Triple radioisotope technique in etiologic evaluation of space-occupying lesions of the liver.

The findings from 43 patients with histologically proven focal liver disease examined by triple isotope tracer study are presented. The method consisted in a three step technique, the first step being an isotope scan after injection of 99mTc-sulfur colloid and 131I rose bengal. As a second step dynamic hepatic scintiangiography was carried out with 99mTc human serum albumin in order to assess the vascularity of a lesion detected on the initial scan. Thirdly, the patient was administered 67Ga to evaluate further the pathologic process. According to our results this triple radioisotope technique provides the clinician with valuable information on the possible etiology of focal liver disease.

[The being ill of the schizophrenic approached from existential analysis].

Schizophrenia is one of the most pervading and obscure mental deseases. No scientific explanation--either somatogenic or psychogenetic--has attained, so far, a comprehensive grasp of schizophrenic ways of experiencing the world. Not that the valuable research made in many branches of Psychiatry is to be belittled because of being parcial or single-oriented: it is necessary a completely different approach--from a phenomenological standpoint-- provided by Daseinanalyse, to encompass the richess and complexity of schizophrenic experience. In that view, "being-ill" is, for the schizophrenic, a basic impairment of the capacity of "being-open-to" the human environment, and a correlative lack of "feeling-of-the-self", an incapability to be what one really is. The consequence is a loss of freedom, a basic difficulty to face the world and to reach its meaning together with the meaning of one's own life. Three cases are discussed, in which the patients are overwhelmed by other's actions and thoughts, and cannot tell apart what pertains really to their own inner world. They are even absorbed by inanimate elements, or by ordinary objects of everyday life. Everything is a threat to their nonexisting beings. Once such a grasp of the complexities of schizophrenic "way-of-being-in-the-world" is attained, it is possible to work towards the development of the patient's own self, to help to expand and strenghthen the individual inner "roots" in order to gain a higher level of individual entity that enables the patient to face the world without the risks and perils of being engulfed in its maelstroms.

Ethanol elimination in males and females: relationship to menstrual cycle and body composition.

Ethanol pharmacokinetics were determined following oral ethanol, 0.5 gm per kg, in nine normal women and 10 normal men, and related to total body water measured by 3H-water dilution and body fat determined anthropometrically. Ethanol pharmacokinetics were similar in the females throughout the menstrual cycle. No variation was seen in mean peak blood ethanol concentration or elimination rate in the midfollicular (Days 8 to 10) and midluteal (Days 22 to 24) phases. Mean peak blood ethanol values were significantly higher in females (88 +/- 3 mg per 100 ml) than in males (75 +/- 4 mg per 100 ml) (p less than 0.05), and the mean area under the ethanol concentration-time curve was significantly greater in females (241 +/- 12 mg X hr per 100 ml) than in males (177 +/- 11 mg X hr per 100 ml) (p less than 0.001). There was no significant sex difference in mean ethanol elimination rates. The mean apparent volume of distribution of ethanol in female (0.59 +/- 0.02 liter per kg) was less than in males (0.73 +/- 0.02 liter per kg) (p less than 0.001). Both apparent volume of distribution of ethanol and area under curve were significantly correlated with total body water suggesting that the sex differences in ethanol pharmacokinetics were due to sex differences in body water content. The sex differences in ethanol pharmacokinetics may partly explain reports of male-female differences in the natural history of certain ethanol-related disorders.

Gender differences in mood and cardiovascular responses to socially stressful stimuli.

Filmed vignettes of socially stressful situations elicit changes in emotional states and physiological activation. Several studies have reported changes in mood and physiological activity in African Americans who encountered laboratory analogs of stressful situations. However, none have examined gender differences. African-American college students (52 women and 40 men) viewed two versions of one of two social stressors. In one instance, the perpetrator of the stressful circumstances was Caucasian, while in the other, a Black perpetrator was viewed. Order of viewing was counterbalanced. The scenes depicted either an unjust arrest for shoplifting or an encounter with a rude and threatening highway patrolman. Analyses of variance determined that increases in blood pressure occurred as the stressful scenes were viewed, though no increases occurred in response to the neutral material. Women reported more tension, distress and fear during the stressors while the men evidenced more pronounced elevations in blood pressure. The findings encourage further study of the impact of social stress on physiological and emotional processes.
