Olfactory function after mild head injury in children.
نویسندگان
چکیده
Olfactory impairment has been shown to be linked to head injury. In addition, it is believed that measurement of olfactory function after head trauma represents a sensitive tool for measuring frontal brain damage. Aim of the study was to evaluate the effect of mild head trauma in children on olfactory function over a time period of up to 1 year after head trauma. The olfactory function of 114 children who suffered mild head trauma according to the Glasgow Coma Scale was assessed 3 times with an interval of 4 months. In addition, healthy, age-matched controls were tested for comparison of olfactory function. Patients scored significantly lower on the odor threshold test compared to the control group-but still within normal range. Between the 2 groups, no difference was found for suprathreshold testing. Neither olfactory threshold scores nor olfactory discrimination scores changed significantly over the study period of 1 year. This data prove an impact of mild head trauma on olfactory function of children. It seems unlikely that children who suffered mild head trauma will become hyposmic or anosmic.

Background: The present study assesses independent predictors of clinically important traumatic brain injury (ciTBI) in order to design a prognostic rule for identification of high risk children with mild head injury. Materials and Methods: In a retrospective cross-sectional study, 3,199 children with mild traumatic brain injury (TBI) brought to emergency ward of three hospitals in Tehran, Iran...
متن کاملLong term psychosocial outcomes after mild head injury in early childhood.
OBJECTIVES The question of whether any adverse cognitive or psychosocial outcomes occur after mild head injury in early childhood has evoked considerable controversy. This study examined mild head injury before age 10 and potential differences in late childhood/early adolescence as a function of severity of mild injury and age at injury. METHODS A fully prospective longitudinal design tracked...

Purpose: Spinal cord injury is a global public health issue that results in extensive neuronal degeneration, axonal and myelin loss and severe functional deficits. Neurotrophic factors are potential treatment for reducing secondary damage, promoting axon growth, and are responsible for inducing myelination after injury. Olfactory ensheathing cells (OECs) and minocycline have been shown to promo...

Introduction: Radiotherapy is a common treatment modality for patients with head and neck malignancies. As the nose lies within the field of radiotherapy of the head and neck, the olfactory fibers and olfactory receptors may be affected by radiation. The aim of this study was to evaluate changes in olfactory threshold in patients with head and neck malignancies who have received radiation to th...
