ABSTRACT
Currently, methods of modern imaging are increasingly assuming a predominant position in diagnostics and therapy. Larger and larger amounts of sensitive data and information are generated, processed and--frequently with inadequate protection--transmitted through generally accessible networks. The Internet is used especially intensively as a medium for transporting digital data; at the same time, protection of sensitive data is frequently neglected to a high degree by medical professionals. The present contribution is therefore intended to provide an overview of currently valid standards and legal regulations, as well as suitable encoding methods relevant for the dental practice.

Trichoadenoma of Nikolowski is a rare, benign, well differentiated, slowly growing tumor of the hair follicle which was first described in 1958 by Nikolowski. 26 cases reported in the literature since then and our seven cases show the following features: a tumor of adults, mostly in the face (57.5%) or buttocks (24.2%), size in general 0.5-1.5 cm, no sex preference. According its morphological differentiation, trichoadenoma is situated between a trichofolliculoma and a trichoepithelioma. The clinical appearance is, misleading, suggesting the diagnosis of basal cell carcinoma or epidermal cyst.

The present study deals with 81 primary adenocarcinomas of the uterine cervix diagnosed and treated in the departement of gynecology and obstetrics of the University of Zürich from 1950 through 1977. Clinical and morphological data such as patients age, character and duration of symptoms, clinical and anatomical stage, histological differentiation of the tumor and therapy were recorded and analysed in relation to patients survival. Of all these factors the stage of the tumor at time of diagnosis proved to have the highest prognostic significance.
