Acute on chronic pancreatitis affecting the ectopic pancreas located in the jejunal mesentery: A case report.

Ectopic pancreas within the mesentery is rare. In this case report, a 61-year-old man with an ectopic pancreas within the jejunal mesentery for over 20 years developed chronic pancreatitis that progressed to acute exacerbation. Our computed tomography (CT) performed for acute abdomen assessment suggested acute appendicitis or Meckel's diverticulitis. However, a CT scan taken 20 years ago revealed a structure indicative of an ectopic pancreas in the mesentery, and further imaging findings taken 10 and 4 years ago confirmed progression to chronic pancreatitis. Furthermore, we found a pancreatic stone confined in the luminal structure that corresponded to the main pancreatic duct; this stone eventually caused acute exacerbation. In summary, we report a case of mesenteric ectopic pancreas that showed typical findings of progression and acute exacerbation of chronic pancreatitis on CT.

Ureteral Diaphragmatic Hernia Treated with Ureteral Stenting: A Case Report and Review of the Literature.

Ureteral diaphragmatic hernia through diaphragmatic defects is an exceptionally rare subset of ureteral hernia with only fourteen such cases reported in English manuscripts. An 85-year-old woman was introduced to our department with right flank pain, fever elevation, and nausea. Urinalysis showed bacteriuria, and Escherichia coli was detected in the urine culture. Blood analysis revealed abnormal findings, including elevated WBC count (10,510/µl) and C-reactive protein (0.28 mg/dl). Computed tomography (CT) of the abdomen demonstrated a defect of the right diaphragmatic crus containing a dilated right ureter with associated hydronephrosis. Retrograde pyelography showed hydronephrosis and dilated ureter loops through the defect of diaphragmatic crus, known as a "curlicue sign," and the diagnosis was right ureteral diaphragmatic hernia. A ureteral stent was placed on her right side, and the ureter was reducted into the retroperitoneal space. After six months, the ureteral stent was removed, with no subsequent recurrence of the ureteral diaphragmatic hernia at seven months. We reviewed all cases in the literature published in English of ureteral diaphragmatic hernia. While the etiology of ureteral diaphragmatic hernia is unknown, our present case and previous reports suggest that a ureteral diaphragmatic hernia may occur due to hepatic atrophy and/or an elevated position of the right kidney.

Clinical application of biological fingerprints extracted from averaged chest radiographs and template-matching technique for preventing left-right flipping mistakes in chest radiography.

We aimed to evaluate the identification performance achieved using biological fingerprints extracted from averaged chest radiographs and template-matching techniques for the prevention of left-right flipping mistakes. We produced averaged chest radiographs for each sex by averaging 100 posteroanterior chest radiographs. Further, 400 and 566 chest radiographs were used in consistency and validation tests, respectively, and they were flipped horizontally to produce flipped chest radiographs under the assumption that the left-right flipping mistake occurred. The correlation values obtained with chest radiographs and those obtained with flipped chest radiographs were calculated. When we used correlation indices calculated from the correlation values from four biological fingerprints except for the lung apex, 96.5% (386/400) and 95.8% (542/566) of the left or right sides were identified correctly in the consistency and validation tests, respectively. This result indicates that our proposed method would be promising for the prevention of left-right flipping mistakes.

Clinical comparison of QOL and adverse events during postoperative adjuvant chemotherapy in outpatients with node-positive colorectal cancer or gastric cancer.

The aim of this study was to evaluate the quality of life (QOL) from the performance status (PS) and face scale (FS), and to compare adverse events (AEs) during chemotherapy in 28 patients with node-positive colorectal cancer (NP-CRC) and 15 patients with node-positive gastric cancer (NP-GC). The anticancer regimen consisted of 5-FU/LV+CPT-11 for NP-CRC and 5-FU+low-dose CDDP for NP-GC. Results were evaluated after completion of three courses. QOL evaluation revealed no significant differences between the two groups with respect to PS and FS. Among hematological AEs, grade 1/2 mild leucopenia was significantly more common in NP-CRC than NP-GC patients (p<0.05), while grade 1/2 mild thrombocytopenia was significantly more common in NP-GC than NP-CRC patients (p<0.05). Among non-hematological AEs, grade 1/2 mild neuropathy (olfactory nerve) was significantly more common in NP-CRC than NP-GC patients (p<0.05). The monthly cost for one course was approximately euro586.8 for NP-CRC patients and approximately euro181.8 for NP-GC patients. These results suggest that first-line postoperative outpatient adjuvant chemotherapy for NP-CRC and NP-GC shows no significant differences with respect to QOL, but both AEs and the cost are higher for NP-CRC than for NP-GC.
