Q

Clinical definition of failure to thrive

A
  • Note: It is a physical sign, not a final diagnosis
  • Suspected when weight is below the fifth percentile. Usually seen in children under 5 years whose physical growth is significantly less than their peers
  • Divided into organic and non-organic:
    • Organic: Poor growth due to underlying medical condition, such as IBD, renal disease, or congenital heart defect.
    • Non-organic: Poor growth without medical etiology, often related to poverty or child-caregiver interaction

Q

Children with failure to thrive will require ___ as part of intervention

A

Children with failure to thrive will require catch-up calories as part of intervention

You can’t expect them to catch up just by giving them the same amount, they are already behind! They will require ~50-100% excess calories to get where they need to be.

Q

The “picky eater” phenomenon

A
  • Between ages 18 months and 30 months, children often become picky eaters
  • Some will be so picky that they may actually fall off of their weight curve, which can be distressing for families
  • However, this is completely normal and is just a phase. They child has no underlying condition and is not at risk of developmental issues due to this.
  • Counsel parents to avoid force feeding and avoid providing snacks
  • Schedule follow-up

Diagnosis of cerebral palsy in a neonate
. . . **is impossible** The CNS is too immature at this point to tease these things out.
26
Diagnosis of cerebral palsy
* Head imaging by **ultrasound** or **MRI** * May reveal **periventricular leukomalacia, atrophy,** or **focal infarcts** * Beyond infancy, CP should be suspected whenever a child fails to meet an anticipated developmental milestone * ex, **retention of primitive reflexes**: * Moro reflex persisting beyond 6 months * Fencer reflex beyond 6 months
27
Hemiplegia and Diplegia in cerebral palsy
* **Hemiplegia**: Unilateral, **arms** more effected * **Diplegia**: Bilateral, **legs** more effected * Note: Remember your neuroanatomy! This makes sense. The apical-most region of the brain controls the legs, hence palsy involving legs is more likely to be bilateral. Arms are more lateral and thus topographically farther apart.
28
Motor quotient in cerebral palsy
Used to categorize CP by severity Calculated as **motor age / chronologic age** Where "motor age" is age at which their motor functionality would be developmentally appropriate
29
Signs and symptoms of CF
* Recurrent pulmonary infection * **Nasal polyps** * Reactive airways * **Clubbing** * Abdominal distension * **Rectal prolapse** * **Subcutaneous fat and muscle tissue deficiency** * Frequent **steatorrhea** (which may then predispose to **obstruction, volvulus, intussusception** and ischemia)
30
What is the correct way to diagnose CF?
**Sweat chloride test** If the results are equivocal or there are doubts in the results, THEN genetic testing may be utilized
31
How do we screen for CF?
* All infants in most states are screened with a blood test detecting **immunoreactive trypsinogen (IRT)**, a pancreatic enzyme **elevated in newborns with CF** * If the initial test is positive, it is repeated or DNA testing is performed * **DNA testing is diagnostic** * **Two positive IRT tests is only a positive screen** and warrants **referral for diagnostic DNA testing or sweat chloride test**
32
Pseudotumor cerebri
* aka idiopathic intracranial hypertension * **Nausea, positional headache, bulging optic disks,** **bulging anterior fontanelle, pulsatile tinnitus** * **_Cushing's triad:_** High systolic blood pressure, bradycardia, bradypnea * Etiologies: * **Vitamin A toxicity** * **Tetracyclines** * **OCPs** * **Corticosteroid withdrawal** * among others * Treatment: **IV mannitol, acetazolomide**
33
The Great Immitator
* Acute lymphoblastic leukemia * May mimick MANY diseases * **Peak incidence of 4 years of age** * Symptoms: * **Hepatosplenomegaly** * **Joint pain** * **Fever** * **Petechiae** * **Malaise** * **Anorexia** * **Bruising/bleeding** * **_Almost HALF of those with ALL have \<10,000 leukocytes_** * Definitive diagnosis requires **bone marrow biopsy**
34
Therapy for ALL
* **Induction:** Prednisone, vincristine, asparaginase * **Consolidation:** repeat above * **Maintenance therapy:** methotrexate, 6-mercaptopurine, vinrcistine, and prednisone for 2-3 years * Therapy is discontinued for those who remain in remission for 2-3 years
35
Beta agonists are great for asthma in general, but they don't help at all with. . .
. . . **the late phase response of an asthma attack**
36
Most useful agents for the *acute* management of asthma
* SABAs * Anticholinergics * IV Magnesium sulfate * Oral corticosteroids
37
Timing of a late phase response in asthma
2-4 hours after initial wheezing episode Usually more severe and less amenable to albuterol
38
\_\_\_ is among the first steps in assessing growth failure of any etiology
**Bone age** is among the first steps in assessing growth failure of any etiology
39
Diagnostic test for GH deficiency
* Preliminary or screening test: * Should always include IGF-1. . . . AND IGFBP-3 * **You should never order an IGF-1 without an IGFBP-3** * Diagnostic test: * **GH challenge** and interpretation of results by a pediatric endocrinologist
40
Most common cause of death for infants between 1 week and 1 year of age
SIDS
41
Investigation of an unexpected infant death includes thorough history, autopsy, and \_\_\_
Investigation of an unexpected infant death includes thorough history, autopsy, and **death scene investigation** This serves a few purposes. One, it can help identify more occult causes of death such as CO poisoning and can **reduce the risk of recurrence for infantile death**. Second, it is legally required to investigate for **infanticide.**
42
The three benign murmurs heard specifically in childhood
* **Murmur of peripheral pulmonic stenosis:** Systolic mitral-area murmur that radiates to both axillae * **Venous hum murmur:** Hum in the neck or clavicle that disappears with neck flexion * **Still's vibratory murmur:**"Musical" high-pitched murmur heard at LUSB when supine
43
Illness script for juvenile rheumatoid arthritis
* **Daily high-spiking fevers** * **Characteristic rash** * **Generalized lymphadenopathy** * **Organomegaly** * **Anterior uveitis** * **Joint swelling,** especially **phalanges** * **Hematologic changes** (leukocytosis, thrombocytosis, anemia) * Unfortunately, there are no diagnostic tests for JRA! Diagnosis is based upon clinical criteria and exclusion of other diagnoses.
44
Workup and treatment for JRA
* Workup: * **CBC** * ESR and CRP * ANA * RF * **Blood cultures** * **Synovial joint aspiration** (rule out septic etiology) * **Slit lamp exam** (to assess for anterior uveitis, often done periodically once diagnosis is established) * Treatment: * **NSAIDs, steroids, methotrexate, immunosuppressants**
45
Things to know about feeding babies goat's milk
1. It has **little or no B12, iron, or folate**, so they will need supplementation of *at least* these three things, probably more 2. It has a high risk of **Brucellosis** -- therefore it should only be pasteurized and you should have a high clinical suspicion for this if infants display signs of infection
46
"Home renovation" should raise an alarm for. . .
. . . **lead toxicity**
47
How to intrepret the blood lead level
While definitely useful, it is not perfect Significant quantities of lead may be stored within tissues, and so the BLL is not entirely sensitive. Consistent history, labs, signs and symptoms should warrant therapy even if BLL is not at the threshold level for diagnosis.
48
Therapy for lead toxicity
Chelation with either **intramuscular calcium EDTA**, **oral DMSA**, or (if an inpatient) **IV 2-3-dimercaptopropanol (2,3-DMP) aka British anti-Lewisite (BAL)**
49
Recurrent, painless gross hematuria in a child
IgA nephropathy Will usually occur during or very shortly following a respiratory infection
50
Presentation and management of appendicitis
* Presents with **periumbilical pain** which eventually migrates to **McBurney's point**, along w/ **nausea/vomiting, anorexia, fever, and diarrhea** * **Leukocytosis with left-shift and sterile pyuria** may be present just due to the extent of the inflammatory response induced by appendicitis * Management: If suspected, **stat abdominal CT or ultrasound**. Surgical management should be prompt following diagnosis to prevent perforation.
51
Dysfunctional uterine bleeding
* Excessive uterine bleeding that may occur with the regular cycle or between cycles * Effectively idiopathic and is a diagnosis of exclusion * More common in younger women * After verifying that the patient is not pregnant and excluding other possibilities, next steps are stratified by hemoglobin: * **\>12 mg/dL** is considered mild and **iron supplementation and followup** are sufficient * **9-12 mg/dL** is considered moderate, and treatment is with **iron supplementation and OCP** * **\<9 mg/dL** is considered severe, and may need **hospitalization or transfusion** along with **intravenous estrogen** and **high dose OCP** until bleeding stops. OCP is continued until 3-6 months after discharge, then patient may be trialed off of it. * There is a theoretical risk of thrombosis here, but since the timecourse of this therapy is so short and patients are so young there has actually never been a reported episode
52
Simple febrile seizures
* An entity that is unique to children **ages 6 months to 6 years** * Diagnosis that may be _**made *only after* considering CNS infection**_ as the cause. CNS infection should be suspected if: * **Meningitis signs are present OR child is unable to provide feedback** * **Neurologic exam is abnormal following seizure** * **Seizure occured several days into illness** * **Child is \< 1 year of age** * Typically **generalized tonic-clonic seizures** with no focal signs * There is often a **family history** of febrile seizures * Diagnosis: Rule out other etiologies. EEG and brain imaging unnecessary unless there are focal findings, recurrence, or prolonged seizures (1 episode \> 15 min, multiple episodes together \> 30 minutes). LP is not routine except as above. * Treatment: Acutely, **lorazepam** or **diazepam** may be used to **break a seizure lasting \> 5 minutes** (with careful monitoring of respirations). **If refractory, fosphenytoin** may be used instead. Manage the fever, put on seizure precautions now and whenever there is another fever. Educate the parents. **Prognosis is quite good** and typically without neurologic sequellae.
53
Simple vs complex febrile seizures
* **Simple:** * \< 15 minute episodes without focal or lateralizing signs, sequellae, or recurrence * If more than one seizure in a brief period, then the whole episode should last \< 30 minutes * Postictal state may be present for a time, but there should be no lingering deficits * **Complex:** * Lasting longer than 15 minutes (or 30 minutes if multiple) * Focal or lateralizing signs (not primary generalized tonic clonic seizure) * Neurologic sequellae * Recurrence * May require LP or imaging, usually not EEG.
54
Duschene Muscular Dystrophy
* Characterized by progressive **loss of balance, frequent falling**, **difficulty climbing stairs**, **waddling gate,** and **proximal muscle weakness**. Typically appears before age 5. * **Pseudohypertrophy** due to muscle inflammation is classical on exam * **Gower's sign** when going from sitting to standing, shown below * The most common hereitable neuromuscular degenerative disease * Complications: * **Cardiomyopathy** * **Nonprogressive intellectual disability** * **Often wheelchair bound by age 10-12** * **Cause of death is usually respiratory failure** * Diagnosis: **DNA blood analysis** usually works. When it is negative of equivocal, **muscle biopsy** and staining for dystrophin makes the diagnosis. * Treatment consists primarily of orthopedic intervention and physical therapy. There is no cure. **Early cardiomyopathy** may be responsive to **digoxin.**
55
Differential for Duschene's muscular dystrophy
**Becker's muscular dystrophy:** Similar to DMD, but later onset (age 5-15) and more mild course. **Myotonic dystrophy:** Myotonia (impaired relaxation) is hallmark sign. Other features include V-shaped upper lip, thin cheeks, high arched palate, and temporal wasting.
56
If a neonate displays signs of muscular dystrophy and a family history of apparent muscular dystrophy is present, the diagnosis is highly likely to be. . .
. . . **myotonic dystrophy** Duschene's and Becker's take time to develop, only myotonic typically occurs from birth. When it does, it can be very severe and require neonatal ventilatory support.
57
Inheritance of DMD, BMD, and myotonic dystrophy
DMD: X-linked recessive BMD: X-linked recessive Myotonic: Autosomal dominant
58
Therapy for eczema
* **Mild:** emolients and topical low-potency steroids * **Moderate:** emolients, topical higher potency steroids * **Severe:** emolients, topical and potentially oral higher potency steroids, topical calcineurin inhibitors * Oral antihistamines may be helpful at any level of severity to reduce tiching. If lack of sleep due to pruritis is a problem, 1st generation antihistamines are preferred. * Superinfection with staph or strep is treated with 1st generation cephalosporines. Superinfection with herpes is treated with acyclovir.
59
Pityriasis rosea
* Salmon-colored, scaly, itchy rash that spreads to cover the trunk and extremities * **"Herald patch"** preceding dissemination is characteristic and often annular, while other patches are continuous * Treatment is with antihistamines, antipruritic lotions and creams, low-dose topical corticosteroids, and phototherapy * Lasts up to 6 weeks, then resolves
60
Seborrheic dermatitis
* Common in infancy and in adolescence * Chronic, symmetrical eruption characterized by overproduction of sebum * Affects the scalp, forehead, auditory meatus, cheeks, eyebrows, nasolabial folds * Treat by softening scales with **mineral oil** (avoiding scrubbing), and **daily shampooing** with a mild shampoo. **Low to medium potency topical corticosteroids** or **ketoconazole shampoo** are also helpful.
61
Wiskott-Aldrich triad
* **Immunodeficiency** * **Thrombocytopenia** * **Atopy**
62
Neuroblastoma syndrome, diagnosis, and treatment
* Neuroblastomas are tumors derived from primitive neuroendocrine tissue * Commonly occur in the **very young, \< age 10**, and especially in **infants** * Most commonly occur in **abdomen** from **adrenals, are irregular, and cross the midline** * May occur in **thorax** and cause **spinal compression** or **respiratory distress and wheezing** * May occur in **cervical region** and cause **Horner's syndrome** * Associated with **proptosis, perioral bluish discoloration, bone pain, pancytopenia,** and **generalized lymphadenopathy** -- all due to the presence of **metastatic disease** * Paraneoplastic syndrome: **Opsoclonus-myoclonus syndrome** * Diagnosis: Staging with CT and MRI, lab studies showing elevated vanillylmandelic acid and homovanillic acid are observed in most cases * Treatment: **Surgical excision** of tumor **following chemotherapy and/or radiotherapy** to decrease tumor size. Cure rates are \>90%, with infants generally having the best prognosis
63
Wilm's tumor
* Kidney tumor of the very young associated with heritable mutations (WT1) * Associated with **hematuria, hypertension**, and a **localized abdominal mass that usually does _not_ cross the midline**
64
Mesenteric lymphadenitis
Describes irritation of the mesentery and mesenteric lymphadenopathy in the context of viremia, often from an established upper respiratory infection. Clinical picture is usually URI symptoms + diarrhea + abdominal tenderness
65
Opsoclonus-myoclonus syndrome
Paraneoplastic syndrome associated with **neuroblastomas, trophoblastic tumors,** and some others Due to an **autoantibody against neuronal elements** Characterized by chaotic eye movements and myoclonic jerks ("**dancing eyes, dancing feet**")
66
Malrotation with volvulus
* Occurs when intestinal rotation is incomplete during fetal development * Resultant volvulus may happen any time from neonatal period to adulthood, but is most common in infants * Radiographic signs: **Ligament of Treitz on R side, malposition of colon** * When volvulus is present: **Bird's beak duodenum** or **corkscrew duodenum** * Presentation: **Bilious vomiting, abdominal distension, bright red blood per rectum, lethary, colicky abdominal pain**. May progress to **peritonitis, acidosis, and sepsis** if bowel becomes **necrotic.** * **Treatment of acute volvulus:** fluids, correction of electrolyte abnormalities, NG tube to aid in GI decompression, parenteral antibiotics, emergent exploratory laporotomy. * **Treatment of incidentally discovered malrotation:** Requires nonemergent surgical intervention, as frequency and morbidity of volvulus are high.
67
Intussusception
* Classical fatures include **fever, intermittent colicky abdominal pain, currant jelly stools,** and a **"sausage-like" abdominal mass** * Incidence is higher in infants \> 1 year of age * Diagnosis is made with **air contrast enema** * Requires emergent surgical management to save intestinal tissue.
68
Pyloric stenosis
* Classical features: **projectile non-bilious vomiting, olive-shaped abdominal mass** (the hypertrophied pyloric sphincter), and **hypochloremic metabolic alkalosis** * Classically occurs in infants that are a few weeks to months old (the pylorus has hypertrophied since birth and is only now becoming symptomatic) * Diagnosis is with abdominal and chest radiograph * Treatment is surgical
69
Side effects of oral isotretinoin (apart from its teratogenicity)
* Cheilitis * Conjunctavitis * Hyperlipidemia * Blood dyscrasias * Elevated liver enzymes * Photosensitivity
70
Tetracycline, taken orally for acne or infection, should be taken. . .

71
Oral antibiotics may decrease the effectiveness of \_\_\_\_
Oral antibiotics may decrease the effectiveness of **oral contraceptive pills** So, any patient taking an oral antibiotic for any indication who uses OCPs for contraception should also use a **second backup form of contraception**
