    Serra E Moura Garcia, C; Sokolova, A; Torre, M L; Amaro, C

    2016-01-01

    Acute Hemorrhagic Edema of Infancy is a small vessel leucocytoclastic vasculitis affecting young infants. It is characterized by large, target-like, macular to purpuric plaques predominantly affecting the face, ear lobes and extremities. Non-pitting edema of the distal extremities and low-grade fever may also be present. Extra-cutaneous involvement is very rare. Although the lesions have a dramatic onset in a twenty-four to forty-eight hour period, usually the child has a non-toxic appearance. In most cases there are no changes in laboratory parameters. The cutaneous biopsy reveals an inflammatory perivascular infiltrate. It is a benign and auto-limited disease, with complete resolution within two to three weeks leaving no sequelae in the majority of cases. No recurrences are described. We report a case of a 42-day old girl admitted at our hospital with Acute Hemorrhagic Edema of Infancy. PMID:26808448

Visual acuity was 6/36 and 6/60 in the right eye and left eye, respectively. Ophthalmoscopy showed bilateral peripapillary, subhyaloid and vitreous hemorrhage. Hematological evaluation revealed moderate anemia (hemoglobin: 93 g/L and mild thrombocytopenia (platelets: 120×109/L. She was co-managed by a hematologist and ophthalmologists; she was treated medically. Follow-up care during the next 6 weeks revealed spontaneous, partially resolving hemorrhage, with improvement of visual acuity. The purpose of this case report is to highlight ophthalmic involvement of ITP in this patient, despite her only-mild thrombocytopenia, and her spontaneous recovery, despite her receiving only medical treatment.Keywords: idiopathic thrombocytopenic purpura, subhyaloid hemorrhage, vitreous hemorrhage

    Zakaria, Zaitun

    2012-01-01

    Idiopathic intracranial hypertension is a headache syndrome with progressive symptoms of raised intracranial pressure. Most commonly, it is a slow process where surveillance and medical management are the main treatment modalities. We describe herein an acute presentation with bilateral sixth nerve palsies, papilloedema and visual deterioration, where acute surgical intervention was a vision-saving operation.

  9. MR imaging of acute hemorrhagic brain infarction

    Six patients with acute hemorrhagic brain infarct were imaged using spin-echo (SE) pulse sequences on a 1.5 Tesla MR scanner. Including two patients with repeated MR imaging, a total of eight examinations, all performed within 15 days after stroke, were analyzed retrospectively. Four patients revealed massive hemorrhages in the basal ganglia or cerebellum and three cases demonstrated multiple linear hemorrhages in the cerebral cortex. On T1-weighted images, hemorrhages were either mildly or definitely hyperintense relative to gray matter, while varied from mildly hypointense to hyperintense on T2-weighted images. T1-weighted images were superior to T2-weighted images in detection of hemorrhgage. CT failed to detect hemorrhage in two of five cases: indicative of MR superiority to CT in the diagnosis of acute hemorrhagic infarcts. (author)

  11. Acute and subacute idiopathic interstitial pneumonias.

    Taniguchi, Hiroyuki; Kondoh, Yasuhiro

    2016-07-01

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

  12. Orbital hemorrhage and eyelid ecchymosis in acute orbital myositis.

    Reifler, D M; Leder, D; Rexford, T

    1989-02-15

    We examined two patients with acute orbital myositis associated with orbital hemorrhage and eyelid ecchymosis. Both patients were young women (aged 22 and 30 years) who had painful proptosis, diplopia, and computed tomographic evidence of single extraocular muscle involvement with spillover of inflammatory edema into the adjacent orbital fat. Patient 1 showed contralateral preseptal eyelid inflammation and did not suffer an orbital hemorrhage until after an episode of vomiting. In Patient 2, the diagnosis of occult orbital varix was initially considered but an orbital exploration and a biopsy specimen showed no vascular anomaly. Both patients were treated successfully with high-dose systemic corticosteroids. Some cases of idiopathic orbital inflammation may be related to preexisting vascular anomalies or orbital phlebitis.

    Brouwers, H. Bart; Joshua N Goldstein

    2011-01-01

    Intracerebral hemorrhage is a devastating disease, and no specific therapy has been proven to reduce mortality in a randomized controlled trial. However, management in a neuroscience intensive care unit does appear to improve outcomes, suggesting that many available therapies do in fact provide benefit. In the acute phase of intracerebral hemorrhage care, strategies aimed at minimizing ongoing bleeding include reversal of anticoagulation and modest blood pressure reduction. In addition, the m...

  14. Preretinal hemorrhage as a presenting sign of idiopathic macular telangiectasia type 2.

    Osher, James M; Sisk, Robert A; Petersen, Michael R

    2015-01-01

    We report three cases of idiopathic macular telangiectasia type 2 with temporally decentered preretinal hemorrhage as the presenting sign. The preretinal blood obscured the telangiectatic vessels such that the diagnosis was only evident by fluorescein angiography of the fellow eyes, which had near-normal vision. The preretinal hemorrhage was associated with Valsalva maneuver in one patient and with type 3 subretinal neovascularization in one patient. We speculate that the vascular dilations in idiopathic macular telangiectasia type 2 may increase patients' susceptibility to rupture and hemorrhage with increased venous pressure. PMID:26300623

  16. Unilateral acute idiopathic maculopathy. 1991.

    Yannuzzi, Lawrence A; Jampol, Lee M; Rabb, Maurice F; Sorenson, John A; Beyrer, Charles; Wilcox, Lloyd M

    2012-02-01

    This is a report of nine patients who experienced sudden, severe, unilateral central vision loss following a flulike illness. Each patient had an exudative detachment of the macula. All patients experienced a spontaneous resolution of the acute macular manifestations with near-complete recovery of vision. A characteristic "bull's-eye" appearance in the macula persisted. The acute manifestations of the disorder did not recur in any of the patients during the period of follow-up. The constellation of findings was suggestive of an inflammatory disease of the retinal pigment epithelium, but a specific causative agent could not be identified. The acute clinical and angiographic features, the natural course, and the residual pigment epithelial derangement were not consistent with any previously described disorder. PMID:22451959

  17. Acute atrial fibrillation during dengue hemorrhagic fever

    Veloso Henrique Horta

    2003-01-01

    Full Text Available Dengue fever is a viral infection transmitted by the mosquito, Aedes aegypti. Cardiac rhythm disorders, such as atrioventricular blocks and ventricular ectopic beats, appear during infection and are attributed to viral myocarditis. However, supraventricular arrhythmias have not been reported. We present a case of acute atrial fibrillation, with a rapid ventricular rate, successfully treated with intravenous amiodarone, in a 62-year-old man with dengue hemorrhagic fever, who had no structural heart disease.

It represents a diagnosis of exclusion. It is necessary to rule out infectious and noninfectious causes of pericardial inflammation, including systemic autoimmune and immune-related disorders, eg, Sjögren’s disease, systemic lupus erythematosus. Since pericarditis may precede diagnosis of these disorders, IRAP diagnosis is often made after a long follow-up. According to the two main pathogenetic theories IRAP may represent an organ-specific autoimmune disease or an autoinflammatory disease (AInfD. The main evidence for autoimmunity in IRAP is provided by the detection of serum antiheart and antiintercalated-disk autoantibodies, and the response to anti-inflammatory or immunosuppressive therapy. The findings of familial forms and of proinflammatory cytokines in the pericardial fluid in IRAP would be in keeping with both organ-specific autoimmune disease and AInfD. In fact, AInfD are genetic disorders characterized by primary dysfunction of the innate immune system, due to mutations of genes involved in the regulation of the inflammatory response, in the absence of antigen specific T cells or autoantibodies. In AInfD there are active disease phases with raised non-cardiac specific inflammatory markers, such as C-reactive protein, as well as symptom-free intervals with possible C-reactive protein normalization. A minority of IRAP patients (6% carry a

  4. Diffuse alveolar hemorrhages and hemorrhagic pleural effusion after thromblytic therapy with streptokinase for acute myocardial infaraction

    Thrombolytic therapy with streptokinase is commonly used in acute myocardial infarction and has markedly reduced morbidity and mortality from this condition. However it can cause various haemorrhagic and immunological complications. we report a patient who developed diffuse pulmonary hemorrhages (PH) and bilateral hemorrhagic pleural effusion after thrombolytic therapy with streptokinase for acute myocardial infarction. This was recognized by a drop of hematocrit,pulmonary infiltrates, hemorrhagic pleural effusion(HPE) and hypoxaemia. The diagnosis was confirmed by demonstration of iron-laden macrophages in bronchoalveolar lavage. The patient required mechanical ventilation and recovered successfully. This combination of PH and HPE following streptokinase therapy's extremely unusual and and has not been reported previously. (author)

  5. The fecal microbiome in dogs with acute diarrhea and idiopathic inflammatory bowel disease.

    Jan S Suchodolski

    Full Text Available BACKGROUND: Recent molecular studies have revealed a highly complex bacterial assembly in the canine intestinal tract. There is mounting evidence that microbes play an important role in the pathogenesis of acute and chronic enteropathies of dogs, including idiopathic inflammatory bowel disease (IBD. The aim of this study was to characterize the bacterial microbiota in dogs with various gastrointestinal disorders. METHODOLOGY/PRINCIPAL FINDINGS: Fecal samples from healthy dogs (n = 32, dogs with acute non-hemorrhagic diarrhea (NHD; n = 12, dogs with acute hemorrhagic diarrhea (AHD; n = 13, and dogs with active (n = 9 and therapeutically controlled idiopathic IBD (n = 10 were analyzed by 454-pyrosequencing of the 16S rRNA gene and qPCR assays. Dogs with acute diarrhea, especially those with AHD, had the most profound alterations in their microbiome, as significant separations were observed on PCoA plots of unweighted Unifrac distances. Dogs with AHD had significant decreases in Blautia, Ruminococcaceae including Faecalibacterium, and Turicibacter spp., and significant increases in genus Sutterella and Clostridium perfringens when compared to healthy dogs. No significant separation on PCoA plots was observed for the dogs with IBD. Faecalibacterium spp. and Fusobacteria were, however, decreased in the dogs with clinically active IBD, but increased during time periods of clinically insignificant IBD, as defined by a clinical IBD activity index (CIBDAI. CONCLUSIONS: Results of this study revealed a bacterial dysbiosis in fecal samples of dogs with various GI disorders. The observed changes in the microbiome differed between acute and chronic disease states. The bacterial groups that were commonly decreased during diarrhea are considered to be important short-chain fatty acid producers and may be important for canine intestinal health. Future studies should correlate these observed phylogenetic differences with functional changes in the intestinal

    To describe the clinical and MRI findings in three children with acute idiopathic myelopathy (AIM). Retrospective review of the clinical presentation, MRI findings and outcome of three patients diagnosed with acute idiopathic transverse myelitis. Of note was the swift onset of symptoms in all patients, without any preceding illness or history of vaccination in two of the patients, and the rapid resolution of symptoms on steroid therapy in all the patients. MRI showed T2-weighted hyperintensity and patchy enhancement with gadolinium, but the extensive cord involvement did not correlate with the severity of presentation or outcome. Our findings do not support that MRI evidence alone of diffuse myelopathy is a predictor of poor outcome in childhood AIM. (orig.)

  12. Acute exacerbations and pulmonary hypertension in advanced idiopathic pulmonary fibrosis.

    Judge, Eoin P

    2012-07-01

    The aim of this study was to evaluate the risk factors for and outcomes of acute exacerbations in patients with advanced idiopathic pulmonary fibrosis (IPF), and to examine the relationship between disease severity and neovascularisation in explanted IPF lung tissue. 55 IPF patients assessed for lung transplantation were divided into acute (n=27) and non-acute exacerbation (n=28) groups. Haemodynamic data was collected at baseline, at the time of acute exacerbation and at lung transplantation. Histological analysis and CD31 immunostaining to quantify microvessel density (MVD) was performed on the explanted lung tissue of 13 transplanted patients. Acute exacerbations were associated with increased mortality (p=0.0015). Pulmonary hypertension (PH) at baseline and acute exacerbations were associated with poor survival (p<0.01). PH at baseline was associated with a significant risk of acute exacerbations (HR 2.217, p=0.041). Neovascularisation (MVD) was significantly increased in areas of cellular fibrosis and significantly decreased in areas of honeycombing. There was a significant inverse correlation between mean pulmonary artery pressure and MVD in areas of honeycombing. Acute exacerbations were associated with significantly increased mortality in patients with advanced IPF. PH was associated with the subsequent development of an acute exacerbation and with poor survival. Neovascularisation was significantly decreased in areas of honeycombing, and was significantly inversely correlated with mean pulmonary arterial pressure in areas of honeycombing.

  17. Diagnosis of acute necrotizing pancreatitis and acute hemorrhagic pancreatitis in 5 severe acute pancreatitis by plain computed tomography

    The diagnosis of acute pancreatitis is still mainly based on the clinical signs and symptoms of patients. In a prospective study of 64 patients with acute pancreatitis, computed tomography (CT) findings were correlated with the clinical types of acute pancreatitis. We were able to correctly diagnose 3 acute necrotizing pancreatitis with autopsy and 2 acute hemorrhagic pancreatitis by plain CT about 48 hours after onset. At present, CT about 48 hours after onset seems to be the most accurate method for the early detection of necrotizing, hemorrhagic and edematous forms of acute pancreatitis. (author)

    Sussman, Eric S; Connolly, E. Sander

    2013-01-01

    Acute ischemic stroke is a devastating disease that is often complicated by hemorrhagic transformation. While significant advances have been made over the past two decades with regard to emergent treatment of AIS, many of the therapeutic options are limited by an increased risk of hemorrhage. Here, we sought to review the rates of hemorrhagic transformation in the major clinical trials of AIS intervention. Since the reviewed clinical trials vary significantly in terms of study design, eligibi...

  3. S-100AND#946; protein as a biomarker in acute hemorrhagic stroke

    Omkar Prasad Baidya

    2014-02-01

    Full Text Available Acute hemorrhagic stroke, a subtype of acute stroke is one of the leading causes of death and disability throughout the world. At present, the diagnosis of acute hemorrhagic stroke is mainly based on Computer Tomography (CT or Magnetic Resonance Imaging (MRI but till now no biomarkers are routinely used in acute hemorrhagic stroke management. This article is a critical and descriptive review on the role of S100β protein as a biomarker in acute hemorrhagic stroke. Plasma S-100β level increases significantly in acute hemorrhagic stroke patients when compared to the normal subjects. Beside, the plasma S-100β can be correlated to the volume of hemorrhage in brain measured by plane CT scan. Plasma S-100β is an useful biomarker in acute hemorrhagic stroke and can be used for estimation of volume of hemorrhage in brain in acute hemorrhagic stroke patients. Thus, S-100β can be useful as an alternative to CT scan/MRI in diagnosis and in taking therapeutic decision in acute hemorrhagic stroke management. [Int J Res Med Sci 2014; 2(1.000: 13-15

    2015-03-01

    Full Text Available Idiopathic isolated cecal necrosis is a clinical problem characterized by right-sided inferior abdominal pain. It is rarely seen, develops due to decreased blood flow to the colon and, imitates acute appendicitis. Its clinical signs are similar to many illnesses causing sensitivity in the right inferior quadrant and, the diagnosis is generally determined during surgery. An 86-year-old male patient presented with the complaints of abdominal pain, trichiniasis, nausea and vomiting. Surgical intervention was decided when physical examination and laboratory results were taken into consideration. After diagnostic laparoscopy, right hemicolectomy was performed because of cecal necrosis. While the mortality and morbidity rates for ischemic bowel disease are high, prognosis for early diagnosed patients with isolated cecal necrosis is better, provided that timely surgical treatment is decided.

    2015-09-01

    We report a case of acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis. A 48-year-old previously healthy male was found dead in his locked apartment. At autopsy he was found to be malnourished, and his lungs showed gross evidence of bilateral pneumonia with abscess formation and bullous emphysema. Multiple petechial hemorrhages were observed in the brain and mainly involved white matter in the cerebral hemispheres including the corpus callosum and internal capsule, as well as the cerebellum, brainstem, and spinal cord. Microscopy of the brain and spinal cord revealed perivenular hemorrhages, central microthrombi in venules with fibrin exudation into the subcortical white matter, and early perivenular demyelination associated with scanty mixed cellular infiltrates. Other microscopic features included widespread diffuse viral myocarditis, extensive suppurative bronchopneumonia, and chronic bronchitis. This case illustrates the death of a man with a rare fatal disease associated with two other potentially lethal diseases. The case also illustrates the importance of a holistic approach when determining the cause of death, especially when there are competing causes of death. PMID:26148811

    2000-04-01

    To evaluate the efficacy and safety of superselective arterial embolization using the microcoil in acute gastrointerstinal hemorrhage. We evaluated 11 of 42 patients who had undergone diagnostic angiography and transcatheter arterial embolization due to acute gastrointestinal hemorrhage and subsequently underwent superselective arterial embolization using the microcoil. Nine were males and two were females, and their age ranged from 33 to 70 (mean, 51) years. The etiologies were bleeding ulcer (n=3D5), pseudoaneurysm from pancreatitis (n=3D3), and postoperative bleeding (n=3D3). The symptoms were melena, hematemesis, and hematochzia, and the critical signs were cecreased hemoglobin and worsening of vital signs. All patients underwent superselective embolization using the microcatheter and microcoil. Bleeding occurred in the gastroduodenal artery (n=3D5), inferior pancreaticoduodenal artery (n=3D2), left gastric artery (n=3D2), right hepatic artery (n=3D1), and ileal branch of the superior mesenteric artery (n=3D1). All cases were treated succesfully, without complications. In one case in which there was bleeding in the right hepatic artery, reembolization with a microcoil was needed because of persistent melena. During follow up, three patients died from complications arising underlying diseases, namely disseminated intravascular coagulopathy, chronic renal failure, and adult resiratory distress syndrome.

  12. Transient electro-oculogram impairment in unilateral acute idiopathic maculopathy.

    Lam, Byron L; Lopez, Pedro F; Dubovy, Sander R; Liu, Mu

    2009-10-01

    Unilateral acute idiopathic maculopathy (UAIM) is a rare distinct entity characterized by acute exudative maculopathy occurring in young persons. The purpose of this case study is to report transient electro-oculogram (EOG) impairment during the acute stage of UAIM. A 16-year-old healthy female with UAIM in the left eye underwent serial visual field, fluorescein angiography, indocyanine green angiography, full-field electroretinogram (ERG), and EOG. Initial visual acuity of the affected left eye was 4/200 with macular subretinal exudates. Indocyanine green angiography disclosed early phase foveal hypocyanescence persisting into late phase along with late phase foci of pinpoint hypocyanescence scattered in the macular and mid-peripheral regions. Standard full-field ERG responses performed 18 days after the onset of symptoms were normal. Standard EOG revealed a marked reduced light-peak to dark-trough amplitude ratio (Arden ratio) of 1.20 left eye (normal >or= 1.7) and a normal ratio of 2.24 right eye. Five weeks later, the left eye improved to 20/50, and the exudative maculopathy resolved with residual irregular foveal hyperpigmentation. Repeat EOG performed 69 days after onset of symptoms showed recovery and normalization of the EOG amplitude ratio of the left eye from 1.20 to 2.54. Transient EOG impairment with a normal full-field ERG may occur during the early stage of UAIM. This finding suggests a more widespread dysfunction of the retinal pigment epithelium in at least some cases of UAIM. PMID:19533190

    2011-08-01

    We studied the relation between changes in pulmonary and systemic hemodynamics to those in the airway resistance, respiratory tissue mechanics, and thoracic gas volume (TGV) following acute hemorrhage and blood reinfusion in rats. Forced oscillation technique was used to measure airway resistance (Raw), respiratory tissue damping, and elastance at baseline and after stepwise 1-ml blood withdrawals up to 5 ml total, followed by stepwise reinfusion up to full restoration. Mean systemic (Pam) and pulmonary arterial pressures and suprarenal aortic blood flow were measured at each step. In supplemental animals, plethysmographic TGV, Pam, and respiratory mechanics measurements were performed. Blood volume loss (BVL) led to proportional decreases in Raw (66.5 ± 8.8 vs. 44.8 ± 9.0 cmH(2)O·s·l(-1) with 5 ml, P TGV significantly increased with acute BVL (3.7 ± 0.2 vs. 4.2 ± 0.2 ml, P = 0.01). Stepwise reinfusions produced opposite changes in the above parameters, with Raw reaching a higher value than baseline (P = 0.001) upon full volume restoration. Both adrenalin (P = 0.015) and noradrenalin levels were elevated (P = 0.010) after 5-ml blood withdrawal. Our data suggest that the decreases in Raw following BVL may be attributed to the following: 1) an increased TGV enhancing airway parenchymal tethering forces; and 2) an increase in circulating catecholamines. The apparent beneficial effect of a reduction in Raw in acute hemorrhagic shock is counteracted by an increase in dead space and the appearance of peripheral mechanical heterogeneities due to de-recruitment of the pulmonary vasculature.

    Background and purpose: vascular erosion is a rare but life-threatening complication after radiotherapy. The authors report on acute arterial bleeding and its therapy following radiotherapy of oropharyngeal tumors. Patients and methods: ten patients with oropharyngeal squamous cell carcinoma of any stage developed foudroyant acute arterial hemorrhage 3-46 months (14.4 {+-} 5.1 months) after primary (5/10) or adjuvant radio(chemo)therapy (R[C]T). Results: all patients had a history of recurrent minor bleeding episodes and showed deep mucosal ulcerations also outside the primary tumor region. A life-threatening arterial hemorrhage appeared in the area of these mucosal defects in the pharyngeal region. Affected vessels were the common carotid artery as well as the internal and the external portion with branches like the ascending pharyngeal and superior thyroid arteries. Treatment consisted of emergency intubation or tracheotomy followed by exposure and package of the pharynx and surgical ligature and/or embolization. 6/10 patients (all hospitalized) survived the episode, however, lethal outcome in 4/10 patients (outpatients) was related to asphyxia as a result of blood aspiration or exsanguination. None of the patients revealed evidence of persistent or recurrent tumor disease as proven by biopsy/autopsy and imaging technique. Conclusion: vascular erosion following primary or adjuvant R(C)T represents a rare and potentially life-threatening complication requiring immediate emergency treatment involving head and neck surgeons, anesthesiologists and neuroradiologists. For patients with oropharyngeal neoplasms treated by R(C)T and showing recurrent bleeding episodes and mucosal ulceration particularly after the acute treatment phase, hospitalization with prophylactic surgical ligature or embolization of affected arteries is recommended.

  16. Idiopathic Hypertrophic Cranial Pachymeningitis Misdiagnosed as Acute Subtentorial Hematoma

    Park, Ik-Seong; Kim, Hoon; Chung, Eun Yong

    2010-01-01

    A case of idiopathic hypertrophic cranial pachymeningitis (IHCP) misdiagnosed as an acute subdural hematoma is reported. A 37-year-old male patient presented with headache following head trauma 2 weeks earlier. Computerized tomography showed a diffuse high-density lesion along the left tentorium and falx cerebri. Initial chest X-rays revealed a small mass in the right upper lobe with right lower pleural thickening, which suggested lung cancer, such as an adenoma or mediastinal metastasis. During conservative treatment under the diagnosis of a subdural hematoma, left cranial nerve palsies were developed (3rd and 6th), followed by scleritis and uveitis involving both eyes. Magnetic resonance imaging (MRI) revealed an unusual tentorium-falx enhancement on gadolinium-enhanced T1-weighted images. Non-specific chronic inflammation of the pachymeninges was noticed on histopathologic examination following an open biopsy. Systemic steroid treatment was initiated, resulting in dramatic improvement of symptoms. A follow-up brain MRI showed total resolution of the lesion 2 months after steroid treatment. IHCP should be included in the differential diagnosis of subtentorial-enhancing lesions. PMID:20856672

  17. Macrophage activation in acute exacerbation of idiopathic pulmonary fibrosis.

    Jonas Christian Schupp

    Full Text Available Acute exacerbation (AE of idiopathic pulmonary fibrosis (IPF is a common cause of disease acceleration in IPF and has a major impact on mortality. The role of macrophage activation in AE of IPF has never been addressed before.We evaluated BAL cell cytokine profiles and BAL differential cell counts in 71 IPF patients w/wo AE and in 20 healthy volunteers. Twelve patients suffered from AE at initial diagnosis while sixteen patients developed AE in the 24 months of follow-up. The levels of IL-1ra, CCL2, CCL17, CCL18, CCL22, TNF-α, IL-1β, CXCL1 and IL-8 spontaneously produced by BAL-cells were analysed by ELISA.In patients with AE, the percentage of BAL neutrophils was significantly increased compared to stable patients. We found an increase in the production rate of the pro-inflammatory cytokines CXCL1 and IL-8 combined with an increase in all tested M2 cytokines by BAL-cells. An increase in CCL18 levels and neutrophil counts during AE was observed in BAL cells from patients from whom serial lavages were obtained. Furthermore, high baseline levels of CCL18 production by BAL cells were significantly predictive for the development of future AE.BAL cell cytokine production levels at acute exacerbation show up-regulation of pro-inflammatory as well as anti-inflammatory/ M2 cytokines. Our data suggest that AE in IPF is not an incidental event but rather driven by cellular mechanisms including M2 macrophage activation.

  18. What are the next breakthroughs in the management of acute intracerebral hemorrhage?

    Toyoda, Kazunori; Koga, Masatoshi; Sato, Shoichiro

    2016-06-01

    The impact of acute therapy for intracerebral hemorrhage is far behind that for acute ischemic stroke. Potential breakthroughs in the management of acute intracerebral hemorrhage are presented. To prevent early hematoma growth, acute blood pressure lowering, emergent hemostatic therapy, and minimally invasive surgery with topical thrombolysis have been attempted. Anti-inflammatory and neuroprotective pharmacotherapies may attenuate perihematomal edema as a surrogate marker for the inflammatory response and improve clinical outcomes after intracerebral hemorrhage. Hyperacute modification of vital parameters, early seizure control, early rehabilitation, and neuroregenerative therapy are other promising strategies in the foreseeable future. PMID:26912534

  19. Methylprednisolone Therapy in Acute Hemorrhagic Edema of Infancy

    Jeyanthini Risikesan

    2014-01-01

    Full Text Available We present a case of an 18-month-old boy who showed severe clinical signs indicative of acute hemorrhagic edema of infancy (AHEI with painful purpuric skin affection primarily of the face and marked edema of the ears. The histological findings were diagnostic for leukocytoclastic vasculitis and thus met the histological criteria for AHEI. Indicative of infection as causative agent for the condition were symptoms of gastroenteritis. High-dose intravenous corticosteroids led to a fast resolution of symptoms and normalization of laboratory parameters. AHEI is usually not described as being very responsive to corticosteroids. The case presented here indicates that severe cases of AHEI can be treated with high-dose intravenous corticosteroids resulting in significant relief and shortening of the symptoms. Clinical followup showed no underlying malignancy or other severe chronic systemic diseases thus confirming earlier reports that AHEI is not associated with such conditions. The differential diagnoses with AHEI are discussed.

  1. Is intervention necessary after a first episode of acute idiopathic pancreatitis?

    Ballinger, A B; Barnes, E.; Alstead, E M; Fairclough, P D

    1996-01-01

    Acute idiopathic pancreatitis is a term used when no underlying cause has been identified on routine investigation. However, more specialised investigations may identify aetiological factors, biliary sludge and sphincter of Oddi dysfunction for example, in 38-72% of patients with recurrent episodes. Treatment of these abnormalities may prevent further episodes of pancreatitis. The aim of this study was to follow up and determine the outcome in patients with a first episode of idiopathic pancr...

  2. Surgical strategy for cerebral arteriovenous malformation with acute hemorrhage

    2007-01-01

    BACKGROUND: Presently, there have been craniocerebral operation, interventional embolization,stereotactic radiotherapy and other methods in treating cerebral arteriovenous malformation (AVM).However, the standard of different therapeutic regimens of cerebral AVM at the acute stage of hemorrhage has not been completely identified.OBJECTIVE: To observe the clinical characteristics and therapeutic effects of AVM at the acute stage of hemorrhage in patients, and to analyze corresponding therapeutic strategies.DESIGN: Non-randomized clinical observation.SETTING: Department of Neurosurgery, Foshan First People's Hospital, Sun Yat-sen University.PARTICIPANTS: Forty-six patients with cerebral AVM complicated by hemorrhage admitted to Department of Neurosurgery, Foshan First People's Hospital between January 1999 and December 2006,were involved in this study. All the patients were confirmed as cerebral AVM complicated by hemorrhage by brain angiography or/and postoperational pathology. The involved patients, 32 males and 14 females,averaged 25 years old, ranging from 6 to 62 years. Informed consents of therapeutic items were obtained from the relatives of all the patients.METHODS: ①On admission, skull CT and brain angiography were conducted in the involved subjects. ②The therapeutic method was confirmed according to the consciousness, hematoma region, hematoma volume,imageological results following comprehensive analysis: DSA examination was permitted to identify the size and position of abnormal vessel mass, and the distribution of feeding artery and draining vein. Craniocerebral operation was carried out as early as possible in patients with severe or progressive conscious disturbance, in which most of hematoma with obvious occupied effect or cerebral hernia was located in lobe of brain. The primary thing was to clean intracerebral hematoma for in time decompression. According to different situations, corresponding therapeutic measures were used for resecting abnormal

  3. Cerebral CT angiography in the diagnosis of acute subarachnoid hemorrhage

    Purpose: To evaluate the usefulness of CT angiography (CTA) in the detection of intracranial aneurysms in patients with acute subarachnoid hemorrhage (SAH). Material and Methods: In 53 patients with nontraumatic SAH a helical contrast-enhanced CTA was performed. CTA data were reconstructed with maximum intensity projection (MIP). Each patient underwent selective arteriography of the cerebral vessels (as the gold standard). CTA (axial images and MIP reconstructions) and arteriography were evaluated separately and their diagnostic information was compared. Results: In 14 of the 53 patients neither CTA nor angiography showed a vascular malformation. In the remaining 39 patients, angiography demonstrated a total of 51 aneurysms ranging in size from 3 mm to 16 mm. CTA missed one of these aneurysms, which was located at the internal carotid artery. 3-D CT reconstruction was slightly superior to arteriography in the demonstration of the neck, shape and direction of the aneurysms. Partial thrombosis of 3 aneurysms was demonstrated only by CTA. Conclusion: Although CTA cannot replace cerebral arteriography in the diagnostic work-up of acute SAH, it proved to be helpful in demonstrating the topographic anatomy of cerebral aneurysms and surrounding structures.

  6. Relation between reperfusion and hemorrhagic transformation in acute ischemic stroke

    Intravenous recombinant tissue plasminogen activator (IV-rtPA) is given in acute ischemic stroke patients to achieve reperfusion. Hemorrhagic transformation (HT) is a serious complication of IV-rtPA treatment and related to blood-brain barrier (BBB) injury. It is unclear whether HT occurs secondary to reperfusion in combination with ischemic BBB injury or is caused by the negative effect of IV-rtPA on BBB integrity. The aim of this study was to establish the association between reperfusion and the occurrence of HT. From the DUST study, patients were selected with admission and follow-up non-contrast CT (NCCT) and CT perfusion (CTP) imaging, and a perfusion deficit in the middle cerebral artery territory on admission. Reperfusion was categorized qualitatively as reperfusion or no-reperfusion by visual comparison of admission and follow-up CTP. Occurrence of HT was assessed on follow-up NCCT. The association between reperfusion and occurrence of HT on follow-up was estimated by calculating odds ratios (ORs) and 95 % confidence intervals (CIs) with additional stratification for IV-rtPA treatment. Inclusion criteria were met in 299 patients. There was no significant association between reperfusion and HT (OR 1.2 95%CI 0.5-3.1). In patients treated with IV-rtPA (n = 203), the OR was 1.3 (95%CI 0.4-4.0), and in patients not treated with IV-rtPA (n = 96), the OR was 0.8 (95%CI 0.1-4.5). HT occurred in 14 % of the IV-rtPA patients and in 7 % of patients without IV-rtPA (95%CI of difference -1 to 14 %). Our results suggest that the increased risk of HT after acute ischemic stroke treatment is not dependent on the reperfusion status. (orig.)

  7. Prevalence of superficial siderosis following singular, acute aneurysmal subarachnoid hemorrhage

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

    Intravenous recombinant tissue plasminogen activator (IV-rtPA) is given in acute ischemic stroke patients to achieve reperfusion. Hemorrhagic transformation (HT) is a serious complication of IV-rtPA treatment and related to blood-brain barrier (BBB) injury. It is unclear whether HT occurs secondary to reperfusion in combination with ischemic BBB injury or is caused by the negative effect of IV-rtPA on BBB integrity. The aim of this study was to establish the association between reperfusion and the occurrence of HT. From the DUST study, patients were selected with admission and follow-up non-contrast CT (NCCT) and CT perfusion (CTP) imaging, and a perfusion deficit in the middle cerebral artery territory on admission. Reperfusion was categorized qualitatively as reperfusion or no-reperfusion by visual comparison of admission and follow-up CTP. Occurrence of HT was assessed on follow-up NCCT. The association between reperfusion and occurrence of HT on follow-up was estimated by calculating odds ratios (ORs) and 95 % confidence intervals (CIs) with additional stratification for IV-rtPA treatment. Inclusion criteria were met in 299 patients. There was no significant association between reperfusion and HT (OR 1.2 95%CI 0.5-3.1). In patients treated with IV-rtPA (n = 203), the OR was 1.3 (95%CI 0.4-4.0), and in patients not treated with IV-rtPA (n = 96), the OR was 0.8 (95%CI 0.1-4.5). HT occurred in 14 % of the IV-rtPA patients and in 7 % of patients without IV-rtPA (95%CI of difference -1 to 14 %). Our results suggest that the increased risk of HT after acute ischemic stroke treatment is not dependent on the reperfusion status. (orig.)

  9. Detection of acute cerebral hemorrhage in rabbits by magnetic induction

    Acute cerebral hemorrhage (ACH) is an important clinical problem that is often monitored and studied with expensive devices such as computed tomography, magnetic resonance imaging, and positron emission tomography. These devices are not readily available in economically underdeveloped regions of the world, emergency departments, and emergency zones. We have developed a less expensive tool for non-contact monitoring of ACH. The system measures the magnetic induction phase shift (MIPS) between the electromagnetic signals on two coils. ACH was induced in 6 experimental rabbits and edema was induced in 4 control rabbits by stereotactic methods, and their intracranial pressure and heart rate were monitored for 1 h. Signals were continuously monitored for up to 1 h at an exciting frequency of 10.7 MHz. Autologous blood was administered to the experimental group, and saline to the control group (1 to 3 mL) by injection of 1-mL every 5 min. The results showed a significant increase in MIPS as a function of the injection volume, but the heart rate was stable. In the experimental (ACH) group, there was a statistically significant positive correlation of the intracranial pressure and MIPS. The change of MIPS was greater in the ACH group than in the control group. This high-sensitivity system could detect a 1-mL change in blood volume. The MIPS was significantly related to the intracranial pressure. This observation suggests that the method could be valuable for detecting early warning signs in emergency medicine and critical care units

    To compare the diffusion characteristics of idiopathic acute transverse myelitis (ATM) and acute spinal cord infarction (SCI). Diffusion-weighted images (DWI) and an apparent diffusion coefficient (ADC) map were prospectively obtained from patients diagnosed with myelopathy between February 2006 and April 2009. Inclusion criteria included 1) the presence of an intramedullary T2-high signal intensity and 2) a final diagnosis of idiopathic ATM or SCI established by one neurologist. In total, 13 patients (M : F = 8 : 5; mean age, 39.5 years; range, 29-50 years) with idiopathic ATM and seven patients (M : F = 2 : 5; mean age, 58 years; range, 48-75 years) with SCI were included in this study. Two radiologists evaluated the DWIs and ADC map in consensus. The extent of the cord signal change was also evaluated on T2-weighted sagittal images. Among the 16 patients with ATM, 14 patients showed iso-signal on an ADC map, but one case showed restricted diffusion and another showed increased diffusion on the ADC map. Among the seven patients with SCI, five patients showed restricted diffusion. Idiopathic ATM usually does not demonstrate restricted diffusion, which can be a clue to differentiate it from SCI. However, idiopathic ATM with larger segment involvement can show focal diffusion restriction.

    Acute recurrent pancreatitis (ARP) is defined as more than two attacks of acute pancreatitis with complete or almost complete resolution of symptoms and signs of pancreatitis between episodes. The initial evaluation fails to detect the cause of ARP in 10%–30% of patients, whose condition is classified as idiopathic ARP. Endoscopic ultrasound (EUS) has gained increasing attention as a useful imaging modality for the pancreas and the extrahepatic biliary tree. The close proximity of the pancrea...

    2010-01-01

    Full Text Available Midbrain hemorrhage causing isolated fourth nerve palsy is extremely rare. Idiopathic, traumatic and congenital abnormalities are the most common causes of fourth nerve palsy. We report acute isolated fourth nerve palsy in an 18-year-old lady due to a midbrain hemorrhage probably due to a midbrain cavernoma. The case highlights the need for neuroimaging in selected cases of isolated trochlear nerve palsy.

  16. Investigation on the clinical practice of transcatheter embolization for acute gastrointestinal hemorrhage

    Objective: To study the tactics, methods and relevant factors of transcatheter embolization for acute gastrointestinal hemorrhage. Methods: Fifteen patients with acute gastrointestinal hemorrhage were embolized by one of the methods of Polyvinyl Alcohol (PVA), gelfoam or metal coils. Four of the fifteen patients were upper gastrointestinal hemorrhage, the other cases were lower gastrointestinal hemorrhage which were embolized using coaxial microcatheter. Results: Fourteen of the fifteen patients were treated successfully by these methods. There were total 17 times of embolization for 16 parts, the success rate reached 94. 1%. The other one revealed an infarction of intestine after the embolization and was cured by resection. One of the fifteen patients appeared a recurrent hemorrhage 3 months later, and confirmed to be a hemangiolymphangioma. Two patients with malignant tumor were operated upon selectively. The other patient of intestinal hemorrhage was embolized successfully by using a metal coil after shock. Leiomyoma complicated with large area of bleeding was finally proven by operation. Conclusions: Transcatheter embolization for acute massive gastrointestinal hemorrhage is safe and efficient under different choice of methods. The key of success is the right selection of embolized target artery and dosage of emboli

  17. Review of Elephant Endotheliotropic Herpesviruses and Acute Hemorrhagic Disease.

    Long, Simon Y; Latimer, Erin M; Hayward, Gary S

    2016-02-24

    More than 100 young captive and wild Asian elephants are known to have died from a rapid-onset, acute hemorrhagic disease caused primarily by multiple distinct strains of two closely related chimeric variants of a novel herpesvirus species designated elephant endotheliotropic herpesvirus (EEHV1A and EEHV1B). These and two other species of Probosciviruses (EEHV4 and EEHV5) are evidently ancient and likely nearly ubiquitous asymptomatic infections of adult Asian elephants worldwide that are occasionally shed in trunk wash secretions. Although only a handful of similar cases have been observed in African elephants, they also have proved to harbor their own multiple and distinct species of Probosciviruses-EEHV2, EEHV3, EEHV6, and EEHV7-found in lung and skin nodules or saliva. For reasons that are not yet understood, approximately 20% of Asian elephant calves appear to be susceptible to the disease when primary infections are not controlled by normal innate cellular and humoral immune responses. Sensitive specific polymerase chain reaction (PCR) DNA blood tests have been developed, routine monitoring has been established, the complete large DNA genomes of each of the four Asian EEHV species have now been sequenced, and PCR gene subtyping has provided unambiguous evidence that this is a sporadic rather than epidemic disease that it is not being spread among zoos or other elephant housing facilities. Nevertheless, researchers have not yet been able to propagate EEHV in cell culture, determine whether or not human antiherpesvirus drugs are effective inhibitors, or develop serology assays that can distinguish between antibodies against the multiple different EEHV species.

    Objective: To assess the risk factors leading to medical complications of hemorrhagic stroke. Methods: We conducted an observational study in neurology, emergency and general medicine wards at a tertiary care teaching hospital in Kadapa. We recruited hemorrhagic stroke patients, and excluded the patients have evidence of trauma or brain tumor as the cause of hemorrhage. We observed the subjects throughout their hospital stay to assess the risk factors and complications. Results: During period of 12 months, 288 subjects included in the study, 89% of them identified at least 1 prespecified risk factor for their admission in hospital and 75% of them experienced at least 1 prespecified complication during their stay in hospital. Around 47% of subjects deceased, among which 64% were females. Conclusions: Our study has assessed that hypertension followed by diabetes mellitus are the major risk factors for medical complications of hemorrhagic stroke. Female mortality rate was more when compared to males.

    Diabetes ketoacidosis (DKA) is one of the common complications of type I insulin-dependent diabetes mellitus. Neurological deterioration during an episode of DKA is usually assumed to be caused by cerebral edema and cerebral vascular accidents. However, hemorrhagic stroke is a very rare complication of juvenile DKA. We describe a girl who had newly diagnosed insulin-dependent diabetes mellitus with juvenile DKA developed intracerebral hemorrhage. PMID:17629647

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

    2015-02-01

    Full Text Available Omental torsion leading on to omental infarction is an unusual cause of acute abdominal pain in adults. Often the condition mimics common causes of acute abdomen like acute cholecystitis, acute appendicitis or acute pancreatitis. A review of literature reveals that this enigmatic condition has been managed both non - operatively and by surgery in the past. We report the case of a 46 - year - old man who presented with a 4 - day history of severe right - sided abdominal pain mimicking acute cholecystitis. Abdominal CT scan revealed a right upper quadrant mass with a whirl - like appearance, suspicious for omental infarction. He was started on conservative management with analgesics and antibiotics. He improved symptomatically and was discharged

    2013-01-01

    Little is known about the pathophysiology of acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF). Heat shock protein 47 (HSP47), a collagen-specific molecular chaperone, is essential for biosynthesis and secretion of collagen molecules. Previous studies in experimental animal fibrosis models have shown that downregulation of HSP47 expression reduces collagen production and diminishes fibrosis progression. In this study, serum HSP47 levels were evaluated to elucidate pathogenic diff...

  9. A case of acute exacerbation of idiopathic pulmonary fibrosis after proton beam therapy for non-small cell lung cancer

    There have been no reports describing acute exacerbations of idiopathic pulmonary fibrosis after particle radiotherapy for non-small cell lung cancer. The present study describes the case of a 76-year-old Japanese man with squamous cell carcinoma of the lung that relapsed in the left upper lobe 1 year after right upper lobectomy. He had been treated with oral prednisolone 20 mg/day every 2 days for idiopathic pulmonary fibrosis, and the relapsed lung cancer was treated by proton beam therapy, which was expected to cause the least adverse effects on the idiopathic pulmonary fibrosis. Fifteen days after the initiation of proton beam therapy, the idiopathic pulmonary fibrosis exacerbated, centered on the left upper lobe, for which intensive steroid therapy was given. About 3 months later, the acute exacerbation of idiopathic pulmonary fibrosis had improved, and the relapsed lung cancer became undetectable. Clinicians should be aware that an acute exacerbation of idiopathic pulmonary fibrosis may occur even in proton beam therapy, although proton beam therapy appears to be an effective treatment option for patients with idiopathic pulmonary fibrosis.

  10. MRI in predication of early hemorrhagic transformation after acute stroke

    Objective: To investigate the relationship among early parenchymal enhancement, post- gadolinium (Gd) hyperintense middle cerebral artery (HMCA), and subsequent hemorrhagic transformation (HT) in patients with hyperacute ischemic stroke. Methods: Twenty-four consecutive patients with ischemic stroke who underwent MRI within 6 h [(4.3±1.4) h] of symptom onset were retrospectively reviewed. All of these patients underwent at least one follow-up MRI or non-enhanced CT study at 2 to 7 days. Post-Gd T1WI were analyzed for parenchymal enhancement and hyperintense MCA. Gradient echo MRI and CT were used for assessment of HT. Results: Ten patients developed HT on follow-up imaging (hemorrhagic group). Early parenchymal enhancement was found in 6 patients with HT (P1WI after Gd-DTPA administration are independent predictors of subsequent HT. (authors)

  11. Atypical presentation of acute idiopathic megacolon in a 14-year-old patient

    B. Barakat

    2012-12-01

    Full Text Available In clinical practice the term “megacolon” is used to indicate a marked dilatation of the cecum and the sigmoid colon (>12 and 6.5 cm, respectively (1. From a clinical standpoint, a megacolon can be classified as chronic or acute depending on its clinical presentation. Chronic megacolon typically refers to a congenital disorder in which the enteric nervous system (ENS supplying the colon does not develop properly, thereby leaving the distal segments of the viscus without myenteric and submucosal ganglia (i.e. Hirschsprung’s disease (2. Other cases of non-aganglionic chronic megacolon can be secondary to variety of conditions such as Chagas’ disease and neurodegenerative diseases (e.g. Parkinson’s and Alzheimer’s diseases, leading to or associated with ENS abnormalities (3. The acute form of megacolon, also referred to as Ogilvie’s syndrome, is characterized by a predominant involvement of the cecum and right colon usually affecting elderly patients undergoing surgery (e.g. orthopedic procedures or taking medications altering gut motility (e.g. opioids or antidepressants (4. Some forms of acute megacolon, however, can be idiopathic in origin since no underlying etiology can be identified. Patients with acute idiopathic megacolon usually have a longstanding history of constipation, often accompanied by laxative abuse, and their clinical presentation is characterized by abdominal distension and severe pain with radiological evidence of stool impacted in the colon and rectum (1, 4. The case herein reported represents an unusual form of acute idiopathic megacolon characterized by massive descending and sigmoid colon distension complicated with a volvulus in a 14-year-old boy with no Hirschsprung’s disease. In addition, just to increase the peculiarity of this case report, the patient had an unremarkable clinical record, and never suffered from chronic constipation in the past.

  15. Idiopathic thrombocytopenic purpura following successful treatment of acute lymphoblastic leukemia.

    Tannir, N M; Kantarjian, H

    2001-03-01

    Thrombocytopenia is common in patients with acute lymphocytic leukemia (ALL) at diagnosis. It is a universal side effect of dose-intensive regimens employed in the treatment of adult ALL. In patients with ALL who achieve remission, thrombocytopenia frequently indicates relapse. We report three adult patients successfully treated for ALL who developed thrombocytopenia and were found to have immune-mediated thrombocytopenia (ITP). Possible pathophysiologic mechanisms underlying the association of ALL and ITP are discussed. PMID:11342378

  18. Acute Onset of Intracerebral Hemorrhage due to Autonomic Dysreflexia.

    Eker, Amber; Yigitoglu, Pembe Hare; Ipekdal, H Ilker; Tosun, Aliye

    2014-05-01

    Autonomic dysreflexia is a clinical emergency syndrome of uncontrolled sympathetic output that can occur in patients who have a history of spinal cord injury. Despite its frequency in spinal cord injury patients, central nervous system complications are very rare. We report a man with traumatic high level incomplete spinal cord injury who suffered hypertensive right thalamic hemorrhage secondary to an episode of autonomic dysreflexia.

    The effect of acute cardiac nerve blockade (CNB) on the increases in plasma renin activity (PRA), arginine vasopressin (AVP), and cortisol in response to a 30 ml/kg hemorrhage was determined in conscious dogs (n = 9). Procaine was infused into the pericardial space to produce acute reversible CNB, or saline was infused in the control hemorrhage. Blood was removed from the inferior vena cava at a rate of 1 ml.kg-1.min-1. In the control hemorrhage, plasma AVP increased from 1.8 +/- 0.3 to 219 +/- 66 pg/ml, PRA increased from 0.63 +/- 0.20 to 3.08 +/- 0.91 ng angiotensin I (ANG I).ml-1.3 h-1, and cortisol increased from 1.4 +/- 0.2 to 4.0 +/- 0.7 micrograms/dl. When the hemorrhage was repeated during acute CNB, plasma AVP increased from 2.8 +/- 1.6 to 185 +/- 59 pg/ml, PRA increased from 0.44 +/- 0.14 to 2.24 +/- 0.27 ng ANG I.ml-1.3 h-1, and cortisol increased from 1.9 +/- 0.3 to 5.4 +/- 0.6 micrograms/dl, and none of the increases differed significantly from the responses during the control hemorrhage. Left atrial pressure fell significantly after removal of 6 ml/kg of blood, but mean arterial pressure was maintained at control levels until blood loss reached 20 ml/kg during pericardial infusion of either saline or procaine. The declines in MAP at the 30 ml/kg level of hemorrhage in both treatments were similar. These results demonstrate that acutely blocking input from cardiac receptors does not reduce the increases in plasma AVP, cortisol, and PRA in response to a 30 ml/kg hemorrhage. The results of this study do not support the hypothesis that input from cardiac receptors is required for a normal AVP response to hemorrhage and suggest that other receptors, presumably arterial baroreceptors, can stimulate AVP and cortisol secretion in the absence of signals from the heart.

  20. Acute Paraplegia as a Result of Hemorrhagic Spinal Ependymoma Masked by Spinal Anesthesia: Case Report and Review of Literature

    Lee, Sang-Hyo; Jeun, Sin-Soo

    2016-01-01

    Ependymomas are the most common intramedullary spinal cord tumors in adults. Although a hemorrhage within spinal ependymoma on imaging studies is not uncommon, it has rarely been reported to bea cause of acute neurological deficit. In the present report, we describe a case of a 24-year-old female patient who developed acute paraplegia as a result of hemorrhagic spinal ependymoma immediately after a cesarean delivery under spinal regional anesthesia. We review the literature of hemorrhagic spinal ependymomas presenting with acute neurological deficit and discuss the most appropriate treatment for a good neurological recovery. PMID:27195260

    2011-01-01

    After injury the acute-phase response of the organism activates mechanisms which imply the release of cytokines, stress hormones, and mediators of pain and inflammation. The main function of the acutephase response is to hinder further damage of the injured tissue by activating reparative processes. The increase in the concentration of acute phase proteins and the concurrent decrease in albumins and prealbumins indicate that there is a strong link between t...

  2. Comparison of histological lesions in mink with acute hemorrhagic pneumonia associated with Pseudomonas aeruginosa or Escherichia coli

    Salomonsen, Charlotte Mark; Boye, Mette; Høiby, Niels; Jensen, Trine H.; Hammer, Anne Sofie

    2013-01-01

    Hemorrhagic pneumonia can be a major cause of mortality in farmed mink in the fall. In its classic form, hemorrhagic pneumonia is caused by the bacterium Pseudomonas aeruginosa. In recent years, however, outbreaks of this type of pneumonia that are associated with hemolytic Escherichia coli have also occurred in farmed mink. The purpose of this study was to compare histological lesions of acute hemorrhagic pneumonia associated with both P. aeruginosa and E. coli in mink, including a descripti...

  3. Acute idiopathic blue fingers: a young man with Achenbach's syndrome.

    Takeuchi, Hidemi; Uchida, Haruhito Adam; Okuyama, Yuka; Wada, Jun

    2016-01-01

    We report a case of a 20-year-old man presenting with acute painful blue fingers. All physical findings, including an Allen test, were normal, and systematic symptoms frequently seen in collagen diseases were absent. Although we performed a wide variety of investigations including medical imaging, no specific abnormal findings were observed. Skin biopsy pathology was an important reference. The patient's symptoms gradually improved and were completely resolved without specific treatment. Based on the clinical presentation and course, we gave a diagnosis of Achenbach's syndrome, developed in a young male. Achenbach's syndrome is rare, but still may be encountered in clinical practice. The symptoms can be startling to the patient, eliciting fear of something terrible when, in fact, the syndrome is relatively benign and has a good prognosis. Recognising this disease quickly after presentation helps to eliminate the anxiety of the patient, as well as reducing excessively invasive investigations. We present a case report to enlighten Achenbach's syndrome. PMID:27090544

  4. Sphincter of Oddi dysfunction and bile duct microlithiasis in acute idiopathic pancreatitis

    Grace H Elta

    2008-01-01

    Although there are numerous causes of acute pancreatitis,an etiology cannot always be found.Two potential etiologies,microlithiasis and sphincter of Oddi dysfunction,are discussed in this review.Gallbladder microlithiasis,missed on transcutaneous ultrasound,is reported as the cause of idiopathic acute pancreatitis in a wide frequency range of 6%-80%.The best diagnostic technique for gallbladder microlithiasis is endoscopic ultrasound although biliary crystal analysis and empiric cholecystectomy remain as reasonable options.In contrast,in patients who are post-cholecystectomy,bile duct microlithiasis does not appear to have a role in the pathogenesis of acute pancreatitis.Sphincter of Oddi dysfunction is present in 30%-65% of patientswith idiopathic acute recurrent pancreatitis in whom other diagnoses have been excluded.It is unclear if this sphincter dysfunction was the original etiology of the first episode of pancreatitis although it appears to have a causative role in recurring episodes since sphincter ablation decreases the frequency of recurrent attacks.Unfortunately,this conclusion is primarily based on small retrospective case series;larger prospective studies of the outcome of pancreatic sphincterotomy for SOD-associated acute pancreatitis are sorely needed.Another problem with this diagnosis and its treatment is the concern over potential procedure related complications from endoscopic retrograde cholangiopancreatography (ERCP),manometry and pancreatic sphincterotomy.For these reasons,patients should have recurrent acute pancreatitis,not a single episode,and have a careful informed consent before assessment of the sphincter of Oddi is undertaken.

  5. Intracerebral Hemorrhage; towards physiological imaging of hemorrhage risk in acute and chronic bleeding.

    Raphael eJakubovic

    2012-05-01

    Full Text Available Despite improvements in management and prevention of intracerebral hemorrhage (ICH, there has been little improvement in mortality over the last 30 years. Hematoma expansion, primarily during the first few hours is highly predictive of neurological deterioration, poor functional outcome and mortality. For each 10% increase in ICH size, there is a 5% increase in mortality and an additional 16% chance of poorer functional outcome. As such, both the identification and prevention of hematoma expansion are attractive therapeutic targets in ICH. Previous studies suggest that contrast extravasation seen on CT Angiography (CTA, MRI, and digital subtraction angiography correlates with hematoma growth, indicating ongoing bleeding. Contrast extravasation on the arterial phase of a CTA has been coined the CTA Spot Sign. These easily identifiable foci of contrast enhancement have been identified as independent predictors of hematoma growth, mortality and clinical outcome in primary ICH. The Spot Sign score, developed to stratify risk of hematoma expansion, has shown high inter-observer agreement. Post-contrast leakage or delayed CTA Spot Sign, on post contrast CT following CTA or delayed CTA respectively are seen in an additional ~8% of patients and explain apparently false negative observations on early CTA imaging in patients subsequently undergoing hematoma expansion. CT perfusion provides an opportunity to acquire dynamic imaging and has been shown to quantify rates of contrast extravasation. Intravenous recombinant factor VIIa(rFVIIa within 4 hours of ICH onset has been shown to significantly reduce hematoma growth. However, clinical efficacy has yet to be proven. There is compelling evidence that cerebral amyloid angiopathy (CAA may precede the radiographic evidence of vascular disease and as such contribute to microbleeding. The interplay between microbleeding, CAA,CTA Spot Sign and genetic composition (ApoE genotype may be crucial in developing a

    Full Text Available Background Various indices have been raised as predictors of activity and severity of juvenile idiopathic arthritis. Objectives This study was conducted to investigate the changes of platelet indices in acute phase and two months after treatment in these patients. Patients and Methods In a cohort study, platelet count, mean platelet volume (MPV, platelet distribution width (PDW, plateletcrit (PCT were evaluated in children referred to children’s medical center, Tehran due to juvenile idiopathic arthritis from March 2013 to March 2014 during the acute phase and two months after standard treatment. The statistical data were analyzed by SPSS 19 software, and the significance level was set as P < 0.05. Results In this study, 55 children (24 boys and 31 girls with mean ± SD age of 7.50 ± 3.35 years were studied. The mean ± SD value of platelet count was 441872.7 ± 151836.9 in the acute phase and reached 395418.2 ± 119601.6 two months after treatment (P = 0.01. The mean ± SD PCT in the acute phase of various subtypes of the disease was 0.32 ± 0.11, which reached 0.29 ± 0.10 after treatment (P = 0.09. However, the PDW range in different subtypes of the disease reached 13.4 ± 8.0 from 13.9 ± 2.9 and MPV reached 8.7 ± 0.9 from 8.8 ± 1.1 after treatment, but they were not significantly different from the results in the acute phase (P = 0.5. Conclusions Platelet count is one of the most remarkable indices in JIA. Evaluation of PCT can also help determine the severity of the inflammatory process in the follow-up and treatment process.

  7. Acute exacerbation of idiopathic pulmonary fibrosis as the initial presentation of the disease

    K. Sakamoto

    2009-06-01

    Full Text Available The clinical course of patients with idiopathic pulmonary fibrosis (IPF is generally marked by a decline in pulmonary function over time, although recently there is increasing recognition that fatal deterioration from acute exacerbation can occur at any stage. The patient described in the present case study was a 65-yr-old male who presented with exertional dyspnoea and fever of 2 weeks' duration. He had no history of chronic lung disease or physiological or radiological hallmarks of pre-existing disease. He underwent surgical lung biopsy and the histological examination showed a background pattern of usual interstitial pneumonia (UIP with a pattern of focal acute diffuse alveolar damage (DAD in the area where normal lung architecture was preserved. It is notable that the pathological diagnosis of this rapidly progressive interstitial pneumonia was DAD on UIP, which is typically seen in acute exacerbations of IPF. Unusual findings on high-resolution computed tomography scan were also noted. We presume that in this case acute exacerbation developed in the very early course of IPF. Given the possibility that similar cases may have arisen among patients diagnosed with acute interstitial pneumonia or acute respiratory distress syndrome, the histopathology of rapidly progressive interstitial pneumonia may need to be revisited.

    Minimal information is available on the incidence of Crimean–Congo hemorrhagic fever (CCHF) virus and hantavirus infections in Georgia. From 2008 to 2011, 537 patients with fever ≥ 38°C for ≥ 48 hours without a diagnosis were enrolled into a sentinel surveillance study to investigate the incidence of nine pathogens, including CCHF virus and hantavirus. Of 14 patients with a hemorrhagic fever syndrome, 3 patients tested positive for CCHF virus immunoglobulin M (IgM) antibodies. Two of the patients enrolled in the study had acute renal failure. These 2 of 537 enrolled patients were the only patients in the study positive for hantavirus IgM antibodies. These results suggest that CCHF virus and hantavirus are contributing causes of acute febrile syndromes of infectious origin in Georgia. These findings support introduction of critical diagnostic approaches and confirm the need for additional surveillance in Georgia. PMID:24891463

  9. Embolization of the Vasa Recta in Acute Lower Gastrointestinal Hemorrhage: A Report of Five Cases

    Purpose: To present our preliminary experience in embolization of the vasa recta in acute gastrointestinal hemorrhage. Methods: In four of five patients with acute gastrointestinal hemorrhage superselective embolization of the vasa recta was performed. In one patient in whom superselective catheterization of the bleeding vas rectum was technically impossible, the origin of this vessel was embolized at the level of the terminal arcade. The following embolization materials were used: microcoils and polyvinyl alcohol particles (355-500 μm), n= 2; microcoils only, n= 2; Gelfoam particles, n1. Results: Bleeding was found in two patients in the small bowel (jejunum and ileum) and in three patients in the colon. Immediate hemostasis was achieved in all patients. No signs of ischemia or infarction were observed after intervention. Conclusions: Superselective embolization of the vasa recta proved efficient and safe in our small patient group. Advantages of this technique are reduction of the embolized area to a minimum and direct control of hemostasis

    2015-01-01

    Full Text Available Background. Frequency and impact of medical complications on short-term mortality in young patients with intracerebral hemorrhage (ICH have gone unstudied. Methods. We reviewed data of all first-ever nontraumatic ICH patients between 16 and 49 years of age treated in our hospital between January 2000 and March 2010 to identify medical complications suffered. Logistic regression adjusted for known ICH prognosticators was used to identify medical complications associated with mortality. Results. Among the 325 eligible patients (59% males, median age 42 [interquartile range 34–47] years, infections were discovered in 90 (28%, venous thrombotic events in 13 (4%, cardiac complications in 4 (1%, renal failure in 59 (18%, hypoglycemia in 15 (5%, hyperglycemia in 165 (51%, hyponatremia in 146 (45%, hypernatremia in 91 (28%, hypopotassemia in 104 (32%, and hyperpotassemia in 27 (8%. Adjusted for known ICH prognosticators and diabetes, the only independent complication associated with 3-month mortality was hyperglycemia (plasma glucose >8.0 mmol/L (odds ratio: 5.90, 95% confidence interval: 2.25–15.48, P<0.001. Three or more separate complications suffered also associated with increased mortality (7.76, 1.42–42.49, P=0.018. Conclusions. Hyperglycemia is a frequent complication of ICH in young adults and is independently associated with increased mortality. However, multiple separate complications increase mortality even further.

    2009-01-01

    Traumatic injury/hemorrhagic shock (T/HS) elicits an acute inflammatory response that may result in death. Inflammation describes a coordinated series of molecular, cellular, tissue, organ, and systemic responses that drive the pathology of various diseases including T/HS and traumatic brain injury (TBI). Inflammation is a finely tuned, dynamic, highly-regulated process that is not inherently detrimental, but rather required for immune surveillance, optimal post-injury tissue repair, and rege...

    2015-07-01

    Full Text Available This paper aims to observe the curative effect of monosialotetrahexosylganglioside combined with Xingnaojing injection on acute cerebral hemorrhage. A total of 120 cases with acute cerebral hemorrhage were treated with Xingnaojing injection monotherapy (control group, N = 60 or monosialotetrahexosylganglioside combined with Xingnaojing injection (combined treatment group, N = 60. Bleeding amount and National Institutes of Health Stroke Scale (NIHSS scores of 2 groups were both significantly reduced on the 21th day after treatment (P = 0.000, for all, but bleeding amount and NIHSS scores in combined treatment group were significantly lower than those in control group (P = 0.000, for all. After 21 d treatment, total effective rate of combined treatment group was 86.67% (52/60, which was significantly higher than that of control group [66.67% (40/60; χ2 = 1.493, P = 0.024]. For patients with acute cerebral hemorrhage, monosialotetrahexosylganglioside combined with Xingnaojing injection can significantly improve the neurological function. DOI: 10.3969/j.issn.1672-6731.2015.07.014

  15. Analysis of multi-factors affecting symptomatic intracranial hemorrhage in intraarterial thrombolysis with urokinase for acute ischemic stroke

    Objective: To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods: From February 1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results: Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio, 1.068 ; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions: Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.

    2013-01-01

    Full Text Available Idiopathic acute eosinophilic pneumonia (IAEP, characterized by acute febrile respiratory failure associated with diffuse radiographic infiltrates and pulmonary eosinophilia, is rarely reported in children. Diagnosis is based on an association of characteristic features including acute respiratory failure with fever, bilateral infiltrates on the chest X-ray, severe hypoxemia and bronchoalveolar lavage fluid &gt;25% eosinophils or a predominant eosinophilic infiltrate in lung biopsies in the absence of any identifiable etiology. We present a 14-month-old girl who was admitted to our pediatric intensive care unit because of acute respiratory distress. She had a fever, dry cough, and progressive dyspnea for 1 day. Chest X-ray showed multifocal consolidations, increased interstitial markings, parenchymal emphysema and pneumothorax. IAEP was confirmed by marked pulmonary infiltrates of eosinophils in the lung biopsy specimen. Most known causes of acute eosinophilic pneumonia, such as exposure to causative drugs, toxins, second-hand smoking and infections were excluded. Her symptoms were resolved quickly after corticosteroid therapy.

  17. [Influence of cortical neurotrophic factors on the neurocytokine production system in acute hemorrhagic stroke].

    Kul'chikov, A E; Kositsyn, N S; Svinov, M M; Vasil'eva, I G; Makarenko, A N

    2009-01-01

    The mechanism of therapeutic action of cortical neurotropic factors (CNTF) was studied in hemorrhagic stroke. In intracerebral hemorrhage, CNTFs were shown to elevate the level of nerve growth factor mRNA and at the same time, produce no effect on its level in intact animals. The neuroactivating action of CNTF in the acute phase of hemorrhagic stroke was achieved by intranasal administration due to the retrograde axon transport of CNTF molecules along the olfactory nerve fibers to the brain, by passing the blood-brain barrier. It was ascertained that the molecules of tritium-labeled CHTF accumulated in the central nervous system following 20 minutes and the level of label accumulation is proportionally increased after 120 minutes. The pattern of accumulation of the intranasally administered label in the olfactory tract and olfactory bulb proves CNTF transportation along these structures of the nervous system. Therefore, when intranasally administered, CNTFs are able to transport to the central nervous system along the olfactory tract and to enhance the expression of nerve growth factor mRNA in hemorrhagic stroke.

    2014-01-01

    Ectopic varices (those outside of the gastro-esophageal region) are occasionally found on endoscopy in patients with portal hypertension; however they account for a small minority of all variceal bleeds. Cases of isolated cecal varices are quite rare and, when described, often present with acute hemorrhage or evidence of occult bleeding. We present the case of a 29-year-old male with a history of idiopathic portal vein thrombosis and known esophageal varices, who presented for evaluation of a...

  19. Super-selective renal artery embolization for the treatment of acute renal hemorrhage

    Objective: To evaluate super-selective renal artery embolization in treating acute renal hemorrhage. Methods: A total of 17 patients with massive renal bleeding were enrolled in this study. After super-selective renal artery catheterization with 4 F and/or 2.7 F catheter was accomplished, renal artery embolization with microcoils, coils and/or PVA particles was carried out. Preoperative CTA was performed in five patients. Plain CT scanning and contrast-enhanced CTA were employed in nine patients at 4 days to 54 months after treatment. Results: Technical success was achieved in all of the 17 cases. Pre-interventional CT scan showed abnormal signs of hemorrhage, arteriovenous malformation, aneurysm, etc. Post-interventional CT scan showed different degrees of renal infarction, renal atrophy, peripheral contraction and depression of the kidney which were located in the areas originally supplied by embolized artery. Compensatory hypertrophy of the contralateral normal kidney occurred in four cases. Abnormal blood vessels disappeared in post-interventional CTA. No coil displacement was seen. Conclusion: For the treatment of acute renal hemorrhage super-selective renal artery embolization is safe and reliable. CTA is of great significance for identifying the bleeding sites before interventional treatment and for evaluating the therapeutic effect. (author)

    2015-01-01

    The levels of soluble intercellular adhesion molecule-1 (sICAM-1) have been reported to increase in patients with idiopathic pulmonary fibrosis. However, the utility of sICAM-1 has not been reported in detail. The aim of this study was to investigate whether sICAM-1 was a useful biomarker for stable idiopathic pulmonary fibrosis (IPF) and early phase of acute exacerbation of IPF. The patients who were diagnosed with IPF between 2013 and 2015 were enrolled. The levels of sICAM-1 and other interstitial pneumonia markers were measured. In this study, 30 patients with stable IPF and 11 patients with acute exacerbation of IPF were collected. Mean sICAM-1 levels were 434 ± 139 ng/mL for the stable phase of IPF, 645 ± 247 ng/mL for early phase of acute exacerbation of IPF, 534 ± 223 ng/mL for connective tissue disease-associated interstitial pneumonia, 221 ± 42 for chronic obstructive pulmonary disease, and 150 ± 32 ng/mL in healthy volunteers. For the stable phase of IPF, sICAM-1 levels correlated with Krebs von den Lungen-6 (KL-6) (r value: 0.41; p value: 0.036). Mean sICAM-1 levels were significantly higher in patients with early phase of acute exacerbation of IPF than with stable phase of IPF (p = 0.0199). Multiple logistic analyses indicated that the predictors for early phase of acute exacerbation of IPF were only sICAM-1 and C-reactive protein (odds ratio: 1.0093; 1.6069). In patients with stable IPF, sICAM-1 levels correlated with KL-6; sICAM-1 might be a predictive indicator for prognosis. In the early phase of acute exacerbation of IPF, sICAM-1 might be more useful for diagnosis than other interstitial pneumonia markers. PMID:26543791

  1. The effect of sennosides on bacterial translocation and survival in a model of acute hemorrhagic pancreatitis.

    Chen, X; Valente, J F; Alexander, J W

    1999-01-01

    Bacterial translocation leading to subsequent infectious complications is a significant determinant of outcome in acute hemorrhagic pancreatitis (AHP). The colonic ileus and impaired intestinal barrier function that often accompany AHP may predispose to translocation. Sennoside is a naturally occurring cathartic and choleretic agent that stimulates intestinal mucous secretion and has potent promotility effects. The impact of sennoside-induced intestinal motility and secretory function on bacterial translocation and survival was studied in a rat model of AHP. Severe acute pancreatitis was induced in rats by the intraductal infusion of 2% sodium deoxycholate (DCA, 0.4 ml/kg). A group of sham-operated rats (group A) received intraductal saline, whereas experimental animals were subsequently administered distilled water (group B) or sennoside solution (group C) by gavage every 8 h. After 48 h, intestinal transit of fluorescein isothiocyanate-labeled dextran, serum endotoxin, and amylase levels, and bacterial translocation to mesenteric lymph nodes (MLNs) and pancreatic tissue were determined. The pancreas and intestine were sampled for histologic study. All group A animals survived and did not develop pancreatitis or endotoxemia, whereas groups B and C all demonstrated severe hemorrhagic pancreatitis with evidence of necrosis. Mortality at 48 h was 55% in group B versus 12.5% in group C. Inhibition of intestinal motility was noted in 40% versus 20%, and endotoxin levels were 61.36+/-28.26 pg/L versus 5.41+/-3.58 pg/L in group B versus group C rats, respectively (ptranslocation of endotoxin and bacteria, restored intestinal motility, increased mucous secretion, and reduced mortality in a model of acute hemorrhagic pancreatitis in the rat. Other cathartics may have similar properties and may be useful in preventing infectious complications in acute pancreatitis. PMID:9888659

    Recurrent or chronic pulmonary hemorrhage is rare in children. Idiopathic pulmonary hemosiderosis (IPH) manifests as hemoptysis, diffuse parenchymal infiltrates on chest radiographs and microcytic hypochromic anemia. The hemoptysis present may be mistaken for more common diseases, delaying the diagnosis and further management. Idiopathic pulmonary hemosiderosis is a disorder of unknown etiology. Treatment of IPH includes immunosuppressive drugs along with supportive measures.

  6. Detection of Early Vessel Leakiness in Acute Ischemic Stroke Using Computed Tomography Perfusion May Indicate Hemorrhagic Transformation

    This short communication presents significantly increased permeability in two patients with acute stroke, indicating an early blood-brain barrier disruption. Neither of the patients had undergone any thrombolytic therapy and hemorrhaged later. Increased permeability was assessed in both patients using a distributed-parameter model of capillary-tissue exchange. Our findings indicate that early physiologic imaging in stroke may identify patients with a high risk of hemorrhagic transformation by revealing pathologic vascular changes and, thus, guide therapeutic options

    Pancreatic panniculitis is an inflammation and necrosis of fat at distant foci in patients with pancreatic disorders, most frequently, pancreatitis and pancreatic carcinoma. Clinically, pancreatic panniculitis is manifested by painless or painful subcutaneous nodules on the legs, buttocks, or trunk. The usual sites are the distal parts of the lower extremities. To the best of our knowledge, there have not been many reports for the radiologic findings of pancreatic panniculitis. In this article, we report a case of pancreatic panniculitis, including radiologic findings of CT and ultrasonography. The patient was presented with painful subcutaneous nodules on the trunk, and had underlying acute pancreatitis and hemorrhagic pseudocysts.

    2012-12-01

    Full Text Available OBJECTIVE: Obstructive sleep apnea is frequent during the acute phase of stroke, and it is associated with poorer outcomes. A well-established relationship between supine sleep and obstructive sleep apnea severity exists in non-stroke patients. This study investigated the frequency of supine sleep and positional obstructive sleep apnea in patients with ischemic or hemorrhagic stroke. METHODS: Patients who suffered their first acute stroke, either ischemic or hemorrhagic, were subjected to a full polysomnography, including the continuous monitoring of sleep positions, during the first night after symptom onset. Obstructive sleep apnea severity was measured using the apnea-hypopnea index, and the NIHSS measured stroke severity. RESULTS: We prospectively studied 66 stroke patients. The mean age was 57.6±11.5 years, and the mean body mass index was 26.5±4.9. Obstructive sleep apnea (apnea-hypopnea index >5 was present in 78.8% of patients, and the mean apnea-hypopnea index was 29.7±26.6. The majority of subjects (66.7% spent the entire sleep time in a supine position, and positional obstructive sleep apnea was clearly present in the other 23.1% of cases. A positive correlation was observed between the NIHSS and sleep time in the supine position (r s = 0.5; p<0.001. CONCLUSIONS: Prolonged supine positioning during sleep was highly frequent after stroke, and it was related to stroke severity. Positional sleep apnea was observed in one quarter of stroke patients, which was likely underestimated during the acute phase of stroke. The adequate positioning of patients during sleep during the acute phase of stroke may decrease obstructive respiratory events, regardless of the stroke subtype.

  11. Endovascular Treatment of Acute Arterial Hemorrhage in Trauma Patients Using Ethylene Vinyl Alcohol Copolymer (Onyx)

    Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4–63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.

    Because the superficial lymphatics in the lungs are distributed in the subpleural, interlobular and peribroncovascular interstitium, lymphatic impairment may occur in the lungs of patients with idiopathic interstitial pneumonias (IIPs) and increase their severity. We investigated the distribution of lymphatics in different remodeling stages of IIPs by immunohistochemistry using the D2-40 antibody. Pulmonary tissue was obtained from 69 patients with acute interstitial pneumonia/diffuse alveola...

  14. Acute hepatitis in three patients with systemic juvenile idiopathic arthritis taking interleukin-1 receptor antagonist

    Hollister J Roger

    2009-12-01

    Full Text Available Abstract Purpose We investigated the etiology of acute hepatitis in three children with systemic Juvenile Idiopathic Arthritis (sJIA taking Interleukin-1 receptor antagonist (IL1RA. Methods Laboratory and clinical data for three children with sJIA diagnosed at ages 13 months to 8 years who developed acute hepatitis during treatment with IL1RA were reviewed for evidence of sJIA flare, infection, macrophage activation syndrome (MAS, malignancy, and drug reaction. Results In all patients, hepatitis persisted despite cessation of known hepatotoxic drugs and in absence of known infectious triggers, until discontinuation of IL1RA. Liver biopsies had mixed inflammatory infiltrates with associated hepatocellular injury suggestive of an exogenous trigger. At the time of hepatitis, laboratory data and liver biopsies were not characteristic of MAS. In two patients, transaminitis resolved within one week of discontinuing IL1RA, the third improved dramatically in one month. Conclusions Although sJIA symptoms improved significantly on IL1RA, it appeared that IL1RA contributed to the development of acute hepatitis. Hepatitis possibly occurred as a result of an altered immune response to a typical childhood infection while on IL1RA. Alternatively, hepatitis could have represented an atypical presentation of MAS in patients with sJIA taking IL1RA. Further investigation is warranted to determine how anti-IL1 therapies alter immune responsiveness to exogenous triggers in patients with immune dysfunction such as sJIA. Our patients suggest that close monitoring for hepatic and other toxicities is indicated when treating with IL1RA.

    This prospective study included 63 eyes with acute branch retinal vein occlusion (BRVO) to evaluate the retinal hemorrhagic patterns at the posterior poles and explore their clinical relevance in macular perfusion differentiation. Retinal hemorrhagic patterns and macular perfusion status were evaluated via fundus photography and fluorescein angiography, respectively. Macular perfusion was judged as nonischemic in 30, ischemic in 28, and undeterminable in 5 among the 63 eyes. Predominant hemorrhagic patterns were flame-shaped in 39 (67.2%) and non-flame-shaped in 19 (32.8%) eyes. All 39 eyes with a flame-shaped hemorrhage showed a nonischemic macula. Of the 19 eyes classified as having a non-flame-shaped hemorrhage, 13 (68.4%) had an ischemic macula and 6 (31.6%) had a nonischemic macula (P non-flame-shaped hemorrhage (P < 0.001), and in those with a nonischemic macula versus those with an ischemic macula (P < 0.001). The area under the curve for parallelism was 0.975 (P < 0.001), suggesting an accurate diagnostic parameter for macular perfusion differentiation. In conclusion, we objectively evaluated retinal hemorrhagic patterns at the posterior pole in BRVO using the parallelism method, which was useful in differentiating macular perfusion status.

  17. Acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery: a case report

    Hagino Tetsuo

    2012-03-01

    Full Text Available Abstract Introduction Spinal anesthesia is a widely used general purpose anesthesia. However, serious complications, such as intracranial subdural hemorrhage, can rarely occur. Case presentation We report the case of a 73-year-old Japanese woman who had acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery. Conclusion This case highlights the need to pay attention to acute intracranial subdural hemorrhage as a complication after spinal anesthesia. If the headache persists even in a supine position or nausea occurs abruptly, computed tomography or magnetic resonance imaging of the brain should be conducted. An intracranial subdural hematoma may have a serious outcome and is an important differential diagnosis for headache after spinal anesthesia.

    Since progressive hemorrhagic injury (PHI) was introduced in neurosurgical literatures, several studies have been performed, the results of which have influenced doctors but do not define guidelines for the best treatment of PHI. PHI may be confirmed by a serial computerized tomography (CT) scan, and it has been shown to be associated with a fivefold increase in the risk of clinical worsening and is a significant cause of morbidity and mortality as well. So, early detection of PHI is practically important in a clinical situation. To analyze the early CT signs of progressive hemorrhagic injury following acute traumatic brain injury (TBI) and explore their clinical significances, PHI was confirmed by comparing the first and repeated CT scans. Data were analyzed and compared including times from injury to the first CT and signs of the early CT scan. Logistic regression analysis was used to show the risk factors related to PHI. A cohort of 630 TBI patients was evaluated, and there were 189 (30%) patients who suffered from PHI. For patients with their first CT scan obtained as early as 2 h post-injury, there were 116 (77.25%) cases who suffered from PHI. The differences between PHIs and non-PHIs were significant in the initial CT scans showing fracture, subarachnoid hemorrhage (SAH), brain contusion, epidural hematoma (EDH), subdural hematoma (SDH), and multiple hematoma as well as the times from injury to the first CT scan (P < 0.01). Logistic regression analysis showed that early CT scans (EDH, SDH, SAH, fracture, and brain contusion) were predictors of PHI (P < 0.01). For patients with the first CT scan obtained as early as 2 h post-injury, a follow-up CT scan should be performed promptly. If the initial CT scan shows SAH, brain contusion, and primary hematoma with brain swelling, an earlier and dynamic CT scan should be performed for detection of PHI as early as possible and the medical intervention would be enforced in time.

    To determine high-resolution computed tomography (HRCT) findings helpful in predicting mortality in patients with acute exacerbation of idiopathic pulmonary fibrosis (AEx-IPF). Sixty patients with diagnosis of AEx-IPF were reviewed retrospectively. Two groups (two observers each) independently evaluated pattern, distribution, and extent of HRCT findings at presentation and calculated an HRCT score at AEx based on normal attenuation areas and extent of abnormalities, such as areas of ground-glass attenuation and/or consolidation with or without traction bronchiectasis or bronchiolectasis and areas of honeycombing. The correlation between the clinical data including the HRCT score and mortality (cause-specific survival) was evaluated using the univariate and multivariate Cox-regression analyses. Serum KL-6 level, PaCO{sub 2}, and the HRCT score were statistically significant predictors on univariate analysis. Multivariate analysis revealed that the HRCT score was an independently significant predictor of outcome (hazard ratio, 1.13; 95% confidence interval, 1.06-1.19, P = 0.0002). The area under receiver operating characteristics curve for the HRCT score was statistically significant in the classification of survivors or nonsurvivors (0.944; P < 0.0001). Survival in patients with HRCT score {>=}245 was worse than those with lower score (log-rank test, P < 0.0001). The HRCT score at AEx is independently related to prognosis in patients with AEx-IPF.

  3. IDIOPATHIC SCLEROSING ENCAPSULATING PERITONITIS CAUSING ACUTE INTESTINAL OBSTRUCTION AND GANGRENE: A CASE REPORT

    Nava

    2016-04-01

    Full Text Available INTRODUCTION Sclerosing encapsulating peritonitis (SEP is a relatively rare cause of intestinal obstruction resulting from encasement of variable lengths of bowel by dense fibro-collagenous membrane. It is more common in young females, and shows tropical and sub-tropical distribution. The idiopathic cases of SEP, which lack any identifiable cause from clinical, radiological and histopathological findings, are also reported under the descriptive term “abdominal cocoon syndrome”. SEP presents with acute or sub-acute intestinal obstruction with or without a mass. In the era of laparoscopic surgery, inadvertent damage to the small bowel at insertion of the trocar and cannula can occur by being unaware of this condition resulting in unnecessary bowel resection. Persistent untreated SEP may advance to bowel gangrene or intestinal perforation, representing life threatening conditions. We report the clinical presentation of a 75-year-old female presenting with signs of intestinal obstruction whose imaging findings revealed abdominal cocoon with bowel gangrene leading to perforation and the same confirmed at surgery. Surgical excision of the fibrotic sac encasing the bowel, resection of gangrenous bowel segment and end ileostomy was performed. Histopathology of the excised membrane confirmed sclerosing encapsulating peritonitis. To our knowledge, only a few cases of abdominal cocoon with perforation have been reported in literature so far. Radiologists should be aware of this relatively rare cause of intestinal obstruction, its imaging findings and complications, as preoperative diagnosis will prevent delay and aid in treatment planning to the surgeon. Identification of soft tissue density membrane encasing congregated small bowel loops into a single area on computed-tomography gives diagnostic clue. Surgical excision of sac, release of bowel loops and adhesions with partial intestinal resection when necessary is the treatment.

    2005-01-01

    In the present paper, the authors review recent advances in clinical and experimental studies on acupuncture treatment of cerebral hemorrhage(CH). Regarding clinical studies, the resuscitation-inducing needling maneuver, and main points of Shuigou(水沟GV 26),Baihui(百会 GV 20) and scalp-points Motor Area(MS 6), Sensory Area(MS 7), etc. are often involved. Concerning experimental studies, the underlying mechanisms of acupuncture of GV-26+"Neiguan"(内关 PC 6), GV-20,GV-26+GV-20, etc. in improving acute CH are introduced. In a word, acupuncture therapy works well in improving clinical symptoms and signs of CH patients, and acupuncture stimulation induced ameilioration of cerebral blood flow, favorable modulation of some bioactive substances as excitatory and inhibitory amino acids, endothelin, CGRP, heat shock protein 70, etc. and neuro-endocrine-immune network may contribute to the effect of acupuncture on CH. In addition, acupuncture combined with medicine and earlier application of acupuncture therapy in the acute stage of CH are recommended in clinical practice.

    2009-02-01

    In Italy, only one study was conducted on the detection of serum thyroid autoantibodies (ATA) in patients with urticaria. This northern-Italy study reported a 23% rate of ATA positiveness in 52 patients with chronic idiopathic urticaria (CIU). During the years 1998-2006, 688 patients with urticaria were hospitalized at our Division of Allergy and Clinical Immunology. Thyroglobulin and thyroperoxidase autoantibodies (TgAb and TPOAb) were assayed at admission in 144/688 patients. Of the 144 patients (mean age: 42.3+/-15.8 yr, range 17-84), 95 (72 women and 23 men) had an history of CIU (CIU group) and 49 (44 women and 5 men) did not [acute urticaria group or (AU)]. Of the 144 patients, 37 (25.7%) tested positive for at least one ATA: 31 with CIU (32.6%) and 6 with AU (12.2%, chi2=7.037, p=0.008). Positiveness for TPOAb or TgAb was 30/37 (81.1%) or 17/37 (45.9%); 10/37 (27.0%). Pre-hospitalization duration of CIU was longer in the 31 ATA positive patients compared to the 64 ATA negative patients (207.2+/-273.4 vs 81.6+/-106.3 weeks, p=0.015). Pre-hospitalization duration of CIU correlated positively with the log10-transformed serum concentration of TPOAb in the 25 CIU patients who tested TPOAb positive (r=0.42, p=0.039). We conclude that our rate of 31/95 (32.6%) positiveness for at least one type of ATA in CIU is greater than that of 6 representative international studies published between the years 2000 and 2006 (111/488 or 22.7%, range 15-29%, chi2=4.884, p=0.027).

    Involvement of the central nervous system in Korean hemorrhagic fever is expected. When such involvement does occur, it is usually in the form of cerebral hemorrhage or pituitary necrosis. Paralytic disease due to Korean hemorrhagic fever is exceptional. A case of transverse myelitis in an adult female, in which a serologic test of immunofluorescent antibodies to Hantaan virus was positive with clinical pictures of Korean hemorrhagic fever, is reported here.

  8. MR image features predicting hemorrhagic transformation in acute cerebral infarction: a multimodal study

    The aims of this study were to observe magnetic resonance imaging (MRI) features and the frequency of hemorrhagic transformation (HT) in patients with acute cerebral infarction and to identify the risk factors of HT. We first performed multimodal MRI (anatomical, diffusion weighted, and susceptibility weighted) scans on 87 patients with acute cerebral infarction within 24 hours after symptom onset and documented the image findings. We then performed follow-up examinations 3 days to 2 weeks after the onset or whenever the conditions of the patients worsened within 3 days. We utilized univariate statistics to identify the correlations between HT and image features and used multivariate logistical regression to correct for confounding factors to determine relevant independent image features of HT. HT was observed in 17 out of total 87 patients (19.5 %). The infarct size (p = 0.021), cerebral microbleeds (CMBs) (p = 0.004), relative apparent diffusion (rADC) (p = 0.023), and venous anomalies (p = 0.000) were significantly related with HT in the univariate statistics. Multivariate analysis demonstrated that CMBs (odd ratio (OR) = 0.082; 95 % confidence interval (CI) = 0.011-0.597; p = 0.014), rADC (OR = 0.000; 95 % CI = 0.000-0.692; p = 0.041), and venous anomalies (OR = 0.066; 95 % CI = 0.011-0.403; p = 0.003) were independent risk factors for HT. The frequency of HT is 19.5 % in this study. CMBs, rADC, and venous anomalies are independent risk factors for HT of acute cerebral infarction. (orig.)

    The aims of this study were to observe magnetic resonance imaging (MRI) features and the frequency of hemorrhagic transformation (HT) in patients with acute cerebral infarction and to identify the risk factors of HT. We first performed multimodal MRI (anatomical, diffusion weighted, and susceptibility weighted) scans on 87 patients with acute cerebral infarction within 24 hours after symptom onset and documented the image findings. We then performed follow-up examinations 3 days to 2 weeks after the onset or whenever the conditions of the patients worsened within 3 days. We utilized univariate statistics to identify the correlations between HT and image features and used multivariate logistical regression to correct for confounding factors to determine relevant independent image features of HT. HT was observed in 17 out of total 87 patients (19.5 %). The infarct size (p = 0.021), cerebral microbleeds (CMBs) (p = 0.004), relative apparent diffusion (rADC) (p = 0.023), and venous anomalies (p = 0.000) were significantly related with HT in the univariate statistics. Multivariate analysis demonstrated that CMBs (odd ratio (OR) = 0.082; 95 % confidence interval (CI) = 0.011-0.597; p = 0.014), rADC (OR = 0.000; 95 % CI = 0.000-0.692; p = 0.041), and venous anomalies (OR = 0.066; 95 % CI = 0.011-0.403; p = 0.003) were independent risk factors for HT. The frequency of HT is 19.5 % in this study. CMBs, rADC, and venous anomalies are independent risk factors for HT of acute cerebral infarction. (orig.)

  10. A complicated case of antepartum eclamptic fit with HELLP syndrome, acute renal failure and multiple intracranial hemorrhages: A mortality report

    Ahmed Samy El-agwany

    2016-04-01

    Full Text Available HELLP is an acronym for hemolysis, elevated liver enzymes and low platelets count, affecting 0.2–12% of all pregnancies or 4–12% of those with preeclampsia. The maternal mortality reported from the literature is up 4% due to disseminated intravascular coagulation, placental abruption, acute renal failure, eclampsia, and cerebral hemorrhage. A 20 year old, G2P1, at 36 weeks of gestation, was referred to our hospital because of postictal coma state with bilateral mydriasis and epistaxis due to repeated antepartum eclamptic fits. Elevated blood pressure level 170/110 mmHg was accompanied with massive proteinuria. Cesarean section was performed and female newborn were delivered. Laboratory findings were characteristic of preeclampsia, HELLP syndrome and renal failure. The patient developed an intraventricular hematoma and an intracerebral hemorrhage with subarachnoid one, which were not suitable to neurosurgical treatment. The patient died from refractory hemolytic anemia, spontaneous bleeding of multiple organs, renal failure and intracranial hemorrhage. Preeclampsia, HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure appropriate management and treatment success.

  11. Immunohistochemical detection of virus through its nuclear cytopathic effect in idiopathic interstitial pneumonia other than acute exacerbation

    G.C. dos Santos

    2013-11-01

    Full Text Available Idiopathic interstitial pneumonias include complex diseases that have a strong interaction between genetic makeup and environmental factors. However, in many cases, no infectious agent can be demonstrated, and these clinical diseases rapidly progress to death. Theoretically, idiopathic interstitial pneumonias could be caused by the Epstein-Barr virus, cytomegalovirus, adenovirus, hepatitis C virus, respiratory syncytial virus, and herpesvirus, which may be present in such small amounts or such configuration that routine histopathological analysis or viral culture techniques cannot detect them. To test the hypothesis that immunohistochemistry provides more accurate results than the mere histological demonstration of viral inclusions, this method was applied to 37 open lung biopsies obtained from patients with idiopathic interstitial pneumonias. As a result, immunohistochemistry detected measles virus and cytomegalovirus in diffuse alveolar damage-related histological patterns of acute exacerbation of idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia in 38 and 10% of the cases, respectively. Alveolar epithelium infection by cytomegalovirus was observed in 25% of organizing pneumonia patterns. These findings were coincident with nuclear cytopathic effects but without demonstration of cytomegalovirus inclusions. These data indicate that diffuse alveolar damage-related cytomegalovirus or measles virus infections enhance lung injury, and a direct involvement of these viruses in diffuse alveolar damage-related histological patterns is likely. Immunohistochemistry was more sensitive than the histological demonstration of cytomegalovirus or measles virus inclusions. We concluded that all patients with diffuse alveolar damage-related histological patterns should be investigated for cytomegalovirus and measles virus using sensitive immunohistochemistry in conjunction with routine procedures.

    Selective abdominal arteriography with an iodinated contrast material is the method of choice for detecting the site of bleeding in patients with acute gastrointestinal hemorrhage in whom the results of endoscopic examination were negative CO2, has been used successfully as a contrast material for arteriography of abdomen and lower limbs. We present the case of a patient in whom suspected gastrointestinal bleeding was detected more rapidly and reliably with co2 than with an iodinated contrast material. (Author) 18 Refs

  14. ACUTE LUNG INJURY COMPLICATING BLOOD TRANSFUSION IN POST-PARTUM HEMORRHAGE: INCIDENCE AND RISK FACTORS.

    2014-10-01

    Full Text Available Background. We retrospectively investigated the incidence and risk factors for transfusion-related acute lung injury (TRALI among patients transfused for post-partum hemorrhage (PPH. Methods. We identified a series of 71 consecutive patients with PPH requiring the urgent transfusion of three or more red blood cell (RBC units, with or without fresh frozen plasma (FFP and platelet (PLT transfusion. Clinical records were then retrieved and examined for respiratory distress events. According to the 2004 consensus definition, cases of new-onset hypoxemia within 6 hours after transfusion, with bilateral pulmonary changes in the absence of cardiogenic pulmonary edema  were identified as TRALI; if an alternative risk factor for acute lung injury was present,  possible TRALI was diagnosed.Results. Thirteen cases of TRALI and 1 case of possible TRALI were identified (overall incidence 19.7%.  At univariate analysis, patients with TRALI received higher number of RBC, PLT and FFP units and had a longer post-partum hospitalization. Among several pregnancy-related diseases (including hypertensive disorders, anemia, intrahepatic cholestasis, gestational diabetes and various pre-existing comorbidities, only gestational hypertension and pre-eclampsia   significantly increased the risk to develop  TRALI (p = 0.006. At multivariate analysis, including both transfusion- and patient-related risk factors, pregnancy-related hypertensive disorders were confirmed to be the only predictors for TRALI, with an odds ratio of 27.7 ( 95% CI 1.27-604.3, p=0.034.Conclusions. Patients suffering from PPH represent a high-risk population for TRALI. In particular, patients with gestational hypertension and pre-eclampsia   have the highest risk, particularly if they are not receiving anti-hypertensive therapy. A careful monitoring of these patients after transfusions is therefore recommended.

  15. Copeptin is associated with mortality and outcome in patients with acute intracerebral hemorrhage

    Merlo Adrian

    2010-05-01

    Full Text Available Abstract Background Spontaneous intracerebral hemorrhage (ICH accounts for a high mortality and morbidity. Early prediction of outcome is crucial for optimized care and treatment decision. Copeptin, the C-terminal part of provasopressin, has emerged as a new prognostic marker in a variety of diseases, but its prognostic value in ICH is unknown. Methods In 40 consecutive patients who were admitted to the hospital within 72 hours after a spontaneous ICH, the plasma copeptin level was measured with a sandwich immunoassay upon admission. The prognostic value of copeptin to predict 30 day mortality and functional outcome after 90 days was assessed. A favorable outcome was defined as a Barthel score above 85 and a score below 3 on the Modified Rankin Scale. Results Copeptin correlated positively with hematoma volume (r = 0.32, p Conclusions Copeptin is a new prognostic marker in patients with an ICH. If this finding can be confirmed in larger studies, copeptin might be an additional valuable tool for risk stratification and decision-making in the acute phase of ICH.

  16. The Acute Inflammatory Response in Trauma / Hemorrhage and Traumatic Brain Injury: Current State and Emerging Prospects

    Y Vodovotz

    2009-01-01

    Full Text Available Traumatic injury/hemorrhagic shock (T/HS elicits an acute inflammatory response that may result in death. Inflammation describes a coordinated series of molecular, cellular, tissue, organ, and systemic responses that drive the pathology of various diseases including T/HS and traumatic brain injury (TBI. Inflammation is a finely tuned, dynamic, highly-regulated process that is not inherentlydetrimental, but rather required for immune surveillance, optimal post-injury tissue repair, and regeneration. The inflammatory response is driven by cytokines and chemokines and is partiallypropagated by damaged tissue-derived products (Damage-associated Molecular Patterns; DAMP’s.DAMPs perpetuate inflammation through the release of pro-inflammatory cytokines, but may also inhibit anti-inflammatory cytokines. Various animal models of T/HS in mice, rats, pigs, dogs, and nonhumanprimates have been utilized in an attempt to move from bench to bedside. Novel approaches, including those from the field of systems biology, may yield therapeutic breakthroughs in T/HS andTBI in the near future.

    Although juxtafacet cysts of the lumbar spine are being reported with increasing frequency, hemorrhage from a ganglion cyst is rare, and the pathophysiologic mechanism of the hemorrhage from the cyst is still unclear. A 75-year-old male presented with sudden radicular leg pain caused by hemorrhage from the ganglion cyst. Computed tomography revealed bony erosion of vertebral body and multiple punched-out lesions on facets. Magnetic resonance imaging showed the neural structure was compressed ...

  18. MRI of acute post-ischemic cerebral hemorrhage in stroke patients: diagnosis with T2*-weighted gradient-echo sequences

    The use of T2*-weighted sequences has been advocated for early differentiation between hematoma and ischemia in patients with acute stroke. Early hemorrhagic transformation of ischemic stroke is an adverse event which may occur under treatment and may impair the prognosis: our aim is to evaluate the ability of T2*-weighted gradient-echo sequence (T2* GRE) to detect post-ischemic cerebral hemorrhage. The imaging procedure included: (1) baseline CT scan at admission. (2) MRI performed within 24 h of therapy onset including: (a) dual fast spin echo T2 sequence, (b) axial isotropic echoplanar diffusion-weighted imaging sequence, (c) conventional T2* GRE, and (d) 3D TOF turbo MRA. Post-ischemic cerebral hemorrhage was diagnosed if T2* GRE detected a focal intraparenchymal area of signal loss. The diameter of this lesion had to be more than 5 mm in order to eliminate past microbleeds. (3) Patients who showed an early suspicion of bleeding on MRI promptly had a second CT scan, and, if this one was negative for bleeding, another CT scan was performed 1 day later. All the other patients had a control CT scan during the first week. Forty-five consecutive patients have been included. T2* GRE showed intracranial bleeding in seven. The diagnosis of post-ischemic cerebral bleeding was confirmed by CT in all patients. Control CT scans did not reveal any post-ischemic cerebral hemorrhage in patients with negative MRI. In one case, hemorrhage was seen earlier on MRI than on CT scan. In conclusion, T2* GRE appeared to be at least as efficient as CT scan in the detection of early post-ischemic cerebral hemorrhage.

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

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

    Full Text Available Pur po se: Our aim was to evaluate the preocular tear film in patients who had acute hemorrhagic conjunctivitis (AHC caused by coxsackievirus A24 variant (CVA24v. Ma te ri als and Met hod: Seventy-six patients having AHC caused by CVA24v were enrolled in this study. An AHC outbreak was seen in Istanbul during August and September 2010 and lasted for four weeks. All the patients were seen at the first days of their disease period and none of them had received any treatment before. Conjunctival swab specimens were taken from the patients at their first visit. Tear film tests including Schirmer test, tear meniscus height measurement and tear break-up time (TBUT were done in all patients. Re sults: The mean age of the patients was 27.8 years (range: 7-68 years. Forty patients were male (53% and 36 patients were female (47%. In bilateral conjunctivitis cases, the mean Schirmer test result was 23.7±4.7 mm, mean TBUT was 15.1±2.4 seconds and the mean tear meniscus height was 0.37±0.06 mm. In unilateral conjunctivitis cases, the mean Schirmer test result was 24.4±3.6 mm, mean TBUT was 15.1±2.3 seconds and the mean tear meniscus height was 0.38±0.07 mm in the diseased eyes. Dis cus si on: The results of the routine preocular tear film tests did not differ in AHC caused by CVA24v when compared with healthy eyes. (Turk J Ophthalmol 2012; 42: 186-9

  1. Localization of bleeding using 4-row detector-CT in patients with clinical signs of acute gastrointestinal hemorrhage

    Purpose: There is no gold-standard regarding the diagnostic work-up and therapy of an acute gastrointestinal (GI) hemorrhage. In most cases endoscopy provides the diagnosis but in a low percentage this modality is not feasible or negative. Purpose of this study was to evaluate the role of multi-phase Multi-Slice-Computertomography (MSCT) as a modality to diagnose and locate the site of acute GI hemorrhage in case of unfeasible or technically difficult endoscopy. Materials and methods: 58 patients, presenting with clinical signs of lower GI hemorrhage, were examined through a 24-month period. Preliminary endoscopy was either negative or unfeasible. Images were obtained with a four-detector row CT with an arterial (4 x 1 mm collimation, 0.8 mm increment, 1.25 mm slice width, 120 kV, 165 mAs) and portal venous series (4 x 2,5 mm collimation, 2 mm increment, 3 mm slice width, 120 kV, 165 mAs). Time interval between endoscopy and CT varied between 30 minutes and 3 hours. The results of the MSCT were correlated with clinical course and surgical or endoscopical treatment. Results: 20 of the 58 patients (34%) undergoing MSCT had a bleeding site identified, thus providing decisive information for the following intervention. In case of a following therapeutic intervention there was 100% correlation regarding the bleeding site. In 38 of the 58 patients (66%), a bleeding site was not identified by MSCT. Twenty of these 38 patients (53%) were stable and required no further treatment. In 18 of these 38 patients further interventional therapy was required due to continuing hemorrhage and in all of those patients the bleeding site was detected by intervention. (orig.)

  2. Acute-onset severe gastrointestinal tract hemorrhage in a postoperative patient taking rivaroxaban after total hip arthroplasty: a case report

    Boland Michael

    2012-05-01

    Full Text Available Abstract Introduction Rivaroxaban, a new oral anticoagulant, is currently licensed for use in patients undergoing orthopedic surgery. It is more efficacious than other anticoagulants such as low molecular weight heparin and does not require daily monitoring. It has also been shown to be efficacious in patients with venous thromboembolism and acute coronary syndrome. Although hemorrhage is a known side effect of this new anticoagulant, we could find no case reports in the literature of patients suffering severe hemorrhage whilst taking rivaroxaban. Thus, we describe the first case of potentially fatal hemorrhage in a patient taking rivaroxaban. Case presentation We report the case of a 58-year-old Caucasian man with acute-onset severe per rectal bleeding who had undergone total hip arthroplasty four weeks prior to the onset of symptoms and was taking rivaroxaban in the postoperative period. Rivaroxaban was discontinued immediately but, having required nine units of packed red blood cells in a peripheral hospital due to a rapidly decreasing hemoglobin level, our patient was transferred to our tertiary referral center where he required a further eight units of packed red blood cells over a 48-hour period to manage his ongoing hemorrhage and maintain hemodynamic stability. No source of bleeding was found on computed tomography angiography and our patient’s condition improved over the following 48 hours with cessation of the hemorrhage. Our patient was discharged home well several days later. A follow-up colonoscopy one week after his discharge was normal. Conclusion Although advantageous with regard to its oral availability and ongoing use without the need for daily monitoring, rivaroxaban does not come without rare but severe side effects. When severe per rectal bleeding occurs in a patient taking rivaroxaban, discontinuation of the offending agent and aggressive hematological replacement are the mainstays of treatment, especially when no

    Fluid resuscitation, hemostasis, and transfusion is essential in care of hemorrhagic shock. Although estimation of the residual blood volume is crucial, the standard measuring methods are impractical or unsafe. Vital signs, central venous or pulmonary artery pressures are inaccurate. We hypothesized that the residual blood volume for acute, non-ongoing hemorrhage was calculable using serial hematocrit measurements and the volume of isotonic solution infused. Blood volume is the sum of volumes...

    2003-07-01

    To determine the diagnostic accuracy of T1-weighted, FLAIR, and GRE MR imagings in the detection of hemorrhagic transformation in patients with acute cerebral infarction and to compare it with CT. Fifty-three patients with acute territorial cerebral infraction were studied prospectively. All patients underwent nonenhanced CT and MRI including the T1-weighted, FLAIR, and GRE. Lesion conspicuity of hemorrhage was scored as follows: 0-none; 1-suspicious; 2-sure. CT and MR imagings were reviewed two radiologists respectively. The mean value of the lesion conspicuity in each CT and MR sequences was compared by means of a Wilcoxon signed ranks test. The time intervals between CT and MR imagings ranged from 3 to 14 hours (mean; 7.6 hours). Hemorrhagic transformation was detected on nonenhanced CT in 26 of 53 patients. In the detection of hemorrhage in patients with acute cerebral infraction, T1-weighted and FLAIR MR imagings were inferior to NECT (p<0.05). By contrast, lesion conspicuity of GRE MR imaging was not different from that of CT (p=0.5). In addition, lesion conspicuity of GRE MR imaging was greater than that of CT in five patients on reader A and two patients on reader B. GRE MR imaging was superior to T1-weighted and FLARI MR imagings, equal to nonenhanced CT in the detection of hemorrhagic transformation in patients with acute cerebral infraction.

  10. Lymphatic fluctuation in the parenchymal remodeling stage of acute interstitial pneumonia, organizing pneumonia, nonspecific interstitial pneumonia and idiopathic pulmonary fibrosis

    E.R. Parra

    2012-05-01

    Full Text Available Because the superficial lymphatics in the lungs are distributed in the subpleural, interlobular and peribroncovascular interstitium, lymphatic impairment may occur in the lungs of patients with idiopathic interstitial pneumonias (IIPs and increase their severity. We investigated the distribution of lymphatics in different remodeling stages of IIPs by immunohistochemistry using the D2-40 antibody. Pulmonary tissue was obtained from 69 patients with acute interstitial pneumonia/diffuse alveolar damage (AIP/DAD, N = 24, cryptogenic organizing pneumonia/organizing pneumonia (COP/OP, N = 6, nonspecific interstitial pneumonia (NSIP/NSIP, N = 20, and idiopathic pulmonary fibrosis/usual interstitial pneumonia (IPF/UIP, N = 19. D2-40+ lymphatic in the lesions was quantitatively determined and associated with remodeling stage score. We observed an increase in the D2-40+ percent from DAD (6.66 ± 1.11 to UIP (23.45 ± 5.24, P = 0.008 with the advanced process of remodeling stage of the lesions. Kaplan-Meier survival curves showed a better survival for patients with higher lymphatic D2-40+ expression than 9.3%. Lymphatic impairment occurs in the lungs of IIPs and its severity increases according to remodeling stage. The results suggest that disruption of the superficial lymphatics may impair alveolar clearance, delay organ repair and cause severe disease progress mainly in patients with AIP/DAD. Therefore, lymphatic distribution may serve as a surrogate marker for the identification of patients at greatest risk for death due to IIPs.

    2010-10-01

    We report a case of dengue hemorrhagic fever (DHF) complicated by acute myocarditis and review the literature. A 65-year-old woman experienced DHF due to dengue virus serotype 3, complicated with acute myocarditis and acute pulmonary edema. Clinically this masqueraded as acute myocardial infarction, with an electrocardiographically depressed ST segment in precordial leads and elevated serum cardiac-specific troponin I level. Under supportive management, the patient recovered 3 days later. A total of 18 pertinent articles involving 339 dengue-affected patients with cardiac complications were found by PubMed search. Clinical manifestations of cardiac complications varied considerably, from self-limiting tachy-brady arrhythmia to severe myocardial damage, leading to hypotension and pulmonary edema. Although rare, a fatal outcome was reported in some cases of dengue with cardiac complications. To avoid otherwise preventable morbidity and mortality, physicians should have a high index of suspicion for cardiac complications in patients with dengue illness and should manage this accordingly.

  13. Prediction of hemorrhagic transformation in acute ischemic stroke using permeability surface of CT perfusion

    Objective: To investigate the value of permeability surface (PS) in predicting hemorrhagic transformation (HT) in acute ischernic stroke (AIS) using CT perfusion (CTP). Methods: The study included 31 consecutive patients who presented symptoms suggestive of an AIS for 3-9 h. All patients underwent CT examination (noncontrast CT, CTP). HT was determined by follow-up CT images. According to presence of HT, the AIS was divided into HT group (PSHT, 11 patients) and non-HT group (PSNo-HT, 20 patients). PS, cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) on both sides of brains were measured.The relative PS (rPS), relative CBF (rCBF), relative CBV (rCBV) and relative MTT(rMTT) were obtained by calculating the ratio of the values of bilateral regions. The rPS between PSHT and PSNo-HT was compared with an exact Wilcoxon signed-rank test. The rCBF, rCBV, rMTT and the PS of the ischemic side between PSHT and PSNo-HT were compared with independent-sample t test. Meanwhile, Spearman rank correlation analysis was conducted to analyze the relationship between the CTP parameters and HT. Results: The PS value of ischemic side was (1.61 ±0.77) ml · min-1 · 100 g-1 for the PSHT group,and the value was (0.91 ± 0.49) ml · min-1 · 100 g-1 for the PSNo-HT group. For the PSHT group, rPS, rCBF, rCBV, rMTT were 2.76 ±0.78, 0.32 ±0.18, 0.66 ±0.31, 2.67 ±0.71, and for the PSNo-HT group, rPS, rCBF, rCBV, rMTT were 1.35 ±0.19, 0.50±0.21, 0.91 ±0.28, 2.62 ± 1.31. Compared with PSNo-HT,PSHT had higher rPS and PS value,and there were significant statistical differences (U=0.000, t=3.070, P<0.01). But rCBF and rCBV values were lower in the PSHT group compared to the PSNo-HT group, and there were significant statistical differences (trCBF=2.343, trCBV=2.210, P<0.05). There was no significant statistical difference in rMTT between the two groups (t=0.118, P>0.05). Significant positive correlations were detected between the rPS and PS with HT (r=0

  14. Low levels of tissue factor lead to alveolar hemorrhage, potentiating murine acute lung injury and oxidative stress

    Background Systemic blockade of Tissue Factor (TF) attenuates acute lung injury (ALI) in animal models of sepsis but the effects of global TF deficiency are unknown. Hypothesis We used mice with complete knockout of mouse TF and low levels (~1%) of human TF (LTF mice) to test the hypothesis that global TF deficiency attenuates lung inflammation in direct lung injury. Methods LTF mice were treated with 10 μg of lipopolysaccharide (LPS) or vehicle administered by direct intratracheal (IT) injection and studied at 24 hours. Results Contrary to our hypothesis, LTF mice had increased lung inflammation and injury as measured by bronchoalveolar lavage cell count (3.4 × 105 WT LPS versus 3.3 × 105 LTF LPS, p=0.947) and protein (493 μg/ml WT LPS versus 1014 μg/ml LTF LPS, p=0.006), proinflammatory cytokines (TNF-α, IL-10, IL-12, p<0.035 WT LPS versus LTF LPS) and histology compared to wild type mice. LTF mice also had increased hemorrhage and free hemoglobin in the airspace accompanied by increased oxidant stress as measured by lipid peroxidation products (F2-Isoprostanes and Isofurans). Conclusions These findings indicate that global TF deficiency does not confer protection in a direct lung injury model. Rather, TF deficiency causes increased intra-alveolar hemorrhage following LPS leading to increased lipid peroxidation. Strategies to globally inhibit tissue factor may be deleterious in patients with ALI. PMID:23033361

    Intracranial hemorrhage (ICH) is a rare but major cause of death in immune thrombocytopenic purpura (ITP). The authors reviewed data of 1,840 patient with ITP, from 5 pediatric hematology centers in Egypt from 1997 to 2007, to study the incidence and risk factors of ICH. Ten cases of ICH were identified with a median age at presentation of 7.5 years; 4 patients had acute ITP, 2 persistent and 4 chronic. The platelet count was late referral to a specialized center. Our results suggest that treatment does not prevent ICH and that it can occur at any time during the course of the disease. Delayed referral can be considered a risk factor for unfavorable outcome of ICH, highlighting the importance of teaching sessions for patients and their parents to minimize subsequent morbidity and mortality of ICH in children with ITP.

    The outcome of intracerebral hemorrhage (ICH) is mainly determined by the volume of the hemorrhage core and the secondary brain damage to penumbral tissues due to brain swelling, microcirculation disturbance and inflammation. The present study aims to investigate the protective effects of cerebrolysin on brain edema and inhibition of the inflammation response surrounding the hematoma core in the acute stage after ICH. The ICH model was induced by administration of type VII bacterial collagenase into the stratum of adult rats, which were then randomly divided into three groups: ICH + saline; ICH + Cerebrolysin (5 ml/kg) and sham. Cerebrolysin or saline was administered intraperitoneally 1 h post surgery. Neurological scores, extent of brain edema content and Evans blue dye extravasation were recorded. The levels of pro-inflammatory factors (IL-1β, TNF-α and IL-6) were assayed by Real-time PCR and Elisa kits. Aquaporin-4 (AQP4) and tight junction proteins (TJPs; claudin-5, occludin and zonula occluden-1) expression were measured at multiple time points. The morphological and intercellular changes were characterized by Electron microscopy. It is found that cerebrolysin (5 ml/kg) improved the neurological behavior and reduced the ipsilateral brain water content and Evans blue dye extravasation. After cerebrolysin treated, the levels of pro-inflammatory factors and AQP4 in the peri-hematomal areas were markedly reduced and were accompanied with higher expression of TJPs. Electron microscopy showed the astrocytic swelling and concentrated chromatin in the ICH group and confirmed the cell junction changes. Thus, early cerebrolysin treatment ameliorates secondary injury after ICH and promotes behavioral performance during the acute phase by reducing brain edema, inflammatory response, and blood-brain barrier permeability.

  17. Differentiating intraparenchymal hemorrhage from contrast extravasation on post-procedural noncontrast CT scan in acute ischemic stroke patients undergoing endovascular treatment

    This study aimed to identify the imaging characteristics that can help differentiate intraparenchymal hemorrhage from benign contrast extravasation on post-procedural noncontrast CT scan in acute ischemic stroke patients after endovascular treatment. We reviewed the clinical and imaging records of all acute ischemic stroke patients who underwent endovascular treatment in two hospitals over a 3.5-year period. The immediate post-procedural CT scan was evaluated for the presence of hyperdense lesion(s). The average attenuation of the lesion(s) was measured. Intraparenchymal hemorrhage was defined as a persistent hyperdensity visualized on follow-up CT scan, 24 h or greater after the procedure. Of the 135 patients studied, 74 (55 %) patients had hyperdense lesion(s) on immediate post-procedural CT scan. Follow-up scans confirmed the diagnosis of intraparenchymal hemorrhage in 20 of these 74 patients. A receiver operating characteristic analysis showed that the average attenuation of the most hyperdense lesion can differentiate intraparenchymal hemorrhage from contrast extravasation with an area under the curve of 0.78 (p = 0.001). An average attenuation of <50 Hounsfield units (HU) in the most visually hyperattenuating hyperdense lesion had 100 % specificity and 56 % sensitivity for identification of contrast extravasations. Petechial hyperdensity was seen in 46/54 (85 %) patients with contrast extravasation versus 9/20 (45 %) patients with intraparenchymal hemorrhage on the immediate post-procedural CT scan (p < 0.001). An average attenuation <50 HU of the most hyperattenuating hyperdense parenchymal lesion on immediate post-procedural CT scan was very specific for differentiating contrast extravasation from intraparenchymal hemorrhage in acute ischemic stroke patients after endovascular treatment.

  19. Acute interventional diagnosis and treatment of upper gastrointestinal arterial hemorrhage: its clinical value and influence factors

    Objective: To evaluate emergent angiography and interventional management in treating massive upper gastrointestinal (GI) arterial hemorrhage, and to discuss the factors influencing the angiographic bleeding signs and the interventional therapeutic results. Methods: The clinical data of 56 patients with massive upper GI arterial hemorrhage, who underwent diagnostic arteriography and interventional management with trans-catheter vasopressin infusion and embolization, were retrospectively analyzed. Systolic blood pressure of both pre-and post-interventional therapy was recorded and statistically analyzed. The arteriographic positive rates were separately calculated according to the catheter tip's location, being placed at the 2nd grade branch or at the 3 rd -4 th grade branch of the artery, and the relation of the positive rate with the tip's location was analyzed. A comparison of the hemostatic effect between trans-catheter vasopressin infusion and trans-catheter embolization was made. Results: The average systolic blood pressure of pre-and post-procedure was (93.14 ± 18.63) mmHg and (11.64 ± 13.61) mmHg respectively, with a significant difference (P = 0.023). The angiographic bleeding signs were demonstrated in 12 cases (21.4%) with the catheter's tip at the 2nd grade branch and in 56 cases (100%) with the catheter's tip at the 3 rd -4 th grade branch,the difference between the two was of statistically significance (P < 0.05). The technical success rate and the clinical hemostasis rate of via catheter vasopressin infusion was 80% (16 / 20) and 55% (11/20) respectively. Of nine re-bleeding cases, seven were successfully controlled with embolization therapy by using microcatheter and two had to receive surgery because of arterial rupture which was proved by angiography. The technical and the clinical rates of success for transcatheter embolization therapy were 93% (42 / 45) and 89% (40 / 45) respectively. Recurrence of bleeding was seen in two patients who got

Patients Forty-two patients (25 male, 17 female; mean age: 53±3.2 years with negative prior radiological investigations underwent EUS. Main outcome measures Prior and later radiological investigations, hospital readmission, and the need for further surgical intervention were also analysed. Results EUS was normal in 17 patients (40.5% and demonstrated signs of recent acute pancreatitis but no other aetiological factor in 8 patients (19.0%. Cholelithiasis or microlithiasis was identified in 9 patients (21.4%, combined gallstones/microlithiasis and choledocholithiasis in was seen in 6 patients (14.3%. In one patient (2.4%, calculi were seen in the common bile duct but not the gallbladder. In a further case with recurrent acute pancreatitis (2.4%, chronic pancreatitis was diagnosed on EUS. All patients with common bile duct stones underwent ERCP and sphincterotomy, and stones were universally confirmed. One patient with gallbladder calculi alone required an ERCP after developing jaundice whilst awaiting cholecystectomy. Conclusions EUS provided additional diagnostic information in 17 of the 42 patients (40.5%. Moreover, exclusion of gallstones/microlithiais is also important as it facilitates a search for other causes of pancreatitis. In conclusion, most cases of cholelithiasis can be diagnosed with standard imaging modalities but when these fail to identify a cause, EUS has an important role to play.

    Full Text Available Cecal perforation is an uncommon phenomenon in a pediatric population. It has been linked to a number of underlying medical conditions, which may result in focal inflammation or relative ischemia including hematologic malignancy, infection, and inflammatory bowel disease. We present an otherwise healthy 16-year-old male diagnosed with acute uncomplicated appendicitis on ultrasound, who was found to have cecal perforation with normal appendix intraoperatively, ultimately requiring ileocectomy. With this report, we aim to present the numerous pathophysiologic etiologies of cecal perforation, and to promote a comprehensive differential diagnosis despite the clinical and radiologic findings consistent with uncomplicated appendicitis.

  5. Should warm fresh whole blood be the first choice in acute massive hemorrhage in emergency conditions?

    Kendigelen, Pınar; Kamalak, Zeynep; Abat, Deniz

    2016-03-01

    Early management of rapid massive hemorrhage requires early administration of blood products and rapid surgical control of bleeding. Professionals in peripheral hospitals with limited resources often work under conditions similar to those in the military. Described in the present report are 3 cases in which warm fresh whole blood (WFWB) was used in patients with massive bleeding who presented to a peripheral hospital that had no blood products suitable for emergency conditions. Described first is the case of a 16-year-old female patient who underwent emergency cesarean section. The patient had massive bleeding from the uterus due to atony. Her hemoglobin (Hb) dropped to 3.5 g/dL. Six units of WFWB were transfused during surgery. Hemodynamic parameters and complete blood count (CBC) stabilized. She was transferred from the intensive care unit (ICU) to obstetrics on day 2 and was discharged on day 7. Described second is the case of a 35-year-old female patient who also underwent emergency cesarean section, and for whom massive bleeding was due to uterine atony. Hb dropped to 2 g/dL and hematocrit (HCT) to 5.4%. Nine units of WFWB were transfused, after which hemodynamic and laboratory parameters stabilized. The patient was extubated the following day, transferred from the ICU to obstetrics on day 3, and was discharged on day 8. Described third is the case of a 36-year-old male patient with stab injuries and hemorrhagic shock who underwent emergency surgery. The patient had injuries to the right renal artery and kidney. Nine units of WFWB were transfused due to continued hemorrhage during surgery. Following surgical control of bleeding and transfusion, hemodynamic parameters improved. The patient was transferred from the ICU on day 5 and discharged on day 10. WFWB transfusion nearly disappeared from civilian medicine after blood was separated into components, and whole blood is not usually available at blood banks. In massive transfusions, WFWB effectively replaces

    We report a term male infant presenting on postnatal day 1 with fulminant hepatic failure. Described congenital infection, metabolic disorders, and cardiovascular etiologies of acute neonatal liver failure were assessed and eliminated. A liver biopsy on postnatal day 10 showed neonatal giant cell hepatitis (NGCH) with an unusual degree of fibrosis for this early postnatal age. NGCH is a clinical diagnosis of cholestatic disorders of unknown etiology in the newborn, and, to our knowledge, has not been previously associated with immediate neonatal hepatic failure. The giant cell transformation is a common response to a variety of insults and only rarely occurs beyond the neonatal period. Most cases present with cholestatic jaundice and varying degrees of coagulopathy, and, many, as in this case, show progressive resolution. PMID:11948391

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

    Full Text Available Objective: To define the prognostic value of clinical and neuroimaging parameters on the 30-th day mortality and clinical outcome after spontaneous intracerebral hemorrhage (sICH. Materials and methods: we examined 88 patients with sICH admitted to Neurology Clinic, UMHAT Pleven within 48 hours after clinical symptoms onset. Glasgow Coma Scale (GCS score was used to assess the primary stroke severity; neurological deficit on admission was assessed by National Institute of Health Stroke Scale (NIHSS; clinical outcome at discharge was evaluated by modified Rankin Scale (mRS and by Glasgow Outcome Scale (GOS on the 30-th day after sICH onset. Hematoma volume was measured by the formula of Kothari: AxBxC/2 in ml. The statistical analysis was performed by SPSS 19.0 and Statgraphics plus 4.1 for Windows. Results: Initial assessment of primary stroke severity and neurological deficit by GCS и NIHSS, hematoma localization and volume were found strongly correlated with the clinical outcome on the 30-th day after the sICH onset. Age and vascular risk factors did not correlate with the clinical outcome. Male patients had better survival on the 30-th day compared with the female ones. Discussion: Neurological deficit on admission, hematoma localization and volume were found reliable predictors of the 30-th day clinical outcome that could serve for early stratification of patients and optimal choice of therapeutic approach.

MATERIALS AND METHODS: To observe the demographic, epidemiological and clinical characteristics, and to explore the predictive effects for prognosis in laboratory findings, we conducted a detailed retrospective analysis of clinical records for critical patients with HFRS complicated by ARDS, treated at the center for infectious diseases, Tangdu Hospital, between January 2008 and December 2012. RESULTS: A total of 48 critical patients with laboratory confirmed HFRS accompanied by ARDS were enrolled in the study, including 27 survivors and 21 non-survivors, with a fatality rate of 43.75%. Thirty-one individuals (64.6% contracted HFRS between the months of September and December. The non-survivors tended to have lower incidence of overlapping phase (P = 0.025. There were no obvious differences in the needs for mechanical ventilation (MV and renal replacement therapy (RRT, except for the need for vasoactive drugs between the survivors and non-survivors (P = 0.001. The non-survivors were found to have higher frequencies of encephalopathy, refractory shock and multiple organ dysfunction syndrome (MODS, lower incidences of acute renal failure (ARF and secondary hypertension (P<0.05. The non-survivors tended to have lower levels of serum creatinine (Scr (P<0.001 and fibrinogen (Fib (P = 0.003, higher incidences of prolonged prothrombin time (PT (P = 0.006 and activated partial thromboplastin time (APTT (P = 0.020 and higher levels of aspartate aminotransferase (AST (P = 0.015, and the laboratory parameters mentioned above reached statistical significance for predicting prognosis (P<0.05.

    Full Text Available Abstract Background Spontaneous intracerebral hemorrhage (ICH is a devastating form of stroke with the high mortality twofold to sixfold higher than that for ischemic stroke. But the treatment of haematomas within the basal ganglia continues to be a matter of debate among neurologists and neurosurgeons. The purpose of this study is to judge the clinical value of minimally invasive stereotactic puncture therapy (MISPT on acute ICH. Methods A prospective controlled study was undertaken. The clinical trial was in compliance with the WMA Declaration of Helsinki - Ethical Principles for Medical Research Involving Human Subjects. According to the enrollment criterion, there were 168 acute ICH cases analyzed, of which 90 cases were performed by MISPT ( MISPT group, MG and 78 cases by Conventional craniotomy (CC group, CG, by means of compare of Glasgow Coma Scale(GCS score, postoperative complications(PC and rebleeding incidence(RI, moreover, long-term outcome of 1 year postoperation judged by Glasgow Outcome Scale (GOS, Barthel Index (BI, modified Rankin Scale (mRS and case fatality(CF. Results MG patients showed obvious amelioration in GCS score compared with that of CG. The total incidence of PC in MG decreased obviously compared with that of CG. The incidences of rebleeding in MG and CG were 10.0% and 15.4% respectively. There was no obvious difference between CFs of MG and CG. For three parameters representing long-term outcome, the GOS, BI and mRS in MG were ameliorated significantly than that of CG. Conclusion These data suggested that the advantage of MISPT was displayed in minute trauma and safety, and seemed to be feasible and to had a trend towards improved long-term outcome.

    Purpose: Prompt and reliable detection of intracranial hemorrhage (ICH) has substantial clinical impact in diagnosis and treatment of stroke and traumatic brain injury. This paper describes the design, development, and preliminary performance characterization of a dedicated cone-beam CT (CBCT) head scanner prototype for imaging of acute ICH. Methods: A task-based image quality model was used to analyze the detectability index as a function of system configuration, and hardware design was guided by the results of this model-based optimization. A robust artifact correction pipeline was developed using GPU-accelerated Monte Carlo (MC) scatter simulation, beam hardening corrections, detector veiling glare, and lag deconvolution. An iterative penalized weighted least-squares (PWLS) reconstruction framework with weights adjusted for artifact-corrected projections was developed. Various bowtie filters were investigated for potential dose and image quality benefits, with a MC-based tool providing estimates of spatial dose distribution. Results: The initial prototype will feature a source-detector distance of 1000 mm and source-axis distance of 550 mm, a 43x43 cm2 flat panel detector, and a 15° rotating anode x-ray source with 15 kW power and 0.6 focal spot size. Artifact correction reduced image nonuniformity by ~250 HU, and PWLS reconstruction with modified weights improved the contrast to noise ratio by 20%. Inclusion of a bowtie filter can potentially reduce dose by 50% and improve CNR by 25%. Conclusions: A dedicated CBCT system capable of imaging millimeter-scale acute ICH was designed. Preliminary findings support feasibility of point-of-care applications in TBI and stroke imaging, with clinical studies beginning on a prototype.

    BACKGROUND. Esophageal varices extending along lesser curvature side of stomach is classified as GOV1. The optimal therapy for GOV1 bleeding is still undetermined. METHODS. One hundred and sixty-two patients diagnosed as acute hemorrhage from GOV1 were enrolled. At endoscopists' discretion, 118 patients received glue injection (Glue group) and 44 patients received ligation to arrest bleeding [endoscopic variceal ligation (EVL) group]. This study aimed to compare hemostasis, rebleeding, complications and mortality within 42 days. RESULTS. Both groups were comparable in baseline data. In 109 patients (92%) in the Glue group and 36 patients (82%) in the EVL group (p = 0.07) 48-h hemostasis was achieved . Hemostasis of active bleeding was achieved in 49 of 55 patients (89%) in the Glue group and 24 of 28 patients (85%) in the EVL group (p = 0.70). Treatment failure was noted in 14% of the Glue group and 23% in the EVL group (p = 0.22). Eight patients in the Glue group and four patients in the EVL group rebled between 5 and 42 days (p = 0.73). A total of 48 and 19 adverse events occurred in the Glue and EVL groups, respectively (p = 0.85). Six patients in the Glue group and seven patients in the EVL group encountered posttreatment gastric ulcer bleeding (p = 0.04). Seventeen patients (14%) in the Glue group and 10 (23%) patients in the EVL group died within 42 days (p < 0.001). CONCLUSIONS. Banding ligation was similar to glue injection in achieving successful hemostasis of acute bleeding from GOV1. However, a higher incidence of posttreatment ulcer bleeding and mortality may be associated with banding ligation. PMID:24047398

    The use of T2{sup *}-weighted sequences has been advocated for early differentiation between hematoma and ischemia in patients with acute stroke. Early hemorrhagic transformation of ischemic stroke is an adverse event which may occur under treatment and may impair the prognosis: our aim is to evaluate the ability of T2*-weighted gradient-echo sequence (T2{sup *} GRE) to detect post-ischemic cerebral hemorrhage. The imaging procedure included: (1) baseline CT scan at admission. (2) MRI performed within 24 h of therapy onset including: (a) dual fast spin echo T2 sequence, (b) axial isotropic echoplanar diffusion-weighted imaging sequence, (c) conventional T2* GRE, and (d) 3D TOF turbo MRA. Post-ischemic cerebral hemorrhage was diagnosed if T2{sup *} GRE detected a focal intraparenchymal area of signal loss. The diameter of this lesion had to be more than 5 mm in order to eliminate past microbleeds. (3) Patients who showed an early suspicion of bleeding on MRI promptly had a second CT scan, and, if this one was negative for bleeding, another CT scan was performed 1 day later. All the other patients had a control CT scan during the first week. Forty-five consecutive patients have been included. T2* GRE showed intracranial bleeding in seven. The diagnosis of post-ischemic cerebral bleeding was confirmed by CT in all patients. Control CT scans did not reveal any post-ischemic cerebral hemorrhage in patients with negative MRI. In one case, hemorrhage was seen earlier on MRI than on CT scan. In conclusion, T2{sup *} GRE appeared to be at least as efficient as CT scan in the detection of early post-ischemic cerebral hemorrhage. (orig.)

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

  20. Risk of acute exacerbation of interstitial pneumonia after pulmonary resection for lung cancer in patients with idiopathic pulmonary fibrosis based on preoperative high-resolution computed tomography

    In patients with lung cancer accompanied by idiopathic pulmonary fibrosis (IPF), acute exacerbation of the IPF often occurs after pulmonary resection; however, few studies have been done to identify its preexisting risk factors. We analyzed the high-resolution computed tomography (HRCT) findings of IPF to identify the radiological characteristics of IPF susceptible to acute exacerbation after lung cancer surgery. We reviewed retrospectively 28 lung cancer patients with IPF who underwent pulmonary resection. Clinical data, respiratory function, HRCT findings, and historical features were compared between the acute exacerbation (n=9) and nonexacerbation (n=19) groups. The classification of radiological findings of IPF on HRCT was done using a scoring system of seven factors related to the interstitial shadow, including fibrosis, ground-glass opacity, and low-attenuation area. There were no significant differences in clinical background, respiratory function, composite physiologic index, or pathological features between the groups; however, the degree of fibrosis on preoperative HRCT was significantly higher in the exacerbation group (P<0.003). The fibrosis score was higher on the opposite side to the lung cancer in the exacerbation group (P<0.05). Although it is difficult to predict postoperative acute IPF exacerbation, the degree and laterality of co-existing fibrosis seem to be predictors. (author)

  1. Localization of the acute lower gastrointestinal hemorrhage in vivo-in vitro labeling of red blood cells with sup(99m)Tc

    For the detection and localization of acute lower gastrointestinal hemorrhage in vivo-in vitro labeling of red blood cells with sup(99m)Tc and sup(99m)Tc sulfur colloid has been sugested. The procedure for labeling RBC with sup(99m)Tc consisted in injecting IV 1 mg of ClSn; 20 minutes after injection of tin 10 cc of blood were withdrawn in a syringe containing 20 mCi of sup(99m)Tc; this was incubated for 10 minutes and then injected IV. Scintigraphy of the abdominal cavity was done in supine position and performed with a large field gamma camera with a parallel hole-low energy colimator. Computer adquisition of images was started 5 minutes after RBC injection and made at the rate of one enery 5 minutes for 45 minutes. 14 patients were studied divided in: a) control: 6 patients. b) with active gastrointestinal hemorrhage: 4 patients had positive scintigraphy. The hemorrhage was documented with superior mesenteric arteriography, endoscopy and/or necropsy. The sensitivity was 100%. In 4 out of 14 patients scintigraphy with sup(99m)Tc RBC compared with simultaneous sup(99m)Tc sulfur colloid demonstrated that all patients with positive sup(99m)Tc RBC had also positive sup(99m)Tc sulfur colloid scintigraphy. c) without active gastrointestinal hemorrhage: all of them had negative scintigraphy (specificity 100%). Abdominal scintigraphy with sup(99m)Tc RBC or sulfur colloid are both sensitive for detection and localization of lower gastrointestinal bleeding and the negative study suggests the absence of active hemorrhage. It is suggested that the sup(99m)Tc sulfur colloid scintigraphy should be the initial procedure to study these patients and abdominal arteriography should be performed only in patients with positive abdominal scintigraphy.

    from Paco2. The TcPco2 or GiPco2 values did not differ significantly at any time point in birds that survived or died in any of the groups and across all groups. These results showed no difference in mortality in leghorn chickens treated with fluid resuscitation after hemorrhagic shock and that the PCV and hemoglobin concentrations increased by 3 days after acute hemorrhage with or without treatment. The different CO2 measurements document changes in CO2-values consistent with poor perfusion and may prove useful for serial evaluation of responses to shock and shock treatment. PMID:23971219

  3. Idiopathic anaphylaxis.

    Greenberger, Paul A

    2007-05-01

    Idiopathic anaphylaxis is a prednisone-responsive condition without external cause, but it can coexist with food-, medication-, or exercise-induced anaphylaxis. Mast cell activation may occur at night or after foods that have been eaten with impunity many times previously. Idiopathic anaphylaxis can be classified into frequent (if there are six or more episodes per year or two episodes in the last 2 months) or infrequent (if episodes occur less often). Idiopathic anaphylaxis-generalized consists of urticaria or angioedema associated with severe respiratory distress, syncope or hypotension, and gastrointestinal symptoms. Idiopathic anaphylaxis-angioedema consists of massive tongue enlargement or severe pharyngeal or laryngeal swelling with urticaria or peripheral angioedema. The differential diagnosis of idiopathic anaphylaxis is reviewed, and treatment approaches are presented. PMID:17493503

    This study sought to determine whether the permeability related parameter K(trans), derived from computed tomography perfusion (CTP) imaging, can predict hemorrhagic transformation (HT) in patients with acute ischemic stroke who receive intra-arterial thrombolysis. Data from patients meeting the criterion were examined. CTP was performed and K(trans) maps were used to assess the permeability values in HT and non-HT regions. A receiver operating characteristic (ROC) curve was calculated, showing the sensitivity and specificity of K(trans) for predicting HT risk. Composite images were produced to illustrate the spatial correlations among perfusion, permeability changes and HT. This study examined 41 patients. Twenty-six patients had hemorrhagic infarction and 15 had parenchymal hemorrhage. The mean K(trans) value in HT regions was significantly lower than that in the non-HT regions (0.26 ± 0.21/min vs. 0.78 ± 0.64/min; P < 0.001). The ROC curve analysis identified an optimal cutoff value of 0.334/min for K(trans) to predict HT risk. Composite images suggested ischemic regions with low permeability, or the mismatch area of low perfusion and high permeability, more likely have HT. HT regions after intra-arterial thrombolysis had lower permeability values on K(trans) maps. The mismatch area of lower perfusion and higher permeability are more likely to develop HT. PMID:27302077

  5. Examination of acute treatment strategies in 314 patients with putaminal hemorrhage from the view point of functional prognosis in kaifukuki rehabilitation wards

    We examined the influence of acute treatment strategies for putaminal hemorrhage from the view point of the functional prognosis in Kaifukuki rehabilitation wards. Subjects were 314 patients with putaminal hemorrhage for inpatient rehabilitation in our hospital. For all patients, Functional Independence Measure (FIM), Barthel Index (BI), Independence of Gait (IOG) was measured on admission and discharge, respectively. We examined the functional prognosis, according to method of treatment, age, volume of hematoma, CT classification, side of damage, sex, and hospitalization waiting period. A significant difference was admitted with FIM, BI, and IOG in the age, the volume of hematoma, the hospitalization waiting period, and the CT classification (p<0.05). The functional prognosis was excellent in the conservative treatment than in the surgical treatment. The hospitalization waiting period was significantly a long term in the surgical treatment (p<0.05). In the analysis where the age is arranged the volume of hematoma, the surgical treatment was more excellent than the conservative treatment, in the patients less than 70 years old and the volume of hematoma with 60 ml or more. The functional prognosis of putaminal hemorrhage was excellent in the conservative treatment, but the stereotactic hematoma evacuation is recommended to the limited case as a surgical treatment. Early rehabilitation is a pressing need for the improvement of the functional prognosis. Especially, it is indispensable to shorten the hospitalization waiting period in the surgical treatment.

    Diffuse alveolar hemorrhage (DAH) is characterized by the presence of hemoptysis, anemia, and the presence of diffuse parenchymal infiltrates on imaging studies. Idiopathic pulmonary hemosiderosis (IPH) is an uncommon cause of diffuse alveolar hemorrhage (DAH) and is classically known to present in childhood. Adult-onset IPH is extremely rare. We report the case of a 48-year-old female patient who presented with hemoptysis and acute hypoxic respiratory failure, requiring intubation and mechanical ventilation. Imaging studies showed diffuse bilateral patchy infiltrates. Bronchoalveolar lavage (BAL) confirmed the diagnosis of DAH. Extensive workup including video-assisted thoracoscopic surgical lung biopsy (VATS) failed to reveal any vasculitis, infectious, immunological or connective tissue disorder, as the underlying cause for DAH. The patient was successfully treated with high-dose steroid therapy. PMID:26180395

  12. Acute Paraplegia due to Thoracic Hematomyelia

    Celik, Bahattin; Canbek, Ihsan; Karavelioğlu, Ergun

    2016-01-01

    Spontaneous intraspinal intramedullary hemorrhage is a rare entity with the acute onset of neurologic symptoms. The etiology of idiopathic spontaneous hematomyelia (ISH) is unknown, and there are few published case reports. Hematomyelia is mostly associated with trauma, but the other nontraumatic etiologies are vascular malformations, tumors, bleeding disorders, syphilis, syrinx, and myelitis. MRI is a good choice for early diagnosis. Hematomyelia usually causes acute spinal cord syndrome due to the compression and destruction of the spinal cord. A high-dose steroid treatment and surgical decompression and evacuation of hematoma are the urgent solution methods. We present idiopathic spontaneous hematomyelia of a previously healthy 80-year-old male with a sudden onset of back pain and paraplegia.

  13. Experimental acute intracerebral hemorrhage: Value of MR sequences for a safe diagnosis at 1.5 and 0.5 T

    To determine the detectability of intracerebral hematomas with MR imaging at 1.5 T and 0.5 T with fluid attenuated inversion recovery turbo spin-echo (FLAIR) and gradient-echo sequences. Material and Methods: Twenty-seven intracerebral hematomas were created in 25 piglets by injection of venous blood into the brain through a burr hole. All were imaged with T2*-weighted gradient echo sequences (fast field echo, FFE), T2-weighted fluid attenuated inversion recovery turbo spin-echo sequences (FLAIR), T2-weighted turbo spin-echo (TSE) and T1-weighted spin-echo sequences. Follow-up was performed on the 2nd, 4th and 10th postoperative days. Ten animals were additionally investigated with similar sequences at 0.5 T. Histologic correlation was obtained in all cases. Results: T2* FFE sequences detected all acute intracerebral hematomas and demonstrated the size correctly at 1.5 T and 0.5 T. The conspicuity was better at 1.5 T. FLAIR sequences were unreliable in the hyperacute phase at 1.5 T. However, subarachnoid and intraventricular extension was best appreciated with FLAIR images. T2 TSE images were incapable of detecting para ventricular and subarachnoid hemorrhages, but clearly demonstrated intracerebral blood in other locations. T1-weighted images were insensitive to hemorrhage in the acute state but very useful in subacute and chronic hematomas. Conclusion: The safe and reliable diagnosis of intracerebral hemorrhage is probably possible with MR imaging at 1.5 T and 0.5 T even of hematomas less than 90 min old, but requires the application of at least FLAIR, T2* FFE and T1 sequences and is therefore time consuming

    2006-03-01

    Full Text Available Introduction: lower gastrointestinal hemorrhage (LGIH is generally self-limiting, and the most frequent etiologies are located at colonic level. The objective here is to analyze the diagnostic and therapeutic handling of acute LGIH when its etiology was located in the small intestine. Patients and methods: between 1975 and March 2002, 12 acute cases of LGIH originating in the small intestine were admitted to our service. All consulted the hospital with acute rectorrhage, requiring a transfusion of at least 3 units of concentrated red blood cells. The mean age was 54 ± 21 years, 58% were women, and 83% had experienced previous episodes of LGIH. Results: in eleven cases (92% an urgent lower and upper endoscopy was performed without locating the source of bleeding. An arteriography was indicated in 7 patients (58%, which located the bleeding origin in 5 of them. In two cases a scintigraphy was performed, showing a Meckel's diverticulum in one patient and a normal image in another. All were operated on; in 8 cases (67%, surgery was urgent; in 9 cases, a tumor was found, and in three additional patients, a case of Meckel's diverticulum was found, with a resection being carried out for all lesions. Histology showed a leiomyoma in 7 cases, a Meckel's diverticulum in 3 cases, a leiomyoblastoma in 1, and an angioma in the remaining case. After a mean follow-up of 132 ± 75 months, the leiomyoblastoma resulted in death, and there was a relapse in the case of angioma, which was successfully embolized with interventional radiology. Conclusions: acute LGIH originating in the small intestine should be considered a possible etiology when digestive endoscopy does not locate the source of bleeding, with arteriography being a useful diagnostic technique for bleeding localization. Surgery is the definitive treatment - it confirms the etiology and rules out the presence of malignancy.Introducción: la hemorragia digestiva baja (HDB es generalmente autolimitada y

  19. CT findings in hemorrhagic infarction

    7 cases of hemorrhagic infarction in which a high-density area in a low-density area were revealed on follow-up CT scan are reported. Symptomatically, 4 cases were completed strokes, while 3 cases were RIND. Recanalization of the occluded vessel was seen in all 5 cases on which follow-up angiography was performed. Hemorrhagic infarction was recognized between the 6th and 21st day after onset. CT scan revealed various patterns of hemorrhagic infarction - massive hematoma, watershed hemorrhage, diffuse petechial hemorrhage, etc. Clinical prognoses of these cases were provided in two groups. 3 cases whose clinical symptoms deteriorated at the time of hemorrhage died. On the other hand, 4 cases whose clinical symptoms were stationary, but who nevertheless had hemorrhagic infarction, had good or excellent prognoses. Hemorrhagic infarction of the former group took place during the acute stage of cerebral ischemia(6-8th day after onset), but that of the latter group took place during the subacute stage of cerebral ischemia (12-21st day after onset). Contrast enhancement was seen in all the cases except for one case of the acute stage. Contrast enhancement in the acute stage was recognized in 2 cases on the 4th day after onset. (author)

    Gastrointestinal stromal tumors (GISTs) represent the majority of primary nonepithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Jejunal GISTs account for approximately 10 % of GISTs. Patients usually present with abdominal discomfort. Jejunal GISTs may cause symptoms secondary to obstruction or hemorrhage. Pressure necrosis and ulceration of the overlying mucosa may cause gastrointestinal blee...

    To explore the therapeutic effects of the method of promoting blood circulation and removing blood stasis on hemorrhagic apoplexy of acute stage, 45 cases were treated by the method and observed for their conscious state and motor function, which were compared with 40 cases treated with regular western drugs. The results showed that the effective rate in the treated group was 82.2% and that in control group 60% with a significant difference (P<0.05) between the two groups. In the treated group, the scores of the conscious state and the motor function after treatment were elevated dramatically (P<0.01), indicating a much better effect in the treated group than in the control group.

    Full Text Available Background: Hemorrhagic transformation (HT following acute ischemic stroke is a major problem, especially for the indication of reperfusion therapy including intravenous administration of recombinant tissue plasminogen activator (IV rt-PA. The specific predictive factors of HT have not yet been established. The present study evaluated the findings of computed tomography perfusion (CTP images as predictors of subsequent HT to identify patients with low HT risk for reperfusion therapy such as IV rt-PA. Methods: We retrospectively reviewed 68 consecutive stroke patients (41 males; mean age 72.9 years with steno-occlusive lesions in the major trunk, including 10 patients who underwent IV rt-PA. Each HT was detected on a follow-up T2*-weighted magnetic resonance image until 2 weeks after stroke onset and categorized into four groups [hemorrhagic infarction (HI type 1 and 2, and parenchymal hematoma (PH type 1 and 2] according to the European Cooperative Acute Stroke Study (ECASS classification. We assessed clinical features and radiological findings between the HT and non-HT groups or the PH2 and non-PH2 groups. The efficacy of initial time to peak (TTP mapping of CTP for predicting HT or PH2 was evaluated. Results: Thirty-four patients (50% developed subsequent HT: 18 (52.9% had HI and 16 (47.1% had PH, including 9 PH2 patients (13.2%. IV rt-PA was not significantly associated with HT or PH2 occurrence. Forty of the 68 patients (59% revealed defect areas on the initial TTP mapping (TTP map-defect, and 34 of these 40 patients (85% developed secondary HT and 9 patients (22.5% developed PH2. Initial ‘TTP map-defect’ was significantly associated with the occurrence of HT (p Conclusions: Initial ‘TTP map-defect’ of CTP could accurately predict HT risk including PH2 risk and identify low-risk patients even in the delayed period.

  4. Comparison of Hemostatic Durability between N-Butyl Cyanoacrylate and Gelatin Sponge Particles in Transcatheter Arterial Embolization for Acute Arterial Hemorrhage in a Coagulopathic Condition in a Swine Model

    This study was designed to compare the efficacy of transcatheter arterial embolization (TAE) with N-butyl cyanoacrylate (NBCA) or gelatin sponge particles (GSP) for acute arterial bleeding in a coagulopathic condition using a swine model. Four healthy swine were divided into two coagulopathic conditions: mild and severe. Five hemorrhages were created in each swine (10 hemorrhages per coagulopathy). Mild coagulopathy was achieved by bloodletting 10% of the total circulatory whole blood and preserving activated clotting time (ACT) less than 200 s (ACT 400 s (ACT > 400-second state). For each state, of ACT 400 s, TAE was conducted with GSP or NBCA to control five hemorrhages arising from artificially created renal and splenic injuries. Angiography immediately after TAE with GSP or NBCA showed complete occlusion in both coagulopathic conditions. In the ACT 400-second state, follow-up angiography showed recurrent hemorrhage in four (80%) of the five hemorrhages embolized with GSP and in one (20%) of the five hemorrhages embolized with NBCA. Microscopically, red thrombi were observed densely surrounding GSP in mild coagulopathy but were scarce in severe coagulopathy. In a condition with severe coagulopathy, TAE with NBCA was more effective in durability to cease active arterial bleeding than with GSP.

    Acute intracerebral hemorrhage (ICH) associated with mild anemia is commonly observed on radiological examination, and there are several reports of ruptured aneurysms occurring with ICH but without accompanying subarachnoid hemorrhage. However, the relationship among computed tomography (CT), magnetic resonance imaging (MRI), and intraoperative findings of ICH caused by ruptured cerebral aneurysm in patients with severe chronic anemia has been rarely reported and is poorly understood. Here, we report atypical radiological and intraoperative findings of acute ICH caused by ruptured cerebral aneurysm in a patient with severe chronic anemia. A 64-year-old man with anemia was admitted to our hospital after he experienced left hemiparesis and a disturbance of consciousness. At a referring institution, he showed evidence of macrocytic anemia (white blood cell count, 9,000/μL; red blood cell count, 104×10(4)/μL; hemoglobin, 4.0 g/dL; hematocrit, 12.2%; and platelet count, 26.6×10(4)/μL). Both CT and MRI showed a right frontal ICH. The outer ring of the hematoma appeared as low-density area on CT, a low-intensity area on T1-weighted MRI, and a high-intensity area on T2-weighted MRI with a serous component. The patient received a blood transfusion and underwent surgical removal of the hematoma the following day. The white serous effusion visualized with CT and MRI was identified as a blood clot in the hematoma cavity. The blood that leaks from blood vessels appears as a high-intensity area on CT because it undergoes plasma absorption in a solidification shrinkage process, and is, therefore, concentrated. Although we did not examine the white effusion to determine if serous components were present, we speculated that the effusion may have contained serous components. Therefore, we removed the part of the effusion that appeared as a low-density area on CT. The presence of ICH without subarachnoid hemorrhage suggested the possible adhesion and rupture of a previous

    Gastrointestinal stromal tumors (GISTs) represent the majority of primary nonepithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Jejunal GISTs account for approximately 10 % of GISTs. Patients usually present with abdominal discomfort. Jejunal GISTs may cause symptoms secondary to obstruction or hemorrhage. Pressure necrosis and ulceration of the overlying mucosa may cause gastrointestinal bleeding, and patients who experience significant blood loss may suffer from malaise and fatigue. Literature has classified small-bowel GISTs on the basis of size, and various established guidelines have advised conservative management of small jejunal GISTs (lower gastrointestinal hemorrhage in a 50-year-old postmenopausal woman necessitating an emergency laparotomy to control the bleed. The management of very small (<2 cm) small-bowel GISTs is controversial. While guidelines are primarily based on the risk of malignancy in GISTs, no guideline predicting the risk of complications in small-bowel GISTs exists. Hence, these tumors should be removed even if incidentally detected. PMID:25972676

    2012-01-01

    Full Text Available Introduction. Idiopathic scoliosis is a structural and lateral curvature of the spine for which a currently recognizable cause has not been found and there is no basic evidence for physical and radiographic pathology. Complications. Scoliosis could be a cause of the back pain, deformities, respiratory and cardiology problems. There is a higher risk for decreasing of bone mineral density. Diagnosis and Management. Physical examination, radiography and stereophotogrametry are used in diagnostics of idiopathic scoliosis. The management of idiopathic scoliosis can be conservative or operative. The main forms of conservative management are: therapy exercises, electrical stimulation and spinal orthosis. The primary aim of scoliosis management is to stop curvature progression. The improvement of pulmonary function (vital capacity and treatment of pain are also of major importance. The guidelines for Conservative Management of Scoliosis. The International Society on Scoliosis Orthopaedic and Rehabilitation Treatment gave the guidelines for conservative management of scoliosis. Conservative management of scoliosis includes: a Lyonaise, Side-Shift, Dobosiewicz, Schroth and other kinesitherapy methods, b scoliosis intensive rehabilitation which appears to be effective with respect to many signs and symptoms of scoliosis and with respect to impeding curvature progression and c brace treatment, which has been found to be effective in preventing curvature progression and thus in altering the natural history of idiopathic scoliosis. Conclusion. The International Society has given the standards for kinesitherapy, intensive rehabilitation and spinal orthosis in clinical practice and clinical investigations. Surgical procedures can improve curves in the frontal plane, but have important limitations in maintaining fixation and achieving correction in other planes.

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

  12. Efficacy and safety of Panax notoginseng saponin therapy for acute intracerebral hemorrhage: meta-analysis and mini review of potential mechanisms of action

    Full Text Available Intracranial/intracerebral hemorrhage (ICH is a leading cause of death and disability in people with traumatic brain injury (TBI and stroke. No proven drug is available for ICH. Panax notoginseng (total saponin extraction, PNS is one of the most valuable herb medicines for stroke and cerebralvascular disorders in China. We searched for randomized controlled clinical trials (RCTs involving PNS injection to treat cerebral hemorrhage for meta-analysis from various databases including the Chinese Stroke Trials Register, the trials register of the Cochrane Complementary Medicine Field, the Cochrane Central Register of Controlled Trials, MEDLINE, Chinese BioMedical disc, and China Doctorate/Master Dissertations Databases. The quality of the eligible trials was assessed by Jadad’s scale. Twenty (20 of the 24 identified randomized controlled trials matched the inclusive criteria including 984 ICH patients with PNS injection and 907 ICH patients with current treatment (CT. Compared to the CT groups, PNS-treated patients showed better outcomes in the effectiveness rate (ER, neurological deficit score (NDS, intracranial hematoma volume (IHV, intracerebral edema volume (IEV, Barthel Index (BI, the number of patients died (NDP and incidence of adverse events. Conclusion: PNS injection is superior to CT for acute ICH. A review of the literature shows that PNS may exert multiple protective mechanisms against ICH-induced brain damage including hemostasis, anti-coagulation, anti-thromboembolism, cerebral vasodilation, invigorated blood dynamics, anti-inflammation, antioxidation and anti-hyperglycemic effects. As PNS has a long clinical track record in Asia, it could potentially become a therapy option to treat ICH in the US and Europe. Further clinical trials with better experimental design could determine the long-term effects of PNS treatment for TBI and stroke.

    2016-01-01

    Background and Objectives A number of etiologies of idiopathic sudden sensorineural hearing loss (ISSNHL) have been proposed, including viral infection, vascular disturbance, and immune-mediated mechanisms. Intralabyrinthine hemorrhage (ILH) as a cause of SSNHL is extremely rare, and there have been no studies defining the characteristics of hearing impairment and prognosis in patients with ISSNHL due to ILH. This study aimed to investigate the difference in impaired hearing patterns and prognosis for hearing recovery between patients with ISSNHL due to ILH confirmed by magnetic resonance imaging (MRI) and sex- and age-matched patients with ISSNHL due to causes other than ILH. Subjects and Methods We compared the results of audiometry and MRI in 12 patients who had ILH on MRI (hemorrhage group) and in 23 sex- and age-matched controls without abnormal findings related to their hearing loss on MRI (non-hemorrhage group). Initial hearing impairment, progression, and recovery of hearing loss were compared between the two groups. Results A majority of patients (92%) in the hemorrhage group complained of dizziness. Initial hearing impairment was more frequent in the hemorrhage group than in the non-hemorrhage group (94.09±35.9 vs. 66.66±30.1, p-value=0.036). The final recovery threshold in the hemorrhage group was worse (78.19±46.26 vs. 37.17±31.96, p-value=0.014) than that in the non-hemorrhage group. In the hemorrhage group, hearing recovery seemed to occur less often at high frequencies (2,000, 4,000, and 8,000 Hz) than at low frequencies (250, 500, and 1,000 Hz). Conclusions The presence of ILH was associated with poor hearing prognosis and the occurrence of vertigo. The abrupt onset of hearing loss associated with vertigo and the presence of hyperresonance on fat-suppressed T1-weighted MRI images of labyrinthic fluid strongly suggests acute intralabyrinthine hemorrhage, and is predictive of considerable hearing impairment and poor prognosis.

    Idiopathic pulmonary hemosiderosis is a very rare condition rarely affecting adults and causing recurrent episodes of diffuse alveolar haemorrhage that may lead to lung fibrosis. Due to lack of pathognomonic findings, IPH diagnosis is established upon exclusion of all other possible causes of DAH in combination with specific pathologic findings revealing bland alveolar haemorrhage with absence of vasculitis and/or accumulation of immune complexes within lung parenchyma. Here we describe a rare case of idiopathic pulmonary hemosiderosis in an otherwise healthy 27-year-old Greek male patient with relapsing episodes of fever accompanied by general fatigue and discomfort. He was at this time point a light smoker and had been hospitalised once in the past for similar symptoms. His iron deficiency anemia coupled with chest high-resolution computed tomography and bronchoalveolar lavage revealed findings compatible with diffuse alveolar hemorrhage. After excluding all other sources of bleeding through extensive gastrointestinal workup and thorough immunologic profile, video-assisted thoracic lung biopsy was performed and the diagnosis of Idiopathic Pulmonary Hemosiderosis was established. Patient was treated with high doses of oral corticosteroids, leading to clinical response. We highlight the need for vigilance by the respiratory physician for the presence of DAH, a challenging, acute condition requiring early recognition along with identification of the underlying syndrome and appropriate treatment to achieve optimal results.

  2. Hemorrhage and vascular abnormalities

    While many brain lesions have a similar appearance on MRI and CT, this is not true of hemorrhage. On CT, acute hemorrhage becomes hyperdense within an hour as the clot forms. This lasts for several days and then fades to isodensity and eventually hypodensity. On MRI, hemorrhage less than 12 to 24 hours old may not be distinguishable from vasogenic edema. Its appearance subsequently is an evolving pattern of variable signal intensity which depends on the specific form of hemoglobin which is present, or whether the red cells are intact or lysed, on the operating field strength, on the type of signal (that is, spin echo or gradient echo), and on contrast (that is, T1- or T2-weighing). The appearance of hemorrhage also depends on the compartment of the brain involved---subarachnoid, subdural, or intraparenchymal. Finally, for parenchymal hematomas, different zones may be defined from the inner core to the outer rim which all vary in appearance depending on field strength and imaging technique

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

    Infection with the aquatic rhabdovirus Viral hemorrhagic septicemia virus (VHSV) genogroup IVa results in high mortality in Pacific herring (Clupea pallasii) and is hypothesized to be a potential limiting factor for herring recovery. To investigate anti-viral immunity in the Pacific herring, four immune response genes were identified: the myxovirus resistance (Clpa-Mx), a major histocompatibility complex IB (named Clpa-UAA.001), the inducible immunoproteosome subunit 9 (Clpa-PSMB9) and the neutrophil chemotactic factor (Clpa-LECT2). Reverse transcriptase quantitative PCR (RT-qPCR) assays were developed based on these gene sequences to investigate the host immune response to acute VHSV infection following both injection and immersion challenge. Virus levels were measured by both plaque assay and RT-qPCR and peaked at day 6 during the 10-day exposure period for both groups of fish. The interferon stimulated genes (Clpa-Mx, −UAA.001, and −PSMB9) were significantly up-regulated in response to VHSV infection at both 6 and 10 days post-infection in both spleen and fin. Results from this study indicate that Pacific herring mount a robust, early antiviral response in both fin and spleen tissues. The immunological tools developed in this study will be useful for future studies to investigate antiviral immunity in Pacific herring.

  5. Computed tomography in intracranial hemorrhage in leukemia

    In tracranial hemorrhage in leukemia was clinicopathologically studied in 62 cases of autopsy materials, with special attention paid to a morphological comparison of CT images with pathological findings. Intracranial hemorrhage was found in 32 of the 62 leukemic patients (51.6%), and in 13 of these patients (21.0%) it was responsible for death. Leukemic intracranial hemorrhage occurred more often in the acute leukemic type than in the chronic type, and even more often in younger leukemic patinents; it was pathologically characterized by multiple lesions in the white matter of the cerebral hemisphere, prone to combination with SAH or SDH. The hemorrhages could be divided into five types: (1) scattered small hemorrhagic type, (2) hematoma type, (3) fusion type (large hemorrhage composed of assembled small hemorrhages), (4) SAH type, and (5) SDH type. Among these types, the fusion type was considered to be characteristic of leukemia. CT was undertaken in 5 pathologically proven cases, with findings of the scattered small hemorrhagic type in 1, of the SDH type in 3, and of the fusion type in 1. Yet, one case with scattered small hemorrhages and two cases with SDH failed to be detected by CT. However, one case with a typical fusion hemorrhage was found to have multiple, irregular, high-density areas with surrounding edema and a mass effect as well as pathological findings. Therefore, a large-fusion hemorrhage, which is one of the most characteristic types of leukemic intracranial hemorrhage, could be demonstrated as distinctive CT images which reflected neuropathological findings. On the other hand, small parenchymal hemorrhages and relatively thin subdural hemorrhages could not be detected by CT. In conclusion, it seems that CT has value in the diagnosis of intracranial hemorrhage in leukemia. (J.P.N.)

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

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

    Purpose: There is no gold-standard regarding the diagnostic work-up and therapy of an acute gastrointestinal (GI) hemorrhage. In most cases endoscopy provides the diagnosis but in a low percentage this modality is not feasible or negative. Purpose of this study was to evaluate the role of multi-phase Multi-Slice-Computertomography (MSCT) as a modality to diagnose and locate the site of acute GI hemorrhage in case of unfeasible or technically difficult endoscopy. Materials and methods: 58 patients, presenting with clinical signs of lower GI hemorrhage, were examined through a 24-month period. Preliminary endoscopy was either negative or unfeasible. Images were obtained with a four-detector row CT with an arterial (4 x 1 mm collimation, 0.8 mm increment, 1.25 mm slice width, 120 kV, 165 mAs) and portal venous series (4 x 2,5 mm collimation, 2 mm increment, 3 mm slice width, 120 kV, 165 mAs). Time interval between endoscopy and CT varied between 30 minutes and 3 hours. The results of the MSCT were correlated with clinical course and surgical or endoscopical treatment. Results: 20 of the 58 patients (34%) undergoing MSCT had a bleeding site identified, thus providing decisive information for the following intervention. In case of a following therapeutic intervention there was 100% correlation regarding the bleeding site. In 38 of the 58 patients (66%), a bleeding site was not identified by MSCT. Twenty of these 38 patients (53%) were stable and required no further treatment. In 18 of these 38 patients further interventional therapy was required due to continuing hemorrhage and in all of those patients the bleeding site was detected by intervention. (orig.)

    Full Text Available Crimean Congo hemorrhagic fever virus (CCHFV is a geographically widespread pathogen that causes severe hemorrhagic fever with high mortality. Although it is primarily zoonosis, sporadic cases and outbreaks of CCHF affecting humans do occur. The disease is endemic in many countries in Africa, Europe and Asia, and during 2002-2006, is has been reported in Turkey. People become infected through tick bites (especially Hyalomma spp., by crushing infected ticks, after contact with a patient with CCHF during the acute phase of infection, or by contact with blood or tissues from viremic livestock.

  10. Idiopathic portal hypertension

    To describe the radiologic findings of idiopathic portal hypertension and to find the points of differentiation between idiopathic portal hypertension and liver cirrhosis. Four portograms in five patients who for four years had suffered from pathologically confirmed idiopathic portal hypertension were retrospectively analyzed and compared with a portogram obtained from a control subject with liver cirrhosis. Portographic finding s of idiopathic portal hypertension were paucity of medium-sized portal branches, irregular and obtuse-angled division of peripheral branches, abrupt interruption and an avascular area beneath the liver margin. A portogram of idiopathic portal hypertension may be useful in differentiation this and liver cirrhosis
