Evaluation of chemotherapy-induced cutaneous side effects in cancer patients.

Background: Cutaneous side effects are commonly seen in cancer chemotherapy. As new chemotherapy drugs are developed, the frequency and the diversity of these cutaneous side effects increase. For this reason, identification and management of these side effects are an important part of the treatment of cancer patients.

Endoscopic evaluation of acute intestinal graft-versus-host disease after allogeneic hematopoietic cell transplantation.

Background/aims: Acute graft-versus-host disease (GVHD) is a common complication of haematopoietic cell transplantation (HCT), with the gastrointestinal tract (GIT) as one of the main target organs. There is a lack of consensus regarding the site in GIT with the highest sensitivity for biopsy. The present study aimed to determine the endoscopic and histological findings in acute GVHD.

An Experimental Study of Radiation Effect on Normal Tissue: Analysis of HIF-1α, VEGF, eIF2, TIA-1, and TSP-1 Expression.

Objective: This study investigated whether or not the stress and hypoxia, which are the effects of radiation on normal vascular endothelium, leading to the release of HIF-1α, VEGF, eIF2, TIA-1, and TSP-1 were related and the possibility of them stimulating angiogenesis.


Materials And Methods: Twenty-four male Swiss Albino mice were separated into 4 groups. The first group was the control group (Group 1), and the second, third, and fourth groups were euthanized after 24 h (Group 2), 48 h (Group 3), and 7 days (Group 4), respectively.

Influence of febrile neutropenia period on plasma viscosity at malignancy.

Cancer, chemotherapy, and infections all together make changes in blood rheology and may affect the defense mechanisms by changing the thrombocyte function and endothelial cell. We have examined changes of blood rheology on plasma viscosity to put on probable following criteria for starting the treatment of febrile neutropenia immediately. A total of 27 postchemotherapy patients (16 males and 11 females) with febrile neutropenia diagnosed according to international guidelines have been included into the study.

Plasma viscosity: is a biomarker for the differential diagnosis of Alzheimer's disease and vascular dementia?

In this study, the importance of plasma viscosity (PV) as a biomarker in differential diagnosis of dementia subtypes especially Alzheimer's disease (AD) and vascular dementia (VaD) was investigated. Our study recruited 45 patients with AD, 35 patients with VaD, and control participants. Individuals with inflammatory disease, infection, heart, liver, renal failure, and with high erythrocyte sedimentation rate and C-reactive protein levels were excluded from the study.

Does reactive thrombocytosis observed in iron deficiency anemia affect plasma viscosity?

Objective: The accompanying thrombocytosis is referred to as the major factor associated with thromboembolism in iron deficiency anemia (IDA). Increased viscosity may increase the risk of thrombosis. We hypothesized that increased platelet count -with reactive thrombocytosis- might also affect plasma viscosity.

Cerebrospinal fluid viscosity: a novel diagnostic measure for acute meningitis.

Introduction: Early diagnosis of acute meningitis has paramount importance in clinical practice because of mortality and morbidity of the disease. Examination of cerebrospinal fluid (CSF) has critical value for the diagnosis of acute meningitis and discrimination of bacterial and aseptic meningitis. It has been previously reported that plasma viscosity can be used as an inflammatory marker.

Plasma viscosity and mean platelet volume in patients undergoing coronary angiography.

Background: Markers of platelet activation and haemorrheological indices have been demonstrated to play a role in the pathophysiology of atherosclerosis and cardiovascular events. In this study, we aimed at investigate the association between plasma viscosity and platelet indices in patients undergoing coronary angiography.

Materials And Methods: Three hundred and eighty four consecutive patients scheduled to undergo coronary angiography were included in the study.

Role of pleural viscosity in the differential diagnosis of exudative pleural effusion.

Objective And Background: Determining the aetiology of an effusion involves assessing if it is an exudate or a transudate. However, a reliable test for determining the aetiology of a pleural effusion is lacking. Pleural viscosity has a high sensitivity and specificity and a high positive and negative predictive value for discriminating exudative and transudative pleural effusions.

Alpha fetoprotein producing gastric hepatoid adenocarcinoma.

Gastric carcinoma generally as presents adenocarcinoma and rarely shows a hepatoid pattern, it may or not produce alpha-fetoprotein. The interpretation of the lesion may be difficult in a patient with a hepatic mass and raised alpha-fetoprotein level. A 51 year old man with hepatoid adenocarcinoma in stomach, producing alpha-fetoprotein is presented.

A simple laboratory measurement for discrimination of transudative and exudative pleural effusion: pleural viscosity.

Background: The initial step in establishing the cause of an effusion is to determine whether the fluid is a transudate or exudate. Plasma viscosity is influenced by the concentration of plasma proteins and lipoproteins with the major contribution resulting from fibrinogen. In this study we aimed to evaluate the role of pleural fluid viscosity in discrimination of transudate and exudates.

The role of thrombofilia related to Factor V Leiden and Factor II G20210A mutations in recurrent abortions.

Objective: To study, the impact of thrombophilia caused by Factor V, Factor ll G20210A mutations on recurrent abortions, the prevelance of Factor V Leiden and Factor II G20210A mutation in patients with habitual abortions.

Methods: Forty one patients with a diagnosis of habitual abortion were enrolled in the study. Control group consisted of 50 women without a history of poor obstetric outcome.

Effects of replacement fluids used for therapeutic plasma exchange on plasma viscosity and plasma oncotic pressure.

Introduction: Apheresis is a procedure in which one of the components of blood is removed. The aim of therapeutic plasma exchange (TPE) is to remove a large fraction of the patient's plasma from the body, and to exchange this with replacement solutions using automatic devices. With this procedure circulating pathogens and toxins are reduced.

Effects of replacement fluids on plasma viscosity used for therapeutic plasma exchange.

Plasmapheresis is a widely used alternative treatment for several diseases. Recently, synthetic plasma expanders have been used to reduce the cost of therapeutic plasma exchange (TPE). Hydroxyethyl starch (HES) is a polysaccharide colloid.

Therapeutic plasma exchange in a single center: Ibni Sina experience.

Background: The number of therapeutic procedures is increasing steadily year by year with growing collaboration of departments other than Hematology. In the aim to demonstrate our single center activity we analyzed our data since four years.

Methods: Between years 1998 and 2001, 658 therapeutic plasma exchange (TPE) procedures were performed on 158 patients.

Effects of replacement fluids on coagulation system used for therapeutic plasma exchange.

Therapeutic apheresis is a widely used treatment alternative for several diseases. In 29 patients with different diseases, we have monitored the PT, aPTT, thrombin time (TT), fibrinogen, D-dimer, factor VIII, IX, X, XI, XII, VWF, Protein C, S, Active Protein C Resistance (APCR) and Antithrombin-III during TPE. Patients were divided into four groups based on the replacement fluids used: 3% VARIHES or ISOHES + 4% albumin (1:1) (group 1), fresh frozen plasma (FFP) (group 2), 3% VARIHES or ISOHES (group 3) and 4% albumin (group 4).
