[Strongyloides stercoralis infection in patients with bronchial obstructive pathology].

Strongyloides stercoralis infection was hardly seen in Spain until a few years ago but has recently been shown to be fairly common in some geographic areas. In the respiratory tract this germ can cause acute bronchospasms that make diagnosis difficult, particularly in patients with underlying bronchial disease. To determine if curing S. stercoralis infection is accompanied by clinical and functional improvement in patients with bronchial obstruction, we studied the evolution of 22 infected patients: 11 with no bronchopulmonary disease and 11 with chronic airway obstruction or asthma. The following variables were assessed in both groups at the moment of diagnosis of infection and four months after cure: levels of eosinophils and total serum IgE, respiratory symptoms, steroid doses and spirometric parameters. After four months we observed a significant decrease in eosinophil (16 versus 5%) and IgE (1,600 versus 770 IU/ml) levels in both groups. The number of bronchospasms and daily steroid doses required decreased in the group with bronchial disease. No significant differences were seen in spirometric parameters, however. The improvement in respiratory symptoms, blood parameters and need for medication leads us to believe that airway inflammation decreases after the infection has been eradicated, in spite of the lack of improvement in bronchial obstruction.

[Large-cell lung carcinoma producing chorionic gonadotropin hormone: the difficulty in its differential diagnosis from choriocarcinoma].

We describe a patient with giant cell carcinoma with ectopic production of chorionic gonadotrophin hormone (CGH). This entity is compared with choriocarcinoma, given that the immunologic, histologic and chemical similarities between the two neoplasms can make their anatomic and pathologic differential diagnosis difficult. Clinical examination, response to treatment and CGH blood levels are the criteria for differentiation.

[Contribution of the bronchodilator test in the study of bronchial reversibility].

This study sought to determine the optimum dose of salbutamol and the most useful method for calculating bronchodilator response. Changes in FEV1 after inhalation of 3 doses of salbutamol 200 micrograms were measured in 150 adults (64 healthy individuals, 18 with rhinitis, 53 with asthma and 15 with bronchitis). Bronchodilator response was calculated by 4 different methods: absolute value, percent change form baseline FEV1, from theoretical value and from weighted value. Significant differences in response were observed among the various methods of assessment. Patients with asthma and bronchitis showed the greatest response to salbutamol and their results were used to analyze the usefulness of the reversibility indices. The index that discriminated best was percent of theoretical reference value, although the sensitivity of this index was low and specificity varied from 0.73 to 1 depending on the cut-off point used. This index of reversibility along with absolute value proved to be the least dependent on baseline FEV1. We conclude that bronchodilator response is best assessed by calculating changes in FEV1 in relation to a theoretical reference value. This bronchomotor test, however, does not adequately assess patients with asthma and bronchitis.
