Filter by:This is a randomized, controlled, double-blind, placebo-controlled trial of intranasal Avastin (bevacizumab) injection versus saline control for control of HHT-related epistaxis when used in conjunction with bipolar electrocautery.
The purpose of the study is to identify novel genetic and protein markers for the process of cerebral vasospasm following aneurysmal subarachnoid hemorrhage.
100 women with abnormal uterine bleeding (peri and postmenopausal) were subjected to transvaginal ultrasound , saline sonohysterography , Diagnostic hysteroscopy and fractional curettage followed by histopathological examination and immunohistochemical analysis for estrogen and progesterone receptors.
The purpose of this study is to determine whether 40 mg octreotide long-acting release intramuscular every 28 days is effective in the treatment of patients with refractory anemia due to gastrointestinal angiodysplasias. We hypothesize that octreotide is effective in reducing the transfusion requirements (consisting of red blood cell transfusions and intravenous iron infusions) of patients with angiodysplasia-related anemia.
The purpose of the study is to investigate if briefly stopping blood flow to the patient's leg will lead to the patient's body being better able to tolerate possible decreased blood flow to regions of the brain which otherwise frequently happens after subarachnoid hemorrhage. Previous studies show that various organs such as the heart, brain or kidney can tolerate longer periods of decreased blood flow if prior to that insult shorter periods of decreased blood flow were experienced.
Patients with severe ischemic and hemorrhagic strokes, who require mechanical ventilation, have a particularly bad prognosis. If they require long-term ventilation, their orotracheal tube needs to be, like in any other intensive care patient, replaced by a shorter tracheal tube below the larynx. This so called tracheostomy might be associated with advantages such as less demand of narcotics and pain killers, less lesions in mouth and larynx, better mouth hygiene, safer airway, more patient comfort and earlier mobilisation. The best timepoint for tracheostomy in stroke, however, is not known. Preliminary data from a pilot study of early tracheostomy in patients with hemorrhagic or ischemic stroke suggest that such patients may also have improved survival and long-term functional outcomes, but a large, multicenter clinical trial is needed to confirm these findings.
Gastro-oesophageal varices (swollen veins in the gullet and stomach) are present in 50% of patients with liver cirrhosis and are its most serious complication as their rupture results in potentially life threatening bleeding. Bleeding from these veins occurs in up to one third of patients with varices. This is associated with 20% mortality at 6 weeks. In the event of bleeding from these veins the current UK guidelines recommend certain drugs followed by early endoscopic treatment with variceal band ligation (rubber bands placed over the veins to stop them bleeding). The use of a shunt inside the liver ("TIPSS" transjugular intrahepatic portosystemic shunt) is largely reserved for cases of uncontrolled bleeding from these swollen veins. A recent randomised multicenter study carried out by Garcia Pagan and colleagues reported improved survival with early TIPSS in patients with bleeding from these swollen veins in advanced liver disease. From these guideline international guidelines now recommend consideration of early TIPSS for all high-risk patients presenting with variceal bleeding. This practice clearly has significant cost implications. To validate the findings a further randomised control trial is needed. This is a multi-center parallel-group randomized controlled trial. Both hospitals taking part in the trial will have a TIPSS service. Patients who consent to enter the trial will be randomized to either: (1) Endoscopic treatment (standard care) or (2) early TIPSS. Potential participants will be all patients with a diagnosis of liver cirrhosis presenting with an acute variceal bleed to a participating hospital who do not fulfill an exclusion criteria. All causes of cirrhosis will be included. Participants will be reviewed during their regular hepatology clinic appointments at their respective hospitals on 3 occasions over a one-year period.
The aim of the study is to determine if the use of iv TXA or Aquamantys system improve the postoperative hemoglobin and hematocrit after primary TKA and what is the effect of the simultaneous use of iv TXA and Aquamantys on the postoperative hemoglobin and hematocrit. The assumption is that the combination of iv TXA and Aquamantys system will enable an improvement in the postoperative hemoglobin and hematocrit equal or larger than the improvement generated by the use of Aquamantys system alone.
The purpose of this study is to investigate the effect of stroke volume variation (SVV) guided fluid therapy on the blood loss and postoperative outcomes in radical cystectomy.
Traumatic brain injury (TBI) is the most common cause of acquired disability in youth and a source of significant morbidity and family burden. Novel behavior problems are among the most common and problematic consequences, yet many youth fail to receive needed psychological services due to lack of identification and access. Linking youth with TBI to effective treatments could improve functional outcomes, reduce family burden, and increase treatment satisfaction. The investigators overarching aim is to compare the effectiveness, feasibility, and acceptability of three formats of family problem solving therapy (F-PST) for improving functional outcomes of complicated mild to severe adolescent TBI: therapist-guided, face-to-face; therapist-guided online; and self-guided, online F-PST.
