RESUMO
In order to establish if neuropsychiatric systemic lupus erythematosus (NPSLE) can be identified by any characteristic other than those used to diagnose the neuropsychiatric (NP) disease itself, we retrospectively reviewed 98 systemic lupus erythematosus (SLE) patients followed over a mean period of 10 years. NPSLE was identified in 22 patients. Stroke and generalized seizures were the most frequent NP manifestations. The NPSLE and non-NPSLE groups were similar with regard to demographic characteristics, ACR criteria, serum autoantibodies, and frequency of hypertension and hypercholesterolemia. Of note, compared to the non-NPSLE group, NPSLE was associated with a higher frequency of smoking (78 versus 26%), organ damage (73 versus 34%), and cumulative mortality rate (14 versus 7%). The series of patients was further analysed according to the presence of antiphospholipid syndrome (APS). Significantly, the interval between the onset of NP disease and SLE diagnosis was shorter in the APS(-) (0.3 ± 1 years) than in the APS(+) (5 ± 7 years) groups. Recurrence and/or persistence of NP events were only documented in the APS(-) group. Overall cumulative mortality was highest in NPSLE and in APS(+) patients with inadequate anticoagulation control, identifying an aspect that requires improved vigilance and the development of novel therapeutic modalities.
RESUMO
Infective endocarditis can be associated with complex clinical presentations, sometimes with a difficult multi-disciplinary management. Actinobacillus actinomycetemcomitans belongs to the Haemophilus species, Actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella species group, responsible for 5% to 10% of infective endocarditis in native heart valves. These organisms have slow fastidious growth pattern, often associated with negative cultures, and cause systemic embolism with abscess formation. The authors present the case of a 59-year-old man, admitted due to fever of unknown origin, with a personal history of obstructive hypertrophic cardiomyopathy and recent dental manipulation. The diagnosis of mitral valve's endocarditis was established after a transoesophageal ecocardiography, with a late isolation of A actinomycetemcomitans in blood culture. Despite the institution of antibiotic therapy, the patient suffered from multiple episodes of septic embolism: skin, mucosae, cerebral abscesses, spondylodiscitis and uveitis. He was submitted to heart surgery with miectomy and replacement of the native mitral valve by a mechanical prosthesis, while on antibiotics.

Malignant lymphomas represent about 9% of cardiac neoplasms. Despite its life-threatening nature, the cardiac manifestations are often subclinical. In about 20% of deaths from lymphoma, cardiac involvement is found only in autopsy. The authors present the case of a 77-year-old female admitted due to intense back pain, vomiting, generalised pruritus, fatigue and weight loss. She had a personal history of hypertension and breast cancer was noted 10 years before admission. The thoracoabdominopelvic CT showed a mass in the left atrium with extension to the right atrium and inferior vena cava, and a paravertebral mass at D10-D11 with invasion of the spinal canal and hepatic hilum. The transthoracic paravertebral mass biopsy was compatible with a diffuse large B cell lymphoma. The patient developed a complete atrioventricular block, with haemodynamic instability, requiring urgent chemoreduction of the paracardiac mass and implantation of an epicardial pacemaker.

Buerger's disease or Thromboangiitis obliterans is a segmental inflammatory disease that affects the vessels and nerves of the extremities. It usually affects men below 45 years old and correlates with tobacco, as a predisposing factor. The authors present the case of a 34-year-old male, with ulcers in the fingertips with progressive worsening: acrocyanosis, slow healing, necrosis and finally loss of substance. Dorsalis pedis and posterior tibial pulses were not palpable. Personal history of heavy smoking was (20 pack-years). The angiography revealed proximal occlusion of the left posterior tibial and interosseal arteries, with distal circulation by the anterior tibial artery. He was submitted to disarticulation of the second left toe and therapy with pentoxifyline and iloprost infusion, calcium antagonist, antiplatelet drugs, statin and low molecular weight heparin (later replaced by oral anticoagulation). Improvement was seen of active vascular lesions and pain symptoms.
