Post-COVID-19 Thoracic Aortic Rupture with an Unforeseen Spinal Epidural Hematoma.

The importance of prompt diagnosis and early stenting of an aortic rupture cannot be overemphasized. We present a case of thoracic aortic rupture in a middle-aged gentleman who had recently suffered coronavirus disease 2019. The case was further complicated by the development of an unexpected spinal epidural hematoma.

Blind Obturator Bypass-A Scope for Improvisation.

Extra-anatomical femoral bypass in hostile condition such as an infected femoral artery pseudoaneurysm has commonly been performed by tunneling a graft via the obturator foramen. However, the rarity of such cases and very selective indications for the obturator bypass procedure (OBP) has resulted in a paucity of improvisation in this surgery. The aim of this article is to briefly discuss the difficulties faced by our team when recently performing an OBP and to highlight possible innovative approaches by introducing a laparoscope to make the blind OBP safer and more precise.

Tumebacillus permanentifrigoris gen. nov., sp. nov., an aerobic, spore-forming bacterium isolated from Canadian high Arctic permafrost.

A Gram-positive, aerobic, rod-shaped bacterium (strain Eur1 9.5(T)) was isolated from a 9-m-deep permafrost sample from the Canadian high Arctic. Strain Eur1 9.

A regioselective cyanohydration of steroidal 17-ketones and the configuration of the resulted cyanohydrins.

Cyanohydration of some 17-keto steroids with 4-en-3-one or 1,4-dien-3-one unit showed high regioselectivity to give 17-cyanohydrins with high yields when the reaction was carried out under acetone cyanohydrin/K2CO3 in aq. MeOH. The crystal X-ray exhibited the configuration of resulted cyanohydrins were depended on the structure of substrates.
