Symptomatic congenital syphilis in a tertiary neonatal unit in Cape Town, South Africa: High morbidity and mortality in a preventable disease.

BACKGROUND: Despite preventive measures and effective treatment, congenital syphilis continues to impact significantly on neonatal morbidity and mortality. There has been no recent South African (SA) published literature reviewing congenital syphilis, particularly in the context of a tertiary neonatal setting. OBJECTIVES: To describe the clinical features of symptomatic neonates with congenital syphilis and to identify modifiable patient, clinical and health facility factors that contributed to syphilis infection. METHODS: All positive serological tests for syphilis performed in neonates at Groote Schuur Hospital (GSH), Cape Town, SA, between 1 January 2011 and 31 December 2013 were obtained. Folders were reviewed, and neonates with clinical signs of congenital syphilis were included. RESULTS: Of 50 symptomatic neonates, 19 (38%) died. Twenty-eight mothers (56%) were unbooked and therefore received no antenatal care. Most mothers (98%) were inadequately treated. Health worker-related failures included poor notification and partner tracing as well as failure to recheck syphilis serology after 32 weeks' gestation in mothers who initially tested negative. Thirty-four neonates required intensive care unit admission. Two significant predictors of mortality were 1-minute and 5-minute Apgar scores <5. Hydrops fetalis was an independent risk factor for mortality, as were moderate to severely abnormal cranial ultrasound scan findings. CONCLUSIONS: Congenital syphilis in neonates admitted to the GSH neonatal unit was associated with substantial morbidity and mortality. The modifiable factors identified represent inadequate antenatal healthcare and health system failures. These factors are longstanding, highlighting the need to establish governance and audit processes and address the continuing socioeconomic and sociocultural barriers that mothers face as a way forward in ultimately eliminating this entirely preventable disease.

Background. Despite preventive measures and effective treatment, congenital syphilis continues to impact significantly on neonatal morbidity and mortality. There has been no recent South African (SA) published literature reviewing congenital syphilis, particularly in the context of a tertiary neonatal setting. Objectives. To describe the clinical features of symptomatic neonates with congenital syphilis and to identify modifiable patient, clinical and health facility factors that contributed to syphilis infection.

Syringe drivers: incorrect selection of syringe type from the syringe menu may result in significant errors in drug delivery.

There have been many reported adverse incidents due to syringe driver use, most of which have been attributable to human error. In this paper we present a previously unreported, but potentially widespread practice which may result in significant over or under-delivery of medication. Even with the naked eye it is evident that syringes of equal volume have different dimensions and to quantify this we sectioned a range of syringes and measured the inner and outer dimensions. Extensive menus for syringe brand and volumes are available on syringe drivers, offering users greater flexibility. However, this feature also allows users to select an incorrect syringe brand with potential consequences for drug delivery. We measured outputs under all selectable permutations, to determine the degree of fluid delivery variation and discovered inaccuracies in volumes ranging from 10% under-delivery to 24% over-delivery. There is a wide variation in syringe metrics and complex syringe menus may increase errors, resulting in significant under or over-delivery of medication. Availability of more than one brand of syringe in a clinical area increases the risk of adverse drug delivery events. Systems need to be implemented to minimise the risk of adverse events.
