The acquisition of a medical professorship represents a significant step in a physician's academic career. The responsibility as well as the honor and the associated obligations are significant; ...however, the requirements to become a medical professor vary in Germany.
We analyzed the variable requirements for prospective medical professors in Germany, with special focus on the tenure track concept and the U.S. system.
Based on an online research, we queried German medical faculty regulations to obtain a medical professorship within Germany.
We analyzed 35 German universities. On average, 11 publications are required after "venia legendi" to meet professorship (apl) prerequisites (median x̅ = 10, max = 24, min = 6, n = 16), whereas 6 publications with first or last authorship are required on average (x̅ = 6, max = 16, min = 4, n = 26). In most German universities, it takes an average of 4 years after gaining habilitation to apply for a professorship (x̅ = 5 years, max = 6 years, min = 2 years). Candidates for university chair positions, however, can shorten this period by an average of 38%.
In the German academic system, the prerequisites to gain a professorship differ among universities. Due to different scientific cooperation and exchange programs, research and academic activities have reached an intense international exchange level. Yet there is no international or even national standardization, quality assurance, and comparability to gain a medical professorship.

Scar management needs defined concepts and an algorithm to restore functional and aesthetic units. After an unsuccessful conservative treatment, surgical measures provide a vast spectrum of ...possibilities for remediation. The spectrum of possibilities consists of excision and Z-plasty, regional flaps, vascularized pedicled flaps, tissue expansion, and finally free tissue transfer. Severe scarring and highly destructed tissues with inferior functional and aesthetic units can be effectively treated with radical excision and free flap reconstruction. The complexity of flap architecture and tissue qualities allows for an individualized approach. Specific attention should be paid to the long-term consequences of severe scarring with progressive loss of functionality.
We worked out the most common surgical approaches and treatment algorithm for a stepwise and effective approach. Part of this algorithm is a seven-step surgical approach.
This article provides modern plastic and reconstructive surgery concepts with an algorithm for scar management.
The treatment of scars follows an algorithm with the level of complexity of techniques adjusted to the individual case and the conditions. Disabilities induced by scarring can lead to further functional loss. In these cases, surgical strategies have to be considered.
The use of social media such as Facebook, YouTube and Instagram is becoming an integral part of communication in plastic and aesthetic surgery. The potential reach provides significant opportunities ...to share information and reach patients. It must therefore be increasingly considered as a modern tool for a new form of publication and as a data and knowledge bank. This work aims to investigate the leading YouTube channels of German plastic and aesthetic surgeons with a view to reach, characteristics and topic focus.
All leading German YouTube channels of specialists in plastic and aesthetic surgery were evaluated. The analysis was based on key figures (country ranking, number of uploads, reach with total views, daily new subscribers; association with university hospital, non-university hospital, private practice) and content with a consecutive classification of the topics of the most successful videos.
With the keyword "plastic surgery", 376 German channels were identified, with 8 channels meeting the inclusion criteria. The most successful channels reached a median of 1.342.017 views (IQR 745.455-2.550.682). The daily views on the channels amount to a median of 718 views per channel (IQR 272-1.086). From a total of 290 of the most successful videos, 87% were about aesthetic procedures (n=253). A percentage of 87.5% (7/8) of the most successful channels were from plastic and aesthetic surgeons in private practice.
The platform YouTube offers an enormous potential of reach for knowledge transfer and marketing. It is primarily used by aesthetic surgeons and here mainly by those from the private practice sector. There is still a lot of potential for expansion regarding the representation of university plastic and aesthetic surgery with all its fields such as reconstruction, hand surgery and burn surgery on this platform.
Severe hand trauma, leading to extensive skeletal and tissue defects, requires plastic surgical reconstruction of the highest level aiming at maximizing function and aesthetics. The intention of this ...study was to investigate clinical parameters and resource consumption connected with severe hand injuries, with specific emphasis on a follow-up evaluation of quality of life after the reconstruction process.
In this retrospective study, we evaluated patients with severe hand injuries from 2013 to 2016 who had completed surgical and non-surgical treatment. Measures included total period of therapy (TPT) in days, total duration of operations including anesthesia (TOA), total duration of all operations (TO), and total number of operations (TNO). We also determined total inpatient stay (TIS), total number of clinic presentations with interventions (TNPI), initial hand injury severity score (iHISS), and inpatient proceeds (IPP) in Euros (€). Correlation was assessed between iHISS and TOA, TNO, and TIS. Finally, these patients were reexamined in a follow-up inquiry and the life quality was assessed with the five-level version of the EuroQol five-dimensional (EQ-5D) descriptive system (EQ-5D-5L).
We analyzed 12 patients with an average age of 44 years (min. 24 years, max. 75 years). Patients receiving reconstructive surgery experienced median (
) TPT of 175 days interquartile range (IQR), 51-499, TOA of 13 h (IQR, 6-37), TO of 9 h (IQR, 4-25), and TNO of 5 (IQR, 3-11). Further, the patients' median TIS was 22 days (IQR, 9-86), TNPI was 4 (IQR, 2-8), and iHISS was 77 (IQR, 44-162). The median IPP was 14.595 € (IQR, 5.541-33.709 €). IHISS was positively correlated with Pearson's r for TIS (0.817), TOA (0.857), and TNO (0.871). The EQ-5D-5L index value resulted in a high level of life quality with a median of 0.898 (min. 0.8, max. 1).
Severe hand injuries are related to high efforts for surgical and functional reconstructions, which result in high quality of life measured with the EQ-5D-5L assessment. However, for a defined collective of patients, myoelectric prosthetic functional replacement should be considered. Further studies are necessary to examine functional outcomes and quality of life after bionic prosthetic replacement. Also, a bionic reconstruction score to define hard criteria for taking an acute treatment decision is necessary.
In the field of plastic and aesthetic surgery, continuous international publication is seen annually. However, the publication output is not regularly assessed for its level of evidence. In view of ...the strong publication activity, a regular assessment of the evidence level of the current publication years is reasonable and was the objective of this work.
We evaluated the Journal of Hand Surgery/JHS (European Volume Journal), the journal Plastic and Reconstructive Surgery/PRS and the journal Handchirurgie, Mikrochirurgie und Plastische Chirurige/HaMiPla from January 2019 to December 2021. The authors' affiliation, the type of publication, the number of patients examined and the level of evidence with existing conflicts of interest were considered.
A total of 1341 publications were evaluated. Of these, 334 original papers were published in JHS, 896 in PRS, and 111 in HaMiPla. The largest share were retrospective papers (53.5%, n=718). The further distribution was as follows: 18% (n=237) clinical prospective papers, 3.4% (n=47) randomised clinical trials (RCT), 12.5% (n=168) experimental papers and 6.5% (n=88) anatomic studies. The distribution of evidence levels of all studies was as follows: Level I: 1.6% (n=21), Level II: 8.7% (n=116), Level III: 20.3% (n=272), Level IV: 25.2% (n=338), Level V: 2.3% (n=31). In 42% (n=563) of the papers, there was no indication of the level of evidence. Most level I evidence was from university hospitals (n=16) in 76.2% (χ²-test 0.619, >0.05, 95% confidence interval).
Although RCTs are inappropriate for many surgical questions, well-designed and conducted cohort or case-control studies could improve the evidence base. Many of the current studies tend to be retrospective and do not have a control group. Researchers in the field of plastic surgery should consider using a cohort or case-control design when an RCT is not feasible.
Background
Severe hand injuries significantly limit function and esthetics of the affected hand due to massive trauma in skeletal and soft tissues. Surgical reconstruction is often unsatisfactory, so ...bionic prostheses are a consideration. However, assessment of functional outcomes and quality of life after surgical reconstruction to guide clinical decisions immediately after injury and in the course of treatment remain difficult.
Methods
We conducted a prospective follow-up analysis of patients with severe hand injuries during 2016–2018. We retrospectively evaluated initial trauma severity and examined current functional status, quality of life, general function, and satisfaction in everyday situations of the hand. We also developed a novel Hand Bionic Score to guide clinical recommendation for selective amputation and bionic prosthesis supply.
Results
We examined 30 patients with a mean age of 53.8 years and mean initial severity of hand injury (iHISS) of 138.4. Measures indicated moderate quality of life limitations, moderate to severe limitation of overall hand function, and slight to moderate limitation of actual hand strength and function. Mean time to follow-up examination was 3.67 years. Using the measured outcomes, we developed a Hand Bionic Score that showed good ability to differentiate patients based on outcome markers. Appropriate cutoff scores for all measured outcome markers were used to determine Hand Bionic Score classifications to guide clinical recommendation for elective amputation and bionic prosthetic supply: < 10 points, bionic hand supply not recommended; 10–14, bionic supply should be considered; or > 14, bionic supply is recommended.
Conclusions
While iHISS can guide early clinical decisions following severe hand injury, our novel Hand Bionic Score provides orientation for clinical decision-making regarding elective amputation and bionic prosthesis supply later during the course of treatment. The score not only considers hand function but also psychological outcomes and quality of life, which are important considerations for patients with severe hand injuries. However, future randomized multicenter studies are needed to validate Hand Bionic Score before further clinical application.
Level of evidence: Level III, risk/prognostic study.
Industry funding of research studies can cause the results in the field of plastic, reconstructive and aesthetic surgery to be biased towards the sponsors. This paper aims to review randomised ...clinical trials (RCTs) published by leading international journals in plastic, reconstructive and aesthetic surgery with respect to characteristics and possible industry-friendly conclusions in favour of those funding the study.
Characteristic data and funding of RCTs published by leading international plastic surgery journals from January 2010 to January 2022 were evaluated. The studies were categorised based on their thematic focus and the results in light of the existing funding.
A total of 381 RCTs were included in the analysis, 68.5% of which were from a university (n=261). The larger proportion of studies did not disclose any information about the research funding. While 26% (n=98) of the studies analysed were funded by companies, 9.7% (n=37) were funded by universities/the government (p<0.05, 95% confidence interval). The overall focus of private clinics was aesthetics (n=32). Generally, the topic aesthetics (n=153) was funded by industry in 28 of 100 cases (28% industry/private sponsors compared with 9% university/government). Regarding reconstruction/burns/hand surgery, 9.2% of studies were funded by companies/private sponsors. Funding for research by university-based institutions was industry-sponsored in 25% (n=64) of cases. Regarding industry-sponsored studies, 73% (n=71) of the results were product-friendly in their conclusion (p<0.05, 95% confidence interval) and placed their thematic focus on therapeutic drug/product application (n=50, 75%).
In terms of funding, industry and private sponsors take a leading role both in reconstruction and aesthetics. Nonetheless, the majority of the evaluated studies were not financed by the private sector. In cases where the research was funded by private companies, the results were significantly in favour of the product. Aesthetics as a focus is currently more frequently funded by industry than reconstruction, burn, and hand surgery.
Fibrin glue (FG) can be applied in several surgical procedures at wound closure to reduce postoperative complications such as hematoma formation and wound impairment. The purpose of this study is to ...assess these preventive surgical benefits in Dupuytren's disease of the hand.
We performed a monocentric retrospective cohort study. All patients who underwent selective aponeurectomy for Dupuytren's disease between 2010 and 2020 were included. Patients were divided into two groups: either receiving or not receiving FG. The primary outcome variables were postoperative bleeding, wound healing impairment, and further pooled postoperative complications.
One hundred and thirty-three patients were included in the analysis of which 108 patients were treated with FG, while 24 did not. There was no statistically significant difference in outcomes regarding postoperative bleeding, infections, or revision surgery. However, in the group receiving FG, there was a tendency toward higher wound healing impairment (13%, p = 0.07). The FG group showed a significantly higher pooled complication rate (18.5%, p < 0.02). Complication in general increased with higher Tubiana classification and number of resected cords. Smoking tripled the risk of impaired wound, while cardiovascular comorbidities increased postoperative bleeding by the factor of 11.
FG did not show a preventive outcome regarding bleeding. The FG group had a tendency for a higher wound healing incidence. Smoking and arterial hypertension correlated with a higher postoperative complication rate. The overall incidence of complications was higher in the FG group. The quality of the surgical intervention as well as accurate hemostasis cannot be corrected by the application of FG.
Severe soft tissue damage with destruction of the dermis requires plastic reconstructive treatment. For multimorbid patients or patients unable to undergo major reconstructive surgery, use of dermal ...substitutes, such as a collagen-elastin matrix (CEM) with a split-thickness skin graft (STSG), instead of local or free flap surgery, may be a valid and easy treatment option. We aimed to investigate and compare the outcomes and rate of successful defect reconstruction using CEM plus STSG, using either a one-step approach (simultaneous CEM and STSG) or a two-step approach (CEM and negative wound pressure therapy (NPWT), with secondary STSG transplantation).
A single-centre, retrospective follow-up study of patients who had received CEM was conducted. Wounds had been treated with an STSG transplantation covering a CEM (MatriDerm, MedSkin Solutions Dr. Suwelack AG, Germany). Previous attempts at wound closure with conventional methods had failed in the selected patient population, which would usually have resulted in flap surgery.
Overall, 46 patients were included (mean age 60.9±20.0 years), with a total of 49 wound sites. We analysed 38 patients with wounds that did not require flap coverage; 18 patients received the one-step approach and 20 patients received the two-step approach. The mean follow-up in these patients was 22±11.5 months, and one patient was lost to follow-up. Overall, 29 (78.4%) wounds remained closed. Wounds which did not successfully heal were related to comorbidities, such as diabetes, alcohol misuse and smoking. Using the one-step approach, long-term defect coverage was achieved in 13 (76.5%) wounds and 16 (80.0%) wounds were closed using the two-step approach. However, there was no statistically significant differences between the one- or two-step approaches regarding the rate of development of a wound healing disorder.
Wound closure was achieved in 38 complex wounds using CEM plus STSG, while 11 wounds needed secondary flap coverage. In the flap-free wounds, there were no statistically significant differences between the one-step versus two-step approach. Using a simple defect reconstruction algorithm, we successfully used CEM plus STSG to treat complex wounds.
