RESUMO

Syphilis, 'the great imitator', caused by Treponema pallidum infection, remains a complex and multifaceted disease with a rich history of clinical diversity. This guideline aims to be a comprehensive guide for healthcare workers in Southern Africa, offering practical insights into the epidemiology, pathogenesis, clinical manifestations, diagnostic testing, therapeutic principles, and public health responses to syphilis. Although the syphilis burden has declined over the years, recent data indicate a troubling resurgence, particularly among pregnant women and neonates. This guideline highlights the diagnostic challenges posed by syphilis, stemming from the absence of a single high-sensitivity and -specificity test. While treatment with penicillin remains the cornerstone of treatment, alternative regimens may be used for specific scenarios. We highlight the importance of thorough patient follow-up and management of sex partners to ensure optimal care of syphilis cases. In the context of public health, we emphasise the need for concerted efforts to combat the increasing burden of syphilis, especially within high-risk populations, including people living with HIV.

RESUMO

The use of tranexamic acid for postpartum hemorrhage has entered obstetrical practice globally with the evidence-based expectation of saving lives. This improvement in the care of women with postpartum hemorrhage has come at a price. For the anesthetist, having tranexamic acid ampoules close at hand would seem an obvious strategy to facilitate its use during cesarean delivery, an important setting for severe hemorrhage. Tragically, we have identified a number of recent instances of inadvertent intrathecal administration of tranexamic acid instead of local anesthetic for spinal anesthesia. Reported cases of this catastrophic error seem to be increasing. The profound neurotoxicity of tranexamic acid causes rapid-onset convulsions, with mortality of 50%. How can these tragic errors be averted? Drug safety alerts have been issued by the US Food and Drug Administration and the World Health Organization, but that is not enough. We recommend extensive dissemination of information to raise awareness of this potential hazard, and local hospital protocols to ensure that tranexamic acid is stored separately from anesthetic drugs, preferably outside the operating room and with an auxiliary warning label. Implementation of safety strategies on a very large scale will be needed to ensure that the life-saving potential of tranexamic acid is not eclipsed by drug-error mortality.

RESUMO

BACKGROUND: In 2013, a pregnancy exposure registry and birth defects surveillance (PER/BDS) system was initiated in eThekwini District, KwaZulu-Natal (KZN), to assess the impact of antiretroviral treatment (ART) on birth outcomes. OBJECTIVES: At the end of the first year, we assessed the risk of major congenital malformations (CM) and other adverse birth outcomes (ABOs) detected at birth, in children born to women exposed to ART during pregnancy. METHOD: Data were collected from women who delivered at Prince Mshiyeni Memorial Hospital, Durban, from 07 October 2013 to 06 October 2014, using medicine exposure histories and birth outcomes from maternal interviews, clinical records and neonatal surface examination. Singleton births exposed to only one ART regimen were included in bivariable analysis for CM risk and multivariate risk analysis for ABO risk. RESULTS: Data were collected from 10 417 women with 10 517 birth outcomes (4013 [38.5%] HIV-infected). Congenital malformations rates in births exposed to Efavirenz during the first trimester (T1) (RR 0.87 [95% CI 0.12-6.4; p = 0.895]) were similar to births not exposed to ART during T1. However, T1 exposure to Nevirapine was associated with the increased risk of CM (RR 9.28 [95% CI 2.3-37.9; p = 0.002]) when compared to the same group. Other ABOs were more frequent in the combination of HIV/ART-exposed births compared to HIV-unexposed births (29.9% vs. 26.0%, adjusted RR 1.23 [1.14-1.31; p < 0.001]). CONCLUSION: No association between T1 use of EFV-based ART regimens and CM was observed. Associations between T1 NVP-based ART regimen and CM need further investigation. HIV- and ART-exposed infants had more ABOs compared to HIV-unexposed infants.

RESUMO

Training programmes to improve health worker skills in managing obstetric emergencies have been introduced in various countries with the aim of reducing maternal mortality through these interventions. In South Africa, based on an ongoing confidential enquiry system started in 1997, detailed information about maternal deaths is published in the form of regular 'Saving Mothers' reports. This article tracks the recommendations made in successive Saving Mothers reports with regard to emergency obstetric training, and it assesses the impact of these recommendations on reducing maternal mortality. Since 2009, South Africa has had its own training package, Essential Steps in the Management of Obstetric Emergencies (ESMOE), which the last three Saving Mothers reports have specifically recommended for all doctors and midwives working in maternity units. A special emphasis has been placed on the need for the simulation training component of ESMOE, also called obstetric 'fire drills', to be integrated into the clinical routines of all maternity units. The latest Saving Mothers report (2011-2013) suggests there has been little progress so far in improving emergency obstetric skills, indicating a need for further scale-up of ESMOE training in the country. The example of the KwaZulu-Natal province of South Africa is used to illustrate the process of scale-up and factors likely to facilitate that scale-up, including the introduction of ESMOE into the undergraduate medical training curriculum. Additional factors in the health system that are required to convert improved skills levels into improved quality of care and a reduction in maternal mortality are discussed. These include intelligent government health policies, formulated with input from clinical experts; strong clinical leadership to ensure that doctors and nurses apply the skills they have learnt appropriately, and work professionally and ethically; and a culture of clinical governance.

RESUMO

The effect of HIV infection on maternal mortality is best documented in South Africa, where HIV prevalence rates in pregnancy are among the highest in the world. Since 1998, detailed data on maternal deaths in South Africa have been available in the form of Confidential Enquiries reports. The latest report (Saving Mothers Report, 2005-2007) suggests that the maternal mortality ratio in HIV-infected women was about 10 times higher than in uninfected women. This was in a context where only a small minority of HIV-positive pregnant women were receiving HAART. The most common causes of maternal death among HIV-positive women were nonpregnancy-related infections, including AIDS, pneumonia, tuberculosis, and meningitis. HIV-infected pregnant women were also at greater risk of dying from pregnancy-related sepsis and complications of abortion than their uninfected counterparts. Reduction of HIV-related maternal deaths must be seen as a worldwide priority in maternal health care.

RESUMO

BACKGROUND: Our objective was to estimate the effect of various childbirth care packages on neonatal mortality due to intrapartum-related events ("birth asphyxia") in term babies for use in the Lives Saved Tool (LiST). METHODS: We conducted a systematic literature review to identify studies or reviews of childbirth care packages as defined by United Nations norms (basic and comprehensive emergency obstetric care, skilled care at birth). We also reviewed Traditional Birth Attendant (TBA) training. Data were abstracted into standard tables and quality assessed by adapted GRADE criteria. For interventions with low quality evidence, but strong GRADE recommendation for implementation, an expert Delphi consensus process was conducted to estimate cause-specific mortality effects. RESULTS: We identified evidence for the effect on perinatal/neonatal mortality of emergency obstetric care packages: 9 studies (8 observational, 1 quasi-experimental), and for skilled childbirth care: 10 studies (8 observational, 2 quasi-experimental). Studies were of low quality, but the GRADE recommendation for implementation is strong. Our Delphi process included 21 experts representing all WHO regions and achieved consensus on the reduction of intrapartum-related neonatal deaths by comprehensive emergency obstetric care (85%), basic emergency obstetric care (40%), and skilled birth care (25%). For TBA training we identified 2 meta-analyses and 9 studies reporting mortality effects (3 cRCT, 1 quasi-experimental, 5 observational). There was substantial between-study heterogeneity and the overall quality of evidence was low. Because the GRADE recommendation for TBA training is conditional on the context and region, the effect was not estimated through a Delphi or included in the LiST tool. CONCLUSION: Evidence quality is rated low, partly because of challenges in undertaking RCTs for obstetric interventions, which are considered standard of care. Additional challenges for evidence interpretation include varying definitions of obstetric packages and inconsistent measurement of mortality outcomes. Thus, the LiST effect estimates for skilled birth and emergency obstetric care were based on expert opinion. Using LiST modelling, universal coverage of comprehensive obstetric care could avert 591,000 intrapartum-related neonatal deaths each year. Investment in childbirth care packages should be a priority and accompanied by implementation research and further evaluation of intervention impact and cost. FUNDING: This work was supported by the Bill and Melinda Gates Foundation through a grant to the US Fund for UNICEF, and to Saving Newborn Lives Save the Children, through Save the Children US.

RESUMO

Massive hemoptysis during pregnancy has been infrequently reported. The management of massive hemoptysis in an immunocompromised 22-year-old woman positive for human immunodeficiency virus undergoing treatment for cavitating pulmonary tuberculosis in the last trimester of pregnancy is reported. The difficulties encountered in applying our standard protocol for massive hemoptysis in this instance are described. The patient was managed by emergency cesarean section and lobectomy.
