Canaliculite crônica supurativa - aspectos clínicos e terapêuticos: relato de 3 casos / Chronic suppurative canaliculitis - clinical and therapeutic aspects: report of 3 cases

A canaliculite lacrimal é uma afecção rara, cujo principal agente etiológico é o Actinomyces israelii. Ela deve ser considerada como um diagnóstico diferencial nos casos de conjuntivite crônica recorrente. O objetivo deste estudo é relatar 3 casos de pacientes com canaliculite crônica supurativa e diferentes formas de tratamentos. O primeiro paciente apresentou uma canaliculite superior esquerda e foi tratado com uma canaliculotomia. Entretanto, o mesmo desenvolveu uma canaliculite inferior ipsilateral após 6 meses e foi submetido a um esquema de injeção intracanalicular de cefazolina fortificada com resultado satisfatório. O segundo paciente apresentou uma canaliculite inferior esquerda e foi tratado com uma canaliculotomia. O terceiro paciente teve uma canaliculite inferior esquerda e foi submetido a um esquema de injeção intracanalicular de cefazolina fortificada. Ambos obtiveram completa resolução dos sintomas e sinais. O presente estudo demonstra que a irrigação intracanalicular de cefazolina fortificada pode ser uma forma útil de tratamento de canaliculite crônica supurativa com sintomatologia mais branda. O maior benefício desta abordagem é evitar o traumatismo cirúrgico da canaliculotomia.

Lacrimal canaliculitis is a rare disease caused mainly by Actinomyces israelii. It should be regarded as a differential diagnosis of recurrent chronic conjunctivitis. The purpose of this study was to report 3 cases of chronic suppurative canaliculitis and different treatment options. The first patient presented with an upper left canaliculitis and was treated with a canaliculotomy. Nevertheless, he had an ipsilateral lower canaliculitis after 6 months and underwent intracanalicular injections of fortified cefazolin with complete remission. The second patient presented with a lower left canaliculitis and underwent a canaliculotomy. The third patient had a lower left canaliculitis and underwent intracanalicular injections of fortified cefazolin. Both achieved complete remission. The present article demonstrated that intracanalicular irrigation of fortified cefazolin may be a helpful treatment of chronic suppurative canaliculitis with mild symptoms and signs. The most important benefit of this approach is to avoid injury to the lacrimal canaliculus.

Antimicrobial activity of propolis on oral microorganisms.

Formation of dental caries is caused by the colonization and accumulation of oral microorganisms and extracellular polysaccharides that are synthesized from sucrose by glucosyltransferase of Streptococcus mutans. The production of glucosyltransferase from oral microorganisms was attempted, and it was found that Streptococcus mutans produced highest activity of the enzyme. Ethanolic extracts of propolis (EEP) were examined whether EEP inhibit the enzyme activity and growth of the bacteria or not. All EEP from various regions in Brazil inhibited both glucosyltransferase activity and growth of S. mutans, but one of the propolis from Rio Grande do Sul (RS2) demonstrated the highest inhibition of the enzyme activity and growth of the bacteria. It was also found that propolis (RS2) contained the highest concentrations of pinocembrin and galangin.

Fatores enzimáticos de agressão produzidos por bactérias aeróbicas da cavidade bucal / Production of histolytic enzymes by aerobic oral bacteria

Verificou-se a produção de hialuronidase, condroitin sulfatase, lecitinase e gelatinase em diferentes amostras bacterianas, isoladas da cavidade bucal. Hialuronidase foi produzida por 20 das 30 amostras de S. aureus, 18 das 21 amostras de S. pyogenes e todas as 4 amostras de A. viscosus. Nenhuma amostra produziu condrotin sulfatase e gelatinase; todas as 30 amostras de S. aureus e todas as amostras de A. viscosus produziram lecitinase
