Objective To investigate the ultrasonic features and pathological basis of follicular variant of papillary thyroid carcinoma (FVPTC). Methods Ultrasonic presentation of 30 patients with FVPTC conifrmed by surgery and pathology from the Seventh People′s Hospital of Shaoxing during March 2002 and December 2012 were analyzed retrospectively and compared with pathological results. Results Ultrasonic presentation of 30 FVPTC cases could be classiifed into three types:(1) Six cases (20%, 6/30) of typeⅠ, with typical sonographic features of papillary thyroid carcinoma:nodules with irregular shape, unclear boundary, and very low echo inside, microcalciifcation could be seen. (2) Fourteen cases (47%,14/30) of typeⅡ, presented as clearer iso-echoic or hypo-echoic nodules, with irregular shape, angled and lobular edge, rare microcalciifcation. (3) Ten cases (33%, 10/30) of typeⅢ, presented as adenoma-like features, nodule with clear boundary and regular edge, uniform medium echo inside. The microscopic structure characteristics could be divided into three categories:6 cases of typeⅠ, lesions were featured with no obvious capsule, irregular shape and inifltrative growth;14 cases of type Ⅱ, lesions with irregular shape, which invading the capsule with partial protrusion and peripheral small satellite lesions;10 cases of typeⅢ, lesions with more complete envelope, more regular shape with no signiifcant or lower level and smaller extent invasion of the capsule. Differences in morphology, boundary, aspect ratio, internal echo, presentation of microcalciifcations between the encapsulated type (typeⅡ,Ⅲ) and non-encapsulated type (typeⅠ) FVPTC were statistically signiifcant (Fisher′s exact test, all P<0.05). While the difference in lymph nodes involvement between them was not statistically signiifcant (Fisher′s exact test, both P>0.05). Conclusion Ultrasonic presentation of FVPTC show characteristics of both follicular tumor and papillary carcinoma, and the ultrasonic presentations are closely related to the pathological subtypes.

Objective To evaluate the reliability and validity of the Chinese version of Uncertainty Scale for Kids-22 (USK-22).Methods The Uncertainty Scale for Kids was translated and adapted according to Chinese culture.The reliability and validity of the Chinese version of USK were tested in 117children and adolescents with cancer.Results The rate of recovery was 100％.The rote of effective questionnaire was 95.7％.The patients were easily to understand and it cost them average 8 minutes to finish the questionnaires.Three factors were extracted by factor analysis and could explain 57.043％ of total variance.The correlations between each item and subscale ranged from 0.526 to 0.762.The Cronbach α of USK was 0.872 and the Cronbach α of each subscale ranged from 0.774 to 0.826.The testretest reliability was 0.835.Conclusions The Chinese version of USK is reliable and valid,and can be used to measure the level of uncertainty among Chinese children and adolescents with cancer.

Objective To investigate illness uncertainty state and explore its influencing factors in hospitalized children and adolescents with cancer.Methods A cross-sectional survey was performed in 112 children and adolescents with cancer aged 7～18 years old from two hospitals with the Chinese version of Uncertainty Scale for Kids-20 and the self-designed demographic questionnaire.Results The mean total scores of illness uncertainty was (45.16±6.67) points.The results of single-factor analysis showed that the factors influencing the uncertainty in illness of children and adolescents with cancer were as follows:age,personality characteristics,course of disease,the methods of treatment,current disease status,absence from school or not,the times of hospitalization,family monthly income,and the extent of parents' understanding about the disease-related knowledge.Multi-factor stepwise regression analysis showed that the main influencing factors of the uncertainty in illness were the current condition,family monthly income,absence from school or not and the extent of parents' understanding about the disease-related knowledge.Conclusions Illness uncertainty is common in children and adolescents with cancer.Nurses should attach importance to the impacts of illness uncertainty,and take effective interventions to decrease it,alleviate psychological pressure and improve quality of life in children and adolescents with cancer.
