INTRODUCTION Congenital midline lingual lesions are rare complex problems in the pediatric population, causing issues ranging from feeding difficulty to life-threatening airway obstruction. Treatment options generally include excision or marsupialization. Due to the size and configuration of the neonatal pharynx, resections of tongue base masses present a unique surgical challenge. The method o...

short): Hollow-core Optical Fiber Gas LASer (HOFGLAS) have been created, and explored in pulsed mode with C2H2 and HCN gas inside the hollow core of a kagome structured photonic crystal fiber, and nearideal efficiencies were realized for wavelengths near 1.5 μm (pump, 1 ns-pulses) and 3 μm (lasing). Improved fiber loss is realized near 3 μm to <1 dB/m. In addition, a pulsed CO2 waveguide (silve...

Hemangioma of the renal calyx is a rare disease, which is difficult to diagnose and an even greater challenge to treat. We report the use of the new-generation flexible ureteroscope, in the management of a 37-year-old Asian male with a lower pole renal calyx hemangioma, which was previously inaccessible.

The experimental and theoretical adiabatic ionization energies (IEs) of the rhodium-holmium bimetallic clusters RhHo(2)O(n) (n=0-2) have been determined using photoionization efficiency spectroscopy and density functional theory (DFT) calculations. Both sets of data show the IE of RhHo(2)O to be significantly lower than the values for RhHo(2) and RhHo(2)O(2), which are found to be similar. This...
