Octenidine-based hydrogel shows anti-inflammatory and protease-inhibitory capacities in wounded human skin.

Octenidine dihydrochloride (OCT) is a widely used antiseptic molecule, promoting skin wound healing accompanied with improved scar quality after surgical procedures. However, the mechanisms by which OCT is contributing to tissue regeneration are not yet completely clear. In this study, we have used a superficial wound model by tape stripping of ex vivo human skin.

Re-epithelialization and immune cell behaviour in an ex vivo human skin model.

A large body of literature is available on wound healing in humans. Nonetheless, a standardized ex vivo wound model without disruption of the dermal compartment has not been put forward with compelling justification. Here, we present a novel wound model based on application of negative pressure and its effects for epidermal regeneration and immune cell behaviour.

The Antiseptic Octenidine Inhibits Langerhans Cell Activation and Modulates Cytokine Expression upon Superficial Wounding with Tape Stripping.

Ideal agents for the topical treatment of skin wounds should have antimicrobial efficacy without negative influence on wound healing. Octenidine (OCT) has become a widely used antiseptic in professional wound care, but its influence on several components of the wound healing process remains unclear. In the present study, we have used a superficial wound model using tape stripping on human full-thickness skin ex vivo to investigate the influence of OCT on epidermal Langerhans cells (LCs) and cytokine secretion pattern of skin cells during wound healing in a model without disruption of the normal skin structure.

A Preclinical Model for Studying Herpes Simplex Virus Infection.

Herpes simplex virus (HSV) infections can cause considerable morbidity. Currently, nucleoside analogues such as acyclovir are widely used for treatment. However, HSV infections resistant to these drugs are a clinical problem among immunocompromised patients.

An intra-individual surgical wound comparison shows that octenidine-based hydrogel wound dressing ameliorates scar appearance following abdominoplasty.

Hypertrophic scar formation because of surgical procedures is associated with higher levels of pain, a lower quality of life, and poor cosmetic outcome and requires more resources in follow-up management. An octenidine-based hydrogel has been shown to modulate immunological function in an in vitro wound model, suggesting an improved scar formation. In this prospective, randomised, observer-blinded, and intra-patient-controlled study, 45 patients who underwent abdominoplasty or mastectomy with transverse rectus abdominis muscle (TRAM) flap reconstruction were given both a standard postoperative wound dressing on one wound side and an octenidine-based hydrogel with transparent film dressing, covered with standard postoperative dressing on the other side.

Aseptic surgical preparation for upper eyelid blepharoplasty via full-face octenidine antiseptic without antibiotic medication shows effective prophylaxis against post-surgical wound infection.

Blepharoplasty is the third most common plastic surgical procedure in the USA. Due to the emergence of multiresistant bacteria, optimising the antiseptic procedure is crucial. Choice of antiseptics plays an important role as they may cause skin irritation and colouring of disinfected areas.

The posterior thigh flap for defect coverage of ischial pressure sores - a critical single-centre analysis.

The development of pressure sores is still not only an enormous economical but also a medical burden. Especially in the ischial region, the local defect coverage remains demanding as it is the main weight-bearing area in wheelchair-mobilised patients and is prone to high mobility. The purpose of our study was to report our long-time experience with the reconstruction of ischial pressure ulcers with the medially based posterior thigh flap.

The versatility of the medial thigh lift for defect coverage in the genito-perineal region.

Soft tissue defects in the genito-perineal region are predominantly because of trauma, infections, neoplasms or iatrogenic causes. As a result of the region's urological, reproductive and gastrointestinal function, defects in this area may cause devastating physical and psychological consequences as well as diminished sexual functioning. The purpose of this study was to examine the efficacy of implementing a medial thigh lift for defect coverage in the perineal region.

Viability of Lucilia sericata maggots after exposure to wound antiseptics.

After debridement and before dressing a wound with maggots of calliphorid flies, one frequently performed step is the application of antiseptics to the prepared wound bed. However, the concomitant application of antiseptic agents during maggot therapy is regarded controversial as antiseptics may interfere with maggots' viability. In this experimental in vitro study, the viability of fly maggots was investigated after exposure to various antiseptics frequently used in wound care.

Long-term quality-of-life improvement in gastric banding patients from body-contouring surgery.

Following my prior study of long-term results after laparoscopic gastric banding concerning operative outcome and complications involving the gastric band itself, I now focus on long-term quality-of-life improvement in the same study group after body-contouring surgery. As determined from our electronic patient data system, 72 patients from the former study group subsequently sought body-contouring surgery at our hospital after successful weight loss. Patients were enrolled in a telephone interview and asked about their expectations and body image before and after postbariatric aesthetic surgery and how it altered their well-being in addition to the weight loss achieved with the gastric band.

Hand hygiene--evaluation of three disinfectant hand sanitizers in a community setting.

Hand hygiene is acknowledged as the single most important measure to prevent nosocomial infections in the healthcare setting. Similarly, in non-clinical settings, hand hygiene is recognised as a key element in helping prevent the spread of infectious diseases. The aim of this study was to evaluate the efficacy of three different disinfectant hand sanitizers in reducing the burden of bacterial hand contamination in 60 healthy volunteers in a community setting, both before and after education about the correct use of hand sanitizers.

Occult moyamoya disease causing fulminant infarction after septorhinoplasty.

Moyamoya disease is an extremely rare cerebrovascular condition that predisposes affected patients to stroke in association with progressive stenosis of the intracranial internal carotid arteries and their proximal branches. To our knowledge, this is the first report of a lethal complication due to moyamoya disease after septorhinoplasty. A 25-year-old female Caucasian patient presented to our outpatient clinic with impaired nasal breathing for septorhinoplasty.

Comparison of short- and long-term results of drug-eluting vs. bare metal stenting in the porcine internal carotid artery.

Purpose: To evaluate the development of neointimal hyperplasia after implantation of drug-eluting stents (paclitaxel) compared to bare metal stents in porcine internal carotid arteries (ICAs).

Methods: While drug-eluting stents have effectively reduced neointimal proliferation in porcine external carotid arteries, the porcine internal carotid artery (ICA) is more sensitive to shear stress and altered flow conditions. Thus, a study was conducted to evaluate bare vs.

Implantation of paclitaxel-eluting stent impairs the vascular compliance of arteries in porcine coronary stenting model.

Background: The impaired compliance of large and medium-sized muscular arteries has been shown to correlate with the risk of adverse cardiovascular events. We assessed coronary artery distensibility using simultaneous intracoronary ultrasound and pressure wire measurements in porcine coronary arteries after implantation of paclitaxel-eluting (PES) and bare metal stents (BMS) and compared this with the histopathology of the arterial wall injury.

Methods: PES and BMS were implanted into porcine left coronary arteries under general anesthesia.
