Changes in gene expression in pressure ulcers debrided by different approaches - a pilot study.

Pressure ulcers (PUs), also known as pressure injuries, are chronic wounds that represent potential lifelong complications. Pressure ulcers of a deep category (III and IV) are often indicated for surgical treatment - debridement and surgical reconstruction. Sharp surgical debridement is widely used in the debridement of PUs; however, the Versajet® hydrosurgery system is becoming an increasingly popular tool for tangential excision in surgery due to its numerous advantages.

Chronic venous insufficiency and venous leg ulcers: Aetiology, on the pathophysiology-based treatment.

The chronic venous disease covers a wide spectrum of venous disorders that are characterized by severely impaired blood return that primarily affects veins in the lower extremities. Morphological and functional abnormalities of the venous system led to chronic venous insufficiency (CVI), and present as leg heaviness/achiness, edema, telangiectasia, and varices. The term 'chronic venous insufficiency' (CVI) refers to a disease of greater severity.

Reconstruction of the Tongue after Hemiglossectomy Using Serratus Anterior Muscle Free Flap.

Background: Serratus anterior muscle free flap is widely used in numerous indicated reconstructions. Only a few studies have dealt with the use of this flap in tongue reconstruction.

Materials And Methods: We present a case series of 7 patients with carcinoma of the tongue who underwent hemiglossectomy followed by immediate reconstruction with serratus anterior muscle free flap between January 2017 and December 2019 at the University Hospital Brno.

Signaling pathways in cutaneous wound healing.

Wound healing is a very complex process, where variety of different pathways is activated, depending on the phase of healing. Improper or interrupted healing might result in development of chronic wounds. Therefore, novel approaches based on detailed knowledge of signalling pathways that are activated during acute or chronic cutaneous wound healing enables quicker and more effective healing.

Fatty Acid Supplementation Affects Skin Wound Healing in a Rat Model.

Polyunsaturated fatty acids (PUFA) play an important role in reparative processes. The ratio of PUFAs n-3 to n-6 may affect wound healing. The study aimed to evaluate the effect of dietary supplementation with n-3 and n-6 PUFA in two proportions on skin wounds in laboratory rats.

Reverse blood flow as an option in mandibular reconstruction using a two-segment fibula free flap.

Microsurgical reconstruction is currently considered a method of choice for the repair of soft tissue or bony defects in head and neck surgery. This technical note presents the use of a reverse flow technique in mandibular reconstruction with two segments of fibula free flap in a patient with bilateral pseudoarthrosis. In the standard procedure, both segments of the fibula are supplied by one donor vascular pedicle with normal antegrade blood flow.

Machine Learning-Based Pressure Ulcer Prediction in Modular Critical Care Data.

Increasingly available open medical and health datasets encourage data-driven research with a promise of improving patient care through knowledge discovery and algorithm development. Among efficient approaches to such high-dimensional problems are a number of machine learning methods, which are applied in this paper to pressure ulcer prediction in modular critical care data. An inherent property of many health-related datasets is a high number of irregularly sampled time-variant and scarcely populated features, often exceeding the number of observations.

Reconstruction of Extensive Chest Wall Defects Using Light-Weight Condensed Polytetrafl uoroethylene Mesh - Case Reports.

Tumors of the chest wall require extensive surgical intervention, which includes radical resection of the tumor mass followed by reconstruction of the defect. The depth of the defects may vary from a shallow one to a deep defect with exposure of the internal organs. In reconstruction of the chest wall, it is important to ensure the stability of the chest.

RECONSTRUCTION OF DEEP HEAD BURN WITH A FREE FLAP - A CASE REPORT.

Third degree burn trauma of the head and neck requires an interdisciplinary approach. After emergency care and hemodynamic stabilization of the patient the focus lies on the reconstruction of the damaged tissue. The options of reconstruction are influenced by the general condition of the patient and by the condition of the surrounding tissues.

The importance of a multidisciplinary approach in the treatment of mutilating electrical injury: a case study.

Electrical burns are not ranked among the most frequent type of injuries, but they have the most devastating potential of all thermal injuries and often cause lifelong stigmatization. Those primarily affected are young males: work injuries predominate. An electrical burn is a specific nosological unit that has multiple acute and chronic abnormal manifestations.
