To the Editor: Fox et al. used computer-assisted telephone interview (CATI) techniques in an outbreak of cryptosporidiosis (1). Australian health agencies have used CATI for several years. A case-control study during an outbreak of Salmonella Mbandaka in 1996 employed CATI to interview 15 casepatients and 45 controls; contaminated peanut butter was implicated (2). Foodborne disease outbreaks ar...

BACKGROUND Neuroinvasive larvae of the worldwide occurring zoonotic roundworms Toxocara canis and T. cati may induce neurotoxocarosis (NT) in humans, provoking a variety of symptoms including cognitive deficits as well as neurological dysfunctions. An association with neuropsychological disorders has been discussed. Similar symptoms have been described in T. canis-infected mice, whereas data on...

BACKGROUND Many epidemiological and public health surveys report increasing difficulty obtaining high participation rates. We conducted a pilot follow-up study to determine whether a mailed or telephone survey would better facilitate data collection in a subset of respondents to an earlier telephone survey conducted as part of the National Birth Defects Prevention Study. METHODS We randomly a...

background: the effect of temperature and humidity on the maturation of toxocara cati eggs in an in vitro system was investigated. methods: suspensions of toxocara cati eggs, with 5% formalin/saline or 2.5% formalin/ringer were prepared and maintained at 37 °c under 40% humidity or at 25 °c under 98% humidity for 3 weeks for egg development. results: the suspension sample mixed by 2.5% formalin...

BACKGROUND Education campaigns seeking to raise awareness of human papillomavirus (HPV) and promoting HPV vaccination depend on accurate surveys of public awareness and knowledge of HPV and related sexual behavior. However, the most recent population-based studies have relied largely on computer-assisted telephone interviews (CATI) as opposed to face to face interviews (FTFI). It is currently u...

Last year we present the new FNRS project, CATI (Charging and accounting Technology for the Internet). This new paper gives the state of progress of CATI. In this paper we focus our attention on a few points mentioned above, namely: • we describe briefly the final CATI architecture interfacing IntServ and DiffServ technologies; • we particularly focus on the topic concerning the charging and th...

Ilinkaccenturam No.1, Canta Cantirotayam, Kowri Cintamani Centuram and Cati Campirakkulampu the four mercurial drugs of Siddha system of medicine have been chemically analysed for laying down standards. The physico-chemicals data presented can be taken as parameters to fix standards.

We report four cases of passage of subadult or adult Toxocara cati worms by young children ages 20 months to seven years. Worms were expelled rectally in two cases and in two cases they were vomited. A single worm was passed in two cases, three worms in one case, and 15 worms in the fourth case. All worms that were available for study were identified as T. cati by morphologic criteria, includin...

Statistics Belgium set up an outbound call centre for the collection of output prices by way of computer-assisted telephone interviewing; the software used is the CATI-module of Blaise. Telephone interviewing was chosen because it allows very rapid data collection, which is crucial for output prices information. Another limiting factor for data availability, however, is the time and effort spen...

BACKGROUND Little is known about the impact of data collection method on self-reported cancer screening behaviours, particularly among hard-to-reach populations. The purpose of this study is to examine the effects of data collection mode on response to indicators of cancer screenings by unmarried middle-aged and older women. METHODS Three survey methods were evaluated for collecting data abou...
