Abdominopelvic tumors of infancy: a pictorial essay.

Abdominal and pelvic masses in infants present significant challenges for healthcare professionals and can be distressing for parents due to the wide spectrum of both benign and malignant conditions in this age group. This article concentrates on illustrating different types of abdominal and pelvic tumors, both benign and malignant, that occur in infants. It highlights the specific imaging characteristics of these tumors and covers non-neoplastic conditions that may appear similar on imaging.

Acute Kidney Injury and Diffuse Pulmonary Hemorrhage Secondary to IgA Nephropathy and Henoch-Schönlein Purpura: A Case Report.

IgA nephropathy (IgAN), characterized as immune complex-mediated glomerulonephritis, can occasionally manifest alongside the pulmonary-renal syndrome. Henoch-Schönlein purpura (HSP), an inflammatory condition affecting small vessels through leukocytoclastic vasculitis, exhibits a close association with IgA nephropathy. Nonetheless, HSP's infrequent complications encompass pulmonary hemorrhage.

The Diagnostic and Therapeutic Dilemma of Seronegative Pulmonary Renal Syndrome: A Case Report.

Pulmonary renal syndrome (PRS) is a combination of rapid progressive glomerulonephritis (RPGN) and diffuse alveolar hemorrhage (DAH) caused by a variety of immunological and non-immunological etiologies. The difficulty in identifying and reporting seronegative PRS cases could be attributed to the lack of specific immunological markers. Thus, we report a rare case of a 13-year-old boy who was initially diagnosed with idiopathic pauci-immune pulmonary capillaritis (IPIPC).

Clinical and epidemiological aspects of herpes zoster disease in a primary care setting in Riyadh, Saudi Arabia: A retrospective cohort study.
