[A case of pulmonaly bulla infection with Mycobacterium fortuitum].

We report a case of bulla infection caused by Mycobacterium fortuitum. The patient was a 66 year-old female associated with interstitial pneumonitis. The chest X-ray film showed cavities with thick walls and niveau formation, which initially suggested pulmonary abscesses.

[A case of juvenile pulmonary infarction associated with diet therapy].

A 31-year-old man experienced chest pain, fever, bloody sputum and cough after diet therapy. Chest radiography and chest CT showed infiltration in the right lower lung field and right pleural effusion. Pulmonary embolism and infarction was diagnosed using 99mTc-MAA perfusion scans and chest enhanced CT.

[Saprophytic mycosis appearing as a necrotic bronchial tumor and masking lung cancer].

We describe four cases of saprophytic mycosis superficially covering lung cancer to form a bronchial necrotic tumor. Although the first biopsy in each case disclosed mycosis with necrosis, repeated transbronchial biopsy revealed malignant cells. In two of the four cases, we started treatments for lung cancer based on the clinical diagnosis preceding histological diagnosis.

[Clinical evaluation on the duration of hospitalization for patients with pulmonary tuberculosis].

In 1996, six-month short course regimen containing PZA was adopted as the standard method of chemotherapy for tuberculosis. According we reevaluated discharge criteria for patients with pulmonary tuberculosis and tried to shorten the duration of hospitalization. We investigated retrospectively the duration of hospitalization for patients with pulmonary tuberculosis who were admitted to the Tenri Hospital.

[A case of abrupt pulmonary infection by Rhizopus microsporus var. rhizopodiformis during treatment for bronchial asthma].

We presented a case of pulmonary Rhizops microsporus var. rhizopodiformis infection which developed abruptly during treatment of bronchial asthma by systemic corticosteroids. The patient, an 85 year-old-woman, was given systemic steroid therapy for 15 days.
