Objectives: Sodium disorders, the most common electrolyte disorders in hospitalized patients, are common in hospitalized patients with pneumonia. Numerous studies have shown that sodium abnormalities are independent risk factors for mortality, medical intensive care unit (ICU) admission, and prolonged hospital stay. The aim of the study was to investigate the prevalence of dysnatremia and the effect of dysnatremia on prognosis and mortality in critically ill COVID-19 patients. Methods: This retrospective study was performed between June 1, 2021, and July 30, 2021, in COVID-19 ICUs. 149 critically ill, laboratory-confirmed COVID-19 patients admitted to the ICU were included in the study. The collected data included demographic data, comorbidities, severity of illness, and laboratory tests (serum C-reactive protein, lymphocyte, ferritin, sodium, chloride, and potassium levels). The prognosis was evaluated in terms of mortality, need for mechanical ventilation, and length of ICU stay. Results: At ICU admission, hyponatremia was present in 33 (22.1%) patients, whereas hypernatremia was detected in 14 (9.5%) patients. 102 (68.4%) patients had normal sodium levels. The mortality rate for normonatremic, hyponatremic, and hypernatremic patients was 50.0%, 57.7%, and 78.6%, respectively. These results indicated a statistically significantly higher mortality rate in patients with baseline hypernatremia (p=0.05). Conclusion: Among critically ill COVID-19 patients in the ICU, dysnatremia was common at admission and hyponatremia was more common than hypernatremia. Hypernatremia was related to mortality. Admission sodium levels can be a predictor of mortality in COVID-19 patients who are critically ill. [ABSTRACT FROM AUTHOR]

Background: sodium disorders are the most common and least understood in patients with acute brain injury due to the major role played by the central nervous system in regulating sodium and water homeostasis, which can lead to serious complications and adverse outcomes, including death.Objective: to determine the hypernatremia contribution to mortality in patients with neurological conditions in critical state. Methods: longitudinal analytical observational study on 55 patients who were admitted to the acute care units at the Arnaldo Milián Castro University Hospital, between October 2020 and May 2022, regardless of the plasma sodium value upon admission to the service, as well as during their stay in the critical care units. Univariate and bivariate statistical methods were used in data analysis. Results: the average age was 60 ± 16 years. The most relevant diagnoses were intraparenchymal hemorrhage (56.37%), head trauma, and ischemic stroke (both 30%). Plasma sodium concentrations showed significant differences (pX2= 0.000), with the highest average at 24 hours of admission (174.2 ± 133.6) and the lowest at the 5th day (102.9 ± 72.9). There was a significant correlation between plasma sodium concentrations at admission, 24h and 72h with the state at discharge. In the individual bivariate analysis by period, there was only a significant relationship after 24 hours. In this period, hypernatremia contributed 1.78 times more to mortality than in those who did not have elevated sodium (OR=1.78 with CI: 1,39-3,4).Conclusions: hypernatremia in critically ill patients with neurological conditions is associated with increased mortality.

- Abstract
Introduction: hyperchloremia and hypernatremia are common complications in critically ill children and have been associated with the development of acute kidney injury (AKI) and mortality. Objective: to estimate the incidence of hyperchloremia and hypernatremia during the first 72 hours of admission to a pediatric intensive care unit (PICU), and to evaluate their association with AKI and mortality. Material and methods: prospective cohort study, conducted over a period of 15 months. Patients with disorders in plasma levels of chloride (Cl-) or sodium (Na+), as well as with AKI at the time of admission, were excluded. Values > 110 mEq/L Cl- and > 145 mEq/L Na+ were considered as hyperchloremia and hypernatremia, respectively. A sample size of 255 patients was calculated. Statistical analysis. Odds Ratio (OR) and 95% confidence intervals (95% CI) were calculated for bivariate and multivariate analyses. Results: among 241 patients, the incidence of hyperchloremia was 12.4% (n = 30), and of hypernatremia 18.6% (n = 45). The frequency of AKI was 35.6%, and mortality was 14.1%. In logistic regression analysis, hypernatremia was associated with AKI (OR 2.7, 95% CI 1.3-5.7, p < 0.006), but not with mortality. While hyperchloremia was not identified as a risk for AKI or death. Conclusions: hyperchloremia and hypernatremia are common in critically ill pediatric patients, but only hypernatremia seems to confer a higher risk of complications. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Coronavirus disease 2019 (COVID-19) has provoked one of the greatest health crises of our time, which is why risk stratification at the time of hospitalization is essential to identify in good time patients with high morbidity and mortality risk. Dysnatremia as an independent predictor of mortality in patients with COVID-19 has recently become relevant. Objective: To find out if there is an association of dysnatremia with 28-day mortality, and as secondary objectives, its association with hospital stay, invasive mechanical ventilation (IMV) requirement and presence of acute kidney injury (AKI) during hospital stay. Material and methods: Retrospective, descriptive and analytical cohort study. All consecutive patients of 16 years or older of any gender, admitted to a third level hospital from March 1, 2020 to March 2021, who have a diagnosis of COVID- 19 with positive PCR were included. Results: The study included a total of 722 patients. The prevalence of dysnatremia was as follows: 18 patients presented hypernatremia (2.49%) and 153 hyponatremia (21.19%). The presence of hypernatremia once sodium was corrected for glucose was associated with higher mortality (p < 0.05, OR 3.446; 95% CI 1.776-6.688), an increased probability of presenting AKI (p <0.05, OR 2.985; 95% CI 1.718-5.184) and a greater requirement for IMV (p < 0.05, OR 1.945; 95% CI 1.701-5.098). Conclusions: Hypernatremia was associated with higher mortality, higher risk of presenting AKI and the requirement for IMV during hospitalization. [ABSTRACT FROM AUTHOR]

- Abstract
BACKGROUND: Hypernatremic dehydration is observed in newborn with unsuccesfully lactaction, due to unbalanced water and electrolytes. Different methods to correct it, can cause complications. Since 2010, we use a standarized method to treat hipernatremia in infant newborns. AIM: To compare neurologic adverse outcome in newborn with hipernatremia in two different periods; before and after to use standarized treatment. METHODS: Retrospective, observational, cross-sectional and comparative study: before-after design, in neonates with hypernatremia treated with institutional standarized method. Clinical records of newborns between 2001 and 2021 with hipernatremia were reviewed. Group 1 (before) with patients from 2001 to 2010; 2011 was the implementation year and second group (after) from 2012 to 2021. Demographic, clinic, biochemical and treatment variables were obtained. χ2 and t test were used to compare outcomes between both groups. RESULTS: 242 cases were included: 79 in first group and 158 in second group. Five patients were not included in comparation because were treated in implementation year. Serum cretinine was different between groups: 3.6 mg/dl in group 1, and 2.5 mg/dL in second group (p=0.02); lost weight and serum sodium were similar. We found less neurologic anormalities, anormal EEG and combined adverse outcome at discharge in second group. CONCLUSION: Standarized treatment of neonatal hipernatremia allowed reduce neurologic adverse outcomes in infant newborn. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Adipsic diabetes insipidus is a rare condition secondary to injury to osmoreceptors in the anterior hypothalamic area. Only two cases have been published secondary to pituitary tumor surgery. Case report: A 43-year-old man, postoperative of a non-functioning pituitary macroadenoma invading the third ventricle and compressing the hypothalamus. Reoperated for headache and rhinorrhachia, developing diabetes insipidus in the postoperative period was discharged with 20 µg/day nasal desmopressin. He came again due to sensorial disorder and hypernatremia, managing to control with intravenous hydration and desmopressin. It presents with recurrence of hypernatremia every time intravenous hydration is suspended and taken orally. With high sodium levels, there is an absence of thirst. A diagnosis of adipsic diabetes insipidus is made, indicating supervised administration of water orally with favorable evolution. Conclusions: Adipsic diabetes insipidus is a rare variant of central diabetes insipidus caused by damage to osmoreceptors in the hypothalamus. It manifests with absence of perception of thirst, hypernatremia and polyuria. Its management is complex and requires strict control of the water balance and adherence to treatment.

BACKGROUND: Glucose changes are unknown in neonatal dehydration with hypernatremia. OBJECTIVE: Was to investigate glucose status in neonatal hypernatremic dehydration (NHD) and its correlation with NHD prognosis. MATERIAL AND METHODS: In this cohort study, serum glucose of 172 neonatal hypernatremic dehydration infants admitted to the Ghaem Hospital in Mashhad, Iran, was reviewed within the time frame of 2012 to 2017. The data were collected utilizing a questionnaire designed by the researchers to describe the characteristics of the mothers and neonates, as well as their laboratory and imaging study results. The neonatal hypernatremic dehydration infants were followed using the Denver Developmental Test II (DDT II) questionnaire at follow-up months 6, 12, 18, 24, 30, and 36. RESULTS: 134 infants (77.91%) had normal blood glucose levels and 38 infants (22.09%) had a hyperglycemic status. In both groups, the differences in infant age (p = 0.000), weight upon admission (p = 0.035), breastfeeding duration (p = 0.003), frequency of urination (p = 0.001), blood sugar (p = 0.000), sodium (p = 0.008), urea (p = 0.000), creatinine (p = 0.000), and pH upon admission (p = 0.002) were statistically significant. Developmental delays were higher in the neonatal hypernatremic dehydration group with hyperglycemia (p = 0.029). There was a significant correlation between sodium levels and blood sugar (p = 0.000). CONCLUSION: According to our study results, hyperglycemic neonatal hypernatremic dehydration infants had an older referral age; higher sodium, urea, and creatinine levels; lower weight upon admission; shorter breastfeeding duration; lower frequency of urination; and lower blood pH. Therefore, checking the blood sugar of infants with hypernatremia is recommended and high serum glucose is a poor prognosis criterion in infants with neonatal hypernatremic dehydration.

- Abstract
A hemorragia subaracnoidea é uma causa importante de morbidade e mortalidade. O objetivo do estudo foi determinar os preditivos de mortalidade entre os pacientes com hemorragia subaracnoidea internados em uma Unidade de Terapia Intensiva. Estudo retrospectivo de pacientes com hemorragia subaracnoidea internados na Unidade de Terapia Intensiva de nossa instituição de 2009 a 2015. Os dados foram coletados do banco de dados eletrônico da Unidade de Terapia Intensiva e de revisões dos prontuários dos pacientes. Incluímos no estudo 107 pacientes com hemorragia subaracnoidea. A ruptura de aneurisma foi a causa da hemorragia subaracnoidea em 76 pacientes (71%). A mortalidade geral foi de 40% (43 pacientes) e esteve significativamente associada ao choque séptico, desvio da linha média na tomografia computadorizada, transferência inter‐hospitalar, pneumonia por aspiração e hipernatremia durante as primeiras 72 horas de internação na Unidade de Terapia Intensiva. A análise multivariada dos pacientes com hemorragia subaracnoidea pós‐ruptura de aneurisma revelou que a mortalidade esteve significativamente associada ao choque séptico e hipernatremia nas primeiras 72 horas de permanência na Unidade de Terapia Intensiva, enquanto o tratamento precoce do aneurisma (clipagem ou embolização endovascular) nas primeiras 72 horas foi identificado como preditivo de um bom prognóstico. Os pacientes com hemorragia subaracnoidea transferidos apresentaram taxas menores de sobrevivência. Choque séptico e hipernatremia foram complicações importantes entre os pacientes gravemente enfermos com hemorragia subaracnoidea e foram associados ao aumento da mortalidade. Subarachnoid haemorrhage is an important cause of morbidity and mortality. The aim of the study was to determine predictors of mortality among patients with subarachnoid hemorrhage hospitalized in an Intensive Care Unit. This is a retrospective study of patients with subarachnoid hemorrhage admitted to the Intensive Care Unit of our institution during a 7 year period (2009–2015). Data were collected from the Intensive Care Unit computerized database and the patients' chart reviews. We included in the study 107 patients with subarachnoid haemorrhage. A ruptured aneurysm was the cause of subarachnoid haemorrhage in 76 (71%) patients. The overall mortality was 40% (43 patients), and was significantly associated with septic shock, midline shift on CT scan, inter‐hospital transfer, aspiration pneumonia and hypernatraemia during the first 72 hours of Intensive Care Unit stay. Multivariate analysis of patients with subarachnoid hemorrhage following an aneurysm rupture revealed that mortality was significantly associated with septic shock and hypernatremia during the first 72 hours of Intensive Care Unit stay, while early treatment of aneurysm (clipping or endovascular coiling) within the first 72 hours was identified as a predictor of a good prognosis. Transferred patients with subarachnoid haemorrhage had lower survival rates. Septic shock and hypernatraemia were important complications among critically ill patients with subarachnoid haemorrhage and were associated increased mortality. [ABSTRACT FROM AUTHOR]

Antecedentes y objetivos: Historicamente la deshidratación se ha asoaciado como un factor de riesgo y de deselnace funcional en la trombosis venosa cerebral sin embargo no existen parametros clínicos o bioquímicos para definir el estado de deshidratación, ni su relacion con el pronostico o recanalización. Metodos: Se llevó a cabo un estudio retrospectivo transversal de pacientes con diagnóstico de trombosis venosa cerebral (TVC) en el Instituto Nacional de Neurología y Neurocirugía en México. La selección de pacientes se realizó desde enero de 2015 hasta enero de 2022. La deshidratación se evaluó mediante la obtención del cociente BUN/creatinina >15, sodio > 145mEq y hematocrito > 45%. Se realizó una regresión lineal univariante y un modelo de regresión multivariante para evaluar la relación entre el cambio de BUN/Cr, sodio y hematocrito al momento del diagnostico de la TVC y los resultados de recanalización a 6 meses. Resultados: Se incluyeron 59 pacientes, 17 hombres (28.81%) y 41 mujeres (71.18%), con una edad promedio 43 años (+/-17). Después de ajustar los posibles factores de confusión, el análisis de regresión multivariable reveló que las asociaciones entre el aumento de BUN/Cr (OR 2.25), hipernatremia (OR 1.04) y hematocrito (OR 1.57), se relacionan con ausencia de recanalizacion (P <0,05) a los 6 meses. Conclusión: El aumento de BUN/Cr, hipernatremia y aumento del hematocrito en el momento de diagnostico de la TVC se correlaciona negativamente con recanalizacón a 6 meses. [ABSTRACT FROM AUTHOR]

La disnatremia (hiponatremia e hipernatremia) es frecuente en los pacientes que se encuentran en la unidad de cuidados intensivos (UCI) y puede aparecer durante su estadía. El objetivo de este trabajo fue presentar y discutir el caso clínico de un paciente adulto quien posterior a un accidente de tránsito es llevado a UCI, con hipernatremia persistente secundaria al tratamiento farmacológico y nutricional. El caso se trata de un paciente masculino de 36 años de edad quien es ingresado a la UCI posterior a presentar traumatismo craneoencefálico. Durante su estadía presenta trastornos hidroelectrolíticos, entre ellos hipernatremia persistente. Desde el momento de su ingreso se inicia hidratación con solución hipertónica, soporte nutricional parenteral y enteral. Tras 11 días en UCI con hipernatremia el grupo realiza una reunión con sus tratantes decidiendo hacer uso de un nuevo esquema de nutrición y utilizar agua libre de sodio. Luego de los cambios comenzó la mejoría del paciente y las cifras de sodio disminuyeron. La hipernatremia está asociada a un mal pronóstico; es más frecuente que aparezca en los pacientes durante su estadía en UCI debido al contenido de sodio en infusiones intravenosas, soluciones hipertónicas, el uso de diuréticos e hidrocortisona que pueden desencadenar hipernatremia iatrogénica. La hipernatremia es una condición que puede ser prevenida y tratada rápidamente en los pacientes críticos, a través de un trabajo multidisciplinario, para minimizar el tiempo de estadía en UCI y en el centro hospitalario, reduciendo así los costes de tratamiento y una curación más rápida del paciente.

ABSTRACT OBJECTIVE: To compare two electrolyte maintenance solutions in the postoperative period in children undergoing appendectomy, in relation to the occurrence of hyponatremia and water retention. METHODS: A randomized clinical study involving 50 pediatric patients undergoing appendectomy, who were randomized to receive 2,000 mL/m2/day of isotonic (Na 150 mEq/L or 0.9% NaCl) or hypotonic (Na 30 mEq/L NaCl or 0.18%) solution. Electrolytes, glucose, urea, and creatinine were measured at baseline, 24 h, and 48 h after surgery. Volume infused, diuresis, weight, and water balance were analyzed. RESULTS: Twenty-four patients had initial hyponatremia; in this group, 13 received hypotonic solution. Seventeen patients remained hyponatremic 48 h after surgery, of whom ten had received hypotonic solution. In both groups, sodium levels increased at 24 h (137.4 ± 2.2 and 137.0 ± 2.7 mmol/L), with no significant difference between them (p = 0.593). Sodium levels 48 h after surgery were 136.6 ± 2.7 and 136.2 ± 2.3 mmol/L in isotonic and hypotonic groups, respectively, with no significant difference. The infused volume and urine output did not differ between groups during the study. The water balance was higher in the period before surgery in patients who received hypotonic solution (p = 0.021). CONCLUSIONS: In the post-appendectomy period, the use of hypotonic solution (30 mEq/L, 0.18%) did not increase the risk of hyponatremia when compared to isotonic saline. The use of isotonic solution (150 mEq/L, 0.9%) did not favor hypernatremia in these patients. Children who received hypotonic solution showed higher cumulative fluid balance in the preoperative period.

La deshidratación hipernatrémica neonatal (DHN) es una enfermedad grave y se asocia con edema cerebral, hemorragia intracraneal y gangrena. El manejo de estos pacientes es controvertido por las complicaciones que se han reportado si la corrección de la natremia se lleva a cabo rápidamente. Se propone un protocolo para disminuir lentamente el sodio sérico. Metodología: Estudio prospectivo que incluyó a pacientes con Na sérico >150 mEq. Se manejaron con una carga rápida de solución salina y soluciones de rehidratación con 50 mEq de Na/L y glucosa al 5%. Se monitorizó el Na sérico a las 12 y las 24 horas. Resultados: Se ingresaron al estudio 51 pacientes, con una incidencia identificada de 10.2 casos por 1,000 recién nacidos vivos. El promedio de Na en el momento del ingreso fue de 158 mEq/l. El promedio de disminución de Na en las primeras 12 horas fue de 0.53 ± 0.08 mEq/l/h. En las siguientes 12 horas fue de 0.46 ± 0.09 mEq/l/h. No se presentaron alteraciones neurológicas en ningún paciente. Conclusiones: La rehidratación en el neonato con DHN con una o dos cargas de solución salina al 0.9% y el posterior manejo con soluciones con 50 mEq/l de Na y solución glucosada al 5% (“tercio normal”) fueron seguros para descender lentamente los niveles séricos de Na, aproximadamente, a 0.5 mEq/h.

Sodium is a very useful mineral and known in the kitchens of homes and restaurants around the world as salt, but its importance is not attributed only to the flavor it brings to food. This micronutrient, also known as a type of electrolyte, is essential for maintaining the functionality of the human body. There is a risk to the health of individuals when their levels in the body are inadequate. This study aimed to analyze the importance of knowledge and correct diagnosis of health professionals to provide optimal treatment for hospitalized patients. This is a cross-sectional and descriptive study, with qualitative and quantitative data, with a snowball methodology, where it was publicized on social media and so one candidate could invite another to respond to the survey. Data collection was carried out through the application of an online questionnaire (Google Forms), in order to try to understand and ascertain the knowledge of professionals working in Intensive Care Units (ICUs) regarding the diagnoses and behaviors when receiving patients with critical levels of sodium. The results obtained showed that there is little experience of time in the ICU, for a large portion of the sample, and that most hospitalized patients present a picture of hyponatremia. In addition, the most frequent diagnosis is made through laboratory analysis, where the recurrent approach is the administration of fluid volume. It is necessary to expand diagnostic strategies to implement adequate treatment procedures. El sodio es un mineral muy útil y conocido en las cocinas de hogares y restaurantes de todo el mundo como sal, pero su importancia no se atribuye solo al sabor que aporta a los alimentos. Este micronutriente, también conocido como tipo de electrolito, es fundamental para mantener la funcionalidad del cuerpo humano. Existe un riesgo para la salud de las personas cuando sus niveles en el cuerpo son inadecuados. Este estudio tuvo como objetivo analizar la importancia del conocimiento y correcto diagnóstico de los profesionales de la salud para brindar un tratamiento óptimo a los pacientes hospitalizados. Se trata de un estudio transversal y descriptivo, con datos cualitativos y cuantitativos, con una metodología de bola de nieve, donde se publicitó en las redes sociales para que un candidato pudiera invitar a otro a responder la encuesta. La recogida de datos se realizó mediante la aplicación de un cuestionario online (Google Forms), con el fin de intentar comprender y conocer el conocimiento de los profesionales que laboran en Unidades de Cuidados Intensivos (UCI) sobre los diagnósticos y comportamientos al recibir pacientes con niveles críticos de sodio. Los resultados obtenidos mostraron que existe poca experiencia de tiempo en UCI, para una gran parte de la muestra, y que la mayoría de los pacientes hospitalizados presentan un cuadro de hiponatremia. Además, el diagnóstico más frecuente se realiza mediante análisis de laboratorio, donde el abordaje recurrente es la administración de volumen de líquido. Es necesario ampliar las estrategias de diagnóstico para implementar procedimientos de tratamiento adecuados. O sódio é um mineral muito útil e conhecido nas cozinhas dos lares e restaurantes ao redor do mundo como o sal, mas sua importância não está atribuída apenas ao sabor que traz aos alimentos. Esse micronutriente, também conhecido como um tipo de eletrólito, é indispensável para manter a funcionalidade do corpo humano. Havendo risco à saúde dos indivíduos quando seus níveis no organismo estão inadequados. O presente estudo teve como objetivo analisar a importância do conhecimento e correto diagnóstico dos profissionais da saúde para proporcionar tratamento ideal a pacientes hospitalizados. Trata-se de um estudo do tipo transversal e descritivo, com dados qualitativos e quantitativos, com uma metodologia em bola de neve, onde foi divulgado em mídias sociais e assim um candidato podia convidar outro para responder à pesquisa. A coleta de dados foi feita por meio de aplicação de questionário online (Google Forms), com intuito de tentar compreender e averiguar o conhecimento dos profissionais que trabalham em Unidades de Terapia Intensiva (UTIs) frente aos diagnósticos e condutas quando recebem pacientes com níveis críticos de sódio. Os resultados obtidos observaram que há pouca experiência em tempo de UTI, por grande parcela da amostra, e que a maioria dos pacientes internados apresentam quadro de hiponatremia. Além disso, o diagnóstico mais frequente é feito por meio de análise laboratorial, onde a conduta recorrente é a administração de volume de líquido. Fazendo-se necessário a ampliação de estratégias de diagnóstico para implementação de adequados procedimentos nos tratamentos.

- Abstract
Objectives: To identify variables associated with hypernatremia in adult patients admitted in an internal medicine service in a general hospital in Lima, Peru. Methods: Case-control study of patients admitted in the Internal Medicine service of Hospital Cayetano Heredia during 2013. A sample size of 65 cases and controls, matched by date of admission and Glasgow coma scale, to obtain an OR of 3 with 80% power and 95% confidence was estimated. Results: Hypernatremia was associated with fever (p=0.013); tachypnea (p=0.030); level of consciousness (p=0.032); use of diuretics (p=0.017); presence of diarrhea (p=0.045) and use of hypertonic solutions (p<0.0001). Acute renal failure and sepsis showed association in the univariate analysis but not in the logistic regression analysis. Conclusions: This study showed that fever, tachypnea, level of consciousness, use of diuretics, diarrhea and use of hypertonic solutions were relevant to develop hospital-acquired hypernatremia.

Hypernatremia is a common electrolyte problem at the intensive care setting, with a prevalence that can reach up to 25%. It is associated with a longer hospital stay and is an independent risk factor for mortality. We report a case of hypernatremia of multifactorial origin in the intensive care setting, emphasizing the role of osmotic diuresis due to excessive urea generation, an underdiagnosed and a not well-known cause of hypernatremia. This scenario may occur in patients using high doses of corticosteroids, with gastrointestinal bleeding, under diets and hyperprotein supplements, and with hypercatabolism, especially during the recovery phase of renal injury. Through the present teaching case, we discuss a clinical approach to the diagnosis of urea-induced osmotic diuresis and hypernatremia, highlighting the utility of the electrolyte-free water clearance concept in understanding the development of hypernatremia. Resumo A hipernatremia é um distúrbio eletrolítico comum no ambiente de terapia intensiva, com uma prevalência que pode chegar a 25%. Está associada a maior tempo de internação hospitalar e é um fator de risco independente para a mortalidade. Este relato ilustra um caso de hipernatremia de origem multifatorial no ambiente de terapia intensiva. Destacaremos o papel da diurese osmótica por geração excessiva de ureia, uma causa de hipernatremia pouco conhecida e subdiagnosticada. Este cenário pode estar presente em pacientes em uso de elevadas doses de corticoides, com sangramento gastrointestinal, em uso de dietas e suplementos hiperproteicos e estado de hipercatabolismo, especialmente durante a fase de recuperação de injúria renal. A seguir, discutiremos uma abordagem clínica para o diagnóstico da hipernatremia secundária à diurese osmótica induzida por ureia, destacando a importância do conceito de clearance de água livre de eletrólitos nesse contexto.

RESUMEN El Sodio es uno de los principales cationes extracelulares que se encarga de controlar el volumen extracelular y la presión sanguínea. El Sodio ingresa al organismo de los alimentos y las bebidas y lo elimina principalmente en el sudor y en la orina. Una función renal intacta mantiene una concentración constante de Sodio, ajustando la cantidad eliminada en la orina; cuando la ingesta y la pérdida de Sodio no están en equilibrio, se altera la cantidad total de Sodio en el organismo. Estos cambios en las concentraciones de Sodio provocan trastornos del balance de agua. Tanto la hiponatremia (Na 145 mEq/L) causan principalmente síntomas neurológicos. La instauración de los síntomas relacionados con la hiponatremia está dada por la gravedad y rapidez del cambio de concentración plasmática del Sodio. En individuos sanos, la ingestión de agua no conduce a hiponatremia porque la liberación suprimida de hormona antidiurética (ADH) permite que el exceso de agua se excrete en una orina diluida. Esta revisión bibliográfica se basa en estudios y guías clínicas actualizadas, cuyo objetivo es facilitar de manera más resumida, práctica y esquemática la corrección de los trastornos del Sodio. ABSTRACT Sodium is one of the main extracellular cations that is responsible for controlling extracellular volume and blood pressure. Sodium enters the body from food and drink and is eliminated mainly in sweat and urine. An intact kidney function maintains a constant sodium concentration, adjusting the amount excreted in the urine. When sodium intake and loss are not in balance, the total amount of sodium in the body is altered. These changes in sodium concentrations cause disturbances in the water balance. Both hyponatremia (Na < 135 mEq/L) and hypernatremia (> 145 mEq/L) mainly cause neurological symptoms. The onset of symptoms related to hyponatremia is due to the severity and rapidity of the change in plasma sodium concentration. In healthy individuals, ingestion of water does not lead to hyponatremia because the suppressed release of antidiuretic hormone (ADH), allows excess water to be excreted in dilute urine. This bibliographic review is based on updated studies and clinical guidelines, the objective of which is to facilitate the correction of sodium disorders in a more summarized, practical and schematic way.

- Abstract
Introduction: Salt (NaCl) is a chemical compound widely used in everyday life and in a number of medical procedures. Case report: The paper presents a case of unintentional fatal poisoning with saltwater, resulting from improperly provided first aid in a subject who attempted suicide (overdose of medication), and consulted by forensic experts for potential medical malpractice. A 34-year-old woman drank about 10 glasses of water (2500 mL) with a significant amount of salt. There was no subsequent vomiting, but at first severe water-electrolyte imbalance (severe hypernatremia) occurred and, consequently, multiple intracranial haematomas formed, ultimately leading to death. Conclusion: This case illustrates the still existing lack of adequate awareness of the causes and consequences of severe water-electrolyte imbalance which may result from incorrect attempts to treat acute poisoning.

Diabetes insipidus is a pathology characterized by the elimination of large amounts of dilute urine. The antidiuretic hormone is responsible of water reabsorption in medullary collecting duct in the kidney. There are two main types of diabetes insipidus, on one hand the neurogenic or central diabetes insipidus and on the other hand the nephrogenic or secondary diabetes insipidus, depending on the level that is affected. Several drugs have been related to loss of renal concentrating mechanism, being the lithium one of them. We present a case report of a patient undergoing surgery for benign pyloric stenosis in pharmacological long-term maintenance treatment of bipolar disorder with lithium. During the intraoperative period the patient began with high urine output and diabetes insipidus was suspected., La diabetes insípida es una patología caracterizada por la eliminación de volúmenes muy elevados de orina diluida.

Podemos diferenciar dos variantes, la neurogénica o central y la nefrogénica o secundaria según el nivel que esté afectado. Varios fármacos han sido relacionados con la pérdida de la capacidad concentradora renal de la orina, siendo el litio uno de ellos. Presentamos el caso de una paciente sometida a intervención quirúrgica por estenosis benigna de píloro en tratamiento farmacológico con litio por trastorno bipolar que durante el periodo intraoperatorio comenzó con diuresis elevada sospechándose diabetes insípida.

INTRODUCCION: El trauma craneoencefálico severo es una patología frecuente, conlleva una morbimortalidad no despreciable. La hipernatremia podría considerarse un factor asociado a mal pronóstico con el fin de optimizar la terapéutica en el grupo de pacientes de alto riesgo. OBJETIVO: Determinar si la hipernatremia es un factor pronóstico de mortalidad en pacientes con trauma craneoencefálico en un hospital público que es centro de referencia local en trauma. MATERIAL Y MÉTODO: Se realizó muestreo no probabilístico de pacientes con trauma encefalocraneano severo, adultos, ambos sexos de la Unidad de Cuidados Intensivos del Hospital Regional Docente de Trujillo en el periodo del 2015–2018. RESULTADOS: La mortalidad en el grupo con y sin hipernatremia fue de 38% y 6% respectivamente (p=0,001). La diferencia de medias de la natremia entre el grupo con y sin mortalidad fue de 21,86 (IC 95% 18,2-25,5) (p=0,000). En el análisis multivariado encontramos a la hipernatremia con OR ajustado de 16,73 (IC 95% 1,96-142,82) (p=0,01). La curva ROC mostró un rendimiento adecuado para predecir la mortalidad, con un AUC de 0,878 (IC 95% 0,77-0,97) (p=0,000). CONCLUSIÓN: La hipernatremia es un factor pronóstico de mortalidad en pacientes con trauma encefalocraneano severo. INTRODUCTION: A severe traumatic brain injury is a frequent pathology, it implies a non-negligible morbidity and mortality. Hypernatremia could be considered a factor associated with poor prognosis in order to optimize treatment in the group of high-risk patients. OBJECTIVE: To determine if hypernatremia is a prognostic factor of mortality in patients with severe traumatic brain injury in a public hospital wich is a local reference center in trauma. MATERIAL AND METHOD: We performed a non-probabilistic sampling of adult patients of both sexes with severe traumatic brain injury from the Intensive Care Unit of the Hospital Regional Docente de Trujillo during the 2015–2018 period. RESULTS: Mortality in the group with and without hypernatremia was 38% and 6% respectively (p=0.001). The difference in natremia means values between the group with and without mortality was 21,86 (95% CI 18.2-25.5) (p=0.000). In the multivariate analysis, we found hypernatremia with adjusted OR of 16.73 (95% CI 1.96-142.82) (p=0.01). The ROC curve showed adequate performance to predict mortality, with an AUC 0.878 (95% CI 0.77-0.97) (p=0.00). CONCLUSION: Hypernatremia is a prognostic factor of mortality in patients with severe traumatic brain injury. Tesis

Objective: The literature indicates a single universal cut-off point for weight loss after birth for the risk of hypernatremia, without considering other factors. The aim of this study was to construct and internally validate cut-off points for the percentage weight loss associated with the risk of hypernatremia, taking into account risk factors. Methods: A prospective study with a three-day follow-up was conducted in 165 neonates with a gestational age ≥35 weeks. The main outcome variable was mild or moderate hypernatremia (serum sodium ≥ 145 mmol/L). Secondary variables (risk factors) were maternal and infant variables. A multivariate logistic regression model was constructed to predict hypernatremia, obtaining its probability and the optimal discriminant cut-off point for hypernatremia (receiver operating characteristic analysis). Based on this point, threshold weight loss values were obtained according to the other variables. These values were internally validated by bootstrapping. Results: There were 51 cases (30.9%) of hypernatremia. The mean percentage weight loss for hypernatremic infants was 8.6% and 6.0% for the rest. Associated variables in the multivariate model included greater weight loss, male gender, higher education level, multiparity, and cesarean delivery. The model had an area under the receiver operating characteristic curve of 0.84 (sensitivity = 77.6%; specificity = 73.2%). Similar values were obtained in the bootstrapping validation. The lowest percentage weight loss was 4.77%, for cesarean delivery in male infants of mothers with a higher education level. Conclusions: The weight loss percentage values depended on the type of delivery, parity, newborn gender, and level of maternal education. External studies are required to validate these values. Resumo: Objetivo: A literatura indica um único ponto de corte universal na perda de peso após o nascimento para risco de hipernatremia, sem considerar outros fatores. Nosso objetivo foi criar e validar internamente pontos de corte para o percentual de perda de peso associado ao risco de hipernatremia considerando fatores de risco. Métodos: Foi feito um estudo prospectivo que incluiu 165 neonatos com idade gestacional ≥ 35 semanas, acompanhados por três dias. A principal variável de resultado foi hipernatremia leve ou moderada (sódio sérico ≥ 145 mmol/L). As variáveis secundárias (fatores de risco) foram variáveis maternas e dos neonatos. Um modelo multivariado de regressão logística foi criado para diagnosticar hipernatremia, obteve sua probabilidade e o ponto de corte discriminativo ideal para hipernatremia (análise da Característica de Operação do Receptor). Com base nesse ponto, obtivemos então os valores limites de perda de peso de acordo com as outras variáveis. Esses valores foram internamente validados por. Resultados: Há 51 casos (30,9%) de hipernatremia. O percentual de perda de peso para neonatos hipernatrêmicos foi 8,6% e 6,0% para o restante. As variáveis associadas no modelo multivariado incluíram maior perda de peso, sexo masculino, maior nível de escolaridade, multiparidade e cesárea. O modelo apresentou uma área sob a curva da Característica de Operação do Receptor de 0,84 (sensibilidade = 77,6%; especificidade = 73,2%). Valores semelhantes foram obtidos na validação da bootstrapping. O menor percentual de perda de peso foi 4,77% para cesárea em neonatos do sexo masculino de mães com maior nível de escolaridade. Conclusões: Os valores percentuais de perda de peso dependem do tipo de parto, paridade, sexo do recém-nascido e nível de escolaridade materna. São necessários estudos externos para validar esses valores. Keywords: Newborn, Dehydration, Hypernatremia, Weight loss, Palavras-chave: Recém-nascido, Desidratação, Hipernatremia, Perda de peso

- Abstract
Polyuria is a common clinical condition characterized by a urine output that is inappropriately high (more than 3 L in 24 h) for the patient's blood pressure and plasma sodium levels. From a pathophysiological point of view, it is classified into two types: polyuria due to a greater excretion of solutes (urine osmolality >300 mOsm/L) or due to an inability to increase solute concentration (urine osmolality <150 mOsm/L). Sometimes both mechanisms can coexist (urine osmolality 150-300 mOsm/L). Polyuria is a diagnostic challenge and its proper treatment requires an evaluation of the medical record, determination of urine osmolality, estimation of free water clearance, use of water deprivation tests in aqueous polyuria, and measurement of electrolytes in blood and urine in the case of osmotic polyuria., (Copyright © 2021 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

Introdução: Disnatremias são os distúrbios eletrolíticos mais frequentemente observados na prática clínica. A prevalência geral de hipernatremia em Unidades de Terapia Intensiva de adultos é de 9% a 14,3% e sua ocorrência relaciona-se com importante aumento da morbimortalidade. Poucos estudos tratam da epidemiologia de hipernatremia na população pediátrica. Objetivos: Verificar a prevalência de hipernatremia e caracterizar suas relações com variáveis demográficas, clínicas e evolutivas em uma Unidade de Terapia Intensiva Pediátrica (UTIP). Métodos: Coorte retrospectiva realizada em uma UTIP de um hospital universitário entre janeiro de 2005 e dezembro de 2015. Os pacientes foram divididos em: isonatremia, sódio ≥ 135 mEq/L e ≤ 145 mEq/L, hiponatremia, sódio < 135 mEq/L, e hipernatremia, sódio > 145 mEq/L. Pacientes com hipernatremia foram classificados de acordo com a gravidade e o momento de detecção e comparados com aqueles com isonatremia segundo variáveis demográficas (sexo e idade), clínicas (diagnóstico principal de admissão e Pediatric Risk of Mortality - PRISM) e evolutivas (tempo de internação, tempo de ventilação mecânica invasiva (VMI) e mortalidade). Resultados: Das 2145 admissões analisadas, 299 (13,9%) apresentaram hipernatremia. Pacientes com hipernatremia apresentaram maior frequência de doença crônica complexa (91,7%; p = 0,000), maior PRISM (média = 15,2 / DP = 10,6; p = 0,000), maior tempo de internação (média = 16,6 dias / DP = 33,4; p = 0,000), maior tempo de VMI (média = 9,4 dias / DP = 16,3; p = 0,000) e maior mortalidade (22,1%; p = 0,000). Os principais diagnósticos observados nesses pacientes foram pós-operatórios de cirurgia cardíaca (33,8%), sepse (14,7%) e sofrimento cerebral difuso (13%). Houve predomínio de hipernatremia leve (72,6%) e hipernatremia à admissão (64%). Conclusões: Hipernatremia é relativamente frequente em UTIP e identificada principalmente à admissão. Além disso, apresentou impacto na morbidade e mostrou-se como um fator de risco independente de mortalidade. Introduction: Dysnatremias are the electrolyte disturbances most frequently observed in clinical practice. The general prevalence of hypernatremia in adult Intensive Care Units is 9% to 14.3% and its occurrence is related to a significant increase in morbidity and mortality. Few studies address the epidemiology of hypernatremia in the pediatric population. Objectives: Verify the prevalence of hypernatremia and to characterize its relationships with demographic, clinical and evolutionary variables in a Pediatric Intensive Care Unit (PICU). Methods: Retrospective cohort performed at a PICU of a university hospital between January 2005 and December 2015. The patients were divided in the following groups: without dysnatremia, sodium ≥ 135 mEq/L and ≤ 145 mEq/L, hyponatremia, sodium < 135 mEq/L, and hypernatremia, sodium > 145 mEq/L. Patients with hypernatremia were classified according to severity and timing of detection and compared to those without dysnatremia according to demographic variables (sex and age), clinical variables (main diagnosis of admission and Pediatric Risk of Mortality - PRISM) and evolutionary variables (PICU length of stay, time of invasive mechanical ventilation and mortality). Results: Of the 2145 admissions analyzed, 299 (13.9%) presented hypernatremia. Patients with hypernatremia presented a higher frequency of complex chronic disease (91.7%, p = 0.000), higher PRISM (mean = 15.2 / SD = 10.6, p = 0.000), longer PICU length of stay (mean = 16,6 days / SD = 33,4; p = 0,000), longer time of invasive mechanical ventilation (mean = 9.4 days / SD = 16.3, p = 0.000) and higher mortality (22.1%, p = 0.000). The main diagnoses observed in these patients were postoperative cardiac surgery (33.8%), sepsis (14.7%) and diffuse brain distress (13%). There was a predominance of mild hypernatremia (72.6%) and hypernatremia on admission (64%). Conclusions: Hypernatremia is relatively frequent in the PICU and is identified primarily on admission. Besides that, it had an impact on morbidity and was an independent risk factor for mortality. Dissertação (Mestrado)

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Introduction: During a critical period of gestation, when the fetus still does not produce thyroid hormones (HTs), the development of organs and systems depends on the adequate supply of HT of maternal origin. Deficiency in the delivery of these hormones affects fetal growth and compromises their adaptation to extrauterine life. With this, many physiological systems can be reprogrammed, like the system of regulating the body's hydrosaline balance. Objective: To investigate the repercussions of experimental gestational hypothyroidism (HGE) on the biological systems responsible for homeostasis of body fluids in the offspring. Material and Methods: HGE was induced by the addition of 0.02% methimazole (MTZ) in drinking water from the ninth day of gestation (9ºDG) until delivery. Male offspring (192 animals) were distributed into the following groups: offspring of euthyroid rats (PRE), hypothyroid (PRH) and hypothyroid with thyroxine replacement (T4) (PRT4), 48 rats per group of mothers; (n = 24 / group) and after saline overload (NaCl 2%) (n = 24 / group) for recording intake and excretion of Na + and water, as well as the pressure arterial (tail plethysmography) at 60 and 90 days postnatal (PND). In addition, the measurement of the concentration and excreted load of Na + and K + serum and urinary, respectively, and the hematocrit dosage. Protocol of approval in the UFS Animal Research Ethics Committee (CEPA / UFS): 53/2016. The results are expressed as mean ± standard error of the mean. Two-way ANOVA tests of repeated measurements and Bonferroni post-test were performed. The critical level was set at 5% (P

Introducción: la deshidratación hipernatrémica neonatal asociada al fallo en la instauración de la lactancia materna puede provocar importantes complicaciones e incluso la muerte. Existen pocos datos acerca de su magnitud en nuestro medio. Objetivos: conocer la incidencia y describir las características clínico-epidemiológicas asociadas. Material y métodos: estudio observacional retrospectivo en recién nacidos con diagnóstico de deshidratación hipernatrémica con Na>150 mEq/l que necesitaron ingreso hospitalario entre 2011 y 2017 en nuestra área sanitaria. Se excluyeron casos con patología de base o infección concomitante. Se recogieron datos demográficos, clínicos, analíticos, terapéuticos y evolutivos mediante revisión de historias clínicas y se realizó análisis estadístico posterior. Resultados: la población susceptible estimada fue de 41 084 recién nacidos. Cumplieron criterios 20 casos. Alimentación con lactancia materna exclusiva 19/20, primer hijo en 14/20 familias, con mediana de edad materna 34 años (rango intercuartílico: 31-37). Los motivos de consulta más frecuentes fueron pérdida de peso, ictericia e irritabilidad. La mediana de edad al ingreso fue de 5,5 días (rango intercuartílico: 3,3-9,8), con porcentaje de peso perdido 14,4% (rango intercuartílico: 10-17) y natremia mediana 157,25 mEq/L (rango intercuartílico: 152-157,8). La estancia media fue de 6,5 días (rango intercuartílico: 4-8,75), 2/20 precisaron cuidados intensivos. No registramos fallecimientos o complicaciones graves. Conclusiones: la incidencia global de la deshidratación hipernatrémica fue de 0,5 por cada 1000 recién nacidos/año en la población estudiada. Se relacionó con lactancia materna exclusiva, primiparidad y mayor edad materna. Con estos resultados, parece una medida oportuna informar sobre signos de alarma al alta de maternidad, así como realizar la primera revisión del bebé de forma precoz. Introduction: neonatal hypernatremic dehydration associated with failure in the establishment of breastfeeding instauration can cause significant complications and even death. There are few studies on its incidence in Spain. Objectives: our aim was to determine the incidence of this problem and describe the epidemiological and clinical features associated with it. Materials and methods: we conducted a retrospective observational study in newborns with a diagnosis of hypernatremic dehydration and serum sodium levels of less than 150 mEq/l that required hospitalization between 2011 and 2017 in our catchment area. We excluded patients with underlying conditions or concomitant infection. We collected data on epidemiological, clinical, laboratory, treatment and outcome variables through the review of health records, followed by their statistical analysis. Results: the estimated size of the susceptible population was 41 084 newborns. Twenty met the inclusion criteria. In this sample, 19/20 newborns were exclusively breastfed, 14/20 were the first-born child, and the median maternal age was 34 years (interquartile range: 31-37). The most frequent reasons for seeking care were weight loss, jaundice and irritability. The median age at admission was 5.5 days (interquartile range: 3.3-9.8), the percentage of birth weight lost was 14.4% (interquartile range: 10-17), and the median serum sodium level was 157.25 mEq/l (interquartile range: 152-157.8). The mean length of stay was 6.5 days (interquartile range: 4-8.75), and 2/20 newborns required intensive care. None of the patients died or had severe complications. Conclusions: we found an overall incidence of hypernatremic dehydration of 0.5 per 1000 live births per year in the population under study. We found an association with exclusive breastfeeding, primiparity and greater maternal age. In light of these results, it seems advisable to provide information on the warning signs at the time of discharge from the maternity ward, and to schedule the first checkup for the baby at an earlier time.

ResumenIntroducciónLa rabdomiólisis es una enfermedad poco frecuente en pediatría. El objetivo es presentar un paciente en el que se desarrolló secundario a una deshidratación hipernatrémica grave tras una diarrea aguda.Caso clínicoLactante de 11 meses que consultó por fiebre, vómitos, diarrea y anuria. Presentó convulsión tónico-clónica autolimitada. Ingresó en mal estado general, severamente deshidratado, con escasa reactividad. En las pruebas complementarias destacó acidosis metabólica grave, hipernatremia e insuficiencia renal prerrenal. Al tercer día apreció leve hipotonía axial y elevación de creatín fosfokinasa 75.076 UI/l, interpretado como rabdomiólisis. Se inició hiperhidratación y alcalinización sistémica, con buena respuesta clínica y bioquímica, siendo dado de alta sin secuelas motoras.ConclusionesLa hipernatremia grave está descrita como causa rara de rabdomiólisis e insuficiencia renal. En pacientes críticos es importante un alto índice de sospecha de rabdomiólisis y determinación seriada de la creatín fosfokinasa para su detección y tratamiento precoz.AbstractIntroductionRhabdomyolysis is a rare paediatric condition. The case is presented of a patient in whom this developed secondary to severe hypernatraemic dehydration following acute diarrhoea.Case reportInfant 11 months of age who presented with vomiting, fever, diarrhoea and anuria for 15hours. Parents reported adequate preparation of artificial formula and oral rehydration solution. He was admitted with malaise, severe dehydration signs and symptoms, cyanosis, and low reactivity. The laboratory tests highlighted severe metabolic acidosis, hypernatraemia and pre-renal kidney failure (Sodium [Na] plasma 181 mEq/L, urine density> 1030). He was managed in Intensive Care Unit with gradual clinical and renal function improvement. On the third day, slight axial hypotonia and elevated cell lysis enzymes (creatine phosphokinase 75,076 IU/L) were observed, interpreted as rhabdomyolysis. He was treated with intravenous rehydration up to 1.5 times the basal requirements, and he showed a good clinical and biochemical response, being discharged 12 days after admission without motor sequelae.ConclusionsSevere hypernatraemia is described as a rare cause of rhabdomyolysis and renal failure. In critically ill patients, it is important to have a high index of suspicion for rhabdomyolysis and performing serial determinations of creatine phosphokinase for early detection and treatment.

- Abstract
AIMS: To report the case of a newborn with glycerol kinase deficiency, in which an isolated mutation not yet described in the GK gene was identified.CASE DESCRIPTION: A neonate with 10 days of age was brought to the emergency department for refusal to feed with 24 hours of evolution. Physical examination showed a loss of 31% of birth weight and signs of dehydration. Laboratory tests revealed a metabolic acidosis with increased anion gap, creatinine 2.41 mg/dL, urea 306 mg/dL, hypernatremia (182 mEq/L), hyperkalemia (6.8 mEq/L), hyperchloremia (151 mEq/L), glutamic-oxalacetic transaminase 879 U/L, glutamic-pyruvic transaminase 243 U/L, triglycerides 725 mg/dL. Chromotagraphy of organic acids revealed hyperglycerolemia and glyceroluria compatible with glycerol kinase deficiency. The genetic study revealed a mutation not yet described: c.187T> C (p.S63P) as hemizygote status in the GK gene.CONCLUSIONS: The most frequent cause of hypernatremic dehydration in the neonatal period is maternal hypogalactia. In more severe cases of dehydration, other etiologies should be considered, including metabolic causes such as glycerol kinase deficiency. In this case a mutation not yet described in the GK gene was found., OBJETIVOS: Relatar o caso de um recém-nascido com deficiência de glicerol quinase, no qual foi identificada uma mutação isolada ainda não descrita no gene GK.DESCRIÇÃO DO CASO: Um recém-nascido com 10 dias de vida foi trazido ao serviço de urgência por recusa alimentar com 24 horas de evolução. Ao exame físico apresentava perda de 31% do peso de nascimento e sinais de desidratação. Os exames laboratoriais constataram presença de acidose metabólica com anion gap aumentado, creatinina 2,41 mg/dL, ureia 306 mg/dL, hipernatremia (182 mEq/L), hipercalemia (6,8 mEq/L), hipercloremia (151 mEq/L), transaminase glutâmico-oxalacética 879 U/L, transaminase glutâmico-pirúvica 243 U/L, triglicerídeos 725 mg/dL. A cromotagrafia de ácidos orgânicos revelou hiperglicerolemia e glicerolúria compatíveis com deficiência de glicerol quinase. O estudo genético revelou uma mutação ainda não descrita: c.187T>C (p.S63P) em hemizigotia no gene GK. CONCLUSÕES: A causa mais frequente de desidratação hipernatrêmica no período neonatal é a hipogalatia materna. Nos casos mais graves de desidratação outras etiologias devem ser consideradas, incluindo causas metabólicas como a deficiência de glicerol quinase. Neste caso foi encontrada uma mutação no gene GK ainda não descrita.

A hipertensão arterial é uma das patologias mais comuns que afetam a população. Dentre os fatores que podem propiciar a hipertensão o comportamento alimentar ganha destaque no que se referem aos hábitos alimentares não saudáveis presentes na dieta ocidental. Sendo assim, o presente trabalho procurou avaliar alguns aspectos dessa patologia em diversas situações, e os temas foram discutidos de forma separada em dois capítulos. No primeiro momento avaliou-se o efeito da dieta hiperlipídica materna sobre os parâmetros metabólicos e autonômicos na prole. Sabe-se que a obesidade induzida pela dieta materna pode modificar os caminhos regulatórios centrais do feto, principalmente a regulação em longo prazo do apetite, porém nenhum trabalho procurou avaliar a influência da dieta hiperlipídica (DH) materna sobre os parâmetros cardiovasculares e autonômicos na prole. Ratas Holtzman adultas (280 - 300 g) foram divididas em dois grupos. Um grupo recebeu dieta padrão (DP) e o outro grupo DH. Os animais tiveram acesso livre a DP ou DH durante 6 semanas prévias (período de pré-gestação) e durante período de gestação e lactação. Todos os filhotes foram desmamados após 21 dias de vida e tiveram livre acesso a DP. Após uma semana alguns filhotes e as mães foram submetidos ao teste glicêmico e posteriormente eutanasiadas para retirada de tecido adiposo e sangue. Os outros filhotes foram submetidos à preparação coração-bulbo-hipotálamo (in situ). A DH aumentou o tecido adiposo nas ratas, mas foi capaz de alterar apenas as concentrações metabólicas de triacilgliceróis nesses animais. Filhotes machos de mães com DH (FMDH) apresentaram aumento no tecido adiposo, aumento nos níveis de colesterol total e nos níveis de HDL. Filhotes machos de mães com DP (FMDP) apresentaram redução da atividade simpática após transecção pré-colicular. Esse efeito não foi observado nos FMDH. A infusão de KCN provocou aumentos similares entre FMDP e FMDH quanto à atividade abdominal (ABD), na frequência do nervo frênico (f PNA) e na atividade simpática torácica (SNA), porém, no grupo FMDH esse aumento na SNA foi menor. O KCN provocou um aumento na amplitude do nervo frênico (PNA) sendo maior em FMDH. A hipercapnia provocou nos filhotes um aumento na SNA, na ABD e na PNA e gerou uma diminuição na f PNA em ambos os grupos. A diminuição na f PNA foi mais acentuada em FMDH e o aumento da PNA foi maior em FMDH. A fenilefrina provocou nos dois grupos uma diminuição na SNA, na ABD e na PNA, e gerou um aumento na f PNA. A simpatoinibição foi maior em FMDH. Esses resultados sugerem que a DH materna durante desenvolvimento fetal provavelmente altera as conexões centrais na prole. No segundo momento avaliou-se os efeitos da ocitocina sobre a reatividade vascular e seu papel nas respostas induzidas pela hipernatremia. Sabe-se que alterações no volume e/ou na composição dos compartimentos extracelulares evocam várias respostas autonômicas, cardiovasculares e hormonais que atuam em conjunto para modular a excreção renal de água e sódio. Os principais ajustes vegetativos são: vasodilatação renal e secreção de ocitocina. A regulação da osmolaridade e do volume é fundamental para sobrevivência. Apesar do vasto conhecimento na área nenhum estudo avaliou a interação entre a atividade simpática renal e a secreção de ocitocina sobre as respostas renais e cardiovasculares induzidas pela sobrecarga de sódio. Ratos Wistar machos (280-350 g) foram anestesiados e instrumentalizados para implantação de cateteres na bexiga, na veia e na artéria femoral e também para medição da pressão arterial média (PAM) e fluxo sanguíneo renal (FSR). Em ratos anestesiados (n = 6), a infusão de OT (0,03 μg/kg, i.v.) induziu vasodilatação renal. Em experimentações ex vivo a OT causou relaxamento da artéria renal. O bloqueio dos receptores de OT (OTR) reduziu essas respostas à OT, indicando um efeito direto desse peptídeo em seu receptor nesta artéria. O bloqueio dos receptores de ocitocina e a desnervação renal reduziu a vasodilatação renal e natriurese induzida pela sobrecarga de sódio aguda e a combinação do antagonista de receptores de ocitocina e a desnervação renal aboliram completamente a vasodilatação renal e reduziram ainda mais a natriurese induzida pela hipernatremia. Estes resultados sugerem que a OT e os nervos renais estão envolvidos na vasodilatação renal e natriurese induzida por hipernatremia aguda. O amplo conhecimento na área e a compreensão dos mecanismos regulatórios ativados tanto durante a obesidade quanto durante hiperosmolaridade permite uma maior possibilidade de desenvolvimento de novas ferramentas terapêuticas para a prevenção e tratamento da hipertensão. Hypertension is the most common pathologies which affect population. Of the factors that can promote hypertension, food behavior is highlighted in relation to unhealthy eating habits present in western diet. Thus, present study sought to evaluate some aspects of this pathology in several situations, and themes were discussed separately in two chapters. In the first moment, effect of maternal hyperlipidic diet on metabolic and autonomic parameters in offspring was evaluated. It is known which obesity induced by maternal diet can modify central regulatory pathways of the fetus, mainly long-term regulation of appetite, but no work sought to evaluate the influence of the maternal hyperlipidic diet (HD) on cardiovascular and autonomic parameters in the offspring . Female Holtzman rats (280-300 g) were divided into two groups. One group received standard diet (SD) and other HD. The animals had free access to SD or HD for 6 weeks prior and during gestation and lactation period. All pups were weaned after 21 days of life and had free access to SD. After one week some offspring and mothers were submitted to glycemic test and later euthanized for removal of adipose tissue and blood. Other offspring were submitted to in situ preparation. DH increased adipose tissue in all females, but was able to change only metabolic triacylglycerols concentration. Offspring of HFD dams (OffHFD) showed an increase in adipose tissue and total cholesterol and HDL levels. Offspring of SD dams (OffSD) showed decrease in sympathetic activity after pre-colicular transection. This effect was not observed in males offspring of mothers with HFD (OffHFD). KCN infusion caused similar increases in abdominal activity (ABD), in phrenic nerve frequency (PNA f) and sympathetic activity (SNA), but in OffHFD this increase in SNA was smaller. KCN caused increase in phrenic nerve amplitude (PNA) and was higher in OffHFD. Hypercapnia resulted in increase in SNA, ABD and PNA and decrease in PNA f in both groups. The decrease in PNA f was more pronounced in OffHFD and increased PNA was higher in OffHFD. Phenylephrine caused in both groups decrease in SNA, ABD and PNA, and generated an increase in PNA f. The reduction of SNA was higher in OffHFD. These results suggest that maternal HFD during fetal development alters central connections in offspring. In second moment oxytocin effects on vascular reactivity and its role in hypernatremia-induced responses were evaluated. Changes in volume and/or extracellular compartments composition are known to evoke various autonomic, cardiovascular and hormonal responses that to modulate renal excretion of water and sodium. The main vegetative adjustments are: renal vasodilation and oxytocin secretion. Regulation of osmolarity and volume is critical for survival. Despite knowledge, no study evaluated interaction between renal sympathetic activity and oxytocin secretion on renal and cardiovascular responses induced by sodium overload. Male Wistar rats (280–350 g) were anesthetized with sodium thiopental (40 mg/kg, i.v.). Animals were also instrumented for measurement of mean arterial pressure (MAP) and renal blood flow (RBF). Renal vascular conductance (RVC) was calculated as the ratio of RBF by MAP. In anesthetized rats (n = 6), OT infusion (0.03 μg/kg, i.v.) induced renal vasodilation. Ex vivo experiments demonstrated that OT caused renal artery relaxation. Blockade of OT receptors (OTR) reduced these responses to OT, indicating a direct effect of this peptide on OTR on this artery. Hypertonic saline (3 M NaCl, 1.8 ml/kg b.wt., i.v.) was infused over 60 s. In sham rats (n=6), hypertonic saline induced renal vasodilation. The OXTR antagonist (AT; n=7) and renal denervation (RX) reduced the renal vasodilation induced by hypernatremia. Atosiban with renal denervation (RX+AT; n=7) completely abolished renal vasodilation induced by sodium overload. Intact rats excreted 51% of the injected sodium within 90 min. Natriuresis was slightly blunted by atosiban and renal denervation (42% and 42% of load, respectively), whereas atosiban with renal denervation reduced sodium excretion to 16% of the load. These results suggest that OT and renal nerves are involved in renal vasodilation and natriuresis induced by acute plasma hypernatremia. The understanding of regulatory mechanisms activated both during obesity and during hyperosmolarity allows greater possibility development new therapeutic tools for hypertension prevention and treatment.

Introducción: El trabajo de investigación sobre factores clínico epidemiológicos asociados a DHN en recién nacidos en el Hospital III EsSALUD Juliaca 2016 – 2018, surge de la observación en la práctica clínica, la morbilidad y complicaciones que presenta. Objetivo Específico: Determinar los factores clínico epidemiológicos asociados a DHN en los recién nacidos. Metodología: Tipo de estudio observacional, prospectivo, transversal con diseño de casos y controles. Con una muestra de 30 RN con diagnóstico de DHN Neonatal y 30 clínicamente sanos como grupo control. Resultados: Dentro de los factores epidemiológicos: Encontramos que según la edad materna un 43,3 % de RN proceden de madres que se encuentran entre 19 y 25 años de edad; un 76.7% recibió lactancia mixta, las madre reportan que amamantaron cada 2 horas a sus RN en un 83,3%; un 100% de madres con técnica de lactancia inadecuada; un 63,3% de RN reingresó dentro de los 2 a 5 días de nacido, en los factores clínicos: Se evidencia que un 46,7% tuvo una pérdida entre 6 a 9 % de peso; 50,0% presentó temperatura inferior a 37,4 °C. Un 43,3 % de RN tuvo valores de hipernatremia entre 155 y 164 mg /dl, 40,0 % entre 150 a 154 mg/dl, 10,0 % entre 165 a 175 mg/dl y 6 ,67 % mayor a 175mg/dl. Encontramos que un 86,7% mostró irritabilidad, un 6,7% hipertonía en extremidades y un 6,7% Irritabilidad, hipertonía en extremidades y convulsiones focalizadas, 53,3% muestra creatinina entre 0,9 a 1 mg/dl; 66,7% no presentó hiperbilirubinemia. Conclusiones: Los niveles de sodio en el rango de 155 a 164 mg/dl, con pérdida de peso en el rango de 6 - 9%. La técnica de lactancia materna y el grado de DHN del RN se correlación de manera positiva perfecta, la lactancia mixta se asocia a DHN a diferencia de otros estudios, la DHN del RN presenta una correlación significativa con la semiología neurológica.

Objetivo: Analizar el manejo de los pacientes con hiponatremia durante su estancia en un hospital privado de Costa Rica así como las razones específicas generadoras de dicha enfermedad, para mejorar el manejo de esta patología y sus complicaciones. Método: Estudio observacional, restrospectivo realizado en un hospital de 80 camas en el periodo entre enero 2014 y enero 2017. Se incluyeron todos los pacientes que al ingreso o durante su estancia presentaron valores de sodio menor o igual a 125 mEq/L. Los datos clínicos obtenidos se agruparon en cinco clasificaciones: tiempo de desarrollo de la hiponatremia, concentración plasmática de sodio, gravedad de los síntomas, osmolalidad plasmática y estado de volumen. Resultados: En el estudio se incluyeron 102 pacientes de los cuales un 96% presentaron hiponatremia previa a su ingreso al hospital. Los síntomas neurológicos estaban presentes en un 36% de los casos. La hipertensión arterial (HTA) y la diabetes fueron las comorbilidades más frecuentes (96% de los pacientes). Con respecto al manejo farmacoterapéutico ninguno de los pacientes recibió la cantidad de mEq sodio requerida y solamente dos de los pacientes recibieron una monitorización de los valores plasmáticos de sodio tal y como lo establecen las guías. Conclusiones: Se debe educar al personal hospitalario sobre la importancia de un manejo adecuado de la hiponatremia, sus posibles efectos adversos y la importancia de instaurar un tratamiento precoz con el fin de evitar daños irreversibles. Objective: To analyze the management of patients with hiponatremia during their stay in a private hospital in Costa Rica, as well as the specific reasons for This disease, to improve the management of this disease and its complications. Method: Obsevational, retrospective study performed in a hospital with 80 beds in the period between Januany 2014 and January 2017. All patients were included who, on admission or during their stay, had sodium values less than or equal to 125 mEq/L. The clinical data obtained were grouped into five classifications: time of development of hyponatremia, plasma concentration of sodium, severity of symptoms, plasma osmolality and volume status. Results: 102 patients were included in the study, of which 96% had hyponatremia prior to hospital admission. Neurological symptoms were present in 36% of cases. High blood pressure (HBP) and diabetes were the most frequent comorbidities (96% of patients). None of the patients received the amount of mEq sodium required and only two of the patients received a monitoring of plasma sodium values as established by the guidelines. Conclusions: Hospital staff should be educated on the importance of proper management of hiponatremia, its possible adverse effects and the importance of establishing early treatment in order to avoid irreversible damage.

Introducción: la deshidratación hipernatrémica neonatal asociada al fallo en la instauración de la lactancia materna puede provocar importantes complicaciones e incluso la muerte. Existen pocos datos acerca de su magnitud en nuestro medio. Objetivos: conocer la incidencia y describir las características clínico-epidemiológicas asociadas. Material y métodos: estudio observacional retrospectivo en recién nacidos con diagnóstico de deshidratación hipernatrémica con Na>150 mEq/l que necesitaron ingreso hospitalario entre 2011 y 2017 en nuestra área sanitaria. Se excluyeron casos con patología de base o infección concomitante. Se recogieron datos demográficos, clínicos, analíticos, terapéuticos y evolutivos mediante revisión de historias clínicas y se realizó análisis estadístico posterior. Resultados: la población susceptible estimada fue de 41 084 recién nacidos. Cumplieron criterios 20 casos. Alimentación con lactancia materna exclusiva 19/20, primer hijo en 14/20 familias, con mediana de edad materna 34 años (rango intercuartílico: 31-37). Los motivos de consulta más frecuentes fueron pérdida de peso, ictericia e irritabilidad. La mediana de edad al ingreso fue de 5,5 días (rango intercuartílico: 3,3-9,8), con porcentaje de peso perdido 14,4% (rango intercuartílico: 10-17) y natremia mediana 157,25 mEq/L (rango intercuartílico: 152-157,8). La estancia media fue de 6,5 días (rango intercuartílico: 4-8,75), 2/20 precisaron cuidados intensivos. No registramos fallecimientos o complicaciones graves. Conclusiones: la incidencia global de la deshidratación hipernatrémica fue de 0,5 por cada 1000 recién nacidos/año en la población estudiada. Se relacionó con lactancia materna exclusiva, primiparidad y mayor edad materna. Con estos resultados, parece una medida oportuna informar sobre signos de alarma al alta de maternidad, así como realizar la primera revisión del bebé de forma precoz.
