BACKGROUND There is a need for better standardization of the dermoscopic terminology in assessing pigmented skin lesions. OBJECTIVE The virtual Consensus Net Meeting on Dermoscopy was organized to investigate reproducibility and validity of the various features and diagnostic algorithms. METHODS Dermoscopic images of 108 lesions were evaluated via the(More)
Rare mutations in the gene encoding for tau (MAPT, microtubule-associated protein tau) cause frontotemporal dementia-spectrum (FTD-s) disorders, including FTD, progressive supranuclear palsy (PSP) and corticobasal syndrome, and a common extended haplotype spanning across the MAPT locus is associated with increased risk of PSP and Parkinson's disease. We(More)
BACKGROUND AND DESIGN Epiluminescence microscopy (ELM) is a clinical technique that permits in vivo visual inspection of pigmented anatomic structures of the epidermis, dermoepidermal junction, and papillary dermis. A protocol is proposed for systematic visual inspection of pigmented lesions. Seventy pigmented lesions were imaged with a digital ELM camera(More)
Recently, Coppola and colleagues demonstrated that a rare microtubule-associated protein tau (MAPT) sequence variant, c.454G>A (p.A152T) significantly increases the risk of frontotemporal dementia (FTD) spectrum disorders and Alzheimer disease (AD) in a screen of 15,369 subjects. We describe clinical features of 9 patients with neurodegenerative disease (4(More)
We performed a multicentre study to evaluate the agreement between the direct clinical diagnosis and the telediagnosis of 43 cutaneous pigmented lesions. Digital clinical and dermoscopic images of the 43 pigmented skin lesions (11 melanomas, 23 melanocytic naevi, three basal cell carcinomas, three lentigines, two seborrhoeic keratoses and one angiokeratoma)(More)
Dermoscopy (dermatoscopy, epiluminescence microscopy) is an additional measure for making the diagnosis of pigmented skin lesions more accurate. It enables the clinician to visualize features not discernible by the naked eye. By applying enhanced digital dermoscopy and a standardized gross pathology protocol to pigmented skin lesions, a precise(More)
.The principal statistical properties of the RR interval sequence during atrial fibrillation are reviewed. A simple quantitative electrophysiologic mode! is presented which successfully accounts for these statistical features. In this model the atrioventricular junction (AVJ) is treated as a single cell equivalent characterizd by a refractory period and(More)
