RESUMEN
We report the clinical case of a man who survived a massive attack of Africanized bees (>2000 bee stings). The man experienced anaphylactic shock and multisystem organ failure (neurologic, hepatic, renal, and hematologic failure). He was treated with administration of dopamine hydrochloride, antihistaminic agents, corticosteroids, fluid and electrolyte replenishment, peritoneal dialysis, and plasmapheresis. No sequelae have been observed during follow-up.

Gastric carcinoid tumors arise from enterochromaffin-like (ECL) cells, these tumors represent 2-41% of all neuroendocrine tumors and 0.3% of malignant gastric neoplasias, being more common in men than in women, and commonly affecting people over 60 years old. These tumors arise from accelerated proliferation of the ECL cells as a consequence of the hypersecretion of gastrin, situation that can be present in atrophic gastritis and the Zollinger-Ellison syndrome. We report the case of a 51 year old hispanic female who presented with a 3 month history of abdominal pain, meteorism and constipation; she was treated with ranitidine and metoclopramide without clinical improvement, thus she underwent upper gastrointestinal endoscopy which showed an atrophic gastritis and gastric polyps. Histopathologic examination revealed a neuroendocrine gastric tumor which was positive to serotonine and gastrin stainings. Hormonal screening showed normal serum levels of LH, FSH, estradiol, ACTH, progesterone, calcitonin and cortisol. The serum level of gastrin was elevated with 500 pg/mL. Gammagraphic scanning with octreotide was negative for metastasis.

UNLABELLED: The scope of this work is to analyze the usefulness and indications of preoperative evaluation. PATIENTS AND METHODS: 791 consecutive patients candidate for surgical treatment, were studied prospectively under the next inclusion criteria: 40 years old or less than 40 years old. Blood count cell, glucose, urea, creatinine, sodium, potassium, prothrombin time, partial thromboplastin time, platelets count, liver function tests, chest x-ray and electrocardiograph made before entry. In the the post liver, lung, bleeding, infectious or metabolic complications was done, while visiting the patients every day until discharge. Relative risk (RR) was calculated for every variable, analyzing differences with X2 and Fisher's Test. Those variables with statistical significance value were analyzed with logistic regression. Only 751 patients were studied, there were 335 male (44%) and 416 female (56%), with mean age of 63.9 years. Metabolic disorders (16.9%) and postoperative infections (7.0%) were the more frequent complications. Hemorrhage during of after surgery occurred in 2.2% of the patients. There were seventeen deaths (2.2%) related directly with surgery, with systemic illness or with postoperative complications. Selection of auxiliary tests for preoperative evaluation must be agree with clinical evaluation. The major objective of clinical evaluation is to estimate risk factors for surgery.
