"Modem Neurosurgery of Meningiomas and Pituitary Adenomas" presents
the state-of-the-art of neurosurgery for these two types of tumors.
Following a classification of the pituitary adenomas according to
pathology, molecular biological factors are presented and their
effects evaluated as these aspects deepen our understanding of the
growth and further expansion of these tumors. The diagnosis is made
not only by a study of the hormonal status, but also by
neuroradiology. A number of authors have devoted their efforts to
the special problem groups such as the elderly patients and those
with huge pituitary adenomas. Particular emphasis is of course
placed on the surgical treatment, including transcranial and
transphenoidal neurosurgery, but the use of medical treatment and
irradiation must be discussed as well. The treatment of meningiomas
has also been influenced by the molecular biology of hormone and
growth factors. Therefore it is accorded extensive space in this
volume. The prognostic significance of nuclear DNA content is
discussed. Recent research with new diagnostic methods such as
somatostatin scintigraphy, PET studies end progesterone receptor in
tumor fragment spheroids is presented here. The treatment of these
tumors, however, depends largely on their localization. For the
neurosurgeon, the surgical treatment of meningiomas involving the
cavernous sinus, meningiomas of the ventral Foramen of Monroe,
meningiomas of the cerebello pontine angle and of the optic sheath
is presented by prominent experienced leaders in this field."
More than 40 years ago British and German neurosurgeons met in
Berlin and Breslau to exchange their experiences, to strengthen
their friendly bonds, and to enjoy the attractions of both cities
and their surroundings. In 1960 a joint meeting of the Dutch and
German societies took place in Rotterdam by invitation of the
Nederlandse Vereniging van Neurochirurgen. All who attended this
meeting thankfully remember the great hospitality during these
unforgettable days. In 1970, by courtesy of the Society of British
Neurological Surgeons, German neurosurgeons had the pleasure to
become acquainted with the great tradition of British sciences at
one of the most famous places during the meeting in Cambridge.
These impressions were deepened by visits to other famous sources
of British scientific tradition during the European Congress in
Oxford in 1975. The critical distance sometimes necessary towards
our own discipline is implicit in the major themes of this meeting.
Complications following shunting procedures for hydrocephalus have
been discussed on the basis of the results of a cooperative study
of some German neurosurgical departments. The second main topic was
problems and diagnostic errors in computer tomography. The papers
presented contain critical considerations about the findings
obtained by this method, as well as on its possibilities and
limitations. German neurosurgeons felt deeply indebted to their
British and Dutch colleagues and wanted to return their kindness at
this joint meeting in Berlin. We hope that all participants will
retain pleasant memories of the days in this city.
This volume of Advances in Neurosurgery 7 presents the papers held
at the Joint Meeting of the American Academy of Neurological
Surgery and the "Deutsche Gesellschaft fUr Neurochirurgie" in
October 1978 in Munich. This exchange of thoughts on scientific
methods in neurosurgery on both sides of the globe, i.e., both in
the United States and in Germany, covered a number of different
topics in the field of neurosurgery, with special emphasis on the
following subjects: Intracranial vascular surgery and specialized
neurosurgical techniques used for different operative approaches to
the skull, brain, pituitary gland, and peripheral nerves.
Contributions to the field of computer tomography, traumatology,
functional and experimental neurosurgey, as well as chemotherapy
rounded off the broad exchange of thoughts. In particular, the
variety of the problems discussed, gives insight into the present
state of our special field and shows progress and new points of
departure. Special gratitude is expressed to the Springer-\Tedag
for its help in editing the Ad vances in Neurosurgery, Volume 7.

The computer tomograms of the brain were investigated in 195
patients in whom a primary carcinoma was known to be present.
Metastases of bronchial and mammary carcinomas are most frequent.
It is not possible to achieve a definite differentiation of brain
metastases from known primary tumors. References 1. Kazner, E. ,

This volume of ADVANCES IN NEUROSURGERY presents the original texts
of 60 papers delivered at the 33rd annual meeting of the German
Neuro surgical Society held in Kiel from May 16th to 20th, 1982.
These papers represent a selection from some 162 papers submitted
and 96 actually given. The selection was made by the society's
programme committee, of which Professor W. J. BOCK, Professor H.
DIETZ and Professor W. GROTE are also members. I would like to take
this opportunity to express my sincere thanks to them for their
untiring cooperation. The scientific programme dealt with three
main themes: 1. Acute, non-traumatic intracranial hemorrhages, a
subject that has always been of importance for neurological
surgeons since the ana tomist Giovanni Battista MORGAGNI in 1791
first described in detail the clinical picture and the pathological
and anatomical causes of a brain hemorrhage he had observed in his
servant. Indeed, at our 31st annual meeting in Erlangen in 1980
"Timing Problems in Sub arachnoid Hemorrhages" was one of the main
topics of discussion. For this year's meeting a cooperative study
in which 27 university and hospital departments of neurosurgery
participated enabled us to look into the causes and the diagnostic
and therapeutic measures involved in a great number of cases of
intracranial hemorrhage."
W.DRIESEN This volume contains the original text of 60 papers
delivered at the 32nd Annual Meeting of the German Society for
Neurosurgery, held in TUbingen, 22nd to 25th April, 1981. They
represent a selection from 91 papers submitted, a third of which
had to be excluded on critical analysis. This was deemed necessary
on account of costs, and in order to keep the volume of a size and
standard usually achieved within the last few years. Three main
subjects were considered: 1. changes in methods of investigation
and treatment of neurosurgi cal.conditions, brought about by the
use of computerised axial tomography (C.A.T . scanning); 2. papers
dealing with fundamental research concerned with normal and
abnormal cerebral metabolism; 3. trauma to the vertebral column and
spinal cord, and its sequelae; and, 4. free communications. The
organisers of this meeting tried, in contradistinction to pre vious
custom, to shift the emphasis away from highlighting major
communications, and so to remain true to their intention to allow
experts in their fields to introduce their subjects and pin-point
problems, to which subsequent speakers could then address them
selves in detail in their own papers. In my view, this did occur in
a meaningful way, although not to perfection; a goal always
difficult to attain."
W. SCHIEFER The 31st annual meeting of the Deutsche Gesellschaft
fur Neurochirurgie was held in Erlangen on May 1 - 4,1980. The
numerous participants obviously enjoyed the opportunity to be co me
acquainted with the attractive city of gardens, lecture theatres
and workshops surrounded by a lovely countryside and a historic
environment. The pro gram included a visit to the neighboring city
of Nurnberg, to the old Reichsstadt Regensburg and an opening
ceremony in the orangerie of the Erlangen palace, where the
"Bamberger Ensemble fur alte Musik" presented interesting and
little-known early music. The annual meeting was held in the
newly-built "Kopfklinik" of the University of Erlangen-Nurnberg,
which houses the departments of neurosurgery, neurology and
ophthalmology. As far as possible, many functions of this hospital
were centralized because this has economic advantages and saves
personell. Other functional units, such as the operating theatres,
the intensive care units, research laboratories and units specific
to the individual disciplines remained decentralized and
independent. This concept has proved to be a happy solution. At the
membership meeting of the Deutsche Gesellschaft fur Neurochirurgie,
Prof. Dr. K. J. Zulch of Cologne was made an honorary member of
this society, of which he is a founding member."
Fifty-two patients operated on for this type of spondylogenic
myelo- pathy by the anterior approach were reexamined. The male:
female re- lation was 2 : 1. Fifty percent were males in the 5th
decade. About 20% had a congenital narrow spinal canal with an
ap-diameter below the minimal standard values (3). The maximum of
spondylogenic narrow- ing was found between C4 and C6 in 2/3 of the
cases. Results: good 44%, satisfactory 31%, unchanged 13%,
deteriorated 12%, mortality O. The duration of the neurological
symptoms before operation had no in- fluence on the surgical
results. Final neurological restitution was reached within 1 week
to 3 months after the operation. The operative results in patients
with congenital narrow spinal canal showed the same percentual
distribution as the results of the entire group. No factors could
be found to explain the groups of unsatisfactory results.

The 28th annual conference of the German Society for Neurosurgery
was held in Cologne, West Germany, from the 18th to the 21st of
September 1977. The conference dealt with problems concerning
craniocerebral injuries and space-occupying processes in the
posterior cranial fossa as well as general topics on clinical
practice and research with special attention paid to the work of
younger neurosurgeons. This volume is a presentation of the
conference results. Within the scope of the general topics, special
interest was directed toward the que stion of the current status of
cytostatic treatment for brain tumors. In addition to experimental
investigations, the results concerning cerebral tumors and
medulloblas tomas are reported. Cerebellar tumors represent two
further focal points: 1. From the diagnostic viewpoint, specific
results from computerized tomography are discussed, especially with
regard to the more extensive anatomic difficulties involved in the
posterior cranial fossa. 2. With emphasis on cerebellar processes,
the results of long-term measurements of intracranial pressure
during the postoperative follow-up period are reported."

The Neurosurgeons of Berlin are happy to welcome their colleagues
from Germany and from foreign countries to our Annual Meeting,
being held in this city once again after many years. The external
appearance of the city may have changed in many respects since our
winter meeting in 1965. This ist not the case, however, as concerns
the outstanding quality of its cultural life. We hope that you take
as much profit of it as possible. When choosing the scientific
themes of this congress, we were led by the idea that problems
should be discussed which are not dealt with at special symposia
this year. Thus, the problems related to lumbar disc surgery and
its complications were chosen as one main topic. This important
chapter of neurosurgery worries (and not seldom depresses) us in
our daily work. A joint statistic analysis has been made, for which
we are indebted to the colleagues from the following university
clinics: Essen, Freiburg, Graz, Hannover, Heidelberg, Kiel, Koln,
Mainz, Wiirzburg, Berlin-Charlottenburg, Berlin Steglitz, of the
Neurosurgical Department of the BG-U nfallklinik Frankfurt/Main, of
the Neurosurgical Department Wagner-J auregg-Krankenhaus Linz, of
the Neurosurgical Clinic of the Katharinen-Hospital Stuttgart, and
of the Neurosurgical Clinic of the Stadt. Krankenhaus Berlin-N
eukolln."
This volume contains the papers presented at the 26th Annual
Meeting of the Deutsche Gesellschaft fUr Neurochirurgie, held in
Heidelberg, Western Germany, on May 1-3,1975. Since at recent
meetings of the German Neurosurgical Society central
pathophysiological problems such as "central dysregulation" and
"brain edema" had been discussed extensively, it seemed appropriate
to choose another major area of cerebral patho- physiology for the
meeting in Heidelberg. CEREBRAL HYPOXIA is, as LANGFITT once
emphasized, "the final common denominator" of various cerebral
lesions with which the neurosurgeon is confronted every day. Raised
intracranial pressure, respiratory disorders and disturbances in
systemic arterial blood pressure, etc. may lead, if not treated, to
a focal or global lack of oxygen in the brain tissue. Anoxia
finally results in cell death and thus in irreversible cerebral
damage or even death. Main interest has therefore been focussed on
disturbances in cerebral perfusion pressure ("ischemic hypoxia")
and in arterial oxygenation ("hypoxic hypoxia"). The importance of
cerebral autoregulatory mechanisms protecting the brain against
tissue hypoxia, of patho- morphological alterations of the cerebral
vessels (e. g. the "no-reflow-phenomenon") in the course of severe
hypoxia, and of changes in brain metabolism have been discussed on
a large scale. The organizing committee was particularly happy to
have obtained internationally well-known scientists who presented
their work in the field of cerebral hypoxia.
On this occasion we look back on 25 years of the Deutsche
Gesellschaft fur Neuro chirurgie. They hold a great deal: founding
and development of the society, comple tion and extension,
communication between the individual members and contacts to other
societies beyond our borders. They also stand for close
co-operation with those who transfer their patients to u- the
neurologists and specialists in internal medicine, the
ophthalmologists and ear nose-and throat specialists as well as the
general surgeons. This 25th annual meeting will deal with two
examples of diseases that present common problems to the
neurologist and to the neurosurgeon, namely meningiomas and
multiple sclerosis. In view of their long histories often going
back over many years, both of these lesions lead to diagnostic
errors and indequate treatment. And yet it should be possible to
recognize meningiomas at an early date and to initiate the only
possible treatment, the operation, if all diagnostic measures are
repeatedly carried out. The diagnosis MS, on the other hand, with
the multiplicity of symptoms which are peculiar to this disease,
should continue to be re-examined until every other lesion has been
excluded with certainty. The increasing number of legal proceedings
because of diagnostic and therapeutic measures as well as the
doctor-patient talk preceding the written consent for these
measures are further problems in need of discussion. For this
reason, the topic "medical liability in special reference to the
neurosurgeon" was chosen for this meeting. Many questions
necessitate many answers."
This book examines how deterrence, coercion and modernization
theory has informed U.S. policy, addressing why former Defense
Secretary Robert McNamara's famous description of the Vietnam War
as the "social scientist's war" is so accurate. By tracing the
evolution of ties between social scientists and the government
beginning in World War I and continuing through the Second World
War and the early Cold War, the narrative highlights the role of
institutions like the RAND Corporation, the Social Science Research
Council and MIT's Center for International Studies that facilitate
these ties while providing a home for the development of theory.
The author compares and contrasts the ideas of Bernard Brodie,
Herman Kahn, Albert Wohlstetter, Thomas Schelling, Gabriel Almond,
Lucian Pye and Walt Rostow, among others, and offers a cautionary
tale concerning the difficulties and problems encountered when
applying social science theory to national security policy.

This 14th volume of Advanaes in Neurosurgery includes the papers
presented at the 36th Annual Meeting of the German Society of
Neurosurgery in Berlin, May 12-15, 1985. I would like to take this
opportunity to thank the members of the program committee of the
Society, Priv.-Doz. Dr. Klinger, Professors Brock, Dietz, Frowein,
Lausberg, Wlillenweber, and Dr. Reuter for their assistance in
selecting the contributions and in organizing the scientific
program. The first main topic of the meeting was Spinal Cord
Tumors. Introductory lectures dealing with basic anatomic
knowledge, neuropathological as pects, and neurologic problems were
followed by reports on examinations using conventional
neuroradiology, scintiscanning, computer tomography as well as the
most recent method in the diagnosis of spinal tumors, the magnetic
resonance tomography. Also presented were the results of a
multicentered study on spinal tumors, ascertained in cooperation
with 43 German and Austrian neurosurgical clinics. The participants
reported in great detail on the statistical data they recorded from
3056 cases and on the scientific findings obtained from this study.
The session concluded with lectures on the possibilities for
surgical treatment of spinal tumors and on oncologic and
radiotherapeutic mea sures. E: x: perimental Neurosurgery was the
second main topic. Leading authorities in the field presented
interesting papers on topics such as the therapy of vasculogenetic
brain edema, the determination of neurotransmitters in brain
tumors, results of cerebral blood flow measurement, and im proved
operative techniques using laser radiation."
