OBJETIVE : To evaluate the efficacy of pancreatic allograft transplantation (TAP ) in dogs with diabetes mellitus ( DME ) induced by alloxan . METHODS : 63 mongrel dogs were used , of which 33 for the very best experimental conditions , the other 30 were divided into 3 groups of 10 each : a) controls, were only produced DME b ) receptors with DME, the who underwent TAP and c) pancreas donors . RESULTS : The glycemic control was complete in 50% of recipients and partial in 30% , giving an overall efficiency of TAP relative to control 80 %. The survival time was 19.9 + TAP post - 6,2 hours. Pathologic examination showed signs of hyperacute rejection , Major complications were gastrointestinal bleeding , aspiration pneumonia , necrotizing pancreatitis with generalized peritonitis , hypoglycemia and dogs not awakened from anesthesia. CONCLUSIONS : The TAP was effective in controlling blood g...

Neuroendocrine tumors generally originate in the digestive tract or pancreas, developing liver metastases throughout their evolution. The presence of a primary neuroendocrine tumor of the liver is still controversial and there are very few cases. We present a case of a primary neuroendocrine tumor of the liver confirmed by anatomo-pathological study and images. The patient underwent two major liver resections, lastly preserving only segment IV.

Los tumores neuroendocrinos generalmente se originan en el tracto digestivo o páncreas, desarrollando metástasis hepática a lo largo de su evolución. La presencia de un tumor neuroendocrino primario de hígado es motivo de controversia y de muy escasa casuística. Presentamos el caso de un tumor neuroendocrino primario de hígado confirmado por estudio anatomo-patológico e imágenes. La paciente fue sometida a dos resecciones hepáticas mayores, preservando sólo el segmento IV.

OBJECTIVE: To determine the incidence of Plasmodium falciparum malaria in Querecotillo, an area with a course of increasing prevalence rates for this disease. MATERIAL AND METHODS: Information consigned at the 1997 Book of Record and Following of Malaria Patients, was analyzed. RESULTS: Ages ranged predominantly between 15 and 44 years (69,6% of cases). Incidence rate was 14,2%; and the villages of Peña, Puente, Victoria and Querecotillo had the highest prevalence rates. Population in able-to-work ages was the most affected, and the peak incidence was during May, June and July. CONCLUSIONS: Querecotillo is a high risk area for Plasmodium falciparum malaria, and there are economic, social, cultural and weather factors which exerts influence on disease statistics.

BACKGROUND: Resistance rates of Plasmodium falciparum in Querecotillo, Sullana, reported by the cohort study for the first semester of 1998, were greater than 50%. OBJECTIVES: To determine the types of Plasmodium falciparum antimicrobial resistance in this district. METHODS: A descriptive, retrospective study in which all malaria cases attended since January 01 to June 30, 1998, was evaluated. RESULTS: Male was the most affected gender (57,4%), and 66,5% of patients were between 15 to 44 years-old. 24,5% of cases was chloroquine-sensible, whereas 75,4% was resistant. Type specific resistance rates found were R1: 29,9%; R2: 13,2% and R3: 32%. CONCLUSION: Resistance rate of Plasmodium falciparum to chloroquine in Querecotillo, was as high as 75%.
