[Respiratory allergies among bakers and pastry cooks: epidemiologic survey done in 1991 by the occupational physicians of the Loire-Atlantique].

The aim was to study the prevalence of respiratory allergy (rhinitis and asthma) in a population of bakers and pastrycooks. In 1991, 485 bakers and pastry cooks were examined by 27 work-physicians of Loire-Atlantic. The investigation was composed of a standardised questionnaire (signs of respiratory function, atopic history, smoking of tobacco ...), a clinical examination, and tests of respiratory function. An allergy assessment was made of all subjects with symptoms. 14.4% of subjects had rhinitis and 6.4% asthma. Development of these pathologies was clearly job-related for 2/3 of those with rhinitis and more than half of the asthmatics (55%). Occupational rhinitis and asthma were significantly more frequent in bakers than in pastrycooks and were linked to atopic history. Occupational asthma was associated with length of exposure to flour and with occupational rhinitis. In conclusion, these findings are comparable with or a little less than those that have been reported in occupational literature. They under-estimate the importance of the problem because of the occupational selection effect that is associated with these pathologies. Rhinitis and asthma are 1.5 to 3 time more common in bakers than in pastrycooks.

[Respiratory allergies among symptomatic bakers and pastry cooks: initial results of a prevalence study].

A survey was carried out on respiratory symptoms and skin prick response to common allergens, storage mite and occupational allergens. Among 178 symptomatics bakers and pastry workers from small businesses in western France, only 65 people underwent skin prick and specific-IgE. 12 (18%) workers were skin positive to at least one common or occupational allergens. The more often skin positive were D. Ptero. mite 36 (57%); Alpha amylase 23 (35%); wheat flour 17 (26%); saccharomyces cerevisiae 16 (25%); Ephestia 15 (24%). The sensitivity of skin test was better than specific IgE for D. Ptero. Mite 36 (57%); and Alpha amylase 23 (35%). The sensitivity of specific IgE was better than skin test for wheat flour 26 (45%) and rye flour 23 (40%). Occurrence of skin positive to occupational allergen among symptomatics with rhinitis and asthma is much more frequent in workers with skin positive to common allergens (40/36) than in workers with skin negative (8/20). Atopy must be regarded as an important predisposing factor for skin sensitisation to occupational allergens. We conclude in the necessity of a standardised allergologic exploration to be done in symptomatics bakers.

Streptococcus suis meningitis. A severe noncompensated occupational disease.

Meningitis caused by Streptococcus suis type 2, a rare disease first recognized in 1968 (108 cases worldwide in 1989), is contracted by occupational exposure to pigs and often results in very severe disabilities (definitive deafness and ataxia in 50% of cases). We report the case of an employee in a rendering plant whose initial symptom was deafness. A detailed analysis of medical and veterinary literature is provided concerning the epidemiology of the disease, the clinical forms in man, bacteriological diagnosis and the role of the pig as healthy carrier. It is recommended that this occupational disease be officially recognized for compensation in France.

Animals

[Household cleansers and nickel allergies].

Attention of authors has been drawn by the observation of patients presenting a nickel-dermatosis, instigating by the touch of jewelry (ear-rings, bracelets, necklaces...) and also a sensitization for housework cleansing agents. The chemical analysis of numerous housework cleansing agents exhibited the constant presence of nickel in these housework cleansings. These investigations enable the authors to affirm a close relationship between sensitization for nickel and sensitization for housework cleansings. Some patients present also sensitization for chromium or cobalt. The authors think this polysensitization is induced by metal's contamination.

[Suppurative trichophytosis of animal origin. Apropos of 38 recent cases].

This study of 38 cases observed over a period of 7 years emphasizes the constancy of rural contamination, whether professional or not. An enquiry carried out among veterinary surgeons in this region, showed the increasing frequency of the animal infection particularly in young oxen, hence the increased risk of kerions. The author recalls the clinical description of kerion of the scalp in children and sycosis barbae in adults, in which one may also encounter folliculitis of the limbs. The parasite isolated, included various strains of Trichophyton, e.g., Trichophyton Trimentagrophytes, Tr. verrucosum and, more rarely, Tr. magnini. On the other hand, bacteriological examination was usually negative, there were only two cases of secondary staphylococcal infection. The authors emphasize their concept of the disease which is probably an immune process. Finally, rather than the usual treatment, they emphasize the possibilities of social re-insertion; the disease should be recognised as an occupational disease.

[Epidemiology of S. aureus cross-infections in dermatological wards].

Over a three-year period, 196 of 3115 patients admitted in a dermatological department became infected with S. aureus (6,2 %). 205 strains of S. aureus were isolated. Serologic typing, phage-typing and antibiotic sensitivity tests revealed 3 epidemic and 2 endemic strains. The 3 epidemic strains infected 24 patients: 12 from july to november 1972 were infected with a serotype 66438 S. aureus resistant to fusidic acid. 6 patients (male) were infected with a serotype III in february and march 1972; 8 patients were contaminated with a serotype 18 S. aureus from december 1973 to february 1974, after staying in a surgical department. Of the 2 endemic strains 1, phage-pattern 53/79, is non-typable by serologic-typing; this strain has been observed only in the dermatological department and 20 patients were infected with, from january to october 1974. The second endemic strain, phage-pattern 81/+ serotype I, cross-infected 16 patients during this three-year survey; 12 of them were admitted repeatedly. During this three-year survey, it could be proved that, at least, 1 out of 3 patients is infected with an epidemic or an endemic strain. We can suggest that the factors enhancing cross-infection in dermatological department are: the sex of patients (80 % were male); presence of a tween splitting enzyme by S. aureus promotes growth of Staphylococci on the skin; patients transfered from a department to another or repeatedly admitted are more often infected. But, as they are source of some outbreaks, they need special measures (asepsis and hygiene); corticoïds or immunodepressors enhance cross-infection; antibiotics must not be only limited but varied too.
