Pansinusitis aguda odontogénica en adolescente: Reporte de caso / Acute odontogenic pansinusitis in adolescent: Case report

RESUMEN: La Pansinusitis aguda odontogénica es un cuadro infeccioso infrecuente que afecta a todos los senos paranasales, en el cual se hace necesario un diagnóstico precoz para obtener una menor morbilidad. Un correcto diagnóstico requiere una evaluación dental exhaustiva, apoyándose con imágenes apropiadas. El presente caso clínico reporta paciente femenino de 17 años, sin enfermedades crónicas de base, diagnosticada con pansinusitis aguda odontogénica a través de examen de tomografía axial computarizada. Fue manejada de forma intrahospitalaria con un equipo multidisciplinario para su recuperación. Tratada con antibioterapia de amplio espectro vía parenteral y manejo del dolor, posterior al alta médica se realizó endodoncia del diente afectado y rehabilitación con prótesis fija unitaria.

ABSTRACT: Acute Odontogenic Pansinusitis is an infrequent infectious disease that affects all the paranasal sinuses. It requires an early diagnosis to obtain a lower morbidity. A correct diagnosis requires thorough dental evaluation, supported by appropriate images. The present clinical case reports a 17-year-old female patient, without chronic underlying diseases, with anacute Odontogenic Pansinusitis diagnosed through a computerized axial tomography scan. She was treated by a multidisciplinary team for recovery, through parenteral wide spectrum antibiotic therapy and pain management. After medical discharge, root canal of the affected tooth and rehabilitation with fixed unitary prosthesis were performed.

Campylobacter species in chilean patients with chronic periodontitis / Espécies de Campylobacter em pacientes chilenos com periodontite crônica

The purpose of this study is to identify the presence of Campylobacter species (C. rectus, C. concisus, C. gracilis and C. ureolyticus) in Chilean patients with chronic periodontitis, and to establish the relationship of these microorganisms with the periodontal conditions of smoker and non-smoker patients. Subgingival plaque samples were collected from four periodontal-affected tissue sites of 15 smoker and 15 non-moker patients with chronic periodontitis. A sample per quadrant was obtained, with a probing depth of 6 mm and an insertion loss of >3 mm in each patient. Polymerase chain reaction (PCR) was performed with the specific 16S rDNA primers for the molecular detection of C. rectus and C. gracilis, specific cpn60 primers for C. concisus and hsp60 primers gene for C. ureolyticus. Campylobacter species showed an overall prevalence of 93.3% in periodontal patients, while C. rectus was the most frequent one (80%), followed by C. concisus (66.7%), C. gracilis (33.3%), and C. ureolyticus (10%). Only C. gracilis showed a statistically significant (p = 0.002) association with chronic periodontitis among samples from smoker and nonsmoker patients. A high prevalence of the Campylobacter genus in the analyzed populations (93.3%) was found, being C. rectus the most frequent (80%) species. Besides, C. gracilis showed a statistically significant association between smoker state and chronic periodontitis.

O objetivo deste estudo é identificar a presença de espécies de Campylobacter (C. rectus, C. concisus, C. gracilis e C. ureolyticus) em pacientes chilenos com periodontite crônica, e estabelecer a relação desses microrganismos com as condições periodontais de pacientes fumantes e não fumantes. Amostras de placa subgengival foram coletadas de quatro locais de tecido periodontal afetado de 15 pacientes fumantes e 15 não fumantes com periodontite crônica. Obteve-se uma amostra por quadrante, com profundidade de sondagem 6 mm e perda de inserção > 3 mm em cada paciente. A reação em cadeia da polimerase (PCR) foi realizada com os primers específicos 16S rDNA para a detecção molecular de C. rectus e C. gracilis, primers específicos de cpn60 para C. concisus e gene primers de hsp60 para C. ureolyticus. As espécies de Campylobacter apresentaram uma prevalência geral de 93,3% nos pacientes periodontais, enquanto C. rectus foi o mais frequente (80%), seguido por C. concisus (66,7%), C. gracilis (33,3%) e C. ureolyticus (10%). Apenas C. gracilis apresentou associação estatisticamente significante (p = 0,002) com a periodontite crônica entre as amostras de pacientes fumantes e não fumantes. Observou-se alta prevalência do gênero Campylobacter nas populações analisadas (93,3%), sendo C. reto as espécies mais frequentes (80%). Além disso, C. gracilis mostrou associação estatisticamente significante entre estado de fumante e periodontite crônica.
