2.30), and family discord (odds ratio: 1.62; 95% CI: 1.05-2.50). Household accidents are the most avoidable ones in parents'opinion. This is not the case for road-traffic accidents, given evidence of the lack of means of protection observed in bicycle injuries. CONCLUSION: In spite of methodological issues such as control of exhaustivity of data, or difficulties to maintain a long-term surveillance sytem, this project worth carrying on with regard to provided information and usefulness for prevention. Other similar community experiences should be implemented with the aim of setting up a national-wide surveillance system, based on an homogenous data collection.
