Objective . This study was set to assess the effect of renal dysfunction on outcome of stroke patients treated with intravenous thrombolysis (IVT). Methods . This multicenter research involved 403 patients from January 2009 to March 2015. Patients were divided into two groups: (1) control group with GFR ≥ 45 mL/min/1.73 m2 and (2) low GFR group with GFR < 45 mL/min/1.73 m2 . Outcome measurements were poor outcome (mRS 3-6) and mortality at 3 months and symptomatic intracerebral hemorrhage (SICH) within the first 24-36 hours...

BACKGROUND Toxic epidermal necrolysis (TEN) is characterized by widespread erythematous and bullous lesions on the skin. Nowadays, considerable progress has been made in the understanding of its pathogenesis. Immunologically it is similar to graft-versus-host disease. Therefore, we may propose that TEN is a disorder of cell-mediated immunity. CASE REPORT Our patient was a 74-year-old white female who had pneumonia and was positive for hepatitis C virus (HCV), and who had been on levofloxacin therapy. After the first levofloxacin dose, erythematous dusky red macules occurred on her extremities and trunk, and on the following day, confluent purpuric lesions tended to run together over 85% of her body...

OBJECTIVES: Also to the inflammatory demyelinating lesions and degenerative process, altered cerebrovascular reactivity or neurovascular coupling (NVC) might be considered as playing another role in the pathogenesis of multiple sclerosis. The objective of this study is to assess the NVC of patients with relapsing-remitting multiple sclerosis (RRMS) during the acute exacerbation period. PATIENTS AND METHODS: Four hundred fifty-eight patients with RRMS and 160 healthy subjects were screened for this study during the last 14 years...

The current study presents the results of the activity of radionuclides in spa waters, and evaluates their radiological influences on the population consuming these waters in the Central and Eastern Black Sea regions of Turkey. Since these waters are used for therapy and consumption purposes unconsciously, their radiological impact on the people was computed by taking into consideration the annual intake through ingestion of (226)Ra, (232)Th, (40)K, (137)Cs and (222)Rn. The mean activities were estimated to be 11...

BACKGROUND: The relatively late approval of use of recombinant tissue plasminogen activator (rt-PA) for acute ischemic stroke in Turkey has resulted in obvious underuse of this treatment. Here we present the analyses of the nationwide registry, which was created to prompt wider use of intravenous thrombolysis, as well as to monitor safe implementation of the treatment in our country. METHODS: Patients were registered prospectively in our database between 2006 and 2013...

BACKGROUND: Surgical site infections (SSIs) are a threat to patient safety; however, there were no available data on SSI rates stratified by surgical procedure (SP) in Turkey. METHODS: Between January 2005 and December 2011, a cohort prospective surveillance study on SSIs was conducted by the International Nosocomial Infection Control Consortium (INICC) in 20 hospitals in 16 Turkish cities. Data from hospitalized patients were registered using the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) methods and definitions for SSIs...

UNLABELLED: Abstract Objectives: To evaluate subclinical left ventricular and right ventricular systolic impairment in dipper and non-dipper hypertensives by using isovolumic acceleration. METHODS: About 45 normotensive healthy volunteers (20 men, mean age 43 ± 9 years), 45 dipper (27 men, mean age 45 ± 9 years) and 45 non-dipper (25 men, 47 ± 7 years) hypertensives were enrolled. Isovolumic acceleration was measured by dividing the peak myocardial isovolumic contraction velocity by isovolumic acceleration time...

Background. The relationship between the arterial recanalization after intravenous recombinant tissue plasminogen activator (rtPA) and outcomes is still uncertain. The aim of our study was to evaluate whether there is an association between the pulsatility indexes (PI) of the middle cerebral artery (MCA) measured by transcranial Doppler (TCD) after iv rtPA treatment and short- and long-term outcomes in ischemic stroke patients. Methods. Forty-eight patients with acute ischemia in the MCA territory who achieved complete recanalization after the administration of intravenous thrombolytic treatment were included in the study...

The aim of this study was to evaluate the prevalence of aspirin resistance (AR) in patients undergoing hemodialysis (HD) and to assess the effect of HD on the results of the Multiplate test. A total of 54 patients undergoing HD were included in this study. Blood samples were taken just before and after the HD session. To determine AR, we used Multiplate test. Platelet aggregation values of the study population were 363.01 ± 225.69 aggregation unit (AU) × minutes before and 375.33 ± 254.05 AU × minutes after the HD (P = ...

AIM: The aim of our study was to evaluate atrial electromechanical delay (AEMD) and left atrial mechanical functions (LAMF) in the patients with secundum-type atrial septal defect (ASD). METHOD: We included 72 patients with secundum type ASD in the study group and 35 gender and age-matched healthy volunteers for the control group. Maximal, minimal, and presystolic LA volumes were measured by modified Simpson method and indexed to the body surface area (BSA).

BACKGROUND: Patients with pseudo-dementia are at particular risk of being labeled as Alzheimer dementia. We thus need better diagnostic methods. In this study, we evaluated the cerebral reactivity of the posterior cerebral arteries (PCAs) during visual stimulation by transcranial Doppler ultrasonography. METHODS: The study group consisted of 13 and 11 patients suffering from pseudo-dementia and Alzheimer disease (AD), respectively, and 10 healthy controls. Visual reactivity was defined as the differences of cerebral blood flow velocity (CBFv) against the visual stimulus...
