A 60-year-old Japanese woman presented with subacute progressive muscle pain and weakness in her proximal extremities. She was diagnosed with influenza A (H3N2) infection a week before the onset of muscle pain. At the time of admission, she exhibited weakness in the proximal muscles of the upper and lower limbs, elevated serum liver enzymes and creatinine kinase, and myoglobinuria. She did not manifest renal failure and cardiac abnormalities, indicating myocarditis.Electromyography revealed myogenic changes, and magnetic resonance imaging of the upper limb showed abnormal signal intensities in the muscles, suggestive of myopathy. Muscle biopsy of the biceps revealed numerous necrotic regeneration fibers and mild inflammatory cell infiltration, suggesting immune-mediated necrotizing myopathy (IMNM). Necrotized muscle cells were positive for human influenza A (H3N2). Autoantibody analysis showed the presence of antibodies against the signal recognition particle (SRP), and the patient was diagnosed with anti-SRP-associated IMNM. She was resistant to intravenous methylprednisolone pulse therapy but recovered after administration of oral systemic corticosteroids and immunoglobulins. We speculate that the influenza A (H3N2)infection might have triggered her IMNM. Thus, IMNM should be considered as a differential diagnosis in patients with proximal muscle weakness that persists after viral infections., International Journal of Infectious Diseases, 103, pp.33-36: 2020

Background For asthma strategy, to avoid the aggravation of bronchial inflammation and contraction, the long acting beta agonist (LABA) addition on inhaled corticosteroids (ICS) has been recommended. Objectives To know whether there is any clinical difference between the additional efficacies of Formoterol (FOR) and Tulobuterol (TUL) onto Budesonide (BUD) may be useful for the elderly patients’ asthma treatment strategy. Methods Eighteen outpatients with mild to moderate bronchial asthma with FEV1.0% Results The “Fres” of IOS was improved in FBC group (p = 0.03). The “emotion” domain of mini-AQLQ was improved in BUD + TUL group (p = 0.03). Conclusion By changing the drug formulation, the patch was superior in terms of satisfaction, but it was thought that the inhaled combination was superior in improving the respiratory function itself. It is necessary to pay attention to the characteristics of the patient when selecting treatment.

Rationale, aims and objectives; For asthma strategy, to avoid the aggravation of bronchial inflammation and contraction, the addition of long acting beta agonist (LABA) to inhaled corticosteroids (ICS) has been recommended. To know whether there is any clinical difference between the additional efficacies of formoterol (FOR) and tulobuterol (TUL) onto budesonide (BUD) may be useful for the elderly patients’ asthma treatment strategy. Method: Eighteen outpatients with mild to moderate bronchial asthma with FEV1.0% < 80% treated by intermediate ICS dosages visited Respiratory Division of Nagasaki University Hospital or Isahaya General Hospital, Japan Community Health care Organization were subjected. Subjects were randomly assigned (9 cases per group) to either the FBC group (BUD/FOR 160/4.5 mcg: 2 inhalations twice daily) or BUD + TUL group (BUD 200 mcg: 2 inhalations twice daily + TUL 2mg daily) and were compared in parallel with 2 arms for 12 weeks prospectively. PEF, FEV1, impulse oscillometry (IOS), fractional exhaled nitric oxide, Asthma Control Questionnaire and mini-Asthma Quality of Life Questionnaire (mini-AQLQ), and occurrence of adverse reactions were compared. Results; The “Fres” of IOS was improved (p=0.03) in FBC group. The “emotion” domain of mini-AQLQ was improved (p=0.03) in BUD+TUL group. Conclusions; By changing the drug formulation, the patch was superior in terms of satisfaction, but it was thought that the inhaled combination was superior in improving the respiratory function itself. It is necessary to pay attention to the characteristics of the patient when selecting treatment.

In Nagasaki University Hospital, the patients undergoing surgery with abnormal respiratory function have been automatically referred to specialized clinic by Medical Support Center (MSC) since July 2016 to reduce surgery cancellations due to insufficient preoperative evaluation. Whether the MSC system decreased post-hospital surgery cancellation, variance rate, or length of hospital stays in patients received "lobectomy" were retrospectively compared between Period A (n = 264, before MSC introduction) and Period B (n = 264, after MSC introduction). Four patients' operations were cancelled after hospitalization in Period A, while 0 patients in Period B (p 0.05). The length of hospital stay, operation time, anesthesia time, and postoperative extubation oxygen administration time were all shorten in Period B significantly. "Period B", "operation time", and "postoperation oxygenation time" were independent factors for "hospital days", but chronic obstructive pulmonary disease or age were not. The preoperative intervention eliminated the operation cancellation. Preoperative MSC interventions may have contributed to the reduction in hospital days even for the patients with pulmonary dysfunction.

Anti-tumor necrosis factor alpha (TNFα) therapy is widely used to treat various inflammatory conditions. Paradoxically, there are several case reports describing the development of bronchocentric granulomatosis treated with TNFα inhibitors, and it is difficult to determine the effect of treatment using conventional spirometry because the lesions are located in small airways. However, it has been reported that the forced oscillation technique (FOT) is useful in the evaluation of small airway disease in bronchial asthma or chronic obstructive pulmonary disease. We performed the FOT to determine the effect of treatment on bronchocentric granulomatosis and found it to be useful. We report the case of a 55-year-old female with ulcerative colitis who was treated with golimumab and who developed bronchocentric granulomatosis as a sarcoid-like reaction to golimumab. She was successfully treated with prednisone, and the treatment efficacy was confirmed by the FOT. The FOT may be useful in the evaluation of small airway disease in bronchocentric granulomatosis. This case may help inform clinicians of the usefulness of the FOT to assess small airway disease in various diseases., Medicina, 57 (12), art. no. 1315; 2021
