Acute Transverse Myelitis in Pregnancy—A Case Report and a Literature Review

Open Journal of Obstetrics and Gynecology 2024年第9期14卷 1512-1521页

作者： huda Abbas ali Isa Fatema hasan zainab Mohd Al Aswad Naeema Ahmed Abdulkareem Salmaniya Medical Complex Manama Bahrain Ob Gyn Faculty Arabian Gulf University Manama Bahrain

Purpose: This case report highlights a rare instance of a 26-week pregnant woman presenting with limb numbness, diagnosed with acute transverse myelitis (ATM) following COVID-19 vaccination. Notably, she tested positive for neuromyelitis optica (NMO) but did not exhibit the typical symptoms of blurred vision. Methods: Data were collected from I Seha in governmental hospitals in Bahrain, providing a comprehensive overview of the patient’s clinical journey. Results: The patient was treated with carbamazepine, steroids, and clexane, leading to the successful delivery of a healthy baby at 34 weeks. however, two years postpartum, she reported new episodes of blurred vision and numbness. Subsequent treatment with Rituximab resulted in significant improvement, with a diagnosis of Devic’s disease established. Conclusion: Acute transverse myelitis is a rare condition, particularly during pregnancy, and in this case, symptoms of Devic’s disease were masked by the absence of blurred vision. This condition predominantly affects females in their 20s during childbearing years and can lead to complications such as premature delivery. Effective management includes steroids and antiepileptic drugs, with clexane playing a crucial role in preventing embolisms. A delivery mode may vary based on obstetric factors, and MRI remains the gold standard for diagnosis. Close follow-up is essential for optimal patient outcomes.

Postpartum Quality of Life in Primiparous Women after Normal Vaginal Delivery versus Caesarean Section

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 1027-1045页

作者： Bayan Ahmed Basma Alsayegh Fatema Ahmed zainab Aljufari Department of Obstetrics and Gynecology Salmaniya Medical Complex Manama Kingdom of Bahrain

Background: Studies on either postnatal quality of life in general or studies that compare quality of life in new mothers after different mode of delivery are limited. An investigation on health related quality of life measures in women after different type of delivery showed that women who had vaginal delivery had better health related quality of life compared to those who had caesarean section. however, the best method of delivery, vaginal or caesarean for postpartum quality of life is a difficult question as it is a matter of controversy both from professional’s perspectives and from women’s experience during childbirth. Objective: To compare postpartum quality of life in primiparous women after vaginal delivery versus caesarean section. Methods: Prospective cross-sectional study was conducted at the department of Obstetrics and Gynecology, Salmaniya medical complex in Kingdom of Bahrain. 500 primiparous women who gave birth either vaginally or by cesarean section answered a questionnaire designed to include general information, questions from short form health survey questionnaire (SF-36) and specific questions regarding postnatal related symptoms. Results: Body pain, fatigue, wound pain, headache and backache were significantly higher in cesarean section group as compared to vaginal delivery group (p-value Conclusion: Cesarean delivery has negatively affected the quality of life (QOL) of primiparous women. More studies with larger sample sizes should be conducted to examine the effects of cesarean delivery on QOL in both primiparous and multiparas within a shorter period after delivery. .
