The significance of the meniscal flounce sign in canine stifle arthroscopy.

Objective: To determine the diagnostic significance of the meniscal flounce sign in association with meniscal tears.

Study Design: Prospective cohort study.

Sample Population: One hundred and thirty stifles in 120 client-owned dogs that underwent stifle arthroscopy.

Structural renal abnormalities in the DICER1 syndrome: a family-based cohort study.

Background: The DICER1 syndrome is a tumor-predisposition disorder caused by germline pathogenic variation in DICER1 and is associated with cystic nephroma and other renal neoplasms. Dicer1 mouse and rare human DICER1 syndrome case reports describe structural kidney and collecting system anomalies. We investigated renal function and the frequency of structural abnormalities of the kidney and collecting system in individuals with germline loss-of-function variants in DICER1.

Immediate, short-, and long-term changes in tracheal stent diameter, length, and positioning after placement in dogs with tracheal collapse syndrome.

Background: Intraluminal tracheal stenting is a minimally invasive procedure shown to have variable degrees of success in managing clinical signs associated with tracheal collapse syndrome (CTCS) in dogs.

Objectives: Identify immediate post-stent changes in tracheal diameter, determine the extent of stent migration, and stent shortening after stent placement in the immediate-, short-, and long-term periods, and evaluate inter-observer reliability of radiographic measurements.

Animals: Fifty client-owned dogs.

ACR Appropriateness Criteria Fever Without Source or Unknown Origin-Child.

The cause of fever in a child can often be determined from history, physical examination, and laboratory tests; infections account for the majority of cases. Yet in 20%, no apparent cause can be found, designated as fever without source (FWS). The yield of chest radiography in children with FWS is low, and it is usually not appropriate.

ACR Appropriateness Criteria Vomiting in Infants up to 3 Months of Age.

Vomiting is a commonly reported symptom in infants less than three months of age. There are a multitude of pathologies to consider, both within and outside the gastrointestinal tract. In addition to conducting a thorough history and physical examination, a clinician formulates a reasonable differential diagnosis by consideration of two main factors: the infant's age and the characterization of the vomit as bilious or nonbilious.
