1/19. Proliferative verrucous leukoplakia: report of two cases and a discussion of clinicopathology.Proliferative verrucous leukoplakia (PVL) is a recently delineated but poorly recognized form of multifocal leukoplakia that is premalignant and of unproven origin. PVL generally presents as a simple benign form of hyperkeratosis that tends to spread and become diffuse. Although slow-growing, the disease is persistent and irreversible. Clinically, PVL often presents as an exophytic wart-like form of leukoplakia that appears to be resistant to nearly all forms of therapy. PVL of the oral cavity is best-defined as a continuum of oral epithelial disease with hyperkeratosis at one end of a clinical and microscopic spectrum and verrucous carcinoma or squamous cell carcinoma at the other. The microscopic findings associated with PVL are dependent on the stage of the disease and the adequacy of the biopsy. Microscopic findings can be markedly variable. PVL is a clinicopathologic disorder that includes the microscopic entity known as verrucous hyperplasia as a component of its histopathologic progression. This article reports on two cases of PVL, describes the clinicopathology of the disease process, and presents therapeutic and etiologic considerations.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/19. Complete dentures and the associated soft tissues.Some of the conditions of the soft tissues related to complete dentures encountered during a period of 25 years at a university clinic were presented and discussed from the standpoint of the clinical prosthodontist. During this time, over 1,000 denture patients were treated each year. For some conditions, a method of management was offered with treatment by sound prosthodontic principles rather than unneccessary medication. That denture fabrication involves much more than mere mechanical procedures is an understatement. Complete dentures are foreign objects in the oral cavity that are accepted and tolerated by the tissue to a degree that is surprising. As prosthodontists, we can gain satisfaction from the realization that the incidence of oral cancer due to dentures is less than extremely low. At the same time, we must be ever mindful of the statement by Sheppard and associates. "Complete dentures are not the innocuous devices we often think they are." Every dentist must remember that one of his greatest missions is to serve as a detection agency for cancer. The information discussed indicates (1) the need for careful examination of the mouth, (2) the value of a rest period of 8 hours every day for the supporting tissues, and (3) the importance of regular recall visits for denture patients. Robinson stated that while the dental laboratory technician can be trained to aid the dentist in the fabrication of prosthetic devices, his lack of knowledge of reactions and diseases of the oral tissues limits him to an auxiliary role. Complete prosthodontics is a highly specialized health service that greatly affects the health, welfare, and well-being of the patient. It can be rendered only by the true professional who is educated in the biomedical sciences.- - - - - - - - - - ranking = 1.0172808024602keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
3/19. Oral lesions in patients with psoriasis: clinical presentation and management.psoriasis is a chronic inflammatory skin disease that rarely involves the oral cavity. In this report we describe 2 cases, initially diagnosed with cutaneous psoriasis, that present with oral lesions on the attached gingiva. The clinical appearance and differential diagnosis are presented and discussed. Case 1 describes the non-surgical management of intraoral psoriasiform lesions and the use of a free gingival graft to restore an area of gingival recession resulting from an oral lesion. The second case outlines the use of topical corticosteroid therapy as an adjunct to non-surgical periodontal therapy. Although patients with cutaneous psoriasis rarely present with oral involvement, the clinician should be aware that oral lesions may occur. Accurate diagnosis is dependent on a thorough clinical examination, a biopsy of the oral lesions, and a history of cutaneous psoriasis.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/19. Strain persistence of invasive candida albicans in chronic hyperplastic candidosis that underwent malignant change.OBJECTIVES: The aim of this study was to assess persistence and tissue invasion of candida albicans strains isolated from a 65 year-old patient with chronic hyperplastic candidosis (CHC), that subsequently developed into squamous cell carcinoma (SCC). MATERIALS AND methods: C. albicans (n=7) were recovered from the oral cavity of the patient over seven years. Confirmation of CHC and SCC in this patient was achieved by histopathological examination of incisional biopsy tissue. dna fingerprinting was performed on the seven isolates from the CHC patient together with a further eight isolates from patients with normal oral mucosa (n=2), chronic atrophic candidosis (n=1), SCC (n=1) and CHC (n=4). Genotyping involved the use of inter-repeat PCR using the eukaryotic repeat primer 1251. Characterisation of the tissue invasive abilities of the isolates was achieved by infecting a commercially available reconstituted human oral epithelium (RHE; SkinEthic, Nice, france). After 24 h, C. albicans tissue invasion was assessed by histopathological examination. RESULTS: dna fingerprinting demonstrated strain persistence of C. albicans in the CHC patient over a seven year period despite provision of systemic antifungal therapy. The strain of C. albicans isolated from this patient was categorised as a high invader within the RHE compared to other isolates. CONCLUSIONS: Candidal strain persistence was evident in a patient with CHC over seven years. This persistence may be due to incomplete eradication from the oral cavity following antifungal therapy or subsequent recolonisation from other body sites or separate exogenous sources. The demonstration of enhanced in vitro tissue invasion by this particular strain may, in part, explain the progression to carcinoma.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
5/19. Chronic mucocutaneous candidiasis: a case report.Chronic mucocutaneous candidiasis is a immuno deficiency disorder primarily due to T cell dysfunction characterized by persistent candidal infection of mucous membrane, skin, scalp and nails. Chronic mucous membrane candidiasis has an onset in infancy or childhood; the primary affected site is the oral cavity; however, lesions may occur on trunk, hands, feet and scalp. This paper describes a 12-year-old girl with candidial infection of the oral mucosa and extra oral involvement of fingers, nails, toes and intertragus area.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
6/19. DNA identification of the pathogen of candidal aspiration pneumonia induced in the course of oral cancer therapy.Aspiration of oropharyngeal bacteria and fungi is occasionally suspected in patients with pneumonia. A patient with oral carcinoma underwent chemoradioimmunotherapy and, about 4 weeks from the start of the therapy, the patient suffered from severe oral mucositis induced by chemoradiotherapy, and candidal pneumonia was subsequently induced. The candidal pneumonia was insufficiently improved by potent antifungal drugs, taking a lethal course. Randomly amplified polymorphic DNA analysis and DNA sequence examination of strains isolated from the oral cavity 1 week before the onset of pneumonia and autopsied lung revealed the identity of both strains as candida albicans, and the DNA analysis supported aspiration of oral Candida. These results indicate that the pathogen of the pneumonia, C. albicans, was aspirated from the oral cavity and that oral Candida is easily aspirated and becomes the pathogen of pneumonia.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
7/19. oral manifestations during chemotherapy for acute lymphoblastic leukemia: a case report.A 14-year-old, male patient was referred for the treatment of mucositis, idiopathic facial asymmetry, and candidiasis. The patient had been undergoing chemotherapy for 5 years for acute lymphoblastic leukemia. He presented with a swollen face, fever, and generalized symptomatology in the mouth with burning. On physical examination, general signs of poor health, paleness, malnutrition, and jaundice were observed. The extraoral clinical examination showed edema on the right side of the face and cutaneous erythema. On intraoral clinical examination, generalized ulcers with extensive necrosis on the hard palate mucosa were observed, extending to the posterior region. Both free and attached gingivae were ulcerated and edematous with exudation and spontaneous bleeding, mainly in the superior and inferior anterior teeth region. The tongue had no papillae and was coated, due to poor oral hygiene. The patient also presented with carious white lesions and enamel hypoplasia, mouth opening limitation, and foul odor. After exfoliative cytology of the affected areas, the diagnosis was mixed infection by candida albicans and bacteria. Recommended treatment was antibiotics and antifungal administration, periodontal prophylaxis, topical application of fluor 1.23%, and orientation on and control of proper oral hygiene and diet during the remission phase of the disease.- - - - - - - - - - ranking = 0.034561604920411keywords = mouth (Clic here for more details about this article) |
8/19. A trifungal infection of the mandible: case report and literature review.Orofacial fungal infections are occasionally seen in the immunocompromised patient. In this case, a patient with a relapse of an acute lymphoblastic leukemia (ALL) developed a fatal mandibular infection. This may be the first reported case of a trifungal infection with zygomycosis, aspergillosis, and candidiasis in the oral cavity and the fifth mandibular zygomycosis case. epidemiology, diagnosis, treatment and prognosis of zygomycosis infection are reviewed, along with the 4 mandibular zygomycosis cases found in the English literature.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
9/19. Pulmonary nocardiosis associated with primary nocardial infection of the oral cavity.A case of pulmonary nocardiosis associated with primary nocardial infection of the oral cavity in a compromised host is presented. nocardia asteroides, an aerobic, gram-positive, branching, filamentous fungus, was demonstrated in the sputum and in pathologic specimens from gingival sulci stained by Gram's method and the acid-fast method Kinyoun. The organism was identified in cultures made on Sabouraud's glucose agar. Marked clinical improvement was noted when the patient received high dosage of sulfisoxazole diolamine (8 to 12 Gm. per day) for a prolonged period of time (9 to 12 months). Because of an apparent relative increase in the incidence of nocardiosis and a paucity of information on the subject in the dental literature, this article is timely.- - - - - - - - - - ranking = 5keywords = oral cavity, cavity (Clic here for more details about this article) |
10/19. Autoinoculated palmar pustules in neonatal candidiasis.A 2-week-old infant had grouped pustules on the right hand, wrist, and antecubital flexure that appeared after the first week of life. The infant was seen repeatedly to suck the involved areas of the hand and wrist. Clinically typical candidiasis was noted in the oral cavity and the diaper area. Wright's-stained smears of pustular contents, potassium hydroxide preparations of pustular material, and scale from the diaper dermatitis confirmed the presence of pseudohyphae and budding yeasts in all the involved sites. This case demonstrates fairly typical manifestations of neonatal-onset candidiasis, with the unusual feature of unilateral upper extremity pustules that appeared to represent an autoinoculated cutaneous infection.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
