The position of a duodenal diverticulum in the area of the major duodenal papilla and its potential clinical implications.

Background: Although duodenal diverticula are associated with less frequent pathology than the colonic diverticula in the large intestine, their periampullary position may have significant clinical implications. The aim of the study was to identify any possible correlation between the type of localisation of the major duodenal papilla, duodenal diverticula, and some particular clinical issues.

Materials And Methods: In total, 628 patients (408 females and 220 males; aged 21-91 years), who underwent endoscopic retrograde cholangiopancreatography were included in this study.

Anatomical variations of the abductor pollicis longus: a pilot study.

Background: The abductor pollicis longus (APL) originates from the lateral part of the dorsal surface of the body of the ulna below the insertion of the anconeus muscle, from the interosseous membrane, and from the middle third of the dorsal surface of the body of the radius. However, the number of its accessory bands and their insertion vary considerably.

Materials And Methods: Fifty upper limbs (2 paired, 31 male, 19 female) were obtained from adult Caucasian cadavers, and fixed in 10% formalin solution before examination.

Anatomical variations of the levator palpebrae superioris, including observations on its innervation and intramuscular nerves' distribution pattern.

Background: The levator palpebrae superioris muscle (LPS) acts as the upper eyelid's major elevator and retractor and is innervated by the oculomotor nerve. The muscle's paralysis is manifested by ptosis.

Material And Methods: 70 orbits were dissected.

The Superficial Venous System of the Forelimb of the Anubis Baboon (): The Distribution of Perforating Veins and Venous Valves.

The superficial veins of the forelimb show high variability, both in man and in other primates, regarding the number of main venous trunks, their course, as well as the origin and location of openings. The distinction between two venous systems-the superficial and deep was made based on the relation of specific venous channels to the deep fascia; both groups of veins anastomose to each other through perforators piercing the deep fascia. In our work, we paid special attention to the organization of the venous system within the forelimb of the Anubis baboon (), as well as communications between the superficial and deep venous system.

Anatomical Variations of the Supraorbital and Supratrochlear Nerves: Their Intraorbital Course and Relation to the Supraorbital Margin.

BACKGROUND This study aimed to describe the topographical anatomy of the supraorbital and supratrochlear nerves. Anatomical variations of both the intraorbital course of the 2 nerves and their relation to the supraorbital margin were analyzed. MATERIAL AND METHODS The research material involved 50 isolated adult cadaveric hemi-heads and 25 macerated adult skulls.
