Background: Although laparoscopic cholecystectomy (LC) is a minimally invasive surgery, it can cause moderate to severe postoperative pain. Erector spinae plane (ESP) and transversus abdominis plane (TAP) blocks are considered effective means for pain management in such cases; however, there is inconclusive evidence regarding their analgesic efficacy. This meta-analysis aimed to compare the efficacy of ESP block and TAP block for pain control in LC.

Objective: Although the caesarean delivery (CD) rate has substantially increased, little is known about its impacts when performed in the first and second stages of labour on fetomaternal outcomes, especially among referred mothers. Thus, this study aimed to investigate the association between CDs performed during the first and second stages of labour and poor maternal and neonatal outcomes among mothers referred to tertiary centres.

Setting: This retrospective cohort study analysed medical records of mother-infant pairs from September 2020 to May 2023 in Southern Ethiopia.

Background: The time interval between skin incision and delivery (S-D) is crucial in determining neonatal outcome; however, little is known about the influencing factors and their impact on neonatal outcomes, particularly among emergency cesarean deliveries (ECD) indicated for fetal distress. This study investigated the factors influencing S-D time and their effects on neonatal outcomes among mothers who underwent ECD for non-reassured fetal heart rate status.

Methods: This retrospective cohort study involved 426 mother-infant pairs over four years.

Background: The term premature rupture of the membranes is the rupture of the membranes before the onset of labor beyond 37 weeks of gestation. Several factors, including obstetric, gynecologic, socioeconomic, and medical, are identified as potential risk factors. This clinical event has detrimental maternal and neonatal complications.

Purpose: Although the underlying causes for preterm birth are thought to be multifactorial irrespective of delivery mode, no study investigated its risk factors amongst cesarean deliveries (CD). Thus, we aimed to identify potential risk factors for the occurrence of preterm birth (PTB) among intrapartum CD.

Methods: Data from 1659 singleton intrapartum CDs were retrospectively recruited using medical records and an obstetric database.

Background: Despite the burden of anemia during pregnancy has been extensively studied, the magnitude of postpartum anemia (PPA) and its predictors, especially after caesarean delivery remains unexplored. Therefore, we investigated the prevalence of postpartum anemia, and its predictors among women who underwent cesarean delivery.

Methods: A retrospective study was conducted among women who underwent caesarean delivery in Southern Ethiopia.

Background: Meconium aspiration syndrome is respiratory distress diagnosed in neonates delivered with meconium-stained amniotic fluid that is unexplained by other pathologies. It has severe neonatal respiratory complications and a significant impact on the prevalence of neonatal mortality.

Objective: To identify the incidence and determinants associated with meconium aspiration syndrome among mothers with meconium-stained amniotic fluid after emergency cesarean section in Wolkite University specialized hospitals in Ethiopia from September 1, 2021, to August 30, 2022.

Severe postpartum hemorrhage is an obstetric emergency that needs immediate intervention and is a leading cause of maternal death. Despite its significant health burden, little is known, about its magnitude and risk factors, especially after cesarean delivery in Ethiopia. This study aimed to evaluate the incidence and predictors of severe postpartum hemorrhage following cesarean section.

Background: Uterine rupture is defined as tearing of the uterine wall during pregnancy or delivery. It can occur during pregnancy or labor and delivery. Rupture of the uterus is a catastrophic event resulting in the death of the baby, and severe maternal morbidity and mortality Despite different interventions done by stakeholders, it remained one of the leading public problems in developing countries like Ethiopia.

Background: Previous studies have found an association between various predictors and extubation failure (EF) in intensive care units (ICUs). However, this problem remains unexplored in low-resource settings, where predicting the extubation outcomes are more challenging. This study investigates the incidence of EF and its predictors among patients who received mechanical ventilation (MV).

Background: Previous studies have found an association between various predictors and perforated appendicitis. However, there is limited evidence of studies determining the severity of acute appendicitis (AA) in resource-limited settings. Thus, this study aimed to identify predictors and outcomes of perforated appendicitis (PA) in sub-Saharan countries.

Introduction And Importance: Fibroadenoma of the male breast is a rarely diagnosed lesion that often occurs concurrently with gynecomastia and the intake of medications that alter sex hormone levels. Herein, we report the first case of fibroadenoma of the male breast, presenting with medullary thyroid cancer. In addition, we reviewed the current management strategies for fibroadenoma of the male breast in the literature.

Introduction And Importance: Appendicitis causing intestinal obstruction by forming a knot around a small bowel is uncommon. Preoperative diagnosis is challenging as the typical presentations of appendicitis are not usually seen. The diagnosis of appendicular knotting is usually an intraoperative surprise.

Background: During transverses abdominal plane block (TAP) procedure to provide analgesia in cesarean section (CS) operation, the use of perineural dexamethasone as an additive agent may improve pain relief and may cause a prolonged block duration. This study aims to investigate whether perineural dexamethasone, when added to bupivacaine local anesthetic agent during a TAP block, may provide adequate pain relief without adverse events.

Methods: This is a prospective cohort study of fifty-eight patients undergoing elective CS with spinal anesthesia.

Background: Cesarean delivery (CD) is a commonly performed obstetric surgical procedure and causes moderate to severe postoperative pain. Wound site infiltration (WSI) is becoming a technique to provide postoperative analgesia in a limited-resource setting in regardless of controversy on its effectiveness. The current study is to assess its effectiveness as a part of postoperative analgesia for parturients undergoing elective Cesarean section.
