Not A Brain Tumor: Serious Headaches Explained Spanish researchers identified enlarged pituitary glands in the brains of 11 patients with headache symptoms characterized as intracranial hypotension syndrome http://www.eurekalert.org/pub_releases/2000-12/AAoN-Nabt-2512100.php
Extractions: American Academy of Neurology ST. PAUL, MN Headaches that may at first seem to be caused by a brain tumor can actually stem from a leak of spinal cord fluid, according to a study in the December 25 issue of Neurology, the scientific journal of the American Academy of Neurology. Spanish researchers identified enlarged pituitary glands in the brains of 11 patients with headache symptoms characterized as intracranial hypotension syndrome. People suffering from this syndrome experience headaches that occur or worsen shortly after sitting up from a lying position. "This is a disorder that was recently believed to be rare. New imaging technology has told us quite the opposite," said Jerome Posner, MD, Memorial Sloan-Kettering Cancer Center neurologist and co-author of an editorial accompanying the study. "The incapacitating headaches experienced by sufferers of this disorder can now be explained and treated, and not confused for a brain tumor." Primarily diagnosed by a low spinal cord fluid pressure reading, the intracranial hypotension experienced by study participants had varied causes including spontaneous occurrence, unexplained fluid loss, lumbar puncture (spinal tap) and cervical spine surgery. Neck pain, nausea, hearing and vision problems and facial numbness accompanied the headaches.

Extractions: DISCUSSION It is well known that headaches are one of the most common symptoms in patients with IH syndrome. The site of the headaches may be at the frontal, vertex, occipital regions, or the whole head. The characteristics are often varied, either throbbing or tension in nature, and are usually not relieved by analgesics alone.(5) Importantly, the head pain also varies in intensity, with associated clinical presentations such as dizziness, nausea, vomiting, and tinnitus.(8) Our patient presented with throbbing pain at the vertex in association with neck tightness, dizziness, nausea, and vomiting. In addition, her headaches were relieved quickly on recumbence. Therefore, a detailed search of causes underlying orthostatic headaches is warranted.
The World Arnold Chiari Malformation Association 242 Acquired Chiari I malformation secondary to spontaneous spinal cerebrospinal fluid leakage and chronic intracranial hypotension syndrome in seven cases. http://www.pressenter.com/~wacma/acquired.htm
Extractions: Department of Neurosurgery, Kyushu University, Fukuoka, Japan. The authors report a case of bilateral chronic subdural hematoma in a 25-year-old woman who had occipital and neck pain. Magnetic resonance imaging revealed progressive caudal descent of the cerebellar tonsils (acquired Chiari I malformation) and a large eccentric syrinx in the spinal cord from the C3-T7 levels. Spontaneous disappearance of the chronic subdural hematomas resulted in radiographic resolution of both lesions, as well as clinical improvement. Theories of syringomyelia formation, the relationship to acquired Chiari I malformation, and the implications of this case are discussed. 2. J Neurosurg 1998 Feb;88(2):237-242

Extractions: Rashna S Dastur, Daya K Manghani Muscular dystrophy covers a diverse group of inherited disorders in which the main clinical defects in the skeletal muscle i.e. weakness and wasting are mainly similar in all patients, but show genetically different diseases. This suggests that the various gene products participate or work together as a common functional structure or "biochemical cascade". In striated muscle cells, dystrophin - glycoprotein complex (DGC) serves as a link between the extracellular matrix and the subsarcolemmal cytoskeleton. The absence or dysfunction of one gene product (protein) in the DGC affects the functioning of the others causing the muscle cell to breakdown. Variability of clinical severity and the age of onset found in different types of dystrophies therefore depend on the functional importance of their gene products to the complex. Cohens technique for reimplantation was used in 40 patients (73 ureters), Leadbetter-Politano Technique in 31 patients (41 ureters), Lich-Gregoir Technique in 11 patients (15 ureters), and Paquins Technique in 9 patients (11 ureters). Ureteric tailoring was performed in 27 ureters while ureteric plication was done in 11 ureters. Ureteric stents were placed post-operatively in 94 ureters.
Extractions: The common presenting feature of BIH is headache. The signs are papilloedema and sometimes sixth nerve palsy. Raised intracranial pressure confirms the diagnosis. If associated with a medicine, the condition may resolve totally on stopping it. Treatment includes therapeutic lumbar punctures and acetazolamide. Complications of BIH can be lasting visual defects or even blindness, so discontinue the medicine and refer promptly if suspected. References Case report: BIH recurred on rechallenge with minocycline BIH is associated with various medical conditions and medicines Benign intracranial hypertension (also known as pseudotumor cerebri, or idiopathic intracranial hypertension) is a rare condition of unknown cause with an annual incidence of 0.9/100,000 in the general population. It is likely that there is a genetic predisposition.

Extractions: Causes, incidence, and risk factors: The dura is the membrane that surrounds the brain and spinal cord and contains the cerebrospinal fluid (CSF). A tear in the dura may occur under the following circumstances: after penetrating head trauma. CSF leak can also be caused by a lumbar puncture (spinal tap) or by epidural placement of catheters for anesthesia or pain medications.

Extractions: Department of Neurology, University of California, School of Medicine, San Francisco 94143. We report two patients with spontaneous intracranial hypotension. In addition to the cardinal features of a postural headache and a low CSF pressure, the patients also had subdural fluid collections demonstrated by head MRI. In both patients, radionuclide cisternography revealed a CSF leak along the spinal axis and rapid accumulation of radioisotope in the bladder. CSF leakage from spinal meningeal defects may be the most common

Extractions: L'évolution de la maladie se fait quelques années plus tard vers des troubles articulaires et tendineux associés à des problèmes de marche, avec tremblements, rigidité dans les mouvements, ainsi que des troubles de la parole. La maladie de Shy et Drager, qui évolue vers la mort après une période très longue, est secondaire à une atteinte anatomique à type de dégénérescence (destruction progressive) des noyaux gris du cerveau (amas de substance grise noyés dans la substance blanche) mais également des noyaux gris situés dans la moelle épinière et à d'autres niveau de l'encéphale (système nerveux à l'intérieur du crâne). Ces noyaux gris portent le nom de locus niger, noyau dorsal du vague, locus caeruleus, putamen. Ces localisations nerveuses permettent, quand leur état est normal, d'assurer le bon fonctionnement automatique de certains organes (régulation de la tension artérielle, régulation de la sueur, adaptation de l'ouverture et de la fermeture des vaisseaux, etc ). · L'hypotension contrôlée (en anglais induced hypotension) se caractérise par l'abaissement de la tension artérielle au cours de certaines interventions chirurgicales nécessitant une diminution de la pression du sang à l'intérieur des vaisseaux. C'est le cas, entre autres, des interventions portant sur les lésions de la face et de la mâchoire (chirurgie maxillo-faciale) ou des tumeurs vasculaires (touchant les vaisseaux) situées dans l'encéphale (à l'intérieur du crâne). L'hypotension contrôlée est mise en place pour éviter les hémorragies susceptibles d'avoir lieu au cours de l'intervention.
