Parathyroidectomy in secondary hyperparathyroidism: Is there an optimal operative management?

BACKGROUND Subtotal parathyroidectomy (SPTX) and total PTX with autotransplantation (TPTX + AT) are both accepted operations for secondary hyperparathyroidism (2HPT). Studies have shown the 2 procedures to have similar rates of recurrent or persistent HPT (0% to 10%). The majority of these reports are small case series and despite apparently similar outcomes; the optimal operative management fo...

Is there an optimal management for localized prostate cancer?

Widespread screening with prostate-specific antigen (PSA) has led to a significant increase in the detection of early stage, clinically localized prostate cancer (CaP). Various treatment options for localized CaP are discussed in this review article including active surveillance, radical prostatectomy, radiation therapy, and cryotherapy. The paucity of high-level evidence adds a considerable am...

IP Restoration vs. WDM Protection: Is There an Optimal Choice?

The exponentially growing number of Internet users armed with emerging multimedia Internet applications is continuously thirsty for more network capacity. Wavelengthdivision multiplexing networks that directly support IP — the so-called IP over WDM architecture — have the appropriate characteristics to quench this bandwidth thirst. As everyday life increasingly relies on telecommunication servi...

Is there an optimal basis to maximise optical information transfer?

We establish the concept of the density of the optical degrees of freedom that may be applied to any photonics based system. As a key example of this versatile approach we explore information transfer using optical communication. We demonstrate both experimentally, theoretically and numerically that the use of a basis set with fields containing optical vortices does not increase the telecommuni...
