Surgical Exposure Trends and Controversies in Extremity Fracture Care.

Surgical exposures for the management of extremity fractures continue to evolve. Strategies to achieve satisfactory articular reconstitution require surgeons to have an appreciation and understanding of various conventional and contemporary surgical approaches. The recent literature has witnessed a surge in studies on surgical approaches for the fixation of extremity fractures.

Heterogeneity of T Cell Responses to Pandemic pH1N1 Monovalent Vaccine in HIV-Infected Pregnant Women.

We investigated the Th1 protective and regulatory T and B cell (Treg and Breg) responses to pH1N1 monovalent influenza vaccine (IIV1) in HIV-infected pregnant women on combination antiretroviral therapy (cART). Peripheral blood mononuclear cells (PBMCs) from 52 study participants were cryopreserved before and after vaccination and analyzed by flow cytometry. pH1N1-specific Th1, Treg, and Breg responses were measured in PBMCs after in vitro stimulation with pH1N1 and control antigen.

Determinants of vaccine immunogenicity in HIV-infected pregnant women: analysis of B and T cell responses to pandemic H1N1 monovalent vaccine.

Influenza infections have high frequency and morbidity in HIV-infected pregnant women, underscoring the importance of vaccine-conferred protection. To identify the factors that determine vaccine immunogenicity in this group, we characterized the relationship of B- and T-cell responses to pandemic H1N1 (pH1N1) vaccine with HIV-associated immunologic and virologic characteristics. pH1N1 and seasonal-H1N1 (sH1N1) antibodies were measured in 119 HIV-infected pregnant women after two double-strength pH1N1 vaccine doses.

Commercial laboratory testing of excision repair cross-complementation group 1 expression in non-small cell lung cancer.

Excision repair cross-complementation group 1 (ERCC1) expression by non-small cell lung cancer (NSCLC) has been reported to predict resistance to platinum-based therapies. On this basis, several commercial laboratories have offered ERCC1 testing to facilitate clinical decision making, but the reliability of such assays has recently been called into question. Methods.

Growth of human immunodeficiency virus-infected children receiving highly active antiretroviral therapy.

Background: Weight and height growth of HIV-infected children tends to lag behind that of uninfected children of similar age. Previous reports of the effect of highly active antiretroviral therapy (HAART) on the growth of HIV-infected children have been contradictory.

Methods: Age- and gender-adjusted height and weight z scores were studied for 192 HIV-infected children, 4 months to 17 years of age, who had been treated with antiretroviral therapy for at least 16 weeks.

Safety and immunogenicity of a heptavalent pneumococcal conjugate vaccine in infants with human immunodeficiency virus type 1 infection.

Objective: Heptavalent pneumococcal conjugate vaccine (PCV) has been shown to be safe and effective in healthy infants and children. However, little is known about its use in children who have human immunodeficiency virus (HIV) infection and are known to be at increased risk of developing pneumococcal infections. This study was conducted to evaluate the safety and immunogenicity of heptavalent PCV in infants with HIV infection.

Growth in human immunodeficiency virus-infected children receiving ritonavir-containing antiretroviral therapy.

Background: Human immunodeficiency virus (HIV)-infected children often suffer from impaired growth. Highly active antiretroviral therapy (HAART) successfully reduces HIV 1 (HIV-1) RNA to 400 copies/mL or less in many children.

Objectives: To determine if age- and sex-adjusted growth z scores correlate with HIV-1 RNA level and if control of viral load for 48 and 96 weeks results in improved growth in children receiving highly active antiretroviral therapy.
