Complications of lymphoma in the abdomen and pelvis: clinical and imaging review.

Involvement of the abdomen and pelvis is common in lymphoma. Nodal and extranodal abdominal and pelvic lymphoma may present with various complications. Complications are most common in high-grade lymphomas, especially diffuse large B-cell lymphoma.

Critical infections in the head and neck: A pictorial review of acute presentations and complications.

Non-traumatic head and neck emergencies include several disease processes such as infectious, inflammatory, and malignant. Infections are among the most common pathological processes that affect the head and neck, and are particularly important due to their acute, severe, and potentially life-threatening nature. Radiologists need to be well acquainted with these entities because any delay or misdiagnosis can lead to significant morbidity and mortality.

Neoadjuvant cemiplimab for resectable hepatocellular carcinoma: a single-arm, open-label, phase 2 trial.

Background: Surgical resection of early stage hepatocellular carcinoma is standard clinical practice; however, most tumours recur despite surgery, and no perioperative intervention has shown a survival benefit. Neoadjuvant immunotherapy has induced pathological responses in multiple tumour types and might decrease the risk of postoperative recurrence in hepatocellular carcinoma. We aimed to evaluate the clinical activity of neoadjuvant cemiplimab (an anti-PD-1) in patients with resectable hepatocellular carcinoma.

Pituitary incidentalomas in paediatric population: Incidence and characteristics.

Objective: To determine the incidence of pituitary incidentalomas in the paediatric population and among its different age subgroups as well as to identify the characteristics of these lesions. Additionally, we aim to give a perspective on the management and follow-up of these patients.

Design And Patients: We retrospectively studied MRI of children aged 18 years or below who underwent MRI with sellar region within their field of view between January 2010 and December 2018.

Copper-Catalyzed 8-Aminoquinoline Assisted Aryl Chalcogenation of Ferroceneamide with Aryl Disulfides, Diselenides, and Ditellurides.

A synthetic method has been developed for the synthesis of unsymmetrical ferrocene aryl chalcogenides by C-H activation of ferroceneamide using 8-aminoquinoline as a directing group, aryl dichalcogenides, and copper(II) catalyst in the presence of silver acetate oxidant at 80 °C in DMSO. The developed methodology is quite general and mild to access three unsymmetrical diaryl chalcogenides (sulfide, selenide, and telluride) and also amenable to aryl dichalcogenides with sensitive bromo, chloro, and nitro functionalities. Further, ferrocene aryl tellurides have been obtained in moderate yields for the first time by the developed C-H activation approach.
