ABSTRACT
La diarrea crónica secretora es una entidad frecuente. Las causas son múltiples, por lo que llegar al diagnóstico definitivo puede resultar demorado con las complicaciones que esto ocasiona en el estado general del paciente. Se presenta el caso de un adulto mayor que cursa con diarrea crónica asociada a hipokalemia leve y acidosis metabolica hiperclorémica secundaria a un VIPoma a nivel de retroperitoneo, la cual es una localización inusual de este tipo de tumores, que en este caso fue diagnosticado mediante una biopsia guiada por tomografía...
Chronic secretory diarrhea is a frequent entity. Causes are multiple, that is why reaching final diagnosis can result in delay with complications that this causes in the general condition of the patient. We present the case of one older adult with chronic diarrhea, mild hypokalemia and metabolic hyperchloremic acidosis secondary to a VIPoma in retroperitoneum which is an unusual location of this type of tumor that was diagnosed by biopsy guided by tomography...

Los tumores neuroendocrinos (TNE) presentan dificultad en el diagnóstico por sus síntomas inespecíficos y el manejo es un reto. Se presenta el caso de un varón de 78 años de edad, con dolor crónico en hemiabdomen superior. Ingresó a emergencia con obstrucción intestinal y síntomas de síndrome carcinoide (SC). En cirugía se resecó tumor ileal con resultado anatomopatológico de tumor neuroendocrino, cromogranina positivo, índice proliferativo ki 67 de 2 a 3 por ciento. El paciente continuó con síntomas de SC, altos niveles de 5-HIA, metástasis hepáticas en RMN. Se inició octreotide con adecuada respuesta clínica. La experiencia con el presente caso indica estar alerta con los síntomas de TNE funcionantes, debido al aumento en su incidencia. Es de utilidad solicitar marcadores inmunohistoquimicos. La identificación de un TNE con índice de mitosis y proliferación bajo indica buen pronóstico...
The neuroendocrine tumor (NET) is of difficult diagnosis due to nonspecific symptoms; management is also a challenge. We present the case of a 78 year-old male who suffered of chronic upper abdominal pain and was admitted to emergency with intestinal obstruction and symptoms of carcinoid syndrome (CS). At surgery an ileal tumor was resected with pathology report of NET positive for chromogranin A and ki 67 proliferative index of 2-3 per cent. The patient continued with CS symptoms and presented high levels of 5-HIAA and liver metastases by MRI. Octreotide was started with good outcome. Experience with this case indicates to be alert at symptoms of functioning NET, due to an increase in its incidence. It is useful to request immunohistochemical markers. Identification of NET with low grade mitosis and proliferation signal good prognosis...

OBJECTIVE: To assess the prevalence of high blood pressure (PHBP) and its association with age, sex, socioeconomic status (SES), and body mass index (BMI = kg/m2). MATERIAL AND METHODS: A cross-sectional survey was carried out in 1996, in a random sample of 356 adults aged 20 and older, residents of Bucaramanga, Colombia. Weight, height, and blood pressure readings were obtained, plus data on age and gender. Robust linear and log-binomial regression was used to estimate the independent effect of different risk factors on systolic (SBP) and diastolic (DBP) blood pressure and HBP. RESULTS: Mean SBP and DBP were significantly higher in men (122.5 and 88.1 mmHg) than in women (117.2 and 75.4 mmHg). The adjusted SBP increased with age, more in men than in women; DBP did not change with age. For each unit increase in BMI, SBP and DBP increased 0.76 and 0.69 mmHg, respectively. SBP was 6.8 and DBP was 9.8 mmHg higher in low-SES than in high-SES subjects. The adjusted PHBP increased with age and was higher in subjects > or = 50 years than in those 20-30 years old. Sex had no significant effect on PHBP (p = 0.795). For each unit increase in BMI the PHBP increased 3, and low-SES subjects had a PHBP 1.84 times higher than high-SES subjects. CONCLUSIONS: A high PHBP was found. There is a great potential for prevention by weight control. Further studies are needed to confirm the increasing PHBP in low-SES subjects and to identify its causes.
