Risk factors for subdural bleeding in elderly population.

In the elderly, a larger proportion of the intracranial bleeds is related to non-traumatic causes or is caused by slight trauma--such that in a younger patient would not be expected to cause a bleed. In clinical practice, there is a prevailing impression that these bleeds, especially subdural hematomas of chronic and sub-chronic duration with or without acutization (evidence of "fresh" bleeding) are in many cases related directly to the use of anticoagulant therapy. A retrospective survey of medical documentation was performed for patients treated at the Neurosurgery Clinic of KBC Rijeka during the period of 2011 and 2012.

Melanoma sentinel lymph node biopsy: analysis of cases operated on from 1999 to 2008 in The University Hospital Dubrava, Zagreb, Croatia.

Title: Melanoma Sentinel Lymph Node Biopsy: analysis of cases operated on from 1999-2008 in the University Hospital Dubrava, Zagreb, Croatia.

Aim: To determine how well tumor thickness, ulceration, location and patient age and sex predict a positive sentinel lymph node in the analyzed population.

Patients And Methods: 321 patients were included in the study.
