  • Fine Needle Aspiration Biopsy Cytology (FNABC), which is known as the most accurate and cost-effective method for diagnosis of the thyroid nodule, may still result in indeterminate cases that are cellular paucity and show minor nuclear atypia. However, most cases are associated with suspicion of papillary thyroid carcinoma (PTC). A B-type Raf kinase (BRAF) mutation was found in about half of PTCs which is currently helping us to differentiate malignancies from benign lesions. Cases studied included 46 histological, confirmed PTC cases. FNABC 102 cell paucity and 74 atypia benign cases were previously diagnosed as suspicious of PTC using cytologic examination. These cases were analyzed for BRAF mutation by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) with a new restriction enzyme. In this study, the sensitivity and specificity were calculated and, BRAF mutation was detected by means of a histological method in 23 of 46 cases of PTC and no mutation was found in 22 cases. However, one case was not detected. In using FNABC, BRAF mutation was detected in 6 of 102 cases in cell paucity and in 11 of 74 cases in the atypia. Two cases were not detected in the atypia. The sensitivity and specificity of PCR-RFLP in FNABC were 60% and 97.4% respectively. Assessment of Formalin Fixed Paraffin Embedding (FFPE) block demonstrated similarly a 51.1% positive and 48.9% negative in PTC. Evaluation of BRAF mutation revealed high specificity and low sensitivity in using FNABC method. This study suggests that BRAF mutation analysis should be useful for the clinical diagnosis of PTC in FNABC with cytological findings suspicious for PTC.

  • Objective: To compare core needle biopsy (CNB) and repeat fine-needle aspiration (rFNA) to reduce the rate of diagnostic surgery and prevent unnecessary surgery in nodules initially diagnosed as atypia/follicular lesions of undetermined significance (AUS/FLUS). Materials and Methods: This study included 231 consecutive patients (150 female and 81 male; mean age ± standard deviation, 51.9 ± 11.7 years) with 235 thyroid nodules (≥ 1 cm) initially diagnosed as AUS/FLUS, who later underwent both rFNA and CNB. The nodules that required diagnostic surgery after the biopsy were defined using three different scenarios according to the rFNA and CNB results: criterion 1, surgery for low-risk indeterminate (categories I and III); criterion 2, surgery for high-risk indeterminate (categories IV and V); and criterion 3, surgery for all indeterminate nodules (categories I, III, IV, and V). We compared the expected rates of diagnostic surgery between CNB and rFNA in all 235 nodules using the three surgical criteria. In addition, the expected rates of unnecessary surgery (i.e., surgery for benign pathology) were compared in a subgroup of 182 nodules with available final diagnoses. Results: CNB showed significantly lower rates of nondiagnostic, AUS/FLUS, and suspicious for malignancy diagnoses (p ≤ 0.016) and higher rates of follicular neoplasm or suspicious for a follicular neoplasm (p < 0.001) and malignant diagnoses (p = 0.031). CNB showed a significantly lower expected rate of diagnostic surgery than rFNA for criterion 1 (29.8% vs. 48.1%, p < 0.001) and criterion 3 (46.4% vs. 55.3%, p = 0.029), and a significantly higher rate for criterion 2 (16.6% vs. 7.2%, p = 0.001). CNB showed a significantly lower expected rate of unnecessary surgery than rFNA for criterion 1 (18.7% vs. 29.7%, p = 0.024). Conclusion: CNB was superior to rFNA in reducing the rates of potential diagnostic surgery and unnecessary surgery for nodules initially diagnosed as AUS/FLUS in a scenario where nodules with low-risk indeterminate results (categories I and III) would undergo surgery.

  • 본 연구는 갑상샘 탄성초음파에서 탄성도 점수와 변형비를 이용한 방법이 양성과 악성결절의 감별진단에 유용한지를 평가하였다. 탄성초음파를 시행한 597명을 대상으로 하였으며, 세침흡인세포검사 결과를 바탕으로 후향적인 분석을 하였다. 갑상샘 결절의 양성과 악성에 따른 5단계의 탄성도 점수와 변형비의 차이분석은 카이제곱검정과 Mann-Whitney U test를 실시하였다. ROC 곡선분석을 통해 악성결절의 예측을 위한 탄성도 점수와 변형비의 최적의 cut off 값을 결정하였다. 양성과 악성결절 군의 분류에 따른 탄성도 점수의 동질성 비교와 변형비의 차이검증 결과에서 각각 통계적으로 유의한 차이를 보였으며(p=0.000), ROC 곡선분석에서 양성과 악성결절의 예측을 위한 탄성도 점수와 변형비의 AUC 0.842, 0.700, cut-off 값 3, 2.49로 결정되었다(p=0.001). 따라서 탄성도 점수와 변형비는 갑상샘 결절의 감별진단에 도움을 줄 수 있을 것이다.

  • In general, the anatomical location and number of parathyroid glands are well known, but they are often found in a variety of locations, making it difficult to find parathyroid glands during surgery. Besides Intra-thyroidal parathyroid adenoma is extremely rare case, and it is harder to identify in surgery. We encountered a 51-year-old patient with a thyroid nodule. The results of the additional blood test and the Tc-99m MIBI were combined to determine that the left lower lobe parathyroid adenoma was highly likely. This patient was treated with left thyroid lobectomy with parathyroid identification using Near-infrared (NIR) imaging. Afterwards, the biopsy confirmed that it was a parathyroid adenoma, and has since been monitored through outpatient observation without any problem. We present this rare case with a review of related literatures.

  • This study was to investigate the relationship between ultrasonographic examination and pattern identification classification on cinical studies in chinese medicine. We searched clinical studies related correlation between ultrasonographic examination and pattern identification classification in chinese medicine, that published from 2013 to 2016 in China National Knowledge Infrastructure (CNKI) databases by keywords, 'ultrasound(超?)', 'chinese medicine(中?)', 'syndrome differentiation (辨?)'. Seventeen studies were found. There were 7 studies of gynecological diseases including polycystic ovary syndrome and uterine myoma, 5 studies of fatty liver, 3 studies of arthritis, and 1 studie of thyroid nodule and lymphadenopathy respectively. As a result, ii is thought that there was a certain degree of correlation between the change of the ultrasonographic image and the pathological types according to traditional chinese medicine (TCM) syndrome differentiation and ultrasonographic examination could be used as secondary means for the TCM syndrome differentiation classification. In conclusion, by using ultrasonograph device in a medicinal way of TCM and traditional korean medicine (TKM), it is thought that more detailed and accurate diagnosis and treatment are possible and the evidence for reasonableness of syndrome differentiation in TCM and TKM its validity can be secured.

  • $^{201}Tl-^{99m}Tc$ 감영스캔이 시행되었던 65명의 환자에서 $^{201}Tl-^{99m}Tc$ 감영스캔의 진단적 가치와 위 음성과 위 양성의 원인에 대해 조사하였다. 이들 중 21예가 부갑상선선종으로 확진되었고, 이들에서 $^{201}Tl-^{99m}Tc$ 감영스캔의 예민도는 90.5%, 특이도는 97.6%였다. 위 음성을 보인 예는 낭종성 괴사를 보인 부갑상선선종과 크기가 $1.5{\times}1{\times}0.8 cm$ 정도로 작은 종양이었다. 위 양성을 보인 1예는 무 기능성 갑상선종이었다. 결론적으로 $^{201}Tl-^{99m}Tc$ 감영스캔은 부갑상선 종괴를 찾아내는데 특이도와 예민도가 높은 검사로 생각된다.

  • 목적 본 연구는 낭성 및 고형성 혼합 갑상선 결절 치료에서 고주파 절제술 단독요법과 에탄올 절제 후 고주파 절제술 요법의 유효성 및 안전성을 비교하고자 하였다. 대상과 방법 본 연구는 초음파 유도 하 조직검사에서 양성으로 확인된 243개의 낭성 및 고형성 혼합 갑상선 결절을 대상으로 진행됐으며, 243개의 결절은 243명의 환자로부터 진단되었다. 연구 대상이 된 결절들은 고주파 절제술 단독요법과 에탄올 절제 후 고주파 절제술 요법을 받은 군의 두 군으로 나누어 분류됐다. 본 연구는 각 군에서의 시술 후 부피 감소율, 치료 성공률, 증상 및 미용 문제의 개선 정도를 평가하였다. 또한 시술 후 연관된 합병증이나 부작용이 발생하였는지 확인하였다. 결과 고주파 절제술 단독 요법 군에는 204명의 환자가 포함되었고, 에탄올 절제 후 고주파 절제술 요법 군에는 39명의 환자가 포함되었다. 단독요법군과 혼합요법 군에서 최종 추적 검사 시 평균 부피 감소율은 각각 81.6%와 87.2%였다. 두 군에서의 장기적 치료 성공률은 각각 90.2%와 97.4%였다. 치료 결과는 마지막 추적 관찰 시기에서 두 군에서 유사하게 나타났다. 대부분 낭성 결절에 국한된 추가 분석에서도 두 군 간에 치료 효과에 있어 유의미한 차이가 없었다. 증상 및 미용적 문제는 두 군에서 모두 현저하게 개선되었다. 시술 후 연관된 큰 합병증은 두 군 모두에서 발생하지 않았다. 결론 에탄올 절제 후 고주파 절제술 혼합 요법이 고주파 절제술 단독요법에 비해 약간 더 나은 치료 방법이지만, 두 치료 요법 모두 낭성 및 고형성 혼합 결절의 치료에 안전하고 효과적인 방법이다.
