Extensive intracranial involvement with multiple dissections in a case of giant...

A 56-year-old man presented with weight loss, articular pain and minor neurological symptoms progressing over 1 month. Neurosonological evaluation suggested occlusion in intracranial segments of the left vertebral artery (VA) and of both internal carotid arteries (ICA) and hypoechoic halo sign in both superficial temporal arteries. The diagnosis of giant cell arteritis was supported by inflammatory markers and ...

Using a cohesive damage model to predict the tensile behaviour of CFRP single-s...

This work addresses both experimental and numerical analyses regarding the tensile behaviour of CFRP single-strap repairs. Two fundamental geometrical parameters were studied: overlap length and patch thickness. The numerical model used ABAQUS® software and a developed cohesive mixed-mode damage model adequate for ductile adhesives, and implemented within interface finite elements. Stress analyses and strength ...

Leukocytoclastic vasculitis. Review of 51 cases.

Leukocytoclastic vasculitis (L.V.) is a polymorphous inflammatory dermatosis, characterized clinically by palpable purpura of the lower legs and, histologically by fibrinoid change in the small dermal vessels as well a polymorphonuclear infiltrate and nuclear dust. Fifty one cases (33 females and 18 males) of histologically confirmed L.V., seen at the Dermatologic Clinic, University Hospital of Coimbra, are rev...

Skin pathology in kidney transplant recipients.

Since 1990, 82 unselected renal allograft recipients were evaluated in order to establish the incidence of cutaneous disorders. This pathology was related to the period of immunosuppression according to time of transplantation: 0-3 months; 3-12 months; 12-36 months and beyond 36 months. Most of them were on triple immunosuppression (cyclosporine A, azathioprine and prednisone)--(51); Twenty-two also associated ...
