A 45-year-old man was admitted due to tonic seizures, aphasia, disturbance of consciousness, and abnormal behavior. Because cerebral magnetic resonance imaging findings were normal and mild cerebrospinal fluid (CSF) pleocytosis was observed, autoimmune encephalitis was suspected. ⋯ Multimodal immunotherapy was administered, which remarkably improved the level of consciousness. Progressive reversibility of SPECT findings with clinical improvement suggested that the disorder-related functional deficits had been caused by anti-NMDA receptor antibodies.

Objective The early integration of palliative care into standard cancer treatment has become a global standard. The Palliative care Emphasis program on symptom management and Assessment for Continuous medical Education (PEACE) has been conducted in Japan, and previous studies have reported that the PEACE workshop was able to improve various palliative care skills of participants. However, whether or not the effects of the program are long-lasting and if the program consequently changed physicians' practice with regard to lung cancer patients have been unclear. ⋯ The total PCPS and PCDS scores were also significantly better in workshop participants than in non-participants (71.8 versus 67.1 and 34.3 versus 36.9, respectively), although some domains of PCDS were similar between the groups. Conclusion The PEACE program improved the knowledge and practices with regard to palliative care and resolved difficulties associated therewith among lung cancer physicians. In regions where palliative care specialists are insufficient, such educational programs may be effective.

Comparative Study
A Phase II Study of Tailored-dose S-1 Plus Carboplatin Followed by Maintenance S-1 for Advanced Squamous Cell Lung Cancer: OSAKA-LCSG 1102.
Objective A subset analysis of the LETS study suggested that S-1 plus carboplatin was more beneficial than paclitaxel plus carboplatin in terms of the overall survival (OS) in squamous cell lung cancer. However, the benefit of maintenance therapy for squamous cell non-small cell lung cancer (NSCLC) patients is still unknown. We herein report a phase II study to evaluate the efficacy and safety of a tailored dose of S-1 plus carboplatin followed by maintenance S-1 in chemotherapy-naive advanced squamous cell NSCLC. ⋯ Ten patients received maintenance S-1, and the median PFS from the beginning of induction treatment was 5.3 months. Grade 3/4 toxicities with a frequency of more than 5% were all controllable. Conclusion Tailored-dose S-1 plus carboplatin followed by maintenance S-1 is an effective and feasible treatment for advanced squamous cell NSCLC.

Objective Few reports have analyzed the diagnostic process of carcinoma of unknown primary site (CUP) or have focused on the frequency of nonmalignant lesions among patients with suspected malignant diseases. The aim of this study was to investigate the incidence and characteristics of nonmalignant diseases that tend to be mistaken for malignant diseases. Patients We retrospectively analyzed the medical records of patients with suspected CUP who were referred to the National Cancer Center Hospital (Tokyo, Japan) between April 2007 and December 2014. ⋯ Conclusion The incidence of nonmalignant diseases among patients with suspected CUP was 46 out of 830 patients in our institution. It is important to perform a thorough pathological examination in the CUP diagnostic workup. To confirm a diagnosis, some patients may need to visit specialized institutions, especially those with liver and bone lesions.

Objective To prevent the development of overt hepatic encephalopathy, the early intervention for minimal hepatic encephalopathy (MHE) based on an accurate diagnosis is essential. This study investigated whether or not magnetic resonance diffusion kurtosis imaging (DKI) and diffusion tensor imaging (DTI) could detect brain microstructure abnormalities in MHE. The aim was to confirm whether or not brain microstructure abnormalities detected by magnetic resonance (MR) imaging could be used for the diagnosis of MHE. ⋯ The MK in the putamen showed the best diagnostic performance for differentiating the subjects with MHE from those without MHE (cut-off value, 0.74; sensitivity, 0.89; specificity, 0.86). Conclusion DKI detects changes in the cerebral white matter and basal ganglia regions of patients with MHE more sensitively than DTI. The MK values in the putamen can be a useful marker for diagnosing MHE from cirrhotic patients without MHE.
