Distribution and incidence of degenerative spine changes in patients with a lumbo-sacral transitional vertebra.
The purpose of this prospective study was to determine the overall incidence and distribution of lumbo-sacral degenerative changes (i.e. disc protrusion or extrusion, facet degeneration, disc degeneration, nerve root canal stenosis and spinal stenosis) in patients with and without a lumbo-sacral transitional vertebra (LSTV). The study population consisted of 350 sequential patients with low back pain and/or sciatica, referred for medical imaging. In all cases CT scans of the lumbo-sacral region were obtained. In 53 subjects (15%) and LSTV was found. There was no difference in overall incidence of degenerative spine changes between the two groups. We did find, however, a different distribution pattern of degenerative changes between patients with and those without an LSTV. Disc protrusion and/or extrusion occurred more often at the level suprajacent to the LSTV than at the same level in patients without LSTV (45.3% vs 30.3%). This was also the case for disc degeneration (52.8% vs 28%), facet degeneration (60.4% vs 42.6%) and nerve root canal stenosis (52.8% vs 27.9%). For spinal canal stenosis there was no statistically significant difference between the two categories. In conclusion, our findings indicate that an LSTV does not in itself constitute a risk factor for degenerative spine changes, but when degeneration occurs, it is more likely to be found at the disc level above the LSTV.

Recurrent hepatic hydatid disease with secondary splenic infestation.
Hydatid disease caused by Echinococcus granulosus is a common problem throughout the world, but is rarely encountered in the Western Countries. The liver and lungs are the most frequently involved organs in hydatid disease. The cyst may become very large and rupture. Abdominal, pelvic and pleural dissemination due to spread of parasitic contents may follow. Splenic involvement in hydatid disease is uncommon, representing less than 2% of all human infestations by Echinococcus. We report a recurrent liver hydatidosis with secondary splenic infestation.
