Background:
The optimal surgical approach for managing multiple renal arteries in living donor kidney transplantation remains unclear. This study compared outcomes between separate anastomoses (SA) and pantaloon anastomosis (PA).
Methods:
A retrospective cohort study was conducted from November 2018 to August 2024. In total, 117 patients were included (SA, 67; PA, 50). The primary outcome was arterial complications. Secondary outcomes included renal function, graft and patient survival at 1 year, and intraoperative variables. Statistical analyses utilized the t-test, the Mann-Whitney U-test, and Kaplan-Meier survival curves.
Results:
The mean warm ischemia time was similar between groups (105.48±35.64 vs.103.92±33.51 min; P=0.811). Cold ischemia time was also comparable (75.90±14.36 vs.80.68±17.85 min; P=0.111). However, anastomosis time was significantly longer in the SA group (39.00 [35.00–43.00] min) compared with the PA group (34.00 [28.50–39.50] min; P<0.001). The immediate postoperative creatinine reduction was slightly greater in the SA group (46.83%±20.68% vs. 39.78%±19.04%; P=0.090). Vascular complications requiring re-exploration were infrequent in both groups (1.5% vs. 2.0%). At 1 year posttransplant, creatinine levels were comparable between the SA (1.20 [0.95–1.45] mg/dL) and PA (1.20 [1.05–1.35] mg/dL) groups (P=0.337). Regression analysis confirmed that postoperative creatinine levels were independently associated with SA (P=0.006). Graft survival was similarly high (97% vs. 98%), as was patient survival (100% vs. 96%).
Conclusions
Both anastomosis techniques are safe and effective for transplanting kidneys with anatomical anomalies. SA offers surgical efficiency and provides superior early renal recovery.

Objective:
This study aimed to compare the predicted and achieved labiolingual inclinations of the maxillary central incisors in adult Class II division 2 malocclusions treated with clear aligners using Power Ridges® and composite attachments.
Methods:
This retrospective study included 24 patients (mean age, 26.5 ± 3.3 years). The patients had Class II division 2 malocclusion and were treated with non-extraction with Invisalign® clear aligners with either Power Ridges® or composite attachments to enhance the predictability of required change in labiolingual inclination for the maxillary central incisors.Before treatment, treatment prediction and final digital models were exported as stereolithography files and superimposed using the eModel 9.0 “Compare” software. The predicted and achieved labiolingual incisor inclinations were compared.
Results:
The mean accuracies of the achieved inclination of the central incisors were 68.3% in the Power Ridges® group and 71.6% in the attachments group. No statistically significant differences in predictability were found between the groups (P > 0.05). A low positive correlation was observed between the predicted inclination change and the average absolute difference between the predicted and achieved inclinations (r = 0.19).
Conclusions
Predicted labiolingual inclination is not fully achieved with clear aligners in both the Power Ridges® and attachment groups. Clinicians must take measures to counteract this limitation, specifically in Class II division 2 cases.

Diaphragmatic fibromatosis is an exceptionally rare condition, with only 2 previously reported cases in the literature. We present the case of a 23-year-old woman with a left hypochondrial swelling measuring 19×18×13 cm on computed tomography. An endoscopic ultrasound-guided biopsy indicated low-grade papillary proliferation. Surgical exploration revealed a large mass originating from the left hemidiaphragm. Complete excision of the mass and reconstruction of the diaphragm with double-layer mesh were performed.Microscopic examination of the mass revealed a bland-looking spindle cell proliferation.Immunohistochemical staining showed a positive nuclear reaction in tumor cells for β-catenin, a focal positive reaction for SMA, and negative reactions for S100, CD34, and desmin.Diaphragmatic fibromatosis is an extremely rare tumor for which complete excision and reconstruction of the diaphragm is the best suggested modality of treatment.

This study is aimed to provide an insight into the types of treatment carried out by postgraduate students in the past 10 years. A retrospective study was carried out between November 2019 and February 2020 by deriving data from postgraduate students’ clinical logbooks of three different cohorts of Master of Clinical Dentistry (Restorative Dentistry in Conservative Dentistry) in 2010, 2013 and 2016. This retrospective data was systematically extracted from the records and tabulated categorically using an Excel spreadsheet (Microsoft Office Excel 2019). A descriptive analysis was carried out to further evaluate the results. Overall, the types of treatment carried out in the field of endodontics and fixed prosthodontics has changed in the past 10 years. An increasing trend is seen in the placement of all ceramic crowns and primary root canal treatment procedures, while a decreasing pattern is evident for secondary root canal procedures and placement of dental bridges.
