[Changes in sleep pattern in presenile and senile dementia (author's transl)].

Analysis of polygraphic recordings of nocturnal sleep in 21 patients with "degenerative" dementia led to the identification of two types of tracing. The first type was characterised by morphologically normal sleep with more marked quantitative changes than those caused by simple aging. In the second type, the criteria of identification of the physiological stages of sleep disappeared, requiring special definition of the E.E.G. appearances seen. These two types corresponded to two different stages of advancement and probably were indicative of the progressive extension of lesions.

[Value of computerized axial tomography in cranio-cerebral injuries].

Since May 1975 was have been working in the field of C.A.T. and its application to study head injuries. We are presenting differents groups of patients studied by C.A.T. I. -- DATA OF C.A.T. IN THE CASES OF EMERGENCY AND IMMEDIATE POST-OPERATIVE FOLLOW-UP OF HEAD INJURIES A) EMERGENCY STATE As soon as the clinical state of an head injured patient was supposed to need an operation, C.A.T. was realized; so differents abnormal scanners may be observed: 1. epidural hematoma, 2. subdural hematoma, 3. intra-cerebral hematoma, 4. acute subdural hematoma or contusion. We must do some comments: -- The Emi-scanner is pre-eminent in showing the exact topography of the lesion : so, the flap is easier to realise. -- In most cases the Emi-scanner is easier to interpret than angiogram for example contusion and hematoma. We know the goods results in hematomas and the poors results in surgery of contusions. -- But the senior advantage of C.A.T. is to provide all the informations in the totality of skull content. Emi-scanner shows bilateral lesions, ipsilateral lesion. C.A.T. is pre-eminent in showing the presence of this two lesions, more accurately than senior methods of investigations, so C.A.T. permits emergency neurosurgical treatment. B) C.A.T. AND FOLLOW-UP Repeated studies at post-intervals can be accomplished without risk to the patient, thus making follow-up simpler and more effective to the neurosurgical attitude. C) POST-OPERATIVE CONTROL AND C.A.T. Post-operative complications are always hard to diagnosis. C.A.T. is painless, quick and safe, and easier to interpret than an angiogram. II -- SEQUELLAE STADE AND C.A.T. In this field certains advantages of C.A.T. are immediatly apparents. In most cases the C.A.T. is the best screening method. Patients carried out are: -- psychiatric troubles, -- post-traumatic epilepsy. The results are not reliable. There is no anatomical-clinical relation in most cases. Differents pictures are observed: -- asymetrical ventricle enlargment, -- global ventricule enlargment, -- partial cerebral atrophy. III -- DISCUSSION 1. We are at the beginning of our study. 2. This not always possible to obtain a C.A.T. in emergency for a head injury, especialy at night. 3. Patients investigated following head trauma are among the most difficult to study with C.A.T. These invididuals send to be restless and uncooperative. Numerous artefacts produced by patient motion may lead to erroneous negative or positive diagnosis, so general anesthesia is often helpful. It is hoped that as a more rapid scanners become available this problem will be obviated. The C.A.T. alone is not capable, to provide all the necessary date concerning head injury. The C.A.T. is, however, re-adjusting our total investigation (E.E.G., angiograms) philosophy and practice rather than replacing the standard neuroradiological technique, except, may be, with epidural hematoma.

[Diagnostic criteria of depressive pseudodementia].

Ten patients fulfilling the DSM III (A, B, C, D) criteria for both dementia and major depression and presenting the diagnostic dilemma of depressive pseudodementia were included in a prospective study in search of indices for the differential diagnosis of depressive pseudodementia (DPSD) and organic dementia (OD). Patients were assessed with the Hamilton Depression Rating Scale (HDRS), the Blessed Dementia Rating Scale (BDRS), the Wells's criteria, the Mini Mental State (MMS), computerized tomography (CT scan) of the brain, the dexamethasone suppression test (DST), total plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) and sleep electroencephalograms (EEG). Patients suffering from DPSD were defined as showing an improvement higher than 50% in both the HDRS et BDRS scores following adequate antidepressant treatment. Wells's criteria, MMS scores, CT scan and DST do not contribute to the separation of DPSD (n = 6) and OD (n = 4). On the contrary, plasma MHPG levels higher than 35 ng/ml and EEG measures of sleep structure and REM sleep significantly differentiate the two groups.

Regional femur blood flow measurements with radiolabelled microspheres in fatty liver-induced or corticosteroid treated animals: preliminary report.

Using radio-labelled microspheres, the authors studied bone blood flows in various segments of goose femurs (femoral head, trochanter, condyles). Experiments were conducted on three groups of geese: control, fatty liver induced and corticosteroid-treated animals. The preliminary results suggest that hyperlipemia and fatty liver conditions do not seem to obviously disturb intra osseous blood circulation in fatty geese, although corticosteroids might affect bone blood flows in condyles.

[Electroclinical and CAT-encephalographic symptomatology of lipomas of the corpus callosum].

An analysis of four cases with lipomas of the corpus callosum with epilepsy and of some data in the literature has led to the following conclusions: 1) Epilepsy: a nearly constant feature is often severe always partial and begins before the age of fifteen; 2) Pathophysiology of the seizures: abandoning the classic theory that they depend upon an infiltration of the cingulate gyri by fibrous tissue growing out from the capsule of the lipoma, the authors consider that the essential mechanism is represented by the interhemispheric disconnection. This latter is responsible for a facilitory and disinhibitory action which would favour the appearance of seizures under the effects of an epileptogenic lesion, the effect of which would remain sub-threshold in the presence of an intact corpus callosum, playing its normal inhibitory role.
