Assessment of Central Sensitization, Neuropathic Pain, Sleep Quality and Daily Life Activities in...
Behcet's DiseaseCentral SensitisationThere are few studies in the literature regarding increased frequency of neuropathic pain and sleep disturbance and decreased quality of life in Behçet's disease. Frequency of central sensitization was not investigated in patients with Behçet's disease before. In this study, it is aimed to investigate the frequency of central sensitization, neuropathic pain, sleep disorder and quality of life and their relation to each other in Behcet's disease.
Neuropathic Pain After Breast Surgery
Chronic Neuropathic PainPostoperative5 moreTo understand pain pathophysiology in terms of risk factors and protective mechanisms ranging from molecular pathways to societal impacts.
DOLORisk: Research on Risk Factors and Determinants for Neuropathic Pain
Neuropathic PainPatients with neuropathic pain of multiple etiologies and a control cohort of patients with the same neuropathic entities who did not develop neuropathic pain are examined clinically, phenotyped with QST and questionnaires. Both groups are analyzed in order to find risk factors for painful neuropathy.
Genetic, Neurophysiological and Psychological Risk Factors for Neuropathic Pain
SurgeryThe objective of these cohorts is to detect potential genetic, neurophysiological psychological and cognitive risk factors for the development of chronic postsurgical pain including neuropathic pain.
Study to Estimate the Burden of Herpes Zoster and Postherpetic Neuralgia in Spain
Herpes ZosterThe purpose of this study is to collect data on the incidence, complications and impact on quality of life of herpes zoster (HZ) disease in adults >=50 years of age in Spain. This study will also collect data on costs related to the HZ disease, especially postherpetic neuralgia (PHN)
A Study to Assess the Burden of Herpes Zoster and Postherpetic Neuralgia in Japanese Adults Aged...
Herpes ZosterThe study aims to estimate the incidence of herpes zoster (HZ), proportion of postherpetic neuralgia (PHN) and the economic burden and impact on quality of life, in Japanese adults greater than or equal to sixty years of age.
Persistent Pain After Breast Cancer Treatment With Docetaxel
Breast NeoplasmsPain3 moreBreast cancer treatment is for many patients followed by sequelae, such as persistent pain, sensory disturbances, lymphedema and reduced physical function. These undesired consequences of the treatment are a major clinical problem, with persistent pain affecting 25-60%, sensory disturbances 20-80%, lymphedema 2-86% and reduced physical function 13-28% of patients. Development of persistent pain after breast cancer treatment, involves a complex pathophysiology that involves pre-, intra- and postoperative factors. Several risk factors for the development of persistent pain after breast cancer treatment have been identified; young age, psychosocial factors, surgical procedure and radiation therapy. Neurotoxicity is a well know attribute of many chemotherapeutic agents, such as taxanes. The purpose of this nationwide study is to retrospectively examine a cohort of breast cancer patients treated with docetaxel, to clarify if docetaxel may influence the prevalence and intensity of persistent pain and other sequelae.
Neurophysiological Characterization of Postherniotomy Pain
Postoperative PainPostherniotomy Pain1 moreSensory function is different in persistent postherniotomy pain patients than in operated controls, suggesting this to be a neuropathic pain syndrome. By performing quantitative sensory testing, the specific changes in pain patients will be revealed, thereby aiding in designing future treatment trials. MRI scans of the groin regions in pain patients and control patients will be evaluated by senior MRI specialists assessing potential pathology to the region (Mesh, inflammation, edema, funicle etc.) Assessors will be blinded to clinical status, and surgery.
Evolution of Pain From Herpes Zoster
Post-Herpetic NeuralgiaAcute Herpes ZosterEvolution of pain and neural injury will be evaluated at 2 years or longer after the onset of AHZ by multiple measures. Assessments at 2 years or longer will be compared to those collected during the first 6 months after HZ in order to test whether or not sensory function and cutaneous innervation continues to normalize beyond 6 months in subjects who recover from HZ without severe PHN.
Validation Study of Neuropathic Pain
Neuropathic Pain From Spinal Cord InjuryDiabetic Peripheral Neuropathy1 moreThis study seeks to validate clinically evoked or obtained objective pain signs with the patient's corresponding quantified subjective pain symptoms. This will allow for validation of objective clinical pain signs to then be used to begin to classify patients with pain based on symptoms and signs. This then can be used as a basis for further study of neuropathic pain mechanisms in human patients.
