Item Breakage in the SNRPN locus in a balanced 46,XY,t(15;19) Prader-Willi syndrome patient(Oxford Academic, 1996-04) Sun, Yongming; Nicholls, Robert D.; Butler, Merlin G.; Saitoh, Shinji; Hainline, Bryan E.; Palmer, Catherine G.; Medical and Molecular Genetics, School of MedicineA patient with Prader-Willi syndrome (PWS) was found to carry a de novo balanced reciprocal translocation, t(15;19)(q12;q13.41), which disrupted the small nuclear ribonucleoprotein N (SNRPN) locus. The translocation chromosome 15 was found to be paternal in origin. Uniparental disomy and abnormal DNA methylation were ruled out. The translocation breakpoint was found to have occurred between exon 0 (second exon) and 1 (third exon) of the SNRPN locus outside of the SmN open reading frame (ORF), which is intact. The transcriptional activities of ZNF127, IPW, PAR-1, and PAR-5 were detected with RT-PCR from fibroblasts of the patient, suggesting that these genes may not play a significant role in the PWS phenotype in this patient. Transcription from the first two exons and last seven exons of the SNRPN gene was also detected with RT-PCR; however, the complete mRNA (10 exons) was not detected. Thus, the PWS phenotype in the patient is likely to be the result of disruption of the SNRPN locus.Item Clinical Comparison of Retinopathy-Positive and Retinopathy-Negative Cerebral Malaria(American Society of Tropical Medicine and Hygiene, 2017-05) Villaverde, Chandler; Namazzi, Ruth; Shabani, Estela; Opoka, Robert O.; John, Chandy C.; Pediatrics, School of MedicineAbstractCerebral malaria (CM) is a severe and often lethal complication of falciparum malaria. A classic malaria retinopathy is seen in some (retinopathy-positive [RP]) children but not others (retinopathy-negative [RN]), and is associated with increased parasite sequestration. It is unclear whether RN CM is a severe nonmalarial illness with incidental parasitemia or a less severe form of the same malarial illness as RP CM. Understanding the clinical differences between RP and RN CM may help shed light on the pathophysiology of malarial retinopathy. We compared clinical history, physical examination, laboratory findings, and outcomes of RP (N = 167) and RN (N = 87) children admitted to Mulago Hospital, Kampala, Uganda. Compared with RN children, RP children presented with a longer history of illness, as well as physical examination and laboratory findings indicative of more severe disease and organ damage. The hospital course of RP children was complicated by longer coma duration and a greater transfusion burden than RN children. Mortality did not differ significantly between RP and RN children (14.4% versus 8.0%, P = 0.14). Further, severity of retinal hemorrhage correlated with the majority of variables that differed between RP and RN children. The data suggest that RP and RN CM may reflect the spectrum of illness in CM, and that RN CM could be an earlier, less severe form of disease.Item Clinical features of young children referred for impairing temper outbursts(Mary Ann Liebert, 2013-11) Roy, Amy K.; Klein, Rachel G.; Angelosante, Aleta; Bar-Haim, Yair; Leibenluft, Ellen; Hulvershorn, Leslie; Dixon, Erica; Dodds, Alice; Spindel, Carrie; Psychiatry, School of MedicineOBJECTIVE: In light of the current controversy about whether severe temper outbursts are diagnostic of mania in young children, we conducted a study to characterize such children, focusing on mania and other mood disorders, emotion regulation, and parental psychiatric history. METHODS: Study participants included 51 5-9-year-old children with frequent, impairing outbursts (probands) and 24 non-referred controls without outbursts. Parents completed a lifetime clinical interview about their child, and rated their child's current mood and behavior. Teachers completed a behavior rating scale. To assess emotion regulation, children were administered the Balloons Game, which assesses emotion expressivity in response to frustration, under demands of high and low regulation. Parental lifetime diagnoses were ascertained in blind clinical interviews. RESULTS: No child had bipolar disorder, bipolar disorder not otherwise specified (NOS), or major depression (MDD). The most prevalent disorder was oppositional defiant disorder (88.2%), followed by attention-deficit/hyperactivity disorder (74.5%), anxiety disorders (49.0%), and non-MDD depressive disorders (33.3%). Eleven probands (21.6%) met criteria for severe mood dysregulation. During the Balloons Game, when there were no demands for self-regulation, children with severe outbursts showed reduced positive expressivity, and also showed significant deficits in controlling negative facial expressions when asked to do so. Anxiety disorders were the only diagnoses significantly elevated in probands' mothers. CONCLUSIONS: Overall, young children with severe temper outbursts do not present with bipolar disorder. Rather, disruptive behavior disorders with anxiety and depressive mood are common. In children with severe outbursts, deficits in regulating emotional facial expressions may reflect deficits controlling negative affect. This work represents a first step towards elucidating mechanisms underlying severe outbursts in young children.Item Conscious Sedation of the pediatric dental patient: a comparison of meperidine versus butorphanol(2001) Guthrie, Andrew C. (Andrew Cleveland), 1969-; Sanders, Brian J.; Majcher, Thomas; Tomlin, Angela; Weddell, James A. (James Arthur), 1949-; Avery, David R.Treating pediatric dental patients four years old and younger can be difficult at times due to patient behavior. Conscious sedation has been employed as a means to control pediatric dental patients for several years. Butorphanol tartrate has been used safely for pain control in pediatric patients for several years, but has never been used for sedating pediatric dental patients. The purpose of this study is to compare the behavioral and physiologic effects of conscious sedation on pediatric dental patients using intramuscular meperidine and an equipotent dosage of intramuscular butorphanol. Forty conscious sedations of ASA I pediatric dental patients between the ages of 13 and 60 months were accomplished using either 2.0 mg/kg of intramuscular meperidine or 0.03 mg/kg of intramuscular butorphanol. Each sedation was videotaped and three viewers viewed the videotapes rating them with a computer program (ACS) involving a four-code behavior rating scale. The tlrree viewers rated patient behavior for each sedation also with a form with global rating, categorical, and dichotomous scales. Physiologic signs of oxygen saturation, blood pressure, heart rate, and respiration rate were monitored at baseline and every 5 minutes during treatment. The operator also rated the sedation patient behavior with a form that had pre-treatment Frankl, post-treatment Frankl, global rating categorical, dichotomous, and sedation success rating scales. The two groups demographic data, physiologic data, ACS data, the three viewer's behavior rating form, and the operator's behavior rating form were analyzed for any statistically significant differences between the groups. The statistical analysis of the demographic data revealed a statistically significant trend in the butorphanol group toward extractions. The meperidine group had a statistically significant higher mean oxygen saturation during treatment (99.63 percent) than the butorphanol group (99.20 percent). The butorphanol group spent significantly more time in the annoyed ACS behavior rating code and showed a trend toward less time spent in the quiet ACS behavior rating code. There were no statistically significant differences in the three viewers ratings of global rating, categorical, and dichotomous scales. The operators' ratings showed the meperidine group had a statistically significant better global rating than the butorphanol group. Overall butorphanol appears to be equal clinically to meperidine in physiologic effects and patient behavior effects. No adverse effects occurred with either medication. Butorphanol may be offered as an alternative sedative agent to other narcotic sedative agents with more side effects.Item Correlation between caries prevalence and socioeconomic status in children ages 6 to 36 months(2000) Ching, Brent Bing Yee; Weddell, James A. (James Arthur), 1949-; Sanders, Brian J.; Tomlin, Angela; Dean, Jeffrey A.; Klein, Arthur Irving, 1922-2004The purpose of this study was to evaluate the status of a sample of children ages 6 to 36 months with regard to prevalence of tooth decay in a community with an optimum fluoridated water supply. It was determined whether a relation existed between these data and the socioeconomic level of the family. One hundred and fifty children ages 6 to 36 months born and reared in Marion County, Indiana were examined with a dental mirror, explorer and a portable light. Parents/legal guardians of these children were given a questionnaire to obtain family history. Caries prevalence for children ages 6 to 12, 13 to 18, 19 to 24, 25 to 30, and 31 to 36 months were 4%, 0%, 22%, 23%, and 26%, respectively. Age, mother's educational attainment, and Medicaid experience remained significant predictors of caries experience: the odds of caries were 1.1 times for each monthly increase in age. Gender, father's educational attainment, family household income, and single parent status remained marginally significant predictors of caries experience. Results for similar correlation studies between caries prevalence and socioeconomic status for children ages 6 to 36 months are inconsistent. Further research is needed for children ages 6 to 36 months. Caries experience begins before age one. Patients, parents, and health care professionals need to be aware that the caries process begins at an early age, and prevention should begin as early as 6 months of age.Item Dysglycemia and Index60 as Prediagnostic End Points for Type 1 Diabetes Prevention Trials(American Diabetes Association, 2017-11) Nathan, Brandon M.; Boulware, David; Geyer, Susan; Atkinson, Mark A.; Colman, Peter; Goland, Robin; Russell, William; Wentworth, John M.; Wilson, Darrell M.; Evans-Molina, Carmella; Wherrett, Diane; Skyler, Jay S.; Moran, Antoinette; Sosenko, Jay M.; Type 1 Diabetes TrialNet and Diabetes Prevention Trial–Type 1 Study Groups; Medicine, School of MedicineOBJECTIVE: We assessed dysglycemia and a T1D Diagnostic Index60 (Index60) ≥1.00 (on the basis of fasting C-peptide, 60-min glucose, and 60-min C-peptide levels) as prediagnostic end points for type 1 diabetes among Type 1 Diabetes TrialNet Pathway to Prevention Study participants. RESEARCH DESIGN AND METHODS: Two cohorts were analyzed: 1) baseline normoglycemic oral glucose tolerance tests (OGTTs) with an incident dysglycemic OGTT and 2) baseline Index60 <1.00 OGTTs with an incident Index60 ≥1.00 OGTT. Incident dysglycemic OGTTs were divided into those with (DYS/IND+) and without (DYS/IND-) concomitant Index60 ≥1.00. Incident Index60 ≥1.00 OGTTs were divided into those with (IND/DYS+) and without (IND/DYS-) concomitant dysglycemia. RESULTS: The cumulative incidence for type 1 diabetes was greater after IND/DYS- than after DYS/IND- (P < 0.01). Within the normoglycemic cohort, the cumulative incidence of type 1 diabetes was higher after DYS/IND+ than after DYS/IND- (P < 0.001), whereas within the Index60 <1.00 cohort, the cumulative incidence after IND/DYS+ and after IND/DYS- did not differ significantly. Among nonprogressors, type 1 diabetes risk at the last OGTT was greater for IND/DYS- than for DYS/IND- (P < 0.001). Hazard ratios (HRs) of DYS/IND- with age and 30- to 0-min C-peptide were positive (P < 0.001 for both), whereas HRs of type 1 diabetes with these variables were inverse (P < 0.001 for both). In contrast, HRs of IND/DYS- and type 1 diabetes with age and 30- to 0-min C-peptide were consistent (all inverse [P < 0.01 for all]). CONCLUSIONS: The findings suggest that incident dysglycemia without Index60 ≥1.00 is a suboptimal prediagnostic end point for type 1 diabetes. Measures that include both glucose and C-peptide levels, such as Index60 ≥1.00, appear better suited as prediagnostic end points.Item An empirical study of multidimensional fidelity of COMPASS consultation(American Psychological Association, 2018-06) Wong, Venus; Ruble, Lisa A.; McGrew, John H.; Yu, Yue; Psychology, School of ScienceConsultation is essential to the daily practice of school psychologists (National Association of School Psychologist, 2010). Successful consultation requires fidelity at both the consultant (implementation) and consultee (intervention) levels. We applied a multidimensional, multilevel conception of fidelity (Dunst, Trivette, & Raab, 2013) to a consultative intervention called the Collaborative Model for Promoting Competence and Success (COMPASS) for students with autism. The study provided 3 main findings. First, multidimensional, multilevel fidelity is a stable construct and increases over time with consultation support. Second, mediation analyses revealed that implementation-level fidelity components had distant, indirect effects on student Individualized Education Program (IEP) outcomes. Third, 3 fidelity components correlated with IEP outcomes: teacher coaching responsiveness at the implementation level, and teacher quality of delivery and student responsiveness at the intervention levels. Implications and future directions are discussed.

Kirk; Kletter, Gad B.; Lewis, Katherine; Chitra, Surya; Terleckyj, Oksana; Eugster, Erica A.; Department of Medicine, IU School of MedicineCONTEXT AND OBJECTIVE: The histrelin implant has proven to be an effective method of delivering GnRH analog (GnRHa) therapy to children with central precocious puberty (CPP), yet there are limited data available regarding hormonal suppression and auxological changes during an extended course of therapy. DESIGN: This was a phase 3, prospective, open-label study. SETTING AND PARTICIPANTS: Thirty-six children with CPP who participated in a phase 3, open-label study and required further GnRHa therapy were eligible to continue treatment receiving a new implant upon removal of the prior 12-month histrelin implant during a long-term extension phase. OUTCOME MEASURES: Hormone levels and auxologic parameters were measured periodically for up to 6 years of treatment and up to 1 year of posttreatment follow-up. RESULTS: Hormonal suppression was maintained throughout the study in patients who had prior GnRHa therapy (n = 16) and in treatment-naive patients (n = 20). Bone age to chronological age ratio decreased from 1.417 (n = 20) at baseline to 1.18 (n = 8) at 48 months in treatment-naive children (P < .01). Predicted adult height in girls increased from 151.9 cm at baseline to 166.5 cm at month 60 (n = 6; P < .05), with a 10.7-cm height gain observed among treatment-naive children (n = 5). No adverse effect on growth or recovery of the hypothalamic-pituitary-gonadal axis was observed with hormonal suppression. The histrelin implant was generally well tolerated during long-term therapy. CONCLUSIONS: Long-term histrelin implant therapy provided sustained gonadotropin suppression safely and effectively and improved predicted adult height in children with CPP.Item Mutations in SLC34A3/NPT2c are associated with kidney stones and nephrocalcinosis(American Society of Nephrology, 2014-10) Dasgupta, Debayan; Wee, Mark J.; Reyes, Monica; Li, Yuwen; Simm, Peter J.; Sharma, Amita; Schlingmann, Karl-Peter; Janer, Marco; Biggin, Andrew; Lazier, Joanna; Gessner, Michaela; Chrysis, Dionisios; Tuchman, Shamir; Baluarte, H. Jorge; Levine, Michael A.; Tiosano, Dov; Insogna, Karl; Hanley, David A.; Carpenter, Thomas O.; Ichikawa, Shoji; Hoppe, Bernd; Konrad, Martin; Sävendahl, Lars; Munns, Craig F.; Lee, Hang; Jüppner, Harald; Bergwitz, Clemens; Department of Medicine, IU School of MedicineCompound heterozygous and homozygous (comp/hom) mutations in solute carrier family 34, member 3 (SLC34A3), the gene encoding the sodium (Na(+))-dependent phosphate cotransporter 2c (NPT2c), cause hereditary hypophosphatemic rickets with hypercalciuria (HHRH), a disorder characterized by renal phosphate wasting resulting in hypophosphatemia, correspondingly elevated 1,25(OH)2 vitamin D levels, hypercalciuria, and rickets/osteomalacia. Similar, albeit less severe, biochemical changes are observed in heterozygous (het) carriers and indistinguishable from those changes encountered in idiopathic hypercalciuria (IH). Here, we report a review of clinical and laboratory records of 133 individuals from 27 kindreds, including 5 previously unreported HHRH kindreds and two cases with IH, in which known and novel SLC34A3 mutations (c.1357delTTC [p.F453del]; c.G1369A [p.G457S]; c.367delC) were identified. Individuals with mutations affecting both SLC34A3 alleles had a significantly increased risk of kidney stone formation or medullary nephrocalcinosis, namely 46% compared with 6% observed in healthy family members carrying only the wild-type SLC34A3 allele (P=0.005) or 5.64% in the general population (P<0.001). Renal calcifications were also more frequent in het carriers (16%; P=0.003 compared with the general population) and were more likely to occur in comp/hom and het individuals with decreased serum phosphate (odds ratio [OR], 0.75, 95% confidence interval [95% CI], 0.59 to 0.96; P=0.02), decreased tubular reabsorption of phosphate (OR, 0.41; 95% CI, 0.23 to 0.72; P=0.002), and increased serum 1,25(OH)2 vitamin D (OR, 1.22; 95% CI, 1.05 to 1.41; P=0.008). Additional studies are needed to determine whether these biochemical parameters are independent of genotype and can guide therapy to prevent nephrocalcinosis, nephrolithiasis, and potentially, CKD.Item Prevalence and correlates of pain and pain treatment in a western Kenya referral hospital(Mary Ann Liebert, Inc., 2013-10) Huang, Kristin T. L.; Owino, Claudio; Gramelspacher, Gregory P.; Monahan, Patrick O.; Tabbey, Rebeka; Hagembe, Mildred; Strother, Robert M.; Njuguna, Festus; Vreeman, Rachel C.; Department of Medicine, IU School of MedicineBACKGROUND: Pain is often inadequately evaluated and treated in sub-Saharan Africa (SSA). OBJECTIVE: We sought to assess pain levels and pain treatment in 400 hospitalized patients at a national referral hospital in western Kenya, and to identify factors associated with pain and pain treatment. DESIGN: Using face-validated Kiswahili versions of two single-item pain assessment tools, the Numerical Rating Scale (NRS) and the Faces Pain Scale-Revised (FPS-R), we determined patients' pain levels. Additional data collected included patient demographics, prescribed analgesics, and administered analgesics. We calculated mean pain ratings and pain management index (PMI) scores. RESULTS: Averaged between the NRS and FPS-R, 80.5% of patients endorsed a nonzero level of pain and 30% of patients reported moderate to severe pain. Older patients, patients with HIV, and cancer patients had higher pain ratings. Sixty-six percent of patients had been prescribed analgesics at some point during their hospitalization, the majority of which were nonopioids. A majority of patients (66%) had undertreated pain (negative scores on the PMI). CONCLUSION: This study shows that hospitalized patients in Kenya are experiencing pain and that this pain is often undertreated.
