Use of submental and submandibular free vascularized lymph node transfer for treatment of scrotal lymphedema: Report of two cases.

Genital lymphedema is a rare condition in males that can lead to difficulty in voiding, sexual function, hygiene, and mobility. Only several methods of treatment have been developed and studied, primarily focusing on restoring patency of diseased lymph channels or resection of affected tissue. We are the first to describe the surgical technique and our experience of using free submental and submandibular arterio-venous vascularized lymph node transfer specifically for the treatment of scrotal edema.

Patent Blue dye allergy and the deep inferior epigastric perforator free flap: a unique interaction.

Patent Blue dye for sentinel lymph node biopsy is associated with systemic allergic response and generalized blue hue. We report a unique case of successful free flap transfer in this setting. Despite inotropic support and abnormal blue hue, allergic response does not preclude safe flap transfer and monitoring.

Enhanced liver progenitor cell survival and differentiation in vivo by spheroid implantation in a vascularized tissue engineering chamber.

Liver tissue engineering is hampered by poor implanted cell survival due to inadequate vascularization and cell-cell/cell-matrix interactions. Here, we use liver progenitor cell (LPC) spheroids to enhance cell-cell/cell-matrix interactions, with implantation into an angiogenic in vivo mouse chamber. Spheroids were generated in vitro in methylcellulose medium.

Comparing sterile bag rubbing and paint on technique in skin preparation of the hands.

Background: The aim of this study was to compare two techniques for surgical site skin preparation in hand surgery.

Methods: We compared the standard sponge paint technique versus a plastic bag immersion technique using a 10% povidone-iodine with alcohol solution (Betadine, ORION Laboratories Pty Ltd, Balcatta,WA,Australia) to prepare surgical site skin for hand surgery. This sterile bag rubbing technique involves using a sterile plastic bag filled with 60 mL of Betadine solution to immerse the subjects' hand.
