Bola fúngica dos seios paranasais: Relato de dois casos e revisão de literatura / Fungus ball of the paranasal sinuses: Report of two cases and literature review

Introdução: Bola fúngica dos seios paranasais é uma infecção não invasiva que se caracteriza por sua cronicidade, sendo a maioria relacionada com tratamento endodôntico prévio. Acomete principalmente o seio maxilar, embora todos os seios possam ser envolvidos. O principal agente etiológico é o Aspergillus spp. A tomografia computadorizada, devido às apresentações radiológicas características, sugere o diagnóstico que é realizado definitivamente através de análises histopatológicas. O tratamento padrão-ouro é a cirurgia sinusal endoscópica com antrostomia meatal média. Objetivo: Relatar dois casos de bola fúngica dos seios paranasais e ressaltar aspectos importantes desta patologia. Relato dos Casos: Caso 1) Paciente do sexo feminino, 78 anos, apresentou-se com queixas de dor facial há 6 meses e história prévia de tratamento endodôntico. Ao exame físico constatou-se a presença de secreção purulenta em meato médio esquerdo. O Raio X apresentou velamento completo do seio maxilar esquerdo, enquanto a tomografia computadorizada mostrou lesão calcificada neste local. Realizou-se sinusotomia que evoluiu bem. Caso 2) Paciente do sexo feminino, 70 anos, procurou atendimento por história de sinusites de repetição. Ao exame físico não se percebeu nenhuma particularidade. A tomografia computadorizada, assim como a ressonância magnética, detectou espessamento da parede mucosa do seio maxilar esquerdo, além de uma massa calcificada. Realizou-se a mesma sequência de tratamento e a paciente também evoluiu bem. Considerações finais: A infecção fúngica deve ser considerada nos pacientes que se apresentam com sinusite crônica, que não respondem ao uso de antibióticos e que possuem história de manipulação endodôntica...

Introduction: Fungal ball of the sinuses is a not invasive infection that if characterizes for its chronicity, being the majority related with previous endodontic treatment. Affect mainly the breasts to maxillary; even so all the breasts can be involved. The main etiological agent is the Aspergillus spp. The computed tomography, had to characteristic the radiological presentations, suggests the diagnosis that is carried through definitively through histopathological analyses. The treatment standard-gold is the sinus surgery with average meatal antrostomy. Objective: Reporting two cases of fungal ball of the sinuses and to stand out important aspects of this pathology. Story of the Cases: Case 1) Patient of the feminine sex, 78 years old, presented itself with complaints of face pain has 6 months and previous history of endodontic treatment. To the physical examination it was evidenced purulent secretion presence in left average meatus. Ray X presented complete veiling of the breasts to maxillary left, while the computed tomography showed injury calcified in this place. Sinusotomy was become fulfilled that evolved well. Case 2) Patient of the feminine sex, 70 years old, looked attendance for history of sinusitis of repetition. To the physical examination no particularity was not perceived. The computed tomography, as well as the magnetic resonance, detected thickening of the mucous wall of the breasts to maxillary left, beyond a calcified mass. It was become fulfilled same sequence of treatment and the patient also evolved well. Final Considerations: The fungal infection must be considered in the patients who if present with chronic sinusitis, that they do not answer to the antibiotic use and that they possess history of endodontic manipulation...

Severe HDL-c reduction during rosiglitazone therapy in an obese woman with type 2 diabetes.

Treatment with rosiglitazone has been associated with severe paradoxical HDL-c reductions. To our knowledge, there are very few reports of this reaction occurring when patients are treated without the combination of a fibrate. A case of severe HDL-c lowering in a patient treated with rosiglitazone without a fibrate is presented. The patient has been treated at a private practice clinic in southern Brazil. A 64-year-old woman with a 2-year history of type 2 diabetes mellitus was referred to her endocrinologist in June 2008. Rosiglitazone 4 mg q.d. was prescribed. Nine months later, the patient experienced a 90.90% decrease of her HDL-c levels. Rosiglitazone was withdrawn and the HDL-c returned to baseline. This paradoxical HDL-c reduction is a potentially severe adverse event. Patients prescribed rosiglitazone should have their HDL-c levels measured before and during therapy.

O tratamento com rosiglitazona tem sido associado a reduções paradoxais e severas no HDL-c. Há muito poucos relatos dessa reação ocorrendo em pacientes tratados com rosiglitazona sem a combinação com um fibrato. Apresentou-se um caso de diminuição severa no HDL-c em uma paciente tratada com rosiglitazona sem fibrato associado. A paciente foi tratada em uma clínica privada no Sul do Brasil. Uma mulher de 64 anos com história de diabetes melito tipo 2 há 2 anos foi encaminhada ao seu endocrinologista em junho de 2008. Prescreveu-se rosiglitazona 4 mg uma vez ao dia. Nove meses depois, a paciente teve redução de 90,90 por cento em seus níveis de HDL-c. A rosiglitazona foi retirada e o HDL-c retornou aos níveis prévios. Essa redução paradoxal do HDL-c é um evento adverso potencialmente severo. Pacientes aos quais se prescreve rosiglitazona devem ter seus níveis de HDL-c medidos antes e durante o tratamento.
