A 76-year-old male patient who has been suffering from psoriatic arthritis (PsA) for 15 years was diagnosed with chronic lymphocytic leukemia (CLL) 18 months ago. He has been treated him with a Bruton’s tyrosine kinase (BTK) inhibitor (ibrutinib) at a dose of 420 mg once daily (q.d.) for his CLL. For about two years, he received a quite successful treatment with methotrexate and the subcutaneously administered tumor necrosis factor (TNF) inhibitor (adalimumab) for his PsA, until his plaque psoriasis worsened. He consulted us when the severity of his skin condition necessitated a change in his treatment regimen. In the following discussion, we explore treatment options for this clinical scenario, with a particular focus on managing PsA in the context of CLL as a comorbidity. Additionally, we report on the initial phase of treatment with an anti-interleukin-23 (IL-23) inhibitor (guselkumab), specifically targeting his aggravated psoriasis.

The COVID-19 pandemic changed healthcare practices and social media played a significant role in those changes. While social media and online practice communities allow collaboration and engagement, education and knowledge dissemination, research and publication, promotion, and the potential for improved clinical care, their use also involves perils and pitfalls. The literature suggests that rheumatologists use innovative social media platforms for both professional and social purposes. Similarly, many patients with rheumatic disease use social media for education and communication. This review outlined the background of social media platforms, the reasons for their use, and associated risks. This review further discussed the need to better understand the benefits of social media and online communities as well as the potential negative effects that could impact the practice of rheumatology.

Co-prescription of anti-inflammatory prophylaxis with colchicine, non-steroidal anti-inflammatory drugs (NSAIDs), or corticosteroids when initiating urate-lowering therapy (ULT) for gout is recommended in clinical guidelines to prevent ULT-induced flares and optimise adherence to ULT. Colchicine prophylaxis is highly clinically and cost-effective and there has been great interest recently in its cardioprotective effects. However, one in four people initiating ULT without prophylaxis in randomised trials do not have a gout flare within six months of initiation, raising the question of whether all people initiating ULT for gout should receive prophylaxis. Uptake of prophylaxis varies and appears to be common in secondary care settings but less commonly used in primary care, where most people with gout are managed and gout may be less severe. Recent clinical guidelines have highlighted that the patient’s perspective is important and that the pros and cons of prophylaxis should be discussed with people with gout initiating ULT. Uptake of prophylaxis seems likely to be influenced by perception of an individual’s risk of ULT-induced flares, as well as concerns about adverse events, polypharmacy, drug interactions, and cost. We advocate a personalised approach between people with gout and clinicians to reach shared treatment decisions when considering co-prescription of prophylaxis when initiating ULT, empowering people with gout to make decisions about their care.

Musculoskeletal ultrasound has become a valuable imaging tool in the diagnosis and management of rheumatologic disorders. Expertise in recognizing sonographic findings of pathology is the basis for its successful application in clinical use. This article will provide descriptions and a pictorial essay of ultrasound findings in common musculoskeletal manifestations of rheumatologic disorders.

Chronic pain is a common problem in rheumatology. A distinction is made between nociceptive pain and nociplastic pain. Nociceptive pain is, for example, mechanistically explained by persistent inflammation. Neuropathic pain is caused by nerve damage of various possible causes. In contrast, nociplastic pain is not due to tissue damage or a lesion in the somatosensory nervous system—at least not with the currently available techniques. Nociplastic pain is based on an altered perception of pain through modulation of stimulus processing. The concept of central sensitization, together with other neurobiological and psychosocial mechanisms, is considered to be the best explanation for such pain conditions. The syndrome of fibromyalgia (FM), considered to be due to central sensitization, plays a major role in rheumatology—both in terms of differential diagnosis and because the management of inflammatory rheumatic diseases can be made more difficult by the simultaneous presence of FM. During the coronavirus pandemic, persistent pain syndromes with similarities to FM were described following a COVID-19 infection. There is a growing scientific controversy as to whether the so-called long COVID syndrome (LCS) is a separate entity or just a variant of FM.

Screening for developmental dysplasia of the hip (DDH) in Greece is being performed according to the guidelines issued by the Institute of Child Health in 2015. Screening strategies include universal clinical screening and selective (based on clinical findings or risk factors) sonographic screening. Clinical examination is performed by neonatologists and paediatricians and findings are recorded in the baby’s Health-Book. Whenever clinical examination is suspicious (however non-specific), children are referred for an ultrasound scan and/or to a (paediatric) orthopaedic surgeon. In the case of a positive clinical examination, children are referred to a (paediatric) orthopaedic surgeon, who treats them, when needed. All types of abduction devices are used for treatment (Pavlik, Tubingen), as well as plaster cast, which is preferred in older babies. There are no official guidelines over the selection of the sonographic method for screening; however, the mostly used technique is Graf’s, according to publications from Greek centers. Training of operators on the sonographic examination technique is carried out during radiology residency, depending on hospital availability/expertise, through seminars with hands-on workshops and/or during fellowships. Radiologists and certified paediatric orthopaedic surgeons are the only ones legally allowed to perform neonatal/infantile hip sonography in Greece. Emphasis on the benefits of universal screening and standardized techniques are increasingly taught and repeated, which may eventually influence the decision-making process and standardize the performance of hip sonography within the next few years.

Calcium pyrophosphate deposition (CPPD) disease is the most prevalent crystal related arthropathy in the older-aged population. The clinical spectrum of CPPD arthropathy can include asymptomatic, acute, and chronic inflammatory disease that primarily results in irreversible structural joint damage. The manifestations and impact of structural damage that result from other inflammatory non-degenerative features of chronic CPP crystal inflammatory arthritis are often underrecognized and may lead to an inaccurate perception of disease severity. This pictorial essay sought to display the disease burden and various presentations of chronic inflammatory CPP crystal arthritis. Sonographic imaging of cases with chronic CPP arthritis was presented for diagnostic considerations and to demonstrate the extent of irreversible articular and peri-articular damage occurring at a structural level. Evolving understanding of the imaging characteristics of CPPD disease will provide a better appreciation of disease morbidity caused by this condition and stress the need to expand efforts to find effective treatments to dissolve crystal deposition and targeted therapies that will contain the inflammatory response to crystals. Recognizing the anatomic consequences of tissue damage that arise from CPPD disease should also help reflect on potential surgical alternatives to mitigate the progression of structural complications until effective disease modifying agents for this condition emerge.

The diagnosis of hip dysplasia has developed very differently in different countries over the last few decades. The development and current situation in Hungary is described in this paper. The Ortolani test is still the gold standard for clinical examination in most regions. Hip sonography is not officially established and is only used occasionally. However, thanks to private initiatives, more and more orthopaedic surgeons are now familiarising themselves with this method and the first courses are being held in accordance with International Interdisciplinary Consensus Committee on DDH Evaluation (ICODE) guidelines. A regional screening with Graf hip sonography was carried out in Szeged. The results of the evaluation impressively demonstrate the efficiency of this method.

The diagnosis of hip dysplasia has developed very differently in different countries over the last few decades. The development and current situation in Switzerland is described in this paper. In the meantime, early diagnosis by means of Graf hip sonography, corresponding to screening, has been established, although it varies from region to region. The training system for examiners is also clearly regulated. The massive reduction in costly treatments and operations documents the success of the efforts made in Switzerland.

Calcium pyrophosphate deposition disease is known as crowned dens syndrome or peripheral arthritis, especially of knees, hips and shoulders. The disease course is asymptomatic, with acute or chronic disease activity related to osteoarthritis, especially in the elderly. Other risk factors are joint injury, osteoarthritis and metabolic conditions such as primary hyperparathyroidism, hemochromatosis, hypophosphatasia and hypomagnesemia. Genetic background should be considered before the age of 55 years. Only recently was the value of signs and symptoms weighted, allowing the introduction of classification criteria. Biomarkers include compensated polarized light microscopy findings, laboratory values and imaging. Imaging evidence refers to calcification of the fibrocartilage or hyaline cartilage. Chondrocalcinosis defined as such cartilage calcification is most commonly due to calcium pyrophosphate deposition disease. Calcification of the synovial membrane, joint capsule, or tendon should not be scored. Ultrasonography detects calcium pyrophosphate deposits with more than 80% sensitivity rates, which is superior to conventional radiography. In the future, dual-energy computerized tomography and Raman spectroscopy are promising new techniques to assess disease activity. Currently, the primary therapeutic goal is controlling inflammatory reactions and preventing further episodes. However, only hydroxychloroquine and magnesium carbonate have shown some efficacy and reduction of pain intensity so far. As patients report more significant unmet treatment needs than patients with gout, education is an essential issue of care. The new classification criteria will allow the validation of standardized outcome parameters with the definition of remission and low disease activity for developing treat-to-target strategies to perform well-designed interventional trials evaluating new treatment options and strategies.
