Progress in screening and follow-up studies of pulmonary ground glass nodules / 中华肿瘤杂志

With the wide application of high-resolution chest CT in health check-up, the ground glass nodule(GGN) has been increasingly detected. GGNs have a complex etiology and image features, which can develop fast or very slowly. Therefore, whether to follow up or to resect it is usually very difficult to be determined. Overdiagnosis or overtreatment frequently happens. According to the development of GGNs, the process can be clinically divided into four stages: biological onset stage (pre-detection stage), observational stage, clinical treatment stage and postoperative follow-up stage. This review summarizes the progress on the natural development process, imaging monitoring and differentiation, the optimal time of surgical treatment for GGNs based on the decision of multidisciplinary team. This revie wmay be helpful for clinicians to understand the rule of GGN development in the follow-up, and find an optimal time to give surgical intervention for improving the prognosis of and life quality of the GGN patients.

Developing a Computerized Reminder System and Evaluating the Effects on the Improvemtent of Cancer Screening / 간호학회지

PURPOSE: This study was aimed to develop a computerized reminder system and evaluate it's effect in terms of percent age change of screening, and satisfaction. METHOD: It was conducted through 6 phases : Analyzing the job and defining the basic input data, developing the information system, collecting and inputting data, testing the system, working with the system, and evaluating it's effect. Participants were 787 people (female 30-69 years, and males 40-49 years) in 2 dong of Suyoung gu, Busan, who haven't had cancer screening for the stomach, breast, or cervix since Dec. 2000. There were three experimental groups: a letter; calling and calling after the letter reminder, and a non-equivalent control group. To determine whether services were obtained, a telephone survey was done after two months of follow-up. RESULT: A cancer screening information system with five DB modules was develped. Overall compliance with screening was not statistically significantly changedbefore and after applying computerized reminders for all three screening sites. Only 16% were satisfied with the reminder. CONCLUSION: This data didn't show that a reminder effort was effective of screening. However, because the evaluation interval was too short to find a difference in screening rate, we recommend additional longer prospective follow up studies.

The application of ultrasonography in breast cancer′s screening of chinese women with dense breast / 中国普通外科杂志

Objective To explore the contribution of ultrasonic examination and localization in early breast cancer screening of chinese women with dense breast.Methods From February,2002 to April,2006,the breasts of 5 000 women were examined using ultrasonic examination,and in about 4 000 women a mass was detected,which included 142 cases of breast cancer proved by pathology with diameter ≤2cm occurred in patients with dense breast.In these parients,ultrasonic visualization and molybdenum target mammographic were performed.Results In these with breast cancer and dense breast,there were 47 cases(33.10%) with microcalcification detected by ultrasonography,the sensitivity rate was 74.60% and the accuracy rate was 88.73%.Only 38(26.76%) cases were detected by mammography,the sensitivity rate was(60.32)% and the accuracy was 82.39%.About 44.37% breast cancer with dense brast display as the(microcalcification).There were 110 cases(77.46%) of the small breast cancer detected by ultrasonography,the sensitivity was 88.71% and the accuracy rate was 90.14%.There were 100 cases(70.42%)(detected) by mammography,the sensitivity rate was 80.65% and the accuracy rate was 83.10%.Also,in 12 patients an unpalpation breast lesion was correctly excised by the use of ultrasonic localization.(Conclusions)(1)For the small breast cancer in dense breast the sensitivity and the accuracy of ultrasonography(surpassed) those of mammography.(2)The ultrasonic examination is an effective way for early breast cancer screening in young women with dense breast and flat breast.Ultrasonography can improve the rate of dignosis in early breast cancer,and also improve the breast-conserving surgical rate.Ultrasonography is worth of widespread use spreading.

Spinal Ultrasonography in Newborns and Infants with Cutaneous Manifestation of Spinal Dysraphism

The most important spinal disorders in childhood are malformations and mass lesions. High-resolution, real-time ultrasonography of the spine enables the differentation of intraand paraspinal structures in a significant way. This examination does not require sedation, does not use radiation, can be performed in the nursery or an incubator and is less expensive than computed tomography or magnetic resonance imaging. The sonographic appearence of the various kinds of spinal dysraphism is demonstrated and illustrated. Based on our preliminary experience spinal sonography appears to be useful in neonates and infants as the first imaging device for differentiation of cmplex malformation and as a screeing method for occult spinal dysraphism.
