Evaluation and diagnosis of patients with developmental delay: standardised protocols from the paediatric point of view

Abstract

The identification of the causes of mental retardation (MR) is of great importance because of the consequences it has in the intervention, prognosis, knowledge of risk of recurrence and its prevention. The purpose of this review is to provide a global evaluation of the child with developmental delay or with MR in day-to-day clinical praxis of the neuropaediatrician who has to put aetiological diagnosis in practice. To this end we conduct a review of the evidence-based guidelines published by the leading groups of experts that assess the weight of diagnostic tests in the initial evaluation of children with MR and propose an algorithm that helps the clinician to make decisions. A good patient record including the familial and personal history, the examination and observation of behaviour is essential before starting the laboratory and imaging tests in a rational manner. At the outset, cytogenetic and molecular genetic studies are indicated to study fragile X syndrome and neuroimaging, preferably magnetic resonance, should be employed above all when anomalies are observed in the examination. Ophthalmologic and auditory evaluation is recommended in all cases. Routine metabolic screening is not indicated at the outset; studies to in...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
