Abstract

The Meixoeiro Hospital Brain Bank (BB) was established at the end of 2002. A BB is a tissue collection and storage system, established under the best conditions to carry out prospective morphological, biochemical or molecular studies. The BB should ideally be supported by a donor program, although samples may also be obtained from autopsy material from patients with neurodegenerative diseases. Recruitment of control cases from brains without neurological diseases is basic. The main goal of a BB is to provide brain tissue for research. Each case requires accurate clinical data, a definite diagnosis and optimal conditions of tissue preservation. The use of protocols to standardize the handling and processing of tissues, data recruitment and neuropathological diagnosis is fundamental to assure the quality and homogeneity of samples. Close collaboration between neuropathologists, neurologists and other specialists is essential in all the process. Although important advances in the tissue banking field have been achieved, the number of donors in Spain still remains low. Stronger institutional support as well as public awareness through better diffusion of the information is necessary to increase the number of donors and improve BB development.

13. Clinical and Pathological Features of Persistent Decorative Tattoo Reactions.

Author

Suárez-Peñaranda JM, Fachal C, Blanco-Bellas M, Ginarte M, Monteagudo B, León A, and González-Carril F

Abstract

Persistent, non-infectious medical complications arising from decorative tattoos have increased considerably. They are difficult to characterize clinically, and histopathology shows a wide variety of overlapping patterns, with lichenoid and granulomatous dermatitis being the most common findings. Both clinical and pathological findings are difficult to ascribe to particular ink colour. The findings in 30 biopsies from 28 patients with persistent reactions in decorative tattoos are reported, including immunohistochemical findings., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Journal of Dermatology.)

Abstract

Skin tags are common benign neoplasm located predominantly in intertriginous skin. Generally of cosmetic concern, they can be easily treated with cryotherapy, electrodessication or snip-excision. Despite their high incidence data about their etiopathogenesis are scarce in the medical literature. We describe a patient who developed multiple skin tags arranged in a linear fashion suggesting an etiopathogenic role for friction.
