Influenza vaccination: a collaborative effort to improve the health of the community.

BACKGROUND: The need to improve influenza vaccination delivery in our community became painfully clear during the winter of 1997-1998 when high rates of respiratory illness led to congestion in the emergency department and a critical shortage of hospital beds. In response, the local hospital and the Department of Health launched a collaborative program to increase influenza vaccine coverage in the community. METHODS: The partnership was designed to increase the number of citizens receiving influenza vaccine and to moderate the severity of lower respiratory tract illness during the winter season. A variety of methods were used to increase public awareness, enhance vaccine delivery, and create a relatively seamless service for the community. RESULTS: During three seasons, influenza vaccination rates increased by a relative 150%. This represented immunization of 16% of the entire community and more than 75% of residents older than 65 years. Hospital employee vaccination rates also rose from 34% to 58%. When compared with other hospitals in the county, the campaign reduced the average number of annual visits to the emergency department for all respiratory diagnoses by 34% and exacerbations of chronic obstructive pulmonary disease by 46%. CONCLUSIONS: This influenza vaccination program illustrates the potential for synergy that exists between local departments of health and community hospitals in successfully increasing vaccine delivery to the community. Furthermore, it also suggests that such efforts can be successful in reducing use of the emergency department, resulting in a positive impact on the health of the community.     

Second neoplasms in survivors of childhood and adolescent cancer are often treatable.

PURPOSE: To estimate the incidence and types of second neoplasms in survivors of childhood and adolescent cancer, as well as the characteristics of those who developed second neoplasms. METHODS: Survivors who were under age 21 years at initial diagnosis, off therapy, and in remission for 2 years are referred to the Long Term Survivors' Clinic (LTSC) at Children's National Medical Center (CNMC). This review includes patients entered in the clinic database from January 1, 1997 to August 30, 2002. RESULTS: Twenty-three (2.3%) of 987 childhood cancer survivors followed in the LTSC had 26 (2.6%) second and third neoplasms. The mean age was 6.7 years at initial diagnosis, 20.3 years at diagnosis of the second neoplasm, and 20.5 years at diagnosis of the third neoplasm. Of 10 female and 13 male patients, 15 were white, six black, one Hispanic, and one Asian. All but two of the patients received radiation. Nineteen neoplasms, including seven thyroid carcinomas, six central nervous system tumors (three meningiomas), three basal cell carcinomas, two breast cancers, and one soft tissue sarcoma, occurred at sites within or contiguous to radiation sites. Five patients died, but the majority of neoplasms were treatable and most patients had good outcomes. CONCLUSION: Indefinite follow-up in a long-term survivors' clinic is indicated for adolescent and adult survivors of childhood cancer, with routine examination and screening for recurrence of the initial cancer as well as late effects, including second neoplasms.     

Heightened vulnerability and increased risk-taking among adolescent chat room users: results from a statewide school survey.

PURPOSE: To profile adolescent Internet chat room users in terms of demographic characteristics, psychological and environmental factors, and behavioral risk factors. METHODS: The study sample was drawn from respondents to an anonymous statewide survey of 50,168 9th-grade public school students and included 40,376 students who reported Internet access at home and 19,511 who accessed chat rooms. Data were collected by the Minnesota Student Survey (MSS), a survey that has been administered triennially by the state's education department to public school students in grades 6, 9, and 12 since 1989. The MSS includes more than 117 questions (300 variables) addressing attitudinal, behavioral, and environmental issues. Data analysis consisted of comparing the odds of a particular characteristic or behavior for chat room users with that of nonusers. Analyses were run separately for boys and girls. The homogeneity of odd ratios was tested with the Breslow-Day statistic using SPSS for Windows. RESULTS: For boys and girls, use of Internet chat rooms was associated with psychological distress, a difficult living environment, and a higher likelihood of risky behaviors. Although most chat room users did not report serious problems, this group included a disproportionate number of troubled individuals. CONCLUSIONS: Because chat room use serves as an indicator of heightened vulnerability and risk-taking, parents and others need to be aware of potential dangers posed by online contact between strangers and youth.     

Detection of Human T-Lymphotropic Virus (HTLV) tax Sequences in New York City Blood Donors Seronegative for HTLV Types 1 and 2

A potential public health concern is the reported detection of the human T-lymphotropic virus (HTLV) tax gene in the lymphocytes of up to 11% of a low-risk group of New York City blood donors (NYBD). This study aimed to independently confirm the prevalence of HTLV tax sequences in 293 NYBD. All NYBD tested negative for antibodies to HTLV types 1 and 2 and HTLV Tax. HTLV tax sequences were not detected in the NYBD lymphocytes. These data demonstrate the lack of HTLV-1 tax in this group of NYBD at low risk for HTLV infection.
