A high α1-antitrypsin/interleukin-10 ratio predicts bacterial pneumonia in adults with community-acquired pneumonia: a prospective cohort study.

Background: Current microbiological tests fail to identify the causative microorganism in more than half of all pneumonia cases. We explored biomarkers that could be used for differentiating between bacterial and viral pneumonia in patients with community-acquired pneumonia (CAP).

Methods: In this prospective cohort study conducted in Japan, data obtained from adult patients with bacterial pneumonia, including bacterial and viral coinfections (bacterial pneumonia [BP] group), and purely viral pneumonia (VP group) at diagnosis were analyzed using multivariate logistic regression analysis to identify predictors of bacterial pneumonia.

Radon Therapy Is Very Promising as a Primary or an Adjuvant Treatment for Different Types of Cancers: 4 Case Reports.

We report on the application of radon inhalation therapy to patients with 4 types of cancer: colon, uterine, lung, and liver cell. The radon treatments were given to improve the efficacy of chemotherapy and were potent in all 4 cases. Marker values decreased and disease symptoms were alleviated.

Radon Therapy for Autoimmune Diseases Pemphigus and Diabetes: 2 Case Reports.

We report on the application of radon therapy to relieve the suffering of 2 patients with autoimmune diseases, one with pemphigus with an old myocardial infarction and diabetes mellitus and the other with type I diabetes. We include a lengthy discussion of the biological mechanisms that we believe produced the observed benefits. During the 6 to 9 months of the treatments, the marker values decreased to the upper limit of their normal ranges and the symptoms of the diseases were alleviated.

The efficacy and safety of sitafloxacin and garenoxacin for the treatment of pneumonia in elderly patients: A randomized, multicenter, open-label trial.

Oral treatment for elderly outpatients with pneumonia is becoming increasingly important in this super-aged society from the perspective of cost-effectiveness and limited hospital capacities. We evaluated the efficacy and safety of two oral respiratory quinolones, sitafloxacin and garenoxacin, in elderly patients with pneumonia. This randomized, multicenter, open-label trial was conducted among patients aged ≥65 years with clinically and radiographically confirmed pneumonia in Japan.

Recovery From Rheumatoid Arthritis Following 15 Months of Therapy With Low Doses of Ionizing Radiation: A Case Report.

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that occurs commonly in old people. Hot spring radon therapy is widely practiced in Central Europe and Japan for relief from the painful symptoms. The usual duration of a spa treatment is a week or two, and the relief is temporary.

Present and Future Prospects of Radiation Therapy Using α-Emitting Nuclides.

Therapy with α-radiation has issues associated with internal exposure; its clinical use has been avoided. However, phase III clinical tests of the α-emitting nuclide Ra on patients with cancer have been conducted, and results were reported in 2011 to 2012. Since then, research has being carried out on targeted internal therapy by introducing α-emitting nuclides directly into the cancers.

Treatment of Cancer and Inflammation With Low-Dose Ionizing Radiation: Three Case Reports.

There is considerable evidence from experimental studies in animals, as well as from clinical reports, that low-dose radiation hormesis is effective for the treatment of cancer and ulcerative colitis. In this study, we present 3 case reports that support the clinical efficacy of low-dose radiation hormesis in patients with these diseases. First, a patient with prostate cancer who had undergone surgical resection showed a subsequent increase in prostate-specific antigen (PSA).

Studies of non-nucleoside HIV-1 reverse transcriptase inhibitors. Part 2: synthesis and structure-activity relationships of 2-cyano and 2-hydroxy thiazolidenebenzenesulfonamide derivatives.

In a previous study, we described the structure-activity relationships (SARs) for a series of thiazolidenebenzenesulfonamide derivatives. These compounds were found to be highly potent inhibitors of the wild type (WT) and Y181C mutant reverse transcriptases (RTs) and modest inhibitors of K103N RT. These molecules are thus considered to be a novel class of non-nucleoside HIV-1 RT inhibitors (NNRTIs).

Studies of nonnucleoside HIV-1 reverse transcriptase inhibitors. Part 1: Design and synthesis of thiazolidenebenzenesulfonamides.

A random high-throughput screening (HTS) program to discover novel nonnucleoside reverse transcriptase inhibitors (NNRTIs) has been carried out with MT-4 cells against a nevirapine-resistant virus, HIV-1(IIIB-R). The primary hit, a thiazolidenebenzenesulfonamide derivative, possessed good activity. A systematic modification program examining various substituents at the 3-, 4-, and 5-positions on the thiazole ring afforded compounds with enhanced anti-HIV-1 and reverse transcriptase (RT) inhibitory activities.

Clinical evaluation methods for new antimicrobial agents to treat respiratory infections: Report of the Committee for the Respiratory System, Japan Society of Chemotherapy.

The present report constitutes an attempt to improve and modify the existing clinical evaluation method for new antimicrobial agents to treat respiratory infections. One year ago, a general guideline on the clinical evaluation of antimicrobial agents to treat respiratory infections was drafted in Japanese, leaving scope for critical discussion, and this has been translated into English, as there were no major changes. In this report, respiratory infections have been discussed under the headings "acute respiratory tract infection" and pneumonia and acute exacerbation of chronic pulmonary diseases.

Diagnosis of Measles Pneumonia from Bronchoalveolar Lavage Fluid by Reverse-Transcriptase Polymerase Chain Reaction: Case Report.

A 24-year-old male contracted measles during treatment with prednisolone for bronchial asthma and eosinophilic pneumonia. Five days after the appearance of skin eruptions, infiltration shadows were detected in the hilum of the left lung on a chest X-ray and a chest computed tomography revealed diffuse macular and infiltration shadows in both lungs and in the left S6 segment, respectively. Pneumonia complicating measles may be caused by either the measles virus itself or by a secondary bacterial infection.

Clinical and Immunological Evaluation of Infection in Patients on Hemodialysis.

Infection is a major complication associated with increased morbidity and mortality in patients on hemodialysis. We analyzed the incidence and type of infection occurring in 4841 patients on hemodialysis between 1986 and 1993 in our hospital and 11 other hemodialysis centers. Infection was noted in 193 patients (4.
