ABSTRACT

Resumen El tumor miofibroblástico inflamatorio (TMI) es una patología muy poco frecuente. Los TMI localizados en laringe pueden ocasionar disfonía o sensación de cuerpo extraño. El diagnóstico se realiza a través de pruebas de imagen y visualización directa con obtención de muestras para estudio histopatológico. Presentamos el caso de una mujer de 43 años, con antecedentes personales de carcinoma indiferenciado de nasofaringe, tratado con radioterapia y quimioterapia, que acude a revisiones periódicas en consulta de otorrinolaringología. Se objetiva por nasofibroscopia una lesión rugosa en cuerda vocal izquierda. Se realiza biopsia con fibroscopio de canal, compatible con tumoración fusocelular atípica, con áreas celulares y mixoides, sospechosa de malignidad, con necesidad de completar estudio inmunohistoquímico. En comité de tumores de cabeza y cuello se decide cirugía programada (laringectomía supracricoidea con cricohioidoepiglotopexia) y posterior tratamiento adyuvante con quimioterapia y/o radioterapia, según resultados del estudio histopatológico. Como conclusión, el TMI es una patología que se encuentra predominantemente en el pulmón, siendo rara la afectación laríngea. Su pronóstico es favorable y el diagnóstico histopatológico es de vital importancia. El diagnóstico correcto va seguido de una escisión local amplia para prevenir la recurrencia, sin embargo, el tratamiento debe adaptarse a la ubicación del tumor y al estado del paciente.


Abstract Inflammatory myofibroblastic tumor (IMT) is a very rare pathology. IMTs located in the larynx can cause dysphonia or foreign body sensation. The diagnosis is made through imaging tests and direct visualization and confirmation with samples for histopathological study. We present the case of a 43-year-old woman with a personal history of undifferentiated carcinoma of the nasopharynx treated with radiotherapy and chemotherapy, who attended periodic check-ups in an otolaryngology clinic. A rough granulomatous lesion was observed by nasofibrolaryngoscopy in the left vocal cord. A canal fibroscope biopsy is performed, compatible with an atypical spindle cell tumor, with cellular and myxoid areas, suspicious of malignancy, requiring an immunohistochemical study to be completed. The head and neck tumor committee decides on scheduled surgery (supracricoid laryngectomy with cricohyoidoepiglottopexy) and subsequent adjuvant treatment with chemotherapy and/or radiotherapy, according to the results of the histopathological study. As a conclusion finally, the IMT is a pathology found predominantly in the lung, laryngeal involvement being rare. Its prognosis is favorable and the histopathological diagnosis is of vital importance to be able to be differentiated from other malignant neoplasms. The correct diagnosis is followed by a wide local excision to prevent recurrence, however, treatment must be tailored to the location of the tumor and the condition of the patient.

ABSTRACT

Resumen El melanoma mucoso primario (MM) de la cavidad nasal y los senos paranasales sigue siendo un tumor maligno poco frecuente. El pico de incidencia se sitúa entre 50 y 60 años, siendo la epistaxis y la obstrucción nasal unilateral los síntomas más frecuentes. La resección quirúrgica es el tratamiento primario con radioterapia y quimioterapia adyuvante si es necesario, el pronóstico depende de la extensión. Presentamos el caso de una paciente mujer de 81 años con hemoptisis y halitosis de un año de evolución. La nasofibrolaringoscopia mostró una lesión parduzca, excrecente, irregular y friable, en el borde derecho del rodete tubárico derecho. El resultado histopatológico fue MM nasofaríngeo. Perfil inmunohistoquímico: S100 +, MelanA +, HMB45 +, SOX10 +, AE1AE3 negativo. El PET-CT mostró una hipercaptación a nivel del rodete tubárico derecho, sin evidencia de adenopatías o metástasis a distancia. Se realizó la resección tumoral completa mediante abordaje endoscópico. El Comité de Oncología del Melanoma decidió que no era necesario un tratamiento adyuvante debido a la resección completa de la lesión y considerando la edad y el deterioro cognitivo de la paciente.


Abstract Primary mucous melanoma (MM) of the nasal cavity and paranasal sinuses remains a rare malignancy. The peak of incidence is between 50 and 60 years old, being epistaxis and unilateral nasal obstruction the most frequent symptoms. Surgical resection is the primary treatment with radiotherapy and adjuvant chemotherapy if necessary, the prognosis depends on the spreading. We present the case of an 81-year-old female patient attending for hemoptysis and halitosis of a year of evolution. The nasofibrolaryngoscopy showed a brownish, excrescent, irregular and friable lesion, outgrowth of the right tube rim. Histopathology result was nasopharyngeal MM. Immunohistochemical profile: S100 +, MelanA +, HMB45 +, SOX10 +, AE1AE3 negative. PET-CT showed a hypercaptation at the level of the right tube rim, without evidence of adenopathies or distant metastases. Complete tumor resection was performed by endoscopic surgery. Melanoma Oncology Committee decided no need of adjuvant therapy due to the complete resection of the lesion and considering the age and cognitive deterioration of the patient.

ABSTRACT

Resumen Debido al uso frecuente del triclabendazol (TCBZ) por parte de los productores, sumado al reporte reciente de resistencia de Fasciolahepatica al fármaco detectada en rodeos y majadas de Neuquén, se llevó a cabo el presente trabajo con el objetivo de evaluar la eficacia del TCBZ como fasciolicida en caprinos bajo un sistema de producción trashumante del norte de la provincia de Neuquén, Argentina. La eficacia se evaluó mediante un test de reducción de conteo de huevos de F. hepatica en caprinos Criollo Neuquino parasitados naturalmente. Se utilizaron dos grupos de animales: un Grupo Control (n: 10) que no recibió tratamiento y un Grupo Tratado (n: 10) al que se le administró TCBZ al 10% (Biofasiolex T10-Biogénesis Bagó ®) vía oral a dosis de 10 mg/kg PV. Al día 0 y 21 post tratamiento, se tomaron muestras de materia fecal para análisis coproparasitológicos. Se evidenció una reducción del conteo de huevos de F. hepatica del 100%, indicando el mantenimiento de la eficacia del fasciolicida en los caprinos evaluados. Se discuten los alcances del uso del test de reducción de conteo de huevos en zonas con producción trashumante del ganado.


Abstract Because of the frequent use of triclabendazole TCBZ by farmers and the recent reports of Fasciola hepatica resistance to this drug in herds and flocks from Neuquén, we carried out this study with the aim to evaluate the efficacy of TCBZ as fasciolicide in goats under a transhumance system from northern of Neuquén, Argentina. A fecal egg count reduction test (FECRT) was performed on Creale Neuquino goats naturally parasitized with F. hepatica. Twenty goats were divided into two groups: A control group (n: 10) which was left untreated, and a treatment group (n: 10) that was dosed orally with TCBZ 10% (Biofasiolex T10-Biogénesis Bagó ®). On Day 0 and Day 21 post-treatment, fecal samples were taken and analyzed by coproscopical examination. According to the FECRT, drug efficacy was 100 % and confirms that TCBZ maintains its efficacy against F. hepatica on goats. The usefulness of the FECRT in these zones under transhumance livestock production is discussed.

ABSTRACT

Resumen El presente trabajo evaluó la relación entre la eficacia y la farmacocinética de dos formulaciones comerciales inyectables de ivermectina (IVM) en ovinos merino adultos artificialmente infestados con Psoroptes ovis. Los animales fueron tratados por vía subcutánea con IVM 1 % en dos dosis con un intervalo de aplicación de 7 días, (0.2 mg/kg) o con una única dosis de IVM 3.15%, (1.05 mg/kg). Se realizaron conteos semanales de ácaros vivos mediante raspajes de piel entre el día 0 y 28 post-tratamiento para determinar la eficacia de los tratamientos, y se tomaron muestras de sangre para medir las concentraciones de IVM en plasma. Se observó una disminución significativa en los conteos de ácaros a partir del día 14 post-tratamiento, sin embargo, se encontraron ácaros vivos en todos los muestreos para ambos grupos. En el Grupo IVM 1%, la máxima eficacia se observó el día 28 post tratamiento (93.3%), mientras que en el Grupo IVM 3,15% este registro se obtuvo el día 21 (95.9%). Mayores concentraciones de IVM fueron observadas en los animales tratados con la formulación 3.15 %. La falla para obtener una cura parasitológica tras el tratamiento con ambas formulaciones de IVM puede ser indicativo de la presencia de ácaros resistentes a este principio activo.


Abstract The current work evaluated the relationship between efficacy and pharmacokinetics of two commercial injectable formulations of ivermectin (IVM) in adult merino sheep artificially infested with Psoroptes ovis. Animals were treated subcutaneously with IVM 1% formulation (two doses on days 0 and 7) at 0.2 mg / kg or with a single dose of IVM 3.15% preparation at 1.05 mg / kg. Live mites were counted weekly by performing skin scrapings between days 0 and 28 post-treatment to determine the efficacy of each IVM formulation. Blood samples were taken up to 35 days post-treatment to measure IVM plasma concentrations. A significant decrease in mite counts was observed from day 14 post-treatment. However, live mites were found in all samples for both groups throughout the entire trial. After IVM 1% administration, the highest effcacy was observed on day 28 (93.3% whereas in the IVM 3,15% group was obtained on day 21 post treatment (95.9%). Higher IVM plasma concentrations were observed in animals treated with the IVM 3.15% formulation. Failure to obtain a parasitological cure after treatment with both IVM formulations may reflect the presence of resistant mites to this drug.

ABSTRACT

Respiratory rehabilitation improves physical capacity and quality of life in COPD patients as it has been previously reported. In Chile there are few and unpublished experiences on respiratory rehabilitation programs (RRP) implemented in primary health care (PHC). Our aim was to evaluate RRP outcome in COPD patients carried out in a rural PHC center. Methods: A prospective descriptive study of RRP in a PHC center implemented in Talagante (a village located 40 km from Santiago). COPD patients were enrolled in the study from July 2012 to May 2014. Patients having the inclusion criteria were admitted to a 12 weeks-long RPP This program included a 90 minute-long sessions of aerobic training (walking), strength training of upper and lower limbs (dumbbell, ankle support and elastic bands) and respiratory muscle training (threshold valve), twice a week. Quality of life, strength of trained muscles, six-minutes walking test (TM6), BODE index and dyspnea index, were measured before and after completing RRP Results were expressed as mean ± SD. Results: Out of 79 patients initially assessed, 54 were admitted to the RRP and 39 patients completed the program and were included in the analysis. Their mean age was 67.3 ± 8.5 years, 64% were female. In average BMI was 26.97 ± 4.3 kg/m², and FEVi was 1.17 ± 0.57 liters. We demonstrated a statistically significant improvement after RRP in 6-minute walk test (445.9 ± 77.9 m versus 498.2 ± 82.8 m, p < 0.001); Saint George’s Respiratory Questionnaire score (45.1 ± 16.1 versus 18.5 ± 11.5, p < 0.0001), PIMax (48.95 ± 18.8 versus 57.2 ± 19.4 cm H2O, p < 0.0001), BODE index (2.76 ± 1.37 versus 1.53 ± 1.0, p < 0.0001), and mMRC dyspnea scale (2.54 ± 0.75 versus 1.18 ± 0.56, p < 0.0001). Conclusions: Our results are consistent with those reported in the literature, demonstrating that COPD patients get beneficial effects with the respiratory rehabilitation program. We also showed that RRP can be implemented in primary health care using simple tools, with reasonable costs.


La rehabilitación respiratoria ha demostrado beneficios en mejorar la capacidad física y calidad de vida en los pacientes con EPOC. Sin embargo, en Chile no existe información de programas de rehabilitación respiratoria (PRR) en la atención primaria de salud. El objetivo de nuestro trabajo fue evaluar los resultados de la implementación de un programa de rehabilitación respiratoria (PRR) en pacientes con EPOC en la atención primaria de salud. Material y Método: Estudio prospectivo descriptivo realizado en un centro de salud familiar de Talagante en pacientes con diagnóstico confirmado de EPOC, durante el período julio de 2012 a mayo de 2014. Fueron ingresados al PRR, de 12 semanas de duración, aquellos pacientes que cumplían los criterios de inclusión. Se realizó entrenamiento aeróbico (caminata), entrenamiento de fuerza de extremidades superiores e inferiores (mancuernas, tobilleras y bandas elásticas) y entrenamiento de musculatura respiratoria (válvula umbral), 2 veces por semana y de 90 min de duración cada sesión. Al iniciar y al finalizar el PRR se evaluó: calidad de vida, fuerza muscular, test de marcha de 6 min (TM6); índice BODE y disnea. Resultados: De un total de 79 pacientes con EPOC evaluados, 54 ingresaron al PRR y 39 finalizaron el programa. La edad promedio fue 67,3 ± 8,5 años, 64% de género femenino, índice de masa corporal: 26,97 ± 4,3 kg/m² y VEF1 1,17 ± 0,57 L. Al comparar los valores iniciales y finales del PRR se encontraron diferencias estadísticamente significativas en: TM6 (445,9 ± 77,9 vs 498,2 ± 82,8 m, p < 0,001); Puntaje del cuestionario de St. George (45,1 ± 16,1 vs 18,5 ± 11,5, p < 0,0001), PIMáx 48,95 ± 18,8 vs 57,2 ± 19,4 cm H2O, p < 0,0001), índice BODE (2,76 ± 1,37 vs 1,53 ± 1,0, p < 0,0001), y escala de disnea mMRC (2,54 ± 0,75 vs 1,18 ± 0,56, p < 0,0001). Conclusiones: Los resultados de nuestro estudio son concordantes con lo descrito en la literatura y demuestran los beneficios significativos obtenidos con la rehabilitación respiratoria en pacientes con EPOC. También, se demuestra que en Chile se puede implementar un PRR en la atención primaria utilizando implementos simples y con un bajo costo.

ABSTRACT

Background: The Diabetes Mellitus 2 treatment adherence scale version III (EATDM-III) was devised in Costa Rica. Its seven factors are family support, community organization and support, physical exercise, medical control, hygiene and self-care and assessment of physical condition. Aim: To assess the psychometric properties of the scale in Chilean patients. Material and Methods: The results of the EATDM-III scale, applied to 274 patients with Diabetes Mellitus 2 aged 59 ± 11 years (59% women), were analyzed. Reliability, item, exploratory and confirmatory factorial analyses were carried out both in the initial and the proposed model. Results: We propose a version of 30 items grouped in six dimensions, improving the fit indices obtained with the original scale. The review of item factor loadings shows that all are appropriate both in magnitude and statistical significance, with values between 0.46 and 0.93. Internal consistency measured by Cronbach s alpha, was 0.85 for the total scale. Conclusions: The adapted EATDM-III scale is reliable and can be used to assess treatment adherence in Chilean patients.

ABSTRACT

El embarazo ectópico es la gestación que se anida fuera del endometrio que recubre la cavidad uterina. Se estima una incidencia de 0,94 a 2,6% de todas las gestaciones. Su localización en cicatriz uterina de cesárea previa (0,15%) -una rara presentación de esta patología- representa 6,15% de los casos de embarazo ectópico que ocurren en mujeres con antecedente de cesárea. En el presente artículo se analiza el caso de una paciente de 28 años, gesta 5, para 0412, con antecedente de 3 cesáreas, que acudió al Hospital Nacional Docente Materno Infantil (HONADOMANI) San Bartolomé en febrero 2013 con diagnóstico de embarazo ectópico localizado en cicatriz uterina por cesárea previa, por ecografía transvaginal, y que fue resuelto exitosamente mediante manejo laparoscópico. El embarazo ectópico localizado en la zona de cicatriz uterina por cesárea previa, aunque raro, va en aumento debido al incremento de la tasa de cesáreas. La ultrasonografía transvaginal es crucial para su diagnóstico, y actualmente no existe un consenso o guía clínica que nos oriente en su manejo.


Ectopic pregnancy is a gestation that nests outside of the uterus endometrial lining. Incidence is estimated at 0.94-2.6% of all pregnancies. Its location in a previous cesarean section uterine scar is a rare (0.15%) presentation of this disease, accounting for 6.15% of ectopic pregnancy cases occurring in women with previous cesarean section. A case of a 28 year-old woman G: 5 P: 0412, with history of 3 cesarean sections was hospitalized in Hospital Nacional Docente Materno Infantil (HONADOMANI) San Bartolomé in February 2013 because of transvaginal ultrasound diagnosis of ectopic pregnancy located in previous uterine cesarean scar; it was successfully resolved by laparoscopic management. Cases of ectopic pregnancy located in the uterine scar from previous cesarean are increasing due to the rising cesarean section rate. Transvaginal ultrasonography is crucial for diagnosis. There is no current consensus or guidelines for its management.

ABSTRACT

Colorectal cancer (CRC) is a genetic and epigenetic disease. Approximately one third of the CRC has an hereditary component. Familial adenomatous polyposis (FAP) is an autosomal dominant inherited condition that has its origins in the line of APC gene mutation, which occurs with a frequency of approximately 1:10,000 live births. We report a case of a patient of 25 years with FAP. This review provides current knowledge on the broad clinical spectrum of this disease, also referring to the optimal method of diagnosis, differential diagnosis and management.


El cáncer colorrectal (CCR) es una enfermedad genética y epigenética. Aproximadamente un tercio del CCR tiene un componente hereditario. La poliposis adenomatosa familiar (PAF) es una condición hereditaria autosómica dominante que tiene su origen en la línea de mutación del gen APC, el cual ocurre con una frecuencia aproximada de 1:10.000 nacidos vivos. Se reporta el caso de una paciente de 25 años con PAF. La presente revisión proporciona los conocimientos actuales sobre el amplio espectro clínico de esta enfermedad, refiriéndose también al método óptimo de diagnóstico, diagnóstico diferencial y su manejo.

ABSTRACT

Por iniciativa de tres instituciones: Liga Chilena contra la Epilepsia (LICHE), Sociedad de Epileptología de Chile (SOCEPCHI) y Sociedad de Psiquiatría y Neurología de la Infancia y Adolescencia (SOPNIA) de Chile, se constituye un comité de trabajo que convoca a un consenso de uso de fármacos antiepilépticos (FAEs) en un grupo de 16 Síndromes electro-clínicos y otras Epilepsias en niños y adolescentes. Cuarenta y dos médicos neuropediatras especialistas en Epilepsias de todas las regiones de Chile, participaron en la discusión y realizaron una propuesta de tratamiento farmacológico para cada cuadro. El comité de trabajo realizó un análisis exhaustivo y discusión de los documentos, para finalmente concluir en una recomendación de tratamiento para cada cuadro. Este consenso es una guía práctica de orientación para ayudar a las decisiones de tratamiento en situaciones clínicas concretas. Su objetivo final es ofrecer una mejor calidad de atención a los niños y adolescentes con epilepsias, a través de decisiones fundadas que contribuyan a disminuir la variabilidad de las decisiones terapéuticas.


Committed by three institutions: Liga Chilena contra la Epilepsia (LICHE), Sociedad de Epileptología de Chile (SOCEPCHI) y Sociedad de Psiquiatría y Neurología de la Infancia y Adolescencia (SOPNIA) de Chile, a 6-member working committee called for a meeting of 42 Chilean pediatric epileptologists from all over the country, with the aim of reaching a consensus on the use of antiepileptic drugs in 16 selected children and adolescents electro-clinical syndromes and epilepsies. These treatment proposals were analyzed and fully discussed by the working committee, ending in an antiepileptic drug treatment recommendation guideline for each condition. This consensus is a practical guideline to be used in specific clinical situations, which aims to support treatment decision making. Its main purpose is to offer the best evidence based treatments to our children and adolescents patients with epilepsy, thus contributing to diminish variability in therapeutic decisions.

ABSTRACT

Several studies have shown that poor exercise tolerance in Chronic Obstructive Pulmonary Disease (COPD) patients is multifactorial in origin. However, a major exercise-limiting factor in COPD is peripheral muscle dysfunction, particularly the muscles of the lower extremities, characterized by atrophic muscles and reduced fatigue resistance due to morphological and metabolic alterations of peripheral muscles. This chapter therefore evaluated the scientific evidence regarding the beneficial effect of lower extremities exercise in the pulmonary rehabilitation in COPD patients. The technical characteristics of this exercise training were also reviewed. Exercise training of lower limbs was recommended in respiratory rehabilitation of COPD patients. The lower extremities muscle exercise training provides significant benefits to patients with COPD in terms of reduction of dyspnea and improvemet in exercise capacity and in quality of life (quality level of evidence = A, strong recommendation). Higher-intensity exercise training and with interval exercise of the lower extrmities produces greater physiological benefits.


Diversos estudios han demostrado que la pobre tolerancia al ejercicio de los pacientes con Enfermedad Pulmonar Obstructiva Crónica (EPOC) es de origen multifactorial. Sin embargo, un importante factor limitante del ejercicio en los pacientes con EPOC es la disfunción muscular periférica, sobre todo de los músculos de las extremidades inferiores, que se caracteriza por atrofia muscular y reducida resistencia a la fatiga dado por alteraciones morfológicas y metabólicas de los músculos periféricos. En este capitulo se evaluó la evidencia científica que existe en cuanto a los beneficios del entrenamiento muscular de extremidades inferiores (EEII) en la rehabilitación respiratoria en pacientes con EPOC. También se revisan las características técnicas de dicho entrenamiento. Se recomienda la realización de entrenamiento muscular de EEII en rehabilitación respiratoria de pacientes con EPOC. El entrenamiento muscular de extremidades inferiores otorga significativos beneficios a los pacientes con EPOC en cuanto a disminuir la disnea, mejorar la capacidad de ejercicio y la calidad de vida (calidad de la evidencia A, recomendación fuerte). El entrenamiento de EEII de alta intensidad y con intervalos produce significativos beneficios fisiológicos.

ABSTRACT

We have observed that intracerebroventricular (icv) injection of selective N-methyl-D-aspartic acid (NMDA)-type glutamatergic receptor antagonists inhibits lordosis in ovariectomized (OVX), estrogen-primed rats receiving progesterone or luteinizing hormone-releasing hormone (LHRH). When NMDA was injected into OVX estrogen-primed rats, it induced a significant increase in lordosis. The interaction between LHRH and glutamate was previously explored by us and another groups. The noradrenergic systems have a functional role in the regulation of LHRH release. The purpose of the present study was to explore the interaction between glutamatergic and noradrenergic transmission. The action of prazosin, an alpha1- and alpha2b-noradrenergic antagonist, was studied here by injecting it icv (1.75 and 3.5 µg/6 µL) prior to NMDA administration (1 µg/2 µL) in OVX estrogen-primed Sprague-Dawley rats (240-270 g). Rats manually restrained were injected over a period of 2 min, and tested 1.5 h later. The enhancing effect induced by NMDA on the lordosis/mount ratio at high doses (67.06 ± 3.28, N = 28) when compared to saline controls (6 and 2 µL, 16.59 ± 3.20, N = 27) was abolished by prazosin administration (17.04 ± 5.52, N = 17, and 9.33 ± 3.21, N = 20, P < 0.001 for both doses). Plasma LH levels decreased significantly only with the higher dose of prazosin (1.99 ± 0.24 ng/mL, N = 18, compared to saline-NMDA effect, 5.96 ± 2.01 ng/mL, N = 13, P < 0.05). Behavioral effects seem to be more sensitive to the alpha-blockade than hormonal effects. These findings strongly suggest that the facilitatory effects of NMDA on both lordosis and LH secretion in this model are mediated by alpha-noradrenergic transmission.

ABSTRACT

This is a review of the basic concepts of evidence, medicine, evidence-based medicine and its effects. Evidence-based medicine is a contribution for statistical design and management, that allows the gathering of scientific information, but does not completely exclude bias. Its methodology proceeds with order and caution, generating a highly probable mass of knowledge. The quality of the information obtained from diverse sources such as meta-analysis to expert opinions is classified in different levels according to the «strength¼ of the evidence in which it is based. The best contribution of evidence-based medicine is probably for diseases of incidence and does not replace clinical experience and patients-physician relationship. Basically we treat ill people and not illnesses. Without clinical experience, medical practice can be tyrannized by evidence-based medicine that can become inapplicable or inappropriate. Without evidence-based medicine, medical practice will not be updated, limiting our professional skills.

ABSTRACT

Introducción: La sociedad Internacional de Continencia ha definido: 1. El Síndrome de vejiga hiperactiva (VHA) como un "diagnóstico sintomático" basado en la presencia de urgencia miccional, con o sin incontinencia , usualmente acompañadas de polaquiuria diurna y nocturna, en ausencia obvia de enfermedad metabólica o neurológica. 2. Vejiga Hiperactiva ("detrusor hiperactivo") como una "observación urodinámica" que se caracteriza por contracciones involuntarias del detrusor, durante la fase del llenado que pueden ser espontáneas o provocadas. Sobre la base de estudios poblacionales realizados en Europa y EE. UU. la prevalencia de vejiga hiperactiva (VHA) ha sido reportada en alrededor de 16 por ciento. En la Argentina no se conoce la epidemiología de la VHA y no hemos encontrado publicaciones nacionales en nuestra revisión bibliográfica. Objetivos: Establecer la tasa de prevalencia de VHA por sexo y edad en una población de 3.692 consultas urológicas y 2.030 estudios urodinámicos a fin de conocer la frecuencia e importancia de esta patología en los pacientes que consultaron en nuestro Servicio. Material y Métodos: Estudio de carácter epidemiológico, retrospectivo, sobre una población de 3.692 pacientes que consultaron consecutivamente, de los cuales 2.030 fueron estudiados mediante urodinamia de presión/flujo, estimandose la tasa de prevalencia de VHA. Se recolectó información adicional sobre edad y sexo de los pacientes con el objeto de ajustar la prevalencia de VHA a los diferentes estratos etarios y de género. Conclusiones: La prevalencia de VHA en nuestra población fue del 23,4 por ciento: dos o tres de cada 10 consultas. El 56,5 por ciento de los pacientes con VHA fueron de sexo masculino y el 43,5 por ciento del femenino. El 54 por ciento de todas las VHA ocurrieron en mayores de 60 años, 65 por ciento de las masculinas y 40 por ciento de las femeninas, siendo el riesgo de VHA en nuestra comunidad en ese grupo etario hasta 7 veces superior respecto de la gente más joven. La manifestación clínica prevalente de VHA fue la incontinencia de orina, seguida por la urgencia y la polaquiuria. La incontinencia fue 5 veces más frecuente en mujeres que en hombres y la polaquiuria fue 13 veces más frecuente en hombres que en mujeres

ABSTRACT

Data on the infant and perinatal mortality in the University of the Philippines-Philippine General Hospital Medical Center is presented. Although progress has been made in the reduction of infant and perinatal mortality, figures show that there is much more to be done, especially among the stillbirths and neonatal causes of deaths.

ABSTRACT

Early stimulation has been shown to produce long-lasting effects in many species. Prenatal exposure to some strong stressors may affect development of the nervous system leading to behavioral impairment in adult life. The purpose of the present work was to study the postnatal harmful effects of exposure to variable mild stresses in rats during pregnancy. Female Holtzman rats were submitted daily to one session of a chronic variable stress (CVS) during pregnancy (prenatal stress; PS group). Control pregnant rats (C group) were undisturbed. The pups of PS and C dams were weighed and separated into two groups 48 h after delivery. One group was maintained with their own dams (PS group, N = 70; C group, N = 36) while the other PS pups were cross-fostered with C dams (PSF group, N = 47) and the other C pups were cross-fostered with PS dams (CF group, N = 58). Pups were undisturbed until weaning (postnatal day 28). The male offspring underwent motor activity tests (day 28), enriched environment tests (day 37) and social interaction tests (day 42) in an animal activity monitor. Body weight was recorded on days 2, 28 and 60. The PS pups showed lower birth weight than C pups (Duncan's test, 0.05). The PS pups suckling with their stressed mothers displayed greater preweaning mortality (C: 23 percent, PS: 60 percent; 2 test, 0.05) and lower body weight than controls at days 28 and 60 (Duncan's test, 0.05 and 0.01, respectively). The PS, PSF and CF groups showed lower motor activity scores than controls when tested at day 28 (Duncan's test, 0.01 for PS group and ;0.05 for CF and PSF groups). In the enriched environment test performed on day 37, between-group differences in total motor activity were not detected; however, the PS, CF and PSF groups displayed less exploration time than controls (Duncan's test, 0.05). Only the PS group showed impaired motor activity and impaired social behavior at day 42 (Duncan's test, 0.05). In fact, CVS treatment during gestation plus suckling with a previously stressed mother caused long-lasting physical and behavioral changes in rats. Cross-fostering PS-exposed pups to a dam which was not submitted to stress counteracted most of the harmful effects of the treatment. It is probable that prenatal stress plus suckling from a previously stressed mother can

ABSTRACT

1. The present review discusses the proposed roles of the amino acids glutamate and GABA in the central regulation of luteinizing hormone-releasing hormone (LHRH) and in luteinizing hormone (LH) secretion. 2. Descriptions of the mechanisms of action of these neurotransmitters have focused on two diencephalic areas, namely, the preoptic-anterior hypothalamic area where the cell bodies of LHRH neurons are located, and the medial basal hypothalamus which contains the nerve endings of the LHRH system. Increasing endogenous GABA concentration by drugs, GABA agonists, or blockade of glutamatergic neurotransmission by selective antagonists in rats and non-human primates prevents ovulation and pulsatile LH release, and blunts the LH surges induced by estrogen or an estrogen-progesterone combination. In contrast, glutamate and different glutamate agonists such as NMDA, AMPA and kainate, can increase LHRH/LH secretion. 3. The simultaneous enhancement of glutamatergic activity and a decrease of GABAergic tone may positively influence the maturation of the pituitary-gonadal system in rats and non-human primates. Administration of glutamate receptor agonists has been shown to significantly advance the onset of puberty. Conversely, glutamate antagonists or increased endogenous GABA levels may delay the onset of puberty. The physiological regulation of LHRH/LH secretion may thus involve a GABA-glutamate interaction and a cooperative action of the various types of ionotropic glutamate receptors. 4. The inhibitory actions of GABA on LH release and ovulation may be exerted at the level of afferent nerve terminals that regulate LHRH secretion. A likely candidate is noradrenaline, as suggested by the synaptic connections between noradrenergic nerve terminals and GABAergic interneurons in the preoptic area. Recent experiments have provided complementary evidence for the physiological balance between inhibitory and excitatory transmission resulting in modulation of the action of noradrenaline to evoke LHRH release.

ABSTRACT

Se estudiaron las concentraciones (pg/mg de tejido de los neurotransmisores (NT) 5-Hidroxitriptamina (5HT), Noradrenalina (NA) y Dopamina (DA) en mucosa del fundus gástrico (F), antro (A) y bulbo duodenal (D) de 21 paciente con mucosa normal y con diversos grados de inflamación crónica. Se correlacionaron las concentraciones de los NT entre sí, en conjuntos en cada región y con parámetros clínicos, de motilidad indirectos e histológicos. Los valores promedios hallados en cada región fueron para 5HT: F=940+/-457, en A=787+/-407 y en D=601+/-272; para NA en F=217+/-138, en A=228+/-126 y en D=245+/-118; y para DA en F=50+/-32, en A=46+/-31 y en D=53+/-45. Se observó que a mayores infiltrados inflamatorios en bulbo duodenal se encontraron mayores concentraciones de DA (r=0,94). Ningún otro parámetro tuvo relación significativa con las variaciones de los NT. Se pudo establecer que las variaciones de las concentraciones de los NT de la mucosa del antro gástrico están más asociadas a las del bulbo duodenal que a las del fundus gástrico

ABSTRACT

La encefalitis herpética es la causa más frecuente de encefalitis esporádica de curso grave. Su sospecha y diagnóstico de certeza son difíciles. Por esta razón se analizaron 5 fichas clínicas con diagnóstico de encefalitis herpética, demostrado por aislamiento (+) del virus en cultivo de LCR. Se revisó la clínica y exámenes y se correlacionó con lo descrito en la literatura. Se hizo especial mención al cultivo de LCR, como alternativa en el diagnóstico definitivo
