INTRODUCTION: Gastro-oesophageal reflux disease (GORD) has been implicated in the development of chronic rhinosinusitis (CRS). The association of GORD with CRS is systematically assessed from the medical literature. METHODOLOGY: Embase and MEDLINE were searched using a comprehensive strategy limited to English language and Human subjects. Any study with original data on the experimental, diagnostic, treatment or prognostic association of CRS with GORD was included...

To address the need for vaccine platforms that induce robust cell-mediated immunity, we investigated the potential of utilizing self-assembling biologic nanolipoprotein particles (NLPs) as an antigen and adjuvant delivery system to induce antigen-specific murine T cell responses. We utilized OT-I and OT-II TCR-transgenic mice to investigate the effects of NLP-mediated delivery of the model antigen ovalbumin (OVA) on T cell activation. Delivery of OVA with the TLR4 agonist monophosphoryl lipid A (MPLA) in the context of NLPs significantly enhanced the activation of both CD4(+) and CD8(+) T cells in vitro compared to co-administration of free OVA and MPLA...

Congenital dacryocystocele is a malformation of the nasolacrimal system. Most of the cases can be successfully treated with conservative treatment options such as sac massage. Congenital dacryocystoceles with concomitant intranasal cysts causing respiratory distress in the newborns are rarely published. In this case report we presented a 2-week-old newborn with bilateral congenital dacryocystoceles causing intermittent respiratory distress. We discuss the importance of nasal endoscopic treatment and multidisciplinary approach for these rare malformations in the light of the current literature...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a severe psychiatric disease accompanied by neuroendocrine changes such as adrenergic overdrive and hence an elevated cardiovascular morbidity. Current pharmacotherapeutic options for PTSD are less than suboptimal, necessitating the development of PTSD-specific drugs. Although the neuropeptide oxytocin has been repeatedly suggested to be effective in PTSD treatment, there are, to our knowledge, only three studies that have assessed its efficacy on the intensity of PTSD symptoms in PTSD patients - among them one symptom provocation study in male veterans...

BACKGROUND: Asthma is a common chronic lung disease characterized by airflow obstruction, airway hyperresponsiveness (AHR) and inflammation. IGFs have been reported to play a role in asthma but little is known about how the Insulin-like Growth Factor 1 Receptor (IGF1R) affects asthma pathobiology. METHODS: Female Igf1r-deficient and control mice were intranasally challenged with house dust mite (HDM) extract or PBS five days per week for four weeks. Lung function measurements, and bronchioalveolar lavage fluid (BALF), serum and lungs were collected on day 28 for further cellular, histological and molecular analysis...

OBJECTIVE: Morbidity and mortality associated with opioid use have increased across the nation, growing into what can only be described as an epidemic. SETTING: In Washington State between 2002 and 2004, the statewide death rate attributed to any opioid was 6.6 per 100,000 people, but between 2011 and 2013 it increased to 8.6 per 100,000 people. Pharmacies provide a unique access point for harm reduction services to patients due to their ease of accessibility in the community...

BACKGROUND: Helminth parasites have been reported to have beneficial immune modulatory effects in allergic and autoimmune conditions and detrimental consequences in tuberculosis and some viral infections. Their role in co-infection with respiratory viruses is not clear. OBJECTIVE: Here, we investigated the effects of strictly enteric helminth infection with Heligmosomoides polygyrus on respiratory syncytial virus (RSV) infection in a mouse model. METHODS: A murine helminth/ RSV co-infection model was developed...

BACKGROUND AND PURPOSE: Hyperglycaemia increases glucose concentrations in airway surface liquid (ASL) and increases the risk of pulmonary Pseudomonas aeruginosa infection. We determined whether reduction of blood and airway glucose concentrations by the anti-diabetic drug dapagliflozin could reduce P. aeruginosa growth/survival in the lungs of diabetic mice. EXPERIMENTAL APPROACH: The effect of dapagliflozin on blood and airway glucose concentration, the inflammatory response and infection were investigated in C57BL/6 J (wild type, WT) or db/db (leptin receptor-deficient) mice, treated orally with dapagliflozin prior to intranasal dosing with lipopolysaccharide (LPS) or inoculation with P...

OBJECTIVE: Excessive airway inflammation is seen in chronic obstructive pulmonary disease (COPD) patients experiencing acute exacerbations, which are often associated with human rhinovirus (HRV) infection. Alpha-1 antitrypsin (A1AT) has anti-inflammatory function in endothelial cells and monocytes, but its anti-inflammatory effect has not been investigated in COPD airway epithelial cells. We determined A1AT's anti-inflammatory function in COPD airway epithelial cells and the underlying mechanisms such as the role of caspase-1...

Unlike systemic infections, little is known about the role of repeated localized infections on (re)shaping pathogen-specific memory CD8 T cell responses. Here, we used primary (1°) and secondary (2°) intranasal influenza virus infections of mice as a model to study intrinsic memory CD8 T cell properties. We show that secondary antigen exposure, relative to a single infection, generates memory CD8 T cell responses of superior magnitude in multiple tissue compartments including blood, spleen, draining lymph nodes, and lung...

INTRODUCTION: Procedural sedation and analgesia (PSA) are frequently used for fracture reduction in pediatric emergency departments (ED). Combining intranasal (IN) fentanyl with inhalation of nitrous oxide (N2O) allow for short recovery time and obviates painful and time-consuming IV access insertions. METHODS: We performed a bicentric, prospective, observational cohort study. Patients aged 4-18years were included if they received combined PSA with IN fentanyl and N2O for the reduction of mildly/moderately displaced fracture or of dislocation...

A novel independent Th-cell subset, characterized by high expression of interleukin (IL)-9, has been recognized as the "Th9" subset. Although Th9 cells are important in many diseases, their contribution to allergic rhinitis (AR) remains unclear. We therefore first determined whether Th9 cells were present in a mouse model of AR. We then investigated the their involvement in the distribution of CD4+ T-cell subsets and the symptoms of AR by treating mice with anti-IL-9 antibodies (Abs). Anti-IL-9 Abs were administered intranasally during rechallenge of ovalbumin (OVA)-induced AR in BALB/c mice...

Experiments using female mice and bats have demonstrated that tritium-labeled 17β-estradiol ((3)H-E2) can be absorbed via cutaneous and intranasal routes and distributed to reproductive and neural tissues. Radioactivity has also been measured in tissues of untreated females after 48 h cohabitation with (3)H-E2 injected males. The present study was designed to quantify steroid transfer among female bats. Radioactive quantification via liquid scintillation counting revealed absorption of tritium-labeled progesterone ((3)H-P4) in adult females 1 h after cutaneous and intranasal application (10 μCi)...

Intranasal infection with vaccine strain of Venezuelan equine encephalitis virus (TC83) caused persistent viral infection in the brains of mice without functional αβ T-cells (αβ-TCR -/-). Remarkably, viral kinetics, host response gene transcripts and symptomatic disease are similar between αβ-TCR -/- and wild-type C57BL/6 (WT) mice during acute phase of infection [0-13 days post-infection (dpi)]. While WT mice clear infectious virus in the brain by 13 dpi, αβ-TCR -/- maintain infectious virus in the brain to 92 dpi...

Mycobacterium avium subsp. hominissuis (Mah) represents a health concern for humans and to a lesser extent for pigs, but its zoonotic potential remains elusive. Using multispacer sequence typing (MST) we previously identified 49 different genotypes of Mah among Belgian clinical and porcine isolates, with 5 MSTs shared by both hosts. Using experimental intranasal infection of BALB/c mice, we compared the virulence and immunogenicity of porcine and clinical human isolates with shared genotype or with a genotype only found in humans or pigs...

BACKGROUND: Many children with Trisomy 21 have neurologic or behavioral problems that make it difficult for them to remain still during noninvasive imaging studies, such as transthoracic echocardiograms (TTEcho). Recently, intranasal dexmedetomidine sedation has been introduced for this purpose. However, dexmedetomidine has been associated with bradycardia. Children with Trisomy 21 have been reported to have a higher risk of bradycardia and airway obstruction with sedation or anesthesia compared to children without Trisomy 21...

Intranasal spray application facilitates insulin delivery to the human brain. Although brain insulin modulates peripheral metabolism, the mechanisms involved remain elusive.Twenty-one men underwent two hyperinsulinemic-euglycemic clamps with D-[6,6-(2)H2]-glucose infusion to measure endogenous glucose production and glucose disappearance. On two days, participants received intranasal insulin or placebo. Insulin spillover into circulation after intranasal insulin application was mimicked by an iv insulin bolus on placebo day...
