A male patient in his early 60s was referred to the cardiology department for evaluation of a persistent apical ventricular thrombus following a myocardial infarction. Transthoracic echocardiography could not rule out the presence of an apical thrombus, leading to the intravenous administration of the contrast agent sulphur hexafluoride (SonoVue). The patient quickly exhibited signs of anaphylaxis accompanied by haemodynamic shock, resulting in cardiac arrest. He was successfully resuscitated with no significant secondary neurological impairment. According to the European Medicines Agency, anaphylactic reactions to the contrast agent sulphur hexafluoride (SonoVue) occur in approximately 1 in 10 000 cases. To our knowledge, this represents the first case of hypersensitivity to sulphur hexafluoride (SonoVue) confirmed by positive in vitro testing.

Purpose: To evaluate the clinical outcomes of pneumatic retinopexy (PnR) for a recurrent rhegmatogenous retinal detachment (RRD) due to superior retinal breaks following initial vitrectomy for a RRD.
Study Design: Clinical investigations.
Methods: A retrospective study of 82 eyes of 82 patients who underwent vitrectomy by a single surgeon between November 2021 and March 2023.

Optic disc pit maculopathy is a serious complication of congenital optic disc pits, often resulting in significant vision loss due to intraretinal and subretinal fluid accumulation. This case report describes a 35-year-old woman with progressive visual decline in her right eye. Examination revealed optic disc pit maculopathy with marked central foveal thickness (634 μm) and a best-corrected visual acuity of 20/100.

Background: In recent years, the Descemet membrane endothelial keratoplasty (DMEK) has become the standard transplantation procedure for endothelial corneal diseases due to faster visual recovery and lower graft rejection rates compared to penetrating keratoplasty (pKPL). Endothelial corneal decompensation after pKPL is also a possible indication for DMEK. The question is which intraoperative and postoperative aspects need to be considered.

Myocardial contrast echocardiography (MCE) plays an important role in diagnosis of myocardial infarction (MI). However, its accuracy is limited by image quality because microbubble-based MCE produces negative contrast enhancement in the infarcted myocardial tissue. This study aimed to develop nanoscale gas vesicles (GVs) from (hGVs) and GV-expressing genetically engineered (eGVs) and compare their imaging performance with commercial Sonovue in MI rats.

To replace sulfur hexafluoride (SF), a potent greenhouse gas with high global warming potential (GWP) and long lifetime, perfluoroisobutyronitrile (CFN) has emerged as the next-generation insulating gas to advance the development of the power industry, especially gas-insulated equipment. However, most reported synthesis routes for perfluoroisobutyronitrile require expensive reagents or complex procedures and harsh reaction conditions, which are impractical for scalable production and cost reduction for real applications. Herein, we report a three-step synthetic process from perfluoropropylene to perfluoroisobutyronitrile, involving addition with carbonyl fluoride, nucleophilic substitution with ammonia and dehydration.
