Afectación articular en un paciente joven con enfermedad de Still del adulto: a propósito de un caso / Joint involvement in a young patient with adult Still's disease: in relation to a case

Introducción: La enfermedad de Still del adulto es una enfermedad reumática, inflamatoria, sistémica y crónica que generalmente comienza sobre los 40 años de edad, pero puede aparecer en edades más tempranas. Se caracteriza por gran variedad de manifestaciones generales, articulares, fiebre y rash principalmente. Etiopatogénicamente, el proceso inflamatorio crónico que se genera durante el curso de la enfermedad es el responsable de las manifestaciones clínicas y del daño articular que se produce. Objetivo: dar a conocer los elementos básicos para el diagnóstico de la enfermedad de Still del adulto. Caso clínico: se presenta el caso de un paciente masculino, de 21 años de edad, que acude a consulta con manifestaciones clínicas que permiten realizar el diagnóstico de una Enfermedad de Still del Adulto. Conclusiones: La enfermedad de Still del Adulto, a pesar de no tener un patrón de deformidades tan amplio como la artritis reumatoide, también produce daño articular que puede comprometer la función de la articulación afectada. Resulta importante identificar precozmente las manifestaciones clínicas que hacen sospechar su diagnóstico para minimizar, retrasar o prevenir la afectación de las articulaciones(AU)

Introduction: adult Still's disease is a rheumatic, inflammatory, systemic and chronic disease that usually begins around 40 years of age, but may appear at younger ages. It is characterized by a great variety of general, joint, fever and rash manifestations. Etiopathogenically, the chronic inflammatory process that is generated during the course of the disease is responsible for the clinical manifestations and joint damage that occurs. Objective: to present the basic elements for the diagnosis of adult Still's disease. Clinical case: the case of a male patient, 21 years of age, who comes to the clinic with clinical manifestations that allow the diagnosis of an Adult Still's Disease. Conclusions: adult Still's disease, despite not having a pattern of deformities as extensive as rheumatoid arthritis, also produces joint damage that can compromise the function of the affected joint. It is important to identify early clinical manifestations that make your diagnosis suspect to minimize, delay or prevent the involvement of the joints(AU)

The Result of Revision Total Hip Arthroplasty in Patients with Metallosis Following a Catastrophic Failure of a Polyethylene Liner

BACKGROUND: Wear cannot be completely prevented after total hip arthroplasty. If severe polyethylene (PE) liner wear develops, the so-called catastrophic failure occurs and metallosis develops. We postulated that longevity of the new implant may be affected after revision surgery for metallosis following a catastrophic failure of a PE liner due to the substantial amount of PE wear particles and infiltration of the metal particles in this catastrophic condition. METHODS: Twenty-three hips of 23 patients were identified because they showed metallosis during revision total hip arthroplasties performed in Seoul National University Hospital between January 1996 and August 2004. They were followed for at least 6.5 years after the index revision total hip arthroplasty. The clinical and radiological results of revision total hip arthroplasties in these patients were evaluated. RESULTS: The median Harris hip score increased from 60 points before revision total hip arthroplasties to 90 points at the final follow-up. Osteolysis was detected at an average of 9.3 years after revision total hip arthroplasties in 13 hips and acetabular cup loosening at average 9.8 years after revision total hip arthroplasties in 9 hips. With radiographic evidence of osteolysis and loosening as the end points, the 15-year survival rates were 28.2% and 56.0%, respectively. CONCLUSIONS: The survival rate of revision total hip arthroplasty in patients with metallosis following a catastrophic failure of a PE liner was low.

Evaluation of Shoulder Disorders by 2-F-18-fluoro-2-deoxy-D-glucose Positron Emission Tomography and Computed Tomography

BACKGROUND: Although flourine-18-flourodeoxyglucose (FDG) positron emission tomography (PET) has a limitation for localizing anatomical structures, combining it with computed tomography (CT) has made it more efficient for overcoming such limitations. This study aims to evaluate the efficacy of PET/CT for evaluating diseases of the shoulder. METHODS: Retrospective examination was performed on 25 patients who underwent FDG-PET/CT scanning. All the patients were over 60 years of age, and they were evaluated both clinically and radiologically for shoulder pain. The study period was from May, 2006 to May, 2008. One of the patients had metastatic lesion in a shoulder and this patient was excluded from the study, so the total number of subjects in the study was finally 24 patients. RESULTS: PET/CT showed 67% sensitivity, 73% specificity, a positive predictive value of 60%, a negative predictive value of 79%, 27% false positivity and 33% false negativity concerning shoulder pain. PET/CT showed negative finding in 4 cases that were successfully treated by operative treatment (rotator cuff tear [RCT], 3 cases; impingement syndrome, 1 case). Negative findings were also noted in 6 cases in which the pain subsided after conservative treatment (RCT, 1 case; suspected RCT, 2 cases; impingement syndrome, 3 cases). All the patients with osteoarthritis and rheumatoid arthritis had positive findings on PET/CT scanning. CONCLUSIONS: PET/CT is a useful adjunct to the existing imaging modalities to assess functional and pathophysiologic processes and at a very early stage, and so PET/CT can help physicians make better preoperative and postoperative decisions on treatment.
