[Takayasu arteritis and cerebral venous thrombosis: report of a case]. / Arteritis de Takayasu y trombosis venosa cerebral: a propósito de un caso.

Palpitations, paresthesias and anxiety are very common reasons of consultation in primary care. We report the case of a 40 year-old Caucasian woman who came to the clinic due to these symptoms, and was finally diagnosed with Takayasu arteritis. Later, she had an episode of headache, as the initial manifestation of cerebral venous thrombosis. Takayasu arteritis is a systemic vasculitis affecting medium and large arteries, mainly leacausing stenosis of the aorta and its branches. It most frequently affects Asian women, being much rarer in Europe. The primary care doctor plays a key role in the initial diagnosis and monitoring of patients with rare diseases, such as Takayasu arteritis, and must be a basic support for the patient and family, providing information and advice, and contributing with his work to reduce the vulnerability of this group.

["Dizziness" as the first manifestation of a chronic progressive multiple sclerosis]. / "Mareo" como primera manifestación de una esclerosis múltiple primariamente progresiva.

Dizziness is a common consultation in primary care. Most cases of dizziness can be managed in the first level of care. The family physician should be able to discriminate the cases that require referral to a second level, those potentially serious, and those requiring immediate care. We report the case of a patient with long-term dizziness and the diagnosis, clinical course, treatment and prognosis.

[Pulmonary Langerhans cell histiocytosis: report of a case]. / Histiocitosis pulmonar de células de Langerhans: a propósito de un caso.

Pulmonary Langerhans cell histiocytosis is a rare disease of young adults, usually smokers, which is associated with significant morbidity. The course of the disease is unpredictable, ranging from benign self-limiting types with spontaneous regression, to malignant forms with progression to respiratory failure and death. Its cause is unknown, but most authors believe that there is an alteration in immune system regulation in these patients. We report a case of a patient with the diagnosis of pulmonary Langerhans cell histiocytosis and review the clinical characteristics, diagnosis and treatment of this disease. We consider this case of interest due by the low frequency of this disease.
