Q

Genital Stage 1 Male

A

Prepubertal. Penis, testes, and scrotum are about the same size and proportions as in early childhood. It is important to take into account whether the penis is uncircumsized when assessing penile growth, as the uncircumsized penis may appear larger than it really is.

Q

.Discuss the need for growth charts and their use in clinical practice?

A

The physical growth of infants and children has long been recognized as an important indicator of health and wellness (1,2). Growth charts have been used for at least a century to assess whether a child is receiving adequate nutrition and to screen for potentially inadequate growth that might be indicative of adverse health conditions. Traditionally, attention has focused on undernutrition. However, in the past few decades, concerns about excessive weight gain have increased, and growth charts have been used to screen for overweight, including obesity.

Q

Describe two separate techniques for assessing joint joint stability

A

The Barlow method is an examinaiton method that identifies a loose hip that can be pushed out of the socket with gentle pressure. Approximately 80% of “Barlow Positive” hips will resolve spontaneously in the first few weeks of life. Early treatment may be recommended when the hip is “dislocatable” but minor degrees of instability can be treated with multiple diapers followed by an Ultrasound Study at approximately six weeks of age.

Q

Describe two separate techniques for assessing joint joint stability

A

The Ortolani method is an examination method that identifies a dislocated hip that can be reduced into the socket (acetabulum). Ortolani described the feeling of reduction as a “Hip Click” - a sound instead of a sensation of the hip moving over the edge of the socket when it re-located. After the age of six weeks, this sensation is rarely detectable and should not be confused with snapping that is common and can occur in stable hips when ligaments in and around the hip create clicking noises. When the Ortolani test is positive because the hip is dislocated, treatment is recommended to keep the hip in the socket until stability has been established

Louder when supine or with fever or tachycardia. Usual onset age 2-6yo may persist through adolescence. Benign condition.

75
Q

Venous Hum(location and sound)-

A

grade 1-2/6 continuous musical hum heard best at URSB and ULS and lower neck. Disappears in supine position, or with turning head when jugular vein is compressed. Common after 3 yo. Produced by turbulence in subclavian and jugular veins. Benign condition.

76
Q

Innocent murmur-

A

Most murmurs in infants and children originate through normal flow patterns with no structural or anatomic abnormalities of the heart or vessels. Most are heard in 3-4 year olds, change in sound with changes in position.

77
Q

SBE prophylaxis(sub-acute bacterial endocarditis)-

A

The new guidelines emphasize the need of optimal dental hygiene with regular dental brushing, at least 2-3 times a day, and flossing along with regular dental appointments. Antibiotic for Prosthetic cardiac valve or prosthetic material used for cardiac valve repair,Previous IE,Congenital heart disease (CHD),Unrepaired cyanotic CHD, including palliative shunts and conduits,Completely repaired congenital heart defect with prosthetic material or device, whether placed by surgery or by catheter intervention, during the first 6 months after the procedure,Repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or prosthetic device (which inhibit othelialization), Cardiac transplantation recipients who develop cardiac valvulopathy;Except for the conditions listed above, antibiotic prophylaxis is no longer recommended for any other form of CHD. †Prophylaxis is reasonable because endothelialization of prosthetic material occurs within 6 months after the procedure.

78
Q

Diagnosis of hypertension in children:

A

Blood pressure falls into several categories. ••Prehypertension is systolic BP and/or diastolic BP ≥90th percentile but 5 mm Hg above the 99th percentile (>99th percentile + 5 mm Hg). Left ventricular hypertrophy, the most prominent finding, is present in up to 36% of hypertensive children.

79
Q

SVT clinical presentation

A

; infants with irritability, poor feeding, sweating, poor coloration of skin, and who exhibit a pulse rate of 200-250 beats per minute. •Palpitations (the sensation of the heart pounding in the chest)•Dizziness, light-headedness (near-faint), or fainting•Shortness of breath• Anxiety•Chest pain or tightness.

80
Q

Hypercholesterolemia criteria;

A

Screening factors• Consume excessive saturated fats • Elevated blood pressure • Diabetes • Physical inactivity • Renal disease • Body mass index at or above the 85th percentile • Unobtainable family history or any factors for coronary artery disease
Borderline- total cholesterol 170-199, LDL 110-129
High- total cholesterol > 200, LDL ≥130, triglycerides > 150

81
Q

Syncopal episodes in children presentation;

A

brief sudden LOC resulting in decreased postural tone, collapse and spontaneous recovery. May be preceded by diaphoresis, pallor, dizziness, blurred/tunnel vision, nausea, feeling hot, buzzing in the ears or muffled sounds.

82
Q

Syncopal episodes in children presentation;

A

Most in children are benign alteration in vasomotor tone (neurocardiogenic). Vasovagal(Vasodepressor) syncope- Hypotension without immediate compensatory heart rate increase. Cardioinhibitory syncope- BP drops as heart rate drops. Mechanism is excessive vagal tone. Reflex bradycardia often associated with cough, swallowing, hair combing, carotid pressure or micturition.

83
Q

POTS (Postural Orthostatic Tachycardia Syndrome)

A

mild form of a primary dyautonomia, exaggerated sinus tachycardia within 10 min of up right posture, > 30 bpm above resting heart rate. Orthostatic intolerance. c/o fatigue, exercise intolerance, lightedness, heat intolerance, chronic anxiety, mood swings and panic attacks. 10% progress to Pure Autonomic Failure. Usually self resolve by adulthood.

84
Q

Causes of Noncardiac Syncope

A

Seizures, atypical migraines, drugs, metabolic, hypoglycemia, hyperventilation syndrome, pregnancy, vertigo

85
Q

Arrhythmias & Conduction disorders-

A

Vtach (Arrhythmogenic right ventricular cardiomyopathy), SVT (pre-excitation WPW), Heart block- cogential (SLE), Acquired (post-op, infections, lyme disease,

86
Q

Child maltreatment-

A

does the presentation fit the clinical finding- if not need to be reported.
Factors associated with child maltreatment include
A child who is perceived by parents to be demanding or difficult to satisfy
An infant who is diagnosed with a chronic illness or disability
A family who is socially isolated, without community support
Mental health issues with one or both parents that have not been diagnosed & treated
A parent with career difficulties, who may see the newborn as an impediment or burden

87
Q

Child maltreatment-

A

If abuse is suspected, the health care professional should ask direct questions in a respectful way to determine whether any kind of abuse might be occurring. Any unexplained bruises or other signs of abuse should be thoroughly investigated. Abuse and neglect at this early stage have long-term effects on brain and development and increase the likelihood of behavior disorders in the child. Infant and toddlers are at higher risk for abuse and neglect than older children. Children who are younger than 3 years account for more than 1/3 maltreated children and 41% of fatally abused children are younger than 1 year.

88
Q

Causative factors of myocarditis;

A

Myocarditis is rare in young children. It is slightly more common in older children and adults. It tends to be more severe in newborns and young infants than in children over age 2. In children it is usually caused by viruses that reach the heart, such as the influenza (flu) virus, Coxsackie virus, parovirus, and adenovirus. However, it may also be caused by bacterial infections, including Lyme disease. Other causes of pediatric myocarditis include:•Allergic reactions to certain medications•Exposure to certain chemicals in the environment•Infections due to fungus or parasites•Radiation•Some diseases (autoimmune disorders) that cause inflammation throughout the body•Some drugs

Q

Complication of Jaundice

A

visual estimation of degree of jaundice is not reliable. Closely monitor the < 38 week, breast feeding. Treatment when indicated with phototherapy or exchange transfusion. (at window undressed tid for 10 minutes). Bilirubin is toxic to cells of the brain. If a baby has severe jaundice, there’s a risk of bilirubin passing into the brain, a condition called acute bilirubin encephalopathy. Clinical indications Listlessness or difficulty waking,High-pitched crying,Poor sucking or feeding, Backward arching of the neck and body,Fever &Vomiting.

104
Q

Kernicterus

A

is the syndrome that occurs if acute bilirubin encephalopathy causes permanent damage to the brain with clinical symptoms such as Involuntary and uncontrolled movements (athetoid cerebral palsy), Permanent upward gaze, Hearing loss, improper development of tooth enamel.

105
Q

Eyes

A

Check for red reflex, Strabismus- alignment of eye important correlation with brain development.
Eyes assessment for pupillary size, equality, reaction to light, accommodation, visual acuity.
Vision screen 3-4yrs, Visual acuity 3-5yr is 20/40, age 8 years 20/20. E chart & strabismus check for preschool children. Snellen charts for older children.

106
Q

Amblyopia (lazy eye).

A

EOM’s- tracking 6 fields of vision.

107
Q

Strabismus (esotopia, exotropia)-

A

muscle imbalance test for corneal light reflex- cover/uncover.

108
Q

Conjunctivitis-

A

a red flag in the newborn may be STD from birth, preschool is # one reason they are sent home. Inflammation of eye – history of juvenile arthritis.

109
Q

Eye Variations:

Placement & symmetry

A

Wide set (hypertelorism) – Down Syndrome
Close set (hypotelorism)
Epicanthal folds or upward slants- ethnicity, Down Syndrome
Character of eyebrows

110
Q

Eye Variations: Eyelids

A

Ptosis, lid lag, blepharitis (stye), swelling
Dacryocystitis (blocked tear duct) may cause redness, swelling and discharge.
Allergic shiner- dark circles may indicate allergy
Perorbital edema may indicate renal problems
Sunken eyes may indicate dehydration

111
Q

Eye Variations: Sclera

A

Jaundice (liver dz), injection (conjunctivitis),

Hemorrhage, blue color (osteogenesis imperfect)

112
Q

Eye Variations: Conjunctive

A

Inflammation, pallor (anemia)

Cobblestone appearance may indicate allergy

113
Q

Eye Variations: Cornea

A

Smooth, moist, clear (not injected with conjunctivitis red eye)

114
Q

Eye Variations: Pupil & Iris

A

Brushfield’s spot (light speckling of iris) seen in Down’s

Coloboma (notch at outer edge or iris) may indicate visual field defect

115
Q

Eye Variations: Othalmoscope

A

partial or dark red reflex, indicates pathology, various retinal anomalies or opacities of cornea, anterior chamber or lens (cataract).
White retinal reflex indicates pathology (retinoblastoma, retinal detachment, chorioretinitis)
Retinal hemorrhage is pathology, associated with a variety of causes: is a specific diagnostic criteria in shaken baby syndrome.
Papilledema of increased ICP more likely in older children, with closed cranial sutures.
