Na imunodeficiência comum variável (ICV) têm sido descritas alterações de linfócitos T, incluindo a produção diminuída da interleucina-2 (IL-2). Desde que a IL-2 pode promover a produção de imunoglobulinas in vitro, nosso principal objetivo foi investigar os efeitos in vivo do tratamento com IL-2 recombinante (IL-2r) em pacientes com ICV. Foram selecionados 4 pacientes que apesar de tratamento adequado com imunoglobulina EV apresentavam infecções recorrentes. Após um período de observação de 12 meses, os pacientes receberam doses crescentes de IL-2r durante 16 semanas com reposição de imunoglobulina apenas se a IgG sérica atingisse níveis menores do que 400mg/dL. A seguir, permaneceram em observação por mais 12 meses recebendo imunoglobulina . A gravidade das infecções foi avaliada segundo um \"score\" numa escala de 3 a 10. A avaliação in vitro incluiu: quantificação dos níveis de IgG, IgA e IgM séricas; resposta linfoproliferativa à PHA; populações linfocitárias CD4+, CD8+, CD19+ e CD25+ no sangue periférico. As reações adversas à IL-2r foram leves e localizadas. Houve redução aparente do número e gravidade das infecções durante os 12 meses subseqüentes ao término da IL-2r. Os níveis da IgG sérica e das células CD4+, CD8+ e CD19+ mantiveram-se estáveis durante todo o estudo. Em 3 pacientes houve relação entre melhora clínica e aumento da proporção de linfócitos T CD25+. Isto permite supor que a remissão de infecções em alguns pacientes com ICV , sob terapêutica com IL-2r associada ou não à imunoglobulina EV, esteja parcialmente relacionada à melhora da imunidade celular. Adicionalmente, nossos dados indicam que a IL-2r pode ser utilizada de modo seguro nas dosagens e período utilizados como terapêutica adjuvante em alguns pacientes com ICV que apresentam infecções recorrentes e má resposta terapêutica à imunoglobulina endovenosa / In Common Variable Immunodeficiency (CVID) T cell function may be impaired and interleukin-2 (IL-2) production diminished. Since IL-2 stimulates immunoglobulin production in vitro, the aim of this study was to determine the in vivo effects of recombinant interleukin-2 (rIL-2) in patients with CVID. We selected four CVID patients, who despite intravenous immunoglobulin infusion (IVIG) had recurrent infections. After a twelve-month run-in period, escalating dosages of rIL-2 were administered during 16 weeks, during which rescue IVIG treatment was performed whenever serum IgG levels dropped below 400 mg/dL. During follow-up (12 months), patients were observed and treated with IVIG. Infection severity was assessed using a 3 to 10 infection score. In vitro analysis included: measurement of serum levels of IgG, IgA and IgM; lymphocyte proliferative responses to phytohaemaglutinin (PHA); CD4+, CD8+,CD19+ and CD25+ lymphocyte populations in peripheral blood. Few local side-effects were observed in 2 patients. In the follow-up period after rIL-2 treatment, patients experienced reduction of the number and severity of infections. Levels of serum IgG, CD4+, CD8+ and CD19+ were stable throughout the study. In 3 patients we observed a relation between improvement of clinical parameters and number of T CD25+ cells. These findings suggest that remission of infections in some CVID patients treated with rIL-2, in combination or not with IVIG is, in part, associated with the improvement of cell immunity. Additionally, our results indicate that rIL-2 administration is safe and may serve as adjuvant therapy in some CVID patients with recurrent infections and poor response to IVIG treatment

(EN) Home parenteral nutrition (DPV) has become a routine part of patients care whose oral intake is reduced or completely eliminated. An integral part of the application of DPV is also the permanent or temporary need for functioning vascular access. Catheter complications negatively affect the quality of life, morbidity and in case of catheter sepsis the patient mortality. In addition it also brings increased costs for therapy and the need for patients re-hospitalization. The main objective of our study is to analyze catheter-related complications and to determine whether use of catheter plugs like TauroLock and TauroLock Hep and Tegaderm CHG antimicrobial dressing affect the incidence of catheter complications with DPV, and whether the incidence of complications is affected by a person who treated the catheter. The secondary objective is to characterize patients with served DPV and types of catheter used for this purpose.The method chosen is a retrospective observational cohort study. The study contains 52 patients with 72 catheters (39 Broviac, 18 PICC and 15 ports). The monitored number of catheter- days in total was 33,875. We conclude that the use TauroLock Hep is effective in the prevention of catheter complications and significantly reduces the overall incidence of all complications (p =...

This thesis evaluated the effects of two types of training on nurses’ ability to safely and efficiently administer IV medications using a smart infusion pump. A high fidelity simulated nursing unit was created in which nurses recruited from the University Health Network programmed a series of infusions after receiving training. A training script modeled after the pump vendor’s training sessions was created and tested first on 24 nurses. The results were analyzed for deficiencies in safety and efficiency from a human factors and education perspective and a new training script was created and tested on a group of 23 nurses. No significant differences were found between training groups on measures related to safety, but significant differences were found in nurse efficiency and behaviour in some aspects of pump programming. This study sets a precedent for human factors evaluation being used in tandem with existing training practices and lays the groundwork for further exploration on this topic.

Background: Functional imaging studies have examined the neural circuitry of subjects with obsessive compulsive disorder (OCD), and the changes associated with oral treatment. However, the effect of intravenous (IV) serotonin reuptake inhibitors (SRIs) on neuronal activation has not been investigated in OCD subjects, even though IV SRIs have been shown to be more effective than oral pharmacotherapy. Methods: Six OCD and 6 control subjects underwent functional magnetic resonance imaging while receiving infusions of citalopram and placebo, in a randomized, crossover design. Results: Compared to controls, OCD subjects exhibited hyperactivation of the orbitofrontal cortex and anterior cingulate cortex while looking at symptom provoking pictures at baseline. However, after the citalopram infusion, patients displayed attenuations of these regions, which correlated with reductions in subjective anxiety ratings. Conclusion: The effects observed after the IV citalopram infusion are similar to modulations observed after prolonged oral pharmacotherapy trials, illustrating the benefits of IV SRIs.

Since the onset of the AIDS (Acquired Immunodeficiency Syndrome) crisis in 1982, Aboriginal women have been contracting HIV (Human Immunodeficiency Virus) and Hepatitis C in increasing numbers. A new Aboriginal HIV/AIDS research agenda is imperative. This research was conducted in an attempt to understand why Aboriginal women in Saskatchewan remain marginalized in their continuing struggle against HIV/AIDS and Hepatitis C. Through the use of in-depth ethnographic profiles and personal histories, twenty-two Aboriginal women from Saskatchewan candidly shared their life histories. The women were asked a range of questions, including their knowledge about HIV/AIDS and Hepatitis C, and their attitudes and behaviours concerning sexual activities, alcohol and drug use, education, health, and lifestyle. The key issues for Aboriginal women with HIV/AIDS and/or Hepatitis C focus on the fact that they sustain triple jeopardy, in that they are discriminated against for having HIV/AIDS and/or Hepatitis C, for being a minority population by virtue of their Aboriginal ancestry, and for being women. Any analyses of what makes Aboriginal women vulnerable to HIV and Hepatitis C infection must take into account the role of poverty, independent of any risk factors, in leading to infection, illness, and in some instances, death. The majority of the respondents were found to be prostitutes who continued to be involved in street prostitution, even after they had been diagnosed with HIV and/or Hepatitis C. Twenty percent of the respondents were infected through unprotected sexual activity, 20% through intravenous drug use, and 60% were infected through both unsafe sex and intravenous drug use. The results of this research the incidence of both HIV and Hepatitis C is high in Aboriginal communities in Saskatchewan, due largely to low condom use, high rates of STDs (sexually transmitted diseases), low self-esteem, a lack of self-identity, increasing intravenous drug use, violence, sexual abuse, and high representation in street prostitution. Research to date is inadequate to the task of preventing the further spread of HIV and/or Hepatitis C, and providing effective and culturally appropriate treatment to Aboriginal women in Saskatchewan. This thesis serves to fill some of the research gap in knowledge about the relationship between race, gender, social class, sexual behavior and HIV/AIDS and/or Hepatitis C infection.

<p>In this case study research project I have determined that multidrug sedation in children younger than eight years are possible.<br /> Conscious sedation [or sedation where verbal contact with the patient is possible] can be used successfully to decrease anxiety and fear for unpleasant experiences, like dental procedures.</p> <p><br /> Behaviour therapy in conjunction with one or more drugs can be used to depress the central nervous system in order to decrease the patient&rsquo / s awareness of unpleasant stimuli. This enables treatment to be carried out without patient interference. Extensive literature surveys were done to determine the ideal drugs as well as the ideal route for conscious sedation in dental treatment for children. In this study project drugs like midazolam, propofol, alfentanyl and ketamine were titrated intravenously to achieve conscious sedation.</p>
