[Loss of an eye as a result of an odontogenic infection].

Ned Tijdschr Tandheelkd 2021 Jun;128(6):311-316

A 50-year-old woman presented at the outpatient clinic of the department of oral and maxillofacial surgery with a severe swelling around the left eye 1 week after removal of the second molar in the upper jaw. Despite administration of antibiotics 2 days after the removal of the molar because of periorbital swelling, the inflammation spread to the intraorbital space with eventual loss of the left eye. Timely recognition of the symptoms of (the onset of) an orbital infection after dental treatment and immediate referral to an oral and maxillofacial surgeon and/or ophthalmologist for adequate treatment can be vision-saving.

Superior ophthalmic vein thrombosis secondary to COVID-19: an index case.

Radiol Case Rep 2021 May 3;16(5):1138-1143. Epub 2021 Mar 3.

Department of Radiology, Royal Free Hospital, Royal Free London NHS Foundation Trust, Pond St, Hampstead, London, NW3 2QG.

Superior ophthalmic vein thrombosis is a very rare condition, known to have a profound negative impact on vision and eye movement function and is usually associated with orbital infections, inflammation, tumors, or carotid cavernous fistulae. There is an increased risk of arterial and venous thrombosis associated with COVID-19, the presence of which is related to a significantly increased risk of mortality. We report an index case of superior ophthalmic vein thrombosis in a 61-year-old male patient who was diagnosed with COVID-19 pneumonitis and a concomitant saddle pulmonary embolus. Read More

Computational Analysis Reveals a Critical Point Mutation in the -Terminal Region of the Signaling Lymphocytic Activation Molecule Responsible for the Cross-Species Infection with Canine Distemper Virus.

Molecules 2021 Feb 26;26(5). Epub 2021 Feb 26.

Department of Virology 3, National Institute of Infectious Diseases (NIID), Musashimurayama 208-0011, Japan.

Infection of hosts by morbilliviruses is facilitated by the interaction between viral hemagglutinin (H-protein) and the signaling lymphocytic activation molecule (SLAM). Recently, the functional importance of the -terminal region of human SLAM as a measles virus receptor was demonstrated. However, the functional roles of this region in the infection process by other morbilliviruses and host range determination remain unknown, partly because this region is highly flexible, which has hampered accurate structure determination of this region by X-ray crystallography.
