Primary epithelioid angiosarcoma of the thyroid: A case report.

Angiosarcoma of the thyroid is a rare and aggressive primary malignant tumour of the thyroid. We report the case of a 69-year-old woman who presented with a red and sore skin area at the right-anterior region of the neck. Ultrasound examination and computed tomography scan showed a non-homogeneous mass in the right thyroid lobe. Fine needle aspiration cytology was suggestive of atypical vascular proliferation and so the patient underwent right thyroid lobectomy. The specimen measured 6 × 5 × 2.5 cm, and a reddish nodule was found, including a whitish central area of maximum 4 cm in diameter. Immunohistochemistry showed CD31 and ERG positivity, while thyroglobulin, calcitonin and TTF-1 expression were negative, indicating a diagnosis of angiosarcoma.

Effectiveness of the flash glucose monitoring system in preventing severe hypoglycemic episodes and in improving glucose metrics and quality of life in subjects with type 1 diabetes at high risk of acute diabetes complications.

AIMS: To assess the effectiveness of the intermittent-scanned continuous glucose monitoring (isCGM) system in preventing severe hypoglycemic episodes and in improving glucose parameters and quality of life. METHODS: Four hundred T1D individuals were enrolled in a prospective real-word study with an intermittently scanned continuous glucose monitoring device during the 12-months follow-up. The primary endpoint was the incidence of severe hypoglycemic events. RESULTS: 82% of subjects were naïve to the use of the device (group A) and 18% were already wearing the system (group B). The cumulative incidence of severe hypoglycemia (SH) at 12 months was 12.06 per 100 person-year (95% CI: 8.35-16.85) in group A and 10.14 (95% CI: 4.08-20.90) in group B without inter-group differences. In group A there was a significant decrease in SH at 12 months compared to 3 months period (p = 0.005). Time in glucose range significantly increased in both groups accompanied with a significant decrease in glucose variability. HbA1c showed a progressive significant time-dependent decrease in group A. The use of the device significantly improved the perceived quality of life. CONCLUSION: This study confirmed the effectiveness of the isCGM in reducing hypoglycemic risk without glucose deterioration, with potential benefits on adverse outcomes in T1D individuals.
