A non-smoking 65-year-old woman received radioactive iodine (RAI) ablation (131I 50 mCi) after total thyroidectomy and a post-RAI whole-body scan revealed accumulation of radioiodine in the left thyroid bed. Computed tomography (CT) showed radioiodine-negative lung metastases. Subsequently, she underwent additional RAI treatment (131I 100 mCi). Approximately 9 years after the total thyroidectomy, diplopia, proptosis of the right eye, and oculomotor abnormalities appeared. T2-weighted fat-suppression images of orbital magnetic resonance imaging (MRI) showed a high signal intensity area and swelling in the inferior rectus muscle of the right eye, and laboratory tests showed high thyroid-stimulating hormone receptor antibody (TRAb) and thyroid-stimulating antibody (TSAb) levels, leading to the diagnosis of TAO. Triamcinolone acetonide (40 mg) was injected twice in the vicinity of the right inferior rectus muscle. Posttreatment orbital MRI showed improvement in inflammation and swelling of the inferior rectus muscle of the right eye; however, limited elevation of the right eye persisted. Having encountered this valuable case, it is crucial for clinicians to be aware that TAO can develop even after surgery for thyroid cancers.</p></div>","PeriodicalId":101253,"journal":{"name":"Thyroid Science","volume":"1 1","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2023-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950300023000071/pdfft?md5=dc8745fc67a1907a609c0ccc0fc3accc&pid=1-s2.0-S2950300023000071-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139107176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with Graves’ disease or adenomatous goiter sometimes show compressive symptoms by a diffuse large goiter. However, it is extremely rare to form tracheal varicose veins that cause hemoptysis. We herein report a case of massive hemoptysis from tracheal varices caused by a large Graves’ goiter.</p></div><div><h3>Case presentation</h3><p>An 82-year-old woman was diagnosed with Graves’ disease and had been treated with thiamazole for 15 years. She was taken to an emergency room because of massive hemoptysis. Bronchofiberscope revealed hemorrhage from remarkable varicose veins in the tracheal mucosa. Apixaban for concurrent paroxysmal atrial fibrillation was immediately withdrawn. After endotracheal epinephrine administration for recurrent bleeding, she was transferred to us. She presented with a large goiter that occupied her neck, suggesting that compression by the enlarged goiter may have caused tracheal varices. Preoperative echocardiography revealed tricuspid regurgitation and elevated pulmonary artery pressure that may have supported forming tracheal varices. Upon anesthesia induction, intubation was carefully conducted under bronchoscopy with endotracheal epinephrine administration, and total thyroidectomy was performed. The postoperative course was uneventful and she was discharged in 1 week. Bronchoscopy at 1 month after the operation showed complete disappearance of the tracheal varices.</p></div><div><h3>Conclusion</h3><p>Although tracheal varices due to compression by a large goiter are extremely rare, pulmonary hypertension may further accelerate establishing tracheal varices that leads to massive and recurrent hemoptysis. Tracheal varices associated with a large goiter can be treated by total thyroidectomy with careful intubation.</p></div>","PeriodicalId":101253,"journal":{"name":"Thyroid Science","volume":"1 1","pages":"Article 100006"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295030002300006X/pdfft?md5=41b7e487a38a8b5fcac9d8f6e051bebb&pid=1-s2.0-S295030002300006X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139015875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe form of congenital hypothyroidism causes growth retardation and intellectual disability. However, neuronal phenotypes caused by mild or moderate perinatal hypothyroidism have not yet been fully studied. To evaluate the effect of mild or moderate perinatal hypothyroidism on early development of postnatal mice, we induced hypothyroidism by administering propylthiouracil (PTU) during the perinatal period, from embryonic day 14 to postnatal day (PND) 21. We examined the motor coordination of newborns and vestibular function from PND 3 to PND 21. Animals in the moderate hypothyroid (50 ppm PTU-administered) group showed impaired motor coordination by a righting reflex test and a rotarod test, whereas animals in the mild hypothyroid (5 ppm PTU-administered) group showed normal motor coordination. Hypothyroidism did not affect vestibular function. Then, we measured mRNA and protein levels of glutamate receptor subunits in the cerebellum in developmental period. The levels of AMPA receptor subunit mRNA were altered initially, followed by alteration of NMDA receptor subunit mRNA in the later period. On the other hand, protein level has changed only in AMPA receptor subunit 1 (GluA1) on PND 8. These results indicate that moderate perinatal hypothyroidism impairs motor coordination during early postnatal development. The altered protein level of GluA1 in the cerebellum may be involved in such impairments.</p></div>","PeriodicalId":101253,"journal":{"name":"Thyroid Science","volume":"1 1","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950300023000058/pdfft?md5=f6c97fc1e52174740bb210609d131c06&pid=1-s2.0-S2950300023000058-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139024916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
