F-FDG PET/CT Imaging of Metastatic Testicular Choriocarcinoma Mimicking Gastric Cancer which Initial Symptom is Melena.

Gastric metastasis of choriocarcinoma is rarely reported in the literature. This case report presents the case of multiple metastatic testicular choriocarcinoma mimicking gastric cancer, with melena as the initial symptom. In this case, fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) showed that the testis was the primary focus.

New Evidence for Causal Central Mechanism of Hyperglycemia in Subarachnoid Hemorrhage Secondary to Ischemic Degenerative Disruption of Circuitry Among Insular Cortex, Nodose Ganglion, and Pancreas: Experimental Study.

Introduction: Although hyperglycemia is a serious complication of subarachnoid hemorrhage, its pathophysiologic mechanism based on neural circuitry has not been known.

Materials And Methods: Twenty-five rabbits were divided into 4 groups, with 5 in the control group. The SHAM and study groups received 1 mL saline and 1 mL autologous arterial blood into the sylvian cisterna, respectively.
