Acupuncture for Analgesia During Transurethral Resection of Bladder Tumor.

Background: Acupuncture has been widely studied, and theories regarding its analgesic mechanism of action have been proposed. It has been used for procedural analgesia; however, no reports of its use in urologic surgery have been reported. In this case report, we demonstrate how acupuncture can be used as an alternative to general anesthesia for transurethral resection of bladder tumor (TURBT). This may serve as an attractive option for bladder cancer patients with medical comorbidities, which predispose them to high risk for general anesthesia. Case Presentation: A 65-year-old Caucasian female with toxicant-induced loss of tolerance (TILT) was found to have a bladder mass. TURBT was discussed, and in light of her TILT syndrome, she elected to undergo the procedure with acupuncture in lieu of general anesthesia for fear of an adverse reaction. Acupuncture was performed by a trained practitioner with therapeutic needles placed in the ears, hands, abdomen, and lower extremities bilaterally. She was subsequently taken to the operating room where we performed a TURBT of a bladder tumor overlying the left ureteral orifice. The procedure was generally well tolerated and the patient experienced mild pain. There were no perioperative complications. The tumor was estimated to be 3 cm in largest diameter, and a total of 8 g of aggregate tissue was sent to our pathologists. Pathology analysis demonstrated adequate resection with detrusor muscle present in the sample. The bladder tumor was low-grade papillary urothelial cell carcinoma (Stage Ta). She has had tumor recurrence and has undergone repeat TURBT, but to date, she is 22 months free of bladder cancer. Conclusion: In this case report, we demonstrate that acupuncture is a safe and effective alternative to general anesthesia for patients undergoing TURBT. Since tobacco use is prevalent among bladder cancer patients, many of these individuals have associated medical comorbidities, which predispose them to high risk with general anesthesia. Therefore, acupuncture may serve as an attractive alternative for certain patients in this population.

Novel Selective Agents for the Degradation of Androgen Receptor Variants to Treat Castration-Resistant Prostate Cancer.

Androgen receptor (AR) mediates the growth of prostate cancer throughout its course of development, including in abnormal splice variants (AR-SV)-driven advanced stage castration-resistant disease. AR stabilization by androgens makes it distinct from other steroid receptors, which are typically ubiquitinated and degraded by proteasomes after ligand binding. Thus, targeting AR in advanced prostate cancer requires the development of agents that can sustainably degrade variant isoforms for effective therapy. Here we report the discovery and characterization of potent selective AR degraders (SARD) that markedly reduce the activity of wild-type and splice variant isoforms of AR at submicromolar doses. Three SARDs (UT-69, UT-155, and (R)-UT-155) bind the amino-terminal transcriptional activation domain AF-1, which has not been targeted for degradation previously, with two of these SARD (UT-69 and UT-155) also binding the carboxy-terminal ligand binding domain. Despite different mechanisms of action, all three SARDs degraded wild-type AR and inhibited AR function, exhibiting greater inhibitory potency than the approved AR antagonists. Collectively, our results introduce a new candidate class of next-generation therapeutics to manage advanced prostate cancer. Cancer Res; 77(22); 6282-98. ©2017 AACR.

A Rare Inherited 15q11.2-q13.1 Interstitial Duplication with Maternal Somatic Mosaicism, Renal Carcinoma, and Autism.

Chromosome 15q11-q13.1 duplication is a common copy number variant associated with autism spectrum disorder (ASD). Most cases are de novo, maternal in origin and fully penetrant for ASD. Here, we describe a unique family with an interstitial 15q11.2-q13.1 maternal duplication and the presence of somatic mosaicism in the mother. She is typically functioning, but formal autism testing showed mild ASD. She had several congenital anomalies, and she is the first 15q Duplication case reported in the literature to develop unilateral renal carcinoma. Her two affected children share some of these clinical characteristics, and have severe ASD. Several tissues in the mother, including blood, skin, a kidney tumor, and normal kidney margin tissues were studied for the presence of the 15q11-q13.1 duplication. We show the mother has somatic mosaicism for the duplication in several tissues to varying degrees. A growth competition assay in two types of stem cells from duplication 15q individuals was also performed. Our results suggest that the presence of this interstitial duplication 15q chromosome may confer a previously unknown growth advantage in this particular individual, but not in the general interstitial duplication 15q population.

National trends in hospitalization from indwelling urinary catheter complications, 2001-2010.

PURPOSE: The purpose of this study is to investigate national trends in hospitalization from indwelling urinary catheters complications from 2001 to 2010. MATERIALS AND METHODS: The Healthcare Utilization Project Nationwide Inpatient Sample database was analyzed for this study. We examine hospitalization rates, patient demographics, hospital stays, insurance provider, hospital type, geographic location, and septicemia rates of patients hospitalized for indwelling urinary catheter complications from 2001 to 2010. RESULTS: Hospitalization from indwelling urinary catheters almost quadrupled from 11,742 in 2001 to 40,429 in 2010. The increases have been due to patients who are older and predominantly male compared to all hospitalization. The "national bill" increased from $213 million to $1.3 billion (a factor of 6) after adjusting for inflation. Most patients had urinary tract infections, 77 % in 2001 and 87 % in 2010. Septicemia in indwelling urinary catheter hospitalization patients has increased from 21 % in 2001 to 40 % in 2010. In 2010, secondary diseases associated with hospitalization due to indwelling urinary catheters included urinary tract infections (86.5 %), adverse effects of medical care (61.9 %), bacterial infection (48.6 %), and septicemia (40.3 %). CONCLUSIONS: Hospitalization due to indwelling urinary catheter complications has almost quadrupled from 11,742 in 2001 to 40,429 in 2010, and the majority of patients had urinary tract infections. Septicemia is of particular concern since rates have almost doubled (from 21 to 40 % over the period) in these patients. The specific medical indication for urinary catheters used postoperatively should be scrutinized, and the duration of placement should be minimized to reduce future complication rates.
