[Human immunodeficiency virus type 2 infection in Western Africans living in Catalonia].

We have studied retrospectively the presence of serologic markers of type 1 and type 2 human immunodeficiency virus infection in 102 subjects coming from West Africa and living in Catalonia. We have proven the presence of specific antibodies to type 2 human immunodeficiency virus in three asymptomatic subjects among whose epidemiologic antecedents the unique risk factor was heterosexual promiscuity. These three subjects are the first seropositive to type 2 human immunodeficiency virus reported in our country. In none of the studied cases serologic markers of type 1 human immunodeficiency virus infection were detected.

Amyloid goiter. Diagnosis by fine-needle aspiration biopsy of the thyroid.

Amyloid goiter is a rare condition. We could not find more than 90 cases from an extensive review of world literature. We report here two patients in whom that diagnosis was made, prior to surgery, by fine-needle aspiration biopsy of the thyroid. We review the major clinic and histopathologic characteristics of amyloid goiter and we stand out the usefulness of the fine-needle aspiration biopsy of the thyroid to diagnose the amyloid goiter and amyloidosis, in general.

Real-time ultrasound for diagnosis of symptomatic venous thrombosis and for screening of patients at risk: correlation with ascending conventional venography.

This is a prospective study of 108 patients in two distinct groups undergoing real-time ultrasonography (US) and ascending conventional venography within the same day. The two patient groups consisted of the following: Those patients evaluated because of suspicion of deep venous thrombosis of lower limbs (69 patients) and those at high risk for venous thrombosis (19 patients with a recent hip fracture, 20 with a suspected pulmonary embolism). In the diagnosis group 48 patients had venographic evidence of thrombosis. The predictive value of abnormal findings from real-time US was 97%, and that of a negative study was 75%. Thus, real-time US may have a role as a diagnostic procedure, to be followed by x-ray venography in patients with negative US results. By contrast, real-time US is far less sensitive as a screening test in patients without clinical evidence of thrombosis. Only 3 of 9 patients with thrombosis were detected, with a 50% sensitivity for proximal vein thrombosis. Therefore, the use of real-time US for screening high-risk patients must be limited to very high risk patients in whom other tests are ineffective (as in hip surgery).

[Antibodies against HTLV-1 in patients undergoing multiple transfusions].

HTLV-1 is a retrovirus which causes adult T cell leukemia and is transmitted through contaminated blood products. Patients who have received multiple transfusions are therefore at high risk of HTLV-1 infection. Since it has been postulated that 0.5% of Spanish blood donors present HTLV-1 antibodies, we decided to investigate the presence of these in 154 polytransfused patients in Barcelona. We could not demonstrate the presence of HTLV-1 infection in any of the patients although six of them gave positive ELISA results repeatedly. The validity of tests previously used for the detection of HTLV-1 antibodies is discussed and multicentric studies with a wider population sample are suggested in order to establish the real incidence of HTLV-1 infection in our community.
