what is this? how do you manage it?

ankyloglossia - conservative management, only do frenotomy if significant breastfeeding difficulties (use acetaminophen, sucrose or lidocaine for analgia - benzocaine ineffective)
what is this? what are the common bugs that cause this? how do you treat?

Opthalmia neonatorum - conjunctivitis occuring within first 4 weeks of life. gonorrhea < 1%, chlamydia 2-40% of the time.
Tx: erythromycin is not effective against chlamydia and 25% of gonorrhea is resistant - it is NOT recommended. Recommended to culture conjunctival discharge, tx ceftriaxone (if suspect gonorrhea). No routine culture or treatment of chlamydia opthalmia (only if symptomatic!)
what is this? what condition is it associated with? how do you diagnose this condition?

Erythema migrans, clinical sign of lyme disease, presents in 7-14 days (painless, non-pruritic) - may have multiple lesions in early disseminated disease.
Diagnosis: if early localized = clinical diagnosis. If early disseminated/late disease - diagnosed by ELISA screen and confirmatory western blot

syndrome? gene? inheritance?

Achondroplasia, due to mutations at FGFR3. Behaves as autosomal dominant, the clinical manifestation is due to heterozygous achondroplasia (homozygous achondroplasia is usually lethal in the newborn period)
