Publicación Acceso abierto Análisis retrospectivo del carcinoma cutáneo tipobasocelular y escamocelular en Bogotá-Colombia: Epidemiología, prevención y tratamiento(Universidad Nacional de Colombia, 2009-01-01) Barón Estrada, Óscar Iván; Álvarez Sierra, Julián; Montealegre Gómez, GiovanniAntecedentes. El carcinoma cutáneo no melanoma del tipo basocelular (CBC) y escamocelular (CEC), tiene tasas de incidencia cercanas al 13 por ciento y es el más prevalente en la población blanca. Trae elevada morbilidad para el paciente y altos costos para el sistema de salud, y aunque es la neoplasia maligna mas frecuentemente diagnosticada, en Colombia sólo se tienen estadísticas en instituciones oncológicas, haciendo énfasis principalmente en melanomas. Entre los principales factores de riesgo se encuentra la exposición a los RUVB, tipo de piel, la radiación, el virus del papiloma humano (HPV) y su tratamiento incluye medicación tópica, crioterapia, electrofulguración y cirugía. Objetivo. Analizar algunas características epidemiológicas del cáncer cutáneo (CBC - CEC) en nuestro medio, estableciendo similitudes y diferencias respecto a la literatura actual. Material y métodos. En la clínica San Pedro Claver se revisaron 202 historias clínicas de pacientes con diagnóstico confirmado de CBC O CEC de 2004 a 2006 en un estudio retrospectivo de serie de casos y se analiza-ron las variables más comunes como el tipo de lesión, su ubicación, tamaño, patrón histológico y tratamiento. Resultados. Ingresaron en el estudio 112 pacientes, de los cuales cerca del 60 por ciento eran hombres, con una edad media de 69.5 años. El 90 por ciento de las lesiones se localizaban en cara (mejillas, párpados, nariz). Del 70 porciento de las lesiones que correspondían a CBC el tipo histológico más frecuente fue sólido nodular y del 22 porciento de lesiones que correspondían a CEC, el moderada-mente diferenciado de célula grande fue el más común. Las lesiones tuvieron un tamaño promedio de 2 cm y los procedimientos quirúrgicos más usados fueron resección más injerto (44.1%), seguido de resección más colgajo local(23.5%). El 5 por ciento de los pacientes tenían lesiones previas y uno de cada cuatro tuvo algún tipo de recaída. Conclusiones. En Colombia las estadísticas del carcinoma cutáneo (CBC y CEC) tienen un patrón de comportamiento similar a los reportados en la literatura y el pronóstico de-pende de un adecuado diagnóstico y tratamiento, así como de una intervención oportuna en los factores de riesgo.Publicación Acceso abierto Impact of hypothermia during craniosynostosis repair surgery(Sociedad Colombiana de Anestesiología y Reanimación, 2016-07-01) González-Cárdenas, Víctor Hugo; Vanegas-Martínez, María Victoria; Rojas-Rueda, María Elvira; Burbano-Paredes, Claudia Cecilia; Pulido-Barbosa, Nadya TatianatIntroduction: Hypothermia is recognized as a risk factor for perioperative complications inpaediatric patients. High surgical risk procedures serve as a model of exposure to that riskfactor. In particular, surgical correction of craniosynostosis serves as a model for measuringthe impact of hypothermia.Objective: To assess hypothermia-related morbidity and mortality in paediatric patientstaken to craniosynostosis correction.Methodology: Historical cohort study of patients taken to craniosynostosis correction andexposed to hypothermia.Results: With prior approval of the Ethics Committee of the institution, 54 records wereincluded in the analysis. No statistically significant differences were found betweenhypothermia and its impact in terms of morbidity and mortality (death, major bleeding,massive haemorrhage massive transfusion, disseminated intravascular coagulation, needfor vasopressor support, mechanical ventilation time and length of stay, including admission to the intensive care unit). A clinically significant increase in bleeding (severe and massive) and severe hypothermia was found (28.6% vs. 40% and 14.3% vs. 40%, respectively). Conclusions: No statistical differences were found in terms of morbidity and mortality with severe hypothermia (and moderate/severe hypothermia).Publicación Acceso abierto Placental characteristics of monochorionic diamniotic twin pregnancies in relation to early perinatal outcome(International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), 2011) Rojas, José Luis; Acuña, Edgar Mariano; Molina, Saulo; Franco, Alejandro; Alfonso, Diana; Santana, NellyObjectives: To evaluate placental characteristics in relation to perinatal outcome in pairs of monochorionic diamniotic (MCDA) twins in relation to early perinatal outcome.Methods: Between July 2009 and February 2011, 54 pairs of MCDA twins and 2 triplets were delivered in 3 tertiary care centers. All pregnancies were followed with a weekly fetal surveillance for fetal weight discordance and twin-to-twin transfusion syndrome (TTTS). After birth, placentas were observed and stained to search type and number of vascular anastomoses, type and distance between cord insertions and placental distribution. Birth weights as fetal and neonatal mortality and early morbidity were recorded from clinic charts. Placental characteristics were analized in relation to perinatal outcome. Triplets were analized separately. Results: Anastomoses were detected in all placentas with fetal growth alterations in 44% of the studied pregnancies. Between fetuses with growth disturbances 12 pairs were diagnosed as TTTS, 9 pairs as selective intrauterine growth restriction (IUGR) and 3 pairs as growth discordances without IUGR. Eight fetal deaths were recorded, in 2 pregnancies a single fetal death occurred and in other 3 pregnancies both fetuses died in spite of fetal therapy. Relation between abnormal cord insertions and smaller placental territories were seen in all abnormal growth pregnancies and in 50% of pregnancies without growth disturbances. Between discordant growth pregnancies, only all TTTS cases had unequal shared territories and neonatal weight discordance more than 20%. There were 3 cases of severe early morbidity and 6 babies died during the early neonatal period, most in relation to mayor malformations. Conclusions: Placental characteristics are closely related to perinatal outcome, mainly with the presence of TTTS and fetal growth disturbances. Prenatal identification of these characteristics in this group of pregnancies may change parent counselling as surveillance and intrauterine therapy program.Publicación Acceso abierto Stereotactic frame-based guided brain biopsies: experience in a center in Latin America(Bogotá: Fundación Universitaria de Ciencias de la Salud, 2018-05-30) Ordóñez-Rubiano, Edgar Gerardo; Rodríguez-Vargas, Saney; Ospina-Osorio, Jeisson; Zorro-Guío, Oscar Fernando; Patiño, Javier Gustavo; Sánchez Rueda, MarcelaIntroduction: Stereotactic guided biopsies are chosen for deep-located lesions, as well as for those in eloquent areas, when the risk outweighs the benefit of an open procedure, or when open surgery has no advantage over the suspected histology. Objective: This study aims to describe retrospectively the diagnostic yield and the morbidity and mortality related to a series of stereotactic-guided biopsies in a 6-year period in a single center in Latin America. Materials and methods: 62 medical records of patients who underwent stereotactic-guided brain biopsies were reviewed. The clinical features, the morbidity and mortality associated to the procedures were acquired. Results: The complication rate was 2.7% and the diagnostic yield reached 87%. The most frequent location of the target was frontal and the most frequent diagnosis was glioblastoma. Conclusions: The complication rate and the diagnostic yield in this series were similar to the observed in different series performed with frame-based stereotactic procedures or performed with neuronavigation in the literature.
