Intervenção Percutânea Urgente no Enfarte Agudo do Miocárdio por Lesão do Tronco Comum

BACKGROUND: ST-elevation myocardial infarction (STEMI) with the culprit lesion in the left main artery is a rare cardiac emergency with a poor prognosis. OBJECTIVE: Review and prognosis evaluation of primary percutaneous coronary intervention (PCI) performed in the setting of STEMI with left main occlusion in a single high-volume center. METHODS: Of the 483 primary or rescue PCIs performed and followed in our hospital during a 24-month period (August 2004 to July 2006), we retrospectively evaluated those involving left main procedures and analyzed in-hospital mortality and major cardiac events (MACE) in a 12-month follow-up. We found nine patients, age 68 +/- 9 years, five male, seven with multivessel disease and two with isolated left main disease. Rescue PCI was performed in three patients and primary PCI in the others. RESULTS: Seven patients presented in cardiogenic shock and two were classified in Killip class II on admission. Inotropic drugs, intra-aortic balloon pump and abciximab were used in eight patients. Drug-eluting stents were used in six patients, bare-metal stents in two, and isolated balloon angioplasty in one. Five patients (55%) died in the hospital and the four discharged home (two of them aged 81 and 82 years) were still alive and free from MACE at 12-month follow-up. CONCLUSIONS: Clinical presentation of STEMI with the culprit lesion in the left main artery was very severe. During PCI, drug-eluting stents, intra-aortic balloon pump and abciximab were used in almost all patients. This entity had a high mortality rate even though primary PCI was performed. Those who survived had a good mid-term prognosis.

Síndrome de Sjögren

O presente trabalho consta de duas partes estando incluída na primeira a revisão teórica e conceitos actuais sobre o tema e na segunda, a casuística do serviço de Estomatologia do Hospital Pulido Valente. De Abril de 1989 a 1991 (2 anos) vem sendo realizado um estudo sobre o Síndrome de SJÖGREN (Primário e Secundário) de carácter multidisciplinar tendo tido a particular colaboração do Instituto Português de Reumatologia. Com este trabalho pretendemos demonstrar a importância da avaliação oral no estudo das doenças multissistémicas bem como estabelecer critérios de diagnóstico para a população portuguesa. Avaliámos 80 casos suspeitos de Síndrome Sjögren, 66 completamente estudados e cujo motivo da consulta foram a Xerostomia/Xeroftalmia/Hipertrofia das Glândulas parótidas, sintomas estes isolados ou em associação com outras patologias e após terem sido eliminadas outras causas dos mesmos. Tivemos que estabelecer os valores de referência salivares para a população portuguesa em 21 indivíduos voluntários e saudáveis (grupo de controle). A Xerostomia foi avaliada pela Sialoquímica, Sialografia, Cintigrafia e Biópsias do lábio inferior e da glândula sublingual. O exame oftalmológico foi efectuado no serviço de Oftalmologia do Hospital de Santo António dos Capuchos pelos testes de Schirmer, Rosa de Bengala e Ruptura Lacrimal. Apesar do Síndrome de Sjögren, até à presente data, estar muito pouco definido em relação à terapêutica, estes doentes necessitam de cuidados médicos e a Estomatologia tem um papel fundamental sob ponto de vista diagnóstico e terapêutico. Fica-se assim com a noção de que este síndrome não é tão infrequente como se poderia pensar e a avaliação da vertente oral é importante para o estabelecimento do grau da doença e seu tratamento.

Intramural Hematoma of the Esophagus After Thrombolysis for Ischemic Stroke

Intramural dissecting hematoma is an unusual esophageal condition with a threatening presentation but excellent prognosis when managed conservatively.We report the case of an 88-year-old woman who developed an intramural hematoma of the esophagus after intravenous thrombolysis for an acute ischemic stroke. Before thrombolysis, nasogastric intubation was attempted unsuccessfully. She was kept on nil by mouth, intravenous hydration, proton pump inhibitor, antiemetics,and an antibiotic initiated 2 days before for periodontal disease. The esophageal hematoma regressed, and she resumed oral diet asymptomatically.To our knowledge, this is the first report of this type of lesion after thrombolysis for an ischemic stroke. A brief discussion and literature review are presented.
