What Are the Complications of Sickle Cell Trait?
Discussion Sickle cell disease (SCD) is a group of inherited blood disorders where there are abnormal hemoglobin molecules and the red blood cells take on a characteristic sickled shape instead of a rounded shape. Sickled hemoglobin provides an evolutionary advantage of giving the individual increased protection against severe and cerebral malaria. The sickled shape doesn’t move through the vascular system as well and therefore is more likely to aggregate in small vessels causing an increased risk of vaso-occlusive disease, acute chest syndrome, splenic sequestration, and priapism. There is also an increased risk of ...

What Causes Facial Nerve Palsy?
Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...

Screening of cerebral vasculopathy in sickle cell anemia children using transcranial Doppler.
Abstract Cerebral vasculopathy exposes patients to a high risk of stroke, a major complication of sickle cell disease (SCD) associated with a high risk of death and disability. Transcranial doppler (TCD) ultrasonography used to identify SCD patients at risk of stroke may contribute to significantly reducing morbidity and mortality in these patients by indicating appropriate treatment. From March 2008 to February 2013, we conducted systematic screening for cerebral vasculopathy using TCD in 572 SCD patients (including 375 SS, 144 SC, 26 S/β(0), and 27 S/β(+) thalassemia patients) aged 1-17 years in a compre...
