BACKGROUND The Japanese Respiratory Society guidelines propose a differential diagnosis for atypical pneumonia and bacterial pneumonia using a scoring system for the selection of appropriate antibiotic. In order to improve this scoring system, the guidelines are seeking new specific parameter. The purpose of this study was to clarify the pattern of(More)
The present authors assessed risk factors that can promote indeterminate results of QuantiFERON TB-2G (QFT-2G; Cellestis Ltd, Carnegie, Australia) tests. The subjects were 704 patients with suspected tuberculosis (TB) and latent TB infection between January 2005 and December 2007. The QFT-2G test and the tuberculin skin test (TST) were performed for all(More)
We report a peculiar case of multifocal micronodular pneumocyte hyperplasia (MMPH) in a 54-year-old woman with tuberous sclerosis complex (TSC) diagnosed during antituberculous treatment. Findings were initially detected by chest computed tomography (CT) to check for complication of pulmonary tuberculosis. Chest CT demonstrated multiple small nodules with(More)
OBJECTIVE To evaluate the clinical utility of the T-SPOT.TB test for patients with indeterminate results on the QFT-2G test. MATERIALS AND METHODS Forty patients (10.6%) showed indeterminate results among 378 patients who underwent QFT-2G test because active TB disease was clinically suspected. T-SPOT.TB test was performed for these 40 patients before the(More)
BACKGROUND AND OBJECTIVE This study investigated the clinical and pathological findings of lung disease in tuberous sclerosis complex (TSC) as previously reported in Japan. METHODS The clinical and pathological findings in 15 patients diagnosed as having multifocal micronodular pneumocyte hyperplasia (MMPH) with TSC were analysed. RESULTS The majority(More)
OBJECTIVE To evaluate transitional changes in QuantiFERON TB-2G (QFT-2G) test results in the serial testing on the same patients and to reevaluate the optimal threshold of positive response of QFT-2G test as a cure of TB infection. METHODS We prospectively investigated transitional changes of QFT-2G test results in 22 patients with active tuberculosis(More)
We have postulated that reduced hepatic blood flow is the primary factor responsible for postoperative hepatic insufficiency, and have shown the usefulness of the hepatic blood flow index (KL) estimated by 198Au colloid. However, 198Au colloid has became unavailable due to its intense exposure activity. Therefore, we prepared 111In colloid as a substitute(More)
A 60-year-old man with poorly controlled bronchial asthma was proposed for an emergency appendectomy. His preoperative chest X-P revealed that his left lung was completely collapsed with pneumothorax, but its onset was unclear. Following the left thoracocentesis, appendectomy was performed under general anesthesia (oxygen-halothane). About one hour after(More)
BACKGROUND To grasp the asthma patients' control level, an asthma control test (ACT), an easy questionnaire, is getting to be used as the alternative method of asthma diary recording. ACT is based on the patient's 4-week memory and the accuracy is not confirmed thoroughly METHODS Two hundred and eighty three visits of 88 asthmatics (male 29, female 59)(More)
