Influence of age on clinical presentation of acute pulmonary embolism.

The aims of this study were to compare the clinical features of patients with pulmonary embolism (PE) and patients in whom the initial suspected diagnosis was not confirmed by the complementary studies and to determine the possible clinical differences among patients with PE according to age. A retrospective review of the charts of a group of patients with PE (n, 96) and another without PE (n, 96) was carried out. The patients with PE over 65 years of age (n, 64) were compared with those under 66 years of age (n, 32).

Germ-line BRCA1 mutations in women with sporadic breast cancer: clinical correlations.

Purpose: Sporadic nonhereditary breast cancer is recognized as the most common form of this malignancy. Presence of germ-line mutations in the BRCA1 gene of these tumors is an infrequent event. We undertook the present study to evaluate the prevalence of germ-line mutations in patients diagnosed with sporadic breast cancer, and to delimit the clinical spectrum of this subgroup of patients with germ-line mutations and their differences with respect to patients with no evidence of BRCA1 gene mutations.

[Endobronchial inflammatory pseudotumor. A case report and review of the literature].

The endobronchial inflammatory pseudotumor is a little described variant of inflammatory lung pseudotumor, the growth of which is directed towards bronchial lumen. A case is presented and seventeen other well documented cases from the medical literature are reviewed. This variant has been frequently observed with clinical manifestations of obstructive respiration and atelectasis as a radiologic pattern allowing detection at an early age.

Rewarming rate of the myocardium during aortic cross-clamp time: variations with different levels of body hypothermia.

Twenty patients underwent elective cardiac valve replacement at 20 degrees C of body hypothermia. Temperatures of the ventricles of both walls were monitored on 12 different sites. Distribution of myocardial temperature ranged between 24.
