Hereditary angioedema: uncomplicated maxillofacial surgery using short-term C1 inhibitor replacement therapy.

We report on the successful use of a pasteurized C1 inhibitor (C1-INH) concentrate during dental surgery of a patient affected by hereditary angioedema. The patient recovered fully without complications or side effects. Within 30 min, the first 1,000 U of C1-INH concentrate raised C1-INH concentration from 19 to 55% and function from 40 to 90% of the normal mean.

[Efficiency of systemic prophylatic antibiotics in the surgical removal of lower widsom teeth].

The efficiency of prophylactically given systemic antibiotics was examined in a double-blind study on 142 patients on an ambulatory basis. It was found that the application of antibiotics do not significantly lower the rate of postoperative infections after the surgical removal of lower third molars.

Hypernephroma metastatic to the palatine tonsils.

Review of the literature discloses 76 cases of carcinoma metastatic to the palatine tonsil. Of these cases reported or mentioned, 51 were detailed sufficiently or occurred frequently enough to allow analysis. We add two new cases of hypernephroma, and also study the courses of patients with primaries of the stomach, breast, lung and melanoma and seminoma.

Dose-response hyperplasia and neoplasia from feeding N-2-fluorenylacetamide (2-FAA) to BALB/c mice for varying time intervals.

Hyperplasia induced by N-2-fluorenylacetamide requires the continuous presence of the chemical for its maintenance. Feeding the chemical at levels of 8 to 86 ppm results in a dose-response related urinary bladder hyperplasia and, after 9 to 12 months, in bladder neoplasia at the higher dose levels. Neoplasia of the lungs, liver, parotid gland, lacrimal gland, harderian gland, and submaxillary gland was also observed.

[Functionally stable osteosynthesis of the mandible by means of an excentric-dynamic compression plate. Results of a follow-up of 25 cases].

The stability of internal fixation is enhanced by axial compression on the fracture ends. If internal fixation of the mandible is achieved by a compression plate at the lower border of the mandible (compression side), distraction of the fracture ends on the occlusal side occurs which has to be counteracted without damaging the roots of the teeth on the occlusal side (traction side) or without damaging the inferior alveolar nerve. From experiments on models it was seen that an acceptable solution to this problem is given by the use of the combined compression plate and tension band plate or the "Excentric Dynamic Compression Plate" (EDCP).
