AI Article Synopsis

  • Posterior reversible encephalopathy syndrome (PRES) is a rare and reversible neurological condition often linked to specific cancer treatments, particularly targeted therapies.
  • A case study details a 44-year-old woman with metastatic colon cancer who developed PRES after one month of treatment with the VEGFR inhibitor fruquintinib, marking it as the first reported case of this condition related to the drug.
  • The patient's neurological function improved after stopping the medication for a week, but worsened again when she resumed a lower dose, highlighting the need for doctors to be aware of PRES when prescribing fruquintinib.

Article Abstract

Posterior reversible encephalopathy syndrome (PRES) is a rare, reversible neurological disease that is frequently associated with the use of targeted therapy agents. In this case study, we examine the development of posterior reversible encephalopathy syndrome (PRES) in a 44-year-old woman with metastatic colon cancer following 1 month of treatment with the vascular endothelial growth factor receptor (VEGFR) inhibitor, fruquintinib. The occurrence of PRES after 1 month of VEGFR inhibitor administration is a common phenomenon. However, it is noteworthy that this is the first reported case of PRES associated with fruquintinib. The patient's neurological function improved upon discontinuing the drug for a week, but worsening was observed following a lower-dose fruquintinib treatment. This patient's experience highlights the potential for neurological deterioration in those treated with fruquintinib, prompting physicians to consider the possibility of PRES. Notably, this may be the first reported case linking fruquintinib to the syndrome, underscoring the importance of recognizing the association between PRES and fruquintinib.

Nowadays, experimental research advances in condensed matter physics are deep-rooted in the development and manipulation of nanomaterials, making it essential to explore the fundamental properties of materials that are candidates for nanotechnology. In this work, we study the dependence of the molybdenum disulfide (MoS2) Raman modes on the sample temperature and on the excitation laser power. From the correlation between these two sets of measurements, we determine the planar thermal conductivity of MoSmonolayers, bilayers, trilayers, four layers, seven layers, and eight layers.

Introduction: The hemolysis-elevated liver enzymes-low platelet counts (HELLP) syndrome and posterior reversible encephalopathy syndrome (PRES) are rare conditions that can complicate pregnancy and the early postpartum period. Although both are closely related to hypertensive pregnancy disorders, their association is rarely described, so the outcome of these patients remains unknown. We present a case report of PRES associated with HELLP syndrome and a review of all previously published cases, including demographic characteristics, clinical presentation, treatment, and outcome.

Objective: In laparoscopic surgery, initial entry into the abdomen becomes more risky in patients with a history of abdominal surgery. In such cases, initial entry is usually performed with a Veress needle via Palmer's point (PP). However, it is associated with an increased failure rate, especially in obese patients.

Objectives: Eclampsia remains a principal cause of maternal mortality, especially in low- and middle-income countries. The frequent association with Posterior Reversible Encephalopathy Syndrome (PRES) underscores the critical role of neuroimaging in clinical assessment. We aimed to evaluate tomographic findings in women with eclampsia and analyze clinical factors associated with these abnormalities.

Unlabelled: Haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a poorly understood, life-threatening multisystemic condition related to pregnancy with a rapid onset, typically observed in patients with severe pre-eclampsia. Various mechanisms may lead to diffuse endothelial damage associated with HELLP and possible brain involvement. A comprehensive review of PubMed, Embase and Cochrane databases was conducted to examine the clinical, laboratory and radiological features associated with postpartum HELLP syndrome, particularly its potential association with posterior reversible encephalopathy syndrome (PRES).
