ABSTRACT
The differential diagnosis in anogenital ulcer-adenopathy syndrome in men who have sex with men (MSM) is becoming more complex, particularly with lymphogranuloma venereum and syphilis re-establishing endemicity among MSM. Sexual contact has been shown to transmit methicillin-resistant Staphylococcus aureus (MRSA), probably through intimate skin-to-skin contact. We present a case of MRSA genital ulceration and local lymphadenopathy in a man whose sexual partners are men, reporting high-risk sexual behaviour, highlighting the importance of also considering MRSA infection in these cases, and the potential for spread of MRSA infection in the MSM community.

We show that plane wave ultrasoft pseudopotential methods readily extend to the calculation of the structural properties of lanthanide and actinide containing compounds. This is demonstrated through a series of calculations performed on UO, UO2, UO3, U3O8, UC2, alpha-CeC2, CeB6, CeSe, CeO2, NdB6, TmOI, LaBi, LaTiO3, YbO, and elemental Lu.
ABSTRACT
In this Brief Report we show that the inhomogeneous density obtained from a density-functional theory of classical fluids in the canonical ensemble (CE), recently presented by White et al. [Phys. Rev. Lett. 84, 1220 (2000)], is equivalent to first order to the result of the series expansion of the CE inhomogeneous density introduced by Gonzalez et al. [Phys. Rev. Lett. 79, 2466 (1997)].
ABSTRACT
We present a density-functional approach for dealing with inhomogeneous fluids in the canonical ensemble. A general relation is proposed between the free-energy functionals in the canonical and the grand canonical ensembles. The minimization of the canonical-ensemble free-energy functional gives rise to Euler-Lagrange equations which involve averaged Ornstein-Zernike equations of second and third order. The theory is especially appropriate for systems with a small, fixed number of particles. As an example of application we obtain accurate results for the density profile of a hard-sphere fluid in a closed spherical cavity that contains only a few particles.
