[Fever of unknown origin and tuberculous aortitis].

We present the case of a silicotic patient, with recurrent febrile episodes during the past three years, who was hospitalized for the study of prolonged fever. In addition to compliance with the criteria of fever from unknown origin (FUO), the patient presented semiology and echocardiogram compatible with infectious endocarditis. Later on, he developed a severe aortic failure refractary to medical treatment and hence, he underwent surgery. The surgical intervention showed an abscess in the aortic root, which resulted to be of a tuberculous origin and an intact aortic valve. The review of the echocardiographic study allowed the detection of an image compatible with aortic abscess. We comment on the characteristic of this rare entity and the peculiarities of this case, which fulfill the criteria of what has been recently named recurrent or episodic FUO and among whose causes Mycobacterium tuberculosis had not been detected up to now.

[Epidemiology of community-acquired pneumonia in the Health Area I of Navarra].

BACKGROUND: During one year (1988), a protocol study of the community-acquired pneumonias was carried out in patients referred to the Hospital Virgen del Camino in Pamplona (Health Area I or Northern Navarra), so as to have an epidemiological and microbiological knowledge of this disease in this geographic area. METHODS: A clinical protocol, microbiological investigation, 3 blood cultures, Gram stain and sputum culture and serological tests at admission and 20 days later (complement fixing antibodies and indirect immunofluorescence) were carried out. Chest radiographs were carried out on admission, on the third and seventh hospital days and subsequently depending on the evolution. RESULTS: The causative organism was found in 141 of the 225 included patients (62%). Two or more organisms were identified in 19 (8%). In 84 (38%) no microorganism was found. The results for the causative organisms and their frequency were: Pneumococcus 12%, mycoplasma 12%, other bacteria (including Legionella) 11%, Q fever 8%, viruses 7%, and psitaccosis 4%. In 59% of patients there was an underlying disease and 39% developed complications. 4% of patients died. CONCLUSIONS: 22% of the community acquired pneumonias were cared for in the hospital, representing 6% of the admissions to the Internal Medicine Service. The etiologic diagnosis was made in 62% of the community-acquired pneumonias. 23% were of bacterial origin (including Legionella) and 31% were nonbacterial. There was a high incidence of pneumonias caused by Mycoplasma pneumoniae and Coxiella burnetii.
