Synovial DiseasesPigmented Villonodular Synovitis2 moreThrough the high-throughput feature extraction of magnetic resonance images, the deep learning prediction model of joint synovial lesions is constructed used for the diagnosis, differential diagnosis and curative effect monitoring of joint synovial lesions.
Fibromyalgia-like Joint/Muscle Pain and Synovitis in Non-celiac Wheat Sensitivity Patients
Non-celiac Wheat SensitivityRecently it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have CD or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'Non-Celiac Wheat Sensitivity' (NCWS), since it is not known what component of wheat causes the symptoms in NCGS patients, and the investigators also showed that these patients had a high frequency of coexistent multiple food hypersensitivity. The clinical picture of NCWS is characterized by combined gastrointestinal (bloating, abdominal pain, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and extra-intestinal and/or systemic manifestations (headache, depression, anxiety, 'foggy mind,' tiredness, dermatitis or skin rash, fibromyalgia-like joint/muscle pain, leg or arm numbness, and anemia). Nowadays no data are available on the characteristic of 'rheumatologic' symptoms of NCWS patients. Therefore, the aims of the present study are: 1) to investigate the prevalence of fibromyalgia-like joint/muscle pain in NCWS patient, 2) to search for possible ultrasonographic alterations (i.e. synovitis) of hands and feet joints of NCWS patients, and 3) to evaluate modification of fibromyalgia-like joint/muscle pain in NCWS patients after a gluten free diet period of almost 6 months.
The Use of PET/CT to Evaluate Synovitis in the Temporomandibular Joint (TMJ)
Temporomandibular JointConservative Treatment TherapyTemporomandibular joint disorders (TMD) are a common musculoskeletal problem with an estimated 40-75 percent of the population reporting at least one sign. Up to fifteen percent of the patients who seek care for one of these conditions, will go on to develop chronic pain. The two most common TMD conditions include myofascial pain disorder and internal derangement of the Temporomandibular Joint (TMJ). These two conditions have similar clinical presentations, making an accurate diagnosis difficult. Currently, there is no accurate exam or test to differentiate between these two conditions. Internal derangement of the TMJ is a condition with disk displacement, pain, and dysfunction, which may progress to localized osteoarthritis. Fortunately, this condition is self-limiting for the majority of the patients afflicted, with a small minority progressing to advanced joint destruction, disability and chronic pain.18 Currently there are no prognostic indicators to identify these individuals. There are three hypothesis of degenerative TMJ disease, they include: direct mechanical trauma, hypoxia reperfusion injuries, and neurogenic inflammation. All involve parafunctional habits such as clenching or grinding by the patient and a low-grade inflammatory response/synovitis. 18-fluorodeoxyglucose (18-FDG), a radioisotope used with positron emission tomography (PET) and paired with a CT scan (PET/CT), may have a role in imaging inflammation in arthritis as recently demonstrated in several pilot studies involving osteoarthritis of the knee and shoulder. 18-FDG accumulates in areas of increased metabolism, particularly activated leukocytes, as measured by increased standardized uptake value.2 PET/CT offers the unique advantage of showing active disease before anatomic damage is evident. Our hypothesis is that there is an increased uptake of 18-FDG on PET/CT in synovitis of the TMJ.
Comparison of the Frequency of Subclinic Synovitis in the Distal Interphalangeal Joints of the Hand...
PsoriasisSynovitisIn this cross-sectional study, it was planned to compare the frequency of subclinical synovitis in the distal interphalangeal joints of the hands in psoriasis patients. 28 patients followed up by the Dermatology Department with a diagnosis of psoriasis and referred to us and 28 healthy volunteers were included in the study. Participants' age, gender, body mass index (BMI), year of psoriasis diagnosis, treatments they received, and comorbid diseases were recorded as demographic information. Psoriasis Area and Severity Index (PASI) and Nail Psoriasis Severity Index (NAPSI) were calculated by a dermatologist. Tenderness in the distal interphalangeal joints of both hands was evaluated by palpation. Subsequently, the presence of ultrasonographic synovitis findings of the participants was examined by a physician who was experienced in musculoskeletal ultrasonography and was blind to clinical evaluations. Scoring was done with the EULAR GS / PD joint scoring system and EULAR-OMERACT composite scoring system. The scores of the most affected joint were used in statistical analysis. Comparisons were made between psoriasis and control groups in terms of scores. Relationships between variables in the psoriasis group were examined.
Screening of Specific Genes for Pigmented Villous Nodular Synovitis
Pigmented Villonodular SynovitisThis study retrospectively analyzed the history of present illness of PVNS patients in our hospital. The enrolled patients were followed up by telephone to follow up their postoperative recovery and living conditions. Take the patient's pathological specimens for immunohistochemical testing, evaluate the relationship between the expression of different molecular targets, clinical manifestations and patient prognosis, and explore new molecular targets related to disease diagnosis and treatment.
The Pathogenesis of Inflammatory Synovitis: A Study of Early Arthritis
ArthritisArthritis5 moreThis study will evaluate patients with inflammatory forms of arthritis within the first year of onset. The study will attempt to clarify factors that may predict disease course such as evolution into rheumatoid arthritis (RA) or other chronic inflammatory arthropathies. Synovial biopsies and synovial fluid will be obtained to search for microbial agents and other initiating and modulating factors that may be most readily distinguished early in the disease and to determine the stage of disease at which certain immunologic and hormonal changes become evident. The study will also search for genetic and other features that may be associated with specific forms of inflammatory arthropathies that might predict the subsequent clinical disease course or response to different agents used in treatment of RA, Reiter's syndrome and other types of chronic inflammatory arthropathies.
The Relation Between Dedicated Extremity MRI Synovitis and Structural Deterioration Radiographic...
Rheumatoid ArthritisThe major aim of treatment for rheumatoid arthritis is remission. Nevertheless, structural radiographic progression is observed in 15 to 20% of patient getting remission. Numerous definitions of the remission proposed by literature remain imperfect. Recently ultrasonography and MRI seem to be helpful in diagnosis and follow-up of rheumatoid arthritis. Studies in patients with clinical remission are reporting 75 to 90% of persistent MRI and ultrasonography synovitis, 45% of cases with synovial activity. To our knowledge, in such case few studies showed correlation between persistent imaging synovitis and structural radiographic progression. On the other hand, no studies with extremity dedicated RMI in patients with remission are reported. In this preliminary study, the investigators propose to evaluate in patients with rheumatoid arthritis remission and persistent dedicated MRI synovitis the structural radiographic progression at one year.
Prognostic Indicators and Determinants of the 2-5 Year Outcome in a Cohort of Early Synovitis Patients...
ArthritisReactive3 moreThis study will evaluate the 2-5 year outcome of a cohort of 250 patients with early synovitis, who were recruited into protocol 94-AR-0194 (The Pathogenesis of Inflammatory Synovitis: A Study of Early Arthritis). Clinical, radiographic, and functional outcome parameters, particularly those relating to articular damage and functional loss, will be evaluated and related back to clinical, serologic, immunogenetic, and pathologic variables identified at the onset of the arthropathy. A model will be generated which incorporates and weighs the variables in order to determine diagnostic and prognostic markers in the early stages of arthritis. Synovial tissue samples have been obtained from the entire cohort at the initial visit of protocol 94-AR-0194. Studies of these biopsies have so far demonstrated evidence for the presence of infectious agents in a proportion of the samples, and have generated information regarding the cytokine profiles in the early stages of synovitis. In an attempt to further define the pathogenetic mechanisms of synovitis longitudinally, biopsies will be repeated on selected subsets of the cohort. Specific questions to be answered relate to the persistence of microbial agents in the synovium, and to the evolution of cellular and molecular mechanisms which mediate the invasive, destructive potential of the synovial lesion. It is anticipated that these studies should prove valuable to clinicians who are attempting to stratify patients for therapeutic strategies, early in their disease course. They should also prove valuable in enhancing the understanding of the pathogenetic mechanisms of synovitis.
Evaluation of the Effectiveness of Surgical Treatment of Villo-nodular Synovitis of the Hip in Children...
SynovitisVillo-nodular synovitis can affect the joints, bursae or tendon sheaths. This condition is rare, with 1.8 cases per million inhabitants. The hip is affected in 3.6 to 18.1% of cases. The age of predilection is between 30 and 50 years old and this condition is rarely described in children. Two articles report a case of villous-nodular synovitis of the child's hip. Surgical treatment by resection seems to be consensus but various adjuvant treatments are also proposed. A case of villous-nodular synovitis of the hip in children was treated without surgical intervention. The main objective of this study was to evaluate the efficacy of surgical treatment of villous nodular synovitis of the hip in children.
Painless Synovitis in Patients With Longstanding Rheumatoid Arthritis
- Rheumatoid ArthritisThere is a group of patients with rheumatoid arthritis (RA) that suffer from chronically painless synovitis in the hands. The objective of this study is to compare painless synovitis with painful synovitis according to the sonographic (Gray-scale and power Doppler) findings. A sonographic examination (Gray-scale and power Doppler) will be done to evaluate metacarpophalangeal joints of patients without local painful and will be a comparison with patients with local painful.
