Between October 19-22, 2021, in very special conditions (Coronavirus 19 pandemic), the XIIIth SOROT Congress took place online, with a full success and unanimous appreciation.

Sarcoidosis is a multisystem inflammatory disease of incompletely elucidated etiology. It is characterized by the formation of non-caseating granulomas which can be found in any organ or tissue. The most commonly affected organ is the lung and the typical presentation is with bilateral hilar lymphadenopathy, pulmonary infiltrates, and cutaneous and ocular symptoms. However, as the granulomatous reaction can take place in any organ and tissue, sarcoidosis can have variable clinical presentations. It is well documented that sarcoidosis may mimic a great array of autoimmune and non-autoimmune diseases. Moreover, it can also coexist with these disorders, which makes the diagnostic pathway all the more challenging.

Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are precancerous lesions. Anatomically, IPMNs are classified as main duct-type and branch duct-type. Histologically, these neoplasms are grouped into 4 categories: intestinal, pancreatobiliary, oncocytic, and gastric. Patients diagnosed with IPMN have been shown to have an increased risk of malignancy of the pancreatic tumor, but also an increased risk of associating cancers with extrapancreatic localization. Among the factors associated with the risk of malignancy of IPMNs are the involvement of the main pancreatic duct or branch duct, tumor size, diameter of the main pancreatic duct, and histological type. Regarding IPMN-associated extrapancreatic cancers, gastric adenocarcinoma and colorectal adenocarcinoma were the most reported.

Background: With the recent increase in the number of patients admitted to Intensive Care Units with respiratory failure and the need for fast, reliable, repeatable, non-invasive, little or no radiation examinations, lung ultrasound has emerged as an attractive alternative to chest radiography. Summary: Despite the relatively short learning curve for the physician, the possibility of using ultrasound examination on any patient, no matter the age or medical history, there are some patient-related limitations to be considered (mechanically ventilated patients, non-compliant patients). With the progression of literature on this topic, new protocols have emerged, aiming to minimize the intra- and inter-observer variability. Bedside Lung Ultrasound in Emergency Protocol proposes a guided, step-by-step approach, helpful for diagnosing or ruling out life-threatening lung pathologies.

Rheumatoid arthritis (RA) is the most encountered chronic inflammatory rheumatic condition with a predominance in middle-aged women. If inadequately controlled and in the presence of risk factors, RA can lead to complications such as septic arthritis. The case presentation displays a 55-year-old female patient with a long history of RA that developed infection of the knee after repeated arthrocentesis for persistent arthritis. Empirical double parenteral antibiotherapy and methylprednisolone were initiated leading to favorable patient outcome before irreversible damage occurred. Septic arthritis should be considered in patients having chronic inflammatory diseases, especially if under immunosuppressive drugs and corticosteroids. Prompt intervention can decrease morbidity in RA patients.
