The Living Tomorrow Project: how Philip Morris has used a Belgian tourist attraction to promote ventilation approaches to the control of second hand smoke.

STUDY OBJECTIVE: To examine the involvement of Philip Morris in Living Tomorrow 2 and determine the rationale behind its involvement. DESIGN: Research was conducted through a web based search of internal tobacco industry documents made publicly available through litigation. MAIN RESULTS: For approximately 1,000,000 euros Philip Morris (now Altria) became a co-initiator of Living Tomorrow 2, a tourist complex in Belgium that aims to demonstrate how we will be living in the future. In addition to promoting the company and its grocery products, Philip Morris is using the complex and its website to promote ventilation as a means of accommodating smokers and non-smokers in the indoor environment. Particular emphasis was placed on the bar and restaurant areas. Despite the rationale for its involvement, Philip Morris fails to acknowledge its role as a cigarette manufacturer. As a form of corporate sponsorship Philip Morris thought its involvement could evade any European tobacco advertising ban. CONCLUSIONS: Philip Morris is using a tourist attraction to promote its views on control of second hand smoke (SHS) and accommodation of smokers and non-smokers in the indoor environment. However, ventilation does not deal with the health effects of SHS. Policymakers must be cognisant of the devious tactics the industry employs to promote its own agenda, especially in relation to indoor air quality and smoking in public places. Tobacco control legislation should be continually modified and strengthened in response to the changing activities of the tobacco industry as it strives to evade existing legislation and deter the advent of new legislation.

Tuberculosis epidemiology in Croydon.

A survey of tuberculosis in Croydon between 1988 and 1991, using Chest Clinic health visitor records, showed that the disease occurred most frequently in those of Indian Sub-Continent (ISC) ethnic origin. Of the 222 cases during the 4-year period, 65% were of ISC ethnic origin, 22% were Caucasian and 11% Afro-Caribbean. Non-Caucasian cases were younger (P < 0.0001), and more likely to be female (P = 0.064) or present with non-pulmonary disease (P = 0.064). One-quarter of ISC patients developed active tuberculosis more than 15 years after immigration into the UK. Only seven cases were children. The contact tracing procedure resulted in three additional cases, all of whom were contacts of smear-positive index cases. There were significantly fewer Heaf or radiologically positive contacts of non-smear positive pulmonary, or non-pulmonary index cases (P = 0.0002). The value of the current contact tracing system is discussed.

Adenovirus-induced inclusion body hepatitis in four-day-old broiler breeders.

Two separate parent broiler flocks originating from the same grandparent flock experienced mortalities of 23% and 40%, respectively, in chicks between 1 and 14 days of age. Chicks affected at 4 days of age had tremors, depression, and hypoglycemia. They had pale yellow, swollen, friable livers. Pancreata were discolored and hemorrhagic. Spleens were swollen and sightly darkened. Microscopic lesions consisted of multifocal areas of acute hepatic and pancreatic necrosis with numerous basophilic intranuclear inclusions with karyomegaly. Splenic sections had severe lymphoid depletion and reticular cell and macrophage hyperplasia. An adenovirus from affected livers was isolated in chicken embryo liver cells. Serologic evidence suggests that the grandparent flock began egg production seronegative to adenovirus antibodies, was exposed during production, and, subsequently, shed adenovirus vertically to its progeny. The clinical syndrome was reproduced by injecting the isolated adenovirus into 1-day-old antibody-negative chicks. Histologic lesions in the experimentally reproduced disease cases were identical to those in the naturally occurring cases.
