Laryngological manifestations of connective tissue diease with hypermobility such as ehlers‐danlos syndrome (EDS) are not well defined in the literature. EDS is an inherited, hetrogeneous, connective tissue disorder characterized by joint hypermobility, skin extensibility, and joint dislocations. A case series of 9 patients is presented with varying laryngological complaints. Common comorbities include postural orthostatic tachycardia syndrome (POTS), fibromyalgia, irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD)/laryngopharyngeal reflux disease (LPRD). Six patients were singers. Videostroboscopic parameters and treatment courses are described. It may be beneficial to view patients with EDS and laryngological complaints through a holistic lens as many may need interdisciplinary assessment and management.

Topics discussed include her past medical history and medications, working diagnosis, and management and outcome. Also included is a discussion about Ehlers-Danlos Syndrome.

BackgroundThe differential diagnosis of non-accidental injury during childhood includes medical conditions that predispose to skeletal fragility. Ehlers-Danlos syndrome (EDS) has been proposed as one such condition despite little objective evidence in the medical literature.ObjectiveTo investigate if EDS causes increased bone fragility during infancy and childhood.Participants and settingResidents of an 8-county region in southern Minnesota using the Rochester Epidemiology Project (REP) medical records-linkage system.MethodsThis retrospective, population-based, case-control study identified subjects with EDS from 1976 to 2015 who had complete records for at least their first year of life. Validity of diagnosis was ascertained using the 2017 International Classification of the Ehlers-Danlos Syndromes. Records were reviewed for fracture diagnoses that were characterized by age, location, type and mechanism.ResultsOf 219 potential cases, 21 had complete records for the first year of life and sufficient evidence in the medical record to support an EDS diagnosis. Of these 21, there were 14 hypermobile, 2 classical, 4 vascular, and 1 arthrochalasia EDS subtypes. 11 of 21 EDS cases (52.4%) and 15 of 63 controls (23.8%) had one or more fractures during childhood. No fractures were identified in the first year of life. Comparing cases to controls, EDS was associated with having any fractures during childhood with an odds ratio of 3.4 (95% CI: 1.20-9.66).ConclusionsWe found no evidence that infants with common forms of EDS are predisposed to more frequent fractures. Ambulatory subjects with these EDS subtypes may have a higher incidence of fractures during childhood.

Background/Objective: Spondylodysplastic Ehlers-Danlos syndrome (spEDS) is a rare subtype of the heritable connective tissue disorder characterized in the 2017 Ehlers-Danlos syndrome (EDS) nosology. Three biallelic mutations, B4GALT7, B3GALT6, and SLC39A13, confirm the diagnosis of spEDS. Hypophosphatasia (HPP) is a heritable disorder caused by a genetic sequence variation in the ALPL gene affecting bone mineralization. Common symptoms in the adult form of HPP are joint pain, muscle hypotonia, and metatarsal fractures. Here we present a case of spEDS and HPP in a patient. Case Report: A 38-year-old woman was evaluated for chronic diffuse joint pain and a low alkaline phosphatase level of 27 U/L (reference, 31-125 U/L). In addition, she presented with a history of hypermobility, limb bowing, and hyperextensible skin, prompting genetic testing for EDS and HPP. The results returned significant for a synonymous sequence variant at c.441G>A in the B4GALT7 gene indicative of spEDS. HPP was clinically diagnosed by a repeat low alkaline phosphatase level of 23 U/L and high vitamin B6 level of 24.4 ng/mL (reference, 2.1-21.7 ng/mL), despite the absence of the ALPL gene sequence variation on genetic testing. Discussion: Remarkable personal and family history of this patient suggest that co-occurrence of EDS and HPP is not merely coincidental. Given the overlapping features of muscle hypotonia and joint pain between the 2 heritable disorders, a possible relationship between the 2 may have been previously overlooked. Conclusion: Further investigation in the relationship and management of the 2 heritable diseases is warranted as enzyme replacement therapy, asfotase alfa, approved for infantile and juvenile onset of HPP may improve the symptoms shared with EDS.

Abstract The spondylodysplastic type of Ehlers–Danlos syndrome (spEDS) is caused by genetic defects in the B4GALT7 or B3GALT6 genes both deranging the biosynthesis of the glycosaminoglycan linkage region of chondroitin/dermatan sulfate and heparan sulfate proteoglycans. In this study, we have analyzed the linkage regions of urinary chondroitin sulfate proteoglycans of three siblings, diagnosed with spEDS and carrying biallelic pathogenic variants of the B3GALT6 gene. Proteoglycans were digested with trypsin, glycopeptides enriched on anion‐exchange columns, depolymerized with chondroitinase ABC, and analyzed by nLC‐MS/MS. In urine of the unaffected mother, the dominating glycopeptide of bikunin/protein AMBP appeared as only one dominating (99.9%) peak with the canonical tetrasaccharide linkage region modification. In contrast, the samples of the three affected siblings contained two different glycopeptide peaks, corresponding to the canonical tetrasaccharide and to the non‐canonical trisaccharide linkage region modifications in individual ratios of 61/38, 73/27, and 59/41. We propose that the relative distribution of glycosaminoglycan linkage regions of urinary bikunin glycopeptides may serve as a phenotypic biomarker in a diagnostic test but also as a biomarker to follow the effect of future therapies in affected individuals.

The EDS genetic condition is thought to affect both males and females equally, although most symptomatic patients are female. EDS causes a myriad of symptoms, including skin hyperextensibility and fragility, easy bruising and bleeding, joint hypermobility, subluxation, dislocation, and chronic pain. Pain is one of the most common symptoms of EDS, leading to disability and decreased quality of life. Current guidelines for treating chronic pain in EDS are lacking. Clinicians focus on a conservative multidisciplinary approach in patients with EDS, which avoids surgical interventions and its accompanying risks of morbidity and mortality. The multidisciplinary approach includes physiotherapy, occupational therapy, cognitive behavioral therapy, and pharmacologic interventions to decrease pain. This review identifies literature examining the components of this conservative multidisciplinary approach and their effectiveness across the PubMed, EMBASE, CINAHL, Web of Science, and Trip databases, using the terms “Ehlers-Danlos Syndrome AND Pain Management” that was then subsequently evaluated. The evaluation of this current literature provides weak evidence to support the efficacy of the individual components of the conservative multidisciplinary approach. Lack of alternative approaches leaves medical providers with little choice but to suggest these pain control methods, despite low-grade evidence of weak evidence of their efficacy. More research into the pathophysiology of chronic pain in EDS could help identify additional modes and rationales for therapy.Keywords: Ehlers–Danlos syndrome, conservative management, chronic pain, evidence-based medicine

The article presents a clinical case of annular elastolytic giant cell granuloma (AEGCG) in a young patient with a vascular type of EhlersDanlos syndrome. The first clinical manifestations of AEGCG appeared on the skin in the right subclavian area about two years ago. Subsequently, new rashes appeared on the skin of the upper and lower extremities up to four new foci per year. The patient underwent ambulatory therapy as a solution of calcium gluconate 10% 5.0 ml No 10 i/v in every other day; a solution of chloropyramine hydrochloride 1.0 ml No 10 i/m every other day; betamethasone + salicylic acid ointment applied to the affected areas of the skin 2 times a day for 2 weeks. The treatment was ineffective, the rashes did not regress. External therapy with tacrolimus was carried out next, 0.1% ointment 2 times a day in the form of applications for 24 weeks but also without effect. The patient by herself started to take a dietary supplement containing 400 mg of collagen in 1 tablet; 3 types of amino acids 20 mg; vitamins B2 1.1 mg; B6 1.5 mg; calcium pantothenate 5 mg 2 tablets a day during meals. A month after the start of the application, she noticed a slight paling of the rashes. At the moment, the patient is under follow up.

The article discusses the dangers of overspecialization in the field of eating disorders, highlighting the need for a more holistic approach to research and clinical care. The authors emphasize the interconnectedness of eating disorders with other psychiatric and medical conditions, advocating for a shift towards a greater focus on biology in understanding and treating these disorders. They also address the stigmas and prejudices surrounding eating disorders, suggesting that centralizing the role of biology can help combat these harmful assumptions. Overall, the article calls for a paradigm shift towards a more comprehensive and integrated approach to eating disorders to improve understanding, treatment, and recovery for individuals affected by these conditions.

This article discusses the case of a 15-year-old girl who presented with heavy periods and iron deficiency anemia. She also experienced excessive bruising, fatigue, and joint pain. After conducting various tests, it was discovered that she had a novel platelet function disorder caused by a genetic mutation in the FLNA gene. The article emphasizes the importance of genetic testing in diagnosing platelet disorders and highlights the need to assess generalized joint hypermobility in patients with bleeding symptoms.

Classical-like Ehlers–Danlos syndrome (clEDS) is an autosomal recessive disorder caused by complete absence of tenascin-X resulting from biallelic variation in TNXB. Thus far, 50 patients from 43 families with biallelic TNXB variants have been identified. Accurate detection of TNXB variants is challenging because of the presence of the pseudogene TNXA, which can undergo non-allelic homologous recombination. Therefore, we designed a genetic screening system that is performed using similar operations to other next-generation sequencing (NGS) panel analyses and can be applied to accurately detect TNXB variants and the recombination of TNXA-derived sequences into TNXB. Using this system, we identified biallelic TNXB variants in nine unrelated clEDS patients. TNXA-derived variations were found in >75% of the current cohort, comparable to previous reports. The current cohort generally exhibited similar clinical features to patients in previous reports, but had a higher frequency of gastrointestinal complications (e.g., perforation, diverticulitis, gastrointestinal bleeding, intestinal obstruction, rectal/anal prolapse, and gallstones). This report is the first to apply an NGS-based screening for TNXB variants and represents the third largest cohort of clEDS, highlighting the importance of increasing awareness of the risk of gastrointestinal complications.

Background: Ehlers-Danlos Syndrome (EDS) is a serious chronic condition that leads to diminished quality of life and psychological problems. The current study aimed to systematically reviewed the existing literature on EDS patients' health-related quality of life (HRQoL), calculate mean HRQoL value, and determine the association between demographical and publication-related characteristics with HRQoL. Methods: Four electronic databases were used to identify papers on HRQOL in adults with EDS (Scopus, Medline (by Pubmed), Epistemonikos, and Web of Science). A random-effects meta-analysis was also performed on the 36-item Short Form Survey (SF-36) measure. Results: We contained 37 studies that fulfilled the inclusion criteria. According to the SF-36 meta-analysis, EDS patients and the general population had significant differences in all HRQoL components (p0.01). In EDS patients, the Physical Component Summary (35.34/100) was more seriously impacted than the Mental Component Summary (45.21/100) in these patients. Conclusion: Individuals with EDS have significantly lower HRQoL in all aspects compared to the general population, with the physical component of wellbeing being the most pronounced disparity. Future research should look into the impact of different patient characteristics, evaluate the complications of EDS and their effects on wellbeing, and develop multiple intervention strategies to improve HRQoL.

Introduction: The purpose of this study was to explore the literature on fatigue in patients with syndromic heritable thoracic aortic disease (sHTAD), including Marfan syndrome (MFS), Loeys-Dietz syndrome (LDS), vascular Ehlers Danlos syndrome (vEDS) and other sHTADs, critically appraise and synthesize the relevant literature. We also aimed to investigate how adults with sHTAD experience and perceive fatigue, and to discuss clinical implications and direction for further research. Methods: First, a systematic review was performed by searching the published literature in all relevant databases and other sources until 20th October 2022. Second, a qualitative focus group interview study was conducted of 36 adults with sHTADs (LDS n = 11, MFS n = 14, vEDS n = 11). Results: In the systematic review, 33 articles satisfied the eligibility criteria (3 reviews and 30 primary studies). Of the primary studies: 25 dealt with adults (MFS n = 17, MFS/EDS n = 1, EDS n = 2, LDS/vEDS n = 3, different sHTADs n = 2), 5 with children (MFS n = 4, different sHTADs n = 1). Twenty-two were cross-sectional quantitative studies, 4 prospective and 4 qualitative studies. The quality of the included studies was mostly good, but many had small sample sizes, low response rates and/or participants without verified diagnosis. Despite these limitations, studies indicated high prevalence of fatigue (ranging from 37 to 89%), and fatigue was associated with both health and psychosocial aspects. Few studies found that fatigue was associated with disease-related symptoms. In the qualitative focus groups most of the participants reported that they had experienced fatigue which influenced several aspects of life. Four themes related to fatigue were elucidated: (1) different diagnoses–different fatigue?, (2) the nature of fatigue, (3) searches for causes of fatigue, (4) dealing with fatigue in daily life. The four themes seemed mutually interrelated in terms of barriers, strategies and facilitators for dealing with fatigue. The participants experienced fatigue as a consistent dilemma between self-assertion and inadequacy. Fatigue seems to influence several aspects of daily life and may be one of the most debilitating symptoms of having a sHTAD. Conclusion: Fatigue seems to negatively impact the lives of people with sHTADs and should be recognized as an important aspect in the lifelong follow-up of these patients. The life-threatening complications of sHTADs may result in emotional stress, including fatigue and the risk of developing a sedentary lifestyle. Research and clinical initiatives should consider rehabilitation interventions aiming at postponing the onset or reducing symptoms of fatigue. [ABSTRACT FROM AUTHOR]

The Ehlers--Danlos Syndromes (EDS), a group of hereditary connective tissue disorders, were classified into 13 subtypes in the 2017 International Classification. Recently, a new subtype of EDS called classical-like EDS type 2 (clEDS2), which is caused by biallelic variants in the adipocyte enhancer binding protein 1 (AEBP1) gene, was identified. We describe the 11th patient (9th family) with clEDS2, who was complicated by a critical vascular event (superior mesenteric artery aneurysm and rupture). A next-generation sequencing panel-based analysis revealed compound heterozygous variants in AEBP1: NM_001129.5:c.[2296G>T]; [2383dup], p.[(Glu766*)]; [(Glu795Glyfs*3)]. Light microscopic analyses showed increased interfibrillar spaces in the reticular dermis, a disorganized arrangement of collagen fibers, and decreased collagen content. An electron microscopic analysis showed the presence of collagen fibrils with irregular contours (flower-like appearance) and small collagen fibrils. A biochemical analysis showed reduced secretion of type I and type III procollagen. Clinical and molecular features of the current patient and all previously reported patients were reviewed comprehensively. Manifestations noted in most cases (>80%) included skin features (hyperextensibility, atrophic scars, easy bruising, excessive skin/skin folding, delayed wound healing, translucency, piezogenic papules), skeletal features (generalized joint hypermobility, dislocations/subluxations, pes planus), dental abnormalities, and neuromuscular abnormalities. Critical complications, each occurring in a single case, included superior mesenteric artery multiple aneurysm and rupture, aortic root dilation requiring surgery, and bowel rupture. Most AEBP1 variants were predicted or experimentally confirmed to lead to nonsense-mediated mRNA decay, whereas one variant resulted in a protein that was retained intracellularly and not secreted. Clinical, molecular, pathological, and biochemical features of the current patient, as well as a review of all previously reported patients, suggest the importance of the aortic carboxypeptidase-like protein encoded by AEBP1 in collagen fibrillogenesis.

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 FROM AUTHOR]

Background: Hypermobile Ehlers–Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD) are debilitating conditions. Diagnosis is currently clinical in the absence of biomarkers, and criteria developed for adults are difficult to use in children and biologically immature adolescents. Generalized joint hypermobility (GJH) is a prerequisite for hEDS and generalized HSD. Current literature identifies a large proportion of children as hypermobile using a Beighton score ≥ 4 or 5/9, the cut off for GJH in adults. Other phenotypic features from the 2017 hEDS criteria can arise over time. Finally, many comorbidities described in hEDS/HSD are also seen in the general pediatric and adolescent population. Therefore, pediatric specific criteria are needed. The Paediatric Working Group of the International Consortium on EDS and HSD has developed a pediatric diagnostic framework presented here. The work was informed by a review of the published evidence. Observations: The framework has 4 components, GJH, skin and tissue abnormalities, musculoskeletal complications, and core comorbidities. A Beighton score of ≥ 6/9 best identifies children with GJH at 2 standard deviations above average, based on published general population data. Skin and soft tissue changes include soft skin, stretchy skin, atrophic scars, stretch marks, piezogenic papules, and recurrent hernias. Two symptomatic groups were agreed: musculoskeletal and systemic. Emerging comorbid relationships are discussed. The framework generates 8 subgroups, 4 pediatric GJH, and 4 pediatric generalized hypermobility spectrum disorders. hEDS is reserved for biologically mature adolescents who meet the 2017 criteria, which also covers even rarer types of Ehlers–Danlos syndrome at any age. Conclusions: This framework allows hypermobile children to be categorized into a group describing their phenotypic and symptomatic presentation. It clarifies the recommendation that comorbidities should be defined using their current internationally accepted frameworks. This provides a foundation for improving clinical care and research quality in this population. [ABSTRACT FROM AUTHOR]

A wide variety of cutaneous disorders present with annular (ringlike) skin lesions, and some of them carry rheumatologic implications because they may involve the joints or belong to the spectrum of connective tissue diseases. The diagnosis of an annular rheumatologic skin disease is possible with a correct clinicopathologic correlation, with a correct anamnesis of the patient, with the evaluation of systemic symptoms, laboratory and instrumental investigations, and finally with a cutaneous biopsy.

Musculocontractural Ehlers–Danlos syndrome (mcEDS) is a heritable connective tissue disorder characterized by multiple congenital malformations and progressive connective-tissue-fragility-related manifestations in the cutaneous, skeletal, cardiovascular, visceral, ocular, and gastrointestinal systems. It is caused by pathogenic variants in the carbohydrate sulfotransferase 14 gene (mcEDS-CHST14) or in the dermatan sulfate epimerase gene (mcEDS-DSE). As gastrointestinal complications of mcEDS-CHST14, diverticula in the colon, small intestine, or stomach have been reported, which may lead to gastrointestinal perforation, here, we describe sisters with mcEDS-CHST14, who developed colonic perforation with no evidence of diverticula and were successfully treated through surgery (a resection of perforation site and colostomy) and careful postoperative care. A pathological investigation did not show specific abnormalities of the colon at the perforation site. Patients with mcEDS-CHST14 aged from the teens to the 30s should undergo not only abdominal X-ray photography but also abdominal computed tomography when they experience abdominal pain.

Introduction: AEBP1-related classical-like EDS (clEDS type 2) is a rare type of Ehlers-Danlos syndrome (EDS) that was first reported in 2016. There are overlapping clinical features with TNXB-related classical-like EDS (or clEDS type 1), including skin hyperextensibility, joint hypermobility, and easy bruising. There are currently nine reported individuals with AEBP1-related clEDS type 2. This report confirms previous findings and provides additional clinical and molecular data on this group of individuals. Materials and methods: Two individuals (P1 and P2), with features of a rare type of EDS, were clinically assessed in the London national EDS service and underwent genetic testing. Results: Genetic testing in P1 revealed likely pathogenic AEBP1 variants: c.821del: p. (Pro274Leufs*18) and c.2248T>C:p. (Trp750Arg). In P2 pathogenic AEBP1 variants, c.1012G>T:p. (Glu338*) and c.1930C>T:p. (Arg644*) were identified. Discussion: These two individuals increased the reported number of individuals with AEBP1-related clEDS to 11 (six females and five males). There are shared features with previously reported individuals, including hypermobility (11/11), skin hyperextensibility (11/11), presence of atrophic scarring (9/11), and easy bruising (10/11). In P1, a chronic right vertebral artery dissection, mild dilatation of the splenic artery, aberrant subclavian artery, and tortuous iliac arteries were observed at the age of 63 years. Cardiovascular disease has been reported, including mitral valve prolapse (4/11), peripheral arterial disease (1/11), and aortic root aneurysm requiring surgical intervention (1/11). Hair loss has been reported in 6/11 individuals (five females and one male), only one of which was documented to have a formal diagnosis of androgenetic alopecia, while other individuals were described as having thinning of hair, male pattern hair loss, or unspecified alopecia. Conclusion: The clinical features of individuals with AEBP1-related EDS have not been fully elucidated yet. Hair loss is present in 6/11 individuals with AEBP1-related clEDS and appears to be a feature of this condition. This is the first time hair loss has been formally reported as a characteristic feature in a rare type of EDS. Cardiovascular surveillance seems warranted in this condition because 2/ 11 individuals have evidence of arterial aneurysm and/or dissection. Further descriptions of affected individuals are necessary to update diagnostic criteria and management guidelines. [ABSTRACT FROM AUTHOR]

Objective: Joint hypermobility in Ehlers‐Danlos Syndromes (EDS) predisposes persons with EDS to frequent subluxations and dislocations, chronic arthralgia, and soft‐tissue rheumatism. Epidemiologic trends of rheumatologic conditions among persons with EDS are lacking. Prescription claims databases can reflect underlying disease burdens by using medication claims as disease proxies. We examined the prevalence of prescription claims for commonly prescribed immunomodulator and antiinflammatory (IMD) drugs among persons with EDS compared with their matched control person, and hypothesized peripubertal increases among female persons with EDS. Methods: We compared the percentages of IMD drug prescription claims among 3,484 persons with EDS (ages 5–62 years) against their age‐, sex‐, state of residence‐, and earliest claim date–matched control persons using 10 years (2005–2014) of private prescription claims data and a minimum 2‐year enrollment inclusion criterion. Results: Our cohort comprised 70% adults and 74% female persons. At least 1 IMD medication was prescribed to 65.4% of persons with EDS compared with 47.4% of control persons. We observed 1.3 to 4.2 times higher odds (P < 0.0001) for 5 out of 6 IMD drug classes among persons with EDS compared with matched control persons, except for biologic agents (conditional odds ratio 1.3, 95% confidence interval 0.8–2.0). Peripubertal increases were observed for nonsteroidal antiinflammatory drugs, oral, and injectable steroids. Conclusions: To our knowledge, our study is the first to examine the full range of IMD drug prescription claim trends among persons with EDS. We believe our research findings can have notable diagnostic and management implications for EDS patients who present with multiple comorbidities and generally require a more granular assessment of their medical conditions.

A newborn girl had, from two weeks on, small bruises on varying body locations, but not on her chest. Her Armenian grandmother easily bruised, too. Her mother was diagnosed with hypermobility-type Ehlers-Danlos-Syndrome (hEDS), an autosomal dominant connective tissue disorder, with a 50% inheritance probability. Referral to a University Medical Center located "Dutch Expertise Center for Child Abuse" resulted (prior to consultation) in physical abuse suspicion. Protocol-based skeletal X-rays showed three healed, asymptomatic rib fractures. A protocol-based Bayesian likelihood ratio guesstimation gave 10–100, erroneously used to suggest a 10–100 times likelier non-accidental-than-accidental cause. Foster care placement followed, even in a secret home, where she also bruised, suggesting hEDS inheritance. Correct non-accidental/accidental Bayes' probability of symptoms is (likelihood ratio) × (physical abuse incidence). From the literature, we derived an infant abuse incidence between about ≈0.0009 and ≈0.0026 and a likelihood ratio of <5 for bruises. For rib fractures, we used a zero likelihood ratio, arguing their cause was birth trauma from the extra delivery pressure on the chest, combined with fragile bones as the daughter of an hEDS-mother. We thus derived a negligible abuse/accidental probability between <5 × 0.0009 <0.005 and <5 × 0.0026 <0.013. The small abuse incidence implies that correctly using Bayes' theorem will also miss true infant physical abuse cases. Curiously, because likelihood ratios assess how more often symptoms develop if abuse did occur versus non-abuse, Bayes' theorem then implies a 100% infant abuse incidence (unwittingly) used by LECK. In conclusion, probabilities should never replace differential diagnostic procedures, the accepted medical method of care. Well-known from literature, supported by the present case, is that (child abuse pediatrics) physicians, child protection workers, and judges were unlikely to understand Bayesian statistics. Its use without statistics consultation should therefore not have occurred. Thus, Bayesian statistics, and certainly (misused) likelihood ratios, should never be applied in cases of physical child abuse suspicion. Finally, parental innocence follows from clarifying what could have caused the girl's bruises (inherited hEDS), and rib fractures (birth trauma from fragile bones). [ABSTRACT FROM AUTHOR]

Purpose: To evaluate ocular motility (OM) abnormalities associated with Ehlers-Danlos Syndrome (EDS). Materials and methods: In this cross-sectional observational study, patients with EDS underwent a complete orthoptic examination. The following orthoptic tests were performed: corneal light reflex test, stereoscopic test, cover test, OM assessment, evaluation of eye pain in different gaze positions and red filter test for diplopia. Results: The corneal light reflex test at 33 cm showed an intermittent divergent deviation in 31.7% of patients and an intermittent horizontal deviation associated with a vertical deviation in 4.9% of patients. A manifest strabismus was observed in 2.4% of patients, whereas 2.4% of patients showed a microstrabismus. The corneal light reflex test at 5 m revealed microstrabismus in 9.8% and manifest strabismus in 2.4% of our patients. Moreover, intermittent exotropia was observed in 2.4% of cases. No significant alterations involving the inferior rectus and the superior oblique muscles were observed. Significant associations were observed between medial rectus muscle deficit of both eyes with pain (p = 0.020) and diplopia (p = 0.014). Furthermore, a significant association between lateral rectus muscle alteration of both eyes and pain was observed (p = 0.004). Conclusions: Our results show various OM alterations in patients with EDS, specifically superior and medial rectus muscle hypofunction. A full orthoptic evaluation in these patients is recommendable to detect OM involvement and possible ligamentous laxity changes over time through an accurate OM assessment. [ABSTRACT FROM AUTHOR]

Background: Ehlers-Danlos Syndrome (EDS) is a serious chronic condition that leads to diminished quality of life and psychological problems. The current study aimed to systematically reviewed the existing literature on EDS patients' health-related quality of life (HRQoL), calculate mean HRQoL value, and determine the association between demographical and publication-related characteristics with HRQoL. Methods: Four electronic databases were used to identify papers on HRQOL in adults with EDS (Scopus, Medline (by Pubmed), Epistemonikos, and Web of Science). A random-effects meta-analysis was also performed on the 36-item Short Form Survey (SF-36) measure. Results: We contained 37 studies that fulfilled the inclusion criteria. According to the SF-36 metaanalysis, EDS patients and the general population had significant differences in all HRQoL components (p<0.01). In EDS patients, the Physical Component Summary (35.34/100) was more seriously impacted than the Mental Component Summary (45.21/100) in these patients. Conclusion: Individuals with EDS have significantly lower HRQoL in all aspects compared to the general population, with the physical component of wellbeing being the most pronounced disparity. Future research should look into the impact of different patient characteristics, evaluate the complications of EDS and their effects on wellbeing, and develop multiple intervention strategies to improve HRQoL.

Under physiological conditions, skin mast cells play an important role as guardians that quickly react to stimuli that disturb homeostasis. These cells efficiently support, fight infection, and heal the injured tissue. The substances secreted by mast cells allow for communication inside the body, including the immune, nervous, and blood systems. Pathologically non-cancerous mast cells participate in allergic processes but also may promote the development of autoinflammatory or neoplastic disease. In this article, we review the current literature regarding the role of mast cells in autoinflammatory, allergic, neoplastic skin disease, as well as the importance of these cells in systemic diseases with a pronounced course with skin symptoms.

Introduction. Tumor-induced osteomalacia (TIO) is a rare paraneoplastic disorder where patients present with hypophosphatemia, chronic diffuse bone pain, and occasionally fractures. Benign phosphaturic mesenchymal tumors (PMT) are responsible for the TIO and are largely soft tissue tumors. Cases. Two male patients with TIO secondary to PMT were reported—one in the bony scapula and the other in the plantar foot soft tissue. The first case describes a 63-year-old Caucasian male, who sustained an intertrochanteric proximal femur stress fracture and approximately two years of diffuse bone pain and hypophosphatemia. Wide excision of a left scapula boney lesion resulted in immediate resolution of his electrolyte abnormalities and bone pain. Case 2 describes a 58-year-old male with four years of multifocal bone pain and atraumatic fractures. A 68Ga-DOTATATE-positron emission tomography/computed tomography (PET/CT) scan identified a soft tissue tumor in his plantar foot, which was ultimately excised. He also experienced near immediate resolution of his pain and no additional fractures. Conclusion. TIO is a rare condition presenting with chronic multifocal bone pain, stress fractures, and hypophosphatemia. These two cases highlight that the causative tumor may originate in soft tissue or bone. Furthermore, a high index of suspicion, along with fibroblast growth factor-23 testing and DOTATATE-PET/CT localization, can help with diagnosis and minimize treatment delays. [ABSTRACT FROM AUTHOR]

Case: A 71-year-old woman with Ehlers-Danlos syndrome suffered an atraumatic obturator dislocation status post direct anterior total hip arthroplasty. A closed reduction under conscious sedation was attempted, but was unsuccessful. Repeat closed reduction under full general anesthesia with paralysis and fluoroscopic guidance was successful at reducing the femoral prosthesis out of the pelvis and back into an appropriate position. Conclusion: Atraumatic obturator dislocations after total hip arthroplasty are exceedingly rare. General anesthesia with full paralysis is helpful for a successful closed reduction, and open reduction may be necessary to remove the femoral prosthesis from the pelvis. [ABSTRACT FROM AUTHOR]

Collagen is the building block for the extracellular matrix in bone, teeth and other fibrous tissues. Osteogenesis imperfecta (OI), or brittle bone disease, is a heritable disorder that results from defective collagen synthesis or metabolism, resulting in bone fragility. The dental manifestation of OI is dentinogenesis imperfecta (DI), a genetic disorder that affects dentin structure and clinical appearance, with a characteristic feature of greyish-brown discolouration. The aim of this study was to conduct a systematic review to identify and/or define any ultrastructural changes in dentinal collagen in DI. Established databases were searched: Cochrane Library, OVID Embase, OVID Medline and PubMed/Medline. Search strategies included: Collagen Ultrastructure, DI and OI. Inclusion criteria were studies written in English, published after 1990, that examined human dental collagen of teeth affected by DI. A Cochrane data extraction form was modified and used for data collection. The final dataset included seventeen studies published from 1993 to 2021. The most prevalent findings on collagen in DI teeth were increased coarse collagen fibres and decreased fibre quantity. Additional findings included changes to fibre orientation (i.e., random to parallel) and differences to the fibre organisation (i.e., regular to irregular). Ultrastructural defects and anomalies included uncoiled collagen fibres and increased D-banding periodicity. Studies in collagen structure in DI reported changes to the surface topography, quantity, organisation and orientation of the fibres. Moreover, ultrastructural defects such as the packing/coiling and D-banding of the fibrils, as well as differences in the presence of other collagens are also noted. Taken together, this study provides an understanding of the changes in collagen and its impact on clinical translation, paving the way for innovative treatments in dental treatment.

Background: Ehlers–Danlos syndrome (EDS) is a phenotypically and genetically heterogeneous group of connective tissue disorders. Currently, diagnosis of EDS is based on a series of clinical and genetic tools. On the other hand, the hypermobile form has not yet been characterized from a genetic point of view: it is considered a part of a continuous spectrum of phenotypes, ranging from isolated non syndromic joint hypermobility, through to the recently defined hypermobility spectrum disorders (HSD). The aim of this study is to characterize the pain symptom that is not considered among the diagnostic criteria but is relevant to what concerns the quality of life of patients with EDS. (2) Methods: A review of the literature was performed on two medical electronic databases (PubMed and Embase) on 20 December 2022. Study selection and data extraction were achieved independently by two authors and the following inclusion criteria were determined a priori: published in the English language and published between 2000 and 2022. (3) Results: There were fifty eligible studies obtained at the end of the search and screen process. Pain is one of the most common symptoms found in Ehlers–Danlos (ED) patients. Different causes seem to be recognized in different phases of the syndrome. (4) Conclusions: Pain is a nonspecific symptom and cannot be considered among the diagnostic criteria, but it is a negative predictive factor in the quality of life of patients with EDS. Therefore, proper evaluation and treatment is mandatory. [ABSTRACT FROM AUTHOR]

An aberrant subclavian artery (ASA) (or lusoria) is the most common congenital anomaly of the aortic arch (0.5%-2.2%; female-to-male ratio 2:1 to 3:1). ASA can become aneurysmal and result in dissection, involving Kommerell's diverticulum when present and the aorta. Data of its significance in genetic arteriopathies are not available. The purpose of this study was to assess the prevalence and complications of ASA in gene-positive and -negative nonatherosclerotic arteriopathies. The series includes 1,418 consecutive patients with gene-positive (n = 854) and gene-negative arteriopathies (n = 564) diagnosed as part of institutional work-up for nonatherosclerotic syndromic and nonsyndromic arteriopathies. Comprehensive evaluation includes genetic counseling, next-generation sequencing multigene testing, cardiovascular and multidisciplinary assessment, and whole-body computed tomography angiography. ASA was found in 34 of 1,418 cases (2.4%), with a similar prevalence in gene-positive (n = 21 of 854, 2.5%) and gene-negative (n = 13 of 564, 2.3%) arteriopathies. Of the former 21 patients, 14 had Marfan syndrome, 5 had Loeys-Dietz syndrome, 1 had type-IV Ehlers-Danlos syndrome, and 1 had periventricular heterotopia type 1. ASA did not segregate with genetic defects. Dissection occurred in 5 of 21 patients with genetic arteriopathies (23.8%; 2 Marfan syndrome and 3 Loeys-Dietz syndrome), all with associated Kommerell's diverticulum. No dissections occurred in gene-negative patients. At baseline, none of the 5 patients with ASA dissection fulfilled criteria for elective repair according to guidelines. The risk of complications of ASA is higher in patients with genetic arteriopathies and is difficult to predict. In these diseases, imaging of the supra-aortic trunks should enter baseline investigations. Determination of precise indications for repair can prevent unexpected acute events such as those described. [Display omitted] [ABSTRACT FROM AUTHOR]

Introduction: Vascular Ehlers-Danlos syndrome (vEDS) is an autosomal dominant inherited connective tissue condition, characterized by generalized tissue fragility with an increased risk of arterial dissection and hollow organ rupture. In women with vEDS, pregnancy and childbirth carry significant risks of both morbidity and mortality. The Human Fertilisation and Embryology Authority has approved vEDS for pre-implantation genetic diagnosis (PGD), given the potential for life-limiting complications. PGD avoids implantation of embryos that are affected by specific disorders by carrying out genetic testing (either for a familial variant or whole gene) and selecting unaffected embryos prior to implantation. Case: We present an essential clinical update to the only published clinical case of a woman with vEDS undergoing PGD with surrogacy, initially through stimulated in vitro fertilization (IVF) and in vitro maturation (IVM) and subsequently through natural IVF. Discussion: In our experience, a subset of women with vEDS do wish to have biological, unaffected children through PGD despite being aware of the risks of pregnancy and delivery. Given the clinical heterogeneity in vEDS, these women could be considered on a case-by-case basis for PGD. Controlled studies with comprehensive patient monitoring evaluating the safety of PGD are essential to equitable healthcare provision. [ABSTRACT FROM AUTHOR]

Tenascin-X (TNX) is an extracellular matrix glycoprotein for which a deficiency results in a recessive form of classical-like Ehlers-Danlos syndrome (clEDS), a heritable connective tissue disorder with hyperextensible skin without atrophic scarring, joint hypermobility, and easy bruising. Notably, patients with clEDS also suffer from not only chronic joint pain and chronic myalgia but also neurological abnormalities such as peripheral paresthesia and axonal polyneuropathy with high frequency. By using TNX-deficient (Tnxb-/-) mice, well-known as a model animal of clEDS, we recently showed that Tnxb-/- mice exhibit hypersensitivity to chemical stimuli and the development of mechanical allodynia due to the hypersensitization of myelinated A-fibers and activation of the spinal dorsal horn. Pain also occurs in other types of EDS. First, we review the underlying molecular mechanisms of pain in EDS, especially that in clEDS. In addition, the roles of TNX as a tumor suppressor protein in cancer progression have been reported. Recent in silico large-scale database analyses have shown that TNX is downregulated in various tumor tissues and that high expression of TNX in tumor cells has a good prognosis. We describe what is so far known about TNX as a tumor suppressor protein. Furthermore, some patients with clEDS show delayed wound healing. Tnxb-/- mice also exhibit impairment of epithelial wound healing in corneas. TNX is also involved in liver fibrosis. We address the molecular mechanism for the induction of COL1A1 by the expression of both a peptide derived from the fibrinogen-related domain of TNX and integrin a11. [ABSTRACT FROM AUTHOR]

Objectives: Migraine is one of the most frequent clinical manifestations of hypermobile Ehlers-Danlos syndrome (hEDS). The comorbidity between these two diseases has been only partially investigated. We aimed to observe whether neurophysiological alterations described inmigraineurs in visual evoked potentials (VEPs) were present in hEDS patients with migraine. Methods: We enrolled 22 hEDS patients with migraine (hEDS) and 22 non-hEDS patients withmigraine (MIG), with and without aura (according to ICHD-3), as well as 22 healthy controls (HC). Repetitive pattern reversal (PR)-VEPs were recorded in basal conditions in all participants. During uninterrupted stimulation, 250 cortical responses were recorded (4,000Hz sample rate) and divided into epochs of 300ms after the stimulus. Cerebral responses were divided into five blocks. The habituation was calculated as the slope interpolating the amplitudes in each block, for both the N75-P100 and P100-N145 components of PR-VEP. Results: We observed a significant habituation deficit of the P100-N145 component of PR-VEP in hEDS compared to HC (p = 0.002), unexpectedly more pronounced than in MIG. We observed only a slight habituation deficit of N75-P100 in hEDS, with a slope degree that was intermediate between MIG and HC. Discussion: hEDS patients withmigraine presented an interictal habituation deficit of both VEPs components like MIG. Pathophysiological aspects underlying the pathology could account for the peculiar pattern of habituation in hEDS patients withmigraine characterized by a pronounced habituation deficit in the P100-N145 component and a less clear-cut habituation deficit in the N75-P100 component with respect to MIG.

Periodontal Ehlers-Danlos syndrome (pEDS) is an autosomal dominant disorder characterized by early-onset periodontitis leading to premature loss of teeth, lack of attached gingiva and thin and fragile gums leading to gingival recession. Connective tissue abnormalities of pEDS typically include easy bruising, pretibial plaques, distal joint hypermobility, hoarse voice, and less commonly manifestations such as organ or vessel rupture. pEDS is caused by heterozygous missense mutations in C1R and CIS genes of the classical complement C1 complex. Previously we showed that pEDS pathogenic variants trigger intracellular activation of C1r and/or C1s, leading to extracellular presence of activated C1s. However, the molecular link relating activated C1r and C1s proteases to the dysregulated connective tissue homeostasis in pEDS is unknown. Using cell- and molecular-biological assays, we identified activated C1s (aC1s) as an enzyme which degrades collagen I in cell culture and in in vitro assays. Matrix collagen turnover in cell culture was assessed using labelled hybridizing peptides, which revealed fast and comprehensive collagen protein remodeling in patient fibroblasts. Furthermore, collagen I was completely degraded by aC1s when assays were performed at 40°C, indicating that even moderate elevated temperature has a tremendous impact on collagen I integrity. This high turnover is expected to interfere with the formation of a stable ECM and result in tissues with loose compaction a hallmark of the EDS phenotype. Our results indicate that pathogenesis in pEDS is not solely mediated by activation of the complement cascade but by inadequate C1s-mediated degradation of matrix proteins, confirming pEDS as a primary connective tissue disorder.

Musculocontractural Ehlers–Danlos syndrome, caused by biallelic loss-of-function variants for dermatan sulfate epimerase (mcEDS-DSE), is a rare connective tissue disorder. Eight patients with mcEDS-DSE have been described with ocular complications, including blue sclera, strabismus, high refractive errors, and elevated intraocular pressure. However, a case with rhegmatogenous retinal detachment (RRD) has not been reported. We report our findings in a 24-year-old woman who was diagnosed with mcEDS-DSE in childhood and presented to our clinic with an RRD in the left eye. The RRD extended to the macula and was associated with an atrophic hole. The patient underwent scleral buckling surgery and cryopexy with drainage of subretinal fluid through a sclerotomy under local anesthesia. The sclera did not appear blue but was very thin at the sclerotomy site. The patient developed frequent bradycardia during the surgery. Subretinal or choroidal hemorrhages were not observed intraoperatively; however, a peripapillary hemorrhage was observed one day after operation. The retina was reattached postoperatively, and the peripapillary hemorrhage was absorbed after one month. The peripapillary retinal hemorrhages, thin sclera, and bradycardia were most likely due to the fragility of the eye. The genetic diagnosis of mcEDS-DSE played an important role before and during the surgery by alerting the surgeons to possible surgical complications due to the thin sclera. [ABSTRACT FROM AUTHOR]

Aneurysmal lesions are commonly seen in Ehlers‐Danlos Syndrome (EDS). To better identify the regional and vessel‐specific spectrum of aneurysms in different subtypes of EDS, we performed a systematic review. We searched Medline for relevant studies from 1963 to April 2022. Studies providing a report of any EDS subtype by genetic diagnosis, histologic analysis, or clinical criteria were included. A total of 448 patients from 220 studies were included. 720 vessel‐specific aneurysms were reported: 386 in the abdominopelvic area, 165 in the intracranial region, 98 in the thorax, 2 in the extremities, and 6 in the venous system. In 27 out of the 65 patients with ruptured aneurysms, the ruptured aneurysm was the initial presentation. Multiple aneurysms were present in 163 out of 249 patients who had been systematically evaluated for other locations of aneurysms. The head and neck and abdominopelvic regions are two potential foci for aneurysm formation in patients with EDS. The aneurysm development in EDS is not confined to arteries; the venous system and cardiac septa may also be affected. Many patients develop multiple aneurysms, either at the time of the initial presentation or throughout their lifetime and aneurysm formation or rupture may be the first presentation of EDS.

Musculocontractural Ehlers–Danlos syndrome caused by mutations in the carbohydrate sulfotransferase 14 gene (mcEDS-CHST14) is a heritable connective tissue disorder characterized by multiple congenital malformations and progressive connective tissue fragility-related manifestations in the cutaneous, skeletal, cardiovascular, visceral, and ocular systems. Progressive skeletal deformities are among the most frequent and serious complications affecting the quality of life and activities of daily living in patients. After establishing induced pluripotent stem cells (iPSCs) from cultured skin fibroblasts of three patients with mcEDS-CHST14, we generated a patient iPSC-based human osteogenesis model and performed an in vitro assessment of the phenotype and pathophysiology of skeletal deformities. Patient-derived iPSCs presented with remarkable downregulation of osteogenic-specific gene expression, less alizarin red staining, and reduced calcium deposition compared with wild-type iPSCs at each stage of osteogenic differentiation, including osteoprogenitor cells, osteoblasts, and osteocytes. These findings indicated that osteogenesis was impaired in mcEDS-CHST14 iPSCs. Moreover, the decrease in decorin (DCN) expression and increase in collagen (COL12A1) expression in patient-derived iPSCs elucidated the contribution of CHST14 dysfunction to skeletal deformities in mcEDS-CHST14. In conclusion, this disease-in-a-dish model provides new insight into the pathophysiology of EDS and may have the potential for personalized gene or drug therapy. [ABSTRACT FROM AUTHOR]

Background and purpose: Ehlers–Danlos syndromes are hereditary disorders of connective tissue that are characterized by joint hypermobility, skin hyperextensibility and tissue fragility. The most common subtype is the hypermobile type. In addition to symptoms of small fibre neuropathy (SFN) due to damage to the small peripheral nerve fibres, with degeneration of the distal nerve endings, autonomic disorders such as postural tachycardia syndrome (PoTS) are frequently reported features in patients with hypermobile Ehlers–Danlos syndrome (hEDS). To date, the underlying pathophysiological mechanisms are still not completely understood. Study Purpose: To better understand pathophysiological mechanisms of small fiber neuropathy and autonomic neuropathy in hypermobile Ehlers‐Danlos Syndromes. Methods: We prospectively investigated 31 patients with hEDS compared to 31 healthy controls by using skin biopsy, quantitative sensory testing, tilt‐table testing, the painDetect, Small Fibre Neuropathy Screening List and the COMPASS‐31 (Composite Autonomic Symptom Score 31) questionnaire. Results: Nineteen (61%) patients with hEDS were diagnosed with SFN, and 10 (32%) fulfilled the criteria for PoTS. Patients with hEDS had significantly higher heart rates than controls. According to quantitative sensory testing, these patients had generalized thermal and tactile hypesthesia. Skin biopsy revealed significantly reduced intraepithelial nerve fibre density proximally (thigh) and distally (lower leg) in patients compared to controls. This was consistent with various complaints of pain and sensory disturbances in both the proximal and distal body regions. Conclusion: These results confirm histologically proven SFN as a common feature in patients with hEDS, revealing a generalized distribution of nerve fibre loss. Regarding the frequently reported autonomic and neuropathic dysfunctions, the findings support SFN as an important, but not the only, underlying pathomechanism. [ABSTRACT FROM AUTHOR]

We reported a detailed obstetric course of a Japanese patient with Ehlers–Danlos syndrome (EDS) caused by biallelic pathogenic variants in the AEBP1 gene. She was diagnosed with classical EDS at 3 years of age. At 33 years, whole‐exome sequencing revealed a homozygous nonsense variant (c.1894C > T:p.Arg632*) in AEBP1. This is the 10th case of AEBP1‐related EDS (classical‐like EDS type 2) and the first in Japan. She was managed as an inpatient at our hospital beginning at 20 weeks of gestation because of the possibility of high‐risk pregnancy. She experienced painful urinary retention, migraines, and threatened premature labor. She delivered a healthy female via elective caesarean section at 32 weeks of gestation. She was treated in the intensive care unit for severe paralytic ileus, postoperatively. Conservative therapy resulted in favorable outcomes, and she was safely discharged on postdelivery day 22nd.
