Acute respiratory distress syndrome after spontaneous rupture of a large pulmonary hydatid cyst in a 17-year-old male: A case report.

Pulmonary hydatid cysts (PHC) and their complications are still a health concern in endemic countries. Here we described a 17-year-old male presented with a large PHC with a spontaneous rupture. He developed acute respiratory distress syndrome (ARDS) requiring mechanical ventilation. He was treated with albendazole, broad-spectrum antibiotics, and corticosteroids. The patient's general condition did not allow any attempt for surgical resection of the cyst. He was discharged in stable condition after one month and referred to a thoracic surgeon for resection of the cyst. As far as we know ARDS after hydatid cyst rupture was rarely reported, and through this case report we aimed to raise awareness of this possible life-threatening complication.

Prevalence and predictors of slow coronary flow phenomenon in Kermanshah province.

Introduction: This study was conducted to investigate prevalence and predictors of slow coronary flow phenomenon (SCF) phenomenon. Methods: This cross-sectional study was performed at Imam Ali Cardiovascular Hospital affiliated with the Kermanshah University of Medical Sciences (KUMS), Kermanshah province, Iran. From March 2017 to March 2019, all the patients who underwent coronary angiography were enrolled in this study. Data were obtained using a checklist developed based on the study's aims. Independent samples t tests and chi- square test (or Fisher exact test) were used to assess the differences between subgroups. Multiple logistic regression model was applied to evaluate independent predictors of SCF phenomenon. Results: In this study, 172 (1.43%) patients with SCF phenomenon were identified. Patients with SCF were more likely to be obese (27.58±3.28 vs. 24.12±3.26, P <0.001), hyperlipidemic (44.2 vs. 31.7, P <0.001), hypertensive (53.5 vs. 39.1, P <0.001), and smoker (37.2 vs. 27.2, P =0.006). Mean ejection fraction (EF) (51.91±6.33 vs. 55.15±9.64, P <0.001) was significantly lower in the patients with SCF compared to the healthy controls with normal epicardial coronary arteries. Mean level of serum triglycerides (162.26±45.94 vs. 145.29±35.62, P <0.001) was significantly higher in the patients with SCF. Left anterior descending artery was the most common involved coronary artery (n = 159, 92.4%), followed by left circumflex artery (n = 50, 29.1%) and right coronary artery (n = 47, 27.4%). Body mass index (BMI) (OR 1.78, 95% CI 1.04-2.15, P <0.001) and hypertension (OR 1.59, CI 1.30-5.67, P =0.003) were independent predictors of SCF phenomenon. Conclusion: The prevalence of SCF in our study was not different from the most other previous reports. BMI and hypertension independently predicted the presence of SCF phenomenon.
