Enuresis in children 5-15 years at Queen Sirikit National Institute of Child Health.

A cross-sectional descriptive study was conducted to compare 179 enuretic and 811 non-enuretic patients at Queen Sirikit National Institute of Child Health from July 1998 through December 1998. The objective was to study the epidemiology, risk factors, behavioral and learning problems associated with enuresis in children 5-15 years old. Chi-squared analysis was used. The prevalence of primary, secondary and total enuresis was 15.4, 2.7 and 18.1 per cent respectively in 5-15 year old children. Of these, 88.5 per cent had nocturnal enuresis, 0.6 per cent had diurnal enuresis, 10.6 per cent had diurnal and nocturnal enuresis. Risk factors which significantly correlated with enuresis were the history of bed-wetting in the parents/sibling and inconsistent toilet training. We found that enuresis was not related to sex, birth order, LBW, socioeconomic, marital and parental educational status. Fifty-eight per cent of the parents thought that the enuretic problem needed further treatment.

[Hypnotherapy in the treatment of refractory nocturnal enuresis].

BACKGROUND: Nocturnal enuresis represents a practical, social and emotional problem. The present study illustrates the advantage of using hypnosis as a therapy in chronic cases. MATERIAL: Twelve boys, median age 12 years (range 8-16), eight with primary nocturnal enuresis and four with primary nocturnal and diurnal enuresis, reported at referral a median of 0 (range 0-3) dry nights per week. All patients had a family history of enuresis and had used enuresis alarm and Desmopressin; 50% used Imipramin. Eight had been referred to psychological or psychiatric services for treatment. METHODS: All patients had undergone a somatic assessment by a paediatrician, a paediatric surgeon, or an urologist. After a preliminary assessment of motivation, they underwent hypnotherapy with a median of six sessions (range 2-8), followed by median one month with self-hypnosis exercises. RESULTS: At follow-up after three months and one year, nine out of 12 patients had respectively 6-7/7, and 7/7 dry nights per week. Three patients had nocturnal enuresis at follow-up; two of them were referred to a paediatric surgeon for their overactive urine bladder and one was referred to his local psychiatric clinic because of ongoing family conflicts. INTERPRETATION: Hypnotherapy had lasting effects for boys with chronic and complex forms of nocturnal enuresis. We suggest that hypnotherapy should be included in the therapeutic guidelines.

Enuresis: analysis of 100 cases.

One hundred children with enuresis were studied to find out various factors responsible for this condition. Enuresis was more frequent in first born, service class and bottle fed children. There was a significant role of stress factors in causation of enuresis. We found a higher frequency of behavioral symptoms among children with enuresis. There was no significant correlation between enuresis and sex, education of parents, social class, sleep patterns, age of mother at marriage and intellectual grades of the children. Worm infestations, giardiasis, amebiasis and urinary infection were seen in 70% of cases. General body weakness, cold and nervousness were the common causes of enuresis in the parents' opinion. The main reason for not seeking the treatment at an early stage in view of parents' was that they thought enuresis a normal variant.

[Rhythmic slow wave observed on nocturnal sleep encephalogram in children with idiopathic nocturnal enuresis].

Whole-night sleep polygraph by removing the first-night effect was recorded for 15 cases of idiopathic nocturnal enuresis and 10 cases of normal control, thereby, review was made on the relation between sleep and etiology of nocturnal enuresis as well as the appearing characteristics of rhythmic slow wave. (hereinafter referred to R.S.W.). Thus the following results were obtained. Both groups of nocturnal enuresis and normal control showed no significant difference under the same experimental conditions for the rate of encephalogramic sleep stage. Nocturnal enuresis was observed in nearly the same number of cases at any stage of sleep except Stage 1 (hereinafter referred to as S), and there were many cases in the second and third sleep cycles. At the time of occurrence of nocturnal enuresis, 6-7 Hz R.S.W. continued as long as 15-40 seconds in NREM-sleep. Also, 3-5 Hz R.S.W. was observed in REM sleep. R.S.W. was observed even in normal cases, while its incidence was high in the cases of nocturnal enuresis, and the decrease was observed with advancement of age, however, the decrease was delayed in the cases of nocturnal enuresis. R.S.W. was provoked reactively against the stimuli such as the change in the electro-encephalogramic sleep stage and body movements. On the other hand, there was an inhibitory tendency of the changes in heart rate and respiration during the appearance of R.S.W. By the above result and the resemblance between R.S.W. and DR theta, R.S.W.(ABSTRACT TRUNCATED AT 250 WORDS)

[Urinary bladder dysfunction and vesicoureteral reflux in patients with enuresis].

We present preliminary results of prospective study on 38 children (aged 4-15 y.) with enuresis. The aim of the study was to document the association between bladder disfunction and urinary tract abnormalities. Enuresis was more common in girls (71%). Twenty one children (44.7%) suffered from secondary, and 17 (55.3%) from primary enuresis. High incidence of enuresis (31.6%) or voiding dysfunction, renal lithiasis, constipation of other kidney disease (42%) were disclosed among family members of children with enuresis. Urodynamic studies revealed bladder dysfunction in 84.0% of children with enuresis mostly in the form of dyssingeric (45.5%) or unstable/hyperactive bladder (45.5%). In 9% of patients bladder dysfunction as in the form of inadequate bladder with small and poor detrusor contractions often associated with large residue. Ultrasonography revealed dilatation of pyelocaliceal system in 13.2%, and vesicoureteral reflux was confirmed in 10.5% of patients. We stress out high incidence of bladder dysfunction among children with enuresis as well as among their family members.

[An update on clinical and therapeutic aspects of nocturnal enuresis].

Justification of early treatment of nocturnal enuresis is founded in the negative psychological impact on the child. In fact nocturnal enuresis delays early autonomy and socialisation by decreasing in self-esteem and self-confidence. Nocturnal enuresis classification is the preliminary step to correct therapy. Enuresis must be classified as primary (never acquired nocturnal control) or secondary (at least 6 months of dry nights). A child is also classified as having monosymptomatic enuresis if she/he experienced only night wetting and symptomatic enuresis if she/he experienced night wetting associated with diurnal voiding symptoms (urinated > or = 7 times a day, urgency, damp pants, squatting, holding the perineum, sitting on one heel). Monosymptomatic patients must be treated with desmopressin nasal spray at the daily dose of 20 micrograms at bed time. If the reduction of at least the 50% of the basal number of the wet nights is not achieved, the dosage must be increased until 40 micrograms. For patients affected by rhinitis or asthma, desmopressin is now available in tablets. In symptomatic patients desmopressin therapy must be associated to oxybutinin (5 mg x 2). Therapy interruption must be gradual with desmopressin reduction of 10 micrograms every 30 days. In symptomatic patients oxybutinin must be introduced only at bed time. The efficacy of the drugs depends on the therapy length. The highest percentage of success is obtained if the treatment is protracted for at least six months. Antidepressants are also used for nocturnal enuresis especially imipramine. The dosage varies between 0.5-1.5 mg/ kg/daily. As plasmatic levels are achieved only in 30% of treated patients, a 3-5 fold increase in suggested. Nevertheless these levels result in near toxic threshold concentration. Sporadic treatment purposes include amytriptiline, diclofenac sodicum, viloxsazine and methilphenidate if giggle incontinence is present. Non responders may be treated with alarm. If after 16 weeks of treatment no success is obtained alarm use must be interrupted.

[Enuresis and voiding disorders in childhood].

Nocturnal enuresis is a common problem seen by the primary care physician. It is mandatory to distinguish between children having monosymptomatic nocturnal enuresis with normal daytime voiding habits and patients having polysymptomatic bed wetting (associated with urgency, frequency, or other signs of unstable bladder). Investigations and treatment of polysymptomatic enuresis are different than treatment of monosymptomatic nocturnal enuresis. A thorough and thoughtful history of voiding pattern is important to separate urge syndrome from organic causes of enuresis. Management of patients who have urge syndrome include general advices like regular voiding routine, physiotherapy, anticholinergic medication and prevention or treatment of urinary tract infections. If the nocturnal enuresis persists after the control of the voiding dysfunctions, treatment of nocturnal enuresis must be undertaken.

Nocturnal enuresis: correction of renal function by desmopressin and diclofenac.

Sixty-two children with nocturnal enuresis (43 boys, 19 girls aged 6-15 years) were treated with either desmopressin (Adiuretin-SD) (n = 32) or sodium diclofenac (n = 30). Desmopressin was effective in 85% of children and diclofenac in 33%. In children with primary nocturnal enuresis, the glomerular filtration rate was normal, whereas diuresis and solute excretion during the night were increased. Compared with healthy children, the nightly excretion of sodium was elevated by 43.7% and magnesium by 58.4%. A high correlation was found between the free water reabsorption and solute clearance (P < 0.001) in children with nocturnal enuresis. Changes in kidney function in nocturnal enuresis appear to be due to a decrease in the water and ion reabsorption in the thick ascending limb of Henle's loop because of a changed regulation of ion transport in this part of the nephron. Administration of desmopressin or a decrease in prostaglandin production after diclofenac administration restores the ion and water transport in the kidney, which results in the disappearance of nocturnal enuresis. The results indicate a role of changes in regulation of ion transport in renal tubules in the pathogenesis of one of the forms of primary nocturnal enuresis.

Association between primary nocturnal enuresis and habitual snoring in children.

OBJECTIVES: Nocturnal enuresis has been associated with obstructive sleep-disordered breathing mostly in hospital-referred adults and children. To investigate whether primary nocturnal enuresis is significantly associated with habitual snoring in the general pediatric population irrespective of subjects' age and sex, we studied children attending six randomly selected schools in a city in central Greece. METHODS: A questionnaire regarding the symptoms of sleep-disordered breathing and the presence of nocturnal enuresis (bedwetting for at least one night per week) was answered by the children's parents. RESULTS: A total of 1821 children (age 5 to 14 years; 896 girls) were included in the study. Of these, 135 (7.4%) were snoring more frequently than three nights per week (habitual snorers). The habitual snorers had a history of primary nocturnal enuresis more often than did nonhabitual snorers (7.4% versus 2%; odds ratio 4.00, 95% confidence interval 1.93 to 8.32). The association of primary nocturnal enuresis with habitual snoring remained significant after adjustment for age and sex (odds ratio 3.54, 95% confidence interval 1.68 to 7.44). CONCLUSIONS: In a community sample of children, those with habitual snoring more often had primary nocturnal enuresis than did those without snoring.

Urinary calcium excretion in healthy children and children with primary monosymptomatic nocturnal enuresis.

PURPOSE: We investigated the role of urinary Ca excretion in monosymptomatic nocturnal enuresis, and defined normality and intra-individual variability in Ca excretion in healthy children. MATERIALS AND METHODS: We included 46 Danish children with desmopressin resistant nocturnal enuresis and 96 healthy controls. We performed fractional urine collections at home during 2 days in controls or during hospitalization in children with enuresis. Urine volume, osmolality, and Ca and creatinine measurements were performed and Ca-to-creatinine ratios were calculated and compared between groups. Based on nocturnal urine output children with enuresis were characterized as having polyuria (nocturnal urine volume greater than 130% of expected bladder capacity) or not having polyuria. RESULTS: We did not find any differences in controls compared with children with enuresis who did not and did have nocturnal polyuria in daytime Ca excretion (mean +/- SE 0.121 +/- 0.012, 0.078 +/- 0.014 and 0.095 +/- 0.020 mg/mg creatinine), nighttime Ca excretion (0.115 +/- 0.011, 0.092 +/- 0.019 and 0.139 +/- 0.029 mg/mg creatinine) or 24-hour Ca excretion (0.118 +/- 0.011, 0.083 +/- 0.014 and 0.106 +/- 0.020 mg/mg creatinine, respectively). Urinary Ca excretion was not influenced by patient age, sex or body weight and, furthermore, we did not find evidence of diurnal variation. However, we observed considerable intra-individual variability in diurnal, nocturnal and total 24-hour urinary Ca-to-creatinine ratios. CONCLUSIONS: These observations contradict several previous reports and speculations on a role of Ca in the pathogenesis of nocturnal enuresis.

Enuresis: principles of management and result of treatment.

We studied 115 consecutive cases of primary enuresis. Excretory urography, urodynamic testing and endoscopy are needed only in children with enuresis and concomitant urinary infection. A detailed urologic history was the most important factor in deciding upon a treatment program. Children with diurnal and nocturnal enuresis or nocturnal enuresis and daytime urgency and frequency of urination are started on anticholinergic medication. Girls with enuresis and urinary infection also are started on anticholinergic medication. Significant improvement occurs in up to 90% of the patients. Children with only nocturnal enuresis and no other symptoms are started on imipramine with a 70% improvement rate.

Childhood enuresis.

Enuresis is not a disease, but rather a benign clinical disorder that is very common in young children. In considering the many facets of enuresis, physicians caring for children with this disorder should always remember the dictum "Primum non nocere". Most children with enuresis will be found to have primary enuresis, that is, no organic disease or psychopathology will be found. Physicians should proceed cautiously and should avoid costly, harmful and unnecessary workups. Treatment of few disorders is more dependent on the art and skill of clinical medicine than that of childhood enuresis. All of the physician's talents and compassionate nature enter into the proper evaluation of and therapy for this disorder. Physicians must keep in mind the high spontaneous cure rate. This factor alone should encourage them to be extremely optimistic about the outcome of enuresis in their pateints.

Neuromotor development in nocturnal enuresis.

In children with nocturnal enuresis, a higher rate of minor neurological dysfunction has been found. The aim of this study was to assess timed performance (a measure of motor performance speed) and associated movements using a standardized and reliable instrument. The motor function of 37 children with nocturnal enuresis (27 males, 10 females; mean age 10y 7mo [SD 1y 10mo]; age range 8y-14y 8mo) and 40 comparison children without enuresis (17 males, 23 females; mean age 10y 7mo [SD 1y 6mo]; age range 8y-14y 8mo) was assessed using the Zurich Neuromotor Assessment. Children with nocturnal enuresis showed a slower motor performance than comparison children, particularly for repetitive hand and finger movements. This study provides evidence for a maturational deficit in motor performance in children with nocturnal enuresis. In addition to a maturational deficit of the brainstem, it is proposed that there is a possible maturational deficit of the motor cortex circuitry and related cortical areas in children with nocturnal enuresis.

Desmopressin for nocturnal enuresis: urinary osmolality and response.

OBJECTIVE: To measure the effect of intranasal desmopressin (l-deamino 8-D-arginine vasopressin, DDAVP) on urine osmolality in a group of patients with persistent primary enuresis, and to determine whether changes in osmolality can the predict response to treatment. PATIENTS AND METHODS: Thirty-seven patients with persistent primary nocturnal enuresis were entered into a double-blind placebo-controlled crossover trial of 20 micrograms intranasal DDAVP spray. Morning urinary osmolality was measured on two occasions during each phase of treatment and the clinical response recorded in a diary. RESULTS: Thirty-one patients (22 males and nine females) were evaluable at the end of the trial period. A good clinical response, defined as enuresis on two nights or fewer each week, occurred in 12 of 31 (39%) patients, but complete continence was attained in only two. The response was better in older patients and in those with less frequent enuresis. The mean and peak urinary osmolality of the morning urine samples were higher while on treatment with DDAVP compared with placebo, but this difference was not statistically significant and the response did not predict a good clinical outcome in improving the enuresis. CONCLUSIONS: Treatment with DDAVP can produce a socially acceptable level of dryness in some patients with refractory nocturnal enuresis. However, the early morning urinary osmolality, as a reflection of changes in nocturnal osmolality, was not useful in distinguishing this group or in selecting those who will respond to treatment.

Urinary excretion of glycosaminoglycans in patients with isolated nocturnal enuresis or combined with diurnal incontinence.

OBJECTIVE: To determine variations in the amount of glycosaminoglycans (GAGs) excreted by patients with nocturnal enuresis and/or diurnal incontinence. PATIENTS, SUBJECTS AND METHODS: The study included 27 patients (aged 5-15 years) with nocturnal enuresis and/or diurnal incontinence, and 27 healthy age-matched children. Their urinary GAG excretion was assessed over 24 h using the sodium tetraborate-carbazole method. RESULTS: Patients with nocturnal enuresis and/or diurnal incontinence had higher mean values of urinary GAG excretion than age-matched controls. There were significant differences in GAG excretion between those with nocturnal enuresis and diurnal incontinence and those with nocturnal enuresis alone. CONCLUSIONS: GAG excretion in patients with nocturnal enuresis and/or diurnal incontinence was significantly higher than in normal children, suggesting that measuring urinary GAGs may be useful in evaluating physiopathological conditions of the bladder wall, and hence in monitoring potential damage in the bladder mucosa.

Incidence of nocturnal enuresis and nocturia in children with tuberculosis.

Nocturnal enuresis is a common problem and occurs in 15 to 20 percent of 5-year-old children. The etiology of nocturnal enuresis remains unknown and is probably multifactorial. In this study 52 children aged between 6-17 years with tuberculosis were questioned for nocturia and nocturnal enuresis, retrospectively. Nocturnal, enuresis was found in 12 (23%) and nocturia in 22 (42%) of the children, respectively. After specific treatment with antituberculosis drugs nocturnal enuresis and nocturia were improved in 5 and 21 children, respectively. However, it could not be explained why these disorders were much higher in children with tuberculosis than healthy children. The findings suggest that nocturnal enuresis and nocturia may be in a high frequency in children with tuberculosis; however, the authors think that prospective and more extensive studies should be performed to clarify these preliminary findings.

Enuresis in cross-cultural perspective: a comparison of training for elimination control in three Israeli ethnic groups.

Enuresis was investigated in the context of different styles of training for bladder control among three Israeli ethnic groups (Jews of Moroccan, Kurdish or Eastern European descent). Semistructured interviews were conducted in ethnically homogeneous agricultural villages with 46 mothers of 248 children between the ages of 3 and 18 years. In contrast to previous British and American studies, no sex differences were found, but there were higher rates of primary enuresis and lower rates of secondary (regressive) enuresis. Enuresis was correlated among siblings in the Kurdish group only and with disorderly sleeping arrangements in the Moroccan group. The Moroccan and Kurdish groups had higher rates of enuresis than the Ashkenazi group. The higher rates appear to be related to differences in the age of onset of training and a lack of age-appropriate changes in the parent-child interaction, which led to chronic enuresis and the inability to seek effective assistance. These results are discussed in terms of a proposed typology for training: an early symbiotic style, a strict toddler style, and a communicative partnership.

Possible role of prostaglandins in pathogenesis of nocturnal enuresis in children.

OBJECTIVE: To compare excretion of ions and prostaglandins by the kidney in children with noctural enuresis. MATERIAL AND METHODS: Thirty-two children with primary nocturnal enuresis and 23 normal children were examined. Osmolality and sodium and potassium concentrations were measured in their urine and blood serum. Prostaglandins E2, E1, and F2alpha were determined using kits for immunoenzyme analysis. Luminal and contraluminal prostaglandin secretions were studied in frog urinary bladder. RESULTS: Children with nocturnal enuresis have increased nocturnal diuresis and renal sodium excretion, but no increase was found in excretion of prostaglandins E2, E1, and F2alpha. Administration of sodium diclofenac before bed-time eliminated episodes of nocturnal enuresis in 37% of children; intranasal administration of Adiuretin SD had a positive effect in 69% of enuretics. In children with nocturnal enuresis there is a correlation between renal excretion of PGE2 and sodium ions; this correlation is absent in the control group children, and disappears in enuretics treated with desmopressin. To evaluate the representativeness of the data on prostaglandin secretions to urine as compared with their release to extracellular fluid, experiments on frog urinary bladder were performed: a correlation was found between prostaglandin secretion to the urinary bladder lumen and to the extracellular fluid. CONCLUSIONS: The results of the study suggest that changes in renal function are due not to a higher secretion of prostaglandins in nocturnal enuresis but to the relative dominance of their effect as compared with other physiologically active substances that simultaneously act on renal tubular cells.
