Background: Eclampsia and pre-eclampsia are well-recognized causes of maternal and neonatal mortality in low income countries, but are never studied in a district hospital. In order to get reliable data to facilitate the hospital's obstetric audit a retrospective medical record study was performed in Ndala Hospital, Tanzania.
Methods: All patients diagnosed with severe pre-eclampsia or eclampsia between July 2011 and December 2012 were included. Medical records were searched immediately following discharge or death. General patient characteristics, medical history, obstetrical history, possible risk factors, information about the current pregnancy, antenatal clinic attendance and prescribed therapy before admission were recorded. Symptoms and complications were noted. Statistical analysis was done with Epi Info®.
Results: Of the 3398 women who gave birth in the hospital 26 cases of severe pre-eclampsia and 55 cases of eclampsia were diagnosed (0.8 and 1.6%). Six women with eclampsia died (case fatality rate 11%). Convulsions in patients with eclampsia were classified as antepartum (44%), intrapartum (42%) and postpartum (15%). Magnesium was given in 100% of patients with eclampsia and was effective in controlling convulsions. Intravenous antihypertensive treatment was only started in 5% of patients. Induction of labour was done in 29 patients (78% of women who were not yet in labour). Delivery was spontaneous in 67%, assisted vaginal (ventouse) in 14% and by Caesarean section in 19% of women. Perinatal deaths occurred in 30% of women with eclampsia and 27% of women with severe pre-eclampsia and were associated with low birth weight and prolonged time between admission and birth.
Conclusions: 2.4% of women were diagnosed with severe pre-eclampsia or eclampsia. The case fatality rate and overall perinatal mortality were comparable to other reports. Better outcomes could be achieved by better treatment of hypertension and starting induction of labour as soon as possible.

Importance: Chronic hypertension and preeclampsia are leading risk enhancers for maternal-neonatal morbidity and mortality. Severe maternal morbidity (SMM) indicators include heart, kidney, and liver disease, but studies have not excluded patients with preexisting diseases that define SMM. Thus, SMM risks for uncomplicated chronic hypertension specific to preeclampsia remain unclear.

Aim: Our study aimed to evaluate the predictive value of Placental growth factor (PlGF), Vitamin D, and systemic inflammatory index for assessing preeclampsia risk and severity.
Materials And Methods: This retrospective cohort study included 457 pregnant individuals who delivered at our hospital between March 2023 and October 2024. Participants were divided into three groups: control (n = 217), mild preeclampsia (n = 101), and severe preeclampsia (n = 67).

Introduction: arterial hypertension (AH) may persist beyond three months postpartum after preeclampsia, increasing the long-term risk of cardiovascular complications. The purpose of this study is to describe the epidemiological aspects and factors associated with persistent hypertension following preeclampsia.
Methods: we conducted a longitudinal descriptive study, from January 2022 to June 2023.

Introduction: Preeclampsia (PE) is a common vascular pregnancy disorder affecting maternal and fetal metabolism with severe immediate and long-term consequences in mothers and infants. During pregnancy, metabolites in the maternal circulation pass through the placenta to the fetus. Meconium, a first stool of the neonate, offers a view to maternal and fetoplacental unit metabolism and could add to knowledge on the effects of PE on the fetus and newborn.

Wernicke's Encephalopathy (WE) is a rare but severe condition primarily caused by thiamine deficiency, often seen in pregnant women who experience severe vomiting, such as in hyperemesis gravidarum. This case report details a 38-year-old woman at 27 weeks of gestation who developed altered consciousness, cerebellar ataxia, and hyperlactatemia following persistent vomiting. Brain MRI demonstrated characteristic bilateral abnormalities consistent with WE.
