Q

pediatric UTI: important history and PE clues

A

Previous UTI or frequent undiagnosed febrile illnesses

Family Hx: UTI, urologic abnormalities

Elevated BP and poor growth - suggest renal insufficiency

Enlarged bladder or kidney(s) - suggest an obstructive uropathy

Bladder/CVA tenderness

External genitalia exam: vulvovaginitis, pinworms, sexual abuse, trauma, STI

Lower back exam → sacral dimples, tufts of hair

50
Q

all infants < 2mo

toxic appearing kids

immuno-compromised

unable to tolerate oral meds (vomit)

concern for F/U

not improving after started tx (outpatient)

51

  • all girl w/ recurrent UTI
  • all boys w/ UTI
  • signs of poor growth, hx of urological abnormalities, FH renal dz
54
Q

urinary tract obstruction - typical presentation

A

febrile UTI
hydronephrosis

later in life: renal insufficiency

55
Q

urinary tract obstruction - evaluation

A

renal U/S: right after UTI confirmed w/ c/s

VCUG: sensitive for VUR

Creatinine level: high may indicate UPJ

bladder distention (on palpation): may indicate posterior urethral valves

56
Q

primary nocturnal emesis: definition and causes

A

child never achieved nighttime dryness

Hypotheses: CNS maturational delay, functionally small bladder capacity, decreased response to vasopressin, genetic/more common in boys, sleep disorder (e.g. OSA)

57
Q

secondary nocturnal enuresis: definition and Ddx

A

new onset enuresis after nighttime dryness was achieved for a period of time

Ddx: diabetes mellitus/insipidus, UTI, pinworms, sexual abuse, dysfunctional voiding/elimination syndrome and chronic renal insufficiency

58
Q

nocturnal enuresis - management

A

Urinalysis: all children should have this (at minimum)
- R/O serious secondary causes

Overall: assess commitment of family/patient (tx takes several months)

  • Reward charts for dry nights
  • Bladder training to increase capacity
  • Fluid management: 80% of fluids in a.m. and early afternoon, 20% (and no caffeine) after 5pm
  • Bed wetting alarm: most effective, $50, and 12-16 week commitment
  • Alarm clock for timed voiding: less expensive option
  • DDAVP tablets (vasopressin): highly effective but significant relapse rate after discontinuation
59
Q

dysfunctional voiding - symptoms

A

very common, part of WCC

Sxs: urgency, accidents, and holding maneuvers (most parents do not recognize until asked)
- ask about “potty dance” (post potty-training) and need to go “right away” or will have accident

Later: develop hesitancy, dribbling and straining (lose typical neurologic/anatomical components of micturition)

Highly associated with constipation (30-88%), development of UTI, acquired VUR, and hx of ADHD

60
Q

dysfunctional voiding - work-up

A

Urinalysis: look for infection and proteinuria (evidence of renal damage from constant back-pressure)
- proteinuria: first am urine is best; if positive, follow w/ serum creatinine (renal fx)

Urine culture/screen
Renal US: needed if obstruction is suspected

61
Q

dysfunctional voiding - management

A

Behavior modification (timed voids q 2-3 hrs): wear a timer

Tx of constipation

Urinate prior to urgency

No straining, complete bladder emptying

Avoid caffeine & bubble baths (due to their risk of UTI)

Reward chart for adherence

Note: urology referral may be needed

62
Q

dysfunctional voiding - Ddx

A
UTI
vesicoureteral reflux (VUR)
vulvovaginits (include pinworms)
adenovirus cystitis (which is hemorrhagic)
STI
urethral strictures
foreign body
sexual abuse
63
Q

cryptorchidism: course, risks, management

A

1 or more of the testes fail to descend into the scrotum; testes not found in scrotum and cannot be manipulated into scrotum by age 6m

course: many descend on own, may need orchiopexy

Risks:

  • ay be indicative of genetic syndrome (examine for dysmorphisms)
  • testicles are at higher risk of cancer; affixing in scrotum allows for frequent pt self-exams

Management:

  • 1st 6 moths: watchful waiting
  • After 6 months: US to determine location, possible orchiopexy
64
Q

retractile testes: course, risks, management

A

testicle may move back and forth between scrotum and groin; common

Course: placing child cross-legged & sitting often allows the testicle to relax into the scrotum

Risks: testicle may be on a short spermatic cord
• Increased stature may result in a testicle that resides in the inguinal canal

Management:

  • noted in the patient’s chronic problem list
  • parents told that son needs exam at his pubertal growth spurt to assess testicular location (in case on short spermatic cord)
65
Q

hydrocele: clinical presentation

A

common, large, sometimes unilateral, swelling to scrotum

- red glow of fluid w/ dark testes on transillumination

66
Q

hydrocele: management

A

Resolve spontaneously by 6 months of age

If not resolved by age 1y, refer to urology

67
Q

A

infected glans and foreskin of penis (circumcised); associated with poor hygiene or aggressive cleaning with soap

Signs and symptoms:

69
Q

fever: causes in developed countries (with vaccines)

A

viral infections: 90%

bacteremia: 1% for vaccinated; 5% for unvaccinated
- meningits, UTI, pneumonia, osteomyelitis, septic joint, cellulitis

other causes:

  • Kawasaki’s
  • Cancer
  • rheumatic dz: JIA, SLE
70
Q

most common serious bacterial infection: relative risk

A

meningitis: most serious (0.5%)
- most serious; N. Meningitides is concern (WBC poor predictor - sneaky

UTI: 2-5% (E. coli most common)
- 1 of 2 most common

Pneumonia: 5%

  • only order CXR in presents of clinical signs
  • 1 of 2 most common

Septic joint, osteomyelitis, cellulitis

71
Q

viral causes of fever that are a concern in infants

A

Varicella and Herpes: risk of disseminated dz
RSV: risk of respiratory compromise (also simultaneous UTI)
Influenza: risk of secondary infections and respiratory compromise

72
Q

pneumonia - clinical signs of LRI

A

tachypnea, cough, inc. WOB (runny nose, abnormal breath sounds)

73
Q

what is common with RSV

A

To also have a UTI causes by bacteria (7%)!

74
Q

fever in child 0-36 months (< 3yrs): Ddx

A

Viral: RSV, croup, varicella, cocksackie, herpetic gingivostomatitis, AOM (low prevalence <3mo)

Bacteremia (2-3%, <0.5% S.pneumoniae)
- Meningitis (0.5%), UTI (2-5+%), pneumonia (5%), septic joint, osteomyelitis, cellulitis

Kawasaki’s

Cancer,

Rheumatological dz (JIA, lupus)

75
Q

fever in child > 3 yrs: Ddx

A

Viral: AOM, RSV, varicella, cocksackie, herpetic gingivostomatitis, croup (less likely)

Bacteremia (2-3%, <0.5% S.pneumoniae)
- Meningitis (0.5%), UTI (2-5+%), pneumonia (5%), septic joint, osteomyelitis, cellulitis

Kawasaki’s

Cancer, Rheumatological dz (JIA, lupus)

76
Q

likelihood of various illnesses being fever source

A

Bacterial gastroenteritis: if hx of diarrhea (esp. w/ blood or mucous) consider this possibility

Rapid influenza test: false positives are frequent, (+) results only helpful if flu season

RSV if cough and inc. WOB (in season): 1.1-7% risk of concomitant SBI (UTI)

Croup, varicella, obvious cocksackie (hand, foot, mouth) or herpetic gingivostomatitis (HSV on gums): unlikely to have concomitant SBI
- feel comfortable that these dx explain the fever

Otitis media: low prevalence in children < 3m/o
- be sure PE matches dx for AOM → many children wrongly dx w/ AOM (missing a SBI)

77
Q

causes of prolonged fever

- viral causes typically last 3-5 days

A

SBI that has not been located: do a CRP / ESR

CMV, EBV: common culprits of prolonged fever (important tests in primary care)

Tuberculosis
Lymphoma and Leukemia
Juvenile Idiopathic Arthritis
Endocarditis
Malaria
Hyperthyroidism
Kawasaki’s disease
 - FWS may be only sx in infants
78
Q

what MUST you do before giving empiric ABX for child with fever W/O source

A

get a lumbar puncture - once begin ABX, results will not be accurate and may be difficult to know what bacteria is present and how to treat

79
Q

what additional test many be helpful to determine low v. high risk in infants w fever W/O source: age 29 to 60/90 days

A

rapid viral testing (nasal wash with PCR) to look for RSV, flu, etc.
- may help to avoid invasive testing (lumbar puncture)

80
Q

low risk criteria for bacteremia (used in children >29 days old)

Inflammatory markers (CRP and  PCT)

Note: also consider rapid nasal wash viral testing

best lab tet predictor of serious bacterial infection (SBI)

A

Inflammatory markers (CRP and PCT (procalcitonin)): if both are positive, best predictor of SBI (compared to WBC or band count)

82
Q

ill child - clinical signs

A
lethargy
poor perfusion (general color, capillary refill, turgor, blood pressure)
very slow or very fast breathing
cyanosis
abnormal cry

Young children who are hypothermic (<37C), esp. neonates who may not mount febrile response

83
