RESUMO
Stevens-Johnson syndrome is characterized by generalized exanthema associated with high fever, catarrhal symptoms and mucositis. Various etiologies have been implicated, particularly numerous medications and certain agents of atypical pneumonia. Stevens-Johnson syndrome leads to death in up to 5% of cases. We describe the case of a 30-year-old woman with bilateral atypical pneumonia accompanied by severe generalized exanthema that required hospitalization in the serious burns unit of our hospital. She was diagnosed with Stevens-Johnson syndrome following atypical pneumonia caused by Mycoplasma pneumoniae with microbiological and pathological confirmation.

Antiphospholipid syndrome (APS) is defined by the presence of arterial and venous thromboses, recurrent fetal death, cerebrovascular accidents, hemolytic anaemia, thrombocytopenia and various other manifestations in different organs. APS is a clinical entity that can appear commonly alongside systemic lupus erithemathous on it can occur as a primary disease. The syndrome is defined by the presence of antiphospholipid antibodies in serum, a group of immunoglobulins (IgG, IgM, IgA or an mixture of them) that adopt an hexagonal configuration when they are incubated at 37grades C. In APS, it is rather common to find cardiac lesions such as non-verrucous endocarditis, valvular lesions (especially of the mitral valve), microvascular cardiac disease and more risk of thrombosis at this level, myxomas that could be the cause of a systemic inflammation in relation to the production of antiphospholipid antibodies, intracardiac thrombii and congenital heart disease. We present the case of a woman with APS associated with interauricular communication whose initial diagnosis were pulmonary thromboembolism and cerebrovascular stroke. We were able to diagnose the cardiac abnormality by the use of transesophagic echocardiography. We propose the use of this imaging technique for patients with APS even though the transthoracic Doppler echocardiography was found to be normal. In this way we will be able to rule out cardiac lesions which could also be the cause of embolic manifestations.

OBJECTIVE: Our objective was that of describing a series of episodes of upper limb deep venous thrombosis, with special emphasis on the incidence of posthrombotic syndrome and its impact in the quality of life of the patients. METHODS: 33 episodes (29 patients) of upper limb deep venous thrombosis were studied, between January 1995 and January 2002; episodes until September 1999 (18 episodes) were considered retrospectively while those which took place starting in this date (15 episodes) were considered prospectively. In all, 24 patients were cared in hospital clinic. It was possible to obtain complete data in 16 cases, in which evolution toward posthrombotic syndrome, venous revascularization, and impact of the pathological process in the global quality of life of patients were studied. RESULTS: Average age of patients was 58.9 years. In 25 episodes (75.8%) some risk factor for venous thrombosis existed, the presence of a venous catheter being the most frequent. Subclavian axillary affectation was predominant (18 episodes, 55%) and in the left side (25 episodes, 76%). Twenty-eight episodes were diagnosed with echography (84.8%). Mean D-dimers concentration (N = 16) was 1,046 ng/ml (standard deviation [SD]: 826.9). One of the episodes (3%) was associated to lung thromboembolism. Treatment consisted on the administration of low molecular weight heparin during the acute phase in 70% of the cases. In 13 episodes (39%) additional treatment of thrombosis (endovascular in most) was carried out. In 29 episodes (88%) chronic treatment was administered with acenocoumarol, while in 4 episodes (12%) the administration of low molecular weight heparin was kept. No patient died during hospitalization. In 15 patients (52%) control of revascularizacion was performed. We detected complete revascularization in 6 patients (40%), revascularization with collateral circulation in 4 patients (27%), partial revascularization in other 4 patients (27%) and presence of permeability but with expansion and tortuosity of deep venous system in 1 case (6%). Posthrombotic syndrome was considered mild or nonexistent in 10 patients (62.5%) and moderate in 6 patients (37.5%). Quality of life of patients with moderate posthrombotic syndrome was significantly worse than that of patients with mild posthrombotic syndrome (73 vs 90, p < 0.035). CONCLUSIONS: Most of upper limb deep venous thrombosis are associated to the use of intravenous catheters. Echography is the primary diagnostic technique. At the time of the diagnosis, patients tend to show elevation in D-dimers levels. Evolution toward posthrombotic syndrome is frequent; this syndrome does not use to be serious but indeed influences the quality of life of patients.

The objective of this work is the study of malaria in the population of our hospital area. The characteristics of 31 cases of imported malaria diagnosed in the University Hospital La Fe of Valencia are described. The study included the period between 1993 and 2002. The predominance of males (81%), of the age group of 20-40 years (average: 37.68), and of the patients native from African countries (all except for a patient from Ecuador) of which 40% came from Equatorial Guinea, were outstanding results. The most prevalent species was Plasmodium falciparum (72%). Only 12.9% of the patients received antimalarial prophylaxis with mefloquine, without appropriate compliance. Malaria continues to be the most important protozoan infection in the world, and currently a possible reintroduction of this infection is observed in Spain. That is why is necessary to improve the information offered to the tourists who visit tropical countries. The clinical suspicion is also essential in patients who come from endemic areas.
