Use of information sources by recently graduated physicians of Lima

 In order to determine the use of information sources by recently graduated physicians of Lima, Peru in 2011, a survey was conducted among graduated physicians at seven universities. They were asked about the use of search engines in the health area during their year of medical internship [last year of medical school]. Regular use was defined as the source being used once a week or daily. For 490 respondents, regularly used information sources were SciELO, accessed by 173 (36.4%); PubMed 165 (34.4%); HINARI 117 (25.5%); UpToDate 98 (22.3%); Cochrane Library 94 (20.6%); LILACS 91 (19.8%); a hospital institutional library 70 (15.0%); LIPECS 39 (8.7%); and Peru BVS 42 (9.3%). Only a minority regularly accessed information sources related to health. It is necessary to improve capacity in the efficient use of various resources of scientific information in a continuous way and that reaches students and health professionals.

First subregional meeting of health sciences students’ scientific journal editors, Arequipa, Peru, 2014

Sr. Editor:
El progreso de las ciencias y del conocimiento depende cada vez más del trabajo cooperativo entre distintos grupos de investigación y es clave para mejorar la producción científica1 . En la búsqueda de esa cooperación, las revistas científicas estudiantiles no son la excepción, pues desde hace años se realizan reuniones internacionales para editores estudiantiles con el fin de crear redes de apoyo y mejora del proceso editorial2 . Desde 1998 se realiza anualmente un encuentro de editores de revistas estudiantiles, organizado por la Federación Latinoamericana de Sociedades Científicas de Estudiantes de Medicina (FELSOCEM)2 . Sin embargo, infortunadamente, muchos encuentros no han podido llevarse a cabo apropiadamente, como ocurrió en los años 2010, 2011, 2012 y 2014. Por ello y como una forma alternativa de fortalecer el trabajo de esos encuentros internacionales, este año la Sociedad Científica Médico Estudiantil Peruana (SOCIMEP), entidad nacional que agrupa a las sociedades científicas de estudiantes de medicina en Perú, creó el Primer Encuentro Subregional de Editores de Revistas Científicas de Estudiantes de Medicina (dirigido a editores de Perú, Chile y Bolivia), que se realizó en el marco del XXVIII Congreso Científico Nacional, en la ciudad de Arequipa, Perú.

Case Report: Possible Vertical Transmission of Bartonella bacilliformis in Peru

A 22-day-old male was admitted with a 2-day history of irritability, dyspnea, jaundice, fever, and gastrointestinal bleeding. A thin blood smear was performed, which showed the presence of intraerythrocyte bacteria identified as Bartonella bacilliformis, and subsequently, the child was diagnosed with Carrion’s disease. The diagnosis was confirmed by specific polymerase chain reaction. The child was born in a non-endemic B. bacilliformis area and had not traveled to such an area before hospitalization. However, the mother was from an endemic B. bacilliformis area, and posterior physical examination showed the presence of a wart compatible with B. bacilliformis in semi-immune subjects. These data support vertical transmission of B. bacilliformis.

Identification of human papillomavirus as a preventive strategy for cervical cancer in asymptomatic women in the Peruvian Andes

Objective: To detect the most prevalent human papillomavirus (HPV) genotypes samples of asymptomatic Peruvian women by analyzing the correlation betwe ienn c Pearvpiacnailc somlaeoaur (PAP)-stained cervical tests and PCR-sequencing.

Antiviral activity of maca (Lepidium meyenii) against human influenza virus

Objective: To investigate antiviral activity of maca to reduce viral load in kidney (MDCK) cells infected with influenza type A and B viruses (Flu-A and MFalud-inB-, Dreasrpbeyc ctiavneilny)e. Methods: Maca were extracted with methanol (1:2, v/v).

Results: The methanol extract of maca showed low cytotoxicity and inhibited influenza-induced cytopathic effect significantly, while viral load was reduced via inhibition of viral growth in MDCK infected cells. Maca contains potent inhibitors of Flu-A and Flu-B with a selectivity index [cytotoxic concentration 50%/IC50] of 157.4 and 110.5, respectively. Conclusions: In vitro assays demonstrated that maca has antiviral activity not only against Flu-A (like most antiviral agents) but also Flu-B viruses, providing remarkable therapeutic benefits.
