This paper reviews the current concepts of mycology and candidal infections as they relate to the oral cavity. Proposed classification for the presentation of oral candidosis is outlined as are examples of these topical infections, such as erythematous, pseudo-membranous and hyperplastic candidosis, as well as angular chelitis and median rhomboid glossitis. The diagnosis and principles of management of oral candidosis are discussed, the therapeutic agents available for the management of these infections are presented and a treatment protocol for the management of patients with oral candidosis is given. 相似文献

The advent of the human immunodeficiency virus infection and the increasing prevalence of compromised individuals in the community due to modern therapeutic advances have resulted in a resurgence of opportunistic infections, including oral candidosis, which is by far the most common oral fungal infection in man. Broad-spectrum antibiotics used in the treatment of a wide range of disease conditions have also been attributed as a predisposing factor of oral candidosis. In this mini review we discuss the research findings on the relationship between antibiotics and oral candidosis and possible mechanisms of pathogenicity following such therapy. 相似文献

Autopolymerizing acrylic resin supplemented with 10 per cent miconazole nitrate was tested as a treatment for palatal candidosis as induced by Shakir et al. (1981) in the Wistar rat It was found that by fitting rats with appliances supplemented with 10 per cent(w/w) miconazole in the polymer powder, palatal candidosis could be prevented, and previously infected animals were cured after therapy for one month Rats fitted with supplemented appliances showed no adverse side-effects and tended to gain weight more rapidly than animals with unsupplemented appliances. 相似文献

The number of immunocompromised patients is increasing because of iatrogenic immunosuppression and HIV infection. Most have T lymphocyte defects and are prone to develop persistent and severe fungal and viral infections. Oral candidosis and peri-oral herpes simplex infections are particularly common. Other oral lesions may be seen: mouth ulceration is common and periodontal health is impaired. 相似文献

A model of oral candidosis was developed in order to investigate histologic and microbiologic aspects of this host-parasite interaction under controlled experimental conditions. Normal adult CD-1 mice were inoculated by the topical application of 10(8) Candida albicans blastospores, and oral colonization was monitored by the quantitative culturing of saliva samples and of digested oral mucosa. Tissue sections of the mucosa were examined in a kinetic study ranging from 2 h to 13 days postinoculation. We report here that oral colonization by C. albicans can be induced in normal adult mice without the use of any compromising agent and that the animals recover from this mucosal infection following a reproducible pattern. Temporal analysis of the oral histopathology showed that distinct patterns of inflammation are associated with particular stages in the development of the infectious foci. This experimental model offers a means of further investigating the host-parasite interactions involved in the onset and development of oral candidosis. 相似文献

Epithelial mitotic activity during the induction of palatal candidosis in the Wistar rat 总被引:1,自引:0,他引:1
Palatal candidosis was produced in 15 Wistar rats by fitting them with an acrylic appliance that covered the palatal mucosa and simultaneously inoculating this site with Candida albicans 3091 (serotype A). A further 15 rats were fitted with the appliance only. Five animals in each group were killed at 1, 2 and 4 weeks, 4 X 5 h after being injected with vinblastine sulphate, as were 5 normal control animals at the start of the experiment. Palatal mucosa was dissected free, fixed, sectioned and stained prior to counting the number of arrested mitotic figures in the basal epithelial layer and measuring the mean thickness of epithelium. The results were expressed as the number of mitotic figures per 1000 basal cells, per unit length of basement membrane and per square millimetre of epithelial surface. After an initial reduction in thickness, the palatal epithelium in both experimental groups became thicker than that of normal control animals, more markedly so in the animals infected with Candida albicans. Similar patterns of mitotic activity were found regardless of the reference unit used as a basis for the calculations. An initial decrease in both experimental groups was followed by a sharp and significant rise, again being more marked in the animals infected with Candida albicans. 相似文献

Oral candidosis is an increasingly important disease that affects a significant percentage of the population. Traditionally known as an opportunistic pathogen, the broader clinical scope of oropharyngeal candidal infections is now being recognized. The clinical and historical features of 100 patients referred for diagnosis and management of candidosis have been reviewed. The age, gender, chief complaint, medical history, medications, and clinical findings have been noted. A wide range of clinical signs and symptoms, and the rationale behind the topical and systemic antifungal therapies provided to this patient population, are discussed. 相似文献

A 62-year-old woman sought treatment for a red macule in her hard palate. Examination of the oral cavity revealed an ovoid-shaped erythematous macule on the right side of the hard palate. The patient was edentulous and used a poorly adapted maxillary denture. The initial diagnosis was chronic atrophic candidosis and trauma; however, when the lesion did not heal following removal of the prosthesis and application of topical antifungal medication, an incisional biopsy was performed, resulting in a final diagnosis of low-grade mucoepidermoid carcinoma. The patient was referred to a head and neck surgeon and the tumor was excised. 相似文献

The advent of the human immunodeficiency virus and the increasing prevalence of immunocompromised individuals in the community have resulted in a resurgence of opportunistic infections, including oral candidoses. Despite the availability of a number of effective antimycotics for the management of oral candidoses, therapeutic failure is not uncommon. Further, the presence of many clinical variants of oral candidosis, both new and old, may confound the unwary clinician and complicate its management. These problems have been partly circumvented by the introduction of the triazole group of antimycotics, which initially appeared to be highly effective. However, an alarming increase in organisms resistant to triazoles has been reported recently. In this paper we provide an overview of clinical variants of oral candidosis. A second paper will discuss recent advances in the usage of antimycotics in the management of this condition. 相似文献

Certain systemic conditions and/or defects in the immune system may predispose the host to oral candidal infection and the commonest form of oral candidosis is candida-associated denture stomatitis. Until recently there has been controversy concerning the aetiology of the disease. Although some earlier investigators linked denture stomatitis with trauma or bacterial infection, others had isolated Candida albicans from the mouths of patients with the condition. Current studies indicate that denture stomatitis lesions are associated with the detection of candida species while other factors such as denture hygiene, trauma, systemic diseases and deficiencies of the immune system may be involved. 相似文献
