Background And Objectives: Fetal intra-abdominal umbilical vein (FIUV) varix-a focal dilatation of the umbilical vein-is an uncommon entity. Outcome varies from spontaneous resolution to fetal death. We describe here the experience of our center with this perplexing entity.

Methods: Case series review of seven cases of isolated FIUV treated in a tertiary care center from 2000 to 2003.

Results: We describe seven cases of isolated FIUV varix with varying natural history, follow-up strategies, and fetal outcome. In one of the cases, intrauterine fetal demise occurred despite close follow-up.

Conclusions: We suggest that the course of FIUV is unpredictable, with a high fetal mortality rate. Close fetal monitoring with early delivery at 34 weeks' gestation should be advocated.

Introduction: Perinatal management of gastroschisis remains a subject of substantial research. Current models, including teratogenic, genetic, and surgical approaches, often fail to accurately replicate gastroschisis, exhibiting limitations such as inaccurate phenotyping, low success rates, high mortality, lack of scientific validation, and significant technical challenges. Refined disease models are essential for improving the understanding of GS.

Introduction: The urachus is a fetal canal that connects the allantois to the bladder and typically obliterates by the 6th month of gestation. Failure of the urachus to obliterate can result in urachal anomalies, which, in rare cases, may undergo malignant transformation.

Case Presentation: We present a case of a 13-year-old female who experienced hematuria, dysuria, and abdominal pain persisting for over 4 months.

Spontaneous hepatic rupture is a rare complication that occurs in pregnant mothers with HELLP syndrome, or preeclampsia with severe features, or eclampsia. The most common symptom of hepatic rupture/hematoma is right upper quadrant pain or epigastric pain, which is similar to the presentation of preeclampsia with severe features. Therefore, the absence of specific signs and symptoms leads to a diagnostic dilemma and a delay in management.

Uterine rupture with induction using misoprostol for intrauterine foetal death in the second trimester: A case report.

Uterine rupture is a well-known, life-threatening complication of misoprostol use; the incidence is remarkably low. Herein, we report what seems to be the first documented case of uterine rupture following induction of labour for intrauterine foetal death in the second trimester without a uterine scar. A 40-year-old woman with no history of caesarean section or uterine surgery presented with mild lower abdominal pain and mild genital bleeding.

Article Synopsis
  • - Omphalocele is a rare congenital defect, affecting 1 in 5,000 to 10,000 newborns, where abdominal organs push through a gap at the base of the umbilical cord, requiring complex surgical treatment to prevent serious complications.
  • - A case study illustrates a female newborn with a large omphalocele who underwent an urgent cesarean delivery; a staged surgical approach was used, involving a silo for organ reduction and closure with absorbable sutures and biologic mesh.
  • - The case emphasizes the importance of coordinated care among pediatric surgeons and personalized treatment plans, as the patient is now thriving six months post-surgery with no complications.
