The least amount of soluble aggregates and subvisible particles were detected in the Bis-mAb formulations with the highest colloidal stability and refoldability from urea. We suggest that the optimization of these two features is crucial for obtaining physically stable formulations of Bis-mAb. OBJECTIVE To explore the current practice patterns for the management of renal cysts internationally among pediatric urologists and nephrologists. MATERIALS AND METHODS A survey composed of 21 questions and 4 clinical scenarios was distributed to pediatric urologists and nephrologists. Survey questions evaluated optimal imaging modality, management, and follow-up period. Inter-specialty comparisons were made using chi-square analysis where appropriate. RESULTS A total of 183 respondents completed the survey (128 pediatric urologists, 37 pediatric nephrologists, and 19 other specialists). Most (57%) respondents agreed or strongly agreed with using an ultrasound based Bosniak classification to categorize renal cysts in children. The most commonly used follow-up intervals were 6-12 months for pediatric urologists and 1-2 years for pediatric nephrologists. Symptomatic mass effect (80.9%), gross hematuria (79.2%), or family history were the most common reasons for escalating surveillance. Pediatric nephrologists were more likely to increase follow-up with development of bilateral simple renal cysts (p=0.008) or chronic kidney disease (p=0.027) when compared to pediatric urologists. Laparoscopic marsupialization (39.4%) was the most common treatment for a simple renal cyst in a symptomatic child. Modified Bosniak III cysts had more heterogeneity in treatment based on the physician responses. CONCLUSION There is currently no consensus on the optimal protocol for the surveillance, imaging, or treatment of renal cysts in children. Most respondents agree that using an ultrasound based Bosniak classification is reasonable. A call to action is therefore necessary for the development of registries and guidelines on the management of pediatric renal cysts and their associated malignancies. Cutaneous larva migrans (CLM) also termed as " creeping eruption", is a parasitic infestation produced by burrowing of the larva of Ancylostoma braziliense. The larva enters intact or abraded skin following exposure with soil contaminated with faeces. Solitary tracts involving feet, hands, buttocks, and genitalia are usually encountered. Although CLM is an endemic tropical disease; in this era of global migration, physicians worldwide should promptly diagnose and treat the condition. OBJECTIVE To assess the effect of a sharp increase in estrogen levels on overactive bladder (OAB) symptoms among women undergoing ovulation induction. METHODS 100 consecutive women (mean age 36.9±5.2 years) who underwent IVF treatments, were prospectively enrolled. Three validated questionnaires on urinary urgency (USIQ), urinary incontinence (MESA), and lower urinary tract symptoms (BFLUTS-SF) were used to evaluate patient's OAB symptoms before ovulation induction (low estradiol level) and prior to ovum pickup (peak estradiol level). RESULTS Of the 100 women, 49 reported OAB symptoms prior to ovulation induction (mean USIQ severity score 33) and 51 women were asymptomatic. Of the 49 symptomatic women, 44 (90%) remained symptomatic (mean USIQ severity score 34) and five women became asymptomatic through ovulation induction. Of the 51 asymptomatic women, 24 (47%) developed de novo OAB symptoms, while 27 women (53%) remained asymptomatic through ovulation induction. The mean peak estradiol level was significantly higher among women who remained asymptomatic in comparison to women with de novo OAB symptoms (2069 versus 1372 pg/ml; respectively). Moreover, in most (63%) women who remained asymptomatic, peak estradiol levels were higher than 1500 pg/ml, whereas in most (67%) women who became symptomatic, peak estradiol levels were lower than 1500 pg/ml. CONCLUSION A higher estradiol level appears to have a protective effect against the development of OAB symptoms during ovulation induction. Further, in most (63%) women who remained asymptomatic, peak estradiol levels were higher than 1500 pg/ml. This finding may suggest a threshold for estradiol activity in the lower urinary tract. U0126 MEK inhibitor OBJECTIVES To describe patients presenting with urologic complications following pelvic radiation therapy and estimate the financial costs incurred in their treatment. PATIENTS AND METHODS In the year ending June 2018, all urology admissions at Royal Newcastle Centre were reviewed for diagnostic codes pertaining to urethral or ureteric strictures, cystitis and haematuria. Presentations were complications following radiotherapy if a diagnosis of radiation cystitis or stricture was recorded, and there was relevant prior radiotherapy. The Independent Hospital Pricing Authority's (IHPA) National Weighted Activity Unit (NWAU) 2018 calculators, admission data and the National Efficient Price (NEP) were used to estimate costs of care. HNELHD HREC granted ethics approval (AU201808-10). RESULTS Complications following radiotherapy accounted for 65 admissions in 53 discrete patients, accounting for 206 bed days and 3.7% of the 1748 total urology admissions in one year. The majority (86%) of admissions had at least one operation. Mean time since radiotherapy was 7 years (range 1-30). Mean number of operations related to complications following radiotherapy was 3 (range 0-11).  Readmissions were more frequent (mean 1.9 admissions/year) than other urology inpatients (mean 1.3 admissions/year, P less then 0.001). Mean NWAU18 value was 4.12 (range 2-8.3). Admission and procedure costs were AUD $1,346,700, secondary malignancies were $9,000 and emergency department costs were $45,864 for a combined total of $1,401,591. CONCLUSIONS Patients requiring urological admission with complications following radiotherapy use more resources, stay for longer, have more operations and return more frequently than other urology patients. Conservative estimates of cost $25,900 per patient in the study year alone. The proposed image reports the case of penile calciphylaxis. Calciphylaxis is a rare obliterative small vessel vasculopathy associated with diabetes mellitus, end-stage renal disease. Penile involvement is even rarer with only 50 cases reported, and agreement on appropriate diagnosis and management is unclear. This rarity exposes, as in our situation, to misdiagnosis, with possible iatrogeny (dermocorticoides in the case of balanitis). As the biopsy of the glans is not recommended, the clinical diagnosis is essential. Diffuse calcifications appearance on the reported ultrasound could support the diagnosis.
