ABSTRACT
BACKGROUND: Treatment for frozen shoulder (FS) focuses on pain control and restoring movement and strength through physical therapy. We aimed to evaluate the efficacy of pulsed radiofrequency (PRF) lesioning of the suprascapular nerve for the treatment of FS pain. METHODS: Forty patients with FS were enrolled and randomly assigned into the intervention group (n = 20) that received PRF and a control group (n = 20) which received medical treatment (NSAIDs). Patients were followed-up for a total of three months. The primary outcome was the pain intensity, measured by the Numeric Pain Rating Scale (NRS). The secondary outcomes included shoulder range of motion (ROM) evaluation measured by simple shoulder test (SST); Likert-type-based patient satisfaction scale; and any adverse events (AEs) throughout the treatment period. All results were measured at baseline, at the end of one week, four weeks and 12 weeks after treatment. RESULTS: At 12 weeks post-procedure, the intervention group significantly improved their pain (NRS dropped to 2.80 ± 0.5) and there was significant improvement in range of motion (SST from 6.55% ± 2.0% to 76.50% ± 6.5) compared to control group. CONCLUSIONS: PRF lesioning of the SSN is a fast and effective modality in treating frozen shoulder pain and improving ROM for three months.

ABSTRACT
OBJECTIVE: To evaluate the effects of intraperitoneal instillation of lidocaine on postcesarean pain in patients with pariental periotoneal closure. METHODS: A sample of 370 pregnant women, presenting early in labor, with no history of abdominal surgery and with indications for cesarean section were operated on with closure of the parietal peritoneum. They randomly received either 200 mg of intraperitoneal lidocaine or sterile saline (0.9%). Pain scores on the first and fifteenth postoperative days were recorded and followed up every 2 weeks up to 8 months after surgery. RESULTS: Overall incidence and pain scores of epigastric and global abdominal pain were more frequent in the controls than in the lidocaine group. The incidence of persistent postcesarean pain after 8 months dropped from 20.8.0% to 10.8% (P<0.001) when intraperitoneal lidocaine was instilled. CONCLUSIONS: Intraperitoneal instillation of 200 mg of lidocaine decreased the incidence and scores of postcesarean pain when the parietal peritoneum was sutured. Further studies in a setting offering more effective acute pain control protocols, preferably with patient-controlled analgesia, are recommended to assess the use of lidocaine before it can be widely practiced.
