Ectopic thyroid is thyroid tissue found in places other than the anterolateral aspect of the second to fourth tracheal ring. Mediastinal ectopic thyroid is rare and only few cases have been reported. The authors experienced a case of 41-year-old female patient with an anterior neck mass. The patient had mild chest discomfort when breathing with no other symptoms. Imaging studies suggested tumor of thymic tissue origin and surgical excision was done. The mass was successfully removed and histopathologically determined to be thyroid tissue. We hereby report with a review of literature a case of ectopic thyroid found in the mediastinum, which was successfully removed by transcervical incision.

Leiomyoma is a benign tumor that originates from smooth muscle and can develop anywhere in the body where smooth muscle is present. However, leiomyoma arising in the head and neck region are very rare. We experienced a case of a 74-year-old male patient with a right nasal floor mass. The patient complained of bleeding from the right nasal cavity, nasal congestion, and discharge. On physical examination, a relatively smooth-surfaced, well-demarcated mass was observed in the right nasal floor. Preoperative imaging was interpreted as a right nasolabial cyst, and endoscopic excision was performed. Histologic examination confirmed it to be vascular leiomyoma. The patient was followed up for 6 months postoperatively and remains stable with no recurrence of symptoms. We report a case of vascular leiomyoma arising from the nasal floor that was mistaken for a nasolabial cyst in a 74-year-old patient.

Background and Objectives:
Fibrin sealant (FS) is widely used to reduce postoperative bleeding. This analysis aimed to assess the efficacy of FS to reduce complications after rhinoplasty.Materials and Method We searched PubMed, Scopus, Embase, the Cochrane Library, and the Web of Science database for articles on FS and rhinoplasty from the inception of publication to December 29, 2021. Post-rhinoplasty complications, such as edema and ecchymosis, were recorded. The final meta-analysis was performed using three studies.
Results:
Two subgroups were created based on the FS usage after rhinoplasty. The FS effect on edema reduction was favorable on the postoperative day-1 (standardized mean difference [SMD]=-1.07 [-1.70; -0.45]). In addition, the FS effect on ecchymosis reduction was favorable on the postoperative day-1 postoperative (SMD=-1.33 [-2.15; -0.50]).
Conclusion
Our study shows that FS reduces the early complications of rhinoplasty.

Background/Aims:
Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal disorder that typically requires long-term maintenance therapy. However, little is known about patient preferences and satisfaction and real-world prescription patterns regarding maintenance therapy for GERD.
Methods:
This observational, cross-sectional, multicenter study involved patients from 18 referral hospitals in Korea. We surveyed patients who had been prescribed proton pump inhibitors (PPIs) for GERD for at least 90 days with a minimum follow-up duration of 1 year. The main outcome was overall patient satisfaction with different maintenance therapy modalities.
Results:
A total of 197 patients were enrolled. Overall patient satisfaction, patient preferences, and GERD health-related quality of life scores did not significantly differ among the maintenance therapy modality groups. However, the on-demand therapy group experienced a significantly longer disease duration than the continuous therapy group. The continuous therapy group demonstrated a lower level of awareness of potential adverse effects associated with PPIs than the on-demand therapy group but received higher doses of PPIs than the on-demand therapy group. The prescribed doses of PPIs also varied based on the phenotype of GERD, with higher doses prescribed for non-erosive reflux disease than erosive reflux disease.
Conclusion
Although overall patient satisfaction did not significantly differ among the different PPI maintenance therapy modality groups, awareness of potential adverse effects was significantly different between the on-demand and continuous therapy groups.

Schwannoma is benign tumor that can occur in any part of the nerve that contains a Schwann cell. It is rare in the head and neck region and is characterized by common postoperative neurologic symptoms. We experienced a cervical schwannoma in a 22-year-old young man. Except for a foreign body sensation in the neck and a mass in the anterior region, there were no other complaints. A retropharyngeal schwannoma was most suspected considering neck computed tomography, magnetic resonance imaging, laryngoscopy and fine needle aspiration. Surgical treatment was performed, and the origin of the schwannoma was diagnosed as the tonsillar branch of the glossopharyngeal nerve. Histopathological examination confirmed the presence of a schwannoma with typical characteristics. After surgery, the patient recovered without any side effects. We report this case with a review of the literature.

Objective:
This study examined the diagnostic validity of a three-item ultra-brief screening tool for online gaming disorder in line with the gaming disorder criteria in the International Classification of Diseases 11th Revision.
Methods:
The Three-item Gaming disorder Test-Online-Centered (TIGTOC) was composed of three items using a four-point Likert scale selected from the Internet Game Use-Elicited Symptom Screen (IGUESS). Among a cohort of 2319 young-adolescent Internet users, the baseline data of 228 healthy controls and 45 Internet-gaming-disorder cases were analyzed. Receiver operation characteristic (ROC) analysis was performed using mental health specialists’ diagnoses as the gold standard.
Results:
The ROC curve analysis showed an area under the curve of 86%. Using a cut-off score of 4 from a full range of 0–9, the sensitivity, specificity, and Cronbach’s α were 72%, 90%, and 0.811, respectively. TIGTOC scores was positively associated with time spent on online gaming, depressive symptoms, attention-deficit/hyperactivity disorder symptoms, and addictive Internet use.
Conclusion
The TIGTOC appears to be a brief, valid, and reliable screening tool for online gaming disorder within the community or in primary care settings.
