    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.

    Magnetic induction tomography (MIT) is a new electromagnetic imaging modality which has the potential to image changes in the electrical conductivity of the brain due to different pathologies. In this study the feasibility of detecting haemorrhagic cerebral stroke with a 16-channel MIT system operating at 10 MHz was investigated. The finite-element method combined with a realistic, multi-layer, head model comprising 12 different tissues, was used for the simulations in the commercial FE package, Comsol Multiphysics. The eddy-current problem was solved and the MIT signals computed for strokes of different volumes occurring at different locations in the brain. The results revealed that a large, peripheral stroke (volume 49 cm(3)) produced phase changes that would be detectable with our currently achievable instrumentation phase noise level (17 m degrees ) in 70 (27%) of the 256 exciter/sensor channel combinations. However, reconstructed images showed that a lower noise level than this, of 1 m degrees , was necessary to obtain good visualization of the strokes. The simulated MIT measurements were compared with those from an independent transmission-line-matrix model in order to give confidence in the results.

    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. Secondary outcomes include: Mortality, Rankin, Barthel, EuroQol, and Survival. Trial

  13. Frequency-difference MIT imaging of cerebral haemorrhage with a hemispherical coil array: numerical modelling.

    Science.gov (United States)

    Zolgharni, M; Griffiths, H; Ledger, P D

    2010-08-01

    The feasibility of detecting a cerebral haemorrhage with a hemispherical MIT coil array consisting of 56 exciter/sensor coils of 10 mm radius and operating at 1 and 10 MHz was investigated. A finite difference method combined with an anatomically realistic head model comprising 12 tissue types was used to simulate the strokes. Frequency-difference images were reconstructed from the modelled data with different levels of the added phase noise and two types of a priori boundary errors: a displacement of the head and a size scaling error. The results revealed that a noise level of 3 m degrees (standard deviation) was adequate for obtaining good visualization of a peripheral stroke (volume approximately 49 ml). The simulations further showed that the displacement error had to be within 3-4 mm and the scaling error within 3-4% so as not to cause unacceptably large artefacts on the images.

    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.

  1. The FIB-PPH trial: fibrinogen concentrate as initial treatment for postpartum haemorrhage: study protocol for a randomised controlled trial

    Directory of Open Access Journals (Sweden)

    Wikkelsoe Anne

    2012-07-01

    Full Text Available Abstract Background Postpartum haemorrhage (PPH remains a leading cause of maternal mortality worldwide. In Denmark 2% of parturients receive blood transfusion. During the course of bleeding fibrinogen (coagulation factor I may be depleted and fall to critically low levels, impairing haemostasis and thus worsening the ongoing bleeding. A plasma level of fibrinogen below 2 g/L in the early phase of postpartum haemorrhage is associated with subsequent development of severe haemorrhage. Use of fibrinogen concentrate allows high-dose substitution without the need for blood type crossmatch. So far no publications of randomised controlled trials involving acutely bleeding patients in the obstetrical setting have been published. This trial aims to investigate if early treatment with fibrinogen concentrate reduces the need for blood transfusion in women suffering severe PPH. Methods/Design In this randomised placebo-controlled double-blind multicentre trial, parturients with primary PPH are eligible following vaginal delivery in case of: manual removal of placenta (blood loss ≥ 500 ml or manual exploration of the uterus after the birth of placenta (blood loss ≥ 1000 ml. Caesarean sections are also eligible in case of perioperative blood loss ≥ 1000 ml. The exclusion criteria are known inherited haemostatic deficiencies, prepartum treatment with antithrombotics, pre-pregnancy weight Primary outcome is the need for blood transfusion. To investigate a 33% reduction in the need for blood transfusion, a total of 245 patients will be included. Four university-affiliated public tertiary care hospitals will include patients during a two-year period. Adverse events including thrombosis are assessed in accordance with International Conference on Harmonisation (ICH good clinical practice (GCP.

    Pregnancy is a state of hypercoagulobility that might be an evolutionary way of protecting parturients from exsanguination following child birth. Observational studies suggest an association between a low level of fibrinogen (coagulation factor I) at the start of postpartum haemorrhage (PPH) and subsequent severity of bleeding. Fibrinogen concentrate may be prescribed to correct acquired hypofibrinogenaemia, but evidence is lacking regarding the treatment efficacy. This thesis assesses the current evidence for the use of fibrinogen concentrate and haemostatic assessment in bleeding patients with special attention to the obstetrical population. It includes five papers: In Paper I the benefits or harms of fibrinogen concentrate in bleeding patients in general was evaluated using a systematic Cochrane review methodology with metaanalysis of all published randomized controlled trials (RCTs). Six trials with high risk of bias were included (248 patients). Fibrinogen appeared to reduce the need of allogenic transfusions by 53%. However, the included trials were conducted only in an elective surgical setting with a population of mainly cardiac surgical patients. Paper II was also a systematic review based on Cochrane methodology evaluating the use of viscoelastic haemostatic assays to guide haemostatic transfusion in bleeding patients. Nine RCTs (776 patients) with high risk of bias were included primarily in elective cardiac surgical patients and none were specific for the obstetric subpopulation. Viscoelastic haemostatic assay guided transfusion algorithm reduced blood loss and the proportion of patients exposed to fresh frozen plasma (FFP) or platelets. In both studies, we were unable to make firm conclusion on our primary outcome, "all cause mortality" due to lack of adequate data. Paper III was based on two national Danish registries evaluating the predictability of postpartum blood transfusion. Prediction was found difficult. However, retained placental parts seemed

    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.

    Exact quantification of vasospasm by angiography is known to be difficult especially in small vessels. The purpose of the study was to develop a new method for computerized analysis of small arteries and to demonstrate feasibility on cerebral angiographies of rats acquired on a clinical angiography unit. A new software tool analysing grey values and subtracting background noise was validated on a vessel model. It was tested in practice in animals with subarachnoid haemorrhage (SAH). A total of 28 rats were divided into four groups: SAH untreated, SAH treated with local calcium antagonist, SAH treated with placebo, and sham-operated. The diameters of segments of the internal carotid, caudal cerebral, middle cerebral, rostral cerebral and the stapedial arteries were measured and compared to direct measurements of the diameters on magnified images. There was a direct correlation between the cross-sectional area of vessels measured in a phantom and the measurements acquired using the new image analysis method. The spread of repeated measurements with the new software was small compared to the spread of direct measurements of vessel diameters on magnified images. Application of the measurement tool to experimental SAH in rats showed a statistically significant reduction of vasospasm in the SAH groups treated with nimodipine-releasing pellets in comparison to all the other groups combined. The presented computerized method for analysis of small intracranial vessels is a new method allowing precise relative measurements. Nimodipine-releasing subarachnoidal pellets reduce vasospasm, but further testing with larger numbers is necessary. The tool can be applied to human angiography without modification and offers the promise of substantial progress in the diagnosis of vasospasm after SAH. (orig.)

    Background The mechanism of cerebral vasospasm following subarachnoid haemorrhage(SAH)is not understood.Here,we hypothesized that apoptosis of endothelial cells induced by p53 and its target gene em dash p53 upregulated modulator of apoptosis(PUMA)played an important role in development of cerebral vasospasm.We also observed the effects of a p53 inhibitor,pifithrin-α(PFT-α),on reducing the expression of p53 and PUMA,consequently decreasing the apoptosis of endothelial cells and alleviating cerebral vasospasm.Methods Male Sprague-Dawley rats weighing 300-350 g were randomly divided into five groups:a control group (sham surgery),a SAH group,a SAH+dimethyl sulfoxide(DMSO)group,a SAH+PFT-α(0.2 mg/kg)group and a SAH+PFr-α(2.0 mg/kg)group.PFT-α was injected intraperitoneally immediately after SAH.Rats were sacrificed 24hours after SAH.Western blot and immunohistochemical staining were used to detect the levels of p53,PUMA and caspase-3 protein.In addition,mortality and neurological scores were assessed for each group.Statistical significance was assured by analysis of variance performed in one way ANOVA followed by the Tukey test.The neurological and mortality scores were analyzed by Dunn's method and Fisher exact test,respectively.Results After SAH,Western blot and immunohistochemical staining showed the levels of p53,PUMA and caspase-3 in the endothelial cells and the numbers of TdT mediated dUTP nick end labelling(TUNEL)positive endothelial cells were all significantly increased in the basilar arteries (P<0.05),but significantly reduced by PFT-α(P<0.05).These changes were accompanied by increasing diameters and declining wall thickness of basilar arteries(P<0.05),as well as reduced mortality and neurological deficits of the rats(P<0.05).Conclusions PFT-α could protect cerebral vessels from development of vasospasm and improve neurological outcome as well as reduce the mortality via suppressing apoptosis induced by p53 in the endothelial cells of

    Severe haemophilia A was diagnosed postpartum in a newborn. The mother was known as a conductor (intron 22 inversion) and an uncle had a persistently high titer inhibitor after failed ITI. Due to a cephalhaematoma, a high-dose pdFVIII substitution was given within the first days after birth. At the age of six month a severe cerebral haemorrhage occurred, making a high-dose pdFVIII substitution and neurosurgical intervention necessary. Several days later a porth-a-cath-system was implanted. The development of a high titer inhibitor occured six days later, an ITI was started according to the Bonn Protocol. Initially rFVIIa was given in addition to the pdFVIII substitution. Seven days after the beginning of treatment the inhibitor was no longer detectable. At monthly intervals the FVIII dosage was reduced until the dosage complied with a prophylaxis in severe haemophilia A. The duration of the ITI was nine months. A total of 30 mg rFVIIa and 276000 IU pdFVIII were used; costs in total: 280173.60 Euro.

    Background The randomized clinical trial, SafeBoosC II, examined the effect of monitoring of cerebral oxygenation by near-infrared spectroscopy combined with a guideline on treatment when cerebral oxygenation was out of the target range. Data on cerebral oxygenation was collected in both the intervention and the control group. The primary outcome was the reduction in the burden of cerebral hypo- and hyperoxia between the two groups. In this study we describe the associations between the burden of cerebral hypo- and hyperoxia, regardless of allocation to intervention or control group, and the biomarkers of brain injury from birth till term equivalent age that was collected as secondary and explorative outcomes in the SafeBoosC II trial. Methods Cerebral oxygenation was continuously monitored during the first 72h of life in 166 extremely preterm infants. Cranial ultrasound was performed at day 1,4,7,14, and 35 and at term. Electroencephalogram (EEG) was recorded at 64h. Blood-samples taken at 6 and 64 hours were analysed for the brain injury biomarkers; S100beta, brain-fatty-acid-binding-protein, and neuroketal. All analyses were conducted post hoc. Results Significantly more infants with a cerebral burden of hypoxia within the 4th quartile versus infants within quartile 1–3 were diagnosed with severe intracranial haemorrhage (11/39 versus 11/117, p = 0.003), had low burst rate on EEG (12/28 versus 21/103, p = 0.015), or died (14/41 versus 18/123, p = 0.006), whereas none of these events were significantly associated with cerebral hyperoxia. The blood biomarkers were not significantly associated with the burden of cerebral hypo- or hyperoxia. Conclusions The explorative analysis showed that early burden of cerebral hypoxia, but not hyperoxia was significantly associated with low brain electrical activity and severe intracranial haemorrhage while none of the three blood biomarkers were associated with the burden of either cerebral hypo- or hyperoxia.

    2016-01-01

    Full Text Available We report on two cases of transient akinetic mutism after massive subarachnoid haemorrhage due to the rupture of an intracranial aneurysm of the anterior cerebral artery (ACA. In the two cases, vasospasm could not be demonstrated by imaging studies throughout the clinical course. Both patients shared common radiological features: a hydrocephalus due to haemorrhagic contamination of the ventricular system and a mass effect of a subpial hematoma on the borders of the corpus callosum. Patients were also investigated using auditory event-related evoked potentials at acute stage. In contrast to previous observations of akinetic mutism, P300 wave could not be recorded. Both patients had good recovery and we hypothesized that this unexpectedly favourable outcome was due to the absence of permanent structural damage to the ACA territory, with only transient dysfunction due to a reversible mass effect on cingulate gyri.

    Background: Postpartum haemorrhage (PPH) is a leading cause of maternal death. Tranexamic acid has the potential to reduce bleeding and a large randomized controlled trial of its effect on maternal health outcomes in women with PPH (The WOMAN trial) is ongoing. We will examine the effect of tranexamic acid on fibrinolysis and coagulation in a subset of WOMAN trial participants. Methods. Adult women with clinically diagnosed primary PPH after vaginal or caesarean delivery are eligible for inclusion in the WOMAN trial. In a sub-group of trial participants, blood samples will be collected at baseline and 30 minutes after the first dose of tranexamic acid or matching placebo.  Our primary objective is to evaluate the effect of tranexamic acid on fibrinolysis. Fibrinolysis will be assessed by measuring D-dimers and by rotational thromboelastometry (ROTEM). Secondary outcomes are international normalized ratio (INR), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, haemoglobin and platelets. We aim to include about 180 women from the University College Hospital, Ibadan in Nigeria. Discussion:  This sub-study of WOMAN trial participants should provide information on the mechanism of action of tranexamic acid in women with postpartum haemorrhage. We present the trial protocol and statistical analysis plan. The trial protocol was registered prior to the start of patient recruitment. The statistical analysis plan was completed before un-blinding. Trial registration: The trial was registered: ClinicalTrials.gov, Identifier NCT00872469 https://clinicaltrials.gov/ct2/show/NCT00872469; ISRCTN registry, Identifier ISRCTN76912190 http://www.isrctn.com/ISRCTN76912190 (Registration date: 22/03/2012).

    1996-02-01

    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.

    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.

    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.)

It is proven that improvement of gross motor function could reduce CP-related disabilities and provide better quality of life in this group of patients. Therefore, the aim of this trial is to evaluate the effectiveness of cerebrolysin (CBL) on gross motor function of children with CP who are undergoing treatment. In this clinical trial study, paediatric patients aged 18-75 months with spastic diplegic or quadriplegic cerebral palsy, who were under rehabilitation therapy, were selected and randomly allocated in control and CBL groups. Patients in CBL group underwent treatment with standard rehabilitation therapy plus CBL. The latter was administrated intramuscularly as a single daily dose of 0.1 cc/kg for 10 days and then continued weekly for 4 months. Gross motor function of participants in the two studied groups, before and after trial, was evaluated and compared using the validated Persian version of gross motor function classification system-expanded and revised (GMFCS-E&R). During this trial, 108 patients with CP were evaluated for eligibility. From these, 50 patients were enrolled and randomly allocated in the CBL and control groups. Four months after trial, the mean level of GMFCS decreased significantly in the two groups (P < 0.05). However, it was significantly lower in the CBL group than in the control group (2.1 vs. 3.16, P < 0.05). The results of this trial indicated that CBL could improve gross motor function in patients with CP. This finding is consistent with neurotrophic and neuroprotective effects of CBL, which have been reported in various clinical trials in other neurological disorders. Further studies are recommended to establish the value of continued neuroprotection and to determine the pharmacokinetics/dynamics of CBL in this group of patients.

    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.

    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.

    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.

    OBJECTIVE To assess the effect and cafety of t iclopidine in the prevention of ischemic cerebral stroke and to compare theeffect of low-dose aspirin with t iclopidine. BACKGROUND The effect and safety of ticlopidine irn the prevention of ischemic cerebral stroke in China has not been reported. 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.

    Full Text Available BACKGROUND: Treadmill gait training as a therapeutic resource in the rehabilitation of children with cerebral palsy has recently been the focus of many studies; however, little is still known regarding its effect on static and functional balance in children. OBJECTIVE: The aim of the present study was to compare the effects of treadmill training and over ground gait training in children with cerebral palsy. METHOD: A randomized controlled trial with blinded evaluator was conducted with children with cerebral palsy between three and 12 years of age categorized in Levels I to III of the Gross Motor Function Classification System. Assessments were performed before and after the intervention and involved the Berg balance scale as well as the determination of oscillations from the center of pressure in the anteroposterior and mediolateral directions with eyes open and closed. The experimental group was submitted to treadmill training and the control group performed gait training over the ground. The intervention consisted of two 30-minute sessions per week for seven weeks. RESULTS: Both groups exhibited better functional balance after the protocol. The experimental group had higher Berg balance scale scores and exhibited lesser mediolateral oscillation with eyes open in comparison to the control group. CONCLUSIONS: Treadmill training had a greater effect on functional balance and mediolateral oscillation in comparison to over ground gait training in children with cerebral palsy.

    Full Text Available Clinical evaluation of patients with stroke, immediately followed by a neuroradiological exam (generally CT scan is essential for the diagnosis of haemorragic stroke. First-line diagnostic work-up at Emergency Department should be performed as soon as possible after stroke onset in order to limit the consequences of the disease. In particular, cases with clotting abnormalities and/or needing surgical evaluation must be rapidly assessed and treated. Patients without indication to neurosurgery in the emergency setting show a better long-term prognosis (reduced disability/mortality if admitted to dedicated ward (“Stroke Unit” rather than general ward. In the acute phase of the disease, blood pressure monitoring appears essential to prevent haematoma growth, which represents a predictor of poor outcome. Nowadays, an on-going international randomized clinical trial (INTERACT 2 is testing if an aggressive reduction of blood pressure (beyond the thresholds suggested by current guidelines may improve prognosis. Moreover, clinical and instrumental prevention, assessment and treatment of potential complications (such as hyperglicemia, cerebral oedema, seizure, deep venous thrombosis stand for additional prognostic key-issues. On top of that, further neuroradiological evaluation (with CT, CTA, MRI/MRA and/or endovascular tecniques in properly selected patients is helpful for the diagnosis and eventually the treatment of the underlying cause of haemorrhage. Finally, advanced neuroimaging, in addition to laboratory exams, could improve the management of patients who has haemorrhagic stroke while taking oral anticoagulants.

    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 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

    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 Background: Some cases of subarachnoid haemorrhage (SAH have been associated with vigorous physical activity, including sports. Our research aimed to describe the association between SAH and sports and to identify the types of sports that were more frequently found as precipitating factors in a tertiary single-centre SAH register. Methods: We retrieved information from a prospectively collected SAH registry and reviewed discharge notes of acute SAH patients admitted to the Stroke Unit of Hospital de Santa Maria, Lisbon, between 1995 and 2014. Results: Out of 738 patients included in the analysis, 424 (57.5% cases of SAH were preceded by physical activity. Nine cases (1.2% were associated with sports, namely running (2 cases, aerobics (2 cases, cycling, body balance, dance, surf and windsurf. Patients with SAH while practicing sports were younger than controls (average age 43.1 vs. 57.0 years; p = 0.007. In 1 patient, there was a report of trauma to the neck. Patients in the sports group only had Hunt and Hess scale grades 1 (11.1% or 2 (88.9% at admission, while patients in the control group had a wider distribution in severity. Conclusions: Our findings indicate that SAH precipitated by sports is not very frequent and is uncommonly related to trauma. Patients who suffered SAH associated with sports were younger and apparently had a milder clinical presentation.

    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.

  8. Splint: the efficacy of orthotic management in rest to prevent equinus in children with cerebral palsy, a randomised controlled trial

    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

  9. Takotsubo cardiomyopathy following subarachnoid haemorrhage.

    2014-08-01

    A 67-year-old woman was admitted with aneurysmal subarachnoid haemorrhage and a 12-lead ECG showed ST segment elevation. Transthoracic echocardiography confirmed akinesis of the left ventricular mid-apical segment, with an ejection fraction of 26%, features characteristic of takotsubo cardiomyopathy. Five days later, we identified thrombus in the apex of the left ventricle. Sixteen days after onset, the thrombus had disappeared and wall motion improved (ejection fraction 58%) without evidence of cardioembolism. Takotsubo cardiomyopathy is a cause of cardiac dysfunction after stroke, including SAH. It is characterised by transiently depressed contractile function of the left mid and apical ventricle, without obstructive coronary artery disease. Clinicians should suspect takotsubo cardiomyopathy in patients with subarachnoid haemorrhage who have an ECG abnormality. Echocardiography is needed to detect the distinctive regional wall motion abnormality. Despite its severity in the acute phase, takotsubo cardiomyopathy is self-limiting and its management is conservative.

    As the motor system relies heavily on deep sensory stimulation, recent studies have investigated the effect of vibration stimuli. Although research suggests a positive influence of vibration on motor performance in individuals with neurological disorders, there are very limited numbers of studies in children with cerebral palsy (CP). The objective of the present study was to evaluate the effects of sound wave vibration therapy on spasticity and motor function in children with CP. In this 3-month trial, 89 children with spastic CP were randomized to either continue their physiotherapy treatment (PT) or to receive vibration therapy twice a week in addition to their PT program. The randomization was stratified according to the Gross Motor Function Classification System (GMFCS) level to ensure similar functional ability. Children were assessed at baseline and after the 12-week intervention period. The outcomes measured were spasticity level as assessed by Modified Modified Ashworth Scale (MMAS) and gross motor function as assessed by Gross Motor Function Measurement (GMFM-88). Subgroup analysis was performed for the GMFCS. Significant differences between groups were detected for changes in spasticity level and gross motor function after the three months intervention. In conclusion, vibration therapy may decrease spasticity and improve motor performance in children with CP. The results of the present trial serve as valuable input for evidence-based treatments in paediatric neurorehabilitation.

    Extracorporeal membrane oxygenation (ECMO) was first used in adults with severe respiratory failure in the 1970s. Its use has been steadily increasing since the 1990s after a trial demonstrated improved survival. There are currently seven centres in the UK offering ECMO to adults. Neurological complications are often picked up within the first few days of initiating ECMO. Intracerebral haemorrhage is a well recognised complication and it is the leading cause of death in infants on ECMO and rates of 9-18.9% in adults have been reported. We report a 52-year-old woman admitted in severe type 1 respiratory failure in January 2012. She was transferred to a tertiary centre and suffered bitemporal and right parietal haemorrhages on ECMO in late February. She was repatriated to our unit for rehabilitation in April 2012. Her rehabilitation needs represent the complexity of this patient group with multiple medical, behavioural and physical challenges.

    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

    Full Text Available BACKGROUND: Intracranial haemorrhage represents the most feared stroke subtype. AIM: To evaluate the burden of intracranial haemorrhage in Tuscany hospitals with special reference to Livorno district. MATERIALS AND METHODS: Data of patients discharged in 2009 from Tuscan and Livorno hospitals with codes ICD-9-CM related to any type of spontaneous intracranial haemorrhage were selected and analyzed. RESULTS: 3,472 patients were discharged from Tuscan hospitals with these diagnoses. Overall mortality was 24.3%. 50% of patients were admitted in Internal Medicine wards. Incidence of intracranial haemorrhage and intracerebral haemorrhage (ICH in population of Livorno district was 64 and 45/100,000 inhabitants/year with related mortality of 36.5% and 39.4%respectively. Intra-hospital mortality of patients admitted in Livorno hospitals for intracranial haemorrhage were 36.7%. 40% of deaths occurred in the first 48 hours. 69.6% of intracranial haemorrhage were ICHs, 16.8% subaracnoideal. Intra-hospital mortality, admissions for intracranial haemorrhage in respect of total admissions and mortality for intracranial haemorrhage in respect to total mortality increased in the last decade. 23% of patients with intracranial haemorrhage and 16% of patients with ICH underwent to surgical procedures. ICHs related to antithrombotic treatment significantly increased in the last years. Mortality in patients on antithrombotic drugs was three times over compared to that in patients not undergone these drugs (43.7% vs 12.8%, p < 0.01. CONCLUSION: There is an increasing trend in frequency, mortality and hospital burden of intracranial haemorrhage and ICH. Efforts aimed at reducing the burden and consequences of this devasting disease are warranted.

    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 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.

    2016-01-01

    Chronic haemorrhagic radiation proctitis(CHRP) is a difficult problem faced by the patients following radiation for pelvic malignancy. There is no standardtreatment for this condition, but many methods of treatment are available. The aim of this study was to review the literature to see whether there is an improvement in the available evidence in comparison with previously published systematic reviews in treating patients with CHRP. The Pub Med/Medline database and Google Scholar search was selectively searched. Studies, which treated patients with rectal bleeding due to chronic radiation proctitis or CHRP, were included. Seventy studies were finally selected out of which 14 were randomized controlled clinical trials. Though these studies could not be compared, it could be seen that there was an improvement in the methodology of the studies. There was an objective assessment of symptoms, signs and an objective assessment of outcomes. But, still, there were only a few studies that looked into the quality of life following treatment of CHRP. To increase recruitment to trials, a national registry of cases with established late radiation toxicity would facilitate the further improvement of such studies. Some of the conclusions that could be reached based on the available evidence are 4% formalin should be the first line treatment for patients with CHRP. Formalin and argon plasma coagulation(APC) are equally effective, but formalin is better for severe disease. Refractory patients, not responding to formalin or APC, need to be referred for hyperbaric oxygen therapy or surgery. Radio-frequency ablation is a promising modality that needs to be studied further in randomized trials.

  3. Viral haemorrhagic fevers in healthcare settings.

    Ftika, L; Maltezou, H C

    2013-03-01

    Viral haemorrhagic fevers (VHFs) typically manifest as rapidly progressing acute febrile syndromes with profound haemorrhagic manifestations and very high fatality rates. VHFs that have the potential for human-to-human transmission and onset of large nosocomial outbreaks include Crimean-Congo haemorrhagic fever, Ebola haemorrhagic fever, Marburg haemorrhagic fever and Lassa fever. Nosocomial outbreaks of VHFs are increasingly reported nowadays, which likely reflects the dynamics of emergence of VHFs. Such outbreaks are associated with an enormous impact in terms of human lives and costs for the management of cases, contact tracing and containment. Surveillance, diagnostic capacity, infection control and the overall preparedness level for management of a hospital-based VHF event are very limited in most endemic countries. Diagnostic capacities for VHFs should increase in the field and become affordable. Availability of appropriate protective equipment and education of healthcare workers about safe clinical practices and infection control is the mainstay for the prevention of nosocomial spread of VHFs.

    2000-02-01

    The causes of non-haemorrhagic obstetric shock (pulmonary thromboembolism, amniotic fluid embolism, acute uterine inversion and sepsis) are uncommon but responsible for the majority of maternal deaths in the developed world. Clinically suspected pulmonary thromboembolism should be treated initially with heparin and objective testing should be performed. If the diagnosis is confirmed, heparin is usually continued until delivery, following which anticoagulation in the puerperium is achieved with either warfarin or heparin. Amniotic fluid embolism is a rare complication of pregnancy, occurring most commonly during labour. The management of amniotic fluid embolism involves maternal oxygenation, the maintenance of cardiac output and blood pressure, and the management of any associated coagulopathy. Acute uterine inversion arises most commonly following mismanagement of the third stage of labour. The shock in uterine inversion is neurogenic in origin, although there may also be profound haemorrhage. The management of this condition includes maternal resuscitation and replacement of the uterus either manually, surgically or by hydrostatic pressure. Genital tract sepsis remains a significant cause of maternal death, the most common predisposing factor being prolonged rupture of the fetal membranes. The management of septic shock in pregnancy includes resuscitation, identification of the source of infection and alteration of the systemic inflammatory response.

    Full Text Available Introduction. The secondary increase in the size of intracranial haematomas as a result of spontaneous haemorrhage or trauma is of particular relevance in the event of prior intake of platelet aggregation inhibitors. We describe the effect of desmopressin acetate as a means of temporarily stabilising the platelet function. Patients and Methods. The platelet function was analysed in 10 patients who had received single (N=4 or multiple (N=6 doses of acetylsalicylic acid and 3 patients (control group who had not taken acetylsalicylic acid. All subjects had suffered intracranial haemorrhage. Analysis was performed before, half an hour and three hours after administration of desmopressin acetate. Statistical analysis was performed by applying a level of significance of P≤0.05. Results. (1 Platelet function returned to normal 30 minutes after administration of desmopressin acetate. (2 The platelet function worsened again after three hours. (3 There were no complications related to electrolytes or fluid balance. Conclusion. Desmopressin acetate can stabilise the platelet function in neurosurgical patients who have received acetylsalicylic acid prior to surgery without causing transfusion-related side effects or a loss of time. The effect is, however, limited and influenced by the frequency of drug intake. Further controls are needed in neurosurgical patients.

    2015-01-01

    The haemostatic management of major obstetric haemorrhage remains challenging, and current published guidance relies heavily on experience from the non-pregnant population and expert opinion. In recent years, an interest in the implications of relative hypofibrinogenaemia, point-of-care monitoring of coagulation abnormalities, and the potential to give goal-directed therapy to correct coagulopathies, have created the possibility of significantly challenging and changing guidance. There is evidence that the haemostatic impairment in the pregnant population is different from trauma-induced bleeding, and the type and rate of onset of coagulopathies differ depending on the underlying cause. This review examines areas such as possible intervention points, describes evidence for over-transfusion of fresh frozen plasma in some situations and challenges conventional thinking on formulaic management. It also examines the rationale for other therapeutic options, including fibrinogen concentrate and tranexamic acid.

    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.

    Cerebral vasospasm is a common and serious complication of aneurysmal subarachnoid haemorrhage. Despite the improvements in treatment of aneurysmal subarachnoid haemorrhage (aSAH), cerebral vasospasm complicating aSAH has remained the main cause of morbidity and mortality. Subarachnoid haemorrhage (SAH)-induced vasospasm is a complex entity caused by vasculopathy, impaired autoregulation, and hypovolaemia, causing a regional reduction of cerebral brain perfusion which can then induce ischaemia. Cerebral vasospasm can present either asymptomatically detected only radiologically or symptomatically (delayed ischaemic neurologic deficit). The various diagnostic approaches include the use of transcranial doppler, digital subtraction angiography and multimodal computed tomography (CT) and magnetic resonance (MR) techniques. Although digital subtraction angiography is usually the gold standard for the diagnosis of cerebral vasospam, transcranial doppler is commonly the first-screening method for the detection of cerebral vasospam. The treatment of subarachnoid haemorrhage -induced vasospasm include the use of both medical and endovascular therapy. The aim of this review is to discuss the various current therapeutic options and future perspective measures for reducing cerebral vasospasm induced stroke after SAH.

    Ebolaviruses and Marburgviruses (family Filoviridae) are among the most virulent pathogens for humans and great apes causing severe haemorrhagic fever and death within a matter of days. This group of viruses is characterized by a linear, non-segmented, single-stranded RNA genome of negative polarity. The overall burden of filovirus infections is minimal and negligible compared to the devastation caused by malnutrition and other infectious diseases prevalent in Africa such as malaria, dengue or tuberculosis. In this paper, we review the knowledge gained on the eco/epidemiology, the pathogenesis and the disease control measures for Marburg and Ebola viruses developed over the last 15 years. The overall progress is promising given the little attention that these pathogen have achieved in the past; however, more is to come over the next decade given the more recent interest in these pathogens as potential public and animal health concerns. Licensing of therapeutic and prophylactic options may be achievable over the next 5-10 years.

    Full Text Available Severe pulmonary haemorrhage is a rare necropsy finding in dogs but the leptospiral pulmonary haemorrhagic syndrome (LPHS is a well recognized disease in humans. Here we report a pulmonary haemorrhagic syndrome in dogs that closely resembles the human disease. All 15 dogs had massive, pulmonary haemorrhage affecting all lung lobes while haemorrhage in other organs was minimal. Histologically, pulmonary lesions were characterized by acute, alveolar haemorrhage without identifiable vascular lesions. Seven dogs had mild alveolar wall necrosis with hyaline membranes and minimal intraalveolar fibrin. In addition, eight dogs had acute renal tubular necrosis. Six dogs had a clinical diagnosis of leptospirosis based on renal and hepatic failure, positive microscopic agglutination test (MAT and/or positive blood/urine Leptospira-specific PCR. Leptospira could not be cultured post mortem from the lungs or kidneys. However, Leptospira-specific PCR was positive in lung, liver or kidneys of three dogs. In summary, a novel pulmonary haemorrhagic syndrome was identified in dogs but the mechanism of the massive pulmonary erythrocyte extravasation remains elusive. The lack of a consistent post mortem identification of Leptospira spp. in dogs with pulmonary haemorrhage raise questions as to whether additional factors besides Leptospira may cause this as yet unrecognized entity in dogs.

    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 : 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 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.

It was found that 37.39% of the newborns had retinal haemorrhages. The incidence, type and severity of retinal haemorrhages were related to the extent of obstetric trauma during birth. They were least with caesarean section. (4.35%, more in babies with spontaneous vaginal delivery (20%, more higher in infants over 3.5 kgm birth weight (33.33% and maximum in vacuum extraction deliveries (68.75%. A good correlation was made between the site and duration of cup application, level and rate of increase of negative pressure, the presence and size of cephalhematoma and the incidence and severity of retinal haemorrhages A good choice of cases as well as good control of the technique of vacuum extraction will minimize the incidence and severity of retinal haemorrhages in the new born.

    2011-01-01

    Acute haemorrhage is a frequent problem in medicine. Patients with acute bleeding may present with signs of hypotension and reduced organ perfusion. The physician's reflex action is often to treat such patients with intravenous volume replenishment using colloid or cristalloid liquids. Intravenous volume replenishment has, however, a downside: it increases the tendency to bleed and therefore can increase blood loss. Previous clinical observations and experimental animal and human studies addressing volume replenishment in haemorrhagic shock have repeatedly shown that accepting hypotension favourably affects prognosis. However, relevant practice guidelines, such as for gastrointestinal bleeding, usually advise liberal intravenous volume replenishment if hypotension is present. In this article we advocate caution when considering intravenous blood volume adjustment in haemorrhage.

Despite well known that carotidbodies have an important role in cerebral circulation andblood pH regulation, their roles has not been investigatedin subarachnoid haemorrhage. We investigated whetherthere is neuroprotective effect of neuron density of carotidbodies on the brain in subarachnoid haemorrhage.Methods: Twenty hybrid rabbits were studied. Four ofthem were used as reference group (n=4 and the remainingwas obliged to subarachnoid haemorrhage by injectingautologous blood into their cisterna magna (n=16and sacrificed after one month. All carotid bodies andbrains examined histopathologically using by stereologicmethods. The relationship between the neuronal densityof carotid body and degenerated neuron density of thehippocampus were compared statistically.Results: Five rabbits with subarachnoid haemorrhagedead during the follow-up time (n=5. The average neuronaldensity of carotid body was 4500±500 cells/mm3and of hippocampus 170.000±17.000 cell/mm3 in normalrabbit family. The degenerated neuron density ofthe hippocampus was 20.000±3.000 cells/mm3 in rabbitswith have high neuron density of carotid body and was65.000±8.000 cells/mm3 in rabbits with low neuron densityof carotid body. The differences between the neuronaldensity of carotid body and the degenerated neuron numbersof the hippocampus were significant.Conclusion: The neuron density of carotid body mayplay an important role on the protection of brain in subarachnoidhaemorrhage.Key words: Subarachnoid haemorrhage, carotid body,hippocampus, neurodegeneration, cerebral ischemia

    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.

    [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.

Results: At 6 months, the results of the Mini-Mental State Examination (MMSE and the Trail Making Test (TMT-Part A showed an improvement versus baseline in the donepezil treatment group. All groups showed a significant increase in regional cerebral blood flow (rCBF, mainly in the frontal lobe. Significant rCBF reduction was observed in the temporal lobe and cingulate gyrus in all 3 groups. Conclusion: AchEI treatment prevents the progression of cognitive impairment and increases the relative rCBF in the frontal lobe.

    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. Discussion This paper presents the rationale, design and protocol for Pediatric Endurance and Limb Strengthening (PEDALS; a Phase I randomized controlled trial

    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

    Full Text Available Abstract Background The use of botulinum toxin A (BT-A for the treatment of lower limb spasticity is common in children with cerebral palsy (CP. Following the administration of BT-A, physical therapy plays a fundamental role in potentiating the functionality of the child. The balance deficit found in children with CP is mainly caused by muscle imbalance (spastic agonist and weak antagonist. Neuromuscular electrical stimulation (NMES is a promising therapeutic modality for muscle strengthening in this population. The aim of the present study is to describe a protocol for a study aimed at analyzing the effects of NMES on dorsiflexors combined with physical therapy on static and functional balance in children with CP submitted to BT- A. Methods/Design Protocol for a prospective, randomized, controlled trial with a blinded evaluator. Eligible participants will be children with cerebral palsy (Levels I, II and III of the Gross Motor Function Classification System between five and 12 years of age, with independent gait with or without a gait-assistance device. All participants will receive BT-A in the lower limbs (triceps surae. The children will then be randomly allocated for either treatment with motor physical therapy combined with NMES on the tibialis anterior or motor physical therapy alone. The participants will be evaluated on three occasions: 1 one week prior to the administration of BT-A; 2 one week after the administration of BT-A; and 3 four months after the administration of BT-A (end of intervention. Spasticity will be assessed by the Modified Ashworth Scale and Modified Tardieu Scale. Static balance will be assessed using the Medicapteurs Fusyo pressure platform and functional balance will be assessed using the Berg Balance Scale. Discussion The aim of this protocol study is to describe the methodology of a randomized, controlled, clinical trial comparing the effect of motor physical therapy combined with NMES on the tibialis anterior

    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

  4. When and in which patients can anticoagulation be resumed after intracerebral haemorrhage?

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Whether to resume the anticoagulant or the antiaggregant therapy after an episode of major haemorrhage is a difficult dilemma for the physician. The physician has to take into consideration two major questions: whether the benefits of restarting anticoagulation outweigh the risk, and if so, when and how should anticoagulation be restarted. Although some case reports suggest that anticoagulation can be withheld safely for short periods after ICH, even in patients with mechanical heart valves, it is still not clear if long-term anticoagulation can be safely reinstituted after haemorrhage, for example in patients with atrial fibrillation. In fact, no large and well-conducted randomised clinical trials are available, and there is lack of strong evidence on which guidelines recommendations can be based. The article summarise the available literature findings. Finally, a protocol is suggested which may represent a useful tool for assessing treatment options.

    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

    Full Text Available Advising women on , haemorrhage in pregnancy could, be viewed, as an integral aspect of maternal health care in M alawi. The WHO (1999 confirmed, that haemorrhage in pregnancy was not only a direct reason for maternal mortality but also a major cause of maternal death. The question on the nature of information that midwives and traditional birth attendants (referred to as TBA’s in the Chiradzulu district in Malawi gave with regard to haemorrhage in pregnancy, therefore arose. Research available focused on the women’s knowledge about the complications of pregnancy but not on the nature of information women received from midwives and TBA’s. This study explored and described the nature of information that was given to rural women in the Chiradzulu district by the midwives and TBA’s regarding haemorrhage in pregnancy. The findings revealed that although both the midwives and TBA’s included important information about haemorrhage in pregnancy, there were deficiencies in some critical areas. Examples of these deficiencies were the definition of haemorrhage in pregnancy; the predisposing factors for antepartum and postpartum haemorrhage and deficiencies in the nature of information on the management and referral of haemorrhaging patients. The findings provided insights into the nature of the information that was provided to the women regarding haemorrhage in pregnancy in the Chiradzulu district in Malawi. Thereafter guidelines were developed for the provision of this information. Finally a follow-up study was recommended after implementation of these guidelines in the district to evaluate the change in the nature of the information communicated to patients regarding haemorrhage by midwives and TBA’s. In this study, haemorrhage during pregnancy referred to the perinatal phase, including antepartum, intrapartum and postpartum haemorrhage.

  7. Increased adaptation rates and reduction in trial-by-trial variability in subjects with Cerebral Palsy following a multi-session locomotor adaptation training

    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.

    We report specific changes bilaterally in the basal ganglia and thalamus following reperfusion after complete cerebral ischaemia. A 69-year-old man, resuscitated after cardiac arrest, showed symmetrical low-density lesions in the head of the caudate nucleus and lentiform nucleus on CT. MRI revealed methaemoglobin derived from minor haemorrhage in the basal ganglia and thalamus, not evident on CT. We suggest that this haemorrhage results from diapedesis of red blood cells through the damaged capillary endothelium following reperfusion. (orig.)

    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.

    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.

    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. The training load was gradually increased based on the child's maximum level of strength, as determined by the 8 Repetition Maximum (8 RM. 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. Spasticity and range of motion were assessed to evaluate any

    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.

    Full Text Available Context:Eye-movement training (EMT can induce altered brain activation and change the functionality of saccades with changes of the brain in general. Objective:To determine if EMT would result in changes in qEEG and NIH Stroke Scales (NIHSS in patients suffering from acute middle cerebral artery (MCA infarction. Our hypothesis is that there would be positive changes in qEEG and NIHSS after EMT in patients suffering from acute MCA ischemic stroke.Design:Double blind randomized controlled trial.Setting and Participants:34 subjects with acute MCA ischemic stroke at university affiliated hospital intensive care unit.Interventions:Subjects were randomized into a control group treated only with aspirin (125 mg/day and a treatment group treated with aspirin (125 mg/day and a subject specific EMT. Main Outcome measures: Delta-Alpha Ratio, Power Ratio Index and the Brain Symmetry Index calculated by quantitative electroencephalograms, and NIHSS. Results:There was strong statistical and substantive significant improvement in all outcome measures for the group of stroke patients undergoing EMT. Such improvement was not observed for the control group and there were no adverse effects.Conclusions:The addition of EMT to a MCA ischemic stroke treatment paradigm has demonstrated statistically significant changes in outcome measures and is a low cost, safe and effective complement to standard treatment.

    2007-10-01

    Full Text Available Abstract Background There is a paucity of clinical studies focused specifically on intracerebral haemorrhages of subcortical topography, a subject matter of interest to clinicians involved in stroke management. This single centre, retrospective study was conducted with the following objectives: a to describe the aetiological, clinical and prognostic characteristics of patients with thalamic haemorrhage as compared with that of patients with internal capsule-basal ganglia haemorrhage, and b to identify predictors of in-hospital mortality in patients with thalamic haemorrhage. Methods Forty-seven patients with thalamic haemorrhage were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 17 years. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The region of the intracranial haemorrhage was identified on computerized tomographic (CT scans and/or magnetic resonance imaging (MRI of the brain. Results Thalamic haemorrhage accounted for 1.4% of all cases of stroke (n = 3420 and 13% of intracerebral haemorrhage (n = 364. Hypertension (53.2%, vascular malformations (6.4%, haematological conditions (4.3% and anticoagulation (2.1% were the main causes of thalamic haemorrhage. In-hospital mortality was 19% (n = 9. Sensory deficit, speech disturbances and lacunar syndrome were significantly associated with thalamic haemorrhage, whereas altered consciousness (odds ratio [OR] = 39.56, intraventricular involvement (OR = 24.74 and age (OR = 1.23, were independent predictors of in-hospital mortality. Conclusion One in 8 patients with acute intracerebral haemorrhage had a thalamic hematoma. Altered consciousness, intraventricular extension of the hematoma and advanced age were determinants of a poor early outcome.

    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.

    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.

    Full Text Available Pasteurella multocida is associated with hemorrhagic septicaemia in cattle and buffaloes, pneumonic pasteurellosis in sheep and goats, fowl cholera in poultry, atrophic rhinitis in pigs and snuffles in rabbits. Haemorrhagic septicaemia is caused by Pasteurella multocida type B:2, B:2,5 and B:5 in Asian countries and type E:2 in African countries. Pasteurella multocida have five types of capsular serotype i.e. type A, B, D, E and F. Diagnosis of the disease is mainly based on the clinical sign and symptom, post mortem findings. Confirmatory diagnosis is done by isolation and identification of causative agent. A variety of laboratory diagnostic techniques have been developed over the years for pasteurellosis and used routinely in the laboratory. Among these techniques molecular techniques of diagnosis is most important. This technique not only gives diagnosis but it also provides information regarding capsular type of Pasteurella multocida. Techniques which are used for molecular diagnosis of haemorrhagic septicaemia are PCR based diagnosis, Restriction endonuclease analysis (REA, Ribotyping, Colony hybridization assay, Filled alternation gel electrophoresis (FAGE, Detection of Pasteurella multocida by Real Time PCR. Among these techniques real time PCR is most sensitive and specific. [Vet. World 2011; 4(4.000: 189-192

    Full Text Available Mental Retardation (MR is a developmental disability characterized by impairments in adaptive daily life skills and difficulties in social and interpersonal functioning. Since multiple causes may contribute to MR, associated clinical pictures may vary accordingly. Nevertheless, when psychiatric disorders as Treatment Resistant Depression (TRD and/or alcohol abuse co-exist, their proper detection and management is often troublesome, essentially due to a limited vocabulary MR people could use to describe their symptoms, feelings and concerns, and the lack of reliable screening tools. Furthermore, MR people are among the most medicated subjects, with (over prescription of antidepressants and/or typical antipsychotics being the rule rather than exception. Thus, treatment resistance or even worsening of depression, constitute frequent occurrences. This report describes the case of a person with MR who failed to respond to repetitive trials of antidepressant monotherapies, finally recovering using aripiprazole to fluvoxamine augmentation upon consideration of a putative bipolar diathesis for “agitated” TRD. Although further controlled investigations are needed to assess a putative bipolar diathesis in some cases of MR associated to TRD, prudence is advised in the long-term prescription of antidepressant monotherapies in such conditions.

    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.)

    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.)

    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.

    Single photon emission computed tomography (SPECT) was used to study redistribution of N-isopropyl-[[sup 123]I]-p-iodoamphetamine (IAMP) in 10 patients with intracerebral haemorrhage and 7 with ischaemic stroke. Delayed/early IAMP uptake ratios (D/E) were calculated for four different cerebral zones: haematoma or infarct, perilesional, normal and crossed cerebellar diaschisis areas. Delayed uptake was observed in all areas, but there were no significant differences between the haematoma and infarct results nor between the lesional and perilesional results. Delayed redistribution of IAMP therefore did not seem to be associated with neuronal metabolic activity. (Author).

    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).

    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.

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

    Directory of Open Access Journals (Sweden)

    2016-05-01

    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.

  11. Increased serum levels of interleukin 6 are associated with severe intraventricular haemorrhage in extremely premature infants

    2003-01-01

    Background: Intraventricular haemorrhage (IVH) and periventricular leucomalacia (PVL) in premature infants presumably have many causes. It has been proposed that inflammatory processes in the fetomaternal unit play an important role in the pathogenesis of these lesions. Objective: To study the correlation of postpartum serum interleukin 6 (IL6) concentration as a marker of inflammation and neonatal cerebral morbidity in preterm infants 100 pg/ml. Ultrasound studies and clinical assessment were performed routinely. Results: IVH was noted significantly more often in group B (24/38; 63%) than in group A (19/50; 38%) (p = 0.02). In a multiple logistic regression model, raised serum IL6 independently predicted development of severe IVH (odds ratio 8.4; 95% confidence interval 2.85 to 24.9; p = 0.0001). Conclusions: Raised serum IL6 may serve as a marker for severe IVH in infants < 28 weeks of gestational age. Although cerebral morbidity in premature infants is determined by different variables, the identification of systemic inflammation can help to define the need for anti-inflammatory strategies to prevent cerebral morbidity.

    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.

    With increasing prevalence due to an ageing population, carotid artery stenosis is a significant cause of stroke morbidity and mortality. The indication for revascularisation treatment in symptomatic carotid stenosis is widely documented and accepted in the scientific community. However, treatment of asymptomatic carotid stenosis remains controversial. We report a case of a 78-year-old woman who was admitted with a convexity subarachnoid haemorrhage (cSAH) secondary to an asymptomatic high-grade carotid artery stenosis. Two months later, she suffered an atherothrombotic ischaemic stroke and was referred to surgery. Transcranial Doppler studies showed impaired cerebral vasoreactivity and, after endarterectomy, the patient developed a reperfusion syndrome; both findings consisting of exhausted collaterals as the underlying mechanism. We propose that cSAH secondary to a high-grade internal carotid artery stenosis is a high risk marker for stroke, and revascularisation therapy should be considered.

    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.

    An immigrant from Romania was referred to the neurosurgical unit with a cerebral abscess. On examination she was cyanosed and had clubbing of her fingers. A cardiovascular system examination revealed a systolic murmur heard all over the precordium. However, the diagnosis was not congenital cyanotic heart disease. The patient had a history of frequent nosebleeds and had multiple telangiectases on her body, leading to the diagnosis of hereditary haemorrhagic telangiectasia (HHT). A search was carried out for the presence of arteriovenous malformations in internal organs. Large arteriovenous malformations were found in the lungs, causing her cyanosis due to right-to-left shunting of blood and cerebral abscess due to paradoxical septic embolisation into cerebral circulation.

    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

    Hospitals must have a major haemorrhage protocol in place and this should include clinical, laboratory and logistic responses. Immediate control of obvious bleeding is of paramount importance (pressure, tourniquet, haemostatic dressings). The major haemorrhage protocol must be mobilised immediately when a massive haemorrhage situation is declared. A fibrinogen 1.5 times normal represents established haemostatic failure and is predictive of microvascular bleeding. Early infusion of fresh frozen plasma (FFP; 15 ml.kg−1) should be used to prevent this occurring if a senior clinician anticipates a massive haemorrhage. Established coagulopathy will require more than 15 ml.kg−1 of FFP to correct. The most effective way to achieve fibrinogen replacement rapidly is by giving fibrinogen concentrate or cryoprecipitate if fibrinogen is unavailable. 1:1:1 red cell:FFP:platelet regimens, as used by the military, are reserved for the most severely traumatised patients. A minimum target platelet count of 75 × 109.l−1 is appropriate in this clinical situation. Group-specific blood can be issued without performing an antibody screen because patients will have minimal circulating antibodies. O negative blood should only be used if blood is needed immediately. In hospitals where the need to treat massive haemorrhage is frequent, the use of locally developed shock packs may be helpful. Standard venous thromboprophylaxis should be commenced as soon as possible after haemostasis has been secured as patients develop a prothrombotic state following massive haemorrhage. PMID:20963925

  6. Cerebral malaria Malaria cerebral

    Full Text Available 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. 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.

    Most surgeons have adopted damage control surgery for severely injured patients, in which the initial operation is abbreviated after control of bleeding and contamination to allow ongoing resuscitation in the intensive-care unit. Developments in early resuscitation that emphasise rapid control of bleeding, restrictive volume replacement, and prevention or early management of coagulopathy are making definitive surgery during the first operation possible for many patients. Improved topical haemostatic agents and interventional radiology are becoming increasingly useful adjuncts to surgical control of bleeding. Better understanding of trauma-induced coagulopathy is paving the way for the replacement of blind, unguided protocols for blood component therapy with systemic treatments targeting specific deficiencies in coagulation. Similarly, treatments targeting dysregulated inflammatory responses to severe injury are under investigation. As point-of-care diagnostics become more suited to emergency environments, timely targeted intervention for haemorrhage control will result in better patient outcomes and reduced demand for blood products. Our Series paper describes how our understanding of the roles of the microcirculation, inflammation, and coagulation has shaped new and emerging treatment strategies.

    The 6 cases reported here constitute, with 5 previously published cases, a special nosological entity tentatively called "acute benign cerebral angiopathy" by the authors. These 11 cases have in common certain radiological and clinical features. Arteriography shows segmental, multifocal and assymetrical stenoses involving the cerebral arteries between Willis' circle and the terminal arterioles and looking like "strings of sausages". The lesions disappear within one month and present the radiological characteristics of arteritis of medium caliber vessels. The clinical symptoms are suggestive of meningeal haemorrhage or acute cerebromeningeal oedema, with acute repetitive attacks of severe headache and agitation with obnubilation; epileptic seizures and transient neurological deficit may occur. True meningeal haemorrhage confirmed by lumbar puncture is seen in nearly one half of the cases; it seems to be due to alterations in the blood-brain barrier induced by the angiopathy. Intracerebral haematoma may develop, but the disease is usually benign and regresses spontaneously in a few days. None of the usual causes of cerebral arteritis (intra-cranial infection, collagen disease, allergic or toxic angitis) has been found. Pseudo-arteritis (notably spasm of ruptured arterial aneurysms) has been excluded. No aetiological factor common to the 11 cases reported has been elicited, although 6 of the patients had recently given birth and our 6 patients had benign virus infection before or during the clinical manifestations of the disease. In the authors' opinion, the most rewarding line of research would be the role of short acute attacks of arterial hypertension.

    We aim to determine if direct thrombin inhibition by dabigatran will improve long-term brain morphological and neurofunctional outcomes and if potential therapeutic effects are dependent upon reduced PAR-1 stimulation and consequent mTOR activation. Germinal matrix haemorrhage was induced by stereotaxically injecting 0.3 U type VII-S collagenase into the germinal matrix of P7 rat pups. Animals were divided into five groups: sham, vehicle (5% DMSO), dabigatran intraperitoneal, dabigatran intraperitoneal + TFLLR-NH2 (PAR-1 agonist) intranasal, SCH79797 (PAR-1 antagonist) intraperitoneal, and dabigatran intranasal. Neurofunctional outcomes were determined by Morris water maze, rotarod, and foot fault evaluations at three weeks. Brain morphological outcomes were determined by histological Nissl staining at four weeks. Expression levels of p-mTOR/p-p70s6k at three days and vitronectin/fibronectin at 28 days were quantified. Intranasal and intraperitoneal dabigatran promoted long-term neurofunctional recovery, improved brain morphological outcomes, and reduced intracranial pressure at four weeks after GMH. PAR-1 stimulation tended to reverse dabigatran's effects on post-haemorrhagic hydrocephalus development. Dabigatran also reduced expression of short-term p-mTOR and long-term extracellular matrix proteins, which tended to be reversed by PAR-1 agonist co-administration. PAR-1 inhibition alone, however, did not achieve the same therapeutic effects as dabigatran administration.

  13. T cell responses and dengue haemorrhagic fever.

    The enhancement of severe disease upon secondary infection makes dengue almost unique among infectious pathogens and presents a serious challenge to vaccine design. Several key observations have been made which shed light onto this phenomenon particularly that antibodies can enhance Fc receptor-dependent uptake of virus into macrophages thereby increasing virus replication. Furthermore there seems to be a relationship between the peak virus load and disease severity. However, a second key feature of dengue is that the life-threatening symptoms do not correlate with the period of high viraemia; instead they occur at a time when the virus load is in steep decline. The coincidence of severe disease manifestations with defervescence and virus control suggests that the symptoms may be a consequence of the immune response to the virus rather than virus induced cytopathology. One of the key elements in the immune response to viruses are T cells which can both secrete a host of inflammatory cytokines and also be directly cytotoxic to infected cells. There are a number of experimental models of T cell-induced immunopathology including in responses to viruses. Particularly interesting in this respect are models of RSV-induced immunopathology, which have direct relevance to vaccine design as a formalin-inactivated vaccine to RSV actually enhanced disease in children when they became naturally infected with RSV, an echo of the disease enhancement seen in dengue. We will present an analysis of CD8+ T cell responses to a number of novel T cell epitopes during dengue infection and also analyse the function and cytokine secretion of these cells. We suggest that an exaggerated and partially misdirected T cell response seen in secondary dengue infection may be part of the complex series of events leading to dengue haemorrhagic fever and shock.

    2011-08-01

    Full Text Available Abstract Background Subarachnoid haemorrhage (SAH elicits rapid pathological changes in the structure and function of parenchymal vessels (≤ 100 μm. The role of neutrophils in these changes has not been determined. This study investigates the role of neutrophils in early microvascular changes after SAH Method Rats were either untreated, treated with vinblastine or anti-polymorphonuclear (PMN serum, which depletes neutrophils, or treated with pyrrolidine dithiocarbamate (PDTC, which limits neutrophil activity. SAH was induced by endovascular perforation. Neutrophil infiltration and the integrity of vascular endothelium and basement membrane were assessed immunohistochemically. Vascular collagenase activity was assessed by in situ zymography. Results Vinblastine and anti-PMN serum reduced post-SAH accumulation of neutrophils in cerebral vessels and in brain parenchyma. PDTC increased the neutrophil accumulation in cerebral vessels and decreased accumulation in brain parenchyma. In addition, each of the three agents decreased vascular collagenase activity and post-SAH loss of vascular endothelial and basement membrane immunostaining. Conclusions Our results implicate neutrophils in early microvascular injury after SAH and indicate that treatments which reduce neutrophil activity can be beneficial in limiting microvascular injury and increasing survival after SAH.

    Only 15% of all subarachnoid haemorrhages (SAHs) are not of aneurysmal origin. Among those, circumscribed SAHs along the cortical convexity are rare and have only been described in singular case reports so far. Here, we present a collection of 12 cases of SAH along the convexity, of non-traumatic origin. Over a period of 10 years, 12 cases of circumscribed SAH along the convexity were identified at our clinic. The clinical presentations, neuroradiological SAH characteristics, further diagnostic work-up to identify the underlying aetiologies, the therapy and clinical outcome were analysed. The patients' chief complaints were unspecific cephalgia, focal or generalised seizures and focal neurological deficits. Typical signs of basal SAH, such as nuchal rigidity, thunderclap-headache or alteration of consciousness, were rare. Magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) revealed different aetiologies, namely postpartal posterior encephalopathy (three), cerebral vasculitis (two), dural sinus thrombosis (two), cortical venous thrombosis (one), intracerebral abscesses (one) and cerebral cavernoma (one). Two cases remained unresolved. Treatment of the underlying disease and symptomatic medication led to good clinical outcome in almost all cases. On the basis of these findings, we demonstrate that the clinical presentation, localisation and aetiology of cortical SAH differ clearly from other SAHs. A diagnostic work-up with MRI and eventually DSA is essential. Mostly, the causative disease can be identified, and specific treatment allows a favourable outcome. (orig.)

    Full Text Available Abstract Background Few studies demonstrate effectiveness of therapies for oral rehabilitation of patients with cerebral palsy (CP, given the difficulties in chewing, swallowing and speech, besides the intellectual, sensory and social limitations. 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.

    2012-01-01

    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.

    2014-01-17

    Haemorrhagic cholecystitis is a rare cause of upper gastrointestinal bleeding and is a difficult diagnosis to make. This case report describes an orthopaedic patient, who developed deranged liver function tests and anaemia after a hemiarthroplasty of the hip. The patient had upper abdominal pain and black stools which clinically appeared to be melaena. An ultrasound scan of the abdomen was inconclusive, and therefore a CT was performed and the potential diagnosis of haemorrhagic cholecystitis was raised. An endoscopic evaluation of the upper gastrointestinal tract showed no evidence of other causes of upper gastrointestinal bleeding. Following an emergency laparotomy and cholecystectomy, she recovered well. This report aims to increase awareness about the uncommon condition of haemorrhagic cholecystitis, and to educate regarding clinical and radiological signs which lead to this diagnosis.

    This paper reports a second outbreak of acute haemorrhagic conjunctivitis due to coxsackievirus A24 in peninsular Malaysia. Between June 2002 and early October 2003, 10,327 patients, comprising 3,261 children and 7,066 adults, were treated for acute conjunctivitis in 11 government health clinics in the Melaka Tengah district of the state of Melaka. The figure grossly underestimates the size of the outbreak; as no patients treated in private clinics in the same district were included. Institution and household surveillance showed that the commonest presenting clinical feature of the illness was eye-discharge (91.2%), followed by foreign body sensation (81.8%), pain (78.3%) and subconjunctival haemorrhage (74.4%). The mean duration of illness was 6.5 and five days for patients with and without subconjunctival haemorrhage respectively.

    Objective To study the safety and efficacy of intensive reduction of blood pressure for the treatment of acute cerebral haemorrhage. Method A randomized control trial in 41 consecutive patients with intracerebral haemorrhage admitted from October 2006 to January 2007 were randomly assigned to intensive blood pressure reduction group ( n = 24) or guidelines blood pressure reduction group ( n = 17) (tho guidelines set by American Association of cardiologists). In the intensive reduction group, the systolic pressure was reduced immediately to lower than 140 mmHg, while the blood pressure was reduced to that just below 180 mmHg in guideline reduction group. The size of the haematoma was measured 24 h after treatment by CT scans and the patients were followed up for 90 days. Death and/or disability in 90 days, and the short-term and long-term neurological function and the size of haematoma in 24 hours of two groups were compared. The outcomes were statistically analyzed with SPSS version 10.0 software. Measurement data were analyzed with t -test while numeration data were analyzed with chisquare test. Results There were no significant differences either in death and/or disability or in short-term and long-term neurological function in 90 days after treatment ( P > 0.05). The mean values of proportional enlargement of haematoma were 16.8% in the intensive group and 36. 1% in the guidelines group 24 hours after treatment ( P = 0.012). The mean values of absolute enlargement of haematoma of two groups were 2.7 mL and 5. 1 mL,respectively (P = 0.058). There was significant difference in rate of enlargement of haematoma in the early stage of acute cerebral haemorrhage (4.2% vs. 47. 1%, P = 0.012). Conclusions Although intensive reduction of blood pressure in patients with acute cerebral haemorrhage did not alter the clinical prognosis of patients, it could apparently attenuate the enlargement of haematoma in the early stage of acute cerebral haemorrhage.%目的 比较脑

    Duplication cysts of the gastrointestinal tract are rare congenital abnormalities. Ectopic gastric mucosa, which can be found in duplications, may cause peptic ulceration, gastrointestinal bleeding or perforation. We report a 1-year-old boy with a perforated ileal duplication cyst with haemorrhagic pseudocyst formation caused by peptic ulceration of the duplication cyst. It presented a snowman-like appearance consisting of a small, thick-walled, true enteric cyst and a large, thin-walled haemorrhagic pseudocyst on US and CT. It is an unusual manifestation of a duplication cyst, which has not been reported in the English language literature. (orig.)

    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.

    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.

    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.

  16. Transfusion practice in major obstetric haemorrhage: lessons from trauma.

    Science.gov (United States)

    Saule, I; Hawkins, N

    2012-01-01

    The management of massive haemorrhage with blood products is changing as evidence arrives from civilian and military trauma. Rapid early replacement of coagulation factors and platelets is now becoming central to improving outcome, usually given in higher ratios with respect to red cell units than previously recommended and using empiric transfusion based on clinical rather than laboratory parameters. The management of three cases of major obstetric haemorrhage based on these principles is presented. Packed red blood cells, fresh frozen plasma, platelets and cryoprecipitate were transfused in the ratios 5:2:2:1, 4.5:1:1:1 and 4.5:2:1:1. Each patient had acceptable full blood count and coagulation results after surgery and all made an uneventful recovery. These outcomes support the opinion that major obstetric haemorrhage can be managed in a similar fashion to blood loss in trauma. Recommendations from the Association of Anaesthetists of Great Britain and Ireland, and the UK National Patient Safety Agency should be considered during major obstetric haemorrhage.

    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.

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.

    This work is the product of the checking of the pathogenesis, incidence, treatment, and prognostic of the intraventricular hemorrhage in the premature newborn. In the revised publications, that include important series of following, this pathology is present in 25% of the infants weighing less than 1,500 g, in which the mortality and morbidity is greater than that of normal newborns, since the development of intraventricular hemorrhage can produce alterations of cerebral blood flow in the immature germinal matrix and in the microvascular net. In consequence the prevention of the intraventricular hemorrhage is directly related with its pathogenesis. It is said that the use of dexamethasone steroids in low doses in the prenatal period, and low doses of indomethacin in the postnatal period, can give better neuroprotection. The surgical treatment is exceptional and has very precise indications, when a progresive hydrocephalus of later apparition is proven. Therefore in premature newborns with intraventricular hemorrhage the best actual treatment is to use an appropiate pharmacological and medical following

    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.

    [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

    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.

    Betjes, M G; Koopmans, R P

    2000-03-18

    Hyponatraemia is a frequent finding in the course of an acute intracranial disease, especially after a subarachnoid haemorrhage. The fall in plasma sodium concentration is usually mild and not below 124 mmol/l but may reach dangerously low levels with serious neurological complications. In the early 1950s the cause of the hyponatraemia was believed to be primarily excessive natriuresis and therefore named 'cerebral salt wasting'. After the description of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) this was favoured as the most likely explanation. Only in recent years has it become evident that many hyponatraemic patients with acute brain disease are actually hypovolaemic. This is compatible with the original diagnosis of cerebral salt wasting. The increased plasma concentrations of natriuretic peptides are likely to mediate the increased natriuresis. Cerebral salt wasting can be treated with a simple regimen of water and salt suppletion. If needed a mineralocorticoid like fludrocortisone can be given to increase renal tubular sodium reabsorption.

    1998-10-01

    The aim of the study is to prove, retrospectively, that it is unlikely that the computerized tomography (CT) diagnosis of subarachnoid haemorrhage (SH) accompanies the CT diagnosis of generalized brain edema. A total of 100 comatose patients underwent CT of the brain. Of this number, 42 underwent an enhanced CT scan. In 26 patients, lumbar puncture was also performed. A control group of ten patients diagnosed with headache and having a normal CT scan underwent NECT and ECT. Measurements of the white and gray matter density in Hounsfield units (HU) were performed in all 110 cases, including the controls. The brain tissue density and the difference between the densities of the white and gray matter were lower in the cases with brain edema than in the controls. The data values were statistically significant. Small cerebral ventricles, sulci and cisterns and small differences between white and gray matter measurements were observed in the CT scans of the brain edema cases. All 100 patients had CT diagnosis of brain edema and SH. There was no bloody or xanthochromic CSF in any of the 26 lumbar punctures performed. In the enhanced CT scans, there was poor or no filling of the lateral sinuses. The compression of the lateral sinuses by the edematous brain tissue most probably results in their stenosis or obstruction due to disturbed brain venous drainage which can mimic CT findings of SH.

    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.

    Full Text Available Malaria-leptospira co-infection is rarely detected. Emergency surgery in such patients has not been reported. We describe such a case of a 24-year-old primigravida at term pregnancy posted for emergency caesarean delivery who developed pulmonary haemorrhage, acute respiratory distress syndrome, acute kidney injury, and cerebral oedema. Here, we discuss the perioperative management, pain management (with transverse abdominis plane block, intensive care management (special reference to management of pulmonary haemorrhage with intra pulmonary factor VIIa and the role of plasmapheresis in leptospira related jaundice with renal failure.

    Full Text Available Spontaneous intracerebral haemorrhage is a devastating form of stroke and its incidence increases with age. Obtaining brain tissue following intracerebral haemorrhage helps to understand its cause. Given declining autopsy rates worldwide, the feasibility of establishing an autopsy-based collection and its generalisability are uncertain.We used multiple overlapping sources of case ascertainment to identify every adult diagnosed with intracerebral haemorrhage between 1st June 2010-31st May 2012, whilst resident in the Lothian region of Scotland. We sought consent from patients with intracerebral haemorrhage (or their nearest relative if the patient lacked mental capacity to conduct a research autopsy.Of 295 adults with acute intracerebral haemorrhage, 110 (37% could not be approached to consider donation. Of 185 adults/relatives approached, 91 (49% consented to research autopsy. There were no differences in baseline demographic variables or markers of intracerebral haemorrhage severity between consenters and non-consenters. Adults who died and became donors (n = 46 differed from the rest of the cohort (n = 249 by being older (median age 80, IQR 76-86 vs. 75, IQR 65-83, p = 0.002 and having larger haemorrhages (median volume 23 ml, IQR 13-50 vs. 13 ml, IQR 4-40; p = 0.002.Nearly half of those approached consent to brain tissue donation after acute intracerebral haemorrhage. The characteristics of adults who gave consent were comparable to those in an entire community, although those who donate early are older and have larger haemorrhage volumes.

    2013-04-01

    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.

    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, a complementary treatment that manipulates muscle and fascia, would improve gross motor function and gait in children 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 time × group 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.

    Intraventricular haemorrhage (IVH) is a serious complication in premature infants. This type of bleeding may lead to serious neurological sequelae or even death. IVH is prevalent in VLBW children, with an incidence of 30%. Recent research shows a significant relationship between low cerebral blood flow and IVH. The most common way to measure blood flow is to measure blood pressure. However, studies suggest that a more correct method is to measure the SVC (Superior vena cava) flow. The SV...

    Full Text Available BACKGROUND: Postpartum haemorrhage is a leading cause of maternal morbidity and mortality worldwide. Identifying risk indicators for postpartum haemorrhage is crucial to predict this life threatening condition. Another major contributor to maternal morbidity and mortality is pre-eclampsia. Previous studies show conflicting results in the association between pre-eclampsia and postpartum haemorrhage. The primary objective of this study was to investigate the association between pre-eclampsia and postpartum haemorrhage. Our secondary objective was to identify other risk indicators for postpartum haemorrhage in the Netherlands. METHODS: A nationwide cohort was used, containing prospectively collected data of women giving birth after 19 completed weeks of gestation from January 2000 until January 2008 (n =  1,457,576. Data were extracted from the Netherlands Perinatal Registry, covering 96% of all deliveries in the Netherlands. The main outcome measure, postpartum haemorrhage, was defined as blood loss of ≥1000 ml in the 24 hours following delivery. The association between pre-eclampsia and postpartum haemorrhage was investigated with uni- and multivariable logistic regression analyses. RESULTS: Overall prevalence of postpartum haemorrhage was 4.3% and of pre-eclampsia 2.2%. From the 31 560 women with pre-eclampsia 2 347 (7.4% developed postpartum haemorrhage, compared to 60 517 (4.2% from the 1 426 016 women without pre-eclampsia (odds ratio 1.81; 95% CI 1.74 to 1.89. Risk of postpartum haemorrhage in women with pre-eclampsia remained increased after adjusting for confounders (adjusted odds ratio 1.53; 95% CI 1.46 to 1.60. CONCLUSION: Women with pre-eclampsia have a 1.53 fold increased risk for postpartum haemorrhage. Clinicians should be aware of this and use this knowledge in the management of pre-eclampsia and the third stage of labour in order to reach the fifth Millenium Developmental Goal of reducing maternal mortality ratios with 75% by

    Hyponatraemia is a common complication in patients undergoing neurosurgery. It can be caused either by the syndrome of inappropriate secretion of antidiuretic hormone or by the cerebral salt-wasting syndrome (CSWS). CSWS frequently occurs in patients suffering from subarachnoid haemorrhage and brain injury, but it is rare after pituitary tumour surgery. However, this diagnostic possibility should be considered as these disorders require specific treatment and have different prognoses. In this article, we present a case of acute and early hyponatraemia caused by CSWS after pituitary tumour surgery. We also revise the aetiology, mechanisms, differential diagnosis and treatment of hyponatraemia after pituitary surgery.

En esta revisión hemos realizado un enfoque global para el manejo de una gestante que acude a urgencias por un sangrado vaginal, y posteriormente de manera más específica el manejo de algunas de las entidades más frecuentes de la hemorragia obstétrica. 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.

    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. Primary outcome is the capability of functional skills in self-care and mobility, using the Functional Skills Scale of the Pediatric Evaluation of Disability Inventory (PEDI.

    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

    Objectives To record the current use of tranexamic acid during traumatic haemorrhage and elective arthroplasty of the hip and knee. Design A questionnaire-based postal survey. Setting The questionnaire was sent to the ‘anaesthetic lead’ at all acute trusts in England, excluding centres for children, women’s health, cancer and cardiac care. Participants Ninety-nine (66%) centres replied to the questionnaire. Main outcome measures Is tranexamic acid used as part of routine standardized treatment for traumatic haemorrhage and for elective hip and knee arthroplasty, and if so what dosage regime was administered? Results Few trusts (31%) use tranexamic acid during traumatic haemorrhage, with various dosages used. Its use in hip and knee arthroplasty was also low (38%) with a diverse range of doses prescribed. Conclusions Despite many trials showing its efficacy and low risk of side effect, it is clear that its use is not part of standard practice in most centres. Further studies could clarify these concerns and provide a definitive dosing schedule improving patient care and saving lives. PMID:25057371

    Postpartum haemorrhage is one of the major causes of maternal mortality worldwide. The leading cause of primary postpartum haemorrhage is uterine atony and active management of the third stage of labour with oxytocin is recommended for preventing primary postpartum haemorrhage. Parenteral oxytocin is also the drug of choice for medical management of postpartum haemorrhage secondary to uterine atony. Condom uterine balloon tamponade is .a low cost technique that can be used as a second-line option for treatment. We report retrospectively three cases of primary PPH secondary to uterine atony which were managed successfully with condom tamponade. Condom tamponade is effective in managing post partum haemorrhage secondary to uterine atony and we advocate for the training of all skilled attendants on how to insert the condom tamponade.

    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.)

    Single-switch access in conjunction with scanning remains a fundamental solution in restoring communication for many children with profound physical disabilities. However, untimely switch inaction and unintentional switch activations can lead to user frustration and impede functional communication. A previous preliminary study, in the context of a case series with three single-switch users, reported that correct, accidental and missed switch activations could elicit cardiac deceleration and increased phasic skin conductance on average, while deliberate switch non-use was associated with autonomic nonresponse. The present study investigated the possibility of using blood volume pulse recordings from the same three pediatric single-switch users to track the aforementioned switch events on a single-trial basis. Peaks of the line length time series derived from the empirical mode decomposition of the inter-beat interval time series matched, on average, a high percentage (above 80%) of single-switch events, while unmatched peaks coincided moderately (below 37%) with idle time during scanning. These results encourage further study of autonomic measures as complementary information channels to enhance single-switch access.

    Haemorrhagic stroke accounts for ∼20% of stroke cases and porencephaly is a clinical consequence of perinatal cerebral haemorrhaging. Here, we report the identification of a novel dominant G702D mutation in the collagen domain of COL4A2 (collagen IV alpha chain 2) in a family displaying porencephaly with reduced penetrance. COL4A2 is the obligatory protein partner of COL4A1 but in contrast to most COL4A1 mutations, the COL4A2 mutation does not lead to eye or kidney disease. Analysis of dermal biopsies from a patient and his unaffected father, who also carries the mutation, revealed that both display basement membrane (BM) defects. Intriguingly, defective collagen IV incorporation into the dermal BM was observed in the patient only and was associated with endoplasmic reticulum (ER) retention of COL4A2 in primary dermal fibroblasts. This intracellular accumulation led to ER stress, unfolded protein response activation, reduced cell proliferation and increased apoptosis. Interestingly, the absence of ER retention of COL4A2 and ER stress in cells from the unaffected father indicate that accumulation and/or clearance of mutant COL4A2 from the ER may be a critical modifier for disease development. Our analysis also revealed that mutant collagen IV is degraded via the proteasome. Importantly, treatment of patient cells with a chemical chaperone decreased intracellular COL4A2 levels, ER stress and apoptosis, demonstrating that reducing intracellular collagen accumulation can ameliorate the cellular phenotype of COL4A2 mutations. Importantly, these data highlight that manipulation of chaperone levels, intracellular collagen accumulation and ER stress are potential therapeutic options for collagen IV diseases including haemorrhagic stroke.

    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.

    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

    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.

    2010-11-01

    Viral haemorrhagic fevers (VHF) are caused by zoonotic viral infections transmitted to humans directly or by ticks or mosquitoes. The overall risk to travellers is conservatively estimated at modern Western hospital settings. However, healthcare-associated transmission of infection has been a major problem in some endemic settings. The potential for healthcare-associated infection and the threats posed by unrecognised or new agents necessitate a high index of suspicion and a standardised risk assessment approach to febrile travellers. Travel-related hantavirus infections are increasingly being reported from Europe and the Americas. This article summarises the epidemiology and reports of travel-related VHF cases in the past 40 years, together with strategies for their recognition, management and prevention.

    Pregnancy is a state of hypercoagulobility that might be an evolutionary way of protecting parturients from exsanguination following child birth. Observational studies suggest an association between a low level of fibrinogen (coagulation factor I) at the start of postpartum haemorrhage (PPH....... Paper III was based on two national Danish registries evaluating the predictability of postpartum blood transfusion. Prediction was found difficult. However, retained placental parts seemed to be the strongest predictor. Since this diagnosis is made very late and often in association with the onset...... of bleeding, tools to perform an early diagnosis is highly warranted. Paper IV includes recommendations of the European Society of Anaesthesiology regarding the use of fibrinogen concentrate in PPH, and is based on very weak (GRADE 2) evidence and low confidence in estimates of effect (GRADE C).

    Full Text Available Functioning of health systems with respect to maternal health were previously audited using indicators like maternal mortality ratio. However, maternal morbidity as a consequence of pregnancy-related complications is not accounted for in these indicators. Thus, the World Health Organization (WHO has formulated a maternal near-miss approach to pregnancy complications for a more thorough evaluation of health care systems across the world. In practical terms, women are said to be maternal near-miss cases when they survive lethal conditions during pregnancy or in the postpartum period. We report one such case of traumatic variety of postpartum haemorrhage subsequent to a lower segment caesarean section with immediate post-operative removal of cervical cerclage threads that resulted in a maternal near-miss case.

    65 patients with negative but technically satisfactory 4 vessel angiography - all admitted to our Department in the years 1976-1983 - were evaluated in the present study. CT scan was undertaken in all cases (in 47 cases within 4 days of haemorrhage). Arterial hypertension was present on admission in 9% of cases. The period of follow-up ranged from 4 to 11 years, with a mean of 5.3 years. The study group was compared to a control group, comprising 760 patients with subarachnoid haemorrhage from ruptured aneurysms, admitted during the same period. Clinical grade on admission (Hunt's classification) was better in patients belonging to the study group. The amount of cisternal deposition on CT scan was less significant than in patients with ruptured aneurysms, and the deposition was often atypical (circumpeduncular, ambiental, and/or tentorial). Clinical deterioration associated with vasospasm was observed in 5% of patients in this study and in 27% of patients in the control group. In patients with a consistent or thick cisternal layer (CT scan "at risk") the incidence of clinical vasospasm was 21%, against 47% in controls. One or more rebleedings occurred in 12% of patients in the study group, against 25% of patients in the control group. A significant ventricular dilatation was observed in 15% of patients in the first group (requiring a shunt in 8%), against 25% of patients in the second group (requiring a shunt in 11%). Final outcome was favourable in 95% of patients in this study group and in 63% of patients in the control group, with a mortality rate of 5% in the first group and 32% in the second group.

    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.

    2017-01-01

    Variceal haemorrhage is a major complication of portal hypertension that still causes high mortality in patients with cirrhosis. Improved knowledge of the pathophysiology of portal hypertension has recently led to a more comprehensive approach to prevent all the complications of this condition. Thus, optimal treatment of portal hypertension requires a strategy that takes into account the clinical stage of the disease and all the major variables that affect the risk of progression to the next stage and death. In patients with compensated liver disease, the correction of factors influencing the progression of fibrosis, in particular aetiologic factors, is now feasible in many cases and should be achieved to prevent the development or progression of gastroesophageal varices and hepatic decompensation. Once gastroesophageal varices have developed, non-selective beta-blockers remain the cornerstone of therapy. Carvedilol provides a greater decrease in portal pressure and is currently indicated as a first-choice therapy for primary prophylaxis. The treatment of acute variceal haemorrhage includes a combination of vasoactive drugs, antibiotics and endoscopic variceal band ligation. In high-risk patients, the early use of transjugular intrahepatic portosystemic shunt (TIPS) lowers the risk of re-bleeding and improves survival. Transjugular intrahepatic portosystemic shunt is the choice for uncontrolled variceal bleeding; a self-expandable metal stent or balloon tamponade can be used as a bridging measure. The combination of non-selective beta-blockers and endoscopic variceal band ligation reduces the risk of recurrent variceal bleeding and improves survival. In these cases, statins seem to further improve survival. Transjugular intrahepatic portosystemic shunt is indicated in patients who rebleed during secondary prophylaxis.

    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.

    Ensuring adequate oxygenation of the developing brain is the cornerstone of neonatal critical care. Despite decades of clinical research dedicated to this issue of paramount importance, our knowledge and understanding regarding the physiology and pathophysiology of neonatal cerebral blood flow are still rudimentary. This review primarily focuses on currently available human clinical and experimental data on cerebral blood flow and autoregulation in the preterm and term infant. Limitations of systemic blood pressure values as surrogates for monitoring adequate cerebral oxygen delivery are discussed. Particular emphasis is placed on the high interindividual variability in cerebral blood flow values, vasoreactivity, and autoregulatory thresholds making the applications of normative values highly questionable. Technical and ethical difficulties to conduct such trials leave us with a near complete lack of knowledge on how pharmacological and surgical interventions impact on cerebral autoregulation. The ensemble of these works argues for the necessity of highly individualized care by taking advantage of continuous bedside monitoring of cerebral circulation. They also point to the urgent need for further studies addressing the exciting but difficult issue of cerebral blood flow autoregulation in the neonate.

    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.)

    Cerebellar haemorrhages are rare life-threatening complications following spine surgery that present challenges for their diagnostic and their therapeutic management. Their patho-physiology remains unclear.We report a case of a life-threatening cerebellar haemorrhage secondary to an occult dural tear following a planned L5-S1 laminectomy. The patient was treated with emergent external ventriculostomy following by a posterior fossa decompressive craniectomy. Cerebellar haemorrhages have to be suspected systematically when unexpected neurological signs occur after spine surgery since their rapid management lead to favourable outcomes. The present imaging findings allow us proposing that cerebellar haemorrhages result primarily from superior cerebellar venous stretching and tearing, and that cerebellar infarction and swelling occur secondarily.

  7. Soluble Toll-Like Receptors 2 and 4 in Cerebrospinal Fluid of Patients with Acute Hydrocephalus following Aneurysmal Subarachnoid Haemorrhage.

    Directory of Open Access Journals (Sweden)

    Bartosz Sokół

    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.

    This study aimed to determine if performing cerebrospinal fluid spectrophotometry in addition to visual inspection detects more ruptured cerebral aneurysms than performing cerebrospinal fluid visual inspection alone in patients with a normal head CT scan but suspected of suffering an aneurysmal subarachnoid haemorrhage (SAH). We performed a single-centre retrospective study of patients presenting to the emergency department of a tertiary hospital who underwent both head CT scan and lumbar puncture to exclude SAH. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of an approach utilising both spectrophotometry and visual inspection (combined approach) was compared to visual inspection alone. A total of 409 patients (mean age 37.8 years, 56.2% female) were recruited and six (1.5%) had a cerebral aneurysm on angiography. The sensitivity of visual inspection was 50% (95% confidence interval [CI]: 12.4-82.6%), specificity was 99% (95% CI: 97.5-99.7%), PPV was 42.9% (95% CI: 10.4-81.3%) and NPV was 99.2% (95% CI: 97.8-99.8%). The combined approach had a sensitivity of 100% (95% CI: 54.1-100%), specificity of 79.7% (95% CI: 75.4-83.5%), PPV of 6.8% (95% CI: 2.6-14.3%) and a NPV of 100% (95% CI: 98.8-100%). The sensitivity of the combined approach was not significantly different to that of visual inspection alone (p=0.25). Visual inspection had a significantly higher specificity than the combined approach (p<0.01). The combined approach detected more cases of aneurysmal SAH than visual inspection alone, however the difference in sensitivity was not statistically significant. Visual xanthochromia should prompt angiography because of a superior specificity and PPV. Due to its reduced sensitivity, caution should be applied when using only visual inspection of the supernatant.

  9. Fish oil diet associated with acute reperfusion related haemorrhage, and with reduced stroke-related sickness behaviours and motor impairment

    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.

    We describe five cases of high signal in the cerebrospinal fluid (CSF) on fast-FLAIR images 24-48 h after onset of stroke. All the patients had undergone perfusion-weighted MRI within 6 h of the onset of the symptoms. The CSF was far brighter than the cortical gyri. The high signal was diffusely around both cerebral hemispheres in two cases and around one hemisphere in two others; it was focal, around the acute ischaemic lesion, in one. CT was normal in all cases. The CSF high signal was transient, decreasing in extent and intensity with time and resolving completely within 3-6 days. It was not associated with worsening of the clinical state or poor outcome. Our explanation of this phenomena is hypothetical: we speculate that it could be due to disruption of the blood-brain barrier resulting in leakage of protein, gadolinium chelates, or both in to the subarachnoid space. It should not be confused with subarachnoid haemorrhage.

    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.

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

    Science.gov (United States)

    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.

  16. Haemostatic monitoring during postpartum haemorrhage and implications for management.

    Solomon, C; Collis, R E; Collins, P W

    2012-12-01

    Postpartum haemorrhage (PPH) is a major risk factor for maternal morbidity and mortality. PPH has numerous causative factors, which makes its occurrence and severity difficult to predict. Underlying haemostatic imbalances such as consumptive and dilutional coagulopathies may develop during PPH, and can exacerbate bleeding and lead to progression to severe PPH. Monitoring coagulation status in patients with PPH may be crucial for effective haemostatic management, goal-directed therapy, and improved outcomes. However, current PPH management guidelines do not account for the altered baseline coagulation status observed in pregnant patients, and the appropriate transfusion triggers to use in PPH are unknown, due to a lack of high-quality studies specific to this area. In this review, we consider the evidence for the use of standard laboratory-based coagulation tests and point-of-care viscoelastic coagulation monitoring in PPH. Many laboratory-based tests are unsuitable for emergency use due to their long turnaround times, so have limited value for the management of PPH. Emerging evidence suggests that viscoelastic monitoring, using thrombelastography- or thromboelastometry-based tests, may be useful for rapid assessment and for guiding haemostatic therapy during PPH. However, further studies are needed to define the ranges of reference values that should be considered 'normal' in this setting. Improving awareness of the correct application and interpretation of viscoelastic coagulation monitoring techniques may be critical in realizing their emergency diagnostic potential.

    To assess the patient outcome after endovascular treatment of delayed post-pancreatectomy haemorrhage (PPH) as first-line treatment. Between January 2005 and November 2013, all consecutive patients referred for endovascular treatment of PPH were included. Active bleeding, pseudoaneurysms, collections and the involved artery were recorded on pretreatment CT. Endovascular procedures were classified as technical success (source of bleeding identified on angiogram and treated), technical failure (source of bleeding identified but incompletely treated) and abstention (no abnormality identified, no treatment performed). Factors associated with rebleeding were analysed. Sixty-nine patients (53 men) were included (mean 59 years old (32-75)). Pretreatment CT showed 27 (39 %) active bleeding. In 22 (32 %) cases, no involved artery was identified. Technical success, failure and abstention were observed in 48 (70 %), 9 (13 %) and 12 patients (17 %), respectively. Thirty patients (43 %) experienced rebleeding. Rebleeding rates were 29 %, 58 % and 100 % in case of success, abstention and failure (p < 0.001). Treatment failure/abstention was the only factor associated with rebleeding. Overall, 74 % of the patients were successfully treated by endovascular procedure(s) alone. After a first endovascular procedure for PPH, the rebleeding rate is high and depends upon the success of the procedure. Most patients are successfully treated by endovascular approach(es) alone.

    Studies on the aetiological agents of rabbit haemorrhagic disease (RHD) and European brown hare syndrome show that the viruses responsible for these infections can be placed in the family Caliciviridae. Established members of this group are vesicular exanthema virus (prototype), San Miguel sea lion virus and feline calcivirus. The human hepatitis E virus and the Norwalk agent may soon be included. The RHD virus genome consists of a positive stranded RNA molecule composed of 7437 nucleotides. A major subgenomic RNA of 2.2 kb, colinear with the 3' end of the genomic RNA, can also be recovered from infected liver tissue, and both RNAs are enclosed within viral capsids formed by a single major protein of approximately 60 kDa. Electron microscopic examination of organ suspensions from diseased animals shows two types of particle; 35-40 nm complete virions have the regularly arranged cup-shaped depressions typical of calcivirus morphology, and 23-25 nm smooth particles resulting from degradation of the outer surface structures of the complete virions.

    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.

    Full Text Available Pasteurella multocida is bacterial pathogens that cause haemorrhagic septicaemia (HS in cattle and buffaloes. Various tests have been used to differentiate types of P. multocida, as well as to diagnose this specific disease. A latex agglutination test has been developed for the detection of P. multocida B:2 which is the causal agent of HS. This test is a rapid and simple test suitable for local laboratorium to diagnose HS cases in the field. A heat stable antigen consisting of mainly lipopolysaccharide (LPS extract of formalin killed P. multocida 0019 was used to produce specific antibody against P. multocida B:2. The antiboy was then used to sensitise latex particles. Latex agglutination test have been used to screen some P. multocida field isolates and this test have been proven to be specific, simple and easy to be used in detecting P. multocida B:2. The specificity is due to antibodies recognising LPS or LPS protein complexes. Sensitised latex was stable at 4° C for at least12 months. This test should be used as an aid to diagnosis and employed principally to confirm and support clinical and post mortem findings of HS.

    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.

    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) 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.

    Chronic Myeloid Leukaemia (CML) causes retinopathy manifesting as venous dilation and tortuosity, perivascular sheathing, retinal haemorrhages, microaneurysms, cotton-wool spots and optic nerve infiltration. Retina is the most commonly involved intraocular structure in CML. However, retinal involvement is a rare form of presentation of CML and few cases have been reported. We report a case of CML presenting as unilateral sudden visual loss. Fundus showed multiple white centered retinal haemorrhages in both eyes with unilateral macular oedema. Blood work-up showed raised WBC count, high platelet count and low Haemoglobin. Cytological analysis of bone marrow biopsy confirmed Philadelphia chromosome. After a course of Imatinib, visual acuity improved and haemorrhages resolved with normalization of macular thickness. In our case, patient presented early, leading to early detection producing better visual prognosis. This highlights the importance of detailed hematological work up in patients with retinal involvement to rule out leukaemic retinopathy.

    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.

    Whinnery, J E

    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)

    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.

    2015-05-01

    We report the case of a 43-year-old man with a middle cranial fossa arachnoid cyst who presented post trauma with neurological symptoms. The initial CT scan of the brain did not detect acute changes in the arachnoid cyst but subsequent imaging revealed abnormalities which progressed over time. Arachnoid cysts are usually a benign and incidental finding. Rare complications such as intracystic haemorrhage and subdural haemorrhage can occur. It is important to be aware of these complications so that patients with arachnoid cysts are appropriately investigated when presenting with neurological symptoms.

  18. Practical management for urgent reversal of oral anticoagulation in patients with acute intracerebral haemorrhage

    Directory of Open Access Journals (Sweden)

    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.

    2004-06-01

    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.

    The term cortical spreading depolarization (CSD) describes a wave of mass neuronal depolarization associated with net influx of cations and water. Clusters of prolonged CSDs were measured time-locked to progressive ischaemic damage in human cortex. CSD induces tone alterations in resistance vessels, causing either transient hyperperfusion (physiological haemodynamic response) in healthy tissue; or hypoperfusion [inverse haemodynamic response = cortical spreading ischaemia (CSI)] in tissue at risk for progressive damage, which has so far only been shown experimentally. Here, we performed a prospective, multicentre study in 13 patients with aneurysmal subarachnoid haemorrhage, using novel subdural opto-electrode technology for simultaneous laser-Doppler flowmetry (LDF) and direct current-electrocorticography, combined with measurements of tissue partial pressure of oxygen (ptiO(2)). Regional cerebral blood flow and electrocorticography were simultaneously recorded in 417 CSDs. Isolated CSDs occurred in 12 patients and were associated with either physiological, absent or inverse haemodynamic responses. Whereas the physiological haemodynamic response caused tissue hyperoxia, the inverse response led to tissue hypoxia. Clusters of prolonged CSDs were measured in five patients in close proximity to structural brain damage as assessed by neuroimaging. Clusters were associated with CSD-induced spreading hypoperfusions, which were significantly longer in duration (up to 144 min) than those of isolated CSDs. Thus, oxygen depletion caused by the inverse haemodynamic response may contribute to the establishment of clusters of prolonged CSDs and lesion progression. Combined electrocorticography and perfusion monitoring also revealed a characteristic vascular signature that might be used for non-invasive detection of CSD. Low-frequency vascular fluctuations (LF-VF) (f fashion similar to that shown previously for spreading depressions of high

  3. Interleukin-1 receptor antagonist is beneficial after subarachnoid haemorrhage in rat by blocking haem-driven inflammatory pathology

    Directory of Open Access Journals (Sweden)

    Andrew D. Greenhalgh

    2012-11-01

    Subarachnoid haemorrhage (SAH is a major contributor to the burden of stroke on society. Treatment options are limited and animal models of SAH do not always mimic key pathophysiological hallmarks of the disease, thus hindering development of new therapeutics. Inflammation is strongly associated with brain injury after SAH in animals and patients, and inhibition of the pro-inflammatory cytokine interleukin-1 (IL-1 represents a possible therapeutic target. Here we report that a rupture of the middle cerebral artery in the rat produces heterogeneous infarct patterns similar to those observed in human SAH. Administration of the IL-1 receptor antagonist (IL-1Ra reduced blood-brain barrier breakdown, and the extent of breakdown correlated with brain injury. After SAH, haem oxygenase-1 (HO-1 was strongly expressed around the bleed site and in the cortex and striatum, indicating the presence of free haem, a breakdown product of haemoglobin. HO-1 expression was also found in the same regions as microglial/macrophage expression of IL-1α. The direct effect of haem on IL-1α expression was confirmed in vitro using organotypic slice culture (OSC. Haem-induced cell death was dependent on IL-1 signalling, with IL-1Ra completely blocking cellular injury. Furthermore, stimulation of mouse primary mixed glial cells with haem induced the release of IL-1α, but not IL-1β. Thus, we suggest that haem, released from lysed red blood cells (RBCs in the subarachnoid space, acts as a danger-associated molecular pattern (DAMP driving IL-1-dependent inflammation. These data provide new insights into inflammation after SAH-induced brain injury and suggest IL-1Ra as a candidate therapeutic for the disease.

    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.

    To evaluate the role and efficacy of pelvic embolisation in the treatment of persistent postpartum haemorrhage after failed arterial ligation and to identify the complications of this procedure in this specific population. The clinical files and angiographic examinations of 12 consecutive women (mean age 32 years) who were treated with pelvic embolisation because of persistent, severe postpartum haemorrhage after failed arterial ligation were reviewed. Angiography revealed that persistent bleeding was due to incomplete arterial ligation (n = 4) or the presence of newly developed anastomotic routes (n = 8). In 11 women, pelvic embolisation stopped the bleeding. Hysterectomy was needed in one woman with retained placenta. Two complications due to pelvic embolisation, including leg ischaemia and transient sciatic nerve ischaemia, were identified, both after internal iliac artery ligation. In women with persistent postpartum haemorrhage after failed arterial ligation, pelvic embolisation is an effective treatment in most cases. However, embolisation of the anastomotic routes that contribute to persistent bleeding may result in ischaemic complications. These potential complications reaffirm that arterial ligation should not be the favoured option for postpartum haemorrhage and that special care must be given during pelvic embolisation after failed arterial ligation.

    2012-02-01

    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.

    2013-04-01

    Marburg virus causes a highly infectious and lethal haemorrhagic fever in primates and may be exploited as a potential biothreat pathogen. To combat the infection and threat of Marburg haemorrhagic fever, there is a need to develop and license appropriate medical countermeasures. To determine whether the common marmoset (Callithrix jacchus) would be an appropriate model to assess therapies against Marburg haemorrhagic fever, initial susceptibility, lethality and pathogenesis studies were performed. Low doses of virus, between 4 and 28 TCID50 , were sufficient to cause a lethal, reproducible infection. Animals became febrile between days 5 and 6, maintaining a high fever before succumbing to disease between 8 and 11 days postchallenge. Typical signs of Marburg virus infection were observed including haemorrhaging and a transient rash. In pathogenesis studies, virus was isolated from the animals' lungs from day 3 postchallenge and from the liver, spleen and blood from day 5 postchallenge. Early signs of histopathology were apparent in the kidney and liver from day 3. The most striking features were observed in animals exhibiting severe clinical signs, which included high viral titres in all organs, with the highest levels in the blood, increased levels in liver function enzymes and blood clotting times, decreased levels in platelets, multifocal moderate-to-severe hepatitis and perivascular oedema.

    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.

    Cerebral angiography is an invasive procedure associated with a small, but definite risk of neurological morbidity. In this study we sought to establish the nature and rate of complications at our institution among a large prospective cohort of consecutive patients. Also, the data were analysed in an attempt to identify risk factors for complications associated with catheter angiography. Data were prospectively collected for a consecutive cohort of patients undergoing diagnostic cerebral angiography between January 2001 and May 2006. A total of 2,924 diagnostic cerebral angiography procedures were performed during this period. The following data were recorded for each procedure: date of procedure, patient age and sex, clinical indication, referring specialty, referral status (routine/emergency), operator, angiographic findings, and the nature of any clinical complication or asymptomatic adverse event (arterial dissection). Clinical complications occurred in 23 (0.79%) of the angiographic procedures: 12 (0.41%) significant puncture-site haematomas, 10 (0.34%) transient neurological events, and 1 nonfatal reaction to contrast agent. There were no permanent neurological complications. Asymptomatic technical complications occurred in 13 (0.44%) of the angiographic procedures: 3 groin dissections and 10 dissections of the cervical vessels. No patient with a neck dissection suffered an immediate or delayed stroke. Emergency procedures (P = 0.0004) and angiography procedures performed for intracerebral haemorrhage (P = 0.02) and subarachnoid haemorrhage (P = 0.04) were associated with an increased risk of complications. Neurological complications following cerebral angiography are rare (0.34%), but must be minimized by careful case selection and the prudent use of alternative noninvasive angiographic techniques, particularly in the acute setting. The low complication rate in this series was largely due to the favourable case mix. (orig.)

    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.

    1. Cerebral arteries and veins were demonstrated by multiplane computed cerebral angiotomography (combination of axial, modified coronal, half axial (Towne), and semisagittal planes). The vessels which were demonstrated by various planes were as follows: Axial plane: Willis ring, middle cerebral arteries (horizontal and insular portions), anterior cerebral arteries (Horizontal and ascending portions), posterior cerebral arteries, basal vein of Rosenthal, internal cerebral veins (and the subependymal veins which join the ICV), and vein of Galen. Coronal plane: intermal carotid arteries (supraclinoid portion), anterior cerebral arteries (horizontal portion), middle cerebral arteries (horizontal and insular portions), lenticulostriate arteries, basal vein of Rosenthal (and the subependymal veins which join this vessel), internal cerebral veins, and vein of Galen. Half axial plane (Towne projection): basilar artery, vertebral arteries, posterior cerebral arteries, superior cerebellar arteries, middle cerebral arteries (horizontal portion), and anterior cerebral arteries (horizontal and ascending portions). Semisagittal plane: internal carotid artery (supraclinoid portion), posterior communicating artery, posterior carebral artery, superior cerebellar artery, internal cerebral vein, basal vein of Rosenthal, vein of Galen, and straight shinus. 2. A detailed knowledge of normal cerebrovascular structures acquired by computed tomography (CT) is essential in detecting and more precisely localizing lesions such as cerebrovascular disease, neoplasm or abscess, in differentiating these lesions from the normal contrast-enhanced structures, and in understanding the spatial relationship between the mass lesion and the neighboring vessels. In addition, it will be possible to discover such asymptomatic cerebrovascular diseases as non-ruptured aneurysms, arteriovenous malformations, and Moyamoya disease by means of computed cerebral angiotomography.

    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.

    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.

    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.)

  7. 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.

    Rehman, Abdul

    2014-08-01

    Acute primary haemorrhagic omental torsion is an atypical and deceptive cause of acute abdomen that could closely mimic a myriad of intra-abdominal catastrophes, especially perforated appendicitis. The author reports a 30 years man who had presented with gradually worsening right-sided abdominal pain of 2 days duration. Laboratory work-up and abdominal radiographs were inconclusive. Abdominal sonography detected presence of free fluid in the pelvic cul-de-sac. Based on clinical and sonographic findings, presumptive diagnosis of perforated appendicitis was made and the patient was explored through extended Rockey-Davis incision. About 500 - 700 ml of dark-coloured blood (haemoperitoneum) was present in the peritoneal cavity and the pelvis secondary to acute haemorrhagic omental torsion. The appendix was grossly normal. Omentectomy and prophylactic appendicectomy resulted in uneventful recovery of the patient. Acute primary omental torsion is an uncommon pathology that must be kept in mind during differential diagnosis of acute abdomen, especially acute or perforated appendicitis.

    Full Text Available A 9-year-old, intact male, Brie’s shepherd dog, with a 10-day history of depression and tachypnoea developed signs of central neurological dysfunction. 16 Multislice Computed Tomography (CT pre- and postcontrast studies of the brain revealed a single intra-axial homogeneous well-circumscribed hyperattenuating (+/− 62 HU and noncontrast-enhancing area, 5 mm in diameter, in the caudal part of the mesencephalon. This finding was highly suggestive of a haemorrhagic event. A pituitary-dependent hyperadrenocorticism (PDH was identified and is considered likely to be the underlying cause. A repeat CT scan examination, 2 months later, showed almost complete resolution of the brain lesion. The present case describes a solitary 5 mm diameter lesion: the result of intracranial haemorrhage in a dog with presumed PDH.

    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.

    Intractable haemorrhage from the bladder wall during transurethral resection of bladder tumour is uncommon but potentially catastrophic. Internal iliac artery embolisation is a minimally invasive technique, which is now widely practised to stop bleeding from branches of these arteries in situations including pelvic malignancy, obstetric and gynaecological emergencies and trauma. We report its successful use peri-operatively, in an unfit, elderly patient with uncontrolled bleeding.

  19. Neurosarcoidosis-related intracranial haemorrhage: three new cases and a systematic review of the literature.

    LENUS (Irish Health Repository)

    O'Dwyer, J P

    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.

    Conclusions: Uterine artery embolization is an effective and reliable method for control of haemorrhage in pseudoaneurysm. One should have doubt about pseudoaneurysm in cases of secondary PPH where the bleeding is recurrent and cause not acertainable and to be referred in time where the facility of uterine artery embolization is available.

    Full Text Available This study investigates the role of cervical sympathectomy in the prevention of acute vasospasm induced by meningeal haemorrhage in rabbits. Sixteen adult English Norfolk rabbits were divided into 2 experimental groups: bilateral cervical sympathectomy of the superior sympathetic ganglion (SSSG, n=8, and bilateral SSSG and sympathectomy of the inferior sympathetic ganglion (SISG, n=8. Other 24 animals were used as controls. Basilar artery diameter was evaluated by angiography. SSSG protected the animals against developing cerebral vasospasm; SSSG associated with SISG did not increase this effect.Este estudo investiga o papel da simpatectomia cervical na prevenção do vasoespasmo agudo induzido por hemorragia meníngea em coelhos.

    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

    Full Text Available Background. Duodenal gastrointestinal stromal tumours (GISTs are an uncommon malignancy of the gastrointestinal (GI tract. We present a case of life-threatening haemorrhage caused by a large ulcerating duodenal GIST arising from the third part of the duodenum managed by a limited duodenal wedge resection. Case Presentation. A 61-year-old patient presented with acute life-threatening gastrointestinal bleeding. After oesophagogastroduodenoscopy failed to demonstrate the source of bleeding, a 5 cm ulcerating exophytic mass originating from the third part of the duodenum was identified at laparotomy. A successful limited wedge resection of the tumour mass was performed. Histopathology subsequently confirmed a duodenal GIST. The patient remained well at 12-month followup with no evidence of local recurrence or metastatic spread. Conclusion. Duodenal GISTs can present with life-threatening upper GI haemorrhage. In the context of acute haemorrhage, even relatively large duodenal GISTs can be treated by limited wedge resection. This is a preferable alternative to duodenopancreatectomy with lower morbidity and mortality but comparable oncological outcome.

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.

    Full Text Available Abstract Information on the replication of viral haemorrhagic fever viruses is not readily available and has never been analysed in a comparative approach. Here, we compared the cell culture growth characteristics of haemorrhagic fever viruses (HFV, of the Arenaviridae, Filoviridae, Bunyaviridae, and Flavivridae virus families by performing quantitative analysis of cell culture supernatants by (i electron microscopy for the quantification of virus particles, (ii quantitative real time PCR for the quantification of genomes, and (iii determination of focus forming units by coating fluorescent antibodies to infected cell monolayers for the quantification of virus infectivity. The comparative analysis revealed that filovirus and RVFV replication results in a surplus of genomes but varying degrees of packaging efficiency and infectious particles. More efficient replication and packaging was observed for Lassa virus, and Dengue virus resulting in a better yield of infectious particles while, YFV turned out to be most efficient with only 4 particles inducing one FFU. For Crimean-Congo haemorrhagic fever virus (CCHFV a surplus of empty shells was observed with only one in 24 particles equipped with a genome. The complete particles turned out to be extraordinarily infectious.

    The advent of multi-section computed tomography (CT) technology allows the non-invasive assessment of the arterial tree. Using current software, it is now possible to produce high-quality, angiographic-like images that can be used to plan and guide therapeutic procedures. One such clinical situation is the assessment of patients with acute gastrointestinal (GI) haemorrhage. Multi-section CT has a number of advantages over conventional angiography in this situation. The simplicity and non-invasive nature of the technique compared with conventional angiography make CT angiography possible in situations where conventional angiography is not available. Movement artefact from respiration and peristalsis is a common problem in the interpretation of conventional angiography; this is essentially abolished with rapid acquisition times and the use of multi-planar images to remove overlying bowel loops. Cross-sectional imaging with the ability for multi-planar reconstruction allows the accurate anatomical localization of the bleeding site, as well as an assessment of the underlying pathology: this can be used to plan therapy (embolization or surgery). The aim of this paper is to review the current use of CT in the investigation of patients with GI haemorrhage, illustrated with images from our Institution. For patients in whom GI endoscopy has failed to establish a diagnosis, we propose multi-section CT angiography as the initial imaging investigation in acute GI haemorrhage.

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is a small vessel vasculitis that affects mainly the skin, joints, gastrointestinal tract and kidneys. The central nervous system is also occasionally affected, although the majority of patients experience only mild symptoms such as headaches and behavioural changes. Intracerebral haemorrhage is a rare complication of Henoch-Schönlein purpura that so far has mainly been described in children and young adolescence. Case presentation We describe a 42-year-old man with Henoch-Schönlein purpura who developed an acute intracerebral haemorrhage that coincided with a reactivation of his vasculitis and the development of renal failure following discontinuation of steroids. In this patient, both the Henoch-Schönlein purpura and his neurological symptoms were successfully treated with intravenous cyclophosphamide and methylprednisolone, followed by a short course of oral cyclophosphamide and long-term oral prednisolone. His renal function also recovered sufficiently not to require renal replacement therapy. Conclusion The management of Henoch-Schönlein nephritis remains unclear, especially in the presence of severe complications such as intracerebral haemorrhage. We describe a successful outcome in such a patient.

    Objectives Sublingual microcirculatory monitoring for traumatic haemorrhagic shock (THS) may predict clinical outcomes better than traditional blood pressure and cardiac output, but is not usually performed until the patient reaches the intensive care unit (ICU), missing earlier data of potential importance. This pilot study assessed for the first time the feasibility and safety of sublingual video-microscopy for THS in the emergency department (ED), and whether it yields useable data for analysis. Setting A safety and feasibility assessment was undertaken as part of the prospective observational MICROSHOCK study; sublingual video-microscopy was performed at the UK-led Role 3 medical facility at Camp Bastion, Afghanistan, and in the ED in 3 UK Major Trauma Centres. Participants There were 15 casualties (2 military, 13 civilian) who presented with traumatic haemorrhagic shock with a median injury severity score of 26. The median age was 41; the majority (n=12) were male. The most common injury mechanism was road traffic accident. Primary and secondary outcome measures Safety and feasibility were the primary outcomes, as measured by lack of adverse events or clinical interruptions, and successful acquisition and storage of data. The secondary outcome was the quality of acquired video clips according to validated criteria, in order to determine whether useful data could be obtained in this emergency context. Results Video-microscopy was successfully performed and stored for analysis for all patients, yielding 161 video clips. There were no adverse events or episodes where clinical management was affected or interrupted. There were 104 (64.6%) video clips from 14 patients of sufficient quality for analysis. Conclusions Early sublingual microcirculatory monitoring in the ED for patients with THS is safe and feasible, even in a deployed military setting, and yields videos of satisfactory quality in a high proportion of cases.

    Cerebral Amyloidal Angiopathy (CAA), which occurs sporadically in most cases but can also occur hereditarily, belongs to the group amyloidoses and is characterized by the deposition and accumulation of beta-amyloid (Aβ) in smaller arterial vessels of the brain. The deposition of Aβ leads to degenerative changes in the cerebral vessel system (thickening of the vessel wall, microaneurysm, constriction of vascular lumen, dissection), which favour the development of the clinical symptomatology most often associated with CAA. Besides haemorrhages, cerebral ischaemia, transient neurological symptoms, leukoencephalopathy as well as cognitive decline and even dementia may appear in connection with CAA. A definite diagnosis of CAA can only be made on the basis of a pathological assessment, even though diagnostic findings of cerebral neuroimaging and clinical symptoms allow the diagnosis of a probable CAA. At present, no causal therapy options are available. Although CAA is placed within the range of neurological illnesses, psychiatric symptoms such as cognitive impairment, personality change or behavioural problems as well as depression are plausible clinical manifestations of CAA and may even dominate the clinical picture. Apart from epidemiological, pathogenetical, clinical and diagnostical aspects, possible psychiatric implications of CAA are discussed in the review article.

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.

    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.

    Cerebral ischemia induces excess release of glutamate and an increase in the intracellular Ca2+ concentration, which provoke catastrophic enzymatic processes leading to irreversible neuronal injury. Histamine plays the role of neurotransmitter in the central nervous system, and histaminergic fibers are widely distributed in the brain. In cerebral ischemia, release of histamine from nerve endings has been shown to be enhanced by facilitation of its activity. An inhibition of the histaminergic activity in ischemia aggravates the histologic outcome. In contrast, intracerebroventricular administration of histamine improves the aggravation, whereas blockade of histamine H2 receptors aggravates ischemic injury. Furthermore, H2 blockade enhances ischemic release of glutamate and dopamine. These findings suggest that central histamine provides beneficial effects against ischemic neuronal damage by suppressing release of excitatory neurotransmitters. However, histaminergic H2 action facilitates the permeability of the blood-brain barrier and shows deleterious effects on cerebral edema.

    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...

  1. Carbon dioxide induced changes in cerebral blood flow and flow velocity: role of cerebrovascular resistance and effective cerebral perfusion pressure.

    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.

  2. A critical review of anaesthetised animal models and alternatives for military research, testing and training, with a focus on blast damage, haemorrhage and resuscitation.

    2013-11-01

    Military research, testing, and surgical and resuscitation training, are aimed at mitigating the consequences of warfare and terrorism to armed forces and civilians. Traumatisation and tissue damage due to explosions, and acute loss of blood due to haemorrhage, remain crucial, potentially preventable, causes of battlefield casualties and mortalities. There is also the additional threat from inhalation of chemical and aerosolised biological weapons. The use of anaesthetised animal models, and their respective replacement alternatives, for military purposes -- particularly for blast injury, haemorrhaging and resuscitation training -- is critically reviewed. Scientific problems with the animal models include the use of crude, uncontrolled and non-standardised methods for traumatisation, an inability to model all key trauma mechanisms, and complex modulating effects of general anaesthesia on target organ physiology. Such effects depend on the anaesthetic and influence the cardiovascular system, respiration, breathing, cerebral haemodynamics, neuroprotection, and the integrity of the blood-brain barrier. Some anaesthetics also bind to the NMDA brain receptor with possible differential consequences in control and anaesthetised animals. There is also some evidence for gender-specific effects. Despite the fact that these issues are widely known, there is little published information on their potential, at best, to complicate data interpretation and, at worst, to invalidate animal models. There is also a paucity of detail on the anaesthesiology used in studies, and this can hinder correct data evaluation. Welfare issues relate mainly to the possibility of acute pain as a side-effect of traumatisation in recovered animals. Moreover, there is the increased potential for animals to suffer when anaesthesia is temporary, and the procedures invasive. These dilemmas can be addressed, however, as a diverse range of replacement approaches exist, including computer and mathematical

    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.

    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.

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.

    Lipomas of the colon are benign tumors that rarely occur. Their size ranges from 2 mm to several cm. They are usually asymptomatic but occasionally they present with clinical manifestations depending on tumor size, localization and complications, which often lead to diagnostic difficulty. A 40-year-old man presented with massive rectal haemorrhage. During colonoscopy a giant polyp of over 50 mm in its bigger diameter, with a thick stalk of 2 cm, located in the transverse colon, was revealed. Endoscopic resection was performed with success. Histologic examination demonstrated a giant lipoma. In this report discussion over endoscopic resection of colonic lipomas mimicking neoplasms is also performed.

    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...... these data with the geographical coordinates of fish farms to identify clusters of high disease prevalence and other risk factors. Our analyses revealed a statistically significant cluster in the southwestern part of the country, which persisted throughout the study period. Being situated within...

    Farming of rainbow trout (Oncorhynchus mykiss) in Europe is hampered by unacceptably heavy losses due to the severe infectious disease viral haemorrhagic septicaemia (VHS). Strain-dependent variation of VHS resistance exists. A long-term breeding programme to increase VHS resistance in rainbow...... trout has been started in Denmark. This programme will be based on experimental VHS challenge of the parental fish (n = 84) as well as their normal and gynogenetic offspring (16 fullsib F1 groups).

    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.

    In general, viral haemorrhagic septicaemia virus (VHSV) isolates from marine fish species in European waters (genotypes GIb, GII and GIII) are non- to low virulent in rainbow trout. However, a VHSV isolation was made in 2007 from a disease outbreak in sea farmed rainbow trout in Norway. The isolate, named NO-2007-50-385, was demonstrated to belong to GIII. This isolate has attracted attention to assess which of the viral genome/proteins might be associated with the virulence in rainbow trout....

    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.

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.

    The report demonstrates that the induction of apoptosis in peripheral blood granulocytes and lymphocytes of rabbits infected with three non-haemagglutinating RHDV strains (English Rainham, German Frankfurt, and Spanish Asturias) is a crucial determinant of the pathogenesis of rabbit haemorrhagic disease. Apoptosis was measured by flow cytometric detection of caspase activity. These studies demonstrated that the investigated RHDV (rabbit haemorrhagic disease virus) viral strains affected leukocyte apoptosis to varying degrees. Enhanced leukocyte apoptosis was detected between 4 and 36 h after infection and was more pronounced in lymphocytes than in granulocytes. The data presented here thus provide a preliminary understanding of the kinetics of apoptosis in leukocytes of rabbits infected with RHDV.

    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.

    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.)

  2. A case report of haemorrhagic-aneurismal bone cyst of the mandible

    Full Text Available Haemorrhagic-aneurismal bone cysts (HABCs are quite rare, benign, non-neoplastic, expansive, and vascular locally destructive lesions. They are generally considered sequelae of an earlier trauma causing an overflow of blood into the bone. HABCs are classified as pseudocysts and they should be differentiated from true cysts because their treatment is different. Since few of these cysts involve subjective symptoms, most are discovered accidentally during radiography, while a sure diagnosis is likely to be obtained only during surgery, on discovery of a non-epithelialised cavity. Here, we report a typical case of a haemorrhagic-mandibular cyst in a 13-year-old girl, which was treated by opening the cavity and scraping its walls following diagnostic arteriography and post-operative transcutaneous intralesional embolization. No further complications were recorded in the post-operative period, although the convalescence lasted for a time longer than expected, because of anemia. No further surgery was performed. She has been disease-free for two years. Evaluation of intralesional blood flow is important for HABCs because of the hemorrhagic risk in surgery. Embolization seems to be a useful procedure in the treatment of HABCs and could be tried as the treatment modality in the standard protocol for the treatment of HABCs.

    The hyperintense acute reperfusion marker (HARM) has been described as a predictor for haemorrhagic transformation (HT) in acute ischaemic stroke. We hypothesised that this phenomenon is not present in the elderly. It was possible to assess 47/84 consecutive patients aged 80 and over with diagnosed ischaemic stroke or transient ischaemic attack (TIA). MRI was performed within 24 h of onset of symptoms with follow-up MRI within a further 48 h. Of 47 included patients, 19 showed HARM; it was only seen on follow-up examination. Ten of the 47 patients underwent thrombolysis with recombinant tissue plasminogen activator (rt-PA); 4 of them showed HARM, and 1 of those showed HT. HARM was found in three out of eight patients with haemorrhagic transformation on baseline and/or follow-up MRI. We did not observe an association between HARM and early HT either in the whole group or in the patients who received thrombolysis. HARM was not associated with HT in the elderly after ischaemic stroke, independent of treatment. While it may indicate dysfunction of the blood-brain barrier (BBB), it does not necessarily amount to HT. (orig.)

    The pathogenicity of RHDV (rabbit haemorrhagic disease virus) is mainly associated with its affinity to blood vessels, with causing disseminated intravascular coagulations (DIC), and with the stimulation of the host immune system. Moreover, there are implications suggesting that apoptosis may be a pivotal process in understanding the basis of viral haemorrhagic disease in rabbits - a serious infectious disease causing mortality to wild and domestic rabbits. The aim of this study is to evaluate, by means of flow cytometry, the dynamics of apoptosis in peripheral blood granulocytes and lymphocytes in rabbits experimentally infected with seven different strains of RHDV and so-called antigenic variants of RHDV denominated as RHDVa, i.e.: Hungarian 24V/89, 1447V/96, 72V/2003; Austrian 01-04, 237/04, V-412 and French 05-01. The results showed that all of the RHDV and RHDVa strains cause an increase in the number of apoptotic cells throughout the infection, which might indicate the need for further analysis of the importance of this process.

    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.

    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.)

    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.

  8. 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.

    Historical records describe a disease in North America that clinically resembled dengue haemorrhagic fever during the latter part of the slave-trading period. However, the dengue epidemic that occurred in Cuba in 1981 was the first laboratory-confirmed and clinically diagnosed outbreak of dengue haemorrhagic fever in the Americas. At that time, the presumed source of the dengue type 2 strain isolated during this epidemic was considered controversial, partly because of the limited sequence data and partly because the origin of the virus appeared to be southern Asia. Here, we present a molecular characterisation at the whole-genome level of the original strains isolated at different time points during the epidemic. Phylogenetic trees constructed using Bayesian methods indicated that 1981 Cuban strains group within the Asian 2 genotype. In addition, the study revealed that viral evolution occurred during the epidemic - a fact that could be related to the increasing severity from month to month. Moreover, the Cuban strains exhibited particular amino acid substitutions that differentiate them from the New Guinea C prototype strain as well as from dengue type 2 strains isolated globally.

    Intracerebral haemorrhage (ICH) is associated with significant early mortality (up to 50% at 30 days) and long-term morbidity (with permanent neurological deficits in 75-80% of patients) and represents a serious health issue worldwide. The past decade has seen a dramatic increase in clinical research on ICH diagnosis and treatment that has led to revision of the guidelines for the diagnosis and management of ICH from the American Heart Association and American Stroke Association in 2013. This systematic review reports recent clinical evidence (original studies published between September 2013 and July 2015) related to neurocritical care and intensive care unit management of patients with ICH. All but one publication included in this review report original studies related to managment of patients with intracerebral or subarachnoid haemorrhage. These include insights on risk stratification and neurocritical care or intensive care unit treatment, management of haemodynamic variables and mechanical ventilation (goal-directed fluid therapy, advanced haemodynamic monitoring, and avoidance of hyperoxia and hyperventilation), and pharmacological neuroprotection.

    Bats can carry important zoonotic pathogens. Here we use a combination of next-generation sequencing and classical virus isolation methods to identify novel nairoviruses from bats captured from a cave in Zambia. This nairovirus infection is highly prevalent among giant leaf-nosed bats, Hipposideros gigas (detected in samples from 16 individuals out of 38). Whole-genome analysis of three viral isolates (11SB17, 11SB19 and 11SB23) reveals a typical bunyavirus tri-segmented genome. The strains form a single phylogenetic clade that is divergent from other known nairoviruses, and are hereafter designated as Leopards Hill virus (LPHV). When i.p. injected into mice, the 11SB17 strain causes only slight body weight loss, whereas 11SB23 produces acute and lethal disease closely resembling that observed with Crimean-Congo Haemorrhagic Fever virus in humans. We believe that our LPHV mouse model will be useful for research on the pathogenesis of nairoviral haemorrhagic disease.

    This article presents a systematic review of the current biomedical literature surrounding the aetiopathogenesis and histopathological features of bone marrow oedema, reactive bone change and haemorrhage. Bone marrow oedema is generally demonstrated as a non-specific finding on magnetic resonance imaging in association with infections, tumours and avascular necrosis. When it occurs in isolation as a primary event not triggered by any obvious bony pathology in the clinical setting of debilitating joint pain, it constitutes the 'bone marrow oedema syndrome'. Although the latter diagnosis is based on magnetic resonance (MR) imaging, showing the lesion as areas of signal hyperintensity within the marrow, recent radiology-histology correlational studies have shown variably interstitial marrow oedema, necrosis, fibrosis and trabecular bone abnormalities. In light of these facts, the use of the term bone marrow oedema syndrome in a radiological context might be considered questionable, but histopathological techniques are not sensitive in detecting increased extracellular fluid. Reactive bone changes may be focal or diffuse and usually amount to increased bone formation. Bone marrow haemorrhage, due to trauma, results in bone bruising, a condition in which the size of the bruise and associated osteochondral injury determines the outcome, although the natural history of these lesions is still being researched.

    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.

    Antarctic tourism on board cruise ships has expanded since the 1990s, essentially in the Antarctic Peninsula. Due to remoteness, medical cases may evolve into life threatening conditions as emergency medical evacuations are challenging. We discuss the case of a young crew member who suddenly fainted with an epigastric pain and abundant rectal bleeding while on board a cruise ship heading to the Deception Island (62°57.6 South, 60°29.5 West), 44 h away from Ushuaia by sea. A medical evacuation was necessary to save the patient whose haemoglobin level rapidly decreased from 11 g/dL to 8.7 g/dL over an 8 h period due to uncontrolled gastrointestinal bleeding. Following discussions between the French, Chilean and Argentinean Medical Top Side Support and Maritime Rescue Authorities and despite poor weather conditions, an emergency medical evacuation by air to Chile was made possible. The evacuation, which was 2 days shorter compared to an evacuation by sea, allowed the patient to reach a hospital facility in time to save his life whereas he decompensated in haemorrhagic shock. As passengers on cruise ships are typically elderly and often following anticoagulant therapies, the risk of bleeding is most important. Facing a gastric haemorrhage, a transfusion is often required. In remote areas, transfusion of fresh whole blood to stabilize a critical patient until he reaches a hospital must be considered.

    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.

    After cancer and cardio-vascular disease, stroke is the third greatest cause of death worldwide. Given the limitations of the current imaging technologies used for stroke diagnosis, the need for portable non-invasive and less expensive diagnostic tools is crucial. Previous studies have suggested that electrical bioimpedance (EBI) measurements from the head might contain useful clinical information related to changes produced in the cerebral tissue after the onset of stroke. In this study, we recorded 720 EBI Spectroscopy (EBIS) measurements from two different head regions of 18 hemispheres of nine subjects. Three of these subjects had suffered a unilateral haemorrhagic stroke. A number of features based on structural and intrinsic frequency-dependent properties of the cerebral tissue were extracted. These features were then fed into a classification tree. The results show that a full classification of damaged and undamaged cerebral tissue was achieved after three hierarchical classification steps. Lastly, the performance of the classification tree was assessed using Leave-One-Out Cross Validation (LOO-CV). Despite the fact that the results of this study are limited to a small database, and the observations obtained must be verified further with a larger cohort of patients, these findings confirm that EBI measurements contain useful information for   assessing on the health of brain tissue after stroke and supports the hypothesis that classification features based on Cole parameters, spectral information and the geometry of EBIS measurements are useful to differentiate between healthy and stroke damaged brain tissue.

    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.

    Full Text Available Increased attenuation of the basal cisterns and subarachnoid spaces on CT scans is a characteristic finding of acute subarachnoid hemorrhage. CT mimics of SAH have been called pseudo-SAH. Our case is presented to underline the differentiation of two diagnosis. A 63-year-old man was admitted to the emergency room with right-sided hemiparesis and aphasia. He had middle cerebral artery enfarct on his CT. A week after his hospitalisation his neurological examination was deteriorated. A plain CT-scan of brain was consistent with sub-arachnoid hemorrhage. His antiagregant therapy was ended and anti edema therapy started. Urgent neurosurgical consultation was sought & surgery was not planned. Brain death was the finding in his CT angiography. So the CT-scan findings turned out to be `pseudo sub-arachnoid haemorrhage’.Pseudo sub-arachnoid haemorrhage is a rare CT scan finding that has been reported in different cerebral disease with cerebral edema. MR imaging studies, CSF examination by lumbar puncture and the criterias proposed by Yazawa can be useful to make the diagnosis. The aim is the unnecessary termination of antiagregant and anticoagulant therapy.

    Single-photon emission computed tomography (SPECT) can provide three-dimensional functional images of the brain following the injection of one of a series of radiopharmaceuticals that crosses the blood-brain barrier and distributes according to cerebral perfusion, neurotransmitter, or cell density. Applications include differentiating between the dementias, evaluating cerebrovascular disease, preoperative localization of epileptogenic foci, diagnosing movement disorders, and evaluation of intracerebral tumours, while also proving a useful research tool. Unlike positronemission tomography (PET), SPECT imaging is widely available and can be performed in any department that has access to a rotating gamma camera. The purpose of this review is to demonstrate the utility of cerebral SPECT and increase awareness of its role in the investigation of neurological and psychiatric disorders.

    Computerized tomography, carotid angiograms, and arteriography were used to diagnose several cases of cerebral hemorrhage following the use of phenylpropanolamine. 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.

    Full Text Available Traumatic brain injury (TBI is on the rise, especially in today′s fast-paced world. TBI requires not only neurosurgical expertise but also neurointensivist involvement for a better outcome. Disturbances of sodium balance are common in patients with brain injury, as the central nervous system plays a major role in sodium regulation. Hyponatraemia, defined as serum sodium <135 meq/L is commonly seen and is especially deleterious as it can contribute to cerebral oedema in these patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH, is the most well-known cause of hyponatraemia in this subset of patients. Cerebral Salt Wasting Syndrome (CSWS, leading to renal sodium loss is an important cause of hyponatraemia in patients with TBI. Although incompletely studied, decreased renal sympathetic responses and cerebral natriuretic factors play a role in the pathogenesis of CSWS. Maintaining a positive sodium balance and adequate hydration can help in the treatment. It is important to differentiate between SIADH and CSWS when trying to ascertain a case for patients with acute brain injury, as the treatment of the two are diametrically opposite.

  2. Cerebral oxygenation and hyperthermia

    Anthony Richard Bain

    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.

    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.

    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.)

    Advancements in molecular biology have led to a greater understanding of the individual proteins responsible for generating cerebral edema. In large part, the study of cerebral edema is the study of maladaptive ion transport. Following acute CNS injury, cells of the neurovascular unit, particularly brain endothelial cells and astrocytes, undergo a program of pre- and post-transcriptional changes in the activity of ion channels and transporters. These changes can result in maladaptive ion transport and the generation of abnormal osmotic forces that, ultimately, manifest as cerebral edema. This review discusses past models and current knowledge regarding the molecular and cellular pathophysiology of cerebral edema.

    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.

  8. Comparative Genomic Analysis of Asian Haemorrhagic Septicaemia-Associated Strains of Pasteurella multocida Identifies More than 90 Haemorrhagic Septicaemia-Specific Genes.

    Full Text Available Pasteurella multocida is the primary causative agent of a range of economically important diseases in animals, including haemorrhagic septicaemia (HS, a rapidly fatal disease of ungulates. There is limited information available on the diversity of P. multocida strains that cause HS. Therefore, we determined draft genome sequences of ten disease-causing isolates and two vaccine strains and compared these genomes using a range of bioinformatic analyses. The draft genomes of the 12 HS strains were between 2,298,035 and 2,410,300 bp in length. Comparison of these genomes with the North American HS strain, M1404, and other available P. multocida genomes (Pm70, 3480, 36950 and HN06 identified a core set of 1,824 genes. A set of 96 genes was present in all HS isolates and vaccine strains examined in this study, but absent from Pm70, 3480, 36950 and HN06. Moreover, 59 genes were shared only by the Asian B:2 strains. In two Pakistani isolates, genes with high similarity to genes in the integrative and conjugative element, ICEPmu1 from strain 36950 were identified along with a range of other antimicrobial resistance genes. Phylogenetic analysis indicated that the HS strains formed clades based on their country of isolation. Future analysis of the 96 genes unique to the HS isolates will aid the identification of HS-specific virulence attributes and facilitate the development of disease-specific diagnostic tests.

    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 found that they mainly included sequence type (ST) 122 (n=50) and rarely ST63 (n=1), ST147 (n=2) and ST162 (n=2) compared to other members of the species isolated from other lesion types and hosts. Single-nucleotide polymorphisms suitable for specific detection of STs associated with HS were detected in 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. The HS-est-RT-PCR developed in the current study seems to more accurately identify isolates of P. multocida associated with HS compared to PCR detection methods previously published.

    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.

    Objective: HIV enters the brain soon after infection causing neuronal damage and microglial/astrocyte dysfunction leading to neuropsychological impairment. We examined the impact of HIV on resting cerebral blood flow (rCBF) within the lenticular nuclei (LN) and visual cortex (VC). Methods: This cross-sectional study used arterial spin labeling MRI (ASL-MRI) to measure rCBF within 33 HIV+ and 26 HIV− subjects. Nonparametric Wilcoxon rank sum test assessed rCBF differences due to HIV serostatus. Classification and regression tree (CART) analysis determined optimal rCBF cutoffs for differentiating HIV serostatus. The effects of neuropsychological impairment and infection duration on rCBF were evaluated. Results: rCBF within the LN and VC were significantly reduced for HIV+ compared to HIV− subjects. A 2-tiered CART approach using either LN rCBF ≤50.09 mL/100 mL/min or LN rCBF >50.09 mL/100 mL/min but VC rCBF ≤37.05 mL/100 mL/min yielded an 88% (29/33) sensitivity and an 88% (23/26) specificity for differentiating by HIV serostatus. HIV+ subjects, including neuropsychologically unimpaired, had reduced rCBF within the LN (p = 0.02) and VC (p = 0.001) compared to HIV− controls. A temporal progression of brain involvement occurred with LN rCBF significantly reduced for both acute/early (<1 year of seroconversion) and chronic HIV-infected subjects, whereas rCBF in the VC was diminished for only chronic HIV-infected subjects. Conclusion: Resting cerebral blood flow (rCBF) using arterial spin labeling MRI has the potential to be a noninvasive neuroimaging biomarker for assessing HIV in the brain. rCBF reductions that occur soon after seroconversion possibly reflect neuronal or vascular injury among HIV+ individuals not yet expressing neuropsychological impairment.

    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.

    Hereditary Haemorrhagic Telangiectasia (HHT) is a muco-cutaneous inherited disease. Symptoms are epistaxis, visceral arterio-venous malformations, multiple muco-cutaneous telangiectasia with the risk of number increasing enlargement, bleeding, and super-infection. The aim of this work is to show the dual Diode Laser efficacy in preventive treatment of Early Lesions (EL < 2mm) and therapeutic treatment of Advanced Lesions (AL < 2mm). 21 patients affected by HHT with 822 muco-cutaneous telangiectatic nodules have been treated in several sessions with local anaesthesia and cooling of treated sites. EL preventive treatment consists of single Laser impulse (fibre 320) in ultrapulsed mode (2 mm single point spot). AL therapeutic treatment consists of repeated Laser impulses in pulsed mode (on 200ms / off 400ms). According to the results, Diode Laser used in pulsed and ultra-pulsed mode is very effective as noninvasive treatment both in early and advanced oral and perioral telangiectasia.

    Rabbit Haemorrhagic Disease (RHD) is caused by a calicivirus (RHDV) that kills 90% of infected adult European rabbits within 3 days. Remarkably, young rabbits are resistant to RHD. We induced immunosuppression in young rabbits by treatment with methylprednisolone acetate (MPA) and challenged the animals with RHDV by intramuscular injection. All of these young rabbits died within 3 days of infection due to fulminant hepatitis, presenting a large number of RHDV-positive dead or apoptotic hepatocytes, and a significant seric increase in cytokines, features that are similar to those of naïve adult rabbits infected by RHDV. We conclude that MPA-induced immunosuppression abrogates the resistance of young rabbits to RHD, indicating that there are differences in the innate immune system between young and adult rabbits that contribute to their distinct resistance/susceptibility to RHDV infection.

    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.

    Full Text Available Haemorrhagic transformation (HT of recently ischaemic brain is a feared complication of thrombolytic therapy that may be caused or compounded by ischaemia-induced activation of matrix metalloproteinases (MMPs. The tetracycline antibiotic minocycline inhibits matrix MMPs and reduces macroscopic HT in rodents with stroke treated with tissue plasminogen activator (tPA. The West Australian Intravenous Minocycline and TPA Stroke Study (WAIMATSS aims to determine the safety and efficacy of adding minocycline to tPA in acute ischaemic stroke. The WAIMATSS is a multicentre, prospective, and randomised pilot study of intravenous minocycline, 200 mg 12 hourly for 5 doses, compared with standard care, in patients with ischaemic stroke treated with intravenous tPA. The primary endpoint is HT diagnosed by brain CT and MRI. Secondary endpoints include clinical outcome measures. Some illustrative cases from the early recruitment phase of this study will be presented, and future perspectives will be discussed.

    A commercial plant extract derived from olive tree leaf (Olea europaea) (LExt) and its major compound, oleuropein (Ole), inhibited the in vitro infectivity of the viral haemorrhagic septicaemia virus (VHSV), a salmonid rhabdovirus. Incubation of virus with LExt or Ole before infection reduced the viral infectivity to 10 and 30%, respectively. Furthermore, LExt drastically decreased VHSV titers and viral protein accumulation (virucidal effect) in a dose dependent manner when added to cell monolayers 36 h post-infection. On the other hand, both the LExt and Ole were able to inhibit cell-to-cell membrane fusion induced by VHSV in uninfected cells, suggesting interactions with viral envelope. Therefore, we propose that O. europaea could be used as a potential source of promising natural antivirals, which have demonstrated to lack impact on health and environment. In addition, Ole could be used to design other related antiviral agents.

    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.

    Myocardial dysfunction occurs frequently during subarachnoid haemorrhage (SAH) and it is often referred to as neurogenic stunned myocardium (NSM). Takotsubo cardiomyopathy (TTC), which can lead to life-threatening acute heart failure, has been considered a possible complication of SAH. Actually, NSM and TTC are believed to share the same pathophysiological mechanisms and are likely a manifestation of the same disease. We report a case of a 64-year-old woman with SAH and cardiogenic shock due to acute left ventricular dysfunction. Echocardiography and ventriculography showed the typical pattern of TTC. Angiography excluded coronary artery disease or coronary spasm. Short-term inotropic support was necessary. Rapid recovery of left ventricular function was observed after 8 days. Acute myocardial dysfunction due to TTC in the setting of SAH may lead to cardiogenic shock which is difficult to treat. Patients with SAH and haemodynamic instability warrant a careful assessment of ventricular function on admission to rule out TTC

    Two cases are reported in which patients known to suffer from chronic liver disorders underwent local anaesthetic dental extractions. In both cases the procedure was followed by severe, intractable post-operative haemorrhage, resistant to local haemostatic measures and requiring hospital admission for intravenous fluid replacement and administration of clotting factors. The importance of not only eliciting details of a patient's medical history, but also of acting appropriately upon that information is emphasised and a recommendation is made that patients with active liver disorders, such as cirrhosis, who require oral surgery procedures should be managed in hospital departments, where access to haematological assessment and appropriate surgical and medical care is readily available. Close liaison with liver physicians and haematologists is recommended.

    Visual functions are often impaired in preterm infants with periventricular haemorrhagic infarction, because of the involvement of the region where the optic radiations are located. In some cases an unexpected sparing of the visual fields has been described, and related to the plasticity of thalamo-cortical afferents that are supposedly able to bypass the lesion when it occurs in the early third trimester of gestation. We systematically reviewed the literature in the field to determine the limits and potentials of this type of reorganization. We found four studies meeting our criteria, from which we extracted case reports on 19 individuals with intraventricular haemorrhagic infarction. Eleven of the 19 did not have visual field defects, five had a bilateral visual field defect, and the remaining three had a unilateral visual field defect. The involvement of the optic radiations was often associated with normal visual fields as only one of the four individuals with damaged optic radiations showed visual field defects. Conversely, the presence of basal ganglia/thalamus involvement apparently prevented such reorganization, as the only two individuals with unilateral field restriction and available magnetic resonance imaging data both showed abnormalities in those structures. Consistent with this, we report on a further individual in which visual field restriction was associated with abnormal tractography on brain magnetic resonance imaging. Overall, this review supports the existence of effective mechanisms of plastic reorganization that allow a rewiring of geniculo-calcarine connections with restoration of full field vision but which are hindered by the involvement of the basal ganglia and thalamus.

    We identified viral haemorrhagic septicaemia virus (VHSV) isolates classified within Genotype Ib which are genetically similar (>99.4% glycoprotein amino acid identity) yet, based on their isolation history, were suspected to differ in virulence in juvenile rainbow trout. The virulence of an isolate recovered in 2000 from a viral haemorrhagic septicaemia disease episode in a marine rainbow trout farm in Sweden (SE-SVA-1033) was evaluated in juvenile rainbow trout via intraperitoneal injection and immersion challenge alongside 3 isolates recovered from wild-caught marine fish (DK-4p37, DK-5e59 and UKMLA98/6HE1) suspected of being of low pathogenicity to trout. Mortality data revealed that isolate SE-SVA-1033 caused VHSV-specific mortality in both intraperitoneal and immersion challenges (75.0 and 15.4%, respectively). The remaining Genotype Ib isolates caused significantly lower mortalities using the same experimental infection routes (<35.0 and <2.0%, respectively). Having identified VHSV isolates with clear differences in their pathogenicity, coding and inter-genic non-coding regions of 2 isolates (SE-SVA-1033 and DK-4p37) were determined and compared in order to identify potential markers responsible for the observed differences in virulence. Only 4 predicted amino acid substitutions were identified across the genome sequenced; these occurred in the N (R46G), G (S113G), NV (L12F) and L (S56A) proteins. These findings form the basis for further studies aimed at determining the biological significance of these mutations and suggest that small changes at the molecular level can cause significant changes in the virulence properties of VHSV isolates.

    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.

  19. Cerebral imaging in pediatrics

    1998-06-01

    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.

    2015-05-19

    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 The microsurgical anatomy of middle cerebral artery is of particular interest to the cerebrovascular surgeons as it supplies most of the superolateral surface of cerebral hemispheres and is the most commonly involved artery in stroke. The insular segment (M2 segment begins at the limen insulae and runs on the surface of the insula in the sylvian insular cistern with a superoposterior direction. The M2 segment consists of two or three branches that arise from the bifurcation or trifurcation of the M1. After reaching the top of the insula, these branches turn inferolaterally and exit from the sylvian insular cistern forming the M3 segment. OBJECTIVE Certain clinical conditions like aneurysms and glioma of the M2 segment aneurysms demands special attention due to vascular complexity of the insular area and peculiar clinical characteristics. The present study was carried out for a better understanding and to define further the microsurgical anatomy of the insular segment of middle cerebral artery hoping to find immediate application of our findings in the field of microsurgical cerebral revascularisation and better interpretation of radiological angiographic investigations performed in cases of young cerebral haemorrhages. The present study also elaborates the directly observed dissection findings rather than the other studies, which are mostly based on radiological findings. MATERIALS AND METHODS Total 20 Middle Cerebral Arteries (MCA were studied obtained from 10 brains. Meticulous dissection was done and middle cerebral artery and its branches were exposed and cleaned in lateral sulcus on the inferior surface of brain. Digital photographs were taken. The number of samples was based on the availability of cadavers in the mentioned institute during the time of study. RESULT In all 20 MCAs, bifurcation was noted. In 15 out of 20 specimens, more than one major cortical branch was given by M1 segment before its division into secondary trunks at insula

    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.

    Full Text Available Multiple cerebral tuberculomas complicating miliary tuberculosis are a rare occurrence. It is rarer still for multiple cerebral tuberculomas to present without focal neurological deficits. We report the case of a middle-aged Nigerian male with the co-morbidity of miliary tuberculosis and multiple cerebral tuberculomaswho presented without focal neurological deficits buthad complete resolution of symptoms and signs following a 6-month course of antituberculous therapy. This unique case emphasizes the need for a high index of suspicion in the diagnosis of atypical presentations of cerebral tuberculomas while also further illustrating the place of computed tomographic scan of the brain in diagnosis. The case also illustrates the place of therapeutic trial in management.

  8. Neuroprotective effects of female sex steroids in cerebral ischemia

    Full Text Available The central and peripheral nervous system are important targets of sex steroids. Sex steroids affect the brain development and differentiation, and influence neuronal functions. Recent evidence emphasizes a striking sex-linked difference in brain damage after experimental stroke, as well as the efficacy of hormones in treating cerebral stroke injury. Several different models of cerebral ischemia have been utilized for hormone neuroprotection studies, including transient or permanent middle cerebral artery occlusion, transient global ischemia, and transient forebrain ischemia. Extensive experimental studies have shown that female sex steroids such as progesterone and 176-estradiol exert neuroprotective effects in the experimental models of stroke, although deleterious effects have also been reported. Also, a significance of numerous factors, including gender and age of experimental animals, localization of brain lesion, duration of ischemia and precise dose of steroids has been pointed out. There are multiple potential mechanisms that might be invoked to explain the beneficial effects of female sex steroids in brain injury, involving neuroprotection, anti-inflammatory properties, effects on vasculature and altered transcriptional regulation. A several clinical trials on the effects of sex hormones to traumatic brain injury have been performed, suggesting that hormone therapy may represent a new therapeutic tool to combat certain diseases, such as traumatic brain injury. Further basic science studies and randomized clinical trials are necessary to reveal a potential application of these molecules as a new therapeutic strategy.

    C-arm flat detector computed tomography (FDCT) parenchymal blood volume (PBV) measurements allow assessment of cerebral haemodynamics in the neurointerventional suite. This paper explores the feasibility of C-arm computed tomography (CT) PBV imaging and the relationship between the C-arm CT PBV and the MR-PWI-derived cerebral blood volume (CBV) and cerebral blood flow (CBF) parameters in aneurysmal subarachnoid haemorrhage (SAH) patients developing delayed cerebral ischemia (DCI). Twenty-six patients with DCI following aneurysmal SAH underwent a research C-arm CT PBV scan using a biplane angiography system and contemporaneous MR-PWI scan as part of a prospective study. Quantitative whole-brain atlas-based volume-of-interest analysis in conjunction with Pearson correlation and Bland-Altman tests was performed to explore the agreement between C-arm CT PBV and MR-derived CBV and CBF measurements. All patients received medical management, while eight patients (31 %) underwent selective intra-arterial chemical angioplasty. Colour-coded C-arm CT PBV maps were 91 % sensitive and 100 % specific in detecting the perfusion abnormalities. C-arm CT rPBV demonstrated good agreement and strong correlation with both MR-rCBV and MR-rCBF measurements; the agreement and correlation were stronger for MR-rCBF relative to MR-rCBV and improved for C-arm CT PBV versus the geometric mean of MR-rCBV and MR-rCBF. Analysis of weighted means showed that the C-arm CT PBV has a preferential blood flow weighting (∼60 % blood flow and ∼40 % blood volume weighting). C-arm CT PBV imaging is feasible in DCI following aneurysmal SAH. PBV is a composite perfusion parameter incorporating both blood flow and blood volume weightings. That PBV has preferential (∼60 %) blood flow weighting is an important finding, which is of clinical significance when interpreting the C-arm CT PBV maps, particularly in the setting of acute brain ischemia.
