Background and Aims: Healthcare for the increasing number of migrants in Europe, and particularly of unaccompanied minors (UMs) seeking asylum, has become a major challenge. We aimed to describe the health issues of UMs managed in a dedicated pediatric consultation service in a care center in Paris., Methods: All UMs attending a dedicated migrant medical consultation service in Robert Debré Hospital, Paris, France, were included in a single-center retrospective observational study from September 1, 2017, to September 30, 2018., Results: Out of the 107 UMs who were included, 87% had a health problem (n=93) and 52% had an infectious disease (n=56). The main infectious diagnoses were schistosomiasis (22%), latent tuberculosis (22%), intestinal parasitosis (16%), and chronic hepatitis B (8%). Posttraumatic stress disorder (PTSD) and overweight were common (35% and 20%, respectively). The median age was 15 years old (IQR, 14-16), the male/female ratio was 95/12. Most of the children were from sub-Saharan Africa (n=67), 46% had crossed Libya (n=49) and, when compared to the other migration routes, faced an increasing risk of violence (69%, p=0.04), imprisonment (53%, p=0.03), and forced labor (48%, p=0.02). The median duration of the trip before reaching France was 6 months (IQR, 2-13), the median time to consultation was 2 months (0-5) and was not associated with an increased risk of health problems. A total of 43 UMs were lost to follow-up., Conclusion: Health problems, particularly infectious diseases and PTSD, are common among UMs and should prompt an early medical consultation with psychiatric evaluation. Follow-up is problematic and could be improved by an on-line health book., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 French Society of Pediatrics.

Dengue is the arboviral disease that has massively spread in intertropical regions these past few years. The rise in imported cases of dengue and the rapid spread of the Aedes vector mosquitoes in continental France since 2004 explain the occurrence of indigenous dengue cases among the nonimmune population and points to an epidemic risk. Severe dengue cases are rare, but lethality is highest among children under 5 years of age. Like pediatricians in tropical regions, we must learn how dengue presents in metropolitan France and how it can be managed, and pay special attention to severe and potentially fatal forms. The epidemiological, pathophysiological, clinical, diagnostic, and therapeutic characteristics of dengue are presented herein., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Child travelers are numerous, exposed to the risk of diseases, both infectious and noninfectious, for which practitioners often lack experience. The assessment of febrile returning child travelers is becoming more frequent and challenging. The question of previous travel should be foremost in the checklist of the interview of any febrile child traveler, because this implies a possible tropical disease such as malaria that may be life-threatening. These need to be investigated and treated effectively and rapidly. There are highly contagious infections that could pose public health risks requiring implementation of hygienic and public health measures. A detailed immunization, medical, and travel history for exposure to infectious risks using geographic, seasonal, environmental, sociocultural, and epidemiological data are needed. Along with clinical examination and elementary first-line investigations, the history should guide second-line exams, which will provide the etiology and optimal treatment in approximately 75 % of cases. The majority of children will have a cosmopolitan infection that resolves spontaneously or is simple to treat. Malaria will need urgent and specific treatment. This article describes guidance on first-line evaluation and management of febrile child travelers as recommended in France., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Consultation of child traveler has two main objectives: to assess of health risk related to the child's health status and history and also the risk related to travel environment; to counsel and prescribe preventive measure to reduce these travel health risks. The evaluation is based on physical examination and a detailed interview including personal history and information regarding the regions of proposed travel. Up to date knowledge of the epidemiology of visited sites, preventive measures and presumptive treatment is required. Essential health recommendations include, in case of exposure, prevention of malaria, arthropod borned diseases and vaccine preventable diseases. For all destinations advice regarding prevention of diarrhea, accident risks and aggravation of preexisting chronic diseases is needed. Universal primary prevention counselling is valuable for all travellers regardless of their age. In the case of children, special attention must be given to food and water hygiene, sun and heat exposure, swimming risks and transports security measures. Evaluation of risk and health education take time and often several visits are needed to complete the immunization schedule before departure., (Copyright © 2012 Elsevier Masson SAS.

Use of topical insect repellent is an important component in prophylaxis of arthropod bite vector borne diseases. Topical insect repellent are used in a three part management regimen, along with impregnated clothing and mosquito netting. Parental training for efficacious and secure use of repellents for their children is essential part of a successful strategy to combat Lyme borreliosis, dengue fever, Chikungunya, West Nile virus infection and malaria, amongst children, according to local epidemiological risks. Rational repellent prescription for a child must take into account age, active substance concentration, topical substance tolerance, nature and surface of the skin to protect, number of daily applications, and the length of use in a benefit-risk ratio assessment perspective. The 4 currently repellents recommended by Whopes (Who) for their long lasting efficacy and patient tolerance are: 1) Citriodiol (PMD), 2) DEET, 3) Icaridine (KB3023), and 4) IR3535. In field trials the minimum required concentration of each four of these agents to be effective for 3 hours against most arthropods is 20% (in cream, roll-on or spray vehicle). Described side effects of these agents are mild, being limited to local irritative dermatitis and allergy. The risk of severe side effects has been related to DEET misused and neurotoxicity. The international recommendations concerning utilization of topical repellent amongst children for prophylaxis of arthropod borne diseases is concerning short term usage (several weeks). But the use of repellent is sub chronic or chronic amongst the majority of children living in subtropical regions where these vector borne diseases are endemic. And toxicity of topical repellent when used sub-chronically and chronically is not well studied in pediatric age groups. Taking into account these considerations, the current recommendations of the French Group of Tropical Paediatrics are to teach the parents of children who live in arthropod vector disease endemic regions to use topical insect repellent on their children with the recommended age related frequency in the following way: the use of topical repellent in infants above 6 months, once daily. Only in exceptional circumstances of severe arthropod exposure risk, their brief use in nursing infants as young as 2 months is acceptable, however with never more than 1 application daily. From ages 1 to 12 years, 2 applications daily may be safely used; 3 applications daily after 12 years old through adulthood.

Vector transmitted diseases are often a serious threat for child health, especially for children traveller in tropical regions. Few arthropod borne diseases are preventable by immunization or chimioprophylaxis. Prevention of most of them is based on personal protection against arthropod bites. The evidence of its efficacy has been established by the use of impregnated bed nets, impregnated clothes with permethrin or mosquito repellent which reduced significantly child malaria morbidity and mortality in endemic countries. These personal protective measures are able to minimize arthropod bites and prevent Chikungunya infection, dengue fever and Lyme disease. The choice of a repellent among the commercialised products need to be efficacy and safety evidence based. This article propose to raise this issue and to give pragmatic recommendations, with a focus to children below 30 months who are at a high toxicological risk. Severity of these diseases allowed to use potentially toxic repellents if misused.

Each year, half a million of children leave France to travel towards countries south or east of the European Union, sometimes in poor sanitary conditions. In order to propose essential or useful immunizations for these trips, the current synthesis will allow the practitioner to insure that the routine French immunization schedule has been followed, and to complete it if needed, to protect the child according to the epidemiological situation in the visited area, to try to reduce the limitations of the immunization of the traveler child. In case of emergency, or close departure, it may be useful to follow an accelerated schedule of the last minute, and, sometimes, to immunize traveler children with a chronic disease. Informations on Internet sites useful for the knowledge of current infectious risks in the destination country are also provided.

Context and Objectives: Imported P. falciparum malaria cases are rising in France reaching 1300 estimated children in 2000. Three years after the publication of therapeutic guidelines, the Groupe de Pédiatrie Tropicale conducted an observational survey in order to describe the practice of acute uncomplicated malaria treatments in children, to identify their limits and to make proposals to improve them., Methods: A self administrated questionnaire has been proposed to 29 pediatric wards declaring over 10 malaria cases in 2000. Questions were focused on treatment practices and monitoring of children diagnosed with acute uncomplicated malaria in 2002., Results: Twenty-six services, who treated more than 700 children, responded. Twenty-two on 26 services hospitalized systematically malaria cases. Mean duration of hospitalization was 2.2 days (S.D. +/- 0.9). First line treatment was halofantrine in 22 on 26 services and mefloquine in four services. A second halofantrine dose was given systematically at day 7 in three services. No clinical cardiac effects happened. Quinine was used in perfusion only in cases of gastric intolerance. Treatment failure has never been experienced in the 22 services using halofantrine and has been experienced at least once in two on four wards using mefloquine. Relapse occurred at least once in 19 on 22 wards treating with halofantrine., Discussion: Halofantrine with hospitalization is still the leading treatment of acute uncomplicated malaria in children in France. In spite of the absence of clinical cardiac incident, a second cure of halofantrine was not often used, exposing to a high rate of relapse. Mefloquine is three time more used than in 1997, in spite of its digestives side effects that can explain failures of treatment. When done, the systematic clinical and parasitological control confirms failures after mefloquine and the high incidence of relapse after one cure of halofantrine. Only used in case of severity or digestive disorders, quinine is a little less prescribed in acute uncomplicated malaria in 2001 than in 1997., Conclusions: The limitations of antimalarial drugs used in France in case of acute malaria argue for an improvement of protocols (systematic second reduced dose of halofantrine after day 7, mefloquine associated with antiemetic drug) and a systematic clinical and parasitological monitoring. As alternative, efficient combinations of antimalarial as first line treatment are needed in France.
