[Suspicion of systemic diseases through nails abnormalities].

Nails are protective, thin, horny growth at the end of fingers and toes. Abnormalities of the fingernails and toenails can provide both subtle and obvious clues to common medical problems or severe systemic diseases. Inheritance, minor injuries, common habits, the use of cosmetics and a variety of infections account for many changes in the appearance of nails. Awareness of normal nail variants, abnormalities and their disease associations will be beneficial to detect systemic diseases.

Leeches are flattened annelids or segmented worms that live in still, warm waters of the pond or in land. They feed of blood or body fluids. Medicinal leeches (Hirudo medicinalis) have been used in medicine for thousands of years to treat a wide range of ailments. Nowadays, leeches are used successfully for only a few conditions, notably in the field of reconstructive or microsurgery, to salvage tissue flaps and skin grafts whose viability is threatened by venous congestion. However, it is also important to keep it in mind as a differential diagnosis in some circumstances. This review pretends to give an actualize view of a subject that is a part of medical history.

[Jellyfish sting. An update].

Jellyfish are aquatic organisms, whose number increases under certain conditions of water temperature. They can sting humans, which can be fatal. The liberation of structures known as nematocysts induces the extrusion of the poison, to attack their victims. The poison produces characteristic local and systemic reactions. Since an increased number of these organisms has been detected in our coastline, we review the epidemiology, symptoms and diagnosis of the syndrome produced by the bite, to improve its management.
