Biomarker-guided acute kidney injury risk assessment under liberal versus restrictive fluid therapy - the prospective-randomized MAYDAY-trial.

Acute kidney injury (AKI) prevalence in surgical patients is high, emphasizing the need for preventative measures. This study addresses the insufficient evidence on nephroprotective intraoperative fluid resuscitation and highlights the drawbacks of relying solely on serum creatinine/urine output to monitor kidney function. This study assessed the impact of intraoperative fluid management on AKI in female breast cancer patients undergoing autologous breast reconstruction, utilizing novel urinary biomarkers (TIMP-2 and IGFBP-7).

Adipose Tissue-Derived Stem Cell Yield Depends on Isolation Protocol and Cell Counting Method.

In plastic surgery, lipofilling is a frequent procedure. Unsatisfactory vascularization and impaired cell vitality can lead to unpredictable take rates in the fat graft. The proliferation and neovascularization inducing properties of adipose tissue-derived stem cells may contribute to solve this problem.

New aspects in digital breast assessment: further refinement of a method for automated digital anthropometry.

Purpose: In this trial, we used a previously developed prototype software to assess aesthetic results after reconstructive surgery for congenital breast asymmetry using automated anthropometry. To prove the consensus between the manual and automatic digital measurements, we evaluated the software by comparing the manual and automatic measurements of 46 breasts.

Methods: Twenty-three patients who underwent reconstructive surgery for congenital breast asymmetry at our institution were examined and underwent 3D surface imaging.

"Topographic Shift": a new digital approach to evaluating topographic changes of the female breast.

Purpose: To assess precise topographic changes of the breast, objective documentation and evaluation of pre- and postoperative results are crucial. New technologies for mapping the body using digital, three-dimensional surface measurements have offered novel ways to numerically assess the female breast. Due to the lack of clear demarcation points of the breast contour, the selection of landmarks on the breast is highly dependent on the examiner, and, therefore, is prone to error when conducting before-after comparisons of the same breast.

[Abdominoplasty without closed-suction drains: a randomised controlled trial].

Introduction:  There is insufficient scientific evidence from randomised controlled trials to support the routine use of closed-suction drains in body contouring procedures. The aim of this study was to evaluate cumulative seroma volume, length of hospital stay and complication rates in abdominoplasty patients without drains in direct comparison with a cohort receiving drains.

Material And Methods:  Abdominoplasty patients were prospectively randomised in two study groups with (MD) and without (OD) placement of closed-suction drains.

Clinical Impact of DIEP Flap Perforator Characteristics - A Prospective Indocyanine Green Fluorescence Imaging Study.

Background: The question to what extent perfusion in deep inferior epigastric perforator (DIEP) flaps depends on specific perforator characteristics has been raised. Anatomical studies and previous clinical trials focussing on DIEP flap perfusion resulted in discrepancies. This prospective study investigates how perforator row, number and diameter affect DIEP flap microperfusion via Indocyanine Green (ICG) fluorescence angiography.

Development of a Patient-Based Goniometric System for the Assessment of Contracture Conditions in Dupuytren's Disease.

Background: Treatment outcomes of Dupuytren's disease depend largely on degree of contracture and biological severity. Longitudinal assessment of each is crucial for effective care and long-term outcome assessment. Ideally, each Dupuytren's patient should have ongoing interval evaluations.

[Preferred treatment options of German hand surgeons in Dupuytren disease].

Aim: This study was performed to determine whether between 2015 and 2017 there has been a change in the preferred method of treatment of Dupuytren disease by German hand surgeons, especially with respect to percutaneous needle fasciotomy.

Method: In 2015 and 2017, 530 members of the German Society for Surgery of the Hand were invited to take part in an online survey, asking for their preferred treatment for Dupuytren disease, including decision criteria and in relation to Tubiana stages. 110 and 101 responders, respectively, took part.
