“…The same study design and questionnaire formula were used in these two studies. Nevertheless, our ®gures for atopic dermatitis are comparable with some North European studies (11,13), but are 2 ± 3 times lower than those found in Finnish adolescents and conscripts (11,14), Swedish medical students (5), and adults in the south-west of Norway (6).…”

“…On the other hand, a prevalence 2 ± 3 times higher has been reported in schoolchildren in Scandinavia (1,3,4,15) and in Scotland (2) (9 ± 20% and 9 ± 20%, respectively). Furthermore, in recent North European studies levels of AR and urticaria are twice as high as those found in Nikel (4,6,11,14), however, our ®gures compare well with those from a Swedish study (16).…”

The cumulative incidence of atopic disease among adults was assessed in the heavily polluted Russian town Nikel on the Kola peninsula. The study was conducted in spring 1994 using a self-administered questionnaire. A total of 3,368 (93.6%) of the 3,600 subjects returned a completed questionnaire. Information about atopic diseases, smoking habits and living conditions in the family was also obtained. A cumulative incidence of atopic diseases of 11% was reported in 377 adults. This was significantly more frequent in women (12.7%) than in men (9.7%). Smoking habits differed from other western countries, as 53% of males and only 10% of females smoked. Indoor damp was reported by 13% and the keeping of dogs and cats by 52%. Our study indicates that atopic diseases is less frequent among adults in a heavily polluted Arctic Russian town than in western industrialized countries.

“…This finding did not change, when the definition of a positive skin test reaction was changed to a mean weal diameter of 3 mm, the cut-off point used in many studies [32][33][34][35]. Such frequent allergy to common alder has not previously been reported in Finland [33,36]. With the cutoff point of 3 mm, the prevalence of positive reactions to all allergens decreased by a mean of 6.6% (range from 2.0% for house dust mite to 14% for birch pollen).…”

“…In addition, in a study from England, 63% of wheezy children had at least one positive skin test reaction compared to 37% among children with dry cough [37]. In unselected populations, the prevalence is lower and usually varies between 17 and 39% [11,15,32,[34][35][36].…”

We also wondered whether chronic cough may be an indicator of occult asthma. Prevalence and characteristics of children with doctor-diagnosed asthma and chronic respiratory symptoms were investigated in 7-12 year old school children from eastern Finland by using a questionnaire on respiratory symptoms. In addition, skin-prick tests, flow-volume spirometry, and serum total immunoglobulin E (IgE) measurements were performed in children reporting chronic respiratory symptoms.The parent-reported prevalence of doctor-diagnosed asthma was 4.4%, of wheezing 5.4%, of attacks of shortness of breath with wheezing 4.6%, and of dry cough at night 12%. Children with dry cough only (n=195) had less frequent parental asthma, self-reported allergies, daily respiratory medication, and moisture stains or molds at home than asthmatic children (n=180), but these findings were more frequent than among asymptomatic children (n=2,169). The prevalence of at least one positive skin-prick test result was 79% among the asthmatic children and 55% among children with dry cough only. There were no differences between the two symptom groups in serum total IgE levels and spirometric lung functions, except in maximal mid-expiratory flow (MMEF) values, which were significantly lower among children with asthmatic symptoms.The present results support the hypothesis that chronic cough may be an indicator of occult asthma. Therefore, to improve the sensitivity of respiratory questionnaires designed to detect asthma, they should also include questions on chronic cough. In contrast to what has been suggested previously, the prevalence of childhood asthma in eastern Finland was similar to the prevalences reported from other parts of Finland and from other Western European countries.

“…It has proved the reproducibility of skin prick test results in a sensitive, precise and safe method, with fewer young men on two occasions separated by the non-specific reactions than intracutaneous or pollen season. However, few March and at the beginning of May (13). Testing for common allergens reveals the individual ability of the subjects to develop type I MATERIAL AND METHODS reactions-the atopic predisposition.…”

We studied the reproducibility of skin prick test reactions and tested 65 young men, picked from a population survey, in spring and fall. We used 16 extracts from two manufacturers with 12 common allergens. The extracts employed on both occasions were from the same allergen batches and the testing procedure was the same. Four subjects who reacted negatively in spring turned positive when re-tested in fall; the opposite happened to one subject. The result remained positive or negative on both occasions in 92%. The best reproducibility (96%) was obtained by pollens. The reactivity against tree and grass pollens was higher in fall than in spring; this is obviously a result of the immunologic stimuli induced by exposure to pollens during the season. The reactions caused by animal danders and house dust were, however, smaller in fall than in spring. This is believed to be due to young people being less exposed to indoor dust in summer. The immediate skin test reactivity is influenced by several factors; we would like to add one: the time of year when the test is applied. The reproducibility of skin prick test results is quite satifactory when the problem is approached as presented here.
