Two-year follow-up of patients undergoing transcatheter aortic valve implantation using a self-expanding valve prosthesis

The purpose of this study was to evaluate the safety, device performance, and clinical outcome up to 2 years for patients undergoing transcatheter aortic valve implantation (TAVI).

Prospective randomized trial comparing sutured with sutureless mesh fixation for Lichtenstein hernia repair: long-term results

Following Lichtenstein hernia repair, up to 25% of patients experience prolonged postoperative and chronic pain as well as discomfort in the groin. One of the underlying causes of these complaints are the compression or irritation of nerves by the sutures used to fixate the mesh. We compared the level and rate of chronic pain in patients operated with the classical Lichtenstein technique fixated by sutures to patients with sutureless mesh fixation technique.

Presentation, microsurgical therapy, and clinical outcomes in three cases of expanding melanonychia of the nail unit in children

The management of expanding melanonychia in childhood is controversial. Here, we present three cases and discuss their operating indications and reconstruction. Between January 1, 1995 and December 31, 2007, one boy and two girls, were operated for expanding melanonychia, involving the thumb, index finger or the middle finger. They were 2, 4, and 7 years at the time of surgery. A complete resection of the nail plate was performed followed by a direct finger reconstruction using a free short-pedicle vascularized nail flap of the toe. Histology showed a junctional nevus in all cases. The follow-ups were after 2, 3, and 5 years and without any complications or recurrence. Regarding reconstruction, the mean Foucher and Leclère score were, respectively, 17 and 16 points. It is concluded that for expanding melanonychia, in case of doubt, an examination of the entire lesion is necessary. Reconstruction of the nail unit after wide excision with nail plate ablation can be performed using microsurgery as discussed below. However, new guidelines on shave biopsy can make this microsurgical procedure obsolete.

ADAM: Administration and Deployment of Adhoc Mesh Networks

Costly on-site node repairs in wireless mesh networks (WMNs) can be required due to misconfiguration, corrupt software updates, or unavailability during updates. We propose ADAM as a novel management framework that guarantees accessibility of individual nodes in these situations. ADAM uses a decentralised distribution mechanism and self-healing mechanisms for safe configuration and software updates. In order to implement the ADAM management and self-healing mechanisms, an easy-to-learn and extendable build system for a small footprint embedded Linux distribution for WMNs has been developed. The paper presents the ADAM concept, the build system for the Linux distribution and the management architecture.

Treatment for long-segment femoro-popliteal obstructions: initial experience with a 4-F compatible self-expanding nitinol stent and review of the literature

The aim of this paper was to evaluate the efficacy of a novel 4-F compatible self-expanding Nitinol stent for the treatment of long femoro-popliteal obstructions.

Intraperitoneal mesh implantation for fascial dehiscence and open abdomen

Postoperative fascial dehiscence and open abdomen are severe postoperative complications and are associated with surgical site infections, fistula, and hernia formation at long-term follow-up. This study was designed to investigate whether intraperitoneal implantation of a composite prosthetic mesh is feasible and safe.
