Anatomic variation of the abducens nerve in a single cadaver dissection: the "petrobasilar canal".

Anatomic variations of the petrosphenoid ligament, Dorello's canal and the course of the abducens nerve have been extensively described over the past years. In the present report of a single cadaver dissection, we describe an unusual course of the abducens nerve at the level of the petrous bone. The right abducens nerve did not enter Dorello's canal, but ran below the petrous bone through a narrow canal in the petrobasilar suture, which we called the "petrobasilar canal". No anatomic variations of the left abducens nerve were noted.

Osteopathic manipulation as a complementary treatment for the prevention of cardiac complications: 12-Months follow-up of intima media and blood pressure on a cohort affected by hypertension.

BACKGROUND: Aim of the present study was to investigate the association between osteopathic treatment and hypertension. METHODS: The design was a non-randomized trial including consecutive subjects affected by hypertension and vascular alterations, using pre-post differences in intima-media thickness, systolic and diastolic blood pressure as primary endpoints. Statistical analysis was based on univariate t tests and multivariate linear regression. RESULTS: A total of N = 31 out of N = 63 eligible subjects followed by a single cardiologist received osteopathic treatment in addition to routine care. Clinical measurements were recorded at baseline and after 12 months. Univariate analysis found that osteopathic treatment was significantly associated to an improvement in all primary endpoints. Multivariate linear regression showed that, after adjusting for all potential confounders, osteopathic treatment was performing significantly better for intima-media thickness (delta between pre-post differences in treated and control groups: -0.517; 95% c.i.: -0.680, -0.353) and systolic blood pressure (-4.523; -6.291, -2.755), but not for diastolic blood pressure. CONCLUSION: Our study shows that, among patients affected by cardiovascular disorders, osteopathic treatment is significantly associated to an improvement in intima-media and systolic blood pressure after one year. Multicentric randomized trials of adequate sample size are needed to evaluate the efficacy of OMT in the treatment of hypertension.
