Osteoporose (OP) - prevenção e tratamento, uma visão atual

A osteoporose e suas conseqüências têm despertado, por ser considerada um problema moderno de saúde pública, a atenção dos governos, especialmente dos países desenvolvidos e, mais recentemente, daqueles considerados em desenvolvimento ou semi-industrializados. Com o apoio da mídia nacional e internacional, a divulgação dos conhecimentos e informações nessa área da patologia médica tem propiciado a milhoes de seres humanos em todo o mundo, refletir sobre as nefastas conseqüências dessa síndrome que hoje sabemos, começa a ser desenvolvida na infância e na puberdade, quando o patrimônio ósseo está sendo estabelecido, por meio da indução genética

Nonsteroid anti-inflammatory drugs

Non-steroidal anti-infl ammatory drugs are the most frequentlyprescribed medications worldwide. In the United States, around 17million people use daily these drugs, because many of them canbe bought as over the counter medication, and approximately 60million prescriptions are made yearly. The majority of users are oldpeople. These drugs have shown to be effective for symptomaticinfl ammatory pain relief whether acute or chronic, mainly in muscularskeletal pain syndromes

Echocardiographic Abnormalities and Antiphospholipid Antibodies in Patients with Systemic Lupus Erythematosus

OBJECTIVE: Lupus anticoagulant and anticardiolipin antibodies (aCL) have been associated with thrombosis, recurrent abortion, and thrombocytopenia in patients with systemic lupus erythematosus (SLE), but their relationship with cardiac disease is less clear. The purpose of this study was to evaluate the association between antiphospholipid antibodies (aPL) and echocardiographic abnormalities in patients with SLE. METHODS: A total of 70 consecutive patients and 42 control subjects underwent M-mode, 2-dimensional and Doppler echocardiography and tests for lupus anticoagulant, aCL IgG, IgM, and IgA. Lupus anticoagulant was assayed with the dilute Russell viper venom time, and aCL IgG, IgM, and IgA were measured by an enzyme-linked immunosorbent assay (ELISA). RESULTS: Lupus anticoagulant showed a prevalence of 10%. As a whole, aCL had a prevalence of 44.3% and aPL had a prevalence of 50%. Patients with echocardiographic abnormalities had a prevalence of 54.3% and showed a trend towards an association with aCL IgG (P=0.06). The presence of pulmonary hypertension (PH) was significantly associated with aCL IgG (p=0.02). CONCLUSION: aCL IgG was significantly associated with PH and showed a strong trend towards an association with echocardiographic abnormalities taken together. These findings suggest a role for aCL IgG in the development of lupus cardiovascular disease

Manifestações otorrinolaringológicas nas doenças reumáticas auto-imunes Otorhinolaryngologic manifestations of autoimmune rheumatic diseases

As manifestações otorrinolaringológicas nas doenças reumáticas representam um desafio diagnóstico para o reumatologista, o otorrinolaringologista e o médico generalista. Comumente, sintomas otorrinolaringológicos representam um sinal inicial de uma doença assintomática ou uma desordem auto-imune não diagnosticada, que freqüentemente exige um imediato e agressivo tratamento imunossupressor. Distúrbios auditivos podem ser vistos em pacientes com lúpus eritematoso sistêmico (LES), granulomatose de Wegener (GW), policondrite recidivante (PR), poliarterite nodosa, síndrome de Cogan, síndrome de Sjögren e menos freqüentemente na síndrome de Churg-Strauss e doença de Behçet. O nariz e seios paranasais são variavelmente afetados durante o curso da GW, síndrome de Churg-Strauss, PR e sarcoidose. Ulcerações mucosas recorrentes são comuns no LES e doença de Behçet. Xerostomia é uma manifestação comum da síndrome de Sjögren primária e secundária; aumento da glândula salivar pode ser visto nesses pacientes, assim como nos pacientes com sarcoidose. A articulação cricoaritenóide pode ser envolvida durante o curso da artrite reumatóide, espondilite anquilosante e gota; alterações osteoartríticas também têm sido descritas. Disfunção do nervo trigeminal pode ocorrer em pacientes com síndrome de Sjögren, esclerose sistêmica, LES e doença mista do tecido conjuntivo. Paralisia facial periférica tem sido descrita como complicação do curso da síndrome de Sjögren e sarcoidose.Otorhinolaryngologics manifestations of rheumatologic disorders represent a diagnostic challenge for the rheumatologist, the otorhinolaryngologist, and the general practicioner. Not uncommonly otorhinolaryngologics symptoms represent the initial sign of an otherwise asymptomatic or even undiagnosed autoimmune disorder which often calls for prompt and aggressive immunosuppressive treatment. Hearing disturbances may be seen in patients with systemic lupus erythematosus, Wegener's granulomatosis, relapsing polychondritis, polyarteritis nodosa, Cogan's syndrome, Sjögren's syndrome, and less frequently in Churg-Strauss syndrome and Behçet's disease. Nose and paranasal sinuses are variably affected during the course of Wegener's granulomatosis, Churg-Strauss syndrome, relapsing polychondritis and sarcoidosis. Recurrent mucosal ulcerations are common in systemic lupus erythematosus and Behçet's disease. Xerostomia is a common feature of primary and secondary Sjögren's syndrome; salivary gland enlargement may be also seen in these patients, as well as in patients with sarcoidosis. The cricoarytenoid joint can be involved during the course of rheumatoid arthritis, ankylosing spondylitis and gout; osteoarthritic changes have also been described. Trigeminal nerve dysfunction may occur in patients with Sjögren's syndrome, systemic sclerosis, systemic lupus erythematosus and mixed connective tissue disease. Peripheral facial nerve palsy has been described to complicate the course of Sjögren's syndrome and sarcoidosis

Síndrome do impacto posterior do tornozelo: um diagnóstico que deve ser lembrado pelo reumatologista. Relato de dois casos Posterior ankle impingement syndrome: a diagnosis rheumatologists should not forget. Two case reports

O tornozelo é sítio frequente de sintomas dolorosos em atletas e não atletas. A dor localizada na região posterior pode ser o resultado final de diversas patologias, sendo um desafio diagnóstico para o reumatologista. A síndrome do impacto (pinçamento) posterior do tornozelo, também denominada síndrome os trigonum e síndrome compressiva tibiotalar posterior, é um distúrbio clínico caracterizado por dor aguda ou crônica na região posterior do tornozelo, desencadeada pela flexão plantar forçada, que promove microtrauma crônico repetitivo. A patologia do processo os trigonum-talar é a causa mais comum dessa síndrome, mas existem outras causas, como tenossinovite do flexor longo do hálux, osteocondrite de tornozelo, doença da articulação subtalar e fratura. O diagnóstico baseia-se na história clínica e exame físico, e complementado por achados na radiografia simples (RX), ultrassom (US), cintilografia, tomografia computadorizada (TC) e ressonância magnética (RM). Destacamos o RX por seu baixo custo e boa sensibilidade, o US pela possibilidade de guiar infiltrações terapêuticas e a RM pela possibilidade de avaliar partes moles adjacentes.<br>The ankle is a common site of painful symptoms in athletes and nonathletes. Posterior ankle pain can be the end result of several pathologies, and a diagnostic challenge for rheumatologists. The posterior ankle impingement syndrome, also known as os trigonum syndrome and posterior tibiotalar compression syndrome, is a clinical disorder characterized by acute or chronic posterior ankle pain triggered by forced plantar flexion, which causes chronic repetitive microtrauma. Pathology of the os trigonum-talar process is the most common cause of this syndrome, but there are other causes, such as tenosynovitis of the flexor hallucis longus, ankle osteochondritis, subtalar joint disease, and fracture. Diagnosis is based on clinical history and physical examination, and complemented by findings on plain radiography (RX), ultrasound (US), scintigraphy, computed tomography (CT), and magnetic resonance imaging (MRI). It is worth noting that RX has low cost and good sensitivity, US can provide guidance to therapeutic infiltrations, and MRI allows the assessment of surrounding soft tissues

Behçet's syndrome / AIDS / cerebral toxoplasmosis: an unusual association

Few cases of AIDS associated to manifestations suggesting Behçet's syndrome have been reported. This case is of a young married woman who presented, during a period of 7 years, clinical manifestations consistent with the late diagnosis of Behçet's syndrome, when she developed recurrent lymphomonocytic meningoencephalitis. At this time, she was found to be infected by HIV-1. Immunosupressive doses of glucocorticoid produced an unsatisfactory response and she evolved to death due to CNS toxoplasmosis. The latter diagnosis was presumed on the basis of magnetic resonance imaging findings and proved by necropsy after her third hospital stay. One of the factors hindering the appropriate diagnosis was the low level of CD4 and the CD4/CD8 ratio, sometimes observed in active Behçet's syndrome and higher than those observed in patients with this severe opportunistic infection. No information about the exact period of time she had been infected with HIV-1 is available. So, we do not know whether both diseases were overlor, if the patient, infected by HIV-1, developed an unusual clinical feature consistent with Behçet's Behçet's syndrome, and subsequently evolved to AIDS
