Autologous Platelet-Rich Plasma Reduces Healing Time of Chronic Venous Leg Ulcers: A Prospective Observational Study.

The study investigated whether the application of dressings with autologous platelet-rich plasma (PRP) would reduce the healing time in patients with chronic venous leg ulcers. This is a prospective observational study that included 100 patients diagnosed with lower extremity venous insufficiency complicated by ulceration of a leg or foot, who had been after angioplasty of stenotic artery. Patients were divided into two groups of 50 each: treated with PRP (study group) and treated with conventional hydrocolloid dressings (control group).

Integration of Sonoelastography Into the TIRADS Lexicon Could Influence the Classification.

Aim: To determine the role of human growth factor in the healing of ulcers due to ischaemic diabetic foot syndrome (DFS) following previous angioplasty of the blood vessels of the lower leg and foot.

Material And Methods: The study group included 50 patients with ischaemic diabetic foot complicated by lower leg ulcers in which angioplasty of the stenotic arteries in the distal lower leg and foot was performed.

Diagnostic Performance of Shear Wave Elastography Parameters Alone and in Combination with Conventional B-Mode Ultrasound Parameters for the Characterization of Thyroid Nodules: A Prospective, Dual-Center Study.

The aims of our study were to determine whether shear wave elastography (SWE) can improve the conventional B-mode differentiation of thyroid lesions, determine the most accurate SWE parameter for differentiation and assess the influence of microcalcifications and chronic autoimmune thyroiditis on SWE values. We examined 119 patients with 169 thyroid nodules who prospectively underwent B-mode ultrasound and SWE using the same ultrasound machine. The parameters assessed using SWE were: mean elasticity within the entire lesion (SWE-whole) and mean (SWE-mean) and maximum (SWE-max) elasticity for a 2-mm-diameter region of interest in the stiffest portion of the lesion, excluding microcalcifications.

The Effect of Local Platelet Rich Plasma Therapy on the Composition of Bacterial Flora in Chronic Venous Leg Ulcer.

Microbial colonisation of chronic venous ulcers and synergism between bacterial species slow down the healing process. The study aimed at performing qualitative analysis of microbial flora in venous leg ulcers treated with platelet rich plasma (PRP). Twenty two women and twelve men aged 47-90 years were treated with PRP at our department between 2012 and 2015.

A study of the activity and effectiveness of recombinant fibroblast growth factor (Q40P/S47I/H93G rFGF-1) in anti-aging treatment.

Introduction: Fibroblast growth factor 1 (FGF-1) is a powerful mitogen involved in the stimulation of DNA synthesis and the proliferation of a wide variety of cell types. Fibroblast growth factor 1 was genetically modified to improve its thermal stability and resistance to protease degradation without losing its biological activity.

Aim: To study the impact of Q40P/S47I/H93G rFGF-1 on skin cells, its penetration through the skin and the evaluation of the rFGF-1-cosmetic product properties.

Shear wave elastography in medullary thyroid carcinoma diagnostics.

Unlabelled: Shear wave elastography (SWE) is a modern method for the assessment of tissue stiffness. There has been a growing interest in the use of this technique for characterizing thyroid focal lesions, including preoperative diagnostics.

Aim: The aim of the study was to assess the clinical usefulness of SWE in medullary thyroid carcinoma (MTC) diagnostics.

Skin imaging with high frequency ultrasound - preliminary results.

This study presents the detailed construction and the principle of performance of high frequency (HF) ultrasound scanner for skin examination. The aim of this study was to show a difference between diseased and healthy skin and to evaluate the usefulness of the scanner in monitoring of therapeutic efficacy of morphea and lichen sclerosus et atrophicus (LSA). We examined 48 patients aged between 15 and 64 years; 25 patients with plaque-type morphea, nine patients with linear morphea and 14 patients with LSA.

[False aneurysms of lower extremity arteries: noninvasive preop diagnosis with magnetic resonance angiography and Doppler ultrasonography].

The purpose of this study was to work out a diagnostic algorithm to be used in patients surgically treated because of a false aneurysm of arteries supplying the lower limb. The study includes preoperative vessel evaluation as well as treatment results assessment with MRA and US methods. Examinations included until now 16 patients with clinical false aneurysm suspicion.

[Examination of veins with magnetic resonance imaging and it's place in the diagnostic algorithm of patients with deep venous thrombophlebitis].

In a group of 1246 patients treated in the Department of Maxillofacial Surgery-Institute of Stomatology, Medical Academy in Warsaw, in a period of 3 years (1984-1986) late results of treatment of mandibular fractures were assessed. In the assessment the range of mandible abduction, function of temporomandibular joints, occlusal abnormalities, the sensory function in the area innervated by the mental nerves and the condition of posttraumatic scars changing the morphology and aesthetic appearance of the face were considered. Limitation of mandibular abduction after treatment was found in 39 cases.
