Evaluation of the systematic set-up errors using electronic portal image device in the radiotherapy procedures

Objective： The aim of this work was to quantify the extent of set-up errors to conduct a quality assurance （QA） aspect of treatment delivery, verification of the treatment field＇s position on different days using electronic portal. Methods： This study was carried out on 12 patients, treated for pelvis tumor; and total of 240 images obtained by electronic portal image device （EPID） were analyzed. The EPIs acquire using EPID attached to the Siemens linear accelerator. The anatomy match- ing software （Theraview） was used and displacement in two dimensions were noted for each treatment field to study patient setup errors. Results： The percentages of mean deviations less than 5 mm in X direction were 65% ＆ 92%, from 5-10 mm were 31% ＆ 19% and more than 10 mm were 11% ＆ 9% forNP and lateral direction respectively. The percentages of mean deviations less than 5 mm in Y direction were 65% ＆ 63%, from 5-10 mm were 33% ＆ 28% and more than 10 mm were 22% ＆ 29%. The mean deviations in 2D-vector errors were 〈 5 mm in 47% and 46%, 5-10 mm in 36% and 37% and 〉 10 mm in 37% and 37% of images in the NP and lateral direction respectively. Conclusion： The results revealed that the ranges of set up errors are immobilization method to improve reproducibility. The observed variations were not within the limits..     

Telematics enabled virtual simulation system for radiation treatment planning

In this paper, GALENOS, a Telematics Enabled Virtual Simulation System for Radiation Treatment Planning (RTP) is described. The design architecture of GALENOS is in accordance with the dual aim of virtual simulation of RTP, i.e. to allow (a) delineation of target volume and critical organs, and (b) placement of irradiation fields. An important feature of GALENOS is the possibility for on-line tele-collaboration between health care professionals under a secure framework. The advantages of GALENOS include elimination of patient transfers between departments and health care institutions as well as availability of patient data at sites different than those of his/her physical presence.     

Posttraumatic stress reactions among children following the Athens earthquake of September 1999

Abstract. The objective of the present study was to assess symptoms of posttraumatic stress disorder (PTSD), depression and anxiety among children 6 months after they had been exposed to an earthquake (EQ) affecting the northwestern suburbs of Athens in September 1999. A total of 115 children attending two elementary schools located at the epicentre of the EQ were assessed. A group of 48 children not affected by the EQ attending a school not affected by the EQ were used as controls. The children and their parents completed a number of questionnaires. Overall, there was a high rate (78%) of severe to mild PTSD symptoms in the EQ exposed group. Additionally, a substantial proportion of these children scored above criteria (32%) for depression compared to the control group (12.5%). Severe or moderate symptoms of PTSD were associated with high scores of depression (p = 0.002). The relationship between PTSD symptoms and anxiety was limited to the avoidance factor of the anxiety questionnaire (p = 0.029). Those who were most likely to be affected were children alone at the time of the EQ, and children who sustained injuries. In summary, countries where EQs are frequent should be prepared to offer psychological support to a substantial proportion of children presenting with PTSD and depressive symptoms and should educate and prepare children to cope with these events.     

A murine monoclonal antibody that blocks fibrinogen binding to normal platelets also inhibits fibrinogen interactions with chymotrypsin- treated platelets

We recently described a monoclonal antibody, 10E5 , that completely blocks adenosine diphosphate (ADP) induced fibrinogen binding to platelets and aggregation induced by ADP, epinephrine, and thrombin. Multiple lines of evidence indicate that 10E5 binds to platelet membrane glycoproteins IIb and/or IIIa. Because it has been reported that platelets treated with chymotrypsin aggregate when fibrinogen is added, we tested the effect of 10E5 antibody on chymotrypsin-induced fibrinogen binding and platelet aggregation. Aspirin-treated human platelets were washed in modified Tyrode's buffer (pH 7.5), incubated for 5 minutes at 22 degrees C with 300 micrograms/mL chymotrypsin, and washed again. The amount of 10E5 antibody bound to these platelets (37,232 +/- 2,928 molecules/platelet; mean +/- SEM, N=9) was similar to that bound to unstimulated control platelets (36,910 +/- 2,669) and did not differ significantly from the amount of antibody bound to ADP- treated platelets (P less than .01, N = 5). The amount of 10E5 bound to chymotrypsin-treated platelets correlated directly with the amount of fibrinogen bound to separate aliquots of the same platelet samples (r = .876, P less than .001). The 10E5 antibody caused virtually complete inhibition of both the binding of fibrinogen to chymotrypsin-treated platelets and the aggregation induced by exogenous fibrinogen. Immunoprecipitation studies of 125I-labeled chymotrypsin-treated platelets revealed that the 10E5 antibody bound proteins with molecular weights characteristic of glycoproteins IIb and IIIa. These data suggest that the fibrinogen receptor on chymotrypsin-treated platelets is identical to that on ADP-treated platelets and that this receptor is either near to, or on, the glycoprotein IIb/IIIa complex.     

Results of percutaneous transluminal angioplasty

Percutaneous transluminal angioplasty (Dotter technique) was used in 2,942 cases of iliofemoral atheromatous disease. Results varied with the characteristics of the obstructing lesion (length and location) and the clinical stage of ischemia (claudication, rest pain, gangrene). Based on the foregoing, angioplasty is done either as the preferred primary treatment or for the relief of clinically advanced disease in patients unsuitable for high risk surgery. Success is favored by the use of aggregation inhibitors and single-use Teflon or balloon catheters; complications are few.
