Active clinical trials for "Croup"

The purpose of this study is to identify, from a societal perspective, the costs and associated benefits of three strategies for disseminating and implementing a practice guideline that addresses the management of croup.

Croup is common illness presenting emergency department with dyspnea. The main treatment for croup is nebulized L-epinephrine and steroid. The study for the dose of nebulized L-epinephrine is restricted that the study of comparision between racemic epinephrine and L-epinephrine. The investigators conducted this study to compare the effectiveness of low dose L-epinephrine with conventional dose L-epinephrine.

The investigator will issue a Patient Information Consent for the participant in the study. 1.Patients will be asked to complete the Reflux Symptom Index questionnaire. Clinical survey, medical history. 2. Objective methods for assessing the patient's condition: - examination of ENT organs. 3. Laboratory and instrumental research methods: Endoscopic laryngoscopy and video laryngoscopy, pH-metry, acoustic voice analysis. 4.Sociological method. 5. Subjective methods for assessing the condition of the larynx. 6. Аnalysis of the received data

Saliva plays an important role in the homeostasis of the digestive tract mucosa. Salivary organic components, such as the Epidermal Growth Factor(EGF) have been found in defficient concentrations in patients with gastroesophageal reflux disease (GERD) and reflux related laryngitis (LPR). The epidermal growth factor receptor (EGFR) signaling pathway is one of the most important pathways that regulate growth, survival, proliferation, and differentiation in mammalian cells Eperdermal growth factor receptor (EGFR) overexpression has been linked to hyperproliferative diseases. It is unknown if the inflammatory process in GERD is realated to difficiencies in EGFR expression. The objective of the current study was to try to establish a correlation between the expression of EGFR in the laryngeal and esophageal mucosa and the severity of laryngitis in adults with GERD and LPR

In this observational study insights regarding the tolerability and influence on the quality of life of the topical treatment Ectoin Mund- and Rachenspray compared to Emser Pastillen in patients with acute Pharyngitis/ Laryngitis under real life conditions shall be gained. Patients are treated with Ectoin Mund- & Rachenspray 1% or Emser Pastillen according to the demands of the physician and the instructions for use.

The purpose of this research study is to better understand whether information obtained from a pH probe can help physicians predict whether a patient will respond to the medication that is prescribed for laryngopharyngeal reflux (LPR). The current treatment given to individuals who are diagnosed with LPR is a course of proton pump inhibitor (PPI) medication. Subjects who agree to participate in this study will have a small flexible tube (about the width of a piece of cooked spaghetti) placed in their throat. This tube measures the pH in the throat over a period of 24 hours and helps physicians study the relationship between pH level, LPR symptoms, and the effectiveness of PPI therapy. This study may help physicians find out if certain symptoms or characteristics can help them predict if the PPI medication will be effective for each patient. After probe removal, subjects will receive compensation. They will return to the clinic at their regularly scheduled follow-up visit with the physician, 8 to 12 weeks after starting the PPI medication. At that time, subjects can choose to participate in an optional probe placement.

Saliva plays a key role in the homeostasis of the digestive tract The reflux of gastroesophageal contents may cause damage to the esophageal, laryngeal and pharyngeal mucosas There seems to be no correlation between the severity of reflux episodes and the intensity of inflammatory changes, suggesting individual protective mechanisms to refluxate exposure Inorganic and Organic Salivary changes have been associated to Gastroesophageal Reflux Disease (GERD) and its supraesophageal manifestations, especially reflux laryngitis (Laryngopharyngeal Reflux- LPR) Decreased salivary Epidermal Growth factor (EGF) concentrations have been found in patients with GERD and LPR, but it is unclear if these are primary or secondary to the disease. Hypothesis: The decreased salivary EGF concentrations in patients with reflux laryngitis is primary and therefore would not change after treatment and control of the disease

Pediatrician does physical examination through telemedicine and in real life to see whether the telemedicine consultation corresponds with the real life examination. Goal is to determine: Check practical feasability Check whether there are no great objections for a larger study (ie. in case telemedicine consultation is much more unreliable to do a physical examination a larger study is deemed unsafe)
