Article Synopsis
  • The study aimed to identify the electrical characteristics of nonrecurrent inferior laryngeal nerves (NRILNs) during thyroid surgeries using intraoperative neuromonitoring (IONM) and look for associated vascular anomalies.
  • Out of 7865 thyroidectomy patients, 42 had NRILNs, with most cases detected through specific EMG signs and difficulties identifying the recurrent laryngeal nerve.
  • The findings showed a 0.53% prevalence of NRILNs, with a significant percentage having vascular anomalies, and suggest early detection methods during surgery to reduce the risk of nerve injury.

Article Synopsis
  • - The study assessed how the timing of HAPS after injecting Tc-MAA affects lung shunt fraction (LSF) and perfused volume (PV) in patients receiving selective internal radiation therapy (SIRT) for liver cancer.
  • - Researchers analyzed 51 HAPS sessions involving 40 patients, comparing LSF values and PV calculations from scans taken one hour and four hours post-injection.
  • - They found LSF values increased significantly from the first hour to the fourth hour, but PV calculations remained consistent; delaying HAPS could lead to overestimations of LSF, potentially impacting treatment decisions.

Background And Aim: Radioembolization (RE) is a one of the palliative treatments that have been used to down stage and/or increase the survival time in intermediate-advanced stages of HCC. We aimed to evaluate the clinical impact of RE and the clinical use of the albumin-bilirubin (ALBI) score as a predictor for survival in HCC patients.

Materials And Methods: Fifty-nine unresectable hepatocellular carcinoma (HCC) patients were enrolled.

Article Synopsis
  • - Chronic hepatitis B virus (HBV) infection can lead to hepatocellular carcinoma (HCC), and this study explores the methylation status of tumor suppressor genes RASSF1 and CDKN2AIP in patients with HBV-induced liver cirrhosis.
  • - The study involved 47 patients divided into two groups: those with both HCC and liver cirrhosis (22 patients), and those with only liver cirrhosis (25 patients).
  • - Results indicated that methylation levels of the CDKN2AIP gene were significantly lower in patients with HCC, suggesting that cfDNA methylation of these genes could be valuable for diagnosing HCC in HBV cirrhosis patients

Long-term albendazole treatment should be given to all patients with unresectable hepatic alveolar echinococcosis as dramatic regression is possible in 15%-20%. It may be prudent to prepare a living donor for possible salvage transplant in case of a severe complication. Preemptive transplantation in mildly symptomatic patients should be discouraged.

The Bethesda system (BS) for reporting thyroid fine-needle aspiration (FNA), which classifies nodules as nondiagnostic (ND), benign (B), atypia/follicular lesion of undetermined significance (AUS/FLUS), suspicious for follicular neoplasm (SFN/FN), suspicious for malignancy (SFM), or malignant (M), uses clinically valuable management guidelines. The authors employed a similar in-house classification system (IS) for thyroid FNAs, using the categories of ND, B, suspicious follicular cells (SFC), follicular lesion/neoplasm (FL/FN), SFM, and M. The authors compared IS and BS, and assessed the utility of BS in clinical practice.
