Filter by:Approximately 2-3% of children will have problems with one or both of their permanent or 'adult' canine teeth in the upper jaw. These canine teeth sometimes fail to erupt properly, because they are displaced into the roof of the mouth or palate. These are known as palatally displaced canines, PDC, (Brin et al., 1986, Ericson and Kurol, 1987). In addition to failing to erupt, displaced teeth can cause problems, such as damage to the roots or displacement of the neighbouring teeth (Ericson and Kurol, 1988a, Ericson and Kurol, 2000, Falahat et al., 2008). It has been suggested that if the primary ('baby' or 'milk') canine is extracted at an appropriate time in a child with a suspected palatally displaced canine, then the displaced tooth might spontaneously correct its position (Ericson and Kurol, 1988b) and the extraction of the baby canine when a clinician suspects that the adult canine is displaced has become accepted clinical practice (Short, 2009). This appears to be on the basis of one report of a series of 35 children who received the intervention and no control group (Ericson and Kurol, 1988b). Two recent systematic reviews have examined the evidence for the effectiveness of removal of the primary canine with the aim of correcting the eruption path of a palatally displaced canine. A recent systematic review published in The Cochrane Library in 2021 (Benson et al., 2021) noted that the evidence for any intervention to correct the eruption path of a displaced permanent canine is weak and further research is required. Numerous problems with the reported studies were identified by both reviews. Other authors have suggested that using a RME (Rapid Maxillary expansion) or headgrear (EOT) to create sufficient space within the dental arch for the permanent canine tooth will encourage the tooth to erupt (Baccetti et al., 2011). This approach might be less traumatic to a child who may have had no experience of dental treatment, other than routine check-ups. If either or both approaches are shown to be effective then their widespread use would be advantageous to both the child and the healthcare provider, because the need for an operation, under general anaesthetic, to uncover the tooth and extensive brace treatment to straighten the tooth will be avoided.
Problematic mobile phone use (PMPU) has been described as a growing public health issue. This randomized controlled trial aimed to determine if aerobic exercise or Tai Chi Chuan as compared to the wait-list control group decreased PMPU-related symptoms; and to analyze the composition of the intestinal flora in the three study groups to explore the correlation between PMPU scores and flora species. A consecutive sample of 90 college students with PMPU was randomized to the aerobic exercise group (AE group, n = 30), the Tai Chi Chuan group (TCC group, n = 30), or the wait-list control group (WLC group, n = 30). The primary outcome was addiction symptoms, i.e., the PMPU score as assessed by the Smartphone Addiction Scale-Short Version (SAS-SV). Secondary outcomes were the emotion-related symptoms (depression, anxiety, self-esteem and self-efficacy), and physical-related symptoms (sleep quality, physical-fatigue and mental-fatigue). Intervention effects were analyzed via generalized estimated equation analysis (GEE).
Internet addiction disorder (IAD) is an impulse-control disorder of Internet behavior in the absence of addictive substances. Exercise has been found to have significant advantages in improving the severity and depressive symptoms of IAD. The purpose of this study was to observe the efficacy of conventional exercise and tai chi in the treatment of Internet addiction and to observe the changes in each group. Subjects diagnosed with IAD were randomly assigned to the exercise group, the tai chi group, or the control group. The exercise group and tai chi group received conventional exercise and tai chi for 8 weeks. The Internet Addiction Test (IAT), the Pittsburgh sleep quality index (PSQI), the Zung Self-rating Depression Scale (SDS), the Zung Self-rating Anxiety Scale (SAS), and Fatigue Scale-14 (FS-14) were evaluated for all subjects at baseline and postintervention.
The purpose of this study is to compare blood levels of women who take commericially available, low dose docosahexaenoic acid (DHA) dietary supplements in pregnancy with women who do not take supplements.
COVID-19 is an emerging pandemic disease caused by severe acute respiratory syndrome (SARS-CoV-2). Although the majority of patients infected with SARS-CoV-2 are asymptomatic or have mild symptoms, some patients develop severe symptoms that can protractedly impair their quality of life and functional capacity. SARS-CoV-2 is closely related to severe acute respiratory syndrome (SARS) with direct and indirect effects on several systems, especially the musculoskeletal system, in addition to the respiratory system. Some of these symptoms persist for a long period, called Post-Covid-19 Syndrome, directly interfering with the functional capacity and quality of life of these participants. Cardiopulmonary Rehabilitation exercises are focused on restoring functional capacity in patients affected by cardiopulmonary diseases. The primary objective of this study is to evaluate the clinical and functional effects of a quarterly Cardiopulmonary Rehabilitation exercise program for participants with post-COVID-19 syndrome. The secondary objectives will be: To compare the effects of a supervised program of 12 weeks of supervised exercises and a program of self-performed home exercises, guided by an exercise booklet, of the same duration on muscle strength and peripheral resistance; Compare the effects of a 12-week supervised exercise program and a self-performed home exercise program, guided by an exercise booklet, of the same duration on levels of fatigue and dyspnea in patients with post-COVID-19 syndrome; Compare the effects of a 12-week supervised exercise program and a self-performed home exercise program, guided by an exercise booklet, of the same duration on health-related quality of life and post-COVID-19 functional status.
A single blinded randomized controlled trial. 212 subjects (teeth), 106 in each of the 2 groups will be recruited from the patients referred to Kuwait Board of Endodontics for primary root canal treatment. The aim is to compare the outcome of sealer-based obturation (SBO) with calcium silicate sealer versus warm vertical compaction (WVC) and resin based sealer. Preoperative PA radiograph and CBCT will be taken. A 1 year follow up period will be arranged and another PA radiograph and CBCT will be taken. The preoperative, postoperative and review clinical and radiographic data will be analyzed
ACTIVA BioACTIVE products are allegedly the first dental resins with a bioactive ionic resin matrix, shock-absorbing rubberized resin component, and reactive ionomer glass fillers that mimic the physical and chemical properties of natural teeth. These bioactive materials actively participate in the cycles of ionic exchange that regulate the natural chemistry of our teeth and saliva and contribute to the maintenance of tooth structure and oral health. They are claimed to have the strength, esthetics and physical properties of composites and are more bioactive than glass ionomers, combining the best attributes of both materials without compromising either one.
The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.
Acute malnutrition affects 51 million children under the age of 5 worldwide. Malnutrition contributes to nearly half of all child deaths each year, with the forms characterized by wasting or oedema (acute malnutrition) associated with the highest risk of death. Although acute malnutrition is a continuum condition, it is arbitrarily divided into severe and moderate acute malnutrition (SAM, MAM) which are managed separately, with programs overseen by different UN agencies, and using different protocols and products. Such separation complicates delivery of care, contributes to high default and low coverage, and creates confusion among caregivers. Often treatment is only available for SAM children resulting in lives lost and costly hospitalisation that could be averted if nutritional support were available earlier in the wasting process. If we are to reduce the health and mortality burden from malnutrition, the effectiveness and cost-effectiveness of current protocols need dramatic improvements. The dosage of Ready to Use Therapeutic Food (RUTF) for SAM (130-200 kcal/kg/d) has not changed since introduction of out-patient protocols in the mid-2000s. Children classified as SAM in these protocols are determined by three independent criteria: the presence of nutritional oedema or MUAC < 115 mm or weight-height Z score <-3. The RUTF dosage in these protocols is paradoxical in that the absolute amount of RUTF prescribed in the initial phases of treatment is often less than that given as the child nears recovery, because the number of packets in the weekly ration is determined by weight. However, rate of weight gain (g/kg/day) is highest in the first two weeks of treatment, and then plateaus - suggesting no benefit of increased RUTF amounts in the later phases of treatment. Progressive reduction seems to be a more rational use of RUTF. The Optimizing treatment for acute MAlnutrition (OptiMA) strategy consists in simplifying management of acute malnutrition through the use of a single anthropometric admission criterion (mid upper arm circumference [MUAC] < 125 mm or nutritional oedema) - one that best captures children's anthropometry related mortality risk- and by optimizing the use of RUTF by adapting doses to the nutritional recovery of the child. RUTF doses begin at 170 kcal/kg/d for the most severely wasted (MUAC < 115 mm or oedema) and reduce to 75 kcal/kg/d as oedema resolves and MUAC increases > 120 mm. The investigators hypothesize that this strategy could double the number of children in care compared to current SAM programs without substantially increasing the amount of RUTF or staffing required while maintaining a recovery rate in line with current programs. OptiMA may also improve coverage and reduce the need for hospitalization through early identification of malnourished children. The investigators propose to conduct a community-based non-inferiority clinical trial with individual randomization comparing the OptiMA strategy to the Democratic Republic of Congo standard nutritional protocol for SAM. Study children will be randomly assigned to the intervention arm or control arm - with children at MUAC < 125 mm or oedema eligible for RUTF in the intervention arm and those meeting current WHO SAM definition eligible in the control group. All participants will be followed for 9 months post-randomization to assess non-inferiority as defined by a composite of three endpoints : alive, acceptable nutritional status (MUAC ≥ 125 mm and WHZ >-3, no oedema) and no relapse to acute malnutrition for those who were treated with RUTF. The main secondary outcome will assess the non-inferiority of OptiMA RUTF dosing (170 kcal/kg/d) in children meeting current WHO SAM criteria compared to children with the same criteria in the control arm who will receive 130-200 kcal/kg/d.
