ABSTRACT
Pulmonary hypertension is a clinical condition with a low prevalence, but carries high morbidity and mortality. Important advances in the understanding of this disease and in its therapy have occurred. A particular scenario is pulmonary hypertension in patients undergoing non-cardiac as well as cardiac surgery. The aim of this review is to present information that may allow diagnostic and therapeutic approaches of this clinical condition in patients undergoing surgery.

El síndrome de úlcera solitaria del recto es una entidad poco frecuente, caracterizada por una alteración de la dinámica defecatoria. Se presenta habitualmente entre la tercera y cuarta década, con igual distribución en ambos sexos, la forma de presentación incluye el antecedente de constipación crónica, rectorragia, pujo y tenesmo. Dentro del diagnóstico diferencial destaca el tumor rectal. El estudio de esta patología incluye rectoscopia, defecografía e histología, dando este último el diagnóstico definitivo. El tratamiento es médico-quirúrgico reservándose este último para los casos más severos. Se presentan 5 casos tratados en el Servicio de Cirugía del Hospital San Juan de Dios entre los años 1989 y 1999, todos confirmados con diagnóstico histopatológico, realizándose un estudio descriptivo en cuanto a su presentación clínica, su estudio y su tratamiento

Entre las neoplasias cutáneas, el carcinoma de células escamosas ocupa el segundo lugar en frecuencia de los tumores malignos. Se ha observado un aumento en su prevalencia e incidencia siendo los principales factores de riesgo, el grado, frecuencia y tiempo de exposición solar. Afecta las zonas de la piel expuestas al sol. Quirúrgicamente en la Unidad de Cirugía de Cabeza y Cuello del Hospital San Juan de Dios entre enero de 1991 y diciembre de 1999.

One hundred eleven seropositive donors, detected between 1994 and 1996, were studied. Serological reactions were confirmed with ELISA and indirect immunofluorescence reactions. Those confirmed as positive were subjected to a clinical-epidemiological questionnaire, physical examination, EKG and barium enema or swallow according to symptoms. Results: Seventy individuals were confirmed as positive for Chagas disease. Most of them lived at least once in an endemic zone for Chagas positive for Chagas disease. Most of them lived at least once in an endemic zone for Chagas disease or in a sun-dried clay brick house. Forty percent of individuals knew reduviid bugs and 14 pecent had been bitten by these insects. Twenty six percent of these subjects had an abnormal EKG (6 percent with bradicardia). No digestive diseases attributable to Chagas disease were detected. Conclusions: The high prevalence of problems attributable to Chagas disease among seropositive blood donors underscores the need of an epidermiological follow up of these individuals
