Adjunctive therapeutic strategies that modulate the inflammatory mediators can play a significant role in periodontal therapy. In this double-blind, placebo-controlled study, 60 subjects diagnosed as periodontitis patients were evaluated for 28 days after periodontal treatment combined with selective cyclooxygenase-2 (COX-2) inhibitor. The experimental group received scaling and root planning (SRP) combined with the Loxoprofen antiinflammatory drug (SRP+Loxoprofen). The control group received SRP combined with placebo (SRP+placebo). Plaque index (PI), probing pocket depth (PD) and bleeding on probing (BOP) were monitored with an electronic probe at baseline and after 14 and 28 days. Both groups displayed clinical improvement in PD, PI and BOP. They also showed statistically similar values (p>0.05) of PD reduction on day 14 (0.4 mm) and on day 28 (0.6 mm). At the baseline, few deeper sites (>7 mm) from SRP+Loxoprofen group were responsible and most PD reduction was observed after 14 days (p<0.05). The percentage of remaining deep pockets (>7 mm) after 14 days in the SRP+Loxoprofen group was significantly lower (p<0.05) than in the SRP+placebo group. Loxoprofen presents potential effect as an adjunct of periodontal disease treatment, but long-term clinical trials are necessary to confirm its efficacy.

Abstract Background The purpose of this study was to investigate gingival crevicular fluid (GCF) and serum folate-receptor 1 (FOLR1) levels in subjects with different periodontal status. Methods The study consists of three groups: Healthy group (n = 15), gingivitis group (n = 15) and chronic periodontitis group (n = 15). Clinical periodontal parameters including probing pocket depth (PPD), clinical attachment level (CAL), gingival index (GI) and bleeding on probing (BOP) were assessed. GCF and serum samples were collected from each patient and were analyzed FOLR1 levels by enzyme-linked immunosorbent assay. Results The values of FOLR1 in GCF were higher in gingivitis and periodontitis groups than among patient in control group (p < 0.016). Serum FOLR1 levels showed no significant difference between the groups. A significant correlation was observed between FOLR1 levels of GCF and BOP (p < 0.05). Conclusions Our preliminary data suggest that FOLR1 is not useful in monitoring the periodontal disease. Further studies are necessary to clarify the role, regulation and function of folate and it’s receptors in the pathogenesis of periodontal disease.

Background: Magnesium sulphate has been used successfully as a non opioid analgesic adjuvant for postoperative pain management. This prospective controlled study was designed to evaluate the pre-emptive analgesic efficacy of adding magnesium to epidural analgesia in patients undergoing lower abdominal surgeries.Methodology: In a randomized, double- blind study sixty patients undergoing lower abdominal surgery under general anesthesia were assigned to three groups. Pre-magnesium (Group PI), post-magnesium (Group PO) and control (Group C) group. Anesthetic technique was standardized. Patients in pre-magnesium group received bolus of magnesium 50 mg via epidural before induction of anaesthesia followed by boluses of 10 mg h-1 until end of surgery. Post-magnesium group patients received epidural saline during the same time periods plus bolus epidural magnesium 50 mg at the end of surgery. Patients in control group received epidural saline during all three periods. Patients in the magnesium groups received bolus epidural analgesia with Fentanyl 8mcg, Bupivacaine 0.1%, and Magnesium 8mg in a volume of 8 ml after operation, when patient complained of pain and VAS score was more than 4. Patients in the control group received epidural analgesia with Fentanyl 8 mcg and Bupivacaine 0.1% in a volume of 8ml. Blood Pressure, pulse rate, respiratory rate, time to the first request for analgesic, visual analogue scale at rest, 24 hour, opioids consumption and side effect profiles were studied for 24 hours postoperatively.Results: The demographic parameters were comparable. Group PI had significantly lower VAS scores at all times 0,2,4,6,10,14,18 and 24 hours than those in the Group PO or Group C(P<0.05). The groups were similar with respect to haemodynamic, respiratory variables and side effects.Conclusion: Epidural Magnesium sulphate provided preemptive analgesia, and an a analgesic-sparing effect that improved postoperative analgesia without increasing the incidence of side-effects.Journal of Society of Anesthesiologists 2014 1(1): 22-28

Introduction and objective: Chronic periodontitis is the most common form of periodontal disease. Progression of the disease is due to high levels of pro-inflammatory cytokines. Statins are a class of lipid-lowering drugs that used for cardiovascular disease and stroke. Statins has potential anti-inflammatory effect by blocking intermediate metabolites of the mevalonate pathway. The aim of this study was to evaluate the influence of Lovastatin and Simvastatin in improve the parameters of chronic periodontitis in the population of Khorasan Razavi province. Methods and materials: 40 subjects with chronic periodontitis were selected and informed consent was obtained from participants. Participants were divided into control and experimental groups and we scaling for patients of both groups, then control group without high blood cholesterol and treatment of patients was done without statin drugs and in case groups, patients with blood cholesterol higher than 240 mg/dl with Lovastatin 20 mg/day during 3 month treated. Periodontal indices; such as probing pocket depth (PPD), GI, PI, CAL and bleeding on probing in patients with chronic periodontitis were measured by the examiner before and after treatment in the control group and the experimental group. Also this index were measured 3 months after treatment in both groups by the same person examiner as Blind and dataes were analyzed by statistical software. Results: In this study, Mean ± SD of age was 7.93 ± 43.8 in the control group and the experimental group was 7.72 ± 47.8 and of the 40 patients in the study, 18 were males and 22 were females. Our study showed that the index of GI, CAL, BOP and probing depth were significantly different between the two groups after the intervention (P less than 0.05) and only after the intervention PI index was not significantly different between the two groups (P>0.05). Conclusion: Our findings showed that statins may improve periodontal index in patient with periodontal disease. This is probably because that statins increase bone regeneration and reduced inflammatory parameters such as CRP, MMP-9, TNF-α and the intermediate products.

Background: periodontitis is a chronic inflammatory disease causing destruction of the tooth supporting structures, initiated by dental plaque and modified by environmental and genetic risk factors. Cyclooxygenase-2 (COX-2) enzyme is responsible for the production of prostaglandin E2, an important mediator in the chronic periodontitis (CP) pathogenesis. Polymorphisms in COX-2 gene have linked to CP in different populations. Aim: To study the association between Cyclooxygenase-2 single nucleotide polymorphism rs689466 (-1195A/G SNP) and chronic periodontitis in a sample of Iraqi population. Methods: One hundred Iraqi subjects divided into two groups: case group consisted of 70 CP patient (35 males and 35 females) with age range 30-55 years, and control group consisted of 30 racially matched healthy subjects (15 males and 15 females) with age range 30-50 years. Clinical periodontal parameters including plaque index (PLI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment level (CAL) were recoded for all participants. 3ml of venous blood was collected from each participant for isolating genomic DNA. Genotyping of the rs689466 in COX-2 gene was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: The frequency of G allele carriers was significantly more prevalent in the case group compared to control group (P= 0.041), and allele G was associated with greater susceptibility for chronic periodontitis compared to allele A (OR=1.4). Conclusion: COX-2 (rs689466) polymorphism may be associated with increased chronic periodontitis susceptibility.

AbstractBackgroundThe neuromodulation induced by neurofeedback training (NFT) remains a matter of debate. Investigating the modulation of brain activity specifically associated with NF requires controlling for multiple factors, such as reward, performance, congruency between task and targeted brain activity. This can be achieved using sham feedback (FB) control condition, equating all aspects of the experiment but the closed-loop between brain activity and FB.ObjectiveWe aimed at investigating the modulation of individual alpha EEG activity induced by NFT in a double-blind, randomized, sham-controlled study.MethodsForty-eight healthy participants were assigned to either NF (n=25) or control (n=23) group and performed 12 NFT sessions of alpha upregulation with a wearable EEG device. Participants of the NF group received FB based on their individual alpha activity. The control group received the auditory FB of participants of the NF group.ResultsAn increase of alpha activity across training sessions was observed in the NF group only (p<0.001). This neuromodulation was selective in that it was not observed for theta (4-8Hz) and low beta (13-18Hz) activities. It was associated with an increased feeling of control (p<0.001), more marked for NF than control group. Anxiety level decreased and relaxation feeling increased with training in both groups.ConclusionsNFT across multiple sessions can induce specific brain modulation, suggesting a neuroplasticity selective of the targeted brain activity. Our results pave the way to self-learnt, NF-based neuromodulation with light-weighted, wearable EEG systems for various applications (e.g. epilepsy, sleep, attention).HighlightsRandomized double-blind study of neuromodulation induced by EEG-neurofeedback (NF)Sham feedback (FB) was used for the control groupTargeted alpha activity increased selectively over the 12 NF training sessionsThis neuromodulation was observed only in the real NF training groupThe feeling of control across sessions increased more for real than sham FB group

Background: Hypertension is probably the most important public health problem around the world. People with periodontal disease may be at greater risk of hypertension. The inflammatory effects of periodontal disease help to promote endothelial dysfunction in arteries which may lead to changes in blood pressure. Salivary MMP-8 has been associated with both periodontal disease and prevalent hypertension. Aim of study: This study was conducted to measure salivary matrix metalloproteinase - 8, in relation to periodontal health condition among a group of patients with hypertension in comparison with control group. Materials and methods: Ninety subjects, aged 45-50 years old were included in this study, seeking treatment for chest pain in Ibn-AlBaytar center for cardiac surgical treatments in Baghdad, Iraq. The subjects were divided into study group (45 patient) who were diagnosed to be a hypertensive patient, and a control group (45 subject), with no hypertension. Plaque status was evaluated according to the Silness and Loe, probing pocket depth and clinical attachment level. Unstimulated saliva was collected from all subjects to analyses MMP-8. Result: A high mean value of plaque index, clinical attachment level and probing pocket depth for the study group than the control group with statistically no significant difference. In addition to that, a significant positive correlation between the plaque index and the clinical attachment level among both groups. Salivary MMP-8 level showed a higher level in the study group than in the control group, with statistically significant difference between groups, and a significant positive correlation was detected between salivary MMP-8 with plaque index, among study group, Conclusions: Higher percentage of periodontal diseases was found among patients with blood hypertension. In addition, high level of salivary MMP-8 is potentially associated with periodontal status of the study group.

Background: This study assessed the effects of weekly vitamin D (VD) supplementation on clinical and biological parameters after scaling and root planning (SRP) in the treatment of periodontitis and served to validate the VD dosage regimen. Methods: It was a monocentric, randomized, double-blind, placebo-controlled clinical trial with 6 months follow-up. Healthy Caucasian periodontitis patients presenting serum 25(OH) vitamin D3 below 30 ng/mL were randomly allocated to test group (SRP + VD 25,000 international units (IU)/week) or the control group (SRP + placebo). Results: A total of 59 patients were screened, 27 were included and 26 completed 3 months (M) and 21 completed 6M control. Test (n = 13) and control groups (n = 14) had similar 25(OH) vitamin D3 levels at baseline (17.6 ± 7.4 vs. 14.4 ± 5.2, respectively). After one month, there was a significant difference between groups (32.9 ± 5.2 vs. 16.1 ± 4.7), also seen at M3 and M6 (t-test, p < 0.001). Periodontal treatment was successful in both groups, since it resulted in a reduction of all measured clinical parameters at M3 and M6 (probing pocket depth (PPD), full mouth bleeding and plaque). However, the reduction in PPD was greater in the test group. Conclusions: In this short-term pilot study, no significant differences were observed between two groups. However, supplementation with VD tended to improve the treatment of periodontitis in patients with initial 25(OH) vitamin D3 < 30 ng/mL and proved safe and efficacious. NCT03162406.

Loop ileostomy closure after colorectal surgery is often associated with Postoperative ileus, with an incidence between 13–20%. The aim of this study is to evaluate the efficacy and safety of preoperative stimulation of the efferent loop with probiotics prior to ileostomy closure in patients operated on for colorectal carcinoma. For this, a prospective, randomized, double-blind, controlled study is designed. All patients who underwent surgery for colorectal carcinoma with loop ileostomy were included. Randomized and divided into two groups, 34 cases and 35 controls were included in the study. Postoperative ileus, the need for nasogastric tube insertion, the time required to begin tolerating a diet, restoration of bowel function, and duration of hospital stay were evaluated. The incidence of Postoperative ileus was similar in both groups, 9/34 patients stimulated with probiotics and 10/35 in the control group (CG) with a p = 0.192. The comparative analysis showed a direct relationship between Postoperative ileus after oncological surgery and Postoperative ileus after reconstruction surgery, independently of stimulation. Postoperative ileus after closure ileostomy is independent of stimulation of the ileostomy with probiotics through the efferent loop. There seem to be a relationship between Postoperative ileus after reconstruction and the previous existence of Postoperative ileus after colorectal cancer surgery.

The progression of periodontitis may be affected by ALDH2 genotypes with respect to the oxidation of acetaldehyde to acetate, which leads to the accumulation of acetaldehyde in plasma and potential toxic effects. We examined the prospective association of ALDH2 genotypes in terms of alcohol sensitivity between alcohol consumption and periodontal disease progression. In 2003, 224 of 256 (87.5%) individuals examined at baseline (1999) completed probing pocket depth measurements for the evaluation of periodontitis progression. Missing data on self-reported questionnaires and blood samples were excluded; therefore, 183 samples were analyzed. Individuals who consumed ≥ 33.0 g/day of alcohol exhibited high periodontal disease progression risk (OR = 3.54). ALDH2 *1/*2 individuals who consumed ≥ 33 g/day of alcohol displayed a significant odds ratio (OR = 4.28) of periodontitis progression risk, in contrast to ALDH2 *1/*1 individuals. These results suggested that alcohol consumption as well as alcohol sensitivity may be a risk factor for periodontitis progression.

To evaluate the effect of injections of gamma-globulin upon the course of asthma, observations were made with 22 asthmatic children ranging in age from 1½ to 5½ years. They had suffered from asthma from 1 to 13 years and were selected as subjects because they had not made satisfactory improvement under allergic management over an average of 2.4 years. They were placed in two groups by random assignment, one of which received injections of gamma-globulin. Without knowledge of the treatment being given, one author examined each child at the time of each injection and one month after the last injection. Roentgenograms, vital capacity, complete blood counts and chemical determination of the blood proteins were performed at the initial and final visits. Fifteen of the twenty-two patients improved clinically, eight in the treatment group and seven in the control group. No significant differences between the groups were noted in the amount of asthma, physical growth, hemoglobin value or eosinophilia. The concentration of gamma-globulin in the serum increased in the treated patients. Nevertheless, there was no difference in the incidence of infection in the two groups and in both it was equal to that in a normal population. This double-blind controlled study offers no evidence to support the view that treatment with gamma-globulin has a beneficial effect on the course of chronic asthma in children.
