Background: The prognostic significance of size of central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) remains unknown. Because postsurgical detectable stimulated thyroglobulin (DsTg) after radioiodine ablation may imply persistent or recurrent disease, we evaluated the association between size of CLNM and rate of DsTg in patients with PTC who underwent unilateral prophylactic central neck dissection.
Methods: To be eligible for analysis, the prophylactic central neck dissection specimen with <3 central lymph nodes (CLNs) or size of CLNM ≥1 cm as measured under the microscope was excluded. Of 132 specimens, 89 (67.4%) were eligible. Forty patients (44.9%) had no metastasis or pN0, 20 (22.5%) had micrometastasis (<2 mm) or pN1mic and 29 (32.6%) had macrometastasis (≥2 mm) or pN1mac. Postablation sTg level was measured 9 months after surgery. A multivariable analysis was conducted to identify independent factors for postablation DsTg.
Results: Larger-sized CLNM correlated significantly with younger age (p = 0.028), greater number of CLN retrieved (p = 0.016), greater number of metastatic CLN excised (p < 0.001), higher metastatic CLN ratio (p = 0.006) and postablation sTg level (p = 0.012). In the multivariable analysis, after adjusting for tumor size and metastatic CLN ratio, size of CLNM was an independent predictor of postablation DsTg (odds ratio 1.56, 95% confidence interval 1.09-2.24, p = 0.015). Relative to pN0, the odds ratios for postablation DsTg in pN1mic and pN1mac were 2.53 (95% confidence interval 0.35-19.00, p = 0.351) and 5.81 (95% confidence interval 1.22-27.70, p = 0.027), respectively.
Conclusions: Size of CLNM was an independent factor for DsTg 9 months after surgery. Patients with pN1mac were almost 6 times more likely to have postablation DsTg than those with pN0 or pN1mic.

Background: Smartphone overuse is associated with both psychological and physical health problems, including depression and musculoskeletal disorders. However, the association between smartphone overuse and neck pain remains unclear. We performed a meta-analysis to examine the relation between smartphone overuse and neck pain, and to identify high-risk usage patterns.

Objective: This study aimed to assess the degree of effect of central lymph node dissection on postoperative hypoparathyroidism incidence.
Methods: The incidence of postoperative hypoparathyroidism was compared between patients receiving thyroidectomy with central neck dissection for papillary thyroid carcinoma and those undergoing thyroidectomy for benign thyroid diseases (thyroid follicular adenoma and/or nodular goiter) necessitating surgical intervention.
Results: The incidence of postoperative hypoparathyroidism was not significantly different between the groups of lobe thyroidectomy for benign thyroid diseases and lobe thyroidectomy with ipsilateral central lymph node dissection for papillary thyroid carcinoma (immediate: 9.

Purpose: The value of stereotactic body radiotherapy (SBRT) in patients with oligometastatic head-and-neck squamous cell carcinoma (HNSCC) remains unclear, as existing evidence is primarily derived from retrospective single-center analyses with small patient cohorts. This study aimed to evaluate the outcomes of pulmonary SBRT in patients with oligometastatic HNSCC and to identify factors associated with survival.
Methods: This trinational multicenter cohort study, including 16 centers from XXX, XXX, and XXX, retrospectively analyzed patients with oligometastatic HNSCC undergoing SBRT for pulmonary metastases between 2010 and 2023.

An 8 yr old, male, mixed-breed dog was presented with a 2 mo history of progressive weakness, worsened in the last 2 days before examination. Neurological examination revealed ambulatory tetraparesis, ataxia, and proprioceptive deficits in all four limbs. Menace response was reduced in the right eye and discomfort was detected on neck manipulation.

Objective: Radiographic findings to identify central venous catheter misplacement in the arteries, which can cause lethal complications, have not been fully evaluated, and its training is difficult because it is rare. The purpose of this study is to clarify radiographic findings for differentiating central venous and misplaced arterial lines using virtual chest radiographs and elucidate their usefulness in training radiologists.
Methods: This retrospective study included 150 patients (mean age, 67 [SD, ±12] years; 97 men) who underwent colon cancer surgery between January 2018 and December 2020.
