Oncologic control and predictors of urologic reconstruction after Mohs micrographic surgery for low-risk penile malignancy.

Purpose: Mohs micrographic surgery (MMS) is a low-risk penile cancer management option. However, contemporary patients' short-term oncologic control and preoperative characteristics predicting reconstruction needs are undefined. This study assesses MMS's oncologic efficacy for low-risk penile cancer and identifies baseline predictors of post-resection reconstruction referral.

Diminished Short-Term Efficacy of Reduced-Dose Induction BCG in the Treatment of Non-Muscle Invasive Bladder Cancer.

The ongoing Bacillus Calmette-Guérin (BCG) shortage has created challenges for the treatment of non-muscle invasive bladder cancer (NMIBCa). Our objective was to evaluate the efficacy of reduced-dose induction BCG (RD-iBCG) compared to full-dose induction BCG (FD-iBCG) regarding recurrence rates. We hypothesized that patients receiving RD-iBCG may recur at a higher rate compared to those who received FD-iBCG therapy.

Prognostic significance of sarcomatoid features in metastatic renal cell carcinoma treated with cytoreductive nephrectomy and targeted therapy.

Introduction: The presence of sarcomatoid features in localized renal cell carcinoma (RCC) is associated with worse outcomes. We sought to use a national database to evaluate the outcomes and prognosis of metastatic RCC (mRCC) with sarcomatoid features treated with cytoreductive nephrectomy (CN) and targeted therapy (TT).

Methods: The National Cancer Database (2010-2013) was used to identify patients with mRCC at diagnosis.

Spontaneous rupture of a bladder diverticulum with delayed open surgical repair.

Spontaneous rupture of a bladder diverticulum is a rare entity typically associated with tissue weakness, bladder outlet obstruction, increased intra-abdominal pressure, or inflammation. Diagnosis is most often achieved via cystogram with a reported role for pelvic ultrasound. Extraperitoneal ruptures are typically treated with catheterization and antibiosis while intraperitoneal ruptures are most frequently treated with immediate surgical intervention.

Interactions of an Anti-Sickling Drug with Hemoglobin in Red Blood Cells from a Patient with Sickle Cell Anemia.

The pathophysiology associated with sickle cell disease (SCD) includes hemolytic anemia, vaso-occlusive events, and ultimately end organ damage set off by the polymerization of deoxygenated hemoglobin S (HbS) into long fibers and sickling of red blood cells (RBCs). One approach toward mitigating HbS polymerization is to pharmacologically stabilize the oxygenated (R) conformation of HbS and thereby reduce sickling frequency and SCD pathology. GBT440 is an α-subunit-specific modifying agent that has recently been reported to increase HbS oxygen binding affinity and consequently delay in vitro polymerization.
