Optimizing Safety and Precision for Secondary Liposuctions: Integrating Intraoperative Ultrasound With VASER Technology.

Background: Liposuction has gained significant popularity, leading to increased demand for secondary procedures due to complications such as scars and fibrosis that affect aesthetic outcomes. High-Definition Liposuction (HDL) has emerged as a preferred technique, but the presence of fibrosis from prior surgeries may limit its effectiveness.

Objectives: This study explores the application of ultrasound-assisted VASER (Vibration Amplification of Sound Energy at Resonance; VASER-Solta Medical, Bothell, WA) liposuction in secondary abdominal liposculpture to address these challenges.

Case report: Immediate thumb reconstruction using reverse radial flap surgical technique.

Introduction: The human hand is highly mobile and functional, being essential in the prehensile function. Thumb injuries are divided into distal, medial and proximal. Post-traumatic defects in the thumb can lead significant functional impairment.

Favorable Radiographic Response in a Patient With an Oligodendroglioma Treated With Azacitidine and Venetoclax for Acute Myeloid Leukemia.

The standard chemotherapy for treating oligodendrogliomas consists of a combination of procarbazine, lomustine, and vincristine (PCV). The combination of hypomethylating agents like azacitidine and BCL2 inhibitors like venetoclax has not been formally studied in the treatment of glial tumors. The combination of these two drugs is commonly used to treat acute myeloid leukemia (AML), with IDH-mutant disease being a particularly sensitive subtype.

Fibrosis Management Algorithm in Secondary Liposculpture.

Background: Liposuction is considered one of the most common procedures in plastic surgery. However, major postoperative complications such as visceral injury, fluid overload, and necrotizing fasciitis still occur. Likewise, minor complications such as ecchymosis, seromas, infections, and contour irregularities that do not threaten the life of the patient do generate significant dissatisfaction.

92 Mb/s Fat-Intrabody Communication (Fat-IBC) With Low-Cost WLAN Hardware.

The human subcutaneous fat layer, skin and muscle together act as a waveguide for microwave transmissions and provide a low-loss communication medium for implantable and wearable body area networks (BAN). In this work, fat-intrabody communication (Fat-IBC) as a human body-centric wireless communication link is explored. To reach a target 64 Mb/s inbody communication, wireless LAN in the 2.

Adipose Tissue Transfer in Dynamic Definition Liposculpture-PART I. Back: Latissimus Dorsi and Trapezius Muscles.

Unlabelled: The aesthetics for the male posterior torso remain a topic not fully studied in body contouring surgery, neither the lipoinjection of its muscles have been considered before. As a result, we carried out a retrospective cohort study including patients who underwent fat grafting of either the trapezius or the latissimus dorsi muscles as part of dynamic definition liposculpture (HD2).

Methods: We performed cadaveric dissections to support the fat grafting technique for both the trapezius and the latissimus dorsi muscles.

Adipose Tissue Transfer in Dynamic Definition Liposculpture Part II. The Lower Limb: Gastrocnemius, Vastus Medialis, Vastus Lateralis, and Rectus Femoris Muscles.

Unlabelled: One big challenge of body contouring surgery is the liposculpture of the lower limbs, probably because of the imperative symmetry and the risk of contour irregularities. We are reporting our experience in fat grafting of the thighs and calves for men and women undergoing dynamic definition liposculpture.

Methods: We did cadaveric dissections of the vastus lateralis, vastus medialis, rectus femoris, and gastrocnemius muscles and identified each of their primary pedicles.

Adipose Tissue Transfer in Dynamic Definition Liposculpture PART III. The Arms: Biceps, Triceps, and Deltoids.

Unlabelled: Arm contouring usually represents a challenge for the surgeon due to zones with high risk of irregularities/asymmetries, the variable degree of skin laxity, and the differences between patient/gender preferences. In men, the bigger and muscular the arms the better, while women tend to prefer a slim and soft silhouette.

Methods: We performed arm cadaveric dissections and also searched our records for patients who underwent fat grafting of the arm in addition to HD2, from January 2016 to May 2022 at a single center in Bogotá, Colombia.

High-Definition Liposculpture 18-Year Evolution: Patient Safety and Aesthetic Outcomes.

Background: High-definition liposculpture (HDL) emerged as an innovative surgical technique that allowed plastic surgeons to achieve improved aesthetic results with a natural and athletic appearance using minimal incisions and with imperceptible scarring. Its targets are high aesthetic standards and patient safety.

Purpose: This article summarizes the evolution of HDL by explaining upgrades to the original technique and comparing the complication rates among them.

Predictors for limb amputation in war vascular trauma: A 20-years retrospective analysis from the Colombian armed conflict.

Background: The Latin American military vascular trauma is virtually unknown. The aim of this study was to describe severe war vascular trauma during the last 20 years of the Colombian armed conflict, and to identify predictors of limb amputation.

Methods: Retrospective analysis of a follow-up cohort from 1999 to 2019 of patients with associated severe vascular injuries (ISS >15) in the Colombian armed conflict treated at the Hospital Militar Central.

H-Wing Neoumbilicoplasty: A New Technique for Advanced Abdominoplasty and Umbilical Zones by Gender.

Background: Multiple umbilicoplasty techniques have been described, even more after the advent of full tummy tuck procedures and the neoumbilicoplasty (X-shaped incision) described by the authors in a previous report. The authors decided to upgrade the technique (H-wing incision) because the former procedure is associated with relatively common complications. The authors report a case series of an upgraded technique for neoumbilicoplasty (H-wing technique), comparing its outcomes with their previous standard procedure (X-shaped incision).

Decision-Making Algorithm for Advanced Excisional Body Contouring: Dynamic Definition Solutions for Skin Laxity.

Background: Excisional body contour surgery is the cornerstone treatment for skin laxity. Decision-making can be challenging when selecting the procedure. Dynamic definition liposculpture allows the surgeon to carve the underlying anatomy and provide more natural results, in which umbilical shape and position play a crucial role.

Use of Tranexamic Acid in Liposculpture: A Double-Blind, Multicenter, Randomized Clinical Trial.

Background: Intraoperative hemostasis should be performed with great caution because bleeding is a huge enemy of patient safety during surgery. Tranexamic acid is a lysine synthetic derivate that inhibits fibrinolysis and diminishes the bleeding by blocking the five lysine-binding sites for plasminogen. The authors compare the efficacy of tranexamic acid versus placebo as a hemostatic agent in liposculpture procedures.

The authors present their experience with high-definition lipoabdominoplasty with transverse plication in men.

Toward environmentally friendly direct reduced iron production: A novel route of comprehensive utilization of blast furnace dust and electric arc furnace dust.

In this study, a novel method for producing direct reduced iron (DRI) powders based on microwave-assisted self-reduction of core-shell composite pellets composed of blast furnace (BF) dust and hazardous electric arc furnace (EAF) dust followed by magnetic separation was reported. The proper core-shell structure of the composite pellets was designed according to the rule of impedance matching and properties of BF dust and EAF dust by adjusting the thickness of shell (i.e.

Deep Learning of Nanopore Sensing Signals Using a Bi-Path Network.

Temporal changes in electrical resistance of a nanopore sensor caused by translocating target analytes are recorded as a sequence of pulses on current traces. Prevalent algorithms for feature extraction in pulse-like signals lack objectivity because empirical amplitude thresholds are user-defined to single out the pulses from the noisy background. Here, we use deep learning for feature extraction based on a bi-path network (B-Net).

MAS: Standalone Microwave Resonator to Assess Muscle Quality.

Microwave-based sensing for tissue analysis is recently gaining interest due to advantages such as non-ionizing radiation and non-invasiveness. We have developed a set of transmission sensors for microwave-based real-time sensing to quantify muscle mass and quality. In connection, we verified the sensors by 3D simulations, tested them in a laboratory on a homogeneous three-layer tissue model, and collected pilot clinical data in 20 patients and 25 healthy volunteers.
