The aim of this experimental study was to assess whether 5 weeks of preoperative supplementation with vitamin D affects the intensity of pain and the level of inflammatory markers in patients undergoing posterior lumbar interbody fusion (PLIF) followed by rehabilitation. 42 patients were divided, by double-blind randomization, into two groups: supplemented (SUPL) vitamin D (3200 IU dose of vitamin D/day for 5 weeks) and placebo group (PL) treated with vegetable oil. The 10-week program of early rehabilitation (3 times a week) was initiated 4 weeks following PLIF. Measurements of serum 25(OH)D 3 and CRP, IL-6, TNF-α, and IL-10 were performed. Pain intensity was measured using VAS. After supplementation with vitamin D serum, the concentration of 25(OH)D 3 significantly increased in the SUPL group ( ∗ p < 0.005) and was significantly higher as compared to the PL group ( ∗ p < 0.001). A significant reduction in pain intensity was observed 4 weeks after surgery and after rehabilitation in both groups. In the SUPL group, serum CRP and IL-6 concentration significantly decreased after rehabilitation, compared with the postsurgical level ( a p < 0.04). The level of TNF-α was significantly lower after rehabilitation only in the supplemented group ( ∗ p < 0.02). There were no significant changes in the IL-10 level in both groups during the study. Our data indicate that supplementation with vitamin D may reduce systemic inflammation and when combined with surgery and early postsurgical rehabilitation, it may decrease the intensity of pain in LBP patients undergoing PLIF. Data indicate that LBP patients undergoing spine surgery should use vitamin D perioperatively as a supplement.

Intravenous lidocaine, a potent local anesthetic with analgesic and anti-inflammatory properties, has been shown to be an effective adjunct that reduces intra- and postoperative opioid consumption and facilitates pain management in adults. While it shows promise for use in the pediatric population, limited evidence is available. Objectives To determine if general anesthesia with intraoperative intravenous lidocaine infusion versus general anesthesia without intravenous lidocaine infusion in children undergoing laparoscopic appendectomy decreased opioid requirements intra- and postoperatively. Design A single-center parallel single-masked randomized controlled study. A computer-generated blocked randomization list was used to allocate participants. The study was conducted between March 2019 and January 2020. Setting: Pediatric teaching hospital in Poland. Participants Seventy-four patients aged between 18 months and 18 years undergoing laparoscopic appendectomy. Seventy-one patients fulfilled the study requirements. Intervention Intravenous lidocaine bolus of 1.5 mg/kg over 5 min before induction of anesthesia followed by lidocaine infusion at 1.5 mg/kg/h intraoperatively. The infusion was discontinued before the patients’ transfer to the postanesthesia care unit (PACU). Primary outcome measure The primary outcome measure was total nalbuphine requirement in milligrams during the first 24 h after surgery. Secondary outcome measures The secondary outcome measures were intraoperative fentanyl consumption, intraoperative sevoflurane consumption, time to the first rescue analgesic request, incidence of postoperative nausea and vomiting during the first 24 h after surgery, frequency of side effects of lidocaine. Results Children (n = 74) aged 5–17 randomly allocated to receive intraoperative lidocaine infusion (n = 37) or no intervention (n = 37). Seventy-one were included in the analysis (35 in the study group and 36 in the control group). There was no difference in the cumulative dose of nalbuphine in the first 24 h after removal of the endotracheal tube between groups [median of 0.1061 (IQR: 0.0962–0.2222) mg/kg in the lidocaine group, compared to the control group median of 0.1325 (IQR: 0.0899–0.22020) mg/kg, p = 0.63]. Intraoperative fentanyl consumption was lower in the lidocaine group [median of 5.091 (IQR: 4.848–5.714) μg/kg] than in the control group [median of 5.969 (IQR: 5.000–6.748), p = 0.03]. Taking into account the additional doses administered based on clinical indications, the reduction in the requirement for fentanyl in the lidocaine group was even greater [median of 0.0 (IQR: 0.0–0.952) vs 0.99 (IQR: 0.0–1.809) μg/kg, p = 0.01]. No difference was observed in the sevoflurane consumption between the two groups [median of 32.5 ml (IQR 25.0–43.0) in the lidocaine group vs median of 35.0 ml (IQR: 23.5–46.0) in the control group, p = 0.56]. The time to first analgesic request in the lidocaine group was prolonged [median of 55 (IQR: 40–110) min in the lidocaine group vs median of 40.5 (IQR: 28–65) min in the control group, p = 0.05]. There was no difference in the frequency of PONV between the two groups (48.57% in the lidocaine group vs 61.11% in the control group, p = 0.29). No lidocaine related incidence of anaphylaxis, systemic toxicity, circulatory disturbances or neurological impairment was reported, during anesthesia or postoperative period. Conclusions Intraoperative systemic lidocaine administration reduced the intraoperative requirement for opioids in children undergoing laparoscopic appendectomy. This effect was time limited, and hence did not affect opioid consumption in the first 24 h following discontinuation of lidocaine infusion. Trial registration NCT03886896.

BackgroundPelvic floor muscle exercises are a widely used and well-established form of stress incontinence treatment, with success rates varying from 21% to 84%, although with a better subjective than objective outcome.Material/Methods“Incontinence Impact Questionnaire” (IIQ), PFM EMG assessment was done at the beginning and after the 6-week training program.ResultsStatistically significant differences appeared in the BASE and R values. In the symptomatic group (with SUI symptoms), the value of BASE was 3.26 μV, and after training it was 3.95 μV. The R values before and after training were 4.55 μV and 4.25 μV. In the symptomatic group (without SUI symptoms), the value of BASE was 2.88 μV and 3.52 μV and R values were 7.16 μV and 3.92 μV. In the control group, BASE was 3.05 μV and 4.11 μV and R was 7.82 μV and 4.39 μV.ConclusionsThe results indicate that a 6-week training process influences PFM EMG activity in pregnant women. During Q, the value of PFM activity after a training session tended to increase in the symptomatic and control groups, but in the symptomatic group it remains practically unchanged. Our results show the probable process of decreasing control of PFM activity during long-lasting contractions in symptomatic and control women. The comparison of BASE before and after training averaged the values of R after five 10-s contractions and showed an increase in the Base and decrease in the R.
