Early Lung Ultrasound Findings in Patients With COVID-19 Pneumonia: A Retrospective Multicenter Study of 479 Patients.

Objectives: Lung ultrasound (LUS) holds the promise of an accurate, radiation-free, and affordable diagnostic and monitoring tool in coronavirus disease 2019 (COVID-19) pneumonia. We sought to evaluate the usefulness of LUS in the diagnosis of patients with respiratory distress and suspicion of interstitial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia, in comparison to other imaging modalities.

Methods: This was a multicenter, retrospective study.

Extended Lymphadenectomy in Locally Advanced Rectal Cancers: A Systematic Review.

Purpose: The surgical treatment of advanced low rectal cancer remains controversial. Extended lymphadenectomy (EL) is the preferred option in the East, especially in Japan, while neoadjuvant radiotherapy is the treatment of choice in the West. This review was undertaken to review available evidence supporting each of the therapies.

Right Colectomy for Cancer: A Matched Comparison of Three Different Surgical Approaches.

Purpose: The standard approach to right colon cancer resection is still a matter of debate and includes laparoscopy, open midline incision, or open transverse incision. We aimed this study to compare the short- and long-term results of laparoscopic right-colectomy with those provided by the open approaches.

Methods: Of the 176 patients who underwent right-colectomy at our Department for nonmetastatic colon cancer, 40 patients treated by laparoscopy, 40 treated by transverse incisions, and 40 treated by midline incisions were selected and matched using the propensity score method.

Synchronous gastric adenocarcinoma and pancreatic ductal adenocarcinoma.

Background: The association between gastric and pancreatic carcinoma is a relatively rare condition. In gastric carcinoma patients, the prevalence of second tumors varies 2.8% to 6.

Triple synchronous tumours of the urinary system with different histologies: a case report.

We present the case report of a male patient with a diagnosis of synchronous kidney, bladder and prostate tumours with different histologies: renal oncocytoma, urothelial carcinoma of the bladder, and adenocarcinoma of the prostate. This is the first case report described in the literature in which a complete surgical resection of triple tumours has been performed with surgery in a single session. Recent advances in the field of genetics enable the surgeon to hypothesise new strategies in the early treatment of synchronous tumours, particularly when a number of common tumour markers are positive.

A rare case of aggressive squamous-cell carcinoma of the breast skin: Marjolin's ulcer. A case report.

Marjolin's ulcer is an epidermoid carcinoma arising in a scar or chronic wound and is characterised by an aggressive course. We present a clinical case of ulcerated skin carcinoma of the breast arising in an 80-year-old woman, who at history taking reported a burn occurring 30 years earlier on the breast skin, with subsequent chronic ulcerative scar formation. The definitive histological examination identified a "squamous-cell carcinoma of the breast skin".
