The re-recurrence rate after surgery for recurrent rectal prolapse is high, even at a relatively short follow-up interval. Our data suggest that abdominal repair of recurrent rectal prolapse should be undertaken if the patient's risk profile permits this approach.

Almost half of the respondents reported having sexual dysfunction. Although poor pouch function was not identified as an important predictor of sexual dysfunction in this series, larger studies may be required to identify associated prognostic factors clearly.

Human T-cell leukemia virus type-1 (HTLV-1) is the etiological agent of adult T-cell leukemia (ATL), and leukemic cells always carry the proviral genome monoclonally integrated into their host genomes at the same sequence site, designated as the monoclonal integration. Using Southern blot hybridization (SBH) and sequenced tagged site polymerase chain reaction assays, we examined the proviral status in 558 clinical specimens from 350 patients who are suspected to have ATL. A total of 321 specimens (57.5%) from 241 patients showed positive results for the monoclonal integration according to SBH, using EcoR1 and Pst1. The 241 patients consisted of 136 patients (56.4%) with the complete provirus (C-type), 62 patients (25.7%) with a defective provirus (D-type), and 43 patients (17.8%) with multibands (M-type). The incidence of the D- and M-types were in the order of smoldering, chronic, and acute subtypes of ATL, suggesting that such an aberrant proviral status is generated on the way to multistep carcinogenesis and is subsequently clinically important for the malignant behavior of the disease. Moreover, our data showed that the partial deletion of the proviral genome is initiated first at the site of the gag region and spreads into the sites of the pol and env regions, whereas the long terminal repeats and pX regions are almost always conserved. These results suggest that analysis of the proviral status provides useful diagnostic and virologic-oncological information about ATL and HTLV-1 pathology, especially the important role of pX gene in tumorigenesis.

Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC.
