BACKGROUND: Many antagonists of histamine (H1) receptor, in addition to antihistamine action, suppress allergic inflammation by inhibiting the formation and secretion of proinflammatory cytokines. The new antiallergic drug benzhydrylpiperazinyl butylmethylxanthine succinate (theoritin), which has an antihistamine activity comparable to the known second generation H1-antihistamines, surpasses them in the ability to suppress the allergic inflammatory reaction, which allows this drug to have additional anti-inflammatory properties associated with the inhibition of the formation of proinflammatory cytokines. AIM: This study aimed to determine the effect of theoritin on the induced release of proinflammatory cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)- in cell culture in comparison with the action of the inverse agonist of H1 receptor cetirizine and a known inflammation inhibitor glucocorticosteroid dexamethasone. MATERIALS AND METHODS: U937 cells differentiated toward macrophage-like cells were used. Cytotoxicity of the substances used was assessed in the methyltetrazolium test at different incubation times (up to 24 h). Cells were stimulated with lipopolysaccharide (LPS). The tested compounds (theoritin and cetirizine) were evaluated at concentrations from 0.001 to 100 M and dexamethasone at 10 M was tested when added to cells 1 h before (prophylactic effect) or 1 h after (therapeutic effect) the addition of LPS. The presence of IL-6, IL-8, and TNF in the supernatants was determined by enzyme immunoassay. RESULTS: For cetirizine and theoritin, no cytotoxic action was found in the tested concentrations and time points. Dexamethasone inhibited the formation of IL-6 and TNF to the initial level and IL-8 to 50%60%. Theoritin led to a significant concentration-dependent decrease in the LPS-induced production of IL-6, IL-8, and TNF, and at a concentration of 100 M, the effect of theoritin was comparable with that of dexamethasone at a concentration of 10 M. The prophylactic test scheme for theoritin was more effective in suppressing LPS-induced production of proinflammatory cytokines than the curative one. The described effect of theoritin on LPS-induced production of proinflammatory cytokines exceeded that of the reference drug cetirizine. CONCLUSION: In addition to its antihistaminic action, theoritin, a new antiallergic agent, inhibits LPS-induced production of proinflammatory cytokines, which may be of clinical importance in suppressing allergic inflammation.

Abstract The modern clinician is a research consumer. Rehabilitation of oropharyngeal impairments, and prevention of the adverse outcomes of dysphagia, requires the clinician to select interventions for which evidence of a reasonable likelihood of a successful, important outcome exists. The purpose of this paper is to provide strategies for evaluation of published research regarding treatment of oropharyngeal dysphagia. This article utilizes tutorial and examples to inform and educate practitioners in methods of appraising published research. It provides and encourages the use of methods of efficiently evaluating the validity and clinical importance of published research. Additionally, it discusses the importance of the ethical obligation we, as practitioners, have to use evidence-based treatment selection methods and measurement of patient performance during therapy. The reader is provided with tactics for evaluating treatment studies to establish a study's validity and, thereby, objectively select interventions. The importance of avoiding subjective or unsubstantiated claims and using objective methods of generating empirical clinical evidence is emphasized. The ability to evaluate the quality of research provides clinicians with objective intervention selection as an important, essential component of evidence-based clinical practice.

Abstract. A broad range of literature reported higher rates of psychopathology and personality disorders among patients affected by skin conditions. Specifically, depression, anxiety, and suicidal ideations are more frequently reported by patients affected by skin diseases. This study aimed to examine psychopathology and personality in a group of patients affected by psoriasis by means of a self-report measure (Millon Clinical Multiaxial Inventory – MCMI-III) and a performance-based technique (Wartegg Drawing Completion Test [WDCT], CWS). Study results showed a higher rate of passive-aggressiveness and paranoia among psoriatic patients (MCMI-III). When assessing patients through the performance-based technique (WDCT, CWS), a higher rate of global rejection (GR) – linked by previous literature to suicidal ideation – and a lower affective quality of the drawings emerged. We discuss the clinical importance of detecting psychological issues in dermatology patients by means of a multimethod assessment that goes beyond patients’ self-evaluation of their symptoms and emotions.
