[Adenocarcinoma with Aplastic Anemia as an Immune-related Adverse Event Caused by Pembrolizumab: Report of a Case].

A 74-year-old man was found a left completely atelectasis on chest X-ray. He had undergone left lower lobe resection because of an adenocarcinoma at the age of 58. Bronchoscopy revealed a tumor near the left upper lobe branch entry that obstructed the lumen, and a biopsy confirmed the diagnosis of adenocarcinoma.

[Multiple Pulmonary Metastases Seven Years After Transurethral Bladder Tumor Resection for Non-muscle Invasion Bladder Cancer:Report of a Case].

A 64-year-old man was admitted because of multiple pulmonary nodules in right upper lobe on chest computed tomography (CT). He had non-muscle invasion bladder cancer resected by transurethral bladder tumor resection seven years ago. Partial resections of the right upper lobe were carried out at the video assisted thracoscopic surgery (VATS) for diagnostic purposes.

Designing the structure and relevant properties of semiclathrate hydrates by partly asymmetric alkylammonium salts.

Semiclathrate hydrates are host-guest materials that form from ionic guests and water. There are numerous options for ionic guests, such as quaternary ammonium salts, to tune the functional properties of these materials such as melting temperature, fusion heat, and gas capacity and selectivity. To design these materials, the stabilization mechanism of the side chains of quaternary ammonium salts must be understood based on both thermodynamic and crystallographic properties and relevant host-guest dynamics.

[Lung cancer incidentally detected at the treatment of pneumothorax ; report of two cases].

We report 2 cases of lung cancer incidentally detected following pneumothorax. Case 1:A 40-year-old man complaining of dyspnea was admitted with right pneumothorax. Chest computed tomography (CT) after chest drainage showed a cavitary nodule with pleural indentations in the right lower lobe.

[Mediastinal goiter; report of a case].

A 76-year-old female was admitted to our hospital because of an abnormal shadow on chest computed tomography (CT) which showed the tumor extending from left lower end of the thyroid to the aortic window along the left side of the trachea, indicating the retrosternal goiter. Serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) were within normal ranges. The tumor was resected through cervical collar incision and median sternotomy.

[Catamenial pneumothorax; report of a case].

A 39-year-old woman was referred to our hospital because of pneumothorax related to menstruation. Chest X-ray showed right pneumothorax. Right thoracoscopy revealed 3 fenestrations on the diaphragm.

[Efficacy of concomitant therapy with S-1, CDGP, and radiation for laryngeal cancer].

Objective: Several clinical trials examining treatment strategies for advanced laryngeal cancer have demonstrated that concurrent chemoradiotherapy is the most effective treatment for improving the patient response to radiotherapy and laryngeal preservation. We evaluated a new regimen of S-1/CDGP(Nedaplatin) with radiotherapy (RT), and established that it represented an effective new treatment option that allowed for the preservation of the larynx.

Methods: A total of 16 patients with stage II to IV laryngeal cancer(excluding T4 stage)who had been treated at our institution from 2001 to 2007 were recruited for the present study.

[Clinical phase trial of concurrent chemoradiotherapy combined TS-1 and nedaplatin].

We have treated head and neck carcinoma by concurrent chemoradiotherapy combined with 5-fluorouracil (5-FU) and cisplatin (CDDP). However,this chemoradiotherapy could not show an enormous effect in the advanced carcinoma of Stage III and IV. Therefore,we changed the contents of the chemotherapy, i.
