GPS evidence for northward motion of the Sinai Block: Implications for E. Mediterranean tectonics

GPS survey sites in the Sinai Peninsula show northerly motion relative to Africa (Nubia) at 1.4 ± 0.8 mm/yr north and 0.4 ± 0.8 mm/yr west. Continuous IGS GPS sites in Israel, west of the Dead Sea fault show a similar northerly sense of motion relativ

Thyrotropin/Thyroglobulin ratio in combination with thyroid u/s to assess malignancy risk stratification of thyroid nodules

Objective: we aimed to asses if thyrotropin/thyroglobulin ratio has a significant value in detection of malignant thyroid nodules. Design: Retrospective analysis. Material and Methods: This study included finally 100 subject collected as outpatient’s endocrinology clinic of ALHuessine university hospital or admitted at oncology institute of Tanta. Patients who had history of thyroid diseases or surgery, those with abnormal levels of anti- thyroglobulin antibodies, cases without simultaneous measurement of serum anti Tg., with history of current use of thyroid hormone replacement therapy were excluded from this study. Clinico pathological features, as well as serumTSH, Tg, and TSH/Tg were compared between histopathologically benign and malignant groups. Results: Data related to 100 subjects (40%) normal  and 60(60%) patients  with thyroid nodules were analyzed, 30 patients (50%) were malignant thyroid nodules and 30 patients (50%) were benign.The malignant patients exhibited significantly higher TSH, TSH/Tg, , and a lower Tg compared to the benign patients (p<0.05 for each). Conclusion: Preoperative TSH/Tg could be used as a predictive marker for differ-entiating between benign and malignant thyroid nodules
