Minimally Invasive Semiconductor Laser Surgery Combined with 5-ALA Photodynamic Therapy for a Chronic Hyperplastic Candidiasis Patient Who Is Ineffective to Antifungal Therapy.

Background: Chronic hyperplastic candidiasis (CHC) is a chronic oral mucosal infection caused by Candida, which has potential for malignant transformation. Diagnosing CHC can be challenging due to its various manifestations. In addition, fungal treatments often prove to be ineffective, highlighting the urgent need for a new safe and efficient treatment approach. Given the potential of CHC to transform into malignancy, it is crucial to emphasize dynamic monitoring and follow-up after treatment. Objective: We attempted to investigate the effect of semiconductor laser pretreatment combined with 5-amino-levulinic acid (5-ALA) photodynamic therapy (PDT) for CHC. Methods: We presented the successful treatment of CHC with mild dysplasia in a 30-year-old man using semiconductor laser and 5-ALA PDT after antifungal therapy proved ineffective. Toluidine blue staining, autofluorescence imaging, and DNA image cytometry were combined to dynamically monitor the progress of the disease. Results: We have obtained positive outcomes with the use of laser combined with PDT treatment. The patients experienced only mild adverse reactions after the treatment, and there was no indication of recurrence or malignant transformation during the subsequent follow-up period, as observed through various auxiliary examinations. Conclusions: This case report suggests that semiconductor laser surgery combined with PDT could be a promising treatment option for patients with CHC who do not respond to antifungal therapy. In addition, the use of combined noninvasive examinations might provide a more accurate assessment of malignant transformation in patients with CHC.

Chronic Oral Lesions.

Chronic oral mucosal lesions can be associated with several mucocutaneous diseases. This article reviews the autoimmune and immune-mediated, reactive, genetic, and infectious diseases that may present with chronic oral and/or cutaneous manifestations and provides a rational approach to diagnosis and management.

Atividade in vitro do extrato etanólico de própolis e do digluconato de clorexidina sobre as espécies de Candida isoladas da mucosa bucal de pacientes internados em Unidade de Terapia Intensiva (UTI) / In vitro activity of ethanolic extract of propolis and chlorhexidine digluconate on Candida species isolated from the oral mucosa of patients hospitalized in the Intensive Care Unit (ICU)

Avaliou-se a atividade dos extratos de própolis e digluconato de clorexidina em Candida sp isoladas da mucosa bucal de pacientes em UTI. Foram determinadas as concentrações fungicidas mínimas (CFM) e comparadas, nas doses sub-inibitórias, à produção de exoenzimas proteinase e fosfolipase e formação de franjas. Em 72 isolados foram avaliadas a atividade antifúngica pela técnica de microdiluição em série, na “base 2”, a produção das exoenzimas proteinase e fosfolipase, e a formação de franjas, antes e após a exposição às própolis e clorexidina. Dos 72 isolados, 53 eram C. albicans, 11 C. tropicalis, quatro C. guilhermondii e quatro sugestivas de C. dubliniensis. CFM 90% do extrato de própolis foi de 5% para C. albicans, 20% C. tropicalis, 0,625% C. guilhermondii e 0,312% sugestivas de C. dubliniensis. CFM 90% da clorexidina foi de 0,0018% para C. albicans, 0,012% C. tropicalis, de 0,0018% C. guilhermondii e de 0,00375% sugestivas de C. dubliniensis. Ocorreu inibição das exoenzimas e franjas, em ambos os produtos. Apesar da inibição da clorexidina ser menor que a da própolis, seu uso diário não causa efeitos colaterais indesejáveis como manchas nos dentes e na língua, perda do paladar e sensação de queimação na mucosa bucal.

The activity of propolis extract and chlorhexidine digluconate on Candida sp isolated from oral mucosa of patients in ICU was evaluated. The minimum fungicidal concentrations (MFC) were determined, and also the production of proteinase and phospholipase exoenzymes and the fringe formation. Seventy-two isolates were used and identified by the API 20C AUX® System. The antifungal activity was evaluated by “at base 2” serial microdilution technique. Also the exoenzymes production (proteinase and phospholipase), the fringes formation, before and after being exposed to propolis and chlorhexidine, were analysed. Of 72 isolates, 53 were C. albicans, 11 C. tropicalis, four C. guilhermondii and four suggestive C. dubliniensis. The MFC 90% of propolis extract was 5% C. albicans, 20% C. tropicalis, 0.625% C. guilhermondii; and 0.312% suggestive of C. dubliniensis. MFC 90% of chlorhexidine was 0.0018% C. albicans, 0.012% C. tropicalis, 0.0018% C. guilhermondii and 0.00375% suggestive of C. dubliniensis. The inhibition of exoenzymes and fringes occurred in the both products. Although the inhibition of chlorhexidine is lower than that showed by propolis, its daily use neither cause undesirable side effects as blemishes on the teeth and tongue, nor the loss of the taste and the burning sensation in the oral mucosa.

The potential management of oral candidiasis using anti-biofilm therapies.

Candida albicans is a minor component of the oral microbiota and an opportunistic pathogen that takes advantage of the immunocompromised host and causes oral mucositis and oral candidiasis. This organism is able to undergo phenotypic modification from a yeast to hyphae growth phase, one of the key arsenals for immune cell evasion, tissue invasion and biofilm formation. The latter property coupled with overgrowth and immune compromising factors such as HIV/AIDS, cancer treatments, organ transplantation, diabetes, corticosteroid use, dentures, and broad-spectrum antibiotic use have modified the fungus from a normal component of the microflora to a foe of an oral cavity and resulting in reduced sensitivity towards commonly utilised antifungal agents. Hence, the need for alternative therapy to curb this plight is of importance. Making use of biomolecules produced by Streptococcus mutans, application of lactoferrin which is a nonspecific host defense factor found in saliva with metal chelating and broader antimicrobial properties, use of probiotics which have the capacity to boost the host immunity through eliciting Immunoglobulin A synthesis, and perturbing the pathogen's environment via competition of space and food, and application of photodynamic therapy can help to manage the burden of oral candidiasis.

Children Undergoing Chemotherapy: Is It Too Late for Dental Rehabilitation?

Children undergoing cancer therapy encounter a diverse spectrum of oral changes that generally are attributed to immunosuppression and bleeding tendencies caused by the therapeutic agents. Therefore, providing oral health instructions and dental rehabilitation before the initiation of cancer therapy is encouraged. In this article, we discuss the general dental management of pediatric patients with cancer actively undergoing cancer therapy, or for whom it is planned. We also describe the dental rehabilitation performed on a child while he was undergoing chemotherapy for neuroblastoma, using an unconventional approach that varied from the standard management protocol used by King Abdulaziz University Hospital. The importance of close collaboration between the medical and dental teams is highlighted.

Persistent and refractory thrush with unknown cause.

Oral thrush is considered as the opportunistic infection, which is caused by fungus Candida albicans. Various kinds of immunodeficiency diseases, such as HIV infection, immunosuppressive therapy, use of broad-spectrum antibiotics, and invasive surgical procedures such as solid organ or bone marrow transplantation, lead to increased susceptibility to fungal infections, but persistent and refractory thrush, with typical clinical signs of oral fungal infection and without any other sign of immunodeficiencies, has not been reported so far. We describe a case of persistent and refractory thrush with Klinefelter syndrome (47, XXY) as the unusual cause.

Atividade antifúngica de produtos naturais indicados por raizeiros para tratamento de candidíase oral / Actividad antifúngica de productos naturales indicados por vendedores de hierbas (raizeiros) para el tratamiento de la candidiasis oral / Antifungal activity of natural products indicated by herb sellers (raizeiros) for the treatment of oral candidiasis

A crescente resistência das leveduras pertencentes ao gênero Candida frente aos antifúngicos sintéticos, atualmente disponíveis no comércio, impulsiona a busca por novos compostos antifúngicos de origem vegetal. Assim, o propósito do presente estudo foi avaliar in vitro a atividade antifúngica dos decoctos de Schinus terebenthifolius Raddi (aroeira) Cinnamomum zeylanicum Breym (canela) e Punica granatum Linn (romã), vendidos por raizeiros em três feiras livres distintas (A, B e C), frente a três espécies de microorganismos do gênero Candida (C. albicans, C. tropicalis e C. krusei). O ensaio para determinação da atividade antifúngica dos produtos naturais foi realizado pelo método da difusão em meio sólido, em triplicata, onde discos de papel de filtro estéreis embebidos em 50 µL dos extratos foram colocados sobre o meio de cultura. Os resultados foram avaliados a partir da mensuração dos diâmetros dos halos de inibição de crescimento fúngico em milímetros (mm), sendo considerada a moda dos valores obtidos. Foi observada atividade antifúngica de S. terebenthifolius Raddi e de C. zeylanicum Breym sobre C. krusei. No entanto, diferenças foram identificadas entre os produtos obtidos nos diferentes locais. O decocto de Punica granatum Linn apresentou atividade antifúngica sobre as três cepas fúngicas utilizadas no estudo. Também foram verificadas diferenças entres os produtos obtidos nas feiras livres, sendo que apenas as amostras de Punica granatum Linn provenientes da feira A foram capazes de inibir o crescimento fúngico de todas as cepas analisadas. Desta forma, conclui-se que todos os produtos avaliados apresentam atividade antifúngica, havendo diferenças relacionadas aos locais de sua obtenção e sensibilidade das cepas ensaiadas(AU)

La resistencia cada vez mayor de levaduras del género candida a los antifúngicos sintéticos disponibles en la actualidad ha llevado a la búsqueda de nuevos compuestos antifúngicos de origen vegetal. El propósito de este estudio fue evaluar la actividad antifúngica in vitro de decocciones de Schinus terebenthifolius Raddi (pimentero brasileño),Cinnamomum zeylanicum Breym (canela) y Punica granatum Linn (granada) sobre tres especies del género Candida (C. albicans, C . tropicalis y C. krusei). Este material vegetal fue vendido por vendedores de hierbas (raizeiros) en tres ferias callejeras distintas (A, B y C). El ensayo para determinar la actividad antifúngica de los productos se realizó por triplicado. Se empleó el método de difusión en medio sólido, en el que discos de papel de filtro estériles fueron empapados en 50 µL de los extractos y colocados en medio de cultivo. Los datos fueron evaluados mediante la medición de los diámetros de los halos de inhibición del crecimiento fúngico, en milímetros, y se consideró la moda de los valores encontrados. Se observó actividad antifúngica de S. terebinthifolius Raddi y C. zeylanicum Breym contra C. krusei, pero fueron identificadas diferencias entre los productos obtenidos en diferentes lugares. La decocción de Punica granatum Linn presentó actividad antifúngica sobre las tres levaduras en estudio. Además, se encontraron diferencias entre los productos adquiridos en las ferias callejeras, pero sólo las muestras de Punica granatum Linn de la feria A fueron capaces de inhibir el crecimiento de hongos de todas las levaduras analizadas. Todos los productos evaluados mostraron actividad antifúngica, pero hubo diferencias en función de la localidad donde los productos fueron obtenidos y de la sensibilidad a las cepas ensayadas(AU)

An increasing resistance of Candida yeasts to the synthetic antifungals currently available has driven the search for new plant-derived antifungal compounds. In this respect, the present study aimed to evaluate the in vitro antifungal activity of decoctions from Schinus terebenthifolius Raddi (Brazilian pepper tree), Cinnamomum zeylanicum Breym (cinnamon) and Punica granatum Linn (pomegranate) against three species of Candida genus (C. albicans, C. tropicalis and C. krusei). Such plant material was sold by herb sellers in three distinct street fairs (A, B and C). The test to determine the products antifungal activity was performed in triplicate by means of the diffusion method on solid medium, in which sterile filter paper discs were soaked in 50 µL of the extracts and then placed on culture medium. Data were assessed by measuring the diameters of halos of fungal growth inhibition, in millimeters (mm), and it was considered the mode of the values found. Antifungal activity of S. terebinthifolius Raddi and C. zeylanicum Breym was observed against C. krusei, but were identified differences among the products obtained in different locations. Punica granatum Linn decoction presented antifungal activity on the three yeasts under study. Also, were found differences among the products acquired in the street fairs, but only the samples of Punica granatum Linn from fair A were able to inhibit fungal growth of all yeasts analyzed. Thus, it is concluded that all the products assessed showed antifungal activity, but differences were found depending on the location where these were obtained and on the sensitivity to the strains assayed(AU)

Dental management of patients irradiated for head and neck cancer.

Patients undergoing radiation therapy as either primary, adjuvant, combination therapy or palliative management of head and neck malignancies are prone to a range of dental complications. Strategies for prevention and management of such complications may be controversial. This article aims to highlight the current understanding and management of the dental needs for patients before, during and after radiation therapy.

Knowledge, attitudes and practices of oral health care workers in Lesotho regarding the management of patients with oral manifestations of HIV/AIDS.

Lesotho has the third highest prevalence of HIV in the world with an estimated 23% of the adult population infected. At least 70% of people living with HIV/AIDS (PLWHA) have presented with oral manifestation of HIV as the first sign of the disease. Oral health workers regularly encounter patients presenting with oral lesions associated with HIV disease and therefore need to have adequate knowledge of these conditions for diagnosis and management. The aim of the present study was to determine the knowledge, attitudes and practices of oral health care workers (OHCW) of Lesotho regarding the management of oral manifestations of HIV/AIDS. A descriptive cross-sectional survey was conducted on all 46 OHCW in 26 public and private care facilities in all ten districts of Lesotho. A self-administered questionnaire was used to gather information. The response rate was 100%. Nearly all (94.7%) agreed that oral lesions are common in people living with HIV and/or AIDS. The majority (91.3%) named oral candidiasis (OC) as the most common lesion found in PLWHA while Kaposi's Sarcoma (KS) (34.7%) and Oral Hairy Leukoplakia (OHL) (32.6%) were mentioned as the least common oral lesions of HIV. Most correctly identified the images of oral candidiasis (97.8%), angular cheilitis (86.9%) and herpes zoster (80.4%). Only 16.7% felt they had comprehensive knowledge of oral HIV lesions, although 84.8% reported having previously received training. Almost three quarters (71%) reported that there was no need to treat HIV positive patients differently from HIV negative patients. OHCW in Lesotho demonstrated high confidence levels in their competence in managing dental patients with oral lesions associated with HIV, however, they lacked an in-depth knowledge in this regard. Amongst this group there is a need for comprehensive training with regards to diagnosis and management of oral lesions of HIV including the training of other cadres of health care workers together with nurses and community health workers.

Oral lesions associated with human immunodeficiency virus disease.

Human immunodeficiency virus (HIV)-associated oral disease among people living with HIV infection includes oral candidiasis, oral hairy leukoplakia, Kaposi sarcoma, oral warts, herpes simplex virus ulcers, major aphthous ulcers or ulcers not otherwise specified, HIV salivary gland disease, and atypical gingival and periodontal diseases. Diagnosis of some oral lesions is based on clinical appearance and behavior, whereas others require biopsy, culture, or imaging for definitive diagnosis. Management strategies including pharmacologic and nonpharmacologic approaches are discussed in this article. Dentists also need to be cognizant of the potential oral side effects of HIV antiretroviral medications.

Effects of probiotic bacteria on Candida presence and IgA anti-Candida in the oral cavity of elderly

Imbalance in the resident microbiota may promote the growth of opportunistic microorganisms, such as yeasts of Candida genus and the development of diseases, especially in aged people. This study evaluated whether the consumption of the probiotic Yakult LB® (Lactobacillus casei and Bifidobacterium breve) was able to influence on the specific immunological response against Candida and on the presence of these yeasts in the oral cavity of 42 healthy aged individuals. Saliva samples were collected before and after the probiotic use for 30 days, 3 times a week. The samples were plated in Dextrose Saboraud Agar with chloramphenicol, the colony-forming units (CFU/mL) were counted and the Candida species were identified. Anti-Candida IgA analysis was conducted using the ELISA technique. ANOVA and Student's t-test were used for normally distributed data and the Wilcoxon test was used for data with non-normal distribution (α=0.05). The results showed a statistically significant reduction (p<0.05) in Candida prevalence (from 92.9% to 85.7%), in CFU/mL counts of Candida and in the number of non-albicans species after consumption of the probiotic. Immunological analysis demonstrated a significant increase (p<0.05) in anti-Candida IgA levels. In conclusion, probiotic bacteria reduced Candida numbers in the oral cavity of the elderly and increased specific secretory immune response against these yeasts, suggesting its possible use in controlling oral candidosis.

Desequilíbrios na microbiota residente podem promover o crescimento de microrganismos oportunistas, como as leveduras do gênero Candida, e o desenvolvimento de doenças, especialmente na população idosa. Este estudo investigou se o consumo do probiótico Yakult LB® (Lactobacillus casei e Bifidobacterium breve) era capaz de influenciar na resposta imune secretória anti-Candida e na presença destes microrganismos na cavidade bucal de 42 idosas saudáveis. Amostras de saliva foram coletadas antes e depois do consumo do probiótico por 30 dias, 3 vezes por semana. As amostras foram semeadas em Agar Saboraud Dextrose com cloranfenicol, as unidades formadoras de colônias (UFC/mL) foram contadas e as espécies de Candida foram identificadas. A análise de IgA anti-Candida foi realizada pela técnica ELISA. Os resultados demonstraram redução na prevalência de Candida (de 92,9% para 85,7%), na contagem de UFC/mL (p≤0,05) e no número de espécies não-albicans, depois do consumo do probiótico. As análises imunológicas mostraram um aumento significativo dos níveis de IgA anti-Candida (p≤0,05). Concluindo, as bactérias probióticas reduziram significantemente a quantidade de Candida na cavidade bucal dos idosos e aumentaram a resposta imune secretória específica para esta levedura, sugerindo a possibilidade de sua utilização no controle da candidose bucal.

Oral complications of cancer and cancer therapy: from cancer treatment to survivorship.

Answer questions and earn CME/CNE Oral complications resulting from cancer and cancer therapies cause acute and late toxicities that may be underreported, underrecognized, and undertreated. Recent advances in cancer treatment have led to changes in the incidence, nature, and severity of oral complications. As the number of survivors increases, it is becoming increasingly recognized that the aggressive management of oral toxicities is needed to ensure optimal long-term oral health and general well-being. Advances in care have had an impact on previously recognized oral complications and are leading to newly recognized adverse effects. Here, the authors briefly review advances in cancer therapy, including recent advances in surgery, oral care, radiation therapy, hematopoietic cell transplantation, and medical oncology; describe how these advances affect oral health; and discuss the frequent and/or severe oral health complications associated with cancer and cancer treatment and their effect upon long-term health. Although some of the acute oral toxicities of cancer therapies may be reduced, they remain essentially unavoidable. The significant impact of long-term complications requires increased awareness and recognition to promote prevention and appropriate intervention. It is therefore important for the primary oncologist to be aware of these complications so that appropriate measures can be implemented in a timely manner. Prevention and management is best provided via multidisciplinary health care teams, which must be integrated and communicate effectively in order to provide the best patient care in a coordinated manner at the appropriate time.

Hospital-based emergency department visits with oral candidiasis in the USA.

OBJECTIVES: The aim of this study was to determine the number of hospital Emergency Department (ED) visits with a diagnosis of oral candidiasis for the year 2007 in the USA and to identify the comorbid conditions associated with it. STUDY DESIGN: The Nationwide Emergency Department Sample (NEDS) for 2007 was employed in this study. Patients who visited the ED with a diagnosis of oral candidiasis were selected, and the estimates were projected to the national levels using the discharge weights. Presence of comorbid conditions in these patients was also determined. RESULTS: A total of 249,092 ED visits had oral candidiasis. Most of the patients belonged to the lower socioeconomic strata. Patients presented with a wide range of comorbid conditions and a large percentage of the patients were subsequently hospitalized after ED visits. CONCLUSIONS: A significant number of patients in the US visited the ED with oral candidiasis in the year 2007.

[Oropharyngeal candidiasis and radiotherapy]. / Candidose oropharyngée et radiothérapie.

The oropharyngeal candidiasis is a common condition in cancer patients treated by irradiation, during and after their treatment. For example, almost 70% of patients treated with chemoradiation for head and neck cancer are colonized, and 40% of symptomatic patients have an oropharyngeal candidiasis. Furthermore, we noticed an increase in non-albicans Candida strains, which are present in almost 50% of samples. Cancer treatments, especially radiation therapy, and comorbidities are risk factors of oropharyngeal candidiasis. Oropharyngeal candidiasis has substantial effects on quality of life, and may limit treatment. Epidemiologic data, physiopathology, clinical diagnosis criteria, consequences and treatment of oropharyngeal candidiasis will be discussed in this article.

Radiotherapy complications and their possible management in the head and neck region.

Oral complications from radiation to the head and neck or chemotherapy for any malignancy can compromise patients' health and quality of life and affect their ability to complete planned cancer treatment. For some patients the complications can be so debilitating that they may tolerate only lower doses of therapy, postpone scheduled treatments, or discontinue treatment entirely. Oral complications can also lead to serious systemic infections. Medically necessary oral care before, during, and after cancer treatment can prevent or reduce the incidence and severity of oral complications, enhancing both patient survival and quality of life. In the present article we present an overview of oral complications, and their possible management, after radiation therapy in the head-and-neck region.
