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

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

    OBJECTIVE: To estimate the risk of occurrence of subarachnoid haemorrhage in first degree relatives (parents, siblings, children) of patients with subarachnoid haemorrhage. DESIGN: Population based cohort study using data from the Danish National Discharge Registry and the Central Person Registry......, standardised for age, sex, and calendar period. This process was repeated for patients discharged from neurosurgery units, as diagnoses from these wards had high validity (93%). RESULTS: 18 patients had a total of 19 first degree relatives with subarachnoid haemorrhage during the study period, corresponding...... to a standardised incidence ratio of 2.9 (95% confidence interval 1.9 to 4.6). Patients discharged from neurosurgery wards had a higher standardised incidence ratio (4.5, 2.7 to 7.3). CONCLUSIONS: First degree relatives of patients with subarachnoid haemorrhage have a threefold to fivefold increased risk...

    Over the past decade, significant advances have been made in the field of subarachnoid haemorrhage (SAH). Prompt diagnosis with high-resolution CT and intensive critical care support remain key aspects of good patient management. Early identification and definitive treatment of underlying ruptured aneurysms is generally advocated to reduce the risk of re-bleeding, a complication with high mortality and morbidity. Although intra-arterial digital subtraction angiography (DSA) is still considered the gold standard for sourcing aneurysms, CT angiography, especially with the evolution of multi-slice technology, is slowly gaining acceptance as a rapid, accessible and minimally invasive method which appears likely to replace DSA as first-line modality in the future. Furthermore, the advent of Guglielmi detachable coils and the ISAT trial have revolutionised the treatment of ruptured aneurysms, with a significant trend towards endovascular coiling away from operative clipping. Improvements in clinical experience, coiling technology and assistive devices now allow interventionalists to potentially treat the majority of aneurysms, including wide-necked or complex lesions. The uncertain long-term results of coiling, however, still fuel strong debate and controversy. This review summarises current diagnostic approaches to SAH from a radiological perspective, with an emphasis on aneurysmal SAH and an evidence-based approach to the role of imaging and interventional radiology in diagnosis, treatment and follow-up.

    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.

    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

    2012-10-01

    Spontaneous occlusion is a rare manifestation of ruptured vertebral artery dissection (VAD). Its natural history and treatment strategy have yet to be established due to its rarity. Here, we report five lesions involving spontaneous occlusion of VAD after subarachnoid haemorrhage, among which three lesions showed recanalisation. Based on our experience and previous reports, spontaneous occlusion of ruptured VAD can be classified into two groups-one group with occlusion in the acute stage with a high incidence of recanalisation and another group with occlusion in the chronic stage with a relatively low incidence of recanalisation. The underlying mechanism is likely different in each group, and treatment strategies should also be tailored depending on the pathophysiology.

    Full text: Our presentation is intended to analyze our experience over the last two years, in the expeditious work up of patients with subarachnoid haemorrhage, as well as patients whose clinical symptoms combined with radiological findings are highly suspicious of an aneurysm, acute arterial occlusion, cerebral vascular malformation, venous occlusion, dissection of the internal carotid artery or vertebral artery. 276 CT Angiographies of the brain have been performed and recorded over the last two years in our Department, on a 16 Detector Philips MX8000IDT Computed Tomograph. The patients are referred to our Department from the Emergency Department of our Hospital, as well as from Hospitals all over Northwestern Greece. The CT Angiographies are performed with examination protocols, which we will analyze thoroughly in our presentation. The primary data are then studied in workstations away from the main console of the Computed Tomograph. The study of the primary data consists in multiplanar reconstructions with the Maximum Intensity Algorithm, as well as Volume Rendering and three Dimensional Reconstruction. The stages we follow for these procedures will be presented as well as the procedures for the removal of bone structures, with the intention of the best possible angiographic results. Of the 276 patients 40 were diagnosed with an aneurysm,19 with a venous angioma, 2 with a vascular malformation, 3 with venous occlusion and 2 with dissection, a total of 66/276 with aneurysms and vascular malformations. These patients were subsequently referred to the Neurosurgery Clinic or to the Department of Interventional Radiology for further treatment. The remaining 210 patients, underwent in the following days of their hospitalization a Digital Subtraction Angiography, and in 16 (7.6%) of them a small aneurysm, 3-5 mm was diagnosed. The aneurysm was detected in a second reading of the CT Angiography in 8 patients (3.8%). The CT Angiography in patients with subarachnoid

    Haemorrhages into the subarachnoid space often lead to instant blocking of the liquor circulation pathways with an acute increase of the intracranial pressure and acute venticular enlargement. These liquor circulation disturbances may be diagnosed by liquor scintiscanning as well as by pneumoencephalography. 165 patients were examined by both methods. The following results were obtained: liquor circulation disturbances after subarachnoid bleeding are frequent, they should be expected in 33% of all cases after spontaneous subarachnoid haemorrhages and in 68% of the cases after traumatic subarachnoid haemorrhages. The most severe form of liquor circulation distrubance may also be diagnosed by liquor scintiscanning as well as by pneumoencephalography. Liquor scintiscanning is the more exact method in cases with transitory ventricular reflux, while lumbar pneumoencephalography, in this series, is the method of choice when it comes to documenting the extent of the hydrocephalus.

    Full Text Available Objective. The aim of the present study is to typify BAEPs configurations of patients with different location of lesions caused by subarachnoid haemorrhage (SAH and the ensuing complications, in view of assessing the auditory-brainstem system disturbance.Methods. The typization was performed by comparing BAEPs with standard patterns from two sets of types of BAEPs by ipsilateral and binaural stimulation and by cross-stimulation.Results. 94 BAEPs were used for collection of normal referential values: for the absolute latencies and the absolute amplitudes of waves I, II, III, IV and V; for inter-peak latencies I-III, II-III, III-V, I-V and II-V; for amplitude ratios I/V and III/V. 146 BAEPs of patients with mild SAH and 55 from patients with severe SAH, were typified. In 5 types of BAEPs out of a total of 11, the percentage of the potentials in patients with mild SAH and severe SAH differed significantly (p<0.01.Conclusions. The use of sets of types of BAEPs by ipsilateral, binaural and cross-stimulation correctly classifies the potentials in patients with mild and severe SAH.

    Aim: To determine the negative predictive value of 16 channel multisection computed tomography angiography (CTA) for detecting aneurysms in spontaneous subarachnoid haemorrhage (SAH), using digital subtraction angiography (DSA) as the reference standard. Materials and methods: The prospectively collected cerebral angiogram database of Department of Neuroradiology, Atkinson Morley Regional Neuroscience Centre was used to identify 200 consecutive patients who had undergone DSA for SAH. Of these, 176 had undergone CTA prior to DSA. Clinical details and radiology reports were correlated and images of positive investigations reviewed. Results: DSA showed one or more cerebral aneurysms in 105 (60%) patients. These were correctly reported on CTA in 100. CTA was reported negative for aneurysms in 74 patients. Of these five were false negative and had aneurysms detected on DSA. In the CTA/DSA negative group, 11 (16%) patients had classical perimesencephalic clinical syndrome and blood distribution. There were two false positives at CTA. For ruptured cerebral aneurysms, CTA had 95.2% sensitivity, 97.2% specificity, 98.1% positive predictive value, and 93.2% negative predictive value. Conclusion: The sensitivity and negative predictive value of CTA for ruptured aneurysms remains imperfect. Continued use of DSA is recommended in most patients with a negative CTA after acute SAH. Confirmation of a negative CTA result with DSA may not be routinely required in patients with perimesencephalic syndrome

    The overall incidence of aneurysmal subarachnoid haemorrhage (aSAH) in western populations is around 9 per 100 000 person-years, which confers to a lifetime risk of around half per cent. Risk factors for aSAH are usually expressed as relative risks and suggest that absolute risks vary considerably according to risk factor profiles, but such estimates are lacking. We aimed to estimate incidence and lifetime risks of aSAH according to risk factor profiles. We used data from 250 patients admitted with aSAH and 574 sex-matched and age-matched controls, who were randomly retrieved from general practitioners files. We determined independent prognostic factors with multivariable logistic regression analyses and assessed discriminatory performance using the area under the receiver operating characteristic curve. Based on the prognostic model we predicted incidences and lifetime risks of aSAH for different risk factor profiles. The four strongest independent predictors for aSAH, namely current smoking (OR 6.0; 95% CI 4.1 to 8.6), a positive family history for aSAH (4.0; 95% CI 2.3 to 7.0), hypertension (2.4; 95% CI 1.5 to 3.8) and hypercholesterolaemia (0.2; 95% CI 0.1 to 0.4), were used in the final prediction model. This model had an area under the receiver operating characteristic curve of 0.73 (95% CI 0.69 to 0.76). Depending on sex, age and the four predictors, the incidence of aSAH ranged from 0.4/100 000 to 298/100 000 person-years and lifetime risk between 0.02% and 7.2%. The incidence and lifetime risk of aSAH in the general population varies widely according to risk factor profiles. Whether persons with high risks benefit from screening should be assessed in cost-effectiveness studies.

  7. Chronic hypopituitarism is uncommon in survivors of aneurysmal subarachnoid haemorrhage.

    The incidence of hypopituitarism after aneurysmal subarachnoid haemorrhage (SAH) is unclear from the conflicting reports in the literature. As routine neuroendocrine screening for hypopituitarism for all patients would be costly and logistically difficult, there is a need for precise data on the frequency of hypopituitarism and on factors which might predict the later development of pituitary dysfunction. We aimed to: (i) Establish the incidence of long-term hypopituitarism in patients with aneurysmal SAH. (ii) Determine whether data from patients' acute admission with SAH could predict the occurrence of long-term hypopituitarism. One hundred patients were studied prospectively from the time of presentation with acute SAH. Plasma cortisol, plasma sodium and a variety of clinical and haemodynamic parameters were sequentially measured for the first 12 days of their acute admission. Forty-one patients then underwent dynamic pituitary testing at median 15 months following SAH (range 7-30 months), with insulin tolerance test (ITT) or, if contraindicated, a glucagon stimulation test (GST) plus short synacthen test (SST). If symptoms of cranial diabetes insipidus (CDI) were present, a water deprivation test was also performed. Forty-one patients attended for follow-up dynamic pituitary testing. Although 14 of 100 had acute glucocorticoid deficiency immediately following SAH, only two of 41 had long-term adrenocorticotrophic hormone (ACTH) deficiency and four of 41 had growth hormone (GH) deficiency. None were hypothyroid or gonadotrophin deficient. None had chronic CDI or hyponatraemia. There was no association between acute glucocorticoid deficiency, acute CDI or acute hyponatraemia and long-term pituitary dysfunction. Both anterior and posterior hypopituitarism are very uncommon following SAH and are not predicted by acute clinical, haemodynamic or endocrinological parameters.

    Concern has been expressed about the applicability of the findings of the International Subarachnoid Aneurysm Trial (ISAT) with respect to the relative effects on outcome of coiling and clipping. It has been suggested that the findings of the National Study of Subarachnoid Haemorrhage may have greater relevance for neurosurgical practice. The objective of this paper was to interpret the findings of these two studies in the context of differences in their study populations, design, execution and analysis. Because of differences in design and analysis, the findings of the two studies are not directly comparable. The ISAT analysed all randomized patients by intention-to-treat, including some who did not undergo a repair, and obtained the primary outcome for 99% of participants. The National Study only analysed participants who underwent clipping or coiling, according to the method of repair, and obtained the primary outcome for 91% of participants. Time to repair was also considered differently in the two studies. The comparison between coiling and clipping was susceptible to confounding in the National Study, but not in the ISAT. The two study populations differed to some extent, but inspection of these differences does not support the view that coiling was applied inappropriately in the National Study. Therefore, there are many reasons why the two studies estimated different sizes of effect. The possibility that there were real, systematic differences in practice between the ISAT and the National Study cannot be ruled out, but such explanations must be seen in the context of other explanations relating to chance, differences in design or analysis, or confounding.

    Alagille syndrome is a rare autosomal dominant condition characterised by mutation in Jagged1 gene. Intracranial aneurysms may be seen in this condition and may present as subarachnoid hemorrhage. We describe the first case of superior cerebellar aneurysm rupture causing WFNS grade 1 subarachnoid haemorrhage in a 17-year-old girl. The clinical condition and management of this rare occurrence is discussed with a review of literature.

    To ascertain the number of cases of spontaneous (aneurysmal) subarachnoid haemorrhage presenting to Tan Tock Seng Hospital, Singapore, over a one year period, the demographics of the patients involved, their treatment and their eventual outcome. A retrospective study from June 1995 to June 1996. There were 62 patients admitted over this period with an average of 5 patients per month. Their ages ranged from 9 to 85 years with a mean of 54 years. All 62 patients underwent 4-vessel cerebral angiograms. Forty-three patients (69%) underwent clipping of their aneurysms. Twelve patients (19%) had negative angiograms. Four patients (6%) underwent coiling of their aneurysms via interventional neuroradiology techniques. Patients with subarachnoid haemorrhage of Grades 1 to 3 on the WFNS (World Federation of Neurological Surgeons) grading had a favourable outcome (Glasgow Outcome Score of 4 and 5) in 85% of the cases. The overall mortality rate for the operated group (all grades) was 11%. However for the group with good WFNS grading, namely the Grade 1 to 2 groups, there were no deaths. Twenty-four percent of patients developed clinically symptomatic vasospasm. Eighteen percent of patients required ventriculo-peritoneal shunting for hydrocephalus secondary to the subarachnoid haemorrhage. The overall management mortality (operated and non-operated cases) was 14% for proven aneurysmal and angiographically-negative spontaneous subarachnoid haemorrhage. These results are comparable to that of other reputable centers reported in the literature.

    A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible posterior communicating artery aneurysm, but revealed an unsuspected pituitary mass. Pituitary adenoma with pituitary apoplexy was diagnosed. Pituitary apopolexy is a syndrome comprising sudden headache, meningism, visual and/or oculomotor deficits, with an intrasellar mass. It is commonly due to haemorrhage or infarction within a pituitary adenoma. Treatment includes prompt steroid administration, and potentially surgical decompression. While subarachnoid haemorrhage is an important, well-recognised cause of sudden severe headache, other aetiologies, including pituitary apoplexy, should be considered and sought.

    AIM: To examine the efficacy and safety of nimodipine as an alternative to papaverine for the treatment of cerebral vasospasm following subarachnoid haemorrhage. METHODS: We retrospectively reviewed the procedure reports, anaesthetic records, clinical charts and CT and angiographic images of 9 patients who had received intra-arterial nimodipine; 1 of these patients received both nimodipine and papaverine. The difference in arterial luminal diameter before and after treatment was calculated as a percentage change. RESULTS: The average dose of nimodipine administered per vessel was 3.3 mg. The mean increase in arterial diameter was 66.6% in the vasospastic segment. There was no significant change in blood pressure of any of the subjects during endovascular treatment of vasospasm. CONCLUSION: Intra-arterial nimodipine is effective in improving angiographic vasospasm complicating subarachnoid haemorrhage. Further studies aimed at examining the clinical benefits of nimodipine are warranted, particularly in view of the low risk of adverse side effects of nimopidine when compared with papaverine.

    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.

    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.

    CT-angiography gains an increasing role in the initial diagnosis of patients with nontraumatic subarachnoid hemorrhage (SAH). However, the implementation of CT-angiography does not always exclude the necessity of conventional angiography. Our objective was to determine the practical utility and cost-effectiveness of CT-angiography. All patients with nontraumatic subarachnoid hemorrhage admitted to our university hospital after implementation of CT-angiography between June 1, 2011 and June 30, 2012 were retrospectively analyzed in regard to factors of treatment flow, radiation exposure, harms of contrast medium loading, and diagnostic costs. A control group of the same size was assembled from previously admitted SAH patients, who did not undergo pretreatment CT-angiography. Furthermore, cost-effectiveness analysis was performed. The final analysis consisted of 93 patients in each group. Of 93 patients with pretreatment CT-angiography, 74 had to undergo conventional angiography for diagnostic and/or therapeutic purposes. CT-angiography had significant impact on the reduction of collective effective radiation dose by 4.419 mSv per person (p = 0.0002) and was not associated with additional harms. Despite the significantly earlier detection of aneurysms with CT-angiography (p < 0.0001), there were no significant differences in the timing of aneurysm repair and duration of ICU and general hospital stay. There was an increase of diagnostic costs - the cost-effectiveness analysis showed, however, that benefits of CT-angiography in respect to radiation exposure and risk of conventional angiography-related complications justify the additional costs of CT-angiography. Although the implementation of CT-angiography in SAH diagnosis cannot completely replace conventional angiography, it can be approved in regard to radiation hygiene and cost-effectiveness. (orig.)

    Limited epidemiological data exist on subarachnoid haemorrhage (SAH) in China. Effective prevention requires knowledge of the rates and risk factors for SAH the most lethal type of stroke that most often affects younger adults. We report the methods and the initial experience of a new study to address this deficiency. To determine the incidence, risk factors, management and outcomes of SAH. The CHina Epidemiology Research In Subarachnoid Haemorrhage (CHERISH) is a prospective, population-based, case-control study in a defined region (study population 1.7 million) of the city of Baotou in Inner Mongolia, China. Cases of spontaneous SAH are identified using standard definitions through prospective surveillance of all major acute care hospitals with neurology/neurosurgery facilities, small hospitals/clinics, and the single city crematorium over a 2-year period. Verbal autopsy procedures are used to ascertain the probable causes of deaths outside of hospital. For each case, two nonrelative controls without SAH are matched by age (5-year strata), gender, and district of residence. Data are collected on socio-demography, lifestyle factors, and medical history, and blood is taken for the extraction and storage of DNA. Details of the clinical features, presentation, and management of SAH are obtained from cases, and survivors provide details on health care utilisation, physical function, health-related quality of life, and complications, at 6-months. The primary outcomes are overall, age- and gender-specific incidence, relative (odds ratios) and population-attributable risks for defined exposures, and 28-day and 6-month case fatality ratios and other outcomes. Preliminary experience confirms the completeness of the surveillance methods, with no clear missed out-of-hospital cases of SAH with sudden death, and of high participation and reliable data collection procedures. CHERISH is well placed to provide reliable estimates of the burden of SAH in China. © 2010 The Authors

    Recommended investigational care (RIC) of emergency department (ED) patients with suspected subarachnoid haemorrhage comprises lumbar puncture (LP) to detect xanthochromia if the preceding CT scan is negative. Retrospective audit of the investigational care of 100 consecutive ED patients presenting with possible subarachnoid haemorrhage. Of the 100 patients, 91 had negative CT, and 36 (39.6%) of these patients had an LP performed to detect xanthochromia (i.e. RIC). Fifty-five of 91 (60.4%) patients did not receive RIC. Of the 55 patients who did not receive RIC, 25 (45.5%) had a documented senior clinical decision not to perform an LP; 15 (27.3%) had no documented reason; five (9.1%) refused consent; two (3.6%) had an LP but no xanthochromia requested, one patient did not have an LP because of technical issues, six patients underwent CT angiography (CTA), and one patient underwent magnetic resonance angiography (MRA), in the absence of a LP, following a negative CT. Two patients underwent CTA following a negative xanthochromia result. Patients admitted to the emergency extended care unit had 6.85 times the odds of receiving RIC (95% CI 2.20-21.4). Fifty-five (55) of 91 (60%) ED patients did not receive RIC. Fifteen of the 55 did not have any documented justification for not performing an LP with xanthochromia testing. Admission to an emergency extended care unit was a predictor of receiving RIC. Inappropriate use of CTA and MRA was identified. These findings have important implications for patient safety. Multifaceted strategies are required to close this evidence-practice gap.

    To evaluate and predict factors influencing prognosis and/or clinical outcome at 6 months in patients with spontaneous subarachnoid haemorrhage, World Federation of Neurosurgical Societies (WFNS) grades iv and v. This was a retrospective study of a consecutive series of 394 patients admitted to our hospital with clinical and radiological diagnosis of spontaneous subarachnoid haemorrhage, from 1 January 1999 to 30 June 2009. We selected 121 patients who met the criteria of being in WFNS grades iv or v before treatment; 3 patients were excluded due to loss of tracking. The outcome variable was assessed 6 months after the event using the Glasgow Outcome Scale. A P value<.05 was considered statistically significant. One hundred and twenty-one patients were included in the statistical analysis. The average age of the patients in the series was 54 years (14-92). Patients who had a mean Glasgow Coma Scale lower than 7 points (P<.0001), those who were grade v (P<.0001) in the pre-treatment WFNS scale and those with pupillary disorder (P=.002) had a worse clinical outcome. Likewise, those with associated intraparenchymal hematoma (P=.020) and those not receiving any treatment (P=.020) were also associated with a poor clinical outcome. These results were statistically significant. Patients admitted with a WFNS grade v and/or presenting pupil disorder and/or intraparenchymal hematoma were associated with worse clinical outcomes.

    1994-01-01

    The predictive value of cranial computed tomography (CT) blood load and serial transcranial Doppler sonography for the development of delayed ischaemic neurological deficit was assessed in 121 patients following subarachnoid haemorrhage. Of the 121 patients, 81 (67 %) had thick layers of blood or haematoma, including intraventricular bleeding. The proportion of patients who developed delayed deficit was higher with increasing amounts of subarachnoid blood on the admission CT (51 % of 53 cases in Fisher grade 3; 35 % of 33 cases in grade 2; 28 % of 7 cases in grade 1, P < 0.01). Doppler velocities obtained from readings at least every 2 days following admission were higher in patients with delayed neurological deficit (peak velocity for grade 3 patients 176 ± 6 cm/s (mean ± SE), versus grade 2: 164 ± 7 cm/s; grade 4 149 ± 9, both P = 0.04, Mann-Whitney). Peak velocity and maximal 24-h rise tended to be higher within different CT grades in patients with a deficit than in those without; this difference was significant for grade 3 patients (P < 0.01). We conclude that a combined approach with CT and Doppler sonography provides greater predictive value for the development of delayed ischaemic neurological deficit than either test considered independently. The value of Doppler sonography may be greatest for patients with Fisher grade 3 blood, in whom the risk of delayed ischaemia is greatest. (orig.)

    The presence of blood in the subarachnoid space is an acute pathology with a serious risk of death and complications. The most common etiology (approximately 80%) is intracranial aneurysm. The aim of this study was to assess the role of bone subtracted computed tomographic angiography (BSCTA), a novel and noninvasive method for determining and characterizing intracranial aneurysms. Sixty consecutive patients with clinically suspected non-traumatic subarachnoid hemorrhage (SAH) were considered to enter the study. The subtraction quality was inadequate in ten patients; thus, they were excluded, leaving 50 patients (84.4%) in the study. Bone subtracted and non-subtracted 3D images were obtained from the BSCTA raw data sets. All images obtained by digital subtraction angiography (DSA), BSCTA, and computed tomographic angiography (CTA) were evaluated for the presence or absence of an aneurysm and the location, minimal sac diameter, and neck size ratio of the aneurysm. DSA was considered as the gold standard during the evaluation of the data. Of the 50 patients who participated in this study, 11 had no aneurysms as determined by both CTA and DSA. Examination of the remaining 39 patients revealed the presence of 51 aneurysms. While 3D-CTA could not detect six aneurysms that were located in the base of the skull, 3D-BSCTA easily detected them. Moreover, five aneurysms were only partially detected by 3D-CTA. According to this data, the sensitivity of 3D-BSCTA and 3D-CTA was calculated as 98% and 86.3%, respectively; the specificity was calculated as 100% and 90.9%, respectively, per aneurysm; and the sensitivity of 100% for 3D-BSCTA and 98% for 3D-CTA was achieved by using combined images with multi-planar reconstruction (MPR) and maximum intensity projection (MIP). BSCTA detected and characterized the aneurysms as well as DSA, and BSCTA and DSA gave concordant results in detecting aneurysms. BSCTA is easily accessible, less time consuming, and most importantly, a non

    In order to evaluate the sensitivity and specificity of magnetic resonance angiography (MRA) in spontaneous subarachnoid haemorrhage, 14 patients with recent haemorrhage verified by CT or lumbar puncture were investigated with both selective intra-arterial digital subtraction angiography (IA-DSA) and MRA by two independent teams, each having the same preangiographic information. The results were compared with each other and whenever possible (all positive cases except one) with those of surgical intervention. Seven patients were identified by MRA and IA-DSA as having a single aneurysm on the circle of Willis, 1 an aneurysm of the posterior inferior cerebellar artery 1 an aneurysm of the internal carotid artery (siphon) and 2 patients with two aneurysms on the circle of Willis. MRA and IA-DSA both failed to demonstrate aneurysms in 2 cases. Three patients had negative results on both methods and no surgical intervention was attempted. The aneurysms ranged from 0.3 to 1.5 cm in size. In most cases there was agreement between MRA and DSA, leading us to believe that, if the proper protocols are followed, MRA is a powerful alternative to other established methods in the detection of intracranial aneurysms. At this stage it will not replace IA-DSA prior to surgery, but the ability to obtain various projections using 3D MRA may improve surgical planning. (orig.)

    There is doubt as to whether acute haemorrhage is visible on MRI. We carried out MRI within 6 h of symptom onset on five patients with minor (low Hunt and Hess grades 1 or 2) subarachnoid haemorrhage (SAH) diagnosed by CT to search for any specific pattern. We used our standard stroke MRI protocol, including multiecho proton density (PD)- and T2-weighted images, echoplanar (EPI) diffusion- (DWI) and perfusion- (PWI) weighted imaging, and MRA. In all cases SAH was clearly visible on PD-weighted images with a short TE. In four patients it caused a low-signal rim on the T2*-weighted source images of PWI, and DWI revealed high signal in SAH. In the fifth patient SAH was perimesencephalic; susceptibility effects from the skull base made it impossible to detect SAH on EPI DWI and T2*-weighted images. Perfusion maps were normal in all cases. MRA and conventional angiography revealed an aneurysm in only one patient. Stroke MRI within 6 h of SAH thus shows a characteristic pattern. (orig.)

    Computed tomography (CT) is the 'gold standard' for detecting subarachnoid haemorrhage (SAH) and digital subtraction angiography (DSA) for visualising the vascular pathology. We studied retrospectively 180 patients with subarachnoid haemorrhage (SAH) who underwent first non-enhanced computed tomography (CT), then digital subtraction angiography (DSA) and finally operative aneurysm clipping. Our aim was to assess if the location of the ruptured aneurysm could be predicted on the basis of the quantity and distribution of haemorrhage on the initial CT scan. 180 patients with SAH were retrospectively studied. All the CT and DSA examinations were performed at the same hospital. CT was performed within 24 hours after the initial haemorrhage. DSA was performed alter the CT, within 48 hours after the initial haemorrhage. Two neuroradiologists, blind to the DSA results, analysed and scored independently the quantity and distribution of the haemorrhage and predicted the site of the ruptured aneurysm on the basis of the non-enhanced CT. DSA provided the location of the ruptured aneurysm. All the patients were operated upon, and the location of the ruptured aneurysm was determined. The overall reliability value (r,-value) between the two neuroradiologists for locating all ruptured aneurysms was 0.780. The corresponding value for the right MCA was 0.911, that for the left MCA 0.877 and that for the AcoA 0.736. Not all of the rc-values were calculated, either because the location of the rupture was constant or because the number of ruptures in the vessel was too small. Subarachnoid haemorrhage with a parenchymal hematoma is an excellent predictor of the site of the ruptured aneurysm with a statistical significance of p = 0.003. The quantity and pattern of the blood clot an CT within the day of onset of SAH is a reliable and quick cool for locating a ruptured MCA or AcoA aneurysm. It is not, however, reliable for locating other ruptured aneurysms. Subarachnoid haemorrhage with a

    This study evaluates care-related sociodemographic, clinical, and imaging factors and influences associated with outcome at discharge in patients with aneurismal subarachnoid haemorrhage. Retrospective cohort study in 334 patients treated at Hospital Hermanos Ameijeiras in Havana, Cuba between October 2005 and June 2014. Logistic regression analysis determined that the following factors were associated with higher risk of poor outcome: age older than 65 years (OR 3.51, 95% CI 1.79-5.7, P=.031), female sex (OR 2.17, 95% CI 1.22-3.84, P=.0067), systolic hypertension (OR 4.82, 95% CI 2.27-9.8, P=.0001), and hyperglycaemia at admission (OR 3.93, 95% CI 2.10-7.53, P=.0003). Certain complications were also associated with poor prognosis, including respiratory infection (OR 2.73, 95% CI 1.27-5.85, P=.0085), electrolyte disturbances (OR 3.33, 95% CI 1.33-8.28, P=.0073), hydrocephalus (OR 2.21, 95% CI 1.05-4.63, P=.0039), rebleeding (OR 16.50, 95% CI 8.24-41.24, P=.0000), symptomatic vasospasm (OR 19.00, 95% CI 8.86-41.24, P=.0000), cerebral ischaemia (OR 3.82, 95% CI 1.87-7.80, P=.000) and multiplex rebleeding (OR 6.69, 95% CI 1.35-36.39, P=.0019). Grades of iii and iv on the World Federation of Neurological Surgeons (OR 2.09, 95% CI 1.12-3.91, P=.0021) and Fisher scales (OR 5.18, 95% CI 2.65-10.29, P=.0008) were also related to poor outcome. Outcome of aneurysmal subarachnoid haemorrhage was related to age, sex, clinical status at admission to the stroke unit, imaging findings according to the Fisher scale, blood pressure, glycaemia and such complications as electrolyte disturbances, hydrocephalus, rebleeding, and multiplex rebleeding.

    We evaluated regional cerebral blood flow (rCBF) during vasospasm after subarachnoid haemorrhage ISAH) using automated voxel-based analysis of brain perfusion single-photon emission computed tomography (SPELT). Brain perfusion SPECT was performed 7 to 10 days after onset of SAH. Automated voxel-based analysis of SPECT used a Z-score map that was calculated by comparing the patients data with a control database. In cases where computed tomography (CT) scans detected an ischemic region due to vasospasm, automated voxel-based analysis of brain perfusion SPECT revealed dramatically reduced rCBF (Z-score ≤ -4). No patients with mildly or moderately diminished rCBF (Z-score > -3) progressed to cerebral infarction. Some patients with a Z-score < -4 did not progress to cerebral infarction after active treatment with a angioplasty. Three-dimensional images provided detailed anatomical information and helped us to distinguish surgical sequelae from vasospasm. In conclusion, automated voxel-based analysis of brain perfusion SPECT using a Z-score map is helpful in evaluating decreased rCBF due to vasospasm. (author)

    Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load. A series of consecutive patients with spontaneous SAH were divided into two groups: aneurysmal (aSAH) and non-aneurysmal--angiographically negative SAH (naSAH). Blood load was quantified so that the effect of aneurysmal origin could be resolved from the effect of the amount of blood spilled. Non-parametric regression was used to relate blood load to coma and poor outcome rates for aneurysmal bleeds. We analysed a total of 421 patients presenting during the period 2009-2011. Ninety aneurysmal cases presented with coma, seventy immediately in the early phase and seven shortly after rebleeding. None of the naSAH cases presented with immediate coma and 1 developed delayed coma. Delayed coma was associated with acute hydrocephalus in both groups. Aneurysmal origin was found to be an independent determinant of immediate coma (p=0.02) and poor outcome (pcoma and poor outcome in SAH are associated with an aneurysmal origin and do not characterize naSAH.

    Many aspects of the perioperative management of aneurysmal subarachnoid haemorrhage (SAH) remain controversial. It would be useful to assess differences in the treatment of SAH in Europe to identify areas for improvement. To determine the clinical practice of physicians treating SAH and to evaluate any discrepancy between practice and published evidence. An electronic survey. Physicians identified through each national society of neuroanaesthesiology and neurocritical care. A 31-item online questionnaire was distributed by the ENIG group. Questions were designed to investigate anaesthetic management of SAH and diagnostic and treatment approaches to cerebral vasospasm. The survey was available from early October to the end of November 2012. Completed surveys were received from 268 respondents, of whom 81% replied that aneurysm treatment was conducted early (within 24 h). Sixty-five percent of centres treated more than 60% of SAH by coiling, 19% had high-volume clipping (>60% of aneurysms clipped) and 16% used both methods equally. No clear threshold for arterial blood pressure target was identified during coiling, temporary clipping or in patients without vasospasm after the aneurysm had been secured. Almost all respondents used nimodipine (97%); 21% also used statins and 20% used magnesium for prevention of vasospasm. A quarter of respondents used intra-arterial vasodilators alone, 5% used cerebral angioplasty alone and 48% used both endovascular methods to treat symptomatic vasospasm. In high-volume clipping treatment centres, 58% of respondents used endovascular methods to manage vasospasm compared with 86% at high-volume coiling treatment centres (P practice patterns of European physicians involved in early treatment of SAH. Significant differences were noted among countries and between high and low-volume coiling centres.

    Full Text Available BackgroundThe authors are aware of only one article investigating amino acid concentrations in cerebrospinal fluid (CSF in patients with ruptured intracranial aneurysms, and this was published 31 years ago. Since then, both management of subarachnoid haemorrhage (SAH and amino acid assay techniques have seen radical alterations, yet the pathophysiology of SAH remains unclear.ObjectiveTo analyse the pattern of concentrations of amino acids and related compounds in patients with different outcomes following aneurysmal SAH.Methods49 CSF samples were collected from 23 patients on days 0–3, 5, and 10 post-SAH. Concentrations of 33 amino acids and related compounds were assayed by liquid chromatography tandem mass spectrometry in patients with good [Glasgow Outcome Scale (GOS 1–3] and poor (GOS 4–5 outcome.ResultsOf the 33 compounds assayed, only hydroxyproline and 3-aminoisobutyric acid appeared not to increase significantly following SAH. In poor outcome patients, we found significantly higher concentrations of aspartic acid (p = 0.038, glutamic acid (p = 0.038, and seven other compounds on days 0–3 post-SAH; glutamic acid (p = 0.041 on day 5 post-SAH, and 2-aminoadipic acid (p = 0.033 on day 10 post-SAH. The most significant correlation with GOS at 3 months was found for aminoadipic acid on day 10 post-SAH (cc = −0.81.ConclusionAneurysmal rupture leads to a generalised increase of amino acids and related compounds in CSF. The patterns differ between good and poor outcome cases. Increased excitatory amino acids are strongly indicative of poor outcome.

    Full Text Available Intracranial aneurysmal rupture is the common cause of spontaneous subarachnoid haemorrhage (SAH. This haemorrhage is typically diffuse and located in extracerebral subarachnoid space in which main cerebral arterial branches are situated. The intimate and long-term contact of arterial wall and blood products in the closed space causes the cerebral vasospasm as a serious and frequent complication of SAH. It is connected with significant morbidity and mortality due to developing of focal cerebral ischaemia and subsequently cerebral infarction. The aim of our experimental research was to create the animal model of vasospasm using the femoral artery due to examination of reduced basic dilator activity cause in arterial wall after SAH. The important characteristic of major cerebral arteries is their localization in the closed subarachnoid space which enables their to have long-term contact with blood products after haemorrhage. Thirty six femoral arteries (FA of eighteen female rats weighing about 300 g were used. In vivo, femoral arteries are microsurgically prepared in both inguinal regions in all rats. Eighteen arteries were encompassed by polytetrafluoroethylene (PTFE material forming closed tube and autologous blood was injected in the tube around the arterial wall. Additional eighteen arteries, as a control group, were also put in PTFE tube but without exposing to the blood. All rats are left to live for eight days. Afterwards, rats were sacrificed and their arteries were in vitro examined including an isometric tension measurement and histological changes analysis. The tension was measured during application of vasoconstrictors and vasodilatators (nitric oxide, NO. FA exposed to periadventitial blood exhibit hyper reactivity to constrictors (KCl, phenylephrine, acetylcholine compared to control group. It was also found that NO donor (sodium nitroprusside diminished arterial spasm induced by blood and vasoconstrictors. In conclusion, FA can be

    Magnesium treatment did not improve outcome in patients with aneurysmal subarachnoid haemorrhage in the Magnesium in Aneurysmal Subarachnoid Haemorrhage II trial. We hypothesized that high glucose levels may have offset a potential beneficial effect to prevent delayed cerebral ischemia. We investigated if magnesium treatment led to less delayed cerebral ischemia and if glucose levels interacted with magnesium treatment in the Magnesium in Aneurysmal Subarachnoid Haemorrhage II trial. To investigate the effect of magnesium treatment on occurrence of delayed cerebral ischemia and the interaction between glucose levels and magnesium treatment in subarachnoid hemorrhage patients. The Magnesium in Aneurysmal Subarachnoid Haemorrhage was a phase III randomized placebo-controlled trial assessing the effect of magnesium sulphate on clinical outcome in aneurysmal subarachnoid hemorrhage patients. For the current study, we included only the patients admitted to the University Medical Centre-Utrecht. We calculated hazard ratios for occurrence of delayed cerebral ischemia in patients treated with magnesium vs. placebo for the entire study population, and separately in the subgroups of patients with high and low mean fasting and mean daily glucose levels until onset of delayed cerebral ischemia. We used the cross-product of magnesium and glucose in the regression analysis to evaluate whether an interaction between magnesium and glucose existed. We included 616 patients: 307 received magnesium and 309 placebo; 156 patients had delayed cerebral ischemia. Hazard ratio for magnesium on occurrence of delayed cerebral ischemia was 1·0 (95% confidence interval: 0·7-1·4). Results were similar in patients with low or high fasting or daily glucose levels. We found no interactions between magnesium treatment and high fasting (P = 0·54) and daily glucose (P = 0·60). Magnesium treatment did not reduce the risk of delayed cerebral ischemia in patients with aneurysmal

    2012-11-01

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

    To evaluate the re-bleeding predictors in patients with delayed treatment of aneurysmal subarachnoid hemorrhage. A prospective cohort study enrolled 261 patients with aneurysmal subarachnoid hemorrhage, attending in Hermanos Ameijeiras Hospital from October 2005, and June 2014. An increased re-bleeding risk in the multivariate analysis was associated with grade III (OR 2.01; 95% CI; 1.06-3.84) and grade IV (OR 3.84; 95% CI; 2.06-7.31) on World Federation Neurological Surgeon (WFNS) scale; grade III (OR 2.04; 95% CI; 1.01-4.13) and grade IV (OR 2.12, 95% CI; 1.05-4.28) on the Fischer scale, aneurism location in posterior circulation (OR 2.45, 95% CI; 1.33-4.44), and anterior communicant artery (OR 1.57, 95% CI;1.00-2.46). Hypertension history was present in 60.9% (159 patients) and was also associated with risk of re-bleeding (OR 2.70, 95% CI; 1.00-7.30). Blood pressure, haematocrit, glycemic, aneurysm size, multiple aneurysms, and location in the middle cerebral artery, do not show any relationship. Hypertension history, poor grade (III and IV) on WFNS and Fisher scale and aneurysm location were independent risks factors of re-bleeding in patients with delayed aneurysmal treatment.

    Patients with suspected subarachnoid haemorrhage, a normal noncontrast computed tomography (CT) and cerebrospinal fluid (CSF) evidence of haemoglobin breakdown products often undergo CT angiography (CTA). If this is normal, then invasive catheter angiography may be offered. In current clinical practice, haemoglobin breakdown products are detected by spectrophotometry rather than visible xanthochromia, and CTA is performed on multidetector scanners. The aim of this study was to determine if such patients should still have a catheter angiography, given the associated risks. Patients positive for CSF spectrophotometry (n=26) were retrospectively identified from the clinical biochemistry information system and imaging data from the electronic radiology records were reviewed. Discharge letters were consulted to relate the biochemistry and radiology results to the final diagnosis. 15 patients with CT angiography were found. Nine patients had normal CT angiography. No causative aneurysms had been missed. One patient had small, coincidental aneurysms missed on initial reading of the CTA. The likelihood of a clinically significant aneurysm in a patient who is CT negative, lumbar puncture positive and CTA negative is low. Double reporting of negative CT angiograms may be advisable.

    Chronic hydrocephalus after aneurysmal subarachnoid haemorrhage (SAH) is easily diagnosed in most cases. However, the diagnosis is sometimes difficult in borderline cases, in which (a) pathognomonic clinical deterioration due to hydrocephalus is masked by the neurological deficits caused in the acute stage of SAH and (b) ventricular enlargement is not so marked on CT scan. The purpose of this study was to investigate whether or not iodine-123 labelled N-isopropyl-p-iodoamphetamine ( 123 I-IMP) single-photon emission tomography (SPET) is of value for the early diagnosis of borderline chronic hydrocephalus after SAH. Fifteen patients who met the criteria of borderline chronic hydrocephalus were selected for the study, and underwent a shunt operation. The patients were divided into a shunt-effective group and a shunt-ineffective group according to neurological improvement after the shunt operation. 123 I-IMP SPET was performed in the acute stage of SAH, within 1 week before the shunt operation, and 2 weeks after the shunt operation. Regional cerebral blood flow was estimated by the 123 I-IMP autoradiographic method. Pre-shunting periventricular low-perfusion areas showed statistically significant differences between the two groups (P 123 I-IMP SPET can be used for both the early diagnosis of borderline chronic hydrocephalus after SAH and the prediction of shunt effectiveness.

    Hypopituitarism following subarachnoid haemorrhage (SAH) has been reported to be a frequent occurrence. However, there is considerable heterogeneity between studies with differing patient populations and treatment modalities and most importantly employing differing endocrine protocols and (normal) reference ranges of GH. We aimed to examine prospectively a cohort of SAH survivors for development of hypopituitarism post-SAH using rigorous endocrine testing and compare GH response to glucagon stimulation with a cohort of healthy controls of a similar BMI. Sixty-four patients were investigated for evidence of hypopituitarism 3 months post-SAH with 50 patients tested again at 12 months. Glucagon stimulation testing (GST), with confirmation of deficiencies by GHRH/arginine testing for GH deficiency (GHD) and short synacthen testing for ACTH deficiency, was used. Basal testing of other hormonal axes was undertaken. Mean age of patients was 53±11.7 years and mean BMI was 27.5±5.7 kg/m(2). After confirmatory testing, the prevalence of hypopituitarism was 12% (GHD 10%, asymptomatic hypocortisolaemia 2%). There was no association between hypopituitarism and post-SAH vasospasm, presence of cerebral infarction, Fisher grade, or clinical grading at presentation. There was a significant correlation between BMI and peak GH to glucagon stimulation in both patients and controls. Identification of 'true' GHD after SAH requires confirmatory testing with an alternative stimulation test and application of BMI-specific cut-offs. Using such stringent criteria, we found a prevalence of hypopituitarism of 12% in our population.

    Although crystals are rarely identified on cerebrospinal fluid (CSF) microscopy, their presence can be of significant diagnostic value. We report a case of oxalate crystals seen on CSF microscopy of a 43-year-old woman. The patient presented with headaches, nausea and vomiting. CT of the head showed a small focus of hyper-density, suspicious of haemorrhage, in the right side of the pontine cistern. CSF cell count was within the normal range. Although no organisms were seen on microscopy, copious oxalate crystals were seen. The same crystals were seen on microscopy of CSF collected in a fluoride oxalate container used for glucose analysis. A follow-up contrast-enhanced CT angiogram did not demonstrate any abnormalities. It transpired that excess CSF had been collected into a fluoride oxalate container. This had subsequently been decanted into a plain container for microbiological analysis. Correct specimen collection should be emphasised when teaching lumbar puncture technique. PMID:26139652

    This study aimed to determine if performing cerebrospinal fluid spectrophotometry in addition to visual inspection detects more ruptured cerebral aneurysms than performing cerebrospinal fluid visual inspection alone in patients with a normal head CT scan but suspected of suffering an aneurysmal subarachnoid haemorrhage (SAH). We performed a single-centre retrospective study of patients presenting to the emergency department of a tertiary hospital who underwent both head CT scan and lumbar puncture to exclude SAH. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of an approach utilising both spectrophotometry and visual inspection (combined approach) was compared to visual inspection alone. A total of 409 patients (mean age 37.8 years, 56.2% female) were recruited and six (1.5%) had a cerebral aneurysm on angiography. The sensitivity of visual inspection was 50% (95% confidence interval [CI]: 12.4-82.6%), specificity was 99% (95% CI: 97.5-99.7%), PPV was 42.9% (95% CI: 10.4-81.3%) and NPV was 99.2% (95% CI: 97.8-99.8%). The combined approach had a sensitivity of 100% (95% CI: 54.1-100%), specificity of 79.7% (95% CI: 75.4-83.5%), PPV of 6.8% (95% CI: 2.6-14.3%) and a NPV of 100% (95% CI: 98.8-100%). The sensitivity of the combined approach was not significantly different to that of visual inspection alone (p=0.25). Visual inspection had a significantly higher specificity than the combined approach (p<0.01). The combined approach detected more cases of aneurysmal SAH than visual inspection alone, however the difference in sensitivity was not statistically significant. Visual xanthochromia should prompt angiography because of a superior specificity and PPV. Due to its reduced sensitivity, caution should be applied when using only visual inspection of the supernatant. Crown Copyright © 2014. Published by Elsevier Ltd. All rights reserved.

    We performed a blinded multireader study comparing MR angiography (MRA) with digital subtraction angiography (DSA) in 34 prospectively recruited patients who presented with acute subarachnoid haemorrhage (SAH). Two observers independently reviewed the MRA and DSA studies some months after clinical presentation. Presence of an aneurysm was rated on a 4-point confidence scale. Cases in which the initial interpretation of the observers varied were jointly reviewed to reach a consensus opinion. DSA was deliberately chosen not to represent the reference standard and the clinical course and surgical findings were used to explain significant differences between the consensus readings of MRA and DSA. Diagnostic confidence and interobserver agreement were, overall, higher on DSA than on MRA studies (κ DSA = 0.64 versus κ MRA = 0.52 with 95 % CI for Δ = κ DSA -κ MRA [-0.06, 0.31]). With both methods, discrepancies between observers were due to aneurysms overlooked rather than false-positive readings by one observer. Diagnostic accuracy therefore improved when the readings of the two observers were combined, particularly for MRA. Intermethod agreement was only fair and similar for both readers (κ reader 1 = 0.37 versus κ reader 2 = 0.32 with 95 % CI for Δ = κ reader 1 -κ reader 2 [-0.02, 0.11]). Both interobserver and intermethod agreements improved when the data were analysed on a per-study (positive or negative study) rather than on a per-aneurysm basis. Differences in the consensus reading were due to five aneurysms (four single and one multiple) detected only with MRA and five (two single and three multiple) detected only with DSA. MRA and DSA should be regarded as complementary in the investigation of patients with acute SAH. DSA can no longer be regarded as the reference standard. (orig.)

    Full Text Available Abstract Background To examine age and sex specific incidence and 30 day case fatality for subarachnoid haemorrhage (SAH in Scotland over a 20 year period. Methods A retrospective cohort study using routine hospital discharge data linked to death records. Results Between 1986 and 2005, 12,056 individuals experienced an incident SAH. Of these 10,113 (84% survived to reach hospital. Overall age-standardised incidence rates were greater in women than men and remained relatively stable over the study period. In 2005, incidence in women was 12.8 (95% CI 11.5 to 14.2 and in men 7.9 (95% CI 6.9 to 9.1. 30 day case fatality in individuals hospitalised with SAH declined substantially, falling from 30.0% in men and 33.9% in women in 1986-1990 to 24.5% in men and 29.1% in women in 2001-2005. For both men and women, the largest reductions were observed in those aged between 40 to 59 years. After adjustment for age, socio-economic status and co-morbidity, the odds of death at 30 days in 2005 compared to odds of death in 1986 was 0.64 (0.54 to 0.76, p Conclusions Incidence rates for SAH remained stable between 1986 and 2005 suggesting that a better understanding of SAH risk factors and their reduction is needed. 30 day case fatality rates have declined substantially, particularly in middle-age. However, they remain high and it is important to ensure that this is not due to under-diagnosis or under-treatment.

    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.

    Early brain injury/ischaemia (EBI) is a serious complication early after subarachnoid haemorrhage (SAH) that contributes to development of delayed cerebral ischaemia (DCI). This study aimed to determine the role of inotropic cardiac support using milrinone (MIL) on restoring acute cerebral hypoperfusion attributable to EBI and improving outcomes after experimental SAH. Forty-three male C57BL/6 mice were assigned to either sham surgery (SAH-sham), SAH induced by endovascular perforation plus postconditioning with 2% isoflurane (Control), or SAH plus isoflurane combined with MIL with and without hypoxia-inducible factor inhibitor (HIF-I) pretreatment. Cardiac output (CO) during intravenous MIL infusion (0.25-0.75 μg/kg/min) between 1.5 and 2.5 hours after SAH induction was monitored with Doppler echocardiography. Magnetic resonance imaging (MRI)-continuous arterial spin labelling was used for quantitative cerebral blood flow (CBF) measurements. Neurobehavioral function was assessed daily by neurological score and open field test. DCI was analyzed 3 days later by determining infarction on MRI. Mild reduction of cardiac output (CO) and global cerebral blood flow (CBF) depression were notable early after SAH. MIL increased CO in a dose-dependent manner (P<.001), which was accompanied by improved hypoperfusion, incidence of DCI and functional recovery than Control (P<.05). The neuroprotective effects afforded by MIL or Control were attenuated by hypoxia-inducible factor (HIF) inhibition (P<.05). These results suggest that MIL improves acute hypoperfusion by its inotropic effect, leading to neurobehavioral improvement in mice after severe SAH, in which HIF may be acting as a critical mediator. © 2017 John Wiley & Sons Australia, Ltd.

    Delayed cerebral ischemia (DCI) is an important contributor to poor outcome after aneurysmal subarachnoid haemorrhage (aSAH). Development of DCI is multifactorial, and inflammation, with or without infection, is one of the factors independently associated with development of DCI and poor outcome. We thus postulated that preventive antibiotics might be associated with a reduced risk of DCI and subsequent poor outcome in aSAH patients. We performed a retrospective cohort-study in intensive care units (ICU) of three university hospitals in The Netherlands. We included consecutive aSAH patients with minimal ICU stay of 72 h who received either preventive antibiotics (SDD: selective digestive tract decontamination including systemic cefotaxime or SOD: selective oropharyngeal decontamination) or no preventive antibiotics. DCI was defined as a new hypodensity on CT with no other explanation than DCI. Hazard ratio's (HR) for DCI and risk ratio's (RR) for 28-day case-fatality and poor outcome at 3 months were calculated, with adjustment (aHR/aRR) for clinical condition on admission, recurrent bleeding, aneurysm treatment modality and treatment site. Of 459 included patients, 274 received preventive antibiotics (SOD or SDD) and 185 did not. With preventive antibiotics, the aHR for DCI was 1.0 (95% CI 0.6-1.8), the aRR for 28-day case-fatality was 1.1 (95% CI 0.7-1.9) and the aRR for poor functional outcome 1.2 (95% CI 1.0-1.4). Preventive antibiotics were not associated with reduced risk of DCI or poor outcome in aSAH patients in the ICU.

    Full Text Available Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH, and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa is superior to the Mini-Mental State Examination (MMSE in screening for cognitive domain deficit in aSAH patients.We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2-4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score <-1.65 (below the fifth percentile. Cognitive impairment was defined as two or more cognitive domain deficits. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193.Both the MoCA and the MMSE were successful in differentiating between patients with and without cognitive domain deficits and cognitive impairment at both assessment periods. At 1 year post-ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009.Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases.

    The aim of this study was to evaluate the adherence to current guidelines for the investigation of suspected subarachnoid haemorrhage and the prevalence and outcome of computed tomography (CT)-negative aneurysmal subarachnoid haemorrhage. A retrospective review in a single large tertiary referral centre. A total of 796 patients, aged 16-90 years, who underwent lumbar puncture (LP) for suspected subarachnoid haemorrhage (SAH) following a negative or equivocal CT scan between January 2012 and November 2013 (23 months). Xanthochromia reports were obtained using the hospital's department of biochemistry database and clinical data for these patients were reviewed using patient notes. Of 796 CSF reports reviewed, 728 (91%) were negative for xanthochromia, 31 (4%) were positive and 37 (5%) were equivocal. Only 2 out of the 31 patients with positive spectrophotometry results were subsequently found to have an underlying aneurysm on CT angiography. A further 9 out of these 31 patients underwent digital subtraction angiography, with no cerebral aneurysms being detected. Amongst the 37 patients with equivocal xanthochromia reports, 13 underwent CT angiography and only 1 cerebral aneurysm was detected. In patients with clinically suspected SAH but who have negative or questionable CT findings, CSF analysis is likely to be negative in the vast majority of cases, which was 91% in our series. In patients yielding positive or equivocal CSF results the likelihood of an aneurysm being detected is low, amounting to three out of 68 or approximately one in 23 (approximately 4%). Overall in suspected SAH cases where CT scan has been negative, the rate for the detection of cerebral aneurysm is three out of 796 cases (0.4%).

    This study discusses the management of patients with the syndrome of inappropriate antidiuretic hormone secretion (SIADH), developed after subarachnoid hemorrhage, in a comparative manner in light of the literature. Without country or language restrictions, articles with high evidential value found in electronic databases were compared to our patients' data. After the literature review, three articles were included for systematic evaluation. Desmopressin was applied to the patients for the treatment of hyponatremia, volume contraction, and negative sodium balance caused by SIADH. However, it was not used for preventing re-bleeding. To prevent the development of this complication (SIADH), the use of desmopressin, an analogue of vasopressin, is important in routine clinical practice.

    Metal artefacts can impair accurate diagnosis of haemorrhage using flat detector CT (FD-CT), especially after aneurysm coiling. Within this work we evaluate a prototype metal artefact reduction algorithm by comparison of the artefact-reduced and the non-artefact-reduced FD-CT images to pre-treatment FD-CT and multi-slice CT images. Twenty-five patients with acute aneurysmal subarachnoid haemorrhage (SAH) were selected retrospectively. FD-CT and multi-slice CT before endovascular treatment as well as FD-CT data sets after treatment were available for all patients. The algorithm was applied to post-treatment FD-CT. The effect of the algorithm was evaluated utilizing the pre-post concordance of a modified Fisher score, a subjective image quality assessment, the range of the Hounsfield units within three ROIs, and the pre-post slice-wise Pearson correlation. The pre-post concordance of the modified Fisher score, the subjective image quality, and the pre-post correlation of the ranges of the Hounsfield units were significantly higher for artefact-reduced than for non-artefact-reduced images. Within the metal-affected slices, the pre-post slice-wise Pearson correlation coefficient was higher for artefact-reduced than for non-artefact-reduced images. The overall diagnostic quality of the artefact-reduced images was improved and reached the level of the pre-interventional FD-CT images. The metal-unaffected parts of the image were not modified.

    To correlate deficient pituitary function with life satisfaction and functional performance in subjects with a recent history of traumatic brain injury (TBI) and subarachnoid haemorrhage (SAH). Cross-sectional study. Eighteen subjects with TBI and 16 subjects with SAH underwent pituitary hormonal and functional assessments 5-12 months following the event. Adrenal reserve was assessed with a 1 mcg cosyntropin stimulation test and growth hormone deficiency (GHD) was diagnosed by insufficient GH response to GHRH-Arginine stimulation. Assessments of life satisfaction and performance-function included the Satisfaction with Life Scale (SWLS), Craig Handicap Assessment and Reporting Technique (CHART) and the Mayo Portland Adaptability Inventory-4 (MPAI-4). Hypopituitarism was present in 20 (58.8%) subjects, including 50% with adrenal insufficiency. Hypothyroidism correlated with worse performance on SWLS and CHART measures. GHD was associated with poorer performance on CHART and MPAI-4 scale. In this series of subjects with history of TBI and SAH, hypothyroidism and GHD were associated with diminished life satisfaction and performance-function on multiple assessments. Further studies are necessary to determine the appropriate testing of adrenal reserve in this population and to determine the benefit of pituitary hormone replacement therapy on function following brain injury.

    The aim of this study was to investigate and compare the levels of ionising radiation dose received by patients whilst undergoing radiological examination for Subarachnoid haemorrhage by conventional angiography (single and bi plane) and computed tomography angiography. The results obtained from previous examinations have been compared to consider which method of investigation delivers the lowest ionising radiation dose to the patient. Consideration was also given to comparing single plane angiography to bi plane angiography as empirical evidence suggested that radiologists received no formal training and only a small amount of informal training on newly installed equipment at the hospital in which the research was carried out. Would this lead to patients being inadvertently exposed to increased radiation as radiologists familiarised themselves with the equipment? The dose received by 30 patients examined for SAH by each modality was converted to effective dose (mSv) for comparison. These results were then further compared by removing the lowest and highest recorded doses to eliminate any bias that may have been caused by skewed data. The results showed that CTA consistently delivered a lower dose to patients than single or bi plane angiography and that bi plane delivered a lower mean average dose than single plane angiography, with or without any skewed data

    To examine age and sex specific incidence and 30 day case fatality for subarachnoid haemorrhage (SAH) in Scotland over a 20 year period. A retrospective cohort study using routine hospital discharge data linked to death records. Between 1986 and 2005, 12,056 individuals experienced an incident SAH. Of these 10,113 (84%) survived to reach hospital. Overall age-standardised incidence rates were greater in women than men and remained relatively stable over the study period. In 2005, incidence in women was 12.8 (95% CI 11.5 to 14.2) and in men 7.9 (95% CI 6.9 to 9.1). 30 day case fatality in individuals hospitalised with SAH declined substantially, falling from 30.0% in men and 33.9% in women in 1986-1990 to 24.5% in men and 29.1% in women in 2001-2005. For both men and women, the largest reductions were observed in those aged between 40 to 59 years. After adjustment for age, socio-economic status and co-morbidity, the odds of death at 30 days in 2005 compared to odds of death in 1986 was 0.64 (0.54 to 0.76), p p = 0.4 in those 70 years and above. Incidence rates for SAH remained stable between 1986 and 2005 suggesting that a better understanding of SAH risk factors and their reduction is needed. 30 day case fatality rates have declined substantially, particularly in middle-age. However, they remain high and it is important to ensure that this is not due to under-diagnosis or under-treatment.

    Patients without a subarachnoid haemorrhage (SAH) on brain CT scan (CT-negative), but a lumbar puncture (LP)-proven SAH, are a challenging patient category. The optimal diagnostic approach is still a matter of debate. Also, there is little knowledge on the probability of finding an underlying vascular lesion. In this observational study, a consecutive cohort of 94 patients with CT-negative, LP-positive SAH was prospectively collected between 1998 and 2013. The yield of diagnostic modalities as well as patient outcome was studied. In addition, risk factors for the presence of a vascular lesion were analysed. In 40 patients (43%), an intracranial vascular abnormality was detected: 37 aneurysms and three arterial dissections. Female gender was significantly associated with detection of a vascular lesion. Time between ictus and diagnosis of SAH was not associated with the presence of vascular pathology. Overall, 99% of patients had a modified Rankin Score of 0-2 after a median follow-up of 72 months. The yield of additional digital subtraction angiography in patients with a negative CT angiography was zero. In this study, the chance of finding a vascular lesion in a patient with CT-negative, LP-positive SAH was 43%, underlining the need for an adequate diagnostic workup. In general, the patient outcome was favourable. Female gender was found to be predictive for detecting a vascular lesion. In contrast with previous reports, the interval between ictus and LP was not associated with the presence of an aneurysm. Published by the BMJ Publishing Group Limited.

    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.)

    Cardiopulmonary abnormalities are common after aneurysmal subarachnoid haemorrhage (aSAH). However, the relationship between short- and long-term outcome is poorly understood. In this paper, we present how cardiac troponine elevations (cTnI) and pulmonary disorders are associated with short- and long-term outcomes assessed by the Glasgow Outcome Scale (GOS) and Extended Glasgow Outcome Scale (GOSE). A total of 104 patients diagnosed with aSAH were analysed in the study. The non-parametric U Mann-Whitney test was used to evaluate the difference between good (GOS IV-V, GOSE V-VIII) and poor (GOS I-III, GOSE I-IV) outcomes in relation to cTnI elevation and pulmonary disorders. Outcome was assessed at discharge from the hospital, and then followed up 6 and 12 months later. Pulmonary disorders were determined by the PaO 2 /FiO 2 ratio and radiography. The areas under the ROC curves (AUCs) were used to determine the predictive power of these factors. In the group with good short-term outcomes cTnI elevation on the second day after aSAH was significantly lower (p = .00007) than in patients with poor short-term outcomes. The same trend was observed after 6 months, although there were different results 12 months from the onset (p = .024 and n.s., respectively). A higher peak of cTnI was observed in the group with a pathological X-ray (p = .008) and pathological PaO 2 /FiO 2 ratio (p ≪ .001). cTnI was an accurate predictor of short-term outcomes (AUC = 0.741, p ≪ .001) and the outcome after 6 months (AUC = 0.688, p = .015). The results showed that cardiopulmonary abnormalities perform well as predictive factors for short- and long-term outcomes after aSAH.

    It is now well established that cognitive deficits are a frequent consequence of aneurysmal subarachnoid haemorrhage (SAH). The cognitive status in the acute phase of the illness may provide valuable prognostic information in relation to the effects of the proposed treatment and long-term functioning of the patient. A prerequisite for this task is the identification of instruments that might prove useful in the diagnosis of neuropsychological deficits in patients with SAH. For these purposes we used The Middlesex Elderly Assessment of Mental State (MEAMS) in order to assess the cognitive deficits consequent upon SAH. To assess the cognitive functioning of patients undergoing treatment for SAH of aneurysmal origin in the acute stage of the illness, using a modified form of the MEAMS. 49 patients participated in the study, none of whom had a previous history of neurological or psychiatric illness. The age of the patients ranged between 23-70 years. 35 (71%) patients received surgical treatment (clipping of the aneurysm neck) and in 14 (29%) the aneurysm was embolised. The patients were assessed on two occasions: the first on admission to the Neurosurgery department following the SAH, and on the second, following treatment to secure the aneurysm. A modified version of the MEAMS in two parallel versions was used in the assessment. The results obtained were evaluated with reference to a control group. A range of cognitive impairments was identified with the aid of the MEAMS in patients undergoing treatment for aneurysmal SAH. These included deficits in visual and auditory memory, executive, perceptual and visuo-spatial functions together with the tendency to perseverate. In those patients who underwent surgery, deficits were observed in the following areas: disorientation in relation to self, time and place; perceptual, memory and visuo-spatial impairments. The results obtained indicate that the Middlesex Elderly Assessment of Mental State, in the form used in the

    Purpose: The primary purpose of this project was to study the anatomical characteristics of intracerebral haematoma (ICH) in order to determine features that may negate the need for angiography in some patients. Material and Methods: The study was prospective and designed to investigate the underlying cause of non-traumatic ICH in 100 cases assessed by conventional angiography. Patients were excluded if there was a history of trauma or known pre-existing brain abnormality. All patients were examined with CT and angiography within 4 days of the ictus. Results: Ruptured aneurysms or arteriovenous malformations (AVMs) were diagnosed on the initial angiogram in 49% of cases: 27 AVMs and 22 aneurysms. One case of superior sagittal sinus thrombosis was also detected. Vascular abnormalities were found most frequently in the under-40 age group and in cases in which subarachnoid haemorrhage, intraventricular haemorrhage or extracerebral haematoma accompanied the ICH. The temporal lobe was the most frequent anatomical location (37%). When a temporal lobe haematoma extended into the Sylvian fissure from the inferior pole of the temporal lobe or when it was associated with subarachnoid haemorrhage, structural abnormalities were found in over 90% of cases. Conclusions: There are groups of patients with ICH in whom the CT features are highly suggestive of AVM or aneurysm rupture. If the initial angiography is negative in these cases, careful follow up by repeat angiography and/or MR imaging is essential. However, potentially treatable abnormalities cannot be excluded with certainty by the distribution of the haematoma on CT alone, even if there is a history of pre-existing hypertension. (orig.).

    Delayed cerebral ischemia (DCI) is a major complication after aneurysmal subarachnoid hemorrhage (SAH). One option to treat delayed cerebral ischemia is to use induced hypertension, but its efficacy on the eventual outcome has not been proven in a randomized clinical trial. This article describes the design of the HIMALAIA trial (Hypertension Induction in the Management of AneurysmaL subArachnoid haemorrhage with secondary IschaemiA), designed to assess the effectiveness of induced hypertension on neurological outcome in patients with DCI after SAH. To investigate whether induced hypertension improves the functional outcome in patients with delayed cerebral ischemia after SAH. The HIMALAIA trial is a multicenter, singe-blinded, randomized controlled trial in patients with DCI after a recent SAH. Eligible patients will be randomized to either induced hypertension (n = 120) or to no induced hypertension (n = 120). In selected centers, the efficacy of induced hypertension in augmenting cerebral blood flow will be measured by means of cerebral perfusion computerized tomography scanning. Follow-up assessments will be performed at 3 and 12 months after randomization by trial nurses who are blinded to the treatment allocation and management. We will include patients during five years. The primary outcome is the proportion of subarachnoid hemorrhage patients with delayed cerebral ischemia with poor outcome three-months after randomization, defined as a modified Rankin scale of more than 3. Secondary outcome measures are related to treatment failure, functional outcome, adverse events, and cerebral hemodynamics.

    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.

    Full Text Available Abstract Background There is still confusion and controversy over the diagnosis and optimal surgical treatment of non traumatic terminal ileal perforation-a cause of obscure peritonitis. Methods This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation. Results There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%, nonspecific inflammation(26%, obstruction(6%, tuberculosis(4% and radiation enteritis (1%. Simple closure of the perforation (49% and end to side ileotransverse anastomosis(42% were the mainstay of the surgical management. Conclusion Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

    Intraorbital meningoencephaloceles occur most commonly as a complication of traumatic orbital roof fractures. Nontraumatic congenital orbital meningoncephaloceles are very rare, with most secondary to destructive processes affecting the orbit and primary skull defects. Treatment for intraorbital meningoencephaloceles is surgical repair, involving the excision of herniated brain parenchyma and meninges and reconstruction of the osseous defect. Most congenital lesions present in infancy with obvious globe and orbital deformities; we report an orbital meningoencephalocele in a 3-year-old girl who presented with ptosis.

    1993-01-01

    The variable magnetic resonance imaging appearances of central nervous system haemorrhage, both intra- and extra-axial, are described. These will vary with the type of image contrast (T1 or T2 weighting), the nature of the imaging sequence (spin-echo or gradient-echo) and the time from onset of haemorrhage. Magnetic resonance imaging is a useful technique for imaging haemorrhage in the central nervous system as it yields temporal information about haematoma development, and it is the only non-invasive means of imaging intraspinal haemorrhage. However, in the imaging of haematomas within 24 h of onset and in subarachnoid haemorrhage computed tomography is the investigation of choice. 13 refs., 6 figs

    To investigate the diagnostic performance of postmortem multidetector computed tomography (PMMDCT) for the detection of fatal findings related to causes of non-traumatic death in the emergency department (ED). 494 consecutive cases of clinically diagnosed non-traumatic death in ED involving PMMDCT were enrolled. The fatal findings were detected on PMMDCT and classified as definite or possible findings. These findings were confirmed by autopsy in 20 cases. The fatal findings were detected in 188 subjects (38.1%) including 122 with definite (24.7%) and 66 with possible finding (13.4%). Definite findings included 21 cases of intracranial vascular lesions, 84 with intra-thoracic haemorrhage, 13 with retroperitoneal haemorrhage and one with oesophagogastric haemorrhage. In three patients who had initially been diagnosed with non-traumatic death, PMMDCT revealed fatal traumatic findings. Two definite findings (two haemopericardiums) and seven possible findings (two intestinal obstructions, one each of multiple liver tumours central pulmonary artery dilatation, pulmonary congestion, peritoneal haematoma, and brain oedema) were confirmed by autopsy. The causes of death were not determined in cases with possible findings without autopsy. PMMDCT is a feasible tool for detecting morphological fatal findings in non-traumatic death in ED. It is important to know the ability and limitation of PMMDCT. (orig.)

    In one year, cerebral angiograms were performed for intracranial haemorrhage (ICH) on 334 patients. No cause for haemorrhage could be identified in 41 (12 %), 30 of whom had predominantly subarachnoid (SAH) and 11 predominantly parenchymal haemorrhage (PH). These patients were prospectively examined by cranial MRI 1-6 weeks after the ictus. The MRI studies were positive in 7 patients (17 %). In the 30 patients examined after SAH, 2 studies were positive, showing an aneurysm in one case and a brain stem lesion of uncertain aetiology in the other. In those examined after PH, cavernous angiomas were shown in 2, a tumour in 1 and a vascular malformation in another; useful diagnostic information was thus obtained in 36 % of this group. (orig.)

    The case of a 57 y.o. male who has had severe headache of sudden onset without neck stiffness or other signs of neurological foci was reported. Initial CT scan showed perimesencephalic subarachnoid hemorrhage. Brain MRI and digital angiography were performed later and bleeding was interpreted as a result of an abnormal hemodynamic status developed by cerebral venous thrombosis. (author)

    Nontraumatic myositis ossificans circumscripta (MOC) is a rarely reported benign heterotopic ossification characterized by the aberrant formation of bone in extraskeletal soft tissues. Although a history of trauma can be elicited in 75% of MOC patients, the etiology is unclear in patients without inciting injury. MOC is associated with young male athletes, and is most often localized to the muscle groups of the extremities. Rare cases have been reported in children and adolescents of nontraumatic MOC in the neck. We present a 15-year-old adolescent with a rapidly growing, painful neck mass without traumatic stimulus.

    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 relationship between the extension and severity of subarachnoid hemorrhage, as demonstrated by computed tomography (CT), and hydrocephalus secondary to subarachnoid hemorrhage was studied. In 94 cases with subarachnoid hemorrhage, as analyzed by CT scan performed within 7 days after onset, high-density areas in the subarachnoid space were recognized in 61 cases (64%) and secondary hydrocephalus occurred in 22 cases (23%). 17 cases died within 2 weeks, before the occurrence of the hydrocephalus. The CT findings of subarachnoid hemorrhage was classified into 5 types, according to its severity and extension; especially the degree of high density in the basal cistern and/or cisterns around the brain stem was remarked. Secondary hydrocephalus after subarachnoid hemorrhage was observed in 90% of the cases; they had a density higher than a CT number of 60 in the basal cistern and/or cisterns around the brain stem (Type V). The mean interval between the onset of subarachnoid hemorrhage and the appearance of hydrocephalus was 20.6 days. We conclude that a significantly high density of extravasated blood in the subarachnoid space, especially in the basal cistern and/or the cisterns around the brain stem, can be predictive of secondary hydrocephalus after subarachnoid hemorrhage.

    In a group of 69 patients with pituitary tumours, 12 were found to have evidence of intratumoral haemorrhage on MRI, characterized by high signal intensity on short TR/TE sequences. This was verified in all but 1 patient. The majority of the bleedings occurred in macroadenomas. Five (42%) were prolactinomas and 4 (33%) were non-functioning adenomas. There were 2 GH- and 1 ACTH-secreting tumours. All 5 patients with prolactinomas were on bromocriptine medication. Two of the patients had a clinical picture of pituitary apoplexy. The haemorrhage was not large enough to prompt surgery in any of the patients. However, surgical verification of the diagnosis was obtained in 5 cases, while 6 patients were examined with follow-up MRI. (orig.)

    2012-01-01

    Ebola viruses are the causative agents of a severe form of viral haemorrhagic fever in man, designated Ebola haemorrhagic fever, and are endemic in regions of central Africa. The exception is the species Reston Ebola virus, which has not been associated with human disease and is found in the Philippines. Ebola virus constitutes an important local public health threat in Africa, with a worldwide effect through imported infections and through the fear of misuse for biological terrorism. Ebola virus is thought to also have a detrimental effect on the great ape population in Africa. Case-fatality rates of the African species in man are as high as 90%, with no prophylaxis or treatment available. Ebola virus infections are characterised by immune suppression and a systemic inflammatory response that causes impairment of the vascular, coagulation, and immune systems, leading to multiorgan failure and shock, and thus, in some ways, resembling septic shock.

    2004-04-01

    Full Text Available Haemorrhage is a rare but frequently fatal complication of pancreatic pseudocysts. The high mortality associated with pancreatic haemorrhage makes prompt and aggressive management essential. Occasionally, haemorrhage may present atypically, leading to delay in its diagnosis and management. This report details a case of pancreatic haemorrhage presenting as an upper gastrointestinal bleed and discusses the subsequent management. When managing patients with pancreatic pseudocysts who present with the stigmata of upper gastrointestinal bleeding, the possibility that the bleeding originates from the pancreas must always be borne in mind.

    In patients with non-aneurysmal subarachnoid hemorrhage (NA-SAH), the etiology is unknown and the bleeding source remains unidentified. However, the ABO blood type system has a profound role in patient's hemostasis and thrombosis. To date, the aspect of ABO blood type in incidence, clinical course, and outcome after NA-SAH has not been investigated. In this retrospective analysis, 81 patients with non-traumatic and non-aneurysmal subarachnoid hemorrhage treated between 2010 and 2014 at the author's institution were included. WFNS admission status, cerebral vasospasm, delayed infarction, ventriculoperitoneal shunt necessity, the Fisher grade, and the modified Rankin Scale were analyzed for their association with ABO blood type. Four hundred seventy patients with aneurysmal subarachnoid hemorrhage served as a control group. The AB blood type is more frequent in NA-SAH compared to aneurysmal patients and the German population (OR 2.45, p ≤ 0.05). Furthermore, NA-SAH with AB blood type showed a similar sequelae compared to aneurysmal patients in terms of shunt necessity (OR 2.00, p ≥ 0.05), cerebral vasospasm (OR 1.66, p ≥ 0.05), and delayed infarctions (OR 1.07, p ≥ 0.05). The clinical course of NA-SAH AB blood type patients shows similar severity as of aneurysmal subarachnoid hemorrhage. Therefore, patients with AB blood type should be under intensified observation.

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

    Hannon, M J

    2011-06-01

    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

    2015-01-01

    Aneurysmal subarachnoid hemorrhage (SAH) is a worldwide health burden with high fatality and permanent disability rates. The overall prognosis depends on the volume of the initial bleed, rebleeding, and degree of delayed cerebral ischemia (DCI). Cardiac manifestations and neurogenic pulmonary edema indicate the severity of SAH. The International Subarachnoid Aneurysm Trial (ISAT) reported a favorable neurological outcome with the endovascular coiling procedure compared with surgical clipping at the end of 1 year. The ISAT trial recruits were primarily neurologically good grade patients with smaller anterior circulation aneurysms, and therefore the results cannot be reliably extrapolated to larger aneurysms, posterior circulation aneurysms, patients presenting with complex aneurysm morphology, and poor neurological grades. The role of hypothermia is not proven to be neuroprotective according to a large randomized controlled trial, Intraoperative Hypothermia for Aneurysms Surgery Trial (IHAST II), which recruited patients with good neurological grades. Patients in this trial were subjected to slow cooling and inadequate cooling time and were rewarmed rapidly. This methodology would have reduced the beneficial effects of hypothermia. Adenosine is found to be beneficial for transient induced hypotension in 2 retrospective analyses, without increasing the risk for cardiac and neurological morbidity. The neurological benefit of pharmacological neuroprotection and neuromonitoring is not proven in patients undergoing clipping of aneurysms. DCI is an important cause of morbidity and mortality following SAH, and the pathophysiology is likely multifactorial and not yet understood. At present, oral nimodipine has an established role in the management of DCI, along with maintenance of euvolemia and induced hypertension. Following SAH, hypernatremia, although less common than hyponatremia, is a predictor of poor neurological outcome. PMID:25272066

    The spleen is one of the largest organ in the reticuloendothelial system and plays an important role in the activation of immune response. It is the organ most commonly injured after blunt abdominal trauma, and malignant lesions such as lymphoma, or these due to metastasis, occur not infrequently. Even so, it is ignored even in abdominal ultrasonography. Some benign splenic lesions, however can cause severe symptoms and result in high mortality, and their accurate diagnosis is therefore essential. This study describes the imaging findings and histopathologic features of various nontraumatic benign splenic lesions.

    Purpose: Spinal epidural hematoma (SEH) is a rare clinical entity with a bleak outcome. The aim of our study was to establish the value of MR findings in the diagnosis of nontraumatic SEH. Material and Methods: Seven patients with nontraumatic SEH were examined by MR at 1.5 T. Two patients were under anticoagulation therapy with heparin, and 2 others were taking salicylic acid. One patient had lupus erythematodes with a marked thrombocytopenia. One patient had a spinal arteriovenous malformation. Results: MR imaging permitted the accurate localization of extradural intraspinal expansive lesions which exhibited the characteristic signal intensities of blood. Five patients underwent laminectomy and evacuation of the hematoma. In the acute phase, the hematomas appeared isointense when compared with the spinal cord on T1-weighted images and hyperintense on T2-weighted images. Later the hematomas were hyperintense on T1-weighted images and showed signals identical to those of cerebrospinal fluid (CSF) on T2-weighted images. Conclusion: MR imaging established the exact diagnosis and localization of SEH in all cases. MR also can provide useful information about the age of the hematomas. (orig.)

    Loss of more than 500 mL of blood following childbirth is usually caused by failure of the uterus to contract fully after delivery of the placenta, and occurs in over 10% of deliveries, with a 1% mortality rate worldwide. Other causes of postpartum haemorrhage include retained placental tissue, lacerations to the genital tract, and coagulation disorders. Uterine atony is more likely in women who have had a general anaesthetic or oxytocin, an over-distended uterus, a prolonged or precipitous labour, or who are of high parity. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of non-drug interventions and of drug interventions to prevent primary postpartum haemorrhage? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 40 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: active management of the third stage of labour, carboprost injection, controlled cord traction, ergot compounds (ergometrine/methylergotamine), immediate breastfeeding, misoprostol (oral, rectal, sublingual, or vaginal), oxytocin, oxytocin plus ergometrine combinations, prostaglandin E2 compounds, and uterine massage.

    We report 36 cases of post-traumatic 'primary brain stem haemorrhage' visualized by the CT scan and confirmed at autopsy. Clinical experience shows that many technical factors influence the inability to visualize brain stem haemorrhages. Experimental injection of fresh blood into the pons and midbrain of cadavers shows that lesions as small as 0.25 ml in volume may be visualized. The volume and the anatomical configuration of traumatic lesions of the brain stem extended over a rostro-caudal direction, and their proximity to bony structures at the base of the skull are obstacles to the visualization of brain stem haemorrhages.

    Subarachnoid hemorrhage was produced in four Macaca nemestrina monkeys using the technique of Frazee. CT and MR imaging was performed immediately after the procedure and at frequent intervals up to 2 weeks after hemorrhage. The imaging studies were compared with clinical evaluations and pathologic specimens of all animals. Additional human clinical CT/MR studies of subarachnoid hemorrhage were also studied. Acute hemorrhage was recognized on MR images as an increase in signal in the region of clot compared with surrounding cerebrospinal fluid. This most likely reflects T1 shortening due to proton binding rather than a pure paramagnetic effect. While CT is sensitive to the hemoglobin protein in acute hemorrhage, the superior resolution of MR of the basal cisterns results in equal or better definition of acute subarachnoid hemorrhage on MR studies in many cases

    2013-01-01

    Full Text Available Subarachnoid hemorrhage (SAH is the bleeding into the subarachnoid space containing cerebrospinal fluid. The most common cause of SAH is trauma. Rupture of aneurysms, vascular anomalies, tumor bleeds and hypertension are other important etiologies. SAH in the setting of pituitary tumor can result from various causes. It can be due to intrinsic tumor related pathology, injury to surrounding the vessel during the operative procedure or due to an associated aneurysm. We discuss the pathological mechanisms and review relevant literature related to this interesting phenomenon. Early and accurate diagnosis of the cause of the SAH in pituitary tumors is important, as this influences the management.

    To assess the usefulness of computed tomography (CT) to identify subarachnoid bleeding in patients with neurologic deficits seeking emergency care for sudden headache within 6 hours of onset of symptoms. Retrospective observational study of patients presenting with sudden nontraumatic headache peaking during the previous hour in the absence of neurologic deficits. We ordered CT scans for all patients, and if the scan was normal we performed a lumbar puncture. All patients were then followed for 6 months. Eighty-five patients were included. Subarachnoid bleeding was identified in 10 (10.2%) patients by CT. Seventy- four lumbar punctures were performed in patients with negative CTs; the lumbar puncture was positive in 1 patient and inconclusive in 2 patients. In all 3 patients, bleeding was ruled out with later images; thus, no cases of subarachnoid hemorrhage were confirmed in the 74 patients who underwent lumbar puncture. Nor were any cases found in any of these patients during follow-up. A CT scan taken within 6 hours of onset of sudden headache is sufficient for confirming or ruling out subarachnoid bleeding in patients with sudden headache who have no neurologic deficits.

    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.

    1. In the present study we have studied the effects of deferoxamine treatment on lipid peroxidation and Na-K ATPase activity after experimental induction of subarachnoid haemorrhage (SAH) in guinea pigs. 2. We assessed the extent of lipid peroxidation by measuring the level of malondialdehyde and Na-K ATPase activity in 3 different groups (sham-operated, SAH, SAH + deferoxamine). 3. There was no significant difference in lipid peroxide content between sham-operated and haemorrhagic animals, but Na-K ATPase activity decreased after SAH. 4. Deferoxamine treatment reduced the malondialdehyde content and induced the recovery of Na-K ATPase activity, exerting a brain protective role against the detrimental effects of the haemorrhage.

    We studied MR fluid attenuated inversion recovery (FLAIR) pulse sequences in 37 cases with subarachnoid hemorrhage caused by aneurysmal rupture. FLAIR sequence suppressed the CSF signal and produced very heavy T{sub 2} weighted images. Subarachnoid hemorrhage was able to be demonstrated as high signal intensity on FLAIR sequences in all patients clear visualization of acute subarachnoid hemorrhage was able to be obtained by MR FLAIR sequences in not only Fisher`s group 3 or 4, but also Fisher`s group 2. Moreover it was suited for the detection of intraaxial hematoma, Sylvian hematoma, subdural hematoma and subarachnoid hemorrhage in the posterior fossa and interhemispheric fissure. Especially, it was useful for detecting intraventricular hemorrhage. Therefore, if patients suffering from subarachnoid hemorrhage present slight headache or atypical symptoms, sometimes it may be more suitable to perform MRI FLAIR pulse sequences first. Aneurysms were found in 21 cases (56.8%). When the aneurysmal size is more than 7 mm, the rate of detection becomes 100%. Aneurysms present various MR appearances because of flow characteristics. Aneurysms were demonstrated as low signal intensity except in 3 cases. In one out of 3 cases, aneurysms were revealed as high signal intensity and in the other two cases, it was revealed as mixed signal intensity. According to the previous studies, rapid flow was demonstrated as low signal intensity by vascular flow void, and delayed flow was demonstrated as high or mixed signal intensity by flow related enhancement and even echo rephasing. MR clearly delineates the size, the lumen, the flow, and the extraaxial location of aneurysms. (K.H.)

    The authors presented a patient with non-traumatic tension pneumocephalus 12 years after initial ventriculo-peritoneal shunt. A 60-year-old man had a past history of subarachnoid hemorrhage. At ÿtime, he underwent clipping surgery and emplacement of a ventriculoperitoneal shunt with a low pressure valve, and was discharged from hospital in a bedridden condition. After 12 years, he was transferred to our hospital because of dysarthria and right hemiparesis. On admission, he had multiple dimples of the scalp in the left frontal area where craniotomy had been carried out 12 years before. Head CT scan revealed air located mainly in bilateral subdural space and collapsed ventricles. We suspected that he had a tension pneumocephalus through a scalp-subdural fistula induced by long-term low intracranial pressure. Operation for closure of the fistula was intended. During the operation a subdural abscess was found so, artificial bone and the shunt system was removed. We were able to detect the fistula from the defect of the scalp to the subdural space and closed it by repairing a scalp defect, using dural plasty. Postoperative clinical course was uneventful and the patient was discharged. About 6 month after the operation, cranioplasty and lumbo-peritoneal shunt was performed. We must recognize that appropriate management of intracranial pressure after installation of a ventriculo-peritoneal shunt is necessary for prevention of tension pneumocephalus.

    Seven hundred and fifty five cases of acute non-traumatic subarachnoid hemorrhage (SAH) were admitted to the department of neurosurgery of our hospital from July, 1995 to March, 2004. In 555 patients cerebral angiography was conducted but initial angiography was negative in 30 patients. Except 10 general condition poor patients, in 20 initial angiogram-negative patients were undergone repeated angiography. The cause of SAH could not be demonstrated in 13 cases. The SAH in perimesencephalic and non-perimesencephalic cisturns was seen in 7 and 6 cases, respectively. Occipital and/or neck pain on admission was statistically more common among patients with perimesencephalic SAH than those with non-perimesencephalic SAH (p=0.029), and the prognosis of perimesencephalic SAH was good. We conclude that repeat angiography should not be recommended in patients with perimesencephalic SAH. Patients with non-perimesencephalic SAH had a higher rate of complication. In the non-perimesencephalic group, 3 patients developed hydrocephalus and 3 patients had vasospasm, which were found by repeated angiography. Therefore, repeated angiography is recommended for better clinical outcome by early detection and management of serious complications in this group of patients. (author)

    Exercise-associated amenorrhea is the cessation of menses in a woman following onset of training or an increase in training intensity. Its physiologic basis is characterized by consistently low levels of gonadotropin and ovarian hormones, but the underlying cause of this phenomenon is unknown. Although osteopenia has been described in amenorrheic women athletes, it has been primarily a laboratory diagnosis. Several recent studies have described a significantly lower bone mineral density (BMD) in the lumbar spine of amenorrheic athletes. Marcus et al. also reported an increased number of metatarsal and tibial stress fractures in a group of amenorrheic women. We report here the first case of a nontraumatic femur fracture in an amenorrheic athlete. A 32-yr-old white female, with four prior fibular stress fractures, suffered a left femoral shaft fracture during the 13th mile of a half-marathon. The fracture was successfully internally fixed. Biochemical studies showed no metabolic abnormality. Bone mineral density of the lumbar spine, femoral neck, tibia, and fibula were below the mean for both eumenorrheic and amenorrheic female athletes. Exercise-associated amenorrhea is a medical problem that may have serious implications for both competitive and high-intensity recreational female athletes.

    Non-traumatic convexal subarachnoid hemorrhage (CSAH) is a comparatively infrequent with various vascular and nonvascular causes, it rarely occurs concomitant to acute ischemic stroke. We report a case of a 59-year-old woman, visited emergency room with right side subjective weakness spontaneously. Magnetic resonance diffusion-weighted images revealed an acute infarction of anterior cerebral arterial territory. Computed tomographic angiography showed a left frontal CSAH without any vascular lesions. And other laboratory studies were non-specific. We treated with dual antiplatelet drugs (cilostazole [Otsuka Pharmaceutical Co., Ltd. tokyo, Japan] and Aspirin [Bayer Pharma AG., Leverkusen, Germany]). She has done well for a follow-up period. (5 months) This case demonstrates the CSAH with acute infarction is rare but need to work up to identify the etiology and antiplatelet dugs are taken into account for treatments.

    Computed Tomography has become increasingly important diagnostic method as the initial examination in the diagnosis of subarachnoid hemorrhage with direct detection of extravasated blood in basal cistern and cortical sulci. Furthermore, CT provides better and exact visualization of the presence, localization, extent and degree of intracerebral, intraventricular and subdural hemorrhage, infarction, hydrocephalus and rebleeding which may be associated with subarachnoid hemorrhage, and also could detect the causative lesions with contrast enhancement in many cases. The purpose of the paper is to describe the CT findings of subarachnoid hemorrhage due to various causes and to evaluate the diagnostic accuracy of CT in subarachnoid hemorrhage. Authors analysed a total of 153 cases with subarachnoid hemorrhage confirmed by lumbar puncture at Seoul National University Hospital from March 1979 to April 1981, with special emphasis on CT findings. All of the cases took CT scan and 125 cases of them angiography. The results are as follows: 1. Most prevalent age group was 4th to 6th decades (78%). The ratio of male to female was 1.1: 1. 2. Of 125 cases with angiography, aneurysm was a major cause (68%). Others were arterio-venous malformation (9.6%), Moya-moya disease (4%) and unknown (18.4%). 3. Of all 153 cases with CT scan, hemorrhage was demonstrated in 98 cases (64.1%); SAH in 72 cases (47.1%), ICH in 65 cases (42.5%), IVH in 34 cases (22.2%) and SDH in 1 case (0.7%). SAH combined with ICH was a major group (34.7%) in SAH. Detection rate of SAH was 68.3% within the first 7 days and 5.8% after 7 dyas. 4. In aneurysms, SAH was detected in 60 of 85 cases (70.6%); 88.1% within the first 7 dyas and 5.6% after 7 dyas. Anterior communicating artery was the most common site of the aneurysms (40%), in which detection rate of SAH was 100% within the first 7 days. SAH was combined with ICH in 38.3%. 5. On CT, SAH of unilateral Sylvian fissure was pathognomonic for ruptured MCA

    Traumatic subarachnoid-pleural fistulas are rare. The authors found nine cases reported since 1959. Seven have been secondary to trauma and two following thoracotomy. One patient's death is thought to be directly related to the fistula. The diagnosis should be suspected in patients with a pleural effusion and associated vertebral trauma. The diagnosis can usually be confirmed with contrast or radioisotopic myelography. Successful closure of the fistula will usually occur spontaneously with closed tube drainage and antibiotics; occasionally, thoracotomy is necessary to close the rent in the dura

    Full Text Available BACKGROUND Acute non-traumatic coma is one of the most common paediatric emergencies, which arouses much anxiety and apprehension in both parents and physicians. Due to heterogeneity of causes in these patients, prediction of outcome is difficult and unfortunately no single clinical, laboratory or electrophysiological parameters singly predict their outcome. Aetiology of nontraumatic coma varies depending on different geographical area. We have attempted to find the incidence, aetiology and outcome and delineate neurological signs to predict the prognosis in this study. The aim of this study is to study the incidence, aetiology and outcome of non-traumatic coma in children. MATERIALS AND METHODS 100 consecutive cases of non-traumatic coma between 5months and 15 years of age were selected for the study. Clinical signs and findings were recorded at admission (‘0’ Hr and after ‘48’ Hrs. of hospital stay. Aetiology of coma is determined on the basis of clinical history, examination and relevant laboratory investigations by the treating physician. These children were followed up till the death in the hospital or discharged from the hospital. Discharged patients were asked for followup after 4 weeks. During this period, all of them were evaluated by formal neurological examination and for special sensory involvement. The neurological outcomes were categorised into 6 groups (I-VI based on the severity of neurological involvement. Chisquare test was applied to determine the predictors of outcome. RESULTS 1. The incidence of non-traumatic coma in our hospital based study was 8.02% of all paediatric admissions and 21.64% of all PICU admissions. 2. CNS infections contributed the majority (58% of cases. (Dengue encephalitis-28%, viral encephalitis-12%, TB meningitis-8%, pyogenic meningitis- 6%, Shigella encephalopathy-3% and cerebral malaria-1%. 3. Other non-infectious aetiologies were toxic and metabolic group- 21%, post status epilepticus- 9

    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. (author)

    Aneurysmal subarachnoid hemorrhage (aSAH) incidence is not well studied. Varied definitions of "subarachnoid hemorrhage" have led to a lack of clarity regarding aSAH incidence. The impact of area-level socioeconomic disadvantage and geographical location on the incidence of aSAH also remains unclear. Using a population-based statewide study, we examined the incidence of aSAH in relation to socioeconomic disadvantage and geographical location. A retrospective cohort study of nontraumatic subarachnoid hemorrhages from 2010 to 2014 was undertaken. Researchers manually collected data from multiple overlapping sources including statewide administrative databases, individual digital medical records, and death registers. Age-standardized rates (ASRs) per 100,000 person years were calculated using the 2001 Australian population. Differences in incidence rate ratios were calculated by age, sex, area-level socioeconomic status, and geographical location using Poisson regression. The cohort of 237 cases (mean age, 61.0 years) with a female predominance of 166 (70.04%) included 159 confirmed aSAH, 52 community-based deaths, and 26 probable cases. The ASR for aSAH was 9.99 (95% confidence interval [CI], 8.69-11.29). A significant association between area-level socioeconomic disadvantage and incidence was observed, with the rate of aSAH in disadvantaged geographical areas being 1.40 times higher than that in advantaged areas (95% CI, 1.11-1.82; P = .012). This study uses a comprehensive search of multiple data sources to define a new baseline of aSAH within an Australian population. This study presents a higher incidence rate of aSAH with socioeconomic variations. As a key risk factor that may explain this paradox, addressing socioeconomic inequalities is important for effective prevention and management interventions.

    Objective: To study the etiology and the treatment of spontaneous non-aneurysmal subarachnoid hemorrhage. Methods: Twenty five cases of cerebral vessel angiography negative patients were analysed retrospectively, the majority of them had been undergone CT, DSA, MRI examination in order to define the etiological factor. Results: Among them, there was 1 case of spinal arteria-vena malformation, 1 case of hemorrhagic blood and 2 cases according to the revealing of MRI could be explained as bled vascular-occult malformation or cavernous angioma. Conclusion: The management and prognosis of patients in whom non-aneurysm is founded on the initial angiogram depends on the pattern of hemorrhage of the initial CT scanning, repeated angiography should be avoided for the case of premise encephalic non-aneurysmal SAH and MRI examination may be indicated to defining of etiological factors

  10. Management of aneurysmal subarachnoid hemorrhage.

    Spontaneous subarachnoid hemorrhage (SAH) affects people with a mean age of 55 years. Although there are about 9/100 000 cases per year worldwide, the young age and high morbidity and mortality lead to loss of many years of productive life. Intracranial aneurysms account for 85% of cases. Despite this, the majority of survivors of aneurysmal SAH have cognitive deficits, mood disorders, fatigue, inability to return to work, and executive dysfunction and are often unable to return to their premorbid level of functioning. The main proven interventions to improve outcome are aneurysm repair in a timely fashion by endovascular coiling rather than neurosurgical clipping when feasible and administration of nimodipine. Management also probably is optimized by neurologic intensive care units and multidisciplinary teams. Improved diagnosis, early aneurysm repair, administration of nimodipine, and advanced neurointensive care support may be responsible for improvement in survival from SAH in the last few decades. © 2017 Elsevier B.V.

  11. Troponin elevation in subarachnoid hemorrhage

    2015-03-01

    Full Text Available 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 >1 μg/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.

    We studied the clinical features and CT findings of 20 cases with fulminant subarachonid hemorrhages in the acute stage. They were admitted to our hospital within 3 hours after the attack as DOA (dead on arrival) or near DOA. CT-visualized subarachnoid hemorrhages were located in the basal cisterns surrounding the brain stem in all cases. In 90 % of the cases, the subarachnoid hemorrhage formed a clot or a thick layer. Massive intracerebral hematomas were observed in 10 % of the cases. Acute intraventricular hemorrhages were seen in 80 % of the cases. The mechanism of intraventricular hemorrhage in 70 % of the cases was of the reflux type, which was characterized by a reflux of the severe subarachnoid hemorrhage in the basal cistern. Acute and diffuse brain swelling on CT scan was observed in several cases, which also showed initial increased intracranial pressures. The major mechanisms leading to acute death or a very severe state soon after subarachnoid hemorrhage might be caused by acute brain-stem failure due to severe subarachnoid hemorrhages in the basal cisterns surrounding the brain-stem and an acute increase in intracranial pressure by cerebral edema following subarachnoid hemorrhage and secondary cerebral ischemia due to cardiac and respiratory arrest.

    To describe the magnetic resonance (MR) imaging findings of non-traumatic thickening of the anterior cruciate ligament (ACL) and to evaluate the associated lesions. Between January 2003 and August 2005, 44 knees of 44 patients who had thickened ACLs on MR images and had no history of knee trauma were analyzed retrospectively. The normal thickness of the ACL was measured on axial T2-weighted images of 40 healthy adult knees. The MR imaging findings of the thickened ACLs and associated lesions were analyzed. In 40 cases of healthy knees, the thickness of the proximal ACL was 3-6 mm. In 44 cases of non-traumatic thickening of the ACL, the thickness of the proximal ACL was 8-14 mm. There was an increased signal intensity and ill-defined border in all cases of thickened ACLs, linear low-signal intensity fibers parallel to the long axis of the thickened ACL (celery stalk appearance) in 24 cases, and entrapment in 10 cases. With respect to associated lesions, there was osteoarthritis in 40 cases, meniscal tears in 42 cases, and degeneration of the posterior cruciate ligament in 7 cases. Non-traumatic thickening of the ACL was associated with osteoarthritis and meniscal tears in almost all cases and showed increased signal intensity and ill-defined borders simulating acute ligamentous tears

    Objective: To determine the maternal health and fetal outcome in hepatitis C with obstetrical haemorrhagic emergencies. Study Design: An observational study. Place and Duration of Study: Department of Obstetrics and Gynaecology Unit-I, Liaquat University of Medical and Health Sciences Hospital, Hyderabad, Sindh, from January 2009 to December 2010. Methodology: All the women admitted during the study period with different obstetrical haemorrhagic emergencies were included. On virology screening, hepatitis C screening was done on all. The women with non-haemorrhagic obstetrical emergencies were excluded. Studied variables included demographic characteristics, the nature of obstetrical emergency, haemorrhagic conditions and maternal and fetal morbidity and mortality. The data was analyzed on SPSS version 20. Results: More frequent obstetrical haemorrhagic emergencies were observed with hepatitis C positive in comparison with hepatitis C negative cases including post-partum haemorrhage in 292 (80.88%) and ante-partum haemorrhage in 69 (19.11%) cases. Associated morbidities seen were disseminated intravascular coagulation in 43 (11.91%) and shock in 29 (8.03%) cases with hepatitis C positive. Fetal still birth rate was 37 (10.24%) in hepatitis C positive cases. Conclusion: Frequency of maternal morbidity and mortality and perinatal mortality was high in obstetrical haemorrhagic emergencies with hepatitis C positive cases. (author)

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

    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.

    Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

    Subarachnoid hemorrhage was produced in four Macaca nemestrina monkeys using the technique of Frazee. CT and MR imaging were performed immediately after the procedure and at frequent intervals up to 2 weeks after hemorrhage. The imaging studies were compared with clinical evaluations and pathologic specimens of all animals. Additional human clinical CT/MR studies of subarachnoid hemorrhage were also studied. Acute hemorrhage was recognized on MR as an increase in signal in the region of clot compared with surrounding cerebrospinal fluid. This most likely reflects T1 shortening due to proton binding rather than a pure paramagnetic effect. While CT is sensitive to the hemoglobin protein in acute hemorrhage, the superior resolution of the basal cisterns on MR images results in equal or better definition of acute subarachnoid hemorrhage on MR in many cases

    Full Text Available Post traumatic osteonecrosis of distal pole of scaphoid is very rare. We present a case of 34 years old male, drill operator by occupation with nontraumatic osteonecrosis of distal pole of the scaphoid. The patient was managed conservatively and was kept under regular follow-up every three months. The patient was also asked to change his profession. Two years later, the patient had no pain and had mild restriction of wrist movements (less than 15 degrees in either direction. The radiographs revealed normal density of the scaphoid suggesting revascularization.

    This thesis is comprised of three studies focusing on severe postpartum haemorrhage (PPH). PPH is a major cause of maternal morbidity and mortality worldwide. Risk factors include retained placenta, prolonged duration of the third stage of labour, previous caesarean section, and operative vaginal...... delivery. Occurrence and development of PPH are, however, unpredictable and can sometimes give rise to massive haemorrhage or even hysterectomy and maternal death. Severe haemorrhage can lead to coagulopathy causing further haemorrhage and requiring substitution with blood transfusions. The aim...... had a cardiac arrest, and a total of 128 women (52%) required a hysterectomy. Hysterectomy was associated with increased blood loss, increased number of blood transfusions, a higher fresh frozen plasma to red blood cell ratio (p=0.010), and an increased number of red blood cells before first platelet...

    Non-traumatic extradural spinal haematoma is an uncommon condition that is usually associated with a poor outcome. It may present acutely with signs and symptoms of major neurological dysfunction secondary to cord compression, or subacutely over a number of days or weeks with fluctuating symptoms. The exact aetiology of this condition is incompletely understood, but it is believed that the blood is venous in origin, as distinct from the arterial origin of intracranial extradural haematomas. Causes of non-traumatic extradural spinal haematoma include anticoagulation, vasculitis such as systemic lupus erythematosus (SLE), and spinal arteriovenous malformations. Conditions that may mimic an acute spinal haematoma include extradural abscess and extradural metastatic infiltration. It is important to make a diagnosis of extradural compression because surgery may offer the best hope in restoring neurological function in these patients. Imaging modalities used for the investigation of extradural haematomas include myelography, CT myelography (CTM) and MRI with or without gadolinium enhancement. The MR appearances of acute extradural abscess and extradural tumour can mimic an extradural haematoma. In subacute haematoma, owing to the magnetic properties of blood degradation products, MR is more specific in diagnosing and ageing of the haematoma.

  12. Usefulness of emergency ultrasound in nontraumatic cardiac arrest.

    Science.gov (United States)

    Volpicelli, Giovanni

    2011-02-01

    Treatment of nontraumatic cardiac arrest in the hospital setting depends on the recognition of heart rhythm and differential diagnosis of the underlying condition while maintaining a constant oxygenated blood flow by ventilation and chest compression. Diagnostic process relies only on patient's history, physical findings, and active electrocardiography. Ultrasound is not currently scheduled in the resuscitation guidelines. Nevertheless, the use of real-time ultrasonography during resuscitation has the potential to improve diagnostic accuracy and allows the physician a greater confidence in deciding aggressive life-saving therapeutic procedures. This article reviews the current opinions and literature about the use of emergency ultrasound during resuscitation of nontraumatic cardiac arrest. Cardiac and lung ultrasound have a great potential in identifying the reversible mechanical causes of pulseless electrical activity or asystole. Brief examination of the heart can even detect a real cardiac standstill regardless of electrical activity displayed on the monitor, which is a crucial prognostic indicator. Moreover, ultrasound can be useful to verify and monitor the tracheal tube placement. Limitation to the use of ultrasound is the need to minimize the no-flow intervals during mechanical cardiopulmonary resuscitation. However, real-time ultrasound can be successfully applied during brief pausing of chest compression and first pulse-check. Finally, lung sonographic examination targeted to the detection of signs of pulmonary congestion has the potential to allow hemodynamic noninvasive monitoring before and after mechanical cardiopulmonary maneuvers.

    Magnetic resonance imaging of subarachnoid hemorrhage (SAH) due to aneurysm rupture was evaluated in relation to CT findings in nine patients. Six patients were studied within 3 days and the other three patients were studied 4 to 6 days from the ictus of SAH using a 0.5 Tesla superconducting unit. In all of the patients, hematoma in the subarachnoid space and ventricles was demonstrated by the proton density-weighted spin echo sequence, which showed that bloody cerebrospinal fluid (CSF) had a higher signal intensity than brain tissue or normal CSF. Magnetic resonance imaging was more sensitive in detecting SAH and more informative as to the site of the ruptured aneurysm than CT. Despite some limitations in applying it to patients with acute SAH, magnetic resonace imaging has clear advantages in the diagnosis of SAH. (author)

  18. Intracranial drug delivery for subarachnoid hemorrhage.

    2012-01-01

    Tice and colleagues pioneered site-specific, sustained-release drug delivery to the brain almost 30 years ago. Currently there is one drug approved for use in this manner. Clinical trials in subarachnoid hemorrhage have led to approval of nimodipine for oral and intravenous use, but other drugs, such as clazosentan, hydroxymethylglutaryl CoA reductase inhibitors (statins) and magnesium, have not shown consistent clinical efficacy. We propose that intracranial delivery of drugs such as nimodipine, formulated in sustained-release preparations, are good candidates for improving outcome after subarachnoid hemorrhage because they can be administered to patients that are already undergoing surgery and who have a self-limited condition from which full recovery is possible.

    Moran, Byron; Bryan, Sean; Farrar, Ted; Salud, Chris; Visser, Gary; Decuba, Raymond; Renelus, Deborah; Buckley, Tyler; Dressing, Michael; Peterkin, Nicholas; Coris, Eric

    This article is a clinically relevant review of the existing medical literature relating to the assessment and diagnostic evaluation for athletes complaining of nontraumatic chest pain. The literature was searched using the following databases for the years 1975 forward: Cochrane Database of Systematic Reviews; CINAHL; PubMed (MEDLINE); and SportDiscus. The general search used the keywords chest pain and athletes. The search was revised to include subject headings and subheadings, including chest pain and prevalence and athletes. Cross-referencing published articles from the databases searched discovered additional articles. No dissertations, theses, or meeting proceedings were reviewed. The authors discuss the scope of this complex problem and the diagnostic dilemma chest pain in athletes can provide. Next, the authors delve into the vast differential and attempt to simplify this process for the sports medicine physician by dividing potential etiologies into cardiac and noncardiac conditions. Life-threatening causes of chest pain in athletes may be cardiac or noncardiac in origin, which highlights the need for the sports medicine physician to consider pathology in multiple organ systems simultaneously. This article emphasizes the importance of ruling out immediately life threatening diagnoses, while acknowledging the most common causes of noncardiac chest pain in young athletes are benign. The authors propose a practical algorithm the sports medicine physician can use as a guide for the assessment and diagnostic work-up of the athlete with chest pain designed to help the physician arrive at the correct diagnosis in a clinically efficient and cost-effective manner.

    To evaluate the usefulness of CT scanning in determining the etiology of spontaneous rupture of the kidney We retrospectively analyzed the CT findings of spontaneous rupture of the kidney in eleven patients, Four were male and seven were female, and they were aged between 20 and 71 (mean, 46.6) years. Both pre- and post-contrast enhanced CT scanning was performed in all patients. Spontaneous renal rupture was induced in seven cases by neoplasms (three angiomyolipomas, three renal cell carcinomas, and one metastatic choriocarcinoma), in three cases by infection or inflammation (acute and chronic pyelonephritis, and renal abscess), and in one, by renal cyst. Common CT findings of rupture of the kidney were the accumulation of high density fluid in the perirenal and anterior pararenal space, and inhomogeneous irregular low density of renal parenchyma and the rupture site. Angiomyolipoma showed fat and an angiomatous component in the lesion, while acute and chronic pyelonephrities revealed thinning of the renal parenchyma and an irregular renal outline. Renal cell carcinoma showed a dense soft tissue mass in the parenchyma. Well-defined, round low-density lesions were noted in the case of renal cyst and renal abscess. CT is very useful in diagnosing and determining the etiology of non-traumatic spontaneous rupture of the kidney and plays an important role in the evaluation of emergency cases

    Full Text Available The purpose of this study was to investigate using light microscopy the fibro-cellular components of arachnoid granulations affected by mild and severe subarachnoid hemorrage. The erythrocytes were in the channels delimitated by collagenous and elastic bundles and arachnoid cells, showing their tortuous and intercommunicating row from the pedicle to the fibrous capsule. The core portion of the pedicle and the center represented a principal route to the bulk outflow of cerebrospinal fluid and erythrocytes. In the severe hemorrhage, the fibrocellular components are desorganized, increasing the extracellular channels. We could see arachnoid granulations without erythrocytes, which cells showed big round nucleous suggesting their transformation into phagocytic cells.

    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.

    It has been hypothesised that paroxysmal coughing in infantile pertussis (whooping cough) could produce retinal haemorrhages identical to those seen in abusive head trauma. We aimed to test this hypothesis. This is a prospective study of infants hospitalised with pertussis in Auckland, New Zealand, from 2009 to 2014. The clinical severity of pertussis was categorised. All infants recruited had retinal examination through dilated pupils by the paediatric ophthalmology service using an indirect ophthalmoscope. Forty-eight infants with pertussis, aged 3 weeks to 7 months, were examined after a mean of 18 days of coughing. Thirty-nine had severe pertussis and nine had mild pertussis. All had paroxysmal cough, and all were still coughing at the time of examination. No retinal haemorrhages were seen. We found no evidence to support the hypothesis that pertussis may cause the pattern of retinal haemorrhages seen in abusive head trauma in infants. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    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.

    2016-01-01

    Nontraumatic emergencies of the head and neck represent a challenge in the field of neuroradiology for two reasons: first, they affect an area where the thorax joins the cranial cavity and can thus compromise both structures; second, they are uncommon, so they are not well known. Various publications focus on nontraumatic emergencies of the head and neck from the viewpoints of anatomic location or of particular diseases. However, these are not the most helpful viewpoints for dealing with patients in the emergency department, who present with particular signs and symptoms. We propose an analysis starting from the four most common clinical presentations of patients who come to the emergency department for nontraumatic head and neck emergencies: cervical swelling, dysphagia, dyspnea, and loss of vision.

    We assessed the usefulness of magnetic resonance angiography(MRA) and its techniques for differential diagnosis of hemorrhagic causes in patients with non-traumatic intracranial hemorrhagic diseases. We retrospectively reviewed 74 patients with non-traumatic intracranial hemorrhagic diseases, which were confirmed by radiological examinations(36 cases) and operations(38 cases). We compared the usefulness of magnetic resonance imaging(MRI) alone from MRI with MRA in evaluation of hemorrhagic causes. MRA was obtained by Time-of-Flight(TOF) and Phase Contrast(PC) technique. We investigated the usefulness of TOF and PC technique. MRI with MRA for detection of hemorrhagic causes(89%, 66 cases) was better than MRI only (64%, 47 cases). PC was better than TOF for evaluation of arteriovenous malformation and aneurysm due to subtraction of background noise(hemorrhage). MRI with MRA is more useful than MRI alone for evaluation of non-traumatic intracranial hemorrhagic causes

    Crimean-Congo haemorrhagic fever (CCHF) is a tickborne viral zoonosis with up to 50% mortality in humans caused by CCHF virus belonging to the genus Nairovirus, family Bunyaviridae. The geographical distribution of CCHF cases corresponds closely with the distribution of principle tick vectors...... that is species of Hyaloma. The disease presents with non-specific febrile symptoms, but progress to a serious haemorrhagic syndrome that, soon after, a full blown multi organ failure may develop with prominent features of liver damage and bleeding diathesis. The authors present a case of a 39-year-old man...

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

  17. Adult adrenal haemorrhage: an unrecognised complication of renal vein thrombosis

    There are many predisposing factors for neonatal adrenal haemorrhage but the causative factors are different in adults. Several cases of neonatal adrenal haemorrhage have been reported in association with renal vein thrombosis. This complication has not been documented in the adults. The presence of an adrenal mass in the setting of renal vein thrombosis should raise the possibility of adrenal haemorrhage even though this is extremely uncommon in adults.

    Fenestrations of the posterior communicating artery (PCoA) are extremely rare. Associated aneurysms have only been documented three times in the literature, and none associated with a subarachnoid hemorrhage. We describe a 52-year-old female who presented with a subarachnoid hemorrhage secondary to a ruptured saccular aneurysm at the proximal limb of a fenestrated right PCoA. The patient was also found to have bilateral middle cerebral artery (MCA) aneurysms. Surgical management included surmising the etiology of the subarachnoid hemorrhage with subsequent clipping of both the right PCoA and MCA aneurysm. The potential embryological mechanisms leading to a PCoA fenestration are discussed.

    The aim of this study was to analyze epidemiological and clinical data of patients with aneurysmal subarachnoid hemorrhage (SAH) in the Yaeyama islands, an isolated subtropical region of Japan. A total of 94 patients (31 men and 63 women, mean age 57.3 years) were diagnosed as having non-traumatic SAH during a 13-year period from 1989 to 2002. The age-and sex-adjusted annual incidence rate of SAH was 17.4 per 100,000 population. The incidence of SAH was the highest in August. Seventy-nine patients were hospitalized within 24 hours after onset of SAH. Seventeen patients were transferred by helicopter. The Hunt and Kosnik grade was I in 29 patients (30.9%). The CT Fisher group was 3 in 42 patients (44.7%). Ruptured aneurysm was detected in 78 patients (saccular type in 70 patients, small size in 49 patients, and internal carotid artery in 28 patients). Rebleeding occurred in 20 patients (21.3%). Symptomatic vasospasm occurred in 26 patients (27.7%). Acute and chronic hydrocephalus occurred in 25 (26.6%) and 22 (23.4%) patients respectively. A total of 120 neurosurgical operations were performed in 70 patients (operation for ruptured aneurysm in 62, early operation in 39). A total of 42 operative complications occurred in 29 patients. Fifty-one patients (54.3%) had a good outcome. The number of full-time neurosurgeons did not influence the performance of neurosurgical operation and outcome. In conclusion, epidemiologically, the high incidence of SAH in August is unusual. Patients with aneurysmal SAH in the Yaeyama islands have common clinical characteristics and undergo standard neurosurgical treatment. (author)

    Delayed cerebral ischemia (DCI) is a common, disabling complication of subarachnoid hemorrhage (SAH). Preventing DCI is a key focus of neurocritical care, but interventions carry risk and cannot be applied indiscriminately. Although retrospective studies have identified continuous electroencephalographic (cEEG) measures associated with DCI, no study has characterized the accuracy of cEEG with sufficient rigor to justify using it to triage patients to interventions or clinical trials. We therefore prospectively assessed the accuracy of cEEG for predicting DCI, following the Standards for Reporting Diagnostic Accuracy Studies. We prospectively performed cEEG in nontraumatic, high-grade SAH patients at a single institution. The index test consisted of clinical neurophysiologists prospectively reporting prespecified EEG alarms: (1) decreasing relative alpha variability, (2) decreasing alpha-delta ratio, (3) worsening focal slowing, or (4) late appearing epileptiform abnormalities. The diagnostic reference standard was DCI determined by blinded, adjudicated review. Primary outcome measures were sensitivity and specificity of cEEG for subsequent DCI, determined by multistate survival analysis, adjusted for baseline risk. One hundred three of 227 consecutive patients were eligible and underwent cEEG monitoring (7.7-day mean duration). EEG alarms occurred in 96.2% of patients with and 19.6% without subsequent DCI (1.9-day median latency, interquartile range = 0.9-4.1). Among alarm subtypes, late onset epileptiform abnormalities had the highest predictive value. Prespecified EEG findings predicted DCI among patients with low (91% sensitivity, 83% specificity) and high (95% sensitivity, 77% specificity) baseline risk. cEEG accurately predicts DCI following SAH and may help target therapies to patients at highest risk of secondary brain injury.

    Neuropeptide Y (NPY) is one of the most potent endogenous vasoconstrictors, and its contribution to the multifactorial cascade of cerebral vasospasm due to nontraumatic subarachnoid hemorrhage (SAH) is not yet fully understood. This experimental study compared the hemorrhage-specific course of NPY secretion into cerebrospinal fluid (CSF) and into plasma between 2 groups: patients with SAH and patients with basal ganglia hemorrhage (BGH) or cerebellar hemorrhage (CH) over the first 10 days after hemorrhage. Seventy-nine patients were prospectively included: SAH patients (n=66) (historic population) and intracerebral hemorrhage patients (n=13). All patients received an external ventricular drain within 24 hours of the onset of bleeding. CSF and plasma were drawn daily from day 1 to day 10. The levels of NPY were determined by means of competitive enzyme immunoassay. The CSF samples of 29 patients (historic population) who had undergone spinal anesthesia due to orthopedic surgery served as the control group. NPY levels in CSF were significantly higher in the 2 hemorrhage groups than in the control group. However, the 2 hemorrhage groups showed significant differences in NPY levels in CSF (SAH mean, 0.842 ng/mL vs. BGH/CH mean, 0.250 ng/mL; P<0.001) as well as in the course of NPY secretion into CSF over the 10-day period. NPY levels in plasma did not differ significantly among SAH, BGH/CH, and controls. Our findings support the hypothesis that excessive release of NPY into CSF but not into plasma is specific to aneurysmal SAH in the acute period of 10 days after hemorrhage. In BGH/CH, CSF levels of NPY were also increased, but the range was much lower.

    To compare the effectiveness of carbetocin with oxytocin with respect to maintain adequate uterine tone and to reduce the incidence and severity of postpartum haemorrhage. Moreover safety, adverse effects and the need of additional medications were evaluated. Prospective controlled clinical trial. We compared the effect of a single dose of carbetocin (n = 55) with oxytocin infusion (n = 55) in a women population undergoing to elective caesarean section with regional subarachnoid anaesthesia with at least one risk factor for postpartum haemorrhage. The mean ± SD of postoperative pain in the day of surgery in carbetocin group was significantly lower than in oxytocin group and remained significant till the third day after caesarean section. In the day of surgery and the first day after surgery, women of carbetocin group who needed analgesic drugs were significantly lower than women of oxytocin group. The differences of diuresis and of diuretic drugs need were not statistically significant between the two groups. A single carbetocin injection is efficacious and safe on the maintenance of uterine tone and on the limitation of blood losses, in peri- and in postoperative period. In addition, carbetocin was able to reduce pain perception during postoperative days improving quality life of women.

    Delayed ischemic neurological deficit (DIND) due to symptomatic vasospasm is a major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage (aSAH). The aim of this study was to elucidate the safety and feasibility of intrathecal milrinone infusion via lumber subarachnoid catheter for prevention of DIND after aSAH. We diagnosed 425 consecutive patients with aSAH who received clipping or coil embolization within 48 h after arrival. Patients with the evidence of vasospasm on CT angiography (CTA) received the milrinone therapy via lumbar subarachnoid catheter. DIND, delayed cerebral infarction (DCI), and modified Rankin scale at 3 months after SAH were used for the assessment of outcome. Of 425 patients, 170 patients (40.0 %) with CTA-proven vasospasm received the milrinone therapy. DIND was observed in 68 patients (16.0 %), DCI in 30 patients (7.1 %), and the overall mortality was 7.2 %. In patients with WFNS grade IV and V aSAH, 26 out of 145 patients (17.9 %) were presented with DIND, 12 (8.3 %) with DCI, and the mortality was 16.0 %. No major complication related to the milrinone injection was observed. Intrathecal milrinone injection via lumbar catheter was safe and feasible, and further randomized prospective studies are needed to confirm the effectiveness of this regimen in the patients with SAH.

    This article summarizes recent developments in the growing field of interventional neuroradiology for the treatment of acute cerebrovascular disease. We describe the possibilities in endovascular therapy of acute cerebral aneurysms using electrolytically detachable coils combined with trispan neck bridging devices and stent implantation to occlude acute wide neck aneurysms. Techniques and results of local intra-arterial thrombolytic therapy in acute stroke and central retinal artery occlusion are described and we discuss the potential for rapid, large-burden thrombus removal in cases of internal carotid artery thrombosis by rheolytic thrombectomy, percutaneous transluminal angioplasty and stent implantation. Emergency endovascular therapy using the transvenous approach to treat severe intracranial or intraocular hypertension and multifocal haemorrhagic venous infarction due to cerebral sinus thrombosis or dural fistulas is also described. In cases of acute bleeding of head and neck lesions following trauma, tumours after radiotherapy, arteriovenous malformations, epistaxis or from iatrogenic origin, angiography plays a major role in localizing the source of bleeding and occluding the damaged vessel during the same session using the same endovascular approach.

  6. Heparin: The Silver Bullet of Aneurysmal Subarachnoid Hemorrhage?

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Various neurological diseases have recently been associated with neuroinflammation and worsening outcomes. Subarachnoid hemorrhage has been shown to generate a potent neuroinflammatory response. Heparin is a potential effective anti-inflammatory agent to prevent initial injury as well as delayed neurological decline. Different mechanisms of action for heparin have been proposed including, but not limited to the binding and neutralization of oxyhemoglobin, decreased transcription and signal transduction of endothelin-1, inhibition of binding to vessel wall selectins and vascular leakage into the subarachnoid space as well as direct binding and neutralization of inflammatory molecules. With a reasonably safe side-effect profile, heparin has shown significant promise in small series in human studies of aneurysmal subarachnoid hemorrhage in decreasing both initial and delayed neurological injury. Further studies are needed to validate various neuroprotective features of heparin in subarachnoid hemorrhage as well as other disease states.

    2002-01-01

    Aim: Aneurysmal SAH is a devastating illness as two-thirds of the patients are disabled or die. Modern concepts of treatment include the prevention of the most serious complications after a surgical intervention (clipping, coiling) such as re-bleeding, vasospasms and stroke. The follow-up of cerebral perfusion could provide an objective basis for treatment. Material and Methods: In order to control the recently developed ''3H-therapy'' (hypertension-hypervolemia-hemodilution) we use the diagnostic possibilities of trans-cranial Doppler sonography (TCD), Tc-99m-HMPAO SPET (with semiquantitative parametric display) and angiography. Our algorithm includes a daily TCD, and, as a routine, the perfusion SPET on postoperative days 2/3, 8/10 and/or in case of a worsening of TCD results or neurological state. Results: In 20 consecutive cases 51 perfusion SPETs have been performed. Although, in general, a moderate 3H-therapy will be implemented postoperatively even without vasospasms or clinical signs the corrections of dosage highly depends on the TCD and SPET results. Vasospasms were the common reason for increased flow velocities measured by TCD and a (graduate) hypoperfusion on SPET (15 cases), but in three cases SPET showed a local or contra-lateral luxury perfusion indicative for stroke and, therefore, implicating a reduction/termination of the 3H-therapy. Conclusion: Our experiences with the new concept demonstrate not only a diagnostic performance of the used techniques but also an improved effectiveness of cost and benefit

  18. Lethal Ultra-Early Subarachnoid Hemorrhage Due to Rupture of De Novo Aneurysm 5 Months After Primary Aneurysmatic Subarachnoid Hemorrhage.

    2018-05-01

    Approximately 1% of all patients surviving rupture of a cerebral aneurysm suffer from a second aneurysmatic subarachnoid hemorrhage later in their lives, 61% of which are caused by rupture of a de novo aneurysm. Latency between bleedings is usually many years, and younger patients tend to achieve better outcomes from a second subarachnoid hemorrhage. We report an unusual case of lethal ultra-early rupture of a de novo aneurysm of the anterior communicating artery only 5 months after the initial subarachnoid hemorrhage and complete coiling in a young, healthy male patient. Despite complete aneurysm obliteration, young age, and good recovery, patients may be subjected to secondary subarachnoid hemorrhages from de novo aneurysms after only a few months of the initial bleeding. Early-control magnetic resonance angiography might hence be advisable. Copyright © 2018 Elsevier Inc. All rights reserved.

    To evaluate whether in patients with diffuse evaluation of a hemidiaphragm on chest radiographs, the apparence of the crura on CT might be helpful in differentiating between traumatic rupture of the diaphragm (TRD) and nontraumatic causes such as diaphragmatic palsy or diffuse diaphragmatic eventration. Among patients with diffuse elevations of a hemidiaphragm on chest radiograph, 27 who had patients undergone CT scans were retrospectively reviewed. Twelve patients had surgically proven TRD, and 15 had nontraumatic elevation of a hemidiaphragm such as diaphragmatic palsy or diffuse diaphragmatic eventration. Under the hypothesis that the affected crus is markedly thinner than the normal side in nontraumatic elevation but is normal in TRD ('crura sign', we optically assessed without measurement the thickness of both crura. In all patients with TRD, the thickness of the affected crus was similar to that of the contralateral side. In all patients with nontraumatic causes, however, the crus of the elevated hemidiaphragm was markedly thinner than that of the normal side. The 'crura sign' may be useful additional CT finding of traumatic rupture the diaphragm

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

    Late haemorrhagic disease of the newborn (HDN) can occur owing to a lack of vitamin K prophylaxis, as a manifestation of an underlying disorder or idiopatically from the 8th day to 12 weeks after birth. Eight infants admitted to Kocaeli University Hospital with nine episodes of late HDN between January 2002 and April 2005 were evaluated retrospectively from hospital records. The median age at presentation was 46 (26-111) days. All the infants were born at full-term to healthy mothers and were exclusively breast-fed. All had an uneventful perinatal history, except one who had meconium aspiration. Four patients had received no vitamin K prophylaxis and another three had uncertain histories. At presentation, six had intracranial bleeding and the remainder had bleeding either from the venepuncture site or the gastro-intestinal tract. The presenting signs and symptoms were irritability, vomiting, bulging or full fontanelle, convulsions and diminished or absent neonatal reflexes. Galactosaemia was detected in a 2-month-old infant with prolonged jaundice. There was no surgery-related mortality or complications but one survived for only 2 days on ventilatory support following surgery. Only one of the six survivors had severe neurological sequelae. Late HDN frequently presents with intracranial haemorrhage, leading to high morbidity and mortality. HDN can be the manifestation of an underlying metabolic disorder. Vitamin K prophylaxis of the newborn should be routine in developing countries.

    Magnetic resonance (MR) images of seven patients with olivary degeneration caused by cerebellar or brain stem haemorrhages were reviewed. In four patients with cerebellar haemorrhage, old haematomas were identified as being located in the dentate nucleus; the contralateral inferior olivary nuclei were hyperintense on proton-density- and T2-weighted images. In two patients with pontine haemorrhages, the old haematomas were in the tegmentum and the ipsilateral inferior olivary nuclei, which were hyperintense. In one case of midbrain haemorrhage, the inferior olivary nuclei were hyperintense bilaterally. The briefest interval from the ictus to MRI was 2 months. Hypertrophic olivary nuclei were observed only at least 4 months after the ictus. Olivary degeneration after cerebellar or brain stem haemorrhage should not be confused with ischaemic, neoplastic, or other primary pathological conditions of the medulla. (orig.)

    The early detection methods of nontraumatic osteo-necrosis of the femoral head were demonstrated with the dynamic or static enhancement MR imaging method using gadolinium-DTPA (Gd-DTPA). Even if with these methods we could not detect stage 0 of nontraumatic osteo-necrosis, but these pathological change should be induced at 0 stage in the patients who were medicated high-dose corticosteroids. The authors designed the big ROI (region of interest) dynamic MR imaging method to brake this diagnostic difficulty for 0 stage of femoral, and evaluated the efficacy of this technology with normal and femoral nontraumatic osteo-necrosis patients volunteer.

    This study was designed to examine the morphology of the spinal dural sac and contents, using magnetic resonance imaging in order to define the inner geometrical dimensions that confine the manoeuvre of an endoscope inserted in the lumbar region and along the thoracic and cervical spine. The morphology of the spine has been studied since the development of myelography. However, most studies have measured the diameters of the spinal cord only, not the size of the subarachnoid space. In addition, the few studies available on the subarachnoid space have focused on the cervical spine, leaving a near-complete dearth of data on the subarachnoid space dimensions along the thoracic spine. Based on MRI images of the spine from 42 patients, the dimensions of the spinal cord, dural sac, and subarachnoid space were measured at mid-vertebral and inter-vertebral disc levels. It was found that at each selected transverse level, the subarachnoid space tends to be symmetrical on the right and left sides of the cord, and measures 2.5 mm on average. However, the posterior and anterior segments, measured on the mid-sagittal plane, are generally asymmetrical and vary widely in size, ranging from 1 to 5 mm. These measurements match those found in previous studies, where these are available. The coefficient of variance for the dimensions of the subarachnoid space is as high as 42.4%, while that for the dimensions of the spinal cord is 10-15%. The findings presented here expand our knowledge of the spinal canal's morphology, and show that an endoscope designed to travel within the subarachnoid space must be smaller than 2.5 mm in diameter.

    Symptomatic intracerebral haemorrhage (sICH) remains the most feared complication of systemic thrombolysis in patients with ischaemic stroke. The aim of the study was to analyze the impact of different factors on the occurrence of sICH, depending on definition used. We retrospectively evaluated the influence of several factors on the occurrence of sICH (according to definitions used in ECASS2, SITS-MOST and NINDS studies) in 200 patients treated with systemic thrombolysis from 2006 to 2011. Multivariate analysis of impact of individual variables on the occurrence of haemorrhagic transformation (HT) and parenchymal haemorrhage type 2 (PH2) were performed. Haemorrhagic transformation occurred in 35 cases (17.5%). SICH was found in 10 cases according to ECASS2, in 7 cases according to SITS and in 13 cases according to NINDS. Older age was related to higher risk of sICH, regardless which definition was used (ECASS2: p = 0.014, SITS-MOST: p = 0.048, NINDS: p = 0.008), and female sex was related to higher risk of sICH according to NINDS and ECASS2 definition (p = 0.002 and p = 0.04, respectively). Blood glucose level and high NIHSS score (> 14 pts) were found as risk factor of sICH in ECASS2 definition (p = 0.044 and p = 0.03, respectively). In multivariate logistic regression higher NIHSS scores were associated with HT independent of age, gender and glucose level (p = 0.012). Multivariate analysis showed no impact of age, gender, severity of stroke and glucose level on presence of PH2. Definition of sICH can determine variables that are related to a high risk of this complication. In our study most factors correlated with sICH using the ECASS2 definition.

    Pathogenesis of viral haemorrhagic fever (VHF) is closely associated with alterations of the vascular system. Among the virus families causing VHF, filoviruses (Marburg and Ebola) are the most fatal, and will be focused on here. After entering the body, Ebola primarily targets monocytes/macrophages and dendritic cells. Infected dendritic cells are largely impaired in their activation potency, likely contributing to the immune suppression that occurs during filovirus infection. Monocytes/macrophages, however, immediately activate after viral contact and release reasonable amounts of cytokines that target the vascular system, particularly the endothelial cells. Some underlying molecular mechanisms such as alteration of the vascular endothelial cadherin/catenin complex, tyrosine phosphorylation, expression of cell adhesion molecules, tissue factor and the effect of soluble viral proteins released from infected cells to the blood stream will be discussed.

    The study investigated possible neurotoxic effects of increasing concentrations and doses of bupivacaine administered into the subarachnoid space in dogs. Fifty animals were allocated to five experimental groups: G1, control; G2, 5 mg 0.5 bupivacaine in 10% glucose solution; G3, 10 mg of 1% bupivacaine in 10% glucose solution; G4, 20 mg 2% bupivacaine in 10% glucose solution, and G5, 20 mg 2% bupivacaine in water. After 72 hours of observation, the animals were killed and the spinal cords removed for histologic examination by light microscopy. None of the animals showed any neurologic clinical disturbance following recovery from spinal anesthesia. One case of necrosis of nerve tissue was observed in G3 and four in G4. Increasing concentrations and doses of hyperbaric bupivacaine solutions increased the incidence of nerve tissue damage, which did not occur with hypobaric solutions. These results should contribute to the further understanding of neurologic complications following spinal anesthesia when large doses of local anesthetics in hyperbaric solutions are used.

    A non-ionic diagnostic medium, iohexol, was administered by subarachnoid injection to groups of six cynomolgus monkeys and compared with the vehicle, physiologically normal saline, and/or saline of equal osmolality to determine its potential for increasing total protein and leucocyte levels in cerebrospinal fluid. Also investigated was the effect of repeated spinal taps not subsequently followed by the intrathecal injection of test or control articles. In the monkey, unlike man, low-level leucocyte counts were consistently observed following initial withdrawal of spinal fluid. Elevated leucocyte and total protein levels were observed in the present investigations one day to a week after intrathecal injection of radiopaque, vehicle or saline solution. Total protein returned to normal levels earlier than did leucocyte counts. However, repeated needle puncture alone was found to be sufficient to cause an elevation of leucocytes 3 to 4 times the baseline level, while inflammatory effects were observed histologically only when autopsy was performed soon after the final spinal tap.

  13. Filoviral haemorrhagic fevers: A threat to Zambia?

    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.

    A 22-year-old female developed intracranial and spinal subarachnoid metastases 9 years after radiation therapy for a pineal germinoma. Computed tomographic scans showed no evidence of local recurrence. Cerebrospinal axis irradiation achieved total remission. Delayed subarachnoid dissemination may be caused by germinoma cells remaining dormant in the subarachnoid space, outside the radiation field. (author).

    Cervical laminectomy was performed in a 34-year old man with multiple spinal neurofibromas because of a slowly progressive medullary compression. Four weeks later a rapid deterioration necessitated iopamidol myelography by left lateral cervical puncture at C2 level. Despite the establishment of adequate spinal fluid contact, resulting in imaging of the subarachnoid space, part of the contrast medium entered the spinal cord, thus delineating a syrinx from the upper cervical extending to the upper thoracic level. After the puncture the patient developed triplegia, involving the left arm and both legs and a paresis of the right arm. He died from aspiration pneumonia. Autopsy revealed haemorrhagic necrosis of the spinal grey matter. This adverse effect of myelography is argued to have been conditioned by the extreme immobility and displacement of the spinal cord due to the presence of multiple neurofibromas. The deterioration four weeks after the operation was probably caused by a further compression of the spinal cord. (orig.)

    Full Text Available In the last decade, the desire for safer oral anticoagulants (OACs led to the emergence of newer drugs. Available clinical trials demonstrated a lower risk of OACs-associated life-threatening bleeding events, including intracranial hemorrhage, compared to warfarin. Nontraumatic spinal hematoma is an uncommon yet life-threatening neurosurgical emergency that can be associated with the use of these agents. Rivaroxaban, one of the newly approved OACs, is a direct factor Xa inhibitor. To the best of our knowledge, to date, only two published cases report the incidence of rivaroxaban-induced nontraumatic spinal subdural hematoma (SSDH. Our case is the third one described and the first one to involve the cervicothoracic spine.

    Lázaro Carreño, M I; Fraile Currius, R; García Clemente, A

    Non-traumatic limping is a common reason for consultation in paediatric emergencies. Although transient synovitis of the hip (TS) is the most frequent diagnosis, there are cases of limping secondary to serious pathologies. The aim of this review is to describe the variables related to non-traumatic limp that come to the paediatric emergency department to establish the best management protocol, making the most of resources and speeding up emergency care. A prospective study was conducted, selecting all children less than 15 years old who consulted aspaediatric emergencies for non-traumatic limping during the 2014. Clinical variables, complementary examinations and diagnoses were collected in the emergency room consultation and 6 months after the consultation RESULTS: During 2014, 146 patients (0.69% of the emergencies) were included in the non-traumatic limping study. Four cases of severe limping were diagnosed: 2 leukaemias, 1 septic arthritis and 1 acetabular bone tumour. The most frequent diagnosis was TS (53.16%). At 6 months, 135 children (92.4%) had resolved lameness. The diagnosis was changed in 9 children (6.1%). Children with TS had fewer days of evolution, and 77% were between 3 and 10 years old. Children with a final diagnosis of severe pathology had a limp for longer, fever and did not weight bear on ambulation. In limping of probable hip origin, at the ages of between 3 and 10, without fever or systemic symptoms and of less than one week's onset, it is possible to make a clinical diagnosis of TS limiting the use of complementary examinations.

    To describe national emergency department (ED) trends in computed tomography (CT) and ultrasound imaging for the evaluation of pediatric nontraumatic abdominal pain from 2007 through 2014. We used data from the National Hospital Ambulatory Medical Care Survey to measure trends in CT and ultrasound use among children with nontraumatic abdominal pain. We performed multivariable logistic regression to measure the strength of the association of ED type (pediatric versus general ED) with CT and ultrasound use adjusting for potential confounding variables. Of an estimated 21.1 million ED visits for nontraumatic abdominal pain, 14.6% (95% confidence interval [CI], 13.2%-16.0%) had CT imaging only, 10.9% (95% CI, 9.7%-12.1%) had ultrasound imaging only, and 1.9% (95% CI, 1.4%-2.4%) received both CT and ultrasound. The overall use of CT and ultrasound did not significantly change over the study period ( P trend .63 and .90, respectively). CT use was lower among children treated in pediatric EDs compared with general EDs (adjusted odds ratio 0.34; 95% CI, 0.17-0.69). Conversely, ultrasound use was higher among children treated in pediatric EDs compared with general EDs (adjusted odds ratio 2.14; 95% CI, 1.29-3.55). CT imaging for pediatric patients with nontraumatic abdominal pain has plateaued since 2007 after the steady increase seen in the preceding 9 years. Among this population, an increased likelihood of CT imaging was demonstrated in general EDs compared with pediatric EDs, in which there was a higher likelihood of ultrasound imaging. Dissemination of pediatric-focused radiology protocols to general EDs may help optimize radiation exposure in children. Copyright © 2017 by the American Academy of Pediatrics.

    2014-04-01

    Despite the progress made in the management of subarachnoid hemorrhage (SAH), many patients complain of persistent psychosocial and cognitive problems. The present study was performed to explore the significance of psychological traumatization by the bleeding with respect to psychosocial results after SAH. A series of 45 patients were examined in a cross-sectional study an average of 49.4 months after SAH by means of a quality-of-life questionnaire, the Beck Depression Inventory, the German version of the Impact of Event Scale (IES), and a clinical interview (Structured Clinical Interview for DSM Disorders) to make the diagnosis of chronic posttraumatic stress disorder (PTSD). Twenty-nine patients underwent surgery for treatment of a ruptured aneurysm; the remaining 16 patients had SAH of unknown origin. Twelve patients (27%) exhibited PTSD, and almost two-thirds of the 45 patients in the study reported substantial fear of recurrent hemorrhage. Not only the presence of PTSD but the severity of psychological traumatization as assessed by the IES explained up to 40% of the variance of the self- and proxy-rated impairments. Multivariate analyses revealed psychological traumatization (IES) and neurological state on admission (Hunt and Hess grade) as substantial predictors of the self- and proxy-rated quality of life, explaining 31% and 42% of the variance, respectively. Even several years after SAH, the severity of psychological traumatization by the bleeding substantially determines the degree of psychosocial impairment. In the future, this issue should be addressed in the care of these patients. Furthermore, the development of psychological interventions is called for to prevent the emergence of PTSD after SAH.

    Aneurysmal subarachnoid hemorrhage (aSAH) is a sudden debilitating condition affecting individuals during the most productive times of their lives. Treatment advances have reduced mortality rates but increased the number of survivors facing deficits in physical and neuropsychological function. This study examined associations between neuropsychological function and work productivity after aSAH. Fifty-two patients with aSAH, employed before hemorrhage, were recruited from an ongoing National Institutes of Health study. Work Limitations Questionnaire (WLQ), neuropsychological tests (executive function, psychomotor speed, attention and mental flexibility, memory), and Patient Assessment of Own Function were completed at 3 and 12 months after aSAH. Subjects in this analysis reported some level of difficulty in work productivity at 3 and 12 months (35% and 30%, respectively) after hemorrhage. Lower WLQ scores in time management and mental/interpersonal subscales were associated with poorer performance in psychomotor function (r = .5, p = .04 and r = .42, p = .09). Poorer mental flexibility and working memory correlated with time management difficulty at 3 months (r = -.4, p = .09 and r = .54, p = .02). Patients performing poorly on story recall tests were more likely to report difficulty with job physical performance (r = -.42, p = .09) and completing work effectively (r = .61, p = .009). Poorer working memory performance was associated with lower scores on mental/interpersonal WLQ subscales (r = .45, p = .05) and overall health-related work productivity loss (r = .47, p = .04). WLQ areas also correlated with participants' perception of their neuropsychological function after aSAH. These results suggest that neuropsychological deficits impact work quality after hemorrhage and provide strong impetus for future studies so that domain-specific interventions can be implemented to improve outcomes that affect quality of life including work productivity.

    Vasospasm and delayed cerebral ischemia remain to be the common causes of increased morbidity and mortality after aneurysmal subarachnoid hemorrhage. The majority of clinical vasospasm responds to hemodynamic augmentation and direct vascular intervention; however, a percentage of patients continue to have symptoms and neurological decline. Despite suboptimal evidence, clinicians have several options in treating refractory vasospasm in aneurysmal subarachnoid hemorrhage (aSAH), including cerebral blood flow enhancement, intra-arterial manipulations, and intra-arterial and intrathecal infusions. This review addresses standard treatments as well as emerging novel therapies aimed at improving cerebral perfusion and ameliorating the neurologic deterioration associated with vasospasm and delayed cerebral ischemia.

    Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by vascular dysplasia and haemorrhage. It is manifested by mucocutaneous telangiec-tases and arteriovenous malformations in organs such as lungs, liver and brain. We present a case of HHT. A 16-year-old patient with a history of recurrent epistaxis was admitted to the local hospital with chest pain and desaturation. A CT scan revealed pulmonary arteriovenous malformations.

    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.

    There are currently no guidelines in the UK for the specific management of hereditary haemorrhagic telangiectasia related epistaxis. The authors aimed to review the literature and provide an algorithm for the management of hereditary haemorrhagic telangiectasia related epistaxis. The Medline and Embase databases were interrogated on 15 November 2013 using the search items 'hereditary haemorrhagic telangiectasia' (title), 'epistaxis' (title) and 'treatment' (title and abstract), and limiting the search to articles published in English. A total of 46 publications were identified, comprising 1 systematic review, 2 randomised, controlled trials, 27 case series, 9 case reports, 4 questionnaire studies and 3 in vitro studies. There is a lack of high-level evidence for the use of many of the available treatments for the specific management of epistaxis in hereditary haemorrhagic telangiectasia. Current management should be based on a multidisciplinary team approach involving both a hereditary haemorrhagic telangiectasia physician and an ENT surgeon, especially when systemic therapy is being considered. The suggested treatment algorithm considers that the severity of epistaxis merits intervention at different levels of the treatment ladder. The patient should be assessed using a reproducible validated assessment tool, for example an epistaxis severity score, to guide treatment. More research is required, particularly in the investigation of topical agents targeting the development and fragility of telangiectasiae in hereditary haemorrhagic telangiectasia.

    To describe the population admitted in an emergency department of a teaching hospital for severe bleeding associated with direct oral anticoagulants (DOAC). During a three-year period (2012-2014) patients older than 16 years were prospectively identified by haemorrhagic symptoms from computerised requests. At least one of the following criteria defined major haemorrhage: haemorrhagic shock, unstable haemodynamic, need for transfusion or haemostatic procedure, or a life threatening location. Fifty four patients, 23 receiving dabigatran, 30 rivaroxaban and one apixaban were included, 2 in 2012, 35 in 2013 and 17 in 2014. Median age was 84 years (range 63-99) with a sex ratio of 1.16. Haemorrhagic complications were gastrointestinal (n=27), intracranial (n=12) or miscellaneous (n=15). Indication of DOAC was stroke prevention in atrial fibrillation in 49 cases and deep vein thrombosis in 5 cases. Hospitalization was required for 45 patients (83%) with a mean length of stay of 8.5 days. Sixteen patients needed intensive care. Reversal therapy was prescribed in 11 patients. At 1 month, overall mortality was 24%, reaching 41.7% for intracranial haemorrhage. Among surviving patients, DOAC was stopped in 10 cases, continued in 17 patients and switched for other antithrombotic in 17 patients. Our study contributes to the post marketing surveillance of major haemorrhagic complications associated with DOAC. It takes part to the knowledge about the course of this severe event in emergencies. Careful awareness in risk benefit assessment, especially in elderly, is needed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available After a subarachnoid haemorrhage (SAH, continuing impairment is common and may impact the person's life. There is a lack of knowledge regarding long-term consequences experienced.To explore experiences of the care and rehabilitation as well as the consequences and strategies used to cope with everyday life six years post SAH.An explorative interview study with a qualitative design. Individual interviews, with open ended questions, using an interview guide were performed with sixteen participants (mean age 63, 8 men, 8 women six years post SAH. Data was analyzed according to a descriptive thematic analysis, and themes were discovered inductively.Two major themes from the analysis, both including four sub-themes, were identified; these themes were consequences of the SAH and coping strategies. Participants were grateful to have survived the SAH and most were satisfied with their acute medical care. If discharged directly from the neurosurgical unit participants can feel abandoned. In contrast, participants who were referred to a rehabilitation clinic felt supported and informed. Cognitive problems, such as impaired memory and mental fatigue, were reported as still present six years post SAH. Coping strategies were; receiving support from family, society, employers, or technical equipment. At work, talking to colleagues and to taking breaks were common. Participants described hiding their symptoms from employers and friends, as well as trying to continue doing tasks in the same manner as prior to the SAH. If this was not possible, some refrained from doing these tasks. They went through a mourning process, fear, and worries.Participants reported several long-term consequences which impacted on their daily lives post SAH, and different coping strategies were used to cope with these problems. Participants reported lack of awareness regarding the consequences of SAH and stressed the importance of structured multidisciplinary follow-ups, which mostly

    To evaluate the association between serum levels of angiopoietins (Ang) during an early period (within 72 h) and clinical outcomes after aneurysmal subarachnoid haemorrhage (aSAH). This prospective study was conducted at Department of Neurosurgery, Tianjin Medical University General Hospital. Blood samples from 37 aSAH patients were collected at 8 h (or GOSE). Those with GOSE > 5 were counted as a good outcome while those with GOSE ≤ 5 had a poor outcome. A total of 37 patients with aSAH and 39 healthy controls (HC) were enrolled. The aSAH patients showed a significant rise of Ang-1 within 8 h as compared with HC. The outcomes were good (n = 15) and poor (n = 22). Serum Ang-1 at 8 h (or < 8 h), 24 h and 72 h in good outcomers showed significantly higher than that in poor outcomers [(52 ± 24) vs (37 ± 17) mg/L, (62 ± 26) vs (45 ± 17) mg/L, (107 ± 27) vs (72 ± 18) mg/L]. The serum level of Ang-1 at 8 h and 24 h was one of independent risk factors for aSAH patients by multiariable Logistic regression analysis [adjected OR (95% CI) 1.095 (1.015-1.181) and 1.109 (1.016-1.211)] (P < 0.05). High serum level of Ang-1 during an early period (within 72 h) was associated with good outcomers (r = 0.627, P < 0.001). The serum levels of angiopoietins are significantly altered in aSAH patients, especially higher in good outcomers. And abnormal levels of angiopoietins may affect early brain injury (EBI) after SAH, structural integrity and recovery of blood-brain barrier (BBB) and long-term outcomes in aSAH patients.

    Intravascular lymphomatosis (IVL) is a rare non-Hodgkin's lymphoma, usually of B cell lineage, characterized by massive angiotropic growth. The clinical presentation of IVL may include changes in mental status, non-localizing neurological deficits, seizures, fever of unknown origin and skin changes. Because of its rarity and the absence of specific diagnostic procedures except for cerebral biopsy, diagnosis is often postmortem. Brain MRI usually shows non-specific abnormalities. The purpose of this case report is to increase the knowledge of clinical and neuroimaging features of IVL by describing the findings observed in a 71-year-old patient. A 71-year-old male was admitted for right hemiparesis, acute cognitive impairment and febricula. A bone marrow biopsy resulted normal. He then developed a rapid progressive impairment of his mental status and left hemisoma motor seizures. Brain CT and MRI were interpreted as consistent with acute haemorrhagic leukoencephalopathy (AHLE), including multiple areas of restricted diffusion without gadolinium enhancement and a small focal area of gadolinium enhancement in the left temporal lobe white matter. The patient died within a few days and the autopsy led to the diagnosis of IVL. IVL may present with a variety of clinical signs and symptoms, including stroke and hemiparesis. IVL may mimic AHLE at brain MRI. However, the evidence of multiple areas of restricted diffusion without gadolinium enhancement and of a small area of gadolinium enhancement could have led to the correct diagnosis. IVL should be added to the differential diagnosis of AHLE at brain MRI. Copyright © 2012 Elsevier B.V. All rights reserved.

    2011-01-01

    A 76-year-old male suffering from nephrolithiasis developed a shock syndrome 5 days after extracorporal shock wave lithotripsy (ESWL). CT scan of the abdomen showed massive haemorrhage around the right kidney. Although nephrectomy was performed immediately, the haemorrhage could not be controlled. Numerous units of erythrocytes were transfused, but the patient died. The autopsy revealed massive retroperitoneal haemorrhage around the right kidney. The kidney showed a subcapsular haematoma and a rupture of the capsule. The right renal artery was dissected. The inferior vena cava was lacerated. Accordingly, a hemorrhagic shock as the cause of death was determined, which might mainly have resulted from the laceration of the inferior vena cava due to ESWL. ESWL seems to be a relatively non-invasive modality, but one of its severe complications is perirenal hematoma. The injuries of the blood vessels might have been caused by excessive shock waves. Subsequently, anticoagulation therapy had been resumed 3 days after EWSL, which might have triggered the haemorrhage. Physicians should note that a haemorrhage after an ESWL can occur and they should pay attention to the postoperative management in aged individuals especially when they are under anticoagulation therapy.

    The new methods of cannabis consumption (home made water pipe or "bang") may be responsible for fatal respiratory complications. We present a case, with fatal outcome, of a man of 19 years with no previous history other than an addiction to cannabis using "bang". He was admitted to intensive care with acute dyspnoea. A CT scan showed bilateral, diffuse alveolar shadowing. He was anaemic with an Hb of 9.3g/l. Bronchoalveolar lavage revealed massive alveolar haemorrhage. Investigations for infection and immunological disorder were negative and toxicology was negative except for cannabis. Antibiotic treatment was given and favourable progress allowed early discharge. Death occurred 15 days later due to alveolar haemorrhage following a further "bang" of cannabis. Autopsy showed toxic alveolar haemorrhage. The probable mechanism is pulmonary damage due to acid anhydrides released by the incomplete combustion of cannabis in contact with plastic. These acids have a double effect on the lungs: a direct toxicity with severe inflammation of the mucosa leading to alveolar haemorrhage and subsequently the acid anhydrides may lead to the syndrome of intra-alveolar haemorrhage and anaemia described in occupational lung diseases by Herbert in Oxford in 1979. It manifests itself by haemoptysis and intravascular haemolysis. We draw attention to the extremely serious potential consequences of new methods of using cannabis, particularly the use of "bang" in homemade plastic materials. Copyright © 2011 SPLF.

    Nontraumatic spontaneous atlanto-occipital dislocation (AOD) is rare. In this report, we discuss the technical steps of condylar joint fusion and stabilization (by screws and plates) in nontraumatic AOD. To the best of our knowledge, it is the first report of such techniques. A young girl and a young man with progressive quadriparesis due to nontraumatic spontaneous atlanto-occipital dislocation were managed by microsurgical reduction, fusion, and stabilization of the joint by occipital condylar and C1 lateral mass screw and plate fixation after mobilization of vertebral artery. In both cases, condylar joints fixation and fusion were done successfully. Condylar joint stabilization and fusion may be a good or alternative option for AOD. Copyright © 2017 Elsevier Inc.

    Haemorrhagic cystitis is an uncommon and, in its severe form, potentially life-threatening complication of haematopoietic stem cell transplantation or cancer therapy in children. The severe form involves macroscopic haematuria with blood clots, urinary obstruction and/or renal impairment. There are many therapeutic options to treat acute haemorrhage, but only recombinant factor VII has a high level of clinical evidence in children. Supraselective vesical artery embolization (SVAE) is an increasingly used therapeutic procedure for controlling haemorrhage in adults, but is less commonly used in children. This might be due to several factors, such as the invasive nature of the procedure, lack of appropriate medical experience and possible long-term side effects. We present three cases of children successfully treated by means of effective SVAE.

    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.

  11. What are the current therapeutic options for haemorrhagic strokes

    2010-01-01

    The Factor Seven for Acute Haemorrhagic Stroke Trial (FAST) and Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trial (INTERACT). Intracerebral haemorrhage (ICH) is the most devastating form of stroke carrying a mortality of up to 40% at one month. In our part of the world the levels of uncontrolled hypertension pose a greater risk of ICH for our population where ICH is about 30% of all strokes compared to 14% in developed countries. There is evidence to suggest that haematoma expansion occurs in as many as 70% of patients. This expansion translates into increased disability and death. Most of this expansion is within the initial three hours. Also early elevation of blood pressure (BP) is very common after ICH and many studies have highlighted an association between elevated BP post ICH and poor outcomes. The reason for this is postulated to be an increase in both the size of the haematoma and perilesional oedema. (author)

The patient presented with a 7-month history of low back pain and bilateral sciatica. Magnetic resonance imaging enabled a correct preoperative diagnosis revealing a nodular, well-circumscribed epidural mass with peripheral enhancement and signal intensities consistent with chronic hematoma, which extended from L2 to L3. Laminectomy of L2-L3 was performed and the hematoma was totally resected. Histological examination of the surgical specimen demonstrated a chronic encapsulated hematoma. No evidence of vascular malformation was found. The patient recovered fully after surgical treatment. (orig.)

    Technetium-99m pyrophosphate (Tc-PYP) imaging was performed in five patients with acute renal failure associated with nontraumatic rhabdomyolysis. Four patients had phencyclidine intoxication and one had viral pneumonia. During the acute phase, marked uptake of pyrophosphate was seen in all patients in several muscle groups, but always in the thigh adductors. The results show that phencyclidine intoxication can result in diffuse muscle uptake of Tc-PYP without overt evidence of muscle injury. Tc-PYP imaging may provide a clue to the cause of acute renal failure in patients with suspected rhabdomyolysis in whom elevations of serum creatine phosphokinase concentrations are equivocal

    The medical records of 39 dogs with acute nontraumatic hemoabdomen were identified and reviewed. Anemia and hypoalbuminemia were identified in 36/37 (97%) and 25/33 (76%) dogs, respectively. Coagulopathies were identified in 26/31 (84%) dogs. When a definitive diagnosis was obtained, malignant neoplasia was diagnosed most frequently and occurred in 24/30 (80%) dogs. Hemangiosarcoma accounted for 21/30 (70%) diagnoses. Sixteen dogs underwent exploratory laparotomy, of which seven (44%) survived the perioperative period. Of the dogs that did not undergo surgery, 9/23 (39%) survived to be discharged from the hospital.

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

    We report magnetic resonance imaging findings of massive spinal subarachnoid hemorrhage (SAH) caused by repeated lumbar punctures during spinal anesthesia in a 36-year-old man. The signal intensities of spinal SAH were similar to those of the conus medullaris on both T1-and T2-weighted spin-echo images. Although spinal SAH is hardly recognized on MR, spinal SAH of sufficient amount may cause alteration of the cerebrospinal fluid signal.

    Background Natriuresis with polyuria is common after aneurysmal subarachnoid hemorrhage (aSAH). Previous studies have shown an increased risk of symptomatic cerebral vasospasm or delayed cerebral ischemia (DCI) in patients with hyponatremia and/or the cerebral salt wasting syndrome (CSW). However, natriuresis may occur in the absence of hyponatremia or hypovolemia and it is not known whether the increase in DCI in patients with CSW is secondary to a concomitant hypovolemia or because the phys...

    Quantitative estimation of the hemorrhage volume associated with aneurysm rupture is a new tool of assessing prognosis. To determine the prognostic value of the quantitative estimation of the amount of bleeding after aneurysmal subarachnoid hemorrhage, as well the relative importance of this factor related to other prognostic indicators, and to establish a possible cut-off value of volume of bleeding related to poor outcome. A prospective cohort of 206 patients consecutively admitted with the diagnosis of aneurysmal subarachnoid hemorrhage to Hospital 12 de Octubre were included in the study. Subarachnoid, intraventricular, intracerebral, and total bleeding volumes were calculated using analytic software. For assessing factors related to prognosis, univariate and multivariate analysis (logistic regression) were performed. The relative importance of factors in determining prognosis was established by calculating their proportion of explained variation. Maximum Youden index was calculated to determine the optimal cut point for subarachnoid and total bleeding volume. Variables independently related to prognosis were clinical grade at admission, age, and the different bleeding volumes. The proportion of variance explained is higher for subarachnoid bleeding. The optimal cut point related to poor prognosis is a volume of 20 mL both for subarachnoid and total bleeding. Volumetric measurement of subarachnoid or total bleeding volume are both independent prognostic factors in patients with aneurysmal subarachnoid hemorrhage. A volume of more than 20 mL of blood in the initial noncontrast computed tomography is related to a clear increase in poor outcome risk. : aSAH, aneurysmal subarachnoid hemorrhage.

    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)

    Full Text Available Two unlike metals near one another can break down as they move toward electrochemical equilibrium resulting in galvanic corrosion. We describe a case of electrochemical corrosion resulting in pseudarthrosis, followed by instrumentation failure leading to subarachnoid hemorrhage. A 53-year-old female with a history of cervical instability and two separate prior cervical fusion surgery with sublaminar cables presented with new onset severe neck pain. Restricted range of motion in her neck and bilateral Hoffman's was noted. X-ray of her cervical spine was negative. A noncontrast CT scan of her head and neck showed subarachnoid hemorrhage in the prepontine and cervicomedullary cisterns. Neurosurgical intervention involved removal of prior stainless steel and titanium cables, repair of cerebrospinal fluid leak, and nonsegmental C1–C3 instrumented fusion. She tolerated the surgery well and followed up without complication. Galvanic corrosion of the Brook's fusion secondary to current flow between dissimilar metal alloys resulted in catastrophic instrumentation failure and subarachnoid hemorrhage.

    Churg-Strauss syndrome (CSS) is a vasculitis syndromes and is only rarely complicated by subarachnoid hemorrhage. In the current report, we describe a case of CSS with subarachnoid hemorrhage, which showed a favorable outcome following conservative treatment. A 68-year-old man with CSS on maintenance steroid therapy underwent MRI/A during tinnitus aggravation, and showed dilation of the left middle cerebral artery and stenosis of the peripheral area of the right vertebral artery. After 2 months, he presented sudden pain in the occipitocervical area, and CT revealed subarachnoid hemorrhage. Intracranial 3D CT-A and MRI/A showed the development of a protrusion at the base of the left anterior cerebral artery. Although both findings suggested cerebral artery dissection, the source of hemorrhage could not be identified. The 2009 Japanese Guidelines for the Management of Stroke recommends early diagnosis and treatment of hemorrhagic cerebral artery dissection because of the high risk of re-bleeding. However, considering the risks of vasculitis aggravation, development of systemic complications, and recurrence, conservative treatment was selected. In addition, owing to the risk of complications associated with the frequent use of iodinated contrast agents and angiography procedures, patient was followed up using MRI. His course was favorable, and he was discharged despite mild right abducens paralysis. When patients with hemorrhagic cerebral artery dissection have a history of allergic diseases, CCS should be considered; conservative treatment consisting of rest, strict blood pressure control, and steroid therapy may be the most appropriate option for certain patients.

    The CT findings of 98 patients with subarachnoid hemorrhage due to aneurysmal rupture were analyzed and compared with cerebral angiography for the purpose of preangiographic prediction of aneurysmal location as well as evaluation of the CT features corresponding to the vasospasm or ischemic neurologic dysfunctions. The results were as follows: 1.Aneurysms could be identified on initial cerebral angiography in 82 out of 98 patients with subarachnoid hemorrhage and anterior communicating artery aneurysms were most common (42 cases), followed by MCA, posterior communicating artery, ICA, basilar artery in order of frequency. 2.The CT findings of those patients were hemorrhage in subarachnoid space (69%), localized hematoma (47%), ventricular dilatation (31%), enhancing nodule (23%), cisternal enhancement (20%), cerebral infarction (15%), ventricular hemorrhage (14%), and epidural hemorrhage (3%). 3.Localized hematoma was more prevalent in anterior communicating artery aneurysm rupture (54%), and less frequently in MCA, posterior communicating artery and ICA aneurysms. 4.Most of aneurysmal sac could be identified as enhancing nodule on CT when the real size were over 1 cm. 5.The size of ruptured aneurysm could be predicted in many patients with ACA and MCA aneurysm according to the CT features such as hemorrhagic patterns, location of hematomas or enhancing nodules. 6.Localized hematoma or blood clots and cerebral infarction are considered to be the CT features corresponding to the angiographic vasospasm

    The open abdomen is increasingly used for the treatment and prevention of abdominal compartment syndrome. The leading non-traumatic conditions that may cause abdominal compartment syndrome requiring surgical decompression include secondary peritonitis, ruptured abdominal aortic aneurysm and severe acute pancreatitis. Patients may also end up with the open abdomen when the laparotomy wound cannot be closed without tension because of excessive visceral swelling. Also, surgical complications such as laparotomy wound dehiscence, may require temporary abdominal closure techniques. In critically ill surgical patients and in situations when second-look laparotomy is mandatory the open abdomen can be utilized in a preventive manner like in damage control trauma surgery. Underlying disease and the indication for the open abdomen significantly contributes to outcome of patient with open abdomen. Non-traumatic aetiology of the open abdomen is associated with lower likelihood of primary fascial closure and higher rate of open abdomen related complications compared with traumatic aetiology. A number of temporal abdominal closure techniques have been described. Ideally, temporal abdominal closure technique should prevent the development of recurrent abdominal compartment syndrome and facilitate later primary fascia closure with low complication rate. Although fascial closure rate varies between techniques, there are few evidence-based data to support one technique over another. However, recent evolution of temporary abdominal closure techniques have decreased the number of patients with frozen abdomen and reduced the need for planned hernia management. Highest fascial closure rates have been achieved with vacuum-assisted closure systems and systems that provide continuous fascial traction.

    To report a case of nontraumatic corneal perforation managed with a tectonic drape patch. Interventional case report. A 60-year-old patient with a corneal scar in his left eye likely secondary to herpes simplex virus interstitial keratitis underwent laser peripheral iridotomy for narrow angles. He developed progressive thinning of the cornea overlying the scar that led to a descemetocele and then ultimately a 1.2- × 1.7-mm perforation. Intraoperatively, several attempts were made to seal the perforation with cyanoacrylate glue, but the wound continued to leak. Sterile plastic drape that was on the surgical field was fashioned into a 2-mm-diameter patch, and the peripheral edge of the tectonic drape patch was glued over the perforation, successfully sealing the cornea. One week later, the drape patch was intact without leak, and a penetrating keratoplasty was carried out without complication. Tectonic drape patch technique for nontraumatic corneal perforations in which there is tissue loss is a viable temporizing option when cyanoacrylate glue alone fails and when there is no corneal tissue or amniotic membrane available to close the wound.

    To find out the frequency of non-traumatic anterior knee pain in secondary school students of Lahore, Pakistan. Methodology: This observational study was conducted among 350 students of secondary school of Lahore during a 3 months period. Both males and females of age 11-17 years were included in the study. A questionnaire was completed which included demographic data, Numeric Rating scale (NRS) and Kujala Scale. The data were being analyzed using SPSS version 21.0. Results: Out of 350 secondary school students, 145 (41%) had anterior knee pain (AKP). Twenty seven (19%) had pain in the left knee only, 54 (37%) had pain in right knee only while 64 (44%) had pain in both knees. The incidence of AKP was highest among 11 to 15 years old students. Moreover, the girls reported high frequency of AKP then the boys. The activities that were affected because of AKP included running, walking, stair climbing and jumping. Conclusion: Non-traumatic AKP is common among students of age 11-17 years, with a peak during adolescence (11-15). This pain not only affects the sports activities but also affects the activity of daily livings. (author)

    OBJECTIVE: To establish the clinical characteristics, aetiology, neuro-physiological characteristics, imaging findings and other investigations in a cohort of patients with non-traumatic brachial plexopathy (BP). METHODS: A 3-year retrospective study of patients with non-traumatic BP identified by electromyography (EMG) and nerve conduction studies (NCS). Clinical information was retrieved from patients\\' medical charts. RESULTS: Twenty-five patients were identified. Causes of BP included neuralgic amyotrophy (NA) (48%), neoplastic (16%), radiation (8%), post infectious (12%), obstetric (4%), rucksack injury (4%), thoracic outlet syndrome (4%) and iatrogenic (4%). Patients with NA presented acutely in 50%. The onset was subacute in all others. Outcome was better for patients with NA. All patients with neoplastic disease had a previous history of cancer. MRI was abnormal in 3\\/16 patients (18.8%). PET scanning diagnosed metastatic plexopathy in two cases. CONCLUSIONS: NA was the most common cause of BP in our cohort and was associated with a more favourable outcome. The authors note potentially discriminating clinical characteristics in our population that aid in the assessment of patients with brachial plexopathies. We advise NCS and EMG be performed in all patients with suspected plexopathy. Imaging studies are useful in selected patients.

    Prenatal features of isolated cerebellar haemorrhagic lesions have not been sufficiently characterised. We aimed to better define their MR imaging characteristics, documenting the location, extension, evolution stage and anatomic sequelae, and to better understand cerebellar haemorrhage pathophysiology. We screened our foetal MR imaging database (3200 cases) for reports of haemorrhagic lesions affecting only the cerebellum (without any supratentorial bleeding or other clastic lesions), defined as one of the following: T2-weighted hypointense or mixed hypo-/hyperintense signal; rim of T2-weighted hypointense signal covering the surface of volume-reduced parenchyma; T1-weighted hyperintense signal; increased DWI signal. Seventeen cases corresponded to the selection criteria. All lesions occurred before the 26th week of gestation, with prevalent origin from the peripheral-caudal portion of the hemispheres and equal frequency of unilateral/bilateral involvement. The caudal vermis appeared affected in 2/3 of cases, not in all cases confirmed postnatally. Lesions evolved towards malformed cerebellar foliation. The aetiology and pathophysiology were unknown, although in a subset of cases intra- and extracranial venous engorgement seemed to play a key role. Onset from the peripheral and caudal portion of the hemispheres seems characteristic of prenatal cerebellar haemorrhagic lesions. Elective involvement of the peripheral germinal matrix is hypothesised. (orig.)

    The aim of this study was to evaluate a possible relationship between lunar cycles and haemorrhagic complication rate in surgery. The possible relationship between moon phases and surgical outcome was tested by evaluating the haemorrhagic complication rate for 18,760 patients who underwent surgery between January 2001 and December 2008 at the National Institute for Cancer Research in Genoa. A total of 103 lunar phases were considered using Chi-square (χ 2 ) test analysis, and patients were allocated a surgery date. One hundred and sixty-seven haemorrhagic complications were observed. Three hundred and nine new moon phase days were analysed and 12 incidences of complications detected, with a 3.9% complication rate per day. In the waxing moon phase, 1184.5 d were analysed with 68 incidences of complications at a daily rate of 5.7%. In the full moon phase there was a 4.9% complication rate per day (15 incidences in 309 d), whereas in the waning moon phase, the 6% percentage rate per day resulted from 72 incidences in 1184.5 d. No statistically significant correlations were found between moon cycles and postoperative haemorrhagic complications (p = .50).

    Six patients with haemorrhage into intracranial neuromas were studied by computed tomography (CT) and magnetic resonance imaging (MRI) at 0.5 T with spin-echo pulse sequences. The nature of the tumour and the presence of a haematoma were confirmed by surgery and microscopic examination in all cases. Four neuromas arose from the acoustic nerves and two from the trigeminal. Four of the six patients suffered from sudden onset or rapid worsening of symptoms including headache, vertigo and/or hemifacial motor and sensory disturbances. CT in the acute stage revealed a hyperdense area or a fluid-fluid level (FFL). The hyperdense area disappeared on CT repeated in the chronic stage. On MRI in subacute and chronic stages the haemorrhage showed hyperintensity on both T1 and T2 weighting in five cases examined between 16 and 46 days after the onset, and isointensity on T1 weighting and an FFL on T2 weighting in one case examined 12 days after the onset of symptoms. A well-defined low intensity rim indicating prior haemorrhage was observed on T2-weighted images in three cases. MRI was more effectie than CT in detecting haemorrhage into the tumours and in staging it. (orig.)

    AIM: To present the findings of uterine artery embolization (UAE) in the management of obstetric haemorrhage. MATERIALS AND METHODS: From October 1999 to February 2003, 10 women with postpartum haemorrhage (n=7) and post-abortion haemorrhage with placenta accreta (n=3), were referred to our department for pelvic angiography and possible arterial embolization. RESULTS: Angiography revealed engorged and tortuous uterine arteries in all patients; and contrast medium extravasation in three patients. Eight patients (three with and five without detectable active bleeding) then underwent bilateral UAE. Medium-sized (250-355 {mu}m) polyvinyl alcohol particles were injected via a coaxial catheter into the uterine arteries, followed by gelatin sponge pieces via a 4 F Cobra catheter. Microcoil devascularization was also performed in the two patients with visible, active bleeding. The vaginal bleeding resolved in all patients, without any ischaemic complications. At follow-up, all patients who underwent UAE had normal menstruation; three of them subsequently gave birth to full-term healthy babies. CONCLUSION: Selective UAE by the coaxial method is safe and effective to control obstetric haemorrhage, with the potential to preserve fertility.

    To compare serum lipid profile between patients of ischaemic and haemorrhagic strokes. Study Design: Cross sectional, comparative study. Place and Duration of Study: Military Hospital, Rawalpindi, from August 2004 to February 2005. Methodology: Patients with diagnosis of stroke comprising 100 consecutive patients each of ischaemic and haemorrhagic strokes were included in the study while patients on lipid lowering therapy were excluded from study. To determine the subtype of stroke, clinical examination followed by CT scan of brain was done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. Statistical analysis was done by comparison of lipid profile in two subgroups, using proportion test for any significant difference. Results: The mean age at presentation of patients with stroke was 64.2+-12 years with a male to female ratio of 3.6:1. In 100 ischaemic stroke patients, raised serum total cholesterol was seen in 42, triglyceride in 04, LDL-cholesterol in 05 and VLDL-cholesterol in 07 patients. Serum HDL-cholesterol was below the normal reference in 31 cases. On the other hand, serum total cholesterol and triglycerides was raised in 05 patients each, LDL-cholesterol in 09 and VLDL-cholesterol in 03 patients of haemorrhagic stroke. Serum HDL-cholesterol was below normal in 04 patients of haemorrhagic stroke. On comparison, there were significantly greater number of patients with raised serum cholesterol and low HDL-cholesterol in ischaemic stroke than haemorrhagic stroke (p < 0.05). No statistical significance was found on comparing serum values of ischaemic and haemorrhagic stroke for triglycerides, LDL-cholesterol and VLDL-cholesterol. Conclusion: Ischaemic stroke patients had high serum total cholesterol and lower HDL-cholesterol levels as compared to

    Retrospective chart review. To identify factors predictive of survival after spinal cord injury (SCI). Tertiary care institution. Multiple-variable Cox proportional hazards regression analysis for 759 patients with SCI (535 nontraumatic and 221 traumatic) included age, sex, completeness of injury, level of injury, functional independence measure (FIM) scores, rehabilitation length of stay and SCI cause. Estimated years of life lost in the decade after injury was calculated for patients vs uninjured controls. Median follow-up was 11.4 years. Population characteristics included paraplegia, 58%; complete injury, 11%; male sex, 64%; and median rehabilitation length of stay, 16 days. Factors independently predictive of decreased survival were increased age (+10 years; hazard ratio (HR (95% CI)), 1.6 (1.4-1.7)), male sex (1.3 (1.0-1.6)), lower dismissal FIM score (-10 points; 1.3 (1.2-1.3)) and all nontraumatic causes. Metastatic cancer had the largest decrease in survival (HR (95% CI), 13.3 (8.7-20.2)). Primary tumors (HR (95% CI), 2.5 (1.7-3.8)), vascular (2.5 (1.6-3.8)), musculoskeletal/stenosis (1.7 (1.2-2.5)) and other nontraumatic SCI (2.3 (1.5-3.6)) were associated with decreased survival. Ten-year survival was decreased in nontraumatic SCI (mean (s.d.), 1.8 (0.3) years lost), with largest decreases in survival for metastatic cancer and spinal cord ischemia. Age, male sex and lower dismissal FIM score were associated with decreased survival, but neither injury severity nor level was associated with it. Survival after SCI varies depending on SCI cause, with survival better after traumatic SCI than after nontraumatic SCI. Metastatic cancer and vascular ischemia were associated with the greatest survival reduction.

    Nontraumatic osteonecrosis of the femoral head (ONFH) is treated with a series of methods. High-energy extracorporeal shock wave therapy (ESWT) is an option with promising mid-term outcomes. The objective of this study was to determine the long-term outcomes of ESWT for ONFH. Fifty-three hips in 39 consecutive patients were treated with ESWT in our hospital between January 2005 and July 2006. Forty-four hips in 31 patients with stage I-III nontraumatic ONFH, according to the Association Research Circulation Osseous (ARCO) system, were reviewed in the current retrospective study. The visual analog pain scale (VAS), Harris hip score, radiography, and magnetic resonance imaging were used to estimate treatment results. The progression of ONFH was evaluated by imaging examination and clinical outcomes. The results were classified as clinical success (no progression of hip symptoms) and imaging success (no progression of stage or substage on radiography and MRI). The mean follow-up duration was 130.6 months (range, 121 to 138 months). The mean VAS decreased from 3.8 before ESWT to 2.2 points at the 10-year follow-up (p < 0.001). The mean Harris hip score improved from 77.4 before ESWT to 86.9 points at the 10-year follow-up. The clinical success rates were 87.5% in ARCO stage I patients, 71.4% in ARCO stage II patients, and 75.0% in ARCO stage III patients. Imaging success was observed in all stage I hips, 64.3% of stage II hips, and 12.5% of stage III hips. Seventeen hips showed progression of the ARCO stage/substage on imaging examination. Eight hips showed femoral head collapse at the 10-year follow-up. Four hips in ARCO stage III and one hip in ARCO stage II were treated with total hip arthroplasty during the follow-up. Three were performed 1 year after ESWT, one at 2 years, and one at 5 years. The results of the current study indicated that ESWT is an effective treatment method for nontraumatic ONFH, resulting in pain relief and function restoration

    Postpartum haemorrhage (PPH) - heaving bleeding within the first 24 hours after giving birth - is one of the main causes of death of women after childbirth. Antifibrinolytics, primarily tranexamic acid (TXA), have been shown to reduce bleeding in surgery and safely reduces mortality in trauma patients with bleeding without increasing the risk of adverse events.An earlier Cochrane review on treatments for primary PPH covered all the various available treatments - that review has now been split by types of treatment. This new review concentrates only on the use of antifibrinolytic drugs for treating primary PPH. To determine the effectiveness and safety of antifibrinolytic drugs for treating primary PPH. We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (28 May 2017) and reference lists of retrieved studies. Randomised controlled trials (RCTs), including cluster-randomised trials of antifibrinolytic drugs (aprotinin, TXA, epsilon-aminocaproic acid (EACA) and aminomethylbenzoic acid, administered by whatever route) for primary PPH in women.Participants in the trials were women after birth following a pregnancy of at least 24 weeks' gestation with a diagnosis of PPH, regardless of mode of birth (vaginal or caesarean section) or other aspects of third stage management.We have not included quasi-randomised trials, or cross-over studies. Studies reported as abstracts have not been included if there was insufficient information to allow assessment of risk of bias.In this review we only identified studies looking at TXA. Two review authors independently extracted data from each study using an agreed form. We entered data into Review Manager software and checked for accuracy.For key review outcomes, we rated the quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach. Three trials (20,412 women) met our inclusion criteria. Two trials

    Postpartum haemorrhage (PPH) (bleeding from the genital tract after childbirth) is a major cause of maternal mortality and disability, particularly in under-resourced areas. In these settings, uterotonics are often not accessible. There is a need for simple, inexpensive techniques which can be applied in low-resourced settings to prevent and treat PPH. Uterine massage is recommended as part of the routine active management of the third stage of labour. However, it is not known whether it is effective. If shown to be effective, uterine massage would represent a simple intervention with the potential to have a major effect on PPH and maternal mortality in under-resourced settings. To determine the effectiveness of uterine massage after birth and before or after delivery of the placenta, or both, to reduce postpartum blood loss and associated morbidity and mortality. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013). All published, unpublished and ongoing randomised controlled trials comparing uterine massage alone or in addition to uterotonics before or after delivery of the placenta, or both, with non-massage. Two researchers independently considered trials for eligibility, assessed risk of bias and extracted the data using the agreed form. Data were checked for accuracy. The effect of uterine massage commenced before or after placental delivery were first assessed separately, and then the combined for an overall result. This review included two randomised controlled trials. The first trial included 200 women who were randomised to receive uterine massage or no massage following delivery of the placenta, after active management of the third stage of labour including use of oxytocin. The numbers of women with blood loss more than 500 mL was small, with no statistically significant difference (risk ratio (RR) 0.52, 95% confidence interval (CI) 0.16 to 1.67). There were no cases of retained placenta in either group. The mean

    Full Text Available Subarachnoid hemorrhage is frequently associated with poor prognoses. Three different hemodynamic phases were identified during subarachnoid hemorrhage: oligemia, hyperemia, and vasospasm. Each phase is associated with brain metabolic changes. In this review, we correlated the hemodynamic phases with brain metabolism and potential treatment options in the hopes of improving patient prognoses.

    Full Text Available A 72-year-old male patient underwent mobile-bearing posterior-stabilized total knee arthroplasty for osteoarthritis. He experienced a nontraumatic polyethylene tibial insert cone fracture 27 months after surgery. Scanning electron microscopy of the fracture surface of the tibial insert cone suggested progress of ductile breaking from the posterior toward the anterior of the cone due to repeated longitudinal bending stress, leading to fatigue breaking at the anterior side of the cone, followed by the tibial insert cone fracture at the anterior side of the cone, resulting in fracture at the base of the cone. This analysis shows the risk of tibial insert cone fracture due to longitudinal stress in mobile-bearing posterior-stabilized total knee arthroplasty in which an insert is designed to highly conform to the femoral component.

    Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. Although low bone density may be present concurrently, it is not the underlying cause of subchondral insufficiency fractures in the majority of patients. Patients with subchondral insufficiency fracture characteristically have unremarkable plain radiographs, while MRI examination may reveal extensive bone marrow oedema and subchondral bone collapse. This article presents a 51-year-old postmenopausal woman, a physician, who had subchondral insufficiency fractures of the knee associated with prolonged standing during clinical work. She was treated with partial weight bearing on crutches until 14 months after the injury, viscosupplementation at 4 months to treat osteoarthritis and teriparatide treatment to improve bone healing at 7 months. By 26 months after the injury, she tolerated independent walking with a fabric knee support but still experienced mild posterolateral knee pain and numbness on prolonged standing. 2015 BMJ Publishing Group Ltd.

    Full Text Available This paper reports a case of fatigue fracture of the femoral component in a cruciate-retaining cemented total knee arthroplasty (TKA. A 64-year-old man had undergone a primary TKA for osteoarthritis 10 years previously at another institution using the PFC-Sigma prosthesis. The patient recovered fully and was back to his regular activities. He presented with a history of sudden onset pain and locking of the left knee since the preceding three months. There was no history of trauma, and the patient was mobilizing with difficulty using crutches. Radiographs revealed fracture of the posterior condyle of the femoral prosthesis. Revision surgery was performed as an elective procedure revealing the broken prosthesis. The TC3RP-PFC revision prosthesis was used with a medial parapatellar approach. The patient recovered fully without any squeal. Mechanical failure of the knee arthroplasty prosthesis is rare, and nontraumatic fracture of the femoral metallic component has not been reported before.

    Non-traumatic chest pain is a common symptom in patients who present in the emergency department. From a clinical point of view, it is important to differentiate cardiac chest pain from non-cardiac chest pain (NCCP). Among the plethora of potential causes of NCCP, life-threatening diseases, such as aortic dissection, pulmonary embolism, tension pneumothorax, and esophageal rupture, must be differentiated from non-life threatening causes. The majority of NCCP, however, is reported to be benign in nature. The presentation of pain plays an important role in narrowing the differential diagnosis and initiating further diagnostic management and treatment. As the benign causes tend to recur, and may lead to patient anxiety and great costs, a meticulous evaluation of the patient is necessary to diagnose the underlying disorder or disease.

    Two different series collected at the University Hospital of Freiburg are presented as a basis for the critical appraisal of available imaging tests and their correlation with anatomic pain sites. The first series comprises 284 patients of non-traumatic acute abdomen admitted to the emergency department during 1990. The radiological approach revealed an increased use of immediate ultrasound (58%) followed by plain film radiography (53%), contrast studies (15%), and computed tomography (9.8%). Five groups of entities were identified according to the diagnostic imaging procedure prior to surgery. In a second series, the clinical presentation, the distribution and the efficacy of imaging studies for the confirmation of acute mesenteric ischemia were evaluated in 55 patients over a period of 14 years. A reduced mortality rate emphasizes the value of early and agressive diagnosis and angiographic management. (orig.)

    Magnetic resonance imaging (MRI) using 3.0 T scanners in the clinical environment is in its infancy and is only available at a limited number of sites worldwide. There is great interest amongst radiologists about the perceived benefits of clinical imaging at 3.0 T; however, it remains to be seen whether the theoretical advantages will bring real gains. MRI in patients with non-traumatic intracranial hemorrhage (ICH) is difficult, yet, these patients benefit from non-invasive angiography. Conventional catheter angiography (CCA) remains the reference standard for excluding/confirming the presence of intracranial vascular abnormalities, but MR angiography at 3.0 T may offer opportunities for significant changes in patient management. We present our experiences of using 3.0 T MR angiography in 27 patients with acute or early subacute ICH. (orig.)

    Full Text Available People with epilepsy are more accident prone than the non-epilepsy population. Bone fractures are most often due to seizure-related falls. However, seizures themselves, in particular generalized tonic-clonic seizures, may also cause fractures, e.g. of the thoracic spine. Here, I present a man who developed focal epilepsy following a subarachnoidal hemorrhage. During a focal motor seizure with left-sided convulsions and preserved consciousness that lasted 2 hrs, he sustained a femoral neck fracture. In persons with low mineral density, as in this case, contractions associated with simple focal motor seizures may be sufficient to give rise to such a severe complication.

    Rhabdomyolysis is a relatively rare condition, but its clinical consequences are frequently dramatic in terms of both morbidity and mortality. Although no consensus has been reached so far about the precise definition of this condition, the term rhabdomyolysis describes a rapid breakdown of striated, or skeletal, muscle. It is hence characterized by the rupture and necrosis of muscle fibers, resulting in release of cell degradation products and intracellular elements within the bloodstream and extracellular space. Notably, the percentage of patients with rhabdomyolysis who develop acute kidney injury, the most dramatic consequence, varies from 13% to over 50% according to both the cause and the clinical and organizational setting where they are diagnosed. Despite direct muscle injury (i.e., traumatic rhabdomyolysis) remains the most common cause, additional causes, frequently overlapping, include hypoxic, physical, chemical or biological factors. The conventional triad of symptoms includes muscle pain, weakness and dark urine. The laboratory diagnosis is essentially based on the measurement of biomarkers of muscle injury, being creatine kinase (CK) the biochemical "gold standard" for diagnosis, and myoglobin the "gold standard" for prognostication, especially in patients with non-traumatic rhabdomyolysis. The essential clinical management in the emergency department is based on a targeted intervention to manage the underlying cause, combined with infusion of fluids and eventually sodium bicarbonate. We will present and discuss in this article the pathophysiological and clinical features of non-traumatic rhabdomyolysis, focusing specifically on Emergency Department (ED) management.

    Background: Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants. Purpose: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated with an increased likelihood of experiencing pain. Study Design: Descriptive epidemiology study. Methods: A self-report survey focusing on the prevalence of pain not associated with a traumatic event in female high school youth volleyball players was developed. Survey questions were formulated by certified athletic trainers, experienced volleyball coaches, and biomechanics experts. Surveys were received from 175 healthy, active high school volleyball players in Iowa, South Dakota, and Minnesota. Results: Forty percent (70/175) of active high school volleyball players remembered experiencing shoulder pain not related to traumatic injury, but only 33% (23/70) reported taking time off to recover from the pain. Based on these self-reported data, activities associated with significantly increased risk of nontraumatic shoulder pain included number of years playing competitive volleyball (P = .01) and lifting weights out of season (P = .001). Players who reported multiple risk factors were more likely to experience nontraumatic shoulder pain. Conclusion: When using time off for recovery as the primary injury criterion, we found that the incidence of shoulder pain is more than twice as high as the incidence of injury reported by previous studies. Findings also indicated that the incidence of shoulder pain

    Full Text Available BACKGROUND AND OBJECTIVES: Painful phenomenon is one of the most important and complex experiences. Phentolamine is a non-selective alpha-adrenergic antagonist. The objective of this study was to compare the effect of increasing doses of phentolamine into subarachnoid space in rats in the modulation of painful phenomenon. METHODS: 84 male Wistar rats were divided into formalin and plantar incision groups, subdivided into six subgroups (n = 7. Control group received only saline (10 µL; active subgroups received phentolamine 10 µmg (GF10, 20 mg (GF20, 30 mg (GF30, 40 mg (GF40, and 50 g (GF50. In formalin group, pain was induced by injection of 50 µL of 2% formalin in dorsal region of right posterior paw. In plantar incision group, pain was induced by plantar incision and evaluated using von Frey filaments. Induction and maintenance of anesthesia were performed with 3% halothane for catheter placement into subarachnoid space and plantar incision. Statistical analysis was performed using the JMP program from SAS with 5% significance level. RESULTS: Phentolamine at doses of 20 and 30 g increased the algesic response in the intermediate phase of the formalin test. In plantar incision test, it had hyperalgic effect on first, third, fifth, and seventh days at a dose of 10 g and on first, third, and fifth days at a dose of 20 g and on fifth day at a dose of 30 g. CONCLUSION: Subarachnoid administration of phentolamine showed hyperalgesic effect, possibly due to the involvement of different subclasses of alpha-adrenergic receptors in modulating pain pathways.

    Lactate is central for the regulation of brain metabolism and is an alternative substrate to glucose after injury. Brain lactate metabolism in patients with subarachnoid hemorrhage has not been fully elucidated. Thirty-one subarachnoid hemorrhage patients monitored with cerebral microdialysis (CMD) and brain oxygen (PbtO(2)) were studied. Samples with elevated CMD lactate (>4 mmol/L) were matched to PbtO(2) and CMD pyruvate and categorized as hypoxic (PbtO(2) 119 μmol/L) versus nonhyperglycolytic. Median per patient samples with elevated CMD lactate was 54% (interquartile range, 11%-80%). Lactate elevations were more often attributable to cerebral hyperglycolysis (78%; interquartile range, 5%-98%) than brain hypoxia (11%; interquartile range, 4%-75%). Mortality was associated with increased percentage of samples with elevated lactate and brain hypoxia (28% [interquartile range 9%-95%] in nonsurvivors versus 9% [interquartile range 3%-17%] in survivors; P=0.02) and lower percentage of elevated lactate and cerebral hyperglycolysis (13% [interquartile range, 1%-87%] versus 88% [interquartile range, 27%-99%]; P=0.07). Cerebral hyperglycolytic lactate production predicted good 6-month outcome (odds ratio for modified Rankin Scale score, 0-3 1.49; CI, 1.08-2.05; P=0.016), whereas increased lactate with brain hypoxia was associated with a reduced likelihood of good outcome (OR, 0.78; CI, 0.59-1.03; P=0.08). Brain lactate is frequently elevated in subarachnoid hemorrhage patients, predominantly because of hyperglycolysis rather than hypoxia. A pattern of increased cerebral hyperglycolytic lactate was associated with good long-term recovery. Our data suggest that lactate may be used as an aerobic substrate by the injured human brain.

    Six patients with acquired spinal subarachnoid cysts secondary to epidural anesthesia were evaluated with MR imaging (seven patients) and intraoperative US (three patients). The cysts were located in the lower cervical and thoracic spine. Adhesions and irregularity of the cord surface were frequently noted. Associated intramedullary lesions, including intramedullary cysts and myelomalacia, were seen in two of the patients. Arachnoiditis was unsuspected clinically in three patients, and MR imaging proved to be the diagnostic examination that first suggested the cause of the patients symptoms. The underlying mechanism for the formation of these cysts is a chemically induced arachnoiditis

    Three men are presented, all of whom were born with difficulty and later developed severe syringomyelia with collapsing cords on air myelography. Each had hydrocephalus and a sizable subarachnoid pouch in the posterior fossa. The clinical features and investigations are presented with a discussion of the aetiology and possible mechanisms concerned in pathogenesis and treatment. All three men had posterior fossa exploration over fifty years after birth, and the first two were also treated by valved ventriculo-atrial shunts. Each patient has improved a little since operation, but no certainly that this was due to surgery has been proved in any case; none has progressed since the last operation.

    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.

    The aim of this study was to characterize amide proton transfer (APT)-weighted signals in acute and subacute haemorrhage brain lesions of various underlying aetiologies. Twenty-three patients with symptomatic haemorrhage brain lesions including tumorous (n = 16) and non-tumorous lesions (n = 7) were evaluated. APT imaging was performed and analyzed with magnetization transfer ratio asymmetry (MTR{sub asym}). Regions of interest were defined as the enhancing portion (when present), acute or subacute haemorrhage, and normal-appearing white matter based on anatomical MRI. MTR{sub asym} values were compared among groups and components using a linear mixed model. MTR{sub asym} values were 3.68 % in acute haemorrhage, 1.6 % in subacute haemorrhage, 2.65 % in the enhancing portion, and 0.38 % in normal white matter. According to the linear mixed model, the distribution of MTR{sub asym} values among components was not significantly different between tumour and non-tumour groups. MTR{sub asym} in acute haemorrhage was significantly higher than those in the other regions regardless of underlying pathology. Acute haemorrhages showed high MTR{sub asym} regardless of the underlying pathology, whereas subacute haemorrhages showed lower MTR{sub asym} than acute haemorrhages. These results can aid in the interpretation of APT imaging in haemorrhage brain lesions. (orig.)

    Full Text Available Background. There are several different causes for fetomaternal haemorrhage. Sinusoidal pattern, which is relatively characteristic for fetal anaemia, may in its final stages completely disappear. Differential diagnosis of silent trace of cardiotocogram with late decelerations is quite difficult to solve.Case report. A case of unusual injury of a pregnant woman is described. The injury led to fetomaternal haemorrhage. Typical sinusoidal pattern cardiotocogram was not seen and the differential diagnosis was hard to determine. Because of prompt intervention and efficient postnatal therapy the child and mother are both well. The dilemmas in regards to differential diagnosis are being discussed.Conclusions. It is important to be very careful in history taking even if the situation is urgent. If there is no explanation for pathological cardiotocogram, decision must be made according to pregnant woman’s wishes. Kleihauer-Betke test, which is easy to perform and gives much information, is described.

    To observe the clinical presentation of late haemorrhagic disease of the newborn (LHDNB), and clinical improvement after the administration of vitamin K/sub 1/. This is a prospective descriptive study. All the children older than seven days who presented with bleeding were admitted in pediatrics ward of Isra University Hyderabad from April 2006 to April 2007 were included. Data collection was done by means of detailed proforma. Analysis was done on SPSS version 11. Thirty five cases were included. Commonest site of bleeding was subcutaneous followed by oral and injection site. Mean age of late haemorrhagic disease of newborn was 109 days and minimum age of presentation was 28 days. Common clinical presentations were irritability, convulsions, poor reflexes and poor feeding. Mostly recovery was within 24 hours after vit K. Late HDN results in severe hemorrhage especially hemorrhage in the central nervous system. Administration of Vitamin K (1mg, 1M) at birth can present these severe complications. (author)

    Crimean-Congo haemorrhagic fever has been reported in more than 30 countries in Africa, Asia, the Middle East and Eastern Europe, with an increasing incidence in recent years, especially in Europe. Because no specific treatments have demonstrated efficacy, supportive treatment is essential, as well as the provision of a centre with the appropriate means to guarantee the safety of its healthcare professionals. Laboratory monitoring of thrombocytopenia, severe coagulopathy or liver failure is of critical importance. Patients with Crimean-Congo haemorrhagic fever should be admitted to High Level Isolation Units where appropriate biocontainment procedures can prevent nosocomial transmission through infected fluids or accidents with contaminated material. In case of high-risk exposures, early administration of ribavirin should be considered. Copyright © 2017. Publicado por Elsevier España, S.L.U.

    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.......

    Dengue is an endemic arboviral infection prevalent especially in tropical countries including Southern and Southeast Asia. Central Nervous System (CNS) involvement in dengue infection is uncommon. Haemorrhagic encephalitis is a rare presentation in dengue. This is a case of a 58-year-old male who presented with fever, petechial rash and altered sensorium. Dengue serology IgM was reactive and MRI brain was suggestive of haemorrhagic encephalitis. Patient was managed in Intensive Care Unit (ICU) but eventually succumbed to his illness. We report this fatal outcome of a common viral infection with unusual neurological presentation to propose an association between dengue and neurotropism and the need to look at dengue infection beyond its classical features.

    Full Text Available Abstract Background Transarterial embolisation (TAE is an effective method in control of haemorrhage irrespective of the nature of urological emergency. As the technique and technology have evolved, it is now possible to perform highly selective embolisation. The aim of this study was to critically appraise feasibility and efficacy of therapeutic TAE in control of haemorrhagic urological emergencies using selective and non-selective embolisation. Specifically, we aimed to assess the impact of timing of embolisation on the requirement of blood transfusion and long-term morphological and functional follow-up of embolised organs. Methods This is a single institutional observational study carried out between March 1992 and March 2006. Records of all patients who underwent selective and non-selective angioembolisation to control bleeding in urological emergencies were reviewed. Data on success rate, periprocedural complications, timing of embolisation, requirement of blood transfusion and the long-term morphological and functional outcomes of embolised organs was recorded. Results Fourteen patients underwent endovascular control of bleeding as a result of trauma, iatrogenic injury and spontaneous perinephric haemorrhage during a period of 14 years. All these patients would have required emergency open surgery without the option of embolisation procedure. The mean time between the first presentation and embolisation was 22 hours (range 30 minutes to 60 hours. Mean pre-embolisation transfusion requirement was 6.8 units (range 0–22 units. None of the patients with successful embolisation required post-procedural blood transfusion. Permanent haemostasis was achieved in all but one patient, who required emergency nephrectomy. There were no serious procedure related post-embolisation complications. Conclusion Endovascular control using transarterial angioembolisation is an effective method for managing haematuria or haemorrhage in urological emergencies

    2011-05-01

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

    The aim of the study was to compare the effectiveness of Carbetocin versus Oxyotcin during caesarean section for preventing postpartum haemorrhage. Prospective observational study (before/after design). Five hundred and forty patients who received an injection of Oxytocin were compared to 262 patients with single injection of 100 micrograms of Carbetocin. The primary outcome was to compare the differential hematocrit level between pre- and postoperative blood samples. The secondary outcome was to compare differential hemoglobin level and the use of complementary therapies for postpartum haemorrhage. We did not find any difference between the Oxytocin and Carbetocin groups on differential hematocrit level. There was no difference between the groups regarding the use of additionnal therapies (Sulproston injections, blood transfusions and surgery methods). The rate of postpartum haemorrhage was similar in the two groups (18.7% vs 21.6%; P=0.33). We found a lower percentage of patients with differential of hemoglobin level between 2 g/dL and 4 g/dL in the Carbetocin group (6.5% vs 15.6%, Poxytocin. Carbetocin seems to reduce the need for postoperative intravenous iron injection. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    In the management of subarachnoid hemorrhage (SAH), the potential for early complications and the centralization of limited resources often challenge the delivery of timely neurosurgical care. We sought to determine the impact of proximity to the accepting neurosurgical centre on outcomes following aneurysmal SAH. Using administrative data, we analyzed patients undergoing treatment for aneurysmal subarachnoid hemorrhage at neurosurgical centres in Ontario between 1995 and 2004. We compared mortality for patients receiving treatment at a centre in their county (in-county) versus those treated from outside counties (out-of-county). We also examined the impact of distance from the patient's residence to the treating centre. The mortality rates were significantly lower for in-county versus out-of-county patients (23.5% vs. 27.6%, p=0.009). This advantage remained significant after adjusting for potential confounders (HR=0.84, p=0.01). The relationship between distance from the treating centre and mortality was biphasic. Under 300 km, mortality increased with increasing distance. Over 300 km, a survival benefit was observed. Proximity to the treating neurosurgical centre impacts survival after aneurysmal SAH. These results have significant implications for the triage of these critically ill patients.

    Full Text Available Cerebral vasospasm is a well-known consequence of aneurysmal subarachnoid hemorrhage (SAH triggered by blood breakdown products. Here, we present the first case of cerebral vasospasm with ischemia following a spontaneous spinal SAH. A 67-year-old woman, who was on Coumadin for atrial fibrillation, presented with chest pain radiating to the back accompanied by headache and leg paresthesias. The international normalized ratio (INR was 4.5. Ten hours after presentation, she developed loss of movement in both legs and lack of sensation below the umbilicus. Spine MRI showed intradural hemorrhage. Her coagulopathy was reversed, and she underwent T2 to T12 laminectomies. A large subarachnoid hematoma was evacuated. Given her complaint of headache preoperatively and the intraoperative finding of spinal SAH, a head CT was done postoperatively that displayed SAH in peripheral sulci. On postoperative day 5, she became obtunded. Brain MRI demonstrated focal restricted diffusion in the left frontoparietal area. Formal angiography revealed vasospasm in anterior cerebral arteries bilaterally and right middle cerebral artery. Vasospasm was treated, and she returned to baseline within 48 hours. Spontaneous spinal SAH can result in the same sequelae typically associated with aneurysmal SAH, and the clinician must have a degree of suspicion in such patients. The pathophysiological mechanisms underlying cerebral vasospasm may explain this unique case.

    Bilateral cystic adrenal tumours are a rare presentation of neuroblastoma. Intratumoural haemorrhage is a frequent finding in neuroblastoma, but is rarely symptomatic. We present an 11-month-old girl with predominantly cystic bilateral neuroblastomas and distant lymph-node metastasis. Massive intracystic haemorrhage and superior vena cava (SVC) syndrome were ominous prognostic factors, leading to death. Large tumours with intracystic haemorrhage might require a conservative approach. (orig.)

    Objective: To discuss the effect and safety of transcatheter angiographic embolization (TAE)for managing massive obstetric haemorrhage. Methods: 17 cases of obstetric massive haemorrhage or with haemorrhage tendency were treated with TAE. Among them 14 cases had haemorrhage already, including 10 cases after abortion, caesarean section or normal labor and other 4 of hydatidiform mole. 3 cases with obstetric haemorrhage tendency included 2 cases of placenta praevia and 1 case of cervical pregnancy. Selective catheterization into bilateral uterine arteries or internal iliac arteries for DSA, showed the cause and location of the haemorrhage and then embolized with gelfoam sponge chips (1-3 mm) or Polyvinyl Alcohol(PVA); and part of the cases with MTX through uterine arterial perfusion. Results: The successful rate of catheterization was 100%. The achievement in 14 cases showed no active haemorrhage immediately after the procedure and no vaginal bleeding after 1-5 days. In 3 prophylactic cases before abortion or uterine curettage, obstetric massive haemorrhage occurred in 1 case, but not so in other 2 cases. Conclusions: TAE is an effective treatment for obstetric massive haemorrhage, with the advantages of minimal trauma, fast and definite treating effect and less complications. Prophylactical application for high risk patients can reduce the bleeding and mortality. (authors)

    Background Although cervical pain is widespread, most victims are only mildly and occasionally affected. A minority, however, suffer chronic pain and/or functional impairments. Although there is abundant literature regarding nontraumatic neck pain, little focuses on diagnostic criteria. During the last decade, research on neck pain has been designed to evaluate underlying pathophysiological mechanisms, without noteworthy success. Independent researchers have investigated postural balance and cervicocephalic kinesthetic sensibility among patients with chronic neck pain, and have (in most cases) concluded the source of the problem is a reduced ability in the neck's proprioceptive system. Here, we investigated cervicocephalic kinesthetic sensibility and postural balance among patients with nontraumatic chronic neck pain. Methods Ours was a two-group, observational pilot study of patients with complaints of continuous neck pain during the 3 months prior to recruitment. Thirteen patients with chronic neck pain of nontraumatic origin were recruited from an institutional outpatient clinic. Sixteen healthy persons were recruited as a control group. Cervicocephalic kinesthetic sensibility was assessed by exploring head repositioning accuracy and postural balance was measured with computerized static posturography. Results Parameters of cervicocephalic kinesthetic sensibility were not reduced. However, in one of six test movements (flexion), global repositioning errors were significantly larger in the experimental group than in the control group (p < .05). Measurements did not demonstrate any general impaired postural balance, and varied substantially among participants in both groups. Conclusion In patients with nontraumatic chronic neck pain, we found statistically significant global repositioning errors in only one of six test movements. In this cohort, we found no evidence of impaired postural balance. Head repositioning accuracy and computerized static posturography are

    Complex regional pain syndrome (CRPS) is usually associated with trauma. Rarely, it may be seen in association with malignancies. We present here the bone scan and X-ray findings in the case of a 56-year-male-patient with adenocarcinoma lung who also had non-traumatic CRPS without involvement of the stellate ganglion. The case highlights the fact that spontaneous development of reflex sympathetic dystrophy may be associated with a neoplastic etiology. (author)

    Full Text Available Decrease in bone mineral density of metaphysis in patients with nontraumatic avascular necrosis of the femoral head (AVN is considered the main factor leading to aseptic loosening of the femoral component. Researchers have hypothesized that a cementless, anatomic stem fixed proximally to the metaphysis has a higher risk for aseptic loosening than a straight stem that is fixed at the diaphysis in patients with nontraumatic AVN. The purpose of the current study was to evaluate the effects of cancellous bone stiffness at the metaphysis and stem geometry on the micromotion of the femoral stem relative to the femur. The VerSys (straight and ABG (anatomic femoral stems were enrolled in this finite element study to determine the performance of prosthetic micromotion. The simulated load to the hip joint during heel strike was assigned. Results showed that the VerSys model represented better resistance in micromotion between the bone/stem interface than the ABG model in either normal or poor cancellous bone stiffness at the metaphysis. The bone quality at the metaphysis of patients with nontraumatic AVN should be considered prior to selecting a femoral stem. In consideration of initial stability, acementless, straight stem that fits the isthmus is more favourable than an anatomic stem that is fixed to the proximal area of the canal.

    Hospital Emergency Departments (ED) provide a variety of medical care, some of which is for non-urgent, chronic conditions. We describe the statewide use of hospital ED for selected non-traumatic dental conditions that occurred during 2001-2008 in New Hampshire. Using the administrative hospital discharge dataset for 2001-2007, and provisional 2008 data, we identified all visits for selected dental conditions and calculated age-adjusted rates per 10,000 New Hampshire residents by several socio-demographic characteristics. The Spearman correlation coefficient was used to assess the statistical significance for trend over time. Emergency department visits for non-traumatic dental conditions increased significantly from 11,067 in 2001 to 16,238 visits in 2007 (P dental care users. The most frequent dental complains (46%) were diseases of the teeth and supporting structures, diagnostic code ICD-9-CM-525. Dental care associated ED visits have increased in New Hampshire. Individuals seeking dental treatment in ED are not receiving definitive treatment, and they misuse limited resources. Future studies need to determine the specific barriers to timely and effective dental care in dental offices. Ongoing consistent monitoring of ED use for non-traumatic dental conditions is essential.

    Full Text Available Abstract Background The aim of the study was to explore resilience among refugee children whose parents had been traumatized and were suffering from Post-Traumatic Stress Disorder (PTSD. Methods The study comprised 80 refugee children (40 boys and 40 girls, age range 6–17 yrs, divided into two groups. The test group consisted of 40 refugee children whose parents had been tortured in Iraq before coming to Sweden. In accordance with DSM-IV criteria, these children were further divided in two sub-groups, those who were assessed as having PTSD-related symptoms (n = 31 and those who did not have PTSD-related symptoms (n = 9. The comparison group consisted of 40 children from Egypt, Syria and Morocco whose parents had not been tortured. Wechsler Intelligence Scale for Children, 3rd edn. (WISC-III, Diagnostic Interview for Children and Adolescents- Revised (DICA-R, Post-Traumatic Stress Symptoms checklist (PTSS, "I Think I am" (ITIA and Strengths and Difficulties Questionnaire (SDQ were used to assess IQ; PTSD-related symptoms; self-esteem; possible resilience and vulnerability. Results Children without PTSD/PTSS in the traumatized parents group had more favorable values (ITIA and SDQ with respect to total scores, emotionality, relation to family, peer relations and prosocial behavior than the children in the same group with PTSD/PTSS and these values were similar to those the children in the comparison group (the non-traumatized parents group. The children in the non-traumatized parents group scored significantly higher on the IQ test than the children with traumatized parents, both the children with PTSD-related symptoms and those without PTSD-related symptoms. Conclusion Adequate emotional expression, supportive family relations, good peer relations, and prosociality constituted the main indicators of resilience. Further investigation is needed to explore the possible effects of these factors and the effects of IQ. The findings of this study are

    Progranulin has been reported to have neuroprotective actions in cultured neurons. This study investigated the effect of recombinant rat progranulin on early brain injury after subarachnoid hemorrhage. Controlled in vivo laboratory study. Animal research laboratory. Two hundred thirty adult male Sprague-Dawley rats weighing 280-320 g. Subarachnoid hemorrhage was induced in rats by endovascular perforation. Rat recombinant progranulin (1 and 3 ng) was administrated intracerebroventricularly at 1.5 hours after subarachnoid hemorrhage. Progranulin small interfering RNA was administrated by intracerebroventricularly at 1 day before subarachnoid hemorrhage induction. Subarachnoid hemorrhage grade, neurologic score, and brain water content were measured at 24 and 72 hours after subarachnoid hemorrhage. Neural apoptosis was evaluated by double immunofluorescence staining using terminal deoxynucleotidyl transferase-mediated uridine 5'-triphosphate-biotin nick-end labeling and neuronal nuclei. For mechanistic study, the expression of progranulin, phosphorylated Akt, Akt, p-Erk, Erk, Bcl-2, and cleaved caspase-3 were analyzed by Western blot at 24 hours after subarachnoid hemorrhage. siRNA for sortilin 1 (a progranulin receptor) was used to intervene the downstream pathway. The expression of progranulin decreased and reached the lowest point at 24 hours after subarachnoid hemorrhage. Administration of rat recombinant progranulin decreased brain water content and improved neurologic functions at both 24 and 72 hours after subarachnoid hemorrhage, while knockdown of endogenous progranulin aggravated neurologic deficits after subarachnoid hemorrhage. Rat recombinant progranulin treatment reduced neuronal apoptosis, while progranulin deficiency promoted neuronal apoptosis at 24 hours after subarachnoid hemorrhage. Rat recombinant progranulin promoted Akt activation, increased Bcl-2 level, but reduced caspase-3 level. Knockdown of progranulin binding factor sortilin 1

    Haemorrhagic diathesis is one of the dominant symptoms of acute post-irradiation lesion. Haemorrhagic syndrome is caused by the disturbance of haemocoagulation during simultaneous lesion of the vascular system. In our study we have tried to affect the post-irradiation haemocoagulation disturbance. Epsilon- amino-caproic acid (EACA) administered between the 8{sup th} and the 18{sup th} day (0.4 g/kg per day) to whole- body irradiated dogs (600 R) partially regulated the post-irradiation disturbance of haemocoagulation. The favourable effect of EACA was verified by in vitro experiments in which the blood of irradiated dogs was used. A repeated administration of EACA in the dose of 0.4 g/kg per day to whole-body irradiated rats (600 R) did not substantially affect the post-irradiation changes in the number of white blood elements; however, its administration to healthy animals caused lymphocytosis. In whole-body irradiated dogs (600 R) we have found lower levels of EACA in the blood up to the 8 day following irradiation as compared with healthy dogs after oral application of EACA. The whole-body irradiation of mice did not increase the acute toxicity of EACA. The daily administration of 0.4 g EACA/kg to whole-body irradiated mice (600 and 700 R) did not change the mortality induced by irradiation. The authors consider EACA to be a suitable compound for a complex therapy of radiation sickness. The administration of para-amino-methyl-benzoic acid (PAMBA), in spite of a certain improvement of postirradiation haemocoagulation disturbance, is less efficient. Our recent experiments with ellagic acid which significantly affects the post-traumatic haemorrhage in whole-body irradiated rats seem to be very promising. (author)

    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. Copyright © 2015 Asociación Argentina de Microbiología.

    Full Text Available Hydrocephalus (HCP is a common complication in patients with subarachnoid hemorrhage. In this review, we summarize the advanced research on HCP and discuss the understanding of the molecular originators of HCP and the development of diagnoses and remedies of HCP after SAH. It has been reported that inflammation, apoptosis, autophagy, and oxidative stress are the important causes of HCP, and well-known molecules including transforming growth factor, matrix metalloproteinases, and iron terminally lead to fibrosis and blockage of HCP. Potential medicines for HCP are still in preclinical status, and surgery is the most prevalent and efficient therapy, despite respective risks of different surgical methods, including lamina terminalis fenestration, ventricle-peritoneal shunting, and lumbar-peritoneal shunting. HCP remains an ailment that cannot be ignored and even with various solutions the medical community is still trying to understand and settle why and how it develops and accordingly improve the prognosis of these patients with HCP.

  9. Prevention of postpartum haemorrhage with the oxytocin analogue carbetocin.

    Postpartum haemorrhage is the leading cause of maternal mortality worldwide: 67-80% of cases are caused by uterine atony. Preventive measures include prophylactic drug use to aid uterine contraction after delivery, thus avoiding severe blood loss and reducing maternal morbidity and mortality. Carbetocin is a synthetic analogue of oxytocin with a half-life approximately 4-10 times longer than that reported for oxytocin. It combines the safety and tolerability profile of oxytocin with the sustained uterotonic activity of injectable ergot alkaloids. Furthermore, carbetocin can be administered as a single dose injection either intravenously or intramuscularly rather than as an infusion over several hours as is the case with oxytocin. Carbetocin is currently indicated for prevention of uterine atony after delivery by caesarean section in spinal or epidural anaesthesia. Data from three randomised controlled trials in caesarean delivery and a meta-analysis indicate that carbetocin significantly reduces the need for additional uterotonic agents or uterine massage to prevent excessive bleeding compared with placebo or oxytocin. The risk of headache, tremor, hypotension, flushing, nausea, abdominal pain, pruritus and feeling of warmth was similar in women who received carbetocin or oxytocin. The findings from two more recent double-blind randomised trials and one retrospective study suggest that carbetocin may also represent a good alternative to conventional uterotonic agents for prevention of postpartum haemorrhage after vaginal deliveries. A reduced need for additional uterotonics was observed with carbetocin vs. oxytocin in high-risk women and carbetocin was at least as effective as syntometrine in low-risk women. In these studies of vaginal deliveries, carbetocin was associated with a low incidence of adverse effects and demonstrated a better tolerability profile than syntometrine. Carbetocin had a long duration of action compared with intravenous oxytocin alone and a

    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

    Early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (aSAH) is defined as brain injury occurring within 72 h of aneurysmal rupture. Although EBI is the most significant predictor of outcomes after aSAH, its underlying pathophysiology is not well understood. We hypothesize that EBI after aSAH is associated with an increase in peripheral inflammation measured by cytokine expression levels and changes in associations between cytokines. aSAH patients were enrolled into a prospective observational study and were assessed for markers of EBI: global cerebral edema (GCE), subarachnoid hemorrhage early brain edema score (SEBES), and Hunt-Hess grade. Serum samples collected at ≤ 48 h of admission were analyzed using multiplex bead-based assays to determine levels of 13 pro- and anti-inflammatory cytokines. Pairwise correlation coefficients between cytokines were represented as networks. Cytokine levels and differences in correlation networks were compared between EBI groups. Of the 71 patients enrolled in the study, 17 (24%) subjects had GCE, 31 (44%) subjects had SEBES ≥ 3, and 21 (29%) had HH ≥ 4. IL-6 was elevated in groups with GCE, SEBES ≥ 3, and HH ≥ 4. MIP1β was independently associated with high-grade SEBES. Correlation network analysis suggests higher systematic inflammation in subjects with SEBES ≥ 3. EBI after SAH is associated with increased levels of specific cytokines. Peripheral levels of IL-10, IL-6, and MIP1β may be important markers of EBI. Investigating systematic correlations in addition to expression levels of individual cytokines may offer deeper insight into the underlying mechanisms related to EBI.

    Full Text Available Introduction: Posterior urethral strictures after prostatic radiotherapy or surgery for benign prostatic hyperplasia (BPH refractory to minimal invasive procedures (dilation and/or endoscopic urethrotomy are challenging to treat. Published reports of alternative curative management are extremely rare. This is a preliminary report on the treatment of these difficult strictures by urethroplasty. Materials and Methods: Seven cases were treated: 4 cases occurred after open prostatectomy or transurethral resection of the prostate for BPH, one case after external beam irradiation and 2 after brachytherapy. The 4 cases after BPH-related surgery were in fact complete obstructions at the bladder neck and the membranous urethra with the prostatic urethra still partially patent. Anastomotic repair by perineal route was done in all cases with bladder neck incision in the BPH-cases and prostatic apex resection in the radiotherapy cases. Results: Mean follow-up was 31 months (range: 12-72 months. The operation was successful, with preserved continence, in 3 of the 4 BPH-cases and in 2 of the 3 radiotherapy cases. An endoscopic incision was able to treat a short re-stricture in the BPH-patient and a longer stricture at the bulbar urethra could be managed with a perineostomy in the radiotherapy-patient. Conclusion: Posterior non-traumatic strictures refractory to minimal invasive procedures (dilation/endoscopic urethrotomy can be treated by urethroplasty using an anastomotic repair with a bladder neck incision if necessary.

    Full Text Available Introduction. Spontaneous nontraumatic pneumocephalus (PNC and cerebrospinal fluid (CSF leaks are both very uncommon conditions. We report a rare case of spontaneous pneumocephalus associated with CSF leak secondary to right sphenoid sinus bony defect without history of trauma. Case Description. 51-year-old Hispanic female with past medical history of hypertension and idiopathic intracranial hypertension (Pseudotumor Cerebri presented to the emergency room complaining of headache and clear discharge from the right nostril. Physical examination was significant for right frontal sinus tenderness and clear discharge from right nostril. Computed Tomography (CT scan of the brain showed moderate amount of extra-axial air within the right cerebral hemisphere indicative of pneumocephalus. CT scan of facial bones showed bony defect along the right sphenoid sinus with abnormal CSF collection. The patient was started on intravenous antibiotics for meningitis prophylaxis and subsequently underwent transsphenoidal repair of cerebrospinal fluid leak with abdominal fat graft. CSF rhinorrhea stopped completely after the surgery with near complete resolution of pneumocephalus before discharge. Conclusions. Early identification of pneumocephalus and surgical intervention can help decrease the morbidity and avoid possible complications. Idiopathic intracranial hypertension, although rare, can lead to CSF leak and pneumocepahlus.

    The aim of this retrospective study was to evaluate factors potentially influencing short- and long-term mortality in patients who had a non-traumatic lower limb amputation in a university hospital. A consecutive series of 93 amputations (16% toe/foot, 33% trans-tibial, 9% through knee and 42......% trans-femoral) were studied. Their mean age was 75.8 years; 21 (23%) were admitted from a nursing home and 87 (92%) were amputated due to a vascular disease and/or diabetes. Thirty days and 1-year mortality were 30 and 54%, respectively. Cox regression analysis demonstrated that the 30-day mortality...... was associated with older age (P = 0.01), and the number of co-morbidities (P = 0.04), when adjusted for gender, previous amputations, cause of and amputation level, and residential status. Thus, a patient with 4 or 5 co-morbidities (n = 20) was seven times more likely to die within 30 days, compared...

    Tissue injury is accompanied by pain and results in increased energy expenditure, which may promote catabolism. The extent to which pain contributes to this sequence of events is not known. In a cross-over design, 10 healthy volunteers were examined on three occasions; first, during self-controlled nontraumatic electrical painful stimulus to the abdominal skin, maintaining an intensity of 8 on the visual analogue scale (0-10). Next, the electrical stimulus was reproduced during local analgesia and, finally, there was a control session without stimulus. Indirect calorimetry and blood and urine sampling was done in order to calculate energy expenditure and substrate utilization. During pain stimulus, energy expenditure increased acutely and reversibly by 62% (95% confidence interval, 43-83), which was abolished by local analgesia. Energy expenditure paralleled both heart rate and blood catecholamine levels. The energy expenditure increase was fuelled by all energy sources, with the largest increase in glucose utilization. The pain-related increase in energy expenditure was possibly mediated by adrenergic activity and was probably to a large extent due to increased muscle tone. These effects may be enhanced by cortical events related to the pain. The increase in glucose consumption favours catabolism. Our findings emphasize the clinical importance of pain management.

    The non-traumatic spinal epidural hematoma (NTSEH) is a rare entity that can be the cause of an acute spinal compression syndrome. the objective of this review is to identify the characteristics by MRI and NTSEH and to analyze the factors that influence in its prognosis. In the years 1994 and 1999, 12 patients with NTSEH have been diagnosed in our hospital, and a MRI was performed during the acute phase. the characteristics of the lesions have been analyzed by MRI, with special emphasis on the topographic data and resonance signal and the factors that can influence in the clinical prognosis of the patients. Initially, all of the patients presented pain in the cervical dorsal or interscapular site, followed by a sensitive-motor deficit picture. The MRI showed a lesion of expansive character and posterior epidural location in every case that would produce varying degrees of compression on the spinal cord. The NTSEH should be considered as one of the causes of acute spinal cord compression. The clinical association of intense cervical, dorsal or interscapular pain followed by a sensomotor deficit picture should lead to the suspicion of this entity, that would require an immediate examination with MRI to verify its diagnosis. Both the clinical manifestations as well as the characteristics observed by MRI of the NTSEH have a prognostic value and determine the therapeutic decision. (Author) 34 refs

    Cerebellar haemorrhage accounts for 5-10% of all intracerebral haemorrhages and leads to severe, long-lasting functional deficits. Currently, there is limited research on this stroke subtype, which may be due to the lack of a suitable composite neuroscoring system specific for cerebellar injury in rodents. The purpose of this study is to develop a comprehensive composite neuroscore test for cerebellar injury using a rat model of cerebellar haemorrhage. Sixty male Sprague-Dawley rats were subjected to either sham surgery or cerebellar haemorrhage. Twenty-four hours post-injury, neurological behaviour was evaluated using 17 cost-effective and easy-to-perform tests, and a composite neuroscore was developed. The composite neuroscore was then used to assess functional recovery over seven days after cerebellar haemorrhage. Differences in the composite neuroscore deficits for the mild and moderate cerebellar haemorrhage models were observed for up to five days post-ictus. Until now, a composite neuroscore for cerebellar injury was not available for rodent studies. Herein, using mild and moderate cerebellar haemorrhage rat models a composite neuroscore for cerebellar injury was developed and used to assess functional deficits after cerebellar haemorrhage. This composite neuroscore may also be useful for other cerebellar injury models.

    Intracerebral haemorrhage still causes considerable disability and mortality. The studies on conservative and operative management are inconclusive, probably due to inexact volumetry of the haemorrhage. We investigated whether three-dimensional (3-D), voxel-based volumetry of the haemorrhage and its mass effect is feasible with routine computed tomography (CT) scans. The volumes of the haemorrhage, ventricles, midline shift, the intracranial volume and ventricular compression in CT scans of 12 patients with basal ganglia haemorrhage were determined with the 3-D slicer software. Indices of haemorrhage and intracranial or ventricular volume were calculated and correlated with the clinical data. The intended measures could be determined with an acceptable intra-individual variability. The 3-D volumetric data tended to correlate better with the clinical course than the conventionally assessed distance of midline shift and volume of haemorrhage. 3-D volumetry of intracranial haemorrhage and its mass effect is feasible with routine CT examination. Prospective studies should assess its value for clinical studies on intracranial space-occupying diseases. (orig.)

    More than one third of patients with subarachnoid hemorrhage (SAH) develop clinically significant vasospasm, as a leading morbidity and mortality factor for these patients. It is widely accepted that a) Degradation products of blood are the causative factors of vasospasm b) The amount of subarachnoid blood seen on admission CT is correlated to the risk of vasospasm c) Reducing the subarachnoid clot burden at the time of surgery reduces the risk of vasospasm. But there is no existing method to clear the blood from subarachnoid spaces satisfactorily. We have evaluated safety and feasibility of fluid exchange catheter system in SAH, to achieve this goal. We were successful in clearing cisternal blood in three patients with aneurysmal rupture with fluid exchange catheter system. Baseline CT scan of brain was performed immediately after the surgery and then at the end of irrigation. The amount of subarachnoid blood was evaluated. This innovative, fluid exchange catheter system infuses and aspirates micro volumes of drug solution in a cyclic mode, ensuring isobaric exchange of fluids. The result is good clearance of blood in subarachnoid spaces were seen in all the patients. Also, significant improvement in neurological deficits secondary to vasospasm was seen. We conclude that the fluid exchange catheter system is safe and adoptable in neurosurgical practice.

    No prospective studies including large numbers of dogs with acute haemorrhagic diarrhoea syndrome (AHDS) are published so far. The aim of this case-control study was to describe signalment, history, clinical signs, laboratory values and course of disease in dogs with AHDS. Dogs (108) with idiopathic acute haemorrhagic diarrhoea (schnauzer and Maltese. The syndrome was more likely to occur during winter. Vomiting preceded the onset of bloody diarrhoea in 80 per cent of dogs and haematemesis was observed in half of those cases. Median AHDS index at presentation was 12 (range 3-17). Haematocrit was generally high (median 57.1 per cent; range 33-76 per cent), but exceeded 60 per cent only in 31.4 per cent of dogs. Haematocrit of 48.1 per cent of dogs was above reference range, as was monocyte (50.0 per cent), segmented (59.6 per cent) and band neutrophil count (45.2 per cent). A rapid clinical improvement occurred during the first 48 hours. British Veterinary Association.

    Canine circovirus (CanineCV) has been detected in some dogs with severe haemorrhagic diarrhoea, but its pathogenic role is unclear. This study evaluated a suspected association between the presence of CanineCV and acute haemorrhagic diarrhoea syndrome (AHDS) in dogs. The prevalence of CanineCV in dogs with AHDS was compared with that in healthy dogs and those infected with canine parvovirus (CPV). Additionally, time to recovery and mortality rate were compared between CanineCV-positive and CanineCV-negative dogs. Faecal samples of dogs with AHDS (n=55), healthy dogs (n=66) and dogs infected with CPV (n=54) were examined by two real-time TaqMan PCR assays targeting the replicase and capsid genes of CanineCV. CanineCV was detected in faecal samples of two dogs with AHDS, three healthy controls and seven dogs infected with CPV. Among the three groups, there was no significant difference in prevalence of CanineCV. CPV-infected animals that were coinfected with CanineCV had a significantly higher mortality rate compared with those negative for CanineCV. CanineCV does not appear to be the primary causative agent of AHDS in dogs, but might play a role as a negative co-factor in disease outcome in dogs with CPV infection.

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

    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...

    Multifaceted: extensive discussions at workshop and conference presentations, survey of experts and feedback. Present the background, purpose and development of the International Spinal Cord Injury (SCI) Data Sets for Non-Traumatic SCI (NTSCI), including a hierarchical classification of aetiology. International. Consultation via e-mail, presentations and discussions at ISCoS conferences (2006-2009), and workshop (1 September 2008). The consultation processes aimed to: (1) clarify aspects of the classification structure, (2) determine placement of certain aetiologies and identify important missing causes of NTSCI and (3) resolve coding issues and refine definitions. Every effort was made to consider feedback and suggestions from participants. The International Data Sets for NTSCI includes basic and an extended versions. The extended data set includes a two-axis classification system for the causes of NTSCI. Axis 1 consists of a five-level, two-tier (congenital-genetic and acquired) hierarchy that allows for increasing detail to specify the aetiology. Axis 2 uses the International Statistical Classification of Diseases (ICD) and Related Health Problems for coding the initiating diseases(s) that may have triggered the events that resulted in the axis 1 diagnosis, where appropriate. Additional items cover the timeframe of onset of NTSCI symptoms and presence of iatrogenicity. Complete instructions for data collection, data sheet and training cases are available at the websites of ISCoS (http://www.iscos.org.uk) and ASIA (http://www.asia-spinalinjury.org). The data sets should facilitate comparative research involving NTSCI participants, especially epidemiological studies and prevention projects. Further work is anticipated to refine the data sets, particularly regarding iatrogenicity.

    Non-traumatic coma (NTC) is a serious condition requiring swift medical or surgical decision making upon arrival at the emergency department. Knowledge of the most frequent etiologies of NTC and associated mortality might improve the management of these patients. Here, we present the results of a systematic literature search on the etiologies and prognosis of NTC. Two reviewers independently performed a systematic literature search in the Pubmed, Embase and Cochrane databases with subsequent reference and citation checking. Inclusion criteria were retrospective or prospective observational studies on NTC, which reported on etiologies and prognostic information of patients admitted to the emergency department or intensive care unit. Eventually, 14 studies with enough data on NTC, were selected for this systematic literature review. The most common causes of NTC were stroke (6-54%), post-anoxic coma (3-42%), poisoning (coma (54-89%) and lowest for poisoning (0-39%) and epilepsy (0-10%). NTC represents a challenge to the emergency and the critical care physicians with an important mortality and moderate-severe disability rate. Even though, included studies were very heterogeneous, the most common causes of NTC are stroke, post anoxic, poisoning and various metabolic etiologies. The best outcome is achieved for patients with poisoning and epilepsy, while the worst outcome was seen in patients with stroke and post-anoxic coma. Adequate knowledge of the most common causes of NTC and prioritizing the causes by mortality ensures a swift and adequate work-up in diagnosis of NTC and may improve outcome.

    Literature review. Globally map non-traumatic spinal cord injury (NTSCI) incidence, prevalence, survival, level of injury and aetiology. Propose a research framework for NTSCI prevention and launch a repository of NTSCI data. Initiative of the International Spinal Cord Society Prevention Committee. Literature search of Medline and Embase (1959-June 2011). Relevant articles in any language regarding adults with NTSCI were included. Stratification of information about incidence and prevalence into green/yellow/orange/red data quality 'zones' and comparisons between World Health Organisation (WHO) regions and countries. Three hundred and seventy-seven abstracts reviewed--45 of these from 24 countries in 12 of the 21 WHO global regions had relevant information. Only one publication had survival data. Prevalence data for NTSCI existed for only two countries, India (prevalence of 2,310/million population, Kashmir region) and Canada (prevalence of 1,120/million population). The incidence rates for WHO regions were: Asia Pacific, high income 20/million population/year; Australasia (26/million population/year); Western Europe median of 6/million population/year; North America, high income median 76/million population/year (based on poor-quality studies); and Oceania 9/million population/year. Developed countries tended to have a higher proportion of cases with degenerative conditions and tumours. Developing countries, in comparison, tended to have a higher proportion of infections, particularly tuberculosis and HIV, although a number also reported tumours as a major cause. Insufficient survival, prevalence and incidence data are a predominant finding of this review. The piecemeal approach to epidemiological reporting of NTSCI, particularly failing to include sound regional population denominators, has exhausted its utility. Minimum data collection standards are required.

    2006-01-01

    The risk of developing bilateral disease progressing to total hip arthroplasty (THA) among patients who undergo unilateral THA for non-traumatic avascular necrosis (AVN) remains poorly understood. An analysis of the time-course to contralateral THA, as well as the effects of underlying AVN risk factors, is presented. Forty-seven consecutive patients who underwent THA for AVN were evaluated. Peri-operative and annual post-operative antero-posterior pelvis radiographs were examined for evidence of contralateral involvement. Patient age, weight, height, underlying AVN risk factor(s), date of onset of contralateral hip pain if occurred, and date of contralateral THA if performed, were recorded. Bone scan, computerized tomography and magnetic resonance imaging data were utilized when available. Twenty-one patients (46.6%) underwent contralateral THA for AVN within a median of 9 months after the initial THA (range 0-93, interquartile range 28.5 months). The median follow-up for patients without contralateral THA was 75 months (range 3-109, interquartile range 69 months). Thirty-four patients had radiographic findings of contralateral AVN at study entry; 25 were symptomatic bilaterally at entry and 7 developed contralateral symptoms within a mean time of 12 months (median 10 months, interquartile range 12 months). None of the 13 patients who were free of radiographic evidence of contralateral AVN at study entry developed evidence of AVN during the follow-up. AVN associated with glucocorticoid use was more likely to manifest as bilateral disease than either idiopathic AVN or ethanol-associated AVN (P=0.02 and P=0.03 respectively). Radiographically-evident AVN in the contralateral hip at THA is unlikely to remain asymptomatic for a prolonged period of time. Conversely, asymptomatic contralateral hips without radiographic evidence of AVN are unlikely to develop clinically significant AVN.

  13. Nontraumatic hypotension and shock in the emergency department and the prehospital setting, prevalence, etiology, and mortality: a systematic review.

    Full Text Available Acute patients presenting with hypotension in the prehospital or emergency department (ED setting are in need of focused management and knowledge of the epidemiology characteristics might help the clinician. The aim of this review was to address prevalence, etiology and mortality of nontraumatic hypotension (SBP ≤ 90 mmHg with or without the presence of shock in the prehospital and ED setting.We performed a systematic literature search up to August 2013, using Medline, Embase, Cinahl, Dare and The Cochrane Library. The analysis and eligibility criteria were documented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-guidelines and The Cochrane Collaboration. No restrictions on language, publication date, or status were imposed. We used the Newcastle-Ottawa quality assessment scale (NOS-scale and the Strengthening the Reporting of Observational studies in Epidemiology (STROBE-statement to assess the quality.Six observational studies were considered eligible for analysis based on the evaluation of 11,880 identified papers. Prehospital prevalence of hypotension was 19.5/1000 emergency medicine service (EMS contacts, and the prevalence of hypotensive shock was 9.5-19/1000 EMS contacts with an inhospital mortality of shock between 33 to 52%. ED prevalence of hypotension was 4-13/1000 contacts with a mortality of 12%. Information on mortality, prevalence and etiology of shock in the ED was limited. A meta-analysis was not feasible due to substantial heterogeneity between studies.There is inadequate evidence to establish concise estimates of the characteristics of nontraumatic hypotension and shock in the ED or in the prehospital setting. The available studies suggest that 2% of EMS contacts present with nontraumatic hypotension while 1-2% present with shock. The inhospital mortality of prehospital shock is 33-52%. Prevalence of hypotension in the ED is 1% with an inhospital mortality of 12%. Prevalence

    To compare standing head posture measurements between patients with nontraumatic neck pain (NP) and pain-free individuals. Single-blind (assessor) cross-sectional study. Hospital and general community. Consecutive patients (n=40) with chronic nontraumatic NP and age- and sex-matched pain-free participants (n=40). Not applicable. Three angular measurements: the angle between C7, the tragus of the ear, and the horizontal; the angle between the tragus of the ear, the eye, and the horizontal; and the angle between the inferior margins of the right and the left ear and the horizontal were calculated through the digitization of video images. NP patients were found to have a significantly smaller angle between C7, the tragus, and the horizontal, resulting in a more forward head posture than pain-free participants (NP, mean +/- SD, 45.4 degrees +/-6.8 degrees ; pain-free, mean +/- SD, 48.6 degrees +/-7.1 degrees ; P50y) revealed an interaction, with a statistically significant difference in head posture for younger participants with NP compared with younger pain-free participants (NP, mean +/- SD, 46.1 degrees +/-6.7 degrees ; pain-free, mean +/- SD, 51.8 degrees +/-5.9 degrees ; P.05; CI for the difference between groups, -4.9 degrees -4.2 degrees ). No other differences were found between patients and pain-free participants. Younger patients with chronic nontraumatic NP were shown to have a more forward head posture in standing than matched pain-free participants. However, the difference, although statistically significant, was perhaps too small to be clinically meaningful.

    2012-01-01

    Purpose: To investigate the frequency of non-traumatic acute abdominal emergencies in end-stage renal disease (ESRD) (peritoneal dialysis (PD) and haemodialysis (HD)) patients and in the general population as diagnosed by computed tomography (CT) imaging. Methods: The abdominal CT findings of ESRD patients with non-traumatic acute abdominal pain during the years 2001–2010 have been retrospectively evaluated. Thirty-three HD (14 females, 19 males, mean age: 62 ± 10.5) and 22 PD patients (12 females, 10 males, mean age: 59 ± 9.4) with acute abdominal pathology based on their CT scans have been included into the study. In addition, 127 individuals (68 females, 59 males, mean age: 40.7 ± 12.8) with normal renal functions who presented with non-traumatic acute abdominal pain diagnosed with an acute abdominal pathology based on their CT scans have been prospectively evaluated during the years 2009–2010. Results: While the most frequent etiology in PD patients was peritonitis (45.4%), acute pancreatitis (13.6%) and perforation (18.1), and in HD patients it was nonocclusive mesenteric ischemia (18.1%) and spontaneous intraabdominal bleeding (21.2%). The basic causes of acute abdomen in the general population were ureteral stone (34.6%) and appendicitis (18.1%). Conclusions: The causes of acute abdominal pain in ESRD patients is significantly different when compared to the general population. And within this special patient population the etiology of acute abdomen differs depending on the renal replacement therapy modality they are receiving. Thus, the causes of acute abdomen in PD patients are mostly peritonitis, acute pancreatitis, and perforation, while being mostly nonocclusive mesenteric ischemia and spontaneous intraabdominal bleeding in patients receiving HD therapy.

    Subarachnoid hemorrhage results in significant long-lasting neurologic sequelae. Here, we investigated whether human albumin improves long-term outcomes in experimental subarachnoid hemorrhage and whether neurovascular remodeling is involved in the protection of albumin. Laboratory investigation. Hospital research laboratory. Male Sprague-Dawley rats. Rats underwent subarachnoid hemorrhage by endovascular perforation. Albumin of either 0.63 or 1.25 g/kg was injected IV immediately after the surgery. Modified Garcia test, beam-walking test, novel object recognition, and Morris water maze were employed to determine the behavioral deficits. The effects of albumin on early neurovascular dysfunction and chronic synaptic plasticity were also studied. Both doses of albumin significantly improved the sensorimotor scores (F = 31.277; p = 0.001) and cognitive performance (F = 7.982; p = 0.001 in novel object recognition test; and F = 3.431; p = 0.026 in the latency analysis of Morris water maze test) for at least 40 days after subarachnoid hemorrhage. There were remarkable microvasculature hypoperfusion, intracranial pressure rise, early vasoconstriction, neural apoptosis, and degeneration in subarachnoid hemorrhage rats, with albumin significantly attenuating such neurovascular dysfunction. Furthermore, albumin markedly prevented blood-brain barrier disruption, as indicated by less blood-brain barrier leakage, preserved blood-brain barrier-related proteins, and dampened gelatinase activities. The expressions of key synaptic elements were up-regulated with albumin supplementation in both acute and chronic phases. Accordingly, a higher dendritic spine density was observed in the prefrontal and hippocampal areas of albumin-treated subarachnoid hemorrhage animals. Albumin at low-to-moderate doses markedly improves long-term neurobehavioral sequelae after subarachnoid hemorrhage, which may involve an integrated process of neurovascular remodeling.

    Acute aneurysmal subarachnoid hemorrhage (SAH) is a medical and neurosurgical emergency from ruptured brain aneurysm. Aneurysmal SAH is identified on brain computed tomography (CT) as increased density of basal cisterns and subarachnoid spaces from acute blood products. Aneurysmal SAH-like pattern on CT appears as an optical illusion effect of hypodense brain parenchyma and/or hyperdense surrounding cerebral cisterns and blood vessels termed as "pseudo-subarachnoid hemorrhage" (pseudo-SAH). We reviewed clinical, laboratory, and radiographic data of all SAH diagnoses between January 2013 and January 2018, and found subsets of nonaneurysmal SAH, originally suspected to be aneurysmal in origin. We performed a National Library of Medicine search methodology using terms "subarachnoid hemorrhage," "pseudo," and "non-aneurysmal subarachnoid hemorrhage" singly and in combination to understand the sensitivity, specificity, and precision of pseudo-SAH. Over 5 years, 230 SAH cases were referred to our tertiary academic center and only 7 (3%) met the definition of pseudo-SAH. Searching the National Library of Medicine using subarachnoid hemorrhage yielded 27,402 results. When subarachnoid hemorrhage and pseudo were combined, this yielded 70 results and sensitivity was 50% (n = 35). Similarly, search precision was relatively low (26%) as only 18 results fit the clinical description similar to the 7 cases discussed in our series. Aneurysmal SAH pattern on CT is distinct from nonaneurysmal and pseudo-SAH patterns. The origin of pseudo-SAH terminology appears mostly tied to comatose cardiac arrest patients with diffuse dark brain Hounsfield units and cerebral edema, and is a potential imaging pitfall in acute medical decision-making.

    Full Text Available Objective To investigate the clinical diagnosis and treatment of adult medulloblastoma seeding in the intracranial-spinal subarachnoid space. Methods Eleven cases of adult medulloblastoma seeding in the intracranial-spinal subarachnoid space were retrospectively analyzed on the clinical features, cerebrospinal fluid (CSF cytology, radiological characteristics and treatments. Results All patients underment neurosurgical procedures to remove medulloblastomas. In 10 patients, tumor was removed through suboccipital posterior midline approach and in one patient through post-sigmoid sinus approach. In 7 patients tumor cell seeding was found in the intracranial-spinal subarachnoid space before postoperative radiotherapy and disappeared after radiological and chemical treatment, while in other 4 patients tumor cell seeding was found in the intracranial-spinal subarachnoid space at 3 months to 3 years follow-up period (average 20 months after radiotherapy. In 2 of all the patients tumor cells were found by CSF cytology before operation. All the patients were treated with radiotherapy and adjuvant chemotherapy. Two patients were still alive, while 9 patients were dead. Conclusions Patients with adult medulloblastoma seeding in intracranial-spinal subarachnoid space have a poor prognosis. In the diagnosis of adult medulloblastomas seeding in the intracranial-spinal subarachnoid space, MRI is more sensitive than CSF cytology. Once the seeding in intracranial-spinal subarachnoid space was found, the patients should be treated with radiotherapy and adjuvant chemotherapy, which can prolong the survival time and improve the quality of life. DOI: 10.3969/j.issn.1672-6731.2015.10.012

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

    LENUS (Irish Health Repository)

    Brady, A P

    2012-01-31

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

    BACKGROUND: In early postpartum haemorrhage (PPH), a low concentration of fibrinogen is associated with excessive subsequent bleeding and blood transfusion. We hypothesized that pre-emptive treatment with fibrinogen concentrate reduces the need for red blood cell (RBC) transfusion in patients...... and the fibrinogen concentration at inclusion. The primary outcome was RBC transfusion up to 6 weeks postpartum. Secondary outcomes were total blood loss, total amount of blood transfused, occurrence of rebleeding, haemoglobin ... concentrate, thereby significantly increasing fibrinogen concentration compared with placebo by 0.40 g litre(-1) (95% confidence interval, 0.15-0.65; P=0.002).

    2006-12-01

    Being highly pathogenic for human and nonhuman primates and the subject of former weapon programmes makes Ebola virus one of the most feared pathogens worldwide today. Due to a lack of licensed pre- and postexposure intervention, the current response depends on rapid diagnostics, proper isolation procedures and supportive care of case patients. Consequently, the development of more specific countermeasures is of high priority for the preparedness of many nations. Over the past years, enhanced research efforts directed to better understand virus replication and pathogenesis have identified potential new targets for intervention strategies. The authors discuss the most promising therapeutic approaches for Ebola haemorrhagic fever as judged by their efficacy in animal models. The current development in this field encourages discussions on how to move some of the experimental approaches towards clinical application.

    The cardiovascular effects of the opioid mixed agonist-antagonist, meptazinol, and the opioid antagonist, naloxone, have been evaluated in conscious rats, anaesthetized rats and anaesthetized cats following the induction of haemorrhagic shock. The mean arterial pressure of conscious rats decreased by 17-29 mmHg following a haemorrhage of 20% of blood volume. Meptazinol (17 mg kg-1, i.m.) administered after haemorrhage evoked a rapid and sustained increase in mean arterial pressure to pre-haemorrhage levels. Naloxone (10 mg kg-1, i.v.) also increased mean arterial pressure to a level significantly higher than post-haemorrhage values. Neither haemorrhage nor subsequent drug treatments evoked significant changes in the heart rates of conscious rats. In anaesthetized rats, 20% haemorrhage evoked decreases in mean arterial pressure, heart rate and cardiac output. Blood flow to the heart, skin, skeletal muscle, kidneys, spleen and liver (arterial) was decreased. Meptazinol and naloxone increased blood pressure and total peripheral resistance, but did not significantly alter heart rate or cardiac output. Hepatic arterial flow decreased further in both drug and vehicle treated groups. In addition meptazinol slightly reduced skeletal muscle flow. In anaesthetized cats 40% haemorrhage decreased mean arterial pressure by 46 +/- 3 mmHg. An intravenous infusion of either meptazinol or naloxone (cumulative 2 mg kg-1, i.v.) partially restored blood pressure. In experimental animal models of haemorrhagic shock, meptazinol has a similar cardiovascular profile to naloxone. The established analgesic activity of meptazinol may confer an advantage in some shock states. PMID:4052729

    This study describes the burden of bleeding oesophageal varices at the main tertiary referral centre in Accra. Retrospective design to describe the endoscopic spectrum and review mortality data following acute upper gastro-intestinal bleeding at the Korle-Bu Teaching Hospital. Endoscopic data was reviewed in the Endoscopy Unit between 2007 and 2010. Mortality data was collated from the Department of Medicine between 2010 and 2013. The study questionnaire compiled clinical and demographic characteristics, endoscopic diagnoses, length of hospital admission and treatment regimens. Aetiology and time-trend analysis of mortality rates following acute upper gastro-intestinal bleeding; variceal bleeding treatment modalities. On review of the endoscopic diagnoses, gastro-oesophageal varices were identified in 21.9% of cases followed by gastritis 21.7%, duodenal ulcer, 17.0%, and gastric ulcer, 13.2%. Gastro-oesophageal varices were the predominant cause of death from acute upper gastro-intestinal haemorrhage from 46% in 2010 to 76% in 2013. Outcomes following acute upper gastro-intestinal bleeding were dismal with some 38% of fatalities occurring within the first 24 hours. Injection sclerotherapy was the dominant endoscopic modality for secondary prevention of variceal bleeding in comparison with band ligation, mainly as a result of cost and availability. At the tertiary centre in Accra, variceal bleeding is an increasingly common cause of acute upper gastro-intestinal haemorrhage in comparison with previous reviews in Ghana. Its significantly high in-hospital mortality reflects inadequate facilities to deal with this medical emergency. A strategic approach to care with endoscopic services equipped with all the necessary therapeutic interventions will be vital in improving the outcomes of variceal bleeding in Ghana.

  9. ROLE OF HYSTEROSCOPY IN THE MANAGEMENT OF SECONDARY POSTPARTUM HAEMORRHAGE

    Full Text Available INTRODUCTION Secondary postpartum haemorrhage [PPH] or puerperal haemorrhage, though rare can sometimes cause severe morbidity needing prolonged hospitalisation. Majority of the cases can be managed medically, a few of them requiring surgical interventions. With retained placental tissue being a common cause, emptying the uterus in the puerperium can be difficult and dangerous too as the wall is soft and perforation chances are high. Hysteroscopic evaluation of the puerperal uterus gives us a better picture of the retained bits of placental tissue, and helps in complete evacuation of the tissue without causing much trauma to the fragile uterine wall. It is also more specific than ultrasonogram [USG] to rule out the presence of retained tissue. MATERIAL AND METHODS 17 patients who had secondary PPH and did not respond to the initial medical management were included in the study. Hysteroscopy was done in these cases. Definitive pathology was found in 12 cases; 7 cases had polypoidal tissue [retained bits of placenta], 3 cases had placental tissue adherent to the caesarean scar [placenta accreta] and 2 cases had submucous fibroids. RESULTS In cases which had retained placental bits, the tissue could be visualised, its exact location noted and the entire tissue could be removed without inciting much trauma to the uterine wall. In cases with placenta accreta, gentle extraction of the adherent tissue could be done without traumatising the scar. In one case which had multiple fibroids with irregular uterine cavity, hysteroscopy helped in localising the retained tissue. CONCLUSION Hysteroscopy is a useful modality in managing cases of secondary PPH, who have persistent bleeding in the postpartum period.

    To identify predictors of in-hospital mortality in patients with aneurysmal subarachnoid hemorrhage and to estimate their impact. Retrospective analysis of prospective data from a nationwide multicenter registry on all aneurysmal subarachnoid hemorrhage cases admitted to a tertiary neurosurgical department in Switzerland (Swiss SOS [Swiss Study on Aneurysmal Subarachnoid Hemorrhage]; 2009-2015). Both clinical and radiological independent predictors of in-hospital mortality were identified, and their effect size was determined by calculating adjusted odds ratios (aORs) using multivariate logistic regression. Survival was displayed using Kaplan-Meier curves. Data of n=1866 aneurysmal subarachnoid hemorrhage patients in the Swiss SOS database were available. In-hospital mortality was 20% (n=373). In n=197 patients (10.6%), active treatment was discontinued after hospital admission (no aneurysm occlusion attempted), and this cohort was excluded from analysis of the main statistical model. In the remaining n=1669 patients, the rate of in-hospital mortality was 13.9% (n=232). Strong independent predictors of in-hospital mortality were rebleeding (aOR, 7.69; 95% confidence interval, 3.00-19.71; P <0.001), cerebral infarction attributable to delayed cerebral ischemia (aOR, 3.66; 95% confidence interval, 1.94-6.89; P <0.001), intraventricular hemorrhage (aOR, 2.65; 95% confidence interval, 1.38-5.09; P =0.003), and new infarction post-treatment (aOR, 2.57; 95% confidence interval, 1.43-4.62; P =0.002). Several-and among them modifiable-factors seem to be associated with in-hospital mortality after aneurysmal subarachnoid hemorrhage. Our data suggest that strategies aiming to reduce the risk of rebleeding are most promising in patients where active treatment is initially pursued. URL: http://www.clinicaltrials.gov.

    Cognitive deficits after aneurysmal subarachnoid hemorrhage (SAH) are common and disabling. Patients who experience delayed deterioration associated with vasospasm are likely to have cognitive deficits, particularly problems with executive function, verbal and spatial memory. Here, we report neurophysiological and pathological mechanisms underlying behavioral deficits in a murine model of SAH. On tests of spatial memory, animals with SAH performed worse than sham animals in the first week and one month after SAH suggesting a prolonged injury. Between three and six days after experimental hemorrhage, mice demonstrated loss of late long-term potentiation (L-LTP) due to dysfunction of the NMDA receptor. Suppression of innate immune cell activation prevents delayed vasospasm after murine SAH. We therefore explored the role of neutrophil-mediated innate inflammation on memory deficits after SAH. Depletion of neutrophils three days after SAH mitigates tissue inflammation, reverses cerebral vasoconstriction in the middle cerebral artery, and rescues L-LTP dysfunction at day 6. Spatial memory deficits in both the short and long-term are improved and associated with a shift of NMDA receptor subunit composition toward a memory sparing phenotype. This work supports further investigating suppression of innate immunity after SAH as a target for preventative therapies in SAH. Copyright © 2016 Elsevier Inc. All rights reserved.

    Delayed ischemic neurological deficit (DIND) after the rupture of cerebral aneurysm remains of the most difficult problems encountered by neurosurgeons. Since the introduction of CT scanning, its clinical application has clarified a close relationship between DIND and the features of subarachnoid hemorrhage (SAH) on CT images. Fisher et al proposed a grading system for SAH based on CT equipment used in the 1980s. Using third-generation CT equipment, we developed a new SAH-grading system to predict the incidence and severity of DIND more precisely. SAH in 109 patients were retrospectively classified according to the CT findings regarding location and density as THIN, THICK, and PACKED (or DENSE). In the THIN group, no DIND appeared. In 44% of patients with THICK group, DIND developed although it was reversible in 75%. On the other hand, DIND was irreversible in 70% of the 56% of PACKEND (or DENSE) group in whom it developed. Moreover, if sequential CT scan demonstrated decrease of the size and density of the SAH, DIND may rarely developed. We therefore conclude that, in order to assess the risk of DIND more precisely, it is very important to obtain repeat CT scans before operation. (author)

    Memory deficits for survivors of aneurysmal subarachnoid hemorrhage (SAH) are common, however, the nature of these deficits is not well understood. In this study, 24 patients with SAH and matched control participants were asked to study six lists containing words from four different categories. For half the lists, the categories were presented together (organized lists). For the remaining lists, the related words were presented randomly to maximize the use of executive processes such as strategy and organization (unorganized lists). Across adjoining lists, there was overlap in the types of categories given, done to promote intrusions. Compared to control participants, SAH patients recalled a similar number of words for the organized lists, but significantly fewer words for the unorganized lists. SAH patients also reported more intrusions than their matched counterparts. Separating patients into anterior communicating artery ruptures (ACoA) and ruptures in other regions, there was a recall deficit only for the unorganized list for those with ACoA ruptures and deficits across both list types for other rupture locations. These results suggest that memory impairment following SAH is likely driven by impairment in the executive components of memory, particularly for those with ACoA ruptures. Such findings may help direct future cognitive-therapeutic programs.

    Aneurysmal subarachnoid hemorrhage (aSAH) is one of the leading causes of neurologic disability accounting for dismal long term survival rates. aSAH leads to a sudden increase in intracranial pressure and a massive sympathetic discharge. Excessive sympathetic stimulation leads to catecholamine mediated myocardial dysfunction and hemodynamic instability which may critically hamper brain perfusion and oxygenation. In the setting of acute aSAH, administration of vasoactive drugs aims at stabilizing impaired hemodynamics. However, studies have shown that conventional treatment with vasoactive drugs that lead to Ca(+2) overload and increase myocardial oxygen consumption, fail to restore hemodynamics and decrease cerebral blood flow. Levosimendan is a non-adrenergic inotropic Ca(+2) sensitizer with not only beneficial hemodynamic properties but also pleiotropic effects, contributing to its cardioprotective and neuroprotective role. Although there have been limited data available regarding the use of levosimendan in patients with aSAH, current evidence suggests that levosimendan may have a role in the setting of post-aSAH cardiomyopathy and decreased cerebral blood flow both in the emergency departments and in intensive care units. The purpose of this review is to provide an overview of studies of levosimendan therapy for aSAH, and describe current knowledge about the effects of levosimendan in the management of aSAH.

    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.

    To identify whether abnormal neural activity, in the form of epileptiform discharges and rhythmic or periodic activity, which we term here ictal-interictal continuum abnormalities (IICAs), are associated with delayed cerebral ischemia (DCI). Retrospective analysis of continuous electroencephalography (cEEG) reports and medical records from 124 patients with moderate to severe grade subarachnoid hemorrhage (SAH). We identified daily occurrence of seizures and IICAs. Using survival analysis methods, we estimated the cumulative probability of IICA onset time for patients with and without delayed cerebral ischemia (DCI). Our data suggest the presence of IICAs indeed increases the risk of developing DCI, especially when they begin several days after the onset of SAH. We found that all IICA types except generalized rhythmic delta activity occur more commonly in patients who develop DCI. In particular, IICAs that begin later in hospitalization correlate with increased risk of DCI. IICAs represent a new marker for identifying early patients at increased risk for DCI. Moreover, IICAs might contribute mechanistically to DCI and therefore represent a new potential target for intervention to prevent secondary cerebral injury following SAH. These findings imply that IICAs may be a novel marker for predicting those at higher risk for DCI development. Copyright © 2017 International Federation of Clinical Neurophysiology.

    Our objective was to evaluate the effect of cannabis use on hospitalizations for aneurysmal subarachnoid hemorrhage (aSAH). The Nationwide Inpatient Sample (2004-2011) was used to identify all patients (age 15-54) with a primary diagnosis of aSAH (International Classification of Diseases, Ninth Edition, Clinical Modification 430). We identified patients testing positive for cannabis use using all available diagnosis fields. The incidence and characteristics of aSAH hospitalizations among cannabis users were examined. Bivariate and multivariate analyses were performed to determine the effect of cannabis use on aSAH and in-hospital outcomes. Prior to adjustment, the incidence of aSAH in the cannabis cohort was slightly increased relative to the noncannabis cohort (relative risk: 1.07, 95% confidence interval [CI]: 1.02-1.11). Cannabis use in aSAH was more frequent among younger patients (40.44 ± 10.17 versus 43.74 ± 8.68, P recreational marijuana use is independently associated with an 18% increased likelihood of aSAH. Further case-control studies may analyze inpatient outcomes and other understudied mechanisms behind cannabis-associated stroke. Copyright © 2015 National Stroke Association.

    Despite decades of study, subarachnoid hemorrhage (SAH) continues to be a serious and significant health problem in the United States and worldwide. The mechanisms contributing to brain injury after SAH remain unclear. Traditionally, most in vivo research has heavily emphasized the basic mechanisms of SAH over the pathophysiological or morphological changes of delayed cerebral vasospasm after SAH. Unfortunately, the results of clinical trials based on this premise have mostly been disappointing, implicating some other pathophysiological factors, independent of vasospasm, as contributors to poor clinical outcomes. Delayed cerebral vasospasm is no longer the only culprit. In this review, we summarize recent data from both experimental and clinical studies of SAH and discuss the vast array of physiological dysfunctions following SAH that ultimately lead to cell death. Based on the progress in neurobiological understanding of SAH, the terms “early brain injury” and “delayed brain injury” are used according to the temporal progression of SAH-induced brain injury. Additionally, a new concept of the vasculo-neuronal-glia triad model for SAH study is highlighted and presents the challenges and opportunities of this model for future SAH applications.

    Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs. The group researched all articles and major foreign CPGs published in English until December 2015 using several search engines. Based on these articles, levels of evidence and grades of recommendations were determined by our society as well as by other related Quality Control Committees from neurointervention, neurology and rehabilitation medicine. The Korean version of the CPGs for aSAHs includes risk factors, diagnosis, initial management, medical and surgical management to prevent rebleeding, management of delayed cerebral ischemia and vasospasm, treatment of hydrocephalus, treatment of medical complications and early rehabilitation. The CPGs are not the absolute standard but are the present reference as the evidence is still incomplete, each environment of clinical practice is different, and there is a high probability of variation in the current recommendations. The CPGs will be useful in the fields of clinical practice and research. PMID:29526058

    CT scans were analysed retrospectively in 130 patients with subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysm to evaluate the relationship of the locations of aneurysms and the patterns of hemorrhage. Hemorrhage corresponded to the site of aneurysmal origin in a general way and in more specific ways to anterior communicating and middle cerebral artery aneurysms when there was parenchymal or cisternal hemorrhage. In anterior communicating artery aneurysm, SAH in the interhemispheric fissure, both sylvian fissures, and basal cistern was usually noted and intracerebral hemorrhage in anteroinferior frontal lobe was sometimes associated. In cases of middle cerebral artery aneurysm, hemorrhage in the ipsilateral sylvian fissure, interhemispheric fissure, and ipsilateral basal cistern was usual. Intracerebral hemorrhage in lateral temporal lobe was sometimes associated. Posterior communicating artery aneurysm demonstrated SAH in the ipsilateral basal cistern or in entire cisternal spaces specifically, so with higher incidence of involvement of the quadrigeminal and superior cerebellar cistern than anterior cerebral or middle cerebral artery aneurysm. We suggest the locations of aneurysm might be predicted with patterns of SAH and / or associated intracerebral hemorrhage with CT

    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.

    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.

    This review examines the best available evidence on the aetiology of childhood acute non-traumatic coma in resource-poor countries (RPCs), discusses the challenges associated with management, and explores strategies to address them. Publications in English and French which reported on studies on the aetiology of childhood non-traumatic coma in RPCs are reviewed. Primarily, the MEDLINE database was searched using the keywords coma, unconsciousness, causality, aetiology, child, malaria cerebral, meningitis, encephalitis, Africa, Asia, and developing countries. 14 records were identified for inclusion in the review. Cerebral malaria (CM) was the commonest cause of childhood coma in most of the studies conducted in Africa. Acute bacterial meningitis (ABM) was the second most common known cause of coma in seven of the African studies. Of the studies in Asia, encephalitides were the commonest cause of coma in two studies in India, and ABM was the commonest cause of coma in Pakistan. Streptococcus pneumoniae was the most commonly isolated organism in ABM. Japanese encephalitis, dengue fever and enteroviruses were the viral agents most commonly isolated. Accurate diagnosis of the aetiology of childhood coma in RPCs is complicated by overlap in clinical presentation, limited diagnostic resources, disease endemicity and co-morbidity. For improved outcomes, studies are needed to further elucidate the aetiology of childhood coma in RPCs, explore simple and practical diagnostic tools, and investigate the most appropriate specific and supportive interventions to manage and prevent infectious encephalopathies.

    In patients with non-traumatic osteonecrosis of the femoral head (ONFH), the shoulder is one of the major affected sites secondary to the proximal and distal femur in cases of multiple osteonecrosis. The present study attempted to investigate whether technetium bone scintigraphy is useful for screening of non-traumatic osteonecrosis of the shoulder (ONS).Design and patients. A total of 170 shoulder joints in 85 patients with ONFH were evaluated by bone scintigraphy and the findings compared with those of magnetic resonance imaging (MRI). The MR diagnosis was used as the gold standard.Results. Based on the diagnosis by MRI, ONS was detected in 43 shoulders of 27 patients (25%). All necrotic lesions were located in the humeral head. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value of bone scintigraphy for ONS detection were 65%, 81%, 77%, 54% and 87%, respectively. When the necrotic angle of the lesions on the mid-coronal MRI was more than 40 , the sensitivity of bone scintigraphy for ONS detection increased to 88% (21/24 shoulders).Conclusion. Bone scintigraphy may be useful for demonstrating medium or large ONS lesions on screening of patients with ONFH. (orig.)

    2016-06-01

    Full Text Available Subarachnoid pleural fistulas are rare. They have been described as complications of thoracic surgery, penetrating injuries and spinal surgery, among others. We present the case of a 3-year-old female child, who suffer spinal cord trauma secondary to a car accident, developing a posterior subarachnoid pleural fistula. To our knowledge this is the first reported case of a pediatric patient with subarachnoid pleural fistula resulting from closed trauma, requiring intensive multimodal management. We also present a management algorithm and a proposed classification. The diagnosis of this pathology is difficult when not associated with neurological deficit. A high degree of suspicion, multidisciplinary management and timely surgical intervention allow optimal management.

    BACKGROUND AND PURPOSE: Data on the incidence of stroke subtypes among ethnic minority groups are limited. We assessed ethnic differences in the incidence of stroke subtypes in the Netherlands. METHODS: A Dutch nationwide register-based cohort study (n=7 423 174) was conducted between 1998 and 2010....... We studied the following stroke subtypes: ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. Cox proportional hazard models were used to estimate incidence differences between first-generation ethnic minorities and the Dutch majority population (ethnic Dutch). RESULTS: Compared.......16-0.72), and subarachnoid hemorrhage (0.42; 0.20-0.88 and 0.34; 0.17-0.68) compared with ethnic Dutch counterparts.

    CT scan and fundus oculi of subarachnoid hemorrhage due to ruptured cerebral aneurysm were investigated in 42 patients who were admitted between January, 1980, and August, 1984. Fundal hemorrhage (FH) was observed in 22 patients. The patients with FH showed a worse clinical grade (Hunt Kosnik) on admission than those without FH. The mortality rate of patients with FH was 64 %, much higher than the 5 % rate of those without FH. Moreover, the patients with FH showed more trouble in daily living than those without FH. CT scans of patients with FH usually showed severe subarachnoid hemorrhage (SAH), whereas those of patients without FH showed only mild hemorrhage. These findings suggest that fundal hemorrhage is caused by acute intracranial hypertension following subarachnoid hemorrhage due to a ruptured cerebral aneurysm. However, no significant correlation between the laterality of FH and the hemispheric dominancy of SAH could be demonstrated. (author)

    Early recognition and treatment of meningococcal disease improves its outcome. Haemorrhagic rash is one of the most specific signs that parents can learn to recognise. To determine the percentage of parents able to recognise a haemorrhagic rash and perform the tumbler test. 123 parents of children consulting for mild injuries were interviewed about the significance and recognition of haemorrhagic rash in febrile children. Although 88% of parents undressed their children when they were febrile, it was never to look specifically for a skin rash. Only 7% (95% CI 3% to 12%) were able to recognise a petechial rash and knew the tumbler test. Information campaigns about the significance of haemorrhagic rash and about the tumbler test are needed.

    A consecutive series of 103 patients, 58% male with mean age of 62 year (range 40-75 years), admitted with supratentorial stroke in our teaching hospital were studied. All patients had Computer Tomography scan brain done after clinical evaluation and application of Allen stroke score. Computer Tomography Scan confirmed thrombotic stroke in 55 (53%) patients and haemorrhagic stroke in 48 (47%) patients. Out of the 55 patients with definitive thrombotic stroke on Computer Tomography Scan, Allen stroke score suggested infarction in 67%, haemorrhage in 6% and remained inconclusive in 27% of cases. In 48 patients with definitive haemorrhagic stroke on Computer Tomography Scan, Allen stroke score suggested haemorrhage in 60%, infarction in 11% and remained inconclusive in 29% of cases. The overall accuracy of Allen stroke score was 66%. (author)

    To determine the risk factors for severe postpartum haemorrhage. A case control study. Mulago hospital labour wards, Kampala, Uganda. One hundred and six mothers with severe postpartum haemorrhage were recruited between 15th November 2001 and 30th November 2002 and were compared with 500 women who had normal delivery. The predictors for postpartum haemorrhage were co-existing hypertension (O.R 9.3, 95% CI: 1.7-51.7), chronic anaemia (OR 17.3, 95% CI: 9.5-31.7), low socio economic background (OR 5.3, 95% CI: 3.0, 9.2), past history of postpartum haemorrhage (OR 3.6, 95% CI: 1.1-11.8), previous delivery by Caesarean section (OR 7.5, 95% CI: 3.5-14.3), long birth interval of more than sixty months (OR 5.2, 95% CI: 2.1-13.0), prolonged third stage (OR 49.1, 95% CI: 8.8-342.8) and non use of oxytocics (OR 4.3%, 95% CI: 1.2-15.3). Severe postpartum haemorrhage is common in our environment and is associated with a high maternal morbidity and mortality. The determinants of postpartum haemorrhage are useful in identifying mothers at risk and together with the services of a skilled birth attendant at delivery will prevent postpartum haemorrhage and reduce the maternal morbidity and mortality associated with this condition. In our study, the following risk factors were identified: pre-existing hypertension, chronic anaemia, low socio-economic background, history of postpartum haemorrhage, previous delivery by Caesarean section, longbirth interval of more than sixty months, prolonged third stage and non use of oxytocics were found to be significant.

    We assessed the therapeutic indications for aneurysmal subarachnoid hemorrhage (SAH) in aged people. Between April 1999 and March 2002, 142 patients with aneurysmal SAH were treated and enrolled in this study. They were divided into 3 groups: 33 patients 75 years old and older (Group A, 23.2%), 37 between 65 and 74 years old (Group B, 26.1%), and 72 64 years old and younger (Group C, 47.4). Hunt and Kosnik grades, Fisher's CT classifications and clinical outcome were evaluated in each group. Clinical outcome was measured by Glasgow Outcome Scale, and good recovery and moderately disabled were defined as favorable outcome. Group A had a significantly higher incidence of serious Hunt and Kosnik grades of patients compared with the other 2 groups (p<0.05, <0.01). Fisher's CT classification was also more severe in Group A than Group C (p<0.05). Therefore the rate of radical treatments was significantly lower in Group A (45.5%) compared with Group B (73.0%) and C (86.1%). Only 4 of the 33 patients (12.1%) with favorable outcome were in Group A, whereas the rates of favorable outcome in Group B and C were 54.1 and 62.5%, respectively. Group A had a significantly poor outcome compared with the other 2 groups. Particularly, none of the patients in Group A with Hunt and Kosnik Grades 4-5 and Fisher's Classification 4 had favorable outcome. Since there were no significant differences in the rate of radical treatments and clinical outcome between Group B and C, aged people 74 years old and younger should be actively treated in the same manner as the young. In aged people 75 years old and older, however, radical treatment should be restricted to those with Hunt and Kosnik Grade 1-3 and Fisher's CT Classification 2-3. (author)

    The incidence of cannabis use in patients with aneurysmal subarachnoid hemorrhage (aSAH) and its impact on morbidity, mortality, and outcomes are unknown. Our objective was to evaluate the relationship between cannabis use and outcomes in patients with aSAH. Records of consecutive patients admitted with aSAH between 2010 and 2015 were reviewed. Clinical features and outcomes of aSAH patients with negative urine drug screen and cannabinoids-positive (CB+) were compared. Regression analyses were used to assess for associations. The study group consisted of 108 patients; 25.9% with CB+. Delayed cerebral ischemia was diagnosed in 50% of CB+ and 23.8% of urine drug screen negative patients (P=0.01). CB+ was independently associated with development of delayed cerebral ischemia (odds ratio, 2.68; 95% confidence interval, 1.03-6.99; P=0.01). A significantly higher number of CB+ than urine drug screen negative patients had poor outcome (35.7% versus 13.8%; P=0.01). In univariate analysis, CB+ was associated with the composite end point of hospital mortality/severe disability (odds ratio, 2.93; 95% confidence interval, 1.07-8.01; P=0.04). However, after adjusting for other predictors, this effect was no longer significant. We offer preliminary data that CB+ is independently associated with delayed cerebral ischemia and possibly poor outcome in patients with aSAH. Our findings add to the growing evidence on the association of cannabis with cerebrovascular risk. © 2016 American Heart Association, Inc.

    Natriuresis with polyuria is common after aneurysmal subarachnoid hemorrhage (aSAH). Previous studies have shown an increased risk of symptomatic cerebral vasospasm or delayed cerebral ischemia (DCI) in patients with hyponatremia and/or the cerebral salt wasting syndrome (CSW). However, natriuresis may occur in the absence of hyponatremia or hypovolemia and it is not known whether the increase in DCI in patients with CSW is secondary to a concomitant hypovolemia or because the physiology that predisposes to natriuretic peptide release also predisposes to cerebral vasospasm. Therefore, we investigated whether polyuria per se was associated with vasospasm and whether a temporal relationship existed. A retrospective review of patients with aSAH was performed. Exclusion criteria were admission more than 48 h after aneurysmal rupture, death within 5 days, and the development of diabetes insipidus or acute renal failure. Polyuria was defined as > 6 liters of urine in a 24 h period. Vasospasm was defined as a mean velocity > 120 m/s on Transcranial Doppler Ultrasonography (TCDs) or by evidence of vasospasm on computerized tomography (CT) or catheter angiography. Multivariable logistic regression was performed to assess the relationship between polyuria and vasospasm. 95 patients were included in the study. 51 had cerebral vasospasm and 63 met the definition of polyuria. Patients with polyuria were significantly more likely to have vasospasm (OR 4.301, 95% CI 1.378-13.419) in multivariate analysis. Polyuria was more common in younger patients (52 vs 68, p polyuria was clustered around the diagnosis of vasospasm and patients with polyuria developed vasospasm faster than those without polyuria. Polyuria is common after aSAH and is significantly associated with cerebral vasospasm. The development of polyuria may be temporally related to the development of vasospasm. An increase in urine volume may be a useful clinical predictor of patients at risk for vasospasm.

    Neuropeptide Y (NPY), a highly potent vasoconstrictive neuropeptide, is widely expressed in the human brain, regulating vessel diameter and cerebral blood flow. Earlier studies focusing on the possible role of NPY in the context of aneurismal subarachnoid hemorrhage (SAH) and vasospasm have produced conflicting results. However, despite extensive research efforts, the pathophysiological mechanisms underlying the SAH-related vasospasm and delayed cerebral ischemia (DCI) have not been clarified. We, therefore, attempted to investigate the role of NPY in SAH-induced vasospasm in a larger, well documented patient population utilizing modern analytical tools. We focused on the release of the potent vasoconstrictor NPY in cerebrospinal fluid (CSF) and blood, and its correlation to vasospasm and stroke in the early clinical stage. Thirty-seven patients with SAH and a control group consisting of 29 patients were included. Eighteen patients developed stroke, 21 patients met the Doppler sonographical criteria for vasospasm. Twenty-nine patients had aneurysms of the anterior circulation and four patients of the posterior circulation. All patients had ventricular drainage inserted and an arterial catheter. Blood and CSF were drawn daily for NPY analysis during a 10-day interval. The levels of NPY in CSF and plasma were significantly higher after SAH than in the control group (p = 0.001). The vasospasm group showed NPY levels in CSF which continuously ranged above the NPY levels of the non-vasospasm group (p = 0.001). Patients with stroke caused by vasospasm had significantly higher levels of NPY (p = 0.001). NPY is released excessively into blood and CSF following SAH. Patients with cerebral infarction caused by vasospasm had significantly higher levels of NPY. Our results indicate a certain role for NPY in the pathophysiology of vasospasm due to SAH and justify further studies in this area of research.

    OBJECT Deep vein thrombosis (DVT) is a common complication of aneurysmal subarachnoid hemorrhage (aSAH). The time period of greatest risk for developing DVT after aSAH is not currently known. aSAH induces a prothrombotic state, which may contribute to DVT formation. Using repeated ultrasound screening, the hypothesis that patients would be at greatest risk for developing DVT in the subacute post-rupture period was tested. METHODS One hundred ninety-eight patients with aSAH admitted to the Oregon Health & Science University Neurosciences Intensive Care Unit between April 2008 and March 2012 were included in a retrospective analysis. Ultrasound screening was performed every 5.2 ± 3.3 days between admission and discharge. The chi-square test was used to compare DVT incidence during different time periods of interest. Patient baseline characteristics as well as stroke severity and hospital complications were evaluated in univariate and multivariate analyses. RESULTS Forty-two (21%) of 198 patients were diagnosed with DVT, and 3 (2%) of 198 patients were symptomatic. Twenty-nine (69%) of the 42 cases of DVT were first detected between Days 3 and 14, compared with 3 cases (7%) detected between Days 0 and 3 and 10 cases (24%) detected after Day 14 (p < 0.05). The postrupture 5-day window of highest risk for DVT development was between Days 5 and 9 (40%, p < 0.05). In the multivariate analysis, length of hospital stay and use of mechanical prophylaxis alone were significantly associated with DVT formation. CONCLUSIONS DVT formation most commonly occurs in the first 2 weeks following aSAH, with detection in this cohort peaking between Days 5 and 9. Chemoprophylaxis is associated with a significantly lower incidence of DVT. PMID:26162047

  3. The Importance of Early Brain Injury after Subarachnoid Hemorrhage

    Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency that accounts for 5% of all stroke cases. Individuals affected are typically in the prime of their lives (mean age 50 years). Approximately 12% of patients die before receiving medical attention, 33% within 48 hours and 50% within 30 days of aSAH. Of the survivors 50% suffer from permanent disability with an estimated lifetime cost more than double that of an ischemic stroke. Traditionally, spasm that develops in large cerebral arteries 3-7 days after aneurysm rupture is considered the most important determinant of brain injury and outcome after aSAH. However, recent studies show that prevention of delayed vasospasm does not improve outcome in aSAH patients. This finding has finally brought in focus the influence of early brain injury on outcome of aSAH. A substantial amount of evidence indicates that brain injury begins at the aneurysm rupture, evolves with time and plays an important role in patients’ outcome. In this manuscript we review early brain injury after aSAH. Due to the early nature, most of the information on this injury comes from animals and few only from autopsy of patients who died within days after aSAH. Consequently, we began with a review of animal models of early brain injury, next we review the mechanisms of brain injury according to the sequence of their temporal appearance and finally we discuss the failure of clinical translation of therapies successful in animal models of aSAH.

    2012-01-01

    Churg-Strauss syndrome (CSS) is a systemic necrotizing vasculitis of the small and medium vessels, associated with extravascular eosinophilic granulomas, peripheral eosinophilia, and asthma. The exact etiology of CSS is unknown. This syndrome commonly affects the lungs, peripheral nerves, skin, heart, and gastrointestinal tract, but rarely the central nervous system. Subarachnoid and intracerebral hemorrhage in CSS patients is extremely rare; however, clinicians should consider that CSS may be a cause of intracranial hemorrhage and its high rate of mortality and morbidity. The authors report on two cases of subarachnoid and intracerebral hemorrhage with CSS and discuss a brief review of CSS. PMID:23210058

    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.

    Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.

    OBJECT Subarachnoid hemorrhage (SAH) is often accompanied by pulmonary complications, which may lead to poor outcomes and death. This study investigated the incidence and cause of pulmonary edema in patients with SAH by using hemodynamic monitoring with PiCCO-plus pulse contour analysis. METHODS A total of 204 patients with SAH were included in a multicenter prospective cohort study to investigate hemodynamic changes after surgical clipping or coil embolization of ruptured cerebral aneurysms by using a PiCCO-plus device. Changes in various hemodynamic parameters after SAH were analyzed statistically. RESULTS Fifty-two patients (25.5%) developed pulmonary edema. Patients with pulmonary edema (PE group) were significantly older than those without pulmonary edema (non-PE group) (p = 0.017). The mean extravascular lung water index was significantly higher in the PE group than in the non-PE group throughout the study period. The pulmonary vascular permeability index (PVPI) was significantly higher in the PE group than in the non-PE group on Day 6 (p = 0.029) and Day 10 (p = 0.011). The cardiac index of the PE group was significantly decreased biphasically on Days 2 and 10 compared with that of the non-PE group. In the early phase (Days 1-5 after SAH), the daily water balance of the PE group was slightly positive. In the delayed phase (Days 6-14 after SAH), the serum C-reactive protein level and the global end-diastolic volume index were significantly higher in the PE group than in the non-PE group, whereas the PVPI tended to be higher in the PE group. CONCLUSIONS Pulmonary edema that occurs in the early and delayed phases after SAH is caused by cardiac failure and inflammatory (i.e., noncardiogenic) conditions, respectively. Measurement of the extravascular lung water index, cardiac index, and PVPI by PiCCO-plus monitoring is useful for identifying pulmonary edema in patients with SAH.

  13. 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.

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

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

    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.

    Recurrent epistaxis in hereditary haemorrhagic telangiectasia (HHT) patients significantly decreases their quality of life. Treatment in therapy refractory patients is limited although various options have been tested so far. Herein, one patient is described that was treated for HHT for over 20 years with only intermediate benefits. As epistaxis duration and frequency increased continuously, bevacizumab 5 mg/kg was administered every 2 weeks. During the time of treatment (six doses) and up to 3 month afterwards clinical symptoms, blood pressure, cardiac output, pulmonary arterial hypertension (PAH), bleeding duration and frequency were assessed as criteria for treatment benefit. Duration and frequency of epistaxis decreased immediately after the first application resulting in reduced need of blood transfusions. After completion of six cycles, a further decrease in frequency and duration of bleeding was noted. Cardiac output and PAH decreased or remained stable, respectively, during time and after treatment. No increase in blood pressure could be found but a significant increase in heart rate was experienced after completion of all six applications. Unfortunately, the patient died due to a cerebral abscess. Bevacizumab led to an improvement of HHT related epistaxis, refractory to other treatments.

    Full Text Available INTRODUCTION Cardiac abnormalities are relatively common after acute neurologic injury. Disturbances can vary in severity from transient ECG abnormalities to profound myocardial injury and dysfunction. CNS is involved in the generation of cardiac arrhythmias and dysfunction even in an otherwise normal myocardium. AIM To find out proportion of ECG changes observed in ischaemic and haemorrhagic stroke. MATERIALS AND METHODS The Electrocardiographs of 100 patients with acute stroke were studied to find out the types of ECG abnormalities among different types of stroke. RESULTS In our study, the most common ECG abnormalities associated with stroke were prolonged QTc interval, ST-T segment abnormalities, prominent U wave and arrhythmias. Trop-I was positive in 12.8% patients with ECG changes. Statistical significance was found in association with Trop-I positivity and ST depression. CONCLUSION Usually patients with heart disease present with arrhythmias and Ischaemic like ECG changes. But these changes are also seen most often in the patients with presenting with stroke who didn’t have any past history of heart disease. This shows that arrhythmias and ischaemic ECG abnormalities are primarily evolved due to central nervous system disorders.

    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.

    The mechanism of reduction of cerebral circulation in the early phase of aneurysmal subarachnoid hemorrhage (SAH) has not yet been clarified. Previous studies have variously indicated that cerebral blood flow (CBF) reduction may be due to cerebral vasospasm, an elevation in intracranial pressure (ICP), constriction of intraparenchymal arterioles, or metabolic reduction. The aim of this study is to investigate the relationship between cerebral circulation and oxygen metabolism. In 36 patients with aneurysmal SAH, the values of mean cerebral blood flow (mCBF), cerebral metabolic rate of oxygen (GMRO 2 ) and oxygen extraction fraction (OEF) were measured by using single photon emission computed tomography (SPECT) with arterial blood drawing and oxygen saturation of internal jugular bulb blood (SjO 2 ) in the acute stage (1-3 days after onset) and the spasm stage (7-10 days after onset). The patients in our study were selected by using the following criteria: no history of cerebrovascular or cardiopulmonary diseases; under the age of 70; the ruptured aneurysm was treated by clipping or coil embolization within 72 hours after onset; no symptoms of cerebral vasospasm; no signs of cerebral ischemic change on CT scans. These patients were divided into 2 groups according to the World Federation of Neurological Surgeons (WFNS) grading classification; the mild group (Grades I and II) consisted of 27 cases and the severe group (Grade IV) consisted of 9 cases. We studied differences in mCBF CMRO 2 , and OEF between the mild group and severe group. In the mild group, mCBF, CMRO 2 , and OEF were significantly higher than in the severe group during both the acute and the spasm stage. Also mCBF showed a direct correlation with CMRO 2 . All the patients were kept under the following conditions: the bed was positioned so that the upper body was raised at an angle at 30 deg; blood pressure was maintained at 130-150 mmHg and PaCO 2 of arterial blood was maintained at 35-40 mmHg; ICP

    In a patient, the skin to Subarachnoid Space Depth (SSD) varies considerably at different levels of the spinal cord. It also varies from patient to patient at the same vertebral level as per age, sex and Body Mass Index (BMI). Estimation of the skin to SSD reduces complications related to spinal anaesthesia. To measure the skin to SSD in the Indian population and to find a formula for predicting this depth. Three hundred adult patients belonging to American Society of Anaesthesiologist class I and II, undergoing surgery using spinal anaesthesia in various surgical specialities of Gauhati Medical College were selected by systemic sampling for this prospective, observational study. Patients were divided into three groups: Group M containing male patients, Group F containing non-pregnant female patients, and Group PF containing pregnant female's patients. SSD was measured after performing lumbar puncture. The relationship between SSD and patient characteristics were studied, correlated and statistical analysis was used to find a formula for predicting the skin to SSD. Statistical analysis was done using Statistical Package for Social Sciences (SPSS 21.0, Chicago, IL, USA). One-way ANOVA with post-hoc(Bonferroni correction factor) analysis was applied to compare the three groups. Multivariate analysis was done for the covariates followed by a multivariate regression analysis to evaluate the covariates influencing SSD for each group separately. Mean SSD was 4.37±0.31cm in the overall population. SSD in adult males was 4.49±0.19cm which was significantly longer than that observed in female's 4.18±0.39cm which was comparable with SSD in parturient 4.43±0.19 cm. The formula for predicting the skin to SSD in the male population was 1.718+0.077×BMI+0.632×Height, in nonpregnant female population was 1.828+0.077×BMI+0.018×Height+0.007×Age and 0.748+0.209×BMI+4.703×Height-0.054×weight in parturient females, respectively.

    Spinal subarachnoid hematoma (SSH) is a rare condition, more commonly occurring after lumbar puncture for diagnostic or anesthesiological procedures. It has also been observed after traumatic events, in patients under anticoagulation therapy or in case of arteriovenous malformation rupture. In a very small number of cases no causative agent can be identified and a diagnosis of spontaneous SSH is established. The lumbar and thoracic spine are the most frequently involved segments and only seven cases of cervical spine SSH have been described until now. Differential diagnosis between subdural and subarachnoid hematoma is complex because the common neuroradiological investigations, including a magnetic resonance imaging (MRI), are not enough sensitive to exactly define clot location. Actually, confirmation of the subarachnoid location of bleeding is obtained at surgery, which is necessary to resolve the fast and sometimes dramatic evolution of clinical symptoms. Nonetheless, there are occasional reports on successful conservative treatment of these lesions. We present a peculiar case of subarachnoid hematoma of the craniocervical junction, developing after the rupture of a right temporal lobe contusion within the adjacent arachnoidal spaces and the following clot migration along the right lateral aspect of the foramen magnum and the upper cervical spine, causing severe neurological impairment. After surgical removal of the hematoma, significant symptom improvement was observed.

    Background If acute severe headache disappears early after its onset, the question arises whether subarachnoid hemorrhage (SAH) should still be ruled out. We studied the initial time-course and minimal duration of headache in a consecutive series of neurologically intact patients with spontaneous

    Convexal subarachnoid hemorrhage has been associated with different diseases, reversible cerebral vasoconstriction syndrome and cerebral amyloid angiopathy being the 2 main causes. To investigate whether headache at onset is determinant in identifying the underlying etiology for convexal subarachnoid hemorrhage. After searching in the database of our hospital, 24 patients were found with convexal subarachnoid hemorrhage in the last 10 years. The mean age of the sample was 69.5 years. We recorded data referring to demographics, symptoms and neuroimaging. Cerebral amyloid angiopathy patients accounted for 46% of the sample, 13% were diagnosed with reversible cerebral vasoconstriction syndrome, 16% with several other etiologies, and in 25%, the cause remained unknown. Mild headache was present only in 1 (9%) of the 11 cerebral amyloid angiopathy patients, while severe headache was the dominant feature in 86% of cases of the remaining etiologies. Headache is a key symptom allowing a presumptive etiological diagnosis of convexal subarachnoid hemorrhage. While the absence of headache suggests cerebral amyloid angiopathy as the more probable cause, severe headache obliges us to rule out other etiologies, such as reversible cerebral vasoconstriction syndrome. © 2013 American Headache Society.
