Insights

Children with monosymptomatic nocturnal enuresis often have elevated nocturnal blood pressure and a reduced day-to-night blood pressure difference. This "non-dipping" phenomenon may contribute to the development of enuresis nocturna.

Area of Science:

  • Pediatric Nephrology
  • Cardiology
  • Sleep Medicine

Background:

  • Monosymptomatic nocturnal enuresis is a common childhood condition with complex etiopathogenesis.
  • Understanding contributing factors is crucial for effective management, especially for treatment-resistant cases.

Purpose of the Study:

  • To investigate the association between nocturnal enuresis and 24-hour blood pressure profiles in children.
  • To explore potential systemic factors contributing to enuresis nocturna.

Main Methods:

  • Ambulatory blood pressure monitoring over 24 hours in 45 children with monosymptomatic nocturnal enuresis and 22 healthy controls.
  • Comprehensive medical tests including blood counts, biochemistry, urinalysis, renin-aldosterone levels, and abdominal ultrasound.

Main Results:

  • Children with nocturnal enuresis exhibited significantly higher nocturnal blood pressure levels compared to controls.
  • A significantly lower day-to-night blood pressure difference (non-dipping) was observed in enuretic children.

Conclusions:

  • Nocturnal enuresis may involve systemic factors beyond the urinary system.
  • A non-dipping blood pressure profile is identified as a potential contributing factor in the pathogenesis of enuresis nocturna.
  • Systemic evaluation is recommended for enuresis cases resistant to initial therapies.

Diabetes Insipidus II: Pathophysiology

Normally, water balance is maintained through three interconnected mechanisms: the hypothalamic thirst center, the synthesis and release of antidiuretic hormone (ADH, or vasopressin), and the kidneys' responsiveness to this hormone. ADH is synthesized in the hypothalamus, released from the posterior pituitary, and acts on the distal nephron, allowing water reabsorption and concentrated urine production.Diabetes Insipidus and Its TypesIn diabetes insipidus (DI), this regulatory system is...

Diabetes Insipidus I: Introduction

Definition Diabetes insipidus is a disorder marked by the production of large amounts of dilute urine because of impaired vasopressin production, release, or kidney response. The lack of effective vasopressin action limits water reabsorption in the renal collecting ducts, which leads to excessive urinary water loss and intense thirst.Clinical PresentationIndividuals with diabetes insipidus report persistent thirst and very high urine output. In severe cases, fluid intake can reach up to 20...

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
