Semicircular canal orientation in the adult resting rabbit.

Photographs of rabbits in the alert resting position were used to record head position. Semicircular canals were surgically exposed and points measured along each canal were used to compute the best-fit plane using a least-squares method. Computations of mean best-fit planes showed that the horizontal canals were not carried horizontally in the rabbit. The anteromedial edges were superior by 16 degrees. The anterior canals were vertically oriented and made an angle of 43 degrees to the sagittal plane. The posterior canal was tipped in the anterior direction slightly and also made an acute angle (26 degrees) with the frontal plane. Rabbit semicircular canals deviated significantly from orthogonality. The range was 86 degrees (anterior canals) to 133 degrees (posterior canals). Thus, there were no co-planar canals. Such semicircular canal geometry has implications for the neural circuitry controlling posture in the rabbit.

[Treatment of pure stage one ovarian dysgerminoma in young women. Report of a case and review of the literature].

The authors report a case of stage 1 ovarian dysgerminoma (OD) in a young woman aged 23 who subsequently underwent conservative surgery. A review of the literature shows that in 80% of cases this neoplasia is present at stage 1A and 85% of patients are under 30, with a 5-year survival rate of 95%. OD treatment should therefore be personalized and, although it continues to be controversial, most authors agree that in young women in whom the disease is limited to one ovary, without lymph node metastases, treatment can be restricted to monolateral adnexectomy, thus assuring the patient's future fertility.

[Benign tumors and pseudotumors of temporo-mandibular joint: radiologic aspects].

Benign tumors and tumor-like lesions that involve temporo mandibular joint are very rare. Those more frequent are osteochondroma, chondroma, osteoma, pigmented villonodular synovitis and synovial chondromatosis. The Authors report six cases of patients affected by these pathologies in which imaging, such as TC, MRI and/or ortopantomography have been useful to have a diagnosis.
