Journal of Behavioral and Brain Science (JBBS) , 2013, DOI: 10.4236/jbbs.2013.32023
Abstract:

RTT girls suffer periods of abnormal behavior from early infancy, including irritability and sleep disorders or anxiety in the first years of life, and a more depressed mood after adolescence, all of which influences their quality of life. An association between emotional and behavioral disorders and various neurochemical changes in the synapses of cortical and subcortical brain regions has been established; also, cortisol levels in the blood vary during stress. The main purpose of this study was to improve mood and behavior disorders in RTT patients with venlafaxine (SNRI), and compare the results with citalopram (SSRIs) during 6 - 8 weeks, to determine which drug offered greater efficacy and fewer side effects, as well as to compare them to risperidone, and to correlate cortisol levels in saliva with stress and drug response. Eleven patients, aged 5 to 26 years old, agreed to participate in this study; neuropsychological tests (Mullen and Vineland scales), quality of life and quality of sleep scales, blood tests, EKG and EEG were performed before and after treatment. Only 2 patients completed the three months trial. Improvement in mood and behavior was not statistically significant for patients; differences in neurodevelopment and quality of life or sleep scales were not significant either;

Abstract: Enterotoxigenic Escherichia coli (ETEC) and Shigella are two of the leading causes of diarrhea among children in developing countries. The prevalence of ETEC and Shigella species resistant to antimicrobial agents is increasing. The aim of this study was to determine prevalence and antimicrobial resistance patterns of ETEC and Shigella species among under-five children with diarrhea in an urban region of southeastern Mexico. A cross-sectional study was conducted among under-five children with acute diarrhea from January 2013 to January 2014 at Merida city. Isolation, identification and antimicrobial susceptibility test of ETEC and Shigella species were performed using standard bacteriological protocols. Of 200 stool samples collected, 18 (9.0%) ETEC and 12 (6.0%) Shigella strains were isolated. Among 12 Shigella species Shigellaflexneri founded as 8 (66.7%), followed by Shigellaboydii 4 (33.3%). One hundred percent of ETEC and Shigella isolates showed resistance to ampicillin, carbenicillin and cephalothin. Also, high frequency of resistance for both ETEC and Shigella isolates was observed to nitrofurantoin (100%, 83.3%), respectively. However, when we analyzed the resistance patterns of Shigella by species, S. boydii showed more resistance (8 of 12 antimicrobials tested) in comparison to S. flexneri isolates. Multidrug resistance (MDR) (≥3 drugs) was observed among all ETEC and Shigella isolates, being the aminoglycosides the more effective drugs against these pathogens. In conclusion, these findings indicate that ETEC and Shigella spp. are important etiological agents of diarrhea among under-five children and a high rate of drug resistance, including MDR, to the commonly used drugs was observed in our region.

Abstract: Cuphea glutinosa Cham. et Schltdt. es una especie ampliamente distribuida en América templada, presente en las sierras bonaerenses, potencialmente importante desde el punto de vista industrial y medicinal. El presente trabajo tiene por objeto determinar las sustancias ergásticas presentes en los tallos, los sitios de acumulación de las mismas y las características anatómicas de tallos maduros y jóvenes de plantas creciendo en diferentes condiciones de humedad y luz. Se muestrearon tallos jóvenes y maduros de plantas de Sierra Bachicha, Sierra de los Padres y Sierra de los Difuntos. Se realizaron cortes a mano alzada para el estudio de la anatomía del tallo y la aplicación de test histoquímicos para identificar almidón, grasas-aceites, mucílago y taninos. Se confirma la presencia de grasas-aceites y mucílagos en células de los pelos glandulares y gotas exudadas; amiloplastos y taninos en distintos tejidos. Los tallos jóvenes provenientes de suelos húmedos presentan mayor cantidad de drusas que aquellos de suelos secos, mientras que los tallos adultos de suelos húmedos, mayor cantidad de amiloplastos que aquellos de suelos secos. Los tallos adultos, especialmente aquellos de suelos húmedos presentan mayor abundancia de taninos. Las diferencias estructurales halladas, tanto en tallos jóvenes como en adultos pueden ser atribuidas a las diferentes condiciones ambientales que afectan los sitios individuales de crecimiento.

Revista de Otorrinolaringología y Cirugía de Cabeza y Cuello , 2011,
Abstract: Introducción: La presencia de dehiscencia de canal semicircular superior presenta una notable diferencia entre la incidencia radiológica (del 1% al 19%) y la anatómica (entre 0,4% y 0,6%). Objetivo: El objetivo del trabajo es determinar la incidencia anatómica de la dehiscencia del canal semicircular superior y compararla con la incidencia radiológica. Material y método: Se estudia la incidencia de dehiscencia de canal semicircular superior en 80 cráneos (160 temporales). Resultados: Hemos observado la presencia de una dehiscencia del canal semicircular superior en un cráneo de los 80 estudiados, lo que representó una incidencia del 0,6%. Se discute las posibles causas porque la prevalencia de los estudios radiológicos es marcadamente superior a la de los estudios anatómicos. Conclusión: Es evidente que se realiza un "sobrediagnóstico" de dehiscencias del canal semicircular superior ya que los hallazgos anatómicos están muy lejos de los resultados obtenidos con técnicas de imagen. Introduction: The presence of dehiscence in the superior semicircular canal shows a remarkable difference between radiological (from 1%% to 19%%) and anatomical incidence (between 0,4% and 0,6%) Aim: To determine the incidence anatomical superior semicircular canal dehiscence. Material and method: The incidence of dehiscence in superior semicircular canal in 80 skulls (160 temporal bones) is studied. Results: We have observed the presence of one dehiscence in the superior semicircular canal in one skull from the 80 studied, representing an incidence of 0.6%. The possible causes are discussed because of the prevalence of the radiological studies is highly superior to anatomical studies. Conclusion: It is obvious the over-diagnosis performed about the dehiscences in the superior semicircular canal since anatomical finds are quite different from the results obtained by means of image technics.

Abstract: Fundamento: La vigilancia de la Enfermedad Meningocócica en Canarias es fundamentalmente pasiva, sirviéndose del circuito habitual de las Enfermedades de Declaración Obligatoria. El objetivo de este trabajo incluye describir los atributos cualitativos y cuantitativos del sistema y evaluar la exhaustividad mediante el sistema de captura-recaptura de tres fuentes de información. Métodos: El estudio abarca los a os 1999-2001 en Tenerife. La información se obtuvo de tres fuentes: el Sistema de las Enfermedades de Declaración Obligatoria, los Laboratorios de Microbiología y el Conjunto Mínimo Básico de Datos hospitalario. Se aplicaron los Protocolos de Evaluación de un Sistema de Vigilancia de los Centers of Disease Control and Prevention, de Atlanta. Para la estimación del número de casos se usó un modelo log-linear. Los cálculos de la exhaustividad y los intervalos de confianza al 95% se realizaron en el paquete estadístico SPSS10. Resultados: La sensibilidad del sistema resultó ser del 84,9% y el valor predictivo positivo del 80,4%. El retraso en la notificación (oportunidad) osciló entre los 0,5 y 13 días, con una mediana de 3 días. La aceptabilidad global del sistema ha sido del 76,64%. El valor de la exhaustividad fue del 98,1%. Conclusiones: La vigilancia de esta enfermedad es buena, con una sensibilidad que hablaría de un buen nivel de declaración, reafirmada por la exhaustividad. Aunque el valor predictivo positivo es alto, podría apuntar hacia la rápida instauración de tratamiento antibiótico que impediría la confirmación microbiológica. El sistema es oportuno, permitiendo la rápida adopción de medidas de intervención.
