Evolución posquirúrgica de la hipertensión arterial pulmonar asociada a conducto arterioso permeable a una altitud de 2680 metros sobre el nivel del mar / Postoperative evolution of pulmonary arterial hypertension associated with patent ductus arteriosus at an altitude of 2680 meters above sea level

Introducción: El conducto arterioso permeable puede provocar hipertensión arterial pulmonar; éste ocupa el primer lugar de las cardiopatías congénitas quirúrgicas en la ciudad de Toluca, México. Métodos: En el periodo comprendido entre enero del 2006 y diciembre del 2011 se operaron 51 pacientes con conducto arterioso permeable: 34 (66.7%) del sexo femenino. Se estudia la reversibilidad de la presión arterial pulmonar y de la dilatación de cavidades izquierdas posterior al cierre quirúrgico del conducto arterioso permeable y se describen las complicaciones posquirúrgicas en la población de la ciudad de Toluca, localizada a una altitud de 2680 metros sobre el nivel del mar (msnm). Resultados: La reversibilidad de la presión pulmonar ocurrió en el 88% de los casos. También se observó una disminución de los diámetros de las cavidades izquierdas, manifestado por una relación de aurícula izquierda/anillo aórtico prequirúrgica de 2.0±0.41 y posquirúrgica de 1.36±0.25 (p<0.001). El cierre exitoso del conducto arterioso permeable inmediato fue del 94.1% y mediato del 98.0%. Se presentaron complicaciones posquirúrgicas en el 13.8% de los pacientes, todas fueron menores, siendo las principales: infección y hematoma de la herida quirúrgica (5.9%), neumotórax (3.9%), neumonía (2.0%) y derrame pleural (2.0%). Conclusiones: La hipertensión arterial pulmonar secundaria a conducto arterioso permeable es reversible en la mayoría de los casos después del cierre quirúrgico, incluso en habitantes de localidades por arriba de los 2500 msnm.

Introduction: Patent ductus arteriosus in Toluca can cause pulmonary hypertension and ranks first surgery of congenital heart disease in Toluca, Mexico. Methods: In the period between January 2006 and December 51 patients with patent ductus arteriosus went to surgery: 34 (66.7%) were female. We study the reversibility of pulmonary arterial pressure and the left cavities dilatation after surgical closure of the ductus arteriosus and postoperative complications are described in a population of Toluca, located at an altitude of 2680 meters over the sea. Results: The reversibility of pulmonary pressure ocurred in 88% of cases. We also observed a decrease in the diameters of the left chambers manifested by a ratio of left atrium/aortic annulus before surgery of 2.0 ± 0.41 SD and after surgery of 1.36 ± 0.25 SD, (p<0.001). The successful closure of the ductus arteriosus was 94.1% immediately and mediate 98.0%. Postoperative complications ocurred in 13.8%, being the main infection and surgical wound hematoma (5.9%), pneumothorax (3.9%), pneumonia (2.0%) and pleural efusion (2.0%). Conclusions: Pulmonary arterial hypertension secundary to patent ductus arteriosus is reversible in the mayority of cases after surgical closure, including residents of village above 2500 meters over the sea.

[Multiple cardiac rhabdomyoma associated to intrauterine death]. / Rabdomioma cardiaco múltiple asociado a muerte intrauterina.

Rhabdomyoma is the most common cardiac tumor detected during fetal life and childhood; nevertheless its incidence is very low. This is a histologically benign tumor, but in some cases may cause hemodynamic repercussion with date of low cardiac output, arrhythmias and exceptionally intrauterine death as occurred in our case, which was detected by obstetric ultrasound and fetal echocardiogram and corroborated by histological study.

[Clinical evolution and cardiovascular complications in children with Kawasaki disease]. / Enfermedad de Kawasaki: evolución y complicaciones cardiovasculares en niños.

OBJECTIVE: to describe the type of presentation, the clinical manifestations, the response to treatment and the coronary artery abnormalities in eleven cases of children with Kawasaki disease. METHODS: Eleven patients who fulfill diagnostic criteria for Kawasaki disease were studied in a six years period. RESULTS: the mean age was 26 months, 80 % of patients were less than 5 years old, the male-female ratio was 1:1.2; no differences between typic and atypic presentation were found. The most frequent clinical manifestation (80 %) was non-exudative conjunctive injection, followed by polymorphic exanthema and mucosal involvement in the mouth. Nine of 11 patients (82 %) received treatment with intravenous immunoglobulin during the first 10 days of fever; seven of these patients showed coronary artery ectasia; they showed in the echocardiogram a complete resolution in the first year of follow-up. Two patients (18 %) without intravenous immunoglobulin developed coronary aneurysms. CONCLUSIONS: the Kawasaki disease is the main cause of acquired cardiopathy in the pediatric age in our hospital, an early diagnosis and treatment within 10 days of the beginning of the fever allowed a reduction of coronary artery alterations in these patients.

[Intrapericardial teratoma in the neonatal stage: diagnosis and evolution]. / Teratoma intrapericárdico en etapa neonatal: diagnóstico y evolución.

Intrapericardial teratomas in fetal and neonatal stages are rare. They invade the mediastinum compromising the venous return to the heart and leading to hydrops. We report a case of a neonate with fetal hydrops who required ventilatory support at birth and urgent surgical treatment due to severe respiratory failure. During surgery, a multicyst mass was resected in the anterior mediastinum, corresponding to an immature teratoma.

[Ten year experience with ocular lymphomas and ocular adnexae lymphomas]. / Experiencia de 10 años en linfomas oculares y de anexos oculares.

BACKGROUND: Ocular lymphomas and ocular adnexae lymphomas (OL and OAL) constitute 7-8% of all extranodal lymphomas. OBJECTIVE: Describe the clinical, morphologic and immunophenotypic characteristics of OAL seen in our hospital. MATERIAL AND METHODS: Retrospective analysis of patient records with OL and OAL between July 1994 and July 2005. The following data was analyzed: Clinical presentation, therapy, treatment response, overall survival and disease free survival. RESULTS: Ten patients with OL and OAL were identified. Of these, 8 were women and 2 men. Median age was 50. Eight of 10 patients achieved complete remission, 6 of the 6 presenting MALT Lymphoma. Two patients with stage IV had refractory disease. CONCLUSIONS: In our series 0.02% of lymphomas were OL and OAL of a total 498 LNH. MALT lymphomas appear at a more advanced age, sixty percent of the cases were MALT lymphomas and were diagnosed during their early stages. Patients were followed during 21 months, global survival was 100%, free illness survival had a mean of 868 days and a survival median of 442 days.

Experiencia de 10 años en linfomas oculares y de anexos oculares / Ten year experience with ocular lymphomas and ocular adnexae lymphomas

Antecedentes. Los linfomas oculares (LO) y de los anexos oculares (LAO) tienen una incidencia de 7- 8% de todos los tumores extraganglionares. Objetivo. Describir las características clínicas, morfológicas e inmunofenotípicas de los LO y LAO atendidos en el Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán. Material y métodos. Se revisaron los expedientes de los pacientes con diagnóstico de LO y LAO de julio de 1994 a julio del 2005. Se analizaron los siguientes datos: presentación clínica, tratamiento, respuesta al tratamiento, supervivencia global, y supervivencia libre de enfermedad (SVLE). Resultados. Se analizaron 10 pacientes, 8 mujeres y 2 hombres. La media de edad fue de 50 años. La remisión completa (RC) se presentó en 8 de 10 pacientes y en los 6 pacientes con linfoma de tejido linfoide asociado a mucosas (MALT). Se encontraron dos con enfermedad refractaria, los cuales estaban en estadio IV. Conclusiones. En este estudio los LO y LAO correspondieron a 0.02% de todos los linfomas no Hodgkin (LNH) estudiados (498 casos). Los linfomas tipo MALT se presentan a edad más avanzada, se encontraron en estadios más tempranos y en todos hubo RC, con una SVLE promedio de 868 días y una media de supervivencia de 442 días.
