    Notes: A study was made of the protective action of the anti-allergic drug ICI 74,917, a phenanthroline derivative, in specific allergen provocation tests and in combating clinical symptoms in thirteen asthmatic out-patients. It was found that ICI 74,917 was able to diminish allergen-induced bronchoconstriction significantly (P〈 0.01) during both the placebo period and during chronic treatment with ICI 74,917 for 4 weeks. The results obtained during these two periods did not differ significantly. There was not, however, any statistically significant difference in the symptom scores or PEF rates during the treatment with ICI 74,917 or placebo for 1 month. This may indicate that although ICI 74,197 is able to prevent bronchoconstriction in an allergen provocation test, it failed to improve asthma clinically. No signs of the phenomenon of tachyphylaxis were observed in the present study.The Student's t-test was used in the statistical analysis.

    Notes: In an industrial community, Linnavuori, (population 1000) over 100 people developed fever, cough, and dyspnoea 3 to 6 hours after sauna or bathing. This epidemic began in August of 1978 and ended gradually in December. The water source of the community was a small (0.4 km2) lake; in November it was found that the water was contaminated with several bacteria, fungi, and algae. Precipitating antibodies to these bacterial and fungal antigens were not found in the sera of symptomatic patients. To show that tap water, purified by the local waterworks, had provoked the symptoms, four clinically typical patients were each twice challenged. Two of the patients visited their usual public sauna, the two others took a bath at home. Two patients inhaled home tap water aerosol, one inhaled lake water vapor and one home tap water vapor in hospital. Three to six hours after seven of the eight challenges the patients showed two or more of the following symptoms and signs: chills, fever, dry cough, dyspnoea, and inspiratory crepitant râles. Six provocations increased the amount of segmented neutrophils and in each case the lung diffusion capacity decreased significantly. Although the clinical picture resembles extrinsic allergic alveolitis, it is possible that bacterial endotoxins have induced alternative pathway complement activation and release of leukocyte pyrogens.A respiratory syndrome much resembling exogenous allergic alveolitis, and caused by micro-organism-contaminated water from air humidifiers and ventilation systems, has become more commonly diagnosed in the 1970's. This disease is also called hypersensitivity pneumonitis or humidifier fever. Banaszak, Thiede & Fink (1970) described four office clerks whose symptoms were shown to be caused by contamination of the office ventilation system by a thermophilic actinomycete. Inhalation tests with the homologous antigen provoked similar symptoms. Fink et al. (1971) found

    Clinical symptoms and immunologic reactivity to bee and wasp stings in beekeepers (1995)

    Notes: We compared the history of sting reactions with venom skin prick test (SPT) and CAP RAST reactions in beekeepers in order to assess the value of structured questions and symptom backgrounds. The study population consisted of 102 beekeepers, who were 25–75 years of age. Bee and wasp venom SPT was performed with concentrations of 10, 100, and 300 μg/ml. The CAP Phadiatop® test was used in the screening of IgE antibodies against common inhalant allergens. Eorty-two beekeepers had never experienced large local or systemic reactions after a bee sting. Of the 31 subjects with a history of systemic reactions, 13 had experienced these during the previous year. A significant difference (P〈0.01) between systemic reactors and nonreactors was found in bee venom CAP and SPT (300 μg/ml). However, due to considerable overlap, these tests are unable to discriminate between allergic and nonallergic beekeepers. Both bee venom SPT (300 μg/ml) and CAP tests were positive in 65% of systemic reactors and in 34% of nonreactors (P=0.008). Venom SPT (300 μg/ml) correlated significantly with CAP for both venoms. No correlation was observed between venom allergy and atopy. Clinically, the most practical concentration for evaluating bee and wasp venom sensitization by SPT proved to be 300 μg/ml.

    Comparison of immunologic tests in the diagnosis of occupational asthma and rhinitis (1994)

    Notes: In this study, three immunologic tests, skin prick test, RAST, and basophil histamine-release test (BHRT), were compared by provocation in the diagnosis of occupational asthma and rhinitis. Twenty-three positive bronchial or nasal challenges were performed on 16 patients (six farmers, six bakery workers, and four food industry workers) and asthma or rhinitis was diagnosed as caused by cereal flour or grain, cow epithelium, storage mites, garlic, or soy dust. A control group consisted of 12 patients, of whom four (two bakery workers, one food industry worker, and one farmer) were challenge-negative, and the rest suffered from pollen allergy and seasonal rhinitis and were not challenged. The sensitivity and specificity of the prick test, RAST, BHRT, and a panel of them were as follows: 74 and 89%, 57 and 86%, 78 and 93%, and 91 and 71%, respectively. The overall concordance among these three type I allergy tests or between immunologic tests and challenge was relatively good.

    Notes: The oral health status and stimulated salivary flow rate of 33 adult asthmatic outpatients were compared with those of 33 nonasthmatic controls. The groups were matched by age and sex, and an adjustment for education was made in the statistical analysis. In the oral examination, a small difference in the prevalence of caries was observed when the sums of decayed, missing, and filled teeth (DMPT) were compared. The mean (SD) crude DMFT score was 20.1 (.5.8) in the asthma group and 18.4 (7.6) in the control group. A statistically significant difference was seen in the amount of periodontal inflammation and in the stimulated salivary flow rate between the groups. The mean (SD) crude periodontal status index (PSI) was 52.7% (23.8%) in the asthmatics and 37.1% (20.4%) in the controls. TTie 95% confidence interval (95% CI) for the difference in adjusted means of PSI ranged from 0.1% to 21.9% (P=0.05). In the stimulated salivary flow rate, crude mean values were 1.0 (0.5) ml/min and 1.3 (0.5) ml/min. respectively, and the 95% CI for the difference was from 0.05 ml/min to 0.57 ml/min (P=0.01). Mucosal lesions in the oral cavity were found in 15 asthmatics (45%) and in eight controls (24%). In conclusion, the results of this study support the hypothesis that adult asthmatics have a higher risk of oral diseases than nonasthmatic subjects.

    Notes: Summary The dose-response relationship of activated charcoal in reducing serum cholesterol was determined and the effects of charcoal and cholestyramine were compared in patients with hypercholesterolaemia. In a cross-over study 7 patients ingested charcoal 4, 8, 16 or 32 g/day, and finally bran, each phase lasting for 3 weeks. Serum total and LDL-cholesterol were decreased (maximum 29% and 41%, respectively) and the ratio of HDL/LDL-cholesterol was increased (maximum 121%) by charcoal in a dose dependent manner. Ten further patients with severe hypercholesterolaemia ingested daily for 3 weeks, in random order, activated charcoal 16 g, cholestyramine 16 g, activated charcoal 8 g + cholestyramine 8 g, or bran. The concentrations of total and LDL-cholesterol were reduced by charcoal (23% and 29%, respectively), cholestyramine (31% and 39%) and their combination (30% and 38%). The ratio of HDL/LDL-cholesterol was increased from 0.13 to 0.23 by charcoal, to 0.29 by cholestyramine, and to 0.25 by their combination. Serum triglycerides were increased by cholestyramine but not by charcoal. Other parameters, including the serum concentrations of vitamin A, E and 25(OH)D3 remained unaffected. The changes in lipids only partly subsided during the 3-week bran phase. In general, the acceptability by the patients and the efficacy of activated charcoal, cholestyramine and their combination were about equal, but there were individual preferences for particular treatments.
