  • Postnatal nephro-urology findings of patients with prenatal diagnosis of

    • Abstract: No es clara la repercusión clínica de la hidronefrosis. Este estudio busca determinar las características de las imágenes diagnósticas de los pacientes con hidronefrosis prenatal y determinar si el valor del diámetro anteroposterior de la pelvis renal puede identificar la presencia de malformaciones urológicas posnatales y la necesidad de cirugía. Materiales y métodos: estudio transversal en el que se revisaron las historias clínicas de todos los pacientes con edades entre 0 y 5 años de edad, con diagnóstico prenatal de hidronefrosis, quienes consultaron a un hospital de cuarto nivel de complejidad en la ciudad de Medellín - Colombia. Cada unidad renal se evaluó en forma independiente. Resultados: en total se estudiaron 135 unidades renales de 97 pacientes. No se encontró hidronefrosis posnatal en el 17,8 %. Al seguimiento, el 85 % de los pacientes con estenosis pieloureteral y 90 % de los pacientes con valvas de uretra posterior fueron clasificados prenatalmente como hidronefrosis moderada a grave. Por el contrario, el 41,4 % de los riñones con diagnóstico de reflujo vesico-ureteral fueron clasificados como hidronefrosis leve, 34,5 % moderada y 24,1 % grave. El 56,3 % de los riñones necesitaron algún tipo de cirugía. El 26 % de las hidronefrosis clasificadas como leves necesitaron algún procedimiento quirúrgico. Un diámetro anteroposterior de la pelvis renal de 10,5 mm tuvo una sensibilidad de 67 % y una especificidad de 71,2 % para la detección de malformaciones nefro-urológicas. Conclusión: la hidronefrosis prenatal, independiente de su grado, puede ser indicativa de malformaciones del tracto genitourinario. Se recomienda un seguimiento estricto en los pacientes con hidronefrosis, incluso en los casos leves, para así detectar tempranamente la presencia o no de malformaciones nefro-urológicas que requieran algún tipo de intervención.Currently, we do know the clinical repercussions of prenatal hydronephrosis. This study aims to assess the imaging features of hydronephrosis patients and to determine whether the renal pelvis value in the prenatal ultrasound correlates with the presence of urologic malformations and the need for surgery. Materials and methods: Cross sectional study. We evaluated the medical records of all patients almost 5 years old with prenatal hydronephrosis who had consulted during 2006-2010. Results: we analyzed 97 patients, for a total of 135 kidneys. 17.8 % had not hydronephosis; 85.1 % of the patients with pyeloureteral junction stenosis and 90 % of those with posterior urethral valves had been prenatally classified as having mild to severe hydronephrosis. Conversely, 41.4 % of kidneys with vesicouretral reflux were classified as having mild hydronephrosis, 34.5 % moderate and 24.14 % severe. Furthermore, 56.3 % of the evaluated kidneys needed some type of surgery. It is also worth mentioning that it was necessary to perform surgical procedures on 26 % of the kidneys with mild hydronephrosis. Finally, the analysis of the ROC curve made it possible to find that, when the pelvis has an anteroposterior diameter of 10.5 mm, the sensitivity for the detection of nephro-urologic malformations is 67 % and the specificity 71.2 %. Conclusion: prenatal hydronephrosis, regardless of its degree, may be an indication of malformations in the urinary tract. We recommend performing strict follow-ups on the patients to determine the presence of nephro-urologic malformations requiring some kind of intervention.
  • Description of clinic, anatomopathologic and treatment characteristics of
           pacients with breast cancer a senology unit in Medellin, Colombia; 2006-

    • Abstract: Introducción: la investigación del cáncer de mama se ha centrado en el estudio de las características biológicas e inmuno-histoquímicas del tumor, como elementos pronósticos de la sobrevida libre de enfermedad, la sobrevida global y como elementos predictivos de respuesta a las terapias. Metodología: estudio descriptivo y retrospectivo de características biológicas y anatomopatológicas de pacientes con cáncer de mama atendidas desde enero de 2006 a junio de 2013 en Medellín. Resultados: descripción de 1 480 casos de cáncer de mama, el promedio de edad fue de 54 años. El carcinoma in situ se diagnosticó en el 10 % de los casos y el carcinoma invasivo en el 83 %. Este último se presentó como forma no específica en el 80 %, como lobulillar infiltrante en el 7 % y como tipo especial en el 3 %. La positividad para los receptores de estrógeno fue de 73 %, receptores de progesterona en 64 % y para el receptor HER2 neu fue de 15 %. El carcinoma infiltrante de mama se diagnosticó en el 48 % en estadíos localmente avanzados y el 3 % en estadíos metastásicos. El 11 % de los pacientes recibió manejo quirúrgico conservador de la mama más biopsia de ganglio centinela, 7 % recibió manejo quirúrgico conservador con vaciamiento axilar. En el 58 % de los casos se realizó mastectomía simple más biopsia de ganglio centinela; de éstas, al 5 % se les realizó reconstrucción inmediata. En el 15 % de las pacientes se les practicó mastectomía radical modificada. El 65 % requirió adyuvancia con quimioterapia. Conclusiones: este trabajo permite aproximarse al conocimiento más detallado de los aspectos biológicos de los casos de cáncer de mama de una unidad de mastología de Colombia y pone en evidencia la necesidad de implementación de estrategias clínicas e imaginológicas para diagnosticar en mayor proporción el cáncer de mama en estadíos tempranos en las mujeres de nuestra población.Introduction: The research in breast cancer has been focused in the study of the biological and immunohistochemically characteristics, as elements for prognostic factors of disease free survival and overall survival and as predictive elements in response to therapies. This study describes the clinical and pathologic features of patients treated for breast cancer in a breast unit in Medellin during the years 2006-2013. Methods: A descriptive and retrospective trial was performed evaluating variables from medical records of breast cancer patients who attended a breast cancer unit in Medellín, Colombia between January 2006 and June 2013. Results: There were 1,480 cases of breast cancer patients, with mean age of 54 years old. In situ carcinoma was diagnosed in 10 %, and invasive carcinoma was diagnosed in 83%; 80% of the cases was carcinoma non-specified type, invasive lobular carcinoma 7% and special types 3%. Estrogen receptor was positive in 73%, progesterone receptor was positive in 64% and HER 2 neu was positive in 15%. Early stage breast cancer was observed in 32%, locally advanced in 48% and metastatic stage in 3% of the cases. In 7% of the cases did not found information about this. 11% of the patients had conservative breast surgery (BCS) plus sentinel lymph node biopsy (SNB) and 7 % had BCS with axillary lymph node dissection (ALND). 58% had simple mastectomy plus SNB and of these patients, 5% had immediate reconstruction. 15% had modified radical mastectomy (MRM) and 7% of these patients had immediate reconstruction. In 65% adyuvant chemotherapy was performed and in 57% had adyuvant radiotherapy. Adyuvant endocrine therapy was received by 63% specially with Tamoxifen. Conclusions: The results of this study allows more detailed approach to the biological aspects of cases of breast unit of Colombia awareness and highlights the necessity for implementation of clinical and imaging strategies to diagnose greater proportion of breast cancer in early stages in our women population.
  • Preliminary results of the safety and efficacy with a hybrid treatment of
           insufficiency of the great saphenous vein

    • Abstract: Introducción: en el tratamiento de la incompetencia de la safena mayor la radiofrecuencia y el láser se han asociado a neuralgia y otras complicaciones, debido a extensión de la lesión térmica. La escleroterapia con espuma abre un nuevo horizonte en el tratamiento de venas más complejas, alcanzando sin dolor las dilataciones epifasciales. Existe preocupación acerca de si esta técnica en el manejo de lesión troncular, eleva la posibilidad de una reapertura de la unión safeno-femoral. Nuestro grupo desarrolló un abordaje híbrido con termo-ablación con radiofrecuencia y esclero-espuma. Métodos: se incluyeron 87 pacientes con clasificación CEAP de C2-C4 con incompetencia y dilatación de la safena mayor documentado por ecografía dúplex. El manejo híbrido se realizó mediante acceso percutáneo ecoasistido de la safena mayor con el catéter corto de radiofrecuencia VNUS ClosureFAST, 2 cm distal a la unión safeno-femoral y bajo anestesia infiltrativa. Se llevó a cabo la termo-ablación de la unión safeno-femoral y safena mayor subyacente. Previo a la extracción del catéter se inyectaron 8 cc de espuma de cloruro de lapirio al 1 % en todos los casos (tasa de preparación con técnica de Tessari de 4:1). El seguimiento se llevó a cabo durante seis meses e incluyó dúplex de la pierna tratada para establecer la oclusión de la safena mayor y unión safeno-femoral. Resultados: 83 pacientes completaron el seguimiento. A 78 pacientes se les detectó oclusión de la safena mayor y unión safeno-femoral al sexto mes postoperatorio y cinco requirieron una segunda dosis de espuma en el segmento recanalizado. Siete pacientes reportaron dolor en el área inguinal en el postoperatorio inmediato. No se presentaron complicaciones mayores. Conclusiones: este es un reporte preliminar de un procedimiento híbrido que involucra el uso de energía térmica para ocluir completamente la unión safeno-femoral y tratar en el mismo tiempo quirúrgico la safena mayor y dilataciones epifasciales asociadas, sin la necesidad de utilizar energía térmica en el tronco safeno o el uso de flebectomía complementaria. La tasa de oclusión parece prometedora, pero es necesario un mayor seguimiento para poder establecer su verdadero alcance.ABSTRACT Background: Treating the insufficiency of the Greater saphenous vein (GSV), using radiofrequency (RF) and LASER ablation have been associated to neuralgia and other complications due to the extension of the thermal injury. Foam sclerotherapy opened a new trend in the treatment of larger veins, reaching superficial varicosities, but the treatment of the GSV, raises the possibility of a quick reopening of the saphenofemoral junction (SFJ). Our group developed an approach that merges the benefits of thermal injury and foam sclerotherapy. Methods: 87 patients classified as C2-C4 (CEAP classification), 73 female, mean age: 58.4 with incompetence and dilatation of GSV where included in this study. Our Hybrid procedure was performed using ultrasound guided percutaneous access of GSV with a new short RF catheter (VNUS Closure FAST) distal to the SFJ under local anaesthesia. Thermal occlusion of the saphenofemoral junction (SFJ) and GSV subjacent segment was achieved. Just before retrieving the device, we injected 8cc of 1 % Lapidium Chloride foam using physiological gas. Duplex ultrasound was carried out to assess GSV and SFJ occlusion; follow-up was at completed 6 months. Results: 83 patients completed the follow-up period. 78 patients had their GSV and SFJ occluded at 6 months demonstrated by duplex ultrasound and 5 required a second dose of foam sclerotherapy. Four patients were lost during follow-up due to change of address. Seven patients reported pain in the groin area immediately after the procedure. There were no major complications. Conclusions: This is a preliminary report of a hybrid procedure that involves use of thermal energy to occlude the SFJ and treat at the same time the GSV and associated varicosities, without the need for further thermal usage of the venous trunk or the use of phlebectomy. This hybrid procedure combines the best of this two techniques, minimizing their disadvantages and potentiating their advantages. The occlusion rate seems promising but further studies should evaluate its effectiveness in time.
  • Bioavalability study of Metformin 850 mg immediate-release tablets

    • Abstract: Se desarrolló un estudio de biodisponibilidad de metformina 850 mg tabletas recubiertas de liberación inmediata elaboradas por Laboratorios Coaspharma S.A., en 12 voluntarios sanos de ambos sexos, con edades entre 18 y 26 años. Para llevarlo a cabo se validó previamente un método bioanalítico para la determinación de metformina en plasma humano por cromatografía líquida de alta resolución con detector ultravioleta (HPLC-UV), el cual resultó ser selectivo, específico, lineal, exacto y preciso, por lo tanto adecuado para el análisis de las muestras. Estas fueron recolectadas periódicamente en un lapso desde 0 a 24 horas, luego de la administración por vía oral de una única dosis de metformina 850 mg. Posteriormente se determinaron los parámetros farmacocinéticos promedio de los 12 participantes, obteniendo: área bajo la curva, desde tiempo cero hasta el último tiempo de muestreo t (AUC0--->t) 6856,89 ± 2073,8 ng.h/ml, área bajo la curva desde tiempo cero hasta tiempo infinito (AUC0--->∞) 7083,74 ± 2131,52 ng.h/ml, concentración máxima (Cmaxmax) 1299,02 ± 291,90 ng/ml, tiempo máximo (t) 2,33 ± 0,47 h, tiempo de vida media (t1/2) 2,50 ± 0,84 h y constante aparente de eliminación (Ke) de 0,31 ± 0,12 h-1. Los resultados fueron similares en todos los participantes y no se produjeron reacciones adversas.A bioavailability study was conducted in 12 healthy volunteers of both genders, aged between 18 and 26. Previous to the study, a bioanalytical method for determination of metformin in human plasma by high performance liquid chromatography with ultraviolet detector (HPLCUV) was validated, and proved to be selective, specific, linear, accurate precise, and therefore, suitable for analysis in plasma. Samples were collected from 0 to 24 hours after the oral administration of a single dose of metformin 850 mg immediate-release coated tablets, produced by Coaspharma S.A. Laboratories. Then, average pharmacokinetic parameters of the twelve volunteers were determined: area under the curve from time zero to last sampling time t (AUC0--->t) 6856.89 ± 2073.8 ng.h/mL, area under the curve from time zero to infinite time (AUC0--->∞) 7083.74 ± 2131.52 ng.h/ml, maximum concentration (Cmax) 1299.02 ± 291.90 ng/mL, maximum time (t max) 2.33 ± 0.47 h, half-life (t1/2) 2.50 ± 0.84 h and apparent elimination constant (Ke) of 0.31 ± 0.12 h-1. These results are similar between the volunteers and no adverse effect was observed. Also, the results are in agree with those reported in literature.
  • Prevalência dos sintomas da endometriose . : Revisão Sistemática

    • Abstract: bjetivos: estabelecer qual a prevalência dos sintomas nas mulheres com endometriose, levando-se em consideração os dados epidemiológicos e o comprometimento dos sistemas por ela acometidos. Fonte de dados: A pesquisa foi realizada nas bases de dados: Medline (Ovid Web); Scopus e PubMed. Métodos de revisão: Foram incluídos estudos publicados a partir de 2009. Os estudos foram avaliados por dois revisores independentes que avaliaram o título, e o resumo e posteriormente cruzaram os dados, as discrepâncias foram analisadas por um terceiro revisor. Após este processo os textos completos foram analisados e os dados relevantes à pesquisa extraídos. Resultados: Os estudos revelam que os sintomas referentes ao sistema reprodutor são os mais característicos no quadro de endometriose. Mulheres de raça branca, com nível superior completo e idade média de 34 anos são as mais acometidas. E tempo de demora do diagnóstico é em torno de 5 anos. Conclusões: Os principais sintomas prevalentes encontrados nesta revisão foram a dismenorréia, a dor pélvica crônica e a dispareunia, mas sintomas secundários como a depressão também tem se tornado significativos. Eles aparecem, sobretudo nas mulheres caucasianas e em idade reprodutiva, acentuando-se perto do período menstrual, onde o estrógeno está presente em maiores quantidades, e aliviando com a gravidez e com a menopausa.Objetivos: establecer cuál es la prevalencia de los síntomas en las mujeres con endometriosis, teniendo en cuenta la información epidemiológica y el compromiso de los sistemas que se afectan. Fuente de datos: la búsqueda se realizó en las bases de datos: Medline (Web Ovid); Scopus y PubMed. Métodos: se incluyeron estudios publicados desde 2009. Los estudios fueron evaluados por dos revisores independientes que evaluaron el título y el resumen y luego cruzaron los datos; las discrepancias fueron analizadas por un tercer revisor. Después de este proceso se analizaron los textos completos y extrajeron los datos relevantes para la investigación. Resultados: los síntomas relacionados con el sistema reproductivo son los más característicos en la endometriosis. Las más afectadas son las mujeres de raza blanca con títulos universitarios y edad promedio de 34 años. El retraso al momento del diagnóstico es de alrededor de cinco años. Conclusiones: los principales síntomas predominantes que se encuentrraron en esta revisión fueron dismenorrea, dolor pélvico crónico y dispareunia, pero los síntomas secundarios como la depresión también son importantes. Aparecen principalmente en las mujeres caucásicas en edad reproductiva, cerca de la menstruación, cuando el estrógeno está presente en cantidades más grandes y se alivian con el embarazo y la menopausia.Objectives: to establish what its the prevalence of symptoms in women with endometriosis, taking into account the epidemiological information and the commitment of the systems suffer from it. Data Source: The survey was conducted in the databases: Medline (Ovid Web); Scopus and PubMed. Review methods: We included studies published since 2009. The studies were assessed by two independent reviewers who assessed the title and the summary and then crossed the data, discrepancies were analyzed by a third reviewer. After this process the full texts were analyzed and extracted data relevant to research. Results: The studies reveal that the symptoms related to the reproductive system are the most characteristic in endometriosis frame. Whites women with college degrees and average age of 34 years are the most affected. And it delays the diagnosis time is around 5 years. Conclusions: The main prevalent symptoms found in this review were dysmenorrhea, chronic pelvic pain and dyspareunia, but secondary symptoms such as depression has also become significant. They appear mainly in Caucasian women of reproductive age, emphasizing close to the menstrual period, where the estrogen is present in larger quantities, and relieving with pregnancy and menopause.
  • Monoclonal B-cell lymphocytosis: a review of general

    • Abstract: Introducción: la linfocitosis monoclonal de células B es una condición que se caracteriza por tener menos de 5x10(9)/L células B clonales en la sangre periférica, en ausencia de signos clínicos o síntomas de un trastorno linfoproliferativo crónico de células B. Métodos: se realizó una búsqueda de artículos publicados en bases de datos multidisciplinarias y específicas de las áreas de la salud como Pubmed, Ovid, Science Direct, SciELO, Scopus y Embase; se emplearon términos relacionados con el tema como Monoclonal B lymphocytosis, Monoclonal B cell lymphocytosis and chronic lymphocytic leukemia, Monoclonal B-cell lymphocytosis, chronic lymphocytic leukemia, con su contraparte en español; además se incluyeron algunos capítulos de libros. Se seleccionaron los artículos que cumplían con criterios de calidad metodológica y de contenido. Resultados: diferentes estudios basados en grandes series hospitalarias de linfocitosis monoclonal de células B, han puesto de manifiesto un riesgo más elevado de los sujetos con la entidad de progresar a leucemia linfocítica crónica. Algunos investigadores afirman que la mayoría de las personas con linfocitosis monoclonal de células B tipo leucemia linfocítica crónica no desarrollarán enfermedad progresiva en un período de cinco años aproximadamente, el 75 % estará vivo con un recuento de linfocitos estable y entre el 1 y 4 % por año desarrollará progresivamente una enfermedad que requiere tratamiento. Conclusiones: existe gran variedad en la prevalencia de linfocitosis monoclonal de células B, dependiente en gran medida de las características de la población examinada y de los métodos de detección utilizados para su identificación. Los factores de riesgo que determinan el paso de linfocitosis monoclonal de células B a leucemia linfocítica crónica están aún por determinarse; sin embargo, diversos estudios han reportado que la edad, el sexo, los antecedentes familiares de leucemia linfocítica crónica, la presencia de algunos polimorfismos de nucleótido simple y marcadores como ZAP 70, CD38 y CD49d, podrían estar relacionados con el riesgo de desarrollar la enfermedad. Sin embargo, hasta ahora el factor mejor definido de progresión es el recuento absoluto de células B.Introduction: monoclonal lymphocytosis of B cells is a condition characterized as having less than 5x10(9)/L clonal B cells in the peripheral blood, in the absence of clinical signs or symptoms of a chronic B cell lymphoproliferative disorder Methods: a search of articles published in multidisciplinary databases and specific areas of health, such as PubMed , Ovid , Science Direct, SciELO, Scopus and Embase data was performed; also some book chapters were included. Terms related with the topic were used like Monoclonal B lymphocytosis, Monoclonal B cell lymphocytosis, and chronic lymphocytic leukemia, Monoclonal B-cell lymphocytosis, chronic lymphocytic leukemia. Articles that met criteria for methodological quality and content were selected. Results: different studies based on large hospital series of MBL, have manifested a higher risk of subjects with MBL progressing to B-CLL. Some researchers claim that most people with MBL type LLC will not develop progressive disease over a period of about 5 years, 75 % will be alive with a stable count of lymphocytes and between 1 % and 4 % per year will gradually develop a disease requiring treatment. Conclusions: there is great variation in the prevalence of MBL, dependent largely on the characteristics of the study population and the detection methods used for identification. Methods using increasingly sensitive detection has led to the identification of increasingly smaller MBL clones. Risk factors that determine the passage of monoclonal B-cell lymphocytosis to chronic lymphocytic leukemia are yet to be determined, however, several studies have reported that the age, sex, family history of CLL, the presence of some single nucleotide polymorphisms and markers such as ZAP 70, CD38 and CD49d, could be related to the risk of developing the disease. But so far the best defined progression factor is the absolute B cell count.
  • Computational fluid dynamics in intracranial aneurysm

    • Abstract: Los aneurismas cerebrales son lesiones arteriales caracterizadas por el debilitamiento y la dilatación de un segmento del vaso sanguíneo. Representan una gran amenaza para la vida del paciente debido al riesgo de ruptura, trombo-embolias o compresión del tejido adyacente. Los aneurismas cerebrales rotos son la causa más común de la hemorragia subaracnoidea y puede causar una significativa morbilidad y mortalidad. Con el fin de entender el comportamiento hemodinámico de los aneurismas cerebrales se han desarrollado estudios computacionales que simulan las condiciones y propiedades de dichas lesiones en modelos virtuales similares a la realidad; la mayoría de ellos se realizan en un sistema experimental conocido como dinámica de fluido computacional. Este artículo presenta una revisión del estado de la técnica aplicada a hemodinámica de flujo en aneurismas y pretende recopilar los avances más importantes del método que servirán en un futuro, para el desarrollo de una herramienta de apoyo al diagnóstico y tratamiento de estas dolencias.Intracranial aneurysms are lesions of the arterial wall characterized by weakening and dilation of an arterial segment. These lesions are a major threat to the patient’s life because of the risk of rupture, thrombo-emboli, or compression of adjacent tissue. The rupture of an intracranial aneurysm causes subarachnoid hemorrhage associated with high mortality and morbidity rates. In order to understand the intracranial aneurysm hemodynamics, it has been developed computational studies, which simulate the boundary conditions and properties of these lesions in virtual models (models similar to reality), most of them are made in a computational fluid dynamic model (CFD). This study reviews the state of arts of the CFD technique applied to the aneurysm flow hemodynamics that claims to collect the most important progress of the method that will be useful in the tool’s developments that will become a rely on a diagnosis and treatment tool.
  • Neuropsychological profile : Parkinson’s Disease/Lewy
           Body Dementia

    • Abstract: La demencia por cuerpos de Lewy y la enfermedad de Parkinson son dos síndromes comunes con signos y síntomas similares que hacen difícil establecer un diagnóstico exacto, especialmente en las etapas intermedias y tardías de cada cuadro clínico en particular. La enfermedad de Parkinson es una entidad lenta y progresiva que se caracteriza por temblor de reposo, rigidez, bradiscinesias e inestabilidad postural. En ella, los síntomas neurocognitivos y conductuales como la depresión, la disfunción ejecutiva y atencional, la baja fluidez verbal y las fallas de memoria inmediata pueden aparecer desde las etapas iniciales de la enfermedad e ir empeorando y progresando, cuando aparece un cuadro demencial secundario a la enfermedad. Por su parte, la enfermedad por cuerpos de Lewy se considera un cuadro neurodegenerativo que se ha asociado a la presencia de cuerpos de Lewy a nivel cortical y subcortical y se caracteriza por signos extrapiramidales, fluctuaciones cognitivas y alucinaciones visuales. En ella los síntomas neurocognitivos y conductuales son "fluctuantes" en lo relacionado con el nivel de consciencia, las funciones ejecutivas y atencionales, la memoria episódica y la presencia/ausencia de alucinaciones visuales. Las diferencias sutiles de ambas enfermedades exigen una revisión exhaustiva en la evolución de los síntomas. La evaluación neuropsicológica como herramienta diagnóstica se limita en tanto que no reemplaza, los estudios de imagen y otros hallazgos neuropatológicos para el diagnóstico definitivo, pero permite objetivar el perfil neuropsicológico más propio de cada enfermedad, en particular para un diagnóstico más preciso.Lewy body dementia and Parkinson´s disease are two frequent syndromes that share similar signs and symptoms, especially during intermediate and chronic phases of each particular clinical picture, making an accurate diagnosis very difficult to establish. Parkinson’s disease is a slow and progressive disorder characterized by tremor at rest, stiffness, bradykinesia and postural imbalance. Many neurocognitive and behavioral symptoms such as depression, executive and attentional dysfunction, lower verbal fluency and immediate memory failures can appear in early stages of the disease, increasing and progressing as a secondary dementia develops. Lewy body dementia is considered a neurodegenerative disorder associated to Lewy bodies in both cortical and subcortical regions. It is characterized by the presence of extrapyramidal features, cognitive fluctuation and visual hallucinations. Neurocognitive and behavioral symptoms fluctuate concerning level of consciousness, executive and attentional function, episodic memory and the presence/absence of visual hallucinations. Subtle differences in both disorders demand an exhaustive review of symptom´s evolution. Neuropsychological evaluation as a diagnostic tool is limited. It cannot replace neuroimaging studies and other neuropathological findings for a definite diagnosis, but determines each neuropsychological profile in particular for a more accurate diagnosis.
  • The adipocyte in the laboratory : history, perspectives and
           report of experience

    • Abstract: Introducción: el tejido adiposo humano está compuesto por diferentes tipos celulares, y ha sido objeto de múltiples estudios en los últimos años debido a su acción en diversas funciones. Métodos: se realizó una búsqueda bilbiográfica en PubMed, Scielo, Science Direct and Google Scholars y se reporta la experiencia de los autores. Resultados: los primeros modelos de estudio fueron con tejido de roedores, y permitieron la comprensión del metabolismo de carbohidratos y ácidos grasos y facilitaron el estudio de la biología del adipocito, junto a estudios histológicos y el aislamiento de adipocitos maduros. Posteriormente se realizaron estudios con células precursoras (preadipocitos) que propiciaron el aislamiento de la línea celular 3T3-1L murina. En Latinoamérica, se han realizado diversos estudios con líneas celulares y con células madre mesenquimales precursoras de adipocitos para estudiar el efecto de hormonas y otras sustancias y para genotipificación. En Colombia se han realizado estudios con adipocitos 3T3-L1 para determinar los efectos de medicamentos y sustancias en estas células. En el laboratorio de Fisiología Celular de la Universidad Tecnológica de Pereira el proceso de obtención de muestras ha evidenciado dificultades por tratarse de tejido humano, pero el protocolo de aislamiento y cultivo pudo ser estandarizado a lo largo de seis años de experimentación; se aislaron preadipocitos y adipocitos maduros que permitieron estudiar los efectos de hormonas, realizar caracterización electrofisiológica y estudiar la fisiología del calcio. Conclusiones: este es un campo de investigación muy relevante debido a la implicación de este tipo celular en funciones metabólicas sistémicas y su relación con patologías de alta prevalencia como la obesidad y el síndrome metabólico.Introduction: The human adipose tissue is composed of different cell types. It has been subject of several studies in the past years due to its role on diverse functions. Methods: A search in the PubMed, Scielo, Science direct and Google Scholars databases was performed and the authors experience was reported. Results: The first model used was rodent fat, which allowed a better comprehension on carbohydrate and fatty acid metabolism and enhanced research in adipocyte cell biology in addition with histological studies and mature adipocyte isolation. Afterwards, learning about precursor cell (pre-adipocytes) promoted the isolation of murine 3T3-L1 cell line. In Latin America research has been conducted using cell lines and adipocyte precursor mesenchymal stem cells to describe effects of hormones and perform DNA sequencing. In Colombia, studies in 3T3-L1 cell line aimed to stablish the effects of different compounds on these cells. In the Cell Physiology Laboratory of the Universidad Tecnológica de Pereira, sample collection process has shown difficulties because the source was human tissue; nevertheless isolation and cell culture protocols were standardized throughout the last six years of experimentation. Pre-adipocytes and mature adipocytes were isolated to study the effects of hormones, perform electrophysiological characterization and study calcium physiology. Conclusions: This is a relevant research field since these cells have important systemic metabolic functions and they have a clear relationship with high-prevalence pathologies such as obesity and the metabolic syndrome.
  • Integrative Medicine; effects of acupuncture and its clinical application
           in allopathic medicine

    • Abstract: La acupuntura ha sido utilizada hace más de 3 000 mil años en la medicina tradicional china. En la actualidad, la Organización Mundial de la Salud (OMS) reconoce esta práctica para el manejo integral del dolor y de otras condiciones clínicas. Su aplicación para el manejo del dolor crónico y refractario a los tratamientos convencionales es considerada como una terapia útil, segura, efectiva y placentera no sólo para el manejo del dolor, sino también para disminuir los efectos adversos producidos por los tratamientos oncológicos. En los últimos 15 años, el National Institutes of Health junto con el National Center for Complementary and Integrative Health han realizado múltiples estudios científicos, logrando identificar muchos de los mecanismos neurológicos por los cuales la acupuntura logra su efecto terapéutico. En la actualidad la medicina integrativa hace parte de la oferta académica de muchas universidades, hospitales e instituciones dedicadas a la educación médica, con el fin de ampliar el manejo integral del paciente, abarcando su enfermedad desde el contexto integral del ser y permitiendo que la evidencia determine su aplicación clínica. En Medicina no se puede rechazar un tratamiento por ignorancia y desconocimiento, por esto es necesario que bajo la evidencia científica se logren validar los tratamientos, permitiendo conocer cuáles son las opciones integrales, seguras y efectivas para que los pacientes mejorar su calidad de vida.Acupuncture has been practiced in traditional Chinese medicine for more than 3000 years; currently, the World Health Organization (WHO) acknowledges this practice for the integrative pain management and other clinical conditions. Its application for the chronic and refractory pain management with conventional treatments, allows it to be a useful, secure, effective and pleasant therapy not only for the pain management, but also to decrease the adverse effects of oncologic treatments. In the last 15 years the National Institutes of Health altogether with the National Center for Complementary and Alternative Medicine allowed conducting multiple scientific studies, to enable the identification of the neurologic mechanisms through which acupuncture achieves its therapeutic effects. Nowadays integrative medicine is part of the academic offer of many universities, hospitals and institutions dedicated to the medical education worldwide, with the aim of optimizing the integrative management of the patient, addressing the disease in the holistic context of the being and allowing evidence to determine the clinical application of this type of treatments. In medicine treatments cannot be rejected due to ignorance or lack of information, therefore it’s necessary to be able to validate treatments based on scientific evidence, to allow us to find which are the integrative, secure and effective options so that patients can improve their quality of life.
  • 3 cases of cocaine - levamisole syndrome in Medellín

    • Abstract: El levamisol es un antihelmíntico de uso veterinario que ha sido utilizado como aditivo a la cocaína con el objetivo de aumentar los efectos psicotrópicos de dicha sustancia. Esta mezcla produce reacciones como agranulocitosis, vasculitis cutánea y modulación del sistema inmune. Solamente el reconocimiento, tratamiento adecuado y la suspensión del consumo de esta sustancia lleva a la desaparición de las lesiones y sugiere fuertemente el diagnóstico. Presentamos tres casos de síndrome cocaína/levamisol en Medellín y una revisión de la literatura con algunos conceptos de esta enfermedad.Levamisole, an anthelmintic veterinary product is known to be used as an additive to cocaine that enhances the psychotropic effects of this substance. This mixture leads to reactions such as agranulocytosis, skin vasculitis and modulation of the immune system. Only the proper recognition, treatment of this entity and discontinuation of this substance consumption, leads to the disappearance of lesions; strongly suggesting the diagnosis. We present three cases of cocaine/levamisole syndrome in the city of Medellin and a review of the literature with some concepts related to this pathology.
  • Atrial myxoma : more than a beningn neoplasm

    • Abstract: RESUMEN Los tumores cardíacos son parte del diagnóstico diferencial en el estudio de las masas intracardíacas, junto con vegetaciones, trombos, calcificaciones valvulares, entre otros. Su localización, tamaño y movilidad pueden dar lugar a importantes implicaciones funcionales y anatómicas que determinan la presentación clínica. Describimos el caso de una mujer de 51 años de edad, quien se presentó con cuadro sugestivo de un síndrome coronario agudo, pero gracias a los hallazgos ecocardiográficos se le diagnosticó un tromboembolismo pulmonar originado por un mixoma en la aurícula derecha con posterior verificación histopatológica..Cardiac tumors are part of the differential diagnosis in the study of intra-cardiac masses along with vegetations, thrombi, valvular calcifications among others. Their localization, size and mobility can lead to major anatomical and functional implications determining the clinical presentation. We describe the case of a 51 year-old female, who presented with complains suggestive of an acute coronary syndrome, in which an echocardiographic showed it a pulmonary embolism caused by a right atrial myxoma with histopathological verification was made.
