RESUMEN
BACKGROUND: Parathyroid carcinoma (PC) is a rare malignancy, often diagnosed incidentally through postoperative pathological examination. The occurrence of nodular goiter, intrathyroidal parathyroid carcinoma, contralateral parathyroid adenoma (PA), and papillary thyroid microcarcinoma (PTMC) is extremely uncommon, which prompted us to report our case experience. CASE PRESENTATION: We describe a 67-year-old male who presented with a cervical mass causing tracheal compression, which prompted him to seek medical advice. Based on preoperative auxiliary examination results from color Doppler ultrasound, SPECT parathyroid imaging, and blood tests, he was initially diagnosed with a suspected parathyroid adenoma and nodular goiter. Excision of the right lobe and isthmus of the thyroid, and left superior parathyroid gland was conducted, which were sent to intraoperative frozen pathological examination. During intraoperative observation, adhesion around the right thyroid lobe was discovered. Consequently, right central area lymph node dissection was performed due to suspicion of an aggressive malignant tumor. Histology and immunohistochemistry analysis revealed incidental intrathyroidal parathyroid carcinoma, contralateral parathyroid adenoma, classical papillary thyroid microcarcinoma, and nodular goiter. CONCLUSION: Parathyroid carcinoma should be highly suspected when extremely high levels of PTH and severe hypercalcemia are present, which cannot be simply explained by a preoperatively localized parathyroid adenoma, especially when suspicious malignant adhesion is found during intraoperative exploration. In cases where multifocal thyroid nodules are associated with increased uptake of 99Tc-sestamibi, the possibility of coexisting carcinomas should be considered, not only for thyroid malignancy but also for the potential presence of intrathyroidal parathyroid carcinoma.

BACKGROUND: The relationship between different surgical treatments and quality of life remains uncertain for differentiated thyroid carcinoma (DTC). The aim of this study is to compare the gasless endoscopic thyroidectomy trans-axillary approach (ET) and traditional open thyroidectomy (OT) through a prospective cohort study focusing on the rate of the efficacy, and quality of life (QoL). METHODS: This prospective observational longitudinal cohort study enrolled 134 female patients diagnosed with DTC from December 01/2021 to December 31/2022. Multiple scales were applicated to evaluate the differences in quality of life, effectiveness, safety, etc. between the two groups during preoperative and postoperative follow-up periods, including the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, version 3.0 (QOL-C30), Symptom Checklist (SCL-90), Scar Cosmesis Assessment and Rating (SCAR-Q), voice impairment score (VIS), swallowing impairment score (SIS), and neck impairment score (NIS). RESULTS: Among them, 68 accepted ET and 66 patients underwent OT. To enhance comparability between the two groups, the patients enrolled in this study are female. Compared with the OT group, the ET group performed significantly better postoperative physical quality of life, including sound (p = 0.036), swallowing (p < 0.001), and neck function (p = 0.010). The ET group was also associated with significantly better cosmetic satisfaction (p < 0.001), and relatively faster recovery in psychological and emotional situation. CONCLUSIONS: Gasless endoscopic thyroidectomy through an axillary approach leads to good cosmetic and psychological effects, improves postoperative QoL, and could be recommended for rapid postoperative recovery and involvement in daily and social activities.

Background: The occurrence of cervical lymph node metastasis in T1 stage papillary thyroid carcinoma (PTC) is frequently observed. Notably, lateral lymph node metastasis (LLNM) emerges as a critical risk factor adversely affecting prognostic outcomes in PTC. The primary aim of this investigation was to delineate the risk factors associated with LLNM in the initial stages of PTC. Methods: This retrospective analysis encompassed 3,332 patients diagnosed with T1 stage PTC without evident LLNM at the time of diagnosis. These individuals underwent primary surgical intervention at West China Hospital, Sichuan University between June 2017 and February 2023. The cohort was divided into two groups: patients manifesting LLNM and those without metastasis at the time of surgery. Additionally, T1 stage PTC patients were subdivided into T1a and T1b categories. Factors influencing LLNM were scrutinized through both univariate and multivariate analyses. Results: The incidence of LLNM was observed in 6.2% of the cohort (206 out of 3,332 patients). Univariate analysis revealed significant correlations between LLNM and male gender (P<0.001), tumor localization in the upper lobe (P<0.001), maximal volume of the primary tumor (P<0.001), largest tumor diameter (P<0.001), multifocality (P<0.001), and bilaterality (P<0.001), with the exception of age (P=0.788) and duration of active surveillance (AS) (P=0.978). Multivariate logistic regression analysis identified male gender (P<0.001), upper lobe tumor location (P<0.001), maximal primary tumor volume (P<0.001), and multifocality (P<0.001) as independent predictors of LLNM. However, age categories (≤55, >55 years), maximum tumor diameter, bilaterality, and surveillance duration did not exhibit a significant impact. Comparative analyses between T1a and T1b subgroups showed congruent univariate results but revealed differences in multivariate outcomes. In the T1a subgroup, gender, tumor location, and multifocality (all P<0.05) were associated with elevated LLNM risk. Conversely, in the T1b subgroup, tumor location, dimensions, and multifocality (all P<0.05) were significant predictors of LLNM risk, whereas gender (P=0.097) exerted a marginal influence. Conclusions: The investigation highlights several key risk factors for LLNM in T1 stage PTC patients, including gender, upper lobe tumor location, larger tumor size, and multifocality. Conversely, prolonged AS and younger age did not significantly elevate LLNM risk, suggesting the viability of AS as a strategic option in selected cases.
RESUMEN
OBJECTIVES: Assess the bioequivalence of lacosamide extended-release (XR) capsules and immediate-release (IR) tablets and answer real-world clinical questions regarding the use of lacosamide XR. METHODS: An open-label, randomized, two-treatment, two-sequence, oral comparative bioavailability study was conducted to assess the bioequivalence of two lacosamide formulations. Participants were randomized 1:1 to receive lacosamide XR capsules (400â¯mg once-daily) or IR tablets (200â¯mg twice-daily) in 1 of 2 sequences over 7-day periods. Primary outcome was the area under the lacosamide concentration-time curve over 24â¯h at steady-state (AUC0-τ,ss). Secondary outcomes were maximum (Cmax,ss) and minimum concentrations at steady-state (Cmin,ss). Bioequivalence was established when 90% confidence intervals (CIs) for geometric least square means ratios (GLSMs) were between 80% and 125%. Adverse events (AEs) and other safety outcomes were also assessed. Pharmacokinetic simulations, including adherent and partially adherent dosing scenarios with XR and IR formulations, modeled the clinical use of lacosamide XR. RESULTS: Thirty-five healthy adult males were enrolled in the bioequivalence study. After 7 days of study drug, mean AUC0-τ,ss, Cmax,ss, and Cmin,ss values were similar between XR and IR formulations; all 90% CIs for GLSMs were between 80% and 125%. AEs were mild and no serious AEs or other clinically significant safety findings were observed. Pharmacokinetic simulations suggested that partial adherence affected formulations similarly; and the best strategy for switching formulations was to take the morning lacosamide IR dose followed by the evening lacosamide XR dose, as this resulted in the most consistent lacosamide plasma concentrations. CONCLUSIONS: Once-daily lacosamide XR capsules were bioequivalent to twice-daily lacosamide IR tablets. Pharmacokinetic simulations indicated lacosamide XR and IR formulations were similarly affected by partial adherence, though once-daily dosing with lacosamide XR may offer clinical advantages, and formulations can be easily switched. These results support the use of lacosamide XR capsules as a once-daily alternative to lacosamide IR tablets.

BACKGROUND: Follicular thyroid carcinoma (FTC), the second most prevalent thyroid cancer after papillary thyroid cancer (PTC), tends to metastasize distantly, leading to poorer outcomes. Despite substantial research, a holistic bibliometric analysis of FTC literature is lacking. This study aims to fill this gap by employing bibliometric methods to track FTC research evolution. METHODS: English FTC publications were systematically gathered from the Web of Science. Bibliometric analysis, using R, VOSviewer, CiteSpace, and Excel, synthesized data and explored global research trends and topics. RESULTS: From 2000 to 2023, 9086 authors from 1953 institutions across 75 countries contributed to 1776 papers in 491 academic journals on FTC. The last two decades have witnessed a steady increase in publications related to FTC, with the United States leading in terms of publication volume. The United States dominated both in publications and citations, with the National Cancer Institute and Sheue-Yann Cheng as leading contributors. The journal 'Thyroid' featured the most publications, while the 'Journal of Clinical Endocrinology and Metabolism' ranked highest in citation frequency. Research focused on gene expression analysis and preoperative diagnostics, with recent trends shifting toward prognosis management and machine learning due to advances in medical technology and increased health awareness. CONCLUSION: This comprehensive bibliometric analysis has mapped the landscape of FTC research, highlighting key contributors, institutions, and thematic trends. Current discourse predominantly revolves around genetic analysis, prognostic determinants, and preoperative diagnostics in FTC. This foundational work guides future FTC research, providing insights into its evolution.
RESUMEN
To investigate the efficacy of chiropractic rehabilitation therapy in Crowe IV developmental dysplasia of the hip (DDH) patients after total hip arthroplasty. Seventy-two patients with Crowe IV type DDH hospitalized in the Department of Orthopedics I of Ya'an Hospital of Traditional Chinese Medicine from January 2021 to June 2023 were selected for the study, and they were divided into 36 cases in the chiropractic rehabilitation therapy group (the treatment group) and 36 cases in the traditional rehabilitation therapy group (the control group) according to the method of randomized grouping. All patients were evaluated at preoperative, 1, 3, and 6 months postoperatively for follow-up, and the muscle strength of the affected limb, the patient's walking gait, the shortened length of the affected limb, the visual analog scale score (VAS score), the Oswestry Dysfunction Index Score (ODI score), the Harris Hip Score, and the degree of pelvic tilt were recorded to evaluate the results of the study. A total of 4 subjects withdrew from the study, 2 in the treatment group, and 2 in the control group. The muscle strength of the affected limb, walking gait, shortened length of the affected limb, VAS score, ODI score, Harris score, and pelvic tilt in the treatment and control groups improved significantly compared with the preoperative period. Comparisons between the 2 groups revealed that at the final follow-up visit, the limp gait of the patients in the treatment group was significantly reduced, the shortened length of the affected limb was significantly reduced, the VAS score was significantly reduced, and the ODI score was significantly reduced, in the treatment group relative to that of the control group, Harris Hip Score was significantly improved, and the degree of pelvic tilt was significantly reduced, but the improvement in muscle strength of the affected limb was not statistically significant. In future clinical practice, we recommend that chiropractic rehabilitation be used as a routine adjunctive treatment after TKA in patients with Crowe IV DDH to optimize outcomes and improve patients' quality of life.

Background: Endoscopic thyroidectomy (ET) has witnessed significant advancements over the last three decades. Various surgical methods and approaches have been developed that minimize trauma, enhance aesthetics, and reduce psychological stress caused by scars. Papillary thyroid carcinoma is the main reason for thyroidectomy and ET represents an innovative technique for treating thyroid cancer. In this study, nearly three decades of scientific articles were analyzed and summarized to gain a better understanding by using bibliometric method. Methods: A total of 486 publications between 1996 and 2023 were retrieved from the Web of Science database through systematic searches. The objective of this study involved characterizing general information and investigating developmental trends and research frontiers. CiteSpace was employed to evaluate and visualize the results. Results: The query resulted 486 publications with a total citation frequency of 10,202. The top five countries in terms of the number of published articles were China, South Korea, the USA, Italy, and Japan. The top five countries in terms of literature centrality were Scotland, Israel, Brazil, the USA, and France. There were eight institutions with more than ten publications. The top ten institutions had a centrality score of 0.02 or above, indicating intensive research in this area and substantial collaboration among institutions. The most cited authors primarily originated from South Korea. Journals such as Surgical Endoscopy and Other Interventional Techniques, Surgical Laparoscopy Endoscopy & Percutaneous Techniques, Head and Neck Journal for the Sciences and Specialties of the Head and Neck, and Thyroid exerted considerable influence in this field. Keyword analysis results revealed that research predominantly focused on thyroid cancer and surgical approaches. Conclusions: This bibliometric study provides a comprehensive analysis of global productivity, collaboration, and research focus in the field of ET. The findings of this study serve as valuable guidance for future research in ET.
