Chronic cryptococcal meningitis in an intravenous drug addict without evidence of infection by HIV-1,2 in southern Italy

Before the emergence of AIDS, extra-pulmonary cryptococcosis was very rare. By contrast, meningeal cryptococcosis is a very common opportunistic infection in AIDS patients. We report an intravenous drug addict with cryptococcal meningitis, who was not infected with HIV and had no apparent predisposing conditions. This case, as those elsewhere described, supports the potential existence of viral agents, other than HIV-1,2, capable of encouraging the occurrence of unusual infections as have emerged during the AIDS pandemic.     

Simultaneous Pulmonary Leiomyosarcoma and Leiomyoma in Pediatric HIV Infection

The case of a 7-year-old girl with acquired immunodeficiency syndrome treated for 5 years with AZT and intravenous gamma globulin is reported. Shortly before her demise she developed a pulmonary leiomyosarcoma and leiomyoma. Does prolonged survival in pediatric acquired immune deficiency syndrome increase the incidence of secondary malignancies?     

预防艾滋病健康教育媒体材料效果评价比较研究

目的评价4种预防艾滋病健康教育媒体材料的信息传播效果和材料效果。该材料由课题组于2003-2005年间设计制作，包括“艾滋病知识”折页、“了解艾滋病”海报、“预防艾滋病健康教育手册”和“认识艾滋病”宣教片等4种。方法2005年12月在珠海市选取小学以上文化程度的18～60岁外来工为测试对象，随机分组对4种材料分别进行评价，各调查了251、248、257和252人，共1008人。通过问卷调查了解受访者的一般情况和对材料信息的可接受性、通俗性和材料形式的生动性等8项指标的评价，采用分级定量赋分的方法进行量化评分，采用SPSS10．1统计软件进行统计分析、比较。结果4种材料的信息传播效果和材料效果总得分平均值分别为74．2±15．0、77．7±13．5、73．0±13．8和77．2±13．6，得分最高的是海报，为77．7±13．5分，最低的是手册，为73．0±13．8分，差异有统计学意义，这种差异主要体现在信息传播效果的差异，而材料效果的差异无统计学意义。通俗性、简明性、生动性和可接受性是影响得分高低的主要因素。结论海报是最适合用于城市外来工进行预防艾滋病健康教育的传播材料，其次是宣教片。     

IgE and atopy in perinatally HIV-infected children

Elevated serum immunoglobulin E (IgE) and increased prevalence of atopy is reported in patients infected with human immunodeficiency virus (HIV). The elevated serum IgE may be attributed to polyclonal stimulation of B cells or IgE production against allergens, viruses, fungi and bacteria. This study investigates the prevalence of atopy in perinatally HIV-infected children, and the relationships between serum IgE (and other serum immunoglobulins) with atopy, CD4+ cell count and HIV-disease stage. Serum immunoglobulin levels, epicutaneous skin test for common aeroallergens, clinical Centers for Disease Control and Prevention (CDC) classification, CD4+ cell counts and allergy history were extracted from the charts of perinatally HIV-infected children on highly active antiretroviral therapy. The prevalence of atopy (52%) and the pattern of aeroallergen sensitivity were comparable with the US pediatric population. Serum IgE levels did not correlate with clinical disease stage. However, in non-atopic patients, serum IgE levels increased with disease progression (p = 0.02). There was an inverse relationship between the prevalence of elevated serum IgE levels and atopy with progression of disease (p = 0.019). Serum IgE did not correlate with atopy, CD4+ cell count, or duration of HIV infection or levels of serum immunoglobulins. This is the first study to show no increased prevalence of atopy in perinatally HIV-infected children compared with the general population. In advanced stages of HIV, elevated serum IgE may be specific for antigens other than those known as allergens.     

Reproductive health knowledge and implications: A study in Nigeria

Forty-five percent of Nigeria's population is under age 15. This study employed a questionnaire to learn the level of reproductive health knowledge of 416 male and female Nigerian students ages 10 through 16.

The Chi-square statistical procedure was used as demographic characteristics were related to reproductive health knowledge among the pre-teen and teenage youth. Statistically significant (p #lt 0.05) relationships were found between variables such as knowledge of reproduction, family planning, and AIDS when each was compared separately to age, gender, living situation while at school, school club memberships, and so on. With respect to reproduction and related topics, older teenagers indicated more knowledge than pre-teenagers, girls more than boys, and those living in dormitories more than those living at home or in other housing while attending school.

Television ranked first in terms of students' sources of information on reproduction, pregnancy, birth control, and AIDS. Newspapers ranked second, radio third, teachers fourth, and parents fifth. Perhaps the most striking data are the “I don't know” responses with respect to AIDS. Thirteen percent had not heard of AIDS, 27 percent did not know how AIDS is transmitted, 29 percent did not know the seriousness of AIDS, 37 percent did not know how to avoid AIDS, and 14 percent did not know that a mother with AIDS might infect her baby. Recommendations are made for increasing health services and education concerning reproductive health for pre-teen and teenage students.     

Describing the health-related quality of life impact of HIV infection: Findings from a study using the HIV Overview of Problems—Evaluation System (HOPES)

This study aimed to describe the results of findings from data collected with an HIV-specific health-related quality of life tool, and to examine the relationship between clinical and biological factors and health-related quality of life (HRQL). Data were collected as a cross-sectional, patient-completed assessment of health-related quality of life. Laboratory data were abstracted from the medical chart. Patients (n=318) with HIV infection including asymptomatic (37%), ARC (20%), AIDS (25%), and AIDS with cancer (18%) were receiving health services at one of the medical centres serving HIV-infected patients in the Los Angeles community, including UCLA, community physicians, Veterans Affairs Medical Centers, and a county hospital. Additional data were contributed by the Johns Hopkins University Medical Center CMV Retinitis Clinic. Symptomatic patients and patients with the lowest CD4 counts reported poorer HRQL than asymptomatic patients and patients with higher CD4 counts. However, medical and demographic variables explained only 35% of the variability of HRQL ratings in this sample of HIV-infected patients. While clinical status and Karnofsky performance status may be used to estimate the impact of HIV infection on HRQL, they are not a substitute for independent assessment of HRQL by the patient.This research was funded in part by the UCLA AIDS Clinical Research Center and CARES Consultants.
