Accumulation of blood in the EPIDURAL SPACE between the SKULL and the DURA MATER, often as a result of bleeding from the MENINGEAL ARTERIES associated with a temporal or parietal bone fracture. Epidural hematoma tends to expand rapidly, compressing the dura and underlying brain. Clinical features may include HEADACHE; VOMITING; HEMIPARESIS; and impaired mental function.
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury.

Systemic infection with Alaria americana (Trematoda). (1/4329)

Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. Hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.  (+info)

Novel endotheliotropic herpesviruses fatal for Asian and African elephants. (2/4329)

A highly fatal hemorrhagic disease has been identified in 10 young Asian and African elephants at North American zoos. In the affected animals there was ultrastructural evidence for herpesvirus-like particles in endothelial cells of the heart, liver, and tongue. Consensus primer polymerase chain reaction combined with sequencing yielded molecular evidence that confirmed the presence of two novel but related herpesviruses associated with the disease, one in Asian elephants and another in African elephants. Otherwise healthy African elephants with external herpetic lesions yielded herpesvirus sequences identical to that found in Asian elephants with endothelial disease. This finding suggests that the Asian elephant deaths were caused by cross-species infection with a herpesvirus that is naturally latent in, but normally not lethal to, African elephants. A reciprocal relationship may exist for the African elephant disease.  (+info)

Warfarin therapy: evolving strategies in anticoagulation. (3/4329)

Warfarin is the oral anticoagulant most frequently used to control and prevent thromboembolic disorders. Prescribing the dose that both avoids hemorrhagic complications and achieves sufficient suppression of thrombosis requires a thorough understanding of the drug's unique pharmacology. Warfarin has a complex dose-response relationship that makes safe and effective use a challenge. For most indications, the dose is adjusted to maintain the patient's International Normalized Ratio (INR) at 2 to 3. Because of the delay in factor II (prothrombin) suppression, heparin is administered concurrently for four to five days to prevent thrombus propagation. Loading doses of warfarin are not warranted and may result in bleeding complications. Interactions with other drugs must be considered, and therapy in elderly patients requires careful management. Current dosing recommendations are reviewed, and practical guidelines for the optimal use of warfarin are provided.  (+info)

Risk factors for severe hemorrhagic cystitis following BMT. (4/4329)

Hemorrhagic cystitis (HC) is a common toxicity of preparative regimens for bone marrow transplantation (BMT). Severe HC often requires prolonged and expensive hospitalization, and occasionally can result in death. To investigate the risk factors for severe HC, we conducted a retrospective study among 1908 patients who received BMTs at the University of Minnesota during 1974 to 1993. A previous report from our institution reported on 977 of these patients. We identified all patients with genitourinary complication within 100 days post-BMT from the BMT database. Medical charts for these patients were reviewed to determine whether the patient had HC and also the grade of HC. A total of 208 HC cases were identified during the study period. Of them, 92 patients had severe HC, an incidence of 5% (95% CI = 4-6%). We found that grade II-IV graft-versus-host disease (RR = 2.56; 95% CI = 1.43-4.56), use of busulfan (RR = 2.69; 95% CI = 1.35-5.35), and age at transplant (RR = 2.20; 95% CI = 1.27-3.81, for age of 10-30 compared to age of 0-9) were related to an increased risk of HC. In contrast, transplant year was inversely associated with the risk of HC (trend test, P < 0.01). We did not find any significant difference in HC with the use of prophylactic Mesna.  (+info)

The effects of levonorgestrel implants on vascular endothelial growth factor expression in the endometrium. (5/4329)

Vascular endothelial growth factor (VEGF) expression and the microvascular density of the endometrium were studied in Norplant users and normal controls, using immunohistochemistry on formalin-fixed paraffin-embedded endometrial sections. The VEGF staining index was quantified using computerized image analysis. The VEGF staining index between stages of the menstrual cycle and between normal and Norplant endometria were compared. Norplant VEGF staining index was analysed for correlation with microvascular density, duration of Norplant use, the number of bleeding/spotting days in the reference period up to 90 days prior to biopsy, and the length of time since the last bleeding/spotting episode. The results showed that immunoreactive VEGF was detected predominantly in endometrial glands but weakly expressed in the stroma throughout the menstrual cycle, and also in Norplant users. Large variation in the VEGF staining index between individuals was observed and no significant difference in the VEGF staining index was detected between stages of the menstrual cycle for the glands and stroma. The glandular and stromal VEGF staining indices were significantly higher in Norplant than in normal endometrium (P<1x10(-4)). No correlation was found between the Norplant VEGF staining index and endometrial microvascular density, duration of Norplant use, the number of bleeding/spotting days in the reference period, and the length of time since the last bleeding/spotting episode. The VEGF staining index was higher in glands than stroma for both normal and Norplant endometrium. The results suggest a differential control of endometrial glandular versus stromal VEGF expression, and possible positive effects of levonorgestrel on VEGF expression.  (+info)

Late massive haemoptyses from bronchopulmonary collaterals in infarcted segments following pulmonary embolism. (6/4329)

Massive, recurrent haemoptyses requiring blood transfusions occurred in a patient who had been diagnosed as having pulmonary thromboembolism 3 months earlier. To the authors' knowledge this is the first case report of this kind, in which massive haemoptyses were proved to be caused by large bronchopulmonary collaterals that had developed in the infarcted lung segments affected by embolism. Selective embolization of the collaterals proved to be therapeutic and life saving.  (+info)

Bileaflet mechanical prostheses for aortic valve replacement in patients younger than 65 years and 65 years of age or older: major thromboembolic and hemorrhagic complications. (7/4329)

OBJECTIVE: To determine major thromboembolic and hemorrhagic complications and predictive risk factors associated with aortic valve replacement (AVR), using bileaflet mechanical prostheses (CarboMedics and St. Jude Medical). DESIGN: A case series. SETTING: Cardiac surgical services at the teaching institutions of the University of British Columbia. PATIENTS AND METHODS: Patients 2 age groups who had undergone AVR between 1989 and 1994 were studied. Group 1 comprised 384 patients younger than 65 years. Group 2 comprised 215 patients 65 years of age and older. RESULTS: The linearized rates of major thromboembolism (TE) occurring after AVR were 1.54%/patient-year for group 1 and 3.32%/patient-year for group 2; the rates for major TE occurring more than 30 days after AVR were 1.13%/patient-year for group 1 and 1.55%/patient-year for group 2. The crude rates for major TE occurring within 30 days of AVR were 1.04% for group 1 and 3.72% for group 2. The death rate from major TE in group 1 was 0.31%/patient-year and in group 2 was 0.88%/patient-year. Of the major TE events occurring within 30 days, 100% of patients in both age groups were inadequately anticoagulated at the time of the event, and for events occurring more than 30 days after AVR, 45% in group 1 and 57% in group 2 were inadequately anticoagulated (INR less than 2.0). The overall linearized rates of major hemorrhage were 1.54%/patient-year for group 1 and 2.21%/patient-year for group 2. There were no cases of prosthesis thrombosis in either group. The mean (and standard error) overall freedom from major TE for group 1 patients at 5 years was 95.6% (1.4%) and with exclusion of early events was 96.7% (1.3%); for group 2 patients the rates were 90.0% (3.2%) and 93.7% (3.0%), respectively. The mean (and SE) overall freedom from major and fatal TE and hemorrhage for group 1 patients was 90.1% (2.3%) and with exclusion of early events was 91.2% (2.3%); for group 2 patients the rates were 87.9% (3.1%) and 92.5% (2.9%), respectively. The 5-year rate for freedom from valve-related death for group 1 patients was 96.3% (2.1%) and for group 2 patients was 97.2% (1.2%). CONCLUSION: The thromboembolic and hemorrhagic complications after AVR with bileaflet mechanical prostheses occur more frequently and result in more deaths in patients 65 years of age and older than in patients years younger than 65 years.  (+info)

Adenovirus infection after pediatric bone marrow transplantation. (8/4329)

Retrospective analysis of 206 patients undergoing 215 consecutive bone marrow transplants (BMT) at St Jude Children's Research Hospital between November 1990 and December 1994 identified 6% (seven male, six female) with adenovirus infection. The affected patients had a median age of 7.9 years (range 3-24 years) at time of transplantation. Although transplants were performed for hematologic malignancies, solid tumors or nonmalignant conditions, only patients with hematologic malignancies had adenoviral infections. Adenovirus was first detected at a median of 54 days (range -4 to +333) after BMT. Adenovirus developed in eight of 69 (11.6%) patients receiving grafts from matched unrelated or mismatched related donors, in four of 52 (7.7%) receiving grafts from HLA-matched siblings, and in one of 93 (1.1%) receiving autografts. The most common manifestation of adenovirus infection was hemorrhagic cystitis, followed by gastroenteritis, pneumonitis and liver failure. The incidence of adenovirus infection in pediatric BMT patients at our institution is similar to that reported in adult patients. Using univariate analysis, use of total body irradiation and type of bone marrow graft were significant risk factors for adenovirus infection. Only use of total body irradiation remained as a factor on multiple logistic regression analysis.  (+info)

We retrospectively investigated outcomes of emergency TAE for the management of life-threatening haemorrhage in patients with uncorrected bleeding diathesis. This multicenter, retrospective, study, was designed to investigate the safety and efficacy of percutaneous TAE for the management of life-threatening haemorrhage in patients with uncorrected bleeding disorder at the time of embolization. All consecutive patients with uncorrected coagulation who underwent TAE for the treatment of haemorrhage, between January 1st and December 31th 2019 in three European centers were included. Inclusion criteria were thrombocytopenia (platelet count | 50,000/mL) and/or International Normalized Ratio (INR) ≥2.0, and/or activated partial thromboplastin time (aPTT) | 45 s, and/or a pre-existing underlying blood-clotting disorder such as factor VIII, Von Willebrand disease, hepatic cirrhosis with abnormal liver function tests. Primary outcome measures were technical success, rebleeding rate and clinical success.
Background: Life-threatening diffuse alveolar hemorrhage has been successfully treated with recombinant-activated human factor VII (rFVIIa) in 3 different conditions: 2 small-vessel vasculitis-associated diseases and bone marrow transplantation (1).

Pulmonary hemorrhage (or pulmonary haemorrhage) is an acute bleeding from the lung, from the upper respiratory tract and the trachea, and the alveoli. When evident clinically, the condition is usually massive. The onset of pulmonary hemorrhage is characterized by cough productive of blood (hemoptysis) and worsening of oxygenation leading to cyanosis. Treatment should be immediate and should include tracheal suction, oxygen, positive pressure ventilation, and correction of underlying abnormalities (e.g. disorders of coagulation). A blood transfusion may be necessary. The outcome of treatment is dependent on causality. Pulmonary Hemorrhage is present in 7 to 10% of neonatal autopsies, but up to 80% of autopsies of very preterm infants. The incidence is 1 in 1,000 live births. Pulmonary hemorrhage has a high mortality rate of 30% to 40%. Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predispose to perinatal asphyxia or ...
Background: The occurrence of diffuse alveolar hemorrhage (DAH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is rare but severe. There are few reports that have examined the correlation between pre-HSCT chemotherapeutic exposure and DAH. Objectives: We examine the role of pre-HSCT chemotherapeutic exposure, conditioning regimens, pre-HSCT comorbidities and transplant-related complications in the development of DAH after allo-HSCT and evaluate the effect of the high-dose corticosteroid strategy on DAH. Methods: A retrospective nested case-control study was designed. Cases with DAH and controls matched for year of allo-HSCT and length of follow-up were identified from a cohort of 597 patients who underwent allo-HSCT between 2006 and 2011 for acute leukemia. Results: Twenty-two patients suffered from DAH; the mean age at the time of presentation was 30.4 years (+/- 12.9) and the mean time to presentation was 7.8 months (+/- 8.1) post-HSCT. The pre-HSCT cyclophosphamide ...

Diffuse, bilateral, hazy airspace opacities predominately in the mid to low lung zones. Overall, these findings are nonspecific, but with known history of pulmonary hemorrhage after bronchoscopy or clinical findings of hemoptysis and anemia, these findings are consistent with diffuse pulmonary hemorrhage.
Hemorrhage into atherosclerotic plaques has been recently reported in histopathologic studies, associated with larger plaque necrotic cores, as well as greater lipid content and macrophage infiltration. Whether intraplaque hemorrhage is simply associated with larger or more complex plaques or indeed stimulates plaque progression has not been clarified. In this issue, Takaya and colleagues use serial cardiovascular magnetic resonance imaging studies of the carotid arteries over 18 months in patients with carotid atherosclerosis to demonstrate that the presence of intraplaque hemorrhage on the initial examination was associated with greater progression of plaque atherosclerosis. Those with hemorrhage at baseline had greater progression of lipid-rich necrotic core volume as well as wall volume, independent of the volume of hemorrhage components, and were also more likely to have recurrent plaque hemorrhage. These important data suggest that intraplaque hemorrhage contributes significantly to the ...

Results Patient characteristics were similar between those with and without MO or IMH (table 1). The infarct zone demonstrated recovery of strain with time (p≤0.01, figure 1). Epicardial strain recovered over time in the presence of MO with IMH and without IMH, (p=0.03, p,0.01 respectively), but mid-myocardial or endocardial strain did not (mid-myocardium: p=0.05, p=0.12; endocardium: p=0.27, p=0.05). By day 90, infarcts with MO had more attenuated strain than those without (p,0.01); those with IMH were attenuated further (p,0.01). Remote myocardial strain was similar across groups at all time points, regardless of infarct characteristics (p,0.2 for all, figure 1). Infarct transmural extent did not correlate with strain values (p,0.05 at each time point). Multivariable regression showed MO and IMH to be independently associated with attenuated strain (p=0.004, p=0.011). ...

a ) Arterial hemorrhage may be recognized by rapid, spurting jets of red blood, occurring synchronous with the heart beat.. (b ) Venous bleeding (from a vein) occurs as a steady even stream of dark blood, not affected by the heart beat.. (c ) Capillary hemorrhage is in the form of a steady stream oozing from the raw surface of a tissue. The color is intermediary, as both arterial and venous capillaries contribute to it.. Natures Efforts to Control Hemorrhage. When an artery is severed, the inner and middle coats immediately retract and curl up within the lumen, partially closing up the cut end.. Blood has the property of clotting, if it comes in contact with anything but the natural endothelial lining of the vessels.. The curling in of the inner and middle coats retards the escaping stream and facilitates coagulation within the cut end of the vessel now formed by the outer coat alone. When the hemorrhage is severe, these processes are reinforced by an increased tendency to coagulate, and by a ...

The role of ultrasound (US) guidance either as real time imaging or prebiopsy site marking was not directly addressed as a potential risk modifier in the present study. This is probably because the majority (80%) of the biopsies were described as ultrasound-guided which likely limited the comparison. Whether or not the patients with bleeding were equally distributed in the US-guided group versus those without image guidance would be interesting but is not reported. However, given the size of the small arteriolar vessels that may be the source of severe hemorrhage (Figure 2) and the limitations of ultrasound resolution, it seems very unlikely that ultrasound guidance will have an effect on the risk of severe hemorrhage. This assessment is supported by several prior observational studies and a controlled trial of US-guided versus nonguided biopsy.21, 22, 23 In the latter study, a substantial difference in the complication rate (including bleeding) between US-guided and non-US-guided biopsy was ...

Over a modern trip to the horse track, my friend, who was experiencing his to start with time with the races, was perusing the Daily Racing Form when he inquired about what the L following to a horses name meant. I explained this meant that the animal was on medication Lasix. He asked about what Lasix was. I explained it was a drug administered to many horses to help stop them from blood loss.. He commenced asking even more inquiries on the medication: why some horses didnt utilize it, why other people were only using it for your first time, and so on. I realized, I was going towards the track for a lot of many years and did not seriously have every one of the answers considering that I by no means paid considerably awareness to the use.. I figured because Id been going for the track for many years and under no circumstances certainly understood all the information, that there had been in all probability quite a few of you who fell into that category as well.
