Abstract Background Spontaneous epidural hematoma commonly occurs in patients who have coagulopathy, vascular tumors, and vascular malformations. The association between this entity and maxillofacial infection is rare. Case Presentation A 17-year-old male patient presented to our emergency with a decreased level of consciousness. The patient had a history of nasal discharge and fever for about four days. The brain Computed tomography scan revealed a hematoma that was treated with craniotomy. The hematoma culture was positive for staphylococcus aureus, so antibiotic therapy was started for the patient and continued for six weeks. All the symptoms were fully recovered and the patient was discharged without any neurological deficits. Although spontaneous epidural hematoma following craniofacial infection is rare, prompt imaging and hematoma evacuation have been found with higher rates of favorable outcomes and Markley decreased mortality. Conclusion Distinguishing between hematoma and cerebral abscess is slightly difficult. However, consideration of surgery facilitates reaching a reliable diagnosis and treatment.

Background Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally, and specifically in Iran. Accurate assessments of Coronary heart disease (CHD) incidence is very necessary for public health. In current study we aimed to investigate the incidence of CHD and importance of several classical, modifiable and un-modifiable risk factors for CHD among an urban population in eastern Iran after 6 years of follow-up. Methods The population of MASHAD cohort study were followed up for 6 years, every 3 years in two step by phone and who reported symptoms of CVD were asked to attend for a cardiac examination, to estimate the incidence of CHD with 95% confidence interval (95% CI) as well multiple logistic regression analysis was performed to assess the association of several baseline characteristics with incidence of CHD event. Evaluation of goodness-of-fit was done using ROC analysis. CHD cases divided into four different classes which include: stable angina, unstable angina pectoris, myocardial infarction and sudden cardiac death. Results In the six years' follow-up of Mashhad study, the incidence rate of all CHD event in men and women in 100,000 people-years with 95% confidence intervals were 1920 (810-3030) and 1160 (730-1590), respectively. The areas under ROC curve (AUC), based on multivariate predictors of CHD outcome, was 0.7825. Conclusion Our findings indicated that the incidence rate of coronary heart diseases in MASHAD cohort study increases with age as well as our final model designed, was able to predict approximately 78% of CHD events in Iranian population.
