Study Notes
Endocrine System
- The adrenal gland primarily secretes steroid hormones.
- The main function of the endocrine system in postnatal growth is to regulate growth and development.
Thyroid Gland
- The isthmus of the thyroid gland lies between the two lobes.
- The thyroid gland secretes amines such as epinephrine.
- Peptide hormones are released from the thyroid gland.
- Thyroid storm is a clinical feature associated with hyperthyroidism.
- An important investigation necessary to confirm the diagnosis of hyperthyroidism is thyroid function studies.
- Graves' disease results in hyperthyroidism.
- The peak incidence age group for Graves' disease is 20-40 years.
- Thyroid scintigraphy confirms the diagnosis of Graves' disease.
- The treatment of choice when medical therapy fails in hyperthyroidism is surgery.
- Thyroid hormone increases the breakdown of nutrients to produce energy.
- Thyroid hormone stimulates the release of T3 and T4.
- Increased circulating levels of thyroid hormone decrease TSH release and TRH production.
- Thyroid hormone plays a role in the development and maintenance of the CNS.
Congenital Hypothyroidism
- A common clinical manifestation of congenital hypothyroidism in infants is excessive sleep, hypotonia, and coarse facies.
- A common respiratory difficulty associated with congenital hypothyroidism is respiratory distress.
- A roentgenograph of skeletal for a newborn with congenital hypothyroidism reveals delayed bone age.
- The treatment of choice for congenital hypothyroidism is hormone replacement therapy.
Diabetes Mellitus
- Type 1 diabetes mellitus is almost always due to autoimmune overproduction of T3 and T4 in children.
- The peak age group for presentation of type 1 diabetes mellitus is 10-14 years.
- Down syndrome is a genetic syndrome associated with type 1 diabetes mellitus.
- Genetic susceptibility is a component of the multifactorial disorder of type 1 diabetes mellitus.
- Vitamin D deficiency is not an environmental factor associated with type 1 diabetes mellitus.
- Prediabetes is defined as a fasting blood glucose level of 100-125 mg/dL.
- Insulin plays a role in reducing blood glucose levels by facilitating glucose uptake in cells.
- The most common clinical presentation for childhood type 1 diabetes is polyuria and polydipsia.
- Diabetic ketoacidosis (DKA) occurs at a blood glucose level of 250 mg/dL.
- DKA is a pediatric emergency due to its rapid progression and potential for mortality.
- Soluble insulin is given subcutaneously at a dose of 0.5-1 units/kg/day 3 times daily in the initial phase of treatment.
- Total dose is given twice daily using about 75% of the daily insulin dose as 2/3rd at breakfast and 1/3rd at dinner in the maintenance phase of treatment.
