[Augmented and virtual reality in surgery: fields of application and exploratory studies exemplified by VIVATOP : Perioperative surgical planning and intraoperative support].

Digital technologies, such as virtual and augmented reality (VR and AR) are mainly used in the preclinical and clinical phases in neurosurgery and orthopedics. In contrast, they are used less frequently in visceral surgery as the intraoperative deformation is challenging for the clinical use. The application of VR is used successfully particularly in education and training.

[Telemedicine and AI-supported diagnostics in the daily routine of visceral medicine].

Advances in telemedicine, exemplified by augmented reality (AR) and virtual reality (VR), are rapidly progressing. For instance, AR available over long distances has already been successfully utilized in crisis intervention, such as in war zones. The potential of telemedicine also appears promising in structurally weak areas or in the involvement of experts in emergency situations.

[From imaging to interaction with 3D models: technical aspects].

Augmented and virtual reality (AR and VR, respectively) are already being used or evaluated in some medical fields: however, the widespread application is still hampered by inconsistent and often confusing terminology, in particular for people who are not familiar with current developments. Additionally, the technical principles and requirements for its use are often insufficiently well known. This overview article therefore aims to clarify the most important terminology and presents the current technical state of the art, spanning from the requirements of medical imaging, through 3D models and the various forms of visualization to the interaction possibilities within VR and AR.

Mechanism and Management of Aorto-Esophageal Fistulation after Thoracic Endovascular Aortic Repair.

An aorto-esophageal fistula (AOF) is a pathological communication between the thoracic aorta and the esophagus. It can induce life-threatening hematemesis, which is unique among the other types of gastrointestinal hemorrhage in that the vomiting is bright red and represents an arterial bleed. Nevertheless, it is notable that over 70% of cases are associated with thoracic aortic aneurysms, particularly as a postoperative complication following open surgery, and arguably more so following endovascular repair.

[Pathological fractures of the extremities].

The diagnostics and treatment of pathological fractures of the extremities differ from the approach for conventional fractures. Metastases from breast, bronchial, renal cell and prostate cancer are the predominant cause. Typically, patients present at over 50 years old present after an inadequate trauma.

[Digital tools in primary total knee arthroplasty-Prevalence in the German-speaking region].

Background: Digital tools are being increasingly used worldwide in primary knee arthroplasty. This study aimed to analyze the utilization density of digital tools, the preferred alignment strategies, and the obstacles and benefits of implementing these technologies in German-speaking countries.

Materials And Methods: An online survey with 57 questions about digital tools in primary knee arthroplasty and their usage was conducted among members of the Arthroplasty Working Group (AE).

The Co-Occurrence of Medullary and Papillary Thyroid Carcinoma-A Literature Review Based on a Case Report.

The co-occurrence of medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC) is thought to be a rare phenomenon. Here, we present a patient undergoing surgery due to a suspected MTC. Histopathological workup confirmed the suspected diagnosis but also described an incidental PTC in the contralateral lobe with lymph node metastasis in the central cervical compartment.

Using mobile EEG to study auditory work strain during simulated surgical procedures.

Surgical personnel face various stressors in the workplace, including environmental sounds. Mobile electroencephalography (EEG) offers a promising approach for objectively measuring how individuals perceive sounds. Because surgical performance does not necessarily decrease with higher levels of distraction, EEG could help guide noise reduction strategies that are independent of performance measures.

Role of stimulus dose on neuropsychological functioning after electroconvulsive therapy in patients with major depressive disorder.

Introduction: Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from treatment-resistant depression but its use is often limited by the concern for cognitive side effects. This study examines the effect of ECT on autobiographical and verbal memory compared to a healthy control group and the impact of the mean stimulus dose on cognition after ECT.

Methods: Autobiographical and verbal memory were assessed in depressed patients and healthy controls before the first and within one week after the last ECT treatment.

Unusual presentation of PYGM gene mutation as late-onset McArdle disease with camptocormia: a case report.

Background: Glycogen storage disease type 5 (McArdle disease) leads to a deficiency in the activity of myophosphorylase resulting in an impaired glucose utilization. The disease can be caused by a variety of mutations in the PYGM gene, and its typical clinical manifestation is muscles weakness within the first three decades of life.

Case Presentation: In this case report we present the diagnostic work-up of a physically active 78-year-old Caucasian patient suffering from a 2-year history of progressive camptocormia including clinical, radiologic, histological, and genetic tests.

Comparison of eTEP and IPOM for ventral hernia surgery in the early postoperative period: a retrospective cohort study of a tertiary university centre.

Purpose: The extended totally extraperitoneal technique (eTEP) is a relatively new laparoscopic approach to address ventral hernias. Since this technique is not widely used yet, the literature regarding its efficacy and safety is limited, especially when compared to more established surgical techniques like intraperitoneal onlay mesh (IPOM). This study aimed at contributing to the expanding body of evidence for eTEP, by comparing the early outcomes of eTEP and IPOM surgeries for ventral hernias.

Classification of hallux valgus deformity-is there a standard?

Introduction: Hallux valgus deformity severity is one determent for the surgical procedure for hallux valgus (HV) correction. HV deformities are usually classified into mild/moderate/severe. The aim was to investigate the cut-off criteria used to classify HV deformity.

Patient-reported outcome measures in studies on hallux valgus surgery: what should be assessed.

Introduction: In recent years, there has been an increasing demand for patient-reported outcome measures (PROMs) to assess the outcome following orthopedic surgery. But, we are lacking a standard set of PROMs to assess the outcome of hallux valgus surgery. The aim of this study was to analyze the chosen patient rated outcome scores used in studies reporting on hallux valgus surgery.

Intracranial response to capmatinib after progression on crizotinib in a patient with exon 14 skipping non-small cell lung cancer-a case report.

Background: Capmatinib, a potent and selective tyrosine kinase inhibitor (TKI), holds promise as a therapeutic agent due to its potentially elevated intracranial efficacy in metastatic non-small cell lung cancer (NSCLC) patients harboring exon 14 skipping alterations in (MET Proto-Oncogene). This study aims to evaluate a targeted therapeutic approach to an exon 14 skipping (METex14) advanced NSCLC patient that progressed on Crizotinib and developed off target resistance alteration in PIK3CA.

Case Discription: We present a case of advanced METex14 NSCLC patient wherein central nervous system (CNS) relapse occurred post complete surgical resection and remission of the lung tumor under first-line crizotinib treatment.

Early monitoring of inlay wear after total knee arthroplasty on plain radiographs using model-based wear measurement.

Wear of the ultra-high molecular-weight polyethylene (UHMWPE) component in total knee arthroplasty contributes to implant failure. It is often detected late, when patients experience pain or instability. Early monitoring could enable timely intervention, preventing implant failure and joint degeneration.

Patients' and caregivers' perception of multidimensional and palliative care in amyotrophic lateral sclerosis - protocol of a German multicentre study.

Introduction: Amyotrophic lateral sclerosis (ALS) is an inevitably fatal condition that leads to a progressive loss of physical functioning, which results in a high psychosocial burden and organizational challenges related to medical care. Multidimensional and multiprofessional care is advised to meet the complex needs of patients and their families. Many healthcare systems, including Germany, may not be able to meet these needs because non-medical services such as psychological support or social counselling are not regularly included in the care of patients with ALS (pwALS).
