Clinical and Molecular Diagnosis in Muscular Dystrophies

Muscular dystrophies are a diverse group of inherited muscle disorders with a wide range of clinical manifestations from a severe form with early onset and early death to adult forms with later onset and minimal clinical manifestation that do not affect life-span. Overlapping clinical symptoms and the multitude of genes that need to be analyzed for an accurate characterization make the diagnosis hard. In next-generation sequencing era, a lot of used assay in molecular diagnostics must be taken into consideration for muscular dystrophy diagnosis. However, for more accurate diagnosis, muscle protein expressions analysis may have prognostic value. In this chapter, we present the most important clinical and laboratory findings in the most common forms of muscular dystrophies and molecular diagnostic approaches for a more accurate diagnosis

First-Tier Array CGH in Clinically Variable Entity Diagnosis: 22q13.3 Deletion Syndrome

Phelan-McDermid (PMS) or 22q13 deletion syndrome (OMIM 606232) is a rare genetic disorder with highly variable clinical presentation. The phenotype includes generalized neonatal hypotonia, developmental delay with intellectual disability and delayed speech, mild dysmorphic features, and autistic behavior. The genetic defects of PMS consist of 22q13.3 deletions or chromosomal structural rearrangements involving SHANK3 gene; the loss of function mutations of SHANK3 gene was reported in a minority of cases. The 22q13.3 deletions vary in size, from 0.2 to over 9 Mb, and, although larger deletions are generally associated with more severe phenotypes, the genotype-phenotype correlations are not clear-cut for all patients. SHANK3 is considered the main candidate gene for the neurologic features of PMS. PMS is a rare disorder, often underdiagnosed. There are no established clinical diagnostic criteria for PMS. The genetic tests typically used are chromosomal microarray and multiplex ligation-dependent probe amplification (MLPA) or fluorescent in situ hybridization (FISH) for copy number analysis of SHANK3 gene; next-generation sequencing (NGS) or Sanger sequencing is used for pathogenic mutation screening of SHANK3. In this chapter, we report three cases with PMS and summarize the clinical and genetic diagnostic approaches of this condition, highlighting the role of chromosomal microarray technology in the identification of rare, but significantly impacting patient’s life, DNA copy number abnormalities

Myalgic encephalomyelitis/chronic fatigue Syndrome (ME/CFS): Investigating care practices pointed out to disparities in diagnosis and treatment across European Union.

ME/CFS is a chronic, complex, multisystem disease that often limits the health and functioning of the affected patients. Diagnosing patients with ME/CFS is a challenge, and many different case definitions exist and are used in clinical practice and research. Even after diagnosis, medical treatment is very challenging. Symptom relief and coping may affect how patients live with their disease and their quality of life. There is no consensus on which diagnostic criteria should be used and which treatment strategies can be recommended for patients. The purpose of the current project was to map the landscape of the Euromene countries in respect of national guidelines and recommendations for case definition, diagnosis and clinical approaches for ME/CFS patients. A 23 items questionnaire was sent out by email to the members of Euromene. The form contained questions on existing guidelines for case definitions, treatment/management of the disease, tests and questionnaires applied, and the prioritization of information for data sampling in research. We obtained information from 17 countries. Five countries reported having national guidelines for diagnosis, and five countries reported having guidelines for clinical approaches. For diagnostic purposes, the Fukuda criteria were most often recommended, and also the Canadian Consensus criteria, the International Consensus Criteria and the Oxford criteria were used. A mix of diagnostic criteria was applied within those countries having no guidelines. Many different questionnaires and tests were used for symptom registration and diagnostic investigation. For symptom relief, pain and anti-depressive medication were most often recommended. Cognitive Behavioral Therapy and Graded Exercise treatment were often recommended as disease management and rehabilitative/palliative strategies. The lack of consistency in recommendations across European countries urges the development of regulations, guidance and standards. The results of this study will contribute to the harmonization of diagnostic criteria and treatment for ME/CFS in Europe

Autistic Adult Services Availability, Preferences, and User Experiences : Results From the Autism Spectrum Disorder in the European Union Survey

There is very little knowledge regarding autistic adult services, practices, and delivery. The study objective was to improve understanding of current services and practices for autistic adults and opportunities for improvement as part of the Autism Spectrum Disorder in the European Union (ASDEU) project. Separate survey versions were created for autistic adults, carers of autistic adults, and professionals in adult services. 2,009 persons responded to the survey and 1,085 (54%) of them completed at least one of the services sections: 469 autistic adults (65% female; 55% 50% responded "don't know"). Five of seven residential services features recommended for autistic adults were experienced byPeer reviewe

Autistic Adult Health and Professional Perceptions of It: Evidence From the ASDEU Project

The Autism Spectrum Disorders in the European Union (ASDEU) survey investigated the knowledge and health service experiences of users and providers to generate new hypotheses and scientific investigations that would contribute to improvement in health care for autistic adults. An online survey designed for autistic adults, carers of autistic adults, and professionals in adult services was translated into 11 languages and distributed electronically by organizations and in-country adult service facilities in 2017; 522 autistic adults, 442 carers, and 113 professionals provided answers to the health questions. Professionals, the majority in non-medical services, appeared to be poorly informed about whether certain co-occurring conditions were more frequent in autistic adults than typical adults-especially some medical conditions, suicide attempts, accidents, and pain. A minority of autistic adults reported preventive health behaviors such as routine health check-ups. The majority of users and providers expressed the desire to make health care services more user-friendly for autistic adults. Among the three groups, <20% of responders knew an organization or clinician which has developed a way to monitor health, and prevent poor health, that works well for adults on the autism spectrum. The results point to means for better management of co-occurring conditions associated with autism in adulthood in order to reduce hospital admissions and potential areas of improvement in health and social services for autistic adults. Specifically, efforts should be focused on (1) professionals' education on risks for co-occurring conditions in autistic adults; (2) promoting preventive health behaviors; (3) making services user-friendly for autistic adults and their families; and (4) encouraging knowledge of good local services

Monoclonal antibodies — a revolutionary therapy in multiple sclerosis

Introduction. Multiple sclerosis (MS) has an increasing incidence and affects a young s egment of t he population, having a major impact on patients and consequently on society. The multifactorial aetiology and pathogenesis of this disease are incompletely known at present, but autoimmune aggression has a documented mechanism.State of the art. Since the 1990s, immunomodulatory drugs of high efficacy and a good safety profile have been launched. But the concept of NEDA (No Evidence of Disease Activity) remains the target to achieve. Thus, the new revolutionary class of monoclonal antibodies (moAbs) used in multiple medical fields, from this perspective represents a challenge even for multiple sclerosis, including the primary progressive form, for which there has been no treatment until recently.Clinical implications. In this article, we will review monoclonal antibodies’ use for MS, presenting their advantages and disadvantages, based on data accumulated since 2004 when the first monoclonal antibody was approved for active forms of the disease.Future directions. There is still a need for personalised medicines, with a specific target, which should have fewer adverse effects and drug interactions

The Moderating Role of Emotional Regulation on the Relationship between School Results and Personal Characteristics of Pupils with Attention Deficit/Hyperactivity Disorder

This study aimed to explore the possible moderating role of emotional regulation in the relationship between problem-solving ability, visuomotor precision and visuospatial integration on the one hand and school results on the other in pupils with ADHD. A total of 241 pupils with ADHD (study group) and 207 children without ADHD (control group) were included in our research. Specific tests for the evaluation of the problem-solving ability, visuomotor precision, visuospatial integration, and emotional regulation were applied. The results showed that emotional regulation is a significant moderator of the relationship between school results and problem-solving ability, visuomotor precision, visuospatial integration, and working memory. There are statistically significant differences depending on emotional regulation, visuomotor precision, visuospatial integration, problem-solving ability and working memory in terms of school results of students with ADHD compared to children without this diagnosis. These results can be used in the development of intervention programs

KEYPOINTS IN INVESTIGATING THE CHILD WITH GLOBAL DEVELOPMENTAL DELAY AND INTELLECTUAL DISABILITY

Objective. This paper highlights the main lines of etiological investigation of global developmental delay (GDD), mental retardation (MR) or intellectual disability (ID) and their specifi c order. GDD and MR/ID are chronic entities with onset during the developmental period, affecting personal, social, academic, occupational functions. Elucidating the etiology is important for establishing the management, for assessing the outcome, the recurrence risk, potential opportunities for prevention and for decreasing the psycho-emotional impact on families. Material and method. Relevant literature was reviewed, currently being published recommendations for the diagnostic approach of children with GDD/MR, starting with a thorough history, a thorough clinical examination, then formulating a suspected etiology and including genetic, metabolic, neuroimaging testing. Results and conclusions. Advances in genetics have changed the approach of children with unexplained GDD, increasing the rate of pathogenic chromosomal abnormalities identifi cation. Comparative genomic hybridization is recommended as fi rst-line investigation, with karyotyping as complementary. Sequencing allows the study of many genes involved in GDD and genetic consultation prioritizes the investigations. The identifi cation of the etiologic diagnosis offers the possibility of establishing anticipatory, individualized management plans, in order to limit the complications and associated comorbidities, thereby improving the quality of life
