Abstract BackgroundCerebral salt wasting syndrome (CSWS) and Syndrome of Inappropriate Anti Diuretic Hormone secretion (SIADH) are the most common aetiological factors for developing hyponatremia following stroke. The differentiation of these two entities is crucial as the treatment options are completely different. Hence the knowledge on predictors of CSWS is important to make a more accurate diagnosis of CSWS. MethodsTwo hundred and fourty six patients with confirmed stroke were prospectively observed throughout the hospital stay in a tertiary referral center in Sri Lanka to identify the possible predictors of CSWS. Hyponatremia was defined as serum Na+ level less than 131mmo/l. Serum osmolality, urine osmolality, urinary Na+, serum cortisol and thyroid function tests were performed on all the hyponatremic patients. Differentiation of the CSWS and SIADH was based on physical examination findings and laboratory parameters. ResultsThe incidence of hyponatremia in our study population was 19.1% (95% Confidence Interval 14.39-24.58). The majority of patients (24, 51%) were attributed to CSWS. SIADH group comprised of 17 (36.2%) patients and 6 (12.7%) patients had other undetermined causes. There was a significant statistical difference between the aetiologies of hyponatremia and laboratory investigations like urinary Na+, urinary osmolality and serum osmolality. Demographic characteristics, comorbidities, imaging findings and clinical parameters like systolic blood pressure, diastolic blood pressure, on admission GCS were considered in the multivariable logistic regression model and the overall model was not significant. Conclusion The incidence of CSWS is higher than the incidence of SIADH. The demographic characteristics, comorbidities, imaging and clinical parameters like blood pressure, on admission GCS could not predict the occurrence of CSWS

We report the first case series of 14 children with intracranial germ cell tumour (iGCT) and concomitant central diabetes insipidus (DI), who developed hyponatremia secondary to renal salt wasting syndrome (RSWS) following the administration of carboplatin. Clinicians prescribing platinum-based chemotherapy for this group of patients should be alert to the risk of RSWS. Regular monitoring should be performed as hyponatraemia can be asymptomatic until it is severe.

Electrolyte imbalance is an often incident in patients underwent neurosurgery and it potentially induces secondary brain injury, leading to a worse outcome, despite successful surgery. Diabetes insipidus is a frequent hypernatremic condition, commonly caused by abnormalities in the hypophysis; but rarely happens due to pineal tumor. A 21-year-old male with preoperative diabetes insipidus experienced episodes of diabetes insipidus complicated by cerebral salt wasting syndrome and tension pneumocephalus after a successful pineal tumor removal surgery. Closed observation on volume status, plasma glucose and electrolyte, along with optimal dose of desmopressin were keys of successful postoperative management in this patient in order to avoid the patient from secondary brain injury. An intensivist plays a key role, mainly in the understanding of intracranial pathophysiology and its implications to fluid and electrolyte balance.

Introduction. Cerebral salt-wasting syndrome and diabetes insipidus are serious complications of craniocerebral injury and spinal cord injuries. Each of the syndromes in some cases causes a life-threatening condition. This determines the importance of timely diagnosis and emergency intensive care measures. In the literature, there are only single descriptions of combinations of these symptoms in one patient.Clinical case report. A victim with craniocerebral injury and cervical spinal cord injury underwent, according to emergency indications, emptying and drainage of a tense subgaleal hematoma of the fronto-parieto-occipital region, spinal cord decompression, and stabilization of the spine. Postoperative follow-up and intensive care: on the 1st day the rate of diuresis was 2.5 mL/kg/h, blood glucose level – 14.18 mmol/L, and sodium level – 148–158 mmol/L. The patient was diagnosed with diabetes insipidus, and a therapy with desmopressin at a dose of 0.6 mg/day, restoration of fluid volume with hypotonic solutions, and correction of hyperglycemia was started. On the 4th day blood sodium level was 133 mmol/L, and blood glucose level – 8.67 mmol/L. On the 5th day, hyponatremia of 126–115 mmol/L was noted with a diuresis rate of 4 mL/kg/h and glicemya level of 7.86 mmol/L. The development of cerebral salt-wasting syndrome was diagnosed, and the infusion of hydrocortisone 400 mg/day and of 10% NaCl solution was started. On the 6th day glucose level returned to normal. On the 9th day of follow-up, an increase in the volume of diuresis was again observed, and desmopressin therapy was continued. Stable normalization of water-electrolyte balance, urine output, and glucose levels were observed on the 16th day of follow-up.Conclusion. Monitoring of fluid balance and electrolyte composition of blood serum, and adequate replacement therapy were the conditions for successful treatment of a rare combination of diabetes insipidus and cerebral salt-wasting syndrome in patients with concomitant craniocerebral and spinal cord injuries.
