Determination of Minimal Erythema Dose and Anomalous Reactions to UVA Radiation by Skin Phototype

2014

Background: Phototesting is a technique that assesses the skin’s sensitivity to UV radiation by determining the smallest dose of radiation capable of inducing erythema (minimal erythema dose [MED]) and anomalous responses to UV-A radiation. No phototesting protocol guidelines have been published to date. Methodology: This was a multicenter prospective cohort study in which 232 healthy volunteers were recruited at 9 hospitals. Phototests were carried out with solar simulators or fluorescent broadband UV-B lamps. Each individual received a total of 5 or 6 incremental doses of erythemal radiation and 4 doses of UV-A radiation. The results were read at 24 hours. Results: At hospitals where sola…

Cardiovascular comorbidity in multiple sclerosis patients treated with mitoxantrone therapy: a cohort study

2017

Abstract Background Mitoxantrone (MX) has been used as second line therapy for aggressive multiple sclerosis (MS). Potential cardiotoxic effects of MX limit its use; a cumulative dose of up to 100 mg/m2, has been long considered relatively safe. We calculated the frequency of cardiac side effects in MS patients treated with MX. Methods We performed a cohort study including all MS patients treated with MX at the Neurological Department of the University Hospital of Palermo, Italy. Two hundred-sixty-four MS patients diagnosed according to validated criteria were included and followed-up until the end of September 2010. Patients were treated with MX as a second line therapy if they had no prev…

Effects of diazinon exposure on cholinesterase activity in different tissues of European eel (Anguilla anguilla).

1996

Cholinesterase (ChE) activity was measured in brain, plasma, and whole eye of Anguilla anguilla experimentally exposed to a sublethal concentration of 0.042 mg/liter (0.50 of the 96-hr LC50) of the organophosphorous pesticide diazinon. Whole eye was the tissue which revealed higher values of ChE activity (8.17 micromol/min/g) in nonexposed animals. Brain, plasma, and whole eye ChE activity of A. anguilla was inhibited at 6, 24, 48, 72, and 96 hr of diazinon exposure. Pesticide induced significant inhibitory effects on the ChE activity of this species ranging from >70% inhibition in brain tissue to >90% in plasma samples. Brain and plasma presented technical difficulties in their collection.…

Risk assessment of Bundeswehr (German Federal Armed Forces) permethrin-impregnated battle dress uniforms (BDU).

2007

In an age when vector-borne diseases are emerging worldwide, personal protective measures are essential for shielding soldiers and other exposed persons from arthropod attack. The development of permethrin-impregnated clothing has been one recent advance in protecting persons at-risk. However, to date risk assessment has not been performed related to wearing permethrin-impregnated clothing over longer time periods. Therefore, this paper describes relevant toxicological aspects of permethrin and estimates the extent of dermal permethrin uptake by soldiers wearing impregnated uniforms by determining urine metabolites of permethrin. The exposure monitoring conducted in wearers of untreated uni…

Pharmacokinetics of anidulafungin during albumin dialysis

2014

In the ICU setting, current guidelines recommend echi-nocandins as the first-line treatment for invasive candi-diasis [1]. Albumin dialysis (AD) has been used in theICU as supportive therapy for hepatic failure, but thistechnique can significantly enhance drug elimination [2].We prescribed anidulafungin for suspected invasivecandidiasis in a patient with severe liver failure treatedwith AD and measured the plasma concentrations of thedrug using high-performance liquid chromatography.This study (GEF-ANI-2010-02) was approved by thelocal ethics committee (INCLIVA, Institute of Research,Valencia, Spain) and written informed consent wasobtained from the patient’s next of kin. An adult patientwa…

Low-Dose Aclacinomycin and Intermediate-Dose Cytosine Arabinoside in Relapsed and Refractory Acute Myelogenous Leukemia

1990

Nineteen patients with relapsed or refractory acute myelogenous leukemia were treated with escalating doses of aclacinomycin (ACLA 20–30 mg/m2 daily for 5 days) and intermediate-dose cytosine arabinoside (Ara-C 1 g/m2 twice daily for 4 days). Most patients had received previous therapy with high- or intermediate-dose Ara-C plus mitoxantrone (HAM, IAM) and TAD (6-thioguanine, standard-dose cytosine arabinoside, and daunorubicin). Four patients had had repeated relapses and another three were treated for primary treatment failure following induction with HAM or I AM.

Assessment of Mobilization Cost for Multiple Myeloma Using 2 Different Mobilization Strategies: High-Dose Cyclophosphamide Versus Plerixafor. on Beha…

2016

Abstract Background. Peripheral blood stem cell (PBSC) collection prior to high dose chemotherapy for autologous transplantation (ASCT) is a standard of care, and an attractive alternative to the use of bone marrow cells, for transplantation in Multiple Myeloma (MM). The optimal methodology for mobilizing PBSC has yet to be defined, both G-CSF and GM-CSF can be used; although, the stimulatory effect may be more pronounced when given after high dose cyclophosphamide (usually administered at a dose of 1.5 to 6g/m2 IV for one to two days) and use of Plerixafor, a CXCR4 antagonist (Mozobil®). The latter 2 options are preferred, overall, in France. Indeed, it was shown that the most recent combi…

Verification of a commercial implementation of the Macro-Monte-Carlo electron dose calculation algorithm using the virtual accelerator approach.

2009

Abstract In this work, the accuracy of the implementation of the Macro Monte Carlo electron dose calculation algorithm into the radiation therapy treatment planning system Eclipse is evaluated. This implementation – called eMC – uses a particle source based on the Rotterdam Initial Phase-Space model. A three-dimensional comparison of eMC calculated dose to dose distributions resulting from full treatment head simulations with the Monte Carlo code package EGSnrc is performed using the ‘virtual accelerator’ approach. Calculated dose distributions are compared for a homogeneous tissue equivalent phantom and a water phantom with air and bone inhomogeneities. The performance of the eMC algorithm…

Study of serum ctx in 50 oral surgical patients treated with oral bisphosphonates

2011

Objectives: To determine whether there is a relationship between the total BP dose administered and the variations in serum CTX concentration. Study design: The study included 50 patients requiring dental implant surgery and treated with oral BPs, seen in an Oral Surgery and Implantology Unit between January 2007 and June 2009. The patients were divided into two groups: those in which the medication was not suspended before obtaining the laboratory test sample, and those patients referred from other dental clinics in which BPs was suspended before reporting to our Unit. The total drug dosage administered and the total dose per kilogram body weight were evaluated for comparison with serum CT…
