OBJECTIVE: In this study, we evaluated the clinical characteristics and seasonal distribution of patients with primary spontaneous pneumothorax

and examined the relationships between meteorological factors and pneumothorax development overall and in terms of first episode and recurrence.

METHODS: The hospital records of 168 pneumothorax patients treated in our clinic between January 2016 and December 2020 were reviewed

retrospectively. A cluster was defined as two or more patients with pneumothorax presenting within three consecutive days. Meteorological factors

were compared between days with and without pneumothorax patients. This comparison was based on meteorological data from the day of

symptom onset (D), the day before symptom onset (D1), and the difference between those days (D–D1). Meteorological data from the index day

(D) were also compared between patients with first episode and recurrence of pneumothorax.

RESULTS: The study included 149 (88.7%) men and 19 (11.3%) women. The mean age was 25.02Å}6.97 (range, 17–35; median, 26) years.

Of note, 73 (43.4%) patients underwent surgery. The highest number of patients presented in November (n=19, 11.3%). In terms of season, most

presentations occurred in autumn. Humidity was significantly lower on recurrence days compared with first episode (p=0.041).

CONCLUSION: Our results indicated that meteorological factors (i.e., atmospheric pressure, humidity, wind speed, temperature, and precipitation)

were not associated with pneumothorax development. By comparing the patients with first episode and recurrence, the humidity was significantly

lower in the recurrence group.
