    Rebleeding from subarachnoid haemorrhage (SAH) usually occurs within the first six hours after the initial bleeding. Rebleeding can be prevented effectively with tranexamic acid (TXA). Although a broad consensus has evolved that SAH should be treated as an emergency, it is likely that delays do...

    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.)

  3. Acute Headache at Emergency Department: Reversible Cerebral Vasoconstriction Syndrome Complicated by Subarachnoid Haemorrhage and Cerebral Infarction

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

    Full Text Available 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.

    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.)

    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.

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

    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.

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

    International Nuclear Information System (INIS)

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

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

    Systemic administration of recombinant erythropoietin (EPO) has been demonstrated to mediate neuroprotection. This effect of EPO may in part rely on a beneficial effect on cerebrovascular dysfunction leading to ischaemic neuronal damage. We investigated the in vivo effects of subcutaneously...... administered recombinant EPO on impaired cerebral blood flow (CBF) autoregulation after experimental subarachnoid haemorrhage (SAH).

    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.

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

    2015-03-01

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

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

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

    Subarachnoid haemorrhage (SAH) is characterised by bleeding in the subarachnoid space in the brain. There are various polymorphisms in genes which are associated with this disease. We performed a systematic meta- analysis to investigate the relationship of APOE polymorphism on aSAH. A comprehensive literature search was done in the Pubmed database, Science Direct, Cochrane library and Google Scholar. The OR and 95% CI were evaluated for the gene and aSAH association using fixed and random effect models. Publication bias was assessed using Begg's funnel plot and Egger's regression test. All statistical evaluations were done using the software Review Manager 5.0 and Comprehensive Meta Analysis v2.2.023. A total of 9 studies were assessed on APOE polymorphism (1100 Cases, 2732 Control). Meta analysis results showed significant association in ε2/ ε2 versus ε3/ε3, ε2 versus ε3 genetic models and ε2 allele frequency. In subgroup analysis statistically significant association was observed in Asians in the genetic models ε2/ ε2 versus ε3/ε3, ε2/ε3 versus ε3/ε3, ε2 versus ε3 and also in ε2 allele frequency. However, in Caucasian population only ε2/ε2 versus ε3/ε3 genetic model showed significant association between APOE and risk of aSAH. In this meta-analysis study, the ε2/ε2 genotype is associated with increased risk of aSAH. PMID:27408823

    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.)

The patients were admitted to the Stroke Unit (SU between January 1, 2006, and December 1, 2013. Demographic, clinical, and radiological variables were examined in logistic regression to evaluate independent factors for increasing the risk of death. Results. Patients with systolic blood pressure >160 mmHg (P=0.02, serum glucose >7 mmol/L (P=0.02, aneurysm location in artery communicant anterior (P=0.03, and black/mixed race (P=0.008 were significant related to death in univariate analysis. Risk factors (HTA, smoke, alcohol consumption, and DM, complication, multiplex rebleeding and stage of WFNS, and Fisher’s scale were not related to mortality. Patients with three or more complications had a higher mortality rate (P=0.002. The results of the multivariate logistic regression analysis indicated that race (black/mixed, P=0.00, OR 4.62, and 95% IC 1.40–16.26, systolic blood pressure (>160 mmHg, P=0.05, OR 2.54, and 95% IC 1.01–3.13, and serum glucose (>7.0 mmol/L, P=0.05, OR 1.82, and 95% IC 1.27–2.67 were independent risk factors for death. Conclusions. The black/mixed race, SBP, and serum glucose were independent predictors of mortality. Three or more complications were associated with increasing the probability to death. Further investigation is necessary to validate these findings.

    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.

    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.

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

    Full Text Available Abstract Introduction The prevalence of cardiac arrest among patients with subarachnoid haemorrhage [SAH], and the prevalence of SAH as the cause following out-of-hospital cardiac arrest [OHCA] or in-hospital cardiac arrest [IHCA] is unknown. In addition it is unclear whether cardiopulmonary resuscitation [CPR] and post-resuscitation care management differs, and to what extent this will lead to meaningful survival following cardiac arrest [CA] due to SAH. Aim We reviewed the literature in order to describe; 1.The prevalence and predisposing factors of CA among patients with SAH 2.The prevalence of SAH as the cause of OHCA or IHCA and factors characterising CPR 3.The survival and management of SAH patients with CA. Material and methods The following sources, PubMed, CinAHL and The Cochrane DataBase were searched using the following Medical Subheadings [MeSH]; 1. OHCA, IHCA, heart arrest and 2. subarachnoid haemorrhage. Articles containing relevant data based on the abstract were reviewed in order to find results relevant to the proposed research questions. Manuscripts in other languages than English, animal studies, reviews and case reports were excluded. Results A total of 119 publications were screened for relevance and 13 papers were included. The prevalence of cardiac or respiratory arrest among all patients with SAH is between 3-11%, these patients commonly have a severe SAH with coma, large bleeds and evidence of raised intracerebral pressure on computed tomography scans compared to those who did not experience a CA. The prevalence of patients with SAH as the cause of the arrest among OHCA cases vary between 4 to 8% among those who die before hospital admission, and between 4 to 18% among those who are admitted. The prevalence of SAH as the cause following IHCA is low, around 0.5% according to one recent study. In patients with OHCA survival to hospital discharge is poor with 0 to 2% surviving. The initial rhythm is commonly asystole or

    Context: Poor grade subarachnoid hemorrhage (SAH) is usually associated with unfavorable outcomes and optimal management is deemed complicated. Most centres follow an expectant management strategy or a less aggressive approach till patients improve to good clinical grades. This approach has been associated with higher mortality and morbidity. However, not all patients with poor clinical condition fare badly. Identification and early aggressive management of this select group of patients may lead to favorable outcomes. Settings and Design: Prospective non-randomized study. Materials and Methods: We prospectively analyzed 19 cases presented in WFNS grade 4 and 5 and factors affecting their outcome at a tertiary care centre in south India. This study was aimed at identifying those few poor grade patients who are probable candidates for a good outcome. Statistical Analysis Used: All the variables were analyzed for possible correlations with the SPSS version 13 software. The Chi-square test with a P hydrocephalus underwent extra-ventricular drainage. Statistically significant factors precluding good outcome were the presence of infarcts and thick SAH in the cisterns. Conclusions: Poor grade (WFNS 4 and 5) SAH patients with or without ICH, IVH, if operated within 3 days can give rise to favorable outcome in around 50%. However, presence of patchy infarcts associated with thick subarachnoid blood (Fisher grade 3) precludes long term survival or meaningful recovery. Hence, aggressive management is unlikely to alter the natural history of such patients. PMID:27695539

    International Nuclear Information System (INIS)

    To determine the outcome of treatment of microsurgical clipping in elderly (60 - 70 years) patients with aneurysmal subarachnoid hemorrhage and determine the predictors of poor outcome. Study Design: Longitudinal analytical study. Place and Duration of Study: Nishtar Hospital, Multan, Mayo Hospital, Lahore, Department of Neurosurgery, Lahore General Hospital, Lahore, from January 2000 to January 2010. Methodology: Elderly patients (60 - 70 years) with ruptured cerebral aneurysm were enrolled and graded on the basis of World Federation of Neurosurgeons Scale (WFNS). Aneurysm sac obliteration was done in all the patients with microsurgical clipping. Postoperatively, the patients were assessed upto 3 months for outcome parameters i.e., neurological deterioration (based on WFNS grade and modified Rankin scale as favourable (mRS score 2). The factors associated with unfavourable outcome were also noted which included age > 65 years, poor initial WFNS grade, and the occurrence of ischaemia. Results: The mean age of the 48 patients was 65 + 5.45 years. There were 31 (64.6%) male and 17 (35.4%) female patients. Postprocedural neurological deterioration occurred in 23 patients (47.9%) related to ischaemia in 14 (29.16%), rebleeding in 1 (2%), and hydrocephalus in 8 (16.66%). At 03 months, the outcome was favourable in 25 patients (52.08%) and unfavourable in 23 (47.91%). Conclusion: In old patients, careful pre-operative assessment, interdisciplinary approach and meticulous tissue handling during aneurysm clipping may decrease the unfavourable outcome. (author)

The objective of this study was to assess the prevalence of superficial siderosis after singular, aneurysmal subarachnoid hemorrhage (SAH) in the long term. We retrospectively identified all patients who presented with a singular, acute, aneurysmal SAH at our institution between 2010 and 2013 and in whom a magnetic resonance imaging (MRI) including T2*-weighted imaging was available at least 4 months after the acute bleeding event. MRI scans were judged concerning the presence and distribution of superficial siderosis. Influence of clinical data, Fisher grade, localization, and cause of SAH as well as the impact of neurosurgical interventions on the occurrence of superficial siderosis was tested. Seventy-two patients with a total of 117 MRIs were included. Mean delay between SAH and the last available MRI was 47.4 months (range 4-129). SAH was Fisher grade 1 in 2 cases, 2 in 4 cases, 3 in 10 cases, and 4 in 56 cases. Superficial siderosis was detected in 39 patients (54.2 %). In all patients with more than one MRI scan, localization and distribution of superficial siderosis did not change over time. Older age (p = 0.02) and higher degree of SAH (p = 0.03) were significantly associated with the development of superficial siderosis. Superficial siderosis develops in approximately half of patients after singular, aneurysmal SAH and might be more common in patients with an older age and a greater amount of blood. However, additional factors must play a role in whether a patient is prone to develop superficial siderosis or not. (orig.)

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

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

    Acute adrenal haemorrhage (AAH) is a rare disorder with different aetiologies. Aiming to discuss this condition, this report deals with four different cases that will be analysed and examined below, each one of them confirmed by biopsy or surgery and followed clinically and radiologically. In these cases it was found that the patients suffered from localized abdominal pain (4/4) and fever (2/4); one patient had adrenal insufficiency due to bilateral massive AAH. Therefore we concluded that AAH is an uncommon condition with variable clinical manifestations. PMID:9089038

    Full Text Available Abstract Background Cytokines and cytokine receptor concentrations increase in plasma and cerebrospinal fluid (CSF of patients following subarachnoid haemorrhage (SAH. The relationship between plasma and CSF cytokines, and factors affecting this, are not clear. Methods To help define the relationship, paired plasma and cerebrospinal fluid (CSF samples were collected from patients subject to ventriculostomy. Concentrations of key inflammatory cytokines, interleukin (IL-1ß, IL-1 receptor antagonist (IL-1Ra, IL-1 receptor 2, IL-6, IL-8, IL-10, tumour necrosis factor (TNF-α, and TNF receptors (TNF-R 1 and 2 were determined by immunoassay of CSF and plasma from 21 patients, where samples were available at three or more time points. Results Plasma concentrations of IL-1ß, IL-1Ra, IL-10, TNF-α and TNF-R1 were similar to those in CSF. Plasma TNF-R2 and IL-1R2 concentrations were higher than in CSF. Concentrations of IL-8 and IL-6 in CSF were approximately10 to 1,000-fold higher than in plasma. There was a weak correlation between CSF and plasma IL-8 concentrations (r = 0.26, but no correlation for IL-6. Differences between the central and peripheral pattern of IL-6 were associated with episodes of ventriculostomy-related infection (VRI. A VRI was associated with CSF IL-6 >10,000 pg/mL (P = 0.0002, although peripheral infection was not significantly associated with plasma IL-6. Conclusions These data suggest that plasma cytokine concentrations cannot be used to identify relative changes in the CSF, but that measurement of CSF IL-6 could provide a useful marker of VRI.

    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.

    Early brain injury (EBI) following aneurysmal subarachnoid haemorrhage (SAH) insults contributes to the poor prognosis and high mortality observed in SAH patients. Topiramate (TPM) is a novel, broad-spectrum, antiepileptic drug with a reported protective effect against several brain injuries. The current study aimed to investigate the potential of TPM for neuroprotection against EBI after SAH and the possible dose-dependency of this effect. An endovascular perforation SAH model was established in rats, and TPM was administered by intraperitoneal injection after surgery at three different doses (20mg/kg, 40mg/kg, and 80mg/kg). The animals' neurological scores and brain water content were evaluated, and ELISA, Western blotting and immunostaining assays were conducted to assess the effect of TPM. The results revealed that TPM lowers the elevated levels of myeloperoxidase and proinflammatory mediators observed after SAH in a dose-related fashion, and the nuclear factor-kappa B (NF-κB) signalling pathway is the target of neuroinflammation regulation. In addition, TPM ameliorated SAH-induced cortical neuronal apoptosis by influencing Bax, Bcl-2 and cleaved caspase-3 protein expression, and the effect of TPM was enhanced in a dose-dependent manner. Various dosages of TPM also upregulated the protein expression of the γ-aminobutyric acid (GABA)-ergic signalling molecules, GABAA receptor (GABAAR) α1, GABAAR γ2, and K(+)-Cl(-) co-transporter 2 (KCC2) together and downregulated Na(+)-K(+)-Cl(-) co-transporter 1 (NKCC1) expression. Thus, TPM may be an effective neuroprotectant in EBI after SAH by regulating neuroinflammation and neuronal cell death.

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

    International Nuclear Information System (INIS)

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

    Twenty two patients were entered into a randomised controlled clinical trial comparing the efficacy of somatostatin and vasopressin in controlling acute variceal haemorrhage. Somatostatin was significantly more successful in controlling acute variceal haemorrhage than vasopressin (p = 0.003). Furthermore, no complications were observed during treatment with somatostatin.

    We present a report of a 47-year-old woman with developmental delay who presented with subarachnoid hemorrhage and acute hydrocephalus. She did not have an aneurysm, but there was symmetric calcification and gadolinium-enhancement of the meninges within the Sylvian fissure. Biopsy and genetic testing confirmed transthyretin-type amyloidosis. It is important to consider such rare causes in atypical presentations of non-aneurysmal subarachnoid hemorrhage. PMID:26896372

    Background: Electrocardiogram (ECG) abnormalities following aneurysmal subarachnoid hemorrhage (SAH) have been well documented. Evidence suggests that ECG changes and cardiac dysfunction worsen outcome. Determining which patients are at most risk is unclear but important to ascertain. Methods: We prospectively studied clinical markers, cardiac abnormalities, and clinical outcomes in 20 patients admitted within 48 hours of aneurysmal SAH. All patients had ECGs prior to surgical clipping, during the clipping surgery, and during the postoperative period. Results: The aneurysm was located in the anterior circulation in 17 patients (85%) and in the posterior circulation in 3 patients (15%). Abnormal ECG changes in patients with acute SAH were observed, with a total incidence rate of 65%. The incidence of T wave abnormalities was 53.8% among the patients with ECG changes, 46.2% had ST segment change, and 30.8% had QT interval prolongation. Of the 13 patients with ECG changes, 4 (30.8%) had fluctuating ECG abnormalities (an abnormality that presented and disappeared during the study period or changed in character). All 4 patients with fluctuating ECG changes had a poor outcome (100%) compared to 3 of the 9 patients (33.3%) patients with fixed abnormalities (Paneurysmal SAH. In our group, all the patients who had ECG changes that fluctuated from one abnormal change to another had a poor outcome. The etiology of this finding is not clear but may open the door to further study into the pathogenesis of cardiac changes in aneurysmal SAH. The clinical utility of the variability of ECG abnormalities needs to be validated in a larger cohort of patients with longer follow-up than was possible in this study.

    Full Text Available Background: Bevacizumab is a monoclonal antibody against vascular endothelial growth factor approved by the United States Food and Drug Administration for the treatment of various cancers including refractory high grade glioma. There are case reports of subarachnoid haemorrhage (SAH during bevacizumab treatment though the causative role of the drug in these cases has been obscured by the presence of alternative aetiologies or incomplete investigation. Furthermore, there is no consensus regarding the risk of Central Nervous System (CNS haemorrhage during bevacizumab treatment due to limited available study data. Case Description: A 53 year old female with recurrent gliosarcoma refractory to standard, temozolamide based chemo-radiotherapy presented to our facility in a post-ictal state 16 days after her second dose of intravenous bevacizumab. A Fisher grade III SAH was found on computerised tomography scanning with no causative vascular lesion found on two subsequent digital subtraction angiograms separated by a 10 day period and a Magnetic Resonance Imaging (MRI scan 20 days post-bleed. Given the resolution of symptoms over an uncomplicated 13 day admission, she was discharged home with bevacizumab ceased prior to her scheduled third dose. Conclusion: We discuss here a case of diffuse, non-traumatic SAH during bevacizumab treatment of recurrent gliosarcoma in which alternative aetiologies of haemorrhage were excluded, to our knowledge the first such case in the English language literature. This adverse event is compatible with the known molecular mechanisms of bevacizumab and clinicians should be cognisant of the potential risk of CNS haemorrhage until larger studies are available to quantify this risk.

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

    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

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

    International Nuclear Information System (INIS)

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

    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.)

  19. Hyponatremia in aneurysmal subarachnoid hemorrhage is due to the syndrome of inappropriate antidiuresis and acute glucocorticoid deficiency

    Hyponatraemia is the most common electrolyte abnormality following subarachnoid haemorrhage (SAH) and contributes to increased morbidity and mortality. Retrospective data suggests that the syndrome of inappropriate diuresis (SIAD) is the most common cause of hyponatraemia in SAH, though cerebral salt wasting has been postulated by some workers to be the predominant abnormality. Data which has shown acute glucocorticoid deficiency following SAH has suggested that some cases of euvolaemic hyponatraemia may also be caused by this mechanism.We prospectively studied the hormonal and haemodynamic influences involved in the development of hyponatraemia in 100 patients (61% female, median age 53 (range 16-82)) with non-traumatic aneurysmal SAH. Each patient had plasma sodium (pNa), urea, osmolality, glucose and 0900h cortisol (PC), and urinary sodium and osmolality measured on days 1, 2, 3, 4, 6, 8, 10 and 12 following SAH. Fluid balance and haemodynamic parameters were recorded daily. Results were compared with 15 patients admitted to ITU following vascular surgery. A PC<300nmol\\/L in a patient in ITU was regarded clinically as inappropriately low.49% of patients developed hyponatraemia (pNa<135 mmol\\/L), including 14% who developed clinically significantly hyponatraemia (pNa<130 mmol\\/L). 36\\/49 (73.4%) developed hyponatraemia between days 1 and 3 post SAH. The median duration of hyponatraemia was 3 days (range 1–10 days).In 35\\/49 (71.4%), hyponatraemia was due to SIAD as defined by standard diagnostic criteria. 14% of SAH patients had at least one PC<300nmol\\/L; 5 of these (35.7%) developed hyponatraemia. In 4 patients hyponatraemia was preceded by acute cortisol deficiency and responded to hydrocortisone treatment. In contrast, all controls had PC>500 nmol\\/L on day 1, and >300 nmol on days 3–12. There were no cases of cerebral salt wasting. There was no relationship between the incidence of hyponatraemia and the defined anatomical territory or severity of

    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.)

    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.

    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.

    Abstract Rebleeding of an aneurysm is a major cause of morbidity and mortality after subarachnoid hemorrhage (SAH). Whereas numerous studies have demonstrated predictors of rebleeding and effect of systolic blood pressure variability (SBPV) on stroke, few data on the association between SBPV and rebleeding. Here, we sought to identify the effect of SBPV on rebleeding in acute aneurysmal SAH. Case–control study. From January 2010 to June 2015, 612 patients with aneurysmal SAH were enrolled in our tertiary care medical center. Main outcome measures: Consecutive patients with acute (<3 days from ictus) aneurismal rebleeding or repair or death were retrospectively included. Antihypertensive therapy based on a predefined standardized protocol was prescribed to lower and maintain SBP between 120 and 160 mm Hg. SBP was measured hourly until a censoring event occurred. SBPV was determined as standard deviation (SD) and successive variation (SV). Binary logistic regression was used to assess the association between SBPV and rebleeding. Rebleeding occurred in 61 (10.0%) of the 612 patients. We identified 47 acute rebleeding as cases and 382 early repair or early death as controls. On binary logistic regression analysis, rebleeding was associated with the SD of SBP (odds ratio [OR], 1.254; 95% confidence interval [CI], 1.131–1.391; P < 0.001) and the SV of SBP (OR, 1.131; 95% CI, 1.039–1.231; P = 0.004). No significant difference was seen between rebleeding and mean systolic blood pressure (MSBP). SBPV is associated with increased rates of acute aneurysmal rebleeding. Further prospective research is warranted to confirm that SBP stability prevents acute aneurysm rebleeding. PMID:26986118

    The purpose of this study was to identify common underlying etiologies that may be responsible for isolated acute nontraumatic cortical subarachnoid hemorrhage (cSAH) by analysis of magnetic resonance imaging (MRI) findings of the brain. From August 2005 to February 2014, 15 cSAH patients were admitted to our institution. All patients with cSAH underwent brain MRI and magnetic resonance angiography as a part of their initial evaluation. An analysis of the patients' medical history, clinical presentations, and brain MRI findings was retrospectively performed. Among the combined pathologies that were suspected causes of cSAH, 11 patients showed acute or subacute cerebral infarctions at the ipsilateral hemisphere of cSAH on the diffusion-weighted images. Four of 11 patients had only cerebral infarction, but the other 7 had combined vasculopathy of extra- and intracranial arteries. Four of 15 patients who did not have cerebral infarction, had intracranial artery stenosis, or showed possible cerebral amyloid angiopathy, or no abnormal findings on the brain MRI. Ischemic stroke, such as cerebral infarction or vasculopathy of the extra and intracranial arteries is regarded as a common underlying etiology of the cSAH based on MRI findings.

  6. Management of poor grade subarachnoid hemorrhage. Unsolved problems in the ultra-acute phase

    International Nuclear Information System (INIS)

    We evaluated the management of patients with subarachnoid hemorrhage (SAH) after arrival for surgical intervention in the ultra-acute stage. Immediately after brief neurological and systemic examination, patients were deeply sedated to prevent aneurysmal rerupture. Principally they were intubated with intensive control of systolic blood pressure below 120 mmHg by radial arterial monitoring. Buprenorphine, midazolam, and vecuronium were routinely intravenously administered; and propofol, barbiturate, nicardipine, or prostaglandin was added to lower blood pressure if necessary. A total of 163 consecutive patients with SAH (59 men and 104 women, mean age of 61.1 years) arrived between 2003 and 2005 were enrolled. The majority of patients were in poor grade: 26 with Grade IV, 54 with Grade V by grading scale of the World Federation of Neurological Society, and 32 with cardiopulmonary arrest. Eighty-seven patients (53%) arrived within 1 hour after onset of SAH and 127 patients (78%) arrived within 3 hours. Most of the poor-grade patients were intubated before initial brain CT scan. Mean systolic blood pressure was around 170 mmHg at the time of arrival, which was controlled around 120 mmHg or less during resuscitation and angiography. A total of 117 patients had DSA, 111 of them (68%) within 3 hours, and 111 patients underwent surgery, 81 of them (85%) within 6 hours. Despite intensive resuscitation, 36 episodes of rebleeding were detected in 32 patients, 24 before and 12 after arrival. Extravasation of contrast media was seen in 6 patients during cerebral angiography. Favorable outcome (good recovery and moderate disability) was obtained in 69% of Grade IV and 24% of the Grade V patients. The risk of ultra-early rebleeding is highest for patients with poor grades. Deep sedation and strict blood pressure control followed by urgent obliteration of the ruptured aneurysm have a strong rationale to prevent rerupture and to achieve better overall outcome. (author)

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

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

    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.

    To assess the feasibility of dual energy computed tomography (DE-CT) in intra-arterially treated acute ischaemic stroke patients to discriminate between contrast extravasation and intracerebral haemorrhage. Thirty consecutive acute ischaemic stroke patients following intra-arterial treatment were examined with DE-CT. Simultaneous imaging at 80 kV and 140 kV was employed with calculation of mixed images. Virtual unenhanced non-contrast (VNC) images and iodine overlay maps (IOM) were calculated using a dedicated brain haemorrhage algorithm. Mixed images alone, as ''conventional CT'', and DE-CT interpretations were evaluated and compared with follow-up CT. Eight patients were excluded owing to a lack of follow-up or loss of data. Mixed images showed intracerebral hyperdense areas in 19/22 patients. Both haemorrhage and residual contrast material were present in 1/22. IOM suggested contrast extravasation in 18/22 patients; in 16/18 patients this was confirmed at follow-up. The positive predictive value (PPV) of mixed imaging alone was 25 %, with a negative predictive value (NPV) of 91 % and accuracy of 63 %. The PPV for detection of haemorrhage with DE-CT was 100 %, with an NPV of 89 % and accuracy improved to 89 %. Dual energy computed tomography improves accuracy and diagnostic confidence in early differentiation between intracranial haemorrhage and contrast medium extravasation in acute stroke patients following intra-arterial revascularisation.

    To investigate the clinical implications of microvascular obstruction (MVO) and intramyocardial haemorrhage (IMH) in acute myocardial infarction (AMI). Ninety patients with a first AMI undergoing primary percutaneous coronary intervention (PCI) were studied. T2-weighted, cine and late gadolinium-enhanced cardiovascular magnetic resonance imaging was performed at 5 {+-} 2 and 103 {+-} 11 days. Patients were categorised into three groups based on the presence or absence of MVO and IMH. MVO was observed in 54% and IMH in 43% of patients, and correlated significantly (r = 0.8, p < 0.001). Pre-PCI thrombolysis in myocardial infarction 3 flow was only observed in MVO(-)/IMH(-) patients. Infarct size and impairment of systolic function were largest in MVO(+)/IMH(+) patients (n = 39, 23 {+-} 9% and 47 {+-} 7%), smallest in MVO(-)/IMH(-) patients (n = 41, 8 {+-} 8% and 55 {+-} 8%) and intermediate in MVO(+)/IMH(-) patients (n = 10, 16 {+-} 7% and 51 {+-} 6%, p < 0.001). LVEF increased in all three subgroups at follow-up, but remained intermediate in MVO(+)/IMH(-) and was lowest in MVO(+)/IMH(+) patients. Using random intercept model analysis, only infarct size was an independent predictor for adverse LV remodelling. Intramyocardial haemorrhage and microvascular obstruction are strongly related. Pre-PCI TIMI 3 flow is less frequently observed in patients with MVO and IMH. Only infarct size was an independent predictor of LV remodelling. (orig.)

    To evaluate the clinical role of CT angiography (CTA) in patients with acute subarachnoid hemorrhage (SAH) for treatment decision-making. Consecutive patients with acute SAH had CTA using a 64-slice scanner for initial clinical decision-making. Image processing included multiplanar volume reformatted (MPVR) maximum intensity projections (MIP) and 3D volume-rendered reconstructions. CTAs were used for (1) evaluating the cause of SAH, and (2) triaging aneurysm-bearing patients to the more appropriate management, either surgical clipping or endovascular coiling. CTA findings were confirmed by neurosurgical exploration or catheter angiography (digital subtraction angiography, DSA). Successful coiling provided evidence that triaging to endovascular treatment was correct. Included in the study were 73 patients. CTA findings were confirmed by DSA or neurosurgical operation in 65 patients, and of these 65, 47 had aneurysmal SAH, 3 had vasculitis, 1 had arterial dissection and 14 had no underlying arterial abnormality. The cause of SAH was detected with CTA in 62 out of the 65 patients (95.4%, sensitivity 94%, specificity 100%). CTA revealed the aneurysm in 46 of 47 patients (98%, sensitivity 98%, specificity 100%, positive predictive value 100%, negative predictive value 82.3%), 1 of 3 vasculitides and 1 of 1 dissection. Of the 46 patients with aneurysm, 44 (95.7%) were referred for treatment based on CTA. In 2 patients (2 of 46, 4.4%) CTA was not informative enough to choose treatment requiring DSA. Of the 44 patients, 27 (61.4%) were referred to endovascular treatment and successful coiling was achieved in 25 (25 of 27, 92.6%). CTA using a 64-slice scanner is an accurate tool for detecting and characterizing aneurysms in acute SAH. CTA is useful in the decision process whether to coil or clip an aneurysm. (orig.)

    Full Text Available Hydrogen can relieve tissue-damaging oxidative stress, inflammation and apoptosis. Injection of hydrogen-rich saline is an effective method for transporting molecular hydrogen. We hypothesized that hydrogen-rich saline would promote the repair of spinal cord injury induced by Allen′s method in rats. At 0.5, 1, 2, 4, 8, 12 and 24 hours after injury, then once daily for 2 weeks, 0.25 mL/kg hydrogen-rich saline was infused into the subarachnoid space through a catheter. Results at 24 hours, 48 hours, 1 week and 2 weeks after injury showed that hydrogen-rich saline markedly reduced cell death, inflammatory cell infiltration, serum malondialdehyde content, and caspase-3 immunoreactivity, elevated serum superoxide dismutase activity and calcitonin gene-related peptide immunoreactivity, and improved motor function in the hindlimb. The present study confirms that hydrogen-rich saline injected within 2 weeks of injury effectively contributes to the repair of spinal cord injury in the acute stage.

  17. Urea for treatment of acute SIADH in patients with subarachnoid hemorrhage: a single-center experience

    Science.gov (United States)

    2012-01-01

    Background Hyponatremia occurring as a result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) or cerebral salt wasting syndrome is a common complication in patients with subarachnoid hemorrhage (SAH). The efficacy and safety of urea as treatment for SIADH-induced hyponatremia has not been reported in this population. Methods This is a retrospective analysis of all patients admitted to our department for nontraumatic SAH between January 2003 and December 2008 (n = 368). All patients with SIADH-induced hyponatremia (plasma sodium  20 mEq/L, and osmolality > 200 mOsm/kg; absence of overt dehydration or hypovolemia; no peripheral edema or renal failure; no history of adrenal or thyroid disease) routinely received urea per os when hyponatremia was associated with clinical deterioration or remained less than 130 mEq/L despite saline solution administration. Results Forty-two patients developed SIADH and were treated with urea. Urea was started after a median of 7 (IQR, 5–10) days and given orally at doses of 15–30 g tid or qid for a median of 5 (IQR, 3–7) days. The median plasma sodium increase over the first day of treatment was 3 (IQR, 1–6) mEq/L. Hyponatremia was corrected in all patients, with median times to Na+ >130 and >135 mEq/L of 1 (IQR, 1–2) and 3 (IQR, 2–4) days, respectively. Urea was well tolerated, and no adverse effects were reported. Conclusions Oral urea is an effective and well-tolerated treatment for SIADH-induced hyponatremia in SAH patients. PMID:22647340

    Digital subtraction angiography (DSA) has been used as the standard method for detecting cerebral vasospasm after subarachnoid hemorrhage (SAH). Multislice computed tomographic angiography (CTA) is a relatively recent method used for evaluating the vasculature of the intracranial arteries. The purpose of this study was to compare multislice CTA and DSA for the detection and quantification of cerebral vasospasm after SAH, and to analyze the usefulness of multislice CTA. Eight patients with SAH underwent initial CTA with DSA within 72 hours after the onset of symptoms and follow-up multislice CTA and DSA 8 to 48 days after SAH. Five arterial locations were established in the A1 and A2 segments of the anterior cerebral artery, the M1 and M2 segments of the middle cerebral artery and the posterior cerebral artery (PCA) on both multislice CTA and DSA images. Vasospasm was classified as none, mild (up to 30% reduction in luminal diameter), moderate (31-60% reduction), and marked (at least 60% reduction) using the scale of Schneck and Kricheff. The multislice CT system used the following parameters: 1.25 mm collimation and 3.75 pitch with a 4-channel system. The degree of vasospasm revealed by the multislice CTA was significantly correlated with the degree of vasospasm revealed by DSA. In general, most discrepancies between CTA and DSA were in the detection of mild and moderate vasospasm. We found that the consistency between multislice CTA and DSA was greater for mild (100%, n=3) or moderate (100%, n=3) vasospasm than none (n=1) or marked vasospasm (n=1). However, it was unclear whether multislice CTA was more specific for a proximal location (A1, M1, PCA) or distal location (A2, M2) for evaluation of cerebral arteries. Multislice CTA can detect angiographic vasospasm after SAH with an accuracy similar to that of DSA. Multislice CTA is highly sensitive, specific and accurate in detecting mild and moderate cerebral vasospasm. It is less accurate for detecting no vasospasm

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

    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.

    For patients presenting with acute brain injury (such as traumatic brain injury, subarachnoid haemorrhage and stroke), the diagnosis and identification of intracerebral lesions and evaluation of the severity, prognosis and treatment efficacy can be challenging. The complexity and heterogeneity of lesions after brain injury are most probably responsible for this difficulty. Patients with apparently comparable brain lesions on imaging may have different neurological outcomes or responses to therapy. In recent years, plasmatic and cerebrospinal fluid biomarkers have emerged as possible tools to distinguish between the different pathophysiological processes. This review aims to summarise the plasmatic and cerebrospinal fluid biomarkers evaluated in subarachnoid haemorrhage, traumatic brain injury and stroke, and to clarify their related interests and limits for diagnosis and prognosis. For subarachnoid haemorrhage, particular interest has been focused on the biomarkers used to predict vasospasm and cerebral ischaemia. The efficacy of biomarkers in predicting the severity and outcome of traumatic brain injury has been stressed. The very early diagnostic performance of biomarkers and their ability to discriminate ischaemic from haemorrhagic stroke were studied.

    In this retrospective study, we examined the usefulness of computed tomographic angiography (CTA) for the detection and assessment of circle of Willis aneurysms in patients with acute nontraumatic subarachnoid hemorrhage (SAH), using selective digital substraction angiography (DSA) as the gold standard. Thirty-five patients who presented with acute, nontraumatic SAH, diagnosed on the basis of unenhanced computed tomography or lumbar puncture findings or both, underwent both CTA and DSA. The CTA images were interpreted for the presence, location, size, and shape of the aneurysm, presence of a neck, and relationship of the aneurysm to adjacent arterial branches. The CTA and DSA images were then compared, with the latter images serving as the gold standard. DSA revealed 37 aneurysms in 32 patients and ruled out intracranial aneurysms in the remaining three. The sensitivity and specificity of CTA for aneurysm detection were 97% and 100%, respectively. The size of the smallest aneurysm shown was 4 mm, and the largest aneurysm was 21 mm. The size and lobularity of the aneurysms estimated from CTA images corresponded well with those estimated from DSA images. In addition, CTA provided a three-dimensional representation of the aneurysmal lesion, which was considered useful for surgical planning. Our results confirm the accuracy of CTA in comparison with DSA. Because of its reliability, minimal invasiveness, and rapidity, CTA may become the technique of choice for neuroradiologic work-up of SAH patients. DSA then would be used to diagnose intracranial aneurysms only in selected, questionable cases. PMID:10575836

    Toll-like receptor 4 (TLR4) has been proven to play a critical role in neuroinflammation and to represent an important therapeutic target following subarachnoid hemorrhage (SAH). Resveratrol (RSV), a natural occurring polyphenolic compound, has a powerful anti-inflammatory property. However, the underlying molecular mechanisms of RSV in protecting against early brain injury (EBI) after SAH remain obscure. The purpose of this study was to investigate the effects of RSV on the TLR4-related inflammatory signaling pathway and EBI in rats after SAH. A prechiasmatic cistern SAH model was used in our experiment. The expressions of TLR4, high-mobility group box 1 (HMGB1), myeloid differentiation factor 88 (MyD88), and nuclear factor-κB (NF-κB) were evaluated by Western blot and immunohistochemistry. The expressions of Iba-1 and pro-inflammatory cytokines in brain cortex were determined by Western blot, immunofluorescence staining, or enzyme-linked immunosorbent assay. Neural apoptosis, brain edema, and neurological function were further evaluated to investigate the development of EBI. We found that post-SAH treatment with RSV could markedly inhibit the expressions of TLR4, HMGB1, MyD88, and NF-κB. Meanwhile, RSV significantly reduced microglia activation, as well as inflammatory cytokines leading to the amelioration of neural apoptosis, brain edema, and neurological behavior impairment at 24 h after SAH. However, RSV treatment failed to alleviate brain edema and neurological deficits at 72 h after SAH. These results indicated that RSV treatment could alleviate EBI after SAH, at least in part, via inhibition of TLR4-mediated inflammatory signaling pathway. PMID:27529233

    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.

    Dengue is an acute febrile disease caused by the mosquito-borne dengue virus (DENV) that according to clinical manifestations can be classified as asymptomatic, mild or severe dengue. Severe dengue cases have been associated with an unbalanced immune response characterised by an over secretion of inflammatory cytokines. In the present study we measured type I interferon (IFN-I) transcript and circulating levels in primary and secondary DENV infected patients. We observed that dengue fever (DF) and dengue haemorrhagic fever (DHF) patients express IFN-I differently. While DF and DHF patients express interferon-α similarly (52,71 ± 7,40 and 49,05 ± 7,70, respectively), IFN- β were associated with primary DHF patients. On the other hand, secondary DHF patients were not able to secrete large amounts of IFN- β which in turn may have influenced the high-level of viraemia. Our results suggest that, in patients from our cohort, infection by DENV serotype 3 elicits an innate response characterised by higher levels of IFN- β in the DHF patients with primary infection, which could contribute to control infection evidenced by the low-level of viraemia in these patients. The present findings may contribute to shed light in the role of innate immune response in dengue pathogenesis. PMID:27223651

    Intramyocardial haemorrhage (IMH) and microvascular obstruction (MVO) represent reperfusion injury after reperfused ST-elevation myocardial infarction (STEMI) with prognostic impact and ''hypointense core'' (HIC) appearance in T{sub 2}-weighted images. We aimed to distinguish between IMH and MVO by using T{sub 2}{sup *}-weighted cardiovascular magnetic resonance imaging (CMR) and analysed influencing factors for IMH development. A total of 151 patients with acute STEMI underwent CMR after primary angioplasty. T{sub 2}-STIR sequences were used to identify HIC, late gadolinium enhancement to visualise MVO and T{sub 2}{sup *}-weighted sequences to detect IMH. IMH{sup +}/IMH{sup -} patients were compared considering infarct size, myocardial salvage, thrombolysis in myocardial infarction (TIMI) flow, reperfusion time, ventricular volumes, function and pre-interventional medication. Seventy-six patients (50 %) were IMH{sup +}, 82 (54 %) demonstrated HIC and 100 (66 %) MVO. IMH was detectable without HIC in 16 %, without MVO in 5 % and HIC without MVO in 6 %. Multivariable analyses revealed that IMH was associated with significant lower left ventricular ejection fraction and myocardial salvage index, larger left ventricular volume and infarct size. Patients with TIMI flow grade ≤1 before angioplasty demonstrated IMH significantly more often. IMH is associated with impaired left ventricular function and higher infarct size. T{sub 2} and HIC imaging showed moderate agreement for IMH detection. T{sub 2}{sup *} imaging might be the preferred CMR imaging method for comprehensive IMH assessment. (orig.)

    2016-09-01

    Subarachnoid hemorrhage (SAH) is a debilitating, although uncommon, type of stroke with high morbidity, mortality, and economic impact. Modern 30-day mortality is as high as 40%, and about 50% of survivors have permanent disability. Care at high-volume centers with dedicated neurointensive care units is recommended. Euvolemia, not hypervolemia, should be targeted, and the aneurysm should be secured early. Neither statin therapy nor magnesium infusions should be initiated for delayed cerebral ischemia. Cerebral vasospasm is just one component of delayed cerebral edema. Hyponatremia is common in subarachnoid hemorrhage and is associated with longer length of stay, but not increased mortality.

    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.

    A subarachnoid haemorrhage (SAH) occurred 67 days after cardiac transplantation in 10-year-old girl with consecutive immunocompromising therapy. Neither digital subtraction angiography (DSA) nor computed tomographic angiography showed signs of intracranial vascular malformations. One month before the lethal SAH occurred, she had developed arterial hypertension and attacks of severe headache with cerebrospinal fluid (CSF) pleocytosis while CT scans showed an infarct of the left thalamus. Pathologic findings established the rare diagnosis of SAH due to aspergillosis-related mycotic arteritis. Imaging characteristics are presented. (orig.)

    The rupture and bleeding of intracranial aneurysms is the most common cause of a spontaneous, non-traumatic subarachnoid hemorrhage (SAH). In up to 20% of these patients, no aneurysm is found, but the prognosis of these patients is known to be better than in those with aneurysms. The retrospective evaluation of the initial CT- and angiographic findings of 773 patients with spontaneous SAH, who underwent (up to three) 4-vessel DSA, brought a percentage of 12.4% with negative angiography. We found the favourable prognosis of these patients with negative angiography not only to be dependent from the distribution of the hemorrhage, with preference to perimesencephalic pattern, but the initial clinical state. 85% of our patients, who presented with perimesencephalic blood pattern and even 80% of those patients with additional intraventricular hemorrhage but the good clinical condition of Hunt-Hess I/II were discharged without neurological deficits. We recommend the obligatory 4-vessel catheter-angiography (DSA) in all patients with spontaneous SAH, independent of the blood pattern on initial CT, and one control in the presence of other than perimesencephalic subarachnoid hemorrhage, CTA might be reserved for additional controls.

    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 Maternal death in an unmarried woman poses a medico-legal challenge. A 24-year-old unmarried schoolteacher, residing at a boarding place, had been admitted to hospital in a state of cardiac arrest. At the autopsy, mild to moderate congestion of subarachnoid vessels and oedema of the brain was noted. An un-interfered foetus of 15 weeks with an intact sac and placental tissues were seen. Genital tract injuries were not present. Histopathological examination showed diffuse perivascular cuffing by mononuclear cells suggestive of viral encephalitis, considering the circumstances of death and the social stigma of pregnancy in this unmarried teacher, the possibility of attempted suicide by ingestion of a poison was considered. Abrus precatorius (olinda seeds commonly found in the area is known to produce acute encephalitis as well as haemorrhagic gastroenteritis and pulmonary congestion was also considered as a possible cause for this unusual presentation

    Full Text Available Subarachnoid hemorrhage (SAH is one of the major cause of mortality for stroke. The leading cause is the rupture of an intracrnial aneurym. Acute aneurysmal subarachnoid hemorrhage (SAH is a complex multifaceted disorder that plays out over days to weeks. The development of aneurysms is mainly due to a hemodynamic stress. Considerableadvances have been made in endovascular techniques, diagnostic methods, and surgical and perioperative management guidelines. Rebleeding remains the most imminent danger until the aneurysm is excluded from cerebral circulation. The only effective prevention of rebleeding is repair the aneurysm; choosing the right way with surgical or an endovascular approach. Outcome for patients with SAH remains poor, with population-based mortality rates as high as 45% and significant morbidity among survivors. In this work we analyzed the diagnostic-therapeutic course of patients presenting SAH. We analyzed the types and the occurrence of complications. We present two cases report to better demonstrate that treatments for specific patients need to be individualized.

    2012-01-01

    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.

    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.

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

    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.

    2015-01-01

    Troponin (tr) elevation in aneurysmal subarachnoid hemorrhage (SAH) patients is often difficult to be appropriately assessed by clinicians, causing even disagreements regarding its management between neurosurgeons and cardiologists. The purpose of this article was to review the literature regarding the clinical interpretation of tr elevation in SAH. We searched for articles in PubMed using the key words:“troponin elevation”and“subarachnoid hemorrhage”. All of them, as well as relative neurosurgical books, were used for this review. Some type of cardiovascular abnormality develops in most SAH patients. Neurogenic stunned myocardium is a frequent SAH complication, due to catecholamine surge which induces cardiac injury, as evidenced by increased serum tr levels, electrocardiographic (ECG) changes and cardiac wall motion abnormalities. Tr elevation, usually modest, is an early and specific marker for cardiac involvement after SAH and its levels peak about two days after SAH. Cardiac tr elevation predictors include poor clinical grade, intraventricular hemorrhage, loss of consciousness at ictus, global cerebral edema, female sex, large body surface area, lower systolic blood pressure, higher heart rate and prolonged Q-Tc interval. Elevated tr levels are associated with disability and death (especially tr>1μg/L), worse neurological grade, systolic and diastolic cardiac dysfunction, pulmonary congestion, longer intensive care unit stay and incidence of vasospasm. Tr elevation is a common finding in SAH patients and constitutes a rightful cause of worry about the patients’ cardiac function and prognosis. It should be therefore early detected, carefully monitored and appropriately managed by clinicians.

    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.

  4. Patch: platelet transfusion in cerebral haemorrhage: study protocol for a multicentre, randomised, controlled trial

    2010-03-01

    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.

  5. Subarachnoid cyst in a cat

    International Nuclear Information System (INIS)

    A five-year-old domestic longhair was presented with hind-limb ataxia and some degree of incontinence of two weeks' duration. An enlarged spinal canal from the twelfth thoracic (T-12) vertebra to the third lumbar (L(3)) vertebra was identified on survey radiographs. An intradural-extramedullary cavity at the twelfth (T-12) and thirteenth (T-13) thoracic vertebrae, filled with contrast material, was demonstrated on myelography. A left-sided hemilaminectomy was performed over this region, and a subarachnoid cavitation or cyst was found to be the cause of the severe spinal-cord compression. The cyst was drained. The cat showed improvement in the neurological signs during the first three weeks postoperatively. Six months later no neurological deficits were identified on follow-up examination

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

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

  12. Prolonged Paroxysmal Sympathetic Storming Associated with Spontaneous Subarachnoid Hemorrhage

    Full Text Available Paroxysmal sympathetic storming (PSS is a rare disorder characterized by acute onset of nonstimulated tachycardia, hypertension, tachypnea, hyperthermia, external posturing, and diaphoresis. It is most frequently associated with severe traumatic brain injuries and has been reported in intracranial tumors, hydrocephalous, severe hypoxic brain injury, and intracerebral hemorrhage. Although excessive release of catecholamine and therefore increased sympathetic activities have been reported in subarachnoid hemorrhage (SAH, there is no descriptive report of PSS primarily caused by spontaneous SAH up to date. Here, we report a case of prolonged PSS in a patient with spontaneous subarachnoid hemorrhage and consequent vasospasm. The sympathetic storming started shortly after patient was rewarmed from hypothermia protocol and symptoms responded to Labetalol, but intermittent recurrence did not resolve until 3 weeks later with treatment involving Midazolam, Fentanyl, Dexmedetomidine, Propofol, Bromocriptine, and minimizing frequency of neurological and vital checks. In conclusion, prolonged sympathetic storming can also be caused by spontaneous SAH. In this case, vasospasm might be a precipitating factor. Paralytics and hypothermia could mask the manifestations of PSS. The treatment of the refractory case will need both timely adjustment of medications and minimization of exogenous stressors or stimuli.

    Nearly all men with spinal cord injury suffer from neurogenic sexual dysfunction which is often treated with phosphodiesterase-5 (PDE5) inhibitors. We describe a case of subarachnoid hemorrhage due to autonomic dysreflexia (AD) caused by sexual stimulation. Nitrates are frequently used for acute treatment of AD; however, the use of these drugs in combination with PDE5 inhibitors is contraindicated. Therefore, meticulous information from patients and relatives on the risk of AD and possible drug interactions is of vital importance. PMID:23784679

    The understanding of the anatomy of the subarachnoid cisterns and trabecular membranes is of paramount importance in the surgical treatment of pathology of the posterior fossa. Aneurysms, arteriovenous malformations, and some tumors should be approached through the subarachnoid space. The subarachnoid cisterns provide natural pathways to approach neurovascular and cranial nerve structures. The microsurgical anatomy of the infratentorial subarachnoid cisterns was studied in twenty adult brains, using the 'immersion technique'. Air was injected into the subarachnoid cisterns and brains were dissected under the operative microscope. Six main compartmental trabecular membranes were identified in the infratentorial level. They divide the subarachnoid space into six cisterns. Cisternal divisions and the disposition of the trabecular membranes were closely related to the vascular divisional patterns of the principal arteries. Thorough knowledge of the microsurgical anatomy of the subarachnoid space will aid neurosurgeons during the surgical approach of many vascular and tumoral lesions located in the posterior fossa.

    The objective of the study is to investigate the anti-snake venom activities of a local plant, Hibiscus aethiopicus L. The H. aethiopicus was dried and extracted with ethanol. Different assays were performed according to standard techniques, to evaluate the plant's acute toxicity and its antivenom activities. The results of evaluating the systemic acute toxicity of the H. aethiopicus extract using "oral and intra-peritoneal" route were normal even at the highest dose (24 g/kg) tested. All guinea pigs (n = 3) when treated with venoms E. c. sochureki (75 μg) alone induced acute skin haemorrhage. In contrast, all guinea pigs (n = 18) treated with both venom and the plant extract at a concentration between 500 and 1000 mg/kg showed no signs of haemorrhage. Moreover, all guinea pigs (n = 18) treated with venom and the plant extract below 400 mg/kg showed acute skin haemorrhage. All guinea pigs treated with venom E. c. sochureki (75 μg) alone induced acute skin haemorrhage after both 24 and 32 hours. In contrast, all guinea pigs treated with both venom and the plant extract (administered independently) at concentrations between 500 and 1000 mg/kg showed no signs of haemorrhage after 32 hours. However, after 24 hours all tested guinea pigs showed less inhibition (aethiopicus plant may contain an endogenous inhibitor of venom induced local haemorrhage. PMID:22666294

    Burr-hole drainage of chronic subdural hematomas are routine operative procedures done by neurosurgical residents. Common postoperative complications include acute epidural and/or subdural bleeding, tension pneumocephalus, intracranial hematomas and ischemic cerebral infarction. We report an interesting post-operative complication of a 'subarachnoid cyst' after burr-hole evacuation of a chronic subdural hematoma. The authors hypothesize that the 'cyst' is likely secondary to the splitting of the adjacent neomembrane within its arachnoid-brain interface by iatrogenic irrigation of the subdural space. Over time, this 'cyst' develops into an area of gliosis which eventually causes long-term scar epilepsy in the patient. As far as we are aware, this is the first complication of such a 'subarachnoid cyst' post burr-hole drainage reported in the literature. PMID:27366276

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

    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.

    It is still unclear how often subarachnoid hemorrhage (SAH) leads to chronic hemosiderin depositions. In this study, we aimed to determine the frequency of chronic hemosiderin depositions after aneurysmal SAH in patients who did not undergo surgery. Furthermore, we analyzed typical MRI patterns of chronic SAH and sought to obtain information on the temporal course of MRI signal changes. We retrospectively analyzed 90 patients who had undergone endovascular treatment for acute aneurysmal SAH. In all patients, initial CT studies and at least one T2*-weighted MRI obtained 6 months or later after SAH were analyzed for the presence and anatomical distribution of SAH or chronic hemosiderin depositions. In total, 185 T2*-weighted MRI studies obtained between 2 days and 148 months after SAH were evaluated (mean follow-up 30.2 months). On MRI studies obtained later than 6 months after SAH, subpial hemosiderin depositions were found in 50 patients (55.5 %). Most frequent localizations were the parenchyma adjacent to the frontal and parietal sulci and the insular cisterns. While the appearance of hemosiderin depositions was dynamic within the first 3 months, no changes were found during subsequent follow-up. MR signal changes were not only conclusive with subarachnoid hemosiderin depositions but in many cases also resembled those that have been associated with cortical hemosiderosis. T2*-weighted MRI is an effective means of diagnosing prior SAH. Our study suggests that chronic hemosiderin depositions can be found in a considerable number of patients after a single event of subarachnoid hemorrhage. (orig.)

    Objectives: Aim of this study was to compare the utility of susceptibility weighted imaging (SWI) with the established diagnostic techniques CT and fluid attenuated inversion recovery (FLAIR) in their detecting capacity of subarachnoid hemorrhage (SAH), and further to compare the combined SWI/FLAIR MRI data with CT to evaluate whether MRI is more accurate than CT. Methods: Twenty-five patients with acute SAH underwent CT and MRI within 6 days after symptom onset. Underlying pathology for SAH was head trauma (n = 9), ruptured aneurysm (n = 6), ruptured arteriovenous malformation (n = 2), and spontaneous bleeding (n = 8). SWI, FLAIR, and CT data were analyzed. The anatomical distribution of SAH was subdivided into 8 subarachnoid regions with three peripheral cisterns (frontal-parietal, temporal-occipital, sylvian), two central cisterns and spaces (interhemispheric, intraventricular), and the perimesencephalic, posterior fossa, superior cerebellar cisterns. Results: SAH was detected in a total of 146 subarachnoid regions. CT identified 110 (75.3%), FLAIR 127 (87%), and SWI 129 (88.4%) involved regions. Combined FLAIR and SWI identified all 146 detectable regions (100%). FLAIR was sensitive for frontal-parietal, temporal-occipital and Sylvian cistern SAH, while SWI was particularly sensitive for interhemispheric and intraventricular hemorrhage. Conclusions: By combining SWI and FLAIR, MRI yields a distinctly higher detection rate for SAH than CT alone, particularly due to their complementary detection characteristics in different anatomical regions. Detection strength of SWI is high in central areas, whereas FLAIR shows a better detection rate in peripheral areas.

    anticoagulant, together with other drugs, among which were non steroid anti-inflammatory drugs and a domestic organic solvent. The individual died in the Intensive Care Unit, with acute respiratory insufficiency, followed by hepatic and renal failure. At autopsy round haemorrhagic lesions were seen, which affected several tissues, among which were mesenteric fat, the epicardium, and the peri-renal fat. Microscopic study revealed the existence of a typical acute haemorrhagic lesion, located around the epicardial vegetative nerves and those found in the splanchnic beds. The reason why the peripheral vegetative nerves constitute the target of the toxic effects is attributed to the combined action of the solvents together with the superwarfarin drug, on the Peripheral Nervous System. It is known that organic solvents produce an acute neuronal lesion, consisting in tumefaction of the axon and the neuronal soma, which leads to the alteration of the system of transport (neurotubules along the axon. We believe that - from a physiological point of view - the reactive vascular congestion of the vasa-nervorum, produced as a consequence of the acute neuronal lesion induced by the solvents, together with the state of hipocoagulability of the blood - due to the ingestion of the superwarfarin (Brodifacoum and potentiated by the the anticoagulant action of the non steroid anti-inflammatory drugs - make up the intimate mechanisms which could explain this characteristic Acute Toxic Haemorrhagic Neuropathy of the peripheral nerves of the Neurovegetative Nervous System. We do not know if the mixed peripheral nerves were affected by this lesion, due to absence of samples for a more definitive study.

    Abstract Rabbit haemorrhagic disease virus (RHDV) is a calicivirus of the genus Lagovirus that causes rabbit haemorrhagic disease (RHD) in adult European rabbits (Oryctolagus cuniculus). First described in China in 1984, the virus rapidly spread worldwide and is nowadays considered as endemic in several countries. In Australia and New Zealand where rabbits are pests, RHDV was purposely introduced for rabbit biocontrol. Factors that may have precipitated RHD emergence remain unclear, but non-p...

    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.

    Intrathecal spinal catheters (lumbar drains) are indicated for several medical and surgical conditions. In neurosurgical procedures, they are used to reduce intracranial and intrathecal pressures by diverting CSF. They have also been placed for therapeutic access to administer drugs, and more recently, vascular surgeons have used them to improve spinal cord perfusion during the treatment of thoracic aortic aneurysms. Insertion of these lumbar drains is not without attendant complications. One complication is the shearing of the distal end of the catheter with a resultant retained fragment. The authors report the case of a 65-year-old man who presented with a subarachnoid hemorrhage due to the migration of a retained lumbar drain that sheared off during its removal. To the best of the authors' knowledge, this is the first case of rostral migration of a retained intrathecal catheter causing subarachnoid hemorrhage. The authors review the literature on retained intrathecal spinal catheters, and their findings support either early removal of easily accessible catheters or close monitoring with serial imaging.

    Full Text Available CONTEXT: Computed tomographic angiography (CTA is widely applied in the evaluation of cerebral vessels. Contrast enhancement in cerebral CTA without care or test bolus is not always sufficient for high-quality images. AIMS: Evaluation of the possibilities of calculation of scan delay for cerebral CTA in case of subarachnoid hemorrhage (SAH, based on clinical data of a patient and to find out prognostic error of the model. SETTINGS AND DESIGN: Prospective study in Neurosurgery and Radiology departments. MATERIALS AND METHODS: Scan delay in 53 patients suffering an acute SAH was measured employing test bolus technique. Cerebral CTA was performed afterwards. STATISTICAL ANALYSIS USED: SPSS for Windows v.10.1 software package was applied for dispersion analysis, including one-sample Kolmogorov-Smirnov′s test and Levene′s Test of Equality of Error Variances. RESULTS: A statistical model for the prediction of scan delay in SAH was developed. Cerebral CTA scan delay was dependent upon age, neurological status and impact of the latter factors together (P<0.05. The determined mean square error of prognosis of scan delay of the developed model equals 3.3 sec. CONCLUSION: Using our proposed model it is possible to estimate an optimal delay time for CTA in most patients with SAH with a determined error.

  20. Bilateral macular haemorrhages secondary to hepatitis-associated aplastic anaemia, treated with Nd:YAG laser posterior hyaloidotomy.

    2011-01-01

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

    2015-04-01

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

    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 Victoria Cui,1,2 Timur Kouliev,1 Jason Wood1 1Beijing United Family Hospital, Beijing, People's Republic of China; 2Department of Biological Sciences, Columbia University, New York, NY, USA Abstract: During air travel, passengers are exposed to unique conditions such as rapid ascent and descent that can trigger significant physiological changes. In addition, the cabins of commercial aircraft are only partially pressured to 552–632 mmHg or the equivalent terrestrial altitudes of 1,500–2,500 m (5,000–8,000 feet above sea level. While studies in high-altitude medicine have shown that all individuals experience some degree of hypoxia, cerebral edema, and increased cerebral blood flow, the neurological effects that accompany these changes are otherwise poorly understood. In this study, we report a case of acute subarachnoid hemorrhage from a ruptured cerebral aneurysm associated with travel on commercial aircraft. We then review relevant cases of neurological incidents with possible air travel-related etiology and discuss the physiological factors that may have contributed to the patient's acute subarachnoid hemorrhage. In the future, this report may serve as reference for more detailed and conservative medical guidelines and recommendations regarding air travel.

    Full Text Available A-41-year old man presented with violent thunderclap headache and a bilateral proprioceptive sensibility deficit of the upper limbs. Cerebral CT scan and MRI were negative. Lumbar puncture confirmed subarachnoid hemorrhage (SAH, but cerebral angiography was negative. Three months later, the patient presented with paraparesis, and a thorough work-up revealed a diffuse, anaplastic extramedullary C7-D10 ependymoma with meningeal carcinomatosis considered the source of hemorrhage. The patient went through a D5-D8 laminectomy, temozolomide chemotherapy, and radiotherapy. The situation remained stable for a few months. In this paper, we would like to emphasize that spinal masses should be considered in cases of SAH with negative diagnostic findings for aneurysms or arteriovenous malformation.

    2011-09-01

    Magnesium offers theoretic vascular and neuroprotective benefits for patients with subarachnoid hemorrhage. An electronic literature search was conducted to identify original research studies describing intravenous magnesium treatment in patients with SAH published in English between January 1990 and October 2010. Seventeen articles were identified and reviewed, including one phase III randomized-controlled clinical trial and six phase II randomized-controlled trials. Study quality was low for most of the included studies, with the phase III trial considered to be of moderate quality. Due to inconsistently reported benefits and the occurrence of side effects, phase II data suggested that intravenous magnesium for SAH provided either no overall net benefit or uncertain trade-offs. Benefit was likewise not supported in the single phase III clinical trial. PMID:21748496

    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.

    Massive uncontrolled haemorrhage after childbirth is the leading cause of maternal death in developing countries. Postpartum haemorrhage is traditionally defined as blood loss of more than 500 ml after vaginal delivery and more than 1000 ml after caesarean section, but intraoperative estimation of blood loss is inaccurate. Uterine atony alone accounts for 75 - 90% of PPH. To estimate the effectiveness and safety of B-Lynch brace Suture in the management of primary postpartum haemorrhage (PPH). (author)

    Full Text Available The objective of the study is to investigate the anti-snake venom activities of a local plant, Hibiscus aethiopicus L. The H. aethiopicus was dried and extracted with ethanol. Different assays were performed according to standard techniques, to evaluate the plant’s acute toxicity and its antivenom activities. The results of evaluating the systemic acute toxicity of the H. aethiopicus extract using “oral and intra-peritoneal” route were normal even at the highest dose (24 g/kg tested. All guinea pigs (n=3 when treated with venoms E. c. sochureki (75 μg alone induced acute skin haemorrhage. In contrast, all guinea pigs (n=18 treated with both venom and the plant extract at a concentration between 500 and 1000 mg/kg showed no signs of haemorrhage. Moreover, all guinea pigs (n=18 treated with venom and the plant extract below 400 mg/kg showed acute skin haemorrhage. All guinea pigs treated with venom E. c. sochureki (75 μg alone induced acute skin haemorrhage after both 24 and 32 hours. In contrast, all guinea pigs treated with both venom and the plant extract (administered independently at concentrations between 500 and 1000 mg/kg showed no signs of haemorrhage after 32 hours. However, after 24 hours all tested guinea pigs showed less inhibition (<60% compared to that obtained after 32 hours. The outcome of this study reflects that the extract of H. aethiopicus plant may contain an endogenous inhibitor of venom induced local haemorrhage.

    OBJECTIVE Benign enlargement of the subarachnoid spaces (BESS) is a common finding on imaging studies indicated by macrocephaly in infancy. This finding has been associated with the presence of subdural fluid collections that are sometimes construed as suggestive of abusive head injury. The prevalence of BESS among infants with macrocephaly and the prevalence of subdural collections among infants with BESS are both poorly defined. The goal of this study was to determine the relative frequencies of BESS, hydrocephalus, and subdural collections in a large consecutive series of imaging studies performed for macrocephaly and to determine the prevalence of subdural fluid collections among patients with BESS. METHODS A text search of radiology requisitions identified studies performed for macrocephaly in patients ≤ 2 years of age. Studies of patients with hydrocephalus or acute trauma were excluded. Studies that demonstrated hydrocephalus or chronic subdural hematoma not previously recognized but responsible for macrocephaly were noted but not investigated further. The remaining studies were reviewed for the presence of incidental subdural collections and for measurement of the depth of the subarachnoid space. A 3-point scale was used to grade BESS: Grade 0, race, sex, or insurance status with subdural collections. Patients with BESS had larger head circumference Z-scores, but there was no association of head circumference or age with subdural collections. Interrater reliability in the diagnosis and grading of BESS was only fair. CONCLUSIONS The current study confirms the association of BESS with incidental subdural collections and suggests that greater depth of the subarachnoid space is associated with increased prevalence of such collections. These observations support the theory that infants with BESS have a predisposition to subdural collections on an anatomical basis. Incidental subdural collections in the setting of BESS are not necessarily indicative of abusive

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.

    Objective: To determine the practice of transfusion of blood and blood products in cases of postpartum haemorrhage, at a tertiary referral center. Methods: A retrospective study was conducted where medical records were reviewed for women, who either delivered or were admitted in labour suite with diagnosis of postpartum haemorrhage. The study period extended from Jan 2008 to Oct 2009. During a period of 22 months, records were reviewed for transfusion of blood and blood products in above group of women. Data were analyzed for descriptive statistics. Results: During the study period, a total of 4744 patients were admitted in the labour suite. A total of 113 (2.36%) women were diagnosed with Post partum haemorrhage. Uterine atony was the commonest cause of PPH, followed by genital tract trauma. A total of 81(71%) women received transfusion of blood and blood components (1.6%). The mean blood loss was 1088 ml (+- 584ml). Transfusion of blood and blood component therapy was significantly more in women who underwent caesarean section, compared to those women who delivered vaginally. There was one case of acute tubular necrosis due to PPH, and seven maternal deaths. The mean hospital stay was of +- 3 days. Conclusion: In this hospital based study, the prevalence of PPH was 2.36 +- %, and the rate of transfusion of blood and blood products was 1.6%.

    1984-07-01

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

    To evaluate the yield of digital subtraction angiography (DSA) and repeated follow-up imaging in patients with initial pattern of perimesencephalic subarachnoid hemorrhage (PSAH) and negative computed tomography angiography (CTA) in excluding an underlying aneurysm. We conducted a retrospective analysis of all nontraumatic SAH who underwent a DSA between January 2006 and January 2010 and selected those with a PSAH pattern on CT done within 72 h from ictus. All CTAs were performed with a 64-section multidetector row CT scanner, and findings were compared with DSA and to follow-up imaging. Forty-nine patients with initial PSAH pattern and negative CTA who underwent subsequent DSA were identified. Six patients were excluded because CTA was not available in hospitals or 72 h after ictus. Only one patient (2.4%) had a false negative CTA with a 1-mm left ICA aneurysm seen on DSA, considered not to be the source of hemorrhage. An average of 2.0 ± 1.2 follow-up exams per patient (range 0-5) revealed no source of bleeding. One patient had a procedure-related transient complication, but evolved with no sequels. In patients with PSAH, CTA is reliable for ruling out an underlying aneurysm. DSA and, especially, further follow-up imaging have no increased diagnostic yield compared to initial negative CTA.

    Head injury has been the leading cause of death and disability in people younger than 40 years and the incidence is rising continuously. Anticipation of the pathological consequences of post-traumatic subarachnoid hemorrhage (tSAH) and an outcome-oriented management are very important in these cases. To encounter the complications pertaining to traumatic brain injury (TBI) and tSAH, various classifications have been proposed and goal-oriented screening strategies have been offered. The role of serial computed tomography (CT) scans, perfusion studies, transcranial Doppler, magnetic resonance imaging (MRI), and angiographic studies as diagnostic tools, has been described. Recently, MRI fluid-attenuated inversion recovery (FLAIR), gradient reversal echo (GRE), and susceptibility weighted imaging (SWI) have emerged as excellent complimentary MRI sequences, and the authors of this article have evaluated their role in the diagnosis and prognostication of patients with tSAH. Numerous studies have been conducted on the various complications associated with tSAH such as vasospasm, hydrocephalus, and electrolyte disturbances and their management. This article discusses these aspects of tSAH and their management nuances. PMID:26954974

    Full Text Available BACKGROUND: Grading of patients with aneurysmal subarachnoid hemorrhage (aSAH is often confounded by seizure, hydrocephalus or sedation and the prediction of prognosis remains difficult. Recently, copeptin has been identified as a serum marker for outcomes in acute ischemic stroke and intracerebral hemorrhage (ICH. We investigated whether copeptin might serve as a marker for severity and prognosis in aSAH. METHODS: Eighteen consecutive patients with aSAH had plasma copeptin levels measured with a validated chemiluminescence sandwich immunoassay. The primary endpoint was the association of copeptin levels at admission with the World Federation of Neurological Surgeons (WFNS grade score after resuscitation. Levels of copeptin were compared across clinical and radiological scores as well as between patients with ICH, intraventricular hemorrhage, hydrocephalus, vasospasm and ischemia. RESULTS: Copeptin levels were significantly associated with the severity of aSAH measured by WFNS grade (P = 0.006, the amount of subarachnoid blood (P = 0.03 and the occurrence of ICH (P = 0.02. There was also a trend between copeptin levels and functional clinical outcome at 6-months (P = 0.054. No other clinical outcomes showed any statistically significant association. CONCLUSIONS: Copeptin may indicate clinical severity of the initial bleeding and may therefore help in guiding treatment decisions in the setting of aSAH. These initial results show that copeptin might also have prognostic value for clinical outcome in aSAH.

    Delayed cerebral ischemia is the most feared cause of secondary injury progression after subarachnoid hemorrhage. Initially thought to be a direct consequence of large artery spasm and territorial ischemia, recent data suggests that delayed cerebral ischemia represents multiple concurrent and synergistic mechanisms, including microcirculatory dysfunction, inflammation, and microthrombosis. Among these mechanisms, spreading depolarizations (SDs) are arguably the most elusive and underappreciated in the clinical setting. Although SDs have been experimentally detected and examined since the late 1970s, their widespread occurrence in human brain was not unequivocally demonstrated until relatively recently. We now know that SDs occur with very high incidence in human brain after ischemic or hemorrhagic stroke and trauma, and worsen outcomes by increasing metabolic demand, decreasing blood supply, predisposing to seizure activity, and possibly worsening brain edema. In this review, we discuss the causes and consequences of SDs in injured brain. Although much of our mechanistic knowledge comes from experimental models of focal cerebral ischemia, clinical data suggest that the same principles apply regardless of the mode of injury (i.e., ischemia, hemorrhage, or trauma). The hope is that a better fundamental understanding of SDs will lead to novel therapeutic interventions to prevent SD occurrence and its adverse consequences contributing to injury progression in subarachnoid hemorrhage and other forms of acute brain injury.

    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.

    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).

  9. Filoviral haemorrhagic fevers: A threat to Zambia?

    2012-06-01

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

    Aneurysmal subarachnoid hemorrhage (SAH) can lead to devastating outcomes including vasospasm, cognitive decline, and even death. Currently, treatment options are limited for this potentially life threatening injury. Recent evidence suggests that neuroinflammation plays a critical role in injury expansion and brain damage. Red blood cell breakdown products can lead to the release of inflammatory cytokines that trigger vasospasm and tissue injury. Preclinical models have been used successfully to improve understanding about neuroinflammation following aneurysmal rupture. The focus of this review is to provide an overview of how neuroinflammation relates to secondary outcomes such as vasospasm after aneurysmal rupture and to critically discuss pharmaceutical agents that warrant further investigation for the treatment of subarachnoid hemorrhage. We provide a concise overview of the neuroinflammatory pathways that are upregulated following aneurysmal rupture and how these pathways correlate to long-term outcomes. Treatment of aneurysm rupture is limited and few pharmaceutical drugs are available. Through improved understanding of biochemical mechanisms of injury, novel treatment solutions are being developed that target neuroinflammation. In the final sections of this review, we highlight a few of these novel treatment approaches and emphasize why targeting neuroinflammation following aneurysmal subarachnoid hemorrhage may improve patient care. We encourage ongoing research into the pathophysiology of aneurysmal subarachnoid hemorrhage, especially in regards to neuroinflammatory cascades and the translation to randomized clinical trials.

    Peter Lackner

    Full Text Available Chronic communicating hydrocephalus is a significant health problem affecting up to 20% of survivors of spontaneous subarachnoid hemorrhage (SAH. The development of new treatment strategies is hampered by the lack of well characterized disease models. This study investigated the incidence of chronic hydrocephalus by evaluating the temporal profile of intracranial pressure (ICP elevation after SAH, induced by endovascular perforation in rats. Twenty-five adult male Sprague-Dawley rats (260-320 g were subjected to either endovascular perforation or sham surgery. Five animals died after SAH induction. At 7, 14 and 21 days after surgery ICP was measured by stereotaxic puncture of the cisterna magna in SAH (n=10 and SHAM (n=10 animals. On day 21 T-maze test was performed and the number of alterations and latency to decision was recorded. On day 23, samples were processed for histological analyses. The relative ventricle area was evaluated in coronal Nissl stained sections. On day 7 after surgery all animals showed normal ICP. The absolute ICP values were significantly higher in SAH compared to SHAM animals on day 21 (8.26±4.53 mmHg versus 4.38±0.95 mmHg but not on day 14. Observing an ICP of 10 mmHg as cut-off, 3 animals showed elevated ICP on day 14 and another animal on day 21. The overall incidence of ICP elevation was 40% in SAH animals. On day 21, results of T-maze testing were significantly correlated with ICP values, i.e. animals with elevated ICP showed a lower number of alterations and a delayed decision. Histology yielded a significantly higher (3.59 fold increased relative ventricle area in SAH animals with ICP elevation compared to SAH animals without ICP elevation. In conclusion, the current study shows that experimental SAH leads to chronic hydrocephalus, which is associated with ICP elevation, behavioral alterations and ventricular dilation in about 40% of SAH animals.

We report two cases of GMIVH in fetuses of 36 weeks gestation, clearly demonstrated by antenatal MRI. In both cases progressive ventriculomegaly was observed, and ventriculoperitoneal shunts were placed at 19 and 6 months of age, respectively. Prenatal GMIVH may be a cause of congenital hydrocephalus, for which no aetiology has yet been found. (orig.)

  1. Postpartum haemorrhage: a preventable cause of maternal mortality

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

  3. Management of subarachnoid hemorrhage classified grade V. Possibility of intravascular treatment

    International Nuclear Information System (INIS)

    Management outcomes in poor-grade patients (World Federation of Neurological Surgeons Committee on a Universal Subarachnoid Hemorrhage Grading Scale Grade V) with ruptured cerebral aneurysms have historically been unsatisfactory. In the present study, we examined the possibility of intravascular treatment for ruptured aneurysm detected by 3-Dimensional CT angiography (3D-CTA) in poor-grade SAH patients. From April 1997 to July 2000, 3D-CTA was performed on 54 of 73 patients admitted with Grade V subarachnoid hemorrhage (SAH). Excluding 3 patients who underwent emergency surgery for ruptured aneurysms and intracerebral hematomas, CT findings from the remaining 51 patients were analyzed. The study included 23 men and 28 women, ranging in age from 28 to 91 with an average age of 63.6. The patients' initial scores on the Glasgow Coma Scale upon admission were 3 in 36 patients (including 19 patients who had undergone cardio-pulmonary arrest), 4 in 11 patients, 5 in 2 patients, and 6 in 2 patients. Ruptured aneurysms responsible for SAH were clearly delineated in 41 aneurysms from 39 patients, with 32 aneurysms in the anterior circulation and 9 in the posterior circulation. Patients with Glasgow Coma Scale of 4 or higher whose score did not progressively decrease for 12 hours after symptom onset were considered for intravascular treatment. In our study, 4 of 39 patients (10.3%) met these criteria. Glasgow Outcome Scale results were good recovery in 1 case, moderate disability in 1 case, severe disability in 1 case, and death in the remaining 48 cases. These results suggest that the management course for poor-grade (WFNS Grade V) SAH patients who retain brain stem reflexes contain the following: identification of aneurysms by 3D-CTA, maintenance of adequate sedation and external drainage to treat acute hydrocephalus, continued minimum 12-hour observation, monitoring levels of consciousness where possible, and consideration of aggressive therapy including intravascular

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

    We report subarachnoid hemorrhage associated with cyclosporine A (CSA) neurotoxicity after bone-marrow transplantation for chronic myelogenous leukemia. CT showed occipital subarachnoid hemorrhage. MRI confirmed this, and demonstrated cortical and subcortical edema in the posterior temporal, occipital, and posterior frontal lobes bilaterally, which was typical of CSA neurotoxicity. Recognition of CSA neurotoxicity as the cause of the subarachnoid hemorrhage obviated angiographic investigation. After cessation of cyclosporine therapy, the cortical and subcortical edema resolved on follow-up MRI with some residual blood products in the subarachnoid space. (orig.)

    International Nuclear Information System (INIS)

    The patient was a 66-year-old man. He lost consciousness as a result of a third subarachnoid hemorrhage attack. On neurological examination, he was found to be comatose and to have no spontaneous respiration. A mydriasis was noticed on both eyes. Bilateral retinal bleeding was also observed, with the bleeding of the left side more severe than that of the right side. After his death, his brain and eyes were examined by means of a CT scan. The CT films showed a severe subarachnoid hemorrhage and ventricular hematoma. The thin-sliced CT films showed left retinal bleeding. Retinal bleeding may be caused by a subarachnoid hemorrhage. Usually we make a sketch of the retinal bleeding on the basis of a doctor's report. A photo of an optic fundus is a good record; however, taking a photo is troublesome for severely ill patients. The CT finding of retinal bleeding is gross, but a CT image is one good way to record retinal bleeding. (author)

  13. Bilateral adrenal haemorrhage secondary to intra-abdominal sepsis: a case report.

    LENUS (Irish Health Repository)

    Egan, Aoife M

    2012-01-31

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

  15. Sequential changes in cerebral blood flow and outcome in patients with subarachnoid hemorrhage

    International Nuclear Information System (INIS)

    The sequential cerebral blood flow (CBF) and the CBF response to acetazolamide (AZ; 1 g I.V.; cerebrovascular reserve capacity rate (CRCR)) were studied within four days after the initial subarachnoid hemorrhage (SAH) in 42 patients. Stable xenon-enhanced computed tomography (xenon-CT) was used. The mean global CBF of the patients was reduced in accordance with the severity of the neurological grade (Hunt and Kosnik (H-K) grading). In the subacute stage of SAH, the CBF had the tendency to decline in patients with H-K grades I and II. By comparison, in the chronic stage there was an increase in the CBF in all patients. On the other hand, the CBF response to AZ declined in accordance with the severity of neurological grading. The CRCR at the acute phase of SAH was significantly diminished in patients who had a poor outcome as compared to that of individuals who had a good outcome. Questions pertaining to the usefulness of the CBF response to AZ in the acute phase of SAH are being addressed in the present report. (author)

    Full Text Available Introduction & Objective: Electrolyte disturbances are frequently observed during the acute period after spontaneous subarachnoid hemorrhage (SAH. Hyponatremia and hypernatremia are the most common electrolyte disturbance in acute period of disease, and these disturbances may worsen cerebral edema and mass effect. We performed this study to determine the prognostic significance of serum sodium concentration abnormalities.Materials & Methods: This study was performed as prospective analytic cross sectional in Kashani and Alzahra Hospitals of Isfahan during 2003-2004. The presence of hypernatremia (serum sodium concentration of>145m mol/L and hyponatremia (serum sodium concentration of<135mmol/l was determined with serum sodium measurements at admission and 3, 6 and 9 days after SAH, then the effects of hypernatremia and hyponatremia on three-month outcomes were analyzed after adjustment for age, sex, preexiting HTN , admission GCS score, initial mean arterial pressure and finding of Brain CT Scan and Brain angiography. Patients with symptomatic vasospasm were excluded.Results: The analysis of data showed that from 100 participated patients in this study 18% developed hypernatremia and 42% developed hyponatremria. Hypernatemia was significantly assiociated with poor outcomes compared with hyponatremia (odds ratio, 2.63- CI 95% . Conclusion: Hyponatremia seems to be more common than hypernatremia after SAH. Hypernatrenia after SAH associted with poor outcome and this association is independet of previously identified outcome predictors, including age, sex, admission GCS Score, and X.Ray finding.

    Background Intracranial haemorrhage is a serious and potentially fatal complication of oral anticoagulant therapy. Prothrombin complex concentrates can substantially shorten the time needed to reverse the effects of oral anticoagulants. The aim of this study was to determine the efficacy and safety of a prothrombin complex concentrate for rapid reversal of oral anticoagulant therapy in patients with intracranial haemorrhage. Methods Patients receiving oral anticoagulant therapy and suffering from acute intracranial haemorrhage were eligible for this prospective cohort study if their International Normalised Ratio (INR) was higher than or equal to 2.0. The prothrombin complex concentrate was infused at doses of 35–50 IU/kg, stratified according to the initial INR. Results Forty-six patients (25 males; mean age: 75 years; range 38–92 years) were enrolled. The median INR at presentation was 3.5 (range, 2–9). At 30 minutes after administration of the prothrombin complex concentrate, the median INR was 1.3 (range, 0.9–3), and the INR then declined to less than or equal to 1.5 in 75% of patients. The benefit of the prothrombin complex concentrate was maintained for a long time, since the median INR remained lower than or equal to 1.5 (median, 1.16; range, 0.9–2.2) at 96% of all post-infusion time-points up to 96 hours. No thrombotic complications or significant adverse events were observed during hospitalisation; six patients (13%) died, but none of these deaths was judged to be related to administration of the prothrombin complex concentrate. Conclusions Prothrombin complex concentrates are an effective, rapid and safe treatment for the urgent reversal of oral anticoagulation in patients with intracranial haemorrhage. Broader use of prothrombin complex concentrates in this clinical setting appears to be appropriate. PMID:21251465

    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.

    International Nuclear Information System (INIS)

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

    Our previous studies demonstrated that propofol protects rat brain against focal cerebral ischemia. However, whether propofol attenuates early brain injury after subarachnoid hemorrhage in rats remains unknown until now. The present study was performed to evaluate the effect of propofol on early brain injury after subarachnoid hemorrhage in rats and further explore the potential mechanisms. Sprague-Dawley rats underwent subarachnoid hemorrhage (SAH) by endovascular perforation then received treatment with propofol (10 or 50 mg/kg) or vehicle after 2 and 12 h of SAH. SAH grading, neurological scores, brain water content, Evans blue extravasation, the myeloperoxidase activity, and malondialdehyde (MDA) content were measured 24 h after SAH. Expression of nuclear factor erythroid-related factor 2 (Nrf2), nuclear factor-kappa B (NF-κB) p65, and aquaporin 4 (AQP4) expression in rat brain were detected by Western blot. Expression of cyclooxygenase-2 (COX-2) and matrix metalloproteinase-9 (MMP-9) were determined by reverse transcription-polymerase chain reaction (RT-PCR). Expressions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were assessed by ELISA. Neurological scores, brain water content, Evans blue extravasation, the myeloperoxidase activity, and MDA content were significantly reduced by propofol. Furthermore, expression of Nrf2 in rat brain was upregulated by propofol, and expression of NF-κB p65, AQP4, COX-2, MMP-9, TNF-α, and IL-1β in rat brain were attenuated by propofol. Our results demonstrated that propofol improves neurological scores, reduces brain edema, blood-brain barrier (BBB) permeability, inflammatory reaction, and lipid peroxidation in rats of SAH. Propofol exerts neuroprotection against SAH-induced early brain injury, which might be associated with the inhibition of inflammation and lipid peroxidation. PMID:26342279

    Full Text Available Neurocysticercosis is the most common central nervous system helminthic infection in humans. We hereby present a case combining two rare manifestations of neurocysticercosis: the subarachnoid and intraventricular forms. The patient presented with hydrocephalus and neurologic deficits and although endoscopic removal of the cysts and two cycles of postoperative cysticidal drugs resulted in resolution of symptoms, they later recurred. Ventriculoperitoneal shunt placement and a further cycle of albendazole plus dexamethasone led to substantial clinical improvement. Extraparenchymal neurocysticercosis may be challenging to diagnose and treat and is usually associated with a poorer prognosis. Clinicians should be aware of this condition.

    Cerebral vasospasm (CVS) is a common and severe complication of aneurysmal subarachnoid hemorrhage (aSAH). Despite the improvement in treatment of aSAH, CVS complicating aSAH has remained the main cause of death. CVS begins most often on the third day after the ictal event and reaches the maximum on the 5th–7th postictal days. Several therapeutic modalities have been employed to prevent or reverse CVS. The aim of this review is to summate all the available drug treatment modalities for vasospasm.

    2013-01-01

    Full Text Available Delayed cerebral vasospasm is a significant cause of morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH. While the cellular mechanisms underlying vasospasm remain unclear, it is believed that inflammation may play a critical role in vasospasm. Matrix metalloproteinasees (MMPs are a family of extracellular and membrane-bound proteases capable of degrading the blood-rain barrier (BBB. As such, MMP upregulation following SAH may result in a proinflammatory extravascular environment capable of inciting delayed cerebral vasospasm. This paper presents an overview of MMPs and describes existing data pertinent to delayed cerebral vasospasm.

    Subarachnoid hemorrhage (SAH) represents a considerable health problem with an incidence of 6–7 per 100.000 individuals per year in Western society. We investigated the long-term consequences of SAH on behavior, neuroinflammation and gray- and white-matter damage using an endovascular puncture model in Wistar rats. Rats were divided into a mild or severe SAH group based on their acute neurological score at 24 h post-SAH. The degree of hemorrhage determined in post-mortem brains at 48 h strongly correlated with the acute neurological score. Severe SAH induced increased TNF-α, IL-1β, IL-10, MCP-1, MIP2, CINC-1 mRNA expression and cortical neutrophil influx at 48 h post-insult. Neuroinflammation after SAH was very long-lasting and still present at day 21 as determined by Iba-1 staining (microglia/macrophages) and GFAP (astrocytes). Long-term neuroinflammation was strongly associated with the degree of severity of SAH. Cerebral damage to gray- and white-matter was visualized by immunohistochemistry for MAP2 and MBP at 21 days after SAH. Severe SAH induced significant gray- and white-matter damage. MAP2 loss at day 21 correlated significantly with the acute neurological score determined at 24 h post-SAH. Sensorimotor behavior, determined by the adhesive removal task and von Frey test, was affected after severe SAH at day 21. In conclusion, we are the first to show that SAH induces ongoing cortical inflammation. Moreover, SAH induces mainly cortical long-term brain damage, which is associated with long-term sensorimotor damage. PMID:24603553

A retrospective review analysing tonsillectomy method, the rate secondary haemorrhage, the grade of operating surgeon. A χ(2) analysis was used to determine the statistical difference between the haemorrhage rates of different tonsillectomy methods. One thousand three hundred and thirty-six tonsillectomies were performed during this period by four different methods: 615 by cold steel dissection, 582 by Coblation, 32 by bipolar dissection and 107 by Helica thermal coagulation. 621 tonsillectomies were performed by Consultant grade and middle grades performed 693 operations. 124 patients (9.3 %) were readmitted with haemorrhage. The secondary haemorrhage requiring surgery for controlling bleeding for cold steel dissection method was 1.5 % compared to 6.7 % for coblation method (P tonsillectomy haemorrhage rate of 5.5 % and middle grades had a rate of 3.7 %. 86.5 % of the patients were already on routine prophylactic oral antibiotics at the time of presentation with haemorrhage needing surgical arrest and 13.5 % were not on antibiotics (P coblation and cold steel dissection methods.

    2004-01-01

    The incidence of subarachnoid hemorrhage (SAH) is stable, at around 6 per 100 000 per annum, but higher in Japan and Finland. Any apparent decrease is attributable to a higher rate of computed tomography (CT) scanning, by which other haemorrhagic conditions are excluded. Most patients are below 60 years of age. Risk factors are similar to those for stroke in general; genetic factors operate in a minority. Case fatality is around 50% overall (including prehospital deaths); one third of survivors remain dependent. Sudden, explosive headache is a cardinal but non-specific feature in the diagnosis of SAH: in general practice the cause is innocuous in 9 out of 10 patients in whom this is the only symptom. CT scanning is mandatory in all, to be followed by (delayed) lumbar puncture if CT is negative. The cause of SAH is a ruptured aneurysm in 85%, non-aneurysmal perimesencephalic hemorrhage (with excellent prognosis) in 10%, and a variety of rare conditions in 5%. Catheter angiography for detecting aneurysms is gradually being replaced by CT or MR angiography. A poor clinical condition on admission may be caused by a remediable complication of the initial bleed or a recurrent hemorrhage: intracranial haematoma, acute hydrocephalus, or global brain ischemia. Occlusion of the aneurysm effectively prevents rebleeding, but there is a dearth of controlled trials assessing the relative benefits of early operation (within three days) versus late operation (day 10-12). Endovascular occlusion is now clearly preferable to operation if the location and structure of the aneurysm make this feasible. Antifibrinolytic drugs reduce the risk of rebleeding but do not improve overall outcome. The risk of delayed cerebral ischemia can be decreased by oral administration of nimodipine; other measures, with some support from observational studies,are a liberal supply of fluids and avoidance of antihypertensive drugs. Once ischemia has occurred treatment regimens such as a combination of

    An aneurysmal subarachnoid hemorrhage (aSAH) carries a high disability burden. The true impact of rurality as a predictor of outcome severity is unknown.

    Full Text Available Biomarkers for neurodegeneration could be early prognostic measures of brain damage and dysfunction in aneurysmal subarachnoid hemorrhage (aSAH with clinical and medical applications. Recently, we developed a new panel of neurodegeneration biomarkers, and report here on their relationships with pathophysiological complications and outcomes following severe aSAH. Fourteen patients provided serial cerebrospinal fluid samples for up to 10 days and were evaluated by ultrasonography, angiography, magnetic resonance imaging, and clinical examination. Functional outcomes were assessed at hospital discharge and 6-9 months thereafter. Eight biomarkers for acute brain damage were quantified: calpain-derived α-spectrin N- and C-terminal fragments (CCSntf and CCSctf, hypophosphorylated neurofilament H,14-3-3 β and ζ, ubiquitin C-terminal hydrolase L1, neuron-specific enolase, and S100β. All 8 biomarkers rose up to 100-fold in a subset of patients. Better than any single biomarker, a set of 6 correlated significantly with cerebral vasospasm, brain infarction, and poor outcome. Furthermore, CSF levels of 14-3-3β, CCSntf, and NSE were early predictors of subsequent moderate-to-severe vasospasm. These data provide evidence that a panel of neurodegeneration biomarkers may predict lasting brain dysfunction and the pathophysiological processes that lead to it following aSAH. The panel may be valuable as surrogate endpoints for controlled clinical evaluation of treatment interventions and for guiding aSAH patient care.

    2005-02-01

    We have reviewed initial diagnostic features, treatment, and outcome in 29 patients with acute subarachnoid hemorrhage due to non-traumatic vertebrobasilar artery dissection diagnosed in our hospital between 1993 and 2003. The dissections occurred in the vertebral artery in 19 patients, the posterior inferior cerebellar artery (PICA) in two patients, the basilar artery in four patients, and in the vertebral artery extending into the PICA in four patients. A pseudoaneurysm was found in 20 patients. Clinical manifestations typically included sudden onset of moderate to severe headache, nuchal rigidity, and drowsiness. Fourteen patients were treated conservatively. Fifteen patients underwent endovascular treatment with either parent artery occlusion (13 patients) or aneurysmal coil occlusion with preservation of the parent artery (2 patients). Re-bleeding occurred within 12 days and before treatment in nine patients. Eight of these had a pseudoaneurysm. No patient bled after endovascular treatment. Poor grade and early re-bleeding were associated with less favorable outcome. Outcome at 6 months did not differ significantly between endovascular and conservative treatment. Altogether, good recovery was achieved for 16 patients, moderate disability was seen in one, severe disability in four, and eight patients (27%) died. The absence of bleeding subsequent to endovascular treatment in this study suggests that endovascular treatment may be a rational approach in these patients at high risk of re-bleeding, especially those with a pseudoaneurysm.

    The most common neurological injuries associated with roller coaster rides are subdural hematoma and cervical artery dissection. We report two cases of roller-coaster associated subarachnoid hemorrhage (SAH). A 40-year-old healthy man developed a strong, holocephalic headache during a roller coaster ride. SAH Hunt & Hess grade II and Fisher grade 3 was diagnosed. An underlying aneurysm of the anterior communicating artery was successfully treated with coil embolization. A 41-year-old female (smoker, otherwise healthy) experienced a sudden, strong headache and diplopia during a roller coaster ride. A perimesencephalic SAH (Hunt & Hess grade II, Fisher grade 3) was disclosed by a CT scan. No aneurysm was detected on angiography. Both patients were discharged without neurological disability. In conclusion, SAH is a rare but relevant differential diagnosis in cases of acute headache during roller coaster rides. Both aneurysmal and non-aneurysmal perimesencephalic SAH can occur. A combination of mechanical factors and excessive blood pressure rises in vulnerable persons is discussed. PMID:22177088

    Previous studies have shown that mitochondrial Ca(2+) is undertaken by mitochondrial calcium uniporter (MCU), and its accumulation is associated with the development of many diseases. However, little was known about the role of MCU in early brain injury (EBI) after subarachnoid hemorrhage (SAH). MCU can be opened by spermine under a physiological condition and inhibited by ruthenium red (RR). Herein, we investigated the effects of RR and spermine to reveal the role of MCU in SAH animal model. The data obtained with biochemical and histological assays showed that mitochondrial Ca(2+) concentration was significantly increased in the temporal cortex of rats 1, 2, and 3 days after SAH, consistent with constant high levels of cellular Ca(2+) concentration. In agreement with the observation in the acute phase, SAH rats showed an obvious increase of reactive oxygen species (ROS) level and decrease of ATP production. Blockage of MCU prevented Ca(2+) accumulation, abated the level of oxidative stress, and improved the energy supply. Translocation of cytochrome c, increased cleaved caspase-3, and a large amount of apoptotic cells after SAH were reversed by RR administration. Surprisingly, exogenous spermine did not increase cellular Ca(2+) concentration, but lessened the Ca(2+) accumulation after SAH to benefit the rats. Taken together, our results demonstrated that blockage of MCU or prevention of Ca(2+) accumulation after SAH is essential in EBI after SAH. These findings suggest that MCU is considered to be a therapeutic target for patients suffering from SAH.

    Full Text Available Cerebral venous thrombosis has a wide spectrum of clinical manifestations that may mimic many other neurological disorders and lead to frequent misdiagnoses or delay in diagnosis. The most frequent symptoms and signs are headache, seizures, focal deficits, and papilledema. A number of rare atypical manifestations have been described. Cerebral venous thrombosis may present with an isolated intracranial hypertension type picture, thunderclap headache, attacks of migraine with aura, isolated psychiatric disturbances, pulsatile tinnitus, isolated or multiple cranial nerve involvement, and occasionally as subarachnoid hemorrhage (SAH or transient ischemic attack. Our patient presented with thunderclap headache and transient ischemic attack like episode with obvious SAH on CT scan. Acute SAH suggests the presence of a vascular lesion, such as ruptured aneurysm, and CVT is not generally considered in the diagnostic workup of SAH. The case emphasizes the importance of cerebral venous study in nonaneurysmal cases of SAH. It is important to have a high index of suspicion in such atypical cases to avoid delay in diagnosis.

    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.

  13. Detection and localization of internal haemorrhaging using electrical bioimpedance

    International Nuclear Information System (INIS)

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

    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.

  1. Trans-anastomotic porto-portal varices in patients with gastrointestinal haemorrhage

    Energy Technology Data Exchange (ETDEWEB)

    Mitchell, A.W.M.; Jackson, J.E

    2000-03-01

    AIM: Porto-portal varices are commonly seen in patients with segmental extra-hepatic portal hypertension and develop to provide a collateral circulation around an area of portal venous obstruction. It is not well recognized that such communications may also develop across surgical anastomoses and be the source of gastrointestinal haemorrhage. The possible mode of development of such communications has not been previously discussed. MATERIALS AND METHODS: Over a 3-year period between 1995 and 1998, porto-portal varices were demonstrated across surgical anastomoses in four patients who were referred for the investigation of acute (two), acute-on-chronic (one) and chronic gastrointestinal bleeding (one). Their medical notes and the findings at angiography were reviewed. RESULTS: Three patients had segmental portal hypertension due to extra-hepatic portal vein (one) or superior mesenteric vein (two) stenosis/occlusion. One patient had mild portal hypertension due to hepatic fibrosis secondary to congenital biliary atresia. At angiography all patients were shown to have varices crossing previous surgical anastomoses. These varices were presumed to be the cause of bleeding in three of the four patients; the site of bleeding in the fourth individual was not determined. CONCLUSIONS: Trans-anastomotic porto-portal varices are rare. They develop in the presence of extra-hepatic portal hypertension and presumably arise within peri-anastomotic inflammatory tissue. Such varices may be difficult to manage and their prognosis is poor when bleeding occurs. Mitchell, A.W.M., Jackson, J.E. (2000)

    Neurocysticercosis is the most frequent parasitic disease of the central nervous system. It is caused by the larvae of Taenia solium, which can affect different anatomical sites. In Spain there is an increasing prevalence mainly due to immigration from endemic areas. The extraparenchymal forms are less common, but more serious because they usually develop complications. Neuroimaging plays a major role in the diagnosis and follow-up of this disease, supported by serology and a compatible clinical and epidemiological context. First-line treatments are cysticidal drugs such as albendazole and praziquantel, usually coadministered with corticosteroids, and in some cases surgery is indicated. We here report a case of neurocysticercosis with simultaneous intraventricular and giant racemose subarachnoid involvement.

    We reported a case of peduncular hallucination after aneurysmal subarachnoid hemorrhage (SAH). The patient underwent endovascular embolization of an intracranial aneurysm using the Guglielmi detachable coils (GDCs) 9 days after SAH. On the 11th day, she reported visual hallucination: a maggot was on the ceiling, or a soldier who wore green clothes was standing by a locker. The hallucination was vivid, well-formed and associated with insomnia, suggesting peduncular hallucination. A computed tomographic (CT) scan revealed small infarctions of right frontal lobe, which were not responsible for the visual hallucination. Hyperdynamic therapy relieved the visual hallucination 23 days after SAH. It was conceivable that vasospasm was the cause of the infarction and visual hallucination. Only 4 cases with peduncular hallucination after SAH were reported in conjunction with vasospasm. The symptom may be concealed by disturbance of consciousness. Visual hallucination should be considered as a sign of cerebral vasospasm, and an appropriate treatment should be done at right time. PMID:10065463

    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...

    Full Text Available La hemorragia es una de las causas más frecuentes y potencialmente más graves en la consulta de urgencias durante la gestación. 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.

  18. Management of symptomatic thrombocytopenia associated with dengue haemorrhagic fever

    International Nuclear Information System (INIS)

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

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

    Full Text Available Background: Hypomagnesemia is commonly encountered in patients with a wide variety of diseases including subarachnoid hemorrhage (SAH, cardiovascular emergencies, head trauma, migraine attacks, seizure and preeclampsia. It seems to be associated with a poor clinical outcome. This study considers the prevalence and temporal distribution of hypomagnesemia after aneurysmal SAH and its correlation with the severity of SAH, delayed cerebral ischemia (DCI as well as the neurological outcome after a period of three months.Methods: Between 2003 and 2008, 60 patients were admitted to the emergency ward of Imam Khomeini Hospital with acute SAH. Serum magnesium levels were measured during the first 72 hours, days 4-7, and second and third weeks after SAH. The three-month outcome was assessed according to the Glasgow Outcome Scale (GOS. Clinical SAH grading was performed according to the criteria of the World Federation of Neurological Surgeons (WFNS and the patients were allocated to "Good" (GOS = 4, 5 and "Poor" (GOS= 1-3 outcome groups. The prevalence of hypomagnesemia was assessed in both patient groups. Fisher exact test was used to analyze data.Results: Hypomagnesemia occurred in 22% of patients during the first 72 hours after SAH. It was associated with more prevalent DCI (p<0.05, whereas low serum magnesium levels during days 4-7 17% of patients and the second week (22% of patients after SAH were correlated with poor clinical outcome (p<0.05. No correlation was found between first 72 hour-hypomagnesemia and poor clinical outcome at three months.Conclusion: Hypomagnesemia occurs after aneurysmal SAH and it may predict the occurrence of DCI, while low serum magnesium levels during days 4-7 and within the second week of event predict poor clinical outcome at three months. Treatment of this electrolyte disturbance may have a favourable effect on the clinical outcome of patients with aneurysmal SAH.

  1. Blockage of mitochondrial calcium uniporter prevents iron accumulation in a model of experimental subarachnoid hemorrhage

    International Nuclear Information System (INIS)

    Highlights: • Iron accumulation was involved in the acute phase following SAH. • Blockage of MCU could attenuate cellular iron accumulation following SAH. • Blockage of MCU could decrease ROS generation and improve cell energy supply following SAH. • Blockage of MCU could alleviate apoptosis and brain injury following SAH. - Abstract: Previous studies have shown that iron accumulation is involved in the pathogenesis of brain injury following subarachnoid hemorrhage (SAH) and chelation of iron reduced mortality and oxidative DNA damage. We previously reported that blockage of mitochondrial calcium uniporter (MCU) provided benefit in the early brain injury after experimental SAH. This study was undertaken to identify whether blockage of MCU could ameliorate iron accumulation-associated brain injury following SAH. Therefore, we used two reagents ruthenium red (RR) and spermine (Sper) to inhibit MCU. Sprague–Dawley (SD) rats were randomly divided into four groups including sham, SAH, SAH + RR, and SAH + Sper. Biochemical analysis and histological assays were performed. The results confirmed the iron accumulation in temporal lobe after SAH. Interestingly, blockage of MCU dramatically reduced the iron accumulation in this area. The mechanism was revealed that inhibition of MCU reversed the down-regulation of iron regulatory protein (IRP) 1/2 and increase of ferritin. Iron–sulfur cluster dependent-aconitase activity was partially conserved when MCU was blocked. In consistence with this and previous report, ROS levels were notably reduced and ATP supply was rescued; levels of cleaved caspase-3 dropped; and integrity of neurons in temporal lobe was protected. Taken together, our results indicated that blockage of MCU could alleviate iron accumulation and the associated injury following SAH. These findings suggest that the alteration of calcium and iron homeostasis be coupled and MCU be considered to be a therapeutic target for patients suffering from SAH

    BACKGROUND: Recent studies have indicated that blood-brain barrier (BBB) disruption following subarachnoid hemorrhage (SAH) significantly correlates with the development of brain injury and poor prognosis of patients subjected to SAH. OBJECTIVE: To investigate both functional and structural changes related to BBB in various phases after SAH in rats through quantitative and qualitative methods.DESIGN, TIME AND SETTING: This experiment, a completely randomized design and controlled experiment, was performed at the Department of Neurosurgery, the Second Affiliated Hospital of Chongqing University of Medical Sciences from June 2006 to March 2007.MATERIALS: A total of 128 female, healthy, Sprague-Dawley rats were selected for this study. Main reagents and instruments: Evans Blue dye (Sigma Company, USA), fluorescence spectrophotometer (Shimadzu Company, Japan), and transmission electron microscope (Olympus Company, Japan). MAIN OUTCOME MEASURES: Brain tissue water content was determined by the wet-dry method. BBB permeability in the cerebral cortex was determined by Evans Blue dye and fluorescent spectrophotometer. The ultrastructural changes in BBB were observed with transmission electron microscope.RESULTS: Compared with the sham-operated group, SAH induced a significant increase in brain water content between 24 and 60 hours (F = 888.32, P 0.05). Electron microscopy demonstrated only a mild perivascular edema at 24 hours after SAH. By 36 hours, a notable perivascular edema was associated with a collapse of the capillary. Astrocytic endfeet surrounding the capillary were prominently swollen in the edematous areas. The above-mentioned abnormal ultrastructural changes in the BBB were reversed by 72 hours after SAH. No obvious morphological changes in the BBB were detected in the sham-operated rats.CONCLUSION: These results directly suggest that SAH could induce rapid changes in BBB function and structure during the acute phases of BBB breakdown. Moreover, these dynamic

    The rupture and bleeding of intracranial aneurysms is the most common cause of a spontaneous, non-traumatic subarachnoid hemorrhage (SAH). In up to 20% of these patients, no aneurysm is found, but the prognosis of these patients is known to be better than in those with aneurysms. The retrospective evaluation of the initial CT- and angiographic findings of 773 patients with spontaneous SAH, who underwent (up to three) 4-vessel DSA, brought a percentage of 12.4% with negative angiography. We found the favourable prognosis of these patients with negative angiography not only to be dependant from the distribution of the hemorrhage, with preference to perimesencephalic pattern, but the initial clinical state. 85% of our patients, who presented with perimesencephalic blood pattern and even 80% of those patients with additional intraventricular hemorrhage but the good clinical condition of Hunt-Hess I/II were discharged without neurological deficits. We recommend the obligatory 4-vessel catheter-angiography (DSA) in all patients with spontaneous SAH, independent of the blood pattern on initial CT, and one control in the presence of other than perimesencephalic subarachnoid hemorrhage, CTA might be reserved for additional controls. (orig.) [German] Die Aneurysmablutung stellt die haeufigste Ursache einer spontanen, nichttraumatischen Subarachnoidalblutung (SAB) dar, bei einem Teil dieser Patienten kann jedoch kein Aneurysma nachgewiesen werden. Die Prognose dieser Patienten ist, im Vergleich zu denen mit positivem Aneurysmabefund, deutlich guenstiger. Die retrospektive Evaluation der initialen CT- und Angiographiebefunde sowie des klinischen Verlaufs von 773 Patienten, die innerhalb der letzten 11 Jahre nach einer spontanen SAB einer 4-Gefaessangiographie (DSA) unterzogen worden waren, ergab in unserem Krankengut einen Prozentsatz von 12,4% mit endgueltig fehlendem Aneurysmanachweis, wobei bis zu 3 Kontrollangiographien durchgefuehrt worden waren.

    Full Text Available Incidence of spontaneous subarachnoid hemorrhages (SAH varies wildly across the world and seems to be low in Central and South America (4.2 per 100 000 person-years; CI 95%; 3.1-5.7. The objective of our study was to describe the characteristics of SAH and to estimate its incidence and severity in Martinique, a small French island located in the Caribbean Sea.Due to its insular nature and small captive population, Martinique is ideal for the setting up of population-based epidemiological studies with good exhaustiveness. Our study, spanning a 7 year period (2007-2013, consisted of retrospective case ascertainment with multiple overlapping methods. Crude incidence and 30 day case-fatality rates for SAH among the Martinican population were computed for the study period. Incidence and disease severity was also analyzed according to age, gender and aneurysm presence. World age-standardized incidence rates were also calculated.A total of 121 patients had a SAH during the study period, with a higher frequency of female cases (71.1% versus 28.9%, p<0.001. Patient mean age was 57.1 years (median = 55 [46-66]. An aneurysmal origin was found in 96 SAH cases (79.3%. Crude annual incidence was 4.36 per 100 000 person-years (CI 95% 2.30-6.42. World age-standardized incidence was 3.29 per 100 000 person-years (CI 95% 1.74-4.84. During the 30 days following SAH diagnosis, 29 patients died (case fatality rate: 24% (CI 95% 16.4-31.6.The incidence of spontaneous subarachnoid hemorrhage in Martinique is much lower than in other parts of the world and similar to countries in Central and South America. These results are possibly related to environmental factors and most particularly to a low rate of smoking in the Martinican population. Thirty-day case-fatality rate is similar to what is observed in developed countries.

    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

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

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

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

    A 67-year-old Korean woman attended our hospital complaining of a severe headache. A brain computed tomography scan showed conglomerated, high-density, calcified nodules in the left temporo-occipito-parietal area and high-density subarachnoid hemorrhage in the basal cisterns. Magnetic resonance imaging of the brain shows multiple conglomerated iso- or low-signal intensity round nodules with peripheral rim enhancement. She underwent craniotomies to clip the aneurysm and remove the calcified masses. Paragonimus westermani eggs were identified in the calcified necrotic lesions. Results of parasitic examinations on the sputum and an enzyme-linked immunosorbent assay for P. westermani were all negative. The patient presented with headache and dizziness that had occurred for more than 30 years. She had not eaten freshwater crayfish or crabs. However, she had sometimes prepared raw crabs for several decades. Overall, this case was diagnosed as chronic cerebral paragonimiasis, in which she may have been infected through the contamination of utensils during the preparation of the second intermediate hosts, combined with a cerebral hemorrhage.

    Subarachnoid hemorrhage (SAH) due to the rupture of an intracranial aneurysm (IA) is a rare but serious complication of pregnancy and is responsible for important morbidity and mortality during pregnancy. This study reviewed reports of ruptured IA during pregnancy and the puerperium, and our own cases of ruptured IA in pregnant women. Hemorrhage occurred predominantly during the third trimester of pregnancy, when maternal cardiac output and blood volume increase and reach maximum. Physiological and hormonal changes in pregnancy are likely to affect the risk of IA rupture. Ruptured IAs during pregnancy should be managed based on neurosurgical considerations, and the obstetrical management of women with ruptured IAs should be decided according to the severity of SAH and the gestational age. Emergent cesarean section followed by clipping or coiling of aneurysms is indicated if the maternal condition and the gestational age allow such interventions. Although SAH during pregnancy can result in disastrous outcomes, the necessity of intracranial screening for high-risk pregnant women is still controversial. PMID:23979051

    Subarachnoid hemorrhage (SAH) is rare in young adults and little is known about aneurysms in this subgroup. The effect of clinical and prognostic factors on the outcome based on the Glasgow Outcome Scale (GOS) scores and the predictors of unfavorable outcomes were analyzed in young adults with aneurysmal SAH. A retrospective review of the clinical parameters, including age, sex, hypertension, smoking status, hyperlipidemia, location of the cerebral aneurysm, size of the aneurysm, multiplicity, perioperative complication such as hydrocephalus, vasospasm, and hematoma, and Hunt and Hess and Fisher grading on presentation, was conducted in 108 young adults (mean age 34.8 years) managed at our institute. The outcome was classified based on GOS grading into unfavorable (GOS scores 1-3) or favorable (GOS scores 4 or 5). The overall mortality rate was 3.7% (4/108 patients). Univariate regression analysis for the outcomes at discharge found that age at the time of presentation, male sex, size of aneurysm, multiple aneurysms, hyperlipidemia, and poor Hunt and Hess and Fischer grades were associated with unfavorable outcome. Multivariate regression analysis found independent effects of sex, multiple aneurysms, size of aneurysm, and Hunt and Hess grade on the outcome at discharge. Size of aneurysm, presence of multiple aneurysms, Hunt and Hess grade, and hypertension were the predictors of outcome at mean 2-year follow up based on multivariate exact regression analysis. The multimodal approach with aggressive medical management, early intervention, and surgical treatment might contribute to favorable long-term outcomes in patients with poor expected outcomes.

  16. Subarachnoid Hemorrhage, Spreading Depolarizations and Impaired Neurovascular Coupling

    Full Text Available Aneurysmal subarachnoid hemorrhage (SAH has devastating consequences on brain function including profound effects on communication between neurons and the vasculature leading to cerebral ischemia. Physiologically, neurovascular coupling represents a focal increase in cerebral blood flow to meet increased metabolic demand of neurons within active regions of the brain. Neurovascular coupling is an ongoing process involving coordinated activity of the neurovascular unit—neurons, astrocytes, and parenchymal arterioles. Neuronal activity can also influence cerebral blood flow on a larger scale. Spreading depolarizations (SD are self-propagating waves of neuronal depolarization and are observed during migraine, traumatic brain injury, and stroke. Typically, SD is associated with increased cerebral blood flow. Emerging evidence indicates that SAH causes inversion of neurovascular communication on both the local and global level. In contrast to other events causing SD, SAH-induced SD decreases rather than increases cerebral blood flow. Further, at the level of the neurovascular unit, SAH causes an inversion of neurovascular coupling from vasodilation to vasoconstriction. Global ischemia can also adversely affect the neurovascular response. Here, we summarize current knowledge regarding the impact of SAH and global ischemia on neurovascular communication. A mechanistic understanding of these events should provide novel strategies to treat these neurovascular disorders.

    Full Text Available Background. Although relaxin causes vasodilatation in systemic arteries, little is known about its role in cerebral arteries. We investigated the expression and role of relaxin in basilar arteries after subarachnoid hemorrhage (SAH in rabbits. Methods. Microarray analysis with rabbit basilar artery RNA was performed. Messenger RNA expression of relaxin-1 and relaxin/insulin-like family peptide receptor 1 (RXFP1 was investigated with quantitative RT-PCR. RXFP1 expression in the basilar artery was investigated with immunohistochemistry. Relaxin concentrations in cerebrospinal fluid (CSF and serum were investigated with an enzyme-linked immunosorbent assay. Using human brain vascular smooth muscle cells (HBVSMC preincubated with relaxin, myosin light chain phosphorylation (MLC was investigated with immunoblotting after endothelin-1 stimulation. Results. After SAH, RXFP1 mRNA and protein were significantly downregulated on day 3, whereas relaxin-1 mRNA was significantly upregulated on day 7. The relaxin concentration in CSF was significantly elevated on days 5 and 7. Pretreatment with relaxin reduced sustained MLC phosphorylation induced by endothelin-1 in HBVSMC. Conclusion. Upregulation of relaxin and downregulation of RXFP1 after SAH may participate in development of cerebral vasospasm. Downregulation of RXFP1 may induce a functional decrease in relaxin activity during vasospasm. Understanding the role of relaxin may provide further insight into the mechanisms of cerebral vasospasm.

    Full Text Available Background. Aneurysmal subarachnoid hemorrhage (aSAH survivors commonly exhibit impairment on phonemic and semantic fluency tests; however, it is unclear which of the contributing cognitive processes are compromised in aSAH patients. One method of disentangling these processes is to compare initial word production, which is a rapid, semiautomatic, frontal-executive process, and late phase word production, which is dependent on more effortful retrieval and lexical size and requires a more distributed neural network. Methods. Seventy-two individuals with aSAH and twenty-five control subjects were tested on a cognitive battery including the phonemic and semantic fluency task. Demographic and clinical information was also collected. Results. Compared to control subjects, patients with aSAH were treated by clipping and those with multiple aneurysms were impaired across the duration of the phonemic test. Among patients treated by coiling, those with anterior communicating artery aneurysms or a neurological complication (intraventricular hemorrhage, vasospasm, and edema showed worse output only in the last 45 seconds of the phonemic test. Patients performed comparably to control subjects on the semantic test. Conclusions. These results support a “diffuse damage” hypothesis of aSAH, indicated by late phase phonemic fluency impairment. Overall, the phonemic and semantic tests represent a viable, rapid clinical screening tool in the postoperative assessment of patients with aSAH.

    Intracranial pressure (ICP) should ideally be measured in many conditions affecting the brain. The invasiveness and associated risks of the measurement modalities in current clinical practice restrict ICP monitoring to a small subset of patients whose diagnosis and treatment could benefit from ICP measurement. To expand validation of a previously proposed model-based approach to continuous, noninvasive, calibration-free, and patient-specific estimation of ICP to patients with subarachnoid hemorrhage (SAH), we made waveform recordings of cerebral blood flow velocity in several major cerebral arteries during routine, clinically indicated transcranial Doppler examinations for vasospasm, along with time-locked waveform recordings of radial artery blood pressure (APB), and ICP was measured via an intraventricular drain catheter. We also recorded the locations to which ICP and ABP were calibrated, to account for a possible hydrostatic pressure difference between measured ABP and the ABP value at a major cerebral vessel. We analyzed 21 data records from five patients and were able to identify 28 data windows from the middle cerebral artery that were of sufficient data quality for the ICP estimation approach. Across these windows, we obtained a mean estimation error of -0.7 mmHg and a standard deviation of the error of 4.0 mmHg. Our estimates show a low bias and reduced variability compared with those we have reported before. PMID:27165879

    Aim: To investigate the clinical and radiological features of meningitis with subarachnoid diffusion-weighted imaging (DWI) hyperintensity. Materials and methods: The clinical features, laboratory data, and radiological findings, including the number and distribution of subarachnoid DWI hyperintense lesions and other radiological abnormalities, of 18 patients seen at five institutions were evaluated. Results: The patients consisted of eight males and 10 females, whose ages ranged from 4 months to 82 years (median 65 years). Causative organisms were bacteria in 15 patients, including Haemophilus influenzae, Streptococcus pneumoniae, Streptococcus agalactiae, Staphylococcus aureus, Klebsiella pneumoniae, and Listeria monocytogenes. The remaining three were fungal meningitis caused by Cryptococcus neoformans. Subarachnoid DWI hyperintense lesions were multiple in 16 of the 18 cases (89%) and predominantly distributed around the frontal lobe in 16 of the 18 cases (89%). In addition to subarachnoid abnormality, subdural empyema, cerebral infarction, and intraventricular empyema were found in 50, 39, and 39%, respectively. Compared with paediatric patients, adult patients with bacterial meningitis tended to have poor prognoses (7/10 versus 1/5; p = 0.1). Conclusion: Both bacterial and fungal meningitis could cause subarachnoid hyperintensity on DWI, predominantly around the frontal lobe. This finding is often associated with poor prognosis in adult bacterial meningitis.

    Haemorrhagic septicaemia (HS) is an acute fatal infectious disease of mainly cattle and buffalo and outbreaks occur commonly in Cambodia. Disease outbreak reports were examined to select five villages from three provinces for a retrospective investigation of HS epidemiology and socioeconomic impact on smallholders, with an aim of identifying potential benefits from improving disease prevention through biosecurity and vaccination. The Village Animal Health Worker (VAHW) or Chief in each village and 66 affected smallholders were surveyed. At the village level, 24% of all households were affected with an estimated mean village herd morbidity of 10.1% and mortality of 28.8%. Affected farmers reported HS disease morbidity and mortality at 42.7% and 63.6% respectively. Buffalo had a higher morbidity (OR = 2.3; P = 0.003) and mortality (OR = 6.9; P smallholders and remains a critical constraint to improving large ruminant productivity and profitability. Addressing HS disease control requires a focus on improving smallholder farmer knowledge of biosecurity and vaccination and should be priority to stakeholders interested in addressing regional food insecurity and poverty reduction.

    Full Text Available Brain contains large amounts of tissue factor, the major initiator of the coagulation cascade. Neuronal apoptosis after intracerebral haemorrhage (ICH leads to the shedding of procoagulant phospholipids (PPLs. The aim of this study was to investigate the generation of PPL, tissue factor activity (TFa, and D-Dimer (D-Di in the cerebrospinal fluid (CSF at the acute phase of ICH in comparison with other brain diseases and to examine the relationship between these factors and the outcome of ICH. CSF was collected from 112 patients within 48 hours of hospital admission. Thirty-one patients with no neurological or biochemical abnormalities were used to establish reference range in the CSF (“controls”. Thirty had suffered an ICH, and 51 other neurological diagnoses [12: ventricular drainage following brain surgery, 13: viral meningitis, 15: bacterial meningitis, and 11 a neurodegenerative disease (NDD]. PPL was measured using a factor Xa-based coagulation assay and TFa by one home test. PPL, D-Di, and TFa were significantly higher (P<0.001 in the CSF of patients with ICH than in controls. TFa levels were significantly (P<0.05 higher in ICH than in patients with meningitides or NDD. Higher levels (P<0.05 of TFa were observed in patients with ICH who died than in survivors. TFa measurement in the CSF of patients with ICH could constitute a new prognostic marker.

    Full Text Available Introduction: Intracranial haemorrhage (ICH is associated with high mortality and morbidity, and for this reason it is the most feared complication of oral anticoagulant therapy (OAT. Recommendations are available for the immediate reversal of OAT, but these measures are not always used uniformly and rapidly. The aim of this study was to critically review the treatment of spontaneous OAT-related ICH in our hospital. Materials and methods: We retrospectively analyzed the medical records of patients admitted to our ward between January 2006 and January 2010 for spontaneous OAT-related ICH. Results: In the analyzed period, 15 patients were hospitalized for OAT-related ICH (supratentorial in 66.5%, infratentorial in 20%, acute subdural hematoma in 13.5%. In 66.5% of the patients, the INR on arrival was within the therapeutic range. In 60% of the cases, the Glasgow Coma Scale (GCS on arrival was > 8/15. Three-factor prothrombin complex concentrate (PCC was administered in 80% of the cases, and 30% of patients received fresh frozen plasma (FFP and recombinant activated factor VII (FVIIra. One patient received PCC plus PFC, and another received PCC with FVIIra. FFP alone was used in 13.5% of the patients. All of the patients received intravenously administered vitamin K1. Treatment was started in the Emergency Room in 33.5% of the cases; in the other 66.5% it began on our ward. In 66.5% of the patients, the treatment was effective in reversing OATwithin 8 hours. In 2 cases, the hematoma was surgically evacuated, and the patients survived. Total mortality for OAT-related ICH was 46.5% (32.9% in non-OAT-related ICH. In 71.5% of the patients with OAT-related haemorrhages, death occurred within 48 hours of arrival. Sixty percent of the patients with ICH > 60 cm3 (20% in patients with ICH < 60 cm3 and 100% of those with GCS < 7/15 died. For survivors, the median modified Rankin Scale at discharge was 3. All survivors were still alive at 3 months after

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

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

    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.

    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

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

    International Nuclear Information System (INIS)

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

    Full Text Available Background : Hyponatremia is the most common electrolyte abnormality seen in patients with aneurysmal SAH. Clinically significant hyponatremia (Serum Sodium <131 mEq/L which needs treatment, has been redefined recently and there is a paucity of outcome studies based on this. This study aims to identify the mean Serum Sodium (S.Na+ level and its duration among inpatients with SAH and to identify the relationship between hyponatremia and the outcome status of patients undergoing surgery for SAH. Materials and Methods : This outcome study is undertaken in the department of neurosurgery, The Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala. Medical records of all patients with SAH from 1 st January to 31 st July 2010 were reviewed. Preoperative status was assessed using World Federation of Neurosurgical Societies (WFNS grading system. Discharge status was calculated using the Glasgow outcome score scale. Results : Fifty nine patients were included in the study and 53 (89.8% of them have undergone surgical treatment. Hyponatremia was observed in 22 of 59 patients (37%. The mean Sodium level of hyponatremic patients was 126.97 mEq/L for a median duration of two days. Glasgow outcome score was good in 89.8% of patients. We lost two patients, one of whom had hyponatremia and vasospasm. Conclusion : Hyponatremia is significantly associated with poor outcome in patients with SAH. Anticipate hyponatremia in patients with aneurysmal subarachnoid hemorrhage, timely detect and appropriately treat it to improve outcome. It is more common in patients who are more than 50 years old and whose aneurysm is in the anterior communicating artery. Our comprehensive monitoring ensured early detection and efficient surgical and nursing management reduced morbidity and mortality.

    2014-07-01

    Full Text Available BACKGROUND: Following spinal anesthesia it is very important to see complete recovery before ambulation and discharge of the patient. Conventional methods to see recovery from spinal block use different types of motor power tests like Bromage score or the Formal motor power test system. MATERIAL AND METHODS: A total of one hundred and fifty patients of ASA grade I and II, presenting for lower segment caesarean section under spinal anesthesia were taken up for the study. We compared the use of a 128-Hz tuning fork with the results of conventional evaluation of block recovery. Conventional block recovery testing included Bromage score, Formal muscle power testing according to the British Medical Research Council, pinprick testing, and warm/cold testing. After obtaining base line values, a subarachnoid block was performed and patients were tested every 15 minutes after surgery, till the vibration score of one less than the baseline was achieved. Statistical analysis was performed to compare the results of the different methods to the time at which baseline values of vibration sense were reached. RESULTS: At the time vibration sense testing returned to baseline, 100% of the patients had attained Bromage score of 0 with no residual motor block. 98% of the patients regained foot extension and foot flexion strength completely while 92% of the patients showed complete recovery of the quadriceps strength. CONCLUSION: Recovery of vibration sense corresponds with recovery of motor block after spinal anesthesia and may serve as an easy means of documenting recovery with a single test before discharge.

    Sub-arachnoid hemorrhage (SAH) has been easily one of the most debilitating neurosurgical entities as far as stroke related case mortality and morbidity rates are concerned. To date, it has case fatality rates ranging from 32-67%. Advances in the diagnostic accuracy of the available imaging methods have contributed significantly in reducing morbidity associated with this deadly disease. We currently have computed tomography angiography (CTA), magnetic resonance angiography (MRA) and the digital subtraction angiography (DSA) including three dimensional DSA as the mainstay diagnostic techniques. The non-invasive angiography in the form of CTA and MRA has evolved in the last decade as rapid, easily available, and economical means of diagnosing the cause of SAH. The role of three dimensional computed tomography angiography (3D-CTA) in management of aneurysms has been fairly acknowledged in the past. There have been numerous articles in the literature regarding its potential threat to the conventional "gold standard" DSA. The most recent addition has been the introduction of the fourth dimension to the established 3D-CT angiography (4D-CTA). At many centers, DSA is still treated as the first choice of investigation. Although, CT angiography still has some limitations, it can provide an unmatched multi-directional view of the aneurysmal morphology and its surroundings including relations with the skull base and blood vessels. We study the recent advances in the diagnostic approaches to SAH with special emphasis on 3D-CTA and 4D-CTA as the upcoming technologies. PMID:22347331

  12. The Early Endocrine Stress Response in Experimental Subarachnoid Hemorrhage.

    Directory of Open Access Journals (Sweden)

    Christoffer Nyberg

    Full Text Available In patients with severe illness, such as aneurysmal subarachnoid hemorrhage (SAH, a physiologic stress response is triggered. This includes activation of the hypothalamic-pituitary-adrenal (HPA axis and the sympathetic nervous system. The aim of this study was to investigate the very early responses of these systems.A porcine animal model of aneurysmal SAH was used. In this model, blood is injected slowly to the basal cisterns above the anterior skull base until the cerebral perfusion pressure is 0 mm Hg. Sampling was done from blood and urine at -10, +15, +75 and +135 minutes from time of induction of SAH. Analyses of adrenocorticotropic hormone (ACTH, cortisol, aldosterone, catecholamines and chromogranin-A were performed.Plasma ACTH, serum cortisol and plasma aldosterone increased in the samples following induction of SAH, and started to decline after 75 minutes. Urine cortisol also increased after SAH. Urine catecholamines and their metabolites were found to increase after SAH. Many samples were however below detection level, not allowing for statistical analysis. Plasma chromogranin-A peaked at 15 minutes after SAH, and thereafter decreased.The endocrine stress response after aneurysmal SAH was found to start within 15 minutes in the HPA axis with early peak values of ACTH, cortisol and aldosterone. The fact that the concentrations of the HPA axis hormones decreased 135 minutes after SAH may suggest that a similar pattern exists in SAH patients, thus making it difficult to catch these early peak values. There were also indications of early activation of the sympathetic nervous system, but the small number of valid samples made interpretation difficult.

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

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

  17. Risk of stroke after acute myocardial infarction among Chinese

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Following an acute myocardial infarction (AMI), patients have an increased risk of stroke. Estimates of risk are mainly derived from AMI treatment trials or secondary prevention studies. The reported incidence of stroke in Caucasians in the early phase after AMI ranged from 0.5% to 2.5%.1-3 Similar assessment of risk in the Chinese population is lacking. As thrombolytic therapy becomes standard treatment for AMI, there is concern that there may be an increase in haemorrhagic stroke complicating AMI treatment, especially since haemorrhagic stroke is more common in Asian populations.

    Full Text Available Abstract Background Severe brain edema is observed in a number of patients suffering from subarachnoid hemorrhage (SAH. Little is known about its pathogenesis and time-course in the first hours after SAH. This study was performed to investigate the development of brain edema and its correlation with brain perfusion after experimental SAH. Methods Male Sprague–Dawley rats, randomly assigned to one of six groups (n = 8, were subjected to SAH using the endovascular filament model or underwent a sham operation. Animals were sacrificed 15, 30, 60, 180 or 360 minutes after SAH. Intracranial pressure (ICP, mean arterial blood pressure (MABP, cerebral perfusion pressure (CPP and bilateral local cerebral blood flow (LCBF were continuously measured. Brain water content (BWC was determined by the wet/dry-weight method. Results After SAH, CPP and LCBF rapidly decreased. The decline of LCBF markedly exceeded the decline of CPP and persisted until the end of the observation period. BWC continuously increased. A significant correlation was observed between the BWC and the extent of the perfusion deficit in animals sacrificed after 180 and 360 minutes. Conclusions The significant correlation with the perfusion deficit after SAH suggests that the development of brain edema is related to the extent of ischemia and acute vasoconstriction in the first hours after SAH.

    Full Text Available Dengue is an acute mosquito-borne infection caused by dengue viruses from the genus flavivirus. Neurologic complications have been attributed chiefly to metabolic alterations and to focal and sometimes massive intracranial haemorrhages, but anecdotal cases and limited case series have indicated the possibility of viral CNS and skeletal muscle invasion causing encephalitis and myositis. We present a case of a 40-year-old male who presented with severe dengue myositis resulting in quadriparesis, respiratory failure and acute renal failure with red urine. His elevated serum creatine kinase (CK, serum and urine myoglobin levels justified rhabdomyolysis as the cause of acute renal failure. A muscle biopsy revealed inflammatory myositis. He required ventilator support for respiratory failure and was treated conservatively. This case highlights the severe and persistent muscle involvement in dengue which is a rarity.

    Full Text Available BACKGROUND AND OBJECTIVES: The prophylactic effect of ondansetron on subarachnoid morphine-induced pruritus is controversial, while evidence suggests that droperidol prevents pruritus. The aim of this study is to compare the effects of droperidol and ondansetron on subarachnoid morphine-induced pruritus.METHODS: 180 ASA I or II patients scheduled to undergo cesarean sections under subarachnoid anesthesia combined with morphine 0.2 mg were randomized to receive, after the child's birth, metoclopramide 10 mg (Group I - control, droperidol 2.5 mg (Group II or ondansetron 8 mg (Group III. Postoperatively, the patients were assessed for pruritus (absent, mild, moderate or severe or other side effects by blinded investigators. Patients were also blinded to their group allocation. The tendency to present more severe forms of pruritus was compared between groups. NNT was also determined.RESULTS: Patients assigned to receive droperidol [Proportional odds ratio: 0.45 (95% confidence interval 0.23-0.88] reported less pruritus than those who received metoclopramide. Ondansetron effect was similar to metoclopramide [Proportional odds ratio: 0.95 (95% confidence interval 0.49-1.83]. The NNT for droperidol and ondansetron was 4.0 and 14.7, respectively.CONCLUSIONS: Ondansetron does not inhibit subarachnoid morphine-induced pruritus.

    Objectives To reveal the relationship of brain motion and cerebrospinal fluid (CSF) flow by phase-contrast cine MRI, and to evaluate this technique in differentiating between arachnoid cysts and subarachnoid space enlargement. Methods Using a phase-contrast cine MRI pulse sequence, we measured brain motion and CSF flow during the cardiac cycle in 10 healthy volunteers and 10 patients with MRI-suspected arachnoid cyst or subarachnoid space enlargement. CSF stroke volume curve was illustrated according to flow quantification, and time-signal intensity curve was traced. The two curves were compared. Results This study showed that brain motion was due to the volume difference between arterial and venous blood flow during a cardiac cycle, and thus drives CSF pulsation. Arachnoid cysts and subarachnoid space enlargement carried different curve patterns, demonstrating that phase-contrast MRI and flow quantification can be a useful and reliable technique for non-invasive evaluation of brain motion and CSF flow. Conclusion Arachnoid cysts can be successfully differentiated using phase-contrast cine MRI from subarachnoid space enlargement.

    Full Text Available BACKGROUND: Matrix metalloproteinases (MMPs and their tissue inhibitors (TIMPs are involved in vascular remodeling, (neuroinflammation, blood-brain barrier breakdown and neuronal apoptosis. Proinflammatory mechanisms are suggested to play an important role during early brain injury and cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH. This study aimed to analyze MMP-3, MMP-9, TIMP-1 and TIMP-3 in patients with SAH and their respective association with cerebral vasospasm (CVS. METHODS: Blood samples were collected in 20 SAH patients on days 1 to 7, 9, 11, 13 and 15 and 20 healthy age and gender matched volunteers. Serum MMPs and TIMPs were analyzed using enzyme-linked immunosorbent assay. Doppler sonographic CVS was defined as a mean blood flow velocity above 120 cm/sec in the middle cerebral artery. When discharged from hospital and at 6 month follow-up neurological outcome was evaluated using the Glasgow Outcome Score and the modified Rankin Scale. RESULTS: MMP-9 was higher in SAH patients compared to healthy controls (p<0.001. Patients with CVS (n = 11 had elevated MMP-9 serum levels compared to patients without CVS (n = 9, p<0.05. Higher MMP-9 was observed in the presence of cerebral ischemia associated with cerebral vasospasm (p<0.05. TIMP-1 was increased in patients with SAH on day 4 (p<0.05. There was an imbalance of the MMP-9/TIMP-1 ratio in favor of MMP-9 in SAH patients, in particular those with CVS (p<0.001. MMP-3 and TIMP-3 were significantly lower in SAH patients throughout day 4 and day 7, respectively (p<0.05. We did not find an association between MMP-, TIMP levels and neurological outcome after 6 months. CONCLUSIONS: MMP-3 and -9 are differentially regulated in SAH patients with both enzymes showing peak levels correlating with the development of CVS. The inhibitors TIMP-1 and -3 were low during the acute phase after SAH and increased later on which might suggest a preponderance of pro-inflammatory mechanisms.

    The diagnosis of acute pancreatitis is based on anamnestic, clinical and chemical data. Ultrasound and computed tomography permit direct visualisation of the pancreas and establish the diagnosis. In cases of haemorrhagic-necrotising pancreatitis they demonstrate the extent of morphological changes and permit exclusion of other causes of an acute abdomen. The imaging methods support indications for operation in cases of subtotal or total parenchymatous necrosis and in pancreatic abscesses. Conservative expectant approaches in patients with severe clinical course and slight morphological changes as well as in agreement of clinical and morphological findings are facilitated. Complete demonstration of parenchymatous and peripancreatic necroses furnishes useful additional information for total extirpation. Gallstone disease can be demonstrated or excluded preoperatively. Since introduction of ultrasound and computed tomography for the diagnosis of acute pancreatitis a marked diminution of early surgical intervention and delayed operation has been achieved.

  6. In vitro study of cerebrospinal fluid dynamics in a shaken basal cistern after experimental subarachnoid hemorrhage.

    Directory of Open Access Journals (Sweden)

    Ulrich Kertzscher

    Full Text Available BACKGROUND: Cerebral arterial vasospasm leads to delayed cerebral ischemia and constitutes the major delayed complication following aneurysmal subarachnoid hemorrhage. Cerebral vasospasm can be reduced by increased blood clearance from the subarachnoid space. Clinical pilot studies allow the hypothesis that the clearance of subarachnoid blood is facilitated by means of head shaking. A major obstacle for meaningful clinical studies is the lack of data on appropriate parameters of head shaking. Our in vitro study aims to provide these essential parameters. METHODOLOGY/PRINCIPAL FINDINGS: A model of the basal cerebral cistern was derived from human magnetic resonance imaging data. Subarachnoid hemorrhage was simulated by addition of dyed experimental blood to transparent experimental cerebrospinal fluid (CSF filling the model of the basal cerebral cistern. Effects of various head positions and head motion settings (shaking angle amplitudes and shaking frequencies on blood clearance were investigated using the quantitative dye washout method. Blood washout can be divided into two phases: Blood/CSF mixing and clearance. The major effect of shaking consists in better mixing of blood and CSF thereby increasing clearance rate. Without shaking, blood/CSF mixing and blood clearance in the basal cerebral cistern are hampered by differences in density and viscosity of blood and CSF. Blood clearance increases with decreased shaking frequency and with increased shaking angle amplitude. Head shaking facilitates clearance by varying the direction of gravitational force. CONCLUSIONS/SIGNIFICANCE: From this in vitro study can be inferred that patient or head shaking with large shaking angles at low frequency is a promising therapeutic strategy to increase blood clearance from the subarachnoid space.

    On examination in our clinic, he showed alert consciousness, with nuchal rigidity and left weakness. A lumbar puncture showed an opening pressure of 125 mm H/sub 2/O, xanthochromic in nature, and the cerebrospinal fluid contained 40 white cells per cubic millimeter, mostly lymphocytes, though the total protein and glucose contents were normal. Blood, general, and chemical examinations showed a normal white-cell count and increasing titers of GPT (420), GOT (203), and LDH (723). A computed-tomographic scan of the brain on the day of admission revealed bilateral frontal and right temporal abnormal low-density areas, greater on the right side, and contrast enhancement in the bilateral frontal and right paraventricular regions. Cerebral angiography demonstrated a marked hypervascularity in the bilateral frontal regions in the arterial phase. A diagnosis of herpes simplex encephalitis was made on the basis of the clinical course and the angiographic and computed-tomographicscan findings. On the day of admission, the patient vomited once. On the third hospital day, he complained of a headache and became somnolent. After that, a mild fever continued for two weeks. On the eleventh hospital day, he occasionally vomited after a headache. On the fifteenth hospital day, a repeat spinal tap was performed with an opening pressure of 150 mm H/sub 2/O. The total white blood cell count was 25/cu mm. On the twenty-fourth hospital day, the headache and vomiting disappeared, and the fever also subsided. He was discharged about two months later with minimal mental abnormality.

    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.

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

    International Nuclear Information System (INIS)

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

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

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

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

  13. Frequency of causes of primary postpartum haemorrhage in a tertiary care hospital

    International Nuclear Information System (INIS)

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

    it is difficult to diagnose because of its nonspecific presentation. This condition frequently occurs in association with an extreme physical stress and may lead to acute adrenal insufficiency or death if not promptly and properly treated. We report a rare case of acute bilateral adrenal hemorrhage with adrenal insufficiency following duodenopancreatectomy for ampulloma in absence of surgical complications. Early diagnosis and corticosteroid replacement with aggressive management of the precipitating pathology are essential to enable a successful outcome. PMID:25945442

    Delayed ischemic neurologic deficit after subarachnoid hemorrhage results from loss of neural cells. Nerve growth factor and its receptor TrkA may promote regeneration of neural cells, but their expression after subarachnoid hemorrhage remains unclear. In the present study, a rat model of subarachnoid hemorrhage was established using two injections of autologous blood into the cistern magna. Immunohisto-chemical staining suggested that the expression of nerve growth factor and TrkA in the cerebral cortex and brainstem increased at 6 hours, peaked at 12 hours and decreased 1 day after induction of subarachnoid hemorrhage, whereas the expression in the hippocampus increased at 6 hours, peaked on day 1, and decreased 3 days later. Compared with those for the rats in the sham and saline groups, neurobehavioral scores decreased significantly 12 hours and 3 days after subarachnoid hemorrhage (P < 0.05). These results suggest that the expression of nerve growth factor and its receptor TrkA is dynamically changed in the rat brain and may thus participate in neuronal survival and nerve regeneration after subarachnoid hemorrhage.

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

    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.

    Conclusions and implications: The failure of incorporation Gal excludes the possibility of the hepatic NAcNeu Gal transferase capping the oligosaccharides with sialic acid. This has two desirable haemostatic outcomes: fibrin monomers will polymerise and form clots more rapidly, and two galactose residues can never be exposed diminishing uptake of the protein by the asialoglycoprotein receptor and ramping up concentration at a time of challenge.

  19. The clinical importance of expanded subarachnoid spaces detected by CT in early infancy

    International Nuclear Information System (INIS)

    It depends on the clinical course and on follow-jup CT findings whether expansions of the subarachnoid space should be considered as pathological changes or as normal. There is no direct correlation between the degree of severity of the clinical symptoms on the one hand and the CT changes on the other. The clinical course and the follow-up CT images are found to be uncorrelated, too. CT findings alone are insufficient in predicting children's development. Especially in the case of unspecific changes, e.g. slight expansions of the subarachnoid space, cranial CT can only provide further proof of a suspected clinical diagnosis. The ventricular indices frequently used for CT interpretation can rarely be used as decision aids or as factors providing new information. (orig./MG)

    To analyse diffusion-weighted MRI of acute spinal cord trauma and evaluate its diagnostic value. Conventional MRI and multishot, navigator-corrected DWI were performed in 20 patients with acute spinal cord trauma using 1.5-T MR within 72 h after the onset of trauma. Twenty cases were classified into four categories according to the characteristics of DWI: (1) Oedema type: ten cases presented with variable hyperintense areas within the spinal cord. There were significant differences in the apparent diffusion coefficients (ADCs) between lesions and unaffected regions (t = -7.621, P < 0.01). ADC values of lesions were markedly lower than those of normal areas. (2) Mixed type: six cases showed heterogeneously hyperintense areas due to a mixture of haemorrhage and oedema. (3) Haemorrhage type: two cases showed lesions as marked hypointensity due to intramedullary haemorrhage. (4) Compressed type (by epidural haemorrhage): one of the two cases showed an area of mild hyperintensity in the markedly compressed cord due to epidural haematoma. Muti-shot DWI of the spinal cord can help visualise and evaluate the injured spinal cord in the early stage, especially in distinguishing the cytotoxic oedema from vasogenic oedema. It can assist in detecting intramedullary haemorrhage and may have a potential role in the evaluation of compressed spinal cord. (orig.)

    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.)

    Full Text Available Introduction. Stroke is a leading cause of mortality and morbidity in the United States. About 20% of the stroke is hemorrhagic and about 50% of these is due to aneurysmal subarachnoid hemorrhage. A troublesome neuropsychiatric complication of subarachnoid hemorrhage is agitation/aggression. Case Presentation. A 45-year-old man with no prior psychiatric history, sustained subarachnoid hemorrhage. After initial stabilization for 2 days, he underwent craniotomy and clipping of anterior cerebral communicating artery aneurysm. Treatment was continued with labetalol, nimodipine, and levetiracetam. Beginning postoperative day 4, patient developed episodes of confusion and agitation/aggression. Switching of Levetiracetam to valproate did not show any improvement. Psychiatry team tried to manage him with intense nursing intervention and different medications like olanzapine, valproate, lorazepam, and haloperidol. However, patient continued to be agitated and aggressive. Switching from labetalol to metoprolol resulted in dramatic improvement within 3 days. Discussion. Antipsychotics and benzodiazepines are often not sufficiently effective in the control of agitation/aggression in patients with traumatic brain injury and similar conditions. Our case report and the literature review including a cochrane review suggests that beta-blockers may be helpful in this situation.

  12. Methemoglobin Is an Endogenous Toll-Like Receptor 4 Ligand—Relevance to Subarachnoid Hemorrhage

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Neuroinflammation is a well-recognized consequence of subarachnoid hemorrhage (SAH, and may be responsible for important complications of SAH. Signaling by Toll-like receptor 4 (TLR4-mediated nuclear factor κB (NFκB in microglia plays a critical role in neuronal damage after SAH. Three molecules derived from erythrocyte breakdown have been postulated to be endogenous TLR4 ligands: methemoglobin (metHgb, heme and hemin. However, poor water solubility of heme and hemin, and lipopolysaccharide (LPS contamination have confounded our understanding of these molecules as endogenous TLR4 ligands. We used a 5-step process to obtain highly purified LPS-free metHgb, as confirmed by Fourier Transform Ion Cyclotron Resonance mass spectrometry and by the Limulus amebocyte lysate assay. Using this preparation, we show that metHgb is a TLR4 ligand at physiologically relevant concentrations. metHgb caused time- and dose-dependent secretion of the proinflammatory cytokine, tumor necrosis factor α (TNFα, from microglial and macrophage cell lines, with secretion inhibited by siRNA directed against TLR4, by the TLR4-specific inhibitors, Rs-LPS and TAK-242, and by anti-CD14 antibodies. Injection of purified LPS-free metHgb into the rat subarachnoid space induced microglial activation and TNFα upregulation. Together, our findings support the hypothesis that, following SAH, metHgb in the subarachnoid space can promote widespread TLR4-mediated neuroinflammation.

    Full Text Available Objective. The novel clinical prediction approach of Bayesian neural networks with fuzzy logic inferences is created and applied to derive prognostic decision rules in cerebral aneurysmal subarachnoid hemorrhage (aSAH. Methods. The approach of Bayesian neural networks with fuzzy logic inferences was applied to data from five trials of Tirilazad for aneurysmal subarachnoid hemorrhage (3551 patients. Results. Bayesian meta-analyses of observational studies on aSAH prognostic factors gave generalizable posterior distributions of population mean log odd ratios (ORs. Similar trends were noted in Bayesian and linear regression ORs. Significant outcome predictors include normal motor response, cerebral infarction, history of myocardial infarction, cerebral edema, history of diabetes mellitus, fever on day 8, prior subarachnoid hemorrhage, admission angiographic vasospasm, neurological grade, intraventricular hemorrhage, ruptured aneurysm size, history of hypertension, vasospasm day, age and mean arterial pressure. Heteroscedasticity was present in the nontransformed dataset. Artificial neural networks found nonlinear relationships with 11 hidden variables in 1 layer, using the multilayer perceptron model. Fuzzy logic decision rules (centroid defuzzification technique denoted cut-off points for poor prognosis at greater than 2.5 clusters. Discussion. This aSAH prognostic system makes use of existing knowledge, recognizes unknown areas, incorporates one's clinical reasoning, and compensates for uncertainty in prognostication.

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

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

    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.

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

    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)

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

    International Nuclear Information System (INIS)

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

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

    Full Text Available The ability of Taenia solium to modulate the immune system likely contributes to their longevity in the human host. We tested the hypothesis that the nature of the immune response is related to the location of parasite and clinical manifestations of infection.Peripheral blood mononuclear cells (PBMC were obtained from untreated patients with neurocysticercosis (NCC, categorized as having parenchymal or subarachnoid infection by the presence of cysts exclusively within the parenchyma or in subarachnoid spaces of the brain, and from uninfected (control individuals matched by age and gender to each patient. Using multiplex detection technology, sera from NCC patients and controls and cytokine production by PBMC after T. solium antigen (TsAg stimulation were assayed for levels of inflammatory and regulatory cytokines. PBMC were phenotyped by flow cytometry ex vivo and following in vitro stimulation with TsAg.Sera from patients with parenchymal NCC demonstrated significantly higher Th1 (IFN-γ/IL-12 and Th2 (IL-4/IL-13 cytokine responses and trends towards higher levels of IL-1β/IL-8/IL-5 than those obtained from patients with subarachnoid NCC. Also higher in vitro antigen-driven TNF-β secretion was detected in PBMC supernatants from parenchymal than in subarachnoid NCC. In contrast, there was a significantly higher IL-10 response to TsAg stimulation in patients with subarachnoid NCC compared to parenchymal NCC. Although no differences in regulatory T cells (Tregs frequencies were found ex vivo, there was a trend towards greater expansion of Tregs upon TsAg stimulation in subarachnoid than in parenchymal NCC when data were normalized for the corresponding controls.T. solium infection of the subarachnoid space is associated with an enhanced regulatory immune response compared to infection in the parenchyma. The resulting anti-inflammatory milieu may represent a parasite strategy to maintain a permissive environment in the host or diminish

    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.

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

    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.

    Canine Steroid-Responsive Meningitis-Arteritis (SRMA) is a suitable animal model for studies on the development of neutrophilic pleocytosis in aseptic meningitis. Samples of dogs in the acute phase of SRMA (n=16) were examined for gene expression of matrix metalloproteinases (MMP)-2 and -9 and tissue inhibitors of metalloproteinases (TIMP)-1 and -2. Results were compared to those of dogs under glucocorticosteroid treatment for SRMA (n=16) and dogs with other inflammatory and neoplastic diseases of the central nervous system (CNS) (n=19). Samples included mononuclear (PBMCs) and polymorphonuclear cells (PBPMNs) of peripheral blood and cerebrospinal fluid white blood cells (CSF WBCs). In the acute phase of SRMA CSF WBCs showed mRNA expression for MMP-2 and -9 and TIMP-1 and -2, highlighting a contribution of these cells to the overall content of MMPs and TIMPs in CSF. MMP-2 mRNA levels in CSF WBCs were significantly up-regulated in comparison to PBMC expression levels, suggesting that MMP-2 is relevant for PBMC invasion into the subarachnoidal space and that the expression is influenced by migratory activity through the blood-CSF-barrier.

    Dengue fever(DF) and dengue haemorrhagic fever(DHF) are important mosquito-borne viral diseases of humans and recognized as important emerging infectious diseases in the tropics and subtropics. Compared to nine reporting countries in the 1950s, today the geographic distribution includes more than100 countries worldwide. Dengue viral infections are known to present a diverse clinical spectrum, ranging from asymptomatic illness to fatal dengue shock syndrome. Mild hepatic dysfunction in dengue haemorrhagic fever is usual. However, its presentation as acute liver failure(ALF)is unusual. We report a patient with dengue shock syndrome who presented with acute liver failure and hepatic encephalopathy in a recent outbreak of dengue fever in Delhi, India.

    Therapeutic hypothermia, recently termed target temperature management (TTM), is the cornerstone of neuroprotective strategy. Dating to the pioneer works of Fay, nearly 75 years of basic and clinical evidence support its therapeutic value. Although hypothermia decreases the metabolic rate to restore the supply and demand of O₂, it has other tissue-specific effects, such as decreasing excitotoxicity, limiting inflammation, preventing ATP depletion, reducing free radical production and also intracellular calcium overload to avoid apoptosis. Currently, mild hypothermia (33°C) has become a standard in post-resuscitative care and perinatal asphyxia. However, evidence indicates that hypothermia could be useful in neurologic injuries, such as stroke, subarachnoid hemorrhage and traumatic brain injury. In this review, we discuss the basic and clinical evidence supporting the use of TTM in critical care for acute brain injury that extends beyond care after cardiac arrest, such as for ischemic and hemorrhagic strokes, subarachnoid hemorrhage, and traumatic brain injury. We review the historical perspectives of TTM, provide an overview of the techniques and protocols and the pathophysiologic consequences of hypothermia. In addition, we include our experience of managing patients with acute brain injuries treated using endovascular hypothermia.

  12. Is there a role for magnetic resonance imaging in the evaluation of non-traumatic intraparenchymal haemorrhage in children?

    International Nuclear Information System (INIS)

    In contrast to adults, intraparenchymal haemorrhage (IPH) is at least as common as ischaemic stroke in children. There is often uncertainty about the most appropriate modality for imaging in the acute stage. To examine the diagnostic value of MRI and MR angiography (MRA) in the detection of underlying pathology in children with non-traumatic IPH. A retrospective review was conducted of children with IPH from January 1997 to March 2003. After exclusion of patients with traumatic IPH or previously diagnosed vascular malformation, aneurysm, or brain tumour, 50 children were identified. Case notes and imaging studies were reviewed. An underlying lesion was demonstrated with MR in two-thirds of children (25/38) with IPH. A vascular lesion was the commonest cause, followed by tumour. Three children had false-negative MR scans. MR is a valuable non-invasive imaging modality for detection of both vascular and non-vascular causes of paediatric IPH. The high rate of the latter in childhood makes incorporation of MR into paediatric IPH imaging protocols especially important. Clinical guidelines regarding the optimum sequence of investigations in non-traumatic IPH would be helpful to standardize practice and enable critical appraisal. (orig.)

    2016-07-01

    Idiopathic interstitial pneumonias (IIPs) may have an acute or subacute presentation, or acute exacerbation may occur in a previously subclinical or unrecognized chronic IIP. Acute or subacute IIPs include acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP), nonspecific interstitial pneumonia (NSIP), acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) and AE-NSIP. Interstitial lung diseases (ILDs) including connective tissue disease (CTD) associated ILD, hypersensitivity pneumonitis, acute eosinophilic pneumonia, drug-induced lung disease and diffuse alveolar haemorrhage need to be differentiated from acute and subacute IIPs. Despite the severe lack of randomized controlled trials for the treatment of acute and subacute IIPs, the mainstream treatment remains corticosteroid therapy. Other potential therapies reported in the literature include corticosteroids and immunosuppression, antibiotics, anticoagulants, neutrophil elastase inhibitor, autoantibody-targeted treatment, antifibrotics and hemoperfusion therapy. With regard to mechanical ventilation, patients in recent studies with acute and subacute IIPs have shown better survival than those in previous studies. Therefore, a careful value-laden decision about the indications for endotracheal intubation should be made for each patient. Noninvasive ventilation may be beneficial to reduce ventilator associated pneumonia. PMID:27123874

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

    International Nuclear Information System (INIS)

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

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

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

    Full Text Available Aim: Haemorrhagic cystitis (HC is uncommon and in its severe form potentially life threatening complication of Haematopoietic stem cell transplantation (HSCT in children. We present our single centre experience in the urological management of this clinically challenging condition. Patients and Methods: Fourteen patients were diagnosed with BK-Virus HC in our centre. The mean age at diagnosis was 8.8 years (range, 3.2-18.4 years. The mean number of days post-BMT until onset of HC was 20.8 (range, 1 – 51. While all patients tested urine positive for BKV at the clinical onset of HC, only four patients had viral quantification, with viral loads ranging from 97,000 to >1 billion/ml. 8 patients had clinical HC. Ten patients experienced acute GVHD (grade I: 6 patients, grade II: 3 patients, grade 4: 1 patient.Results: Four patients received medical management for their HC. Treatments included hyperhydration, MESNA, blood and platelet transfusion, premarin and oxybutynin (Table 6.  Two patients received both medical and surgical management which included cystoscopy with clot evacuation, bladder irrigation and supra-pubic catheter insertion. One patient received exclusive surgical management. Seven patients were treated conservatively. Conclusion: There is limited available evidence for other potential therapeutic strategies highlighting the need for more research into the pathophysiology of HSCT-associated HC. Commonly used interventions with possible clinical benefit (e.g. cidofovir, ciprofloxacin still require to be evaluated in multi-centre, high-quality studies. Potential future preventative and therapeutic options, such as modulation of conditioning, immunosuppression and engraftment, new antiviral and anti-inflammatory and less nephrotoxic agents need to be assessed.---------------------------Cite this article as:Vasdev N, Davidson A, Harkensee C, Slatter M, Gennery A, Willetts I, Thorpe A.Urological management (medical and surgical of BK

    Purpose: To evaluate the clinical applications of magnetic resonance imaging (MRI) in patients with acute traumatic brain injury (TBI): to identify the type, quantity, severity; and improvement clinical-radiological correlation. Method: Assessment of 55 patients who were imaged using CT and MRI, 34 (61.8%) males and 21 (38.2%) females, with acute (0 to 5 days) and closed TBI. Results: Statistical significant differences (McNemar test): occurred fractures were detected by CT in 29.1% and by MRI in 3.6% of the patients; subdural hematoma by CT in 10.9% and MRI in 36.4 %; diffuse axonal injury (DAI) by CT in 1.8% and MRI in 50.9%; cortical contusions by CT in 9.1% and MRI in 41.8%; subarachnoid hemorrhage by CT in 18.2% and MRI in 41.8%. Conclusion: MRI was superior to the CT in the identification of DAI, subarachnoid hemorrhage, cortical contusions, and acute subdural hematoma; however it was inferior in diagnosing fractures. The detection of DAI was associated with the severity of acute TBI. (author)

    Imagenological diagnosis of subarachnoid neurocysticercosis is usually difficult when classical magnetic resonance imaging (MRI) sequences are used. The purpose of this study was to evaluate the advantages of 3D MRI sequences (Fast Imaging Employing Steady-state Acquisition (FIESTA) and Spoiled Gradient Recalled Echo (SPGR)) with respect to classical sequences (Fluid Attenuation Inversion Recovery (FLAIR) and T1) in visualizing Taenia solium cyst in these locations. Forty-seven T. solium cysts located in the basal cisterns of the subarachnoid space were diagnosed in eighteen Mexican patients. A pre-treatment MRI was performed on all patients, and all four sequences (FIESTA, FLAIR, T1 SPGR, and T2) were evaluated independently by two neuroradiologists. The sensitivity of each sequence to detect the parasite membrane and scolex was evaluated, along with its capacity to detect differences in signal intensity between cerebrospinal fluid (CSF) and cysts. FIESTA sequences allowed the visualization of cyst membrane in 87.2% of the parasites evaluated, FLAIR in 38.3%, SPGR in 23.4%, and T2 in 17.0%. The superiority of FIESTA sequences over the other three imaging methods was statistically significant (P0.05). Differences in signal intensity between CSF and parasite cysts were significant in FIESTA (P<0.0001), SPGR (P<0.0001), and FLAIR (P=0.005) sequences. For the first time, the usefulness of 3D MRI sequences to diagnose T. solium cysts located in the basal cisterns of the subarachnoid space was demonstrated. The routine use of these sequences could favor an earlier diagnosis and greatly improve the prognosis of patients affected by this severe form of the disease.

    2014-01-01

    Full Text Available Background and Aims: Subarachnoid block is one of the common modes of anaesthesia opted for emergency caesarean section, if the maternal and foetal conditions are favourable. Various factors influence the quality of care administered during the procedure. This questionnaire based study was undertaken to look for self-expressed problems in peri-operative period in patients undergoing emergency caesarean surgery under subarachnoid block. Methods: All the parturients who underwent emergency caesarean section under subarachnoid block during 6 months period were distributed a questionnaire in post-operative period. They were encouraged to fill and return the form within 15 days. Patient satisfaction and the self-expressed problems were analysed at the end of 6 months. Results: One hundred and seventy five out of 220 parturients responded. 58.3% of them said that they were explained about the anaesthesia prior to surgery and 85.3% overall remained anxious. With people around them, 93.1% of them felt comfortable and 91.4% expressed that they were made comfortable inside the theatre. The self-expressed problems were shivering (43.4%, breathlessness (21.7%, pain (20%, post-operative headache (15.4% and backache (19.4%. Parturients who heard their babies cry was 85.1%. After their babies were shown after delivery, 77.1% mothers slept well; 86.9% fed their babies within 4 h of delivery. Conclusion: Pre-operative communication in emergency caesarean section by health personnel did not reduce the anxiety level, which shows that communication was ineffective. Intra-operative psychological support like making the patient comfortable, showing baby to mother and early breast feeding improve bonding between child and mother and essentially contribute to patient satisfaction.

    Objectives: Aneurysmal subarachnoid hemorrhage often leads to death and poor clinical outcome. Injury occurring during the first 72 hours is termed “early brain injury,” with disruption of the nitric oxide pathway playing an important pathophysiologic role in its development. Quantitative electroencephalographic variables, such as α/δ frequency ratio, are surrogate markers of cerebral ischemia. This study assessed the quantitative electroencephalographic response to a cerebral nitric oxide donor (intravenous sodium nitrite) to explore whether this correlates with the eventual development of delayed cerebral ischemia. Design: Unblinded pilot study testing response to drug intervention. Setting: Neuroscience ICU, John Radcliffe Hospital, Oxford, United Kingdom. Patients: Fourteen World Federation of Neurosurgeons grades 3, 4, and 5 patients (mean age, 52.8 yr [range, 41–69 yr]; 11 women). Interventions: IV sodium nitrite (10 μg/kg/min) for 1 hour. Measurements and Main Results: Continuous electroencephalographic recording for 2 hours. The alpha/delta frequency ratio was measured before and during IV sodium nitrite infusion. Seven of 14 patients developed delayed cerebral ischemia. There was a +30% to +118% (range) increase in the alpha/delta frequency ratio in patients who did not develop delayed cerebral ischemia (p < 0.0001) but an overall decrease in the alpha/delta frequency ratio in those patients who did develop delayed cerebral ischemia (range, +11% to –31%) (p = 0.006, multivariate analysis accounting for major confounds). Conclusions: Administration of sodium nitrite after severe subarachnoid hemorrhage differentially influences quantitative electroencephalographic variables depending on the patient’s susceptibility to development of delayed cerebral ischemia. With further validation in a larger sample size, this response may be developed as a tool for risk stratification after aneurysmal subarachnoid hemorrhage. PMID:27441898

    Cerebral vasospasm (CV) after subarachnoid hemorrhage (SAH) is a devastating and unsolved clinical issue. In this study, the rat models, which had been induced SAH by prechiasmatic cistern injection, were treated with melatonin. Synchrotron radiation angiography (SRA) was employed to detect and evaluate CV of animal models. Neurological scoring and histological examinations were used to assess the neurological deficits and CV as well. Using SRA techniques and histological analyses, the anterior cerebral artery diameters of SAH rats with melatonin administration were larger than those without melatonin treatment (p experimental SAH.

    Carotid-basilar anastomoses are remnants of the fetal circulation and although rare, they may become symptomatic and should be recognized during cerebral angiography. Two patients are described with non-aneurysmal subarachnoid hemorrhage and persistent trigeminal arteries (PTA) found on cerebral angiography. In the first patient, the PTA ended in the anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery. The second patient had a PTA terminating in the AICA and superior cerebellar artery. These rare anatomical PTA variants should be recognized on cerebral angiography. PMID:21990842

    The authors present the first reported case of a glioma associated with a right posterior cerebral artery (PCA) aneurysm. A 37-year-old male underwent craniotomy and total removal of the glioma, which appeared, according to encephalographic findings, to be responsible for the initial symptom of loss of consciousness. The risk of craniotomy-induced bleeding from the aneurysm was thought to be low, since it was unruptured and was packed with coagulum. However, subarachnoid hemorrhage due to rupture of the PCA aneurysm occurred just after craniotomy, and clipping was performed 15 days after the first operation. PMID:2480546

    Statins could have physiologic properties that may beneift patients that have been diagnosed with various acute neurological diseases. This review aims tosummarize the literature pertaining to stain use in acute neurological disease such as subarachnoid hemorrhage, intracerebral hemorrhage (ICH), cerebral ischemia (CI), traumatic brain injury, status epilepticus and meningitis. The authors reviewed published abstracts and manuscripts pertaining to experimental and clinical trials relevant to statins in acute neurological disease. Although acute statin therapy in the setting of subarachnoid hemorrhage might reduce delayed cerebral ischemia and mortality, it should not be considered standard care at this time. Acute statins therapy has not demonstrated anybeneift yet folowing an ICH or CI. Acute statin withdrawal may worsen outcome in acute CI. Observational and case-control studies suggest that pretreatment with statin at time of onset may be associated with better outcomes. Even though preclinical studies have shown statins to have beneifcial effects, there has been no clinical evidence. In conclusion, current published studies have not shown that acute statin therapy has any beneifcal effects in acute neurologic diseases and therefore further large randomized clinical trials are needed.

    The presence of sulcal hyperdensity in patients after endovascular procedures is not necessarily attributable to hemorrhage. It may frequently indicate the absolute or concomitant extravasation of contrast material into the subarachnoid spaces. This case report describes the clinical case of an 84-year-old patient with 90% stenosis of the right internal carotid who presented with a diffuse gyral and sulcal hyperdensity in the right temporal-occipital and frontal lobes at routine post-carotid stenting (CAS) brain CT scan. The patient was asymptomatic and CT findings were interpreted as contrast enhancement hyperattenuation and no therapeutic decisions were made. A 24-hour follow-up brain CT demonstrated the complete resolution of the hyperdensity, confirming the diagnosis. In this patient we considered the concomitant presence of gyral and sulcal hyperdensity as the consequence of reversible damage to the blood-brain barrier (BBB) determining a transitory extravasation of contrast material. Asymptomatic gyral and subarachnoid contrast enhancement following CAS is generally indicative of benign and transitory damage to the BBB and is not to be misinterpreted as hemorrhage. PMID:25923674

    Thunderclap headache is a sudden and severe headache that can occur after an aneurysmal subarachnoid hemorrhage (SAH). Subarachnoid hemorrhage is a medical emergency that requires prompt attention and hospitalization. Patients with thunderclap headache often undergo a noncontrast head computed tomography (CT) scan to ascertain SAH bleeding and, if the scan is negative, then undergo a lumbar puncture to look for cerebrospinal fluid (CSF) red blood cells (RBCs), which would be consistent with an aneurysmal leak. If the initial CT is negative and CSF is positive for RBCs, patients are usually admitted to the hospital for evaluation of intracranial aneurysm. We encountered a patient with thunderclap headache whose initial head CT was negative for SAH and whose CSF tested positive for RBCs. The patient was referred to our center for evaluation and management of aneurysmal SAH. However, on careful review of the patient's medical history, serum laboratory values, and spinal fluid values, the patient was diagnosed with Ehrlichia chaffeensis meningitis. While Ehrlichia meningitis is rare, it is important to recognize the clinical clues that could help avoid formal cerebral angiography, a costly and potentially unnecessary procedure. We present how this case represented a cognitive framing bias and anchoring heuristic as well as steps that medical providers can use to prevent such cognitive errors in diagnosis. PMID:27053985

    1981-02-01

    Full Text Available Thirteen patients exhibited a communicating hydrocephalus following subarachnoid hemorrhage secondary to ruptured intracranial aneurysms and were treated with shunt procedures. The interval between subarachnoid hemorrhage and surgery averaged 9 weeks. Seven of the patients showed improvement. The prognostic value for surgical management was evaluated on the basis of three different diagnostic examinations (computed tomography(CT, cisternography and constant infusion test. A correct diagnosis was obtained in 78 per cent in cisternography, and 63 per cent in infusion test and CT. All patients responding to surgery showed a typical pattern in cisternography, consisting of ventricular retention of radiopharmaceutical tracer for 48 h or longer in association with no radioactivity over the cerebral hemispheres. The constant infusion test correlated well with typical cisternographic patterns. CT is useful in demonstrating pathophysiological changes in hydrocephalus. Periventricular hypodensity was visible in patients with normal or slightly elevated intracranial pressure, accompanied by fairly rapid deterioration. All of them responded well to shunting. In most cases which benefited from the shunt, the postoperative CT showed not only normal-sized ventricles but also marked regression of the hypodensity over a short period.

This study investigated whether postoperative cisternal CSF drainage affects the incidence of cerebral vasospasm and clinical outcome in patients with thin SAH. Seventy-eight patients with thin SAH, 22 men and 56 women aged from 17 to 73 years (mean 51.2 years, underwent surgical repair for ruptured anterior circulation aneurysm. Patients were divided into groups with (38 patients and without (40 patients postoperative cisternal CSF drainage, and the incidences of angiographical and symptomatic vasospasm, shunt-dependent hydrocephalus, meningitis, and the clinical outcome were compared. The incidences of angiographical vasospasm (31.6% vs 50.0%, symptomatic vasospasm (7.9% vs 12.5%, shunt-dependent hydrocephalus (5.3% vs 0%, and meningitis (2.6% vs 0% did not differ between patients with and without cisternal CSF drainage. All patients in both groups resulted in good recovery. Postoperative cisternal CSF drainage does not affect the incidence of cerebral vasospasm or the clinical outcome in patients with thin SAH.Keywords: subarachnoid hemorrhage; cerebrospinal fluid drainage; cerebral vasospasm; meningitis; hydrocephalus; ruptured intracranial aneurysm

    Posterior reversible encephalopathy syndrome (PRES) is an uncommon but significant complication of hemodynamic therapy after aneurysmal subarachnoid hemorrhage (aSAH)-induced vasospasm. We performed a PubMed literature search for the period January 1999 to January 2015 using the search terms "posterior reversible encephalopathy syndrome", "subarachnoid hemorrhage", "vasospasm", and "hypertensive encephalopathy", and identified nine cases of PRES after aSAH-induced vasospasm in the literature. We also present a 63-year-old man with aSAH complicated by vasospasm treated with hemodynamic augmentation who subsequently developed PRES. Imaging following development of PRES symptoms shows vasogenic edema in the white matter of the parietal and occipital lobes. Age, sex, history of hypertension, and baseline blood pressure were variable among patients in the literature review. In all cases, patients improved both from a radiological and clinical perspective following blood pressure reduction. To summarize, PRES is a rare complication of hemodynamic therapy for vasospasm following aSAH. The literature at the time of writing demonstrates no common pattern with regard to patient demographics, medical history, or mode of treatment for symptomatic vasospasm. Given its sporadic and unpredictable nature, considering PRES in the differential diagnosis is important when addressing neurological decline following hemodynamic treatment of vasospasm related to aSAH.

    The spontaneous disappearance and reappearance of a ruptured cerebral aneurysm is generally assumed to be a rare phenomenon although the actual incidence is unknown. Among 39 consecutive cases of acute subarachnoid hemorrhage (SAH), 33 were studied by three-dimensional computed tomographic angiography (CTA) within 6 h after the onset of SAH, followed by digital subtraction angiography (DSA) within 24 h after the ictus. Of those patients, one, a 58-year-old woman, had a saccular aneurysm at the distal anterior cerebral artery; the aneurysm was clearly demonstrated by CTA 2.5 h after the SAH onset, but was not shown by a subsequent DSA performed 8.5 h after the ictus. A follow-up DSA detected the neck of aneurysm on day 11, and the whole aneurysm was visualized on day 19. The observations in this particular case suggest that the spontaneous disappearance of a ruptured cerebral aneurysm may occur during the ultra-early stage of SAH and that reappearance may follow during the next few weeks. The patient did not suffer complications such as vasospasm or systemic hypotension nor was she treated with antifibrinolytic agents. The aneurysmal shape and the surrounding clot are considered as putative factors possibly related to the intermittent appearance of the aneurysm. PMID:11045020

    recorded in a standard chart. The patients were managed according to a standard protocol guided by the ICP levels. There were no intracranial haemorrhagic complications or hematomas due the monitoring method. Sixty six patients were punctured by lateral C1-C2 technique to assess infectious complications and 2 had positive cerebrospinal fluid samples for Acinetobacter sp. The final results measured at hospital discharge showed 75 deaths (36,40% and 131 (63,60% survivors. ICP levels had significantly influenced the final results (p<0,001. The subarachnoid method to continuously assess the ICP levels was considered aplicable, safe, simple, low cost and useful to advise the management of the patients. The ICP record methodology was practical and useful. Despite the current technical advances the subarachnoid method was considered viable to assess the ICP levels in severe head injury.

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

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

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

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

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

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

    2014-01-01

    Ebola zoonotic RNA filovirus represents human most virulent and lethal pathogens, which induces acute hemorrhagic fever and death within few days in a range of 60-90% of symptomatic individuals. Last outbreak in 2014 in West Africa caused panic that Ebola epidemic can be spread to other continents. Number of deaths in late December reached almost 8,000 individuals out of more than 20,000 symptomatic patients. It seems that only a coordinated international response could counteract the further spread of Ebola. Major innate immunity mechanisms against Ebola are associated with the production of interferons, that are inhibited by viral proteins. Activation of host NK cells was recognized as a leading immune function responsible for recovery of infected people. Uncontrolled cell infection by Ebola leads to an impairment of immunity with cytokine storm, coagulopathy, systemic bleeding, multi-organ failure and death. Tested prevention strategies to induce antiviral immunity include: i. recombinant virus formulations (vaccines); ii. cocktail of monoclonal antibodies (serotherapy); iii. alternative RNA-interference-based antiviral methods. Maintaining the highest standards of aseptic and antiseptic precautions is equally important. Present brief review summarizes a current knowledge concerning pathogenesis of Ebola hemorrhagic disease and the virus interaction with the immune system and discusses recent advances in prevention of Ebola infection by vaccination and serotherapy.

  17. INFLUENCE OF INTRAVENOUS DEXMEDETOMIDINE INFUSION ON SUBARACHNOID BLOCK WITH BUPIVACAINE IN ADULT INGUINAL HERNIORRHAPHIES

    Directory of Open Access Journals (Sweden)

    Suhara

    2014-09-01

    Full Text Available INTRODUCTION: Central neuraxial blocks with local anaesthetics are popular techniques of anaesthesia which have been extensively used for lower abdominal surgery. Subarachnoid block is a simple technique which requires a small dose of local anaesthetic to provide rapid and reliable surgical anaesthesia and minimal risk of drug toxicity. Duration of spinal anaesthesia may be prolonged by addition of opioids, clonidine, neostigmine, or vasoconstrictor agents to the local anesthetic drug for better post-op pain relief. Intrathecal addition of a low dose of α2-agonist like clonidine or dexmedetomidine results in significant prolongation of the duration of the sensory and motor blockade induced by hyperbaric bupivacaine. This study is designed to investigate the effects of intravenous dexmedetomidine on the duration of sensory and motor blockade induced by intrathecal administration of bupivacaine, and its associated adverse events. AIMS AND OBJEVCTIVES: To determine effect of intravenous Dexmedetomidine on the duration of analgesia with spinal Bupivacaine for adult patients undergoing herniorrhaphy and to assess the incidence of intra operative side effects, if any. STUDY SETTING: This study was done under the department of Anaesthesiology, Azeezia Medical College from March 2013 to October 2013. STUDY DESIGN: A double blind prospective randomized control study was done.50 adults aged 20 to 60 years scheduled for herniorrhaphies were allocated into two study groups, named A and B using computer generated randomization. INTERPRETATIONS AND CONCLUSION: The duration of analgesia of subarachnoid block with heavy 0.5% bupivacaine with intravenous infusion of saline and dexmedetomidine were compared. Post-operative pain was evaluated by Visual Analogue Scale. Duration of analgesia is the time taken from the administration of the drug to the time when the patient complains of pain of > 50 in Visual Analogue Scale. The duration of analgesia was longest in

    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.

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

    2012-01-01

    Full Text Available Severe complications that develop in the early stages in patients with acute leukemia have a mortal course. Bleeding, leukostasis, and less frequently, infections are responsible for early mortality. Hemorrhage is most common in acute leukemia and usually leads to death. Hemorrhage may occur due to chemotherapy or bone marrow transplantation in patients with acute leukemia. Leukocytosis, thrombocytopenia, sepsis, and coagulopathy increase the risk of bleeding. There may be multiple etiologic factors. Subdural or subarachnoid hemorrhage is less common than an intra-axial hemorrhage. The incidence of spontaneous subdural hematoma is higher in patients with leukemia. Although advances in the treatment of platelet transfusion and disseminated intravascular coagulation have decreased the incidence of hemorrhagic complications in patients receiving chemotherapy for acute leukemia, intracranial hemorrhage-related deaths are a significant problem. We discussed the etiology and management of chronic subdural hematoma detected in a two-year-old male patient with Acute Myeloid Leukemia and hyperleukocytosis.

  2. A Hypothesis: Hydrogen Sulfide Might Be Neuroprotective against Subarachnoid Hemorrhage Induced Brain Injury

    Directory of Open Access Journals (Sweden)

    Yong-Peng Yu

    2014-01-01

    Full Text Available Gases such as nitric oxide (NO and carbon monoxide (CO play important roles both in normal physiology and in disease. Recent studies have shown that hydrogen sulfide (H2S protects neurons against oxidative stress and ischemia-reperfusion injury and attenuates lipopolysaccharides (LPS induced neuroinflammation in microglia, exhibiting anti-inflammatory and antiapoptotic activities. The gas H2S is emerging as a novel regulator of important physiologic functions such as arterial diameter, blood flow, and leukocyte adhesion. It has been known that multiple factors, including oxidative stress, free radicals, and neuronal nitric oxide synthesis as well as abnormal inflammatory responses, are involved in the mechanism underlying the brain injury after subarachnoid hemorrhage (SAH. Based on the multiple physiologic functions of H2S, we speculate that it might be a promising, effective, and specific therapy for brain injury after SAH.

    2014-01-01

    Background: Isolated cervical anterior spinal artery aneurysms are extremely rare. Subarachnoid hemorrhage (SAH) secondary to such lesions have been described only in six cases to the best of our knowledge. Case Description: We describe an unusual clinical picture of SAH due to rupture of anterior spinal artery aneurysm in a patient with previous normal angiogram. Due to the location of the aneurysm and clinical status of the patient, conservative management was proposed, and she was discharged to further follow-up. Monthly routine angiograms revealed resolution of the aneurysm 90 days after bleeding, which was highly suggestive of vascular dissection. Conclusion: We highlight the need to consider these aneurysms in the differential diagnosis of SAH, especially when occurring in the posterior fossa and when angiography findings are inconclusive.

    Neurogenic pulmonary edema (NPE) is a potentially catastrophic but treatable systemic event after subarachnoid hemorrhage (SAH). The development of NPE most frequently occurs immediately after SAH, and the severity is usually self-limiting. Despite extensive research efforts and a breadth of collective clinical experience, accurate diagnosis of NPE can be difficult, and effective hemodynamic treatment options are limited. Recently, a bedside transpulmonary thermodilution device has been introduced that traces physiological patterns consistent with current theories regarding the mechanism (hydrostatic or permeability PE) of NPE. This article provides an overview of the clinical usefulness of the advanced technique for use in the neurointensive care unit for the diagnosis and management of post-SAH NPE.

  6. Intra-arterial colforsin daropate for the treatment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage

    International Nuclear Information System (INIS)

    Cerebral vasospasm (CV) remains a major cause of mortality and morbidity in patients with subarachnoid hemorrhage (SAH). Here, we examined the effectiveness and safety of intra-arterial injection of colforsin daropate hydrochloride (CDH). A consecutive series of 29 patients with angiographically confirmed CV received intra-arterial CDH (IAC) therapy. Angiographic changes in spastic vessels and the cerebral circulation time (CCT) were assessed before and after IAC treatment, together with the change in clinical status. IAC treatment was performed in 53 procedures in 29 patients. Angiographic improvement was observed following all procedures (100%), and clinical improvement was observed following 36 of 42 procedures (86%) in symptomatic cases. CCT improved significantly. At the 3-month follow-up, 19 patients (66%) showed good recovery or moderate disability on the Glasgow Outcome Scale. Major adverse effects were headache and increased heart rate. IAC treatment was effective and safe for the treatment of CV after SAH. (orig.)

    Full Text Available Nervous system injuries associated with epidemic hemorrhagic fever (EHF are not rarely seen. However, cerebrovascular disease arising from EHF is rarely reported in the literature. A 50-year-old male patient suffered from subarachnoid hemorrhage (SAH. No abnormal condition was found in intracranial vascular digital subtraction angiography (DSA. But, this patient presented with positive hantavirus-IgM and IgG, with typical clinical process, which lead to the diagnosis of EHF followed by SAH. To our knowledge, SAH associated with EHF has not been previously reported. A meticulous assessment of EHF patients with a serious condition had one or more central nervous system (CNS abnormalities, such as sudden headache, vomiting, confusion, meningismus, and convulsions, which is necessary for diagnosing and giving timely treatment to improve the prognosis.

    OBJECT: The authors investigated early changes in the cerebral arteries of rats that occur after subarachnoid hemorrhage (SAH). METHODS: Messenger RNA was investigated by performing microarray and quantitative real-time polymerase chain reaction (PCR) analyses, and protein expression was shown...... by performing immunohistochemical studies. The array data indicated that the initial processes that occur after SAH involve activation of genes involved in angiogenesis, inflammation, and extracellular matrix (ECM) remodeling. The real-time PCR investigation confirmed upregulation of genes that were observed...... using the microarray to be regulated, including iNOS, MMP13, and cxcl2. The authors also verified the upregulation of previously implicated genes for G-protein-coupled receptors (endothelin B [ETB], angiotensin 1 [AT1], and AT2) and metalloproteinase 9.

    Full Text Available Spontaneous subarachnoid hemorrhage is the most common neurological disorder leading to pre-hospital cardiac arrest. ECG changes in SAH may mimic myocardial infarction or ischemia, and thus lead to delayed treatment of the primary problem. Early identification of SAH-induced cardiac arrest with the use of computed tomography scan of the brain obtained immediately after resuscitation will aid emergency physicians make further decisions. The overall prognosis of patients who are resuscitated is extremely poor. But, prompt neurosurgical referral and multidisciplinary intensive care management can improve the survival rate and the functional outcome. Thus, physicians should consider SAH as a differential diagnosis in patients presenting with pre-hospital cardiac arrest.

    Acute vasospasm of the transclivally exposed basilar artery of anesthetised cats was produced by the subarachnoid injection of platelet-rich plasma (PRP) treated with enough adenosine diphosphate (ADP) to induce platelet aggregation and secretion. Vasorelaxation was produced by the topical application of the calcium antagonist verapamil. Changes in the internal diameter of the basilar artery were determined by measuring the blood column diameter from photomicrographs taken sequentially, at 5 minute intervals, through the operating microscope. Changes in blood vessel diameter are expressed as a plus or minus percentage of the pretreatment diameter. Arterial blood pressure and blood gas values were kept in the physiological range for the cat. The subarachnoid injection of PRP-ADP produced severe constriction of the basilar artery (mean constriction at 5 minutes after injection: -40.7% +/- 2.8 SEM). Platelet-free plasma, ADP alone and Elliott's A solution had no spasmogenic effect when injected into the subarachnoid space. The topical application of the calcium channel blocker verapamil (0.1 mg per kg) 30 minutes after the injection of PRP-ADP, with the basilar artery still in spasm (mean constriction: -23% +/- 3.5 SEM), produced prompt and dramatic vasodilation (mean dilation at 5 minutes after application: +52.7% +/- 18.1 SEM). This spasmolytic effect persisted in a decremental fashion for the 60 minute period of observation, by which time the previously constricted vessel had returned to its normal size. These observations indicate that the platelet fraction of whole blood may be involved in the genesis of acute vasospasm following subarachnoid hemmorrhage and that this phenomenon can be readily reversed by calcium antagonism.

    Dynamic perfusion computed tomography (PCT) has been established as a diagnostic instrument for the detection of vasospasm after subarachnoid hemorrhage (SAH). The purpose of this study was to assess the prognostic impact of PCT parameters after SAH on the long-term outcome of patients. Three hundred twelve patients were retrospectively interrogated with a questionnaire 23.06 {+-} 14.33 months after spontaneous subarachnoid hemorrhage. The modified Rankin scale (mRS) was determined, respectively. Scheduled PCT data sets from the first days after ictus were available for all patients. The maximum mean transit time over several examinations per hemisphere (MTT{sub PEAK}) values were significantly correlated (p {<=} 0.001, r = 0.422) with the clinical long-term outcome (mRS). Corresponding to our linear regression analysis, MTT{sub PEAK} is the second most important regressor (behind clinical severity of the initial hemorrhage) for the prediction of long-term mRS. An MTT{sub PEAK} threshold of 3.98 s (identified by receiver operating characteristic analysis, area under the curve = 0.75) predicted an unfavorable long-term outcome (mRS {>=} 2) with a sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of 67.3, 74.3, 84.5, 52.1, and 69.6 %, respectively. The presented data corroborate the relevance of PCT data for the clinical long-term outcome of SAH patients. By identification of patients who are at risk for a bad outcome and may need escalation of therapy, risk-benefit analysis is supported. (orig.)

    Full Text Available Subarachnoid hemorrhage (SAH is a particularly devastating type of stroke which is responsible for one third of all stroke-related years of potential life lost before age 65. Surgical treatment has been shown to decrease both morbidity and mortality after subarachnoid hemorrhage. We hypothesized that payer status other than private insurance is associated with lower allocation to surgical treatment for patients with SAH and worse outcomes.We examined the association between insurance type and surgical treatment allocation and outcomes for patients with SAH while adjusting for a wide range of patient and hospital factors. We analyzed the Nationwide Inpatient Sample hospital discharge database using survey procedures to produce weighted estimates representative of the United States population.We studied 21047 discharges, representing a weighted estimate of 102595 patients age 18 and above with a discharge diagnosis of SAH between 2003 and 2008.Multivariable logistic and generalized linear regression analyses were used to assess for any associations between insurance status and surgery allocation and outcomes.Despite the benefits of surgery 66% of SAH patients did not undergo surgical treatment to prevent rebleeding. Mortality was more than twice as likely for patients with no surgical treatment compared to those who received surgery. Medicare patients were significantly less likely to receive surgical treatment.Nearly two thirds of patients with SAH don't receive operative care, and Medicare patients were significantly less likely to receive surgical treatment than other patients. Bias against the elderly and those with chronic illness and disability may play a part in these findings. A system of regionalized care for patients presenting with SAH may reduce disparities and improve appropriate allocation to surgical care and deserves prospective study.

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

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

    Full Text Available The use of intravenous thrombolytic agents has revolutionised the treatment of acute myocardial infarction. However, the improvement in mortality rate achieved with these drugs is tempered by the risk of serious bleeding complications, including intracranial haemorrhage. Tenecteplase is a genetically engineered mutant tissue plasminogen activator. Haemorrhagic complications of tissue plasminogen activator (tPA are well known. Compared to other tPAs, tenecteplase use leads to lower rates of bleeding complications. Here, we report a case of unusual site of spontaneous bleeding, intralingual haematoma during tenecteplase therapy following acute myocardial infarction, which caused significant upper airway obstruction and required tracheotomy to maintain the patient’s airway. Clinical dilemmas related to securing the airway or reversing the effects of tissue plasminogen activator are discussed.
