An 84-year-old Japanese man was diagnosed with blastic plasmacytoid dendritic cell neoplasm (BPDCN). We administered combination therapy using venetoclax and azacytidine. ⋯ After six cycles of treatment, the BPDCN abnormal cells in the bone marrow specimen almost disappeared, and atypical cells were not detected in a skin biopsy. We propose venetoclax combined with azacytidine as a useful treatment approach in elderly patients, although clinicians should be mindful that therapeutic modifications may be essential to minimize and/or avoid adverse events.

Objective Sarcopenia is characterized by a loss of muscle mass and strength, which leads to frailty and mortality. Rheumatoid arthritis (RA) is considered to be a cause of sarcopenia. The present study assessed the effectiveness of biological disease-modifying antirheumatic drugs (bDMARDs) on sarcopenia. ⋯ The proportion of patients diagnosed with sarcopenia decreased significantly after 12 months of bDMARDs (43.8% vs. 27.1%, p=0.039). Among the 21 patients who were diagnosed with sarcopenia when starting bDMARDs, the skeletal muscle index was significantly increased after 12 months of bDMARDs. [5.22 (4.76-5.43) kg/m2 vs. 5.44 (4.84-5.77), p=0.039]. Conclusion Biologics may be useful in the treatment of sarcopenia through mechanisms such as improving the disease activity, physical activity and nutritional status.

Observational Study
Rapid Evaluation of Large Vessel Occlusion for Mechanical Thrombectomy Using Carotid Duplex Ultrasound.
Objectives This study clarified the usefulness of carotid duplex ultrasound (CDU) in evaluating large vessel occlusion (LVO) in patients with acute stroke planned to be treated with mechanical thrombectomy (MT). Methods This study was single-center, prospective, observational trial. If the ratio of end-diastolic velocity in the common carotid arteries was ≥1.4, or diastolic flow in the affected internal carotid artery (ICA) was absent on CDU, patients were immediately transferred to the angio-suite without additional cerebrovascular imaging. ⋯ Among the 29 total patients treated with MT, 20 (67%) showed a modified Rankin Scale score ≤2 at 90 days. The door-to-puncture time was significantly shorter in patients evaluated by CDU alone (34 minutes) than in those evaluated by magnetic resonance angiography after CDU (47.5 minutes, p<0.001). Conclusion CDU might reduce the time metrics for early initiation of MT with good sensitivity and specificity in identifying LVO.

A 73-year-old woman with myelodysplastic syndrome and diabetes mellitus, chronic renal failure and paroxysmal atrial fibrillation, received a diagnosis of facial cellulitis and was treated by antibiotics. However, her symptoms deteriorated. Facial magnetic resonance imaging (MRI) showed orbital cellulitis. ⋯ Her symptoms temporarily improved, but she became comatose and died. Results of a molecular analysis of the residual cerebrospinal fluid indicated Rhizopus species infection. For immunocompromised hosts with refractory orbital cellulitis, mucormycosis should be considered as a differential diagnosis, and appropriate treatment should be promptly performed.

Objective The aim of this study was to determine the safety and clinical efficacy of docetaxel+cisplatin+5-fluorouracil (DCF) as neoadjuvant chemotherapy (NAC). Methods In this single-center study, patient background and treatment outcomes (NAC efficacy assessment, NAC adverse events, short-term postoperative outcomes, and one-year postoperative outcomes) in patients treated with preoperative DCF and preoperative cisplatin+5-FU (CF) were compared retrospectively. Patients Seventeen patients diagnosed with esophageal squamous cell carcinoma (ESCC) and treated with preoperative DCF therapy and 50 patients treated with preoperative CF therapy between January 2013 and July 2019 were included in this study. ⋯ The postoperative results [overall survival (OS), recurrence-free survival (RFS), one-year OS, one-year RFS] of the DCF group were comparable to those of the CF group. Conclusion DCF therapy has been recognized as an effective treatment option for advanced ESCC. However, the indication for DCF therapy should be chosen carefully because of the high incidence of adverse events.
