Through our study, greater improvement of postoperative fecal continence after LAARP has not been shown. LAARP was at higher risk for mucosal prolapse and PUD. However, precise dissection of the urethral fistula could be performed after the introduction of urethroscopy.

Aims/Introduction:  The computed tomography (CT) value of the pancreas was examined across the range of glucose tolerance, and the relationships between pancreatic CT values and factors responsible for glucose intolerance were analyzed.Materials and Methods:  A total of 167 health‐check examinees were classified into normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and diabetes mellitus (DM) according to 75 g oral glucose tolerance test (OGTT). Pancreatic and hepatic CT values were estimated at decreasing stages of glucose tolerance. The association of CT values of the pancreas and the indices of glucose tolerance were analyzed.Results:  Insulinogenic index (II) was decreased from NGT through IGT to DM. Mean pancreatic CT value was decreased significantly from NGT through IGT to DM. Mean area under the curves of glucose (AUC‐G) was significantly associated with II and insulin sensitivity index (ISI) composite in univariate analysis. In multiple regression analysis, II was most strongly inversely correlated with mean AUC‐G, suggesting that II is the strongest determinant of glucose tolerance in Japanese. In addition, II was significantly associated with mean pancreatic CT value in univariate analysis. In multiple regression analysis, mean pancreatic CT value was strongly correlated with II.Conclusions:  Pancreatic CT values were significantly decreased from NGT through IGT to DM. II was the strongest determinant of glucose tolerance, and was significantly influenced by pancreatic CT values. Thus, pancreatic fat deposition might impair insulin secretion in the early stage of development of type 2 diabetes, before overt deterioration of glucose tolerance.

Background/Aim: Adiponectin, an adipocyte-derived protein, has been shown to exert antidiabetic, anti-inflammatory, and antiatherosclerotic effects. Although recent reports show an increase in the total adiponectin levels in chronic kidney disease patients and in patients with end-stage renal disease, the nature of biodegradation and renal involvement of adiponectin is largely unknown. We aimed at determining whether the high-molecular-weight (HMW) complex of adiponectin is associated with renal insufficiency in type 2 diabetic patients. Methods: A total of 179 type 2 diabetic patients were selected from among outpatients and divided into four groups according to their albumin-to-creatinine ratio: patients with normoalbuminuria (n = 86), patients with microalbuminuria (n = 44), patients with macroalbuminuria (n = 23), and patients on hemodialysis (n = 26). The serum HMW adiponectin was specifically assayed with a commercially available enzyme-linked immunosorbent assay kit. Results: The HMW adiponectin levels were higher in patients on hemodialysis (17.1 ± 8.2 µg/ml) and in those with macroalbuminuria (14.3 ± 8.7 µg/ml) than in patients with normoalbuminuria (7.2 ± 5.6 µg/ml) and microalbuminuria (10.8 ± 7.0 µg/ml). Univariate linear regression analysis showed that the HMW adiponectin concentrations correlated negatively with the estimated glomerular filtration rate in patients with normoalbuminuria, microalbuminuria, and macroalbuminuria (r = –0.42, p < 0.001). Multiple stepwise regression analysis disclosed that estimated glomerular filtration rate, pioglitazone therapy, gender differences, and systolic blood pressure were independently associated with HMW adiponectin levels (r = 0.56). Conclusions: The serum HMW adiponectin concentrations are higher in type 2 diabetic patients with nephropathy, and these levels are also associated with renal insufficiency.

A dipeptidyl peptidase (DPP)-4 inhibitor, commonly used to treat patients with type 2 diabetes, has caused concern because of immune system side effects. We report a 48-year-old woman with type 2 diabetes who was diagnosed with rheumatoid arthritis (RA) after continued polyarthritis and an increase in rheumatoid factor up to 86 IU/mL after three months of treatment with sitagliptin, a DPP-4 inhibitor. The shared epitope (SE)-containing human leukocyte antigen (HLA)-DRB1 alleles, which are important predisposing factors for RA, were positive. RA might have been triggered by sitagliptin due to a predisposing condition.
