Abstract
BACKGROUND Standardised measures of behaviour have failed to detect short term improvement in children with autism following treatment with secretin. However, it is possible that standardised measures are insensitive to dimensions of child behaviour that are nonetheless detectable by parents. AIM To determine the ability of parents of children with autism to guess, under double blind conditions, whether their child had received secretin or placebo. METHODS 2x2 crossover randomised blinded study, comparing the effect of synthetic human secretin 2 U/kg to placebo (saline). Sixty two children with autism (aged 43-103 months) were randomly allocated to two groups: group 1 received placebo, followed six weeks later by secretin, and group 2 received secretin followed by placebo. At the conclusion of the study, parents were asked to guess their child's group assignment. RESULTS Twenty seven families guessed their child's group assignment correctly and 27 guessed incorrectly. In 48 instances, parents based their guess on perceived improvement; in six cases, parents based their guess on perceived deterioration. Six families saw no difference after either infusion, and offered no guess. One family dropped out after the first infusion, and one family was lost to follow up after the second infusion. CONCLUSION In a controlled setting, parents of young children with autism are unable to distinguish the short term behavioural effects of secretin from placebo.

Abstract
AIMS To examine the effect of a single dose of human synthetic secretin (HSS) on behaviour and communication in children with autism spectrum disorder (ASD) using an objective measure of communication and social reciprocity and standardised rating scales. METHODS Randomised, crossover, double blind, and placebo controlled trial of a single intravenous dose of human synthetic secretin (HSS) 2 CU/kg. The 62 subjects (3-8 years) were assigned to group 1 (saline placebo/HSS) or group 2 (HSS/saline placebo). Diagnosis was confirmed by ADI-R (Autism Diagnostic Interview-Revised) algorithm. Severity of symptoms was rated using the CARS (Childhood Autism Rating Scale). Outcome measures included Communication and Symbolic Behavior Scale (CSBS), Ritvo Real-life Rating Scale, weekly Global Rating Scale (GBRS) by parents and teachers, and daily log of gastrointestinal symptoms. The communication subscale of the CSBS, specifying communication function, reciprocity, and social-affective signalling was videotaped and scored by a blinded, trained observer. RESULTS Sixty one children completed the study. After randomisation, there were no significant differences in gender, race, age, and parent and teacher GBRS and Ritvo Scale between the two groups. Compared with placebo, secretin treatment was not associated with significant improvement of CSBS standard scores from baseline to 2 or 4 weeks post-infusion. Five children showed clinical improvement in standard scores: two after HSS and three after placebo. There were no significant changes in gastrointestinal symptoms after HSS or saline placebo. CONCLUSIONS A single dose of intravenous human secretin is not effective in changing behaviour and communication in children with ASD when compared to placebo.

Abstract
BACKGROUND Inhalation of carbon dioxide (CO(2)) has been shown to produce more anxiety in patients with panic disorder (PD) than in healthy comparison subjects or patients with most other psychiatric illnesses tested, although premenstrual dysphoric disorder (PMDD) may be an exception. Several reasons have been proposed to explain CO(2) breathing effects in PD. We examined differences in respiratory response to CO(2) breathing in 4 groups to address these issues. METHODS Patients with PD (n = 52), healthy controls (n = 32), patients with PMDD (n = 10), and patients with major depression without panic (n = 21) were asked to breathe 5% and 7% CO(2). Continuous measures of respiratory physiological indices were made. RESULTS Carbon dioxide breathing produced the expected increases in all 4 respiratory variables measured. More patients with PD and PMDD had panic attacks than did controls or patients with major depression. Subjects who experienced panic during 5% or 7% CO(2) inhalation had the most extreme increases regardless of diagnostic group. Among patients with PD, baseline end-tidal carbon dioxide levels were significantly lower in those who subsequently had a panic attack during 5% CO(2) breathing than those who did not. CONCLUSIONS Although CO(2) breathing causes a higher rate of panic attacks in patients with PD than other groups (except PMDD), the physiological features of a panic attack appear similar across groups. Once a panic attack is triggered, minute ventilation and respiratory rate increase regardless of whether the subject carries a PD diagnosis. These findings are compatible with preclinical fear conditioning models of anxiogenesis.

Abstract
A triaxial model for autistic spectrum disorder (ASD) is presented, incorporating age, degree of intelligence, and severity of autistic features. As the name implies, ASD can vary in degree of expression from minimal to profound. Furthermore, the symptoms of ASD change in predictable ways with the passage of time. For example, echolalia during early childhood may be replaced by verbal literalism and difficulty with verbal humor during later childhood or adolescence. The prognosis for children with ASD is governed by the joint impact of the degree of expression of ASD and the degree of developmental delay, if any. All combinations of ASD and intellect are possible (ie, severe ASD plus severe mental retardation, severe ASD plus normal general intelligence, and so forth). The relationship among these 3 parameters-severity of ASD, level of general intelligence, and change in symptom expression over time, is represented schematically as a 3-dimensional graph. The utility of this graph as a counseling tool, and as the basis for future research on the prognosis of ASD are discussed.

Abstract
OBJECTIVES To compare language development in infants and young children with human immunodeficiency virus (HIV) infection to language development in children who had been exposed to HIV but were uninfected, and (among subjects with HIV infection) to compare language development with cognitive and neurologic status. DESIGN Prospective evaluation of language development in infected and in exposed but uninfected infants and young children. SETTING Pediatric Infectious Disease Clinic, State University of New York-Health Science Center at Syracuse. SUBJECTS Nine infants and young children infected with HIV and 69 seropositive but uninfected infants and children, age 6 weeks to 45 months. RESULTS Mean Early Language Milestone Scale, 2nd edition (ELM-2) Global Language scores were significantly lower for subjects with HIV infection, compared with uninfected subjects (89.3 vs 96.2, Mann-Whitney U test). The proportion of subjects scoring >2 SD below the mean on the ELM-2 on at least one occasion also was significantly greater for subjects with HIV infection, compared with uninfected subjects (4 of 9 infected subjects, but only 5 of 69 uninfected subjects; Fisher's exact test). Seven of the 9 subjects with HIV infection manifested deterioration of language function. Four manifested unremitting deterioration; only 1 of these 4 demonstrated unequivocal abnormality on neurologic examination. Three subjects with HIV infection and language deterioration showed improvement in language almost immediately after the initiation of antiretroviral drug treatment. Magnetic resonance imaging or computed tomography of the brain were performed in 6 of 7 infected subjects with language deterioration, and findings were normal in all 6. ELM-2 Global Language scaled scores showed good agreement with the Bayley Mental Developmental Index or the McCarthy Global Cognitive Index (r = 0. 70). Language deterioration, or improvement in language after initiation of drug therapy, coincided with or preceded changes in global cognitive function, at times by intervals of up to 12 months. CONCLUSIONS Language deterioration occurs commonly in infants and young children with HIV infection, is seen frequently in the absence of abnormalities on neurologic examination or central nervous system imaging, and may precede evidence of deterioration in global cognitive ability. Periodic assessment of language development should be added to the developmental monitoring of infants and young children with HIV infection as a means of monitoring disease progression and the efficacy of drug treatment.

Abstract
The objective of this study was to examine associations in youth between antisocial behavior and cardiovascular profile. Younger brothers of adjudicated delinquents (N = 120) received a standardized psychiatric assessment and an assessment of three factors often studied in behavioral cardiology research: family history of hypertension, resting blood pressure, and obesity. As a group, relative to population norms, these youth exhibited signs of obesity and elevated blood pressure, with 30% of the sample appearing clinically obese and 24% having a blood pressure above the 90th percentile for national norms in their age cohort. Within the sample, score on the Child Behavior Checklist (CBCL) Delinquency scale correlated with blood pressure (r = .29-.34) and an index of obesity, weight/height3 (r = .20). Further, scores on the CBCL Delinquency, Aggression, and Externalizing scales were elevated in boys with a positive family history of hypertension. Among boys at risk for delinquency, disruptive psychopathology relates to factors often studied in behavioral cardiology research. Relationships between risk factors for ischemic cardiovascular disease and hostile behavior may be manifested with measures of disruptive psychopathology.

Abstract
OBJECTIVE This study examined the cross-sectional association between platelet membrane serotonin 2A (5-HT2A) receptor variables in children and characteristics of their parents that place these children at risk for antisocial behavior. METHOD As part of a larger prospective study investigating predictors of antisocial behavior, 38 younger brothers of convicted delinquents provided platelet samples; samples from 34 boys (mean age=8.3 years) were usable. The authors determined the density (Bmax) and affinity (Kd) of platelet membrane 5-HT2A receptors by using [3H]lysergic acid diethylamide. They also measured parental characteristics related to serotonergic dysfunction in prior studies, the quality of parent-child interactions, and psychiatric profiles of the boys who provided platelets. RESULTS Bmax was significantly lower in boys whose parents had histories of substance abuse or incarceration. Bmax was also inversely related to harsh parenting; boys raised in environments characterized by frequent parental physical punishment and anger had a significantly lower Bmax. Bmax was not related to boys' disruptive behavior. CONCLUSIONS In boys at risk for antisocial behavior, the density of 5-HT2A receptors on platelets is inversely related to parental factors known to place youth at risk for antisocial behavior.

Abstract
OBJECTIVE To describe the epidemiology of newborn seroprevalence for human immunodeficiency virus (HIV) in a predominantly white, nonurban population, and to determine the factors associated with enrollment at a regional pediatric acquired immunodeficiency syndrome (AIDS) center serving that population. DESIGN Retrospective case series of children enrolled at a regional pediatric AIDS center during a 6-year period and comparison with universal blind newborn screening data collected by the state of New York during the same time interval. SETTING The Pediatric AIDS Center at State University of New York-Health Science Center at Syracuse, which serves as the only source of HIV-related pediatric care for children in a 16-country region of upstate New York totaling 1.8 million population. RESULTS One hundred thirty-nine HIV-seropositive infants were born in the region during the 6-year study period; complete blind screening data were available for 138. Sixty-five (47%) of these infants were white. Thirty-nine (28%) of 138 had been enrolled at the Pediatric AIDS Center within the first 90 days of life. An additional 22 (16%) were enrolled at older than 90 days of life. The remaining 77 (56%) have never been seen at the center and are presumed to be unidentified. County enrollment rates varied from 0% to 100% and correlated with percent nonwhite births (r = .58; 95% confidence interval, 0.04-0.86). Children in outlying counties were at greater risk for nonenrollment than children from Onondaga County (site of the Pediatric AIDS Center) (adjusted relative risk, 1.38; 95% confidence interval, 1.05-1.85). White infants residing outside of Onondaga County were at the greatest risk of nonenrollment; of 50 seropositive white infants residing outside of Onondaga County, only 7 (14%) were enrolled at the center within the first 90 days of life. CONCLUSIONS Local demographic factors can skew the racial distribution of HIV-seropositive infants dramatically compared with the national experience. White race and residence in counties away from the medical center each constituted risk factors for nonenrollment at the Pediatric AIDS Center. The epidemiology of HIV in this predominantly white, rural population, coupled with physician practices, probably contributed to low identification and enrollment rates. As the AIDS epidemic spreads into similar populations elsewhere, HIV infection in pregnant women or newborn infants is likely to become progressively harder to detect, unless universal screening is adopted.

Abstract
OBJECTIVES (1) To create a match-to-sample odorant discrimination task (MODT) for children and adolescents; (2) to assess whether nonolfactory factors affect olfactory performance more on an identification task than on the MODT; (3) to evaluate subjects with olfactory dysfunction; and (4) to create age-appropriate sets of odorants for use in the MODT format to test children of different ages. STUDY DESIGN We tested 75 normal children, aged 2 to 18 years, and 17 other subjects, aged 7 to 53 years, with known or suspected olfactory dysfunction, with the MODT. We compared the age trends in variability of scores on the MODT with those on an odorant identification task, using a weighted linear regression analysis. RESULTS The MODT was useful in children aged 5 years and older, but not generally in the 2- to 4-year-old children. There was an appreciable age trend in the variability of the scores on the identification task but not on the MODT. Mean MODT scores for subjects with suspected or known olfactory dysfunction were far below average. Finally, we created four sets of odorants that will likely be sensitive to age-specific changes in olfactory performance. CONCLUSIONS The MODT appears to be a suitable test instrument to assess olfaction in children aged 5 and older and is less likely to be influenced by nonolfactory factors than an identification task. According to our preliminary results, it is likely that the MODT will allow us to detect olfactory deficits in children of many ages.

Abstract
A retrospective chart review of 15 children with high-functioning autism was conducted for the years 1981 through 1992. The purpose of the study was to describe the experience of children with high-functioning autism from infancy through preadolescence. Chart data included clinic staff records, parent letters, academic program records, service records, and comments from the children themselves. The findings of this study support the proposition that children with autism who have an IQ above 70 follow a varied but improving course over time. All 15 children met the DSM-III-R criteria for autism when first evaluated. By middle elementary school, however, none of the children in this study met the DSM-III-R criteria for autism, although they continued to have various language disturbances, social skill deficits, and unique behavioral qualities.

Abstract
OBJECTIVE Patients with panic disorder are behaviorally hypersensitive to CO2 inhalation and may also be biologically hypersensitive. A report by Mathew et al. showed, however, that administration of the carbonic anhydrase inhibitor acetazolamide, which is believed to increase brain CO2 level, did not cause panic in panic disorder patients. The authors of the present study noted that respiratory frequency did not increase in the earlier experiment and wondered whether respiratory stimulation occurred during acetazolamide administration, as would be expected if CO2 level increases significantly. METHOD Ten patients with panic disorder and six normal control subjects received injections of acetazolamide, 1 g i.v., as per the Mathew et al. protocol, during breath by breath measurement of both tidal volume and frequency of respiration. RESULTS Three patients had panic attacks, one before receiving acetazolamide, one during the injection, and one 2 minutes after injection. Only the last of these attacks appeared possibly attributable to acetazolamide. None of the control subjects panicked. Neither patients nor control subjects exhibited meaningful change in tidal volume, respiratory frequency, or minute ventilation, and both groups experienced a trend toward significant decrease in overall levels of anxiety and dyspnea after acetazolamide injection. CONCLUSIONS The authors replicated the earlier finding that acetazolamide is not panicogenic in patients with panic disorder but also showed that at the dose given, there is no meaningful effect on ventilation. If acetazolamide does affect CO2 levels it does so in a way that does not stimulate ventilation. Therefore, the acetazolamide injection results of Mathew et al. and of the present study do not challenge hypotheses linking panic attacks to hypersensitive respiratory control mechanisms.

Test-retest and interobserver reliability are reported for the Early Language Milestone Scale, second edition, a language assessment tool for infants and children from birth to 36 months of age. Reliability data are presented for two scoring methods: the pass-fail method that yields a global rating of "pass" or "fail," and the point-scoring method that yields percentile scores. Both scoring methods showed good reliability. The clinical applicability of each scoring system is discussed.

Abstract
The novel anxiolytic agent buspirone has been shown to be effective in generalized anxiety disorder, but its utility in phobic disorders is less clear. We examined its efficacy in social phobia in a 12-week open trial. Twenty-one patients who met DSM-III-R criteria for social phobia and who did not respond to 1 week of single-blind placebo were treated with buspirone, and 17 completed a minimum of 2 weeks of treatment. Twelve of these 17 patients met criteria for the generalized subtype of social phobia. At week 12, 8 (47%) of the 17 patients were rated much to very much improved in social phobia symptoms on the Clinical Global Impression Scale. Of the 12 patients who were able to tolerate a dose of 45 mg/day or more, 9 (67%) were at least much improved. Significant improvement was noted on measures of social anxiety and avoidance of social situations. Ratings of generalized anxiety and depression, which were low at baseline, did not change significantly during treatment. The results suggest that buspirone may have modest efficacy in the treatment of social phobia, but confirmation in a placebo-controlled trial is required.

Abstract
A point-scoring technique for the Early Language Milestone Scale is described. Normative data based on the original 1982 cross-sectional sample and validation data based on a separate longitudinal sample are presented. Mean Early Language Milestone Scale point scores, standard deviations, and percentile equivalents for raw point scores are presented for all ages from birth to 36 months. Correlations between point scores on the Early Language Milestone Scale and scores on other standardized developmental tests such as the Stanford-Binet Intelligence Scale, the Peabody Picture Vocabulary Test, and the Illinois Test of Psycholinguistic Abilities are presented. The clinical and research advantages of this point-scoring technique are presented and compared with the original pass/fail scoring method.

Abstract
Clarity of speech normally improves throughout the first few years of life, with acquisition of complete intelligibility by 4 years of age. Delayed emergence of intelligibility, or frankly unintelligible speech, often signify the presence of a major disturbance of language, overall cognitive development, or hearing. Norms are provided for the ages by which a child should be 50%, 75%, and 100% intelligible to strangers, and a new technique for screening intelligibility of speech is described. Data validating this technique are presented, and the developmental implications of unintelligible speech are reported. The importance of screening for intelligibility of speech is emphasized, in light of the findings presented.

Abstract
Thirty-five children who had been born preterm with and without intracranial hemorrhage and weighing less than or equal to 1500 g were followed prospectively to assess neurodevelopmental outcome. The 13 children with hemorrhage were inferior to the 22 without hemorrhage in terms of birthweight, Apgar scores, health complications at and after birth, neurological integrity at age five and several scales of the McCarthy Scales of Children's Abilities. The hemorrhage group performed significantly below the standardized mean on each of the McCarthy scales, whereas the group without hemorrhage performed below the mean only in Quantitative and Memory scores. The Bayley scales at one year were not clinically sensitive to hemorrhage, but were predictive of McCarthy General Cognitive Index scores at age five. A greater proportion of children with hemorrhage have had educational difficulties and have been included in alternative school programs. Preterm, very low-birthweight children, and particularly those with intracranial hemorrhage, are at high risk for motor, perceptual and cognitive defects which underlie learning difficulties.

Abstract
Records of approximately 1,000 children seen for evaluation of developmental delay during the period July 1979 to December 1985 were reviewed; 46 children with permanent hearing loss were identified. Age at diagnosis of deafness and factors contributing to delay in diagnosis were sought. Mean age at diagnosis of profound congenital deafness was 24 months. Lesser degrees of congenital hearing loss were not diagnosed until 48 months of age. High-risk medical history or physical anomalies associated with embryologic abnormalities of the auditory system that should have triggered a prompt search for deafness went unheeded in most instances. In 40% of subjects, the author was the first to diagnose hearing loss. For two thirds of this subgroup, audiologic referral was prompted by medical, physical, or developmental findings rather than clinically evident hearing loss during physical examination. Adherence to specific historical, physical, or developmental risk criteria, regardless of the examiner's subjective impression of how well the child seems to hear, would have permitted the timely diagnosis of hearing impairment in all children in this series.

Abstract
Because of the relative frequency of speech/language delay, all infants and preschool children should undergo routine language screening as part of health care maintenance. Diagnostic evaluation of the child with speech or language delay should answer the following questions: What is the child's descriptive diagnosis (eg, hearing impaired, mentally retarded, DLD, etc.)? What is the child's etiologic diagnosis (eg, congenital viral infection, single gene disorder, birth asphyxia, etc.)? What is the appropriate intervention strategy (amplification, orally based speech therapy, total communication, "infant stimulation" program, etc.)? What is this child's long-term prognosis, to the extent that this is knowable? All children with speech or language delay should undergo formal audiologic testing, regardless of how well the child seems to hear in an office setting, and regardless of whether other disabilities are present which might independently explain the speech/language delay. Evaluation by a psychologist, a speech/language pathologist, or both should follow, with referral to an appropriate intervention program based upon the results of formal developmental testing. Additional medical evaluation (eg, CAT scan, EEG, karyotype), and genetic counseling must be determined on a case-by-case basis. Long-term follow-up should include an awareness that speech or language delay during the preschool years often signifies long-term developmental difficulties, warranting close follow-up of such children as they advance through the school age years.

Abstract
Over the past two decades, numerous suits for damages have been brought against physicians for the injury of wrongful life, or wrongful birth. Within the past 5 years, several precedents have been set that broaden the physician's legal obligation to recognize and act upon foreseeable or potentially recurrent genetic, teratogenic, or chromosomal disorders. These precedents may be expected to affect all physicians, but particularly pediatricians, because of the increased frequency of such disorders in the pediatric population.

Abstract
Disorders of voice and speech were studied in 43 survivors of Reye's syndrome (RS). During hospital convalescence 26 (60%) of 43 were aphonic, hoarse, or had other alterations of speech production. These disorders occurred in those patients with the worst severity of RS. Four patients (9% of survivors) had a persistent motor voice or speech disorder at follow-up examination 1 1/2 to five years after recovery. All of the patients have breathy, low-intensity voice quality, whereas three of the four exhibit rapid and slurred speech. These four children have no difficulty with the symbolic aspects of language and their motor voice and speech impairment cannot be ascribed to global intellectual deficit. Although other neurologic deficits are present in three of these four children, the disorders of voice and speech are the major permanent disabling handicap in our RS survivors.

Abstract
Detailed language evaluations were obtained by interviewing the parents of 191 healthy children aged 0 to 3 years, and by testing the children themselves. From these data, normative values were derived for 41 language milestones in the first 36 months of life. These values were used to construct the Early Language Milestone Scale (ELM Scale), a brief language assessment tool suitable for use by general pediatricians. Physician use of the ELM Scale in a population of 119 children considered at high risk for the presence of developmental disability yielded 97% sensitivity and 93% specificity for the ELM Scale as a detector of developmentally delayed children, when compared with more formal developmental measures as applied by a clinical psychologist or speech pathologist. Early language milestones are a sensitive indicator of developmental integrity; delayed achievement of early language milestones strongly suggests the presence of a significant underlying developmental disability. The ELM Scale may be adopted as a valid measure of developmental status among children considred at high risk for the presence of developmental disabilities.

Abstract
Forty-six children referred for developmental assessment underwent formal testing of language and intellectual development, and for each child a formal developmental quotient (FDQ) was obtained. Each child's mother was asked to provide a subjective estimate of her child's level of function, which was converted to a developmental quotient by dividing by the child's chronological age. The correlation coefficient between this derived parental developmental quotient estimate (DPDQE) and the FDQ was .85 (P less than .001). The DPDQE displayed 75% sensitivity and 100% specificity in detecting children with an FDQ of 69 or less. The DPDQE may be useful as one component of the routine office examination for preschool children.
