Respiratory syncytial virus (RSV) is the main pathogen causing lower respiratory tract infections during the first year of life and causes high rate of hospitalizations in children under 12 months. Its clinical presentation and emergence as severe outbreaks in preterm units represents high risk of morbidity and mortality. Two cases are presented and analysis of importance of early diagnosis, ventilatory management and hygienic measures is done in order to reduce hospitalization and prevent presentation of new cases in a Lima, Peru’s neonatal intensive care unit.

Water contaminated in plastic bottles was radiated with solar light. lt has analyzed the probable number by unit of volume of Fecal and Total Coliforms. The obtained results show that with a solar irradiation of average 700 W/m2 the disinfection is obtained in few hours.

Bulk aerosol samples collected during cruise M91 of FS Meteor off the coast of Peru in December 2012 were analysed for their soluble trace metal (Fe, Al, Mn, Ti, Zn, V, Ni, Cu, Co, Cd, Pb, Th) and major ion (including NO−3 and NH+4) content. These data are among the first recorded for trace metals in this relatively poorly studied region of the global marine atmosphere. To the north of ∼ 13◦ S, the concentrations of several elements (Fe, Ti, Zn, V, Ni, Pb) appear to be related to distance from the coast. At the south of the transect (∼ 15–16◦ S), elevated concentrations of Fe, Cu, Co and Ni were observed. These may be related to the activities of the large smelting facilities in the south of Peru or northern Chile. Calculated dry deposition fluxes (3370–17 800 and 16–107 nmolm−2d−1 for inorganic nitrogen and soluble Fe respectively) indicated that atmospheric input to...

The Mesozoic rocks of southern Peru comprise a Middle Jurassic to Early Cretaceous sedimentary sequence deposited during a time interval of approximately 34 Myr. In Tacna, these rocks are detrital and constitute the Yura Group (Callovian to Tithonian) and the Hualhuani Formation (Berriasian). Basing on robust interpretation of facies and petrographic analysis, we reconstruct the depositional settings of such units and provide a refined stratigraphic framework. Accordingly, nine types of sedimentary facies and six architectural elements are defined. They preserve the record of a progradational fluvial system, in which two styless regulated the dispersion of sediments: (i) a high-to moderate-sinuosity meandering setting (Yura Group), and a later (ii) incipient braided setting (Hualhuani Formation).The Yura Group (Callovian-Tithonian) represents the onset of floodplain deposits and lateral ...

Meteor cruise M91 was supported by the BMBF projects SOPRAN II and III (FKZ 03F0611A and FKZ 03F662A). We thank the Peruvian authorities for authorising us to conduct the study in their territorial waters. We also would like to thank our Peruvian colleagues from IMARPE (M. Graco, A. Bernal, G. Flores, and V. León) for their logistical support to our work. Sample analysis was funded by the UK Natural Environment Research Council (NERC) through grant NE/H00548X/1 and by the School of Natural Sciences, University of East Anglia. We gratefully acknowledge the NOAA Air Resources Laboratory for the provision of the HYSPLIT transport and dispersion model and the READY website (http://www.arl.noaa.gov/HYSPLIT.php) and two anonymous reviewers for their comments on our manuscript.

The Cenozoic rocks lying in the Province of Tacna (18° S), southern Perú, represent approximately 600 m of stratigraphic thickness. This stacking groups the Sotillo (Paleocene), Moquegua Inferior (Eocene), Moquegua Superior (Oligocene), Huaylillas (Miocene) and Millo formations (Pliocene), and these are the sedimentary fill of the Moquegua Basin. The sediments of the three latter formations are organized into nine sedimentary facies and five architectural elements. Their facies associations suggest the existence of an ancient highly channelized multi-lateral fluvial braided system, with upward increase of pyroclastic and conglomeratic depositions. The heavy mineral spectra make each lithostratigraphic unit unique and distinguishable, being the sediments of the Moquegua Superior Formation rich in garnets, titanites and zircons; while the sediments of the Huaylillas and Millo formations ...

Quality of life after thyroid gland surgery is as important as disease control. To improve cosmetic results and patient satisfaction, endoscopic approaches are used using incisions outside the cervical region. Endoscopic transoral thyroidectomy does not leave any visible scarring on the skin. We present the case of a 29-year-old female patient with a benign thyroid gland tumor with compressive symptoms and aesthetic concerns, who underwent a right hemithyroidectomy by means of an endoscopic transoral vestibular approach in a time of 150 minutes and minimal bleeding, without complications in the postoperative period. The transoral endoscopic vestibular approach for endoscopic resection of the thyroid gland is safe and the results are comparable with the open surgical technique, with a better cosmetic result and improved quality of life.

Se ha aplicado la tecnología de Desinfección Solar en Unidades Individuales (DSAUI) a aguas del asentamiento humano Tambo Pariachi en Huaycán. Los valores iniciales de contaminación encontrados (coliformes) reflejan que las aguas no son aptas para el consumo humano, pudiendo causar múltiples enfermedades en la población. El agua contaminada fue expuesta al sol dentro de botellas de plástico PET. Los resultados indican que la descontaminación se debe a una sinergia entre la temperatura dentro de la botella de plástico y la componente ultravioleta de la radiación solar. Se observó un cambio de las botellas PET debido a un envejecimiento acelerado que produce la luz ultravioleta, que influye directamente sobre la eficiencia de desinfección de las aguas. El método empleado es sencillo y económico, y podría ser empleado de manera masiva por la población, como una alternativa p...

The hyaluronidase from Bothrops atrox venom was purified and characterized. The effect of monovalent and divalent ions on their catalytic activity was studied, showing that the magnesium ion (150 mM) increases de activity in 40%, while glycine inhibits it by 44 %. The enzyme lacks toxic activity, when administered in albino mice in toxicity tests, but increases the hemorrhagic action of the total venom on the skin of these animals. The polyvalent botropic antivenom, was able to recognize components of the total venom of B. atrox, as well as the purified enzyme, in immunodiffusion assays. The cDNA coding for hyaluronidase from the venom of B. atrox was obtained from mRNA extracted of the fresh venom, and sequenced. The analysis of the cDNA, of 2020 bp, shows that it contains an ORF of 1350 bp that codes for a pre-enzyme of 449 amino acids, which probably is processing resulting in a matur...

Snakebite envenoming is a neglected public pathology, affecting especially rural communities or isolated areas of tropical and subtropical Latin American countries. The parenteral administration of antivenom is the mainstay and the only validated treatment of snake bite envenoming. Here, we assess the efficacy of polyspecific anti-Bothrops serum (α-BS) produced in the Instituto Nacional de Salud (INS, Peru) and at the Fundação Ezequiel Dias (FUNED, Brazil), to neutralize the main toxic activities induced by five medically-relevant venoms of: Bothrops atrox, B. barnetti, and B. pictus from Peru, and the Brazilian B. jararaca and B. leucurus, all of them inhabiting different geographical locations.

Las redes de colaboración de multicentros son esenciales para el avance de la investigación y mejorando la atención clínica de variedad de condiciones. La redes de investigación son particularmente importantes para las infecciones del sistema nervioso central, las cuales son difíciles de estudiar. Se revisa nuestra experiencia de desarrollo de redes de investigación en encefalitis en doce hospitales de cinco ciudades peruanas desde el año 2009, y se presentan sugerencias prácticas para ayudar a otros grupos de investigación en áreas de recursos limitados.
