Effectiveness of treatments for nocturnal enuresis in a heterogeneous population

An exploration of outcome criteria in nocturnal enuresis treatmentThe way forward

This paper is a review of outcome definitions and criteria for nocturnal enuresis treatment. A search of the literature published between 1991 and 2001 highlighted 97 papers. Although the International Children's Continence Society and the World Health Organization have published outcome criteria, different, often idiosyncratic, outcome criteria and/or definitions have been adopted in published research on treatment for nocturnal enuresis in recent years. There remains a debate as to what constitutes successful treatment and how to document improvement. Lack of an agreed definition of outcome reduces confidence in comparing studies, with serious clinical and research implications. This paper reviews aspects of importance in determining outcome, including a suggestion to focus on the establishment of dry nights rather than the reduction of wet nights. A new set of criteria is suggested, consisting of a banding system referred to as a "dryness scale", which focuses on the percentage of dry nights accomplished at a point in time, thus eliminating the need to compare current levels of dryness with a baseline.

Secondary diurnal enuresis treated with hypnosis: a time-series design

A case of secondary diurnal enuresis (SDE) after a car accident was treated with hypnosis by means of the Hypnotic Trauma Narrative, an instrument created by the authors for use with children who have been exposed to traumatic events and develop either classic symptoms of posttraumatic stress disorder or manifest other psychosomatic symptoms. An ABAB time-series design with multiple replications was employed to measure the relationship of the hypnotic treatment to the dependent measure: episodes of diurnal incontinence. The findings indicated a statistically significant relationship between the degree of change from phase to phase and the treatment. Hypnosis with the Hypnotic Trauma Narrative was deemed efficacious as a method for the treatment of secondary diurnal enuresis. The patient was symptom-free at follow-up 6 months later.

Nocturnal enuresis: behavioral treatments

Nocturnal enuresis is a common problem. Physiologic and environmental factors are thought to have a role in the etiology and treatment of this condition. This article discusses the association between enuresis and behavioral or emotional problems. Common behavioral treatments are described, and evidence for their efficacy is reviewed. A brief discussion of hypnosis and acupuncture is included.

Nocturnal enuresis

Nocturnal enuresis is a benign condition, yet needs treatment to relieve the child and parents of the accompanying anxiety and the stigma attached to it. It is defined as normal nearly complete evacuation of the bladder at a wrong place and time at least twice a month after the fifth year of life. The underlying cause of enuresis is functional and various proposed pathophysiological mechanisms like maturational delay, genetics, role of sleep, antidiuretic hormone, and bladder capacity are discussed. These factors have a bearing on the management. As no treatment plan is ideal, various treatment modalities currently available including good supportive care are elaborated and a plan of management discussed.

Design and reporting modifications in industry-sponsored comparative psychopharmacology trials

This review of recently published pharmaceutical industry-sponsored comparative psychotropic drug trials aims to classify apparent design and reporting modifications that favor the sponsor's product. The modifications have been grouped into 13 discrete categories, and representative examples of each are presented. Strong circumstantial evidence suggests that marketing goals led to these adjustments. The consequences of marketing influences on comparative psychopharmacology trials are discussed in terms of conflicts of interest, the integrity of the scientific literature, and costs to consumers, as well as their impact on physician practice.

The role of pelvic traction in the management of primary monosymptomatic nocturnal enuresis

OBJECTIVE

To determine whether pelvic traction is beneficial in children with primary nocturnal enuresis.

PATIENTS AND METHODS

There can be disproportionate growth between the spinal column and neural tube in prepubertal children. The normal elongation of the vertebral column in children during sleep could stretch the filum terminale and nerve roots, representing a minor degree of tethering that affects neural function and contributes to nocturnal enuresis. Pelvic traction induces a similar or more intense stretch while a patient is fully awake (and able to control their bladder). Releasing the potential tethering in this way, combined with conditioning therapy, could be beneficial. Fifty patients (aged 7-17 years) with monosymptomatic primary nocturnal enuresis were evaluated in a prospective study. All had 10 sessions of pelvic traction applied over 4 weeks and were followed up for 3 months afterward; no other medications were given.

RESULTS

All patients had fewer wet nights, with variable degrees of success (20-80%) during and 3 months after traction.

CONCLUSION

Pelvic traction is a safe, simple, economic and effective treatment for primary monosymptomatic nocturnal enuresis.
