    2012-01-01

    Viral hemorrhagic septicemia (VHS) is one of the most important viral diseases of finfish worldwide. In the past, VHS was thought to affect mainly rainbow trout Oncorhynchus mykiss reared at freshwater facilities in Western Europe where it was known by various names including Egtved disease and infectious kidney swelling and liver degeneration (Wolf 1988). Today, VHS is known as an important source of mortality for cultured and wild fish in freshwater and marine environments in several regions of the northern hemisphere (Dixon 1999; Gagné et al. 2007; Kim and Faisal 2011; Lumsden et al. 2007; Marty et al. 1998, 2003; Meyers and Winton 1995; Skall et al. 2005b; Smail 1999; Takano et al. 2001). Viral hemorrhagic septicemia is caused by the fish rhabdovirus, viral hemorrhagic septicemia virus (VHSV), a member of the genus Novirhabdovirus of the family Rhabdoviridae

    Rabbit antisera against viral hemorrhagic septicemia virus (VHSV) produced by two immunization procedures were compared for neutralization and immunochemical properties against homologous and heterologous strains. The VHSV isolate used as the immunogen was a member of a serogroup not neutralized...... by previously available antisera. The results from this study suggested that frequent intravenous (IV) injections of rabbits with viral antigens were superior to adjuvant-mediated, combined subcutaneous and intraperitoneal (SC/IP) injections for the production of neutralizing antisera. All IV injected rabbits...... produced high neutralization titers against the homologous VHSV isolate but not against an isolate from a different serogroup. The SC/IP injected rabbits had no significant neutralization titers against either the homologous VHSV strain or two isolates of a heterologous VHSV strain. Sera from all injected...

    The plasma of Pacific herring Clupea pallasii that survived laboratory-induced viral hemorrhagic septicemia (VHS) epizootics contained humoral substances that, when injected into naive animals, conferred passive immunity against the disease. Among groups exposed to viral hemorrhagic septicemia virus (VHSV), injection of donor plasma from VHS survivors resulted in significantly greater survival (50%) and significantly lower tissue titers (1.5 x 10(5) plaque-forming units [PFU]/g) than the injection of plasma from VHSV-naive donors (6% survival; 3.7 x 10(6) PFU/g). Additionally, the magnitude of the protective immune response increased during the postexposure period; plasma that was collected from survivors at 123 d postexposure (931 degree-days) provided greater protection than plasma collected from survivors at 60 d postexposure (409 degree-days). These results provide proof of concept that the VHSV exposure history of Pacific herring populations can be determined post hoc; furthermore, the results can be used as the foundation for developing additional high-throughput diagnostic techniques that may be effective at quantifying herd immunity and forecasting the potential for future VHS epizootics in populations of wild Pacific herring.

  6. Phylogeny of the Viral Hemorrhagic Septicemia Virus in European Aquaculture.

    Full Text Available One of the most valuable aquaculture fish in Europe is the rainbow trout, Oncorhynchus mykiss, but the profitability of trout production is threatened by a highly lethal infectious disease, viral hemorrhagic septicemia (VHS, caused by the VHS virus (VHSV. For the past few decades, the subgenogroup Ia of VHSV has been the main cause of VHS outbreaks in European freshwater-farmed rainbow trout. Little is currently known, however, about the phylogenetic radiation of this Ia lineage into subordinate Ia clades and their subsequent geographical spread routes. We investigated this topic using the largest Ia-isolate dataset ever compiled, comprising 651 complete G gene sequences: 209 GenBank Ia isolates and 442 Ia isolates from this study. The sequences come from 11 European countries and cover the period 1971-2015. Based on this dataset, we documented the extensive spread of the Ia population and the strong mixing of Ia isolates, assumed to be the result of the Europe-wide trout trade. For example, the Ia lineage underwent a radiation into nine Ia clades, most of which are difficult to allocate to a specific geographic distribution. Furthermore, we found indications for two rapid, large-scale population growth events, and identified three polytomies among the Ia clades, both of which possibly indicate a rapid radiation. However, only about 4% of Ia haplotypes (out of 398 occur in more than one European country. This apparently conflicting finding regarding the Europe-wide spread and mixing of Ia isolates can be explained by the high mutation rate of VHSV. Accordingly, the mean period of occurrence of a single Ia haplotype was less than a full year, and we found a substitution rate of up to 7.813 × 10-4 nucleotides per site per year. Finally, we documented significant differences between Germany and Denmark regarding their VHS epidemiology, apparently due to those countries' individual handling of VHS.

    Viral hemorrhagic septicemia (VHS) in rainbow trout Oncorhynchus mykiss is caused by VHS virus (VHSV), which belongs to the rhabdovirus family. Among the different strategies for immunizing fish with a recombinant vaccine, genetic immunization has recently proven to be highly effective. To further...... investigate the potential for protecting fish against VHS by DNA vaccination, experiments were conducted to determine the amount of plasmid DNA needed for induction of protective immunity. The time to onset of immunity and the duration of protection following administration of a protective vaccine dose were...... serologically different from the isolate used for vaccine development. Following administration of 1 mug of a DNA vaccine, significant protection against VHS was observed in the fish as early as 8 d postvaccination. At 168 d postvaccination, the fish had increased in size by a factor of 10 and protection...

  8. Detection of viral hemorrhagic septicemia virus

    Winton, James; Kurath, Gael; Batts, William

    2007-01-01

    Viral hemorrhagic septicemia virus (VHSV) is considered to be one of the most important viral pathogens of finfish and is listed as reportable by many nations and international organizations (Office International des Epizooties 2006). Prior to 1988, VHSV was thought to be limited to Europe (Wolf 1988; Smail 1999). Subsequently, it was shown that the virus is endemic among many marine and anadromous fish species in both the Pacific and Atlantic Oceans (Meyers and Winton 1995; Skall et al. 2005). Genetic analysis reveals that isolates of VHSV can be divided into four genotypes that generally correlate with geographic location with the North American isolates generally falling into VHSV Genotype IV (Snow et al. 2004). In 2005-2006, reports from the Great Lakes region indicated that wild fish had experienced disease or, in some cases, very large die-offs from VHSV (Elsayed et al. 2006, Lumsden et al. 2007). The new strain from the Great Lakes, now identified as VHSV Genotype IVb, appears most closely related to isolates of VHSV from mortalities that occurred during 2000-2004 in rivers and near-shore areas of New Brunswick and Nova Scotia, Canada (Gagne et al. 2007). The type IVb isolate found in the Great Lakes region is the only strain outside of Europe that has been associated with significant mortality in freshwater species.

  9. Principles underlying the epizootiology of viral hemorrhagic septicemia in Pacific herring and other fishes throughout the North Pacific Ocean

    Hershberger, Paul K.; Garver, Kyle A.; Winton, James R.

    2016-01-01

    Although viral hemorrhagic septicemia virus (VHSV) typically occurs at low prevalence and intensity in natural populations of Pacific herring (Clupea pallasii) and other marine fishes in the Northeast Pacific Ocean, epizootics of the resulting disease (VHS) periodically occur, often in association with observed fish kills. Here we identify a list of principles, based on a combination of field studies, controlled laboratory experiments, and previously unpublished observations, that govern the epizootiology of VHS in Pacific herring. A thorough understanding of these principles provides the basis for identifying risk factors that predispose certain marine fish populations to VHS epizootics, including the lack of population resistance, presence of chronic viral carriers in a population, copious viral shedding by infected individuals, cool water temperatures, limited water circulation patterns, and gregarious host behavioral patterns. Further, these principles are used to define the epizootiological stages of the disease in Pacific herring, including the susceptible (where susceptible individuals predominate a school or subpopulation), enzootic (where infection prevalence and intensity are often below the limits of reasonable laboratory detection), disease amplification (where infection prevalence and intensity increase rapidly), outbreak (often accompanied by host mortalities with high virus loads and active shedding), recovery (in which the mortality rate and virus load decline owing to an active host immune response), and refractory stages (characterized by little or no susceptibility and where viral clearance occurs in most VHS survivors). In addition to providing a foundation for quantitatively assessing the potential risks of future VHS epizootics in Pacific herring, these principles provide insights into the epizootiology of VHS in other fish communities where susceptible species exist.

  10. Molecular diagnosis of infectious hematopoietic necrosis and viral hemorrhagic septicemia

    Winton, James R.; Einer-Jensen, Katja

    2002-01-01

    The fish rhabdoviruses, infectious hematopoietic necrosis virus (IHNV) and viral hemorrhagic septicemia virus (VHSV), cause extensive losses among salmon and trout in several areas of the world (Bootland and Leong, 1999; Smail, 1999; Wolf, 1988). Historically, IHNV was endemic among wild anadromous salmonids in the western portion of North America, but the virus has spread to stocks of cultured rainbow trout (Oncorhynchus mykiss) in the United States, Asia and Western Europe, probably as a result of the movement of infected fish or eggs (Winton, 1991). Prior to 1989, VHSV was thought to be largely restricted to freshwater fishes in Western Europe (Wolf, 1988); however, in the last decade, VHSV has been isolated from an increasing number of free-living marine fish species in the North Pacific and North Atlantic Oceans (Dixon et al., 1997; Dixon, 1999; Kent et al., 1998; Meyers and Winton, 1995; Meyers et al., 1999; Mortensen et al., 1999; Smail; 2000, Takano et al., 2000). These findings have lead to the conclusion that both viruses are principally endemic among marine or anadromous fish species, but have established themselves in freshwater among cultured salmonids where their effects are most frequently observed.

  11. Viral tropism and pathology associated with viral hemorrhagic septicemia in larval and juvenile Pacific herring

    Viral hemorrhagic septicemia virus (VHSV) genotype IVa causes mass mortality in wild Pacific herring, a species of economic value, in the Northeast Pacific Ocean. Young of the year herring are particularly susceptible and can be carriers of the virus. To understand its pathogenesis, tissue and cellular tropisms of VHSV in larval and juvenile Pacific herring were investigated with immunohistochemistry, transmission electron microscopy, and viral tissue titer. In larval herring, early viral tropism for epithelial tissues (6d post-exposure) was indicated by foci of epidermal thickening that contained heavy concentrations of virus. This was followed by a cellular tropism for fibroblasts within the fin bases and the dermis, but expanded to cells of the kidney, liver, pancreas, gastrointestinal tract and meninges in the brain. Among wild juvenile herring that underwent a VHS epizootic in the laboratory, the disease was characterized by acute and chronic phases of death. Fish that died during the acute phase had systemic infections in tissues including the submucosa of the gastrointestinal tract, spleen, kidney, liver, and meninges. The disease then transitioned into a chronic phase that was characterized by the appearance of neurological signs including erratic and corkscrew swimming and darkening of the dorsal skin. During the chronic phase viral persistence occurred in nervous tissues including meninges and brain parenchymal cells and in one case in peripheral nerves, while virus was mostly cleared from the other tissues. The results demonstrate the varying VHSV tropisms dependent on the timing of infection and the importance of neural tissues for the persistence and perpetuation of chronic infections in Pacific herring.

    An acute hemorrhagic septicemia in a captive ground-hornbill (Bucorvus abyssinicus) is reported. Aeromonas hydrophila was isolated from lungs, liver, kidney, and intestines. Postmortem lesions were characterized by hemorrhages in the internal organs. Microscopically, necrotic lesions were found in the liver, lungs, and kidney. Factors that might have contributed to the clinical disease condition are discussed.

    In British Columbia, Canada (BC), aquaculture of finfish in ocean netpens has the potential for pathogen transmission between wild and farmed species due to the sharing of an aquatic environment. Viral hemorrhagic septicemia virus (VHSV) is enzootic in BC and causes serious disease in wild Pacific herring, Clupea pallasii, which often enter and remain in Atlantic salmon, Salmo salar, netpens. Isolation of VHSV from farmed Atlantic salmon has been previously documented, but the effects on the health of farmed salmon and the wild fish sharing the environment are unknown. To determine their susceptibility, Atlantic salmon were exposed to a pool of 9 isolates of VHSV obtained from farmed Atlantic salmon in BC by IP-injection or by waterborne exposure and cohabitation with diseased Pacific herring. Disease intensity was quantified by recording mortality, clinical signs, histopathological changes, cellular sites of viral replication, expression of interferon-related genes, and viral tissue titers. Disease ensued in Atlantic salmon after both VHSV exposure methods. Fish demonstrated gross disease signs including darkening of the dorsal skin, bilateral exophthalmia, light cutaneous hemorrhage, and lethargy. The virus replicated within endothelial cells causing endothelial cell necrosis and extensive hemorrhage in anterior kidney. Infected fish demonstrated a type I interferon response as seen by up-regulation of genes for IFNα, Mx, and ISG15. In a separate trial infected salmon transmitted the virus to sympatric Pacific herring. The results demonstrate that farmed Atlantic salmon can develop clinical VHS and virus can persist in the tissues for at least 10 weeks. Avoiding VHS epizootics in Atlantic salmon farms would limit the potential of VHS in farmed Atlantic salmon, the possibility for further host adaptation in this species, and virus spillback to sympatric wild fishes.

    Full Text Available Abstract Background Viral hemorrhagic septicemia virus (VHSV is a highly contagious viral disease of fresh and saltwater fish worldwide. VHSV caused several large scale fish kills in the Great Lakes area and has been found in 28 different host species. The emergence of VHS in the Great Lakes began with the isolation of VHSV from a diseased muskellunge (Esox masquinongy caught from Lake St. Clair in 2003. VHSV is a member of the genus Novirhabdovirus, within the family Rhabdoviridae. It has a linear single-stranded, negative-sense RNA genome of approximately 11 kbp, with six genes. VHSV replicates in the cytoplasm and produces six monocistronic mRNAs. The gene order of VHSV is 3'-N-P-M-G-NV-L-5'. This study describes molecular characterization of the Great Lakes VHSV strain (MI03GL, and its phylogenetic relationships with selected European and North American isolates. Results The complete genomic sequences of VHSV-MI03GL strain was determined from cloned cDNA of six overlapping fragments, obtained by RT-PCR amplification of genomic RNA. The complete genome sequence of MI03GL comprises 11,184 nucleotides (GenBank GQ385941 with the gene order of 3'-N-P-M-G-NV-L-5'. These genes are separated by conserved gene junctions, with di-nucleotide gene spacers. The first 4 nucleotides at the termini of the VHSV genome are complementary and identical to other novirhadoviruses genomic termini. Sequence homology and phylogenetic analysis show that the Great Lakes virus is closely related to the Japanese strains JF00Ehi1 (96% and KRRV9822 (95%. Among other novirhabdoviruses, VHSV shares highest sequence homology (62% with snakehead rhabdovirus. Conclusion Phylogenetic tree obtained by comparing 48 glycoprotein gene sequences of different VHSV strains demonstrate that the Great Lakes VHSV is closely related to the North American and Japanese genotype IVa, but forms a distinct genotype IVb, which is clearly different from the three European genotypes.

  19. Kinetics of viral shedding provide insights into the epidemiology of viral hemorrhagic septicemia in Pacific herring

    Hershberger, Paul K.; Gregg, Jacob L.; Winton, James R.; Grady, Courtney; Collins, Rachael

    2010-01-01

    Losses from infectious diseases are an important component of natural mortality among marine fish species, but factors controlling the ecology of these diseases and their potential responses to anthropogenic changes are poorly understood. We used viral hemorrhagic septicemia virus (VHSV) and a laboratory stock of Pacific herring Clupea pallasii to investigate the kinetics of viral shedding and its effect on disease transmission and host mortality. Outbreaks of acute disease, accompanied by mortality and viral shedding, were initiated after waterborne exposure of herring to concentrations of VHSV as low as 101 plaque-forming units (pfu) ml–1. Shed virus in flow-through tanks was first detected 4 to 5 d post-exposure, peaked after 6 to 10 d, and was no longer detected after 16 d. Shedding rates, calculated from density, flow and waterborne virus titer reached 1.8 to 5.0 × 108 pfu fish–1 d–1. Onset of viral shedding was dose-dependent and preceded initial mortality by 2 d. At 21 d, cumulative mortality in treatment groups ranged from 81 to 100% and was dependent not on challenge dose, but on the kinetics and level of viral shedding by infected fish in the tank. Possible consequences of the viral shedding and disease kinetics are discussed in the context of epizootic initiation and perpetuation among populations of wild Pacific herring.

    Full Text Available The present investigation was executed to study the sero-surveillance of hemorrhagic septicemia (HS in buffaloes and cattle in district Dera-Ghazi-Khan, Punjab, Pakistan. The average geometric mean titers (GMT recorded against HS in diseased buffaloes and cattle were 5.7 and 6.1, respectively. The morbidity, mortality and case fatality rates were 57.58, 52.30 and 90.83% in young buffalo calves; and 3.17, 1.92 and 60.65%, in adult buffaloes, respectively. Whereas, in case of young cattle calves, morbidity, mortality and case fatality rates were 8.63, 5.27 and 61.11%, respectively. While in adult cattle, morbidity, mortality and case fatality rates were 4.83, 2.18 and 45.23%, respectively. The present study revealed that the mortality, morbidity and case fatality rates due to HS were greater in young calves than the adults both in buffaloes and cattle. Furthermore, buffaloes were found to be more susceptible to the disease than the cattle.

  1. Emergence and resurgence of the viral hemorrhagic septicemia virus (Novirhabdovirus, Rhabdoviridae, Mononegavirales

    2011-01-01

    Full Text Available Viral hemorrhagic septicemia virus (VHSV is one of the most serious pathogens of finfish worldwide in terms of its wide host-range, pathogenicity, disease course, and mortality rates. The disease was first documented in the 1930s in Europe in association with heavy losses in rainbow. Data collected over 50 years show that VHSV is a virus of marine origin: its ability to alternate between marine and freshwater environments remains an enigma which requires further investigation. In 2003, VHSV invaded the Laurentian Great Lakes basin causing devastating losses. VHSV is believed to have negative impacts on a number of important Atlantic, Pacific, and Great Lakes fish species. Phylogenetic analysis has offered clues into the geographic and host range of the virus, but sporadic outbreaks of the disease in uncommon locations have imparted unforeseen challenges in delineating the virus’ regional distribution. The virus’ ability to gain access to aquaculture farms has also positioned it as a disease of utmost priority once detected in these settings. Current diagnostic methods, while greatly improved, are hampered by the variability of disease course among susceptible species. In general, VHSV causes severe degeneration in the hematopoietic tissues of affected fish. Based on historical and current data, it is feared that VHSV will continue to mutate, expand to other geographic areas, and infect new host species. As a result, immediate international attention and coordination of efforts are needed. The objective of this review article is to provide an updated synopsis on the current status of VHSV epizootiology and pathogenicity.

    Full Text Available Viral hemorrhagic septicemia virus (VHSV infects a wide range of marine fish species. To study the occurrence of VHSV in wild marine fish populations in Norwegian coastal waters and fjord systems a total of 1927 fish from 39 different species were sampled through 5 research cruises conducted in 2009 to 2011. In total, VHSV was detected by rRT-PCR in twelve samples originating from Atlantic herring (Clupea harengus, haddock (Melanogrammus aeglefinus, whiting (Merlangius merlangus and silvery pout (Gadiculus argenteus. All fish tested positive in gills while four herring and one silvery pout also tested positive in internal organs. Successful virus isolation in cell culture was only obtained from one pooled Atlantic herring sample which shows that today's PCR methodology have a much higher sensitivity than cell culture for detection of VHSV. Sequencing revealed that the positive samples belonged to VHSV genotype Ib and phylogenetic analysis shows that the isolate from Atlantic herring and silvery pout are closely related. All positive fish were sampled in the same area in the northern county of Finnmark. This is the first detection of VHSV in Atlantic herring this far north, and to our knowledge the first detection of VHSV in silvery pout. However, low prevalence of VHSV genotype Ib in Atlantic herring and other wild marine fish are well known in other parts of Europe. Earlier there have been a few reports of disease outbreaks in farmed rainbow trout with VHSV of genotype Ib, and our results show that there is a possibility of transfer of VHSV from wild to farmed fish along the Norwegian coast line. The impact of VHSV on wild fish is not well documented.

    It has been previously demonstrated that even though the fin bases constitute the main portal of entry of viral hemorrhagic septicemia virus (VHSV) in rainbow trout (Oncorhynchus mykiss), an important number of chemokine genes are up-regulated in the gills upon bath exposure to the virus. Because chemokines mediate the recruitment of leukocytes through the action of specific chemokine receptors, in the current study, we have studied the transcription of several immune genes in response to a VHSV bath infection in the gills, focusing both on chemokine receptor genes and on genes characteristic of distinct leukocyte populations such as IgM, IgD, IgT, CD4, CD8, perforin and MHC-II. We have studied the response to the virus in naïve fish as well as in fish that had been previously intramuscularly (i.m.) injected with a VHSV DNA vaccine. Additionally, we have sorted both IgM(+) and CD8(+) cells from the gills of naïve and infected animals to study some of these up-regulated genes in specific leukocyte populations. Our results indicate that despite the low replication level, VHSV provokes an up-regulation of IgM, IgT, CD3 and perforin transcription together with the up-regulation of CCR7, CCR9, CXCR3B and CXCR4 mRNA levels. Interestingly, MHC-II mRNA was up-regulated and CCR7 was down-modulated in IgM(+) cells from infected gills, whereas perforin, CCR7 and CXCR4 mRNA levels were higher in sorted CD8(+) cells from infected animals. Surprisingly, when fish had been previously injected with either the empty plasmid or the VHSV DNA vaccine, these up-regulations in immune gene transcription were no longer observed. Our results point to the gills as an important site for innate and acquired viral defense. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Viral hemorrhagic septicemia virus (VHSV) is a rhabdovirus found in fish from oceans of the northern hemisphere and freshwaters of Europe. It has caused extensive losses of cultured and wild fish and has become established in the North American Great Lakes. Large die-offs of wild fish in the Great Lakes due to VHSV have alarmed the public and provoked government attention on the introduction and spread of aquatic animal pathogens in freshwaters. We investigated the relations between VHSV dispersion and shipping and boating activity in the Great Lakes by sampling fish and water at sites that were commercial shipping harbors, recreational boating centers, and open shorelines. Fish and water samples were individually analyzed for VHSV using quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and cell culture assays. Of 1,221 fish of 17 species, 55 were VHSV positive with highly varied qRT-PCR titers (1 to 5,950,000 N gene copies). The detections of VHSV in fish and water samples were closely associated and the virus was detected in 21 of 30 sites sampled. The occurrence of VHSV was not related to type of site or shipping related invasion hotspots. Our results indicate that VHSV is widely dispersed in the Great Lakes and is both an enzootic and epizootic pathogen. We demonstrate that pathogen distribution information could be developed quickly and is clearly needed for aquatic ecosystem conservation, management of affected populations, and informed regulation of the worldwide trade of aquatic organisms.

  7. In vitro infection of salmonid epidermal tissues by infectious hematopoietic necrosis virus and viral hemorrhagic septicemia virus

    1992-01-01

    The ability of two rhabdoviruses, infectious hematopoietic necrosis virus (IHNV) and viral hemorrhagic septicemia virus (VHSV), to infect fish skin was investigated by in vitro infection of excised tissues. Virus replication was determined by plaque assay of homogenized tissue extracts, and the virus antigen was detected by immunohistology of tissue sections. Gill, fin, and ventral abdominal skin tissues of rainbow trout Oncorhynchus mykiss that had been infected in vitro with a virulent strain of IHNV (193–110) produced substantial increases in virus titer within 24 h. Titers continued to increase up until day 3 of incubation; by this time, virus had increased 1,000-fold or more. This increase in IHNV titer occurred in epidermal tissues of fingerlings and of older fish. In another experiment, IHNV replicated in excised rainbow trout tissues whether the fish had been subject to prior infection with a virulent strain of IHNV (Western Regional Aquaculture Consortium isolate) or whether the fish had been infected previously with an attenuated strain of the virus (Nan Scott Lake, with 100 passes in culture). A virulent strain of VHSV (23/75) replicated effectively in excised gill tissues and epidermal tissues of rainbow trout and chinook salmon O. tshawytscha; however, the avirulent North American strain of VHSV (Makah) replicated poorly or not at all.

    Viral hemorrhagic septicemia virus (VHSV) has been reported to be stable in both fresh as well as seawater, suggesting that VHSV exists in natural aquatic environments and might have an effect on the wild and cultured fish. However, VHSV is below the detectable limits of laboratory tests in natural seawater. In this study, a two-step ultrafiltration (UF) procedure was used to concentration of VHSV in seawater, providing samples that were tested for infectivity by cell culture and the presence of VHSV by quantitative reverse transcriptase PCR (qRT-PCR) methods. Overall, VHSV was approximately concentrated 100-1000 times in 1, 5 and 10 L, seawater volumes respectively: from 2.81×10(6) to 6.53×10(7)/mL and 10(3.3) to 10(3.8)TCID50/mL prior to the UF procedure, to 3.78×10(8), 1.16 × 10(11), and 9.12 × 10(10)/mL after the procedure. This is the first report of concentrating VHSV using an UF method that was specifically designed for seawater samples. In addition, the two-step UF procedure appears to be compatible with viral cell culture and qRT-PCR methods. Copyright © 2015 Elsevier B.V. All rights reserved.

    The susceptibility of yellow perch Perca flavescens, rainbow trout Oncorhynchus mykiss, Chinook salmon O. tshawytscha, koi Cyprinus carpio koi, and Pacific herring Clupea pallasii to 4 strains of viral hemorrhagic septicemia virus (VHSV) was assessed. Fish were challenged via intraperitoneal injection with high (1 × 106 plaque-forming units, PFU) and low (1 × 103 PFU) doses of a European strain (genotype Ia), and North American strains from the West coast (genotype IVa), Great Lakes (genotype IVb), and the East coast (genotype IVc). Pacific herring were exposed to the same VHSV strains, but at a single dose of 5 × 103 PFU ml-1 by immersion in static seawater. Overall, yellow perch were the most susceptible, with cumulative percent mortality (CPM) ranging from 84 to 100%, and 30 to 93% in fish injected with high or low doses of virus, respectively. Rainbow trout and Chinook salmon experienced higher mortalities (47 to 98% CPM) after exposure to strain Ia than to the other virus genotypes. Pacific herring were most susceptible to strain IVa with an average CPM of 80% and moderately susceptible (42 to 52% CPM) to the other genotypes. Koi had very low susceptibility (≤5.0% CPM) to all 4 VHSV strains. Fish tested at 7 d post challenge were positive for all virus strains, with yellow perch having the highest prevalence and concentrations of virus, and koi the lowest. While genotype Ia had higher virulence in salmonid species, there was little difference in virulence or host-specificity between isolates from subtypes IVa, IVb, and IVc.

    Viral hemorrhagic septicemia virus (VHSV) is a fish rhabdovirus that causes disease in a broad range of marine and freshwater hosts. The known geographic range includes the Northern Atlantic and Pacific Oceans, and recently it has invaded the Great Lakes region of North America. The goal of this work was to characterize genetic diversity of Great Lakes VHSV isolates at the early stage of this viral emergence by comparing a partial glycoprotein (G) gene sequence (669 nt) of 108 isolates collected from 2003 to 2009 from 31 species and at 37 sites. Phylogenetic analysis showed that all isolates fell into sub-lineage IVb within the major VHSV genetic group IV. Among these 108 isolates, genetic diversity was low, with a maximum of 1.05% within the 669 nt region. There were 11 unique sequences, designated vcG001 to vcG011. Two dominant sequence types, vcG001 and vcG002, accounted for 90% (97 of 108) of the isolates. The vcG001 isolates were most widespread. We saw no apparent association of sequence type with host or year of isolation, but we did note a spatial pattern, in which vcG002 isolates were more prevalent in the easternmost sub-regions, including inland New York state and the St. Lawrence Seaway. Different sequence types were found among isolates from single disease outbreaks, and mixtures of types were evident within 2 isolates from individual fish. Overall, the genetic diversity of VHSV in the Great Lakes region was found to be extremely low, consistent with an introduction of a new virus into a geographic region with previously naive host populations.

    Viral hemorrhagic septicemia virus (VHSV) is an emerging pathogen that causes mass mortality in multiple fish species. In 2007, the Great Lakes freshwater strain, type IVb, caused a large die-off of freshwater drum (Aplodinotus grunniens) in Lake Winnebago, Wisconsin, USA. To evaluate the persistence and transmission of VHSV, freshwater drum from Lake Winnebago were tested for antibodies to the virus using recently developed virus neutralization (VN) and enzyme-linked immunosorbent (ELISA) assays. Samples were also tested by real-time reverse transcription-PCR (rRT-PCR) to detect viral RNA. Of 548 serum samples tested, 44 (8.03%) were positive by VN (titers ranging from 1:16 to 1:1,024) and 45 (8.21%) were positive by ELISA, including 7 fish positive by both assays. Antibody prevalence increased with age and was higher in one northwestern area of Lake Winnebago than in other areas. Of 3,864 tissues sampled from 551 fish, 1 spleen and 1 kidney sample from a single adult female fish collected in the spring of 2012 tested positive for VHSV by rRT-PCR, and serum from the same fish tested positive by VN and ELISA. These results suggest that VHSV persists and viral transmission may be active in Lake Winnebago even in years following outbreaks and that wild fish may survive VHSV infection and maintain detectable antibody titers while harboring viral RNA. Influxes of immunologically naive juvenile fish through recruitment may reduce herd immunity, allow VHSV to persist, and drive superannual cycles of transmission that may sporadically manifest as fish kills.

    Viral hemorrhagic septicemia virus (VHSV) is a target of surveillance by many state and federal agencies in the United States. Currently, the detection of VHSV relies on virus isolation, which is lethal to fish and indicates only the current infection status. A serological method is required to ascertain prior exposure. Here, we report two serologic tests for VHSV that are nonlethal, rapid, and species independent, a virus neutralization (VN) assay and a blocking enzyme-linked immunosorbent assay (ELISA). The results show that the VN assay had a specificity of 100% and sensitivity of 42.9%; the anti-nucleocapsid-blocking ELISA detected nonneutralizing VHSV antibodies at a specificity of 88.2% and a sensitivity of 96.4%. The VN assay and ELISA are valuable tools for assessing exposure to VHSV.

    Full Text Available Viral Hemorrhagic Septicemia virus (VHSv is one of the world's most serious fish pathogens, infecting >80 marine, freshwater, and estuarine fish species from Eurasia and North America. A novel and especially virulent strain - IVb - appeared in the Great Lakes in 2003, has killed many game fish species in a series of outbreaks in subsequent years, and shut down interstate transport of baitfish. Cell culture is the diagnostic method approved by the USDA-APHIS, which takes a month or longer, lacks sensitivity, and does not quantify the amount of virus. We thus present a novel, easy, rapid, and highly sensitive real-time quantitative reverse transcription PCR (qRT-PCR assay that incorporates synthetic competitive template internal standards for quality control to circumvent false negative results. Results demonstrate high signal-to-analyte response (slope = 1.00±0.02 and a linear dynamic range that spans seven orders of magnitude (R(2 = 0.99, ranging from 6 to 6,000,000 molecules. Infected fishes are found to harbor levels of virus that range to 1,200,000 VHSv molecules/10(6 actb1 molecules with 1,000 being a rough cut-off for clinical signs of disease. This new assay is rapid, inexpensive, and has significantly greater accuracy than other published qRT-PCR tests and traditional cell culture diagnostics.

    The recently discovered strain of viral hemorrhagic septicemia virus, VHSV-IVb, represents an example of the introduction of an extremely pathogenic rhabdovirus capable of infecting a wide variety of new fish species in a new host-environment. The goal of the present study was to delineate the expression kinetics of key genes in the innate immune response relative to the very early stages of VHSV-IVb infection using the yellow perch (Perca flavescens) as a model. Administration of VHSV-IVb by IP-injection into juvenile yellow perch resulted in 84% cumulative mortality, indicating their high susceptibility to this disease. In fish sampled in the very early stages of infection, a significant up-regulation of Mx gene expression in the liver, as well as IL-1β and SAA activation in the head kidney, spleen, and liver was directly correlated to viral load. The potential down-regulation of Mx in the hematopoietic tissues, head kidney and spleen, may represent a strategy utilized by the virus to increase replication.

    Viral hemorrhagic septicemia virus (VHSV), belonging to the genus Novirhabdovirus in the family of Rhabdoviridae, causes a highly contagious disease of fresh and saltwater fish worldwide. Recently, a novel genotype of VHSV, designated IVb, has invaded the Great Lakes in North America, causing large-scale epidemics in wild fish. An efficient reverse genetics system was developed to generate a recombinant VHSV of genotype IVb from cloned cDNA. The recombinant VHSV (rVHSV) was comparable to the parental wild-type strain both in vitro and in vivo, causing high mortality in yellow perch (Perca flavescens). A modified recombinant VHSV was generated in which the NV gene was substituted with an enhanced green fluorescent protein gene (rVHSV-ΔNV-EGFP), and another recombinant was made by inserting the EGFP gene into the full-length viral clone between the P and M genes (rVHSV-EGFP). The in vitro replication kinetics of rVHSV-EGFP was similar to rVHSV; however, the rVHSV-ΔNV-EGFP grew 2 logs lower. In yellow perch challenges, wtVHSV and rVHSV induced 82-100% cumulative per cent mortality (CPM), respectively, whereas rVHSV-EGFP produced 62% CPM and rVHSV-ΔNV-EGFP caused only 15% CPM. No reversion of mutation was detected in the recovered viruses and the recombinant viruses stably maintained the foreign gene after several passages. These results indicate that the NV gene of VHSV is not essential for viral replication in vitro and in vivo, but it plays an important role in viral replication efficiency and pathogenicity. This system will facilitate studies of VHSV replication, virulence, and production of viral vectored vaccines.

    Pacific herring Clupea pallasi populations in Prince William Sound, Alaska, USA, declined from an estimated 9.8 x 10(7) kg in 1992 to 1.5 x 10(7) kg in 1994. To determine the role of disease in population decline, 233 Pacific herring from Prince William Sound were subjected to complete necropsy during April 1994. The North American strain of viral hemorrhagic septicemia virus (VHSV) was isolated from 11 of 233 fish (4.7%). VHSV was significantly related to myocardial mineralization, hepatocellular necrosis, submucosal gastritis, and meningoencephalitis. Ichthyophonus hoferi infected 62 of 212 (29%) fish. I. hoferi infections were associated with severe, disseminated, granulomatous inflammation and with increased levels of plasma creatine phosphokinase (CPK) and aspartate aminotransferase (AST). I. hoferi prevalence in 1994 was more than double that of most previous years (1989 to 1993). Plasma chemistry values significantly greater (p < 0.01) in males than females included albumin, total protein, cholesterol, chloride, glucose, and potassium; only alkaline phosphatase was significantly greater in females. Hypoalbuminemia was relatively common in postspawning females; other risk factors included VHSV and moderate or severe focal skin reddening. Pacific herring had more than 10 species of parasites, but they were not associated with significant lesions. Two of the parasites have not previously been described: a renal intraductal myxosporean (11% prevalence) and an intestinal coccidian (91% prevalence). Transmission electron microscopy of a solitary mesenteric lesion revealed viral particles consistent with lymphocystis virus. No fish had viral erythrocytic necrosis (VEN). Prevalence of external gross lesions and major parasites was not related to fish age, and fish that were year-lings at the time of the 1989 'Exxon Valdez' oil spill (1988 year class) had no evidence of increased disease prevalence.

    2011-01-01

    Viral hemorrhagic septicemia virus (VHSV) was first detected in the Laurentian Great Lakes in 2005 during a mortality event in the Bay of Quinte, Lake Ontario. Subsequent analysis of archived samples determined that the first known isolation of VHSV in the Laurentian Great Lakes was from a muskellunge Esox masquinongy collected in Lake St. Clair in 2003. By the end of 2008, mortality events and viral isolations had occurred in all of the Laurentian Great Lakes except Lake Superior. In 2009, a focused disease surveillance program was designed to determine whether VHSV was also present in Lake Superior. In this survey, 874 fish from 7 sites along the U.S. shoreline of Lake Superior were collected during June 2009. Collections were focused on nearshore species known to be susceptible to VHSV. All fish were dissected individually by using aseptic techniques and were tested for the presence of VHSV genetic material by use of a quantitative reverse transcription (qRT) polymerase chain reaction (PCR) targeting the viral nucleoprotein gene. Seventeen fish from two host species at two different sites tested positive at low levels for VHSV. All attempts to isolate virus in cell culture were unsuccessful. However, the presence of viral RNA was confirmed independently in five fish by using a nested PCR that targeted the glycoprotein (G) gene. Partial G gene sequences obtained from three fish were identical to the corresponding sequence from the original 2003 VHSV isolate (MI03) from muskellunge. These detections represent the earliest evidence for the presence of VHSV in Lake Superior and illustrate the utility of the highly sensitive qRT-PCR assay for disease surveillance in aquatic animals.

    Viral hemorrhagic septicemia virus (VHSV) is the rhabdovirus that causes most disease problems in farmed rainbow trout in Europe. Survivors of infection are usually immune to reinfection but as with other fish viruses, development of a modern recombinant vaccine has been complicated by the limited...... knowledge of the immune mechanisms and antigens involved in induction of immunity. Neutralizing and protective monoclonal antibodies recognize the envelope glycoprotein (G protein) which is the only viral protein known to be present on the surface of the virus particle. Immunoblotting analyses...... with monoclonal antibodies as well as with sera from immunized trout have indicated that protein conformation plays an important role in neutralization epitopes. The virus neutralizing activity often found in sera from convalescent trout is highly dependent on a poorly defined complementing activity in normal...

  2. Bacteria, phages and septicemia.

    Ausra Gaidelyte

    Full Text Available The use of phages is an attractive option to battle antibiotic resistant bacteria in certain bacterial infections, but the role of phage ecology in bacterial infections is obscure. Here we surveyed the phage ecology in septicemia, the most severe type of bacterial infection. We observed that the majority of the bacterial isolates from septicemia patients spontaneously secreted phages active against other isolates of the same bacterial strain, but not to the strain causing the disease. Such phages were also detected in the initial blood cultures, indicating that phages are circulating in the blood at the onset of sepsis. The fact that most of the septicemic bacterial isolates carry functional prophages suggests an active role of phages in bacterial infections. Apparently, prophages present in sepsis-causing bacterial clones play a role in clonal selection during bacterial invasion.

    Fish suffer, from bacteria, fungi, virus and parasites or by physical ailments. Gurami (Osphronemus gouramy), nila (Oreochromis niloticus), carp (Cyprinus carpio), catfish (Clarias sp.) were the most reported infections caused by Aeromonas are bacterial hemorrhagic septicemia or Motile Aeromonas Septicemia (MAS). Antibiotics are drugs of natural or synthetic origin that have the capacity to kill or to inhibit the growth of micro-organisms included MAS. However, the use of antibiotics in the long term can cause negative impacts, among others, feared the occurrence of bacterial resistance in certain antibiotics. The results showed five of isolates were sensitive to antibiotics of chloramphenicol, gentamycin, oxytetracycline, cefradoxil and nalidixic acid but resistant to vancomycin colistin sulphate, rifampisin, cephalosporin and novobiocin.

    Meirawan, D.; Ana, A.; Saripudin, S.

    2018-02-01

    The current condition of VHS is still inadequate in quality, quantity and relevance. The purpose of this research is to analyse the development of VHS based on the development of regional potential by using principal component analysis (PCA) in Bandung, Indonesia. This study used descriptive qualitative data analysis using the principle of secondary data reduction component. The method used is Principal Component Analysis (PCA) analysis with Minitab Statistics Software tool. The results of this study indicate the value of the lowest requirement is a priority of the construction of development VHS with a program of majors in accordance with the development of regional potential. Based on the PCA score found that the main priority in the development of VHS in Bandung is in Saguling, which has the lowest PCA value of 416.92 in area 1, Cihampelas with the lowest PCA value in region 2 and Padalarang with the lowest PCA value.

    Full Text Available Chryseobacterium indologenes is a rare cause of infection in children. The organism causes infections mostly in hospitalised patients with severe underlying diseases. The choice of an effective drug for the treatment of infections due to C. indologenes is difficult as the organism has a limited spectrum of antimicrobial sensitivity. We present a case of nosocomial septicemia caused by C. indologenes in an infant with congenital heart disease who was successfully treated with trimethoprim sulfamethoxazole and also reviewed fourteen additional cases of C. indologenes infections reported in the English literature in this report.

    1994-07-01

    Mass storage is one of the key technology of next generation computer system. A huge amount of data is produced on a field of particle and nuclear physics. These data are raw data of experiments, analysis data, Monte Carlo simulations data, etc. We search a storage device for these data at the point of view of capacity, price, size, transfer speed, etc. We have selected a VHS-tape (12.7 mm-tape, helical scan) from many storage devices. Characteristics of the VHS-tape are as follows; capacity of 14.5 GB, size of 460 cm 3 , price of 1,000 yen (S-VHS tape for video use), and 1.996 MB/sec transfer speed at a sustained mode. Last year, we succeeded to operate the VHS-tape system on a workstation as a I/O device with read/write speed of 1.5 MB/sec. We have tested a VHS-tape system by connecting to the channel of the general purpose computer (Fujitsu M-780/10S) in our institute. We obtained a read and write speeds of 1.07 MB/sec and 1.72 MB/sec by FORTRAN test programs, respectively. Read speeds of an open reel tape and a 3480 type cassete tape by the same test programs are 1.13 MB/sec and 2.54 MB/sec, respectively. Speeds of write operation are 1.09 MB/sec and 2.54 MB/sec for the open reel and 3480 cassete tape, respectively. A start motion of the VHS-tape for read/write operations needs about 60 seconds.

    Full Text Available We present a 29-year-old healthy man who fell into an industrial auger, sustaining acrushed, open pelvic injury, multiple comminuted fractures of the right leg, and traumaticamputation of his left foot. Blood and wound cultures were positive for Aeromonasspp and vancomycin resistant Enterococcus. Treatment included cefepime, levofloxacin,daptomycin, and metronidazole. Aeromonas veronii is a Gram negative bacillus usuallyfound in fresh and brackish water in warm climates. It can cause severe skin andsoft tissue infections, typically after injured tissue is exposed to contaminated water.Aeromonas septicemia is uncommon and is usually associated with underlying diseases,such as malignancy, cirrhosis, diabetes, or immunosuppression. It rarely occurs in ahealthy host.

  1. Aeromonas caviae septicemia in immunocompetent gastrointestinal carriers

    M. Dwivedi

    Full Text Available Aeromonas caviae strains have been isolated from blood and stool cultures of three immunocompetent patients, residents of Northern India, who presented with community acquired septicemia without any recent history of diarrhea. Cell culture infectivity test performed on Hep-2 cells have shown substantial degree of invasiveness in the isolated strains. This case unleashes a possibility of asymptomatic gastrointestinal carriage of such strains of A. caviae in a very large population of India, as several areas of India have very high rates of Aeromonas induced acute diarrhea/gastroenteritis (up to 13%. It needs to be appraised further in India as well as other countries having high rates of Aeromonas induced acute diarrhea/gastroenteritis.

    Boo, N Y; Wong, Y H; Lim, V K

    1989-09-01

    Over a 12 months period, out of 25,411 livebirths, 155 neonates (6.1 per 1000 livebirths) had proven septicemia by blood culture. The mortality rate was 26.5%. Septicemia was more common among the very low birthweight and preterm neonates of gestation of 30 weeks or less. 45.8% of the septicemia occurred during the first 48 hours of life. Staphylococcus epidermidis was the most common causative organism. However, mortality was highest among neonates who acquired multiresistant nosocomial infection during the later part of neonatal life.

    Vibrio parahemolyticus is a halophilic marine vibrio commonly associated with outbreaks of acute gastroenteritis which also sometimes causes serious wound infection. It is an uncommon cause of septicemia. A few reports suggest that patients with chronic liver disease and leukemia are more susceptible. A case of liver cirrhosis with septicemia caused by this organism is discussed. The patient's condition rapidly deteriorated, and he died 12 hours after admission.

  7. The herpes simplex virus 2 virion-associated ribonuclease vhs interferes with stress granule formation.

    Finnen, Renée L; Hay, Thomas J M; Dauber, Bianca; Smiley, James R; Banfield, Bruce W

    2014-11-01

    In a previous study, it was observed that cells infected with herpes simplex virus 2 (HSV-2) failed to accumulate stress granules (SGs) in response to oxidative stress induced by arsenite treatment. As a follow-up to this observation, we demonstrate here that disruption of arsenite-induced SG formation by HSV-2 is mediated by a virion component. Through studies on SG formation in cells infected with HSV-2 strains carrying defective forms of UL41, the gene that encodes vhs, we identify vhs as a virion component required for this disruption. Cells infected with HSV-2 strains producing defective forms of vhs form SGs spontaneously late in infection. In addition to core SG components, these spontaneous SGs contain the viral immediate early protein ICP27 as well as the viral serine/threonine kinase Us3. As part of these studies, we reexamined the frameshift mutation known to reside within the UL41 gene of HSV-2 strain HG52. We demonstrate that this mutation is unstable and can rapidly revert to restore wild-type UL41 following low-multiplicity passaging. Identification of the involvement of virion-associated vhs in the disruption of SG formation will enable mechanistic studies on how HSV-2 is able to counteract antiviral stress responses early in infection. In addition, the ability of Us3 to localize to stress granules may indicate novel roles for this viral kinase in the regulation of translation. Eukaryotic cells respond to stress by rapidly shutting down protein synthesis and storing mRNAs in cytoplasmic stress granules (SGs). Stoppages in protein synthesis are problematic for all viruses as they rely on host cell machinery to synthesize viral proteins. Thus, many viruses target SGs for disruption or modification. Infection by herpes simplex virus 2 (HSV-2) was previously observed to disrupt SG formation induced by oxidative stress. In this follow-up study, we identify virion host shutoff protein (vhs) as a viral protein involved in this disruption. The

  10. [Neonatal septicemia in the G-DRG system].

    Mohrmann, M; Hentschel, R; Böhler, T; Dirschedl, P

    2006-12-01

    The introduction of Diagnosis Related Groups in Germany (G-DRG) has brought forward the obligation for physicians to take into account an intricate system of medical, economical and legal implementations. Mistakes in the process of encoding the principal diagnosis or procedures may have financial consequences. Problems to determine the correct ICD-code will be most prominent for diseases with poorly defined or even inconsistent diagnostic criteria as is the case for neonatal septicemia. We decided to evaluate whether the introduction of G-DRG resulted in a change of frequency of the diagnosis "neonatal septicemia". We analysed data derived from the quality assurance program "Neonatalerhebung" in the state of Baden-Württemberg during the years of 2001 through 2004, i. e., 2 years before and 2 years during the introduction of G-DRG. During this period an annual number of 12,316 up to 13,172 newborns were admitted to the participating hospitals. The mean number of diagnoses per patient increased from 2.2 to 3.8. The frequency of the diagnosis of septicemia remained constant. The percentage of newborns receiving antibiotic therapy did not change. The ratio of cases with "septicemia yes" over "antibiotics yes" did not change. Although it is difficult to determine the diagnosis of neonatal septicemia and in spite of the economic implications of this diagnosis, no change in the frequency of this diagnosis occurred during the introduction of DRG. Assuming that the participating hospitals used an identical database for the quality assurance program "Neonatalerhebung" and for accounting, we conclude that the DRG system is stable with respect to neonatal septicemia.

  13. Improving solubility and refolding efficiency of human V(H)s by a novel mutational approach.

    Tanha, Jamshid; Nguyen, Thanh-Dung; Ng, Andy; Ryan, Shannon; Ni, Feng; Mackenzie, Roger

    2006-11-01

    The antibody V(H) domains of camelids tend to be soluble and to resist aggregation, in contrast to human V(H) domains. For immunotherapy, attempts have therefore been made to improve the properties of human V(H)s by camelization of a small set of framework residues. Here, we have identified through sequence comparison of well-folded llama V(H) domains an alternative set of residues (not typically camelid) for mutation. Thus, the solubility and thermal refolding efficiency of a typical human V(H), derived from the human antibody BT32/A6, were improved by introduction of two mutations in framework region (FR) 1 and 4 to generate BT32/A6.L1. Three more mutations in FR3 of BT32/A6.L1 further improved the thermal refolding efficiency while retaining solubility and cooperative melting profiles. To demonstrate practical utility, BT32/A6.L1 was used to construct a phage display library from which were isolated human V(H)s with good antigen binding activity and solubility. The engineered human V(H) domains described here may be useful for immunotherapy, due to their expected low immunogenicity, and in applications involving transient high temperatures, due to their efficient refolding after thermal denaturation.

  15. Intracranial Hemorrhage

    2011-01-01

    Intracranial hemorrhage is a life-threatening condition, the outcome of which can be improved by intensive care. Intracranial hemorrhage may be spontaneous, precipitated by an underlying vascular malformation, induced by trauma, or related to therapeutic anticoagulation. The goals of critical care are to assess the proximate cause, minimize the risks of hemorrhage expansion through blood pressure control and correction of coagulopathy, and obliterate vascular lesions with a high risk of acute rebleeding. Simple bedside scales and interpretation of computed tomography scans assess the severity of neurological injury. Myocardial stunning and pulmonary edema related to neurological injury should be anticipated, and can usually be managed. Fever (often not from infection) is common and can be effectively treated, although therapeutic cooling has not been shown to improve outcomes after intracranial hemorrhage. Most functional and cognitive recovery takes place weeks to months after discharge; expected levels of functional independence (no disability, disability but independence with a device, dependence) may guide conversations with patient representatives. Goals of care impact mortality, with do-not-resuscitate status increasing the predicted mortality for any level of severity of intraparenchymal hemorrhage. Future directions include refining the use of bedside neuromonitoring (electroencephalogram, invasive monitors), novel approaches to reduce intracranial hemorrhage expansion, minimizing vasospasm, and refining the assessment of quality of life to guide rehabilitation and therapy.

  16. Amikacin treatment of Serratia septicemia in critically ill patients.

    Mosquera, J M; de Villota, E D; de la Serna, J L; Diez-Balda, V; Tomás, M I; Galdos, P; Rubio, J J

    1981-09-01

    Serratia marcescens septicemia represents a serious problem in high risk critical care patients. Treatment is difficult because Serratia is usually resistant to most antibiotics. Amikacin is at present the most effective antibiotic in vitro against gentamycin-resistant Serratia, although significant loss of activity may occur in vivo in the group of compromised patients, whose ultimate prognosis may depend eventually upon other associated conditions. In this Medical ICU, 15 patients with Serratia septicemia who were treated with in vitro effective antibiotics (14 were given amikacin) had a mortality of 60%, while 5 patients who received ineffective in vitro antibiotics had a mortality of 100%. In this ICU, 80% of the Serratia isolates were resistant to gentamycin, while only 2.8% were resistant to amikacin. Because amikacin-resistant strains of Serratia have already emerged, appropriate use of this antibiotic is essential in order not to promote the selection of amikacin-resistant strains.

  19. Purpura fulminans associated with Streptococcus pneumoniae septicemia in an asplenic pediatric patient.

    Konda, S; Zell, D; Milikowski, C; Alonso-Llamazares, J

    2013-09-01

    Purpura fulminans is a rapidly progressive syndrome of small-vessel thrombosis and hemorrhagic necrosis of the skin accompanied by disseminated intravascular coagulation. We describe a case of Streptococcus pneumoniae septicemia in an asplenic 5-year-old boy on oral tacrolimus, with a past medical history of multivisceral organ transplantation and subsequent development of purpura fulminans on his chest and distal extremities. The acute infectious form of purpura fulminans is usually caused by gram-negative bacteria. Cases secondary to gram-positive encapsulated bacteria usually occur when individuals are immuno-suppressed or have anatomic or functional asplenia. Our patient had both, which likely increased his susceptibility, and he responded well to antimicrobial therapy in addition to prophylactic coverage in the setting of his immunosuppression. We review the literature for similar cases due to S. pneumoniae in the pediatric population and discuss the etiology and treatment of purpura fulminans.

  20. Streptococcus bovis/S. equinus complex septicemia in a group of calves following intramuscular vaccination.

    Clarke, Lorelei L; Fathke, Robert L; Sanchez, Susan; Stanton, James B

    2016-07-01

    Organisms previously classified as Streptococcus bovis (i.e., the S. bovis/S. equinus complex) are common in cattle feces, but may also act as opportunistic pathogens. In the current work, Streptococcus infantarius subsp. coli, a member of this complex, was associated of a cluster of calves that died within hours of injection with a modified live viral vaccine. Within 12 h of vaccination of 46 calves at a cow/calf operation, 4 calves had died, 3 calves were ill, and 1 unvaccinated cow was dead. Autopsies were performed on the cow, 2 dead calves, and 1 affected surviving calf, which was euthanized ~24 h after vaccine administration. The animals had similar gross anatomic and microscopic lesions, including subcutaneous and intramuscular dark hemorrhage on the caudal neck, multiorgan ecchymosis and petechiation, and alveolitis to interstitial pneumonia. Gram-positive cocci were in the vasculature of the lung and skeletal muscle, and S. infantarius subsp. coli was cultured from tissues and from the vaccines used on affected animals, but not in vials used on unaffected animals. Together, these findings suggest death caused by streptococcal septicemia and toxemia as a result of contamination. © 2016 The Author(s).

  4. Characterization of Salmonella Typhimurium isolates associated with septicemia in swine

    Bergeron, Nadia; Corriveau, Jonathan; Letellier, Ann; Daigle, France; Quessy, Sylvain

    2010-01-01

    Salmonella Typhimurium is frequently isolated from pigs and may also cause enteric disease in humans. In this study, 33 isolates of S. Typhimurium associated with septicemia in swine (CS) were compared to 33 isolates recovered from healthy animals at slaughter (WCS). The isolates were characterized using phenotyping and genotyping methods. For each isolate, the phage type, antimicrobial resistance, and pulsed-field gel electrophoresis (PFGE) DNA profiles were determined. In addition, the protein profiles of each isolate grown in different conditions were studied by Coomassie Blue-stained sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot. Various phage types were identified. The phage type PT 104 represented 36.4% of all isolates from septicemic pigs. Resistance to as many as 12 antimicrobial agents, including some natural resistances, was found in isolates from CS and WCS. Many genetic profiles were identified among the PT 104 phage types. Although it was not possible to associate one particular protein with septicemic isolates, several highly immunogenic proteins, present in all virulent isolates and in most isolates from clinically healthy animals, were identified. These results indicated that strains associated with septicemia belong to various genetic lineages that can also be recovered from asymptomatic animals at the time of slaughter. PMID:20357952

  5. Can VHS Virus Bypass the Protective Immunity Induced by DNA Vaccination in Rainbow Trout?

For the in vitro approach, the virus collected from the last passage (passaged virus was as sensitive as the parental virus to serum neutralization, suggesting that the passaging did not promote the selection of virus populations able to bypass the neutralization by serum antibodies. Also, in the in vivo approach, where virus was passaged several times in vaccinated fish, no increased virulence nor increased persistence in vaccinated fish was observed in comparison with the parental virus. However, some of the vaccinated fish did get infected and could transmit the infection to naïve cohabitant fish. The results demonstrated that the DNA vaccine induced a robust protection, but also that the immunity was non-sterile. It is consequently important not to consider vaccinated fish as virus free in veterinary terms.

    This cross-sectional study was done to evaluate diagnostic efficacy of urine nested polymerase chain reaction (PCR) using broad-range 16SrDNA PCR-based amplification, followed by restriction analysis and sequencing in neonatal septicemia. The study included 50 babies; 48% had vaginal delivery, 46% were preterm, 20% had a history of prolonged rupture of membranes and 56% were low birth weight (≤2500 g). Clinical presentations were lethargy (96%), respiratory distress (80%) and bleeding diathesis (16%). Absolute neutrophil count value, negative predictive value and accuracy of nested PCR were 100, 60, 78.9, 100 and 84%, respectively, compared with blood culture. Nested PCR can detect most bacteria in single assay and identify unusual and unexpected causal agents. © The Author [2015]. Published by Oxford University Press. All rights reserved.

    The clinical and CT findings in 10 patients with primary pontine hemorrhage were reviewed. All patients were hypertensive. Pontine hemorrhage can be divided into 3 groups from the viewpoint of location of hematomas. These are the tegmentobasilar type, tegmental type and basilar type. The tegmentobasilar type produces characteristic clinical features for pontine hemorrhage and poor prognosis, otherwise, another two types produce atypical clinical features for pontine hemorrhage and good prognosis.

    Full Text Available Abstract: The VHS and CTR were assessed using computerized thoracic radiographs of ten clinically healthy tufted capuchin monkeys (five males and five females from the Wild Animal Screening Center in São Luís (Centro de Triagem de Animais Silvestres de São Luís-MA-CETAS. Radiographs were taken in laterolateral and dorsoventral projections to calculate the cardiothoracic ratio (VHS and vertebral heart size (CTR. The VHS showed mean values of 9.34±0.32v (males and 9.16±0.34v (females and there was no statistical difference between males and females (p>0.05. The CTR showed mean values of 0.55±0.04 (males and 0.52±0.03 (females and there was no statistical difference between the sexes (p>0.05. There was positive correlation between VHS and CTR (r=0.78. The thoracic and heart diameters showed mean values of 5.70±0.48cm and 2.16±0.40cm in the males, respectively. In the females they measured 5.32±0.39cm and 2.94±0.32cm. There was no statistical difference between the sexes. Our results show that the high correlation found between VHS and CTR permitted the verification with similar clinical precision between the two methods to estimate alterations in the heart silhouette by radiographic examination of tufted capuchin, making it an easy technique to apply that can be considered in the investigation of heart problems for this wild species.

    Full Text Available We report a term neonate with hypoxic ischemic encephalopathy who underwent a 72-hour therapeutic hypothermia. He developed unstable body temperature associated with coagulase negative staphylococcus septicemia 2 weeks later which was promptly treated with intravenous antibiotics and made a good recovery. PubMed (a service of the U.S. National Library of Medicine was searched for the terms “therapeutic hypothermia” and “septicemia,” with limits activated (humans, English, age 0–18 years. There were only 6 randomized controlled trials, 1 non-randomized controlled trial, 1 retrospective cohort, and 1 case-control trial, which showed no definite evidence of increased risk of septicemia or neutrophil dysfunction in infants following hypothermia therapy.

    2011-01-01

    Full Text Available Background: Bacterial infections remain an important cause of pediatric mortality and morbidity. It might be possible to reduce these factors by early diagnosis and proper management. Aim: The aim of the study was to analyze the bacteriological profiles with their antibiogram, and to register the risk factors for septicemia in neonates and infants. Setting and design: This observational cross-sectional study was conducted in a tertiary care teaching hospital at Gangtok, Sikkim, India, and included clinically suspected cases of septicemia in neonates and infants. Materials and Methods: Blood culture reports were studied in 363 cases of clinically suspected septicemia in neonates and infants, using the standard technique of Mackie and McCartney. The antibiotic sensitivity was performed by Kirby-Bauer′s disc diffusion method. Risk factors for sepsis in the children were registered. Results: Blood culture was positive in 22% of cases. Gram-negative septicemia was encountered in 61% of the culture-positive cases. Pseudomonas and Enterobacter species were the predominant pathogens amongst gram-negative organisms. Most gram-negative organisms were sensitive to Amikacin, Ciprofloxacin, and Co-trimoxazole. The most common gram-positive organism isolated was Staphylococcus aureus (97%. More than 70% of Staphylococci isolated were resistant to Penicillin, but were sensitive to Clindamycin (70% and Vancomycin (40%. The most important risk factors of septicemia in our study population were preterm birth (31%, followed by respiratory distress (5% and low birth weight (4%. Conclusion: As the cultures showed variable antibiogram with complicated patterns of resistance, culture and sensitivity test should be performed in all cases of septicemia.

    Full Text Available Neonatal septicemia is an important cause of morbidity and mortality. The present study was undertaken to determine the bacteriological profile and antimicrobial susceptibility pattern of prevalent pathogens isolated from the blood of septicemic neonates from Neonatal Intensive Care Unit (NICU. A total of 180 blood samples of septicemic neonates were studied bacteriologically. Antimicrobial susceptibility testing was done by the Kirby Bauer disc diffusion method in accordance to Clinical Laboratory Standards Institutes (CLSI guidelines. 26.6% (48 out of 180 cases of septicemia could be confirmed by blood culture. Of these, 66.7% cases were of early onset septicemia (EOS and 33.3% were of late onset septicemia (LOS. Klebsiella pneumoniae was the predominant pathogen (35.4% among the Gram-negative pathogens and Staphylococcus aureus (22.9% was the predominant Gram-positive pathogen. 28% of K. pneumoniae and E. coli isolates were extended spectrum beta-lactamase (ESBL producers. 18.1% of the Staphylococcus isolates were methicillin-resistant S. aureus (MRSA. Multi-drug-resistance pattern was observed with all the isolates. Ciprofloxacin and aminoglycosides were the most effective drugs against Gram-positive and Gram-negative isolates. This study highlights the predominance of Gram-negative organisms in causing neonatal sepsis and emergence of multi-drug-resistant strains in our set up.

    2012-01-01

    Previous studies of pediatric intracerebral hemorrhage have investigated isolated intraparenchymal hemorrhage. We investigated whether detailed assessment of intraventricular hemorrhage enhanced outcome prediction after intracerebral hemorrhage. We prospectively enrolled 46 children, full-term to 17 years, median age 2.7 years with spontaneous intraparenchymal hemorrhage and/or intraventricular hemorrhage. Outcome was assessed with the King’s Outcome Scale for Childhood Head Injury. Twenty-six (57%) had intraparenchymal hemorrhage, 10 (22%) had pure intraventricular hemorrhage, and 10 (22%) had both. There were 2 deaths, both with intraparenchymal hemorrhage + intraventricular hemorrhage volume ≥4% of total brain volume. Presence of intraventricular hemorrhage was not associated with poor outcome, but hydrocephalus showed a trend (p=0.09) toward poor outcome. In receiver operating characteristic curve analysis, combined intraparenchymal hemorrhage + intraventricular hemorrhage volume also showed a trend toward better outcome prediction than intraparenchymal hemorrhage volume alone. Although not an independent outcome predictor, future studies should assess intraventricular hemorrhage qualitatively and quantitatively. PMID:22068828

    2014-06-01

    Full Text Available Haemophilus influenzae (H. influenzae type B a non-motile, aerobic, gram negative cocobacillus is a commensal of upper respiratory tract. Genitourinary infection due to H. influenzae has been reported but bacteremia associated with such infection appears to be rare. We report a case of 19 years young primigravida with complaints of amenorrhea of 32 weeks and 5 days, pyrexia, abdominal pain and blood stained discharge per vaginum. H. influenzae type B was recovered from the genital tract as well as blood of the mother indicating maternal septicemia. Septicemia caused by H. influenzae type B in pregnant women following vaginal colonization and infection is rare. It has been reported in many parts of world over the years; to the best of our knowledge this is the first reported case from Nepal. H. influenzae should be considered as a potential maternal, fetal, and neonatal pathogen.

  10. Hemorrhagic brain metastases

    Takahashi, Motoichiro; Takekawa, S.D.; Suzuki, Kenzo

    1986-01-01

    Tumor hemorrhage on computed tomography (CT) was found in 14 patients with brain metastases (7 % of two hundred patients with brain metastases), from April 1979 to July 1983. Primary foci of these lesions were the lung (6 patients), breast (2), kidney (2), uterus (2), colon (1) and adrenal gland (1). ''Stroke'' syndrome was the initial presenting symptom in 3 patients; neurological focal sign or symptoms of increased intracranial pressure in the remaining patients. CT demonstrated peritumoral hemorrhage in all patients with solid mass, intratumoral hemorrhage in a few patients and also cerebral or ventricular hemorrhage, which was fatal complication, in 2 patients (colon and breast cancers). A cystic mass with fluid-blood level was noted in a patient with breast cancer. Several predisposing factors including chemotherapy, thrombocytopenia, radiotherapy or combination of these were recognized in 8 patients. Of these, chemotherapy was the most causative factor of tumor hemorrhage. Brain irradiation for hemorrhagic brain metastases was effective for prolongation of mean survival time of these patients as follows; 10 months in irradiated group, whereas 1.5 months in non-irradiated group.

  11. Imaging of Hemorrhagic Stroke.

    Hakimi, Ryan; Garg, Ankur

    2016-10-01

    Hemorrhagic stroke comprises approximately 15% to 20% of all strokes. This article provides readers with an understanding of the indications and significance of various neuroimaging techniques available for patients presenting with hemorrhagic strokes of distinct causes. The most common initial neuroimaging study is a noncontrast head CT, which allows for the identification of hemorrhage. Once an intracranial hemorrhage has been identified, the pattern of blood and the patient's medical history, neurologic examination, and laboratory studies lead the practitioner to pursue further neuroimaging studies to guide the medical, surgical, and interventional management. Given that hemorrhagic stroke constitutes a heterogeneous collection of diagnoses, the subsequent neuroimaging pathway necessary to better evaluate and care for these patients is variable based on the etiology.With an increasing incidence and prevalence of atrial fibrillation associated with the aging population and the introduction of three new direct factor Xa inhibitors and one direct thrombin inhibitor to complement vitamin K antagonists, oral anticoagulant use continues to increase. Patients on oral anticoagulants have a sevenfold to tenfold increased risk for intracerebral hemorrhage (ICH). Furthermore, patients who have an ICH associated with oral anticoagulant use have a higher mortality rate than those with primary ICH. Despite the reduced incidence of hypertension-related ICH over the past decade, it is expected that the incidence of ICH will continue to increase. Neuroimaging studies are integral to the identification of hemorrhagic stroke, determination of the underlying etiology, prevention of hematoma expansion, treatment of acute complications, and treatment of the underlying etiology, if indicated. Neuroimaging is essential for prognostication and thus directly impacts patient care.

    Full Text Available Radiographic examination of the toracic cavity is an usefull noninvasive method for assessment, monitoring the progress of heart disease, suggesting prognosis and guiding the treatment. The aim of this study was to evaluate the cardiac silhouette of young and adults coatis and evaluate its relationship to the number of thoracic vertebrae (VHS, the method proposed by Buchanam and Buchele (1995 for small animals. We evaluated a group of 20 coatis, divided by age: I (GI and 8 animals aged between 4 and 5 months and group II (GII with 12 animals over 12 months old. Based in chest radiographs and VD laterolateral right projections for determining the major axis (L and short axis (Y being the sum of L and S is the value obtained by ESR, the relative depth/width (D / L chest were obtained and the results determined the type of conformation of the thorax, which results greater than 1.25 cm denote chest type deep, 0.75 to 1.25 cm chest intermediate and inferior results will 0.75cm wide chest. It was observed that the heart is alocated between the fourth and seventh pair of ribs, VHS average coatis healthy adults was 9.36 ± 0.75 and 8.06 ± 0 youth, 595 units thoracic vertebrae and the predominant conformation found was of intermediate type when compared to dogs. The mean values in this study serve as a basis for interpretation of the VHS type, however, a larger number may be required animals to determine the physiological limits of the cardiac silhouette in coati.

    Seppaenen, Seppo K.; Leppaenen, Martti J.; Pimenoff, Georg; Seppaenen, Janne M.

    1997-01-01

    Purpose. To evaluate the efficacy of embolotherapy using microcatheters in patients with hemorrhage from various locations. Methods. Among 29 patients there were 13 with severe epistaxis, 7 with gastrointestinal bleeding, 4 with hemorrhage in the kidney, 4 with bleeding in pelvic organs and 1 with bleeding in the shoulder region. In all cases, a Tracker-18 or Tracker-10 microcatheter was advanced coaxially through a 4.1 Fr guiding catheter in order to reach the bleeding site as distally as possible. Polyvinyl alcohol microparticles and/or platinum microcoils were used as embolic material. Results. The bleeding was stopped in 90% (26 of 29) of cases. In 66% of cases the treatment was curative, in 7% preoperative, and in 17% palliative. There were 3 clinical failures. Conclusion. Microcatheter embolization is an effective and safe means of managing different kinds of hemorrhage of various causes from a variety of sites

  14. Subconjonctival hemorrhage secondary to use of diclofenac and paracetamol for suicidal attempt

    Esra Yıldızhan

    2011-03-01

    Full Text Available Although paracetamol and diclofenac sodium are most commonly used drugs and considered as safe, they are also frequently become a current issue with complications in therapeutic doses or overdose situations. Both drugs can cause bleeding disorders as a result of platelet dysfunction and can be presented as an atypical clinical situation such as subconjunctival hemorrhage. In these presented cases, the subconjunctival hemorrhage seen after ingestion of paracetamol and diclofenac sodium in toxic doses for the purpose of suicide, is considered as related with the bleeding disorder that is associated with drug side effect. For these patients who do not have any known co-morbidities, the reasons that can cause subconjunctival hemorrhage other than drugs such as trauma, infections, thrombocytopenia, malignant blood disorders, septicemia, hypertension, severe cough are excluded. Although hepatic and renal toxicities are commonly known side effects that are related with high doses of these drugs, in our cases there were not any impairment of hepatic or renal function tests other than compensated metabolic acidosis. In this report, the relationship of parasetamol and diclofenac sodium with bleeding disorders is discussed over two cases which presented as subconjunctival hemorrhage.

Virus evolution: Recent studies indicate that only a few amino acid changes in the structural proteins of VHSV can change the virulence patterns significantly, thereby coming closer to assessing the risk of none to low virulent viruses becoming high...... virulent. Virulence factors both depend on the ability of VHSV to enter a cell and on the speed and efficiencyof virus replication in the cells. Apparently the viral nucleocapsid protein plays a very important role for the later and seems to be the target for determination of a virulence marker....

  20. Cutaneous gallium uptake in patients with AIDS with mycobacterium avium-intracellulare septicemia

    Allwright, S.J.; Chapman, P.R.; Antico, V.F.; Gruenewald, S.M.

    1988-01-01

    Gallium imaging is increasingly being used for the early detection of complications in patients with AIDS. A 26-year-old homosexual man who was HIV antibody positive underwent gallium imaging for investigation of possible Pneumocystis carinii pneumonia. Widespread cutaneous focal uptake was seen, which was subsequently shown to be due to mycobacterium avium-intracellulare (MAI) septicemia. This case demonstrates the importance of whole body imaging rather than imaging target areas only, the utility of gallium imaging in aiding the early detection of clinically unsuspected disease, and shows a new pattern of gallium uptake in disseminated MAI infection

    Full Text Available A 40-year-old farmer from the district of North Karnataka who had received treatment for high fever of 8 days duration was admitted with fever, dyspnea, and poor general condition. Ultrasonography and echocardiogram revealed multiple splenic abscesses, vegetation on atrioventricular valve, aortic regurgitation (Grade I–II, and mitral valve regurgitation (Grade II–III, respectively. Brucella melitensis was detected in blood culture, and high titers of IgM and IgG anti-Brucella antibodies were observed in Brucella specific serological tests. The patient developed fulminant septicemia and succumbed due to multi-organ failure.

    A 71-year old patient suffering from untreated non-insulin-dependent diabetes presented anti-inflammatory drug-resistant lumbalgia with referred inguinal pain either on the right or left side, corresponding to the first signs of septicemia due to staphylococcus aureus, with urinary onset. Despite specific antibiotic treatment, pulmonary, cardiac and neurological complications followed. Simultaneous investigations by MRI and bone scintigraphy performed in the remitting patient showed multiple septic metastatic localization in the soft tissues and bones. It was hence necessary to pursue the antibiotic therapy to avoid relapses. (author)

    Acute gastrointestinal hemorrhage is a common problem that requires prompt recognition and management to prevent serious morbidity and mortality. Management goals are stabilization of the patient with vigorous fluid resuscitation followed by investigation and definitive treatment of the bleeding source. Endoscopy is often the initial diagnostic test and allows therapeutic measures to be performed at the same time.

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

  5. Hemorrhage and vascular abnormalities

    Bradley, W.G.

    1990-01-01

    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, T 1 - or T 2 -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

  7. MR of acute subarachnoid hemorrhage

    Spickler, E.; Lufkin, R.; Frazee, J.; Lylyk, P.; Vinuela, F.; Bentson, J.; Dion, J.

    1987-01-01

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

  8. Various phases of intracerebral hemorrhage

    Kino, Masao; Anno, Izumi; Yano, Yuhiko; Anno, Yasuro.

    1980-01-01

    Cases of intracerebral hemorrhage except typical putamen thalamic hemorrhage were reported. It is not difficult to diagnose typical attacks of cerebral apoplexy in patients older than 40 years with hypertension by CT. When the condition of the onset is not typical, cerebral infarction must be considered. Though conservative treatment is performed for severe cerebral hemorrhage and cerbral infarction, there is no specific medicine curing these diseases completely. On the contrary, the risk that the administration of fibrinolysis activators and STA-MCA anastomosis may induce cerebral hemorrhage is stressed. Not a few patients with cerebral apoplexy accompanied by small hemorrhagic focuses have been found, especially since CT was used widely. However, treatment for this disease has many inconsistencies. From above-mentioned facts, we recognize excellent roles of CT in an application of surgery for cerebral hemorrhage of early stage, and we, general radiologists, are under an obligation to advise most adequate theraphy for each patient.

    2017-06-01

    Full Text Available Background Septicemia is a life-threatening condition particularly among pediatric population. Early initiating a proper empiric antimicrobial treatment prior to definite isolation of the pathogen through blood culture has pivotal role in reducing further mortality and morbidity. The aim of this study was to evaluate the epidemiological properties of a distinct Iranian population by patients’ age and gender throughout the year. Materials and Methods As a retrospective study between March 2013 and March 2017, all consecutive patients referred to the Hazrat Masumeh hospital of Qom-Iran with suspicious of septicemia were reviewed. Patients with prior history of antibiotic consumption as well as patients over 6 years of age were excluded; incomplete hospital records were also excluded from further evaluations. Prespecified data-extraction forms were used to collect data including characteristics of patients and the results of antibiogram. Results Total of 378 patients were enrolled in this study and 200 of them were boys (52.91%. Escherichia coli (11.6% and Klebsiella (9.5% were the most common isolated pathogens (Gram-negative after coagulase-negatives. Escherichia coli, Citrobacter (Gram-negative, and Staph. Aureus (Gram-positive were the most common pathogens among age group of 0-1 year. Winter had the greatest outbreak of bacteremia (29.1% and the autumn had the least incidence (21.4%. The least and the most antimicrobial resistance were associated with Imipenem (1.8% and Ampicillin (78.78%, respectively. Conclusion Escherichia coliand Klebsiella were the most common isolated bacteria in patients suspected to bacteremia in our region. Imipenem and Ampicillin had the least and the most antimicrobial resistance in our population, respectively.

    1983-01-01

    Computed tomography (CT) is the most accurate and reliable method for the diagnosis of intracerebral and intraventricular hemorrhage. The precise anatomic extent of the nematoma, associated cerebral edema, ventricular deformity and displacement, and hydrocephalus are all readily assessed. Aside from head trauma, the principal cause of intracerebral hematoma is hypertensive vascular disease. Although hematomas from various causes may present similar CT appearances frequently the correct etiology may be suggested by consideration of patient's age, clinical history, and the location of the hematoma. The analytical study was performed in 180 cases of intracerebral hemorrhages by CT from October 1981 to January 1983. The results were as follows; 1. The most prevalent age group was 6th decade (37.2%). Male was prevalent to female at the ration of 1.6 to 1. 2. The most common symptom and sign was mental disturbance (48.7%), motor weakness (23%), headache (10.6%), nausea and vomiting (9.8%). 3. The causes of hemorrhage were hypertension (53.9%), head trauma (30.6%), aneurysm (6.1%) and A-V malformation (7.2%). 4. The frequent locations of hemorrhage were basal ganglia and thalamus (40.4%), lobes (35%), ventricles (21.8%). 5. The distribution of hemorrhage was intracerebral hemorrhage (65.6%), intracerebral and intraventricular hemorrhage (30.3%), intraventricular hemorrhage (4.4%).

    1990-01-01

    Thirty patients with temporal hematomas were analyzed. Four with frontal extension survived. Of 6 with ganglionic extension, three had residual deficit. Of 8 with parietal extension, 4 had delayed deterioration and died, two patients recovered, and two with peritumoral hemorrhage due to glioblastoma multiforme died. Five patients with posterior temporal hematomas recovered. In 7 patients with basal-inferior temporal hematomas, angiography showed aneurysms in 3 cases, angiomas in 2 cases and no vascular lesion in 2 cases. Of 23 cases with negative angiography and no systemic cause for temporal hematoma, 12 patients were hypertensive and 11 were normotensive. Ten hypertensive patients without evidence of chronic vascular disease had the largest hematomas, extending into the parietal or ganglionic regions. Seven of these patients died; 3 had residual deficit. Eleven normotensive and two hypertensive patients with evidence of chronic vascular change had smaller hematomas. They survived with good functional recovery. (orig.)

  1. Detection of 400-year-old Yersinia pestis DNA in human dental pulp: An approach to the diagnosis of ancient septicemia

    Drancourt, Michel; Aboudharam, Gérard; Signoli, Michel; Dutour, Olivier; Raoult, Didier

    1998-01-01

    Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections such as plague remains hypothetical. The durability of dental pulp, together with its natural sterility, makes it a suitable material on...

  2. Intracerebral hemorrhage in brain tumors

    Fujita, Katsuzo; Matsumoto, Satoshi

    1980-01-01

    A series of 16 cases of intracerebral hemorrhage associated with brain tumors are described. The literature is reviewed and the incidence of these cases is reported to be low, but we had clinically encountered these cases more commonly than reported, since CT was introduced to the neurosurgical field as a diagnostic aid. The presenting symptoms were those of spontaneous intracerebral hemorrhage or brain tumor. The intracerebral hemorrhage associated with brain tumor may mask the cause of bleeding and confuse the diagnosis. The majority of the tumor causing the intracerebral hemorrhage are highly malignant as glioblastoma or metastatic brain tumor, but there are some benign tumors such as pituitary adenoma, hemangioblastoma, benign astrocytoma and meningioma, which would have good survival rates if discovered early. The mechanisms of massive hemorrhage with brain tumor are not clear. From pathological findings of our cases and other reports, the mechanism seems to be due to the vascular endothelial proliferation with subsequent obliteration of the lumen of the vessel. Thin walled, poorly formed vessels in tumor may also become distorted with growth of the tumor and these may easily rupture and bleed. Necrosis with subsequent loss of vessel support may be a factor in production of hemorrhage. Radiation therapy may be a predisposing factor. Children are rarely involved in these cases. The prognosis in the majority of cases would seen to be poor, since the majority of the tumor are highly malignant and most such patients are seen by the neurosurgeon some time after the hemorrhage has accomplished its fatal mischief.

    Ban, Sadahiko; Ogata, Masahiro; Yamamoto, Toyoshiro; Nakao, Satoshi; Mizue, Hidenari; Kobayashi, Yutaka.

    1982-01-01

    1. We have reviewed 34 cases of neonatal intracranial hemorrhages (perinatal onset, 23 mature and 11 premature infants) experienced in 10-year period from 1971 to 1980, with special reference to gestational age, birth weight, type of delivery, presence or absence of asphyxia, symptoms and cause of death. 2. Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages. (author)

  4. Hydrocephalus secondary to subarachnoid hemorrhage

    Koga, Nobunori; Nakamura, Saburo; Kushi, Hidehiko; Yamamoto, Takamitsu; Tsubokawa, Takashi; Moriyasu, Nobuo

    1982-01-01

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

    2000-01-01

    Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

  8. Fatal Vibrio parahemolyticus septicemia in a patient with cirrhosis. A case report and review of the literature.

    Hally, R J; Rubin, R A; Fraimow, H S; Hoffman-Terry, M L

    1995-06-01

    Vibrio parahemolyticus has been well documented to cause outbreaks of infectious diarrhea, usually related to poor food handling; only rarely has it been reported to cause fetal septicemia. In contrast, Vibrio vulnificus is a well-known cause of septicemia, especially in patients with cirrhosis. A 31-year-old woman with cirrhosis who developed fatal V. parahemolyticus sepsis after ingesting raw seafood is described. We review the clinical syndromes associated with sepsis caused by these two organisms. Leg pain and bullous skin lesions may be a clue to the diagnosis. Febrile patients with cirrhosis should be questioned regarding recent seafood ingestion, and appropriate antibiotics chosen if this history is obtained. Physicians should inform patients at risk to avoid raw seafood in an attempt to prevent this potentially lethal syndrome.

  9. Imaging features of diffuse pulmonary hemorrhage

    Schmit, M.; Vogel, W.; Horger, M.

    2006-01-01

    There are diverse etiologies of diffuse pulmonary hemorrhage, so specific diagnosis may be difficult. Conventional radiography tends to be misleading as hemoptysis may lacking in patients with hemorrhagic anemia. Diffuse pulmonary hemorrhage should be differentiated from focal pulmonary hemorrhage resulting from chronic bronchitis, bronchiectasis, active infection (tuberculosis) neoplasia, trauma, or embolism.

    A method is described for inhibiting the onset of acute radiation syndrome caused by the exposure of warm-blooded animals to a whole body dose of at least 100 rads of x-radiation. Also described is a method for inhibiting the onset of septicemia. The methods comprise administering to a warm-blooded animal an effective amount of a pharmaceutical preparation containing refined detoxified endotoxin in combination with a pharmaceutically acceptable carrier.

    Full Text Available Acute hemorrhagic edema of infancy is an uncommon benign cutaneous vasculitis. Despite its worrisome presentation, it carries good prognosis with rarely reported systemic involvement. Management of these cases has been an area of debate with majority of physicians adopting conservative modalities. We report a case that presented with classic triad of rash, low grade fever, and peripheral edema along with two rarely reported manifestations in literature: hemorrhagic lacrimation and epistaxis.

  13. Massive postpartum right renal hemorrhage.

    Kiracofe, H L; Peterson, N

    1975-06-01

    All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

  14. [Dermohypodermitis and gut translocation Escherichia coli septicemia in a newborn infant].

    The burden of neonatal bacterial infections continues. They remain a significant cause of death and morbidity, despite recommendations for prevention. The epidemiology of these infections has changed. Currently the two most causative pathogens for early-onset neonatal sepsis and for late-onset sepsis in term infants are Group B streptococci (GBS) and Escherichia coli. E. coli's role is increasingly important since the widespread use of intrapartum antibiotic prophylaxis. In late-onset infections, one of the suggested pathophysiological mechanisms is microbial translocation in the gut secondary to digestive colonization, particularly when E. coli is isolated in blood cultures. This can occur either before or after birth. Bacterial sepsis can be associated with various non-specific peripheral manifestations involving skin and soft tissues. We report the case of a full-term, 26-day-old newborn admitted to the hospital for fever. She presented with dermohypodermitis of the left trunk and was diagnosed with E. coli septicemia. She was discharged in good condition after appropriate intravenous antibiotic therapy. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    vaccine or the synthetic double-stranded RNA, poly LC. In both species there was a rapid response to poly LC detectable from day 1, reaching maximum from days 3 to 9 and decreasing to background level by day 12. The peak level and return to background was reached slightly later in salmon. In both species...... the response to the VHS/DNA vaccine was slower to begin, not being detectable on days 1 and 3, but elevated levels were found on day 6. However, in the salmon part, the peak level was on day 6 and the signal disappeared by day 12, while in the rainbow trout, the response peaked at day 12 and lasted until day......The duration of the Mx mRNA response to an intramuscular injection of the viral haemorrhagic septicaemia virus (VHSV) glycoprotein (G) gene DNA vaccine as well as to the control plasmid was determined in rainbow trout at 14 degreesC over a period of 11 weeks. The Mx response was detectable on day 7...

    1988-01-01

    In the past six years, we have had experience with 40 patients with hypertensive thalamic hemorrhages, as verified by CT scan at our hospital within 24 hours. These patients were classified into the following three groups according to the location of the bleeding point and the size of the hematoma: (1) anteromedial (4 cases), (2) posterolateral (16 cases), and (3) massive (20 cases). The (1) and (2) hematomas were small (less than 3 cm in diameter), while those in (3) were large (more than 3 cm in diameter). Twenty cases (50% of all the thalamic hematomas) were small hematomas. The characteristic clinical symptoms of the anteromedial type were a mild disturbance of consciousness and thalamic dementia, while those of the posterolateral type were motor and sensory disturbance, and thalamic aphasia, respectively. Twenty cases (50%) were large hematomas. The clinical symptoms of these cases were mainly consciousness disturbance; 7 of them expired. Based on this experience, it may be considered that the patients whose hematoma size was larger than 3 cm had a poor prognosis and that the patients with the posterolateral type had a poor functional diagnosis.

  17. MRI of intracranial hemorrhage

    Inoue, Yuichi; Takemoto, Kazumasa; Hashimoto, Hiromi

    1986-01-01

    Magnetic resonance (MR) images of 23 patients with putaminal or thalamic hematomas were reviewed. Inversion recovery (IR, TR; 2100 - 2500 msec, TI; 600 msec) and long spin echo (SE, TR; 1800 - 2500 msec, TE; 120 msec) images were obtained with a 0.5T MR scanner. Hematomas within 3 hours after hemorrhage were isointense to the gray matter on both IR and long SE images. Two day-old hematomas were hyperintense in part of it on IR images and hypointense on long SE images. In acute hematomas, there was a marked hyperintense crescent area around hematomas on long SE images which marked hypointense on IR images. Hematomas in the resolving stage had peripheral hyperintensity on IR images and then on long SE images. This hyperintensity filled into the center of hematomas with time. In the resolving stage linear hypointensity was recognized at immedeately adjacent to the hematoma on long SE images. In the chronic stage, hematomas were hypointense on both IR and long SE images. In a few cases, the central portion of hematomas demonstrated hyperintensity on long SE images which indicated the presence of fluid in the old hematoma cavity. (author)

  18. Liver repair and hemorrhage control by using laser soldering of liquid albumin in a porcine model.

    Wadia, Y; Xie, H; Kajitani, M

    2000-01-01

    We evaluated laser soldering by using liquid albumin for welding liver injuries. Major liver trauma has a high mortality because of immediate exsanguination and a delayed morbidity from septicemia, peritonitis, biliary fistulae, and delayed secondary hemorrhage. Eight laceration (6 x 2 cm) and eight nonanatomic resection injuries (raw surface, 6 x 2 cm) were repaired. An 805-nm laser was used to weld 50% liquid albumin-indocyanine green solder to the liver surface, reinforcing it with a free autologous omental scaffold. The animals were heparinized and hepatic inflow occlusion was used for vascular control. All 16 soldering repairs were evaluated at 3 hours. All 16 laser mediated liver repairs had minimal blood loss as compared with the suture controls. No dehiscence, hemorrhage, or bile leakage was seen in any of the laser repairs after 3 hours. Laser fusion repair of the liver is a reliable technique to gain hemostasis on the raw surface as well as weld lacerations. Copyright 2000 Wiley-Liss, Inc.

    The purpose of this study was to evaluate laser soldering using liquid albumin for welding liver lacerations and sealing raw surfaces created by segmental resection of a lobe. Major liver trauma has a high mortality due to immediate exsanguination and a delayed morbidity and mortality from septicemia, peritonitis, biliary fistulae and delayed secondary hemorrhage. Eight laceration injuries (6 cm long X 2 cm deep) and eight non-anatomical resection injuries (raw surface 6 cm X 2 cm) were repaired. An 805 nm laser was used to weld 53% liquid albumin-ICG solder to the liver surface, reinforcing it with a free autologous omental scaffold. The animals were heparinized to simulate coagulation failure and hepatic inflow occlusion was used for vascular control. For both laceration and resection injuries, eight soldering repairs each were evaluated at three hours. A single suture repair of each type was evaluated at three hours. All 16 laser mediated liver repairs were accompanied by minimal blood loss as compared to the suture controls. No dehiscence, hemorrhage or bile leakage was seen in any of the laser repairs after three hours. In conclusion laser fusion repair of the liver is a quick and reliable technique to gain hemostasis on the cut surface as well as weld lacerations.

  20. Hypertensive cerebellar hemorrhage and cerebellar hemorrhage caused by cryptic angioma

    Yoshida, Shinichi; Sano, Keiji; Kwak, Suyong; Saito, Isamu.

    1981-01-01

    A series of 44 patients with hypertensive cerebellar hemorrhage and nine patients with cerebellar hemorrhage caused by small angiomas is described. Hypertensive hemorrhage occurred most frequently in the patients in their seventies, whereas the onset of angioma-caused hemorrhage was often seen below the age of 40. Clinical syndromes of cerebellar hemorrhages can be categorized into three basic types: the vertigo syndrome, cerebellar dysfunction syndrome and brain stem compression syndrome. Patients with small (>= 2 cm in diameter in CT scans) and medium-sized (2 cm = 3 cm) hematomas deteriorated into unresponsive conditions and developed signs of brain stem compression. Surgical mortality was 32% in the hypertensive group, while it was 0% in the angioma group. Mortality as well as morbidity in both groups was strongly influenced by the preoperative status of consciousness. Our results suggest that substantial improvement could be obtained in the overall outcome of this disease by emergency craniectomy and removal of hematomas in all patients with large hematomas regardless of the levels of consciousness and regardless of the causes of bleeding. Furthermore, when clinical information and CT findings are suggestive of a ''cryptic'' angioma as the causative lesion, posterior fossa surgery may be indicated to extirpate the lesion, even if the hematoma is small.

  1. Aneurysmal Subarachnoid Hemorrhage

    2015-01-01

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

  2. Thalamic hemorrhage following carotid angioplasty and stenting

    Friedman, Jonathan A.; Kallmes, David F.; Wijdicks, Eelco F.M.

    2004-01-01

    Carotid angioplasty and stenting (CAS) has emerged as an alternative treatment of carotid stenosis for patients poorly suited for endarterectomy. Intracerebral hemorrhage following carotid revascularization is rare and thought to be related to hyperperfusion injury in most cases. Early experience suggests an increased incidence of hemorrhage following CAS as compared to endarterectomy. We describe a patient who suffered a thalamic hemorrhage following CAS. Because this hemorrhage occurred in a vascular territory unlikely to have been supplied by the treated artery, this case suggests that the mechanism of intracerebral hemorrhage following CAS may in some cases be different from the hyperperfusion hemorrhage classically described following endarterectomy.

    Devrieseasis caused by Devriesea agamarum is a highly prevalent disease in captive desert lizards, resulting in severe dermatitis and in some cases mass mortality. In this study, we assessed the contribution of autovaccination to devrieseasis control by evaluating the capacity of 5 different formalin-inactivated D. agamarum vaccines to induce a humoral immune response in bearded dragons (Pogona vitticeps). Each vaccine contained one of the following adjuvants: CpG, incomplete Freund's, Ribi, aluminium hydroxide, or curdlan. Lizards were administrated one of the vaccines through subcutaneous injection and booster vaccination was given 3 weeks after primo-vaccination. An indirect ELISA was developed and used to monitor lizard serological responses. Localized adverse effects following subcutaneous immunization were observed in all but the Ribi adjuvanted vaccine group. Following homologous experimental challenge, the incomplete Freund's as well as the Ribi vaccine were observed to confer protection in bearded dragons against the development of D. agamarum associated septicemia but not against dermatitis. Subsequently, two-dimensional gelelectrophoresis followed by immunoblotting and mass spectrometry was conducted with serum obtained from 3 lizards that showed seroconversion after immunisation with the Ribi vaccine. Fructose-bisphosphate aldolase and aldo-keto reductase of D. agamarum reacted with serum from the latter lizards. Based on the demonstrated seroconversion and partial protection against D. agamarum associated disease following the use of formalin-inactivated vaccines as well as the identification of target antigens in Ribi vaccinated bearded dragons, this study provides promising information towards the development of a vaccination strategy to control devrieseasis in captive lizard collections.

    2017-09-01

    The epidemiological features and financial losses due to Haemorrhagic Septicemia (HS) in bovines were studied in Karnataka state using the primary data collected from 133 clinically diagnosed HS affected farms. The various losses due to HS and the Benefit- Cost of the vaccination programme in cattle and water buffaloes were studied using mathematical models. The number of HS outbreaks were higher during the year 2002 and peaked during 2005 and thereafter declined due to targeted vaccination against HS. The morbidity and mortality risks were lower in large farms than medium and small farms, and lower in indigenous cattle compared to high yielding crossbred cattle and water buffaloes. The disease occurrence was more in in-milk animals causing serious economic loss to the farmers. Most outbreaks were observed during monsoon season, though the disease was prevalent throughout the year. The mean milk loss per animal was $2, $11 and $50 in indigenous cattle, water buffaloes and crossbred cattle, respectively. In the case of draught animals, the average effective draught power was unavailable for 1.2days/outbreak resulting in a loss of $5 per affected oxen. The treatment and extra labor expenses incurred per animal were $24 and $7, respectively. The average loss per animal due to mortality loss was $275, $284 and $415 in case of indigenous cattle, water buffaloes and crossbred cattle, respectively. The projected loss for the state of Karnataka were $23.89, $17.92 and $11.95 million under high, medium and low HS incidence scenarios, respectively. The Benefit Cost Analysis (BCA) of the vaccination against HS has been estimated at 5.97:1, 4.48:1 and 2.98:1 under high, medium and low incidence scenarios, respectively. The results highlight the important epidemiological features and financial losses to the affected households and the state of Karnataka. Copyright © 2017 Elsevier B.V. All rights reserved.

  6. Obstetric hemorrhage: A global review.

    Goffman, Dena; Nathan, Lisa; Chazotte, Cynthia

    2016-03-01

    Postpartum hemorrhage remains the number one cause of maternal death globally despite the fact that it is largely a preventable and most often a treatable condition. While the global problem is appreciated, some may not realize that in the United States postpartum hemorrhage is a leading cause of mortality and unfortunately, the incidence is on the rise. In New York, obstetric hemorrhage is the second leading cause of maternal mortality in the state. National data suggests that hemorrhage is disproportionally overrepresented as a contributor to severe maternal morbidity and we suspect as we explore further this will be true in New York State as well. Given the persistent and significant contribution to maternal mortality, it may be useful to analyze the persistence of this largely preventable cause of death within the framework of the historic "Three Delays" model of maternal mortality. The ongoing national and statewide problem with postpartum hemorrhage will be reviewed in this context of delays in an effort to inform potential solutions. Copyright © 2016 Elsevier Inc.

  7. Sequence variation of the glycoprotein gene identifies three distinct lineages within field isolates of viral hemorrhagic septicemia virus, a fish rhabdovirus

    Benmansour, A.; Bascuro, B.; Monnier, A.F.; Vende, P.; Winton, J.R.; de Kinkelin, P.

    1997-01-01

    To evaluate the genetic diversity of viral haemorrhagic septicaemia virus (VHSV), the sequence of the glycoprotein genes (G) of 11 North American and European isolates were determined. Comparison with the G protein of representative members of the family Rhabdoviridae suggested that VHSV was a different virus species from infectious haemorrhagic necrosis virus (IHNV) and Hirame rhabdovirus (HIRRV). At a higher taxonomic level, VHSV, IHNV and HIRRV formed a group which was genetically closest to the genus Lyssavirus. Compared with each other, the G genes of VHSV displayed a dissimilar overall genetic diversity which correlated with differences in geographical origin. The multiple sequence alignment of the complete G protein, showed that the divergent positions were not uniformly distributed along the sequence. A central region (amino acid position 245-300) accumulated substitutions and appeared to be highly variable. The genetic heterogeneity within a single isolate was high, with an apparent internal mutation frequency of 1.2 x 10(-3) per nucleotide site, attesting the quasispecies nature of the viral population. The phylogeny separated VHSV strains according to the major geographical area of isolation: genotype I for continental Europe, genotype II for the British Isles, and genotype III for North America. Isolates from continental Europe exhibited the highest genetic variability, with sub-groups correlated partially with the serological classification. Neither neutralizing polyclonal sera, nor monoclonal antibodies, were able to discriminate between the genotypes. The overall structure of the phylogenetic tree suggests that VHSV genetic diversity and evolution fit within the model of random change and positive selection operating on quasispecies.

    Bian Jieyong; Wang Zhong; Zhou Dai

    2000-01-01

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

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

  11. Cerebral hemorrhage caused by amyloid angiopathy

    Hanyu, Haruo; Tomonaga, Masanori; Yoshimura, Masahiro; Yamanouchi, Hiroshi; Shimada, Hiroyuki.

    1985-01-01

    Cerebral hemorrhage caused by amyloid angiopathy was studied clinicopathologically, with special attention given to the CT images. Cerebral hemorrhage caused by amyloid angiopathy is characterized, by a lobar-type hemorrhage involving the cortex, with direct extension into the subarachnoid space. Multiple hemorrhages are frequent, and cortical infarctions are present as complications in elderly patients without risk factors. CT scans taken in 5 cases demonstrated lobar hemorrhages in superficial locations, frequently in multiple sites or recurrently, with surrounding edema and mass effect. A subarachnoid extension of the hemorrhage through the superficial cortex, proven pathologically in all cases, was noted by CT in 4 of the 5 cases. However, cortical infarction was not detected by CT in any case. Therefore, CT is of value in the diagnosis of cerebral hemorrhage due to amyloid angiopathy based on distinctive findings such as a lobar hemorrhage in superficial regions, with extension into the subarachnoid space, frequently in multiple sites or recurrently.

    The effect of approximately 25% or 35% blood loss (b.l.) on volume, pressure, and protein concentration of pleural liquid has been determined in anesthetized rabbits in lateral or supine posture. Volume and pressure of pleural liquid did not change with 25% b.l. 30 and 60 min after beginning of hemorrhage, and with 35% b.l. at 30 min (bleeding time approximately 10 and 12 min, respectively). With 35% b.l. protein concentration of pleural liquid was 85% greater (PPleural liquid seems protected against derangements from hemorrhage up to 25% b.l. for periods shorter than 1 h.

  15. Eleven cases of neonatal intracranial hemorrhage

    Matsuda, Tadashi; Asao, Toyohiko; Shibata, Takeo

    1981-01-01

    Eleven cases of neonatal intracranial hemorrhage were diagnosed and followed up by CT scanning. By CT, hemorrhagic lesions were shown as high density areas in an acute stage and imaged as low density areas after the hemorrhage was absorbed. The time of absorption varies depending upon the site and the severity of hemorrhage. Intraventricular hemorrhage, petechial hemorrhage and subdural hematoma were absorbed rapidly in more than 70% of the exanimed cases, CT scanning 1 - 2 weeks after the onset revealed absorption of hemorrhage. However, the absorption delayed in intracerebral hematoma; CT scan taken after one month showed hemorrhagic lesions remaining in 75% of the cases. In nine cases who survived, following the absorption of the hemorrhagic lesions, cerebral atrophy was observed in 4 cases (44%), ventricular enlargement in 3 cases (33%), and complete recovery in 2 cases (22%). From these results, CT scanning for diagnosis of neonatal intracranial hemorrhage should be done before the hemorrhagic lesion is absorbed (within 7 days of the onset). Follow-up study by CT is important for observing changes and predicting prognosis of intracranial hemorrhage. (Ueda, J.)

  16. Utility of lytic bacteriophage in the treatment of multidrug-resistant Pseudomonas aeruginosa septicemia in mice

    Vinodkumar C

    2008-07-01

    Full Text Available Drug resistance is the major cause of increase in morbidity and mortality in neonates. One thousand six hundred forty-seven suspected septicemic neonates were subjected for microbiological analysis over a period of 5 years. Forty-two P. aeruginosa were isolated and the antibiogram revealed that 28 P. aeruginosa were resistant to almost all the common drugs used (multidrug-resistant. The emergence of antibiotic-resistant bacterial strains is one of the most critical problems of modern medicine. As a result, a novel and most effective approaches for treating infection caused by multidrug-resistant bacteria are urgently required. In this context, one intriguing approach is to use bacteriophages (viruses that kill bacteria in the treatment of infection caused by drug-resistant bacteria. In the present study, the utility of lytic bacteriophages to rescue septicemic mice with multidrug-resistant (MDR P. aeruginosa infection was evaluated. MDR P. aeruginosa was used to induce septicemia in mice by intraperitoneal (i.p. injection of 10 7 CFU. The resulting bacteremia was fatal within 48 hrs. The phage strain used in this study had lytic activity against a wide range of clinical isolates of MDR P. aeruginosa. A single i.p. injection of 3 x 10 9 PFU of the phage strain, administered 45 min after the bacterial challenge, was sufficient to rescue 100% of the animals. Even when treatment was delayed to the point where all animals were moribund, approximately 50% of them were rescued by a single injection of this phage preparation. The ability of this phage to rescue septicemic mice was demonstrated to be due to the functional capabilities of the phage and not to a nonspecific immune effect. The rescue of septicemic mice could be affected only by phage strains able to grow in vitro on the bacterial host used to infect the animals and when such strains are heat-inactivated, they lose their ability to rescue the infected mice. Multidrug-resistant bacteria have

    1984-01-01

    The symptoms of hypertensive putaminal hemorrhage and of middle cerebral artery occlusion are sometimes similar to each other. Hemorrhage sometimes occurs following cerebral infarction. We experienced 7 patients with hemorrhages localized in the basal ganglia following cerebral infarction. The CT findings of 55 patients with putaminal hemorrhage and 7 patients with hemorrhagic infarction localized at the basal ganglia were investigated retrospectively in order to discuss their characteristics. The high-density area (HD) of a putaminal hemorrhage was homogeneous on a plain CT within a week of the onset. There was a close correlation between the size of the HD and the timing of its disappearance. The HD with a maximum diameter of A cm generally disappeared A weeks after. On the other hand, the HD of a hemorrhagic infarction was lower in density than that of the putaminal hemorrhage. The HD of a hemorrhagic infarction generally disappeared earlier than that of a putaminal hemorrhage. Ring enhancement was visualized on contrast-enhanced CT (CECT) from 2 or 3 weeks after the onset in patients with putaminal hemorrhages except in the case of small hemorrhages (less than 1 cm diameter). Ring enhancement was also visualized in 6 out of 7 patients with hemorrhagic infarction; one of them was recognized within a week of the onset. Contrast enhancement of the cortex in the territory of the middle cerebral artery was visualized in 4 out of 7 patients with hemorrhagic infarction. This finding seems to indicate one characteristic of hemorrhagic infarction. (author)

    1981-01-01

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

    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.)

    Full Text Available Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate secondary injury. Deep knowledge of the injuries which are directly involved alterations of glucose, offers insight as cytotoxicity, neuronal death and metabolic dysregulations alter the prognosis of patients with spontaneous intracerebral hemorrhage.

  9. Intracranial hemorrhage of the mature newborn infant

    Takemine, Hisao

    1983-01-01

    Concerning four mature newborn infants with intracranial hemorrhage diagnosed by CT, the labour course, treatment, and prognoses were discussed. Of intracranial hemorrhage, 70.7% was small hemorrhage along the cerebellar tentorium and the falx cerebri, 12.2% subdural hemorrhage in the posterior cranial fossa, and 9.8% subdural hemorrhage in the fornex. Intraventricular or extradural hemorrhage was rarely found. The prognosis is determined by severeness of neurotic symptoms due to cerebral hypoxia. Subdural hemorrhage of the posterior cranial fossa resulted in cerebral palsy in one fifth of the cases, and in slight enlargement of the ventricle in three fifths. Subdural hematoma left porencephaly in one fourth of the patients, but the remaining recovered to normal. (Ueda, J.)

  10. Computed tomography of intraventricular hemorrhage

    Cho, Bum Shin; Shin, Kyoung Hee; Hahm, Chang Kok

    1982-01-01

    Computed tomography (CT) is a new non-invasive diagnostic imaging method, which has ability to differentiate C.S.F., hematoma, and even edematous brain from normal brain tissue. Prior to the introduction of the CT, the diagnosis of the intraventricular hemorrhage in living patients was difficult and was confirmed by surgery of autopsy. Intracranial hemorrhages are visible on the CT with density higher than brain tissue in acute phase. CT is an accurate method for detecting of intraventricular hemorrhage including detection of nature, location, amount, and associated changes. CT is also useful as a guidance and in the evaluation of fate of the hematomas by easily performable follow up studies. The causes of the intraventricular hemorrhages are hypertension, rupture of aneurysm, arteriovenous malformation, head trauma, brain tumor, and others. This study included evaluation of CT of 69 patients who show the high density in cerebral ventricular system during the period of 31 months from Feb. 1979 to Aug. 1981 in the Department of Radiology, College of Medicine, Hanyang University. The results were as follows. 1. Age distribution of the total 69 patient was broad ranging from 1 month to 80 years. 28% of patients were in the 6th decade. The mate to female ratio was 2 : 1. 2. The consciousness of patients at CT study: Those were conscious in 11 cases, stuporous in 41 cases and unconscious in 17 cases. 3. The causes of intraventricular hemorrhages were hypertension in 28 cases, head trauma in 12 cases, aneurysm in 4 cases, tumor in 2 cases and others in 23 cases. 4. 9 cases showed intraventricular hematomas only, other 60 cases showed associated intracranial hematomas: Those were intracerebral hematomas in 53 cases including 30 cases of basal ganglial and thalamic hematomas, subarachnoid hemorrhage in 17 cases, epidural hematomas in 3 cases, and subdural hematomas in 2 cases. 5. All cases of the intraventricular hematomas except one sowed hematoma in the lateral

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

  12. [Crimean-Congo hemorrhagic fever].

    Saijo, Masayuki; Moriikawa, Shigeru; Kurane, Ichiro

    2004-12-01

    Crimean-Congo hemorrhagic fever (CCHF) is an acute infectious disease caused by CCHF virus (CCHFV), a member of the family Bunyaviridae, genus Nairovirus. The case fatality rate of CCHF ranges from 10-40%. Because CCHF is not present in Japan, many Japanese virologists and clinicians are not very familiar with this disease. However, there remains the possibility of an introduction of CCHFV or other hemorrhagic fever viruses into Japan from surrounding endemic areas. Development of diagnostic laboratory capacity for viral hemorrhagic fevers is necessary even in countries without these diseases. At the National Institute of Infectious Diseases, Tokyo, Japan, laboratory-based systems such as recombinant protein-based antibody detection, antigen-capture and pathological examination have been developed. In this review article, epidemiologic and clinical data on CCHF in the Xinjiang Uygur Autonomous Region, compiled through field investigations and diagnostic testing utilizing the aforementioned laboratory systems, are presented. CCHFV infections are closely associated with the environmental conditions, life styles, religion, occupation, and human economic activities. Based on these data, preventive measures for CCHFV infections are also discussed.

  13. MR imaging of intraocular hemorrhage

    Saint-Louis, L.A.; Weiss, R.; Ellsworth, R.; Chang, S.; Deck, M.D.F.

    1987-01-01

    The authors evaluated with MR imaging 11 globes (nine patients) with spontaneous or traumatic intraocular hemorrhage. Subretinal blood was present in eight. Intravitreal bleeding was associated in seven and three subchoroidal. The ages of the hemorrhages ranged from 1 day to 6 months. Six of the subretinal and two subchoroidal cases had clotted blood with different intensity on the short TE images but were markedly hypointense on long TR/long TE images. The intravitreal blood was hyperintense on all sequences except in one. All imaging was performed with .5 T, 256 matrix, and 4- and 7- mm section thickness. Because of the varied appearance of hemorrhages, the authors scanned and are scanning two rabbits with intravitreal blood in vivo. Parameters include: 3-mm sections, T1, PD, T2 scans in .3-T and 1.5-T imagers. Initial results for the first 2 days show no change in signal intensity (hyperintense on all sequences). The T1 images show a diminishing intensity up to 8 days, and T2 scans remained hyperintense. These results so far correlate with the patient findings. The authors present the clinical findings and experimental correlation

    The purpose of this study was to analyze the angioarchitectures of cerebral arteriovenous malformation (AVM) and to determine whether there was correlation between angioarchitectures and patterns of intracranial hemorrhage (intracerebral, intraventricular, and both) in cerebral AVM. One hundred and twenty-eight patients who between November 1989 and December 1994 suffered supratentorial AVM with intracranial hemorrhage were studied retrospectively. Among 128 patients, intracerebral and intraventricular hemorrhage were seen in 68(53%) and 24 patients(19%), respectively, while both types were seen in the remaining 36 (28%). We analyzed the angioarchitectual characteristics of AVM, namely nidi, feeding arteries and draining veins, in three hemorrhagic groups of patients with intracerebral hemorrhage, intraventricular hemorrhage and both. The X 2 test or Fisher's exact test was used for statistical analysis. A cortically located nidus was most common in patients with intracerebral hemorrhage, while a periventricular location was most common in those with intraventricular hemorrhage (p<0.001). Location in the corpus callosum, choroid plexus, or intraventricular area was more frequent in the intraventricular than the intracerebral hemorrhagic group (p<0.05). Superficial venous drainage was most common in patients with intracerebral hemorrhage (p<0.001), and deep venous drainage in those with intraventricular hemorrhage (p=3D0.001). The angioarchitectual characteristics of cerebral arteriovenous malformation correlate significantly with patterns of intracranial hemorrhage, and awareness of the type of hemorrhage could help to manage patients and determine prognosis.=20

  15. Sutureless liver repair and hemorrhage control using laser-mediated fusion of human albumin as a solder.

    2001-07-01

    Major liver trauma has a high mortality because of immediate exsanguination and a delayed morbidity from septicemia, peritonitis, biliary fistulae, and delayed secondary hemorrhage. We evaluated laser soldering using liquid albumin for welding liver injuries. Fourteen lacerations (6 x 2 cm) and 13 nonanatomic resection injuries (raw surface, 8 x 2 cm) were repaired. An 805-nm laser was used to weld 53% liquid albumin-indocyanine green solder to the liver surface, reinforcing it by welding a free autologous omental scaffold. The animals were heparinized and hepatic inflow occlusion was used for vascular control. For both laceration and resection injuries, 16 soldering repairs were evaluated acutely at 3 hours. Eleven animals were evaluated chronically, two at 2 weeks and nine at 4 weeks. All 27 laser mediated-liver repairs had minimal blood loss compared with the suture controls. No dehiscence, hemorrhage, or bile leakage was seen in any of the laser repairs after 3 hours. All 11 chronic repairs healed without complication. This modality effectively seals the liver surface, joins lacerations with minimal thermal injury, and works independently of the patient's coagulation status.

    Clinical manifestations of adrenal hemorrhage vary depending on the degree and rate of hemorrhage, as well as the amount of adrenal cortex compromised by hemorrhage. We report here a case of neonatal adrenal hemorrhage that presented with late onset neonatal jaundice. The cause of adrenal hemorrhage was birth asphyxia.

  17. Intraretinal hemorrhages in cystoid macular edema.

    Bovino, J A; Kelly, T J; Marcus, D F

    1984-08-01

    Retinal hemorrhages can be associated with typical cystoid macular edema. We examined the fundus photographs and fluorescein angiograms of 313 eyes of 264 patients with documented cystoid macular edema to establish the incidence and characteristics of associated intraretinal hemorrhages. As we wanted to study only those hemorrhages unique to cystoid macular edema, we excluded 86 eyes because the patients had diseases known to be associated with retinal hemorrhages. These diseases included diabetes mellitus, branch retinal vein occlusion, hypertensive retinopathy, venous stasis retinopathy, and perifoveal telangiectasia. Of the remaining 227 eyes with cystoid macular edema, 56 (24.7%) were identified with retinal hemorrhages not associated with systemic disease. The hemorrhages were characteristically oval, round, or linear and frequently filled or partially filled the intraretinal cystoid space. In many patients, a blood-fluid level was observed.

  18. MR imaging of acute hemorrhagic brain infarction

    1989-01-01

    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)

  19. MR imaging of acute subarachnoid hemorrhage

    1987-01-01

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

    Perna, Robert; Temple, Jessica

    2015-01-01

    Background. Ischemic and hemorrhagic strokes have different pathophysiologies and possibly different long-term cerebral and functional implications. Hemorrhagic strokes expose the brain to irritating effects of blood and ischemic strokes reflect localized or diffuse cerebral vascular pathology. Methods. Participants were individuals who suffered either an ischemic (n = 172) or hemorrhagic stroke (n = 112) within the past six months and were involved in a postacute neurorehabilitation program....

  1. Dickeya dadantii, a plant pathogenic bacterium producing Cyt-like entomotoxins, causes septicemia in the pea aphid Acyrthosiphon pisum.

    2012-01-01

    Dickeya dadantii (syn. Erwinia chrysanthemi) is a plant pathogenic bacteria that harbours a cluster of four horizontally-transferred, insect-specific toxin genes. It was recently shown to be capable of causing an acute infection in the pea aphid Acyrthosiphon pisum (Insecta: Hemiptera). The infection route of the pathogen, and the role and in vivo expression pattern of these toxins, remain unknown. Using bacterial numeration and immunolocalization, we investigated the kinetics and the pattern of infection of this phytopathogenic bacterium within its insect host. We compared infection by the wild-type strain and by the Cyt toxin-deficient mutant. D. dadantii was found to form dense clusters in many luminal parts of the aphid intestinal tract, including the stomach, from which it invaded internal tissues as early as day 1 post-infection. Septicemia occurred soon after, with the fat body being the main infected tissue, together with numerous early infections of the embryonic chains showing embryonic gut and fat body as the target organs. Generalized septicemia led to insect death when the bacterial load reached about 10(8) cfu. Some individual aphids regularly escaped infection, indicating an effective partial immune response to this bacteria. Cyt-defective mutants killed insects more slowly but were capable of localisation in any type of tissue. Cyt toxin expression appeared to be restricted to the digestive tract where it probably assisted in crossing over the first cell barrier and, thus, accelerating bacterial diffusion into the aphid haemocel. Finally, the presence of bacteria on the surface of leaves hosting infected aphids indicated that the insects could be vectors of the bacteria.

    2012-01-01

    Full Text Available Aim: Isolation, dark field detection and microscopic agglutination test (MAT are considered ―gold standard‖ tests for diagnosis of Leptospirosis. Several PCR assays are reported but very few have been evaluated for detection of Leptospirosis. Therefore, this study was undertaken. This study aims to design and standardize polymerase chain reaction (PCR - based DNA sequencing technique for the detection of pathogenic Leptospira from peripheral blood of patients clinically diagnosed with septicemia. Methodology and Results: Two hundred and seven (207 blood samples from patients were diagnosed with septicemia which includes 100 bacterial (other than Leptospira culture positive and 107 bacterial culture negative samples were studied. Primers for Nested PCR targeting LipL32 gene of Leptospira interrogans were designed and the specificity of primers was tested against serum samples positive/negative by either MAT or dark field microscopy. PCR amplified products were further confirmed by DNA sequencing. The standardized nPCR was sensitive and specific to Leptospira interrogans. Twenty-one (21% out of 100 culture positive blood samples, three (2.8% out of 107 culture negative samples showed nPCR positivity and were confirmed as Leptospira interrogans by DNA sequencing (p<0.001. A sensitive nPCR specific to Leptospira interrogans was developed. Conclusion, significance and impact of study: The p value (<0.001 signifies that Leptospira is commonly associated with other bacteria circulating in blood indicating that a decreased immune status is created primarily by a bacterium with enhanced possibility of development of Leptospiral infection probably be of an endogenous origin.

  4. Obstetric Emergencies: Shoulder Dystocia and Postpartum Hemorrhage.

    Dahlke, Joshua D; Bhalwal, Asha; Chauhan, Suneet P

    2017-06-01

    Shoulder dystocia and postpartum hemorrhage represent two of the most common emergencies faced in obstetric clinical practice, both requiring prompt recognition and management to avoid significant morbidity or mortality. Shoulder dystocia is an uncommon, unpredictable, and unpreventable obstetric emergency and can be managed with appropriate intervention. Postpartum hemorrhage occurs more commonly and carries significant risk of maternal morbidity. Institutional protocols and algorithms for the prevention and management of shoulder dystocia and postpartum hemorrhage have become mainstays for clinicians. The goal of this review is to summarize the diagnosis, incidence, risk factors, and management of shoulder dystocia and postpartum hemorrhage. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. Surgical management of spontaneous hypertensive brainstem hemorrhage

    Bal Krishna Shrestha

    2015-09-01

    Full Text Available Spontaneous hypertensive brainstem hemorrhage is the spontaneous brainstem hemorrhage associated with long term hypertension but not having definite focal or objective lesion. It is a catastrophic event which has a poor prognosis and usually managed conservatively. It is not uncommon, especially in eastern Asian populations, accounting approximately for 10% of the intracerebral hemorrhage. Before the advent of computed tomography, the diagnosis of brainstem hemorrhage was usually based on the clinical picture or by autopsy and believed to be untreatable via surgery. The introduction of computed tomography permitted to categorize the subtypes of brainstem hemorrhage with more predicted outcome. Continuous ongoing developments in the stereotactic surgery and microsurgery have added more specific surgical management in these patients. However, whether to manage conservatively or promptly with surgical evacuation of hematoma is still a controversy. Studies have shown that an accurate prognostic assessment based on clinical and radiological features on admission is critical for establishing a reasonable therapeutic approach. Some authors have advocate conservative management, whereas others have suggested the efficacy of surgical treatment in brainstem hemorrhage. With the widening knowledge in microsurgical techniques as well as neuroimaging technology, there seems to have more optimistic hope of surgical management of spontaneous hypertensive brainstem hemorrhage for better prognosis. Here we present five cases of severe spontaneous hypertensive brainstem hemorrhage patients who had undergone surgery; and explore the possibilities of surgical management in patients with the spontaneous hypertensive brainstem hemorrhage.

    1985-01-01

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

  7. The Roles of Thrombospondins in Hemorrhagic Stroke

    Xuan Wu

    2017-01-01

    Full Text Available Hemorrhagic stroke is a devastating cerebrovascular disease with significant morbidity and mortality worldwide. Thrombospondins (TSPs, as matricellular proteins, belong to the TSP family which is comprised of five members. All TSPs modulate a variety of cellular functions by binding to various receptors. Recently, TSPs gained attention in the area of hemorrhagic stroke, especially TSP-1. TSP-1 participates in angiogenesis, the inflammatory response, apoptosis, and fibrosis after hemorrhagic stroke through binding to various molecules including but not limited to CD36, CD47, and TGF-β. In this review, we will discuss the roles of TSPs in hemorrhagic stroke and focus primarily on TSP-1.

    2016-07-01

    Full Text Available Leptospirosis is one of the most widespread zoonoses in the world, although the mechanisms responsible for the pathogenesis of spirochetes of the genus Leptospira are largely unknown. Human infection occurs either by direct contact with infected animals or indirectly, through contact with water or soil contaminated with urine, as the spirochetes easily penetrate human skin. The present report exposes the case of a female patient, diagnosed with leptospirosis after having had contact with a dog infected by Leptospira sp. that developed pulmonary hemorrhage, acute respiratory distress syndrome and acute renal failure.

  9. Subarachnoid hemorrhage in pituitary tumor

    Ashis Patnaik

    2013-01-01

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

    1989-01-01

    Ten cases of primary brain tumor presenting as intracranial hemorrhage were studied in terms of the radiological and histological findings. The cases having hemorrhage in the tumor, as established through CT or histologically, were excluded if their onsets were not sudden due to intracranial hemorrhages. The results obtained may be summarized as follows: 1) From an anatomical point of view, cerebral subcortical hemorrhages account for 80%; hemorrhages in the cerebellopontine angle, 10%, and hemorrhages in the basal ganglia, 10%. 2) Plain CT findings showed perifocal low-density areas within 24 hours after onset in all 10 cases. 3) Enhanced CT findings showed enhanced areas in 4 or 6 cases. 4) Angiographic findings revealed abnormalities besides the mass effect in 5 of the 10 cases. 4) Angiographic findings revealed abnormalities besides the mass effect in 5 of the 10 cases. 5) From a histological point of view, glioblastomas account for 30%; malignant astrocytomas, 20%; astrocytomas, 20%; malignant ependymomas, 10%; hemangioblastoma, 10%, and transitional meningiomas, 10%. In conclusion, a perifocal low-density area on CT within 24 hours after onset is the most meaningful indication of intracranial hemorrhage originating from a brain tumor. A histological 'perinuclear halo' in an astrocytoma as an artifact due to hemorrhage may often be misleading in diagnosing mixed oligo-astrocytomas. (author)

  18. Recurrent Bleeding After Perimesencephalic Hemorrhage.

    Kauw, Frans; Velthuis, Birgitta K; Kizilates, Ufuk; van der Schaaf, Irene C; Rinkel, Gabriel J E; Vergouwen, Mervyn D I

    2017-12-01

    Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only 1 well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. We describe a patient with PMH without antithrombotic treatment who had 2 episodes of recurrent bleeding on the day of ictus. To validate the radiologic findings, we conducted a case-control study. Six neuroradiologists and 2 neuroradiology fellows performed a blinded assessment of serial unenhanced head computed tomography (CT) scans of 8 patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with perimesencephalic bleeding pattern and basilar artery aneurysm) to investigate a potential increase in amount of subarachnoid blood. A 56-year-old woman with a perimesencephalic bleeding pattern and negative CT angiography had 2 episodes after the onset headache with a sudden increase of the headache. Blinded assessment of serial head CT scans of 8 patients with a perimesencephalic bleeding pattern identified the patient who was clinically suspected to have 2 episodes of recurrent bleeding to have an increased amount of subarachnoid blood on 2 subsequent CT scans. Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, the prognosis of PMH is excellent. Copyright © 2017 Elsevier Inc.

  19. Hydrocephalus associated with subarachnoid hemorrhage

    Nosaka, Yoshiki

    1981-01-01

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

  20. Lateral type of intracerebral hemorrhage

    Yamagami, Tatsuhito; Gotoh, Yasunobu; Imataka, Kiyoharu; Niijima, Kyo; Handa, Hajime.

    1987-01-01

    The magnetic resonance imaging (MRI) of intracerebral hemorrhages (lateral type) was studied. The strength of the magnetic field was 0.2 Tesla. Four cases were studied with inversion recovery (IR) and saturation recovery (SR) images. The findings of the acute stage (within 1 week) were a central isointensity and a peripheral low intensity on the IR image. On the SR image we recognized a central isointensity and a peripheral high intensity holding a faintly high intensity area around the hematoma. The findings of the subacute stage (from 1 to 3 weeks) were characterized by a central isointensity and a peripheral high-intensity ring, with a low-intensity area outside the hematoma on the IR image. A widespread high-intensity area including the hematoma itself and the surrounding white matter was observed on the SR image. The findings of the chronic stage (over 3 weeks) were the disapperance of a high-intensity ring and a change to a low-intensity area on the IR image. The hematoma itself and surrounding white matter had a high intensity, which has decreased in size in comparison with that of the subacute stage. The hypointensity rim was found in the immediately adjacent part of the original hematoma on the SR image. The MRI of a small hematoma 70 days from the onset showed an almost normal brain structure. Some magnetic resonance findings of intracerebral hemorrhage were reviewed. (author)

  1. Medulla Oblongata Hemorrhage and Reverse Takotsubo Cardiomyopathy.

    Gobeske, Kevin T; Sarano, Maurice E; Fugate, Jennifer E; Wijdicks, Eelco F

    2017-12-19

    Acute brain injury with strong surges of adrenergic outflow has resulted in takotsubo cardiomyopathy, but there are surprisingly few reports of takotsubo cardiomyopathy after intracranial hemorrhage, and none have been described from hemorrhage within the brainstem. We describe a patient with reverse and reversible cardiomyopathy following a hemorrhage in the lateral medulla oblongata. While it is limited in size, the location of the hemorrhage caused acute systolic failure with left ventricular ejection fraction of 27% and vasopressor requirement for cardiogenic shock and pulmonary edema. There was full recovery after 7 days. Detailed case report. Hemorrhage into medulla oblongata pressor centers may result in acute, reversible, stress-induced cardiomyopathy, affirming the adrenergic origin of this condition.

  2. Neck and scleral hemorrhage in drowning.

    Alexander, Russell T; Jentzen, Jeffrey M

    2011-03-01

    The determination of the cause and manner of death for a body recovered from the water can be difficult because of a lack of autopsy findings specific for drowning. This case report describes a 30-year-old man found submerged at the bottom of a hotel pool. An autopsy revealed scleral hemorrhages and fascial hemorrhages of multiple muscles of the anterior and posterior neck bilaterally. No evidence of traumatic injury was on the surface of the body. An investigation by law enforcement found no evidence of foul play. The occurrence of petechial and neck hemorrhage in a body recovered from the water is controversial, and a review of this literature will be given. We suggest that fascial hemorrhages of the muscles of the neck, as well as cephalic hemorrhages, can be explained by drowning-related elevated central venous pressure that is communicated to the head through the valveless veins of the neck. © 2010 American Academy of Forensic Sciences.

  3. A case of idiopathic omental hemorrhage

    Toshimitsu Hosotani

    2016-05-01

    Full Text Available With the exception of trauma, intraperitoneal hemorrhage in young women is caused by the high frequency of ectopic pregnancy and ovarian bleeding. Here, we describe a case of idiopathic omental hemorrhage, which is a rare cause of intraperitoneal hemorrhage. Intraperitoneal hemorrhage was suspected in a 38-year-old Japanese woman based on contrast-enhanced computed tomography. Her last menstrual period was 23 days prior, and ovarian bleeding was considered based on bloody ascites revealed by culdocentesis. She underwent emergency surgery for hypovolemic shock. Although both ovaries were of normal size and no abnormal findings were observed, we performed a partial omentectomy because multiple clots were attached only to the greater omentum. Postoperatively, no rebleeding occurred, and she was discharged 11 days after the surgery. Because she did not have a clear history of trauma and underlying disease, idiopathic omental hemorrhage was diagnosed.

  4. A case of traumatic intraventricular hemorrhage

    1980-01-01

    CT scan is recognized to be a rapid, noninvasive and informative examination in evaluation of the head injured patient. It is also possible to evaluate the presence of the intracerebral hematoma without remarkable mass effect, cerebral contusion, associated cerebral edema and ventricular hemorrhage. We present a case of traumatic intraventricular hemorrhage. The patient was a 40-year-old male admitted to our hospital in a drowsy state following a fall from about one meter high. Craniogram showed a linear fracture in the left parietotemporal regions. In the CT scan, intraventricular hemorrhage associated with subarachnoid hemorrhage without intracerebral hematoma was shown. A symmetrical moderate dilatation of both lateral ventricles was also shown. Cerebral angiography revealed no abnormality. His condition deteriorated progressively, so ventricular drainage was performed, but he expired 5 days later. Considering this case, the mechanisms of pure intraventricular hemorrhage following head injury were discussed. (author)

    To establish risk of hemorrhage in patients with varices compared to those without, determine additional risk factors, and make evidence-based treatment recommendations. Retrospective cohort study. Patients who were vocal performers presenting for care during a 24-month period were analyzed to determine incidence of hemorrhage. Patients with varices were compared to those without. Demographic information and examination findings (presence, location, character, and size of varices; presence of mucosal lesions or paresis) were analyzed to determine predictors of hemorrhage. A total of 513 patients (60.4% female, mean age 36.6 years ± 13.95 years) were evaluated; 14 patients presenting with hemorrhage were excluded. One hundred and twelve (22.4%) patients had varices; 387 (77.6%) did not. The rate of hemorrhage in patients with varices was 2.68% at 12 months compared to 0.8% in patients without. Cox proportional hazard regression analysis revealed a hazard ratio of 10.1 for patients with varix developing hemorrhage compared to nonvarix patients (P hemorrhage was 3.3 cases per 1,000 person-months for varix patients compared to 0.5 cases per 1,000 person-months in the nonvarix group. There was no significant difference in the incidence of paresis, mucosal lesions, location of varix (left or right side; medial or lateral), or varix morphology (pinpoint, linear, lake) between patients who hemorrhaged and those that did not. The presence of varices increases the risk of hemorrhage. Varix patients had 10 times the rate of hemorrhage compared to nonvarix patients, although the overall incidence is low. This data may be used to inform treatment of patients with varices. 4. Laryngoscope, 126:1163-1168, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

  6. Experimental induction of motile Aeromonas septicemia in channel catfish (Ictalurus punctatus by waterborne challenge with virulent Aeromonas hydrophila

    Dunhua Zhang

    2016-05-01

    Full Text Available Motile Aeromonas septicemia (MAS, caused by virulent clonal isolates of Aeromonas hydrophila (vAh, is emerging as a major disease in catfish (Ictalurus punctatus aquaculture in the Southeastern United States. Predisposing conditions leading to vAh infection in catfish were however largely unknown. The objective of this study was to investigate factors that predispose catfish to vAh infection and establish a waterborne challenge model that mimics natural occurrence of MAS. Results of this study indicated that wounding on the fish body surface was one of the key factors that predisposed catfish to vAh infection via waterborne route. Relatively uniform wounds were created by clipping part of the fish adipose fin. Adipose fin clipped (Af-clipped fish behaved normally in terms of swimming and feeding and no mortality occurred in the control treatment (a mock challenge. When subjected to challenge in vAh-infected water, Af-clipped fish were highly susceptible, showing typical symptoms of MAS observed in the field. The mortality rate of Af-clipped fish was significantly associated with vAh concentration, challenge time and water temperature. About 90% mortality occurred within 48 h when Af-clipped fish were challenged for 1 h with vAh at the concentration of 2 × 107 colony forming units per mL of water (27 ± 1 °C. The waterborne challenge model was further tested using four field isolates including A. hydrophila and A. veronii. All vAh isolates caused about 90% mortality of Af-clipped fish and one isolate of Aeromonas veronii caused no mortality under the same challenge conditions. The waterborne challenge model described in this study would facilitate urgently-needed studies of MAS prevention (such as wound avoidance and healing and control (such as prophylactic vaccination; antibiotics treatment and probiotics screening.

  7. In Vivo Efficacy of Plazomicin Alone or in Combination with Meropenem or Tigecycline against Enterobacteriaceae Isolates Exhibiting Various Resistance Mechanisms in an Immunocompetent Murine Septicemia Model.

    Abdelraouf, Kamilia; Kim, Aryun; Krause, Kevin M; Nicolau, David P

    2018-06-04

    Background : Plazomicin is a next-generation aminoglycoside with potent in vitro activity against multidrug- and carbapenem-resistant Enterobacteriaceae. The objective of this study was to assess the efficacy of plazomicin exposure, alone and in combination with meropenem or tigecycline, against Enterobacteriaceae in the immunocompetent murine septicemia model. Methods : ICR mice were inoculated intraperitoneally with bacterial suspensions. Eight Enterobacteriaceae isolates with wide ranges of plazomicin, meropenem and tigecycline MICs were utilized. Treatment mice were administered plazomicin, meropenem or tigecycline human-equivalent doses alone or in combinations of plazomicin/meropenem and plazomicin/tigecycline. Treatments were initiated 1h post-infection and continued for 24h. Efficacy was assessed by survival through 96h. Results : Compared with controls, plazomicin monotherapy produced significant improvement in survival for all isolates (P32 and 2 mg/L, respectively), combination therapies showed significant reduction in mortality compared with any monotherapy (P<0.05). Conclusion : Plazomicin monotherapy resulted in improved survival in the immunocompetent murine septicemia model, notably for isolates with plazomicin MIC ≤4 mg/L. As evidenced by our current data, co-administration of meropenem or tigecycline could potentially lead to further improvement in survival. These data support a role for plazomicin in the management of septicemia due to Enterobacteriaceae with plazomicin MIC ≤4 mg/L, including carbapenem-resistant isolates.

    Full Text Available Acute hemorrhagic edema of infancy is a rare form of leukocytoclastic vasculitis. Mostly it appears under three years of age and is characterized by purpuric skin lesions, fever and edema. A three years-old boy, who has cough and coryzea was admitted to our clinic for fever and red spots on legs and arms. In physical examination; ecimotic skin lesions on right ear, face, arms, dorsal of the hands, buttocks, legs and dorsal of the feet were found. In the laboratory tests acute phase reactants were elevated and blood coagulation tests were in normal range. Hepatit A,B,C and TORCH markers were negative. Punch biopsy obtained from gluteal area showed leukositoclastic vasculity. Focal fibrinogen accumulation was detected by immun fluorescent microscopy. Regression on lesions was not observed despite supportive therapy, so prednisolone (1 mg/kg/day therapy was started. On the third day of the steroid therapy, complete recovery was achived.

    Carette, Marie-France; Nedelcu, Cosmina; Tassart, Marc; Grange, Jean-Didier; Wislez, Marie; Khalil, Antoine

    2009-01-01

    This pictorial review is based on our experience of the follow-up of 120 patients at our multidisciplinary center for hereditary hemorrhagic telangiectasia (HHT). Rendu-Osler-Weber disease or HHT is a multiorgan autosomal dominant disorder with high penetrance, characterized by epistaxis, mucocutaneous telangiectasis, and visceral arteriovenous malformations (AVMs). The research on gene mutations is fundamental and family screening by clinical examination, chest X-ray, research of pulmonary shunting, and abdominal color Doppler sonography is absolutely necessary. The angioarchitecture of pulmonary AVMs can be studied by unenhanced multidetector computed tomography; however, all other explorations of liver, digestive bowels, or brain require administration of contrast media. Magnetic resonance angiography is helpful for central nervous system screening, in particular for the spinal cord, but also for pulmonary, hepatic, and pelvic AVMs. Knowledge of the multiorgan involvement of HHT, mechanism of complications, and radiologic findings is fundamental for the correct management of these patients.

  10. Management of aneurysmal subarachnoid hemorrhage.

    Etminan, N; Macdonald, R L

    2017-01-01

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

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

    Full Text Available Crimean-Congo hemorrhagic fever (CCHF was first described in the Crimea in 1944 and then in 1956 in congo. CCHF is a viral hemorrhagic fever of the Nairovirus group that belongs to Bunyaviridae family virus. It is transmitted to human by tick bite. The most efficient and common tick that is the vectors of CCHF is a member of the Hyalomma genus which infected many mammals such as livestock, this tick is the main reservoire of virus in nature. Humans also become infected with CCHF virus by direct contact with blood or other infected tissues from livestock or human patients (nosocomial infection. Disease has been found in saharic Africa, Eastern Europe, Pakistan, India and Middle East (specially Iran and Iraq.

    The author in an attempt to evaluate hemodynamic changes in the clinical stages of Korean hemorrhagic fever measured plasma volume, cardiac output and effective renal plasma flow utilizing radioisoto as during various phases of the disease. Cardiac output was measured by radiocardiography with external monitoring method using RIHSA. Effective renal plasma flow was obtained from blood clearance curve drawn by external monitoring after radiohippuran injection according to the method described by Razzak et al. The study was carried out in thirty-eight cases of Korean hemorrhagic fever and the following conclusions were obtained. 1) Plasma volume was increased in the patients during the oliguric and hypertensive-diuretic phases, while it was normal in the patients during the normotensive-diuretic phase. 2) Cardiac index was increased in the patients during the oliguric phase and was slightly increased in the patients at the hypertensive diuretic phase. It was normal in the other phases. 3) Total peripheral resistance was increased in the hypertensive patients during diuretic phase, while it was normal in the rest of phases. 4) Effective renal plasma flow was significantly reduced in the patients during the oliguric and diuretic phases as well as at one month after the oliguric onset. There was no significant difference between the oliguric and the early diuretic phases. Renal plasma flow in the group of patients at one month after the oliguric onset was about 45% of the normal, however, it returned to normal level at six months after the onset. 5) Clinical syndrome of relative hypervolemia was observed in some patients during the oliguric phase or hypertensive diuretic phase. Characteristic hemodynamic findings were high cardiac output and normal to relatively increased peripheral resistance these cases. Relatively increased circulating blood volumes due to decreased effective vascular space was suggested for the mechanism of relative hypervolemia. 6) Cardiac

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

    Prior to the introduction of computed tomography, the clinical and radiological diagnosis of the intraventricular hemorrhage in living patients was difficult. C.T. scanning is an invaluable investigation providing the rapid and noninvasive diagnosis of intracerebral and intraventricular hemorrhage. It reliably demonstrates the presence and distribution of fresh blood within the ventricular system. C.T. is also useful as a surgical guidance and in the evaluation of fate of the hematoma by easily performable follow-up studies. We reviewed 31 cases of intraventricular hemorrhage in C.T. in the department of radiology of Ewha Womans University Hospital during the period from August, 1982 to August, 1983. The results were as follows: 1. The most patients were encountered in the 5th decade and the male to female ratio was 1.2 : 1. 2. Hypertension was the main cause of the intraventricular hemorrhage; 18 out of 31 patients. Remaining 13 patients were caused by hypoxia, aneurysm, Moya Moya disease, coagulation defect, trauma and undetermined etiology. 3. 18 out of 31 patients showed hemorrhage in the lateral ventricles only and all ventricles in 10 patients. 4. 28 out of 31 patients showed associated with intracranial hematoma; Those were intracerebral hematomas in 16 patients, intracerebral hematoma with subarachnoid hemorrhage in 4 patients and extracerebral hematoma in 2 patients. 5. Outcome was assessed using the Glasgow scale. According to them, the total mortality rates was 54.8%, however, 32.3% of patients returned to normal or minor disability. Patients, who had hypertension and marked degree of hemorrhage in the ventricular systems had a poor outcome. Patients with only ventricular hemorrhage had better outcome than associated intracranial hematoma. 6. 16 out of 31 patients were treated by surgical methods and 15 out of 31 patients by conservative methods. 75% of patients were died in conservative treatment. 7.

    We describe a hemorrhagic chondroid chordoma involving the sella turcica with suprasellar extension. The CT and MRI appearances mimiked a hemorrhagic pituitary adenoma. Chondroid chordoma is a variant composed of elements of both chordoma and cartilaginous tissue. An uncommon bone neoplasm, located almost exclusively in the spheno-occipital region, it is usually not considered in the differential diagnosis of a tumor with acute hemorrhage in the sellar region. We discuss the clinical and radiological characteristics which may allow one to differentiate chondroid chordoma from other tumors of this area. (orig.) With 3 figs., 9 refs.

    There are diverse etiologies of diffuse pulmonary hemorrhage, so specific diagnosis may be difficult. Conventional radiography tends to be misleading as hemoptysis may lacking in patients with hemorrhagic anemia. Diffuse pulmonary hemorrhage should be differentiated from focal pulmonary hemorrhage resulting from chronic bronchitis, bronchiectasis, active infection (tuberculosis) neoplasia, trauma, or embolism.

  1. CT findings of subarachnoid hemorrhage due to ruptured cerebral aneurysm with fundal hemorrhage

    Kashihara, Kengo; Yamashima, Tetsumori; Hasegawa, Takeshi; Kida, Shinya; Nitta, Hisashi; Yamamoto, Shinjiro

    1985-01-01

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

    2018-01-01

    Full Text Available Introduction. Pasteurella multocida is a gram-negative coccobacillus pathogenic to animals. It can cause infection in humans by a bite, scratch, or lick from a cat or dog. P. multocida can cause a variety of infections in humans, including cellulitis, osteomyelitis, endocarditis, peritonitis, and septic shock. Case Presentation. A 56-year-old male presented to our hospital with a 2-day history of fever, abdominal pain, nausea, and vomiting. He denied exposure to cats, dogs or other pets. He had severe respiratory distress requiring ventilator support, profound septic shock requiring multiple vasopressors, severe lactic acidosis, and renal failure requiring emergent hemodialysis. Blood cultures confirmed the presence of P. multocida. The patient subsequently died of cardiopulmonary arrest due to multiorgan failure with refractory shock. Conclusion. P. multocida septicemia can lead to septic shock. Early identification of this organism may decrease mortality. Although our patient had no known cat or dog exposure, physicians should enquire about a history of animal exposure when a patient presents with an infection with no obvious cause.

    2015-04-01

    To quantify the contribution of placenta accreta to the rate of postpartum hemorrhage and severe postpartum hemorrhage. All hospital deliveries in Canada (excluding Quebec) for the years 2009 and 2010 (N=570,637) were included in a retrospective cohort study using data from the Canadian Institute for Health Information. Placenta accreta included placental adhesion to the uterine wall, musculature, and surrounding organs (accreta, increta, or percreta). Severe postpartum hemorrhage included postpartum hemorrhage with blood transfusion, hysterectomy, or other procedures to control bleeding (including uterine suturing and ligation or embolization of pelvic arteries). Rates, rate ratios, population-attributable fractions (ie, incidence of postpartum hemorrhage attributable to placenta accreta), and 95% confidence intervals (CIs) were estimated. Logistic regression was used to quantify associations between placenta accreta and risk factors. The incidence of placenta accreta was 14.4 (95% CI 13.4-15.4) per 10,000 deliveries (819 cases among 570,637 deliveries), whereas the incidence of placenta accreta with postpartum hemorrhage was 7.2 (95% CI 6.5-8.0) per 10,000 deliveries. Postpartum hemorrhage among women with placenta accreta was predominantly third-stage hemorrhage (41% of all cases). Although placenta accreta was strongly associated with postpartum hemorrhage (rate ratio 8.3, 95% CI 7.7-8.9), its low frequency resulted in a small population-attributable fraction (1.0%, 95% CI 0.93-1.16). However, the strong association between placenta accreta and postpartum hemorrhage with hysterectomy (rate ratio 286, 95% CI 226-361) resulted in a population-attributable fraction of 29.0% (95% CI 24.3-34.3). Placenta accreta is too infrequent to account for the recent temporal increase in postpartum hemorrhage but contributes substantially to the proportion of postpartum hemorrhage with hysterectomy.

  5. Hemorrhage-Adjusted Iron Requirements, Hematinics and Hepcidin Define Hereditary Hemorrhagic Telangiectasia as a Model of Hemorrhagic Iron Deficiency

    Finnamore, Helen; Le Couteur, James; Hickson, Mary; Busbridge, Mark; Whelan, Kevin; Shovlin, Claire L.

    2013-01-01

    Background Iron deficiency anemia remains a major global health problem. Higher iron demands provide the potential for a targeted preventative approach before anemia develops. The primary study objective was to develop and validate a metric that stratifies recommended dietary iron intake to compensate for patient-specific non-menstrual hemorrhagic losses. The secondary objective was to examine whether iron deficiency can be attributed to under-replacement of epistaxis (nosebleed) hemorrhagic iron losses in hereditary hemorrhagic telangiectasia (HHT). Methodology/Principal Findings The hemorrhage adjusted iron requirement (HAIR) sums the recommended dietary allowance, and iron required to replace additional quantified hemorrhagic losses, based on the pre-menopausal increment to compensate for menstrual losses (formula provided). In a study population of 50 HHT patients completing concurrent dietary and nosebleed questionnaires, 43/50 (86%) met their recommended dietary allowance, but only 10/50 (20%) met their HAIR. Higher HAIR was a powerful predictor of lower hemoglobin (p = 0.009), lower mean corpuscular hemoglobin content (pstopped. Conclusions/significance HAIR values, providing an indication of individuals’ iron requirements, may be a useful tool in prevention, assessment and management of iron deficiency. Iron deficiency in HHT can be explained by under-replacement of nosebleed hemorrhagic iron losses. PMID:24146883

    Full Text Available "nGerminal matrix-intraventricular hemorrhage (IVH is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. The importance of the lesion relates not only to its high incidence but to their attendant complications (IC: hydrocephalus. Brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and hydrocephalus. In this study we have used brain sonography for detection of intraventricular hemorrhage and post hemorrhagic hydrocephalus and their incidences. The studied population was consisted of premature neonate (birth weight equal or less than 1500g and gestational age equal or less than 37 weeks who admitted in Mofid Hospital NICU (Tehran, Iran during a one year period. For all neonate (including criteria brain sonography in first week of life was done and in presence of IVH, serial Brain sonography was done weekly for detection of hydrocephalus. A total of 57 neonate entered the study. Intraventicular-germinal matrix hemorrhage was seen in 64.4% (35 patients. Forty percent of patients with intraventricular-germinal matrix hemorrhage had grade I, 11% grade II, 25.7% grade III, 2.8% grade VI. Hydrocephalus was detected in 20 percent of patients who had intraventricular-germinal matrix hemorrhage. That incidence of IVH in our study in comparison with other area and situation is higher. Hydrocephaly had direct relation with severity of IVH. This shows that with control of risk factor of IVH, we can control Post hemorrhagic hydrocephalus.

    To report bilateral hemorrhagic retinopathy in an adult female subject after lumbar spinal surgery and seizure. A 38-year-old woman presented with bilateral blurry vision and spots in the visual field. The patient had lumbar spondylosis surgery that was complicated by a dural tear with persistent cerebrospinal fluid leak. Visual symptoms started immediately after witnessed seizure-like activity. At presentation, visual acuity was 20/100 and 20/25 in the right and left eye, respectively. Dilated fundus examination demonstrated bilateral hemorrhagic retinopathy with subhyaloid, intraretinal, and subretinal involvement. At 4-month follow-up, visual acuity improved to 20/60 and 20/20 in the right and left eye, respectively. Dilated fundus examination and fundus photography showed resolution of retinal hemorrhages in both eyes. The first case of bilateral hemorrhagic retinopathy after lumbar spondylosis surgery and witnessed seizure in an adult was reported. Ophthalmic examination may be warranted after episodes of seizure in adults.

    Full Text Available A 33-year-old man who presented with prolonged epigastric pain was referred to our hospital. He had experienced recurrent epistaxis and had a family history of hereditary hemorrhagic telangiectasia. Computed tomography and magnetic resonance imaging revealed splenomegaly and a 9 cm hypervascular mass in his spleen. Computed tomography also showed a pulmonary arteriovenous malformation and heterogeneous enhancement of the liver parenchyma, suggesting the presence of arteriosystemic shunts and telangiectases. Based on these findings, the patient was definitely diagnosed with hereditary hemorrhagic telangiectasia according to Curaçao criteria. He underwent splenectomy, and his symptoms disappeared after surgery. Pathological examination of the resected specimen revealed that the hypervascular lesion of the spleen was not a tumor but was composed of abnormal vessels associated with hereditary hemorrhagic telangiectasia. Symptomatic splenic involvement may be a rare manifestation of hereditary hemorrhagic telangiectasia but can be revealed by imaging modalities.

    The author analysed experience in the embolization of the abdominal vessels in 79 patients with diseases and lesions of the peritoneal cavity and retroperitoneal space accompanied by life threatening hemorrhage. In 51 cases embolization was used as an independent method of hemorrhage arrest and in 28 cases for patients' preoperative preparation. A hemostatic sponge combined with a superselective administration of 150-200 ml of aminocaproic acid was used as an emboilizing material. Complications attributed to embolization were noted in 5 patients: pancreatitis, subdiaphragmatic abscess, paranephritis, ischemia of the gluteal soft tissues, sciatic neuritis. An analysis has shown that urgent embolization of the abdominal vessels in diseases and lesions of the organs of the peritoneal cavity and retroperitoneal space accompanied by massive hemorrhage, can be used as an independent method for hemorrhage arrest

    Massive hemorrhage is associated with coagulopathy and high mortality. The transfusion guidelines up to 2006 recommended that resuscitation of massive hemorrhage should occur in successive steps using crystalloids, colloids and red blood cells (RBC) in the early phase, and plasma and platelets...... in the late phase. With the introduction of the cell-based model of hemostasis in the mid 1990ties, our understanding of the hemostatic process and of coagulopathy has improved. This has contributed to a change in resuscitation strategy and transfusion therapy of massive hemorrhage along with an acceptance...... outcome, although final evidence on outcome from randomized controlled trials are lacking.

    2008-07-01

    To estimate the frequency and volume of fetomaternal hemorrhage during external cephalic version for term breech singleton fetuses and to identify risk factors involved with this complication. A prospective observational study was performed including all patients undergoing a trial of external cephalic version for a breech presentation of at least 36 weeks of gestation between 1987 and 2001 in our center. A search for fetal erythrocytes using the standard Kleihauer-Betke test was obtained before and after each external cephalic version. The frequency and volume of fetomaternal hemorrhage were calculated. Putative risk factors for fetomaternal hemorrhage were evaluated by chi(2) test and Mann-Whitney U test. A Kleihauer-Betke test result was available before and after 1,311 trials of external cephalic version. The Kleihauer-Betke test was positive in 67 (5.1%) before the procedure. Of the 1,244 women with a negative Kleihauer-Betke test before external cephalic version, 30 (2.4%) had a positive Kleihauer-Betke test after the procedure. Ten (0.8%) had an estimated fetomaternal hemorrhage greater than 1 mL, and one (0.08%) had an estimated fetomaternal hemorrhage greater than 30 mL. The risk of fetomaternal hemorrhage was not influenced by parity, gestational age, body mass index, number of attempts at version, placental location, or amniotic fluid index. The risk of detectable fetomaternal hemorrhage during external cephalic version was 2.4%, with fetomaternal hemorrhage more than 30 mL in less than 0.1% of cases. These data suggest that the performance of a Kleihauer-Betke test is unwarranted in uneventful external cephalic version and that in Rh-negative women, no further Rh immune globulin is necessary other than the routine 300-microgram dose at 28 weeks of gestation and postpartum.

    Full Text Available Dengue is a viral disease that is mediated by a mosquito, which causes morbidity and mortality. Viruses can increase vascular permeability which can lead to hemorrhagic diathesis or disseminated intravascular coagulation (DIC known as dengue hemorrhagic fever (DHF. In Indonesia, dengue hemorrhagic fever (DHF are caused by dengue virus infection which was found to be endemic accompanied by an explosion of extraordinary events that appear at various specified period. The diagnosis of dengue is determined based on the criteria of the World Health Organization (WHO, 1999, which are sudden high fever accompanied by a marked tendency to hemorrhage positive tourniquet test, petechiae, ecchymosis, purpura, mucosal hemorrhagic, hematemesis or melena and thrombocytopenia. The problem that still exists today is the mechanism of thrombocytopenia in patients with varying degrees of dengue involving levels of vWF (von Willebrand factor and prostaglandin I2 (PGI2 can not be explained. The mechanism of hemorrhagic in dengue virus infections acquired as a result of thrombocytopenia, platelet disfunction decreased coagulation factors, vasculopathy with endothelial injury and disseminated intravascular coagulation (DIC.

  4. Impaired Fracture Healing after Hemorrhagic Shock

    Philipp Lichte

    2015-01-01

    Full Text Available Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP of 35 mmHg for 90 minutes. Serum cytokines (IL-6, KC, MCP-1, and TNF-α were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

    The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pdefinition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Lennon, Christen J; Murry, Thomas; Sulica, Lucian

    2014-01-01

    Vocal fold hemorrhage is an acute phonotraumatic injury treated with voice rest; recurrence is a generally accepted indication for surgical intervention. This study aims to identify factors predictive of recurrence based on outcomes of a large clinical series. Retrospective cohort. Retrospective review of cases of vocal fold hemorrhage presenting to a university laryngology service. Demographic information was compiled. Videostroboscopic exams were evaluated for hemorrhage extent, presence of varix, mucosal lesion, and/or vocal fold paresis. Vocal fold hemorrhage recurrence was the main outcome measure. Follow-up telephone survey was used to complement clinical data. Forty-seven instances of vocal fold hemorrhage were evaluated (25M:22F; 32 professional voice users). Twelve of the 47 (26%) patients experienced recurrence. Only the presence of varix demonstrated significant association with recurrence (P = 0.0089) on multivariate logistic regression. Vocal fold hemorrhage recurred in approximately 26% of patients. Varix was a predictor of recurrence, with 48% of those with varix experiencing recurrence. Monitoring, behavioral management and/or surgical intervention may be indicated to treat patients with such characteristics. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    Computed tomography has been established as an indispensable tool in the detection of intracranial hemorrhages. Extra axial fluid collections are usually easily distinguished from intracerebral hemorrhages. However, hemorrhages in atypical locations, such as in falx and tentorial regions, can be difficult to diagnose with CT. The tentorial and falcial collection of subdural blood are rather unusual. Authors report here 84 cases of falcial and tentorial subdural hemorrhages with reference data that we have encountered in the last two years. The results were as follows; 1. In 589 cases of intracranial hemorrhage, the incidence of subdural hemorrhage was 372 cases (63.2%). 2. Among 372 cases with subdural hemorrhage, 84 cases (22.6%) had falcial and/or tentorial subdural hemorrhage. In 84 cases with falcial and/or tentorial subdural hemorrhage, there were 50 cases (13.4%) of falcial subdural hemorrhages, 21 cases (5.7%) of tentorial subdural hemorrhage and 13 cases (3.5%) of combined falcial and tentorial subdural hemorrhage. 3. The location of falcial subdural hemorrhage was anterior in 30 cases (60%), posterior in 15 cases (30%) and middle in 5 cases (10%). 4. The location of tentorial subdural hemorrhage was petrous edge in 7 cases (33.3%), occipital attachment in 6 cases (28.6%), tentorial hiatus in 5 cases (23.8%), and diffuse in 3 cases (14.3%). 5. In 13 cases showing combined falcial and tentorial subdural hemorrhage, there was 3 cases (23.1%) of posterior falx and tentorial hiatus, 2 cases (15.4%) of anterior falx and petrous edge, 2 cases of anterior falx and tentorial hiatus, 2 cases of posterior falx and petrous edge, 2 cases of posterior falx and occipital attachment, 1 case (7.7%) of posterior falx and diffuse, and 1 case of posterior, middle falx and diffuse. 6. In the cases with falcial and/or tentorial subdural hemorrhage, the incidence of associated intracranial hemorrhage were intracrania subdural hemorrhage in 40 cases (47.6%), hemorrhagic brain

  8. Hemorrhagic Aspects of Gaucher Disease

    Hanna Rsenbaum

    2014-10-01

    Full Text Available Gaucher disease (GD is an inherited lysosomal disorder, originating from deficient activity of the lysosomal enzyme glucocerebrosidase (GCase. Normally, GCase hydrolyzes glucocerebroside (GC to glucose and ceramide; however, impaired activity of this enzyme leads to the accumulation of GC in macrophages, termed “Gaucher cells.” Gaucher disease is associated with hepatosplenomegaly, cytopenias, skeletal complications and in some forms involves the central nervous system. Coagulation abnormalities are common among GD patients due to impaired production and chronic consumption of coagulation factors. Bleeding phenomena are variable (as are other symptoms of GD and include mucosal and surgical hemorrhages. Four main etiological factors account for the hemostatic defect in GD: thrombocytopenia, abnormal platelet function, reduced production of coagulation factors, and activation of fibrinolysis. Thrombocytopenia relates not only to hypersplenism and decreased megakaryopoiesis by the infiltrated bone marrow but also to immune thrombocytopenia. Autoimmunity, especially the induction of platelet antibody production, might cause persistent thrombocytopenia. Enzyme replacement therapy reverses only part of the impaired coagulation system in Gaucher disease. Other therapeutic and supportive measures should be considered to prevent and/or treat bleeding in GD. Gaucher patients should be evaluated routinely for coagulation abnormalities especially prior to surgery and dental and obstetric procedures.

    Adrenal cysts are usually asymptomatic; they are usually identified occasionally during ultrasound or C.T. scans (incidentaloma). Among adrenal cysts the most common types are epithelial cysts and pseudocysts. Intracystic haemorrhage is one of the possible complications of adrenal pseudocysts. We report a case of a young woman with right superior abdominal pain, fever and acute anemia. A C.T. scan showed a 10 cm. mass between the liver and the right kidney. To be sure of the nature of this mass also M.R., urography and C.T.-guided biopsy were carried out. This latter only let us make the final diagnosis of hemorrhagic adrenal pseudocyst. Thereafter, a laparotomic right adrenalectomy was performed, with full recovery of the patient. Adrenal cysts may cause differential diagnostic problems with masses of contiguous organs like kidney, liver and gallbladder. For this reason, ultrasound and C.T. scans may not be sufficient and must be completed by M.R., urography and/or C.T.-guided biopsy. Intracystic hamorrhage, spontaneous or post-traumatic, may cause to the patient acute anemia which, as soon as the diagnosis is confirmed, indicates surgery. The operation usually is a laparotomic adrenalectomy, since the laparoscopic approach is not sufficient to control large masses with active bleeding inside.

  10. GWAS analysis using interspecific backcross progenies reveals superior blue catfish alleles responsible for strong resistance against enteric septicemia of catfish.

    Infectious diseases pose significant threats to the catfish industry. Enteric septicemia of catfish (ESC) caused by Edwardsiella ictaluri is the most devastating disease for catfish aquaculture, causing huge economic losses annually. Channel catfish and blue catfish exhibit great contrast in resistance against ESC, with channel catfish being highly susceptible and blue catfish being highly resistant. As such, the interspecific backcross progenies provide an ideal system for the identification of quantitative trait locus (QTL). We previously reported one significant QTL on linkage group (LG) 1 using the third-generation backcrosses, but the number of founders used to make the second- and third-generation backcross progenies was very small. Although the third-generation backcross progenies provided a greater power for fine mapping than the first-generation backcrosses, some major QTL for disease resistance may have been missing due to the small numbers of founders used to produce the higher generation backcrosses. In this study, we performed a genome-wide association study using first-generation backcrosses with the catfish 690 K SNP arrays to identify additional ESC disease resistance QTL, especially those at the species level. Two genomic regions on LG1 and LG23 were determined to be significantly associated with ESC resistance as revealed by a mixed linear model and family-based association test. Examination of the resistance alleles indicated their origin from blue catfish, indicating that at least two major disease resistance loci exist among blue catfish populations. Upon further validation, markers linked with major ESC disease resistance QTL should be useful for marker-assisted introgression, allowing development of highly ESC resistant breeds of catfish.

  11. How Hemorrhage Control Became Common Sense.

    Hawk, Alan James

    2018-02-27

    Just over 200 years ago, surgeons were puzzled that the use of the tourniquet to control hemorrhage as common sense during surgery was a relatively recent development. Within the last 20 years, much progress has been made to controlling hemorrhage in the prehospital context. Then, as now, it was surprising that progress on something that appeared obvious had occurred only recently, begging the question how controlling blood loss was common sense in a surgical context, but not for emergency treatment. Paper is a historical survey of the evolution of the medical understanding of hemorrhage along with technological response. The danger of blood loss had historically been consistently underestimated as physicians looked at other explanations for symptoms of how the human body responded to trauma. As the danger from hemorrhage became apparent, even obvious, responsibility for hemorrhage control was delegated down from the surgeon to the paramedic and eventually to individual service members and civilian bystanders with training to "Stop the Bleed." Hippocratic medicine assumed that blood diffused centrifugally into periphery through arteries. William Harvey's observation in 1615 that blood ran through a closed circulatory system gradually transformed conventional wisdom about blood loss, leading to the development of the tourniquet about a century later by Jean-Louis Petit, which made amputation of limbs survivable. However, physicians were cautious about their application during the First World War over concerns over effects on patient recovery. Hemorrhage had generally been seen as symptom to be managed until the patient would be seen by a surgeon who would stop the bleeding. More thorough collection and analysis of data related to case histories of soldiers wounded during the Vietnam Conflict transformed how surgeons understood the importance to hemorrhage leading to development of the doctrine of Tactical Combat Casualty Care in the late 1990's. economic

    1998-01-01

    The purpose of this study is to evaluate the signal characteristics of intracranial hemorrhage, as seen on fluid attenuated inversion recovery (FLAIR) MR imaging according to various stages, and to compare FLAIR imaging with spin-echo T1- and T2-weighted MR imaging. We retrospectively evaluated fast FLAIR images along with spin-echo T1- and T2 weighted MR images of 32 lesions in 25 patients (12 males and 14 females, aged 3 - 84 yrs) with intracranial hemorrhagic lesions. For imaging, 1.5 T unit was used, and the nature of the lesions was found to be as follows : intracranial hemorrhage (n=15); tumor (n=9); infarction (n=4); arteriovenous malformation (n=3); and arachnoid cyst with hemorrhage (n=1). On the basis of spin-echo MR imaging, lesions were classified as acute, early subacute, late subacute, early chronic, or late chronic stage. The signal characteristics of intracranial hemorrhage were analysed in accordance with each staging, as seen on MR FLAIR imaging, and compared to the staging seen on spin-echo T1- and T-2 weighted MR imaging. The signal intensity of intracranial hemorrhage, as seen on FLAIR imaging, was not characteristic; it was similar to that of T2WI during the acute and subacute stages, and similiar to that of T1WI during the chronic stage. When used together with spin-echo T1- and T2-weighted MR imaging, however, FLAIR imaging may be useful for the classification of chronic intracranial hemorrhage as either early or late stage.

    Makishita, Hideo; Miyasaka, Motomaro; Tanizaki, Yoshio; Yanagisawa, Nobuo; Sugishita, Morihiro.

    1984-01-01

    We reported 7 patients with left thalamic hemorrhage in the chronic stage (from 1.5 months to 4.5 months), and described language disorders examined by Western Aphasia Battery (WAB) and measured cerebral blood flow by single photon emission CT. Examination of language by WAB revealed 4 aphasics out of 7 cases, and 3 patients had no language deficit. The patient with Wernicke's aphasia showed low density area only in the left posterior thalamus in X-ray CT, and revealed severe low blood flow area extending to left temporal lobe in emission CT. In the case with transcortical sensory aphasia, although X-ray CT showed no obvious low density area, emission CT revealed moderate low flow area in watershed area that involved the territory between posterior cerebral and middle cerebral arteries in the left temporooccipital region in addition to low blood flow at the left thalamus. In one of the two patients classified as anomic aphasia, whose score of repetition (8.4) was higher than that of comprehension (7.4), emission CT showed slight low flow area at the temporo-occipital region similarly as the case with transcortical sensory aphasia. In another case with anomic aphasia, scored 9 on both fluensy and comprehension subtests and 10 on repetition, there was wide low density area all over the left thalamus and midline shift to the right in X-ray CT, and emission CT showed severe low blood flow in the same region spreading widely toward the cerebral surface. On the other hand, in all of the 3 patients without aphasia, emission CT showed low flow region restricted to the left thalamus. (J.P.N.)

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient

    Ninety-two percent of 100 patients with putaminal hemorrhage were hypertensive. Of the eight normotensive patients, seven were substance abusers or had bilateral putaminal hemorrhages. The one other normotensive patient was less than 40 years old. The 100 hemorrhages had the following locations: 1. Medial putaminal (17 cases; six were normotensive and less than 40 years old and five were substance abusers); 2. lateral putaminal extending through the external capsule (eleven cases); 3. putaminal-capsular and subcortical white matter (32 cases); 4. putaminal cerebral hemispheric (19 cases); 5. putaminal-thalamic (19 cases); 6. bilateral (two cases). A disproportionate number of black patients suffered hematoma extension to the cerebral hemispheres or thalamus (46%) compared to Caucasians (23%). Overall mortality was 20% (17 blacks and three Caucasians) and occurred in patients with hematoma extension to the thalamus or cerebral hemispheres. Contrast-enhanced CT was performed in all 100 patients and provided no additional diagnostic yield. This indicates limited use for enhanced CT in hypertensive patients with putaminal hemorrhage who have a characteristic appearance of the acute hemorrhage on the nonenhanced CT. (orig.)

    2011-01-01

    We designed a new endoscopic surgical procedure for putaminal hemorrhage (freehand technique) and evaluated its effectiveness and safety in patients with putaminal hemorrhage. Computed tomography (CT) data sets from 40 healthy patients were used. The CT data were transformed into three-dimensional images using AZE VirtualPlace Plus. The nasion and external auditory foramen were the intraoperative reference points. The median point from medial of the globus pallidus to the insula was the target point. The location of the burr hole point was 80-125 mm above and 27.5 mm lateral to the nasion, and the direction was parallel to the midline and a line drawn from the burr hole to the ipsilateral external auditory foramen. This point was used for 15 patients with putaminal hemorrhage. In all cases, only one puncture was required, and there were no complications. The median surgical time was 91.7 minutes, and the median hematoma removal rate was 95.9%. No recurrent bleeding or operative complications occurred. The freehand technique is a simple and safe technique for patients with putaminal hemorrhage. We believe that this technique of endoscopic hematoma evacuation may provide a less-invasive method for treating patients with putaminal hemorrhage. (author)

    A 71-year old patient suffering from untreated non-insulin-dependent diabetes presented anti-inflammatory drug-resistant lumbalgia with referred inguinal pain either on the right or left side, corresponding to the first signs of septicemia due to staphylococcus aureus, with urinary onset. Despite specific antibiotic treatment, pulmonary, cardiac and neurological complications followed. Simultaneous investigations by MRI and bone scintigraphy performed in the remitting patient showed multiple septic metastatic localization in the soft tissues and bones. It was hence necessary to pursue the antibiotic therapy to avoid relapses. (author)

  19. The first imported human case of Yersinia pseudotuberculosis serotype O1 septicemia presents with acute appendicitis-like syndrome in Taiwan

    2014-09-01

    Full Text Available Human nonplague yersiniosis occurs more commonly in temperate regions than in tropical or subtropical regions. In Taiwan, which is located in a subtropical region of Southeast Asia, only environmental isolates and human infection of Yersinia enterocolitica were reported, but a human case of Y. pseudotuberculosis infection had not been identified. We report the first person with Y. pseudotuberculosis serotype O1 septicemia who presented with acute appendicitis-like syndrome and who was probably contracted the infection via ingestion of raw foods in a barbecue restaurant in Japan.

    1983-01-01

    Thirty-two of 290 neonates admitted to the Perinatal Intensive Care Unit, Toho University Medical School, were examined by CT scan because of tentative clinical diagnosis of intracranial hemorrhage. CT scanner employed in this study was TCT-60 A from the Toshiba The Electric Co., Ltd. Fourteen cases (44%) were confirmed by the CT scan to have intracranial hemorrhage. Four cases had hemorrhage in the ventricle, while the remaining ten cases had subarachnoid hemorrhage. Subdural hemorrhage was not revealed in our series. Three of the four cases with intraventricular hemorrhage showed a typical subependymal germinal matrix hemorrhage. The prognosis of intraventricular hemorrhage in neonates seemed to be poor; two of the four cases died within a week. Their body weight at birth was apparently under the standard, and their Apgar score was 3 points. The subarachnoid hemorrhage was the main type of intracranial neonatal hemorrhages. In our series, it was constituted approximately 70% of the intracranial hemorrhages. The CT images of the subarachnoid hemorrhage in neonate were greatly different from those in adults. An irregular, wide high-density area around the falxtentorial junction was characteristic of the CT in many neonatal subarachnoid hemorrhages. In severe subarachnoid hemorrhages, a characteristic Y-shaped, high-density figure was demonstrated. In cases of subarachnoid hemorrhage from the deep venous system, high-density spreading immediately ventral to the falx-tentrium junction was demonstrated. These high-density areas due to blood in the subarachnoid space rapidly disappeared with the lapse of time. On the other hand, high-density areas in cerebral cisterns and/or fissures were rarely demonstrated in neonatal subarachnoid hemorrhages. The prognosis of subarachnoid hemorrhage in neonates was fairly good in the sense of life and cerebral functions. (author)

  1. Cerebral microbleeds and intracerebral hemorrhages in patients on maintenance hemodialysis

    Watanabe, Akira

    2006-01-01

    Cerebrovascular diseases are important causes of death in patients on maintenance hemodialysis. Recently, it has become clear that the presence of cerebral microbleeds (MBs) on T2 * -weighted magnetic resonance imaging (MRI) is closely related to intracerebral hemorrhages. This study investigated the incidence of MBs in chronic dialysis patients and prospective hemorrhagic complications of chronic dialysis patients with old intracerebral hemorrhages. Eighty patients (34 males, 46 females) with chronic renal failure, whose mean age was 62.9±11.4 years, were examined by MRI. The mean duration of hemodialysis was 7.8±6.3 years. MBs were found in 28 patients (35%) by T2 * -weighted MRI. Old intracerebral hemorrhages were seen in seven of the patients, and MBs were found in five (71%) of these seven patients. The frequency of old intracerebral hemorrhages was significantly higher in patients with MBs than in those without (p=0.048), and the numbers of MBs were significantly larger in patients with old intracerebral hemorrhages than in those without (p=0.0065). Three of the seven patients with old intracerebral hemorrhages had new hemorrhagic complications (two intracerebral hemorrhages and one cerebral microbleed) within a year. These intracerebral hemorrhages occurred in areas without MBs on the first T2 * -weighted MRI. T2 * -weighted MRI is useful for the detection of MBs, which may be a predictor of intracerebral hemorrhage. When a patient has a large number of MBs and old intracerebral hemorrhages, the risk of intracerebral hemorrhage undoubtedly increases. (author)

    2000-01-01

    Objective: To study the angiographic manifestations and arterial embolizatin for traumatic renal hemorrhage when conservative treatment had failed. methods: 5 cases, all male, ranging in age from 12-29 years. All cases had history of injury. the main symptoms included severe abdominal pain, hematuria or coffee colored urine, rapid heart rate, hypotension. 3 suffered hemorrhagic shock. All cases underwent angiographic exam and the diagnosis was confirmed. Embolization materials were mainly self-blood clot and gelfoam. Results: Symptoms in all cases subsided quickly after embolization. Blood pressure recovered to normal within 12 hours; Hematuresis and abdominal pain disappeared or reduced in 1-2 days. One month later, intravenous urographic exam revealed recovered function of the injured kidneys. Conclusion: Renal arterial embolization in treating traumatic renal hemorrhage can control the bleeding while preserving the injured kidneys

    hemorrhagic transformation is a threatening ischemic stroke complication. Frequency of hemorrhagic transformation differs greatly among studies, and its risk factors have been usually studied in patients with anterior ischemic stroke who received thrombolytic therapy. We evaluated, in a hospital-based series of patients with posterior ischemic stroke not treated with thrombolysis, frequency and risk factors of hemorrhagic transformation. Patients with posterior circulation stroke were seen in our Department during the period January 2004 to December 2009. Demographic and clinical information were collected. We estimated risk for spontaneous hemorrhagic transformation by means of uni- and multivariate logistic regression analyses. 119 consecutive patients were included (73 males, 61.3%). Hemorrhagic transformation was observed in 7 patients (5.9%). Only clinical worsening was significantly associated with hemorrhagic transformation (OR 6.8, 95% CI 1.3-34.5). Our findings indicate that patients with posterior have a low risk of spontaneous hemorrhagic transformation, suggesting that these patients might have greater advantage from intravenous thrombolysis.

  4. Alterations of Mg2+ After Hemorrhagic Shock.

    Lee, Mun-Young; Yang, Dong Kwon; Kim, Shang-Jin

    2017-11-01

    Hemorrhagic shock is generally characterized by hemodynamic instability with cellular hypoxia and diminishing cellular function, resulting from an imbalance between systemic oxygen delivery and consumption and redistribution of fluid and electrolytes. Magnesium (Mg) is the fourth most abundant cation overall and second most abundant intracellular cation in the body and an essential cofactor for the energy production and cellular metabolism. Data for blood total Mg (tMg; free-ionized, protein-bound, and anion-bound forms) and free Mg 2+ levels after a traumatic injury are inconsistent and only limited information is available on hemorrhagic effects on free Mg 2+ as the physiologically active form. The aim of this study was to determine changes in blood Mg 2+ and tMg after hemorrhage in rats identifying mechanism and origin of the changes in blood Mg 2+ . Hemorrhagic shock produced significant increases in blood Mg 2+ , plasma tMg, Na + , K + , Cl - , anion gap, partial pressures of oxygen, glucose, and blood urea nitrogen but significant decreases in RBC tMg, blood Ca 2+ , HCO 3 - , pH, partial pressures of carbon dioxide, hematocrit, hemoglobin, total cholesterol, and plasma/RBC ATP. During hemorrhagic shock, K + , anion gap, and BUN showed significant positive correlations with changes in blood Mg 2+ level, while Ca 2+ , pH, and T-CHO correlated to Mg 2+ in a negative manner. In conclusion, hemorrhagic shock induced an increase in both blood-free Mg 2+ and tMg, resulted from Mg 2+ efflux from metabolic damaged cell with acidosis and ATP depletion.

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

    2012-01-01

    Automated hemorrhage detection and segmentation in traumatic pelvic injuries is vital for fast and accurate treatment decision making. Hemorrhage is the main cause of deaths in patients within first 24 hours after the injury. It is very time consuming for physicians to analyze all Computed Tomography (CT) images manually. As time is crucial in emergence medicine, analyzing medical images manually delays the decision-making process. Automated hemorrhage detection and segmentation can significantly help physicians to analyze these images and make fast and accurate decisions. Hemorrhage segmentation is a crucial step in the accurate diagnosis and treatment decision-making process. This paper presents a novel rule-based hemorrhage segmentation technique that utilizes pelvic anatomical information to segment hemorrhage accurately. An evaluation measure is used to quantify the accuracy of hemorrhage segmentation. The results show that the proposed method is able to segment hemorrhage very well, and the results are promising.

    Between 1980 and 1994, 423 patients with esophageal cancer were given curative r[iation therapy. Of these patients, 31 died of massive hemorrhage and were used as the subjects of analysis in this study. The incidence of massive hemorrhage in all patients was 7% (31/423). In the 31 patients who died of massive hemorrhage, 27 h[ local tumors and two h[ no tumors at hemorrhage (two unknown cases). The mean time interval from the start of r[iation to hemorrhage was 9.2 months. In 9 autopsy cases the origin of hemorrhage was a tear of the aorta in 5 cases, necrotic local tumor in 3 cases and esophageal ulcer in 1 case. The positive risk factors for this complication seemed to be excess total dose, infection, metallic stent, and tracheoesophageal fistula. Chest pain or sentinel hemorrhage proceeding to massive hemorrhage was observed in about half of the patients. (orig.)

    2013-01-01

    The adrenal hemorrhage is a relatively rare event in newborns but must be considered in the presence of a persistent unexplained jaundice, especially in presence of predisposing factors. Serial ultrasonography is the modality of choice for initial diagnosis and follow-up of neonatal adrenal hemorrhage. We report two cases of neonatal adrenal hemorrhage presenting with persistent jaundice. The causes of the neonatal adrenal hemorrhages were a difficult vaginal delivery in macrosomic infant and a neonatal infection.

  12. Hemorrhage-adjusted iron requirements, hematinics and hepcidin define hereditary hemorrhagic telangiectasia as a model of hemorrhagic iron deficiency.

    Helen Finnamore

    Full Text Available Iron deficiency anemia remains a major global health problem. Higher iron demands provide the potential for a targeted preventative approach before anemia develops. The primary study objective was to develop and validate a metric that stratifies recommended dietary iron intake to compensate for patient-specific non-menstrual hemorrhagic losses. The secondary objective was to examine whether iron deficiency can be attributed to under-replacement of epistaxis (nosebleed hemorrhagic iron losses in hereditary hemorrhagic telangiectasia (HHT.The hemorrhage adjusted iron requirement (HAIR sums the recommended dietary allowance, and iron required to replace additional quantified hemorrhagic losses, based on the pre-menopausal increment to compensate for menstrual losses (formula provided. In a study population of 50 HHT patients completing concurrent dietary and nosebleed questionnaires, 43/50 (86% met their recommended dietary allowance, but only 10/50 (20% met their HAIR. Higher HAIR was a powerful predictor of lower hemoglobin (p = 0.009, lower mean corpuscular hemoglobin content (p<0.001, lower log-transformed serum iron (p = 0.009, and higher log-transformed red cell distribution width (p<0.001.

Iron supplement use increased the proportion of individuals meeting their HAIR, and blunted associations between HAIR and hematinic indices. Once adjusted for supplement use however, reciprocal relationships between HAIR and hemoglobin/serum iron persisted. Of 568 individuals using iron tablets, most reported problems completing the course. For patients with hereditary hemorrhagic telangiectasia, persistent anemia was reported three-times more frequently if iron tablets caused diarrhea or needed to be stopped.HAIR values, providing an indication of

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

  16. [Selective embolization to treat obstetric hemorrhage].

    Ferrer Puchol, M D; Lanciego, C; Esteban, E; Ciampi, J J; Edo, M A; Ferragud, S

    2014-01-01

    To describe cases of obstetric hemorrhage that have called for selective intra-arterial embolization and the different embolization techniques used. To assess the clinical outcomes and postprocedural fertility. We studied 27 women with obstetric hemorrhage. In 24 patients, embolization was performed by catheterizing both uterine arteries and in 2 patients only one uterine artery was catheterized (pseudoaneurysm). The materials used for embolization consisted of Spongostan in 17/27, particles in 9/27, and coils in 1/27. Clinical follow-up included an analysis of early and late complications and of postprocedural fertility. Hemorrhage was classified as primary (25/27) or secondary (2/27). The cause of bleeding was vaginal delivery (20), cesarean sections (5), abortion (1), and cervical ectopic pregnancy (1). The initial technical success rate was 100% and the clinical success rate was 92.6% (25 of the 27 patients). Bleeding ceased and the outcome was satisfactory in 25 patients. During clinical follow-up ranging from one to seven years, 23 patients had normal menstruation and 6 patients completed 7 full-term pregnancies. Intra-arterial embolization for obstetric hemorrhage leads to good outcomes and few complications and it preserves fertility. Copyright © 2011 SERAM. Published by Elsevier Espana.

    Durrani, A.B.; Shaikh, M.; Khan, Z.

    2007-01-01

    To observe the pattern and mortality of Congo-Crimean Hemorrhagic Fever (CCHF) in Balochistan. Two hundred and twenty-six febrile patients with bleeding of sudden onset, with initial signs and symptoms including headache, high fever, back pain, joint pain, stomach pain, vomiting, red eyes, flushed face, red throat and petechiae on the palate of both sexes were screened for CCHF over a period of 10 years. Clinical criteria for initial diagnosis directed the subsequent diagnostic work-up. The ages of these patients ranged from 7 years to 74 years. Sixty-three percent of these patients were positive for CCHF. Males were 68% of the total patients. Over the years, CCHF showed a gradual increase ranging from 43% to 80%. Total mortality was 15%, all being secondary cases. Death was not observed in primary CCHF cases. In this study, suspicion of viral hemorrhagic fever was raised in 62% cases at the time of admission and the patients were immediately isolated, noninvasive procedures were instigated and barrier nursing was implemented. None of the family and hospital staff members who had close contact with the patient became ill, while those who were not suspected initially (38%) infected the health care workers and the family members. Although CCHF is rare, this study stresses the need for proper health facilities in Pakistan and to include VHF (viral hemorrhagic fevers) in the differential diagnosis of unexplained fever with hemorrhagic tendencies of sudden onset.

  4. Unraveling the distinctive features of hemorrhagic and non-hemorrhagic snake venom metalloproteinases using molecular simulations

    de Souza, Raoni Almeida; Díaz, Natalia; Nagem, Ronaldo Alves Pinto; Ferreira, Rafaela Salgado; Suárez, Dimas

    2016-01-01

    Snake venom metalloproteinases are important toxins that play fundamental roles during envenomation. They share a structurally similar catalytic domain, but with diverse hemorrhagic capabilities. To understand the structural basis for this difference, we build and compare two dynamical models, one for the hemorrhagic atroxlysin-I from Bothrops atrox and the other for the non-hemorraghic leucurolysin-a from Bothrops leucurus. The analysis of the extended molecular dynamics simulations shows some changes in the local structure, flexibility and surface determinants that can contribute to explain the different hemorrhagic activity of the two enzymes. In agreement with previous results, the long Ω-loop (from residue 149 to 177) has a larger mobility in the hemorrhagic protein. In addition, we find some potentially-relevant differences at the base of the S1' pocket, what may be interesting for the structure-based design of new anti-venom agents. However, the sharpest differences in the computational models of atroxlysin-I and leucurolysin-a are observed in the surface electrostatic potential around the active site region, suggesting thus that the hemorrhagic versus non-hemorrhagic activity is probably determined by protein surface determinants.

    Objective: To evaluate the therapeutic efficacy of uterine arterial embolization (UAE) for intractable uterine hemorrhage. Methods: 16 patients with intractable uterine hemorrhage underwent bilateral UAE after failed conventional conservative treatment. Results: Uterine hemorrhage ceased within 12 hours in 15 patients (93.8%) after bilateral super-selective UAE. Internal iliac artery embolization was performed on one patient (6.2%) and hysterectomy was eventually carried out because of recurrent hemorrhage. Conclusion: UAE is a rapid and effective treatment method obviating hysterectomy for intractable uterine hemorrhage. (authors)

  6. Functional recovery and surgical indication in putaminal hemorrhage

    Fujitsu, Kazuhiko

    1983-01-01

    Forty-one cases of varied sized putaminal hemorrhage were classified into 4 types according to the precise localization on CT (Fig. 1). All cases with large-sized hemorrhage (more than 4-5 cm in the actual diameter) were treated surgically regardless of their types in CT classification. ADL was assessed 6 months after the onset in all 41 cases, and in 17 of these Standard Language Test of Aphasia (SLTA) was also given 1 to 3 months after the dominant hemispheric hemorrhage. Type I hemorrhage usually showed excellent ADL independently of the size of the hemorrhage (Table 3). In type II hemorrhage, the ADL is determined by the extent of the lesion and tended to deteriorate as the size of the hemorrhage increased (Table 4). Type III hemorrhage resumed less favorable ADL than the type II did (Table 5), and there was scarcely any functional recovery in Type IV hemorrhage (Table 6). On SLTA, impairment of the speaking ability was the prominant feature when the hemorrhage was primarily located in the anterior portion of the insula, while the hearing ability was more markedly impaired in the posteriorly located lesion. These location-dependent specific patterns of impairment on SLTA are schematically presented in Fig. 12. From these results described above, the author's CT classification is considered to be very useful not only in forecasting the prospects of functional recovery, but in determining the surgical indication in putaminal hemorrhage.

    The purpose of this study is to identify the characteristics of brain perfusion measured by arterial spin-labeling magnetic resonance imaging (ASL-MRI) in cerebral hemorrhages. Brain blood flow values (CBF-ASL values) for cerebral and cerebellar hemispheres and segmented cerebral regions were measured by ASL-MRI in 19 putaminal hemorrhage patients and 20 thalamic hemorrhage patients in acute or subacute stages. We assessed the lateralities of CBF-ASL values and the relationships between CBF-ASL values and other imaging findings and clinical manifestations. Both the 19 putaminal hemorrhage patients and the 20 thalamic hemorrhage patients had significantly low CBF-ASL values of the contralateral cerebellum in subacute stage, suggesting that ASL-MRI might delineate crossed cerebellar diaschisis (CCD). Ipsilateral low CBF-ASL values were observed in frontal lobes and thalami with a putaminal hemorrhage and lentiform nuclei, temporal lobes, and parietal lobes with a thalamic hemorrhage, suggesting that ASL-MRI showed the ipsilateral cerebral diaschisis (ICD). In the putaminal hemorrhage patients, the hematoma volume negatively affected both the bilateral cerebellar and cerebral hemispheric CBF-ASL values. In the thalamic hemorrhage patients, a concomitant intraventricular hemorrhage caused low cerebral hemispheric CBF-ASL values. The use of ASL-MRI is sensitive to the perfusion abnormalities and could thus be helpful to estimate functional abnormalities in cerebral hemorrhage patients. (orig.)

  9. CLINICAL AND MORPHOLOGICAL CLASSIFICATION OF CEREBRAL INTRAVENTRICULAR HEMORRHAGES

    V. V. Vlasyuk

    2013-01-01

    Full Text Available Inconsistency of the current classification of cerebral intraventricular hemorrhages is discussed in the article. The author explains divergence of including of the subependymal (1st stage and intracerebral (4th stage hemorrhages into this classification. A new classification of cerebral intraventricular hemorrhages including their origin, phases and stages is offered. The most common origin of intraventricular hemorrhages is subependymal hemorrhage (82,2%. Two phases of hemorrhage were distinguished: bleeding phase and resorption phase. Stages of intraventricular hemorrhages reflecting the blood movement after the onset of bleeding are the following: 1 — infill of the up to ½ of the lateral ventricles without their enlargement; 2 — infill of more than ½ of the lateral ventricles with their enlargement; 3 — infill of the IV ventricle, of the cerebellomedullary cistern and its dislocation into the subarachnoid space of the cerebellum, pons varolii, medulla oblongata and spinal cord.

  11. Pathogenesis of lober intracerebral hemorrhage related to cerebral amyloid angiopathy

    2010-01-01

    Cerebral amyloid angiopathy (CAA) is an important cause of lober intracerebral hemorrhage in the elderly. Although leptomeningeal and cortical arteries with the deposition of the amyloid β-protein (Aβ) have been thought to rupture in CAA, the pathogenesis of CAA-related hemorrhage still remains obscure. We studied 10 cases of CAA according to the Boston criteria from April 2006 to July 2009 in Omaezaki Municipal Hospital. Based on clinical data, we examined the primary site of hemorrhage and hypothesized the mechanisms of bleeding. Intracerebral hematoma evacuation was performed to alleviate neurological deteriolation in 2 patients and to make diagnosis in 3 patients. The surgical specimens were pathologically examined. The characteristic MR images of CAA related hemorrhage were characterized by microbleeds, superficial siderosis, subpial or subarachnoid hemorrhage, subcortical hemorrhage and lober intracerebral hemorrhage. Chronological images obtained in 1 patient revealed that lober intracerebral hemorrhage developed from microbleed with subpial hemorrhage without subarachnoid hemorrhage in one side of the cortex in the affected facing cerebral sulci. Operative findings showed subpial and subarachnoid hemorrhages around the cortical veins on the affected cerebral sulci in all cases. Abnormal fragile vessels existed in one side of the cortex of the affected sulci but not in the other side of the cortex. Complete hamatoma evacuation was performed in 4 cases. The surgical specimens of the hematoma and the adjacent brain parenchyma were pathologically examined by tissue staining with hematoxylin-eosin and Congo red. Many vessels in subpial, subcortical and subarachnoid space along the cerebral sulci were deposited with Aβ. From these findings, we speculated that the primary hemorrhage related to CAA occurred from the cortical arteries with Aβ deposition in the subpial space along the cerebral sulci and formed a lober intracerebral hematoma.

  12. Intracranial drug delivery for subarachnoid hemorrhage.

    Macdonald, Robert Loch; Leung, Ming; Tice, Tom

    2012-01-01

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

  13. Neurogenic stunned myocardium following hemorrhagic cerebral contusion

    Deleu, D.; Miyares, F.; Kettern, M.; Kumar, S.; Hassens, Y.; Salim, K.

    2007-01-01

    Neurogenic stunned myocardium NSM is a well-known complication of subarachnoidal hemorrhage, but has been reported rarely in association with other central nervous system disorders. A case of NSM is described in a patient with hemorrhagic brain contusion associated with cerebral edema. An 18-year-old man was admitted with severe cranial trauma following a car roll-over. Six days after admission, he developed findings suggestive for NSM. The troponin T and creatine kinase-MB level were elevated and echocardiogram showed apical and inferoposterior hypokinesis and diffuse left ventricular akinesis with severely reduced ejection fraction 18%. Invasive measurements confirmed low cardiac output. His cardiac function resolved completely within 6 days after decompressive craniotomy. This case supports the presumed unifying role of the increased intracranial pressure, probably triggering a vigorous sympathetic outflow hyperactivity leading to NSM. (author)

  14. Infection control during filoviral hemorrhagic fever outbreaks

    N Raabe Vanessa

    2012-01-01

    Full Text Available Breaking the human-to-human transmission cycle remains the cornerstone of infection control during filoviral (Ebola and Marburg hemorrhagic fever outbreaks. This requires effective identification and isolation of cases, timely contact tracing and monitoring, proper usage of barrier personal protection gear by health workers, and safely conducted burials. Solely implementing these measures is insufficient for infection control; control efforts must be culturally sensitive and conducted in a transparent manner to promote the necessary trust between the community and infection control team in order to succeed. This article provides a review of the literature on infection control during filoviral hemorrhagic fever outbreaks focusing on outbreaks in a developing setting and lessons learned from previous outbreaks. The primary search database used to review the literature was PUBMED, the National Library of Medicine website.

    2016-01-01

    Hemorrhagic stroke is a common and severe neurological disorder and is associated with high rates of mortality and morbidity, especially for intracerebral hemorrhage (ICH). Increasing evidence demonstrates that oxidative stress responses participate in the pathophysiological processes of secondary brain injury (SBI) following ICH. The mechanisms involved in interoperable systems include endoplasmic reticulum (ER) stress, neuronal apoptosis and necrosis, inflammation, and autophagy. In this review, we summarized some promising advances in the field of oxidative stress and ICH, including contained animal and human investigations. We also discussed the role of oxidative stress, systemic oxidative stress responses, and some research of potential therapeutic options aimed at reducing oxidative stress to protect the neuronal function after ICH, focusing on the challenges of translation between preclinical and clinical studies, and potential post-ICH antioxidative therapeutic approaches.

    Recently, CT-guided stereotactic aspiration has been attempted as a useful method for hypertensive intracerebral hemorrhage. Since the CT scanner was introduced in our clinic, we have experienced 55 cases with hypertensive pontine hemorrhage. We carried out stereotactic aspiration in nine cases consisting of four men and five women, ranging in age from 34 to 66 years. Operation was performed between 4 and 22 days after the hemorrhage (mean: 7.7 days). On the other hand, 46 cases were conservatively treated. They consisted of 31 men and 15 women, aged from 31 to 79 years, with a mean age of 55.5 years. The purpose of this study is to review the outcome at three months after the onset, and then to evaluate the clinical value of this method for hypertensive pontine hemorrhage. We have analyzed the outcome from the viewpoint of consciousness level, CT classification, and maximum transverse hematoma diameter on CT scan. In the present study, there was a statistically significant correlation between consciousness level and outcome in the conservative group. The outcome in the operated-on group tended to be superior to that in the conservatively treated group. Particularly, in cases of Japan Coma Scale 10 to 100, functionally favorable effects were considered to be obtained by stereotactic aspiration. According to CT classification, operation was considered to have exerted functionally favorable effects on unilateral basis tegmentum type and bilateral tegmentum type. The conservatively treated group showed a statistically significant correlation between maximum transverse hematoma diameter and outcome. A favorable prognosis was considered to be induced by operation in cases of 22 to 28 mm in maximum transverse hematoma diameter. (author)

    Baking soda is a readily available household product composed of sodium bicarbonate. It can be used as a home remedy to treat dyspepsia. If used in excessive amounts, baking soda has the potential to cause a variety of serious metabolic abnormalities. We believe this is the first reported case of hemorrhagic encephalopathy induced by baking soda ingestion. Healthcare providers should be aware of the dangers of baking soda misuse and the associated adverse effects.

  2. A study on hypertensive intracerebral hemorrhage

    Miura, Naohisa

    1982-01-01

    We studied 235 patients with hypertensive intracerebral hemorrhage by CT for about five years. An acute intracerebral hematoma is characterized by sharply delineated high density area. Repeated CT examinations demonstrate reduction in size of the high density hematoma after intervals of 20 - 40 days. And then, in general, the areas formerly occupied with hematoma show normal or reduced density. One or two days after hemorrhage, the high density is surrounded by a thin low density zone. After a few days the low density area is seen at the anterior and posterior pole of the high density in the white matter. These low density are produced by edema or resolving hematoma. About five days after hemorrhage, high density area is associated with wide surrounding low density zone of edema and then gradually diminishes in size. The wide low density zone surrounding the high density of hematoma persisting for over 15 days is probably composed not only of edema, but also of liquefied hematoma, necrotic brain tissue and so on. Enlarged hematoma and surrounding low density area extend to anterior, posterior, superior and inferior direction in the white matter. CT studies with i.v. contrast enhancement demonstrate from the 2nd to 4th weeks a ring-shaped high density around the hematoma. We classified each of the putaminal and thalamic hemorrhage into four types based on CT findings of hematoma advancement. In this study, a statistical method of Speareman's coefficients of rank correlation was utilized. According to this investigation, the important factors influencing prognosis and operative results were found to be the CT findings including the location and size of a hematoma, as well as the rapidity and the direction of its evolution.

    Jauch, Edward C; Pineda, Jose A; Hemphill, J Claude

    2015-12-01

    Intracerebral hemorrhage (ICH) is a subset of stroke due to bleeding within the parenchyma of the brain. It is potentially lethal, and survival depends on ensuring an adequate airway, reversal of coagulopathy, and proper diagnosis. ICH was chosen as an Emergency Neurological Life Support protocol because intervention within the first critical hour may improve outcome, and it is critical to have site-specific protocols to drive care quickly and efficiently.

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

    The patients were observed by a reanimation-hematological team of the Leningrad emergency service. It has been established that the hemorrhagic syndrome is the main one deterimining the unity of pathogenesis and clinical picture of the hemotransfusional complication. Phase character of the changes in the homeostasis system during the transfusion of incompatible blood was noted. The express diagnosis of the disorders and a scheme of the sequence of administration of hemostatic drugs are proposed. Mortality among such patients was reduced.

Antibiotic sensitivity test was done for the isolate. The ailing animals were successfully treated with antibiotic, analgesic and corticosteroid. The epidemic was finally controlled by therapeutic measures, immunization, restriction of movement of animals and proper disposal of carcasses.

  9. Increased mortality by septicemia, interstitial pneumonitis and pulmonary fibrosis among bone marrow transplant recipients receiving an increased mean dose rate of total irradiation

    Ringden, O.; Baaryd, I.; Johansson, B.

    1983-01-01

    Seven bone marrow transplant recipients with acute lymphoblastic leukemia receiving a mean dose rate of 0.07 Gy/min of total body irradiation towards the pelvic midpoint and the lungs had an increased (p<0.01) overall death rate of 86 per cent compared with 33 per cent among 27 patients with acute non-lymphoblastic leukemia or acute lymphoblastic leukemia treated with a mean dose rate of 0.04 Gy/min. Among the patients receiving the higher dose rate there was an increased mortality in causes related to radiation toxicity like early septicemia, interstitial pneumonitis and pulmonary fibrosis, compared with all patients receiving the lower dose rate (p<0.01) and also with 10 patients from this group with acute lymphoblastic leukemia (p<0.02).

  10. Rehabilitation Outcomes: Ischemic versus Hemorrhagic Strokes.

    Perna, Robert; Temple, Jessica

    2015-01-01

    Background. Ischemic and hemorrhagic strokes have different pathophysiologies and possibly different long-term cerebral and functional implications. Hemorrhagic strokes expose the brain to irritating effects of blood and ischemic strokes reflect localized or diffuse cerebral vascular pathology. Methods. Participants were individuals who suffered either an ischemic (n = 172) or hemorrhagic stroke (n = 112) within the past six months and were involved in a postacute neurorehabilitation program. Participants completed three months of postacute neurorehabilitation and the Mayo Portland Adaptability Inventory-4 (MPAI-4) at admission and discharge. Admission MPAI-4 scores and level of functioning were comparable. Results. Group ANOVA comparisons show no significant group differences at admission or discharge or difference in change scores. Both groups showed considerably reduced levels of productivity/employment after discharge as compared to preinjury levels. Conclusions. Though the pathophysiology of these types of strokes is different, both ultimately result in ischemic injuries, possibly accounting for lack of findings of differences between groups. In the present study, participants in both groups experienced similar functional levels across all three MPAI-4 domains both at admission and discharge. Limitations of this study include a highly educated sample and few outcome measures.

    Fourteen cases of cerebellar hemorrhage were analysed from the point of CT-scan, and the following results were obtained. 1. The number of cases of cerebellar hemorrhage forms 4.4% of that of total intracranial hemorrhage. 2. Most of the cerebellar hematomas extend upward. Downward extension is rare. 3. In acute dead cases hematomas are 5 cm or more in diameter and lie over bilateral hemispheres with the extension to third or fourth ventricles in CT-scans. 4. Slowly progressive cases are detriorated by the secondary hydrocephalus. 5. In mild cases hematomas are 3cm or less in diameter on CT-scans and the hematoma evacuation is not indicated for these cases. 6. The shunt operation alone is sufficient for the life saving of the slowly progressive cases, but the hematoma evacuation is indicated in these cases if the functional prognosis is taken into consideration. 7. Immediate hematoma evacuation together with the ventricular drainage is considered to be effective for the life saving of the acute fulminant cases.

    Full Text Available Objective To analyze the clinical features of multiple spontaneous intracerebral hemorrhages (MICH. Methods Conservative therapy, puncture and drainage, hematoma removal and/or decompressive craniectomy were used in the treatment of 630 intracerebral hemorrhage (ICH patients, who were divided into 2 groups: 30 cases with MICH and another 600 cases with solitary intracerebral hemorrhage (SICH. Three months after onset, modified Rankin Scale (mRS was used to evaluate the prognosis of all cases. Results Compared with patients in SICH group, the occurrence rate of hypertension > 5 years (P = 0.008, diabetes mellitus (P = 0.024, hypercholesterolemia (P = 0.050 and previous ischemic stroke (P = 0.026 were all significantly higher in MICH group. The mean arterial pressure (MAP level (P = 0.002 and the incidence of limb movement disorder (P = 0.000 were significantly higher in patients with MICH than those with SICH. Basal ganglia and thalamus were the predilection sites of hematoma (P = 0.001. Patients with MICH had worse prognosis compared to those with SICH 3 months after onset (P = 0.006. Conclusions Hypertension > 5 years, diabetes mellitus, hypercholesterolemia and ischemic stroke were identified to be the pathophysiological basis of MICH in this study. All patients with MICH had more serious clinical manifestations after onset and worse prognosis. DOI: 10.3969/j.issn.1672-6731.2016.01.008

    Cevik, Belma; Kirbas, Ismail; Cakir, Banu; Akin, Kayihan; Teksam, Mehmet

    2009-01-01

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

  16. Hemorrhage control by microsecond electrical pulses

    Mandel, Yossi; Manivanh, Richard; Dalal, Roopa; Huie, Phil; Wang, Jenny; Brinton, Mark; Palanker, Daniel

    2013-02-01

    Non-compressible hemorrhages are the most common preventable cause of death on battlefield or in civilian traumatic injuries. We report the use of sub-millisecond pulses of electric current to induce rapid constriction in femoral and mesenteric arteries and veins in rats. Extent of vascular constriction could be modulated by pulse duration, amplitude and repetition rate. Electrically-induced vasoconstriction could be maintained at steady level until the end of stimulation, and blood vessels dilated back to their original size within a few minutes after the end of stimulation. At higher settings, a blood clotting could be introduced, leading to complete and permanent occlusion of the vessels. The latter regime dramatically decreased the bleeding rate in the injured femoral and mesenteric arteries, with a complete hemorrhage arrest achieved within seconds. The average blood loss from the treated femoral artery was about 7 times less than that of a non-treated control. This new treatment modality offers a promising approach to non-damaging control of bleeding during surgery, and to efficient hemorrhage arrest in trauma patients.

  17. Detection of 400-year-old Yersinia pestis DNA in human dental pulp: an approach to the diagnosis of ancient septicemia.

    Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections such as plague remains hypothetical. The durability of dental pulp, together with its natural sterility, makes it a suitable material on which to base such research. We hypothesized that it would be a lasting refuge for Yersinia pestis, the plague agent. DNA extracts were made from the dental pulp of 12 unerupted teeth extracted from skeletons excavated from 16th and 18th century French graves of persons thought to have died of plague ("plague teeth") and from 7 ancient negative control teeth. PCRs incorporating ancient DNA extracts and primers specific for the human beta-globin gene demonstrated the absence of inhibitors in these preparations. The incorporation of primers specific for Y. pestis rpoB (the RNA polymerase beta-subunit-encoding gene) and the recognized virulence-associated pla (the plasminogen activator-encoding gene) repeatedly yielded products that had a nucleotide sequence indistinguishable from that of modern day isolates of the bacterium. The specific pla sequence was obtained from 6 of 12 plague skeleton teeth but 0 of 7 negative controls (P plague was achieved for historically identified victims, and we have confirmed the presence of the disease at the end of 16th century in France. Dental pulp is an attractive target in the quest to determine the etiology of septicemic illnesses detected in ancient corpses. Molecular techniques could be applied to this material to resolve historical outbreaks.

    2017-01-01

    Background Children with untreated brain arteriovenous malformations (bAVM) are at risk of encountering life-threatening hemorrhage very early in their lives. The primary aim of invasive treatment is to reduce unfavorable outcome associated with a bAVM rupture. A better understanding of the morbidity of bAVM hemorrhage might be helpful for weighing the risks of untreated bAVM and invasive treatment. Our aim was to assess the clinical outcome after bAVM rupture and identify features to predict severe hemorrhage in children. Methods We identified all consecutive children admitted to our institution for bAVMs between July 2009 and December 2014. Clinical outcome after hemorrhagic presentation and subsequent hemorrhage was evaluated using the modified Rankin Scale (mRS) for children. The association of demographic characteristics and bAVM morphology with severe hemorrhage (mRS >3 or requiring emergency hematoma evacuation) was studied using univariate and multivariable regression analyses. A nomogram based on multivariable analysis was formulated to predict severe hemorrhage risk for individual patients. Results A total of 134 patients were identified with a mean treatment-free follow-up period of 2.1 years. bAVM ruptured in 83 (62%) children: 82 had a hemorrhage at presentation and 6 of them experienced a recurrent hemorrhage during follow-up; 1 patient had other diagnostic symptoms but bled during follow-up. Among them, 49% (41/83) had a severe hemorrhage; emergency hematoma evacuation was required in 28% of them (23/83), and 24% (20/83) remained as disabled (mRS ≥ 3) at last follow-up. Forty-six percent (38/82) of children with hemorrhagic presentation were severely disabled (mRS >3). Forty-three percent (3/7) were severely disabled after subsequent hemorrhage. The annual rate of severe subsequent hemorrhage was 1% in the overall cohort and 3.3% in children with ruptured presentation. All the subsequent severe hemorrhage events occurred in children with severe

    Full Text Available History of present illness: A 35-year-old female presented to the ED with a Glasgow Coma Scale (GCS of 11. Per her boyfriend, the patient was having headaches for the past 3 weeks. She was initially taken to an outside hospital where her GCS was reported as 13. A non-contrast head computed tomography (CT revealed a large lobar intraparenchymal hemorrhage within the left frontal parietal lobe with midline shift. Upon examination, vitals were notable for blood pressure of 209/88mmHg, and her left pupil was fixed and dilated. The patient had extension of her right arm to noxious stimuli, paralysis of her right leg, and purposeful movement of the left arm and left leg. The patient was started on a nicardipine drip in the ED and subsequently taken to the operating room for a decompressive craniectomy. Significant findings: The patient’s head CT showed a significant area of hyperdensity consistent with an intracranial hemorrhage located within the left frontal parietal lobe (red arrow. Additionally, there is rightward midline shift up to 1.1cm (green arrow and entrapment of the right lateral ventricle (blue arrow. Discussion: Intraparenchymal hemorrhage (IPH is associated with high morbidity and mortality. Although the mortality for subarachnoid hemorrhage (SAH has declined steadily over the past several decades, the mortality for IPH mortality has not significantly.1 One of the most serious considerations when treating a patient with IPH is the management of intracranial pressure (ICP.2 Once an IPH is identified, immediate steps should be taken to bring ICP within acceptable levels including elevating the head of the bed to 30 degrees, sedation, and controlling hypertension with medications.2-3 Even with early and aggressive care, the prognosis for IPH remains poor; the 30-day mortality rate for IPH is estimated to be less than 50%, and a 2010 systematic review estimated only 12-39% of IPH patients achieve independent function.4-5 Predictors of

    To describe the chest radiographic and CT findings of diffuse pulmonary hemorrhage. Two radiologists retrospectively analysed the chest radiographic and CT findings of six patients with diffuse pulmonary hemorrhage. Using open lung biopsy(n=3D2) and transbronchial lung biopsy or bronchoalveolar lavage(n=3D4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage. Underlying diseases were Wegener's granulomatosis(n=3D2), antiphospholipid antibody syndrome(n=3D2), Henoch-Schonlein purpura(n=3D1), and idopathic pulmonary hemosiderosis(n=3D1). In all patients, sequential chest radiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patinets, and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns of involvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CT scans. Chest radiographs showed multifocal patchy consolidation(n=3D6), ground-glass opacity(n=3D3), and multiple granular or nodular opacity(n=3D3). These lesions were intermingled in five patients, while in one there was consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonary abnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days, these had almost normalized. HRCT scans showed patchy consolidation(n=3D5), multiple patchy ground-glass opacity(n=3D5), or ill-defined air space nodules(n=3D4). These lesions were intermingled in five patients, and in one, ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intalobular reticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonal predominancy, and spared the apex of the lung and subpleural region were less affected.

Using open lung biopsy(n=3D2) and transbronchial lung biopsy or bronchoalveolar lavage(n=3D4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage. Underlying diseases were Wegener's granulomatosis(n=3D2), antiphospholipid antibody syndrome(n=3D2), Henoch-Schonlein purpura(n=3D1), and idopathic pulmonary hemosiderosis(n=3D1). In all patients, sequential chest radiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patinets, and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns of involvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CT scans. Chest radiographs showed multifocal patchy consolidation(n=3D6), ground-glass opacity(n=3D3), and multiple granular or nodular opacity(n=3D3). These lesions were intermingled in five patients, while in one there was consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonary abnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days, these had almost normalized. HRCT scans showed patchy consolidation(n=3D5), multiple patchy ground-glass opacity(n=3D5), or ill-defined air space nodules(n=3D4). These lesions were intermingled in five patients, and in one, ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intalobular reticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonal predominancy, and spared the apex of the lung and subpleural region were less affected. Although chest radiographic and CT findings of diffuse pulmonary

    Five (9.6%) of 52 cases of supretentorial hypertensive intracerebral hemorrhage which suffered rehemorrhage in the contralateral regions were analyzed in the present study, and the 28 cases reported since 1950 were reviewed. The literature suggests that the time between the first hemorrhage and the second was quite long. However, the present series showed that re-hemorrhage in the contralateral side developed within one month in three out of five cases. In case 1, hemorrhages developed almost simultaneously in the left thalamus and in the right putamen. Three characteristics were observed: The symptoms including hemiparesis and/or hemispheric signs related to the first hemorrhage had a tendency to exacerbate after the second attack in other the contralateral region in the second attack, symptoms excessively severe for the size of the hematoma developed. Finally, the clinical course after the second hemorrhage was poor. (author)

  3. [Renal hemorrhage after ESWL: From small hematoma to renal blowout].

    Panach-Navarrete, Jorge; Palmero Martí, Jose Luis; Ganau Ituren, Amparo; Pastor Lence, Juan Carlos; Benedicto Redón, Antonio

    2016-04-01

    To report two cases of renal hemorrhage after extracorporeal shock wave lithotripsy (ESWL) and their therapeutic management. Description of the clinical cases, together with the diagnosis and therapeutic management of these complications. We present two cases of patients with renal hemorrhage after ESWL, which were performed without immediate complications. One of the cases, after detecting an important laceration of the renal parenchyma, needed two embolization sessions for its short-term resolution; however, the patient finally passed away due to the complications derived from hemorrhage. The other case was solved through conservative management. Even though hemorrhage is an infrequent complication after ESWL, it should be suspected when the patient presents compatible clinical symptoms, since even though most cases are resolved in a conservative manner, on some occasions specific treatments for the hemorrhage are necessary. Old age and the presence of vascular comorbidities seem to be related to a higher risk of hemorrhage after ESWL.

    1. After hemorrhage of 21% blood volume (0.9% body weight) blood pressure (BP) and heart rate (H.R.) of unanesthetized bluefish (Pomatomus saltatrix) recovered within 5 min. 2. Phentolamine blocked this recovery. 3. Atropine increased control H.R. from 48 to 87 per min, and to 108 after hemorrhage, with delay of BP recovery to 10 min. 4. With small, repeated hemorrhages every 20 min, hemodilution and recovery of BP occurred between hemorrhages. Removal of 27% blood volume resulted in only temporary recovery. 5. Thirty min after hemorrhage, plasma epinephrine was 5 x and norepinephrine 8 x control. 6. Thus, bluefish tolerate hemorrhage with initial vasoconstriction via alpha-adrenergic pathways, and hemodilution.

  6. Obstructive Sleep Apnea: An Unusual Cause of Hemorrhagic Stroke.

    Pawar, Nilesh H; O'Riordan, Jennifer A; Malik, Preeti; Vasanwala, Farhad F

    2017-09-27

    Stroke is one of the most common causes of mortality and morbidity worldwide. Hemorrhagic stroke comprises 10-20% of strokes. Here, we present a case report of hemorrhagic stroke that may have been secondary to untreated Obstructive Sleep Apnea (OSA) in a young man with no other cardiovascular risk factors or features of metabolic syndrome. A 32-year-old man was admitted for hemorrhagic stroke. An initial thorough workup for the etiology of stroke was inconclusive. Eventually, a polysomnography was done, which demonstrated OSA suggesting that untreated OSA may have contributed to his stroke. OSA may cause hemorrhagic stroke by nocturnal blood pressure surge. So, all physicians should consider doing polysomnography for unexplained hemorrhagic stroke or in patients at risk. Diagnosing and treating OSA would be critical in preventing hemorrhagic stroke and its recurrences.

    Full Text Available Expulsive suprachoroidal hemorrhage can be surgical or spontaneous. Spontaneous expulsive suprachoroidal hemorrhage (SESCH is a rare entity. Most of the reported cases of SESCH were caused by a combination of corneal pathology and glaucoma. We are reporting a rare presentation of SESCH with no pre-existing glaucoma or corneal pathology and caused by massive intra- and peri-ocular hemorrhage due to decompensated liver disease.

    Intraventricular hemorrhage (IVH) is a cause of significant morbidity and mortality and is an independent predictor of a worse outcome in intracerebral hemorrhage (ICH) and germinal matrix hemorrhage (GMH). IVH may result in both injuries to the brain as well as hydrocephalus. This paper reviews evidence on the mechanisms and potential treatments for IVH-induced hydrocephalus. One frequently cited theory to explain hydrocephalus after IVH involves obliteration of the arachnoid villi by microt...

  9. A clinical study on neonatal intracranial hemorrhage, 2

    Matsuda, Hiroo; Inoue, Takao; Shimura, Kohji

    1980-01-01

    Clinical pigns, laboratory data, CT findings, CSF spectrophotometric findings and CSF/blood glucose ratio were reviewed on thirty six newborns with intracranial hemorrhage confirmed by CT and/or autopsy and the following findings were obtained. The sites of hemorrhage were: intraventricular 14, intracerebral 4, subdural 2, subarachnoidal 16. 1) Convulsion (39%), hypotonia (58%), apnea (47%), and bradycardia (58%) were seen, but those were not regarded as specific for the intracranial hemorrhage. 2) Severe anemia of hemoglobin value less than 14 g/dl (17%), more than 10% fall of hematocrit (10%), and hyperglycemia of blood glucose more than 200 mg/gl (42%) were seen almost equally in every type of hemorrhage. 3) On CSF spectrophotometry, ajj twelve cases of intraventricular and four cases of intracerebral hemorrhage had the oxyhemoglobin peak absorbance. However, of fourteen cases of subarachnoidal hemorrhage, three had the oxyhemoglobin peak absorbance but the other eleven cases had the bilirubin peak absorbance. 4) Hypoglycorrachia, defined as CSF/blood glucose ratio less than 0.4, was recognized only in the intraventricular hemorrhage group (5/9, 56%). It was concluded that lumbar puncture should be done first of all when intracranial hemorrhage is suspected. If hypoglycorrachia or oxyhemoglobin peak absorbance is recognized, computed tomography should be performed immediately to know the accurate site and extent of hemorrhage. Although hypoglycorrachia is more specific for the intraventricular hemorrhage, it is usually found several days after the hemorrhage. On the other hand, oxyhemoglobin can be identified in CSF within a day after the episode of hemorrhage and this method is more benifical for the early diagnosis. (author)

  13. Calcified subdural hematoma associated with hypertensive intracerebral hemorrhage

    Ishige, Naoki; Sunami, Kenro; Sato, Akira; Watanabe, Osamu

    1984-01-01

    A case of calcified subdural hematoma associated with hypertensive intracerebral hemorrhage is reported. A left frontal subdural hematoma with left putaminal hemorrhage was incidentally found when a CT scan was performed to evaluate right hemiparesis and aphasia in a 55-year-old man. The putaminal hemorrhage was not very extensive, but his clinical symptoms were rather serious. Not only the putaminal hemorrhage, but also the presence of the calcified subdural hematoma was considered to have caused his clinical deterioration. The subtotal removal of the calcified subdural hematoma brought about a good result. (author)

  14. Intranasal Fentanyl Intoxication Leading to Diffuse Alveolar Hemorrhage.

    Ruzycki, Shannon; Yarema, Mark; Dunham, Michael; Sadrzadeh, Hossein; Tremblay, Alain

    2016-06-01

    Increasing rates of opioid abuse, particularly fentanyl, may lead to more presentations of unusual effects of opioid toxicity. Diffuse alveolar hemorrhage is a rare complication of fentanyl overdose. A 45-year-old male presented in hypoxic respiratory failure secondary to diffuse alveolar hemorrhage requiring intubation. Comprehensive drug screening detected fentanyl without exposure to cocaine. Further history upon the patient's recovery revealed exposure to snorted fentanyl powder immediately prior to presentation. Diffuse alveolar hemorrhage is a potential, though rare, presentation of opioid intoxication. Recognition of less common complications of opioid abuse such as diffuse alveolar hemorrhage is important in proper management of overdoses.

  15. Herpes Simplex Encephalitis Complicated by Cerebral Hemorrhage during Acyclovir Therapy.

    Harada, Yukinori; Hara, Yuuta

    2017-01-01

    Herpes simplex encephalitis (HSE) can be complicated by adverse events in the acute phase. We herein present the case of a 71-year-old woman with HSE complicated by cerebral hemorrhage. She presented with acute deterioration of consciousness and fever and was diagnosed with HSE based on the detection of herpes simplex virus-1 in the cerebrospinal fluid by a polymerase chain reaction. The cerebral hemorrhage developed during acyclovir therapy; however, its diagnosis was delayed for 2 days. After the conservative treatment of the cerebral hemorrhage, the patient made a near-complete recovery. Cerebral hemorrhage should be considered as an acute-phase complication of HSE.

  16. CT appearance of renal hemorrhage after extracorporeal shock wave lithotripsy

    Kanazawa, Susumu; Araki, Toru; Takamoto, Hitoshi; Hata, Kazuhiro

    1988-07-01

    Computed Tomography (CT) was performed in three patients who were suspicious of renal hemorrhage after extracorporeal shock wave lithotripsy (ESWL). Post-ESWL scans demonstrated subcapsular hematoma in all three cases, and intrarenal hemorrhage in two cases, one of which had fluid collection in the pararenal space and hemorrhage in the posterior pararenal space on CT. Thickening of gerota fascia and bridging septa in the perirenal space was visualized on CT in all of them. CT demonstrated clearly the anatomic distribution and extent of renal hemorrhage, and it is important to comprehend the imaging anatomy of the perirenal area for CT evaluation.

    Full Text Available Spontaneous adrenal hemorrhage is an acute hemorrhage during pregnancy, which can be tragic for the mother and the baby. We report a unique spontaneous hemorrhage during pregnancy in a case with horseshoe kidney with separated adrenal, presented for the first time in the world. Computed tomography scan showed a horseshoe kidney fused with left normal kidney. Interestingly the adrenal gland was remained in right flank and separated from the horseshoe kidney, which prepares a probable physical stress for the hemorrhage. Diagnosis and surgery were done successfully and the case was fully recovered after several days.

    Determine the prevalence of intraventricular hemorrhage in infants with moderate to severe congenital heart disease, investigate the impact of gestational age, cardiac diagnosis, and cardiac intervention on intraventricular hemorrhage, and compare intraventricular hemorrhage rates in preterm infants with and without congenital heart disease. A single-center retrospective review. A tertiary care children's hospital. All infants admitted to St. Louis Children's Hospital from 2007 to 2012 with moderate to severe congenital heart disease requiring cardiac intervention in the first 90 days of life and all preterm infants without congenital heart disease or congenital anomalies/known genetic diagnoses admitted during the same time period. None. Cranial ultrasound data were reviewed for presence/severity of intraventricular hemorrhage. Head CT and brain MRI data were also reviewed in the congenital heart disease infants. Univariate analyses were undertaken to determine associations with intraventricular hemorrhage, and a final multivariate logistic regression model was performed. There were 339 infants with congenital heart disease who met inclusion criteria and 25.4% were born preterm. Intraventricular hemorrhage was identified on cranial ultrasound in 13.3% of infants, with the majority of intraventricular hemorrhage being low-grade (grade I/II). The incidence increased as gestational age decreased such that intraventricular hemorrhage was present in 8.7% of term infants, 19.2% of late preterm infants, 26.3% of moderately preterm infants, and 53.3% of very preterm infants. There was no difference in intraventricular hemorrhage rates between cardiac diagnoses. Additionally, the rate of intraventricular hemorrhage did not increase after cardiac intervention, with only three infants demonstrating new/worsening high-grade (grade III/IV) intraventricular hemorrhage after surgery. In a multivariate model, only gestational age at birth and African-American race were predictors

  5. Spontaneous subdural hematoma associated to Duret hemorrhage

    William Alves Martins, MD

    2015-03-01

    Full Text Available Subdural hematoma (SH is a neurosurgical emergency, usually caused by head trauma. Non-traumatic causes include aneurysm or arterial–venous malformation rupture, coagulopathy and others. We report the case of a 66 year-old man who developed apparently unprovoked signs of increased intracranial pressure. Brain computed tomography scan showed an acute spontaneous SH, surgically treated. Throughout surgery, a ruptured cortical artery with intensive bleeding appeared and was cauterized. After surgery, patient remained comatose and a new CT demonstrated Duret hemorrhage at the brainstem. Acute spontaneous SH of arterial origin is rare and highly lethal, in which a good prognosis relies on early diagnosis and treatment.

    Vives, Daniel A.; Bauni, Carlos E.; Mendoza, Monica E.

    2003-01-01

    Rendu-Osler-Weber disease or Hereditary Hemorrhagic Telangiectasia (HHT) is a generalized familial angiodysplastic disorder. The neurological manifestations of this entity are due to Central Nervous System vascular lesions or to complications of other visceral lesions such as pulmonary arteriovenous fistulae. This report describes two patients (males, 40 and 61 years old), with brain abscesses associated with HHT. The CT, MRI and Angiographic findings as well as the therapeutic approach are analyzed. Patients with brain abscess of unknown origin must be evaluated for the presence of lung vascular malformation in association with HHT. (author)

  7. Hemodynamics in patients with hypertensive intracerebral hemorrhage

    Kitahara, Tetsuhiro

    1997-01-01

    Cerebral hemodynamics in 15 patients with hypertensive intracerebral hemorrhage (HICH) were evaluated by measuring cerebral blood flow (CBF) and cerebrovascular reserve capacity, using stable xenon-enhanced computed tomography. Their hematomas were removed by stereotactic aqua stream aspiration. The hemispheric and thalamic CBFs of patients with HICH were lower than those of hypertensive patients without hematomas. However, the hemispheric CBF increased according to how much of the hematoma was removed surgically. Thus, hemodynamics in patients with HICH can be improved by surgical hematoma removal, although some adjunct therapies are necessary in order to prevent secondary edema and the delayed neuronal death.

    Swensen, S.J.; McLeod, R.A.; Stephens, D.H.

    1984-01-01

    Computed tomography was used to examine 100 patients with extracranial hemorrhage. Of these patients, 29 had serial scans that allowed for the study of evolutionary changes. Operation, anticoagulation, and trauma were the prime etiological factors. The most frequent sites included the retroperitoneum (27%), body wall or extremities (24%), peritoneal cavity (19%), and subcapsular (16%) and intraparenchymal (7%) locations. The computed tomographic features were carefully studied and documented. Age-related features included contrast-material extravasation, inhomogeneity, hematocrit effect, attenuation changes, lucent halo, pseudocapsule development, decreased size with time, peripheral calcification, and fascial plane thickening. This report discussed all these findings and their usefulness in diagnosis and patient care

  9. Hemorrhage Near Fetal Rat Bone: Preliminary Results

    Bigelow, Timothy A.; Miller, Rita J.; Blue, James P.; O'Brien, William D.

    2006-05-01

    High-intensity ultrasound has shown potential in treating many ailments requiring noninvasive tissue necrosis. However, little work has been done on using ultrasound to ablate pathologies on or near the developing fetus. For example, Congenital Cystic Adenomatoid Malformation (cyst on lungs), Sacrococcygeal Teratoma (benign tumor on tail bone), and Twin-Twin Transfusion Syndrome (one twin pumps blood to other twin) are selected problems that will potentially benefit from noninvasive ultrasound treatments. Before these applications can be explored, potential ultrasound-induced bioeffects should be understood. Specifically, ultrasound-induced hemorrhage near the fetal rat skull was investigated. An f/1 spherically focused transducer (5.1-cm focal length) was used to expose the skull of 18- to 19-day-gestation exteriorized rat fetuses. The ultrasound pulse had a center frequency of 0.92 MHz and pulse duration of 9.6 μs. The fetuses were exposed to 1 of 4 exposure conditions (denoted A, B, C, and D) in addition to a sham exposure. Three of the exposures consisted of a peak compressional pressure of 10 MPa, a peak rarefactional pressure of 6.7 MPa, and pulse repetition frequencies of 100 Hz (A), 250 Hz (B), and 500 Hz (C), corresponding to time-average intensities of 1.9 W/cm2, 4.7 W/cm2, and 9.4 W/cm2, respectively. Exposure D consisted of a peak compressional pressure of 6.7 MPa, a peak rarefactional pressure of 5.0 MPa, and a PRF of 500 Hz corresponding to a time-average intensity of 4.6 W/cm2. Hemorrhage occurrence increased slightly with increasing time-average intensity (i.e., 11% for A, 28% for B, 31% for C, and 19% for D with a 9% occurrence when the fetuses were not exposed). The low overall occurrence of hemorrhaging may be attributed to fetal motion (observed in over half of the fetuses from the backscattered echo during the exposure). The mean hemorrhage sizes were 3.1 mm2 for A, 2.5 mm2 for B, 2.7 mm2 for C, and 5.1 mm2 for D. The larger lesions at D may

    Emerging data suggest intraventricular hemorrhage (IVH) of the preterm neonate is a complex disorder with contributions from both the environment and the genome. Environmental analyses suggest factors mediating both cerebral blood flow and angiogenesis contribute to IVH, while candidate gene studies report variants in angiogenesis, inflammation, and vascular pathways. Gene-by-environment interactions demonstrate the interaction between the environment and the genome, and a non-replicated genome-wide association study suggests that both environmental and genetic factors contribute to the risk for severe IVH in very low-birth weight preterm neonates.

  11. The pathogenesis of Ebola hemorrhagic fever.

    Takada, A; Kawaoka, Y

    2001-10-01

    Ebola virus causes lethal hemorrhagic disease in humans, yet there are still no satisfactory biological explanations to account for its extreme virulence. This review focuses on recent findings relevant to understanding the pathogenesis of Ebola virus infection and developing vaccines and effective therapy. The available data suggest that the envelope glycoprotein and the interaction of some viral proteins with the immune system are likely to play important roles in the extraordinary pathogenicity of this virus. There are also indications that genetically engineered vaccines, including plasmid DNA and viral vectors expressing Ebola virus proteins, and passive transfer of neutralizing antibodies could be feasible options for the control of Ebola virus-associated disease.

  12. Nonbacterial thrombotic endocarditis presenting as intracerebral hemorrhage.

    Wigger, Olivier; Windecker, Stephan; Bloechlinger, Stefan

    2016-12-01

    Nonbacterial thrombotic endocarditis is a rare cause of valvular heart disease, most commonly associated with advanced malignancy. The morbidity of this kind of endocarditis lies in its tendency to embolize, while the valve function is usually preserved. The central nervous system is the most common site of embolization, leading to ischemic stroke. We report a case of nonbacterial thrombotic endocarditis complicated by intracerebral hemorrhage as the first manifestation of adenocarcinoma of the lung. The endocarditis led to severe aortic regurgitation. In view of the advanced stage of lung cancer, the patient refused further therapy. He passed away 3 weeks after first diagnosis of the adenocarcinoma.

  13. Arachnoid granulation affected by subarachnoid hemorrhage

    R.P. Chopard

    1993-11-01

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

    Concomitant acute ischemic lesions are detected in up to a quarter of patients with spontaneous intracerebral hemorrhage (ICH). Influence of bleeding pattern and intraventricular hemorrhage (IVH) on risk of ischemic lesions has not been investigated. Retrospective study of all 500 patients enrolled in the CLEAR III randomized controlled trial of thrombolytic removal of obstructive IVH using external ventricular drainage. The primary outcome measure was radiologically confirmed ischemic lesions, as reported by the Safety Event Committee and confirmed by two neurologists. We assessed predictors of ischemic lesions including analysis of bleeding patterns (ICH, IVH and subarachnoid hemorrhage) on computed tomography scans (CT). Secondary outcomes were blinded assessment of mortality and modified Rankin scale (mRS) at 30 and 180 days. Ischemic lesions occurred in 23 (4.6%) during first 30 days after ICH. Independent risk factors associated with ischemic lesions in logistic regression models adjusted for confounders were higher IVH volume (p = 0.004) and persistent subarachnoid hemorrhage on CT scan (p = 0.03). Patients with initial IVH volume ≥ 15 ml had five times the odds of concomitant ischemic lesions compared to IVH volume < 15 ml. Patients with ischemic lesions had significantly higher odds of death at 1 and 6 months (but not poor outcome; mRS 4-6) compared to patients without concurrent ischemic lesions. Occurrence of ischemic lesions in the acute phase of IVH is not uncommon and is significantly associated with increased early and late mortality. Extra-parenchymal blood (larger IVH and visible subarachnoid hemorrhage) is a strong predictor for development of concomitant ischemic lesions after ICH.

  1. Relationship between hypertensive cerebral hemorrhage and ischemic lesions

    Yamaguchi, Shinya; Tsuchiya, Takashi; Yamaguchi, Takenori

    1991-01-01

    Patchy parenchymal lesions of increased intensity were frequently identified in patients with cerebral hemorrhage in T2-weighted image of high-fields MR imaging. We studied 64 patients with brain hemorrhage to determine the frequency and distribution of those lesions. We defined an area with high intensity in T2 weighted and low or iso-intensity area in T1 weighted images smaller than 1.5 cm in diameter to be 'ischemic lesion'. Ishemic lesions were found in 48 (75%) of all cases; in 25 (75%) of 32 patients with putaminal hemorrhage, in 15 (100%) of 15 with thalamic hemorrhage, in 3 (33%) of 9 with subcortical hemorrhage. Multiple ischemic lesions were more frequently seen in thalamic hemorrhage than in putaminal hemorrhage. Only 5 (10%) of 48 cases with associated ischemic lesions had a previous history related to those lesions. Multivariable regression analysis identified hypertension as the major predictor of the presence of ischemic lesions. Patients with brain hemorrhage frequently accompanied with incidental ischemic lesions, making it difficult to establish a guideline of blood pressure control for prevention of recurrent stroke.

    2009-01-01

    Objective: To analyze CT and MRI features of traumatic basal ganglia hemorrhage and investigate the diagnostic value. Methods: 21 cases with traumatic basal ganglia hemorrhage diagnosed by clinic, CT and MRI in our hospital were collected in this study Plain CT scan were immediately performed in 21 cases after injury, plain MR scan were performed in 1 to 3 days. 12 cases of them underwent diffusion weighted imagine (DWI). The CT and MRI findings were retrospectively summarized. Results: 8 cases were found with simple traumatic basal ganglia hemorrhage. Complexity of basal ganglia hemorrhage occurred in 13 cases, 6 cases combined with subdural hemorrhage, 3 cases with epidural hematoma, 2 cases with subarachnoid hemorrhage, 6 cases with brain contusion and laceration in other locations, 4 cases with skull fracture. 26 lesions of basal ganglia hematoma were showed in 21 cases, 14 lesions of pallidum hemorrhage in 11 cases confirmed by MR could not be distinguished from calcification at the fast CT scan. 5 more lesions of brain contusion and laceration and 4 more lesions of brain white matter laceration were found by MR. Conclusion: CT in combination with MRI can diagnose traumatic basal ganglia hemorrhage and its complications early, comprehensively and accurately, which plays an important role in the clinical therapy selection and prognosis evaluation.

  5. Glibenclamide for the Treatment of Ischemic and Hemorrhagic Stroke

    Nicholas Caffes

    2015-03-01

    Full Text Available Ischemic and hemorrhagic strokes are associated with severe functional disability and high mortality. Except for recombinant tissue plasminogen activator, therapies targeting the underlying pathophysiology of central nervous system (CNS ischemia and hemorrhage are strikingly lacking. Sur1-regulated channels play essential roles in necrotic cell death and cerebral edema following ischemic insults, and in neuroinflammation after hemorrhagic injuries. Inhibiting endothelial, neuronal, astrocytic and oligodendroglial sulfonylurea receptor 1–transient receptor potential melastatin 4 (Sur1–Trpm4 channels and, in some cases, microglial KATP (Sur1–Kir6.2 channels, with glibenclamide is protective in a variety of contexts. Robust preclinical studies have shown that glibenclamide and other sulfonylurea agents reduce infarct volumes, edema and hemorrhagic conversion, and improve outcomes in rodent models of ischemic stroke. Retrospective studies suggest that diabetic patients on sulfonylurea drugs at stroke presentation fare better if they continue on drug. Additional laboratory investigations have implicated Sur1 in the pathophysiology of hemorrhagic CNS insults. In clinically relevant models of subarachnoid hemorrhage, glibenclamide reduces adverse neuroinflammatory and behavioral outcomes. Here, we provide an overview of the preclinical studies of glibenclamide therapy for CNS ischemia and hemorrhage, discuss the available data from clinical investigations, and conclude with promising preclinical results that suggest glibenclamide may be an effective therapeutic option for ischemic and hemorrhagic stroke.

  8. CT findings of subarachnoid hemorrhage due to ruptured cerebral aneurysm

    Kim, Pyo Nyun; Bae, Won Kyung; Kim, Il Young; Lee, Kyung Soo; Lee, Byoung Ho; Kim, Ki Jung

    1990-01-01

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

  13. [Enteroviruses responsible for acute hemorrhagic conjunctivitis].

    Lévêque, N; Huguet, P; Norder, H; Chomel, J-J

    2010-04-01

    Acute hemorrhagic conjunctivitis (AHC) is an epidemic form of highly contagious conjunctivitis, characterized by conjunctival hemorrhages. The first AHC outbreak was described in 1969 in Ghana, West Africa, and was called Apollo disease, from the Apollo landing on the moon. This outbreak was caused by Enterovirus 70 (EV70) together with a Coxsackievirus A24 (CVA24v) variant, which are the major etiological agents involved in AHC outbreaks worldwide. AHC is known to be directly transmitted by close person-to-person contact or indirectly through soiled ophthalmological materials or unsafe recreational water. Recently, a possible airborne virus spread was suggested which could explain the high transmission rate of the disease. In the absence of a specific antiviral therapy, a rapid diagnosis of the causative agent is required to distinguish AHC due to enteroviruses from other ocular infectious diseases, for there are active drugs, or to quickly implement proper public health measures to limit the extension of the outbreak. However, virus identification remains difficult and time-consuming. Moreover, virological diagnosis is difficult to implement in developing countries where AHC has recently become a major problem for public health. Copyright 2009 Elsevier Masson SAS.

  14. Intracranial hemorrhage in congenital bleeding disorders.

    Tabibian, Shadi; Motlagh, Hoda; Naderi, Majid; Dorgalaleh, Akbar

    2018-01-01

    : Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

  15. Pseudoparasitic Liesegang structures in perirenal hemorrhagic cysts.

    Sneige, N; Dekmezian, R H; Silva, E G; Cartwright, J; Ayala, A G

    1988-02-01

    Periodic structures with equally spaced radial striations identified as Liesegang-like rings were seen in two male patients' hemorrhagic perirenal cysts. The patients, one 48 and the other 60 years old, had acute right-flank pain and anemia; both had nephrectomy. The rings, initially believed to represent parasites (Dioctophyma renale), were from 8 to 500 micron in diameter and had uniform, pink-tan, radially striated double walls. Multiple small rings within a larger ring predominated in one case. Morphologically, the rings differed from D. renale when compared with specimens from animals infected naturally or experimentally with the giant kidney worm. Histochemical and immunoperoxidase tests for iron, calcium, mucopolysaccharides, amyloid, keratin, and hemoglobin had negative results. Energy-dispersive x-ray elemental analysis demonstrated no detectable elements; ultrastructurally, however, the rings displayed a fine fibrillary composition with a concentric and radial pattern. These rings are believed to be an end product of a phenomenon resembling or are, in fact, the Liesegang phenomenon. Because these Liesegang-like structures may be mistaken for parasites on fine-needle aspiration or surgical specimens of hemorrhagic areas, pathologists should be aware of them.

  16. Spontaneous subarachnoid hemorrhage in the emergency department

    2012-07-01

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

    Postpartum hemorrhage (PPH) is a potentially life threatening condition, and it remains the leading cause of maternal morbidity. Uterine atony, lower genital tract lacerations, uterine rupture or inversion, retained products of conception and underlying coagulopathy are some of the common causes of PPH. Most conditions can be diagnosed based on clinical and laboratory evaluation supplemented by ultrasound information. Computed tomography (CT) or magnetic resonance (MR) imaging can provide information for the detection, localization and characterization of PPH in some difficult cases. CT can accurately demonstrate the anatomic location of significant arterial hemorrhage as sites of intravenous contrast material extravasation, which can be as a guide for angiographic intervention. The presence of focal or diffuse intravenous contrast extravasation or a hematoma within the enlarged postpartum uterine cavity on CT can help the diagnosis of uterine atony when the clinical diagnosis of uterine atony is unclear. CT can also provide the information of other alternative conditions such as a puerperal genital hematoma, uterine rupture and concealed hematoma in other sites. MR imaging may be considered as a valuable complement to ultrasound where the ultrasound findings are inconclusive in the diagnosis and differential diagnosis of retained products of conception. Knowledge of the various radiologic appearances of PPH and the correlation with clinical information can ensure correct diagnosis and appropriate and prompt treatment planning in the patients with PPH.

    The authors report a case of intracranial epidural hemorrhage (ICEH) during spinal surgery. We could not find ICEH, though we recorded transcranial electrical stimulation motor evoked potentials (TcMEPs). A 35-year-old man was referred for left anterior thigh pain and low back pain that hindered sleep. Sagittal T2-weighted magnetic resonance imaging revealed an intradural tumor at L3-L4 vertebral level. We performed osteoplastic laminectomy and en bloc tumor resection. TcMEPs were intraoperatively recorded at the bilateral abductor digiti minimi (ADM), quadriceps, tibialis anterior and abductor hallucis. When we closed a surgical incision, we were able to record normal TcMEPs in all muscles. The patient did not fully wake up from the anesthesia. He had right-sided unilateral positive ankle clonus 15 min after surgery in spite of bilateral negative of ankle clonus preoperatively. Emergent brain computed tomography scans revealed left epidural hemorrhage. The hematoma was evacuated immediately via a partial craniotomy. There was no restriction of the patient's daily activities 22 months postoperatively. We should pay attention to clinical signs such as headache and neurological findgings such as DTR and ankle clonus for patients with durotomy and cerebrospinal fluid (CSF) leakage. Spine surgeons should know that it was difficult to detect ICEH by monitoring with TcMEPs.

  20. CLINICAL APPROACH TO HEREDITARY HEMORRHAGIC TELANGIECTASIA

    Mary Hachmeriyan

    2013-11-01

    Full Text Available Background: Hereditary hemorrhagic telangiectasia (HHT or Rendu-Osler-Weber disease is a rare syndrome, inherited as an autosomal dominant trait with incidence of 1/10000. The clinical manifestations are due to vascular malformations and predisposition to hemorrhages in different organs, the leading symptom being recurrent epistaxis. If diagnosed with HHT, the patient and his relatives and especially children have to be screened for occult vascular malformations.Case report: A 30 years old woman was treated for cerebral stroke, epistaxis, anemia, arterio-venous malformations for over 6 months. Only at this point she was diagnosed with HHT, after noticing the typical mucosal changes. Focused family history revealed symptoms of HHT in her only child, her father, aunt and two cousins The child was screened for occult vascular malformations – attainment of the nasal mucosa, lungs, gastrointestinal system, liver and brain. Pulmonary and gastrointestinal arterio-venous malformations were proven.Conclusion: Any case of recurrent epistaxis should be evaluated for HHT. After confirmation of the diagnosis every patient and close relatives have to be screened for attainment of other organs and followed up in order to prevent severe life threatening complications.

  1. Virucidal activity of two Iodophors to salmonid viruses

    Amend, Donald F.; Pietsch, John P.

    1972-01-01

    Wescodyne® and Betadine®, organic iodine complexes, were compared in vitro for virucidal activity against infectious hematopoietic necrosis (IHN), infectious pancreatic necrosis (IPN), and viral hemorrhagic septicemia (VHS) viruses. Both iodophors were about equally effective on all three viruses. Each iodophor completely destroyed IHN virus within 30 sec at 12 ppm iodine, and was not affected by water hardness. Virucidal activity, however, was reduced at pH levels above 8.0 and in the presence of organic matter. Wescodyne was also compared with seven disinfectants commonly used in fish hatcheries, for virucidal properties against IHN virus. Wescodyne and chlorine were the only disinfectants to completely destroy the virus. Either Wescodyne or Betadine would effectively destroy the salmonid viruses at less than 25 ppm iodine within 5 min in solutions near neutrality.

  2. Hemorrhagic Transformation of Scrub Typhus Encephalitis: A Rare Entity.

    Kim, H-C; Yoon, K-W; Yoo, D-S; Cho, C-S

    2015-12-01

    Central nervous system (CNS) involvement of scrub typhus infection is well known. Most CNS involvement of scrub typhus infection present as meningitis or encephalitis. We report on a patient suffering from hemorrhagic transformation of intracranial lesions caused by Orientia tsutsugamushi. A 53-year-old female farmer who was infected by scrub typhus was treated with doxycycline and recovered from the systemic illness. However, headache persisted. Brain radiologic studies revealed acute intracranial hemorrhage and enhancing lesion, which implied a CNS involvement. Hemorrhagic transformation of encephalitis by scrub typhus is very rare complication and to our best knowledge, this is the first report of hemorrhagic transformation of scrub typhus encephalitis. Clinician should consider the possibility of hemorrhagic transformation of encephalitis in cases of scrub typhus infection.

    Uglietta, J.P.; Boyko, O.B.; O'Connor, C.M.; Aldrich, H.; Massey, E.W.; Heinz, E.R.

    1990-01-01

    This paper determines the incidence and types of intracranial hemorrhage (ICH) in 1,696 patients treated with thrombolytic therapy for acute myocardial infarction (AMI). Thirteen of 1,696 patients experienced ICH, and their nonenhanced brain CT scans were reviewed. Their mean age was 62 years (range, 53-74 years), and nine of 13 were male. Six patients received tissue plasminogen activator (tPA), four streptokinase, two urokinase, and one tPA and urokinase. The hemorrhages were classified according to CT location: intraparenchymal (IPH), subarachnoid (SAH), subdural (SDH), and intraventricular (IVH). The incidence of ICH was 0.76%. There were 31 hemorrhages in 13 patients. Twelve hemorrhages were IPH, 10 were SDH, seven were SAH, and two were IVH. Excluding IVH, 24 of 29 hemorrhages (83%) were supratentorial

  5. Cerebral blood flow in patients with hypertensive intracerebral hemorrhage

    Sugiyama, Hirotaka

    1984-01-01

    Cerebral blood flow (CBF) is usually decreased in patients with hypertensive intracerebral hemorrhage. A total of 81 regional CBF measurements were performed using an Anger-type dynamic gamma camera with the Xe-133 intracarotid injection technique in 23 patients with thalamic hemorrhage, 18 with small putaminal hemorrhage, and 5 with large putaminal hemorrhage. The results were as follows: Bilateral CBF in thalamic hemorrhages was markedly reduced from 1 week to 2 or 3 weeks after onset; it then showed a tendency to increase from 4 weeks to 3 months. In putaminal hemorrhages, however, CBF in the affected hemisphere did not tend to increase despite increased CBF in the contralateral hemisphere. CBF of the affected hemisphere was plotted against the hematoma volume, and the biphasic curve showed an initial steep and subsequent gentle slope in both putaminal and thalamic hemorrhages. The degree of CBF reduction in the affected hemisphere was more evident in thalamic than in putaminal hemorrhages. However, the flow reduction in the contralateral hemisphere was more obvious in thalamic than in putaminal hemorrhages. Factors such as mean arterial blood pressure, partial pressure of arterial carbon dioxide, cerebrospinal fluid pressure, hematocrit and the degree of involvement of the internal capsule, as shown on CT scan were not directly related to CBF reduction. In conclusion, it is unlikely that the mass effect of the hematoma plays an important role in the discrepancy between CBF reduction in putaminal and thalamic hemorrhages. Rather, the discrepancy may result from the impairment of respective anatomical sites in the thalamic and putaminal regions. It is also suggested that ipsilateral as well as contralateral CBF reduction is probably caused by the decreased cortical metabolic demand. This may be based on the disruption of the transneural fiber pathways, which connect both the thalamus and putamen to the cerebral cortex. (author)

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

  7. Intraventricular hemorrhage in preterm infants: coagulation perspectives.

    Kuperman, Amir A; Kenet, Gili; Papadakis, Emmanuel; Brenner, Benjamin

    2011-10-01

    It has long been considered that a severe coagulation deficiency in premature newborns could be a major contributing factor in the occurrence of intraventricular hemorrhage (IVH). High-grade IVH has also been shown to coincide with severe derangement of coagulation in extremely low birth weight infants. This review focuses on the relevance of the physiologically developing immature hemostatic system to IVH, and the potential benefit of agents affecting hemostasis for IVH therapy or prevention in preterm infants. The findings of small, open-label interventional studies on the effect of ethamsylate, vitamin K, fresh frozen plasma, recombinant activated factor VII, and prothrombin complex concentrate on the premature coagulation system will be reviewed. © Thieme Medical Publishers.

  8. Treatment of Rectal Hemorrhage by Coil Embolization

    Dobson, Craig Charles; Nicholson, Anthony A.

    1998-01-01

    Four patients, aged 54-84 years, presenting with life-threatening rectal bleeding from the superior hemorrhoidal artery, underwent percutaneous fibered platinum coil embolization via coaxial catheters. Pre-procedure sigmoidoscopy had failed to identify the source of hemorrhage, because the rectum was filled with fresh blood. Embolization was technically and clinically successful in all four patients. Subsequent sigmoidoscopy confirmed the diagnoses in three patients as a solitary rectal ulcer, iatrogenic traumatic ulceration following manual evacuation, and a rectal Dieulafoy's lesion. The other case was angiographically seen to be due to a rectal angiodysplasia. Embolization is an effective procedure in life-threatening superior hemorrhoidal arterial bleeding when endoscopic treatment fails, and should be preferred to rectosigmoid resection

  11. Bilateral adrenal hemorrhage in polycythemia vera

    Shruti Bhandari

    2016-09-01

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

  12. Immunological features underlying viral hemorrhagic fevers.

    Messaoudi, Ilhem; Basler, Christopher F

    2015-10-01

    Several enveloped RNA viruses of the arenavirus, bunyavirus, filovirus and flavivirus families are associated with a syndrome known as viral hemorrhagic fever (VHF). VHF is characterized by fever, vascular leakage, coagulation defects and multi organ system failure. VHF is currently viewed as a disease precipitated by viral suppression of innate immunity, which promotes systemic virus replication and excessive proinflammatory cytokine responses that trigger the manifestations of severe disease. However, the mechanisms by which immune dysregulation contributes to disease remain poorly understood. Infection of nonhuman primates closely recapitulates human VHF, notably Ebola and yellow fever, thereby providing excellent models to better define the immunological basis for this syndrome. Here we review the current state of our knowledge and suggest future directions that will better define the immunological mechanisms underlying VHF. Copyright © 2015 Elsevier Ltd.

  13. Digitally quantifying cerebral hemorrhage using Photoshop and Image J.

    Tang, Xian Nan; Berman, Ari Ethan; Swanson, Raymond Alan; Yenari, Midori Anne

    2010-07-15

    A spectrophotometric hemoglobin assay is widely used to estimate the extent of brain hemorrhage by measuring the amount of hemoglobin in the brain. However, this method requires using the entire brain sample, leaving none for histology or other assays. Other widely used measures of gross brain hemorrhage are generally semi-quantitative and can miss subtle differences. Semi-quantitative brain hemorrhage scales may also be subject to bias. Here, we present a method to digitally quantify brain hemorrhage using Photoshop and Image J, and compared this method to the spectrophotometric hemoglobin assay. Male Sprague-Dawley rats received varying amounts of autologous blood injected into the cerebral hemispheres in order to generate different sized hematomas. 24h later, the brains were harvested, sectioned, photographed then prepared for the hemoglobin assay. From the brain section photographs, pixels containing hemorrhage were identified by Photoshop and the optical intensity was measured by Image J. Identification of hemorrhage size using optical intensities strongly correlated to the hemoglobin assay (R=0.94). We conclude that our method can accurately quantify the extent of hemorrhage. An advantage of this technique is that brain tissue can be used for additional studies. Published by Elsevier B.V.

  15. Krypton laser membranotomy in the treatment of dense premacular hemorrhage.

    Chen, Yung-Jen; Kou, His-Kung

    2004-12-01

    Neodymium:YAG (Nd:YAG) laser and argon laser membranotomy have been used in patients with premacular hemorrhage to drain premacular blood into the vitreous cavity and rapidly clear the hemorrhage. However, the Nd:YAG laser appears to be difficult to use, and argon laser energy may be more likely to be absorbed by the ocular media. We performed a study to evaluate the safety and effectiveness of krypton laser membranotomy in selected cases of premacular hemorrhage. Sixteen patients (17 eyes) with dense premacular hemorrhage for 2 weeks or less were enrolled from April 1998 to February 2004. The causes of premacular hemorrhage were proliferative diabetic retinopathy (PDR) in 12 eyes, Valsalva retinopathy in 3 eyes, leukemia in I eye and retinal arterial macroaneurysm in I eye. Krypton laser was used to create a membranotomy on the sloping edge of the premacular hemorrhage. Five eyes with PDR were treated with inferior panretinal photocoagulation and laser membranotomy simultaneously. After intravitreal dispersion of premacular blood, fundus examination was performed in all eyes and fluorescein angiography in five eyes to evaluate retinal damage. All eyes had visual improvement within 2 weeks postoperatively. No retinal damage was seen at the site of membranotomy in any eye. No eye needed vitrectomy postoperatively during a mean follow-up duration of 18.6 months. Krypton laser membranotomy appears to be a safe and simple alternative procedure for treating selected cases of premacular hemorrhage. Further trials are necessary to evaluate its benefit.

  16. Central Methysergide Prevents Renal Sympathoinhibition and Bradycardia during Hypotensive Hemorrhage

    Veelken, Roland; Johnson, Kim; Scrogin, Karie E.

    1998-01-01

    Central methysergide prevents renal sympathoinhibition and bradycardia during hypotensive hemorrhage. Mean arterial pressure (MAP), heart rate (HR), and renal sympathetic nerve activity (RSNA) were measured in conscious rats during either hemorrhage or cardiopulmonary receptor stimulation with phenylbiguanide (PBG) after intracerebroventricular injection of the 5-HT1/5-HT2-receptor antagonist, methysergide (40 microg). Progressive hemorrhage caused an initial rise (109 +/- 33%) followed by a fall in RSNA (-60 +/- 7%) and a fall in HR (-126 +/- 7 beats/min). Methysergide delayed the hypotension and prevented both the sympathoinhibitory and bradycardic responses to hemorrhage. Systemic 5-HT3-receptor blockade did not influence responses to hemorrhage. The PBG infusion caused transient depressor(-25 +/- 6 mmHg), bradycardic (-176 +/- 40 beats/min), and renal sympathostimulatory (182 +/-47% baseline) responses that were not affected by central methysergide (-20 +/- 6 mmHg, -162 +/- 18 beats/min, 227 +/- 46% baseline). These data indicate that a central serotonergic receptor-mediated component contributes to the sympathoinhibitory and bradycardic responses to hypotensive hemorrhage in conscious rats. Furthermore, the same central 5-HT-receptor populations involved in reflex responses to hypotensive hemorrhage probably do not mediate the sympathoinhibitory response to cardiopulmonary chemosensitive 5-HT3 receptors.

  17. Hyponatremia in Patients with Spontaneous Intracerebral Hemorrhage

    Jaime Robenolt Gray

    2014-11-01

    Full Text Available Hyponatremia is the most frequently encountered electrolyte abnormality in critically ill patients. Hyponatremia on admission has been identified as an independent predictor of in-hospital mortality in patients with spontaneous intracerebral hemorrhage (sICH. However, the incidence and etiology of hyponatremia (HN during hospitalization in a neurointensive care unit following spontaneous intracerebral hemorrhage (sICH remains unknown. This was a retrospective analysis of consecutive patients admitted to Detroit Receiving Hospital for sICH between January 2006 and July 2009. All serum Na levels were recorded for patients during the ICU stay. HN was defined as Na <135 mmol/L. A total of 99 patients were analyzed with HN developing in 24% of sICH patients. Patients with HN had an average sodium nadir of 130 ± 3 mmol/L and an average time from admission to sodium <135 mmol/L of 3.9 ± 5.7 days. The most common cause of hyponatremia was syndrome of inappropriate antidiuretic hormone (90% of HN patients. Patients with HN were more likely to have fever (50% vs. 23%; p = 0.01, infection (58% vs. 28%; p = 0.007 as well as a longer hospital length of stay (14 (8–25 vs. 6 (3–9 days; p < 0.001. Of the patients who developed HN, fifteen (62.5% patients developed HN in the first week following sICH. This shows HN has a fairly high incidence following sICH. The presence of HN is associated with longer hospital length of stays and higher rates of patient complications, which may result in worse patient outcomes. Further study is necessary to characterize the clinical relevance and treatment of HN in this population.

  18. Subarachnoid hemorrhage as a psychological trauma.

    Hütter, Bernd-Otto; Kreitschmann-Andermahr, Ilonka

    2014-04-01

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

  19. Ultraearly hematoma growth in active intracerebral hemorrhage

    2016-01-01

    Objective: To determine the association of ultraearly hematoma growth (uHG) with the CT angiography (CTA) spot sign, hematoma expansion, and clinical outcomes in patients with acute intracerebral hemorrhage (ICH). Methods: We analyzed data from 231 patients enrolled in the multicenter Predicting Haematoma Growth and Outcome in Intracerebral Haemorrhage Using Contrast Bolus CT study. uHG was defined as baseline ICH volume/onset-to-CT time (mL/h). The spot sign was used as marker of active hemorrhage. Outcome parameters included significant hematoma expansion (>33% or >6 mL, primary outcome), rate of hematoma expansion, early neurologic deterioration, 90-day mortality, and poor outcome. Results: uHG was higher in spot sign patients (p 4.7 mL/h (p = 0.002) and the CTA spot sign (p = 0.030) showed effects on rate of hematoma expansion but not its interaction (2-way analysis of variance, p = 0.477). uHG >4.7 mL/h improved the sensitivity of the spot sign in the prediction of significant hematoma expansion (73.9% vs 46.4%), early neurologic deterioration (67.6% vs 35.3%), 90-day mortality (81.6% vs 44.9%), and poor outcome (72.8% vs 29.8%), respectively. uHG was independently related to significant hematoma expansion (odds ratio 1.06, 95% confidence interval 1.03–1.10) and clinical outcomes. Conclusions: uHG is a useful predictor of hematoma expansion and poor clinical outcomes in patients with acute ICH. The combination of high uHG and the spot sign is associated with a higher rate of hematoma expansion, highlighting the need for very fast treatment in ICH patients. PMID:27343067

  20. [Emerging diseases. Crimean-Congo hemorrhagic fever].

    Kuljić-Kapulica, Nada

    2004-01-01

    Recognized for many years in central Asia and Eastern Europe, Crimean-Congo hemorrhagic fever (CCHF) is a severe zoonotic disease which affects people coming into contact with livestock or ticks. The range of the CCHF virus is now known to extend form central Asia to India, Pakistan, Afghanistan, Iran, Iraq, the Middle East, Eastern Europe, and to most of Saharan and sub-Saharan Africa. CCHF virus is a member of the Bunyavirus family, and is classified as a Nairovirus. After an incubation period of approximately 3 to 6 days the abrupt onset of acute febrile illness occurs. The first symptoms are similar to severe influenza and include fever, headache, severe back and abdominal pain. The hemorrhagic fever manifestations occur after several days of illnesses and include petechial rash, ecchymoses, hematemmesis, and melenna. Cases typically present with some form of hepatitis. The mortality rate is 10-50% in different outbreaks with deaths typically occurring during the second week of illness. The genus Hyalomma of ixodid ticks is the most important vector of the CCHF virus. Vertebrates including birds and small animals provide excellent amplifier hosts of both the virus and the tick. The virus can be transmitted to humans by direct contact with infected animals and from person to person. Early diagnosis is possible in special laboratories using antigen detection by imunofluorescence or ELISA tests or molecular methods as PCR and antibody detection. Tick control measures need to be emphasized and utilized to prevent CCHF. This includes spraying camp sites, clothing and danger areas with acaricides or repellent. Strict isolation of patients with CCHF and a focus on barrier nursing would help to prevent nosocomial spread. Presently the vaccine is a dangerous mouse brain-derived version. Future development of a vaccine would help to prevent human infection.

  1. Statins and risk of poststroke hemorrhagic complications

    MacIsaac, Rachael L.; Abdul-Rahim, Azmil H.; Siegerink, Bob; Bath, Philip M.; Endres, Matthias; Lees, Kennedy R.; Nolte, Christian H.

    2016-01-01

    Objective: To assess whether statin treatment before or after acute ischemic stroke (AIS) affects the risk of acute intracerebral hemorrhage (ICH), postacute ICH, and mortality within 90 days. Methods: Data were sought from the Virtual International Stroke Trials Archive, an international repository of clinical trials data. Using propensity score matching, we retrospectively compared patients with prior statin treatment and newly initiated statin within 3 days after AIS to patients without statin exposure. Outcomes of interest were acute symptomatic ICH (sICH), any acute ICH, postacute ICH, and mortality during follow-up of 3 months. Results: A total of 8,535 patients (mean age 70 years, 54% male, median baseline NIH Stroke Scale score 13) were analyzed. After propensity score matching, prior statin use was not strongly associated with sICH (adjusted odds ratio [OR] 1.33, 95% confidence interval [CI] 0.83–2.14) or any ICH (adjusted OR 1.35, 95% CI 0.92–1.98). There was no evidence of an interaction between prior statin use and thrombolysis. New initiation of statins was not associated with postacute ICH (adjusted hazard ratio [HR] 1.60, 95% CI 0.70–3.65). There was a signal towards lower 90-day mortality in patients with prior statin use (adjusted HR 0.84, 95% CI 0.70–1.00) and especially early initiation of statins (adjusted HR 0.67, 95% CI 0.46–0.97). Conclusions: Statin use prior to AIS was not associated with early hemorrhagic complications, irrespective of treatment with thrombolysis. New initiation of statin treatment early after AIS did not affect risk of postacute ICH, but might be associated with reduced mortality. PMID:27016519

  2. [Limits of hemodilution in the treatment of hemorrhagic shock].

    Caloghera, C; Mogoseanu, A; Stefănescu, G; Bordos, D

    1975-01-01

    Clinical analysis of 168 cases of hemorrhagic shock of the 230 cases of hemorrhage and injuries admitted to the 2nd Surgical Clinic of Timisora between 1970 and 1973, showed that the administration of blood substitutes (crystalloid and colloid solutions) may be extended with good results in the management of hemorrhagic shock up to a hematocrit of 20%, respectively 7 g Hb. This treatment implies a careful selection of the cases, based upon objective criteria (listed in the text), so that the none administration of blood should not involve any risks. Even in the cases in which blood tranfusion is indispensable, hemodilution reduces to a great extent the amount of blood required.

    Weiner, Gregory M; Grandhi, Ramesh; Zwagerman, Nathan T; Agarwal, Nitin; Friedlander, Robert M

    2015-02-01

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

    We report a case of cerebral hemorrhagic infarction after radiation for pituitary adenoma. A 55-year-old woman was hospitalized to check for aldosteronism, post-operative pituitary function, and recurrence of thyroid cancer. She had short-term memory disturbance beginning two months prior to admission. Brain MRI showed a T1 and T2 high intensity lesion of her left anterolateral thalamus. Brain MRA revealed a narrowing in her left middle cerebral artery. The abnormal brain lesion was diagnosed as cerebral hemorrhagic infarction. She had received radiation therapy for pituitary adenoma 20 years earlier. It was considered that her cerebral hemorrhagic infarction was caused by radiation therapy. (author)

  6. Fetal-Maternal Hemorrhage: A Case and Literature Review

    Nino Solomonia

    2012-11-01

    Full Text Available Nearly all pregnancies include an insignificant hemorrhage of fetal blood into the maternal circulation. In some cases, the hemorrhage is large enough to compromise the fetus, resulting in fetal demise, stillbirth, or delivery of a severely anemic infant. Unfortunately, the symptoms of a significant fetal-maternal hemorrhage can be subtle, nonspecific, and difficult to identify at the time of the event. We present the case of a severely anemic newborn who was delivered in our facility with an extensive literature review.

  10. Management of hemorrhage in gastrointestinal stromal tumors: a review.

    Liu, Qi; Kong, Fanmin; Zhou, Jianping; Dong, Ming; Dong, Qi

    2018-01-01

    Gastrointestinal stromal tumors (GISTs) are relatively common mesenchymal tumors. They originate from the wall of hollow viscera and may be found in any part of the digestive tract. The prognosis of patients with stromal tumors depends on various risk factors, including size, location, presence of mitotic figures, and tumor rupture. Emergency surgery is often required for stromal tumors with hemorrhage. The current literature suggests that stromal tumor hemorrhage indicates poor prognosis. Although the optimal treatment options for hemorrhagic GISTs are based on surgical experience, there remains controversy with regard to optimum postoperative management as well as the classification of malignant potential. This article reviews the biological characteristics, diagnostic features, prognostic factors, treatment, and postoperative management of GISTs with hemorrhage.

    2009-01-01

    Full Text Available Stroke, though rare in children is among the top 10 causes of death in childhood. Incidence of ischemic and hemorrhagic stroke is the same in children .We report a case of hemorrhagic stroke in a two year old girl who presented with a limp, inability to stand on the left leg and left hemiparesia. Her complaint began 10 days ago after a bout of left clonic seizure. She had been admitted to the hospital for a week due to delayed hemorrhage of the umbilical stump at the age of 18 days. Brain CT scan showed a round, hyper dense area with mass effect in the right supraparietal region. Craniotomy revealed a hemorrhage and report of pathology was hematoma. Considering the delayed umbilical cord bleeding and normality of usual tests for hemostasis and partial deficiency of factor XIII in both parents, the problem was diagnosed as homozygote severe deficiency of factor XIII.

  18. Data Hemorrhages in the Health-Care Sector

    Johnson, M. Eric

    Confidential data hemorrhaging from health-care providers pose financial risks to firms and medical risks to patients. We examine the consequences of data hemorrhages including privacy violations, medical fraud, financial identity theft, and medical identity theft. We also examine the types and sources of data hemorrhages, focusing on inadvertent disclosures. Through an analysis of leaked files, we examine data hemorrhages stemming from inadvertent disclosures on internet-based file sharing networks. We characterize the security risk for a group of health-care organizations using a direct analysis of leaked files. These files contained highly sensitive medical and personal information that could be maliciously exploited by criminals seeking to commit medical and financial identity theft. We also present evidence of the threat by examining user-issued searches. Our analysis demonstrates both the substantial threat and vulnerability for the health-care sector and the unique complexity exhibited by the US health-care system.

  19. Intracerebral hemorrhage auto recognition in computed tomography images

    Choi, Seok Yoon; Kang, Se Sik; Kim, Chang Soo; Kim, Jung Hoon; Kim, Dong Hyun; Ye, Soo Young; Ko, Seong Jin

    2013-01-01

    The CT examination sometimes fail to localize the cerebral hemorrhage part depending on the seriousness and may embarrass the pathologist if he/she is not trained enough for emergencies. Therefore, an assisting role is necessary for examination, automatic and quick detection of the cerebral hemorrhage part, and supply of the quantitative information in emergencies. the computer based automatic detection and recognition system may be of a great service to the bleeding part detection. As a result of this research, we succeeded not only in automatic detection of the cerebral hemorrhage part by grafting threshold value handling, morphological operation, and roundness calculation onto the bleeding part but also in development of the PCA based classifier to screen any wrong choice in the detection candidate group. We think if we apply the new developed system to the cerebral hemorrhage patient in his critical condition, it will be very valuable data to the medical team for operation planning

  20. Sequential changes of sodium magnetic resonance images after cerebral hemorrhage

    Shimizu, T.; Naritomi, H.; Kuriyama, Y.; Sawada, T.

    1992-01-01

    Four patients with cerebral hemorrhage were examined serially from the acute to chronic phase by 1 H magnetic resonance imaging (MRI), 23 Na MRI and computed tomography (CT). At 1-2 days after bleeding, the 23 Na image revealed no visible signal change in the area of hemorrhage, although CT and 1 H images clearly demonstrated the existence of a hematoma in the thalamus or putamen. At 4-7 days after the hemorrhage, the 23 Na images began to exhibit a small increase in signal intensity at the hematoma site, while at 2-3 weeks, a marked increase in 23 Na signal intensity was observed. These findings suggest that the hematoma consisted mainly of a corpuscular component, with a low Na + concentration, with little serum component. 23 Na MRI appears to provide important information for understanding the evoluation of cerebral hemorrhage and for estimating the viability of cells, although its value for diagnosis may not be great.

  3. Associations of outdoor air pollution with hemorrhagic stroke mortality.

    Yorifuji, Takashi; Kawachi, Ichiro; Sakamoto, Tetsuro; Doi, Hiroyuki

    2011-02-01

    Evidence linking short-term exposure to outdoor air pollution with hemorrhagic stroke is inconsistent. We evaluated the associations between outdoor air pollution and specific types of stroke in Tokyo, Japan, from April 2003 to December 2008. We obtained daily counts of stroke mortality (n = 41,440) and concentrations of nitrogen dioxide as well as particles less than 2.5 μm in diameter. Time-series analysis was employed. Although same-day air pollutants were positively associated with ischemic stroke and intracerebral hemorrhage mortality, both air pollutants were more strongly associated with subarachnoid hemorrhage mortality: rate ratio was 1.041 (95% confidence interval: 1.011-1.072) for each 10 μg/m3 increase in the previous-day particles less than 2.5 μm. This study suggests that short-term exposure to outdoor air pollution increases the risks of hemorrhagic stroke mortality as well as ischemic stroke mortality.

  4. Characteristics of Hemorrhagic Stroke following Spine and Joint Surgeries.

    Yang, Fei; Zhao, Jianning; Xu, Haidong

    2017-01-01

    Hemorrhagic stroke can occur after spine and joint surgeries such as laminectomy, lumbar spinal fusion, tumor resection, and total joint arthroplasty. Although this kind of stroke rarely happens, it may cause severe consequences and high mortality rates. Typical clinical symptoms of hemorrhagic stroke after spine and joint surgeries include headache, vomiting, consciousness disturbance, and mental disorders. It can happen several hours after surgeries. Most bleeding sites are located in cerebellar hemisphere and temporal lobe. A cerebrospinal fluid (CSF) leakage caused by surgeries may be the key to intracranial hemorrhages happening. Early diagnosis and treatments are very important for patients to prevent the further progression of intracranial hemorrhages. Several patients need a hematoma evacuation and their prognosis is not optimistic.

  8. Acute hemorrhagic edema of infancy: report of three cases.

    Emerich, Paulo Sergio; Prebianchi, Patricia Almeida; Motta, Luciene Lage da; Lucas, Elton Almeida; Ferreira, Leonardo Mello

    2011-01-01

    Acute Hemorrhagic Edema of Infancy is an infrequent leukocytoclastic vasculitis which occurs almost exclusively in children between 4 months and 2 years of age. It is clinically characterized by the triad fever, purpuric lesions on the face, auricular pinna and extremities, and edema. Although the cutaneous findings are dramatic and of rapid onset, the prognosis is favorable, with spontaneous resolution within 1 to 3 weeks. Three cases are described in which clinical and histopathological findings are characteristic of acute hemorrhagic edema of infancy.

  11. A Study of Renogram in Korean Hemorrhagic Fever

    Choi, Tae Kyu; Lee, Jung Sang; Koh, Chang Soon; Lee, Mun Ho

    1974-01-01

    The patterns of renogram in patients with Korean hemorrhagic fever were evaluated with clinical course and renal hemodynamic changes in various clinical stages. The renal plasma flow was measured by hippuran blood clearance using 131 I-ortho-iodohippurate and hippuran renogram was analysed means of quantitative and qualitative methods in 26 patients of Korean hemorrhagic fever. The results obtained with this study were as follows;1) During the oliguric phase of Korean hemorrhagic fever, the renogram showed non-functioning (flat) or obstructive pattern. The group of patients with non-functioning pattern of renogram had more severe impairment of renal function and grave prognosis than the group with obstructive pattern of renogram. 2) During the diuretic phase, the renogram showed obstructive or dysfunction ar normal pattern, which was related with the recovery of renal function. Obstruction pattern of renogram was observed till the 2nd week of diuretic phase. Normal pattern of renogram began to appear by the 2nd week of diuretic phase. 3) During the convalescent phase of Korean hemorrhagic fever, 40% of patients showed dysfunction pattern of renogram, and the recovery of abnormal renogram in Korean hemorrhagic fever was more delayed than the recovery of clinical features and laboratory findings. 4) The renogram showed normal pattern 6 months after onset of Korean hemorrhagic fever in all cases. 5) There was significant correlationship between the pattern of renogram and the decrease of renal plasma flow in the patients with Korean hemorrhagic fever. The decrease of renal plasma flow was marked in the patients with non-functioning pattern of renogram and was least in the patients with dysfunction pattern of renogram. All above results suggested that the renogram reflects the effective renal plasma flow and degree of renal impairment, and the renogram may be one of the important indexes which could give us a more precise prognosis in Korean hemorrhagic fever.

  12. Possible sexual transmission of Crimean-Congo hemorrhagic fever

    Full Text Available Three cases of family transmission of laboratory-confirmed Crimean-Congo hemorrhagic fever (CCHF among spouses are reported. These spouses had sexual contact at the end of the incubation period or during the early stage of the mild form of CCHF, without any hemorrhagic symptoms in the first infected spouse. This report demonstrates that sexual contact may represent a real risk of CCHF transmission, even if the patient only experiences mild symptoms.

  13. Bilateral adrenal hemorrhage and primary antiphospholipid antibody syndrome

    Bilateral adrenal hemorrhage is an uncommon entity that is difficult to diagnose given the ambiquity of the clinical signs. Computerized tomography plays a major role in the diagnosis, disclosing enlarged adrenal glands presenting the hyperdense aspect that characterizes this disorders. We present a case of bilateral adrenal hemoorrhage in a patient diagnosed as having primary antiphospholipid antibody syndrome, which is a less common cause of adrenal hemorrhage than those classically reported, such as anticoagulant therapy, sepsis, shock and abdominal injury.

    We report neuroimaging findings of intracranial hemorrhage and cerebral edema in an infant with obtundation and seizures, initially suspected to be secondary to non-accidental trauma but finally attributed to hypernatremic dehydration. Neuroimaging findings due to hypernatremic dehydration have not been previously described in the radiologic literature. Hypernatremia should be included in the differential diagnosis of intracranial hemorrhage in the infant without evidence of nonaccidental trauma. (orig.). With 1 fig

  15. Predictors of acute symptomatic seizures after intracranial hemorrhage in infants.

    2014-10-01

    To determine the prevalence of acute symptomatic seizures in infants with supratentorial intracranial hemorrhage, to identify potential risk factors, and to determine the effect of acute seizures on long-term morbidity and mortality. Children less than 24 months with intracranial hemorrhage were identified from a neurocritical care database. All patients who received seizure prophylaxis beginning at admission were included in the study. Risk factors studied were gender, etiology, location of hemorrhage, seizure(s) on presentation, and the presence of parenchymal injury. Acute clinical and electrographic seizures were identified from hospital medical records. Subsequent development of late seizures was determined based on clinical information from patients' latest follow-up. Patients with idiopathic neonatal intracranial hemorrhage, premature infants, and those with prior history of seizures were excluded from analysis. Seventy-two infants met inclusion criteria. None. Forty percent of infants had acute symptomatic seizures. The prevalence was similar regardless of whether etiology of hemorrhage was traumatic or nontraumatic. Seizures on presentation and parenchymal injury were independent risk factors of acute seizures (p = 0.001 and p = 0.006, respectively). Younger children and women were also at higher risk (p Acute seizures were not predictive of mortality, but nearly twice as many patients with acute seizures developed late seizures when compared with those without. Electrographic seizures and parenchymal injury were also predictive of development of late seizures (p hemorrhage are at high risk for acute symptomatic seizures. This is regardless of the etiology of hemorrhage. Younger patients, women, patients with parenchymal injury, and patients presenting with seizure are most likely to develop acute seizures. Although the benefits of seizure prophylaxis have not been studied in this specific population, these results suggest that it is an important component

  18. Spontaneous Intracerebral Hemorrhage: Computed Tomographic Characteristics and Outcome

    Aimara de la Caridad Vergara Santos

    2015-12-01

    Full Text Available Background: strokes are the third leading cause of death among adults and 10-15 % of them are due to spontaneous intracerebral hemorrhage. Objective: to characterize spontaneous intracerebral hemorrhage through computed tomography scan and its outcome. Methods: a case series study was conducted comprising patients diagnosed with spontaneous intracerebral hemorrhage admitted to the Arnaldo Milián Castro Provincial University Hospital in Villa Clara from January 2009 to January 2010. Tomographic variables of interest were derived from evaluation of spontaneous intracerebral hematomas. Results: fifty-nine cases of spontaneous intracerebral hemorrhage were studied, 23 were located in lobar regions, 4 had severe midline shift, and 2 showed volume greater than 80 ml. Eight out of eleven with extension into the ventricular system had an unfavorable outcome. Among those with thalamic hemorrhage, patients with diameter larger than 4cm and extension into the ventricular system died. Patients with putaminal hemorrhage larger than 4 cm and posterior fossa hematoma with hydrocephalus had a poor outcome, as well as most individuals (55 with other mass effects. Most lobar hematomas (14 out of 23 had a satisfactory outcome, unlike cerebellar and brainstem hematomas. Conclusions: tomographic variables that had a negative impact on the outcome were: volume greater than 80 ml, severe midline shift, diameter larger than 4 cm, extension into the ventricular system, hydrocephalus, other signs of mass effect and brainstem location.

  19. Gastrointestinal Hemorrhage Related to Fluoxetine in a Patient With Stroke.

    Wee, Tze Chao

    2017-11-01

    We report on a patient who developed massive gastrointestinal hemorrhage related to the use of fluoxetine in combination with aspirin and clopidogrel. A 58-year-old man was admitted with a posterior circulation infarct with significant weakness in all four limbs and dysarthria. Aspirin and clopidogrel were started. Fluoxetine was started for pharmacological neurostimulation to promote motor recovery and for low mood. He developed gastrointestinal hemorrhage a week after fluoxetine was started. Fluoxetine was suspended and investigations failed to reveal the source of the bleeding. He was then restarted on fluoxetine along with dual antiplatelets, and gastrointestinal hemorrhage recurred after 1 week. He was extensively investigated for a source of gastrointestinal hemorrhage, and again no source could be identified. Eventually, fluoxetine was switched to mirtazapine with no further gastrointestinal hemorrhage. He remained on dual antiplatelets. A number of case-control and cohort studies had identified the association of gastrointestinal hemorrhage with the use of selective serotonin reuptake inhibitor (SSRI). We hope to raise awareness of this association in physical medicine and rehabilitation physicians as the use of SSRI is expected to rise.

  20. [A case of Churg-Strauss syndrome with subarachnoid hemorrhage].

    Ito, Miiko; Kato, Naoki; Su, Ching-Chan; Kayama, Takamasa

    2014-03-01

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

  1. Radiological analysis of subarachnoid hemorrhage from ruptured intracranial aneurysms

    Lee, Jong Doo; Suh, Jung Ho; Kim, Dong Ik

    1988-01-01

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

    Matsuyama, Toshitake; Tsukamoto, Naoki; Sugimori, Hajime; Yoshino, Teruo; Kashiwamura, Masamichi.

    1979-01-01

    The relationship among the incidence, the time of occurrence, and radiation dose was studied in regard to hemorrhagic cystitis after radiotherapy for carcinoma of the cervix uteri. Of 1004 patients with carcinoma of the cervix uteri observed between 1961 and 1974, 28 (2.8%) had bladder hemorrhage seemingly due to radiation injury (0.7% were serious). Incidences varied every year. The radiation dose was increased from 4000 to 6000 rad after 1971. In addition to this external dose, because the depth-dose has also increased, the rate of bladder hemorrhage has become high. Seven patients with serious bladder hemorrhage were exposed to more than 5000 rad of 60 Co. Bladder hemorrhage occurred comparatively frequently in patients in whom two hila were irradiated. It usually occurred a few years after irradiation (about 1 year after initial rectal hemorrhage). It continued for approximately 1 year in 21 patients, for approximately 3 years in 4 patients, and for approximately 4 years in 3 patients. Adrenochrome (a hemostatic agent) and antiplasmin were used as therapeutic agents. Serious patients improved remarkably when a large amount of diluted formaline solution or conjugated estrogen was administered intravenously. (Namekawa, K.)

    Nadarajah, Jeyaseelan; Madhusudhan, Kumble Seetharama; Yadav, Ajay Kumar; Gupta, Arun Kumar; Vikram, Naval Kumar

    2015-01-01

    Dengue is a common viral infection worldwide with presentation varying from clinically silent infection to dengue fever, dengue hemorrhagic fever, and severe fulminant dengue shock syndrome. Neurological manifestation usually results from multisystem dysfunction secondary to vascular leak. Presentation as hemorrhagic encephalitis is very rare. Here we present the case of a 13-year-old female admitted with generalized tonic clonic seizures. Plain computed tomography (CT) scan of head revealed hypodensities in bilateral deep gray matter nuclei and right posterior parietal lobe without any hemorrhage. Cerebrospinal fluid (CSF) and serology were positive for IgM and IgG antibodies to dengue viral antigen. Contrast-enhanced magnetic resonance imaging (MRI) revealed multifocal T2 and fluid attenuated inversion recovery (FLAIR) hyperintensities in bilateral cerebral parenchyma including basal ganglia. No hemorrhage was seen. She was managed with steroids. As her clinical condition deteriorated, after being stable for 2 days, repeat MRI was done which revealed development of hemorrhage within the lesions, and diagnosis of acute hemorrhagic encephalitis of dengue viral etiology was made

    Full Text Available Aim: The aim of this study is to identify antibiogram and heavy metal resistance pattern of Aeromonas hydrophila and Edwardsiella tarda isolated from red hybrid tilapia (Oreochromis spp. coinfected with motile aeromonas septicemia and edwardsiellosis in four commercial fish farms. Materials and Methods: A. hydrophila and E. tarda were isolated using glutamate starch phenol red and xylose lysine deoxycholate (Merck, Germany as a selective medium, respectively. All the suspected bacterial colonies were identified using conventional biochemical tests and commercial identification kit (BBL Crystal, USA. Susceptibility testing of present bacterial isolates to 16 types of antibiotics (nalidixic acid, oxolinic acid, compound sulfonamides, doxycycline, tetracycline, novobiocin, chloramphenicol, kanamycin, sulfamethoxazole, flumequine, erythromycin, ampicillin, spiramycin, oxytetracycline, amoxicillin, and fosfomycin and four types of heavy metals (mercury, chromium, copper, and zinc were carried out using disk diffusion and two-fold agar dilution method, respectively. Results: Three hundred isolates of A. hydrophila and E. tarda were successfully identified by biochemical tests. Antibiotic susceptibility testing results showed that 42.2% of the bacterial isolates were sensitive to compound sulfonamides, sulfamethoxazole, flumequine, oxytetracycline, doxycycline, and oxolinic acid. On the other hand, 41.6% of these isolates were resistant to novobiocin, ampicillin, spiramycin, and chloramphenicol, which resulted for multiple antibiotic resistance index values 0.416. Among tested heavy metals, bacterial isolates exhibited resistant pattern of Zn2+ > Cr6+ > Cu2+ > Hg2+. Conclusion: Results from this study indicated that A. hydrophila and E. tarda isolated from coinfected farmed red hybrid tilapia were multi-resistant to antibiotics and heavy metals. These resistant profiles could be useful information to fish farmers to avoid unnecessary use of

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

    Walter, Johannes; Unterberg, Andreas W; Zweckberger, Klaus

    2018-05-01

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

    2015-01-01

    To report the outcomes of vitreous hemorrhage (VH) associated with hemorrhagic polypoidal choroidal vasculopathy (PCV). A retrospective study of 28 eyes of 27 consecutive patients of hemorrhagic PCV with VH, which were managed surgically between January 2003 and December 2011, was performed. All patients underwent pars plana vitrectomy for VH associated with PCV. The main outcome measure was best-corrected visual acuity (BCVA) at baseline, at 1, 3 and 6 months post operatively and at last follow up. The visual acuity measured on early treatment diabetic retinopathy study (ETDRS) chart improved in 16 eyes (57.1 %) by two or more lines, remained unchanged in nine eyes (32.1 %) and decreased in three (10.7 %) after surgery when compared to baseline VA. The mean baseline VA was 2.69 ± 0.57 logMAR units (hemorrhagic PCV have sustained improvement in visual acuity following surgery.

  7. Advances in the management of intracerebral hemorrhage.

    Kuramatsu, J B; Huttner, H B; Schwab, S

    2013-09-01

    Intracerebral hemorrhage (ICH) is one of the most detrimental sub-types of stroke and accounts for 10-15% of all strokes Qureshi et al. (Lancet 373(9675):1632-1644, 2009). ICH has an incidence of 10-30 cases per 100,000 people/year which is increasing and expected to double by the year 2050 Qureshi et al. (N Engl J Med 344 (19):1450-1460, 2001). Mortality rates still remain poor (30-50%) and functional dependency after ICH is high (~75%) van Asch et al. (Lancet Neurol 9 (2):167-176, 2010). Up to now, all randomized controlled trials investigating treatment approaches in ICH have failed to document improvements on clinical endpoints Mayer et al. (N Engl J Med 358 (20):2127-2137, 2008); Brouwers and Goldstein (Neurotherapeutics 9 (1):87-98, 2012). Only a specialized treatment of severely injured patients at dedicated neuro intensive care units [NICU] has been shown to be beneficial Qureshi et al. (Lancet 373(9675):1632-1644, 2009); Suarez et al. (Crit Care Med 32 (11):2311-2317, 2004). Currently, ongoing trials are investigating aggressive blood pressure lowering, hemostatic therapies, different operative strategies, intraventricular thrombolysis as well as neuroprotective approaches, and brain edema therapies. This review will summarize advanced treatment strategies and novel approaches which are currently under investigation.

    Before the introduction of computerized tomography (CT) there were some cases of intracerebral bleeding who were wrongly diagnosed as hypertensive encephalopathy or senile psychosis. We here report 5 cases who did not show any sign of motor paralysis. The clinical aspects of these cases were nausea and vomiting with dizziness (case 1), nausea and vomiting with slight headache (case 2), agnosia of left side with several kinds of disorientation (case 3), nausea and vomiting (case 4), and visual disturbance of right, lower quadrant (case 5). All of these cases showed no motor paralysis or abnormal reflex activities. By examination with CT each of them exhibited a high density area in the subcortical area of the right parietal lobe, the subcortical area of the right occipital lobe, the right temporal and parietal lobe, rather small portion of the left putamen and external capsule, and the subcortical area of left occipital lobe, respectively. Patients of cerebral hemorrhage without motor or sensory disturbances might often be taken for some psychic abnormality. We here have emphasized the importance of CT in such a group of patients. But for this technique, most of them would not be given adequate treatment and might be exposed to lifethreatening situations. (author)

  9. Autologous Blood Transfusion for Postpartum Hemorrhage.

    Greenawalt, Julia A; Zernell, Denise

    Postpartum hemorrhage (PPH) is a leading contributor to maternal morbidity and mortality in the United States and globally. Although the rate of PPH is generally decreasing nationally, severity of PPH appears to be increasing, potentially related to the various comorbidities associated with women of childbearing age. There is increasing evidence of risks associated with allogeneic blood transfusion, which has historically been the classic therapeutic approach for treatment to PPH. Pregnant women are particularly susceptible to the implications of sensitization to red cell antigens, a common sequela to allogenic blood transfusion. Autologous blood transfusion eliminates the potential of communicable disease transmission as well as the conceivable threat of a blood transfusion reaction. Recent technological advances allow cell salvage coupled with the use of a leukocyte filter to be used as an alternative approach for improving the outcome for women experiencing a PPH. Modest changes in standard operating procedure and continued training in use and application of cell salvaged blood may assist in minimizing negative outcomes from PPH. Salvaged blood has been demonstrated to be at least equal and often superior to banked blood. We discuss nursing implications for application of this technology for women with PPH. Continued research is warranted to evaluate the impact that application of cell salvage with filtration has on the patient experiencing a PPH.

  10. Hematoma Expansion Following Acute Intracerebral Hemorrhage

    Brouwers, H. Bart; Greenberg, Steven M.

    2013-01-01

    Intracerebral hemorrhage, the most devastating form of stroke, has no specific therapy proven to improve outcome by randomized controlled trial. Location and baseline hematoma volume are strong predictors of mortality, but are non-modifiable by the time of diagnosis. Expansion of the initial hematoma is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for hematoma expansion have been identified, including baseline ICH volume, early presentation after symptom onset, anticoagulation, and the CT angiography spot sign. Although the biological mechanisms of hematoma expansion remain unclear, accumulating evidence supports a model of ongoing secondary bleeding from ruptured adjacent vessels surrounding the initial bleeding site. Several large clinical trials testing therapies aimed at preventing hematoma expansion are in progress, including aggressive blood pressure reduction, treatment with recombinant factor VIIa guided by CT angiography findings, and surgical intervention for superficial hematomas without intraventricular extension. Hematoma expansion is so far the only marker of outcome that is amenable to treatment and thus a potentially important therapeutic target. PMID:23466430

    Smoothed Particle Hydrodynamics (SPH) is adapted to simulate hemorrhage in the injured human body. As a Lagrangian fluid simulation, SPH uses fluid particles as computational elements and thus mass conservation is trivially satisfied. In order to ensure anatomical fidelity, a three-dimensional reconstruction of a portion of the human body -here, demonstrated on the lower leg- is sampled as skin, bone and internal tissue particles from the CT scan image of an actual patient. The injured geometry is then generated by simulation of ballistic projectiles passing through the anatomical model with the Material Point Method (MPM) and injured vessel segments are identified. From each such injured segment, SPH is used to simulate bleeding, with inflow boundary condition obtained from a coupled 1-d vascular tree model. Blood particles interact with impermeable bone and skin particles through the Navier-Stokes equations and with permeable internal tissue particles through the Brinkman equations. The SPH results are rendered in post-processing for improved visual fidelity. The overall simulation strategy is demonstrated on several injury scenarios in the lower leg.

    1996-01-01

    Two myxoma virus-rabbit hemorrhagic disease virus (RHDV) recombinant viruses were constructed with the SG33 strain of myxoma virus to protect rabbits against myxomatosis and rabbit viral hemorrhagic disease. These recombinant viruses expressed the RHDV capsid protein (VP60). The recombinant protein, which is 60 kDa in size, was antigenic, as revealed by its reaction in immunoprecipitation with antibodies raised against RHDV. Both recombinant viruses induced high levels of RHDV- and myxoma vir...

    Germinal matrix hemorrhage (GMH) is the most common neurological disease of premature newborns. GMH causes neurological sequelae such as cerebral palsy, post-hemorrhagic hydrocephalus, and mental retardation. Despite this, there is no standardized animal model of spontaneous GMH using newborn rats to depict the condition. We asked whether stereotactic injection of collagenase type VII (0.3 U) into the ganglionic eminence of neonatal rats would reproduce the acute brain injury, gliosis, hydroc...

    The aim of this investigation was to determine the factors influencing acute intracerebral hemorrhage severity on admission and clinical outcomes at discharge. Sixty acute stroke hospitals throughout Japan participated in the Japan Standard Stroke Registry Study (JSSRS), documenting the in-hospital course of 16,630 consecutive patients with acute stroke from January 2001 to March 2004. We identified 2,840 adult patients from the JSSRS who had intracerebral hemorrhage. Intracerebral hemorrhage severity on admission was strongly related to age, previous stroke history, and hemorrhage size in a monotone fashion [chi(2)(9) = 374.5, p < 0.0001]. Drinking history was also predictive of intracerebral hemorrhage severity on admission, but the association was not monotone. Interestingly, intracerebral hemorrhage severity on admission was increased in nondrinking and heavy drinking compared to mild drinking (p < 0.05). Unsuccessful outcome (modified Rankin scale score = 3-6) was related to age, previous stroke history, hemorrhage size, and intracerebral hemorrhage severity on admission [chi(2)(9) = 830.4, p < 0.0001]. Mortality was related to hemorrhage size, intraventricular hemorrhage, intracerebral hemorrhage severity on admission, and surgical operation [chi(2)(7) = 540.4, p < 0.0001]. We could find four varied factors associated with intracerebral hemorrhage severity and its outcomes. Interestingly, intracerebral hemorrhage severity tended to be greater in nondrinking and heavy drinking than mild drinking. Additionally, surgical operation decreased intracerebral hemorrhage mortality. Copyright 2008 S. Karger AG, Basel.

  15. Intraventricular Hemorrhage and Post Hemorrhagic Hydrocephalus among Very-Low-Birth-Weight Infants in Korea.

    Ahn, So Yoon; Shim, So-Yeon; Sung, In Kyung

    2015-10-01

    Here, we aimed to evaluate the incidence and mortality of intraventricular hemorrhage (IVH) and post-hemorrhagic hydrocephalus (PHH) among very-low-birth-weight (VLBW) infants in Korea and assess the associated factors of PHH. This cohort study used prospectively collected data from the Korean Neonatal Network (KNN). Among 2,386 VLBW infants in the KNN database born between January 2013 and June 2014, 63 infants who died without brain ultrasonography results were excluded. Maternal demographics and neonatal clinical characteristics were assessed. The overall incidence of IVH in all the VLBW infants was 42.2% (987 of 2,323), while those of IVH grade 1, 2, 3, and 4 were 25.1%, 7.0%, 4.8%, and 5.5%, respectively. The incidence and severity of IVH showed a negatively correlating trend with gestational age and birth weight. PHH developed in 0%, 3.5%, 36.1%, and 63.8% of the surviving infants with IVH grades 1, 2, 3, and 4, respectively. Overall, in the VLBW infants, the IVH-associated mortality rate was 1.0% (24/2,323). Only IVH grade severity was proven to be an associated with PHH development in infants with IVH grades 3-4. This is the first Korean national report of IVH and PHH incidences in VLBW infants. Further risk factor analyses or quality improvement studies to reduce IVH are warranted.

  16. A literature review of the epidemiology of sepsis in Latin America Revisión bibliográfica de la distribución epidemiológica de la septicemia en América Latina

    Fabián Jaimes

    2005-09-01

    Full Text Available OBJECTIVES: Epidemiological studies from the United States of America and from Europe have shown that sepsis is a widely prevalent syndrome, with either steady or slightly decreasing rates of morbidity and of mortality in recent decades. The objective of this paper is to provide a systematic review regarding the description and characterization of sepsis in Latin America. METHODS: To locate materials on sepsis in Latin America, a comprehensive search strategy was employed with three medical bibliographic databases, using combinations of the terms "sepsis," "septicemia," "bacteremia," "sepsis syndrome," "epidemiology," "incidence," and "prevalence." The materials selected were in English, Spanish, or Portuguese. RESULTS: The titles of more than 1 000 potentially relevant articles were screened, and more than 600 selected abstracts were reviewed in detail. Twenty papers published from 1990 through 2004 were selected and analyzed. The studies described in the 20 articles were extremely heterogeneous in design, population, sample size, end points, and follow-up. The studies did not all apply the same clinical definition for sepsis, thus making it impossible to produce a precise overall estimate of the magnitude of the problem of sepsis in Latin America. CONCLUSIONS: The results of the literature review suggest that the clinical and epidemiological approaches to the problem of sepsis in Latin America have sometimes been inappropriate with respect to research design, study population, and clinical outcome. Further, some data suggest that in terms of both frequency and mortality the situation with sepsis and severe systemic infections may be worse in Latin America than it is in developed countries.OBJETIVOS: Algunos estudios epidemiológicos realizados en Estados Unidos de Amé-rica y en Europa han demostrado que la septicemia es un síndrome de muy amplia distribución cuya frecuencia ha permanecido estable o ha descendido ligeramente en los últimos

  17. [Marburg and Ebola hemorrhagic fevers--pathogens, epidemiology and therapy].

    Stock, Ingo

    2014-09-01

    Marburg and Ebola hemorrhagic fevers are severe, systemic viral diseases affecting humans and non-human primates. They are characterized by multiple symptoms such as hemorrhages, fever, headache, muscle and abdominal pain, chills, sore throat, nausea, vomiting and diarrhea. Elevated liver-associated enzyme levels and coagulopathy are also associated with these diseases. Marburg and Ebola hemorrhagic fevers are caused by (Lake victoria) Marburg virus and different species of Ebola viruses, respectively. They are enveloped, single-stranded RNA viruses and belong to the family of filoviridae. Case fatality rates of filovirus disease outbreaks are among the highest reported for any human pathogen, ranging from 25 to 90% or more. Outbreaks of Marburg and Ebola hemorrhagic fever occur in certain regions of equatorial Africa at irregular intervals. Since 2000, the number of outbreaks has increased. In 2014, the biggest outbreak of a filovirus-induced hemorrhagic fever that has been documented so far occurred from March to July 2014 in Guinea, Sierra Leone, Liberia and Nigeria. The outbreak was caused by a new variant of Zaire Ebola-Virus, affected more than 2600 people (stated 20 August) and was associated with case-fatality rates of up to 67% (Guinea). Treatment of Marburg and Ebola hemorrhagic fevers is symptomatic and supportive, licensed antiviral agents are currently not available. Recently, BCX4430, a promising synthetic adenosine analogue with high in vitro and in vivo activity against filoviruses and other RNA viruses, has been described. BCX4430 inhibits viral RNA polymerase activity and protects cynomolgus macaques from Marburg virus infection when administered as late as 48 hours after infection. Nucleic acid-based products, recombinant vaccines and antibodies appear to be less suitable for the treatment of Marburg and Ebola hemorrhagic fevers.

    The victim, 52 year old man, was thrust down and hit his left occiput against the concrete floor. He was hospitalised and his comatose state continued to the death. On admission, blood pressure was 212/110 mmHg and the computed tomography scan of the head showed only an extensive right subdural hematoma. But the intracerebral hemorrhages in the right frontal, temporal and parietal lobes were recognized 10.5 hours after the trauma. A subdural hematoma was evacuated by operation on the second hospital day. The intracerebellar hemorrhage also appeared 16 hours after the trauma. Blood pressure fluctuated between 160/80 and 200/110 mmHg. The photo of CT scan at 38.5 hours after the trauma showed little subdural hematoma and new intracerebral hemorrhage located in the left temporal lobe. On the third hospital day, he was equipped with a respirator and blood pressure was between 132/84 and 242/100 mmHg. The reaction of the pupils to light disappeared on the 8th hospital day. Blood pressure gradually decreased on the 9th and 10th hospital days and he died on the 11th day. Autopsy revealed a bruise in the left occiput, a linear fracture in the frontal and left parietal bones and a small amount of subdural hematoma on the surface of the right cerebral hemisphere. Cortical contusions were found in the right frontal, the both temporal and the left parietal lobes. Intracerebral hemorrhages were found in the right frontal, the both temporal and the right parietal lobes. Intracerebellar hemorrhage was also found. Cardiac hypertrophy and atherosclerosis of the aorta were recognized. We thought that small hemorrhages which were not clearly detectable by CT scan immediately after injury may have developed into massive intracerebral and intracerebellar hemorrhages due to high blood pressure after a hospitalization.

    Hospitalizations for pregnancy-related stroke are rare but increasing. Hemorrhagic stroke (HS), ie, subarachnoid hemorrhage and intracerebral hemorrhage, is more common than ischemic stroke in pregnant versus nonpregnant women, reflecting different phenotypes or risk factors. We compared stroke risk factors and outcomes in pregnant versus nonpregnant HS in the Get With The Guidelines-Stroke Registry. Using medical history or International Classification of Diseases-Ninth Revision codes, we identified 330 pregnant and 10 562 nonpregnant female patients aged 18 to 44 years with HS in Get With The Guidelines-Stroke (2008-2014). Differences in patient and care characteristics were compared by χ(2) or Fisher exact test (categorical variables) or Wilcoxon rank-sum (continuous variables) tests. Conditional logistic regression assessed the association of pregnancy with outcomes conditional on categorical age and further adjusted for patient and hospital characteristics. Pregnant versus nonpregnant HS patients were younger with fewer pre-existing stroke risk factors and medications. Pregnant versus nonpregnant subarachnoid hemorrhage patients were less impaired at arrival, and less than half met blood pressure criteria for severe preeclampsia. In-hospital mortality was lower in pregnant versus nonpregnant HS patients: adjusted odds ratios (95% CI) for subarachnoid hemorrhage 0.17 (0.06-0.45) and intracerebral hemorrhage 0.57 (0.34-0.94). Pregnant subarachnoid hemorrhage patients also had a higher likelihood of home discharge (2.60 [1.67-4.06]) and independent ambulation at discharge (2.40 [1.56-3.70]). Pregnant HS patients are younger and have fewer risk factors than their nonpregnant counterparts, and risk-adjusted in-hospital mortality is lower. Our findings suggest possible differences in underlying disease pathophysiology and challenges to identifying at-risk patients. © 2015 American Heart Association, Inc.

  20. A study of the intracranial hemorrhagic lesions by computed tomography

    Honda, Kazuyoshi

    1983-01-01

    Changes in X-ray density corresponding to intracranial hemorrhagic lesions were follwed in fourteen patients. In addition, X-ray density of solutions with oxyhemoglobin, CO-hemoglobin and methehemoglobin as well as suspension of blood corpuscles, hemolysate, calcium, sodium, iron, copper, magnesium and phosphate was measured. The following results were obtained: 1) The average X-ray density of hemorrhagic lesions within 48 hours after intracranial hemorrhage was 73.80 H.N.: 55.81 H.N. between 48 hours and three weeks : 49.5 H.N. between three and four weeks: 26.81 H.N. over four weeks. In all cases, the intracranial hemorrhage in its acute stage revealed a high X-ray density as compared to the surrounding cerebral tissue. This was helpful for the detection of hemorrhagic lesions. 2) X-ray density of the lesion decreased 1.68 H.N./day after the hemorrhage. 3) Among various constituents of blood, the solution of sodium showed the highest X-ray density, followed by hemoglobin, magnesium, calcium, phosphate, copper and iron. 4) However, when the concentration of each blood constituent was taken into consideration, hemoglobin showed the highest X-ray density, followed by calcium, copper, sodium, magnesium, phosphate and iron. 5) There was no significant difference in X-ray density between the suspension of blood corpuscles and hemolysate. The findings were the same whether hemoglobin was oxyhemoglobin, CO-hemoglobin or methehemoglobin. 6) Oxyhemoglobin showed the highest X-ray density, followed by CO-hemoglobin and methehemoglobin. These findings suggested that hemoglobin in the intracranial hemorrhagic lesion seems to be a major factor producing a high X-ray density particularly in its acute stage. (author)

  1. [Carbetocin use to prevent obstetric hemorrhage].

    Posadas Robledo, Francisco Javier

    2011-07-01

    in Mexico, obstetric hemorrhage and its complications are the second leading cause of maternal death and is the origin of irreversible functional consequences. Carbetocin is a synthetic analogue of oxytocin with an average lifespan four times that of oxytocin and pharmacological effects of 120 minutes produces a tonic contraction which reduces postpartum blood loss. To evaluate the usefulness of carbetocin to prevent uterine bleeding complications and maternal deaths and assess the benefits, effectiveness and side effects. Prospective, observational clinical research in two phases, the first from May 2005 to January 2006 with a sample of 40 patients and the second from January to December of 2008 with a sample of 72 patients conducted at the Hospital Materno Infantil Dr. Alberto López Hermosa, San Luis Potosi. All were high-risk pregnancies and medical complications that warranted specialty hospital management. The intervention consisted of applying undiluted single dose of 100 micrograms of intravenous carbetocin at the time of delivery, as prophylaxis in patients with uterine overdistention in the first phase of the study and complicated pregnancies in the second phase. Were born by caesarean section over 60%. Initially, the hemoglobin showed a reduction of 17% after delivery. Seven patients required blood transfusion (17.5%). In the second phase, 65 patients (90%) did not require transfusion, only 6 patients (8%) required transfusion. No side effects were documented. Uterine overdistension was the main risk factor for bleeding and transfusion. Carbetocin combines the safety of oxytocin and the strength of the ergonovine preparations. To determine where carbetocin will be situated in the future as an useful oxytocic, it requires more than a simple demonstration of its effectiveness. This should be determined in each clinical situation, with factors such as overdistended uterus, indicating the convenience and economic constraints.

  2. Vaccine Platforms to Control Arenaviral Hemorrhagic Fevers.

    Arenaviruses are rodent-borne emerging human pathogens. Diseases caused by these viruses, e.g., Lassa fever (LF) in West Africa and South American hemorrhagic fevers (HFs), are serious public health problems in endemic areas. We have employed replication-competent and replication-deficient strategies to design vaccine candidates potentially targeting different groups "at risk". Our leader LF vaccine candidate, the live reassortant vaccine ML29, is safe and efficacious in all tested animal models including non-human primates. In this study we showed that treatment of fatally infected animals with ML29 two days after Lassa virus (LASV) challenge protected 80% of the treated animals. In endemic areas, where most of the target population is poor and many live far from health care facilities, a single-dose vaccination with ML29 would be ideal solution. Once there is an outbreak, a fast-acting vaccine or post-exposure prophylaxis would be best. The 2(nd) vaccine technology is based on Yellow Fever (YF) 17D vaccine. We designed YF17D-based recombinant viruses expressing LASV glycoproteins (GP) and showed protective efficacy of these recombinants. In the current study we developed a novel technology to clone LASV nucleocapsid within YF17D C gene. Low immunogenicity and stability of foreign inserts must be addressed to design successful LASV/YFV bivalent vaccines to control LF and YF in overlapping endemic areas of West Africa. The 3(rd) platform is based on the new generation of alphavirus replicon virus-like-particle vectors (VLPV). Using this technology we designed VLPV expressing LASV GP with enhanced immunogenicity and bivalent VLPV expressing cross-reactive GP of Junin virus (JUNV) and Machupo virus (MACV), causative agents of Argentinian and Bolivian HF, respectively. A prime-boost regimen required for VLPV immunization might be practical for medical providers, military, lab personnel, and visitors in endemic areas.

  3. CT classification of small thalamic hemorrhages

    Kawahara, Nobutaka; Kaneko, Mitsuo; Tanaka, Keisei; Muraki, Masaaki; Sato, Kengo

    1984-01-01

    The thalamus is located deep in the cerebral hemispheres, and most of its nuclei have reciprocal fiber connections with specific areas over the cerebral cortex. Localized lesions in the thalamus, therefore, can cause specific neurological deficits, depending on their locations. From this point of view, we reviewed 110 cases, admitted over the past 7 years, with thalamic hemorrhages 37 (34%) of which were small hematomas less than 2 cm in diameter. These small hematomas could be divided into 4 types depending on their locations as follows: antero-lateral type, postero-lateral type, medial type, and dorsal type. Each type had the peculiar clinical features described below: 1) Postero-lateral Type (PL type, 28 cases, 76%): The original symptom was a sudden onset of moderate to severe sensori-motor deficits in most cases. The patients were mostly alert or only slightly confused. 2) Antero-lateral Type (AL type, 4 cases, 11%): The patients of this type first presented with sensori-motor disturbance and prefrontal signs. Both were generally mild and often disappeared early. 3) Medial Type (M type, 3 cases, 8%): The main symptom at onset was either a disturbance of consciousness or dementia. 4) Dorsal Type (D type, 2 cases, 5%): One patient with a right thalamic hematoma of this type showed geographical agnosia and visuo-constructive apraxia. The other patient, with a left-sided hematoma, exhibited transient clumsiness of the right hand and mild dysphasia. In our experience, the above classification of small hematomas clearly delineated the clinical symptoms and neurological signs of the different types; therefore, the symptoms and signs in larger hematoma could be explained by a combination of those of each type.

    2006-01-01

    Full text: Purpose: Despite the latest advances in medical treatment and neuro critical care, patients suffering spontaneous intracerebral hemorrhage (SICH) still have a very poor prognosis, with a greater mortality and larger neurological deficits at the survivors than for ischemic stroke. Many authors have shown that there are many mechanisms involved in the pathology of SICH: edema, ischemia, inflammation, apoptosis. All of these factors are affecting brain tissue surrounding hematoma and are responsible of the progressive neurological deterioration; most of these damages are not revealed by anatomical imaging techniques. The aim of our study was to asses the role of brain perfusion SPECT in demonstrating perfusion changes in SICH patients. Method: 17 SICH pts were studied. All pts underwent same day CT and brain SPECT with 99mTcHMPAO, 24h-5d from onset of stroke. Results: 14/17 pts showed a larger perfusion defect than expected after CT. In 2 pts hematoma diameter was comparable on CT and SPECT; 1pt had quasinormal aspect of SPECT study. In pts with larger defects, SPECT revealed a large cold spot with similar size compared with CT, and a surrounding hypo perfused area. 6/17 pts revealed cortical hyper perfusion adjacent to hypo perfused area and corresponding to a normal-appearing brain tissue on CT. In 3 pts we found crossed cerebellar diaskisis.In 2 pts we found cortical hypo perfused area in the contralateral cortex, with normal appearing brain tissue on CT. Conclusions: Brain perfusion SPECT revealed different types of perfusion changes in the brain tissue surrounding hematoma. These areas contain viable brain tissue that may be a target for future ne uroprotective strategies. Further studies are definitely required to demonstrate prognostic significance of these changes, but we can conclude that brain perfusion SPECT can play an important role in SICH, by early demonstrating functional changes responsible of clinical deterioration, thus allowing prompt

    Retinal hemorrhage is a well-recognized manifestation of child abuse found in many babies with shaken baby syndrome. The presence of retinal hemorrhage is generally associated with more severe neurological damage and a worse clinical outcome. MR imaging findings of retinal hemorrhages are not well described in the pediatric literature. We present a 6-month-old boy with new-onset seizures, subdural hemorrhage and bilateral retinal hemorrhages that were detected by MRI and confirmed by indirect ophthalmoscopy. This case demonstrates the MR imaging findings of retinal hemorrhages and the importance of radiologists being able to recognize these specific imaging features. (orig.)

    To evaluate the role of the α 1 -adrenergic system in the response to hemorrhage during development, lambs and adult sheep were chronically catheterized and hemorrhaged after pretreatment with prazosin or vehicle. The adults became markedly more hypotensive after α 1 -blockade and hemorrhage than after vehicle and hemorrhage, whereas the lambs were no more hypotensive when hemorrhaged after prazosin. In the adults and the lambs hemorrhage produced elevations in plasma renin activity and arginine vasopressin measured by radioimmunoassay. However, after prazosin, the adults had a far greater increase in arginine vasopressin levels than after vehicle treatment

  8. Quantitative estimation of hemorrhage in chronic subdural hematoma using the 51Cr erythrocyte labeling method

    Ito, H.; Yamamoto, S.; Saito, K.; Ikeda, K.; Hisada, K.

    1987-01-01

    Red cell survival studies using an infusion of chromium-51-labeled erythrocytes were performed to quantitatively estimate hemorrhage in the chronic subdural hematoma cavity of 50 patients. The amount of hemorrhage was determined during craniotomy. Between 6 and 24 hours after infusion of the labeled red cells, hemorrhage accounted for a mean of 6.7% of the hematoma content, indicating continuous or intermittent hemorrhage into the cavity. The clinical state of the patients and the density of the chronic subdural hematoma on computerized tomography scans were related to the amount of hemorrhage. Chronic subdural hematomas with a greater amount of hemorrhage frequently consisted of clots rather than fluid

    Full Text Available A 69-year-old man with chronic-phase chronic myeloid leukemia was initially treated with 100 mg dasatinib once a day. Despite a major molecular response within 9 months, he developed hemorrhagic colitis 32 months after starting dasatinib. Colonoscopy identified multiple hemorrhagic ulcers in the transverse colon. The pathological findings indicated cytomegalovirus infection. Dasatinib was stopped and he was started on ganciclovir. Three months later, colonoscopy confirmed the disappearance of the hemorrhagic ulcers. Dasatinib is a second-generation tyrosine kinase inhibitor used to treat chronic myeloid leukemia. As a multi-kinase inhibitor that acts on SRC-family kinases, its broader off-target kinase-inhibitory activity may account for the adverse events of dasatinib. Although gastrointestinal bleeding is common in patients taking dasatinib, the combination of cytomegalovirus infection and hemorrhagic colitis in the absence of systemic immunodeficiency is rare. Based on this case of dasatinibinduced hemorrhagic colitis with cytomegalovirus infection, we describe a possible mechanism and effective treatment.

    Ebola hemorrhagic fever (EHF) outbreaks occur sporadically in Africa and result in high rates of death. The 2000-2001 outbreak of Sudan virus-associated EHF in the Gulu district of Uganda led to 425 cases, of which 216 were laboratory confirmed, making it the largest EHF outbreak on record. Serum specimens from this outbreak had been preserved in liquid nitrogen from the time of collection and were available for analysis. Available samples were tested using a series of multiplex assays to measure the concentrations of 55 biomarkers. The data were analyzed to identify statistically significant associations between the tested biomarkers and hemorrhagic manifestations, viremia, and/or death. Death, hemorrhage, and viremia were independently associated with elevated levels of several chemokines and cytokines. Death and hemorrhage were associated with elevated thrombomodulin and ferritin levels. Hemorrhage was also associated with elevated levels of soluble intracellular adhesion molecule. Viremia was independently associated with elevated levels of tissue factor and tissue plasminogen activator. Finally, samples from nonfatal cases had higher levels of sCD40L. These novel associations provide a better understanding of EHF pathophysiology and a starting point for researching new potential targets for therapeutic interventions.

    Chronic subdural hematoma (CSDH) and symptomatic subdural hygroma are common diseases that require neurosurgical management. Burr hole trephination is the most popular surgical treatment for CSDH and subdural hygroma because of a low recurrence rate and low morbidity compared with craniotomy with membranectomy, and twist-drill craniotomy. Many reports suggest that placing a catheter in the subdural space for drainage can further reduce the rate of recurrence; however, complications associated with this type of drainage include acute subdural hematoma, cortical injury, and infection. Remote hemorrhage due to overdrainage of cerebrospinal fluid (CSF) is another possible complication of burr hole trephination with catheter drainage that has rarely been reported. Here, we present 2 cases of remote hemorrhages following burr hole trephination with catheter drainage for the treatment of CSDH and symptomatic subdural hygroma. One patient developed intracerebral hemorrhage and subarachnoid hemorrhage in the contralateral hemisphere, while another patient developed remote hemorrhage 3 days after the procedure due to the sudden drainage of a large amount of subdural fluid over a 24-hour period. These findings suggest that catheter drainage should be carefully monitored to avoid overdrainage of CSF after burr hole trephination.

    Accurate diagnosis of intracranial hemorrhage represents a frequent challenge for the practicing radiologist. The purpose of this article is to provide the reader with a synoptic overview of the imaging characteristics of intracranial hemorrhage, using text, tables, and figures to illustrate time-dependent changes. We examine the underlying physical, biological, and biochemical factors of evolving hematoma and correlate them with the aspect on cross-sectional imaging techniques. On CT scanning, the appearance of intracranial blood is determined by density changes which occur over time, reflecting clot formation, clot retraction, clot lysis and, eventually, tissue loss. However, MRI has become the technique of choice for assessing the age of an intracranial hemorrhage. On MRI the signal intensity of intracranial hemorrhage is much more complex and is influenced by multiple variables including: (a) age, location, and size of the lesion; (b) technical factors (e.g., sequence type and parameters, field strength); and (c) biological factors (e.g., pO2, arterial vs venous origin, tissue pH, protein concentration, presence of a blood-brain barrier, condition of the patient). We discuss the intrinsic magnetic properties of sequential hemoglobin degradation products. The differences in evolution between extra- and intracerebral hemorrhages are addressed and illustrated.

    Objective: To evaluate urgent selective arterial embolization to treat massive postpartum hemorrhage. Methods: Twenty-seven patients with ages of 21-53 years undergoing severe postpartum hemorrhage, were due to central placental previa, uterine atony, birth canal trauma, placenta accretio, cervical pregnancy etc. All of the patients had lost a volume of blood about 1000 ml to 5000 ml while the hemorrhage could not be controlled with vaginal packing and administration of uterotonic drugs. Urgent hemostatic embolization was performed for them. After angiography, super selective catheterization was performed for bilateral anterior division of internal iliac branch of uterine arteries and embolized with Gelfoam particles. Results: Catheterization success rate was 96.3%. Angiography showed ectopic uterine artery in one case. Immediate block of hemorrhage took place in 22 cases and gradual hemostasis appeared in 4 cases, the efficacy rate was 96.3%. The one with ectopic uterine artery was operated upon to ablate the uterus. 11 patients with (bleeding) shock and 8 patients with DIC were all saved. Conclusions: Urgent arterial embolization is an ideal method for treating life-threatening postpartum hemorrhage. The procedure saves the maternal uterus and is also effective for postpartum DIC

    Post-hemorrhagic hydrocephalus (PHH), also referred to as progressive ventricular dilatation, is caused by disturbances in cerebrospinal fluid (CSF) flow or absorption following hemorrhage in the brain. As one of the most serious complications of neonatal/adult intraventricular hemorrhage (IVH), subarachnoid hemorrhage (SAH), and traumatic brain injury (TBI), PHH is associated with increased morbidity and disability of these events. Common sequelae of PHH include neurocognitive impairment, motor dysfunction, and growth impairment. Non-surgical measures to reduce increased intracranial pressure (ICP) in PHH have shown little success and most patients will ultimately require surgical management, such as external ventricular drainage and shunting which mostly by inserting a CSF drainage shunt. Unfortunately, shunt complications are common and the optimum time for intervention is unclear. To date, there remains no comprehensive strategy for PHH management and it becomes imperative that to explore new therapeutic targets and methods for PHH. Over past decades, increasing evidence have indicated that hemorrhage-derived blood and subsequent metabolic products may play a key role in the development of IVH-, SAH- and TBI-associated PHH. Several intervention strategies have recently been evaluated and cross-referenced. In this review, we summarized and discussed the common aspects of hydrocephalus following IVH, SAH and TBI, relevant experimental animal models, clinical translation of in vivo experiments, and potential preventive and therapeutic targets for PHH.

  15. Spontaneous adrenal pheochromocytoma rupture complicated by intraperitoneal hemorrhage and shock

    Full Text Available Abstract MEN2A is a hereditary syndrome characterized by medullary thyroid carcinoma, hyperparathyroidism, and pheochromocytoma. Classically patients with a pheochromocytoma initially present with the triad of paroxysmal headaches, palpitations, and diaphoresis accompanied by marked hypertension. However, although reported as a rare presentation, spontaneous hemorrhage within a pheochromocytoma can present as an abdominal catastrophe. Unrecognized, this transformation can rapidly result in death. We report the only documented case of a thirty eight year old gentleman with MEN2A who presented to a community hospital with hemorrhagic shock and peritonitis secondary to an unrecognized hemorrhagic pheochromocytoma. The clinical course is notable for an inability to localize the source of hemorrhage during an initial damage control laparotomy that stabilized the patient sufficiently to allow emergent transfer to our facility, re-exploration for continued hemorrhage and abdominal compartment syndrome, and ultimately angiographic embolization of the left adrenal artery for control of the bleeding. Following recovery from his critical illness and appropriate medical management for pheochromocytoma, he returned for interval bilateral adrenal gland resection, from which his recovery was unremarkable. Our review of the literature highlights the high mortality associated with the undertaking of an operative intervention in the face of an unrecognized functional pheochromocytoma. This reinforces the need for maintaining a high index of suspicion for pheochromocytoma in similar cases. Our case also demonstrates the need for a mutimodal treatment approach that will often be required in these cases.

    Full Text Available Ventriculoperitoneal shunt is a routinely performed treatment in neurosurgical department. Intracerebral hemorrhage, as a complication after shunt catheterization, is really rare but with high mortality. In this study, we reported a case of a 74-year-old man who suffered from repeated intracerebral hemorrhage after ventriculoperitoneal shunt. The first hemorrhage happened 63 h after the 1st surgery, and most hematomas were located in the ipsilateral occipital lobe and intraventricles, along the ventricular catheter. Fresh blood clot casts blocked the external ventricular draining catheter, which was inserted into the right front horn during the 3rd surgery, indicating new intraventricular bleeding happened. A large hematoma in ipsilateral frontal lobe was detected on the 3rd day after the removal of external ventricular draining catheter. Different hemorrhagic locations and time points were encountered on the same case. We discussed the possible causes of repeated hemorrhage for this case, and the pre-operative preparation including risk evaluation in future clinical work.

    Full Text Available Objective: To report a case of recurrent vitreous hemorrhage from an optic nerve retinal arterial macroaneurysm (ONRAM successfully treated with intraoperative endolaser. Patient and Methods: A 92-year-old woman on oral aspirin and warfarin anticoagulation for atrial fibrillation developed three episodes of dense vitreous hemorrhage from an ONRAM. Due to failure of the vitreous hemorrhage to clear spontaneously, a total of three pars plana vitrectomy (PPV procedures were performed along with a 1.25-mg intravitreal bevacizumab injection after the third episode of hemorrhage. During the third PPV procedure, a 25-gauge 532-nm green diode laser endoprobe was used to deliver low-power (100 mW and long-duration (500 ms laser spots directly on the ONRAM to induce intraoperative shrinkage of the ONRAM. Results: After the endolaser treatment, the macroaneurysm showed involution due to fibrosis without any adverse effects on retinal circulation or visual field defect. No recurrence of vitreous hemorrhage was noted after 2 years of follow-up. Conclusion: Oral anticoagulant use may have been responsible for the atypical clinical course in our patient. Laser photocoagulation, including intraoperative endolaser photocoagulation, may be considered in selected cases of symptomatic ONRAMs.

    The aim of this study was to find the perinatal risk factors of intravenricular hemorrhage in twin neonates. A retrospective analysis of 203 twin pregnancies and deliveries between 2003 and 2009 was performed. Then data according birth state and neonatal complications in 406 twins were analyzed. Twin outcome was compared with the outcome of 105 singletons born at the same time and at the same gestational age as twins. Intraventricular hemorrhage was diagnosed in 116/406 (29%) of twins. IVH was found two times more often in the analyzed group than in singletons born at the same gestational age (29% vs. 18%, p = 0,03). In 96% I and II grade hemorrhage was diagnosed and in 4% III and IV grade hemorrhage in the Papille scale was found. 1) Intraventricular hemorrhage is found more often in twins than in singleton neonates born at the same gestational age. 2) IVH in twins correlate with preterm birth and low birth weight. IVH occur more often in twins with birth weight discordance and with too small maternal weight gain.

    Purpose. To investigate the sensitivity of mesenteric angiography, technical success of hemostasis, clinical success rate, and complications of transcatheter embolization for the treatment of acute nonvariceal gastrointestinal hemorrhage. Material and Methods. A retrospective review of 200 consecutive patients who underwent mesenteric arteriography for acute nonvariceal gastrointestinal hemorrhage between February 2004 and February 2011 was done. Results. Of 200 angiographic studies, 114 correctly revealed the bleeding site with mesenteric angiography. 47 (41%) patients had upper gastrointestinal hemorrhage and 67 (59%) patients had lower gastrointestinal hemorrhage. Out of these 114, in 112 patients (98%) technical success was achieved with immediate cessation of bleeding. 81 patients could be followed for one month. Clinical success was achieved in 72 out of these 81 patients (89%). Seven patients rebled. 2 patients developed bowel ischemia. Four patients underwent surgery for bowel ischemia or rebleeding. Conclusion. The use of therapeutic transcatheter embolization for treatment of acute gastrointestinal hemorrhage is highly successful and relatively safe with 98% technical success and 2.4% postembolization ischemia in our series. In 89% of cases it was definitive without any further intervention
