BACKGROUND: Shoulder dislocation is often the first symptom of Ehlers-Danlos syndrome (EDS). Whether it occurs in early-onset EDS is unknown. In most cases, surgical failure leads to the diagnosis. We aimed to determine whether clinical symptoms can signal the presence of EDS at a first dislocation. MATERIALS AND METHODS: In this retrospective study, we analyzed clinical and radiologic data for 27 patients with EDS and shoulder instability and a control population of 40 consecutive non-EDS patients undergoing surgery for an unstable shoulder...

AIM: Preterm birth is the world's leading cause of neonatal death. Unfortunately, the pathophysiology of preterm birth remains poorly understood. Sjögren-Larsson syndrome is a rare, neurometabolic disorder caused by a fatty aldehyde dehydrogenase deficiency. A majority of patients with Sjögren-Larsson syndrome is born preterm. METHODS: Data of all known Dutch patients with Sjögren-Larsson syndrome and all cases reported in literature were analyzed to learn from preterm birth in context of this rare disease...

Giant aortic aneurysm is defined as an aneurysm of the aorta of greater than 10 cm in diameter. This rare condition is associated with a high risk of morbidity and mortality and it may lead to fatal complications such as rupture and/or dissection if not managed with proper surgical planning and expertise. Other than atherosclerosis, the main causes of giant ascending aortic aneurysms include Marfan and Ehlers-Danhlos syndromes. Herein we report on a young male patient who had had an aortic valve replacement five years earlier due to a bicuspid aortic valve leading to aortic failure, accompanied by aortic coarctation...

PURPOSE OF REVIEW: Joint hypermobility is a common, although largely ignored physical sign. Joint hypermobility is often asymptomatic but may be a feature of an underlying genetic disorder with systemic manifestations. The present article presents a comprehensive approach to considering joint hypermobility and clinically related issues in children and adults. RECENT FINDINGS: Ehlers-Danlos syndrome (EDS) is an umbrella term for various Mendelian connective tissue disorders sharing joint hypermobility, skin hyperextensibility, and tissue fragility...

The great radiation in the infraorder Cyclorrhapha involved several morphological and molecular changes, including important changes in anterior egg development. During Drosophila oogenesis, exuperantia (exu) is critical for localizing bicoid (bcd) messenger RNA (mRNA) to the anterior region of the oocyte. Because it is phylogenetically older than bcd, which is exclusive to Cyclorrhapha, we hypothesize that exu has undergone adaptive changes to enable this new function. Although exu has been well studied in Drosophila, there is no functional or transcriptional information about it in any other Diptera...

M R Ehlers, R M Todd
Addiction is increasingly discussed asa disorder of associative learning processes, with both operant and classical conditioning contributing to the development of maladaptive habits. Stress has long been known to promote drug taking and relapse and has further been shown to shift behavior from goal-directed actions towards more habitual ones. However, it remains to be investigated how acute stress may influence simple associative learning processes that occur before a habit can be established. In the present study, healthy young adults were exposed to either acute stress or a control condition half an hour before performing simple classical and operant conditioning tasks...

Background: More and more institutions worldwide and in German-speaking countries are developing and establishing interprofessional seminars in undergraduate education of health professions. In order to evaluate the different didactic approaches and different outcomes regarding the anticipated interprofessional competencies, it is necessary to apply appropriate instruments. Cross-cultural instruments are particularly helpful for international comparability. The Interprofessional Education working group of the German Medical Association (GMA) aims at identifying existing instruments for the evaluation of interprofessional education in order to make recommendations for German-speaking countries...

REVIEW
Angela M Mabb, Michael D Ehlers
The activity-regulated cytoskeleton-associated protein (Arc) is a neuron-expressed activity regulated immediate early gene (IEG) product that is essential for memory consolidation and serves as a direct readout for neural activation during learning. Arc contributes to diverse forms of synaptic plasticity mediated by the trafficking of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. Notably, Arc protein expression abruptly increases and then rapidly decreases following augmented network activity...

BACKGROUND: Chordomas arise from remnants of the notocord and occur throughout the neuroaxis. En bloc resection of chordomas can prove especially challenging in the upper cervical spine secondary to the unique structural anatomy and intimate relationship to the vertebral arteries and spinal cord. CASE DESCRIPTION: We describe the resection of a C2-3 chordoma in a 55 year old female in two stage fashion with preservation of the vertebral arteries. First a posterior instrumented fusion and removal of the posterior elements was performed, followed by an anterior transmandibular en bloc resection with cage reconstruction with kick-plate support achievable with off-the-shelf products...

Biochemistry and physiology teachers from veterinary faculties in Hannover, Budapest, and Lublin prepared innovative, computer-based, integrative clinical case scenarios as optional learning materials for teaching and learning in basic sciences. These learning materials were designed to enhance attention and increase interest and intrinsic motivation for learning, thus strengthening autonomous, active, and self-directed learning. We investigated learning progress and success by administering a pre-test before exposure to the virtual patients (vetVIP) cases, offered vetVIP cases alongside regular biochemistry courses, and then administered a complementary post-test...

The reactivity of the geminal phosphinoborane tBu2PCH2BPh2 towards terminal alkynes, nitriles and nitrilium salts is investigated. Terminal alkynes react via C-H bond splitting (deprotonation) resulting in the formation of phosphonium borates. In contrast, both nitriles and nitrilium salts undergo addition reactions resulting in the formation of five-membered heterocycles. All compounds were characterized by multinuclear NMR spectroscopy, and single-crystal X-ray structure determinations. Insight into the reaction mechanisms was gained by DFT calculations...

Acute aortic dissection is a rare but life-threatening condition with a lethality rate of 1 to 2% per hour after onset of symptoms in untreated patients. Therefore, its prompt and proper diagnosis is vital to increase a patient's chance of survival and to prevent grievous complications. Typical symptoms of acute aortic dissection include severe chest pain, hypotension or syncope and, hence, mimic acute myocardial infarction or pulmonary embolism. Advanced age, male gender, long-term history of arterial hypertension and the presence of aortic aneurysm confer the greatest population attributable risk...

Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome-Hypermobility Type (JHS/EDS-HT) is a complex and multisystemic condition which significantly impacts on a person's health and well-being and is challenging for health professionals (HPs) to manage. People with JHS/EDS-HT and HPs recognise the individual nature and the complexities of the condition. There is a requirement to understand the condition within the context of the individual human dimensions of illness and healing. The aim of this paper is to explore the management of this condition using a theoretical model referred to as the Humanisation Framework...

The immunological mechanism(s) of action whereby teplizumab preserves C-peptide levels in the progression of patients with recent onset type 1 diabetes (T1D) is still not well understood. In the present study, we evaluated the kinetics of T cell modulation in peripheral blood following two 14-day courses of teplizumab therapy one year apart in recent onset T1D participants in the AbATE clinical trial. Transient rises in PD-1+Foxp3+ Treg and potentially anergic (CD57-KLRG1-PD-1+) cells in the circulating CD4 T cell compartment were paralleled by more profound increases in circulating CD8 T cells with traits of exhaustion (CD57-KLRG1+PD-1+, TIGIT+KLRG1+, and persistent down-modulation of CD127)...

OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) across the world often leave clinicians with little or no choice of treatment options. The multi-drug efflux (MDE) genes are bacterial survival mechanisms responsible for the pumping out of antibiotics and other biocides from the cytoplasm. Whilst effort is being made in the development of antibiotic adjuvants such as efflux pumps inhibitors, information is needed on the diversity of these MDEs in the circulating S. aureus and on the growth dynamics of the clinical isolates in response to antibiotics is not regularly examined...
