Paravertebral
titanium
rod migration represents an unusual and potentially fatal complication of vertebral stabilization surgical procedures. This condition, which requires a prompt and rapid diagnosis, is often mistaken for other more common diseases, or scotomized. We present a case of a 69 years old female affected by a non-
Hodgkin lymphoma
with evidence of migration of both rods five years after the posterior stabilization procedure for a pathological L3 fracture. Unusual clinical onset was represented by a left S1 radiculopathy without other symptoms. For several months, the symptoms were attributed to a possible radicular infiltration by the lymphoma. We conclude that paravertebral rod migration could happen not only within the spinal canal, but could also rarely damage blood vessels or parenchymal organs. This is generally a long-term complication, probably due to an insufficient fixation. Strict long-term follow-up monitoring is mandatory since this unusual complication can mimic other more common pathological conditions.

This study examines the ability of optically-excited
titanium
dioxide nanoparticles to influence voltage-gated ion channels in retinal horizontal cells. Voltage clamp recordings were obtained in the presence and absence of TiO
2
and ultraviolet laser excitation. Significant current changes were observed in response to UV light, particularly in the -40 mV to +40 mV region where voltage-gated Na
+
and K
+
channels have the highest conductance. Cells in proximity to UV-excited TiO
2
exhibited a left-shift in the current-voltage relation of around 10 mV in the activation of Na
+
currents. These trends were not observed in control experiments where cells were excited with UV light without being exposed to TiO
2
. Electrostatic force microscopy confirmed that electric fields can be induced in TiO
2
with UV light. Simulations using the
Hodgkin
-Huxley model yielded results which agreed with the experimental data and showed the I-V characteristics of individual ion channels in the presence of UV-excited TiO

.
