Background: Treating patients with head and neck adenoid cystic carcinoma (HNACC) presents surgical problems in various scenarios. Limited studies explore definitive radiation's impact on patient survival, with inadequate data correlating it to postoperative radiotherapy. Using the Surveillance, Epidemiology, and End Results (SEER) program, we conducted an objective analysis to evaluate the impact of definitive radiation on the survival of HNACC patients without distant metastases, aiming to uncover its nuanced pros and cons., Methods: This study conducted a comprehensive analysis of individuals diagnosed with HNACC within the SEER database from 2000 to 2023. Disease-specific survival (DSS) and overall survival (OS) were evaluated using diverse statistical methods. Propensity score matching (PSM) reduced covariate variations and selection biases, allowing for comparisons of postoperative and definitive radiotherapy groups., Results: A total of 2,072 patients were encompassed within this study. The postoperative radiotherapy group yielded significant advantages in OS and DSS (P<0.001). In matched cohorts, the 5-year prognostic OS stood at 55% and 37%, respectively, while DSS figures were 65% and 46%, correspondingly. In advanced T4 cases, DSS differences lacked significance (P=0.42). Additionally, the outcomes of OS and DSS were notably influenced by variables such as T-stage, N-stage, tumor stage, and chemotherapy., Conclusions: Surgical intervention remains a pivotal component of comprehensive treatment for patients diagnosed with operable HNACC. Definitive radiation is appropriate for less treatable situations, particularly in local advanced HNACC. Systemic treatment may assist HNACC patients at risk of distant metastases., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tcr.amegroups.com/article/view/10.21037/tcr-24-1221/coif).

As a variant of recurrent inferior laryngeal nerve (RILN), the nonrecurrent inferior laryngeal nerve (NRILN) is closely related to the occurrence of abnormal subclavian artery (ASA). The nonrecurrent inferior laryngeal nerve has been found in patients without arterial abnormalities, which is seen in the coexistence of NRILN and RILN, but it is easily confused with sympathetic-inferior laryngeal anastomosis branch (SILAB). We encountered 2 right NRILN patients without ASA during thyroid surgery. This article summarizes the characteristics of these cases and proposes methods to distinguish the coexistence of NRILN and RILN from SILAB. So far, 11 articles have reported 16 cases of NRILN without arterial abnormalities. In patients without artery abnormality, the vagus nerve could send out a descending branch NRILN at the bifurcation of the carotid artery and enter the larynx after anastomosis with RILN. Adequate dissection of the carotid sheath may avoid confusion with SILAB, and neural monitoring is also expected to provide a reference for the identification., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Helicobacter pylori (H. pylori) infection and iron deficiency anemia are prevalent in disadvantaged populations worldwide. The benefit of H. pylori eradiation for iron deficiency anemia has been extensively studied, but data are still equivocal., Methods: A search in The Cochrane Library, PUBMED, EMBASE, EBM Review databases, Science Citation Index Expanded, and CMB (Chinese Biomedical Literature Database) was performed. Randomized controlled trials (RCTs) comparing anti-H. pylori plus oral iron to oral iron alone for the iron deficiency patients in whom H. pylori was positive were selected for meta-analysis. Reviev Manager 5.0 software was used for the performance of meta-analysis., Results: Sixteen randomized controlled trials totaling 956 patients were included. The meta-analysis showed that the difference from baseline to endpoint of hemoglobin (Hb), serum iron (SI), and serum ferritin (SF) was statistically significantly different between anti-H. pylori treatment plus oral iron and oral iron alone (SMD, Hb 1.48; 95% CI, 0.96, 2.00; p < 0.00001; SI 1.15; 95% CI, 0.87, 1.43; p < 0.00001; SF 1.84; 95% CI, 1.20, 2.48; p < 0.00001, respectively)., Conclusions: Our study suggests that treatment of H. pylori infection could be effective in improving anemia and iron statue in IDA patients infected by H. pylori, particularly in patients with moderate or severe anemia.
