ABSTRACT

El fibro-odontoma ameloblástico (FOA) es una neoplasia odontogénica benigna poco frecuente que afecta a los huesos maxilares. Posee un componente de tejido epitelial y ectomesénquima, por lo que hasta hace un tiempo era incluido dentro de la clasificación de tumores odontogénicos de origen mixto. Actualmente estas lesiones no están incorporadas en la última clasificación de los tumores odontogénicos y huesos maxilofaciales de la organización mundial de la salud y son consideradas como un odontoma en desarrollo. Clínicamente se presenta con mayor frecuencia en mandíbula y asociado a la falta de erupción de un diente. Presentamos el caso clínico de un niño de 6 años de edad que acudió a nuestro servicio maxilofacial por la no erupción de un diente temporal mandibular. El cuadro clínico y las investigaciones confirmaron la hipótesis diagnóstica de FOA con una impactación del segundo molar temporal inferior izquierdo hacia el margen basilar mandibular y el germen dentario del premolar por sobre la corona del diente retenido.


Ameloblastic fibro-odontoma (AFO) is a rare benign odontogenic neoplasm that affects the maxillary bones. It possesses both an epithelial and ectomesenchymal component, for which it was previously included in the classification of mixed odontogenic tumors. The AFO is currently not included in the latest classification of odontogenic and maxillofacial bone tumors, and is considered a developing odontoma. Clinically, it predominantly manifests in the mandible, in frequent association with the lack of eruption of a tooth. In this article, the authors present a case of a 6 year old boy with the query of an unerupted primary mandibular tooth. Both the clinical examination and the subsequent investigation confirmed the diagnostic hypothesis of an AFO with subsequent impaction of the primary left mandibular second molar, which was displaced against the base of the mandible, and the tooth germ for the left mandibular second premolar positionedover the crown of the retained tooth.

ABSTRACT

Aquellos casos en que se excede la fórmula dentaria normal primaria de 20 dientes o definitiva de 32 dientes se conocen como dientes supernumerarios o hiperodoncia. Los supernumerarios se pueden presentar de manera única o múltiple y de forma heteromórfica o eumórfica. El supernumerario más prevalente es el mesiodens, se da más en hombres, en dentición permanente y en el maxilar. Su etiología no está confirmada, pero puede deberse a una hiperactividad de la lámina dental. El tratamiento varía de acuerdo a cada paciente según si está afectando a la dentición normal o no y el desarrollo que tengan las estructuras dentarias. El siguiente reporte de caso habla de un paciente de 6 años, no sindrómico, en donde se presentó con un mesiodens erupcionado y se encontraron más supernumerarios gracias a la radiografía complementaria.


Those cases in which the primary normal dental formula of 20 teeth or the final one of 32 teeth is exceeded are known as supernumerary teeth or hyperdontia. The supernumeraries can be presented in a single or multiple way and in a heteromorphic or eumorphic way. The most prevalent supernumerary is the mesiodens, it occurs more in men, in the permanent dentition and in the maxilla. Its etiology is not confirmed, but it may be due to hyperactivity of the dental lamina. The treatment varies according to each patient depending on whether it is affecting the normal dentition or not and the development of the dental structures. The following case report talks about a 6-year-old, non- syndromic patient, who presented with an erupted mesiodens and more supernumeraries were found thanks to the complementary radiography.

ABSTRACT

Resumen Introducción: El año 2016, el Hospital Dr. Félix Bulnes Cerda (HDFBC) implementó el tamizaje obligatorio de anticuerpos anti Trypanosoma cruzi, para pesquisar nuevos casos de la enfermedad de Chagas (ECH) en mujeres embarazadas y recién nacidos (RN) y brindar tratamiento antiparasitario oportuno. Ello, porque la transmisión transplacentaria de T. cruzi continúa siendo un importante problema de salud pública. Objetivo: Presentar la información epidemiológica generada luego de la implementación del cribado de la ECH en el HDFBC del SSMOCC, al cabo de dos años de iniciada su operación. Material y Métodos: Cribado por inmunoquimioluminiscencia (IQLU), confirmación por IFI, ELISA y/o western blot. Seguimiento de RN: mediante RPC, IFI, ELISA e IQLU. Resultados: Entre abril de 2016 y julio de 2018 se analizó un total de 14.012 muestras de pacientes; 62 resultaron reactivas (0,53% seropositividad) y 28 fueron confirmadas positivas (prevalencia de 0,2%). Del total, 11.780 fueron de mujeres gestantes (n: 41 casos reactivos y 10 confirmadas con ECH), con prevalencia de 0,085%. Los restantes 18 casos positivos fueron usuarios no gestantes, con sospecha clínica de ECH y casos de estudios familiares, mostrando una prevalencia de 0,81%. El seguimiento a 10 RN y lactantes hijos de madres chagásicas descartó la transmisión transplacentaria Completaron tratamiento con nifurtimox 30% de las madres. Discusión: La implementación del programa en el HDFBC cumple los objetivos de cribado, pesquisa y diagnóstico de la ECH así como el seguimiento y tratamiento oportuno del RN. La prevalencia de 0,085% de la ECH en la población gestante como la de 0,2% en población total son significativamente menores (p-valor < 0,01) que la prevalencia de 0,7% reportada (año 2016) para la Región Metropolitana (RM); sugerimos que es consecuencia de la implementación del programa nacional y local. La transmisión congénita de 0% es acorde a la tasa de [0,91 x 10.000] reportada el 2017 para la RM. En base al aprendizaje adquirido, durante el desarrollo de la investigación, se entrega sugerencias para aportar al funcionamiento del programa.


Abstract Background: In 2016, the Hospital Dr. Félix Bulnes Cerda (HDFBC) implemented the mandatory screening of anti Trypanosoma cruzi antibodies in pregnant women, thus complying with national regulations to detect new Chagas disease cases (CHD) in mother and child, whose early detection mediates timely pharmacological treatment. This, because the congenital transmission continues the main active transmission mechanisms of T. cruzi and a major public health problem for the country. Aim: To present the epidemiological information generated after the implementation of the ECH screening in the SSFCC HFBC, two years after its operation began. Methods: Screening test: inmunequimioluminiscence (IQLU), certification by IFI, ELISA and/or western blot. Follow up of newborn infants with PCR, IFI, ELISA and IQLU. Results: Between April 2016 and July 2018, 14.012 subject's samples were examined of which 62 resulted reactive (0.53% seropositivity) in the total studied population where 28 patients resulted positive for CHD, which corresponds to a 0.2% prevalence. Of the total population, 11.780 were pregnant women, of these 41 were reactive and 10 were confirmed with CHD thus showing a prevalence of 0.085%. The other 18 positive cases of non-pregnant patients corresponded a prevalence of 0.81%. Also, 10 newborn and infant children of mothers with CHD were followed up. In all, congenital transmission (0%) was ruled out. Nifurtimox treatment of the mothers were completed in 30% of them. It is concluded that the implementation of the program in the HDFBC fulfills the objectives of screening, detection and diagnosis of CHD, so as the timely follow-up and pharmacologic treatment of the newborn. The 0.085% prevalence of CHD in pregnant women as the 0.20% in total population are significantly lower (p-valor < 0.01) than the 0.7% reported in 2016 for the Metropolitan Region (MR), a fact that we suggest is a consequence of the national program implementation. Likewise, the 0% transplacental transmission is accorded to the rate of 0.91 x 10.000 live births reported in 2017 for the MR. Based on the learning acquired during the development of the research, recommendations are given to contribute to the operation of the program.

ABSTRACT

ABSTRACT Objectives. To determine Neospora caninum seroprevalence in nonvaccinated dairy cattle from the Northern plains of Antioquia. Materials and methods. A cross-sectional study was conducted to determine the prevalence of neosporosis in a major dairy area of Colombia. Blood samples were collected from 1003 dairy cattle in 29 herds located in the municipality of San Pedro de los Milagros, in Antioquia. N. caninum antibody levels were measured by an enzymatic immunoassay (ELISA) and the results classified as positive or negative. Results. Seropositive cattle were observed in all herds, with a prevalence ranging from 7 to 97% and a mean (±S.E) of 37.1% (±4.2). The distribution of seropositive animals by age groups of <1, 1-2, 2-3 and ≥3 years old was 25.5, 30.3, 46.1 and 39.1%, respectively. Conclusions. There is a high seroprevalence of N. caninum in the main dairy cattle area of Antioquia. The large variation among herds suggests the presence of mayor risk factors whose identification would be essential to establish control programs. Considering that any seropositive cow has a greater risk to abort than uninfected mates, future studies should address the epidemiology of abortions that can be attributed to neosporosis and the type of control strategies that could be implemented.


RESUMEN Objetivos . Determinar la seroprevalencia de Neospora caninum en ganado lechero sin vacunar del altiplano Norte de Antioquia. Materiales y métodos . Se realizó un estudio transversal para determinar la prevalencia de neosporosis en bovinos de la principal zona lechera antioqueña. En Mayo-Junio del 2014 se recolectaron muestras de sangre de 1003 bovinos en 29 hatos ubicados en el municipio de San Pedro de los Milagros, en Antioquia. Los niveles de anticuerpos de N. caninum se midieron mediante un kit de inmunoensayo enzimático (ELISA) y los resultados se clasificaron como positivos o negativos. Resultados. Se observaron bovinos seropositivos en todos los hatos, con una prevalencia entre el 7 y 97%, y una media (±SE) del 37.1% (±4.2). La distribución de los animales seropositivos por grupos de <1, 1-2, 2-3 y ≥3 años de edad fue del 25.5, 30.3, 46.1 y 39.1%, respectivamente. Conclusiones. Se detectó una alta tasa de seroprevalencia de N. caninum en la principal zona de ganado lechero de Antioquia. La gran variación entre hatos apunta a que existen factores de riesgo cuya identificación sería esencial a la hora de instaurar programas de control. En vista de que cualquier vaca seropositiva tiene un mayor riesgo de abortar que congéneres no infectados, los próximos estudios deberían abordar la epidemiología de abortos atribuible a neosporosis previo a establecer cualquier plan de control.

ABSTRACT

Background: The intensity of conditioning chemotherapy and radiotherapy in hematopoietic stem cell transplantation (HSCT) varies according to several factors including the patient’s age, pre-existing conditions and performance status. Myeloablative conditioning (MA) increases transplant related mortality and reduces survival in older patients. Reduced intensity conditioning (RIC) is a good option for these patients. Aim: To report our experience with HSCT in patients of different ages with acute leukemia. Material and Methods: Retrospective analysis of 115 allogeneic HSCT performed in patients with acute myeloid or lymphoblastic leukemia. Results: We analyzed the cohort of patients in groups according to age at transplantation: younger than 40 years (n = 74), 41 to 50 years (n = 25) and older than 51 years of age (n = 16). Overall survival (OS), Disease free survival (DFS) and relapse at five years were similar in both groups of patients younger than 50 years (OS 40 and 44% respectively, DFS 38 and 42% respectively and relapse 40% and 34% respectively, p = NS). Patients over 51 years had a five years OS of 12%. However when we analyzed those patients by date and conditioning we found that patients who were treated with MA regimens in the first decade of the transplant program (before 2000) had lower OS compared to those treated after 2000 with RIC (five years OS 49% and 12% respectively, p < 0.01). No significant differences in terms of OS, recurrence or incidence of graft-versus-host disease were found when comparing groups under 40 years, between 41 and 50 years and older than 51 years treated only with RIC. Conclusions: RIC provides the possibility of HSCT in older patients with rates comparable to those obtained in younger patients successfully treated with MA conditioning.

ABSTRACT

Increased cardiovascular risk factors in young women merit knowing their nutritional profile. The objective of this study was to determine the food consumption of 50 volunteer college students enrolled in physical education (PE), early childhood education (ECA) and nutrition and dietetics (NAD) at the University of Playa Ancha, Valparaiso, Chile. A food frequency questionnaire was used to measure critical nutrient intake (sodium, sugars, saturated fatty acids, trans-fatty acids, cholesterol). Cardiovascular risk factors like alcohol intake were also measured as well as protective nutrients intake (mono and polyunsaturated fatty acids, water, dietary fiber). Consumption frequency was ranked high, moderate and low. Critical and protective nutrients were compared with the Chilean Dietary Guidelines 2013. Results: PE students' diet was high in sodium and dietary fiber; PE and EPA diet was high in added sugars and low in water; the diet of all groups was low in mono and polyunsaturated fatty acids, moderate in saturated fatty acids, trans-fatty acids and cholesterol, and low in alcohol. We conclude that the diets do not meet the recommendations of the Dietary Guidelines.


El aumento de los factores de riesgo cardiovascular en mujeres jóvenes amerita conocer su perfil nutricional. El objetivo del presente estudio fue conocer el consumo alimentario de 50 universitarias voluntarias de educación física (EFI), educación parvularia (EPA) y nutrición y dietética (NYD) de la Universidad de Playa Ancha, Valparaíso, Chile. Se usó un cuestionario de frecuencia para conocer consumo de nutrientes críticos (sodio, azúcares, ácidos grasos saturados, trans, colesterol y además de alcohol, factor riesgo cardiovascular) y protectores (ácidos grasos protectores mono y poliinsaturados, agua, fibra dietética). La frecuencia del consumo se clasificó en alto, moderado, bajo. Los nutrientes críticos y protectores fueron comparados con las guías alimentarias de Chile 2013. Resultados: EFI, fue alto en sodio y fibra dietética; EFI, EPA alto en azúcares agregados y bajo en agua. EFI, EPA NYD estuvieron bajos en ácidos grasos mono y poliinsaturados, moderado en ácidos grasos saturados, trans y colesterol y el alcohol bajo en los tres grupos. Lo observado, no consigue las recomendaciones de consumo de las guías alimentarias.

ABSTRACT

El estudio de predictores de rendimiento académico presenta gran relevancia en el área de la salud. El objetivo de este trabajo fue evaluar la relación entre el puntaje de Prueba de Selección Universitaria (PSU) y notas de enseñanza media (puntaje nota de enseñanza media) en la asignatura de Morfología en alumnos de primer año de odontología, en la Universidad de los Andes. Estudio descriptivo con 312 estudiantes admitidos en el primer año de la carrera de odontología de la Universidad de los Andes de Chile, de forma regular y que terminaron el año universitario sin deserción los años 2005 a 2008 y 2010. Las variables estudiadas fueron género, promedio puntaje de notas de enseñanza media, puntaje PSU, tipo de colegio de procedencia según sistema de financiamiento (municipal, particular subvencionado y particular) y nota final de la asignatura de morfología de los alumnos del primer año de estudio, en la carrera de odontología. De los 312 alumnos, la mediana de PSU, notas de enseñanza media y nota de morfología fueron 692,6, 702 y 4,4 respectivamente. Del total de la muestra, 221 alumnos (71%) correspondieron al sexo femenino. Del total de la muestra, 290 alumnos (93%) provenían de colegios particulares, 15 alumnos (5%) de colegios particulares subvencionados y 6 alumnos (2%) de colegios municipales. La relación entre puntaje nota de enseñanza media y nota de morfología muestra una correlación de 0,35 (Rho de Spearman, valor-p <0,0001), y puntaje de PSU con nota de Morfología una correlación de 0,39 (Rho de Spearman, valor-p <0,0001). Existe asociación entre nota morfología, puntaje de notas de enseñanza media y PSU, de tal manera, que los mejores puntajes de nota de enseñanza media y PSU, muestran mejor rendimiento en la asignatura de morfología.


The study of predictors of academic performance is of great importance in the area of health. The objective of this study was to assess the relationship between PSU (University selection admission scores) and Secondary Education (High school grade point average score) in the freshmen morphology course in dentistry, at the Universidad de los Andes. A descriptive study of 312 students admitted to the first year of dental school at the Universidad de los Andes in Chile, on a regular basis and who have completed the academic year without dropping out, the years 2005-2008 and 2010. The variables studied were sex, grade point average in high school, PSU score, type of school of origin as financing system (municipal, private subsidized and private) and final grade received in morphology for dentistry students during their freshmen year. Of the 312 students, the median PSU, high school grades and morphology were as follows: 692.6, grade 702, and 4.4 respectively. Of the total sample, 221 students (71%) were female. Of the total sample, 290 students (93%) had attended private schools, 15 students (5%) private subsidized schools and 6 students (2%) municipal schools. The relationship between scores and high school grade point average and grade attained in the morphology course, shows a correlation of 0.35 (Spearman rho, p-value <0.0001) and PSU score with the morphology course grade, a correlation of 0.39 (Spearman rho, p-value <0.0001). There is a relationship between morphology grade scores, high school grades and university selection test scores, indicating that the best high school grades and university selection scores show better student performance in the subject of morphology.

ABSTRACT

Introducción: La calidad de vida y estado nutricional del lactante con alergia a la proteína de leche de vaca (APLV) pueden comprometerse sin un adecuado diagnóstico y tratamiento oportuno. Objetivo: Describir síntomas digestivos, antecedentes familiares y perinatales, estado nutricional y respuesta de lactantes < 12 meses con APLV entre junio de 2007 y agosto de 2011. Pacientes y Método: Estudio retrospectivo, descriptivo en lactantes < 12 meses de edad que consultan por sospecha de APVL. Se investigaron antecedentes familiares, perinatales y características clínicas. Se excluyó a los casos sin prueba de alimentación o provocación abierta, o cuyo motivo de consulta correspondió a otra patología. Se usó el programa STATA especial edición 11,1 para el análisis estadístico. Se consideró estadístico y significativo un p < 0,05. Resultados: Se diagnosticaron 40 lactantes (57,5 por ciento varones), edad 3,0 +/- 0,4 meses, clínica de 2 +/- 0,3 meses de: vómito/regurgitación: 20, diarrea sanguinolenta: 8, falla en el crecimiento: 4, cólico/irritabilidad: 4, deposición normal con sangre en 3. Los antecedentes familiares y perinatales fueron ingesta de biberón en la 1ª semana de vida: 35, madre > 30 años: 31 casos, atopia en 2 familiares (padres/hermanos): 28, parto por cesárea: 27. Al seguimiento de 14 +/- 1,4 meses, 19 respondieron a fórmula ampliamente hidrolizada +/- seno; 19 a fórmula de aminoácidos +/- seno y un paciente lactancia exclusiva. El Z-score de P/E:-1,05 +/- 1,28; T/E: -0,96 +/- 1,60; IMC: -0,61 +/- 1,03 en primera consulta, mejoró al año: P/E: -0,15 +/- 1,24; T/E: -0,29 +/- 1,14 e IMC: -0,04 +/- 1,20 (p < 0,05), independiente de la fórmula (p = NS). Veintitres toleraron leche entera al año. Conclusiones: En este estudio los síntomas predominantes al inicio de los pacientes con APLV fueron vómitos, regurgitación y diarrea sanguinolenta. Entre los antecedentes destacan la exposición temprana a PLV, atopia familiar y parto por cesárea...


Introduction: Quality of life and nutritional status of infants with cow's milk protein allergy (CMA) can be compromised without a proper diagnosis and treatment. Objective: To describe digestive symptoms, family and perinatal history and nutritional status of < 12 month infants with CMA between June 2007 and August 2011. Patients and Method: A retrospective and descriptive study in < 12 month old infants suspecting CMA was performed. Family history, perinatal and clinical characteristics were studied. Cases without food test or open challenge test, or whose reason for consultation corresponded to other pathology were excluded. The program STATA 11.1 was used for statistical analysis and p < 0.05 was considered statistically significant. Results: 40 infants (57.5 percent boys), age 3 +/- 0.4 months and history of 2 +/- 0.3 months presenting the following: 20 of them (50 percent, vomiting/regurgitation; 8 (20 percent, bloody diarrhea; 4 (10 percent) failure to thrive; 4 (10 percent), colic/irritability and bloody normal deposition was present in 3 individuals (7.5 percent). Family and perinatal history: 35 (87.5 percent were bottle-fed during the first week of life; 31 (77.5 percent) had > 30 year old mothers; 28 (70 percent described 2 family members (parents/siblings) with atopy; 27 (67.5 percent were delivered via cesarean. At the 14 +/- 1.4-month follow-up, 19 (47.5 percent responded to extensively hydrolyzed formula +/- breastfeeding; 19 to amino acid formula +/- breastfeeding and one patient to breastfeeding exclusively. The Z -score for P/E was: -1.05 +/- 1.28; T/E: -0.96 +/- 1.60; BMI: -0.61 +/- 1.03 in the first consultation; after a year, scores improved: P/E: -0.15 +/- 1.24; T/E: -0.29 +/- 1.14 and BMI: -0.04 +/- 1.20 (p < 0.05), independent from formula (p = NS). 23 (74 percent) tolerated whole milk when reached a year old. Conclusions: In this study, the predominant early symptoms were...

ABSTRACT

La Enteritis Eosinofílica Idiopática (EEI) es una enfermedad de causa desconocida, reportada en los humanos y en varias especies animales. En el bovino se ha aceptado desde 1998 como una entidad poco común, con escasos reportes a nivel mundial. En este estudio se documenta una vaca que presentó inflamación intestinal de curso crónico, diagnosticada como EEI con base en el análisis de los hallazgos clínicos, histopatológicos y la exclusión de otras enfermedades intestinales. Esta comunicación constituye el primer reporte en Colombia de esta condición en el bovino y tiene como objetivo describir los hallazgos clínicos y anatomopatológicos encontrados y discutir sus posibles causas y mecanismos de enfermedad. Debido a que no se identificaron agentes infecciosos en el caso estudiado y a que la vaca presentó concomitantemente neoplasias, se postula como mecanismo de enfermedad más probable, el síndrome hipereosinofilia paraneoplásica.


Idiopathic Eosinophilic enteritis (IEE) is a disease of unknown cause reported in humans and various animal species. In cattle it has been accepted since 1998 as a rare entity, with few reports worldwide. This study documents the process of a cow that showed intestinal inflammation of chronic characteristics, diagnosed with IEE based on clinical and histopathological analysis as well as the exclusion of other intestinal diseases. This account is based on the first report of this condition in Colombian cattle and aims to describe clinical and anatomopathologic findings and the discussion of its possible causes and mechanisms of the disease. Because no infectious agents were identified in the case studied, and the fact hat the cow presented related neoplasms, the most probable mechanism of disease presented is the, paraneoplastic hypereosinophilia syndrome.

ABSTRACT

Objetivo: Determinar si la condición clínica periodontal materna, el índice de masa corporal (IMC) y su variación durante el embarazo, se asocian con marcadores de inflamación sistémica: interleuquina-6 (IL-6), factor de necrosis tumoral alfa (TNF-) y proteína C reactiva (PCR) a nivel plasmático. Material y Método: Estudio clínico que analizó una cohorte de 56 embarazadas entre 18 y 38 años de edad (promedio 27.9 +/- 7.04 años), derivadas de la unidad de medicina perinatal en el centro de salud docente asistencial (CESA) de la Universidad de los Andes. Todas ellas consintieron voluntariamente su participación en el estudio. En cada trimestre de embarazo, se les realizó un examen periodontal completo, consistente en la determinación de los niveles de inserción clínica, profundidad al sondaje, índice de higiene y sangrado en seis sitios por cada pieza dentaria, excluyendo terceros molares. Adicionalmente, en cada control se obtuvieron muestras de sangre periférica para la determinación de los mediadores proinflamatorios mediante técnica de ELISA. El diagnóstico periodontal y los niveles de mediadores inflamatorios fueron relacionados con la variación del IMC durante el embarazo. Resultados: Las embarazadas con periodontitis crónica presentaron una mayor variación y aumento del índice de masa corporal (p=0.039) y niveles de IL-6 (p=0.026) en comparación con las mujeres embarazadas con gingivitis. Conclusiones: En esta serie de pacientes, se demostró una asociación entre el diagnóstico clínico de periodontitis durante el embarazo con un aumento plasmático de IL-6, así como también una asociación entre un aumento del IMC con los niveles plasmáticos de PCR.


Objective: To determine if maternal periodontal clinical status, body mass index (BMI) and its variation during pregnancy are associated with increased levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-) and C-reactive protein (CRP) in plasma. Material and Methods: This clinical study included a total of 56 pregnant women between 18 and 38 years old (mean 27.9 +/- 7.04 years), referred from perinatal medicine unit at health care center Universidad de los Andes. All pregnant patients consented to voluntarily participate in the study. In each trimester of pregnancy, they underwent a complete periodontal examination, involving the determination of clinical attachment levels, probing depth, bleeding and hygiene index at six sites of each tooth, excluding third molars. Additionally, in each clinical check, peripheral blood samples were taken for determination of pro-inflammatory mediators with ELISA immunoassay. Periodontal diagnosis and inflammatory mediators were the variables analyzed in relation to changes in BMI during pregnancy. Results: Pregnant women with chronic periodontitis had an increase and more variation of BMI (p=0.039) and higher levels of IL-6 (p=0.026) in comparison with pregnant women with gingivitis. Conclusions: In this series of pregnant patients the clinical diagnosis of periodontitis, with an increase in BMI are associated with increased plasma levels of IL-6 and CRP.

ABSTRACT

Objetivo. Analizar retrospectiva y sistemáticamente los hallazgos clínicos e histopatológicos de paratuberculosis bovina Mycobacterium avium subsp. Paratuberculosis (MAP). Los datos fueron obtenidos en diferentes momentos durante un periodo de 8 años (2000-2008) en un hato lechero en Colombia. Materiales y métodos. Se analizó la información documental en 5 casos compatibles con paratuberculisis bovina, así como la información procedente de otros estudios efectuados en el hato sobre la enfermedad realizados paralelamente en el periodo 2000-2008. Resultados. Los 5 animales afectados, presentaron diarrea crónica intermitente, disminución en la producción de leche, enflaquecimiento progresivo, apetito normal, consumo aumentado de agua y constantes fisiológicas normales. A la necropsia se observó engrosamiento de la mucosa intestinal del íleon y de la porción proximal del intestino grueso con múltiples levantamientos y depresiones, que no desaparecían al estirar el tejido. Los vasos sanguíneos mesentéricos se encontraron dilatados y congestivos. Los ganglios linfáticos mesentéricos se encontraron aumentados hasta tres veces, sin clara delimitación de la corteza y de la médula. Las alteraciones histológicas fueron enteritis y linfadenitis granulomatosa. En tres de los animales se evidenciaron abundantes bacilos ácido alcohol resistentes (BAAR) intracelulares en macrófagos, células gigantes y en el intersticio a la coloración de Ziehl-Neelsen. En otros tejidos evaluados no se encontró inflamación de tipo granulomatoso. Conclusiones. Los criterios diagnósticos empleados, así como el análisis de la información diagnóstica generada en otros estudios, permiten confirmar la presencia, circulación y mantenimiento del Mycobacterium avium subsp. paratuberculosis en el hato con un aparente número elevado de animales infectados.

ABSTRACT

Descreve-se o primeiro caso de paratuberculose em veado pudu-do-sul (Pudu pudu). O animal foi encontrado na cidade de Concepción, centro sul do Chile, em péssimas condições e com sinais claros de diarréia. Internamente apresentava séria atrofia de gordura no coração, lesões histológicas nos pulmões, fígado, baço e rins, e injúrias intestinais. Diferentes amostras foram preparadas com Ziehl-Neelsen, e os linfonodos mesentéricos presentes no íleo foram fortemente positivos para a bactéria resistente ao ácido.

ABSTRACT

Antecedentes: La investigación de la microflora subgingival en pacientes diabéticos tipo 2 con periodontitis ha presentado resultados contradictorios. Objetivo: Determinar la presencia de Porphyromonas gingivalis, Tannerella forshytia, Treponema denticola y Aggregatibacter actinomycetemcomitans, en el biofilm subgingival de pacientes diabéticos tipo 2 y relacionarlo con el grado de control metabólico. Método: Estudio descriptivo transversal, en el cual se analizaron 23 pacientes diabéticos derivados consecutivamente del Policlínico de Especialidades de la Universidad de los Andes. Previo consentimiento informado, se realizó un examen clínico periodontal que incluyó mediciones de profundidad al sondaje, nivel de inserción clínica y sangrado gingival. Fueron clasificados según severidad de periodontitis y control metabólico de la diabetes determinado por un promedio de 3 exámenes de hemoglobina glicosilada. La detección microbiológica se realizó mediante la técnica de reacción en cadena de la polimerasa. Resultados: En el grupo de pacientes estudiados, Treponema denticola y Tannerella forsythia fueron las bacterias más prevalentes (65.2 por ciento), seguida por Porphyromonas gingivalis (17.3 por ciento) y Aggregatibacter actinomycetemcomitans (13 por ciento). Los pacientes con peor control glicémico tuvieron una mayor presencia de Treponema denticola, Tannerella forsythia, Porphyromonas gingivalis y Agreggatibacter actinomycetemcomitans y un aumento en el índice de sangrado al sondaje. Conclusiones: En el grupo de pacientes diabéticos estudiado, las bacterias más prevalentes fueron Treponema denticola y Tannerella forsythia. Los pacientes diabéticos tipo 2 con moderado y mal control glicémico presentaron mayor presencia de los microorganismos estudiados, comparado con los grupos con mejores niveles de control glicémico.


Background: The investigation of subgingival microflora in type 2 diabetic patients with periodontitis presented conflicting results. Aim: To determine the presence of Porphyromonas gingivalis, Tannerella forshytia, Treponema denticola and Aggregatibacter actinomycetemcomitans in subgingival biofilm of patients with diabetes type 2 and to relate it to the degree of metabolic control. Method: A descriptive study, which analyzed 23 diabetic patients consecutively referred from the Internal Medicine Unit of Medicine Faculty at Universidad de los Andes was conducted. After obtaining an informed consent from the patients a clinical examination that included measurements of periodontal pocket depth, clinical attachment level and gingival bleeding was performed. The patients were classified according to the severity of periodontitis and metabolic control of diabetes as determined by an average of 3 of glycosylated haemoglobin tests. Microbial technique was performed by chain reaction of polymerase. Results: In the group of patients examined the most prevalent bacteria were, Treponema denticola and Tannerella forsythia (65.2 percent), followed by Porphyromonas gingivalis (17.3 percent) and Aggregatibacter actinomycetemcomitans (13 percent). Patients with poor glycemic control had a greater presence of Treponema denticola, Tannerella forsythia, Porphyromonas gingivalis and Agreggatibacter actinomycetemcomitans and an increase in the rate of bleeding on probing. Conclusions: In the group of diabetic patients studied, the most prevalent bacteria were Treponema denticola and Tannerella forsythia. Type 2 diabetic patients with moderate and poor glycemic control had a higher presence of these microorganisms, compared to groups with higher levels of glycemic control.

ABSTRACT

Objetivo: El objetivo de este estudio clínico fue evaluar y comparar la eficacia en la reducción de la hipersensibilidad dentinaria de la arginina al 8 por ciento-carbonato de calcio, monofluorfosfato (1.450 ppm) en comparación con un grupo control tratado en base a un barniz de flúor (22.600 ppm) y un dentífrico fluorado (1.450 ppm), 3 veces al día durante un minuto, en pacientes con hipersensibilidad radicular en forma inmediata a la terapia periodontal mecánica (medición basal) y a las 4 semanas respectivamente. Materiales y Método: Estudio clínico aleatorizado de grupos paralelos, con 4 semanas de seguimiento, en el cual se reclutaron 20 pacientes con diagnóstico de periodontitis crónica leve a moderada, en tratamiento periodontal mecánico con presencia de recesiones gingivales a nivel de incisivos, caninos o premolares. A todos ellos, previa firma de consentimiento informado y en forma inmediata a los pulidos radiculares, se les aplicó el test térmico de chorro de aire con la jeringa de aire de la unidad dental a nivel de las recesiones gingivales con hipersensibilidad. La molestia o dolor fue determinado mediante la utilización de una escala visual análoga, realizada en forma inmediata a los pulidos radiculares (medición basal). Los pacientes fueron aleatoriamente asignados a uno de los siguientes grupos: grupo control, se les aplicó barniz de flúor (22.600 ppm) en todas las recesiones gingivales y se les indicó un dentífrico fluorado (1.450 ppm); grupo experimental, a quienes se les aplicó pasta tópica de arginina y carbonato de calcio (8 por ciento) a nivel de las recesiones gingivales, complementado con el uso de un dentífrico cuyo componente activo es la arginina al 8 por ciento-carbonato de calcio. Todos los pacientes fueron evaluados 4 semanas posterior a la aplicación y utilización domestica de los agentes des-sensibilizantes por un único examinador. Resultados: Ambos grupos experimentaron una disminución en la sensibilidad dentinaria, sin...


Aim: The aim of this clinical study was to evaluate and to compare the efficacy in reducing the dentine hypersensitivity of an 8 percent arginine, calcium carbonate, 1.450 ppm sodium monofluorophosphate dentifrice with topical application and twice-daily brushing, with a negative control toothpaste containing calcium carbonate and 1.450 ppm fluoride as MFP, after periodontal treatment (baseline) and four weeks respectively. Methods: A four-week clinical study with 20 subjects with diagnosis of slight to moderate chronic periodontitis under mechanical periodontal treatment and presence of gingival recessions in incisors, canines or premolars, stratified based on baseline tooth sensitivity. Subjects brushed with either a 1.450 ppm fluoride dentifrice or a marketed 8 percent arginine calcium carbonate dentifrice twice daily for approximately one minute. At screening, baseline and weeks four, subjects' tooth sensitivity was determined through both evaporative (Schiff and Visual Analogue Scale [VAS]). The same examiner throughout the study performed subject assessments using each stimulus. Results: Both subject groups exhibited significant reductions from baseline to four weeks in dentine hypersensitivity. However, patients who received 8 percent arginine calcium carbonate therapy, exhibited a greater reduction, with a 60 percent of individuals lacking of pain and with a final median of 0 in comparison with the 5 percent fluoride varnish and fluoride toothpaste group in which a 100 percent of subjects felt some degree of pain, presenting a final medium VAS scale of 2.

ABSTRACT

El arco axilar de Langer o músculo axilopectoral es una variación relativamente rara de la inserción del músculo latísimo del dorso. Se identifica en aproximadamente el 1.7 a 7 por ciento de las disecciones axilares y corresponde a un complejo músculofascial, la parte muscular junto con el tendón del músculo pectoral mayor se inserta dentro del labio lateral del surco intertubercular del húmero, mientras que, la parte fascial está formada por bandas fibrosas que se extienden en la parte profunda del músculo pectoral mayor para insertarse en el proceso coracoide entre la unión de los músculos coracobraquial y pectoral menor. El reconocimiento de esta anomalía es importante para los médicos clínicos, cirujanos y fisioterapeutas, ya que obliga a plantearse el diagnóstico diferencial de masas axilares, historia de obstrucción venosa axilar intermitente, o su aparición inesperada en el transcurso de la disección axilar del linfonodo centinela o linfadenectomías. Se presentan tres casos de arco axilar de Langer diagnosticados en la Unidad de Patología Mamaria del Instituto Autónomo Hospital Universitario de los Andes, Mérida, Venezuela, en el periodo 1999-2006, en el transcurso de 210 disecciones axilares practicadas en pacientes con cáncer de mama para identificación del linfonodo centinela o en linfadenectomías.


The Langer's axillary arch or axillopectoral muscle is a is a relatively rare anatomical variation of latissimus dorsi muscle insertion. Langer's arch is identified in up to 1.7 a 7 percent of axillary explorations, and is a musclefascial complex continuous with the iliacal fibers of the latissimus dorsi. The muscular part, together with the tendon of pectoralis major muscle, inserted into the lateral lip of the intertubercular sulcus of the humerus, whereas the fascial part was formed by a fibrous band that extended deep to the pectoralis major muscle to insert into the coracoid process between the attachments of the coracobrachialis and pectoralis minor muscles. The recognition of this anomalies is important to clinicians, surgeons and physical therapist because It should be considered in the differential diagnosis of axillary masses an unexpected finding during axillary dissection by sentinel lymoh nodes or lymphadenectomy. We report three cases of Langer's axillary arch encountered during sentinel lymph node biopsy or lymphadenectomy en 210 patients with breast cancer, at the patology mammary Unit of the University Los Andes Hospital, in 1999-2006 period.

ABSTRACT

Background: Hamman syndrome or spontaneous pneumomediastinum is uncommon and its clinical manifestations are chest pain, dyspnea and subcutaneous emphysema. Aim: To report a series of patients with spontaneous pneumomediastinum. Material and methods: Medical records of patients with the diagnosis of pneumomediastinum, managed between 2002 and 2007 in a public hospital, were retrieved and reviewed. Results: Eight patients aged between 16 and 41 years (five males) were identified. The most common symptom was chest pain and the most common sign was subcutaneous emphysema. A chest X ray was performed in all and a chest CT scan in seven. AH were managed conservatively with oxygen, analgesia and rest. No patient required surgery and the evolution was favorable. Conclusions: The most common presenting complaint of spontaneous pneumomediastinum is chest pain and its management does not require surgery.

ABSTRACT

Hematopoietic precursors transplantation is a therapeutic alternative for leukemia, some metabolic diseases and some immune deficiency syndromes. In its allogeneic variety leukemia eradication is based in the conditioning prior to transplantation and the allograñ effect against leukemia. Umbilical cord blood is an alternative source of hematopoietic precursors when there are no HLA compatible relatives available. Between 2003 and 2007 we have performed five umbilical cord blood transplant in adult patients in a University hospital. All patients had malignant diseases. Conditioning protocols were ablative in all except in one patient and in all, more than one unit of umbilical cord blood was used. Hematopoietic engraftment was confirmed in all patients and the main complications registered were infectious and associated to immunosuppression.

ABSTRACT

La persistencia del conducto onfalomesentérico ha sido reportada en diversas publicaciones pediátricas ya sea a través de la aparición de un divertículo de Meckel que es la forma más común, o ya sea por la aparición de segmentos con permeabilidad parcial o total el mismo. Se han presentado casos esporádicos donde esta anomalía ha originado episodios de obstrucción intestinal en lactantes y niños, especialmente bajo la forma de unabanda fibrosa remanente. La presentación en el adulto, sin embargo, es extremadamente infrecuente. El caso presentado en este reporte muestra hallazgos compatibles con un conducto onfalomesentérico con permeabilidad parcial, que originó un cuadro de obstrucción intestinal en un adulto joven.


The persistence of the onphalomesenteric duct has been reported in several pediatricpublications either through the appearance of Meckel diverticulum that are commonest, orby the appearance of segments with partial or total permeability of itself. Sporadic caseshave appeared where this anomaly has originated episodes of intestinal obstruction ininfants and children specially under the form of a fibrous band. However, adult presentationis extremely infrecuent. The case presented in this report shows compatible findings witha onphalomesenteric conduit with partial permeability, that I originate an intestinal pictureof obstruction in a young adult.

ABSTRACT

Background: Colorectal cancer relapses or metastasizes in 30 percent of cases. Cytokeratin 20 is present in 95 percent of colorectal tumors and their metastases and could be used as a marker to detect tumor cells. Aim: To assess the usefulness and prognostic value of peripheral blood and bone marrow cytokeratin 20 determinations in patients with colorectal cancer. Material and methods: Blood and bone marrow samples were obtained from 56 patients with colorectal cancer aged 26 to 77 years (31 females) before surgical procedure. They were followed for a mean of 22 months (range 2.9 to 72 months) after surgery. Blood and bone marrow from 45 patients without cancer and 35 healthy subjects were used as negative controls. Messenger RNA expression of cytokeratin 20 was studied by real time and nested polymerase chain reaction. Results: Cytokeratin 20 was detected in 6 percent of controls and 41 percent of patients. There was no relation between cytokeratin 20 expression and age, gender, overall survival, tumor relapse, progression, localization or stage. Conclusions: Cytokeratin 20 determination is not useful as a marker of tumor progression or dissemination in patients with colorectal cancer.

ABSTRACT

A survey was conducted in a meeting sponsored by ALAT (Latin American Association of Thoracic Diseases). Each of the seven editors reported about their journal and answered a questionnaire. The improvement in knowledge divulgation is the main motivation of respiratory societies to edit their own journals. To disseminate medical knowledge and report experiences, are the main motivations of authors to submit papers. The most common deficiency of submitted manuscripts is a bad compliance with journal requirements. An improvement in the relationship between author-editor-reviewer should be the best strategy to enhance the quality of the manuscripts. Suggestions to improve the Latin American journals included to professionalize editorial work, to increase the meticulousness of manuscripts reviewers and to reinforce international norms for editing medical journals. Some major problems reported were a lack of a regular and adequate periodicity in publishing the issues, lack of original papers submitted that mean a "milestone" for the specialty a low percentage of submitted papers rejection and a high and frequent turnover of editors. Although several journals are available in electronic indices, they should be maintained in their printed form. Each journal should have printed its subscription fee, even considering that its subscription is included in the annual society membership fee. The feasibility to generate a multinational Latin American Journal on Respiratory Diseases should be explored.
