Problematic computer use is a growing social issue which is being debated worldwide. Internet Addiction Disorder (IAD) ruins lives by causing neurological complications, psychological disturbances, and social problems. Surveys in the United States and Europe have indicated alarming prevalence rates between 1.5 and 8.2% [1]. There are several reviews addressing the definition, classification, assessment, epidemiology, and co-morbidity of IAD [2-5], and some reviews [6-8] addressing the treatment of IAD. The aim of this paper is to give a preferably brief overview of research on IAD and theoretical considerations from a practical perspective based on years of daily work with clients suffering from Internet addiction. Furthermore, with this paper we intend to bring in practical experience in the debate about the eventual inclusion of IAD in the next version of the Diagnostic and Statistical Manual of Mental Disorders (DSM).

These results confirm the importance of patients' expectations in the prediction of postsurgical outcomes and underline the necessity to optimize these expectations in order to improve postoperative quality of life.

Future studies should use objective and subjective assessment. Focusing on efficacy, clinicians should favor benzodiazepine receptor agonists and classical benzodiazepines over antidepressants (including low-dose doxepin) for primary insomnia treatment, but the additional consideration of different side effect profiles can lead to alternative treatment decisions.

Prolonged dehydration and starvation in the dog result in the sacrifice by the organism of more potassium than that derived from the breakdown of tissue (1). There is no comparable sacrifice of sodium. As a result, the diminution of intracellular fluid is exaggerated while that of extracellular fluid is minimized. (6) where bci and bNa = balance of chloride and of sodium, respectively. El = initial extracellular fluid = liters corresponding to one-fourth of the body weight in kilograms. Cl1 and Cl2 = initial and final concentration of chloride in extracellular water. Na, and Nag = initial and final concentration of sodium in extracellular water. The concentrations of chloride, sodium, and potassium in extracellular water (ECW) were calculated from the serum concentrations (s) This was estimated in two independent ways. AII (first method) = AW -AEc0,AIII (second method) = 2.7 Pwhere Wt. = initial body weight in kilograms, P = protein burned, in kilograms, bK' = bK -(KEcW2 X E2) + (KEOW X El)-380 P = balance of "excess" potassium, bK = total balance of potassium, AB = B2-Bi, B = NaBCw + 10 m.eq. per liter.(12) (13) (14) 93

In light of these strong placebo responses, future studies should investigate how to exploit placebo mechanisms in clinical practice.
