    Abstract Adenovirus (HAdV) F41 is a common cause of gastroenteritis and has rarely been reported associated with disseminated disease. In this report, an adult patient with a history of ulcerative colitis, cryptogenic cirrhosis, stage III adenocarcinoma, high-grade diffuse large B-cell lymphoma on chemotherapy was diagnosed with disseminated adenovirus infection. HAdV DNA was quantified in stool, plasma, and urine with viral loads of 7, 4, and 3 log10 copies/mL, respectively. The patient鈥檚 course was rapidly progressive and he passed away 2 days after initiation of antiviral therapy. The patient鈥檚 infecting virus was characterized as HAdV-F41 by whole genome sequencing

    Isradipine, a new and potent antihypertensive dihydropyridine calcium antagonist, was evaluated in 132 patients (66.7% females and 33.3% males) withe the clinical diagnosis of mild to moderate hypertension, in an open multicenter study that took place in the hypertension, in an open multicenter study that took place in the hypertension clinics of several peruvian hospitals. The protocol include a wash out or diagnosis confirmation period of two weeks followed by 12 weeks of treatment with 2.5 mg isradipine twice daily.聽 The patients mean age was 56.7 (+-6.3), weight 66.9 kg (+- 11.0) and height 160 (+- 9.0). 30.3% of the patients had associated diseases, 86.4% had been previously treated for hypertension and 85.8% had a clinical diagnosis of arterial hypertension for more than one year.聽 After 90 days of treatment there was a mean decrease of 28.8 mmHg in the diastolic arterial blood, from 168.5 (+- 16.7) to 140.0 (+- 11.4) mmHg (P< 0000). In relation to the sistolic blood pressure, the difference was also significative (P<0000), from 102.3 +- 5.11) to 84.6 (+-5.9) mmHg, an average of 17.4 mmHg. There were no significant changes in heart rate. Isradipine was well tolerated. The most frecuent problems were in relation to: flashing and headaches, but they were all transitory and they diminish with the time of treatment, it was only necessary to stop the treatment in 5.3% of the patients because of adverse events. The laboratory test did not show any changes at the end of the 90 days of treatment. It is concluded that isradipine is a new antihypertensive drug that presents a very good efficacy and is well tolerated in the treatment of mild to moderte arterial hypertension.Un potente calcio antagonista del tipo de los dihidropiridinas el isradipino, fue evaluado en 132 pacientes ambulatorios (66,7% del sexo femenino y 33,3% del sexo masculino) con el diagn贸stico cl铆nico de hipertensi贸n arterial leve a moderada, mediante un estudio multic茅ntrico abierto no comparativo, en diversos Hospitales de Lima-Per煤. El protocolo de estudio incluy贸 un per铆odo inicial de dos semanas de "lavado" o confirmaci贸n diagn贸stica, seg煤n el caso, seguido por 12 semanas de tratamiento con Isradipino 2.5mg dos veces al d铆a.聽 La edad Promedio del grupo fue de 65.7 a帽os +- 6.3), peso promedio 66.9 Kgs (+- 11.0) y talla 1.60cms (+- 9.0). El 30.3% de los pacientes ten铆an diversas enfermedades asociadas, 86,4% hab铆an sido tratados previamente por hipertensi贸n arterial y 85.8% ten铆an hipertensi贸n arterial diagnosticada hacia m谩s de un a帽o. Luego de noventa d铆as de tratamiento con Isradipino se encontr贸 una disminuci贸n promedio de 28.8 mm/lg en la presi贸n arterial sist贸lica, la que decreci贸 de 168.5 (+- 16.7) a 140.0 (+- 11.4) mmHg (p<0000) ya que disminuy贸 de 102.3 (+- 5.11) a 84.6 (+- 5.9) mmHg, con una reducci贸n promedio de 17.4 mmHg. No se observaron variaciones cl铆nicamente significativas en la frecuencia card铆aca.聽 Isradipino fue bien tolerado. Los efectos secundarios m谩s frecuentes fueron: bochornos y cefalea, todos ellos pasajeros y que fueron disminuyendo en el curso del tratamiento, necesitando suspender la droga solo en el 5.3% de pacientes. Los par谩metros de laboratorio cl铆nico estudiados, as铆 como el electrocardiograma y el fondo de ojo, no presentaron modificaciones.聽 Se concluye que el Isradipino es un nuevo f谩rmaco de muy buena eficacia antihipertensiva, bien tolerado y seguro en el tratamiento de la hipertensi贸n arterial leve a moderada

    Caries is one of the diseases of infectious nature, chronic transmissible very prevalent in Peru, related to the presence of Streptococcus mutans, hygienic and nutritional habits. Objective: The purpose of this study was to determine the presence of genotype C in Streptococcus mutans in Peruvian children and adolescents, using the PCR-Multiplex technique; and its association with the prevalence of dental caries. Materials and methods: The study was done with a sample of 78 children and adolescents of both sexes from Lima. The study consisted of two phases, on the first one the stimulated saliva was obtained, for the bacterial culture, the same ones that were grown on Mitis Salivarius agar with bacitracin and sulfisoxasol. On the second phase, genotyping was carried out according to its enzymatic profile. For the extraction of DNA, the Gene Extraction Kit GG-1 Bacterial DNA was used, for which cultures of Streptococcus sp strains were performed in the BHI broth with sucrose at 37潞C for 24 hours. Results: The presence of Streptococcus mutans was evidenced in 59 (75.6%) of 78 saliva samples. The results of the genotyping by PCR Multiplex demonstrate the presence of 22 saliva samples of Streptococcus mutans with genotypes C (37,297%) and 37 samples 62, 71 % without this Genotype. Conclusions: The results showed that the presence of genotype C is not related to sex, age group or the presence of dental caries.La caries es una de las enfermedades de naturaleza infecciosa, cr贸nica transmisible muy prevalente en el Per煤, relacionada a la presencia del Streptococcus mutans, los h谩bitos de higiene y nutricionales. Objetivo: El prop贸sito de este estudio fue determinar la presencia del genotipo C en el Streptococcus mutans en ni帽os y adolescentes peruanos, utilizando la t茅cnica PCR- Multiplex; y su asociaci贸n con la prevalencia de caries dental. Material y m茅todo: Se trabaj贸 con una muestra de 78 ni帽os y adolescentes de ambos sexos de Lima. El estudio consisti贸 en dos fases, en la primera se obtuvo la saliva estimulada, para el cultivo bacteriano, las mismas que fueron sembradas en agar Mitis Salivarius con bacitracina y sulfisoxasol.

    The aim of this study was to determine the level of knowledge on oral health of mothers and their relationship with oral health status of their children under five years old, who were admitted to hospitals of Ministry of Health (MINSA) and Social Security (ESSALUD). Were taken into consideration ethical standards. This is an analytical and cross-sectional study. The sample consisted of mothers with children under five years of age (n 143). Was used not randomized quota sampling. Was applied a structured questionnaire to collect information about the level of mother麓s knowledge on oral health and a diagnostic sheet for oral health status of children under five. Clinical examination was performed with artifitial light, using epidemiological indices: Dental Caries Index (dmft), and the Simplified Oral Hygiene Index by Greene-Vermillion (OHI-S). There was no significant association between level of knowledge on oral health who have mothers with the oral health status of children under five years of age (p 0.16). Mothers had knowledge among regular and good in 77.6 % however this was not reflected in the oral health of children. Was concluded that it should work a program with emphasis on promoting preventive promotional positive attitudes towards oral health care from an early age not only to ensure the spacing of permanent teeth, but also to ensure the child鈥檚 feeding and their growth and bio-psycho-social development.El objetivo de este estudio fue determinar el nivel de conocimientos sobre salud bucal de las madres de familia y su relacion con el estado de salud bucal del ni帽o menor de cinco a帽os de edad, que acude a establecimientos hospitalarios del Ministerio de Salud (MINSA) y Seguro Social (ESSALUD), teniendo en consideraci贸n los criterios y normas 茅ticas establecidas; siendo un estudio de tipo anal铆tico transversal. La muestra estuvo constituida por madres con sus hijos menores de cinco a帽os de edad (n 143). El tipo de muestreo fue no probabil铆stica por cuotas. Se aplic贸 una encuesta estructurada para la recolecci贸n de informaci贸n del nivel de conocimientos sobre salud bucal de las madres de familia y ficha de diagn贸stico del estado de la salud bucal del ni帽o menor de cinco a帽os, que fueron examinados cl铆nicamente a luz artificial, utilizando los 铆ndices epidemiol贸gicos de: Caries Dental (ceo-d), Placa bacteriana (Greene y Vermillion. IHO-S). No se hall贸 asociacion significativa entre el nivel de conocimientos sobre salud bucal que poseen las madres, con el estado de salud bucal del ni帽o menor de cinco a帽os de edad (p 0,16). Si bien las madres poseen conocimientos entre regular y bueno en un 77.6 %, estos no son aplicados adecuadamente, por lo que se debe trabajar dando 茅nfasis en todo programa preventivo promocional para propiciar actitudes positivas hacia el cuidado de la salud bucal, desde temprana edad, resaltando el rol que cumple la dentici贸n temporal, no solo para garantizar el espacio de los dientes permanentes, sino mucho m谩s como es la alimentaci贸n del ni帽o y el rol que juega para su buen crecimiento y desarrollo bio-psico-social, logrando as铆 estilos de vida adecuados

    Clinical data suggesting that larger decreases in low density lipoprotein cholesterol (LDL-C) result in greater reductions in coronary heart disease events have led to the establishment of aggressive LDL-C targets for the treatment of hypercholesterolemia. In view of this, the efficacy and safety of a new maximum dose of simvastatin, 80 mg, were evaluated in 9 studies involving 2819 hypercholesterolemic patients. This report focuses on the combined results from the 4 main or Pivotal studies in which a total of 1936 patients received simvastatin 40 or 80 mg for 36 to 48 weeks. The Pivotal studies had similar randomized, multicenter, controlled, double-blind, parallel-group designs. Their combined results demonstrated a significant advantage in the LDL-C-lowering effect for the 80 mg dose. At week 24, the mean percentage reductions (95% confidence intervals) from baseline in LDL-C for the 40 and 80 mg groups were -39.8% (-40.9, -38.7) and -45.7% (-46.5, -45.0) respectively (p 3 times the upper limit of normal/ULN) and myopathy (muscle symptoms plus creatine kinase increase > 10 times ULN) occurred infrequently with both doses. Simvastatin 80 mg had a comparable efficacy and safety profile in women and men as well as in non-elderly and elderly patients. Simvastatin 80 mg provides additional LDL-C and triglyceride reductions compared to the 40 mg dose and has an excellent safety and tolerability profil
