Arterial hypertension in the female world: pathophysiology and therapy.

Hypertension is a major risk factor for cardiovascular disease and outcomes in women, and antihypertensive therapy is not always successful in achieving control over the blood pressure (BP). Nonoptimal control of BP remains a crucial risk factor for cardiovascular mortality, and in women, it could be related to sex-specific factors. Historically, women have been under-represented in clinical trials; therefore, the benefits of clinical outcomes and the safety profiles of antihypertensive therapies have been studied less extensively in women.

[Hypertrophic cardiomyopathy during adrenocorticotrophic hormone administration in infants: a case report].

We report a 2-month-old child with infantile myoclonic seizures, who developed congestive heart failure secondary to hypertrophic cardiomyopathy while receiving adrenocorticotropic hormone (ACTH) therapy. Treatment with propranolol and withdrawal of ACTH led to the resolution of cardiac hypertrophy as determined by two-dimensional echocardiography. Possible links between ACTH therapy and the development of hypertrophic cardiomyopathy are examined.

Chronic bleeding caused by small bowel angiodysplasia: a problem of recognition and diagnosis.

Angiodysplasia of the gastrointestinal tract is a disorder consisting of ectasia of submucosal and mucosal vessels, which causes acute and chronic bleeding. We describe the case of a 58-year-old man with a history of recurrent lower intestinal bleeding and severe anemia. Endoscopy and X-ray examination of the gastrointestinal tract failed to show the source of bleeding.

[Discordance between clinical and immunological aspects in a case of chronic B-type lymphoproliferative syndrome].

Chronic lymphoproliferative disorders are extremely heterogeneous from a clinical, morphological and immunological point of view. The paper reports the case of a woman with chronic prolymphocytic leukemia. The neoplastic clone revealed the typical immunological features of pre-B lymphocytes, which are at an earlier stage of differentiation in respect to prolymphocytes.

[Ventricular afterload and transmitral Doppler flow profile: effects of the diving test].

The influence of loading conditions on mitral flow velocity profile was studies by pulsed wave Doppler echocardiography in 10 normal subjects during diving test (5 min face exposure to iced water). The cold stimulus increased blood pressure (p less than 0.001), peripheral resistances (p less than 0.

POEMS syndrome: a case report.

A case of POEMS syndrome in a 43-year-old male with polyneuropathy, osteolytic lesion of the basin due to solitary IgA-lambda plasmacytoma, cutaneous scleroderma-like changes, diffuse lymphadenopathy and hepatosplenomegaly is described. Liver biopsy showed a regenerative process of the parenchyma without laboratory and histologic evidence of necrosis. A peculiar finding was the onset of a right hemiparesis in the absence of signs of vascular disease or other predisposing factors.

Effects of ketanserin on transmembrane sodium transport in erythrocytes.

Ketanserin, an antagonist of 5-HT2-serotonergic and alpha 1-adrenergic receptors, has come into use for the therapy of mild to moderate arterial hypertension. Quite recent observations have shown changes in transmembrane sodium (Na) transport after the acute administration of high doses of this drug to normal subjects. It is well known that some of these transport systems have an altered activity in essential hypertension.

Evidence for a direct and non-receptor-mediated action of 5HT2 antagonists on transmembrane cation transport systems.

Changes in transmembrane sodium fluxes have been reported in normotensive and in hypertensive subjects after ketanserin administration. In this study, the effects of the serotonergic system on transmembrane sodium transport mechanisms have been investigated in vitro. In erythrocytes drawn from ten healthy subjects, we studied the effects of serotonin (5HT) on the Na/K pump, Na/K cotransport, Na/Li countertransport, and passive permeability of Na.

Sublingual and intravenous ketanserin versus sublingual nifedipine in the treatment of severe hypertension: a randomized study.

Thirty-seven patients with severe hypertension were randomly assigned to receive 20 mg of ketanserin sublingually, 10 mg of ketanserin intravenously, or 20 mg of nifedipine sublingually. Systolic and diastolic blood pressures fell significantly after the three treatments. The maximum effects were reached 25 minutes after sublingual ketanserin (with decreases of 7.

Massive haemorrhagic pericardial effusion in beta-thalassaemia major.

The case of a child with beta-thalassaemia major who developed a massive haemorrhagic pericardial effusion is reported and in whom the clinical picture completely resolved after pericardiocentesis. Possible causes are discussed and the role of echocardiography in the follow-up of thalassaemic patients is emphasized.
