Acute hand infections and surgical treatment.

Hand infection is a common and frequent problem encountered by surgeons in their outpatient clinics. The causes are varied, ranging from trauma to surgical intervention and to the spread of infection from elsewhere on the body. The causative agents of infection are also varied, and although bacteria are the most common ones, viruses, fungi, and, of course, the problem of diagnosis after parasite infestation as well as rare causes of infections must also be considered.

[Hydrophilic gel matrix tablets for oral administration of drugs].

Matrix tablets with a dispersed active ingredient are the simplest concept in the design of dosage forms with modified drug release. If they contain a swelling polymer as an auxiliary substance, the release from these systems, after initial liberation of a portion of the active ingredient from the surface, takes place by diffusion, erosion, or a combination of both mechanisms in dependence on the solubility of the contained active ingredient. Although hydrophilic matrix tablets have become a well-tried and widely used dosage form with retarded effects, their research continues and new auxiliary substances and their combinations are being tested.
