ABSTRACT

BACKGROUND: Microwave treatment is a common physical therapy method that can increase the temperature and blood circulation of deep tissues, and is used for improving fracture repair. However, microwave treatment cannot be used if there is surgically implanted metal plate or screw. OBJECTIVE: To observe the dame of microwave treatment to the tissues surrounding the titanium alloy implants. METHODS: Forty-four New Zealand white rabbits were randomized into experimental and control groups. The model of the fracture at the middle of the femur was established in all rabbits, and the rabbits in the experimental group were implanted with titanium alloy internal fixation systems. A 30-day microwave treatment (2 450 MHz, 20 W or 40 W, 20 minutes daily) was applied to the fracture site in all rabbits at 3 days after operation. RESULTS AND CONCLUSION: After 20 W of wave microwave treatment, the temperature of tissues around the implants showed no significant increase or severe heat injury. While, 40 W of wave microwave treatment significantly increased the temperature of tissues around the implants and the tissue was damaged severely. Our results indicate that, the low-dosage microwave treatment may be a promising method in the rehabilitation therapy of fractures with titanium alloy internal fixation.

ABSTRACT

<p><b>BACKGROUND</b>Nowadays, social media tools such as short message service, Twitter, video, and web-based systems are more and more used in clinical follow-up, making clinical follow-up much more time- and cost-effective than ever before. However, as the most popular social media in China, little is known about the utility of smartphone WeChat application in follow-up. In this study, we aimed to investigate the feasibility and superiority of WeChat application in clinical follow-up.</p><p><b>METHODS</b>A total of 108 patients diagnosed with head and neck tumor were randomized to WeChat follow-up (WFU) group or telephone follow-up (TFU) group for 6-month follow-up. The follow-ups were delivered by WeChat or telephone at 2 weeks, 1, 2, 3, and 6 months to the patients after being discharged. The study measurements were time consumption for follow-up delivery, total economic cost, lost-to-follow-up rate, and overall satisfaction for the follow-up method.</p><p><b>RESULTS</b>Time consumption in WFU group for each patient (23.36 ± 6.16 min) was significantly shorter than that in TFU group (42.89 ± 7.15 min) (P < 0.001); total economic cost in WFU group (RMB 90 Yuan) was much lower than that in TFU group (RMB 196 Yuan). Lost-to-follow-up rate in the WFU group was 7.02% (4/57) compared with TFU group, 9.80% (5/51), while no significance was observed (95% confidence interval [CI]: 0.176-2.740; P = 0.732). The overall satisfaction rate in WFU group was 94.34% (50/53) compared with 80.43% (37/46) in TFU group (95% CI: 0.057-0.067; P = 0.034).</p><p><b>CONCLUSIONS</b>The smartphone WeChat application was found to be a viable option for follow-up in discharged patients with head and neck tumors. WFU was time-effective, cost-effective, and convenient in communication. This doctor-led follow-up model has the potential to establish a good physician-patient relationship by enhancing dynamic communications and providing individual health instructions.</p><p><b>TRIAL REGISTRATION</b>Chinese Clinical Trial Registry, ChiCTR-IOR-15007498; http://www.chictr.org.cn/ showproj.aspx?proj=12613.</p>
