Pulmonary metastasis: very late relapse of testicular embryonal carcinoma.

Testicular carcinoma recurrences represent a rare finding (1-6% in non-seminomatous germ cell tumours). However, cases of recurrence have been described many years later. We report a case of late recurrence of embryonic testicular carcinoma, after 26 years, with pulmonary metastases.

Evidence of angiogenesis in bronchial biopsies of smokers with and without airway obstruction.

The involvement of bronchial vasculature in the airway remodelling occurring in symptomatic smokers with normal lung function and with chronic obstructive pulmonary disease (COPD) has been poorly investigated. An immunohistochemical study was performed on bronchial biopsies taken from 8 non-smokers and 18 smokers divided, according to global health initiative on obstructive lung diseases (GOLD) classification of COPD, into two groups, GOLD 0 and GOLD 2, each of 9 subjects. The number of vessels and the percentage of vascular area in the lamina propria were evaluated by mAb anti-collagen IV.

Comparison of the bronchodilating effects of inhaled formoterol, salmeterol and salbutamol in asthmatic patients.

Ten subjects with various degrees of asthma severity underwent a three-day trial, with the aim of evaluating the bronchodilating effect of inhaled formoterol (12 micro g), in comparison with salbutamol (200 micro g) and salmeterol (50 micro g). The bronchodilation afforded by formoterol paralleled that of salbutamol in rapidity (mean percentage increases in functional measurements (FEV(1)) vs. baseline recorded 5 min after drug administration: 7.
