The purpose of this retrospective study was to evaluate the long-term results with a minimum of ten years follow-up of primary Bologna-Oxford (BOX) TAA.
Between December 2004 and December 2009, 80 patients (82 ankles) underwent a primary BOX TAA performed by a single senior surgeon, expert in foot and ankle surgery. Pain and functional outcomes were analysed using Visual Analogue Scale (VAS) for pain, American Orthopaedic Foot & Ankle Society (AOFAS) scoring system, Foot Functional Index Disability and Pain (FFI-Disability, FFI-Pain) score for comparative analysis.
A total of 52 patients (54 implants) in a cohort of 80 (82 implants) were examined at a minimum tenyears follow-up. Twenty implants out of 54 underwent implant failure (37 %) and 34 patients were enrolled in the present study. IU1 The mean VAS for pain decreased significantly from 8.5 ± 1.2 to 2.9 ± 2.2 (p<0.01) and the mean AFOAS score changed from 28.6 ± 11.8 pre-operatively to 72.7 ± 16.9 (p<0.01) at last follow-up. Ninety-seven percent was satisfied with a mean FFI-Disability score that improved from 77.6 ± 19.3 to 26.7 ± 25.4 (p<0.01) and FFI-Pain score that decreased from 76.2 ± 14.2 to 31.4 ± 25.6 (p<0.01). We calculated post-operative alignment using alpha, beta and gamma angles with no difference at long-term follow-up. The survival rate of the implant was 66% at tenyears of follow-up.
Our data suggest that BOX TAA is an implant with a good patient satisfaction rate at long-term follow-up; therefore, it is a valid option to increase the quality of life in subjects with end-stage osteoarthritis; however, long-term survivorship is unsatisfactory when compared to modern knee and hip implant.

The case report of a five hour old newborn addresses the trauma management concerning diagnostics, therapy, and post-operative care of a deep periocular soft tissue injury. The pattern of injury consisted of full thickness wounds of the medial and lateral lid margins, opening of the superior conjunctival fornix, and penetration of Tenon's capsule. The reconstruction was performed layer by layer while an autostable monocanaliculonasal lacrimal intubation was inserted.
Despite considerable advances in laryngological research, there is still aplethora of (benign) vocal fold pathologies that cannot be treated causally. This is due to the limited accessibility and sensitive microarchitecture of the vocal folds, which cannot be investigated at acellular level. Consequently, current pathophysiological knowledge is frequently based on macroscopic findings. The impact of interventions is mainly evaluated endoscopically or via indirect diagnostic methods.
The aim of this article is to discuss state-of-the-art biotechnological methods used in laryngological research, illustrated by practical examples.
In recent years, animal and in vitro experiments have significantly contributed to acontinuous expansion of knowledge in this field, particularly regarding vocal fold inflammation and scar formation. Vocal fold fibroblasts, the most important cellular component of the lamina propria, can be accredited acentral role in these processes.
Our knowledge regarding macroanatomy and mas of knowledge for subsequent clinical studies.
The skull base is asurgically complex unit and is often only accessible via combined access routes. Newly developed surgical techniques using microsurgical visualization procedures and active instruments ("powered instruments") as well as multiport accesses enable new, less traumatic surgical corridors. This requires close interdisciplinary cooperation between ENT and neurosurgeons. Currently established access routes to the central skull base are systematized based on the authors' own clinical experience, and discussed in relation to the entity and the current study situation.
Aretrospective, qualitative, and descriptive evaluation of the surgical reports of patients with pathologies of the central skull base who were jointly treated by neurosurgery and otorhinolaryngologic/head and neck surgery between 2006 and 2019 was performed.
The surgical access routes to the central skull base can be categorized as so-called multiport access routes, partly also in combination, as follows transnasal-transsphenoidal, subfrontal, subtemporal, transzygomatic, transpterygonal, transpetrous, translabyrinthine, and suboccipital. The choice of access route was based on the location and type of pathology, its inflammatory or space-occupying (benign or malignant tumor) nature, and the possibilities of functional preservation and complete removal.
Due to the complexity of central skull base structures, the different tumor entities, and the required expertise of different medical specialties, surgery of the central skull base remains achallenge and should only be performed at special competence centers certified according to the criteria of the German Society of Skull Base Surgery.

Protein arginine methyltransferase 4 (PRMT4), a member of the type I PRMT family, is involved in various biological activities, but its role in endothelial cell (EC) remains elusive. Here, we aimed to investigate the role of PRMT4 in ischemic angiogenesis and explore the possible underlying mechanism. We found that PRMT4 was upregulated in ischemic muscles, and VEGF treatment potentiated its expression in ECs. In vitro, adenovirus-mediated PRMT4 overexpression promoted, while its gene disruption inhibited, EC proliferation, migration, and tube formation. In an in vivo hindlimb ischemia model, forced expression of PRMT4 in ECs showed accelerated blood flow recovery and increased capillary density, whereas its knockdown exhibited the opposite effect. Mechanistically, PRMT4 activated the transcription of VEGF via the interaction with Y-box binding protein-1 (YB1), leading to accelerated angiogenesis.
