Abstract Background Mammography and Sonography are the important sensitive imaging modalities available in detection of breast cancer. Sonoelastography is a relatively new imaging technique which acts as a complementary tool to improve the diagnostic ability of ultrasound for evaluating patients with breast masses. Objective To evaluate the role of sonoelastography characterization information on solid breast lesions over conventional sonography and mammography either benign or malignant lesions to reduce the number of benign biopsies performed. Methods A prospective study was carried at private centers, starting from august 2019 till december 2019. Results The study conducted on 40 patients with palpable breast lesions classified to BIRADS 3 and 4a according to conventional ultrasound and mammographic criteria. Their ages ranged from 18 to '75 years with a mean age 47.72 14.91, 22 cases (55%) had no family history of pervious breast disease, and 18 cases (45%) had family history of pervious breast disease. All patients were subjected to full history taking, clinical examination, conventional gray scale ultrasound, and mammography and ultrasound elastography. All patients underwent histopathological assessment to reach the final diagnosis. Among Studied cases , 28 lesions were sampled by fine needle biopsy (70%) and 12 lesions were sampled by true cut needle (30%) .the results revealed 27 breast lesions were benign (67.5%), 9 malignant lesions (22.5%) and 4 lesions shows atypia (10%) according to histopathological assessment. Among final diagnosis of breast lesions fibro adenoma was the most frequent benign breast lesion detected as 12 lesions from 27 benign breast lesions were fibroadenoma., Also infiltrative ductal carcinoma was the moste frequent among malignant breast lesions as 5 lesions from 9 malignant lesions were infiltrative ductal carcinoma. Conclusion Ultrasoundelastography has significant complementray role beside conventional mammogram and ultrasound in characterization of solid breast lesions.

Purpose: To assess the role of Dynamic contrast enhanced magnetic resonance imaging in characterization of breast lesions and to differentiate benign from malignant lesions on the basis of their morphology and enhancement kinetics. Material and Methods: Sixty patients referred to the department of Radiodiagnosis for breast MRI over a period of twenty months were included. Dynamic contrast enhanced (DCE) Magnetic Resonance Imaging (MRI) was performed to differentiate breast lesions on the basis of morphology and enhancement kinetics. The lesions were classified accordingly into type I (progressive enhancement) Type II (plateau) and Type III (washout) kinetics. Morphology and curves of benign and malignant lesions were compared. Result: fifty one benign lesions were detected in 32 patients and 29 malignant lesions were seen in 22 patients, whereas six patients showed normal MRI. It was found that benign lesion were round or oval in shape with well circumscribed margin and showed homogenous contrast enhancement whereas malignant lesions were irregular with spiculated margin and showed heterogenous contrast enhancement. The distribution curve types of benign lesion were Type I (81.25%-26cases), Type II (18.25%-6cases). For malignant lesions Type I (4.54%-1case), Type II (22.72%-5cases) and Type III (72.72%-16cases). Conclusion: The shape of the time- signal intensity curve were an important criteria in differentiating benign from malignant lesions in dynamic breast MR imaging. A type III time curve is a strong indicator of malignancy and is independent of other criteria. DOI: http://dx.doi.org/10.3126/njr.v4i1.11366 Nepalese Journal of Radiology, Vol.4(1) 2014: 23-33

Summary Aim: Our goal was to determine the clinical usefulness of TI-201 to identify breast cancer in patients with suspicious breast lesions on clinical examination, and/or abnormal radiologic (mammography and/or ultrasonography) findings. Methods: TI-201 scintigraphy were performed in sixty-eight patients with 70 breast abnormalities (51 palpable, 19 nonpalpable) and compared with mammography and ultrasonography (US). Early (15 min) and late (3 h) images of the breasts were obtained following the injection of 111 MBq (3 mCi) of TI-201. Visual and semiquantitative interpretation was performed. Results: Final diagnosis confirmed 52 malignant breast lesions and 18 benign conditions. TI-201 visualized 47 of 52 (90%) overall malignant lesions. Thirty-eight of 40 (95%) palpable and 9 of 12 (75%) nonpalpable breast cancers were detected by TI-201 scintigraphy. The smallest mass lesion detected by TI-201 measured 1.5x1.0 cm. Eleven breast lesions were interpreted as indeterminate by mammography and/or sonography. TI-201 scintigraphy excluded malignancy in 7 of 8 (88%) patients with benign breast lesions interpreted as indeterminate. Five of the 18 (28%) benign breast lesions showed TI-201 uptake. None of the fibroadenoma and fibrocystic changes accumulated TI-201. TI-201 scintigraphy, mammography and ultrasonography showed 90%, 92%, 85% overall sensitivity and 72%, 56%, 61% overall specificity respectively. Twenty-one of the 28 (75%) axillary nodal metastatic sites were also detected by TI-201. In malignant and benign lesions, early and late lesion/contralateral normal side (L/N) ratios were 1.58 ± 0.38 (mean ± SD) and 1.48 ± 0.32 (p >0.05), 1.87 ± 0.65 and 1.34 ± 0.20 (p<0.05) respectively. The mean early and late L/N ratios of malignant and benign groups did not show statistical difference (p>0.05). Conclusion: Overall, TI-201 scintigraphy was the most specific of the three methods and yielded favourable results in palpable breast cancers, while it showed lower sensitivity in nonpalpable cancers and axillary metastases. Combined use of TI-201 scintigraphy with mammography and US seems to be useful in difficult cases, such as dense breasts and indeterminate breast lesions.

Abstract Can divide-and-rule colonial policy be responsible for contemporary ethnic tension? This paper empirically investigates the role of a divisive and extractive colonial policy on Hutu-Tutsi discord in Rwanda and Burundi. It shows that Hutu with a family history of subjugation to forced labour by Tutsi chiefs are less trusting of Tutsi today and less willing to partner with Tutsi for a cooperative task. This may have implications for agriculture insurance agreements since Hutu are more agrarian and Tutsi are more pastoral. Indeed, Hutu with a forced labour family history make fewer inter-household insurance agreements and are more likely to experience default.

Little research has explored the role of aggression, anger, and family history of incarceration as they relate to female offenders. The current study aimed to address this gap in the literature by investigating these possible risk factors for incarceration among both men and women. The survey involved 123 (61 female and 62 male) prisoners convicted for violent crimes and a comparison group of 118 (60 female and 58 male) adults from the community. We found that women (convicted and non-convicted) were more sensitive to provocation than men, while community adults showed higher levels of trait anger than prisoners. Detainees were more likely than community adults to have a relative in prison. Although male and female inmates were equally likely to have a relative in prison, they differed in their relation to the imprisoned relative. Male and female prisoners showed increased risk for incarceration of same sex, first degree relatives (father and brothers for men, and mothers for women). These results may contribute to improved understanding of incarcerated populations. As such, this represents a critical first step in creating recovery programs that are more gender appropriate.

Objective To investigate the role of quantitative analysis of T2 relaxation time in the magnetic resonance imaging (MRI) diagnosis of breast cancer. Methods The study enrolled patients with clinical breast masses who were examined using MRI at eight different echo times. The differences in T2 relaxation time of benign and malignant breast lesions were analysed. Results A total of 67 patients (67 breast lesions: 46 malignant, 21 benign) were examined. The mean ± SD T2 relaxation time was significantly lower in the 46 malignant lesions compared with the 21 benign lesions (82.69 ± 15.37 ms versus 95.48 ± 26.51 ms, respectively). The area under the curve was 0.731. Using 79.52 ms as the cut-off between benign and malignant breast lesions, a sensitivity of 85.7% and a specificity of 58.7% were obtained. Conclusions There was a significant difference in T2 relaxation time between benign and malignant breast lesions. The specificity of using T2 relaxation time alone for the differentiation of benign from malignant lesions was not high, but it could constitute a new adjunct in the MRI diagnosis of breast cancer.

For many adults, the risk of atherosclerosis can be reduced by intervention and treatment of known risk factors. Direct proof that similar intervention will be effective in children is not available. However, evidence suggests that prevention beginning in childhood will lead to a decrease in incidence of heart disease later in life. The majority of families are eager to take steps to prevent heart disease in their children, especially if there is a family history of early heart disease. It is the role of the pediatrician to identify those children at risk for early heart disease and to initiate advice on reducing risk factors.
