Total baseline tumor size predicts survival among patients with advanced small-cell lung cancer receiving chemotherapy plus programmed death-ligand 1 inhibitor as first-line therapy: a multicenter retrospective observational study.

Introduction: Total baseline tumor size (BTS) is a prognostic factor for programmed death 1 and programmed death-ligand 1 (PD-L1) inhibitor treatments. However, the prognostic value of total BTS for patients with small-cell lung cancer (SCLC) who receive chemotherapy plus PD-L1 inhibitor remains unknown. Thus, in this study, we aimed to determine whether total BTS is associated with prognosis in patients with SCLC who receive chemotherapy plus PD-L1 inhibitor as first-line therapy.

Factors for Predicting Outcomes among Non-HIV Patients with Pulmonary Tuberculosis.

Objective Onodera's Prognostic Nutritional Index (PNI), determined as "10× albumin (g/dL) + 0.005× lymphocyte count (/μL)," was originally designed to determine the risk of complications following gastrointestinal surgery. This single-center, retrospective observational study was designed to investigate whether or not the PNI can predict the treatment outcome.

Diagnostic test accuracy of loop-mediated isothermal amplification assay for Mycobacterium tuberculosis: systematic review and meta-analysis.

Diagnostic test accuracy of the loop-mediated isothermal amplification (LAMP) assay for culture proven tuberculosis is unclear. We searched electronic databases for both cohort and case-control studies that provided data to calculate sensitivity and specificity. The index test was any LAMP assay including both commercialized kits and in-house assays.

Digital PCR assay detection of circulating Mycobacterium tuberculosis DNA in pulmonary tuberculosis patient plasma.

Nucleic acid amplification tests are a major diagnostic tool for pulmonary tuberculosis (PTB). Recently, digital PCR (dPCR) assay has improved sensitivity for the detection of small copy numbers of target molecules. The aim of this study is to explore the utility of dPCR for detecting Mycobacterium tuberculosis (MTB) DNA in PTB patient plasma.

Diagnostic test accuracy of anti-glycopeptidolipid-core IgA antibodies for Mycobacterium avium complex pulmonary disease: systematic review and meta-analysis.

Currently, an anti-glycopeptidolipid (GPL)-core IgA antibody assay kit for diagnosing Mycobacterium avium complex (MAC) is commercially available. We conducted this systematic review and meta-analysis to reveal the precise diagnostic accuracy of anti-GPL-core IgA antibodies for MAC pulmonary disease (MAC-PD). We systematically searched reports that could provide data for both sensitivity and specificity by anti-GPL-core IgA antibody for clinically diagnosed MAC-PD.

Amrubicin for relapsed small-cell lung cancer: a systematic review and meta-analysis of 803 patients.

Currently, amrubicin is permitted for relapsed small-cell lung carcinoma (SCLC) only in Japan. The efficacy and adverse effects of amrubicin as reported by previous studies varied greatly. The inclusion criterion was a prospective study that was able to provide data for efficacy and safety by the AMR single agent regimen as second-line chemotherapy for a patient with SCLC.

Sensitivity and specificity of Cobas TaqMan MTB real-time polymerase chain reaction for culture-proven Mycobacterium tuberculosis: meta-analysis of 26999 specimens from 17 Studies.

Since 2010, studies on the diagnostic accuracy of COBAS TaqMan MTB (CTM) have been frequently reported with an unignorable discrepancy. The key inclusion criterion for this systematic review was original studies that could provide sufficient data for calculating the sensitivity and the specificity of CTM for M tuberculosis (TB) or M tuberculosis complex. The reference test was Mycobacterium culture.

Topotecan for Relapsed Small-cell Lung Cancer: Systematic Review and Meta-Analysis of 1347 Patients.

Topotecan is the most reliable chemotherapy regimen for relapsed small-cell lung carcinoma (SCLC). The efficacy and adverse effects of topotecan as reported by previous studies varied greatly. The inclusion criterion was a prospective study that was able to provide data for 6-month over-all survival (OS) rate, 1-year OS rate, objective responses, and/or adverse effects of single agent topotecan as a second line chemotherapy for SCLC, written in English language as a full article.

[Comparison of drug-induced hepatitis occurring in elderly and younger patients during anti-tuberculosis treatment with a regimen including pyrazinamide].

Background: In Japan, tuberculosis (TB) patients aged over 80 years are usually treated with a regimen not including pyrazinamide (PZA) because of the risk of drug-induced hepatitis.

Purposes: The purpose of this study was to investigate the occurrence of drug-induced hepatitis in TB patients over 80 years of age, who are treated with a regimen including PZA, and compare the findings with those of younger patients. [Methods] Thirty-six patients with pulmonary tuberculosis, who were admitted to Yokohama City University Hospital between June 2011 and March 2012 were included.

Decreased activities of daily living is a strong risk factor for liver injury by anti-tuberculosis drugs.

Background And Objective: We evaluated the association between activities of daily living and drug-induced liver injury by anti-tuberculosis drugs.

Methods: This retrospective cohort study included adult inpatients with newly diagnosed smear-positive lung tuberculosis treated with standard regimen in two hospitals. (n = 346; 63.

[Two cases of juvenile-onset and adult-onset recurrent respiratory papillomatosis].

We recently experienced one each of 2 types of recurrent respiratory papillomatosis (RRP). Case 1 (juvenile-onset type): A 30-year-old woman presenting with bloody sputum and large tumors with cavities on her chest Xray film, was referred to our hospital. She had been diagnosed with laryngeal papillomatosis when she was three years old.

Choroidal metastasis with adenocarcinoma of the lung treated with gefitinib.

Purpose: To report a case of bilateral regression of choroidal metastasis with adenocarcinoma of the lung treated with gefitinib.

Methods: Retrospective case review of a 68-year-old woman with pulmonary adenocarcinoma with choroidal metastasis who presented with visual loss in the left eye as the initial manifestation. Her visual acuity was 6/6 in the right eye and 6/60 in the left eye before the start of gefitinib administration.

[A case of lymphocytic interstitial pneumonia complicated with primary Sjögren's syndrome followed by chest CT scanning for thirteen years].

We encountered a rare case of lymphocytic interstitial pneumonia (LIP) complicated with primary Sjögren's syndrome (SjS), followed by chest CT scanning for a long period of time. A 54-year-old man with hemoptysis was admitted to our hospital in December, 2001. A diagnosis of SjS was made based on elevation of anti-SS-B/La antibody titer in serum in combination with diagnosis of keratoconjunctivitis sicca and xerostomia on a Schirmer test and a lip biopsy, respectively.

A case of Poncet's disease (tuberculous rheumatism).

We describe a 37-year-old woman with recurrent polyarthritis, and recurrent erythema nodosum on the flexible side of her left forearm. On an X-ray of the chest, infiltration of the right upper lobe was observed. Transcription-reverse transcription concerted reaction in sputum samples revealed Mycobacterium tuberculosis (M.

[A case of interstitial pneumonia after S-1 administration for gastric cancer].

An 80-year-old man with no history of thoracic radiotherapy nor interstitial pneumonia was administered S-1 for gastric cancer in June 2007. Twenty-two days after starting S-1, he had dyspnea, and X-rays showed reticular shadows in both lung fields, yielding a diagnosis of interstitial pneumonia. Drug lymphocyte stimulating test (DLST) was positive against S-1.
