Periprosthetic joint infections (PJIs) are dramatic complications after primary total joint arthroplasty. Despite increasing research in this field, the diagnosis, classification, and management of PJI remain a challenge. This is mainly due to the heterogenous clinical presentation of PJI in clinical routine and patient-related factors as secondary diagnosis and periprosthetic tissue condition. The early detection of PJI is essential for adequate treatment. However, there is no definition for PJI with 100 % sensitivity or a negative predictive value. This can potentially lead to a delayed or missed diagnosis of PJI. Furthermore, the surgical and antibiotic treatment is among the most discussed topics in PJI literature. There is no international consensus on the treatment of different PJI entities. Concludingly many aspects of PJI diagnostics and treatment remain controversially discussed and current studies are only comparable to a limited extent due to study heterogeneity and limited comparability.

Introduction: Anomalies of jaw position and shape affect approximately 10 % of the population. They can have a significant impact on quality of life, which is why the continuous improvement of therapeutic approaches is a key concern in oral and maxillofacial surgery. The aim of this narrative review article is to examine the development of orthognathic surgery in the context of traditional and innovative methods.

Content: A Pubmed-based selective literature search was performed considering literature predominantly from 2022 to 2023. Search terms were "orthognathic surgery" in combination with "virtual surgical planning" and "3D printing".

Summary: Depending on the extent of the existing anomalies, there are purely orthodontic or combined orthodontic-surgical treatment approaches. Technological innovations in particular are changing both the therapeutic approach and the planning of surgical treatment to an almost completely digital workflow. This change can lead to greater precision in treatment and more efficient planning, resulting in reduced costs and an overall improvement in clinical outcomes, including patient satisfaction.

Outlook: This study presents an overview of the field of orthognathic surgery and discusses developments and challenges for the future. With traditional approaches being time-consuming and prone to error digital technologies like VSP, AI and PSIs improve accuracy and efficiency, though challenges persist.

The treatment of severe burn injuries is an essential part of plastic-reconstructive surgery. Severe burned patients are treated in burn centers, which have highly specialized technical and personnel equipment. In addition to clear recommendations for prehospital management, intensive care therapy is usually required for extensive burn wounds. Shock therapy in burns primarily involves balanced fluid resuscitation according to hemodynamic monitoring, vasopressor support, pain management, temperature regulation, oxygen therapy, and comprehensive supportive care to stabilize the patient's condition. Surgical treatment is still based on wound debridement and the gold standard of autologous split-thickness skin grafting. Besides skin transplantation, surgical management of burns may also involve the application of various topical therapies to promote wound healing, reduce pain, and prevent infection. These therapies may include antimicrobial dressings, skin substitutes, growth factors, or specialized wound care products. Once the acute treatment has been completed, multidisciplinary rehabilitation treatment takes place, which begins in the acute hospital and continues in the outpatient and inpatient rehabilitation areas. Surgical treatment of the secondary complications of burns and scars is also an important component of burn care. Comprehensive knowledge of the various components and players involved in the care of severely burned patients is, therefore, required in order to achieve the best possible outcome for the patient.

Introduction: Abdominal surgery in children may disrupt normal gut function, necessitating prolonged fasting, which can lead to complications such as dehydration and nutritional deficits. Early enteral nutrition (EEN) after surgical procedures can enhance wound healing, prevent malnutrition, and expedite recovery. Although concerns exist regarding the risk of complications associated with EEN, current evidence suggests that it is not linked to increased perioperative complications.

Content: This scoping review provides an overview of the role of EEN in pediatric abdominal surgery, exploring its benefits and risks within the context of recent literature from 2021 to 2024. A systematic literature search was conducted using the PubMed database in April 2024 and the identified studies were compared. The search revealed 586 results, wherefrom eight studies (three systematic reviews and five clinical studies) fulfilled the inclusion criteria. Five studies were added since 2021. Overall, EEN may reduce the length of hospital stay, time to full oral intake, and return of bowel function. It does not seem to increase the rate of anastomotic leakage. EEN is associated with lower rates of surgical site infections and wound dehiscence as well as fewer septic complications. One study showed an increase in nausea/vomiting and abdominal distension in the EEN group, which did not lead to further complications.

Summary and outlook: Current evidence suggests that EEN after abdominal surgery in pediatric patients is not associated with a higher rate of complications. In fact, EEN seems to be beneficial and lead to improved patient outcomes and shorter hospital stays. Emphasis on patient and parent comfort, individualized feeding initiation based on clinical factors, and standardized postoperative feeding protocols are recommended to optimize outcomes in pediatric abdominal surgery.

Objectives: Due to increasing workload and rising expectations for both undergraduate and speciality training in medicine, teaching in a clinical environment can be challenging. The "Train the Trainer" course, developed by CAL (Chirurgische Arbeitsgemeinschaft Lehre, Deutsche Gesellschaft für Chirurgie (DGCH)), aims to assist clinical teachers in their task. This study investigates the effect the course has on participants' self-efficacy and teaching motivation.

Methods: Prior to attending the course, participants anonymously completed a 50-question pre-course questionnaire using standardised questions to gather information on biographical data teaching experience, and validated tools measuring teaching motivation and self-efficacy (PRE). Directly after completing the course, participants evaluated it using a 25-question post-course questionnaire (POST1). At least 12 months after the course, participants received a follow-up questionnaire (POST2) by mail. This 44-question form aimed to gather biographical data, review the teaching methods participants had used since their training, and reassess their teaching motivation and self-efficacy.

Results: Between June 2016 and October 2019, 20 TTT courses were held across six German medical faculties. Data were gathered from 241 participants. After the course, 182 POST2 questionnaires were mailed, 61 of which were returned (equals a 39 % return rate). The findings revealed significant increases in teacher self-efficacy (p=0.0025), identified regulation (p=0.0000), and career motivation (p=0.0044). In contrast, there was a significant decrease in introjected regulation (p=0.0048). When comparing the participants to a reference sample selected from literature, significant differences emerged in intrinsic motivation (p=0.0000) and amotivation (p=0.0025).

Conclusions: Course participants already showed strong intrinsic motivation and self-efficacy before taking the course. After completing it, their confidence to meet specific teaching demands based on their abilities had increased. Notably, changes in motivational dimensions identified and introjected regulation point towards a shift in motivational sources, indicating a more self-regulated approach towards participants' teaching activities. Further research is needed to determine how much of this change was due to course participation.

In microsurgery, many different imaging techniques are available in both flap and lymphatic surgery that all come with their own advantages and disadvantages. In flap surgery, CT angiography is considered as the gold standard. Among others, Doppler ultrasound, color Doppler ultrasound, ICG, and smartphone-based thermal cameras are valuable imaging techniques. In lymphatic surgery, photoacoustic imaging, laser tomography, contrast-enhanced magnetic resonance imaging, and high frequency ultrasound stand available to surgeons next to the current standard of lymphoscintigraphy. It is crucial to know the advantages and disadvantages to various techniques and highly adviced to microsurgeons be capable of using a variety of them.
