Insights

Patients with PHACE syndrome and periocular infantile hemangiomas require comprehensive eye exams. Ocular complications, though rare, can be serious, emphasizing the need for vigilance in these cases.

Area of Science:

  • Ophthalmology
  • Pediatrics
  • Genetics

Background:

  • PHACE syndrome is a complex condition involving multiple congenital anomalies.
  • Infantile hemangiomas are common in infants and can occur in various locations.

Purpose of the Study:

  • To evaluate the risk and types of ocular complications in patients diagnosed with PHACE syndrome.
  • To determine the association between infantile hemangioma location and ocular issues in PHACE syndrome.

Main Methods:

  • Retrospective review of consecutive patients with PHACE syndrome from 2000-2017.
  • Comprehensive ophthalmic examinations were performed on all included patients.

Main Results:

  • Twenty-one percent of patients had periocular infantile hemangiomas, leading to ocular complications like ptosis and refractive errors in 9 patients.
  • One patient experienced Horner syndrome, an ocular complication specifically linked to PHACE syndrome.
  • No ocular complications were observed in patients without periocular infantile hemangiomas.

Conclusions:

  • A complete eye examination is crucial for PHACE syndrome patients with periocular infantile hemangiomas.
  • While PHACE syndrome-specific ocular anomalies are uncommon, secondary complications from hemangioma location can be significant.
  • Eye screening may have low yield in PHACE syndrome patients without periocular infantile hemangiomas.

True Stress and True Strain01:28

True Stress and True Strain

Engineering stress is calculated as the load divided by the original, undeformed cross-sectional area. It approximates a material under load. This approximation is especially relevant post-yield in ductile materials. Though engineering stress-strain diagrams are often used for their convenience and accessibility, they can sometimes fall short in accuracy, particularly when dealing with large strain values.
In contrast, true stress offers a more precise portrayal. It is computed by dividing the...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning01:27

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
