Introduction Insulinomas are pancreatic endocrine neoplasms with a low incidence between 1-4 cases per million per year. Case description: A female 49 years-old with neurological and psychiatric symptoms were treated for two years as a psychiatric patient. Presented a glucose value, which reflects hypoglycemia. The patient was operated with resolution of symptoms. Conclusion: Assess all patients with psychiatric symptoms and perform a complete medical history and laboratory findings, being the most opportune glucose Source:  Sociedad de Neurología, Psiquiatría y Neurocirugía de Chile (SONEPSYN URL:  http://hdl.handle.net/10757/311275

Dear editor: We read with greatinterestthe article Bullying among schoolchildren: differences between victims and aggressors, recently published in Gaceta Sanitaria.1 Motivated by this study, we would like to share information about the characteristics of victims and aggressors of bullying in Peru after an extensive literature search about this underexplored topic in our country and attempt some comparisons versus Spain as well as some concluding remarks and recomendations. Bullying in Peru, as very likely in Spain, is a hidden and yet latent phenomenon. Moreover, it varies across regions in our country and profiles might be different than what is found in Spain. In a study conducted in an urban Lima school in 2007, victims usually had fewer friends, spent more time alone at recess and exhibited decreased self-confidence than non-victims.2 Similarly, another study conducted in in 2009 found that adolescents with any physical defects are more prone to being bullied, being excluded by ag...

A bibliometric study was carried out to describe the scientific production on cancer written by peruvians and published in international health journals, as well as to assess the scientific collaboration networks. It included articles on cancer written in Peru between the years 2000 and 2011 and published in health journals indexed in SCOPUS or Science Citation Index Expanded. In the 358 articles identified, an increase in the production was seen, from 4 articles in 2000 to 57 in 2011.The most studied types were cervical cancer (77 publications); breast cancer (53), and gastric cancer (37). The National Institute of Neoplastic Diseases (INEN) was the most productive institution (121 articles) and had the highest number of collaborations (180 different institutions). 52 clinical trials were identified, 29 of which had at least one author from INEN. We can conclude that, cancer research is increasing in Peru, the INEN being the most productive institution, with an important parti...

Background: Learning research skills should be a goal during undergraduate training of physicians. Aim: To identify Latin American medical students’ appraisal on research skills university training. Material and Methods: A self-administered survey about experience in research, self-assessment of research skills, quality of training in the area received at the university and that importance of publishing as undergraduate students, was answered by 208 medical students aged 23 ± 3 years (54% male), attending a medical students congress. Results: Seventy percent of respondents pertained to medical students’ scientific societies and 34% had published in a scientific journal. Fifty two percent considered as good or very good the training level received at their universities on information retrieval and 45% considered good the training in research methodology. Thirty two percent considered as poor or none the training received in scientific writing and 37% in the publishing proce...

The proportion of resistance found to the evaluated antimicrobials was ampicillin (62.6%),  cotrimoxazole (48,6%), tetracycline (43,0%) and chloramphenicol (15,8%). We emphasize the high resistance levels  found for quinolones: 32% for nalidixic acid (NAL) and 12% for ciprofloxacin (CIP). These high levels of quinoloneresistance  in non-pathogenic strains isolated from children in this age group highlight the extensive use and the impact of  the intake of this kind of antimicrobials in the community, showing the potential risk of the loss of their utility in the area.

Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflat...
