'Water-test': a simple method to assess sperm-membrane integrity.

The functional integrity of the membrane of sperm from semen samples collected from 10 fertile men (Group A) and from 50 infertile men (Group B) was assessed by studying the swelling reaction of sperm when suspended in a medium of distilled water ('Water-test'). The results were correlated with routine semen-analysis and with the results of Eosin-Y staining. The mean values for the 'Water-test' were significantly different (P less than 0.01) between Groups A and B (84.8 +/- 3.5 versus 70.9 +/- 13.3, respectively). No significant correlations were observed in either Group A or B, between values for the 'Water-test' and values for the sperm count, the percentage of sperm with normal morphology and the percentage of motile sperm. There was a good correlation in both Group A (r = 0.86, P less than 0.01) and Group B (r = 0.92, P less than 0.01) between values for the 'Water-test' and those for the Eosin-Y test. These results indicate that the 'Water-test' is a simple and reliable test for evaluating sperm membrane integrity.

[Thucydides' syndrome].

The epidemic that broke out in Athens during the Peloponnesian War was certainly one of the biggest disasters described in the history of mankind. In the past numerous scholars have unsuccessfully attempted to identify the aetiological agent of the plague. Two new hypotheses have also recently been put forward but do not fully clarify all the diverse aspects of the plague whose aetiopathogenesis apparently remains a still unsolved problem.

[The echotomographic assessment of the thyroid bed in thyroidectomized subjects].

This study was aimed at evaluating the US anatomy of the postoperative thyroid bed. Fifteen normal patients (group A), 25 thyroidectomized patients (group B), and 2 patients with thyroid agenesis (group C) were evaluated by means of high-resolution real-time US. The examinations were performed with a 7.5 MHz small-parts linear transducer on the transverse, longitudinal, and oblique planes. Twenty-one patients in group B underwent subtotal thyroidectomy for multinodular goiter, 2 patients underwent an almost total thyroidectomy for Basedow's disease, and 2 patients were submitted to total thyroidectomy for papillary carcinoma. The most typical finding observed in group B was the close apposition of both carotid artery and jugular vein to the trachea. This finding was not observed in the patients in group C. No clear identification of parathyroid glands and of laryngeal nerves was possible in the patients in group B.
