Although a minority of asthma patients suffer from severe asthma, they represent a major clinical challenge in terms of poor symptom control despite high-dose treatment, risk of exacerbations, and side effects. Novel biological treatments may benefit patients with severe asthma, but are expensive, and are only effective in appropriately targeted patients. In some patients, symptoms are driven by other factors than asthma, and all patients with suspected severe asthma (‘difficult asthma’) should undergo systematic assessment, in order to differentiate between true severe asthma, and ‘difficult-to-treat’ patients, in whom poor control is related to factors such as poor adherence or co-morbidities. The Nordic Consensus Statement on severe asthma was developed by the Nordic Severe Asthma Network, consisting of members from Norway, Sweden, Finland, Denmark, Iceland and Estonia, including representatives from the respective national respiratory scientific societies with the aim to provide an overview and recommendations regarding the diagnosis, systematic assessment and management of severe asthma. Furthermore, the Consensus Statement proposes recommendations for the organization of severe asthma management in primary, secondary, and tertiary care.

“…In our patients, the inspiratory loop of the flow-volume curve was truncated or showed flattening as demonstrated in Figure 2a and b [9]. We did not employ provocation testing to confirm abnormal vocal cords closure such as by using aerosolized methacholine, administering inhaled mannitol powder, performing strenuous exercise on a treadmill or bicycle ergometer, breathing in refrigerated cold air, or inhaling odorants/irritants, such as perfume or cleaning agents containing chlorine or ammonia [10,11]. Impulse oscillometry was not employed in any case [12].…”

“…Causes of VCD: The true prevalence of VCD is somewhere in the neighborhood of 3 in 100 persons, falling between 2.5% and 2.8% [10]. Currently, the exact etiology of VCD following an inhalation exposure (or even VCD itself) remains unknown.…”

Vocal Cord Dysfunction after an Inhalation Exposure

The manuscript embodies case material and the author's extensive personal experience to address a perceived or actual airborne exposure when incorrectly judged as due to intrathoracic/lung damage when in reality the outcome is the more innocuous extrathoracic/upper airway's vocal cord dysfunction (VCD). Because of the conviction of possible lung injury, the individual applies the fetal protective glottic closure reflex to counteract an odorant cue instigating acute VCD. Breathing against an obstructed glottis as well as hyperventilation from anxiety, panic and/or fear of personal harm worsens the laryngeal spasm. Spirometer shows flattening of the inspiratory loop of the flow-volume curve and endoscopy, while not done, would reveal adduction of the anterior two-thirds of the vocal cords with posterior chinking creating a diamond shape configuration. Successful therapy and management of VCD requires a speech therapy approach rather than physician prescribed medications.

Vokal kord disfonksiyonu, laringeal wheezing ya da laringeal astım olarak da bilinen bozukluk, vokal kordların inspiryum süresince paradoksal olarak kapanıp, obstrüktif hava yolu semptomlarına yol açması ile karakterizedir. Mekanizma tam olarak bilinmemekle birlikte psikojenik faktörlerin ön planda sorumlu olduğu düşünülmektedir. Hastalığın şiddeti hafif dispneden entübasyon ya da trakeostomi gerektiren solunum yetmezliğine kadar değişir. Wheezing, stridor ve nefes darlığı tipik bulgulardandır. Hastalığın tanısı semptomatik dönemde yapılan laringoskopi ile vokal kordların paradoksal hareketinin gözlenmesi ile konulur. Bu olgu sunumunda, acil servise entübasyon gerektiren akut solunum yetmezliği ile başvuran, takiplerinde 3 kez daha entübe edilen, daha sonra vokal kord disfonksiyonu tanısı konularak lazer kordotomi ile tedavi edilen 70 yaşında bayan hasta tartışılmaktadır. Anahtar Sözcükler: Vokal kord disfonksiyonu, solunum yetmezliği, tekrarlayan entübasyon.Vocal cord dysfunction, also known as laryngeal wheezing or laryngeal asthma, is a disorder characterized by paradoxical closure of the vocal cords intermittently during inspiration and causing obstructive airway symptoms. The mechanism is unclear, but is thought to be responsible for psychogenic factors in the foreground. Severity of the disease varies from mild dyspnea to respiratory failure with requiring intubation or tracheostomy. Wheezing, stridor and dyspnea are the typical symptoms. Diagnosis is made by observation of paradoxical vocal cords movement by laryngoscopy, during symptoms. In this case report, a 70 year old female patient was discussed, who presented with acute respiratory failure with requiring intubation in the emergency room, and in the days that followed was intubated 3 more times. At the end the diagnosis was vocal cord dysfunction and treated with laser cordotomy.
