DENT3060 Lecture Notes - Lecture 27: Cerebral Venous Sinus Thrombosis, Pulsus Paradoxus, Bronchial Hyperresponsiveness
Document Summary
Cold, sinusitis, laryngitis, flu, bronchitis, copd, asthma, pneumonia, tb, osa, bronchial carcinoma. Common symptoms: cough, chest pain, haemoptysis, breathlessness, wheezing. (esp. acute) due to bacterial infection, often follows upper respiratory tract viral infection. Signs/symptoms: pain/tenderness over involved sinuses, headache, mild fever. Investigation: diagnosis usu. clinical; x-ray may reveal sinus mucosal thickening or fluid level. Management: atb, nasal vasoconstrictors, analgesics/antipyretics: untreated chronic sinusitis, meningitis, venous sinus thrombosis. Chronic slowly progressive respiratory disorder characterised by airflow obstruction, results in irreversible lung function impairment in most cases: pathological changes in large airways (chronic bronchitis), small airways (bronchiolitis), lung parenchyma (emphysema) Cause/predisposing factors: smoking, coal dust exposure, low bw, poor ses: pt subclinical lung disease, acute episode of infections may precipitate respiratory failure. Signs/symptoms: hyperinflated lungs, flattened diaphragm (cid:858)blue bloaters(cid:859): productive cough, breathlessness, cyanosis, peripheral oedema, coarse precipitations, cor-pulmonale, respiratory failure, polycythemia (cid:858)pink puffers(cid:859): breathless/tachypnoea (rapid breath), chest hyperinflation,
