Breast hamartoma is a relatively rare pathology, composed of various amount of mammary glandular, fatty and fibrous tissue. Here, we report MR findings of two cases of hamartomas; one of them was incidentally found in her left breast during preoperative MRI in a woman with right breast cancer, and the other was presented as a large palpable mass. Both of them were confirmed by surgical excision. Breast hamartoma shows a well-defined mass with mixed signal intensity on T2-weighted image MRI and a little or focal enhancement on contrast-enhanced MRI.

PURPOSE: The purpose of this study was to verify the new hip protector design with respect to the comfort and mobility. The new hip protector was developed based on a pattern of draping and body shape of Korean elderly individuals. MATERIALS AND METHODS: An wearing characteristics evaluation was conducted on 101 elderly women wearing hip protector using a questionnaire of preference and ease of wearing. Hip protectors, with existing and newly developed belt and underwear types, which were previously preferred by the Korean elderly, were evaluated. RESULTS: The newly developed belt type (65.0%) and newly developed underwear type (30.1%) hip protectors were preferred to the existing type (3.9%) and existing underwear type (1.0%) ones. The convenience of the newly developed belt type was greater than 4 out of 5 points (1 for strongly disagree and 5 for strongly agree) for all nine measures, including fit, allowance, mobility, pad placement, pad thickness, pad size, material, design, ease of dressing, and ease of undressing. The newly developed hip protectors showed less discomfort than the existing ones. In particular, the newly developed belt type and developed underwear type improved sitting convenience by 31.1% and 26.1%, respectively, compared with the existing ones. CONCLUSION: The hip protectors developed in the present study is expected to provide better fit for the body shape of Korean elderly individuals and prevent hip fracture due to fall.

PURPOSE: Aging and atherosclerotic changes enhance the stiffness of the arterial wall, and the pulse wave travels faster in stiffer vessel. Measurement of the brachial ankle pulse wave velocity (baPWV) is a non-invasive method for evaluating the stiffness of the vessel wall. We investigated the relation between the baPWV and risk factors for atherosclerosis. METHOD: We studied 180 subjects (38 male and 142 female; mean age 46 years, range 24 to 76 years). The instrument used for evaluating the baPWV was a Vasoguard (VIASYS Healthcare, Dublin, Ohio, USA), and measurements were performed in the right arm and in both ankles. Data were analyzed using Pearson correlation, t-test, and multiple regression analysis. Multiple regression analysis was performed for age, sex, smoking, hypertension, height, weight, body mass index (BMI), total cholesterol, LDL, HDL, TG, and HbA1c. RESULT: Right and left baPWVs were significantly increased (P<0.05) in subjects with the following risks: older age, high body weight, high BMI, high total cholesterol, high LDL, high TG, high HbA1c, and low HDL. Right and left baPWVs were also significantly increased (P<0.05) in male subjects with a history of smoking and hypertension. Multiple regression analysis showed that age, sex, and LDL were independent determinants of the right and left baPWVs. CONCLUSION: This study provides evidence that increased age, male gender, and high serum LDL levels are risk factors that contribute to arterial stiffness. Measurement of the baPWV may be a useful method for evaluating vascular status.

Secondary degeneration after ischemic stroke has been demonstrated by computed tomography and magnetic resonance imaging. We report a 77-year-old man with striatal infarction followed by multifocal degeneration that developed in a stepwise manner at the ipsilateral substantia nigra and thalamus on diffusion-weighted images obtained at 4 weeks, 6 weeks and 20 weeks after onset. We also review the underlying pathophysiology and its clinical meanings.
