Fluoroscopy-guided Bipolar Radiofrequency Thermocoagulation Treatment for Discogenic Low Back Pain / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The efficacy of percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) for the treatment of discogenic low back pain (LBP) remains controversial. However, all the PIRFT studies utilized monopolar radiofrequency thermocoagulation (RFTC). The aim of this study was to investigate the safety and efficacy of bipolar RFTC for the treatment of discogenic LBP.</p><p><b>METHODS</b>A total of 23 patients with discogenic LBP were treated with single-level bipolar RFTC. The patients were assessed before the procedure and at 1 week, 1 month, 3 months, 6 months, and 1 year after the procedure. The primary outcome included the visual analog scale (VAS) score and the Oswestry Disability Index (ODI) score. The secondary outcome included pain relief, reduction of analgesic dose, and patient satisfaction.</p><p><b>RESULTS</b>The VAS and ODI scores were significantly decreased after bipolar RFTC treatment at all time points of follow-up (P < 0.05). Bipolar RFTC treatment also resulted in a significant change in all secondary measures, such as pain relief, reduction of analgesic dose, and patient satisfaction. No serious complications or neurological sequelae were observed in any of the patients.</p><p><b>CONCLUSIONS</b>Bipolar RFTC treatment can significantly attenuate pain and improve the function of patients with discogenic LBP.</p>

Clinical efficacy of different surgical treatment on cataract and vision / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the clinical efficacy and safety of phacoemulsification and small incision non -phacoemulsification cataract surgery, and provide better options for clinical cataract treatment. METHODS: According to the different operation methods, 98 cases of simple senile cataract patients in our hospital were divided into control group and treatment group, 49 cases in each. The control group received ultrasonic emulsification operation treatment; treatment group were treated by small incision non -phacoemulsification. Visual acuity, astigmatism values, average operation time, and complications were compared between two groups before and after operation. RESULTS: There was no significant difference in preoperative corneal astigmatism values of two groups at 3mo between two groups (P>0. 05). On other times, vision and corneal astigmatism were obviously better than those before operation (P0. 05). When the lens nucleus hardness was at Ⅰ~Ⅲ level, corneal endothelial cell count of two groups had no significant difference ( P>0.05). When the lens nucleus hardness was at Ⅳ ~ Ⅴlevel, there was statistical difference (P CONCLUSION: Small incision non-phacoemulsification cataract surgery has the similarly efficacy compared with phacoemulsification. It should be based on the actual situation of the hardness of nuclear to select the appropriate surgical treatment.
