Diabetes insipidus and increased serum levels of leptin and lactate-dehydrogenase (LDH) in an adolescent boy with a primary intracranial germinoma. Case report and an endocrinological revaluation of literature.

A 16-year-old boy presented with a four-month history of polyuria-polydipsia and a diplopia which had reverted after treatment. The neuroimaging studies performed had been strongly suggestive of an optic nerve glioma, while endocrinological investigation (beta-hCG 420 IU/L) has lead to the correct diagnosis later confirmed at the immunohystochemical analysis performed at biopsy. The high serum level of hCG was unaffected by bromocriptine nor octreotide, while the PRL level (80.0 microg/L) was reduced only by bromocriptine. Among the several tumor markers which may be secreted by such lesions, ours is the first reported case of an elevation of serum LDH for a primary intracranial germinoma. Moreover, the elevated value of serum leptin reported by us might be due to the insensitivity of the hypothalamic structures to endogenous leptin.

[Lymphocytic infiltration in cerebral gliomas].

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.

A rare case of Toxocara canis arachnoidea.

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.

Intracerebral haemorrhage: criteria for prognosis on the grounds of clinical and CT data.

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.

Prognostic significance of lymphoid infiltration in cerebral malignant gliomas.

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.

The operation of arthrodesis for malformations of the occipito-atloid joint, according to Gilles Bertrand.

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.

Traumatic aneurysms of the carotid artery. Case report.

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.

[Post-traumatic bony bridges of the spinal column].

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.
