Szasz's absolutist approach in critiquing psychiatry, psychotherapy, and the concept of mental illness most famously expressed in The Myth of Mental Illness (Szasz, 1961). This article illustrates that Szasz mistook scientific proof for absolute truth. First, a comparison of scientific proof to its superior relation, mathematical proof, illustrates its theoretical short-comings. Szasz relies, sometimes subtly, sometimes quite overtly, but always selectively on "real science" to present psychiatry and the mental health fields as imposters in the field of medicine or health, while neglecting to see or discuss limitations of "science" in general and medicine in particular. Secondly, a summary of evidence supporting psychotherapy's effectiveness will be presented, the discussion of which was either consciously or unconsciously omitted in Szasz's (1978; 1988) The Myth of Psychotherapy. Third, summary of Pennington's (2002) integration of both biological and psychological basis of psychopathology through cognitive neuroscientific theoretical framework is presented as it reasonably addresses Szasz's confusion about and critique of mental illness and the mind-body problem.

Endothelins (ETs) are a family of three peptides (ET-1, ET-2, ET-3) that are implicated in the physiological control of vascular smooth muscle cell (VSMC) and myocardial contractility and growth. ET-1 is vasoactive peptide that acts via ET-A receptors coupling inducing vascular smooth muscle cell contraction. ET-1 is involved in the development and maintenance of hypertension. Aim of this study was to investigate whether ET-1 can induce vascular smooth muscle cell proliferation through arachidonic acid (AA) metabolites formed via cytochrome P¬450 (CYP-450). VSMC proliferation was measured by [3H]thymidine incorporation in cultured cells treated by ET-1 (10 to l00 nmol/L) in presence of different inhibitors of CYP-450 (17-ODYA 5 μmol/L), lipoxygenase (LO) (baicalein 20 μmol/L) and cyclooxygenase (COX) (indomethacin 5 μmol/L). ET-1 (10 to 100 nmol/L) induced VSMC proliferation and this effect was attenuated by CYP-450 inhibitor (17-ODYA) and lipoxygenase (LO) inhibitor (baicalein) but not by cyclooxygenase (COX) inhibitor (indomethacin). CYP-450 and LO metabolites of AA, 20-hydroxyeicosatetraenoic acid (HETE) and 12-HETE increased [3H]thymidine incorporation in VSMC. Inhibitors of MAP kinase (PD-98059 50 μmol/L) and cPLA2 (MAFP 50 μmol/L) attenuated ET-1 as well as 20-HETE induced VSMC proliferation. These results suggest AA metabolites via CYP-450 mediates ET-1 induce VSMC proliferation.

Potential risk of sudden death during sports participation makes screening of competitive athletes of vital importance. Congenital cardiac anomalies and non-atherosclerotic, acquired myocardial conditions are primary causes underlying exercise-induced cardiac death in young patients. Since cardiovascular conditions are the leading causes of non-traumatic, exercise-induced cardiac events, cardiovascular screening preceding sports participation in mandatory. The objectives of this study were to determine prevalence of cardiac conditions through cardiovascular screening of young athletes and to establish preventive strategy. The study was conducted at the Sports Medicine Center of Sarajevo Canton and at the Pediatric Clinic of University of Sarajevo Clinics Centre in the period 2007-2009. The study was supported by Canton Sarajevo Ministry of Health and Ministry of sports, science and culture. The study targeted a group of 214 athletes, 8-18 years of age with average age being 15.26. The group was subdivided into five groups according to the age. After taking the anamnesis (family, personal and cardiological) patients were subjected to the measuring of body mass and height, blood pressure and heart rate and oxygen saturation, recording of 12-lead ECG, specialist examination (pediatrician, sports medicine specialist and cardiologist) and complete heart echocardiography. No examined athletes expressed subjective discomfort. Congenital cardiac anomalies were not diagnosed in any athlete. Also, cardiovascular abnormalities requiring additional evaluation, positive cardiac anamnesis, abnormal auscultatory findings, hypertension or abnormal ECG findings were not recognized in any patient. Moderate correlation was found among the left ventricle mass and heart rate (p<0.05). In order to minimalize or even possibly prevent the risk of sudden cardiac death it is necessary to establish an adequate strategy of cardiovascular screening of young athletes.
