RESUMEN
Objective: The robust safety and efficacy profile associated with the use of biodegradable fillers such as poly-L-lactic acid (PLLA) for facial rejuvenation has resulted in a growing interest in off-label use for various aesthetic applications, including gluteal augmentation. The authors describe a novel targeted and individualized technique of PLLA injection into the buttock region. Methods: The technique involves clinical and anatomical evaluations of the gluteal region, and there are three distinct approaches for injecting PLLA in the gluteal region based on the most important factor to be improved: (1) skin quality, (2) contour and lifting, or (3) projection and volume. Results: This novel technique is associated with favorable patient outcomes in terms of improvements across all key areas of gluteal augmentation; improvement in skin quality and laxity, contour improvement and lifting, and gluteal volume and projection. Since its initiation, this technique has been found to be both cost-effective and clinically efficacious, with demonstratable benefits achieved with a lower volume of PLLA compared to other PLLA injection techniques. Limitations: Assessment of patient outcomes with this technique have, to date, been subjective clinical observations, which does not include quantitative outcomes such as patient satisfaction data or safety outcomes. Conclusion: We describe an optimized and individualized approach for injecting the collagen biostimulator PLLA in the gluteal region according to the needs of each patient.
RESUMEN
The aim was to evaluate the effect of residual feed intake (RFI) on the histological, physical and mechanical characteristics of the sheep skin confined in full sun or shade. Dorper sheep (n = 64), male, with an initial bodyweight of 17.8 ± 2.43 kg was confined for 40 days to determine the RFI. After classification, 30 animals with positive RFI and 30 animals with negative RFI were selected, which were distributed in 2 confinement environments. This was a factorial arrangement of 2 (groups of animals-positive RFI and negative RFI) × 2 (environments-full sun and shade), with 15 animals for each combination of factors. The sheep remained in confinement for 60 days. After slaughter, skins were divided in half, and fragments were collected from the right portion for histological sections. The left part of each skin was subjected to tanning. Interaction effect RFI × environment was found in the evaluation of leather fragments in the horizontal direction on elongation at break, leather thickness and tear strength (p < 0.05). An isolated effect of the environment was found on elongation at break of leather fragments in the evaluation on the vertical direction (p = 0.01) and on the number of secondary follicles during the histological evaluation of the dorsal and lateral regions of the skin (p < 0.05). An effect of the interaction RFI × environment was observed for the thermostatic layer of the hip region (p = 0.03). Sheep with positive RFI and kept in confinement in full sun have a leather with greater elongation at break and tear strength, important aspects in determining the quality of the product by the leather industry.

A transgender individual is someone who does not identify with his or her biological sex1. During the transgender transition process, minimally invasive procedures (MIP) provide a versatile tool in the clinician's therapeutic armamentarium, since the changes can be impactful for the patient, yet reversible, especially for the patient who is unsure about proceeding with a definite surgery. We report 5 cases of facial feminization of transgender women, illustrating the use of minimally invasive facial remodeling procedures for male-to-female transitioning patients.
