A Mysterious Cause of Coagulopathy With Bleeding Diathesis.

Vitamin K is essential to produce functional vitamin K-dependent coagulation factors (prothrombin, factors VII, IX, and X). Vitamin K antagonists inhibit the normal activation of these factors, leading to bleeding manifestations of variable severity. Long-acting vitamin K antagonists or superwarfarins were developed as rodenticides and have a significantly longer half-life and greater potency when compared to warfarin.

Lung Adenocarcinoma and Peripheral Blood Eosinophilia.

There are many causes of peripheral blood eosinophilia (PBE), including allergic, infectious, rheumatic, and hematologic disorders. Solid tumor cancers, such as lung cancer, can also cause PBE, and although rare, being diagnosed with PBE in this way is associated with a worse prognosis than for lung cancer patients without PBE. Additionally, some cancer patients develop PBE when receiving treatment with immune checkpoint inhibitors (ICIs).

Giant Cell Arteritis Presenting as Multiple Ischaemic Strokes: A Successful case of Endovascular Treatment.

Unlabelled: Giant cell arteritis (GCA) may manifest with aggressive intracranial stenosis resistant to medical therapy, and patients may develop refractory neurologic deficits and cerebral infarcts, making GCA a life-threatening condition. We report the case of a 68-year-old woman recently diagnosed with GCA, medicated with prednisolone 60 mg daily. Two weeks later, the patient was admitted to our Stroke Unit after a sudden episode of global aphasia.
