Placental pathology is a unique area of perinatal pathology whose understanding requires knowledge of normal development, physiology and histopathology as well as foetal and maternal medicine. Request of placental examination has grown exponentially in the recent years, and this has not been paired with histopathologist trained in reporting them.

This course will provide an up-date on placental physiology, current classification, and new insights into the knowledge of placental conditions. 

The course “Up-date on placenta: physiology and new concepts” is designed to paediatric/perinatal and general histopathology trainees as well as consultants. The course  will also be of benefit to obstetricians, both consultants and in training.

  • Dr Mudher Al-Adnani

    I have been a consultant in Paediatric and Perinatal Pathology for 13 years (5 years at Sheffield Children’s Hospital and 8 years at St Thomas’ Hospital). Currently, I am the Paediatric and Perinatal Pathology service lead. My areas of interest are Paediatric/Perinatal autopsies, placental pathology and paediatric GI pathology.

  • Dr Emmanuel Amabebe

    I am a physiologist interested in understanding the mechanistic pathways of infection and inflammation associated preterm birth. I study female genital tract microbiota, dysbiosis, infection and inflammatory responses that trigger the pathway to preterm birth using cervicovaginal fluid and placental tissues. We have identified some cervicovaginal bacterial species, metabolites and cytokines that are associated with preterm birth with clinically useful predictive value. My research is currently focused on the correlation of the mechanistic risk factors of infection/inflammation associated preterm birth across divers racio-ethnic groups in low-middle income countries versus developed countries. I am currently a Postdoctoral Research Associate at the Department of Oncology and Metabolism, University of Sheffield, UK, working on an NIHR Global Health Research project on Preterm Birth Prevention and Management (PRIME).
