A field study of lead phytoextraction by various scented Pelargonium cultivars.

Phytoremediation appears to be a promising technique for metal soil clean up, although its successful application on a large scale still remains a challenge. Field experiments for six scented Pelargonium cultivars, conducted on two Pb-contaminated calcareous and acidic soils, revealed vigorous plant growth, with no symptoms of morpho-phytotoxicity in spite of high Pb accumulation levels. Lead contents in the harvestable parts of all plants grown on the acidic and more contaminated soil were significantly higher than those grown on the calcareous soil.

[Cranial wounds of the skull caused by a fencing-foil].

Unlabelled: Penetrating stab cranial wounds of the skull by fencing-foil are rare in western countries.

Case Report: This 46-year-old man suffered a penetrating stab wound of the skull through the right orbital region. As a consequence he developed an intracranial hematoma requiring surgical evacuation.

[Descompresive craniectomy in head injury. Intractable I.C.P. ].

Decompressive craniotomy is a neurosurical technique known since the origin of neurosurgery, but its use as a routine started at the end of the 19th century. In last decades, the use of decompressive craniotomy decreased, mainly because of poor results obtained and the advances in medical treatment of refractory intracranial hypertension in the Intensive Care Units. Nevertheless, in recent years there has been a renewed interest with the use of this surgical techique in young patients with head injuries and severe intracranial hypertensio'n, but no surgical mass lesion, as well as in patients with ischemic stroke causing life threatening mass effect.

[Recurrent meningiomas with progressive aggressiveness and posterior extracranial extension].

Meningiomas are in most cases benign tumors. They represent about 15% of primitive intracranial tumors. Complete surgical resection achieves healing in the majority of patients.
