ABSTRACT

El cáncer primitivo del duodeno (CPD) es raro, y en nuestro Hospital representa el 0,008% de las biopsias. En el período 1945-90, descartando los tumores de la ampolla de Vater, hallamos catorce casos: ocho adenocarcinomas (ADC), cinco linfomas y un histiocitoma maligno. Los ADC generalmente son periampulares; los otros dos tumores son infraampulares. La sintomatología más frecuente fue dolor, obstrucción duodenal y compromiso del estado general, de comienzo insidioso. El dolor abdominal predominó en los pacientes con ADC y la diarrea, en los enfermos con linfomas. El diagnóstico, por lo general es tardío, cuando el tumor está avanzado. El diagnóstico etiológico se hizo principalmente por biopsia endoscópica (12 casos), y quirúrgica, sólo en 2 casos. La radiología con medio de contraste y el TAC abdominal son técnicas complementarias y permiten conocer la extensión de la lesión. El tratamiento de los adenocarcinomas es quirúrgico: pancreatoduodenectomía en las formas localizadas; cirugía derivativa paliativa en las formas avanzadas, que son las más frecuentes. En los linfomas, la quimioterapia es el tratamiento de elección, además de cirugía resectiva para los casos localizados. En el seguimiento hallamos sólo un paciente vivo, que corresponde a una enferma con linfoma no Hodgkin, sometida a cirugía resectiva y quimioterapia, 52 meses antes. La mayor sobrevida alcanzada en nuestra serie, fue de 13 años, y corresponde a una paciente con ADC sometida a pancreatoduodenectomía radical. La sobrevida promedio de los pacientes con linfomas que han fallecido, es superior a la de aquellos con adenocarcinomas (39 meses vs. 27 meses)

ABSTRACT

Blood pressure, weight and cardiovascular risk factors were evaluated in 73 adults of Easter island (mean age 49 ñ 12.9 (SD) years) in January 1989 and 1990. Their mean blood pressure (BP) was 129 ñ 24/81 ñ 14, significantly higher by 7/5 mmHg than in 1979 (p < 0.05). Of the population studied 30% of subjects were hypertensives. Both systolic 9S) and diastolic blood pressure (DBP) correlated with age (r=0.40, p < 0.005 and r = 24,p < 0.05 respectively). In males body mass index correlated strongly with SBP and DBP (r = 0.55, p < 0.005 and r = 0.52,p < 0.01). Forty eight % of subjects were obese, 60% smoked (14 cigarettes/day), 38% drank alcohol and 70% lead sedentary lifes; their level of stress was considered average. In 23 normotensives or undiagnosed hypertensives 24 hour urine was collected for sodium, potassium, creatinine and kallikrein; mean urinary sodium exretion was 121 ñ 30 mmol/day; potassium excretion 59 ñ 29 mmol/day, creatinine excretion 1383 mg/day and kallikrein excretion 682 ñ 355 m/day; of these, only urinary sodium was significantly lower than values determined in a group of 29 continental volunteers. Eleven natives that had never left the island had similatr BP and risk factors than a sex and age paired sample, who has spent 10.9 ñ 7.8 years in the continent. The present study demostrates that Easter Island natives have increased their mean BP in 10 years, elevated their BP with age and have lost the protection previously associated to staying in the island. In this sample the prevalence of hypertension (30%) was high. We postulate that the 2 main factors determining the BP elevation are a sodiumintake greater than 100 mmol/day and a high prevalence of obesity, which plays a stronger hypertensogenic role in males. It is highly probable that the contamination is due to returning migrants and to the massive entry of tourists
