Late occurrence of additional ocular and intracranial pathologies in the linear naevus sebaceous (Feuerstein-Mims) syndrome.

The linear naevus sebaceous syndrome of Feuerstein-Mims belongs to the phacomatoses and classically is composed of a linear cutaneous lesion associated with mental retardation and epilepsy, sometimes also with ocular dystrophies. During an unusually long follow-up of 32 years of such a case, which is reported here, the late occurrence of additional ocular and intracranial pathology are demonstrated: conjunctival and bulbar tumours with progressive deterioration of visual acuity, bilateral intracranial arachnoidal cysts, dilatation and tortuosity of the middle cerebral artery. As a consequence of these observations the prognosis in cases with this syndrome has to be given with special caution.

Management and surgical outcome of suprasellar meningiomas.

The authors analyse 22 cases of suprasellar meningiomas, drawing attention to factors influencing on the surgical outcome. In all but one case, symptomatology began with progressive visual failure in one eye. Bilateral anosmia was noted in 4 patients with large tumour.

Argon laser lesions of the rabbit iris: quantitative aspects.

The destructive effect of nonperforating argon laser coagulations in the brown irides of rabbits was studied with quantitative histological methods. Power, spot size, and exposure time were systematically varied. The lateral and axial extensions of the crater and the denaturation of the adjacent tissue were studied.

Reconstruction of the orbital roof by acrylic prosthesis.

Presentation of two cases of open orbital roof fracture with destruction of all the orbital roof extending from the fronto-maxillo region to the spina orbitalis. After a first emergency neurosurgical treatment, a cast of the excised soiled bone fragment was taken and identical replica was made from methylmethacrylate. In a second surgical procedure, the resine mould was set in place by endocranicl approach, and was fastened firmly to the surrounding bone with wire sutures.
