ABSTRACT

OBJECTIVES: Analyzing associated factors with vasoplegic shock in the postoperative period of Cardiac Surgery. Analyzing the influence of vasopressin as rescue therapy to first-line treatment with norepinephrine. DESIGN: Cohort, prospective and observational study. SETTING: Main hospital Postoperative Cardiac ICU. PATIENTS: Patients undergoing cardiac surgery with subsequent ICU admission from January 2021 to December 2022. INTERVENTIONS: Record of presurgical, perioperative and ICU discharge clinical variables. MAIN VARIABLES OF INTEREST: chronic treatment, presence of vasoplegic shock, need for vasopressin, cardiopulmonary bypass time, mortality. RESULTS: 773 patients met the inclusion criteria. The average age was 67.3, with predominance of males (65.7%). Post-CPB vasoplegia was documented in 94 patients (12.2%). In multivariate analysis, vasoplegia was associated with age, female sex, presurgical creatinine levels, cardiopulmonary bypass time, lactate level upon admission to the ICU, and need for prothrombin complex transfusion. Of the patients who developed vasoplegia, 18 (19%) required rescue vasopressin, associated with pre-surgical intake of ACEIs/ARBs, worse Euroscore score and longer cardiopulmonary bypass time. Refractory vasoplegia with vasopressin requirement was associated with increased morbidity and mortality. CONCLUSIONS: Postcardiopulmonary bypass vasoplegia is associated with increased mortality and morbidity. Shortening cardiopulmonary bypass times and minimizing products blood transfusion could reduce its development. Removing ACEIs and ARBs prior to surgery could reduce the incidence of refractory vasoplegia requiring rescue with vasopressin. The first-line treatment is norepinephrine and rescue treatment with VSP is a good choice in refractory situations. The first-line treatment of this syndrome is norepinephrine, although rescue with vasopressin is a good complement in refractory situations.

ABSTRACT

La preeclampsia representa una complicación específica de hipertensión del embarazo, que aparece de novo después de la 20 semana de gestación, acompañada de proteinuria y/o disfunción orgánica materna o útero-placentaria. A pesar de una etiopatogenia incierta, la alteración en el remodelado vascular de la arteria espiral e isquemia placentaria es la hipótesis más generalizada. El hallazgo de niveles elevados de copeptina, en mujeres con preeclampsia respecto a gestantes normales, ha puesto en valor la implicación de la arginina-vasopresina en la etiopatogenia de esta complicación. En este trabajo se considera su utilidad como marcador de preeclampsia a través de la revisión de los principales estudios efectuados con esta molécula.(AU)


Preeclampsia represents a specific complication of pregnancy hypertension, which appears de novo after the 20th week of gestation, accompanied by proteinuria and/or maternal or utero-placental organ dysfunction. Despite an uncertain etiopathogenesis, impaired vascular remodeling of the spiral artery and placental ischemia is the most widespread hypothesis. The finding of elevated levels of copeptin in women with preeclampsia compared to normal pregnant women has valued the involvement of arginine vasopressin in the etiopathogenesis of this complication. In this paper, its usefulness as a marker of preeclampsia is considered through the review of the main studies carried out with this molecule.(AU)

ABSTRACT

Introducción: Se ha postulado que el uso de vasopresina tendría efectos beneficiosos en el postoperatorio de cirugía cardiovascular. Objetivo: Evaluar la respuesta a la vasopresina en el postoperatorio (POP) de cirugía de Fontan de nuestra población. Métodos: Estudio de casos y controles anidados en una cohorte retrospectiva. Se incluyeron pacientes con cirugía de Fontan entre 2014 y 2019. Se registraron variables demográficas, datos del cateterismo pre-Fontan, días de asistencia respiratoria mecánica (ARM), necesidad de inotrópicos, diuréticos, diálisis, dieta hipograsa, octreotide, sildenafil y nutrición parenteral total (NPT); balance de fluidos al primer y segundo día POP, necesidad de cateterismo en el POP, días de permanencia de tubo pleural, días de internación, necesidad de reinternación y mortalidad. Se compararon los grupos con y sin vasopresina utilizando la prueba de Mann- Whitney-Wilcoxon test. Se consideró significativa una p < 0.05. Resultados: Del total analizado, 35 pacientes recibieron vasopresina. En el grupo control fueron 58 pacientes con características similares de gravedad sin vasopresina. No se encontraron diferencias en la evolución postoperatoria entre ambos grupos. El grupo con vasopresina recibió en mayor proporción dieta hipograsa. Conclusiones: En nuestra serie el uso de vasopresina no marcó diferencias significativas en términos de morbimortalidad con relación al grupo control (AU)


Introduction: The use of vasopressin has been suggested to have beneficial effects in the postoperative period after cardiovascular surgery. Objective: To evaluate the response to vasopressin in the postoperative period (POP) of Fontan surgery in our population. Methods: Nested case-control study in a retrospective cohort. Patients who underwent Fontan surgery between 2014 and 2019 were included. Demographic variables, pre-Fontan catheterization data, days of mechanical ventilation (MRA), need for inotropics, diuretics, dialysis, low-fat diet, octreotide, sildenafil and total parenteral nutrition (TPN); fluid balance at first and second day POP, need for catheterization at POP, duration of chest tube drainage, days of hospitalization, need for readmission, and mortality were recorded. Groups with and without vasopressin were compared using the Mann-Whitney- Wilcoxon test. A p < 0.05 was considered significant. Results: Of all patients analyzed, 35 received vasopressin. The control group consisted of 58 patients with similar severity characteristics who did not receive vasopressin. No differences were found in the postoperative outcome between the two groups. The vasopressin group received a higher proportion of low-fat diet. Conclusions: In our series the use of vasopressin did not show significant differences in terms of morbidity and mortality compared to the control group (AU)

ABSTRACT

Los tumores hipofisarios (TH) suponen el 15% de los tumores intracraneales, y afectan del 10,7 al 14,4% de la población, si bien la incidencia de los TH clínicamente relevantes es de 5,1 casos/100.000 habitantes. El tratamiento quirúrgico está indicado en los TH que cursan con hipersecreción hormonal (a excepción de los TH productores de prolactina), así como en aquellos con clínica compresiva local o neurológica global. Los pacientes con TH requieren una atención multidisciplinar, idealmente en un centro de excelencia y basada en un protocolo asistencial bien definido. Con el objetivo de facilitar y estandarizar la práctica clínica ante este tipo de tumores, el presente documento recoge el posicionamiento del ÿrea de Conocimiento de Neuroendocrinología de la Sociedad Española de Endocrinología y Nutrición (SEEN) y la Sociedad Española de Neurocirugía (SENEC) sobre el manejo y el seguimiento prequirúrgico, quirúrgico y posquirúrgico del paciente con un TH (AU)


Pituitary tumors (PT) account for 15% of intracranial tumors affect 10.7 to 14.4% of the population although the incidence of clinically relevant PT is 5.1 cases/100,000 inhabitants. Surgical treatment is indicated in PTs with hormone hypersecretion (except for prolactin-producing PTs) and those with local compressive or global neurological symptoms. Multidisciplinary care, is essential for patients with PTs, preferably delivered in a center of excellence and based on a well-defined care protocol. In order to facilitate and standardize the clinical procedures for this type of tumor, this document gathers the positioning of the Neuroendocrinology Knowledge Area of the Spanish Society of Endocrinology and Nutrition (SEEN) and the Spanish Society of Neurosurgery (SENEC) on the management of patients with PTs and their preoperative, surgical and postoperative follow-up (AU)

ABSTRACT

Dentro de la patología intracavitaria estructural, los miomas submucosos plantean una mayor dificultad de manejo frente a los pólipos. Dentro de los miomas submucosos los miomas tipo0 y1 son más fáciles de tratar, dado que su separación del miometrio subyacente es técnicamente más fácil. Así, las cirugías histeroscópicas más complicadas son actualmente las miomectomías de miomas submucosos tipo2.Se ha empezado a describir también el manejo histeroscópico de miomas tipo3 por histeroscopia.Con este artículo planteamos hacer una revisión de los puntos más relevantes para llevar a cabo un tratamiento adecuado de este tipo de miomas, revisando su diagnóstico, las técnicas quirúrgicas, la preparación de la paciente y la forma de evitar complicaciones quirúrgicas.(AU)


Within structural intracavitary pathology, submucosal myomas are more difficult to manage than polyps. Of the submucosal myomas, type0 and type1 are easier to treat because their separation from the underlying myometrium is technically easier. Therefore, the most complicated hysteroscopic surgeries are currently type2 submucosal myomectomies.We have also begun to describe the hysteroscopic management of type3 myomas.With this article we propose to make a review of the most relevant points for the correct treatment of this type of myoma, reviewing its diagnosis, surgical techniques, patient preparation, and how to avoid surgical complications.(AU)

ABSTRACT

La hiponatremia es el trastorno electrolítico más frecuente en pacientes hospitalizados y el síndrome de secreción inadecuada de hormona antidiurética (SIADH), la causa más frecuente de hiponatremia con volumen extracelular clínicamente normal. Se trata de un trastorno de la regulación del agua corporal que obedece a diferentes causas, entre las que destacan las neoplasias, las enfermedades pulmonares, los trastornos del sistema nervioso central y diversos fármacos. Como en cualquier hiponatremia, es importante un conocimiento fisiológico de la regulación del agua y del sodio corporal y aplicar unos criterios diagnósticos precisos de cara a un tratamiento eficaz. Los datos disponibles hasta el momento demuestran que el diagnóstico clínico de SIADH realizado por profesionales no se sustenta sobre los criterios establecidos por expertos y esta carencia probablemente impacta en los resultados terapéuticos. La base del tratamiento del SIADH es corregir su causa, la restricción hídrica con el aporte de solutos (cloruro sódico) y el uso de vaptanes en caso de falta de respuesta a las medidas anteriores. (AU)


Hyponatremia is the most frequent electrolytic disorder in hospitalized patients, and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH), the most frequent cause of hiponatremia with clinically normal extracellular volume. It consists of a disorder of the regulation of body water that obeys to different causes, mainly cancer, pulmonary illnesses, disorders of the central nervous system and diverse drugs. As in any hiponatremia it a physiological knowledge of the regulation of body water and sodium is essential as well as the application of precise diagnostic criteria in order to manage the problem with an effective treatment. The available data until the moment show that the clinical diagnosis of SIADH made by professionals is mainly not supported on the established criteria drawn by experts and this lack of accuracy probably hits in the therapeutic result. The basis of the treatment of the SIADH is to correct its cause, water restriction, solutes (sodium chloride) and the use of vaptans in case of failure of the previous measures. (AU)

ABSTRACT

Resumen La gestación cornual, también conocida como intersticial, es una gestación ectópica infrecuente que ocurre en 1/2500 a 1/5000 de los embarazos cuando el embrión implanta en el trayecto intramiometrial de la porción proximal de la trompa. Puede debutar como shock hipovolémico en un 25% de los casos, conllevando una mortalidad de hasta un 2,5%. Mediante ecografía se encuentra un saco gestacional excéntrico y rodeado por una fina capa de miometrio. El tratamiento, en la mayoría de los casos, es quirúrgico, y el control de la hemostasia supone todo un reto. Se presentan dos casos clínicos de mujeres con diagnóstico de gestación intersticial en quienes se realizó exéresis por laparoscopia tras inyección de vasopresina, permitiendo así controlar el sangrado. En una de las pacientes se practicaron también puntos transfixivos transitorios en la arteria uterina y el ligamento útero-ovárico.


Abstract Cornual gestation, also known as interstitial, is a rare ectopic gestation that occurs in 1/2500 to 1/5000 of pregnancies when the embryo implants in the intramyometrial tract of the proximal tube. It can debut as hypovolemic shock in 25% of cases, leading to a mortality rate of up to 2.5%. Using ultrasound, we will find an eccentric gestational sac surrounded by a thin layer of myometrium. Treatment, in most cases, is surgical and control of hemostasis is a challenge. Two clinical cases are presented of women with a diagnosis of interstitial pregnancy in whom transient transfixive sutures were performed at the level of the uterine artery and uterine-ovarian ligament and injection of vasopressin prior to laparoscopic exeresis, thus allowing the bleeding to be controlled.

ABSTRACT

Introducció. L’holoprosencefàlia és una malformació congènita greu que compromet estructures cerebrals situades ala línia mitjana. Per la seva localització, l’hipotàlem i lahipòfisi són estructures afectades sovint en aquesta entitat. La seva disfunció pot provocar trastorns de l’homeòstasii endocrinopaties com l’adípsia i la diabetis insípida.Cas clínic. Es presenta el cas d’una nena de 6 anys diagnosticada d’holoprosencefàlia als 9 mesos de vida. Consulta per somnolència i febre de 48 hores d’evolució i enl’exploració presenta signes de deshidratació. La mare refereix que no reclama ingesta hídrica tot i trobar-se deshidratada. Analíticament destaca deshidratació hipernatrèmica greu amb disfunció renal. A les 72 hores d’ingrés,després d’haver corregit les diselectrolitèmies i amb lapacient normohidratada, reapareix la hipernatrèmia ambpoliúria i osmolalitat urinària disminuïda. Es fa un test dedesmopressina que confirma la sospita diagnòstica de dèficit d’hormona antidiürètica associat a adípsia. S’instauratractament amb desmopressina i restricció hídrica amb elqual s’assoleix un bon control hidroelectrolític que esmanté en controls posteriors.Comentaris. Els pacients amb holoprosencefàlia tenen riscde presentar endocrinopaties per disfunció hipotalamohipofisiària. Per aquest motiu cal buscar-les activament encas de presentar-se la clínica clàssica de poliúria, hipernatrèmia i hipoosmolalitat urinària. (AU)

Introduction. Holoprosencephaly is a severe developmental defectthat compromise midline brain structures. Due to their location,the hypothalamus and the hypophysis are frequently involvedin this illness. Their dysfunction can lead to homeostatic andendocrine disorders such as thirst disturbances and diabetesinsipidus.Case report. Herein we report the case of a 6-year-old girl who wasdiagnosed with holoprosencephaly at 9 months old. She presentedwith a 48-hours history of somnolence and fever with signs of dehydration on examination. Her mother stated that despite beingdehydrated, she did not demand water intake. Laboratory evaluation revealed a severe hypernatremic dehydration with renal impairment. Seventy-two hours after admission, having successfullyattained fluid and electrolyte correction, she presented hypernatremia with polyuria and urine hypoosmolality. A desmopressin testwas performed confirming the suspected diagnosis of antidiuretichormone deficiency and adipsia. She responded well to desmopressin treatment and fluid restriction with restoration of serumelectrolytes, which remained within acceptable limits at follow-up.Discussion. Children with holoprosencephaly are at risk for endocrine disorders related to hypothalamic-pituitary dysfunction. It isimportant to rule out these disturbances if they present with theclassic triad of hypernatremia, polyuria and urine hypoosmolality. (AU)

ABSTRACT

ABSTRACT Objective: To analyze the effects of the ice popsicle on vasopressin, osmolality, thirst intensity, and thirst discomfort. Method: This is a quasi-experimental, pre- and post-test study conducted in a laboratory. The sample consisted of nine healthy male volunteers, who received 2% hypertonic saline solution. Results: Popsicle intake did not result in a statistically significant reduction in vasopressin levels (F=0.876 and p=0.428). However, there was a reduction in the hormonal physiological profile of vasopressin from 7.1 pg/ml to 5.8 pg/ml after the first two interventions. Osmolality concentration changed from 270.65 to 286.51 mOsm/kg, with no statistical difference (F=2.207; p=0.09). Ice popsicles significantly reduced thirst intensity (F=10.00; p=0.001) and thirst discomfort (F=10.528; p <0.001). Conclusion: There was a reduction in thirst intensity and discomfort after the use of the 20 ml ice popsicle. There was no statistical difference for vasopressin and osmolality. However, there was a reduction in the hormonal physiological profile of vasopressin during 30 minutes of intervention.


RESUMEN Objetivo: Evaluar los efectos del picolé de hielo sobre el perfil hormonal de la vasopresina, la osmolaridad, y la intensidad y el malestar de la sed. Método: Estudio casi-experimental pre- y pos-test, realizado en laboratorio. Nueve varones voluntarios sanos recibieron solución salina endovenosa al 2% y un picolé de hielo de 20 ml cada 15 minutos. Resultados: Ingerir el picolé no derivó en una caída estadísticamente significativa del nivel de vasopresina (F=0,876 y p=0,428). Entretanto, se registró una reducción en el perfil hormonal de la vasopresina de 7,1 pg/ml a 5,8 pg/ml después de las dos intervenciones. La osmolaridad plasmática se modificó de 270,65 a 286,51 mOsm/kg sin diferencia estadística (F=2,207; p=0,09). Se registraron reducciones en la intensidad (F=10,00 y p= 0,001) y en el malestar de la sed (F= 10,528; p<0,001). Conclusión: Se registraron reducciones en la intensidad y el malestar de la sed después de la intervención. No hubo diferencia estadística para la vasopresina y la osmolaridad. De esta manera, se observa la reducción en el perfil fisiológico de la vasopresina durante los 30 minutos de la intervención.


RESUMO Objetivo: Avaliar efeitos do picolé de gelo sobre perfil hormonal de vasopressina, osmolaridade, intensidade e desconforto da sede. Método: Quase-experimental, pré e pós-teste, realizado em laboratório. Nove voluntários saudáveis receberam solução salina endovenosa 2% e um picolé de gelo 20 ml a cada 15 minutos. As variáveis foram coletadas em cinco momentos. Resultados: Ingestão do picolé não resultou queda estatisticamente significativa da vasopressina (F = 0,876 e p = 0,428). Houve redução no perfil hormonal da vasopressina de 7,1 pg/ml para 5,8 pg/ml após duas intervenções. Osmolaridade plasmática alterou de 270,65 para 286,51 mOsm/kg, sem diferença estatística (F=2,207; p= 0,09). Houve redução da intensidade (F=10,00 e p= 0,001) e desconforto da sede (F=10,528; p < 0,001). Conclusão: Houve redução na intensidade e desconforto da sede. Não houve diferença estatística para vasopressina e osmolaridade. Observou-se redução no perfil fisiológico da vasopressina durante 30 minutos de intervenção.

ABSTRACT

La diabetes insípida es el resultado de una secreción o acción reducidas de la hormona vasopresina, expresada clínicamente por un cuadro de poliuria-polidipsia. Los arbovirus pueden tener afinidad por el sistema nervioso y se ha demostrado que el Zika desencadena un trastorno autoinmune que ataca a las células nerviosas, lo que puede traer como consecuencia una diabetes insípida central. En la literatura médica nacional e internacional revisada no se reportan casos anteriores donde se vincule la diabetes insípida con el virus del Zika. Se presenta un caso a propósito de esta asociación: paciente femenina de 53 años, diagnosticada con infección por el virus del Zika dos semanas antes de comenzar con los síntomas sugestivos de diabetes insípida. El potencial neurotrópico del virus, así como los resultados en la resonancia magnética nuclear y la determinación de marcadores de autoinmunidad anti-ADNdc positivos, son elementos que apoyan la hipótesis de que la paciente presentó una posible hipofisitis autoinmune, como respuesta inflamatoria post-infección, desarrollando diabetes insípida central transitoria(AU)


Diabetes insipidus is the result of reduced secretion or action of the vasopressin hormone, which is clinically expressed by a polyuria-polydipsia picture. Arboviruses can have a nervous system affinity and Zika has been shown to trigger an autoimmune disorder that attacks nerve cells, which can result in central diabetes insipidus. The reviewed national and international medical literatures does not report previous cases linking diabetes insipidus with Zika virus. It is presented a case about this association: 53-year-old female patient diagnosed with Zika virus infection two weeks before starting symptoms suggestive of diabetes insipidus. The neurotropic potential of the virus, as well as the results in nuclear MRI and the determination of positive anti-ADNdc autoimmunity markers are elements that support the hypothesis that the patient had a possible autoimmune hypophysis, as a post-infection inflammatory response, developing transient central diabetes insipidus(AU)

ABSTRACT

RESUMEN Introducción: se sabe que las concentraciones plasmáticas de hormona antidiurética o vasopresina son más altas en las mujeres con dismenorrea primaria (DiPr) y podría ser causa de retención de agua con signos y síntomas concomitantes que agravan su cuadro clínico. La monoterapia con AINEs en ocasiones alcanza solo un alivio parcial porque no incide sobre la vasopresina. Objetivo: evaluar la eficacia y tolerabilidad del dexketoprofeno + pamabrom en la DiPr tomando como referencia el acetaminofén. Materiales y métodos: estudio doble ciego, controlado, randomizado, en pacientes con DiPr asignados al azar. Fueron aleatorizadas 172 pacientes, 86 en cada grupo 1) Grupo casos (DP): dexketoprofeno + pamabrom o 2) Grupo control (AC): acetaminofén. Se evaluó la evolución de la intensidad del dolor, el alivio del dolor, la gravedad de otros síntomas presentes y la satisfacción global del médico y paciente. Se registró las reacciones adversas. Resultados: la disminución de la intensidad del dolor, de los síntomas acompañantes y el alivio del dolor evaluados por la EVA, la PID, la SPID, el PAR y el TOTPAR respectivamente es mayor y más rápida de modo significativo en todos los tiempos para la combinación DP. Las reacciones adversas fueron mínimas. La satisfacción global de pacientes y médicos respecto al tratamiento es significativa a favor de la combinación DP. Conclusiones: dexketoprofeno + pamabrom es significativamente más eficaz y rápido en el control del dolor y otros síntomas presentes en la dismenorrea primaria que acetaminofén demostrando la validez de añadir un diurético suave a un AINE para incrementar su eficacia. El tratamiento DP es bien tolerado (AU).


ABSTRACT Background: It is known that plasma concentrations of antidiuretic hormone or vasopressin are higher in women with primary dysmenorrhea (DiPr) and could cause water retention with concomitant signs and symptoms that aggravate the illness. Monotherapy with NSAIDs sometimes achieves only partial relief because it does not affect vasopressin. Objective: The aim was to evaluate the efficacy and tolerability of dexketoprofen + pamabrom in DiPr taking as reference acetaminophen. Materials and methods: Double-blind, controlled, randomized study in patients with DiPr random to 1) Case group (PD): dexketoprofen + pamabrom or 2) Control group (CA): acetaminophen. The evolution of pain intensity, pain relief, severity of other present symptoms and overall satisfaction of the doctor and patient were evaluated. Adverse reactions were recorded. Results: 172 patients were randomized, 86 in each group. The decrease in pain intensity, accompanying symptoms and pain relief evaluated by VAS, PID, SPID, PAR and TOTPAR respectively is significantly greater and faster at all times for the combination DP. Adverse reactions were minimal. The overall satisfaction of patients and doctors regarding treatment is significant in favor of the DP combination. Conclusions: Dexketoprofen + pamabrom is significantly more effective and faster in the control of pain and other symptoms present in primary dysmenorrhea than acetaminophen demonstrating the validity of adding a mild diuretic to an NSAID to increase its effectiveness. DP treatment is well tolerated (AU).

ABSTRACT

La oxitocina (OXT) como la arginina-vasopresina (AVP) son dos hormonas primitivas secretadas por la hipófisis posterior. Sus receptores están mucho más ampliamente distribuidos en el organismo de lo que se pensaba originalmente, incluido el hueso. En los estudios preclínicos, la OXT ha mostrado ser anabólica para el hueso, promoviendo la osteogénesis sobre la adipogénesis y favoreciendo la actividad osteoblástica sobre la osteoclástica. Tanto los osteoblastos como los osteoclastos tienen receptores para la OXT, y los efectos de los estrógenos sobre la masa ósea en ratones está mediada por lo menos en parte por la OXT. El mecanismo preciso por el cual la activación de los receptores de oxitocina (OXTR) se traduce en un incremento de la formación ósea permanece poco claro. La AVP también podría afectar el esqueleto en forma directa. Dos de los receptores de la AVP, V1a y V2 están expresados en osteoblastos y osteoclastos. La inyección de AVP en ratones de tipo salvaje aumenta la formación osteoclastos que producen resorción y reduce los osteoblastos formadores de hueso. En forma opuesta, la exposición de precursores osteoblásticos a antagonistas de los receptores V1a o V2, incrementan la osteoblastogénesis, como también lo hace la deleción genética del receptor V1a. (AU)


Both oxytocin (OXT) and argininevasopressin (AVP) are primitive hormones secreted by the posterior pituitary gland. OXT receptors are much more widely distributed in the body than originally thought, including in bone. In preclinical studies, OXT has been shown to be anabolic for bone, promoting osteogenesis over adipogenesis and favoring osteoblastic over osteoclastic activity. Both osteoblasts and osteoclasts have receptors for OXT, and the effects of estrogen on bone mass in mice is mediated at least in part by OXT. The precise mechanism by which the activation of oxytocin receptors (OXTRs) results in an increase in bone formation remains unclear. AVP could also have direct actions on the skeleton. The two AVP receptors, V1a and V2, are expressed in osteoblasts and osteoclasts. Injection of AVP in wild-type mice increases the formation of osteoclasts increasing bone resorption, and reduces bone-forming osteoblasts. On the contrary, the exposure of osteoblastic precursors to V1a and V2 antagonists increase osteoblastogenesis, the same as the genetic deletion of the V1a receptor. (AU)

ABSTRACT

RESUMEN Antecedentes: La incidencia de la diabetes insípida gestacional es aproximadamente 1/30.000 gestaciones. Objetivo: A propósito de un caso de diabetes insípida gestacional ocurrida en nuestra unidad, se decide comunicar y revisar la literatura referente a opciones de manejo y tratamiento del mismo. Caso clínico: Mujer de 38 años, primigesta de 32 semanas con clínica de poliuria y polidipsia con una ingesta hídrica diaria de hasta 7 litros. Tras realizar las pertinentes exploraciones complementarias y descartar otras patologías más frecuentes, se establece el diagnóstico de diabetes insípida gestacional. Conclusiones: La diabetes insípida gestacional es una entidad muy poco frecuente que puede desencadenar en un estado de deshidratación intensa con hipernatremia y su consecuente afectación neurológica. Es importante el diagnóstico precoz para evitar las complicaciones tanto a nivel materno como fetal, así como realizar un manejo multidisciplinar de esta patología.


ABSTRACT Background: The incidence of diabetes insipidus during pregnancy is approximately 1 in 30,000 pregnancies. Objective: We herein report a case of a patient with gestational diabetes insipidus occurring in our unit. We decided to communicate the case and review the literature regarding management and treatment options. Case report: A 38-year-old woman at 32 week of pregnancy with polyuria, polydipsia, and daily water intake of up to 7 liters. After performing the complementary tests and ruling out other more frequent conditions, the diagnosis of gestational diabetes insipidus was established. Conclusion: Gestational diabetes insipidus is a very rare entity that can cause a state of intense dehydration with hypernatremia and its consequent neurological impairment. Early detection is important in order to avoid complications of both mother and fetus, as well as to carry out a multidisciplinary management of this condition.

ABSTRACT

Resumen: Introducción: Los pacientes politraumatizados desarrollan una respuesta inflamatoria sistémica y sucesos quimiotácticos similares a los observados en procesos infecciosos; de éstos los que además presentan TCE severo requieren mantenimiento de presión arterial media (TAM) ≥ 90 mmHg, lo que conlleva la necesidad de dosis altas de vasopresores. Objetivo: Evaluar los efectos hemodinámicos de la administración de norepinefrina/vasopresina (grupo experimental) versus norepinefrina (grupo control) en pacientes politraumatizados con traumatismo craneoencefálico severo hemodinámicamente inestables. Material y métodos: Ensayo clínico controlado, no aleatorizado, abierto y de grupos paralelos. Resultados: Se obtuvo una muestra homogénea de 20 pacientes; ambos grupos mantuvieron las medianas de TAM similares [experimental 90 versus control 93 mmHg, p = 0.516]. Los efectos hemodinámicos a favor del grupo experimental fueron: presión arterial sistólica (PAS) [primera hora, p = .041], frecuencia cardiaca (FC) [primera hora p = .029] así como lactato [hora 5, p = .015]. En cuanto al balance hídrico, la mediana del grupo control fue de +1,516 mL versus +553 mL del grupo experimental [p = 0.579]. Conclusión: No existe diferencia significativa en la TAM en la reanimación y neuroprotección de ambos grupos. Hubo mejoría estadísticamente significativa en la TAS y FC en la primera hora a favor del grupo experimental.


Abstract: Introduction: The politraumatized patients develop a systemic inflammatory response and quimiotaxis cascade like the infectious diseases; from this kind of patients, those with severe traumatic brain injury, need to hold medium arterial pressure ≥ 90 mmHg, that triggers high doses of vasopressor. Objective: Evaluate hemodynamic repercussion, of infusion Vasopressin/Norepinephrine (experimental group) vs Norepinephrine (control group) in politraumatized patients with severe traumatic brain injury whom present hemodynamic instability. Material and methods: Controlled, non randomized and open trial, with parallel groups. Results: We got a standardized sample of 20 patients; both groups had the same median of mean arterial pressure (MAP) [experimental group 90 versus control group 93 mmHg, p = 0.516]. There were better hemodynamic effect in experimental group, in systolic arterial pressure (SAP) [first hour, p = .041], heart rate (HR) [first hour p = .029], and lactate [hour 5, p = .015]. The fluid balance's median in control group was +1,516 mL versus +553 mL in experimental group [p = 0.579]. Conclusion: There was no significant difference in MAP of both groups, in reanimation period either neurological protection therapy. There was statistically significant improvement in SAP and HR, in experimental group.

ABSTRACT

Introducción. En diversos modelos animales, incluido el de la separación materna durante la lactancia, se ha demostrado que las experiencias tempranas adversas, como el maltrato, el abandono materno y el estrés psicosocial, pueden favorecer el desarrollo de algunas enfermedades mentales, pero no se han descrito completamente varios de los cambios que se producen en el sistema neuroendocrino. Objetivo. Determinar si la separación materna durante la lactancia modificaba los niveles basales de neurohormonas como la corticosterona, la corticotropina (ACTH), la oxitocina y la vasopresina (ADH), en ratas jóvenes (35 días) y adultas (90 días). Materiales y métodos. Se separaron ratas Wistar de sus madres durante dos periodos de tres horas diarias a lo largo de los 21 días de lactancia. A los 35 y 90 días se tomaron muestras de los grupos de las ratas de control y de las separadas de la madre, para obtener el suero y posteriormente medir cada una de las hormonas mediante un ensayo inmunoenzimático. Resultados. Las concentraciones de corticosterona fueron mayores en las hembras adultas de control que en el resto de los grupos, y menores en los machos adultos de control. Las de ACTH fueron mayores en los machos y hembras jóvenes separadas de la madre que en los grupos de adultos. Los niveles de oxitocina fueron significativamente mayores en las hembras adultas separadas de la madre que en los otros grupos y significativamente menores en los machos adultos. En cuanto a la vasopresina, los grupos separados de la madre tuvieron concentraciones menores, en comparación con los grupos de jóvenes y adultos de control. Conclusiones. Estos resultados muestran que el estrés temprano al que fueron sometidas las ratas, produjo cambios en las respuestas del eje hipotálamo-hipófisis-suprarrenal, las cuales variaron según el sexo y la edad.


Introduction: Work with different animal models including that of maternal separation during nursing has shown that early adverse experiences such as abuse, maternal abandonment and psychosocial stress may favor the development of various psychopathologies. However, several neuroendocrine changes have not been completely described yet. Objective: To establish whether maternal separation during nursing modifies the basal levels of neurohormones such as corticosterone, ACTH, oxytocin and vasopressin in juvenile and adult rats (aged 35 and 90 days, respectively). Materials and methods: Wistar rats were separated from their mothers for two periods of 3 hours per day during the 21 days of nursing. Once these rats had reached 35 and then 90 days of age, blood samples were taken from both the separated and control groups to obtain serum for immunoenzymatic assays and measure the levels of each of the hormones. Results: Concentrations of corticosterone were higher in control adult females in comparison with the rest of the groups and lower in the control adult males. Those of ACTH were higher in the separated young males and females than in the adult groups. Oxytocin levels were significantly higher in the separated adult females in comparison with the other groups and significantly lower in the adult males. With respect to vasopressin, the separated groups had lower concentrations than the young and adult control groups. Conclusions: These results show that the early stress to which rats were submitted produced changes in the basal responses of the hypothalamic-pituitary-adrenal axis, that these responses were distinct in males and females and that they also differed according to age.

ABSTRACT

The Advanced Cardiac Life Support proposes the use of vasopressor drugs cardiopulmonary resuscitation, with the primary purpose of effectively and early restoration of spontaneous circulation. However, the increased return of spontaneous circulation with vasopressors has not improved neurological outcome at hospital discharge. Adrenaline has traditionally been the main tool of the cardiopulmonary resuscitation guidelines despite the lack of conclusive scientific evidence. Therefore other alternatives were considered at experimental level that has have failed to overcome the clinical results of this drug. In contrast to progress on the standardized management of cardiopulmonary resuscitation, the controversy regarding the effectiveness of vasopressor therapy remains open in the last years due to lack of clinical data to support their usefulness.


El soporte vital avanzado propone el uso de vasopresores durante la resucitación cardiopulmonar, con la finalidad primordial de reestablecer de manera precoz y efectiva la circulación espontánea. Sin embargo, el aumento del retorno a la circulación espontánea asociada a los vasopresores no ha demostrado una mejoría en el pronóstico neurológico al alta hospitalaria. La adrenalina, ha sido tradicionalmente la herramienta principal de las guías de resucitación cardiopulmonar pese a la falta de evidencia científica concluyente. Por ello se han planteado otras alternativas a nivel experimental que no han logrado superar los resultados de este fármaco a nivel clínico. En contraste con los avances respecto al manejo estandarizado de la resucitación cardiopulmonar, el debate con respecto a la efectividad de la terapia vasopresora se mantiene abierto en los últimos años dada la falta de datos clínicos que corroboren su real utilidad.
