Introducing a Quality Assurance methodology appears particularly useful in Radiation Oncology due to the complexity of the procedures involved and the heterogeneity of the standards adopted, if any, in the great majority of the Centers. There are two possible ways of evaluating quality in the Health Environment: a formal, Institutional certification, or a voluntary one obtained through a mechanism of peer review. The European Society for Therapeutic Radiology and Oncology (ESTRO) started in 1994 with the publication of a methodological Report intended to be adopted by the individual national Societies, and this paper is an invitation to do it.

The wall paintings in the Oratorio of San Giovanni Battista in Urbino: a study finalized to a correct conservation project.

The walls of the Oratorio of San Giovanni Battista in Urbino are decorated with outstanding mural paintings dating back to the 15th century. Due to degradation processes that have occurred in the past years, such paintings require a conservative restoration project. In order to evaluate reasons of the decay, some scientific studies have been performed. They consist of macroscopic observations and chemical (EDS), morphological (SEM) and mineralogical (XRD) analyses of samples both from the original preparatory layers under the painted layers and from the restored plasters at the surbase of the wall. In addition, environmental studies have been performed to verify microclimatic conditions of the church in which the mural paintings are located. Finally, a conservative restoration project was proposed.

[Septic shock in a case of purulent pericarditis. Usefulness of hemodynamic study with Swan-Ganz catheterization].

In a case of cardiac tamponade the hemodynamic study with Swan-Ganz catheter was useful to confirm the diagnosis and to assess the correct therapy, otherwise the case was complicated with septic shock by purulent pericarditis and could mislead the diagnosis.

Mucolipidosis I: ocular signs in three sisters.

In inborn errors of metabolism ocular signs can often represent an early symptom and permit a presumed diagnosis which must be confirmed by biochemical studies. Moreover the ocular signs indicate the evolution of the illness together with other general symptoms.

[Loco-regional thrombolysis in deep venous thrombosis].

Anticoagulation, by means of heparin and warfarin is, till now, the most common treatment in deep venous thrombosis. Although thrombolytic agents have been available for over 10 years, their use remains quite low, ranging from 15 to 20% of deep venous thromboses. This is due to the relatively high incidence of contraindications as well as to the fact that the potential advantages versus heparin are diminished by the increased bleeding risk and by the potential risk of pulmonary embolism (migration of partially lysed thrombi). Following the example of the "triple armed therapy" proposed by Rosenthal for the treatment of pulmonary embolism, we will evaluate if loco-regional thrombolysis, with the catheter wedged against the thrombus, associated with a temporary vena cava interruption by means of an intraluminal filter, can achieve a better lysis of the thrombus without pulmonary embolism. In our Unit 18 patients affected by proximal deep venous thrombosis were submitted to thrombolytic therapy, 6 to systemic treatment, 3 to local treatment and the last 9 to loco-regional thrombolysis, using recombinant tissue-type Plasminogen Activator. We obtained 10 complete lyses, 1 with systemic and 9 with loco-regional treatment. There were no major complications. Thus, we think that venous loco-regional thrombolysis with rt-PA at lower doses, associated with temporary caval interruption, can probably achieve a better lysis than systemic treatment without risk of pulmonary embolism and with a very low haemorrhagic risk, as in arterial loco-regional thrombolysis. Furthermore, loco-regional thrombolysis, by means of a faster thrombus dissolution, could better prevent post-phlebitic syndrome.

[Validity of computer simulation in closed circuit anesthesia].

Developing a computer program to simulate the uptake, distribution, and elimination of inhalational anesthetics allow the anesthesiologist to address specific problems, but intense skills are required to translate the involved process first into a set of mathematical equations and then into a satisfactory computer program. The first step is facilitated by solutions offered in the literature. The second step by personal computer program now currently available as Gus, this program simulates anesthetic uptake and distribution using a numerical model with 12 compartments. Transport of anesthetic agents among the compartment occurs via convection of gas and blood during discrete iteration of the simulation. As initial clinical validation of the linear 12 compartment basic model the current study examined the predictive performance in 20 patients by comparing quantitatively the predicted and the measured alveolar concentration-time profiles after achievement of end tidal concentration of isoflurane (C-alv%) injected into a heated chamber (75 degrees) and then transported in closed circuit system during mechanical ventilation. With regard to the use of isoflurane 20 patients were adequately anesthetized with only 88 ml of liquid isoflurane and that is the same in simulation achieved by computer.
