Cytological, histological and ultrastructural findings of a pure benign Sertoli cell tumor.

A pure Sertoli cell tumor of the testis in a 26-year-old man is reported, with cytologic, histologic and ultrastructural findings. The preoperative cytological diagnosis allowed a conservative surgical approach.

[Interceptive therapy of Class III]. / Terapia intercettiva delle III Classi.

The early morphofunctional reequilibration of skeletal III Class pattern is one of the keys of resolution of this complex and dramatic pathology. Long-term controls suggest the use of Quad-Helix and III Class elastic traction as soon as possible, in order to correct premaxillary and maxillary hypoplasia eventually complicated by a posterior cross-bite. The simplicity of interceptive therapy is inversally proportional to the benefits that could be obtained and which are reliable and stable.

[Myelography in obstetrical paralysis of the brachial plexus]. / La mielografia nelle paralisi ostetriche del plesso brachiale.

The use of myelography in obstetric palsies of brachial plexus is aimed at diagnosing root avulsion. This kind of lesion appears as the disappearance of the slightly transparent nerve roots which might be combined either with pseudomeningocele or with deformation of radicular pouch. In our study we considered 69 operated patients who had previously undergone myelography. In 74.2% of cases myelographic findings were confirmed at surgery. False positives and false negatives were 9.7% and 3.2%, respectively. Incorrect diagnoses were made in 12.9% of cases, because of misread lesions and incorrect evaluation of their location, usually at the cervico-dorsal junction. No side-effects were observed. Myelography appears thus to be extremely useful for both the preoperative evaluation and the choice of surgery in newborn children with obstetric palsy of the brachial plexus.
