Round spermatid injection (ROSI) into oocytes offers men with non-obstructive azoospermia (NOA) the opportunity to have biological offspring in cases where mature spermatozoa are not detected. However, the clinical outcomes of ROSI remains poor. This study compares the outcomes of ROSI with intracytoplasmic sperm injection (ICSI) and investigates the effect of hormonal pretreatment. ⋯ ROSI demonstrated fertilization and implantation rates comparable to those of ICSI for male patient with NOA undergoing testicular sperm extraction surgery. Further studies evaluating the effect of anastrozole administration on ROSI outcomes are warrant.

Metastatic melanoma of the ampulla of Vater is rare. The purpose of this study was to summarize the characteristics and outcomes of metastatic melanoma in the ampulla of Vater and highlight the impact of surgery on the prognosis of patients with metastatic melanoma. ⋯ Given the availability of effective systemic therapies, metastatic melanoma of the ampulla of Vater does not necessarily preclude major surgeries.

Incidence of Concurrent Cerebral Desaturation and Electroencephalographic Burst Suppression in Cardiac Surgery Patients.
Increased intraoperative electroencephalographic (EEG) burst suppression is associated with postoperative delirium. Cerebral desaturation is considered as one of the factors associated with burst suppression. Our study investigates the association between cerebral desaturation and burst suppression by analyzing their concurrence. Additionally, we aim to examine their association with cardiac surgical phases to identify potential for targeted interventions. ⋯ Cerebral desaturation is associated with intraoperative burst suppression during cardiac surgery, most significantly during CPB, especially during the period between the removal of the aortic cross-clamp and end of CPB. Further exploration with simultaneous cerebral oximetry and EEG monitoring is required to determine the causes of burst suppression. Targeted interventions to address cerebral desaturation may assist in mitigating burst suppression and consequently enhance postoperative cognitive function.
