Pigmented villonodular synovitis of any joint in the extraarticular region is very rare. Its clinical and radiological differential diagnosis is difficult due to exhibiting findings of any soft tissue tumor. Here we report an extrarticular pigmented villonodular synovitis case of the hip of a five-year-old boy, with its radiological and histopathological aspects. The mass was completely extraar...

Behavioral measurements on the water maze show night blindness in albino mice but cortical recordings show no difference between pigmented and congenic albino mice. Consequently we have measured the absolute threshold in albino and pigmented mice using an operant method. The estimated threshold value is -5.3 log cd/m2 for albino mice and -5.5 log cd/m2 for the pigmented mice. We conclude that t...

This paper shows that adding 3D depth information to RGB colour images improves segmentation of pigmented and non-pigmented skin lesion. A region-based active contour segmentation approach using a statistical model based on the level-set framework is presented. We consider what kinds of properties (e.g., colour, depth, texture) are most discriminative. The experiments show that our proposed met...

Trichoblastoma is occasionally observed in association with a pre-existing nevus sebaceous in the Korean literature. However, there has been no report on the pigmented type. Herein, we report the first Korean case of a pigmented trichoblastoma arising from the nevus sebaceous on the forehead. A 28-year-old male presented with a dark nodular lesion within a yellowish plaque on the forehead. The ...

Abstract Lacydonia Marion & Bobretsky, 1875 is the sole genus in family Lacydoniidae Bergström, 1914. We herein describe new species of shohoensis sp. nov. from 2042-m deep bottoms at Shoho Seamount Nishi-Shichito Ridge, Northwest Pacific Ocean. It most similar to L. anapaulae Rizzo et al ., 2016 having a depression on median anterior region and lacking lateral lobes posterior margin prosto...

BACKGROUND Outcome measures for atopic dermatitis (AD) patients with pigmented skin have neither been developed nor validated. OBJECTIVE To compare the reliability and validity of four common AD outcome measures in patients with various levels of skin darkness. METHOD The inter- and intra-rater reliability and construct validity of the EASI (Eczema Area and Severity Index), objective-SCORin...

Connexin43 is a major component of the gap junctions between pigmented and non-pigmented cells of the double-layered epithelium in the ciliary body of the eye. We directly tested the hypothesis that gap junctions play a crucial role in the production of the aqueous humor by inactivating the GJA1 (connexin43) gene in the pigmented epithelium with cre-loxP technology. To accomplish this, we cross...

Four cases of villonodular synovitis were diagnosed by histopathology. All four dogs were treated medically with either carprophen or a combination of carprophen and glucosamine complex (Cosequin). In three of the dogs the condition improved significantly, and these dogs returned to normal workload.
