The Relationship between Histological Composition and Metabolic Profile in Breast Tumors and Peritumoral Tissue Determined with H HR-MAS NMR Spectroscopy.

Breast tumors constitute the complex entities composed of cancer cells and stromal components. The compositional heterogeneity should be taken into account in bulk tissue metabolomics studies. The aim of this work was to find the relation between the histological content and H HR-MAS (high-resolution magic angle spinning nuclear magnetic resonance) metabolic profiles of the tissue samples excised from the breast tumors and the peritumoral areas in 39 patients diagnosed with invasive breast carcinoma.

Fibular Free Flap and Iliac Crest Free Flap Mandibular Reconstruction In Patients With Mandibular Ameloblastomas.

Ameloblastoma (AM) is the most common, locally aggressive odontogenic tumor. It comprises about 1% of all head and neck neoplasms. It occurs mainly in young adults in their 3rd and 4th decade of life.

Do surgeons use double gloves during surgery? Results of a survey.

<b>Introduction:</b> The perforation of gloves during surgical procedures is quite common. A cheap and quite effective method of reducing the risk of blood-borne infections is wearing two pairs of gloves. Unfortunately, some surgeons are reluctant to it, and they report decreased dexterity and sensation.

First Complex Allotransplantation of Neck Organs: Larynx, Trachea, Pharynx, Esophagus, Thyroid, Parathyroid Glands, and Anterior Cervical Wall: A Case Report.

Objective: Evaluate the possibility of performing a complex vascular allotransplant of all neck organs including skin.

Summary Background Data: There are 2 previous attempts described in the literature, none of them being that complex. The first one is nonfunctional due to chronic rejection, the second one is viable yet considerably limited in complexity (no parathyroids, no skin).

The use of a pedunculated, extended latissimus dorsi flap in primary and secondary breast reconstruction procedures--case report.

The extended latissimus dorsi flap (LD) is used in breast reconstruction since the 70's. LD flap is often used in corrective surgery in cases of unsatisfactory cosmetic results after breast-conserving therapy. In our department LD flap has several uses.

The use of three free flaps in the simultaneous reconstruction of the nose after extensive resection due to malignant cancer.

Reconstructive techniques for extended posttraumatic or post-resectional nose defects are well described. Small defects can usually be closed using local flaps with a good esthetic result. Extended resections in the mentioned area require more complex reconstruction methods, including microvascular techniques.

Salvage surgery of recurrence after laryngectomy--when should the alt free flap be modified?

Background: Reconstruction of the pharynx and cervical esophagus has significantly progressed in the last 2 decades. A revolution in microvascular surgery has provided numerous choices for primary restoration, or in secondary reconstructions necessary for recurrences or complications of primary surgery. The goals of reconstruction after laryngopharyngoesophagectomy are to provide continuity of the alimentary tract, to protect major blood vessels, to heal the primary wound, and to restore the swallowing and breathing functions with minimal donor site and neck morbidity and deformation.

The use of prefabrication technique in microvascular reconstructive surgery.

Aim Of The Study: The aim of the study was to develop standards for the prefabrication of free microvascular flaps in an animal model, followed by their application in clinical practice, and quantitative/qualitative microscopic assessment of the extent of development of a new microvascular network.

Material And Methods: The study was carried out in 10 experimental pigs. As the first stage, a total of 20 prefabricated flaps were created using polytetrafluoroethylene (PTFE) as a support material, placed horizontally over an isolated and distally closed vascular pedicle based on superficial abdominal vessels.
