Insights
Pertussis, or whooping cough, can present atypically in disabled children. A case study highlights that this bacterial infection may not cause typical coughing fits in these vulnerable patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Pertussis (whooping cough) is a highly contagious respiratory infection caused by Bordetella pertussis.
- Classic symptoms include severe coughing fits followed by a characteristic 'whooping' sound.
- Clinical presentation and disease course in disabled children remain poorly understood.
Observation:
- A case involving a disabled girl with a history of tracheostomy and laryngotracheal separation was observed.
- The patient presented with increased tracheal secretions and required hospitalization.
- Notably, the patient did not exhibit the hallmark cough associated with pertussis.
Findings:
- Sputum Gram stain revealed numerous short, gram-negative rods, suggestive of an unusual bacterial infection.
- A nucleic acid amplification test confirmed the presence of Bordetella pertussis.
- The patient demonstrated clinical improvement following treatment with azithromycin.
Implications:
- Pertussis can manifest atypically in disabled children, lacking classic symptoms like prolonged coughing.
- Healthcare providers should consider pertussis in disabled children with respiratory symptoms, even without a cough.
- Early diagnosis and treatment are crucial for managing pertussis in this population.
Abstract:
Pertussis is characterized by intense, prolonged coughing in children often followed by a distinctive whooping sound on inspiration. However, the clinical manifestations and natural course of pertussis in disabled children are largely unknown. We experienced a case of pertussis in a disabled girl who had previously undergone a tracheostomy and laryngotracheal separation. She presented with increased tracheal secretions and required hospitalization but did not develop a cough. Pertussis was suspected from the sputum Gram stain, which revealed numerous, short gram-negative rods that did not grow on chocolate agar. A nucleic acid amplification test was positive for Bordetella pertussis and the patient improved on azithromycin. Pertussis may present without its cardinal symptoms in disabled children.

Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
