Public health interventions to encourage TB class A/B1/B2 immigrants to present for TB screening.

From 1985 to 1995 the proportion of all Santa Clara County, California (SCC), tuberculosis (TB) cases among recent immigrants climbed 73% (137 to 237). In SCC the efficient and cost-effective means encouraging TB Class A/B1/B2 immigrants (TBIMs) to present for TB screening and the prevalence of active TB among them were never investigated. We studied all TBIMs entering SCC from October 1, 1995 to June 30, 1996, notified to SCC by the CDC's Division of Quarantine (DQ).

A double blind, randomised, parallel group study to investigate the dose equivalence of Dysport and Botox in the treatment of cervical dystonia.

Objective: This study was designed to establish whether a ratio of three units of Dysport is equivalent to one unit of Botox for the treatment of cervical dystonia.

Methods: Patients with predominantly rotational cervical dystonia, and a minimum of four previous Botox treatments, were randomised to receive either the clinically indicated dose of Botox or three times that dose in Dysport units. Study botulinum toxin was administered in a double blind fashion, to one or more clinically indicated muscles, at one or more sites per muscle.
