Influence of weather and air pollution on the occurrence of idiopathic pulmonary embolism in the region of Sousse (Tunisia).

Pulmonary embolism (PE) is the most serious manifestation of thromboembolic conditions. Its incidence varies considerably between countries, suggesting its interaction with the external environment. To analyze the influence of climate and air pollution on the occurrence of idiopathic PE in the region of Sousse (Tunisia). A total of 142 patients with idiopathic PE at two academic hospitals in Sousse (Tunisia) were enrolled in the study over a 7-year period. An analysis of two time series (environmental data and PE cases) was performed. Climatic data were collected from the National Institute of Meteorology. Air pollution data were obtained from the modeling platform of the National Agency for Protection of the Environment. The year 2015 was marked by the occurrence of the highest number of cases (24.6%). A statistically significant decrease in PE risk of 41.9% was observed during the summer with an OR of 0.59 (95% CI [0.36-0.94] and p = 0.026), compared with other seasons. Poisson GLM regression showed a significant increased risk of PE of 3.3% for each 1 °C temperature drop. After multiple binary logistic regression, the elevation of PM10 concentration was independently associated with an increased risk of PE (p < 10-3, OR 79.55, 95% CI [42.28-149.6]). Some environmental parameters may predispose to the onset of idiopathic PE. Understanding their accurate influence may have preventive and curative implications.

Chronic Pain following Chest Trauma: Prevalence, Associated Factors, and Psychosocial Impact.

Background: Chronic pain (CP) is a real public health concern. It is a common cause of poor quality of life and workplace absenteeism. It is well studied in many medical and surgical fields. However, only few data are available as regards to its occurrence in trauma patients. Purpose: To assess the prevalence, associated factors, and psychosocial impact of CP following chest trauma. Methods: This is an observational, descriptive, and analytic cross-sectional study performed in a Tunisian department of anesthesia and intensive care over a two-month period. Adult patients admitted one year ago for isolated chest trauma were enrolled. Data were collected by a phone interview. Studied variables were sociodemographic characteristics, traumatic injuries and their management, the occurrence of CP, and its psychosocial impact. CP was diagnosed by the Brief Pain Inventory (BPI) considering an evolution period of at least 3 months. Its impact was assessed by the BPI and the Posttraumatic stress disorder Checklist Scale (PCLS). Results: Fifty-four patients were included in the study. The prevalence of CP was 79.6%. The average CP intensity was 3.18 ± 1.4. It was neuropathic in 90.7%. Its main associated factors were pleural effusion (p=0.016), time to ICU admission (p=0.016), time to ICU admission (p=0.016), time to ICU admission (p=0.016), time to ICU admission (. Conclusion: CP following chest trauma is frequent and severe requiring preventive measures such as high risk patients screening, better management of acute pain, and a multidisciplinary approach for patients with diagnosed CP.

Relationship between Hand Eczema Severity and Occupational Stress: A Cross-Sectional Study.

BACKGROUND: Stress has been recently implicated as a contributing factor of hand eczema (HE) severity. However, published data are both rare and contradictory justifying the need of further research. The purpose of this study was to evaluate the relation between stress and HE severity. METHODS: This is a cross-sectional study enrolling all patients who have been attending the Dermato-allergology unit of Farhat Hached University Hospital of Sousse over a period of one year. The HE severity was assessed by the Osnabrück Hand Eczema Severity Index (OHSI). The stress level was assessed by the Perceived Stress Scale-10 (PSS-10) in its validated Arabic version. RESULTS: During the study period, 109 participants meeting the inclusion criteria were identified. The mean age was 40 ± 9.9 years with a sex-ratio of 0.8. Severe eczema was found in 76 participants (69.7%). A high level of perceived stress was found in 18.3% of cases. A statistically significant association was noted between HE severity and the high level of perceived stress (p=0.039, OR = 4.46, 95% CI [0.96-20.59]) and the number of dependent children ≥3 (p=0.0039, OR = 1.92, 95% CI [0.51-7.22]). Leisure activity was found to be a protective factor against HE severity (p=0.031, OR = 0.27, 95% CI [0.09-0.80]). CONCLUSION: Although the link between the severity of eczema and atopy, wet work, and contact with irritants and allergens is well known, the relation remains questionable for other factors including stress.
