NCT ID: NCT01976039 Completed - Nasal Obstruction Clinical Trials

Rhinopharyngeal Retrograde Clearance is Effective to Adequate Upper Airways Function in Adults

Start date: July 2012
Phase: N/A
Study type: Interventional

Professionals working in polluted areas may present increased clinical airways symptoms and dysfunction. Rhinopharyngeal retrograde clearance (RRC) has been used to improve mucus clearance in infants with bronchitis and bronchiolitis, and instillation the nasal cavity with saline has been used to reduce nasal inflammation in rhinitis and sinusopathies. The aim of this study was to assess the effects of RRC and RCC combined with saline (RRC+S) on nasal mucociliary clearance (MCC), mucus surface property, cellularity and airways symptoms in professional motorcyclists.

NCT ID: NCT01965457 Completed - Clinical trials for Obstructive Sleep Apnea

Assessment of Adenoidal Obstruction in Children : Clinical Signs Versus Flexible Nasal Endoscopy and Roentgenographic Findings

Start date: September 2013
Phase: N/A
Study type: Observational

The term adenoids describes lymphoid tissue on the superior and posterior walls of the nasopharynx, and their hypertrophy is a common condition of childhood. When enlarged, adenoids can obstruct the nasopharyngeal airway and cause mouth-breathing, hyponasal voice, and snoring. In more severe cases, obstructive sleep apnea (OSA) may result, which carries potential risk of neurocognitive disturbance, growth failure, and heart-lungs disease. Adenoid hypertrophy can also be associated with otitis media with effusion, possibly through Eustachian tube dysfunction or chronic adenoidal infection. Methods for identification of adenoid hypertrophy include the clinical history, examination, imaging (eg, plain lateral x-ray), or by nasal endoscopy witch enable direct visualization of the nasal cavity with dynamic evaluation of any nasal airway obstruction. Objectives : The aim of this study is to prospectively examine invasive and non-invasive office procedures to assess adenoids hypertrophy, including clinical history, x-ray imaging, and nasal endoscopy. Methods : Prospective, observational study in pediatric patients aged 2-18 that will be referred to the otolaryngology pediatric 'Clalit' clinic in Haifa after x-ray imaging and an informed consent. 1. Nasal Obstruction Index (NOI) The NOI questionnaire for history and physical exam will be evaluated at the clinic, as described by Paradise grading system. 2. Plain lateral x-rays Plain lateral X-rays of the patients will be evaluated only if the patients had them at the time of referral. Adenoidal obstruction will be assessed by Fujioka's Adenoid-Nasopharynx ratio. 3. Fiberoptic nasal endoscopy (FNE) Fiberoptic analysis will be done as an office procedure using a 2.4mm Storz nasal flexible endoscope following an application of Lidocaine gel locally into the nostril and on the endoscope distal end. Adenoidal obstruction will be assessed by Parikh grading system.

NCT ID: NCT01907243 Completed - Nasal Obstruction Clinical Trials

The Role of Spreader Flaps in Preventing of Nasal Obstruction

Start date: May 2011
Phase: Phase 3
Study type: Interventional

Nasal obstruction is a preventable complication of rhinoplasty, for which the spreader graft is the gold standard. More recently, the spreader flap technique has been espoused as an alternative to spreader grafting. Herein we evaluated the efficacy of this technique in a randomized trial setting.

NCT ID: NCT01850511 Completed - Nasal Obstruction Clinical Trials

The Effect of Nasal Hair on Nasal Obstruction

Start date: May 2013
Phase: N/A
Study type: Interventional

Nasal obstruction is a common complaint prompting presentation to an otolaryngologist. Many studies have been performed quantifying and describing the impact of a number of factors on symptoms of nasal obstruction, including anatomical, neoplastic, infectious, and inflammatory causes. Despite this scrutiny, no attention has been paid to the nasal vibrissae as a potential anatomical contributor to nasal obstruction. The proposed study intends to elucidate that contribution, if any exists.

NCT ID: NCT01847131 Completed - Clinical trials for Nasal Obstruction Present Finding

Effectiveness of Oxymetazoline Added on Nasal Steroid in Rhinitis With Persistent Nasal Obstruction

Start date: April 2013
Phase: Phase 4
Study type: Interventional

Background Allergic rhinitis is a common health problem with a worldwide prevalence is 10-25%, and poses significant impact on the quality of life of the patients. In Thailand, the prevalence of allergic rhinitis in the general population is 13.5%, of which the frequency of allergic rhinitis increased from 23% to 38% in the children, and 61.9% in the graduate students. Despite intranasal steroid being the current first-line treatment of patients with allergic rhinitis, only 60% of patients achieve excellent control. Persistent nasal congestion is the major symptom which is difficult to control in these patients. Data are limited about efficacy and safety of the additional use of 0.05% intranasal oxymetazoline hydrochloride (OXY) for persistent nasal congestion that does not adequately respond to recommended doses of intranasal steroid (INS) and oral antihistamine(OAH). Objective To determine the efficacy and safety of the additional use of OXY for persistent nasal congestion in allergic rhinitis or non-allergic rhinitis patients inadequately controlled by combination treatment with INS and OAH. Methods The investigators performed a 6-week, randomized, double blind, placebo controlled, clinical trial in 50 patients with allergic rhinitis or non-allergic rhinitis whom inadequately controlled by combination treatment with INS and oral antihistamine (OAH). After an initial screening, qualified individuals were randomized into 2 groups including the treatment group and the control group. The treatment group received the INS (2 puffs in each nostril twice daily) and OAH (1 tablet once daily) plus OXY (2 puffs in each nostril twice daily) The control group received INS (2 puffs in each nostril twice daily) and OAH (1 tablet once daily) plus placebo (2 puffs in each nostril twice daily).

NCT ID: NCT01695967 Completed - Sleep Apnea Clinical Trials

Turbinate Cauterization in Pediatric Patients With Nasal Obstruction

Start date: August 2012
Phase: N/A
Study type: Interventional

patients will be placed in 2 groups, with or without turbinate cautery ( a surgical method to reduce the size of the skin covered bones in the nose), at the time of adenoidectomy and tonsillectomy. It will compare the amount of nasal congestion for each group with the idea that it will be less if treated with turbinate cauterization. Assessments from baseline to 6 months post procedure will be compared between the two groups.

NCT ID: NCT01541839 Completed - Nasal Obstruction Clinical Trials

Comparison of a Septal Stapler to Suture Closure in Nasal Septoplasty

Start date: February 2012
Phase: N/A
Study type: Interventional

The primary objective of this study is to determine if there is a time savings in the operating room by using a septal stapler instead of suture in closure of primary septoplasty. The secondary objectives are to determine the subjective outcome of patients undergoing closure with the septal stapler instead of suture via questionnaire, and to determine if there is a difference in postoperative complications between groups.

NCT ID: NCT01506583 Completed - Fatigue Clinical Trials

Clinical Evaluation of QFlu Combo Test

QFlu
Start date: November 1, 2010
Phase:
Study type: Observational

Currently effective antivials for influenza treatment are two influenza viral neuraminidase inhibitors, oseltamivir (Tamiflu) and zanamivir (Relenza). Resistance to these drugs is reflected by reduced susceptibility of viral neuraminidase to these drugs. The hypothesis is that the signal ratio of two reagents (with or without a single concentration of the drug) correlates the IC50 value, an accurate measurement of drug resistance but impractical for clinical use.
