BACKGROUND Microdermabrasion has become a popular method of skin rejuvenation for treating dyschromia, fine wrinkles, and mild scarring. OBJECTIVE To analyze the onset and extent of the dermatologic changes associated with microdermabrasion. METHODS Ten volunteers, ages 31-62 years, underwent a series of six aluminum oxide microdermabrasion facial treatments 7-10 days apart. Skin biopsy spe...
BACKGROUND Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition that commonly affects the clavicle and pelvis. CASE PRESENTATION We report here a case a 12 years old girl with CRMO arising with recurrent episodes of left supraorbital headache, followed by the appearance of a periorbital dyschromia. Magnetic resonance imaging (MRI) of the skull and orbits revealed an important...
The nail, a fast-growing organ, is sensitive to changes in the germinal matrix, and, as would be expected, a severe systemic illness can affect the growth rate of the ungual matrix, which occasionally results in temporary growth arrest (Beau’s line). Thus, recovery from growth arrest can be associated with onychomadesis, also called nail shedding, a condition that indicates the separation of th...
A new skeleton of the exceedingly rare, late Carboniferous eureptile Anthracodromeus longipes ( Carroll and Baird, 1972 ), reveals presence a reduced phalangeal count in manus pedes uniquely recurved unguals. With these data, we quantitatively evaluate locomotor ecology using morphometric analyses proportions, ungual curvature, shape. Our findings indicate that anatomy likely facilitated scanso...
An extremely well-preserved dinosaur (Cf. Edmontosaurus sp.) found in the Hell Creek Formation (Upper Cretaceous, North Dakota) retains soft-tissue replacement structures and associated organic compounds. Mineral cements precipitated in the skin apparently follow original cell boundaries, partially preserving epidermis microstructure. Infrared and electron microprobe images of ossified tendon c...
The presence of granulomas in the skin of T-cell lymphoma patients is a rare but well-known phenomenon. The authors present the case of a 44-year-old Caucasian male, with a previously treated peripheral T-cell lymphoma, with cutaneous infiltration and extensive dyschromia on his lower limbs. Skin biopsies revealed the presence of sarcoid granulomas associated with the recurrence of the lymphoma...
This paper reports the clinical experience of a multi-center, multiple physician trial with a novel fractional radiofrequency ablative skin resurfacing and rejuvenation device (Fractora, Invasix, Israel) deployed on both Caucasian skin types I III and Asian skin type IV. Histological study demonstrated deep ablation and collagen restructuring in the papillary and reticular dermis. The Fractora ...
