Adult croup

Uncommon presentation of a common disease: influenza A presenting as adult croup

An 88-year-old woman presented to our emergency room with complaints of fever, coryza, barking cough and generalised fatigue for 2 days. Physical examination showed stridor, tachypnoea with use of accessory muscles of respiration on admission. Laboratory tests were unremarkable except for monocytosis with a normal total white cell count. Rapid influenza diagnostic test was positive for influenza A. Chest X-ray showed subglottic narrowing of the trachea suggestive of steeple sign. A diagnosis of influenza A-induced croup was made. She was given humidified oxygen, nebulised racemic epinephrine, intravenous dexamethasone and oseltamivir. Stridor resolved within minutes of giving nebulised epinephrine. Work of breathing improved within 4-6 hours. She was discharged 2 days later on a tapering dose of steroids.

Prognostic factors and importance of recognition of adult croup

OBJECTIVES

Croup, or laryngotracheobronchitis, is a common disease in childhood. On the other hand, to our knowledge, there are only 14 cases in six English literatures describing adult croup (AC). The clinical features of AC have not been well known.

METHODS

We conducted a retrospective analysis of medical records of 18 patients with AC during the period from 2008 to 2016.

RESULTS

None of the 18 patients required an urgent airway intervention. Univariate analysis indicated that the duration of symptoms was significantly longer in patients with cough (p < .01) and younger patients (age < 60, p = .037). The duration of subglottic edema was significantly longer in female (p = .035), patients with high levels of CRP (≥1 mg/dL, p = .049), and patients with cough symptom (p = .035).

CONCLUSIONS

Female, young age (<60 years), the symptom of cough, and high levels of CRP should be recognized as signs of prolonged AC. It is important to confirm the diagnosis of AC by laryngoscopic examination, which also help to avoid airway intervention.

Update on childhood and adult infectious tracheitis

The trachea is a pivotal organ of the respiratory tract. Rather than a genuine anatomic border, it acts as a crossroad in all respiratory infectious processes. Even though not strictly limited to the trachea, infections such as laryngotracheitis and tracheobronchitis are frequently diagnosed in children, in particular during the winter season. Infectious tracheitis etiologies are diverse and the distinction between viral and bacterial origins, albeit difficult, remains relevant considering the substantial differences in terms of gravity and therapeutic management. This literature review summarizes the microbiological and clinical aspects of community-acquired and nosocomial tracheitis in adults and children, as well as the adequate diagnostic and therapeutic approaches. It also highlights the emergence of fungal tracheitis in immunocompromised patients, of ventilator-associated tracheitis in intensive care medicine, and beyond all that the potential short and long-term consequences of tracheitis.

Clinical characteristics of children and adolescents with croup and epiglottitis who visited 146 Emergency Departments in Korea

Purpose

Croup is a common pediatric respiratory illness with symptoms of varying severity. Moreover, epiglottitis is a rare disease that can rapidly progress to life-threatening airway obstruction. Although the clinical course and treatments differ between croup and epiglottitis, they are difficult to differentiate on presentation. We aimed to compare the clinical characteristics of croup and epiglottitis in Emergency Department patients.

Methods

The 2012 National Emergency Department Information System database of 146 Korean Emergency Departments was used to investigate patients aged ≤18 years presenting with croup or epiglottitis.

Results

We analyzed 19,374 croup patients and 236 epiglottitis patients. The male:female sex ratios were 1.9:1 and 2.3:1 and mean ages were 2.2±2.0 and 5.6±5.8 years, respectively. The peak incidence of croup was observed in July and that of epiglottitis was observed in May. The hospitalization rate was lower in croup than in epiglottitis patients, and the proportion of patients treated in the intensive care unit was lower among croup patients. The 3 most common chief complaints in both croup and epiglottitis patients were cough, fever, and dyspnea. Epiglottitis patients experienced dyspnea, sore throat, and vomiting more often than croup patients (P<0.05).

Conclusion

Both groups had similar sex ratios, arrival times, 3 most common chief complaints, and 5 most common comorbidities. Epiglottitis patients had a lower incidence rate, higher mean age of onset, and higher hospitalization rate and experienced dyspnea, sore throat, and vomiting more often than croup patients. Our results may help in the differential diagnosis of croup and epiglottitis.

Croup

Most children who present with acute onset of barky cough, stridor, and chest-wall indrawing have croup. A careful history and physical examination is the best method to confirm the diagnosis and to rule out potentially serious alternative disorders such as bacterial tracheitis and other rare causes of upper-airway obstruction. Epinephrine delivered via a nebuliser is effective for temporary relief of symptoms of airway obstruction. Corticosteroids are the mainstay of treatment, and benefit is seen in children with all levels of severity of croup, including mild cases.

Croup in the paediatric emergency department

Croup is a common childhood illness. The majority of children presenting with an acute onset of barky cough, stridor and indrawing have croup. A careful history and physical examination is necessary to confirm the diagnosis of croup, and to rule out potentially serious alternative causes of upper airway obstruction. Nebulized adrenaline is effective for the temporary relief of airway obstruction. Corticosteroids are the mainstay of treatment in children with croup of all levels of severity.

Croup, a disorder of the anal phase of development. A contribution to our understanding of the psychosexual development of the larynx

A brief history of croup is presented. The forms of croup under examination are defined with emotional factors at one end of a continuum and viral and traumatic factors at the other. The complexity of the disorder and its peculiar clinical characteristics are explained. Some of these characteristics are: (1) the predominant 1-3-year age range, which corresponds to the anal stage of development; (2) the relief afforded by vomiting; (3) the occurrence of attacks at night and during sleep, (4) the relative dryness of the cough and its harsh metallic quality; (5) the frequent presence of a ticklish, irritating sensation in the throat; and (6) the presence of edema and/or laryngospasm. Three case vignettes are presented. These cases support a previously developed theory concerning the impulses and defenses underlying the croup attack. Croup is seen as a fixation at the oral level with a regression to that level in the face of conflicts of the anal or sometimes the oedipal stage. The psychosexual development of the larynx is discussed.
