In otorhinolaryngology, the diagnosis of pharyngo-laryngeal or rhinosinusal inflammatory conditions secondary to GER is one of exclusion and it is based on a detailed anamnesis in which we are interested in symptoms, behavioural and medical risk factors, on the ENT clinical examination, the laryngo-fibroscop- ical assessment, the phoniatric examination, the barite pharyngo-esogastric exam, the upper gastrointestinal endoscopy and the esophageal manometry. The authors are making a systematization of the contribution of the gastroesophageal reflux has in the ENT pathology, em- phasising the sympytoms and the most frequent associated pathological entities.

Hipersensibilitate la substanțele active sau la oricare dintre excipienți(lactoza monohidrat). Atenţionări şi precauţii speciale pentru utilizare. Seretide Diskus nu se utilizează pentru tratamentul crizelor de astm bronşic, în acest caz fi ind necesară administrara unui bronhodilatator cu acțiune rapidă şi de scurtă the documentation being made by the esophageal pH durată. Pacienții trebuie sfătuiți să păstreze tot timpul asupra lor un inhalator necesar pentru tratamentul crizei. Tratamentul cu Seretide Diskus nu trebuie inițiat în timpul unei exacerbări sau dacă pacienții prezintă o agravare 6 semnifi cativă sau o deteriorare acută a astmului bronşic. În timpul tratamentului cu Seretide Diskus pot să apară reacții adverse grave legate de astmul bronşic şi exacerbarea acestuia. Pacienții trebuie sfătuiți să continue test . tratamentul, dar să ceară sfatul medicului dacă nu se mai realizează controlul astmului bronşic sau simptomele se agravează după inițierea tratamentului cu Seretide Diskus. Tratamentul cu Seretide Diskus nu trebuie întrerupt brusc la pacienții cu astm bronşic, datorită riscului de exacerbare a afecțiunii. Dozele trebuie scăzute treptat sub supravegherea medicului. La pacienții cu BPOC, oprirea tratamentului se poate asocia cu decompensări THE INCIDENCE OF THE GASTROESOPHA- simptomatice şi de aceea trebuie făcută sub supravegherea medicului. GEAL REFLUX DISEASE Similar altor corticosteroizi inhalatori, Seretide Diskus trebuie administrat cu precauție în cazul pacienților cu tuberculoză pulmonară activă sau pasivă, infecții fungice, virale sau altfel de infecții ale căilor respiratorii. Seretide Diskus trebuie utilizat cu precauție la pacienții cu tulburări cardiovasculare severe sau aritmii cardiace şi la pacienți cu diabet zaharat, tireotoxicoză, hipokaliemie netratată sau pacienți predispuşi a avea concentrații scăzute de CLINICAL FEATURES OF THE GASTRO- potasiu în sânge. A fost raportată o incidență crescută a infecțiilor de tract respirator inferior (în special pneumonii şi bronşite) în studiul TORC. Doza de corticosteroid inhalată trebuie redusă la cea mai mică doză cu care se menține un control efi cient asupra astmului.
