Effect of medical mask on voice in patients with dysphonia.

Objective: Medical masks have been shown to significantly influence speech communication in healthy people. The effect of mask-wearing on phonatory capability and daily communication exchanges in patients with voice disorders remains unclear. To evaluate the effect of the medical mask on acoustic parameters in patients with a voice disorder, we measured the voice frequency, quality, and intensity.

Cost-effective in-house-made whole blood materials for internal quality control in clinical flow cytometry analysis.

Internal quality control (IQC) is essential for ensuring the accuracy of results in clinical trials. However, there is a significant shortage of commercial quality control materials for IQC in flow cytometry. This study aimed to develop cost-effective in-house-made whole blood materials from clinically discarded samples to serve as IQC in clinical flow cytometry analysis.

Laparoscopic and Open Splenectomy and Hepatectomy.

Background And Objectives: Patients undergoing synchronous open splenectomy and hepatectomy (OSH) for concurrent hepatocellular carcinoma (HCC) and hypersplenism usually have major surgical trauma caused by the long abdominal incision. Surgical procedures that contribute to rapid recovery with the least possible impairment are desired by both surgeons and patients. The objective of this study was to explore outcomes in patients treated with simultaneous laparoscopic or open splenectomy and hepatectomy for hepatocellular carcinoma (HCC) with hypersplenism.
