Pott's puffy tumor is a rare complication of frontal sinusitis characterized by frontal bone osteomyelitis with a subperiosteal abscess typically presenting with forehead swelling. We herein report a 21-year-old man with Pott's puffy tumor presenting as eyelid swelling on the opposite side of the sinusitis, without typical forehead swelling. Initially treated for sinusitis and pre-septal cellulitis with poor response, head magnetic resonance imaging revealed bilateral subdural abscesses and osteomyelitis of the frontal and bilateral parietal bones, leading to the diagnosis. When frontal sinusitis and eyelid swelling are unresponsive to antibiotics, Pott's puffy tumor should be considered, even in the absence of forehead swelling.

Calpainopathy is primarily an autosomal recessive inherited myopathy; however, dominantly inherited cases with a pathogenic variant of c.1333G>A have been reported. A 13-year-old Japanese girl presented with toe walking and elevated serum creatine kinase levels. ⋯ A genetic analysis of her parents revealed the possibility that c.1333G>A was de novo. In this patient, the onset age was earlier than that of the reported autosomal dominant cases, suggesting the influence of the novel variant in the contralateral allele.

A Southeast Asian man in his 30s residing in Japan developed severe disseminated strongyloidiasis during long-term steroid therapy. Initially misdiagnosed as gastroenteritis, his condition was later identified as strongyloidiasis by fecal smears and endoscopy. ⋯ This case underscores the importance of considering the patient's geographical background and immunosuppressive history in medical assessments. It further highlights the need for early and proactive diagnostic approaches, such as stool testing and gastrointestinal endoscopy, to effectively detect and treat imported infectious diseases.

Comparative Study
A Study of the Risk Factors for 402 Patients with Esophageal Squamous Cell Carcinoma - A Retrospective Comparison with Health Checkup Participants.
Objective Esophageal cancer is a gastrointestinal cancer with a poor prognosis. However, it is curable and can be treated endoscopically if it is detected at an early stage. The objective of this study was to identify the factors that contribute to early detection. ⋯ Comparing early and advanced cancers, a history of endoscopic screening was the only factor involved in early detection (OR, 7.93; 95% CI, 4.480-14.000). Conclusion The factors associated with ESCC include alcohol consumption, smoking, concomitant cancer of other organs, and a low BMI. Endoscopy in subjects with these factors may therefore be recommended for the early detection of ESCC.

Objective Elotuzumab plus lenalidomide and dexamethasone (ELd) was approved in Japan in 2016 for the treatment of relapsed/refractory multiple myeloma (RRMM). This post-marketing surveillance study evaluated the safety and effectiveness of ELd in RRMM patients during routine clinical practice in Japan. Methods Elotuzumab safety was assessed by evaluating adverse drug reactions (ADRs), and effectiveness was assessed primarily by the best overall response. ⋯ The presence of comorbidities, particularly cardiovascular disorders, significantly affected the safety. The overall response rate was 41.1%. Conclusion This all-case post-marketing surveillance study showed that ELd had an acceptable tolerability profile and promising clinical activity in Japanese patients with RRMM.
