ABSTRACT

Objective: To contribute to early diagnosis of lesions in older patients, including potentially malignant lesions or those suspected of oral cancer by support of a web-based teledentistry platform. Material and Methods:This report contains information from 27 patients with oral lesions out of a total of 135 who received mobile dental care. Specialists who participated in the study involved professionals from the disciplines of periodontics, temporomandibular disorders, oral implantology, oral radiology, oral pathology and geriatrics. Referral consultations were carried out synchronously or asynchronously. Clinical information sent to oral pathology specialists involved a medical history and a traditional description of the lesion which considered size, color, limits, symptomatology, type of surface, consistency, location, and evolution. This information was complemented with a three-dimensional representation of the lesion, simulating an extra/intra oral clinical examination including a marker tool that allows to perform the anatomical-referencing of oral lesions. Results:27 consultations from 26 patients were evaluated for oral pathology lesions. 12 lesions were diagnosed as reactive, 5 were infectious lesions, 4 of vascular etiology, 3 pigmented lesions (amalgam tattoo and smoking-related melanosis) and 3 potentially malignant lesions. The most frequent location was the tongue with 8 cases, followed by the gingiva and jugal mucosa, each with 5 cases. Four lesions required biopsy and histopathological report. Conclusion: A teledentistry platform including digital representations of oral lesions using different digital markers, also associated with a mobile system to provide dental care, constitutes an excellent tool to treat patients that present oral lesions with potential cancer risk.

ABSTRACT

OBJECTIVE: To describe oncological and functional outcomes in patients treated with reconstructive organ-sparing surgery (OSS) for squamous cell carcinoma of the penis. Plastic reconstructive OSS of the penis with a split thickness skin graft has been proposed as a treatment option for penile cancer, with the objective being preservation of physiological voiding and sexual function without comprising oncological control. MATERIALS AND METHODS: Multicenter study reporting clinicopathological data of 57 patients with malignant lesions of the penis treated with OSS and plastic reconstructive surgery with split thickness skin graft from 2007 to 2019. Health related quality of life (HRQoL) was assessed with EuroQoL-5D-3L, urinary symptoms with the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms, and erectile function with the International Index of erectile function (IIEF)-5. RESULTS: Fifty-seven patients underwent OSS reconstructive surgery. Twenty underwent glans resurfacing, 23 partial penectomy, and 14 glansectomy. Median age was 55.1 years (interquartile range [IQR] 29-90), median follow-up 55.7 months (3-149). At the time of data analysis, 6 patients had died of Squamous Cell Carcinoma (SCC) (12.5%) and 10 (17.8%) had progressed. Kaplan-Meier estimates showed a 5-year survival rate of 87.5% and a 5-year progression-free survival of 83%. We assessed HRQoL and functional outcomes in 32 patients. EuroQol 5D-3L showed a mean health status of 82.5%, median Voiding score of the ICIQ-MLTUS was 4 (IQR 1-15), and median IIEF-5 19 (IQR 10.75-25). CONCLUSION: OSS of the penis remains a safe and viable option for the treatment of SCC, ensuring a favorable appearance of the penis, preserving urinary and sexual function, with good HRQoL and without comprising oncological safety in selected cases.

ABSTRACT

Verticillium wilt and leaf mottle of sunflower, caused by the fungus Verticillium dahliae (Vd) has become a major constraint to sunflower oil production in temperate European countries. Information about Vd from sunflower is very scarce despite genetics, molecular traits and pathogenic abilities of fungal strains affecting many other crops being widely known. Understanding and characterizing the diversity of Vd populations in those countries where sunflowers are frequent and severely affected by the fungus are essential for efficient breeding for resistance. In this study, we have analyzed genetic, molecular and pathogenic traits of Vd isolates affecting sunflower in European countries. When their genetics was investigated, almost all the isolates from France, Italy, Spain, Argentina, and Ukraine were assigned to vegetative compatibility group (VCG) 2B. In Bulgaria, Turkey, Romania, and Ukraine, some isolates were assigned to VCG6, but some others could not be assigned to any VCG. Genotyping markers used for Vd affecting crops other than sunflower showed that all the isolates were molecularly identified as race 2 and that markers of defoliating (D) and non-defoliating (ND) pathotypes distinguished two well-differentiated clusters, one (E) grouping those isolates from Eastern Europe and the other (W) all those from the Western Europe and Argentina. All the isolates in cluster W were VCG2B, while the isolates in cluster E belonged to an unknown VCG or to VCG6. When the host range was investigated in the greenhouse, the fungus was highly pathogenic to artichoke, showing the importance of farming alternatives in the management of Verticillium attacks. Sunflower genotypes were inoculated with a selection of isolates in two experiments. Two groups were identified, one including the isolates from Western Europe, Argentina, and Ukraine, and the other including isolates from Bulgaria, Romania, and Turkey. Three pathogenic races were differentiated: V1, V2-EE (Eastern Europe) and V2-WE (Western Europe). Similarly, three differentials are proposed for race identification: HA 458 (universal susceptible), HA 89 (resistant to V2-EE, susceptible to V2-WE) and INRA2603 (susceptible to V2-EE, resistant to V2-WE). The diversity found in Vd affecting sunflower must be taken into account in the search for resistance to the pathogen for European environments of sunflower production.

ABSTRACT

The goal of this work is to evaluate the influence of different pretreatments in the kinetics of enzymatic hydrolysis of sugarcane bagasse and to propose a reliable methodology to easily perform sensitivity analysis and updating kinetic parameters whenever necessary. A kinetic model was modified to represent the experimental data of the batch enzymatic hydrolysis of sugarcane bagasse pretreated with alkaline hydrogen peroxide. The simultaneous estimation of kinetic parameters of the mathematical model was performed using the Pikaia genetic algorithm using batch hydrolysis experimental data obtained with different enzymatic loads. Subsequently, Plackett-Burman designs were used to identify the kinetic parameters with the higher influence on the dynamic behavior of the process variables, which were re-estimated to describe experimental data of the hydrolysis of bagasse pretreated with phosphoric acid + sodium hydroxide. The methodology was accurate and straightforward and can be used whenever there are changes in pretreatment conditions and/or fluctuations in biomass composition in different harvests.

ABSTRACT

Introducción: El síndrome metabólico (SM) es factor de riesgo para mortalidad por enfermedad coronaria y diabetes mellitus. Se han propuesto nuevos marcadores de riesgo cardiovascular (RCV), con mejor capacidad pronóstica en la toma de medidas preventivas para disminuir la aparición o severidad de sus consecuencias. Objetivos: Establecer la prevalencia de SM y determinar el comportamiento de los factores de riesgo cardiovascular tradicionales y no convencionales entre hombres y mujeres de Bucaramanga, Colombia. Metodología: GÉNESIS es un estudio de cohorte prospectivo con evaluación en 2005 y 2010. Para la segunda fase, todos los participantes contestaron una encuesta semiestructurada, recibieron evaluación clínica, de presión arterial (PA) y parámetros antropométricos, así como toma de sangre periférica en ayunas para medición de coleste-rol, HDL, triglicéridos, glicemia, PCR, IL- 6, Apo A-I y Apo B. Resultados: Para la segunda fase se evaluaron 66 empleados. Se encontró una prevalencia de SM del 18.2%. La población masculina presentó los mayores valores de PA, glucemia, triglicéridos, Apo B y relación Apo B/Apo A-I, comparado con las mujeres. En el estudio de seguimiento se evaluaron 44 personas en dos momentos (2005 y 2010), donde la población femenina evidenció un aumento significativo del PA, niveles de colesterol, HDL y glucemia, así como descenso en los de PCR comparado con los hombres. Conclusión: El reconocimiento de los factores de riesgo tradicionales y no convencionales, y las diferencias de los mismos entre los géneros ayudaría a optimizar la estratificación del RCV y a futuro una mayor prevención de las enfermedades cardiovasculares.


Background: The metabolic syndrome (MS) is a risk factor for coronary heart disease and diabetes mellitus mortality. New cardiovascular risk markers have been proposed with better prognostic ability for taking preventive measures to decrease the occurrence or severity of their consequences. Objectives: To establish the prevalence of MS and to determine the behavior of traditional and no traditional cardiovascular risk factors of men and women from Bucaramanga, Colombia. Methodology: GENESIS is a prospective cohort study in 2005 and 2010 assessment. For the second phase, all participants completed a semistructured questionnaire, received clinical evaluation for blood pressure and anthropometric parameters and peripheral blood sampling for measurement of fasting glucose, cholesterol, HDL, triglycerides, CRP, IL-6, Apo AI and Apo B. Results: 66 employees were evaluated for second phase. The prevalence of MS was 18.2%. Among them, the male population had the highest values of waist circumference, glucose, triglycerides, Apo B and Apo B/Apo AI, compared with women. In Follow-up study, 44 people were assessed on two occasions (2005 and 2010); female population showed a significant increase in waist circumference, cholesterol, HDL and blood glucose levels, and decrease in CRP compared with men. Conclusion: The recognition of traditional and non-conventional risk factors, and the differences between genders would help to optimize cardiovascular risk stratification and therefore better prevention of CVD in the future.

ABSTRACT

Con la finalidad de estimar el flujo de proteína microbial hacia el duodeno (PMFD) en vacas lactantes a partir de la excreción urinaria de alantoína y establecer su relación con algunos parámetros del comportamiento productivo, se utilizaron ocho vacas (4 Holstein y 4 BON x Holstein) en diferente estado de lactancia (55 a 361 días en lactancia) que permanecieron bajo estabulación durante nueve días consumiendo pasto kikuyo (Pennisetum clandestinum), concentrado comercial y sal mineralizada. Durante los tres últimos días se registró la producción de leche (PL) y se tomaron muestras para analizar la concentración de proteína cruda (PCL) y nitrógeno ureico (NUL). En muestras del pasto ydel concentrado se determinó la materia seca (MS), la proteína cruda (PC), las cenizas (Cen), el extracto etéreo (EE), la fibra en detergente neutro (FDN), el nitrógeno insoluble en detergente neutro (PCIDN) y los carbohidratos no estructurales (CNE) y se estimó la concentración de nutrientes digestibles totales (NDT). Se determinó el consumo de materia seca (CMS) (11.63 ± 1.8 kg/vaca/d), el nitrógeno ingerido total (NIT) (249.9 ± 57.7 gr/vaca/d), la proteína degradable en rumen (PDR) del pasto y delconcentrado mediante la técnica in situ, y la relación CNE: PDR (1.1 ± 0.15 gr: gr). Los dos últimos días se recolectó la orina excretada por cada vaca (OR) donde se determinó la concentración de nitrógeno (NO) (23.08 ± 5.64 kg/vaca/d) y de alantoina (16.9 ± 15.1 g/d) a partir de la cual se estimó laPMFD (482.9 ± 509.7 g/vaca/d). Asimismo, con base en los NDT consumidos se estimó la PMFD (PMFDNRC) (769.80 ± 161.20 g/cow/d). Se establecieron relaciones mediante ecuaciones de regresión lineal entre el NO y la OR (p<0.03), la PMFD con el CMS (p<0.04) y con el NIT (p<0.04), y entre la PL (p<0.05), la PCL (p<0.03) y el NUL (p<0.06) con la PMFD. La relación con CNE: PDR no fue estadísticamente significativa (p>0.7). Los datos sugieren que la excreción de alantoína en orina sepuede usar para....

ABSTRACT

Los niveles de colesterol de baja densidad parecen ser la anormalidad con mayor repercusión en pacientes diabéticos tipo 2 por ser más aterogénico, incluso sin aumentos significativos. En muchos pacientes sólo el control glucémico y los cambios en el estilo de vida pueden lograr controlar los niveles de colesterol, pero no siempre hasta niveles deseables. La terapia agresiva para disminuir el colesterol de baja densidad en pacientes con alto riesgo de enfermedad coronaria disminuye los eventos coronarios agudos por lo que la reducción del colesterol de baja densidad, con aumento del colesterol de alta densidad, son el objetivo primario. Se ha propuesto como meta secundaria el control de factores asociados al síndrome metabólico (con el colesterol no HDL como meta), y como tercer objetivo la normalización de las lipoproteínas de alta densidad o de la relación colesterol/lipoproteínas de alta densidad. Las estatinas son los agentes de elección en el manejo de las dislipidemias en pacientes con diabetes mellitus tipo 2 sin hipertrigliceridemia significativa; disminuyen los niveles de colesterol de baja densidad y pueden administrarse como monoterapia o terapia combinada de acuerdo a los requerimientos del paciente. Los fibratos han probado su efectividad cuando habiéndose alcanzado las metas en los niveles de lipoproteínas de baja densidad, las otras no se han obtenido e incluso en pacientes con niveles de lipoproteínas de alta densidad aislado. El abordaje de la dislipidemia, se basa en el inicio temprano, agresivo y persistente del manejo farmacológico, para lograr reducir consecuencias en estos pacientes considerados equivalentes coronarios.


High levels of low density lipoprotein (LDL) cholesterol seem to be the abnormality with a greater repercussion among type 2 diabetic patients, due to the fact that they are more atherogenitic, by themselves, even with minor increases. In many patients only with the control of their glucemia and changing their life style, can they frequently manage to control the cholesterol levels to some extent but never reaching normal values? Many studies show that aggressive therapy to diminish the low density lipoprotein cholesterol in patients with high risk of coronary disease diminishes, significantly, the acute coronary events. This is one of the reasons why the reduction of LDL and the increase of the high density lipoprotein (HDL) cholesterol, is the main goal for handling of Dyslipidemia in these patients. The control of connected factors of the Metabolic Syndrome most be the second goal (with non-HDL cholesterol as objective); and as a third objective, has to be, the normalization of high density lipoproteins (HDL), as well as the relation cholesterol/high density lipoproteins. The statins are the election agents in the handling of Dyslipidemia in patients with significant type 2 diabetes mellitus without hipertrygliceridemia. They lower the cholesterol levels and the low density lipoprotein. They also can be given as single therapy. The fibrates have proven their effectiveness when LDL levels have been reached but no the others. The main goal to treat Dyslipidemia is based upon an early, aggressive and persistent pharmacologic intervention in order to reduce the bad prognosis in these patients, mainly in terms of potential coronary events.

ABSTRACT

Pullon y colaboradores en 1975 describieron los seis primeros casos de esta lesión en pacientes con un rango de edad comprendido entre los 11 hasta los 42 años, cinco de los cuales eran caucásicos y uno de raza negra (1). Hasta junio de 1993, aparecen en la literatura 26 casos adicionales (2). El Tumor Odontogénico Escamoso (TOE) es una lesión benigna, relativamente rara, que se cree originada en la transformación neoplástica de los restos epiteriales de Malassez o de los restos de la lámina dental. Puede ser multifocal y tener un cierto potencial agresivo si no es tratada en sus estadíos iniciales. El TOE suele presentarse en posición anterior respecto a los molares y se distribuye aproximadamente por igual entre la mandíbula. Las lesiones se detectan al principio como tumefacciones indoloras de crecimiento lento o bien como incremento incremento local de la movilidad de algunos dientes. Radiográficamente presenta forma triangular o semilunar, radiolúcida siendo las lesiones uniloculares de pequeño diámetro, mientras que las de mayor tamaño son multiloculares con borde radiopaco mal definido. Afecta a personas de cualquier edad con un pico de incidencia en la tercera década y la distribución entre sexo y raza es de difícil definición. (3.4). Microscópicamente la lesión está compuesta de nidos de epitelio escamoso estratificado de apariencia benigna sobre un fondo de tejido conectivo fibroso con células maduras. Las islas epiteriales asumen varias formas y tamaños presentando una capa basal conformada por células cuboidales de aspecto inactivo y carentes de empalizada. Muchos de los islotes epiteriales tienen áreas centrales de formación microquística, mientras que otros contienen estructuras calificadas esféricas o de forma irregular; calcificaciones similares pueden encontrarse en el conectivo. Adicionalmente se ha observado queratinización individual de las células y perlas de queratina o paraqueratina, (3,4). El tratamiento de elección es extirpación o curetaje de la lesión; sin embargo la eliminación superficial del TOE sin alcanzar hueso subyacente o el ligamento periodontal, suele provocar recurrencia (3,5). Esta publicación agrega un nuevo caso para la literatura haciendo énfasis en la importancia de un correcto diagnóstico clínico, radiográfico e histopatológico y un plan de tratamiento adecuado.
