The utility of topotecan monotherapy for relapsed small-cell lung cancer (SCLC) after failure of amrubicin monotherapy has not been evaluated. We aimed to investigate the efficacy and safety of topotecan monotherapy in patients with relapsed SCLC after amrubicin monotherapy. We retrospectively analyzed data from 16 patients with relapsed SCLC who were treated with topotecan monotherapy after amrubicin monotherapy at our hospital.

We previously reported a 39-year-old man who presented with pulmonary and cerebral Cryptococcus gattii (genotype VGIIa) infection and was successfully treated with liposomal amphotericin B and flucytosine induction therapy. Following induction therapy, oral fluconazole treatment was initiated as consolidation therapy. However, the patient complained of progressively worsening headache, presenting an elevated cerebrospinal fluid (CSF) cell count.

Background/aim: The utility of nanoparticle albumin-bound paclitaxel (nab-PTX) monotherapy in patients with relapsed small-cell lung cancer (SCLC) has not been fully evaluated. We aimed to investigate the efficacy and safety of nab-PTX monotherapy in relapsed SCLC patients, including heavily treated patients.

Patients And Methods: We retrospectively analysed data from 17 patients with relapsed SCLC who were treated with weekly nab-PTX monotherapy at our hospital.

Background: Several reports have described the importance of immunological and nutritional factors in the morbidity and/or mortality of patients with tuberculosis. The aim of this study was to evaluate the association between pulmonary cavitation and immunonutritional status, assessed by parameters such as neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI), in patients with pulmonary tuberculosis.

Methods: We retrospectively analyzed the data of 137 patients with culture-positive active pulmonary tuberculosis without bacterial pneumonia diagnosed at Kainan Hospital between April 2008 and March 2016.

A 90-year-old woman was referred to our hospital because of dyspnea with pleural effusion that was detected using a chest X-ray. Pleural fluid cell block specimens from the left pleural effusion were shown to be an adenocarcinoma harboring an epidermal growth factor receptor(EGFR)gene mutation(L858R). Erlotinib was administered and the patient responded to treatment for 15 months.

An 81-year-old man was referred to our hospital with bilateral multiple patchy opacities on chest radiography. His chief complaints were a few months' history of intermittent mild cough and slightly yellow sputum. Chest computed tomography (CT) showed non-segmental air-space consolidations with ground-glass opacities.

A 67-year-old man was admitted to our hospital complaining of dry cough. Chest computed tomography showed diffuse infiltrates and ground-glass opacities in the bilateral lung fields. Transbronchial lung biopsy specimens showed alveoli filled with yeast-like fungi.

Background/aim: It remains challenging to select patients with non-small cell carcinoma (NSCLC) for nivolumab monotherapy. We evaluated whether early termination of nivolumab monotherapy correlated with pretreatment neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI).

Patients And Methods: Twenty patients received nivolumab monotherapy for NSCLC with wild-type epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) during 2016.

With the recent decrease in the number of tuberculosis wards and increase in elderly tuber- culosis patients with comorbidities, the role of regional refer- ral hospitals has become more important in tuberculosis management. [Objective]. This study aimed to assess the current state of tuberculosis management and related issues in a general hospital lacking a tuberculosis ward.

Background: Pretreatment serum tumor marker levels predict outcome in non-small cell lung cancer (NSCLC). However, little is known about the clinical value of such measurements for patients treated with pemetrexed plus a platinum-derivative.

Patients And Methods: We retrospectively screened 100 chemotherapy-naïve patients with advanced non-squamous NSCLC treated with pemetrexed plus a platinum-derivative in relation to the pretreatment level of cytokeratin 19 fragment (CYFRA 21-1) and carcinoembryonic antigen (CEA).

Diagnosing active tuberculosis in elderly patients presents problems due to nonspecific symptoms and complications such as aspiration pneumonia. The current study presents two cases of pulmonary tuberculosis with bilateral pulmonary infiltrates associated with aspiration pneumonia. The two elderly patients developed acute respiratory distress syndrome as a result of aspiration pneumonia.

A 71-year-old man with myelodysplastic syndrome (MDS) was admitted to our hospital because of recurrent high-grade fever. He was examined for bacterial and fungal infections and treated with antibiotics and antifungal agents. However, he did not achieve a definitive diagnosis and had no apparent improvement for more than a month.

The efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in elderly patients with non-small-cell lung cancer (NSCLC) remains uncertain. This retrospective study aimed to evaluate the efficacy and feasibility of EGFR-TKIs for NSCLC patients aged ≥ 80 years. We analyzed data from 21 NSCLC patients aged ≥ 80 years who were administered gefitinib and/or erlotinib between January, 2009 and December, 2014.

A 35-year-old woman was referred to our hospital because of an abnormal finding on a chest X-ray film. Chest and abdominal computed tomography (CT) revealed a 25 × 5-mm tumor in the anterior right third rib as well as punched-out lesions in the vertebral bodies and iliac bones. Positron emission tomography (PET)/CT revealed accumulation in the right third rib and lumbar vertebral bodies.

A 77-year-old woman with hypertension and senile depression had suffered from medically unresponsive trigeminal (left ophthalmic) neuralgia despite microvascular decompression surgery for twice. The patient underwent stereotactic gamma knife radiosurgery (77 Gy) for the neuralgia, resulting in pain relief. However, approximately 20 months after the radiosurgery, she developed left facial palsy with hydrodipsia, left xerophthalmia, and left facial hypesthesia.
