Pulmonary arterial hypertension (PAH) is characterized by enhanced proliferation of pulmonary artery smooth muscle cells and endothelial cells associated with obliteration of small pulmonary arterioles and formation of plexiform lesions. To date, no curative treatments have been identified for pulmonary arterial hypertension. There are various therapeutic options, including conventional medical therapies and oral, subcutaneous, intravenous, and inhalation delivery. We have previously shown that miR-143/145 knockout can prevent the development of chronic hypoxia-induced pulmonary hypertension (PH) in mice...

BACKGROUND: Animal studies suggest that neural plasticity may play a role in the antidepressant effects of a single ketamine dose. However, the potential effects of repeated ketamine treatments on human neuroplasticity are unknown. METHODS: This pilot RCT study measured plasticity-induced changes before and after a ketamine course, in three treatment-resistant depressed subjects, who were randomized to receive 8 intranasal treatments of 100mg ketamine or 4.5mg midazolam...

BACKGROUND: Allergic rhinitis (AR) is a common condition that can be treated with a number of different therapies. Treatments such as intranasal antihistamines (INAs) and intranasal steroids (INSs) are widely used by AR patients. For some allergy sufferers, a combination of therapies, specifically an INA and an INS, is required to address their symptoms. A new treatment, the formulation of azelastine hydrochloride and fluticasone pro-pionate used as a single spray (MP-AzeFlu), has become available for AR patients who need both types of treatment...

The authors discuss the mechanism of action, effectiveness, and safety of intranasal glucocorticosteroids (inGCS) used to treat acute, recurrent and chronic rhinosinusitis (RS). The last version of the European guidelines concerning the application of inGCS assigns the highest level of evidence-Ia and the highest strength of recommendations-A to these medications when applied for the treatment of acute and polypoid rhinosinusitis. Moreover, they acquire the status of the agents of choice for the therapy of chronic RS without polyps...

BACKGROUND: Analgesia administration for children with vaso-occlusive crises is often delayed in the emergency department. Intranasal fentanyl (INF) has been shown to be safe and effective in providing rapid analgesia for other painful conditions. Our objective was to determine if children with a vaso-occlusive crisis (VOC) who received initial treatment with INF compared to placebo achieved a greater decrease in pain score after 20 min. PROCEDURE: This was a randomized, double-blind, placebo-controlled trial...

: Bdellovibrio bacteriovorus and Micavibrio aeruginosavorus are predatory bacteria that naturally-and obligately-prey on other Gram-negative bacteria, and their use has been proposed as a potential new approach to control microbial infection. The ability of predatory bacteria to prey on Gram-negative human pathogens in vitro is well documented; however, the in vivo safety and efficacy of predatory bacteria have yet to be fully assessed. In this study, we examined whether predatory bacteria can reduce bacterial burden in the lungs in an in vivo mammalian system...

BACKGROUND: Vasoconstrictors and local anesthetics are commonly administered using a squeeze bottle atomizer to the nasal mucosa to reduce edema, limit bleeding, and provide analgesia. Despite widespread use, there are few clinical guidelines that address technical details related to safe administration. The purpose of this study was to quantify, via simulation, the amount of liquid delivered to the nasal mucosa when patients are in the supine and upright positions and administration parameters that would reliably provide the desired amount of medication per spray...

Screening for obstructive sleep apnea (OSA) with in-laboratory polysomnography is recommended for children with sleep disordered breathing. Adenotonsillectomy is the first-line therapy for pediatric OSA, although intranasal steroids and montelukast can be considered for those with mild OSA and continuous positive airway pressure for those with moderate to severe OSA awaiting surgery, poor surgical candidates or persistent OSA. Bony or soft tissue upper airway surgery is reasonable for children failing medical management or those with persistent OSA following adenotonsillectomy...

BACKGROUND: Allergic rhinitis (AR) is the most common chronic disease among children. To characterize the disease, a modified classification of severity (m-ARIA) has recently been validated in AR children. When medical treatment fails, surgery for nasal obstructive disorders (NOD) may be a therapeutic option. Our objective was to assess the prevalence of NOD and their influence in medical treatment response among children with persistent AR (PER). METHODS: In a prospective, real-life study, 130 pediatric PER patients (13...

PURPOSE: Our objective was to highlight the importance of database selection in observational research and to determine the incidence of corticosteroid-related events in patients exposed to fluticasone propionate intranasal spray (FPNS) compared with other intranasal steroids (INS). METHODS: After a feasibility study using an electronic medical record database in the UK (1990-2002), a retrospective cohort study was conducted using a large administrative claims database in the USA from 1994 to 2002 comparing the incidence and rate ratios of steroid-related events among intermittent, sub-chronic, and chronic FPNS use and other INS use episodes...

OBJECTIVE: Intranasal (IN) midazolam is a commonly prescribed medication for pediatric sedation and anxiolysis. One of its most frequently-encountered adverse effects is discomfort with administration. While it has been proposed that premedicating with lidocaine reduces this undesirable consequence, this combination has not been thoroughly researched. The objective of our study was to assess whether topical lidocaine lessens the discomfort associated with IN midazolam administration. METHODS: This was a double-blinded, randomized, placebo-controlled trial performed in an urban, academic pediatric emergency department...

Hydrocodone bitartrate extended-release (Hysingla(®) ER; referred to hereafter as hydrocodone ER) was the first single-entity hydrocodone formulation recognized by the US FDA as having abuse-deterrent properties. It is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Once-daily oral hydrocodone ER provides consistent plasma hydrocodone concentrations and sustained analgesia over the 24-h dosing interval...

Allergic rhinitis is a common nasal disorder with a high impact on quality of life, high social costs in therapies, and a natural development towards asthma. Pharmacological therapy is based on several genres of medications, of which intranasal corticosteroids are currently the most widespread. Thermal water treatment has traditionally been used as adjunctive treatment for chronic rhinitis and sinusitis. The present study was carried out to assess the clinical efficacy of nasal inhalation of radioactive oligomineral water vapours from the Merano hot spring and to compare it with the clinical efficacy of mometasone furoate nasal spray...

Metal nanoparticles have been proposed as a carrier and a therapeutic agent in biomedical field because of their unique physiochemical properties. Due to these physicochemical properties, they can be used in different fields of biomedicine. In relation to this, plasmonic nanoparticles can be used for detection and photothermal destruction of tumor cells or toxic protein aggregates, and magnetic iron nanoparticles can be used for imaging and for hyperthermia of tumor cells. In addition, both therapy and imaging can be combined in one nanoparticle system, in a process called theranostics...

REVIEW
Alexei Gonzalez-Estrada, Stephen A Geraci
Allergic diseases are common in women of childbearing age. Both asthma and atopic conditions may worsen, improve or remain the same during pregnancy. Primary care physicians commonly encounter women receiving multiple medications for pre-existing atopic conditions, who then become pregnant and require medication changes to avoid potential fetal injury or congenital malformations. Each medication should be evaluated; intranasal and inhaled steroids are relatively safe to continue during pregnancy (budesonide is the drug of choice), second-generation antihistamines of choice are cetirizine and loratadine, leukotriene receptor antagonists are safe, sparing use of oral decongestants during the first trimester and omalizumab may be used for both uncontrolled asthma and for antihistamine-resistant urticaria...

There is an emerging interest to develop human vaccines against medically-important fungal pathogens and a need for a preclinical animal model to assess vaccine efficacies and protective correlates. HLA-DR4 (DRB1∗0401 allele) transgenic mice express a human major histocompatibility complex class II (MHC II) receptor in such a way that CD4(+) T-cell response is solely restricted by this human molecule. In this study HLA-DR4 transgenic mice were immunized with a live-attenuated vaccine (ΔT) and challenged by the intranasal route with 50-70 Coccidioides posadasii spores, a potentially lethal dose...

OBJECTIVE/BACKGROUND: Intranasal sumatriptan (Imitrex(®) ) may be an alternative for patients who refuse injections and cannot tolerate oral agents, but due to low bioavailability and slow absorption, the clinical utility of the currently marketed formulation is limited, highlighting an unmet need for an effective non-oral migraine medication with a rapid onset of action. To overcome the slow absorption profile associated with intranasal administration, we evaluated the impact of 1-O-n-Dodecyl-β-D-Maltopyranoside (DDM, Intravail A-3™), a permeation enhancer, on sumatriptan's pharmacokinetic profile by comparing the pharmacokinetic characteristics of two commercial sumatriptan products, 4 mg subcutaneous and 6 mg subcutaneous in healthy adults, with DFN-02 - a novel intranasal agent comprised of sumatriptan 10 mg plus 0...

INTRODUCTION: Fentanyl is the most widely studied intranasal (IN) analgesic in children. IN subdissociative (INSD) ketamine may offer a safe and efficacious alternative to IN fentanyl and may decrease overall opioid use during the emergency department (ED) stay. This study examines the feasibility of a larger, multicentre clinical trial comparing the safety and efficacy of INSD ketamine to IN fentanyl and the potential role for INSD ketamine in reducing total opioid medication usage. METHODS AND ANALYSIS: This double-blind, randomised controlled, pilot trial will compare INSD ketamine (1 mg/kg) to IN fentanyl (1...

Currently, evidence supports the use of intranasal midazolam as an effective, and in many cases, preferable treatment option for prolonged seizures in children. Despite this knowledge, intranasal midazolam is not routinely found as a standard of care. The goal of this project was to implement the use of intranasal midazolam as a rescue medication for prolonged seizures within a child neurology practice and, in doing so, create a model for implementation that would be replicable for other practice sites. This project focused on the development of a process to make intranasal midazolam available as a treatment option and then the creation of an educational intervention for providers within a child neurology practice...
