Objective: In Miyagi, the number of allergy specialists per population is higher at Sendai city compared to the other areas (non-Sendai areas). Therefore, the healthcare delivery for allergic diseases are unevenly distributed. In the current study, we investigated differences of medical care for allergic diseases between Sendai city and non-Sendai areas.

Methods: We conducted a web-based questionnaire survey to all of hospitals and clinics in the prefecture. The questionnaire responses were analyzed and compared between the Sendai city and non-Sendai areas.

Results: Responses to the questionnaire were obtained from 175 hospitals and clinics, including 72 internal physicians, 34 pediatricians, 17 dermatologists, 15 otorhinolaryngologists, 12 ophthalmologists and 25 others. More clinicians in non-Sendai areas felt the difficulty in treating asthma and chronic urticaria than those in Sendai city. Fewer institutions prescribed biologics for severe allergic diseases in non-Sendai areas than in Sendai city, which might be due to the lack of knowledge on the biologic agents. On the other hand, referring patients with anaphylaxis to specialized hospitals tended to be more difficult in Sendai city compared to in non-Sendai areas. Additionally, the regional medical liaison system is needed to refer patients with severe allergic diseases to advanced medical institutions.

Conclusion: There are unique problems about allergy care in Miyagi.

Objective: To clarify the frequency of imaging findings similar to mycobacterial infection and the characteristics of comorbid pulmonary non-tuberculosis mycobacteriosis in the patients with allergic bronchopulmonary mycosis (ABPM).

Subjects and Methods: Patients treated with ABPM at our hospital in the past 8 years were extracted from medical records, and 32 patients who met the clinical diagnostic criteria were retrospectively examined.

Results: The median age was 62.5 years (range 24-79 years), and 21 patients were female. Twenty-two had asthma, and four had old tuberculosis. CT findings showed central bronchiectasis in 29 cases, centrilobular nodulars in 26 cases, and mediastinal lymphadenopathy in 3 cases. Pulmonary M. avium complex (pMAC) disease was complicated in 4 cases. Regarding the time of diagnosis of pMAC disease, 2 cases were diagnosed concurrently with ABPM, 1 case was before ABPM diagnosis, and 1 case was during ABPM treatment. The main lesion of ABPM occurred in a different site from that of pMAC disease.

Conclusions: ABPM and mycobacterial infection not only have similar imaging findings, but they can also occur synchronously and metachronously. Complication of ABPM and pMAC disease may be due to risk factors common to both diseases, such as the patient's constitution and living environment.

Background: Inducible laryngeal obstruction (ILO) refers to respiratory disorders caused by airflow limitation in the larynx, including vocal cord dysfunction, and may sometimes be misdiagnosed as bronchial asthma (BA). Here, we report the case of an 11-year-old boy diagnosed with BA in infancy. He was referred to our Allergy Center and was taking a high dose of inhaled corticosteroids (ICS) due to frequent coughing from the age of 10 years and persistent coughing following COVID-19 infection at the age of 11. However, the patient continued to experience frequent coughing attacks and repeated visits to the emergency department after inhalation of β₂-stimulants failed to improve his cough. We admitted him to the allergy center for examinations to assess the BA severity. In the airway hypersensitiveness test, saline inhalation performed prior to methacholine inhalation caused expiratory stridor and respiratory distress in the larynx, which worsened with β₂-stimulant inhalation. Based on these results, we ruled out BA and diagnosed ILO. We instructed him on breathing maneuvers, and he was able to respond appropriately when symptoms appeared. We then started reducing his ICS dose.
