Epithelioid sarcoma of the right ilium mimicking sacroiliitis.

Epithelioid sarcoma represents less than 1% of soft tissue sarcomas and has a high recurrence rate and strong ability to invade the regional lymphatic pathways. Classic epithelioid sarcoma has a predilection for young men and usually affects the distal extremities, while the proximal-type is characterized by different histological features and most commonly occurs in the proximal part of the extremities, trunk and pelvis. Intraosseous tumor development is rare.

[Pyogenic arthritis caused by Streptococcus agalactiae: report of four cases and a review of the literature].

Most infections by group B streptococcus of the Lancefield classification (Streptococcus agalactiae), were reported in pregnant women or during the puerperal period, as well as in neonates. During the past three decades there have been reports of increasingly invasive infections in adults unrelated to pregnancy, although arthritis and osteomyelitis are still very rare. In this article, we describe four new adult patients with arthritis by S.

[Septic arthritis complicating neuropathic shoulder due to cervical syringomyelia].

One of the main causes of neuropathic osteoarthropathy of the shoulder is cervical syringomyelia. Chronic pain and swelling of the shoulder are the most frequent manifestations, but it occasionally can develop rapid osteoarticular destructive lesions (in less than six weeks), which raise the diagnostic possibility of septic arthritis and some tumours We present the report of two men with septic arthritis of the shoulder associated with neuropathic arthropathy secondary to syringomyelia. Both patients presented with sudden shoulder pain exacerbated by either passive or active joint movements, malaise and fever.

[Primary hypertrophic osteoarthropathy (pachydermoperiostosis). Report of two familial cases and literature review].

The primary hypertrophic osteoarthropathy (pachydermoperiostosis) is a hereditary disease characterized by skin thickening (pachydermia), finger clubbing, and proliferation of periosteum (periostitis) with subperiosteal new bone formation. We describe the cases of two brothers of 30 and 24 years, who consulted due to bone pain, arthralgia and oligoarthritis. Pachydermia, hyperhidrosis, seborrhea, digital clubbing, periostosis and non-inflammatory effusions of the knees.

[Coxsackie virus infection associated with myositis and polyarthritis].

A wide spectrum of muscle disorders caused by Coxsackie B virus, ranging from acute nonspecific myalgia to rhabdomyolisis have been described. Arthritis in not widely recognised as an either manifestation of Coxsackie virus infection, and only ten patients has been reported previously. A case of polymyositis and polyarthritis associated with primary Coxsackie B infection in a 6-year-old girl is reported.

[Pneumococcal spondylodiscitis and pleural effusion. Report of a case and literature review].

Streptococcus pneumoniae osteomyelitis in adults appears to be a rare event and, apart from isolated case reports, vertebral osteomyelitis due to this pathogen has rarely been reported. We described a immunocompetent 73-year-old woman who was admitted for fever, abdominal and inflammatory back pain. She was diagnosed of T10-T11 spondylodiscitis and right pleural effusion based on computed tomography and magnetic resonance imaging.

[Pyomyositis, sacroiliitis and spondylodiscitis caused by Staphylococcus hominis in a immunocompetent woman].

In absence of risk factors, osteoarticular infections by coagulase-negative staphylococci are very infrequent. We described the case of a immunocompetent 73-year-old-woman that suffered pyomyositis, left sacroiliitis and spondylodiscitis involving the first and second thoracic vertebrae by Staphylococcus hominis. This multifocal infection occurred five-weeks after intramuscular administration of NSAI for treatment of low back pain associated with a herniated disc L4-L5.

[Prosthetic knee infection caused by Listeria monocytogenes in a woman with rheumatoid arthritis and Waldenström s macroglobulinemia].

Listeria are gram-positive bacilli that can be isolated from soil and in the normal fecal flora of many mammals. It is a uncommon pathogen in the general population, but immunocompromised individuals can develop several focal infections, most notably meningoencephalitis and sepsis. Nevertheless, infectious arthritis caused by Listeria monocytogenes is a exceptional event.

[Synovial chondromatosis. A study of 39 patients].

Objective: To study the clinical manifestations, use of diagnostic imaging techniques and outcome of patients with synovial chondromatosis in our health area.

Patients And Methods: POVISA Hospital provides health services to a population of 127,000 inhabitants. The clinical histories of all the patients in this area who were histologically diagnosed with synovial chondromatosis between January 1992 and December 2003 were reviewed.

[Erdheim-Chester disease and Langerhans histiocytosis. A fortuitous association?].

Erdheim-Chester disease is an idiopathic systemic histiocytosis hystologically different to Langerhans histiocytosis which is characterized by symmetric sclerotic bone lesions, predominantly affecting the diaphyseal and metaphyseal areas of large bones. It is not classified within malignant histiocytosis, but the clinical course tends to be aggressive with a poor response to different schedules of treatment. In rare cases the association of both entities has been reported: Erdheim-Chester disease and Langerhans histiocytosis.

[Infectious spondylodiscitis in a health area of Galicia (Spain) from 1983-2003].

Objective: To study the clinical-epidemiological characteristics of infectious spondylodiscitis (IS) in adults of our health area in the late 20 years.

Material And Methods: We performed a retrospective analysis of the medical records of adult patients with a diagnosis of both, tuberculous (TS) and non tuberculous spondylodiscitis (NTS), between January 1983 and December 2003. The diagnosis was made when compatible clinical-radiological picture were present in association with at least two positive blood cultures and/or micro-organism recovery from vertebral samples.

[Spinal epidural involvement as presentation form of non-Hodgkin's lymphoma: report of 6 cases].

Spinal cord compression and radicular involvement are infrequent events in the natural history of non-Hodgkin's lymphoma, which usually are secondary to invasion of spinal extradural space, and rarely are the presenting manifestations of this condition. Thoracic segment is predominantly affected, but any spinal region can be affected. Histologically, the spinal tumour are frequently a high-grade B lymphoma with aggressive behaviour.

[Peripheral septic arthritis in adults. Epidemiologic study in a Galician health area].

Background: Both, clinical and biologic manifestations of septic arthritis are long been know, but few studies of its epidemiological aspects are well-documented. Literature concerning epidemiological aspects of septic arthritis remains exceptional in Galician Autonomic Community.

Objective: The aim of this investigation was to study the etiopathogenesis and epidemiological characteristic of septic arthritis in the adult population from hospital county of Servicio Galego de Saúde (SERGAS).

[Auto-induced eosinophilic panniculitis: a diagnostic dilemma].

Eosinophilic panniculitis is characterized by a prominent infiltration of subcutaneous fat with eosinophils. The clinical spectrum of lesions that display pathologic changes of eosinophilic panniculitis is diverse, but nodular lesions are the most common. The factitial eosinophilic panniculitis are exceptional, show a pleomorphic pattern of findings and are associated with personality disorders.

The influence of vitamin B2 intake on the activation coefficient of erythrocyte glutation reductase in the elderly.

Objective: To evaluate the influence of dietetic vitamin B2 on the activation coefficient of erythrocyte glutation reductase (alpha-EGR) of a group of elderly people.

Design: The study subjects were 133, independently-living elderly people, between 65 and 90 years of age. A dietetic study was performed using a 7-day food record.

[Disseminated extrapulmonary tuberculosis with skin, lymph node and bone involvement].

Disseminated extrapulmonary tuberculosis is uncommon in no immunocompromised hosts. We described the case of a 68-year-old HIV seronegative man, who presented with a 5 months history of constitutional symptoms, generalized lymphadenopathy, evening fever, osteomyelitis of the left fibula and cutaneous lesions (papules and pustules). There was neither clinical nor radiological evidence of pulmonary involvement.
