摘要:

Alveolar echinococcosis (AE) is a rare parasitic disease caused by the larval stage ofEchinococcus multilocularis. It differs from cystic echinococcosis caused byEchinococcus granulosus. The main endemic areas of AE are Alaska, Canada, Japan, and parts of Europe. Hepatic involvement invariably occurs, but it is unusual for bone to be affected. We report the case of a woman presenting with a long history of pain, cachexia, morning stiffness, and biological signs of inflammation. Radiographs and principally magnetic resonance images were nonspecific, showing inhomogeneous osteolysis of vertebral bodies without loss of intervertebral disc height but with a paravertebral mass. The diagnosis ultimately relied on pathological examination, which showed an anhistic laminated membrane colored in red with Periodic-Acid-Schiff surrounding a central cavity, and by the serologic testing, principally ELISA Em2+ method, which allowed a 97% specificity and 99% specificity in the diagnosis of AE.AE involving bone is an uncommon condition. Although magnetic resonance imaging can be used to search for local complications, the features it detects are, like those revealed by radiographs, nonspecific and can lead to AE being misdiagnosed as neoplasm or tuberculous osteitis. When a patient presents with suspected AE in an endemic area, the diagnosis can be achieved by serological testing alone (Western blot and Em2+ ELISA), thereby avoiding the need for biopsy.

摘要:

The macrophage activation syndrome (MAS) is a rare, potentially fatal, clinical syndrome, which has been described in childhood rheumatic disorders. MAS is defined by a prolonged period of fevers, pancytopenia, and hypertriglyceridemia (with or without hypofibrinogenemia). Histopathological examination of bone marrow, spleen, or lymph nodes shows hemophagocytosis by mononuclear phagocytes. In patients with Still’s disease, observed triggering events for MAS have included both infectious processes and pharmacological agents, such as parenteral gold and nonsteroidal anti-inflammatory drugs. We report the case of a young woman with adult-onset Still’s disease (AOSD), complicated by an Epstein-Barr virus infection and subsequent MAS, whose course worsened after administration of the soluble tumor necrosis factor-&agr; receptor, etanercept. Subsequent treatment with pulse corticosteroids and cyclosporine A induced a dramatic clinical improvement. Treatment data regarding the use of etanercept in AOSD are lacking; given our experience and recent reports in children with Still’s disease, we would suggest caution using this agent in patients with AOSD, particularly when complicated by MAS.

摘要:

A 39-year-old woman with long-standing seropositive rheumatoid arthritis who had a total replacement of her left knee with a modular prosthesis in 1994 presented with fever, pruritic rash, and acute synovitis of that joint following local trauma. Synovial fluid showed a charcoal-like color, and contained abundant phagocytes laden with metal particles. In patients with rheumatoid arthritis who have undergone total joint replacement, metal particle reactions and possible hyper-sensitivity should be added to the list of potential causes of superimposed acute synovitis and systemic manifestations.

摘要:

Polymyalgia rheumatica (PMR) and temporal arteritis (TA) have been associated with a seronegative polyarthritis that can mimic rheumatoid arthritis. Sacroiliitis and osteitis pubis are most often encountered in the different types of spondyloarthropathy. However, sacroiliitis and osteitis pubis have rarely been described in patients with polymyalgia rheumatica and temporal arteritis. We present two patients, one with temporal arteritis and the other with polymyalgia rheumatica, who also had many features of a spondyloarthropathy, including sacroiliitis and osteitis pubis. In reviewing the literature, we found 30 other patients with a diagnosis of PMR who also had sacroiliitis and/or osteitis pubis. We propose that the inflammatory arthritis associated with polymyalgia rheumatica and temporal arteritis can involve the axial joints, resembling a spondyloarthropathy. It is important for the clinician to recognize that sacroiliitis and osteitis pubis have been associated with PMR and TA so that their radiographic presence does not dissuade the clinician from making the correct diagnosis.

摘要:

Capnocytophaga gingivalisis most often isolated as normal oral flora or with periodontal disease. This organism is also associated with sepsis usually in immunocompromised hosts. We identified pyogenic arthritis caused byC. gingivalisin a 3-year-old immunocompetent male, whose clinical course closely resembled monoarticular onset pauciarticular juvenile rheumatoid arthritis. This is the first report ofC. gingivalisseptic arthritis in the world literature, but there are increasing reports of infections with this carbon dioxide-loving organism at other sites in nonimmunocompromised individuals. The subacute presentation of the monoarthritis with this organism of low virulence led to a long delay in diagnosis and treatment. Any monoarthritis must continue to raise concern about infection.

摘要:

This case describes a 58-year-old female with systemic lupus erythematosus (SLE) and coexistent chronic tophaceous gout. A renal biopsy showed concurrent lupus nephritis and renal medullary microtophi, confirmed by electron and polarizing microscopy, respectively. Whereas clinical SLE and gout have already been shown to be rarely associated, this case further illustrates the presentation of these two diseases in a single renal specimen. In this patient the gout began shortly after menopause without known risk factors and before any overt renal disease or signs of SLE. The tophaceous gout antedating the SLE, as well as the apparently benign course of illness, suggest that the pathologic effects of SLE and gout on the kidneys are based on independent mechanisms and may not necessarily aggravate each other. Treatment of the gout with allopurinol may have contributed to improved renal function.
