Temporomandibular arthropathies: A retrospective study with histopathological characteristics.

Background: To investigate the incidence of temporomandibular arthropathies diagnosed in a university center and to describe their histopathological characteristics.

Material And Methods: Temporomandibular arthropathy cases with corresponding slides were selected from an oral and maxillofacial surgical pathology service. Cases of exclusively articular disc disease were not included.

[Retrospective multicenter study on carcinomas of the lips and oral cavity. The role of multiple malignancies].

In a retrospective multicenter study the role of multiple cancer has been assessed in 2481 patients with carcinomas of the lips and oral cavity. In 3.2% of the cases the malignancies developed outside the maxillofacial area.

[Multicentric retrospective study on the carcinoma of lips and oral mucosa. Analysis of coherence between pre- and posttherapeutical categories of classification].

The coherence between prae- and posttherapeutical TNM findings had been checked up in a multicentrically registered patient material of 2,481 non-praetreated plate epithelium carcinomas of the lips and oral mucosa. Whereas the extension of the tumour has in the main been the same, the findings on lymph nodes had a trend showing essential deviations. In a two-dimensional examination of 851 histologically prepared preparations of lymph nodes, a prognostic relevance acc.

[Initial results of high-dose-rate afterloading treatment of tumors in the head and neck region].

First results of high-dose-rate afterloading therapy in the head-neck area are encouraging. The procedure is not very invasive and is suitable especially for older patients, not tolerating much, who can be hardly submitted another therapeutic method. The limited spatial dose distribution allows a careful treatment of the surrounding tissue in spite of the application of high single doses, however limits the size of tumors too, that the afterloading therapy is possible in (max.

[Results of an analysis of waiting time at a maxillofacial surgery outpatient department of a university hospital].

Waiting periods in public health institutions not only stress the patients and the personnel, but they are also attended by considerable economic disadvantages. For this reason, the waiting periods of patients of a maxillofacial outpatient department in the various examination and treatment stations were analyzed with the help of accompanying leaflets. According to the results obtained, the sequence of examinations and treatments was verified and reorganized with regard to the three main processes: research, medical care, and education and training.

[Use of the intra-alveolar GR (gelatin-resorcinol) dressing after tooth extraction in patients with hemorrhagic diathesis].

The suitability of an intra-alveolar gelatin-resorcinol dressing for controlling bleeding was tested in 118 tooth extractions on a total of 87 patients. Plain advantages of the dressing are: prompt haemostasis (which in most cases avoids hospitalization and substitution therapy), low cost, and easy application. The dressing is not always reliable in controlling bleeding after milk tooth extraction.

[Immunologic studies of lymph nodes in patients with maxillofacial tumors].

Starting from the basic concept that the regional lymph node, due to its important role in the defensive reaction to cancer, has a great value of information, the authors investigated 14 lymph nodes from patients with cancer in the maxillofacial region. The following immunological examinations were performed: T lymphocyte determination by means of the ovine erythrocyte rosette test; B lymphocyte determination by means of the mouse erythrocyte rosette test, with surface immunoglobulin estimation using the direct immunofluorescence technique; quantitative determination of immunoglobulins G, A and M in the lymph node extract. The results demonstrated that the determination of the absolute number of peripheral lymphocytes and of T rosettes as well as the immunoglobulin quantitation are very valuable.

[The orofacial manifestation of various hemoblastoses].

In everyday practice the stomatologist is sometimes confronted with symptoms that are indicative of malignant diseases. For malignant lymphoma, lymphogranulomatosis and myeloic leucosis, as examples, the authors present in tabular form orofacial symptoms such as bleedings, gingival hyperplasia, ulcerations and others, the occurrence of which requires diagnostic assessment.

[Improvement of healing of pedicled skin flaps and free skin grafts (animal experiments)].

A combined therapy in order to improve the healing of dermatoplasties is presented. Epicutaneous application of oxygen is combined with injection of a vasodilating drug. The results from experiments on 25 rabbits showed accelerated healing, smaller necroting areas, and improved circulation in pedicled skin flaps of well as in free cutaneous grafts.

[Experimental studies on the antimicrobial effect of several butylcyanoacrylate tissue adhesives].

It is dealt with the effects of various butycyano-acrylate type surgical adhesives on gram-positive and gram-negative bacterial species. The experimental results show a growth-inhibiting effect on gram-positive germs. Gram-negative germs are not affected.

[Comparative studies on the breaking strength of tissue adhesives of the butylcyanoacrylate type].

Four tissue adhesives of the butylcyano-acrylate type were tested for breaking strength. The addition of dyes and stabilizers results in an increase in breaking strength. Adhesives coloured with an anthraquinone dye and stabilized with SO2 significantly surpass in breaking strength adhesives that are only coloured or stabilized.

[The use of modern documentation methods in dental offices, an analysis of the literature].

The aim of the present paper was to assess, on the basis of an analysis of the relevant modern, national and international literature as available in the GDR, the present state of the introduction of data processing to stomatology and to deduce recommendations for further lines of work.
