Paradoxical air embolism during percutaneous nephrolithotomy due to patent foramen ovale: Case report.

Paradoxical air embolism is a very rare complication associated with percutaneous nephrolithotomy (PCNL). Incidence may be higher if patients also suffer from a septal heart defect. We report the case of a 76-year old male who presented for PCNL treatment of a right kidney lower calyceal calculus.

Primary cutaneous mucinous carcinoma of the penis.

Primary cutaneous mucinous carcinoma (PCMC) is a rare, slow growing, malignant neoplasm arising from the sweat glands. Lesions are most commonly seen on the head and neck, and frequently mistaken for metastases from more common primary sites, such as the breast, gastrointestinal tract, lung, ovary, or prostate. We present what we believe is the first reported case of PCMC involving the penis.

Penile necrosis requiring penectomy complicating recto-urethral fistula post prostate cancer external beam radiation and brachytherapy.

Radiation therapy is a well-recognized treatment for unfavourable risk localized prostate cancer. Radiation induced recto-urethral fistulae are known rare complications particularly from brachytherapy. We report a case of a recto-urethral fistula 7 years post-external beam radiation and I-125 brachytherapy, which was complicated by a severe polymicrobial soft tissue infection.

Atrophic upper pole of a duplex collecting system masquerading as suprarenal mass: a case study and literature review.

The growing use of maternal fetal ultrasound is leading to the discovery of an increasing number of suprarenal masses. Our experience with a cystic suprarenal mass detected on antenatal ultrasound is described. Location and radiographic features could not rule out the possibility of a cystic neuroblastoma; therefore, surgical resection of the mass was performed.

Urachal-sigmoid fistula associated with diverticular disease.

Background: Urachal anomalies rarely present in adulthood. We report the second known case of urachal-sigmoid fistula associated with diverticular disease.

Method: We performed a case report and literature review.

Management of ischemic priapism with high-dose intracavernosal phenylephrine: from bench to bedside.

Introduction: Ischemic priapism is associated with cavernosal acidosis, which decreases the efficacy of adrenergic agonists. We determined the effect of acidosis on ligand dissociation from adrenergic receptors and assessed the efficacy of high-dose phenylephrine in treating patients with acute ischemic priapism.

Methods: Dissociation rates of [3H]prazosin were determined at pH 7.

Xanthogranulomatous pyelonephritis in a 1-year old boy.

Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic inflammatory lesion of the kidney associated with both chronic infection and obstruction. Most common in middle-aged females, it is important to recognize in children because it may be confused with childhood renal malignancies particularly Wilms' tumor. We report a case of a 1-year old male with antenatally detected and postnatally confirmed hydronephrosis.

Laparoscopic resection of a juxta-adrenal schwannoma.

A seven centimeter supra-renal mass was discovered in a 62-year old patient who presented with gross hematuria and a superficial bladder tumor. The supra-renal mass was resected laparoscopically and the final pathology revealed a benign schwannoma. The epidemiology, diagnostic features and treatment options for this rare peripheral nerve sheath tumor are reviewed.

Incorrect biochemistry complicates prostate cancer management.

A man with a prostate specific antigen (PSA) of 6.1 ng/mL, a clinical stage T2b prostate nodule and biopsies that showed Gleason sum 6 adenocarcinoma of the prostate underwent a radical prostatectomy. The final pathology showed organ-confined disease.
