Objective: To evaluate the value of the 2020 diagnostic criteria (Cellucci criteria) for pediatric autoimmune encephalitis (AE) in children with suspected AE in a single center. Methods: The clinical data of 121 children hospitalized at the First Affiliated Hospital of Zhengzhou University from October 2019 to October 2021, with a diagnosis of suspected AE, were retrospectively collected and analyzed. The children were divided into definite antibody-positive AE (dAPAE), probable antibody-negative AE (prANAE), possible AE (pAE) and non-AE groups according to the Chinese expert consensus and the Graus criteria. A new diagnosis was made according to the Cellucci criteria which was compared with the clinical diagnosis to evaluate the diagnostic value of the Cellucci criteria. The Mann-Whitney U test, Kruskal-Wallis test, and χ² test were used to compare the differences among groups. The sensitivity and specificity were used to evaluate efficacy of the Cellucci criteria. Results: Among the 121 children, 72 were males and 49 were females, with an age of 10.3 (6.5, 14.0) years at disease onset. There were 99 cases diagnosed as AE according the clinical diagnosis (58 males and 41 females), of which 43 cases were diagnosed as dAPAE, 14 cases as prANAE and 42 cases as pAE, and the other 22 cases were not AE (14 males and 8 females). The top 2 initial symptoms in the 99 children with AE were seizures (53 cases, 53.5%) and abnormal mental behaviors (35 cases, 35.4%). And the most common symptoms during the course of the disease were abnormal mental behaviors (77 cases, 77.8%) and seizures (64 cases, 64.6%). There were statistically differences in the incidence of consciousness disorders, autonomic dysfunctions during the course of the disease and the length of hospitalization among the 4 groups (χ²=21.63, 13.74, H=22.60, all P<0.05). Ninety-six of the 121 children were tested for AE-related antibodies, of which 45 cases (46.9%) were antibody-positive. According to the Cellucci criteria, 42 cases were diagnosed as dAPAE, 34 cases as prANAE and 14 cases as pAE. Compared with the clinical diagnosis, the sensitivity of the Cellucci criteria for the diagnosis of the 3 types of AE were 93.02%, 92.86% and 87.88%, and the specificity were 96.23%, 74.39% and 86.36%, respectively. Conclusions: The Cellucci criteria has a high sensitivity and specificity for the diagnosis of pAE and dAPAE in the clinical management of children with suspected AE, while a high sensitivity but low specificity for the diagnosis of prANAE. Therefore, it is recommended to apply the Cellucci criteria selectively in clinical practice according to the actual situation, especially in the diagnosis of prANAE.

BACKGROUND: Warthin-like variant of papillary thyroid carcinoma (WLV-PTC) is a relatively rare variant of papillary thyroid carcinoma with favorable prognosis. However, preoperative diagnosis using fine-needle aspiration (FNA) specimens is challenging especially with lymphocytic thyroiditis characterized by Hürthle cells and lymphocytic background. To determine a helpful cytological differential point, we compared WLV-PTC FNA findings with conventional papillary thyroid carcinoma with lymphocytic thyroiditis (PTC-LT) and conventional papillary thyroid carcinoma without lymphocytic thyroiditis (PTC) regarding infiltrating inflammatory cells and their distribution. Preoperative diagnosis or potential for WLV-PTC will be helpful for surgeons to decide the scope of operation. METHODS: Of the 8,179 patients treated for papillary thyroid carcinoma between January 2007 and December 2012, 16 patients (0.2%) were pathologically confirmed as WLV-PTC and four cases were available for cytologic review. For comparison, we randomly selected six PTC-LT cases and five PTC cases during the same period. The number of intratumoral and background lymphocytes, histiocytes, neutrophils, and the presence of giant cells were evaluated and compared using conventional smear and ThinPrep preparations. RESULTS: WLV-PTC showed extensive lymphocytic smear with incorporation of thyroid follicular tumor cell clusters and frequent histiocytes. WLV-PTC was associated with higher intratumoral and background lymphocytes and histiocytes compared with PTC-LT or PTC. The difference was more distinct in liquid-based cytology. CONCLUSIONS: The lymphocytic smear pattern and the number of inflammatory cells of WLV-PTC are different from those of PTC-LT or PTC and will be helpful for the differential diagnosis of WLV-PTC in preoperative FNA.

BACKGROUND: The magnetic resonance imaging (MRI) findings of Hashimoto's encephalopathy (HE) are variable; images range from having a normal appearance, to showing ischemic lesions, demyelination, or vasogenic edema. CASE REPORT: A 57-year-old woman presented with a sudden onset of dysarthria and dizziness. Routine blood tests were normal and the MRI was unremarkable. After admission, she developed aphasic seizures and myoclonus, and eventually became comatose. A follow up MRI showed diffuse high signal intensities at the bilateral cerebral white matter on fluid attenuated inversion recovery imaging. The serum titers of the anti-thyroglobulin antibody and anti-thyroperoxidase antibody were increased. After 5 days of 1,000 mg/day of intravenous methylprednisolone infusion, she recovered rapidly. CONCLUSION: We propose that repeated brain MRIs are necessary for the diagnosis of HE. Diffuse leukoencephalopathy may be a pathologic finding on MRI and, in this case study, was shown to be reversible after applying an appropriate treatment.

A 31-year-old woman with a 15-year history of Takayasu's arteritis (TA) and a 13-year history of Hashimoto's thyroiditis presented with hematochezia. She received a diagnosis of Sjögren's syndrome at 1 month before her visit to Kyungpook National University Medical Center. Her colonoscopic findings were compatible with a diagnosis of ulcerative colitis (UC). She was treated with oral mesalazine, and her hematochezia symptoms subsequently disappeared. The coexistence of UC and TA has been reported; however, reports on the coexistence of UC and Sjögren's syndrome, or of UC and Hashimoto's thyroiditis are rare. Although the precise etiologies of these diseases are unknown, their presence together suggests that they may have a common pathophysiologic background. Furthermore, in patients with autoimmune or vascular diseases, including TA, systemic manifestations should be assessed with consideration of inflammatory bowel diseases including UC in the presence of gastrointestinal symptoms such as diarrhea and hematochezia.

There was no previous population-based study on the comparison of the risk of chronic spontaneous urticaria (CSU) between autoimmune thyroid diseases (AITD) and age- and gender-matched controls. The primary objective of this study was to evaluate the risk of CSU after diagnosis of AITD using national registry data from Korea. The secondary objective was to evaluate other risk factors of CSU. Based on the disease code diagnoses in 2003-2005, we composed an AITD group (n=3,659) and an age- and gender-matched control group (n=18,295). Each patient was tracked for whether CSU occurs or not until 2013. After adjusting for demographic differences and comorbidities, patients with AITD had a significantly higher rate of CSU compared to the control group (hazard ratio [HR], 1.46; 95% confidence interval [CI], 1.25-1.70; P<0.001). Among the AITD patients, the adjusted HR for CSU was higher in patients with Hashimoto's thyroiditis (HR, 1.50) than in those with Grave's disease (HR, 1.33), although the difference was not statistically significant (P=0.368). Analysis of CSU patients associated with AITD showed that female patients had a significantly higher risk of CSU compared to male ones (HR, 1.34; P=0.001) and that those with allergic rhinitis (HR, 1.51; P<0.001), atopic dermatitis (HR, 2.44; P<0.001), and asthma (HR, 1.50; P<0.001) had a significantly higher risk of CSU compared to patients without respective diseases. Our results demonstrated that AITD could be significantly associated with an increased risk of CSU.

PURPOSE: To evaluate the diagnostic accuracy of routine calcitonin measurement in patients with nodular thyroid disease. METHODS: Consecutive patients with nodular thyroid disease (n = 640) were studied. Serum calcitonin levels were measured under basal conditions, and when basal values were between 10–100 pg/mL, testing was repeated after pentagastrin (PG) stimulation. Patients with previously diagnosed or familial medullary thyroid cancer (MTC) were excluded. Patients were operated on when basal or stimulated calcitonin >100 pg/mL or when other surgical indications were present. RESULTS: Four cases of MTC were identified. MTC was diagnosed in 75% of patients with basal calcitonin >100 pg/mL. One out of 11 patients with basal calcitonin between 10–100 pg/mL was diagnosed with MTC. PG stimulation resulted in elevation in 4 cases, where 1 case was diagnosed with MTC. Positive predictive value for basal calcitonin levels in the preoperative diagnosis of MTC was 5% for values between 10–100 pg/mL and 100% for values >100 pg/mL. Possible reasons for false positivity were papillary thyroid cancer in 17%, renal insufficiency in 8.3%, Hashimoto thyroiditis in 17% and β-blocker use in 33%. Positive predictive value for the PG test (>100 pg/mL) was 25% in the entire series. The cost of adding calcitonin measurement (±PG stimulation) to the preoperative work-up, resulted in €912.68 per MTC patient to detect the disease. CONCLUSION: Basal calcitonin measurement together with PG stimulation in cases of basal calcitonin >10 pg/mL detects MTC in 0.62% of patients with nodular thyroid disease.

Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patient was treated with L-thyroxine at 0.15 mg daily. However, during admission, he developed symptoms of cardiac tamponade. Closed pericardiostomy was performed, after which the patient's chest discomfort improved, and his vital signs stabilized. Herein, we report a case of an adolescent with Noonan syndrome, who was diagnosed with Hashimoto thyroiditis with an unusual presentation of cardiac tamponade.
