ABSTRACT

Abstract Lake Laguna Santa Elena, a freshwater body, located in mid-south of Chile, is an environmental asset used as a water resource by the agricultural and touristic sector and is the habitat for a wide variety of endemic avifauna. The objective of this study was to assign a monetary value to this lacustrine body, using the methodology of AMUVAM (Multicriteria Analysis of Environmental Active Values). The information was collected through the application of surveys to a panel of experts involved in the use of the environmental resource. The result obtained with the AMUVAM method corresponds to the US $ 17,780,686, a figure that represents an estimated value of the TEV (Total Economic Value) of the environmental asset. This study, a pioneer in the Region, will support decision making, allowing an adequate management of this critical water resource.

ABSTRACT

La miastenia gravis es una enfermedad neuromuscular crónica debida a deficiencia de transmisión nerviosa en la unión neuromuscular, de origen generalmente autoinmune en el adulto, que se caracteriza por grados variables de debilidad de los músculos esqueléticos del cuerpo, que aumenta durante los períodos de actividad y disminuye después de períodos de descanso. Sin embargo en la infancia cobran especial relevancia los síndromes miasténicos congénitos, que encuentran su origen en mutaciones de genes que codifican proteínas que juegan papeles clave en el mantenimiento de la transmisión neuromuscular, teniendo edad de inicio, distribución de debilidad y respuesta a tratamiento variables. Se presentan tres casos con el objetivo de describir el comportamiento clínico de la enfermedad y la utilidad de estudios complementarios ya que es de suma importancia su precoz identificación y tratamiento. Palabras claves: Miastenia gravis, test de estimulación repetitiva, ptosis palpebral, unión neuromuscular, pares craneanos


Myasthenia gravis is a chronic neuromuscular disease due to deficiency of nerve transmission in the neuromuscular junction, usually of an autoimmune origin in the adult, which is characterized by varying degrees of weakness of the skeletal muscles of the body, which increases during periods of activity and decreases after periods of rest. In childhood, however, congenital myasthenic syndromes, which find their origin in mutations of genes that encode proteins that play key roles in maintaining neuromuscular transmission, which may have a varying age of onset, distribution of weakness and response to treatment, are particularly relevant. Three cases are presented with the aim of describing the clinical presentation and course of the disease and the usefulness of complementary studies, since its early diagnosis and treatment is of paramount importance.Keywords: Myasthenia gravis, repetitive stimulation test, palpebral ptosis, neuromuscular junction, cranial pairs.

Introducción: El Staphylococcus Aureus constituye un agente etiológico frecuente de intoxicaciones alimentarias y se encuentra asociado a diversos alimentos. Objetivo: Describir la frecuencia de portación de Staphylococcus Aureus en manipuladores de alimentos de restaurantes de Asunción durante el 2017. Metodología: Se realizó un estudio observacional, prospectivo, descriptivo de corte transversal a manipuladores de alimentos de restaurantes de Asunción durante los meses de mayo a junio del 2017. Se realizaron tres hisopados nasales a cada uno de los 30 manipuladores de alimentos para determinar si la portación era intermitente, permanente u ocasional. Al mismo tiempo fueron realizadas encuestas donde se midieron variables demográficas. Resultados: La prevalencia de portación de Staphylococcus Aureus fue del 33,3 % (10), siendo el 40% (4) esporádica e intermitente y el 20% (2) permanente. En cuanto a las características demográficas de los manipuladores,el 56,66% (17) fueron del sexo masculino, eran solteros 43,33% (13) y el 50% (15) contaban con estudios secundarios completos. El promedio de edad de 29 de los manipuladores fue de 39,5 años con un rango comprendido entre 18 y 85 años. El 23,33% (7) utilizaban guantes a la hora de manipular los alimentos. Además, se pudo observar que el 26,66% (8) utilizaba gorros. Llamó la atención que el 30% (9) de los encuestados no presentaban uñas limpias durante la manipulación. Palabras clave: Staphylococcus Aureus; manipuladores; alimentos.


Introduction: Staphylococcus Aureus is a frequent etiologic agent of food poisoning and is associated with various foods. Objective : To describe the frequency of Staphylococcus Aureus in food handlers of restaurants in Asunción during 2017. Methodology: An observational, prospective, descriptive, cross-sectional study was carried out on food handlers in restaurants in Asuncion during the months of May to June 2017. Three nasal swabs were made to each of the 30 food handlers to determine if the carriage was intermittent, permanent or occasional. At thesame time, surveys were carried out where demographic variables were measured. Results: The prevalence of carrying Staphylococcus Aureus was 33.3% (10), being 40% (4) sporadic and intermittent and 20% (2) permanent. Regarding the demographic characteristics of the manipulators, 56.66% (17) were male, were single 43.33% (13) and 50% (15) had complete secondary education. The average age of 29 of the manipulators was 39.5 years with ranger between 18 and 85 years. 23.33% (7) used gloves when handling food. In addition, it was observed that 26.66% (8) used caps. It was noted that 30% (9) of theres pondents did not have clean nails during handling. Keywords: Staphylococcus Aureus; manipulators; food.

ABSTRACT

Both the presence of owned dogs and stray dogs allows the spread of Toxocara, a parasite whose eggs can be found in soil, water and food. Animals, including horses, serve as definitive and paratenic hosts. In México, where consumption of horse meat is common, Toxocara is a zoonotic parasite. The aim of this study was to identify the presence of anti-Toxocara antibodies in work horses and horses intended for human consumption by ELISA. ELISA was chosen for analysis as paratenic hosts do not shed Toxocara eggs in their feces. Blood samples were collected from a total of 188 horses, 94 of which were work horses and 94 horses from the slaughter house. Samples were analyzed by ELISA, and the general equine seroprevalence was found to be 44.6% (n = 188). Adult horses for slaughter had a 61.7% greater presence of anti-Toxocara antibodies (p = 0.006). Toxocara IgG antibodies were found in horses, confirming that horses are paratenic hosts and possible sources of infection for other animals and people.(AU)


Tanto a presença de cães com dono quanto de cães vadios permitem a disseminação de Toxocara, e o parasita está presente no solo, na água e nos alimentos. Animais, incluindo cavalos, apresentam-se como hospedeiros definitivos e paratênicos. No México, o consumo de carne de cavalo é comum, e Toxocara é um parasita zoonótico. ELISA foi escolhido para análise, já que hospedeiros paratênicos não jogam ovos de Toxocara em suas fezes. O objetivo deste estudo foi identificar a presença de anticorpos anti-Toxocara por ELISA, em cavalos de trabalho e em cavalos para o consumo humano. As amostras de sangue foram retiradas de 188 cavalos: 94 cavalos de trabalho e 94 cavalos de trabalho do matadouro. Soros dos animais foram analisados por ELISA e 44,6% dos equinos apresentaram anticorpos anti-Toxocara. Cavalos adultos para abate têm 61,7% mais elevada a presença de anticorpos anti-Toxocara (P = 0,006). Anticorpos IgG Toxocara foram encontrados em cavalos, confirmando cavalos paratênicos como hospedeiros e possíveis fontes de infecção para outros animais e pessoas.(AU)

ABSTRACT

Vogt-Koyanagi-Harada (VKH) syndrome is a systemic inflammatory disease that causes chronic and bilateral granulomatous panuveitis, usually described in adults. Objectives: To describe manifestations and complications of VKH in pediatric patients. Methods: Retrospectivedescriptive study upon patients <14 years-old with VKH, attended from January 1985 to July 2010 in three different centers. Results: A total of 17 patients (34 eyes) were studied; 9 (53%) female. The mean age was 10.8 years-old. Among extraocular manifestations; neurological (71%), dermatological (29%) and auditive (24%) signs were observed. Ocular findings included optic-disc involvement (94%), anterior uveitis (79%), choroiditis (77%), serous retinal detachment (71%) and vitritis (71%). Initial visual acuity (VA) was ≤0.05 in 47% of cases and ≥0.6 in 12% of patients. 71% presented complications: glaucoma (20 eyes), sinechiae (10 eyes), maculopathy (6 eyes) cataract (5 eyes) and ptisis bulbi (1 eyes). 35% received only corticosteroids and 65% inmunosupressive drugs. After treatment, 6% had VA ≤0.05 and 59% ≥0.6. Ten patients (59%) recurred: 30% compromising posterior pole, and 50% recurred >3 times. Conclusions: VKH in children is infrequent. It presents with optic-disc involvement and complications of posterior pole. It requires a high degree of suspicion, quick evaluation and early treatment, which include inmunosupressive and extended corticosteroid therapy. Nevertheless, a high rate of recurrence is seen among this group of patients. (AU)

ABSTRACT

Se analizaron características morfológicas relacionadas con el fruto, espinas, endocarpio y semilla, así como parámetros fisicoquímicos y nutricionales (humedad, proteínas, ºBrix, fibra alimentaria, cenizas, pH, acidez, ácido ascórbico, compuestos fenólicos totales, minerales: Na, K, Ca y Mg y elementos traza: Fe, Cu, Zn y Mn), en muestras de chayota (Sechium edule) pertenecientes a 7 entradas cultivadas en las islas de Tenerife y La Palma (España) y cosechadas durante el período comprendido entre junio y noviembre de 2005. Se observaron diferencias importantes en la composición química y características morfológicas entre las diferentes entradas de chayota estudiadas. La entrada 4 destacó por su alto contenido en minerales y sólidos solubles totales (ºBrix) y bajo contenido en agua, mientras que la entrada 1 presentó altos contenidos en Na, cenizas y ácido ascórbico. El contenido de humedad y de ácido ascórbico varió en función de la parte del fruto analizada, sin embargo, los contenidos de compuestos fenólicos y de cenizas no fueron dependientes de las partes. La fecha de muestreo mostró una gran influencia sobre la composición química, observándose las mayores diferencias en las muestras cosechadas en el mes otoñal de noviembre respecto a las restantes cosechadas en meses estivales. El análisis discriminante permitió diferenciar las muestras de chayota en función de la entrada y fecha de muestreo, por lo que es una herramienta muy útil para la caracterización de muestras(AU)


Morphological and chemical composition characterization of chayotas (Sechium edule) grown in the Canary Islands (Spain). Morphological characteristics related to the fruit, thorns, endocarp and seed, as well as physicochemical and nutritional parameters (moisture, protein, ºBrix, fiber, ash, pH, acidity, ascorbic acid, total phenolics, minerals: Na, K, Ca and Mg, and trace elements: Fe, Cu, Zn and Mn) were analyzed in samples of chayote (Sechium edule) belonging to 7 accessions grown on the islands of Tenerife and La Palma (Spain) and harvested during the period between June and November 2005. Significant differences in chemical composition and morphology between the chayote accessions studied were observed. The accession 4 features a high mineral content and soluble solids (Brix degree) and low water content, while the accession 1 had high contents of Na, ash and ascorbic acid. The moisture content and ascorbic acid varied depending on the portion of the fruit analyzed, however, the contents of phenolic compounds and ash were not affected. The sampling date showed a great influence on the chemical composition, the greatest differences observed in the samples harvested in the month of November autumn, with respect to the remaining summer months. Discriminant analysis allowed differentiate samples chayota according to the accession and sampling date, so it is a very useful tool for the characterization of these samples(AU)

ABSTRACT

Introducción. El efecto que tiene la lactancia materna y la alimentación complementaria sobre la prevalencia de las enfermedades alérgicas ha mostrado resultados inconsistentes. Objetivo. Evaluar el efecto de la lactancia materna y el momento de inicio de la alimentación complementaria en la prevalencia de las enfermedades alérgicas. Población y métodos. Estudio transversal analítico con base poblacional realizado en niños de 6 a 12 años de edad inscriptos en escuelas primarias, seleccionados mediante muestreo polietápico. Se aplicó a sus padres o tutores un cuestionario estructurado para identificar enfermedades alérgicas (asma, rinitis alérgica o dermatitis atópica), antecedente de lactancia materna prolongada y edad de inicio de la alimentación complementaria. La búsqueda de asociaciones entre variables se realizó mediante regresión logística. Resultados. Se incluyeron 740 niños. La frecuencia de lactancia e" 6 meses fue 73,4% y de alimentación complementaria con d" 4 meses fue 31,9%. La lactancia materna prolongada no tuvo efecto sobre la prevalencia de las enfermedades alérgicas. Se observó un efecto protector en la frecuencia de la dermatitis atópica cuando el inicio de la alimentación complementaria era tardío, OR ajustado= 0,36; IC95%: 0,1-0,8 (p 0,019). Conclusiones. El efecto protector de la lactancia materna sobre la prevalencia de las enfermedades alérgicas no pudo ser comprobado. La prevalencia de dermatitis atópica es menor con un comienzo tardío de la alimentación complementaria.


Introduction. The effect that breastfeeding and complementary feeding practices have on the prevalence of allergic diseases has shown inconsistent results. Objective. To assess the effect of breastfeeding and the initiation of complementary feeding on the prevalence of allergic disease. Population and Methods. Analytical, crosssectional population-based study conducted in 6-12 year old children attending primary school and selected through a multistage sampling technique. A structured questionnaire was administered to parents or tutors to identify allergic diseases (asthma, allergic rhinitis, or atopic dermatitis), a history of prolonged breastfeeding and age at initiation of complementary feeding. A logistic regression analysis was used to establish associations among variables. Results. A total of 740 children were included. The frequency of breastfeeding for >6 months was 73.4%, and of complementary feeding at <4 months old was 31.9%. Prolonged breastfeeding showed no effect on the prevalence of allergic diseases. A protective effect was observed on the frequency of atopic dermatitis when complementary feeding was initiated late, adjusted OR= 0.36, 95% confidence interval (CI): 0.1-0.8 (p 0.019). Conclusions. The protective effect ofbreastfeeding against the prevalence of allergic diseases has not been demonstrated. There is a reduction in the prevalence of atopic dermatitis when complementary feeding is started late.

ABSTRACT

El presente artículo es producto de una investigación de doctorado de corte cualitativo y con enfoque psicoanalítico. Se proponen cuatro momentos de la sexuación en la hija de una pareja de hombres homoeróticos y se abordan a profundidad los primeros dos momentos. La sexuación es entendida como la posibilidad de que alguien llegue a declarar un sexo y una elección de partenaire sexual. Los primeros vínculos, las asignaciones provenientes del otro y la separación-interdicción que pone límite al goce incestuoso entre padres e hijos son aspectos que juegan un papel decisivo en la sexuación. Dentro de los cuatro momentos de la sexuación se encuentran articulados tres planos de la diferencia localizables en el caso, estos son: la diferencia niño-adulto, la diferencia de género y la diferencia de los sexos. La articulación de estos tres planos de la diferencia, abre la posibilidad de pensar en posicionamientos sexuados diversos y singulares que cuestionan los esencialismos y las dicotomías tradicionales.


The present article is a qualitative research result. It proposes, from the psychoanalytic perspective, four sexuation moments for the daughter of a homoerotic men couple. Sexuation is defined as the process a person goes through to identify themselves with a sex and choosing a sexual partner. In this matter, the first relationships, the assignations of the other and the separation-interdiction that puts a limit to the incestuous pleasure between parents and children are factors that play a key role in sexuation. In the four moments of sexuation, there are articulated three difference levels: the child-adult difference, the gender difference and the difference between sexes. The configuration of these three difference levels, allows the possibility to think about diverse and unique sexual identity placements that challenge the traditional dichotomy.

ABSTRACT

Este trabajo tuvo como objetivo determinar la presencia de micosis superficiales (MS) en la etnia Yanomami de Mawaca, estado Amazonas. De 176 personas examinadas, 64 mostraron lesiones sospechosas de MS, obteniendo 65 muestras: 10 de pitiriasis versicolor (PV) y 55 de dermatofitosis. El estudio micológico consistió en realizar exámenes directos, cultivos en agares micológicos, perforación del pelo in vitro, pruebas de ureasa y agar púrpura de bromocresol-glucosa-sólidos lácteos (Agar BCP-MS-G). De las 10 muestras sospechosas de PV, 3 fueron positivas, dos de niños menores de 10 años y una de un adulto, todos con lesiones en cara. En 36 raspados obtenidos se observaron hifas hialinas septadas. Se aislaron 52 colonias sospechosas de dermatofitos y de éstos, uno fue compatible con el Complejo Microsporum gypseum, de una lesión en la rodilla de un adulto. Las 51 restantes pertenecieron al Complejo Trichophyton rubrum, de los cuales, nueve perforaron el pelo in vitro, 24 hidrolizaron la urea y ninguno alcalinizó el medio Agar BCP-MS-G; la forma clínica fue tinea corporis y las lesiones se localizaron principalmente en espalda y oreja en adultos y niños, respectivamente. Estos resultados revelan la existencia de MS en la población Yanomami, sirviendo de base para futuros estudios epidemiológicos.


The purpose of this study was to determine the presence of superficial mycoses (SM) in the Yanomami ethnicity at Mawaca, Amazon State. Of 176 persons examined, 64 showed suspicious SM lesions, from which we obtained 65 samples: 10 pytiriasis versicolor (PV) and 55 dermatophytosis. The mycological study consisted in carrying out direct examination, culture in mycological agar, in vitro hair perforation, and urease and bromocresol purple-milk solids glucose agar (BCP-MS-G Agar) tests. Of the 10 PV suspicious lesions, 3 were positive, two in children under 10 years old and one in an adult, all with face lesions. In 36 scrapings we saw septate hyaline hyphae. Fifty-two dermatophyte suspicious colonies were isolated and of these, one was compatible with the Microsporum gypseum Complex, from a lesion on the knee of an adult. The other 51 belonged to the Trichophyton rubrum Complex, of which nine were in vitro hair perforations, 24 hydrolized urea, and none alkalinized the BCP-MS-G agar medium; the clinical form was tinea corporis and the lesions were mainly localized at the back and ears in children and adults respectively. These results reveal the existence of SM in the Yanomami population, serving as basis for future epidemiological studies.

ABSTRACT

La ictericia es un problema muy frecuente en las unidades de recién nacidos. En este documento se presenta el caso de un neonato que cursó con hiperbilirrubinemia, inicialmente con predominio de la bilirrubina indirecta y posteriormente con anemia, hepatomegalia, aumento de la bilirrubina directa, alteración de la función hepática, disfunción tubular renal, cataratas y lesiones en la sustancia blanca del SNC. Se descartaron diversas causas de hiperbilirrubinemia directa en el neonato. Se encontró positiva una prueba de azúcares reductores en orina que resultó ser galactosa en la cromatografía en capa fina. Se documentó marcada reducción de la actividad enzimática de galactosa uridil transferasa, con lo cual se confirmó el diagnóstico de galactosemia. Se suspendió la alimentación con leche materna, se inició leche de soya con resolución del cuadro clínico.


Jaundice is a commonly occurring problem in hospitals' neonatal units. This report describes a newborn with hypefbilirrubinaemia; the clinical picture was initially dominated by the unconjugated bilirubin fraction and later by anaemia, hepatomegaly, increased conjugated bilirubin fraction, impaired liver function, renal tubular dysfunction, cataracts and injury to CNS white matter. Various causes of direct hyperbilirrubinaemia in the newborn were ruled out. Thin-layer chromatography revealed urine-reducing substances (i.e. galactose). A marked reduction in galactose uridyl transferaseactivity was documented, thereby confirming a diagnosis of galactosaemia. Breastfeedingwas discontinued and soy milk started which led to the symptoms becoming resolved.

ABSTRACT

The central corneal thickness (CCT) is crucial to the estimation of the intraocular pressure (IOP). There are variations among different populations. The objective of the present job was to determine de CCT in a sample of Chilean population. The sample was taken at random from patients attending the office of an ophthalmologist of the Clinical Hospital of the University of Chile. The patients age ranged between 15 and 65 years. We discarded patients with IOP over 21 mm Hg, Spherical Equivalent greater than 6 diopters or with ophthalmological local treatment. The CCT was measured using ulotrasonographyc pachymeter. We enrolled 127 patients and analized 253 eyes. The CCT average was 537,70 μm 39.34 um with an standard deviation of 32.09 um. The CCT of the studied population was less than the reported in Spanish populations in USA, greater Japanese and Afro-Americans and less than Europeans and Chinese. It is important to consider the ethnic variation of the CCT in our population regarding its effect in the correction of the IO.

ABSTRACT

Introducción: Durante la pandemia por influenza A(H1N1), Chile alcanzó una de las tasas de casos más alta del mundo. Nuestro hospital recibió numerosos afectados el 2009 y 2010. Evaluamos el impacto de ventilación en posición prono (VPP) extendida, en las variables respiratorias de pacientes con SDRA grave secundario a influenza, y comparamos estos resultados con los obtenidos en otras series de VPP. Métodos: Estudio prospectivo, intervencional en UCI. Los pacientes recibieron oseltamivir y antibióticos y fueron manejados según protocolos (ventilatorio y no ventilatorio). Aquellos con criterios de SDRA grave fueron pronados hasta un índice de oxigenación <10. Se registraron parámetros de intercambio gaseoso, ventilatorios y desenlaces clínicos. Resultados: 12 pacientes con SDRA grave (edad 46+/-12 años, 7 hombres, APACHE II 17+/-6, SOFA 9+/-3) requirieron VPP, que se instauró a las 14(7-39) horas de ventilación mecánica (VM) y se mantuvo por 72(54-96) horas. Ningún paciente experimentó complicaciones mayores. La PaO2:FiO2 mejoró de 82(63-101) mmHg a 145(138-223) mmHg, (p<0.001). El tiempo en VM fue 20+/-13 días y en UCI 22+/-13 días. La mortalidad hospitalaria fue 25 por ciento y no cambió en el seguimiento de más de 8 meses. Este comportamiento con VPP fue similar al observado en otras series de SDRA grave. Conclusión: Los resultados obtenidos sugieren que la VPP resultó segura y se asoció a mejoría del intercambio gaseoso en pacientes con SDRA por influenza A(H1N1). Aunque el número reducido de pacientes no permite sacar mayores conclusiones, la VPP extendida podría ser de utilidad en los casos más graves causados por esta nueva influenza.


Introduction: During pandemic for influenza A(H1N1), Chile achieved one of the highest rates of infection worldwide. On 2009 and 2010, our hospital received a large number of infected patients. We evaluated the impact of extended prone position ventilation (PPV) on respiratory variables from severe ARDS patients secondary to this influenza. We also compared these results with those obtained with PPV in other series. Methods: Prospective, interventional study, performed in a mixed-ICU. Patients received oseltamivir and antibiotics, and were treated according to protocols (ventilatory and non-ventilatory). Severe ARDS patients were proned until oxygenation index was < 10. Oxygen exchange, ventilatory parameters and clinical outcomes were registered. Results: 12 severe ARDS patients (46+/-12 y.o., 7 men, APACHE II 17+/-6, SOFA 9+/-3) required PPV, which was started 14(7-39) hours after mechanical ventilation (MV) initiation, and it was maintained for 72(54-96) straight hours. No major complication was described. Three patients needed two periods of PPV. PaO2:FiO2 improved significantly with PPV from 82(63-101) mmHg to 145(138-223) mmHg, (p<0.001). Time on MV was 20+/-13 days, and LOS in UCI was 22+/-13 days. Hospital mortality was25 percent and remained unchanged for at least 8 month of follow-up. PPV had the same effect than in other severe ARDS series. Conclusion: Our results suggest PPV is safe and it was associated with improvement in oxygen exchange in ARDS secondary to A(H1N1) influenza. Although the small number of patients does not allow drawing any major conclusion, we believe PPV can be useful to treat severe ARDS cases due to influenza infection.

ABSTRACT

Introduction: Ocular manifestations in patients with syphilis may involve almost any of the structures of the eye. Objectives: To describe ten new cases of syphilis with eye involvement and to briefly discuss the management and therapy of such condition. Material and Methods: Ten cases were retrospectively studied over 13 years. Demographic factors, ophthalmologic examination, and laboratory tests were assessed. Results: Seven of the 10 cases were male and 3 were female. The mean age of patients was 39,7 years. Disease presentation included: panuveitis (6 patients), optic neuritis (3), retinal vasculitis (1) and Argyll-Robertson pupil (1). Cerebrospinal fluid VDRL test was positive in 6 patients and 3 patients were HIV (+). Conclusions: Syphilis is able to display diverse ophthalmologic manifestations. Not in all the cases the CSF-VDRL test was positive. Antitreponemal therapy generates a fast and effective response in the affected patients.


Introducción: Las manifestaciones oculares de los pacientes con sífilis pueden comprometer cualquiera de las estructuras del ojo. Objetivos: Describir diez nuevos casos de sífilis con compromiso ocular y realizar una breve discusión de su manejo y tratamiento. Pacientes y Métodos: Se estudiaron, de forma retrospectiva, diez casos en un período de 13 años. Se evaluaron factores demográficos, exámenes oftalmológico y de laboratorio. Resultados: De los diez casos, 7 eran hombres y 3 mujeres. El promedio de edad fue de 39,7 años. Las presentaciones fueron: panuveítis (n: 6), neuritis óptica (n: 3), vasculitis retinal (n: 1) y pupila de Argyll-Robertson (n: 1). Se obtuvo VDRL (+) en líquido cefalorraquídeo en 6 pacientes y serología para VIH (+) en 3 pacientes. Conclusiones: La sífilis puede producir variadas manifestaciones oftalmológicas. No en todos los casos el VDRL resultó positivo en el LCR. El tratamiento anti-treponémico produce una rápida y efectiva respuesta en los pacientes afectados.

ABSTRACT

En la literatura no existe suficiente evidencia que soporte la asociación de un antiviral al corticoide sistémico; sin embargo, su uso es frecuente en la práctica clínica justificada por la posible etiología viral. Objetivo: Describir la frecuencia de recuperación completa de la parálisis facial periférica idiopáticaen los pacientes que reciben prednisolona o prednisolona/aciclovir.Métodos: Se realizó un estudio de cohorte histórica identificando los casos de parálisis facial periférica. Resultados: Se reportan 106 casos, 59 mujeres (55,7%) y 47 hombres (44,3%), con edad promedio 36.9 años (DE16.7). Al ingreso el 47,2% de los pacientes presentaron parálisis grado III. Recibieron prednisolona 32 pacientes (30,2%) y prednisolona-aciclovir 74 (69,8%). La recuperación completa (House Brackman I) con prednisolona se documentó en 23 (71,9%) y 52 (70,2%) pacientes tratados con prednisolona-aciclovir. El seguimiento mediano fue 39 días. En ambos grupos lafrecuencia de mejoría fue mayor en quienes ingresaron con grados II y III de parálisis. Conclusión: La tasa de mejoría reportada es superior a la descrita con el uso de placebo pero está por debajo de lo esperado para el uso de prednisolona a 3 meses. La frecuencia de recuperación completa fue similar con prednisolona y prednisolona-aciclovir.


There is not enough evidence in the literature available that supports the addition of an anti viral to the systemic corticoid. However, it is frequently used in clinical practice where it is justified by the probable viral etiology. Objective: To describe the full recovery frequency of idiopathic peripheral facial paralysis in patients to whom prednisolone or prednisolone / acyclovir is given. Methods: A historical cohort study was conducted and the cases of peripheral facial paralysis were identified. Results: 106 cases were reported, 59 women (55,7%) and 47 men (44,3%), with an average age of 36.9 years of age (DE 16.7). 47,2% of the patients showed paralysis of the III degree upon admission. 32 of the patients (30,2%) were administered prednisolone and 74 (69,8%) were given prednisolone / acyclovir. Full recovery (House Brackman I) with prednisolone was documented in 23 (71,9%) and 52(70,2%) of the patients that had been treated with prednisolone-acyclovir. The average follow – up was 39 days. Recovery frequency was higher in both groups among the patients that were admitted to the hospital with degree II and III paralysis. Conclusion: The reported recovery rate is above the one described when using placebo but it is stillbelow the expected rate when using prednisolone for 3 months. Full recovery frequency was similar with prednisolone and with prednisolone-acyclovir.

ABSTRACT

Introduction: Eye infection is a common cause of ophtalmologic consultation. Adenovirus keratoconjunctivitis outbreaks are common worldwide but its impact and clinical characteristic in Chilean population is unkown. Objective: To describe a series of adenovirus keratoconjunctivitis cases. Patients and Method: The Índex case and contacts received medical care in the Hospital Clínico Universidad de Chile between April and August 2006. A complete ophthalmologic exam and microbiologic evaluation was performed. Results: Nine patients presented a pattern of characteristic epidemic keratoconjunctivitis. In x cases sub-corneal epithelial infiltrates were observed for a period of more than six months. Three affected patients were ophtalmologists, staff at the Hospital. In seven patients ADV was isolated all bellonging to type D genus. Conclusions: Adenovirus type D caused epidemic keratoconjunctivitis in a series of Chilean individuals. Ophthalmologist may have transmitted the virus to patients.


Introducción: La patología ocular infecciosa es frecuente en la consulta oftalmológica, especialmente la conjuntivitis y queratoconjuntivitis epidémica (QCE). Brotes de esta patología son causados por adenovirus (ADV) en el extranjero; en Chile se desconoce su impacto y características. Objetivos: Describir una serie de casos de queratonconjuntivitis epidémica por adenovirus. Material y Pacientes: Al caso índice y los contactos de una serie de casos de QCE por ADV que consultaron en el Hospital Clínico de la Universidad de Chile, entre abril y agosto de 2006, se les realizó examen oftalmológico completo y estudio de ADV por aislamiento viral, detección de antígenos y de genoma viral. Se estableció el género de ADV mediante reacción de polimerasa en cadena. Resultados: Los 9 pacientes infectados presentaron QCE característica. En algunos casos se observaron infiltrados sub-epiteliales corneales que se extendieron por más de seis meses. Tres pacientes eran médicos oftalmólogos. En 7 de los 9 pacientes examinados se aisló ADV; todos del género D. Conclusiones: En Chile, la QCE puede ser causada por el subgénero tipo D. El médico oftalmólogo es un potencial vector en la transmisión de ADV en un brote de QCE, por lo que es fundamental que sea considerado en las estrategias de prevención de esta patología.

ABSTRACT

There has been growing evidence through epidemiological and clinical studies of the importance to implement strategies for a comprehensive approach to the reduction of cardiovascular risk clustersboth in individuals and populations. Recent trials have documented the limitations and perils of prioritizing target levels of isolated risk factors over the approach to achieve them. A more inclusive strategy for cardiovascular riskcontrol has a special relevance today in view of the threat represented by the worldwide obesity epidemic.

ABSTRACT

Introducción: En el hospital el contacto directo es el mecanismo de transmisión más frecuente; así que para reducir el contagio es necesario el lavado de manos y el seguimiento de las precauciones estándar en el cuidado del paciente. Objetivo: Observar la frecuencia de uso del lavado de manos y las precauciones estándar en el personal de salud. Metodología: es un estudio exploratorio transversal, con muestra no probabilística por conveniencia formada por 50 miembros del equipo de salud de un hospital pediátrico del DF; a quienes se les aplicó el instrumento con escala tipo Likert "Guía de Observación sobre el Lavado de manos y precauciones estandar". Las prácticas de medidas de asepsia, solo en aquellos que tenían contacto directo con el paciente. Resultados: se encontró que la frecuencia de lavado de manos de 20 segundos o más fue de tan solo el 4%. También se encontró que la NOM-EM-002- SSA2-2003 no fue llevada a cabo. Estas situaciones ponen en riesgo de infección tanto a los pacientes como al personal de la salud. Discusión y conclusiones: El lavado de manos y la práctica de las precauciones estándar, protegen de los agentes infecciosos tanto a los pacientes como al personal de la salud y por tanto deben ser base de toda terapéutica intrahospitalaria.


Introduction: Within hospital environments direct contact i8s the most frequent infection transmission form; therefore, in order to reduce infections it is necessary to wash hands frequently and the follow the corresponding standard preventive measures. Objective: Observer the wash one's hands frequency of use and the standard precautions in the health's personnel. Methodology: This is a basic explorer transversal study based on a non probabilistic sample of 50 members from a D:F: Pediatric Hopspital. Used the Likert- scales instrument "Hand wash and standard preventive measures observation guide" and cleanliness practices were specifically assessed on those with close contact with patients. Results: It found that the frequency of hand washing lasting 20 seconds or more turned out to be only 4% . We also found that the health norm NOM-EM-002-SSA2- 2003was frequently underestimated. These situations place both the patients and the health staff at risk of infection. Discussion and conclusions: frequent hand washing while following the standard preventive measures protect both the patients and the health staff from infectious agents and thus must be the base of all therapeutics within hospitals.

ABSTRACT

Objetivo: Determinar la influencia de factores sociodemográficos en las manifestaciones clínicas, actividad de la enfermedad, estado funcional y calidad de vida de pacientes con artritis psoriásica (APs). Métodos: Se incluyeron 148 pacientes con APs reclutados de varios centros de reumatología de Argentina. Se determinaron factores sociodemográficos: edad, sexo, raza, nivel de educación, fuentes de ingreso personal, escala de Graffar y clases sociales. Al inicio de la enfermedad se evaluaron las siguientes variables: edad al inicio, duración de la enfermedad, manifestaciones clínicas y forma clínica de presentación. La actividad de la enfermedad fue evaluada mediante número de articulaciones activas, escala visual análoga (EVA) global del paciente y BASDAI. El estado funcional y la calidad de vida de los pacientes se determinó por medio de BASFI, ASQoL y SF-12 (Versión 1.0). Para el análisis estadístico de los datos obtenidos se utilizó test de Chi-cuadrado, test exacto de Fisher y test de Kruskal-Wallis. Resultados: De los 148 pacientes, 58,8% fueron mujeres con una edad media al inicio de la enfermedad de 53,2 ± 13,6 años y una duración media de enfermedad de 9,3 ± 8,9 años. La edad al inicio, el sexo, la raza y la escala de Graffar no estuvieron asociados con manifestaciones clínicas, actividad de la enfermedad, estado funcional y calidad de vida
