※ 引述《chihuahua (chihuahua)》之铭言： <<原始文吃光光>> : 题目问:典型的表现 : Pertussis is an acute respiratory tract infection that was well described : initially in the 1500s. Sydenham first used the term pertussis, meaning : intense cough, in 1670; it is preferable to whooping cough because most : infected individuals do not “whoop.” : 但是 : Adenoviral infections are usually distinguishable by associated features, : such as fever, sore throat, and conjunctivitis. : [Mycoplasma causes protracted episodic coughing, but patients usually have : a history of fever, headache, and systemic symptoms at the onset of disease : as well as more continuous cough and frequent finding of rales on : auscultation of the chest.] : 资料来源:Nelson 18 edition : 这题可以说它没有清楚的etiology,所以如果是etiology是Mycoplasma infection的话, : 还是会 [frequent finding of rales on auscultation of the chest]? : 覆议的请推文 谢谢 Kliegman: Nelson Textbook of Pediatrics, 18th ed. Chapter 194 – Pertussis (Bordetella Pertussis and Bordetella Parapertussis) CLINICAL MANIFESTATIONS. Classically, pertussis is a prolonged disease, divided into catarrhal, paroxysmal, and convalescent stages. The catarrhal stage (1–2 wk) begins insidiously after an incubation period ranging from 3–12 days with nondistinctive symptoms of congestion and rhinorrhea variably accompanied by low-grade fever, sneezing, lacrimation, and conjunctival suffusion. As initial symptoms wane, coughing marks the onset of the paroxysmal stage (2–6 wk). The cough begins as a dry, intermittent, irritative hack and evolves into the inexorable paroxysms that are the hallmark of pertussis. A well-appearing, playful toddler with insignificant provocation suddenly expresses an anxious aura and may clutch a parent or comforting adult before beginning a machine-gun burst of uninterrupted coughs, chin and chest held forward, tongue protruding maximally, eyes bulging and watering, face purple, until coughing ceases and a loud whoop follows as inspired air traverses the still partially closed airway. Post-tussive emesis is common, and exhaustion is universal. The number and severity of paroxysms escalate over days to a week and remain at that plateau for days to weeks. At the peak of the paroxysmal stage, patients may have more than 1 episode hourly. As the paroxysmal stage fades into the convalescent stage (?2 wk), the number, severity, and duration of episodes diminish. 所以以典型症状来看的话，她的呼吸音应该不会是正常的 -- --
