Distance and oxygen desaturation in 6-min walk test predict prognosis in COPD patients.

The aim of the present study was to predict the prognosis of Chronic obstructive pulmonary disease (COPD) patients who underwent comprehensive pulmonary rehabilitation (PR). A total of 144 patients who performed PR between 1992 and 1999 was assessed. After PR, 67 patients underwent lung volume reduction surgery (LVRS).

Comprehensive pulmonary rehabilitation according to severity of COPD.

A new classification for the severity of COPD was proposed at GOLD 2003: stage I: FEV(1) > or = 80% predicted; stage II: 50% < or = FEV(1)<80%; stage III: 30% < or = FEV(1)<50%; and stage IV: FEV(1) < 30%. To elucidate the acute effects of pulmonary rehabilitation (PR) on patients with different stages of COPD, data on pulmonary function, arterial blood gas analysis, the 6-min walk test, respiratory muscle strength, and activities of daily living were analyzed before and after our comprehensive 4- to 8-week inpatient PR program between 1992 and 2003. A total of 225 patients (201 men and 24 women; 21 with stage II, 79 with stage III, and 125 with stage IV COPD) was assessed.

A phase I and pharmacological study of amrubicin and topotecan in patients of small-cell lung cancer with relapsed or extensive-disease small-cell lung cancer.

Cisplatin-based chemotherapy is considered to be a standard treatment in patients with relapsed or extensive-disease (ED) small-cell lung cancer (SCLC), the survival benefit remains modest. Relapsed or ED-SCLC patients were enrolled. Topotecan and amrubicin were administered on Days 1-5 and on Days 3-5, respectively.

[In vitro antituberculous activity of ofloxacin and levofloxacin against multidrug-resistant tuberculosis and clinical outcomes].

Objective: To investigate in vitro antituberculous activity of ofloxacin (OFLX) and levofloxacin (LVFX) against multidrug-resistant tuberculosis and to study the clinical outcomes.

Subjects And Methods: In vitro antituberculous activity of OFLX and LVFX against multidrug-resistant strains of Mycobacterium tuberculosis isolated from 46 patients with pulmonary tuberculosis and a retropective clinical analysis of 45 patients were investigated.

Results: In susceptibility testing, resistance rates to OFLX or LVFX were higher in intractable cases (7/20: 35%) and in cases with prior chemotherapy using new quinolones (5/12: 42 %).

[Antimycobacterial susceptibility against nontuberculous mycobacteria using brothmic NTM].

Purpose: Recently the incidence of pulmonary nontuberculous mycobacteria infection has increased among patients not only implicated with AIDS, but also without predisposing conditions. However, an effective antimicrobial therapy for the disease has not been established yet, because of the absence of highly active therapeutic drugs. We compared the in vitro antimicrobial activities of five antituberculous drugs, clarithromycin and fluoroquinolones against 92 clinical isolates belonging to three species of slowly growing nontuberculous mycobacteria.

[Clinical experience with a new synthetic retinoid, tamibarotene (Am-80) for relapsed or refractory acute promyelocytic leukemia].

A new synthetic retinoid, Am-80 is expected to overcome all-trans retinoic acid (ATRA) resistance, because of several times more potent differentiation activity than ATRA and sustained plasma level during continuous administration due to a lower affinity for cellular retinoic acid binding protein. In a preliminary study in Japan, 14 (58%) of 24 acute promyelocytic leukemia (APL) patients who had relapsed from ATRA induced complete remission (CR) achieved a second CR. Of these 14 CR patients, 4 of 6 who underwent allogeneic stem cell transplantation (SCT) are alive, and 4 of 8 patients who received only chemotherapy are alive without relapse for >4 years.

[Elderly patient with varicella-zoster virus-associated hemophagocytic syndrome refractory to steroid therapy].

We experienced a case of virus-associated hemophagocytic syndrome (VAHS) after varicella-zoster virus (VZV) infection. The patient, a 101-year-old man, presented with anemia, thrombocytopenia and jaundice two weeks after successful antiviral treatment for the VZV. Histiocytes were detected in the bone marrow examination (2.

Successful treatment of a patient with severe Churg-Strauss syndrome by a combination of pulse corticosteroids, pulse cyclophosphamide, and high-dose intravenous immunoglobulin.

A 24-year-old woman with a 4-year history of bronchial asthma suffered from bloody sputum, numbness of the extremities, elevated eosinophil count, and hypoxemia. A diagnosis of alveolar hemorrhage was made by bronchoalveolar lavage. Echocardiogram revealed severe hypokinesis of the left ventricular wall.

Rapidly progressed acquired immunodeficiency syndrome dementia complex as an initial manifestation.

We report a patient with acquired immunodeficiency syndrome dementia complex (ADC) that presented human immunodeficiency virus infection as an initial manifestation. A 34-year-old man developed disturbance of consciousness and severe abulia over 3 months. The CD4 lymphocyte count was 7.

Influence of repetitive transcranial magnetic stimulation on disease severity and oxidative stress markers in the cerebrospinal fluid of patients with spinocerebellar degeneration.

Ataxia severity, cerebellar hemispheric blood flow (CHBF), ascorbate free radical (AFR), superoxide dismutase protein, superoxide scavenging activity, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in cerebrospinal fluid (CSF) were compared before and after an 8-week course of repetitive transcranial magnetic stimulation (rTMS) in 20 patients with spinocerebellar degenerations (SCD). SCD patients showed higher AFR, 8-OHdG, and superoxide scavenging activity than 19 controls. In SCD patients, AFR and ataxia severity declined, and CHBF increased after rTMS.

Oxidative stress and metal content in blood and cerebrospinal fluid of amyotrophic lateral sclerosis patients with and without a Cu, Zn-superoxide dismutase mutation.

Hydroxyl radical, ascorbate free radical, superoxide dismutase (SOD) activities, Cu,Zn-SOD protein, Mn-SOD protein, 8-hydroxy-2' -deoxyguanosine (8-OHdG) and metals were compared in red blood cells (RBC), plasma and/or cerebrospinal fluid (CSF) between patients with sporadic amyotrophic lateral sclerosis (SALS), familial ALS (FALS) showing the Leu126Ser mutation in the Cu, Zn-SOD gene and controls. In patients with FALS or SALS, concentrations of hydroxyl radical in blood and ascorbate free radical and 8-OHdG in CSF were higher than control group values, while SOD activities in RBC and CSF were lower. In contrast, Cu, Zn-SOD protein concentrations in RBC were low only in FALS patients.

[Pulmonary tuberculosis case with consistant findings of endobronchial spread in chest roentogenography for about three years: a case report].

We reported a case of pulmonary infection by Mycobacterium tuberculosis complicated by endobronchial spread. Chest roentogenography and CT for an 85-year-old male complaining of cough showed endobronchial spread in right upper lung field. His sputum culture for eight weeks showed 10-20 colonies of Mycobacterium tuberculosis.
