'AIDS' (Acquired Immunity Deficiency Syndrome) is a term used to describe the various clinical syndromes, specific opportunistic infections or malignancies that can occur with HIV infection. Oral manifestations of these diseases are common in people with Human Immunodeficiency Virus (HIV) infection and may be due to a decline in immune function. Hence patients with AIDS are subjected to recurrent, life threatening opportunistic infection. This is a case report of a 70yr old female who presented with infection of the right buccal, masticator and submandibular spaces. A routine blood report revealed seropositivity for HIV infection. She was treated with antibiotics and underwent an incision and drainage following hospitalization.

OBJETIVO: Fibrose submucosa oral (FSO) é uma condição pré-maligna de alto risco que predominantemente afeta jovens da Índia devido ao hábito de mascar 'gutkha'. Candida pode ter um papel importante na etiopatogenia de lesões pré-malignas e malignas. O objetivo deste estudo foi comparar a incidência, intensidade e Candida spp encontradas em pacientes com FSO e em indivíduos saudáveis. METODOLOGIA: Este estudo incluiu 20 pacientes com FSO e 20 controles saudáveis. Obteve-se de cada sujeito uma história detalhada e exame clínico. As amostras foram coletadas com uma técnica de enxágue bucal e cultivadas em meio Agar Sabouraud. As espécies isoladas foram contadas e identificadas com base em coloração Gram, teste de tubo de ensaio e teste de assimilação de açúcar. RESULTADOS: No total, 40% dos pacientes com FSO e 15% dos controles saudáveis apresentaram resultado positivo de cultura para Candida. C. albicans foi a espécie predominante isolada, mas C. krusei e C. tropicalis também foram identificados. O sexo, hábito de mascar 'gutkha' e estadiamento clínico não influenciaram a presença de fungos nos pacientes com FSO. CONCLUSÃO: A incidência e intensidade de Candida (primariamente C. albicans) foi maior nos pacientes com FSO que nos sujeitos controle, mas estes achados estavam dentro dos limites normais (3-47%). Portanto, Candida pode não ser um fator etiológico na transformação maligna. Entretanto, ainda há controvérsias se o hábito de mascar 'betel' em casos de FSO teria um efeito inibidor ou promoveria a aderência e invasão de Candida.

PURPOSE: Oral submucous fibrosis (OSMF) is a high-risk precancerous condition that predominantly affects Indian youngsters due to the habit of gutkha chewing. Candida may play a role in the etiopathogenesis of premalignant and malignant lesions. The aim of this study is to compare the incidence, intensity, and species of Candida found in OSMF patients and healthy individuals. METHODS: This study included 20 OSMF patients and 20 healthy controls. A detailed history of each patient was recorded along with a clinical examination. Samples were collected with the oral rinse technique and cultured on Sabouraud's agar medium. The isolated yeast species were counted and identified based on Gram staining, a germ tube test, chlamydospore formation and a sugar assimilation test. RESULTA: In total, 40% of OSMF patients and 15% of healthy controls yielded Candida organisms on culture. C. albicans was the predominant species isolated, but C. krusei and C. tropicalis were also identified. Gender, gutkha habit and clinical staging had no influence on the candidal carriage in OSMF patients. CONCLUSION: The incidence and intensity of Candida (primarily C. albicans) was greater in OSMF patients than in healthy controls, but these findings were within the normal limit (3-47%). Therefore, Candida may not be an etiologic factor in malignant transformation. However, controversy still exists over whether the chewing of betel quid in cases of OSMF has an inhibitory effect or promotes the adherence and invasion of Candida.
