    Notes: Summary This paper is based on a study of sixty cases of cranio-cerebral erosion treated in the Department of Neurosurgery. All India Institute of Medical Sciences, New Delhi during the last 20 years. This constitutes the largest series, so far reported from anywhere. It has provided a unique opportunity to get a comprehensive picture of the clinical and radiological features of this lesion, as also their evolution. These have been correlated with the findings at surgery and histopathological observations. The study highlights the incidence, pattern and severity of the brain damage associated with this lesion. Evidence has been provided for the progressive nature of the brain damage, not adequately emphasized in the existing literature. Pathogenesis of this brain damage has been discussed. The role of surgery in the management of this lesion has been outlined. Emphasis on the osseous changes or the “leptomeningeal cyst” (not really a consistent or important feature) in most publications on this subject has tended to minimize the significance of the brain damage in this condition. The authors suggest that the latter is far more important and therefore, recommend the use of nomenclature which takes this into account.

    ISSN: 0942-0940

    Notes: Summary The clinical features and management of 18 patients with congenital heart disease and a brain abscess are reviewed. Except for one patient all had cyanosis. All abscesses were large, containing at least 50–60 ml of pus, and mostly unilocular. Bilocular and multilocular abscesses were also encountered. The organisms cultured from the pus had little relation to the mortality. Tapping may be the final investigation, and is also the treatment of choice. The high mortality (50%) is attributed to the delay in referral of these patients to a neurosurgical unit.

    Notes: Summary In cases of closed head injury temporal lobe lesionse.g. contusion, laceration, pulping, or intracerebral haematoma frequently result in an expanding process. These are frequently associated with an overlying subdural haematoma. Eighty five cases of such lesions from a consecutive series of 1,000 cases of head injury have been analyzed. The lesions are caused by severe injury resulting in loss of concsiousness and skull fracture. Most of them are contre-coup lesions. Clinically they manifest themselves like any other acute or subacute intracranial hematoma. The majority of the patients have contralateral hemiparesis and pupillary abnormalities. Carotid angiography is valuable for diagnosis. These lesions are likely to be missed when exploratory burr holes are made or, are erroneously diagnosed as acute subdural haematoma or brain oedema. Smaller lesions, not showing progressive deterioration, may respond to conservative treatment. However, surgical decompression is essential in most cases. A fronto-temporal osteoplastic craniotomy or a large Scoville trephine hole is essential to deal with these lesions adequately.

    Notes: Summary Seventeen cases of cranio-cerebral erosion were subjected to detailed histopathological study in order to get a better insight into the pathogenesis of this lesion. It was found that the bone and brain at the site and edge of the defect show not only evidence of damage at the time of initial injury, but also of “active” progressive damage months and years later. The possible causes for continuing damage to the brain and bone are discussed.

    Brainstem auditory evoked response and vestibulo-ocular reflex in severe head injury patients (1987)
    Springer
    Acta neurochirurgica 87 (1987), S. 40-43 
    Details
    ISSN: 0942-0940
    Keywords: Severe head injury ; brainstem auditory evoked response ; cold caloric response ; outcome
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Brainstem auditory evoked response (BAER) performed in 60 serious head injury patients, over the last two year period at All India Institute of Medical Sciences, New Delhi have been analysed, to correlate the findings with ultimate outcome. All patients included in this study were unconscious, not following any command at the time of initial evaluation, mostly within 48 hours of injury. Repeat studies were performed in surviving patients. Computerized cranial tomography was performed to establish the nature of the intracranial pathology. The clinical status and cold caloric responses were recorded in all. The patients were followed up for 1 to 24 months. Three patients had extradural haematoma, 2 patients had subdural haematoma and 30 patients had intracerebral contusion/haematoma. Brain oedema was recorded in 14 cases. BAER was normal in 32 patients and 26 of them had good recovery (81%). Three patients with normal BAER died. Abnormal BAER was recorded in 21 patients and only 50% of them had good recovery and 25% of them died. In 7 patients BAER was absent and only 2 (29%) had a good recovery. Thus 48 out of 60 patients (66%) had a good recovery and 11 (18%) died. When compared to cold caloric response, 87% patients with normal caloric response had a good recovery and 5 out of 6 patients with absent caloric response died and remaining 1 left in a vegetative state. Thus the caloric response is at least as good a prognostic factor as BAER.

    Notes: Summary Eight children with post-traumatic pseudomeningocele are reported. In this paper the mean age at the time of injury was one year and ten months. All of them gave a history of a fall from a height. In six patients the meningocele was located in the parietooccipital region. The frontal bone was involved in one and the roof of the orbit in another. All these patients had localized progressive swelling of the skull associated with a bony defect. Four patients had a history of convulsion and three had hemiparesis. The meningocele was excised, the dural defect repaired and a cranioplasty was performed in all. Good recovery was observed in all of them.

    Mössbauer and magnetization studies in Fe3−xRuxSi (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 3258-3260

    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Magnetization and 57Fe Mössbauer studies have been made in Fe3−xRuxSi for 0≤x≤2. Up to x=1.35, the alloys behave like collinear ferromagnets and μ/f.u. and HF (Fe) values do not show any appreciable change, thus suggesting that Ru replacing magnetic Fe (A,C) atoms also possess a large moment of ∼1 μB. For x〉1.35, the approach of magnetization to saturation becomes progressively slower and the system acquires an inhomogeneous magnetic structure. In the region 1.45 ≤x〈1.8, Tm and Thf, the HF (Fe) evolution temperature, fall rapidly, with Thf(very-much-less-than)Tm resulting in a behavior a la RuFeSi. For x〉1.8, majority of the Fe atoms are on B site and they presumably undergo AF/random freezing. Even though Tm and magnetization behavior show considerable variation across the region 1≤x≤2, the character of Mössbauer spectra does not change and 〈HF (Fe)〉av measured at 4.2 K remain ∼250 kOe.

    Description / Table of Contents: Résumé Les auteurs ont étudié 60 cas de cisternographies à la RISA avec/ou ventriculographies chez des enfants âgés de un mois à 15 ans, atteints de différents troubles de la circulation du LCR. Cette étude comprenait des cas d'hydrocéphalie et d'autres malformations congénitales du système nerveux central ainsi que des séquelles post-traumatiques et post-méningitiques. L'examen se révéla fiable, non seulement dans la différenciation entre hydrocéphalie compensée ou progressive mais également dans la détection d'anomalies associées de la circulation de LCR en cas de méningo-myélocèles d'encéphalocèles. Cette technique est excellente pour la localisation d'une fistule de LCR; elle peut également visualiser la taille et l'extension d'un hématome sous-dural ou d'un hydrome. La concentration pathologique et l'élimination tardive du radio-élément dans la région sous-jacente à la lacune crânienne étaient constantes dans tous les cas de lacunes post-traumatiques. Des blocages uniques ou multiples furent observés dans des cas de séquelles postméningitiques (tuberculose).
    Abstract: Zusammenfassung Bei 60 Kindern im Alter swischen 1 Monat und 15 Jahren wurde die RIHSA-Cisternographie und/oder Ventrikulographie durchgeführt. Es sollten damit unterschiedliche Hydrocephalus-Formen und andere angeborene Mißbildungen des Zentralnervensystems, auch posttraumatische und postmeningitische Veränderungen nachgewiesen werden. Diese Untersuchungsmethode zeigt sich besonders wertvoll zur Differenzierung der einzelnen Hydrocephalus-Arten zum Nachweis von Anomalien der Liquorzirkulation, besonders bei Meningomyelozelen und Encephalozelen. Auch können Liquorfisteln und subdurale Hämatome oder Hygrome damit exakt festgestellt werden. Pathologische Veränderungen finden sich auch bei allen Patienten mit wachsenden Frakturen. Bei postmeningitischen (tuberkulösen) Verklebungen konnte der Stopp lokalisiert werden.
    Notes: Summary Sixty children aged between one month and fifteen years were submitted to RIHSA cisternography and/or ventriculography for a variety of lesions affecting the CSF pathways. These included cases of hydrocephalus and other congenital malformations of the central nervous system, posttraumatic and post meningitic sequelae. The investigation has been found to be valuable not only in differentiating between arrested and progressive hydrocephalus but also in unmasking associated anomalies of CSF flow and pathways in cases of meningomyelocele and encephalocele. It is excellent for delineating a CSF fistula and can also be utilised to demonstrate the size and extent of a subdural hematoma or hygroma. Pathological concentration and delayed clearance of the isotope in the region underlying the skull defect was a consistent finding in all cases of growing fracture (craniocerebral erosion). Single or multiple sites of blocks were observed in cases of postmeningitic (tuberculous) sequelae.
