Lucio's leprosy: a clinical and therapeutic challenge.

Leprosy has been a challenge in different areas of medicine; in underdeveloped countries it remains a public health problem, in which the social and economic problems facilitate the disease persistence. The diagnosis and consequently the treatment are delayed due to the clinical polymorphism of leprosy, which especially at the beginning the manifestations are not as evident, as is the case of diffuse lepromatous leprosy. This favors the disabilities and the development of the reaction episodes.

Estrous cycle phase and gonadal hormones influence conditioned fear extinction.

Gonadal hormones modulate fear acquisition, but less is known about the influence of gonadal hormones on fear extinction. We assessed sex differences and the influence of gonadal hormone fluctuations and exogenous manipulations of estrogen and progesterone on acquisition, extinction learning and extinction recall in a 3 day auditory fear conditioning and extinction protocol. Experiments were conducted on males and naturally cycling female rats.

Intensity of FDG uptake is not everything: synchronous liposarcoma and fibrous dysplasia in the same patient on FDG PET-CT imaging.

A growing number of studies have demonstrated the usefulness of FDG PET-CT in the preoperative assessment of soft tissue sarcomas. We report a case of a patient with a known low-grade liposarcoma demonstrating only mild hypermetabolism on a FDG PET-CT study. An incidental osseous lesion was found in the distal tibia of the same extremity during the initial workup.
