Solitary Asymptomatic Thyroid Metastasis from Hepatocellular Carcinoma Detected by FDG-PET/CT
Thyroid metastases from hepatocellular carcinoma (HCC) seldom occur and are often difficult to diagnose because of their asymptomatic clinical course. We evaluated a very rare case of solitary thyroid metastasis from HCC that showed high uptake of fluorine-18 fluorodeoxyglucose (FDG), when imaged using fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). The patient was a 74-year-old man and presented with a remarkably elevated des-gamma-carboxy prothrombin level of 1,157 mAU/ml 22 months after hepatic lobectomy. FDG-PET/CT imaging revealed a hypodense tumor with high FDG uptake, with a maximum standardized uptake value of 5.2 in the thyroid left lobe. Solitary thyroid metastasis from HCC was suspected and subsequent fine needle aspiration did indeed reveal HCC. The patient received left thyroidectomy with left regional lymph node dissection. Two months after left thyroidectomy, contrast-enhanced computed tomography showed local recurrence, and the patient received ongoing radiotherapy treatment. To our knowledge, the present study is the first to demonstrate the feasibility of FDG-PET/CT in the diagnosis and management of clinically diagnosed, asymptomatic, solitary thyroid metastasis from HCC
ヒセイキボ シュウダン カラノ √B1 ノ ブンプ ノ コウジ キュムラント
Let √ be the standardized third moment statistic in random samples of n observations from a nonnormal population. We only assume that the population has finite cumulants of requisite order. In this papar, the higher order cumulants of √ required for deriving the Edgeworth expansion up to order 1/n are given
Quality of care associated with number of cases seen and self-reports of clinical competence for Japanese physicians-in-training in internal medicine
BACKGROUND: The extent of clinical exposure needed to ensure quality care has not been well determined during internal medicine training. We aimed to determine the association between clinical exposure (number of cases seen), self- reports of clinical competence, and type of institution (predictor variables) and quality of care (outcome variable) as measured by clinical vignettes. METHODS: Cross-sectional study using univariate and multivariate linear analyses in 11 teaching hospitals in Japan. Participants were physicians-in-training in internal medicine departments. Main outcome measure was standardized t-scores (quality of care) derived from responses to five clinical vignettes. RESULTS: Of the 375 eligible participants, 263 (70.1%) completed the vignettes. Most were in their first (57.8%) and second year (28.5%) of training; on average, the participants were 1.8 years (range = 1–8) after graduation. Two thirds of the participants (68.8%) worked in university-affiliated teaching hospitals. The median number of cases seen was 210 (range = 10–11400). Greater exposure to cases (p = 0.0005), higher self-reports of clinical competence (p = 0.0095), and type of institution (p < 0.0001) were significantly associated with higher quality of care, using a multivariate linear model and adjusting for the remaining factors. Quality of care rapidly increased for the first 100 to 200 cases seen and tapered thereafter. CONCLUSION: The amount of clinical exposure and levels of self-reports of clinical competence, not years after graduation, were positively associated with quality of care, adjusting for the remaining factors. The learning curve tapered after about 200 cases
Research and development of exclusive equipment for cell-free and concentrated ascites reinfusion therapy (CART) by medical-industrial, hospital-university, and multifarious worker cooperation
Cell-free and concentrated ascites reinfusion therapy(CART)is an effective and safe therapy for patients with refractory ascites or pleural effusion. CART was initially indicated for cirrhotic ascites, and has come to be widely used for malignant ascites. Recently, cancer therapy that applies cancer cells obtained by filtration process is considered, and CART attracts attention as one of the important therapies to support future cancer therapy. However, the numbers of CART in Japan is not sufficient because the equipment for CART is high price and large. Additionally, the specialized medical staff such as clinical engineers is necessary for CART because of complicated operation. Therefore, we think that development of next-generation type equipment for CART that can be performed safely, easily, and reliably is necessary. We could develop the exclusive equipment for CART according to the project management by multifarious worker cooperation in five years
