Urology Patients and the Internet: Socioeconomic Status and Language Skills Significantly Impact Use.

Introduction: Patient Internet use and resources are likely multifactorial. We assess how socioeconomic factors and language skills affect Internet use by patients.

Methods: We prospectively surveyed 116 patients with a bilingual questionnaire before they underwent urological surgery from July to September 2013.

Mathematical and Ex Vivo Thermal Modeling for Renal Tumor Radiofrequency Ablation with Pyeloperfusion.

Background And Purpose: Radiofrequency ablation (RFA) is an effective technique for the treatment of patients with small renal tumors, although it is often limited to tumors at least 2 cm from the renal pelvis or ureter. Retrograde pyeloperfusion (PPF) of the pelvis with cold saline during RFA may protect the pelvis and ureter. We designed a mathematical and ex vivo model of RFA to investigate the effects of PPF.

Long-term oncologic outcomes following radiofrequency ablation with real-time temperature monitoring for T1a renal cell cancer.

Objective: Few studies report long-term follow-up of renal cancer treated by radiofrequency ablation (RFA), thus limiting the comparison of this modality to well-established long-term follow-up series of surgically resected renal masses. Herein, we report long-term oncologic outcomes of renal cancer treated with RFA in a single institution.

Methods And Materials: We retrospectively reviewed patients treated between November 2001 and October 2012 with laparoscopic-guided or computed tomography-guided RFA.

Some observations on the interdigitation of advances in medical science and mathematics.

The immense advancement of our understanding of disease processes has not been a uniform progression related to the passage of time. Advances have been made in "lurches" and "catches" since the advent of the written word. There has been a remarkable interdependency between such advances in medicine and advances in mathematics that has proved beneficial to both.

Broken heart syndrome: a risk of teenage rhinoplasty.

"Broken heart" syndrome is a rare phenomenon characterized by transient ballooning of the left ventricle and chronic heart failure, usually presenting in postmenopausal women. It is formally known as acute stress-induced cardiomyopathy and, although described in the cardiology literature, it has not been previously described in plastic surgery patients. It is thought to occur secondary to increased catecholamine levels.

Spontaneous coronary artery dissection.

Spontaneous coronary artery dissection (SCAD) is a rare and potentially deadly disease without a clear and universal treatment. Medical as well as mechanical interventions, including percutaneous and coronary bypass surgery, have been used. We present two dissimilar cases of SCAD that required markedly different treatments reflecting the variety in clinical presentation and outcome.
