Quistes de colédoco, una causa inusual de ictericia en pediatría: presentación de serie de casos / Bile duct cysts; an unusual cause of jaundice in paediatrics: presentation of a case series

Introducción Los quistes de la vía biliar o quistes de colédoco (QC) son una patología rara en nuestro medio. La etiología es desconocida, siendo la hipótesis más aceptada las anomalías en la unión biliopancreática. Objetivo Analizar los datos clínicos, diagnóstico y tratamiento de una serie de pacientes diagnosticados de QC y realizar una actualización sobre el tema. Metodo Se revisaron retrospectivamente los diagnósticos de QC en 20 años en un hospital terciario. Casos clínicos Se identificaron 4 casos, con predominio del sexo femenino. Rango de edad 16 meses a 4 años. Los signos y síntomas fueron ictericia y coluria (100%), vómitos (75%), dolor abdominal y acolia (50%). Ninguno tuvo masa palpable. La ecografía abdominal orientó el diagnóstico que se confirmó con colangio-resonancia magnética (colangio-RM). Se clasificaron como QC tipo I tres de los casos y uno como tipo IVa. El tratamiento fue quirúrgico, ningún paciente presentó complicaciones hasta la fecha. Conclusiones Los quistes de las vías biliares son de baja prevalencia. El tratamiento de elección es quirúrgico, requiriendo seguimiento estrecho, dado el riesgo de colangiocarcinoma.

Introduction Cysts of the bile duct or choledochal cysts are rare diseases in our area. The aetiology is unknown, with the most accepted hypothesis being a pancreatobiliary maljunction anomaly. Objective To analyse the clinical data, diagnosis and treatment of a number of patients with choledochal cyst, as well as presenting an update on this condition. Method A retrospective descriptive study was performed on paediatric patients diagnosed with choledochal cyst in the last 20 years in a tertiary hospital. Case reports A total of 4 choledochal cyst cases in childhood, predominantly female, are pre- sented. The most frequent reason for consultation was vomiting, and presenting with jaundice and choluria in all cases. Patients with choledochal cyst were classified as type I in 3 cases, and one case of type IVa. In all cases surgical treatment was performed; any patient had complications to date. Conclusions Cysts of the bile ducts have a low prevalence. The treatment of choice is surgical, requiring close monitoring due to the risk of cholangiocarcinoma.

Guías clínicas para la detección, prevención, diagnóstico y tratamiento de hipertensión arterial sistémica en México (2008) / Clinical guidelines for detection, prevention, diagnosis and treatment of systemic arterial hypertension in Mexico (2008)

The multidisciplinary Institutional Committee of experts in Systemic Arterial Hypertension from the National Institute of Cardiology [quot ]Ignacio Chávez[quot ] presents its update (2008) of [quot ]Guidelines and Recommendations[quot ] for the early detection, control, treatment and prevention of Hypertension. The boarding tries to be simple and realistic for all that physicians whom have to face the hypertensive population in their clinical practice. The information is based in the most recent scientific evidence. These guides are principally directed to hypertensive population of emergent countries like Mexico. It is emphasized preventive health measures, the importance of the no pharmacological actions, such as good nutrition, exercise and changes in life style, (which ideally it must begin from very early ages). [quot ]We suggest that the changes in the style of life must be vigorous, continuous and systematized, with a real reinforcing by part of all the organisms related to the health education for all population (federal and private social organisms). It is the most important way to confront and prevent this pandemic of chronic diseases[quot ]. In this new edition the authors amplifies the information and importance on the matter. The preventive cardiology must contribute in multidisciplinary entailment. Based mainly on national data and the international scientific publications, we developed our own system of classification and risk stratification for the carrying people with hypertension, Called HTM (Arterial Hypertension in Mexico) index. Its principal of purpose this index is to keep in mind that the current approach of hypertension must be always multidisciplinary. The institutional committee of experts reviewed with rigorous methodology under the principles of the evidence-based medicine, both, national and international medical literature, with the purpose of adapting the concepts and guidelines for a better control and treatment of hypertension in Mexico. This work group recognizes that hypertension is not an isolated disease; therefore its approach must be in the context of the prevalence and interaction with other cardiovascular risk factors such as obesity, diabetes, dislipidemia and smoking among others. The urgent necessity is emphasized to approach in a concatenated form the diverse cardiovascular risk factors, since independently of which they share common pathophysiological mechanisms, its suitable identification and cont
