Insights

Idiopathic short stature (ISS) affects children with short height, excluding constitutional delay. Growth hormone therapy (rhGH) is effective for catch-up growth in these children.

Area of Science:

  • Pediatric Endocrinology
  • Growth Disorders

Context:

  • Short stature is a primary reason for pediatric endocrinology consultations.
  • Characterized by decreased growth velocity and short height, it encompasses various conditions.
  • Idiopathic short stature (ISS) is diagnosed when known causes are excluded in children below -2 SD height for age and sex.

Purpose:

  • To define Idiopathic Short Stature (ISS) within the differential diagnosis of short stature.
  • To highlight the potential benefit of recombinant human Growth Hormone (rhGH) therapy for ISS.

Summary:

  • ISS affects children with short stature (less than -2 SD) where other causes are ruled out.
  • Constitutional delay of growth and development is excluded from the ISS diagnosis.
  • Clinical trials confirm the efficacy of rhGH treatment for achieving catch-up growth in children with ISS.

Impact:

  • Recognizing ISS is crucial for appropriate diagnosis and management of short stature.
  • rhGH therapy offers a viable treatment option for children with ISS, promoting improved growth outcomes.
  • This understanding aids pediatric endocrinologists in identifying patients who may benefit from growth hormone intervention.

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Polygenic Traits01:18

Polygenic Traits

When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
Dosage Regimen: Individualization01:24

Dosage Regimen: Individualization

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...
Anorexia Nervosa01:28

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...
