Evaluation of the optic nerve using strain and shear-wave elastography in pre-eclampsia

INAL, MIKAIL/0000-0003-0642-7913; Gokcinar, Nesrin Buyuktortop/0000-0001-7795-5188WOS: 000484770700015PubMed: 31301764AIM: To investigate the utility of strain elastography and shear-wave elastography for assessing optic nerve involvement in pre-eclampsia. MATERIAL AND METHODS: A total of 120 eyes were evaluated in 60 cases consisting of 30 participants in the pre-eclamptic and 30 participants in the non-pre-eclamptic pregnant patient group. The findings of strain and shear-wave elastography, grey-scale sonography, and optical coherence tomography were compared between the groups. RESULTS: There was a statistically significant difference for the average shear-wave elastography values between groups (17.6 +/- 4.1 and 9.4 +/- 2 kPa, p0.05). CONCLUSION: Stiffness of the optic nerve was greater in patients with pre-eclampsia in the study. Elasticity changes in the optic nerve may be generally attributed to microvascular and biomechanical changes secondary to increased hypertension in pre-eclamptic patients. Elastography could be used as assistive diagnostic techniques to evaluate the optic nerve structure changes in pre-eclampsia. (C) 2019 The Royal College of Radiologists. Published by Elsevier Ltd.

Perinatology clinic in the coronavirus disease-2019 pandemic: What harms, often teaches

Compartmental models simplify the mathematical modeling of infectious diseases based on reported cases. In the absence of precautions, personal protective equipment, quarantine and social distancing, a Susceptible–Exposed–Infectious–Recovered (SuEIR) model with Unscented Kalman Filter for coronavirus disease-19 (COVID-19) Forecasts in Turkey has revealed 174 641 infected people on August 15, 2020, whilst the reported case was 12 216. Through numerical experiments, the effects of quarantine, social distancing, and COVID-19 testing on the dynamics of the outbreak varies. We herein present the documentation of the work in a perinatology clinic during COVID-19 pandemic to find the reflection in a pandemic hospital as even in the pandemic, pregnancy complications and fetal diagnosis/therapy are time-sensitive and cannot be delayed. During the prevention of the horizontal transmission to the health-care workers (HCWs), testing all pregnant women with nasopharyngeal/oropharyngeal swabs for severe acute respiratory syndrome coronavirus (SARS-COV-2) undergoing birth, ultrasound examinations, invasive procedures appear to be the gold standard so that appropriate precautions can be taken if the screen is positive. Though it is logical, it may be incompatible with a busy obstetric practise as a pending polymerase chain reaction (PCR) result should never delay any emergent procedure
