- Incidence of spontaneous pneumothorax during or within 24 hours following air travel [ Time Frame: 3 years ]The investigators will measure the number of pneumothoraces that occur either during air travel, or within 24 hours of air travel among patients with Birt-Hogg-Dube syndrome. The incidence of air travel related pneumothorax will be calculated by dividing the number of pneumothoraces to the total number of flights undertaken by the entire cohort.
- Rate of recurrent pneumothorax in patients with Birt-Hogg-Dube syndrome [ Time Frame: 3 years ]The investigators will catalogue the number roof spontaneous pneumothoraces experienced by patients with Birt-Hogg-Dube syndrome. These results will be used to calculate the proportion of patients who experience at least one recurrence of their pneumothorax, as well as the average number of pneumothoraces experienced per patient.
- Efficacy of pleurodesis in reducing the risk of recurrent pneumothoraces in Birt-Hogg-Dube syndrome [ Time Frame: 3 years ]The investigators will measure the incidence of ipsilateral pneumothorax following pleurodesis in order to determine the efficacy (as measured by the rate of pneumothorax recurrence following pleurodesis). These results will be calculated separately for chemical and surgical pleurodesis.
