Abstract
PURPOSE To determine retinal detachment (RD) risk factors after lens removal surgery in children with Marfan syndrome (MS). DESIGN Retrospective, case control study. METHODS This was an institutional case series including children (age <18 years) with MS who underwent lens removal surgery. Clinical and surgical characteristics were extracted from the children's electronic files: age, axial length (AL), gender, number of surgeries received, intraocular lens (IOL) implantation at the first surgery, complete removal of the capsular bag, and final best-corrected visual acuity. Risk factors associated with RD occurrence were identified. RESULTS Among 158 eyes included (85 children), 35 eyes (22.2%) developed RD during follow-up. Bilateral detachment occurred in 11 patients (45.8%). Age at the time of the lens removal surgery was not different between groups. Children in the RD group had a higher AL (P < .001), longer follow-up, IOL implantation, and capsular residue. Multivariate analysis identified capsular residue (odds ratio, 16.8; 95% CI, 1.9-148.8; P = .01) and AL (odds ratio, 1.3; 95% CI, 1.01-1.7; P = .03) as predictors for RD. CONCLUSIONS Children with MS and increased AL were more likely to develop an RD after lens surgery. When considering lens removal surgery in a pediatric population presenting with MS, a complete capsular removal seemed to be the safer option regarding RD risk.

Abstract
Marfan syndrome (MFS) is a connective tissue disorder affecting the cardiovascular, ocular, and skeletal system, which may be accompanied by psychological features. This study aimed to determine the prevalence of fatigue, anxiety, and symptoms of depression in MFS patients, and to assess the degree to which sociodemographic and clinical variables are associated with fatigue and psychological aspects. The prevalence of fatigue, anxiety, and symptoms of depression were assessed in two cohorts of MFS patients and compared with healthy controls. The checklist individual strength (CIS), and hospital anxiety and depression scale (HADS) questionnaires were utilized. Medical status was assessed (family history of MFS, aortic root dilatation >40 mm, previous aortic surgery, aortic dissection, chronic pain, skeletal involvement, and scoliosis). Severe fatigue was experienced by 37% of the total MFS cohort (n = 155). MFS patients scored significantly higher on the CIS questionnaire, concerning severe fatigue, as compared with the general Dutch population (p < 0.0001). There were no differences in HADS anxiety or depression scores. In older MFS patients, with a more severe cardiovascular phenotype, chronic pain, and a higher unemployment rate, significantly more symptoms of depression were observed, when compared with the general population (p = 0.027) or compared with younger MFS patients (p = 0.026). Multivariate analysis, showed that anxiety was associated with chronic pain (p = 0.022) and symptoms of depression with unemployment (p = 0.024). MFS patients report significantly more severe fatigue as compared with the general population. Since the cause of fatigue is unclear, more research may be needed. Psychological intervention, for example, cognitive behavioral therapy, may contribute to a reduction in psychological symptoms.

Abstract
Purpose of Review
Marfan syndrome (MFS) is an autosomal dominant heritable disorder of fibrillin-1 (FBN1) with predominantly ocular, cardiovascular, and musculoskeletal manifestations that has a population prevalence of approximately 1 in 5–10,000 (Chiu et al. Mayo Clin Proc. 89(1):34–42, 146, Dietz 3, Loeys et al. J Med Genet. 47(7):476–85, 4). Recent Findings The vascular complications of MFS still pose the greatest threat, but effective management options, such as regular cardiac monitoring and elective surgical intervention, have reduced the risk of life-threatening cardiovascular events, such as aortic dissection. Although cardiovascular morbidity and mortality remains high, these improvements in cardiovascular management have extended the life expectancy of those with MFS by perhaps 30–50 years from an estimated mean of 32 years in 1972 (Dietz 3, Gott et al. Eur J Cardio-thoracic Surg. 10(3):149–58, 147, Murdoch et al. N Engl J Med. 286(15):804–8, 148). The musculoskeletal manifestations of MFS, which to date have received less attention, can also have a significant impact on the quality of life and are likely to become more important as the age of the Marfan syndrome population increases (Hasan et al. Int J Clin Pract. 61(8):1308–1320, 127). In addition, musculoskeletal manifestations are often critically important in the diagnosis of MFS. Summary Here, we review the main clinically relevant and diagnostically useful musculoskeletal features of MFS, which together contribute to the “systemic features score” (referred to hereafter as systemic score), part of the revised Ghent nosology for MFS. We discuss current treatment strategies and highlight the need for a multidisciplinary approach to diagnosis and management. Finally, we review new pharmacological approaches that may be disease modifying and could help to improve the outcome for individuals with this syndrome.

Abstract
Because of the widespread distribution of fibrillin 1 in the body, Marfan syndrome (MFS) affects virtually every system. The expression of this single dominantly inherited gene is variable within a family, and between families. There is some genotype-phenotype correlation which is helpful in guiding long-term prognosis, and management. In general gene mutations have been reported in clusters, with those having mainly ocular manifestations occurring in exons 1 to 15 of this 65-exon gene; those causing cardiac problems often involving cysteine replacement in a calcium binding EGF-like sequence; the most severe mutations occurring in exons 25-32, causing neonatal MFS diagnosed at birth, and severe enough to cause death frequently before the age of 2. Other correlations will certainly be found in future. This condition is progressive, and the manifestations unfold according to age. For example, if the lens is going to dislocate this usually occurs by age 10; scoliosis usually presents itself between the ages of 8 and 15; height should be monitored carefully between the onset of puberty and cessation of growth approximately age 17 or 18. Holistic care should be offered by one doctor who oversees the patient's welfare. This should be a paediatrician, paediatric cardiologist, or general practitioner in the case of an affected child. Thereafter, the physician in charge of the most seriously affected system should be aware that other systems need to be managed through a referral network.

Abstract
The clinical manifestations of Marfan syndrome frequently cause pain. This study aimed to characterize pain in a cohort of adults with Marfan syndrome and investigate demographic, physical, and psychological factors associated with pain and pain-related disability. Two hundred and forty-five participants (73% female, 89% non-Hispanic white, 90% North American) completed an online questionnaire assessing clinical features of Marfan syndrome, pain severity, pain-related disability, physical and mental health, depressive symptoms, pain catastrophizing, and insomnia. Eighty-nine percent of respondents reported having pain with 28% of individuals reporting pain as a presenting symptom of Marfan syndrome. Almost half of individuals reported that pain has spread from its initial site. Participants in our study reported poor physical and mental health functioning, moderate pain-related disability, and mild levels of depressive symptoms, sleep disturbances, and pain catastrophizing. Those who identified pain as an initial symptom of Marfan syndrome and those who reported that pain had spread from its initial site reported greater psychological burden compared with those without pain as an initial symptom or pain spreading. Physical health is the largest predictor of pain severity and pain-related disability. While pain catastrophizing and worse mental health functioning are significant correlates of pain severity and pain-related disability, respectively. Pain is a significant and persistent problem in Marfan syndrome and is associated with profound disability and psychological burden. Further studies are indicated to better characterize the directionality of pain, pain-related disability, and psychological burden in Marfan syndrome. © 2016 Wiley Periodicals, Inc.

Abstract
PURPOSE To describe the long-term incidence of retinal detachment, intra- and postoperative complications, and visual and refractive outcomes of children with Marfan syndrome following lensectomy for ectopia lentis, with or without subsequent correction of aphakia using the Artisan aphakic iris-fixated anterior chamber intraocular lens. METHODS The medical records of children treated at the Department of Ophthalmology, Children's University Hospital, Dublin, Ireland, from January 1, 1991, to December 31, 2011, were retrospectively reviewed. The primary outcome measure was rate of retinal detachment at final follow-up. Secondary outcomes included postoperative complications, endothelial cell count, visual acuity, refractive error, and postoperative refraction prediction error. RESULTS A total of 30 eyes of 15 patients underwent lensectomy. Of these, 16 eyes of 8 patients subsequently underwent Artisan implantation. Mean follow-up was 13.8 ± 5.9 years after lensectomy and 4.1 ± 2.8 years after Artisan implantation. There were no cases of retinal detachment. Best-corrected visual acuity was 0.11 ± 0.14 (logMAR) post-lensectomy and 0.12 ± 0.19 post-Artisan implantation. Endothelial cell count of the pseudophakic group was 3109 ± 458 preoperatively and 2632 ± 592 postoperatively. Mean cell loss was 15.4%. One eye required repeat surgical peripheral iridectomy for pseudophakic pupillary block. One eye required re-enclavation of a dislocated Artisan IOL haptic; the same eye required anterior vitrectomy for removal of retained lens fragment from the original lensectomy. CONCLUSIONS In this study cohort, there was no increased incidence of retinal detachment in children with Marfan syndrome and ectopia lentis in the setting of one or more prior intraocular procedures. A moderate rate of endothelial cell loss was observed.

Abstract
Patients with Marfan syndrome used to succumb early in life from cardiovascular complications. With the current rapid advance in medical and surgical care, such patients may now have near-normal longevities. Consequently, rare late-life complications are emerging in these patients and represent challenges to clinicians for their diagnoses and treatments. The authors report a rare case of pelvic pain and genital prolapse from a giant presacral Tarlov cyst in a 67-year-old patient with Marfan syndrome.
This 67-year-old Caucasian female presented with progressively severe pelvic pain, intermittent explosive diarrhea, and dysuria. Physical and bimanual examination demonstrated genital prolapse and a nontender, cyst-like mass fixed in the midline. She underwent ultrasound, CT, and eventually MRI evaluations that led to the diagnosis of a giant (6.7 × 6.4 × 6.6 cm) Tarlov cyst originating from the right S-2 nerve root sleeve/sacral foramen with intrapelvic extension. She underwent S1–S2 and S2–S3 laminectomy with obliteration of the Tarlov cyst using aneurysm clips. Postoperatively, her pelvic pain and bowel symptoms resolved and the bladder symptoms improved. The 3-month follow-up CT of abdomen/pelvis demonstrated resolution of the cyst.
The present case illustrates that clinicians caring for elderly patients with Marfan syndrome need to increasingly recognize such unusual late-life complications. Also, these large Tarlov cysts can be simply and effectively obliterated with aneurysm clips.

Abstract
The purpose of this study was to explore the literature on the psychosocial aspects of Marfan syndrome (MFS), to critically appraise and to synthesize relevant literature. A mixed-method systematic review was performed by searching the published literature databases using available medical, psychological, pedagogical and social databases and other sources. All studies that addressed psychosocial aspects of MFS, published in peer-reviewed journals were assessed. Of 81 search results, 15 articles (four articles based on same study population) satisfied the eligibility criteria. All studies were cross-sectional; no intervention or randomized controlled trial (RCT) studies were found. Most studies were of small sample sizes, had low response rate or participants without a verified diagnosis. Despite these limitations, all studies described, that MFS has a significant impact on the psychosocial aspects of people's lives: Decreased quality of life; challenges in education, work and family life, depression and anxiety. Some studies indicated that the subjective perception of discomfort did not necessarily match the medical severity of a disease. The research of the psychosocial aspects of MFS is limited in size and quality. More research is needed on the psychosocial aspects of MFS in samples with a verified diagnosis to develop evidence-based knowledge and appropriate guidelines.

Abstract
Marfan syndrome (MFS) is a connective tissue disorder with autosomal dominant inheritance. Advances in medicine and surgery have increased the average lifespan of classically affected patients. Serious visual and/or musculoskeletal impairment often has detrimental effects on day-to-day activities and quality of life. MFS patients suffer from many problems at younger ages and with higher frequencies than the general population because of the degenerative nature of the genetic condition. In classical MFS, changes are caused by mutations in the fibrillin-1 gene (FBN1). Mutations in the fibrillin-2 gene were discovered in individuals with a phenotypically related disorder, congenital contractural arachnodactyly. Some of the clinical manifestations of MFS cannot be explained by mechanical properties alone. Recently, mutations in the genes required for transforming growth factor-beta signaling (TGFBR1 and TGFBR2) have been found in several disorders with varying degrees of overlap with classical MFS, including Loeys-Dietz syndrome and familial thoracic aortic aneurysms and dissections. MFS is a disorder that is variable in its phenotypic expression. Specific information about mutations in the large FBN1 gene will give rise to more information about the phenotype-genotype correlations. Possible molecular mechanisms for the pathogenesis of MFS will be discussed which may assist healthcare professionals to control environmental factors that provoke individual complications in MFS.

Abstract
Marfan syndrome is a inherited connective tissue disorder due to mutations in fibrillin-1. It presents with cardiovascular, ocular, skeletal, pulmonary and dural signs and symptoms. Some of the symptoms of later onset are those associated with scoliosis and dural ectasia. This is the enlargement of the neural canal especially in the lower lumbar and sacral region and occurs in over 90% of Marfan patients. We here report three patients with lumbar and/or sacral radiculopathy due to (kypho)scoliosis and dural ectasia with spinal meningeal cysts. The pain, muscle weakness, muscle atrophy, and sensory disturbances illustrate the severe neurological complications which may occur in Marfan syndrome, especially at later age. Awareness of these complications and development of management protocols is essential since life expectancy of Marfan patients has increased. Marfan syndrome might gradually become recognized as an inherited connective tissue disorder with potentially severe neurological complications during ageing.

Abstract
The prevalence of each single feature in the Ghent criteria in patients with Marfan syndrome (MFS) is not known. To elucidate this, a cross-sectional study of 105 adults with presumed MFS was carried out. All patients were examined by the same group of investigators with standardized and complete assessment of all features in the Ghent criteria. Eighty-seven (83%) fulfilled the criteria in 56 different variants. The most prevalent major criterion in Ghent-positive persons was dural ectasia (91%), followed by major genetic criterion (89%) and ectopic lenses (62 %). In 14 persons (16%), the diagnosis was dependent on the dural findings. In all, 79% fulfilled both major dural and major genetic (positive family history and/or FBN1 mutation) criteria, suggesting that most patients with MFS might be identified by investigating these criteria. A history or finding of ascending aortic disease was present in 46 patients (53%). This low prevalence might partly reflect a high number of diagnosed patients encompassing the whole spectrum of the syndrome. The study confirms the need to examine for the complete set of features in the Ghent criteria to identify all patients with MFS. The majority of persons with MFS might be identified by the combined assessment of dura mater and family history, supplemented with DNA analysis in family-negative cases. The low prevalence of ascending aortic disease might indicate better future prospects in an adult population than those traditionally considered.

Abstract
Congenital and adult-onset inherited myopathies represent a wide spectrum of syndromes. Classification is based upon clinical features and biochemical and genetic defects. Joint hypermobility is one of the distinctive clinical features that has often been underrecognized so far. We therefore present an overview of myopathies associated with joint hypermobility: Ullrich congenital muscular dystrophy, Bethlem myopathy, congenital muscular dystrophy with joint hyperlaxity, multi-minicore disease, central core disease, and limb girdle muscular dystrophy 2E with joint hyperlaxity and contractures. We shortly discuss a second group of disorders characterised by both muscular features and joint hypermobility: the inherited disorders of connective tissue Ehlers-Danlos syndrome and Marfan syndrome. Furthermore, we will briefly discuss the extent and pattern of joint hypermobility in these myopathies and connective tissue disorders and propose two grading scales commonly used to score the severity of joint hypermobility. We will conclude focusing on the various molecules involved in these disorders and on their role and interactions in muscle and tendon, with a view to further elucidate the pathophysiology of combined hypermobility and myopathy. Hopefully, this review will contribute to enhanced recognition of joint hypermobility and thus be of aid in differential diagnosis.
