===Overview===
==Overview==
 
[[Tracheitis]] means [[inflammation]] of the [[trachea]]. It presents with [[cough]], [[fever]] and sore throat. Sudden deterioration can occur within few days due to superimposed [[bacterial]] [[infection]]. High fever, [[tachypnea]], [[stridor]] and [[hoarseness]] develop. Differential diagnosis include viral [[croup]], [[epiglottitis]], [[pharyngitis]], [[retropharyngeal]] [[abscess]], [[diptheria]], angioneurotic [[edema]] and [[subglottic]] [[stenosis]]. The table below explains the differentiation in detail.
===Differentiating tracheitis from other diseases===
Bacteria tracheitis must be differentiated from other causes of throat pain as shown below:


==Differentiating tracheitis from other diseases==

Overview

Tracheitis means inflammation of the trachea. It presents with cough, fever and sore throat. Sudden deterioration can occur within few days due to superimposed bacterial infection. High fever, tachypnea, stridor and hoarseness develop. Differential diagnosis include viral croup, epiglottitis, pharyngitis, retropharyngeal abscess, diptheria, angioneurotic edema and subglottic stenosis. The table below explains the differentiation in detail.

Differentiating tracheitis from other diseases

Bacteria tracheitis must be differentiated from other causes of airway disease such as croup, epiglottitis, pharyngitis, tonsillitis, retropharyngeal abscess and subglottic stenosis.

Variable Croup Epiglottitis Pharyngitis Bacterial tracheitis Tonsilitis Retropharyngeal abscess Subglottic stenosis
Presentation Cough Sore throat, pain on swallowing, fever, headache, abdominal pain, nausea and vomiting Barking cough, stridor,

fever, chest pain,

ear pain, difficulty breathing, headache, dizziness.

Sore throat, pain on swallowing, fever, headache, cough

Neck pain, stiff neck, torticollis

fever, malaise, stridor, and barking cough

Depends on severity. May have respiratory distress at birth, exercise-induced dyspnea, intermittent wheezing. Inspiratory stridor. [1]
Stridor
Drooling
Others are Hoarseness, Difficulty breathing, symptoms of the common cold, Runny nose, Fever Other symptoms include difficulty breathing, fever, chills, difficulty swallowing, hoarseness of voice
Causes Parainfluenza virus H. influenza type b, beta-hemolytic streptococci, Staphylococcus aureus, fungi and viruses. Group A beta-hemolytic streptococcus. Staphylococcus aureus Most common cause is viral including adenovirus, rhinovirus, influenza, coronavirus, and respiratory syncytial virus. Second most common causes are bacterial; Group A streptococcal bacteria,[2]  Polymicrobial infection. Mostly; Streptococcus pyogenes, Staphylococcus aureus and respiratory anaerobes (example; Fusobacteria, Prevotella, and Veillonella species)[3][4][5][6][7][8] Congenital, trauma
Physical exams findings Suprasternal and intercostal indrawing,[9] Inspiratory stridor[10], expiratory wheezing,[10] Sternal wall retractions[11] Cyanosis, Cervical lymphadenopathy, Inflammed epiglottis Inflammed pharynx with or without exudate Subglottic narrowing with purulent secretions in the trachea[12][13] Fever, especially 100°F or higher.[14][15]Erythema, edema and Exudate of the tonsils.[16] cervical lymphadenopathy, Dysphonia.[17] Child may be unable to open the mouth widely. May have enlarged

cervical lymph nodes and neck mass.

Signs of respiratory distress, intermittent wheezing. Inspiratory stridor. [1]
Age Mainly 6 months and 3 years old

rarely, adolescents and adults[18]

Used to be mostly found in

pediatric age group between 3 to 5 years,

however, recent trend favors adults

as most commonly affected individuals[19]

with a mean age of 44.94 years.

Mostly in children and young adults,

with 50% of cases identified

between the ages of 5 to 24 years.[20]

Mostly the first six years of life

Children between 5 and 15 years old[21]

Mostly between 2-4 years, but can occur in other age groups.[22][23] May be congenital congenital or acquired. Mean age in acquired is 54.1 years[24]
Imaging finding Steeple sign on neck X-ray Thumbprint sign on neck x-ray Lateral neck xray shows intraluminal membranes and tracheal wall irregularity. Intraoral or transcutaneous USG may show an abscess making CT scan unnecessary.[25][26][27] CT scan:
  • a mass impinging on the posterior pharyngeal wall with rim enhancement is seen[28][29]
Bronchoscopy reveals subglottic stenosis. Computed tomography may reveal a concentric stenotic tracheal segment.[30]
Treatment Dexamethasone and nebulised epinephrine Airway maintenance, parenteral Cefotaxime or Ceftriaxone in combination with Vancomycin. Adjuvant therapy includes corticosteroids and racemic Epinephrine.[31][32] Antimicrobial therapy mainly penicillin-based and analgesics. Airway maintenance and antibiotics Antimicrobial therapy mainly penicillin-based and analgesics with tonsilectomy in selected cases. Immediate surgical drainage and antimicrobial therapy. emperic therapy involves; ampicillin-sulbactam or clindamycin. Endoscopic balloon dilation for patients with low-grade subglottic stenosis,[33] glucocorticoid injections, and resection.[34]
