Introducción: El abuso de fármacos anticolinérgicos es un problema que ocasionalmente se ha reportado en laliteratura médica aunque al parecer su frecuencia puede ser mayor a lo considerado usualmente; sobre todo enpacientes con esquizofrenia, donde se indica anticolinérgicos para contrarrestar los síntomas extrapiramidalessecundarios al uso de antipsicóticos, es donde se detectan la mayoría de casos. Método: reportamos cuatro casos depacientes con esquizofrenia que abusaban de anticolinérgicos y revisamos la literatura pertinente. Resultados: Eluso excesivo de anticolinérgicos por pacientes con esquizofrenia ha sido atribuido a su intento de controlar síntomas depresivos o negativos o la disforia inducida por antipsicóticos sin embargo no hay usualmente correlación entre el uso de antipsicóticos y el abuso de anticolinérgicos; por tanto, es menester considerar el poten...

Las automutilaciones que son objeto de atención psiquiátrica suelen ser atribuibles a enfermedades mentales gravesy acarrean alteraciones anatómicas, funcionales y estéticas importantes: las más reportadas en la literatura sonaquellas más severas (como las enucleaciones oculares y las autocastraciones), seguramente por lo llamativo desu presentación, pero existen otras automutilaciones que también pueden ser objeto de atención clínica. A partirde dos casos infrecuentes: automutilación de la mama en una mujer y de los pabellones auriculares de un varón,con diagnóstico de esquizofrenia ambos, revisamos la bibliografía pertinente y llamamos la atención sobre estosepisodios, en los que la distorsión de la imagen y esquema corporal asomaron como factores relacionados al actoautolesivo, a diferencia de los factores de riesgo más comúnmente señalados en la literatura.

This survey aimed to determine the insect pests associated with Andean lupin (Lupinus mutabilis Sweet) and its parasitoids, under Peruvian central coast conditions. Sampling was made every seven days with the following methods: linear meter evaluations, plant organ evaluations, pitfall traps, and beating trays. Infested plant organs were taken to the laboratory for adult insect recovery (phytophagous or parasitoids). Pitfall traps and beating tray samples were also processed and stored. During the survey, 14,051 individuals belonging to 11 orders and 91 families were recorded. Insects that infested Andean lupin were Melanagromyza lini Spencer (stem borer), Liriomyza huidobrensis (Blanchard) (leafminer), Crocidosema aporema (Walsingham) (budborer), Grammopsoides tenuicornis (Casey) (stem borer) and Frankliniella occidentalis (Pergande) (bud and flower thrips). Diglyphus websteri (Crawford...

This survey aimed to determine the pollinating insects of the flowers of the cherimoya crop (Annona cherimola Mill.) located at the Program of Research and Social Projection in Fruit Trees (PIPS-FRUTALES) at the Universidad Nacional Agraria La Molina. Fifteen trees were selected randomly, and evaluations were performed from 31 October to 15 November 2018. Three replicates were performed, each replicate was formed by a set of five trees and were evaluated in three different weeks. Each tree was evaluated in four quadrants, according to the location of the flowers (external or internal) and the floral phases of the crop (female or male). The collection of the insects from the cherimoya flowers was performed using an aspirator, then the insect morphotypes were determined and classified according to order, family, genus and/or species through the use of taxonomic dichotomous keys and the sup...

We reviewed 113 Clinical Records from the Archive of the Dos de Mayo Hospital since 1976 to 1983, about the mediastinum pathology.  The present retrospective study has as purpose to find the incidence of the mediastinal diseases in our hospital and the findings will be showh in tables and sometimes in grafphics.  We have to remember that the mediastinal pathology is usually responsible of a variable clinical picture, wich is important in the cases of the patients with mediastinal syndromes.

Fascioliasis is a worldwide emerging snail-borne zoonotic trematodiasis with a great spreading capacity linked to animal and human movements, climate change, and anthropogenic modifications of freshwater environments. South America is the continent with more human endemic areas caused by Fasciola hepatica, mainly in high altitude areas of Andean regions. The Peruvian Cajamarca area presents the highest human prevalences reported, only lower than those in the Bolivian Altiplano. Sequencing of the complete rDNA ITS-2 allowed for the specific and haplotype classification of lymnaeid snails collected in seasonal field surveys along a transect including 2007–3473 m altitudes. The species Galba truncatula (one haplotype preferentially in higher altitudes) and Pseudosuccinea columella (one haplotype in an isolated population), and the non-transmitting species Lymnaea schirazensis (two haploty...
