[The use of intra-arterial lipiodol in assessing hepatocarcinomas treated by percutaneous alcoholization. The initial experience].

Eight patients with inoperable hepatocellular carcinoma were treated by means of percutaneous alcoholization of the malignancy (11 nodular lesions less than 5 cm O). Upon treatment completion they were all given intraarterial injection of lipiodol, which was followed, a week later, by a CT scan. At angiography, during the parenchymal phase, 7 of 11 nodules appeared as avascular areas, whereas in the remaining 4 cases an intense parenchymal effect was seen within the previously treated areas. Lipiodol CT scans revealed intense uptake of oily material in the 4 hypervascular lesions as well as in 1 of those with avascular appearance. In 4 lesions, pathology of bioptic specimens obtained from the areas with contrast pooling was consistent with the persistence of viable neoplastic tissue. In these patients alcoholization had therefore to be continued. Lipiodol accumulation within previously treated nodules has proved to be related to the presence of residual neoplasm. Moreover, in 2 cases, focal retention of lipiodol was very helpful for biopsy under CT guidance. According to our experience, we believe lipiodol administration followed by CT to be very useful in evaluating and staging HCCs. We nevertheless believe that the procedure should be performed only after alcoholization has been completed: this would inform us of treatment effectiveness and subsequently enable us to decide whether treatment can be discontinued.

[The prosthetic saddle in physiognomic reconstruction of the dental-alveolar arches].

The investigation of 2087 patients with partially extended, subtotal and total edentations who presented to the Clinic of Dental Gnathoprosthetics of Iaşi made possible the assessment of the role and importance of prosthetic saddle in the physiognomic restoration in such patients. By applying the modern clinical and technical methods of designing and making the gnathoprosthetic apparatus, the physiognomy of dento-alveolar arches according to actual exigencies and observing the dento-facial harmony can be achieved.

[Physiognomic reconstruction of the dental arches in emergency treatment].

The gnathoprosthetic treatment in emergency is now a compulsory step in solving the esthetic problems raised by the affections of stomatognathic system (coronary lesions, edentation) localised in visible areas of dental arches. Nowadays, the state of stress induced by these affections can be relieved by an immediate and highly physiognomic treatment, a method at hand being the Scutan mask. Excellent technic results can be obtained by using conformators obtained by thermoplasticizing and vacuumating, in current use in our clinic.

[Physiognomic reconstruction of the frontal arch with a microprosthesis].

The connective restoration of dental arches still raises physignomic problems. The less visible in the context of individual's facial architecture the more esthetic the prosthetic artifice is. Based on the statistic data of the Iaşi Clinic of Dental Prosthetics the results of the gnathoprosthetic treatment performed in the years 1987 and 1988 in 1,751 patients were evaluated. The efficiency was estimated by the quantitative relation between the various types of prostheses used in restoring the integrity of frontal arch.

[The diagnosis of mental discomfort during dental prosthetic treatment].

The authors present the forms the psychic discomfort may take during the prosthetic treatment and the importance of their diagnosis. This paper is the result of the investigations carried out in the Office of psychognathoprosthetics of the Clinic of Dental Prosthetics of Iaşi and synthesizes the results obtained by the prepsychiatric examination of 180 patients.

AIDS prevention among Hispanics: needs, risk behaviors, and cultural values.

Data from different sources show that Hispanics are over-represented in reported cases of acquired immunodeficiency syndrome (AIDS) (twice their proportion of the population) and that their rate of infection by human immunodeficiency virus (HIV) is three times higher than among non-Hispanic whites. The behavior risk factors most frequently associated with infection in AIDS cases are IV drug use in the Northeast and high-risk sexual behavior in the West. HIV infection prevention strategies for Hispanics need to address high risk behaviors, taking into consideration associated culture-specific characteristics. Strategies need to address as well conditions such as racism and ethnic prejudices that keep many Hispanic homosexuals and bisexuals away from white or non-Hispanic gay organizations and publications, the lack of culturally appropriate drug treatment centers, the level of mis-information among Hispanics, and the possible high incidence among men of sexual intercourse with prostitutes. Prevention campaigns need to include such Hispanic cultural values as simpatia, familialism, personalismo, and power distance, if prevention campaigns are going to be perceived as relevant by Hispanics. Appropriate wording and communication channels need to be identified in order to transmit messages that will be perceived as credible and that will reach the largest possible audience.

[The prevention of mental discomfort in gnathoprosthetic treatment].

The investigation of a series of patients following a treatment at the Clinic of Gnathoprosthetics of Iaşi made possible an evaluation of their general emotional state in relation with their dental problems. According to the obtained results, the emotional discomfort induced by the numerous specific and unspecific gnathoprosthetic factors was avoided by means proper to each category of patients.

[The health education of the young employees of an industrial unit].

This paper underlines the role of health education as a prophylactic means and presents an original methodology of the Clinic of Dental Prosthetics of Iaşi. This methodology was applied to a group of young employees of a heavy industry unit and consisted in comments upon some specific booklets and folders and physician-patient talks, as part of the examination. The follow-up record facilitated the assessment of subjects receptivity and at the same time the initiation of an early treatment of the bucco-dental lesions.

Some specific features of exercise stress in athletes.

Stress factors which can elicit several psychoemotional, neuromotor and cardiovascular reactions in athletes before or during training and competition are discussed. The authors' data concern firstly the significance of ACTH depletion. Exploration of the neuromotor system, the flicker test, evaluation of the urinary excretion of amine metabolites and several types of questionnaires (related to stress, anxiety and coronary risk factors) in a group of 35 athletes have outlined their psychophysiological reactions and behaviour. The necessity to prevent and manage distress phenomena found in 20 subjects is considered.
