Segmentation of the iliac crest from CT-data for virtual surgical planning of facial reconstruction surgery using deep learning.

Background And Objectives: For the planning of surgical procedures involving the bony reconstruction of the mandible, the autologous iliac crest graft, along with the fibula graft, has become established as a preferred donor region. While computer-assisted planning methods are increasingly gaining importance, the necessary preparation of geometric data based on CT imaging remains largely a manual process. The aim of this work was to develop and test a method for the automated segmentation of the iliac crest for subsequent reconstruction planning.

Evaluation of zirconia implants in fibula and deep circumflex iliac artery flaps: a prospective 1.5-year follow-up study.

Objectives: Follow-up results of modern zirconia implants inserted in fibula free and deep circumflex iliac artery (DCIA) flaps with fixed dentures are scarce. This study aimed to evaluate crestal bone changes and the survival rate of zirconia implants for up to 1.5 years of prospective follow-up.

Incorporating patient-specific prior clinical knowledge to improve clinical target volume auto-segmentation generalisability for online adaptive radiotherapy of rectal cancer: A multicenter validation.

Background & Purpose: Deep learning (DL) based auto-segmentation has shown to be beneficial for online adaptive radiotherapy (OART). However, auto-segmentation of clinical target volumes (CTV) is complex, as clinical interpretations are crucial in their definition. The resulting variation between clinicians and institutes hampers the generalizability of DL networks.

Influence of antiplatelet medication and anticoagulation therapy after dental extractions on hospitalization: a retrospective 10-year study.

Background: The aim of this retrospective study was to identify high-risk dental extraction patients and the timing of postoperative hemorrhage to evaluate whether preventive hospitalization should be considered in patients on antiplatelet medication (AP) or anticoagulants.

Methods: Our study included 1595 procedures; 1319 were conducted under monotherapy (Group I: AP; Group II: indirect oral anticoagulant [IAC]; Group III: direct oral anticoagulant [DOAC]) and 276 under dual therapy (Group IV: double AP; Group V: AP and IAC; Group VI: AP and DOAC). We evaluated the incidence, frequency and timing of hemorrhage, hospitalization rate, and treatment of bleeding incidents.

Ehlers-Danlos syndromes and related disorders: diagnostic challenges and the need for an interdisciplinary patient care in Germany.

Unlabelled: (215 words): Introduction: Ehlers-Danlos syndromes (EDS) represent a group of heritable connective tissue disorders characterised by skin hyperelasticity, joint hypermobility and generalized tissue fragility. Many patients remain undiagnosed years after initial symptoms and an accurate diagnosis is difficult despite all efforts. Currently, Germany lacks a patient registry and a specialised EDS centre.
