Balanitis xerotica obliterans: An observational, descriptive and retrospective clinical study.

Lichen sclerosus is a chronic disease of unknown etiology that can occur in the genital area of both sexes. Balanitis xerotica obliterans (BXO) occurs only in the genital area of men and typically affects the foreskin, penile glans, and/or the meatus. In the present report, an observational, descriptive, and retrospective epidemiological clinical study of available data between January 2006 and December 2020 in patients diagnosed with BXO from the casuistic of CMI DERMAMED (Târgu Mureș, Romania) was performed. During this 15-year period, 164 patients were diagnosed with BXO, of whom 70 (42.8%) were in the 51-60-year-old age group. They presented at the medical consultation at 3-9 months after onset of symptoms, where 124 (75.6%) the patients were found to be with stage III of the disease. The most important comorbidities were found to be diabetes mellitus and obsesity, who were treated with potent steroids (betamethasone and clobetasol) with favorable results, with only nine (5.48%) cases necessitating surgical treatment. In general, BXO is a rare, acquired, non-infectious and chronically inflammatory (autoimmune) skin disease that has an unknown etiology. Although the risk of developing this condition is particularly high in patients in the 40-60-year-old age group, it can occur at any age. In the present report, the majority of the patients presented after a long period of disease development, such that they were already in advanced stages of the condition with clinically subjective symptoms and severe sexual problems. This delay in diagnosis has several causes, including misdiagnosis, psychological issues, and sexual behavior. Diabetes mellitus and overweight/obesity tended to be important comorbidities of BXO since the majority of the patients were also affected by these conditions. These comorbidities can exert an important pathophysiological influence on BXO. The first-line treatment option for this condition is the local application of potent steroids, with favorable effects. Due to the risk of malignant transformation as a result of BXO, it is recommended that these patients should be followed up for a longer period.

Making data matter: Voxel printing for the digital fabrication of data across scales and domains.

We present a multimaterial voxel-printing method that enables the physical visualization of data sets commonly associated with scientific imaging. Leveraging voxel-based control of multimaterial three-dimensional (3D) printing, our method enables additive manufacturing of discontinuous data types such as point cloud data, curve and graph data, image-based data, and volumetric data. By converting data sets into dithered material deposition descriptions, through modifications to rasterization processes, we demonstrate that data sets frequently visualized on screen can be converted into physical, materially heterogeneous objects. Our approach alleviates the need to postprocess data sets to boundary representations, preventing alteration of data and loss of information in the produced physicalizations. Therefore, it bridges the gap between digital information representation and physical material composition. We evaluate the visual characteristics and features of our method, assess its relevance and applicability in the production of physical visualizations, and detail the conversion of data sets for multimaterial 3D printing. We conclude with exemplary 3D-printed data sets produced by our method pointing toward potential applications across scales, disciplines, and problem domains.
