Abstract
This study explores associated factors and perceptions of oral health among crack users recruited in open drug scenes in Brazil. A mixed methods approach was used. The quantitative component analysed findings from a large (N = 7381), population-based survey. The outcomes under analysis were 'self-perception of oral health' and 'self-reporting of problems affecting the mouth, teeth and gingiva (gums)'. The qualitative component comprised a focus group, with 12 individuals recruited from a drug treatment clinic. Lower self-perception of oral health problems vis-à-vis a higher prevalence of problems affecting the mouth, teeth, and gingiva were found in users who had a lower level of education, used substances daily, had worse self-perception of physical health, did not receive health care and regularly used alcohol and/or tobacco. The results show an association between substance use and decline in oral health, as well as the lack of health services focusing on such issues. Oral health services should be emphasised as a gateway to the health system. So far, the putative cross-referral between services and professionals working in oral health and other health professionals working in the field of drug dependence has not been observed.

Abstract
BACKGROUND Crack cocaine use has increased rapidly throughout Mexico, coinciding with rising HIV and HCV infections among vulnerable groups. Due to the increased risk of infection among crack users, harm reduction approaches have been identified to reduce the spread of disease. However, Mexico has yet to adopt these techniques for crack users. OBJECTIVES To evaluate the impact of a pilot crack kit distribution program on risky smoking behaviors of active crack users in an impoverished colonia of Mexico City, Mexico. METHODS Fifty crack kits, containing safer smoking paraphernalia and related health items (i.e., condoms, alcohol wipes, etc.), were distributed to active crack users. A sample of 58 crack users were surveyed prior to the intervention and 35 were successfully relocated and surveyed three months after the intervention. Surveys assessed drug use, crack kit utilization, and smoking practices. RESULTS Findings indicate that crack kit utilization was high throughout the sample. Use of risky or unsafe paraphernalia decreased, specifically the use of cans as pipes (Z = -2.653, p = .008). Similarly, Pyrex pipe use increased significantly (Z = -3.132, p = .002). Sharing of paraphernalia also decreased throughout the sample. CONCLUSION These findings identify the potential benefits in reducing risky smoking behaviors of crack kit distribution programs in Mexico City. This evidence supports expansion of crack kit programs in Mexico and similar impoverished regions.

Abstract
OBJECTIVE to investigate the seroprevalence of hepatitis C in crack users in Piauí. METHOD seroepidemiological survey, undertaken in the Psycho-Social Care Centers for Drugs and Alcohol (CAPS AD) in Piauí in the period December 2011 to May 2012. A questionnaire was administered and blood samples were collected for serological research. Fisher's exact test and the Mann-Whitney test were used, with a level of significance of (p<0.05). RESULTS the prevalence of Anti-HCV was 05 (1.4%) and 04 (1.1%) for the RNA-HCV. There was a statistically significant association between hepatitis C (serological marker RNA-HCV) and age, being resident at home, length of use of crack, interruption of the use of crack, and the habit of sharing the crack pipes. CONCLUSION the findings support the need to implement health policies aimed at crack users, due to the accelerated process of physical and psychological deterioration to which these are subject.

Abstract
Abstract Aluminum (Al) is a ubiquitous substance encountered both naturally (as the third most abundant element) and intentionally (used in water, foods, pharmaceuticals, and vaccines); it is also present in ambient and occupational airborne particulates. Existing data underscore the importance of Al physical and chemical forms in relation to its uptake, accumulation, and systemic bioavailability. The present review represents a systematic examination of the peer-reviewed literature on the adverse health effects of Al materials published since a previous critical evaluation compiled by Krewski et al. (2007) . Challenges encountered in carrying out the present review reflected the experimental use of different physical and chemical Al forms, different routes of administration, and different target organs in relation to the magnitude, frequency, and duration of exposure. Wide variations in diet can result in Al intakes that are often higher than the World Health Organization provisional tolerable weekly intake (PTWI), which is based on studies with Al citrate. Comparing daily dietary Al exposures on the basis of "total Al"assumes that gastrointestinal bioavailability for all dietary Al forms is equivalent to that for Al citrate, an approach that requires validation. Current occupational exposure limits (OELs) for identical Al substances vary as much as 15-fold. The toxicity of different Al forms depends in large measure on their physical behavior and relative solubility in water. The toxicity of soluble Al forms depends upon the delivered dose of Al(+3) to target tissues. Trivalent Al reacts with water to produce bidentate superoxide coordination spheres [Al(O2)(H2O4)(+2) and Al(H2O)6 (+3)] that after complexation with O2(•-), generate Al superoxides [Al(O2(•))](H2O5)](+2). Semireduced AlO2(•) radicals deplete mitochondrial Fe and promote generation of H2O2, O2 (•-) and OH(•). Thus, it is the Al(+3)-induced formation of oxygen radicals that accounts for the oxidative damage that leads to intrinsic apoptosis. In contrast, the toxicity of the insoluble Al oxides depends primarily on their behavior as particulates. Aluminum has been held responsible for human morbidity and mortality, but there is no consistent and convincing evidence to associate the Al found in food and drinking water at the doses and chemical forms presently consumed by people living in North America and Western Europe with increased risk for Alzheimer's disease (AD). Neither is there clear evidence to show use of Al-containing underarm antiperspirants or cosmetics increases the risk of AD or breast cancer. Metallic Al, its oxides, and common Al salts have not been shown to be either genotoxic or carcinogenic. Aluminum exposures during neonatal and pediatric parenteral nutrition (PN) can impair bone mineralization and delay neurological development. Adverse effects to vaccines with Al adjuvants have occurred; however, recent controlled trials found that the immunologic response to certain vaccines with Al adjuvants was no greater, and in some cases less than, that after identical vaccination without Al adjuvants. The scientific literature on the adverse health effects of Al is extensive. Health risk assessments for Al must take into account individual co-factors (e.g., age, renal function, diet, gastric pH). Conclusions from the current review point to the need for refinement of the PTWI, reduction of Al contamination in PN solutions, justification for routine addition of Al to vaccines, and harmonization of OELs for Al substances.

Abstract
Human activities have circumvented the efficient geochemical cycling of aluminium within the lithosphere and therewith opened a door, which was previously only ajar, onto the biotic cycle to instigate and promote the accumulation of aluminium in biota and especially humans. Neither these relatively recent activities nor the entry of aluminium into the living cycle are showing any signs of abating and it is thus now imperative that we understand as fully as possible how humans are exposed to aluminium and the future consequences of a burgeoning exposure and body burden. The aluminium age is upon us and there is now an urgent need to understand how to live safely and effectively with aluminium.

Abstract
OBJECTIVE: To map treatment trajectories in a sample of male and female crack users through their narratives about the course of treatment seeking and their attempts to access health care services in Brazil. METHODS: Qualitative study of a purposive sample (five female and nine male hospitalized crack users) using semi-structured interviews. The interviews were transcribed and data explored using content analysis. RESULTS: Respondents reported difficulties getting access to hospitalization, relapse after discharge, and abandonment of treatment. There seems to be a peculiar model of behavior for women and men while dealing with craving for crack: while women got involved with prostitution and consequently became infected with HIV, every men of the sample reported criminal involvement. CONCLUSIONS: The relationship between relapse and a social environment conducive to consumption, associated with belief or disbelief in spiritual support, prostitution, and the legal complications arising from the use of crack, are relevant issues and should be taken into consideration in the development of preventive actions aimed at this specific population.

Abstract
Este estudo buscou avaliar a utilização da Intervenção Breve Motivacional (IBM) em um serviço de aconselhamento telefônico, oferecida aos jovens no processo de cessação do consumo de crack. Foi realizado um estudo descritivo, a partir do levantamento dos registros de ligações de usuários no período de janeiro de 2006 a dezembro de 2007. Foram incluídos 40 registros de chamadas de jovens com idades entre 16 e 24 anos que consumiam crack, associado ou não com outras substâncias. Ao final do acompanhamento no sexto mês, 65% dos jovens haviam parado o consumo de crack. Do total, 57,5% estavam no estágio de preparação e ação na primeira ligação. As chances para recaída do uso de crack foram maiores nos seguimentos até 30 dias. A partir dos resultados obtidos pode-se sugerir que, a IBM associada ao aconselhamento telefônico representa uma alternativa de tratamento importante na cessação do uso de crack.

Abstract
Several studies have shown a high prevalence of HIV-seropositive status among crack users, though most refer to North American populations. Few studies evaluate HCV prevalence among female crack users. In addition, there is a particular lack of data about risk behaviors and HIV/HCV prevalence in this population around the world. In order to ascertain the HIV/HCV serostatus and associated risk behaviors for infection of female crack users of Porto Alegre, Brazil. A cross-sectional study of a convenience sample of 73 current female crack users was conducted. Subjects answered NIDA's Risk Behavior Assessment and an AIDS Information Questionnaire. In addition, blood was collected from subjects for HIV/HCV tests. The overall prevalence of HIV was 37.0%; HCV seroprevalence was 27.7%; of 15.1% the sample was co-infected with HIV and HCV. Four years of schooling or fewer (OR 4.72-CI 95%; 1.49-14.99) and having three or more HIV tests in one's lifetime (OR 4.26-CI 95% (1.29-14.04)) were associated with HIV infection (after multivariate logistic regression). The single greatest risk factor for HCV infection was having 4 years of schooling or fewer (OR 4.51-CI 95%; 1.18-17.27). We found a very high prevalence of HIV and HCV infection among female crack users, and low education was the most significant risk factor associated with both infections.
