    Cancer vaccines and immune checkpoint inhibitors (ICI) have recently been employed as immunotherapies for esophageal squamous cell carcinoma (ESCC). Cancer vaccines for ESCC have yielded several promising results from investigator-initiated phase I and II clinical trials. Furthermore, a Randomized Controlled Trial as an adjuvant setting after curative surgery is in progress in Japan. On the other hand, ICI, anti-CTLA-4 mAb and anti-PD-1 mAb, have demonstrated tumor shrinkage and improved overall survival in patients with multiple cancer types. For ESCC, several clinical trials using anti-PD-1/anti-PD-L1 mAb are underway with several recent promising results. In this review, cancer vaccines and ICI are discussed as novel therapeutic strategies for ESCC.

    Background: Laminoplasty is widely accepted as a standard treatment of cervical compressive myelopathy. However, due to the risk of postoperative complications such as neck symptoms, segmental partial laminectomy (SPL) is performed instead, which results in fewer postoperative symptoms. The aim of this study was to describe the difference in the incidence and severity of postoperative neck symptoms between traditional C3-C7 expansive open-door laminoplasty (ELAP) and SPL.

    Methods: A retrospective and comparative study was performed regarding neck complications following the two surgical procedures. Twenty patients underwent SPL, and an additional 20 age- and gender-matched patients underwent traditional C3-C7 ELAP. Preoperative and postoperative JOA scores were measured, and postoperative neck symptoms in both groups were evaluated using a self-administered questionnaire, according to the Neck Pain and Disability Scale.

    Results: The total incidence of postoperative neck symptoms in the SPL group was similar to that in the ELAP group; however, the severity of symptoms was remarkably lower in the SPL group than in the ELAP group.

    Conclusions: SPL seems to be a better procedure for reducing postoperative neck symptoms, when compared with C3-C7 ELAP.

    Background: Breath acetone is reported to be a noninvasive biomarker for heart failure. However, the measurement of this metabolite requires expertize and is not standardized yet. Acetone is also released from the skin; thus, measuring acetone as a skin gas may be easier than breath analysis.

    Methods: We analyzed skin acetone collected from 41 hospitalized patients with cardiovascular diseases. Passive samplers were used to measure skin acetone emission. Passive sampler was softly fixed on the surface of forearm skin for 10 hour at night.

    Results: Skin acetone emission ranged from 0.00 to 2.70 ng/cm2/h, and was significantly correlated with blood ketone bodies (r = 0.377, p = 0.017).

    Conclusions: This is the first study to analyze skin gas in patients with cardiovascular diseases. Skin acetone emission was found to reflect blood ketone bodies. It is feasible to measure skin acetone emission for reflecting blood ketone bodies in patients with cardiovascular diseases.

    Aims: We aimed to investigate the relationship of colorectal cancer prognosis and inflammatory parameters, including neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR), with reference to circulating myeloid-derived suppressor cells (MDSCs) in the current study.

    Patients and Methods: Thirty-five patients who underwent curative-intent surgery were enrolled. A receiver-operating characteristic curve (ROC) was used to assess the usefulness of candidates for prognostic factors. Recurrence-free survival (RFS) was calculated using the Kaplan-Meier method, and the candidates for prognostic factors were assessed by a Cox proportional hazard model.

    Results: ROC curve analyses determined cutoff values for NLR and LMR as 2.9 and 2.4, respectively. The percentage of MDSCs in patients with LMR ≤ 2.4 was statistically higher than in those with LMR > 2.4 (p = 0.012). The patients with LMR ≤ 2.4 exhibited a statistically lower RFS than those with LMR > 2.4 (p = 0.008). These results were also observed in patients with stage II + III disease. LMR was an independent prognostic factor of RFS in colorectal cancer patients (hazard ratio: 7.757, 95% confidence interval: 1.462-41.152, p = 0.016).

    Conclusion: Lower LMR was associated with poor prognosis in colorectal cancer patients; whereas, higher circulating MDSCs were observed in patients with lower LMR.

    Background: Cervical spondylotic radiculopathy (CSR) is a relatively common neurological disease caused by the mechanical compression of nerve roots. Limaprost, a prostaglandin E1 derivative, functions as a vasodilator and has been used in the treatment of lumbar spinal stenosis in Japan. However, the effects of limaprost in cervical radiculopathy remain unclear. Our aim was to compare the efficacy of limaprost with that of pregabalin, which is widely used for the treatment of neuropathic pain.

    Methods: In this randomized trial, patients with CSR received either limaprost or pregabalin orally for 8 weeks, along with nonsteroidal anti-inflammatory drugs. The primary outcomes were assessed using a numerical rating scale of pain and numbness, both at rest and during movement. Secondary outcomes were assessed using Short Form-36, provocation tests, painDETECT questionnaire, and subjective global assessment. The obtained data were evaluated according to the per-protocol analysis principle.

    Results: A total of 46 patients were enrolled in this study, and 35 were available for analysis. A greater reduction in pain score was observed in neck pain during movement, and scapular and arm pain both at rest and during movement in the pregabalin-treated group up to 4 weeks. In the limaprost-treated group, numbness of the arm during movement showed a marked alleviation compared to the pregabalin-treated group at 8 weeks. There were no apparent differences between the two groups in terms of the secondary outcomes.

    Conclusions: Although pregabalin provided an earlier pain relief than limaprost, limaprost was superior to pregabalin in treating arm numbness. Limaprost might be one of the effective therapeutic options for CSR in primary care settings.

    Lymphoproliferative disorder (LPD) is a potentially severe adverse effect of methotrexate (MTX) administration in patients with rheumatoid arthritis (RA). We report a case of MTX-associated LPD (MTX-LPD) in a patient with RA who developed severe pulmonary failure complicated by perforation of the terminal ileum. A 61-year-old woman with RA receiving MTX complained of dyspnea and abdominal pain. She was diagnosed with intestinal perforation and peritonitis, and underwent immediate abdominal surgery. Pathological examinations of the specimen obtained from the resected ileum and a bone marrow aspirate revealed diffuse large B-cell lymphoma. Steroid therapy failed to improve her respiratory failure, but her condition improved after abdominal surgery and suspension of MTX. MTX-LPD can result in multiple life-threatening conditions; however, the symptoms are highly variable. RA patients receiving MTX should thus be monitored carefully, and MTX administration should be stopped immediately on suspicion of MTX-LPD.

    Anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive clinically amyopathic dermatomyositis (CADM) is frequently associated with rapidly progressive interstitial lung disease (RP-ILD) resulting in high mortality. Here we report a 51-year-old Japanese woman with anti-MDA5 antibody-positive hypomyopathic dermatomyositis (DM) who developed RP-ILD. She developed respiratory failure and pneumomediastinum, however her RP-ILD responded favorably to the combined immunosuppressive treatments consisting of steroids, intravenous cyclophosphamide and tacrolimus. She was complicated with severe infections, which were successfully managed by combined modality therapy including artificial ventilation and antibiotics in addition to immunosuppressive treatments in parallel to the decline of anti-MDA5 antibody titer (>150 Index to 75 Index). She was discharged after 6 months of treatment without any respiratory sequelae. Hypomyopathic DM patients with high titers of anti-MDA5 antibody should be treated with aggressive immunosuppressive therapies and closely monitored to prevent various infections.

    A 29-year-old man with fever and right upper quadrant pain was referred to our hospital. Ultrasonography revealed intense gallbladder edema and pericardial effusion. Despite no symptoms and signs related to heart failure, the patient was clinically suspected of cardiac dysfunction related to acute peri-myocarditis based on his symptoms of preceding fever and headache, pericardial effusion, positive troponin T value, elevated B-type natriuretic peptide level, and sequential changes on electrocardiography. With a profound eosinophilic surge (8,022/µL) during convalescence, acute peri-myocarditis and gallbladder edema resolved spontaneously. This case instructively shows that acute peri-myocarditis initially manifests with abdominal symptoms, mimicking acute acalculous cholecystitis. In addition, an extensive review of acute myocarditis cases with peripheral eosinophilia suggests that there is a subgroup characterized by a predilection for young and middle-aged men, concurrence of pericardial effusion, transient eosinophilic surge during convalescence, and favorable outcome.
