BackgroundAppendicitis is the most common indication for an emergency operation in children's age. Although none of the laboratory values has not high sensitivity and specificity for the diagnosis of appendicitis, leukocyte count and the percentage of segmented neutrophils are most commonly used. The aim of this study was to determine whether there is a statistically significant correlation bet...

Soft, pneumatic actuators that buckle when interior pressure is less than exterior provide a new mechanism of actuation. Upon application of negative pneumatic pressure, elastic beam elements in these actuators undergo reversible, cooperative collapse, and generate a rotational motion. These actuators are inexpensive to fabricate, lightweight, easy to control, and safe to operate. They can be u...

In this retrospective, interventional case report of a 40 year-old woman with Stickler Syndrome, we present a novel use of dermis fat graft to manage an externally exposed scleral buckle that was refractory to other methods of management. Dermis fat graft is a relatively robust material that can be effectively utilized to rescue an exposed scleral buckle. This case presentation conforms to the ...

An audit of fracture clinic referrals from the Paediatric Emergency Department demonstrated a large proportion of patients referred had not suffered a fracture or significant injury. A strategy for managing distal forearm (radius and/or ulna) buckle fractures was developed with the goals of reducing overall fracture clinic referrals and reducing the number of non-significant injuries referred t...

Purpose: To describe the clinical characteristics and surgical outcomes of patients with myopic tractional maculopathy (MTM) who underwent macular buckling (MB) surgery using a novel L-shaped buckle.Methods: A titanium stent, style 507 sponge, silicone sleeve were used to create an buckle. The stent was bent through 90° over last third. sponge cut about 1 cm in length placed on extremity. remai...

We introduce a class of continuum shell structures, the Buckliball, which undergoes a structural transformation induced by buckling under pressure loading. The geometry of the Buckliball comprises a spherical shell patterned with a regular array of circular voids. In order for the pattern transformation to be induced by buckling, the possible number and arrangement of these voids are found to b...
