Absence of thick, nodular melanomas during long-term surveillance with total body photography and digital dermatoscopy.

J Eur Acad Dermatol Venereol 2019 Apr 16. Epub 2019 Apr 16.

Department of Statistics and Data Science, Faculty of Statistical Studies, Universidad Complutense, Madrid, Spain.

We have read with great interest the article by Gassenmaier et al. stating that regular total body skin examination in patients with a first primary melanoma was associated with a reduction in thickness in subsequent melanomas. From a theoretical point of view, de novo fast-growing melanomas with rapid vertical growth from the outset, leading to thick nodular melanomas, would be difficult to avoid despite regular follow-up.

Usefulness of the "two-step method" of digital follow-up in early stage melanoma detection in at high risk French patients - A retrospective 4-year study.

Br J Dermatol 2019 Apr 12. Epub 2019 Apr 12.

APHP Service de Dermatologie, Hôpital Saint-Louis, Paris.

Dermoscopy was proven more accurate than naked-eye examination and sequential digital dermoscopy imaging (SDDI) superior to dermoscopy alone for melanoma detection . SDDI combined with total-body photography (TBP) namely the "two-step method" of digital follow-up (DFU), seems at present the best surveillance strategy for high risk patients. With the aim to endorse its usefulness, we retrospectively studied 148 at high risk patients included in DFU at the Dermato-oncology Unit of Hôpital Saint-Louis between 2014 and 2018. Read More

Spectrochim Acta A Mol Biomol Spectrosc 2019 Mar 19;217:294-309. Epub 2019 Mar 19.

Laboratorio Nacional de Ciencias para la Investigación y Conservación del Patrimonio Cultural, Instituto de Física, Universidad Nacional Autónoma de México, Circuito de la Investigación Científica S/N, Ciudad Universitaria, Coyoacán, C.P. 04510 Ciudad de México, Mexico. Electronic address:

The present paper proposes a methodology that complies with the requirements of identifying and characterizing jadeite (and its associated minerals) for archaeological studies, avoiding the acquisition of samples and ensuring the integrity of the object. The methodology exploits a carefully selected array of techniques (optical microscopy, UV fluorescence photography, X-Ray digital radiography, infrared and Raman spectroscopies, X-Ray fluorescence and particle induced X-ray emission spectroscopies) that, despite not definitively replacing laboratory procedures, provides a first mineral and elemental evaluation of jadeite archaeological objects. The proposed methodology was applied in the characterization of twelve different jade tones, allowing the identification of major - jadeite, albite and omphacite - and minor - pumpellyite, actinolite, analcime, rutile, grossular and titanite - mineral phases.

Jaundice Eye Color Index (JECI): quantifying the yellowness of the sclera in jaundiced neonates with digital photography.

Biomed Opt Express 2019 Mar 14;10(3):1250-1256. Epub 2019 Feb 14.

The Neonatal Care Unit, Elizabeth Garrett Anderson Wing, University College London Hospitals Trust, UK.

The sclera is arguably a better site than the skin to measure jaundice-especially in dark-skinned patients-since it is free of skin pigment (melanin), a major confounding factor. This work aims to show how the yellowness of the sclera can be quantified by digital photography in color spaces including the native RGB and CIE XYZ. We also introduce a new color metric we call "Jaundice Eye Color Index" (JECI) which allows the yellowness of jaundiced sclerae to be predicted for a specific total serum bilirubin level in the neonatal population.

Using TLA-based digital photography to monitor urine cultures, we sought to improve culture result turn-around-time (TAT) by changing the time at which a culture is first photographed and thus available for analysis/work-up (Pre1) from 18 h (16,391 cultures) to 16 h (53,113 cultures) (with a total of 24-h culture incubation in both time periods); in both time periods, cultures were set up 24/7, and culture work-up occurred during the day shift only. With this change, we observed a significant decrease in time-to-final-result TAT for positive cultures (18 h-Pre1 median: 71. Read More

High-Resolution Brain 18F-FDG Images Provided by Fully Digital PET.

Clin Nucl Med 2019 04;44(4):301-302

Université de Lorraine, INSERM, IADI, Nancy

Normal brain F-FDG PET images, consecutively recorded on analog and fully digital PET cameras in an 85-year-old woman, are depicted herein with the reconstruction methods recommended for a 2-mm voxel size on each camera and with a high-resolution reconstruction additionally developed for digital PET with a 1-mm voxel size. An enhanced gray-to-white matter contrast was consistently documented for digital PET when compared with analog PET, and was associated with a further enhancement in spatial resolution at 1-mm voxel size, as evidenced by a much clearer delineation of cortical gyri. These high-resolution images could favor the identification of brain abnormalities. Read More

Documenting archaeological thin sections in high-resolution: A comparison of methods and discussion of applications.

Geoarchaeology 2019 Jan-Feb;34(1):100-114. Epub 2018 Nov 13.

ULS Digitisation and Document Delivery, KU Leuven Leuven Belgium.

Optical thin section observations represent the core empirical basis for most micromorphological interpretations at archaeological sites. These observations, which often vary in size and shape, are usually documented through digital graphic representations such as photomicrographs, scans, or figures. Due to variability in documentation practices, however, visual thin section data can be captured with a range of methods and in many different formats and resolutions. Read More

Cone beam versus conventional computed tomography angiography volume measurement in partial splenic embolization.

Medicine (Baltimore) 2019 Feb;98(5):e14312

When performing partial splenic arterial embolization (PSE), it can be difficult to determine the embolization ratio based on 2-dimensional digital subtraction angiography (DSA) image diagnosis alone. Therefore, at our department, we conduct computed tomography (CT) imaging intraoperatively and postoperatively to determine whether the planned embolization has been achieved. In recent years, developments in interventional radiology devices have enabled diagnostic imaging using cone beam CT. Read More
