SUMMARY – Saliva is a complex body fluid that has various functions in the oral cavity. Central nervous system has the most important role in regulating salivation. Saliva as a sample is suitable for simplicity of sampling and because it contains analytes in the free active form. Stress is a condition in which the internal (psychophysical) balance of the body is disturbed. It activates the hypothalamic-pituitary axis, so salivary cortisol is a free cortisol indicator that correlates well with its serum value and reflects the free fraction that is biologically active. At the same time, stress conditions stimulate the sympathetic neuronal system causing change in the secretion of salivary α-amylase from salivary glands. The hypothesis of this study was that students with daily intensive physical activity are exposed to chronic stress compared to other students who have minimal physical activity. The study included 54 healthy volunteers, students of the University of Zagreb, divided into two groups. One volunteer group consisted of physically active volunteers (n=27) from the Faculty of Kinesiology (FK), and the other group consisted of physically inactive volunteers (n=27) from other faculties (OF). The subjects were first administered a psychological test that consisted of two questionnaires, Quality of Life Questionnaire and Questionnaire of Stressful Styles, and then underwent sampling of saliva. By comparing biochemical and psychological indicators in relation to stress, it was concluded that the two groups of students were equalized and that there was no objective support for either group to be considered exposed to chronic stress. Despite the substantial differences in physical activity, there was no difference between the two student populations.

IntroductionDue to its mood-stabilizing properties, clozapine is known for reducing symptom severity in manic episodes of treatment-resistant bipolar disorder as well as in treatment-resistant schizophrenia. However, its use may be hindered by potential adverse effects, including hematologic ones, such as non-dose-dependent eosinophilia. The mechanism of the underlying process probably involves a type-I hypersensitivity reaction, which can manifest as either transient asymptomatic eosinophilia or as eosinophilia with multiorgan dysfunction.ObjectivesWe present the case of a patient diagnosed with manic episode of schizoaffective disorder who developed eosinophilia, with severe systemic manifestations, in response to clozapine therapy. A review of literature will be conducted in order to provide further insight into the phenomenon.MethodsCase report and literature review.ResultsThe incidence of eosinophilia reported in literature ranges between 0.2% and 62%, with its appearance about three weeks after clozapine initiation. Although clozapine is an antipsychotic that normally requires frequent monitoring due to the potential side effect of agranulocytosis, we would like to place emphasis on the possible risk of eosinophilia, in connection with potential fatal complications. As described in this report, eosinophilia could long remain unrecognized due to subsequent multiorgan involvement, including lymphadenopathy, leukocytosis, lymphopenia, anemia, liver enzyme elevations, as well as pleural effusion, all of which were described in our patient.ConclusionsClozapine-associated eosinophilia may be used as an early marker of possible clozapine-induced systemic complications and it may warrant prompt discontinuation of the causing drug, as suggested by the literature.

The book is divided in four parts. The first part is an Introduction to Cognitive Screening Instruments and Assessment of the Utility of Cognitive Screening Instruments. The second part includes chapters that talk about patients' performance-related test, the third one discusses informant-related scales, and the fourth one is the conclusion. The first part discusses rationale and desiderata for effective cognitive screening instruments. In addition there is mention of a potential risk such as age, education and culture on test performance and interpretations. Nowadays when in dementia diagnosis we use sophisticated neuroimaging techniques and biochemical tests, the role of cognitive testing is being investigated. It is interesting that some authors consider that cognitive tests can be useful in predicting the conversion and decline of patients with moderate cognitive damage at risk of progressing de
