To report our data of cases of failed back surgery syndrome (FBSS) and surgical and nonsurgical etiologies. ⋯ The failure of back surgery remains a challenge for the surgeons. There is an incessant search for the causes and the action mechanisms of this syndrome and the best method of treatment.

To evaluate the diagnostic usefulness of cerebral spinal fluid (CSF) cellularity, protein, neutrophils, glucose and lactate for detection of postoperative bacterial meningitis. ⋯ The CSF glucose, lactate, and cellularity can be used for the diagnosis of bacterial meningitis. Moreover, it can be helpful to differentiate bacterial from aseptic meningitis.

To establish reference values for measures of blood flow velocities and impedance indexes in healthy individuals through conventional transcranial Doppler (TCD) and to observe their variations in relation to the age and sex. ⋯ TCD was shown useful in the evaluation of hemodynamic cerebral for our population. Our results are similar to the other studies, so much in the reference values as in relationship with the age and the sex.

A case of isolated velopalatine paralysis in an 8-year-old boy is presented. The symptoms were sudden-onset of nasal speech, regurgitation of liquids into the nose and dysphagia. ⋯ Infectious serologies disclosed an antibody arrangement towards parvovirus B19 that was typical of recent infection. In the absence of other positive data, the possibility of a correlation between the tenth nerve palsy and parvovirus infection is discussed.

Spinal cord injury without radiologic abnormalities is a rare condition that occurs more frequently in children and contributes to a high rate of morbidity among these patients. We report the case of a five-month-old infant, victim of automobile accident, who was brought to our service with a sensitive level in T2 and bilateral crural paraplegia. ⋯ Magnetic resonance image showed complete spinal cord transection and spine avulsion in the segment between T3 and T7. We discuss this pathology according to its epidemiology, pathophysiology, diagnosis, treatment and prognostic aspects.
