Several sperm retrieval techniques are available for use on azoospeermic men. Comparisons between spermatozoa retrieved from the testicles and epididymis in relation to pregnancy and miscarriage rates are not well established. ⋯ Although pregnancy rates were similar when the intracytoplasmic sperm injection was performed with spermatozoa retrieved from the testicles and epididymis, the use of testicular spermatozoa yields a significantly higher miscarriage rate. It is possible that the higher miscarriage rate seen in patients using spermatozoa retrieved from the testicles is linked to high genetic sperm abnormalities.

Pulmonary thromboembolism is the third most frequent cause of morbidity and mortality among acute cardiovascular diseases. The incidence of pulmonary embolism in necropsies has remained unchanged over the last few decades. Cardiac diseases, neoplasia, trauma, recent surgery and systemic diseases are important predisposing clinical conditions. The relationship between male and female sexes is estimated at 1.24. Various studies have shown an increase in morbidity in spring and autumn. There is great difficulty in precise anatomopathological diagnosis in relation to the localization of the emboli in the pulmonary vessels, although they are preferentially located in the right lung and lower lobes. ⋯ Over the period of this study, it was observed that there was a reduction in the incidence of pulmonary thromboembolism, which was probably due to the increase in prophylactic measures over the last few decades. Nonetheless, lethal thromboembolism predominated in frequency, probably because of the abrupt onset of a condition of attack across a large area of the lung, lack of clinical suspicions and consequently a lack of early diagnosis, and delay in instituting fibrinolytic therapy in the cases with hemodynamic repercussions or a large number of lung segments affected.

Patients receiving adjuvant chemotherapy for breast cancer have a tendency to gain weight. This tendency has determining factors not completely defined and an unknown prognostic impact. ⋯ Women with breast cancer undergoing adjuvant or neoadjuvant chemotherapy gain weight, whereas metastatic cancer patients will probably lose weight during palliative chemotherapy. Further studies are needed in order to evaluate the prognostic significance of weight changes during chemotherapy.

It has been demonstrated that children exposed to parents who smoke have more respiratory infections and asthma. ⋯ The presence of respiratory infections and asthma was associated with atopic parents but not with the presence of two or more positive skin tests for allergies among the children. Also, respiratory infections and asthma attacks were not associated with smoking parents or with the length of time spent by the children at school.

MIDAS was developed as a fast and efficient method for identification of migraine in need of medical evaluation and treatment. It was necessary to translate MIDAS, originally written in English, so as to apply it in Brazil and make it usable by individuals from a variety of social-economic-cultural backgrounds. ⋯ MIDAS translated to Brazilian Portuguese was a useful tool for identifying severe cases of migraine and of transformed migraine in a working environment. The workers did not consider MIDAS to be difficult to answer. Their high level of voluntary participation demonstrates that this medical condition was of real interest among the workers, whether they were sufferers or not.
