[Sports-related maxillofacial trauma in young patients].

314 young patients with sports-related maxillofacial trauma were classified into 34.7% facial fractures, 35.9% dentoalveolar trauma and 28.4% soft tissue injuries. In the alpine regions the distribution of fractures by aetiology is dominated by skiing accidents. 43% of the midface fractures are due to fractures of the zygomatic bone and arch. Children up to ten years are more prone to dentoalveolar trauma. Opportune preventive measures are recommended.

[AIDS--mucous membrane manifestations].

In the course of the infection with the human immunodeficiency virus (HIV), we frequently observe disorders of the mucous membranes and, occasionally, they present the first manifestation of HIV-induced immunodeficiency. Like in other organs, opportunistic infections and malignant tumors prevail as a result of the impaired immune system. Opportunistic infections are characterized by frequency (candidiasis), aggressive expansion, persistence, frequent recurrences, and resistance to therapy (gingivitis, parodontitis, herpes simplex, warts). Oral hairy leucoplakia is considered a specific lesion of HIV infection. Malignant tumors, such as Kaposi's sarcoma, non-Hodgkin's lymphoma, and squamous cell carcinoma, may cause marked morbidity in AIDS patients; occasionally, the clinical picture of Kaposi's sarcoma and non-Hodgkin's lymphoma is rather uncharacteristic. Other manifestations on the mucous membranes may arise in association with systemic reactions, such as drug eruptions, thrombocytopenic purpura, or acute HIV infection. The etiology of still other lesions of the mucous membranes (e.g. chronic recurrent ulcers, xerostomia, disorders of pigmentation) is incompletely understood. The awareness of these disorders of the mucous membranes in HIV infection is of diagnostic, therapeutic and epidemiological importance.

Carcinoma of the oral cavity: on the prognostic significance of the primary tumour site (by levels and areas).

The prognostic significance of primary tumour site in carcinomas of the oral cavity was investigated in a series of 585 cases. For the subsamples (levels and areas of oral cavity) studied, the numerical distribution of TNM categories, life tables and life table comparisons were computed. This produced the following results: Given an identical extension and analogous metastazising rate, there is no computationally demonstrable difference in prognosis between primary tumours sited at different levels and areas of the oral cavity. The exception are the T1Nx categories, for which a difference exists between precanine and retromolar sites. These results should be re-examined on the basis of a larger series.

TNM-classification of carcinomas of the oral cavity-efficacy of clinically available data (TN).

Using adequate number of cases, the influence of the spread of primary tumour and the degree of regional metastasis on prognosis were investigated. Assuming a practicable classification as a prerequisite for clinico-therapeutic cancer research, experience has shown that the assessment of the spread of primary tumour alone does not suffice for the establishment of comparable homogenous data. The investigation on the importance of the degree of regional metastasis has shown, above all, that the percentage of N3-metastasis within the T-groups contributes essentially to the fact that these show a marked difference in their prognosis. It would therefore appear necessary also to examine the importance of other clinically accessible data in the assessment of prognosis. Only then could we be in a position to judge whether, and to what extent a clinically practicable classification and integration into special groups is possible on the basis of clinically available data. The inclusion of more clinics in the joint investigation is encouraged.
