La peau vue par différentes méthodes d’imagerie cutanée non invasive [Cutaneous visualization by different non-invasive skin imaging methods]

The development of in vivo skin imaging technologies has been booming for several decades. Their advantages are indisputable, especially as they are non-invasive. Their place is already well established in onco-dermatology and it is just a question of time for them to be used with success in other fields of dermatology, including pediatric dermatology. In this paper we will discuss 3 of these skin imaging techniques used in dermatology at the CHUV, including Optical Coherence Tomography (OCT), Reflectance Confocal Microscopy (RCM) and the most recent: Line-field Confocal Optical Coherence Tomography (LC-OCT)

In vivo evaluation of skin of children with LC-OCT: An objective assessment.

Several non-invasive skin imaging methods have been developed in recent years. Line-field confocal optical coherence tomography (LC-OCT) is one of them, leading to the best compromise in terms of resolution and penetration depth. Skin biopsies are an essential technique in paediatric dermatology, but they are a major stressful event for the child and their parents. Current LC-OCT studies have not been dedicated to a paediatric population. If, however, LC-OCT proves to be helpful in children, it may help guide and decrease a certain number of skin biopsies. (1) To evaluate the feasibility of using LC-OCT in paediatric patients, and (2) to assess the maturation of skin structures in children over time with this method. In vivo LC-OCT images were collected on six specific body regions (forehead, forearm, chest, back, dorsum of the hand and palmar surface) and in six age groups (between the ages of 0 and 16 years). In all body areas and age groups assessed, 9 of 10 images were rated as good-to-excellent, the only exception were the images acquired on the palmar surface. LC-OCT allowed visualizing very well the skin structures up to a penetration of 500 μm. We observed that the body regions located on the upper extremities of the body (forearm, dorsum of the hand and palmar surface) showed both a maturation on their structure and differences in thickness with respect to the other regions evaluated. LC-OCT can easily be used for non-invasive imaging of children's skin and allows to document progressive skin changes in the different age groups. It may be a useful asset for imaging and diagnosing superficial skin disorders and as such reducing the number of invasive procedures while increasing the speed of diagnosis in the paediatric population

Télémédecine en dermatologie pédiatrique : mise au point sur les pratiques actuelles [Telemedicine in pediatric dermatology:focus on current practices]

Pediatric teledermatology (PTD) allows offering long distance health care advice in pediatric dermatology trough telecommunication technologies. Due to the lack of pediatric dermatologists, the frequency of dermatological questions in general pediatrics, the visual nature of the specialty, and the rare occurrence of vital emergencies in dermatology, PTD appears to be a good option for giving long distance advice in a certain number of skin conditions. In this article, we will discuss benefits and limitations of PTD. We will also talk about diagnostic and therapeutic concordance between PTD and traditional consultations, as well as the most frequent advices asked
