Hemoptysis as a rare manifestation of missed blunt thoracic aorta injury, a case report.

Introduction And Importance: Blunt thoracic aorta injury is one of the most fatal injuries in multiple trauma patients and most of these injuries lead to death at the scene. Some patients remain undiagnosed because of the lack of specific symptoms for these injuries. Hemoptysis as a presentation of a neglected blunt aortic trauma is a very rare condition.

A case series of pediatric COVID-19 with complicated symptoms in Iran.

People in different age groups are susceptible to SARS-CoV-2 infection as a newly emerging virus. However, the clinical course, symptoms and disease outcome vary from case to case. Although COVID-19 is usually milder in children than adults, some studies reported nonspecific symptoms.

Evaluation of hemodynamic properties of cerebral venous drainage in patients with multiple sclerosis: a case-control study.

Background: The purpose of this study was to compare patients with multiple sclerosis and healthy control subjects as regards hemodynamics of cerebral venous drainage.

Material/methods: Between December 2012 and May 2013, 44 consecutive patients with multiple sclerosis and 44 age- and sex-matched healthy subjects underwent the B-mode, color Doppler, and duplex Doppler evaluations of the internal jugular vein (IJV) and vertebral vein. The following four parameters were investigated: IJV stenosis, reversal of postural control of the cerebral venous outflow pathways, absence of detectable blood flow in the IJVs and/or vertebral veins, and reflux in the IJVs and/or vertebral veins in the sitting or supine position.

Germline BRCA2 mutations and the risk of esophageal squamous cell carcinoma.

The incidence of esophageal squamous cell carcinoma (ESCC) is very high among the Turkmen population of Iran. Family studies suggest a genetic component to the disease. Turkmen are ethnically homogenous and are well suited for genetic studies.
