Hemolytic disease is a common cause of fetal morbidity and mortality. The anti-M blood cell alloantibodies are one of the most severe causes of fetal anemia and intrauterine death. Since no standard treatment method has been established for pregnant women, the management of this pathology is through conventional methods used for treating Rh blood-type alloimmunization. For the first time, we report a unique case wherein a pregnant woman who had intrauterine fetal death in two previous pregnancies with very low titers of anti-M antibodies had negative effects during very early pregnancy, which were successfully managed in her third pregnancy with a novel protocol...

Introduction  Group B streptococcus (GBS) is the leading cause of bacterial sepsis and meningitis in neonates worldwide, but brain abscess secondary to GBS is extremely rare. While temporal brain abscesses have been described as a sequelae of otogenic infections in children and adults, such a presentation has not been described in neonates. Case Description  An 8-day-old female infant presented with a fever and irritability along with bilateral purulent otorrhea. Maternal GBS screening was negative, but the delivery was complicated by chorioamnionitis...

Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is a rare condition characterized by microangiopathic hemolytic anemia and kidney injury from thrombotic microangiopathy. P-aHUS occurs in approximately 1 in 25,000 pregnancies and is strongly related to complement dysregulation and pregnancy-related disorders, such as preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome, resulting in adverse perinatal and fetal outcomes. Complement dysregulation in P-aHUS is commonly attributed to genetic mutations or autoantibodies affecting complement factors, including CFH , CFI , and MCP...

Maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can affect placental function, but the possibility of intrauterine transmission has been debated. Several authors have published inclusion criteria for vertical transmission, but few reports exist that are able to meet the suggested requirements. Despite the fact that the majority of fetuses born to infected mothers do well, others become critically ill. We present a case of likely intrauterine transmission of a neonate born to a mother who was recently symptomatic with a positive SARS CoV-2 polymerase chain reaction (PCR)...

Uterine leiomyomas are common benign smooth muscle tumors that often occur during the reproductive years. Although many cases may not result in significant complications, negative pregnancy outcomes have been associated with the size and location of the fibroids. Degeneration of fibroids can occur as early as the late first trimester when they undergo significant volumetric growth, contributing to pain during pregnancy. While myomectomy is typically avoided during pregnancy, conservative management with anti-inflammatory medications may be effective...

Uterine leiomyomata are associated with many pregnancy complications and will likely become increasingly common as the average age of childbearing increases. We describe a case of an obstructed delivery by a large fibroid. A 37-year-old G2P1001 with a 10-cm anterior, lower uterine segment fibroid presented for labor induction. Labor was complicated by arrest of descent due to suspected obstruction of the fetal body by the fibroid after descent of the fetal head, and delivery during cesarean section was complicated by apparent interlocking of the fetal mentum with the fibroid...

Background  Conventional buprenorphine inductions require patients to abstain from full agonist opioids until they experience mild-to-moderate opioid withdrawal. We described a successful buprenorphine induction case in a pregnant patient using microdosing, which avoided withdrawal symptoms. Case Presentation  The patient is a 29-year-old G2P1001 at 18 2/7 weeks of gestation, who desired a switch from methadone to buprenorphine to minimize neonatal opioid withdrawal syndrome (NOWS), which complicated her last pregnancy...

Multisystem inflammatory syndrome in children (MIS-C), a new condition related to coronavirus disease 2019 (COVID-19) in the pediatric population, was recognized by physicians in the United Kingdom in April 2020. Given those up to the age of 21 years can be affected, pregnant adolescents and young adults are susceptible. However, there is scant information on how MIS-C may affect pregnancy and whether the presentation differs in the pregnant population. We report a case of a pregnant adolescent with COVID-19 and MIS-C with a favorable outcome...

Cornelia de Lange's syndrome (CDLS) is a multisystem genetic syndrome characterized by well-defined physical, intellectual, and behavioral characteristics. The diagnosis of CDLS is typically done clinically after birth; however, recent studies have demonstrated the ability to use prenatal ultrasound and whole-exome sequencing to diagnose CDLS prenatally. Here we present a prenatal case in which multiple fetal anomalies were identified on ultrasound at 20 weeks of gestation. Use of whole-exome sequencing allowed for successful diagnosis of CDLS in this fetus prenatally...

Vitamin K deficiency bleeding (VKDB) in neonates is a significant disorder that causes skin, gastrointestinal, and intracranial hemorrhaging. Early-onset VKDB occurs within 24 hours of birth, and its prognosis is poor due to severe hemorrhage. The causes of early-onset VKDB include maternal intake of warfarin and anticoagulants, and maternal vitamin K deficiency. We report the case of a neonate with early-onset VKDB born to a mother with Crohn's disease. The neonate developed severe cerebellar hemorrhage on the day of birth and subsequent noncommunicating hydrocephalus requiring a ventriculoperitoneal shunt...

Drug-induced liver injury (DILI) is a common cause of transaminitis in pregnancy. A 34-year-old G3P2012 presented 3 weeks postpartum for preeclampsia with severe features. After receiving acute antihypertensive medications, she was discharged home with labetalol. She presented 5 months later with general malaise, scleral icterus, nausea, and mild right upper quadrant pain and found to have significantly elevated transaminitis. She had a negative infectious, autoimmune, biliary, and steatohepatitis workup. A liver biopsy was performed supporting the diagnosis of DILI...

Neuroendocrine small cell cervical carcinoma is an aggressive cancer which accounts for approximately 1 to 3% of all cervical neoplasms. Therapy must be altered in pregnancy to optimize maternal-fetal outcomes. A 39-year-old woman presented for a routine prenatal visit and was noted to have a grossly abnormal cervix. Cervical biopsies confirmed small cell carcinoma. At 19 weeks' gestation, chemotherapy was initiated. The patient delivered at 34 weeks' gestation to initiate radiation therapy. Six months later, she was diagnosed with metastatic disease and died from cancer complications...
