Dactylitis is considered a hallmark feature of psoriatic arthritis (PsA), but it is found in other spondyloarthropathies, especially reactive arthritis, and other conditions (eg, sarcoidosis, gout, sickle cell disease, and a variety of infections). Dactylitis is difficult to define and assess with any level of consensus and consistency in PsA. A new objective measure has been developed to make assessment more uniform for clinical trials. The underlying pathophysiology has also been difficult to determine in spondyloarthropathy: synovitis, tenosynovitis, and enthesitis have all been recognized. The pathophysiology in other conditions varies but usually involves soft tissue and sometimes involves bone or joint. In non-spondyloarthropathies,treatment is determined by the underlying cause. Research on dactylitis treatment in PsA suffers from a paucity of trials and inconsistent outcome measurement. The only drug with good evidence of benefit from randomized controlled trials thus far is infliximab.

Sickle cell anaemia coexisting with gout is a rare clinical association, as is gout and eosinophilia. This report records the second case of chronic tophaceous deposits in Sickle cell anaemia. The patient also had eosinophilia in association with gout. Skeletal fluorosis was an incidental finding in this patient. Treatment with packed cell transfusions, hydroxyurea and colchicine lead to the resolution of anaemia and symptoms of acute gout.

The haemoglobinopathies are a relatively common, heterogeneous group of inherited conditions that are the result of either a quantitative abnormality (e.g. thalassaemia) or structural [e.g. sickle cell anaemia (SCA)] of the globin part of the haemoglobin molecule. Musculoskeletal (MSK) complications are common in patients with haemoglobinopathies and may affect the whole of the MSK system, in addition to bone, which is the primary site of the disease. Typical MSK complications include painful vaso-occlusive disease and osteomyelitis in SCA and reduced BMD in thalassaemia. Patients may also develop a number of related (e.g. gout) or unrelated rheumatic diseases (e.g. inflammatory arthritis and autoimmune CTDs). Treatment of MSK conditions in patients with haemoglobinopathies may be challenging (e.g. bone marrow suppression from disease-modifying agents) and in particular in SCA, steroid therapy (by any route) may precipitate potentially severe vaso-occlusive complications. Rheumatologists need to be aware of the range of MSK complications, treatment challenges and the need for such patients to be managed as part of a dedicated multidisciplinary team alongside haematology.

Surface defects have a central position in diagnosis of articular pathology. Recognizing the limitations of standard radiologic techniques and those imposed by positioning and averaging artifacts on CT evaluation, direct visualization of surface defects was pursued to identify disease characteristics that would facilitate interpretation of radiologic findings. Epi-illumination surface microscopy was utilized to examine macroscopically recognized articular surface defects in individuals in the Hamann-Todd, Terry, and Huntington human skeletal collections with previously verified diagnoses of rheumatoid arthritis, spondyloarthropathy, juvenile inflammatory arthritis (JIA), calcium pyrophosphate deposition disease (CPPD), gout, metastatic cancer, multiple myeloma, septic arthritis, tuberculosis, fungal arthritis, histiocytosis and sickle cell anemia (Rothschild and Rothschild Clin Infect Dis 20(5):1402-1408, 1995; Rothschild et al. Amer J Phys Anthropol 82(4):441-449, 1990; Rothschild and Rothschild Amer J Phys Anthropol 96(4):357-563, 1995; Rothschild and Woods Clin Exp Rheumatol 10(2):117-122, 1992; Barrett and Keat Radiographics 24(6):1679-1691, 2004; Rothschild and Heathcote Amer J Phys Anthropol 98(4):519-525, 1995; Rothschild and Woods Am J Phys Anthropol 85:25-34, 1991; Hershkovitz et al. Amer J Phys Anthropol 106(1):47-60, 1998; Winland et al. Amer J Phys Anthropol 24:S243, 1997; Rothschild et al. Clin Exp Rheumatol 10(6):557-564, 1992; Rothschild and Martin , 2006; Rothschild et al. Amer J Phys Anthropol 102(2):249-264, 1997). Observed alterations were compared with standard radiographs. Fronts of resorption distinguished inflammatory arthritis from those caused by the other disorders studied. Multiple myeloma, fungal disease, and gout are expansile character; the latter accompanied by reactive new bone formation more prominent than that noted with spondyloarthropathy and JIA. Those were clearly distinguished from the crumbling alterations found with CPPD. Histiocytosis had a unique crenulated appearance, while nodules were prominent with syphilis. Defects in sickle cell anemia had ivory fragments at their base. These findings provided explanation for radiologic observations. Direct surface microscopy revealed characteristics apparently pathognomonic for specific disorders and facilitated distinguishing among them. The technique provides visualization an order of magnitude greater than that available with clinical radiologic techniques and identifies new characteristics which should facilitate clinical diagnoses. This demonstrates that there would be value to the development of higher resolution, clinically applicable imaging techniques.

The rise in non-communicable diseases in Africa presents challenges for health systems that are burdened by infectious diseases. Gout is one of those diseases that has seen an increase in numbers worldwide, including Africa. Gout is commonly associated with comorbidities and mortality. It directly impacts the quality of life, increases health costs, decreases physical function, and significantly increases the time from work, much of which is potentially avoided if treatment is instituted early. Despite advances in understanding the pathophysiology and outcomes of gout, the quality of care delivered to patients in Africa is still suboptimal. Existing data on gout in Africa reveals a general low index of suspicion due to limited knowledge of the disease by healthcare workers resulting in late diagnosis, with severe polyarticular tophaceous gout being a common presenting feature. These late presentations are associated with avoidable disability and increase the direct and indirect costs of managing gout. The challenges are related to lack of government budgetary support for staff training, infrastructure for diagnosis, and availing medicines. The picture of gout in Africa largely mirrors the west concerning risk factors, comorbidities, and burden of disease, but with some unique presentations seen in HIV, sickle cell disease, and vertigo. We discuss the challenges of gout diagnosis and management in Africa and propose a roadmap to improve gout outcomes across Africa.
