BABA RT for Graves' disease showed comparable surgical completeness and complications to conventional OT. BABA RT can be recommended as an alternative surgical option for patients with Graves' disease who are concerned about cosmesis.
We investigated whether a combination of recently introduced methods, total demineralization and ion-exchange columns, would increase DNA recovery from old bone. Ten bone samples taken after a burial period of approximately 60 years were used in this study. Bone powder was digested using total or incomplete demineralization. DNA was extracted by the standard organic method. The DNA extract was purified with ion-exchange columns or QIAquick spin columns. The efficiency of different DNA extraction methods was compared in terms of DNA concentration, inhibitors generated by real-time PCR, and conventional STR typing results. The mean DNA concentration using the total demineralization method is approximately 3 times higher than that using the incomplete demineralization method. For DNA purification, the method using QIAquick spin columns appeared to yield approximately double the DNA than the method using ion-exchange columns. Furthermore, 2 out of 10 samples showed higher levels of inhibition with C(T) values of IPC > or =30 cycles when using only ion-exchange columns. In STR results, total demineralization yielded more locus profiles by 4.2 loci than incomplete demineralization, and QIAquick spin columns also yielded more locus profiles by 3.5 loci than ion-exchange columns. Total demineralization of bone powder significantly increased DNA yield and improved STR typing results. However, the use of ion-exchange columns was not efficient when compared with the method using QIAquick spin columns. It is suggested that the combination of total demineralization and QIAquick spin columns lead to greatly improved STR typing results.
PurposeThe aim of this study was to describe the surgical clip-related complications that can occur after open retropubic prostatectomy (RRP), pure laparoscopic prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RALP).Materials and MethodsA database of 641 patients who underwent RRP (n=439), LRP (n=49), and RALP (n=153) at our institution between January 2006 and April 2009 was reviewed to identify patients with complications related to the use of surgical clips. The median follow-up time for the entire cohort was 19.0 months (range, 1-42 months).ResultsOf the 641 patients, 25 (5.7%), 1 (2.0%), and 2 (1.3%) had a bladder neck contracture after RRP, LRP, and RALP, respectively. Two RRP patients had a bladder stone. In total, 6 patients had surgical clip-related complications. Metal clip migration was associated with 2 (8%) of the 25 RRP cases of bladder neck contracture and both (100%) of the RRP cases of bladder stone. Moreover, both (100%) of the RALP cases of bladder neck contractures were associated with Hem-o-lok clip migration into the anastomotic site.ConclusionsSurgical clips are prone to migration and may cause, or significantly contribute to, bladder neck contracture or the formation of bladder stones after radical prostatectomy. These findings also suggest that because the incidence of bladder neck contracture after RALP is low, the migration of Hem-o-lok clips should be suspected when voiding difficulty occurs after RALP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
