Exposure to methotrexate in utero can result in fetal methotrexate syndrome - a condition characterised by prenatal-onset growth retardation, craniosynostosis, dysmorphic facies and multiple limb abnormalities. A literature review was prompted by the findings in a girl who is presented here with full consent from her guardian. She is the third child of unrelated parents and was 4 years old at the time of this report. Her mother took 15 mg methotrexate on two occasions during early pregnancy for juvenile idiopathic arthritis, unaware that she was pregnant...

We discuss the imaging of several juvenile inflammatory arthropathies including juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile scleroderma, juvenile dermatomyositis, and chronic recurrent multifocal osteomyelitis. Juvenile idiopathic arthritis is the most common autoimmune chronic systemic disease of connective tissue in children. The remaining systemic juvenile connective tissue diseases are rare. However, they require early diagnosis and initiation of treatment to prevent injury, not only to the musculoskeletal system but also to the internal organs, and even death...

Both the fields of rheumatology and radiology are changing rapidly. Effective medication has become available for rheumatoid arthritis (RA) and transformed it from a progressive disabling disease into a chronic disease. Indications for magnetic resonance imaging (MRI) have changed accordingly, shifting toward early detection. There is also an overall increased clinical demand for high-end imaging. Together with improvement of MRI units and sequences, MRI protocols are adapted based on clinical indications. This article addresses (1) the clinical background and present role of MRI in early disease detection, (2) RA involvement of peripheral joints, (3) RA involvement of the spine, and (4) state-of-the-art RA MRI protocols...

Rheumatoid arthritis is the most commonly diagnosed systemic inflammatory arthritis, with a lifetime prevalence of up to 1% worldwide. Women, smokers, and those with a family history of the disease are most often affected. Rheumatoid arthritis should be considered if there is at least one joint with definite swelling that is not better explained by another disease. In a patient with inflammatory arthritis, the presence of a rheumatoid factor and/or anti-citrullinated protein antibody, elevated C-reactive protein level, or elevated erythrocyte sedimentation rate is consistent with a diagnosis of rheumatoid arthritis...

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic, autoimmune and degenerative joint disease leading to disability, reduced life quality, and increased mortality. Although several synthetic and biological disease modifying anti-rheumatic drugs (DMARDs) are available, there is still a medical need for novel drugs controlling disease progression. As only 10% of RA drug candidates that enter phase I trials are eventually FDA registered, there is an immediate requirement for translational drug development tools to facilitate early drug development decision making...

INTRODUCTION: Rheumatoid arthritis (RA) represents the most commonly occurring inflammatory type of arthritis and is a major cause of disability. Reports have placed emphasis on the potential of, granzyme B (GZMB) as a potentially valuable prognostic marker in early RA, the mechanism of which still remains largely unclear. Thus, the aim of the current study was to investigate the effects GZMB gene silencing influences synovial tissue hyperplasia and articular cartilage tissue injury of RA through the regulation of the MAPK signaling pathway...

Osteoarthritis (OA) is a common debilitating disease characterized by abnormal remodeling of the cartilage and bone of the articular joint. Ameliorating therapeutics are lacking due to limited understanding of the molecular pathways affecting disease initiation and progression. Notably, although a link between inflammation and overt OA is well established, the role of inflammation as a driver of disease occurrence is highly disputed. We analyzed a family with dominant inheritance of early-onset OA and found that affected individuals harbored a rare variant allele encoding a significant amino acid change (p...

Achieving fracture union is highly dependent on the initial inflammatory phase of fracture healing, which is influenced by both the local and systemic inflammatory environments. The rapidly emerging field of osteoimmunology involves the study of the interactions between the immune system and the skeletal system. Recent research has advanced the current state of knowledge regarding the effects of the surrounding soft-tissue injury, fracture hematoma, and the method of fracture fixation on the inflammatory phase of fracture healing...

Secondary renal amyloidosis (RA) is the most common type of renal involvement in ankylosing spondylitis (AS). We assessed the epidemiologic and clinico-biological profile of AS patients with RA, to analyze treatment modalities and prognostic aspects, and to determine predictive factors of RA during AS. This was a retrospective study including 13 cases of RA among 212 cases who presented with AS, during the period from 1978 to 2006. The median age of the patients at the time of diagnosing AS was 47 years (range: 19-67)...

REVIEW
Ingrid E Lundberg, Marianne de Visser, Victoria P Werth
The idiopathic inflammatory myopathies (IIMs; also known as myositis) are a heterogeneous group of disorders in which a common feature is chronic inflammation of skeletal muscle, leading to muscle weakness. Other organs are frequently affected in IIMs, such as the skin, joints, lungs, gastrointestinal tract and heart, contributing to morbidity and mortality. Currently, IIMs are most often subclassified into polymyositis, dermatomyositis and inclusion body myositis, but this subclassification has limitations as these subgroups often have overlapping clinical and histopathological features, and outcomes vary within the subgroups; additionally, subgroups without considerable myopathy are not included...

The consequences of oxidative stress and inflammation are implicated in a wide range of diseases, including rheumatoid arthritis and Parkinson's disease. The status of antioxidant capacity in rheumatoid arthritis and Parkinson's disease remains unclear, in part due to common practice of assaying erythrocytes separately to plasma. This method removes any synergistic interactions between plasma and erythrocyte-based antioxidants. The experiments in this report tested antioxidant capacity in whole blood, erythrocytes and plasma by group and disease stage...

BACKGROUND: The relationship between mental health and outcomes of unicompartmental knee arthroplasty (UKA) remains unclear. Poor preoperative mental health may be caused by pain and functional limitations associated with knee arthritis. We aimed at (1) investigating the effect of preoperative mental health on early outcomes and (2) assessing whether mental health improves after UKA. METHODS: Prospectively collected registry data of 1473 medial UKAs performed at a single institution in 2007-2014 were reviewed...

Bone and joint infections include septic arthritis, prosthetic joint infections, osteomyelitis, spinal infections (discitis, vertebral osteomyelitis and epidural abscess) and diabetic foot osteomyelitis. All of these may present through the acute medical take. This article discusses the pathogenesis of infection and highlights the importance of taking a careful history and fully examining the patient. It also emphasises the importance of early surgical intervention in many cases. Consideration of alternative diagnoses, appropriate imaging and high-quality microbiological sampling is important to allow appropriate and targeted antimicrobial therapy...

Many systemic diseases or conditions can affect the maxillofacial bones; however, they are often overlooked or incidentally found at routine brain or head and neck imaging performed for other reasons. Early identification of some conditions may significantly affect patient care and alter outcomes. Early recognition of nonneoplastic hematologic disorders, such as thalassemia and sickle cell disease, may help initiate earlier treatment and prevent serious complications. The management of neoplastic diseases such as lymphoma, leukemia, or Langerhans cell histiocytosis may be different if diagnosed early, and metastases to the maxillofacial bones may be the first manifestation of an otherwise occult neoplasm...
