Duplex ultrasonography detects clinically significant anomalies of penile arterial vasculature affecting surgical approach to penile straightening.

Objectives: To determine the frequency of aberrant penile arterial anatomy in men with Peyronie's disease (PD) and the potential impact on the surgical approach to penile straightening.

Methods: A retrospective analysis of 63 consecutive men undergoing penile duplex ultrasonography in preparation for penile straightening surgery was performed. They were compared with a group of 61 men with erectile dysfunction (ED) undergoing penile duplex ultrasonography during the same period.

[Morphology and diagnosis of the oral protozoans Trichomonas tenax and Entamoeba gingivalis using the Giemsa-Romanovsky stain].

In the microscopic diagnosis of Trichomonas tenax and Entamoeba gingivalis is the technically and time not demanding native preparation of a culture, in which both protozoans can be detected according to their typical motility, determining. In the permanent preparation of the culture stained according to Giemsa-Romanovsky, which has also documentary character, are all of the characteristic cell organelles stainable, enabling so their detection without their typical motility. Staining according to Giemsa-Romanovsky is technically simple and not time consuming, not very laborious, low cost and the coloration is permanent, that means optimal for the diagnostic of oral protozoans in permanent preparations.

[Occurrence of the protozoa, Entamoeba gingivalis and Trichomonas tenax in the mouths of children and adolescents with hyperplastic gingivitis caused by phenytoin].

The oral protozoa Entamoeba gingivalis and Trichomonas tenax do not occur in small children and are rarely found in older ones. In adolescents their occurrence rate keeps increasing with age. They parasitize in an oral cavity changed by inflammation, yet also in a healthy mouth.

[The role of Toxoplasma gondii in the etiology of chronic tonsillitis in children].

Toxoplasma gondii is known to have an affinity to lymphatic tissue. A series of 506 children with chronic tonsillitis were examined serologically for toxoplasmosis by means of CBR, IIR and ELISA. In 7.

[The role of Toxoplasma gondii in the etiology of chronic tonsillitis in children].

Toxoplasma gondii is know to have an affinity to lymphatic tissue. The authors studied whether after infection of the child's body T. gondii does or does not determine the chronic course of tonsillitis.
