Purpose: To compare the outcomes of patients with and without a history of dacryocystitis that undergo dacryocystorhinostomy without systemic intra- and post-operative antibiotics.

Methods: A retrospective review was performed to identify all cases of patients that received surgery under this paradigm and had at least three months of follow up care. Key demographic and outcome data were captured, and a statistical analysis was performed via a dedicated software package (Microsoft Excel, Redmond, WA).

Purpose: To assess the impact of intravenous ketorolac (IVK) on self-reported pain scores, requirements for opioid analgesic and anti-emetic medications, and bleeding complications in the setting of levator advancement surgery METHODS:: A prospective randomized controlled trial was performed among adult patients undergoing levator advancement surgery. Pain scores were measured immediately after surgery, prior to discharge from the surgical facility, and on the first postoperative day. The requirements for postoperative analgesic and anti-emetic medications were recorded.

Periorbital nerve enlargement commonly indicates perineural invasion of malignancy or inflammatory conditions. This study reviews the role of supraorbital and infraorbital nerve biopsies in patients presenting with radiographic enlargement and to elucidate the surgical technique involved. A retrospective chart review (1997-2014) was performed at a single tertiary center.

Granuloma faciale is an eosinophilic dermatosis that typically presents as red-brown facial plaques of middle-aged white men, while eosinophilic angiocentric fibrosis is a histologically similar fibrotic condition affecting the respiratory mucosa. Both are very uncommon conditions and pose a therapeutic challenge. While a handful of reports have reported concurrent presentation, the authors present the first case of eyelid granuloma faciale with eosinophlilic angiocentric fibrosis.

Objective: To assess the effect of noise-cancelling headphones with or without music on patient pain and anxiety associated with routine, office-based transrectal ultrasound (TRUS)-guided prostate biopsy in a prospective randomized study.

Methods: Patients scheduled for prostate biopsy as a result of elevated prostate-specific antigen and/or abnormal digital rectal examination were prospectively enrolled and randomized into a control, noise-cancelling headphones, or music-headphones group. Patients completed pain and anxiety questionnaires and had their physiological parameters assessed before and after the procedure and compared across groups.

Background: Laparoscopic cryoablation (LCA) and percutaneous cryoablation (PCA) of small renal masses have gained popularity, but only limited data exist on the complication rates.

Objectives: In this study, we report on postoperative complications associated with LCA and PCA in a single tertiary center experience.

Design, Setting, And Participants: We conducted a retrospective review of electronic medical records for patients undergoing LCA or PCA between 2001 and 2008 at our institution.

The 3-D transrectal ultrasound (TRUS)-guided prostate biopsy system is a novel device that allows precise needle placement in a template fashion. We evaluate its utility for prostate cancer (PCa) detection. A retrospective analysis was performed evaluating 68 prospective patients at the Duke Prostate Center who underwent a prostate biopsy using a 3-D TRUS-guided system.

Purpose: We evaluated the clinical implication of persistent contrast enhancement demonstrated several months after laparoscopic renal cryoablation of a small renal mass.

Patients And Methods: Between September 2000 and May 2007, 30 patients underwent laparoscopic cryosurgery for an organ-confined renal tumor measuring View Article and Find Full Text PDF

Background And Purpose: We evaluated the effects of the first freeze-thaw cycle of cryoablation on Fuhrman grade, histology, and tumor architecture of small clear cell renal carcinomas and renal oncocytomas using an 18-gauge needle biopsy.

Patients And Methods: Between August 2006 and June 2007, 11 patients underwent cryoablation for 14 renal neoplasms. A laparoscopic approach was employed using third-generation argon/helium cryotechnology.

Laparoscopic cryoablation is a minimally invasive treatment that is currently used to treat small renal tumors. Despite its growing use and promising outcomes, complications can occur. We report the first clinical case of urothelial sloughing with obstruction after cryoablation of a small renal tumor in a solitary kidney.
