ABSTRACT

ABSTRACT INTRODUCTION: Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE: To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contamination of the sinus in patients who develop maxillary sinus infection. METHODS: Cross-sectional study in 60 palatal roots of the first maxillary molars near the maxillary sinus, that underwent endodontic treatment for apical periodontitis. After removal of the filling material, dentin shavings were collected and placed in test tubes containing Sabouraud dextrose agar and chloramphenicol. The phenotype was determined by macroscopic and microscopic examination of the colonies. For polymerase chain reaction, the primers ITS-5 and ITS-4 were used. The sequences obtained were compared with those deposited at GenBank using the Basic Local Alignment Search Tool program. RESULTS: Filamentous fungi were isolated from 6 of 60 canals (10%):Aspergillus niger (6.7%), Aspergillus versicolor (1.6%), and Aspergillus fumigatus(1.6%). CONCLUSION: Root canals near the maxillary sinus with endodontic treatment and apical periodontitis may exhibit positive cultures for filamentous fungi. Interested professionals should be alert, because these microorganisms have pathogenic characteristics that can cause disease of odontogenic origin in the maxillary sinus.


RESUMO Introdução: Doenças do seio maxilar têm sido associadas à raízes com tratamento endodôntico próximas ao seio maxilar. Objetivo: Investigar a presença de fungos filamentosos em raízes com tratamento endodôntico e lesão periapical, próximas ao seio maxilar, alertando para uma possível contaminação do seio maxilar por via odontogênica. Método: Estudo transversal em sessenta raízes palatinas de primeiros molares superiores próximas ao seio maxilar, com tratamento endodôntico e lesão periapical. Após remoção do material obturador, raspas de dentina foram coletadas e inseridas em tubos de ensaio contendo Agar Sabouraud Dextrose e Clorafenicol. O fenótipo foi determinado pela análise macroscópica e microscópica das colônias. Para o PCR utilizou-se iniciadores ITS-5 e ITS-4. As sequencias obtidas foram comparadas as disponíveis no GenBank utilizando Basic Local Alignment Search Tool. Resultados: Fungos filamentosos foram isolados de 6 dos 60 canais (10%):Aspergillus niger (6,7%), Aspergillus versicolor (1,6%) e Aspergillus fumigatus(1,6%). Conclusão: Raízes próximas ao seio maxilar com tratamento endodôntico e lesão periapical, podem apresentar cultura positiva para fungos filamentosos. Profissionais afins devem estar alerta, pois este micro-organismo possuem características de patogenicidade podendo causar doenças no seio maxilar de origem odontogênica.

ABSTRACT

Tuberculosis (TB) of the maxillary sinus is rare. We describe the clinical presentation, management and outcome in two human immunodeficiency virus (HIV) seronegative patients with histopathologically confirmed maxillary sinus TB. One of the patients who presented earlier in the course of the disease could be managed with antituberculosis treatment alone, while the other who presented late required surgical intervention as well.

ABSTRACT

Mucormycosis, caused by saprophytic fungi of the order Mucorales of the class Zygomycetes, is a rare opportunistic fungal infection, which has a rapidly progressive and fulminant course with fatal outcome. These fungi are ubiquitous, found in soil, bread molds, decaying fruits and vegetables. The most common form of mucormycosis is rhinocerebral and is usually seen in uncontrolled diabetes mellitus or in immunocompromised patients. This fungus invades the arteries, leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case of palatal perforation by rhino-maxillary mucormycosis in an immunocompromised patient. The aim of this article is to draw attention to the clinical presentation and pathogenesis of mucormycosis and to emphasize the need for high degree of suspicion in its diagnosis and management.

ABSTRACT

Não existem dados definitivos e consistentes sobre a real distribuição dos microorganismos presentes em pacientes com Rinossinusite Crônica (RSC). A variabilidade dos resultados de estudos em RSC deve-se às diferentes técnicas utilizadas como método de coleta, variações nos métodos de cultura, uso prévio de antibiótico, dificuldade de se distinguir agentes colonizadores e patogênicos. FORMA DE ESTUDO: Clínico-prospectivo. OBJETIVO: Estudar a incidência dos microrganismos presentes nos pacientes com RSC na nossa região, através da cultura da secreção do seio maxilar, coletada sob visão endoscópica. MATERIAIS E MÉTODOS: Estudo transversal em 62 pacientes com RSC, submetidos à coleta de secreção de seio maxilar por via endoscópica, com material enviado para cultura para diagnóstico microbiológico. RESULTADOS: Das 62 amostras estudadas, em 33 (53,2 por cento) não houve crescimento de microrganismos; 29 (45,2 por cento) apresentaram isolamento de aeróbios; um caso (1,6 por cento) mostrou crescimento de fungo; não houve o isolamento de microrganismos anaeróbios. Pseudomonas aeruginosa foi isolada com maior frequência - em 8 amostras (27,6 por cento), Staphylococcus aureus e Staphylococcus epidermidis em 4 amostras cada um (13,9 por cento), Streptococcus pneumoniae em 3 amostras (10,4 por cento), outros Gram-negativos em 17 amostras (31 por cento). CONCLUSÃO: Pseudomonas aeruginosa, outras bactérias Gram-negativas e Staphylococcus spp constituíram a microbiota predominante nos seios paranasais de pacientes com RSC.


There isn't definitive and consistent data concerning the distribution of bacterial species in patients with Chronic Sinusitis (CS). The variability of the results from studies in CS may be due to the different techniques used as collection method, variations in culture methods, previous antibiotic use, and difficulty in distinguishing bacterial flora from pathogenic agents. STUDY DESIGN: Clinical prospective. AIM: To identify the incidence of microorganisms in patients with CRS by growing bacteria from the secretion of the maxillary sinus. PATIENTS AND METHODS: Cross-sectional study in 62 patients that had undergone FESS for treatment of chronic sinusitis; cultures from the maxillary sinus were obtained. RESULTS: 62 samples, 33 (53.2 percent) had no growth; 29 (45.2 percent) counts of aerobic bacteria; one case (1.6 percent) of fungus growth; we did not find anaerobic bacteria. Pseudomonas aeruginosa was the one more frequently found - 8 samples (27.6 percent), Staphylococcus aureus and Staphylococcus epidermidis in 4 samples each; Streptococcus pneumoniae in 3 samples (10.4 percent); other Gram negative agents in 17 samples (31 percent). CONCLUSION: In the present study we concluded that Pseudomonas aeruginosa, other Gram negatives bacteria and Staphylococcus spp were the representatives of the bacterial flora found in the paranasal sinuses of patients with CS.

ABSTRACT

The authors describe a rare case of an infection of both the chromomycosis and aspergillosis of the maxillary sinus in an immunocompetent 72-year-old female who presented with progressive visual loss and dull aching pain of the left eye. Sinuscopy of the left maxillary sinus showed swelling of the mucosa with clay-like materials. Biopsy from the left maxillary sinus showed the typically characteristic morphology of chromomycosis and culture from sinus tissue which yielded Aspergillus. The patient responded to a combination therapy of surgical excision and antifungal agent.

ABSTRACT

O objetivo deste estudo foi verificar a microbiologia dos seios maxilar e etmoidal em pacientes com rinossinusite crônica com indicação de cirurgia funcional endoscópica dos seios paranasais. Durante a cirurgia coletamos secreção e/ou fragmento de mucosa dos seios maxilar e/ou etmoidal em 41 pacientes. Identificou-se a presença de microorganismos aeróbios em 21 (51 por cento) dos pacientes, anaeróbios em 16 (39 por cento) e fungos em um (2,4 por cento). Os microorganismos mais isolados foram o Staphylococcus coagulase-negativo em cinco pacientes (12por cento) e Staphylococcus aureus em quatro (9,75 por cento). /The aim of this work is to study the microbiology of the maxillary and/or ethmoid sinuses in patients suffering from chronic rhinosinusitis with indication of functional endoscopic sinus surgery. During surgery, we collected secretion and/or fragment of the maxillary and/or ethmoid sinuses mucosa from 41 patients. We identified aerobic microorganisms in 21 patients (51.2 per cent), anaerobic microorganisms in 16 (39 per cent) and fungus in one (2.4 per cent). In the population studied, the most isolated microorganisms were Staphylococcus coagulase negative, found in five patients (12.18 per cent), and Staphylococcus aureus, found in four patients (9.75 per cent)...

ABSTRACT

Sinusite fúngica é uma entidade que vem recebendo especial atenção nos dias de hoje, entre as diversas modalidades de afecções do trato respiratório, devido ao aumento de sua incidência. Para fins de classificação, essa patologia se divide em duas formas: não invasiva (sinusite fúngica alérgica, "bola fúngica" ou micetoma) e invasiva (sinusite fúngica invasiva fulminante, sinusite fúngica indolente ou lentamente invasiva). Sua apresentação clínica é inespecífica, não existindo sinais e sintomas definitivos de seu diagnóstico. Este necessita da comprovação microbiológica, histopatológica, radiológica e endoscópica associadas às observações clínicas. O presente estudo tem como objetivo um relato desses principais achados numa população de 26 pacientes estudados prospectivamente.
