[Long QT syndrome and polymorphic ventricular tachycardia due to hypopituitarism. Report of one case].

Symptoms of hypopituitarism are usually chronic and nonspecific, but rarely the disease can have acute and life threatening manifestations. We report a 53 years old female with a pituitary adenoma that was admitted to our hospital because of syncope. The electrocardiogram showed sinus bradycardia with a prolonged QT interval.

In-vitro radiosensitivity in patients with systemic lupus erythematosus.

To determine the "in-vitro" intrinsic cell radiosensitivity (RS) as a risk indicator of radiation-related side-effects in patients with systemic lupus erythematosus (SLE) compared with healthy subjects (control group). Moreover, we elucidated if clinical, therapeutic and biological parameters could affect the "in-vitro" intrinsic RS in patients with SLE. Intrinsic RS was determined by the quantification of the initial radiation-induced DNA double-strand breaks in peripheral lymphocytes, measured by pulsed-field gel electrophoresis from 52 patients with SLE and a control group consisting of 48 sex- and age-matched healthy subjects.

[Intolerance to hydroxychloroquine marketed in Spain (Dolquine) in patients with autoimmune conditions].

Basis: A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation.

Patients And Method: A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted.

[Predictive factors of hypertension in patients with diagnostic doubts of persistent hypertension].

Background: White coat hypertension (WCH) is a prevalent clinical situation which requires a therapeutic management different from persistent hypertension (PH). To distinguish between patients with WCH and uncertain hypertension from patients with PH, an ambulatory blood pressure monitoring (ABPM) is usually indicated, yet it is not available in primary care. Thereby, predictors of WCH on the basis of pre-test (pre-ABPM) clinical characteristics have been suggested.
