Spinal extradural arteriovenous fistulas (SEDAVFs) are a rare form of spinal arteriovenous fistulas, the etiology of which has not been completely elucidated. To our knowledge, this is the first reported case of SEDAVF that may have been caused by a spinal procedure. This report describes a 50-year-old female patient who presented with an SEDAVF at the L3/4 level that developed 3 years after a transforaminal epidural block due to disc extrusion, after which she underwent no other operation or trauma. From routine spine magnetic resonance imaging, disc sequestration was considered more likely than vascular malformation. However, on lumbar CT angiography (CTA) and three-dimensional volume rendering images (3D-VRI), the lesion showed good association with arteries of the aortic branches, allowing us to confirm the exact diagnosis of the lesion as SEDAVF. A limitation of 3D-VRI reconstruction is the difficulty in separate visualization of the vertebral body and blood vessels. On follow-up CTA, 3D dual-energy computed tomography (DECT) depicted smaller vascular structures and showed their anatomical relationships to the bone. While spinal angiography has been traditionally known as the gold standard for SEDAVF diagnosis, CTA with 3D-VRI, especially obtained by DECT, allows clinicians to make an accurate diagnosis and treatment plan that are difficult to judge by routine MRI.Objective To investigate the muscle activity patterns of the glenohumeral joint during internal rotation both with the arm at 0° and 90° of abduction using 2-deoxy-2-[18F] fluoro-D-glucose (FDG) positron emission tomography (PET) and magnetic resonance imaging (MRI). Materials and methods Six healthy male volunteers underwent PET examination after performing active glenohumeral internal rotation exercise using an elastic band both with the arm at 0° and 90° of abduction. As a control, PET scan under resting condition was also performed. The exercise was performed before and after 18 fluorodeoxyglucose injection. Each PET image was fused to the corresponding MRI to identify each muscle. The standardized uptake value (SUV) of each muscle was compared between the two arm positions. Results With the arm at 0° of abduction, the SUV increased significantly after exercise both in the middle and inferior 1/3 of the subscapularis, which were significantly higher than that of the superior 1/3 of the subscapularis (P less then 0.05). The SUV of the inferior 1/3 of the subscapularis was significantly higher at 90° of abduction than at 0° of abduction and was significantly higher than that of the superior 1/3 at 90° of abduction (P less then 0.01). The SUV after exercise in the inferior infraspinatus and teres minor increased. Conclusions The middle and inferior parts of the subscapularis are the main shoulder internal rotators in 0° of abduction, whereas the inferior part of the subscapularis is the main internal rotator in 90° of abduction.We present a rare case of a 4-year-old girl suffering from a sclerotic lesion on the forehead as well as uveitis and epileptic seizures. The patient was diagnosed with linear scleroderma "en coup de sabre" (LSECDS). Faced with no gold standard for treatment of LSECDS with severe extracutaneous manifestations, the case was intensively discussed within an interdisciplinary team setting and successfully treated.Basal cell carcinoma is the most common type of cancer in Central Europe and has a high medical relevance. Due to its high tendency of recurrence, an important parameter in the planning of therapy is the risk of recurrence. After clinical and histological diagnosis, the majority of tumors are treated surgically, although radiation and topical procedures are also possible therapeutic alternatives in certain constellations. Hedgehog inhibitors, a completely new class of substances, have recently been approved for rare metastatic and locally advanced diseases, thus significantly expanding the range of treatments. This article provides an overview of the current guideline-based diagnosis and therapy of basal cell carcinomas in Germany.Background Percutaneous access to the renal pelvis still remains the most difficult step before nephrolitholapaxy (PCNL). New imaging techniques, such as 3D imaging and various navigation instruments such as electromagnetic, sonographic, CT-controlled and marker-based/iPAD try to simplify this step and reduce complications. Objectives In this review, various new techniques for puncturing the renal collecting system are presented and their advantages and disadvantages are evaluated. Materials and methods A systematic literature search was carried out in MEDLINE, whereby only puncture techniques that have already been evaluated in clinical studies were included. Results Five different navigation methods for puncturing the renal pelvis before PCNL were found. Conclusion Intraoperative navigation can be useful when puncturing the collecting system. The combination of ultrasound and fluoroscopy currently remains the gold standard. However, there is still a need for further, primarily clinical, prospective studies to determine which new imaging technology and navigation systems will prevail and thus facilitate the access route to the kidney, especially in the case of special anatomical conditions.Chamber-specific and temporally regulated perinatal cardiac growth and maturation is critical for functional adaptation of the heart and may be altered significantly in response to perinatal stress, such as systemic hypoxia (hypoxemia), leading to significant pathology, even mortality.  https://www.selleckchem.com/products/elsubrutinib.html  Understanding transcriptome regulation of neonatal heart chambers in response to hypoxemia is necessary to develop chamber-specific therapies for infants with cyanotic congenital heart defects (CHDs). We sought to determine chamber-specific transcriptome programming during hypoxemic perinatal circulatory transition. We performed transcriptome-wide analysis on right ventricle (RV) and left ventricle (LV) of postnatal day 3 (P3) mouse hearts exposed to perinatal hypoxemia. Hypoxemia decreased baseline differences between RV and LV leading to significant attenuation of ventricular patterning (AVP), which involved several molecular pathways, including Wnt signaling suppression and cell cycle induction. Notably, robust changes in RV transcriptome in hypoxemic condition contributed significantly to the AVP.
