This chapter focuses on endocrine disorders in childhood. It brings together the quintessential knowledge on conditions that directly determine a child's physical, intellectual, and sexual development.
The section is structurally divided into several blocks. The main emphasis is placed on carbohydrate metabolism disorders: we thoroughly examine all types of diabetes mellitus, diagnostic principles, insulin therapy regimens, and complication management. The second important block covers thyroid pathology, including iodine deficiency, hypothyroidism, and types of goiter. The third encompasses physical development issues (growth retardation, tall stature), puberty disorders, childhood obesity, and Cushing's syndrome. As a basic anatomical and physiological reference, the section also includes the morphology and physiology of the spleen.
In practical classes, instructors most commonly ask about the differential diagnosis of growth retardation, insulin dose calculation, and emergency management algorithms for diabetes. Pay special attention to them—this is the knowledge required of an on-call physician in the first minutes of patient admission.
What is the main diagnostic criterion for diabetes mellitus?
A persistent (chronic) increase in blood glucose levels, which is called hyperglycemia.
Why does severe thirst occur in type 1 diabetes mellitus?
Polydipsia (excessive thirst) occurs due to cellular dehydration. The body attempts to dilute the high glucose concentration in the bloodstream by drawing fluid from cells and tissues.
What is the main difference between specific types of diabetes and others?
Specific types have a strictly established etiology, whether it is a genetic mutation, pancreatectomy, or an excess of counterregulatory hormones.
Why is type 2 diabetes mellitus in children often diagnosed incidentally?
The disease manifests gradually and has a subclinical picture. Glucose levels can remain within prediabetic ranges for a long time, which is why carbohydrate metabolism changes are often discovered only during routine preventive examinations.
In which type of blood are standard diagnostic criteria for diabetes determined?
In venous plasma. For whole capillary blood, fasting reference values are lower (normal <5.6 mmol/L).
What is the essence of basal-bolus insulin therapy?
This is a treatment regimen consisting of administering long-acting insulin to meet baseline requirements (basal) and ultra-short-acting injections before meals to metabolize carbohydrates (bolus). It mimics the function of a healthy pancreas as closely as possible.
