[The home treatment of deep venous thromboses with low-molecular-weight heparin]. / Tratamiento domiciliario de las trombosis venosas profundas con heparina de bajo peso molecular.

Low-molecular-weight heparins (LMWH) have shown to be at least as safe and efficient as non-fractionated heparin in the treatment of deep-vein thrombosis (DVT). Moreover, no serial laboratory controls are required. Therefore, LMWH allow the patients to be treated at home. From July 1995 to July 1996, 30 consecutive patients with DVT were enrolled in a prospective study and treated with nadroparin. Ambulatory treatment was feasible in 24 patients (9 patients did not require admission and 15 patients were discharged in less than 6 days). The main causes for admission were the inability to obtain a diagnosis, the severity of symptoms in the involved limb, and the presence of associated disease. None of the 24 patients to whom the possibility of home therapy was offered desired to remain at hospital. The ambulatory care of these patients increased the burden on primary care teams. There was no case of clinical recurrent thromboembolism nor a major hemorrhagic complication. Ambulatory treatment of DVT with nadroparin seems to be feasible, efficient and safe. Nevertheless, before using this therapeutic alternative a series of factors should be considered, which include the severity of clinical presentation, the embolic and hemorrhagic risks, and the presence of associated diseases.

[Visceral leishmaniasis and AIDS. Apropos of 2 cases with different clinical course patterns]. / Leishmaniasis visceral y SIDA. A propósito de dos casos con patrón clínico-evolutivo distinto.

We present two cases of visceral leishmaniasis in patients with AIDS which represent two different clinical patterns of the disease. Special emphasis is made on the need to lavish bone marrow studies in those patients with AIDS who present fever of unknown origin since immunodepression can modify the classical clinical picture of the disease. According to our experience, visceral leishmaniasis should be included amongst the infections indicative of AIDS in patients with HIV infection.
