  • Incidence of asthma in female Swedish hairdressers.
  • 2002
  • In: Occupational and Environmental Medicine. - : BMJ. - 1470-7926 .- 1351-0711. ; 59:2
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: To investigate the risk of asthma in hairdressers. METHODS: The incidence of asthma was retrospectively estimated in a Swedish nationwide study including all female hairdressers certified from vocational schools from 1970 to 1995, and a stratified sample of women from the general population were referents. A postal questionnaire included questions on respiratory tract symptoms, atopy, smoking, working periods as a hairdresser, and number of specific hair treatments performed/week. Reported exposures were validated by occupational hygienists. Rate ratios of incidence (IRRs) of asthma were estimated by Poisson regression, adjusted for calendar year of observation, hay fever, smoking, and region of domicile. RESULTS: The crude incidences of asthma/1000 person-years were: 3.9 during active years as a hairdresser, 2.8 among the hairdressers when not working in the profession, and 3.1 among the referents. The corresponding IRR for being an active hairdresser compared with the referents was 1.3 (95% confidence interval (95% CI) 1.0 to 1.6). Moderate effects on risk of asthma were found both from hairdressing work (IRR=1.6 (1.1 to 2.2) among never-smokers) and from smoking (IRR=1.6 (1.2 to 2.2) among referents). However, the combined effect from hairdressing work and smoking (IRR=1.5 (1.0 to 2.1)) was less than expected (p=0.02). No effect modification by respiratory atopy was found. The hairdressers most often performing hair bleaching treatments (IRR=1.5 (0.7 to 3.0)) or using hair spray (IRR=1.4 (0.8 to 2.4)) had, compared with the most infrequent users, a slightly, but not significantly higher incidence of asthma. Exposure to persulphates in hair bleach was estimated to be 0.04-0.15 mg/m(3) during mixing of the powder. Reported average number of bleaching treatments agreed well with those performed according to a diary. CONCLUSIONS: Active hairdressing work was associated with a moderately increased incidence of asthma among lifelong non-smokers. The results are moderately supportive, but not conclusive, of associations between asthma and exposure to hair bleach or hair spray.

  • The incidence of respiratory symptoms in female Swedish hairdressers
  • 2003
  • In: American Journal of Industrial Medicine. - : Wiley. - 0271-3586. ; 44:6
  • Journal article (peer-reviewed)abstract
    • Background Airway diseases in hairdressers are a concern. The objective of this investigation is to evaluate the risk for three respiratory symptoms, wheeze, dry cough, and nasal blockage, in hairdressers. Methods A questionnaire on respiratory symptoms, atopy, smoking, and work history was answered by 3,957 female hairdressers and 4,905 women from the general population as referents. Incidence rates (IR) and incidence rate ratios (IRRs)for the three symptoms were estimated. Results The IRs of all three studied symptoms were higher in the hairdressers compared with the referents. Smoking modified the effects of cohort affiliationfor all threesymptoms; the combined effect from hairdressing work and smoking was less than expected. In addition, the effect of cohort affiliation for wheeze was also modified by atopy, and the effect of cohort affiliation for nasal blockage was also modified by calendar year. Conclusions Hairdressing work was associated with increased incidences of respiratory symptoms. Smoking had a negative modifying effect.

  • Incidence of hand eczema in female Swedish hairdressers
  • 2007
  • In: Occup Environ Med. - : BMJ. - 1470-7926 .- 1351-0711. ; 64:3, s. 191-5
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: To estimate the occurrence of hand eczema in hairdressers in Sweden. METHODS: The occurrence of hand eczema was estimated in a Swedish longitudinal retrospective cohort study including all female graduates from vocational schools for hairdressers from 1970 to 1995. A stratified sample from the general population acted as controls. A self-administered questionnaire including questions on the occurrence of hand eczema, skin atopy, working periods and number of hair treatments performed per week was sent to the participants. Incidence rate ratios (IRRs) of hand eczema were estimated. RESULTS: The incidence rate of hand eczema in hairdressers was 23.8 cases/1000 person-years, whereas in hairdressers who were aged <25 years it was 37.1/1000 person-years. The corresponding IRR for hairdressers compared with controls was 2.5 (95% confidence interval (CI) 2.2 to 2.8), and that for younger hairdressers was 3.1 (95% CI 2.6 to 3.5). The mean age at onset of hand eczema was 21.6 years for hairdressers and 21.2 years for controls. The 1-year prevalence of hand eczema was 18.0% for hairdressers and 12.1% for controls. A large number of hair treatments involving exposure to skin irritants and sensitisers were reported. The incidence rate of hand eczema was higher among individuals with a history of childhood eczema, both for hairdressers and for controls, giving an (age-adjusted) IRR of 1.9 and 2.2, respectively. The attributable fraction of hand eczema from skin atopy was 9.6%. A synergistic effect of skin atopy and hairdressing was found on the occurrence of hand eczema. The relative excess risk due to interaction was 1.21 (95% CI 0.21 to 2.21; p = 0.01). CONCLUSION: Hairdressers are highly exposed to skin-damaging substances. The self-reported incidence of hand eczema was substantially higher in female hairdressers than in controls from the general population and than that found previously in register-based studies. For many individuals, onset of hand eczema occurs early in life. Only about 10% of the hand eczema cases among hairdressers would be prevented if no one with skin atopy entered the trade.

  • Survival time in a population-based consecutive series of adult acute myeloid leukemia--the prognostic impact of karyotype during the time period 1976-1993
  • 2000
  • In: Leukemia. - 1476-5551. ; 14:6, s. 1039-1043
  • Journal article (peer-reviewed)abstract
    • A consecutive population-based series of 372 adult acute myeloid leukemias, successfully cytogenetically investigated at a single center between 1976 and 1993, is reported. All medical records were reviewed in order to ascertain the prognostic impact of karyotype, divided into three groups; favorable (t(8;21), t(15;17), and inv(16) irrespective of karyotypic complexity; n = 40), poor (der(1;7), inv(3), -5, del(5q), -7, t(9;22), and complex karyotypes including whole or partial losses of chromosomes 5 and/or 7; n = 56), and intermediate (other abnormalities or normal karyotype; n = 276). The possible modification by age, gender, time period, morphologic subtype, and bone marrow transplantation (BMT) on this prognostic impact was also determined. The chemotherapy regimens used were heterogeneous over time but principally the same at any given point in time. The majority of the patients were treated with combinations including an anthracycline and cytarabine with curative intent. Gender, morphology, and BMT did not significantly modify the effect of cytogenetic patterns on survival time, whereas age and time period did. The hazard ratios for the subgroups favorable, intermediate, and poor were 1.0, 1.2 and 1.9 at age 20-49; 1.0, 2.5 and 4.5 at age 50-64; 1.0, 4.1 and 11.4 at age 65-74; 1.0, 1.4 and 2.2 for the time period 1976-1987 and 1.0, 2.0 and 6.7 for 1988-1993. The salient feature of the Kaplan-Meier curves was the improved survival during the later time period for patients with favorable and intermediate cytogenetic abnormalities. The present findings thus suggest that it is mainly these patient groups that have benefited from advances in therapy, including supportive care.

  • The prognostic impact of karyotypic subgroups in myelodysplastic syndromes is strongly modified by sex
  • 2001
  • In: British Journal of Haematology. - : Wiley. - 0007-1048. ; 113:2, s. 347-356
  • Journal article (peer-reviewed)abstract
    • The prognostic impact of karyotypic patterns in a consecutive series of 389 adult myelodysplastic syndromes (MDS) was investigated. Time period did not significantly influence the survival times. In the analyses, the MDS cases were subdivided into the cytogenetic subgroups used in the International Prognostic Scoring System, i.e. favourable [-Y, del(5q) or del(20q) as single aberrations or normal karyotype, n = 241], poor [-7, del(7q), der(1;7) or complex karyotypes, i.e. > or = three abnormalities, n = 89] and intermediate (other aberrations, n = 59). The survival times correlated well with the prognostic subgroups, confirming that the cytogenetic classification was valid. Expressed as hazard ratios (HRs), with the favourable subgroup as the reference, the intermediate and poor subgroup HRs increased to 1.5 (95% confidence interval, 1.1-2.1) and 3.2 (2.4-4.1) respectively. Sex, age, morphological subtype and smoking habits significantly modified this prognostic impact. Shorter survival was detected for men in the favourable and the intermediate subgroups, but not in the poor prognosis subgroup. Using women in the favourable subgroup as the reference and adjusting for age, the HR for men was 1.6 (1.2-2.1) in the favourable subgroup. Adjusting for smoking habits as well decreased the HR to 1.4 (1.1-2.0) and, when also excluding cases with del(5q) as the sole anomaly, no significant difference could be discerned [HR 1.2 (0.9-1.6], suggesting that the better outcome for women in the favourable subgroup was mainly as a result of the '5q-syndrome' and to smoking habits. In the intermediate subgroup, the corresponding HRs were 3.0 (1.5-6.0) when adjusted for age and 2.7 (1.3-5.5) when also adjusted for smoking habits. Different survival times between men and women have never previously been reported for this MDS group. Although it remains to be elucidated whether environmental and/or constitutional factors cause the observed sex-related difference, these observations have obvious clinical ramifications, not least in designing and evaluating therapy protocols.

  • Mortality and cancer incidence in cohorts of Swedish fishermen and fishermen's wives: Updated findings.
  • 2009
  • In: Chemosphere. - : Elsevier BV. - 1879-1298 .- 0045-6535. ; 74, s. 938-943
  • Journal article (peer-reviewed)abstract
    • OBJECTIVES: Intake of fish is an important source for many essential substances, such as n-3 PUFA. However, certain fish also contains relatively high levels of PCBs and dioxins. In Sweden, the concentrations of these compounds are higher in fatty fish caught at the east coast as compared to fish from the west coast. The aim of the present study was to assess cancer incidence and mortality pattern among cohorts with a relatively high intake of locally caught fish from the Swedish coasts. METHODS: Cohorts of fishermen and fishermen's wives from the Swedish west and east coasts were established. Cancer incidence and mortality patterns were assessed up to year 2002, and cause-specific standardised incidence (SIRs) and mortality (SMRs) ratios were calculated. RESULTS: Low rates for overall mortality were observed in the two cohorts from the west coast. We observed lower than expected rates especially for respiratory and cardiovascular diseases. Incidence of colon cancer was lower than expected among the east coast fishermen and higher than expected among the east coast wives. Consistently increased incidence of lip cancer, and an elevation of the squamous cell skin cancer incidence, was seen in the fishermen cohorts. CONCLUSIONS: The low rates for overall mortality and cancer incidence, and low death rates for major diseases, and the low colon cancer incidence, indicates a positive impact of high dietary fish consumption, and health benefits from a highly physically active work environment for the fishermen. Sun exposure as an occupational hazard among fishermen should not be neglected.
