Clinical examination is not an accurate method of defining the presence of goitre in schoolchildren

Abstract

There are few published data on thyroid size and body size variables in children. We aimed to develop an index for normal thyroid size in schoolchildren using ultrasonography and to evaluate the accuracy of clinical examination in the diagnosis of goitre. A study to screen and diagnose goitre. A population based sample of 1094 schoolchildren aged 6-14 years (556 boys and 538 girls) were submitted to clinical examination of the thyroid. One hundred and nineteen were considered to have goitre. Ultrasonography was performed in 85 who agreed to participate in the study and in 62 schoolchildren selected randomly from those thought to have no goitre. Clinical examination and definition of goitre were performed according to WHO criteria. Thyroid volume was measured by ultrasonography (7-5 MHz transducer). The gland volume of 62 schoolchildren without goitre on clinical examination showed a positive correlation with body surface area, age and skinfold thickness. When these factors were entered in multiple regression analysis, only body surface area remained associated with thyroid volume. The upper limit (95th percentile) of the ratio of thyroid volume to body surface area (Ecobody index) was 6.2 ml/m2. Taking this index as the standar...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.
