Leptospirosis is a zoonotic disease. We present a case of acute pancreatitis associated with leptospirosis. An 88-year-old woman was admitted to the hospital with high fever and severe myalgia of the lower extremities. Based on the clinical presentation, hepatic dysfunction with a mild increase in bilirubin, renal dysfunction, and life history, the possibility of leptospirosis was considered. Plain computed tomography of the trunk on admission revealed no special findings. Appropriate antimicrobial therapy was administered at an early stage. After treatment initiation, the clinical symptoms and blood test abnormalities began to improve, and the patient appeared to be doing well. Although no abdominal or back pain was consistently noted during hospitalization, the serum amylase level increased over time; therefore, the patient underwent another computed tomography scan on the ninth day. Acute pancreatitis, which was absent upon admission, was noted. Appropriate treatment for pancreatitis was administered, and the patient was discharged. A subsequent serum antibody test confirmed the diagnosis of leptospirosis. Herein, we also summarized previous cases of acute pancreatitis associated with leptospirosis. The time of onset for pancreatitis was inconsistent, and there were a few cases of pancreatitis without abdominal or back pain. In contrast, serum amylase or lipase levels were elevated in all patients, which could be an important trigger for suspected complications of pancreatitis. When leptospirosis is suspected, complications of pancreatitis should always be considered, even in the absence of apparent abdominal pain. Regular monitoring of pancreatic enzymes such as amylase and lipase is recommended.

BACKGROUND: Symptom scales for achalasia after per-oral endoscopic myotomy (POEM) are lacking. This study aimed to propose a new scale based on the conventional Eckardt score (c-ES) and evaluate persistent symptoms that impair patients' quality of life (QOL) post-POEM. METHODS: Dysphagia, regurgitation, and chest pain frequencies were assessed using a 6-point scale modified-ES (m-ES) after POEM, with "occasional" symptoms on the c-ES further subdivided into three-period categories on m-ES. Symptom severity was further evaluated using a 5-point scale ranging from 1 to 5 points, with a score ≥ 3 points defined as persistent symptoms impairing QOL. We analyzed the correlation between the m-ES and severity score, diagnostic performance of the m-ES for persistent symptoms, and overlaps between each residual symptom. RESULTS: Overall, 536 patients (median follow-up period, 2.9 years) post-POEM were included in this multicenter study. Significant correlations were observed between the m-ES and severity scores for dysphagia (r = 0.67, p < 0.01), regurgitation (r = 0.73, p < 0.01), and chest pain (r = 0.85, p < 0.01). Twenty-six patients (4.9%) had persistent symptoms post-POEM, and 23 of them had m-ES-specific symptom frequency ≥ once a month, which was determined as the optimal frequency threshold for screening persistent symptoms. The total m-ES predicted persistent symptoms more accurately than the total c-ES (area under the curve: 0.95 vs. 0.79, p < 0.01). Furthermore, dysphagia and chest pain were the major residual symptoms post-POEM covering 91.4% of regurgitation. CONCLUSIONS: The new post-POEM scale successfully evaluated the QOL-based patient symptom severities. Our study implied the possibility of a simpler scale using residual dysphagia and chest pain.

Objective: This study aimed to characterize the profiles of the oral and gut microbiota of patients with colorectal polyps using 16S rRNA gene sequencing and bioinformatic approaches. Background: Previous studies have shown microbial translocation from the oral cavity to the gut, implying pathogenic impacts on gastroesophageal disease, including colorectal cancer (CRC). However, its details remain unclear. Methods: Twenty patients scheduled for endoscopic colorectal polypectomy were enrolled in this study. Oral samples (saliva and subgingival dental plaque) and intestinal samples (feces and swab of intestinal mucosa) were collected during preoperative and 6–month–postoperative reassessment periods. After sequencing the V3–V4 region of the bacterial 16S rRNA gene, several bioinformatic analyses (bacterial composition, diversity, core microbiome, and shared ASV) were performed on pre– and postoperative samples for each subject. Results: The bacterial composition was dominated by Bacteroides, Streptococcus, Fusobacterium, Veillonella, and Prevotella_7 in all four samples. Beta diversity analysis using weighted UniFrac distance distinctly segregated the samples between oral and intestinal environments in the principal coordinate analysis plot. Core microbiome analysis revealed that Streptococcus and Porphyromonas were dominantly shared in intra–oral environments. Additionally, alongside Streptococcus, periodontitis–related bacteria, such as Veillonella, Fusobacterium, Porphyromonas, Prevotella_7, Haemophilus, and Prevotella, were identified as shared genera between oral and intestinal environments. Finally, shared ASV analysis demonstrated that Streptococcus was shared in the oral and intestinal environments of most patients, while periodontal pathogens were shared in some patients. Conclusions: The core microbiome and shared ASV analyses revealed that several genes are shared between oral and intestinal environments in patients with colorectal polyps, indicating the oral–gut translocation of periodontitis–related bacteria. Further large–scale studies are needed to elucidate their involvement in CRC.

Several cases of esophageal stenosis caused by cervical vertebral osteophytes have been reported; however, few reports of esophageal stenosis caused by thoracic osteophytes are available. We describe the case of an 86-year-old man with esophageal stenosis caused by a thoracic osteophyte near the tracheal bifurcation. An endoscopic ultrasonography examination was scheduled to determine the cause of acute pancreatitis; however, lacerations observed at the bifurcation following endoscope removal during prior esophagogastroduodenoscopy led us to cancel the ultrasonography to avoid potential esophageal perforation. A review of the present case and six similar previous cases of thoracic osteophyte-associated esophageal stenosis (identified via a systematic search of the PubMed database) demonstrated the clinical importance of a thoracic osteophyte near physiological esophageal stenosis. Esophagogastroduodenoscopy and computed tomography should be performed to screen for vertebral osteophytes before endoscopic ultrasonography, endoscopic retrograde cholangiopancreatography, and transesophageal echocardiography to avoid iatrogenic accidents.
