Abstract Introduction: Malignant mesothelioma involving the tunica vaginalis is an extremely rare tumor.
Case: We describe a case of a 39-year-old man who initially presented with discomfort in the left testis and underwent resection of a hydrocele in the left testis. A pathology examination of a frozen section of a lesion on the tunica identified the lesion as mesothelioma, which was confirmed by a second pathology examination. No metastatic disease was found. The patient subsequently underwent a left radical orchiectomy and a partial scrotectomy, and has been disease free for 7 years.
Discussion: The first case of malignant More >

Abstract We report a case of a 19-year-old female who presented with right flank pain and microscopic hematuria.Three years earlier, she sustained a stab wound to the right flank and was managed conservatively. After being diagnosed with an enhancing renal mass using computed tomography (CT) scan, duplex ultrasound and angiography were performed revealing an intrarenal pseudoaneurysm. Endovascular coils were successfully employed to selectively embolize the pseudoaneurysm. More >

Abstract Prostatic abscess is a rare and potentially life-threatening disease when left untreated. We report the first case of a man who developed a prostatic abscess as a long-term complication of cryoablation for primary prostate cancer. Timely diagnosis with non-contrast computed tomography (CT) scan, retrograde CT cystogram to ensure no bladder involvement, percutaneous drainage under CT-guidance, and antibiotic treatment sensitive to the causative organism were crucial for prompt recovery.

Abstract The use of radiation therapy in the radical treatment of prostate cancer can lead to potential acute and long-term toxicity and health-related quality-of-life (HRQoL) changes. Ongoing investigation into dose-escalation, dose-per-fraction escalation, new radiation treatment technology/ paradigms, and novel systemic therapy may have either positive and/or negative effects on normal tissue toxicity/ HRQoL. Herein, common toxicity scales and HRQoL instruments that attempt to describe the deleterious effects of prostate radiation therapy are reviewed. More >

Abstract Stuttering priapism is a clinical phenomenon that occurs commonly in certain patient populations, including sickle cell anemia and other hematologic dyscrasias. Although the mechanism is still not completely understood, treatment is focused on prevention of recurrence in the outpatient setting, and immediate detumescence and minimizing corporal fibrosis in the acute setting. We present a case of stuttering priapism in a 44 year-old male with hereditary spherocytosis and discuss the pathophysiology and clinical management of this entity. More >

Abstract Introduction: To date, no study has compared postoperative pain and requirement for pain medications in open versus robot-assisted radical cystectomy. Patient reported pain and opiate use were reviewed retrospectively using prospectively collected data from postoperative day one to day of discharge.
Materials and methods: Twenty consecutive robot-assisted radical cystectomy patients were compared to the prior 20 patients who underwent open radical cystectomy. Data was collected prospectively to determine opiate requirements and pain scores in each group. Daily opiate use was converted to morphine sulfate equivalents (MSE) to facilitate comparison. A Likert pain perception scale was used to… More >

Abstract Pediatric renal cell carcinoma (RCC) is relatively rare and appears to comprise a group of tumors distinct from RCCs typically seen in adults. Recently described tumors show an association with neuroblastoma or specific chromosomal translocations. Only rarely have other childhood cancers been associated with pediatric RCC. We present two cases of pediatric RCC following treatment of other childhood malignancies not previously described, supratentorial primitive neuroectodermal tumor and acute lymphoblastic leukemia, and review the literature on pediatric RCC. As the RCCs were discovered as incidental radiologic findings, we emphasize the importance of close follow-up (including imaging) More >

Abstract Introduction: A modified suture technique for urethro-vesical anastomosis during radical retropubic prostatectomy was developed and utilized in a cohort of patients. Comparative analysis of postoperative outcome was performed with a previous group of patients who had an anastomosis with the conventional technique.
Material and methods: A consecutive group of patients who underwent radical retropubic prostatectomy in our department with the diagnosis of localized prostate cancer was included in this retrospective study. Urethro-vesical anastomosis was performed either with the new or conventional method (CM). Outcome data of these two different patient sets were compared.
Results: One-hundred and one… More >

Abstract The objective of this work was to determine the effect of deficiency versus toxicity of N on biosynthesis of proline in fruits of green bean plants (Phaseolus vulgaris L. cv. Strike). Nitrogen was applied to the nutritive solution in the form of NH₄NO₃ at 1.5 mM (N1), 3.0 mM (N2), 6.0 mM (N3, optimal level), 12.0 mM (N4), 18.0 mM (N5), and 24.0 mM (N6). Nitrogen deficiency (N1 and N2) was characterized by having lower proline accumulation in pods and seeds, mainly because proline degradation was stimulated by the enzyme proline dehydrogenase. On the other hand, N More >
