An anatomical and clinical study aimed at uncovering factors likely to be helpful in understanding the true nature of haemorrhoids is described. The main finding was of specialized 'cushions' of submucosal tissue lining the anal canal; it is argued that piles are merely the result of their displacement.

An anatomic survey of anomalous pulmonary veins: their clinical significance.

Dorsiflexion, palmar flexion, ulnar translocation, and dorsal carpal subluxation are four, not uncommon, post-traumatic carpal ligamentous instabilities. Palmar carpal subluxation is a theoretical possibility. Dorsiflexion and palmar flexion instabilities are named for the way the distal lunate articular surface faces, dorsally and palmarly, respectively. Ulnar translocation, and dorsal and ventral carpal subluxations are named according to movement of the entire carpus at the radiocarpal joint. Early detection of traumatic carpal instabilities is necessary to encourage optimal treatment of these significant carpal malalignments. These and other patients with disabling wrist problems may be evaluated by a “ligamentous instability series.”

In recent times new surgical approaches have been developed, in which subcutaneous tissue is the primary object, such as flaps and fat removal techniques, but different descriptions and abundance of terminology persist in Literature about this tissue. In order to investigate the structure of abdominal subcutaneous tissue, macroscopic and microscopic analyses of its layers were performed in 10 fresh cadavers. Results were compared with in vivo CT images of the abdomen of 10 subjects. The subcutaneous tissue of the abdomen comprises three layers: a superficial adipose layer (SAT), a membranous layer, and a deep adipose layer (DAT). The SAT presented fibrous septa that defined polygonal-oval lobes of fat cells with a mean circularity factor of 0.856 ± 0.113. The membranous layer is a continuous fibrous membrane rich in elastic fibers with a mean thickness of 847.4 ± 295 μm. In the DAT the fibrous septa were predominantly obliquely-horizontally oriented, defining large, flat, polygonal lobes of fat cells (circularity factor: mean 0.473 ± 0.07). The CT scans confirm these findings, showing a variation of the thickness of the SAT, DAT and membranous layer according with the subjects and with the regions. The distinction of SAT and DAT and their anatomic differences are key elements in modern approaches to liposuction. The membranous layer appears to be also a dissection plane which merits further attention. According with the revision of Literature, the Authors propose that the term “superficial fascia” should only be used as a synonym for the membranous layer.

Layers of the abdominal wall: anatomical investigation of subcutaneous tissue and superficial fascia

THE cavernous sinus is a vascular channel of great importance not only in ophthalmology but in many other branches of medicine. Descriptions of its structure are scattered in books and journals on ophthalmology, otorhinolaryngology, paediatrics, and dentistry as well as in the standard anatomical works. However, the descriptions of the sinus and its contents show great variation and it is the purpose of this paper to clarify the matter. Probably the earliest description of this sinus was by Ridley (1695), who placed the internal carotid artery against the lateral wall, \"leaving no room at all for either blood or serum to be contained there\". He noted with regard to the artery \"a little interstice between itselfand the pituitary gland\", and how this venous space communicated with that of the opposite side. The term \"circular sinus\" was suggested in his book, a name still sometimes applied. The presence of the fibrous trabeculae was first noted by Winslow (1732), but his description of the other structures is not clear: \"The internal carotid is bathed in the blood of the sinus together with the third, fourth, fifth and sixth pairs of nerves.\" It was Winslow who likened the interior of the sinus to that of the corpus cavernosum of the penis and applied the term \"cavernous\", which has been used ever since. The classic description is that of a blood-filled channel completely surrounding the horizontal portion ofthe internal carotid artery and the sixth (abducent) nerve as they pass anteriorly on either side of the sella turcica (Fig. 1). In addition to these two structures, the lumen of the cavernous sinus is usually described as being crossed by numerous fibrous laminae, termed trabeculae, and always depicted as a dense, interlacing mass. This description of the artery, the sixth nerve, and the trabeculae is given in most books dealing with anatomy: Thane (1892), Whitnall (1921), Sobotta (1928), Huber (1930), Spalteholz (1933), Wood Jones (1949), Wolff (1954), Boileau Grant (1958), and in the many applied and clinical works: Mosher (1914), Turner and Reynolds (1926), Campbell (1933), Fabricant (1933), Pace (1941), Herzig (1945), Orton (1947), Elfman (1950), Shaw (1952), Hollinshead (1954), Last (1959), and Duke-Elder (1961). Indeed, the presence of the trabeculae has
