Academic literature on the topic 'Chronic atrophic candidiasis'

Candida species inhabit the mucosal surfaces of healthy individuals. Major forms of oral candidiasis are pseudomembranous and atrophic form, but chronic hyperplastic candidiasis (CHC) is rarely seen. We encountered a case of whitish plaque with nodule and ulceration. When an intraoral nodule is observed, the possibility of CHC should be taken into consideration. Biopsy of the lesion failed to show any signs of malignancy, and patient responded well to oral fluconazole therapy only. CBMJ 2014 January: Vol. 03 No. 01 P: 53-55

SUMMARYNon-diabetic individuals who are non-secretors of blood group antigens are prone to superficial infections by Candida albicans. In this study, 216 patients with diabetes mellitus who were denture wearers were examined for the presence or absence of denture stomatitis. There was an overall trend for non-secretors to be prone to denture stomatitis compared with secretors. Stepwise linear discriminant analysis was used to dissect the contribution of secretor status and other variables to the development of the disease. Secretor status was found to be a contributory factor among patients with non-insulin dependent diabetes but not among those with insulin-dependent diabetes. The possible reasons for this are discussed.

Objective.To determine the prevalence of oral candidiasis and multiple oralCandidainfections in patients with primary Sjögren’s syndrome (SS), and the clinical and drug susceptibility profile.Methods.Thirty patients with primary SS were enrolled in our study. The diagnosis of oral candidiasis was based on the clinical manifestation, and confirmed by a concentrated rinse culture.Candidaspp. assessment was accomplished using standard methods: Sabouraud dextrose agar with 50 mg/l chloramphenicol and CHROMagar were used for the rapid screening of clinical species, followed by the API 20C system for further species identification.In vitroantifungal drug susceptibility ofCandidaisolates was determined by the minimal inhibitory concentrations.Results.In our study, 87% (26/30) of subjects had oral candidiasis, in which 42% (11/26) had multipleCandidaspp. infection. AlthoughC. albicansremains the predominant isolate, other rare species such asC. tropicalis,C. glabrata,C. parapsilosis, andC. kruseiwere present, alone or in combination. Chronic atrophic candidiasis is the most common clinical type of oral candidiasis in patients with SS. The susceptibilities of the 44Candidaisolates to 7 antifungal agents varied dramatically. The resistance to azoles was remarkable, and the phenomenon of cross-resistance between itraconazole and fluconazole was observed.Conclusion.Patients with primary SS carry a high risk of oral candidiasis and a high frequency of multipleCandidainfections. The azole resistance patterns ofCandidaspp. support the necessity for drug susceptibility testing as a routine procedure for patients with oralCandidainfections.

Abstract The treatment of choice for chronic atrophic candidiasis (CAC), also known as denture stomatitis, is topical antifungal therapy. This study aimed to isolate, identify, and assess the antifungal susceptibility of Candida species from mucosal sites in denture wearers with a diagnosis of CAC and determine the prevalence of associated variables. The sample consisted of 44 patients wearing complete or partial dentures who had a clinical diagnosis of CAC. Using sterile cotton swabs, specimens were collected from the oral mucosa of all patients and grown at 30ºC for 48 h in CHROMagar Candida, as a means of isolating and screening the species. The complementary identification of the species was performed using the VITEK 2 automated system (BioMérieux), as well as the determination of their susceptibility to antifungal agents. Data were analyzed using the chi-square test. STATA 13.1 was used for statistical analysis (α = 5%). Of 44 patients with CAC, 33 (75%) had lesions classified as Newton type II. Yeasts were isolated in 38 cases. The most prevalent species was Candida albicans. None of the isolates were resistant to the antifungals tested. Our findings suggest that current indications for antifungal agents are appropriate. Also, antifungal susceptibility testing and proper fungal identification can help dentists to determine the optimal course of treatment for CAC.

Oral lichen planus is a chronic mucocutaneous disease that is relatively common. Although many patients are asymptomatic and require no therapy, those who exhibit atrophic and erosive lesions are often a challenge to treat. All therapies are palliative, and none is effective universally. Currently employed treatment modalities include corticosteroids administered topically, intralesionally, or systemically. Alternative therapies include topical and systemic retinoids, griseofulvin, Cyclosporine, and surgery. Other medical treatments and experimental modalities, including mouth PUVA, have been reported to be effective. Controversy concerning the efficacy of all these treatments suggests that oral lichen planus is a heterogeneous disorder. Eliminating lichenoid drug eruptions, candidiasis, trauma, contact mucositis, and emotional stress may play a role in the management of these patients. This article is a review of the many treatments and measures that have been employed in the management of patients with oral lichen planus.

The efficacy of 2 oral hygiene products, an experimental toothpaste specific for complete denture cleansing and a regular standard toothpaste, was compared in terms of denture biofilm removal and cure of palatal lesions in patients with atrophic chronic candidiasis. The degree of correlation between presence of biofilm and mucosa erythema was also evaluated. Twenty-four complete denture wearers (45-80 years old) were divided into 2 groups: experimental paste and standard toothpaste (Sorriso-Kolynos, Brazil). Both groups received soft toothbrushes. The internal surfaces of upper dentures were stained using 1% sodium fluorescein and photographed at a 45º angle at 0, 15, 30 and 60 days. The slides were scanned and the areas of interest (denture total area and biofilm area) were measured (Image Tool software). The degree of erythema was evaluated on slides according to the Prosthesis Tissue Index. There was a significant reduction (1%) in the degree of biofilm (ANOVA/Tukey) between the two initial visits (0 and 15 days) and the two final visits (30 and 60 days), and in the average erythema scores (Kruskal-Wallis) between 0 and 60 days, in both groups. The Mann-Whitney test showed a significant difference (1%) between pastes in terms of biofilm degree, but no difference was found for the erythema score. Correlation values between biofilm and erythema degree were 0.3801 (experimental paste) and (0.3678 (standard toothpaste). We may therefore conclude that the experimental product was efficient for the removal of denture plaque biofilm.

Pendahuluan: Stunting adalah keadaan kekurangan gizi kronis yang dipresentasikan secara antropometri berdasarkan nilai Z-score tinggi badan kurang dari -2 standar deviasi (SD) WHO Child Growth Standards pada kelompok umur dan jenis kelamin yang sama. Salah satu faktor utama penyebab stunting adalah defisiensi mikronutrien kronis pada 1000 hari pertama kehidupan secara spesifik pada vitamin B2, vitamin B6, zinc, dan zat besi Di sisi lain, defisiensi tersebut pun dapat menyebabkan berbagai lesi pada rongga mulut. Anak stunting memiliki risiko lebih tinggi pada lesi, penyakit bahkan kematian terutama pada anak stunting kategori sangat pendek. Tujuan penelitian untuk mengetahui profil lesi jaringan lunak rongga mulut pada anak stunting kategori pendek dan sangat pendek. Metode: Jenis penelitian observasional deskriptif dengan pendekatan cross sectional. Teknik pengambilan sampel dengan purposive sampling. Penelitian ini menggunakan data sekunder berupa data rekap bulanan status gizi berdasarkan Z-score oleh Puskesmas Jelbuk dan data primer berupa hasil pemeriksaan rongga mulut pada anak stunting. Hasil: Lesi jaringan lunak rongga mulut pada anak stunting kategori pendek adalah; Glositis (41,9%), Angular cheilitis (16,1%), Ulser (9,6%), Recurrent Apthous Stomatitis (6,4%), Oral Candidiasis (3,3%). Anak stunting kategori sangat pendek: Glositis (53,5%), Angular cheilitis (17,8%), Ulser (3,5%), Recurrent Apthous Stomatitis (7,1%), Oral Candidiasis (3,5%). Simpulan: Lesi jaringan lunak rongga mulut dengan prevalensi terbesar pada kedua kelompok kategori stunting adalah Athropic glossitis. Hal ini perlu mendapat perhatian khusus oleh praktisi kesehatan maupun pemerintah setempat karena kesehatan rongga mulut secara utuh akan memengaruhi asupan nutrisi bagi anak dan sebaliknya.Kata kunci: stunting; jaringan lunak rongga mulut; anak; lesiABSTRACTIntroduction: Stunting is a condition of chronic malnutrition presented anthropometrically based on the Z-score of height less than -2 standard deviations (SD) of the WHO Child Growth Standards in the same age and sex group. One of the main factors of stunting is chronic micronutrient deficiency in the first 1000 days of life, specifically of vitamin B2, vitamin B6, zinc, and iron. On the other hand, these deficiencies can also cause various lesions in the oral cavity. Stunting children have a higher lesion risk, disease, and even death, especially in severely stunted children. This study was aimed to examine the profile of oral soft tissue lesions in stunted and severely stunted children. Methods: The type of research used was descriptive observational research with a cross-sectional approach. The sampling technique used was purposive sampling. This study uses secondary data in the form of monthly recap data on the nutritional status based on Z-score by Jelbuk Health Center and primary data in oral cavity examination results in stunted children. Results: Oral soft tissue lesions in stunted children were glossitis (41.9%), angular cheilitis (16.1%), ulcer (9.6%), recurrent aphthous stomatitis (6.4%), and oral candidiasis (3.3%). Severely stunted children: Glossitis (53.5%), angular cheilitis (17.8%), ulcer (3.5%), recurrent aphthous stomatitis (7.1%), oral candidiasis (3.5%). Conclusions: The oral soft tissue lesion with the highest prevalence in both groups of stunting children was atrophic glossitis. This condition needs special attention from health practitioners and local governments because oral health will affect nutritional intake for children and vice versa.Keywords: stunting, oral soft tissue; children; lesion

A estomatite protética (EP), também designada de candidíase atrófica crônica, é a infecção fúngica bucal mais comum em indivíduos portadores de prótese total. Possui etiologia multifatorial, no entanto a presença de Candida spp. no biofilme da prótese é tida como o fator mais importante para o estabelecimento da EP. Este trabalho teve como objetivo avaliar o tratamento da EP por meio do uso da terapia fotodinâmica antimicrobiana (PDT), mediada pelo azul de metileno. Foram realizados estudos pré-clínicos e clínicos. Protótipos simuladores de prótese total foram confeccionados com polímero de metilmetacrilato, para servir de base para o crescimento do biofilme das seguintes espécies do gênero Candida: C. albicans, C. glabrata, C. dubliniensis, C. krusei, C. tropicalis, C. parapsilosis e C. guilliermondii. Como fotossensibilizador foi utilizada a solução de azul de metileno em uma concentração de 450μg/mL. Os protótipos com os biofilmes foram irradiados com um laser de comprimento de onda de 660 nm, potência de 100 mW, por um tempo de 80 segundos. Para o estudo clínico, os indivíduos foram divididos em dois grupos. O primeiro grupo recebeu tratamento convencional, à base do antifúngico Miconazol. O segundo grupo recebeu como tratamento a PDT. Os resultados pré-clínicos mostraram que todas as espécies do gênero Candida foram susceptíveis à PDT, ocorrendo uma redução de colônias que variou de 2,48 a 3,93 log10. Os resultados clínicos foram avaliados tanto quanto à redução de colônias de Candida spp. na mucosa e na prótese, como quanto à melhora do aspecto clínico da mucosa afetada. Tanto a terapia convencional quanto a PDT foram eficientes em tratar a EP. Não houve diferença estatística significante entre os tratamentos instituídos para nenhum dos fatores avaliados. Assim, concluiu-se que a PDT é efetiva no tratamento da estomatite protética.
Denture stomatitis (DS), also called chronic atrophic candidiasis, is the most common oral fungal infection in denture wearers. It has a multifactorial etiology, but the presence of Candida spp. biofilm on the denture is considered the most important factor for the establishment of the DS. This study aimed to evaluate the treatment of DS through the use of photodynamic antimicrobial therapy (PAT), mediated by methylene blue. For this purpose, preclinical studies and clinical trials were performed. Simulators prototypes dentures were made of methyl methacrylate polymer to serve as a basis for biofilm growth of the following species of Candida: C. albicans, C. glabrata, C. dubliniensis, C. krusei, C. tropicalis, C. parapsilosis and C. guilliermondii. Methylene blue solution at a concentration of 450μg/mL was used as a photosensitizer. The prototypes and biofilms were irradiated with a laser of wavelength of 660 nm, potency of 100 mW, for 80 seconds. For the clinical study, subjects were divided into two groups. The first group received conventional treatment based on the use of antifungal Miconazole. The second group received the treatment by PAT. The preclinical results showed that all species of the genus Candida were susceptible to PAT, with a reduction in colonies that ranged from 2.48 to 3.93 log10. Clinical outcomes were evaluated for the reduction of colonies of Candida spp. located in the mucosa and in the prosthesis and relative to the improvement of the clinical aspect of the affected mucosa. Both the conventional therapy and PAT were effective in treating DS. There was no significant statistical difference between PAT and conventional treatment for any of the factors evaluated. Thus, it was concluded that PAT is effective in the treatment of denture stomatitis.
