AI-driven big web redesign: two case studies in Italian universities

This paper explores the challenges of web redesign in Public Administration (PA), particularly within universities. Universities often struggle with fragmented online presences due to distributed editorial models and diverse communication needs across research, education, and dissemination activities. Limited resources further restrict investment in upskilling staff and adopting modern technologies. Open source solutions, though cost-effective, are often chosen without considering user experience. We present a methodology that combines user-centered design, Artificial Intelligence (AI), and ”radical collaboration” to achieve a future-proof and scalable redesign. Starting from a case study of a major web redesign project at an Italian university (2014-2020) involving hundreds of websites and over 200 content editors, the paper details the process, including a large-scale content audit using AI, single sourcing with AI-powered content transformation, and user experience (UX) testing with data visualization. This approach resulted in a unified, user-centric online presence and garnered recognition, including the ForumPA award for best innovator. The paper concludes by discussing the applicability of this methodology to other PA institutions facing similar challenge

Benign lymphoepithelial parotid lesions in HIV-positive patients: spectrum of findings at gray-scale and Doppler sonography.

Benign lymphoepithelial lesions are intraparotid nodules that develop as an early manifestation of HIV infection. The purpose of this study was to describe the spectrum of sonographic and Doppler findings of benign lymphoepithelial lesions in HIV-positive patients and to assess whether these findings are specific for the diagnosis of such lesions.Nine HIV-positive patients with swelling of the parotid gland caused by single or multiple parotid nodules were evaluated. Fourteen nodules were identified sonographically and proved to be benign lymphoepithelial lesions at cytologic examination. They were assessed with gray-scale, duplex, color Doppler, and power Doppler sonography. For each nodule, the echogenicity, grade and pattern of vascularity, and spectral tracings were evaluated.Benign lymphoepithelial lesions manifested as parotid nodules with a wide spectrum of sonographic appearances, ranging from simple cysts to mixed masses with predominantly solid components. Cystic lesions (10/14) were not purely anechoic; they had an internal network of thin septa supplied by vessel pedicles and, in four of 10 cases, a solid mural nodule. On the other hand, mixed nodules (4/14) had a higher conspicuity of solid tissue and thicker stromal septa, thus resembling a parotid neoplasm more than a cyst. The overall grade of vascularity of benign lymphoepithelial lesions varied from avascular to intensely hypervascular. Generally, mixed nodules were more hypervascular than were the cystlike ones. Spectral analysis showed slow velocity (peak systolic velocity range, 8-28 cm/sec; mean, 20 20 cm/sec) and low impedance (resistive index range, 0.36-0.70; mean, 0.57) arterial flows.The spectrum of sonographic and Doppler features of benign lymphoepithelial lesions in HIV-positive patients is broad. Sonographic findings are non-specific for the diagnosis of such lesions, especially in cases of mixed solid-cystic isolated nodules

US imaging and color Doppler in patients undergoing inhibitory therapy with calcitriol for secondary hyperparathyroidism.

The aim of this study was to evaluate the changes in volume, structure, and flow pattern of parathyroid glands in uremic patients with secondary hyperparathyroidism treated with long-term intravenous calcitriol (CTL) therapy. Ultrasonography was used to follow-up volume changes occurring in 18 enlarged glands in 11 patients during an 18-month period; in 6 of these cases, 11 glands were followed-up also with color-Doppler to monitor variations in flow pattern. Vascularization was classified using three grades: grade 0 = no color signal; grade I = vessels covering less than 50 \% of glandular cross-sectional area; grade II = vascular signals covering more than 50 \% of glandular cross-sectional area. No significant changes in volume were demonstrated during the 18 months of follow-up. On the contrary, significant decrease in flow was observed with almost complete disappearance of color-Doppler signals. This finding related well with the observed decrease in parathormone blood levels. Lack of volume changes during medical therapy demonstrates the inability of US alone to monitor the effect of this treatment on the parathyroid glands. Conversely, the observed intraglandular flow reduction indicates the possibility to use color Doppler to monitor the effects of CLT in uremic hemodialyzed patients with secondary hyperparathyroidism. This imaging procedure can be proposed for follow-up of the response of the parathyroid glands to therapy

[Computerized tomography-guided neurolytic block of the splanchnic nerve].

CT-guided neurolytic splanchnic nerve block is a technique for relieving abdominal cancer pain; the goal is the alcoholic neurolytic interruption of the sensitive structures in retroperitoneal space. CT yields accurate anatomical detailing and the course for needle placement and alcohol spread. January, 1993, to July, 1996, twenty-one bilateral splanchnic nerve blocks were performed through the posterior access. Forty-eight hours after alcoholization, 14 patients (66\%) had complete pain regression; 52\% of the patients needed no analgesics for 6 to 54 days and only 9 patients (42\%) needed another low opioid therapy. Complications included hypotension and diarrhea in all cases. One had a cardiac arrest and died 8 days after the procedure. There were no other complications. The whole procedure usually lasted 60 min (range: 45 to 90 min). Splanchnic nerve neurolysis is a useful treatment in the patients with severe chronic abdominal pain. It is used as a second line treatment when large lesions change celiac anatomy and complicate the percutaneous block of the celiac plexus

Possible malignant transformation of benign lymphoepithelial parotid lesions in human immunodeficiency virus-infected patients: report of three cases.

Benign lymphoepithelial parotid lesions (BLL) are intraparotid pathological changes that are commonly thought to be an early manifestation of human immunodeficiency virus (HIV) infection. It is not well known whether BLL may undergo malignant transformation into B cell lymphoma and may therefore be a sort of precancerous lesion. We report 3 cases of possible malignant transformation of BLL in HIV-infected patients
