Abstract. [Purpose] This study focused on the effects of Manual Resistance Training (MRT) performed by elderly people for their lower extremities. [Subjects and Methods] The subjects were 53 elderly persons. The isometric strength of the right knee-extensor of the subjects in the intervention group was assessed after MRT once a week for 12 weeks followed by MRT, twice a week for 12 more weeks. Subjects in the control group only received the muscle strength measurement and did not perform MRT.[Results] From the baseline, the muscle strength of the intervention group significantly increased by 13.2% after 12 weeks, and 29% after 24 weeks. A significant difference was observed between the muscle strength of the intervention group and that of the control group. Those with greater muscle strength experienced relatively low muscle strength augmentation, compared with those with less muscle strength.[Conclusion]MRT resulted in improvements in muscle strength, similar to the results reported for a prior intervention with a resistance training method. The intensity of the MRT was inferred to be more than 70% of 1-repetition maximum. MRT may have less impact if it is performed by people with relatively high muscle strength.
We encountered a case of inflammatory myofibroblastic tumor (IMT) of the breast with simultaneous intracranial, lung, and pancreas involvement. Here, we present the clinical imaging results and report the significance of sonographic findings of breast IMT along with a review of the literature. A 16-year-old girl with a history of subarachnoidal hemorrhage was admitted to our hospital due to tonic-clonic seizure. Computed tomography (CT) and magnetic resonance imaging (MRI) showed multiple intracranial, lung, and pancreas mass lesions and a solitary mass lesion in the right breast. Breast ultrasonography showed a circumscribed oval-shaped hypoechoic mass with a central hyperechoic region. Power Doppler sonography revealed an unusual spiral-shaped flow signal. Breast tumorectomy was performed for definitive diagnosis, and pathological analysis indicated IMT. A literature review indicated that ultrasonographic findings of IMT of the breast are nonspecific, as in other systems or organs. It would be difficult to make a diagnosis of IMT of the breast preoperatively due to its rarity and the lack of specificity of clinical imaging findings. In addition, it is better to consider the possibility of IMT of the breast especially in younger patients without an obvious family history of hereditary breast cancer.
Objectives: We encountered a case of inflammatory myofibroblastic tumor (IMT) of the breast with multiple metastases to the brain, lung, and pancreas. Here, we present clinical imaging results and report the significance of sonographic findings of breast IMT along with a literature review. Methods: Case report and literature review. Results: A 16-year-old girl with a history of subarachnoidal hemorrhage was admitted to our hospital due to tonic-clonic seizure. Computed tomography (CT) and magnetic resonance (MR) imaging showed multiple mass lesions in the brain, lung, and pancreas and a solitary mass lesion in the left breast. Breast ultrasonography showed a circumscribed ovalshaped low-echoic mass with a central high-echoic region. Power Doppler sonography revealed an unusual spiral-shaped flow signal. Breast tumorectomy was performed for definitive diagnosis, and pathological analysis indicated IMT. Conclusions: A literature review indicated that ultrasonographic findings of IMTof the breast are nonspecific, as in other systems or organs. It would be difficult to make a diagnosis of primary IMT of the breast preoperatively due to its rarity and the lack of specificity of clinical imaging findings. In addition, the likelihood of IMTof the breast is unlikely in younger patients without an obvious family history of hereditary breast cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
