[The pneumocephalus in cranio-cerebral trauma (author's transl)].

The accident surgeon is often surprised to see unusual intracranial translucencies on X-ray films of persons with skull injuries. Inexperienced physicians are often unable to immediately identify these translucencies as air enclosures in the intracranial cavity. Physicians not acquainted with pneumoencephalography commonly employed so far in neurological examinations will find it difficult to recognize in the accumulated air the contours of the ventricular, cerebral convolution and cisternal systems. Hence, the relatively rare event of air penetrating into the intracranial space as a result of an injury, is described here on the basis of two of our patients.

[Basilar artery thrombosis (author's transl)].

Arteriosclerosis is the most common cause of basilar artery thrombosis. Rarely basilar occlusions are observed after cerebral concussion and hyperextension of the neck; occasionally they are founded in craniocervical dysplasia, arteritis and hypercoagulability of blood.--Clinical data and differential diagnostic aspects are demonstrated in 4 own cases and the present literature. Characteristics of clinical symptomatology are discussed with respect to the sites of predilection in distal and proximal part of basilar artery. Angiography examination is the most important diagnostic method and shows prognostic indications by demonstration of collaterals.--The treatment consists of inhibition of blood viscosity, reduction of perifocal edema and stabilization of blood-pressure.

[The stiff-man syndrome. A case report with regard to clinical, electromyographical and pharmacological signs (author's transl)].

Our electromyographical findings show no evidence for a spinal or neurogenic origin of muscle stiffness in stiff-man syndrome. It is assumed that the tonic muscle rigidity is induced by abnormal impulses from the brainstem. The measured latencies of electrically induced muscle spasm in the legs are in accordance with this hypothetic site of origin. Muscle stiffness and spasm are decreased by the GABA derivative Baclofen as well as by Clonacepam, which is preferable to Diazepam because of less intense sedation. Spasms are increased by Chlorimipramine which may by used as a provocative test in uncertain cases. These pharmacological influences suggest an imbalance between a gabaminergic inhibitory and a noradrenergic and/or serotoninergic excitatory neuronal system.
