“…However, we obtained results similar to some other trials that have reported no relationship between SP incidence and seasons, months [7]. SP occurs in episodes and clusters [11,12]. More than 2 cases in 3 consecutive days are considered a cluster of cases [7,12].…”

“…A sudden change in pressure may cause SP during flight or diving. Many former studies have investigated the impact of meteorological variables (atmospheric pressure, ambient temperature, amount of precipitation, humidity rate, and wind velocity) on the incidence of SP [7,11]. A clustering pattern of the hospital presentations of the SP cases have led to scrutinization of the climate and weather conditions.…”

OBJECTIVES:Spontaneous pneumothorax refers to the leakage of air into the space between the parietal and the visceral layers of the pleura. It occurs with or without a known lung disease. We aimed to investigate the effects of atmospheric pressure, humidity, and temperature changes on the incidence of spontaneous pneumothorax (SP). MATERIAL AND METHODS:This study included 551 patients with spontaneous pneumothorax retrospectively screened between January 2009 and December 2013. The medical data of the patients were accessed via their medical records on the hospital automation system. The atmospheric pressure, temperature, humidity rate, amount of precipitation, and wind velocity on the day of spontaneous pneumothorax were obtained from the data provided by the general directorate of meteorology. The three consecutive days on which at least 2 cases of SP presented were collectively considered as a cluster. The study data were analyzed with the SPSS version 15 software package, using the Chi-square and the Student's t tests. A p value less than 0.05 was considered statistically significant. RESULTS:Of the 552 patients included in the study, 89.3% had primary spontaneous pneumothorax and 10.7% had secondary spontaneous pneumothorax. Ninety-two percent of the patients were male and 8% were female. The mean age was 24 years. Clustering was observed in 71.7% of the study population. No significant differences were observed between yearly and monthly SP incidences. There were, however, differences between the days with SP and the days without SP with respect to atmospheric pressure, ambient temperature, wind velocity, and humidity rate. The differences between the atmospheric pressures were not statistically significant, although the differences between the ambient temperature and the humidity rate were statistically significant (p≤ 0.05). CONCLUSION:We determined that the changes in the ambient temperature and the humidity rate affected the rate of spontaneous pneumothorax by altering the meteorological conditions.

BACKGROUND: Although some authors have suggested that there is some seasonal periodicity of hemoptysis, or relation to respiratory tract infections, the association of influenza or climatic parameters with hemoptysis has been poorly investigated. Our aim was to describe the relationship between influenza and climatic parameters with severe hemoptysis that required bronchial artery embolization (BAE). METHODS: All consecutive subjects with at least one episode of hemoptysis that required BAE during a 5-y period were included. We applied a general multivariable additive seemingly causal model corresponding to a lagged variable autoregressive model with the exogenous variables as monthly mean temperature, lagged monthly mean temperature (؊1), and monthly mean influenza activity, and the number of embolizations as the endogenous variable. RESULTS: We found a significant association between severe hemoptysis requiring BAE and low monthly mean temperature and influenza activity. Other climatic factors, such as atmospheric pressure, rainfall, relative humidity, or wind speed, failed to show significant association with the occurrence of life-threatening hemoptysis. CONCLUSIONS: There is a strong long running relationship between severe hemoptysis and low monthly mean temperature. A weaker association of hemoptysis with influenza activity was also found.
