Ibero-Panamerican Federation of Periodontology Delphi study on the trends of periodontology and periodontics by the year 2030. A Latin American consensus.

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

está disponible en el texto completo

Introduction: Sleep-disordered breathing (SDB) are highly prevalent in patients with heart failure (HF). The presence of obstructive sleep apnea syndrome (OSA) determines a worse prognosis in these patients. There are questionnaires aimed at evaluating the probability of OSA, although none have been validated in patients with HF. The primary objective of this study was to establish the prevalence of SDB in a cohort of patients with HF and reduced ejection fraction (HFrEF) from the Multidisciplinary HF Unit (UMIC). As a secondary objective, to evaluate the usefulness of the Stop-Bang, Berlin, and 2ABN3M questionnaires for TRS screening in these patients. Methodology: Cross-sectional, observational study, including the active cohort of the UMIC, over 18 years with HFrEF, clinically stable and informed consent. Patients with cognitive, neurological or hearing impairment with limitations when conducting the interview were excluded. Patients with other limiting or uncontrolled sleep disorders, continuous home oxygen therapy requirements, did not enter the study. Berlin, Stop-Bang, and 2ABN3M questionnaires were administered, classifying the population into high-risk, intermediate-risk, and low-risk groups of presenting SDB. All patients underwent outpatient respiratory polygraphy (RP). Descriptive statistics were used to characterize demographic variables, measures of central tendency and dispersion. SPSS statistical software was used. Results: 387 patients were included, 248 men (64.1%), mean age was 63.5 ± 0.6 years. The etiology of HF was ischemic in 41.6% of patients. The body mass index was 29.3 ± 0.3 kg/m2. LVEF was 34.2 ± 0.5, pro-BNP 1233.8 ± 137.6 pg/ml. The results of the questionnaires showed that 52.1% (198) presented a high risk of SDB according to the Berlin questionnaire. With Stop-Bang, 35.9% (139) were high risk, 42.1% (163) intermediate risk, and the remaining 22% (85) low risk. With the 2ABN3M score, 62% (240) were high risk. A total of 156 respiratory polygraphs (40.3% of the population) were performed. The cut-off point to define the presence of sleep apnea was considered to be an AHI >15. 58.3% (91) of the patients presented TRS. Of these, 95% presented obstructive apnea and 5% central apnea with periodic Cheyne-Stokes breathing. A high percentage (26%) presented AHI greater than 30. The sensitivity of the Berlin and Stop-Bang questionnaires was 75.8% and 91.2%, respectively, with a specificity of 53.8% and 24.6%. Regarding the 2ABN3M score, a sensitivity of 71.4% and a specificity of 44.6% were observed. Conclusions: The prevalence of sleep-disordered breathing in patients with HFrEF was high in our cohort and obstructive apnea predominated. Given the high sensitivity (91.2%) of the Stop-Bang questionnaire found in our study, it could be useful as a screening tool for TRS in this type of patient. The importance of investigating this pathology whose clinical presentation can be non-specific and remain underdiagnosed is highlighted.

Introdução: Os distúrbios respiratórios do sono (DRS) são altamente prevalentes em pacientes com insuficiência cardíaca (IC). A presença da síndrome da apneia obstrutiva do sono (SAOS) determina pior prognóstico nesses pacientes. Existem questionários destinados a avaliar a probabilidade de AOS, porém nenhum foi validado em pacientes com IC. O objetivo primário deste estudo foi estabelecer a prevalência de DRS em uma coorte de pacientes com IC e fração de ejeção reduzida (ICFEr) da Unidade Multidisciplinar de IC (UMIC). Como objetivo secundário, avaliar a utilidade dos questionários Stop-Bang, Berlin e 2ABN3M para triagem de SRT nesses pacientes. Metodologia: Estudo transversal, observacional, inclui a coorte ativa da UMIC, maiores de 18 anos com ICFEr, clinicamente estável e consentimento informado. Foram excluídos pacientes com deficiência cognitiva, neurológica ou auditiva com limitações na realização da entrevista. Pacientes com outros distúrbios do sono limitantes ou descontrolados, requisitos de oxigenoterapia domiciliar contínua, não entraram no estudo. Os questionários Berlin, Stop-Bang e 2ABN3M foram aplicados, classificando a população em grupos de alto risco, risco intermediário e baixo risco de apresentar DRS. Todos os pacientes foram submetidos à poligrafia respiratória (PR) ambulatorial. A estatística descritiva foi utilizada para caracterizar as variáveis ​​demográficas, medidas de tendência central e dispersão. Foi utilizado o software estatístico SPSS. Resultados: foram incluídos 387 pacientes, 248 homens (64,1%), com idade média de 63,5 ± 0,6 anos. A etiologia da IC foi isquêmica em 41,6% dos pacientes. O índice de massa corporal foi de 29,3 ± 0,3 kg/m2. FEVE foi de 34,2 ± 0,5, pro-BNP 1233,8 ± 137,6 pg/ml. Os resultados dos questionários mostraram que 52,1% (198) apresentaram alto risco de DRS de acordo com o questionário de Berlim. Com Stop-Bang, 35,9% (139) eram de alto risco, 42,1% (163) de risco intermediário e os restantes 22% (85) de baixo risco. Com a pontuação 2ABN3M, 62% (240) eram de alto risco. Foram realizados 156 polígrafos respiratórios (40,3% da população). O ponto de corte para definir a presença de apneia do sono foi considerado um IAH >15. 58,3% (91) dos pacientes apresentaram SRT. Destes, 95% apresentavam apnéia obstrutiva e 5% apnéia central com respiração Cheyne-Stokes periódica. Uma alta porcentagem (26%) apresentou IAH maior que 30. A sensibilidade dos questionários Berlin e Stop-Bang foi de 75,8% e 91,2%, respectivamente, com especificidade de 53,8% e 24,6%. Em relação ao escore 2ABN3M, observou-se sensibilidade de 71,4% e especificidade de 44,6%. Conclusões: A prevalência de distúrbios respiratórios do sono em pacientes com ICFEr foi alta em nossa coorte, com predominância de apneias obstrutivas. Dada a alta sensibilidade (91,2%) do questionário Stop-Bang encontrado em nosso estudo, ele pode ser útil como uma ferramenta de triagem para ERT nesse tipo de paciente. Ressalta-se a importância da investigação dessa patologia cuja apresentação clínica pode ser inespecífica e permanecer subdiagnosticada.

First report of Fusarium verticillioides causing safflower root rot in Sinaloa, Mexico.

Safflower cultivation is of great socioeconomic importance worldwide. Production is intended for the extraction of oil from the seeds. In 2021 Mexico ranked fifth in world production with approximately 52,553.28 tons (SIAP, 2021). In April 2022, in the north-central zone of Sinaloa, Mexico, diseased plants were reported in fields planted with safflower. Symptoms included chlorotic plants, necrosis and rot in vascular bundles, dwarfed plants and reflexed plants bent towards the ground. The disease caused estimated losses of 15% of seed production, with respect to the production obtained from the previous year in the safflower fields surveyed. Twenty-five plants with symptoms were sampled to isolate the pathogen. Plants were cut at the base of the stem near the roots and roots cut into 5 mm2 pieces. Tissue samples were superficially disinfected by immersing in 70% alcohol for 10 sec, 2% sodium hypochlorite for 1 min, washed in sterile water, and placed on potato dextrose agar (PDA) at 28 ºC for 7 days in the dark. Twelve monosporic isolates derived from the PDA culture were morphologically characterized. Abundant white aerial mycelium and small pink to dark violet pigments in the center of the culture were observed. From 10-day-old cultures grown on carnation leaf agar medium microconidia and macroconidia were produced. Microconidia were hyaline, had zero to two septa, and were oval or ellipsoidal, 4.6 to 14 x 1.8 to 4.2 µm (n = 40). The macroconidia were hyaline, were slightly curved with three to five septa, and measured from 26 to 69 x 3 to 6.1 µm (n = 40). No chlamydospores were observed. According to the morphological characteristics, the isolates were identified as Fusarium verticillioides (Leslie and Summerell, 2006). DNA was extracted from one isolate and the Translation Elongation Factor 1-α (EF1) gene was amplified and sequenced (O'Donnell et al. 2010). The sequence obtained from isolate FV3CARCULSIN with 645 base pairs was submitted to NCBI GenBank with accession number OQ262963. The BLAST search revealed 100% similarity with F. verticillioides isolate 13 (KM598773) (Lizárraga et al. 2015). Identification in FUSARIUM ID resulted in a 99.85% similarity with isolate F. verticillioides CBS 131389 (MN534047) (Yilmaz et al. 2021). A phylogenetic tree, made with sequences of the EF1 gene, revealed that FV3CARCULSIN was most closely related to F. verticillioides (100% bootstrap). Pathogenicity tests were carried out on safflower plants (cv. Oleico) grown in sterile vermiculite. Plants were inoculated with a conidial suspension (1 × 105 conidia/ml) obtained from FV3CARCULSIN grown on PDA for 7 days. A total of 45 plants were inoculated by drenching the roots with 20 ml of inoculum when the plants were 20 days old. Fifteen plants served as negative controls without inoculation. Plants were kept for 60 days in greenhouse conditions; however, after 45 days the plants began to die. The assay was conducted twice. Rotting and necrosis was observed in the roots of the plants. The pathogen was reisolated from the tissue of all the plants with symptoms and identified as F. verticillioides using morphological characteristics and EF1 sequences, completing Koch's postulates. No symptoms were observed in control plants after 60 days. This is the first report of root rot in safflower caused by F. verticillioides in Mexico. The fungus has been reported in maize (Figueroa et al. 2010), but it is unknown if it could be the same pathogen of safflower. Identification of the pathogen is important for implementing management methods to reduce yield losses and for additional studies on the impact of the disease on oil quality extracted from safflower seeds.

Auto-reporte de Periodontitis en diabéticos. Estudio transversal en Montevideo, Uruguay

Objetivo: Conocer la ocurrencia de periodontitis a partir de un cuestionario de auto-reporte en una población de diabéticos en Montevideo, Uruguay. Materiales y métodos: Fueron invitados los participantes del 1er Encuentro de Diabetes en Uruguay, con diagnóstico de diabetes según auto-reporte, con al menos 18 años de edad y que firmaron el consentimiento informado. En todos los casos, fue aplicado un cuestionario con ocho preguntas previamente validadas al español de forma de estimar la ocurrencia de la Periodontits además de identificar indicadores asociados. Resultados: Un total de 37 personas respondieron el cuestionario suministrado, en su mayoría correspondientes al sexo femenino y de 45 años de edad promedio. La ocurrencia de periodontits fue del 68% de los encuestados, no existiendo diferencias significativas para el tipo de diabetes y las franjas etarias consideradas. Sin embargo las personas que presentaban periodontits tuvieron menos dientes naturales (según auto-reporte) al ser comparados con quienes no tenían periodontitis (27.5 vs. 20.4, p=0.01). Conclusiones: Los resultados del estudio permiten apreciar una condición oral deficitaria en aquellos diabéticos con periodontitis auto-reportada debido a la ocurrencia elevada de la misma así como la menor cantidad de dientes naturales.

Objective: To determine the occurrence of periodontitis from a self-report questionnaire in a population of diabetics in Montevideo, Uruguay. Materials and methods: Participants of the 1st Diabetes Meeting in Uruguay, with a diagnosis of diabetes according to self-report, with at least 18 years of age and signed the informed consent, were invited. In all cases, a questionnaire with eight questions previously validated in Spanish was applied in order to estimate the occurrence of Periodontits in addition to identifying associated indicators. Results: A total of 37 people answered the supplied questionnaire, mostly corresponding to the female sex and an average age of 45 years. The occurrence of periodontitis was 68%, with no significant differences for the type of diabetes and the age groups considered. However, people with periodontitis had fewer natural teeth (according to self-report) when compared to those who did not have periodontitis (27.5 vs. 20.4, p = 0.01). Conclusions: The results of the study allow us to appreciate a poor oral condition in those diabetics with self-reported periodontitis due to its high occurrence as well as the lower number of natural teeth.

Risk Factors for Bronchiolitis Obliterans Syndrome after Initial Detection of Pulmonary Impairment after Hematopoietic Cell Transplantation.

Pulmonary chronic graft-versus-host-disease (cGVHD), or bronchiolitis obliterans syndrome (BOS), is a highly morbid complication of hematopoietic cell transplantation (HCT). The clinical significance of a single instance of pulmonary decline not meeting the criteria for BOS is unclear. We conducted a retrospective analysis in a cohort of patients who had an initial post-HCT decline in the absolute value of forced expiratory volume in 1 second (FEV1) of ≥10% or mid-expiratory flow rate of ≥25% but not meeting the criteria for BOS (pre-BOS). We examined the impact of clinical variables in patients with pre-BOS on the risk for subsequent BOS. Pre-BOS developed in 1325 of 3170 patients (42%), of whom 72 (5%) later developed BOS. Eighty-four patients developed BOS without detection of pre-BOS by routine screening. Among patients with pre-BOS, after adjusting for other significant variables, airflow obstruction (hazard ratio [HR], 2.0; 95% confidence interval [CI], 1.1 to 3.7; P = .02), percent-predicted FEV1 on decline (HR, .98; 95% CI, .97 to 1.0; P = .02), active cGVHD (HR, 7.7; 95% CI, 3.1 to 19.3; P < .001), peripheral blood stem cell source (HR, 3.8; 95% CI, 1.7 to 8.6; P = .001), and myeloablative conditioning (HR, 2.0; 95% CI, 1.1 to 3.5; P = .02) were associated with subsequent BOS. The absence of airflow obstruction and cGVHD had a negative predictive value of 100% at 6 months for subsequent BOS, but the positive predictive value of both factors was low (cGVHD, 3%; any obstruction, 4%; combined, 6%). Several clinical factors at the time of pre-BOS, particularly active cGVHD and airflow obstruction, increase the risk for subsequent BOS. These factors merit consideration to be included in screening practices to improve the detection of BOS, with the caveat that the predictive utility of these factors is limited by the overall low incidence of BOS among patients with pre-BOS.

Probióticos y enfermedad periodontal. Revisión de la literatura

RESUMEN: La enfermedad periodontal se clasifica en dos grandes grupos principales: gingivitis y periodontitis, desencadenadas por una alteración de la microbiota oral, que causa un aumento de microorganismos patógenos con respecto a los beneficiosos. Estos, en interacción con el hospedero y con los factores de riesgo del paciente, definirán una presentación clínica específica. Una de las estrategias que se propone como alternativa frente al uso de antibióticos y como coadyuvante del raspado y alisado radicular (RAR) para tratar las periodontitis, es la administración de probióticos. Los probióticos son denominados como microorganismos vivos que al ser administrados en cantidades adecuadas son capaces de ejercer una acción benéfica sobre la salud del hospedador. Por tanto, el objetivo de este trabajo fue describir el beneficio de los probióticos en la prevención y tratamiento de las principales enfermedades periodontales. Para ello, se realizó una búsqueda desde Enero del 2010 a Mayo del 2020 en Pubmed, Web of Science, SciELO, Science Direct y el Portal Timbó. Obteniéndose como resultado que los probióticos son capaces de reducir los parámetros clínicos y microbiológicos de dichas enfermedades y que pueden ser un valioso complemento en su prevención y tratamiento.

ABSTRACT: Periodontal disease is classified into two main groups: gingivitis and periodontitis, triggered by an alteration of the oral microbiota, which causes an increase in pathogenic microorganisms with respect to the beneficial ones. In interaction with the host and with the risk factors of the patient. They will define a specific clinical presentation. One of the strategies proposed as an alternative to the use of antibiotics and as an adjunct to scraping and root planning (RAR) to treat periodontitis, is the administration of probiotics. Probiotics are living microorganisms that, when administered in adequate amounts, are capable of exerting a beneficial action on the health of the host. Therefore, the objective of this work was to describe the benefit of probiotics in the prevention and treatment of the main periodontal diseases. For this, a search was carried out between 2010 and 2020 in PubMed, Web of Science, SciELO, Science Direct and the Timbó Portal. The results obtained showed that probiotics are capable of reducing the clinical and microbiological parameters of these diseases and that they can be a valuable complement in their prevention and treatment.

Laparoscopic vs open portoenterostomy in biliary atresia: a systematic review and meta-analysis.

Hepatoportoenterostomy remains the cornerstone of treatment for biliary atresia. Current employed techniques include laparoscopy and open surgery. This study aims to determine if either method provides an advantage. Following PRISMA guidelines, a systematic review was conducted. Nineteen studies were included. Mean operative time 34.98 (95% CI 20.10, 49.85; p ≤ 0.00001) was longer in laparoscopic while bleeding volumes - 16.63 (95% CI - 23.39, - 9.86; p ≤ 0.00001) as well as the time to normal diet - 2.42 (95% CI - 4.51, - 0.32; p = 0.02) were lower in the laparoscopic group. No differences were observed in mean length of stay - 0.83. Similar complication, transfusions, postoperative cholangitis 0.97, and transplant free survival rates 1.00 (0.63, 1.60; p = 0.99) were seen between groups. Laparoscopic portoenterostomy provides advantages on operative time and bleeding as well as to normal diet when compared to open procedures. Both procedures showed no differences in length of stay, complications, cholangitis, and importantly, native liver survival. Level of evidence: III.

Ibero-Panamerican Federation of Periodontics Delphi study on the trends in diagnosis and treatment of peri-implant diseases and conditions: A Latin American consensus.

BACKGROUND: The social diversity, heterogeneous culture, and inherent economic inequality factors in Latin America (LA) justify conducting a comprehensive analysis on the current status and future trends of peri-implant diseases and conditions. Thus, the aim of this Delphi study was to predict the future trends in the diagnosis and treatment of peri-implant diseases and conditions in LA countries for the year 2030. METHODS: A Latin American steering committee and group of experts in implant dentistry validated a questionnaire including 64 questions divided into eight sections. The questionnaire was run twice with an interval of 45 days, with the results from the first round made available to all the participants in the second round. The results were expressed in percentages and data was analyzed describing the consensus level reached in each question. RESULTS: A total of 221 experts were invited to participate in the study and a total 214 (96.8%) completed the two rounds. Moderate (65%-85%) to high consensus (≥ 85%) was reached in 51 questions (79.69%), except in the questions dealing with "prevalence", where no consensus was reached. High and moderate consensus was attained for all the questions in three fields (risk factors and indicators, diagnosis and treatment of peri-implant conditions and deficiencies, and prevention and maintenance). CONCLUSIONS: The present study has provided relevant and useful information on the predictions in the diagnosis and treatment of peri-implant diseases with a high level of consensus among experts. Nevertheless, there is still a lack of agreement in certain domains.

Delphi Project on the trends in Implant Dentistry in the COVID-19 era: Perspectives from Latin America.

AIM: To establish trends in Implant Dentistry in Latin America in the COVID-19 pandemic. MATERIAL AND METHODS: A steering committee and an advisory group of experts in Implant Dentistry were selected among eighteen countries. An open-ended questionnaire by Delphi methodology was validated including 64 questions, divided in 7 topics, concerning the various trends in dental implantology. The survey was conducted in two rounds, which provided the participants in the second round with the results of the first. The questionnaires were completed on August 2020, and the online meeting conference was held on September 2020. The final prediction was developed through consensus by a selected group of experts. RESULTS: A total of 197 experts from Latin America answered the first and second questionnaire. In the first round, the established threshold for consensus (65%) was achieved in 30 questions (46.87%). In the second round, performed on average 45 days later, this level was achieved in 47 questions (73.43%). Consensus was completely reached on the item "Diagnostic" (100%), the field with the lowest consensus was "Demand for treatment with dental implants" (37.5%). CONCLUSIONS: The present study in Latin America has provided relevant and useful information on the predictions in the education and practice of Implant Dentistry in the COVID-19 era. The consensus points toward a great confidence of clinicians in the biosecurity protocols used to minimize the risk of SARS-CoV-2 transmission. It is foreseen as an important change in education, with introduction of virtual reality and other simulation technologies in implant training.

Efectos psicosociales de la enfermedad periodontal en la calidad de vida de pacientes de la Facultad de Odontologia (UdelaR) Un estudio cuali-cuantitativo / Efeitos psicossociais da doença periodontal na qualidade de vida de pacientes da Faculdade de Odontologia (UdelaR). Um estudo qualitativo-quantitativo / Psychosocial impact of periodontal disease on the quality of life of patients of the school of dentistry (Udelar). A qualitative-quantitative study

Resumen Objetivos: Identificar los aspectos psicosociales de la enfermedad periodontal y su incidencia en la calidad de vida de las personas que la padecen. Métodos: Se realizó un estudio mixto cuanti-cualitativo en pacientes de la facultad de odontología UdelaR. Los instrumentos utilizados fueron: entrevista (semiestructurada) con base en la teoría fundamentada y la aplicación del cuestionario OHIP-14 (Oral Health Impact Profile) que mide el grado de afectación en la calidad de vida (modelo teórico de Locker). Resultado: Se identifican los factores psicosociales que presenta esta población, así como la afectación emocional y a nivel social que provoca el diagnóstico de enfermedad periodontal. Los resultados muestran una afectación en la calidad de vida de la población de 1,46 en una escala de 0-4, donde 4 es la máxima afectación. Las participantes femeninas mostraron mayor nivel de afectación en la calidad de vida (1,54) en comparación con los hombres (1,36). A mayor grado de instrucción más afectación en la calidad de vida. Conclusiones: Existe una limitación en el enfoque biomédico en la atención de pacientes odontológicos, y por tanto la necesidad de realizar un abordaje integral en pacientes con enfermedad periodontal. Los profesionales odontólogos deben tener un enfoque biopsicosocial en la atención debido a la complejidad que presenta la enfermedad periodontal.

Resumo Objetivos: Identificar os aspectos psicossociais da doença periodontal e sua incidência na qualidade de vida das pessoas que sofrem com a doença. Métodos: Foi realizado um estudo quantitativo e qualitativo misto. Os instrumentos utilizados foram: entrevista (semiestruturada), fundamentada na teoria fundamentada em dados, e aplicação do questionário OHIP-14 (Perfil de Impacto na Saúde Oral), que mede o grau de comprometimento da qualidade de vida (modelo teórico de Locker). Resultado: são identificados os fatores psicossociais que essa população apresenta, bem como a afetação emocional e social que causa o diagnóstico de doença periodontal. Os resultados mostram uma afetação na qualidade de vida da população de 1,46 em uma escala de 0-4, onde 4 é a afetação máxima. As participantes do sexo feminino apresentaram maior nível de comprometimento da qualidade de vida (1,54) em comparação aos homens (1,36). Quanto maior o grau de escolaridade, mais a qualidade de vida será afetada. Conclusões: A limitação da abordagem biomédica no cuidado de pacientes odontológicos e a necessidade de realizar uma abordagem abrangente em pacientes com doença periodontal são evidentes. Os profissionais de odontologia devem ter uma abordagem biopsicossocial ao atendimento devido à complexidade da doença periodontal.

Abstract Objectives: To identify the psychosocial factors of periodontal disease and their impact on the quality of life of patients. Methods: A mixed quantitative and qualitative study was conducted at the School of Dentistry, UdelaR. The instruments used were a semi-structured interview based on grounded theory and the application of the OHIP-14 (Oral Health Impact Profile) questionnaire that measures the degree of impairment of quality of life (Locker's theoretical model). Results: This population's psychosocial factors are identified, as well as the emotional and social effects of periodontal disease diagnosis. The results show a 1.46 impact on people's quality of life on a scale of 0-4, where 4 is the maximum impact. Women showed a higher level of impairment in quality of life (1.54) than men (1.36). The higher the educational level, the more the quality of life is affected. Conclusions The limitations of the biomedical approach to dental patient care and the need for a comprehensive approach in periodontal disease patients are clear. Dental professionals need a biopsychosocial care approach given the complexity of periodontal disease.

Aggressiveness and molecular characterization of Fusarium spp. associated with foot rot and wilt in Tomato in Sinaloa, Mexico.

Fusarium wilt is one of the main limiting factors for tomato production in Mexico. One thousand and fifty isolates were obtained from vascular tissues tomato plants showing wilt and yellowing symptoms in Sinaloa, Mexico. The pathogenic isolates were evaluated through phylogenetic analysis of the TEF-1α gene and ITS region, morphological markers and pathogenicity tests. Within the 15 pathogenic Fusarium isolates, 7 were identified as F. oxysporum and 8 as F. falciforme. Phylogenetic analysis of Fusarium oxysporum f. sp. lycopersici and Fusarium falciforme isolates confirmed that both populations are constituted by distinct phylogenetic lineages. The isolates showed differences in aggressiveness; F. falciforme was the most aggressive. Isolates of both complexes triggered similar aerial symptoms of yellowing and darkening of the vascular tissues in tomato plants. But only F. falciforme isolates triggered necrosis in the plant crowns. Morphological markers allowed differentiating isolates from distinct complexes but not differentiating between lineages.

Análisis bacteriano comparativo de cuadros de Periodontitis Crónica y Agresiva en una población muestra de Uruguay / Comparative bacterial analysis of chronic and aggressive periodontitis in a sample population from Uruguay

Objetivos: analizar comparativamente la prevalencia de ciertos patógenos periodontales en cuadros de periodontitis agresiva y crónica según la clasificación vigente al momento de los estudios, en 101 pacientes uruguayos. Métodos: Este análisis se basa en los trabajos de detección de patógenos periodontales en pacientes con periodontitis crónica y agresiva en Uruguay mediante metodología convencional y molecular 1,2. Ambos trabajos analizaron los mismos microorganismos y utilizaron las mismas técnicas de recuperación y análisis. Se estudiaron Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia y Fusobacterium nucleatum. Resultados: En los cuadros crónicos destacó F. nucleatum, T. forsythia y P.gingivalis. En los agresivos F. nucleatum y P. intermedia, y dentro de éstos en los generalizados una mayor proporción de P. gingivalis y T. forsythia y de A. actinomycetemcomitans en los localizados. Conclusiones: Se pudo constatar que se mantienen los patrones documentados en la bibliografía en Uruguay.3,4

Objectives: To compare the prevalence of certain periodontal pathogens in aggressive and chronic periodontitis in 101 Uruguayan patients according to the valid classification at the time the studies were conducted. Methods: This analysis is based on studies conducted to detect periodontal pathogens in patients with chronic and aggressive periodontitis in Uruguay using conventional and molecular methods. Both studies analyzed the same microorganisms and used the same recovery and analysis techniques. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia and Fusobacterium nucleatum were studied. Results: A higher prevalence of F. nucleatum, T. forsythia and P. gingivalis was detected in chronic cases, whereas higher rates of F. nucleatum and P. intermedia were observed in aggressive ones. Within the last one, a higher proportion of P. gingivalis and T. forsythia was detected in the generalized cases and A. actinomycetemcomitans in the localized ones. Conclusions: The patterns detected are in line with those included in the literature for our country

Detección de patógenos periodontales de una población con Periodontitis Agresiva en Uruguay mediante metodología convencional y molecular / Detection of periodontal pathogens in a Uruguayan population with aggressive periodontitis using conventional and molecular methods

Las enfermedades periodontales representan un importante problema de salud que afecta los tejidos de soporte de las piezas dentarias. Dentro de ellas, las Periodontitis Agresivas se caracterizan por su rápida progresión, agregación familiar, pacientes sistémicamente sanos1 subdividiéndose en localizadas y generalizadas según la extensión del cuadro. Los microorganismos juegan un papel importante en su etiopatogenia, entre los cuales se encuentran Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Fusobacterium nucleatum. El propósito de este trabajo fue estudiar cuáles de estos microorganismos estaba presente en 50 pacientes uruguayos con Periodontitis Agresiva. La detección se realizó con técnica convencional bacteriológica y PCR. En los cuadros generalizados se observó mayor prevalencia de F. nucleatum y P. intermedia seguido de P. gingivalis y T. forsythia. En los cuadros localizados destacaron P. intermedia, F. nucleatum y A. actinomycetemcomitans. En nuestro país se presentó una flora similar a los que figuran en otras localizaciones geográficas

Periodontal diseases are a major health problem affecting tooth-supporting tissues. Among them, aggressive periodontitis is characterized by rapid progression, family aggregation, systemically healthy patients, and is subdivided into localized and generalized according to the extent of the disease. Microbiota plays a major role in the etiopathogenesis of these diseases, including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Fusobacterium nucleatum. The aim of this work was to study the prevalence of these microorganisms in 50 Uruguayan patients with aggressive periodontitis. Detection was conducted with conventional bacteriological techniques and PCR. In the generalized disorders, a higher prevalence of F. nucleatum and P. intermedia was observed, although P. gingivalis and T. forsythia were also important. In the localized disorders, P. intermedia, F. nucleatum and A. actinomycetemcomitans were the main ones. A similar flora to other geographical locations was present in our country

Síndrome de Ascher. Clinica y tratamiento a propósito de un caso clínico / Ascher syndrome: clinical case care and treatment

Presentamos un paciente con "Sindrome de Ascher". Se trata de una rara entidad benigna, que es una anomalía congénita o adquirida de etiología desconocida. Clínicamente el Síndrome de Ascher, está compuesto por una tríada de signos clínicos: doble labio (siendo el superior el más frecuentemente involucrado), blefarocalasia y bocio no tóxico (agrandamiento tiroideo, no funcional y ausente en aproximadamente la mitad de los casos). Cuando la deformidad labial interfiere con la masticación o provoca groseras alteraciones estéticas, el tratamiento quirúrgico está indicado

We present a case report of a patient with Ascher Syndrome. It is a rare, benign disorder with few cases reported in the world. Clinically, it is an anomaly which may be either congenital or acquired, characterized by a triad: blepharochalasis, double lip (upper lip is involved more often than lower lip, although on occasion both may be involved), and nontoxic thyroid goiter. Surgical treatment may be indicated as it is a deformity that interferes with mastication and speech, and which might have aesthetic implications

Fibrina Rica en Plaquetas y Leucocitos en el tratamiento de defectos intra-óseos: Revisión Narrativa / Leucocyte and Platelet Rich Fibrin in the treatment of intra-bony defects. Narrative Review

RESUMEN: Diferentes técnicas quirúrgicas periodontales han surgido a lo largo del tiempo con el objetivo de lograr una regeneración periodontal y mejorar su predictibilidad. La Fibrina Rica en Plaquetas y Leucocitos (L-PRF) se ha posicionado como una alternativa para cumplir este objetivo, debido a que no requiere anticoagulantes en su preparación y muestra liberación sostenida de factores de crecimiento durante por lo menos 7 días. El objetivo de esta revisión narrativa es describir la evidencia disponible sobre el uso de L-PRF en defectos intra-óseos. Se realizó una búsqueda en las bases de datos MEDLINE y Cochrane Library, exploración manual y páginas web. De un total de 494 artículos recuperados, fueron seleccionados 12 publicaciones para esta revisión. Los resultados sugieren que L-PRF muestra beneficios al ser utilizada en el tratamiento periodontal regenerativo de defectos intra-óseos. Sin embargo, son necesarios ensayos clínicos con diseño metodológico estandarizado que permitan comparar L-PRF con biomateriales habitualmente empleados en el tratamiento de estos defectos.

ABSTRACT: Periodontal surgical techniques have emerged over time with the aim of achieving periodontal regeneration and improving its predictability. Leukocyte and Platelet-Rich Fibrin (L-PRF) has been proposed as an alternative, for not requiring anticoagulants in its preparation and for performing sustained release of growth factors for at least 7 days. The aim of this narrative review is to describe the available evidence on the use of L-PRF in periodontal intra-bony defects. An electronic and hand search was conducted in MEDLINE and Cochrane Library databases. Of 494 papers retrieved, 12 were selected for this review. The results suggest that even if L-PRF shows benefits when used in regenerative periodontal treatment of intra-bony defects, clinical trials with standardized methodological design are necessary to compare L-PRF with biomaterials usually used in these defects.

Epidemiología de las enfermedades periodontales en el Uruguay. Pasado y presente / Epidemiology of periodontal diseases in Uruguay: past and present

El objetivo del artículo fue realizar una revisión sobre la Enfermedad Periodontal en Uruguay. Fueron consultadas bases de datos internacionales (PUBMED, SCOPUS, EBSCO, SciELO). Paralelamente la búsqueda abarcó fuentes nacionales (Biblioteca Nacional de Odontología, Centro de documentación de la Facultad de Odontología, Ministerio de Salud Pública, Dirección Nacional de Sanidad de las Fuerzas Armadas), complementado por búsqueda manual. Los estudios hallados aportaron información epidemiológica útil, además de permitir un repaso histórico sobre conceptos de epidemiología, etio-patogenía y corrientes hegemónicas de la periodoncia. La Enfermedad Gingival representa la patología más prevalente, mientras que los cuadros periodontales destructivos afectan fundamentalmente a los adultos. La edad, el origen geográfico, la clase social y el hábito de fumar son indicadores fuertemente asociados con dichos trastornos. De la lectura pormenorizada de los artículos recopilados se plantean sugerencias a ser consideradas en los próximos relevamientos epidemiológicos.

This article aims to review periodontal disease in Uruguay. International databases (PUBMED, SCOPUS, EBSCO, SciELO) were consulted. The search also included national sources (National Library of Dentistry, Documentation Center of the School of Dentistry, Ministry of Public Health, National Directorate of Health of the Armed Forces) which were searched manually. The studies found provided useful epidemiological information and allowed us to conduct a historical review of epidemiology concepts, etiopathogenesis and hegemonic currents in periodontics. Gingival disease is the most prevalent disease, while destructive periodontal conditions mainly affect adults. Age, geographical origin, social class and smoking are indicators strongly associated with these disorders. From the close reading of the articles collected we can make suggestions to be considered in future epidemiological surveys

Prevalence and predictors for clinical attachment loss in adolescents in Latin America: cross-sectional study.

AIM: To describe the prevalence, severity and extension of clinical attachment loss (CAL) and to study the predictors in 15- to 19-year-old adolescents from high schools in the Latin America. MATERIALS AND METHODS: A cross-sectional, epidemiological study was performed. The sample included 1070 high school adolescents 15-19 years of age from Santiago de Chile (Chile), Buenos Aires, Córdoba, Mendoza (Argentina), Montevideo (Uruguay), Quito (Ecuador) and Medellín (Colombia). Calibrated examiners performed full mouth, six sites per tooth clinical examination. RESULTS: There was a response rate of 100%. The prevalence of CAL ≥3 mm in ≥1 site was 32.6%, probing pocket depth ≥4 mm was 59.3% and bleeding on probing (BoP) ≥25% was 28.6%. The logistic regression analysis adjusted for cities revealed that smoking (OR = 1.6), attending public school (OR = 2.3) and having a BoP ≥25% (OR = 4.2) were positively associated with CAL ≥3 mm in ≥ 1 site. CONCLUSION: Clinical attachment loss was prevalent in Latin America adolescents and it is associated with smoking, attendance public school and BoP.
