Study Notes
Wheezing in Children
- Bronchoscopy is the most effective diagnostic tool for determining the cause of persistent wheezing in a child when bronchodilators are ineffective.
- Exclusive breastfeeding, unlike maternal smoking, early allergen exposure, and parental asthma history, is not a risk factor for recurrent wheezing in children.
- Nebulized hypertonic saline is the first-line treatment for wheezing caused by acute bronchiolitis.
- Monophonic wheeze is a type of wheezing commonly associated with large airway obstruction.
- Foreign body aspiration is a condition likely to lead to wheezing that doesn't improve with bronchodilators, unlike bronchitis, asthma, or RSV infection.
Hematuria
- Glomerular hematuria exhibits dysmorphic red blood cells, distinguishing it from hematuria due to kidney stones, bladder infection, or urethral hematuria.
- Poststreptococcal glomerulonephritis is the most likely diagnosis in a child with hematuria and recent pharyngitis.
- Renal ultrasound is the preferred imaging modality for evaluating a child with hematuria and suspected urinary tract obstruction.
- Urine dipstick test primarily detects hemoglobin or myoglobin, aiding in diagnosing hematuria.
- Dysmorphic red blood cells in urine are highly indicative of hematuria originating from the glomeruli.
Acute Diarrhea
- Secretory diarrhea is characterized by toxins directly stimulating intestinal mucosa secretion.
- Rotavirus is the most prevalent cause of acute diarrhea in children under two years old globally.
- Oral rehydration solution (ORS) is the recommended fluid replacement method for children with mild dehydration due to diarrhea.
- Antibiotics are the appropriate treatment for children with acute bacterial diarrhea manifesting with bloody stools and fever, but only upon confirmation of a bacterial pathogen.
- Antibiotic prophylaxis is not a recommended preventive measure against rotavirus infection.
Chronic Diarrhea
- Celiac disease is most likely to cause chronic diarrhea with fatty stools (steatorrhea) in children.
- The anti-tissue transglutaminase (tTG) antibody test is crucial for confirming a celiac disease diagnosis.
- Lactose-free diet is the appropriate dietary intervention for children with chronic diarrhea due to lactose intolerance.
- Cystic fibrosis is a condition often linked to chronic diarrhea and failure to thrive in children.
- Elevated fecal fat content strongly suggests malabsorption as the underlying cause of chronic diarrhea.
Lymphadenopathy
- Generalized lymphadenopathy is most commonly associated with Epstein-Barr virus (EBV) infection.
- Persistent enlargement of lymph nodes for over 6 weeks is a concerning sign requiring a biopsy.
- Watchful waiting is the typical initial management approach for reactive lymphadenopathy.
- Staphylococcus aureus is the most frequent causative agent in cases of lymphadenopathy due to bacterial infection.
- Fever and night sweats, along with lymphadenopathy, are particularly worrisome signs suggesting malignancy.
