ABSTRACT

Abstract Objectives To evaluate the colonization dynamics of subgingival microbiota established over six months around newly installed dental implants in periodontally healthy individuals, compared with their corresponding teeth. Methodology Seventeen healthy individuals assigned to receive single dental implants participated in the study. Subgingival biofilm was sampled from all implant sites and contralateral/ antagonist teeth on days 7, 30, 90, and 180 after implant installation. Microbiological analysis was performed using the Checkerboard DNA-DNA hybridization technique for detection of classical oral taxa and non-oral microorganisms. Significant differences were estimated by Mann-Whitney and Friedman tests, while associations between implants/teeth and target species levels were assessed by linear regression analysis (LRA). Significance level was set at 5%. Results Levels of some species were significantly higher in teeth compared to implants, respectively, at day 7 ( V.parvula , 6 × 10 5 vs 3 × 105 ; Milleri streptococci , 2 × 10 6 vs 6 × 10 5 ; Capnocytophaga spp., 2 × 10 6 vs 9 × 10 5 ; E.corrodens , 2 × 10 6 vs 5 × 10 5 ; N. mucosa , 2 × 10 6 vs 5 × 10 5 ; S.noxia , 2 × 10 6 vs 3 × 10 5 ; T.socranskii , 2 × 10 6 vs 5 × 10 5 ; H.alvei , 4 × 10 5 vs 2 × 10 5 ; and Neisseria spp., 6 × 10 5 vs 4 × 10 4 ), day 30 ( V.parvula , 5 × 10 5 vs 10 5 ; Capnocytophaga spp., 1.3 × 10 6 vs 6.8 × 10 4 ; F.periodonticum , 2 × 10 6 vs 10 6 ; S.noxia , 6 × 10 5 vs 2 × 10 5 ; H.alvei , 8 × 10 5 vs 9 × 10 4 ; and Neisseria spp., 2 × 10 5 vs 10 6 ), day 120 ( V.parvula , 8 × 10 5 vs 3 × 10 5 ; S.noxia , 2 × 10 6 vs 0; and T.socranskii , 3 × 10 5 vs 8 × 10 4 ), and day 180 ( S.enterica subsp. enterica serovar Typhi, 8 × 10 6 vs 2 × 10 6 ) (p<0.05). Implants showed significant increases over time in the levels of F.nucleatum , Gemella spp., H.pylori , P.micra , S.aureus , S.liquefaciens , and T.forsythia (p<0.05). LRA found that dental implants were negatively correlated with high levels of S. noxia and V. parvula (β=-0.5 to -0.3; p<0.05). Conclusions Early submucosal microbiota is diverse and only a few species differ between teeth and implants in the same individual. Only 7 days after implant installation, a rich microbiota can be found in the peri-implant site. After six months of evaluation, teeth and implants show similar prevalence and levels of the target species, including known and new periodontopathic species.

ABSTRACT

Las situaciones de crisis en la sala de operaciones son eventos poco frecuentes, con personal trabajando rápido y bajo presión, intentando sobrellevar el incidente con los menores riesgos para el paciente. Se expone un caso clínico en el marco del trabajo de una unidad de anestesia para cirugía de tórax en la cual se presenta una crisis asistencial abordada por un equipo de trabajo capacitado mediante simulación en la aplicación de la herramienta de "Manejo de los Recursos en Crisis (CRM)". Planteamos que la aplicación de esta herramienta por un equipo capacitado en su utilización contribuyó al éxito y buena evolución de un paciente crítico.


Crisis situations on the operation room seldom happen, with staff working fast and under pressure, trying to overcome the incident at the same time as reducing the risks for the patient. Here we expose a clinical case on the frame of work of an anesthesia unit assembled for thorax surgery during which an asistential crisis occurs and is managed by a group of coworkers trained by means of simulation on the appliance of the tool called "Crisis Resource Management (CRM)". We support the idea that the appliance of this tool by a team of professionals trained on its use, contributed to the success and good evolution on a critical patient.

ABSTRACT

Com o aumento do número de indivíduos reabilitados com implantes dentários, novas complicações clínicas estão surgindo, incluindo as doenças peri-implantares. Várias terapias conservadoras e cirúrgicas têm sido propostas para o tratamento da peri-implantite. Estas abordagens cirúrgicas podem ser complementadas com métodos regenerativos, nos quais poderiam ser englobadas as terapias com fibrina rica em plaquetas e leucócitos (L-PRF). Objetivo: O objetivo deste estudo é relatar um caso clínico de peri-implantite tratado com o emprego de L-PRF após 12 meses a partir da intervenção. Relato de caso: O paciente relatado apresentava três implantes instalados há 9 anos, que apresentavam médias de profundidade de sondagem e de nível clínico de inserção de 3,1 e 2,7 mm, respectivamente. O tratamento da peri-implantite consistiu em desbridamento com instrumentos manuais através de acesso cirúrgico e irrigados com clorexidina a 0,12%. Após estes procedimentos, os implantes receberam membrana de fibrina obtidas com a técnica para L-PRF. Após 12 meses, foi constatado redução das bolsas peri-implantares com redução de profundidade de sondagem para 2,3 mm e de nível clínico de inserção para 2 mm. No exame radiográfico, foi possível observar sinais radiográficos indicativos de preenchimento dos defeitos ósseos. Conclusão: O tratamento utilizado para tratar o caso de peri-implantite relatado, mecânico com acesso cirúrgico e uso de L-PRF, apresentou bons resultados clínicos e radiográficos aos 12 meses (AU)


Along with the increasing number of subjects receiving dental implants, new clinical complications are emerging, including peri-implant diseases. Different conservative techniques are being proposed to treat peri-implantitis. Such approaches include regenerative methods, in which leucocyte - and platelet - rich fibrin (L-PRF) is one of them. Aim: The aim of this study is to present a follow up of a clinical case of peri-implantitis treated with the use of L-PRF. Case report: The individual in this report had three dental implants installed 9 years before, presenting mean probing depth and clinical attachment level of 3.1 and 2.7 mm, respectively. The peri-implantitis treatment was performed by debridement of implants with manual instruments in a surgical approach, and irrigation with 0.12% chlorhexidine. After, implants received fibrin membrane obtained using the L-PRF method. At the 12 months follow up, it was observed a reduction in the probing depth and the clinical attachment level to 2.3 mm and 2 mm, respectively. Radiographic examinations showed indications of bone defect filling. Conclusion: The employed treatment to treat periimplantitis, mechanical with surgical approach and use of L-PRF, showed good clinical and radiographic results at 12 months of observation.(AU)

ABSTRACT

Presentamos un caso que se reporta en la literatura médica como embarazo ectópico en cicatriz de cesárea. Esta paciente consultó por sangrado vaginal y hematuria asociados a embarazo de 12 semanas; la ecografía reportó pérdida de la relación placentamiometrio en pared ístmica anterior. El manejo se hizo mediante una histerectomía abdominal. El abordaje actual más aceptado es conservador, sin embargo unas guías de tratamiento universal no han podido ser establecidas

ABSTRACT

Hemos analizado los resultados obtenidos en 180 ciclos consecutivos de 131 pacientes en las que se realizó una transferencia intratubaria de gametos entre los años 1993-1996 en el Instituto de Ginecología y Fertilidad (IFER). La edad promedio de las mismas era de 33,8ñ4,1 años, siendo de 28,7ñ5,4 en las menores de 37 años y de 39,2ñ2,1 en las mayores de 37 años. El promedio de años de esterilidad era de 4,1ñ2,8 años, siendo el tiempo de esterilidad de 3,8ñ2,5 en las menores de 37 años y de 4,6ñ3,2 en las de edad mayor o igual a 37 años. Las causas por las que se realizó el procedimiento fueron: 45 ciclos de endometriosis, 40 de esterilidad sin causa aparente, 30 de factor masculino, 24 de factor tubo peritoneal y 26 de síndrome de ovario poliquístico. El porcentaje de embarazos global fue de 35,7 por ciento por ciclo de captación con un 16,9 por ciento de abortos y un porcentaje de nacidos vivos de 29,7 por ciento, con un 23,7 de embarazos múltiples y un 1,6 de embarazos ectópicos. El índice de implantación fue del 12 por ciento. Los resultados obtenidos más los datos aportados por la bibliografía nos permiten sostener que este procedimiento mantiene su vigencia al momento actual, en todas las indicaciones de infertilidad a excepción del factor masculino severo, siendo la edad de las pacientes un factor importante en el logro de embarazos
