Background: In the treatment of Onychocryptosis, chemical matricectomy with 88% phenol solution is one of the most common surgical procedures due to a recurrence rate of less than 5%, but it may produce a delay in healing time. The objective was to compare the healing time between phenol applications of 30 or 60 s. Methods: A comparative, prospective, parallel, randomized, and blinded clinical trial was registered with the European Clinical Trials Database. Twenty-seven patients (54 feet) with 108 affected nail folds were randomized and treated with chemical matricectomy with phenol. Each hallux was randomly assigned to one of two groups (60 vs. 30 s phenolization). Each patient and one investigator were blinded to the phenol application time in each foot. The outcome measurements were healing time, recurrence, pain, post-surgical bleeding, inflammation, and infection rate. Results: The 30 s application presents a shorter healing time (14.93 ± 2.81 days vs. 22.07 ± 3.16 days; p < 0.001) with a similar recurrence rate (p = 0.99). Post-operatory bleeding, pain, inflammation, and the infection rate did not show significant differences (p > 0.05). Conclusions: The 30 s phenol application time offers a shorter healing time than 60 s without affecting the effectiveness of the procedure, showing the same rate of complications.

Background: In onychocryptosis surgery, incisional and non-incisional matricectomy is indicated according to the stage. The chemical matricectomy with 88% phenol solution is the gold standard and a wedge resection is indicated for more advanced stages. The aesthetic reconstruction has the advantages of the incisional procedure without eponychium incisions and an effectiveness similar to the chemical matricectomy with phenol. Objective: To compare the recurrence and the healing time between the chemical matricectomy with phenol and the aesthetic reconstruction. Methods: A comparative, prospective, parallel, randomized, and one-blinded clinical trial was registered with the European Clinical Trials Database (EudraCT) with identification number 2019-001294-80. Thrity-four patients (56 feet) with 112 onychocryptosis were randomized in two groups. Thirty-six were treated with chemical matricectomy with phenol and 76 with aesthetic reconstruction. Each patient was blind to the surgical procedure assigned by the investigator. The primary outcome measurements were healing time and recurrence. The secondary outcome measurements were post-surgical bleeding, pain, inflammation, and infection rate. Results: The aesthetic reconstruction procedure presents a shorter healing time (8.2 ± 1.4 days vs. 21.3 ± 3.1 days; p < 0.001) with a similar recurrence rate (p = 0.98). Post-operatory bleeding, pain, inflammation, and the infection rate did not show significant differences (p > 0.05). Conclusions: The aesthetic reconstruction presents a shorter healing time, favoring the patients’ recuperation, with a recurrence similar to the chemical matricectomy with 88% phenol solution.

Background:More than half of the patients attending emergency centers need analgesics. Injectable analgesics are currently the most common pain control strategy, but entail complications. Fentanyl is one of the most commonly used pain-relief opiates available in various forms.Objective:The present study aims to compare analgesic effects of nebulized against intravenous fentanyl for controlling pain due to limb fracture.Method:The present double-blind clinical trial recruited 213 patients presenting with fractured limbs to emergency departments. The first group of patients received 1 micg/kg of intravenous fentanyl citrate from a solution of 50 micg/ml and 5 ml of normal saline in nebulized form (group A), and the second group intravenously received 5 ml of normal saline and 4 micg/kg of 50 micg/ml solution of fentanyl citrate in nebulized form, whose volume reached 5 ml with the addition of normal saline (group B). Then, pain level was frequently measured and compared in the two groups for 20 minutes.Results:The results obtained showed reduced pain level in both the groups. However, point-by-point comparison of pain in the two groups revealed significantly greater pain reduction in intravenous fentanyl group (P<0.001). The need for adjuvant pain relief medication was 8.3% in intravenous fentanyl group and 24% in nebulized fentanyl group, with a significant difference between the two groups (P=0.002).Conclusion:According to the results, although nebulized fentanyl is effective in controlling pain due to limb fracture, it was less effective than intravenous type, and unable to control pain in many cases.
