ABSTRACT: Significant advances have been noticed in the pathogenesis and the diagnosis of extrinsic allergic alveolitis during the last few years. Indeed the immune mechanism and the enabling conditions have been more precisely defined, the clinical stages and the diagnosis criterias clearly defined, new antigens incriminated and some etiological agents have been reclassified. The present pathogenic explanation insists on the type IV hypersensitivity reaction with sensitization of T lymphocytes, activation macrophages, the formation of IgG type antibodies and immune complexes, activation of complement and secretion of cytokines. The involvement of certain HLA classes (HLA2, DR3, DRB1, DQB1), interaction of genetics and environments factors, the role of infections agents and smoking have been demonstrated in several studies. The development of news clinical and biological diagnosis criteria have led the discovery of new extrinsic allergic alveolitis in the work places, a better knowledge of the prognostic elements and an appropriate adaptation of prevention measures.

ABSTRACT: The medical deontology regroups duties of the physicians and regulate the exercise of medicine. The code of medical deontology of Senegal inspired of the French medical deontology code, has not been revised since its institution whereas the French deontology code knew three revisions. Comparing the two codes of deontology titles by title and article by article, this work beyond a parallel between the two codes puts in inscription the progress in bioethics that are to the basis of the revisions of the French medical deontology code. This article will permit an advocacy of the health professionals, in favor of a setting to level of the of Senegalese medical deontology code. Because legal litigation, that is important in the developed countries, intensify in our developing countries. It is inherent to the technological progress and to the awareness of the patients of their rights.

ABSTRACT: The aims of this study were to appreciate how frequent asthma was named in the legal list of worker's compensation, state hazards and occupations involved and appreciate conditions required for a legal recognition of the disease. The study consisted of a review of the legal list of occupational diseases of all tables where asthma was stated. Medical, technical and administrative criteria allowing compensation were looked for. Asthma was listed in 12 among the 67 tables; causal substances listed were known as sensitizers and included mainly organic and metallic compounds. Numerous occupations were concerned in all primary, secondary and tertiary sectors. Medical conditions refered to "all asthma confirmed by functionally respiratory tests or regenerated by a new exposure". Time length of declaration was seven days. Variety of occupations concerned and numerous substances involved should invite to look for occupations in all patients with asthma. Physicians should be aware of theses legal conditions in order to recognize better occupational asthma and ease it legal compensation.

ABSTRACT: This study was conducted from may to august 2000 in three senegalese work sites randomly selected among seven which benefited from HIV preventive program. The aims were to evaluate knowledge, attitude and behavior related to HIV infection. A sample of 200 workers randomly chosen were asked about the ways of transmission and methods of protection as well as their risky attitudes and behaviors. Mean age was 41 years, 82.5% were male and 75.5% benefited from high school education; 75.75% had a good level of knowledge on HIV infection, 58% CI [51-65] stated having changed their sexual behavior into abstinence, fidelity to their partner (52.5%) and use of condom (46.5%). This good level of Knowledge and the positive changes in attitude are related to the high rate of alphabetization in our sample, information message diffused by media and preventive programs undertaken in workplace. Information campaigns via media should be maintained and strengthened and preventive programs diffused in all workplaces which will reduce diffusion of HIV in population.

ABSTRACT: We report an hydrogen sulfite intoxication which occurred in a Senegalese chemical plant and which lead to the death of three temporary workers in charge of cleaning up the pumping basin of seawater. Hydogen sulfite was generated by the decomposition of seaweeds and other inorganic compounds. Agitation of water due to human presence increased the air concentration at very high levels. The death of workers trying to rescue their colleagues was due to their ignorance of key elementary prevention rules. Diagnosis was based upon microbiologic analysis and air sampling. The ignorance of toxicologic effects of this widespread substance invite to inform people working in industries where the risk of hydrogen sulfite intoxication is high.

ABSTRACT: A variety of occupational asthma is induced by important exposure to irritants. A case is reported, where le patient developed asthma symptoms like, following huge exposure to sulfur dioxide. All Books criteria were met, except for the metachlorine challenge which was not performed. Nevertheless the bronchial reactivity in the work place, shown by a portable pick flow eased le diagnosis. General practitioners and occupational physicians should be aware of this new medical entity for a better management.
