ans should be familiar with these anatomic variants to enhance its recognition, understanding that a muscular variant is rarer than previously reported, but historically can serve as a potential source of clinical symptomatology and could be encountered during physical examination or wrist surgery.
Heart failure (HF) is common in older people. The diagnosis of HF, however, is difficult in older subjects, especially in settings without direct access to further diagnostics. The type of blood pressure response during the performance of aValsalva maneuver has been suggested as an easily applicable bedside test to detect HF; however, the reliability of this maneuver and the association with HF is unknown in geriatric patients.

This study included 89 patients admitted for geriatric rehabilitation. Systolic blood pressure was taken while the patient performed aValsalva maneuver. The systolic blood pressure response was classified as sinusoidal (typeA), absent overshoot (typeB) or square pattern (typeC). To test interrater reliability systolic blood pressure response was evaluated independently by two investigators. The procedure was repeated after 1h to estimate test-retest reliability. Both investigators were blinded to the results of the other. Interrater reliability and test-retest reliability were calc The type of response is associated with the NT-pBNP plasma level.The COVID-19 (coronavirus disease 2019) pandemic has caused a worldwide economic and clinical disaster. During times with the highest infection rates, clinical practice for all specialties including urology shifted to the emergency setting. Proper patient selection needs to be done to avoid infection; however, there is a fine line between postponing surgery and negatively affecting the outcome of the disease to be treated. The rapid integration of telemedicine has helped to keep up outpatient medical care, interdisciplinary communication and education. Nevertheless, surgical education of urological residents initially fell behind. The real impact of the COVID-19 pandemic on urology will probably first be seen after the awaited vaccine and control of COVID-19.Hypoxia at high altitudes can constrain the ability of endotherms to maintain sufficient rates of pulmonary O2 transport to support exercise and thermogenesis. Hypoxia can also impede lung development during early post-natal life in some mammals, and could thus accentuate constraints on O2 transport at high altitude. We examined how these challenges are overcome in deer mice (Peromyscus maniculatus) native to high altitude. Lung structure was examined in highland and lowland populations of deer mice and lowland populations of white-footed mice (P. leucopus; a congener restricted to low altitude) that were bred in captivity. Among mice that were born and raised to adulthood in normoxia, highland deer mice had higher alveolar surface density and more densely packed alveoli. The increased alveolar surface density in highlanders became fully apparent at juvenile life stages at post-natal day 30 (P30), after the early developmental period of intense alveolus formation before P21. Alveolar surface density was maintained in highlanders that were conceived, born, and raised in hypoxia (~ 12 kPa O2), suggesting that lung development was not impaired by post-natal hypoxia as it is in many other lowland mammals. However, developmental hypoxia increased lung volume and thus augmented total alveolar surface area from P14. Overall, our findings suggest that evolutionary adaptation and developmental plasticity lead to changes in lung morphology that should improve pulmonary O2 uptake in deer mice native to high altitude.Due to the continued high incidence and mortality rate worldwide, there is a need to develop new strategies for the quick, precise, and valuable recognition of presenting injury pattern in traumatized and poly-traumatized patients. Extracellular vesicles (EVs) have been shown to facilitate intercellular communication processes between cells in close proximity as well as distant cells in healthy and disease organisms. miRNAs and proteins transferred by EVs play biological roles in maintaining normal organ structure and function under physiological conditions. In pathological conditions, EVs change the miRNAs and protein cargo composition, mediating or suppressing the injury consequences. Therefore, incorporating EVs with their unique protein and miRNAs signature into the list of promising new biomarkers is a logical next step. In this review, we discuss the general characteristics and technical aspects of EVs isolation and characterization. We discuss results of recent in vitro, in vivo, and patients study describing the role of EVs in different inflammatory diseases and traumatic organ injuries. miRNAs and protein signature of EVs found in patients with acute organ injury are also debated.
Arthroscopy of the central and peripheral compartment is an obligatory part of hip arthroscopy to evaluate, confirm or find pathologies and their treatment.

Loose bodies, lesions of the labrum and ligamentum capitis femoris, cartilage damage, femoroacetabular impingement, synovial diseases, initial osteoarthritis, femoral head necrosis (ARCO stage1-2) and adhesions.

Local infections, bone tumors near the joint, extensive peri-articular ossification, severe arthrofibrosis with peri-articular involvement, advanced osteoarthritis, protrusio acetabuli, advanced femoral head necrosis (from ARCO stage3-4 extended), recent fracture of the acetabulum and extensive joint capsule tears.

Precise positioning of the patient on afracture table is essential to avoid complications. Central and peripheral compartment arthroscopy requires at least2, in some cases more than 3portals. Arthroscopy of the central compartment is carried out under traction by an anterolateral (AL) and anterior portal(A). Aposterolateral (PL)ossible or not performed, even after previous arthroscopy of the peripheral compartment with capsule release. Intraoperative or directly postoperative problems and complications were rare, e.g., damage to the skin/genitals due to contact pressure (0.7%), instrument breakage (0.5%), transient lesions of the pudendus nerve (<1.5%).
From 01/2010-12/2019, 2815 hip arthroscopies were performed; average patient age 43 (12-81) years. All procedures include a diagnostic arthroscopy of the hip. Two to 5 portals were used. Average operation time was 70 (18-48) min. In 26 cases (0.9%), arthroscopy of the central compartment at a high CE angle was not possible or not performed, even after previous arthroscopy of the peripheral compartment with capsule release.
