Rare bilateral vascular variations of the upper limb: a cadaveric case study.
J Cardiothorac Surg
December 2024
Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.
View Article and Find Full Text PDFTicks are a significant threat to livestock globally, with certain species displaying distinct host preferences at various developmental stages. Accurate species-level identification is essential for studying tick populations, implementing control strategies, and understanding disease dynamics. This study evaluated ticks infesting cattle across six provinces in South Africa using morphological and molecular methods.

- The study explores how a history of mental disorders, especially PTSD, influences the severity of PTSD symptoms in people affected by earthquakes, highlighting the need for better understanding in treatment.
- Researchers compared individuals with prior mental disorders to those without and found that those with any past mental issues tend to experience more current psychological disorders.
- The results indicate that while prior PTSD patients faced more life challenges, the presence of any previous mental disorder doesn't necessarily lead to more severe PTSD, suggesting the importance of screening for all trauma survivors, regardless of their mental health history.
Infantile hemangiomas (IH) are the most common benign tumors of infancy and progress through recognized stages of evolution including early proliferation, plateau, and involution. Ulceration is a common complication of IHs typically observed during the early proliferative stage characterized by rapid growth. In rare cases, ulceration is the primary clinical manifestation of IHs.

The purpose is to extend on quantitative findings in a previously described survey to gain a more in-depth understanding of Australian elementary teachers' approaches to the literacy block in their schools: how this is used, who makes instructional decisions, and how teachers respond to these.
Method: A web-based survey was used to collect data from Australian elementary teachers about their perspectives regarding reading comprehension instruction.
