Summary
Children with primary nocturnal enuresis show impaired afferent pathway function. Pudendal and tibial somatosensory evoked potentials were slower, particularly in complicated cases, indicating potential nerve dysfunction.
Area of Science:
- Neuroscience
- Pediatrics
- Urology
Background:
- Primary nocturnal enuresis (PNE) affects many children.
- The underlying neurophysiological mechanisms are not fully understood.
- Investigating afferent pathway function is crucial for PNE management.
Purpose of the Study:
- To evaluate afferent pathway dysfunction in children with PNE.
- To measure pudendal somatosensory evoked potential (PSEP) and tibial somatosensory evoked potential (TSEP).
- To compare neurophysiological findings between complicated PNE (CPE) and monosymptomatic PNE (MPE) groups.
Main Methods:
- Enrolled 36 boys and 18 girls aged 5-16 years with PNE.
- Included 24 CPE and 30 MPE subjects.
- Excluded participants with significant urological/neurological abnormalities, except spina bifida occulta.
Main Results:
- Positive PSEP recordings were observed in all MPE and 20 CPE children (P < 0.05).
- TSEP was successfully recorded in both groups.
- Both PSEP and TSEP conduction velocities were slower than normal, especially in the CPE group (P < 0.001).
Conclusions:
- Afferent pathway dysfunction is implicated in primary nocturnal enuresis.
- Impaired nerve conduction velocities suggest underlying neurophysiological factors.
- Clinicians and parents should consider these findings in managing PNE.

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...

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...
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.

Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
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 comprises four progressive stages that seamlessly merge:

Disorders of the Urinary System
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
