Comparison of aloe vera gel dressing with conventional dressing on pressure ulcer pain reduction: a clinical trial.

BACKGROUND: Aloe Vera has a strong analgesic and anti-inflammatory effect, and its use effectively controls pain. This study aimed to determine the effect of Aloe Vera gel versus saline on pain relief of pressure ulcers. METHODS: This study is a double-blind, randomized clinical trial conducted in Valiasr Hospital in Arak, Markazi Province, in the center of Iran from May 2020 to April 2022. Using the available sampling method, 95 patients with pressure ulcers were assessed for eligibility, 64 patients were selected, 33 patients were placed in the experimental and 34 patients in control. For the experimental group, the ulcers were first cleaned with normal saline to remove the slough and then the already prepared Aloe Vera gel was evenly applied. For control groups, the ulcers were first washed with normal saline to remove off the slough and then covered with a sterile cotton gage, and the wound was tightly bandaged with a cotton roll to keep the "daily dressing" in place. A visual pain scale was used to assess the patient's pain level. Data analysis was done using SPSS 17. Descriptive statistics, ANOVA, and greenhouse tests were used. The significance level was 0.05. RESULTS: The results showed that the average pain score in both groups had a downward trend; that is, both dressings effectively reduced pressure ulcer pain (P < 0.001). The greenhouse test results showed that the difference between the two groups was significant (P < 0.001). CONCLUSION: The results showed the effect of Aloe Vera gel in reducing pressure ulcer pain. Dressing with Aloe Vera gel is preferable to reducing pain during dressing changes in patients with pressure ulcers.

The effect of date palm on sexual function in infertile couples: a double-blind controlled clinical trial.

OBJECTIVE: Infertility has a significant impact on the sexual function of couples. The use of herbal medicine has been highly important throughout the history of medicine. The present study was conducted to evaluate the effect of date palm on sexual function of infertile couples. RESULTS: The present study was a double-blind, placebo-controlled clinical trial conducted on infertile women and their husbands who referred to infertility clinics in Iran in 2019. The intervention group was given a palm date capsule and the control group was given a placebo. Data were collected through female sexual function index and International Index of Erectile Function. The total score of sexual function of females in the intervention group increased significantly from 21.06 ± 2.58 to 27.31 ± 2.59 (P < 0.0001). Also, other areas of sexual function in females (arousal, orgasm, lubrication, pain during intercourse, satisfaction) in the intervention group showed a significant increase compared to females in the control group, which was statistically significant (P < 0.0001). All areas of male sexual function (erectile function, orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction) significantly increased in the intervention group compared to the control group (P < 0.0001). The present study revealed that 1-month consumption of date palm has a positive impact on the sexual function of infertile couples. Trial registration The trial was retrospectively registered in the Iranian registry of clinical trials at 2020-10-07 ( https://www.irct.ir/trial/51339 ; registration number: IRCT20200925048834N1).
