The authors report a case of left common iliac artery injury, as a complication of diskectomy, in a 57 year-old male patient, with herniated disk at L4-L5. A review shows that L4-L5 disk space is the most common site for this rare complication of lumbar disk surgery.
Data concerning a preliminary study on the prognostic significance of inflammatory infiltration in cerebral metastases are reported. Seventeen cases of operated cerebral metastases have been studied to investigate their histotype and grade of necrosis, stromal reaction, and inflammatory infiltration. Finally, the results obtained are discussed in relation to the postoperative survival rate of the patients.
The link between blood viscosity, Ht and the onset of stroke is highlighted and reports in the literature are examined. On this basic, the paper proposes an experimental model of cerebral ischaemia in the rabbit as providing a better insight into this aspect which may be highly significant, particularly in the prevention of strokes.

The authors analyse the incidence, extent and prognostic significance of lymphocytic infiltration in 80 cases of operated cerebral gliomas (61 high- and 19 low-grade gliomas). The results obtained are discussed in relation to the data previously reported by the literature.
The Authors present a case of Toxocara canis arachnoidea located in the cervical zone. The rarity of the case and the extreme rarity of the position are emphasized. In fact in medical literature there exists a description of only one similar case which was also observed by one of the authors.
The Authors report analyses on 83 cases of brain haemorrhage which were conducted over a period of 6 years. On the basis of previous studies made by the same authors, a selection was made from patients whose survival index rating did not exceed 8.1. These patients were treated only with medical and reviving therapies. In this work we attempt to formulate some considerations regarding the prognosis of brain haemorrhage on the basis of clinical and tomodensitometric data.
Data concerning a study on lymphoid infiltration in 61 cerebral malignant gliomas are reported. Lymphoid cellular infiltrates were found in 28 cases (45.9%): 8 (13.1%) with marked and 20 (32.8%) with slight infiltration; the remaining 33 cases (54.1%) did not exhibit lymphoid infiltration. The mean survival time (+/- standard deviation) of patients harboring gliomas with marked lymphoid infiltration was 20.5 (+/-19.9) months, and that of patients with slight lymphoid infiltration in their glioma was 10.3 (+/- 7.5) months; those patients having gliomas without lymphoid cellular infiltrates showed a mean survival time (+/- standard deviation) of 7.2 (+/-6.1) months.
Malformations of the occipito-vertebral hinge destabilize the bones and injure the neural structures of the bulbo-spinal junction and of the cervico-spinal cord. The Authors have found the Gilles Bertrand intra-articular C/1-C/2 bilateral arthrodesis to be an extremely efficient surgical procedure for stabilizing the occipito-atlo-axial region, producing a relative lowering of the odontoid and relieving pressure in the occipito-atloid region. Excellent post-operative results derive from the relatively easy and non-destabilizing operative procedure. No deaths have been recorded in connection with this operation. This contrasts with the traditional occipito-atloid pressure-relieving procedure (either with or without opening of the dura mater), a procedure which, in addition to not stabilizing the upper cervical spine, sometimes results in the patient's death.
The Authors report a rare case of traumatic aneurysm of the internal carotid artery observed in a 19-year-old man after a car accident. The aneurysm was recognized by cerebral angiography performed immediately after trauma and clipped to avoid delayed rupture. The literature on traumatic aneurysms is reviewed.
The Authors, on the base of Vackeneim's pathogenetic hypothesis about a case of post-traumatic bone bridges of the spine, describe three cases observed and examine the etiopathogenesis of this extremely rare pathology.
