OBJECTIVES. During the severe acute respiratory syndrome outbreak of 2003, there was an impetus to provide clinical information to the medical community in a timely manner. Accordingly, a preliminary report of our experience of suspected severe acute respiratory syndrome-associated coronavirus infections in children was published without microbiological findings. This report provides an update on pediatric severe acute respiratory syndrome-associated coronavirus infections in Toronto, Ontario, Canada, that includes microbiological findings. METHODS. All of the children admitted to the Hospital for Sick Children between March 14 and June 15, 2003, with suspect severe acute respiratory syndrome-associated coronavirus infection were included. A proven case was defined as one that fulfilled the clinical criteria for suspect severe acute respiratory syndrome-associated coronavirus infection and demonstrated a serologic response to severe acute respiratory syndrome-associated coronavirus. Serology results, from a neutralizing antibody assay, were considered positive if the sera inhibited the development of a severe acute respiratory syndrome-associated coronavirus-specific cytopathic effect at a dilution of ⩾1:8. RESULTS. Neutralizing antibody to severe acute respiratory syndrome-associated coronavirus was demonstrated in 8 of 25 children admitted with suspect severe acute respiratory syndrome-associated coronavirus infection. In 3 of these 8 children, severe acute respiratory syndrome-associated coronavirus was also detected by reverse-transcription polymerase chain reaction in the stool. All 8 had documented exposure to ⩾ 1 severe acute respiratory syndrome-associated coronavirus-infected adults residing in the same household. Exposure that was limited to visiting a Toronto hospital at which severe acute respiratory syndrome-associated coronavirus-infected patients were admitted or travel from a country in which severe acute respiratory syndrome had been reported did not result in documented infection in any of our cases. On the basis of our clinical case definition, 6 of 8 microbiologically confirmed case had been classified as having probable severe acute respiratory syndrome-associated coronavirus infection. Clinical disease was mild, nonspecific, and self-limited and was indistinguishable from that reported with other common respiratory viruses. CONCLUSIONS. The factor most strongly associated with severe acute respiratory syndrome-associated coronavirus infection in Toronto children was a history of close contact with an adult severe acute respiratory syndromeassociated coronavirus case. This serves to reinforce the importance of routinely obtaining a thorough epidemiologic travel and exposure history for all subjects with suspected infectious diseases. [ABSTRACT FROM AUTHOR]

Objective. An outbreak of severe acute respiratory syndrome (SARS) occurred in the greater Toronto area between February and June 2003. We describe the clinical, laboratory, and epidemiologic features of children who were admitted to the Hospital for Sick Children, Toronto, with a presumptive diagnosis of suspect or probable SARS. Methods. A prospective investigational study protocol was established for the management of children with a presumptive diagnosis of suspect or probable SARS. All were ultimately classified as having probable SARS, suspect SARS, or another cause on the basis of their epidemiologic exposure, clinical and radiologic features, and results of microbiologic investigations. Results. Twenty-five children were included; 10 were classified as probable SARS and 5 were classified as suspect SARS, and in 10 another cause was identified. The exposure consisted of direct contact with at least 1 adult probable SARS case in 11 children, travel from a World Health Organization-designated affected area in Asia in 9 children, and presence in a Toronto area hospital in which secondary SARS spread had occurred in 5 children. The predominant clinical manifestations of probable cases were fever, cough, and rhinorrhea. With the exception of 1 teenager, none of the children developed respiratory distress or an oxygen requirement, and all made full recoveries. Mild focal alveolar infiltrates were the predominant chest radiograph abnormality. Lymphopenia; neutropenia; thrombocytopenia; and elevated alanine aminotransferase, aspartate aminotransferase, and creatine kinase were present in some cases. Nasopharyngeal swab specimens were negative for the... [ABSTRACT FROM AUTHOR]

In Canada, there is a paucity of research aimed at understanding Black gay men and the antecedents to risk factors for HIV. This study is an attempt to move beyond risk factor analysis and explore the role of sexual and ethnic communities in the lives of these men. The study utilized a community-based research and critical race theory approach. Semi-structured interviews were conducted with eight key informants to augment our understanding of Black gay men and to facilitate recruitment of participants. In-depth interviews were done with 24 Black gay men. Our data showed that the construction of community for Black gay men is challenged by their social and cultural environment. However, these men use their resilience to navigate gay social networks. Black gay men expressed a sense of abjuration from both gay and Black communities because of homophobia and racism. It is essential for health and social programmers to understand how Black gay men interact with Black and gay communities and the complexities of their interactions in creating outreach educational, preventive and support services.

Objective: To evaluate whether the length of time of rupture of membranes (ROM) in optimally managed HIV-positive women on highly active antiretroviral therapy (HAART) with low viral loads (VL) is predictive of the risk of mother to child transmission (MTCT) of the human immunodeficiency virus (HIV)., Study Methods: A retrospective case series of all HIV-positive women who delivered at two academic tertiary centers in Toronto, Canada from January 2000 to November 2010 was completed., Results: Two hundred and ten HIV-positive women with viral loads <1,000 copies/ml delivered during the study period. VL was undetectable (<50 copies/mL) for the majority of the women (167, 80%), and <1,000 copies/mL for all women. Mode of delivery was vaginal in 107 (51%) and cesarean in 103 (49%). The median length of time of ROM was 0.63 hours (range 0 to 77.87 hours) for the entire group and 2.56 hours (range 0 to 53.90 hours) for those who had a vaginal birth. Among women with undetectable VL, 90 (54%) had a vaginal birth and 77 (46%) had a cesarean birth. Among the women in this cohort there were no cases of MTCT of HIV., Conclusions: There was no association between duration of ROM or mode of delivery and MTCT in this cohort of 210 virally suppressed HIV-positive pregnant women.

We describe the experiences of a sample of Canadian HIV+ youth whose intact adolescent identities contrast sharply with the expected identity challenges of persons living with a serious, chronic disease. We first showcase the positive HIV+ identities emerging from the successful management of HIV+ status through long-term HIV-related medical care and established pharmaceutical regimes. Second, we describe the medical, familial, and broader social context of support in which these adolescents' are negotiating HIV. Finally, we highlight the youth's expectations of future, specific identity and role challenges regarding intimacy and sexuality-related to disclosure of their private HIV+ identities and their embodied HIV+ status. Continued social and medical supports will be key to their emergence into adulthood as healthy HIV+ persons; with such supports, these youths' experiences highlight the capacity for living optimally with HIV.

Background: Limited data are available on disease characteristics and outcomes of children with 2009 pandemic influenza A(H1N1) virus infection (pandemic H1N1 influenza) who have required hospital admission., Methods: We reviewed the charts of 58 children with pandemic H1N1 influenza admitted to a large pediatric hospital in Ontario, Canada, between May 8 and July 22, 2009. We compared risk factors, severity indicators and outcomes of these children with those of 200 children admitted with seasonal influenza A during the previous 5 years (2004/05 to 2008/09)., Results: Children with pandemic H1N1 influenza were significantly older than those with seasonal influenza (median age 6.4 years v. 3.3 years). Forty-six (79%) of the children with pandemic H1N1 influenza had underlying medical conditions; of the other 12 who were previously healthy, 42% were under 2 years of age. Children admitted with pandemic H1N1 influenza were significantly more likely to have asthma than those with seasonal influenza (22% v. 6%). Two children had poorly controlled asthma, and 6 used inhaled medications only intermittently. The median length of stay in hospital was 4 days in both groups of children. Similar proportions of children required admission to the intensive care unit (21% of those with pandemic H1N1 influenza and 14% of those with seasonal influenza) and mechanical ventilation (12% and 10% respectively). None of the children admitted with pandemic H1N1 influenza died, as compared with 1 (0.4%) of those admitted with seasonal influenza., Interpretation: Pandemic H1N1 influenza did not appear to cause more severe disease than seasonal influenza A. Asthma appears to be a significant risk factor for severe disease, with no clear relation to severity of asthma. This finding should influence strategies for vaccination and pre-emptive antiviral therapy.

Background: AIDS is one of the biggest health crises we face today. With nearly 20 million women infected with the virus that causes it, HIV, maternal transmission of HIV is increasingly becoming a serious concern and hindrance in stemming the proliferation of the disease. While an ever increasing number of pregnant women are being administered anti-retrovirals to mitigate the vertical transmission of the virus, little is known about the changing trends in the type of agents used and the duration of therapy., Objectives: This paper attempts to identify any changes in the pattern of HIV management in pregnant women for the period of time spanning 1998 to 2005., Methods: Data from the charts of 183 patients were reviewed. A retrospective, longitudinal and cross-sectional patient chart review was employed to obtain data. Parameters such as therapeutic management of HIV, class of drugs used and duration of treatment were assessed to identify any evolving patterns over the course of the study., Results: It was seen that over time, the number of women receiving adequate therapeutic interventions has steadily increased. We also identified evolving trends in terms of the classes of anti-retrovirals employed and the duration of prophylaxis., Conclusion: The strategies employed in the management of HIV positive pregnancies in Ontario, while evolving over time, were found to be in line with the guidelines in place. The information delivered by this study might enable the medical community to assess the progress in dealing with this challenge thus far and further fine tune the current strategy.

Background: Globally, half of all new HIV infections occur among youth under 25. As of June 30, 2002, more than 13,000 youth and young adults had tested positive for HIV in Canada. Despite this prevalence, there is a lack of resources for Canadian HIV-positive youth., Objective: To investigate what can be done to better support the needs of HIV-positive youth in Canada., Methods: A community-based participatory research approach was adopted. Thirty-four qualitative in-depth semi-structured interviews were conducted with youth (ages 12-24) living with HIV in Ontario. A stakeholder group of youth living with HIV, professionals and researchers collaboratively analyzed the data for emerging themes., Results: When asked about areas in their lives where youth needed support, three major themes emerged: 1) Personal feelings about HIV: Youth identified a wide range of emotional response to their HIV status; however feelings of isolation, loneliness and hopelessness were dominant. 2) Barriers to full participation in society: Youth described a number of social and structural barriers to their full participation in society. 3) Specific support needs: Youth had difficulty accessing appropriate support services; they had very mixed feelings about both youth- and AIDS-serving organizations., Interpretation: The youth we interviewed are interested in targeted programs, have difficulty accessing appropriate resources and would benefit greatly from increased social support. Specialized health and support services that are developmentally appropriate may be necessary. Where specialized services do exist, more research may be necessary to understand why they are underutilized and/or perceived as inappropriate. While this was a small exploratory study, our data suggest that better supporting the needs of HIV-positive youth might directly benefit this vulnerable population.
