Abstract
OBJECTIVES The aim of this study was to evaluate the clinical profile and outcome of young infants presenting to the pediatric emergency department with hypernatremic dehydration. METHODS A prospective observational study was conducted at a tertiary care teaching hospital over a period of 18 months. All outborn sick young infants aged 2 months or younger who presented to the emergency department with symptoms and signs of possible sepsis and/or dehydration were screened, and those with hypernatremia were enrolled in the study. Those infants born at less than 37 weeks of gestation and gross congenital anomaly were excluded. Hypernatremic dehydration was defined as serum sodium levels (Se Na+)higher than 145 mEq/L. Variables used in the study were defined as per standard definitions. Acute kidney injury was defined and staged using serum creatinine as per modified neonatal Kidney Disease Improving Global Outcome guidelines. Clinical presentation, laboratory parameters, and comorbidities were compared among outcome groups (survived and died). RESULTS Of 1124 outborn young infants who met the eligibility criteria for screening, 63 were diagnosed to have hypernatremic dehydration and 55 were enrolled. The hospital-based period prevalence of hypernatremic dehydration in young infants was 4.89%. The median age of presentation was 17 days (10-30). Male-to-female ratio was 1.1:1. Seventy-three percent were first in birth order. Feeding pattern showed 61.8%, 30.9%, and 7.3% of infants were exclusively breastfed, top fed, and mixed fed, respectively. The median serum sodium at the time of admission was 160 (153.5-167) mg/dL. Three (5.5%) infants had mild, 39 (70.9%) had moderate, and 13 (23.6%) had severe hypernatremic dehydration. There was statistically significant correlation between median platelet count with severity of hypernatremic dehydration. The mean time taken to correct serum sodium level was 3.30 ± 1.60 days. The case fatality rate was 41.8%. Those who died had statistically more severe hypernatremic dehydration, acute kidney injury, sepsis, and need for ventilation. CONCLUSIONS Acute kidney injury stage 3, shock, and need for ventilation are associated with poor outcome in infants with hypernatremic dehydration.

Abstract
Hypernatremic dehydration in term newborns has steadily increased in incidence with increasing efforts to promote exclusive breastfeeding before hospital discharge, a key metric of the Baby-Friendly Hospital Initiative. The following report details a case of a term newborn infant who had evidence of poor intake while exclusively breastfeeding during his hospital stay that may not have been recognized by health care providers. The infant was discharged home and was subsequently found by the parents in cardiac arrest 12 h after discharge and was found to have hypernatremic dehydration. Although return of spontaneous circulation was achieved after fluid resuscitation, the infant sustained extensive hypoxic-ischemic brain injury due to cardiovascular collapse. Due to the infant’s extremely poor prognosis, life support was withdrawn at 19 days of age and the infant expired. This sentinel case demonstrates multiple pitfalls of current perceptions of normal vs. abnormal newborn feeding behavior, weight loss percentages, elimination patterns, and acceptable clinical thresholds believed to be safe for neonates. Newer data have shown that hypernatremia occurs commonly in healthy, term breastfed newborns at weight loss percentages previously deemed normal by most health professionals and hospital protocols. In-hospital strategies to prevent excessive weight loss and screening for hypernatremia in response to signs of inadequate feeding have the potential to prevent tens of thousands of readmissions for feeding complications a year, as well as hundreds of millions in health care costs.

Abstract
BACKGROUND Variable neurological manifestations and imaging findings have been described in children with severe hypernatremia. We aimed to describe the spectrum of neuroimaging changes in infants with severe hypernatremia. METHODS This retrospective study included infants with severe hypernatremia (serum sodium >160 mEq/L), abnormal neurological examination, and an abnormal magnetic resonance imaging (MRI) of the brain over a period of 2 years in a tertiary care hospital. Relevant clinical data, including the feeding practices, clinical features, complications, and biochemical and radiological parameters, were entered in a structured pro forma. MRI findings were classified as vascular (hemorrhages and cerebral sinus venous thrombosis), osmotic demyelination syndrome (pontine and extrapontine myelinolyses), and white matter changes. RESULTS The common clinical features in the neonates were poor feeding (n = 4) and decreased urine output (n = 4); the older infants presented with gastrointestinal losses (n = 5). All cases had dehydration with encephalopathy. The patterns of radiological injury were vascular (hemorrhages, n = 5 and venous thrombosis, n = 3), osmotic demyelination (n = 8), and white matter changes (n = 7). Coagulopathy was correlated with the vascular complications (r = 0.8, p < 0.0001); the degree of dehydration was correlated with the venous thrombosis (r = 0.7, p < 0.04) and acute kidney injury (r = 0.8, p < 0.001). Neurological sequelae were seen in four cases and correlated with hypernatremia (r = 0.6, p = 0.03) and hyperosmolarity (r = 0.6, p = 0.03). CONCLUSION Characteristic neuroimaging findings are vascular changes in the form of venous thrombosis and hemorrhages, osmotic demyelination and white matter tract injury, and/or mostly combinations of these findings. Severe hypernatremia and resulting hyperosmolarity frequently cause neurological sequelae in neonates and infants.

Abstract
Hypernatremic dehydration in neonates is a common condition in an exclusively breastfed infant but often underdiagnosed. Any newborn who has lost more than 10% of birthweight should be carefully evaluated and monitored for clinical features of dehydration. Efforts such as frequent follow-up for weight check, and formula supplementation, if needed, should be provided to a neonate at risk of developing complications of dehydration. Adequate lactation consultation, both inpatient and outpatient, should also be provided, especially to the primigravida mother. Here, we present a case of a neonate with severe hypernatremic dehydration caused by inadequate lactation in a primigravida mother, which resulted in cerebral venous sinus thrombosis leading to significant intracerebral hemorrhage. The infant suffered permanent neurologic damage and was sent home on technological devices (tracheostomy and gastrostomy tubes). Further, we provide a brief review of hypernatremic dehydration and sinus venous thrombosis in neonates.

Abstract
The Swedish Agency for Health Technology Assessment and Assesment of Social Services (SBU) is an independent national authority, tasked by the government with assessing methods used in health, medical and dental services and social service interventions from a broad perspective, covering medical, economic, ethical and social aspects. The language in SBU's reports are adjusted to a wide audience. SBU's Board of Directors has approved the conclusions in this report. The systematic review showed the following graded results: There is limited scientific evidence that the triad (Three components of a whole. The triad associated with SBS usually comprises subdural haematoma, retinal haemorrhages and encephalopathy.) and therefore, its components can be associated with traumatic shaking (low-quality evidence). There is insufficient scientific evidence on which to assess the diagnostic accuracy of the triad in identifying traumatic shaking (very low-quality evidence). Limited scientific evidence (low-quality evidence) represents a combined assessment of studies of high or moderate quality which disclose factors that markedly weaken the evidence. It is important to note that limited scientific evidence for the reliability of a method or an effect does not imply complete lack of scientific support. Insufficient scientific evidence (very low-quality evidence) represents either a lack of studies or situations when available studies are of low quality or show contradictory results. Evaluation of the evidence was not based on formal grading of the evidence according to GRADE but on an evaluation of the total scientific basis.

Abstract
The case of a continuous hemodialysis patient who died shortly after erroneous infusion with undiluted hypertonic solution is reported. Autopsy showed small parenchymal hemorrhages in all organs. Although producers take measures to prevent such errors by hospital staff, further steps are suggested for types of dialysis requiring reinfusion of large quantities of reinfusion hemodialysis solution.

Abstract
OBJECTIVES The aim of this study was to reveal the frequency, presenting complaints, risk factors, complications, and ways for prevention of hypernatremic dehydration (HD) among term breastfed infants. METHODS The files of 159 breastfed term infants hospitalized because of HD between the years 2009 and 2014 were examined retrospectively in the Neonatal Intensive Care Unit of Sivas State Hospital, Turkey. The patients were classified according to serum sodium (Na) levels, group 1 (Na: 146-149 mEq/L, n = 68) and group 2 (Na ≥150 mEq/L, n = 91). RESULTS The most common complaint was fever (67.9%), and the most common physical finding was oral mucosal dryness (76%). There were positive correlations between serum Na levels and weight loss, hospital stay, admission age, admission to neonatal unit after discharge, serum urea levels, and body temperature (p < 0.05). The normalization period of Na levels was significantly longer (21.7 ± 8.8 versus 29.3 ± 17.8 hours, p = 0.03), and Na reduction rate was faster in group 2 (0.41 ± 0.3 versus 0.50 ± 0.3 mEq/L/hour, p = 0.02). Bradycardia was seen more commonly in group 2 (1.5% versus 16.5%, p = 0.002). CONCLUSIONS HD is a significant condition that should be treated appropriately to avoid serious complications.

Abstract
Hypernatremic dehydration is an important cause of intracranial hemorrhage. A possible association of intraventricular hemorrhage (IVH) with hypernatremia and/or high sodium intake has been suggested in preterm infants. To investigate the associations of early fluid and sodium intake or serum sodium concentrations with severe intraventricular hemorrhage (IVH) in extremely low birth weight (ELBW) infants, we reviewed the medical records of 169 inborn ELBW infants. Daily fluid and sodium intake, urine output, weight loss and serum sodium concentration during the first 4 days of life were obtained. Patients were divided into the severe IVH (grade 3/4) and the control (no or grade 1/2 IVH) group. The maximum serum sodium concentration and the incidence of hypernatremia did not differ between the two groups. Related to the fluid balance and sodium intake, the risk for severe IVH was strongly associated with total fluid and sodium intake during the initial four days of life. With respect to the fluids other than transfusion, severe IVH can be discriminated only by sodium intake but not by fluid intake. Large randomized controlled trials are required to clarify the causal relationship between the early sodium intake and severe IVH in ELBW infants.

Abstract
OBJECTIVES The aims of this study were to evaluate the prevalence, complications, and mortality of hypernatremic dehydration in neonates and to compare the effect of correction rate at 48 hours on mortality and on neurological outcome in the short term. METHODS This retrospective study was conducted between January 2007 and 2011 in the neonatal intensive care unit. Term neonates were included. The patients were grouped as follows: group 1 = 150 to 160 mmol/L, group 2 = 161 to 170 mmol/L and group 3 = 171 to 189 mmol/L. RESULTS Among 4280 neonates, 81 cases (1.8%) had hypernatremic dehydration. Groups 1, 2, and 3 consisted of 55, 23, and 3 patients, respectively. Mortality rates were as follows: 3.6%, 17.3%, and 66.6%. Mean serum sodium (Na) correction rates at 0 to 24 hours and 24 to 48 hours were 0.48 ± 0.2 versus 0.38 ± 0.31 mmol/L per hour (group 1) and 0.49 ± 0.21 versus 0.52 ± 0.28 mmol/L per hour (group 2), respectively. In 32 patients (58.1%) from group 1 and in 13 patients (56.5%) from group 2, correction rate of 0.5 mmol/L per hour or less was achieved. Twenty-two patients developed convulsions, which was the most common complication during therapy. Serum Na greater than 160 mmol/L at admission (odds ratio, 1.9; 95% confidence interval, 1.3-3.7) and serum Na correction rate of greater than 0.5 mmol/L per hour (odds ratio, 4.3; 95% confidence interval, 1.2-6.5) were independent risk factors for death or convulsion. There was a significant difference between groups 1 and 2 in Denver Developmental Screening Test II results (64.1% vs 30.7 %, P = 0.001). CONCLUSION Hypernatremic dehydration is an important problem that should be managed properly to avoid adverse outcomes.

Abstract
Hypernatremia has been causally linked with subdural hematoma (SDH), but more recently this has been called into question. Conversely, there is a well-established link between SDH and injury. We wish to examine the evidence base that hypernatremia in infants and young children causes SDH.We present 2 cases of children with severe hypernatremia whose intracranial contents were assessed by imaging in the first case and postmortem examination in the second. Neither demonstrated SDH. The first case was important as the hypernatremia was iatrogenic occurring in a controlled hospital environment.We also searched the literature from 1950 to 2007, collecting data on all reported cases of hypernatremia in children younger than 7 years whose intracranial contents were examined by imaging, surgery, and/or postmortem examination. Of 124 cases reported in 31 articles, 112 cases developed hypernatremia in the community, and 12 in the hospital. Subdural hematoma was demonstrated in 7 cases, all of which had developed hypernatremia in the community under circumstances that would make it difficult to exclude nonaccidental injury. None of the 12 cases that developed hypernatremia in a controlled hospital environment had SDH.The evidence base supporting the hypothesis that hypernatremia causes SDH is poor, depending on isolated reports with uncertain histories.

Abstract
MRI has become the most important modality in paediatric neuroimaging. It provides an excellent anatomical overview with good spatial and temporal resolution, allows investigations of the blood vessels, and - using technologies such as diffusion-weighted imaging and magnetic resonance spectroscopy - it allows quick and exact differentiation of ischemic, hypoxic, inflammatory, oncologic, traumatic and metabolic diseases. This review presents an overview of brain MRI in infants and children with suspected hypoxic-ischemic disease, metabolic disorders or (vascular) malformations, illustrating these issues by some MRI findings in selected important conditions and discussing some major clinical and pathophysiological aspects important for imaging.

Abstract
Severe neonatal hypernatremia is an important electrolyte disorder that has serious effects on the central nervous system, including brain edema, intracranial hemorrhage, hemorrhagic infarct, and thrombosis. Cerebral venous thrombosis is relatively rare in severe neonatal hypernatremic dehydration. The English literature contains only a few reports of the cranial radiological findings in severe neonatal hypernatremia. The authors report cranial MR venography findings of a newborn infant with severe hypernatremic dehydration. To the best of their knowledge, this is the first such report in the English literature.

Abstract
Data were prospectively obtained from exclusively breast-fed healthy term neonates at birth and from healthy mothers with no obstetric complication to determine risk factors for excess weight loss and hypernatremia in exclusively breast-fed infants. Thirty-four neonates with a weight loss > or = 10% were diagnosed between April 2001 and January 2005. Six of 18 infants who were eligible for the study had hypernatremia. Breast conditions associated with breast-feeding difficulties (P < 0.05), primiparity (P < 0.005), less than four stools (P < 0.001), pink diaper (P < 0.001), delay at initiation of first breast giving (P < 0.01), birth by cesarean section (P < 0.05), extra heater usage (P < 0.005), extra heater usage among mothers who had appropriate conditions associated with breast-feeding (P < 0.001), mean weight loss in neonates with pink diaper (P < 0.05), mean uric acid concentration in neonates with pink diaper (P < 0.0001), fever in hypernatremic neonates (P < 0.02), and the correlation of weight loss with both serum sodium and uric acid concentrations (P < 0.02) were determined. Excessive weight loss occurs in exclusively breast-fed infants and can be complicated by hypernatremia and other morbidities. Prompt initiation of breast-feeding after delivery and prompt intervention if problems occur with breast-feeding, in particular poor breast attachment, breast engorgement, delayed breast milk "coming in", and nipple problems will help promote successful breast-feeding. Careful follow-up of breast-feeding dyads after discharge from hospital, especially regarding infant weight, is important to help detect inadequate breast-feeding. Environmental factors such as heaters may exacerbate infant dehydration.

Abstract
Cerebral sinovenous thrombosis is a rare but potentially serious condition often occurring in children with nonspecific presenting features. Much remains to be learned about the long-term outcome of infants with cerebral sinovenous thrombosis. We report a series of four patients taken from a prospective database of neonates with sinovenous thrombosis who subsequently developed infantile spasms, three with hypsarrythmia on electroencephalography and one with multiple independent spike foci. The first patient presented at 2 weeks of age with hypernatremia, dehydration, and seizures. He was found to have extensive thrombosis and hemorrhagic infarction of the right basal ganglia. The second patient presented at 5 weeks of life and was found to have sagittal sinus thrombosis with bilateral intracranial hemorrhage. The third patient presented with seizures on day 1 of life and was found to have venous thrombosis involving the torcular, extending into the sagittal sinus. The fourth patient presented at 3 weeks with lethargy and seizures. He was diagnosed with bacterial meningitis and also had extensive sinus thrombosis. All patients developed infantile spasms at ages 9, 7, 11, and 10 months, respectively. This is the first report in the English literature describing infantile spasms as a possible outcome of sinovenous thrombosis in early infancy.

Abstract
OBJECTIVES To assess the incidence and complications of breastfeeding-associated hypernatremic dehydration among hospitalized neonates. STUDY DESIGN A retrospective study was conducted at Children's Hospital of Pittsburgh over a 5-year period, to identify otherwise healthy term and near-term (> or =35 weeks of gestation) breastfed neonates (<29 days of age) who were admitted with serum sodium concentrations of > or =150 mEq/L and no explanation for hypernatremia other than inadequate milk intake. RESULTS The incidence of breastfeeding-associated hypernatremic dehydration among 3718 consecutive term and near-term hospitalized neonates was 1.9%, occurring for 70 infants. These infants were born primarily to primiparous women (87%) who were discharged within 48 hours after birth (90%). The most common presenting symptom was jaundice (81%). Sixty-three percent of infants underwent sepsis evaluations with lumbar puncture. No infants had bacteremia or meningitis. Infants had hypernatremia of moderate severity (median: 153 mEq/L; range: 150-177 mEq/L), with a mean weight loss of 13.7%. Nonmetabolic complications occurred for 17% of infants, with the most common being apnea and/or bradycardia. There were no deaths. CONCLUSION Hypernatremic dehydration requiring hospitalization is common among breastfed neonates. Increased efforts are required to establish successful breastfeeding.

Abstract
Hyperkalaemia is a life-threatening electrolyte disorder that can occur in the first week of life in almost 50% of preterm infants with a birth weight less than 1000 g [extremely low birth weight (ELBW)]. Serum potassium values higher than 7 mmol x l-1 are associated with cardiac arrhythmias and an increased incidence of intraventricular haemorrhage and periventricular leucomalacia. Therapeutic options to treat this dangerous imbalance comprise calcium gluconate, insulin plus glucose, albuterol/salbutamol inhalation. Administration of cation-exchange resin such as sodium polystyrene sulphonate (Kayexalate) is effective in lowering plasma potassium, although complications following oral or rectal administration are reported in newborns. We describe two ELBW infants affected by hyperkalaemia, treated with Kayexalate, who developed serious hypernatraemia, that has never been reported before in preterm infants.

Abstract
As part of a population based regional review of all neonatal readmissions, the incidence of dehydration with hypernatraemia in exclusively breast fed infants was estimated. All readmissions to hospital in the first month of life during 1998 from a population of 32 015 live births were reviewed. Eight of 907 readmissions met the case definition, giving an incidence of at least 2.5 per 10 000 live births. Serum sodium at readmission varied from 150 to 175 mmol/l. One infant had convulsions. The sole explanation for hypernatraemia was unsuccessful breast feeding in all cases. The eight cases are compared with the 65 cases published in the literature since 1979. Presentation, incidence, risk factors, pathophysiology, treatment, and prevention are discussed.
