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.
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.
The study included 149 (88.7%) men and 19 (11.3%) women. The mean age was 25.02±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).
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.
本研究评估了原发性自发性气胸患者的临床特征和季节分布，并考察了气象因素与气胸整体发展以及首发和复发的关系。
回顾性分析了 2016 年 1 月至 2020 年 12 月在我院就诊的 168 例气胸患者的病历。将连续 3 天内出现 2 例或 2 例以上气胸患者定义为一个集群。比较了有和无气胸患者的气象因素。这种比较是基于症状出现日（D）、症状出现前 1 日（D1）和这两天之间的差异（D-D1）的气象数据。还比较了气胸首发和复发患者的索引日（D）的气象数据。
本研究纳入了 149 例（88.7%）男性和 19 例（11.3%）女性患者。平均年龄为 25.02±6.97 岁（范围：17-35 岁；中位数：26 岁）。值得注意的是，73 例（43.4%）患者接受了手术。就诊人数最多的月份是 11 月（n=19，11.3%）。就季节而言，大多数气胸发生在秋季。复发日的湿度明显低于首发（p=0.041）。
我们的结果表明，气象因素（即大气压、湿度、风速、温度和降水量）与气胸的发展无关。通过比较首发和复发患者，复发组的湿度明显较低。
