PKU
presentation
advice for pregnant women with PKU

A

normal at birth
then fail to attain early developmental milestones
develop microcephaly
progressive cognitive impairment
seizures
albinism
musty odor of sweat and urine (due to phenylacetate).

pregnant women with PKU, maintain low phenylanine levels to protect the developing fetus. Though the developing fetus may only be a carrier of the PKU gene, high intrauterine levels of phenylalanine can result in growth retardation, microcephaly, intellectual disability and congenital heart disease for the child.

So get newborn screening

3-day-old has become lethargic and doesn’t want to feed. She has vomited twice and is showing no interest in feeding. On physical exam you note a lethargic infant with an enlarged liver Hyperammonemia and elevated urine orotic acid
26
wheezing in infant think... give bronchodilators and steroids?
viral respiratory infection eg RSV - can cause airway inflammation and wheezing in infants maybe asthma if strong family history and clear response to bronchodilators but IN GENERAL bonchodilators and steroids are NOT helpful in wheezing infants with VIRAL respiratory illness
27
3 hallmarks of asthma
Airway inflammation Mucus hypersecretion, and Reversible airflow obstruction due to bronchoconstriction. ? Remodeling - some evidence suggests that smooth muscle hyperplasia and hypertrophy develop in the setting of longstanding asthma.
28
1 sentence summary of clinical manifestation of asthma in majority of children
recurrent coughing and/or wheezing that is responsive to bronchodilators (such as beta-agonists) and to anti-inflammatory medications (such as steroids).
29
triggers for peds asthma (bronchoconstriction)
URTI most often ``` also allergies cold air exercise smoke exposure ```
30
diagnose asthma in peds
child with symptoms of asthma who responds to therapy for asthma and has no other identifiable cause for wheezing has asthma by definition, regardless of age.
31
asthma vs RAD reactive airway disease
Many children with wheezing early in life do not continue to wheeze beyond 2 to 3 years. Many physicians are therefore reluctant to make a diagnosis of asthma in very young children, fearing that a child would be persistently labeled as having asthma when in fact their symptoms of this condition have resolved. Some physicians prefer to use the term "reactive airways disease" (RAD) when children appear to have signs and symptoms of underlying airway hyperresponsiveness that is characteristic of asthma, but in whom a diagnosis of asthma is not yet definite. The use of this term has been somewhat controversial
32
what is O2 sat
percent hemoglobin saturation
33
normal O2 sat in healthy person, by age
^94% regardless of age
34
how can O2 sat be misleading in asthma and what to get
compensated asthma, hyperventilation will lead to a decrease in PCO2 of the blood. As a child begins to tire and can no longer maintain adequate ventilation, the PCO2 may normalize and even become elevated despite continued normal oxygenation. Thus, blood gas analysis can be helpful in distinguishing compensated from uncompensated asthma, and in predicting impending respiratory failure.
35
the WORST sign of respiratory distress in peds and others
Paradoxical breathing -diaphragm contracts hard but chest wall muscles not expanding so chest sucks in and belly flares out tachypnea retractions nasal flaring head bobbing (neck strap accessory breathing muscles) grunting (forced expiration against closed glottis... to keep airways open with positive pressure
36
tachypnea vs hyperpnea vs hypopnea
``` rapid rate deep breathing (inc tidal volume) shallow breathing (dec tidal volume) ```
37
when should oxygen be withheld for severe hypoxemia
NEVER Although some patients with chronic hypercarbia (sometimes referred to as "CO2 retainers") depend on their hypoxemia for their respiratory drive, oxygen should never be withheld in cases of severe hypoxemia. Rather, these patients should be MONITORED CLOSELY and given ONLY AS MUCH OXYGEN AS THEY NEED to MAINTAIN A REASONABLE SATIRATION. Endotracheal intubation should be reserved for patients in whom respiratory failure is imminent or loss of the airway is anticipated.
38
4 common 3 less common causes of wheezing in infants and toddlers
viral bronchiolitis asthma foreign body aspiration GER - tracheomalacia - extrinsic compression (vascular ring or sling, or other anatomic airway lesion) - cystic fibrosis
39
5 questions to ask wheezing infant or toddler
timing of wheeze assoc with food change with position or activity other exacerbating factors has it happened in past, if so, did it respond to bronchodilators or steroids
40
5 common causes of cough in toddlers and infants
Viral upper respiratory tract illnesses Pneumonia Post-nasal drip due to allergies and/or sinusitis Foreign body aspiration GE reflux
41
dry cough vs wet/junky cough in infant / toddler
dry cough is typical of CHRONIC ASTHMA whereas a wet cough suggests the presence of SECRETIONS in the airway, whether due to a viral infection, post-nasal drip, gastroesophageal reflux or bronchiectatic disease such as cystic fibrosis.
42
TF wheeze is always expiratory and stridor is always inspiratory
f generally yes, but not always... both can be heard anytime in respiratory cycle
43
triphasic course of pertussis
initial catarrhal stage lasts 1-2 weeks and is characterized by upper respiratory tract infection symptoms. paroxysmal stage that follows lasts 4-6 weeks and is characterized by repetitive, forceful coughing episodes followed by massive inspiratory effort, which results in the characteristic "whoop." Infants generally do not develop a "whoop" due to relative weakness of their inspiratory effort. The paroxysms of cough gradually decrease in frequency and severity as the convalescent stage is entered. Episodic cough may persist for months.
44
acellular pertussis vaccine efficacy and longevity
even with full immunization, vaccine efficacy is only 70-90%. Additionally, protection from the vaccine wanes with time such that many adolescents are unprotected from pertussis unless reimmunized
45
rare causes of epiglottitis now that Hib vaccine is a thing
staphylococcal or streptococcal organisms
46
TF | absence of fever lowers the likelihood of community-acquired pneumonia but does not eliminate it entirely.
T
47
stridor is due to... | and occurs in which phase of respiratory cycle...
Due to airway narrowing above the thoracic inlet. Usually heard with inspiration, but can be biphasic if obstruction is severe
48
wheezing is due to... and occurs in which phase of respiratory cycle... diffuse or focal... polyphonic vs monophonic...
Typically due to airway narrowing below the thoracic inlet. With mild airway obstruction, wheezing is usually heard only in expiration. With increasing obstruction, wheezing may become biphasic and may even disappear altogether when obstruction is severe Although typically diffuse, focal wheeze may be heard in some settings such as mucus plugging. Polyphonic wheeze is characterized by multiple pitches and is typical of asthma; monophonic wheeze is characterized by only a single pitch and is typical of focal airway obstruction.
49
ronchi what do they sound like what phase of respiratory cycle what are they due to
Coarse, low-pitched rattling sounds heard best in expiration. Thought to be due to secretions and narrowing of airways.
50
crackles cause coarse vs fine
Finer breath sounds heard on inspiration. Associated with either fluid in the alveoli or with opening and closing of stiff alveoli (as in interstitial disease). Sometimes described as either coarse or fine. (COARSE crackles are usually thought to be associated with PURULENTsecretions in the alveoli as with pneumonia; FINE crackles are often associated with pulmonary EDEMA or ILD interstitial lung disease.
51
bronchial breath sounds describe cause
Lower in pitch and more hollow-sounding than normal breath sounds. Caused by air moving through areas of consolidated lung.
52
most suggestive physical exam finding for airway foreign body
Significant asymmetry of breath sounds
53
TF | cough, tachypnea, retractions, and absence of fever all support a diagnosis of an asthma exacerbation
T
54
TF | Cough, tachypnea, and mild retractions are typical features of bronchiolitis
T
55
TF | asymmetric breath sounds essentially rules out viral URI (I) as the sole process.
T
56
imaging to get if suspect airway foreign body in kid
pa lat chest biilateral decubitus (each lung deflates when on down-side unless hyperinflated by obstruction) or inspiratory/expiratory chest films (asymmetric deflation with expiration.. but more subtle than bilateral decubitus) chest fluoroscopy - no need to hold breath, can get dynamic evalutaiton bronchoscopy down the line here
57
rigid vs flexible bronchoscopy
rigid bronchoscope is a straight metal tube that can only be inserted through the mouth. It allows one to examine the upper and large airways. Because they can accommodate forceps, rigid bronchoscopes are often used for performing transbronchial biopsies and for removing foreign bodies. Flexible bronchoscopes can be inserted through either the nose or the mouth, and can be used to visualize more distal airways than can be seen with rigid scopes. Because they are smaller than rigid bronchoscopes, flexible scopes used in young children often cannot accommodate forceps. All but the very smallest scopes include a suction port and can be used to collect lavage specimens.
58

69
viral vs bacterial pna presentation in peds
viral prodrome of URTI including cough and rhinorrhea. The cough frequently progresses, and accompanied by fever, tachypnea, crackles bacterial present abruptly or preceded by a viral prodrome. Presentation varies, depending on the age and etiology, but typically fever, cough, and signs of respiratory distress (dyspnea, tachypnea, retractions, etc.), crackles or decreased breath sounds
70
radiographic findings | viral vs bacterial pna
viral variable but most characteristic diffuse or patchy interstitial infiltrates, hyperinflation, small pleural effusions bacterial most typicallly lobar or segmental consolidation and air bronchograms

How is pulmonary fluid eliminated from lungs at birth What happens if it is not removed Aka
Uterine contractions force out Pulmonary lymphatics absorb Transient tachypnea of the newborn Aka Persistent postnatal pulmonary edema ``` Aka 160-180 hr and 60-80 rr of first hour Fail to normalize to 120-160 and 40-60 in second hour (Rated measured at rest not crying) ```
101
Persistent pulmonary hypertension of the newborn What causes it What is it
Persistence of the fetal circulation PPHN can result from several conditions, including meconium aspiration syndrome, diaphragmatic hernia, hypoplastic lungs, and in utero asphyxia. The following findings may indicate that an infant has PPHN: Tachypnea Tachycardia Respiratory distress, with findings such as expiratory grunting and nasal flaring Generalized cyanosis Low oxygen levels, even while receiving 100% oxygen
102
Common Uncommon Respirstory causes of cyanosis in a newborn

103
Common Uncommon Cardiac causes of cyanosis in a newborn
Common Tetralogy of Fallot Transposition of the great arteries (TGA): Defect in which the aorta and pulmonary arteries are transposed, resulting in respiratory distress and severe cyanosis as the ductus arteriosus closes shortly after birth . One risk factor for TGA is being born to a diabetic mother. TGA is often associated with other congenital heart defects, such as a ventricular septal defect, so a murmur may be heard on physical examination. ``` Uncommon Truncus arteriosus Tricuspid atresia Total anomalous pulmonary venous return Pulmonary atresia ```

6 primitive newborn reflexes
Rooting - turns head toward your finger when touch cheek. Sucking - on your finger when you touch roof of mouth. Startle (Moro) - Support head with one hand and buttocks with other. Drop head to 10 cm below. Newborn will flex thighs and knees, fan and then clench fingers, arms first thrown outward then brought together as though embracing Palmar and Plantar Grasps - grasps your finger when you stroke it against the palm or plantar surface Asymmetrical Tonic Neck Response - Turning the head to one side causes gradual extension of arm toward direction of infant's gaze with contralateral arm flexion--like a fencer. Stepping Response - legs make stepping motion when hold him vertically above the table and stroke the dorsum of feet against table edge
