When the Going Gets Tough: Pediatric Constipation and Encopresis

Neuropeptides' Hypothalamic Regulation of Sleep Control in Children Affected by Functional Non-Retentive Fecal Incontinence

Functional non-retentive fecal incontinence (FNRFI) is a common problem in pediatric age. FNRFI is defined as unintended loss of stool in a 4-year-old or older child after organic causes have been excluded. FNRFI tends to affects up to 3% of children older than 4 years, with males being affected more frequently than females. Clinically, children affected by FNRFI have normal intestinal movements and stool consistency. Literature data show that children with fecal incontinence have increased levels of separation anxiety, specific phobias, general anxiety, attention-deficit/hyperactivity disorder (ADHD), and oppositional defiant disorder. In terms of possible relationship between incontinence and sleep, disorders of sleep organization have been observed in the pathogenesis of enuresis so generating the hypothesis that the orexinergic system may have a crucial role not only for the sleep organization per se but also for the sphincterial control in general. This study aimed to focus on specific neurophysiological aspects to investigate on the possible relationship between sleep organizational abnormalities and FNRFI. Specifically, we aimed to measure orexin serum levels in children with FNRFI and assess their polysomnographic sleep macrostructure patterns. Two study groups were considered: FNFRI (n = 45) and typically developed (TD) (n = 45) group. In both groups, sleep patterns and respiratory events were assessed by polysomnographic recordings (PSG) during a period of two nights at least, and plasma levels of Orexin-A were measured in each participant. The findings of this initial investigation seem to support a major role of Orexin-A in sleep organization alterations in children with FNFRI. Also, our data suggest that sleep habits evaluation should be considered as screening and complementary tool for the diagnosis of fecal incontinence in children.

The Focal Play Therapy: A Clinical Approach to Promote Child Health and Family Well-being

Eating and evacuation disorders can cause serious health problems for children. Early recognition and early treatment require a multifactor intervention based on a collaborative relationship between pediatricians, psychotherapists and other health professionals. In this context the Focal Play Therapy (FPT) with children and parents is a psychodynamic model of intervention that improves parental ability to cope with child's difficulties. Parental engagement in child interventions allows to understand child's symptoms within family dynamics and to build an alliance with parents that represents a crucial variable of an effective psychological support for children and families. In the present study data were collected from 17 parental couples and their preschool children at two time points (1st and 6th FPT sessions) marking the first phase of this intervention. This phase was aimed to the assessment of child's symptoms within family relationships and to the promotion of the alliance with parents. Families were in treatment at the Psychological Consultation Center for Children and Parents located at the Department of Psychology of the University of Bologna (Italy). This Center provides health assessment and intervention services to children and their families. We investigated the alliance from both parents and therapist points of view along with other parental and child outcome variables implied in clinical works with children and families. Alliance scores were obtained through the Working Alliance Inventory and the System for Observing Family Therapy Alliances, two measures used in individual and family settings, respectively. Parenting stress and parent-child interactions were investigated using the Parenting Stress Index and the Emotional Availability Scales. Furthermore, paired t-tests were run to detect changes on parental and child variables. Findings advise that special attention should be paid to the building of an early alliance with parents. In this regard the FPT is specifically designed to promote the parent-therapist alliance in the context of child health and family well-being.

Constipation in Children: A Practical Review

Pediatricians and other child care providers manage a large number of children with constipation, a recurrent medical problem that is frustrating to patients, their care givers, and the health care providers themselves. Most often the constipation in children is functional in nature, and only a very small percentage of patients have an organic cause for it. In this review, we discuss the epidemiology, causes, evaluation, and management of children with functional constipation. [Pediatr Ann. 2016;45(5):e189-e196.].

Comparison of Polyethylene Glycol-Electrolyte Solution vs Polyethylene Glycol-3350 for the Treatment of Fecal Impaction in Pediatric Patients

OBJECTIVES

The objective of this study was to evaluate the safety and efficacy of polyethylene glycol-electrolyte solution vs polyethylene glycol-3350 for the treatment of fecal impaction in pediatric patients.

METHODS

A retrospective, observational, institutional review board-approved study was conducted over a 1-year time period. Patients were included in the study if they were admitted to the hospital with a diagnosis of fecal impaction or constipation and were treated with either polyethylene glycol-electrolyte solution (PEG-ES) or polyethylene glycol-3350 (PEG-3350). Patients were excluded if they were discharged prior to resolution of treatment and/or did not receive PEG-ES or PEG-3350.

RESULTS

Fifty-one patients (ranging in age from 1 month to 15 years) were evaluated: 23 patients received PEG-ES and 28 patients received PEG-3350. Sex, race, age, and weight were not statistically different between the 2 groups. Resolution of fecal impaction was not significantly different between PEG-ES vs PEG-3350 (87% and 86%, respectively; p = 0.87). There was only 1 reported side effect with PEG-3350, vs 11 reported side effects with PEG-ES (p < 0.01).

CONCLUSIONS

Theses results suggest that PEG-3350 is as effective as PEG-ES for the treatment of fecal impaction in pediatric patients and is associated with fewer side effects.

Factors relating to hospitalisation and economic burden of paediatric constipation in the state of Victoria, Australia, 2002-2009

AIM

Constipation is common, with severe symptoms requiring hospitalisation. Constipation can be a primary (present at admission and requires treatment or investigation) or principal (first listed) diagnosis for hospitalisation. In the USA, constipation is the second most common ambulatory care digestive diagnosis with total costs >US$1.7 billion/year. Incidence of hospitalisation for constipation in children peaks at toilet-training age. This study determined the burden of paediatric constipation to hospital care in Victoria, Australia.

METHOD

The Victorian Admitted Episodes Dataset was analysed retrospectively, examining hospital admissions with a primary diagnosis of constipation in the 7-year period 2002/2003 to 2008/2009.

RESULTS

For children, constipation was recorded as a primary diagnosis in 8688 admissions (3.6/1000 of population). In-hospital prevalence was ∼1.0%. Mean length of stay was 4.4 days (median 1.0, range 0-993, standard deviation 16.7). There were 1121 readmissions in 668 children. Average treatment cost was A$4235/admission (median A$1461, range A$0-$278 816), with annual costs of ∼A$5 505 500. Children in the highest socio-economic area had ∼50% fewer admissions (P < 0.0001). Predictors of readmission included age 10-18, male gender, rural residence, severe socio-economic disadvantage, public hospital, planned admission, longer length of stay and association with other medical conditions.

CONCLUSIONS

This study identified that constipation in children is a significant cost burden in Victoria (costing public hospitals ∼A$5.5 million/year). Hospitalisation in Victoria is 10-fold higher than in the USA with 10% readmissions within a month. We conclude that strategies aimed at reducing hospitalisation for constipation could result in significant savings for the paediatric public health system in Victoria, Australia.

Managing encopresis in the elementary school setting: the school nurse's role

Encopresis is a medical condition that is associated with incontinence in children. It leads to frustration and anxiety in both parents and children due to the presenting symptoms and the inability to control elimination patterns. There is overwhelming concern among families that a child with encopresis will be ostracized from peers and will suffer long-term psychological effects. It is therefore important to define encopresis to include the etiology, prevalence, and treatment measures in order to ensure a positive outcome. In addition, as a child enters elementary school, the school nurse plays a vital role in assisting the child to reach educational goals and managing health concerns. This article will guide the reader through the origin and diagnosis of encopresis as well as the principles of management. It will also delineate the school nurse role in managing encopresis in the school setting.

Impact of a nurse-led clinic for chronic constipation in children

The impact of a nurse-led constipation clinic was assessed by evaluating the first 50 patients, aged 1.5 to 10 years, using a questionnaire before initial clinic visit and at the third clinic visit, three to four months later. Patients had been constipated for at least six months. The nurses explained the physiology of constipation, the rationale for laxative treatment and the need to comply with treatment. Good toileting behaviour was encouraged. This resulted in an increase in defaecation frequency and stool softness, whereas soiling and pain on defaecation decreased. There was no significant change in the amount of laxatives taken, although it was suspected that compliance improved. Parental understanding of constipation and its management increased. Overall, the control of constipation in children improved markedly through attendance at a nurse-led clinic.

Are abdominal x-rays a reliable way to assess for constipation?

PURPOSE

Currently to our knowledge no validated reliable tools are available to evaluate constipation in children. Abdominal x-rays are often done in clinical practice to evaluate patients with lower urinary tract symptoms. Although 3 previously published rating tools exist to score constipation based on x-ray, there is little information on their merits. We assessed these 3 tools for reliability among multiple practitioners.

MATERIALS AND METHODS

We retrospectively analyzed abdominal x-rays in a cohort of 80 patients between ages 4 and 12 years. X-rays were independently assessed by each of us using the previously published Barr, Leech and Blethyn scoring tools. Scores were analyzed for reliability using standard statistical methods.

RESULTS

The range of weighted κ score, indicating reliability, were 0.0491 to 0.4809 for the Barr, 0.1195 to 0.2730 for the Leech and 0.0454 to 0.4514 for the Blethyn method. Guidelines for κ scores are greater than 0.75-excellent, 0.4 to 0.75-good and 0 to 0.4-marginal reproducibility. ICC, another reliability measure, was 0.02577 for the Barr, 0.3313 for the Leech and 0.201 for the Blethyn method. ICC interpretations are greater than 0.75-excellent, 0.4 to 0.75-good and 0 to 0.4-poor. There was a trend toward good interrater reliability between more experienced urology practitioners with the Barr and Blethyn tools (0.48 and 0.45, respectively) but not between less experienced raters or with the Leech tool.

CONCLUSIONS

Currently available scoring tools to evaluate constipation by x-ray do not have good reliability among multiple examiners. Further research is needed to develop an alternate tool to increase the reliability of x-ray to assess constipation between multiple raters.

Encopresis: a guide for psychiatric nurses

Encopresis is an elimination disorder that involves symptoms of fecal incontinence in children. It affects an estimated 1.5% to 7.5% of children ages 6 to 12 and accounts for approximately 3% to 6% of psychiatric referrals. The etiology of encopresis is thought to be related to physiologic problems such as constipation; however, it is also a psychiatric diagnosis and anecdotally may have some association with psychiatric problems. Publications on this association and publications directed toward psychiatric nurses are limited. Encopresis is typically treated with nutritional and medical management along with behavioral modification. Psychiatric nurses working with patients who have encopresis in inpatient settings will have unique concerns and challenges. This article gives an overview of published literature from the past 10 years on the etiology and treatment of encopresis. Specific suggestions for inpatient psychiatric nurses based on published literature and the author's professional experience are provided.

Encopresis, soiling and constipation in children and adults with developmental disability

Children and adults with developmental disabilities are more likely to evince encopresis, soiling and constipation than the general population. This set of related behaviors can produce a great deal of stress and can be a major restriction in independent living. This paper provides a review of the current state of knowledge on the prevalence, etiology, assessment and treatment of this co-occurring set of disorders. These problems are more common in persons with developmental disabilities then the general population. Furthermore, classical and operant treatment methods appear to be the best supported interventions for most cases. Strengths and weaknesses of the current research base are discussed along with potential avenues for future research.
