Hypertonic saline has been used for the treatment of hyponatremia for nearly a century. There is now general consensus that hypertonic saline should be used in patients with hyponatremia associated with moderate or severe symptoms to prevent neurological complications. However, much less agreement exists among experts regarding other aspects of its use. Should hypertonic saline be administered as a bolus injection or continuous infusion? What is the appropriate dose? Is a central venous line necessary? Should desmopressin be used concomitantly and for how long? This article considers these important questions, briefly explores the historical origins of hypertonic saline use for hyponatremia, and reviews recent evidence behind its indications, dosing, administration modality and route, combined use with desmopressin to prevent rapid correction of serum sodium, and other considerations such as the need and degree for fluid restriction. The authors conclude by offering some practical recommendations for the use of hypertonic saline.

Review
CONTEXT
Enuresis is a common and possibly underestimated condition. While 5-10% of school-aged children suffer from the condition, a lack of background knowledge may impede timely child-adapted and successful therapy.
OBJECTIVE
To provide a comprehensive overview of the pathophysiology, diagnosis, and treatment of enuresis.
EVIDENCE ACQUISITION
Guideline and position papers from the European Society of Pediatric Urology, the European Association of Urology, and the International Children's Continence Society were acquired. PubMed was searched for literature on enuresis, and all papers published in the last 5 yr were considered. The most relevant information from the papers with the highest level of evidence was extracted and incorporated into the review.
EVIDENCE SYNTHESIS
An altered antidiuretic hormone profile, arousal failure, and delayed bladder maturation are the main pathophysiological factors in primary enuresis. Coexisting constipation, obstructive airway disease, attention deficit hyperactivity disorder, obesity, and genetic preconditions influence its prevalence. Diagnosis relies on history-taking and simple noninvasive examinations to differentiate monosymptomatic enuresis and patients with daytime symptoms. It is essential to exclude daytime voiding symptoms, overactive bladder, dysfunctional voiding, and urinary tract infections. Further imaging is indicated in complex cases with a suspicion of underlying congenital malformations or systemic or endocrine diseases and in children refractory to initial therapy. In secondary enuresis, psychological causes should also be taken into consideration. While desmopressin melt tablets and alarm systems constitute the mainstays of treatment in monosymptomatic enuresis, anticholinergics and urotherapy play an additional role in nonmonosymptomatic enuresis. For therapy-refractory cases, after a thorough re-investigation to identify any missed comorbidities and anatomical or functional causes of enuresis, combination therapy and stationary urotherapy might be promising options.
CONCLUSIONS
While enuresis seems to be an often underestimated condition in terms of the suffering that children and their families, there are efficacious therapy options once a correct and full diagnosis is made.
PATIENT SUMMARY
This article reviews primary and secondary nocturnal enuresis, which is the medical term for the condition whereby children wet their beds regularly after their first birthday. We describe the background of enuresis,including its complex underlying mechanisms, as well as diagnosis and treatment in the light of current scientific publications. We conclude that while enuresis seems to be an often underestimated condition in terms of the suffering that children and their families may undergo, there are efficacious therapy options once a correct and full diagnosis is made.

Review
Diabetes insipidus and the syndrome of inappropriate antidiuretic hormone secretion lie at opposite ends of the spectrum of disordered renal handling of water. Whereas renal retention of water insidiously causes hypotonic hyponatremia in syndrome of inappropriate antidiuretic hormone secretion, diabetes insipidus may lead to free water loss, hypernatremia, and volume depletion. Hypernatremia and hyponatremia are associated with worse outcomes and longer intensive care stays. Moreover, pathologies causing polyuria and hyponatremia in patients in intensive care may be multiple, making diagnosis challenging. We provide an approach to the diagnosis and management of these conditions in intensive care patients.

Review
INTRODUCTION
Postural orthostatic tachycardia syndrome (POTS) is an increasingly well-recognized condition encountered in clinical practice. Diagnosis and treatment remain extremely challenging. The limited success of currently available therapies has laid the foundation for a number of experimental therapies.
AREAS COVERED
In this review, we will briefly outline the pathophysiology and clinical features of this syndrome, before moving on to its management, with a specific focus on experimental pharmacological therapies. Finally, we briefly discuss POTS related to the SARS CoV-2 (COVID-19) pandemic.
EXPERT OPINION
Despite tremendous advances, the diagnosis and management of POTS remains extremely challenging. The multitude of contributory mechanisms, which predominate to varying degrees in different patients further complicates management. Improved characterization of pathophysiological phenotypes is essential to individualize management. Lifestyle measures form the first line of therapy, followed by beta-blockers, ivabradine, fludrocortisone, and midodrine. Supplemental therapies such as iron, vitamin D and α lipoic acid are quite safe and a trial of their use is reasonable. The use of erythropoietin, IVIG, desmopressin, etc., are more specialized and nuanced alternatives. In recent years, interest has grown in the use of cardiac neuromodulation. Though preliminary, some of these therapies are quite promising.

Review
Enuresis is a common complaint in children, with a prevalence of around 15% at age 6 years. Evidence suggests that enuresis could affect neuropsychiatric development. The condition may represent an entire spectrum of underlying urological conditions. It is important to understand the difference between monosymptomatic and non-monosymptomatic enuresis. Primary monosymptomatic enuresis can be managed efficaciously with care in different settings, like primary care, specialist nursing, or paediatric specialists, while non-monosymptomatic enuresis requires more complex evaluation and treatment. The diagnosis, investigation, and management of the two types of enuresis are discussed in this review.

Central diabetes insipidus from a patient's perspective: management, psychological co-morbidities, and renaming of the condition: results from an international web-based survey.
BACKGROUND
Central diabetes insipidus is a rare neuroendocrine condition. Data on treatment-associated side-effects, psychological comorbidities, and incorrect management are scarce. The aim of this study was to investigate patients' perspectives on their disease.
METHODS
This study used a cross-sectional, web-based, anonymous survey, developed by endocrinologists and patient representatives, to collect the opinions of patients with central diabetes insipidus on management and complications of their disease, psychological comorbidities, degree of knowledge and awareness of the condition among health-care professionals, and renaming the disease to avoid confusion with diabetes mellitus (diabetes).
FINDINGS
Between Aug 23, 2021, and Feb 7, 2022, 1034 patients with central diabetes insipidus participated in the survey. 91 (9%) participants were children and adolescents (37 [41%] girls and 54 [59%] boys; median age 10 years [IQR 6-15]) and 943 (91%) were adults (757 [80%] women and 186 [20%] men]; median age 44 years [34-54]). 488 (47%) participants had isolated posterior pituitary dysfunction and 546 (53%) had combined anterior and posterior pituitary dysfunction. Main aetiologies were idiopathic (315 [30%] of 1034 participants) and tumours and cysts (pre-surgical 217 [21%]; post-surgical 254 [25%]). 260 (26%; 95% CI [0·23-0·29]) of 994 patients on desmopressin therapy had hyponatraemia leading to hospitalisation. Patients who routinely omitted or delayed desmopressin to allow intermittent aquaresis had a significantly lower prevalence of hyponatraemia compared with those not aware of this approach (odds ratio 0·55 [95% CI 0·39-0·77]; p=0·0006). Of patients who had to be hospitalised for any medical reason, 71 (13%; 95% CI 0·10-0·16) of 535 patients did not receive desmopressin while in a fasting state (nil by mouth) without intravenous fluid replacement and reported symptoms of dehydration. 660 (64%; 0·61-0·67) participants reported lower quality of life, and 369 (36%; 0·33-0·39) had psychological changes subjectively associated with their central diabetes insipidus. 823 (80%; 0·77-0·82) participants encountered a situation where central diabetes insipidus was confused with diabetes mellitus (diabetes) by health-care professionals. 884 (85%; 0·83-0·88) participants supported renaming the disease; the most favoured alternative names were vasopressin deficiency and arginine vasopressin deficiency.
INTERPRETATION
This is the largest survey of patients with central diabetes insipidus, reporting a high prevalence of treatment-associated side-effects, mismanagement during hospitalisation, psychological comorbidities, and a clear support for renaming the disease. Our data are the first to indicate the value of routinely omitting or delaying desmopressin.

BACKGROUND
The indirect water-deprivation test is the current reference standard for the diagnosis of diabetes insipidus. However, it is technically cumbersome to administer, and the results are often inaccurate. The current study compared the indirect water-deprivation test with direct detection of plasma copeptin, a precursor-derived surrogate of arginine vasopressin.
METHODS
From 2013 to 2017, we recruited 156 patients with hypotonic polyuria at 11 medical centers to undergo both water-deprivation and hypertonic saline infusion tests. In the latter test, plasma copeptin was measured when the plasma sodium level had increased to at least 150 mmol per liter after infusion of hypertonic saline. The primary outcome was the overall diagnostic accuracy of each test as compared with the final reference diagnosis, which was determined on the basis of medical history, test results, and treatment response, with copeptin levels masked.
RESULTS
A total of 144 patients underwent both tests. The final diagnosis was primary polydipsia in 82 patients (57%), central diabetes insipidus in 59 (41%), and nephrogenic diabetes insipidus in 3 (2%). Overall, among the 141 patients included in the analysis, the indirect water-deprivation test determined the correct diagnosis in 108 patients (diagnostic accuracy, 76.6%; 95% confidence interval [CI], 68.9 to 83.2), and the hypertonic saline infusion test (with a copeptin cutoff level of >4.9 pmol per liter) determined the correct diagnosis in 136 patients (96.5%; 95% CI, 92.1 to 98.6; P<0.001). The indirect water-deprivation test correctly distinguished primary polydipsia from partial central diabetes insipidus in 77 of 105 patients (73.3%; 95% CI, 63.9 to 81.2), and the hypertonic saline infusion test distinguished between the two conditions in 99 of 104 patients (95.2%; 95% CI, 89.4 to 98.1; adjusted P<0.001). One serious adverse event (desmopressin-induced hyponatremia that resulted in hospitalization) occurred during the water-deprivation test.
CONCLUSIONS
The direct measurement of hypertonic saline-stimulated plasma copeptin had greater diagnostic accuracy than the water-deprivation test in patients with hypotonic polyuria. (Funded by the Swiss National Foundation and others; ClinicalTrials.gov number, NCT01940614 .).

Review
Nocturia is a significantly underestimated disorder, resulting in general worsening of patients' quality of life, while morbidity and mortality are increasing. Several urologic and other pathologic causes can be described in the background including relatively severe conditions. Therefore, accurate evaluation and adequate treatment is recommended. In this review the authors summarize the international literature regarding nocturia. PubMed and ScienceDirect databases were accurately reviewed for the relevant information. Epidemiology, etiology, unfavourable effects, diagnosis and possible treatment options were analysed. They found that symptoms can be releaved by lifestyle changes and traditional therapy in several cases, but clinically significant improvement can be reached using desmopressin in patients suffering from nocturnal polyuria. The authors conclude that nocturia may have negative effects on patients' quality of life and also on the society. Early detection and proper treatment is essential. Orv.

Review
Nocturnal enuresis is a common problem that children may present with in a primary care setting. It is important to take a detailed history to rule out secondary causes; however, most cases are primary in nature. It is essential to demystify the problem and reassure parents by educating them that the episodes are nonvolitional and most children outgrow the problem over time. Behavioral interventions are considered first line and are most successful when the child is invested in succeeding. Interventions should be initiated with specific goals in mind. Medications are effective and should be used in conjunction with behavioral interventions.
