BACKGROUND Reactive perforating collagenosis (RPC) is a rare form of transepithelial elimination, in which altered collagen is extruded through the epidermis. There are 2 types of RPC, acquired RPC (ARPC) and inherited RPC, while the latter is extremely rare. Here we report on 1 case of ARPC. METHODS A 73-year-old female was presented with strongly itchy papules over her back and lower limbs ...

BACKGROUND AND PURPOSE Different studies already demonstrated the benefits of 7T for precontrast TOF-MRA in the visualization of intracranial small vessels. The aim of this study was to assess the performance of high-resolution 7T TOF-MRA after the administration of a gadolinium-based contrast agent in visualizing intracranial perforating arteries. MATERIALS AND METHODS Ten consecutive patien...

Sweet's syndrome, or acute febrile neutrophilic dermatosis, is a condition characterized by the sudden onset of fever, leukocytosis, and tender,erythematous, well-demarcated papules and plaques which show dense neutrophilic infiltrates on histologic examination. Although it ma occur in the absence of other known disease, Sweet's syndrome is often associated with hematologic disease (including l...

AIMS To assess the aetiological factors associated with the occurrence of perforating ocular injuries in children in an urban setting and to assess the visual outcomes of such injuries. METHODS All cases of perforating ocular injury presenting to a single paediatric hospital (age less than 16 years) over a 17 year period were identified by a medical record search. All new cases of perforating...

The effects of noradrenaline (Nor) and phenylephrine (Phe) on the isolated, non-precontracted perforating branch of the human internal mammary artery (HIMA) were investigated. Nor and Phe induced concentration-dependent contractions of intact and endothelium-denuded arterial rings with no statistically significant differences between the pEC(30) and maximal response values. The pretreatment of ...

Transepidermal elimination (TE) is a mechanism whereby foreign or altered constituents can be removed from the dermis. This process involves unique morphologic alterations of the epidermis, which forms a channel and thereby facilitates extrusion of the desired dermal components. The phenomenon of TE may occur as a primary process characterizing disorders, such as elastosis perforans serpiginosa...

We report a novel technique that fuses 3D digital subtraction angiograms and MR images. Image fusion was successfully performed within 20 minutes each in 11 consecutive cases. Our initial experience showed that this image fusion enabled clear and simultaneous visualization of perforating arteries and surrounding tissues. The relation between perforating arteries and normal brain or lesions was ...

The results of the examination and surgical treatment of 132 patients with CEAP class C2-C6 varicose disease of the lower extremities have been analyzed. A combined diagnostic method that allows detecting the peculiarities of the functioning of the perforating vein venous system of the shin, namely, allows establishing the uncompetency of the perforating veins of the shin objectively, has been ...

The objective of this study was to introduce a method for repairing large soft-tissue defects on the foot. Distally based neuro-fasciocutaneous flaps with perforating vessels were designed along the saphenous and sural neurovascular axes. The cutaneous perforating branches of the major arteries of the lower extremities were used as pedicles, which provided a rotation arc for the cross-leg flap ...
