RESUMO

A 79-year-old Japanese man with polymyalgia rheumatica was admitted to hospital with coronavirus disease (COVID-19). On admission, he was treated with ciclesonide inhalation, ivermectin, and meropenem. He was intubated 6 days after admission, and methylprednisolone therapy was initiated (1000 mg/day). Hypoxemia and chest radiographic findings temporarily improved. However, chest computed tomography showed bilateral ground-glass attenuations, multiple nodules, and consolidation. Aspergillus fumigatus was cultured from the tracheal aspirate and he was diagnosed with COVID-19-associated invasive pulmonary aspergillosis (CAPA) and treated with liposomal amphotericin B. However, he died 28 days after admission.

RESUMO

We modified the method of protection to reduce the exposure of health-care workers (droplets) without restricting operability during bronchoscopy. Our method is inexpensive, simple, utilizes disposable materials and prevents interpatient infections. Its routine use during transoral bronchoscopy may be considered due to its simplicity.

RESUMO

Patients with bronchial foreign bodies often present with subjective symptoms, mainly cough, and removing the foreign bodies is difficult. Bronchial foreign bodies are mostly located in the right lower bronchus, and rarely in the right middle bronchus. An 85-year-old man had no subjective symptoms. He aspirated an artificial tooth during dental treatment the day before visiting our clinic, and consulted his home doctor. He was admitted to our hospital because a chest radiograph indicated the presence of a foreign body in the right middle and lower lung field. Chest computed tomography showed that the bronchial foreign body was located in the right middle bronchus, and it was accompanied by an artifact in the circumference of the lesion, and it seemed to be the metal piece of an artificial tooth. Three-dimensional CT showed the root of the artificial tooth located in center side of the right middle bronchus, and, considering the invasiveness, we decided to remove the tooth by flexible bronchoscopy. The bronchoscopy revealed a metal piece occluding the right middle bronchus without granulation, and we could remove the tooth immediately by grasping the root of the tooth with alligator forceps. We experienced a case of a foreign body located in the right middle bronchus without respiratory symptoms. It is important to carry out image examinations, because elderly patients may not exhibit respiratory symptoms.

RESUMO

We report a 79-year-old woman, who had undergone surgery for papillary thyroid carcinoma 18 years previously and lung adenocarcinoma 15 years previously. She didn't receive any follow-up because she had no recurrence for 5 years in both diseases. She visited a local doctor with precordial pain and thorax discomfort as her chief complaints, where chest computed tomography indicated a 14 mm-sized nodule in the right lower lobe and 5-7 mm-sized small nodules in both lungs. Using endobronchial ultrasonography with a guide sheath (EBUS-GS) for the diagnosis in our department, the lesions were confirmed by ultrasonography, and a transbronchial biopsy was carried out under fluoroscopy. Pathologically, a sufficient amount of tumor cells were collected, and the findings of adenocarcinoma were obtained. Her condition was diagnosed as recurrent pulmonary metastases of thyroid papillary carcinoma because of the atypical columnar epithelial cells with nuclear variants and the papillary proliferation of intranuclear inclusion, and because of the positive findings in immunohistochemical staining for thyroglobulin. Since papillary thyroid carcinoma is positive for thyroid transcription factor-1 (TTF-1), which is widely used as a marker of lung adenocarcinoma, it cannot be used to differentiate between the two. It is often difficult to diagnose papillary thyroid carcinoma by bronchoscopy, because its progress is slow and the origin of the metastatic lung tumor is not in the bronchus, unlike primary lung cancer. However, a devised transbronchial biopsy procedure for slowly progressive metastatic lung tumors such as papillary thyroid carcinoma is considered to be a useful technique for diagnosis.

RESUMO

A 37-year-old Japanese man presented with a bulla with niveau-like opacity in the right upper lung on chest radiography. Air-fluid level gradually increased despite broad-spectrum antibiotic therapy. Right upper lobectomy was performed, and epithelioid granuloma with mycobacteria was histopathologically observed. Bacterial culture of the fluid was negative, but mycobacterial culture was positive for Mycobacterium avium; therefore, the patient was diagnosed with pulmonary infected bulla caused by Mycobacterium avium. He was further treated with antimycobacterial agents after resection of the infected bulla. To our knowledge, this is the first report of pulmonary infected bulla caused by only Mycobacterium avium in the English literature.

RESUMO

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been reported to be useful not only for the diagnosis of lymph node metastasis of lung cancer but also for benign diseases. We retrospectively analyzed the results of patients with tuberculous lymphadenitis (TL) who had undergone EBUS-TBNA between November 2010 and January 2016. EBUS-TBNA was performed in 427 cases during that period. Six cases were finally diagnosed as TL. The punctured lymph node was 8 lesions. Pathological findings consistent with TL were obtained in all 6 cases (100%), and the tissue specimens were positive in Ziehl-Neelsen staining in 3 of the 6 cases (50%). In all 6 cases, the acid-fast bacteria (AFB) smear test of the needle rinse fluid was negative, 2 cases were positive for AFB culture (33.3%), and 2 cases were positive for Mycobacterium tuberculosis (MTB)-PCR test (33.3%). In this study, the positive rate of mycobacterial culture and the MTB-PCR test of the needle rinse fluid was low, though the concordance rate of pathological findings with TL was high (100%). The results suggest that EBUS-TBNA should be carefully evaluated in patients with TL, considering the low positive rate of mycobacterial culture and MTB-PCR test in the needle rinse fluid.
