Communication, cognitive development and behavior in children with Cornelia de Lange Syndrome (CdLS): Preliminary results

In this study, we present preliminary data on cognitive, behavioral and communication domains of individuals with Cornelia de Lange Syndrome (CdLS), collected through a specific protocol combining direct and indirect tools. Seventeen subjects with CdLS were assessed, 2.5‐ to 13.4‐year‐old. Cognitive level of the subjects differed from what previously described in literature, showing more patients with normal or borderline cognitive abilities. We found a relation between severe autistic behavior and comprehension impairments: all children with high CARS score have severe receptive language disability. A correlation was also found between CARS score and ID: high CARS score occurred only in patients with profound levels of ID. Results of this study support the need for a specific assessment protocol tailored for the characteristics of subjects with multiple disabilities, to be able to identify their strengths avoiding the avalanche effect of weaknesses. Most tests on neuropsychological functions have been developed and standardized for typically developing children, and require the integrity of other functions aside the one that is evaluated, determining an underestimation of the level of functioning. This study could be a starting point to develop new models applicable to other genetic syndromes and complex situations; new and wider studies are needed in order to allow a more complete and accurate assessment, thereby ensuring more efficient and family‐centered treatment plans.

A Regional ADHD Center-Based Network Project for the Diagnosis and Treatment of Children and Adolescents With ADHD.

Objective: We aimed to define the sociodemographic, clinical, and prescription profiles of the participants enrolled in the Italian Lombardy ADHD Register. Method: Data on patients evaluated by the 18 regional ADHD reference centers in the 2012 to 2013 period were analyzed. Results: Seven hundred fifty-three of 1,150 (65%) suspected patients received a diagnosis of ADHD. In 24% of cases, there was a family history of ADHD. Four hundred eighty-three (64%) patients had at least one psychopathological disorder, the more common of which were learning disorders (35%). Eighty-four percent of patients received a prescription for psychoeducational interventions, 2% received only pharmacological treatment, and 14% a combination of both. Compared with patients treated with psychoeducational intervention alone, patients with drug prescriptions more commonly presented values of Clinical Global Impressions - Severity scale (CGI-S) of 5 or higher (p < .0001). Conclusion: A continuous and systematic monitoring of patterns of care is essential in promoting significant improvements in clinical practice and ensuring an efficient and homogeneous quality of care.

Diagnosis and management of Cornelia de Lange syndrome: first international consensus statement

Cornelia de Lange syndrome (CdLS) is an archetypical genetic syndrome that is characterized by intellectual disability, well-defined facial features, upper limb anomalies and atypical growth, among numerous other signs and symptoms. It is caused by variants in any one of seven genes, all of which have a structural or regulatory function in the cohesin complex. Although recent advances in next-generation sequencing have improved molecular diagnostics, marked heterogeneity exists in clinical and molecular diagnostic approaches and care practices worldwide. Here, we outline a series of recommendations that document the consensus of a group of international experts on clinical diagnostic criteria, both for classic CdLS and non-classic CdLS phenotypes, molecular investigations, long-term management and care planning.Cornelia de Lange syndrome is a genetic disorder affecting multiple organ systems that exhibits great phenotypic heterogeneity. This Consensus Statement summarizes recommendations for the diagnosis and management of patients with Cornelia de Lange syndrome.

Rubinstein-Taybi syndrome: New neuroradiological and neuropsychiatric insights from a multidisciplinary approach

Rubinstein–Taybi syndrome is a rare, autosomal dominant, plurimalformative disorder that is clinically characterized by intellectual disability and a wide spectrum of congenital anomalies; facial dysmorphisms are typical, and broad thumbs and great toes are particularly distinctive. Its genetic basis is only partially known, with a detection rate of approximately 65–70%; specifically, microdeletions or mutations in the CREBBP or EP300 genes can be found. Much is known about its clinical features and health‐care protocols, but some areas of clinical knowledge are currently unsolved. In particular, few efforts have been made until now to understand the variability in the neuropsychological and neurobehavioral profile and to deepen knowledge of the neuroradiological malformative pattern. Consequently, little is known about the possible genotype‐phenotype correlations of these issues. Here, we report clinical and genetic data from a cohort of 23 RSTS Italian patients. The most common features in brain magnetic resonance imaging (MRI) were dysmorphic aspects of the corpus callosum (73.6%) with or without minor dysmorphisms of cerebellar vermis, periventricular posterior white matter hyperintensity, and other less common anomalies. The most interesting feature on the whole spine MRI scans was the tendency for a low‐lying conus medullaris without terminal filum thickening. These data will help to improve neuropsychiatric and neuroradiological knowledge and highlight specific genotype‐phenotype correlations.
