The aim of this study is to determine the effectiveness of DentalVibe (DV) in reducing injection pain and anxiety associated with local anaesthesia in paediatric patients. The clinical trial is a randomized split-mouth assignment. Included patients are 8-12 years old requiring local anesthetic infiltration with conventional syringe (CS) for extraction of two primary maxillary molars bilaterally. Eligible patients undergo two single-visit treatments after CFSS-DS measurement before each, where as DV is allocated to either first or second local anaesthesia procedure. Primary outcome measure will be pain felt during injection, reported by patient on VAS. Secondary outcome measures: self-reported anxiety during injection on FIS; pain-related behavior according to FLACC scale; heart-rate dynamics; patient preference to local anaesthesia method - CS or CS+DV.
Pediatric chronic pain disorders are common and consequential in Western societies, occurring in 25-80% of population-based samples with a median prevalence of 11-38% and significant pain-related disability in 3-5% of these children. Pediatric chronic pain disorders have a negative impact on many aspects children's lives including mobility, night sleep, school attendance, peer relationships, family functioning, and overall quality of life. Parents caring for these children risk loss of parental earnings, and these disorders place a high financial burden on healthcare. In a nationally representative sample in the United States, costs related to health care were significantly higher ($1,339 per capita) for children with chronic pain disorders compared to children with common pediatric health conditions of ADHD, asthma and obesity. In children with clinical chronic pain conditions, such as daily headaches or fibromyalgia, chronic pain is presumably a persistent state of an overly excitable nervous system. This phenomenon known as central sensitization is characterized by excessive pain sensitivity that occurs in response to non-painful stimuli, such as light touch or contact with clothing, and slightly painful stimuli, such as a light pinprick. This hypersensitivity results from peculiar changes in the working of the central nervous system, including the spinal cord and brain, and leads to unusual intensification of pain that is out of proportion to the inciting stimulus. For example, light touch from clothing on the skin is perceived as intensely painful. Central sensitization is also thought to contribute to the spreading of pain to other body sites in several chronic pain disorders. In chronic pain disorders, the function of the central descending inhibitory modulating system is likely impaired and is traditionally measured by a phenomenon identified as "conditioned pain modulation (CPM)" and more recently measured by a phenomenon of "offset analgesia" (OA). The OA test is more robust than the CPM test and likely more acceptable to most patients, especially children, because it is shorter in duration and uses a more tolerable painful stimulus. Compared to CPM, the OA test is more tolerable because it is conducted using a painful test stimulus that is less than the maximal (suprathreshold). Additionally, the time of exposure to the painful stimulus is significantly shorter, a few seconds, in the OA test compared to CPM. The central descending inhibitory pathway that modulates pain as tested by OA is functional and mature in healthy children as young as 6 year of age, but it has yet to be investigated in children with chronic pain disorders. The investigators plan to test OA responses in a population of common pediatric pain disorders with overlapping symptomology attributed to central sensitization (such as chronic musculoskeletal pain, chronic abdominal pain and chronic headaches and chronic regional pain syndromes) and compare their responses with an age- and sex-matched control group. The characteristics of OA responses in each group will allow for assessment of the presence or absence of central sensitization as a mechanism driving the persistent, abnormal pain in a subgroup of these chronic pain disorders. The investigators hypothesize that central sensitization is the potential contributory mechanism of the central nervous system heightened sensitivity to two testing stimuli of painful (moderate heat discomfort sensation) and non-painful (warmth sensation) in children with chronic pain disorders. These types of sensations mimic those that children would be expected to experience their natural environment during typical activities of daily living such as showering/bathing in warm water or hand washing. Additionally, the Pain Sensitivity Questionnaire (PSQ) and Central Sensitization Inventory (CSI) will be used as clinical screening tools for subjective report of sensitization symptoms, and are simple and easy to administer in a clinical setting. The investigators hypothesize that these measures will correlate with the objective offset analgesia responses thus allowing for assessment of central sensitization in children with chronic pain disorders. These tests are advantageous because they are feasible to perform rapidly in a clinic setting and have utility for measurement of patient responses to therapeutic interventions. If this concept is supported by this study, future studies could utilize OA to examine the effects of various pharmacological and physical interventions used to manage children with chronic pain disorders including intensive interdisciplinary rehabilitation or specific interventions such as aerobic exercise, which likely modulates pain via similar mechanisms.
There has been little research on the third area of impairment noted in the Diagnostic and Statistical Manual of Mental Disorders - "occupational functioning." Individuals with ADHD experience job-related impairments including a greater likelihood of being unemployed and not enrolled in school and for those that were employed they were in a lower status occupation, relative to typically-developing comparison peers. The current literature on analogue workplace settings and the effects of lisdexamfetamine dimesylate includes office-based tasks similar to school seat work. Unfortunately, this is inconsistent with the typical work environment most common for individuals with disabilities such as ADHD where food preparation is the most common job following high school. Therefore, medication effects in this type of setting, most common for individuals with ADHD entering the workforce, need to be studied. The investigators propose to study workplace behavior in an analogue work setting in a laboratory "pizza place." Individuals with ADHD will participate in an interview with a supervisor each day, have a list of deliveries that need to be managed, deal with situations that require occupational judgment and appropriate customer service, and drive to make deliveries accurately and on-time. These behaviors can be reliably assessed within the laboratory. Twenty young adults will participate in two "workdays" within a randomized, double-blind, placebo-controlled design wherein participants will be administered placebo and .3 mg/kg lisdexamfetamine dimesylate in a counter-balanced order.
Family dynamics and caregiver responses to a child with traumatic brain injury are implicated both as precipitating events as well as factors influencing outcomes of abusive head trauma (AHT). However, no family behavioral health intervention exists to meet the unique needs of families with infants and very young children with AHT. The study was initially designed as a randomized controlled trial (RCT) to assess the efficacy of an evidence-based behavioral intervention to improve outcomes for families and children with AHT. However, rates of recruitment were so low that the investigators and funder amended the study to be intervention only (with IRB approval). At that time, there were five participants and only one had been assigned to the intervention arm. Only one additional family was recruited, and that family did not complete study measures prior to the time at which the intervention would start and did not receive the intervention. The investigators did examine outcomes in multiple dimensions, including clinical, cognitive, family, caregiver, child behavior, and service usage over time but connot compare to patients not receiving the intervention. The investigators were not able to examine characteristics of patients and families best suited for this behavioral health intervention.
Rationale Video Assisted Thoracic Surgery (VATS) is known to be a moderate painful procedure. There are many ways to manage postoperative pain following this kind of surgery. One of the 'golden standards' nowadays is epidural analgesia using Patient Controlled Epidural Analgesia (PCEA). Patient Controlled Intravenous Analgesia (PCIA) is also an option, as are several kinds of regional anesthesia. One of the most recent described regional blocks is the Serratus Anterior Plane block (SAP), also called Serratus Intercostal Plane (SIP) block. Objectives The objective of this study is to evaluate the efficacy and opioid sparing effect of a SIP block in postoperative pain relief after VATS. Hypotheses Patients receiving a SIP block prior to surgery need less opioids during and 24h after VATS compared with patients who didn't receive a SIP block. Study design Single center randomized controlled trial Study population Patients older than 18 years old scheduled for VATS. Main study parameters/endpoints The primary endpoint is the opioid use during the first 24 hours after start of surgery. Secondary endpoints are the VAS score on day 0 and day 1 after surgery, and the prevalence of postoperative nausea and vomiting (PONV). Nature and extent of the burden and risks associated with participation, benefit and group relatedness In the intra-operative period, patients will not experience discomfort from either strategy because of general anesthesia. If the hypothesis proves to be true, patients with SIP block could benefit from a lower amount of received opioids, which could give less chance of opioid associated adverse effects. There won't be any additional blood sampling related to this study.
Cow's milk allergy (CMA) affects up to 3% of European children. In the absence of an alternative to cow's milk, the management of CMA is based on the use of safe, affordable and nutritionally adequate formulas. In Scientific Societies Guidelines, extensively hydrolyzed casein formula (EHCF) is considered as safe first line approach for the treatment of children with CMA, whereas amino acid-based formula (AAF) is considered as second line strategy in children reacting to EHCF or as first line approach in children with CMA-induced anaphylaxis. Few and not recent studies, involving a poorly characterized study population, suggested that up to 10% of CMA children could react to the extensively hydrolysed formulas. It has been demonstrated that EHCF supplemented with L.rhamnosus GG (LGG) maintains hypoallergenic status and that is able to accelerate oral tolerance acquisition in children with CMA comparing with other formulas. The purpose of this study is to investigate the feasibility of a "step-down" approach in children affected by Immunoglobulin E (IgE)-mediated CMA with the aim to evaluate the effects of EHCF + LGG on oral tolerance acquisition and on immune response and gut microbiota shaping.
This randomized double blind study will be conducted in pregnant woman planned for non elective cesarean section under spinal anesthesia. Ketamine group will receive intravenous 0.25 mg/kg and placebo group will receive same amount of normal saline after spinal anesthesia prior to skin incision. Postoperative outcomes measures are total opioid consumption and pain scores for 24 hrs.
Some people living with health problems require extra support to properly manage their conditions, as family doctors are only able to spend limited time in the office with these patients. There are many resources and programs in the community that can provide the necessary time and support for these patients, yet many patients are unaware that such resources exist. Patient navigators have been shown to be useful in helping patients with certain conditions (such as cancer) to get to the resources they need, especially when they have social challenges that make it difficult for them to reach these programs (for example, language or transportation barriers, poverty, or poor social support). This study will look at how helpful Navigators are to link patients at family doctors' offices to community resources. To do this, family doctors' offices in Ottawa and Sudbury will be recruited. All offices will receive training on directing patients to CRs and will be assigned a patient navigator to support patients access CRs. Half of the patients referred to CRs by their providers will have access to the navigator (intervention) assigned to the practice. This study will assess whether access to a navigator increases patients' access to community health and social services compared to usual standard of care. In addition, the study aims to understand whether English and French speaking individuals are as likely to benefit from a navigator in accessing community resources in the language of their choice.
The incidence of chronic post-surgical pain (CPSP) after caesarean section (CS) is reported to be as high as 18%, reflecting it to be a significant clinical problem. Studies related to prevention of progression of acute post-CS pain to its chronicity are sparse. Current guidelines on post-CS analgesia recommend the use of intrathecal (IT) opioids to spinal anaesthesia for improved post-CS pain relief. Despite its frequent use, studies related to the IT morphine use and its association with post-CS chronic pain are lacking. A recent prospective observation study revealed a significant reduction in persistent pain after CS when IT morphine was used as an adjuvant to spinal anaesthesia. However, there is no any randomized controlled trial (RCT) that has explored this association to date. We hypothesized that spinal morphine would reduce the incidence of persistent pain after CS.
The investigators aim to understand the effect of a caffeine intake, sleep habits, anxiety about surgery, alcohol intake and smoking status upon the dose of the anaesthetic drug, propofol, required for anaesthetic induction.
