Ectopic plantar nail: a report of two cases.
No full textAbstract
Ectopic nail is an extremely rare condition related to acquired or congenital anomalies. Almost 40 cases are reported in the literature, mostly in Japanese patients. In the majority of these patients, ectopic nails developed in the dorsal aspect of the fingers; they are associated in some cases with acquired or congenital growth anomalies or to polydactyly. Recently, we observed two male adult patients with true ectopic nails of the foot (sole and heel). Both patients were not affected by ectodermic dysplasia or foot malformations. The lesion relapsed after surgical excision in one case. Histology showed features of a well-developed and normal nail plate and matrix. A transmission electron microscope study was done in one case, showing typical aspects of onychocytes. The other nail was reproduced by a silicone replica technique and its superficial texture, shape and relationship with surrounding tissue were analysed by scanning electron microscopy

No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Microscopic and immunohistochemical analysis of the skin changes of free forearm flaps in intraoral reconstruction
No full textIn the literature, few studies based on clinical and histological
evaluation analyze skin structural changes after transplantation to
the oral cavity. Ten patients affected by squamous cell carcinoma
of the oral cavity who were reconstructed with a free forearm flap
were included in the current study to analyze skin alterations. The
authors performed a histological and ultrastructural evaluation of
skin samples from the free forearm flap before transplantation
and 18 months after intraoral reconstruction. They analyzed
cytokeratin and involucrin distribution, which represent markers
of maturation and differentiation of epithelia. The aim of this
study was to demonstrate whether skin “mucosalization” occurs.
They found that the skin undergoes some morphological changes
induced by the intraoral environment. Cytokeratin and involucrin
distribution is mostly unchanged. This aspect is in favor of skin
structure preservation. Thus, they found that “mucosalization” of
the skin is not evident after 18 months
