The Renaissance
Published in Scott M. Jackson, Skin Disease and the History of Dermatology, 2023
Mercurialis addressed what he considered to be common diseases, achor and favus, described as two types of ulcerative scalp diseases that he classified as moist types, as opposed to the dry type of scalp ulcers that he terms tinea.71Achor and favus are characterized by an exudation of sticky humors. Achor has small openings from which a thin exudate oozes, while favus has larger openings and a thicker, honey-like exudate (favus, Latin for honeycomb). The former term is no longer used today but probably represented an infected form of scalp dermatitis, whereas favus now refers to a rare type of tinea capitis (scalp ringworm). According to Mercurialis, both conditions begin with itching, then swelling in response to scratching, and subsequent oozing. He preferred Galen's opinion that the cause of these scalp diseases was an “acrid, serous, erosive humor mixed with a thick one” and that tasting and touching the humor could aid in the diagnosis. If the humor tastes slightly bitter, the source is bile; if acid, phlegm or melancholy. If the ulcer feels warm, the disease is bilious, and if cold, phlegmatic.72Achor and favus of the child are treated primarily with topical remedies; for adults, bloodletting followed by purging and then the application of topical liniments (lotion) is the treatment protocol. For bloodletting, he recommended venesection of the frontal or postauricular veins if the condition is extensive as opposed to the more traditional use of the common ulnar vein.
A review of upper extremity deep vein thrombosis

UEDVT is defined as the formation of a thrombus within the deep venous system of the arm. The deep venous system includes the subclavian, axillary, brachial, radial, ulnar, and interosseous veins (see Figure 1). This anatomical definition must further be refined by clinical relevance. Distal UEDVT i.e. ulnar, radial, and interosseous venous thromboses are generally asymptomatic and no guidelines recommend evaluation or treatment for these entities. Because of that, the term UEDVT is often reserved for thromboses with clinical relevance i.e. subclavian, axillary, and brachial vein thromboses. Although there are extremely rare case reports of isolated sym`ptomatic radial and ulnar vein thromboses [1,2], for the purpose of this review, UEDVT will encompass subclavian, axillary, and brachial vein thromboses.
Technique of percutaneous closure of an endovascular arteriovenous fistula created for dialysis access
Published in Baylor University Medical Center Proceedings, 2023
Surgical AVFs are classically created in the easier to approach radial or brachial artery, but the common ulnar artery is difficult to approach surgically.10 eAVFs are frequently commonly created between the common ulnar artery (segment between the brachial bifurcation and prior to the takeoff of the interosseus and proper ulnar artery) and medial ulnar vein5 secondary to the larger size of both the common ulnar arteries and veins in this area. This endovascular advantage in access to the ulnar artery during eAVF creation translates similarly for the patient in this case report when considering approaches to occlusion of eAVFs.

The study participants were genotyped using the polymorphic marker of the Clock 3111T/C gene (rs1801260). The material for the study was the wholesome venous blood samples taken from the ulnar vein into tubes with K3-EDTA anticoagulant. Subsequently the extraction of genomic DNA from the blood samples was carried out using the “AmpliPrime DNA-Sorb-B” reagent kit (“Nekstbio”, Russia). The polymorphic marker was determined through polymerase chain reaction method on the “DT-Prime” (“DNA-Technology”, Russia) amplifier using reagent sets for genotyping polymorphic markers (“TestGen”, Russia).
