    Notes: A case with oral Kaposi's sarcom (KS) is reported that regressed during therapy with Zidovudine (AZT) which was started 5 months after the first dermal and oral tumours were noted. After 6 months of treatment the absolute number of T-helper cells had increased from 54/μl to 232/μl and the ratio of T-helper to T-suppressor cells from 0.15 to 0.3. During the same time the lesions of KS on the gingiva, uvula and the body as well as the face disappeared. The lesion of KS on the hard palate regressed.

    Notes: Abstract. Sprague-Dawley rats received intragastrically a single dose of 226Ra or 224Ra once weekly for 21 weeks. During this period the animals of both groups were thus exposed to comparable doses. After 12 weeks, a shortening of the maxillary incisors was observed, and this progressed during the course of the 55–week experiment. Radiologically, a loss of pulpal transparency and an apical irregular opacity in the maxillary incisors were demonstrable. Histologically, dysplastic changes of the maxillary incisors and multiple resorptions at the cemento-enamel junction of the molars were seen. The observed alterations were more pronounced in the 226Ra group than in the 224Ra treated group. The experimentally induced resorptions were comparable to those observed in patients who had incorporated 224Ra or 226Ra. Clinical, radiological, histological, γ-spectrometrical, and autoradiographical findings, as well as dose-estimations, are described.

    Notes: The ultrastructure of tumour cells and tumour droplets (TD, non-calcified amorphous masses) was studied in three cases of AOT using freshly prepared tissue. The fine structure of the epithelial tumour cells (cell type I-III) corresponded to that of earlier descriptions. The extracellular location of TD was clearly demonstrated. TD were of varying, sometimes bizarre, configuration. Some TD showed a homogeneous matrix; however, in addition most revealed electron-dense plaques. At high magnification, homogeneous types of TD showed only tubular elements; all others revealed granulo-tubular structures. The tubular elements were arranged concentrically. The nature of the TD is discussed and compared to former interpretations. From the present ultrastructural findings, it appears that the TD most probably represent some form of enamel matrix and as such may be considered a type of pre-enamel. Further studies are needed to elucidate the complex structure of the TD-material so characteristic of the AOT.

    Notes: A total of 102 rural Cambodian women with a mean age of 60×8.5 years (range 39 to 80 years) who chewed betel quid were examined for oral mucosal lesions, in particular betel chewer's mucosa. The average duration of betel quid chewing was 15.5 × 12.8 years. The average number of daily betel quids was 5.4 × 2.9. Forty women (39.2%) used betel quids overnight. Thirty-eight (37.3%) did not show any oral mucosal lesion. Sixty-two (60.8%) showed beiel chewer's mucosa. Homogeneous leukoplakia was found in three women (2.9%). Out of 130 sites affected by chewer's mucosa, the buccal mucosa was the most frequently involed (n= 68). In thirty-two subjects (31.4%) more than one location was affected. The presence of a lesion was significantly associated with the duration of the habit (P 〈 0.01) and the number of betel quids per day (P 〈0.001). Betel chewing seems to be prevalent in elderly Cambodian women, while younger people do not seem to have taken up this habit. The risk for oral cancer in the Cambodian population is presently unknown.

    Distribution of cytokeratins in oral cytological smears of HIV-infected patients (1992)

    Notes: Cytological smears (CS), taken from the lateral border of the tongue of HIV-seropositive patients (HIV +) (n= 34) and of seronegative controls (HIV -) (n= 16), were examined by means of immunocytoychemistry (APAAP) for the distribution patterns of different cytokeratins and MHC class II antigens. Compared with HIV- patients in CS of HIV-infected patients cornification associated cytokeratins 10/11 were increased, while the number of keratinocytes positive for cytokeratins 13/16 was comparable in both groups. Expression of simple epithelial cytokeratins 19, rarely observed in CS of HIV- patients, was a frequent findings in CS of HIV+ patients. Keratinocytes positive for MHC class II antigens were observed in CS of 12/34 HIV +, while all control CS were negative. In the group of HIV + patients no correlation was found between the clinical presence of HL and the expression of cytokeratins or class II antigens. The altered distribution of cytokeratins may reflect local responses to proliferative stimuli or local inflammation due to the presence of microbial antigens or may occur as a general unspecific reaction in the setting of systemic viral infection. This non-invasive technique seems to be a valuable tool to determine the proliferation rate of oral epithelial cells.

    Notes: The macro- and microanatomy of the marginal tongue mucosa were studied. Tissues were harvested from 12 individuals at autopsy. Random sections from six different locations along the margin and serial sections representing three defined section planes to the margin of the tongue were evaluated. Vertical, parallel mucosal folds alternating with shallow grooves were a characteristic macroscopical finding on the lateral border of the tongue. The mucosa presented a non-keratinized epithelium with PAS-positive, lightly stained spinous cells and no or slight inflammatory reaction in the connective tissue. Changes in the epithelium mimicking hyperplasia, acanthosis, keratin projections, and focal parakeratosis could be produced by changing the direction of tissue sectioning. The macro- and microscopical parameters recorded in normal marginal tongue mucosa are among others included in criteria for diagnosing oral hairy leukoplakia. The results emphasize the importance of a thorough knowledge of the normal anatomy of a mucosal site to arrive at reliable diagnostic criteria.

    Notes: Twelve biopsies of clinically normal oral mucosa taken from HIV seropositive patients have been investigated by means of light- and electron microscopy. Vascular abnormalities were found in all biopsies, regardless of the clinical stage of the HIV infection. In particular slit-like vascular channels, sparseness of intercellular junctions and swollen, protruded endothelial cells with an increased quantity of Weibel-Palade bodies were noticed. These findings were similar to those described in lesions of early stage Kaposi's sarcoma.

    Notes: Ten teeth of betel chewing P'wo Karen, a hilltribe group of northern Thailand were available for this morphologic study. The structural composition of the black layer on these teeth was studied by light microscopy, microradiography and by electronmicroscopy. Principally, the black layer on the teeth of betel chewers was identical with subgingival calculus which had been colored by specific polyphenols contained in the betel nut. However, a pellicle-like layer forming initially on enamel crystals was also observed, from the morphologic aspect of the black layer a specific anticariogenic property cannot be attested. Further studies on the chemical composition of this black layer may elucidate its probable anticariogenic and its carcinogenic properties relative to oral suhmucous fibrosis.

    Notes: Monoclonal antibodies which react against T-cell subpopulations and Langerhans' cells were used to examine the phenotype of immunocompetent cells in oral lichen planus. Immunomorphologically, the stromal infiltrate of this condition considerably resembled the delayed type of immune reaction. Although all subpopulations of immunocompetent cells were present in the stromal infiltrate, Langerhans' cells (OKT-6 positive, HLA-DR positive) and suppressor/cytotoxic T-lymphocytes (OKT-3 positive, OKT-4 negative, OKT-8 positive, HLA-DR positive) predominated. Our immunohistological findings support the suggestion that aggregations of T-lymphocytes are responsible for the cytotoxic processes which occur within the squamous epithelium in oral lichen planus.
