Moxifloxacin (MFLX) is a respiratory quinolone, and is effective against not only Gram-positive and negative bacteria but also anaerobes. There has been no prospective studies evaluating the efficacy and safety of MFLX in patients with nursing and healthcare-associated pneumonia (NHCAP). Therefore, we assessed the efficacy and safety of MFLX in patients with NHCAP.

We have retrospectively analyzed the safety of 4 hours administration of liposomal amphotericin B (L-AMB) compared to less than or equal to 3 hours administration in patients with chronic necrotizing pulmonary aspergillosis (CNPA). The elevation of serum creatinine in the group with 4 hours administration of L-AMB in patients with CNPA was equal to the group with shorter administration time (less than or equal to three hours). During the administration of L-AMB, the group with 4 hours administration of LAMB had significantly a safer profile in relation to hypokalemia during L-AMB treatment than the group with shorter administration time.

In order to elucidate the pathology and mechanism of lung toxicity induced by chronic hair spray inhalation, male Wister rats 9 wk of age were exposed to a uniform concentration of hair spray for up to 12 wk using a jet nebulizer. The aerosol concentration to which the rats were exposed was about 7 g/m(3). Differential cell counts in bronchoalveolar lavage fluid (BALF), the expression of several cytokines from alveolar macrophage using the reverse-transcription polymerase chain reaction (RT-PCR) method, and histopathologic evaluation using a computer-aided graphic analyzer (IBAS) were conducted 1, 4, 8, and 12 wk after exposure.

A 50-year-old woman had been treated with propylthiouracil (PTU) for hyperthyroidism. She was admitted to our hospital because of hemosputum, and severe hypoxemia developed. The CT scan showed diffuse infiltration in both lung fields, bronchoalveolar lavage fluid revealed diffuse alveolar hemorrhage, and the level of myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was high; and therefore diffuse alveolar hemorrhage associated with MPO-ANCA positive vasculitis induced by PTU was diagnosed.
