Quantitative ultrasound (US) elastography (Q-USE), able to evaluate tissue stiffness has been indicated as a new diagnostic tool to differentiate benign from malignant thyroid lesions. Aim of this prospective study, conducted at the Department of Surgical Sciences, of the “Sapienza” University of Rome, was to evaluate the diagnostic accuracy of Q-USE, compared with US parameters, in thyroid nodules with indeterminate cytology (Thy3).The case study included 140 nodules from 140 consecutive patients. Patient’s thyroid nodules were evaluated by Q-USE, measuring the strain ratio (SR) of stiffness between nodular and surrounding normal thyroid tissue, and conventional US parameters prior fine-needle aspiration cytology. Those with Thy3 diagnosis were included in the study. Forty of the nodules analyzed harbored a malignant lesion. Q-USE demonstrated that malignant nodules have a significant higher stiffness with respect to benign one and an optimun SR cut-off value of 2.05 was individuated following ROC analysis. Univariate analysis showed that hypoechogenicity, irregular margins and SR >2.05 associated with malignancy, with an accuracy of 67.2%, 81,0% and 89.8%, respectively. Data were unaffected by nodule size or thyroiditis. These findings were confirmed in multivariate analysis demonstrating a significant association of the SR and the irregular margins with thyroid nodule’s malignancy. In conclusion, we demonstrated the diagnostic utility of Q-USE in the differential diagnosis of thyroid nodules with indeterminate cytology that, if confirmed, could be of major clinical utility in patients’ presurgical selection.

Introduction Recently, Italy has been heavily hit by COVID-19 pandemic and today it is still one of the most affected countries in the world. The subsequent necessary lockdown decreed by the Italian Government had an outstanding impact on the daily life of the entire population, including that of Italian surgical residents' activity. Our survey aims to evaluate the impact of COVID-19 on the training programme of Italian surgical residents. Materials and methods We designed a 12-item-electronic anonymous questionnaire on SurveyMonkey© web application. The survey was composed of different sections concerning demographic characteristics and impacts of COVID-19 on the concrete participation in clinical, surgical and research activities. Future perspectives of responders after the pandemic were also investigated. Results Eighty hundred responses were collected, and 756 questionnaires were considered eligible to be included in the study analysis. Almost 35 and 27% of respondents experienced, respectively, complete interruption of surgical and clinical activities. A subgroup analysis, comparing the COVID-19 impact on clinical activities with demographics data, showed a statistically significant difference related to specialties (p = 0.0062) and Italian regions (p < 0.0001). Moreover, 112 residents have been moved to non-surgical units dealing with COVID-19 or, in some case, they voluntarily decided to interrupt their residency programme to support the ongoing emergency. Conclusion Our survey demonstrated that COVID-19 pandemic has severely impacted the educational programme of Italian surgical residents. Despite many regional differences, this survey highlighted the overall shortage of planning in the reallocation of resources facing this unexpected health emergency.

Aim Social media are used daily by both healthcare workers and patients. Online platforms have the potential to provide patients with useful information, increase their engagement and potentially revolutionize the patient-physician relationship. This survey aimed to evaluate the impact of the Internet and social media (I&SM) on patients affected by colorectal and proctological diseases to define a pathway to develop an evidence-based communications strategy. Method A 31-item anonymous electronic questionnaire was designed. It consisted of different sections concerning demographics and education, reason for the visit, knowledge of the diseases, frequency of I&SM use and patients' opinions about physicians' websites. Results Over a 5-month period, 37 centres and 105 surgeons took part in the survey, and a total of 5800 patients enrolled. Approximately half of them reported using the Internet daily, and 74.6% of the study population used it at least once per week. There was a correlation (P < 0.001) between those who used the Internet for work and those who had knowledge of both symptoms and the likely diagnosis before consultation. Patients who used the Internet daily were more likely to request a consultation within 6 months of symptom onset (P < 0.0001). Patients with anorectal diseases were more likely to know about their disease and symptoms before the visit (P < 0.001). Conclusion Colorectal patients use I&SM to look for health-related information mainly after their medical visit. Surgeons and hospital networks should plan a tailored strategy to increase patient engagement, delivering appropriate information on social media.

Gastrointestinal anisakiasis is a parasitic infection occurring in people that consume raw or inadequately cooked fish or squid. It is frequently characterized by severe epigastric pain, nausea and vomiting caused by the penetration of the larvae into the gastric wall. Acute gastric anisakiasis with severe chest discomfort is rarely reported in Italy. On the other hand, gastro-allergic anisakiasis with rash, urticaria and isolated angioedema or anaphylaxis is a clinical entity that has been described only recently. Also, if patients usually develop symptoms within 12 hours after raw seafood ingestion, not always endoscopic exploration can promptly identify the Anisakis larvae. Moreover, some authors consider the prevailing allergic reaction as a natural and effective defense against the parasitic attack. We report two cases of peculiar manifestations of anisakiasis in both acute and chronic forms (severe chest discomfort and anaphylactoid reaction).
