BACKGROUND: The American Academy of Pediatrics recommends that pediatricians provide anticipatory guidance about sexual development and sexual abuse prevention. OBJECTIVE: To examine parents' expectations, comfort level, and experience discussing sexual development and sexual abuse prevention with pediatricians. METHODS: A consecutive sample of parents presenting for care at 9 pediatric offices completed a self-administered survey. The survey included demographic information and questions related to parents' expectations, past experience, and comfort discussing normal childhood sexuality and sexual abuse prevention with their children's provider. Analyses examined relationships with parental recall of provider discussion about these topics and demographic characteristics. RESULTS: Of the 605 parents offered participation, 536 responses (89%) were analyzed. Respondents were 83% mothers, 62% white, 23% Hispanic, 7% African American, 6% Asian, 2% 'other,' and 65% college graduates. Nearly all respondents (98%) indicated pediatricians should discuss normal sexuality, and 96% indicated physicians should discuss sexual abuse prevention. Most parents (77%) indicated both the parent and the doctor are responsible for introducing these topics. Over 90% of parents reported that they were comfortable discussing these topics. Only 45% of respondents reported their child's pediatrician had discussed normal sexuality, and 29% had discussed sexual abuse prevention. Logistic regression modeling found the highest rates of discussion for normal sexuality were among parents with older children and the highest rates of discussion for child sexual abuse prevention topics were for mothers and those with older children. CONCLUSIONS: Pediatricians can discuss normal sexuality and sexual abuse prevention without fear of alienating parents. [ABSTRACT FROM AUTHOR]

Abstract Background Fabry disease is an X-linked lysosomal storage disorder that results from a deficiency of the enzyme α-galactosidase A. Fabry disease is present in 4–5% of men with unexplained left ventricular hypertrophy or cryptogenic stroke. As enzyme replacement therapy is now more widely available, it is important to recognise the signs and symptoms of the disease and establish the diagnosis so that early treatment can be started before irreversible organ damage occurs. Case Presentation A previously fit and well 32-year-old Caucasian male presented with multisystem dysfunction including renal impairment. Although he had no suggestive symptoms, a diagnosis of Fabry disease was first established on a native renal biopsy. This was confirmed by enzymatic testing and subsequent genetic analysis that revealed a potentially new pathogenic variant. Conclusions This case highlights the importance both of Fabry disease as a differential diagnosis in patients with renal impairment in the context of multi-system disease and also of adequate tissue sampling for electron microscopy when performing native renal biopsies.

Polypharmacotherapy is an ever-increasing issue with an ageing patient population. Anticholinergic medications make up a large proportion of patient medication but cause significant side effects, contributing to well-documented issues within the older population and in hospital medicine. This review explores the documented impact of anticholinergic burden in older surgical patients on postoperative delirium, infection, length of stay and readmission, urinary retention, ileus and mortality. It also highlights the need for further high-quality research into anticholinergic burden management among older surgical patients to further impact practice and policy in the area.

The prevalence of obesity among youth in the USA is currently >18% with projections that more than half of today's children will be obese as adults. The growth trajectory of children more likely to become obese is determined by weight in earliest childhood, and childhood body mass index (BMI) tracks through adolescence and adulthood. Childhood consequences of obesity include increased risk of asthma, type 2 diabetes mellitus, orthopedic disorders, and reduced academic performance. Health implications of obesity in adulthood include premature coronary artery disease, hypertension, type 2 diabetes, stroke, and certain cancers, contributing to the leading causes of adult mortality. Early childhood obesity is influenced by prenatal exposure to maternal obesity and environmental obesogens, and is associated with poverty, food insecurity, and poor nutritional quality. New strategies for primordial prevention of early childhood obesity require focusing attention on growth parameters during the first 2 y of life, with support for increasing the duration of breastfeeding, and improvements in dietary quality and availability, particularly the reduced consumption of added sugars. Reducing the prevalence of obesity among adolescent females and reducing exposure to environmental obesogens may reduce the prevalence of transgenerational obesity. The reduction of early childhood obesity could improve population health, quality of life, and longevity throughout the life course., (Copyright © The Author(s) on behalf of the American Society for Nutrition 2020.)

Objectives: Competence in point-of-care ultrasound is recommended/mandated by several critical care specialties. Although doctors commonly attend point-of-care ultrasound short-courses for introductory training, there is little follow-up data on whether they eventually attain competence. This study was done to determine the impact of point-of-care ultrasound short-courses on point-of-care ultrasound competence., Design: Web-based survey., Setting: Follow-up after point-of-care ultrasound short-courses in the Asia-Pacific region., Subjects: Doctors who attended a point-of-care ultrasound short-course between December 2015 and February 2018., Interventions: Each subject was emailed a questionnaire on or after 6 months following their short-course. They were asked if they had performed at least 30 structured point-of-care ultrasound scans and/or reached point-of-care ultrasound competence and their perceived reasons/challenges/barriers. They were also asked if they used point-of-care ultrasound as a clinical diagnostic aid., Measurements and Main Results: The response rate was 74.9% (182/243). Among the 182 respondents, only 12 (6.6%) had attained competence in their chosen point-of-care ultrasound modality, attributing their success to self-motivation and time management. For the remaining doctors who did not attain competence (170/182, 93.4%), the common reasons were lack of time, change of priorities, and less commonly, difficulties in accessing an ultrasound machine/supervisor. Common suggestions to improve short-courses included requests for scanning practice on acutely ill ICU patients and prior information on the challenges regarding point-of-care ultrasound competence. Suggestions to improve competence pathways included regular supervision and protected learning time. All 12 credentialled doctors regularly used point-of-care ultrasound as a clinical diagnostic aid. Of the 170 noncredentialled doctors, 123 (72.4%) reported performing unsupervised point-of-care ultrasound for clinical management, either sporadically (42/170, 24.7%) or regularly (81/170, 47.7%)., Conclusions: In this survey of doctors attending point-of-care ultrasound short-courses in Australasia, the majority of doctors did not attain competence. However, the practice of unsupervised point-of-care ultrasound use by noncredentialled doctors was common. Further research into effective strategies to improve point-of-care ultrasound competence is required.

Inquiry-based learning (IBL) activities are complementary to the processes of laboratory discovery, as both are focused on producing new findings through research and inquiry. Here, we describe the results of student surveys taken pre- and postpractical to an IBL undergraduate practical on PCR. Our analysis focuses primarily student perceptions of knowledge acquisition and their ability to troubleshoot problems. The survey results demonstrate significant self-reported gains in knowledge related to DNA structure and PCR, and an increase in confidence with "troubleshooting problems during scientific experiments." We conclude that the IBL-based approach that combines PCR primer design with wet laboratory experimentation using student-designed primers, provides students a sense of confidence by imparting workplace and research skills that are integral to diverse forms and applications of laboratory practices., (© 2015 The International Union of Biochemistry and Molecular Biology.)

Background: Although anthracycline therapy is invaluable for treating neoplastic disorders, morbidity includes severe cardiomyopathy that leads to heart transplantation. This multicenter study describes the course of children who experienced anthracycline cardiomyopathy (ACM) and who subsequently required heart transplantation., Methods: We reviewed transplant databases/registries at 4 pediatric heart transplant centers to identify children with ACM who were listed for heart transplantation. We reviewed medical records to determine cancer therapy, clinical course, and outcome., Results: Eighteen patients were listed, and 17 underwent transplantation. Mean age at cancer diagnosis was 6.0 years (SD, 3.7). The mean anthracycline dose was 361 mg/m2 (SD, 110). The median time from cancer diagnosis to listing for heart transplantation was 9.2 years (range, 0.4-15.2 years). Six transplantations were performed in patients who had disease-free intervals of <5 years. Two patients were lost to follow-up, and 8 are alive at 4.9 years (SD, 2.0; range, 1.3-7.4 years) after transplantation. Seven patients died at 4.7 years (SD, 2.0; range, 1.2-7.1 years) after transplantation. One patient had recurrent cancer. One-, 2- and 5-year survivals were 100%, 92%, and 60%, respectively., Conclusions: Cardiomyopathy that progresses to the need for heart transplantation occurs in patients receiving a wide range of cumulative anthracycline doses. The time from chemotherapy to ACM varies. Outcomes after transplantation are acceptable, and cancer recurrence is rare. Reconsideration of the 5-year disease-free wait period is warranted.

Objective: To examine the stability and change in oppositional defiant disorder (ODD) with onset among preschool children in a pediatric sample., Method: A total of 510 children aged 2-5 years were enrolled initially in 1989-1990 (mean age 3.42 years); 280 participated in five waves of data collection over a period of 48 to 72 months (mean wave 5 age, 8.35 years). Test batteries varied by age, but they included the Child Behavior Checklist, developmental evaluation, Rochester Adaptive Behavior Inventory, and a play session (before age 7 years) and a structured interview (Diagnostic Interview for Children and Adolescents, parent and child versions) at ages 7+ years. Consensus diagnoses were assigned by using best-estimate procedures., Results: Wave 1 single-diagnosis ODD showed a significant relationship with both single-diagnosis ODD and single-diagnosis attention-deficit hyperactivity disorder (ADHD) at subsequent waves, but not with single-diagnosis anxiety or mood disorders. Single-diagnosis ODD at wave 1 was associated with later comorbidity of ODD/ADHD, ODD/anxiety, and ODD/mood disorders. Stability across waves 2 through 5 was moderate to high for comorbid ODD/anxiety and ODD/ADHD; low to moderate stability for single-diagnosis ODD and single-diagnosis mood disorder; and low for mood disorder, single-diagnosis ADHD, and single-diagnosis anxiety disorder., Conclusions: Preschool children with ODD are likely to continue to exhibit disorder, with increasing comorbidity with ADHD, anxiety, or mood disorders.

Context: Though prevention of adolescent tobacco use is a major public health goal, there is little information on the ability of pediatricians to identify adolescents experimenting with tobacco and regular tobacco users., Objectives: To pilot use of a short questionnaire and analysis of urinary cotinine level to identify adolescent smokers in a pediatric practice, and to determine characteristics of tobacco users., Setting: Suburban pediatric practice., Method: Consecutive high school students completed a short questionnaire and urine cotinine assessment. Three groups were defined: smokers (urine cotinine level >100 ng/mL), experimenters (smoked within the last year; urine continine level

Objectives: Newer combination antiretroviral therapies used to treat human immunodeficiency virus (HIV)-infected individuals have resulted in dramatic delays in HIV progression, with reduction in mortality and morbidity. However, adherence to highly active antiretroviral therapy (HAART) may be problematic, particularly in HIV-infected children. Reasons for nonadherence include refusal, drug tolerability, and adverse reactions. We assess: 1) the potential benefits of gastrostomy tube (GT) for the improvement of adherence to HAART in HIV-infected children, and 2) the factors that may result in improved viral suppression after GT placement., Methods: The medical records of 17 pediatric HIV-infected patients, in whom GT was used to improve HAART adherence, were retrospectively reviewed for clinical and laboratory parameters. Each record was reviewed for the period of 1 year before and after GT insertion. The main outcome parameters were virologic (plasma HIV RNA polymerase chain reaction quantification) and immunologic (CD4 cell counts). Documentation of adherence to medications in medical records was also assessed during the study. Parental questionnaires were used to determine GT satisfaction and medication administration times. The Wilcoxon rank sum test was used to assess change in viral load (VL) and CD4 cell percentages., Results: GT was well-tolerated with minor complications, such as local site tenderness, reported by 4 patients (23%). Before GT insertion, only 6 patients (35%) were documented as being adherent, compared with all patients after GT insertion. Ten patients (58%) had >/=2 log(10) VL decline after GT insertion (median: 3.2 log(10)), compared with 7 patients (42%) who had /=2 log(10) VL decline, therapy was changed at the time of or soon after GT insertion (median:.8 months; range: 0-6 months), compared with 7 patients with <2 log(10) VL decline who had therapy changed before GT insertion (median: 3.2 months; range: 1-8 months). Parental questionnaires reported significantly shorter medication administration times after GT insertion, with 70% of patients taking >5 minutes before GT, compared with 0% after GT. Questionnaires indicated satisfaction with GT, with perceived benefits being reduced medication administration time and improved behavior surrounding taking medications., Conclusions: GT is well-tolerated in pediatric HIV-infected patients and should be considered for selected patients to overcome difficulties with medication administration and to improve adherence. For maximal virologic response, combination therapy should be changed at the time of GT insertion.

Objectives: To describe (1) primary care providers' experiences identifying and reporting suspected child abuse to child protective services (CPS) and (2) variables affecting providers' reporting behavior., Design and Methods: Health care providers (76 physicians, 8 nurse practitioners, and 1 physician assistant) in a regional practice-based network completed written surveys that collected information about the demographic characteristics of each provider and practice; the provider's career experience with child abuse; and the provider's previous year's experience identifying and reporting suspected child abuse, including experience with CPS., Results: All providers (N = 85) in 17 participating practices completed the survey. In the preceding 1 year, 48 respondents (56%) indicated that they had treated a child they suspected was abused, for an estimated total of 152 abused children. Seven (8%) of 85 providers did not report a total of 7 children with suspected abuse (5% of all suspected cases). A majority of providers (63%; n = 29) believed that children who were reported had not benefited from CPS intervention, and 21 (49%) indicated that their experience with CPS made them less willing to report future cases of suspected abuse. Providers who had some formal education in child abuse after residency were 10 times more likely to report all abuse than were providers who had none., Conclusions: Primary care providers report most, but not all, cases of suspected child abuse that they identify. Past negative experience with CPS and perceived lack of benefit to the child were common reasons given by providers for not reporting. Education increases the probability that providers will report suspected abuse.

This study uses geostatistical techniques to model and estimate soil lead levels in an urban, residential neighborhood. Sixty-two composite soil samples (median 1773 ppm; range 175 to 7953 ppm) in a four-block area of brick and stone homes were obtained. The spatial continuity of soil lead levels was modeled with a semi-variogram, which was then used to estimate lead levels at unsampled locations, a process called kriging. Because soil lead levels were spatially correlated, it is likely that a "nonrandom" process generated the lead distribution found. This finding signifies the existence of lead sources which were tentatively identified on historical maps of the area and from past traffic volume patterns. The distribution of kriged estimates of soil lead levels provides an explanatory tool for exploring and identifying potential sources and may be useful for targeting urban soil abatement efforts.

Objective: To examine differences in the evaluation, management, and outcomes for patients seen in an on-site "fast track" (FT) vs the main ED., Methods: Over a three-month period, patients presenting to an urban pediatric ED were prospectively assessed. Patients included were: triaged as "nonurgent"; aged 2 months to 10 years; not chronically ill; and had fever, or complaint of vomiting, diarrhea, or decreased oral intake. Evening and weekend care was provided in the FT; at all other times these low-acuity patients were seen in the ED. Seven days after the visit, families were interviewed by telephone., Results: Four hundred seventy-nine and 557 patients were seen in the FT and ED, respectively. The patients in the two settings did not differ in age, clinical condition, race, or commercial insurance status. Patient mean test charges were $27 and $52 for the FT and ED, respectively (p < 0.01). Twenty-four percent of the FT patients vs 41% of the ED patients had tests performed (p < 0.01). Average length of stay was 28 minutes shorter in the FT (95% CI = 19 to 36, p < 0.01). Follow-up was completed for 480 of 755 families with telephones (64%). The FT and ED patients did not differ at follow-up: 90% vs 88% had improved conditions (p = 0.53), 18% vs 15% had received unscheduled follow-up care (p = 0.44), and 94% of the families in both groups were satisfied with the visit (p = 0.98)., Conclusions: Compared with those in the main ED, the study patients seen in the FT had fewer tests ordered and had briefer lengths of stay. These findings were not explained by differences in patient ages, vital signs, or demographic characteristics. No difference in final outcomes or satisfaction was detected among the families contacted for follow-up.

Objective: To examine the stability of the occurrence of psychiatric disorders in a nonpsychiatric sample of young children., Method: There were 510 children ages 2-5 years enrolled through pediatric practices, with 391 children participating in the second wave, and 344 in the third wave of data collection 42-48 months later. The assessment battery administered at each wave yielded best-estimate consensus DSM-III-R diagnoses and dimensional assessments of psychopathology., Results: The prevalence of disruptive disorders (DDs) decreased, while emotional disorders (EDs), other disorders, and comorbid DD increased. The DDs were associated with lower family cohesion, more maternal negative affect, stressful life events, and male gender. Comorbid DDs were associated with increasing age and family cohesion. Older children, lower family cohesion, and maternal negative affect were associated with EDs. Time trends for the dimensional assessment of psychopathology was similar to DSM-III-R disorders, but correlates differed., Conclusions: We discuss implications for service planning in pediatric primary care.

Background: Although an inability to speak English is recognized as an obstacle to health care in the United States, it is unclear how clinicians alter their diagnostic approach when confronted with a language barrier (LB)., Objective: To determine if a LB between families and their emergency department (ED) physician was associated with a difference in diagnostic testing and length of stay in the ED., Design: Prospective cohort study., Methods: This study prospectively assessed clinical status and care provided to patients who presented to a pediatric ED from September 1997 through December 1997. Patients included were 2 months to 10 years of age, not chronically ill, and had a presenting temperature >/=38.5 degrees C or complained of vomiting, diarrhea, or decreased oral intake. Examining physicians determined study eligibility and recorded the Yale Observation Score if the patient was <3 years old, and whether there was a LB between the physician and the family. Standard hospital charges were applied for each visit to any of the 22 commonly ordered tests. Comparisons of total charges were made among groups using Mann-Whitney U tests. Analysis of covariance was used to evaluate predictors of total charges and length of ED stay., Results: Data were obtained about 2467 patients. A total of 286 families (12%) did not speak English, resulting in a LB for the physician in 209 cases (8.5%). LB patients were much more likely to be Hispanic (88% vs 49%), and less likely to be commercially insured (19% vs 30%). These patients were slightly younger (mean 31 months vs 36 months), but had similar acuity, triage vital signs, and Yale Observation Score (when applicable). In cases in which a LB existed, mean test charges were significantly higher: $145 versus $104, and ED stays were significantly longer: 165 minutes versus 137 minutes. In an analysis of covariance model including race/ethnicity, insurance status, physician training level, attending physician, urgent care setting, triage category, age, and vital signs, the presence of a LB accounted for a $38 increase in charges for testing and a 20 minute longer ED stay., Conclusion: Despite controlling for multiple factors, the presence of a physician-family LB was associated with a higher rate of resource utilization for diagnostic studies and increased ED visit times. Additional study is recommended to explore the reasons for these differences and ways to provide care more efficiently to non-English-speaking patients.

Objective: We sought to determine whether information on hospital charges (prices) would affect test-ordering and quality of patient care in a pediatric emergency department (ED)., Design: Prospective, nonblind, controlled trial of price information., Setting: Urban, university-affiliated pediatric ED., Methods: We prospectively assessed patients 2 months to 10 years of age with a presenting temperature >/=38.5 degrees C or complaint of vomiting, diarrhea, or decreased oral intake. The assessments were done during three periods: September 1997 through December 1997 (control), January 1998 through March 1998 (intervention), and April 1998 (washout). In the control and washout periods, physicians noted tests ordered on a list attached to each chart. In the intervention period, physicians noted tests ordered on a similar list that included standard hospital charges for each test. Records of each visit were reviewed to determine clinical and demographic information as well as patient disposition. In the control and intervention periods, families of nonadmitted patients were interviewed by telephone 7 days after the visit., Results: When controlled for triage level, vital signs, and admission rates, in a multivariate model, charges for tests in the intervention period were 27% less than charges in the control period. The greatest decrease was seen among low-acuity, nonadmitted patients (43%). In telephone follow-up, patients in the intervention period were slightly more likely to have made an unscheduled follow-up visit to a health care provider (24.4% vs 17.8%), but did not differ on improved condition (86.7% vs 83.4%) or family satisfaction (93.8% vs 93.0%). Adjusted charges in the washout period were 15% lower than in the control period and 15% higher than in the intervention period., Conclusion: Providing price information was associated with a significant reduction in charges for tests ordered on pediatric ED patients with acute illness not requiring admission. This decrease was associated with a slightly higher rate of unscheduled follow-up, but no difference in subjective outcomes or family satisfaction.

Symptoms and laboratory evidence of adrenal suppression developed in 2 children with the human immunodeficiency virus after megestrol acetate (MA) therapy was discontinued; both required transient glucocorticoid replacement therapy. High-dose corticotropin stimulation testing performed on children with the human immunodeficiency virus treated or not treated with MA showed that baseline and post-corticotropin cortisol levels were extremely low in 7 of 10 treated patients and normal in 10 of 10 members of a control group (P <.01). MA may suppress adrenal function, and replacement glucocorticoids may prevent or relieve associated symptoms at times of severe stress or on discontinuation of MA therapy.

Objective: Beginning in 1995, Illinois law permitted targeted-as opposed to universal-blood lead screening in low-risk areas, which were defined by ZIP code characteristics. State guidelines recommended specific lead risk assessment questions to use when targeting screening. This study was designed to evaluate the sensitivity and specificity of Illinois lead risk assessment questions., Design: Parents bringing their 9- or 10- or 12-month and 24-month-old children for health supervision visits at 13 pediatric practices and parents of children (aged 6 through 25 months and who needed a blood lead test) receiving care at 5 local health departments completed a lead risk assessment questionnaire concerning their child. Children had venous or capillary blood lead testing. Venous confirmation results of children with a capillary level >/=10 micrograms/dL were used in analyses., Children: There were 460 children with both blood and questionnaire data recruited at the pediatric practices (58% of eligible) and 285 children (51% of eligible) recruited at local health departments. Of the 745 children studied, 738 provided a ZIP code that allowed their residence to be categorized as in a low-risk (n = 456) or high-risk (n = 282) area., Results: Sixteen children (3.5%) living in low-risk areas versus 34 children (12.1%) living in high-risk areas had a venous blood lead level (BLL) >/=10 micrograms/dL; 1.8% and 5.3%, respectively, had a venous BLL >/=15 micrograms/dL. For children living in low-risk areas, Illinois mandated risk assessment questions (concerning ever resided in home built before 1960, exposure to renovation, and exposure to adult with a job or hobby involving lead) had a combined sensitivity of.75 for levels >/=10 micrograms/dL and.88 for levels >/=15 micrograms/dL; specificity was.39 and.39, respectively. The sensitivity of these questions was similar among children from high-risk areas; specificity decreased to.27 and.28, for BLLs >/=10 micrograms/dL and >/=15 micrograms/dL, respectively. The combination of items requiring respondents to list house age (built before 1950 considered high risk) and indicate exposure to renovation had a sensitivity among children from low-risk areas of.62 for BLLs >/=10 micrograms/dL with specificity of.57; sensitivity and specificity among high-risk area children were.82 and.36, respectively. For this strategy, similar sensitivities and specificities for low and high-risk areas were found for BLLs >/=15 micrograms/dL., Conclusions: The Illinois lead risk assessment questions identified most children with an elevated BLL. Using these questions, the majority of Illinois children in low-risk areas will continue to need a blood lead test. This first example of a statewide screening strategy using ZIP code risk designation and risk assessment questions will need further refinement to limit numbers of children tested. In the interim, this strategy is a logical next step after universal screening.

Objective: To examine the correlates and predictors of stability and change in psychiatric disorder occurring among preschool children in a nonpsychiatric, primary care pediatric sample., Method: Five hundred ten children aged 2 through 5 years were enrolled; 344 participated in a third wave of data collection 42 through 48 months later. Consensus diagnoses were assigned using best-estimate procedures; variables of maternal psychopathology, family climate, and life stresses were the correlates/predictors studied., Results: For children who were cases initially, family cohesion predicted diagnostic stability. Among initial noncases, those remaining noncases experienced increased family cohesion; for those who later became cases, family cohesion declined. Negative life events declined when children were consistently noncases. Children who were initially noncases but were cases at the two subsequent waves had the highest levels of maternal negative affect. Predictors at wave 1 for wave 2 cases status included lower socioeconomic status, less family cohesiveness, and greater family inhibition/control. Wave 2 correlates of wave 2 status included older children and negative life events. Wave 2 predictors of wave 3 status included being older, while wave 3 correlates of wave 3 case status included older children and higher maternal negative affect., Conclusions: Family context contributes to the maintenance and onset of problems beginning in the preschool years.

Objectives: To examine the extent of parental knowledge about lead poisoning and its prevention and to determine characteristics associated with accurate lead knowledge., Setting: Twenty-three pediatric practices and 1 family practice in Chicago, Ill, and its suburbs., Methods: A 24-question test regarding lead poisoning and its prevention (Chicago Lead Knowledge Test) was developed based on lead specialists' review and parental test-retest reliability. One point was assigned for each correct response. It was self-administered by a sample of 2225 parents of 0- to 6-year-old children visiting study practices. A 1-way analysis of variance (ANOVA) was used to determine the association of demographic descriptors with test scores., Results: Respondents had a mean age of 33 years. Ninety percent were mothers, 49% were college graduates, and 80% were home owners. Fifteen percent lived in homes built before 1950, of which 36% were remodeled or renovated during the last 6 months. Respondents' youngest children were 80% white, 10% Hispanic, 5% African American, and 5% other. Ten percent received Medicaid and 86% had other medical insurance. Thirty-four percent recalled receipt of lead information from a health care provider, and 2.4% had had a child with a blood lead level of 0.48 micromol/L (10 microg/dL) or higher. The mean Chicago Lead Knowledge Test score was 12.2 (SD, 3.7). Questions related to lead exposure were more often answered correctly than those related to prevention and diet. In the ANOVA model, those who recalled receipt of lead information from a health care provider, college graduates, respondents aged 30 years or older, Hispanic respondents, and those living in homes built before 1950 had higher scores (all ANOVA P< or =.001)., Conclusions: Parents do not have much knowledge of ways to prevent childhood lead poisoning. Information from a health care provider can aid parental knowledge. The Chicago Lead Knowledge Test is a new self-administered tool to help evaluate lead education programs.

Objective: To examine the stability of psychiatric disorders with onset in preschool years., Method: Five hundred ten children aged 2 through 5 years enrolled initially, with 344 participating in a third wave of data collection 42 through 48 months later. The test batteries used for diagnoses varied by child's age, but they included the Child Behavior Checklist, developmental evaluation, Rochester Adaptive Behavior Inventory and a play session (under age 7 years), and a structured interview (Diagnostic Interview for Children and Adolescents, for parent and child) (ages 7 and older). Consensus DSM-III-R diagnoses were assigned using best-estimate procedures., Results: Intraclass correlations were 0.497 for emotional disorders, 0.718 for disruptive disorders, 0.457 for other diagnoses, and 0.544 for disruptive disorders comorbid with another disorder, indicating moderate stability for all groups of disorders. More than 50% of the children who were aged 2 through 3 years at wave 1 continued to have some psychiatric disorder at wave 2 or 3. Rates were higher for children aged 4 through 5 initially; approximately two thirds were cases subsequently. Odds ratios indicate that having an emotional or disruptive disorder is a strong risk factor for later diagnoses., Conclusions: While some preschool children in primary care "grow out of" their disorder, an equally large number do not; this finding supports the need for early detection and intervention.

Objective: To investigate the factors associated with mental health service use among young children., Method: Five hundred ten preschool children aged 2 through 5 years were enrolled through 68 primary care physicians, with 388 (76% of the original sample) participating in a second wave of data collection, 12 to 40 months later. Consensus DSM-III-R diagnoses were assigned using best-estimate procedures. The test battery included the Child Behavior Checklist, a developmental evaluation, the Rochester Adaptive Behavior Inventory, and a videotaped play session (preschool children) or structured interviews (older children). At wave 2, mothers completed a survey of mental health services their child had received., Results: In logistic regression models, older children, children with a wave 1 DSM-III-R diagnosis, children with more total behavior problems and family conflict, and children receiving a pediatric referral were more likely to receive mental health services. Among children with a DSM-III-R diagnosis, more mental health services were received by children who were older, white, more impaired, experiencing more family conflict, and referred by a pediatrician., Conclusions: Young children with more impairment and family conflict are more likely to enter into treatment. Services among young children of different races with diagnoses are not equally distributed. Pediatric referral is an important predictor of service use.

Objectives: To contrast practices of physicians' office laboratories in the years 1988 and 1996 and ascertain physicians' perception of the effect of the Clinical Laboratory Improvement Amendments of 1988 (CLIA)., Design: Mailed surveys to members of the Illinois chapter of the American Academy of Pediatrics in 1988 and 1996., Subjects: There were 525 and 980 respondents in 1988 and 1996, respectively; analyses included 282 and 374 surveys representing offices where direct patient care was provided in a nonhospital setting. A paired analysis was also conducted on 101 offices that responded to both surveys., Results: There was a decline from 1988 to 1996 in the percentage of offices doing in-office laboratory testing (93% to 84%, respectively; chi2 test; P<.01) and median number of types of tests (6 tests vs 4 tests; Mann-Whitney U test; P<.001). Decreases (chi2 test; P<.01) were seen in the proportion of offices offering throat culture for group A streptococci (63% to 33%), urinalysis (54% to 33%), urine culture (53% to 22%), rapid hemagglutination slide test for mononucleosis (42% to 17%), theophylline level (27% to 4%), and total cholesterol (22% to 13%). The proportion of offices offering urine dipstick, hematocrit or hemoglobin, complete blood cell count, and stool occult blood tests remained stable. For solo practitioner offices only, streptococcal antigen detection testing decreased (66% to 39%; chi2 test; P<.001). Findings in the paired analyses were similar. In 1996, more offices participated in a formal proficiency testing program (60% vs 11%; chi2 test; P<.001). The CLIA guidelines were deemed responsible for increased documentation (58%), discontinuing 1 or more tests (56%), increased frequency of quality control (50%), joining a proficiency program (40%), and increased cost to patients (32%)., Conclusions: These surveys provide large-scale data concerning change in office-based laboratories of physicians serving children during an 8-year period. Office laboratories reduced their menu of tests and enhanced documentation and quality control for the tests that were done. Data like these in multiple specialties over time contribute to a comprehensive picture of the effects of CLIA on office laboratory practices.

Objective: To examine the relationship between psychopathology and health care utilization beginning in the preschool (ages 2 to 5) years., Method: Five hundred ten preschool children were enrolled through 68 primary care physicians. The test battery used for diagnoses included the Child Behavior Checklist, a developmental evaluation, the Rochester Adaptive Behavior Inventory, and a videotaped play session. Consensus DSM-III-R diagnoses were assigned using best-estimate procedures. Frequency of primary care visits was established through 1-year retrospective record review; mothers estimated total visits and emergency department (ED) use., Results: Logistic regression models showed that a DSM-III-R diagnosis was related to increased ED use but not primary care or total visits. Greater functional impairment was associated with fewer primary care visits and more ED visits. Total, internalizing, and externalizing behavior problem scores were associated with increased primary care and total visits; ED visits were associated with increased total and internalizing problems. Child's health status consistently correlated with utilization., Conclusion: There is a consistent relationship between health care use and child psychopathology beginning in the preschool years.

Objective: To assess the management strategies and knowledge of board-certified pediatricians regarding group A beta-hemolytic streptococcal (GABHS) pharyngitis., Design: Survey of 1000 US pediatricians in 1991, chosen randomly from the membership of the American Academy of Pediatrics. The survey included questions related to 2 clinical scenarios, respondent demographics, and knowledge of streptococcal pharyngitis., Subjects: Pediatricians who treated patients with pharyngitis. Of the 690 surveys that were returned, 510 pediatricians treated patients with pharyngitis and were included in the data analysis., Data Analysis: Data were analyzed using Chi 2 statistics for categorical data and the Student t test for continuous variables., Results: Antigen detection tests (ADTs) were used by 64% of the pediatricians; 85% used throat cultures. Strategies for diagnosing streptococcal pharyngitis were throat culture alone (38%), consider positive ADTs definitive and use throat culture when ADTs are negative (42%), ADT alone (13%), ADT and throat culture for all patients with pharyngitis (5%), and no tests for GABHS performed (2%). Thirty-one percent usually or always treated with antibiotics before test results were available. Only 29% of these "early treaters" always discontinued antibiotics when tests did not confirm the presence of group A streptococci. The drug of choice for treatment was penicillin (73%); another 26% preferred a derivative of penicillin, particularly amoxicillin. Many pediatricians altered their management when a patient had recurrent streptococcal pharyngitis. Nearly half of the respondents would use a different antibiotic than they used for routine acute streptococcal pharyngitis. They most often changed to erythromycin (25%), cefadroxil (23%), or amoxicillin-clavulanate (20%). Follow-up throat culture was obtained by 51% of pediatricians after treatment of recurrent streptococcal pharyngitis. A patient with chronic carriage of GABHS and symptoms of pharyngitis would be treated with an antibiotic by 84%; most (62%) would use a penicillin. Other choices were cephalosporins (19%), erythromycin (12%), clindamycin (3%), or rifampin plus penicillin (3%). Tonsillectomy was recommended for symptomatic carriers by 31% of respondents. Carriers without symptoms were less likely to be treated with antibiotics (23%) or referred for tonsillectomy (21%)., Conclusions: Most surveyed board-certified pediatricians managed acute GABHS pharyngitis appropriately, but 15% to 20% used diagnostic or treatment strategies that are not recommended. There was lack of a consensus about the management of recurrent GABHS pharyngitis and chronic carriage of GABHS.

Background: Previous studies have assessed the attitudes of parents and children toward bicycle helmet ownership and use in various settings, but they have not addressed the role of parental rules in promoting bicycle helmet use by children., Objectives: To further explore the attitudes of parents and children at pediatric practices toward bicycle helmet ownership and use by children and to assess the role of parental rules in promoting bicycle helmet use by children., Design: One hundred sixty-nine 5- to 14-year-old children who owned bicycles and their parents were surveyed during well-child visits at 5 general pediatric practices in the Chicago, Ill, area. One hundred twenty-nine families were represented. Of the children, 60% were aged 5 to 9 years, and 50% were girls., Results: Forty-eight children (28%) reported helmet ownership. Of the helmet owners, 21 (45%) reported helmet use; thus, the overall percentage of helmet use was 12%. Helmet ownership by children was significantly (P < .05) related to parental characteristics: educational level, race, perceived effectiveness of bicycle helmets, seat belt use, and parental helmet ownership. The most common reasons parents gave for lack of helmet ownership by children were "never thought about purchasing" a helmet (35%), "never got around to purchasing" a helmet (29%), "child wouldn't wear it anyway" (26%), and the bicycle helmet was "too expensive" (16%). Only 33% of the parents reported hearing about helmets from their children's pediatrician, but 40% of these parents regarded pediatricians as their most important information source. Of the children who did not own helmets, 64% said they would wear a bicycle helmet if they had one, a more frequent comment for 5- to 9-year-old children than 10- to 14-year-old children (76% vs 49%, P < .01). The most common reasons for not wearing a helmet among owners were as follows: forgot or lost it and not needed. The most common reasons for not wearing a helmet among nonowners were as follows: uncomfortable and appearance or perception of others. Children who owned helmets and whose parents had a strict rule about wearing helmets were more likely to always wear their helmets than helmet owners whose parents had a partial rule or no rule (88% vs 19%, P < .001)., Conclusions: Parental rules are associated with bicycle helmet use by children. Pediatricians may increase helmet use rates by promoting strict parental helmet rules as part of their anticipatory guidance regarding bicycle safety. More research about the effectiveness of this strategy is needed.
