Active clinical trials for "Headache"

Headache is a common symptom, and patients often seek medical attention at emergency departments due to headaches. The aim of the CoHead Study is to find out if it is possible by measuring copeptin, a marker of stress in the blood, to find out which patients have simple headaches and which patients have dangerous headaches that are the symptom of an underlying disease and need further investigation and treatment. Copeptin is a marker for physical stress and has been tested in patients with stroke, heart attack and pneumonia. In all these illnesses, the patients with the most serious forms had the highest levels of copeptin, while the ones with only mild presentation or no affection at all had the lowest levels of copeptin. The investigators expect to show the same in patients with headaches.

One way to better understand how various treatments for pain differ is to determine the effects of these treatments on different pain qualities or characteristics. For example, pain can be described as "hot", "electrical", "cold", "achy", and "piercing." In order to determine which pain quality/qualities that a pain treatment affects, researchers must develop measures of these pain qualities or characteristics. The purpose of this study is to learn more about the different pain qualities individuals who have low back pain, headaches and fibromyalgia experience. Identifying the common qualities of pain experienced by these groups will help researchers evaluate and develop more comprehensive pain quality measures, which will ultimately help them to be able to test the effectiveness of treatments for these different pain qualities.

Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: To determine the parts of the brain involved in suppressing an urge to act. To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: This research study includes a screening visit and two study visits, each of which will last at least 2 hours. Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

To investigate headache score and accompanying symptoms during and after inhalation of carbon monoxide.

Postoperative headache is a major issue after general anaesthesia and surgery. The aim of this study is to investigate the possible difference in the occurrence of postoperative headache when general anaesthesia is maintained with propofol, which is supposed to have protective effects on migraine patients, versus sevoflurane.

Neuraxial techniques are widely used in obstetric practice to provide analgesia and anesthesia. A common complication associated with neuraxial anesthesia is post-dural puncture headache (PDPH), resulting from unintentional or unintended puncture of the dura mater during insertion of an epidural needle. Incidence of PDPH after spinal anesthesia is very low due to the widespread use of non-cutting small diameter spinal needles. Incidence of "wet tap" during epidural injection has been reported to be 1.5%, with 52-85% of these patients developing PDPH. When an obstetric patient develops PDPH, institution of an effective treatment is necessary. Although PDPH tends to resolve spontaneously over a couple of weeks, it carries the risk of potential complications. PDPH interfere with the ability of the mother to take care of her baby, increases the risk of chronic headache and limits early ambulation, thereby increasing the risk of venous thrombosis and pulmonary embolism. As important as treating PDPH when it occurs is to prevent it when the dura is accidentally punctured during labor epidural placement. Multiple therapeutic strategies have been reported in the medical literature to prevent this outcome. Preventive measures range from conservative strategies to invasive procedures. Bedrest and hydration have been traditionally recommended to try to prevent PDPH when a wet tap occurs; however, no conclusive evidence supports their use. The use of oral and intravenous caffeine is insufficiently supported by clinical evidence. Epidural morphine and intravenous cosyntropin have been successfully used to prevent PDPH. Epidural injection of normal saline reduces the gradient for CSF leak. The use of saline has shown variable results in different studies. Although the results of some studies show insufficient evidence about its effectiveness, administration of epidural saline is a technique relatively devoid of significant adverse effects. The institutional protocol recommends the combination of a multimodal approach to prevention of PDPH after accidental dural puncture, based on strategies reported in the medical literature. The protocol consists of the immediate administration of 60 cc of epidural normal saline, followed by two preventive measures administered after delivery. After delivery, 1 mg of intravenous cosyntropin and 3 mg of epidural morphine before catheter removal are administered. This study tests the hypothesis that the multimodal prophylactic protocol described above decreases the incidence of PDPH and the need to perform epidural blood patch, compared to other strategies or no prophylactic management.

To investigate the role of KATP channels on the cerebral hemodynamic in migraine patients.

The study will be described the development and implementation of the Clinical pathway (CPW) for acupuncture treatment in the management of patients with some chronic pain conditions. The effectiveness of this CPW will be explored in this study through retrospective analysis of clinical outcomes after administration of acupuncture treatment summarised in the guidelines.

Background: Postdural puncture headache (PDPH), which is one of the complications of spinal anesthesia, is a condition that negatively affects the quality of life of patients, causes late mobilization and prolonged hospital stay. Sphenopalatine ganglion block (SGB) has created a minimally invasive, easy, and safe treatment alternative. Objective: Evaluating the effectiveness of topical SGB on PDPH treatment. Design: Retrospective observational study Setting: Single center tertiary level of care hospital study. The files of PDPH patients between Jan 2018 and Jan 2020 were scanned. Patients: PDPH patients aged 18-65 are included and any patients with primary/secondary headache history are excluded. Main outcome measures: Patients were divided into 2 groups. The group that given only conservative treatment was named as Group C, and the group of patients who had additionally been applied SGB was named as Group SGB. Headache severity was measured with Visual Analogue Scale (VAS) at the 1st,3rd, 12th and 24th hours of the treatment, in supine and upright position.

The proposed research will be a prospective, observational study to test the hypothesis that anchoring will affect verbal pain scores in the emergency department. There will be a small retrospective aspect to this study to obtain patient satisfaction ratings.
