    BACKGROUND: Use of antiplatelet therapy shortly before stroke due to spontaneous primary intracerebral haemorrhage (ICH) is associated with higher case fatality in comparison to ICH without prior antithrombotic drug use. The PlAtelet Transfusion in Cerebral Haemorrhage (PATCH) trial aimed to assess the effect of platelet transfusion in patients presenting with ICH while using antiplatelet therapy. The main hypothesis of PATCH was that platelet transfusion would reduce death or dependence by r...

    Full Text Available Abstract Background Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect. Methods/Design The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included. Discussion To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.

    Full Text Available Introduction. Reversible cerebral vasoconstriction syndrome is becoming widely accepted as a rare cause of both ischemic and haemorrhagic stroke and should be evocated in case of thunderclap headaches associated with stroke. We present the case of a patient with ischemic stroke associated with cortical subarachnoid haemorrhage (cSAH and reversible diffuse arteries narrowing, leading to the diagnosis of reversible vasoconstriction syndrome. Case Report. A 48-year-old woman came to the emergency department because of an unusual thunderclap headache. The computed tomography of the brain completed by CT-angiography was unremarkable. Eleven days later, she was readmitted because of a left hemianopsia. One day after her admission, she developed a sudden left hemiparesis. The brain MRI showed ischemic lesions in the right frontal and occipital lobe and diffuse cSAH. The angiography showed vasoconstriction of the right anterior cerebral artery and stenosis of both middle cerebral arteries. Nimodipine treatment was initiated and vasoconstriction completely regressed on day 16 after the first headache. Conclusion. Our case shows a severe reversible cerebral vasoconstriction syndrome where both haemorrhagic and ischemic complications were present at the same time. The history we reported shows that reversible cerebral vasoconstriction syndrome is still underrecognized, in particular in general emergency departments.

    Full Text Available Abstract Background Within the spectrum of spontaneous intracerebral haemorrhage there are some patients with large or space occupying haemorrhage who require surgery for neurological deterioration and others with small haematomas who should be managed conservatively. There is equipoise about the management of patients between these two extremes. In particular there is some evidence that patients with lobar haematomas and no intraventricular haemorrhage might benefit from haematoma evacuation. The STICH II study will establish whether a policy of earlier surgical evacuation of the haematoma in selected patients will improve outcome compared to a policy of initial conservative treatment. Methods/Design an international multicentre randomised parallel group trial. Only patients for whom the treating neurosurgeon is in equipoise about the benefits of early craniotomy compared to initial conservative treatment are eligible. All patients must have a CT scan confirming spontaneous lobar intracerebral haemorrhage (≤1 cm from the cortex surface of the brain and 10-100 ml in volume. Any clotting or coagulation problems must be corrected and randomisation must take place within 48 hours of ictus. With 600 patients, the study will be able to demonstrate a 12% benefit from surgery (2p Stratified randomisation is undertaken using a central 24 hour randomisation service accessed by telephone or web. Patients randomised to early surgery should have the operation within 12 hours. Information about the status (Glasgow Coma Score and focal signs of all patients through the first five days of their trial progress is also collected in addition to another CT scan at about five days (+/- 2 days. Outcome is measured at six months via a postal questionnaire to the patient. Primary outcome is death or severe disability defined using a prognosis based 8 point Glasgow Outcome Scale.

    2015-11-01

    Full Text Available Delayed cerebral ischaemia has been described as the single most important cause of morbidity and mortality in patients who survive the initial aneurysmal subarachnoid haemorrhage. Our understanding of the pathophysiology of delayed cerebral ischaemia is meagre at best and the calcium channel blocker nimodipine remains the only intervention to consistently improve functional outcome after aneurysmal subarachnoid haemorrhage. There is substantial evidence to support cerebral vessel narrowing as a causative factor in delayed cerebral ischaemia, but contemporary research demonstrating improvements in vessel narrowing has failed to show improved functional outcomes. This has encouraged researchers to investigate other potential causes of delayed cerebral ischaemia, such as early brain injury, microthrombosis, and cortical spreading depolarisation. Adherence to a common definition of delayed cerebral ischaemia is needed in order to allow easier assessment of studies using multiple different terms. Furthermore, improved recognition of delayed cerebral ischaemia would not only allow for faster treatment but also better assessment of interventions. Finally, understanding nimodipine’s mechanism of action may allow us to develop similar agents with improved efficacy.

    Cerebral vasospasm (CV) is one of the most dreaded complications in patients who survive acute subarachnoid haemorrhage (SAH), and conventional cerebral angiography (DSA) is the gold standard for its diagnosis. We evaluated CT angiography (CTA) as a non-invasive alternative for diagnosis of CV and assessed if CTA could have a role in choosing appropriate treatment. Consecutive patients with SAH and suspected vasospasm were included when DSA was performed within 24 h from CTA. Two neuro-radiologists retrospectively analysed CTA and DSA studies independently. Assessment included presence of central and peripheral vasospasm and grading of severity of central CV. A treatment recommendation based on CTA was compared to actual treatment received. Final analysis included 34 patients. CTA was more accurate for diagnosis of central then for peripheral CV with high sensitivity (reader 1, 91%; reader 2, 92%), specificity (reader 1, 73%; reader 2, 90%), accuracy, positive predictive value and negative predictive value for central vasospasm. For grading the severity of CV CTA's sensitivity, specificity and accuracy were high for most central arteries. The reader's recommendation of angioplasty according to CTA was significantly predictive of actual receipt of angioplasty but overestimated actual receipt of triple H treatment. CTA is adequate for detecting central vasospasm in symptomatic SAH patients. A negative result should not prevent further investigation especially when evaluating arterial segments adjacent to metal artefacts from coils or clips. CTA is helpful in treatment decision making specifically regarding the need for balloon angioplasty. (orig.)

    Cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) may be reduced in patients with normal pressure hydrocephalus (NPH) after subarachnoid haemorrhage (SAH). However, little is known about brain circulation in asymptomatic patients with ventriculomegaly after SAH. This study investigated CBF and CVR in symptomatic and asymptomatic patients with ventriculomegaly to clarify the mechanism of NPH. CBF and CVR were investigated in 48 patients with ventriculomegaly after SAH due to ruptured aneurysm. Mean CBF of the whole brain was measured by first-pass radionuclide angiography using technetium-99m hexamethylpropylene amine oxime. CVR was measured as the percentage change from the baseline mean CBF value after administration of 500 mg acetazolamide. Thirty patients with NPH who responded to shunting had significantly (P<0.01) reduced mean CBF and CVR compared with normal controls. Fourteen asymptomatic patients with ventriculomegaly showed significant (P<0.01) reduction in CVR but no difference in mean CBF. Four symptomatic patients who did not respond to shunting showed significantly (P<0.01) reduced mean CBF but had preserved CVR. Postoperative mean CBF and CVR increased significantly (P<0.01) in 21 patients who responded to shunting, but showed no significant change in four symptomatic patients who did not respond to shunting. Reduction of CBF superimposed on pre-existing impairment of CVR may be an essential step in the mechanism responsible for the manifestation of symptoms of NPH. (orig.)

    Full Text Available Abstract Background Postpartum haemorrhage remains an important cause of maternal death despite treatment with conventional therapy. Uncontrolled studies and one randomised comparison with conventional oxytocics have reported dramatic effects with high-dose misoprostol, usually given rectally, for treatment of postpartum haemorrhage, but this has not been evaluated in a placebo-controlled trial. Methods The study was conducted at East London Hospital Complex, Tembisa and Chris Hani Baragwanath Hospitals, South Africa. Routine active management of the third stage of labour was practised. Women with more than usual postpartum bleeding thought to be related to inadequate uterine contraction were invited to participate, and to sign informed consent. All routine treatment was given from a special 'Postpartum Haemorrhage Trolley'. In addition, participants who consented were enrolled by drawing the next in a series of randomised treatment packs containing either misoprostol 5 × 200 μg or similar placebo, which were given 1 orally, 2 sublingually and 2 rectally. Results With misoprostol there was a trend to reduced blood loss ≥500 ml in 1 hour after enrolment measured in a flat plastic 'fracture bedpan', the primary outcome (6/117 vs 11/120, relative risk 0.56; 95% confidence interval 0.21 to 1.46. There was no difference in mean blood loss or haemoglobin level on day 1 after birth 38.5°C (11/114 vs 2/118; 5.69, 1.29 to 25. In the misoprostol group 3 women underwent hysterectomy of whom 1 died, and there were 2 further maternal deaths. Conclusions Because of a lower than expected incidence of the primary outcome in the placebo group, the study was underpowered. We could not confirm the dramatic effect of misoprostol reported in several unblinded studies, but the results do not exclude a clinically important effect. Larger studies are needed to assess substantive outcomes and risks before misoprostol enters routine use.

    Full Text Available Antithrombotic drugs represent one of the leading pharmacological category used in clinical practice, especially in cardiovascular setting. Their demonstrated antithrombotic efficacy has been fundamental in the improvement of the management of many diseases related to athero-thrombotic or thromboembolic risk in prevention and treatment of cardiovascular events. Nonetheless, they are also associated with a not negligible haemorrhagic risk. Among these risks, intracranial bleeding represents the most feared, and should be kept in mind, prevented when possible and adequately managed when occurs. In this article the intracranial haemorrhagic risk associated to drugs vitamin K antagonists and new oral anticoagulants is reviewed.

    Directory of Open Access Journals (Sweden)

    Stelios eKokkoris

    2012-11-01

    Full Text Available Calcitonin gene-related peptide (CGRP is one of the most potent microvascular vasodilators identified to date. Vascular relaxation and vasodilation is mediated via activation of the CGRP receptor. This atypical receptor is made up of a G-protein-coupled receptor called calcitonin receptor-like receptor (CLR, a single transmembrane protein called receptor activity-modifying protein (RAMP, and an additional protein that is required for Gas coupling, known as receptor component protein (RCP. Several mechanisms involved in CGRP mediated relaxation have been identified. These include nitric oxide (NO-dependent endothelium-dependent mechanisms or cAMP-mediated endothelium-independent pathways; the latter being more common. Subarachnoid haemorrhage (SAH is associated with cerebral vasoconstriction that occurs several days after the haemorrhage and is often fatal. The vasospasm occurs in 30–40% of patients and is the major cause of death from this condition. The vasoconstriction is associated with a decrease in CGRP levels in nerves and an increase in CGRP levels in draining blood, suggesting that CGRP is released from nerves to oppose the vasoconstriction. This evidence has led to the concept that exogenous CGRP may be beneficial in a condition that has proven hard to treat. The present article reviews: a the pathophysiology of delayed ischaemic neurologic deficit after SAH b the basics of the CGRP receptor structure, signal transduction and vasodilatation mechanisms and c the studies that have been conducted so far using CGRP in both animals and humans with SAH.

    The aim of this critical review is to determine whether endovascular treatment (EVT) of a subarachnoid haemorrhage (SAH) has better patient outcomes than neurosurgical treatment (NST). A review of six cohort studies (listed in Table 1) was carried out and the main findings were summarised in the conclusion. In addition the list of author's recommendations is included at the end of the paper. Theatre practitioners involved in neurosurgery might find this review useful in enhancing their understanding of how SAH is currently treated. It could also bring some insights about the reasons why a particular modality of the treatment was chosen for their patient. PMID:26016283

  8. Cerebrospinal fluid from patients with subarachnoid haemorrhage and vasospasm enhances endothelin contraction in rat cerebral arteries.

    Directory of Open Access Journals (Sweden)

    Barbara Assenzio

    Full Text Available INTRODUCTION: Previous studies have suggested that cerebrospinal fluid from patients with subarachnoid hemorrhage (SAH leads to pronounced vasoconstriction in isolated arteries. We hypothesized that only cerebrospinal fluid from SAH patients with vasospasm would produce an enhanced contractile response to endothelin-1 in rat cerebral arteries, involving both endothelin ETA and ETB receptors. METHODS: Intact rat basilar arteries were incubated for 24 hours with cerebrospinal fluid from 1 SAH patients with vasospasm, 2 SAH patients without vasospasm, and 3 control patients. Arterial segments with and without endothelium were mounted in myographs and concentration-response curves for endothelin-1 were constructed in the absence and presence of selective and combined ETA and ETB receptor antagonists. Endothelin concentrations in culture medium and receptor expression were measured. RESULTS: Compared to the other groups, the following was observed in arteries exposed to cerebrospinal fluid from patients with vasospasm: 1 larger contractions at lower endothelin concentrations (p<0.05; 2 the increased endothelin contraction was absent in arteries without endothelium; 3 higher levels of endothelin secretion in the culture medium (p<0.05; 4 there was expression of ETA receptors and new expression of ETB receptors was apparent; 5 reduction in the enhanced response to endothelin after ETB blockade in the low range and after ETA blockade in the high range of endothelin concentrations; 6 after combined ETA and ETB blockade a complete inhibition of endothelin contraction was observed. CONCLUSIONS: Our experimental findings showed that in intact rat basilar arteries exposed to cerebrospinal fluid from patients with vasospasm endothelin contraction was enhanced in an endothelium-dependent manner and was blocked by combined ETA and ETB receptor antagonism. Therefore we suggest that combined blockade of both receptors may play a role in counteracting vasospasm in

    Objective To investigate the initial symptoms, onset time and predisposing factors of acute cerebral haemorrhage in order to more effectively prevent cerebral haemorrhage. Methods 728 cases with acute cerebral haemorrhage were collected in recent 8 years. The initial symptoms,onset time and predisposing factors of all the patients were investigated. Results Acute cerebral haemorrhage in 582 caces (79.9%) occurred at time between 6am and 18pm and 146 cases (20%) at night. The main predisposing causes of acute cerebral haemorrhage were the playing of chess, cards and mahjong (16.1%), quarrels (12.8%), overwork (11.7%), alcoholism (7.2%) and so on. The most common initial symptom was hemianesthesia, accounting for 16.2%, others were vertigo (13.0%), headache ( 11.4%), amaurosis fugax ( 9.3%), speech ambiguity ( 8.6%) and transitory visual disturbance (7.9%). Conclusions The preventive measures of cerebral haemorrhage should be focused on daytime, especially in the morning. Sixteen locations where the cerebral haemorrhage is prone to happen should be paid more attention to by the patients with hypertension and the medical staff. Thirteen symptoms,such as hemianesthesia and vertigo,are the aurae of cerebral haemorrhage.%目的 调查急性脑出血患者首发症状、发病时间和诱因,旨在更有效预防脑出血发病.方法 搜集调查近8年728例脑出血患者临床资料,分析其首发症状、发病时问和诱因. 结果 6:00~18:00发病582例占79.9%.18:00~6:00发病146例,占20.0%.脑出血发病第1位诱因是麻将棋牌,达117例,占16.1%,其次分别为争吵93例(12.8%),过劳85例(11.7%),酗酒53例(7.2%)等.首发症状最多见的足偏身麻木,118例,占16.2%;其次为突发眩晕,其他排列顺序依次为:头痛、一过性黑朦、言语含糊、短暂性视力障碍. 结论 脑出血发病预防重点应放在白天,尤其是上午;16种脑出血好发诱因应引起高血压患者和医务人员的重视,偏身麻木、眩晕等13

    Intrathecal baclofen infusion has demonstrated effectiveness in decreasing spasticity of spinal origin. Oral antispasticity medication is minimally effective or not well tolerated in cerebral palsy. This study assessed the effectiveness of intrathecal baclofen in reducing spasticity in cerebral palsy. Candidates were screened by randomized, double-blind, intrathecal injections of baclofen and placebo. Responders were defined as those who experienced an average reduction of 1.0 in the lower extremities on the Ashworth Scale for spasticity. Responders received intrathecal baclofen via the SynchroMed System and were followed for up to 43 months. Fifty-one patients completed screening and 44 entered open-label trials. Lower-extremity spasticity decreased from an average baseline score of 3.64 to 1.90 at 39 months. A decrease in upper extremity spasticity was evidenced over the same study period. Forty-two patients reported adverse events. Most common reports were hypotonia, seizures (no new onset), somnolence, and nausea or vomiting. Fifty-nine percent of the patients experienced procedural or system-related events. Spasticity in patients with cerebral palsy can be treated effectively by continuous intrathecal baclofen. Adverse events, although common, were manageable. PMID:10695888

    Thrombolysis is proposed for the acute treatment of cerebral infarction as it is able to recanalize occluded arteries and thus potentially restore normal perfusion of the cerebral parenchyma, but the results concerning the efficacy of this treatment are still inconclusive. However, it has been fully demonstrated that thrombolytic treatment, leads to a significant reduction in mortality, in patients with acute myocardial infarction. Data from all of the pilot studies using SK or tPA treatment in acute stroke are described in this review, which underlines the incidence of hemorrhagic transformation (hemorrhagic infart and parenchymal hematoma) and its possible correlation to clinical worsening. Pharmacological, experimental and clinical studies encourage the carrying out of large-scale clinical trials using thrombolytics in patients with acute cerebral infarction. Significant data relating to ongoing controlled clinical trials will be available in the near future; only after the analysis of these results will it be possible to confirm the efficacy of thrombolytics in acute stroke.

    1984-07-01

    The diagnostic accuracy of cerebral ultrasound for periventricular haemorrhage was determined by comparing this with necropsy findings in 30 preterm neonates of 30 weeks' gestation or less and birthweight under 1500 g. Ultrasound gave an accurate diagnosis of 85% in infants with germinal layer haemorrhage, 92% in intraventricular haemorrhage, and 97% in intracerebral haemorrhage. False positive errors were caused by vascular congestion; false negative errors occurred when the maximum dimension of haemorrhage was less than 3 mm. Cerebral ultrasound gave a diagnostic accuracy of 63% for periventricular leucomalacia. False negative errors occurred when periventricular leucomalacia was microscopic or when it was out of range of the scanner. The maximum width of the germinal layer was measured in 77 neonates of gestational age 23 to 36 weeks who died and had no periventricular haemorrhage at necropsy. The progressive involution of the germinal layer with increasing gestational age paralleled the steady decrease in incidence of periventricular haemorrhage diagnosed over the same gestational age range. Neonates of the youngest gestational age who had the most extensive germinal layers also had the highest risk for periventricular haemorrhage. PMID:6465933

    Full Text Available La cocaína es la segunda droga de comercio ilegal más consumida en España después del cannabis. El número de pacientes atendidos en los servicios de urgencias tras consumir cocaína y los casos de muerte secundarios al consumo de la misma han ido aumentando hasta multiplicarse por seis en los últimos años. El consumo de este alcaloide ocasiona efectos nocivos, constatados sobre diferentes órganos y sistemas corporales, e incluso la muerte. A nivel del SNC destaca, por su gravedad e incidencia, la patología cerebro-vascular hemorrágica (PCVH. Este tipo de cuadro se halla asociado al consumo de drogas ilícitas entre el 9,5% y el 34% de los accidentes vasculares en menores de 45 años, siendo la cocaína la más frecuentemente implicada en su presentación. Por otro lado, la rotura de un aneurisma o malformación arteriovenosa se ha detectado hasta en el 50% de los pacientes con PCVH secundarios al consumo de cocaína. Presentamos tres casos de muerte súbita en adultos por patología cerebro-vascular hemorrágica asociada al consumo de cocaína.Cocaine is the second most frequent illegal drug consumed in Spain after cannabis. A significant increase has occurred in the number of individuals treated in emergency departments after cocaine use just as in the number of cocaine-related deaths. These rates have been actually multiplied by six in the latest years. Cocaine causes injury in different organ systems, even death. In the CNS the use of cocaine is frequently associated with cerebral haemorrhage. Stroke in young adults below 45 years is usually related to drug use between 9,5% and 34% of cases, and cocaine is the most frequently mentioned drug. Otherwise, even 50% of cocaine-related stroke is the result of rupture of saccular aneurysms involving the arteries at the base of the brain and vascular malformation. In this paper, we present three cases of sudden death in adults due to cerebral haemorrhage associated with cocaine use.

    This study investigated performance and physiology to understand pacing strategies in elite Paralympic athletes with cerebral palsy (CP). Six Paralympic athletes with CP and 13 able-bodied (AB) athletes performed two trials of eight sets of 10 shuttles (total 1600m). One trial was distance-deceived (DEC, 1000 m + 600 m) one trial was nondeceived (N-DEC, 1600 m). Time (s), heart rate (HR, bpm), ratings of perceived exertion (RPE, units), and electromyography of five bilateral muscles (EMG) were recorded for each set of both trials. The CP group ran slower than the AB group, and pacing differences were seen in the CP DEC trial, presenting as a flat pacing profile over the trial (P < 0.05). HR was higher and RPE was lower in the CP group in both trials (P < 0.05). EMG showed small differences between groups, sides, and trials. The present study provides evidence for a possible pacing strategy underlying exercise performance and fatigue in CP. The results of this study show (1) underperformance of the CP group, and (2) altered pacing strategy utilization in the CP group. We proposed that even at high levels of performance, the residual effects of CP may negatively affect performance through selection of conservative pacing strategies during exercise.

  5. Cerebral angiography in the rat with mammographic equipment: a simple, cost-effective method for assessing vasospasm in experimental subarachnoid haemorrhage

    International Nuclear Information System (INIS)

    We report quantification of vasospasm following subarachnoid haemorrhage (SAH) and the effect of a new antivasospastic free radical scavenger (AVS) in rats, using an angiographic technique developed in our laboratory. We acquired single-exposure angiograms with mammographic equipment, using a 0.1 mm diameter focal spot and single-emulsion mammographic films. Contrast medium was injected through a PE50 catheter in the common carotid artery, after the external carotid artery had been ligated to divert flow towards the internal carotid artery territory. Measurements of the M1 and A1 segments and of the middle third of the basilar artery were made by projecting the angiograms directly as slides and using the endovascular catheter as an internal reference. We tested the technique on 40 male albino Sprague-Dawley rats divided into four groups: sham-operated+saline, SAH+saline, sham-operated+AVS and SAH+AVS. We were able to measure the diameter of the principal intracranial arteries in all the animals. With our technique, which is cost-effective when compared to many of those reported recently, we could detect intracranial vasospasm in all untreated rats with SAH, and confirm antivasospastic effects of AVS.

    Cerebral atrophy is a compound measure of the neurodegenerative component of multiple sclerosis (MS) and a conceivable outcome measure for clinical trials monitoring the effect of neuroprotective agents. In this study, we evaluate the rate of cerebral atrophy in a 6-month period, investigate the predictive and explanatory value of other magnetic resonance imaging (MRI) measures in relation to cerebral atrophy, and determine sample sizes for future short-term clinical trials using cerebral atrophy as primary outcome measure. One hundred thirty-five relapsing-remitting multiple sclerosis patients underwent six monthly MRI scans from which the percentage brain volume change (PBVC) and the number and volume of gadolinium (Gd)-enhancing lesions, T2 lesions, and persistent black holes (PBH) were determined. By means of multiple linear regression analysis, the relationship between focal MRI variables and PBVC was assessed. Sample size calculations were performed for all patients and subgroups selected for enhancement or a high T2 lesion load at baseline. A significant atrophy occurred over 6 months (PBVC = -0.33%, SE = 0.061, p < 0.0001). The number of baseline T2 lesions (p = 0.024), the on-study Gd-enhancing lesion volume (p = 0.044), and the number of on-study PBHs (p = 0.003) were associated with an increased rate of atrophy. For a 50% decrease in rate of atrophy, the sample size calculations showed that approximately 283 patients per arm are required in an unselected sampled population and 185 patients per arm are required in a selected population. Within a 6-month period, significant atrophy can be detected and on-study associations of PBVC and PBHs emphasizes axonal loss to be a driving mechanism. Application as primary outcome measure in short-term clinical trials with feasible sample size requires a potent drug to obtain sufficient power. (orig.)

    Treatment protocols for pediatric diabetic ketoacidosis (DKA) vary considerably among centers in the USA and worldwide. The optimal protocol for intravenous (IV) fluid administration is an area of particular controversy, mainly in regard to possible associations between rates of IV fluid infusion and the development of cerebral edema (CE), the most common and the most feared complication of DKA in children. Theoretical concerns about associations between osmotic fluid shifts and CE have prompted recommendations for conservative fluid infusion during DKA. However, recent data suggest that cerebral hypoperfusion may play a role in cerebral injury associated with DKA. Currently, there are no existing data from prospective clinical trials to determine the optimal fluid treatment protocol for pediatric DKA. The Pediatric Emergency Care Applied Research Network FLUID (FLuid therapies Under Investigation in DKA) study is the first prospective randomized trial to evaluate fluid regimens for pediatric DKA. This 13-center nationwide factorial design study will evaluate the effects of rehydration rate and fluid sodium content on neurological status during DKA treatment, the frequency of clinically overt CE and long-term neurocognitive outcomes following DKA.

    Cerebral vasospasm is a recognised but poorly understood complication for many patients who have aneurysmal subarachnoid haemorrhage and can lead to delayed ischaemic neurological deficit (stroke). Morbidity and mortality rates for vasospasm are high despite improvements in management. Since the middle of the 1970s, much has been written about the treatment of cerebral vasospasm. Hypervolaemia, hypertension, and haemodilution (triple-H) therapy in an intensive-care setting has been shown in some studies to improve outcome and is an accepted means of treatment, although a randomised controlled trial has never been undertaken. In this review, the rationale for this approach will be discussed, alongside new thoughts and future prospects for the management of this complex disorder.

    The authors describe a case of L-asparaginase induced intracranial thrombosis and subsequent haemorrhage in a newly diagnosed 30-year-old man with acute lymphoblastic leukaemia who was successfully managed by surgical intervention. At presentation, he had a Glasgow Coma Score of 7\\/15, was aphasic and had dense right hemiplegia. Neuroimaging revealed an acute anterior left middle cerebral artery infarct with parenchymal haemorrhagic conversion, mass effect and subfalcine herniation. He subsequently underwent left frontal craniotomy and evacuation of large frontal haematoma and decompressive craniectomy for cerebral oedema. Six months postoperatively he underwent titanium cranioplasty. He had made good clinical recovery and is currently mobilising independently with mild occasional episodes of expressive dysphasia, difficulty with fine motor movement on the right side, and has remained seizure free. This is the first documented case of L-asparaginase induced haemorrhagic stroke managed by neurosurgical intervention. The authors emphasise the possible role of surgery in managing chemotherapy induced intracranial complications.

METHODS 329 patients with TIA or mild ischemic cevebral stroke wasrandonmly assigned to ticlopidine group(165 case) or aspirin group (164 case) in this study.These patrents were randomly allocated to receive either 250mg trclopidine or 50mg aspirin daily and didnd take any other platelet antiaggregating drugs. Time of eacn follow up visit was one to two months. Follow up lasted for 6 to 18 months. RESULTS The event rate for stroke or death from any cause was 8.3% in ticlopidine group arid 14.9% in aspirin group. This repesented a risk reduction of 44.3%(95% cofidence interval, 0.29-0.94) for ticiopidine group as compared with aspirin group. The event raite for ischemic cerebral stroke or myocarction of ticlopidine group(7.0%)was lower than that cf aspirin group(14.8%)(P<0.05).A riskreduction of 52.7%(95% confidence interval,0.24-0.92) for ticlopidine group compared with aspirin group. The rate of adverse effects of ticlopidine group and aspirin group were 6.9% and 11.0% during the trial ,but this was not statistically significant(P<0.05).DISCUSSION and CONCLUSION Therapeutic efficacy for the prevention oi ischemic stroke of ticlopidine was better than that of aspirin, the rate of side effects in ticlopidine group and aspirin group are not statistically significant. So ticiopidine could serve as a first-line drug for the prevention of ischemic stroke.

    INTRODUCTION: We report the case of a 53-year-old farmer with a 5-day history of severe headache, photophobia and neck stiffness. Full blood count (platelets 173), coagulation screen were normal throughout. Liver function tests remained normal apart from an elevated gamma-GT (156). CT Brain was normal. CSF analysis showed a WCC of 454\\/mm(3) (60% lymphocytes), elevated CSF protein (1.42 g\\/l) and a normal CSF glucose. He was commenced on IV antibiotics and IV acyclivor and improved. On day 3 of admission, he complained of a sudden severe headache, became unresponsive (GCS 3\\/15). INVESTIGATIONS: CT Brain showed a massive left intraventricular haemorrhage. He died 4 days later. Subsequent serum serology for leptospirosis was positive. A repeat sample taken 4 days post-admission, showed a rising IgM indicating active leptospirosis. Detailed pathological examination confirmed intracerebral haemorrhage with normal cerebral vasculature. CONCLUSION: Leptospirosis is a rare cause of intracerebral haemorrhage even in the absence of coagulopathy.

    Full Text Available Expulsive choroidal haemorrhage is a dramatic and serious complication of cataract surgery that occurred in five patients out of ten thousand consecutive cataract surgeries performed by the author during the year 1989 and 1990. Report about this dreaded complication after cataract surgery are scanty and as far as I can remember I have not seen any report in Indian ophthalmic literature recently. Since cataract surgery forms the major part of intra ocular surgeries performed in our country, I thought it would be appropriate to report about this rare complication which may occur to all of us. Out of five cases 3 were males and 2 were females in the age group ranging between 45-72 years. Two eyes regained vision up to 6/12 after intra operative expulsive haemorrhage. All the eyes were salvaged by doing anterior sclerotomy. Diabetes, hypertension, glaucoma and myopia are the commonest predisposing factors.

    After aneurysmal subarachnoid haemorrhage (SAH), the clinical outcome depends upon the primary haemorrhage and a number of secondary insults in the acute post-haemorrhagic period. Some secondary insults are potentially preventable but prevention requires prompt recognition of cerebral or systemic....... Furthermore, the use of multi-modality monitoring is hampered by a lack of clinical studies that identify combinations of specific techniques in terms of clinical information and reliability. However, ischaemia at the tissue level can be detected by intracerebral microdialysis technique. Used together...... with the conventional monitoring systems, for example intracranial pressure measurements, transcranial Doppler ultrasound and modern neuro-imaging, direct assessment of biochemical markers by intracerebral microdialysis is promising in the advancement of neurointensive care of patients with SAH.

    Full Text Available Abstract Background Children with cerebral palsy receive a variety of long-term physical and occupational therapy interventions to facilitate development and to enhance functional independence in movement, self-care, play, school activities and leisure. Considerable human and financial resources are directed at the "intervention" of the problems of cerebral palsy, although the available evidence supporting current interventions is inconclusive. A considerable degree of uncertainty remains about the appropriate therapeutic approaches to manage the habilitation of children with cerebral palsy. The primary objective of this project is to conduct a multi-site randomized clinical trial to evaluate the efficacy of a task/context-focused approach compared to a child-focused remediation approach in improving performance of functional tasks and mobility, increasing participation in everyday activities, and improving quality of life in children 12 months to 5 years of age who have cerebral palsy. Method/Design A multi-centred randomized controlled trial research design will be used. Children will be recruited from a representative sample of children attending publicly-funded regional children's rehabilitation centers serving children with disabilities in Ontario and Alberta in Canada. Target sample size is 220 children with cerebral palsy aged 12 months to 5 years at recruitment date. Therapists are randomly assigned to deliver either a context-focused approach or a child-focused approach. Children follow their therapist into their treatment arm. Outcomes will be evaluated at baseline, after 6 months of treatment and at a 3-month follow-up period. Outcomes represent the components of the International Classification of Functioning, Disability and Health, including body function and structure (range of motion, activities (performance of functional tasks, motor function, participation (involvement in formal and informal activities, and environment (parent

    Subclinical acute ischaemic lesions on brain magnetic resonance imaging have recently been described in spontaneous intracerebral haemorrhage, and may be important to understand pathophysiology and guide treatment. The underlying mechanisms are uncertain. We tested the hypothesis that ischaemic lesions are related to magnetic resonance imaging markers of the severity and type of small-vessel disease (hypertensive arteriopathy or cerebral amyloid angiopathy) in a multicentre, cross-sectional study. We studied consecutive patients with intracerebral haemorrhage from four specialist stroke centres, and age-matched stroke service referrals without intracerebral haemorrhage. Acute ischaemic lesions were assessed on magnetic resonance imaging (imaging. White matter changes and cerebral microbleeds were rated with validated scales. We investigated associations between diffusion-weighted imaging lesions, clinical and radiological characteristics. We included 114 patients with intracerebral haemorrhage (39 with clinically probable cerebral amyloid angiopathy) and 47 age-matched controls. The prevalence of diffusion-weighted imaging lesions was 9/39 (23%) in probable cerebral amyloid angiopathy-related intracerebral haemorrhage versus 6/75 (8%) in the remaining patients with intracerebral haemorrhage (P = 0.024); no diffusion-weighted imaging lesions were found in controls. Diffusion-weighted imaging lesions were mainly cortical and were associated with mean white matter change score (odds ratio 1.14 per unit increase, 95% confidence interval 1.02-1.28, P = 0.024) and the presence of strictly lobar cerebral microbleeds (odds ratio 3.85, 95% confidence interval 1.15-12.93, P = 0.029). Acute, subclinical ischaemic brain lesions are frequent but previously underestimated after intracerebral haemorrhage, and are three times more common in cerebral amyloid angiopathy-related intracerebral haemorrhage than in other intracerebral haemorrhage types. Ischaemic brain lesions are

    Full Text Available Abstract Background Although hippotherapy treatment has been demonstrated to have therapeutic effects on children with cerebral palsy, the samples used in research studies have been very small. In the case of hippotherapy simulators, there are no studies that either recommend or advise against their use in the treatment of children with cerebral palsy. The aim of this randomised clinical study is to analyse the therapeutic effects or the contraindications of the use of a commercial hippotherapy simulator on several important factors relating to children with cerebral palsy such as their motor development, balance control in the sitting posture, hip abduction range of motion and electromyographic activity of adductor musculature. Methods/Design The study is a randomised controlled trial. It will be carried out with a sample of 37 children with cerebral palsy divided into two treatment groups. Eligible participants will be randomly allocated to receive either (a Treatment Group with hippotherapy simulator, maintaining sitting posture, with legs in abduction and rhythmic movement of the simulator or (b Treatment Group maintaining sitting posture, with legs in abduction and without rhythmic movement of the simulator. Data collection and analysis: all measurements will be carried out by a specially trained blind assessor. To ensure standardization quality of the assessors, an inter-examiner agreement will be worked out at the start of the study. The trial is funded by the Department of Research, Innovation and Development of the Regional Government of Aragon (Official Bulletin of Aragon 23 July 2007, project number PM059/2007. Discussion Interest in this project is due to the following factors: Clinical originality (there are no previous studies analysing the effect of simulators on the population group of children with CP, nor any studies using as many variables as this project; Clinical impact (infantile cerebral palsy is a chronic multisystemic

    Full Text Available La hemorragia postparto es una de las complicaciones obstétricas más temidas y es una de las tres primeras causas de mortalidad materna en el mundo. Universalmente se define como la pérdida hemática superior a 500 ml tras un parto vaginal o a 1.000 ml tras una cesárea. La hemorragia postparto precoz (HPP es aquella que ocurre durante las primeras 24 horas tras el parto y es generalmente la más grave. Las causas de HPP incluyen atonía uterina, traumas/laceraciones, retención de productos de la concepción y alteraciones de la coagulación, siendo la más frecuente la atonía. El diagnóstico es clínico y el tratamiento ha de abarcar unas medidas generales de soporte vital y otras más específicas de carácter etiológico. Afortunadamente, es potencialmente evitable en la mayoría de los casos si se sigue una adecuada estrategia de prevención activa y sistemática en la fase de alumbramiento de todos los partos.Postpartum haemorrhage is one of the most dreaded obstetric complications and one of the three main causes of maternal mortality in the world. It is universally defined as haematic loss above 500 ml following a vaginal delivery or above 1,000 ml following a caesarean. An early postpartum haemorrhage (EPH is one that occurs during the first 24 hours following delivery and is generally the most serious. The causes of EPH include uterine atony, trauma/lacerations, retention of products of conception and alterations of coagulation, with atony being the most frequent. Diagnose is clinical and treatment must include general life support measures and other more specific measures of an etiological character. Fortunately, in the majority of cases it is potentially avoidable if an adequate strategy of active and systematic prevention is followed in the delivery phase of all labors.

    Full Text Available The Ebola virus is a highly virulent, single-stranded ribonucleic acid virus which affects both humans and apes and has fast become one of the world’s most feared pathogens. The virus induces acute fever and death, with haemorrhagic syndrome occurring in up to 90% of patients. The known species within the genus Ebolavirus are Bundibugyo, Sudan, Zaïre, Reston and Taï Forest. Although endemic in Africa, Ebola has caused worldwide anxiety due to media hype and concerns about its international spread, including through bioterrorism. The high fatality rate is attributed to unavailability of a standard treatment regimen or vaccine. The disease is frightening since it is characterised by rapid immune suppression and systemic inflammatory response, causing multi-organ and system failure, shock and often death. Currently, disease management is largely supportive, with containment efforts geared towards mitigating the spread of the virus. This review describes the classification, morphology, infective process, natural ecology, transmission, epidemic patterns, diagnosis, clinical features and immunology of Ebola, including management and epidemic containment strategies.

    Full Text Available Question: In children with cerebral palsy, does a 6-month physical activity stimulation program improve physical activity, mobility capacity, fitness, fatigue and attitude towards sports more than usual paediatric physiotherapy? Design: Multicentre randomised controlled trial with concealed allocation, blinded assessments and intention-to-treat analysis. Participants: Forty-nine walking children (28 males aged 7–13 years with spastic cerebral palsy and severity of the disability classified as Gross Motor Function Classification System level I–III. Intervention: The intervention group followed a 6-month physical activity stimulation program involving counselling through motivational interviewing, home-based physiotherapy, and 4 months of fitness training. The control group continued their usual paediatric physiotherapy. Outcome measures: Primary outcomes were walking activity (assessed objectively with an activity monitor and parent-reported physical activity (Activity Questionnaire for Adults and Adolescents. Secondary outcomes were: mobility capacity, consisting of Gross Motor Function Measure-66 (GMFM-66, walking capacity and functional strength, fitness (aerobic and anaerobic capacity, muscle strength, self-reported fatigue, and attitude towards sport (child and parent. Assessments were performed at baseline, 4 months, 6 months and 12 months. Results: There were no significant intervention effects for physical activity or secondary outcomes at any assessment time. Positive trends were found for parent-reported time at moderate-to-vigorous intensity (between-group change ratio = 2.2, 95% CI 1.1 to 4.4 and GMFM-66 (mean between-group difference = 2.8 points, 95% CI 0.2 to 5.4 at 6 months, but not at 12 months.

    In 1985, the EORTC Radiotherapy Co-operative Group launched a randomised phase III study comparing high-dose (59.4 Gy in 6.5 weeks) versus low-dose (45 Gy in 5 weeks) radiotherapy with conventional techniques in patients diagnosed with low-grade cerebral glioma. The primary endpoint of the study was survival. No difference in survival was observed between the two treatment strategies. A quality of life (QoL) questionnaire consisting of 47 items assessing a range of physical, psychological, social, and symptom domains was included in the trial to measure the impact of treatment over time. Patients who received high-dose radiotherapy tended to report lower levels of functioning and more symptom burden following completion of radiotherapy. These group differences were statistically significant for fatigue/malaise and insomnia immediately after radiotherapy and in leisure time and emotional functioning at 7-15 months after randomisation. These findings suggest that for conventional radiotherapy for low-grade cerebral glioma, a schedule of 45 Gy in 5 weeks not only saves valuable resources, but also spares patients a prolonged treatment at no loss of clinical efficacy.

    Full Text Available The objective of this study was to examine the effects of estrogen-based hormone therapy (HT on regional cerebral metabolism in postmenopausal women (mean age = 58, SD = 5 at risk for development of dementia. The prospective clinical trial design included pre- and post-intervention neuroimaging of women randomized to continue (HT+ or discontinue (HT- therapy following an average of 10 years of use. The primary outcome measure was change in brain metabolism during the subsequent two years, as assessed with fluorodeoxyglucose-18 positron emission tomography (FDG-PET. Longitudinal FDG-PET data were available for 45 study completers. Results showed that women randomized to continue HT experienced relative preservation of frontal and parietal cortical metabolism, compared with women randomized to discontinue HT. Women who discontinued 17-β estradiol (17βE-based HT, as well as women who continued conjugated equine estrogen (CEE-based HT, exhibited significant decline in metabolism of the precuneus/posterior cingulate cortical (PCC area. Significant decline in PCC metabolism was additionally seen in women taking concurrent progestins (with either 17βE or CEE. Together, these findings suggest that among postmenopausal subjects at risk for developing dementia, regional cerebral cortical metabolism is relatively preserved for at least two years in women randomized to continue HT, compared with women randomized to discontinue HT. In addition, continuing unopposed 17βE therapy is associated specifically with preservation of metabolism in PCC, known to undergo the most significant decline in the earliest stages of Alzheimer's disease.ClinicalTrials.gov NCT00097058.

    2012-03-01

    Full Text Available Abstract Background Range of motion deficits of the lower extremity occur in about the half of the children with spastic cerebral palsy (CP. Over time, these impairments can cause joint deformities and deviations in the children's gait pattern, leading to limitations in moblity. Preventing a loss of range of motion is important in order to reduce secondary activity limitations and joint deformities. Sustained muscle stretch, imposed by orthotic management in rest, might be an effective method of preventing a decrease in range of motion. However, no controlled study has been performed. Methods A single blind randomised controlled trial will be performed in 66 children with spastic CP, divided over three groups with each 22 participants. Two groups will be treated for 1 year with orthoses to prevent a decrease in range of motion in the ankle (either with static or dynamic knee-ankle-foot-orthoses and a third group will be included as a control group and will receive usual care (physical therapy, manual stretching. Measurements will be performed at baseline and at 3, 6, 9 and 12 months after treatment allocation. The primary outcome measure will be ankle dorsiflexion at full knee extension, measured with a custom designed hand held dynamometer. Secondary outcome measures will be i ankle and knee flexion during gait and ii gross motor function. Furthermore, to gain more insight in the working mechanism of the orthotic management in rest, morphological parameters like achilles tendon length, muscle belly length, muscle fascicle length, muscle physiological cross sectional area length and fascicle pennation angle will be measured in a subgroup of 18 participants using a 3D imaging technique. Discussion This randomised controlled trial will provide more insight into the efficacy of orthotic management in rest and the working mechanisms behind this treatment. The results of this study could lead to improved treatments. Trial Registration Number

    International Nuclear Information System (INIS)

    The aim of this study was to prospectively evaluate a clinical protocol including transcranial doppler (TCD), xenon-CT (Xe-CT) and angiography, for the detection of vasospasm leading to critical reduction of regional cerebral blood flow (rCBF) in both ventilated and sedated SAH patients, i.e. patients in whom clinical evaluation was not possible. Seventy-six patients were prospectively included in a surveillance protocol for daily TCD vasospasm monitoring. When TCD showed a Vmean above 120 cm/sec in the middle cerebral artery (MCA), patients underwent Xe-CT study. If rCBF in the MCA was reduced to below 20 ml /100 g / min or if there was a reduction in the rCBF with significant asymmetry between the two AMCAs, angiography was performed. Conversely, further Xe-CT and angiography were not obtained unless the TCD Vmean values reached values above 160 cm/sec. In 35 patients. Vmean attained values above 120 cm/sec, but only in five of them, rCBF was suggestive of vasospasm, and angiography confirmed the diagnosis in four. The protocol suggests that in sedated and ventilated patients, detection of a critical rCBF reduction due to vasospasm is possible to allow for more specific treatment and to reduce undue medical complications.

    Full Text Available Abstract Background Rehabilitation for children with hemiplegic cerebral palsy (HCP aimed to improve function of the impaired upper limb (UL uses a wide range of intervention programs. A new rehabilitative approach, called Action-Observation Therapy, based on the recent discovery of mirror neurons, has been used in adult stroke but not in children. The purpose of the present study is to design a randomised controlled trial (RCT for evaluating the efficacy of Action-Observation Therapy in improving UL activity in children with HCP. Methods/Design The trial is designed according to CONSORT Statement. It is a randomised, evaluator-blinded, match-pair group trial. Children with HCP will be randomised within pairs to either experimental or control group. The experimental group will perform an Action-Observation Therapy, called UP-CAT (Upper Limb-Children Action-Observation Training in which they will watch video sequences showing goal-directed actions, chosen according to children UL functional level, combined with motor training with their hemiplegic UL. The control group will perform the same tailored actions after watching computer games. A careful revision of psychometric properties of UL outcome measures for children with hemiplegia was performed. Assisting Hand Assessment was chosen as primary measure and, based on its calculation power, a sample size of 12 matched pairs was established. Moreover, Melbourne and ABILHAND-Kids were included as secondary measures. The time line of assessments will be T0 (in the week preceding the onset of the treatment, T1 and T2 (in the week after the end of the treatment and 8 weeks later, respectively. A further assessment will be performed at T3 (24 weeks after T1, to evaluate the retention of effects. In a subgroup of children enrolled in both groups functional Magnetic Resonance Imaging, exploring the mirror system and sensory-motor function, will be performed at T0, T1 and T2.

    Objective To evaluate the efficacy and safety of defibrase in patients with acute cerebral infarction by a large sample,multicenter, randomized, double-blind, placebo-controlled clinical trial.Methods Patients with acute cerebral infarction within 12 hours of stroke onset were randomly assigned to receive either an initial intravenous infusion of defibrase 15 U plus normal saline 250 Ml or 250 Ml of normal saline only.Subsequent infusions of defibrase 15 U or placebo (normal saline) were given on the 3rd, 5th, 7th, and 9th day, respectively.Both groups received standard care of acute cerebral infarction. The primary efficacy outcome was functional status(Barthel Index) at 3 months after treatment. Safety outcome were bleeding events and mortality rate. Secondary outcome included Chinese Stroke Scale (CSS) score at 14 days and recurrence rate of stroke at 1 year. Results A total of 1053 patients were enrolled at 46 centers from September 2001 to July 2003, and 527 patients were randomly assigned to receive defibrase and 526 to receive placebo. A similar proportion of patients in both groups completed a full course of treatment. There was a significantly greater proportion of favorable functional status (Barthel Index ≥95) in defibrase group than in placebo group at 3 months (52.2% vs. 42.8%, P < 0.01), and the proportion of dependent functional status (Barthel Index ≤60) was a little lower in defibrase group compared with placebo group(27.7%vs. 32.4%). These differences were more obvious among patients who were treated within 6 hours of stroke onset.Patients in defibrase group had better improvement with respect to CSS score than those in placebo group at 14 days (P <0.05). Recurrence rate of stroke at 1 year was lower in the defibrase group compared with placebo group (6.2% vs. 10.1%,P = 0.053). Patients in defibrase group had higher risk of extracranial bleeding events (4.7%vs. 1.5%, P< 0.01) and a tendency of higher risk of symptomatic intracranial hemorrhage

    Background Indices of global tissue oxygen delivery and utilization such as mixed venous oxygen saturation, serum lactate concentration, and arterial hematocrit are commonly used to determine the adequacy of tissue oxygenation during cardiopulmonary bypass (CPB). However, these global measures may not accurately reflect regional tissue oxygenation and ischemic organ injury remains a common and serious complication of CPB. Near-infrared spectroscopy (NIRS) is a noninvasive technology that measures regional tissue oxygenation. NIRS may be used alongside global measures to optimize regional perfusion and reduce organ injury. It may also be used as an indicator of the need for red blood cell transfusion in the presence of anemia and tissue hypoxia. However, the clinical benefits of using NIRS remain unclear and there is a lack of high-quality evidence demonstrating its efficacy and cost effectiveness. Objective The aim of the patient-specific cerebral oxygenation monitoring as part of an algorithm to reduce transfusion during heart valve surgery (PASPORT) trial is to determine whether the addition of NIRS to CPB management algorithms can prevent cognitive decline, postoperative organ injury, unnecessary transfusion, and reduce health care costs. Methods Adults aged 16 years or older undergoing valve or combined coronary artery bypass graft and valve surgery at one of three UK cardiac centers (Bristol, Hull, or Leicester) are randomly allocated in a 1:1 ratio to either a standard algorithm for optimizing tissue oxygenation during CPB that includes a fixed transfusion threshold, or a patient-specific algorithm that incorporates cerebral NIRS monitoring and a restrictive red blood cell transfusion threshold. Allocation concealment, Internet-based randomization stratified by operation type and recruiting center, and blinding of patients, ICU and ward care staff, and outcome assessors reduce the risk of bias. The primary outcomes are cognitive function 3 months after

    The most important cerebrovascular injuries in newborn infants, particularly in preterm infants, are cerebral haemorrhage and ischemic injury. The typical cerebral vascular anatomy and the disturbance of cerebral haemodynamics play important roles in the pathophysiology. The term 'cerebral...... haemodynamics' includes cerebral blood flow (CBF), cerebral blood flow velocity, and cerebral blood volume (CBV). Therapy aimed at changing vascular anatomy is not available. Therefore, prevention of disturbances in CBF and CBV is pivotal. However, continuous monitoring of CBF and CBV is still unavailable for....... Using it even without knowing the exact level of CBF and CBV, it is possible to aim to keep CBF and CBV stable.

The aim of the proposed study is to determine the effect of the combination of posture-control insoles and ankle-foot orthoses (AFOs improving functional limitation in children with CP. Methods/Design The sample will be composed of 24 children with CP between four and 12 years of age. After the signing of the statement of informed consent, the children will be randomly allocated to two groups: a control group using AFOs alone and an experimental group using both posture-control insoles and AFOs. Evaluations will be performed on five occasions: without any accessory (insoles or AFOs, immediately after, one month after, six months after and one year after AFOs or insole and AFOs use. The evaluation will involve the analysis of gait, static and functional balance, mobility and hypertonia. The three-dimensional assessment of gait will involve the eight-camera SMART-D SMART-D 140® system (BTS Engineering, two Kistler force plates (model 9286BA and an eight-channel, wireless FREEEMG® electromyography (BTS Engineering. Static balance will be assessed using a Kistler force plate (model 9286BA. Clinical functional balance and mobility will be assessed using the Berg Balance Scale, Timed Up-and-Go Test and Six-Minute Walk Test. The posture-control insoles will be made of ethylene vinyl acetate, with thermal molding for fixation. The fixed orthoses will be made of polypropylene and attached to the ankle region (AFO.

    The present study aimed to investigate the behavior and neuronal morphological changes in the perihaemorrhagic tissue of the mouse intracerebellar haemorrhage experimental model. Adult male Swiss albino mice were stereotactically infused with collagenase type VII (0.4U/μl of saline) unilaterally in to the cerebellum, following anaesthesia. Motor deficits were assessed using open field and composite score for evaluating the mouse model of cerebellar ataxia at 1, 3, 7, 14 and 21 days after collagenase infusion. The animals were sacrificed at the same time interval for evaluation of perihaematomal neuronal degeneration using haematoxylin and eosin staining and Annexin V-FITC/Propidium iodide assay. At the end of the study, it was found that infusion of 0.4U collagenase produces significant locomotor and ataxic deficit in the mice especially within the first week post surgery, and that this gradually improved within three weeks. Neuronal degeneration evident by cytoplasmic shrinkage and nuclear pyknosis was observed at the perihaematomal area after one day; especially at 3 and 7 days post haemorrhage. By 21 days, both the haematoma and degenerating neurons in the perihaematomal area were phagocytosed and the remaining neuronal cells around the scar tissue appeared normal. Moreover, Annexin-V/propidium iodide-positive cells were observed at the perihaematomal area at 3 and 7 days implying that the neurons likely die via apoptosis. It was concluded that a population of potentially salvageable neurons exist in the perihaematomal area after cerebellar haemorrhage throughout a wide time window that could be amenable to treatment.

    The aim of this study is to investigate the effect of electro-acupuncture treatment in acute phase of cerebral infarction on the motor functions. In this randomly controlled trial, 86 patients were allocated to two groups, the experimental group given clinical and electro-acupuncture treatments for a period of 4 weeks, and the control group given clinical treatment plus active and/or passive functional exercise. The result showed that the level of impairment and disability in both groups were improvement according to the Chinese Stroke Scale, Brunnstrom-Fugl-Meyer score, and Barthel Index throughout the study and 3 months after. The motor functions and the activities of daily living (ADL) were improved significantly in the electro-acupuncture group as compared with the control group (P<0.05). Also, the results showed greater reduction of neurological deficit in the electro-acupuncture group than in the control group. Conclusion: Early acupuncture treatment for acute stroke patients may improve motor functions, and consequently the activities of daily living.

    Current management guidelines for CT scan-negative subarachnoid haemorrhage (SAH) patients recommend cerebral digital subtraction angiography (DSA). We aimed to investigate the utility of CT angiography (CTA) as a substitute for DSA in these patients. We included patients who presented with SAH confirmed by spectrophotometric xanthochromia analysis of cerebrospinal fluid (CSF) whereby the CT scan was negative. Electronic records were reviewed to collect data on non-contrast CT scan, CTA and DSA results. Patients without DSA or with other explanations for CSF xanthochromia were excluded. Sixty-three patients with CT scan-negative SAH were included. The diagnosis of SAH was confirmed by CSF analysis. All 63 patients underwent both DSA and CTA. Using DSA as the benchmark, CTA demonstrated a negative predictive value, positive predictive value, sensitivity and specificity of 98%, 82%, 90% and 96%, respectively, for the detection of intracranial aneurysms. CTA correctly identified patients in whom there were no underlying aneurysms responsible for SAH, with one patient with suspected dissection referred for further evaluation using MRI and DSA.

    2013-08-01

    During heavy exercise, hyperventilation-induced hypocapnia leads to cerebral vasoconstriction, resulting in a reduction in cerebral blood flow (CBF). A reduction in CBF would impair cerebral O2 delivery and potentially account for reduced exercise performance in hypoxia. We tested the hypothesis that end-tidal Pco2 (PETCO2) clamping in hypoxic exercise would prevent the hypocapnia-induced reduction in CBF during heavy exercise, thus improving exercise performance. We measured PETCO2, middle cerebral artery velocity (MCAv; index of CBF), prefrontal cerebral cortex oxygenation (cerebral O2Hb; index of cerebral oxygenation), cerebral O2 delivery (DO2), and leg muscle oxygenation (muscle O2Hb) in 10 healthy men (age 27 ± 7 years; VO2max 63.3 ± 6.6 mL/kg/min; mean ± SD) during simulated 15-km time trial cycling (TT) in normoxia and hypoxia (FIO2 = 0.10) with and without CO2 clamping. During exercise, hypoxia elevated MCAv and lowered cerebral O2Hb, cerebral DO2, and muscle O2Hb (P exercise in both normoxic and hypoxic conditions (P effect on either cerebral and muscle O2Hb (P = 0.118 and P = 0.124). Nevertheless, CO2 clamping elevated cerebral DO2 during TT in both normoxic and hypoxic conditions (P hypoxia and tended to have a greater effect on TT performance in hypoxia compared to normoxia (P = 0.097). However, post hoc analysis revealed no effect of CO2 clamping on TT performance either in normoxia (P = 0.588) or in hypoxia (P = 0.108). Our findings confirm that the hyperventilation-induced hypocapnia and the subsequent drop in cerebral oxygenation are unlikely to be the cause of the reduced endurance exercise performance in hypoxia.

  15. Hereditary haemorrhagic telangiectasia: a cause of preventable morbidity and mortality.

    LENUS (Irish Health Repository)

    Brady, A P

    2012-01-31

    Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant condition whose effects are mediated through deficient blood vessel formation and regeneration, with multisystem involvement. Patients are usually aware of resulting skin telangiectasia and epistaxis, but are also exposed to dangers posed by occult vascular malformations in other organs. About 15-35% of HHT patients have pulmonary AVMs (PAVMs), 10% have cerebral AVMs (CAVMs), 25-33% suffer significant GI blood loss from GI tract telangiectasia, and an unknown but high percentage have liver involvement. In total, 10% of affected individuals die prematurely or suffer major disability from HHT, largely because of bleeding from CAVMs and PAVMs, or paradoxical embolization through PAVMs. Screening for and early intervention to treat occult PAVMs and CAVMs can largely eliminate these risks, and should be undertaken in a specialist centre. The National HHT Center in The Mercy University Hospital in Cork is the referral centre for HHT screening in Ireland.

    This study was designed to assess the necessity for a second angiogram study in patients in whom initial angiography after primary subarachnoid haemorrhage (SAH) was negative. During a 12-year period, 122 of 694 patients (17.5 %) had negative initial angiograms. CT, available for 98 patients, showed a preponderance of subarachnoid blood in the perimesencephalic cisterns in 50 of 73 patients (68.5 %) in whom blood was visible on CT. Angiography, repeated in 67 patients, revealed an aneurysm in 4 (6 %): 2 had an aneurysm of the anterior communicating artery, 1 of the posterior inferior cerebellar artery, and 1 of the P2 segment of the posterior cerebral artery. CT showed subarachnoid blood in the interpeduncular and ambient cisterns in this last case, and a preponderance of subarachnoid blood outside the perimesencephalic cisterns in the remaining 3 patients.

    Full Text Available Background: Postpartum haemorrhage (PPH is the third-most common cause of maternal death in the United States and it is still the first prevalent cause of maternal death in developing countries. Active prevention of haemorrhage with an uterotonic or other new drugs leads to a decrease in postpartum vaginal haemorrhage. The aim of this study was to compare anti-haemorrhagic effect of Tranexamic acid (TXA and Misoprostol for PPH. Patients and Methods: In a double-blinded randomised control clinical trial, 200 women were included after Caesarean or natural vaginal delivery with abnormal PPH. They were divided into two equal intervention and control groups. Effect of intravenous TXA and Misoprostol for postpartum haemorrhage was examined. Results: The mean age of patients was 26.7 ± 6.5 years which ranged from 14 to 43 years. The sonographic gestational age in the group treated with TXA was 37.7 ± 3.4 weeks and it was 37.4 ± 3.3 weeks for the other group (P = 0.44. The haemorrhage in the TXA and Misoprostol groups was 1.2 ± 0.33 litres and 1.18 ± 0.47 litres, respectively (P = 0.79. The haemoglobin levels after 6-12 hours of labour, in TXA group was more than that of the Misoprostol group, but this difference was not statistically significant (P = 0.22 and P = 0.21, respectively. Conclusion: Regarding to the superior results in Misoprostol group in one hand and lack of significant differences between two groups in haemorrhage during labour, post-partum haemoglobin level and discharge haemoglobin level, we can state that Misoprostol has no specific preferences to TXA, but more studies with greater population are needed.

    Full Text Available INTRODUCTION: Cerebral palsy (CP is a group of permanent movement disorders that appear in early childhood. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often the problems occur during pregnancy; however, they may also occur during childbirth, or shortly after birth. Often the cause is unknown. AIM: To study the different antenatal maternal risk factors associated with cerebral palsy in the study group. MATERIA LS AND METHODS: Retrospective study was done to assess possible associated antenatal risk factors for cerebral palsy. Mothers of 100 cerebral palsy children were selected who are treated in Rani Chandramani Devi Hospital, a Government hospital in Visakhapa tn am, Andhra Pradesh State, India , from 2012 to 2014 and 100 controls, mothers of normal children were studied. Detailed antenatal history was obtained from the mothers of the children in both affected and control group. RESULTS: From the data, we conclude that the association of maternal anaemia with cerebral palsy is 7.3 times higher; association of maternal hypertension with cerebral palsy is 6.6 time higher, association with Pre - eclampsia is 6 times higher; association with Eclampsia is 8.6 times higher ; with antepartum haemorrhage, the association is 8.6 times higher and association of multiple pregnancy with cerebral palsy is 4.8 times higher than with controls. CONCLUSION: From this study of the role of antenatal risk factors, in the occurrence of cer ebral palsy in children it is concluded that the most common risk factor associated with cerebral palsy is the maternal anaemia and the other important risk factors associated being hypertension, pre eclampsia, eclampsia, antepartum haemorrhage and multipl e births.

    Full Text Available BACKGROUND: Cerebral palsy refers to permanent, mutable motor development disorders stemming from a primary brain lesion, causing secondary musculoskeletal problems and limitations in activities of daily living. The aim of the present study was to determine the effects of gait training combined with transcranial direct-current stimulation over the primary motor cortex on balance and functional performance in children with cerebral palsy. METHODS: A double-blind randomized controlled study was carried out with 24 children aged five to 12 years with cerebral palsy randomly allocated to two intervention groups (blocks of six and stratified based on GMFCS level (levels I-II or level III.The experimental group (12 children was submitted to treadmill training and anodal stimulation of the primary motor cortex. The control group (12 children was submitted to treadmill training and placebo transcranial direct-current stimulation. Training was performed in five weekly sessions for 2 weeks. Evaluations consisted of stabilometric analysis as well as the administration of the Pediatric Balance Scale and Pediatric Evaluation of Disability Inventory one week before the intervention, one week after the completion of the intervention and one month after the completion of the intervention. All patients and two examiners were blinded to the allocation of the children to the different groups. RESULTS: The experimental group exhibited better results in comparison to the control group with regard to anteroposterior sway (eyes open and closed; p<0.05, mediolateral sway (eyes closed; p<0.05 and the Pediatric Balance Scale both one week and one month after the completion of the protocol. CONCLUSION: Gait training on a treadmill combined with anodal stimulation of the primary motor cortex led to improvements in static balance and functional performance in children with cerebral palsy.

    Full Text Available BACKGROUND : It is estimated that every year , 15 million people suffer from stroke in the world out of which six million die and another five million are permanently disabled. There are limited studies on the infratentorial haemorrhage cases of stroke especially in India. In this context , this present study was conducted to find o ut management and prognosis assessment of infratentorial haemorrhage cases admitted in a tertiary care hospital in Chennai , India. METHODS : This is a prospective observational study conducted on the stroke cases admitted to the neurology department of Sri Ramachandra Medical College Hospital ( SRMC , Chennai during August 2010 to February 2013. The prognosis of the patients was assessed through National Institutions of Health Stroke scale and Modified Rankin Prognostic Score. RESULTS : A total of 1 , 809 cases of stroke were admitted during this period out of which 43 were i nfratentorial haemorrhage cases ( 2.4% . It was found that 88.3% undergone treatment for reduction of cerebral edema , 83.7% for prevention of seizures , 81.4% for reduction of systemic hyperte nsion , 79.0% were given antibiotic therapy while 39.5% required ventilatory support. Majority of the patients were in the first category of Modified Rankin Prognosis score ( 37.2% while as per National Institutions of Health Stroke Scale scoring , it was fo und that a majority of the patents were in moderate category of stroke ( 60.5% . The case fatality rate was found to be 25.6%. The case fatality rate was found to be insignificantly higher in cerebellar haemorrhage cases ( 23.8% compa red to pontine hemorrhage cases ( 19.1% . CONCLUSIONS : The proportion of infratentorial type of haemorrhage is comparatively less common type than supratentorial type and ischaemic type of cerebral stroke. The case fatality rate was found to be 25.6% which was similar to other studies. There is a need for further studies on infratentorial haemorrhage.

    Full Text Available Spontaneous splenic haemorrahge and rupture is a rare but life-threatening condition requiring urgent diagnosis and treatment. Splenic haemorrhage and rupture precipitated by thrombolytic or antiocoagulant therapy has been reported frequently in the literature, but only two cases due to ticlopidine and one case due to salicyclate have been reported. We report the case of a 54-year-old man with haemorrhagic shock due to spontaneous splenic haemorrhage and rupture following dual antiplatelet (aspirin and clopidogrel therapy. He was successfully treated with selective angioembolization of the bleeding branch of the splenic artery.

    Full Text Available Cerebral vasospasm is the prolonged, intense constriction of the larger conducting arteries in the subarachnoid space which are initially surrounded by subarachnoid clot. Significant narrowing develops gradually over the first few days after the aneurysmal rupture. The spasm usually is maximal in about a week′s time following haemorrhage. Vasospasm is the one of the leading causes of death after the aneurysmal rupture along with the effect of the initial haemorrhage and latter rebleeding. The purpose of this article is to outline the importance in early diagnosis and aggressive treatment of this otherwise challenging clinical entity.

    Full Text Available Abstract Background It is widely accepted that infants at risk for cerebral palsy need paediatric physiotherapy. However, there is little evidence for the efficacy of physiotherapeutic intervention. Recently, a new intervention program, COPCA (Coping with and Caring for infants with special needs - a family centered program, was developed. COPCA has educational and motor goals. A previous study indicated that the COPCA-approach is associated with better developmental outcomes for infants at high risk for developmental disorders. LEARN 2 MOVE 0-2 years evaluates the efficacy and the working mechanisms of the COPCA program in infants at very high risk for cerebral palsy in comparison to the efficacy of traditional infant physiotherapy in a randomized controlled trial. The objective is to evaluate the effects of both intervention programs on motor, cognitive and daily functioning of the child and the family and to get insight in the working elements of early intervention methods. Methods/design Infants are included at the corrected age of 1 to 9 months and randomized into a group receiving COPCA and a group receiving traditional infant physiotherapy. Both interventions are given once a week during one year. Measurements are performed at baseline, during and after the intervention period and at the corrected age of 21 months. Primary outcome of the study is the Infant Motor Profile, a qualitative evaluation instrument of motor behaviour in infancy. Secondary measurements focus on activities and participation, body functions and structures, family functioning, quality of life and working mechanisms. To cope with the heterogeneity in physiotherapy, physiotherapeutic sessions are video-recorded three times (baseline, after 6 months and at the end of the intervention period. Physiotherapeutic actions will be quantified and related to outcome. Discussion LEARN 2 MOVE 0-2 years evaluates and explores the effects of COPCA and TIP. Whatever the outcome of

    Our objective was to determine whether continuous transcranial Doppler (TCD) monitoring could safely enhance the efficacy of batroxobin, a thrombin-like enzyme extracted from Bothrops atrox moojeni venom, in the treatment for acute cerebral stroke beyond the thrombolytic time window. Ninety patients suffering an acute cerebral stroke were recruited into the study within 12 hours after the onset of symptoms. Patients were randomized to receive batroxobin with (target group) or without 1 hour of continuous TCD monitoring (control group). Clinical evaluation of stroke was based on the National Institutes of Health Stroke Scale (NIHSS) score, Barthel index (BI), Thrombolysis in Brain Ischemia score (TIBI), the incidence of advancing stroke, and the recurrence of cerebral infarction. The patients receiving continuous TCD monitoring showed significant improvement in NIHSS score at 57 days post treatment compared with the control. Similarly, patients receiving continuous TCD monitoring also showed significant improvement in BI at 3 months compared with the controls. Consistently, both the incidence of advancing stroke after 1 week and the incidence of stroke recurrence after 3 months were significantly lower in TCD monitored group than control group. Moreover, the safety of the employment of TCD monitoring in the treatment of these patients was confirmed as there was no significant difference of the incidence of intracranial hemorrhage at 1 week after the treatment between the target and control groups. Taken together, our study showed that batroxobin, in combination with continuous TCD monitoring at the middle cerebral artery, reduced the incidence of advancing stroke and stroke recurrence after treatment without adverse effects in terms of poststroke intracranial hemorrhage.

    [Purpose] Improved gait efficiency is one of the goals of therapy for children with cerebral palsy (CP). Postural insoles can allow more efficient gait by improving biomechanical alignment. The aim of the present study was to assess the effect of postural insoles on gait performance of children with CP classified as levels I or II of the Gross Motor Function Classification System (GMFCS). [Subjects and Methods] the study was a randomized controlled double-blind clinical trial. After meeting the legal aspects and the eligibility criteria, 10 children between four and 12 years old were randomly divided into a two groups: a control group (n=5), and an experimental group (n=5). Children in the control group used a placebo insoles, and children in the experimental group used postural insoles. Evaluation consisted of three-dimensional gait analysis under three conditions: barefoot, shoes without insoles and shoes with postural insoles or shoes with placebo insoles. [Results] Regarding the immediate effects of insole use, significant improvements in gait velocity and cadence were observed in the experimental group in comparison to the control group. [Conclusion] The use of postural insoles led to improvements in gait velocity and cadence of the children with cerebral palsy classified as levels I or II of the GMFCS.

    Full Text Available Though the cause of motor abnormalities in cerebral palsy is injury to the brain, structural changes in muscle and fascia may add to stiffness and reduced function. This study examined whether Myofascial Structural Integration therapy (MSI, a complementary treatment that manipulates muscle and fascia, would improve gross motor function and gait in children < 4 years with cerebral palsy. Participants (N=29 were enrolled in a randomized controlled trial (RCT: NCT01815814, https://goo.gl/TGxvwd or Open Label Extension. The main outcome was the Gross Motor Function Measure-66 assessed at 3-month intervals. Gait (n=8 was assessed using the GAITRite® electronic walkway. Parents completed a survey at study conclusion.Comparing Treatment (n=15 and Waitlist-Control Groups (n=9, we found a significant main effect of time but no effect of group or timeXgroup interaction. The pooled sample (n=27 showed a main effect of time, but no significantly greater change after treatment than between other assessments. Foot length on the affected side increased significantly after treatment, likely indicating improvement in the children’s ability to approach a heel strike. Parent surveys indicated satisfaction and improvements in the children's quality of movement. MSI did not increase the rate of motor skill development, but was associated with improvement in gait quality.

    2007-03-01

    Full Text Available Abstract Background In the past, effortful exercises were considered inappropriate for children with spastic cerebral palsy (CP due to concern that they would escalate abnormalities including spasticity and abnormal movement patterns. Current scientific evidence indicates that these concerns were unfounded and that therapeutic interventions focused on muscle strengthening can lead to improved functional ability. However, few studies have examined the potential benefits of cardiorespiratory fitness exercises in this patient population. Methods/design The rationale and design of a randomized controlled trial examining the effects of a stationary cycling intervention for children with CP are outlined here. Sixty children with spastic diplegic CP between the ages of 7 and 18 years and Gross Motor Function Classification System (GMFCS levels of I, II, or III will be recruited for this study. Participants will be randomly assigned to either an intervention (cycling or a control (no cycling group. The cycling intervention will be divided into strengthening and cardiorespiratory endurance exercise phases. During the strengthening phase, the resistance to lower extremity cycling will be progressively increased using a uniquely designed limb-loaded mechanism. The cardiorespiratory endurance phase will focus on increasing the intensity and duration of cycling. Children will be encouraged to exercise within a target heart rate (HR range (70 – 80% maximum HR. Thirty sessions will take place over a 10–12 week period. All children will be evaluated before (baseline and after (follow-up the intervention period. Primary outcome measures are: knee joint extensor and flexor moments, or torque; the Gross Motor Function Measure (GMFM; the 600 Yard Walk-Run test and the Thirty-Second Walk test (30 sec WT.

    Full Text Available Abstract Background Regular participation in physical activities is important for all children to stay fit and healthy. Children with cerebral palsy have reduced levels of physical activity, compared to typically developing children. The aim of the LEARN 2 MOVE 7-12 study is to improve physical activity by means of a physical activity stimulation program, consisting of a lifestyle intervention and a fitness training program. Methods/Design This study will be a 6-month single-blinded randomized controlled trial with a 6-month follow up. Fifty children with spastic cerebral palsy, aged 7 to 12 years, with Gross Motor Function Classification System levels I-III, will be recruited in pediatric physiotherapy practices and special schools for children with disabilities. The children will be randomly assigned to either the intervention group or control group. The children in the control group will continue with their regular pediatric physiotherapy, and the children in the intervention group will participate in a 6-month physical activity stimulation program. The physical activity stimulation program consists of a 6-month lifestyle intervention, in combination with a 4-month fitness training program. The lifestyle intervention includes counseling the child and the parents to adopt an active lifestyle through Motivational Interviewing, and home-based physiotherapy to practise mobility-related activities in the daily situation. Data will be collected just before the start of the intervention (T0, after the 4-month fitness training program (T4, after the 6-month lifestyle intervention (T6, and after six months of follow-up (T12. Primary outcomes are physical activity, measured with the StepWatch Activity Monitor and with self-reports. Secondary outcomes are fitness, capacity of mobility, social participation and health-related quality of life. A random coefficient analysis will be performed to determine differences in treatment effect between the control

    Full Text Available There has been little research on bathroom accidents. It is unknown whether the shower or bathtub are connected with special dangers in different age groups or whether there are specific risk factors for adverse outcomes.This cross-sectional analysis included all direct admissions to the Emergency Department at the Inselspital Bern, Switzerland from 1 January 2000 to 28 February 2014 after accidents associated with the bathtub or shower. Time, age, location, mechanism and diagnosis were assessed and special risk factors were examined. Patient groups with and without intracranial bleeding were compared with the Mann-Whitney U test.The association of risk factors with intracranial bleeding was investigated using univariate analysis with Fisher's exact test or logistic regression. The effects of different variables on cerebral bleeding were analysed by multivariate logistic regression.Two hundred and eighty (280 patients with accidents associated with the bathtub or shower were included in our study. Two hundred and thirty-five (235 patients suffered direct trauma by hitting an object (83.9% and traumatic brain injury (TBI was detected in 28 patients (10%. Eight (8 of the 27 patients with mild traumatic brain injuries (GCS 13-15, (29.6% exhibited intracranial haemorrhage. All patients with intracranial haemorrhage were older than 48 years and needed in-hospital treatment. Patients with intracranial haemorrhage were significantly older and had higher haemoglobin levels than the control group with TBI but without intracranial bleeding (p<0.05 for both.In univariate analysis, we found that intracranial haemorrhage in patients with TBI was associated with direct trauma in general and with age (both p<0.05, but not with the mechanism of the fall, its location (shower or bathtub or the gender of the patient. Multivariate logistic regression analysis identified only age as a risk factor for cerebral bleeding (p<0.05; OR 1.09 (CI 1.01;1.171.In patients

    2015-04-01

    Spontaneous Idiopathic Adrenal Haemorrhage (SIAH) is an unusual surgical emergency which can present with life threatening massive retroperitoneal bleeding. Most of the cases reported in the literature are associated with use of anticoagulation or underlying adrenal pathology such as tumors or cysts. Since this clinical entity is uncommon and clinical presentation is very indistinct, the diagnosis can be easily missed and can be challenging for the treating physicians. Nevertheless a raised clinical suspicion coupled with advances in radiological imaging have considerably improved the detection of SIAH in recent times. We report an unusual case of a 20 years old healthy female student who presented to our hospital with sudden onset of abdominal pain and shock. She was diagnosed as a case of massive spontaneous idiopathic unilateral adrenal haemorrhage, unaccompanied by any hematologic disorder, trauma or underlying pathology. Although patient was hemodynamically unstable at presentation, she was resuscitated promptly, investigated appropriately, hence recovered uneventfully with conservative management alone.

    Standard imaging in acute stroke enables the exclusion of non-stroke structural CNS lesions and cerebral haemorrhage from clinical and pre-clinical ischaemic stroke trials. In this review, the potential benefit of imaging (e.g., angiography and penumbral imaging) as a translational tool for trial recruitment and the use of imaging endpoints are discussed for both clinical and pre-clinical stroke research. The addition of advanced imaging to identify a "responder" population leads to reduced sample size for any given effect size in phase 2 trials and is a potentially cost-efficient means of testing interventions. In pre-clinical studies, technical failures (failed or incomplete vessel occlusion, cerebral haemorrhage) can be excluded early and continuous multimodal imaging of the animal from stroke onset is feasible. Pre- and post-intervention repeat scans provide real time assessment of the intervention over the first 4-6 h. Negative aspects of advanced imaging in animal studies include increased time under general anaesthesia, and, as in clinical studies, a delay in starting the intervention. In clinical phase 3 trial designs, the negative aspects of advanced imaging in patient selection include higher exclusion rates, slower recruitment, overestimated effect size and longer acquisition times. Imaging may identify biological effects with smaller sample size and at earlier time points, compared to standard clinical assessments, and can be adjusted for baseline parameters. Mechanistic insights can be obtained. Pre-clinically, multimodal imaging can non-invasively generate data on a range of parameters, allowing the animal to be recovered for subsequent behavioural testing and/or the brain taken for further molecular or histological analysis.

    Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post—resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during ventricular fibrillation cardiac arrest (VF-CA) and ECLS versus conventional CPR. Male Sprague-Dawley rats (350g) underwent 8min untreated VF-CA followed by ECLS (n = 8; bloodflow 100ml/kg), mechanical CPR (n = 18; 200/min) until return of spontaneous circulation (ROSC). Shams (n = 2) were included. Glucose, glutamate and lactate/pyruvate ratio were compared between treatment groups and animals with and without ROSC. Ten animals (39%) achieved ROSC (ECLS 5/8 vs. CPR 5/18; OR 4,3;CI:0.7–25;p = 0.189). During VF-CA central nervous glucose decreased (0.32±0.1mmol/l to 0.04±0.01mmol/l; p<0.001) and showed a significant rise (0.53±0.1;p<0.001) after resuscitation. Lactate/pyruvate (L/P) ratio showed a 5fold increase (31 to 164; p<0.001; maximum 8min post ROSC). Glutamate showed a 3.5-fold increase to (2.06±1.5 to 7.12±5.1μmol/L; p<0.001) after CA. All parameters normalized after ROSC with no significant differences between ECLS and CPR. Metabolic changes during ischemia and resuscitation can be displayed by cerebral microdialysis in our VF-CA CPR and ECLS rat model. We found similar microdialysate concentrations and patterns of normalization in both resuscitation methods used. Institutional Protocol Number: GZ0064.11/3b/2011 PMID:27175905

    Full Text Available To investigate changes of muscle recruitment and coordination following constraint-induced movement therapy, constraint-induced movement therapy plus electrical stimulation, and traditional occupational therapy in treating hand dysfunction.In a randomized, single-blind, controlled trial, children with hemiplegic cerebral palsy were randomly assigned to receive constraint-induced movement therapy (n = 22, constraint-induced movement therapy plus electrical stimulation (n = 23, or traditional occupational therapy (n = 23. Three groups received a 2-week hospital-based intervention and a 6-month home-based exercise program following hospital-based intervention. Constraint-induced movement therapy involved intensive functional training of the involved hand during which the uninvolved hand was constrained. Electrical stimulation was applied on wrist extensors of the involved hand. Traditional occupational therapy involved functional unimanual and bimanual training. All children underwent clinical assessments and surface electromyography (EMG at baseline, 2 weeks, 3 and 6 months after treatment. Surface myoelectric signals were integrated EMG, root mean square and cocontraction ratio. Clinical measures were grip strength and upper extremity functional test.Constraint-induced movement therapy plus electrical stimulation group showed both a greater rate of improvement in integrated EMG of the involved wrist extensors and cocontraction ratio compared to the other two groups at 3 and 6 months, as well as improving in root mean square of the involved wrist extensors than traditional occupational therapy group (p<0.05. Positive correlations were found between both upper extremity functional test scores and integrated EMG of the involved wrist as well as grip strength and integrated EMG of the involved wrist extensors (p<0.05.Constraint-induced movement therapy plus electrical stimulation is likely to produce the best outcome in improving muscle recruitment

    2016-05-01

    Full Text Available Cerebral Palsy (CP results from an insult to the developing brain and is associated with deficits in locomotor and manual skills and in sensorimotor adaptation. We hypothesized that the poor sensorimotor adaptation in persons with CP is related to their high execution variability and does not reflect a general impairment in adaptation learning. We studied the interaction between performance variability and adaptation deficits using a multi-session locomotor adaptation design in persons with CP. Six adolescents with diplegic CP were exposed, during a period of 15 weeks, to a repeated split-belt treadmill perturbation spread over 30 sessions and were tested again 6 months after the end of training. Compared to age-matched healthy controls, subjects with CP showed poor adaptation and high execution variability in the first exposure to the perturbation. Following training they showed marked reduction in execution variability and an increase in learning rates. The reduction in variability and the improvement in adaptation were highly correlated in the CP group and were retained 6 months after training. Interestingly, despite reducing their variability in the washout phase, subjects with CP did not improve learning rates during washout phases that were introduced only 4 times during the experiment. Our results suggest that locomotor adaptation in subjects with CP is related to their execution variability. Nevertheless, while variability reduction is generalized to other locomotor contexts, the development of savings requires both reduction in execution variability and multiple exposures to the perturbation.

    2008-10-01

    Full Text Available Abstract Background Until recently, strength training in children with cerebral palsy (CP was considered to be inappropriate, because it could lead to increased spasticity or abnormal movement patterns. However, the results of recent studies suggest that progressive strength training can lead to increased strength and improved function, but low methodological quality and incomplete reporting on the training protocols hampers adequate interpretation of the results. This paper describes the design and training protocol of a randomized controlled trial to assess the effects of a school-based progressive functional strength training program for children with CP. Methods/Results Fifty-one children with Gross Motor Function Classification Systems levels I to III, aged of 6 to 13 years, were recruited. Using stratified randomization, each child was assigned to an intervention group (strength training or a control group (usual care. The strength training was given in groups of 4–5 children, 3 times a week, for a period of 12 weeks. Each training session focussed on four exercises out of a 5-exercise circuit.

To evaluate the effectiveness of the training, all children were evaluated before, during, directly after, and 6 weeks after the intervention period. Primary outcomes in this study were gross motor function (measured with the Gross Motor Function Measure and functional muscle strength tests and walking ability (measured with the 10-meter, the 1-minute and the timed stair test. Secondary outcomes were lower limb muscle strength (measured with a 6 RM test, isometric strength tests, and a sprint capacity test, mobility (measured with a mobility questionnaire, and sport activities (measured with the Children's Assessment of Participation and Enjoyment.

    Patient outcomes following grade V subarachnoid haemorrhage (SAH) have been dismal, although they may have improved following recent technological advances in endovascular treatment (EVT). A single-centre, retrospective study was conducted to evaluate whether outcomes have improved from 2000 to 2014 for patients with World Federation of Neurosurgical Societies (WFNS) grade V SAH. Coiling has been the preferred first-line treatment for grade V SAH patients in our institution since 2000. Patients who underwent EVT (n=115) were grouped on the basis of their hospital admission year: 2000-2004 (n=44), 2005-2009 (n=37) and 2010-2014 (n=34). Patient demographics, outcomes and in-hospital mortality rates were compared between the groups. Patient outcomes at discharge were evaluated using the Glasgow Outcome Scale (GOS), with GOS scores of 4-5 defined as favourable outcomes. There were no significant intergroup differences in patient demographics. In addition, there were no significant differences in the frequencies of favourable outcomes (14% in 2000-2004, 16% in 2005-2009 and 26% in 2010-2014). Mortality rates were 52% in 2000-2004, 43% in 2005-2009 and 24% in 2010-2014, with a significantly lower mortality rate in 2010-2014 than in 2000-2004 (p=0.01). Both perioperative rebleeding and delayed cerebral ischaemia decreased over time; however, multivariate regression analysis showed that the former contributed more to the decrease in mortality. Age was the only variable associated with favourable outcomes. The results of this study indicate that EVT is an appropriate therapeutic option for grade V SAH patients. However, multi-centre, prospective trials are required to provide evidence-based verification of the efficacy of EVT.

    Full Text Available A patient with multiple traumas is usually found in severe haemorrhagic shock. In 40% of the cases, the patient with multiple traumas and haemorrhagic shock cannot recover due to secondary injuries and complications associated with the shock. In this paper we present the case of a male patient 30 years old, who suffered a car accident. The patient is admitted in our hospital with haemorrhagic shock due to femur fracture, acute cranial-cerebral trauma and severe thoracic trauma with bleeding scalp wound, associated with lethal triad of trauma. The clinical and biological parameters demand massive transfusion with packed red blood cells (PRBCs, fresh frozen plasma (FFP, cryoprecipitate (CRY and colloidal solution (CO sustained with vassopresor for the haemodynamic stabilisation. During his stay in the ICU, the patient benefits from anti-oxidative therapy with Vitamin C, Vitamin E and Vitamin B1. After 14 days the clinical state of the patient improves and he is transferred in Polytrauma Department.

  18. Experimental thrombolysis of middle cerebral artery thromboemboli

    International Nuclear Information System (INIS)

    Since the majority of ischaemic cerebral infarcts is caused by thromboemboli, we determined the benefit of firbrinolytic therapy in acute stroke. Thromboemboli were induced in the middle cerebral artery of 21 dogs. Urokinase was started at different time intervals after infarction (1, 3 and 5 hours) at a rate of 1000 IU/kg/min. Angiographically controlled thrombolysis was achieved in all 15 treated cases, whereas in the control group (n=6) no case of recanalisation was observed. Systemic fibrinolysis occurred in all cases. Postmortem examinations of the brains showed no intracerebral haemorrhages. Our findings indicate the urokinase treatment may be of value in acute ischaemic stroke. (orig.)

    To better generalize training effects to the context of daily living, home-based constraint-induced therapy has been proposed. Therapeutic success of constraint-induced therapy is limited as to whether the improvements in functional performance can be transferred to quality of life. This randomized controlled trial aimed to investigate the efficacy of home-based constraint-induced therapy on functional performance and health-related quality of life. Twenty-two children with spastic unilateral cerebral palsy (6-8 years, 10 boys) were randomly assigned to receive constraint-induced therapy or traditional rehabilitation. Home-based constraint-induced therapy had immediate and maintaining effects on motor efficacy and functional performance and induced greater gains in health-related quality of life in the long run than in the short term. The home-based constraint-induced therapy protocol (relatively moderate intensity and shortened constraint time), which might balance the effectiveness and compliance of participants and caregivers, may be an effective alternative to conventional constraint-induced therapy.

    2008-11-01

    The relationship of this country with dengue has been long and intense. The first recorded epidemic of clinically dengue-like illness occurred at Madras in 1780 and the dengue virus was isolated for the first time almost simultaneously in Japan and Calcutta in 1943–1944. After the first virologically proved epidemic of dengue fever along the East Coast of India in 1963–1964, it spread to allover the country. The first full-blown epidemic of the severe form of the illness, the dengue haemorrhagic fever/dengue shock syndrome occurred in North India in 1996. Aedes aegypti is the vector for transmission of the disease. Vaccines or antiviral drugs are not available for dengue viruses; the only effective way to prevent epidemic degure fever/dengue haemorrhagic fever (DF/DHF) is to control the mosquito vector, Aedes aegypti and prevent its bite. This country has few virus laboratories and some of them have done excellent work in the area of molecular epidemiology, immunopathology and vaccine development. Selected work done in this country on the problems of dengue is presented here.

    Eleven piglets with haemorrhagic necrotizing pancreatitis and nine piglets with oedematous pancreatitis were imaged using a multi-breath-hold TurboFLASH (TR 6.5 ms, TE 3 ms, TI 300 ms, flip angle 8 , three slices) pre-excited T1-weighted sequence with an IV bolus injection of gadopentetate dimeglumine (Gd-DTPA, 0.3 mmol/kg) as a contrast agent to show dynamic contrast enhancement of the pancreas by MRI. All piglets were imaged according to the same protocol before inducing the disease. Following the IV Gd-DTPA bolus, time-enhancement curve of the pancreas during haemorrhagic necrotizing pancreatitis was significantly lower than during oedematous pancreatitis. The enhancement curves for the healthy piglets and piglets with oedematous pancreatitis did not differ significantly. Each piglet served as its own control. Because the results of this initial study are similar to those obtained with contrast-enhanced CT, we conclude that our results may encourage further clinical trials, and contrast-enhanced dynamic MRI may be an alternative to the established method of CT for diagnosing acute haemorrhagic necrotizing pancreatitis.

    Intracranial lipomas are rare congenital malformations that can often be seen in association with other brain malformations; agenesis or dysgenesis of the corpus callosum is the most frequently associated brain anomaly. They are usually pericallosal asymptomatic midline lesions. Intracranial lipomas associated with a non-contiguous cerebral aneurysm are extremely rare. We report an infant with partial agenesis of the corpus callosum and pericallosal lipoma associated with cerebral haemorrhage due to a distal middle cerebral artery aneurysm. Such an association is probably not fortuitous and could suggest a pathogenic relationship. (orig.)

    Full Text Available BACKGROUND AND PURPOSE To describe the role of Glasgow Coma Scale (GCS as an initial and simple tool of neurological assessment and also haematoma volume in selection of patient for surgery. MATERIALS AND METHODS After an initial GCS assessment, 50 patients with a history of head trauma were referred for a head CT which was done with a GE Bright Speed Elite 16 slice CT scanner. RESULTS 42 patients (84% were males and 8 (16% were females. The mean age was 33.54 years and the maximum numbers of patients affected belonged to the age group of 21 to 30 years. The most common mode of injury in this study was road traffic accident (RTA accounting for 86%. 42% of patients presented with a GCS of haemorrhage. 20 patients in this study were operated, the indication being either SDH or EDH with a volume more than 20 mL and 30 mL respectively. Among intra-axial haemorrhages, cerebral contusions were the commonest type encountered with 34 out of 50 patients that is 68%. DAI was the other less common type of intra-axial haemorrhage accounting for 6%. Patients were selected for surgery based on the admission GCS and haematoma volume as determined using Petersen and Esperson formula on the CT images. Both GCS score and haematoma volume assessment were most crucial indicators for the surgical management of the patients in this study. Immediate surgery for patients with large haematomas was associated with positive outcome. CONCLUSIONS It was concluded that the initial GCS score played a major role in quick and reliable assessment of neurological status of the patient. The GCS score also correlated with the haematoma volume as seen on the CT. Both GCS score and haematoma volume assessment were most crucial indicators for the surgical management of the patients in this study.

  11. Procedure-related haemorrhage in embolisation of intracranial aneurysms with Guglielmi detachable coils

    International Nuclear Information System (INIS)

    We reviewed the haemorrhagic complications of the endovascular treatment of intracranial aneurysms, in terms of frequency, pre-embolisation clinical status, clinical and radiological manifestations, management and prognosis. In 275 patients treated for 303 aneurysms over 7 years we had seven (one man and six women - 2.3%) with haemorrhage during or immediately after endovascular treatment. All procedures were performed with a standardised protocol of heparinisation and anaesthesia. Four had ruptured aneurysms, two at the tip of the basilar artery, and one ach on the internal carotid and posterior cerebral artery, treated after 12, 5, 14, and 2 days, respectively, three were in Hunt and Hess grade 2 and one in grade 1. Bleeding occurred during coiling in three, after placement of at least four coils, and during manipulation of the guidewire to enter the aneurysm in the fourth. Haemorrhage was manifest as extravasation of contrast medium, with a sudden rise in systolic blood pressure in three patients. The other three patients had unruptured aneurysms; they had stable blood pressure and angiographic findings during the procedure, but one, under sedation, had seizures immediately after insertion of four coils, and the other two had seizures, headache and vomiting on the day following the procedure. Heparin reversal with protamine sulphate was started promptly started when bleeding was detected in four patients, and the embolisation was completed with additional coils in three. Emergency ventricular drainage was performed in the two patients with ruptured aneurysm and one with an unruptured aneurysm who had abnormal neurological responses or hydrocephalus. The bleeding caused a third nerve palsy in one patient, which might have been due to ischaemia and progressively improved. (orig.)

    Spontaneous intracerebral haemorrhage (ICH) is one of the most devastating types of stroke, which has considerable disease burden in "non-white" ethnic groups where the population-attributable risks of elevated blood pressure are very high. Since the treatment of ICH remains largely supportive and expectant, nihilism and the early withdrawal of active therapy influence management decisions in clinical practice. However, approaches to management are now better defined on the basis of evidence that both survival and speed (and degree) of recovery are critically dependent on the location, size, and degree of expansion and extension into the intraventricular system of the haematoma of the ICH. Although no medical treatment has been shown to improve outcome in ICH, several promising avenues have emerged that include haemostatic therapy and intensive control of elevated blood pressure. Conversely, there is continued controversy over the role of evacuation of the haematoma of ICH via open craniotomy. Despite being an established practice for several decades, and having undergone evaluation in multiple randomised trials, there is uncertainty over which patients have the most to gain from an intervention with clear procedural risk. Minimally invasive surgery via local anaesthetic applied drill-puncture of the cranium and infusion of a thrombolytic agent is an attractive option for patients requiring critical management of the haematoma, not just in low resource settings but arguably also in specialist centres of western countries. With several ongoing clinical trials nearing completion, these treatments could enter routine practice within the next few years, further justifying the urgency of "time is brain" and that active management within well-organized, comprehensive acute stroke care units includes patients with ICH.

    Hereditary haemorrhagic telangiectasia(HHT) is an autosomal dominant inherited disorder characterised by vascular malformations in predominantly the brain,liverand lungs.Pulmonary hypertension(PH) is increasingly recognised as a severe complication of HHT.PH may be categorised into two distinct types in patients with HHT.Post-capillary PH most often results from a high pulmonary blood flow that accompanies the high cardiac output state associated with liver arteriovenous malformations.Less frequently,the HHT-related gene mutations in ENG or ACVRL1 appear to predispose patients with HHT to develop pre-capillary pulmonary arterial hypertension.Differentiation between both forms of PH by right heart catheterisation is essential,since both entities are associated with severe morbidity and mortality with different treatment options.Therefore all HHT patients should be referred to an HHT centre.

    Radiation-induced severe haemorrhagic cystitis is difficult to treat. Conventional treatments may decrease haematuria but do not affect the radiocystitis itself. Hyperbaric oxygen treatment has been reported to do both. We report the results of a prospective study of hyperbaric oxygen (20 sessions of 100% oxygen inhalation at 3 bar for 90 min in a multiplace hyperbaric chamber) to 40 patients with biopsy-proven radiation cystitis and severe haematuria. Haematuria disappeared completely or improved in 37 patients after treatment. Mean follow-up was 23.1 months (range 1-74); and the recurrence rate was 0.12/year. There were no adverse effects. Hyperbaric oxygen treatment should be considered for patients with severe radiation-induced haematuria. (author).

  17. Filoviral haemorrhagic fevers: A threat to Zambia?

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Filoviral haemorrhagic fevers (FVHF are caused by agents belonging to Filoviridae family, Ebola and Marburg viruses. They are amongst the most lethal pathogens known to infect humans. Incidence of FVHF outbreaks are increasing, with affected number of patients on the rise. Whilst there has been no report yet of FVHF in Zambia, its proximity to Angola and Democratic Republic of Congo, which have recorded major outbreaks, as well as the open borders, increased trade and annual migration of bats between these countries, puts Zambia at present and increased risk. Previous studies have indicated bats as potential reservoir hosts for filoviruses. An increasing population with an increasing demand for resources has forced incursion into previously uninhabited land, potentially bringing them into contact with unknown pathogens, reservoir hosts and/or amplifying hosts. The recent discovery of a novel arenavirus, Lujo, highlights the potential that every region, including Zambia, has for being the epicentre or primary focus for emerging and re-emerging infections. It is therefore imperative that surveillance for potential emerging infections, such as viral haemorrhagic fevers be instituted. In order to accomplish this surveillance, rapid detection, identification and monitoring of agents in patients and potential reservoirs is needed. International co-operation is the strategy of choice for the surveillance and fight against emerging infections. Due to the extensive area in which filoviral infections can occur, a regional approach to surveillance activities is required, with regional referral centres. There is a need to adopt shared policies for the prevention and control of infectious diseases. There is also need for optimisation of currently available tests and development of new diagnostic tests, in order to have robust, highly sensitive and specific diagnostic tests that can be used even where there are inadequate laboratories and diagnostic services.

    Hereditary Haemorrhagic Telangiectasia (HHT) or Rendu-Osler-Weber syndrome, is an autosomal dominant rare disease characterized by localized angiodysplasia. This is manifested as epistaxis, mucocutaneous and gastrointestinal telangiectases, and arteriovenous malformations in the pulmonary, cerebral or hepatic circulation. The prevalence is between 1 in 5,000 to 8,000, although it is higher in some regions. The most frequent clinical manifestation of HHT is epistaxis, normally from light to moderate from the 4(th) decade of life. However, many patients show severe epistaxis which may interfere with their quality of life. The epistaxis is due to telangiectasia on the nasal mucosa. These are focally dilated postcapilar venules, which in advanced phases show many layers of smooth muscle cells without elastic fibers, and very frequently directly connect with dilated arterioles. As a consequence of these vascular alterations, telangiectases are very sensitive to slight trauma and even to the friction with the air when breathing, which gives rise to nose bleeds. Unfortunately, there is no optimal pharmacological treatment for the epistaxis in HHT. The use of antifibrinolytic agents for the treatment of HHT has been studied recently by our group as an effective relief for nasal and gastric haemorrhages. This work represents a systematic review and the beginning of a systematic laboratory work we are now conducting in our lab to screen for "orphan drugs" as therapeutic agents in HHT. In this context, the use of hormones, immunosuppresants and anti-angiogenic agents are under preclinical study in our laboratory. PMID:19485912

  20. Intracerebral haemorrhage in Down syndrome: protected or predisposed? [version 1; referees: 2 approved

    Full Text Available Down syndrome (DS, which arises from trisomy of chromosome 21, is associated with deposition of large amounts of amyloid within the central nervous system. Amyloid accumulates in two compartments: as plaques within the brain parenchyma and in vessel walls of the cerebral microvasculature. The parenchymal plaque amyloid is thought to result in an early onset Alzheimer’s disease (AD dementia, a phenomenon so common amongst people with DS that it could be considered a defining feature of the condition. The amyloid precursor protein (APP gene lies on chromosome 21 and its presence in three copies in DS is thought to largely drive the early onset AD. In contrast, intracerebral haemorrhage (ICH, the main clinical consequence of vascular amyloidosis, is a more poorly defined feature of DS. We review recent epidemiological data on stroke (including haemorrhagic stroke in order to make comparisons with a rare form of familial AD due to duplication (i.e. having three copies of the APP region on chromosome 21, here called ‘dup-APP’, which is associated with more frequent and severe ICH. We conclude that although people with DS are at increased risk of ICH, this is less common than in dup-APP, suggesting the presence of mechanisms that act protectively. We review these mechanisms and consider comparative research into DS and dup-APP that may yield further pathophysiological insight.

    Full Text Available Abstract Background Use of Botulinum toxin-A (BoNT-A for treatment of upper limb spasticity in children with cerebral palsy has become routine clinical practice in many paediatric treatment centres worldwide. There is now high-level evidence that upper limb BoNT-A injection, in combination with occupational therapy, improves outcomes in children with cerebral palsy at both the body function/structure and activity level domains of the International Classification of Functioning, Disability and Health. Investigation is now required to establish what amount and specific type of occupational therapy will further enhance functional outcomes and prolong the beneficial effects of BoNT-A. Methods/Design A randomised, controlled, evaluator blinded, prospective parallel-group trial. Eligible participants were children aged 18 months to 6 years, diagnosed with spastic hemiplegic cerebral palsy and who were able to demonstrate selective motor control of the affected upper limb. Both groups received upper limb injections of BoNT-A. Children were randomised to either the modified constraint-induced movement therapy group (experimental or bimanual occupational therapy group (control. Outcome assessments were undertaken at pre-injection and 1, 3 and 6 months following injection of BoNT-A. The primary outcome measure was the Assisting Hand Assessment. Secondary outcomes included: the Quality of Upper Extremity Skills Test; Pediatric Evaluation of Disability Inventory; Canadian Occupational Performance Measure; Goal Attainment Scaling; Pediatric Motor Activity Log; modified Ashworth Scale and; the modified Tardieu Scale. Discussion The aim of this paper is to describe the methodology of a randomised controlled trial comparing the effects of modified constraint-induced movement therapy (a uni-manual therapy versus bimanual occupational therapy (a bimanual therapy on improving bimanual upper limb performance of children with hemiplegic cerebral palsy following

    The association of cerebral dural arteriovenous fistula (DAVF) and ipsilateral flow related aneurysm has infrequently been reported. We describe a male patient who presented with an acute haemorrhagic stroke and was found to have a large right fronto-parietal intra-parenchymal haemorrhage from the ruptured Borden type II DAVF in addition to a large venous aneurysm and a flow related intraosseous aneurysm of the contralateral middle meningeal artery (MMA) all clearly delineated by CT and DSA. He underwent emergency stereotactic evacuation of the intraparenchymal haemorrhage and successful surgical treatment of all the vascular lesions at the same time with residual neurological deficit. To our knowledge, this is the first such reported case. We discuss the challenging surgical treatment, emphasising the role of CT/DSA in management, and provide a literature review.

    Increased natriuresis is a frequent situation after subarachnoid haemorrhage (SAH). It may be responsible for hyponatremia, which can be dangerous in case of severe hypo-osmolarity or hypovolemia. Inappropriate secretion of antidiuretic hormone or cerebral salt wasting syndrome (CSWS) have been incriminated for hyponatremia after SAH, but it remains difficult to distinguish between both syndromes. There are many explanations for increased natriuresis after SAH, depending on the level of blood pressure, the volemia, and the presence or not of natriuretic peptides. The cerebral insult and the treatments, which are done to fight against elevated intracranial pressure or vasospasm, can modify any of these parameters. So it appears that the word "cerebral" in CSWS is probably not a good term and it would be better to talk about appropriate or non-appropriate natriuretic response. Corticoïds or urea can be useful for controlling hypernatriuresis.

    Full Text Available La malaria Cerebral (MC es la complicación más frecuente de la malaria por P. falciparum; aproximadamente el 90% de las personas que la han padecido se recuperan completamente sin secuelas neurológicas. Aún no se conoce con claridad su patogénesis pero se han postulado cuatro hipótesis o mecanismos posibles: 1 citoadherencia y secuestro de glóbulos rojos parasitados en la microvasculatura cerebral; 2 formación de rosetas y aglutinación de glóbulos rojos parasitados; 3 producción de citoquinas y activación de segundos mensajeros y, 4 apertura de la barrera hematoencefálica. Sin embargo, queda un interrogante sin resolver aún: ¿qué proceso se lleva a cabo para que el parásito, desde el espacio microvascular, pueda interferir transitoriamente con la función cerebral? Recientemente se ha utilizado el precursor de la proteína b-Amiloide como un marcador de daño neuronal en MC; este precursor será de gran ayuda en futuras investigaciones realizadas en nuestro medio que aporten información para comprender la patogénesis de la MC. Is the most common complication of P. falciparum malaria; nearly 90% of people who have suffered CM can recover without neurological problems. Currently there are four hypotheses that explain pathogenesis of CM: cytoadherence and sequestering of parasitized red blood cells to cerebral capillaries; rosette formation and parasitized red blood cells agglutination; production of cytokines and activation of second messengers and opening of the blood-brain barrier. However the main question remains to be answered; how the host-parasite interaction in the vascular space interferes transiently with cerebral function? Recently, the beta amyloid precursor peptide has been employed as marker of neural injury in CM. It is expected that the beta amyloid precursor peptide will help to understand the pathogenesis of CM in complicated patients of endemic areas of Colombia.

    Subependymal germinal matrix haemorrhage and intraventricular haemorrhage (GMIVH) is a common complication of delivery in preterm neonates but has rarely been observed in the fetus. We report two cases of GMIVH in fetuses of 36 weeks gestation, clearly demonstrated by antenatal MRI. In both cases progressive ventriculomegaly was observed, and ventriculoperitoneal shunts were placed at 19 and 6 months of age, respectively. Prenatal GMIVH may be a cause of congenital hydrocephalus, for which no aetiology has yet been found. (orig.)

  12. Postpartum haemorrhage: a preventable cause of maternal mortality

    International Nuclear Information System (INIS)

    To assess the preventable predictors of severe postpartum haemorrhage and the adverse outcome associated with it. All the admitted patients who developed severe postpartum haemorrhage (>1500 ml) were included in the study. Clinical and sociodemographic data was obtained along with results of investigations to categorize the complications encountered. Odds ratio (OR) and 95% confidence intervals were determined. During the study period, 75 out of 4683 obstetrical admissions, developed severe postpartum haemorrhage (1.6 %). About 65% of the patients were admitted with some other complications including obstructed labour, antepartum haemorrhage and eclampsia. The risk factors were grand multiparity (OR=3.4), pre-eclampsia (OR=2.75), antepartum haemorrhage (OR=13.35), active labour of more than 10 hours (OR=46.92), twin delivery (OR=3.25), instrumental delivery (OR=8.62) and caesarean section (OR=9.74). Maternal mortality in these cases was 2.66% and residual morbidity being 40%. Birth attendant other than doctor and delivery outside the study unit were significantly associated with the adverse outcome in these patients. Maternal outcome associated with postpartum haemorrhage is a function of care given during labour and postnatal period with early diagnosis and management of the complication and its risk factors, being the key of good maternal outcome.

    From its inception the success of liver transplantation has been associated with massive blood loss. Massive transfusion is classically defined as > 10 units of red blood cells within 24 h, but describing transfusion rates over a shorter period of time may reduce the potential for survival bias. Both massive haemorrhage and transfusion are associated with increased risk of mortality and morbidity (need for dialysis/surgical site infection) following liver transplantation although causality is difficult to prove due to the observational design of most trials. The blood loss associated with liver transplantation is multifactorial. Portal hypertension secondary to cirrhosis results in extensive collateral circulation, which can bleed during hepatectomy particular if portal pressures are increased. Avoiding volume loading and maintenance of a low central venous pressure together with the use of vasopressors have been shown to reduce blood loss and transfusion during liver transplantation, but may increase the risk of renal impairment post-operatively. Coagulation defects may be present pre-transplant, but haemostasis is often re-balanced due to a deficit in both pro- and anti-coagulation factors. Further derangement of haemostasis may develop in the anhepatic and neohepatic phases due to absent hepatic metabolic function, hyperfibrinolysis and platelet sequestration in the donor liver. Point-of-care tests of coagulation such as the viscoelastic tests rotation thromboelastometry/thromboelastometry allow and more accurate and rapid assessment of these derangements in coagulation and guide the use of factor replacement and antifibrinolytics. Transfusion protocols guided by these tests have been shown to reduce transfusion rates compared with conventional coagulation tests, but have not shown improvements in mortality or morbidity. Pre-operative factors associated with massive transfusion include previous surgery, re-do transplantation, the aetiology and severity of liver

    Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy. PMID:16391455

    Treatment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) remains a major therapeutic challenge. Systemic drug administration is the current treatment of choice, but patients often do not respond beneficially to this approach. Intrathecal (IT) drug administration has several anatomic and pharmacodynamic advantages over conventional systemic treatment of cerebral vasospasm. We reviewed the most recent literature describing IT administration of several drugs to treat aneurysm-induced SAH and cerebral vasospasm, including 16 clinical trials using IT fibrinolytic agents and 10 trials using several IT vasodilators. We evaluated the safety and effectiveness of these trials but made no attempt to perform a meta-analysis using these data. IT drug administration of fibrinolytic agents and vasodilators caused lysis of the subarachnoid clot burden and diminished cerebral vasospasm, respectively. The studies reviewed reported a wide range of drug doses, intervals between aneurysm hemorrhage and initiation of treatment, success of clot dissolution, and degree of vasodilation of vessels in vasospasm. Treatment of vasospasm by IT drug administration is safe and largely effective after the aneurysm has been secured. Our findings indicate that IT treatment effectively delivers a higher drug concentration to vessels in vasospasm with minimal systemic effects. Drugs administered by this route are reported to lyse subarachnoid clots, attenuate cerebral vasospasm, improve clinical outcomes, and decrease the incidence of hydrocephalus. With greater understanding of drug pharmacodynamics, the IT route of drug administration may provide a rational, alternative approach to treating aneurysm-induced cerebral vasospasm. PMID:22651990

    Full Text Available Crimean-Congo Hemorrhagic Fever (CCHF is an acute, highly-contagious and life-threatening vector borne disease. The CCHF virus causes severe viral hemorrhagic fever outbreaks, with a case fatality rate of 10-40%. CCHF virus isolation and/or disease has been reported from more than 30 countries in Africa, Asia, South eastern Europe and Middle east. Jan 2011 marks first ever reports of outbreak of CCHF in India, total 5 cases were detected of CCHF from Gujarat. CCHF has recently in news again, 6 human cases and 32 animal samples test positive for CCHF from Kariyana village of Amreli district (Gujarat state July 2013. Crimean-Congo hemorrhagic fever virus (CCHFV, member of genus Nairovirus in the family Bunyaviridae. Numerous genera of ixodid ticks serve both as vector and reservoir for CCHFV. Human infections occurred through tick bites, direct contact with blood or tissue of infected livestock, or nosocomial infections. Human infections begin with nonspecific febrile symptoms, but progress to a serious hemorrhagic syndrome with a high case fatality ratio. The most definitive way of diagnosis is the demonstration of virus or viral genome in sera samples. Hospitalization in special care unit with constant effort to prevent haemorrhagic complication along with laboratory monitoring is cornerstone for treatment of CCHF. Till date there is no FDA approved drug or definitive treatment for CCHF, ribavirin is tried by many physician need to be evaluated further. Current article is an effort to update existing knowledge about CCHF by due focus on various aspects especially prevention of this zoonotic disease. Much of the real life queries about this disease are elaborated after extensive literature research. [Int J Res Med Sci 2014; 2(2.000: 392-397

    A follicular wave and luteolysis were induced in mares by ablation of follicles > or =6 mm and treatment with prostaglandin F(2alpha) (PGF) on Day 10 (where ovulation = Day 0). The incidence of haemorrhagic anovulatory follicles (HAFs) in the induced waves (20%) was greater (P dynamics were compared between induced follicular waves that ended in ovulations (ovulating group; n = 36) v. HAFs (HAF group; n = 9). The day of the first ovulation or the beginning of HAF formation at the end of an induced wave was designated as post-treatment Day 0. The mean 13-day interval from Day 10 (PGF and ablation) to the post-treatment ovulation was normalised into Days 10 to 16, followed by Day -6 to Day 0 relative to the post-treatment ovulation. Concentrations of LH were greater (P < 0.05) in the HAF group than in the ovulating group on Days 10, 11, 12, 14, -3 and -2. The HAF group had greater (P < 0.003) LH concentrations on Day 10 of the preceding oestrous cycle with spontaneous ovulatory waves. The diameter of the largest follicle was less (P < 0.05) in the HAF group on most days between Day 13 and Day -1 and this was attributable to later (P < 0.002) emergence of the future largest follicle at 6 mm in the HAF group (Day 12.4 +/- 0.5) than in the ovulating group (Day 11.3 +/- 0.1). The results indicate that the high incidence of HAFs after PGF and ablation was associated with later follicle emergence and immediate and continuing greater LH concentration after PGF treatment, apparently augmented by an inherently high pretreatment LH concentration.

Due to upper airway obstruction, they are also vulnerable to sleep disorders. This study aims to assess the sleep variables, through polysomnography, and masticatory dynamics, using electromiography, before and after neuromuscular electrical stimulation, associated or not with low power laser (Gallium Arsenide- Aluminun, =780 nm and LED (= 660 nm irradiation in CP patients. Methods/design 50 patients with CP, both gender, aged between 19 and 60 years will be enrolled in this study. The inclusion criteria are: voluntary participation, patient with hemiparesis, quadriparesis or diparetic CP, with ability to understand and respond to verbal commands. The exclusion criteria are: patients undergoing/underwent orthodontic, functional maxillary orthopedic or botulinum toxin treatment. Polysomnographic and surface electromyographic exams on masseter, temporalis and suprahyoid will be carry out in all sample. Questionnaire assessing oral characteristics will be applied. The sample will be divided into 5 treatment groups: Group 1: neuromuscular electrical stimulation; Group 2: laser therapy; Group 3: LED therapy; Group 4: neuromuscular electrical stimulation and laser therapy and Group 5: neuromuscular electrical stimulation and LED therapy. All patients will be treated during 8 consecutive weeks. After treatment, polysomnographic and electromiographic exams will be collected again.

    Acute bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worsening confusion over a 3-week period. Brain CT scan findings were highly suggestive of a third ventricular colloid cyst with intraventricular rupture. He underwent cyst excision and histopathology, which confirmed the radiological diagnosis with evidence of haemorrhage within the cyst. A ventriculo peritoneal shunt was performed for delayed hydrocephalus. Surgical management of these patients must include emergency ventriculostomy followed by prompt surgical removal of the haemorrhagic cyst.

    2014-01-01

    Full Text Available Juxtafacet cysts are an uncommon cause of radiculopathy. They occur most frequently in the lumbar region, and their distribution across the spine correlates with mobility. Haemorrhagic complications are rare and may occur in the absence of any provocation, although there is some association with anticoagulation and trauma. We present a case of acute radiculopathy due to an L5/S1 juxtafacet cyst with unprovoked haemorrhage which was found to extend into ligamentum flavum. The patient underwent uncomplicated microscope assisted decompression with excellent results. The demographics, presentation, aetiology, and management of juxtafacet cysts are discussed.

    In this study the authors used a single photon emission computed tomography technique (SPECT) with radiolabelled [sup 99m]Tc HMPAO to assess cerebral perfusion in newborn infants with documented cerebral lesions and to determine to what extent brain SPECT might be useful in the neonatal period. A total of 15 newborn infants with the following cerebral pathologies were enrolled: severe parietal bilateral periventricular leucomalacia; moderate parietal bilateral PVL; intraventricular haemorrhage grade II with unilateral parietal parenchymal extension; cerebral infarction in the zone of middle cerebral artery; and post-haemorrhagic hydrocephalus. Follow-up was available in all infants. Alterations in cerebral perfusion were seen in only 12 of 15 infants and at the location of severe PVL, PE and CI. It was noted that the regions of diminished perfusion extended beyond the apparent extent of cerebral pathology delineated by ultrasound or magnetic resonance imaging. Markedly diminished perfusion was seen in one infant with hydrocephalus, which recovered following placement of ventriculo-peritoneal shunt. Regarding outcome, SPECT data failed to provide additional information than that of neuroradiological investigations. It is concluded that the use of SPECT, under these conditions, to assess alteration of cerebral perfusion in the neonatal period will not provide any additional information than that of neuroradiological investigations. 17 refs., 3 figs., 1 tab.

  11. Experience of the Irish National Centre for hereditary haemorrhagic telangiectasia 2003-2008.

    Hereditary haemorrhagic telangiectasia (HHT) is a group of autosomal dominant disorders of vascular structure. The Irish National Centre for HHT at the Mercy University Hospital, Cork, Ireland was founded in 2003. From 2003 to 2008, screening of 164 patients with contrast echocardiography, thoracic computerised tomography (CT) and cerebral magnetic resonance imaging (MRI) has identified 88 patients with definite HHT, 72 (82%) of whom had epistaxis, 70 (80%) had telangiectasia and 81 (92%) had a first-degree relative with HHT. We sought to describe the manifestations of HHT in an Irish population and to determine differences between internationally reported data. The HHT patient database was analysed to describe demographics, clinical manifestations and interventional procedures performed in all referred patients. Contrast echocardiography and\\/or CT were performed in 86 patients with definite HHT, identifying 27 patients (31%) with pulmonary arteriovenous malformations (pAVMs). Nineteen patients with single or multiple pAVMs had 28 embolisation procedures performed, with 1-6 pAVMs embolised per procedure. Cerebral MRI was performed in 78 (89%) patients and 2 (2.3%) had cerebral arteriovenous malformations (cAVMs). HHT prevalence is thought to be 1 in 2500-8000, suggesting that there are many undiagnosed cases in Irish patients. Internationally published data suggest a prevalence of 15-35% for pAVMs and 10-23% for cAVMs in patients with HHT. While the prevalence of pAVMs in our group is consistent with these data, the prevalence of cAVMs is considerably lower, suggesting that Irish patients with HHT may differ genotypically and phenotypically from those in other countries.

  12. Cerebral salt wasting syndrome: a case report.

    Science.gov (United States)

    Hegde, R M

    1999-06-01

    A case of hyponatraemia associated with subarachnoid haemorrhage is presented. The provisional diagnosis of an inappropriate antidiuresis was made and treatment with fluid restriction was instituted. However the patient continued to deteriorate as the diuresis continued and the hyponatraemia worsened, resulting in hypovolaema. The salt wasting syndrome was subsequently diagnosed and saline and fludrocortisone (0.2 mg/day) was initiated, reducing the renal salt loss, increasing the plasma sodium and improving the neurological status of the patient. Cerebral salt wasting syndrome is an important and under-recognised cause of hyponatraemia in neurosurgical patients, particularly in patients with subarachnoid hemorrhage. It is essential to differentiate it from the syndrome of inappropriate antidiuretic hormone secretion to avoid complications of hypovolaemia and reduced cerebral perfusion as illustrated by this case. Brain natriuretic peptide may be responsible for this syndrome although this requires further investigation.

    Cerebral palsy is the most common cause of childhood-onset, lifelong physical disability in most countries, affecting about 1 in 500 neonates with an estimated prevalence of 17 million people worldwide. Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy. Although the disorder affects individuals throughout their lifetime, most cerebral palsy research efforts and management strategies currently focus on the needs of children. Clinical management of children with cerebral palsy is directed towards maximizing function and participation in activities and minimizing the effects of the factors that can make the condition worse, such as epilepsy, feeding challenges, hip dislocation and scoliosis. These management strategies include enhancing neurological function during early development; managing medical co-morbidities, weakness and hypertonia; using rehabilitation technologies to enhance motor function; and preventing secondary musculoskeletal problems. Meeting the needs of people with cerebral palsy in resource-poor settings is particularly challenging. PMID:27188686

    Full Text Available Abstract Background Children with cerebral palsy (CP whom are non-ambulant are at risk of reduced quality of life and poor health status. Severe spasticity leads to discomfort and pain. Carer burden for families is significant. This study aims to determine whether intramuscular injections of botulinum toxin A (BoNT-A combined with a regime of standard therapy has a positive effect on care and comfort for children with CP whom are non-ambulant (GMFCS IV/V, compared with standard therapy alone (cycle I, and whether repeated injections with the same regime of adjunctive therapy results in greater benefits compared with a single injecting episode (cycle II. The regime of therapy will include serial casting, splinting and/or provision of orthoses, as indicated, combined with four sessions of goal directed occupational therapy or physiotherapy. Method/design This study is a double blind randomized controlled trial. Forty participants will be recruited. In cycle I, participants will be randomized to either a treatment group who will receive BoNT-A injections into selected upper and/or lower limb muscles, or a control group who will undergo sham injections. Both groups will receive occupational therapy and /or physiotherapy following injections. Groups will be assessed at baseline then compared at 4 and 16 weeks following injections or sham control. Parents, treating clinicians and assessors will be masked to group allocation. In cycle II, all participants will undergo intramuscular BoNT-A injections to selected upper and/or lower limb muscles, followed by therapy. The primary outcome measure will be change in parent ratings in identified areas of concern for their child’s care and comfort, using the Canadian Occupational Performance Measure (COPM.

  19. Transcatheter arterial embolization massive of haemorrhage in pelvic fracture

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical therapeutic effect of transcatheter arterial embolization (TAE) for treating massive haemorrhage in pelvic fracture (traffic accident 23, fall injury 5, hit trauma 4, crush injury 3). Methods: Thirty five patients with massive haemorrhage of pelvic fracture(traffic accident 23, fall injury 5, hit trauma 4, crush injury 3), also included 18 complicated injury cases. The inguinal region with free of or small hematoma was apt for femoral arterial puncture and followed by transcatheter bilateral iliac arterioangiography in order to confirm the site of haemorrhage. The gelfoam embolization was performed with superselective catheterization, otherwise the trunk of iliac artery would be embolized to slow down the blood flow and then coils with diameter from 5 to 8 mm were used for embolizing the trunk of iliac artery finally. The bilateral iliac arteries were embolized in the case of patients with bilateral or intermediate fracture. Results: Arterial spasm occurred in all patients with different severities and the patchy or linear extravasation of the contrast agent appeared in 29 patients through arteriography. All patients passed a successful embolization with a recovery of normal blood pressure (90-130)/(60-90)mmHg within 24 hours, without serious complications except one person had a minor skin necrosis at the distal part of big toe. Conclusions: The transcatheter arterial embolization is a simple, minimally invasive, safe and effective procedure, for treating the massive haemorrhage of pelvic fracture. (authors)

    The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.

    To examine the incidence of haemorrhage following tonsillectomy, to explore the usefulness of antibiotic in preventing postoperative haemorrhage and to examine if the haemorrhage depended on the level of expertise of the surgeon. A retrospective review analysing tonsillectomy method, the rate secondary haemorrhage, the grade of operating surgeon. A χ(2) analysis was used to determine the statistical difference between the haemorrhage rates of different tonsillectomy methods. One thousand three hundred and thirty-six tonsillectomies were performed during this period by four different methods: 615 by cold steel dissection, 582 by Coblation, 32 by bipolar dissection and 107 by Helica thermal coagulation. 621 tonsillectomies were performed by Consultant grade and middle grades performed 693 operations. 124 patients (9.3 %) were readmitted with haemorrhage. The secondary haemorrhage requiring surgery for controlling bleeding for cold steel dissection method was 1.5 % compared to 6.7 % for coblation method (P tonsillectomy haemorrhage rate of 5.5 % and middle grades had a rate of 3.7 %. 86.5 % of the patients were already on routine prophylactic oral antibiotics at the time of presentation with haemorrhage needing surgical arrest and 13.5 % were not on antibiotics (P coblation and cold steel dissection methods. Coblation tonsillectomies had an increased need for operative intervention to control secondary haemorrhage. Routine use of antibiotic and expertise of operating surgeon had no bearing on secondary haemorrhage rate.

    Spreading depolarization of cells in cerebral grey matter is characterized by massive ion translocation, neuronal swelling and large changes in direct current-coupled voltage recording. The near-complete sustained depolarization above the inactivation threshold for action potential generating channels initiates spreading depression of brain activity. In contrast, epileptic seizures show modest ion translocation and sustained depolarization below the inactivation threshold for action potential generating channels. Such modest sustained depolarization allows synchronous, highly frequent neuronal firing; ictal epileptic field potentials being its electrocorticographic and epileptic seizure its clinical correlate. Nevertheless, Leão in 1944 and Van Harreveld and Stamm in 1953 described in animals that silencing of brain activity induced by spreading depolarization changed during minimal electrical stimulations. Eventually, epileptic field potentials were recorded during the period that had originally seen spreading depression of activity. Such spreading convulsions are characterized by epileptic field potentials on the final shoulder of the large slow potential change of spreading depolarization. We here report on such spreading convulsions in monopolar subdural recordings in 2 of 25 consecutive aneurismal subarachnoid haemorrhage patients in vivo and neocortical slices from 12 patients with intractable temporal lobe epilepsy in vitro. The in vitro results suggest that γ-aminobutyric acid-mediated inhibition protects from spreading convulsions. Moreover, we describe arterial pulse artefacts mimicking epileptic field potentials in three patients with subarachnoid haemorrhage that ride on the slow potential peak. Twenty-one of the 25 subarachnoid haemorrhage patients (84%) had 656 spreading depolarizations in contrast to only three patients (12%) with 55 ictal epileptic events isolated from spreading depolarizations.

    2016-01-01

    [Purpose] Evaluating the effect of brain-computer interface (BCI)-based functional electrical stimulation (FES) training on brain activity in children with spastic cerebral palsy (CP) was the aim of this study. [Subjects and Methods] Subjects were randomized into a BCI-FES group (n=9) and a functional electrical stimulation (FES) control group (n=9). Subjects in the BCI-FES group received wrist and hand extension training with FES for 30 minutes per day, 5 times per week for 6 weeks under the BCI-based program. The FES group received wrist and hand extension training with FES for the same amount of time. Sensorimotor rhythms (SMR) and middle beta waves (M-beta) were measured in frontopolar regions 1 and 2 (Fp1, Fp2) to determine the effects of BCI-FES training. [Results] Significant improvements in the SMR and M-beta of Fp1 and Fp2 were seen in the BCI-FES group. In contrast, significant improvement was only seen in the SMR and M-beta of Fp2 in the control group. [Conclusion] The results of the present study suggest that BCI-controlled FES training may be helpful in improving brain activity in patients with cerebral palsy and may be applied as effectively as traditional FES training.

    BACKGROUND: Several studies have demonstrated that sustained cognitive tasks can induce cognitive fatigue and that the mean cerebral blood flow velocity changes in some cerebral regions during cerebral fatigue. OBJECTIVE: To dynamically monitor the changes in mean cerebral blood flow velocity in different brain regions of high performance fighter pilots during mental arithmetic tasks and consecutive performance tasks. DESIGN, TIME AND SETTING: The present neurophysiological trial, based on controlled observation, was performed at the Laboratory of Neurophysiology, Institute of Aviation Medicine, Air Force of China between January 2003 and December 2005. PARTICIPANTS: Forty-five males, high performance fighter pilots, averaging (27.6 ± 2.5) years, were recruited for this study. METHODS: The mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery of subjects was dynamically tested using transcranial Doppler during 5- hour mental arithmetic tasks and during 5- hour consecutive performance tasks. The neurobehavioral ability index was analyzed throughout each trial according to the number of correct responses, false responses, and lost responses. Simultaneously, cerebral cognitive fatigue-induced lethargy was assessed by the Stanford Sleepiness Scale. MAIN OUTCOME MEASURES: Changes in mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery; neurobehavioral ability index of mental arithmetic and consecutive performance tasks; Stanford Sleepiness Scale scores. RESULTS: During mental arithmetic tasks, the mean cerebral blood flow velocity in the anterior cerebral artery increased during hour 2 and decreased after hour 4. There was no significant change in mean cerebral blood flow velocity in the middle cerebral artery and posterior cerebral artery. During hour 4, cerebral cognitive fatigue was observed and, simultaneously, Stanford Sleepiness

    Full Text Available Abstract Background Persons with cerebral palsy (CP are at risk for developing an inactive lifestyle and often have poor fitness levels, which may lead to secondary health complications and diminished participation and quality of life. However, persons with CP also tend not to receive structural treatment to improve physical activity and fitness in adolescence, which is precisely the period when adult physical activity patterns are established. Methods We aim to include 60 adolescents and young adults (16-24 years with spastic CP. Participants will be randomly assigned to an intervention group or a control group (no treatment; current policy. The intervention will last 6 months and consist of three parts; 1 counselling on daily physical activity; 2 physical fitness training; and 3 sports advice. To evaluate the effectiveness of the intervention, all participants will be measured before, during, directly after, and at 6 months following the intervention period. Primary outcome measures will be: 1 physical activity level, which will be measured objectively with an accelerometry-based activity monitor during 72 h and subjectively with the Physical Activity Scale for Individuals with Physical Disabilities; 2 aerobic fitness, which will be measured with a maximal ramp test on a bicycle or armcrank ergometer and a 6-minute walking or wheelchair test; 3 neuromuscular fitness, which will be measured with handheld dynamometry; and 4 body composition, which will be determined by measuring body mass, height, waist circumference, fat mass and lipid profile. Conclusions This paper outlines the design, methodology and intervention of a multicenter randomized controlled trial (LEARN 2 MOVE 16-24 aimed at examining the effectiveness of an intervention that is intended to permanently increase physical activity levels and improve fitness levels of adolescents and young adults with CP by achieving a behavioral change toward a more active lifestyle.

    Coblation is a new soft tissue surgical technique that is being used for tonsillectomy. Published results show a significant decrease in the amount of post-operative pain experienced by patients undergoing coblation tonsillectomy. There has been no published work to date on the incidence of post-operative haemorrhage. From August 2001 to November 2002 one surgeon performed 36 coblation tonsillectomies on adults. On another list he performed 29 by his standard method of dissection and bipolar coagulation. Retrospective analysis found a significant increase in the secondary haemorrhage rate in adult patients undergoing coblation tonsillectomy (22.2 vs. 3.4 per cent). At our department coblation tonsillectomy has been abandoned until further work into its safety has been published.

  18. Detection and localization of internal haemorrhaging using electrical bioimpedance

    International Nuclear Information System (INIS)

    Electrical bioimpedance is an effective measuring tool to provide quick, non-invasive, real-time results which will be applied to the detection of internal haemorrhaging. Experiments were performed on female Fancy Rats weighing 333±44g, and 10mL of porcine blood was injected abdominally over 3 minutes. Data was collected using an 8×8 needle electrode array at 5 kHz, and 95 kHz and sent to the BioParHom Z-Flow. A strong correlation was found between the electrode paths crossing directly through the blood injection site, showing a decrease of about −0.17±0.1Ω/mL for the 5 kHz frequency. This correlation allows us to quickly detect internal haemorrhaging and also localize it with the current path set-up in the electrode array.

  6. Post eclamptic aneurysmal rupture subarachnoid haemorrhage diagnosed in the puerperium

    International Nuclear Information System (INIS)

    The incidence of subarachnoid and/or intracerebral haemorrhage in women during pregnancy is rare. The risk depends on the stage of pregnancy, but seems to be highest during the late third trimester, during delivery and in the puerperium. Headache can be a symptom of both preeclampsia, subarachnoid haemorrhage and other pathologies or conditions. It is essential for pregnant women with a suspected ruptured aneurysm to be investigated and treated without delay, irrespective of fear of harm to the foetus, to avoid complications from aneurysm rupture. This case study presents a 39-year-old woman who was 35 weeks and 3 days pregnant with known preeclampsia. She endured a headache for the three days leading up to the delivery with associated diplopia on the third day, but these symptoms were thought to be related to her preeclampsia. Over the three hours following childbirth, her headache became more severe and she suffered from vomiting, loss of vision, torticollis and seizures. Computed tomography (CT) of her head revealed a subarachnoid haemorrhage while CT angiography of the Circle of Willis failed to reveal an aneurysm and 4-vessel angiography only demonstrated an area slightly suspicious for the presence of an aneurysm. 3D rotational angiography clearly demonstrated a 1-2 mm aneurysm superior to the left terminal internal carotid artery. In this case, 3D rotational angiography proved to be a valuable additional technique. This patient underwent surgery for her ruptured aneurysm and has made an excellent recovery

    Full Text Available Context Autoimmune pancreatitis is a rare but increasingly reco gnised condition with unique clinical, immunologica l and histological features. We report the first case of auto immune pancreatitis associated with spontaneous sple nic haemorrhage. Case report A 75-year-old man presented with severe epigastric pa in radiating to the back associated with nausea and vomiting. A CT-scan of his abdomen showed a large ps eudocyst within the pancreatic tail as well as a sub capsular splenic haemorrhage. His IgG4 levels were elevated and clinica l history and investigations were consistent with se vere acute pancreatitis, but were negative for other known causes of pancreatic disease. The patient was started on ste roid therapy and improved dramatically clinically, immunologically and radiologically thus confirming the diagnosis of auto immune pancreatitis. His splenic haemorrhage was managed cons ervatively in view of his haemodynamic stablity and eventually self- resolved. Conclusion Autoimmune pancreatitis should not be overlooked in cases of acute pancreatitis without other obvious etiology. Furthermore, superimposed splenic hae morrhage is a rare but important complication of autoimm une pancreatitis.

    5α-reductase inhibitors (5α-RIs), including finasteride and dutasteride, are commonly used medical therapies for benign prostatic hyperplasia (BPH). Many studies reported that preoperative 5α-RI had impact on intraoperative haemorrhage during surgery for BPH, but it was still in controversial. So, we conducted a systematic review of the effects and mechanisms of 5α-RIs on intraoperative bleeding for BPH. MEDLINE, EMBASE, the Cochrane Controlled Trail Register of Controlled Trials and the reference lists of retrieved studies were searched in the analysis. Sixteen publications involving 15 different randomized controlled trials (RCTs) and a total of 1156 patients were used in the analysis, including 10 RCTs for finasteride and five RCTs for dutasteride. We found that preoperative finasteride treatment decreases microvessel density (MVD) in resected prostate specimens. Total blood loss, blood loss per gram of resected prostate tissue and decreases in haemoglobin were all greatly reduced in the finasteride group as compared to controls. Dutasteride appeared to have no effect on bleeding. This meta-analysis shows that preoperative finasteride treatment could decrease intraoperative haemorrhage during surgery for BPH. Preoperative dutasteride had no effect on intraoperative haemorrhage, but further high-quality prospective studies are still needed to confirm this observation. PMID:21892196

    Full Text Available Background: Postpartum haemorrhage (PPH is a leading cause of maternal mortality especially in the developing world. Misoprostol, a highly effective drug is highly effective in inducing uterine contractions and has been proposed as a low-cost, easy-to-use intervention for PPH.Objective: This study assessed evidence of the effectiveness of misoprostol for the prevention and treatment of PPH.Method: Databases searched included MEDLINE, PUBMED, CINHAL, Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL and EMBASE. Reference lists and conference proceedings were also searched for more studies. Three studies included in the meta-analysis were limited to randomised controlled trials (RCT. Two reviewers independently screened all articles for methodological quality using a standardised instrument adapted from the Cochrane Collaboration website. Data were entered in Review Manager 5.1 software for analysis.Results: Three trials (n = 2346 compared misoprostol to a placebo. Misoprostol was shown not to be effective in reducing PPH (risk ratios [RR] 0.65; 95% confidence interval [CI] 0.40–1.06. Only one trial reported on the need for a blood transfusion (RR 0.14; 95% CI 0.02–1.15. Shivering (RR 2.75; 95% CI 2.26–3.34 and pyrexia (RR 5.34; 95% CI 2.86–9.96 were significantly more common with misoprostol than with a placebo.Conclusion: The use of misoprostol was not associated with any significant reduction in the incidence of PPH. Therefore, in order to verify the efficacious use of misoprostol in the treatment of PPH, specialised investigations of its dose and routes of administration for clinically significant effects and acceptable side effects are warranted.

    Full Text Available Abstract Background Little is known about the efficacy and the working mechanisms of physical and occupational therapy interventions for children with cerebral palsy (CP. In recent years a shift from a child-focused intervention approach to a more context-focused intervention approach can be recognized. Until now the evidence on the efficacy and the working mechanisms of these interventions for children with CP is inconclusive. This study aims to evaluate the efficacy and working mechanisms of two intervention approaches compared to regular care intervention in improving mobility and self-care skills of children (2-3 years with CP and their families: a child-focused intervention approach and a context-focused intervention approach. Methods/Design A multi-centre, randomized controlled trial research design will be used. Ninety-four children with CP (Gross Motor Function Classification System (GMFCS level I-IV; age 2 to 3 years, their parents, and service providers (physical and occupational therapists will be included. During a period of six months children will receive child-focused, context-focused or regular care intervention. Therapists will be randomly assigned to deliver either a child-focused intervention approach, a context-focused intervention approach or regular care intervention. Children follow their therapist into the allocated intervention arm. After the six months study-intervention period, all participants return to regular care intervention. Outcomes will be evaluated at baseline, after six months and at a three months follow-up period.

En cuanto a las hemorragias del primer trimestre se ha hecho mayor hincapié en el manejo del aborto, puesto que otras entidades que también son frecuentes se valoran de manera específica en otros capítulos. En el segundo trimestre se ha realizado una revisión de tres entidades que abarcan el mayor porcentaje de hemorragias en ese periodo, como son la placenta previa, el desprendimiento prematuro de placenta normalmente inserta y la rotura uterina. Hemos valorado en cada una de ellas la etiopatogenia, la actitud diagnóstica y el manejo de la forma más sistemática posible.A haemorrhage is one of the most frequent, and potentially most serious, causes for emergency consultation during gestation. In this review we offer an overall approach to managing a pregnant woman who attends Accidents and Emergencies due to vaginal bleeding and then, in a more specific way, we consider how to manage some of the most frequent entities of the obstetric haemorrhage. With respect to haemorrhages in the second trimester, we give greater attention to how to manage a miscarriage, since other entities that are also frequent receive a specific evaluation in other chapters. In the second trimester three entities account for the greatest percentage of haemorrhages, such as placenta praevia, the premature detachment of the normally inserted placenta and uterine rupture. In each case we have evaluated the etiopathology, diagnostic attitude and management in the most systematic way possible.

  1. Management of symptomatic thrombocytopenia associated with dengue haemorrhagic fever

    International Nuclear Information System (INIS)

    Introduction: Immune - mediated destruction of platelets is thought to be the mechanism of thrombocytopenia seen after the viraemic phase of dengue haemorrhagic fever (DHF). Immuno - suppressants such as steroids, immune globulin and Anti D immune globulin are effective in the treatment of this type of immune thrombocytopenic purpura. Objective: To evaluate the efficacy of oral Prednisolone in the rate of resolution of thrombocytopenia and monitoring of complications in patients recovering from Dengue haemorrhagic fever. Method: A controlled study was carried out on diagnosed cases Dengue haemorrhagic patients presenting with sever thrombocytopenia and symptoms like confluent ecchymosis, epistaxis and purpuric rashes. In study was conducted in Ittefaq hospital (trust) Lahore, during the period of October to December 2008. Treatment group received steroids in two forms i.e. first line therapy prednisolone (1 mg / kg) orally or as second line therapy of initial I/V high dose (prednisolone) in pulse doses i.e. 40 mg / bd for four days and later oral prednisolone as in first line therapy with omeprazole 20 mg / bd in addition to standard treatment. Control group received standard supportive care only. Results: A total of 341 suspected patients were admitted in hospital. Serological diagnosis was confirmed in 166 patients. CBC revealed platelet count . 100 x 109 / l in 106 patients. A group of symptomatic febrile patients have platelet count < 20 x 109 / l was selected for therapeutic intervention. first line therapy (oral prednisolone was stated in 43 patients. In Fourteen patients second line therapy (high dose dexamethasone pulse) therapy was instituted. Seven of them attained complete response whereas two patients achieved partial response. Four patients were shifted to Anti D therapy. Three deaths occurred during our study. Rest of all the patients improved and were discharged in due course of time. Conclusion: This small scale preliminary study shows promising

    Presentation of pericardial disease is diverse, with the viral aetiology being the most common cause; however, when haemorrhagic pericardial effusion is present, these causes are narrowed to few aetiologies. We present a case of a young female of African descent who presented with diffuse abdominal pain and vomiting. Initial work-up showed pericardial effusion with impending echocardiographic findings of cardiac tamponade and bilateral pleural effusions. Procedures included a left video-assisted thoracoscopic surgery (VATS) with pericardial window. We consider that it is important for all physicians to be aware of not only typical presentation but also atypical and unusual clinical picture of pericardial disease.

In roughly 15 % of the cases, the cause is due to an intracranial haemorrhage, and the remaining 85 % represent ischemic strokes. Ischemic stroke is caused by the occlusion of a cerebral artery...... either by an embolus or by local thrombosis. Several studies have shown an involvement of the endothelin system in ischemic stroke. This review aims to examine the alterations of vascular endothelin receptor expression in ischemic stroke. Furthermore, studies of the intracellular signalling pathways...... leading to the enhanced expression of vascular endothelin receptors show that both protein kinase C (PKC) and mitogen activating protein kinase (MAPK) play important roles. The results from this work provide new perspectives on the pathophysiology of ischemic stroke, and give a possible explanation...

    Background A delayed post-pancreatoduodenectomy haemorrhage is associated with a significant increase in peri-operative mortality. Endovascular techniques are frequently used for a delayed haemorrhage. However, limited data exists on the short- and long-term outcomes of this approach. A retrospective review over a 10-year period at a quaternary-referral pancreatic centre was performed. Methods Between 2002–2012, 1430 pancreatoduodenectomies were performed, and 32 patients had a delayed haemorrhage (occurring >24 h post-operatively) managed by endovascular techniques. The clinicopathological variables related to a haemorrhage were investigated. Results A total of 42 endovascular procedures were performed at a median of 25 days, with the majority of delayed haemorrhages occurring after 7 days. There were four deaths (13%) with three occurring in patients with a grade C haemorrhage. Seven patients (22%) experienced rebleeding, and two patients developed hepatic abscesses. Conclusion A delayed haemorrhage post-pancreaticoduodenectomy can be managed by endovascular techniques with acceptable morbidity and mortality. Rebleeding and hepatic abscesses may occur and can be managed non-operatively in most cases. The association of a delayed haemorrhage with a pancreatic fistula makes this a challenging clinical problem. PMID:26235930

    The purpose of this paper is to investigate the clinical significance of postinterventional subarachnoid hyperdensities (PSH) after endovascular mechanical thrombectomy in acute ischemic stroke. We analysed clinical and radiological data of 113 consecutive patients who received postinterventional CT scans within 4.5 h after mechanical thrombectomy. PSH was present in 27 of 113 patients (24 %). Extravasation of contrast agent was observed during intervention in only 6 of 27 cases (22 %). There was consecutive haemorrhagic transformation in four patients with PSH (p = 0.209, Fisher's exact test). Preinterventional predictors for the occurrence of PSH in our series were a long interval between clinical onset and recanalization (p = 0.028), a long procedure time (p = 0.010), and a high number of recanalization attempts (p = 0.001). PSH had no significant impact on clinical outcome (modified Rankin Scale) at discharge (p = 0.419) or at 3 months (p = 0.396). There were no significant correlations between PSH and thrombectomy devices (Solitaire: p = 0.433, Trevo Pro: p = 0.124). PSH after endovascular mechanical thrombectomy in acute ischemic stroke are likely to occur in complicated cases in which more than one revascularisation attempt is performed. PSH per se do not appear to be associated with an impaired clinical outcome or an elevated risk for consecutive haemorrhage. (orig.)

    Haemorrhagic septicaemia caused by Pasteurella multocida is a major epizootic disease in cattle and buffaloes in developing countries with high morbidity and mortality rate. In the present study, a total of 88 P. multocida isolates were isolated from 256 nasopharyngeal swabs and lung tissues samples (34.4%) during the period from January, 2013 to March, 2014 from different governorates located in Egypt. Dead calves showed the highest percentage of P. multocida isolation followed by the emergency slaughtered calves, diseased calves then apparently healthy ones. These isolates were confirmed as P. multocida microscopically, biochemically by traditional tests and by API 20E commercial kit then by PCR. The percentages of positive serum samples using somatic antigen and micro-agglutination test at 1/1280 diluted serum were 10%, 54.49% and 0% in apparently healthy, diseased and emergency slaughtered samples, respectively whereas, the percentages using capsular antigen and indirect haemagglutination test were 40%, 60.89% and 60% in apparently healthy, diseased and emergency slaughtered samples, respectively. The ELISA showed the highest sensitivity for diagnosing P. multocida in apparently healthy, diseased and emergency slaughtered animals with percentages of 42%; 92.9% and 80%, respectively. The obtained results revealed that the ELISA using capsular antigen of P. multocida is a more sensitive and specific serological test for diagnosis of haemorrhagic septicaemia. PMID:26858538

    BACKGROUND: Implant infection and obstruction are major complications for ventriculoperitoneal shunts in patients with post-haemorrhagic hydrocephalus. In an effort to (1) reduce the incidence of these complications, (2) reduce the rate of shunt failure and (3) shorten the duration of neurosurgical...... hospitalisation, we have implemented valveless ventriculoperitoneal shunts at our department for adult patients with post-haemorrhagic hydrocephalus and haemorrhagic cerebrospinal fluid at the time of shunt insertion. METHODS: All adult patients (>18 years old) treated for post-haemorrhagic hydrocephalus.......3 %, p = 0.02), but a higher rate of overdrainage (10.3 % vs 2.6 %, p = 0.04). CONCLUSION: The use of a valveless shunting for patients with post-haemorrhagic hydrocephalus results in shorter duration of neurosurgical hospitalisation and lower rate of shunt infection, although these advantages should...

    A haemorrhagic toxin (VRR-12) from Vipera russelli russelli (Russell's viper) venom has been purified by ion-exchange chromatography on CM-Sephadex C-50 followed by size-exclusion HPLC to electrophoretically homogeneous state. It is a 12 kDa single polypeptide having 1 mole of Zn+2 ion. This toxin induces intense intestinal haemorrhage and to a lesser extent skeletal muscle haemorrhage in mice. It does not show detectable proteolytic and esterolytic activity with selected substrates under specified conditions, haemolytic and phospholipase activity. When VRR-12, preincubated with bivalent antiserum against Saw-scaled and Russell's viper venom or EDTA was injected, haemorrhagic activity was not reduced, on the other hand preincubation with phenylmethyl sulphonyl fluoride reduced the activity markedly. Biodistribution studies with 125I VRR-12 show that haemorrhagic manifestation by this toxin is not a direct function of the fraction of the totally administered toxin distributed to that tissue.

    2013-01-01

    Malaria, the most significant parasitic disease of man, kills approximately one million people per year. Half of these deaths occur in those with cerebral malaria (CM). The World Health Organization (WHO) defines CM as an otherwise unexplained coma in a patient with malarial parasitemia. Worldwide, CM occurs primarily in African children and Asian adults, with the vast majority (greater than 90%) of cases occurring in children 5 years old or younger in sub-Saharan Africa. The pathophysiology of the disease is complex and involves infected erythrocyte sequestration, cerebral inflammation, and breakdown of the blood-brain barrier. A recently characterized malarial retinopathy is visual evidence of Plasmodium falciparum's pathophysiological processes occurring in the affected patient. Treatment consists of supportive care and antimalarial administration. Thus far, adjuvant therapies have not been shown to improve mortality rates or neurological outcomes in children with CM. For those who survive CM, residual neurological abnormalities are common. Epilepsy, cognitive impairment, behavioral disorders, and gross neurological deficits which include motor, sensory, and language impairments are frequent sequelae. Primary prevention strategies, including bed nets, vaccine development, and chemoprophylaxis, are in varied states of development and implementation. Continuing efforts to find successful primary prevention options and strategies to decrease neurological sequelae are needed. PMID:23829902

    Haemorrhagic disorders like Postpartum haemorrhage and Dengue haemorrhagic fever are life threatening and requires an active and efficient transfusion service that could provide the most appropriate blood product which could be effective in managing them. This would essentially require prompt identification of the coagulopathy so that the best available product can be given to the bleeding patient to correct the identified haemostatic defect which will help control the bleeding. This would only be possible if the transfusion service has a laboratory to correctly detect the haemostatic defect and that too with an accuracy and precision which is ensured by a good laboratory quality assurance practices. These same processes are necessary for the transfusion services to ensure the quality of the blood products manufactured by them and that it contains adequate amounts of haemostasis factors which will be good to be effective in the management of haemorrhagic disorders. These issues are discussed in detail individually in the management of postpartum haemorrhage and Dengue haemorrhagic fever including when these can help in the use of rFVIIa in Dengue haemorrhagic fever. The requirements to ensure good-quality blood products are made available for the management of these disorders and the same have also been described. PMID:27405683

  15. Cerebral cysticercosis

    International Nuclear Information System (INIS)

    Two cases of histologically proven cerebral cysticercosis are presented. In both cases subcutaneous tissue nodules, a rare feature, were present. Several disease patterns are apparent - meningeal, parenchymatous and ventricular, spinal cord lesions and mixed patterns. Epilepsy is by far the major presenting symptom of cysticercosis, which in turn plays a significant role in the causation of adult-onset epilepsy in Blacks. Despite its drawbacks, the haemag-glutination inhibition test remains the most satisfactory serological method at present available for the diagnosis of cysticercosis; it is positive in up to 85% of cases of proven cysticercosis. With the advent of computed tomography many cases of unsuspected cysticercosis (symptomatic or asymptomatic) are being discovered

    Conclusions: Educating pregnant mothers about the importance of antenatal care and easy accessibility to quality antenatal services would go a long way in bringing down the maternal and perinatal morbidity and mortality related with antepartum haemorrhage. The morbidity associated with placenta previa can be reduced by detecting the condition in the antenatal period by ultrasound, before it becomes symptomatic. Intensive family planning program and awareness of small family norm helps in decreasing cases of APH in relation with age and parity. Efforts should be made to reduce the rates of operative deliveries, because there is a greater likelihood of placenta previa in a scarred uterus. There is a lot of scope on further research in the field of APH for further reduction in foetal and maternal morbidity and mortality. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 1936-1939

  17. Embolization for major lower gastrointestinal haemorrhage: five-year experience

    International Nuclear Information System (INIS)

    The management of major lower gastrointestinal haemorrhage has changed dramatically in the last 15 years. Innovations in coaxial catheter technology have allowed the interventional radiologist to reach the small peripheral mesenteric arteries and perform superselective embolization with a variety of agents. The present large series represents the 5-year experience of this technique at the Alfred Hospital, Melbourne, in a patient cohort with a high number of comorbidities. Technical success was achieved in 96% of cases. The clinical symptoms of mesenteric ischaemia developed in four patients after embolization and were managed conservatively in two. The procedure-related mortality was low when compared with the published complication rates for emergency surgery, in this clinical setting. Copyright (2004) Blackwell Publishing Asia Pty Ltd

    The aim of this study is to examine the incidence of return to theatre (RTT) for post-operative haemorrhage following coblation and dissection tonsillectomy and to investigate those that required RTT more than 10 days post-surgery. Retrospective review of post-tonsillectomy haemorrhages requiring RTT from April 2005 to March 2009 was conducted. Of 2,541 tonsillectomies performed, 81% were by coblation and 19% by dissection methods. The overall RTT rate was 1.7%. No difference was found in the overall RTT rates for primary and secondary haemorrhage between the two techniques. However, the overall RTT rates for primary and secondary haemorrhage were higher in adults than children (P = 0.0456 and P = 0.0215, respectively). RTT for secondary haemorrhage during the first ten post-operative days occurred in both coblation and dissection tonsillectomy with no significant difference. After the first post-operative week, late secondary bleeding requiring RTT occurred only in the coblation group (P = 0.0676). Four patients required blood transfusion; all were in the coblation group, three of which were required during RTT in the late secondary haemorrhage (after 10 days). The post-operative RTT rates for coblation tonsillectomy did not reveal a change of trend over the 4-year study period. Our RTT rate for secondary haemorrhage is higher than earlier published results. A learning curve could not be identified in RTT for coblation tonsillectomy haemorrhage. Late secondary haemorrhages requiring surgical intervention have only been identified in cases performed by coblation and could potentially be life threatening as 33% (3/9) required blood transfusion. This phenomenon may be explained by a particular physiological healing process associated with coblation.

    The present pair-matched case control study was carried out at Government Medical College Hospital, Nagpur, India, a tertiary care hospital with the objective to devise and validate a risk scoring system for prediction of hemorrhagic stroke. The study consisted of 166 hospitalized CT scan proved cases of hemorrhagic stroke (ICD 9, 431-432), and a age and sex matched control per case. The controls were selected from patients who attended the study hospital for conditions other than stroke. On conditional multiple logistic regression five risk factors- hypertension (OR = 1.9. 95% Cl = 1.5-2.5). raised scrum total cholesterol (OR = 2.3, 95% Cl = 1.1-4.9). use of anticoagulants and antiplatelet agents (OR = 3.4, 95% Cl =1.1-10.4). past history of transient ischaemic attack (OR = 8.4, 95% Cl = 2.1- 33.6) and alcohol intake (OR = 2.1, 95% Cl = 1.3-3.6) were significant. These factors were ascribed statistical weights (based on regression coefficients) of 6, 8, 12, 21 and 8 respectively. The nonsignificant factors (diabetes mellitus, physical inactivity, obesity, smoking, type A personality, history of claudication, family history of stroke, history of cardiac diseases and oral contraceptive use in females) were not included in the development of scoring system. ROC curve suggested a total score of 21 to be the best cut-off for predicting haemorrhag stroke. At this cut-off the sensitivity, specificity, positive predictivity and Cohen's kappa were 0.74, 0.74, 0.74 and 0.48 respectively. The overall predictive accuracy of this additive risk scoring system (area under ROC curve by Wilcoxon statistic) was 0.79 (95% Cl = 0.73-0.84). Thus to conclude, if substantiated by further validation, this scorincy system can be used to predict haemorrhagic stroke, thereby helping to devise effective risk factor intervention strategy.

  20. Helical CT in the diagnosis of acute lower gastrointestinal haemorrhage

    International Nuclear Information System (INIS)

    Introduction: A pilot study to evaluate helical computer tomography (CT) as a diagnostic tool for acute lower gastrointestinal tract (GIT) bleeding. CT was compared to conventional angiography (CA) and colonoscopy for the diagnosis and detection of bleeding site in suspected cases of acute lower GIT bleeding. Methods: Seven patients presenting with acute lower GIT bleeding, between June and November 2002, underwent CT examinations. All of these seven patients underwent CA following CT. Emergency colonoscopies were performed on five patients investigated with both CT and CA. Median delay from the most recent episode of hematochezia to CT was two and a half hours, to CA was 3 h, and to colonoscopy was 4 h. None of the patients underwent nuclear medicine (NM) bleeding studies. Results: Haemoglobin drop in all patients was greater than 15 g/L in the first 24 h of presentation. The mean age was 68.86 years (range, 49-83 years). Comparing CT and CA, there were four concordant and three discordant results. Both modalities had concordant findings of two active bleeding sites, one non-bleeding rectal tumour, and one negative case result. In three patients, the source of bleeding was found on CT whereas CA was negative. Emergency colonoscopies performed in all of these three patients confirmed blood in the colon/ileum. Conclusion: Early experience suggests that CT is a safe, convenient and accurate diagnostic tool for acute lower GIT haemorrhage. It raises questions regarding the sensitivity of CA. A new management algorithm for acute lower GIT haemorrhage using CT as the pre-CA screening tool is being proposed based on the preliminary findings. Positive CT will allow directed therapeutic angiography, while negative CT will triage patients into alternative management pathways

    Conventional digital subtraction angiography (DSA) is currently regarded as the gold standard in detecting underlying vascular pathologies in patients with intracerebral haemorrhages (ICH). However, the use of magnetic resonance imaging (MRI) in the diagnostic workup of ICHs has considerably increased in recent years. Our aim was to evaluate the diagnostic accuracy and yield of MRI for the detection of the underlying aetiology in ICH patients. Sixty-seven consecutive patients with an acute ICH who underwent MRI (including magnetic resonance angiography (MRA) and DSA during their diagnostic workup) were included in the study. Magnetic resonance images were retrospectively analysed by two independent neuroradiologists to determine the localisation and cause of the ICH. DSA was used as a reference standard. In seven patients (10.4%), a DSA-positive vascular aetiology was present (one aneurysm, four arteriovenous malformations, one dural arteriovenous fistula and one vasculitis). All of these cases were correctly diagnosed by both readers on MRI. In addition, MRI revealed the following probable bleeding causes in 39 of the 60 DSA-negative patients: cerebral amyloid angiopathy (17), cavernoma (9), arterial hypertension (8), haemorrhagic transformation of an ischaemic infarction (3) and malignant brain tumour with secondary ICH (2). Performing MRI with MRA proved to be an accurate diagnostic tool in detecting vascular malformations in patients with ICH. In addition, MRI provided valuable information regarding DSA-negative ICH causes, and thus had a high diagnostic yield in ICH patients. (orig.)

    In this study, we aimed to evaluate the incidence, risk factors, causes and clinical management of intracranial haemorrhage (ICH) diagnosed during foetal life or in the first month of life in term neonates with a discussion of the role of haematological risk factors. This study included term neonates (gestational age 37-42 weeks) with ICH diagnosed, treated and followed up in the Neonatal Intensive Care Unit of Hacettepe University, Ankara, Turkey, between January 1994 and January 2014. Medical follow-up was obtained retrospectively from hospital files and prospectively from telephonic interviews and/or clinical visits. During the study period, 16 term neonates were identified as having ICH in our hospital. In six (37.5%) neonates, ICH was diagnosed during foetal life by obstetric ultrasonography, and in 10 (62.5%) neonates, it has been diagnosed after birth. Haemorrhage types included intraventricular haemorrhage (IVH) in eight (50.0%), intraparenchymal haemorrhage in six (37.5%), subarachnoid haemorrhage in one (6.2%) and subdural haemorrhage in one (6.2%) neonate. IVH was the most common (n = 5/6, 83.3%) haemorrhage type among neonates diagnosed during foetal life. Overall, haemorrhage severity was determined as mild in three (18.7%) neonates, moderate in three (18.75%) neonates and severe in 10 (62.5%) neonates. During follow-up, one infant was diagnosed as afibrinogenemia, one diagnosed as infantile spasm, one cystic fibrosis, one orofaciodigital syndrome and the other diagnosed as Friedrich ataxia. Detailed haematological investigation and search for other underlying diseases are very important to identify the reason of ICH in term neonates. Furthermore, early diagnosis, close monitoring and prompt surgical interventions are significant factors to reduce disabilities. PMID:26829281

We present three patients who developed symptomatic spinal arachnoiditis following spontaneous aneurysm rupture. Following initial aneurysm and subarachnoid haemorrhage management (including ventriculo-peritoneal shunt placement), all three patients developed gradually worsening neurological abnormalities, and subsequent imaging demonstrated spinal arachnoiditis. Despite spinal decompression, all three patients experienced progressively worsening neurological decline.

    Full Text Available Toll-like receptor (TLR signalling begins early in subarachnoid haemorrhage (SAH, and plays a key role in inflammation following cerebral aneurysm rupture. Available studies suggest significance of endogenous first-line blockers of a TLR pathway-soluble TLR2 and 4.Eighteen patients with SAH and acute hydrocephalus underwent endovascular coiling and ventriculostomy; sTLR2 and 4 levels were assayed in cerebrospinal fluid (CSF collected on post-SAH days 0-3, 5, and 10-12. Release kinetics were defined. CSF levels of sTLR2 and 4 were compared with a control group and correlated with the clinical status on admission, the findings on imaging, the degree of systemic inflammation and the outcome following treatment.None of study group showed detectable levels of sTLR2 and 4 on post-SAH day 0-3. 13 patients showed increased levels in subsequent samples. In five SAH patients sTLR2 and 4 levels remained undetectable; no distinctive features of this group were found. On post-SAH day 5 the strongest correlation was found between sTLR2 level and haemoglobin level on admission (cc = -0.498, P = 0.037. On post-SAH day 10-12 the strongest correlation was revealed between sTLR2 and treatment outcome (cc = -0.501, P = 0.076. Remaining correlations with treatment outcome, status at admission, imaging findings and inflammatory markers on post-SAH day 5 and 10-12 were negligible or low (-0.5 ≤ cc ≤ 0.5.In the majority of cases, rupture of a cerebral aneurysm leads to delayed release of soluble TLR forms into CSF. sTLR2 and 4 seem to have minor role in human post-SAH inflammation due to delayed release kinetics and low levels of these protein.

    Full Text Available Ischemic stroke is associated with motor impairment and increased incidence of affective disorders such as anxiety/clinical depression. In non-stroke populations, successful management of such disorders and symptoms has been reported following diet supplementation with long chain omega-3-polyunsaturated-fatty-acids (PUFA. However, the potential protective effects of PUFA supplementation on affective behaviours after experimentally induced stroke and sham surgery have not been examined previously. This study investigated the behavioural effects of PUFA supplementation over a six-week period following either middle cerebral artery occlusion or sham surgery in the hooded-Wistar rat. The PUFA diet supplied during the acclimation period prior to surgery was found to be associated with an increased risk of acute haemorrhage following the reperfusion component of the surgery. In surviving animals, PUFA supplementation did not influence infarct size as determined six weeks after surgery, but did decrease omega-6-fatty-acid levels, moderate sickness behaviours, acute motor impairment and longer-term locomotor hyperactivity and depression/anxiety-like behaviour.

  18. MR imaging of fetal cerebral anomalies

    International Nuclear Information System (INIS)

    Background. Prenatal diagnosis of fetal brain anomalies relies mainly upon ultrasonography. However, even in the most experienced hands, the technique has limitations for some difficult diagnoses. MRI is an excellent imaging modality for the paediatric and adult brain. Objective. To assess the value of prenatal MRI when a cerebral anomaly was detected by US and where the prognosis depended on the identification of other anomalies undetectable by US, or where fetuses were at risk for a CNS lesion even when the US was normal. Materials and methods. Four hundred prenatal MRI examinations were performed since 1988, and confirmed by postnatal follow-up or pathological examination. Two-thirds of the examinations were performed after 25 weeks of gestation, one-third between 21 and 26 weeks. Fetal immobilisation was obtained by maternal premedication with flunitrazepam, administered orally 1 h before the examination. The examinations were performed on 1.5 T scanners using one or two surface coils. Results. Prenatal MRI allowed the diagnosis of serious unsuspected lesions such as neuronal migration disorders, ischaemic and haemorrhagic lesions and the abnormalities observed in tuberous sclerosis. It helped to characterise ventricular dilatation and anomalies of the corpus callosum and of the posterior fossa. Conclusions. MRI is a valuable complementary tool when prenatal US is incomplete, doubtful or limited. Prenatal MRI is particularly useful for the detection of ischaemic and haemorrhagic lesions, neuronal migration disorders and tuberous sclerosis lesions. Detection of these associated anomalies worsens the fetal prognosis, has medico-legal implications and modifies obstetric management. Normal prenatal MRI does not exclude an anomaly. (orig.)

    2012-02-01

    Substandard care is reported to occur in a large number of cases of major obstetric haemorrhage (MOH). A prospective audit was carried out by a multidisciplinary team at our hospital over a one year period to assess the quality of care (QOC) delivered to women experiencing MOH. MOH was defined according to criteria outlined in the Scottish Audit of Maternal Morbidity (SAMM). 31 cases were identified yielding an incidence of 3.5\\/1000 deliveries. The predominant causes were uterine atony 11 (35.4%), retained products of conception 6 (19.3%) and placenta praevia\\/accreta 6 (19.3%). Excellent initial resuscitation and monitoring was noted with a high level of senior staff input. Indicators of QOC compared favourably with the SAMM. Areas for improvement were identified. This pilot study demonstrates the feasibility of detailed prospective data collection in MOH in a busy Dublin obstetric unit with a view to developing a national audit. Standardization of definitions allows for international comparisons.

  2. Major lower intestinal haemorrhage: angiographic localisation and current management

    International Nuclear Information System (INIS)

    Thirty-four patients with major lower intestinal bleeding underwent emergency selective mesenteric angiography during a 6-year period. Angiography identified a bleeding site in 16 patients (47%). Diverticulosis, found in 22 patients (65%), and angiodysplasia, found in 4 (12%), were the most common causes of major colonic bleeding and originated more frequently from the right colon. Eight patients (24%) bled from less common sources. Radiological control of bleeding was unreliable with a significant complication rate. Fourteen of 16 patients with positive angiograms and 6 of 18 patients with negative angiograms required surgery for persistent major bleeding. Angiographic localisation of colonic bleeding allowed limited resection in 9 of 11 patients with control of haemorrhage in 8 (89%). Fourteen of 34 patients were managed non-operatively; of these 2 had minor recurrent bleeding. The overall mortality rate was 29%, the operative mortality rate 40% and the non-operative mortality rate 14%. A rational diagnostic approach is presented, emphasising the role of selective mesenteric angiography in the management and surgical strategy of major lower intestinal bleeding

  3. Dengue fever and dengue haemorrhagic fever in adolescents and adults.

    2012-05-01

    Dengue fever (DF) is endemic in tropical and subtropical zones and the prevalence is increasing across South-east Asia, Africa, the Western Pacific and the Americas. In recent years, the spread of unplanned urbanisation, with associated substandard housing, overcrowding and deterioration in water, sewage and waste management systems, has created ideal conditions for increased transmission of the dengue virus in tropical urban centres. While dengue infection has traditionally been considered a paediatric disease, the age distribution of dengue has been rising and more cases have been observed in adolescents and adults. Furthermore, the development of tourism in the tropics has led to an increase in the number of tourists who become infected, most of whom are adults. Symptoms and risk factors for dengue haemorrhagic fever (DHF) and severe dengue differ between children and adults, with co-morbidities and incidence in more elderly patients associated with greater risk of mortality. Treatment options for DF and DHF in adults, as for children, centre round fluid replacement (either orally or intravenously, depending on severity) and antipyretics. Further data are needed on the optimal treatment of adult patients. PMID:22668446

    Aim: To propose a new computed tomography (CT)-based classification system for non-aneurysmal subarachnoid haemorrhage (SAH), which predicts patients' discharge clinical outcome and helps to prioritize appropriate patient management. Methods and materials: A 5-year, retrospective, two-centre study was carried out involving 1486 patients presenting with SAH. One hundred and ninety patients with non-aneurysmal SAH were included in the study. Initial cranial CT findings at admission were correlated with the patients' discharge outcomes measured using the Modified Rankin Scale (MRS). A CT-based classification system (type 1-4) was devised based on the topography of the initial haemorrhage pattern. Results: Seventy-five percent of the patients had type 1 haemorrhage and all these patients had a good clinical outcome with a discharge MRS of {<=}1. Eight percent of the patients presented with type 2 haemorrhage, 62% of which were discharged with MRS of {<=}1 and 12% of patients had MRS 3 or 4. Type 3 haemorrhage was found in 10%, of which 16% had good clinical outcome, but 53% had moderate to severe disability (MRS 3 and 4) and 5% were discharged with severe disability (MRS 5). Six percent of patients presented with type 4 haemorrhage of which 42% of the patients had moderate to severe disability (MRS 3 and 4), 42% had severe disability and one-sixth of the patients died. Highly significant differences were found between type 1(1a and 1b) and type 2 (p = 0.003); type 2 and type 3 (p = 0.002); type 3 and type 4 (p = 0.001). Conclusion: Haemorrhages of the type 1 category are usually benign and do not warrant an extensive battery of clinical and radiological investigations. Type 2 haemorrhages have a varying prognosis and need to be investigated and managed along similar lines as that of an aneurysmal haemorrhage with emphasis towards radiological investigation. Type 3 and type 4 haemorrhages need to be extensively investigated to find an underlying cause.

    Cerebral microangiopathies are a very heterogenous group of diseases characterized by pathological changes of the small cerebral vessels. They account for 20 - 30 % of all ischemic strokes. Degenerative microangiopathy and sporadic cerebral amyloid angiography represent the typical acquired cerebral microangiopathies, which are found in over 90 % of cases. Besides, a wide variety of rare, hereditary microangiopathy exists, as e.g. CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), Fabrys disease and MELAS syndrome (Mitochondrial myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like episodes).

    Intracranial haemorrhage (ICH) in term newborns has been increasingly recognised but the occurrence in late preterm infants and the clinical presentation are still unclear. To investigate the appearance of intracranial haemorrhage at MRI in a cohort of infants born at 34 weeks' gestation or more and to correlate MRI findings with neonatal symptoms. We retrospectively reviewed neonatal brain MRI scans performed during a 3-year period. We included neonates ≥34 weeks' gestation with intracranial haemorrhage and compared findings with those in babies without intracranial haemorrhage. Babies were classified into three groups according to haemorrhage location: (1) infratentorial, (2) infra- and supratentorial, (3) infra- and supratentorial + parenchymal involvement. Intracranial haemorrhage was observed in 36/240 babies (15%). All of these 36 had subdural haemorrhage. Sixteen babies were included in group 1; 16 in group 2; 4 in group 3. All infants in groups 1 and 2 were asymptomatic except one who was affected by intraventricular haemorrhage grade 3. Among the infants in group 3, who had intracranial haemorrhage with parenchymal involvement, three of the four (75%) presented with acute neurological symptoms. Uncomplicated spontaneous vaginal delivery was reported in 20/36 neonates (56%), vacuum extraction in 4 (11%) and caesarean section in 12 (33%). Babies with intracranial haemorrhage had significantly higher gestational age (38 ± 2 weeks vs. 37 ± 2 weeks) and birth weight (3,097 ± 485 g vs. 2,803 ± 741 g) compared to babies without intracranial haemorrhage and were more likely to be delivered vaginally than by caesarian section. Mild intracranial haemorrhage (groups 1 and 2) is relatively common in late preterm and term infants, although it mostly represents an incidental finding in clinically asymptomatic babies; early neurological symptoms appear to be related to parenchymal involvement.

    Objective: To study the frequency of causes of primary postpartum hemorrhage (PPH) in women managed in a tertiary care Hospital. material and Methods: The study was conducted in the department of Obstetrics and Gynecology, Unit - 1, Lady Willingdon Hospital King Edward Medical University, Lahore from July 2013 to December 2013. All the women having postpartum haemorrhage after vaginal delivery in the labour room or referred with primary postpartum haemorrhage were included in the study and were evaluated to see the frequency of postpartum haemorrhage as well as the causes of PPH in women being treated in a tertiary care unit. Results: During the study period 1344 women delivered in unit I and 250 patients developed postpartum haemorrhage giving frequency of primary postpartum haemorrhage 18.60%. Majority of the women 29.6% (n = 74) were between 26 - 30 years of age, mean and SD was 28.43 ± 4.76 years. The gestation of 55.2% (n = 138) patients was between 37 - 40 weeks. The frequency of postpartum haemorrhage in booked women during antenatal period was recorded as 25.2% (n = 63) while 74.8% (n = 187) were not booked in any health facility. Among patients who developed PPH, uterine atony was the most common cause 57.6% (n = 144), followed by genital tract teats which was 29.2% (n = 73). The rest of the causes of PPH were retained placenta in 10% (n = 25), uterine rupture in 3.6% (n = 9) and uterine inversion in 1.6% (n = 4). Conclusions: Postpartum haemorrhage is still a leading but preventable cause of maternal morbidity and mortality in our country due to under utilization of health facilities, the major cause is uterine atony followed by perineal tears.

    Full Text Available Abstract Background Aneurysmal subarachnoid haemorrhage (aSAH is a devastating event with a frequently disabling outcome. Our aim was to develop a prognostic model to predict an ordinal clinical outcome at two months in patients with aSAH. Methods We studied patients enrolled in the International Subarachnoid Aneurysm Trial (ISAT, a randomized multicentre trial to compare coiling and clipping in aSAH patients. Several models were explored to estimate a patient's outcome according to the modified Rankin Scale (mRS at two months after aSAH. Our final model was validated internally with bootstrapping techniques. Results The study population comprised of 2,128 patients of whom 159 patients died within 2 months (8%. Multivariable proportional odds analysis identified World Federation of Neurosurgical Societies (WFNS grade as the most important predictor, followed by age, sex, lumen size of the aneurysm, Fisher grade, vasospasm on angiography, and treatment modality. The model discriminated moderately between those with poor and good mRS scores (c statistic = 0.65, with minor optimism according to bootstrap re-sampling (optimism corrected c statistic = 0.64. Conclusion We presented a calibrated and internally validated ordinal prognostic model to predict two month mRS in aSAH patients who survived the early stage up till a treatment decision. Although generalizability of the model is limited due to the selected population in which it was developed, this model could eventually be used to support clinical decision making after external validation.

    Intracranial haemorrhage (ICH) is a common cause of morbidity and mortality in haemophilic patients. The overall incidence of ICH has been reported to range from 2.2% to 7.5% in patients with haemophilia. From 1987 to 2001, 401 haemophilic patients from the Serviço de Hemofilia, Disciplina de Hematologia e Hemoterapia, Universidade Federal de São Paulo were evaluated. The episodes of ICH were documented by CT scan and the anatomic location, clinical presentation, relationship to trauma and clinical factors, including the presence of HIV infection and the presence of inhibitor, were reviewed. Among 401 haemophilic patients, 45 ICH episodes in 35 (8.7%) patients with age ranging from 4 days to 49 years (mean 10.6 years) were observed. A history of recent trauma was documented in 24 (53.3%) cases. Seventeen (37.8%) episodes occurred in more than one site of bleeding, 12 (26.7%) were subdural, seven (15.5%) subarachnoid, four (8.9%) epidural, two (4.4%) intracerebral and one (2.2%) intraventricular. The most frequent symptoms were headache and drowsiness. All patients were submitted to replacement therapy and neurosurgical intervention was performed in eight (17.8%) patients. Despite the treatment, three (8.6%) haemophilia A patients died due to the ICH event and three presented late sequelae. The most important aspect of ICH management is the early replacement therapy in haemophilic patients. This prompt treatment will increase the chances of a better prognosis. Another impact measure consists in the administration of the deficient coagulation factor after every head trauma, even when considered minor.

    Aim: To assess the published evidence on the endovascular treatment of non-variceal upper gastrointestinal haemorrhage. Materials and methods: An Ovid Medline search of published literature was performed (1966-2009). Non-English literature, experimental studies, variceal haemorrhage and case series with fewer than five patients were excluded. The search yielded 1888 abstracts. Thirty-five articles were selected for final analysis. Results: The total number of pooled patients was 927. The technical and clinical success of embolization ranged from 52-100% and 44-100%, respectively. The pooled mean technical/clinical success rate in primary upper gastrointestinal tract haemorrhage (PUGITH) only, trans-papillary haemorrhage (TPH) only, and mixed studies were 84%/67%, 93%/89%, and 93%/64%, respectively. Clinical outcome was adversely affected by multi-organ failure, shock, corticosteroids, transfusion, and coagulopathy. The anatomical source of haemorrhage and procedural variables did not affect the outcome. A successful embolization improved survival by 13.3 times. Retrospective comparison with surgery demonstrated equivalent mortality and clinical success, despite embolization being applied to a more elderly population with a higher prevalence of co-morbidities. Conclusions: Embolization is effective in this very difficult cohort of patients with outcomes similar to surgery.

    Full text: Stroke remains a devastating clinical event with few therapeutic options. In patients with acute stroke, we studied the cerebral perfusion and metabolic patterns with {sup 15}O-CO{sub 2} or H{sub 2}O and {sup 15}O-O{sub 2} positron emission tomography and correlated these findings to the clinical background. Forty three patients underwent 45 studies 0-23 days post-stroke (mean 7 days). Fifteen patients showed luxury perfusion (Group A), 10 had matched low perfusion and metabolism (B) and 3 showed mixed pattern including an area of misery perfusion (C). Seventeen showed no relevant abnormality (D) and there were no examples of isolated misery perfusion. Twelve of the 15 in Group A had either haemorrhagic transformation on CT, re-opening on angiography, or a cardioembolic mechanism. In contrast only 5/10 in Group B, 0/3 in Group C and 2/17 in Group D had these features. Although 7/10 in group B had moderate or large size infarcts on CT the incidence of haemorrhagic transformation was low (2/10) and significant carotid stenoses were more common in those studied (5/8) compared with the other groups. Misery perfusion was not seen beyond five days. Thus, luxury perfusion seems to be related to a cardio-embolic mechanism or reperfusion. Matched low perfusion and metabolism was associated with a low rate of haemorrhagic transformation despite a high incidence of moderate to large size infarcts. Misery perfusion is an early phenomenon in the evolution of ischaemic stroke.

Fifty-nine patients, 38 of whom were under 1 year of age, underwent cerebral angiography by means of femoral catheterization. All the patients had signs of increased intracranial pressure, seizures, focal cerebral signs, positive transillumination of the head, and or abnormal brain scan findings. A few patients who did not respond to systemic antibiotics as was expected were also evaluated by means of cerebral angiography. The following characteristic angiographic findings were observed in 18 cases of active meningitis: (1) A hasy appearance around the arteries (halo formation) between the late arterial and capillary phases. (2) Narrowing of the arteries in the basal cistern. This sometimes extended to the peripheral arteries. (3) Irregular caliber following the narrowing of arteries (in few cases). (4) Circulation time so slow that veins could be seen in the late arterial phase. (5) Halo formation around the anterior chroidal artery and the clear appearance of the choroid plexus in the venous phase (when the infectious process reached the choroid plexus). Cerebritis could be identified on the angiograms by two signs: (1) local swelling of the brain (mainly the temporal lobe) and (2) staining around the veins without any abnormal signs in the arterial phase (laminar staining). In conclusion, angiography is a meaningful test by which to determine the phase of meningitis and cerebritis. These two conditions should be treated based on valid information obtained by means of CSF examinations and neuroradiological tests, especially CT scan and cerebral angiography. (author)

    Extracorporeal Membrane Oxygenation (ECMO) has evolved as a treatment option for patients having potentially reversible severe respiratory failure who are deteriorating on conventional ventilation. During ECMO, systemic anticoagulation is needed to maintain patency of the circuit. Therefore, ongoing haemorrhage remains a relative contra-indication to ECMO as it can further increase the bleeding. There is only limited evidence available for the use of ECMO in patients with alveolar haemorrhage. Most of these patients did not receive any anticoagulation during ECMO. We describe our experience with a patient who received intravenous anticoagulation during ECMO for refractory hypoxemic respiratory failure due to Diffuse Alveolar Haemorrhage (DAH) associated with Granulomatosis polyangitis (Wegner's GPA). ECMO sustained life by maintaining gas exchange support and provided the time for the immunotherapy to be effective. We report the successful use of anticoagulation during ECMO in a patient with DAH.

    During the past decade outbreaks of a severe haemorrhagic disease caused by dengue viruses of multiple types have been reported in the Philippines, Thailand, Malaysia, Viet-Nam and eastern India. In many of these outbreaks chikungunya virus, a group A arbovirus, was simultaneously the cause of similar but probably milder disease. Both these viruses appear to be able to be able to produce classical dengue fever in some individuals and disease with haemorrhagic manifestations in others. Because of the growing public health importance and the progressive spread of this disease a unified review of its clinical and epidemiological features has been needed. This paper presents the history and salient clinical features of mosquito-borne haemorrhagic fever and summarizes recent epidemiological studies and current diagnostic and control methods.

    2016-01-01

    Introduction Microscopic study of the organization of the Subdural Haemorrhage (SDH) verified against the time period can help us in the determination of its age which has serious medico-legal implications. Very few studies concerning the dating of SDH are present in the literature. Aim This study was conducted for dating the early subdural haemorrhage by routine histopathological stains. Materials and Methods A prospective analytical study was conducted during July 2009 to December 2010. A total of 100 cases (50 males and 50 females) fulfilling the inclusion and exclusion criteria were included in this study. Routine histopathological staining of the subdural haematoma was done. Results Correlation between the frequency of a given histomorphological phenomenon and the length of the Post-Traumatic Interval (PTI) was evidential. All the histomorphological features, when correlated with PTI groups, were found to be statistically significant, except for Polymorphonuclear Leukocytes (PMN). Conclusion We concluded that routine histopathology was reliable in the dating of early subdural haemorrhages.

    The large hyperaemic foetal adrenal gland is vulnerable to vascular damage. This may occur in the neonatal period as a consequence of difficult labour, or its aetiology may not be apparent. The spectrum of presentation is considerable, ranging from asymptomatic to severe life-threatening intra-abdominal haemorrhage. The presentation of adrenal insufficiency may be delayed but the regenerative capacity of the adrenal is great, and most adrenal haemorrhage is not associated with significantly impaired function. Some reports showed that cholestatic hepatopathy with congenital hypopituitarism reversed by hydrocortisone treatment is considered in the context of the endocrine syndrome, probably as a consequence of the adrenal failure. We describe a case of bilateral adrenal haemorrhage with hepatitis syndrome and persistent hypoglycaemia in a newborn male with striking features of neonatal cholestasis and adrenal crisis.

  20. Comparative distribution of petechial haemorrhages as a function of aircraft cockpit geometry.

    1987-07-01

    One of the stresses to which aircrew are subjected in a modern highly manoeuvrable military aircraft is produced by high-speed turns; the resultant elevated G forces may cause petechial haemorrhages, particularly in the lower limbs. Since an aeroplane is an inconvenient laboratory, the mechanisms responsible for these haemorrhages are best investigated by elevated G forces produced in a human centrifuge on the ground, where a similar stress produces the same kind of haemorrhage. Such physical stimuli are in effect a modification of the normal terrestrial gravitational force (a force which under normal conditions is assumed to be +1 G) acting in a + Gz (head to foot) direction. The distribution of petechial haemorrhages is determined by a number of factors, including cockpit configuration. Differences in the distribution of petechial haemorrhages in the F-15 and F-16 aircraft (12 degrees tilt-back seat and 30 degrees tilt-back seat with elevation of the heel, respectively) lend an insight into those body areas where there is inadequate protection. The phenomenon usually begins to develop in healthy individuals at approximately +5 Gz (head to foot), with virtually everyone having petechial haemorrhages at +9 Gz. The kinetics of +Gz -induced petechiasis is interesting, because individuals develop an acclimatized resistance to these formations, whose exact aetiology is unknown; whether or not the petechiae are due to rupture of susceptible capillaries or to diapedesis is also unknown. Stasis and pooling of blood in the lower limbs play a specific role in the petechial formation; it is not only the +Gz stress, but also the protective equipment and techniques which determine the extent and magnitude of the petechiasis.(ABSTRACT TRUNCATED AT 250 WORDS)

  1. Pathogenesis of Intrapulmonary Haemorrhage in Dogs Exposed to Pulsed Fission-Spectrum Neutrons

    International Nuclear Information System (INIS)

    Previous comparison in this laboratory of tissue alterations in dogs produced by exposure to 250 kVp X-rays and pulsed fission-spectrum neutrons has shown general similarity of response. However, the lungs of animals exposed to fission-spectrum neutrons are considerably more susceptible to peribronchial and perivascular pulmonary haemorrhage. An attempt has been made to define the pathogenesis of this lesion by exposing five beagles to 400 rad (MAD) fast neutrons from a bare GODIVA-type reactor and serially sacrificing the animals at periodic intervals. Gross pathologic alterations consisting of occasional small peripheral-pulmonary haemorrhages were discernible at +5 d post-irradiation. These became progressively more numerous by the ninth day. The most striking changes occurred at +13 d, consisting of extensive perivascular haemorrhage around pulmonary-arterial branches from the hilum to the pleural suríace. The earliest histologic changes observed in the lungs occurred at +5 d, consisting of focal well-demarcated areas of alveolar congestion, swelling of capillary-endothelial cells and slight alveolar extravasation of red blood cells. These changes became more generalized by + 9 d and in addition there were focal areas of peribronchial extravasation of blood involving the right and left main-stem bronchi. Animals necropsied on the thirteenth day post-irradiation revealed extensive perivascular haemorrhage involving large and small pulmonaryarterial vessels. The blood appeared within the advential-connective tissue and periarterial-lymphatic spaces. Endothelial swelling was extremely marked in affected vessels, but the media appeared essentially unremarkable. Peribronchial haemorrhage was also present adjacent to affected pulmonary-arterial branches. The pathogenesis of these alterations appears to be related to primary endothelial damage produced by pulsed fission-spectrum neutrons. An additional contributing factor is probably thrombocytopenia as the number of

    2008-03-01

    Full Text Available Abstract Introduction Bleb needling is a recognised procedure in the management of patients with failing trabeculectomies. Suprachoroidal haemorrhage can occur as an unusual complication. We report a pseudophakic man who had early surgical intervention for this complication. This intervention may have contributed to the good recovery of his visual acuity and the minimum changes to his visual fields. Case presentation A 79-year-old pseudophakic man with chronic open angle glaucoma presented with further deterioration of his right visual field despite maximum medical therapy and a previous trabeculectomy. The right visual acuity was 6/9 with an intraocular pressure (IOP of 16 mmHg. Bleb needling with 5-fluouracil was performed in a standard manner. His postoperative IOP was 6 mmHg. Thirty-six hours later the visual acuity was reduced to hand movements and two large choroidal detachments where observed clinically, which progressed to suprachoroidal haemorrhages. Five days after the initial needling, the patient had complex surgery involving anterior chamber reformation, a bleb compression suture and drainage of the haemorrhagic suprachoroidal detachments. Subsequently, the patient had a right vitrectomy with endolaser following a vitreous haemorrhage. The final visual acuity was 6/9 with an intraocular pressure of 8 mmHg on travoprost and brinzolamide. The final visual field showed little change when compared with the pre-suprachoroidal haemorrhage visual field. Conclusion It is important to consider the possibility of delayed suprachoroidal haemorrhage as a complication in bleb needling, and early surgical intervention may be beneficial.

  3. Statins and cerebral hemodynamics

    2012-01-01

    HMG-CoA reductase inhibitors (statins) are associated with improved stroke outcome. This observation has been attributed in part to the palliative effect of statins on cerebral hemodynamics and cerebral autoregulation (CA), which are mediated mainly through the upregulation of endothelium nitric oxide synthase (eNOS). Several animal studies indicate that statin pretreatment enhances cerebral blood flow after ischemic stroke, although this finding is not further supported in clinical settings. Cerebral vasomotor reactivity, however, is significantly improved after long-term statin administration in most patients with severe small vessel disease, aneurysmal subarachnoid hemorrhage, or impaired baseline CA.

    We describe the radiological and pathological findings of two cases of calcific haemorrhagic bursitis, one involving the superficial infrapatellar bursa and the other the prepatellar bursa. It was the presence of dystrophic calcification within the lesion that suggested a mineralizing soft tissue sarcoma such as synovial sarcoma. As the radiographic and MR features of the two conditions can be similar but the appropriate management very different, rare calcifying haemorrhagic bursitis needs to be included in the differential diagnosis of masses adjacent to the knee joint showing calcification.

    2011-08-01

    Full Text Available In case of intracerebral haemorrhage (ICH during oral anticoagulant therapy (OAT it is mandatory to obtain the fast and complete normalisation of haemostasis, in order to minimise the risk of haematoma enlargement. Furthermore, if neurosurgery is requested, the immediate correction of haemostatic balance allows the execution of emergency intervention, thus reducing the risk of intra- and post-surgical haemorrhagic complications. Currently prothrombin complex concentrate (PCC in combination with vitamin K represents the gold standard treatment for patients with ICH during OAT. This treatment should be preferred to the administration of fresh frozen plasma (FFP in order to guarantee a fast and almost immediate normalisation of blood coagulation.

    Pelvic fractures carry a considerable risk for morbidity and mortality.Half or more of the early deaths in these patients have been attributed directly to haemorrhage.The transfusional requirements are four times higher for open pelvic fractures compared with a similar group of closed pelvic fractures.The loss of the tamponade effect by disruption of the pelvic soft tissues and the energy imparted play a central role in this potentially life threatening situation.We reported a case of open pelvic fracture in which persistent haemorrhage was stopped by giving recombinant activated coagulation factor Ⅶa as our last resort.

    2015-12-01

    Haemocoagulase is a snake venom protein derivative that is known to possess haemostatic activity. It is reported to minimise blood loss in orthopaedic, otorhinolaryngologic, and abdominal surgeries. The use of intravenous haemocoagulase in orthognathic surgery is unknown and not yet reported. The purpose of this trial is to study the efficacy of haemocoagulase in haemorrhage control in orthognathic surgery. Forty-six consecutive patients scheduled to undergo bi-maxillary orthognathic surgery within the time period of the study were recruited and randomized. They received either the study drug or placebo. All patients underwent operation with hypotensive anaesthesia. Intraoperative blood loss, operating time, drop in haemoglobin and haematocrit were the variables analysed in the study. Haemocoagulase caused an 11% (52 ml) reduction in blood loss in the study group (p = 0.01). There was no adverse reaction in any of the patients.

  16. Uterine artery embolization for the management of secondary postpartum haemorrhage associated with placenta accreta

    International Nuclear Information System (INIS)

    Aim: To evaluate the efficacy and safety of uterine artery embolization for the management of secondary postpartum haemorrhage associated with placenta accreta. Materials and methods: Between January 2005 and August 2011, 45 women with placenta accreta, which was discovered during delivery, were managed conservatively in Peking Union Medical College Hospital. They did not experience severe bleeding during delivery. Ten patients (mean age 31 ± 6.4 years) developed secondary postpartum haemorrhage and underwent uterine artery embolization. The complications, control of haemorrhage, and outcome of the placenta left inside the uterus were retrospectively reviewed. Results: All patients underwent transcatheter embolization of bilateral uterine arteries. The median time between delivery and uterine artery embolization was 11 days (range 3–76 days). The technical success rate of embolization was 100%. Bleeding was controlled in all patients during follow-up (11 ± 6.9 months; range 3–24 months), and no further bleeding occurred. One patient developed lower-extremity deep venous thrombosis after uterine artery embolization, and no other major complications occurred. The placentae that were left inside the uteri gradually decreased in size during follow-up, except in one case. Nine patients resumed normal menstruation. One patient subsequently became pregnant and had an uneventful intrauterine pregnancy carried to term. Conclusion: Uterine artery embolization is safe and effective for the management of secondary postpartum haemorrhage associated with placenta accreta.

    To examine the clinical and radiologic findings of patients with developmental venous anomaly (DVA) associated with intracranial haemorrhage but unrelated to cavernoma. Computed tomography (CT) was used to obtain intracranial images from seven patients ranging in age from 6 to 51 years. Magnetic resonance imaging (MRI) was then performed on six patients, and two patients were further examined via CT angiography. Finally, digital subtraction angiography (DSA) was performed to confirm the initial diagnosis. CT showed intraparenchymal supratentorial haemorrhage in all patients. The combined imaging modalities eventually confirmed a diagnosis of arterialised DVA in four patients and arterialised DVA associated with arteriovenus malformation (AVM) in three. Two patients were managed symptomatically, two underwent radiosurgery, one underwent surgery, one underwent combined embolisation plus radiosurgery and the remaining patient underwent combined embolisation plus surgery. Two patients died, one as a result of re-bleeding, and the other due to radiation necrosis. The mean follow-up period was 33 months (6 months to 6 years) for the remaining five patients with favourable outcome. DVA associated with intraparenchymal haemorrhage, but not related to cavernoma, was confirmed. Though very rare, DVA may present with non-cavernoma-related haemorrhage in the form of arterialised DVA or DVA with AVM. (orig.)

    The purpose of this retrospective study was to evaluate the role of transcatheter arterial embolization in the management of severe postpartum haemorrhage due to a ruptured pseudoaneurysm and to analyse the clinical symptoms that may suggest a pseudoaneurysm as a cause of postpartum haemorrhage. A retrospective search of our database disclosed seven women with severe postpartum haemorrhage in whom angiography revealed the presence of a uterine or vaginal artery pseudoaneurysm and who were treated using transcatheter arterial embolization. Clinical files were reviewed for possible clinical findings that could suggest pseudoaneurysm as a cause of bleeding. Angiography revealed extravasation of contrast material in five out of seven patients. Transcatheter arterial embolization allowed to control the bleeding in all patients and subsequently achieve vaginal suture in four patients with vaginal laceration. No complications related to transcatheter arterial embolization were noted. Only two patients had uterine atony, and inefficiency of sulprostone was observed in all patients. Transcatheter arterial embolization is an effective and secure technique for the treatment of severe postpartum haemorrhage due to uterine or vaginal artery pseudoaneurysm. Ineffectiveness of suprostone and absence of uterine atony should raise the possibility of a ruptured pseudoaneurysm. (orig.)

    AIM: To report a case of successful drainage of a large pre-macular haemorrhage using laser photo-disruption of the posterior hyaloid membrane. MATERIALS AND METHODS: A case report. RESULTS: A 47-year-old man presented acutely to our emergency department complaining of a 24-h history of sudden onset, painless and persistent loss of vision in his left eye. Immediately before noticing this loss of vision, he had been vomiting violently from excessive alcohol intake. The left visual acuity was counting fingers. Dilated fundoscopy of the left eye revealed a large pre-macular haemorrhage which was 14 disc diametres in size. Clotting investigations were normal. A diagnosis of valsalva retinopathy was made and the patient elected to receive a prompt neodymium-doped yttrium aluminium garnet (Nd:YAG) laser posterior hyaloidotomy as an outpatient. At 1 week follow-up, the haemorrhage had drained completely into the vitreous space revealing a healthy macula and the visual acuity had improved to 6\\/12 unaided. At 6-month follow-up the left visual acuity stabilised at 6\\/9 unaided. CONCLUSION: Nd:YAG laser posterior hyaloidotomy is a useful outpatient procedure for successful clearance of large pre-macular haemorrhages that offers patients rapid recovery of visual acuity and the avoidance of more invasive intraocular surgery.

    Natural infections of cattle associated with Listeria innocua have not been reported. This report describes the first case of cerebral listeriosis in a bull due to Listeria innocua. The animal presented neurological signs characterized by weakness, incoordination and recumbency. Histopathologic evaluation of brain tissue revealed multifocal microabscesses, perivascular lymphocytic cuffing, vasculitis, oedema and haemorrhages. All lesions extended from the medulla oblongata to the basal nuclei/parietal cortex area. Indirect immunohistochemistry labelled for Listeria sp. in the brain tissue, but not for Listeria monocytogenes, neurotropic Flaviviruses, BVDV, bovine Herpesvirus 1, Chlamydophila spp. and Histophilus somni. PCR was negative for ovine herpesvirus. L. innocua was isolated from brainstem and identified by biochemical tests (Camp and beta-hemolysis negative). Subsequently, the species was confirmed by a duplex PCR and minisequencing assays. L. innocua should be histologically considered as a differential diagnosis of thrombotic meningoencephalitis, malignant catarrhal fever and cerebral listeriosis due to L. monocytogenes in cattle.

    Full Text Available A 13-month-old, neutered, male Golden retriever presented with seizures and progressive depression. Clinical and neurological assessment was consistent with severe intracranial disease. The neurological condition progressively deteriorated and magnetic resonance imaging (MRI revealed the presence of a large, contrast-enhancing, space-occupying mass in the right cerebral hemisphere. Therapy with corticosteroids, mannitol and furosemide ameliorated the signs of depression and ataxia, but the owner elected euthanasia after 1 week. Post mortem examination of the brain confirmed the presence of a large haemorrhagic lesion in the right olfactory lobe, the histopathological appearance of which was consistent with cerebral cavernous haemangioma. This is the 1st case describing the MRI appearance of a cavernous haemangioma of the cerebrum in the veterinary literature.

  4. Unilateral cerebral polymicrogyria with ipsilateral cerebral hemiatrophy

    International Nuclear Information System (INIS)

    We evaluated six children in whom MR imaging showed unilateral cerebral polymicrogyria associated with ipsilateral cerebral atrophy and ipsilateral brain stem atrophy. The aim of this study was to clarify whether this disorder based on neuroimaging constitutes a new homogeneous clinical entity. The subjects were six children whose ages at the time of MR imaging ranged from 8 months to 11 years. Their clinical and MR features were analyzed. All of the children were born between 38 and 42 weeks gestation, without any significant perinatal events. Spastic hemiplegia and epilepsy were observed in all of the patients, and mental retardation was observed in four. The MR findings included unilateral cerebral polymicrogyria associated with ipsilateral cerebral hemiatrophy and ipsilateral brain stem atrophy in all patients. The ipsilateral sylvian fissure was hypoplastic in four patients. These patients showed relatively homogeneous clinical and neuroimaging features. Although the additional clinical features varied according to the site and the extent affected by the polymicrogyria, this disorder could constitute a new relatively homogeneous clinical entity.

    2006-08-01

    Cerebral metastases remain a common complication among patients with cancer. Historically, whole-brain radiotherapy has remained the standard of care, with surgery being reserved for selected cases. Recent advances have changed our practice, however. In particular, stereotactic radiosurgery has emerged as a vital treatment modality for this disease. In addition, chemotherapy, including temozolomide, topoisomerase inhibitors and antimetabolites, and treatment sensitizers, such as efaproxiral and motexafin gadolinium, are actively being assessed in clinical trials, and are likely to play an increasing role in the management of cerebral metastases in the future. Nonetheless, many uncertainties remain, such as the optimal combination and timing of therapeutics. As the arsenal of therapeutics expands, it will be increasingly important to select appropriate patients for a particular treatment paradigm. Understanding the efficacy and toxicity of treatment is essential to this task. PMID:16932601

    Full Text Available Abstract Background The mechanisms leading to death and functional impairments due to cerebral malaria (CM are yet not fully understood. Most of the knowledge about the pathomechanisms of CM originates from studies in animal models. Though extensive histopathological studies of the murine brain during CM are existing, alterations have not been visualized by scanning electron microscopy (SEM so far. The present study investigates the neuropathological features of murine CM by applying SEM. Methods C57BL/6J mice were infected with Plasmodium berghei ANKA blood stages. When typical symptoms of CM developed perfused brains were processed for SEM or light microscopy, respectively. Results Ultrastructural hallmarks were disruption of vessel walls, parenchymal haemorrhage, leukocyte sequestration to the endothelium, and diapedesis of macrophages and lymphocytes into the Virchow-Robin space. Villous appearance of observed lymphocytes were indicative of activated state. Cerebral oedema was evidenced by enlargement of perivascular spaces. Conclusion The results of the present study corroborate the current understanding of CM pathophysiology, further support the prominent role of the local immune system in the neuropathology of CM and might expose new perspectives for further interventional studies.

    2013-01-01

    Objective: To review the discoveries underpinning the introduction of cerebral PET scanning and highlight its modern applications. Background: Important discoveries in neurophysiology, brain metabolism, and radiotracer development in the post–World War II period provided the necessary infrastructure for the first cerebral PET scan. Methods: A complete review of the literature was undertaken to search for primary and secondary sources on the history of PET imaging. Searches were performed in PubMed, Google Scholar, and select individual journal Web sites. Written autobiographies were obtained through the Society for Neuroscience Web site at www.sfn.org. A reference book on the history of radiology, Naked to the Bone, was reviewed to corroborate facts and to locate references. The references listed in all the articles and books obtained were reviewed. Results: The neurophysiologic sciences required to build cerebral PET imaging date back to 1878. The last 60 years have produced an evolution of technological advancements in brain metabolism and radiotracer development. These advancements facilitated the development of modern cerebral PET imaging. Several key scientists were involved in critical discoveries and among them were Angelo Mosso, Charles Roy, Charles Sherrington, John Fulton, Seymour Kety, Louis Sokoloff, David E. Kuhl, Gordon L. Brownell, Michael Ter-Pogossian, Michael Phelps, and Edward Hoffman. Conclusions: Neurophysiology, metabolism, and radiotracer development in the postwar era synergized the development of the technology necessary for cerebral PET scanning. Continued use of PET in clinical trials and current developments in PET-CT/MRI hybrids has led to advancement in diagnosis, management, and treatment of neurologic disorders. PMID:23460618

    Directory of Open Access Journals (Sweden)

    Emeka B. Kesieme

    2012-01-01

    Full Text Available Gastric duplications are uncommon developmental abnormality reported to present with different clinical scenarios. We present a 2-1/2-year-old Nigerian female who started having intermittent massive lower gastrointestinal haemorrhage at 5 months of age. She subsequently developed a lower chest wall mass and enterocutaneous fistula. She was found to have gastric duplication with fistulous communication with the descending colon, spleen, and lower chest wall. To the best of our knowledge, this is the first paper on gastric duplication resulting in intermittent massive lower gastrointestinal bleeding mainly from splenic capsular erosion and fistula and enterocutaneous fistula resulting from erosion of anterior abdominal wall. Gastric duplication is hence an important rare cause of intermittent massive lower gastrointestinal haemorrhage and spontaneous enterocutaneous fistula in the paediatric population.

  20. The role of the histaminergic system in the central cardiovascular regulation in haemorrhagic hypotension.

    Science.gov (United States)

    Jochem, Jerzy; Kasperska-Zajac, Alicja

    2012-01-01

    The histaminergic system consists of neurons located in tuberomammillary nucleus of the posterior hypothalamus. It affects many functions of the central nervous system, including regulation of the brainstem cardiovascular center. In this paper, we present current review of the literature concerning the role of the histaminergic system in the cardiovascular regulation in haemorrhagic hypotension. Experimental studies demonstrate that in both, normotension and critical hemorrhagic hypotension, histamine, acting as a central neurotransmitter, evokes the pressor effect. Interestingly, increases in mean arterial pressure are significantly higher in hypovolaemic than in normovolaemic animals. Many lines of evidence support the hypothesis that in haemorrhagic shock, the histaminergic system is able to activate neural and humoral compensatory mechanisms involving the sympathetic nervous and renin-angiotensin systems, arginine vasopressin and proopiomelanocortin-derived peptides. We suggest that the histaminergic system could be a new target for treatment of hemorrhagic hypotension.

    A young pregnant Zambian woman was referred from a district hospital in South Zambia to the university teaching hospital, Lusaka with severe anaemia and ascites. The ascites had developed over a month and the woman was currently 15 weeks pregnant. Further workup revealed that the patient was HIV-positive and the ascitic tap showed haemorrhagic fluid. After being reviewed by multiple doctors, the cause of the haemorrhagic ascites remained unclear; therefore, the decision was made to do a laparotomy. The laparotomy revealed haemoperitoneum and a large cyst attached to the liver containing 5 L of bloodstained fluid. The histopathology report revealed features consistent with a giant haemangioma. There were many barriers to accessing optimum healthcare in this case. These included limited access to blood, poor communication resulting in the patient being unaware of her HIV status and lack of patient education about HIV. PMID:27473033

    Acute liver failure in neonates is rare and is frequently associated with an unfavourable outcome. There is no curative treatment other than liver transplantation. Screening for viral, metabolic, toxic or vascular disease is essential to assess the prognosis and to guide specific treatment. Hepatic haemorrhage in neonates is often associated with bacterial infection, trauma and coagulopathies. We present a unique case of neonatal acute liver failure and multifocal massive haemorrhagic intrahepatic lesions of traumatic origin, documented by US and MRI. The patient made a spontaneous recovery. Clinical, biological and imaging outcome was excellent despite the apparent severity of the initial features. The only possible aetiology was a difficult caesarean delivery for mild fetal macrosomia. (orig.)

    All around the world as well as in Bulgaria postpartal haemorrhage is a main reason of maternal death. The treatment of postpartal haemorrhage of which approximately 70% is caused by hypotony of the uterus is still a challenge for physician-obstetrician. In the following study we have used prostaglandin-Carboprost tromethamole (Prostin 15M) for treatment of this important obstetric pathology. One year investigation which includes 82 patients with hypotony during vaginal delivery or cesarian section. Results showed that the use of Carboprost tromethamole (Prostin 15M) in treatment of hypotony leads to fast and extended contraction of the uterus as well as significantly decreases blood loss and the necessity of haemotrasfusion.

    We present a case of bilateral adrenal haemorrhage (BAH) associated with heparin-induced thrombocytopaenia (HIT) in a 61-year-old man admitted to hospital for the treatment of Fournier's gangrene. He presented to hospital with scrotal swelling and fever, and developed spreading erythaema and a gangrenous scrotum. His scrotum was surgically debrided and intravenous broad-spectrum antibiotics were administered. Unfractionated heparin was given postoperatively for venous thromboembolism prophylaxis. The patient deteriorated clinically 8-11 days postoperatively with delirium, chest pain and severe hypertension followed by hypotension and thrombocytopaenia. Abdominal CT scan revealed bilateral adrenal haemorrhage. Antibodies to the heparin-platelet factor 4 complex were present. HIT-associated BAH was diagnosed and heparin was discontinued. Intravenous bivalirudin and hydrocortisone were started, with rapid improvement in clinical status. BAH is a rare complication of HIT and should be considered in the postoperative patient with unexplained clinical deterioration.

Injury to the developing brain that occurs either in utero or soon after birth can result in the motor, sensory, and cognitive deficits seen in cerebral palsy. Although the etiologies for cerebral palsy are variable, neuroinflammation plays a key role in the pathophysiology of the brain injury irrespective of the etiology. Currently, there is no effective cure for cerebral palsy. Nanomedicine offers a new frontier in the development of therapies for prevention and treatment of brain injury resulting in cerebral palsy. Nanomaterials such as dendrimers provide opportunities for the targeted delivery of multiple drugs that can mitigate several pathways involved in injury and can be delivered specifically to the cells that are responsible for neuroinflammation and injury. These materials also offer the opportunity to deliver agents that would promote repair and regeneration in the brain, resulting not only in attenuation of injury, but also enabling normal growth. In this review, the current advances in nanotechnology for treatment of brain injury are discussed with specific relevance to cerebral palsy. Future directions that would facilitate clinical translation in neonates and children are also addressed.

    2012-06-09

    BACKGROUND AND PURPOSE: Intracranial haemorrhage in neurosarcoidosis (NS-ICH) is rare, poorly understood and the diagnosis of NS may not be immediately apparent. METHODS: The clinical features of three new NS-ICH cases are described including new neuropathological findings and collated with cases from a systematic literature review. RESULTS: Cases: (i) A 41-year-old man with headaches, hypoandrogenism and encephalopathy developed a cerebellar haemorrhage. He had neuropathological confirmation of NS with biopsy-proven angiocentric granulomata and venous disruption. He responded to immunosuppressive therapy. (ii) A 41-year-old man with no history of hypertension was found unconscious. A subsequently fatal pontine haemorrhage was diagnosed. Liver biopsy revealed sarcoid granulomas. (iii) A 36-year-old man with raised intracranial pressure headaches presented with a seizure and a frontal haemorrhage. Hilar lymph node biopsy confirmed sarcoidosis, and he was treated successfully. Systematic Review: Twelve other published cases were identified and collated with our cases. Average age was 36 years and M:F = 2.3:1; 46% presented with neurological symptoms and 31% had CNS-isolated disease. Immediate symptoms of ICH were acute\\/worsening headache or seizures (60%). ICH was supratentorial (62%), infratentorial (31%) or subarachnoid (7%). 40% had definite NS, 53% probable NS and 7% possible NS (Zajicek criteria). Antigranulomatous\\/immunosuppressive therapy regimens varied and 31% died. CONCLUSIONS: This series expands our knowledge of the pathology of NS-ICH, which may be of arterial or venous origin. One-third have isolated NS. Clinicians should consider NS in young-onset ICH because early aggressive antigranulomatous therapy may improve outcome.

  20. Clinical Neuroimaging of cerebral ischemia

    Notice points in clinical imaging of cerebral ischemia are reviewed. When cerebral blood flow is determined in acute stage of cerebral embolism (cerebral blood flow SPECT), it is important to find area of ischemic core and ischemic penumbra. When large cortex area is assigned to ischemic penumbra, thrombolytic therapy is positively adapted, but cautious correspondence is necessary when ischemic core is recognized. DWI is superior in the detection of area equivalent to ischemic core of early stage, but, in imaging of area equivalent to ischemic penumbra, perfusion image or distribution image of cerebral blood volume (CBV) by MRI need to be combined. Luxury perfusion detected by cerebral blood flow SPECT in the cases of acute cerebral embolism suggests vascular recanalization, but a comparison with CT/MRI and continuous assessment of cerebral circulation dynamics were necessary in order to predict brain tissue disease (metabolic abnormality). In hemodynamic cerebral ischemia, it is important to find stage 2 equivalent to misery perfusion by quantification of cerebral blood flow SPECT. Degree of diaschisis can indicate seriousness of brain dysfunction for lacuna infarct. Because cerebral circulation reserve ability (perfusion pressure) is normal in all areas of the low cerebral blood flow by diaschisis mechanism, their areas are easily distinguished from those of hemodynamic cerebral ischemia.

The patient′s age ranged between 28 and 84 years. Motor signs on the nonhemiplegic side were present in 17 patients in the form of increased tone (10, hyperreflexia (13 and extensor plantar response (10. Sixteen of these patients had severe weakness on the hemiplegic side. Most of the patients had putaminal haemorrhage (13 and thalamic and lobar haemorrhage was seen in 2 patients each. The motor dysfunction on the nonhemiplegic side correlated with midline shift but not with the size of haematoma. CMCT findings correlated with motor signs on the nonhemiplegic side in 6 patients. In the patients without any signs on the nonhemiplegic side, CMCT was normal. Out of 17 patients with motor dysfunction on the nonhemiplegic side 9 revealed improvement in CMCT at 1 month followup. The patients with CMCT abnormalities on the nonhemiplegic side either died (2 or had poor outcome (9. Motor dysfunction on the nonhemiplegic side may be due to tentorial herniation and suggests a poor outcome.

    Clinical and angiographic findings in migraine are briefly reviewed in relation to cerebral hemodynamic changes shown by regional cerebral blood flow (rCBF) studies. Three cases of migraine studied by the intracarotid xenon 133 method during attacks are reported. In classic migraine, with typical...... prodromal symptoms, a decrease in cerebral blood flow has been demonstrated during the aura. Occasionally, this flow decrease persists during the headache phase. In common migraine, where such prodromata are not seen, a flow decrease has not been demonstrated. During the headache phase of both types...... of migraine, rCBF has usually been found to be normal or in the high range of normal values. The high values may represent postischemic hyperemia, but are probably more frequently secondary to arousal caused by pain. Thus, during the headache phase rCBF may be subnormal, normal or high. These findings do...

    2015-09-01

    In addition to cerebrovascular resistance (CVR) zero flow pressure (ZFP), effective cerebral perfusion pressure (CPPe) and the resistance area product (RAP) are supplemental determinants of cerebral blood flow (CBF). Until now, the interrelationship of PaCO2-induced changes in CBF, CVR, CPPe, ZFP, and RAP is not fully understood. In a controlled crossover trial, we investigated 10 anesthetized patients aiming at PaCO2 levels of 30, 37, 43, and 50 mm Hg. Cerebral blood flow was measured with a modified Kety-Schmidt-technique. Zero flow pressure and RAP was estimated by linear regression analysis of pressure-flow velocity relationships of the middle cerebral artery. Effective cerebral perfusion pressure was calculated as the difference between mean arterial pressure and ZFP, CVR as the ratio CPPe/CBF. Statistical analysis was performed by one-way RM-ANOVA. When comparing hypocapnia with hypercapnia, CBF showed a significant exponential reduction by 55% and mean VMCA by 41%. Effective cerebral perfusion pressure linearly decreased by 17% while ZFP increased from 14 to 29 mm Hg. Cerebrovascular resistance increased by 96% and RAP by 39%; despite these concordant changes in mean CVR and Doppler-derived RAP correlation between these variables was weak (r=0.43). In conclusion, under general anesthesia hypocapnia-induced reduction in CBF is caused by both an increase in CVR and a decrease in CPPe, as a consequence of an increase in ZFP.

  8. Cerebral fat embolism

    International Nuclear Information System (INIS)

    A case of cerebral fat embolism is reported. A 18-year-old patient with multiple bone fractures was in semiconma immediately after an injury. Brain CT showed no brain swelling or intracranial hematoma. Hypoxemia and alcoholemia were noted on admission, which returned to normal without improvement of consciousness level. In addition, respiratory symptoms with positive radiographic changes, tachycardia, pyrexia, sudden drop in hemoglobin level, and sudden thrombocytopenia developed. These symptoms were compatible with Gurd's criteria of systemic fat embolism. Eight days after injury, multiple low density areas appeared on CT and disappeared within the subsequent two weeks, and subdural effusion with cerebral atrophy developed. These CT findings were not considered due to cerebral trauma. Diagnosis of cerebral fat embolism was made. The subdural effusion was drained. Neurologic and pulmonary recoveries took place slowly and one month following the injury the patient became alert and exhibited fully coordinated limb movement. The CT scans of the present case well corresponded with hitherto reported pathological findings. Petechiae in the white matter must have developed on the day of injury, which could not be detected by CT examination. It is suggested that some petechial regions fused to purpuras and then gradually resolved when they were detected as multiple low density areas on CT. CT in the purpuras phase would have shown these lesions as high density areas. These lesions must have healed with formation of tiny scars and blood pigment which were demonstrated as the disappearance of multiple low density areas by CT examination. Cerebral atrophy and subsequent subdural effusion developed as a result of demyelination. The patient took the typical clinical course of cerebral fat embolism and serial CT scans served for its assessment. (author)

    Subchorionic haemorrhage in the 1st trimester of pregnancy can be seen in some patients and the significance of it is controversial. In this study, subchorionic haemorrhage was found to be significantly associated with increased risk of miscarriage and IUGR. On the other hand, we did not see a significant relation between pre-term labour and subchorionic haemorrhage. We hope these findings will help clinicians in their practice about pregnancy follow-up.

    Introduction Pre-eclampsia is a major complication of pregnancy, globally responsible for 60 000 maternal deaths per year, and far greater numbers of fetal losses. There is no definitive treatment other than delivery. A drug that can quench the disease process could be useful to treat early onset pre-eclampsia, as it could allow pregnancies to safely continue to a gestation where fetal outcomes are significantly improved. We have generated preclinical data to show esomeprazole, a proton pump inhibitor used for gastric reflux, has potent biological effects that makes it a worthwhile therapeutic candidate. Esomeprazole potently decreases soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin secretion from placenta and endothelial cells, and has biological actions to mitigate endothelial dysfunction and oxidative stress. Methods and analysis We propose undertaking a phase II, double blind, randomised controlled clinical trial to examine whether administering 40 mg esomeprazole daily may prolong gestation in women with early onset pre-eclampsia. We will recruit 120 women (gestational age of 26+0 to 31+6 weeks) who will be randomised to receive either esomeprazole or an identical placebo. The primary outcome will be the number of days from randomisation to delivery. Secondary outcomes include maternal, fetal and neonatal composite and individual outcomes. Maternal outcomes include maternal death, eclampsia, pulmonary oedema, severe renal impairment, cerebral vascular events and liver haematoma or rupture. Neonatal outcomes include neonatal death within 6 weeks after the due date, intraventricular haemorrhage, necrotising enterocolitis and bronchopulmonary dysplasia. We will examine whether esomeprazole can decrease serum sFlt-1 and soluble endoglin levels and we will record the safety of esomeprazole in these pregnancies.

    Two serovars of Pasteurella multocida, B:2 and E:2, have been reportedly associated with haemorrhagic septicaemia (HS), a peracute and devastating disease mainly affecting cattle and water buffaloes. We multilocus sequence typed (MLST) 64 isolates of P. multocida including 55 associated with HS and...... the est gene. A new HS-est-RT-PCR (est indicating the target gene) specifically detected ST122, ST63, ST147 and ST162 associated with HS. The new HS-est-RT-PCR did not detect strains of ST151 with capsular type D isolated from pigs that were found positive with a previously published HS PCR detection...... method. The new HS-est-RT-PCR represents a fast and specific detection of the specific types of P. multocida involved in HS.

  17. Recurrent cerebral thrombosis

    International Nuclear Information System (INIS)

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

    Envenoming by the West African saw-scaled viper, Echis ocellatus resembles that of most vipers, in that it results in local blistering, necrosis and sometimes life-threatening systemic haemorrhage. While effective against systemic envenoming, current antivenoms have little or no effect against local tissue damage. The major mediators of local venom pathology are the zinc-dependant snake venom metalloproteinases (SVMPs). The high degree of structural and functional homology between SVMPs and their mammalian relatives the matrix metalloproteinases (MMPs) suggests that substrate/inhibitor interactions between these subfamilies are likely to be analogous. In this study, four recently developed MMP inhibitors (MMPIs) (Marimastat, AG-3340, CGS-270 23A and Bay-12 9566) are evaluated in addition to three metal ion chelators (EDTA, TPEN and BAPTA) for their ability to inhibit the haemorrhagic activities of the medically important E. ocellatus venom and one of its haemorrhagic SVMPs, EoVMP2. As expected, the metal ion chelators significantly inhibited the haemorrhagic activities of both whole E. ocellatus venom and EoVMP2, while the synthetic MMPIs show more variation in their efficacies. These variations suggest that individual MMPIs show specificity towards SVMPs and that their application to the neutralization of local haemorrhage may require a synthetic MMPI mixture, ensuring that a close structural component for each SVMP is represented.

    Brain blood vessels contain muscarinic receptors that are important for cerebral blood flow (CBF) regulation, but whether a cholinergic receptor mechanism is involved in the exercise-induced increase in cerebral perfusion or affects cerebral metabolism remains unknown. We evaluated CBF and cerebral...... metabolism (from arterial and internal jugular venous O(2), glucose and lactate differences), as well as the middle cerebral artery mean blood velocity (MCA V(mean); transcranial Doppler ultrasound) during a sustained static handgrip contraction at 40% of maximal voluntary contraction (n = 9) and the MCA V......(mean) during ergometer cycling (n = 8). Separate, randomized and counterbalanced trials were performed in control (no drug) conditions and following muscarinic cholinergic receptor blockade by glycopyrrolate.

  2. The role of arterial embolization in controlling pelvic fracture haemorrhage: A systematic review of the literature

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of emergency transcatheter arterial embolization (TAE) in controlling retroperitoneal arterial haemorrhage associated with unstable pelvic fractures. Methods: A systematic review of the English literature yielded 21 eligible studies published from 1979 to 2010. Evaluation of clinical and methodological heterogeneity was based on recording certain descriptive characteristics in the component studies. Statistical heterogeneity was detected using Cochran chi-square and I square tests and, when absent, a pooled estimate of effect size for each outcome of interest was calculated. The principal outcomes of interest were efficacy rate of TAE to control intrapelvic bleeding, mortality rates and frequency of associated complications. Results: All component studies were assigned a low to moderate quality score. Methodological and clinical heterogeneity was evident across component studies, but not strongly associated with the observed results. The efficacy rate of TAE ranged from 81 to 100%, while the frequency of repeat TAE for effective control of haemorrhage was 10% (95% CI: 7–13%, range: 0–19%). TAE was associated with an overall mortality ranging from 7 to 47%, and a 0–25% mortality due to intrapelvic bleeding (pooled estimate of effect size: 6%, 95% CI: 4–8%). A very low rate of associated complications were recorded in the component studies (pooled estimate of effect size: 1.1%, 95% CI: 0.1–2.1%). Conclusion: TAE is an efficient acute intervention for controlling severe arterial bleeding related to pelvic trauma with a low complication rate. Repeat of the procedure is occasionally necessary before the effective haemorrhage control.

    Until the beginning of this decade, the genetic characterization of rabbit haemorrhagic disease virus (RHDV) from Iberian Peninsula had revealed the existence of two genogroups, G1 and sporadically G6. In 2010, the new emerging rabbit haemorrhagic disease variant, RHDV2 or RHDVb, was described in France, from where it has rapidly spread throughout Europe, including Iberian Peninsula countries. Nevertheless, although cases of rabbit haemorrhagic disease (RHD) have been reported in the Canary Islands, a Spanish archipelago located 100km off the coast of Morocco, no genetic characterization of RHDV had been carried out. Consequently, in order to identify the circulating RHDV strains in this archipelago, liver samples of six farm rabbits and fifteen wild rabbits were collected from several areas of the largest island, Tenerife, and analyzed for the presence of RHDV by antigen capture double antibody sandwich ELISA. In case of positive ELISA result, we amplified and sequenced two fragments of the vp60 gene, which were concatenated for phylogenetic purposes. The sequences analysis revealed the presence of RHDV2 in both farm and wild rabbits from several areas of Tenerife. This result constitutes the first finding of RHDV2 in the Canary Islands. These RHDV2 strains found in Tenerife shared two exclusive SNPs that have not been observed in the rest of RHDV2 strains. The identification of RHDV2 and the absence of classic RHDV strains in this study suggest that RHDV2 may be replacing classic strains in Tenerife, as has been also proposed in Iberian Peninsula, France and Azores. Given the proximity of the Canary Islands to the African continent, this result should raise awareness about a possible dispersal of RHDV2 from the Canary Islands to the North of Africa.

    Full Text Available BACKGROUND Even though there are many innovative methods to make classes more interesting and effective, in my department, topics are taught mainly by didactic lectures. This study attempts to compare the effectiveness of manikin demonstration and didactic lectures in teaching conservative management of post-partum haemorrhage. OBJECTIVE To compare the effectiveness of manikin demonstration and didactic lectures in teaching conservative management of postpartum haemorrhage. MATERIALS AND METHODS This is an observational study. Eighty four ninth-semester MBBS students posted in Department of Obstetrics and Gynaecology, Government Medical College, Kottayam were selected. They were divided into 2 groups by lottery method. Pre-test was conducted for both groups. Group A was taught by manikin demonstration. Group B was taught by didactic lecture. Feedback response from the students collected after demonstration class was analysed. Post-test was conducted for both the groups after one week. Gain in knowledge of both the groups were calculated from pre-test and post-test scores and compared by Independent sample t test. RESULTS The mean gain in knowledge in group A was 6.4 when compared to group B which is 4.3 and the difference was found to be statistically significant. All of the students in group A felt satisfied and more confident after the class and wanted more topics to be taken by demonstration. CONCLUSION Manikin demonstration class is more effective in teaching conservative management of post-partum haemorrhage and this method can be adopted to teach similar topics in clinical subjects.

Estos síndromes se caracterizan por tener una sintomatología común: los trastornos motores. Algunos autores prefieren manejar términos como "encefalopatía fija", "encefalopatías no evolutivas". Se mencionan la utilidad de programas de intervención temprana y métodos especiales de rehabilitación, así como el manejo de las deficiencias asociadas como la epilepsia, deficiencia mental, trastornos del lenguaje, audición, visión, déficit de la atención que mejoran el pronóstico de manera significativa. El pronóstico también depende de la gravedad del padecimiento y de las manifestaciones asociadas.The term cerebral palsy (CP, is used for a great number of clinical neurological syndromes. The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the nonevolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations.

    A 33-year-old female with a longstanding history of seizures was admitted to our hospital with subarachnoid haemorrhage (SAH). Computed tomography (CT), magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) depicted a vascular fat-containing lesion overlying a right frontal cortical polymicrogyria. The diagnosis of angiolipoma was established. Conservatory management was undertaken with full recovery. She has been followed for 5 years since, with neither re-bleeding nor morphologic change of the lesion. This is a rare intracranial lesion, with only 11 intracranial angiolipomas published in the literature, and is the first case reported which is associated with SAH caused by this lesion. (orig.)

    Full Text Available The diagnosis, work-up, and treatment of sudden sensorineural hearing loss and sudden vestibular loss vary widely between units. With the increasing access to both magnetic resonance imaging and objective vestibular testing, our understanding of the various aetiologies at hand is increasing. Despite this, the therapeutic options are limited and without a particularly strong evidence base. We present a rare, yet increasingly diagnosed, case of intralabyrinthine haemorrhage (ILH together with radiological, audiological, and vestibular test results. Of note, this occurred spontaneously and has shown partial recovery in all the mentioned modalities.

    The present study aimed to determine the incidence of primary postpartum haemorrhage (PPH) after vaginal birth at an Australian tertiary hospital, and to investigate risk factors for primary PPH at this hospital. A case-control study of women delivering vaginally at a tertiary hospital from February to June 2003 was performed. Demographic, antenatal, intrapartum, treatment and outcome data were abstracted from patient records. The study population comprised 125 cases and 125 controls, with a primary PPH rate of 12.1 per 100 vaginal births. Risk factors on multivariate analysis were past history of PPH, second stage labour > 60 min, forceps delivery, and incomplete placenta/ragged membranes. PMID:15904450

    We present the case of a 72-year-old woman who developed right hemiparesis following a left frontal intraparenchymal haemorrhage. Three months following initial presentation, the patient noted poorly localised right lower quadrant pain. Following extensive investigations, a diagnosis of heterotopic ossification of the hip was made. We discuss the aetiology and pathogenesis of this uncommon entity, and discuss its relationship to ipsilateral neurological injury. The link with neurological injury can result in a delayed and atypical presentation. Early recognition and treatment are important for those caring for patients with acquired neurological deficits, and permit improved patient outcomes. PMID:26243751

    Canine parvovirus type 2 (CPV-2), the aetiological agent of haemorrhagic enteritis in dogs, includes three antigenic variants, types 2a, 2b and 2c. CPV-2c has been detected initially in Italy and subsequently in Vietnam. We report the first identification of this novel antigenic variant in Spain, where it caused an outbreak of fatal enteritis in basset hound pups in association with canine coronavirus type I and type II. We suggest that this new antigenic variant of CPV-2 could spread throughout Europe and that there is a subsequent need to update current CPV vaccines. PMID:17123424

    The relationship between impairment of consciousness and quantitative cerebral blood flow (CBF) was investigated. The mean CBF of the whole brain was measured by the Patlak-plot method using technetium-99m hexamethylpropylene amine oxime single-photon emission tomography ({sup 99m}Tc-HMPAO SPET) in patients with the following diseases: cerebral infarction, intraparenchymal haemorrhage, subarachnoid haemorrhage, brain tumour and cerebral contusion. The clinical symptoms were evaluated according to the severity of impaired consciousness, aphasia and dementia. Four hundred and eighty-five CBF measurements were performed. Patients with alert consciousness showed an age-related decline in mean CBF. Patients with aphasia showed a significant reduction in mean CBF compared with those without aphasia. Impaired consciousness was proportional to reduction in mean CBF regardless of types of pathology, and the size of lesion did not influence the mean CBF. Patients with dementia showed a significant reduction in mean CBF proportional to the severity of dementia. The quantitative measurement of CBF using {sup 99m}Tc-HMPAO SPET is reliable in clinical evaluations. (orig.) With 3 tabs., 10 refs.

    2012-02-01

    Traumatic brain injury and subarachnoid haemorrhage are important causes of morbidity and mortality in the developed world. There is a large body of evidence that demonstrates that both conditions may adversely affect pituitary function in both the acute and chronic phases of recovery. Diagnosis of hypopituitarism and accurate treatment of pituitary disorders offers the opportunity to improve mortality and outcome in both traumatic brain injury and subarachnoid haemorrhage. In this article, we will review the history and pathophysiology of pituitary function in the acute phase following traumatic brain injury and subarachnoid haemorrhage, and we will discuss in detail three key aspects of pituitary dysfunction which occur in the early course of TBI; acute cortisol deficiency, diabetes insipidus and SIAD.

    2011-01-01

    Hepatitis-associated aplastic anaemia (HAAA) is an uncommon but distinct variant of aplastic anaemia in which pancytopenia and bone marrow failure appears 2-3 months after an acute attack of hepatitis. Although bilateral vision loss may rarely be the initial presentation of aplastic anaemia, no such report is known in HAAA. Here the authors report such a case presenting with large premacular subhyaloid haemorrhages secondary to severe anaemia and thrombocytopenia. Anaemic hypoxic damage to the vessel wall together with increased cardiac output and low platelet counts are interacting causal factors in the development of bleeding. Though these haemorrhages are benign and usually improve spontaneously, the presence of blood may cause permanent macular changes before it resolves. Posterior hyaloidotomy enabled rapid resolution of premacular subhyaloid haemorrhage thereby restoring vision and preventing need for vitreo-retinal surgery. These patients should be advised to refrain from valsalva manoeuvres, ocular rubbing and vigorous exercise to prevent ocular morbidity. PMID:22674943

TES intervention caused increasing of blood flow rate of brain: arteria cerebri anterior OR=40.504(95%CI,4.399-372.918), arteria cerebri media OR=30.376(95% CI,7.123-129.539), arteria cerebri posterior OR=7.398(95% CI,4.909- 11.148), vertebral artery OR=14.085(95%CI,4.696-42.249) and basilar artery OR=15.543(95% CI.3.356-72.000). The increased efficient of averaged blood flow rate was about 40.5, 30.4, 7.4, 14.1 and 15.5 times to the control groups. Conclusion: The result of meta analysis indicate that TES can increase the blood flow rate and blood flow volume of each arterial in brain roundly and remarkably, maybe it can direct the use of physical factor treatment in clinic.%目的:通过meta分析,探讨经颅电刺激对大脑平均血流速度的影响.方法:通过MEDLINE、EMBASE和CBMdise等数据库检索国内外已发表相关文献.选择治疗组为药物治疗加双乳突部位经颅电刺激,对照组为药物治疗的随机对照试验.由2位评价者分别按上述检索策略收集资料,按纳入标准人选,采用Comprehensive Meta Analysis V2.0软件对大脑平均血流速度进行meta分析.结果:共有8个临床随机对照试验,包括570例受试者纳入分析.经颅电刺激干预使大脑前动脉OR=40.504(95%CI,4.399-372.918)

  19. Cerebral localization in antiquity.

    Fragments of neurology can be found in the oldest medical writings in antiquity. Recognizable cerebral localization is seen in Egyptian medical papyri. Most notably, the Edwin Smith papyrus describes hemiplegia after a head injury. Similar echoes can be seen in Homer, the Bible, and the pre-Hippocratic writer Alcmaeon of Croton. While Biblical writers thought that the heart was the seat of the soul, Hippocratic writers located it in the head. Alexandrian anatomists described the nerves, and Galen developed the ventricular theory of cognition whereby mental functions are classified and localized in one of the cerebral ventricles. Medieval scholars, including the early Church Fathers, modified Galenic ventricular theory so as to make it a dynamic model of cognition. Physicians in antiquity subdivided the brain into separate areas and attributed to them different functions, a phenomenon that connects them with modern neurologists. PMID:20183203

    Previous studies performed by positron emission tomography and Transcranial Doppler (TCD) found a different cerebral activation during musical stimuli in musicians compared to non-musicians. The aim of our study is to evaluate by means of TCD, possible different pattern of cerebral activation during the performance of different musical tasks in musicians, non-musicians and lyrical singers. Our findings show a left hemispheric activation in musicians and a right one in non-musicians. Preliminary data on lyrical singers' activation patterns need further confirmation with a larger population. These data could be related to a different approach to music listening in musicians (analytical) and non-musicians who are supposed to have an emotional approach to music. PMID:10942664

The angiographic picture in one of the three cases was similar to that previously described in association with amphetamine abuse and pseudoephedrine overdose, both substances being chemically and pharmacologically similar to phenylpropanolamine. The study suggests that the arterial change responsible for symptoms may be due to spasm rather than arteriopathy. 14 references, 5 figures.

    Insomnia is defined as difficulty with the initiation, maintenance, duration, or quality of sleep that results in the impairment of daytime functioning, despite adequate opportunity and circumstances for sleep. In most countries approximately every third inhabitant has insomnia. Insomnia can be classified as primary and secondary. The pathogenesis of primary insomnia is unknown, but available evidence suggests a state of hyperarousal. Insomnia secondary to other causes is more common than primary insomnia. Cerebral hypoperfusion can be the cause of insomnia in some cases. In such patients the cerebral blood flow should be improved using parenteral vascular therapy. If insomnia persists despite treatment, then therapy for primary insomnia should be instituted using benzodiazepine-receptor agonists such as Zolpidem, Zopiclone, or Zaleplon. In those cases Midazolam cannot be used for the treatment of insomnia due to its marked negative effect on cerebral blood flow. In Hungary there is a need to organize multidisciplinary Insomnia Clinics because insomnia is more than a disease, it is a public health problem in this century. PMID:17988972

  7. Cerebral oxygenation and hyperthermia

    2014-03-01

    Full Text Available Hyperthermia is associated with marked reductions in cerebral blood flow (CBF. Increased distribution of cardiac output to the periphery, increases in alveolar ventilation and resultant hypocapnia each contribute to the fall in CBF during passive hyperthermia; however, their relative contribution remains a point of contention, and probably depends on the experimental condition (e.g. posture and degree of hyperthermia. The hyperthermia-induced hyperventilatory response reduces arterial CO2 pressure (PaCO2 causing cerebral vasoconstriction and subsequent reductions in flow. During supine passive hyperthermia, the majority of recent data indicate that reductions in PaCO2 may be the primary, if not sole, culprit for reduced CBF. On the other hand, during more dynamic conditions (e.g. hemorrhage or orthostatic challenges, an inability to appropriately decrease peripheral vascular conductance presents a condition whereby adequate cerebral perfusion pressure may be compromised secondary to reductions in systemic blood pressure. Although studies have reported maintenance of pre-frontal cortex oxygenation (assessed by near-infrared spectroscopy during exercise and severe heat stress, the influence of cutaneous blood flow is known to contaminate this measure. This review discusses the governing mechanisms associated with changes in CBF and oxygenation during moderate to severe (i.e. 1.0°C to 2.0°C increase in body core temperature levels of hyperthermia. Future research directions are provided.

    1992-11-01

    A thirty-year-old male patient suffered subarachnoidal haemorrhage from an angioma positioned in the cranio-cervical transition. After rebleeding twice the patient developed a hydrocephalus internus malresorptivus and excessive natriuresis and polyuria, accompanied by depressed renin activity and extremely low aldosterone plasma levels. Neither fluid restriction and sodium substitution, nor administration of hydro-chlorothiazide/indomethacin affected natriuresis and polyuria. It was only after treatment with fludrocortisone-acetate/hydrocortisone that hyponatraemia and polyuria were resolved. At the same time a ventriculo-peritoneal shunt was applied. Differential diagnosis excluded the syndromes of inadequate antidiuretic hormone secretion, renal and cerebral diabetes insipidus, osmotic receptor hypofunction, chronic renal dysfunction and tubular necrosis. Natriuresis and polyuria developed under dexamethasone therapy. Since patient history, physical examination and laboratory criteria could not explain the electrolyte and fluid imbalance, this might be attributed to the hydrocephalus. Similar disturbances have been reported from other patients with intracranial disorders. Mechanical pressure exercised on the hypothalamus might cause the disturbance of fluid and sodium balance. Assuming a cerebral salt wasting syndrome, a putative natriuretic factor coming from the brain or an imbalance in the cerebral renin-angiotensin-system, as described in rats and dogs, must be discussed.

    Full Text Available The association between the progestin only pill used for treatment of menstrual disorders and cerebral venous sinus thrombosis (CVST has rarely been reported in the literature. This report describes a case of cerebral venous thrombosis following intake of norethisterone for menorrhagia secondary to polycystic ovary syndrome in a young woman with undiagnosed underlying hyperhomocysteinemia. A 24 year old married woman presented with acute onset of headache, vomiting and right focal seizures. MRI Cerebral venogram and CT Brain revealed thrombosed anterosuperior segment of superior sagittal sinus and haemorrhagic infarct in right frontoparietal region. The risk factors were acquired hyperhomocysteinemia, polycystic ovary syndrome and norethisterone for menorrhagia. The patient was treated with low molecular weight heparin, followed by warfarin, vitamin B12, vitamin B6 and folic acid. She made a total recovery. Although venous thrombosis is usually linked to the ingestion of estrogen, rather than progestogen, this case illustrates that patients who are prescribed progestogen only pills for gynaecological disorders may develop thrombosis, especially if they have predisposing metabolic disorders.

    LENUS (Irish Health Repository)

    Egan, Aoife M

    2012-01-31

    INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

    To evaluate the results of emergency embolisation in acute arterial bleeding of the gastrointestinal tract with a liquid polyvinyl alcohol copolymer from two centres. We retrospectively analysed 16 cases (15 patients) of acute arterial bleeding of the gastrointestinal tract where emergency embolotherapy was performed by using the copolymer when acute haemorrhage was not treatable with endoscopic techniques alone. Cause of haemorrhage and technical and clinical success were documented. Arterial embolotherapy was successful in all 16 cases. The technical success rate was 100%. The cause of bleeding was pancreatitis in four, graft-versus-host disease (GVHD) of the colon in three, malignancy in three, angiodysplasia in two, ulcer in two and panarteritis no dosa and trauma in one each. There were no procedure-related complications. No bowel necrosis occurred because of embolisation. In 13 cases, the patients were discharged in good condition (81%); the three patients with GVHD died because of the underlying disease. The copolymer seems to have great potential in embolotherapy of acute arterial gastrointestinal bleeding. In our series none of the patients had rebleeding at the site of embolisation and no clinically obvious bowel necrosis occurred. (orig.)

    Full Text Available This study investigated if environmental factors had an effect on the incidence of epistaxis related to exercise-induced pulmonary haemorrhage (EIPH among racehorses in southern Africa. Data covering the period 1986-2001 and involving 778 532 race runs were analysed. This included the following information : date of race, age, sex, name of breeder, trainer, distance, jockey, state of going, weight carried, racing centre and altitude. Veterinarians employed by the Jockey Club suspended officially entered horses that presented with epistaxis (frank bleeding from the nostrils after racing. On-course endoscopy is not performedas a standard practice at any southern African racetrack. Epistaxis was identified in 1287 horses (0.165 %. More horses presented with EIPH-related epistaxis (a at sea level, (b from May to October, (c when older (> 3 years, (d after 1995, (e on Fridays and Sundays, and (f more in geldings than in mares or entire males. No association could be established between epistaxis and breeder, trainer, distance run, jockey, state of going and weight carried. It is concluded that the frequency of EIPH-related epistaxis is associated with altitude, winter and spring, sex and age. It is suggested that racing at lower altitudes may increase the probability of exercise-induced pulmonary haemorrhage.

    In the treatment of postpartum haemorrhage from uterine atony, uterine compression sutures, such as the B-Lynch suture and its modifications have a role with the advantage of preservation of the uterus for fertility. There is however, a risk that apposition of the anterior and posterior walls of the uterus will impede drainage of lochia, resulting in undesirable complications. We undertook a five-year retrospective study of all women who underwent uterine compression sutures at the KK Women's and Children's Hospital, between 2008 and 2012. In total, 23 women had uterine compression sutures during the study period, of which, nineteen women managed to conserve their uterus. Our complication rate was 25%, which included persistent vaginal discharge, pyometra and endometritis. There were three conceptions, with two successful pregnancies. Our study shows uterine compression suture to be a safe and effective alternative to avoid hysterectomy with preservation of fertility at the time of major postpartum haemorrhage. The outcome of subsequent pregnancies is reassuring. PMID:24678816

  14. Nitric oxide decreases intestinal haemorrhagic lesions in rat anaphylaxis independently of mast cell activation

    1997-01-01

    Full Text Available The purpose of this study is to assess the role of nitric oxide (NO in the intestinal lesions of passive anaphylaxis, since this experimental model resembles necrotizing enterocolitis. Sprague-Dawley rats were sensitized with IgE anti-dinitrophenol monoclonal antibody. Extravasation of protein-rich plasma and haemorrhagia were measured in the small intestine. Plasma histamine was measured to assess mast cell activation. The effect of exogenous NO on the lesions was assessed by using two structurally unrelated NO-donors: sodium nitroprusside and S-nitroso-Nacetyl-penicillamine (SNAP. An increased basal production of NO was observed in cells taken after anaphylaxis, associated with a reduced response to platelet-activating factor, interleukin 1beta, and IgE/DNP-bovine serum albumin complexes. The response to bacterial lipopolysaccharide and dibutyryl cyclic adenosine monophosphate (AMP was enhanced 24 h after challenge, but at earlier times was not significantly different from that observed in controls. Treatment with either sodium nitroprusside or SNAP produced a significant reduction of the haemorrhagic lesions, which are a hallmark of rat anaphylaxis. The extravasation of protein-rich plasma was not influenced by NO-donors. The increase of plasma histamine elicited by the anaphylactic challenge was not influenced by SNAP treatment. NO-donors protect intestinal haemorrhagic lesions of rat anaphylaxis by a mechanism apparently independent of mast cell histamine release.

  15. Severe gastric variceal haemorrhage due to splenic artery thrombosis and consecutive arterial bypass

    Directory of Open Access Journals (Sweden)

    Wasmuth Hermann E

    2011-06-01

    Full Text Available Abstract Background Upper gastrointestinal haemorrhage is mainly caused by ulcers. Gastric varicosis due to portal hypertension can also be held responsible for upper gastrointestinal bleeding. Portal hypertension causes the development of a collateral circulation from the portal to the caval venous system resulting in development of oesophageal and gastric fundus varices. Those may also be held responsible for upper gastrointestinal haemorrhage. Case presentation In this study, we describe the case of a 69-year-old male with recurrent severe upper gastrointestinal bleeding caused by arterial submucosal collaterals due to idiopathic splenic artery thrombosis. The diagnosis was secured using endoscopic duplex ultrasound and angiography. The patient was successfully treated with a laparoscopic splenectomy and complete dissection of the short gastric arteries, resulting in the collapse of the submucosal arteries in the gastric wall. Follow-up gastroscopy was performed on the 12th postoperative week and showed no signs of bleeding and a significant reduction in the arterial blood flow within the gastric wall. Subsequent follow-up after 6 months also showed no further gastrointestinal bleeding as well as subjective good quality of life for the patient. Conclusion Submucosal arterial collaterals must be excluded by endosonography via endoscopy in case of recurrent upper gastrointestinal bleeding. Laparoscopic splenectomy provides adequate treatment in preventing any recurrent bleeding, if gastric arterial collaterals are caused by splenic artery thrombosis.

    2000-06-01

    The study was designed to determine the cardiovascular effects of histamine administered intracerebroventricularly (icv) in a rat model of volume-controlled haemorrhagic shock. The withdrawal of approximately 50% of total blood volume resulted in the death of all control saline icv treated animals within 30 min. Icv injection of histamine produced a prompt dose-dependent (0.1-100 nmol) and long-lasting (10-100 nmol) increase in mean arterial pressure (MAP), pulse pressure (PP) and heart rate (HR), with a 100% survival of 2h after treatment (100 nmol). The increase in MAP and HR after histamine administration in bled rats in comparison to the normovolaemic animals was 2.7-3.3- and 1.3-3.6-fold higher, respectively. Pretreatment with chlorpheniramine (50 nmol icv), H1 receptor antagonist, inhibited the increase in MAP, PP, HR and survival rate produced by histamine, while chlorpheniramine given alone had no effect. Neither ranitidine (50 nmol icv), H2 histamine receptor antagonist, nor thioperamide (50 nmol icv), H3 receptor blocker, influenced the histamine action, however, when given alone, both evoked the pressor effect with elongation of survival time. It can be concluded that histamine administered icv reverses the haemorrhagic shock conditions, and histamine H1 receptors are involved.

    2002-03-01

    Viral haemorrhagic fevers (VHF) have attracted the attention of the medical world and general public for many reasons, some based in reality and more on misinformation. They are amongst the highest profile infections in the public mind, because they are thought to be highly infectious and to kill most of their victims in a dramatic way (1,2). To add to the intrigue, mysteries remain about the source of some of the viruses involved. They emerge and re-emerge in many countries, most recently Ebola in Uganda in 2000 (3) and Gabon in 2001/02 (4), and Congo Crimean Haemorrhagic Fever (CCHF) in Kosovo (5) and Pakistan in 2001 (6). Large outbreaks have affected populations in endemic areas, living mainly in inaccessible areas or refugee camps where living conditions are very difficult. Poorly resourced medical facilities have played a role in amplifying transmission and infection control measures have been difficult or virtually impossible to establish. These viruses are likely to remain a threat until the reservoir is identified and as long as endemic areas are afflicted with ecological change, poverty and social instability. Recent events since September 11 2001 remind us of their potential to be used as weapons, and that fear can present a risk to public health. PMID:12631941

    This study aims to investigate the clinical significance of post-interventional cerebral hyperdensities (PCHD) after endovascular mechanical thrombectomy in acute ischaemic stroke. Data of 102 consecutive patients who received post-interventional CT scans within 4.5 h after mechanical thrombectomy were analysed retrospectively. Sixty-two of 102 patients (60.8 %) had PCHD on their post-interventional CT scans. The most common site of PCHD was the basal ganglia. PCHD were persisting in 13 of 62 patients (21.0 %), and transient in the remaining 49 patients (79.0 %) within 24 h. Four patients with PCHD and four patients without PCHD suffered from parenchymal haemorrhage. Neither ASA nor Clopidogrel, Tirofiban or rtPA were risk factors for PCHD. Final infarction size was congruent with or bigger than areas of PCHD in 93.3 % of cases in our series. PCHD was not a risk factor for parenchymal haemorrhage in our series. The occurrence of PCHD was strongly related to the prior presence of infarction. PCHD was also a strong predictor for final infarction size. (orig.)

    1975-01-01

    In 120 patients with atherosclerosis, complicated in 43 patients by a haemorrhagic, in 47 patients by an ischaemic, and in 30 patients by a transient cerebral insult, phase analysis of platelet aggregation was performed by the turbidimetric method according to Born with graphic recording according to O'Brien. An increase in the platelet activity was found in ischaemic insult, manifesting itself by the occurrence of spontaneous aggregationin 60% of the cases, an acceleration of ADP-induced aggregation, and the second aggregation phase in all patients examined. A direct correlation was revealed between the secondary aggregation and the intensity of spontaneous and of ADP-induced aggregation, and the possibility of a transformation of the spontaneous into the secondary aggregation of platelets was demonstrated. Haemorrhagic insults were characterized by the absence of spontaneous and secondary aggregation and by the suppression of ADP-induced aggregation. In a transient insult, the mean values of the aggregatogram items did differ from normal. In vitro, the role of increased permeability of platelet membranes in the mechanism triggering off spontaneous aggregation and the second phase of ADP-induced aggregation was documented.

    Cerebral malformations are usually described following the different steps in development. Disorders of neurulation (dysraphisms), or diverticulation (holoprosencephalies and posterior fossa cysts), and total commissural agenesis are usually diagnosed in utero. In contrast, disorders of histogenesis (proliferation-differentiation, migration, organization) are usually discovered in infants and children. The principal clinical symptoms that may be a clue to cerebral malformation include congenital hemiparesis, epilepsy and mental or psychomotor retardation. MRI is the imaging method of choice to assess cerebral malformations. (orig.)

    Cerebral cavernous malformation (CCM) in infants tends to have genetic predisposition. These cavernomas have a progressive course of events and associated neurological symptoms with increase in age. They most commonly present with seizure and syndrome of increased intracranial pressure comprising of headache, vomiting and focal neurological signs. We describe a case of a 7-month-old infant who presented with an acute onset of right facial paralysis with a background of familial CCM. The CT and MRI scan revealed fresh haemorrhage in the right cerebellar and pontine cavernomas with surrounding oedema and no evidence of obstructive hydrocephalus. These two cavernomas re-bled in a week duration causing episodes of incessant crying and irritability. After discussing the pros and cons of treatment, owing to stable clinical status, the patient is currently been managed conservatively.

    We studied the pulsatile component of cerebral circulation with transcephalic electrical impedance (delta Z) in six preterm newborns, three of whom had severe cerebral bleeding, peri-intraventricular haemorrhage (PIVH). The transcephalic electrical impedance delta Z signal, ECG, arterial blood pressure, (aBP) and respirogram were recorded on analogue magnetic tape for 30 min. Artefact-free stationary segments (lasting for 2 min) of the four signals were digitised. A digital multivariate autoregressive (MAR) model was used to study frequency-specific variability in the signals and to quantify interrelations between the variabilities of delta Z, HR, aBP and respiratory signals. MAR modelling describes a system where all the signals simultaneously explain each other. The inherent variability of delta Z was lower and the influences of respiration and aBP on delta Z significantly greater in infants with severe PIVH than in controls. These changes were observed at high frequencies corresponding to respiration and heart rate. This may be interpreted as a marker of pressure passivism in the cerebral circulation following PIVH. We conclude that in preterm babies the application of MAR modelling, together with transcephalic impedance, may be a new, helpful and quantitative method for the study of simultaneous interrelations between variables of cerebral and systemic circulations and respiration.

    Full Text Available The study was conducted to investigate the platelet increasing property of Carica papaya leaves juice (CPLJ in patients with dengue fever (DF. An open labeled randomized controlled trial was carried out on 228 patients with DF and dengue haemorrhagic fever (DHF. Approximately half the patients received the juice, for 3 consecutive days while the others remained as controls and received the standard management. Their full blood count was monitored 8 hours for 48 hours. Gene expression studies were conducted on the ALOX 12 and PTAFR genes. The mean increase in platelet counts were compared in both groups using repeated measure ANCOVA. There was a significant increase in mean platelet count observed in the intervention group (P<0.001 but not in the control group 40 hours since the first dose of CPLJ. Comparison of mean platelet count between intervention and control group showed that mean platelet count in intervention group was significantly higher than control group after 40 and 48 hours of admission (P<0.01. The ALOX 12 (FC  =  15.00 and PTAFR (FC  =  13.42 genes were highly expressed among those on the juice. It was concluded that CPLJ does significantly increase the platelet count in patients with DF and DHF.

    Cytidine 5'-diphosphocholine (CDP-choline) is an endogenously synthesized mononucleotide which exerts a variety of physiological effects by altering central cholinergic transmission. Administered intracerebroventricularly (i.c.v.) or intravenously, it reverses haemorrhagic hypotension in rats, apparently by the activation of central cholinergic receptors. The study was undertaken to investigate the involvement of the central histaminergic system in CDP-choline-mediated reversal of haemorrhagic hypotension. Experiments were carried out in male ketamine/xylazine-anaesthetised Wistar rats subjected to haemorrhagic hypotension of 20-26 mmHg. CDP-choline (2 micromol; i.c.v.) administered at 5 min of critical hypotension produced a long-lasting pressor effect with increases in mean arterial pressure (MAP), heart rate (HR), and renal, hindquarters and mesenteric blood flows, resulting in a 100% survival at 2 h. The action was accompanied by approximately a 26% increase in extracellular histamine concentration at the posterior hypothalamus, as measured by microdialysis. Cardiovascular effects mediated by CDP-choline were almost completely blocked by pretreatment with H(1) receptor antagonist chlorpheniramine (50 nmol; i.c.v.), but not with H(2) receptor blocker ranitidine (25 nmol; icv) or H(3)/H(4) receptor antagonist thioperamide (50 nmol; i.c.v.). In conclusion, the present results show that he central histaminergic system, through the activation of H(1) histaminergic receptors, is involved in CDP-choline-induced resuscitating effect in haemorrhage-shocked rats.

    Leptin, acting centrally as a neuromodulator, induces the activation of the sympathetic nervous system, which may lead to a pressor action in normotensive animals. In haemorrhagic shock, leptin administered intracerebroventricularly (icv.) evokes the resuscitating effect, with long-lasting rises in mean arterial pressure (MAP) and heart rate (HR), subsequent increase in peripheral blood flows, and a 100% survival at 2 h. Since leptin is able to activate histaminergic neurons, and centrally acting histamine also induces the resuscitating effect with the activation of the sympathetic nervous system, in the present study, we investigated an involvement of the histaminergic system in leptin-evoked cardiovascular effects in haemorrhagic shock. The model of irreversible haemorrhagic shock, with MAP decreased to and stabilised at 20 - 25 mmHg, has been used. Leptin (20 μg) given icv. at 5 min of critical hypotension evoked 181.5% increase in extracellular hypothalamic histamine concentration during the first 10 min after injection. Rises in MAP, HR and renal, mesenteric and hindquarters blood flows induced by leptin were inhibited by icv. pre-treatment with histamine H1 receptor antagonist chlorpheniramine (50 nmol). In contrast, there was no effect of H2, H3 and H4 receptor antagonists ranitidine (25 nmol), VUF 5681 (25 nmol) and JNJ 10191584 (25 nmol), respectively. In conclusion, the histaminergic system is involved in centrally-acting leptin-induced resuscitating effect in haemorrhagic shock in rats.

    Leptospirosis is a zoonotic infection associated with severe diseases such as leptospirosis pulmonary haemorrhage syndrome (LPHS). The cause of pulmonary haemorrhage is unclear. Understanding which mechanisms and processes are involved in LPHS will be important in treatment regimens under development for this life-threatening syndrome. In the present study, we evaluated 30 lung specimens from LPHS patients and seven controls using histology and immunohistochemistry (detection of IgM, IgG, IgA and C3) in order to describe the pathological features associated with this syndrome. Immunoglobulin deposits were detected on the alveolar surface in 18/30 LPHS patients. Three staining patterns were observed for the immunoglobulins and C3 in the lung tissues of LPHS patients: AS, delicate linear staining adjacent to the alveolar surface, which was indicative of a membrane covering the luminal surface of type I and II pneumocyte cells; S, heterogeneous staining which was sporadically distributed along the alveolar septum; and IA, weak, focal intra-alveolar granular staining. Human LPHS is associated with individual and unique histological patterns that differ from those of other causes of pulmonary haemorrhage. In the present study, it was found that the linear deposition of immunoglobulins (IgA, IgG and IgM) and complement on the alveolar surface may play a role in the pathogenesis of pulmonary haemorrhage in human leptospirosis.

    Full Text Available OBJECTIVE: The mean platelet volume (MPV is a biomarker of platelet function and activity. The influence of platelet function disorders on the aetiology of intracerebral haemorrhages (ICH and mortality is not clear yet. The purpose of this study is to investigate the change in the MPV values in patients with ICH and to observe its influence on mortality in a retrospective manner. METHODS: Sixty-six patients with intracerebral haemorrhage (32 males, 34 females; mean age: 61.9± 16.9 were enrolled in the study. Patients with ICH were divided into two groups as those who died within the first 10 days and those who survived. The MPV values and the haematoma volumes were compared between the groups. Also, the MPV values and platelet counts of the patients with ICH were compared with the values of healthy volunteers from similar age and sex groups (27 males, 17 females; mean age: 59.9 ±3.2. RESULTS: The MPV values of the patients with ICH measured within 24 hours following the intracerebral haemorrhage (8.33 ± 1.27 fl/mL were statistically significantly higher than the MPV values of the control group (7.76 ± 1.14 fl/mL (p=0.018. The platelet counts of the patients with ICH also measured within the first 24 hours (235.8±94.9 x103/mL were statistically significantly lower than the platelet counts of the control group (279.1 ± 94.9 x103/mL (p=0.022. No statistically significant difference in terms of the MPV values and platelet counts was observed between the patients with ICH who died within the first 10 days and those who survived (p>0.05. However, the difference observed in the haematoma volume between the patients with ICH who died within the first 10 days (31.1 ±33.7 ml and those who survived (8.7± 13.4 ml was statistically significant (p<0.001. No correlation was found between the haematoma volume and the MPV value in the patients with ICH. CONCLUSION: The increase observed in the mean platelet volume in patients with ICH may point to a

  18. Cerebral hemodynamics in moyamoya disease

    International Nuclear Information System (INIS)

    Rebuild-up phenomenon, an electroencephalographic pathological finding in moyamoya disease, was evaluated in the context of dynamic changes in cerebral circulation after hyperventilation. Sequential functional angiography after hyperventilation, measurement of cerebral blood flow (CBF) by the outflow method, and Kr-81m single photon emission tomography were employed for clarification of the sequential dynamic changes in cerebral circulation after hyperventilation. In most cases there was a persistent decrease in CBF even after arterial carbon dioxide tension (PaCO2) had been normalized, which suggests that the response of the cerebral circulation to the changes in PaCO2 is delayed. Moreover, this feature was most prominent in the superficial layer of the cerebrum. For the most part, coincidence and synchronization were documented between rebuild-up and the delayed response of the cerebral circulation. These findings indicate that the delayed CBF response to hyperventilation contributes pathogenetically to rebuild-up in moyamoya disease. (author)

    Full Text Available The medicinal value of hydrogen (H 2 was ignored prior to research illustrating that inhalation of 2% H 2 can significantly decrease the damage of cerebral ischemia/reperfusion caused by oxidative stress via selective elimination of hydroxyl freebase (OH and peroxynitrite anion (ONOOˉ. Subsequently, there have been numerous experiments on H 2 . Most research and trials involving the mechanisms underlying H 2 therapy show the effects of antioxygenation, anti-inflammation, and anti-apoptosis. Among quantities of diseases related with H 2 therapy, the brain disease is a hotspot as brain tissue and cell damage are easier to be induced by oxidative stress and other stimulations. In this review, emphasis is on stroke, traumatic brain injuries, and degenerative diseases, such as Alzheimer′s disease and Parkinson′s disease. Taking into account the blood-brain barrier, penetrability, possible side effects, and the molecular properties of H 2 within a single comprehensive review should contribute to advancing both clinical and non-clinical research and therapies. A systematic introduction of H 2 therapy with regards to mechanisms and cerebral diseases both in animal and human subjects can make it easier to comprehend H 2 therapy and therefore provide the basis for further clinical strategy.

    Electrical impedance tomography (EIT) could be used as a portable non-invasive means to image the development of ischaemic stroke or haemorrhage. The purpose of this study was to examine if this was possible using time difference imaging, in the anesthetised rat using 40 spring-loaded scalp electrodes with applied constant currents of 50-150 μA at 2 kHz. Impedance changes in the largest 10% of electrode combinations were  -12.8%  ±  12.0% over the first 10 min for haemorrhage and  +46.1%  ±  37.2% over one hour for ischaemic stroke (mean  ±  SD, n  =  7 in each group). The volume of the pathologies, assessed by tissue section and histology post-mortem, was 12.6 μl  ±  17.6 μl and 12.6 μl  ±  17.6 μl for haemorrhage and ischaemia respectively. In time difference EIT images, there was a correspondence with the pathology in 3/7 cases of haemorrhage and none of the ischaemic strokes. Although the net impedance changes were physiologically reasonable and consistent with expectations from the literature, it was disappointing that it was not possible to obtain reliable EIT images. The reason for this are not clear, but probably include confounding effects of secondary ischaemia for haemorrhage and tissue and cerebrospinal fluid shifts for the stroke model. With this method, it does not appear that EIT with scalp electrodes is yet ready for clinical use. PMID:27200510

    Leptospirosis, a disease of protean manifestations occurs sporadically throughout the year with a peak seasonal incidence during the rainy season mimicking other febrile viral illness. In the rare case, the disease leads to renal and hepatic involvement with hemorrhage which may be associated with multisystem organ dysfunction in form of pulmonary, cardiac and central nervous system, when it is known as Weil’s disease. Rarely haemorrhagic manifestations are assosciated. Early diagnosis is important as sometimes the disease may be life threatening. Proper antibiotics results in dramatic improvement. We hereby presented a case that had clinical features of Weil’s disease with cough, dyspnoea and haemoptysis. Leptospirosis was detected on ELISA testing. Patient was cured rapidly with antibiotics.

    Full Text Available Postpartum hemorrhage (PPH represents a serious problem for women and obstetricians. Because of its association with haemorrhagic shock and predisposition to disseminated coagulopathy, it is a leading cause of maternal deaths worldwide. Furthermore, the jeopardy of PPH is rising with the secondary form of PPH occurring between 24 hours and 6 weeks postpartum, when women are already discharged home. The causes of this pathology are severe inflammation (endometritis inherited coagulation disorders, consumptive coagulopathy, and retained products of conceptions. Others are of rare occurrence, such as vessel subinvolution (VSI of the placental implantation site, uterine artery pseudo aneurysm, or trauma.

    Viral haemorrhagic septicaemia (VHS) is an economically very important fish disease in the northern hemisphere. When the VHS virus was first isolated in Denmark 50 yr ago, more than 80% of the 800 Danish fish farms were considered to be infected, but vigilant surveillance and eradication programmes...... led to a drastic reduction in prevalence, and finally, to complete eradication of VHS. Denmark thus obtained official status as an approved VHS-free member state within the European Union in November 2013. Data on outbreaks within the country have been collected since 1970, and here we combined...... such a cluster was a significant risk factor for VHS. For freshwater rainbow trout farms situated inland, the number of upstream farms was a determining risk factor for VHS, as was distance to the nearest VHS-infected farm and year.

    Full Text Available Hereditary Haemorrhagic Telangiectasia (Osler-Rendu-Weber disease is a rare autosomal dominant disorder commonly a ecting small vessels of skin and mucosa. It is usually misdiagnosed because of its atypical presentation. This disease frequently presents as epistaxis, GI bleed and visceral arterio venous malformations. Patient may present with stroke or migraine but presentation due to predominant respiratory symptoms may occur in the presence of pulmonary A-V stula. We present a 9 yr old male with dyspnoea on exertion and cyanosis and clubbing. He had a past history of intracerebral bleed with thrombocytopenia and he was being treated as ITP. Contrast echo revealed ndings suggestive of pulmonary arterio venous stula which led to subsequent investigations and retrospective evaluation and hence achieving the final diagnosis.

    Serological data on myxoma virus, rabbit haemorrhagic disease (RHD) virus and RHD-like viruses in juvenile rabbits (Oryctolagus cuniculus) trapped in 1995, 1996 and 1997 in two areas of France were analysed. For each disease, the effects of bodyweight, year, month and seropositivity for the other disease were modelled by using logistic regressions. In one area, a model including RHD seropositivity was selected to explain the myxoma virus seropositivity. Models including myxoma virus seropositivity were selected to explain the RHD seropositivity in both areas, and the odds of a rabbit being seropositive to both viruses were 5.1 and 8.4 times higher than the odds of a rabbit being seronegative to myxoma virus and seropositive to RHD. The year and bodyweight had significant effects for myxomatosis in one area and for RHD in both areas. PMID:15573951

    International Nuclear Information System (INIS)

    Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD). Research using different ligands to specific receptor sites will also be reviewed in pediatrics

    Cerebral cartography and connectomics pursue similar goals in attempting to create maps that can inform our understanding of the structural and functional organization of the cortex. Connectome maps explicitly aim at representing the brain as a complex network, a collection of nodes and their interconnecting edges. This article reflects on some of the challenges that currently arise in the intersection of cerebral cartography and connectomics. Principal challenges concern the temporal dynamics of functional brain connectivity, the definition of areal parcellations and their hierarchical organization into large-scale networks, the extension of whole-brain connectivity to cellular-scale networks, and the mapping of structure/function relations in empirical recordings and computational models. Successfully addressing these challenges will require extensions of methods and tools from network science to the mapping and analysis of human brain connectivity data. The emerging view that the brain is more than a collection of areas, but is fundamentally operating as a complex networked system, will continue to drive the creation of ever more detailed and multi-modal network maps as tools for on-going exploration and discovery in human connectomics.

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Dabigatran is an oral direct thrombin inhibitor (DTI) licensed for stroke prevention in atrial fibrillation and likely to be soon approved in Europe for treatment of venous thrombosis. Predictable pharmacokinetics and a reduced risk of intracranial haemorrhage do not negate the potential risk of haemorrhage. Unlike warfarin, there is no reversal agent and measurement of the anticoagulant effect is not 'routine'. The prothrombin time/international normalised ratio response to dabigatran is inconsistent and should not be measured when assessing a patient who is bleeding or needs emergency surgery. The activated partial thromboplastin time (APTT) provides a qualitative measurement of the anticoagulant effect of dabigatran. Knowledge of the time of last dose is important for interpretation of the APTT. Commercially available DTI assays provide a quantitative measurement of active dabigatran concentration in the plasma. If a patient receiving dabigatran presents with bleeding: omit/delay next dose of dabigatran; measure APTT and thrombin time (consider DTI assay if available); administer activated charcoal, with sorbitol, if within 2 h of dabigatran ingestion; give tranexamic acid (1 g intravenously if significant bleeding); maintain renal perfusion and urine output to aid dabigatran excretion. Dabigatran exhibits low protein binding and may be removed by dialysis. Supportive care should form the mainstay of treatment. If bleeding is life/limb threatening, consider an additional haemostatic agent. There is currently no evidence to support the choice of one haemostatic agent (FEIBA, recombinant factor VIIa, prothrombin complex concentrates) over another. Choice will depend on access to and experience with available haemostatic agent(s). PMID:23435652

    The purpose of this study was to evaluate the potential of high quality computed tomographic angiography (CTA) to replace digital subtraction angiography (DSA) in cases of ruptured saccular aneurysms and perform early surgical clipping or coiling on the basis of CTA alone. In a prospective study, 100 patients with aneurysmal subarachnoid haemorrhage (SAH) diagnosed by computed tomography underwent CTA. CTA revealed a total of 118 aneurysms including all ruptured aneurysms. A decision of direct surgical clipping, endovascular coiling or therapeutic abstention was made in 89 cases (89%) on the basis of CTA alone. Sixty-one direct surgical procedures were performed after CTA. Twenty-six cases underwent DSA for immediate endovascular treatment of the ruptured aneurysm. In 11 cases (11%), a DSA was performed prior to the therapeutic decision because of unclear aneurysm. Four cases were not treated because of initial poor clinical grade. The surgical findings were compared with CTA data and were considered accurate in all but one case. All patients underwent postoperative DSA within 10 days after SAH. The sensitivity and the specificity of CTA for the detection of all aneurysms, as compared with postoperative DSA, were 95.1 and 100%, respectively. A total of six unruptured aneurysms were missed initially, but were visible retrospectively on CTA in all but one case and were found in patients with multiple aneurysms in whom the ruptured aneurysm was detected by CTA. Current quality CTA allows reliable pretreatment planning for the majority of cases of aneurysmal subarachnoid haemorrhage and diminishes the pretreatment evaluation time critically. Complementary pretreatment DSA is required in situations where CTA characteristics of the ruptured aneurysm is unsatisfactory. PMID:12779201

    Full Text Available Hereditary Haemorrhagic Telangiectasia (HHT is a genetic disorder characterised by a multi-systemic vascular dysplasia and haemorrhage. The precise factors leading to these vascular malformations are not yet understood and robust animal models of HHT are essential to gain a detailed understanding of the molecular and cellular events that lead to clinical symptoms, as well as to test new therapeutic modalities. Most cases of HHT are caused by mutations in either endoglin (ENG or activin receptor like kinase 1 (ACVRL1, also known as ALK1. Both genes are associated with TGFβ/BMP signalling, and loss of function mutations in the co-receptor ENG are causal in HHT1, whilst HHT2 is associated with mutations in the signalling receptor ACVRL1. Significant advances in mouse genetics have provided powerful ways to study the function of Eng and Acvrl1 in vivo, and to generate mouse models of HHT disease. Mice that are null for either Acvrl1 or Eng genes show embryonic lethality due to major defects in angiogenesis. However mice that are heterozygous for mutations in either of these genes develop to adulthood with no effect on survival. Although these heterozygous mice exhibit selected vascular phenotypes relevant to the clinical pathology of HHT, the phenotypes are variable and generally quite mild. An alternative approach using conditional knockout mice allows us to study the effects of specific inactivation of either Eng or Acvrl1 at different times in development and in different cell types. These conditional knockout mice provide robust and reproducible models of arteriovenous malformations, and they are currently being used to unravel the causal factors in HHT pathologies. In this review, we will summarize the strengths and limitations of current mouse models of HHT, discuss how knowledge obtained from these studies has already informed clinical care and explore the potential of these models for developing improved treatments for HHT patients in the

    bicarbonate (Bicarb, 1 m; 350–500 ml) or an equal volume of normal saline (Sal) was infused intravenously at a constant rate during a ‘2000 m' maximal ergometer row in six male oarsmen (23 ± 2 years; mean ± s.d.). During the Sal trial, pH decreased from 7.41 ± 0.01 at rest to 7.02 ± 0.02 but only to 7.36 ± 0.......05) following the Sal and Bicarb trials, respectively. Accordingly, the cerebral metabolic ratio decreased equally during the Sal and Bicarb trials: from 5.8 ± 0.6 at rest to 1.7 ± 0.1 and 1.8 ± 0.2, respectively. The enlarged blood-buffering capacity after infusion of Bicarb eliminated metabolic acidosis......Exercise lowers the cerebral metabolic ratio of O2 to carbohydrate (glucose + 1/2 lactate) and metabolic acidosis appears to promote cerebral lactate uptake. However, the influence of pH on cerebral lactate uptake and, in turn, on the cerebral metabolic ratio during exercise is not known. Sodium...

    2014-01-01

    Background Cerebral oedema occurs with cerebral malaria, and some clinicians think osmotic diuretics, such as mannitol or urea, may improve outcomes. Objectives To compare mannitol or urea to placebo or no diuretic for treating children or adults with cerebral malaria. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register (Issue 4, 2010), CENTRAL (The Cochrane Library Issue 12, 2010), MEDLINE (1966 to November 2010), EMBASE (1974 to November 2010), LILACS (1982 to November 2010), and the reference lists of articles. We contacted relevant organizations and researchers. Selection criteria Randomized or quasi-randomized controlled trials comparing mannitol or urea to placebo or no treatment in children and adults with cerebral malaria. Primary outcomes were death, life-threatenining sequelae and major neurological sequelae at six months. Data collection and analysis Two authors applied the inclusion criteria, assessed risk of bias, and extracted data independently. Main results One trial met the inclusion criteria, comparing mannitol 20% to saline placebo in 156 Ugandan children. Allocation was concealed. No difference in mortality, time to regain consciousness, or neurological sequelae were detected. Authors’ conclusions There are insufficient data to know what the effects of osmotic diuretics are in children with cerebral malaria. Larger, multicentre trials are needed. PMID:21491391

    The present study observed hemodynamic changes in 26 patients with cerebral arteriosclerosis using a cerebral circulation dynamics detector and transcranial Doppler.In patients with cerebral arteriosclerosis the blood supply and flow rate in the bilateral carotid arteries and the blood flow rate in the anterior cerebral and middle cerebral arteries were similar to normal controls, but the cerebral vascular resistance, critical pressure and pulsatility index were increased, and cerebral arterial elasticity and cerebral blood flow autoregulation were decreased.Compared with the lesioned hemisphere of patients with cerebral infarction, the total blood supply and blood flow rate of patients with cerebral arteriosclerosis were higher.Compared with normal subjects, patients with cerebral arteriosclerosis exhibited cognitive disturbances, mainly in short-term memory, attention, abstract capability, and spatial and executive dysfunction.Results showed that cerebral arteriosclerosis does not directly affect the blood supply of a cerebral hemisphere, but affects cognitive function.The increased cerebral vascular resistance and reduced autoregulation of cerebral blood vessels may be important hemodynamic mechanisms of arteriosclerosis-induced cerebral infarction.

    Full Text Available Abstract Background To investigate the effect of preceding acute exercise on the peripheral vascular response to a mental task, we measured splanchnic and cerebral blood flow responses to performing a mental task after exercise and resting. Methods In the exercise trial, 11 males exercised for 30 min on a cycle ergometer with a workload set at 70% of the age-predicted maximal heart rate for each individual. After a 15-min recovery period, the subjects rested for 5 min for pre-task baseline measurement and then performed mental arithmetic for 5 min followed by 5 min of post-task measurement. In the resting trial, they rested for 45 min and pre-task baseline data was obtained for 5 min. Then mental arithmetic was performed for 5 min followed by post-task measurement. We measured the mean blood velocity in the middle cerebral artery and superior mesenteric artery and the mean arterial pressure. Results Mean arterial pressure and mean blood velocity in the middle cerebral artery were significantly higher than the baseline during mental arithmetic in both exercise and resting trials. Mean blood velocity in the middle cerebral artery during mental arithmetic was greater in the control trial than the exercise trial. Mean blood velocity in the superior mesenteric artery showed no significant change during mental arithmetic from baseline in both trials. Conclusion These results suggest that acute exercise can moderate the increase in cerebral blood flow induced by a mental task.

    Full Text Available Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

    Acute management of patients with traumatic brain/blast injury is a challenge. To minimize secondary injury and improve outcome, it is critical to detect neurological deterioration early, when it is potentially reversible. One potential monitoring method is cerebral electrical impedance (rheoencephalography-REG) because of its non-invasiveness and good time resolution. Reported here are the results of cerebral blood flow (CBF) manipulations comparing electroencephalogram (EEG) with REG (both intra-cerebral) and measuring with surface and skull REG electrodes. Our hypothesis was that REG would reflect spreading depression and CBF autoregulation. Animal experiments were performed using one rat (four trials with intracerebral electrodes), monkeys (n=8, with surface electrodes) and pigs (n = 24 pigs with skull electrodes; 57 trials, 19 types of liposomes). Challenges included intracranial pressure (ICP) elevation, liposome infusion, and hemorrhage. Data were stored on a PC and evaluated off line. CBF autoregulation was evaluated both by visual inspection and by a Matlab script. These studies confirmed that REG reflects CBF autoregulation and that REG is useful for detecting spreading depression (SD), vasospasm and the lower limit of CBF autoregulation. These findings have clinical relevance for use in noninvasive neuro-monitoring in the neurosurgery intensive care and during transportation of patients with brain injury.

    1986-02-01

    Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

  19. Cerebral white matter hypoplasia

    International Nuclear Information System (INIS)

    This paper demonstrates the MR imaging findings in children with cerebral white matter hypoplasia (CWMH). The MR studies of four children, aged 3-7 y (mean age, 2.3 y) with a diagnosis of CWMH were reviewed. In all cases multiplanar T1-weighted and T2-weighted spin-echo images were obtained. All children had similar histories of severe developmental delay and nonprogressive neurologic deficits despite normal gestational and birth histories. In two cases there was a history of maternal cocaine abuse. Autopsy correlation was available in one child. The MR images of all four children demonstrated diffuse lack of white matter and enlarged ventricles but normal-appearing gray matter. The corpus callosum, although completely formed, was severely thinned. There was no evidence of gliosis or porencephaly, and the distribution of myelin deposition was normal for age in all cases. Autopsy finding in one child correlated exactly with the MR finding
