[Diagnosis of herpes simplex diseases].

The diagnosis of herpes simplex diseases will be made on ground of the typical clinical symptoms in more than 90% of all cases. A very easy additional procedure is the Tzanck test. If possible, immunofluorescent microscopy and electron microscopy of negatively stained virus particles may be helpful. Remaining questions should be solved by further virological examination in special laboratories. Information about sampling and shipment of the diagnostic material (vesicle fluid, swabs from mouth and genital ulcers, blood etc.) should be obtained prior to collection.

Oncornavirus-like particles in human skin cancers.

A high-molecular-weight RNA encapsulated with an RNA-instructed DNA polymerase in particles possessing the density characteristic of the RNA tumor viruses has been detected in 13 out of 14 human malignant melanomas. The [3H]DNA synthesized by these particles in an endogenous reaction hybridizes to RNA extracted from the human melanoma particulate structures, but not to RNA from normal skin. Similar particles containing RNA and enzyme have been found in basal cell and squamous cell carcinomas of the skin. The RNA of the melanoma particles is easily distinguishable by hybridization from the RNAs found in the particles of the basal and squamous cell carcinomas.

[Acryronitril as a contact allergen].

A case of allergic contact dermatitis following the use of a Plexidur finger splint is reported. The allergen was acrylonitrile, one of the original constituents of the polymer Plexidur.
