Diagnostic Imaging in Surgery
No full textThe World Health Organization recommended that the minimum standard radiological equipment is about 20 general radiography units per million people, suggested that approximately 1 Computed Tomography (CT) scan is required for every 10 general radiography units. The X-ray units are the most equitably distributed and accessible resources in low-and middle income countries. Ultrasound (US) use has increased due to improved portability, durability and decreased costs of machines. When CT is not available, patients presenting with generalized acute abdominal pain should undergo a supine abdominal radiography with an erect chest x-ray to confirm a perforated viscus or a bowel obstruction. When CT is available, the abdominal radiography is indicated only in case of foreign body search and confirmation of fecal impaction in the elderly. US examination is the imaging of choice in case of right upper quadrant pain to confirm acute cholecystitis and explore the biliary tree and the liver; in gynecologic and pelvic diseases, in the suspicion of acute appendicitis or to search for abscesses anywhere in the abdomen or pelvis, and in renal colic to assess hydronephrosis. When the contrast enhanced CT is available, it is the imaging technique mandatory to make diagnosis in certain life threatening gastrointestinal emergencies such as in case of acute mesenteric ischemia, gastrointestinal perforation, obstruction. Surgical exploration is mandatory in hemodynamically unstable patients presenting with acute abdomen
Prosthetic abdominal wall hernia repair in emergency surgery: from polypropylene to biological meshes
No full textAbstract The use of nonabsorbable prosthetic materials such as polypropylene, polyester, and ePTFE, have expanded and are now widely used in reparative surgery for abdominal wall hernias. There are still difficulties to find correct indication for prosthetic implant in emergency hernia surgery: as a matter of fact there is still a great debate if to use non-absorbable prostheses in potentially or truly infected operating fields [e.g. after intestinal resections]. All these problems can be avoided with the use of absorbable prosthetic materials such as those composed of lactic acid polymers or lactic and glycolic acid copolymers: however, the use of these absorbable prosthesis exposes the patient to a rapid and inevitable hernia recurrence. It is important to remember that prosthetic repair has been proven to have a significant less risk of recurrence than repair with direct sutures. Recently, new "biologic" prosthetic materials have been developed and proposed for the clinical use in infected fields. These materials can be called "remodeling" for the way by which they are replaced after their placement within the patient. The "remodeling" process is made possible through a process of incorporation, where a reproduction of a site-specific tissue similar to the original host tissue is created.</p

No full textOn two narwhal teeth (Monodon monoceros L. 1758) from the Museum of Zoology and Comparative Anatomy of Modena University. There are two narwhal teeth among the finds of the Museum of Zoology and Comparative Anatomy of Modena University, whose acquisition is unknown. Their high value induce us to believe that some noble or high-ranking middle-class person bequeathed them. Archive research, carried out on the inventory of 1751 regarding the finds kept in the Medals’ Gallery of the Dukes’ Palace, discovered a narwhal tooth placed on a pedestal for show. During the French occupation of 1796, the collections of the Dukes’ Palace were looted and dispersed. Some of the paintings and bronze and marble statues were given to the school of Fine Arts, whereas the finds of naturalistic interest were donated to the Museum of Natural History of Modena University. The best paintings, precious coins, cut gems etc. were sent to France. After the Restauration, Duke Francesco IV presented most of the naturalist finds that had been taken away to the Museum of Natural History. Among these finds, there was also the narwhal tooth previously described. There are no data about another narwhal tooth, although it probably belonged to the Duke’s collections and was kept in another part of the palace or in another residence

Editorial: New Frontiers for Artificial Intelligence in Surgical Decision Making and its Organizational Impacts
No full textThe purpose of the research topic call “New Frontiers for Artificial Intelligence in Surgical Decision Making and its Organizational Impacts “ was to collect the recent developments and undergoing studies in AI in surgery and surgical oncology. More in detail, the aim was to gather contributions on the advancement, deployment, use, and implementation of AI-based applications in surgical practice, understanding their potential contribution to clinical decision making. Moreover, the idea was to assess the potential impacts of such a technology on surgeons, other clinicians, patients, medical institutions, developers, and policy-makers, with an eye open to the organizational and educational consequences and opportunities
Poly(1-trimethylsilyl-1-propyne)-based hybrid membranes: Effects of various nanofillers and feed gas humidity on CO2 permeation
No full textPoly(1-trimethylsilyl-1-propyne) (PTMSP) is a high free volume polymer with exceptionally high gas permeation rate but the serious aging problem and low selectivity have limited its application as CO2 separation membrane material. Incorporating inorganic nanoparticles in polymeric membranes has been a common approach to improve the separation performance of membranes, which has also been used in PTMSP based membrane but mostly with respect to tackling the aging issues. Aiming at increasing the CO2 selectivity, in this work, hybrid membranes containing four types of selected nanofillers (from 0 to 3D) were fabricated using PTMSP as the polymer matrix. The effects of the various types of nanofillers on the CO2 separation performance of the resultant membranes were systematically investigated in humid conditions. The thermal, chemical and morphologic properties of the hybrid membranes were characterized using TGA, FTIR and SEM. The gas permeation properties of the hybrid membranes were evaluated using mixed gas permeation test with the presence of water vapour to simulate the flue gas conditions. Experiments show that the addition of different fillers results in significantly different separation performances; The addition of ZIF-L porous 2D filler improves the CO2/N2 selectivity at the expenses of CO2 permeability, while the addition of TiO2, ZIF-7 and ZIF-8 increases the CO2 permeability but the CO2/N2 selectivity decreases
