IBCLC Maternal and Infant Pathology 2 — Questions and Answers
Question 1: A breastfeeding mother presents with a red, wedge-shaped area on her breast, fever of 38.5C, and flu-like symptoms. What is the most likely diagnosis?
- Engorgement
- Lactational mastitis (Correct answer)
- Breast abscess
- Inflammatory breast cancer
Correct answer: Lactational mastitis
The combination of a localized red, wedge-shaped area with systemic symptoms is the classic presentation of lactational mastitis.
Lactational mastitis occurs in approximately 10-20% of breastfeeding women. It most commonly occurs in the first 6 weeks postpartum. Risk factors include milk stasis, nipple damage, fatigue, and restrictive clothing. Management includes continued breastfeeding, effective milk removal, anti-inflammatory medications, and antibiotics if symptoms do not improve within 24 hours.
Question 2: An infant is diagnosed with ankyloglossia (tongue-tie). Which assessment tool is commonly used to evaluate its impact on breastfeeding?
- The Apgar score
- The Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) (Correct answer)
- The Edinburgh Postnatal Depression Scale
- The LATCH scoring system alone
Correct answer: The Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF)
The HATLFF specifically evaluates both the appearance and function of the lingual frenulum.
The HATLFF assesses five appearance items and seven function items including lateralization, lift, extension, spread, cupping, peristalsis, and snapback. Each item is scored, with threshold scores indicating whether intervention is needed.
Question 3: A mother with HIV infection in a high-income country asks about breastfeeding. What is the current recommendation?
- Breastfeeding is always recommended regardless of HIV status
- In high-income countries, formula feeding is generally recommended to eliminate the risk of HIV transmission through breast milk (Correct answer)
- Breastfeeding is safe if the mother is on antiretroviral therapy regardless of the setting
- The mother should breastfeed but only for the first month
Correct answer: In high-income countries, formula feeding is generally recommended to eliminate the risk of HIV transmission through breast milk
In high-income countries with access to safe water and affordable formula, avoidance of breastfeeding is generally recommended.
Guidelines vary by setting due to competing risks. In high-income countries, formula feeding is recommended to eliminate the breastfeeding transmission risk. In low-resource settings, WHO recommends breastfeeding with maternal ART because the mortality risk from unsafe formula preparation outweighs the HIV transmission risk.
Question 4: What is the most common cause of neonatal jaundice in the first week, and how should breastfeeding be managed?
- Breast milk jaundice requiring breastfeeding cessation
- Physiological jaundice exacerbated by insufficient breastfeeding; increase breastfeeding frequency (Correct answer)
- Blood group incompatibility requiring formula supplementation
- Liver disease contraindicating breastfeeding
Correct answer: Physiological jaundice exacerbated by insufficient breastfeeding; increase breastfeeding frequency
Early-onset neonatal jaundice is most commonly physiological, often worsened by suboptimal breastfeeding. Increasing breastfeeding frequency is the primary management.
Breastfeeding jaundice results from insufficient caloric intake and reduced stooling, which decreases bilirubin excretion. Bilirubin is excreted primarily through stool. Management focuses on increasing breastfeeding frequency (8-12 times/day) and ensuring effective milk transfer.
Question 5: A mother develops Raynaud's phenomenon of the nipple with severe blanching and pain after breastfeeding. What is the pathophysiology?
- Infection of the nipple causing inflammation
- Vasospasm of the nipple blood vessels in response to cold or compression, causing ischemia and pain (Correct answer)
- Allergic reaction to infant saliva
- Nerve damage from poor latch
Correct answer: Vasospasm of the nipple blood vessels in response to cold or compression, causing ischemia and pain
Raynaud's phenomenon involves vasospasm causing characteristic triphasic color changes (white, blue, red) and significant pain.
The classic presentation includes triphasic color changes: white (vasospasm/ischemia), blue (cyanosis), and red (reperfusion). Management includes warmth application immediately after feeding, avoidance of cold exposure, and nifedipine for refractory cases.
Question 6: An infant with Pierre Robin sequence is having difficulty breastfeeding. What are the primary anatomical features that complicate feeding?
- Cleft lip only
- Micrognathia (small jaw), glossoptosis (posterior displacement of the tongue), and often a U-shaped cleft palate (Correct answer)
- Macroglossia (enlarged tongue)
- Bilateral choanal atresia
Correct answer: Micrognathia (small jaw), glossoptosis (posterior displacement of the tongue), and often a U-shaped cleft palate
Pierre Robin sequence involves a triad of micrognathia, glossoptosis, and frequently a U-shaped cleft palate, all significantly impairing feeding.
These features impair breastfeeding because the infant cannot achieve adequate jaw excursion, the posteriorly displaced tongue cannot cup the breast properly, and the cleft palate prevents creation of negative pressure. Some infants can achieve direct breastfeeding as the mandible grows, typically improving around 3-4 months.
