1/168. 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. ( info)

2/168. Successful treatment of fluconazole-resistant oropharyngeal candidiasis by a combination of fluconazole and terbinafine.

    Increasing incidence of resistance to conventional antifungal therapy has demanded that novel therapies be introduced. Recent in vitro studies have shown that combinations involving azoles and allylamines may be effective in inhibiting fluconazole-resistant fungi. In this report, we describe the case of a 39-year-old woman who presented with white patches on her buccal mucosa, tongue, and palate with a bright erythematous erosive base. A fungal culture revealed candida albicans. The patient failed to respond to the initially prescribed fluconazole therapy. Failure of therapy can be attributed to a developed resistance to fluconazole from the patient's intermittent use of this antifungal agent at varying dosages for the preceding 2 years due to a diagnosis of onychomycosis. in vitro testing of the culture from the patient showed elevated MICs of fluconazole, itraconzole, and terbinafine (MICs were 32, 0.5, and 64 microg/ml, respectively). Our goal was to combine therapies of fluconazole and terbinafine in an attempt to clear the fungal infection. Impressively, this combination resulted in the clearing of the clinical symptoms and the patient has successfully been asymptomatic for more than 12 months posttreatment. ( info)

3/168. Recovery of Candida dubliniensis from non-human immunodeficiency virus-infected patients in israel.

    Candida dubliniensis is a recently discovered yeast species principally associated with carriage and disease in the oral cavities of human immunodeficiency virus (HIV)-infected individuals. To date the majority of isolates of this species have been identified in europe and north america. In this study, five Candida isolates recovered from separate HIV-negative hospitalized patients in Jerusalem, israel, were presumptively identified as C. dubliniensis on the basis of their dark green coloration when grown on CHROMagar Candida medium. Their identification was confirmed by a variety of techniques, including carbohydrate assimilation profiles, absence of growth at 45 degrees C, positive reaction with C. dubliniensis-specific antibodies as determined by indirect immunofluorescence analysis, and positive amplification with C. dubliniensis-specific PCR primers. All five strains were shown to be susceptible to a range of antifungal agents, including fluconazole. One of the five isolates was recovered from urine specimens, while the remaining four were recovered from upper respiratory tract and oral samples. While none of the patients was HIV positive, all were receiving broad-spectrum antibacterials at the time isolates of C. dubliniensis were obtained from clinical specimens. This study describes the first isolates of C. dubliniensis from the middle east and confirms that this yeast can be associated with carriage and infection in the absence of HIV infection. ( info)

4/168. Spontaneous gingival bleeding in an otherwise asymptomatic patient.

    This case is presented to challenge the reader to formulate a differential diagnosis for a patient who visits the dentist with spontaneous, continuous gingival bleeding. When this situation occurs, it is serious and requires immediate attention and a specific treatment plan to arrive at the underlying diagnosis and control the bleeding. The signs and symptoms of a patient with gingival bleeding are presented for diagnosis; the history and management are detailed, and may be useful in diagnosing and treating similar patients.

5/168. 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. ( info)

6/168. Topical azathioprine in the combined treatment of chronic oral graft-versus-host disease.

    This paper presents the first report of the use of topical azathioprine in the management of persistent symptomatic chronic oral graft-versus-host disease (GVHD). Topical azathioprine suspension was used as an oral rinse and was swallowed, maintaining the previously prescribed systemic dose of azathioprine, and resulted in improvement in a case of oral GVHD that was resistant to other approaches to management. Topical azathioprine may provide additional therapy in the management of immune-mediated oral mucosal disease. Clinical trials appear warranted based upon the results of topical azathioprine use as presented in this case report. ( info)

7/168. Orbital Kaposi's sarcoma in acquired immunodeficiency syndrome.

    A 28-year-old white male with AIDS-C3 staging, presented with an extensive hemorrhagic dark mass localized in the left orbit. No other ophthalmic findings were disclosed. ultrasonography and computed axial tomographic scans showed orbital involvement. Orbital Kaposi's sarcoma is a rare finding and only a few cases have been reported. Systemic examination revealed other lesions suggestive of disseminated mucocutaneous Kaposi's sarcoma, oral candidiasis, membranous esophagitis and granulomatous hepatitis. Eyelid incisional biopsy disclosed Kaposi's sarcoma. Despite intensive chemotherapy progression was aggressive with a fatal outcome. ( info)

8/168. diabetes insipidus in a patient with a highly malignant B-cell lymphoma and stomatitis.

    A 37-year-old male patient with a diffuse pleomorphic B-cell-lymphoma, which has been diagnosed two month earlier with the primary site at the pterygopalatine fossa on both sides with infiltration of the clivus and cavernous sinus was referred to our hospital for continuation of the third course of CHOP chemotherapy. At admission he reported about a recent history of painful swallowing and intermittent substernal chest pain. Alleviation of the pain on swallowing and the chest pain was apparently only possible by drinking 10 to 15 l of cold coca cola throughout the day and night, a regimen that resulted in polyuria. physical examination revealed extensive thrush stomatitis and soor esophagitis. Despite successful treatment with fluconazole, polydipsia continued unabated. The classic osmotic test of dehydration and exogenous vasopressin revealed hypothalamic diabetes insipidus (DI). Basal hormones and stimulated endocrine function tests of the adenohypophysis were found to be normal. MRI-scan revealed lymphoma infiltration of the neurohypophysis. After the third course of CHOP chemotherapy the patient surprisingly recovered completely from his excessive thirst. The present report shows that clinical disorders such as thrush stomatitis can mask diabetes insipidus caused by an early relapsing lymphoma. ( info)

9/168. Identification of Candida dubliniensis in a study of HIV-seropositive pediatric dental patients.

    PURPOSE: The combination of an immature immune system and suppressed cellular immunity in children with hiv infections provides optimal conditions for rapid disease progression. As a result, pediatric AIDS has become a major epidemiological challenge. Oral fungal colonization remains one of the most common opportunistic infections observed in both adult and pediatric HIV infected patients. Although candida albicans is the most frequently isolated opportunistic fungal species, a recently characterized Candida species, C. dubliniensis, has gained considerable attention due to its almost exclusive association with HIV-seropositive individuals. The purpose of this study was to prospectively screen for the presence of C. dubliniensis among pediatric HIV patients. methods: Oral samples taken from twenty-seven children were cultured for the presence of yeast. All positive yeast isolates obtained were screened for the presence of C. dubliniensis by use of tests for germ tube and chlamydospore production, detection of inability to grow at 45 degrees C, by colony color on CHROMagar Candida medium, coaggregation with fusobacterium nucleatum ATCC 49256 and by the results of sugar assimilation testing with the API 20C AUX yeast identification system. RESULTS: Among the 27 patients tested, 3 patients were found to harbor C. dubliniensis, one of which also grew C. glabrata; 12 patients were colonized with C. albicans, while the remaining 12 patients were negative for yeast. Identification of the three C. dubliniensis isolates was genetically confirmed by electrophoretic karyotyping. All three C. dubliniensis isolates were found to be susceptible to fluconazole (MIC < or = 0.25 ug/ml). CONCLUSIONS: These results confirm the presence of this novel species in a dental pediatric HIV seropositive population and support the need for further investigation into the prevalence and pathogenesis of C. dubliniensis.

10/168. Therapeutic experience with fluconazole in the treatment of fungal infections in diabetic patients.

    diabetes mellitus is associated with a higher incidence of certain infections, including fungal infections like rhinocerebral zygomycosis (RCZ) and cutaneous candidosis. As the pathophysiology of increased susceptibility to infection of diabetic patients is very complex, a general therapeutic approach is not existing yet. Appropriate diabetes control remains as the best preventive measure. Nevertheless, effective drug therapy is very often required. fluconazole has proven efficacy in prophylaxis, treatment and suppressive therapy of both systemic and superficial fungal infections, especially in candidosis and cryptococcosis. Therefore it is used routinely against fungal infections in diabetes (FID). Clinical efficacy of fluconazole against cutaneous candidosis, oropharyngeal candidosis (OPC) and vulvovaginal candidosis (VVC) has been confirmed in more than 100 studies, involving more than 10,000 patients (pts). The overall success rate is 90%, with a mean dosage of 100-200 mg/d. In severe cases, e.g. in OPC in late-stage AIDS pts or in recurrent VVC, higher dosages of up to 800 mg/d may be required. In the treatment of RCZ, therapeutic experience with fluconazole is limited. Four diabetic pts have been treated with dosages of 200-300 mg/d and all of them recovered. Nevertheless, treatment of RCZ should include surgical debridement combined with aggressive antifungal therapy. In conclusion, proven efficacy and the excellent safety profile justify the routine use of fluconazole in the treatment of FID. ( info)
