Assisted reproductive technologies (ARTs) have been proposed as a means of overcoming the significant challenges of managing small, isolated populations of endangered species in zoos. However, efficient protocols for ARTs do not exist for most endangered species. This review will focus on research efforts to characterize unique reproductive mechanisms and develop species-specific ARTs. Central to these studies are assays to measure steroid metabolites in urine or feces and/or training programs to allow un-restrained blood collections and ultrasound evaluations...

The need for temporary cardiac pacing may occur in emergency and elective situations and may require transvenous right ventricular lead placement. The treatment of bradyarrhythmias presents the most common perioperative emergency indication. Intraoperatively, temporary rapid right ventricular pacing is accepted as a safe, titratable, and highly reliable method to achieve deliberate hypotension, and it has become a routine practice in the anesthetic management of cardiovascular interventions. The navigation of the lead into the right ventricle often requires fluoroscopy to guide placement and to confirm position...

BACKGROUND: Traumatized patients are at risk of developing Deep Vein Thrombosis (DVT) and DVT prophylaxis is the standard of care. The Centers for Medicare and Medicaid Services classifies DVT as a Hospital Acquired Condition and can deny payment for treatment of DVT and, in addition, place financial penalties on hospitals with higher than acceptable rates of DVT, unless the DVT was pre-existing. We sought to determine the rate of pre-existing chronic DVT among symptomatic traumatized inpatients at our ACS-verified Level 1 trauma center...

Renal cell carcinoma (RCC) is known for having unpredictable clinical behavior. Metastases can occur in unusual locations with a long-time lag after the treatment of the primary cancer. Despite being a sign of poor prognosis, aggressive metastasectomy may prolong survival. Presented is a case of delayed sequential metastases of RCC to the pancreas and the thyroid gland that occurred eight years after the radical nephrectomy. Both were resected. A history of remote nephrectomy for RCC is important and may be suggestive of metastatic disease...

The growing awareness of Fontan-associated liver disease (FALD) in adults with Fontan physiology has provided the impetus to better understand the natural history of FALD and develop a reliable noninvasive method to diagnose and monitor liver health in this population. Biochemical and imaging tests have been investigated to determine their association with liver pathology. The congestive hepatopathy that develops after the Fontan procedure has made interpreting these tests challenging. We have reviewed and summarized the current understanding and ongoing challenges with respect noninvasive measures of liver health in Fontan patients including biochemical tests, elastography, hepatic ultrasound, cross-sectional imaging, and hemodynamics and how they relate to liver pathology...

The study of the gastrointestinal tract by imaging, particularly using ultrasound, is a required instrument for diagnosis of acute and chronic gastrointestinal pathologies in pediatric age. Actually, ultrasound plays an increasing role in the evaluation of gastrointestinal tract in neonatal and pediatric patients because of their small body habitus and the presence of less fat tissue in the abdominal wall and peritoneal cavity. Ultrasound has certain advantages, thanks to the new wide-spectrum frequency probes able to assess a detailed study of the morphological aspects and functional characteristics of bowel loops, adding a new dimension to the imaging of this body system...

CffDNA screening is a powerful diagnostic tool in the prenatal diagnosis algorithm for chromosomal abnormalities. With detailed ultrasound examination as the mainstay of first-trimester risk assessment, cffDNA has been shown to be superior to first-trimester combined screening (FTCS) in false-positive rates for trisomy 21 detection. In light of the growing interest in cffDNA testing and the possibility of it replacing first-trimester biochemistry, we decided to investigate the usefulness of cffDNA tests in early-pregnancy risk assessment for preeclampsia (PE)...
