Computerized adaptive testing to screen children for emotional and behavioral problems by preventive child healthcare.

BACKGROUND: Questionnaires to detect emotional and behavioral problems (EBP) in Preventive Child Healthcare (PCH) should be short which potentially affects validity and reliability. Simulation studies have shown that Computerized Adaptive Testing (CAT) could overcome these weaknesses. We studied the applicability (using the measures participation rate, satisfaction, and efficiency) and the validity of CAT in routine PCH practice. METHODS: We analyzed data on 461 children aged 10-11 years (response 41%), who were assessed during routine well-child examinations by PCH professionals. Before the visit, parents completed the CAT and the Child Behavior Checklist (CBCL). Satisfaction was measured by parent- and PCH professional-report. Efficiency of the CAT procedure was measured as number of items needed to assess whether a child has serious problems or not. Its validity was assessed using the CBCL as the criterion. RESULTS: Parents and PCH professionals rated the CAT on average as good. The procedure required at average 16 items to assess whether a child has serious problems or not. Agreement of scores on the CAT scales with corresponding CBCL scales was high (range of Spearman correlations 0.59-0.72). Area Under Curves (AUC) were high (range: 0.95-0.97) for the Psycat total, externalizing, and hyperactivity scales using corresponding CBCL scale scores as criterion. For the Psycat internalizing scale the AUC was somewhat lower but still high (0.86). CONCLUSIONS: CAT is a valid procedure for the identification of emotional and behavioral problems in children aged 10-11 years. It may support the efficient and accurate identification of children with overall, and potentially also specific, emotional and behavioral problems in routine PCH.

Diagnostic accuracy of referral criteria for head circumference to detect hydrocephalus in the first year of life.

BACKGROUND: Increased head circumference is often the first and main sign leading to the diagnosis of hydrocephalus. Our aim is to investigate the diagnostic accuracy of referral criteria for head circumference to detect hydrocephalus in the first year of life. METHODS: A reference group with longitudinal head circumference data (n = 1938) was obtained from the Social Medical Survey of Children Attending Child Health Clinics study. The case group comprised infants with hydrocephalus treated in a tertiary pediatric hospital who had not already been detected during pregnancy (n = 125). Head circumference data were available for 43 patients. Head circumference data were standardized according to gestational age-specific references. RESULTS: Sensitivity and specificity of a very large head circumference (>2.5 standard deviations on the growth chart) were, respectively, 72.1% (95% confidence interval [CI]: 56.3-84.7) and 97.1% (95% CI:96.2-97.8). These figures were, respectively, 74.4% (95% CI: 58.8-86.5) and 93.0% (95% CI:91.8-94.1) for a large head circumference (>2.0 standard deviation), and 76.7% (95% CI:61.4-88.2) and 96.5% (95% CI:95.6-97.3) for a very large head circumference and/or a very large (>2.5 standard deviation) progressive growth of head circumference. CONCLUSIONS: A very large head circumference and/or a very large progressive growth of head circumference shows the best diagnostic accuracy to detect hydrocephalus at an early stage. Gestational age-specific growth charts are recommended. Further improvements may be possible by taking into account parental head circumference.

At what age is hydrocephalus detected, and what is the role of head circumference measurements?

To investigate at what age hydrocephalus is detected and to assess the role of head circumference measurements in detecting hydrocephalus, we performed a retrospective chart review in children with hydrocephalus treated in a tertiary paediatric hospital in the Netherlands. The study group contained 146 patients; 38 patients (31%) were referred because of abnormalities in head circumference. Eighty-nine per cent of the patients were detected in the first year of life. After this period, no patients were referred because of an abnormal head circumference. Therefore, head circumference measurements seem to have little value for detecting hydrocephalus after the first year of life.

[Youth Healthcare guideline 'Skin disorders']. / Jeugdgezondheidszorgrichtlijn 'Huidafwijkingen'.

There is a high incidence of skin disorders; these are also frequently encountered within Youth Healthcare (YHC). Some skin disorders are caused by an underlying disease, syndrome or child abuse. Therefore, detection of these causes in an early stage is important. Skin disorders can have a huge psychosocial impact on both child and parents. This is one of the reasons why prevention, detection, diagnosis, treatment, referral, and uniform advice and guidance are of great importance. The YHC Guideline examines counselling and advice, criteria for referral to primary or secondary healthcare, and skincare in general. It also describes the disorders that should be actively detected. The Guideline also looks at specific aspects of dark skins and ethnic diversity, and the impact of skin disorders on general wellbeing. The accompanying web-based tool includes argumentation and opinions from experts on more than 75 skin disorders, including illustrations and decision trees, to aid the drawing up of a treatment plan.

[Guideline 'Incontinence urine and feces' of the Dutch Preventive Youth Health Care]. / Jeugdgezondheidszorgrichtlijn 'Zindelijkheid urine en feces'.

Continence problems can occur during childhood. This guideline is for the Dutch Youth Health Care (JGZ) and gives recommendations for the prevention, early detection and treatment of these problems. As a preventative measure advices for potty training should be started in children aged 18-24 months. If incontinence is present, it is important to take a history and carry out physical examination. In children over the age of 5 who are incontinent of urine the following are recommended: taking child out of bed, calendar with reward system, bedwetting alarm or voiding diary; children over the age of 8 can follow dry bed training. Faecal incontinence is often associated with constipation. Incontinent children with constipation are given advice about normal eating and exercise patterns. If this is not successful then laxatives are prescribed. The JGZ should refer further if there are indications of an underlying condition; if children over the age of 5 are wet during the day; if children are incontinent of faeces at night; if children are incontinent of faeces but not constipated; if children persistently wet the bed; if there is faecal incontinence despite counselling, and if medication needs to be prescribed.

Non-VACTERL-type anomalies are frequent in patients with esophageal atresia/tracheo-esophageal fistula and full or partial VACTERL association.

BACKGROUND: The VACTERL association is the nonrandom co-occurrence of Vertebral anomalies, Anal atresia, Cardiovascular malformations, Tracheo-esophageal fistula (TEF) and/or Esophageal atresia (EA), Renal anomalies, and/or Limb-anomalies. The full phenotype of patients with EA/TEF and other anomalies of the VACTERL spectrum of defects association is not well described in the literature. METHODS: Data on patients with EA/TEF seen in two pediatric surgical centers in the Netherlands between January 1988 and August 2006 were evaluated for defects of the VACTERL spectrum as well as non-VACTERL-type defects. The presence of two or more defects of the VACTERL spectrum in addition to EA/TEF was the criterion for inclusion in this study. A detailed description was made of all defects. RESULTS: Of 463 patients with EA and/or TEF, 107 (23.1%) fulfilled the inclusion criterion, of which seventeen cases had a recognized etiology and were excluded, leaving 90 cases (19.4%) for analysis. Other than the esophagus and the trachea, the vertebrae/ribs and the cardiovascular system were most commonly affected (68.9 and 65.6%, respectively). Interestingly, 70% of cases had additional non-VACTERL-type defects, with high occurrences for single umbilical artery (20%), genital defects (23.3%), and respiratory tract anomalies (13.3%). CONCLUSIONS: Many patients with EA/TEF and at least two other defects of the VACTERL spectrum also display non-VACTERL-type congenital anomalies.

Young adult patients with a history of pediatric disease: impact on course of life and transition into adulthood.

PURPOSE: To assess the course of life of young adults who grew up with a chronic or life-threatening disease, and to compare their course of life with that of peers from the general population. Optimal transition from pediatric to adult health care requires knowledge of the psychosocial history of patients grown up with a pediatric disease. METHODS: A total of 508 young adults from the general Dutch population and 650 patients, aged 18-30 years, participated: 348 survivors of childhood cancer, 93 patients with anorectal malformations, 72 patients with Hirschsprung's disease, 61 patients with oesophageal atresia, 76 patients with end-stage renal disease. They completed the Course of Life Questionnaire, which retrospectively assesses the achievement of developmental milestones (autonomy, psychosexual and social development), and risk behavior (antisocial behavior, substance use and gambling). RESULTS: The young adults grown up with a chronic or life-threatening disease proved to have achieved significantly fewer milestones, or at older age than their peers, in all course-of-life domains. The course of life of young adults grown up with esophageal atresia was not delayed compared with that of their peers, whereas that of survivors of childhood cancer and patients with end-stage renal disease was delayed most. CONCLUSIONS: Health care providers should help to minimize the harm for children who grow up with a chronic or life-threatening disease by encouraging parents to stimulate social contacts and autonomy. Attention should especially be directed at children and adolescents growing up with childhood cancer or with end-stage renal disease.

Quality of life in adult survivors of correction of esophageal atresia.

HYPOTHESIS: Long-term quality of life (QOL) in adults after correction of esophageal atresia (EA) is comparable with that of healthy adults. DESIGN: Outcome study with a consecutive sample and follow-up after 16 years or longer. SETTING: Pediatric surgical center (academic center) in a tertiary hospital. PATIENTS AND METHODS: A questionnaire was sent to 119 consecutive surviving adults who were treated for EA between 1947 and 1986. The questionnaire was to assess sociodemographic characteristics and generic and disease-specific QOL and contained 3 open-ended questions about the consequences of the disease in daily life. Clinical characteristics were collected from patient case notes. RESULTS: Ninety-seven (82%) of the 119 questionnaires were completed and returned. When comparing the generic QOL of patients who had EA with that of healthy subjects, we found no differences in overall physical and mental health. The presence of concomitant congenital anomalies did not influence generic QOL. A third of the patients reported that EA had had negative effects on their daily lives. Gastrointestinal symptoms such as dysphagia were most often mentioned (23%). CONCLUSION: In general, after EA correction, patients perceive their generic and disease-specific QOL to be good. The presence of concomitant congenital anomalies did not influence generic QOL. However, a third of patients reported that the disease had had negative consequences.

Esophagitis and Barrett esophagus after correction of esophageal atresia.

BACKGROUND: Gastroesophageal reflux is a frequent problem after esophageal atresia (EA) repair. Our aim was to determine the prevalence of esophagitis and Barrett esophagus more than 10 years after repair of EA. METHODS: Ninety-two patients treated between 1973 and 1985 were included in this prospective study. A questionnaire was completed by 86 patients; esophagogastroscopy was performed in 49 patients. RESULTS: Only 36 patients had no complaints at all. Thirty-one patients complained of difficulties swallowing solid food; 23 complained of heartburn. Esophagogastroscopy revealed grade 3 esophagitis in 2 patients and a macroscopic image of Barrett esophagus in 2. Histology showed esophagitis in 30 patients, gastric metaplasia in 3, and no intestinal metaplasia (Barrett esophagus). CONCLUSIONS: For epidemiologic reasons, that is, the short interval of follow-up (10 years) and the low compliance of the study group, larger numbers are needed to decide if routine long-term endoscopic screening after repair of EA is necessary. For now, it cannot yet be recommended. The prevalence of symptoms of gastroesophageal reflux disease in this study group is higher than that in the general population, but we found no severe complications of gastroesophageal reflux in the pediatric age group.

Gastroesophageal reflux: prevalence in adults older than 28 years after correction of esophageal atresia.

OBJECTIVE: To study the incidence of gastroesophageal reflux (GER)related complications after correction of esophageal atresia (EA). SUMMARY BACKGROUND DATA: The association of EA and GER in children is well known. However, little is known about the prevalence of GER and its potential complications in adults who have undergone correction of EA as a child. METHODS: Prospective analysis of the prevalence of GER and its complications over 28 years after correction of EA by means of a questionnaire, esophagogastroscopy, and histologic evaluation of esophageal biopsies. RESULTS: The questionnaire was returned by 38 (95%) of 40 patients. A quarter of the patients had no complaints. Swallowing solid food was a problem for 13 patients (34%), and mashed foods for 2 (5%). Heartburn was experienced by 7 patients (18%), retrosternal pain by 8 (21%). However, none of the patients were using antireflux medication. Twenty-three patients (61%) agreed to undergo esophagogastroscopy, which showed macroscopic Barrett esophagus in 1 patient, which was confirmed by histology. One patient developed complaints of dysphagia at the end of the study. A squamous cell esophageal carcinoma was diagnosed and treated by transthoracic subtotal esophagectomy. CONCLUSIONS: This study shows a high incidence of GER-related complications after correction of EA, but it is still very disputable if all EA patients should be screened at an adult age.

Esophageal atresia: historical evolution of management and results in 371 patients.

BACKGROUND: It has been more than 50 years since the first successful surgical reconstruction of esophageal atresia was performed in The Netherlands. We reviewed the historical changes in management and treatment results of patients born with esophageal atresia. METHODS: We developed and analyzed a database of 371 consecutive patients treated for esophageal atresia in our center between 1947 and 2000. RESULTS: The mean birthweight decreased from 2,723 g (1947 to 1968) to 2,494 g (1994 to 2000), the mean gestational age decreased from 39 weeks (1947 to 1968) to 37 weeks (1994 to 2000). The number of patients with associated congenital malformations increased from 34% (1947 to 1968) to 66% (1994 to 2000). Most patients underwent primary repair of their atresia. Clinically significant tracheomalacia was present in 34 of 269 patients (13%). Gastroesophageal reflux was present in 90 of 277 patients (33%). Mortality decreased from 61% (1947 to 1968) to 11% (1994 to 2000). CONCLUSIONS: The patients who are treated nowadays for esophageal atresia in a pediatric surgical center are born earlier, weigh less, and have more associated anomalies than those treated 50 years ago. Still, the mortality rate is much lower thanks to earlier diagnosis, better supportive care and improved surgical techniques. Therefore, further significant reduction will be difficult to achieve.
