Patients with non-muscle-invasive bladder cancer (NMIBC) who are at high and very high risk of disease progression are recommended for radical cystectomy (RC). However, the impact of neoadjuvant chemotherapy (NAC) on survival outcomes in NMIBC patients undergoing RC remains unclear. Patients diagnosed with T1 high-grade NMIBC who underwent RC were identified from the Surveillance, Epidemiology, and End Results (SEER) database. ⋯ Subgroup analysis revealed a survival benefit of NAC in patients with lymph node metastasis. In summary, the results of this study suggest that NAC has the potential to confer a survival advantage in patients diagnosed with T1 high-grade NMIBC who undergo RC, but additional studies are needed. Nonetheless, the survival benefits of NAC in patients with lymph node involvement are apparent.

Polycythemia vera (PV) diagnosis remains a difficult task despite various updates in the 2016 World Health Organization (WHO) diagnostic criteria compared to 2008 criteria. This study aimed to examine the biochemical and clinical features of patients diagnosed with PV using the WHO 2016 criteria but would have been missed by the WHO 2008 criteria, and to ascertain the impact of the lowered thresholds on PV diagnosis. A total of 229 patients with suspected myeloproliferative neoplasms were included in this cross sectional study. ⋯ The groups were similar in terms of chronic obstructive pulmonary disease/obstructive sleep apnea syndrome, spleen status, smoking status, and mean corpuscular volume, white blood count, neutrophil, eosinophil and platelet values. red blood cells and lactate dehydrogenase values were significantly higher, while lymphocyte counts were significantly lower in Group B. With the introduction of WHO 2016 criteria, we found a significant increase in the number of patients who were candidates for PV testing and were ultimately diagnosed with PV. These findings support the diagnostic value of the 2016 WHO criteria, and by extension, the lowered thresholds for detection of patients requiring further analysis.

The aim of this study was to clarify or determine any possible association between pain reports with a visual analogue scale (VAS) and a figures based scale. This research was a preliminary study aimed at developing a new pain scale without any verbal description. Healthy Japanese patients aged 20 to 39 years who received anesthetic injections for mandibular third molar extraction at our department were enrolled. ⋯ Furthermore, patients who chose a cross also reported higher VAS scores than those who chose other figures. Acute pain caused by local dental anesthesia was associated with triangles, and patients who selected a cross were associated with higher VAS scores. The results of this study provide clinicians with important information for dental practice, and could prove useful in developing new pain scales.

Laparoscopic pancreaticoduodenectomy (LPD) is a classic surgical method for diseases, such as tumors at the lower end of the common bile duct, pancreatic head, and benign and malignant tumors of the duodenum. Postoperative pancreatic fistula (POPF) is one of the most serious complications of LPD. To reduce the incidence of grade B or C POPF and other complications after LPD, we applied a split pancreatic duct stent combined with the characteristics of internal and external stent drainage. ⋯ The results showed that the average operation time was 294.2 ± 36 minutes, average time for pancreaticojejunostomy was 35.9 ± 4.1 minutes, and average estimated blood loss was 204.2 ± 58.2 mL. Biochemical leakage occurred in 2 patients (16.7%), whereas no grade B or C POPF, 1 case (8.3%) had postoperative bleeding, and no death occurred within 30 days after the operation. Preliminary experience shows that the split pancreatic duct stent can effectively reduce the incidence of complications after LPD, especially grade B or C POPF.

Cytomegalovirus (CMV) is an opportunistic pathogen that exacerbates inflammatory bowel disease (IBD). There are no clear diagnostic criteria for CMV infection in IBD patients. The aim of this study was to evaluate the importance of the diagnosis of CMV infection with CMV-DNA polymerase chain reaction (PCR) in the colonic mucosa and the response to antiviral treatment. ⋯ Blood CMV-DNA PCR was found to be positive in a small group (33.3%, 10/30) of tissue CMV-DNA PCR-positive cases. immunohistochemistry tests were positive in only 5 of the 23 patients positive for CMV-DNA PCR in the colonic mucosa, and high remission (25/30, 83.3%) was detected with antiviral therapy. Recurrence of CMV colitis infection was observed in 9 of 25 patients who had remission with antiviral therapy. The tissue CMV-DNA PCR test was found to be more useful than blood CMV-DNA PCR and immunohistochemistry tests for diagnosing CMV colitis, and the tissue CMV-DNA PCR test enabled rapid and appropriate treatment.
