In recent years a number of methodological developments have improved the opportunities to study human tendon. Microdialysis enables sampling of interstitial fluid in the peritendon tissue, while sampling of human tendon biopsies allows direct analysis of tendon tissue for gene- and protein expression as well as protein synthesis rate. Further the (14)C bomb-pulse method has provided data on long-term tissue turnover in human tendon. Non-invasive techniques allow measurement of tendon metabolism (positron emission tomography (PET)), tendon morphology (magnetic resonance imaging (MRI)), and tendon mechanical properties (ultrasonography combined with force measurement during movement). Finally, 3D cell cultures of human tendon cells provide the opportunity to investigate cell-matrix interactions in response to various interventions.

Background: There are various options of tendon transfer according to the different types of irreparable rotator cuff tears (IRCTs). However, there were no clear treatment options for the IRCTs involving the anterior, superior and posterior rotator cuff tears (global IRCTs). Latissimus dorsi and teres major (LDTM) could be transferred anteriorly or posteriorly in global IRCTs.

Introduction: In November 2018, the European Medicines Agency (EMA) restricted the use of fluoroquinolones (used by mouth, injections or inhalation) in the context of a referral due to long-lasting and potentially irreversible adverse drug reactions (ADRs). Fluoroquinolones should no longer be used to treat mild or moderate bacterial infections unless other antibacterials cannot be used.

Objectives: The first aim of our study was to analyze whether in the period before compared with after the referral the characteristics of spontaneous ADR reports related to fluoroquinolones differed and whether specific ADRs were more frequently reported for fluoroquinolones compared with cotrimoxazole.

Anterior cruciate ligament reconstruction aims to improve knee stability and range of motion. The AperFix system consists of polymer components, and fixed-loop fixation is an established endoscopic technique. Our aim in this study was to compare the long-term clinical and radiological results of AperFix and fixed-loop fixation and to prove that the long-term results of the AperFix fixation method are at least as good as those of the fixed loop device.

The digastric muscle is a suprahyoid muscle that is composed of an anterior belly and a posterior belly, which originate from the first and second pharyngeal arches, respectively, and they are innervated by the nerves of these arches. The digastric muscles are involved in the elevation of the hyoid bone and depression of the mandible during mastication, speech, and swallowing. In this report, we present the rare case of bilateral accessory anterior belly of the digastric muscles (ABDMs) that originated from the digastric fossa, medial to the anterior bellies.

Coronavirus disease (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that primarily affects the respiratory system but can also lead to neurological complications such as Guillain-Barré syndrome (GBS). This case report describes an eight-year-old boy with COVID-19-associated GBS involving multiple cranial nerves (third, seventh, and ninth) without pulmonary symptoms. The patient initially presented with flu-like symptoms along with right facial paralysis, which progressed to bilateral facial paralysis, limb weakness, and sensory loss.
