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 ...

Methods Clinical and demographic data were extracted from the charts of 182 consecutive black Americans admitted for SICH diagnosed by clinical criteria and initial CT scan. Hemorrhage volumes were calculated from admission CT scans by a computerized method. Univariate and multiple logistic regression analyses were performed to determine independent predictors of early deterioration ...

Semantic Scholar extracted view of [Alterations of the cerebrospinal fluid during pneumoencephalography]. by Cecilia B Castells et al.

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. The important point is that there may be a huge difference when the patient is awake and when he/she is ...

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 ...

Observations related to the airways, respiration, circulation and consciousness are particularly important. Acting ahead, prevention, being prepared and call for ...

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 ...

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. ...

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 ...

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 ...

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 ...

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 ...

Computed tomography of 30 patients presenting acutely with benign intracranial hypertension was compared with that of 30 normal controls matched for age and sex. Qualitative and quantitative assessments showed smaller cranial CSF spaces in the cases of benign intracranial hypertension, suggesting that cerebral swelling is involved in the pathogenesis of benign intracranial hypertension.

TY - CHAP. T1 - Complications of ventriculo-peritoneal shunt. AU - Tseng, D. W.. AU - Liu, M. Y.. AU - Tsai, S. H.. PY - 1983. Y1 - 1983. N2 - The ventriculo-peritoneal shunt is a well established method in the treatment of primary and secondary hydrocephalus. 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. 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. It is postulated to have played a role in the

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 ...

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.. ...

Hydrocephalus is characterized by an abnormal increase in cerebrospinal fluid (CSF) volume within the intracranial cavity and by enlargement of the head in infancy. Pressure from increased fluid volume can damage the brain tissue. Hydrocephalus results from two major causes: obstruction of CSF flow (noncommunicating hydrocephalus) or faulty CSF absorption or overproduction of CSF (communicating hydrocephalus)..

With the advent of the aging society, dementia becomes the focus of common people. As for the neurodegeneration dementia, no disease modifying treatments have been discovered. Idiopathic normal pressure hydrocephalus (iNPH) is considered as one of reversible dementia, which can be hint by the surgery. In addition, dementia of iNPH is the typical subcortical dementia. Therefore exploring the pathogenic mechanism is conducive to the early diagnosis and treatment. This research is to monitor the changing of iNPHGS, cognitive function, walking ability as well as brain construction imaging and neural network before and after ventriculo-peritoneal shunting in order to demonstrate the pathogenesis of triads. In the process, the supplementary test, for instance, CSF tap test, will be validated the predictive value ...

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). Finally, we used data from a group of

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. ...

The ventricular spaces in the various subdivisions of the brain reflects the fact that the ventricles are the adult derivatives of the open space of the embryonic neural tube. The two lateral ventricles, situated within the cerebrum, are relatively large and C-shaped, and roughly wraps around the dorsal aspects of the basal ganglia. In the lateral ventricles of the embryo the successive generation of neurons gives rise to the 6-layered structure of the neocortex, constructed from the inside out during development. ...
