Radiation on Earth or in Space: What Does It Change?

Int J Mol Sci 2021 Apr 3;22(7). Epub 2021 Apr 3.

Inserm, U1296 Unit, «Radiation: Defense, Health and Environment», Centre Léon-Bérard, 28, Rue Laennec, 69008 Lyon, France.

After having been an instrument of the Cold War, space exploration has become a major technological, scientific and societal challenge for a number of countries. With new projects to return to the Moon and go to Mars, radiobiologists have been called upon to better assess the risks linked to exposure to radiation emitted from space (IRS), one of the major hazards for astronauts. To this aim, a major task is to identify the specificities of the different sources of IRS that concern astronauts. Read More

Ophthalmology, 12 de Octubre Hospital, Complutense University, Madrid, ESP.

A non-traumatic or spontaneous orbital hemorrhage (NTOH) is usually caused by the presence of an orbital mass, an inflammation, an infection, a bleeding disorder or those called idiopathic. This entity usually affects elderly adults and some risk factors can be identified. The NTOH normally acts like a benign and self-limited process, but attending to its anatomical pattern, may need specific management. Read More

Br J Oral Maxillofac Surg 2020 11 13;58(9):1091-1096. Epub 2020 Jun 13.

Byers Eye Institute, Stanford University, Palo Alto, CA; Stanford University Hospital, Stanford, CA. Electronic address:

Retrobulbar haemorrhage (RBH) is a potentially blinding consequence of craniofacial trauma, but timely ophthalmic evaluation is difficult to obtain in some settings and clear standards for canthotomy/cantholysis are lacking. We have sought to develop an algorithm to identify vision-threatening traumatic RBH that requires emergent decompression. We retrospectively reviewed 42 consecutive consultations for RBH at a level-one trauma centre. Read More

Orbital infarction syndrome after mechanical thrombectomy in acute ischaemic stroke.

BMJ Case Rep 2020 May 5;13(5). Epub 2020 May 5.

Radiology, Hospital Clinico Universitario San Carlos, Madrid, Spain.

Orbital infarction syndrome (OIS) encompasses the ischaemic infarction of all intraorbital and intraocular structures (optic nerve, extraocular muscles and orbital fat) which leads to a painful loss of visual acuity, ophthalmoparesis, chemosis, proptosis and ptosis. The rich anastomotic orbital vascularisation from internal carotid artery (ICA) and external carotid artery makes this disorder a rare cause of visual loss in stroke patients. We describe a case of a woman who suffered an acute occlusion of her right ICA and developed an OIS after mechanical thrombectomy. Read More

Acute radiation risk assessment and mitigation strategies in near future exploration spaceflights.

Life Sci Space Res (Amst) 2020 Feb 31;24:25-33. Epub 2019 Oct 31.

NASA Johnson Space Center, Houston TX, United States.

As more exploration spaceflights are planned to travel beyond the protective Earth magnetosphere to deep space destinations, acute health risks due to possible high radiation doses during severe Solar Particle Events (SPEs) are of greater concern to mission planners and management teams. It is expected that some degree of Acute Radiation Syndromes (ARS) symptoms may be observed, but the specific list of health risks that are relevant to exploration missions has been ambiguous and debatable in the past. This mini-review gives a brief summary of the features of radiation exposure if astronauts encounter severe SPEs beyond Low Earth Orbit (LEO), the evidence of ARS radiobiological studies at exposure levels close to recommended limits, and the shortcomings of previous dose projection approaches for ARS risk assessment.

University of Minnesota Departments of Ophthalmology and Visual Neurosciences and Otolaryngology, University of California, San Diego, California, USA.

Switch/sucrose non-fermentable-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1 (SMARCB1), also known as integrase interactor 1-deficient sinonasal carcinoma, is a rare entity that was first described in 2014. Since then, there have been 39 cases published in the literature, with basaloid or plasmacytoid/rhabdoid morphology being the most common pathological subtype. We report a patient with switch/sucrose non-fermentable-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1 (integrase interactor 1)-deficient sinonasal carcinoma who had permanent vision loss after valsalva-induced acute hemorrhage and resultant orbital compartment syndrome.

Emergency Department, Birmingham Children's Hospital, Birmingham, UK.

Introduction: Acute retrobulbar haemorrhage (RBH) with orbital compartment syndrome is a sight-threatening ophthalmic emergency requiring treatment with lateral canthotomy and cantholysis (LC/C). However, such cases may present to non-ophthalmic emergency departments (ED) out-of-hours, when specialist intervention is not readily available. We completed a survey of ED physicians to explore experiences of RBH and confidence in undertaking LC/C. Read More

Department of Clinical Sciences, Companion and Equine Animals, Ophthalmology, University of Liège, Quartier Vallée 2, Avenue de Cureghem 3, 4000 Liège, Belgium.

Orbital compartment syndrome (OCS) is described in humans as an acute rise in intraorbital pressure following a severe and rapidly evolving orbital affection. It includes orbital oedema, haemorrhage or infection causing a marked reduction in local blood perfusion, and severely affecting the orbital neurovascular structures. If not promptly recognised and treated, it results in irreversible blindness. Read More
