Patients who recovered from conservative treatment of an appendiceal mass should undergo colonoscopy or barium enema to detect any underlying diseases and to rule out coexistent colorectal cancer. Routine interval appendectomy benefits less than 20% of patients.
Background and Purpose-The purpose of our study was to investigate the effects of different doses of neuromuscular electrical stimulation (NMES) on upper-extremity function in acute stroke patients with severe motor deficit. Methods-Sixty-six acute stroke patients were randomized to 3 groups: high NMES, low NMES, or control. The low-NMES group received 30 minutes of stimulation per day, and the high-NMES group received 60 minutes per day, for 4 weeks. The Fugl-Meyer Motor Assessment Scale, Action Research Arm Test, and Motor Activity Log were used to assess the patients at baseline, 4 weeks, and 12 weeks post baseline (follow-up).
Results-Both NMES groups showed significant improvement on Fugl-Meyer Motor Assessment and Action ResearchArm Test scales compared with the control group at week 4 and follow-up. The high-NMES group showed treatment effects similar to those of the low-NMES group.
Conclusions-Higher
Recent studies indicated nm23-H1 played a role in cancer progression. Therefore, we investigated clinical significance of nm23-H1 expression in oral squamous cell carcinoma (OSCC). In total, 86 OSCC specimens were immunohistochemically stained with nm23-H1-specific monoclonal antibodies. Immunohistochemical staining of nm23-H1 was confirmed by immunoblotting. The relations between nm23-H1 expression and clinicopathologic variables were evaluated by w 2 analysis. As increased size of primary tumour could escalate metastatic potential and the data of patients at the late T stage might confound statistical analyses, we thus paid special attention to 54 patients at the early T stage of OSCC. Statistical difference of survival was compared by a log-rank test. Immunohistochemically, nm23-H1 expression was detected in 48.8% (42 out of 86) of tumorous specimens. It positively correlated with larger primary tumour size (P ¼ 0.03) and inversely with cigarette-smoking habit (P ¼ 0.042). In patients at the early T stage, decreased nm23 expression was associated with increased incidence of lymph node metastasis (P ¼ 0.004) and indicated poor survival (P ¼ 0.014). Tumour nm23-H1 expression is a prognostic factor for predicting better survival in OSCC patients at the early T stage, which may reflect antimetastatic potential of nm23. Therefore, modulation of nm23-H1 expression in cancer cells can provide a novel possibility of improving therapeutic strategy at this stage. In addition, our results further indicated cigarette smoking could aggravate the extent of nm23-H1 expression and possibly disease progression of OSCC patients.
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.
