Sedoanalgesia para procedimientos en Unidad de Cuidados Intensivos Pediátricos (UCIP). Farmacología, efectos secundarios y control de calidad / Sedoanalgesia for procedures in Pediatric Intensive Care Unit (PICU). Pharmacology, side effects and quality control

OBJETIVOS: Analizar los fármacos más utilizados para sedoanalgesia en procedimientos realizados en una Unidad de Cuidados Intensivos Pediátricos (UCIP), medir su efectividad (nivel de sedación), efectos secundarios y control de calidad. MATERIAL Y MÉTODOS: Estudio prospectivo, observacional y descriptivo. Se recogieron datos epidemiológicos y clínicos, fármaco/s utilizado/s, nivel de sedación alcanzado, incidencias o efectos adversos y escalas de satisfacción, de pacientes de 0 a 18 años sometidos a procedimientos que precisaron sedoanalgesia. RESULTADOS: Se incluyeron 112 pacientes con una edad media de 8,3 años. El fármaco más utilizado fue el propofol (64,3%), seguido de la asociación de ketamina con midazolam (16,1%) y del sevofluorano (12,5%). En el 70,5% de los pacientes se alcanzó un nivel de sedación profunda, sin diferencias estadísticamente significativas entre los distintos fármacos. Se registraron efectos adversos en un 51,8% de pacientes, principalmente desaturación, con una frecuencia mayor al emplear propofol (p< 0,05). La puntuación en la satisfacción alcanzó el valor máximo en todos los padres encuestados, sin hallarse diferencias significativas en función del procedimiento, fármaco, nivel de sedación o efectos adversos. En el 80% de los profesionales la puntuación alcanzó ese mismo valor. CONCLUSIONES: El fármaco más utilizado y con mayor eficacia es el propofol, aunque se asocia más frecuentemente con efectos adversos. El nivel de sedoanalgesia fue adecuado en el momento de iniciar los procedimientos. El grado de satisfacción es óptimo en la mayor parte de los encuestados, aunque fue registrado en menos de la mitad de los procedimientos

OBJECTIVES: To analyze the drugs most used for sedoanalgesia in procedures performed in a Pediatric Intensive Care Unit (PICU), to measure their effectiveness (level of sedation achieved), the main side effects and to carry out a quality control. MATERIAL AND METHODS: Prospective, observational and descriptive study. Epidemiological and clinical data, drug (s) used, level of sedation achieved, incidences or adverse effects, and satisfaction scales were collected from patients from 0 to 18 years of age who underwent procedures that required sedation and analgesia. RESULTS: 112 patients with an average age of 8.3 years were included. The most widely used drug was propofol (64.3%), followed by the association of ketamine with midazolam (16.1%) and sevofluorane (12.5%). In 70.5% of the patients, a level of deep sedation was reached, with no statistically significant differences between the different drugs used. Adverse effects were recorded in 51.8% of patients, mainly desaturation, with a higher frequency when using propofol (p <0.05). Satisfaction score was maximal in all the parents surveyed, without finding significant differences based on the procedure, drug, level of sedation or adverse effects. In 80% of the professionals the score was also maximal. CONCLUSION: The most used and with the highest efficacy in absolute values drug was propofol, although it was more frequently associated with adverse effects. The level of sedoanalgesia was adequate at the time of initiating the procedures. The degree of satisfaction was optimal in most of the respondents, although it was registered in less than half of the procedures

Efficacy and safety of administering oral misoprostol by titration compared to vaginal misoprostol and dinoprostone for cervical ripening and induction of labour: study protocol for a randomised clinical trial.

BACKGROUND: Among the various methods available, the administration of prostaglandins is the most effective for inducing labour in women with an unfavourable cervix. Recent studies have compared treatment with various titrated doses of oral misoprostol with vaginal misoprostol or dinoprostone, indicating that the use of an escalating dose of an oral misoprostol solution is associated with a lower rate of caesarean sections and a better safety profile. The objective of this study is to assess which of these three therapeutic options (oral or vaginal misoprostol or vaginal dinoprostone) achieves the highest rate of vaginal delivery within the first 24 h of drug administration. METHODS: An open-label randomised controlled trial will be conducted in Araba University Hospital (Spain). Women at ≥41 weeks of pregnancy requiring elective induction of labour who meet the selection criteria will be randomly allocated to one of three groups: 1) vaginal dinoprostone (delivered via a controlled-release vaginal insert containing 10 mg of dinoprostone, for up to 24 h); 2) vaginal misoprostol (25 µg of vaginal misoprostol every 4 h up to a maximum of 24 h); and 3) oral misoprostol (titrated doses of 20 to 60 µg of misoprostol following a 3 h on + 1 h off regimen up to a maximum of 24 h). Both intention-to-treat analysis and per-protocol analysis will be performed. DISCUSSION: The proposed study seeks to gather evidence on which of these three therapeutic options achieves the highest rate of vaginal delivery with the best safety profile, to enable obstetricians to use the most effective and safe option for their patients.

Estudio del patrón de expresión de microRNAs en el hueso osteoporótico / Study of miRNAs expression patterns in osteoporotic bone

Objetivos: Identificar microRNAs (miRNAs) diferencialmente expresados en muestras óseas con fractura osteoporótica respecto a huesos sanos. Material y métodos: Se extrajo RNA total a partir de hueso trabecular fresco del cuello femoral de mujeres sometidas a reemplazo de cadera, ya sea debido a fractura osteoporótica (n=6) o por artrosis en ausencia de osteoporosis (según la DMO) (n=6). Las muestras se hibridaron en un array de miRNAs y se realizaron diagramas de PCA y de mapa de calor. Para la comparación de los niveles de expresión, se fijó como significativo un umbral de cambio de >1,5 veces y un valor p <0,05 en la t de Student (corregido para múltiples pruebas). Resultados: Tanto los análisis de PCA como el mapa de calor mostraron una agrupación de las muestras según si eran de fractura o no. Se detectaron 790 miRNAs en las muestras de hueso, 82 de los cuales estaban alterados en las muestras osteoporóticas. Tras la validación en otro panel de 6 muestras osteoporóticas y 6 no osteoporóticas mediante PCR a tiempo real de los miRNAs más significativos, y para los que existía un ensayo disponible, se confirmaron los miRNAs miR-320a y miR-22-3p. Estos dos miRNAs se detectaron en cultivos de osteoblastos primarios, aunque no mantenían el mismo patrón de expresión que en las muestras de hueso total. Conclusiones: Hemos demostrado que existen diferencias en la expresión de miRNAs en muestras con fractura osteoporótica, lo que abre nuevas perspectivas para la investigación y diseño de nuevas terapias (AU)

Objectives: To identify microRNAs (miRNAs) differentially expressed in bone samples with osteoporotic fracture compared with healthy bones. Methods: Total RNA was extracted from fresh trabecular bone of the femoral neck of women undergoing hip replacement surgery, either because to osteoporotic fracture (n=6) or in the absence of osteoarthritis osteoporosis (based on BMD) (n=6). The samples were hybridized on an array of miRNAs and PCA diagrams and heat map were made. To compare expression levels, >1.5 times and a value p<0.05 Student's T test (corrected for multiple testing) was set as a threshold of significant change. Results: Both PCA analysis and the heat map showed a samples grouping whether there was fracture or not. 790 were detected miRNAs in bone samples, 82 of which were altered in the osteoporotic samples. After validation in another panel of 6 samples 6 osteoporotic and non-osteoporotic by PCR real time of the most significant miRNAs, and for which there was a test available, the miRNAs, miR-320a and miR-22-3p were confirmed. These two miRNAs were detected in cultures of primary osteoblasts, although they did not maintain the same pattern of expression in total bone samples. Conclusions: We have shown that there are differences in the expression of miRNAs in samples with osteoporotic fracture. This opens prospects for research and design of new therapies (AU)

Growing teratoma syndrome after ovarian inmature teratoma: a case report and review of the literature.

Growing teratoma syndrome is an uncommon complication of malignant germ cell cancer, characterised by the development of large tumours during or after chemotherapy, despite normalisation of tumour marker levels and metastasis, which contain only mature teratoma. Given its low incidence, little is data available. The authors present the case of a 15-year-old girl with a growing teratoma and the literature review outlines the current knowledge of its pathogenesis, common sites, diagnosis, natural course, treatment, and prognosis.

Salud sexual en Chile: una aproximación descriptiva al comportamiento y la satisfacción sexual de los chilenos / Sexual health in Chile: a descriptive approach to the behavior and sexual satisfaction of Chileans

ANTECEDENTES: El año 2006, la Organización Mundial de la Salud definió a la "salud sexual" como un estado de bienestar físico, emocional, mental y social en relación a la propia sexualidad. De este modo, corresponde a un concepto más amplio que la ausencia de malestares, disfunciones o enfermedades, relacionándose con un nivel de bienestar general. Pese a la relevancia del concepto, aún es escasa la evidencia empírica al respecto a nivel local. OBJETIVOS: El artículo analiza el concepto de "salud sexual" a nivel de población general en Chile. MÉTODOS: Se diseñó una muestra probabilística, polietápica y estratificada en el Gran Santiago, encuestándose a 767 personas mayores de 18 años, siguiendo la metodología de autorreporte de hogares. RESULTADOS: El estudio evidencia diferencias según género y edad en la mayor parte de las variables relativas a la satisfacción sexual y a conductas sexuales seguras. CONCLUSIÓN: Se concluye que los hombres inician su vida sexual más tempranamente, tienen más parejas sexuales y reportan mayor satisfacción sexual que las mujeres, con excepción de la cohorte más joven. Ellas, a su vez, declaran mayores niveles de protección y cuidado de la vida sexual.

BACKGROUND: In 2006, the World Health Organization endorsed the concept of "sexual health" as a state of physical, emotional, mental and social well-being in relation to sexuality. Thus, it corresponds to a broader concept that the absence of disease, dysfunction or infirmity, being related to a general level of well-being. Despite the relevance of the concept, locally, there is still scarce empirical evidence about it. AIMS: The article analyses the concept of "sexual health" among the Chilean general population. Methods: In order to achieve this objective, a probabilistic, polyphasic and stratified sample was designed for the province of Santiago, being surveyed 767 people over 18 years, through a self-reported method in their own households. RESULTS: The study shows differences by gender and age in both sexual satisfaction and safe sexual behaviours. CONCLUSION: It is possible to conclude that men begin their sexual life earlier, have more sexual partners and report higher sexual satisfaction than women, except for the youngest cohort. Women, in turn, report higher levels of protection and care of sexual life.

Trastorno facticio con síntomas psicológicos. Diagnóstico y tratamiento. ¿Es útil la confrontación? / A case report. Factitious disorder with psychological symptoms. Is confrontation useful?

El trastorno facticio se caracteriza por la producción o invención intencional de síntomas físicos o psicológicos de una enfermedad con el objetivo de asumir el papel de enfermo. Es difícil realizar un diagnóstico adecuado de este trastorno, sobre todo cuando los síntomas simulados son los de una enfermedad psicológica o psiquiátrica. En estos casos suele existir una elevada comorbilidad con otros trastornos mentales, por lo que en ocasiones es complicado diferenciar cuáles de los síntomas son reales y cuáles son facticios. A esto se añade la inexistencia de pruebas objetivas que faciliten la tarea diagnóstica. En este artículo se pretende esclarecer cómo llegar a un correcto diagnóstico del trastorno facticio con síntomas psicológicos, revisar los abordajes terapéuticos descritos en la literatura y analizar la utilidad de cada uno en un caso clínico seleccionado (AU)

Factitious disorder is defined by the intentional production or feigning of physical or psychological symptoms with the objective of assuming the patient role. It is frequently difficult to adequately diagnose this disorder, above all, when the faked symptoms are those of a psychological or a psychiatric disorder. In these cases, there is often high comorbidity with other mental disorders, thus making it difficult to differentiate between real and factitious symptoms. Moreover, the lack of clear objective markers makes assessing the diagnosis even more difficult. In this article, we have aimed to clarify how a correct diagnosis of factitious disorder with psychological symptoms can be reached, to observe the different therapeutic strategies described in the literature and to analyze the utility of each one of them in a given case report (AU)

Rapid and deep control of inflammation in rheumatoid arthritis with infliximab and its correlation with acute-phase reactants.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with predominant joint involvement and possible systemic compromise, which leads to a handicapped status and poor quality of life. An optimal approach to treat RA requires early and intensive intervention with close monitoring of treatment response. Tumor necrosis factor (TNF) blockers are recommended in cases of active RA after the unsuccessful use of effective disease-modifying antirheumatic drugs (DMARDs); even adding them to treatment or replacing these drugs. Anti-TNF therapies have been demonstrated to reduce significant joint damage and to relieve symptoms during a prolonged time (see Scott and Kingsley, 2006). The efficacy of infliximab in an open-label trial is summarized with respect to speed of onset of action, durability of response, and its correlation between clinical and laboratory parameters. Safety for long-term treatment is also summarized. We studied 105 RA patients with more than 3 years' history of disease during 24 months on i.v. infliximab (75 completed study). We evaluated ACR responses at base line, and at 1, 6, 12, 16, 52, 77, and 104 weeks. Morning stiffness, swollen and tender joints, HAQ, SF-36% (PCS/MCS), polymerase chain reaction (PCR), erythrosedimentation rate (ESR), transaminases, rheumatoid factor (RF) levels, hemogram, and adverse events profile were all assessed. The treatment offered rapid and sustained clinical improvements as revealed by ACR responses and marked changes in the parameters previously described. Important changes were made in functional status and acute-phase reactants. Finally, infliximab was considered well tolerated and did not affect the safety profile of this trial.
