Fetal malformation in maternal toxoplasma and rubella co-infection in Cameroon: a case report.

BACKGROUND: There has been a recent increase in the number of newborns with brain malformations due to congenital infections, but the impact of these diseases remains largely under ascertained in middle-income and low-income countries. This case report presents a fetal anencephaly following maternal toxoplasma and rubella co-infection in a resource-limited setting and the challenges faced by the patient and the health care provider in the management of the condition. CASE PRESENTATION: A 25-year-old black Cameroonian woman of Bakossi origin, gravida3 para1010, presented with a positive rubella and toxoplasma immunoglobulin G serologic test at 21 weeks of pregnancy; she could not benefit from a fetal morphologic ultrasound partly because there was none at the site of her antenatal clinic and because there were accessibility constraints getting to the nearest referral hospital approximately 100 km away. She returned to the hospital in labor pains 14 weeks later and, upon examination, she was observed to be at almost full cervical dilatation and had a stillbirth a few minutes later; a baby boy weighing 1600 g with anencephaly. The devastated parents of the baby were counseled and given psychological support. She was discharged from hospital 3 days later and now benefits from continual follow up as out-patient. She was advised to consult a gynecologist-obstetrician before her next pregnancy. CONCLUSION: Much attention still has to be paid to ameliorate the health care in resource-limited settings where pregnant women generally obtain less than adequate care.

Zoonotic Ljungan virus associated with central nervous system malformations in terminated pregnancy.

BACKGROUND: The Ljungan virus (LV) has been shown to cause central nervous system malformations in laboratory mouse models. The LV has also been associated with intrauterine fetal death in humans. We investigated the presence of LV in a series of human hydrocephaly and anencephaly cases from elective abortions. METHODS: A series of elective abortions owing to hydrocephaly, anencephaly, and similarly aged trisomy 21 elective abortions as controls were examined for LV by immunohistochemistry and real time RT-PCR. A second experiment involved newborn mice exposed to LV. RESULTS: LV was diagnosed in 9 of 10 cases with hydrocephalus and in 1 of 18 trisomy 21 controls by immunohistochemistry. Five of nine cases with anencephaly had a positive PCR result, whereas none of the 12 trisomy 21 available for PCR testing had a positive result. The 47 newborn mice exposed to LV all developed encephalitis, with eight having hydrocephalus. None of the 52 control animals had encephalitis or hydrocephalus. CONCLUSION: The association between LV and both hydrocephaly and anencephaly suggests that LV may be playing an important role in central nervous system malformations in humans.
