Forty-eight adult male Sprague-Dawley rats were used. A 5-mm-diameter circular craniectomy was performed in the left parietal bone. Animals were divided into 6 experimental groups of 8 rats, each group receiving
a different treatment: control (no substance added), Spongostan, Bio-Oss, FGF, FGF + Spongostan, and FGF + Bio-Oss. Animals were killed 12 weeks after surgery.
Descriptive histology and stereology were used, the latter to measure the volumes of regenerated bone and Bio-Oss remaining in the defect. Analysis of variance was used to determine differences in bone regeneration between groups, and Mann-Whitney U test was used to compare the Aurora Kinase inhibitor volume of remaining Bio-Oss particles.
Histologically, the control defects
behaved like critical size defects, showing incomplete bone regeneration. Only the FGF + Spongostan group achieved nearly complete bone regeneration. Bio-Oss particles seemed to reduce centripetal bone regeneration. Spongostan by itself did not interfere with spontaneous bone selleck inhibitor healing.
Stereologic measurements of the volume of new bone growth, measured in cubic millimeter, were as follows: control group, 3.86 +/- 1.03; Bio-Oss, 2.26 +/- 1.06; Spongostan, 3.00 +/- 0.81; FGF, 3.99 +/- 1.85; FGF + Bio-Oss, 3.02 +/- 1.88; and FGF + Spongostan, 8.93 +/- 1.28. Analysis of variance showed a statistically significant difference between the FGF + Spongostan group and the other groups (P < 0.001). Comparison among the other groups did not show
significant differences.
Fibroblast growth factor 1 with a Spongostan carrier has shown great efficacy for bone regeneration in cranial critical size defects in rats. Copanlisib cost Bio-Oss did not produce a regenerative effect, either alone or with FGF-1.”
“Eagle’s syndrome is an uncommon sequela of elongation of the styloid process. Symptoms include recurrent throat pain and anterolateral neck pain, with referred pain to the ear. We report a 65-year-old man who presented with bilateral glossopharyngeal neuralgia. We performed three-dimensional computed tomography which revealed that the right styloid process was 35.1 mm and the left process was 29.6 mm, leading to diagnosis of an elongated styloid process, i.e. Eagle’s syndrome. Because the patient refused surgical treatment, conservative therapy was selected. Oral gabapentin, stellate ganglion block, and 8 % lidocaine spray on the tonsillar branches of the glossopharyngeal nerve resulted in complete resolution of the paroxysms of pain in approximately 3 weeks.”
