Hashimoto's encephalopathy (HE) is a rare and underdiagnosed neuropsychiatric illness. We present the case of a 17-year-old girl who was admitted to a tertiary-care psychiatric center with acute onset psychosis and fever. Her psychotic symptoms were characterized by persecutory and referential delusions, as well as tactile and visual hallucinations. Her acute behavioral disturbance warranted admission and treatment in a psychiatric setting (risperidone tablets, 3 mg/day). She had experienced an episode of fever with a unilateral visual acuity defect approximately 3 years before admission, which was resolved with treatment. Focused clinical examination revealed an enlarged thyroid, and baseline blood investigations, including thyroid function test results were normal. Abnormal laboratory investigations revealed elevated anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-TG) levels (anti-TPO of 480 IU/mL; anti-TG of 287 IU/mL). Results of other investigations for infection, including cerebrospinal fluid examination, electroencephalography, and brain magnetic resonance imaging were normal. She was diagnosed with HE and was treated with intravenous corticosteroids (methylprednisolone up to 1 g/day; tapered and discontinued after a month). The patient achieved complete remission of psychotic symptoms and normalization of the anti-thyroid antibody titers. Currently, at the seventh month of follow-up, the patient is doing well. This case highlights the fact that in the absence of well-defined clinical diagnostic criteria, a high index of suspicion is required for early diagnosis of HE. Psychiatrists need to explore for organic etiologies when dealing with acute psychiatric symptoms in a younger age group.

BACKGROUND: This study examined the change in the trabecular bone score (TBS), areal bone mineral density (aBMD), and osteoporosis in postmenopausal women who underwent thyrotropin (TSH)-suppressive therapy for treating papillary thyroid cancer after a total thyroidectomy procedure. METHODS: We evaluated 36 postmenopausal women who received a total thyroidectomy for papillary thyroid cancer and were undergoing TSH suppressive therapy with levothyroxine. Postmenopausal women (n=94) matched for age and body mass index were recruited as healthy controls. The aBMD and TBS of the lumbar spine were compared between dual energy X-ray absorptiometry (DXA) at baseline and at follow-up after an average of 4.92 years. RESULTS: There was no significant difference in the rate of diagnoses of osteoporosis, osteopenia, or normal bone status between the 2 groups during the baseline DXA evaluation. However, the TBS was significantly lower whereas aBMD did not show significant difference at the time of baseline DXA measurement (1st DXA, 1.343±0.098 vs. 1.372±0.06317, P < 0.001; 2nd DXA, 1.342±0.095 vs. 1.370±0.062, P < 0.001). The TBS and aBMD did not differ significantly between the initial and follow-up DXA images in both groups of TSH suppressive patients and controls. CONCLUSIONS: The average value of TBS and aBMD did not significantly change during the follow-up period. The TSH suppressive therapy was revealed as not a significant factor for the progressive deterioration of bone status during long term follow-up.

Resistance to thyroid hormone (RTH) is a condition caused by a mutation in the thyroid hormone receptor gene. It is rarely reported in individuals with no family history of RTH or in premature infants, and its clinical presentation varies. In our case, a premature infant with no family history of thyroid diseases had a thyroid stimulating hormone level of 85.0 µIU/mL and free thyroxine level of 1.64 ng/dL on a thyroid function test. The patient also presented with clinical signs of hypothyroidism, including difficulties in feeding and weight gain. The patient was treated with levothyroxine; however, only free thyroxine and triiodothyronine levels increased without a decrease in thyroid-stimulating hormone levels. Taken together with thyroid gland hypertrophy observed on a previous ultrasound examination, RTH was suspected and the diagnosis was eventually made based on a genetic test. A de novo mutation in the thyroid hormone receptor β gene in the infant was found that has not been previously reported. Other symptoms included tachycardia and pulmonary hypertension, but gradual improvement in the symptoms was observed after liothyronine administration. This report describes a case involving a premature infant with RTH and a de novo mutation, with no family history of thyroid disease.

Digital medicine has the capacity to affect all aspects of medicine, including disease prediction, prevention, diagnosis, treatment, and post-treatment management. In the field of thyroidology, researchers are also investigating potential applications of digital technology for the thyroid disease. Recent studies using artificial intelligence (AI)/machine learning (ML) have reported reasonable performance for the classification of thyroid nodules based on ultrasonographic (US) images. AI/ML-based methods have also shown good diagnostic accuracy for distinguishing between benign and malignant thyroid lesions based on cytopathologic findings. Assistance from AI/ML methods could overcome the limitations of conventional thyroid US and fine-needle aspiration cytology. A web-based database has been developed for thyroid cancer care. In addition to its role as a nationwide registry of thyroid cancer, it is expected to serve as a clinical platform to facilitate better thyroid cancer care and as a research platform providing comprehensive disease-specific big data. Evidence has been found that biosignal monitoring with wearable devices may predict thyroid dysfunction. This real-world thyroid function monitoring could aid in the management and early detection of thyroid dysfunction. In the thyroidology field, research involving the range of digital medicine technologies and their clinical applications is expected to be even more active in the future.

Nuclear medicine has been offering diagnostic and therapeutic solution since the introduction of radioactive iodine for thyroid diseases since decades. However, the concept of theranostics has given a new found impetus to the use of pairs of radiopharmaceuticals for diagnosis and treatment. Presented here is a perspective on theranostics from Pakistan.

Concurrent presentation of acute hepatitis A virus (HAV) infection and Graves' disease has not been reported in literature worldwide. Although there is no well-established mechanism that explains the induction of Graves' disease by HAV to date, our case suggests that HAV infection may be responsible for inducing Graves' disease. A healthy 27-year-old female presented fever, palpitation, and diarrhea, and she was subsequently diagnosed as acute HAV infection. Concurrently, she showed hyperthyroidism, and the diagnosis was made as Graves' disease. She had never had symptoms that suggested hyperthyroidism, and previous thyroid function test was normal. Acute HAV infection was recovered by conservative management, however, thyroid dysfunction was maintained even after normalization of liver enzymes. Methimazole was used to treat Graves' disease. We report a case of concurrent acute HAV infection and Graves' disease in a patient without preexisting thyroid disease. This suggests that HAV infection may be a trigger for an autoimmune thyroid disease in susceptible individuals.

Atrial fibrillation (AF), the most common chronic arrhythmia in adults, is rarely reported in children. Moreover, most of the previously reported children with AF have comorbidities, such as structural heart diseases, rheumatic diseases, and thyroid diseases. This case report is about a healthy 9-year-old boy who was diagnosed with AF without cardiac anomaly. He visited the emergency department with chest pain and palpitation, lasting 2 hours. His electrocardiogram showed narrow-complex tachycardia, which led to the diagnosis of supraventricular tachycardia. The administration of adenosine revealed rapid irregular P waves. After electrical cardioversion, cardiac rhythm was converted to normal sinus rhythm. This case report suggests that when children with narrow-complex tachycardia visit the emergency department, the possibility of AF, in addition to supraventricular tachycardia, should be considered if the RR intervals are markedly irregular.

The Korean Society of Thyroid Radiology (KSThR) was founded as an affiliated subspecialty society of Korean Society of Radiology in 2010. The KSThR was originated from the thyroid radiology research committee which had started within the Korean Society of Neuroradiology in 2005. In the beginning, the research committee was organized to make a clinical guideline for ultrasonography (US) diagnosis and US-guided biopsy of thyroid nodules to cope with the rapidly increasing role of US imaging and the increasing burden of US-guided biopsy for thyroid nodules in the early 2000s. The KSThR proposed a subspecialty of thyroid radiology which is a medical subspecialty dealing with the imaging-based diagnosis and interventional treatment of thyroid disease. The KSThR has made an effort to make an advance in the research of thyroid imaging and intervention, which could provide scientific evidences for imaging-based management of nodular thyroid disease and thyroid cancers. The KSThR has published clinical guidelines of diagnostic imaging and interventional management of thyroid nodules, which included the US diagnosis and imaging-based management, fine-needle aspiration, core needle biopsy, and radiofrequency ablation therapy in thyroid nodules. The KSThR has a mission to play a leading role in the research and clinical practice of imaging-based management of thyroid disease, and the KSThR will make an advance in collaboration with Korean Thyroid Association.
