In 18 patients who presented in less than 2 years with heart disease characterized by arrhythmias (including atrial fibrillation, ventricular arrhythmias and heart block), atypical chest pain, pericarditis and cardiac failure, extensive investigation revealed no cause for the disease except for evidence of toxoplasmic infection. One patient had acute toxoplasmosis; the other 17 patients had chronically increased titers, higher than the expected level in the community and also higher than in a control series of patients with well defined heart disease. Toxoplasmosis is probably a fairly common cause of heart disease in this community. The source of infection appeared to be cats, uncooked meat and congenital infection. Patients received chemotherapy with either pyrimethamine and sulfadiazine or tetracycline. Serious relapse occurrred in three patients and embolic complications in two. Experimental myocarditis occurs when toxoplasmic cysts rupture within the heart; therefore clinical symptoms may occur sporadically during a chronic infection.

Over a thousand women with confirmed rubella infection at different stages of pregnancy were followed up prospectively. Two-thirds of the women were multiparous. Pregnancy continued in 40%, and the infants were followed up after birth both clinically and serologically. The frequency of congenital infection after maternal rubella with a rash was more than 80% during the first 12 weeks of pregnancy, 54% at 13-14 weeks, and 25% at the end of the second trimester. The infection rate then rose again to reach a high figure in the last month. Follow-up was to 2 years of age--the findings in infected children being compared with those in children who had escaped infection. Rubella defects occurred in all infants infected before the 11th week (principally congenital heart disease and deafness) and in 35% of those infected at 13-16 weeks (deafness alone). No defects attributable to rubella were found in 63 children infected after 16 weeks. Continued surveillance of cases of confirmed rubella during pregnancy is recommended as an additional way of monitoring the effect of rubella vaccination.

In 2 infants, a girl and a boy, congenital viral infection was diagnosed in the neonatal period. The prenatal examination (serologic investigation for Toxoplasma gondii, rubella virus, cytomegalovirus, herpes simplex virus and syphilis (TORCHES)) was negative. In both cases prenatal ultrasonography was abnormal and suggested intrauterine infection. The infants were born with typical symptoms of multisystem disease, known as symptomatic congenital cytomegalovirus infection (jaundice, petechiae, hepatosplenomegaly, intrauterine growth retardation, microcephaly and cerebral calcifications) and congenital rubella syndrome (intrauterine growth retardation, congenital heart disease, cataract, hepatosplenomegaly and cerebral calcifications), respectively. Both had severe cerebral damage. To diagnose severe congenital infection in the first trimester of pregnancy in presence of congenital anomalies in utero there are other possible methods than TORCHES investigation, such as polymerase chain reaction and virus culture in amniotic fluid or in foetal blood obtained by cord puncture.

Congenital infections refer to a group of perinatal infections that may have similar clinical presentations, including rash and ocular findings. TORCH is the acronym that covers these infections (toxoplasmosis, other [syphilis], rubella, cytomegalovirus, herpes simplex virus). There are, however, other important causes of intrauterine/perinatal infections, including enteroviruses, varicella zoster virus, Zika virus, and parvovirus B19. Intrauterine and perinatal infections are significant causes of fetal and neonatal mortality and important contributors to childhood morbidity. A high index of suspicion for congenital infections and awareness of the prominent features of the most common congenital infections can help to facilitate early diagnosis, tailor appropriate diagnostic evaluation, and if appropriate, initiate early treatments. In the absence of maternal laboratory results diagnostic of intrauterine infections, congenital infections should be suspected in newborns with certain clinical features or combinations of clinical features, including hydrops fetalis, microcephaly, seizures, cataract, hearing loss, congenital heart disease, hepatosplenomegaly, jaundice, or rash. Primary prevention of maternal infections during pregnancy is the cornerstone of prevention of congenital infection. Available resources should focus on the promotion of public health.

Congenital infections refer to a group of perinatal infections that are caused by pathogens transmitted from mother to child during pregnancy (transplacentally) or delivery (peripartum) which may have similar clinical presentations, including rash and ocular findings. TORCH is the acronym that covers these infections (toxoplasmosis, other [syphilis], rubella, cytomegalovirus, herpes simplex virus). Other important causes of intrauterine/perinatal infection include human immunodeficiency virus, varicella-zoster virus, Treponema pallidum, Zika virus, and parvovirus B19. This overview aims to describe various congenital infections beyond TORCH with a Hong Kong perspective. Intrauterine and perinatal infections are a major cause of in utero death and neonatal mortality, and an important contributor to childhood morbidity. A high index of suspicion for congenital infections and awareness of the prominent features of the most common congenital infections can help to facilitate early diagnosis, tailor appropriate diagnostic evaluation, and initiate appropriate early treatment. Intrauterine infections should be suspected in newborns with clinical features including microcephaly, seizures, cataract, hearing loss, congenital heart disease, hepatosplenomegaly, small for gestational age, and/or rash. Primary prevention of maternal infections during pregnancy is key to the prevention of congenital infection, and resources (if available) should focus on public health promotion and pre-marital counselling.
