Dental caries, caused by oral microbiota, is one of the most common human diseases. The present study aimed to investigate the effect of consumption of probiotic yogurt containing Bifidobacterium lactis Bb12 on salivary Streptococcus mutans and lactobacilli in students with initial stages of dental caries. In this double-blind randomized placebo-controlled clinical trial, 66 students (18–30 years) with initial stages of dental caries were selected and randomly assigned into 2 groups: the intervention group received 300 g/day of probiotic yogurt and the control group received 300 g/day of conventional yogurt for 2 weeks. An unstimulated fasting saliva sample was collected pre- and post-intervention. Bacterial counting was performed for salivary S. mutans and lactobacilli. A significant reduction in salivary S. mutans and lactobacillus counts was observed in the intervention group compared to their baseline and compared to the control group. In conclusion, it is suggested that the consumption of probiotic yogurt containing B. lactis Bb12 may modify the oral biofilm.

IntroductionDespite being one of the first diseases to be genetically characterised, β-thalassaemia remains a disorder without a cure in a majority of patients. Most patients with β-thalassaemia receive only supportive treatment and therefore have a poor quality of life and shorter life spans. Hydroxyurea, which has shown to induce fetal haemoglobin synthesis in human erythroid cells, is currently recommended for the treatment of sickle cell disease. However, its clinical usefulness in transfusion-dependent β-thalassaemia is unclear. Here, we present a protocol for a randomised double-blind controlled clinical trial to evaluate the efficacy and safety of oral hydroxyurea in transfusion-dependent β-thalassaemia.Methods and analysisThis single-centre randomised double-blind placebo-controlled clinical trial is conducted at the Thalassaemia Centre of Colombo North Teaching Hospital, Ragama, Sri Lanka. Adult and adolescent patients with haematologically and genetically confirmed transfusion-dependent β-thalassaemia are enrolled and randomised into the intervention or control group. The intervention group receives oral hydroxyurea 10–20 mg/kg daily for 6 months, while the control group receives a placebo which is identical in size, shape and colour to hydroxyurea without its active ingredient. Transfused blood volume, pretransfusion haemoglobin level, fetal haemoglobin percentage and adverse effects of treatment are monitored during treatment and 6 months post-treatment. Cessation or reduction of blood transfusions during the treatment period will be the primary outcome measure. The statistical analysis will be based on intention to treat.Ethics and disseminationEthical approval has been obtained from the Ethics Committee of Faculty of Medicine, University of Kelaniya (P/116/05/2018) and the trial is approved by the National Medicinal Regulatory Authority of Sri Lanka. Results of the trial will be disseminated in scientific publications in reputed journals.Trial registration numberSLCTR/2018/024; Pre-results.

Abstract Background: Posterior canal benign paroxysmal positional vertigo (pc-BPPV) causes physical, functional, and emotional impairment. The treatment of choice is the Epley manoeuvre (EM). The purpose of the study was to compare the impact of the EM and a sham manoeuvre in primary care on self-perceived disability.Method: Randomised, double-blind, sham-controlled clinical trial conducted in primary care with a follow-up of 1 year. Patients aged ≥18 years old diagnosed with pc-BPPV according to the Dix-Hallpike test (DHT) were randomised to an intervention (EM) group or a control (sham manoeuvre) group. The main study covariables were age, sex, history of depression and anxiety, presence of nystagmus in the DHT, patient-perceived disability assessed with the Dizziness Handicap Inventory-screening version (DHI-S). Data were analyzed using bivariate and multivariate mixed Tobit analyses. Results: Overall, 134 patients were studied: 66 in the intervention group and 68 in the control group. Median age was 52 years (interquartile range [IQR], 38.25–68.00 years) and 76.12% of the patients were women. The DHT triggered nystagmus in 40.30% of patients. The median total DHI-S score for the overall sample at baseline was 16 (IQR, 8.00–22.00); 16 [IQR, 10.5–24.0] vs 10 [6.0–14.0] for women vs men (P<0.001) and 16 [IQR, 10.0-24.0] vs 12 [IQR, 8.0–18.0] for patients without nystagmus vs those with nystagmus (P=0.033).Patients treated with the EM experienced a mean reduction of 2.03 points in DHI-S score over the follow-up period compared with patients in the sham group. Conclusion: Pc-BPPV affects the quality of life of primary care patients. A single EM can improve self-perceptions of disability by around 2 points on the DHI-S scale, Trial registration: ClinicalTrials.gov Identifier: NCT01969513. Retrospectively registered.

Abstract Background: Attention-Deficit / Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder, characterized by varying severity in attention deficit and hyperactivity. Studies have shown deficiencies in the serum level of magnesium and vitamin D in ADHD. The aim of this study is to determine the effect of Vitamin D and magnesium supplementation on mental health in children with ADHD.Method: This double‑blind, randomized controlled trial was performed on 66 ADHD children. participants were randomly allocated to receive both Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) supplements (n = 33) or placebos (n = 33) for 8 weeks. Strengths and difficulties questionnaire were used to evaluate children’s mental health at baseline and at the end of the study.Results: After 8 weeks of intervention, the serum levels of 25‑hydroxy‑Vitamin D3 and magnesium increased significantly in the intervention group compared with the control group. Also a significant decrease in changes of emotional problems (p=0.001), conduct problems (p=0.002), peer problems (p=0.001), prosocial score (p=0.007), total difficulties (p=0.001), externalizing score (p=0.001), and internalizing score (p=0.001) was seen in intervention group at the end of study.Conclusion: Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) co-supplementation during 8-week could improve the behavioral function and mental health in ADHD. Although further well-designed studies with a larger sample size are needed.the IRCT registration: IRCT2016030326886N1.

Abstract The aim of this trial was to evaluate the efficacy of Bifidobacterium Lactis administration on infantile colic (IC). In this double blind randomized, placebo‐controlled clinical trial, infants with IC diagnosis, exclusive breastfeeding, gestational age more than 37 weeks and birth weight more than 2500 gram were included. The selected infants randomly allocated in the two groups of BBcare group, treated with Bifidobacterium animalis subsp. lactis and the control group treated with placebo, 5 drops per day, for 6 weeks. The mean of crying, vomiting episodes and defecation number at baseline and during follow ups (40 and 60 days after intervention) were compared between the two studied groups. In this study from initially enrolled neonates, 40 and 38 neonates in BB-12 and placebo groups completed the study. In BB-12 group number of defecation, crying and vomiting episodes decreased significantly during intervention till 60 days after probiotic administration(P<0.05).In the placebo group there was significant decrease for crying and vomiting episodes between baseline and 60 days after intervention(P<0.05). Between group analyses indicated that there was significant difference between groups regarding mean of crying and vomiting episodes and number of defecation ,60 days after intervention(P<0.05).Conclusion: Findings of our study offer compelling signals for the effectiveness of Bifidobacterium animalis subsp. lactis BB‐12 in the management of some intestinal problems. These findings could be supportive evidences for the important role of gut microbiota as goal of intervention to improvement in bowel movement and comfortable defecation in IC.

Abstract Objective Psoriasis is an immune-mediated inflammatory skin disease. It can involve any body skin area, particularly the scalp, lower back, elbows, and knees. There are several topical and systemic therapies for the treatment. Nowadays, herbal medicines are popular treatments for dermatologic conditions. This two-arm parallel, randomized placebo-controlled clinical trial was conducted to examine the hypothesis of the efficacy of Melissa officinalis syrup on patients with mild-to-moderate Plaque psoriasis. Result Among 100 patients, 95 participants completed the trial and five of them withdrew. The mean pruritus intensity and PASI scores decreased significantly in the intervention group compared to the placebo group (P < 0.001). The DLQI score in the intervention group increased post-treatment compared to pre-treatment (P = 0.029); however, there was no significant difference between the intervention and control group at the end of the study (0.065). Trial registration: The trial was registered in the Iranian registry of clinical trials on November 9th, 2019 (https://www.irct.ir/trial/43434; registration number: IRCT20191104045326N1).

Sinusitis is a common disease with harmful effects on the health and finances of patients and the economy of the community. It is easily treated in most of its acute stages but is associated with some management difficulties as it goes toward chronicity. Therefore, we tried to improve the treatment of subacute sinusitis by using acetylcysteine, which is a safe mucolytic and antioxidant agent. Thirty-nine adult patients with subacute sinusitis proved by computed tomography (CT) were enrolled in a double-blind, placebo-controlled trial. They received oral amoxicillin-clavulanic acid and normal saline nasal drops for 10 days and oral pseudoephedrine for 7 days. In addition, the patients received acetylcysteine (600 mg orally, once daily) in the intervention group or placebo in the control group for 10 days. A paranasal CT scan was taken at baseline and 30 days after patients finished the treatment and was evaluated quantitatively by Lund-Mackay (LM) score. Symptoms and some aspects of quality of life also were assessed at baseline and 14 days after initiation and 30 days after termination of the treatment via the Sino-Nasal Outcome Test questionnaire. The groups showed no significant difference in LM score after treatment. A positive correlation was observed between the LM and SNOT-20 scores. We concluded that adding oral acetylcysteine to amoxicillin-clavulanic acid, pseudoephedrine, and intranasal normal saline has no benefit for the treatment of subacute sinusitis.

AbstractBackgroundPremenstrual syndrome (PMS) has a high prevalence among women of reproductive ages but despite its high prevalence, it has no determined and absolute treatment, so far. So, the aim of the present study was to compare the effect Pimpinella Anisum (Anise) with placebo on the intensity of the symptoms of PMS.MethodsThe present study was a randomized double-blind controlled clinical trial. College students who were suffering from PMS and had the inclusion criteria were selected and randomly assigned into two groups of intervention (Anise) and control (placebo). Participants in the intervention group, received 110 mg capsules of Anise three times day (a total dose of 330 mg per day); the control group received similar capsules with the same dosing that contained starch. Consumption of the capsules was started 7 days before the start of the menstruation and continued until 3 days after, which was a total of 10 days during two consecutive menstruation cycles. The intensity of the symptoms of premenstrual syndrome was measured using Premenstrual Symptoms Screening Tool (PSST). To compare the intensity of the symptoms between the two study groups, generalized estimating equation statistical method was used.ResultsEventually, sixty-seven 18–35 year old college students who were suffering from premenstrual syndrome were enrolled in the study. Comparing the mean score of the intensity of the syndrome between the two groups after the first and the second menstruation cycles showed a decrease in the intervention group to 13.9 (p-value<0.001; 95% CI: 16.5,−11.4) and 9.8 (p-value<0.001; 95% CI: 12.4,−7.3), respectively.ConclusionResults of the study showed that, in general, Anise was effective in decreasing the symptoms of premenstrual syndrome in comparison to placebo.

Abstract Background : The purpose of this study was to determine the effect of a mouthwash containing Teucrium polium herb on Streptococcus mutans in mouth. Methods : This study was a randomized, crossover, double-blind clinical trial, where twenty-two volunteer dental students were randomly divided into two groups. The study had two phases. In each phase, one group was chosen as the intervention group, while the other one was the control group. Both the intervention and control groups were given the mouthwash with and without Teucrium polium , respectively. S. mutans of saliva were measured before and after each phase to compare the effects of the mouthwashes. A three-week washout period was considered between the two phases. An independent two-sample t-test was used to compare the mean number of S. mutans colonies. Additionally, a standard AB/BA crossover model was used to find the results of the treatment and the carryover effect on the residual biological effects. The significance level was considered 0.05 in this experiment. Results : There was no significant difference between the two groups in the number of S. mutans before using the mouthwashes. Using the mouthwash containing Teucrium polium extract significantly decreased the number of S. mutans colonies in both phases (P = 0.002). Conclusion : The results of this study showed that the mouthwash containing aqueous extract of Teucrium polium can significantly reduce the colonization of S. mutans in human saliva.

Background:Diabetic foot ulcer (DFU) is one of the most common complications of diabetic patients. Mostly, non-healing DFU leads to infection, gangrene, amputation and even death. High costs and poor healing of the wounds need a new treatment such as alternative medicine. So, the aim of this study was to evaluate the efficacy of Aloe vera/ Plantago major gel (Plantavera gel) in healing of DFUMethods:Forty patients with DFU enrolled in a double-blind randomized clinical trial. The patients who were randomly assigned into the intervention group (n = 20), received topical Plantavera gel in addition to the routine cares, whereas the patients in the control group (n = 20), received topical Placebo gel in addition to the routine cares. Intervention was done twice a day for 4 weeks in the both groups. Photography and an evaluation of DFU healing were conducted by a checklist and then were scored at baseline and at the end of each week. The collected data was analyzed by SPSS software.Results:At the end of the study, there was a significant difference between the two groups in terms of total ulcer score (P<0.001) and Plantavera gel significantly reduced the ulcer surface comparing with the control group (P=0.039). However, there was not a significant difference between the two groups (P=0.263) in terms of the ulcer depth. During this study, no side effect was observed for Plantavera gel in the intervention group.Conclusion:Topical Plantavera gel seems to be an effective, cheap and safe treatment. Of course, further studies are required to confirm the properties of the wound healing of this gel.
