Symptomatic venous thromboembolism after transsphenoidal surgery in Cushing's disease: incidence and risk factors.

Purpose: Cushing's Disease (CD) has been linked to increased venous thromboembolism (VTE) risk. This study investigates the incidence and risk factors of postoperative VTE in patients undergoing transsphenoidal surgery (TSS) for CD.

Methods: This retrospective study analyzed patients with CD and non-functioning pituitary adenomas (NFPAs) who underwent TSS at Massachusetts General Hospital from 2005 to 2019.

Autoimmune Disorders Associated With Surgical Remission of Cushing's Disease : A Cohort Study.

Background: Glucocorticoids suppress inflammation. Autoimmune disease may occur after remission of Cushing's disease (CD). However, the development of autoimmune disease in this context is not well described.

The Upregulation of Molecules Related to Tumor Immune Escape in Human Pituitary Adenomas.

Human pituitary adenomas are one of the most common intracranial neoplasms. Although most of these tumors are benign and can be treated medically or by transsphenoidal surgery, a subset of these tumors are fast-growing, aggressive, recur, and remain a therapeutic dilemma. Because antibodies against immune checkpoint receptors PD-1 and CLTA-4 are now routinely used for cancer treatment, we quantified the expression of mRNA coding for PD-1, CLTA-4, and their ligands, PD-L1, PD-L2, CD80, and CD86 in human pituitary adenomas and normal pituitary glands, with the ultimate goal of exploiting immune checkpoint therapy in aggressive pituitary adenomas.

[The efficiency of cilostazol for cerebral vasospasm following subarachnoid hemorrhage].

Delayed ischemic deficit following subarachnoid hemorrhage(SAH)is a major source of morbidity and mortality after rupture of an intracranial aneurysm. Once symptomatic cerebral vasospasm has occured, available treatments do not provide good outcomes for all patients. Symptomatic vasospasm results in serious sequelae for 10-15% of patients and the etiology and pathogenesis remain unclear.

[A case of meningeal melanocytoma in the cerebellopontine angle].

Meningeal melanocytomas are uncommon intracranial tumors and extremely rare in the cerebellopontine angle (CPA). The tumors are generally considered to be benign because they lack malignant features in histological examination, but several literatures describe malignant behavior of the tumors such as high frequency of local recurrence, malignant transformation with leptomeningeal seeding. We describe a case of meningeal melanocytoma in the CPA and discuss the features of the tumor.
