Based on a clinical case, this work aims to illustrate the multiple dimensions and modalities of psychological support in humanitarian work. It  also shows the importance and relevance of implementing a transcultural approach when dealing with complex trauma and traumatic bereavement among refugees and asylum seekers in an emergency context.

As part of a clinical practice which aims to alleviate the psychological suffering of children in situations of migration and/or uprooting, a discussion can be undertaken regarding the cultural aetiologies of migrant families whose children present autism spectrum disorders. The transcultural context enables families to travel between worlds as well as share their collective imagination regarding psychological suffering using graphic expression and narrative elements.

At the \"Maison de Solenn\", the role of the nurse is complex and plural. One of our main missions is to receive healthcare demands, to evaluate their pertinence and to direct them, if necessary, towards more adapted structures or professionals. This reception can be done by telephone or directly on site. The nurse must also point out the institutional framework for any follow-up undertaken in the structure. She is also responsible for accompanying the patient and the family to the various care providers. This welcome and support nursing role exists in more specifically transcultural situations.

The house is a symbol strongly invested by the children we receive in transcultural devices. Its structure echoes both the psychological and physical structure of the child but also that of family ties. The clinical situation of a family from Tunisia makes it possible to describe the system of the Métissages group and the symbol of the \"mother house\", both through drawings and games.

In the transcultural approach, emphasis is placed on cultural countertransference in order to account for caregivers\' implicit and explicit reactions with regard to patients and their history. As language is a constitutive element of culture, linguistic countertransference must be granted a place, in care, research and teaching.

The nursing interview, a key time point in patient care, is inhabited by mental representation, such as representation of the body, of the nurse and the patient. Whenever migratory dynamics are entangled in care dimensions, cultural counter-transfer has important repercussion in patient welcome. Training in transcultural clinic allows carers to have tools to counterbalance their cultural counter-transfer. A co-building of care process then becomes possible.

The native language is a vehicle for transmission and inscription into a culture. In children of migrants who grow up between two languages and two cultures, language develops in a context of bilingualism. This specific context requires bilingual assessments to ensure that a child\'s complete skills are assessed. The language assessment of non-French-speaking children and first-time immigrants, has been set up at Avicenne hospital in Bobigny. It is the first transcultural tool for the assessment of native languages.

The children of migrants are said to be \'bilingual\' as they grow up in a cultural and linguistic plurality. However, bilingualism is a complex notion which encompasses multiple definitions and very diverse bilingual family configurations. It is therefore difficult to establish developmental norms of balanced bilingualism. The notion of a language pathway seems to take into account more the creative process leading to the plurality of the bilingual configurations. Indeed, the bilingualism of the children of migrants is always a unique process in constant movement, the result of the unpredictability of the \"metissage\" of their cultural affiliations.

The question of mother tongues in the socio-educational context of school was the subject of a memorandum of 2016. Moreover, research in psychology and linguistics shows the extent to which the family language and culture are important elements in the construction of the child. These must be taken into account at school as well as in any support and care environment.

Supporting unaccompanied foreign minors requires a different clinical approach. These youngsters must be given individualised support to help them make the transition from exile and loss, to an existence as an individual, yet still a son or daughter. The drawing, as a transcultural and atemporal imprint, constitutes a tool enabling these young people to bring to the surface their unconscious thought processes, to exist and to come into being with dignity.
