Widespread use of napthol-containing compounds and frequent contamination of foods by aflatoxins occurs in Nigeria. Napthols cause haemolysis and aflatoxins are hepatotoxic. A study was carried out to determine the extent of fetal exposure to these compounds and their influence on birthweight. Cord blood samples were collected at delivery from 625 babies and their sera were analysed for aflatoxins and naphthols. Mothers' histories and babies' weights were recorded. Naphthols were detected in 6.9% and aflatoxins in 14.6% of serum samples. No correlation was found between the presence of either compound and birthweight. Reported exposure to naphthalene-containing compounds was not related to detection of serum naphthol. Results show considerable fetal exposure to these potentially toxic compounds in Ibadan, Nigeria.

Pulmonary sequestration is a rare pulmonary malformation, typically characterized by asymptomatic presentation or recurrent pulmonary infections, with chest pain and hemothorax being exceedingly rare occurrences. The rupture and hemorrhage of maternal pulmonary sequestration during pregnancy pose a life-threatening condition that is challenging to diagnose. We present a case of a 37-year-old pregnant woman in her third trimester who presented with acute progressive hemothorax, a complication arising from maternal pulmonary sequestration.

Background: Toxoplasma gondii is a ubiquitous parasite that can cause significant complications when it infects pregnant women and immunocompromised patients. These complications include miscarriage, fetal abnormalities, and fatal cerebral toxoplasmosis. Despite its significance, the true burden of toxoplasmosis in Indonesia remains underexplored.

Neonatal health is dependent on early risk stratification, diagnosis, and timely management of potentially devastating conditions, particularly in the setting of prematurity. Many of these conditions are poorly predicted in real-time by clinical data and current diagnostics. Umbilical cord blood may represent a novel source of molecular signatures that provides a window into the state of the fetus at birth.
