National attention continues to focus on the need to improve care for individuals with co-occurring mental illnesses and substance use disorders, as emphasized in the 2003 President's New Freedom Commission Report on Mental Health and recent publications from the Substance Abuse and Mental Health Services Administration (SAMHSA). These reports document the need for best practice recommendations that can be translated into routine clinical care. Although efforts are underway to synthesize literature in this area, few focused recommendations are available that include expert opinion and evidence-based findings on the management of specific co-occurring disorders, such as schizophrenia and addiction. In response to the need for user-friendly recommendations on the treatment of schizophrenia and addiction, a consensus conference of experts from academic institutions and state mental health systems was organized to 1) frame the problem from clinical and systems-level perspectives; 2) identify effective and problematic psychosocial, pharmacological, and systems practices; and 3) develop a summary publication with recommendations for improving current practice. The results of the consensus meeting served as the foundation for this publication, which presents a broad set of recommendations for clinicians who treat individuals with schizophrenia. "Integrated treatment" is the new standard for evidence-based treatment for this population and recommendations are given to help clinicians implement such integrated treatment. Specific recommendations are provided concerning screening for substance use disorders in patients with schizophrenia, assessing motivation for change, managing medical conditions that commonly occur in patients with dual diagnoses (e.g., cardiovascular disease, liver complications, lung cancer, HIV, and hepatitis B or C infections) and selecting the most appropriate medications for such patients to maximize safety and minimize drug interactions, use of evidence-based psychosocial interventions for patients with dual diagnoses (e.g., Dual Recovery Therapy, modified cognitive-behavioral therapy, modified motivational enhancement therapy, and the Substance Abuse Management Module), and key pharmacotherapy principles for treating schizophrenia, substance use disorders, and comorbid anxiety, depression, and sleep problems in this population. Finally the article reviews programmatic and systemic changes needed to overcome treatment barriers and promote the best outcomes for this patient population. An algorithm summarizing the consensus recommendations is provided in an appendix.

Injecting drug users (IDUs) are at risk of parenterally transmitted diseases such as hepatitis B virus (HBV) hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections. The present study was undertaken to find out the prevalence of HIV infection, HBV infection and HCV infection among IDUs of a deaddiction centre. Serum samples from 250, injecting drug users (IDUs) from a de-addiction centre were screened for HBsAg using immunochromatography, anti HCV antibody by 3rd generation ELISA test and anti HIV antibody by ELISA test and immunochromatographic rapid test during the period August to October 2002. One hundred and forty-nine (59.6%) IDUs were positive for HIV antibody, 226 (90.4%) were positive for anti HCV antibody and 27 (10.8%) were positive for HBsAg. There was co-infection of HIV, HBV and HCV in 15 (6%) of the IDUs. The Co-infection of HBV and HCV were found in 12 cases (4.8%) and Co-infection of HIV and HCV was found in 131 cases (52.4%). The IDUs were in sexually active age group with a risk of infection to their sexual partner. There is high prevalence of HCV and HIV infection and co-infection of both viruses among IDUs. Comprehensive public health interventions targeting this population and their sexual partners must be encouraged. Increase coverage of needle, syringe exchange programme (NSEP) to young and new IDUs is required before they are exposed to blood borne viruses.

The case-control study was conducted among addicts in Alexandria to determine the different health problems among them, as well as to study the correlation between addiction and these problems. One hundred drug addicts and eighty apparently healthy controls were included in this study. The whole sample was subjected to the following: filling a predesigned questionnaire sheet, clinical and electrocardiogram (ECG) examination, measurements of Body Mass Index (BMI), complete blood picture and antistreptolysin O titre (ASO), testing for hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (anti HBc), skin scrapings from superficial fungal lesions in addition to complete urine and stool examination. The results revealed that chest rhonchi, hepatomegaly, central nervous system (CNS) abnormalities, skin lesions lymphadenopathy, underweight and anaemia were significantly higher among addicts than the controls. Hepatitis B virus (HBV) exposure and HBsAg seropositivity were found 48.0% and 21.0%, respectively among addicts compared to 26.3% and 5.0%, respectively among the controls. The intravenous injections and tattooing were the most risky routes for HBV infection among addicts. A positive correlation was revealed between HBV exposure and both the duration and the number of daily injections. Chest X-ray suggestive of pulmonary tuberculosis were found in 7.0% of the addicts. Addiction potentiated the risk of fungal infection among low social class, but it had no effect on the relationship between anaemia and social class nor on that between loss of appetite and underweight.

Liver biopsy specimens were morphologically investigated in 87 patients, including 30 with drug (marijuana and poppy straw) addiction, 23 with chronic alcoholic intoxication, and 25 abused narcotics and alcohol concomitantly. All the patients were not found to be infected with viruses of hepatitis B, C, G, TTV, or CMN; the clinical manifestations and biochemical blood parameters were studied over time. In patients who simultaneously used drugs and alcohol, the specific features of hepathopathy were shown to be more pronounced and more rapidly progressive changes as fatty hepatosis and diffuse liver tissue fibrosis than in those used either drugs alone or alcohol alone. This is favored by chronic inflammation and cholestasis that is accompanied by bile duct proliferation. Concomitance of these processes leads to permanent liver tissue atrophy and death and to the relatively early development of hepatic monolobular cirrhosis. The mechanisms responsible for the patho- and morphogenesis of combined toxic hepatopathy are discussed.

Addiction is a chronic relapsing disorder characterized by repetitive and compulsive drug-seeking behavior and drug abuse despite negative health or social consequences. Cocaine addiction is a significant worldwide public health problem, which has somatic, psychological, psychiatric, socio-economic and judicial complications. Some of the most frequent complications are cardiovascular effects (acute coronary syndrome, cardiac arrhythmias, increased blood pressure); respiratory effects (fibrosis, interstitial pneumonitis, pulmonary hypertension, alveolar haemorrhage, asthma exacerbation; emphysema), neurological effects (strokes, aneurysms, seizures, headaches); risk for contracting HIV/AIDS, hepatitis B and C, sexual transmitted disease and otolaryngologic effects. Other complications are not discussed here. The vast majority of studies indicate that there are cognitive deficits induced by cocaine addiction. Attention, visual and working memories, executive functioning are affected in cocaine users. Psychiatric complications found in clinical practice are major depressive disorders, cocaine-induced paranoia, cocaine-induced compulsive foraging and panic attacks.

Homeless people are usually prone to be infected with multiple infectious diseases such as human immunodeficiency virus, hepatitis B virus, and hepatitis C virus, as well as syphilis. In this cross-sectional study, using a questionnaire and enzyme-linked immunosorbant assay, we evaluated the seroprevalance of hepatitis B and C viruses, human immunodeficiency virus, and syphilis, as well as their risk factors in 202 homeless men. A total of 70 (34.7%), 87 (42.8%), and 13 (6.4%) subjects were infected with hepatitis B, hepatitis C and human immunodeficiency viruses, respectively. Ten (0.5%) had a simultaneous infection with hepatitis B and C viruses and human immunodeficiency virus. Only one participant was seropositive for rapid plasma reagin. History of smoking and opium addiction was present in 144 (71.6%) and 109 (54.2%) subjects, respectively. Although all human immunodeficiency virus-positive subjects were hepatitis C virus positive, 10 (76.9%) had a history of intravenous drug abuse. Risk factors including intravenous drug abuse (P<0.005) and imprisonment (P<0.05) were significantly associated with all the three infections. We found no significant association between high-risk sexual behavior and these infections. Although syphilis seems not to be an important risk factor among homeless adults, all hepatitis B, hepatitis C, and human immunodeficiency virus infections have quite noticeable frequencies among Iranian subjects. History of intravenous drug abuse should be taken into account in screening of homeless people.

The global spread of hepatitis B virus (HBV) and hepatitis C virus (HCV), their high chronicity rates and their progression to cirrhosis and hepatocellular carcinoma, are major public health problems. Research and intervention programmes for special population groups are needed in order to assess their infection risk and set up suitable prevention and control strategies. Aim of this paper is to give health care professionals information on HBV and HCV infections amongst migrants, drug users and prison inmates. The manuscript is an official Position Paper on behalf of the following Scientific Societies: Italian Association for the Study of the Liver (A.I.S.F.), Italian Society of Infectious and Tropical Diseases (S.I.M.I.T.), Italian Federation Department's Operators and Addiction Services (FederSerD), Italian Prison Medicine and Healthcare Society (S.I.M.S.Pe.). The considered population groups, having a high prevalence HBV and HCV infections, require specific interventions. In this context, the expression "special population" refers to specific vulnerable groups at risk of social exclusion, such as migrants, prison inmates, and intravenous drug users. When dealing with special population groups, social, environmental and clinical factors should be considered when selecting candidates for therapy as indicated by national and international guidelines.

This purpose of this study was to determine prevalences and risk factors associated with infection by human immunodeficiency virus, hepatitis B Virus, syphilis and bacillary pulmonary tuberculosis in prisons in Burkina Faso. From February 20 to March 20, 2009, 300 prisoners over 18 years of age held in Ouagadougou were selected to take part in this descriptive and analytical cross-sectional study. Sociodemographic data, confinement information (number, motive and prison time), medical history, substance addiction (alcohol, tobacco, drug), and the other risk behaviors (sexual relations, type of partners, sharing of toiletries or razor) were compiled for each prisoner. Serological tests were performed to detect anti-HIV antibodies, Hbs antigen, and anti-treponema antibody. In prisoners presenting signs of tuberculosis, BAAR detection was performed by direct examination of sputum. Men represented 95% of the study population. Median age was of 30.1 +/- 8.9 years (range, 18 and 63). The prevalences of HIV infection, Hbs antigen and positive syphilitic serology were 5%, 27.3% and 5.7% respectively. Four prisoners (1.3%) had bacillary pulmonary tuberculosis. Two prisoners reported homosexual intercourse and 44 reported drug abuse. Sharing of toiletries and razor blades was reported by 18.7% and 20% of the prisoners respectively. Immediate measures are needed reduce the spread of these infections in prisons in Africa.

Heroin is an illicit, highly addictive drug. It is either the most abused or the most rapidly acting member of opioids. Abusers describe a feeling of a surge of pleasurable sensation, named as "rush" or "high". Repeated administration of high doses of heroin results in the induction of physical dependence. Physical dependence refers to an altered physiological state produced by chronic administration of heroin which necessitates the continued administration of the drug to prevent the appearance of a characteristic syndrome, the opioid withdrawal or abstinence syndrome. Withdrawal symptoms may occur within a few hours after the last administration of heroin. Symptoms of the withdrawal include restlessness, insomnia, drug craving, diarrhea, muscle and bone pain, cold flashes with goose bumps, and leg movements. Major withdrawal symptoms peak between 48 and 72 hours after the last dose of heroin and subside after about a week. At this time, weakness and depression are pronounced and nausea and vomiting are common. Nevertheless, some chronic addicts have shown persistent withdrawal signs for many months or even years. Heroin addiction is considered as a behavioural state of compulsive drug use and a high tendency to relapse after periods of abstinence. It is generally accepted that compulsive use and relapse are typically associated with the status of heroin craving or heroin hunger that are difficult to define but appear to be powerful motivational significance in the addiction process. The route of administering heroin varies largely and may indicate the degree of seriousness of the individual's addiction. Intravenous administration seems to be the predominant method of heroin use, but recently a shift in heroin use pattern has been found, i.e. from injection to sniffing and smoking. Frequent injections coupled with widespread sharing of syringes increase the risk of contracting HIV, hepatitis B, C and other blood-borne infectious diseases. Long-term use of heroin has also severe medical consequences such as scarred veins, bacterial infections of blood vessels, liver and kidney diseases, and lung complications.

What do I as a critical care nurse do? Nurses, by virtue of being trained in health promotion, and also because they interact with patients, families, and communities, have firsthand opportunities to play an active role in practicing primary prevention. To avoid the first occurrence of substance abuse, assess community need, assess facility needs, and identify potential risk. Identify the magnitude of the problem. Intervene early with the youth and at-risk populations. Refer patients and their families to mental health specialists. Provide education to patients, families, communities. To reduce occurrences of substance abuse, practicing secondary prevention requires prompt action in the earliest moments of recognizing a problem and directing patients to early intervention and rehabilitation. Screening your patients, providing brief education, and prompt referral constitutes early intervention. To retard the progress of the disease, practice tertiary prevention by providing education, counseling, and support to the afflicted in achieving and maintaining sobriety through medication compliance and rehabilitative group and counseling work. The goal of intervention in the lives of substance abusers is to stop drug use, avoid relapse, and sustain recovery. After years of research, NIDA has identified 13 fundamental principles to effective drug abuse treatment. 1. Addiction is a complex but treatable disease that affects brain function and behavior. 2. No single treatment is appropriate for everyone. 3. Treatment needs to be readily available. 4. Effective treatment attends to multiple needs of the individual, not just his or her drug abuse. 5. Remaining in treatment for an adequate period of time is critical. 6. Counseling--individual and/or group--and other behavioral therapies are the most commonly used forms of drug abuse treatment. 7. Medications are an important element of treatment for many patients, especially when combined with counseling and other behavioral therapies. 8. An individual's treatment and services plan must be assessed continually and modified as necessary to ensure it meets his or her changing needs. 9. Many drug-addicted individuals also have other mental disorders that need treatment. 10. Medically assisted detoxification in the first stage of addiction treatment and by itself does little to change long-term drug abuse. 11. Treatment does not need to be voluntary to be effective. 12. Drug use during treatment must be monitored continuously, because lapses during treatment do occur. 13. Treatment programs should assess patients for the presence of HIV/AIDS, hepatitis B and C, tuberculosis, and other infectious diseases, as well as provide targeted risk-reduction counseling to help patients modify or change behaviors that place them at risk of contracting or spreading infectious diseases. To truly impact this disease, there needs to be improvement in the identification of risk factors and early identification and early intervention with children and adolescents. The future of neuroscience is in objective brain scans and genetic testing. Out of these approaches can come more objective measures of addiction and dependence using brain scans and genetic testing. These measures would potentially allow for the development of vaccines for specific drugs of abuse and dependence, as well as increasingly selective and effective pharmacologic approaches for treatment and a new consensus on standard of care for substance dependence.
