Overview

Historical Perspective

  • The word Cough was first derived from the middle English Coughen or old English Cohhian which was primarily composed of the middle Dutch Kochen and the high middle German Kuchen, in early 14th century.

Classification

  • Cough in children may be classified or defined according to the duration of presenting complaints, quality and sound, causes of cough into several groups.[1]:
  • 1 Duration of Presenting complaints: According to the duration of cough, it can be sub classified into three categories.
    • Acute: Cough persists for less than three weeks.
    • Subacute: Cough persists for three to eight weeks.
    • Chronic: Cough persists for more than eight weeks.
  • 2. Quality and sounds: According to the quality and sound cough can be sub classified in to following categories-
    • Dry or Hacking or Nonproductive.
    • Wet or productive cough.
    • Staccato or short repetitive cough.
    • Whooping or paroxysmal violent or spasmodic cough.
    • Barking cough: Brassy barking or Honking barking.
    • Phlegmy cough.
    • Burning cough.
  • 3. Causes of Cough: Based on causes cough is subdivided into following three sub groups-
    • Normal or expected cough.
    • Specific cough.
    • Non-specific cough.
  • 4. Anatomic classification on causes of cough: Cough can be produced from different anatomical locations. for example-
    • Nose and Paranasal sinuses.
    • Pharynx.
    • Larynx.
    • Trachea and Bronchi.
    • Pulmonary parenchyma.
    • Pleura.
    • Mediastinum.
    • Heart and blood vessels.
    • External ear and Tympanic membrane.
    • Esophagus.
  • 5. Grades of cough: Cough can be graded into four main sub categories-[2]
    • Eutussia or Normal.
    • Hypertussia or Sensitized.
    • Hypotussia or Desensitized.
    • Dystussia or Pathological.
    • Atussia or Absent.

Cough in children can also be classified under infectious (Bacterial, Viral, fungal, Parasitic) or non-infectous categories broadly.

Pathophysiology

  • Cough is natural innate primitive reflex that helps in mucocilliary clearance of foreign particles and secretions from respiratory tracts. It is also a defensive mechanism protecting respiratory airways from aspiration of pathogens, particulates and secretions. A complex arc comprised of neuro-respiratory pathways helps in initiating the cough reflex.[3]
 
 
 
Mechanical and chemical stimulation of cough receptors (Rapidly adapting receptors, slowly adapting receptors or C-fibers) in Respiratory airways
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Afferent pathways: Sensory nerve fibers via Vagus Nerve from ciliated columnar epithelium of upper airways, cardiac and esophageal branches from diaphragm send impulse to central cough center
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Central cough center in upper brain stem medulla and pons send impulse of sequence of phases (Inspiratory, Compressive, Expiratory) for constituting cough
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Efferent pathways: The nucleus retroambigualis sends impulse via phrenic and spinal motor nerves to diaphragm and abdominal and respiratory muscles, the nucleus ambiguous sends impulse to larynx by laryngeal branches of vagus nerve
 
 
 
  • On gross pathology, Bloody, Serous , Mucoid, Rusty, Pink frothy, and Purulent are characteristic findings of sputum produced by coughing.
  • On microscopic histopathological analysis, Pathogens, RBCs, Leukocytes, epithelial celss are characteristic findings of Sputum produced by coughing.
