A 29 year old women wants to speak to you regarding infections in pregnancy. Her two year old son has sensorineural deafness as a result of infection in her previous pregnancy. What was the most likely infection?
Your Answer: CMV
Explanation:TORCH infections are responsible for perinatal complications. CMV is the most common amongst them. Primary infection often produces no symptoms or mild non-specific flu-like symptoms in the mother. The diagnosis is often made after abnormalities are seen in the foetus on ultrasound scan. The main features seen in an affected foetus are FGR, microcephaly, ventriculomegaly, ascites or hydrops. Some foetuses which are infected may not show any features on ultrasound, but may later be found to have neurological damage such as blindness, deafness or developmental delay. The neonate can also be anaemic and thrombocytopenic, with hepatosplenomegaly, jaundice and a purpureal rash.

You are asked to see a 26 year old patient following her first visit to antenatal clinic. She is 9 weeks pregnant and bloods have shown her to be non-immune to Rubella. She is concerned about congenital rubella syndrome (CRS). What is the most appropriate advice to give?
Your Answer: Advise vaccination after birth regardless of breast feeding status
Explanation:For pregnant women who are screened and rubella antibody is not detected, rubella vaccination after pregnancy should be advised. Vaccination during pregnancy is contraindicated because of a theoretical risk that the vaccine itself could be teratogenic, as it is a live vaccine. No cases of congenital rubella syndrome resulting from vaccination during pregnancy have been reported. However, women who are vaccinated postpartum should be advised to use contraception for three months.

If this is a primary HSV infection (This should be confirmed by lesion swabs to confirm HSV infection and bloods to check no antibody response i.e. evidence previous infection) then C-section is indicated.

Explanation:Obligate anaerobes are a group of bacteria that cannot survive in an oxygen-rich environment. In the body, they are usually found on mucosal membranes such as that of the lower gastrointestinal system, or the vagina. Infection with these organisms is usually suprative and causes abscesses. Examples of gram-negative anaerobes include Bacteroides, Fusobacterium and Prevotella, while gram-positive anaerobes include Actinomyces and Clostridia. Staphylococcus and Streptococcus are both gram-positive facultative anaerobes.
