ABSTRACT

Resumen El síndrome del linfocito pasajero (PLS) es una complicación de injerto contra huésped que se presenta en el trasplante de órganos sólidos o en el trasplante de células progenitoras hematopoyéticas. Es una causa importante de hemólisis inmune después del trasplante causada por la producción de anticuerpos por parte de los clones específicos de linfocitos B viables transferidos a través del órgano del donante contra los antígenos de los glóbulos rojos del receptor. Generalmente ocurre en los trasplantes con discordancia menor ABO o Rh. Este estudio descriptivo describe el caso de un paciente de 54 años con grupo sanguíneo O/Rh(D) positivo, con cirrosis secundaria a enfermedad metabólica asociada al hígado graso (MAFLD) que fue llevado a trasplante hepático de donante O/Rh(D) negativo. A los 9 días del trasplante presentó una anemia hemolítica inmune por anticuerpos anti-D por efecto del linfocito B pasajero del donante sensibilizado. El paciente recibió medidas de soporte, transfusión de glóbulos rojos e inmunosupresión con esteroides, con lo que se logró la estabilización de los parámetros hemolíticos. En conclusión, esta es una entidad que se debe sospechar en caso de anemia hemolítica aguda en el período postrasplante.


Abstract Passenger lymphocyte syndrome (PLS) is a graft-versus-host complication in solid organ transplantation or hematopoietic stem cell transplantation. It is a major cause of immune hemolysis after transplantation caused by the production of antibodies by the specific clones of viable B lymphocytes transferred through the donor organ against the antigens of the recipient's red blood cells. It usually occurs in transplants with minor ABO or Rh mismatch. This descriptive study explains the case of a 54-year-old patient with O/Rh(D) positive blood group, with cirrhosis secondary to metabolic disease associated with fatty liver (NAFLD), who underwent liver transplantation from an O/Rh(D) negative donor. Nine days after the transplant, the patient presented with immune hemolytic anemia due to anti-D antibodies because of the transient B lymphocyte from the sensitized donor. The patient received support measures, transfusion of red blood cells, and immunosuppression with steroids, which stabilized the hemolytic parameters. In conclusion, this entity should be suspected in the case of acute hemolytic anemia in the post-transplant period.

ABSTRACT

Contexto la infección de vías urinarias (IVU), causada por adenovirus (ADV) posterior al trasplante renal, tiene el potencial de causar disfunción o pérdida del injerto. La presentación clínica es variable y el tratamiento difiere según la disponibilidad de medicamentos en el medio y la experiencia clínica. Objetivo el estudio describe las características clínicas, de laboratorio y la respuesta al tratamiento de una serie de casos de pacientes trasplantados renales con IVU por ADV en un hospital de Cali, Colombia. Metodología estudio retrospectivo que incluye a todos los pacientes adultos trasplantados con diagnóstico de IVU por ADV entre enero del 2015 hasta enero del 2021. El diagnóstico se realizó basado en la clínica, el resultado positivo de la prueba de reacción de cadena de polimerasa (PCR) y la carga viral del ADV. Resultados de 256 pacientes trasplantados, ocho presentaron diagnóstico de cistitis hemorrágica o nefritis intersticial secundaria a infección por ADV. Se presentó de forma temprana (≤ 3 meses) en el 62 % de los casos, quienes debutaron con macrohematuria asociada a piuria estéril y linfopenia. Por otra parte, se presentó alteración en la función renal en el 87,5 % de los casos y la reducción de la inmunosupresión fue el pilar fundamental en el manejo clínico. Conclusiones el reconocimiento de la infección por ADV en pacientes trasplantados renales ha ido en aumento. La sospecha clínica es clave para el diagnóstico (macrohematuria, síntomas urinarios irritativos y falla renal) y la reducción de la dosis de inmunosupresión para restaurar la función inmune puede ser suficiente en la resolución de la infección y la reversión de la disfunción renal.


Introduction Urinary tract infection (UTI) caused by adenovirus (ADV) after kidney transplantation has the potential to cause graft dysfunction or loss. The clinical presentation is variable, from an asymptomatic course to a multisystemic compromise. Treatment varies based on the availability of different medications and clinical experience. Objective The study describe the clinical, laboratory characteristics and results of a series of cases of kidney transplant patients with hemorrhagic cystitis secondary to ADV infection in a hospital in Cali, Colombia. Methods Retrospective study based on the records of patients with a diagnosis of UTI caused by ADV between January 2015 to January 2021 were included. The diagnosis was made by clinical suspicion and polymerase chain reaction (PCR) - Adenovirus DNA viral load. Results Of 256 transplant patients, eight patients had a diagnosis of hemorrhagic cystitis or interstitial nephritis secondary to ADV infection. It presented early (≤ 3 months) in 62%, who presented with macrohematuria, associated with sterile pyuria and lymphopenia. Alterations in renal function were presented in 87.5%. The reduction of immunosuppression was the fundamental pillar in the management. Conclusions The recognition of ADV infection in kidney transplant patients has been increasing. Clinical suspicion is the key for the diagnosis, with a predominance of macrohematuria, irritative urinary symptoms and kidney graft dysfunction. Reducing the dose of immunosuppression by restoring immune function may be sufficient in resolving the infection and reversing renal dysfunction.

ABSTRACT

RESUMEN Introducción: Las enfermedades cardiovasculares representan la principal causa de muerte de la población mundial. Objetivo: Identificar los factores predictores de mortalidad hospitalaria en pacientes con infarto agudo del miocardio en el Hospital General Docente "Dr. Agostinho Neto", durante el año 2017. Método: Se realizó un estudio retrospectivo analítico de tipo caso y control, en una población conformada por 90 pacientes con infarto. En el grupo caso se encontraron todos los pacientes fallecidos durante el ingreso (n=30) que cumplieron los criterios de inclusión y exclusión, mientras que el grupo control estuvo constituido por 60 pacientes que egresaron vivos, seleccionados al azar mediante un muestreo aleatorio simple. Resultados: La media de la edad fue mayor en el grupo de los casos 74,06 respecto a los controles, (p=0,021). El 86,6 % de los casos no recibió trombolisis y el 6,6 % tuvo algún criterio de reperfusión pos-estreptoquinasa (p=0,00). El 36,6 % de los casos presentó choque cardiogénico (p=0,003), ruptura cardíaca (30 %) (p=0,03), y taponamiento (23,3 %) (p=0,01). Conclusiones: Los factores predictores de mortalidad hospitalaria en pacientes con infarto agudo del miocardio son: la edad avanzada, el tiempo prolongado entre el inicio de los síntomas y la asistencia médica, la existencia de las complicaciones, tales como el choque cardiogénico, el taponamiento cardíaco y la ruptura cardíaca, así como la no administración de tratamiento trombolítico y la ausencia de reperfusión.


ABSTRACT Introduction: Cardiovascular disease is the main cause of death worldwide. Objective: To identify the predictor factors of hospital mortality in patients with acute myocardial infarction at the Hospital General Docente "Dr. Agostinho Neto" in 2017. Method: A retrospective analytical case-control study was performed in a population of 90 patients with myocardial infarction. The case-cohort study included all patients who died during admission (n=30) and met the inclusion and exclusion criteria, while the case-control study included 60 patients who were discharged alive, randomly selected by simple random sampling. Results: The mean age was higher in the case-cohort studied (74.06 years) than the case-control (p=0.021). The 86,6% of cases did not receive thrombolysis and 6.6% had some reperfusion criteria after the streptokinase (p=0.00). Cardiogenic shock (p=0.003), cardiac rupture (30%) (p=0.03), and cardiac tamponade (23.3%) (p=0.01) were present in 36.6% of cases. Conclusions: The predictor factors of hospital mortality in patients with acute myocardial infarction are as follows: age, the prolonged time between the onset of symptoms and medical attention, presence of complications such as cardiogenic shock, cardiac tamponade and cardiac rupture, as well as the non-administration of thrombolytic treatment and the absence of reperfusion.


RESUMO Introdução: As doenças cardiovasculares representam a principal causa de morte da população mundial. Objetivo: Identificar os fatores preditivos de mortalidade hospitalar em pacientes com infarto agudo do miocárdio no Hospital Geral Universitário "Dr. Agostinho Neto", durante 2017. Método: Foi realizado um estudo retrospectivo analítico caso-controle em uma população de 90 pacientes com infarto. No grupo caso, foram encontrados todos os pacientes que morreram na admissão (n=30) que atenderam aos critérios de inclusão e exclusão, enquanto o grupo controle foi composto por 60 pacientes que receberam alta com vida, selecionados aleatoriamente por amostragem aleatória simples. Resultados: A média de idade foi maior no grupo de casos 74,06 em relação aos controles (p=0,021). 86,6% dos casos não receberam trombólise e 6,6% tinham algum critério para reperfusão pós-estreptoquinase (p=0,00). 36,6% dos casos apresentaram choque cardiogênico (p=0,003), ruptura cardíaca (30%) (p=0,03) e tamponamento (23,3%) (p=0,01). Conclusões: Os fatores preditivos de mortalidade hospitalar em pacientes com infarto agudo do miocárdio são: idade avançada, longo tempo entre o início dos sintomas e o atendimento médico, a existência de complicações, como choque cardiogênico, tamponamento cardíaco e ruptura cardíaca, bem como a não administração de tratamento trombolítico e a ausência de reperfusão.

ABSTRACT

Background@#Aleutian mink disease virus (AMDV) causes major economic losses in fur-bearing animal production. The control of most AMDV outbreaks is complex due to the difficulties of establishing the source of infection based only on the available on-farm epidemiological data. In this sense, phylogenetic analysis of the strains present in a farm may help elucidate the origin of the infection and improve the control and biosecurity measures. @*Objectives@#This study had the following aims: characterize the AMDV strains from most outbreaks produced at Spanish farms between 2012–2019 at the molecular level, and assess the utility of the combined use of molecular and epidemiological data to track the possible routes of infection. @*Methods@#Thirty-seven strains from 17 farms were partially sequenced for the NS1 and VP2 genes and analyzed phylogenetically with other strains described worldwide. @*Results@#Spanish AMDV strains are clustered in four major clades that generally show a good geographical correlation, confirming that most had been established in Spain a long time ago. The combined study of phylogenetic results and epidemiological information of each farm suggests that most of the AMDV outbreaks since 2012 had been produced by within-farm reservoirs, while a few of them may have been due to the introduction of the virus through international trade. @*Conclusions@#The combination of phylogenetic inference, together with epidemiological data, helps assess the possible origin of AMDV infections in mink farms and improving the control and prevention of this disease.

ABSTRACT

Abstract Canine leishmaniasis (CanL) is a disease caused by Leishmania infantum. Serological methods are the most common diagnostic techniques used for the diagnosis of the CanL. The objective of our study was to estimate the sensitivity and specificity of one in-house ELISA kit (ELISA UNIZAR) and three commercially available serological tests (MEGACOR Diagnostik GmbH) including an immunochromatographic rapid test (FASTest LEISH®), an immunofluorescent antibody test (MegaFLUO LEISH®) and an enzyme-linked immunosorbent assay (MegaELISA LEISH®), using latent class models in a Bayesian analysis. Two hundred fifteen serum samples were included. The highest sensitivity was achieved for FASTest LEISH® (99.38%), ELISA UNIZAR (99.37%), MegaFLUO LEISH® (99.36%) followed by MegaELISA LEISH® (98.49%). The best specificity was obtained by FASTest LEISH® (98.43%), followed by ELISA UNIZAR (97.50%), whilst MegaFLUO LEISH® and MegaELISA LEISH® obtained the lower specificity (91.94% and 91.93%, respectively). The results of present study indicate that the immunochromatographic rapid test evaluated FASTest LEISH® show similar levels of sensitivity and specificity to the quantitative commercial tests. Among quantitative serological tests, sensitivity and specificity were similar considering ELISA or IFAT techniques.


Resumo A leishmaniose canina (Lcan) é uma causada pela Leishmania infantum. Os métodos sorológicos são as técnicas diagnósticas mais utilizadas para o diagnóstico da leishmaniose canina. O objetivo do nosso estudo foi estimar a sensibilidade e a especificidade de um kit ELISA interno (ELISA UNIZAR) e de três testes sorológicos disponíveis comercialmente, feitos pelo mesmo fabricante (MEGACOR Diagnostik GmbH), incluindo um teste rápido imunocromatográfico (FASTest LEISH®), um teste de anticorpos imunofluorescentes (Megafluo LEISH®) e um ensaio de imunoabsorção enzimática (Megaelisa LEISH®), utilizando-se modelos de classe latentes numa análise bayesiana. Foram incluídas duzentas e quinze amostras de soro. A maior sensibilidade foi alcançada para Fastest LEISH® (99,38%), ELISA UNIZAR (99,37%), Megafluo LEISH® (99,36%) seguida por Megaelisa LEISH® (98,49%). A melhor especificidade foi obtida por FASTest LEISH® (98,43%), seguida por ELISA UNIZAR (97,50%), enquanto Megafluo LEISH® e Megaelisa LEISH® obtiveram a menor especificidade (91,94% e 91,93%, respectivamente). Os resultados do presente estudo indicam que o teste rápido imunocromatográfico, avaliado por FASTest LEISH® mostra níveis similares de sensibilidade e especificidade aos testes comerciais quantitativos incluídos. Entre os testes sorológicos quantitativos, a sensibilidade e a especificidade foram semelhantes, considerando-se as técnicas de ELISA ou IFI.

ABSTRACT

Hemangiopericytoma is a tumor derivated from the mesenchymal cells that surround the capillary of blood vessels. It has a several anatomic localization and clinic scenarios, it´s presentation with a media in the 6th decade; an early diagnostic and treatment represents a better clinic scenario for the patient. The next article presents a case report of a 51 years old man with a tumor localized in the sacrococcygeal space, with big dimensions that limited his daily activities without other symptomatology, image studies with no evidence of distant progression. Surgical resection was performed, removing mass depending from mayor and minor gluteus, achieving an immediate reconstruction with a satisfactory aesthetic and functional result. The authors presented this rare case due to the lack of published information and how it can be treated to achieve good results.

ABSTRACT

Los trastornos del espectro autista (TEA) engloban a un grupo heterogéneo de trastornos del neurodesarrollo que tienen en común la presencia de problemas para la interacción/comunicación social y la tendencia a mostrar intereses restringidos o conductas repetitivas. Diversos estudios epidemiológicos realizados en diferentes países en los últimos años han mostrado de forma consistente dos características: el incremento progresivo en la prevalencia de los TEA a nivel mundial y la existencia de una gran variabilidad geográfica entre territorios y dentro de un mismo territorio. En el presente artículo analizamos los datos de prevalencia más recientemente publicados en EE.UU. y en diversos países de Europa (incluyendo España), que muestran tasas de prevalencia muy variables, con un rango que abarca desde 1/59 niños con trastornos del espectro autista en EE. UU., hasta 1/806 en Portugal. En un segundo tiempo describimos brevemente algunas de las principales hipótesis que intentan explicar esta variabilidad.


Autism spectrum disorders are a heterogeneous group of disorders that share the presence of two core symptoms: problems in social interaction / communication and the tendency to present restricted interests and repetitive behavior. Over the last years, several epidemiologic studies have been published by different authors in diverse countries, having all of them shown two common characteristics: a global increase in the prevalence rates of autism spectrum disorders, and the existence of a great geographical variability no only between geographical areas, but also within the same geographical areas. At the present manuscript, we analyze some of the most recent prevalence data published in USA and some European countries (including Spain). All of them show different prevalence rates, ranging from 1/59 children with autism spectrum disorders in the USA to 1/806 in Portugal. In a second part, we briefly describe some of the current scientific hypotheses that try to explain this variability.

ABSTRACT

Resumen Introducción y objetivos: Dronedarona y flecainida son antiarrítmicos de primera elección para reducir recurrencias de fibrilación auricular (FA), sin existir estudios que los comparen entre sí. Nuestro objetivo es comparar la eficacia en cuanto a prevención de recurrencias y seguridad de ambos fármacos. Métodos: Estudio retrospectivo en el que se incluyeron 123 pacientes de forma consecutiva en tratamiento con flecainida o dronedarona desde octubre de 2010 hasta febrero de 2013 por FA paroxística (76.4%) y FA persistente (23.6%). Se realizó cardioversión eléctrica en un 7.3% de los pacientes y farmacológica en un 16.3%. La mediana (rango intercuartílico) de seguimiento fue de 301 días (92-474), con una media de 2.8 revisiones por paciente. Se realizó análisis de tiempo hasta el primer evento mediante Kaplan-Meier y regresión de Cox ajustada por un índice de propensión. Resultados: De entre los 123 sujetos incluidos con FA, 71 fueron tratados con flecainida y 52 con dronedarona. Durante el seguimiento se registraron 36 recurrencias y 20 efectos adversos. Se documentaron un 36.6% de recurrencias en los pacientes tratados con flecainida en comparación con un 21% en los tratados con dronedarona (p = 0.073). En el análisis multivariante, dronedarona se mostró al menos tan eficaz como flecainida para prevenir recurrencias de FA (HR: 0.53, IC 95%: 0.20-1.44, p = 0.221) y demostró un perfil de seguridad comparable al de flecainida (HR: 0.68, IC 95%: 0.18-2.53, p = 0.566). Conclusiones: Según nuestra experiencia, dronedarona resulta al menos tan eficaz como flecainida para el mantenimiento de ritmo sinusal, con un buen perfil de tolerabilidad, a pesar de pautarse en pacientes con un perfil clínico más desfavorable.


Abstract Introduction and objectives: Dronedarone and flecainide are the first pharmacological choice to reduce recurrence of atrial fibrillation (AF); however, there are no studies comparing them. A study was performed to compare the efficacy in terms of recurrence of AF and safety of both drugs. Methods: A retrospective cohort study was conducted that included 123 consecutive patients treated with flecainide or dronedarone due to paroxysmal AF (76.4%) or persistent AF (23.6%), from October 2010 to February 2013. Electrical cardioversion was performed in 7.3% of patients and pharmacological cardioversion in 16.3%. The median (interquartile range) follow-up was 301 days (92-474) with a mean of 2.8 reviews per patient. Time to first event analysis was performed using Kaplan-Meier and Cox regression, adjusted for propensity score. Results: Of the 123 consecutive patients with AF included, 71 were on dronedarone and 52 on flecainide. During the follow-up, there were 36 AF recurrences and 20 safety events. There were recurrences in 36.6% of patients treated with flecainide, compared with 21% of those receiving dronedarone (P = .073). Dronedarone showed to be at least as effective as flecainide in preven- ting recurrence of atrial fibrillation (HR: 0.53, 95% CI: 0.20-1.44, P = .221), and demonstrated an acceptable safety profile when compared with flecainide (HR: 0.68, 95% CI: 0.18-2.53, P = .566). Conclusions: In our experience, dronedarone has been at least as effective and safe as flecainide, despite it was most frequently prescribed in patients with worse baseline risk profile.

ABSTRACT

El objetivo de este estudio fue evaluar un modelo que relaciona interés, compromiso y rendimiento. El estudio evaluó tres modalidades de interés situacional (activado, mantenido-afecto y mantenido-valor), el compromiso conductual, el desapego conductual y el rendimiento en clase de Lengua Española. Estas variables se evaluaron en el aula a lo largo de un período de nueve meses en una muestra de 565 alumnos españoles de Educación Secundaria Obligatoria (ESO), con edades comprendidas entre 12 y 17 años (Media = 13.78 años; DE = 1.14). Una serie de modelos de ecuaciones estructurales reveló que las tres modalidades del interés situacional predijeron significativamente el compromiso, el desapego y el rendimiento; compromiso y desapego predijeron el rendimiento; como se había hipotetizado, compromiso y desapego mediaron los efectos del interés situacional sobre el rendimiento académico. Para concluir, se discuten los resultados y sus implicaciones para la teoría del interés y para los programas de intervención educativa.


The purpose of this study was to test a model linking interest, engagement, and performance. The study assessed three types of situational interest (triggered, maintained-feeling, and maintained-value), behavioral engagement, behavioral disaffection, and performance in Spanish language classes. These variables were assessed in the classroom over a nine-month period on a sample of 565 Spanish secondary students aged 12 to 17 years (Mean age = 13.78 years; SD = 1.14). A series of structural equation models revealed that the three types of situational interest significantly predicted engagement, disaffection, and performance; engagement and disaffection also predicted performance; as hypothesized, engagement and disaffection mediated the effects of situational interest on academic performance. To conclude, the implications of these findings are discussed in the light of current theory of interest and educational intervention programmes.

ABSTRACT

Immunostimulants are susbstances that stimuli the response of effector cells to activate the immune response such as antigen uptake, cytokine release or antibody response. These substances can increase resistence to infection by different types of microorganisms, reducing dependence of antibiotics used in livestock animals. Recent reports have demonstrated the positive effect of Propionibacterium acnes (P. acnes) to control animal diseases. In this study, we evaluated the effect of the non-specific immunostimulant P. acnes on immunological functions and growth performance in goat kids. Twenty five goat kids served as control group (A) and another 25 animals received P. acnes being the experimental group (B). Kids were challenged with ovalbumin (OVA) to assess humoral immunity. To assess in vivo cell immunity, delayed type hypersensitivity (DTH) test with phytohemagglutinin (PHA) was used, clinical signs and body weight were recorded each week until 9 weeks of age when the experiment ended. Blood samples were obtained to analyze serum proteins fractions and anti-OVA specific antibodies. No clinical signs of disease and no differences (p>0.05) on body weight between groups were recorded (7.32±0.81 kg in group A, 7.13±0.65 kg in group B). Goat kids from group B had more total protein (59.8±5g/l) and albumin levels (32.8±3.3g/l) than goat kids from group A (56.6±5.7 g/l, 29.6±3.9 g/l respectively) (p<0.05). DTH response in goat kids from group B on day 42 was higher (p<0.05) than group A. At day 63, goat kids from group receiving P. acnes had higher percentage (85.4) of anti-OVA IgM titers (p<0.05) than control group (57.7). In conclusion, the results showed that oral administration of P. acnes to goat kids improved some aspects of the immune system of the animals and it could be used to control goat diseases.

ABSTRACT

El objetivo del presente trabajo es examinar los conceptos y fundamentos sobre Salud Pública Internacional de mayor aceptación universal, lo que puede aportar una dimensión utilitaria, pues su aplicación en un país determinado puede contribuir a que su sistema de salud se ajuste mejor a los problemas concretos de salud que afectan a su sociedad y a las influencias de la coyuntura internacional sobre estos problemas. Se encontró que es impreciso el inicio del uso del término y que no existe un concepto universalmente aceptado sobre salud pública internacional, de hecho, algunos autores usan el término Salud Global. Para su análisis la Salud Pública Internacional debe dividirse en dos polos: la dimensión internacional de la salud y la salud como asunto internacional, los que conforman una intrincada relación dialéctica, pero es la superposición de estos dos ámbitos lo que determina el resultado total. La salud pública internacional se fundamenta en determinada ideología y al aceptar que es un recorte de las relaciones internacionales, corresponderá a cada Estado determinar el alcance y la aplicación de este concepto en su territorio. Se apreció que los aspectos de la Salud Pública Internacionalno están incluidos de forma sistemática dentro de los campos de estudio de las escuelas de salud pública en la región, por lo que se sugiere desarrollar eventos de carácter regional que permitan lograr consenso en una definición coherente sobre el término salud pública internacionaly su marco conceptual.


The objective of this paper is to analyze the most universally accepted concepts and fundamentals on International Public Health. This can provide one utilitarian dimension since their application in a particular country could contribute to better adjust the public health system to the particularities of the health problems affecting its society and to the influence of the international situation over these problems. It was found that data about the use of this term for the first time was inaccurate and that there was not one universally accepted concept on International Public Health; as a matter of fact, some authors prefer the term Global Health. For the analysis, international health should be divided into two poles: international dimension of health on one hand and health as international issue on the other; both make up an intrincate dialectical relation but the overlapping of these two aspects determines the final result. international public health is based on certain ideology and once accepted as a part cut out from the international relations, it is up to every state to determine the scope and range of application of this concept in its territory. It was observed that the International Public Health aspects are not systematically included in the curricula of the schools of public health in the region; therefore, it is suggested that regional events be held in order to reach consensus with respect to a coherent definition on the term international public health and its conceptual framework.

ABSTRACT

El Sildenafil es un fármaco de comprobada actividad terapéutica en la disfunción eréctil; se encuentra disponible bajo la forma farmacéutica de tabletas de administración oral. En la actualidad se está formulando magistralmente en forma de so lución oral a una concentración de 1mg/ml, para la hipertensión pulmonar (HP), por lo que se ha planteado realizar un estudio de la estabilidad en tres condiciones: ambientales (25±-2 ºC), de refrigeración (5±3 ºC) y exageradas de almacenamiento (40 ºC ± 2 ºC). Los parámetros evaluados fueron apariencia, limpidez, densidad, pH y contenido de sildenafil. El método analítico empleado fue cromatografía líquida de alta resolución (HPLC) de fase reversa. La apariencia, los valores de pH y densidad de las soluciones obtenidas se mostraron sin cambios significativos, en las diferentes muestras y condiciones de estudio. En cuanto a los resultados del contenido inicial de sildenafil se obtuvo aproximadamente el 75% en peso al formular la solución, partiendo del comprimido. Cabe señalar que se observó discrepancia en los valores de concentración del sildenafil obtenidos en los diferentes tiempos y condiciones; resultados éstos de esperarse por tratarse de una formulación magistral que parte de comprimidos de diferentes casas comerciales, por lo que este estudio permitió sugerir que la formulación magistral se reformule a la forma farmacéutica de suspensión, para garantizar el contenido de todo el principio activo en la misma.


Sildenafil is a drug with proven therapeutic activity in erectile dysfunction is available under the pharmaceutical form of tablets for oral administration. It is currently being de veloped skillfully in an oral solution at a concentration of 1mg/ml, for pulmonary hypertension (pH), as has been planned to perform a study of stability in three conditions: environmental (25 ± 2 ºC), refrigeration (5 ± 3 ºC) and exaggerated storage (40 °C ± 2 ºC). The parameters evaluated were appearance, clarity, density, pH and content of sildenafil. The analytical method used was high performance liquid chromatography (HPLC) reverse phase. The appearance, pH and density of the solutions were no significant changes in the different samples and study conditions. As for the results of the initial content of sildenafil was obtained about 75% by weight in for mulating the solution, based on the tablet. It should be noted that there was discrepancy in the values of concentration of sildenafil obtained at different times and conditions, results they expected because it is a masterly formulation of tablets of different business houses, so this study suggest that the wording allowed masterful be reformulated to the pharmaceutical form of suspension, to ensure the contents of the entire active.

ABSTRACT

Objective To evaluate the usefulness of positron emission tomography with 2-[18F]fluoro-2-deoxy-D-glucose (FDG-PET) in the follow-up of endometrial cancer patients with suspicion of recurrence due to elevated serum tumour markers and suggestive conventional imaging findings. Material and methods A retrospective review was conducted of 17 FDG-PET studies performed in 11 patients with a previous diagnosis of endometrial cancer (6 patients underwent 2 studies) between April 2002 and October 2005. Mean age of patients was 63.4 yrs (range, 52-69 yrs), and mean time since diagnosis was 56 months (range, 11 months - 12 yrs). Initially, 7 patients were in stage I, 3 in stage III, and 1 in stage IV (FIGO classification). Histologically, they corresponded to 8 endometrioid and 3 non-endometrioid cancers. Results FDG-PET showed infradiaphragmatic uptake in three patients and disseminated disease in seven; findings were negative in one patient. Computed tomography (CT, n=7) or magnetic resonance (MRI, n=7) images revealed infradiaphragmatic lesions in five patients and visceral lesions in two. All patients showed elevated serum tumour markers (CA125, n=9; CA19.9, n=2; CA15.3, n=2). FDG-PET results modified the information provided by conventional imaging techniques in seven patients and provided no additional information in the remaining four. There was histological confirmation of lesions in two patients. Nine patients were clinically followed up, including imaging studies (mean follow-up, 8.7 months; range, 3-20 months).

ABSTRACT

En este trabajo se coteja la interacción genotipo × prácticas de manejo sobre el índice de cosecha (IC) en 6 experimentos de campo conducidos bajo riego en el sureste de México entre 1977 y 1999. Se cuestiona la validez de utilizar el IC como constante en híbridos modernos de maíz para modelar su crecimiento a partir de algunos modelos dinámicos modulares, los cuales son aditivos e ignoran las interacciones. El diseño fue en parcelas divididas con dos repeticiones, en el que las parcelas grandes se asignaron a 25 y 27 tratamientos de un compuesto central rotatorio para N, P, K, densidad de población y fecha de siembra. Las parcelas chicas fueron asignadas a 3, 4 o 6 híbridos de maíz, todos con desempeño agronómico similar pero de diferente origen genético. Se ajustó un modelo inaditivo cuadrático al IC por regresión, para manejo y genotipo, este último mediante variables mudas. También se ajustó un modelo aditivo cuadrático para el manejo que ignoró al genotipo. Los resultados evidencian que la interacción genotipo x manejo se manifiesta en diferentes efectos lineales, curvaturas e interacciones entre híbridos, que son cambiantes entre localidades. Los IC, calculados con los tratamientos óptimos económicos, variaron entre 0,32 para H-515 y 0,60 para el Híbrido Hemoc. El modelo inaditivo mejoró el coeficiente de determinación (R2) para IC entre 14 y 47 por ciento en relación al modelo aditivo

ABSTRACT

Es un trabajo de recopilación y condensación de los cambios fisio-patológicos que pueden presentarse en la mujer durante el período de la gestación. Teniéndolos en mente, nos explicaremos más fácilmente, el comportamiento peculiar de muchas entidades clínicas cuando éstas coinciden con el embarazo y así podremos reconocer de inmediato las alteraciones verdaderas de los cambios fisiológicos, además de aplicar con mayor precisión clínica nuestros procedimientos diagnósticos. Recordaremos además que será el ultrasonido, el procedimiento de elección por sus múltiples bondades, no sólo para el estudio del producto durante la gestación, sino también para abordar la gran mayoría de los retos diagnósticos que se presentan en la mujer embarazada.Siendo ésta la continuación del tema, se manejan aquí problemas del sistema urinario y gastrointestinal coincidentes con el embarazo, así como la diabetes, la enfermedad tiroidea y finalmente infecciones y gestación.

ABSTRACT

Los autores valoran la eficacia del Ultrasonido para el diagnóstico y etapificación de lesiones del manguito rotador. El estudio se llevó cabo en forma prospectiva y longitudinal, en pacientes con diagnóstico de hombro doloroso, en quienes realizaron un examen pasivo y lo compararon con el hombro contralateral. Se estudiaron 42 pacientes, en 29 de los cuales se comparó el resultado con el de la cirugía y en 24 con la Resonancia Magnética. Las lesiones se clasificaron de acuerdo a los criterios de Wiener y Seitz, la que permite el conocimiento de la extensión del daño y correlacionarlo con el encontrado en la cirugía. Los resultados de Ultrasonido concordaron con los de la cirugía en 28/29 pacientes, obteniendo valores de significancia 0.0001, lo que demuestra que el ultrasonido es un método confiable y seguro para el abordaje del paciente con hombro doloroso
