Background: Gastroesophageal reflux disease (GERD) is a common disease that is often diagnosed based on typical symptoms of heartburn and regurgitation. In addition to these more classic manifestations, GERD is increasingly associated with extra-esophageal symptoms, including chronic cough, asthma, laryngitis, and aspiration pneumonia. Management of GERD may help in management of these respiratory diseases. Aim of Study:To study the presence of chest diseases in non-smoker patients complaining of GERD. Subjects and Methods:The study was carried out on 100 patients attended to Al-Hussein and Sayed Galal Al-Azhar University Hospitals in the period from September 2017 to May 2018. Patients were categorized into two groups: Group 1: Included 100 patients complaining of heartburn, epigastric pain and respiratory symptoms confirmed to have GERD by upper GI endoscope. Group 2: Include fifty patients apparently healthy (as regard GERD symptoms) confirmed that they were not have GERD by upper GI endoscope. All patients underwent history taking, examination, routine lab investigations, upper GI endoscopy, chest X-ray and spirometry. C.T. chest was done on need according to symptoms and chest Xray finding.Results: Respiratory disorders occurrence was more in GERD group than in negative group as regard GERD with statistically significant difference between the two groups in chronic laryngitis, bronchial asthma, COPD, and pneumonia, but no significant difference between the two groups wos found as regard ILD. Conclusion:GERD is a considrable risk factor for the development of respiratory disorders. This study proved that pulmonary symptoms was elevated among those with frequent GERD compared to those without GERD.

This study was carried out to evaluate the pre and post hatching performance of Fayoumi chicks produced from eggs exposed to high incubation temperature and sprayed with L-Carnitine. A total number of 600 eggs were used and randomly distributed into four groups, each group consisted of three replicates of 50 eggs. The first group served as control without any treatment (C), the second (T1) was exposed to high incubation temperature (40 o ) for 3 hours daily, the 3 rd and 4 th groups (T2 and T3, respectively) were exposed to high temperature (40 o ) for 3 hours at 6 th , 7 th and 8 th of incubation period, and sprayed with L-Carnitine at levels 25 and 50ml /Liter, respectively. Hatchability traits, live body weight (LBW), body weight gain (BWG), feed consumption (FC), feed conversion ratio (FCR) and carcass traits of chicks hatched in all treated group were studied during the period from 0 to 12 weeks of age. Results revealed that LBW, BWG, FC and FCR were significantly (P<0.05) improved in T2 and T3 groups. Chicks in T2 group had the higher (P<0.05) relative weights of liver, gizzard and spleen. From these results, it could be concluded that spraying of L-carnitine at level 25 ml/L after exposure to high incubation temperature (40 o ) during the 6 th , 7 th and 8 th days of incubation for three hours daily from 12 pm to 3 pm markedly improved chick performance post hatching compared with other groups.
