Pneumatosis intestinalis (PI) is an uncommon medical condition in which gas pockets form in the walls of the gastrointestinal tract. The mechanism by which this occurs is poorly understood; however, it is often seen as a sign of serious bowel ischemia, which is a surgical emergency. Since the early days of solid organ transplantation, PI has been described in recipients of kidney, liver, heart, and lung transplant. Despite the dangerous connotations often associated with PI, case reports dating as far back as the 1970s show that PI can be benign in solid organ transplant recipients. This is an important observation, as operative intervention in these patients carries greater risk than surgical procedures in the general population. The higher operative risks in the transplant population are partly due to their immunosuppressed status and poor wound healing. Furthermore, no clear consensus exists on the optimal management of PI. Various treatment strategies such as bowel rest, antibiotics, and parenteral feeding have been implemented with similar levels of success. With the increasing use of solid organ transplantation, PI is being recognized with increasing frequency. In this review, we provide a summary of the incidence, presentation, diagnosis, and management of PI, particularly as it affects recipients of solid organ transplantation.

Somatic clonal expansion refers to the proliferation and expansion of a cell clone within a multicellular organism. Since cancer also results from the uncontrolled proliferation of few cell clones, it is generally believed that aging-associated somatic clonal expansion observed in normal tissues represents a precancerous condition. For instance, hematological malignancy is often preceded by clonal hematopoiesis.

Background: It remains unclear whether physicians should accept transplantation offers for candidates with a positive SARS-CoV-2 reverse transcription polymerase chain reaction test due to the potential risk of severe infection after initiating immunosuppressive therapy.
Methods: A multicenter observational study was conducted in 19 French solid organ transplantation units. Patients on the waiting list for liver or kidney transplants who had a positive SARS-CoV-2 reverse transcription polymerase chain reaction nasopharyngeal swab at the time of transplantation were recorded.

Dominant narratives of solid-organ transplantation foreground vocabularies of gratitude. Solid-organ transplantation is often celebrated in biomedicine for its high-tech innovation and specialization. But transplantation also includes the organizations that oversee the distribution of donated organs to potential recipients who disproportionately outnumber available organs.

Background: Langerhans cell histiocytosis (LCH) is a rare disease, most prevalent in children. Ultrasound is a noninvasive, cheap, and widely available technique. However, systematic elucidation of sonographic features of LCH and treatment related follow-up are relatively few, resulting in overall underestimation of the clinical value of ultrasound in diagnosing and monitoring LCH.
