A composite three-dimensional echocardiographic technique for left ventricular volume estimation in children: comparison with angiography and established echographic methods.

A composite three-dimensional (3D) echographic left ventricular (LV) reconstruction to measure LV volumes was evaluated in 26 children. Four apical views, to minimize assumptions about LV shape, were used to obtain a "wire-cage" model of the LV in 3D. Numerical integration was used to make estimates of both end-diastolic and end-systolic volumes. Volume estimates obtained with echographic techniques and those obtained with the angiographic biplane method were compared. The echographic volume estimates were systematically smaller (p less than 0.005), and a consistent trend, though not significant, was observed indicating that this systematic error is less for the 3D method. One-way analysis of variance confirmed significant global geometric fluctuations. Hence, 3D reconstruction can be performed in a clinical setting, and the enhanced graphic representation of global LV geometry may contribute to improved patient management.

New approaches to addressing information needs in local public health agencies.

For local Public Health agencies to be fully responsive to community needs, staff must have ready access to up-to-date and accurate information. During the last several years, the Hamilton-Wentworth Department of Public Health Services (DPHS), a Teaching Health Unit affiliated with McMaster University, has been developing new information services including establishment of a specialized library on site; education sessions on the use of information stored in this library and in the Hamilton-Wentworth Health Library Network; innovative approaches to tailoring information services to staff needs including on-site access to on-line literature databases; and establishment of a group to retrieve and report community health data. In the initial three years of operation, surveys of Hamilton-Wentworth staff and a comparison health unit (Niagara) revealed that staff most frequently sought information from managers and support staff, as well as from personal books, articles and journals. Over half (57%) of the Hamilton-Wentworth staff reported use of the DPHS library, whereas 28% of Niagara Regional Health Unit staff reported use of their library. Other information services, for example, bibliographic indexes on population health, were less frequently used. Plans to increase their use are discussed.

Partner notification for sexually transmitted diseases: an overview of the evidence.

OBJECTIVE: To compare the effectiveness of alternative partner notification strategies for gonorrhea, chlamydia, syphilis, HIV and hepatitis B. DATA SOURCES: Studies were identified using MEDLINE, EMBASE, SCISEARCH and other databases, review of reference lists and personal contact with over 80 international experts. STUDY SELECTION: Studies with at least two comparison groups exposed to different partner notification strategies were included. DATA EXTRACTION: Methodological rigor was assessed, and information regarding study populations, interventions and outcomes was extracted independently by two reviewers. MAIN RESULTS: Twelve studies met our inclusion criteria; five were methodologically strong; seven provided data on the referral process; four provided data on trained interviewers compared with routine care providers; and three provided data on the interview process. CONCLUSIONS: Only limited, broad conclusions regarding the effectiveness of various partner notification approaches could be drawn from these comparative studies. Until newer data become available, practice guidelines must be based to a large extent on other grounds.
