Utility of comet assay of DNA damage in the detection of malignant transformation of chronic liver cirrhosis.

Early detection of hepatocellular carcinoma (HCC) remains a great challenge in laboratory medicine. This study aimed to assess the ability to use the degree of DNA damage (using the comet assay) for the early detection of malignant transformation of liver cirrhosis (LC) to HCC. We used alkaline comet assay for measuring DNA damage in peripheral blood lymphocytes in 50 patients with chronic LC and 50 patients with HCC.

Feasibility and efficacy of erector spinae plane block versus transversus abdominis plane block in laparoscopic bariatric surgery: a randomized comparative trial.

Background: Overweight and obesity are growing public health concerns worldwide. Bariatric surgery is a modality of weight reduction; however, postoperative pain can increase the length of hospital stay, with all the associated consequences. While regional anesthesia is an available option, the feasibility of performing abdominal wall blocks on patients with obesity is questionable.
