Q

What is a feeding disorder?

A

Impairment in the process of food transport outside the alimentary system (GI Tract)
Usually an umbrella term encompassing all feeding problems regardless of the etiology severity or even the consequences.
Usually is the result of weakness or incoordination in the hand or arm used to move the food from the plate to the mouth

What is short bowel syndrome?
Malabsorption secondary to resection of small intestine
26
What is a small stomach due to fundoplication?
Child easily feels full
27
What is a congenital diaphragmatic hernia?
A hole in the diaphragm allows abdominal organs to herniate (migrate) into the chest
28
What is hiatal hernia?
Protrusion of the stomach into the mediastinal cavity Through the esophageal hiatus of the diaphragm pushing the lower esophageal sphincter away from the diaphragm (mimics acid reflux–burning sensation, chest pain, trouble in swallowing, and regurgitation of food and liquid)
29
What is increased physiologic stress in breathing?
Negative influence on: suck-swallow-breathe coordination, energy required for feeding Examples: Laryngomalacia, Tracheomalacia (the trachea collapses), Holes in the heart, Aortic stenosis
30
What is penetration?
A foreign objects enters the airway but not beyond the vocal folds (food enters the laryngeal inlet)
31
What is aspiration?
Foreign object enters airway beyond vocal folds (trachea pababa papunta sa lungs)
32
Aspiration happens due to several factors. What are these?
No swallow reflex Delayed swallowing Poor timing and coordination Residue because of poor pharyngeal movement Vocal cords paralysis
33
This is the most common GIT disorder
GERD (Gastroesophageal reflux diseases)
34
Stomach contents reflux proximally because of LES incompetence. Typical symptoms: vomiting and gagging. It is also the most frequent and most pervasive physiological limit.
GERD
35
Factors that contribute to GERD
Respiratory problems (e.g., labored breathing, overinflated lungs) Increase pressure due to coughing Medication for respiratory stress
36
What are the respiratory effects of GERD?
- Larynx irritation (cough and hoarseness) - Micro-aspiration or refluxed contents - Chronic bronchitis and asthma-like symptoms - Apnea
37
What are postural problems?
Respiratory problems due to postural problems (e.g., kyphosis, scoliosis) Decreases the depth of respiratory volume
38
What are respiratory issues due to tone problems?
- Poor basis of respiratory control - Difficulty moving chest muscles - May develop compensatory methods of breathing that provide less respiratory support for feeding
39
What is a tracheostomy tube?
Mechanically restrict upward movement of larynx, increases the chances of aspiration Can lead to desensitization of the larynx which can reduce protective reflexes and can lead to uncoordinated closure
40
True or False. Children with cardiac or respiratory problems will have poor feeding endurance and become short of breath while feeding and poor growth and nutrition
t
41
Mouth may hang open or move up and down excessively when trying to suck.
Exaggerated jaw movement
42
This is related to general jaw instability, would make? It is associated with?
The jaw slip and shift forward or to the side Associated with low postural tone and poor stability of neck and truck Associated with poor control of TMJ
43
What is jaw thrust?
Strong downward movement of jaw when utensil or food is presented to the mouth–different from normal full mouth opening May include sudden shifts forward to the side Can cause TMJ dislocation
44
What is the tonic bite reflex?
When biting surfaces of teeth or gums are touched, the child bites with associated tension–meal times may be challenging, because it is hypertonic. This may be caused due to the hypersensitivity. Bite is not easily released
45
What is jaw clenching? What can it cause?
The jaw is tightly closed involuntarily. Possibly due to: part of primary flexor in the shoulder and neck, oral hypersensitivity, self-stimulating a tonic bite May lead to the shortening of jaw muscles and connective tissue therefore it could lead to limited ROM at the TMJ
46
What is jaw retraction?
Jaw is pulled backward There is difficulty with opening of the mouth fully
47
What is tongue retraction? What does it cause? How is it compensated by some?
Tongue is pulled backward May be due to shoulder girdle retraction–due to limits in postural tone, neck may also be hyperextended with chin tipped up. Leads to a smaller airway Some compensate by pressing tongue against the hard palate
48
What is a low-toned tongue?
acks ability to flatten, thin, and cup Thick and lacks central groove Difficult to present spoon or nipple as it interferes with comfortable placement
49
Rhythmical extension and retraction of tongue but movement during the extension portion goes beyond gum ridge and teeth. Common in children with low tone and respiratory disorders
Exaggerated tongue protrusion
50
Very forceful protrusion of tongue from the mouth. It is arrhythmitic (no sequence) and may cause food to be pushed out. Makes inserting a nipple or spoon difficult. Persistence of infantile swallow pattern during late childhood.
Tongue thrust
51
Low-tone lips may cause what?
Food may fall out of the mouth
52
Low-tone cheeks will
Cause the food to fall into the cheek cavity
53
Lips are pulled forward from lip retraction, action similar to a drawstring closing a laundry bag
Lip pursing
54
What is lip retraction?
Lips are drawn back in a tight horizontal line Difficulty for lips to assist in sucking, removing food from the spoon, etc., May be due to extension and retraction patterns in the neck and shoulder girdle
55
What is velopharyngeal insufficiency?
Soft palate is too short Food can enter the nasal cavity
56
Overall difficulties with tone and movement may contribute to this
Inaccurate timing of palate elevation
57
It reflects the underlying muscle tone (e.g., mouth hangs open due to low muscle tone)
Primary patterns
58
Compensating for underlying issue of tone and instability (e.g., tensing some of the jaw muscles to increase stability for tongue movement)
Compensatory patterns
59
What is hyperreaction?
Unexpectedly strong reaction to a specific sensation Increase in tone and reflex patterns appear to reduce sensory thresholds History of tube feedings may also be a cause
60
What is hyporeaction?
Reduced reaction to specific sensations Can cause severe feeding disorders or indifference toward eating Can also be caused by certain meds ‘Often accompanies lowe postural tone
61
What is sensory defensiveness?
**System perceives a sensation as dangerous** (moves into fight or flight) Cans cause different reactions One or several sensory system may be involved
62
What is sensory overload?
Difficulty modulating amount and type of sensory information consciously processed Some may be overwhelmed and unable to function Some maye be hyperreactive and unable to function Some may be hyperreactive and distractible Some may present with fleeting attention Some may engage in rhythmic behaviors Yung input sa paligid masyadong marami for u to process
63
Bottle-or breast-feeding requires what?
Ability to latch onto the nipple Ability to create negative pressure to suck the milk Ability to let the milk flow an uninterrupted stream to the pharynx
64
When a child has concerns with sucking, there are difficulties with? Which structures?
Jaw, tongue, lips, cheeks or palate will contribute to sucking problems Problems with organization will have an effect as well
65
Biting
Normal jaw control Normal sensory perception of thickness, hardness and size
66
Swallowing requires
Ability to organize the bolus to move toward the back to initiate the swallow reflex Ability to time and coordinate breathing with eating Strong enough muscles to move bolus with eating
67
If you have swallowing problems, you will have difficulties with the following:
Difficulties with jaw (e.g., open-mouth posture), tongue, lips, cheeks, or palate will contribute to swallowing difficulty Problems with sensory awareness and organization will have an effect as well
68
Chewing requires
Keeping the food in the mouth with the lips and cheeks Coordination of jaw and tongue movements
69
The following have the greatest effect on chewing:
Jaw thrust Jaw clenching Tonic bite Tongue retraction Tongue thrust
70
Chewing difficulties with sensory acuity or perception will have which effects?
Some children refuse food with certain textures Some children just swallow solids wholes, without chewing Some children are unaware that some food was left in the mouth
71
Saliva is for
Moistening food Helping break down food with enzyme Protecting teeth from diseases and infection Keeping the mouth wet for smooth articulation
72
Possible causes of sialorrhea (excessive drooling)
Difficulty maintaining posture Airway obstruction → open mouth posture Decreased sensation Reduced ability to concentrate and remember to swallow
73
This is the most common condition to create congenital neurologic dysphagia
Cerebral palsy
74
This is the greater dysfunction in phases with significant voluntary components (oral stage)
Spastic CP
75
What are the common limiting patterns for spastic CP?
- Tongue thrust - Hyperactive or hypoactive gag reflex - Hypersensitivity - Tonic bite reflex - Inadequate function of lip and cheek muscles → poor bolus formation → inhibits distal propulsion of bolus Difficulty coordinating swallowing with breathing
76
Pharyngeal dysfunction is also common with spastic CP. True or False
True. There is difficulty with coordinating swallowing with breathing
77
What is cortical damage?
Manifestations range from no observable swallow activity to poorly coordinated execution of the act of swallowing
78
What are the frequent cortical pathologic conditions?

82
Cortical plasticity may occur over time increasing…
Increasing the utility of the intact, nondominant hemisphere to control swallowing motor functions
83
What are the swallowing deficits in association to hemispheric stroke?
Dry swallow (poor initiation of saliva swallow) Incoordination of the oral (voluntary stage) components of swallowing Delay in initiation of the pharyngeal component of the swallow Increased pharyngeal transit time and reduced pharyngeal constriction and clearing → Aspiration Dysfunction of the pharyngoesophageal segment – cricopharyngeal muscle Poor relaxation of the lower esophageal sphincter
