<p>Hydrogel spacers are commonly used to reduce rectal toxicity during radiation therapy for prostate cancer. Although generally safe, rare, serious complications may occur. We report the case of a man with diabetes and renal failure who developed a refractory rectal ulcer and fistula five months after spacer placement, followed by Fournier's gangrene. The patient recovered following surgical drainage and antibiotic therapy. This is the first reported case of Fournier's gangrene following hydrogel spacer insertion. Spacer-related rectal wall infiltration might have contributed to this finding. Clinicians should recognize such adverse events and consider early intervention in high-risk patients presenting with hematochezia or perineal symptoms. </p>

<p><i>Helicobacter pylori</i> <i>(HP)</i> infection is the major cause of gastric cancer (GC). No reports have been published on the effects of <i>HP</i> infection on anxiety for GC, although the majority of <i>HP</i>-positive subjects received eradication therapy intending to reduce their risk of GC in Japan. This study aimed to investigate the relationship between cancer worry (CW) for GC and participants’ <i>HP</i> infection status. The original study was a quantitative, self-administered questionnaire survey to investigate CW for esophageal cancer in Barrett’s esophagus. The present study used the same dataset on CW against GC. Participants were recruited between May 2021 and March 2022 from three health screening facilities in Akita Prefecture, Japan. The Cancer Worry Scale was used to quantitatively assess the fear of developing cancer. Logistic regression analyses were used to investigate factors associated with excessive CW (defined as ≥ 13). A total of 303 respondents were included. Excessive CW accounted for 63.0% (92/146) in <i>HP</i>-negative, 55.0% (11/20) in <i>HP</i>-positive, and 71.5% (98/137) in <i>HP</i>-eradicated patients. While the presence of upper gastrointestinal symptoms and subnormal mental health quality were significantly associated with excessive CW, the status of <i>HP</i> infection did not affect it. There is a significant discrepancy between CW for GC and actual GC risk, defined as their <i>HP</i> infection status, among those undergoing GC screening. It may be necessary to provide appropriate patient education when introducing risk-based (mainly <i>HP</i>-based) stratified screening for GC shortly in Japan.</p>

<p>A 64-year-old woman received a third dose of SARS-CoV-2 mRNA vaccine. On the next day, she developed fever, diarrhea, and abdominal pain and had bloody stools. Total colonoscopy revealed deep ulceration on the whole colon. She was treated with corticosteroid and infliximab and her symptoms improved. She was diagnosed with severe enteritis resembling ulcerative colitis triggered by SARS-CoV-2 mRNA vaccination.</p>
