CSF Leak Following Microvascular Decompression: the Benefit of Routine Postoperative Lumbar Tap...

Cranial Nerve DiseasesFacial Neuralgia2 more

Even at centers with very large experience, the risk of cerebrospinal fluid (CSF) leakage in surgery for microvascular decompression is reported up to 3%. Prevention of leakage is important since meningitis may follow. Also, leakage usually means longer hospital stay and increased cost. In case of detected leakage extra sutures may be applied, placement of a lumbar drain may be considered or a revision and improved closure may be attempted. With leakage in the subcutaneous tissue, but not through the skin, a local accumulation causing local symptoms may also occur. In addition to being burdensome and being associated with longer hospital stays with possible revision surgery, such complications are also very costly. The best way to reduce cost and burden, and to improve patient care, is to prevent CSF leakage. The aim of this study is to determine if prophylactic lumbar tap is beneficial for prevention of cerebrospinal fluid leakage following microvascular decompression, by comparison of surgical approaches in 3 geographical areas in the Scandinavian health system. Hypothesis: There is no difference in cerebrospinal fluid leakage between the group subject to prophylactic spinal tap versus the group without prophylactic spinal tap.

Transcriptome Sequencing Analysis of Whole Blood From Patients With Trigeminal Neuralgia

Trigeminal NeuralgiaBlood2 more

Trigeminal neuralgia is a type of neuropathic pain that brings great physical and psychological pressure to patients. Chronic pain can cause changes in the composition of central and peripheral body fluids, and these changes may be useful for the prediction and treatment of pain. In this study, the whole blood of patients with trigeminal neuralgia and non-chronic pain was collected, and transcriptome sequencing (RNA-seq) was performed to determine the peripheral transcriptome changes of trigeminal neuralgia (TN) patients. And compare the expression of neuropeptide Y (NPY) in plasma and cerebrospinal fluid of TN and non-chronic pain patients.

Translation of the Self Completed-Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale...

Neuropathic PainChronic Pain1 more

Neuropathic pain, described as 'pain arising as a direct consequence of a lesion or disease on the somatosensory system', affects up to 3-9.8% of the investigators' population, but is often underdiagnosed and undertreated. As treatment is different for patients with neuropathic pain and nociceptive pain, it is important to screen for neuropathic pain. Commonly employed questionnaire-based diagnostic tools in English speaking countries include the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (LANSS) and Neuropathic pain questionnaire (NPQ). Self-completed LANSS is particularly useful as it is not restricted to clinician's examination and can be applied in large-scale research. S-LANSS has been successfully translated, validated and used successfully in Arabic and Turkish, but it has not been utilised in the Chinese population. As verbal translations of the English questionnaires used at the bedside may be prone to errors in interpretation and requires medical practitioners to interpret the questions. Therefore a translation and validation study is essential.

Pain In Neuropathy Study

Diabetic NeuropathyNeuropathic Pain3 more

In the context of peripheral neuropathy, we will aim to elucidate correlates between sensory symptoms and: Sensory nerve dysfunction. Cutaneous small nerve fibre innervation density. Psychological co-morbidity. Circadian rhythm disturbance co-morbidity. Functionality and Quality of life. Patterns of human brain activity in a subset of patients that consent to participate in the FMRI (functional magnetic resonance imaging) component of PINS. 2. We will also collect blood samples in this phenotyped cohort of patients. These blood samples coupled with detailed phenotype data will investigate potential gene associations only in the development of painful neuropathy. 3. Knowledge gained from the study will be used to aid the further development of pain questionnaires, designed to detect patients with painful neuropathy. 4.Knowledge gained from the study will be invaluable in informing on-going investigations of painful peripheral neuropathy in animal models, both in our laboratory and others.

Post-Operative Pain After Recovery in Thoracic Surgery

Neuropathic PainPost Operative Pain1 more

Persistent pain after surgery has significant physical and mental consequences for the patient, as well as a significant economic impact on health systems. Neuropathic pain is caused by direct or indirect damage to the somatosensitive system. In thoracic surgery, chronic neuropathic pain is represented by Post-Thoracotomic Pain Syndrome (PTPS), defined as recurrent or persistent pain in the thoracotomy scar site that persists for more than 3-6 months. Currently, in literature, the prevalence of PTPS is extremely variable. This prospective observational study aims to assess the incidence of pain in the weeks and months following surgery and to assess whether and how the presence of painful symptoms changes the patient's quality of life.

Molecular Mediators of Nerve Injury Signaling

DiabetesNerve Injury1 more

Specific proteins and other signaling molecules are increased and decreased following nerve injury. Some of these are important in producing pain or explaining why pain persists after traumatic nerve injuries or in disease states such as diabetes. In this study, the investigators hypothesize that it is possible to detect changes in specific signaling molecules and that these will provide insights into novel treatment strategies. The patients to be included are those who are undergoing the removal of tissue during surgery. The tissues that would otherwise be discarded will be included in the study as appropriate.
