Tratamiento del embarazo ectópico en cicatriz de cesárea: revisión de la literatura a propósito de 3 casos / Treatment of ectopic pregnancy in a cesarean scar: review of the literature regarding 3 cases

INTRODUCCIÓN Y OBJETIVOS: El embarazo en cicatriz de cesárea previa (ECC) es una entidad poco frecuente que puede tener graves consecuencias. Hasta la fecha no existen esquemas estandarizados de tratamiento y su manejo óptimo sigue siendo controvertido. Nuestro objetivo es realizar una revisión de la literatura publicada sobre el manejo del ECC y proponer un algoritmo. También exponemos tres casos de ECC resueltos con diferentes tratamientos en el Hospital Universitario Infanta Elena MÉTODOS: Búsqueda de la literatura en bases de datos utilizando las palabras clave: "embarazo en cicatriz cesárea"," gestación ectópica en cicatriz cesárea", "tratamiento", "manejo". RESULTADOS: Las opciones terapéuticas pueden ser médicas, quirúrgicas o una combinación de ambas. Los tratamientos quirúrgicos tienen altas tasas de éxito, sin embargo, son más invasivos y no están exentos de riesgo. La combinación de tratamientos parece aumentar la tasa de éxito, no obstante, podría implicar un mayor riesgo de efectos secundarios y costes. CONCLUSIONES: El manejo de los ECC debe de ser individualizado, basado en la evidencia científica, en los medios disponibles y la experiencia de los profesionales en los distintos procedimientos, guiándonos por el tipo de ECC y su grado de vascularización e invasión, grosor del miometrio, niveles de beta-hCG, presencia de actividad cardiaca, clínica y estabilidad hemodinámica de la paciente. Deben tenerse en cuenta las circunstancias y patología intercurrente de la mujer, así como su deseo genésico o de preservación del útero.

INTRODUCTION AND OBJECTIVES: Cesarean scar pregnancy (CSP) is a rare entity that can cause serious consequences. Up to now, there are no standardized treatment schemes, and its optimal management remains controversial. Our objetive is to review the literature regarding CSP management and propose an algorithm. We also present three cases of CSP resolved with different treatments at Hospital Universitario Infanta Elena. METHODS: Literature search in databases using the following keywords: pregnancy with cesarean section, ectopic pregnancy with cesarean section, treatment, management. RESULTS: The therapeutic options can be medical, surgical or a combination of both. Surgical treatments have high success rates; however, they are more invasive and are not without risk. The combination of treatments seems to increase the success rate; however, it could imply a higher risk of side effects and costs. CONCLUSIONS: The management of CSP must be individualized; based on scientific evidence, on the means available, and on the experience of the professionals in the different procedures; guided by the type of CSP and its degree of vascularization and invasion, by the thickness of the myometrium, beta-hCG levels, presence of cardiac activity, and by clinical and hemodynamic stability of the patient. The circumstances and intercurrent pathology of the patient must be considered, as well as her desire for future pregnancy or preservation of the uterus.

A propósito de un caso: útero miomatoso gigante torsionado / Torsion of a giant miomatous uterus: report of a clinical case autores

OBJETIVO: Reportar el caso de una torsión de útero, trompas y ambos ovarios a nivel de cuello uterino. Describir la patogenia, sintomatología y tratamiento, como un caso infrecuente y potencialmente grave, en la práctica clínica diaria. MATERIAL Y MÉTODOS: Analizar el curso de esta extremadamente rara patología, en una mujer postmenopáusica de 59 años. Se trata de un caso raro de torsión uterina en un útero no gestante, reportando los hallazgos en los exámenes previos a la cirugía y los hallazgos intraoperatorios e histopatológicos postcirugía. La resonancia magnética fue fundamental en el diagnóstico de la paciente y la laparotomía realizada demostró una torsión de cuerpo uterino de 360 ° a nivel de cérvix, y un gran mioma pediculado con signos de necrosis. Hemos revisado los últimos artículos de esta rara patología RESULTADOS Y DISCUSIÓN: La paciente fue operada. Se realizó una histerectomía total mediante una laparotomía media supra e infraumbilical. Los ovarios no tenían signos de necrosis. CONCLUSIONES: Debemos tener en cuenta esta posibilidad diagnóstica, en pacientes con aumento de tamaño uterino y clínica de dolor abdominal, ya que aunque es muy infrecuente, su diagnóstico es importante, ya que puede ser peligroso para la vida de la paciente.

OBJECTIVE: To report a case of torsion of the uterus, fallopian tubes and both ovaries around the uterine collum and the symptomatology, pathogenesis and treatment of this uncommon pathology. MATERIAL AND METHODS: The article analyses the course of this extremely rare pathology in a postmenopausical woman of 59 years. It is a rare case like a non gravid uterine torsion in a postmenopausical woman. We have the exams previous to the surgery, the finds intraoperative and the histolopathological reports postsurgery. RMN was the most important in diagnosis and the laparotomy showed a 360° an uterus increased on size and a big pedunculated myoma with signs of necrosis We have reviewed the latest articles on this strange pathology RESULTS AND DISCUSSION: The patient was operated. A infra-supra medium laparotomy was practiced and a total hysterectomy was made. Ovarians had not signs of necrosis. CONCLUSIONS: We must take into account, in patients with pathologies that increase uterine size and abdominal pain, the possibility of uterine torsion. Although it is a very infrequent pathology, its diagnosis is important, since it can be dangerous for the life of the patient

["CLAPSEN", a global approach to the rehabilitation of severe childhood malnutrition in Bolivia]. / Le <>, une démarche globale pour la réhabilitation nutritionnelle de l'enfant gravement mal nourri en Bolivie.

The "CLAPSEN" approach was developed at the Hospital Materno Infantil German Urquidi in Cochabamba, to provide a global response for the study and treatment of childhood malnutrition. "CLAPSEN" is short for Clinical, Laboratory, Anthropometry, Psychology, Sociology, Nursing (Enfermera in Spanish) and Nutritional care. Most of the malnourished children admitted to Cochabamba Hospital are from poor families, more than three quarters of whom have only recently arrived in the city. Acute malnutrition is just one of the manifestations of a generally unfavorable environment. Malnutrition should not be considered as a simple deficiency in energy, protein or micronutrients, but rather as a multi-deficiency syndrome, also involving a lack of basic health and social care. This study demonstrates that malnourished children display a considerable degree of psychological retardation and of immune system depression. After five weeks of rehabilitation, the children were considered to have recuperated physically, as assessed by anthropometry, but not psychologically, as assessed by the adapted Dewer Score, or immunologically, as shown by the size of the thymus or the extent of maturation of lymphocytes. This strategy was not designed as a long-term approach for treating malnutrition, but rather as a research project to characterize the children arriving at the hospital, to determine the reasons for their malnutrition and to identify strategies that could be implemented earlier by health centers of social services, to prevent deterioration in the condition of these children to severe malnutrition requiring hospital admission. We believe that, in this Latin American context, in which the rate of acute malnutrition is low, the hospital should continue to be involved in the treatment of severely malnourished children with associated diseases. The child's stay in hospital should be short and once the child has recovered clinically, he should be sent home. In light of the observed levels of social deprivation, psychosocial and immune deficits, there appears to be a need for continued support for the family, to ensure the full recovery of the child and to prevent relapses.

Immune recovery of malnourished children takes longer than nutritional recovery: implications for treatment and discharge.

Protein-energy malnutrition decreases cellular immunity yet immune recovery has rarely been investigated during nutritional rehabilitation. Malnourished children from low income families of Cochabamba (Bolivia) were hospitalized for 2 months in the Center for Immune and Nutritional Rehabilitation (CRIN), of the German Urquidi Materno-Infantil Hospital. They received a special four-step diet. Nutritional status was determined by a daily clinical examination and weekly anthropometric measurements. Immune status was assessed by weekly ultrasonography of the thymus. The classical criterion for discharge (90 per cent of median reference weight for height) was reached after the first month, whereas a 2-month period was required for complete immunologic recovery. The children belonged to disadvantaged population groups with high exposure to disease. In such an environment, discharge based only on nutritional status after 1 month of treatment could explain frequent relapses because the children were still immunodepressed.

[Immuno-nutritional recovery of children with severe malnutrition]. / Réhabilitation immunonutritionnelle d'enfants atteints de malnutrition sévère.

In developing countries, more than 12 million children die each year from the combined effects of malnutrition and infection. Malnourished children have impaired cellular immunity and are particularly sensitive to opportunistic infections. However, immune recovery has rarely been investigated during nutritional rehabilitation. Indeed, mortality remains high during renutrition, and relapses are frequent. We established a center in Cochabamba, Bolivia, specifically to save these children by treating both clinical and nutritional problems and restoring immune function. The CRIN (center for immuno-nutritional recovery) admits children with severe malnutrition from the Cochabamba suburban area. They are from low income families, in crowded living conditions with poor sanitation and are weaned early. Nutritional diagnosis was based on weight-for-height, arm to head circumference ratio and clinical examination for edema, loss of subcutaneous tissue and diminished muscle mass. The children were examined daily, and first treated for respiratory and intestinal infections. Sociological and psychological aspects were also included in our holistic approach to treating severe malnutrition. Children received a four-stage diet lasting 2 months. During the initial phase (1 week) they were given an oil-sugar-milk based diet, with half lactose concentration, seven times a day. This supplied 1.5 to 2.5 g of protein and 120 to 150 kcal/kg of body weight, according to the PEM pattern. Protein and energy intake was then slowly increased during the transition phase (1 week). During the next, 'calorific-protein bombing' phase (6 weeks) 5 g of protein and 200 kcal/kg of body weight were given daily, such that there was sufficient energy for protein accumulation. During the last, discharge phase (1 week), the protein and energy contents were slowly decreased. Weight, height, arm and head circumferences, and triceps skin-fold thickness were measured weekly by standardized methods. Thymus size was assessed weekly by mediastinal ultrasound scanning with a portable scanner (ALOKA SSD-210 DXII, Tokyo) using a 5 MHz linear pediatric probe. Lymphocyte subpopulations in peripheral blood were investigated monthly using monoclonal antibodies. Compared to controls, the malnourished group had severe involution of the thymus, a significantly higher proportion of circulating immature T lymphocytes and a lower proportion of mature T lymphocytes. The two month longitudinal study showed that normal anthropometric values (90% NCHS weight for height) were recovered after one month of rehabilitation. However, immune recovery (thymic area of 350 nm2) required two months. This may explain the frequent relapses among malnourished children discharged after one month on the basis of 'apparent nutritional health'. Such children may remain immunodepressed, and should therefore be considered as high risk children. To test an immunostimulatory treatment, we designed a historical cohort study of malnourished children who received 2 mg of zinc per day. The children were matched for age, sex, anthropometric criteria and nutritional status with malnourished control children (treated previously with zinc). Anthropometric recovery was obtained in both groups in one month. Children receiving zinc attained immunological recovery within one month, whereas children not receiving zinc took two months. Thus zinc hastened immunological recovery concomitant with nutritional recovery such that the duration of hospitalization could be halved: after one month of this immuno-nutritional treatment, malnourished children appear to be sufficiently healthy to face their pathogenic home environment.

In vitro lymphocyte-differentiating effects of thymulin (Zn-FTS) on lymphocyte subpopulations of severely malnourished children.

This work investigates how thymic dysfunction contributes to the depression of cell-mediated immunity in protein-energy malnutrition (PEM). In Bolivian children hospitalized for severe PEM, the size of the thymus was measured by echography, and the lymphocyte subpopulations were detected by using monoclonal antibodies. These data were compared with those obtained from healthy control subjects. Regardless of the clinical form of PEM, our results show a high degree of T lymphocyte immaturity in severely malnourished children, which correlates with a severe involution of the thymus. Before in vitro incubation with thymulin, this significant increase in the percentage of circulating immature T lymphocytes was concomitant with a decrease in mature T lymphocytes and a slight increase in cytotoxic T subpopulations. After in vitro incubation with thymulin, immature T lymphocytes decreased and mature T lymphocytes increased.

Radioinmunoanalisis de adrenalina y noradrenalina en fetos normales a termino. / Radioimmunoanalysis of adrenaline and noradrenaline in normal term fetus

Para establecer los valores promedio de adrenalina y noradrenalina plasmaticos en fetos normales a termino, fueron seleccionados 27 mujeres que cursaron con embarazo normal, a termino por amenorrea y cuyo parto fue eutocico; la respuesta de los recien nacidos fue totalmente fisiologica.A cada uno de los fetos se le tomaron 10 ml de sangue total del cordon umbilical y se determinaron adrenalina y noradrenalina con la tecnica de Yalow y Berson. Los resultados obtenidos fueron para la adrenalina un promedio de 100.3 ng/ml y para la noradrenalina de 85.7. Estadisticamente, se encontro una correlacion positiva entre ambas. Las cifras de adrenalina fetales no fueron influidas por la edad materna, antecedentes de paridad, edad gestacional, peso de los productos o sexo de los mismos. En relacion con la noradrenalina fetal, tampoco influyeron esas variables, excepto en el peso de los productos, pues se observo una ligera tendencia a elevarse, conforme se incrementa el peso de los productos, sin embargo, se requiere de una muestra mayor, para lograr conclusiones definitivas

[Clinical observation in the premature rupture of membranes. Early detection of maternofetal infections]. / Observación clínica en la ruptura prematura de membranas. Detección precoz de infecciones maternofetales.

One hundred patients with term pregnancy, were studied. There were placed in two groups of 50 each; one was the problem group with antecedents and confirmation of premature rupture of membranes; and the other group with intact amnios at the time of delivery, which served as controls. Clinical history, leukocyte count, temperature determination on admission and during trans-partum, leukocyte count in mixed blood from the umbilical cord and clinical surveillance were carried out, until 96 hours after delivery, of mother and child looking for sepsis signs. In the problem group there were 10 cases of maternal infection and 12 of newborns. There were no infections in the control group. There was no perinatal mortality. The most useful examination as to maternal and neonatal infection, was leukocytic count on admission, followed by trans-partum count and maternal temperature. Fetal leukocytic count above 12,500 per mm3 was useful in 70% of the newborns with complications.
