[Semeiotic flowmetry in complex varicocele].

The Authors report on their specific experience on the funicular Doppler veocimetry, regarding the varicocele. In particular we enhance the semeiological spects of the C.W. Doppler velocimetry in the sub-clinical varicocele, in the bilateral one and in the characterization of the spermatic and cremasteric refluxes, and of the external pudenda vein. The Authors stress the utility of the definition of the amount of the reflux, so achieving an integration with the existing classification by degrees, that as it is now days expressed, it seems, to regard the elapsed time and the quantity of reflux caused by the Valsalva manoeuvre. In the practical velocimetry those elements have not been proved to have a parallel increment. Lastly, we report on some cases of veno-spermatic refluxes, uniquely observed in the clynostatism, along with a missing orthostatism. Moreover the Authors believe that some of these hemodynamical consideration could be revisited.

Histochemical study of human nasopharyngeal epithelium by horseradish peroxidase conjugated lectins.

This study proposes a simple method for assessing whether non-respiratory epithelia of the nasopharynx (i.e. cuboidal, squamous) represent a modified differentiation from the normal pseudo-stratified lining, or whether they possess common characteristics suggesting they are just in a different morphological stage. Peroxidase-labelled lectins were used, since they detect sugar residues of membrane glycoconjugates which play an important role in cell differentiation. Biopsies were taken from healthy controls and from patients affected by upper airway inflammation of varying degree and duration. While pseudostratified and cuboidal epithelia possess similar histochemical characteristics, squamous epithelium has a different behaviour; in particular it is the only type to show intense reactivity to Lotus tetragonolobus lectin (LTA). This would seem to indicate that squamous epithelium is in a different state of differentiation, possibly suggesting dysplasia. Lectins may be valuable both in morphological studies and in the clinical evaluation of airway epithelia.

[Antithyroid antibodies and endemic goiter].

Relationship between thyroid autoantibodies and endemic goiter have been studied in 164 subjects from three different areas of endemic goiter: 91 patients and 31 healthy controls from Central Sardinia, 23 patients from Northern Latium, and 19 patients from Southern Latium. In subjects with endemic goiter from Sardinia higher levels of thyroid autoantibodies were present as compared to the healthy controls; microsomal fraction autoantibodies titer was higher than antithyroglobulin autoantibodies. In subjects from the two other endemic goiter areas the antimicrosomal and antithyroglobulin autoantibodies were absent, with the exception of one patient with basedow's goiter. It is suggested that some of the areas classified as positive for endemic goiter are indeed characterized by an extensive genetic predisposition to lymphocytic chronic thyroiditis complicated by nodular goiter.
