Abstract
Felix Mendelssohn Bartholdy (1805-1847) is widely regarded as one of the musical geniuses of the Romantic period. A prodigy akin to Mozart, Mendelssohn composed piano works, symphonies, and concertos at an early age but died young, at 38. His death has been attributed to neurological disease, but the mystery of his diagnosis is amplified by the fact that his sisters died under similar circumstances, including the renowned composer, Fanny Mendelssohn Hensel. Mendelssohn died after years of suffering from headaches, earaches, and mood disturbances. In the final year of his life, his acute decline was marked by stepwise, progressive neurologic deficits: gait disturbance, loss of sensation in the hands, partial paralysis, and, finally, loss of consciousness. The similar pattern of disease within his family suggests an underlying genetic link, though this may be multifactorial in nature. We present a thorough, posthumous differential diagnosis for Mendelssohn's illness, given his medical history, the familial pattern, and hints from within his music. Possible diagnoses include ruptured cerebral aneurysm with resultant subarachnoid hemorrhage, familial cerebral cavernous malformation, and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Continued research into Mendelssohn's life may yield more information about his illness, death, and possibly true diagnosis.

Abstract
Heritable thoracic aortic disease puts patients at risk for aortic aneurysms, rupture, and dissections. The diagnosis and management of this heterogenous patient population continues to evolve. Last year, the American Heart Association/American College of Cardiology Joint Committee published diagnosis and management guidelines for aortic disease, which included those with genetic aortopathies. Additionally, evolving research studying the implications of underlying genetic aberrations with new genetic testing continues to become available. In this review, we evaluate the current literature surrounding the diagnosis and management of heritable thoracic aortic disease, as well as novel therapeutic approaches and future directions of research.

Abstract
BACKGROUND Vertebral artery dissection (VAD) is an infrequent source of subarachnoid hemorrhage (SAH), with a high mortality rate, primarily due to the risk of rebleeding both before and after medical intervention. This paper provides a comprehensive analysis of the anatomy, pathophysiology, clinical presentation, treatment strategies, and outcomes of intracranial vertebral artery dissections that result in subarachnoid hemorrhage. METHODS Comprehensive five-year literature review (2018-2022) and a retrospective analysis of patient records from our institution between 2016 and 2022. We included studies with a minimum of 5 patients. RESULTS The study incorporated ten series from the literature and 22 cases from CHUM. Key anatomical factors increasing the risk of VAD include the vertebral artery's origin from the aortic arch, asymmetry of the vertebral artery, and its tortuosity. Patients may display specific collagen and genetic abnormalities. The occurrence of VAD appears to be more prevalent in men. Those with a ruptured intracranial VAD typically show prodromal symptoms and present with severe SAH. Rebleeding within the first 24 h is frequent. While standard imaging methods are usually adequate for VAD diagnosis, they may not provide detailed information about the perforator anatomy. Treatment approaches include both deconstructive and reconstructive methods. CONCLUSION Ruptured VAD is a critical, life-threatening condition. Many patients have a poor neurological status at presentation, and rebleeding prior to treatment is a significant concern. Deconstructive techniques are most effective in preventing rebleeding, whereas the efficacy of reconstructive techniques needs more investigation.

Abstract
BACKGROUND Ehlers-Danlos syndrome Type IV (aka Vascular Ehlers Danlos, or vEDS) is a dominantly inherited mutation in the Collagen 3A1 gene (COL3A1). The disease is characterized by tissue friability and age-related susceptibility to arterial aneurysm, dissection and rupture as well as uterine and bowl tears. These clinical manifestations result in major surgical intervention and decreased life expectancy. Understanding how mutations in COL3A1 impact the structure and function of the extracellular matrix (ECM) is important to managing the disease and finding treatments. RESULTS Skin fibroblasts from vEDS subjects heterozygous for the p.G588S pathogenic variant in the COL3A1 gene and a normal individual were cultured and studied. Proteomics analysis identified dozens of upregulated proteins related to extracellular matrix dysregulation that is characteristic of fibrosis. Gene expression libraries from cultured primary fibroblasts were screened for messenger RNA (mRNA) markers of ECM degradation. The proteomics and targeted gene expression array results were largely consistent with dysregulation of the extracellular matrix in vEDS. The data show upregulation of multiple Collagen proteins and genes, other ECM components, and enzymes related to ECM processing and turn-over. vEDS fibroblasts expressed significantly more cross linked C-Telopeptide of Collagen III (CTXIII) than normal fibroblasts, indicative of Collagen III degradation and turn-over. Further, the expression and activity of Lysyl Oxidase (LOX), an enzyme that initiates covalent cross-linking of soluble collagen and elastin into protease resistant fibers, is elevated in vEDS fibroblasts compared to normal fibroblasts. CONCLUSION Together, these findings suggest dysregulated ECM deposition and processing, reminiscent of a state of fibrosis. Therapeutics that target the dysregulated ECM proteins or help replace damaged tissue may improve clinical outcomes.

Abstract
Ehlers-Danlos syndrome (EDS) type IV is a hereditary autosomal dominant disease associated with skin and vascular fragility, hyperextensibility and joint hypermobility. Spontaneous arterial rupture is one of its higher-risk features.The authors describe a case of a woman with EDS type IV who presented with a spontaneous breast haematoma associated with a pseudoaneurysm of a branch of the left internal mammary artery. The patient underwent a minimally invasive endovascular approach that was uneventful. However, 6 months later, she presented in the emergency room with a similar episode on the contralateral breast. There were no signs of active bleeding, and she stayed under surveillance. Nine months later, she was asymptomatic.Aneurysms of branches of the internal mammary artery are rare and prone to rupture. Early diagnosis and treatment are imperative, and this case demonstrates that an endovascular approach is a safe treatment option.

Abstract
Although the impact of age, gender, and obesity on the skin wound healing process has been extensively studied, the data related to gender differences in aspects of skin scarring are limited. The present study performed on abdominal human intact and scar skin focused on determining gender differences in extracellular matrix (ECM) composition, dermal white adipose tissue (dWAT) accumulation, and Foxn1 expression as a part of the skin response to injury. Scar skin of men showed highly increased levels of COLLAGEN 1A1, COLLAGEN 6A3, and ELASTIN mRNA expression, the accumulation of thick collagen I-positive fibers, and the accumulation of α-SMA-positive cells in comparison to the scar skin of women. However, post-injured skin of women displayed an increase (in comparison to post-injured men's skin) in collagen III accumulation in the scar area. On the contrary, women's skin samples showed a tendency towards higher levels of adipogenic-related genes (PPARγ, FABP4, LEPTIN) than men, regardless of intact or scar skin. Intact skin of women showed six times higher levels of LEPTIN mRNA expression in comparison to men intact (p < 0.05), men post-injured (p < 0.05), or women post-injured scar (p < 0.05) skin. Higher levels of FOXN1 mRNA and protein were also detected in women than in men's skin. In conclusion, the present data confirm and extend (dWAT layer) the data related to the presence of differences between men and women in the skin, particularly in scar tissues, which may contribute to the more effective and gender-tailored improvement of skin care interventions.

Abstract
Aortic and visceral aneurysms affect large arterial vessels, including the thoracic and abdominal aorta, as well as visceral arterial branches, such as the splenic, hepatic, and mesenteric arteries, respectively. Although these clinical entities have not been equally researched, it seems that they might share certain common pathophysiological changes and molecular mechanisms. The yet limited published data, with regard to newly designed, novel therapies, could serve as a nidus for the evaluation and potential implementation of such treatments in large artery aneurysms. In both animal models and clinical trials, various novel treatments have been employed in an attempt to not only reduce the complications of the already implemented modalities, through manufacturing of more durable materials, but also to regenerate or replace affected tissues themselves. Cellular populations like stem and differentiated vascular cell types, large diameter tissue-engineered vascular grafts (TEVGs), and various molecules and biological factors that might target aspects of the pathophysiological process, including cell-adhesion stabilizers, metalloproteinase inhibitors, and miRNAs, could potentially contribute significantly to the treatment of these types of aneurysms. In this narrative review, we sought to collect and present relevant evidence in the literature, in an effort to unveil promising biological therapies, possibly applicable to the treatment of aortic aneurysms, both thoracic and abdominal, as well as visceral aneurysms.

Abstract
BACKGROUND Ehlers-Danlos syndrome is an inherited connective-tissue disorder characterized by skin hyperextensibility, joint hypermobility, and tissue fragility. Intestinal perforation is one of the fatal manifestations of this syndrome, and its management is complicated. CASE PRESENTATION A 58-year-old woman with a familial history of Ehlers-Danlos syndrome visited the emergency department due to a sudden onset of lower abdominal pain. Plain abdominal computed tomography showed abdominal free air. We found a perforated descending colon and subsequently resected this lesion and performed ileostomy. Fifty-one days after this first operation, the patient had transverse colon perforation and thus underwent the Hartmann procedure as the second operation. In addition, she was diagnosed with small bowel perforation 53 days after the first operation and consequently underwent a third operation-partial resection of the jejunum with functional end-to-end anastomosis. Fifty-eight days after the first operation, she complained of acute abdominal pain. Plain abdominal computed tomography showed fluid collection near the jejunojejunal anastomosis. We detected dehiscence at the entry hole of the linear stapler during the operation and thus performed partial resection of the affected jejunum, followed by jejunostomy. The postoperative course of the fourth operation was uneventful. Genetic testing revealed a novel missense mutation (c.2095G>T, p.Gly699Cys) in the COL3A1 gene, which is presumed to be a pathogenic variant of vascular Ehlers-Danlos syndrome. CONCLUSION Vascular Ehlers-Danlos syndrome should be considered in the case of repeated intestinal perforation. The identified missense mutation in the COL3A1 gene (c.2095G>T, p.Gly699Cys) might be a novel pathogenic variation causing vascular Ehlers-Danlos syndrome. Careful postoperative screening and multidisciplinary management are required.

Abstract
Objectives Spontaneous cervical artery dissections (SCeAD) and coronary artery dissections (SCoAD) are major causes of neurovascular and cardiovascular morbidity in young adults. Although multiple aspects of their etiology are still unknown, most consensuses are focused on the presence of constitutional genetic aspects and environmental triggers. Since recent evidence of genetic contribution points to a possible overlap between these conditions, we aimed to describe current information on SCeAD and SCoAD genetics and their potential shared pathological aspects. Materials and methods A narrative review is presented. Publications in English and Spanish were queried using database search. The articles were evaluated by one team member in terms of inclusion criteria. After collecting, the articles were categorized based on scientific content. Results Given that patients with SCeAD and SCoAD rarely present connective tissue disorders, other genetic loci are probably responsible for the increased susceptibility in some individuals. The common variant rs9349379 at PHACTR1 gene is associated with predisposition to pathologies of the arterial wall, likely mediated by variations in Endothelin-1 (ET-1) levels. The risk of arterial dissection may be increased for those who carry the rs9349379(A) allele, associated with lower expression levels of ET-1; however, the local effect of this vasomotor imbalance remains unclear. Sex differences seen in SCeAD and SCoAD support a role for sex hormones that could modulate risk, tilting the delicate balance and forcing vasodilator actions to prevail over vasoconstriction due to a reduction in ET-1 expression. Conclusions New evidence points to a common gene variation that could explain dissection in both the cervical and coronary vasculatures. To further confirm the risk conferred by the rs9349379 variant, genome wide association studies are warranted, hopefully in larger and ethnically diverse populations.

Abstract
It is critical to accurately predict the rupture risk of an intracranial aneurysm (IA) for timely and appropriate treatment because the fatality rate after rupture is 50 % . Existing methods relying on morphological features (e.g., height-width ratio) measured manually by neuroradiologists are labor intensive and have limited use for risk assessment. Therefore, we propose an end-to-end deep-learning method, called TransIAR net, to automatically learn the morphological features from 3D computed tomography angiography (CTA) data and accurately predict the status of IA rupture. We devise a multiscale 3D convolutional neural network (CNN) to extract the structural patterns of the IA and its neighborhood with a dual branch of shared network structures. Moreover, we learn the spatial dependence within the IA neighborhood with a transformer encoder. Our experiments demonstrated that the features learned by TransIAR are more effective and robust than handcrafted features, resulting in a 10 % - 15 % improvement in the accuracy of rupture status prediction.

Abstract
OBJECTIVE To assess the complex management of arterial anomalies in Vascular Ehlers-Danlos Syndrome (vEDS). METHODS We report the case of a 34-year-old male, diagnosed with vEDS, who presented with acute intraperitoneal hemorrhage caused by the rupture of a splenic artery aneurysm, treated in emergency with coil embolization and splenectomy. Computed Tomography (CT) scan showed the concomitant presence of right renal artery (RRA) and common hepatic artery (CHA) aneurysms. RESULTS Both aneurysms were conservatively managed and the patient went through serial CT imaging. After 3 months, rapid regression of the vascular abnormalities led to complete disappearing of RRA and CHA aneurysms, confirmed at 24-month imaging follow-up. In the same time span, two pseudoaneurysms developed in other sites used for transarterial access, requiring two secondary interventions. The present case emphasizes the unpredictability of disease's evolution and arterial complications in vEDS. Conservative management of complex lesions such as visceral artery aneurysms, which in this case resulted to be the best strategy, avoided the risks associated with surgical intervention in such fragile tissues. The reported complications underline that operative indications should be carefully weighed in these patients.

Abstract
We have described a case of multiple surgeries for a ruptured popliteal artery in an 11-year-old female patient with vascular Ehlers-Danlos syndrome. She underwent emergency hematoma evacuation and ruptured popliteal artery interposition with the great saphenous vein graft, which was notably fragile during surgery and had ruptured on the seventh postoperative day. We performed another emergency hematoma evacuation and popliteal artery interposition with an expanded polytetrafluoroethylene vascular graft. Despite the early occlusion of the expanded polytetrafluoroethylene graft, she recovered with mild intermittent claudication in the left lower extremity and was discharged on postoperative day 20 after the first surgery.

Abstract
BACKGROUND Aortic aneurysm (AA) is a "silent killer" human disease with no effective treatment. Although the therapeutic potential of various pharmacological agents have been evaluated, there are no reports of β-arrestin-biased AT1R (angiotensin-II type-1 receptor) agonist (TRV027) used to prevent the progression of AA. METHODS We tested the hypothesis that TRV027 infusion in AngII (angiotensin II)-induced mouse model of AA prevents AA. High-fat-diet-fed ApoE (apolipoprotein E gene)-null mice were infused with AngII to induce AA and co-infused with TRV027 and a clinically used AT1R blocker Olmesartan to prevent AA. Aortas explanted from different ligand infusion groups were compared with assess different grades of AA or lack of AA. RESULTS AngII produced AA in ≈67% male mice with significant mortality associated with AA rupture. We observed ≈13% mortality due to aortic arch dissection without aneurysm in male mice. AngII-induced AA and mortality was prevented by co-infusion of TRV027 or Olmesartan, but through different mechanisms. In TRV027 co-infused mice aortic wall thickness, elastin content, new DNA, and protein synthesis were higher than untreated and Olmesartan co-infused mice. Co-infusion with both TRV027 and Olmesartan prevented endoplasmic reticulum stress, fibrosis, and vasomotor hyper responsiveness. CONCLUSIONS TRV027-engaged AT1R prevented AA and associated mortality by distinct molecular mechanisms compared with the AT1R blocker, Olmesartan. Developing novel β-arrestin-biased AT1R ligands may yield promising drugs to combat AA.

Abstract
Cerebral stroke remains the leading cause of death and disability worldwide as well as in Ukraine. After a cerebral stroke, there is an increased risk of a new cerebral stroke (9‒15 % within 1 year), and about a quarter of all cerebral stroke are recurrent. Up to 80 % of recurrent cerebral stroke can be avoided through lifestyle modifications (healthy diet, sufficient amount of physical activity, normalization of body weight, cessation of smoking and alcohol abuse) and control of chronic diseases such as hypertension, diabetes, hyperlipidemia and atrial fibrillation. The key to effective secondary prevention is determining the etiology of cerebral stroke, which requires a primary examination in all cases and a number of additional tests as needed. The most common causes of ischemic cerebral stroke are cardiogenic embolism, atherosclerosis of the large cerebral arteries (macroangiopathy), and brain small vessels disease (microangiopathy), but approximately 1/3 of cerebral stroke have other, rear, determined cause or the cause remains unknown despite the appropriate workup (cryptogenic cerebral stroke). In the review, we discuss modern approaches to ischemic cerebral stroke classification and determination of their etiology, from the most prevalent to the rarest causes. A careful search for the cause of cerebral stroke is particularly important in young patients (aged 18 to 50 years) with a high life expectancy. We have reviewed in detail the possibilities of screening for subclinical atrial fibrillation by long-term cardiac monitoring with implantable devices and the diagnosis of monogenetic causes of cerebral stroke, with a particular focus on Fabry disease, for which there is an effective treatment.

Abstract
Vascular Ehlers-Danlos syndrome (vEDS) is a rare autosomal dominant genetic disorder. It is the most fatal among all types of EDS. In addition to typical EDS characteristics, vEDS patients are at risk of blood vessel rupture due to possession of pathogenic variants of the COL3A1 gene, which encodes type III collagen. Type III collagen is a major component of humans' vascular walls. The management of this disease is possible; however, there is no cure as of present. Recently, discoveries with potential impact on the management of vEDS have been elucidated. Mice with vEDS traits treated with a beta-blocker celiprolol showed significant improvements in their thoracic aorta biomechanical strength. Moreover, it has been demonstrated that the specifically designed small interference RNAs (siRNA) can effectively silence the pathogenic variant allele. To enhance the normal allele expression, an intracellularly expressed lysyl oxidase is shown to regulate the transcription rate of the COL3A1 promoter. Similarly, an embryonic homeobox transcription factor Nanog upregulates the wild-type COL3A1 expression through activation of the transforming growth factor-beta pathway, which increases type III collagen synthesis. Despite numerous advancements, more studies are to be performed to incorporate these discoveries into clinical settings, and eventually, more personalized treatments can be created.

Abstract
The subclavian artery is an important structure that may be overlooked at CT of the chest and neck, in part because of its anatomic location at the periphery of the field of view but also because the clinical indication for CT examinations infrequently directs attention specifically to evaluation of the subclavian artery. As with all arteries, the subclavian artery has the potential to be involved in a variety of abnormalities, including pseudoaneurysms, dissections, stenosis or thrombosis, and vasculopathies. In addition, the subclavian artery can be secondarily involved as a collateral pathway because of an abnormality elsewhere. The subclavian artery may also be involved in surgical procedures to supply blood to other sites in the body or as an arterial access site. In these cases, recognizing the postsurgical appearance of the subclavian artery has become increasingly complex because of the use of the artery in an increasing number of procedures. Recognizing expected postoperative changes remains important to avoid mistaking them for abnormalities. The authors describe the imaging appearance of the normal anatomy of the subclavian artery and its anatomic variants, related abnormalities, and important postsurgical considerations. ©RSNA, 2022.

Abstract
Isolated small bowel perforation is low in the differential diagnosis of abdominal pain in the young, relatively healthy patient. It is, however, a rare manifestation of type IV (vascular) Ehlers-Danlos syndrome (EDS). In addition, there is no general consensus on the management of GI manifestations in patients with type IV EDS. We present the case of a 31-year-old male with history of type IV EDS, presenting with acute onset abdominal pain. Imaging was notable for intra-abdominal free air and thickened loops of small bowel in the pelvis. The patient underwent exploratory laparotomy with resection of the small bowel perforation with enteroenteric anastomosis. In our literature review, we evaluated gastrointestinal manifestations observed in patients with type IV EDS, management recommendations and potential complications to be mindful of in this population.

Abstract
Impaired wound healing is one of the unsolved problems of modern medicine, affecting patients’ quality of life and causing serious economic losses. Impaired wound healing can manifest itself in the form of chronic skin wounds or hypertrophic scars. Research on the biology and physiology of skin wound healing disorders is actively continuing, but, unfortunately, a single understanding has not been developed. The attention of clinicians to the biological and physiological aspects of wound healing in the skin is necessary for the search for new and effective methods of prevention and treatment of its consequences. In addition, it is important to update knowledge about genetic and non-genetic factors predisposing to impaired wound healing in order to identify risk levels and develop personalized strategies for managing such patients. Wound healing is a very complex process involving several overlapping stages and involving many factors. This thematic review focuses on the extracellular matrix of the skin, in particular its role in wound healing. The authors analyzed the results of fundamental research in recent years, finding promising potential for their transition into real clinical practice.

Abstract
Strokes are the main cause of death and long-term disability worldwide. A stroke is a heterogeneous multi-factorial condition, caused by a combination of environmental and genetic factors. Monogenic disorders account for about 1% to 5% of all stroke cases. The most common single-gene diseases connected with strokes are cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) Fabry disease, mitochondrial myopathy, encephalopathy, lactacidosis, and stroke (MELAS) and a lot of single-gene diseases associated particularly with cerebral small-vessel disease, such as COL4A1 syndrome, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL), and Hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS). In this article the clinical phenotype for the most important single-gene disorders associated with strokes are presented. The monogenic causes of a stroke are rare, but early diagnosis is important in order to provide appropriate therapy when available.

Abstract
Vascular Ehlers-Danlos syndrome is caused by mutations in the COL3A1 (collagen type III alpha-1) gene, resulting in loss of integrity of arteries and hollow organs. Patients are predisposed to dissection, aneurysm, and organ rupture. The median life expectancy is ∼51 years. We have described a unique presentation of spontaneous compartment syndrome, likely secondary to ischemia reperfusion injury, in a 32-year-old man with vascular Ehlers-Danlos syndrome. The compartment syndrome was treated with four-compartment fasciotomy, and subsequent evaluation demonstrated a pseudoaneurysm of the tibioperoneal trunk. Endovascular intervention and stent graft deployment guided by intravascular ultrasound successfully excluded the pseudoaneurysm with three vessel run off preserved.

Abstract
Thoracic aortic aneurysm (TAA) formation is a multifactorial process that results in diverse clinical manifestations and drug responses. Identifying the critical factors and their functions in Marfan syndrome (MFS) pathogenesis is important for exploring personalized medicine for MFS. Methylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), and methionine synthase reductase (MTRR) polymorphisms have been correlated with TAA severity in MFS patients. However, the detailed relationship between the folate-methionine cycle and MFS pathogenesis remains unclear. Fbn1C1039G/+ mice were reported to be a disease model of MFS. To study the role of the folate-methionine cycle in MFS, Fbn1C1039G/+ mice were treated orally with methionine or vitamin B mixture (VITB), including vitamins B6, B9, and B12, for 20 weeks. VITB reduced the heart rate and circumference of the ascending aorta in Fbn1C1039G/+ mice. Our data showed that the Mtr and Smad4 genes were suppressed in Fbn1C1039G/+ mice, while VITB treatment restored the expression of these genes to normal levels. Additionally, VITB restored canonical transforming-growth factor β (TGF-β) signaling and promoted Loxl1-mediated collagen maturation in aortic media. This study provides a potential method to attenuate the pathogenesis of MFS that may have a synergistic effect with drug treatments for MFS patients.

[PMID: 34696817 PMCID: PMC8547026 DOI: 10.1186/s13256-021-03108-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 09/10/2021] [Indexed: 11/23/2022] Open
Abstract
Background Ehlers–Danlos syndrome is a clinically and genetically heterogeneous group of heritable connective tissue disorders caused by a defect in collagen synthesis and structure. The vascular subtype (Ehlers–Danlos syndrome IV) is reported to be associated with a higher incidence of gastrointestinal perforations. The most reported site of perforation is the colon, followed by the small bowel. Perforation of the stomach is very rare, and there are no reported cases to date of classic types I and II. Case presentation We present the case of a 14-year-old Saudi girl who visited our emergency department with abdominal pain and vomiting. Initially, she was diagnosed with gastroenteritis and discharged once her condition stabilized. After 48 hours, she developed severe abdominal pain with recurrent vomiting and peritonitis evident on clinical examination. Initial abdominal x-ray failed to show any free air; however, enhanced computed tomography revealed free air and contrast extravasation in the proximal gut. During exploratory laparotomy, a large perforation was found on the anterior wall of the stomach due to the underlying ischemia. The posterior wall had ischemic mucosa with an intact healthy serosa. A free-hand partial gastrectomy was performed to resect all ischemic parts of the stomach. Detailed examinations and laboratory workup were carried out after the surgery to figure out the possible underlying cause. The clinical findings during the physical examination supported marfanoid features. Marfan’s syndrome and related disorders sequencing panel was requested, and Deoxyribonucleic acid (DNA) samples were sent. Given results were supporting the diagnosis of classical Ehlers–Danlos syndrome, the patient was labeled as a case of Ehlers–Danlos syndrome. During the postoperative period, she developed a wound infection that was managed successfully with vacuum-assisted closure dressing. She recovered well without gastrointestinal sequelae in the 4 years of follow-up. Conclusions Heritable systemic connective tissue diseases must be given serious consideration in young patients with unusual spontaneous perforation. Such patients might develop life-threatening conditions that require immediate intervention. Hence, correct and timely diagnosis is important to prepare for the anticipated complications.

Abstract
Background. This study deals with a rare (orphan) monogenic connective tissue disorder - Ehlers-Danlos syndrome kyphoscoliotic type 2 (EDSKS2). Kyphoscoliotic type 2 Ehlers-Danlos syndrome is an autosomal recessive disorder caused by mutations in the FKBP14 gene (7p14.3), which encodes the FKBP22 protein. According to the 2017 classification, this type is in group seven - collagen spatial structure and cross-linking defects. We present results of clinical examination and molecular genetic analysis for five patients with age varying from two to fifteen years. Methods. Five patients were examined using clinical and laboratory methods. DNA samples used for the analysis were extracted from whole blood samples using a Wizard® Genomic DNA Purification Kit (Promega, USA) according to the manufacturer's protocol. Results. The major clinical findings were kyphoscoliosis, early motor development delay, muscular weakness, hypotonia and hearing loss. Molecular genetic analysis detected a homozygous c.362dupC duplication in exon 3 of the FKBP14 gene in all five patients. This mutation is common in various countries. Differential diagnostics were carried out to exclude other Ehlers-Danlos syndrome types and myopathies. Conclusions. Literature analysis and examination of five EDSKS2 patients demonstrated the involvement of major organs and systems, such as joints, spine, muscles, cardiovascular system, respiratory system, hearing, and vision, into the pathological process. Kidney mobility increases and nephroptosis seems to be secondary caused by muscular weakness. During molecular genetic analysis, to verify EDSKS2 it is recommended to initially search for the c.362dupC duplication, which appears to be common in European countries, including Russia.

Abstract
A novel COL3A1 variant was identified in a Japanese case of Ehlers-Danlos syndrome type IV (EDS-IV) with a characteristic "Madonna" face, fragile uterus, and easy bruising in addition to a history of cavernous sinus fistula. We confirmed variable diameters of collagen fibrils in the dermis and decrease in type 3 collagen production from cultured fibroblasts. Genomic DNA sequencing of the COL3A1 region and COL3A1 cDNA sequence expressing in cultured fibroblasts identified that a nucleotide variation at c.951+2T>G on intron 14 leads to skipping of exon 14 in COL3A1 cDNA. The novel variation in the splice site of COL3A1 region g.IVS14+2T>G was not listed in the EDS-IV pathogenic genetic databases including Human Gene Mutation Database, ClinVar, and Leiden Open Variation Database. Using the whole genome sequence database of 8380 Japanese individuals reported by the Tohoku Medical Megabank Organization (ToMMo) cohort study, we also confirmed that COL3A1 g.IVS14+2T>G was not a common single nucleotide variation in the Japanese population, although 13 EDS-related COL3A1 variants were identified in the ToMMo database of 8380 Japanese individuals. These results demonstrated that our case of EDS-IV was a result of the novel variation of COL3A1 g.IVS14+2T>G. These statistical genetics approaches with the combination of the ToMMo database of 8380 Japanese individuals and pathogenic genetic databases are a useful method to confirm the uniqueness of novel variation in Japanese.

Abstract
INTRODUCTION Ehlers-Danlos syndrome is a well classified connective tissue disorder recognized by its features of hyperextensibility of joints and hyperelasticity of the skin. However, the rare vascular type (Ehlers-Danlos type IV) is more difficult to identify in the absence, rarity, or subtlety of the classical physical features. Patients presenting to the emergency department (ED) with acute complications of vascular Ehlers-Danlos syndrome may be critically ill, requiring accurate diagnosis and tailored management. CASE REPORT This report details a case of spontaneous innominate artery pseudoaneurysm rupture in a pediatric patient with previously undiagnosed Ehlers-Danlos syndrome. Initial ED evaluation was followed by urgent operative intervention and subsequent genetic testing to confirm final diagnosis. CONCLUSION Due to its high morbidity and mortality, vascular type Ehlers-Danlos syndrome should be considered in the differential for otherwise unexplained spontaneous vascular injury.

Abstract
Ehlers-Danlos syndrome (EDS) is an uncommon heterogenous autosomal dominant multisystemic connective tissue disorder, which may potentially present with life-threatening emergencies. The prevalence of EDS of all subtypes is from 1 in 10 000 to 1 in 20 000. Pregnancy in women with type IV EDS poses significant challenges, necessitating the care of multidisciplinary team. Potential complications of type IV EDS include arterial dissection, arterial aneurysm, visceral rupture, excessive bleeding, tissue fragility and delayed wound healing. We present an interesting case of a pregnant woman with type IV EDS who had previous cerebrovascular complications and had a successful delivery in our tertiary centre following a collaborative approach to her care.

Abstract
BACKGROUND Rare diseases (RDs) affect less than 5/10,000 people in Europe and fewer than 200,000 individuals in the United States. In rheumatology, RDs are heterogeneous and lack systemic classification. Clinical courses involve a variety of diverse symptoms, and patients may be misdiagnosed and not receive appropriate treatment. The objective of this study was to identify and classify some of the most important RDs in rheumatology. We also attempted to determine their combined prevalence to more precisely define this area of rheumatology and increase awareness of RDs in healthcare systems. We conducted a comprehensive literature search and analyzed each disease for the specified criteria, such as clinical symptoms, treatment regimens, prognoses, and point prevalences. If no epidemiological data were available, we estimated the prevalence as 1/1,000,000. The total point prevalence for all RDs in rheumatology was estimated as the sum of the individually determined prevalences. RESULTS A total of 76 syndromes and diseases were identified, including vasculitis/vasculopathy (n = 15), arthritis/arthropathy (n = 11), autoinflammatory syndromes (n = 11), myositis (n = 9), bone disorders (n = 11), connective tissue diseases (n = 8), overgrowth syndromes (n = 3), and others (n = 8). Out of the 76 diseases, 61 (80%) are classified as chronic, with a remitting-relapsing course in 27 cases (35%) upon adequate treatment. Another 34 (45%) diseases were predominantly progressive and difficult to control. Corticosteroids are a therapeutic option in 49 (64%) syndromes. Mortality is variable and could not be determined precisely. Epidemiological studies and prevalence data were available for 33 syndromes and diseases. For an additional eight diseases, only incidence data were accessible. The summed prevalence of all RDs was 28.8/10,000. CONCLUSIONS RDs in rheumatology are frequently chronic, progressive, and present variable symptoms. Treatment options are often restricted to corticosteroids, presumably because of the scarcity of randomized controlled trials. The estimated combined prevalence is significant and almost double that of ankylosing spondylitis (18/10,000). Thus, healthcare systems should assign RDs similar importance as any other common disease in rheumatology.

Abstract
ABSTRACT Vascular Ehlers-Danlos syndrome (EDSv) can present with life-threatening surgical complications. The article describes the case of a patient with EDSv who developed total abdominal wound dehiscence and multiple enterocutaneous fistulas. Treatment with IV allogeneic mesenchymal stromal cells (MSCs) and high-dose vitamin C was trialed with success. Near-complete wound healing of the abdominal dehiscence with a 94% reduction in the size of the wound bed occurred. Maturation of the enterocutaneous fistulas also ensued.There is no current consensus on the management of large cutaneous wounds in EDSv. This article discusses the pathophysiology of wound healing with regard to nutrition requirements and growth factors with special reference to collagen deficits in EDSv. A potential therapy with IV vitamin C supplementation and MSCs is proposed following the patient's positive outcome. Medium-dose MSCs and high-dose IV vitamin C may offer significant benefits to complex and problematic wounds.

Abstract
BACKGROUND The Ehlers-Danlos syndrome (EDS) is a group of connective tissue disorders characterized by fragile blood vessels and an increased tendency for bleeding and scarring. Here, we report the outcome of a pars plana vitrectomy for the treatment of rhegmatogenous retinal detachment in a patient with EDS type IV (vascular type). CASE PRESENTATION A 40-year-old Slovenian man with high myopia, unilateral bullous retinal detachment, and vitreous hemorrhage was referred for surgery. The patient had a history of colon perforation, muscle and arterial rupture in both lower limbs, and recurrent shoulder joint luxations. Genetic testing revealed a pathogenic mutation in the COL3A1 gene. The patient underwent a 25-gauge three-port pars plana vitrectomy. The tendency for bleeding during surgery was prevented by endodiathermy applied to the edges of the retinal breaks. Endolaser photocoagulation was performed under air. The surgical procedure was completed with the injection of gas tamponade, followed by the patient remaining for a few days in a face-down position. Mild postoperative vitreous hemorrhage was resorbed in first week after the surgery. Postoperative extensive pigment dispersion on the posterior lens face persisted for several weeks. After the gas tamponade had resorbed, the retina was flat and remained attached during the follow-up period. Eight months after the surgery, visual acuity continued to improve from a preoperative 6/38 to 6/6.6 (Snellen chart) at the last checkup. CONCLUSION A small-gauge pars plana vitrectomy with gas tamponade and laser photocoagulation under air may successfully achieve reattachment of the retina in patients with high myopia with EDS type IV and restore visual acuity.

Abstract
While prompt diagnosis of vasculitis is important, recognition of vasculitis mimics is equally essential. As in the case of vasculitis, an approach to mimics based on the anatomic size of vessels can be useful. Infections can mimic vasculitis of any vessel size, including the formation of aneurysms and induction of ANCAs. Genetic disorders and vasculopathies are important considerations in large and medium vessel vasculitis. Cholesterol emboli, thrombotic conditions and calciphylaxis typically affect the medium and small vessels and, like vasculitis, can cause cutaneous, renal and CNS manifestations. Reversible cerebral vasoconstriction syndrome is important to distinguish from primary angiitis of the CNS. As an incorrect diagnosis of vasculitis can result in harmful consequences, it is imperative that the evaluation of suspected vasculitis includes consideration of mimics. We discuss the above mimics and outline a systematic and practical approach for differentiating vasculitis from its mimics.

Abstract
Background Ehlers–Danlos syndrome (EDS) is an inherited disorder that causes connective tissue fragility. The vascular type of EDS (vEDS) caused by defective collagen type III production accounts for 5%–10% of all EDS cases. Patients can develop gastrointestinal or arterial ruptures, which cause poor prognosis. We report a case of a patient who experienced colonic rupture, which was immediately followed by arterial rupture. Case presentation A 40-year-old man who had been genetically diagnosed with vEDS 6 years previously was admitted to our hospital with ischemic colitis. After 3 days of conservative treatment, his abdominal pain worsened, and computed tomography (CT) revealed free air in the abdominal cavity. Pan-peritonitis due to perforation of the sigmoid colon was diagnosed. Intraperitoneal lavage and drainage and Hartmann’s operation were urgently performed. Because the patient had confirmed vEDS, we performed the surgery in a protective manner. The postoperative course was initially good, and he was transferred to the general ward 3 days after surgery. However, 5 days after surgery, massive intra-abdominal hemorrhage suddenly occurred, and contrast-enhanced CT showed an aneurysm in the common hepatic artery that had ruptured; this aneurysm was not present before surgery and was far from the surgical field. Although we considered an emergency operation, the patient suddenly experienced cardiac arrest and was unresponsive to resuscitation. Conclusions In cases of vEDS, vascular rupture can occur immediately after surgery for intestinal rupture. We recommend paying special attention to vascular complications in patients in their forties, as such complications are the most common causes of death.

Abstract
BACKGROUND AND PURPOSE Vascular Ehlers-Danlos syndrome is a rare inherited connective tissue disorder because of pathogenic variants in the COL3A1 gene. Arterial complications can affect all anatomic areas and about 25% involve supra-aortic trunks (SATs) but no systematic assessment of cervical artery lesions has been made. The primary objective was to determine an accurate prevalence of spontaneous SAT lesions in a large series of patients with vascular Ehlers-Danlos syndrome at diagnosis and during follow-up. Secondary objectives were to study their neurological consequences (transient ischemic attack or stroke) and the possible relationships with sex, genotype, ascertainment status. METHODS A retrospective review of a monocentric cohort of patients with molecularly proven vascular Ehlers-Danlos syndrome followed in a tertiary referral center from 2000 to 2017. RESULTS One hundred forty-four patients were analyzed, 56.9% (n=82) had SAT lesions: 64.6% females, 74.4% index-case patients. Most lesions were identified in early arterial assessment (48% at first work-up, mean age of 35.7±13.0 years). Cumulative incidence of a first identification of a SAT lesion was 41.7% at 40 years old. On the complete period of survey, 183 SAT lesions (with 132 dissections and 33 aneurysms) were identified, mainly in internal carotid arteries (56.3%) and vertebral arteries (28.9%), more rarely in patients with COL3A1 null mutations (P=0.008). Transient ischemic attack or stroke were reported in n=16 (19.5%) of the 82 patients with SAT lesions without relation with age, sex, treatment, or hypertension. CONCLUSIONS Cervical artery lesions are frequent and mostly asymptomatic in patients with vascular Ehlers-Danlos syndrome. Local dissections and aneurysms are the most frequent type of lesions, but transient ischemic attack or stroke seem rare.

Abstract
Ehlers-Danlos syndrome type IV (EDS-IV), the vascular type, is a rare genetic disorder affects the large and medium size arteries resulting in dissections, often with aneurysmal degeneration, intramural hematomas and pseudoaneurysms. Embolization or ligation is standard management for aneurysm formation. We present a case of an EDS-IV patient with a posterior tibial artery dissection with associated aneurysm successfully treated with Flow Diversion stent (FDS) preserving vessel patency and excluding the aneurysm. FDS technology allows for low profile, micro-catheter deliverable treatment options to exclude aneurysms in EDS-IV patients that are may be prone to spasm and dissection using more conventional stent graft technology.

Abstract
Background Ehlers–Danlos syndrome (EDS) type IV is a rare subtype of EDS, but has important surgical implications. Case presentation Here, we present a case of a spontaneous sigmoid perforation in a 14-year-old boy. He was initially treated with laparotomy, oversew of the sigmoid perforation and a diverting ileostomy. He developed a complete wound dehiscence and enteroatmospheric fistulae. These were managed with a combination of negative pressure wound therapy and Eakin (TG Eakin™) pouch changes. We discuss the clinical features and presentation of EDS type IV, the surgical implications of managing patients with the condition, and the challenges in management of enteroatmospheric fistulae in children. Conclusions Ehlers–Danlos syndrome type IV should be considered as a cause of any spontaneous colonic perforation in children.

Abstract
Aneurysmal subarachnoid hemorrhage (SAH) affects six to nine people per 100,000 per year, has a 35% mortality, and leaves many with lasting disabilities, often related to cognitive dysfunction. Clinical decision rules and more sensitive computed tomography (CT) have made the diagnosis of SAH easier, but physicians must maintain a high index of suspicion. The management of these patients is based on a limited number of randomized clinical trials (RCTs). Early repair of the ruptured aneurysm by endovascular coiling or neurosurgical clipping is essential, and coiling is superior to clipping in cases amenable to both treatments. Aneurysm repair prevents rebleeding, leaving the most important prognostic factors for outcome early brain injury from the hemorrhage, which is reflected in the neurologic condition of the patient, and delayed cerebral ischemia (DCI). Observational studies suggest outcomes are better when patients are managed in specialized neurologic intensive care units with inter- or multidisciplinary clinical groups. Medical management aims to minimize early brain injury, cerebral edema, hydrocephalus, increased intracranial pressure (ICP), and medical complications. Management then focuses on preventing, detecting, and treating DCI. Nimodipine is the only pharmacologic treatment that is approved for SAH in most countries, as no other intervention has demonstrated efficacy. In fact, much of SAH management is derived from studies in other patient populations. Therefore, further study of complications, including DCI and other medical complications, is needed to optimize outcomes for this fragile patient population.

Abstract
Ehlers-Danlos syndrome (EDS) is a group of connective tissue disorders that can result in a range of complications during pregnancy. Pregnant EDS patients generally have a favourable outcome, but those with vascular EDS are more likely to suffer from severe maternal complications. Early diagnosis of EDS and subtype characterization can aid in pre-pregnancy counselling, planning of antenatal care, risk assessment of obstetric and neonatal complications, and influence both obstetric and anaesthetic management of these patients. This piece aims to outline the obstetric implications of classical, hypermobile, and vascular EDS, and review the current literature regarding their optimal obstetric management.

Abstract
Genetically triggered thoracic aortic aneurysms (TAAs) are usually considered to exhibit minimal levels of inflammation. However, emerging data demonstrate that specific features of an inflammatory response can be observed in TAA, and that the extent of the inflammatory response can be correlated with the severity, in both mouse models and in human studies. Myeloperoxidase (MPO) is a key mediator of the inflammatory response, via production of specific oxidative species, e.g., the hypohalous acids. Specific tissue modifications, mediated by hypohalous acids, have been documented in multiple cardiovascular pathologies, including atherosclerosis associated with coronary artery disease, abdominal aortic, and cerebral aneurysms. Similarly, data are now emerging that show the capacity of MPO-derived oxidative species to regulate mechanisms important in TAA pathogenesis, including alterations in extracellular matrix homeostasis, activation of matrix metalloproteinases, induction of endothelial dysfunction and vascular smooth muscle cell phenotypic switching, and activation of ERK1/2 signaling. The weight of evidence supports a role for inflammation in exacerbating the severity of TAA progression, expanding our understanding of the pathogenesis of TAA, identifying potential biomarkers for early detection of TAA, monitoring severity and progression, and for defining potential novel therapeutic targets.

Celiprolol but not losartan improves the biomechanical integrity of the aorta in a mouse model of vascular Ehlers-Danlos syndrome. Cardiovasc Res 2020; 116:457-465.

Abstract
AIMS Antihypertensive drugs are included in the medical therapy of vascular Ehlers-Danlos syndrome (vEDS). The β-blocker celiprolol has been suggested to prevent arterial damage in vEDS, but the underlying mechanism remains unclear. It is also unknown whether the widely used angiotensin II receptor type 1 antagonist losartan has a therapeutic effect in vEDS. Here, we evaluated the impact of celiprolol and losartan on the biomechanical integrity of the vEDS thoracic aorta. METHODS AND RESULTS We established a new approach to measure the maximum tensile force at rupture of uniaxially stretched murine thoracic aortic rings. In a vEDS model, which we (re-)characterized here at molecular level, heterozygous mice showed a significant reduction in the rupture force compared to wild-type mice, reflecting the increased mortality due to aortic rupture. For the assessment of treatment effects, heterozygous mice at 4 weeks of age underwent a 4-week treatment with celiprolol, losartan, and, as a proof-of-concept drug, the matrix metalloproteinase inhibitor doxycycline. Compared to age- and sex-matched untreated heterozygous mice, treatment with doxycycline or celiprolol resulted in a significant increase of rupture force, whereas no significant change was detected upon losartan treatment. CONCLUSIONS In a vEDS model, celiprolol or doxycycline, but not losartan, can improve the biomechanical integrity of the aortic wall, thereby potentially reducing the risk of dissection and rupture. As doxycycline is a broad-spectrum antibiotic with considerable side effects, celiprolol may be more suitable for a long-term therapy and thus rather indicated for the medication of patients with vEDS.

Abstract
OBJECTIVE To assess whether connective tissue disorder is evident in patients with spontaneous cervical artery dissection and therefore identify patients at risk of recurrence using a cutting-edge quantitative proteomics approach. METHODS In the ReSect study, all patients with spontaneous cervical artery dissection treated at the Innsbruck University Hospital since 1996 were invited to attend a standardized clinical follow-up examination. Protein abundance in skin punch biopsies (n = 50) was evaluated by a cutting-edge quantitative proteomics approach (liquid chromatography-mass spectrometry) that has hitherto not been applied to such patients. RESULTS Patients with 1-time single-vessel (n = 19) or multiple-vessel (n = 13) dissections did not differ between each other or compared to healthy controls (n = 12) in protein composition. Patients with recurrent spontaneous cervical artery dissection (n = 6), however, showed significantly different expression of 25 proteins compared to the other groups combined. Literature review and Gene Ontology term annotation check revealed that 13 of the differently expressed proteins play a major role in the structural integrity of connective tissue or are linked to connective tissue disorders. These proteins showed clustering to a collagen/elastin cluster and one consisting of desmosome related proteins. CONCLUSION This study unravels an extracellular matrix protein signature of recurrent spontaneous cervical artery dissection. In the long run and after large-scale validation, our findings may well assist in identifying patients at risk of recurrent spontaneous cervical artery dissection and thus guide therapy.

Abstract
Aortic aneurysms were the primary cause of nearly 10,000 deaths in 2014 according to data from the Centers for Disease Control and may involve segments of the thoracic or abdominal aorta. Thoracic aortic aneurysms and dissections are more commonly associated with an underlying genetic etiology. In the past several decades, in parallel with the burst of new genome sequencing technologies, a number of genetic aortopathies have been identified. These have provided important insights into the molecular mechanisms of aneurysmal disease, but pose challenges in clinical practice as there are limited consensus recommendations at this time. In this review, we aim to address the pathophysiology, clinical presentation, and treatment considerations in the key heritable thoracic aortopathies.

[PMID: 32798453 DOI: 10.1016/j.brainres.2020.147055] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 07/04/2020] [Accepted: 08/11/2020] [Indexed: 12/15/2022]
Abstract
GPR56/ADGRG1 is a member of the adhesion G-protein coupled receptor (aGPCR) family and one of the important players in the normal development of the brain. It plays a pivotal role in the diverse neurobiological processes, including cortical formation, oligodendrocyte development, and myelination. Mutations in GPR56 are known to cause brain malformation, myelination defects and are also implied in many cancers, including brain tumors. Since its identification almost two decades ago, GPR56 has emerged from an orphaned and uncharacterized GPCR to an increasingly well studied receptor. Yet, much needs to be understood about GPR56, both in terms of its molecular interactions and biological functions that may be relevant in normal health and disease. The review is focussed on the recent available knowledge of GPR56, which would give useful insights into its known and potential roles in the human brain, neurological disorders, and brain tumors like glioblastoma.

Abstract
Thoracic aortic aneurysm is typically clinically silent, with a natural history of progressive enlargement until a potentially lethal complication such as rupture or dissection occurs. Underlying genetic predisposition strongly influences the risk of thoracic aortic aneurysm and dissection. Familial cases are more virulent, have a higher rate of aneurysm growth, and occur earlier in life. To date, over 30 genes have been associated with syndromic and non-syndromic thoracic aortic aneurysm and dissection. The causative genes and their specific variants help to predict the disease phenotype, including age at presentation, risk of dissection at small aortic sizes, and risk of other cardiovascular and systemic manifestations. This genetic "dictionary" is already a clinical reality, allowing us to personalize care based on specific causative mutations for a substantial proportion of these patients. Widespread genetic sequencing of thoracic aortic aneurysm and dissection patients has been and continues to be crucial to the rapid expansion of this dictionary and ultimately, the delivery of truly personalized care to every patient.

Abstract
IMPACT STATEMENT Millions of people every year develop scars in response to skin injuries after surgery, trauma, or burns with significant undesired physical and psychological effects. This review provides an update on engineering strategies for scar-free wound healing and discusses the role of different cell types, growth factors, cytokines, and extracellular components in regenerative wound healing. The use of pro-regenerative matrices combined with engineered cells with less intrinsic potential for fibrogenesis is a promising strategy for achieving scar-free skin tissue regeneration.
