A reset osmostat as a cause of hyponatremia can be found in a variety of clinical settings, including pulmonary and neurologic diseases, as well as in physiologic circumstances such as pregnancy. This teaching case describes a 72-year-old white man with a long-standing history of self-medicating with desmopressin acetate (DDAVP) who presented with profound hyponatremia. On discontinuation of DDAVP treatment, he was found to have a reset osmostat. The mild hyponatremia persisted on follow-up. We theorize that the reset osmostat may have developed secondary to long-standing DDAVP use...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) has various causes including central nervous system disorders, pulmonary and endocrine diseases, paraneoplastic syndromes, and use of certain drugs. SIADH induced by chemotherapy with irinotecan-cisplatin is not a common complication. Here, we review a case of SIADH after treatment with irinotecan-cisplatin. A 45-year-old woman received adjuvant chemotherapy (paclitaxel-carboplatin) for ovarian clear cell carcinoma, but the cancer recurred within 9 months of chemotherapy...

Case report describing the finding of central pontine myelinolysis (CPM) using combined fluorine-18 ( (18)F)-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). The patient was a known alcoholic who, during admission was under treatment for hyponatremia, showed a significant decline in both motor and cognitive function. Combined (18)F-FDG PET/CT showed localized FDG uptake in the pons, consistent with the finding of CPM observed on magnetic resonance imaging (MRI). CPM is a demyelinating lesion of the pons, resulting in several neurological symptoms...

BACKGROUND: The importance of hyponatremia is underestimated despite it is a frequent alteration in a hospital environment. Usually no cause is investigated and it is treated as an isolated data. The aim was to determine the prevalence and etiology of hyponatremia in pediatric patients. METHODS: Cross-sectional study of 72 patients from 1-month to 15-years of age admitted to the emergency room, from May to September, 2015, with lower serum determination of Na < 135 mEq/L at admission...

A 76-year-old woman was diagnosed with lung tuberculosis. On the second day of anti-tuberculosis treatment, she became unconscious and developed status epilepticus accompanied by hyponatremia. The hyponatremia was caused by the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Detailed examinations revealed that the patient's status epilepticus had occurred due to hyponatremia, which was caused by lung tuberculosis-associated SIADH. Previous case reports noted that patients with tuberculosis-associated SIADH showed mild clinical manifestations...

EDITORIAL
Detlef Bockenhauer
Hyponatremia is a common complication in neonatal polycystic kidney disease and is thought to be due to water retention. Aquaretics are drugs that promote free water excretion by blocking the arginine vasopressin receptor type 2 (AVPR2) in the collecting duct and thus impair urinary concentration. AVPR2 is also a key stimulant for cyclic AMP production in the collecting duct and in this way promotes cyst proliferation and pathologic kidney growth in autosomal dominant polycystic kidney disease (ADPKD). Consequently, the aquaretic tolvaptan is now used to slow down progression of ADPKD in adult patients...

A 34-year-old woman was admitted to hospital after sustaining a head injury in a motor vehicle accident (day 1). No signs of neurological deficit, skull fracture, brain contusion, or intracranial bleeding were evident. She was discharged without symptoms on day 4. However, headache and nausea worsened on day 8, at which time serum sodium level was noted to be 121 mEq/L. Treatment with sodium chloride was initiated, but serum sodium decreased to 116 mEq/L on day 9. Body weight decreased in proportion to the decrease in serum sodium...

BACKGROUND: Cardiorenal anemia syndrome (CRAS) is an evolving global epidemic associated with increased morbimortality and cost of care. The management of patients with CRAS remains a challenging undertaking worldwide and the lack of evidence-based clinical guidelines adds to the challenge. We aimed to explore the prevalence and survival rates of heart failure patients with CRAS in Tanzania. METHODS: We screened 789 patients and consecutively recruited 463 who met the inclusion criteria...

Matthew David Kagan, Kara Schmidt, Gurtej Sangha
This paper details the case of a 26-year-old woman with depletion syndrome and the effectiveness of her treatment with indomethacin. Villous adenomas are benign neoplasms with a high incidence of becoming malignant. A small percentage of villous adenomas are known to cause depletion syndrome, also referred to as the McKittrick-Wheelock syndrome, a condition characterised by secretory diarrhoea, dehydration, hyponatremia, hypokalaemia, hypochloraemia, metabolic acidosis and acute renal failure. Prostaglandin-E2 mediates the hypersecretion mechanism observed in depletion syndrome, and can be inhibited by cyclo-oxygenase inhibitors...

Gitelman's syndrome (GS) is a rare autosomal recessive disorder caused by mutations in thiazide-sensitive NaCl cotransporter. We report a 49-year-old, normotensive lady with prolonged hypokalemia since her 20s who was diagnosed with GS at our renal clinic. During follow-up, she was found to have mild, asymptomatic, euvolemic hyponatremia with low serum uric acid, inappropriately high urine osmolality and sodium consistent with syndrome of inappropriate antidiuretic hormone-like presentation. Despite life-long urinary sodium losses, hyponatremia has rarely been reported in GS to be due to the primary disease process...

Hyponatremia is the most common electrolyte disorder observed in hospitalized patients. The most severe forms are neurological and potentially fatal emergencies; yet increased morbidity, length of hospital stay and costs associated with less severe forms are aspects of major concern. Nephrologists are frequently consulted regarding the therapeutic management and the key pathophysiological issues of hyponatremia, as this latter aspect represents a true challenge in an emergency setting. We report a case of a woman admitted to the emergency room for gait instability caused by a very severe multifactorial hyponatremia with a favourable clinical outcome...

Hyponatremia is a common water balance disorder that often poses a diagnostic or therapeutic challenge. Therefore, guidelines were developed by professional organizations, one from within the United States (2013) and one from within Europe (2014). This review discusses the diagnosis and treatment of hyponatremia, comparing the two guidelines and highlighting recent developments. Diagnostically, the initial step is to differentiate hypotonic from nonhypotonic hyponatremia. Hypotonic hyponatremia is further differentiated on the basis of urine osmolality, urine sodium level, and volume status...

BACKGROUND: Symptomatic hyponatremia is considered a rare complication of oral bowel preparation for colonoscopy. The pathophysiology underlying this phenomenon has been widely regarded as a mere sequela of excessive arginine vasopressin (AVP) release. CASE PRESENTATION: This case describes a 61-year old woman who developed acute hyponatremic encephalopathy when preparing for elective outpatient lower endoscopy. She had had negligible oral solute intake for two days and ingested four liters of clear fluid within two hours...

Ravi Garg, Barak Bar
Many systemic complications follow aneurysmal subarachnoid hemorrhage and are primarily due to sympathetic nervous system activation. These complications play an important role in the overall outcome of patients. The purpose of this review is to provide an update on the diagnosis, pathophysiology, and management of systemic complications specifically associated with aneurysmal subarachnoid hemorrhage. Special focus has been made on systemic complications that occur more frequently in patients with aneurysmal subarachnoid hemorrhage compared to other stroke subtypes and in the neurocritical care patient population...

REVIEW
Julien Guillaumin, Stephen P DiBartola
The article focuses on causes of hyponatremia, including hypovolemia, diabetes mellitus and others. Hypovolemia is a major cause of hyponatremia in veterinary medicine. Hypovolemia causes a decrease in effective circulating volume, triggering antidiuretic hormone (ADH) secretion and free water retention, and develops after gastrointestinal losses, renal losses, hemorrhagic shock, hypoadrenocorticism, and other causes of hypovolemia. The article reviews the clinical approach to diagnosing the cause of hyponatremia in critically ill patients, including recognition of the syndrome of inappropriate ADH secretion (SIADH)...
