AI Article Synopsis
- Skin serves as a complex material that covers the human body, and understanding its mechanical properties is crucial for applications like cosmetic surgery and treating skin diseases.
- The study aimed to identify and calibrate a material constitutive model for skin while establishing universal properties that are consistent across different patients.
- Uniaxial tests on breast skin samples showed that the model parameters, particularly regarding their response to previous stretching, demonstrated consistent behavior regardless of individual specimen differences.
Article Abstract
Skin is a complex material covering the entire surface of the human body. Studying the mechanical properties of skin to calibrate a constitutive model is of great importance to many applications such as plastic or cosmetic surgery and treatment of skin-based diseases like decubitus ulcers. The main objective of the present study was to identify and calibrate an appropriate material constitutive model for skin and establish certain universal properties that are independent of patient-specific variability. We performed uniaxial tests performed on breast skin specimens freshly harvested during mastectomy. Two different constitutive models - one phenomenological and another microstructurally inspired - were used to interpret the mechanical responses observed in the experiments. Remarkably, we found that the model parameters that characterize dependence on previous maximum stretch (or preconditioning) exhibited specimen-independent universal behavior.

This article aims to identify the relationship between material deprivation and mortality from breast, cervical, and prostate neoplasms in the Brazilian adult population and the relationship between ethnicity/skin color and material deprivation. This cross-sectional ecological study calculated the mean mortality rate per 100,000 inhabitants, and deaths were standardized by age and gender and redistributed per to ill-defined causes, stratified by age group and ethnicity/skin color. We applied the Negative Binomial model, containing the interaction between ethnicity/skin color and the Brazilian Deprivation Index (IBP).

Background: Patients with symptomatic breast hypertrophy typically suffer from chronic back pain, recurrent skin irritation at the inframammary fold and/or low self-esteem resulting in impaired quality of life. Reduction mammaplasty has been shown to effectively treat symptomatic breast hypertrophy with high patient satisfaction. Despite the obvious benefits, reimbursement requests for reduction mammaplasty are initially often refused by the patient's health insurance company, thereby frequently resulting in additional examinations and eventually extra expenses.

Introduction: Breast surgeries are classified as clean procedures associated with a lower risk of post-operative infections; however, the reported infection rates post-breast surgeries are still significantly high. Surgical site infections (SSIs) are indeed one of the most common and serious complications following breast surgery.
Methodology: A retrospective study assessed the rate of SSIs post-breast reconstructive surgery after the implementation of the infection control protocol at James Cook University Hospital and Friarage Hospital from December 2022 to June 2024.

Recurrence beyond the second year of diagnosis and metastasis to the skin and eyelids are rare occurrences in breast cancer. When cutaneous metastases present without local recurrence, they pose a significant diagnostic challenge. Here, we describe a case of breast cancer that recurred 16 years after the initial treatment, with the only indication of recurrence being unusual skin and eyelid lesions.

Neurofibromatosis type 1 (NF1, formerly Recklinghausen's disease) is a genetic tumor predisposition syndrome in which the mutation of a tumor suppressor gene (neurofibromin) leads to the development of mostly benign neurofibromas of the skin and the central and peripheral nervous systems and malformations or tumors of other organ systems. Patients with NF1 should receive lifelong interdisciplinary care in specialized centers and important treatment decisions should be made by a regularly meeting interdisciplinary panel of experts. Plastic surgery plays an important role in the multidisciplinary management of all clinical forms of NF1-associated peripheral nerve sheath tumors, from cutaneous and subcutaneous to deep nodular and diffuse plexiform neurofibromas.
