Reactive Perforating Collagenosis

Abstract Background Acquired reactive perforating collagenosis (ARPC) is a rare form of transepithelial elimination in which altered collagen is extruded through the epidermis. Case presentation A 23-year-old male presented with cup-like ulcerated lesions on his limbs since 3 months. A series of serological and immunological tests showed no abnormalities. A diagnosis of ARPC was based on skin biopsy findings. The patient was cured using treatment with itraconazole for 8 weeks, in the absence of a fungal infection. Conclusions The anti-inflammatory and anti-angiogenic effects of itraconazole can have good therapeutic benefits for ARPC.

Progressive Macular Hypomelanosis (PMH) is a common but often misdiagnosed disorder of acquired hypopigmentation. An adolescent female presented with irregular, hypopigmented patches ultimately diagnosed as PMH. Complete repigmentation was achieved with narrowband UVB phototherapy, benzoyl peroxide wash, and clindamycin lotion.

Hardened Cement Paste

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.
