RESUMEN

In low- and middle-income countries, urban and rural settings are distinct communities with the latter being more likely to have limited resources, particularly in health care services. We assessed the inequality in health care services in urban and rural settings in South Africa, highlighting the disparities between public and private health services, given that the latter are located mainly in urban settings. Rural settings suffer the highest inequality in the availability of drugs and supplies, overcrowding of health care facilities, delays in transporting patients, inadequate emergency medical services, and lack of experienced health care professionals. Rural settings also preferentially have a shortage of various levels of health care services, and increased security threats by criminals. In addition to specific remedies, the overarching key to solving these challenges is socio-economic growth, as well as visionary and compassionate leadership with integrity and accountability, which ensures policy development, implementation, monitoring, and evaluation.

RESUMEN

Background: The risk of uterine perforation during manual vacuum aspiration (MVA) is reduced by using Karman cannula (which has a rounded tip) during the procedure. Methods: A 35-year-old multigravida at 13 gestational weeks presented with vaginal bleeding of a day duration and ultrasound evidence of retained products of conception suggestive of incomplete miscarriage. The patient was rhesus D positive and stable. She had MVA which was performed using Karman cannula, and developed severe vaginal bleeding. The differential diagnoses were incomplete uterine evacuation and uterine perforation. Results: During a laparotomy in Lloyd-Davies position, haemoperitoneum and six uterine perforations on the anterior and fundal parts, each approximately 5 mm in length (Figure 1), were found. The perforations were repaired and a check uterine curettage under oxytocic cover showed an empty uterus. The abdominal cavity was washed and closed. She was transfused three units of red blood cell concentrate and had a normal six weeks follow-up. Conclusion: When an instrument inserted into the uterus is pushed beyond the estimated depth of the uterus, a perforation must be suspected and the condition may be managed conservatively. A surgical procedure complicated by surgeon's loss of perception (in this case tactile) of tissues' anatomy is hazardous.

RESUMEN

Assigning a primary cause of death to a deceased patient who had multiple principal diagnoses including coronavirus disease 2019 (COVID-19) is challenging because of the difficulty in selecting the most appropriate cause. To proffer a solution, the authors reviewed the literature on assigning a primary cause of death. In 2015, the Nnabuike-Jagidesa (NJ) model II was devised to improve the International Classification of Diseases and related health problems, 10th revision (ICD-10) guideline on how to assign a primary cause of death. The NJ model II stipulates that when there are multiple diagnoses with no plausible explanation that one of the illnesses could have resulted in the other clinical conditions, the single most appropriate primary cause of death is the condition with the highest case fatality ratio in that setting. In the index report, the authors opine that if the case fatality ratios are similar, the following objective criteria (listed in the order of priority) should be used to assign a primary cause of death: condition with the highest infection fatality ratio, condition that was the main indication for the last acute surgical or invasive procedure performed (during the course of the same ill-health) before the death and the disease that theoretically affects the highest number of body organs. Additionally, a clinical descriptor should be used when none of the objective criteria are satisfied. This novel approach, termed the modified NJ model II, is expected to improve the objectivity and reproducibility of the assigned primary cause of death in a deceased who had multiple diagnoses, which may include COVID-19.

RESUMEN

BACKGROUND: Hypertension is a major cause of morbidity and mortality and its control has important clinical and socio-economic benefits to the family and community. Unfortunately, the extent of blood pressure (BP) control and its potential predictors in hypertensive patients in many rural communities in low-resource settings are largely unknown. This study assessed the extent of uncontrolled BP and its predictors amongst hypertensive patients accessing primary health care in a rural community in South Africa. METHODS: This cross-sectional study included 422 randomly selected hypertensive patients. Demographic and clinical data were collected using structured face-to-face questionnaire supplemented by respondents' clinical records. RESULTS: Obesity plus overweight (n = 286, 67.8%) and diabetes (n = 228, 54.0%) were the most common comorbidities. Treatment adherence was achieved in only 36.3% and BP was controlled to target in 50.2% of the respondents. Significant predictors of uncontrolled BP were poor treatment adherence (odds ratio [OR] = 15.88, 95% confidence interval [CI] = 8.96, 28.14, p  0.001), obesity compared with normal weight and overweight (OR = 3.75, 95% CI = 2.17, 6.46, p  0.001) and being a diabetic (OR = 2.83, 95% CI = 1.74, 4.61, p  0.001). CONCLUSION: Poor adherence to treatment was the major predictor of uncontrolled BP. The increase in uncontrolled BP in the presence of diabetes and/or obesity as risk predictors, indicates the need for appropriate behaviour change/interventions and management of these conditions in line with the health belief model (HBM). We also propose the use of Community-Based Physical and Electronic Reminding and Tracking System (CB-PERTS) to address poor treatment adherence.

RESUMEN

OBJECTIVE: To describe risk factors and outcomes of pregnant women infected with SARS-CoV-2 admitted to South African healthcare facilities. METHODS: A population-based cohort study was conducted utilizing an amended International Obstetric Surveillance System protocol. Data on pregnant women with SARS-CoV-2 infection, hospitalized between April 14, 2020, and November 24, 2020, were analyzed. RESULTS: A total of 36 hospitals submitted data on 673 infected hospitalized pregnant women; 217 (32.2%) were admitted for COVID-19 illness and 456 for other indications. There were 39 deaths with a case fatality rate of 6.3%: 32 (14.7%) deaths occurred in women admitted for COVID-19 illness compared to 7 (1.8%) in women admitted for other indications. Of the women, 106 (15.9%) required critical care. Maternal tuberculosis, but not HIV co-infection or other co-morbidities, was associated with admission for COVID-19 illness. Rates of cesarean delivery did not differ significantly between women admitted for COVID-19 and those admitted for other indications. There were 179 (35.4%) preterm births, 25 (4.7%) stillbirths, 12 (2.3%) neonatal deaths, and 162 (30.8%) neonatal admissions. Neonatal outcomes did not differ significantly from those of infected women admitted for other indications. CONCLUSION: The maternal mortality rate was high among women admitted with SARS-CoV-2 infection and higher in women admitted primarily for COVID-19 illness with tuberculosis being the only co-morbidity associated with admission.

RESUMEN

Transient gestation hypertension is a contributor to adverse pregnancy outcomes particularly when it progresses to pre-eclampsia (PE). This requires frequent monitoring. We illustrate the need for stringent monitoring of gestational hypertension, transient gestational hypertension (TGH) and PE without severe features and conducted a brief rapid review of the literature. Two cases are presented: Firstly, a 25-year-old primigravida at 30 gestational weeks who had an isolated TGH with high blood pressure (BP) of 141/87 mmHg, which was not investigated. Four weeks later, she presented with a BP of 202/128 mmHg, imminent eclampsia and intrauterine foetal death and had an uncomplicated induction of labour and delivered a 1400 g macerated male stillborn. Secondly, a 30-year-old primigravida at 30 gestational weeks who developed PE but her monitoring was compromised initially by inadequate healthcare capacity including unavailability of hospital bed-space for inpatient care and later by poor clinic attendance as a result of poor finances. At 32 gestational weeks, she presented with decreased foetal movement and was diagnosed as haemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome and intrauterine foetal death. She was stabilised, had induction of labour and delivered a 1400 g male macerated stillborn. Thereafter, the need for her to go home to complete the cultural burial rites of her baby and the pressure from her workplace resulted in an inadequate postpartum follow-up care. In conclusion, transient gestational hypertension is associated with adverse maternal and foetal outcomes, including foetal demise. Unavailability of hospital bed-space and poor personal finances interfere with stringent monitoring of hypertensive disorders and can be associated with adverse pregnancy outcomes. Stringent laboratory monitoring in these cases is defined by the authors as testing at least blood levels of serum Creatinine, Haemoglobin concentration, Alanine transaminase and Platelet count (abbreviated as 'CHAP') weekly.

RESUMEN

In South Africa, large numbers of individuals with medical emergencies initially visit a general practitioner or family physician. In the case of maternity care, this may occasionally involve acute onset of severe hypertension during the antenatal period. Primary care providers (PCPs) are therefore faced with the conundrum of treating and stabilising high blood pressure or referring the patient to an appropriate hospital. Case reviews within groups of medical practitioners provide an opportunity for learning in the practical management of obstetric emergencies. The case history of a patient with severe hypertension was presented, and reflections on this patient encounter were highlighted. Amongst the challenges faced by generalists in their interactions with the public health sector are availability of standard clinical protocols, medicines, the need to work in partnership and the need to have 'feedback'.

RESUMEN

BACKGROUND: Eclampsia remains a major cause of maternal mortality, particularly in teenage pregnancies. Healthcare professionals providing antenatal must regard teenagers as a high risk group for the pre-eclampsia-eclampsia syndrome. SETTING: Data extracted from the South African Saving Mothers Report: 2014-2016. AIM: To establish the clinical details in teenage maternal deaths owing to eclampsia. METHOD: Retrospective review of the case records and maternal death assessment forms of teenagers that died due to eclampsia during 2014-2016. RESULTS: There were 47 teenagers (aged 14 to 19 years) who died from eclampsia. Of these 18 out of 47 (38%) deaths occurred in the post-partum period. Forty (85.1%) of the patients had antenatal care. Three (6.4%) had post-partum eclampsia, and of the remaining 44 of the 47 (93.6%), the gestational age at first occurrence of a seizure ranged from 25 to 39 weeks. The blood pressures at the time of seizure ranged from systolic of 131 to 210 mmHg and diastolic of 89 to 130 mmHg. The commonest final causes of death were intracerebral haemorrhage associated with severe hypertension and multi-organ failure. Avoidable factors included transport delays, referral to the wrong levels of health care and poor care by health professionals. CONCLUSION: Teenage pregnancy is a risk factor for eclampsia-related death; awareness of borderline elevations of blood pressure levels from baseline values (prehypertension levels) and taking following national guidelines on the management of hypertensive disorders of pregnancy will decrease deaths from eclampsia.

RESUMEN

The placenta accreta spectrum (PAS) describes invasion and adherence of the placenta onto or beyond the myometrium. Prenatal imaging improves management outcomes. In low- and middle-income countries (LMIC), however, the unavailability of ultrasonography in some health facilities delays the diagnosis, particularly if the prenatal period is asymptomatic. Following vaginal delivery, it often manifests as failure to remove a retained placenta manually. In the absence of haemorrhage, expectant management involving leaving the placenta in situ, is an option. In the presence of haemorrhage and/or sepsis, hysterectomy is usually recommended. We present a case of an expectantly managed PAS following a spontaneous preterm vaginal birth. The patient developed puerperal uterine prolapse with the placenta in situ, a previously unreported complication, but this was successfully reduced manually.

RESUMEN

Objective: To determine blood pressure (BP) patterns in the immediate postpartum period in preeclampsia with severe features (sPE) and normotensive pregnant women who had cesarean deliveries (CD).Study design: The BP levels of two groups comprising 50 sPE and 90 normotensive pregnant women who had CD were measured before delivery and on days 0-3 postpartum at four time points (05:00, 08:00, 14:00, and 22:00). Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PIGF) were measured in the maternal serum ≤48 h before delivery.Results: Antihypertensive therapy was administered to 98, 96, 82, 78, and 56% of sPE antepartum and on postpartum days 0-3, respectively. De novo postpartum hypertension (BP ≥ 140/90 mmHg) occurred in 24.4% (22/90) of the normotensive group but only one required antihypertensive therapy. The occurrence of de novo postpartum hypertension was associated with maternal weight before delivery ≥ 84.5 kg (relative risks (RR) 2.6, CI 95% 1.2-5.8, p = .017), and body mass index before delivery ≥ 33.3 kg/m2 (RR 2.9, CI 95% 1.3-6.4, p = .008). In sPE, the BP decreased between predelivery period and postpartum day 0. From days 1 to 3 postpartum, there was a continuous increase in the daily mean BPs in both groups, with average daily increments (systolic/diastolic) being 5.6/4.6 mmHg and 0.6/1.3 mmHg in the sPE and normotensive women, respectively. Patient's group and time had a significant effect on BP, p < .001. Overall, daily mean BPs were higher in the sPE than the normotensive group (p < .001). Perceived stress (p = .022), low birth weight (p = .002), 5 min Apgar score ≤ 6 (p < .001) were significantly higher in the sPE group. sFlt-1/PIGF ratio was high in the hypertensive groups: sPE versus normotensive group, p < .001; de novo postpartum hypertension versus normotensives group that remained normotensive, p = .102.Conclusion: Postpartum BP and antihypertensive requirements are important considerations in managing sPE and normotensive pregnancies. sPE is associated with increased maternal stress and poor perinatal outcomes.

RESUMEN

Measurement of blood pressure is essential for clinical management of patients. To obtain an accurate blood pressure reading, the use of a validated device and an appropriate technique are required. This is of particular importance in pregnancy where the physiological changes affect vessel wall compliance. Moreover, currently it is difficult to predict in early pregnancy (prior to 20 weeks of gestation) which women would develop hypertension or pre-eclampsia. For this reason, blood pressure devices require validation in pregnancy and in hypertensive disorders of pregnancy to ensure that accurate readings are obtained and utilised for clinical decisions, otherwise the safety of the mother or the foetus/neonate or both may be compromised. The authors provide a narrative review on devices and techniques for blood pressure measurement in pregnancy and hypertensive disorders of pregnancy as well as the associated challenges.

RESUMEN

PURPOSE: Pregnancy causes physiological changes in maternal organ systems, and blood pressure (BP) is one of the variables affected. This review is focusing on the physiology of BP relevant to the management of hypertension in pregnancy. MATERIALS AND METHODS: A detailed literature search was performed using electronic databases (including WorldCat, PubMed, MEDLINE, Google Scholar) to retrieve and review reports related to physiology of BP in pregnancy. RESULTS: During pregnancy, there is vasodilation caused by mediators such as increased levels of progesterone and nitric oxide. The vasodilation leads to a reduction in vascular resistance, BP, and renal blood flow. In compensation, the following postulated events occur: activation of renin-angiotensin-aldosterone axis, resetting of osmotic threshold for thirst, and an increase in the production of vasopressin. Sodium and water conservation ensue to increase the total body water, end-diastolic volume, cardiac output, and BP. The increase in cardiac output incompletely compensates for the decreased vascular resistance, and BP therefore decreases in midpregnancy and returns to prepregnancy level toward term. CONCLUSIONS: An understanding of the physiological changes in BP is essential for appropriate management of pregnancy-related hypertension.

RESUMEN

OBJECTIVE: The baseline blood pressure (BP) readings of an automated device that have not been validated in pregnancy require comparison with those from a reference standard before the device is utilized in pregnancy. We aimed to perform a baseline check of BP readings of an automated device, Mindray iMEC12 patient monitor, in severe pre-eclampsia and healthy pregnancy. STUDY DESIGN: The BP of 50 severe pre-eclamptic and 90 normotensive pregnancies were measured using Mindray iMEC12 patient monitor (test device) and Welch Allyn 767 aneroid sphygmomanometer (reference device). A pass in either the International Organization for Standardization (ISO) or British Hypertension Society (BHS) rating was considered acceptable. The cumulative percentage of absolute BP difference between the test and reference devices within 5, 10 and 15 mmHg were calculated to rate the test device according to the BHS grades (A, B, C or D). The ISO recommends that an accurate device should achieve a mean BP difference ±â€¯SD of ≤5 ±â€¯8 mmHg. RESULTS: The mean BP difference between the test and reference devices were 1.27 ±â€¯7.51 mmHg and 0.05 ±â€¯6.09 mmHg for systolic and diastolic BPs respectively. The test device achieved the BHS grades B and A rating in systolic and diastolic BPs respectively. In each of the 2 groups (pre-eclamptic and normotensive pregnancies), the test device also satisfied the set pass criteria. CONCLUSIONS: In settings that do not have a validated BP device, Mindray iMEC12 patient monitor may be used for BP measurement in normotensive and severe pre-eclamptic pregnancies.

RESUMEN

The cause of pre-eclampsia is unknown. Different postulates have been developed to explain its pathogenesis. The two-stage theory and angiogenic imbalance are two notable postulates of the disease. Together, they propose that there is a lack of cytotrophoblastic invasion of the uterine spiral arteries in pre-eclampsia. The lumen of these arteries remains narrow instead of converting to the wide channels seen in normal pregnancy, and result in poor placental perfusion. Coupled with maternal susceptibility, this process leads to the release of mediators, including an excess of anti-angiogenic factors that result in the clinical manifestations of the disease. Circulating levels of anti-angiogenic factors such as soluble fms-like tyrosine kinase-1 increase, whereas pro-angiogenic factors such as placental growth factor decrease. Assessment of the circulating concentrations of these angiogenic factors, such as the soluble fms-like tyrosine kinase-1/placental growth factor ratio, has diverse clinical relevance in pre-eclampsia. The present review describes the role of angiogenic factors in the pathogenesis and management of pre-eclampsia.

RESUMEN

In South Africa, new drug regimens (WHO treatment Option B) used to manage HIV infection in pregnancy and the national strategic plan on HIV have resulted in improved health outcomes. Among these outcomes are reductions in the following: mother-to-child transmission (MTCT) of HIV to 2.4%; maternal deaths attributable to HIV; and adverse reactions due to antiretroviral therapy (ART). The present article describes these new drug regimens and the national strategic HIV management plan, as well as their challenges and the implications of improved health outcomes. Such outcomes imply that further decreases in MTCT of HIV, and HIV attributable maternal deaths are possible if potential challenges are addressed and treatment option B+ offered. A confidential enquiry into each case of MTCT is advocated to reduce vertical transmission rates to zero levels.

RESUMEN

We present a case of spontaneous antepartum uterine rupture through a previous lower segment Caesarean section (LSCS) scar with clinical features mimicking an advanced extrauterine pregnancy (AEUP) in a twin pregnancy at 28 weeks gestation. This report illustrates the need to consider a diagnosis of a ruptured uterus in any patient with a previous abdominal delivery who presents with mild abdominal tenderness and an ultrasonographic image suggestive of demised fetus in the intra-peritoneal cavity.
