    Background: A few previous studies have compared the patch test (PT) results obtained using different types of PT units.

    Objectives: This study aimed to compare PT results between the Patch Tester ‘Torii’ and Finn Chamber.

    Methods: Thirty-four patients with intractable scalp dermatitis were enrolled in this study. PT were performed with three kinds of amphoteric surfactants, cocamidopropyl betaine (CAPB), high-concentration CAPB (h-CAPB), and lauramidopropyl betaine (LAPB), using both the Patch Tester ‘Torii’ and Finn Chamber, and the changes in the subjects' symptoms after they stopped using these surfactants were examined.

    Results: Regarding the PT results for CAPB, h-CAPB, and LAPB, the results obtained with the Finn Chamber included a significantly lower frequency of irritant reactions (CAPB; p=0.003, h-CAPB; p=0.046, LAPB; p=0.002) than those obtained with the Patch Tester ‘Torii’. However, there were no significant differences in the frequencies of positive reactions between the Patch Tester ‘Torii’ and Finn Chamber in each surfactant. The same tendency was seen in PT with LAPB (p=0.041) in 17 selected patients, who showed positive or doubtful reactions in PT performed with the surfactant-containing products they had used and whose symptoms ‘markedly improved’ or ‘improved’ after they stopped using these products. Among these surfactants, CAPB exhibited the highest positivity rate; however, the differences were not significant.

    Conclusion: In patients with intractable scalp dermatitis, PT of the abovementioned surfactants performed using the Finn Chamber were superior to those conducted using the Patch Tester ‘Torii’ because they resulted in fewer irritant reactions.

    Patient 1 was a female patient in her teens who presented with swelling of the lips and oral discomfort after consuming mung bean sprouts. She had a history of this reaction since the age of 6 years and showed positive on a prick-to-prick test for mung bean sprouts. Patient 2 was a male patient in his twenties who also showed positive for mung bean sprouts as well as soybean sprout. Both patients were positive for IgE specific to birch, Gly m4, and Bet v1.

    Mung beans belong to the PR-10 family because they contain the allergenic component, Vig r1. A cross reaction to mung bean may occur in a patient with birch allergy as in the present cases. Mung bean sprouts are a cheap and common dietary item in Japan where, however, only a few cases of mung bean sprouts allergy have been reported. Mung bean sprouts allergy should be diagnosed with appropriate testing; if the patient has allergic reactions for this food item, an allergologist should provide detailed dietary guidance for avoiding pollen-food allergy syndrome.

    A 69-year-old woman presented with a persistent cough and high fever. Thoracic computed tomography revealed atelectasis and high-attenuation mucus. The blood test results showed eosinophils at 18.2%, an absolute eosinophil count of 980 cells/μL, and a total serum immunoglobulin E of 1980IU/mL. Bronchoscopy revealed a mucous plug, which upon photomicrograph examination, showed eosinophils. A culture study of the mucus yielded Scedosporium apiospermum, leading to the suspicion of allergic bronchopulmonary mycosis (ABPM) caused by the fungus. After the bronchoscopic removal of the mucous plug, her symptoms quickly diminished. She was successfully treated without medication, and ABPM has not recurred for 2 years. To our knowledge, ABPM caused by Scedosporium apiospermum is rare, and close follow-up was effective without the administration of systemic steroids or antifungal drugs.
