Rituximab in refractory pemphigus vulgaris
2008
Pemphigus vulgaris (PV) is a severe chronic autoimmune blistering disease of skin and mucous membranes. The use of systemic corticosteroids in pemphigus has dramatically reduced its mortality rate, but the long-term use of steroids leads to severe side effects, many of which are serious. For this reason it is often necessary to add immunosuppressive agents to the regimen. However, there are occasional refractory cases in which therapy with conventionally accepted modalities is either not efficacious or not possible on account of side effects. Rituximab is a therapeutic monoclonal antibody targeting CD20, an integral membrane protein highly expressed on the surface of pre-B lymphocytes and a…
Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke
2020
Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism. A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thus allowing a diagnosis of ischemic stroke from paradoxical embolism.…
Topical Issues in Venous Thromboembolism
2010
Despite clear guidelines and the availability of effective treatments, venous thromboembolism (VTE) remains relatively common, particularly in the hospital setting. This paper reviews topical issues in VTE, in terms of treatments, data and guidelines. Existing anticoagulants have several limitations. Bleeding risk is a concern with all anticoagulants. Vitamin K antagonists are the mainstay of oral anticoagulant therapy, but they are limited by the need for frequent monitoring. Unfractionated heparin (UFH) is limited by an inconvenient route of administration (continuous intravenous infusion) and a higher risk of heparin-induced thrombocytopenia and bleeding compared with low molecular weigh…
Cost analysis of target-controlled infusion-based anesthesia compared with standard anesthesia regimens.
2000
UNLABELLED With the development of new computer-assisted target-controlled infusion (TCI) systems and the availability of short-acting anesthetics, total IV anesthesia (TIVA) has become increasingly popular. The aim of this study was to compare costs of TCI-based anesthesia with two standard anesthesia regimens. Sixty patients undergoing elective laparoscopic cholecystectomy were randomly divided into three groups. Group 1 (TIVA/TCI) received TIVA using a propofol-based TCI system and continuous administration of remifentanil; Group 2 (isoflurane) underwent inhaled anesthesia with isoflurane, fentanyl, and N2O; Group 3 (standard propofol) received fentanyl and N2O and a continuous infusion …

A Phase II Trial of Mitoxantrone plus Cyclophosphamide and 5-Fluorouracil in Modulation with Levo-Folinate for Advanced Breast Cancer Patients
1995
Advanced breast cancer remains a major clinical problem. Current chemotherapy regimens are able to induce a clinical response in many patients but do not appear to influence significantly patients' survival. The use of new drugs such as mitoxantrone with a predicted lower toxicity and biochemical modulation of 5-fluorouracil with levo-folinate are extensively studied research areas that could combine good therapeutic efficacy with the maintenance of an acceptable quality of life. 34 patients with advanced breast carcinoma were included in the study. Only 4 women had received prior chemotherapy for advanced disease. Treatment plan was: 5-fluorouracil 400 mg/m2 + l-leucovorin 100 mg/m2 days 1…
Evaluation of the Stratus® CS Acute Care™ D-dimer assay (DDMR) using the Stratus® CS STAT Fluorometric Analyzer: A prospective multisite study for ex…
2012
Abstract Background D-dimer testing is an integral part of the diagnostic algorithm in excluding patients with venous thromboembolism. In this study, we prospectively evaluated the Stratus DDMR D-dimer test in patients suspected of pulmonary embolism (PE) and deep vein thrombosis (DVT). Methods Patients suspected of venous thromboembolism were prospectively enrolled at four different clinical sites, with sodium citrate and lithium heparin plasma was tested using the DDMR D-dimer test on the Stratus CS analyzer. Results 1,012 patients were enrolled for analysis, with 85/603 (14.1%) patients with PE and 80/443 (18.1%) with DVT, and four of the patients (0.4%) with PE and DVT. For the samples …
Feasibility of a modified outpatient regimen of intravenous/intraperitoneal chemotherapy in optimally debulked stage III ovarian cancer patients: a G…
2011
Objectives: The objective of the study was to assess the feasibility, toxicity, and reasons for early discontinuation of a modified outpatient intraperitoneal/intravenous (IP/IV) chemotherapy regimen for the treatment of patients with optimally debulked stage III ovarian cancer. Methods: Between February 2006 and November 2008, 51 consecutive patients from Institutions of the Spanish Ovarian Cancer Group (GEICO) were treated with a modified outpatient IP chemotherapy regimen. Patients received IV paclitaxel 175 mg/m2 over 3 hours on day 1, followed by IP cisplatin 100 mg/m2 (or 75 mg/m2 according to the principal investigator9s criteria) on day 2. On day 8, patients received IP paclitaxel 6…
Endovascular Embolization of a Large High-Flow Splenic Arteriovenous Fistula and Aneurysm Using the Amplatzer Vascular Plug II.
2015
We describe the use of an Amplatzer Vascular Plug (AVP) II for embolizing a large high-flow splenic arteriovenous fistula and an aneurysm in a young patient. This patient presented to our center with persistent mild abdominal discomfort, 5 years after open splenectomy. Contrast-enhanced computed tomography angiography showed the presence of a fistula between the splenic arterial and splenic venous remnants and a resultant fusiform aneurysmal dilatation of the residual splenic vein. We decide to embolize the splenic artery with a 12-mm diameter AVP II with an oversizing by 70% of the vessel diameter. Celiac angiography performed 5 min postembolization revealed complete obliteration of the sp…
Involvement of Jugular Valve Insufficiency in Cerebral Venous Air Embolism
2007
Background. Cerebral venous air entrapment is a rare finding on cranial computed tomography (CT) scan. Peripheral air embolism is discussed as a potential cause. However, the mechanism of retrograde passage through internal jugular valves and veins is unclear. Case Report. The case of a patient is reported, who had air entrapment in the left cavernous sinus. Prior to CT scanning, a peripheral intravenous line had been placed. Ultrasound revealed excessive insufficiency of the left internal jugular valve. To further study the mechanism of embolism, an echo contrast agent was injected into the cubital vein. A Valsalva maneuver resulted in retrograde transition of microbubbles across the insuf…
