摘要:

Numerous papers on epithelial jaw cysts have appeared in the decade since the publication in 1971 of the WHO histological classification of odontogenic tumours, jaw cysts, and allied lesions. Despite clarification of certain cyst varieties no major revisions are necessary. The following minor modifications are proposed. In the developmental odontogenic group, the terms keratocyst and follicular are preferred to primordial and dentigerous. The alveolar cyst of infants is categorised separately from the gingival cyst of adults. The developmental lateral periodontal cyst is included as a distinctive new type. In the non‐odontogenic group the globulomaxillary is deleted as a unique entity, whereas the midpalatal eyst of infants is a new inclusion. To the inflammatory category are added the inflammatory follicular and inflammatory lateral periodontal varietie

摘要:

Calcinosis, the process whereby calcium salts are deposited in soft tissues, may be idiopathic, metastatic or dystrophic. Metastatic calcinosis develops in a variety of systemic diseases characterized by cither hypercalcemia, hyperphosphatemia, or both. Dystrophic calcinosis refers to calcification of previously damaged or necrotic tissue. It may be found accompanying inflammatory or degenerative conditions and is frequently associated with connective tissue diseases. When pathologic calcification is widespread, an attempt must be made to determine the underlying cause. A case is presented in which there was multifocal calcium deposition in soft tissues, including an intra‐oral site. The patient also exhibited severe arthritis, sicca syndrome, focal alopecia and vitiligo. In view of this clinical spectrum, one of the “collagen diseases” (dermatomyositis, lupus erythematosus, rheumatoid arthritis, and scleroderina) was suspected as a predisposing factor for disseminated calcinosis. When diagnostic workup failed to reveal a specific connective tissue disease, it was concluded that “undifferentiated connective tissue disease” was responsible for dystrophic c

摘要:

The dental follicle is a loose connective tissue layer that surrounds the developing and erupting tooth. The follicle is necessary for tooth eruption in dogs and specific cellular changes occur in the follicle at the onset of tooth eruption, in particular, within the coronal region of the follicle next to areas of subsequent bone resorption there is an increase in mononuclear cells which have the ultrastructure features of monocytes and contain specific granules characteristic of preosteoclasts. The follicle has an extensive microvasculature and monocytes are often seen adjacent to capillaries and venules. Monocytes increase in number in direct proportion to the increase in osteoclasts that form the eruption pathway and decrease in number as soon as this activity is completed. It is postulated that monocytes enter the follicle from the microvasculature and then migrate to the walls of the bony crypt to participate in the formation of the eruption pathway.

摘要:

A retrospective analysis of 33 eases of maxillary sinus cancer seen at R.P.M.I. between 1970 and 1979 was performed. The age of the patients ranged from 18–88 years, with a median age of 60.3. The male to female ratio was 2:1.3. Twenty‐seven (81.8%) of the cases were squamous cell carcinomas. Of the 33 cases, there were no cases in Stage 1, 2 cases in Stage 2, 8 and 23 in Stages 3 and 4, respectively. The 5‐year survival among the patients who were available for a long‐term follow‐up was 36.47, (8 of 22). The 5‐year survival was best for Stage 3 disease (75%) and Stage 4, without local and/or distant metastasis (57.14%). No patient with metastasis lived for more than 3 years. While poorer diagnosis could he related to the degree of local involvement and presence of metastasis, it could not be related to site of involvement, previous treatment, histological findings or delay in diagnosis. Correlation of treatment with prognosis is difficult because selection of treatment is based on a variety of factors, including stage of disease and patient acceptance of treatment. Of the 4 patients treated with surgery alone, all 4 survived for 5 years. Of the 8 patients treated with combined surgery and radiation, 4 survived for 5 years and 2 died without evidence of tumor before 2 years. Other treatments were far less

摘要:

Submandibular glands are a target organ of thyroid hormones. This study examined the effects of hypothyroidism on the biochemical characteristics of these glands in the nil. There were no effects on the neutral sugar and DNA contents. However, soluble protein concentrations (μg/mg wet weight) were significantly decreased and sialic acid concentrations (μg/mg soluble protein) were significantly elevate
