The indication for using chemical devices as an adjunct of domestic oral hygiene has gained increased attention in last decades. The efficacy of chemical devices for oral biofilm control is proven by evidence from clinical studies. The purpose of this study was to assess the effect of a new oral gel named ADC to reduce oral bacterial loading investigated by means of Polymerase Chain Reaction (PCR). Materials and methods A total of 20 patients with a diagnosis of chronic periodontitis in the age group >25 years, were selected. None of these patients had received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. The study sample was divided into two groups of 10 patients each, homogeneous by age and sex. The study group was given a little bottle containing ADC gel, while the control group was given an identical pack-containing placebo, a gel similar to ADC for consistence, colour, taste and odour. Four sites in separate quadrants were selected in each patient for testing the efficacy of the new medical device. Microbial analysis (MA) was performed at baseline and at day 15. Paired T-Test was used to detect statistical significant reduction of total bacterial loading and specific bacteria. Results Specimens of subgingival plaque from patients were investigated for the presence of six bacterial species and for total bacterial loading by quantitative PCR. There was a statistically significant reduction total bacterial loading detected pre and post treatment (p= 0.029) in the study group. In the control group the reduction of total bacterial loading was not significant (p= 0,279). The ADC gel did not show any side effects and was not observed to cause discomfort or to produce adverse reactions in time. No patient reported pain, burning, tingling sensation or numbness. Conclusion The aim of our study was to test the efficacy of a new chemical formulation with antibacterial properties to use for domestic oral hygiene with a preliminary study. Although the reported data show a statistically significant drop in total bacterial loading after treatment our limited results do not allow us to draw final conclusions about the clinical efficiency of the ADC gel. There is currently a trend in the increased use of antimicrobial agents. The effectiveness of antimicrobial therapies depends on host defence mechanisms and virulence factors. Further research, with relatively larger sample size and longer follow-up period, will be performed to better validate the efficacy of ADC gel as an effective local drug delivery agent in daily oral hygiene.

The Impact

Background: Our study aimed to assess the efficacy of 0.1% Octenidine mouthwash as an anti-plaque agent and to assess its effect on gingival inflammation and staining of teeth when compared to 0.2% chlorhexidine gluconate by evaluating the impact on plaque and gingival inflammation as well as on microbial load. Materials and Methods: A three week double blind study was conducted on 69 subjects, aged 20-50 years, with moderate to severe gingivitis. The study population was divided into three groups with 23 subjects in each group: Group A - control subjects received only scaling, Group B received 0.2% chlorhexidine gluconate in addition to scaling and Group C received 0.1% Octenidine mouthwash along with scaling. Clinical and microbiological parameters were recorded at baseline, on 14th day and on 21st day. Subjective and objective criteria were assessed on the 14th day and 21st day. Results: There was a statistically significant reduction in all the tested parameters within all the three groups and between the groups from baseline to 21st day. The highest mean reduction in all the parameters was seen in subjects using 0.1% Octenidine. On comparison with the control group, subjects using the mouthwashes (Group B and Group C) had better improvement in clinical and microbiological parameters from baseline to 21st day. On comparison with chlorhexidine, Octenidine mouthwash significantly reduced plaque (p<0.05) and showed better patient acceptability. However, it was comparable to chlorhexidine in other two tested parameters. Conclusion: Owing to Octenidine’s pronounced and comparable antibacterial properties, it can be a promising candidate for the use in antiseptic mouthwashes.

Aim: Diabetic symmetrical peripheral neuropathy is a common complication of diabetes mellitus. Patients treated with transcutaneous CO2 application for chronic wounds reported an improvement in peripheral sensations. This study aimed to evaluate the effect of transcutaneous application of gaseous CO2 on diabetic symmetrical peripheral neuropathy. Methods: A prospective randomized, double-blind study was performed at the University Medical Center Ljubljana between September 2019 and September 2020. Sixty consecutive patients with diabetes with a unilateral chronic wound were randomized into either a study group that received transcutaneous CO2 therapy or a control group that received placebo treatment with air. Results: Vibration, monofilament sensation, and temperature of the big toe improved significantly in the study group (p < 0.001, for vibration sensation, monofilament test and temperature of the big toe), but not in the control group (p = ns for all evaluated outcomes). Conclusion: According to our results, a transcutaneous application of gaseous CO2 shows promising results in treating diabetic symmetrical peripheral neuropathy. Considering the major consequences of sensory loss leading to foot ulceration and possibly amputation, we believe this treatment approach deserves future attention and investigation as a treatment modality of diabetic symmetrical peripheral neuropathy.

The aim of this study was to evaluate the clinical and microbiological effects of subgingival instrumentation (SI) alone or combined with either local drug delivery (LDD) or photodynamic therapy (PDT) in persistent/recurrent pockets in patients enrolled in supportive periodontal therapy (SPT). A total of 105 patients enrolled in SPT were randomly treated as follows: group A (n = 35): SI +PDT and 7 days later 2nd PDT; group B (n = 35): SI+LDD; group C (n = 35): SI (control). Prior intervention, at 3 and 6 months after therapy, probing pocket depths, clinical attachment level, number of treated sites with bleeding on probing (n BOP), full mouth plaque and bleeding scores (gingival bleeding index, %BOP) were recorded. At the same time points, 8 periodontopathogens were quantitatively determined. All three treatments resulted in statistically significant improvements (p < 0.05) of all clinical parameters without statistically significant intergroup differences (p > 0.05). Several bacterial species were reduced in both test groups, with statistically significantly higher reductions for LDD compared to PDT and the control group. In conclusion, the present data indicate that: (a) In periodontal patients enrolled in SPT, treatment of persistent/recurrent pockets with SI alone or combined with either PDT or LDD may lead to comparable clinical improvements and (b) the adjunctive use of LDD appears to provide better microbiological improvements for some periodontal pathogens than SI alone or combined with PDT.

The aim of this study was to evaluate the effect of toothpaste containing natural tea tree essential oil (TTO) and ethanolic extract of propolis (EEP), on microflora and selected indicators of oral health in patients using removable acrylic partial dentures. Fifty patients with varying conditions of hygiene were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. At the first visit, oral hygiene and hygiene of the prostheses were carried out. Control visits took place 7 and 28 days later and compared to baseline. Indexes like API (Approximal Plaque Index), mSBI (modified Sulcus Bleeding Index), OHI-s (simplified Oral Hygiene Index), and DPI (Denture Plaque Index) were assessed in three subsequent stages, and swabs were collected from floor of the mouth area to assess the microbiota. After 7 and 28 days of using the toothpaste with TTO and EEP, a statistically significant decrease of the examined indicator values were observed in the study group as compared to the values upon the initial visit. The number of isolated strains of microorganisms in the study group was decreased or maintained at the same level, whereas in the control group an increase in the number of isolated strains was observed. The observed stabilization of oral microbiota in patients from the study group confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group.

Introduction: The aim of current paper was to compare the effectiveness of acceptance and commitment group therapy (ACT) and group cognitive therapy (GCT) on Alexithymia and marital boredom (MB) among women affected by marital infidelity in Mashhad. Method: This clinical trial was a double- blind study with a pretest-posttest design in which two intervention groups and one control group were investigated. The study performed on women who realized their spouse infidelity and referred to Azad University Counseling Center in Mashhad in 2018. The sample consisted of 30 women who were selected by purposive sampling and were randomly assigned to two intervention groups and a control group (n=10 per group). The intervention groups were put under ACT training (twelve 90-minute sessions) and GCT training (twelve 90-minute sessions), but the control group did not receive any intervention. Data was obtained by the Toronto Alexithymia Scale-20 and Pines Marital Boredom Scale and was analyzed by multivariate analysis of covariance with SPSS (version 22) software. Results: The results showed a significant reduction in the mean score of MB in the ACT group, also there was a significant reduction in the mean score of Alexithymia in the GCT group (P <0.05). So comparing both therapies, ACT was more influential on reducing marital boredom whereas GCT was more effective on reducing alexithymia. Conclusion: Although both intervention methods were effective on Alexithymia and Marital Boredom in women affected by marital infidelity, it was demonstrated that ACT and GCT have more effect on Marital Boredom and Alexithymia, respectively.

Effective Analgesia

Background The intrathecal combination of sufentanil and bupivacaine provides rapid, effective analgesia for labor with a limited duration. Many anesthesiologists have concerns that the use of intrathecal local anesthetics precludes maternal ambulation. This prospective, randomized, double-blind study was designed to determine whether the addition of epinephrine to the combination of sufentanil and bupivacaine would prolong intrathecal analgesia for labor. Patients' ability to ambulate was also assessed. Methods Thirty-nine patients received either an intrathecal control dose of 10 micrograms sufentanil plus 2.5 mg bupivacaine plus 0.2 ml normal saline (control group); or 10 micrograms sufentanil plus 2.5 mg bupivacaine plus 0.2 ml (0.2 mg) of epinephrine (EPI group). Results Seven patients (3 control, 4 EPI) delivered vaginally and two (1 control, 1 EPI) required cesarean delivery before requesting epidural analgesia. The duration (mean +/- SD) of intrathecal labor analgesia was prolonged significantly by the addition of epinephrine: control (n = 15): 145 +/- 23 min; EPI (n = 15): 188 +/- 25 min (P &lt; 0.0001). Maternal ambulation was demonstrated in 100% (19 of 19) of the control group and in 80% (16 of 20) of the EPI group (P = NS). Conclusions The addition of 0.2 mg epinephrine to the intrathecal combination of sufentanil and bupivacaine significantly prolonged labor analgesia without causing adverse effects to the mother or fetus. The intrathecal combination of sufentanil and bupivacaine, with or without epinephrine, provided rapid, profound labor analgesia and allowed most patients to ambulate.

Background: Pain is one of the most common complications after tooth extraction and pain control is a crucial part of the procedure. The purpose of this study was to investigate the influence of 0.2% (w/v) chlorhexidine (CHX) gluconate mouth rinse on the severity of post-extraction pain. Methods: A prospective, randomized, double-blind trial was conducted among 170 subjects. Subjects were instructed to rinse with 15 mL of CHX mouth rinse (study group) or placebo (control group) 0.5 to 1 hour before extraction. Post-operative pain was evaluated considering the number of taken rescue analgesics and using a visual analog scale (VAS) that each case completed 6, 12, 24, and 48 hours after the surgery. The Mann-Whitney U test was performed in this regard. Results: There were no significant differences between the two groups regarding demographic variables (P>0.05). The preoperative use of CHX mouth rinse showed a better performance in mitigating the perceived pain. A significant difference in the pain level (P=0.001) was found only at the 6th hour postoperatively although there was no significant difference in the pain level between the two groups (P>0.05) at all other times (12th, 24th, 48th hours). The total number of analgesics that were taken by the study group was significantly lower compared to the control group (P=0.042). Conclusions: The preoperative CHX mouth rinse could be a beneficial choice for reducing pain after simple tooth extractions.

Background: Although revascularization treatment is recommended as the first-line therapy for patients with non-minor acute ischemic stroke (AIS), it only benefits a minority of patients. Previous studies have reported the positive effects of Panax notoginseng saponins (PNS) (Xueshuantong lyophilized powder) on AIS, however, there have been no rigorous trials. This study aims to assess the efficacy and safety of PNS therapy for patients with AIS.Methods: The Evaluation of Xueshuantong in Patients with acutE ischemiC sTroke (EXPECT) trial is a multicenter, randomized, placebo-controlled, double-blind study aiming to enroll 480 patients in China. Eligible patients with AIS within 72 h of symptom onset will randomly receive either PNS or PNS placebo for 10 days and subsequently be followed up to 90 days. The primary outcome will be a change in the National Institute of Health Stroke Scale (NIHSS) score from baseline to 10 post-randomization days. The secondary outcomes include early neurological improvement (proportion of patients with NIHSS score 0–1), and Patient-Reported Outcomes Scale for Stroke score at 10 post-randomization days, the proportion of patients with life independence (modified Rankin Scale score of 0–1), the proportion of patients with a favorable outcome (Barthel Index ≥90), and Stroke-Specific Quality of Life score at 90 days. Adverse events or clinically significant changes in vital signs and laboratory parameters, regardless of the severity, will be recorded during the trial to assess the safety of PNS.Conclusions: To our knowledge, this study is the first double-blind trial to assess the efficacy and safety of PNS in patients with AIS. Findings of the EXPECT trial will be valuable in improving evidence regarding the clinical application of PNS therapy in patients with AIS ineligible for revascularization treatment in the reperfusion era.
