Immunoglobulin Deficiency a Treatable Cause of Fatigue in Patients With Multiple Sclerosis (MS)?
The investigators hypothesize that hypogammaglobulinemia (defined as IgG serum concentration <7.0g/L) is a treatable cause of fatigue in people with MS: The primary objective is to prove the link between hypogammaglobulinemia and fatigue in patients with multiple sclerosis. The secondary objective is to show that fatigue is mediated via frequent …
The Voice as a Tool to Detect Recurrence of Laryngeal and Hypopharyngeal Cancer
The investigators will obtain three-monthly voice recordings and fiberendoscopic examinations of the larynx/hypopharynx for a minimal period of 6 months from all laryngeal/hypopharyngeal squamous cell carcinoma (LSCC/HPSCC) patients, who have successfully completed curative primary treatment, except those who underwent total laryngectomy. Furthermore, the investigators will ask the patients to fill …
Pre-stenotic Inflammation Following Endoscopic Balloon Dilatation in Crohn's Disease: A Prospective Study
As a consequence of chronic relapsing inflammation in Crohn's disease (CD), progressive bowel damage and scarring occurs in affected regions of intestine. This damage often leads to narrowing, or stricturing of the bowel lumen, and even complete bowel obstruction. Stricturing CD is thought to be a major contributor to penetrating …
A Study to Explore the Role of Gut Flora in COVID-19 Infection
This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, is shed in the stools of patients who are infected.
Evaluation, Treatment and Monitoring of Patients With a Known or Suspected Parasitic Infection
The purpose of this study is to evaluate, treat and follow patients with parasitic infections. People with a known or suspected parasitic infection who are at least 1 year old may be enrolled. This study does not involve any experimental treatments. Participants will have a physical examination and laboratory tests …
Optic Nerve Sheath Diameter, Carotid Duplex and Transcranial Duplex as a Prognostic Factor
Optic nerve sheath diameter (ONSD) had been proved to be associated with increased intracranial pressure and can be used as one of the prognostic factors in cardiac arrest patients. It is simple, quick and can be measured repeatedly. Carotid duplex and transcranial duplex(TCD) provide rapid, noninvasive, real-time measures of cerebrovascular …
Metabolic Control and Patient Well-being in Phenylketonuria: do Guidelines Make a Difference?
Treatment of PKU implies for most patients that with strict adherence to dietary treatment they can achieve excellent neurocognitive outcome. Dietary treatment, though, is hard to comply to every day and with every single meal. Unsurprisingly, health-related quality of life (HrQol) is negatively affected if patients have to follow a …
MR-BIO: A Study to Evaluate Changes in MR Imaging and Biological Parameters
The MR BIO study aims to understand the changes in the tumour and normal tissues during a course of radiotherapy. This is accomplished by studying the MR images taken during each treatment session on the MR Linear accelerator (MR Linac). The overarching hypothesis is that changes in MR imaging and …
Evaluation of Volume and Electrolyte Balance in Hyponatremia Treatment - a Prospective Observational Trial
To assess quantitatively the evolution over time of electrolyte-free water clearance and electrolyte mass balance in patients with non-hypervolemic hypotonic hyponatremia
SPL Insufficiency Syndrome (SPLIS)/NPHS14: a SPLIS Observational Study and Patient Registry (International)
This protocol aims to gather information about sphingosine phosphate lyase insufficiency syndrome (SPLIS), also known as NPHS14, and to create a SPLIS patient registry. Medical records, radiological and pathology results, blood test results, and genetic information will be collected. Samples of blood, cheek cells, urine and stool may be collected …
