Two patients with symptomatic congenital portal vein (PV) fistulas (one case of PV-right hepatic vein fistula and one case of PV-inferior vena cava fistula) causing hepatopulmonary syndrome (hepatic dysfunction, lung vascular alteration in the form of arteriovenous shunts, and hypoxemia) were successfully treated with the Amplatzer patent ductus arteriosus (PDA) occlusion device. This device was chosen in light of the anatomic characteristics of the vascular malformations and the specific properties of the prosthesis, especially those related to relocation and retrievability when not properly positioned. Embolization with an Amplatzer PDA occlusion device should be considered as a useful therapeutic alternative in the treatment of congenital portal fistulas that can obviate complex surgeries.

Electroencephalographic Features of Presumed Hepatic Encephalopathy in a Pediatric Dog with a Portosystemic Shunt-A Case Report.

Hepatic encephalopathy (HE) in dogs is a metabolic disorder of the central nervous system that occurs secondarily to liver dysfunctions, whether due to acquired or congenital causes. A portosystemic shunt is the presence of abnormal communications between the hepatic vessels (portal and suprahepatic veins). As a result of this, the blood brought from the digestive tract through the portal vein bypasses the liver, and the unmetabolized components of the portal bloodstream enter directly into systemic circulation, causing clinical symptoms of metabolic encephalopathy (HE).

Background: Congenital heart disease (CHD) is the most common birth defect, affecting 40,000 births annually in the United States. Despite advances in medical care, CHD is often a chronic condition requiring continuous management and education. Effective care management depends on children's understanding of their condition.

Ultrasound Unit, Helen Schneider Hospital for Women, Rabin Medical Center, Beilinson Hospital, Petach Tikva, Israel.
Objective: Portosystemic shunts in growth-restricted fetuses are more common than previously thought. We aimed to describe fetuses with growth restriction and transient oligohydramnios in which a congenital intrahepatic portosystemic shunt (CIPSS) was noted during follow-up.
Methods: This was a retrospective study of all fetuses diagnosed with growth restriction and transient oligohydramnios during a 5-year period in a large tertiary referral center.
Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders.
Andrology
January 2025
Section of Endocrinology and Investigative Medicine, Imperial College London, London, UK.
The hypothalamic-pituitary-gonadal axis is regulated by the gonadotropin-releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and gametogenesis from the gonads. Many reproductive disorders in both males and females are characterized by hypothalamic dysfunction, including functional disorders (such as age-related hypogonadism, obesity-related secondary hypogonadism, hyperprolactinemia, functional hypothalamic amenorrhea and polycystic ovary syndrome), structural pathologies (such as craniopharyngiomas or radiation or surgery-related hypothalamic dysfunction), and pubertal disorders (constitutional delay of growth and puberty and congenital hypogonadotropic hypogonadism).

J Vet Intern Med
January 2025
Cummings School of Veterinary Medicine at Tufts University, North Grafton, Massachusetts, USA.
Background: Dogs with hepatocutaneous syndrome (HCS) have marked plasma hypoaminoacidemia, but its occurrence in dogs with chronic liver diseases not associated with HCS (non-HCS CLD) is unknown.
Objectives: To determine if plasma hypoaminoacidemia occurs in dogs with non-HCS CLD, compare plasma amino acid (PAA) profiles between dogs with non-HCS CLD and HCS, and define a sensitive and specific PAA pattern for diagnosing HCS.
Animals: Data were collected from client-owned dogs, a prospective cohort of 32 with CLD and 1 with HCS, and a retrospective cohort of 7 with HCS.
