The widening of the vestibular dimension of lateral ventricles > 10 mm should be considered a symptom rather than a definitive diagnosis. In fact, fetal ventriculomegaly (VM) is a defect with 'multifaceted' clinical consequences in the child's further neurodevelopment. Isolated fetal ventriculomegaly can cause neurological defects ranging from mild neurodevelopmental delay to severe complications in the form of ongoing palliative care to the death of patients at various developmental periods.

Article Synopsis
  • The study investigated how lead and cadmium levels in follicular fluid affect the redox system and outcomes of assisted reproduction in women with unexplained infertility, specifically those undergoing intracytoplasmic sperm injection (ICSI).
  • It involved 113 patients, excluding those with severe endometriosis or poor ovarian reserve, and analyzed the correlation between heavy metal levels and biochemical markers in the follicular fluid and serum.
  • While lead and cadmium showed a correlation in their concentrations, they didn't have a significant negative impact on the overall ovarian environment or on fertility outcomes, suggesting that adaptive changes in the redox system may mitigate potential harmful effects.

Fetal ventriculomegaly (VM) is a defect of the central nervous system, typically diagnosed during the second-trimester ultrasound in fetuses with an atrial diameter (AD) of >10 mm. Non-isolated ventriculomegaly (NIVM) is heterogeneous in nature, coexisting with additional intracranial and/or extracranial malformations and genetic syndromes, resulting in an unfavorable prognosis for the further development of the child. Both the pregnancy management and counseling are dependent on the findings of combined ultrasound/MRI, genetic testing, and gestational age at diagnosis.

Article Synopsis
  • A significant percentage (31.2%) of patients with chronic spontaneous urticaria (CSU) experience non-skin-related symptoms (NSRS) like recurrent fever, joint/bone/muscle pain, and malaise.
  • These NSRS are linked to various trigger factors such as food and infections, as well as clinical characteristics like sleep disturbances and elevated inflammation markers.
  • Patients with NSRS tend to have worse disease activity, longer duration of CSU, lower quality of life, and a higher likelihood of poor control over their symptoms, highlighting the need for improved management strategies.

Background: Patient-reported outcome measures (PROMs) are validated and standardized tools that complement physician evaluations and guide treatment decisions. They are crucial for monitoring atopic dermatitis (AD) and chronic urticaria (CU) in clinical practice, but there are unmet needs and knowledge gaps regarding their use in clinical practice.

Objecctive: We investigated the global real-world use of AD and CU PROMs in allergology and dermatology clinics as well as their associated local and regional networks.

Introduction: Fetal ventriculomegaly is one of the most commonly diagnosed central nervous system pathologies of the second trimester, occurring with a frequency of 0.3-0.5/1,000 births.

Background: Concern about disease exacerbations and fear of reactions after coronavirus disease 2019 (COVID-19) vaccinations are common in chronic urticaria (CU) patients and may lead to vaccine hesitancy.

Objective: We assessed the frequency and risk factors of CU exacerbation and adverse reactions in CU patients after COVID-19 vaccination.

Methods: COVAC-CU is an international multicenter study of Urticaria Centers of Reference and Excellence (UCAREs) that retrospectively evaluated the effects of COVID-19 vaccination in CU patients aged ≥18 years and vaccinated with ≥1 dose of any COVID-19 vaccine.

Fetal and maternal risks associated with open fetal surgery (OFS) in the management of meningomyelocele (MMC) are considerable and necessitate improvement. A modified technique of hysterotomy (without a uterine stapler) and magnesium-free tocolysis (with Sevoflurane as the only uterine muscle relaxant) was implemented in our new magnesium-free tocolysis and classical hysterotomy (MgFTCH) protocol. The aim of the study was to assess the introduction of the MgFTCH protocol in reducing maternal and fetal complications.

Spina bifida aperta (SBA), with (myelomeningocele) or without (myeloschisis) a hernia sack, is the most common congenital defect of the central nervous system. Prenatal surgical closure of SBA lowers the risk for developing shunt-dependent hydrocephalus, which offers a chance at improved motor, urinary, and gastrointestinal function. A total of 96 patients who had undergone open surgery prenatal repair for SBA were analyzed.

Open spina bifida is one of the most common congenital defects of the central nervous system. Open fetal surgery, which is one of the available therapeutic options, remains the gold standard for prenatal repairs. Fetoscopic closure may lower the number of maternal complications associated with open fetal surgery.

Objectives: The aim of the study was to determine the effectiveness of an alternative method of open fetal surgery to prevent severe unfavorable prenatal events, both for the mother and the fetus.

Material And Methods: In this study, the previously published results for a cohort of 46 patients, who had undergone intrauterine myelomeningocele repair (IUMR) at our Center by 2014, constituted the retrospective control group (CG). The MOMS protocol had been applied for hysterotomy, with an automatic uterine stapling device.

Introduction: The main aim of the fetal surgery of myelomeningocele (MMC) is the improvement in prognosis for children with this defect and at the same time high safety of the procedure for mother and fetus.

Objective: The aim of the study was to determine the effectiveness of alternative hysterotomy technique for fetal surgery of MMC in prevention of essential perinatal complications.

Methods: Forty-nine pregnant women diagnosed with fetal MMC (fMMC) who underwent classic hysterotomy without the use of stapler formed the study cohort.

Article Synopsis
  • - The study aimed to evaluate how increased experience of a surgical team in fetal myelomeningocele (fMMC) repair impacts maternal and fetal/neonatal outcomes over different time periods.
  • - Researchers compared outcomes from two cohorts: an early period (2005-2011) and a current period (2012-2015), alongside a randomized study involving 78 patients, finding low maternal morbidity and a significant drop in preterm labor rates.
  • - The increased experience of the surgical team led to improved outcomes, notably a decrease in iatrogenic preterm labor from 34.1% to 23.9%, while the rate of hindbrain herniation reduction remained similar across the cohorts.

Objective: This study presented outcomes of classical hysterotomy with modified antiprostaglandin therapy for intrauterine repair of foetal myelomeningocele (fMMC) performed in a single perinatal centre.

Study Design: Forty-nine pregnant women diagnosed with fMMC underwent classic hysterotomy with anti-prostaglandin management, complete amniotic fluid replacement and high dose indomethacin application.

Results: The average gestational age (GA) at delivery was 34.

Myelomeningocele (MMC) is the most frequent congenital defect of the central nervous system for which there is no satisfactory alternative to postnatal treatment. On the contrary prenatal MMC surgery is conducting before birth and is aimed at protecting from Chiari II malformation. The main goal of fetal MMC repair is to improve development and life quality of children with Chiari II malformation.

Objective: The aim of this study was a comparison of the outcomes of intrauterine myelomeningocele (MMC) repairs (IUMR) in type II Chiari malformation (II CM) fetuses with clinical data of newborns and infants operated on postnatally.

Methods: The study group (SG) comprised 46 pregnant women whose type II CM children underwent IUMR, while 47 pregnant women whose type II CM children were operated on postnatally constituted the control group (CG). A total of 24 SG and 20 CG patients reached the endpoint of the study.
