As part of a community screening study to assess the long-term health outcomes among residents of Walkerton, Ontario, after contamination of its municipal water supply by Escherichia coli O157:H7 and Campylobacter in 2000, we identified 100 adults who had proteinuria and polyuria but no medical history or medication use to explain their condition. Fifty-six of the 100 participants underwent bot...
Nephrogenic diabetes insipidus (NDI) is caused by an improper response of the kidney to the antidiuretic hormone arginine vasopressin (AVP), leading to a decreased ability to concentrate urine which results in polyuria and polydipsia. The clinical diagnosis of NDI relies on demonstration of subnormal ability to concentrate urine despite the presence of AVP. NDI is most commonly acquired, second...
Lithium, a drug frequently used for treatment of affective disorders, is known to cause a vasopressin resistant state, leading to polyuria and polydipsia. It has been suggested that lithium interacts with the renal V2-vasopressin receptor and makes the receptor dysfunctional. Detailed studies on the influence of lithium on the AVP receptor, however, have so far been difficult due to the lack of...
In dogs, secondary polycythemia (SP) may be associated with polyuria and polydipsia (PU/PD). The pathogenesis of this PU/PD has not yet been explained. We hypothesized that hyperviscosity and increased blood volume in SP might affect vasopressin (VP) release, resulting in PU/PD. This hypothesis was tested in 2 dogs with SP caused by renal neoplasia and PU/PD. Osmoregulation of VP release was st...
Sheehan's syndrome refers to the occurrence of hypopituitarism after delivery, usually preceded by postpartum hemorrhage. The condition still continues to be a common cause of hypopituitarism in developing countries like India. The disorder usually presents with anterior pituitary failure with preservation of posterior pituitary functions. Posterior pituitary dysfunction in the form of central ...

Multiple factors may cause nocturia, such as behavioral or environmental factors and pathologic conditions, including cardiovascular disease, diabetes mellitus, lower urinary tract obstruction, anxiety or primary sleep disorders, and sleep apnea. Nocturia caused by any combination of these and oth...
