Study Notes
Congenital Toxoplasmosis
- Preventive measures include avoiding cat litter and undercooked food.
- Mothers often show no illness symptoms; treatment usually focuses on postnatal infants.
- Confirmation of infection is essential to rule out other causes.
- Treatment regimen involves Pyrimethamine and Sulfadiazine, with Leucovorin for those on Pyrimethamine.
ParvoVirus B19
- Associated congenital effects include various developmental disorders.
Varicella Zoster Virus (Chicken Pox)
- Highly contagious with a 90% attack rate in unvaccinated adults.
- Seasonal outbreaks typically occur in late winter and early spring.
- Symptoms develop within 14 days post-exposure and include fever, malaise, and pruritic vesicles.
- In healthy children, the infection is usually self-limiting with symptomatic treatment.
- High-risk groups can benefit from antiviral treatment, although complications are rare.
- A live virus vaccine has been available since 1995, which is contraindicated during pregnancy.
Congenital Varicella
- Most concerning if the mother is non-immune and infected during the 1st or 2nd trimester.
- Vaccination is not permitted during pregnancy.
Rubella (German Measles)
- A major cause of childhood exanthems, transmitted via respiratory droplets.
- Symptoms include fever, sore throat, headache, pink eye, and prominent lymphadenopathy.
- The rash typically descends from the face down to the body.
- Rubella vaccination is part of the MMR vaccine series.
Congenital Rubella Syndrome
- Diagnosed through prenatal serology; IgG positive indicates immunity.
- Maternal infection during the first trimester poses risks of severe congenital defects.
- Classic triad of congenital rubella syndrome includes hearing impairment, cataracts, and heart defects, particularly patent ductus arteriosus.
Cytomegalovirus (CMV) in Pregnancy
- CMV can be transmitted via bodily fluids; infections are mild in healthy adults.
- Initial pregnancy infection risks fetal transmission; congenital infection can lead to significant birth defects.
- Perinatal infection can be asymptomatic yet still pose risks.
- Blood tests may reveal atypical lymphocytes indicative of infection.
Congenital CMV Effects on Newborns
- Potential outcomes include deafness, chorioretinitis, seizures, microcephaly, and a "blueberry muffin" rash.
- No antiviral treatment has shown to reduce fetal transmission.
Herpes Simplex Virus
- Mostly transmitted during the perinatal period; active outbreaks require C-section delivery.
- Symptoms manifest within 10-21 days after birth, including fever and sepsis-like presentations.
- High-dose IV Acyclovir is the primary treatment.
Zika Virus
- Mosquito-borne flavivirus with potential for sexual transmission.
- Incubation period spans 2-14 days; about 20% of patients exhibit clinical signs.
- Mild symptoms include low-grade fever, rash, arthralgia, and conjunctivitis.
- Infection in pregnancy can result in microcephaly in infants; no effective therapy available.
Group B Streptococcus (GBS)
- Gram-positive bacterium commonly found in gastrointestinal and genital tracts.
- Primary cause of infection in newborns; transmission can occur during delivery.
- Universal screening has significantly reduced disease incidence.
- Early onset occurs from day 0-6; late onset can develop from day 6 to 3 months.
Neonatal Infections
- An infant with a rectal temperature of 100.4°F (38°C) requires a sepsis workup.
- E. coli UTI is the most common bacterial infection, with GBS as the second most common.
- Increased risk of bacterial infections in neonates with a history of viral infections at birth.
Infections in Infants Over 28 Days Old
- A fever greater than 100.4°F (38°C) warrants a thorough investigation with a low threshold for sepsis workup.
Clostridium Botulinum (Botulism)
- Spores found in soil can contaminate food, leading to gastrointestinal ingestion.
- Produces a neurotoxin causing hypotonia and flaccid paralysis; severe symptoms may include respiratory failure.
- Diagnosis involves detection of toxins in stool; prevention includes proper food handling.
TORCH Infections
- Refers to a group of congenital infections, including Toxoplasmosis, other, Rubella, Cytomegalovirus, and Herpes, with significant risk for newborns.
