Surgical practices of cosmetic breast augmentation by implants among 411 French plastic surgeons.

Introduction: Breast augmentation is one of the most frequently performed cosmetic surgeries in the world. However, there is no standardized surgical procedure for performing breast augmentation. Many modalities exist for this surgery which may explain why practices vary greatly from one surgeon to another.

Latent space of a small genetic network: Geometry of dynamics and information.

The high-dimensional character of most biological systems presents genuine challenges for modeling and prediction. Here we propose a neural network-based approach for dimensionality reduction and analysis of biological gene expression data, using, as a case study, a well-known genetic network in the early embryo, the gap gene patterning system. We build an autoencoder compressing the dynamics of spatial gap gene expression into a two-dimensional (2D) latent map.

[Dorsal skin defect: What solutions exist?].

Dorsal subcutaneous or cutaneous defects can be of multiple origin: tumor, congenital malformation, trauma, chronic radiodermitis ulceration, parting of sutures or spine surgery infection, pressure sore, etc. Wound healing of these defects can be really difficult to obtain with simple processes, such as direct sutures or skingrafts, and often implies skin flap surgery. The rarity of recipients vessels from the dorsal area makes free flaps surgery harduous.

Coverage losses of substance in the shoulder.

Losses of substance of the shoulder are less common than elsewhere in the upper limb. They arise essentially from tumors (sarcomas), infectious diseases (hidradenitis) or traumatic events, (burns). The objectives of reconstruction depend on whether the losses of substance are located on the curve of the shoulder or in the axillary area.
