Cosmetic outcome of skin adhesives versus transcutaneous sutures in laparoscopic port-site wounds: a prospective randomized controlled trial.

Background: In an elective laparoscopic surgery, the cosmetic outcome becomes increasingly important. We conducted a study to evaluate the cosmetic outcome 3 months after a laparoscopic procedure and compared skin adhesive (SA) versus transcutaneous suture (TS).

Methods: A randomized, controlled, prospective study was conducted at a single study centre in Hamburg, Germany.

Plasmons due to the interplay of Dirac and Schrödinger fermions.

We study the interplay between Dirac and Schrödinger fermions in the polarization properties of a two-dimensional electron gas (2DEG). Specifically, we analyze the low-energy sector of narrow-gap semiconductors described by a two-band Kane model. In the context of quantum spin Hall insulators, particularly, in Hg(Cd)Te quantum wells, this model is named the Bernevig-Hughes-Zhang model.

Deoxycholic acid causes DNA damage while inducing apoptotic resistance through NF-κB activation in benign Barrett's epithelial cells.

Gastroesophageal reflux is associated with adenocarcinoma in Barrett's esophagus, but the incidence of this tumor is rising, despite widespread use of acid-suppressing medications. This suggests that refluxed material other than acid might contribute to carcinogenesis. We looked for potentially carcinogenetic effects of two bile acids, deoxycholic acid (DCA) and ursodeoxycholic acid (UDCA), on Barrett's epithelial cells in vitro and in vivo.

A randomized, controlled study comparing the cosmetic outcome of a new wound closure device with Prolene suture closing caesarean wounds.

A prospective, randomised study was conducted to compare the wound closure performance and cosmetic outcome of caesarean section wounds closed with traditional Prolene suture or a new wound closure device (Leukosan(®) SkinLink). Sixty-one patients referred to primary section were allocated to wound closure with either Leukosan(®) SkinLink or Prolene suture. Cosmetic outcome as the primary measure was evaluated by the patient, the surgeon as well as by independent examiners blinded to the method of wound closure.
