We present new JHK photometry on the MKO-NIR system and JHK spectroscopy for a large sample of L and T dwarfs. Photometry has been obtained for 71 dwarfs and spectroscopy for 56. The sample comprises newly identified very red objects from the Sloan Digital Sky Survey (SDSS) and known dwarfs from the SDSS and the Two Micron All Sky Survey (2MASS). Spectral classification has been carried out using four previously defined indices (from Geballe et al. 2002, G02) that measure the strengths of the near infrared water and methane bands. We identify 9 new L8-9.5 dwarfs and 14 new T dwarfs from SDSS, including the latest yet found by SDSS, the T7 dwarf SDSS J175805.46+463311.9. We classify 2MASS J04151954−0935066 as T9, the latest and coolest dwarf found to date.We combine the new results with our previously published data to produce a sample of 59 L dwarfs and 42 T dwarfs with imaging data on a single photometric system -2and with uniform spectroscopic classification. We compare the near-infrared colors and absolute magnitudes of brown dwarfs near the L-T transition with predictions made by models of the distribution and evolution of photospheric condensates. There is some scatter in the G02 spectral indices for L dwarfs, suggesting that these indices are probing different levels of the atmosphere and are affected by the location of the condensate cloud layer. The near-infrared colors of the L dwarfs also show scatter within a given spectral type, which is likely due to variations in the altitudes, spatial distributions and thicknesses of the clouds. We have identified a small group of late L dwarfs that are relatively blue for their spectral type and that have enhanced FeH, H 2 O and K I absorption, possibly due to an unusually small amount of condensates.The scatter seen in the H − K color for late T dwarfs can be reproduced by models with a range in surface gravity. The variation is probably due to the effect on the K-band flux of pressure-induced H 2 opacity. The correlation of H − K color with gravity is supported by the observed strengths of the J-band K I doublet. Gravity is closely related to mass for field T dwarfs with ages > 10 8 yrs and the gravities implied by the H − K colors indicate that the T dwarfs in our sample have masses in the range 15 -75 M Jupiter . One of the SDSS dwarfs, SDSS J111010.01+011613.1, is possibly a very low mass object, with log g ∼ 4.2 -4.5 and mass ∼ 10 -15 M Jupiter .

A triage nurse-initiated protocol for early use of oral ondansetron and ORT in children with evidence of gastroenteritis is associated with increased and earlier use of ondansetron and ORT and decreased use of IV fluids and blood testing without lengthening ED stays or increasing rates of admission or unscheduled return to care.

From the standpoint of medicine as art for the prevention and cure of disease, the man who translates the hieroglyphics of science into the plain language of healing is certainly the most useful.-Sir William Osler I never write metropolis for seven cents because I can get the same price for city.

An E-CDS can effectively decrease CT scanning and increase use of ultrasound in children with suspected appendicitis in a community hospital ED. Electronic clinical decision support may be an effective method of disseminating pediatric best practices from a children's hospital to affiliated community EDs.
