Study Notes
Growth and Development
- Growth refers to the increase in mass and dimensions of the body, including weight, length, and head circumference.
- Development is the maturation of functions and acquisition of skills, encompassing motor, mental, and sexual development.
- Growth and development occur simultaneously.
Stages of Prenatal Development
- Embryonic stage lasts for the first 8 weeks.
- Fetal stage spans from the 9th to the 40th week, divided into early (9-24 weeks) and late (25-40 weeks):
- Maximum growth rate during this period accounts for 30% of adult height.
- Factors influencing growth include maternal and placental health, as well as fetal insulin levels.
Factors Affecting Growth
- Excess androgens can lead to tall stature in childhood but short stature in adulthood.
- Adrenal cortisol deficiency can result in failure to thrive and asthenia.
- Excess steroids cause short stature with obesity, seen in conditions such as Cushing syndrome.
- Poor living conditions such as inadequate housing and hygiene can hinder growth.
- Growth hormone deficiency has a significant impact on growth rates.
Monitoring Growth Parameters
- Key parameters: weight, length (or height after age 2), and head circumference are crucial for monitoring growth.
- Other parameters: body proportions, dentition (primary and secondary), vital signs (heart rate, respiratory rate), and bone age (assessed radiologically).
Motor and Mental Development
- Gross motor skills include milestones like sitting, standing, and walking.
- Fine motor skills involve hand and finger coordination.
- Mental development encompasses social skills and verbal communication.
Sexual Development
- Assesses the progression of puberty stages and the development of secondary sexual characteristics.
Physical Growth in Infants
- Normal birth weight ranges between 2.5 kg and 4 kg, with the average around 3 kg.
- MRI can help assess brain abnormalities (e.g., atrophy or calcifications).
Puberity Definition and Onset
- Puberty is marked by morphological and physiological changes; onset varies by genetic, racial, socioeconomic, and nutritional factors:
- Boys typically begin between ages 9-14; girls start between 8-13.
Adolescent Growth Spurt
- Characterized by an acceleration followed by deceleration of growth, culminating in epiphyseal fusion.
Stages of Sexual Maturity Rating in Girls
- Breast development progresses through five stages dictated by estrogen levels, from preadolescent to mature nipple contours.
- Pubic hair development proceeds through five stages, influenced by adrenal androgens.
Stages of Sexual Maturity Rating in Boys
- Testicular and penis growth correlates with pubic and axillary hair development under androgen control.
- Follows a five-stage progression from preadolescent to adult size and quantity of hair.
Disorders Related to Puberty
- Precocious puberty: onset before age 8 in girls or age 9 in boys.
- Types include normal variants (e.g., premature thelarche, which involves early breast development in girls without other signs of puberty) and pubertal gynecomastia in boys, common during puberty.
Summary of Key Points
- Growth and development are interlinked and multifaceted.
- Stages of development can be monitored through various indicators.
- Understanding the shifts in physical, motor, mental, and sexual development is essential for recognizing normal progression and identifying potential disorders.
