Krell K, Haugen K, Torres A, Santoro SL. Description of Daily Living Skills and Independence: A Cohort from a Multidisciplinary Down Syndrome Clinic. Brain Sci 2021; 11:brainsci11081012. [PMID: 34439631 PMCID: PMC8391843 DOI: 10.3390/brainsci11081012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 07/26/2021] [Accepted: 07/27/2021] [Indexed: 01/29/2023] Open
Abstract
Levels of independence vary in individuals with Down syndrome (DS). We began this study to describe the current life skills in our clinic population of children and adults with DS. We collected and reviewed demographics, living situation, and life skills from an electronic intake form used in clinic procedures. Descriptive statistics for this cohort study included mean, standard deviation, and frequencies. From 2014–2020, 350 pediatric and 196 adult patients (range 0–62 years) with a first visit to the Massachusetts General Hospital Down Syndrome Program are described. Pediatric patients were most often enrolled in school, and in an inclusion setting. Adult patients were most often participating in a day program, living with family, and wanted to continue living with family in the future. Most (87%) of adults with DS communicated verbally, though fewer could use written communication (17%). Life skills of greatest importance to adolescents and adults with DS included: learning about healthy foods (35%), preparing meals (34%), providing personal information when needed (35%), and describing symptoms to a doctor (35%). Life skills for patients with DS are varied; those associated with a medical appointment, such as sharing symptoms with the doctor, could improve for greater independence.

Abstract
Down syndrome is one of the most common chromosomal abnormalities. In 2014, in conjunction with the passing of House Bill 552, the Ohio Department of Health released a Down syndrome fact sheet to be given to parents at time of diagnosis to answer basic questions regarding the diagnosis. Our survey helps us to understand parental experience in receiving a new Down syndrome diagnosis including information provided. An electronic survey was created and distributed to members of established Down syndrome parent groups in Ohio. Questions assessed the parental experience at the time of receiving a Down syndrome. We also looked at parent perceptions after the implementation of a Down syndrome fact sheet. Responses were collected regarding experience at the time of diagnosis and broadly categorized into a trichotomy of positive experience (>5), neutral experience (=5), and negative experience (<5). Parents report an overall negative experience when receiving a new diagnosis of Down syndrome (mean of 4 on scale of 0-10), which did not increase after 2014 (p >0.05). Eighty-five percent of parents with children born in 2014 or after report that they did not receive the Ohio Department of Health Down syndrome fact sheet. Legislation regarding a diagnosis of Down syndrome exists in 20 states with significant variability, readability of those fact sheets. Legislation requiring accurate information be given to families was not always followed, and printed literature alone did not correlate with improved parent experience; additional efforts are necessary to ensure that the experience receiving a diagnosis of Down syndrome is not a negative one.

Blake JM, Estrada Gomez D, Skotko BG, Torres A, Santoro SL. Pneumonia and respiratory infection in Down syndrome: A 10-year cohort analysis of inpatient and outpatient encounters across the lifespan. Am J Med Genet A 2021; 185:2878-2887.

Abstract
Respiratory illnesses are a significant contributor of morbidity and mortality among persons with Down syndrome (DS). Reviews have described respiratory illnesses of DS in childhood, but few have looked across the lifespan. Retrospective chart review of patients in our DS program with clinical encounters for respiratory illnesses from 2011 to 2020 was completed. Eighteen percent of clinical encounters were due to respiratory illnesses. Of these, 120 were seen in the emergency department, 88 were admitted, and 21 were seen in urgent care. Common comorbidities included congenital heart disease, asthma, and dysphagia. Admission was common for children under the age of 5 years and adults over the age of 45 years. Admitted patients were more likely to have history of pneumonia and chronic lung disease. Of admitted patients, 77% required supplemental oxygen and 46% required intensive care unit admission. Our findings highlight that respiratory illnesses are a common cause of healthcare utilization among patients with DS, particularly early in childhood and later in life. Patients were seen predominately in outpatient settings; when an inpatient setting was needed, they frequently required higher levels of care. With our findings, clinicians can stratify patients most at risk for respiratory infections and provide targeted monitoring.

Abstract
PURPOSE People with Down syndrome (DS) have a unique medical profile which may impact views of health. We aimed to explore the use of global health measures in DS. METHODS Prospective survey in the Mass General Hospital Down Syndrome Program (MGH DSP) from December 2018 to July 2019 with Patient Reported Outcomes Measurement Information System (PROMIS)® instruments of global health. Analyses included use of scoring manuals, descriptive statistics and dependent samples t test. RESULTS Seventeen adolescents, 48 adults with DS and 88 caregivers returned surveys; 137 were complete. Incomplete responses and notes showed limitations of the instruments in this population. Global health T-scores did not differ from the available comparative standardized scores to these measures from PROMIS® reference population (p > 0.05). CONCLUSIONS In the MGH DSP, pilot global health instruments were completed by some adults with DS and caregivers, with some limitations and scores similar to the PROMIS® reference population.

Abstract
Specialty centers improve care for patients with Down syndrome. The cohort of adults with Down syndrome is increasing, but the capacity for specialty centers to meet their medical care needs is unknown. Electronic survey of staff of specialty clinics for adults with Down syndrome was conducted. Review of online clinic listings, and calculation of the number of adults with Down syndrome were performed. Analysis identified the percent of adults with Down syndrome who could have their medical care needs met in a current specialty clinic. Fourteen specialty clinics report providing care for 4038 adults with Down syndrome. Respondents reported gaps in care including: limitations of existing clinics, need for additional clinics, and knowledgeable health professionals in Down syndrome. Survey-respondent clinic capacity would meet needs of 3% of adults with Down syndrome. Twenty-five clinics for adults with Down syndrome were listed online with capacity to care for 6517 adults with Down syndrome meeting the needs of 5% of the population. Additional clinic capacity is needed to meet the needs of adults with Down syndrome. Survey of existing clinics provides guidance to create additional clinics, including: must-have team members, current sources of clinic financial support, and gaps in current clinical care.

Abstract
Abstract
Background
Congenital heart disease (CHD) is a well-known co-occurring condition in Down syndrome (DS). We aimed to review the literature to evaluate the current evidence to address key questions.
Methods
A series of key questions were formulated a priori to inform the search strategy and review process. These addressed the topics of prevalence, type of CHD, severity, and screening. Using the National Library of Medicine database, PubMed, detailed literature searches were performed. The quality of available evidence was then evaluated, the existing literature was summarized, and knowledge gaps were identified.
Results
Fifty-six relevant original articles were identified which addressed at least one key question. Study details, including: research design, internal validity, external validity, and relevant results are presented. The total prevalence of CHD reported in DS ranged from 20 to 57.9%. In later decades, the prevalence remained constant at 40—55%. The types and classification of CHD varied considerably between studies. Some studies indicate a trend towards a milder phenotype, but this was not consistent. Over time, some studies observed an improved prognosis for CHD in DS. Studies investigating screening for CHD by physical examination, chest X-ray, and electrocardiogram report sensitivities of 71–95%.
Conclusion
To further improve knowledge on CHD in DS, we suggest that future studies cover a wide range of nations and regions, with a longitudinal design, and account for potential confounding factors.

Abstract
The COVID-19 pandemic necessitated a rapid transition from in-person office visits to virtual visits in the Down syndrome specialty program at Massachusetts General Hospital (MGH DSP). We describe the clinic transition to virtual visits in April 2020 and reflect on our six-month experience in virtual visits. Clinic metrics were tracked. Electronic survey responses were collected from caregivers attending virtual visits. Input from the MGH DSP team was collected. From April to September 2020, we maintained patient volume (45 visits per month) and overall satisfaction score (6.7 out of 7) following a sudden, unanticipated transition to virtual visits. Survey of 17 caregivers attending virtual visits found that most were equipped with technology, had access to a private location, and most were able to access visit without any limitations. Caregivers appreciated the convenience of virtual visits but sometimes missed the personal connection of an in-person visit. Overall, though, virtual visits were frequently viewed as no different than office visits. Team members identified benefits and challenges of virtual visits, as well as lessons learned from this transition. We were able to maintain multidisciplinary, specialty care with optimal caregiver feedback and sustained number of patient visits.

Abstract
Pneumonia and respiratory infections impact infants and children with Down syndrome; pneumonia is a leading cause of mortality in adults with Down syndrome. We aimed to review the literature to evaluate gaps and address key questions. A series of key questions were formulated a priori to inform the search strategy and review process; addressed prevalence, severity, etiology, risk factors, preventive methods, screening, and financial costs, potential benefits or harms of screening. Using the National Library of Medicine database, PubMed, detailed literature searches on pneumonia and respiratory infections in Down syndrome were performed. Previously identified review articles were also assessed. The quality of available evidence was then evaluated and knowledge gaps were identified. Forty-two relevant original articles were identified which addressed at least one key question. Study details including research design, internal validity, external validity, and relevant results are presented. Pneumonia and respiratory infections are more prevalent and more severe in individuals with Down syndrome compared to healthy controls through literature review, yet there are gaps in the literature regarding the etiology of pneumonia, the infectious organism, risk factors for infection, and to guide options for prevention and screening. There is urgent need for additional research studies in Down syndrome, especially in the time of the current COVID-19 pandemic.

Abstract
PURPOSE We sought to determine if a novel online health tool, called Down Syndrome Clinic to You (DSC2U), could improve adherence to national Down syndrome (DS) guidelines. We also sought to determine if primary care providers (PCPs) and caregivers are satisfied with this personalized online health tool. METHODS In a national, randomized controlled trial of 230 caregivers who had children or dependents with DS without access to a DS specialist, 117 were randomized to receive DSC2U and 113 to receive usual care. The primary outcome was adherence to five health evaluations indicated by national guidelines for DS. DSC2U is completed electronically, in all mobile settings, by caregivers at home. The outputs-personalized checklists-are used during annual wellness visits with the patient's PCP. RESULTS A total of 213 participants completed a 7-month follow-up evaluation. In the intention-to-treat analysis, the intervention group had a 1.6-fold increase in the number of indicated evaluations that were recommended by the primary care provider or completed compared with controls. Both caregivers and PCPs reported high levels of satisfaction with DSC2U. CONCLUSIONS DSC2U improved adherence to the national DS health-care guidelines with a novel modality that was highly valued by both caregivers and PCPs.

Abstract
OBJECTIVE To evaluate disease-specific guideline adherence among children with 22q11.2 deletion syndrome receiving multidisciplinary team care through a 22q specialty clinic compared to children not receiving team care. DESIGN Retrospective chart review; quality improvement project. SETTING Tertiary care pediatric hospital. PATIENTS One hundred eighty-nine patients with 22q11.2 deletion syndrome were categorized into those receiving team care and those not receiving team care. Guideline adherence was compared between the 2 groups. MAIN OUTCOME MEASURE(S) Percent adherence across 8 disease-specific guidelines. RESULTS A Welch t test revealed mean adherence among patients receiving team care was significantly higher (83% vs 42%, P < .001) compared those not receiving team care. Among team patients with a single 22q Center visit, a paired samples t test showed that mean adherence increased from 63% before the clinic encounter to 86% six months after the encounter (P < .001). Some guidelines were more likely to be associated with provider nonadherence, whereas others were more likely to be associated with patient nonadherence. CONCLUSIONS Multidisciplinary team care is associated with significantly higher guideline adherence in children with 22q11DS. Additional research is needed to investigate the effect of team care on long-term health outcomes in children with 22q11DS.

Abstract
The objectives of this study were to determine if any specific clinical signs, symptoms, or comorbidities could reliably predict underlying feeding difficulty and need for further evaluation (i.e., video swallow study, VSS) in infants with Down syndrome, to establish the prevalence of gastrostomy tube placement (G-tube), and to determine if any clinical signs, symptoms, or comorbidities correlated with a higher risk for needing placement of a G-tube. An electronic medical record retrospective chart review of 73 children with Down syndrome born between January 2013 and March 2017 and seen in Nationwide Children's Hospital's multidisciplinary Down Syndrome Clinic included demographic information, medical history, and results of studies and specialist evaluations. Descriptive statistics were utilized to summarize the data. Comparisons were performed to identify factors which differed between feeding difficulty vs. no feeding difficulty and G-tube placement vs. no G-tube placement. "Feeding difficulty" was the only feeding term established by the AAP guidelines which was consistently noted in charts of children with feeding abnormalities. Infants with feeding difficulty had increased use of medical services and more abnormalities on specialist evaluations and studies. Congenital heart disease, cardiothoracic surgery, obstructive sleep apnea, and hypothyroidism did not differ significantly between the groups assessed. Our cohort had a prevalence of 13.7% for requiring G-tube placement in their first year of life.Conclusion: The currently established clinical tools for determining which patients may benefit from radiographic evaluation lack sufficient sensitivity to detect all individuals with feeding difficulty. Due to the high prevalence of abnormal VSS results and high rate of G-tube placement, universal radiographic screening for individuals with Down syndrome could be considered, even in the absence of obvious clinical signs or symptoms. However, determining how to balance this with cost, availability, and radiation exposure may be difficult.What is Known: • Feeding difficulty in children with Down syndrome can lead to significantly increased morbidity, such as poor weight gain, failure to thrive, aspiration, persistent respiratory symptoms, andrecurrent pneumonia. • The AAP has established a clinical tool regarding which objective signs and symptoms should lead to a radiographic swallowing assessment within their Health Supervision for Children with Down Syndrome Clinical Report.What is New: • A comprehensive assessment of clinical signs, symptoms, and common comorbidities in infants with Down syndrome has not previously been correlated with presence of feeding difficulty nor necessity for gastrostomy tube placement, including whether or not the terms used in the AAP guidelines encompass the sensitivity required to detect all infants with feeding difficulty. • The prevalence of gastrostomy tube placement in children with Down syndrome has not previously been established.

Abstract
Down syndrome disintegrative disorder (DSDD), a developmental regression in children with Down syndrome (DS), is a clinical entity that is characterized by a loss of previously acquired adaptive, cognitive, and social functioning in persons with DS usually in adolescence to early adulthood. Initially reported in 1946 as "catatonic psychosis," there has been an increasing interest among the DS community, primary care, and subspecialty providers in this clinical area over the past decade. This condition has a subacute onset and can include symptoms of mood lability, decreased participation in activities of daily living, new-onset insomnia, social withdrawal, autistic-like regression, mutism, and catatonia. The acute phase is followed by a chronic phase in which baseline functioning may not return. No strict criteria or definitive testing is currently available to diagnose DSDD, although a comprehensive psychosocial and medical evaluation is warranted for individuals presenting with such symptoms. The etiology of DSDD is unknown, but in several hypotheses for regression in this population, psychological stress, primary psychiatric disease, and autoimmunity are proposed as potential causes of DSDD. Both psychiatric therapy and immunotherapies have been described as DSDD treatments, with both revealing potential benefit in limited cohorts. In this article, we review the current data regarding clinical phenotypes, differential diagnosis, neurodiagnostic workup, and potential therapeutic options for this unique, most disturbing, and infrequently reported disorder.

Abstract
PURPOSE Current American Academy of Pediatrics guidelines for children with Down syndrome (DS) recommend a complete blood count (CBC) at birth and hemoglobin annually to screen for iron deficiency (ID) and ID anemia (IDA) in low-risk children. We aimed to determine if macrocytosis masks the diagnosis of ID/IDA and to evaluate the utility of biochemical and red blood cell indices for detecting ID/IDA in DS. METHODS We reviewed data from 856 individuals from five DS specialty clinics. Data included hemoglobin, mean corpuscular volume, red cell distribution width (RDW), percent transferrin saturation (TS), ferritin, and c-reactive protein. Receiver operating characteristic curves were calculated. RESULTS Macrocytosis was found in 32% of the sample. If hemoglobin alone was used for screening, all individuals with IDA would have been identified, but ID would have been missed in all subjects. RDW had the highest discriminability of any single test for ID/IDA. The combination of RDW with ferritin or TS led to 100% sensitivity, and RDW combined with ferritin showed the highest discriminability for ID/IDA. CONCLUSION We provide evidence to support that a CBC and ferritin be obtained routinely for children over 1 year old with DS rather than hemoglobin alone for detection of ID.

Abstract
The objective of this study is to evaluate if the diagnosis of a complex congenital heart disease (CHD) was missed in a patient with Down syndrome (DS) who had a fetal echocardiogram that was read as normal. Secondary goal of this study was to determine if any CHD was missed postnatally when a fetal echocardiogram was read as normal. A retrospective chart review of children with DS at Nationwide Children's Hospital whose birthdates were between 1/1/2010 and 12/31/2017 was performed. Patients were included if they had a fetal echocardiogram that was read as normal and also had a postnatal echocardiogram performed. One hundred twenty fetal echocardiograms on patients with DS were performed, of which 45 patients met the inclusion criteria. No patient was diagnosed with a complex CHD postnatally, with a negative predictive value = 100%. Thirteen patients were diagnosed with CHD postnatally, with a negative predictive value of 71.1%. All 13 patients had either a murmur (11) or an abnormal EKG (9). One patient died at 8 days of life due to pulmonary hypertension complications. Five patients had resolution of their CHD, 2 patients have near resolution, 2 patients are being followed for their atrial septal defects and 3 underwent intervention (septum primum surgical repair = 1, PDA catheter occlusion = 2). Complex CHD was not missed on any fetal echocardiograms performed on patients with DS. All the other patients who had CHD diagnosed postnatally had an abnormal finding on evaluation. Further studies evaluating echocardiographic imaging recommendations are needed to maximize care in this patient population.

Abstract
Purpose Pathogenic variants in the chromatin organizer CTCF were previously reported in seven individuals
with a neurodevelopmental disorder (NDD). Methods Through international collaboration we collected data from 39
subjects with variants in CTCF. We performed
transcriptome analysis on RNA from blood samples and utilized Drosophila melanogaster to investigate the impact
of Ctcf dosage alteration on nervous system
development and function. Results The individuals in our cohort carried 2 deletions, 8 likely
gene-disruptive, 2 splice-site, and 20 different missense variants, most of them
de novo. Two cases were familial. The associated phenotype was of variable
severity extending from mild developmental delay or normal IQ to severe
intellectual disability. Feeding difficulties and behavioral abnormalities were
common, and variable other findings including growth restriction and cardiac
defects were observed. RNA-sequencing in five individuals identified 3828
deregulated genes enriched for known NDD genes and biological processes such as
transcriptional regulation. Ctcf dosage
alteration in Drosophila resulted in impaired
gross neurological functioning and learning and memory deficits. Conclusion We significantly broaden the mutational and clinical spectrum ofCTCF-associated NDDs. Our data shed light
onto the functional role of CTCF by identifying deregulated genes and show that
Ctcf alterations result in nervous system defects in Drosophila.

Abstract
OBJECTIVES Established guidelines from the American Academy of Pediatrics for the care of patients with Down syndrome are often not followed. Our goal was to integrate aspects of the guidelines into the electronic health record (EHR) to improve guideline adherence throughout a child's life span. METHODS Two methods of EHR integration with age-based logic were created and implemented in June 2016: (1) a best-practice advisory that prompts an order for referral to genetics; and (2) a health maintenance record that tracks completion of complete blood cell count and/or hemoglobin testing, thyrotropin testing, echocardiogram, and sleep study. Retrospective chart review of patients with Down syndrome and visits to locations with EHR integration (NICUs, primary care centers, and genetics clinics) assessed adherence to the components of EHR integration; the impact was analyzed through statistical process control charts. RESULTS From July 2015 to October 2017, 235 patients with Down syndrome (ages 0 to 32 years) had 466 visits to the EHR integration locations. Baseline adherence for individual components ranged from 51% (sleep study and hemoglobin testing) to 94% (echocardiogram). EHR integration was associated with a shift in adherence to all select recommendations from 61.6% to 77.3% (P < .001) including: genetic counseling, complete blood cell count and/or hemoglobin testing, thyrotropin testing, echocardiogram, and sleep study. CONCLUSIONS Integrating specific aspects of Down syndrome care into the EHR can improve adherence to guideline recommendations that span the life of a child. Future quality improvement should be focused on older children and adults with Down syndrome.

Artif Organs 2018; 42:921-925. [PMID: 29774549 DOI: 10.1111/aor.13160] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Revised: 02/20/2018] [Accepted: 03/19/2018] [Indexed: 12/16/2022]
Abstract
Patients with Down syndrome (DS) may have multiple medical issues that place them at risk for requiring extracorporeal membrane oxygenation. Use of extracorporeal membrane oxygenation in pediatric patients with Down syndrome has been described, but minimal data exist for extracorporeal membrane oxygenation use in adults with Down syndrome. The goal of this study was to describe the clinical characteristics and to determine if there were differences between adult extracorporeal membrane oxygenation patients with Down syndrome that were alive (aDS) versus those that died (dDS) prior to hospital discharge. Patients with Down syndrome that were 18 years and older registered in the Extracorporeal Life Support Organization registry from 1983 to 2016 were analyzed. Demographics and extracorporeal membrane oxygenation characteristics were recorded. A total of 21 adults with Down syndrome were identified. Incidence of extracorporeal membrane oxygenation in adults with Down syndrome was 0.88 per 1000 extracorporeal membrane oxygenation procedures. Hospital mortality was 57.1% (12/21). There were no significant differences between aDS versus dDS for age (24.9 ± 4.8 vs. 28.1 ± 10.2 years), weight (90.7 ± 13.0 vs. 79.1 ± 27.0 kg), gender (4 males vs. 8 males), initial pH (7.18 ± 0.19 vs. 7.27 ± 0.16), or initial pO2 (51.7 ± 13.9 vs. 45.4 ± 19.9), respectively. There were no significant differences between aDS versus dDS in duration of extracorporeal membrane oxygenation run (239 ± 159 h vs. 455 ± 570 h, respectively), ventilator or extracorporeal membrane oxygenation mode, and nitric oxide use. aDS had fewer incidences of mechanical and neurologic complications (41.7% vs. 0.0%, P < 0.05) versus dDS. There were no other significant differences in complication rates between the two groups. Use of extracorporeal membrane oxygenation in the adult population with Down syndrome is significantly less compared to the pediatric population with Down syndrome. Baseline characteristics are not predictive of overall survival. There were minimal differences noted between aDS versus dDS during their extracorporeal membrane oxygenation course. Mortality rates are similar to non-Down syndrome patients placed on extracorporeal membrane oxygenation. Extracorporeal membrane oxygenation may be a reasonable option for adult patients with Down syndrome requiring intensive care.

Abstract
Adults with Down syndrome (DS) are surviving longer, yet data delineating life skills are lacking. As providers are encouraged to provide a "balanced" description of DS to family members/caregivers, more quantitative data are required to accurately describe the abilities and potential of adults with DS. This study assessed health, social, communication, and daily living skills of adults with DS to describe the range of abilities and to show how increasing age contributes to functional abilities. Caregivers of an adult with DS 20 years of age or older participated in an online questionnaire. Descriptive statistics and scores from scales assessed relationships between the number of health issues reported and functional abilities, and how the abilities changed as age increased. Of 188 participants, 157 completed the survey with partial results included. Communication, independence, and social activity scores were compared to the number of congenital and non-congenital health issues reported. Linear regression results showed those with more health issues were significantly less likely to be independent and social. However, only current health issues affected communication skills. No significant correlation occurred between the number of congenital abnormalities and scores for independence/life skills as an adult. T-test by age group found decreasing abilities after 40 years of age. In conclusion, quantitative data and information from this study is beneficial for providers in order to describe the potential for an individual with DS and to assist caregivers to plan accordingly for the future of their adult with DS.

Abstract
Maternal uniparental disomy (UPD) 15 is one of the molecular causes of Prader-Willi syndrome (PWS), a multisystem disorder which presents with neonatal hypotonia and feeding difficulty. Current diagnostic algorithms differ regarding the use of SNP microarray to detect PWS. We retrospectively examined the frequency with which SNP microarray could identify regions of homozygosity (ROH) in patients with PWS. We determined that 7/12 (58%) patients with previously confirmed PWS by methylation analysis and microsatellite-positive UPD studies had ROH (>10 Mb) by SNP microarray. Additional assessment of 5,000 clinical microarrays, performed from 2013 to present, determined that only a single case of ROH for chromosome 15 was not caused by an imprinting disorder or identity by descent. We observed that ROH for chromosome 15 is rarely incidental and strongly associated with hypotonic infants having features of PWS. Although UPD microsatellite studies remain essential to definitively establish the presence of UPD, SNP microarray has important utility in the timely diagnostic algorithm for PWS.

Abstract
BACKGROUND Individuals with Down syndrome have an increased risk for congenital cataracts, but descriptions of surgical, medical and developmental outcomes are sparse. MATERIALS AND METHODS Retrospective review of medical charts of patients with Down syndrome with visits to Cincinnati Children's Hospital from 1988 to 2013 was performed. A case series of five patients with Down syndrome and cataracts is presented. A total of 47 patients with Down syndrome without cataracts were used as a developmental control. Developmental quotients were compared using an independent-sample, unequal variance t-test. RESULTS Post-operative cataract complication rates ranged from 20% to 60%. Visual outcomes were varied; significant associations between complication rate and visual outcome were not found. Developmental quotients did not show an association with number of complications, but were lower for children with Down syndrome with cataracts requiring surgery compared to children with Down syndrome without cataracts. CONCLUSION In children with Down syndrome and congenital cataract, surgical intervention has risk for post-operative complications. Further investigation is needed to determine if there is an association between surgical complications and visual or developmental outcomes.

Abstract
To assess adherence to symptom-based studies recommended in the health supervision guidelines for Down syndrome from the American Academy of Pediatrics (AAP), 24 pediatric care sites participated in retrospective chart review. Symptom-based screening and 4 associated recommendations, including cervical spine radiograph, video swallow study, celiac study with tissue transglutaminase and sleep study were analyzed by reviewing well-child visit notes of 264 children with Down syndrome. Given trends toward symptom-based screens, Pearson's chi-square test and Fisher's exact test were used to determine the association between symptom presence and receiving corresponding symptom-based screens. Adherence rates were widely variable ranging from 0% to 79% completion. Symptom-based studies were performed in 22% to 36% of patients. Symptom screens were documented positive in many patients, but the presence of symptoms did not correlate with completion of symptom-based screens. Symptom-based screening is low; associated studies were performed in patients without documented symptoms contrary to AAP recommendation.
