BACKGROUND/AIM: Second primary tumors (SPTs) often occur, either synchronous or metachronous. Struma ovarii is a rare ovarian tumor represented by thyroid tissue in the ovary. Among other factors, production of thyroid hormones by the tumor or a shared genetic predisposition can further influence the development of SPTs. The occurrence of SPT, either synchronous or metachronous, following a long follow-up, has never been considered extensively. PATIENTS AND METHODS: We analyzed the Surveillance, Epidemiology, and End Results (SEER) database from 1973 to 2011 to follow-up all the cases of malignant struma ovarii in an effort of calculate the occurrence of SPTs in this cohort of patients...

BACKGROUND/AIM: The left atrial appendage (LAA) is the most typical origin for a cardioembolic thrombusins' stroke etiology. Although transesophageal echocardiography (TEE) is widely used, this technique encounters difficulties in differentiating solid thrombus from circulatory stasis/spontaneous echo contrast (SEC). We assessed whether cardiac computed tomography (cCT) could more accurately detect LAA thrombi. MATERIALS AND METHODS: A total of 102 patients with suspected acute cardioembolic stroke/ transient ischemic attack (TIA) without chronic atrial fibrillation underwent arterial and venous phase cCT and TEE...

Ultraviolet B (UVB), with a wavelength of 280-320 nm, represents one of the most important environmental factors for skin disorders, including sunburn, hyperpigmentation, solar keratosis, solar elastosis and skin cancer. Therefore, protection against excessive UVA-induced damage is useful for prevention of sunburn and other human diseases. Baicalin, a major component of traditional Chinese medicine Scutellaria baicalensis, has been reported to possess antioxidant and cytostatic capacities. In this study, we examined whether baicalin is also capable of protecting human keratinocytes from UVB irradiation...
