Acute fatty liver of pregnancy (AFLP) is a rare liver disease unique to pregnancy that can lead to acute liver failure. The prognosis, initially often fatal for both mother and child, has been improved by prompt delivery. The diagnosis should be highly suspected if the mother presents epigastric pain, nausea and/or vomiting, or polyuria-polydipsia in the third trimester of pregnancy. AFLP has been found associated with a genetic deficiency of fatty acid beta-oxidation, which may cause sudden death in infancy...

Diabetes insipidus is a syndrome that associates both hypotonic polyuria and polydipsia, due to insufficient or ineffective arginine vasopressin (AVP) synthesis, or to AVP resistance. The diagnosis between central/renal origin, or an abnormal thirst regulation (primary polydipsia) is required to organize an adapted management. Because water deprivation tests are not reliable, it's often based on medical history, response to treatment and MRI. Copeptin is an AVP precursor which could be very helpful for the diagnosis...

RATIONALE: A hyperosmolar hyperglycemic state (HHS) is a rare presentation of a hyperglycemic crisis in children with diabetes mellitus. As this condition can be fatal and has high morbidity, early recognition and proper management are necessary for a better outcome. Here, we report a rare case of HHS as the first presentation of type 1 diabetes mellitus (T1DM) in a 7-year-old girl. PATIENT CONCERNS: The patient was admitted due to polyuria and weight loss in the past few days...

INTRODUCTION: Advice (BBA) into the standards of patients' care in both monosymptomatic and non-monosymptomatic nocturnal enuresis. Although the idea of this recommendation was clear and reflects clinical experience, duration and efficacy have not been definitely established. Recent data have demonstrated the lack of efficacy of BBA and a fierce discussion has ensued. The present study was aimed to assess the efficacy of BBA in a group of previously untreated children with primary monosymptomatic nocturnal enuresis (MNE)...

Central diabetes insipidus (DI) is a rare clinical entity characterized by low circulating levels of antidiuretic hormone (ADH) presenting with polyuria and volume depletion. Pituitary surgery is the most common cause of central DI in adults. Pituitary and hypothalamic disease, particularly invasive neoplasms, rarely cause DI, being idiopathic cases responsible for the majority of non-surgical cases. HIV patients, especially those with poor virulogical control, are prone to the development of CNS neoplasms, particularly lymphomas...

Apelin, a (neuro)vasoactive peptide, plays a prominent role in controlling body fluid homeostasis and cardiovascular functions. In animal models, experimental data demonstrate that intracerebroventricular injection of apelin into lactating rats inhibits the phasic electrical activity of arginine vasopressin (AVP) neurons, reduces plasma AVP levels, and increases aqueous diuresis. In the kidney, apelin increases diuresis by increasing the renal microcirculation and by counteracting the antidiuretic effect of AVP at the tubular level...

Lithium is the mainstay treatment for patients with bipolar disorder, but generally causes nephrogenic diabetes insipidus (NDI), a disorder in which the renal urine concentrating ability has become vasopressin-insensitive. Li-NDI is caused by lithium uptake by collecting duct principal cells and downregulation of AQP2 water channels, which are essential for water uptake from pro-urine. Recently, we found that the prophylactic administration of acetazolamide to mice effectively attenuated Li-NDI. To evaluate whether acetazolamide might benefit lithium-treated patients, we administered acetazolamide to mice with established Li-NDI and six patients with a lithium-induced urinary concentrating defect...

PURPOSE OF REVIEW: Antenatal Bartter syndrome (aBS) is a heterogenous disease resulting from defective ion transport in the thick ascending limb of the loop of Henle. Novel insights into the pathophysiology, as well as the recent identification of a novel genetic cause of aBS, merit an update on this topic. RECENT FINDINGS: In aBS, severe salt losing is further aggravated by defective salt sensing in the macula densa, where a reduced tubular salt concentration is perceived and glomerular filtration is increased instead of decreased...

Pituitary abscess is an uncommon pituitary lesion. Its clinical diagnosis can be difficult to distinguish from other pituitary lesions. This pathology is characterised by vague symptoms of headaches, generalised tiredness and hypopituitarism manifestations. A history of recent meningitis, paranasal sinusitis or head surgery can be a suggestive of the source of infection.A 20-year-old man was admitted to neurosurgery department with complain of headache, fatigue, polyuria, polydipsia, blurred vision and sexual dysfunction...

A 23-year-old male trauma patient with a cervical spine fracture underwent an anterior and posterior discectomy and spinal fusion surgery. The patient presented to the operating room with a stabilizing halo fixation device in place, and a fiberoptic intubation was performed with dexmedetomidine for sedation. During the surgical procedure, general anesthesia was maintained with a propofol and remifentanil infusion as the patient was monitored using somatosensory and motor evoked potentials. The patient's urine output increased gradually during the nine-hour surgical procedure from 150 mL/hour to over 700 mL/hour in the eighth hour of the procedure, where it remained until the end of the procedure...

BACKGROUND Sjögren's syndrome is an autoimmune disorder caused by the infiltration of monocytes in epithelial glandular and extra-glandular tissues. Hallmark presentations include mouth and eye dryness. Although renal involvement is uncommon in primary Sjögren's syndrome (pSS), patients may experience renal tubular acidosis type I (RTA I), tubulointerstitial nephritis, diabetes insipidus (DI), nephrolithiasis, and Fanconi syndrome. However, it is atypical to see more than 1 of these manifestations in a single patient...

Diabetic cardiomyopathy is a major contributor to the increasing burden of heart failure globally. Effective therapies remain elusive, in part due to the incomplete understanding of the mechanisms underlying diabetes-induced myocardial injury. The objective of this study was to assess the direct impact of insulin replacement on left ventricle structure and function in a rat model of diabetes. Male Sprague-Dawley rats were administered streptozotocin (55 mg/kg i.v.) or citrate vehicle and were followed for 8 weeks...

Experimental or spontaneous genomic mutations of the renin-angiotensin system or its pharmacological inhibition in early life leads to renal abnormalities, including poorly developed renal medulla, papillary atrophy, hydronephrosis, inability to concentrate the urine, polyuria, polydipsia, renal failure, and anemia. At the core of such complex phenotype is the presence of unique vascular abnormalities: the renal arterioles do not branch or elongate properly and they have disorganized, concentric hypertrophy...

The incidence and prevalence of type 1 diabetes (T1D) are increasing among white, black, Hispanic, and Asian individuals in the United States. Children often present with acute symptoms, including severe polyuria, polydipsia, weight loss, and ketonemia; adults may develop more gradual symptoms that initially appear similar to those of type 2 diabetes (T2D). Latent autoimmune diabetes of adults and maturity-onset diabetes of the young are conditions that may be confused with T1D, although they are actually more closely related to T2D...

Carcinoid tumors are neuroendocrine tumors that mainly arise in the gastrointestinal tract, lungs, and bronchi. Bronchopulmonary carcinoids have been associated with Cushing syndrome, which results from ectopic adrenocorticotrophic hormone (ACTH) secretion. We report the case of a 65-year-old man, a colonel in the US Air Force, with metastatic bronchopulmonary carcinoid tumors treated on a clinical trial who was hospitalized for complaints of increasing thirst, polydipsia, polyuria, weakness, and visual changes...

The transcription factor hepatocyte nuclear factor-1β (HNF-1β) is essential for normal kidney development and function. Inactivation of HNF-1β in mouse kidney tubules leads to early-onset cyst formation and postnatal lethality. Here, we used Pkhd1/Cre mice to delete HNF-1β specifically in renal collecting ducts (CDs). CD-specific HNF-1β mutant mice survived long term and developed slowly progressive cystic kidney disease, renal fibrosis, and hydronephrosis. Compared with wild-type littermates, HNF-1β mutant mice exhibited polyuria and polydipsia...
