Onychoscopic characteristics of Trichophyton rubrum and Trichophyton interdigitalis fungal infections: A multicentric study.

Background: Trichophyton rubrum and Trichophyton mentagrophytes variant interdigitalis are the most frequent etiologic agents of onychomycosis. Diagnosis of certainty requires mycological examination, which often results unfeasible.

Objectives: The aim of our study is to describe pathogen specific dermoscopic features, allowing a differential diagnosis without the need for cultural examination, in order to prescribe the most appropriate treatment anyway.

High-Grade Chondrosarcoma of the Proximal Phalanx: an Unusual Case of a Rare Entity.

Chondrosarcoma of the hand is a rare disease, but is one of the more common malignancies of the hand. Biopsies and imaging are a fundamental step in determining correct diagnosis, grading and selection for best treatment. We describe the case of a 77-year-old male complaining of a painless swelling in the proximal phalanx of the third ray of left hand.

Comparative effects of estradiol benzoate, the antiestrogen clomiphene citrate, and the progestin medroxyprogesterone acetate on kainic acid-induced seizures in male and female rats.

We have investigated the comparative effects of estradiol benzoate (EB), the antiestrogen clomiphene citrate (CC), and the progestin medroxyprogesterone acetate (MPA) on seizures induced by systemic injection of kainic acid (15 mg/kg i.p.) in male and female rats.
