The polymerase chain reaction: from functional genomics to high-school practical classes.

After a decade of intensive use as an in vitro alternative to cloning DNA, PCR is now well established as the default method for DNA and RNA analysis. Recent developments have consolidated this position by the introduction of more robust formats, improvements in thermal cyclers and labelling and detection methods. The trend is towards increasing automation, although comparatively few diagnostic kits based on PCR are in wide use. At the same time the applications of PCR are being extended with modifications such as long, accurate PCR and arrayed oligonucleotides or expressed sequences.

Mild closed-head injury in children and adolescents: behavior problems and academic outcomes.

The issue of whether mild head injuries (HIs) in children cause behavior problems and poor scholastic performance is controversial. This study included 119 children (range = 8-16 years old) with HI, 114 with other injuries, and 106 with no injury (NI). Behavioral functioning was assessed with the Child Behavior Checklist; academic functioning, with school grades and standardized testing. Higher T scores were found for both injury groups versus NI participants on preinjury behavioral status. All 3 groups' behavioral scores decreased relative to baseline at 1 year. HI and NI groups did not differ in school grades or achievement testing either pre- or postinjury. These results are consistent with the conclusion that head injury of the mildest type does not increase the probability of new overt behavioral or academic problems.

Congenital hemiplegia in children at school age: assessment of hand function in the non-hemiplegic hand and correlation with MRI.

The aim of this study was to evaluate whether children with congenital hemiplegia show abnormal hand function on the non-hemiplegic side and whether this, if present, can be related to the type and extent of brain lesions on MRI. Twenty-two children with congenital hemiplegia of age ranging between 4.8 and 12.3 years, were assessed with a clinical and MRI assessment. Clinical assessment included a structured neurological examination, assessment of hand grips and the Movement Assessment Battery for Children which also includes one item assessing speed and accuracy in each hand. The results showed that 64% of the children studied showed some degree of functional impairment of the non-hemiplegic hand. Manual dexterity 1 from the Movement ABC was, in our experience, a more sensitive tool to detect minor functional abnormalities than the evaluation of hand grips. The severity of the impairment on the non-hemiplegic side was not significantly related to the severity of impairment in the hemiplegic hand (p > 0.05). In contrast, a significant association was found with the site of lesions as hand function in the non-hemiplegic hand was always normal in children with unilateral lesion and abnormal in the ones with bilateral parenchymal lesions (p < 0.05). Children with predominantly unilateral lesions but with bilateral ventricular dilatation or periventricular changes showed more variable results.

Long-term developmental outcome of infants with iron deficiency.

BACKGROUND: Iron-deficiency anemia has been associated with lowered scores on tests of mental and motor development in infancy. However, the long-term developmental outcome of infants with iron deficiency is unknown, because developmental tests in infancy do not predict later intellectual functioning. METHODS: This study is a follow-up evaluation of a group of Costa Rican children whose iron status and treatment were documented in infancy. Eighty-five percent (163) of the 191 children in the original group underwent comprehensive clinical, nutritional, and psychoeducational assessments at five years of age. The developmental test battery consisted of the Wechsler Preschool and Primary Scale of Intelligence, the Spanish version of the Woodcock-Johnson Psycho-Educational Battery, the Beery Developmental Test of Visual-Motor Integration, the Goodenough-Harris Draw-a-Man Test, and the Bruininks-Oseretsky Test of Motor Proficiency. RESULTS: All the children had excellent hematologic status and growth at five years of age. However, children who had moderately severe iron-deficiency anemia as infants, with hemoglobin levels less than or equal to 100 g per liter, had lower scores on tests of mental and motor functioning at school entry than the rest of the children. Although these children also came from less socioeconomically advantaged homes, their test scores remained significantly lower than those of the other children after we controlled for a comprehensive set of background factors. For example, the mean (+/- SD) adjusted Woodcock-Johnson preschool cluster score for the children who had moderate anemia in infancy (n = 30) was 448.6 +/- 9.7, as compared with 452.9 +/- 9.2 for the rest of the children (n = 133) (P less than 0.01); the adjusted visual-motor integration score was 5.9 +/- 2.1, as compared with 6.7 +/- 2.3 (P less than 0.05). CONCLUSIONS: Children who have iron-deficiency anemia in infancy are at risk for long-lasting developmental disadvantage as compared with their peers with better iron status.

The psychological and social functioning of 14 children and 12 adolescents after Ilizarov leg lengthening.

We studied the psychological and social impact of the Ilizarov leg lengthening procedure in 26 patients (aged 6-17 years), who had completed the treatment at least 2 months previously. Measurements of depression and anxiety were performed preoperatively and at follow-up. Questions about functioning at school, daily life activities and treatment-related experiences were answered by the patient and his/her parents. The school or work results showed no significant decline during the lengthening procedure. Serious sleeping problems occurred during the procedure. There was no subjective improvement in physical skill after the procedure and almost one-fourth of the children still had complaints about their leg. We conclude that the Ilizarov procedure caused no serious psychological disturbances.

The analysis of a pre-homosexual child with a twelve-year developmental follow-up.

This paper presents clinical material from the three-year psychoanalysis of an eight-year-old boy and his fight to assume his normal gender-defined self-identity. It also outlines a twelve-year follow-up when the patient returned for consultation during crucial periods in his life. The analysis illustrates the psychodynamics underlying the anxieties that led to gender-defined self-identity confusion. The child's attempts to appease an engulfing mother resulted in severe separation anxiety and a tendency toward a resolution of his intrapsychic conflicts by engaging in homosexual acts. Mother presented significant obstacles to the treatment, which continued even as the child began to adopt masculine interests. Father, who was dominated by his wife, was distant, unavailable, and ashamed of his son's effeminate tendencies. He could not express pride in the boy's considerable intellectual abilities and was unable to provide a strong male identity figure. The parents refused to seek psychotherapy for themselves which would have benefited their son. Despite these obstacles, the child's progress in analysis was seen in (1) his ability to function at school, (2) the disappearance of his transvestism, (3) the decrease and near-obliteration of feminine behavior, (4) improvement in aggression control, and (5) a lessening of narcissistic overinvestment in the self. Also, his fears of death and his most prominent anxieties were overcome. What remained was a search for the father, which manifested itself, in his middle to late adolescence, in an attraction toward men. The men he chose to pursue, however, were not homosexuals, and this revealed the patient's ambivalence about embarking on homosexual relationships. At the twelve-year follow-up I encouraged the patient to pursue referrals to an adult analyst. My experience is in child analysis, and he did not seem ready to modify the good child/adult therapeutic imago that was sustaining him. In the subsequent four years, there has been no further contact with the patient.

Phenelzine efficacy in refractory social anxiety disorder: a case series.

Several effective treatments for social phobia are now available, notably cognitive behavioural therapy and some antidepressant medications. Controlled trials indicate that 25-45% of patients fail to respond to the initial treatment. To my knowledge, nothing has yet been published on the treatment of refractory cases. Phenelzine is effective in social phobia, and no treatment has been shown to be superior to phenelzine. Hence, phenelzine is a reasonable option for patients unresponsive to other treatments. This report presents the results of naturalistic, open-label phenelzine treatment of a series of seven consecutive, previously unresponsive patients treated with a mean dose of phenelzine 66 mg. Six patients were classified as responders according to Clinical Global Impression (CGI) ratings. Some experienced dramatic improvement and regained ability to function in school or work. Two patients experienced re-emergence of social phobia while on maintenance therapy. The majority of patients had a sustained response and elected to stay on the medication. There were no serious adverse events. Two patients discontinued due to side-effects. The drawbacks of phenelzine therapy may be more than outweighed by its potential utility in relieving social anxiety disorder. Phenelzine appears to be effective in treating social phobia that has been unresponsive to other treatments. No patient should be considered treatment resistant without being offered a trial of phenelzine.

Construction of an Infant Neurological International Battery (Infanib) for the assessment of neurological integrity in infancy.

In this article, we describe the construction of an instrument for the assessment of the neurological integrity of infants. In a follow-up program for infants from the neonatal intensive care unit, 365 evaluations of 308 infants were made by using a 32-item battery with items from four methods. Factor analyses were used for data analyses, which yielded a 20-item instrument with five factors. We named the instrument the Infant Neurological International Battery (Infanib). The Infanib has sufficient reliability for clinical and research purposes. We have formed scoring sheets, which permit clinical use of the instrument. Cut points are recommended for the separation of infants with normal, transiently abnormal, and abnormal neurologic development. The quantified scoring system enables comparison of infants on item scores, subscores (factor scores), and total scores. It also permits entry of these scores in the computer so that more complex descriptions are possible of the relationship of the neurological assessment of infants both to earlier (eg, birth) and later variables (eg, cerebral palsy, cognitive function, and school performance).

The British Child and Adolescent Mental Health Survey 1999: the prevalence of DSM-IV disorders.

OBJECTIVE: To describe the prevalence of DSM-IV disorders and comorbidity in a large population-based sample of British children and adolescents. METHOD: Using a one-phase design, 10,438 children were assessed using the Development and Well-Being Assessment (DAWBA), a structured interview with verbatim reports reviewed by clinicians so that information from parents, teachers, and children was combined in a manner that emulated the clinical process. The authors' analysis examined comorbidity and the influence of teacher reports. RESULTS: The overall prevalence of DSM-IV disorders was 9.5% (95% confidence interval 8.8-10.1%), but 2.1% of children were assigned "not otherwise specified" rather than operationalized diagnoses. After adjusting for the presence of a third disorder, there was no longer significant comorbidity between anxiety and conduct disorder or attention-deficit/hyperactivity disorder (ADHD), or between depression and oppositional defiant disorder. A comparison of the disorders in children with and without teacher reports suggested that the prevalence of conduct disorders and ADHD would be underestimated in the absence of teacher information. CONCLUSIONS: Roughly 1 in 10 children have at least one DSM-IV disorder, involving a level of distress or social impairment likely to warrant treatment. Comorbidity reported between some childhood diagnoses may be due to the association of both disorders with a third. Diagnoses of conduct disorder and ADHD may be missed if information is not sought from teachers about children's functioning in school.

Development of a quality-of-life index for pediatric inflammatory bowel disease: dealing with differences related to age and IBD type.

BACKGROUND: A child- and adolescent-generated IBD quality-of-life index was designed to be descriptive (to be used to assess the overall impact of IBD on individual patients), and evaluative (to be used as an outcome measure in clinical trials). METHODS: Item-generation and item-reduction interviews with 82 patients with IBD aged 8 to 17 years (61 with Crohn's disease, 21 with ulcerative colitis; 36 girls, 45 boys) generated a list of ways in which their lives were affected by IBD. These issues were incorporated into an item-reduction questionnaire, which was administered to 117 patients (87 Crohn's disease, 30 ulcerative colitis). Patients indicated on a visual analog scale how important an item was to them and how often it bothered them. Mean and median importance-plus-frequency scores for each issue were calculated for the entire group and among patients in subgroups according to age and IBD type. RESULTS: Ulcerative colitis and Crohn's disease affect the lives of children and adolescents differently. Bowel symptoms are more troubling and disabling to patients with ulcerative colitis, whereas systemic symptoms and body image concerns are greater for patients with Crohn's disease. The impact of Crohn's disease on ability to function in school and leisure activities is greater. Worries about future health problems and about the effects of IBD on the family are shared. Crohn's disease and ulcerative colitis trigger emotional responses of unfairness and frustration, but anger and embarrassment are more prevalent in ulcerative colitis. Disparities between age groups are fewer and less marked than those between types of IBD. CONCLUSION: In selection of items to be retained in a pediatric IBD quality-of-life measure, the variation in concerns with disease type must be considered. A single index to assess IBD-related quality of life must include items of major importance to one subgroup of patients, even if not important to all. Alternately, a core of common concerns could be supplemented by disease-specific modules, thereby increasing the content validity of the tool for all patients.

Value of a shortened questionnaire in the description of asthma in 10-12-year-old pupils.

Asthma is a common and severe chronic disease in children influencing their quality of life and functioning at school. A 5-item asthma-screening instrument was developed and tested in 1052 children aged 10-12 years. Questionnaires were completed by parents and children separately and data were compared. Children reported less to be diagnosed by a medical doctor as having asthma compared with their parents, although children reported more to have certain asthma symptoms. No difference in prevalence of asthma was found between children and parents' answers. The absolute agreement for the scale was 92% and a good kappa agreement was found. Recoding the "don't know"-answers in "no"-answers resulted in a 4% misclassification. The short 5-item asthma screening tool can be valuable in the categorization of a subgroup of children likely to suffer from asthma in a survey. Recoding 'don't know'-answers to 'no'-answers is justified in large samples

Specific intellectual deficits in children with early onset diabetes mellitus.

27 children with early onset (less than 4 years) diabetes (EOD), 24 with late onset (greater than 4.0 years) diabetes (LOD), and 30 sibling controls were compared in their performance on tests of intellectual functioning and school achievement. The results indicated that children with EOD, particularly girls, scored lower than the other groups of diabetic children and siblings on tests of visuospatial but not verbal ability. Many of the children with EOD were also having difficulty at school, and a number were currently receiving special education. Diabetic children with earlier onset had more hypoglycemic convulsions than those with later onset. Regression analyses revealed that duration of illness, age of onset, and hypoglycemic convulsions significantly predicted spatial ability.

Intellectual functions of patients with childhood-onset epilepsy.

The intellectual functions of 64 epileptic patients who had had an initial evaluation between five and 16 years of age, including the WISC, were re-evaluated after a period of at least five years. In general the seizure states had improved, and 50 per cent were in remission for between two and eight years. All but four were still taking at least one anticonvulsant drug. WISC IQ estimates showed a slight decrease. Verbal and performance areas could be differentially affected, and a gain in one could be offset by a loss in the other, so the Full-scale IQ might not be a reliable measure of day-to-day performance. Those whose seizures remained uncontrolled had a statistically significant decrease in performance IQ, whereas in general it was stable or increased for patients in remission. There was evidence that decreased IQ indicated slower mental growth rather than loss of previously acquired function. Phenobarbital but not phenytoin levels were inversely correlated with IQ, suggesting that the upper limit of the 'therapeutic range' of phenobarbital may already be toxic with regard to learning abilities. To optimize an epileptic child's functioning in school and to prevent long-term intellectual problems, it is advisable that IQ testing should be part of the routine initial evaluation, and that drug levels should be checked at regular intervals.

Divorced parents in family therapy in a residential treatment setting.

Divorced parents are required to participate together in the family therapy of their child placed in a residential treatment center. Different sources of resistance and treatment techniques are identified and discussed through a theoretical analysis and case study material. The therapy of these fractured families contributed to an elimination of recidivism and, according to followup reports, to significant and sustained improvement in the children's functioning in school, home, and community activities.

Asthma knowledge, roles, functions, and educational needs of school nurses.

In October 1997, 790 school nurses in Maryland and the District of Columbia were surveyed to determine their attitudes, knowledge, and beliefs about asthma. Results for 550 (70%) nurses indicated school nurses possess a generally appropriate level of knowledge concerning asthma, and most asthma myths have been replaced with knowledge. However, school nurses also have varied responsibilities that affect their ability to provide health education and support services to children with asthma at school. Little time is available for a proactive role. Concerns about the criteria and follow-up for delegating medication administration within the school setting were reported. A lack of communication existed with parents about the child's asthma. Open communication between school nurses and the family is recommended to establish a partnership and improve asthma management outcomes. In addition, school policies and procedures should be updated to meet the demands of children with asthma.

Abnormal cognitive function in treated congenital hypopituitarism.

AIMS: To assess cognitive function in school age children with congenital pituitary hormone deficiency (PHD). METHODS: Ten children with PHD (aged 6.0-15.6 years, mean 11.5 years) and sibling controls (aged 8.7-14.9 years, mean 12.1 years) were assessed using the Wechsler Intelligence Scale for Children (WISC-III UK). RESULTS: The patients' full scale IQ scores were all below average (mean 75, 95% CI 70-80), but were not significantly different to those of sibling controls (mean 82, 95% CI 75-89). There was no difference in verbal IQ between patients and siblings, but performance IQ was significantly reduced (mean 75, 95% CI 68-82 in patients; mean 88, 95% CI 80-96 in sibling controls). The reduced performance IQ reflected a poorer performance in tasks assessing perceptual organisational skills. CONCLUSIONS: Data suggest that children with PHD have an IQ that is below average when compared to the population norm and a reduced performance IQ when compared to sibling controls. This may reflect abnormal brain development or could be linked to the impact of hypoglycaemia or low thyroxine concentrations in early life. This information is of value when counselling parents and planning a child's care and education, although further, more extensive studies of patients and siblings are required.
