Achieving symptom relief in patients with myalgic encephalomyelitis by targeting the neuro-immune interface and optimizing disease tolerance.

Myalgic encephalomyelitis (ME) previously also known as chronic fatigue syndrome is a heterogeneous, debilitating syndrome of unknown etiology responsible for long-lasting disability in millions of patients worldwide. The most well-known symptom of ME is post-exertional malaise, but many patients also experience autonomic dysregulation, cranial nerve dysfunction and signs of immune system activation. Many patients also report a sudden onset of disease following an infection.

Resting-state fMRI study of acute migraine treatment with kinetic oscillation stimulation in nasal cavity.

Kinetic oscillatory stimulation (KOS) in the nasal cavity is a non-invasive cranial nerve stimulation method with promising efficacy for acute migraine and other inflammatory disorders. For a better understanding of the underlying neurophysiological mechanisms of KOS treatment, we conducted a resting-state functional magnetic resonance imaging (fMRI) study of 10 acute migraine patients and 10 normal control subjects during KOS treatment in a 3 T clinical MRI scanner. The fMRI data were first processed using a group independent component analysis (ICA) method and then further analyzed with a voxel-wise 3-way ANOVA modeling and region of interest (ROI) of functional connectivity metrics.

Kinetic oscillation stimulation as treatment of acute migraine: a randomized, controlled pilot study.

Objective: To assess the relief of migraine pain, especially in the acute phase, by comparing active treatment, ie, kinetic oscillation stimulation (KOS) in the nasal cavity, with placebo.

Background: Exploratory trials testing the efficacy of KOS on migraine patients indicated that this treatment could be a fast-acting remedy for acute migraine pain.

Method: Thirty-six patients were randomized 1:1 using a placebo module to active or placebo treatment in this double-blinded parallel design study.

Kinetic oscillation stimulation as treatment of non-allergic rhinitis: an RCT study.

Conclusion: Kinetic oscillation stimulation (KOS) of nasal mucosa at low frequency seems to be a possibly effective and safe short-term treatment of non-allergic nasal stuffiness.

Objective: To assess the relief of rhinitis symptoms, especially stuffiness, by comparing active treatment, i.e.

Non-malignant respiratory tract fistula from the oesophagus. A lethal condition for which novel therapeutic options are emerging.

Objectives: Fistulas between the oesophagus and the respiratory tract can occur as a complication to anastomotic dehiscence after oesophageal resection, without any signs of local residual tumour growth. Other causes that are, by definition, benign may rarely prevail. The traditional therapeutic approach is to divert the proximal portion of the oesophagus and transpose the conduit into the abdominal cavity.

Tracheobronchial transplantation with a stem-cell-seeded bioartificial nanocomposite: a proof-of-concept study.

Background: Tracheal tumours can be surgically resected but most are an inoperable size at the time of diagnosis; therefore, new therapeutic options are needed. We report the clinical transplantation of the tracheobronchial airway with a stem-cell-seeded bioartificial nanocomposite.

Methods: A 36-year-old male patient, previously treated with debulking surgery and radiation therapy, presented with recurrent primary cancer of the distal trachea and main bronchi.

The role of pain-mediating sensory nerves in histamine-induced inflammation of nasal mucosa.

Topical application of histamine on the nasal mucosa causes an inflammatory reaction with increased mucosal swelling and perfusion. In the nasal mucosa histamine receptors are found in the vascular epithelium and at free sensory nerve endings. The aim of this randomized double-blind placebo controlled study was to investigate if this inflammatory reaction to locally administered histamine was dependent upon the stimuli of pain-mediating sensory nerves, or if it mainly was the result of direct stimuli of the vascular epithelium.

Swine dust exposure is a model for rapid induction of non-allergic neutrophil inflammation in the nasal mucosa of healthy volunteers, and the symptoms as well as the microcirculation are modified by nasal lavage.

Background: The pathophysiological mechanism of non-allergic rhinitis is not clear and there is a lack of models in healthy volunteers. It has previously been shown that swine dust exposure is an excellent method for inducing inflammatory changes in the lower airways. We have shown earlier that exposure to swine dust increases the histamine sensitivity of the nasal mucosa as measured by rhinostereometry.

Upper-airway inflammation in relation to dust spiked with aldehydes or glucan.

Objectives: Organic dust is associated with adverse effects on human airways. This study was done to investigate whether the addition of beta-(1,3)-D glucan or aldehydes to office dust causes enhanced inflammation in human airways.

Methods: Thirty-six volunteers were exposed randomly to clean air, office dust, dust spiked with glucan, and dust spiked with aldehydes.

Nasal mucosal histamine reactivity among teachers six years after working in a moisture-damaged school.

Objectives: The objective of this study was to determine whether verified increased nasal mucosal reactivity among teachers, who had been working in a school with severe moisture problems, still persisted 6 years after remedial measures had been taken. The increased nasal mucosal reactivity, measured as the mucosal swelling reaction upon histamine provocation, had earlier been shown both 1 and 3 years after the renovation.

Methods: Twenty-four teachers in the target school and sixteen teachers in the control school, who participated in all the investigations (1995, 1997 and 2000), answered a standardized questionnaire and underwent a nasal histamine provocation test.

Nasal and bronchial histamine responsiveness in pollen-exposed patients with seasonal rhinitis.

In a previous study, we found an increased nasal responsiveness as measured by rhinostereometry and histamine challenge out of season in a sample of 12 patients suffering mainly from hay fever. The aim of the present study was to investigate whether airway responsiveness in these patients was further increased after direct pollen exposure, after a single nasal pollen provocation as well as by repeated exposure during the pollen season. In spite of increased allergic symptoms, the basal degree of nasal mucosal swelling was unchanged before histamine challenge under these circumstances.
