Abstract
PURPOSE Outcomes after total knee arthroplasty (TKA) for patients with systemic sclerosis (SSc) are poorly documented in the literature. The purpose of this study was to evaluate SSc as a potential risk factor for increased rate of complications after TKA. METHODS Using the PearlDiver Mariner database, 2,002 patients with SSc undergoing primary TKA were identified and compared to matched controls of 19,892 patients without SSc. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to two years. 90-day ED-visit and inpatient readmission were also documented. RESULTS Compared to the matched controls, patients with SSc demonstrated higher rates of medical complications such as cerebrovascular accident (1.5% vs 0.6%, p < 0.001), myocardial infarction (1.3% vs 0.3%, p < 0.001), and sepsis (1.1% vs 0.4%, p < 0.001). Additionally, patients with SSc displayed elevated rates of surgical complications, including wound complications (3.9% vs 2.2%, p < 0.001) and aseptic loosening at 90 days (0.2% vs 0.1%; OR 3.53 [1.13-9.28]), one year (0.7% vs 0.4%; OR 1.78 [0.96-3.05]), and two years (1.4% vs 0.9%; OR 1.68 [1.10-2.45]). Patients with SSc also had higher rates of emergency department visits (21.2% vs 11.4%, p < 0.001). CONCLUSIONS Patients with SSc are at higher risks of postoperative complications, encompassing both medical and surgical complications. Specifically, patients with SSc have a significantly higher likelihood of experiencing wound complications, cerebrovascular accident, and myocardial infarction. It is crucial for orthopaedic surgeons and patients alike to consider the elevated risks when determining a course of TKA for patients with SSc.

Abstract
Introduction:
Scleroderma is a rare heterogeneous multisystem autoimmune disease. The disease is characterized by structural abnormalities of the small blood vessels. Scleroderma affects all organs of the body. Skin manifestations are commonly reported, but peripheral nervous system (PNS) and central nervous system (CNS) involvement has been less frequently reported. Neurological manifestations are broad, and it is challenging for clinicians to confirm a diagnosis of scleroderma.
Case Presentation:
In our case, a 53-year-old white woman had extensive clinical presentations: skin rashes and symptoms from internal organs, CNS, and PNS during the previous 11 years. She had not undergone any specific treatment because diagnosis has not been made in the early stages.
Conclusion:
It is important to make the diagnosis as early as possible and start treatment with immunomodulatory and immunosuppressant medication, as it affects the patient's disease progression, quality of life, and mortality. A detailed medical history, physical examination, and laboratory and radiology findings help us to identify and diagnose scleroderma. But unfortunately, it was late, and the patient died. This case guides us to be more careful and make the diagnosis of scleroderma earlier in the future.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a rare chronic multi-system autoimmune disease of unknown cause and a complex pathogenesis. The hallmark of the disease is microvascular vasculopathy which results in tissue ischemia with recurrent episodes of reperfusion. Diffusion-weighted (DW) Magnetic Resonance imaging (MRI) is an excellent tool for the detection of activity of any vascular or inflammatory lesions. OBJECTIVES Detect brain changes in systemic sclerosis patients with asymptomatic CNS manifestations using fluid attenuation inversion recovery (FLAIR) weighted sequence and diffusion-weighted (DW) sequence MRI. METHODS Fifteen systemic sclerosis female patients aged 27-60 years old with disease duration of 1-20 years with no CNS clinical manifestations were included. A controlled group of 14 clinically normal persons, age and sex matched. Both groups were subjected to brain MR examination at 1.5T; a FLAIR weighted sequence and a DW sequence. SPSS (version 20) was used for statistical analysis. RESULTS 37 white matter hyperintense lesions (≤2 to ≥ 5mm in diameter) were detected in patient group using FLAIR weighted MRI while diffusion-weighted MRI failed to detect the same lesions. A non-significant relation (P=.259) between the presence of white matter hyperintense lesions and the severity of peripheral vascular affection of the disease was observed. CONCLUSIONS Asymptomatic central nervous system vasculopathy is detected in systemic sclerosis using FLAIR MRI, while diffusion MRI failed to detect such lesions. These findings suggest a non-inflammatory form of central nervous system microvasculopathy in SSc patients.

Abstract
Systemic sclerosis is a chronic autoimmune disease of still not fully understood pathogenesis. Fibrosis, vascular wall damage, and disturbances of innate and acquired immune responses with autoantibody production are prominent features. Systemic sclerosis has specific subsets with different autoantibodies, and differences in the affected skin areas. The suspicion of systemic sclerosis and establishing the diagnosis will be facilitated by the criteria created by EULAR/ACR experts. The treatment of this autoimmune disease remains a challenge for clinicians and new therapeutic options are constantly sought. The occurrence of various symptoms and the involvement of many organs and systems make systemic sclerosis a multidisciplinary disease and require a holistic approach. The present article summarizes different clinical features of systemic sclerosis and the profile of autoantibodies and discusses recent rules and future perspectives in disease management.

Abstract
Background/objectives Systemic sclerosis (SSc) is an autoimmune disease associated with immune abnormalities and widespread vascular lesions, including increased intimal and medial thickness. These changes may be reflected in early atherosclerosis and cardiovascular risks. We aimed in this study to examine the carotid artery intima-media thickness and MRI brain findings in SSc patients and compared them to a group of normal controls. A relationship between these parameters and clinical measures in SSc was also sought. Methods Seventy-two SSc patients with no central nervous system (CNS) symptoms and 42 healthy controls were included. Clinical and laboratory measures, Medsger’s severity scale, and Doppler ultrasound common carotid artery intima-media thickness (CCA-IMT) were measured. Brain fluid-attenuated inversion recovery (FLAIR)-MRI and diffusion-weighted MRI (DWI) were also done. Results SSc patients had more CCA-IMT, higher CRP, and more brain MRI hyperintense lesions than controls (P < 0.05). Significant positive correlations existed between CCA-IMT and Medsger vascular (r = 0.7, P = 0.02). The FLAIR-MRI showed multiple hyperintense lesions in 24 patients (33%), ranging 0–36 lesions. SSc patients with more lesions (positive MRI) had longer disease duration (P = 0.001) and left and right carotid artery atheromata (P = 0.001, and 0.013, respectively) than SSc patients with negative MRIs; Medsger vascular score did not separate the SSc groups (P = 0.08). Conclusions In systemic sclerosis patients without central nervous system symptoms, MRI lesion numbers correlated with CCA-IMT. MRI abnormalities were found more frequently if CRP was elevated, if the Medsger SSc Severity Scale was increased, or if there was thickened carotid IMT.

Abstract
Background: The scleroderma is a complex autoimmune collagen disorder that can affect many organs simultaneously, as it occurs in the systemic sclerosis (SS), or only the skin, as it occurs in the localized scleroderma (LS). The neurological presentation is extremely uncommon, and even more uncommon are the symptoms of the scleroderma in the cerebellum. Case Description: We report the case of a 56-year-old male with cerebellar lesions mimicking a brain abscess. After surgical excision, the histopathological diagnosis deposed for an ischemic necrosis caused by a vasculopathy. All the bacteriological and viral exams were negative, whereas the rheumatologic tests were compatible with the scleroderma pattern. Conclusion: Up to now, the literature has described only 5 cases of scleroderma in the posterior cranial fossa. The authors report a case of SS causing colliquative necrosis in the cerebellum. Pathogenetic mechanisms, clinical aspects, and radiological features are discussed along with the pertinent literature.

Abstract
OBJECTIVES To perform a systematic review of neurologic involvement in Systemic sclerosis (SSc) and Localized Scleroderma (LS), describing clinical features, neuroimaging, and treatment. METHODS We performed a literature search in PubMed using the following MeSH terms, scleroderma, systemic sclerosis, localized scleroderma, localized scleroderma "en coup de sabre", Parry-Romberg syndrome, cognitive impairment, memory, seizures, epilepsy, headache, depression, anxiety, mood disorders, Center for Epidemiologic Studies Depression (CES-D), SF-36, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Patient Health Questionnaire-9 (PHQ-9), neuropsychiatric, psychosis, neurologic involvement, neuropathy, peripheral nerves, cranial nerves, carpal tunnel syndrome, ulnar entrapment, tarsal tunnel syndrome, mononeuropathy, polyneuropathy, radiculopathy, myelopathy, autonomic nervous system, nervous system, electroencephalography (EEG), electromyography (EMG), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). Patients with other connective tissue disease knowingly responsible for nervous system involvement were excluded from the analyses. RESULTS A total of 182 case reports/studies addressing SSc and 50 referring to LS were identified. SSc patients totalized 9506, while data on 224 LS patients were available. In LS, seizures (41.58%) and headache (18.81%) predominated. Nonetheless, descriptions of varied cranial nerve involvement and hemiparesis were made. Central nervous system involvement in SSc was characterized by headache (23.73%), seizures (13.56%) and cognitive impairment (8.47%). Depression and anxiety were frequently observed (73.15% and 23.95%, respectively). Myopathy (51.8%), trigeminal neuropathy (16.52%), peripheral sensorimotor polyneuropathy (14.25%), and carpal tunnel syndrome (6.56%) were the most frequent peripheral nervous system involvement in SSc. Autonomic neuropathy involving cardiovascular and gastrointestinal systems was regularly described. Treatment of nervous system involvement, on the other hand, varied in a case-to-case basis. However, corticosteroids and cyclophosphamide were usually prescribed in severe cases. CONCLUSIONS Previously considered a rare event, nervous system involvement in scleroderma has been increasingly recognized. Seizures and headache are the most reported features in LS en coup de sabre, while peripheral and autonomic nervous systems involvement predominate in SSc. Moreover, recently, reports have frequently documented white matter lesions in asymptomatic SSc patients, suggesting smaller branches and perforating arteries involvement.

Abstract
Scleroderma (SSc) is a rare connective tissue disease characterized by fibrosis, microvasculopathy and autoimmune features. The role of genetics is limited in SSc, as suggested by similar concordance rates in monozygotic and dizygotic twin pairs, while environmental factors may act through epigenetic changes, as demonstrated for specific genes. Further, sex chromosome changes have been reported in SSc and may explain the female preponderance. In the present study we compared the methylation profile of all X chromosome genes in peripheral blood mononuclear cells from monozygotic twins discordant (n=7) and concordant (n=1) for SSc. Methylated DNA immunoprecipitations from each discordant twin pair were hybridized to a custom-designed array included 998 sites encompassing promoters of all X chromosome genes and randomly chosen autosomal genes. Biostatistical tools identified sites with an elevated probability to be consistently hypermethylated (n=18) or hypomethylated (n=25) in affected twins. Identified genes include transcription factors (ARX, HSFX1, ZBED1, ZNF41) and surface antigens (IL1RAPL2, PGRMC1), and pathway analysis suggests their involvement in cell proliferation (PGK1, SMS, UTP14A, SSR4), apoptosis (MTM1), inflammation (ARAF) and oxidative stress (ENOX2). In conclusion, we propose that X chromosome genes with different methylation profiles in monozygotic twin pairs may constitute candidates for SSc susceptibility.
