Cerebral Ventriculography
Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. It is used also for x-ray computed tomography of the cerebral ventricles.
Radionuclide Ventriculography
Imaging of a ventricle of the heart after the injection of a radioactive contrast medium. The technique is less invasive than cardiac catheterization and is used to assess ventricular function.
Ventriculography, First-Pass
Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over GATED BLOOD-POOL IMAGING for assessing right ventricular function.
Gated Blood-Pool Imaging
Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchronizer or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (VENTRICULOGRAPHY, FIRST-PASS).
Cerebral Arteries
The arterial blood vessels supplying the CEREBRUM.
Stroke Volume
The amount of BLOOD pumped out of the HEART per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume.
Angiocardiography
Radiography of the heart and great vessels after injection of a contrast medium.
Heart Ventricles
The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.
Cineangiography
Motion pictures of the passage of contrast medium through blood vessels.
Cerebral Infarction
The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).
Heart Aneurysm
A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
Sodium Pertechnetate Tc 99m
A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, cardiovascular and cerebral circulation, brain, thyroid, and joints.
Ventricular Function, Left
The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.
Cerebral Palsy
A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
Radionuclide Angiography
The measurement of visualization by radiation of any organ after a radionuclide has been injected into its blood supply. It is used to diagnose heart, liver, lung, and other diseases and to measure the function of those organs, except renography, for which RADIOISOTOPE RENOGRAPHY is available.
Cerebrovascular Circulation
The circulation of blood through the BLOOD VESSELS of the BRAIN.
Takotsubo Cardiomyopathy
A transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic (ECG) T wave inversions. This abnormality is associated with high levels of CATECHOLAMINES, either administered or endogenously secreted from a tumor or during extreme stress.
Ventricular Dysfunction, Left
A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
Middle Cerebral Artery
The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.
Technetium
The first artificially produced element and a radioactive fission product of URANIUM. Technetium has the atomic symbol Tc, atomic number 43, and atomic weight 98.91. All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is used diagnostically as a radioactive imaging agent. Technetium 99 which is a decay product of technetium 99m, has a half-life of 210,000 years.
Heart
The hollow, muscular organ that maintains the circulation of the blood.
Iothalamate Meglumine
A radiopaque medium used for urography, angiography, venography, and myelography. It is highly viscous and binds to plasma proteins.
Myocardial Infarction
NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).
Electrocardiography
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
Diatrizoate
A commonly used x-ray contrast medium. As DIATRIZOATE MEGLUMINE and as Diatrizoate sodium, it is used for gastrointestinal studies, angiography, and urography.
Prenalterol
A partial adrenergic agonist with functional beta 1-receptor specificity and inotropic effect. It is effective in the treatment of acute CARDIAC FAILURE, postmyocardial infarction low-output syndrome, SHOCK, and reducing ORTHOSTATIC HYPOTENSION in the SHY-RAGER SYNDROME.
Echocardiography
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
Technetium Tc 99m Pyrophosphate
A radionuclide imaging agent used primarily in scintigraphy or tomography of the heart to evaluate the extent of the necrotic myocardial process. It has also been used in noninvasive tests for the distribution of organ involvement in different types of amyloidosis and for the evaluation of muscle necrosis in the extremities.
Thallium
A heavy, bluish white metal, atomic number 81, atomic weight [204.382; 204.385], symbol Tl.

Radiography of the vascular system of the brain after injection of a contrast medium.
Infarction, Middle Cerebral Artery
NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.
Cardiac Volume
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
Iothalamic Acid
A contrast medium in diagnostic radiology with properties similar to those of diatrizoic acid. It is used primarily as its sodium and meglumine (IOTHALAMATE MEGLUMINE) salts.
Malaria, Cerebral
A condition characterized by somnolence or coma in the presence of an acute infection with PLASMODIUM FALCIPARUM (and rarely other Plasmodium species). Initial clinical manifestations include HEADACHES; SEIZURES; and alterations of mentation followed by a rapid progression to COMA. Pathologic features include cerebral capillaries filled with parasitized erythrocytes and multiple small foci of cortical and subcortical necrosis. (From Adams et al., Principles of Neurology, 6th ed, p136)
Coronary Disease
An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
Brain
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Tomography, Emission-Computed, Single-Photon
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
Cardiac Catheterization
Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.
Coronary Angiography
Radiography of the vascular system of the heart muscle after injection of a contrast medium.
Cerebral Veins
Veins draining the cerebrum.

Large empty sella with an intrasellar herniation of an elongated third ventricle. Case report. (1/112)

A 73-year-old female presented with a large empty sella with herniation of an elongated third ventricle concomitant with herniation of the surrounding subarachnoid space into the sella, manifesting as visual impairment and amenorrhea without galactorrhea. Magnetic resonance imaging and computed tomography cisternography clearly showed the large empty sella, without evidence of either hydrocephalus or benign intracranial hypertension, which is extremely rare.  (+info)

Midline cerebellar cystic schwannoma : a case report. (2/112)

An extremely unusual case of a cystic schwannoma in the region of the inferior vermis and posterior to the fourth ventricle in a fifteen year old boy is reported. The cystic tumour caused partial obstruction to the outflow of cerebrospinal fluid from fourth ventricle and resulted in development of supratentorial hydrocephalus. On investigations, the schwannoma simulated a Dandy-Walker cyst. The boy presented with symptoms of increased intracranial pressure. On surgery, the lesion was not arising from any cranial nerve, nor was it attached to brain parenchyma, blood vessel or to the dura. The possible histogenesis of the cystic schwannoma in a rare location is discussed.  (+info)

Initial loss of consciousness and risk of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage. (3/112)

BACKGROUND AND PURPOSE: Delayed cerebral ischemia (DCI) is a major cause of death and disability in patients with aneurysmal subarachnoid hemorrhage. We studied the prognostic value for DCI of 2 factors: the duration of unconsciousness after the hemorrhage and the presence of risk factors for atherosclerosis. METHODS: In 125 consecutive patients admitted within 4 days after hemorrhage, we assessed the presence and duration of unconsciousness after the hemorrhage, the neurological condition on admission, the amount of subarachnoid blood, the size of the ventricles, and a history of smoking, hypertension, stroke, or myocardial infarction. The relationship between these variables and the development of DCI was analyzed by means of the Cox proportional hazards model. RESULTS: The univariate hazard ratio (HR) for the development of DCI in patients who had lost consciousness for >1 hour was 6.0 (95% CI 3.0 to 12.0) compared with patients who had no loss or a <1-hour loss of consciousness. The presence of any risk factor for atherosclerosis yielded an HR of 1.4 (95% CI 0.6 to 3.5). The HR for unconsciousness remained essentially the same after adjustment for other risk factors for DCI. The HR for a poor World Federation of Neurological Surgeons score (grade IV or V) on admission was 2.9 (95% CI 1.5 to 5. 5); that for a large amount of subarachnoid blood on CT was 3.4 (95% CI 1.6 to 7.3). CONCLUSIONS: The duration of unconsciousness after subarachnoid hemorrhage is a strong predictor for the occurrence of DCI. This observation may contribute to a better understanding of the pathogenesis of DCI and increased attention for patients at risk.  (+info)

Prediction of effectiveness of shunting in patients with normal pressure hydrocephalus by cerebral blood flow measurement and computed tomography cisternography. (4/112)

Measurement of cerebral blood flow (CBF) and computed tomography (CT) cisternography were performed in 37 patients with a tentative diagnosis of normal pressure hydrocephalus (NPH) to predict their surgical outcome. The mean CBF of the whole brain was measured quantitatively by single photon emission computed tomography with technetium-99m-hexamethylpropylene amine oxime before surgery. The results of CT cisternography were classified into four patterns: type I, no ventricular stasis at 24 hours; type II, no ventricular stasis with delayed clearance of cerebral blush; type III, persistent ventricular stasis with prominent cerebral blush; type IV, persistent ventricular stasis with diminished cerebral blush and/or asymmetrical filling of the sylvian fissures. The mean CBF was significantly lower than that of age-matched controls (p < 0.005). Patients with a favorable outcome had a significantly higher mean CBF than patients with an unfavorable outcome (p < 0.005). Patients with the type I pattern did not respond to shunting. Some patients with type II and III patterns responded to shunting but improvement was unsatisfactory. Patients with type IV pattern responded well to shunting, and those with a mean CBF of 35 ml/100 g/min or over achieved a favorable outcome. The combination of CBF measurement and CT cisternography can improve the prediction of surgical outcome in patients with suspected NPH.  (+info)

Treatment of intraventricular hemorrhage with urokinase : effects on 30-Day survival. (5/112)

BACKGROUND AND PURPOSE: Intraventricular hemorrhage (IVH) remains associated with high morbidity and mortality. Therapy with external ventricular drainage alone has not modified outcome in these patients. METHODS: Twelve pilot IVH patients who required external ventricular drainage were prospectively treated with intraventricular urokinase followed by the randomized, double-blinded allocation of 8 patients to either treatment or placebo. Observed 30-day mortality was compared with predicted 30-day mortality obtained by use of a previously validated method. RESULTS: Twenty patients were enrolled; admission Glasgow Coma Scale score in 11 patients was +info)

The adult radiographic shuntogram. (6/112)

We describe the adult radiographic shuntogram, a simple method to evaluate the function and patency of a ventriculoperitoneal or ventriculoatrial shunt. The procedure involves placing contrast material into the valve of a shunt system and following the flow for appropriate clearing of contrast agent from the shunt tubing. Twenty-three studies were obtained in 15 patients in whom shunt malfunction was suspected. The method can be used to establish valve malfunction, ventricular or distal catheter obstruction, and peritoneal encystment.  (+info)

Radiological abnormalities in temporal lobe epilepsy with clinicopathological correlations. (7/112)

In 73 patients with drug-resistant temporal lobe epilepsy submitted to an unilateral anterior temporal lobectomy the radiographs were studied to see if there were any correlation with the pathology subsequently found and with the outcome of the operation. A small middle cranial fossa, focal calcification, and temporal horn displacement are often better indices of the underlying pathology than temporal horn dilatation alone. In a small number of cases, however, radiological changes were seen on the side opposite to an unilateral EEG focus, thus suggesting bilateral disease.  (+info)

Effect of intracranial pressure of meglumine iothalamate ventriculography. (8/112)

Intraventricular pressure was studied in 12 patients undergoing ventriculography with a water soluble positive contrast medium. Isovolumetric instillation of meglumine iothalamate into the lateral ventricles and the anterior part of the third ventricle caused only a small increase in ventricular fluid pressure (1.3 +/- 0.3 mmHg), but the pressure increased markedly (46.3 +/- 3.7 mmHg; P less than 0.001) when the contrast medium entered the posterior end of the third ventricle, aqueduct of Sylvius,, and fourth ventricle. This sharp increase in intracranial pressure could not be attributed solely to the postural changes or to alterations in arterial blood pressure. Possible mechanisms are discussed.  (+info)

Pneumoencephalography | Open Access articles | Open Access journals | Conference Proceedings | Editors | Authors | Reviewers |...
Pneumoencephalography makes use of plain X-ray images. Unfortunately, these are very poor at resolving soft tissues, such as the brain. Moreover, all the structures captured in the image are superimposed on top of each other, which makes it difficult to pick out individual items of interest (unlike modern scanners which are able to produce fine virtual slices of the body, including of soft tissues). Therefore, pneumoencephalography did not usually image abnormalities directly, rather their secondary effects. The overall structure of the brain contains crevices and cavities which are filled by the CSF. Unfortunately, both the brain and the CSF produce similar signals on an X-ray image. However, draining the CSF allows for greater contrast between the brain matter and the (now drained) crevices in and around it, which then show up as dark shadows on the X-ray image. The aim of pneumoencephalography is to outline these shadow-forming air-filled structures so that their shape and anatomical location ...

Concentrations of homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) were significantly higher in CSF obtained after injection of air during pneumoencephalography (PEG) than in lumbar CSF, as drawn before the injection. There was a high correlation between levels in the `mixed and lumbar samples of CSF in the case of each of the two acids. The concentration of lumbar HVA, but not that of 5-HIAA, was negatively correlated with CSF pressure. 5-HIAA levels were low in both samples of CSF in a group of epileptics, by comparison with controls. In two patients with Kufs disease and in one with Niemann-Pick disease, the concentration of HVA was very low in the lumbar sample. The application of a standardized PEG technique in the study of monoamine metabolism in man is suggested.. ...

Monitoring is probably the most important aspect of care of the patient with suspected OSA. Most recommend continuous pulse oximetry (rather than periodic assessment of O2 saturation) but our previous columns have highlighted the problems associated with just using pulse oximetry and the false sense of security that one may develop. Very important in that light is the work of Lynn and Curry (Lynn 2011) who describe 3 patterns of unexpected in-hospital deaths and demonstrate the problems with threshold-based alarms (almost all currently used alarm systems use threshold-based principles) in detecting early deterioration. Indeed, they posit that threshold-based alarms themselves often cause us to miss signs of early deterioration. The second pattern of deterioration they note is the classic CO2 narcosis but they note many of these cases are complicated by the third pattern typical of sleep apnea.

Psychosis - Doctors Lounge(TM)Psychosis - Doctors Lounge(TM)
The first brain image of person with psychosis was completed as far back as 1935 using a technique called pneumoencephalography1 (a painful and now obsolete procedure where cerebrospinal fluid is drained from around the brain and replaced with air to allow the structure of the brain to show up more clearly on an X-ray picture).. Pneumoencephalogram of person with psychosis, 1935Modern brain imaging studies, investigating both changes in brain structure and changes in brain function of people undergoing psychotic episodes have shown mixed results.. A 2003 study investigating structural changes in the brains of people with psychosis showed there was significant grey matter reduction in the cortex of people before and after they became psychotic2. Findings such as these have led to debate about whether psychosis is itself neurotoxic and whether potentially damaging changes to the brain are related to the length of psychotic episode. Recent research has suggested that this is not the case3 although ...

A computational fluid dynamics (CFD) model of the cerebrospinal fluid system was constructed based on a simplified geometry of the brain ventricles and their connecting pathways. The flow is driven by a prescribed sinusoidal motion of the third ventricle lateral walls, with all other boundaries being rigid. The pressure propagation between the third and lateral ventricles was examined and compared to data obtained from a similar geometry with a stenosed aqueduct. It could be shown that the pressure amplitude in the lateral ventricles increases in the presence of aqueduct stenosis. No difference in phase shift between the motion of the third ventricle walls and the pressure in the lateral ventricles because of the aqueduct stenosis could be observed. It is deduced that CFD can be used to analyze the pressure propagation and its phase shift relative to the ventricle wall motion. It is further deduced that only models that take into account the coupling between ventricles, which feature a ...

Background: The abdominal pannus is a well known medical condition of a large overhanging apron of skin and fat that extends well beyond the waistline. Technically the proper term is a panniculus but it is far more commonly referred to as a pannus. What defines a pannus is how large the actual overhang is.. There are five degrees of an abdominal pannus from a grade 1 that rests on the mons pubis to a grade 5 that hangs down to the knees. While no abdominal pannus is pleasant for the patient the grade 5 pannus is the most disabling. It not only obstructs the urinary stream and causes associated hygiene issues but its sheer weight makes mobility difficult. It causes tremendous strain on the back and knees and leads to early deterioration of both.. An abdominal panniculectomy procedure should not be confused with a more traditional tummy tuck. The scope of the problem being treated would indicate such but how the operation is performed and under what circumstance is also vastly different. This is ...

Novel Management of Ectopic Pregnancy in a Noncommunicating Rudimentary Horn of a Unicornuate Uterus | The Journal of the...
A 31-year-old gravida 3 para 1 woman with a history of a left unicornuate uterus with a noncommunicating rudimentary right horn came to our facility to establish care. At another facility approximately 2 to 3 weeks earlier, vaginal ultrasonography showed a 5-week intrauterine pregnancy in the left unicornuate uterus with a fetal pole. Findings on vaginal ultrasonography at the current visit were suspicious for an 8-week pregnancy in the right noncommunicating horn. This finding was confirmed by a maternal fetal medicine specialist. The patient was counseled regarding treatment options and the significantly higher risk of rupture of the rudimentary horn as the gestational age progressed. She was referred to Johns Hopkins Hospital for evaluation and management. ...

Cisternography and Ventriculography Gadopentate Dimeglumine-Enhanced MR Imaging in Pediatric Patients: Preliminary Report |...Cisternography and Ventriculography Gadopentate Dimeglumine-Enhanced MR Imaging in Pediatric Patients: Preliminary Report |...
BACKGROUND AND PURPOSE: Complex CSF diseases may be underdiagnosed or poorly understood on conventional CT or MR imaging. Although intrathecal CT cisternography with water-soluble iodinated contrast medium has been used, very few studies have dealt with the intrathecal use of gadopentate dimeglumine (Gd-DTPA), though it appears superior to CT. We report our experience with the intrathecal use of Gd-DTPA for MR cisternography and ventriculography in pediatric patients referred for study and treatment of complex CSF-related diseases.. MATERIALS AND METHODS: Ten patients (range, 1 month-16 years of age) were selected after we obtained specific informed consent. Intrathecal gadolinium injection was performed via transfontanelle ventriculostomy, ventriculoperitoneal shunt reservoir, or lumbar puncture. Cases included spontaneous CSF leaks (n = 1), complex traumatic frontoethmoidal fractures with suspected CSF leak (n = 2), multiloculated congenital or acquired hydrocephalus (n = 3), intraventricular ...

Psychosis - WikipediaPsychosis - Wikipedia
The first brain image of an individual with psychosis was completed as far back as 1935 using a technique called pneumoencephalography[81] (a painful and now obsolete procedure where cerebrospinal fluid is drained from around the brain and replaced with air to allow the structure of the brain to show up more clearly on an X-ray picture).. The purpose of the brain is to collect information from the body (pain, hunger, etc.), and from the outside world, interpret it to a coherent world view, and produce a meaningful response. The information from the senses enter the brain in the primary sensory areas. They process the information and send it to the secondary areas where the information is interpreted. Spontaneous activity in the primary sensory areas may produce hallucinations, which the secondary areas misinterpret as information from the real world.. For example, a PET or fMRI scan of a person who claims they hear voices may show activation in the primary auditory cortex, or parts of the brain ...

Anterior choroidal artery territory infarcts. Study of presumed mechanisms. | StrokeAnterior choroidal artery territory infarcts. Study of presumed mechanisms. | Stroke
A previous study suggested that occlusive diseases of small penetrating arteries account for most anterior choroidal artery (AChA) territory infarcts, but half of the patients did not have an echocardiogram. Cases of AChA territory infarcts associated with internal carotid artery stenosis or atrial fibrillation suggest that this hypothesis may be wrong. The aim of this study was to determine the mechanism of 16 nonselected consecutive AChA territory infarcts.. The study population consisted of 8 men and 8 women aged 17 to 89 years. They underwent a computed tomographic scan at the acute stage, Doppler ultrasonography and B-mode echotomography of the cervical arteries, bidimensional transthoracic echocardiography, and cerebral magnetic resonance imaging, replaced by a second computed tomographic scan in 3 patients. Ten patients underwent cerebral angiography. We defined the presumed cause of stroke according to the criteria used in the trial of Org 10172 in acute stroke treatment.. The presumed ...

Fatal Genes | by Andrew Solomon | The New York Review of BooksFatal Genes | by Andrew Solomon | The New York Review of Books
Later, when Tim, one of the Baxley boys, learns that his aunt has troubling symptoms, his heart began to pound as it had when he heard about his grandfather. Soon he felt the cold sweat of certainty…. He barely noticed the sun coming up. Robert Edwards, a progenitor of IVF, is flamboyant; so, a page later, is the Russian geneticist and embryologist Yury Verlinsky. Kolatas attempts to be colorful can drain her prose of authentic color.. The subtitle of the book is A Story of Hope, a Familys Genetic Destiny, and the Science That Rescued Them. Kolata tends to take an upbeat, even celebratory tone, but Amanda is looking at an early deterioration and horrific death, which doesnt exactly constitute a story of hope or a rescue by science. And what of Holly and her children, who may well be marching toward a similar agony? Kolata writes that science presented the Baxley family members with a responsibility theyd never asked for or anticipated-but that each took on in their own daring ...

Seventy ventriculo-peritoneal shunt operations were performed on fifty patients encountered at Tri-Service General Hospital during the last 7 years (1976-1982). The underlying causes of hydrocephalus were: brain tumor (25 cases), congenital hydrocephalus (16 cases), post-traumatic hydrocephalus (6 cases) and normal pressure hydrocephalus (3 cases). Twelve of the 50 patients (24%) developed post-operative complications. The complications in this series were: wound infection (5 cases), obstruction of the ventricular catheter (4 cases), disconnection of the reservoir connector (2 cases) and shortening of the peritoneal catheter (1 case). Among these 12 cases, 8 underwent two or more revisions of the shunt. The remaining 4 cases with ...

Final Diagnosis -- Case 797Final Diagnosis -- Case 797
FINAL DIAGNOSIS. Chordoid glioma of the third ventricle WHO 2007 grade II. DISCUSSION. Chordoid glioma is a rare tumor of the third ventricle, firstly proposed as a distinct entity by Brat et al in 1998 (1). To our knowledge (December, 2011), 74 cases (including our case) have been reported. The tumor predominantly occurs in adult women with a female to male ratio of 1.6 to 1 and the mean age at presentation at 45.25 years of age. Most patients have headache, visual symptoms, and memory disturbances. Other symptoms are lethargy, somnolence, endocrine disturbance such as hypothyroidism and diabetes insipidus, and symptoms caused by space occupying lesion and obstructive hydrocephalus are also observed in some patients. Chordoid glioma mainly locates at the third ventricle or nearby structures, hence the name Chordoid glioma of the third ventricle. Unusual locations without third ventricular association that have been reported are parieto-temporal region (3) and thalamic pulvinar area (5). The ...

White cerebellum sign a reversal of the normal gray/white matter densities and a relatively increased density of the thalami, brainstem and cerebellum; it is also known as dense cerebellum sign or reversal sign. On Computed Tomography, it is seen as hypodensity of the supratentorial brain with reverse increased attenuation of the cerebellum. This ominous sign is a poor prognostic indicator for patients with brain injury. We document a rare case of white cerebellum sign occurring in an eight year old girl who presented to the emergency department with signs of raised intracranial pressure following Ventriculo-peritoneal shunt revision. Our patient improved significantly after resuscitation with mannitol, she was discharged from hospital with an improved Glasgow Coma Score. Our case presents a new opportunity for management of patients with white cerebellar sign. Mannitol is an antioxidant that decrease H|sub|2|/sub|O|sub|2|/sub| by upregulating catalases.

Functional antagonism of alpha-subunits of Kv channel in developing brain ventricular system | DevelopmentFunctional antagonism of alpha-subunits of Kv channel in developing brain ventricular system | Development
The brain ventricular system is essential for neurogenesis and brain homeostasis. Its neuroepithelial lining effects these functions, but the underlying molecular pathways remain to be understood. We found that the K channels expressed in neuroepithelial cells determine formation of the ventricular system. The phenotype of a novel zebrafish mutant characterized by denudation of neuroepithelial lining of the ventricular system and hydrocephalus is mechanistically linked to Kcng4b, the homologue of the silent voltage-gated K channel alpha-subunit Kv6.4. We demonstrated that Kcng4b modulates proliferation of cells lining the ventricular system and maintains their integrity. The gain of Kcng4b function reduces brain ventricles. Electrophysiological studies supported an idea that Kcng4b mediates its effects via an antagonistic interaction with Kcnb1, the homologue of the electrically active delayed rectifier K channel subunit Kv2.1. The mutation of kcnb1 reduces the size of ventricular system and ...

JCI - Lipocalin 2 is essential for chronic kidney disease progression in mice and humansJCI - Lipocalin 2 is essential for chronic kidney disease progression in mice and humans
Mechanisms of progression of chronic kidney disease (CKD), a major health care burden, are poorly understood. EGFR stimulates CKD progression, but the molecular networks that mediate its biological effects remain unknown. We recently showed that the severity of renal lesions after nephron reduction varied substantially among mouse strains and required activation of EGFR. Here, we utilized two mouse strains that react differently to nephron reduction - FVB/N mice, which develop severe renal lesions, and B6D2F1 mice, which are resistant to early deterioration - coupled with genome-wide expression to elucidate the molecular nature of CKD progression. Our results showed that lipocalin 2 (Lcn2, also known as neutrophil gelatinase-associated lipocalin [NGAL]), the most highly upregulated gene in the FVB/N strain, was not simply a marker of renal lesions, but an active player in disease progression. In fact, the severity of renal lesions was dramatically reduced in Lcn2-/- mice. We discovered that Lcn2 ...

In our prospective study cohort, membranous obstruction was demonstrated in 92 (68.6%) of 134 cases of hydrocephalus with the use of 3D-CISS at 3T. Intraventricular membranous obstruction is the most common pathologic finding to cause noncommunicating hydrocephalus (85/114 total noncommunicating cases). However, except in the cerebral aqueduct region, conventional images are insensitive in detection of obstructive membranes in the CSF pathway. In this study, they were only demonstrated in 57 (36.3%) of 157 obstruction sites with the use of conventional imaging. In choosing the most appropriate treatment technique and to assess the prognosis in hydrocephalus, the classification of hydrocephalus and demonstration of obstruction, if it exists, are of significant importance.20,33 The terminology and the classification of hydrocephalus are still a matter of debate and are not the aims of our study. However, it is obvious that we need accurate neuroimaging techniques to demonstrate CSF pathways ...

During the last four years we have employed a ventriculo-peritoneal shunt with valve in 110 patients, including 79 hydrocephalic children. The results have shown that physically both the valve shunts draining into the peritoneum or into the blood stream work similarly. In both instances reoperations have not been frequent, as it was the case when no valves were used in the peritoneal shunts. On the other hand, by using ventriculo-peritoneal shunts not only pulmonary microembolism is prevented but also infections involving the draining system are less severe and more easily controlled than those occurring in the ventriculo-atrial shunts.. ...

Soon after Yaz was approved in 2006, it quickly become one of the most popular birth control pills of all time. The success rapidly faded after researchers found that drospirenone, the progestin in Yaz, was associated with up to a three-fold increased risk of blood clots compared to other progestins.. The problem with blood clots is that they can potentially travel to the brain and cause a stroke. In rare cases, blood clots in the brain can cause secondary intracranial hypertension. Similar to BIH, this condition causes high pressure inside the skull due to elevated levels of cerebrospinal fluid. Both conditions cause the same physical symptoms and can become chronic. ...

Post-traumatic hydrocephalus (PTH) is potentially under-diagnosed and under-treated, generating the need for a more efficient diagnostic tool. We aim to report CSF dynamics of patients with post-traumatic ventriculomegaly. We retrospectively analysed post-traumatic brain injury (TBI) patients with ventriculomegaly who had undergone a CSF infusion test. We calculated the resistance to CSF outflow (Rout), AMP (pulse amplitude of intracranial pressure, ICP), dAMP (AMPplateau-AMPbaseline) and compensatory reserve index correlation coefficient between ICP and AMP (RAP). To avoid confounding factors, included patients had to be non-decompressed or with cranioplasty | 1 month previously and Rout | 6 mmHg/min/ml. Compliance was assessed using the elasticity coefficient. We also compared infusion-tested TBI patients selected for shunting versus those not selected for shunting (consultant decision based on clinical and radiological assessment and the infusion results).

The objective of this work is to quantify age-related differences in the characteristics and coupling of cerebral arterial inflow and cerebrospinal fluid (CSF) dynamics. To this end, 3T phase-contrast magnetic resonance imaging blood and CSF flow data of eleven young (24 ± 3 years) and eleven elderly subjects (70 ± 5 years) with a comparable sex-ratio were acquired. Flow waveforms and their frequency composition, transfer functions from blood to CSF flows and cross-correlations were analyzed. The magnitudes of the frequency components of CSF flow in the aqueduct differ significantly between the two age groups, as do the frequency components of the cervical spinal CSF and the arterial flows. The males aqueductal CSF stroke volumes and average flow rates are significantly higher than those of the females. Transfer functions and cross-correlations between arterial blood and CSF flow reveal significant age-dependence of phase-shift between these, as do the waveforms of arterial blood, as well as ...

Ventriculo-peritoneal shunting is a surgical treatment for hydrocephalus. Complications of this procedure are not well described in dogs. The most common complication in humans is infection, which can be fatal if not diagnosed and treated quickly. We describe the magnetic resonance (MR) imaging characteristics of a shunt-associated cerebral infection in a dog. The MR features of the infection included hyperintensity of the lining of the ventricular system visible on a T2-weighted FLAIR sequence and marked linear contrast enhancement of the ependymal layer on T1-weighted sequences, similar to that described in people. ...

  • Angiocardiography (left ventriculography and selective coronary arteriography), peripheral arteriography, visceral arteriography, and cerebral arteriography (320 mg Iodine/mL). (nih.gov)
Ventricles4
  • Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. (nih.gov)
  • It is used also for x-ray computed tomography of the cerebral ventricles. (nih.gov)
  • Ventriculography showed dilatation of lateral ventricles in all patients who were subjected to the examination. (ac.ke)
  • Compared with CT scanning, MRI offers a better ability to detect cerebritis, greater contrast between cerebral edema and the brain, better visualization of the brainstem, and earlier detection of satellite lesions and the spread of inflammation into the ventricles and subarachnoid space.

Contrast3
  • Magnetic resonance ventriculography and cine phase-contrast magnetic resonance imaging can determine stoma patency. (nih.gov)
  • Contrast enhancement with gadolinium diethylenetriaminepentaacetic acid (a paramagnetic agent) helps differentiate the abscess, the enhancement ring, and the cerebral edema around the abscess. (medscape.com)
  • ventriculography with water-soluble contrast media. (liverpool.ac.uk)
Magnetic1
  • Any other reliable cardiac imaging test, such as cardiac magnetic resonance imaging (cardiac MRI) or ventriculography performed during cardiac catheterization, can also satisfy the LVIDD measurement. (dothanalabamadisabilitylawyers.com)
Procedure1
  • Of the 101 AS patients who had retrograde catheterization of the aortic valve, 22% manifested new focal diffusion abnormalities consistent with acute cerebral embolic events after the procedure, but only three of these patients (3%) had clinically apparent neurologic deficits. (medscape.com)
Patients2
  • Lesse and Netsky 8 concluded from their autopsy material of 595 cancer patients t h a t lung cancer metastasized to the central nervous system with great frequency, giving rise to cerebral implants in 50 per cent of the cases. (booksc.org)
  • There is general agreement on the bleak outlook of patients with pulmonary and cerebral lesions. (booksc.org)
