RESUMO

INTRODUCCIÓN: El síndrome de hiperestimulación ovárica es una respuesta exagerada del ovario a los tratamientos hormonales para estimular la formación de óvulos. OBJETIVO: Describir el caso clínico de una mujer con síndrome de hiperestimulación ovárica; revisar el abordaje, manejo, tratamiento y cómo prevenirlo. CASO CLÍNICO: Paciente femenina de 37 años, multigesta, en tratamiento con metformina por Síndrome de ovario poliquístico , que presenta infertilidad secundaria a factor tubárico, que desarrolló un cuadro moderado de síndrome de hiperestimulación ovárica como consecuencia de la aplicación de las técnicas de fertilización in vitro (Folitropina alfa humana recombinante (GONAL-F®) y Cetrolerelix (CETROTIDE®); al cuarto día del procedimiento de aspiración folicular presenta dolor pélvico intenso, disuria, deposiciones diarreicas, ecografía abdominal y vaginal evidencia líquido libre en cavidad alrededor de 1000cc, además de ovarios tanto derecho e izquierdo con volumen de 102 mL y 189 mL respectivamente. Paciente es ingresada para realizar tratamiento hidratación parenteral, Enoxaparina 40mg subcutánea, Cabergolina 0.5mg vía oral, alta a las 72 horas. DISCUSIÓN: Las claves para la prevención del síndrome de hiperestimulación ovárica son la experiencia con la terapia de inducción de la ovulación y el reconocimiento de los factores de riesgo para el síndrome de hiperestimulación ovárica. Los regímenes de inducción de la ovulación deberían ser altamente individualizados, monitorizados cuidadosamente y usando dosis y duración mínimas del tratamiento con gonadotropinas para conseguir la meta terapéutica. CONCLUSIONES: El síndrome de hiperestimulación ovárica constituye la complicación más temida durante el uso de inductores de la ovulación; el conocimiento de factores de riesgo, puede prevenir o evitar que llegue a ser de un caso severo, lo cual puede causar mayor morbilidad o hasta mortalidad. La vitrificación se convierte en la técnica que permite prevenir el síndrome de hiperestimulación ovárica, junto con esta técnica hay 2 alternativas: la inducción con análogo de la hormona liberadora de gonadotropina o el uso de agonistas dopaminérgicos.


INTRODUCTION: Ovarian hyperstimulation syndrome is an exaggerated response of the ovary to hormonal treatments to stimulate egg formation. OBJECTIVE: To describe the clinical case of a woman with ovarian hyperstimulation syndrome; to review the approach, management, treatment and how to prevent it. CLINICAL CASE: 37-year-old female patient, multigestation, under treatment with metformin for polycystic ovary syndrome, presenting infertility secondary to tubal factor, who developed a moderate picture of ovarian hyperstimulation syndrome as a consequence of the application of in vitro fertilization techniques (recombinant human follitropin alfa (GONAL-F®) and Cetrolerelix (CETROTIDE®); On the fourth day of the follicular aspiration procedure she presents intense pelvic pain, dysuria, diarrheic stools, abdominal and vaginal ultrasound shows free fluid in the cavity of about 1000cc, in addition to right and left ovaries with a volume of 102 mL and 189 mL respectively. Patient was admitted for parenteral hydration treatment, Enoxaparin 40mg subcutaneous, Cabergoline 0.5mg orally, discharged after 72 hours. DISCUSSION: The keys to prevention of ovarian hyperstimulation syndrome are experience with ovulation induction therapy and recognition of risk factors for ovarian hyperstimulation syndrome. Ovulation induction regimens should be highly individualized, carefully monitored, and using minimal doses and duration of gonadotropin therapy to achieve the therapeutic goal. CONCLUSIONS: Ovarian hyperstimulation syndrome constitutes the most feared complication during the use of ovulation inducers; knowledge of risk factors, may prevent or avoid it from becoming a severe case, which may cause increased morbidity or even mortality. Vitrification becomes the technique that allows preventing ovarian hyperstimulation syndrome, along with this technique there are 2 alternatives: induction with gonadotropin-releasing hormone analog or the use of dopaminergic agonists.

RESUMO

Background: Hypovitaminosis D has a high prevalence among patients with chronic kidney disease (CKD). Aim: To determine the prevalence of 25 hydroxy vitamin D (25(OH) D) insufficiency and deficiency in pediatric patients on dialysis and kidney transplantation. Material and Methods: Serum calcium and phosphorus, parathormone (PTH), alkaline phosphatases and 25 (OH)D were measured in 13 children on hemodialysis (HD), 18 on peritoneal dialysis (PD) and 53 that received an allograft (Tx), aged 9.8 ± 4.6 years (51 percent females). Results: Fifty four percent of patients had height Z score less than -1.88. Patients on HD had the lowest values. The average time of replacement therapy was 2.9 ± 2.8 years. Mean 25(OH)D levels in all was 18.7 ± 10.7ng/ml (HD: 21 ± 16.8, PD: 18.9 ± 8.5, Tx: 18.1 ± 9.72 ng/ml). Eighty eight percent of patients had levels below 30 ng/ml. Mean of serum calcium was 9.5 ± 0.64 mg/dl, serum phosphorus 5.03 ± 1.02 mg/dl, calcium-phosphorus product 48 ± 11.8 mg/dl and alkaline phosphatases 300.5 ± 171.3 IU/L. Average PTH values in dialyzed and Tx patients were 724.6 ± 640.5 and 107.7 ± 56.2 pg/ml, respectively (p < 0.001). A positive correlation between 25 (OH) D and calcium levels among PD patients was observed (r = 0.490, p = 0.04). Conclusions: Hypovitaminosis D is highly prevalent among children on renal substitution therapy, regardless of the type of therapy used and the stage of renal failure.

RESUMO

The hRAD54 gene is a key member of the RAD52 epistasis group involved in repair of double-strand breaks (DSB) by homologous recombination (HR). Thus, alterations of the normal function of these genes could generate genetic instability, shifting the normal process of the cell cycle, leading the cells to develop into cancer. In this work we analyzed exon 18 of the hRAD54 gene, which has been previously reported by our group to carry a silent polymorphism, 2290 C/T (Ala730Ala), associated to meningiomas. We performed a PCR-SSCP method to detect the polymorphism in 239 samples including leukemia and normal control population. The results revealed that the 2290 C/T polymorphism has frequencies of 0.1 for the leukemia and 0.1 for the control group. These frequencies show no statistical differences. Additionally, we dissected the leukemia group in chronic myelogenous leukemia (CML) and acute lymphoblastic leukemia (ALL) to evaluate the polymorphism. The frequencies found in these subgroups were 0.14 for CML and 0.05 for ALL. We found statistically significant differences between CML patients and the control group (p < 0.05) but we did not find significant differences between ALL and the control group (p > 0.05). These results suggest a possible link between the 2290 C/T polymorphism of the hRAD54 gene and CML.

RESUMO

El maltrato infantil es una realidad de gran relevancia en todos los países del mundo. En Chile, el Tercer Estudio de Maltrato Infantil realizado por el Fondo de Naciones Unidad para la infancia [UNICEF] en el año 2006, muestra que el 75.3% de los niños recibe algún tipo de violencia ya sea física o psicológica que pueden derivar en graves consecuencias en la salud. Se presenta el estudio de caso desarrollado durante la experiencia clínica en un hospital pediátrico de la Región Metropolitana y plantea las intervenciones de enfermería en niños/as hospitalizados por observación de maltrato infantil. El personal de enfermería cumple un rol esencial en el proceso de recuperación de la salud en situaciones de maltrato infantil. Es importante considerar el contexto y etapa del ciclo vital en la que se encuentra el niño, así como identificar y potenciar sus capacida­ des y las de su cuidador, fomentando la resiliencia, potenciando el apego y el autocuidado, con el fin de promover ambientes seguros que permitan el óptimo desarrollo biosicosocial del niño.


Child abuse is an issue of great relevance in Chile. The Third Study of Child Abuse created by the United Nations International Children's Emergency Fund [UNICEF] in 2006, showed a 75.3% of children are victims of any kind of violence, which can be physical or psychological, and may result in serious complications in their health. This study was done during a clinical experience in a children's hospital of Metropolitan Region and pretends to pose nursing interventions to hospitalized children for child abuse. The nursing staff fulfills a vital role in the process of health recovery in child abuse cases. It is important to consider both the child's context and vital cicle stage, as well as identifying and enhancing the abilities of both the child in question and the person taking care of him, promoting resilience, increasing attachment to others and self-caring with the aim of contributing safe environments that allow the child's effective biological, psychological and social development.

RESUMO

Resumen: El principal objetivo de este estudio consistió en determinar la prevalencia de polimorfismos de los genes Apolipoproteina E (Apo E) y Glutatión Peroxidasa 1 (GPX-l), y su influencia en el desarrollo de la enfermedad de Alzheimer en población ecuatoriana. Se realizó un estudio transversal caso-control. El grupo de estudio (n=39) estuvo conformado por pacientes con enfermedad de Alzheimer. El grupo de control (n=39) estuvo conformado por adultos mayores no diagnosticados con demencia y presentaron la misma edad y nivel de educación. El período de inclusión fue del 2007 al 2008. Para el análisis gen ético se extrajo ADN de sangre periférica en el cual se determinó el genotipo de cada individuo mediante la técnica PCR-RFLP. Se encontró asociación positiva de los alelos E4 y E2 del gen Apo E en individuos con enfermedad de Alzheimer (EA) con odds ratio (OR) de 2.40 y 2.58, respectivamente. El gen GPX-I demostró una fuerte asociación del alelo Leu con OR 5.05; mientras que el alelo Pro demostró asociación negativa con OR 0.27. Para concluir, el alelo Leu del gen GPX-I es un factor de riesgo para este trastorno neurodegenerativo.

RESUMO

We analyzed the consequences of aerial spraying with glyphosate added to a surfactant solution in the northern part of Ecuador. A total of 24 exposed and 21 unexposed control individuals were investigated using the comet assay. The results showed a higher degree of DNA damage in the exposed group (comet length = 35.5 µm) compared to the control group (comet length = 25.94 µm). These results suggest that in the formulation used during aerial spraying glyphosate had a genotoxic effect on the exposed individuals.
