Haemodynamic Changes in Patients with Whiplash Injury Measured by Transcranial Doppler Sonography (TCD)

The daily increasing number of cervical whiplash injuries presents ever-greater requirement for vertebrobasilar diagnostics. A cervical spine injury, which is quite frequent injury, may occur during a fall, or industrial, traffic, sport or war injury. Transcranial Doppler (TCD) sonography with Transcan 3-D EME device and 2 MHz probe was used for the assessment of vertebrobasilar circulation in patients with a whiplash injury of the cervical spine, that occurred mostly in car accident. This study includes 47 patients with clinically verified cervical spine trauma with x-ray evidence of no bone lesion. The patients were examined by TCD within a month, and then six months following the accident. The obtained values were compared to normal blood flow velocities and correlated with the severity of clinical picture. During the first month after the injury, statistically significant disturbances in the vertebrobasilar circulation were recorded, such as the increase in mean blood flow velocities in AVL (68%), AVR (62%) and BA (51%) (mostly as spasam). Six months later, normal findings were obtained in about 50% of the vessels, whereas in rest of the patients vasospasam persisted in one, two or all examined blood vessels. TCD of the vertebrobasilar circulation was found to be a very useful method in the diagnostics and follow–up of patients with a whiplash injury

Transcranial Doppler in Smoking Relapse Prevention Strategy

Nicotine dependence is a progressive, chronic, relapsing disorder. Nicotine is the principal and most potent psychopharmacologically active component of tobacco smoke. Through activation of nicotine receptors in the central nervous system, nicotine can lead to tolerance and dependence. Cessation of smoking is followed by severe pathophysiologic withdrawal and by long-term craving. TCD measurement of cerebral blood flow velocity (BFV) and nicotine dependence degree measured by Fragestrom questionnaire was analyzed in relation to smoking relapse. This study includes 47 participants (25 females and 22 males) included in Breathe Free Plan To Stop Smoking in Non Smoking School in Zagreb.12 month following the end of treatment participants were divided in three groups: continued abstinence, interrupted abstinence and non abstinence. High nicotine dependence combined with TCD pathological finding significantly discriminated successes and failures, suggesting that smokers with pathological TCD need specific therapeutic approach with more social support, individualized coping skills and cognitive restructuring. Measuring cerebral flow velocity by transcranial Doppler in smokers showed the practical validity in prediction of smoking relaps
