A significant pain reduction was achieved in 59.4%. Significantly, after a double-level operation, more patients suffered persisting neck pain (P = 0.002) high throughput screening compounds compared with all patients being operated.
Conclusions.
Zygapophysial joints are a possible source of postoperative pain after anterior cervical spine surgery. Persistent and therapy-resistant neck pain occurs more often in patients after double-level operation. Radiofrequency neurotomy can provide an effective treatment for persistent neck pain after ventral cervical spine surgery.”
“Unna and Miescher nevi show
very different morphologic features. The main difference is that melanocytes involve mainly the papillary dermis in Unna nevi, whereas they widely penetrate the reticular dermis in Miescher nevi. The reason for this behavior is not totally understood, but anatomical location might play a role, since because Unna nevi are mainly found on the trunk, whereas Miescher nevi are mainly found on the face. We decided to test this hypothesis in relative easy way: dermis from the frontal, temporal, maxillary, and mandibullary regions derives
from the neural crest, whereas the dermis of the parietal/occipital regions originates from the paraxial mesoderm (somites and somitomeres). Therefore, we studied the morphology of 137 acquired melanocytic GSK621 datasheet nevi from the head and neck and classified their locations in 7 areas: occipital, temporal, parietal, frontal, face, high neck, and low neck. From such areas, we distinguished 4 groups: area A (parietal + occipital + low neck); area B (face + temporal + frontal
+ high neck); area 1 (parietal and occipital); and area 2 (temporal and frontal). In region A, 97.30% of the nevi were of Unna type. In region B, 89.00% were of Miescher AZD6244 type. Region A had 76.60% of Unna type nevi, whereas region B had 98.89% of Miescher nevi. In area 1, 100% of the nevi were of Miescher type. In area 2, 86.67% of the nevi were of Unna type. Region 1 had 86.67% of the cranial Unna nevi, whereas region 2 had 100% of the cranial Miescher nevi. Moreover, 90.9% of the nevi from the low neck were of Unna type. In the high neck, 20% of nevi were of Unna type. Finally, 90.90% of Unna nevi were in the low neck, whereas 80% of Miescher nevi were in the high neck. We concluded that these findings supported the hypothesis that the embryologic differences of these areas of head and neck might play a role in the morphology of Unna and Miescher nevi.”
“Background.
Lumbar spinal stenosis is a common condition that causes axial low back pain, radicular pain, and neurogenic claudication. Epidural steroid injections are commonly used for the treatment of radicular symptoms and neurogenic claudication associated with symptomatic lumbar spinal stenosis. No prior study has evaluated whether transforaminal or interlaminar epidural steroid injections produce better clinical outcomes.
Design.
Retrospective case control study.
