    Notes: Summary Report of a series of 18 late secundary nerve grafts using lyophilised (disantigenised and disenzymatised) homografts of the Braun Melsungen Company. In contrast to the publication of Kuhlendahl et al. (1972) 32% of the cases showed definitive signs of regeneration. Therefore, in spite of the fact that autografts give better results, further research into the possibilities of homografts seems desirable. Their potential usefulness obviously is restricted to cases in which from any reasons autologous nerve grafts are not available.

    Description / Table of Contents: Zusammenfassung Die Ergebnisse der kombinierten elektro- und echoenzephalographischen Untersuchungen bei 321 Patienten mit Hirntumoren werden dargestellt. Bei 15 von 62 Tumoren der hinteren Schädelgrube und bei 8 von 26 Fällen mit Tumoren der Hypophysenregion ergaben beide Untersuchungsmethoden negative Ergebnisse. Bei 233 supratentoriellen Tumoren (die nicht im Hypophysenbereich lagen) waren mit Ausnahme von zwei Fällen alle EEG-Befunde pathologisch und 82% dieser Tumoren verursachten eine Verlagerung des Mittelechos. Als Kontrollversuch wurde eine Gruppe von 500 ambulanten Patienten untersucht. Von dieser Gruppe hatten 216 Patienten ein normales Elektro- und Echoenzephalogramm, obwohl sich herausstellte, daß ein parietales Meningeom bei diesen Fällen war.
    Abstract: Résumé On étudie l'E.E.G. et l'écho-encéphalographie chez 321 patients affectés de tumeur cérébrale. Sur 15 des 62 tumeurs de la fosse postérieure, et sur 8 des 26 cas de tumeurs de la région hypophysaire, les deux examens donnent des résultats négatifs. Sur 233 tumeurs supratentorielles (les tumeurs hypophysaires non inclues) tous les E.E.G. sauf deux, étaient anormaux, et 82% de ces tumeurs ont causé un déplacement des structures médianes dans l'écho-encéphalographie. Pour comparer 500 autres patients ont été étudiés. De ce groupe 216 avaient un E.E.G. et un écho encéphalographique normaux; bien qu'on ait trouvé un méningiome pariétal chez l'un d'entre eux.
    Notes: Summary The results of the combined electro- and echo-encephalographic examinations in 321 patients with a cerebral tumour are given. In 15 of 62 tumours in the posterior fossa and in 8 of 26 cases with tumour in the hypophysial region both examinations gave negative results. Of 233 supratentorial tumours (not in the hypophysial region) all but 2 E.E.G.'s were abnormal and 82% of these tumours caused a shift of the midline-echo. As a reliability test a group of 500 out-patients was screened. Of this group 216 patients had a normal E.E.G. and echo-encephalogram. Although a parietal meningioma was found to be present in one of them.

    Notes: Summary Among 2,600 patients, examined by computerized tomography, 404 had brain tumours, which were gliomas in 150 cases. There were 73 glioblastomas. Examination was performed according to Ambrose's method using an intravenous injection of 1 ml 60% contrast medium per kg body weight. Thus 98% of all gliomas could be demonstrated. Glioblastomas are shown in three different forms: an annular type (55%), a nodular type (18%), and a combined type (27%). Perifocal oedema is found in 88% of glioblastomas. The oedema most frequently belongs to grade II or III. Differential diagnosis of gliomas, abscess, metastases and other tumours with central necrosis are discussed.

    Description / Table of Contents: Summary A short review is presented of the spinal column changes which occur in achondroplastic dwarfs. The chief neurological results are, as a rule, due to compression of the spinal cord and/or of the cauda equina in the narrowed spinal canal. A personal case is described in whom the picture of intermittentpseudo-claudication was caused by an abnormal elongation of about 8 cm of the cauda equina roots. After decompressive operation the symptoms and signs regressed.
    Abstract: Résumé L'auteur présente une étude des modifications du rachis chez les nains achondroplastiques. Les signes neurologiques importants sont en règle liés à la compression de la moelle ou de la queue de cheval dans l'étroit canal spinal. Dans une observation personnelle, la pseudo claudication intermittente était liée à une élongation anormale de 8 cm des racines de la queue de cheval. Après une intervention décompressive les symptômes ont régressé.
    Notes: Zusammenfassung Es wird ein kurzer Überblick über die bei achondrodysplastischen Zwergen vorkommenden Wirbelsäulenveränderungen gegeben. Die häufig neurologischen Ausfälle beruhen in der Regel auf einer Kompression des Rückenmarkes und/oder der Cauda equina in dem verengten Wirbelkanal. Beschreibung eines eigenen Falles, bei dem das Bild einer Pseudo-Claudicatio intermittens durch eine abnorme Elongation der Kaudafasern um etwa 8 cm verursacht war. Nach operativer Dekompression bildeten sich die Störungen und Beschwerden zurück.

    Notes: Summary Results of measurementsin vivo of intracranial pressure obtained with a new telemetric epidural pressure transducer are described. The relations of epidural pressure to ventricular fluid pressure are studied in acute experiments and found to be linear, but variable. The functioning of 18 transducers was studied over many months of implantation.

    Notes: Objective A database with reference values of the durations of the various waveforms in a magnetocardiogram of fetuses in uncomplicated pregnancies is assessed. This database will be of help to discriminate between pathologic and healthy fetuses. A fetal magnetocardiogram is a recording of the magnetic field in a location near the maternal abdomen and reflects the electric activity within the fetal heart. It is a non-invasive method, which can be used with nearly 100% reliability from the 20th week of gestation onward.Design Durations of the waveforms were assembled from averaged magnetocardiograms and statistically processed.Setting Fetal magnetocardiograms were measured with different magnetocardiographs. All measurements were carried out in magnetically shielded rooms.Sample Fetal magnetocardiograms were obtained for 582 healthy patients.Method The durations of the waveforms were extracted from fetal magnetocardiograms measured at the cooperating centres. The variables collected included the duration of the P-wave, the PR interval, the PQ interval, the QRS complex, the QT interval and the T-wave and QTc value. The results were compared with values extracted from electrocardiograms of fetuses measured via electrodes attached to the maternal abdomen, from electrocardiograms measured during labour using a scalp electrode, and from electrocardiograms recorded in newborns, that were found in the literature.Main outcome measures Values of the durations are given as a function of gestational age including the regression line as well as the bounds marking the 90%, 95% and 98% prediction interval.Results The durations of the P-wave, the PR interval, the QRS complex, the QT interval and QTc value increase linearly with gestational age. The durations of the PQ interval and the T-wave are independent of fetal age.Conclusion The values found agree with those found in the literature. The scatter of the data is wide due to the variation in normal physiology, the measuring system and signal processing and the subjectivity of the researcher. However, the system can define normal ranges and may be used in diagnosis.
