The evidence regarding the co-morbidity of chronic hepatitis C, psychiatric illness and intravenous drug abuse is reviewed from the literature. Also the occurrence and the treatment of psychiatric side effects during treatment with interferon in patients with a history of drug abuse are reviewed. There is insufficient evidence for a specific hepatitis C induced depression or fatigue, but a direct link between hepatitis C and cerebral dysfunction is not excluded. Immune system activation rather than drug use may explain cerebral symptoms. In HCV positive substance users anxiety and depression are more prevalent than in HCV negative substance users. During treatment with regular or pegylated (PEG) interferon depression is a frequent side effect (ca 30%) and occurs independently from pre-existing psychiatric disorders or drug abuse. A history of drug abuse per se does not increase the risk of depression as a side effect of interferon treatment. It is extremely important to monitor symptoms of depression in the early weeks of treatment and to start antidepressant treatment as early as possible. Antidepressants should be continued throughout the interferon treatment period. There are insufficient data to assess these situations in which preventive antidepressant treatment should be started before interferon treatment. Clinical judgement can, however, lead to preventive antidepressant treatment, even at subclinical levels of depression. A cut off score of > 10 on the Beck Depression Inventory before interferon treatment is associated with a higher risk of depression during treatment. Both selective serotonin reuptake inhibitors and other classes of antidepressants can be used.

Twenty-six in-patients with Diagnostic and Statistical Manual version IV (DSM-IV) criteria for opioid dependence were selected at random to receive either a combination of an 11-day low-dose buprenorphine and a 14-day carbamazepine regimen (n = 14) or a combination of an 11-day methadone and a 14-day carbamazepine regimen (n = 12) in a double-blind, randomized 14-day in-patient detoxification treatment. Patients with buprenorphine and carbamazepine showed a significantly better psychological state after the first and second weeks of treatment. Above all, the buprenorphine-treated patients demonstrated a less marked tiredness, sensitiveness and depressive state as well as a more prominent elevated mood during the detoxification process. Seven non-completers (after 7 days: four of 12 = 33.3%; after 14 days: seven of 12 = 58.3%) were treated with methadone and carbamazepine and five non-completers (after 7 days: two of 14 = 14.3%; after 14 days: five of 14 = 35.7%) received buprenorphine and carbamazepine. The difference in the overall dropout rate after day 14 was not significant. The present study supports the hypothesis that the combination of buprenorphine and carbamazepine leads to a better clinical outcome than does a combination of methadone and carbamazepine in the detoxification of opioid addicts with additional multiple drug abuse. The buprenorphine and carbamazepine-regimen provides a more effective short-term relief of affective disturbances than does methadone and carbamazepine. No severe side effects occurred during the treatment period in both groups.

It has been reported that hepatitis C virus (HCV) infection is associated with cognitive dysfunction, fatigue and depression, which do not correlate with the severity of liver disease and cannot be accounted for by hepatic encephalopathy or drug abuse. There is also emerging evidence that HCV infection can have negative neurocognitive effects in HIV-infected cohorts. Magnetic resonance spectroscopy has suggested the likely existence of a biological basis for these effects. HCV replicative forms have recently been detected in autopsy brain tissue and the infected cells have been identified as CD68-positive (macrophages/microglia). These findings raise the possibility that HCV infection of the brain could be directly related to the reported neuropsychological and cognitive changes. HCV is not strictly hepatotropic, as it can also replicate in leukocytes, including monocytes/macrophages. The latter cells could provide access of HCV into the central nervous system ('Trojan horse' mechanism) in a process similar to that postulated for HIV-1. In support of this hypothetical mechanism come reports showing a close relationship between HCV sequences present in the brain and cerebrospinal fluid and sequences found in lymph nodes and peripheral blood mononuclear cells. However, despite some similarities there is a fundamental difference between HIV-1 and HCV infection as the latter does not progress into AIDS-type dementia.

The objective was to investigate perceptions of snowfield resort visitors about injury risk regarding alcohol, fatigue and recreational drug use. Visitors to a resort village in a large Australian snowfield region completed a brief survey about fatigue, alcohol and recreational drug use and injury risk perception. Participants stated their ability to ski or snowboard and drive safely following a lack of sleep, alcohol and recreational drug use. Intoxicated snowfield resort visitors were compared with non-intoxicated visitors. Safety beliefs across snow sport and transport were compared. Participants reported that they generally slept less than usual and 30% reported both drinking alcohol and using drugs more than usual while visiting the snowfields. Participants perceived driving as a greater injury risk than skiing/snowboarding (p < 0.001). Fatigue was perceived as a relatively weak injury risk factor, particularly whilst skiing and snowboarding. Awareness needs to be raised among snowfield resort visitors about the contribution of alcohol, fatigue and recreational drug use to snow sport and transport-related injury risk.

Progesterone is a steroid hormone that is important for reproductive function. Progesterone is used in a number of clinical applications and has been investigated as a possible novel approach for treatment of stimulant drug abuse. Extensive clinical studies have been conducted to examine the subjective and physiological effects of exogenous progesterone administration and to evaluate its side effects. This review summarizes the safety and side effects of acute and chronic administration of 3 progesterone formulations (synthetic, natural, and micronized natural), several routes of administration (oral, intramuscular, intravenous, intravaginal, intranasal, transdermal, and rectal), and dosing regimens. Synthetic progestins marketed as Provera, PremPro, and Cycrin are widely used but may produce a number of significant side effects, such as fatigue, fluid retention, lipid level alterations, dysphoria, hypercoagulant states, and increased androgenicity. Natural progesterones are reported to have milder adverse effects, depending on the route of administration. Micronized natural progesterone is available for oral administration, has better bioavailability and fewer side effects than natural progesterone, and is convenient to administer. Therefore, micronized natural progesterone appears to be a safe and effective alternative to synthetic and natural progesterone formulations for variety of clinical and research applications.

60-90% of patients with intravenous drug abuse are chronically infected with the hepatitis C virus (HCV). Antiviral treatment with pegylated interferon-alfa (IFN-alpha) plus ribavirin is often complicated by psychiatric adverse events, significantly affecting patients adherence. Depression, anxiety, fatigue and irritability as typical IFN-alpha associated side effects occur in 30-80% during antiviral treatment of hepatitis C. Patients with drug addiction were shown to have an increased risk to discontinue HCV-treatment early in the first three treatment months, where most neuropsychiatric side effects appear. Especially vegetative side effects in the first few weeks ("flu-like syndrome") can be misunderstood as withdrawal symptoms, followed by a relapse in drug or alcohol abuse. As a consequence methadone substitution treatment was found to be the best therapeutic setting. In addition side effect management should be intensified during first three months of HCV-treatment. Most data for the management of specific IFN-alpha associated side effects are available for depressive syndromes. Antidepressants (especially serotonin-reuptake-inhibitors) such as citalopram were shown to significantly reduce IFN-alpha associated depressive symptoms. A pre-emptive treatment with antidepressants should be considered at least for patients with additional psychiatric risk factors before interferon-based therapy is started. Because data from prospective controlled trials are lacking, management of other side effects such as sleep disturbances, irritability, psychotic syndromes, mania, suicidal thoughts and delirious syndromes should follow general psychiatric treatment recommendations. Overall, the psychiatric adverse event profile of interferon-based therapy for HCV-infected patients with drug addiction is considerable and requires active management and knowledge about psychiatric medical therapy.

Depression is one of the most prevalent mental disorders, according to Hungarian and international data. In Western- Europe, lifetime prevalence of major depression is 13%, while one-year prevalence is 4%. The prevalence of severe depressive symptoms is similar in Hungary: approximately 5 to 8% of all patients seen by primary care physicians suffer from some kind of depressive disorders. Depression is more prevalent in women and in the elderly. According to the World Health Organization, depression is the third most common disabling disorder. Patients with depression experience impaired quality of life, anxiety, sleep disturbances, alcohol and drug abuse, and different somatic disorders. Furthermore, depression is the most important risk factor for suicide. Primary care physicians have a crucial role in the screening and diagnosing of depressive disorders. Depressive disorders can exist not only in patients complaining about depressed mood, but also in patients with "medically unexplained symptoms" (headache, fatigue, abdominal pain, gastrointestinal symptoms, weight change). Primary care physicians should have appropriate knowledge about the different therapeutic options (including various psychotherapies, antidepressant medications and other treatment options) to be able to treat their patients properly. We review the literature about the significance and epidemiology of depression and summarize the diagnostic and therapeutic options of depressive disorders in primary care practice.

There are numerous problems with the hypothesis that brain dopamine (DA) systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements). Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum) also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.

Child abuse is known to correlate with drug abuse and interferes with recovery from substance-related disorders. To determine the prevalence and severity of child abuse among drug addicts, we conducted a nationwide cross-sectional survey of residents and outpatients at drug addiction rehabilitation centers (DARC) in Japan. A total of 445 participants gave informed consent and completed a self-reporting questionnaire. Sixty-eight percent of participants had experienced some kind of child abuse by the time they reached junior high school. The kinds of abuse experienced were physical (53.7%), psychological (60.4%), sexual (5.4%) abuse and neglect (24.5%). Comparison of female and male participants revealed that more female than male participants had experienced psychological (76.9% vs. 58.2%) and sexual (17.5% vs. 4.0%) abuse. Comparison of participants who had experienced some kind of child abuse ("Abused" group 68.3%) and those who had not experienced abuse ("Non-abused" group 24.3%) revealed that the "Abused" group was younger than the "Non-abused" group (35.7 SD9.0 vs. 39.7 SD10.8). Participants in the "Abused" group were found to have more severe psychological difficulties than those in the "Non-abused" group for the following: anxiety (73.0% vs. 61.1%), delusional atmosphere (48.0% vs. 28.7%), lack of energy (53.9% vs. 40.7%), ideas of persecution (48.7% vs. 29.6%), depression (62.2% vs. 43.5%) and suicidal ideation in the previous year (50.7% vs. 24.3%). The present results suggest that additional program that prepared to care the drug addicts who experienced child abuse and are experiencing suicidal ideation is needed. Furthermore, intervention for families with risk factors for child abuse should be developed in order to prevent the victim from suffering not only from post traumatic stress disorder but also from substance related disorders.

Simultaneous bilateral femoral neck fractures are extremely rare and associated with various conditions. Up to now Most cases had correlations with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, anti-epileptic medications, seizure, etc. A 28-year-old addict man referred to us with a 10-year history of narcotic drug abuse and history of 8 months bilateral groin pain. He admitted with displaced bilateral femoral neck fracture. Because of long duration of this condition and osteonecrosis revealed on bone scan, one-staged bilateral hip hemiarthroplasty was done. A good function was noted after surgery to 4-month follow up. Up to now, have not be founded in the literature that a case of bilateral femoral neck fracture associated with narcotic drug abuse.Because of negative effects of opium or smoking on bone tissues, a simple bone pain should aware us about the risk of stress or fatigue fracture.
