Abstract
Introduction: Spontaneous pneumothorax is believed to result from blebs, or from other abnormalities of the pleural surface. Weather conditions may precipitate spontaneous pneumothorax. Aim: Investigate the influence of weather conditions on the onset of primary spontaneous pneumothorax. Methods: The case histories of 200 patients with spontaneous pneumothorax treated in Sousse between January 2010 and December 2014 were analyzed. It is a retrospective descriptive epidemiological study of two time series (meteorological data, pneumothorax cases).Data on weather conditions were collected daily throughout the 5-year period. Results: The mean age was 28±17.11 years. The number of smoker patients was 162.In 2010, the largest number of pneumothorax cases was recorded (26.5%). A risk of occurrence of pneumothorax was significant during the summer season. A comparison of the mean temperature between days with and without pneumothorax showed significantly higher temperatures during the days of pneumothorax. A decrease of 1% in the relative humidity in D-1 was associated with an increase in the risk of pneumothorax by 1.6% (p=0,02). The occurrence of clusters was associated with higher temperature averages on the same days, one day before and two days before with p=0.038, p=0.008 and p=0.006respectively. This same observation was made regarding the average duration of sunshine two days before the cluster onset (p = 0.05). The occurrence of storms two days before the occurrence of clusters was also significantly associated with a risk multiplied by 1.96. Conclusion: There was a correlation between Clusters of spontaneous pneumothorax and weather conditions.
