Child Development I Flashcards

1
Q

Growth

A

Growth refers to increase in physical size and dimensions, i.e. gain in ht, wt, and head circumference with advancement in age.Transient shifts may occur between 4-18 months but a child should reach a stable rate by 1.5 years of age.

Upper motor neuron lesions.

Q

Growth in Relation to Health

A

The rate of growth rather than absolute size is a sensitive indicator of health or disease. Therefore, all parameters should be measured in a serially consistent manner and recorded in a growth chart. If a child has values outside ± 2 SD range on a normal distribution curve or a continued and unexplained shift in growth trend indicates a need for evaluation.

Q

Certain childhood illnesses or conditions may affect growth:

A 
‐Neurologic impairment/CP
‐Oro-­‐motor dysfunction (leading to FTT)
‐Endocrine dysfunction
‐Skeletal disease
‐Genetic condition (like Down Syndrome)

Children with Down Syndrome are typically at or near 3rd percentile for general population. Their average adult height is 5 ft for men, 4.5 ft for women.

Q

The Importance of Head Circumference

A

The average head circumference is 34-35 cm at birth. It increases by 12 cm in the first year (46-47 cm).

Head circumference should be measured up until 3 yrs of age and thereafter if CNS pathology is suspected. A rapid increase in head size during the first year reflects normal growth and maturation of brain.

Q

Height

A

The average length of FT is 50 cm. Length increases by 50% in first 12 months. The average growth is 12 cm in the 2nd year and 6-8 cm annually from 3-5 years of age. Adult height can be estimated by doubling the length at 2 years of age.

Q

Changes in Height: Boys vs Girls

A

Girls attain maximal growth velocity before menarche and attain ultimate height 2 years after menarche. Boys grow fastest in late puberty concurrent with appearance of facial hair.

Q

Height Predictions in Children with Defects

A

For children with marked deformity of the spine or lower extremity, height prediction can be obtained by measuring arm span. With significant bilateral atrophy of lower extremities due to lower motor neural lesion, a sitting height may be a better indicator of general growth than total height.

Q

Weight

A

Average FT neonate weighs approximately 3400 gm (range 2500/4600 gms). < 2500 gm are classified as low-birth-weight infants.

Babies lose up to 10% of body weight during 1st week of life. Weight Gain after 2nd week is about 1 oz every day during first 3 – 4 months. Weight is doubled by 5 – 6 months and tripled by 1 year of age.

During 2nd year of life average weight gain is about 2.5 kg (5.5 lbs) and 2 kg (4.5 lbs) annually from 3 – 5 years of age

Q

Variations in Development

A

Under normal circumstances achievement of milestones has a predictable pattern. Individual variations may occur in the timing than in the process of sequences. Delays in milestones and areas of involvement will guide you to a diagnosis and management

Q

Newborn Period:

A

Muscle tone is predominantly with semiflexion of the extremities. When in prone position head turns from side to side with neck hyper extension. Sweeping mouth against the surface.

Most movements in this period are involuntary and purposeless. Primitive Reflexes are present

If you put them in sitting position, full support is required, the back is rounded and head falls forward. Hands are loosely fisted and grasp reflexes can be elicited.

Temperament characteristics are discernible during first few months and contribute to parent child interaction

Q

Infantile Reflex Development

A

Motor behavior in infancy is influenced by primitive reflexes (as CNS is immature). The reflexes produce a predictable and stereotypic movement. As neuromaturation occurs these primitive reflexes are suppressed and become part of mature reflex system.

50% resolve by 4 à 90% by 6 yo

Treatment: Parent education

81
Q

Parasomnias

A

Night Terrors & Nightmares

82
Q

A

Occur in 3% of children. 3-12 year-old (median onset 3.5).
Occur 15-60 minutes after going to sleep. Non-REM sleep.

Presentation: Poorly consolable, amnesia for event

Prevention/Treatment: Reassurance, Environmental measures, Scheduled awakening

83
Q

Nightmares

A

25-50% of 3-5 year olds. Onset in latter part of the night. REM sleep.

84
Q

Developmental Disorders Prevalence:

A

12-22% of American children with 70%-80% not detected in primary care.

Providers ideally should refer (~ 1 of 6 pts)

85
Q

HOW to assess development?

A

Surveillance, Screening (Denver, ASQ), Evaluation (refer for specific evaluation), Diagnosis

86
Q

Parachute Reflex

A

As the examiner allows the child to free fall in ventral suspension, the child’s extremities extend symmetrically to distribute his weight over a broader and more stable base on landing.

87
Q

Feeding disorders

A

The common denominator of feeding disorders is usually food refusal. Infants and young children may refuse to eat if they find eating painful or frightening. They may have had unpleasant experiences (emotional or physiologic) associated with eating, they may be depressed, or they may be engaged in a developmental conflict with the caregiver that is being played out in the arena of feeding.

The infant may refuse to eat if the rhythm of the feeding experience with the caregiver is not harmonious.

88
Q

Management of Feeding Disorders

A

The goal of intervention is to identify factors contributing to the disturbance and to work to overcome them. The parents may be encouraged to view the child’s behavior differently and try not to impose their expectations and desires. Alternatively, the child’s behavior may need to be modified so that the parents can provide adequate nurturing.

When the chief complaint is failure to gain weight, a different approach is required.

89
Q

Excessive weight loss may be due to:

A

Malnutrition, vomiting or diarrhea, to malabsorption, or to a combination of these factors.

90
Q

The Denver Developmental Screening Test (DDST)

A

A widely used assessment for examining children 0-6 years of age as to their developmental progress. The scale reflects what percentage of a certain age group is able to perform a certain task. A subject’s performance against the regular age distribution is noted. Tasks are grouped into four categories (social contact, fine motor skill, language, and gross motor skill) .

91
Q

When should a stable rate of growth be reached?

A

1.5 yo

92
Q

LBW in grams

A

<2500 gm is classified as LBW

93
Q

Weight Gain in Infants

A

Should double in 5-6 mo and triple in 1 yr. (1 oz per day for first 3-4 mo)

94
Q

What is the earliest indicator of neuro-abnormality?

A

obligatory or persistent primitive reflexes

95
Q

Cerebral Palsy

A

Cerebral palsy is a disorder of movement, muscle tone or posture that is caused by an insult to the immature, developing brain, most often before birth.

96
Q

Symptoms of Cerebral Palsy

A

Variations in muscle tone, such as being either too stiff or too floppy

Stiff muscles and exaggerated reflexes (spasticity) or normal reflexes (rigidity)

Lack of muscle coordination (ataxia)

Tremors or involuntary movements/Slow, writhing movements (athetosis)

Favoring one side of the body, such as reaching with only one hand or dragging a leg while crawling

Excessive drooling or problems with swallowing

97
Q

Diagnosis of Cerebral Palsy

A

Developmental Monitoring, Developmental Screening & Developmental and Medical Evaluations

98
Q

Treatment of Cerebral Palsy

A

Cerebral palsy can’t be cured, but treatment will often improve a child’s capabilities. Many children go on to enjoy near-normal adult lives if their disabilities are properly managed.

THERAPY

99
Q

A

50% can’t walk by them selves
